PART I

Item 1.    Business

GENERAL

        Ares Capital Corporation, a Maryland corporation (together with its subsidiaries, where applicable, "Ares Capital" or the "Company," which may also be referred to as "we," "us" or "our"), is a specialty finance company that is a closed-end, non-diversified management investment company. We have elected to be regulated as a business development company, or a "BDC," under the Investment Company Act of 1940, as amended, and the rules and regulations promulgated thereunder or the "Investment Company Act." We were founded on April 16, 2004, were initially funded on June 23, 2004 and completed our initial public offering on October 8, 2004. We are one of the largest BDCs with approximately $5.4 billion of total assets and $15 billion of total committed capital under management as of December 31, 2011, including available debt capacity (subject to leverage and borrowing base restrictions), vehicles directly or indirectly managed or co-managed by us or one of our wholly owned subsidiaries and vehicles managed or sub-managed by our wholly owned portfolio company, Ivy Hill Asset Management, L.P. ("IHAM").

        We are externally managed by our investment adviser, Ares Capital Management LLC ("Ares Capital Management" or our "investment adviser"), a wholly owned subsidiary of Ares Management LLC ("Ares Management"), a global alternative asset manager and a Securities and Exchange Commission ("SEC") registered investment adviser with approximately $46 billion of total committed capital under management as of December 31, 2011. Ares Operations LLC ("Ares Operations" or our "administrator"), our administrator, a wholly owned subsidiary of Ares Management, provides the administrative services necessary for us to operate.

        Ares Capital's investment objective is to generate both current income and capital appreciation through debt and equity investments. We invest primarily in U.S. middle-market companies, where we believe the supply of primary capital is limited and the investment opportunities are most attractive. However, we may from time to time invest in larger companies. We generally use the term "middle-market" to refer to companies with annual EBITDA between $10 million and $250 million. As used herein, EBITDA represents net income before net interest expense, income tax expense, depreciation and amortization.

        On April 1, 2010, we consummated our acquisition (the "Allied Acquisition") of Allied Capital Corporation ("Allied Capital") in an all stock merger whereby each existing share of common stock of Allied Capital was exchanged for 0.325 shares of our common stock. The Allied Acquisition was valued at approximately $908 million as of April 1, 2010. In connection therewith, we issued approximately 58.5 million shares of our common stock to Allied Capital's then-existing stockholders, thereby resulting in our then-existing stockholders owning approximately 69% of the combined company and the then-existing Allied Capital stockholders owning approximately 31% of the combined company.

        We invest primarily in first and second lien senior loans and mezzanine debt, which in some cases includes an equity component. First and second lien senior loans generally are senior debt instruments that rank ahead of subordinated debt of a given portfolio company. Mezzanine debt is subordinated to senior loans and is generally unsecured. Our investments have generally ranged between $20 million and $250 million each, although the investment size may be more or less than this range. Our investment sizes are expected to grow with our capital availability.

        To a lesser extent, we also make preferred and/or common equity investments, which have generally been non-control equity investments of less than $20 million (usually in conjunction with a concurrent debt investment). However, we may increase the size or change the nature of these investments. Also, as a result of the Allied Acquisition, Allied Capital's equity investments, which included equity investments larger than those we have historically made and controlled portfolio

1

---

company equity investments, became part of our portfolio. We intend to continue actively seeking opportunities over time to dispose of certain of the assets that were acquired in the Allied Acquisition, particularly non-yielding equity investments and controlled portfolio company equity investments, as well as lower or non-yielding debt investments and investments that may not be core to our investment strategy, and generally rotate them into higher-yielding first and second lien senior loans and mezzanine debt investments. However, there can be no assurance that this strategy will be successful. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Portfolio and Investment Activity" for further information on the rotation of investments acquired as part of the Allied Acquisition.

        The proportion of these types of investments will change over time given our views on, among other things, the economic and credit environment we are operating in. In connection with our investing activities, we may make commitments with respect to indebtedness or securities of a potential portfolio company substantially in excess of our final investment. In such situations, while we may initially agree to fund up to a certain dollar amount of an investment, we may subsequently syndicate a portion of such amount to third parties, such that we are left with a smaller investment than what was reflected in our original commitment. In addition to originating investments, we may also acquire investments in the secondary market.

        The first and second lien senior loans in which we invest generally have stated terms of three to 10 years and the mezzanine debt investments in which we invest generally have stated terms of up to 10 years, but the expected average life of such first and second lien loans and mezzanine debt is generally between three and seven years. However, we may invest in loans and securities with any maturity or duration. The instruments in which we invest in typically are not initially rated by any rating agency, but we believe that if such instruments were rated, they would be below investment grade (rated lower than "Baa3" by Moody's Investors Service, lower than "BBB-" by Fitch Ratings or lower than "BBB-" by Standard & Poor's Rating Services). We may invest without limit in debt or other securities of any rating, as well as debt or other securities that have not been rated by any nationally recognized statistical rating organization.

        We believe that our investment adviser, Ares Capital Management is able to leverage the current investment platform, resources and existing relationships with financial sponsors, financial institutions, hedge funds and other investment firms of Ares Management and its affiliated companies to provide us with attractive investment opportunities. For the purposes of this document we refer to Ares Management and its affiliated companies (other than portfolio companies of its affiliated funds) as "Ares." In addition to deal flow, the Ares investment platform assists our investment adviser in analyzing, structuring and monitoring investments. Ares has been in existence for more than 14 years and its senior principals have an average of over 22 years experience investing in senior loans, high yield bonds, mezzanine debt and private equity securities. The Company has access to the Ares staff of approximately 225 investment professionals and approximately 250 administrative professionals who provide assistance in accounting, finance, legal, compliance, operations, information technology and investor relations.

        While our primary focus is to generate current income and capital appreciation through investments in first and second lien senior loans and mezzanine debt and, to a lesser extent, equity securities of eligible portfolio companies, we also may opportunistically invest up to 30% of our portfolio in non-qualifying assets, as permitted by the Investment Company Act. Specifically, as part of this 30% basket, we may invest in entities that are not considered "eligible portfolio companies" (as defined in the Investment Company Act), including companies outside of the United States, entities that are operating pursuant to certain exceptions to the Investment Company Act, and publicly traded entities whose public equity market capitalization exceeds the levels provided for in the Investment Company Act.

        We and General Electric Capital Corporation and GE Global Sponsor Finance LLC (collectively, "GE") also co-invest through an unconsolidated vehicle, the Senior Secured Loan Fund LLC, which operates using the name "Senior Secured Loan Program" (the "SSLP"). The SSLP was initially formed in December 2007 by Allied Capital and GE to co-invest in "stretch senior" and "unitranche" loans (loans that combine both senior and subordinated debt, generally in a first lien position) of middle-market companies. In October 2009, the Company completed its acquisition from Allied Capital of subordinated certificates issued by the SSLP and management rights in respect thereto. As of December 31, 2011, the SSLP had approximately $7.7 billion of available capital, approximately $5.0 billion in aggregate principal amount of which was funded as of December 31, 2011. At December 31, 2011, we had agreed to make available to the SSLP approximately $1.5 billion, of which approximately $1.1 billion was funded. The SSLP is capitalized as transactions are completed and all portfolio decisions and generally all other decisions in respect of the SSLP must be approved by both an affiliate of GE and the Company. As of December 31, 2011, our investment in the SSLP was approximately $1.1 billion at fair value (including unrealized appreciation of $24.9 million) which represented 20.8% of our total portfolio at fair value.

        In the first quarter of 2011, the staff of the SEC (the "Staff") informally communicated to certain BDCs the Staff's belief that certain entities, which would be classified as an "investment company" under the Investment Company Act but for the exception from the definition of "investment company" set forth in Rule 3a-7 promulgated under the Investment Company Act, could not be treated as eligible portfolio companies (as defined in Section 2(a)(46) of the Investment Company Act). Subsequently, in August 2011 the SEC issued a concept release (the "Concept Release") which states that "[a]s a general matter, the Commission presently does not believe that Rule 3a-7 issuers are the type of small, developing and financially troubled businesses in which Congress intended BDCs primarily to invest" and requested comment on whether or not a 3a-7 issuer should be considered an "eligible portfolio company". Ares Capital continues to believe that the language of Section 2(a)(46) of the Investment Company Act permits a BDC to treat as "eligible portfolio companies" entities that rely on the 3a-7 exception. However, given the current uncertainty in this area (including the language in the Concept Release), Ares Capital has, solely for purposes of calculating the composition of its portfolio pursuant to Section 55(a) of the Investment Company Act, identified such entities, which include the SSLP, as "non-qualifying assets" should the Staff ultimately disagree with Ares Capital's position.

        Our portfolio company, IHAM, manages 10 unconsolidated credit vehicles and sub-manages or sub-advises four other unconsolidated credit vehicles (these vehicles managed or sub-managed/sub-advised by IHAM are collectively referred to as the "IHAM Vehicles"), which are described in more detail under "Ares Capital Corporation Portfolio-Managed Vehicles". We have also made direct investments in securities of certain of these vehicles. As of December 31, 2011, IHAM had total committed capital under management of approximately $3.4 billion, which included approximately $0.3 billion invested by Ares Capital in IHAM or securities issued by the IHAM Vehicles.

        We manage an unconsolidated fund, AGILE Fund I, LLC (the "AGILE Fund"), which had approximately $62 million of total committed capital under management as of December 31, 2011.

About Ares

        Founded in 1997, Ares is a global alternative asset manager and SEC registered investment adviser with approximately $46 billion of total committed capital under management and over 470 employees as of December 31, 2011.

        Ares specializes in originating and managing assets in both the leveraged finance and private equity markets. Ares' leveraged finance activities include the origination, acquisition and management of senior loans, high yield bonds, mezzanine debt and special situation investments. Ares' private equity activities focus on providing flexible, junior capital to middle-market companies. Ares has the ability to

3

---

invest across a capital structure, from senior floating rate debt to common equity. This flexibility, combined with Ares' "buy and hold" philosophy, enables Ares to structure an investment to meet the specific needs of a company rather than the less flexible demands of the public markets.

        Ares is comprised of the following groups:

•

Private Debt Group.  The Ares Private Debt Group manages Ares Capital, Ares Credit Strategies Fund II, L.P., Ares Credit Strategies Fund III, L.P., Ares Mezzanine Partners, L.P., Ares' private debt middle-market financing business in Europe, Ares Capital Europe ("ACE"), as well as the Ares Commercial Real Estate business, which together had approximately $18.5 billion of total committed capital under management as of December 31, 2011, including capital which may be committed for investment both directly and through certain financial services portfolio companies of the Company. The Ares Private Debt Group focuses primarily on non-syndicated first and second lien senior loans and mezzanine debt, which in some cases may include an equity component. The Ares Private Debt Group also makes equity investments in private middle-market companies, usually in conjunction with a concurrent debt investment.



•

Capital Markets Group.  The Ares Capital Markets Group had approximately $22.2 billion of total committed capital under management as of December 31, 2011 through a variety of funds and investment vehicles, focusing primarily on syndicated senior secured loans, high yield bonds, distressed debt, other liquid fixed income investments and other publicly traded debt securities.



•

Private Equity Group.  The Ares Private Equity Group had approximately $5.6 billion of total committed capital under management as of December 31, 2011, primarily through Ares Corporate Opportunities Fund L.P., Ares Corporate Opportunities Fund II, L.P. and Ares Corporate Opportunities Fund III, L.P. (collectively referred to as "ACOF"). ACOF generally makes private equity investments in amounts substantially larger than the private equity investments anticipated to be made by Ares Capital. In particular, the Ares Private Equity Group generally focuses on control-oriented equity investments in under-capitalized companies or companies with capital structure issues.

        Ares' senior principals have been working together as a group for many years and have an average of over 22 years of experience in leveraged finance, private equity, distressed debt, investment banking and capital markets. They are backed by a large team of highly disciplined professionals. Ares' rigorous investment approach is based upon an intensive, independent financial analysis, with a focus on preservation of capital, diversification and active portfolio management. These fundamentals underlie Ares' investment strategy and have resulted in large pension funds, banks, insurance companies, endowments and certain high net worth individuals investing in Ares' funds.

Ares Capital Management

        Ares Capital Management, our investment adviser, is served by an origination, investment and portfolio management team of approximately 70 investment professionals led by the senior partners of the Ares Private Debt Group: Michael Arougheti, Eric Beckman, Kipp deVeer, Mitchell Goldstein and Michael Smith. Ares Capital Management leverages off of Ares' investment platform and benefits from the significant capital markets, trading and research expertise of Ares' investment professionals. Ares has approximately 225 investment professionals covering current investments in more than 1,100 companies across over 30 industries. Ares Capital Management's investment committee has eight members, including the senior partners of the Ares Private Debt Group, senior partners in the Ares Private Equity Group and a senior adviser to the Ares Capital Markets Group.

MARKET OPPORTUNITY

        We believe that current market conditions present attractive opportunities for us to invest in middle-market companies; specifically:

•

We believe that the dislocation in the credit markets that began in 2007 resulted in reduced competition, a widening of credit spreads, increased fees and generally more conservative capital structures and deal terms. These previous market conditions may continue to create favorable opportunities to invest at attractive risk-adjusted returns.



•

We believe that many commercial and investment banking lenders have, in recent years, de-emphasized their service and product offerings to middle-market businesses in favor of lending to large corporate clients and managing capital markets transactions. In addition, commercial and investment banks are limited in their ability to underwrite and syndicate bank loans and high yield securities for middle-market issuers as they seek to build capital and meet future regulatory capital requirements. These factors may result in opportunities for alternative funding sources to middle market companies and therefore more new-issue market opportunities.



•

We believe that there is a lack of market participants that are willing to not only underwrite but also hold loans. As a result, we believe our ability to minimize syndication risk for a company seeking financing by being able to hold such loans without having to syndicate them is a competitive advantage.



•

We believe there is a large pool of uninvested private equity capital for middle-market businesses. We expect private equity firms will seek to leverage their investments by combining equity capital with senior secured loans and mezzanine debt from other sources such as us.



•

We believe that the scheduled expirations of reinvestment periods for a significant amount of collateralized loan obligation vehicles may reduce the amount of funding available for larger middle market businesses over time.



•

A high volume of senior secured and high yield debt was originated in the calendar years 2004 through 2007 and will come due in the near term and, accordingly, we believe that new financing opportunities will increase as many companies seek to refinance this indebtedness.

COMPETITIVE ADVANTAGES

        We believe that we have the following competitive advantages over other capital providers to middle-market companies:

The Ares Platform

        As of December 31, 2011, Ares managed approximately $46 billion of total committed capital under management in the related asset classes of non-syndicated first and second lien senior loans, syndicated loans, high yield bonds, mezzanine debt and private equity. We believe Ares' current investment platform provides a competitive advantage in terms of access to origination and marketing activities and diligence for Ares Capital. Specifically, the Ares platform provides the Company an advantage through its deal flow generation and investment evaluation process. Ares' asset management platform also provides additional market information, company knowledge and industry insight that benefit the investment and due diligence process. Ares professionals maintain extensive financial sponsor and intermediary relationships, which provide valuable insight and access to transactions and information.

Seasoned Management Team

        Ares' senior professionals have an average of more than 22 years of experience in leveraged finance, including substantial experience in investing in leveraged loans, high yield bonds, mezzanine debt, distressed debt and private equity securities. The investment professionals in Ares' Private Debt Group and members of our investment adviser's investment committee also have significant experience originating and investing across market cycles. As a result of Ares' extensive investment experience and the history of its seasoned management team, Ares has developed a strong reputation across U.S. and European capital markets. We believe that Ares' long history in the leveraged loan market and the extensive experience of its principals originating and investing across market cycles provides Ares Capital with a competitive advantage in identifying, originating, investing in and managing a portfolio of investments in middle-market companies.

Experience and Focus on Middle-Market Companies

        Ares has historically focused on investments in middle-market companies and we benefit from this experience. In sourcing and analyzing deals, our investment adviser benefits from Ares' extensive network of relationships focused on middle-market companies, including management teams, members of the investment banking community, private equity groups and other investment firms with whom Ares has had long-term relationships. We believe this network enables us to identify well-positioned prospective portfolio company investments. The Ares Private Debt Group works closely with Ares' other investment professionals, who together currently oversee a portfolio of investments in over 1,100 companies across over 30 industries, and provide access to an extensive network of relationships and insights into industry trends and the state of the capital markets.

Disciplined Investment Philosophy

        In making its investment decisions, our investment adviser has adopted Ares' long-standing, consistent, credit-based investment approach that was developed over 22 years ago by its founders. Specifically, our investment adviser's investment philosophy, portfolio construction and portfolio management involve an assessment of the overall macroeconomic environment and financial markets and company-specific research and analysis. Its investment approach emphasizes capital preservation, low volatility and minimization of downside risk. In addition to engaging in extensive due diligence from the perspective of a long-term investor, our investment adviser's approach seeks to reduce risk in investments by focusing on:

•

businesses with strong franchises and sustainable competitive advantages;



•

industries with positive long-term dynamics;



•

businesses and industries with cash flows that are dependable and predictable;



•

management teams with demonstrated track records and appropriate economic incentives;



•

rates of return commensurate with the perceived risks;



•

securities or investments that are structured with appropriate terms and covenants; and



•

businesses backed by experienced private equity sponsors.

Extensive Industry Focus

        We seek to concentrate our investing activities in industries with a history of predictable and dependable cash flows and in which the Ares investment professionals have had extensive investment experience. Ares investment professionals have developed long-term relationships with management teams and management consultants in over 30 industries, and have accumulated substantial information

6

---

and identified potential trends within these industries. In turn, we benefit from these relationships, information and identification of potential trends in making investments.

Flexible Transaction Structuring and Scale

        We believe that being one of the largest BDCs with approximately $15 billion of total committed capital under management as of December 31, 2011, including available debt capacity (subject to leverage and borrowing base restrictions) and capital available through vehicles directly or indirectly managed or co-managed by us or one of our wholly owned subsidiaries and vehicles managed or sub-managed by certain financial services portfolio companies, makes us a more desirable and flexible capital provider, especially in competitive markets. We are flexible in structuring investments, including the types of investments and the terms associated with such investments. Ares has extensive experience investing in a wide variety of structures for companies with a diverse set of terms and conditions. We believe this approach and experience enables our investment adviser to identify attractive investment opportunities throughout economic cycles and across a company's capital structure so we can make investments consistent with our stated investment objective and preserve principal while seeking appropriate risk adjusted returns. In addition, we have the ability to provide "one stop" financing with the ability to invest capital across the balance sheet and syndicate and hold larger investments than many of our competitors. We believe that the ability to underwrite, syndicate and hold larger investments benefits our stockholders by (a) potentially increasing net income and earnings through syndication, (b) increasing originated deal flow flexibility, (c) broadening market relationships and deal flow, (d) allowing us to optimize our portfolio composition and (e) allowing us to provide capital to middle-market companies, which we believe currently have limited access to capital from traditional lending sources. In addition, we believe that the ability to provide capital at every level of the balance sheet provides a strong value proposition to middle-market borrowers and our senior debt capabilities provide superior deal origination and relative value analysis capabilities compared to traditional "mezzanine only" lenders.

Broad Origination Strategy

        We focus on self-originating most of our investments by pursuing a broad array of investment opportunities in middle-market companies across multiple channels. We also leverage off of the extensive relationships of the broader Ares platform, including relationships with the portfolio companies in the IHAM vehicles, to identify investment opportunities. We believe that this allows for asset selectivity and that there is a significant relationship between proprietary deal origination and credit performance. We believe that our focus on generating proprietary deal flow and lead investing also gives us greater control over capital structure, deal terms, pricing and documentation and enables us to actively manage our portfolio investments. Moreover, by leading the investment process, we are often able to secure controlling positions in credit tranches, thereby providing additional control in investment outcomes. We also have originated substantial proprietary deal flow from middle-market intermediaries, which often allows us to act as the sole or principal source of institutional capital to the borrower.

OPERATING AND REGULATORY STRUCTURE

        Our investment activities are managed by Ares Capital Management, which is wholly owned by Ares, and supervised by our board of directors, a majority of whom are independent of Ares and its affiliates. Ares Capital Management is registered under the Investment Advisers Act of 1940, or the "Advisers Act." Under our amended and restated investment advisory and management agreement with Ares Capital Management, referred to herein as our "investment advisory and management agreement," we have agreed to pay Ares Capital Management an annual base management fee based on our total assets, as defined under the Investment Company Act (other than cash and cash

7

---

equivalents, but including assets purchased with borrowed funds), and an incentive fee based on our performance.

        As a BDC, we are required to comply with certain regulatory requirements. For example, we are not generally permitted to invest in any portfolio company in which funds managed by Ares or any of its downstream affiliates (including Ares Capital Management) (other than Ares Capital and its downstream affiliates) currently has an investment (although we may co-invest on a concurrent basis with funds managed by Ares or any of its downstream affiliates (including Ares Capital Management), subject to compliance with existing regulatory guidance, applicable regulations and our allocation procedures). Some of these co-investments would only be permitted pursuant to an exemptive order from the SEC. We have applied for an exemptive order from the SEC that would permit us to co-invest with funds managed by Ares or its downstream affiliates (including Ares Capital Management). Any such order will be subject to certain terms and conditions. There is no assurance that the application for exemptive relief will be granted by the SEC. Accordingly, we cannot assure you that we will be permitted to co-invest with funds managed by Ares or any of its downstream affiliates (including Ares Capital Management). See "Risk Factors—Risks Relating to Our Business—We may not replicate Ares' historical success and our ability to enter into transactions with Ares and our other affiliates is restricted."

        Also, while we may borrow funds to make investments, our ability to use debt is limited in certain significant respects. As a BDC and a regulated investment company ("RIC") for tax purposes, we are dependent on our ability to raise capital through the issuance of common stock. RICs generally must distribute substantially all of their earnings to stockholders as dividends in order to preserve their status as a RIC and avoid corporate-level U.S. income tax. This requirement, in turn, generally prevents us from using earnings to support our operations including making new investments. Further, BDCs must have at least 200% asset coverage in order to incur debt or issue preferred stock (which we refer to collectively as "senior securities"), which requires us to finance our investments with at least as much equity as senior securities in the aggregate. Our Facilities (as defined herein) also require that we maintain asset coverage of 200%.

MARKET CONDITIONS

        Due to the volatility in global markets, the availability of capital and access to capital markets has been limited over the last several years. As the global liquidity situation and market conditions evolve, we will continue to monitor and adjust our approach to funding accordingly. However, given the unprecedented nature of the recent volatility in the global markets and the uncertainty around the strength of the U. S. economic recovery, there can be no assurances that these activities will be successful. While levels of market disruption and volatility have improved, there can be no assurance that adverse market conditions will not repeat themselves. If they do, we could face materially higher financing costs. Consequently, our operating strategy could be materially and adversely affected. See "Risk Factors—Risks Relating to Our Business—Capital markets have recently been in a period of disruption and instability. These market conditions materially and adversely affected debt and equity capital markets in the United States, which had, and may in the future continue to have, a negative impact on our business and operations."

        In connection with the prior depressed market conditions of the general economy, the stocks of BDCs as an industry have in the past traded at near historic lows as a result of concerns over liquidity, credit quality, leverage restrictions and distribution requirements. In some cases, certain BDCs became "forced sellers" of assets, defaulted on their indebtedness, decreased their distributions to stockholders or announced share repurchase programs. We cannot assure you that the market pressures we face will not have a material adverse effect on our business, financial condition and results of operations.

ARES CAPITAL CORPORATION PORTFOLIO

General

        We have built an investment portfolio of primarily first and second lien loans, mezzanine debt and, to a lesser extent, equity investments in private middle-market companies. Our portfolio is well diversified by industry sector and its concentration to any single issuer is limited. The SSLP consists of a diverse portfolio of loans to 32 different borrowers as of December 31, 2011 and the portfolio companies in the SSLP are in industries similar to the companies in Ares Capital's portfolio. Our investments have generally ranged between $20 million to $250 million each, although the investment size may be more or less than this range depending on capital availability. To a lesser extent, we also make preferred and/or common equity investments, which have generally been non-control equity investments of less than $20 million (usually in conjunction with a concurrent debt investment). However, we may increase the size or change the nature of these investments. Also, as a result of the Allied Acquisition, Allied Capital's equity investments, which included equity investments larger than those we have historically made and controlled portfolio company equity investments, became part of our portfolio. We intend to continue actively seeking opportunities over time to dispose of certain of the assets that were acquired in the Allied Acquisition, particularly non-yielding equity investments and these controlled portfolio company equity investments, as well as lower or non-yielding debt investments and investments that may not be core to our investment strategy, and generally rotate them into higher-yielding first and second lien senior loans and mezzanine debt investments. However, there can be no assurance that this strategy will be successful. See "Management's Discussion and Analysis of Financial Condition and Results of Operations- Portfolio and Investment Activity" for further information on the rotation of investments acquired as part of the Allied Acquisition.

        In addition, the proportion of these types of investments will change over time given our views on, among other things, the economic and credit environment we are operating in. In connection with our investing activities, we may make commitments with respect to indebtedness or securities of a potential portfolio company substantially in excess of our final investment. In such situations, while we may initially agree to fund up to a certain dollar amount of an investment, we may subsequently syndicate a portion of such amount to third parties such that we are left with a smaller investment than what was reflected in our original commitment. In addition to originating investments, we may also acquire investments in the secondary market.

        We make senior secured loans primarily in the form of first and/or second lien loans. Our first and second lien loans generally have terms of three to 10 years. Such first and second lien loans are granted a security interest in certain of the assets of the borrower and consequently such assets serve as collateral in support of the repayment of such senior secured loans. Senior secured loans are generally exposed to the least amount of credit risk because they typically hold a senior position with respect to scheduled interest and principal payments and security interests in assets of the borrower. However, unlike mezzanine debt, senior secured loans typically do not receive any stock, warrants to purchase stock or other yield enhancements. Senior secured loans may include revolving lines of credit, senior term loans, senior syndicated loans and senior last-out tranche loans.

        Structurally, mezzanine debt usually ranks subordinate in priority of payment to senior loans and is often unsecured. However, mezzanine debt ranks senior to common and preferred equity in a borrowers' capital structure. Typically, mezzanine debt has elements of both debt and equity instruments, offering the fixed returns in the form of interest payments associated with senior loans, while providing lenders an opportunity to participate in the capital appreciation of a borrower, if any, through an equity interest. This equity interest typically takes the form of an equity co-investment and/or warrants. Due to its higher risk profile and often less restrictive covenants as compared to senior loans, mezzanine debt generally yields a higher return than senior secured debt. The equity co-investment and warrants associated with mezzanine debt typically allow lenders to receive repayment

of their principal on an agreed amortization schedule while retaining their equity interest in the borrower. Equity issued in connection with mezzanine debt also may include a "put" feature, which permits the holder to sell its equity interest back to the borrower at a price determined through an agreed formula.

        In making an equity investment, in addition to considering the factors discussed below under "—Investment Selection," we also consider the anticipated timing of a liquidity event, such as a public offering, sale of the company or redemption of our equity securities.

        Our principal focus is investing in first and second lien senior loans and mezzanine debt and, to a lesser extent, equity capital, of private middle-market companies in a variety of industries. We generally seek to invest in companies in the industries in which Ares' investment professionals have direct expertise. The following is a representative list of the industries in which we have invested:

•

Aerospace and Defense



•

Business Services



•

Consumer Products



•

Containers and Packaging



•

Education



•

Energy



•

Environmental Services



•

Financial Services



•

Food and Beverage



•

Healthcare Services



•

Investment Funds and Vehicles



•

Manufacturing



•

Other Services



•

Restaurant and Food Services



•

Retail



•

Telecommunications

        However, we may invest in other industries if we are presented with attractive opportunities.

        While our primary focus is to generate current income and capital appreciation through investments in first and second lien senior loans and mezzanine debt and, to a lesser extent, equity securities of eligible portfolio companies, we also may opportunistically invest up to 30% of our portfolio in non-qualifying assets, as permitted by the Investment Company Act. Specifically, as part of this 30% basket, we may invest in entities that are not considered "eligible portfolio companies" (as defined in the Investment Company Act), including companies outside of the United States, entities that are operating pursuant to certain exceptions to the Investment Company Act, and publicly traded entities whose public equity market capitalization exceeds the levels provided for in the Investment Company Act.

Managed Vehicles

        We have made investments in our portfolio company, IHAM, which manages ten unconsolidated credit vehicles: Ivy Hill Middle Market Credit Fund, Ltd. ("Ivy Hill I"), Ivy Hill Middle Market Credit Fund II, Ltd. ("Ivy Hill II"), Ivy Hill Middle Market Credit Fund III, Ltd. ("Ivy Hill III"), Ivy Hill Senior Debt Fund, L.P. and related vehicles ("Ivy Hill SDF" and, together with Ivy Hill I, Ivy Hill II and Ivy Hill III, the "Ivy Hill Funds"), Knightsbridge CLO 2007-1 Limited, Emporia Preferred Funding I, Ltd., Emporia Preferred Funding II, Ltd. and Emporia Preferred Funding III, Ltd. (collectively, the "Emporia Funds") and Ares Private Debt Strategies Fund II, L.P. and Ares Private Debt Strategies Fund III, L.P. (collectively, the "PDS Funds"). In addition, IHAM serves as the sub-adviser/sub-manager for four others: CoLTS 2005-1 Ltd., CoLTS 2005-2 Ltd. and CoLTS 2007-1 Ltd. (collectively, the "CoLTS Funds") and FirstLight Funding I, Ltd. ("FirstLight"). As of December 31, 2011, IHAM had total committed capital under management of approximately $3.4 billion, which included approximately $0.3 billion invested by Ares Capital in IHAM or securities issued by the IHAM Vehicles.

        IHAM or certain IHAM Vehicles have purchased investments from us for a purchase price equal to the fair value of such investments at the time of such purchases, including approximately $261 million, $113 million and $46 million for the years ending December 31, 2011, 2010 and 2009, respectively.

        IHAM is party to a separate administration agreement, referred to herein as the "IHAM administration agreement," with our administrator, Ares Operations. Pursuant to the IHAM administration agreement, our administrator provides IHAM with office facilities, equipment, clerical, bookkeeping and record keeping services, and the services of certain personnel to perform research and related services, services of, and oversight of, custodians, depositories, accountants, attorneys, underwriters and such other persons in any other capacity deemed to be necessary. Under the IHAM administration agreement, IHAM reimburses our administrator for all of the actual costs associated with such services, including its allocable portion of our administrator's overhead and the cost of our administrator's officers and respective staff in performing its obligations under the IHAM administration agreement.

        We also manage the AGILE Fund, an unconsolidated fund that had approximately $62 million of total committed capital under management as of December 31, 2011. At December 31, 2011 our investment in the AGILE Fund was $0.1 million at fair value, including unrealized depreciation of $0.1 million.

ALLIED ACQUISITION

        On October 26, 2009, we entered into a definitive agreement to acquire Allied Capital in an all stock transaction. On April 1, 2010, we completed the Allied Acquisition by acquiring the outstanding shares of Allied Capital in exchange for shares of our common stock in a transaction valued at approximately $908 million as of the closing date. Concurrently with the completion of the Allied

12

---

Acquisition, we repaid in full the $137 million of remaining principal amounts outstanding on Allied Capital's $250 million senior secured term loan. We also assumed all of Allied Capital's other outstanding debt obligations, including approximately $745 million in aggregate principal amount outstanding of Allied Capital's unsecured notes.

        Under the terms of the Allied Acquisition, each Allied Capital stockholder received 0.325 shares of our common stock for each share of Allied Capital common stock then owned by such stockholder. In connection with the Allied Acquisition, approximately 58.5 million shares of our common stock (including the effect of outstanding in-the money Allied Capital stock options) were issued to Allied Capital's then-existing stockholders, resulting in our then-existing stockholders owning approximately 69% of the combined company and the then-existing Allied Capital stockholders owning approximately 31% of the combined company.

        The Allied Acquisition was accounted for in accordance with the acquisition method of accounting as detailed in Accounting Standards Codification ("ASC") 805-10 (previously Statement of Financial Accounting Standards ("SFAS") No. 141(R)), Business Combinations). The acquisition method of accounting requires an acquirer to recognize the assets acquired, the liabilities assumed and any noncontrolling interest in the acquired entity based on their fair values as of the date of acquisition. As described in more detail in ASC 805-10, if the total acquisition date fair value of the identifiable net assets acquired exceeds the fair value of the consideration transferred, the excess will be recognized as a gain. Upon completion of our determination of the fair value of Allied Capital's identifiable net assets as of April 1, 2010, the fair value of such net assets exceeded the fair value of the consideration transferred, resulting in the recognition of a gain. The valuation of the investments acquired as part of the Allied Acquisition was done in accordance with Ares Capital's valuation policy.

        Set forth below is the allocation of the purchase price to the assets acquired and liabilities assumed in connection with the Allied Acquisition:

        Prior to the completion of the Allied Acquisition we purchased $340 million of assets from Allied Capital in arm's length transactions. Additionally, during the same period of time, IHAM purchased $69 million of assets from Allied Capital, also in arm's length transactions.

        We intend to continue actively seeking opportunities over time to dispose of certain of the assets that were acquired in the Allied Acquisition, particularly non-yielding equity investments, as well as

13

lower or non-yielding debt investments and investments that may not be core to our investment strategy, and generally rotate them into higher-yielding first and second lien senior loans and mezzanine debt investments. However, there can be no assurance that this strategy will be successful. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Portfolio and Investment Activity" for further information on the rotation of investments acquired as part of the Allied Acquisition.

INVESTMENT SELECTION

        Ares' investment philosophy was developed over the past 22 years and has remained consistent and relevant throughout a number of economic cycles. We are managed using a similar investment philosophy used by the investment professionals of Ares in Ares' private investment funds.

        This investment philosophy involves, among other things:

•

an assessment of the overall macroeconomic environment and financial markets and how such assessment may impact industry and asset selection;



•

company-specific research and analysis; and



•

with respect to each individual company, an emphasis on capital preservation, low volatility and minimization of downside risk.

        The foundation of Ares' investment philosophy is intensive credit investment analysis, a portfolio management discipline based on both market technicals and fundamental value-oriented research, and diversification strategy. We follow a rigorous investment process based on:

•

a comprehensive analysis of issuer creditworthiness, including a quantitative and qualitative assessment of the issuer's business;



•

an evaluation of management and its economic incentives;



•

an analysis of business strategy and industry trends; and



•

an in-depth examination of capital structure, financial results and projections.

        We seek to identify those companies exhibiting superior fundamental risk-reward profiles and strong defensible business franchises while focusing on the relative value of the investment across the industry as well as for the specific company.

Intensive Due Diligence

        The process through which an investment decision is made involves extensive research into the target company, its industry, its growth prospects and its ability to withstand adverse conditions. If the senior investment professional responsible for the transaction determines that an investment opportunity should be pursued, we will engage in an intensive due diligence process. Approximately 30-40% of the investments initially reviewed by us proceed to this phase. Though each transaction will involve a somewhat different approach, the regular due diligence steps generally undertaken include:

•

meeting with the target company's management to get an insider's view of the business, and to probe for potential weaknesses in business prospects;



•

checking management's backgrounds and references;



•

performing a detailed review of historical financial performance, including performance through various economic cycles, and the quality of earnings;



•

visiting headquarters and company operations and meeting with top and middle-level executives;

14

---

•

contacting customers and vendors to assess both business prospects and standard practices;



•

conducting a competitive analysis, and comparing the issuer to its main competitors on an operating, financial, market share and valuation basis;



•

researching the industry for historic growth trends and future prospects as well as to identify future exit alternatives (including available Wall Street research, industry association literature and general news);



•

assessing asset value and the ability of physical infrastructure and information systems to handle anticipated growth; and



•

investigating legal risks and financial and accounting systems.

Selective Investment Process

        After an investment has been identified and preliminary diligence has been completed, a credit research and analysis report is prepared. This report is reviewed by the senior investment professional in charge of the potential investment. If such senior and other investment professionals are in favor of the potential investment, then it is first presented to an underwriting committee, which is comprised of the senior partners of the Ares Private Debt Group. The investment professionals of Ares Capital Management are responsible for the day-to-day management of our portfolio.

        After the investment is approved by the underwriting committee, a more extensive due diligence process is employed by the transaction team. Additional due diligence with respect to any investment may be conducted on our behalf by attorneys, independent accountants, and other third party consultants and research firms prior to the closing of the investment, as appropriate on a case-by-case basis. Approximately 7-10% of all investments initially reviewed by us will be presented to the investment committee. Approval of an investment for funding requires the approval of the majority of the investment committee of Ares Capital Management, although unanimous consent is sought.

Issuance of Formal Commitment

        Once we have determined that a prospective portfolio company is suitable for investment, we work with the management and/or sponsor of that company and its other capital providers, including senior, junior and equity capital providers, if any, to finalize the structure of the investment. Approximately 5-7% of the investments initially reviewed by us eventually result in the issuance of formal commitments.

Debt Investments

        We invest in portfolio companies primarily in the form of first and second lien senior loans and mezzanine debt. The first and second lien senior loans generally have terms of three to seven years. Such first and second lien senior loans have security interests in the assets of our portfolio companies that will serve as collateral in support of the repayment of such loans. First and second lien senior loans generally have floating interest rates, which may have LIBOR floors, and also may provide for some amortization of principal and excess cash flow payments, with the remaining principal balance due at maturity.

        We structure our mezzanine investments primarily as unsecured subordinated loans that provide for relatively high fixed interest rates that provide us with significant current interest income. The mezzanine debt investments generally have terms of up to 10 years. These loans typically have interest-only payments in the early years, with amortization of principal deferred to the later years of the mezzanine investment. In some cases, we may enter into loans that, by their terms, convert into equity or additional debt or defer payments of interest (or at least cash interest) for the first few years

15

---

after our investment. Also, in some cases our mezzanine debt will be secured by a subordinated lien on some or all of the assets of the borrower.

        In some cases, our debt investments may provide for a portion of the interest payable to be payment-in-kind ("PIK") interest. To the extent interest is PIK, it will be payable through the increase of the principal amount of the loan by the amount of interest due on the then-outstanding aggregate principal amount of such loan.

        In the case of our first and second lien senior loans and mezzanine debt, we tailor the terms of the investment to the facts and circumstances of the transaction and the prospective portfolio company, negotiating a structure that aims to protect our rights and manage our risk while creating incentives for the portfolio company to achieve its business plan and improve its profitability. For example, in addition to seeking a senior position in the capital structure of our portfolio companies, we will seek, where appropriate, to limit the downside potential of our investments by:

•

targeting a total return on our investments (including both interest and potential equity appreciation) that compensates us for credit risk;



•

incorporating "put" rights, call protection and LIBOR floors for floating rate loans, into the investment structure; and



•

negotiating covenants in connection with our investments that afford our portfolio companies as much flexibility in managing their businesses as possible, consistent with preservation of our capital. Such restrictions may include affirmative and negative covenants, default penalties, lien protection, change of control provisions and board rights, including either observation or participation rights.

        We generally require financial covenants and terms that require an issuer to reduce leverage, thereby enhancing credit quality. These methods include: (a) maintenance leverage covenants requiring a decreasing ratio of indebtedness to cash flow over time, (b) maintenance cash flow covenants requiring an increasing ratio of cash flow to the sum of interest expense and capital expenditures and (c) indebtedness incurrence prohibitions, limiting a company's ability to take on additional indebtedness. In addition, by including limitations on asset sales and capital expenditures we may be able to prevent a company from changing the nature of its business or capitalization without our consent.

        Our debt investments may include equity features, such as warrants or options to buy a minority interest in the portfolio company. Warrants we receive with our debt investments may require only a nominal cost to exercise, and thus, as a portfolio company appreciates in value, we may achieve additional investment return from this equity interest. We may structure the warrants to provide provisions protecting our rights as a minority-interest holder, as well as puts, or rights to sell such securities back to the portfolio company, upon the occurrence of specified events. In many cases, we also obtain registration rights in connection with these equity interests, which may include demand and "piggyback" registration rights.

Equity Investments

        To a lesser extent, we also make preferred and/or common equity investments, which have generally been non-control equity investments of less than $20 million (usually in conjunction with a concurrent debt investment). However, we may increase the size or change the nature of these investments. Also, as a result of the Allied Acquisition, Allied Capital's equity investments, which included equity investments larger than those we have historically made and controlled portfolio company equity investments, became part of our portfolio. We intend to continue actively seeking opportunities over time to dispose of certain of the assets that were acquired in the Allied Acquisition, particularly non-yielding equity investments and these controlled portfolio company equity investments,

16

---

as well as lower or non-yielding debt investments and investments that may not be core to our investment strategy, and generally rotate them into higher-yielding first and second lien senior loans and mezzanine debt investments. However, there can be no assurance that this strategy will be successful. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Portfolio and Investment Activity" for further information on the rotation of investments acquired as part of the Allied Acquisition.

ON-GOING RELATIONSHIPS WITH AND MONITORING OF PORTFOLIO COMPANIES

        We closely monitor each investment we make, maintain a regular dialogue with both the management team and other stakeholders and seek specifically tailored financial reporting. In addition, senior investment professionals may take board seats or obtain board observation rights for our portfolio companies. As of December 31, 2011, of our 141 portfolio companies, we were entitled to board seats or board observation rights on 57% of these companies.

        We seek to exert significant influence post-investment, in addition to covenants and other contractual rights and through board participation, when appropriate, by actively working with management on strategic initiatives. We often introduce managers of companies in which we have invested to other portfolio companies to capitalize on complementary business activities and best practices.

        Our investment adviser employs an investment rating system to categorize our investments. In addition to various risk management and monitoring tools, our investment adviser grades the credit risk of all investments on a scale of 1 to 4 no less frequently than quarterly. This system is intended primarily to reflect the underlying risk of a portfolio investment relative to our initial cost basis in respect of such portfolio investment (i.e., at the time of acquisition), although it may also take into account under certain circumstances the performance of the portfolio company's business, the collateral coverage of the investment and other relevant factors. Under this system, investments with a grade of 4 involve the least amount of risk to our initial cost basis. The trends and risk factors for this investment since origination or acquisition are generally favorable, which may include the performance of the portfolio company or a potential exit. Investments graded 3 involve a level of risk to our initial cost basis that is similar to the risk to our initial cost basis at the time of origination or acquisition. This portfolio company is generally performing as expected and the risk factors to our ability to ultimately recoup the cost of our investment are neutral to favorable. All investments or acquired investments in new portfolio companies are initially assessed a grade of 3. Investments graded 2 indicate that the risk to our ability to recoup the initial cost basis of such investment has increased materially since origination or acquisition, including as a result of factors such as declining performance and non-compliance with debt covenants; however, payments are generally not more than 120 days past due. An investment grade of 1 indicates that the risk to our ability to recoup the initial cost basis of such investment has substantially increased since origination or acquisition, and the portfolio company likely has materially declining performance. For debt investments with an investment grade of 1, most or all of the debt covenants are out of compliance and payments are substantially delinquent. For investments graded 1, it is anticipated that we will not recoup our initial cost basis and may realize a substantial loss of our initial cost basis upon exit. For investments graded 1 or 2, our investment adviser enhances its level of scrutiny over the monitoring of such portfolio company. Our investment adviser grades the investments in our portfolio at least each quarter and it is possible that the grade of certain of these portfolio investments may be reduced or increased over time.

        As of December 31, 2011, the weighted average grade of our portfolio was 3.0. For more information, see "Management's Discussion and Analysis of Financial Condition and Results of Operations—Portfolio and Investment Activity."

MANAGERIAL ASSISTANCE

        As a BDC, we must offer, and must provide upon request, significant managerial assistance to certain of our portfolio companies. This assistance could involve, among other things, monitoring the operations of our portfolio companies, participating in board and management meetings, consulting with and advising officers of portfolio companies and providing other organizational and financial guidance. We may receive fees for these services.

COMPETITION

        Our primary competitors include public and private funds, commercial and investment banks, commercial financing companies, other BDCs and private equity funds, each of which we compete with for financing opportunities. Many of our competitors are substantially larger and have considerably greater financial and marketing resources than we do. For example, some competitors may have access to funding sources that are not available to us. In addition, some of our competitors may have higher risk tolerances or different risk assessments, which could allow them to consider a wider variety of investments and establish more relationships than Ares Capital. Furthermore, many of our competitors are not subject to the regulatory restrictions that the Investment Company Act imposes on us as a BDC. For additional information concerning the competitive risks we face, see "Risk Factors—Risks Relating to Our Business—We operate in a highly competitive market for investment opportunities."

        We believe that the relationships of the members of our investment adviser's investment committees and of the senior principals of Ares enable us to learn about, and compete effectively for, financing opportunities with attractive middle-market companies in the industries in which we seek to invest. We believe that Ares' professionals' deep and long-standing direct sponsor relationships and the resulting proprietary transaction opportunities that these relationships often present, provide valuable insight and access to transactions and information. We use the industry information of Ares' investment professionals to which we have access to assess investment risks and determine appropriate pricing for our investments in portfolio companies.

STAFFING

        We do not currently have any employees and do not expect to have any employees. Services necessary for our business are provided by individuals who are employees or affiliates of our investment adviser, Ares Capital Management, and our administrator, Ares Operations, each of which is a wholly owned subsidiary of Ares Management, pursuant to the terms of the investment advisory and management agreement and our amended and restated administration agreement with our administrator, referred to herein as our "administration agreement," respectively, each as described below. Each of our executive officers is an employee or affiliate of Ares Operations or Ares Capital Management. Our day-to-day investment activities are managed by our investment adviser. Most of the services necessary for the origination and administration of our investment portfolio are provided by investment professionals employed by Ares Capital Management. Ares Capital Management has approximately 70 investment professionals who focus on origination, transaction development, investment and the ongoing monitoring of our investments. We reimburse both Ares Capital Management and Ares Operations for a certain portion of expenses incurred in connection with such staffing, as described in more detail below. Because we have no employees, Ares Capital does not have a formal employee relations policy.

INVESTMENT ADVISORY AND MANAGEMENT AGREEMENT

Management Services

        Ares Capital Management serves as our investment adviser and is registered as an investment adviser under the Advisers Act. Subject to the overall supervision of our board of directors, our

18

---

investment adviser manages the day-to-day operations of, and provides investment advisory and management services to, Ares Capital. Under the terms of the investment advisory and management agreement, Ares Capital Management:

•

determines the composition of our portfolio, the nature and timing of the changes to our portfolio and the manner of implementing such changes;



•

identifies, evaluates and negotiates the structure of the investments we make (including performing due diligence on our prospective portfolio companies);



•

closes and monitors the investments we make;



•

determines the investments and other assets that we purchase, retain or sell; and



•

provides us with such other investment advisory and research and related services as we may from time to time reasonably require.

        Ares Capital Management's services to us under the investment advisory and management agreement are not exclusive, and it is free to furnish similar services to other entities. Similarly, affiliates of our investment adviser may directly or indirectly manage funds or other investment vehicles with investment objectives similar to ours. Accordingly, we may compete with these Ares funds or other investment vehicles managed by our investment adviser and its affiliates for capital and investment opportunities. Ares Capital Management endeavors to allocate investment opportunities in a fair and equitable manner, and in any event consistent with any fiduciary duties owed to Ares Capital. Nevertheless, it is possible that we may not be given the opportunity to participate in certain investments made by investment funds or other investment vehicles managed by Ares Capital Management or its affiliates.

        The sole member of Ares Capital Management is Ares Management, a global alternative asset manager and SEC registered investment adviser. Ares funds, including funds managed by Ares, had, as of December 31, 2011, approximately $46 billion of total committed capital under management.

Management Fee

        Pursuant to the investment advisory and management agreement and subject to the overall supervision of our board of directors, Ares Capital Management provides investment advisory and management services to us. For providing these services, Ares Capital Management receives a fee from us consisting of two components—a base management fee and an incentive fee.

        The base management fee is calculated at an annual rate of 1.5% based on the average value of our total assets (other than cash or cash equivalents but including assets purchased with borrowed funds) at the end of the two most recently completed calendar quarters. The base management fee is payable quarterly in arrears.

        The incentive fee has two parts. The first part is calculated and payable quarterly in arrears based on our pre-incentive fee net investment income for the quarter. Pre-incentive fee net investment income means interest income, dividend income and any other income (including any other fees such as commitment, origination, structuring, diligence and consulting fees or other fees that we receive from portfolio companies but excluding fees for providing managerial assistance) accrued during the calendar quarter, minus operating expenses for the quarter (including the base management fee, any expenses payable under the administration agreement, and any interest expense and dividends paid on any outstanding preferred stock, but excluding the incentive fee). Pre-incentive fee net investment income includes, in the case of investments with a deferred interest feature such as market discount, debt instruments with PIK interest, preferred stock with PIK dividends and zero coupon securities, accrued income that we have not yet received in cash. Our investment adviser is not under any obligation to

19

---

reimburse us for any part of the incentive fee it received that was based on accrued interest that we never actually receive.

        Pre-incentive fee net investment income does not include any realized capital gains, realized capital losses, unrealized capital appreciation, unrealized capital depreciation or income tax expense related to realized gains. Because of the structure of the incentive fee, it is possible that we may pay an incentive fee in a quarter where we incur a loss. For example, if we receive pre-incentive fee net investment income in excess of the hurdle rate (as defined below) for a quarter, we will pay the applicable incentive fee even if we have incurred a loss in that quarter due to realized and/or unrealized capital losses.

        Pre-incentive fee net investment income, expressed as a rate of return on the value of our net assets (defined as total assets less indebtedness and before taking into account any incentive fees payable during the period) at the end of the immediately preceding calendar quarter, is compared to a fixed "hurdle rate" of 1.75% per quarter. If market credit spreads rise, we may be able to invest our funds in debt instruments that provide for a higher return, which may increase our pre-incentive fee net investment income and make it easier for our investment adviser to surpass the fixed hurdle rate and receive an incentive fee based on such net investment income. To the extent we have retained pre-incentive fee net investment income that has been used to calculate this part of the incentive fee, it is also included in the amount of our total assets (other than cash and cash equivalents but including assets purchased with borrowed funds) used to calculate the 1.5% base management fee.

        We pay our investment adviser an incentive fee with respect to our pre-incentive fee net investment income in each calendar quarter as follows:

•

no incentive fee in any calendar quarter in which our pre-incentive fee net investment income does not exceed the hurdle rate;



•

100% of our pre-incentive fee net investment income with respect to that portion of such pre-incentive fee net investment income, if any, that exceeds the hurdle rate but is less than 2.1875% in any calendar quarter. We refer to this portion of our pre-incentive fee net investment income (which exceeds the hurdle rate but is less than 2.1875%) as the "catch-up" provision. The "catch-up" is meant to provide our investment adviser with 20% of the pre-incentive fee net investment income as if a hurdle rate did not apply if this net investment income exceeded 2.1875% in any calendar quarter; and



•

20% of the amount of our pre-incentive fee net investment income, if any, that exceeds 2.1875% in any calendar quarter.

        These calculations are adjusted for any share issuances or repurchases during the quarter.

        The second part of the incentive fee (the "Capital Gains Fee"), is determined and payable in arrears as of the end of each calendar year (or, upon termination of the investment advisory and management agreement, as of the termination date) and is calculated at the end of each applicable year by subtracting (a) the sum of our cumulative aggregate realized capital losses and aggregate unrealized capital depreciation from (b) our cumulative aggregate realized capital gains, in each case calculated from October 8, 2004. Realized capital gains and losses include gains and losses on investments and foreign currencies, as well as gains and losses on extinguishment of debt and other assets. If such amount is positive at the end of such year, then the Capital Gains Fee for such year is equal to 20% of such amount, less the aggregate amount of Capital Gains Fees paid in all prior years. If such amount is negative, then there is no Capital Gains Fee for such year.

20

---

        The cumulative aggregate realized capital gains are calculated as the sum of the differences, if positive, between (a) the net sales price of each investment in our portfolio when sold and (b) the accreted or amortized cost basis of such investment.

        The cumulative aggregate realized capital losses are calculated as the sum of the amounts by which (a) the net sales price of each investment in our portfolio when sold is less than (b) the accreted or amortized cost basis of such investment.

        The aggregate unrealized capital depreciation is calculated as the sum of the differences, if negative, between (a) the valuation of each investment in our portfolio as of the applicable Capital Gains Fee calculation date and (b) the accreted or amortized cost basis of such investment.

        Notwithstanding the foregoing, as a result of an amendment to the capital gains portion of the incentive fee under the investment advisory and management agreement (the "Capital Gains Amendment") that was adopted by our stockholders on June 6, 2011, if we are required by Generally Accepted Accounting Principles ("GAAP") to record an investment at its fair value as of the time of acquisition instead of at the actual amount paid for such investment by us (including, for example, as a result of the application of the acquisition method of accounting), then solely for the purposes of calculating the Capital Gains Fee, the "accreted or amortized cost basis" of an investment shall be an amount (the "Contractual Cost Basis") equal to (1) (x) the actual amount paid by the Company for such investment plus (y) any amounts recorded in the Company's financial statements as required by GAAP that are attributable to the accretion of such investment plus (z) any other adjustments made to the cost basis included in the Company's financial statements, including PIK interest or additional amounts funded (net of repayments) minus (2) any amounts recorded in the Company's financial statements as required by GAAP that are attributable to the amortization of such investment, whether such calculated Contractual Cost Basis is higher or lower than the fair value of such investment (as determined in accordance with GAAP) at the time of acquisition.

        We defer cash payment of any incentive fee otherwise earned by our investment adviser if during the most recent four full calendar quarter period ending on or prior to the date such payment is to be made the sum of (a) the aggregate distributions to our stockholders and (b) the change in net assets (defined as total assets less indebtedness and before taking into account any incentive fees payable during the period) is less than 7.0% of our net assets (defined as total assets less indebtedness) at the beginning of such period. Any deferred incentive fees are carried over for payment in subsequent calculation periods to the extent such payment is payable under the investment advisory and management agreement.

Payment of Our Expenses

        The services of all investment professionals and staff of our investment adviser, when and to the extent engaged in providing investment advisory and management services to Ares Capital, and the compensation and routine overhead expenses of such personnel allocable to such services, are provided and paid for by Ares Capital Management. We bear all other costs and expenses of our operations and transactions, including those relating to: rent; organization; calculation of our net asset value (including the cost and expenses of any independent valuation firm); expenses incurred by Ares Capital Management payable to third parties, including agents, consultants or other advisers, in monitoring our financial and legal affairs and in monitoring our investments and performing due diligence on our prospective portfolio companies; interest payable on indebtedness, if any, incurred to finance our investments; offerings of our common stock and other securities; investment advisory and management fees; administration fees; fees payable to third parties, including agents, consultants or other advisers, relating to, or associated with, evaluating and making investments; transfer agent and custodial fees; registration fees; listing fees; taxes; independent directors' fees and expenses; costs of preparing and filing reports or other documents with the SEC; the costs of any reports, proxy statements or other

notices to stockholders, including printing costs; to the extent we are covered by any joint insurance policies, our allocable portion of the insurance premiums for such policies; direct costs and expenses of administration, including auditor and legal costs; and all other expenses incurred by us or Ares Operations in connection with administering our business as described in more detail under "Administration Agreement" below.

Duration, Termination and Amendment

        At an in-person meeting of our board of directors on March 16, 2011, the form of our current investment advisory and management agreement, including two proposed amendments to our then existing investment advisory and management agreement, was approved by our board of directors with the recommendation that stockholders of the Company vote to approve the proposed amendments. A discussion regarding the basis for our board of directors' approval is available in our proxy statement for our 2011 Annual Stockholders Meeting. On June 6, 2011, our stockholders approved the proposed amendments to our then existing investment advisory and management agreement. On June 6, 2011, the Company entered into our current investment advisory and management agreement, which implemented the following amendments approved by the Company's stockholders:

(i)

the quarterly income hurdle rate used in calculating the income portion of the incentive fee payable to the Company's investment adviser was lowered from 2.0% (or 8.0% annually) to 1.75% (or 7.0% annually), the related quarterly catch-up hurdle rate was adjusted from 2.5% to 2.1875% (or from 10.0% to 8.75% annually) and the general hurdle for deferral of payment of incentive fees generally was lowered from 8.0% over the prior four full calendar quarters to 7.0% over the prior four full calendar quarters; and



(ii)

the capital gains portion of the incentive fee is calculated using an actual purchase price paid by the Company as the "cost" of such asset even when GAAP requires the Company to record cost at fair value, whether such purchase price is higher or lower than the fair value of such asset at the time of acquisition.

        Unless terminated earlier, the investment advisory and management agreement will automatically renew for successive annual periods if approved annually by our board of directors or by the affirmative vote of the holders of a majority of our outstanding voting securities, including, in either case, approval by a majority of our directors who are not "interested persons" of the Company (as defined in the Investment Company Act).

        In voting to approve the current investment advisory and management agreement, the independent directors had the opportunity to consult in executive session with counsel to the Company regarding the approval of such agreement. In reaching a decision to approve the current investment advisory and management agreement, our board of directors reviewed a significant amount of information and considered, among other things:

(i)

the nature, extent and quality of the advisory and other services to be provided to the Company by our investment adviser;



(ii)

the long and short-term investment performance of the Company and our investment adviser;



(iii)

the costs of the services to be provided by our investment adviser (including management fees, advisory fees and expense ratios);



(iv)

the limited potential for economies of scale in investment management associated with a larger capital base for investments in first and second lien senior loans and mezzanine debt and whether such limited economies of scale would benefit our stockholders;



(v)

our investment adviser's estimated pro forma profitability with respect to managing us;

(vi)

the limited potential for our investment adviser and its affiliates to derive additional benefits as a result of our relationship with our investment adviser; and



(vii)

various other matters.

        In voting to approve the current investment advisory and management agreement, our board of directors, including all of the directors who are not "interested persons," of the Company, made the following conclusions:

•

Nature, Extent and Quality of Services.  Our board of directors considered the nature, extent and quality of the investment selection process employed by our investment adviser, including the flow of transaction opportunities resulting from Ares Capital Management's investment professionals' significant capital markets, trading and research expertise, the employment of Ares Capital Management's investment philosophy, diligence procedures, credit recommendation process, investment structuring, and ongoing relationships with and monitoring of portfolio companies, in light of the investment objective of the Company. Our board of directors also considered our investment adviser's personnel and their prior experience in connection with the types of investments made by us, including such personnel's network of relationships with intermediaries focused on middle-market companies. Our board of directors also considered the benefit and increasing costs of our investment adviser continuing to be able to recruit and retain top talent. In addition, our board of directors considered the other terms and conditions of the investment advisory and management agreement. Our board of directors concluded that the substantive terms of the investment advisory and management agreement (other than the fees payable thereunder, which our board of directors reviewed separately), including the services to be provided, are generally the same as those of comparable BDCs described in the available market data and that it would be difficult to obtain similar services on a comparable basis from other third party services providers or through an internally managed structure. In addition, our board of directors considered the fact that we have the ability to terminate the investment advisory and management agreement without penalty upon 60 days' written notice to our investment adviser. Our board of directors further concluded that our investment adviser is served by a dedicated origination, transaction development and investment team of investment professionals, and that these investment professionals have historically focused on investments in middle- market companies and have developed an investment evaluation process and an extensive network of relationships with financial sponsors and intermediaries focused on middle-market companies, which experience and relationships coincide with our investment objective and generally equal or exceed those of the management teams of other comparable BDCs described in the available market data.



•

Investment Performance.  Our board of directors reviewed the long-term and short-term investment performance of the Company and our investment adviser, as well as comparative data with respect to the long-term and short-term investment performance of other BDCs and their externally managed investment advisers. Our board of directors concluded that our investment adviser was delivering results consistent with the investment objective of the Company and that the Company's investment performance was generally above average when compared to comparable BDCs. Our board of directors further determined that in light of the performance history of the Company, our investment adviser's extensive experience with our particular investment objectives and policies and our investment adviser's commitment to the Company, the investment performance of the Company was likely to remain consistent with the approval of the investment advisory and management agreement.



•

Costs of the Services Provided to the Company.  Our board of directors considered comparative data based on publicly available information with respect to services rendered and the advisory fees (including the management fees and incentive fees) of other BDCs with similar investment

23

---

objectives, our operating expenses and expense ratios compared to other BDCs of similar size and with similar investment objectives, as well as the administrative services that our administrator will provide to us at cost. Based upon its review, our board of directors concluded that the fees to be paid under the investment advisory and management agreement are generally similar to those payable under agreements of comparable BDCs described in the available market data. In addition, after examining market data, information prepared by management and a detailed discussion with management, our board of directors determined that while our total expenses (adjusted for certain non-recurring items and including interest expense and credit facility fees) as a percentage of assets for the year ended December 31, 2010 were slightly above average as compared to those disclosed in market data by comparable BDCs, our total expenses (adjusted for certain non-recurring items and excluding interest expense and credit facility fees) as a percentage of assets for the year ended December 31, 2010 were similar to or lower than those disclosed by comparable BDCs. Our board of directors noted that the slightly above average total expenses as a percentage of assets were attributable to increased interest expense as a result of our strategy of decreasing our balance sheet risk by extending debt maturities and refinancing short-term borrowings under floating rate secured debt with long-term fixed rate unsecured debt. Our board of directors further noted that many of our BDC competitors have been unable to access such unsecured debt.

•

Economies of Scale.  Our board of directors considered information about the potential for our stockholders to experience economies of scale as the Company grows in size. Our board of directors considered that the private debt business is one of the least scalable businesses because it requires additional resources as it grows and also considered that because there are no break points in our investment adviser's fees, any benefits resulting from the growth in the Company's assets where the Company's fixed costs did not increase proportionately would not inure to the benefit of the stockholders. Therefore, the board determined that the advisory fee structure with respect to the investment advisory and management agreement was reasonable and that no changes were currently necessary to reflect economies of scale.



•

Estimated Pro Forma Profitability of the Investment Adviser.  Our board of directors considered information about our investment adviser's budget and determined that, based on the information available to our board of directors, our investment adviser's estimated pro forma profitability with respect to managing the Company was likely equal to or less than the profitability of investment advisers managing comparable BDCs though our board of directors noted that no market data was available for such advisers. Our board of directors noted that it was relying, in particular, on the fact that the management fee payable to our investment adviser is 1.50% (compared to 2.00% for several of the Company's competitors) and is not paid on cash or cash equivalents held by the Company (unlike some of the Company's competitors).



•

Limited Potential for Additional Benefits Derived by the Investment Adviser.  Our board of directors concluded that there is limited potential for additional benefits, such as soft dollar arrangements with brokers, to be derived by our investment adviser and its affiliates as a result of our relationship with our investment adviser.

        In view of the wide variety of factors that our board of directors considered in connection with its evaluation of the investment advisory and management agreement, it is not practical to quantify, rank or otherwise assign relative weights to the specific factors it considered in reaching its decision. Our board of directors did not undertake to make any specific determination as to whether any particular factor, or any aspect of any particular factor, was favorable or unfavorable to the ultimate determination of our board of directors. Rather, our board of directors based its approval on the totality of information presented to, and the investigation conducted by, it. In considering the factors discussed above, individual directors may have given different weights to different factors.

24

---

        Based on the information reviewed and the factors discussed above, our directors (including those directors who are not "interested persons" of the Company) concluded that the terms of the investment advisory and management agreement, including the fee rates thereunder, are fair and reasonable in relation to the services provided and approved the continuation of the investment advisory and management agreement with our investment adviser as being in the best interests of the Company and its stockholders.

        The investment advisory and management agreement will automatically terminate in the event of its assignment. The investment advisory and management agreement may be terminated by either party without penalty upon 60 days' written notice to the other party.

        Conflicts of interest may arise if our investment adviser seeks to change the terms of our investment advisory and management agreement, including, for example, the amount of the management fee, the incentive fee or other compensation terms. Any material change to the investment advisory and management agreement must be submitted to stockholders for approval under the Investment Company Act and we may from time to time decide it is appropriate to seek stockholder approval to change the terms of the agreement. See "Risk Factors—Risks Relating to our Business—We are dependent upon certain key personnel of Ares for our future success and upon their access to other Ares investment professionals."

Indemnification

        The investment advisory and management agreement provides that, absent willful misfeasance, bad faith or gross negligence in the performance of its duties or by reason of the reckless disregard of its duties and obligations, Ares Capital Management, its members and their respective officers, managers, partners, agents, employees, controlling persons and members and any other person or entity affiliated with it are entitled to indemnification from us for any damages, liabilities, costs and expenses (including reasonable attorneys' fees and amounts reasonably paid in settlement) arising from the rendering of Ares Capital Management's services under the investment advisory and management agreement or otherwise as our investment adviser.

Organization of the Investment Adviser

        Ares Capital Management is a Delaware limited liability company that is registered as an investment adviser under the Advisers Act. The principal executive offices of Ares Capital Management are located at 2000 Avenue of the Stars, 12th Floor, Los Angeles, California 90067.

ADMINISTRATION AGREEMENT

        We are also party to a separate administration agreement with Ares Operations, an affiliate of our investment adviser and a wholly owned subsidiary of Ares Management. Our board of directors approved the continuation of our administration agreement on March 16, 2011, which extended the term of the agreement until June 1, 2011. Pursuant to the administration agreement, Ares Operations furnishes us with office equipment and clerical, bookkeeping and record keeping services at our office facilities. Under the administration agreement, Ares Operations also performs, or oversees the performance of, our required administrative services, which include, among other things, providing assistance in accounting, legal, compliance, operations, technology, and investor relations, being responsible for the financial records that we are required to maintain and preparing reports to our stockholders and reports filed with the SEC. In addition, Ares Operations assists us in determining and publishing our net asset value, oversees the preparation and filing of our tax returns and the printing and dissemination of reports to our stockholders, and generally oversees the payment of our expenses and the performance of administrative and professional services rendered to us by others. Payments under the administration agreement are equal to an amount based upon our allocable portion of Ares

25

---

Operations' overhead and other expenses (including travel expenses) incurred by Ares Operations in performing its obligations under the administration agreement, including our allocable portion of the compensation of certain of our officers (including our chief compliance officer, chief financial officer, general counsel, treasurer and assistant treasurer) and their respective staffs.

Indemnification

        The administration agreement provides that, absent willful misfeasance, bad faith or negligence in the performance of its duties or by reason of the reckless disregard of its duties and obligations, Ares Operations, its members and their respective officers, managers, partners, agents, employees, controlling persons and members and any other person or entity affiliated with it are entitled to indemnification from us for any damages, liabilities, costs and expenses (including reasonable attorneys' fees and amounts reasonably paid in settlement) arising from the rendering of Ares Operations' services under the administration agreement or otherwise as our administrator.

LEVERAGE

        We borrow funds to make additional investments, a practice known as "leverage," to attempt to increase return to our common stockholders. With certain limited exceptions, we are only allowed to borrow amounts such that our asset coverage, as defined in the Investment Company Act, equals at least 200% after such borrowing. The amount of leverage that we employ at any particular time will depend on our investment adviser's and our board of directors' assessments of market and other factors at the time of any proposed borrowing. As of February 24, 2012, we had $1.9 billion of total principal debt outstanding under the various debt instruments described below. See "Risk Factors—Risks Relating to Our Business—We borrow money, which magnifies the potential for gain or loss on amounts invested and may increase the risk of investing with us."

        We may from time to time seek to retire or repurchase our common stock through cash purchases, as well as retire, cancel or purchase our outstanding debt through cash purchases and/or exchanges, in open market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will depend on prevailing market conditions, our liquidity requirements, contractual and regulatory restrictions and other factors. The amounts involved may be material.

        We are party to a revolving credit facility that currently provides for up to $810 million of borrowings (the "Revolving Credit Facility"). The Revolving Credit Facility also includes an "accordion" feature that allows us, under certain circumstances, to increase the size of the facility to a maximum of $1.05 billion. The Revolving Credit Facility matures on January 22, 2013. Subject to certain exceptions, the interest rate charged on the Revolving Credit Facility is based on LIBOR plus an applicable spread of between 2.50% and 4.00% or on the "alternate base rate" plus an applicable spread of between 1.50% and 3.00%, in each case, based on a pricing grid depending upon our credit rating. The current effective LIBOR spread under the Revolving Credit Facility is 3.00% (with no floor).

        Our wholly owned subsidiary Ares Capital CP Funding LLC ("Ares Capital CP") is party to a revolving funding facility, which, as amended, currently provides for up to $500 million of borrowings (the "Revolving Funding Facility"). The Revolving Funding Facility provides for a three-year reinvestment period until January 18, 2015 (with a one-year extension option, subject to our and the lenders' consent) and has a stated maturity of January 18, 2017 (with a one-year extension option, subject to our and the lenders' consent). Subject to certain exceptions, the interest rate charged on the Revolving Funding Facility is based on LIBOR plus 2.50% (with no floor). See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Recent Developments" and Note 19 to our consolidated financial statements for the year ended December 31, 2011 for information on recent amendments to the Revolving Funding Facility.

        In addition, in January 2012, our wholly owned subsidiary, Ares Capital JB Funding LLC ("ACJB LLC"), entered into an agreement for a revolving funding facility with Sumitomo Mitsui Banking Corporation ("SMBC") pursuant to which SMBC agreed to extend credit of up to $200 million at any one time outstanding (the "SMBC Funding Facility" and together with the Revolving Credit Facility and the Revolving Funding Facility, the "Facilities"). The SMBC Funding Facility provides for a three-year reinvestment period until January 20, 2015 (with two one-year extension options, subject to our and the lenders' consent) and has a stated maturity of January 20, 2020 (with two one-year extension options, subject to our and the lenders' consent). Subject to certain exceptions, the interest rate charged on the SMBC Funding Facility is based on LIBOR plus 2.125% (with no floor) or a "base rate" (which is the greater of a prime rate and the federal funds rate plus 0.50%) plus 1.125% (with no floor). See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Recent Developments" and Note 19 to our consolidated financial statements for the year ended December 31, 2011 for information on the SMBC Funding Facility.

        Through our wholly owned subsidiary ARCC CLO 2006 LLC ("ARCC CLO") we completed a $400.0 million debt securitization referred to herein as the "Debt Securitization" and issued approximately $314.0 million aggregate principal amount of asset-backed notes, which we refer to as the "CLO Notes," to third parties that are secured by a pool of middle-market loans that were purchased or originated by the Company. We retained approximately $86.0 million of certain "BBB" and non-rated securities in the Debt Securitization and had repurchased $34.8 million of various tranches of the CLO Notes as of December 31, 2011. The reinvestment period for the CLO Notes ended on June 17, 2011. The CLO Notes mature on December 20, 2019. As of December 31, 2011, the current blended interest rate charged on the CLO Notes, excluding fees, is approximately LIBOR plus 0.45% (with no floor).

        As part of the Allied Acquisition, the Company assumed $230.0 million principal amount outstanding of unsecured 6.875% Notes due on April 15, 2047 (the "2047 Notes"). In October 2010, we issued $200.0 million aggregate principal amount of unsecured 7.75% senior notes that mature on October 15, 2040 (the "2040 Notes"). In February 2012, we issued $143.8 million aggregate principal amount of unsecured 7.00% senior notes that mature on February 15, 2022 (the "2022 Notes", and together with the 2047 Notes and the 2040 Notes, the "Unsecured Notes"). The Unsecured Notes are listed on the New York Stock Exchange.

        In January 2011, we issued $575.0 million aggregate principal amount of convertible senior unsecured notes that mature on February 1, 2016 (the "February 2016 Convertible Notes"). Additionally, in March 2011, we issued $230.0 million aggregate principal amount of convertible senior unsecured notes that mature on June 1, 2016 (the "June 2016 Convertible Notes", and together with the February 2016 Convertible Notes, the "Convertible Notes"). The February 2016 Convertible Notes and the June 2016 Convertible Notes bear interest at a rate of 5.75% and 5.125%, respectively.

        We intend to continue borrowing under the Facilities in the future, either secured or unsecured, and we may increase the size of the Facilities or otherwise issue additional debt securities or other evidences of indebtedness in the future.

        For more information on the Company's debt, see "Management's Discussion and Analysis of Financial Condition and Results of Operations—Financial Condition, Liquidity and Capital Resources."

REGULATION

        We have elected to be regulated as a BDC under the Investment Company Act and have elected to be treated as a RIC under Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code"). As with other companies regulated by the Investment Company Act, a BDC must adhere to certain substantive regulatory requirements. The Investment Company Act contains prohibitions and

27

---

restrictions relating to transactions between BDCs and their affiliates (including any investment advisers or sub-advisers), principal underwriters and certain affiliates of those affiliates or underwriters. Among other things, we generally cannot invest in any portfolio company in which funds managed by Ares or any of its downstream affiliates (including Ares Capital Management) (other than Ares Capital and its downstream affiliates) currently has an investment (although we may co-invest on a concurrent basis with other funds managed by Ares or any of its downstream affiliates (including Ares Capital Management), subject to compliance with existing regulatory guidance, applicable regulations and our allocation procedures). Some of these co-investments would only be permitted pursuant to an exemptive order from the SEC. We have applied for an exemptive order from the SEC that would permit us to co-invest with funds managed by Ares or its downstream affiliates (including Ares Capital Management). Any such order will be subject to certain terms and conditions. There is no assurance that the application for exemptive relief will be granted by the SEC. Accordingly, we cannot assure you that we will be permitted to co-invest with funds managed by Ares or any of its downstream affiliates (including Ares Capital Management). See "Risk Factors—Risks Relating to Our Business—We may not replicate Ares' historical success and our ability to enter into transactions with Ares and our other affiliates is restricted."

        The Investment Company Act also requires that a majority of our directors be persons other than "interested persons," as that term is defined in the Investment Company Act. In addition, the Investment Company Act provides that we may not change the nature of our business so as to cease to be, or to withdraw our election as, a BDC unless that change is approved by holders of at least a majority of our outstanding voting securities. Under the Investment Company Act, the vote of holders of at least a majority of outstanding voting securities means the vote of the holders of the lesser of: (a) 67% or more of the outstanding shares of our common stock present at a meeting or represented by proxy if holders of more than 50% of the shares of our common stock are present or represented by proxy or (b) more than 50% of the outstanding shares of our common stock.

        We may invest up to 100% of our assets in securities acquired directly from issuers in privately negotiated transactions. With respect to such securities, we may, for the purpose of public resale, be deemed an "underwriter" as that term is defined in the Securities Act of 1933 (the "Securities Act"). Our intention is to not write (sell) or buy put or call options to manage risks associated with the publicly traded securities of our portfolio companies. We may enter into hedging transactions to manage the risks associated with interest rate and currency fluctuations. We may purchase or otherwise receive warrants or options to purchase the common stock of our portfolio companies in connection with acquisition financings or other investments. In connection with such an acquisition, we may acquire rights to require the issuers of acquired securities or their affiliates to repurchase them under certain circumstances.

        We also do not intend to acquire securities issued by any investment company that exceed the limits imposed by the Investment Company Act. Under these limits, we generally cannot acquire more than 3% of the voting stock of any investment company (as defined in the Investment Company Act), invest more than 5% of the value of our total assets in the securities of one investment company or invest more than 10% of the value of our total assets in the securities of investment companies in the aggregate. With regard to that portion of our portfolio invested in securities issued by investment companies, it should be noted that such investments might subject our stockholders to additional expenses.

PRIVACY PRINCIPLES

        We are committed to maintaining the privacy of our stockholders and to safeguarding their non-public personal information. The following information is provided to help you understand what personal information we collect, how we protect that information and why, in certain cases, we may share information with select other parties.

28

---

        Generally, we do not receive any non-public personal information relating to our stockholders, although certain non-public personal information of our stockholders may become available to us. The non-public personal information that we may receive falls into the following categories:

•

information we receive from stockholders, whether we receive it orally, in writing or electronically. This includes stockholders' communications to us concerning their investment;



•

information about stockholders' transactions and history with us; or



•

other general information that we may obtain about stockholders, such as demographic and contact information such as a person's address.

        We do not disclose any non-public personal information about our stockholders or former stockholders to anyone, except:

•

to our affiliates (such as our investment adviser and administrator) and their employees that have a legitimate business need for the information;



•

to our service providers (such as our accountants, attorneys, custodians, transfer agent, underwriters and proxy solicitors) and their employees, as is necessary to service recordholder accounts or otherwise provide the applicable services;



•

to comply with court orders, subpoenas, lawful discovery requests or other legal or regulatory requirements; or



•

as allowed or required by applicable law or regulation.

        When the Company shares non-public stockholder personal information referred to above, the information is made available for limited business purposes and under controlled circumstances designed to protect our stockholders' privacy. The Company does not permit use of stockholder information for any non-business or marketing purpose, nor does the Company permit third parties to rent, sell, trade or otherwise release or disclose information to any other party.

        The Company's service providers, such as its investment adviser, administrator and transfer agent, are required to maintain physical, electronic, and procedural safeguards to protect stockholder non-public personal information to prevent unauthorized access or use and to dispose of such information when it is no longer required.

        Personnel of our affiliates may access stockholder information only for business purposes. The degree of access is based on the sensitivity of the information and on personnel need for the information to service a stockholder's account or comply with legal requirements.

        If a stockholder ceases to be a stockholder, we will adhere to the privacy policies and practices as described above. We may choose to modify our privacy policies at any time. Before we do so, we will notify stockholders and provide a description of our privacy policy.

        In the event of a corporate change in control resulting from, for example, a sale to, or merger with, another entity, or in the event of a sale of assets, we reserve the right to transfer stockholders' non-public personal information to the new party in control or the party acquiring assets.

Item 1A.    Risk Factors

RISK FACTORS

        You should carefully consider these risk factors, together with all of the other information included in this Annual Report, including our consolidated financial statements and the related notes thereto, before you decide whether to make an investment in our securities. The risks set out below are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results. If any of the following events occur, our business, financial condition and results of operations could be materially adversely affected. In such case, the net asset value of our common stock and the trading price of our securities could decline, and you may lose all or part of your investment.

RISKS RELATING TO OUR BUSINESS

Capital markets have recently been in a period of disruption and instability. These market conditions materially and adversely affected debt and equity capital markets in the United States, which had, and may in the future continue to have, a negative impact on our business and operations.

        Beginning in 2007, the U.S. capital markets entered into a period of disruption as evidenced by a lack of liquidity in the debt capital markets, significant write-offs in the financial services sector, the re-pricing of credit risk in the broadly syndicated credit market and the failure of major financial institutions. Despite actions of the U.S. federal government, these events contributed to worsening general economic conditions that materially and adversely impacted the broader financial and credit markets and reduced the availability of debt and equity capital for the market as a whole and financial services firms in particular. While market conditions have improved from the beginning of the disruption, there have been recent periods of volatility and there can be no assurance that adverse market conditions will not repeat themselves or worsen in the future. If these adverse and volatile market conditions continue, we and other companies in the financial services sector may have to access, if available, alternative markets for debt and equity capital in order to grow. Equity capital may be difficult to raise because, subject to some limited exceptions, as a BDC, we are generally not able to issue additional shares of our common stock at a price less than net asset value without first obtaining approval for such issuance from our stockholders and our independent directors. At our 2011 annual stockholders meeting, subject to certain determinations required to be made by our board of directors, our stockholders approved our ability to sell or otherwise issue shares of our common stock, not exceeding 25% of our then outstanding common stock, at a price below the then current net asset value per share during a period beginning on June 6, 2011 and expiring on the earlier of June 6, 2012 and the date of our 2012 annual stockholders meeting. In addition, our ability to incur indebtedness (including by issuing preferred stock) is limited by applicable regulations such that our asset coverage, as defined in the Investment Company Act, must equal at least 200% immediately after each time we incur indebtedness. The debt capital that will be available to us in the future, if at all, may be at a higher cost and on less favorable terms and conditions than what we currently experience. Any inability to raise capital could have a negative effect on our business, financial condition and results of operations.

        Moreover, the re-appearance of market conditions similar to those experienced from 2007 through 2009 for any substantial length of time could make it difficult to extend the maturity of or refinance our existing indebtedness under similar terms and any failure to do so could have a material adverse effect on our business.

        Given the recent extreme volatility and dislocation in the capital markets, many BDCs have faced, and may in the future face, a challenging environment in which to raise or access capital. At times

31

---

during the recent significant changes in the capital markets, our ability to raise capital was affected and consequently the pace of our investment activity had slowed. In addition, significant changes in the capital markets, including the recent extreme volatility and disruption, has had, and may in the future have, a negative effect on the valuations of our investments and on the potential for liquidity events involving our investments. While most of our investments are not publicly traded, applicable accounting standards require us to assume as part of our valuation process that our investments are sold in a principal market to market participants (even if we plan on holding an investment through its maturity). As a result, volatility in the capital markets can adversely affect our investment valuations. Further, the illiquidity of our investments may make it difficult for us to sell such investments to access capital if required. As a result, we could realize significantly less than the value at which we have recorded our investments if we were required to sell them for liquidity purposes. An inability to raise or access capital could have a material adverse impact on our business, financial condition or results of operations.

A failure on our part to maintain our status as a BDC would significantly reduce our operating flexibility.

        If we fail to maintain our status as a BDC, we might be regulated as a closed-end investment company under the Investment Company Act, which would subject us to additional regulatory restrictions and significantly decrease our operating flexibility. In addition, any such failure could cause an event of default under our outstanding indebtedness, which could have a material adverse effect on our business, financial condition or results of operations.

We are dependent upon certain key personnel of Ares for our future success and upon their access to other Ares investment professionals.

        We depend on the diligence, skill and network of business contacts of certain key personnel of the Ares Private Debt Group. We also depend, to a significant extent, on access to the investment professionals of other groups within Ares and the information and deal flow generated by Ares' investment professionals in the course of their investment and portfolio management activities. Our future success depends on the continued service of the key personnel of the Ares Private Debt Group. The departure of any of these individuals, or of a significant number of the investment professionals or partners of Ares, could have a material adverse effect on our business, financial condition or results of operations. In addition, we cannot assure you that Ares Capital Management will remain our investment adviser or that we will continue to have access to Ares' investment professionals or its information and deal flow.

Our financial condition and results of operations depend on our ability to manage future growth effectively.

        Our ability to achieve our investment objective depends on our ability to acquire suitable investments and monitor and administer those investments, which depends, in turn, on our investment adviser's ability to identify, invest in and monitor companies that meet our investment criteria.

        Accomplishing this result on a cost-effective basis is largely a function of the structuring of our investment process and the ability of our investment adviser to provide competent, attentive and efficient services to us. Our executive officers and the members of our investment adviser's investment committee have substantial responsibilities in connection with their roles at Ares and with the other Ares funds, as well as responsibilities under the investment advisory and management agreement. They may also be called upon to provide significant managerial assistance to certain of our portfolio companies. These demands on their time, which will increase as the number of investments grow, may distract them or slow the rate of investment. In order to grow, Ares will need to hire, train, supervise, manage and retain new employees. However, we cannot assure you that we will be able to do so

effectively. Any failure to manage our future growth effectively could have a material adverse effect on our business, financial condition and results of operations.

        In addition, as we grow, we may open up new offices in new geographic regions that may increase our direct operating expenses without corresponding revenue growth.

We may be unable to realize the benefits anticipated by the Allied Acquisition or it may take longer than anticipated to achieve such benefits.

        On April 1, 2010, we consummated the Allied Acquisition. The realization of certain benefits anticipated as a result of the Allied Acquisition will depend in part on the continued integration of Allied Capital's investment portfolio and business with our investment portfolio and business. The dedication of management resources to the legacy Allied Capital portfolio may detract attention from our day-to-day business, including new origination activity, and there can be no assurance that there will not be material adverse consequences to our business, financial condition and results of operations.

        Further, as a result of the Allied Acquisition, Allied Capital's equity investments, including equity investments larger than those we have traditionally made and controlled portfolio company equity investments, became part of our portfolio. We intend to continue actively seeking opportunities over time to dispose of certain of the assets that were acquired in the Allied Acquisition, particularly non-yielding equity investments, as well as lower or non-yielding debt investments and investments that may not be core to our investment strategy, and generally rotate them into higher-yielding first and second lien senior loans and mezzanine debt investments. However, there can be no assurance that this strategy will be successful. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Portfolio and Investment Activity" for further information on the rotation and repositioning of investments acquired as part of the Allied Acquisition.

Our ability to grow depends on our ability to raise capital.

        We will need to periodically access the capital markets to raise cash to fund new investments. We have elected to be treated as a RIC and operate in a manner so as to qualify for the U.S. federal income tax treatment applicable to RICs. Among other things, in order to maintain our RIC status, we must distribute to our stockholders on a timely basis generally an amount equal to at least 90% of our investment company taxable income, and, as a result, such distributions will not be available to fund investment originations. We must continue to borrow from financial institutions and issue additional securities to fund our growth. Unfavorable economic or capital market conditions may increase our funding costs, limit our access to the capital markets or could result in a decision by lenders not to extend credit to us. An inability to successfully access the capital markets could limit our ability to grow our business and fully execute our business strategy and could decrease our earnings, if any.

        In addition, with certain limited exceptions, we are only allowed to borrow amounts or issue debt securities or preferred stock, which we refer to collectively as "senior securities," such that our asset coverage, as defined in the Investment Company Act, equals at least 200% immediately after such borrowing, which, in certain circumstances, may restrict our ability to borrow or issue debt securities or preferred stock. The amount of leverage that we employ will depend on our investment adviser's and our board of directors' assessments of market and other factors at the time of any proposed borrowing or issuance of senior securities. We cannot assure you that we will be able to maintain our current Facilities, obtain other lines of credit or issue senior securities at all or on terms acceptable to us.

Regulations governing our operation as a BDC affect our ability to, and the way in which we, raise additional capital.

        We may issue senior securities or borrow money from banks or other financial institutions, up to the maximum amount permitted by the Investment Company Act. Under the provisions of the

33

---

Investment Company Act, we are permitted, as a BDC, to incur indebtedness or issue senior securities only in amounts such that our asset coverage, as defined in the Investment Company Act, equals at least 200% after each such incurrence or issuance. If the value of our assets declines, we may be unable to satisfy this test, which may prohibit us from paying dividends and could prevent us from maintaining our status as a RIC or may prohibit us from repurchasing shares of our common stock. In addition, our inability to satisfy this test could cause an event of default under our existing indebtedness. If we cannot satisfy this test, we may be required to sell a portion of our investments at a time when such sales may be disadvantageous and, depending on the nature of our leverage, repay a portion of our indebtedness. Accordingly, any failure to satisfy this test could have a material adverse effect on our business, financial condition or results of operations. As of December 31, 2011, our asset coverage for senior securities was 252%.

        We are not generally able to issue and sell our common stock at a price below net asset value per share. We may, however, sell our common stock, or warrants, options or rights to acquire our common stock, at a price below the current net asset value per share of our common stock if our board of directors determines that such sale is in our best interests and the best interests of our stockholders, and our stockholders approve such sale. Any such sale would be dilutive to the net asset value per share of our common stock. In any such case, the price at which our securities are to be issued and sold may not be less than a price which, in the determination of our board of directors, closely approximates the market value of such securities (less any commission or discount). If our common stock trades at a discount to net asset value, this restriction could adversely affect our ability to raise capital.

        At our 2011 annual stockholders meeting, subject to certain determinations required to be made by our board of directors, our stockholders approved our ability to sell or otherwise issue shares of our common stock, not exceeding 25% of our then outstanding common stock, at a price below the then current net asset value per share during a period beginning on June 6, 2011 and expiring on the earlier of June 6, 2012 and the date of our 2012 annual stockholders meeting.

        To generate cash for funding new investments, we have also securitized, and may in the future seek to securitize, our loans. To securitize loans, we may create a separate, wholly owned subsidiary and contribute or sell a pool of loans to such subsidiary (or one of its subsidiaries). Such subsidiary may then sell equity, issue debt or sell interests in the pool of loans, on a limited-recourse basis, the payments on which are generally limited to the pool of loans and the proceeds therefrom. We may also retain a portion of the equity interests in the securitized pool of loans. Any retained equity would be exposed to losses on the related pool of loans before any of the related debt securities. An inability to successfully securitize our loan portfolio could limit our ability to grow our business and fully execute our business strategy. The securitization market is subject to changing market conditions (including the recent, unprecedented dislocation of the securitization and finance markets generally) and we may not be able to access this market when we would otherwise deem appropriate. Moreover, the successful securitization of our loan portfolio might expose us to losses as the residual loans in which we do not sell interests may be those that are riskier and more apt to generate losses. The Investment Company Act may also impose restrictions on the structure of any securitization.

We borrow money, which magnifies the potential for gain or loss on amounts invested and may increase the risk of investing with us.

        Borrowings, also known as leverage, magnify the potential for gain or loss on amounts invested and, therefore, increase the risks associated with investing in our securities. We currently borrow under our Facilities and have issued or assumed other senior securities, and in the future may borrow from, or issue additional senior securities to, banks, insurance companies, funds, institutional investors and other lenders and investors. Lenders and holders of such senior securities have fixed dollar claims on our consolidated assets that are superior to the claims of our common stockholders or any preferred

34

---

stockholders. If the value of our consolidated assets increases, then leveraging would cause the net asset value per share of our common stock to increase more sharply than it would have had we not incurred leverage.

        Conversely, if the value of our consolidated assets decreases, leveraging would cause net asset value to decline more sharply than it otherwise would have had we not incurred leverage. Similarly, any increase in our consolidated income in excess of consolidated interest payable on the borrowed funds would cause our net income to increase more than it would had we not incurred leverage, while any decrease in our consolidated income would cause net income to decline more sharply than it would have had we not incurred leverage. Such a decline could negatively affect our ability to make common stock dividend payments. There can be no assurance that a leveraging strategy will be successful.

        As of December 31, 2011, we had $858.0 million of outstanding borrowings under our Facilities, $77.5 million in aggregate principal amount outstanding of our CLO Notes (excluding the Retained Notes (as defined below)), $430.0 million in aggregate principal amount outstanding of the Unsecured Notes and $805.0 million in aggregate principal amount outstanding of our Convertible Notes. In addition, since December 31, 2011 we have issued an additional $143.8 million of Unsecured Notes. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Recent Developments" for further information on changes to our indebtedness since December 31, 2011. In order for us to cover our annual interest payments on our outstanding indebtedness at December 31, 2011, we must achieve annual returns on our December 31, 2011 total assets of at least 1.9%. The weighted average stated interest rate charged on our outstanding indebtedness as of December 31, 2011 was 4.8%. We intend to continue borrowing under the Facilities in the future and we may increase the size of the Facilities or issue additional debt securities or other evidences of indebtedness (although there can be no assurance that we will be successful in doing so). Our ability to service our debt depends largely on our financial performance and is subject to prevailing economic conditions and competitive pressures. The amount of leverage that we employ at any particular time will depend on our investment adviser's and our board of directors' assessments of market and other factors at the time of any proposed borrowing.

        Our Facilities, the CLO Notes, the Unsecured Notes and the Convertible Notes impose financial and operating covenants that restrict our business activities, including limitations that could hinder our ability to finance additional loans and investments or to make the distributions required to maintain our status as a RIC. A failure to renew our Facilities or to add new or replacement debt facilities or issue additional debt securities or other evidences of indebtedness could have a material adverse effect on our business, financial condition or results of operations.

        The following table illustrates the effect on return to a holder of our common stock of the leverage created by our use of borrowing at the weighted average stated interest rate of 4.8% as of December 31, 2011, together with (a) our total value of net assets as of December 31, 2011; (b) $2,170.5 million of principal indebtedness outstanding as of December 31, 2011 and (c) hypothetical annual returns on our portfolio of minus 15% to plus 15%.

In addition to regulatory requirements that restrict our ability to raise capital, the Facilities, the CLO Notes, the Unsecured Notes and the Convertible Notes contain various covenants that, if not complied with, could accelerate repayment under the Facilities, the CLO Notes, the Unsecured Notes and the Convertible Notes, thereby materially and adversely affecting our liquidity, financial condition and results of operations.

        The agreements governing the Facilities, the CLO Notes, the Unsecured Notes and the Convertible Notes require us to comply with certain financial and operational covenants. These covenants include:

•

restrictions on the level of indebtedness that we are permitted to incur in relation to the value of our assets;



•

restrictions on our ability to incur liens; and



•

maintenance of a minimum level of stockholders' equity.

        As of the date of this Annual Report, we are in compliance in all material respects with the covenants of the Facilities, the CLO Notes, the Unsecured Notes and the Convertible Notes. However, our continued compliance with these covenants depends on many factors, some of which are beyond our control. For example, depending on the condition of the public debt and equity markets and pricing levels, net unrealized depreciation in our portfolio may increase in the future. Any such increase could result in our inability to comply with our obligation to restrict the level of indebtedness that we are able to incur in relation to the value of our assets or to maintain a minimum level of stockholders' equity.

        Accordingly, although we believe we will continue to be in compliance, there are no assurances that we will continue to comply with the covenants in the Facilities, the CLO Notes, the Unsecured Notes and the Convertible Notes. Failure to comply with these covenants could result in a default under the Facilities, the CLO Notes, the Unsecured Notes or the Convertible Notes that, if we were unable to obtain a waiver from the lenders or holders of such indebtedness, as applicable, such lenders or holders could accelerate repayment under such indebtedness and thereby have a material adverse impact on our business, financial condition and results of operations.

Our credit ratings may change and as a result the cost and flexibility under our debt instruments may change.

        As of December 31, 2011, we had a long-term counterparty credit rating from Standard & Poor's Ratings Services of "BBB," a long-term issuer default rating from Fitch Ratings of "BBB" and a long-term issuer rating from Moody's Investors Service of "Ba1." Interest expense on our Revolving Credit Facility is based on a pricing grid that fluctuates depending on our credit ratings. There can be no assurance that our ratings will be maintained. If our ratings are downgraded, our cost of borrowing will increase.

        In addition, if the ratings of our CLO Notes are downgraded, our ability to engage in certain transactions in respect of the investments held in the Debt Securitization, among other things, may under certain circumstances be restricted and certain principal proceeds may under certain

36

---

circumstances be required to be used to further reduce the outstanding principal balance of the CLO Notes. There can be no assurance that the CLO Notes ratings will be maintained.

        In addition, ratings agencies are required to make substantial changes to their ratings policies and practices as a result of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act"), which President Obama signed into law on July 21, 2010. There can be no assurance that such changes will not affect our ratings.

We operate in a highly competitive market for investment opportunities.

        A number of entities compete with us to make the types of investments that we make in middle-market companies. We compete with other BDCs, public and private funds, commercial and investment banks, commercial financing companies, insurance companies, hedge funds, and, to the extent they provide an alternative form of financing, private equity funds. Many of our competitors are substantially larger and have considerably greater financial, technical and marketing resources than we do. Some competitors may have a lower cost of funds and access to funding sources that are not available to us. In addition, some of our competitors may have higher risk tolerances or different risk assessments, which could allow them to consider a wider variety of investments and establish more relationships than us. Furthermore, many of our competitors are not subject to the regulatory restrictions that the Investment Company Act imposes on us as a BDC and that the Code imposes on us as a RIC. We cannot assure you that the competitive pressures we face will not have a material adverse effect on our business, financial condition and results of operations. Also, as a result of this competition, we may not be able to pursue attractive investment opportunities from time to time.

        We do not seek to compete primarily based on the interest rates we offer and we believe that some of our competitors may make loans with interest rates that are comparable to or lower than the rates we offer. Rather, we compete with our competitors based on our existing investment platform, seasoned investment professionals, experience and focus on middle-market companies, disciplined investment philosophy, extensive industry focus and flexible transaction structuring. For a more detailed discussion of these competitive advantages, see "Business—Competitive Advantages."

        We may lose investment opportunities if we do not match our competitors' pricing, terms and structure. If we match our competitors' pricing, terms and structure, we may experience decreased net interest income and increased risk of credit loss. As a result of operating in such a competitive environment, we may make investments that are on less favorable terms than what we may have originally anticipated, which may impact our return on these investments.

We may be subject to certain corporate-level taxes regardless of whether we continue to qualify as a RIC.

        We have elected to be treated as a RIC under Subchapter M of the Code and operate in a manner so as to qualify for the U.S. federal income tax treatment applicable to RICs. As a RIC, we generally will not pay corporate-level U.S. federal income taxes on our income and gain that we distribute to our stockholders as dividends on a timely basis. To qualify as a RIC, we must meet certain income source, asset diversification and annual distribution requirements (and will pay corporate-level U.S. federal income tax on any undistributed income). We may also be subject to certain U.S. federal excise taxes, as well as state, local and foreign taxes.

        To satisfy the annual distribution requirement for a RIC we must distribute to our stockholders on a timely basis generally an amount equal to at least 90% of our investment company taxable income for each year. Because we use debt financing, we are subject to certain asset coverage ratio requirements under the Investment Company Act and financial covenants under our indebtedness that could, under certain circumstances, restrict us from making distributions necessary to qualify as a RIC. If we are unable to obtain cash from other sources, we may fail to qualify as a RIC and, thus, may be subject to

37

---

corporate-level income tax. We will be subject to corporate-level U.S. federal income tax on any undistributed income and/or gain.

        To qualify as a RIC, we must also meet certain annual income source requirements at the end of each taxable year and asset diversification requirements at the end of each calendar quarter. Failure to meet these tests may result in our having to (a) dispose of certain investments quickly or (b) raise additional capital to prevent the loss of RIC status. Because most of our investments are in private companies and are generally illiquid, any such dispositions may be at disadvantageous prices and may result in losses. Also, the rules applicable to our qualification as a RIC are complex with many areas of uncertainty. Accordingly, no assurance can be given that we have qualified or will continue to qualify as a RIC. If we fail to qualify as a RIC for any reason and become subject to regular "C" corporation income tax, the resulting corporate taxes could substantially reduce our net assets, the amount of income available for distribution and the amount of our distributions. Such a failure would have a material adverse effect on us and our stockholders. The recently enacted "Regulated Investment Company Modernization Act of 2010," which is effective for 2011 and later tax years, provides some relief from RIC disqualification due to failures of the income source and asset diversification requirements, although there may be additional taxes due in such cases. We cannot assure you that we would qualify for any such relief should we fail the income source or asset diversification requirements.

We may have difficulty paying our required distributions under applicable tax rules if we recognize income before or without receiving cash representing such income.

        For U.S. federal income tax purposes, we include in income certain amounts that we have not yet received in cash, such as original issue discount, which may arise if we receive warrants in connection with the making of a loan or possibly in other circumstances, or PIK, which represents contractual interest added to the loan principal balance and due at the end of the loan term. Such original issue discount or PIK interest increases in loan balances are included in income before we receive any corresponding cash payments. We also may be required to include in income certain other amounts that we will not receive in cash, including, for example, amounts attributable to hedging and foreign currency transactions or cancellation of indebtedness income resulting from a restructuring of an investment in debt securities.

        Since, in certain cases, we may recognize income before or without receiving cash in respect of such income, we may have difficulty meeting the U.S. federal income tax requirement to distribute generally an amount equal to at least 90% of our investment company taxable income to maintain our status as a RIC. Accordingly, we may have to sell some of our investments at times we would not consider advantageous, raise additional debt or equity capital or reduce new investment originations to meet these distribution requirements. If we are not able to obtain cash from other sources, we may fail to qualify as a RIC and thus be subject to additional corporate-level taxes.

We may in the future determine to fund a portion of our investments with preferred stock, which would magnify the potential for gain or loss and the risks of investing in us in the same way as our borrowings.

        Because preferred stock is another form of leverage and the dividends on any preferred stock we issue must be cumulative, preferred stock has the same risks to our common stockholders as borrowings. Payment of such dividends and repayment of the liquidation preference of such preferred stock must take preference over any dividends or other payments to our common stockholders, and preferred stockholders are not subject to any of our expenses or losses and are not entitled to participate in any income or appreciation in excess of their stated preference.

38

---

We are exposed to risks associated with changes in interest rates.

        General interest rate fluctuations may have a substantial negative impact on our investments and investment opportunities and, accordingly, may have a material adverse effect on our investment objective and rate of return on invested capital. Because we borrow money and may issue debt securities or preferred stock to make investments, our net investment income is dependent upon the difference between the rate at which we borrow funds or pay interest or dividends on such debt securities or preferred stock and the rate at which we invest these funds. As a result, there can be no assurance that a significant change in market interest rates will not have a material adverse effect on our net investment income.

        Trading prices for debt that pays a fixed rate of return tend to fall as interest rates rise. Trading prices tend to fluctuate more for fixed-rate securities that have longer maturities. In the past, we have entered into certain hedging transactions, such as interest rate swap agreements, to mitigate our exposure to adverse fluctuations in interest rates, and we may do so again in the future. In addition, we may increase our floating rate investments to position the portfolio for rate increases. However, we cannot assure you that such transactions will be successful in mitigating our exposure to interest rate risk. Hedging transactions may also limit our ability to participate in the benefits of lower interest rates with respect to our portfolio investments.

        Although we have no policy governing the maturities of our investments, under current market conditions we expect that we will invest in a portfolio of debt generally having maturities of up to 10 years. This means that we are subject to greater risk (other things being equal) than a fund invested solely in shorter-term securities. A decline in the prices of the debt we own could adversely affect the trading price of our shares. Also, an increase in interest rates available to investors could make an investment in our common stock less attractive if we are not able to increase our dividend rate, which could reduce the value of our common stock.

Many of our portfolio investments are not publicly traded and, as a result, the fair value of these investments may not be readily determinable.

        A large percentage of our portfolio investments are not publicly traded. The fair value of investments that are not publicly traded may not be readily determinable. We value these investments quarterly at fair value as determined in good faith by our board of directors based on, among other things, the input of our management and audit committee and independent valuation firms that have been engaged at the direction of our board of directors to assist in the valuation of each portfolio investment without a readily available market quotation at least once during a trailing 12-month period. The valuation process is conducted at the end of each fiscal quarter, with a minimum of 50% (based on value) of our valuations of portfolio companies without readily available market quotations subject to review by an independent valuation firm each quarter. However, we may use additional independent valuation firms to review the value of our investments more frequently, including in connection with the occurrence of significant events or changes in value affecting a particular investment. In addition, our independent accountants review our valuation process as part of their overall integrated audit. The types of factors that may be considered in valuing our investments include the enterprise value of the portfolio company (an estimate of the total fair value of the portfolio company's debt and equity), the nature and realizable value of any collateral, the portfolio company's ability to make payments and its earnings, the markets in which the portfolio company does business, comparison to publicly traded companies, discounted cash flow and other relevant factors. Because such valuations, and particularly valuations of private investments and private companies, are inherently uncertain, may fluctuate over short periods of time and may be based on estimates, our determinations of fair value may differ materially from the values that would have been used if a ready market for these investments existed and may differ materially from the values that we may ultimately realize. Our net asset value per share

39

---

could be adversely affected if our determinations regarding the fair value of these investments are materially higher than the values that we realize upon disposition of such investments.

The lack of liquidity in our investments may adversely affect our business.

        As we generally make investments in private companies, substantially all of these investments are subject to legal and other restrictions on resale or are otherwise less liquid than publicly traded securities. The illiquidity of our investments may make it difficult for us to sell such investments if the need arises. In addition, if we are required to liquidate all or a portion of our portfolio quickly, we could realize significantly less than the value at which we have recorded our investments. In addition, we may face other restrictions on our ability to liquidate an investment in a portfolio company to the extent that we or an affiliated manager of Ares has material non-public information regarding such portfolio company.

We may experience fluctuations in our quarterly results.

        We could experience fluctuations in our quarterly operating results due to a number of factors, including the interest rates payable on the debt investments we make, the default rates on such investments, the level of our expenses, variations in and the timing of the recognition of realized and unrealized gains or losses, the degree to which we encounter competition in our markets and general economic conditions. As a result of these factors, results for any period should not be relied upon as being indicative of performance in future periods.

There are significant potential conflicts of interest that could impact our investment returns.

        Certain of our executive officers and directors, and members of the investment committee of our investment adviser, serve or may serve as officers, directors or principals of other entities and affiliates of our investment adviser and investment funds managed by our affiliates. Accordingly, they may have obligations to investors in those entities, the fulfillment of which might not be in our or our stockholders' best interests or that may require them to devote time to services for other entities, which could interfere with the time available to provide services to us. Certain members of our investment adviser's investment committee have significant responsibilities for other Ares funds. For example, Messrs. Ressler and Rosenthal are required to devote a substantial majority of their business time to the affairs of ACOF. Similarly, although the professional staff of our investment adviser will devote as much time to the management of the Company as appropriate to enable our investment adviser to perform its duties in accordance with the investment advisory and management agreement, the investment professionals of our investment adviser may have conflicts in allocating their time and services among the Company, on the one hand, and investment vehicles managed by Ares or one or more of its affiliates, on the other hand. These activities could be viewed as creating a conflict of interest insofar as the time and effort of the professional staff of our investment adviser and its officers and employees will not be devoted exclusively to the business of the Company but will instead be allocated between the business of the Company and the management of these other investment vehicles. However, Ares believes that the efforts of such individuals are synergistic with and beneficial to the affairs of Ares Capital, ACOF and these other investment vehicles managed by Ares or its affiliates.

        In addition, certain Ares funds may have investment objectives that compete or overlap with, and may from time to time invest in asset classes similar to those targeted by, Ares Capital. Consequently, we, on the one hand, and these other entities, may from time to time pursue the same or similar capital and investment opportunities. Ares and our investment adviser endeavor to allocate investment opportunities in a fair and equitable manner, and in any event consistent with any fiduciary duties owed to Ares Capital. Nevertheless, it is possible that we may not be given the opportunity to participate in certain investments made by investment funds managed by investment managers affiliated with Ares. In

40

---

addition, there may be conflicts in the allocation of investment opportunities among us and the funds managed by us or one or more of our controlled affiliates or among the funds they manage. We may or may not participate in investments made by funds managed by us or one or more of our controlled affiliates.

        We have from time to time sold assets to certain of the vehicles managed by IHAM and, as part of our investment strategy, we may offer to sell additional assets to vehicles managed by us and/or one or more of our controlled affiliates (including IHAM) or we may purchase assets from vehicles managed by us and/or one or more of our controlled affiliates. In addition, vehicles managed by us or one or more of our controlled affiliates (including IHAM) may offer assets to or may purchase assets from one another. While assets may be sold or purchased at prices that are consistent with those that could be obtained from third parties in the marketplace, and although these types of transactions generally require approval of one or more independent parties, there may be an inherent conflict of interest in such transactions between us and funds managed by us or one of our controlled affiliates.

        We pay management and incentive fees to our investment adviser, and reimburse our investment adviser for certain expenses it incurs. In addition, investors in our common stock will invest on a gross basis and receive distributions on a net basis after expenses, resulting in, among other things, a lower rate of return than one might achieve if distributions were made on a gross basis.

        Our investment adviser's base management fee is based on a percentage of our total assets (other than cash or cash equivalents but including assets purchased with borrowed funds) and, consequently, our investment adviser may have conflicts of interest in connection with decisions that could affect our total assets, such as decisions as to whether to incur indebtedness or to make future investments.

        The part of the incentive fee payable by us to our investment advisor that relates to our pre-incentive fee net investment income is computed and paid on income that may include interest that is accrued but not yet received in cash. If a portfolio company defaults on a loan that is structured to provide accrued interest, it is possible that accrued interest previously used in the calculation of the incentive fee will become uncollectible.

        Our investment advisory and management agreement renews for successive annual periods if approved by our board of directors or by the affirmative vote of the holders of a majority of our outstanding voting securities, including, in either case, approval by a majority of our directors who are not "interested persons" of the Company as defined in Section 2(a)(19) of the Investment Company Act. However, both we and our investment adviser have the right to terminate the agreement without penalty upon 60 days' written notice to the other party. Moreover, conflicts of interest may arise if our investment adviser seeks to change the terms of our investment advisory and management agreement, including, for example, the terms for compensation. While any material change to the investment advisory and management agreement must be submitted to stockholders for approval under the Investment Company Act, we may from time to time decide it is appropriate to seek stockholder approval to change the terms of the agreement.

        We are party to an administration agreement with our administrator, Ares Operations, a wholly owned subsidiary of Ares, pursuant to which our administrator furnishes us with administrative services and we pay our administrator at cost our allocable portion of overhead and other expenses (including travel expenses) incurred by our administrator in performing its obligations under our administration agreement, including our allocable portion of the cost of certain of our officers (including our chief compliance officer, chief financial officer, general counsel, secretary and treasurer) and their respective staffs, but not investment professionals.

        Our portfolio company, IHAM, is party to an administration agreement, referred to herein as the "IHAM administration agreement," with Ares Operations. Pursuant to the IHAM administration agreement, our administrator provides IHAM with administrative services and IHAM reimburses our

41

---

administrator for all of the actual costs associated with such services, including its allocable portion of our administrator's overhead and the cost of our administrator's officers and respective staff in performing its obligations under the IHAM administration agreement. Prior to entering into the IHAM administration agreement, IHAM was party to a services agreement with our investment adviser, pursuant to which our investment adviser provided similar services.

        We are party to an office lease that will expire in February 2026 pursuant to which we are leasing office facilities from a third party. We also entered into separate subleases with Ares Management and IHAM, pursuant to which Ares Management and IHAM sublease approximately 15% and 20%, respectively, of our office space, for a fixed rent equal to 15% and 20%, respectively, of the basic annual rent payable by us under our office lease, plus certain additional costs and expenses.

        As a result of the arrangements described above, there may be times when the management team of Ares (including those members of management focused primarily on managing Ares Capital) has interests that differ from those of our stockholders, giving rise to a conflict.

        Our stockholders may have conflicting investment, tax and other objectives with respect to their investments in us. The conflicting interests of individual stockholders may relate to or arise from, among other things, the nature of our investments, the structure or the acquisition of our investments, and the timing of dispositions of our investments. As a consequence, conflicts of interest may arise in connection with decisions made by our investment adviser, including with respect to the nature or structuring of our investments, that may be more beneficial for one stockholder than for another stockholder, especially with respect to stockholders' individual tax situations. In selecting and structuring investments appropriate for us, our investment adviser will consider the investment and tax objectives of the Company and our stockholders, as a whole, not the investment, tax or other objectives of any stockholder individually.

Changes in laws or regulations governing our operations or the operations of our portfolio companies, changes in the interpretation thereof or newly enacted laws or regulations, such as the Dodd-Frank Act, and any failure by us or our portfolio companies to comply with these laws or regulations, could require changes to certain business practices of us or our portfolio companies, negatively impact the operations, cash flows or financial condition of us or our portfolio companies, impose additional costs on us or our portfolio companies or otherwise adversely affect our business or the business of our portfolio companies.

        We and our portfolio companies are subject to regulation by laws and regulations at the local, state, federal and, in some cases, foreign levels. These laws and regulations, as well as their interpretation, may be changed from time to time, and new laws and regulations may be enacted. Accordingly, any change in these laws or regulations, changes in their interpretation, or newly enacted laws or regulations and any failure by us or our portfolio companies to comply with these laws or regulations, could require changes to certain business practices of us or our portfolio companies, negatively impact the operations, cash flows or financial condition of us or our portfolio companies, impose additional costs on us or our portfolio companies or otherwise adversely affect our business or the business of our portfolio companies.

        On July 21, 2010, President Obama signed into law the Dodd-Frank Act. Many of the provisions of the Dodd-Frank Act have extended implementation periods and delayed effective dates and will require extensive rulemaking by regulatory authorities. In particular, Title IV of the Dodd-Frank Act, the Private Fund Investment Advisers Registration Act of 2010 (the "Advisers Registration Act"), eliminates the "private adviser exemption" from SEC registration currently contained in Section 203(b)(3) of the Advisers Act and requires private advisers who had been relying on that exemption to register with the SEC by March 30, 2012. This provision exempted from registration investment advisers who do not hold themselves out to the public as investment advisers and have fewer than 15 clients. As a result,

42

---

many investment advisers to private funds (with some exceptions) will be required to register with the SEC and will become subject to substantial regulatory reporting and recordkeeping requirements regarding the private funds they advise. Consequently, the Advisers Registration Act will likely require our wholly owned portfolio company, IHAM, to register as an investment adviser under the Advisers Act. This would require IHAM to comply with the regulatory restrictions and obligations imposed on registered investment advisers generally. In addition, as a BDC, we are currently restricted in our ability to invest in a registered investment adviser.

        We are seeking relief from the SEC to enable us to continue to invest in IHAM following any registration by IHAM as a registered investment adviser; however, there can be no assurance that such relief will be granted. If we are not able to obtain such relief, we may not be able to make future investments in IHAM, which could harm IHAM's business and the performance of our investment in IHAM or we may be forced to dispose of our interests in IHAM at a time or in a manner we would not consider to be advantageous.

        While the impact of the Dodd-Frank Act on us and our portfolio companies may not be known for an extended period of time, the Dodd-Frank Act, including future rules implementing its provisions and the interpretation of those rules, along with other legislative and regulatory proposals directed at the financial services industry or affecting taxation that are proposed or pending in the U.S. Congress, may negatively impact the operations, cash flows or financial condition of us or our portfolio companies, impose additional costs on us or our portfolio companies, intensify the regulatory supervision of us or our portfolio companies or otherwise adversely affect our business or the business of our portfolio companies.

Our investment adviser's liability is limited under the investment advisory and management agreement, and we are required to indemnify our investment adviser against certain liabilities, which may lead our investment adviser to act in a riskier manner on our behalf than it would when acting for its own account.

        Our investment adviser has not assumed any responsibility to us other than to render the services described in the investment advisory and management agreement, and it will not be responsible for any action of our board of directors in declining to follow our investment adviser's advice or recommendations. Pursuant to the investment advisory and management agreement, our investment adviser and its members and their respective officers, managers, partners, agents, employees, controlling persons and members and any other person or entity affiliated with it will not be liable to us for their acts under the investment advisory and management agreement, absent willful misfeasance, bad faith, gross negligence or reckless disregard in the performance of their duties. We have agreed to indemnify, defend and protect our investment adviser and its members and their respective officers, managers, partners, agents, employees, controlling persons and members and any other person or entity affiliated with it with respect to all damages, liabilities, costs and expenses resulting from acts of our investment adviser not arising out of willful misfeasance, bad faith, gross negligence or reckless disregard in the performance of their duties under the investment advisory and management agreement. These protections may lead our investment adviser to act in a riskier manner when acting on our behalf than it would when acting for its own account. See "Risk Factors—Risks Relating to Our Investments—Our investment adviser's incentive fee may induce it to make certain investments, including speculative investments."

We may be obligated to pay our investment adviser incentive compensation even if we incur a loss.

        Our investment adviser is entitled to incentive compensation for each fiscal quarter in an amount equal to a percentage of the excess of our pre-incentive fee net investment income for that quarter (before deducting incentive compensation and certain other items) above a threshold return for that quarter. Our pre-incentive fee net investment income for incentive compensation purposes excludes

43

---

realized and unrealized capital losses or depreciation and income taxes related to realized gains that we may incur in the fiscal quarter, even if such capital losses or depreciation and income taxes related to realized gains result in a net loss on our statement of operations for that quarter. Thus, we may be required to pay our investment adviser incentive compensation for a fiscal quarter even if there is a decline in the value of our portfolio or we incur a net loss for that quarter.

        Under the investment advisory and management agreement, we will defer cash payment of any incentive fee otherwise earned by our investment adviser if, during the most recent four full calendar quarter periods ending on or prior to the date such payment is to be made, the sum of (a) our aggregate distributions to our stockholders and (b) our change in net assets (defined as total assets less indebtedness and before taking into account any incentive fees payable during the period) is less than 7.0% of our net assets (defined as total assets less indebtedness) at the beginning of such period. These calculations will be adjusted for any share issuances or repurchases. Any deferred incentive fees will be carried over for payment in subsequent calculation periods to the extent such payment can then be made under the investment advisory and management agreement.

        If a portfolio company defaults on a loan that is structured to provide accrued interest, it is possible that accrued interest previously used in the calculation of the incentive fee will become uncollectible. Our investment adviser is not under any obligation to reimburse us for any part of the incentive fee it received that was based on accrued income that we never receive as a result of a default on the obligation that resulted in the accrual of such income.

We may not replicate Ares' historical success and our ability to enter into transactions with Ares and our other affiliates is restricted.

        We cannot assure you that Ares Capital will replicate Ares' historical success, and we caution you that our investment returns could be substantially lower than the returns achieved by other Ares managed funds.

        Further, we and certain of our controlled affiliates are prohibited under the Investment Company Act from knowingly participating in certain transactions with our upstream affiliates, or our investment adviser and its affiliates, without the prior approval of our independent directors and, in some cases, the SEC. Any person that owns, directly or indirectly, 5% or more of our outstanding voting securities is our upstream affiliate for purposes of the Investment Company Act and we are generally prohibited from buying or selling any security (other than our securities) from or to such affiliate, absent the prior approval of our independent directors. The Investment Company Act also prohibits "joint" transactions with an upstream affiliate, or our investment adviser or its affiliates, which could include investments in the same portfolio company (whether at the same or different times), without prior approval of our independent directors. In addition, we and certain of our controlled affiliates are prohibited from buying or selling any security from or to, or entering into joint transactions with, our investment adviser and its affiliates, or any person who owns more than 25% of our voting securities or is otherwise deemed to control, be controlled by, or be under common control with us, absent the prior approval of the SEC through an exemptive order (other than in certain limited situations pursuant to current regulatory guidance). The analysis of whether a particular transaction constitutes a joint transaction requires a review of the relevant facts and circumstances.

        We have applied for an exemptive order from the SEC that would permit us and certain of our controlled affiliates to co-invest with funds managed by Ares. Any such order, if issued, will be subject to certain terms and conditions and there can be no assurance that such order will be granted by the SEC. Accordingly, we cannot assure you that we or our controlled affiliates will be permitted to co-invest with funds managed by Ares, other than in the limited circumstances currently permitted by regulatory guidance or in the absence of a joint transaction.

RISKS RELATING TO OUR INVESTMENTS

Declines in market prices and liquidity in the corporate debt markets can result in significant net unrealized depreciation of our portfolio, which in turn would reduce our net asset value.

        As a BDC, we are required to carry our investments at market value or, if no market value is ascertainable, at fair value as determined in good faith by or under the direction of our board of directors. We may take into account the following types of factors, if relevant, in determining the fair value of our investments: the enterprise value of a portfolio company (an estimate of the total fair value of the portfolio company's debt and equity), the nature and realizable value of any collateral, the portfolio company's ability to make payments and its earnings and discounted cash flow, the markets in which the portfolio company does business, a comparison of the portfolio company's securities to similar publicly traded securities, changes in the interest rate environment and the credit markets generally that may affect the price at which similar investments may be made in the future and other relevant factors. When an external event such as a purchase transaction, public offering or subsequent equity sale occurs, we use the pricing indicated by the external event to corroborate our valuation. While most of our investments are not publicly traded, applicable accounting standards require us to assume as part of our valuation process that our investments are sold in a principal market to market participants (even if we plan on holding an investment through its maturity). As a result, volatility in the capital markets can also adversely affect our investment valuations. Decreases in the market values or fair values of our investments are recorded as unrealized depreciation. The effect of all of these factors on our portfolio can reduce our net asset value by increasing net unrealized depreciation in our portfolio. Depending on market conditions, we could incur substantial realized losses and may suffer unrealized losses, which could have a material adverse impact on our business, financial condition and results of operations.

Economic recessions or downturns could impair our portfolio companies and harm our operating results.

        Many of our portfolio companies may be susceptible to economic downturns or recessions (including the recent economic downturn that began in 2007) and may be unable to repay our loans during these periods. Therefore, during these periods our non-performing assets may increase and the value of our portfolio may decrease if we are required to write down the values of our investments. Adverse economic conditions may also decrease the value of collateral securing some of our loans and the value of our equity investments. Economic slowdowns or recessions could lead to financial losses in our portfolio and a decrease in revenues, net income and assets. Unfavorable economic conditions also could increase our funding costs, limit our access to the capital markets or result in a decision by lenders not to extend credit to us. These events could prevent us from increasing investments and harm our operating results. We experienced to some extent such effects during the recent economic downturn and may experience such effects again in any future downturn or recession.

        A portfolio company's failure to satisfy financial or operating covenants imposed by us or other lenders could lead to defaults and, potentially, acceleration of the time when the loans are due and foreclosure on its assets representing collateral for its obligations, which could trigger cross defaults under other agreements and jeopardize our portfolio company's ability to meet its obligations under the debt that we hold and the value of any equity securities we own. We may incur expenses to the extent necessary to seek recovery upon default or to negotiate new terms with a defaulting portfolio company.

Investments in privately held middle-market companies involve significant risks.

        We primarily invest in privately held U.S. middle-market companies. Investments in privately held middle-market companies involve a number of significant risks, including the following:

•

these companies may have limited financial resources and may be unable to meet their obligations, which may be accompanied by a deterioration in the value of any collateral and a reduction in the likelihood of us realizing any guarantees we may have obtained in connection with our investment;



•

they typically have shorter operating histories, narrower product lines and smaller market shares than larger businesses, which tend to render them more vulnerable to competitors' actions and market conditions, as well as general economic downturns;



•

they typically depend on the management talents and efforts of a small group of persons; therefore, the death, disability, resignation or termination of one or more of these persons could have a material adverse impact on our portfolio company and, in turn, on us;



•

there is generally little public information about these companies. These companies and their financial information are not subject to the Exchange Act and other regulations that govern public companies, and we may be unable to uncover all material information about these companies, which may prevent us from making a fully informed investment decision and cause us to lose money on our investments;



•

they generally have less predictable operating results and may require substantial additional capital to support their operations, finance expansion or maintain their competitive position;



•

our executive officers, directors and our investment adviser may, in the ordinary course of business, be named as defendants in litigation arising from our investments in the portfolio companies; and



•

they may have difficulty accessing the capital markets to meet future capital needs.

Our debt investments may be risky and we could lose all or part of our investment.

        The debt that we invest in is typically not initially rated by any rating agency, but we believe that if such investments were rated, they would be below investment grade (rated lower than "Baa3" by Moody's Investors Service, lower than "BBB-" by Fitch Ratings or lower than "BBB-" by Standard & Poor's Ratings Services). Indebtedness of below investment grade quality is regarded as having predominantly speculative characteristics with respect to the issuer's capacity to pay interest and repay principal. Therefore, our investments may result in an above average amount of risk and volatility or loss of principal. We also invest in assets other than first and second lien and mezzanine debt investments, including high-yield securities, U.S. government securities, credit derivatives and other structured securities and certain direct equity investments. These investments entail additional risks that could adversely affect our investment returns.

Investments in equity securities, many of which are illiquid with no readily available market, involve a substantial degree of risk.

        We may purchase common and other equity securities. Although common stock has historically generated higher average total returns than fixed income securities over the long-term, common stock also has experienced significantly more volatility in those returns and in recent years has significantly under performed relative to fixed income securities. The equity securities we acquire may fail to appreciate and may decline in value or become worthless and our ability to recover our investment will

46

---

depend on our portfolio company's success. Investments in equity securities involve a number of significant risks, including:

•

any equity investment we make in a portfolio company could be subject to further dilution as a result of the issuance of additional equity interests and to serious risks as a junior security that will be subordinate to all indebtedness (including trade creditors) or senior securities in the event that the issuer is unable to meet its obligations or becomes subject to a bankruptcy process;



•

to the extent that the portfolio company requires additional capital and is unable to obtain it, we may not recover our investment; and



•

in some cases, equity securities in which we invest will not pay current dividends, and our ability to realize a return on our investment, as well as to recover our investment, will be dependent on the success of the portfolio company. Even if the portfolio company is successful, our ability to realize the value of our investment may be dependent on the occurrence of a liquidity event, such as a public offering or the sale of the portfolio company. It is likely to take a significant amount of time before a liquidity event occurs or we can otherwise sell our investment. In addition, the equity securities we receive or invest in may be subject to restrictions on resale during periods in which it could be advantageous to sell them.

        There are special risks associated with investing in preferred securities, including:

•

preferred securities may include provisions that permit the issuer, at its discretion, to defer distributions for a stated period without any adverse consequences to the issuer. If we own a preferred security that is deferring its distributions, we may be required to report income for tax purposes before we receive such distributions;



•

preferred securities are subordinated to debt in terms of priority to income and liquidation payments, and therefore will be subject to greater credit risk than debt;



•

preferred securities may be substantially less liquid than many other securities, such as common stock or U.S. government securities; and



•

generally, preferred security holders have no voting rights with respect to the issuing company, subject to limited exceptions.

        Additionally, when we invest in first and second lien senior loans or mezzanine debt, we may acquire warrants or other equity securities as well. Our goal is ultimately to dispose of such equity interests and realize gains upon our disposition of such interests. However, the equity interests we receive may not appreciate in value and, in fact, may decline in value. Accordingly, we may not be able to realize gains from our equity interests and any gains that we do realize on the disposition of any equity interests may not be sufficient to offset any other losses we experience.

        We may invest, to the extent permitted by law, in the equity securities of investment funds that are operating pursuant to certain exceptions to the Investment Company Act and in advisers to similar investment funds and, to the extent we so invest, will bear our ratable share of any such company's expenses, including management and performance fees. We will also remain obligated to pay management and incentive fees to Ares Capital Management with respect to the assets invested in the securities and instruments of such companies. With respect to each of these investments, each of our common stockholders will bear his or her share of the management and incentive fee of Ares Capital Management as well as indirectly bearing the management and performance fees and other expenses of any such investment funds or advisers.

        As a result of the Allied Acquisition, Allied Capital's equity investments, including equity investments larger than those we have traditionally made and controlled portfolio company equity

47

---

investments, became part of our portfolio. We intend to continue actively seeking opportunities over time to dispose of certain of these investments and generally rotate them into higher-yielding first and second lien senior loans and mezzanine debt or other investments. However, there can be no assurance that this strategy will be successful.

There may be circumstances where our debt investments could be subordinated to claims of other creditors or we could be subject to lender liability claims.

        If one of our portfolio companies were to go bankrupt, even though we may have structured our interest as senior debt, depending on the facts and circumstances, a bankruptcy court might recharacterize our debt holding as an equity investment and subordinate all or a portion of our claim to that of other creditors. In addition, lenders can be subject to lender liability claims for actions taken by them where they become too involved in the borrower's business or exercise control over the borrower. For example, we could become subject to a lender's liability claim, if, among other things, we actually render significant managerial assistance.

Our portfolio companies may incur debt or issue equity securities that rank equally with, or senior to, our investments in such companies.

        Our portfolio companies may have, or may be permitted to incur, other debt, or issue other equity securities, that rank equally with, or senior to, our investments. By their terms, such instruments may provide that the holders are entitled to receive payment of dividends, interest or principal on or before the dates on which we are entitled to receive payments in respect of our investments. These debt instruments would usually prohibit the portfolio companies from paying interest on or repaying our investments in the event and during the continuance of a default under such debt. Also, in the event of insolvency, liquidation, dissolution, reorganization or bankruptcy of a portfolio company, holders of securities ranking senior to our investment in that portfolio company typically are entitled to receive payment in full before we receive any distribution in respect of our investment. After repaying such holders, the portfolio company may not have any remaining assets to use for repaying its obligation to us. In the case of securities ranking equally with our investments, we would have to share on an equal basis any distributions with other security holders in the event of an insolvency, liquidation, dissolution, reorganization or bankruptcy of the relevant portfolio company.

        The rights we may have with respect to the collateral securing any junior priority loans we make to our portfolio companies may also be limited pursuant to the terms of one or more intercreditor agreements that we enter into with the holders of senior debt. Under such an intercreditor agreement, at any time that senior obligations are outstanding, we may forfeit certain rights with respect to the collateral to the holders of the senior obligations. These rights may include the right to commence enforcement proceedings against the collateral, the right to control the conduct of such enforcement proceedings, the right to approve amendments to collateral documents, the right to release liens on the collateral and the right to waive past defaults under collateral documents. We may not have the ability to control or direct such actions, even if as a result our rights as junior lenders are adversely affected.

When we are a debt or minority equity investor in a portfolio company, we are often not in a position to exert influence on the entity, and other equity holders and management of the company may make decisions that could decrease the value of our portfolio holdings.

        When we make debt or minority equity investments, we are subject to the risk that a portfolio company may make business decisions with which we disagree and the other equity holders and management of such company may take risks or otherwise act in ways that do not serve our interests. As a result, a portfolio company may make decisions that could decrease the value of our investment.

48

---

Our portfolio companies may be highly leveraged.

        Some of our portfolio companies may be highly leveraged, which may have adverse consequences to these companies and to us as an investor. These companies may be subject to restrictive financial and operating covenants and the leverage may impair these companies' ability to finance their future operations and capital needs. As a result, these companies' flexibility to respond to changing business and economic conditions and to take advantage of business opportunities may be limited. Further, a leveraged company's income and net assets will tend to increase or decrease at a greater rate than if borrowed money were not used.

Our investment adviser's incentive fee may induce it to make certain investments, including speculative investments.

        The incentive fee payable by us to Ares Capital Management may create an incentive for Ares Capital Management to make investments on our behalf that are risky or more speculative than would be the case in the absence of such compensation arrangement. The way in which the incentive fee payable to our investment adviser is determined, which is calculated as a percentage of the return on invested capital, may encourage our investment adviser to use leverage to increase the return on our investments. Under certain circumstances, the use of leverage may increase the likelihood of default, which would disfavor the holders of our common stock and the holders of securities convertible into our common stock. In addition, our investment adviser will receive the incentive fee based, in part, upon net capital gains realized on our investments. Unlike the portion of the incentive fee based on income, there is no hurdle rate applicable to the portion of the incentive fee based on net capital gains. As a result, our investment adviser may have a tendency to invest more in investments that are likely to result in capital gains as compared to income producing securities. Such a practice could result in our investing in more speculative securities than would otherwise be the case, which could result in higher investment losses, particularly during economic downturns.

        The part of the incentive fee payable by us that relates to our pre-incentive fee net investment income will be computed and paid on income that may include interest that is accrued but not yet received in cash. If a portfolio company defaults on a loan that is structured to provide accrued interest, it is possible that accrued interest previously used in the calculation of the incentive fee will become uncollectible. Our investment adviser is not under any obligation to reimburse us for any part of the incentive fee it received that was based on such accrued interest that we never actually receive.

        Because of the structure of the incentive fee, it is possible that we may have to pay an incentive fee in a quarter where we incur a loss. For example, if we receive pre-incentive fee net investment income in excess of the hurdle rate for a quarter, we will pay the applicable incentive fee even if we have incurred a loss in that quarter due to realized and/or unrealized capital losses. In addition, if market interest rates rise, we may be able to invest our funds in debt instruments that provide for a higher return, which would increase our pre-incentive fee net investment income and make it easier for our investment adviser to surpass the fixed hurdle rate and receive an incentive fee based on such net investment income.

Our investments in foreign companies may involve significant risks in addition to the risks inherent in U.S. investments. We may also expose ourselves to risks if we engage in hedging transactions.

        Our investment strategy contemplates potential investments in foreign companies. Investing in foreign companies may expose us to additional risks not typically associated with investing in U.S. companies. These risks include changes in exchange control regulations, political and social instability, expropriation, imposition of foreign taxes (potentially at confiscatory levels), less liquid markets, less available information than is generally the case in the United States, higher transaction costs, less government supervision of exchanges, brokers and issuers, less developed bankruptcy laws, difficulty in

49

---

enforcing contractual obligations, lack of uniform accounting and auditing standards and greater price volatility.

        Although most of our investments will be U.S. dollar denominated, our investments that are denominated in a foreign currency will be subject to the risk that the value of a particular currency will change in relation to one or more other currencies. Among the factors that may affect currency values are trade balances, the level of short-term interest rates, differences in relative values of similar assets in different currencies, long-term opportunities for investment and capital appreciation and political developments. We may employ hedging techniques to minimize these risks, but we cannot assure you that such strategies will be effective or without risk to us.

        We have and may in the future enter into hedging transactions, which may expose us to risks associated with such transactions. We may utilize instruments such as forward contracts, currency options and interest rate swaps, caps, collars and floors to seek to hedge against fluctuations in the relative values of our portfolio positions from changes in currency exchange rates and market interest rates. Use of these hedging instruments may include counter-party credit risk.

        Hedging against a decline in the values of our portfolio positions does not eliminate the possibility of fluctuations in the values of such positions or prevent losses if the values of such positions decline. However, such hedging can establish other positions designed to gain from those same developments, thereby offsetting the decline in the value of such portfolio positions. Such hedging transactions may also limit the opportunity for gain if the values of the underlying portfolio positions should increase. Moreover, it may not be possible to hedge against an exchange rate or interest rate fluctuation that is so generally anticipated that we are not able to enter into a hedging transaction at an acceptable price.

        The success of our hedging transactions will depend on our ability to correctly predict movements in currencies and interest rates. Therefore, while we may enter into such transactions to seek to reduce currency exchange rate and interest rate risks, unanticipated changes in currency exchange rates or interest rates may result in poorer overall investment performance than if we had not engaged in any such hedging transactions. In addition, the degree of correlation between price movements of the instruments used in a hedging strategy and price movements in the portfolio positions being hedged may vary. Moreover, for a variety of reasons, we may not seek to (or be able to) establish a perfect correlation between such hedging instruments and the portfolio holdings being hedged. Any such imperfect correlation may prevent us from achieving the intended hedge and expose us to risk of loss. In addition, it may not be possible to hedge fully or perfectly against currency fluctuations affecting the value of securities denominated in non-U.S. currencies because the value of those securities is likely to fluctuate as a result of factors not related to currency fluctuations. See also "Risk Factors—Risk Relating to Our Business—We are exposed to risks associated with changes in interest rates."

RISKS RELATING TO OUR COMMON STOCK AND PUBLICLY TRADED NOTES

Our shares of common stock have traded at a discount from net asset value and may do so again in the future, which could limit our ability to raise additional equity capital.

        Shares of closed-end investment companies frequently trade at a market price that is less than the net asset value that is attributable to those shares. This characteristic of closed-end investment companies is separate and distinct from the risk that our net asset value per share may decline. It is not possible to predict whether any shares of our common stock will trade at, above, or below net asset value. In the recent past, including during much of 2009, the stocks of BDCs as an industry, including at times shares of our common stock, traded below net asset value and at near historic lows as a result of concerns over liquidity, leverage restrictions and distribution requirements. When our common stock is trading below its net asset value per share, we will generally not be able to issue additional shares of our common stock at its market price without first obtaining approval for such issuance from our stockholders and our independent directors. At our 2011 annual stockholders meeting, subject to

50

---

certain determinations required to be made by our board of directors, our stockholders approved our ability to sell or otherwise issue shares of our common stock, not exceeding 25% of our then outstanding common stock, at a price below the then current net asset value per share during a period beginning on June 6, 2011 and expiring on the earlier of June 6, 2012 and the date of our 2012 annual stockholders meeting.

There is a risk that investors in our common stock may not receive dividends or that our dividends may not grow over time and that investors in our debt securities may not receive all of the interest income to which they are entitled.

        We intend to make distributions on a quarterly basis to our stockholders out of assets legally available for distribution. We cannot assure you that we will achieve investment results that will allow us to make a specified level of cash distributions or year-to-year increases in cash distributions. If we declare a dividend and if more stockholders opt to receive cash distributions rather than participate in our dividend reinvestment plan, we may be forced to sell some of our investments in order to make cash dividend payments.

        In addition, due to the asset coverage test applicable to us as a BDC, we may be limited in our ability to make distributions. Further, if we invest a greater amount of assets in equity securities that do not pay current dividends, it could reduce the amount available for distribution. See "Dividend/Distribution Policy."

        The above-referenced restrictions on distributions may also inhibit our ability to make required interest payments to holders of our debt, which may cause a default under the terms of our debt agreements. Such a default could materially increase our cost of raising capital, as well as cause us to incur penalties under the terms of our debt agreements.

Provisions of the Maryland General Corporation Law and of our charter and bylaws could deter takeover attempts and have an adverse impact on the price of our common stock.

        The Maryland General Corporation Law, our charter and our bylaws contain provisions that may discourage, delay or make more difficult a change in control of Ares Capital or the removal of our directors. We are subject to the Maryland Business Combination Act (the "Business Combination Act"), subject to any applicable requirements of the Investment Company Act. Our board of directors has adopted a resolution exempting from the Business Combination Act any business combination between us and any other person, subject to prior approval of such business combination by our board, including approval by a majority of our disinterested directors. If the resolution exempting business combinations is repealed or our board or disinterested directors do not approve a business combination, the Business Combination Act may discourage third parties from trying to acquire control of us and increase the difficulty of consummating such an offer. Our bylaws exempt from the Maryland Control Share Acquisition Act (the "Control Share Acquisition Act") acquisitions of our stock by any person. If we amend our bylaws to repeal the exemption from the Control Share Acquisition Act, the Control Share Acquisition Act also may make it more difficult for a third party to obtain control of us and increase the difficulty of consummating such an offer.

        We have also adopted measures that may make it difficult for a third party to obtain control of us, including provisions of our charter classifying our board of directors into three classes serving staggered three-year terms, and provisions of our charter authorizing our board of directors to classify or reclassify shares of our stock into one or more classes or series, to cause the issuance of additional shares of our stock, and to amend our charter from time to time, without stockholder approval, to increase or decrease the aggregate number of shares of stock or the number of shares of stock of any class or series that we have authority to issue. These provisions, as well as other provisions of our

51

---

charter and bylaws, may discourage, delay, defer, make more difficult or prevent a transaction or a change in control that might otherwise be in the best interests of our stockholders.

Investing in our common stock may involve an above average degree of risk.

        The investments we make in accordance with our investment objective may result in a higher amount of risk than alternative investment options and volatility or loss of principal. Our investments in portfolio companies may be highly speculative and aggressive and, therefore, an investment in our securities may not be suitable for someone with lower risk tolerance.

The market price of our common stock may fluctuate significantly.

        The capital and credit markets have experienced a period of extreme volatility and disruption that began in 2007. The market price and liquidity of the market for shares of our common stock may be significantly affected by numerous factors, some of which are beyond our control and may not be directly related to our operating performance. These factors include:

•

significant volatility in the market price and trading volume of securities of publicly traded RICs, BDCs or other companies in our sector, which are not necessarily related to the operating performance of these companies;



•

price and volume fluctuations in the overall stock market from time to time;



•

changes in law, regulatory policies or tax guidelines, or interpretations thereof, particularly with respect to RICs or BDCs;



•

loss of our RIC status;



•

changes in our earnings or variations in our operating results;



•

changes in the value of our portfolio of investments;



•

any shortfall in revenue or net income or any increase in losses from levels expected by investors or securities analysts;



•

departure of Ares Capital Management's key personnel;



•

operating performance of companies comparable to us;



•

short-selling pressure with respect to shares of our common stock or BDCs generally;



•

future sales of our securities convertible into or exchangeable or exercisable for our common stock or the conversion of such securities, including the Convertible Notes;



•

uncertainty surrounding the strength of the U.S. economic recovery;



•

concerns regarding European sovereign debt;



•

general economic trends and other external factors; and



•

loss of a major funding source.

        In the past, following periods of volatility in the market price of a company's securities, securities class action litigation has often been brought against that company. If our stock price fluctuates significantly, we may be the target of securities litigation in the future. Securities litigation could result in substantial costs and divert management's attention and resources from our business.

Our stockholders will experience dilution in their ownership percentage if they opt out of our dividend reinvestment plan.

        All dividends declared in cash payable to stockholders that are participants in our dividend reinvestment plan are automatically reinvested in shares of our common stock. As a result, our stockholders that opt out of our dividend reinvestment plan will experience dilution in their ownership percentage of our common stock over time.

Our stockholders may experience dilution upon the conversion of the Convertible Notes.

        The February 2016 Convertible Notes are convertible into shares of our common stock beginning August 15, 2015 or, under certain circumstances, earlier and the June 2016 Convertible Notes are convertible into shares of our common stock beginning on December 15, 2015 or, under certain circumstances, earlier. Upon conversion of the Convertible Notes, we have the choice to pay or deliver, as the case may be, at our election, cash, shares of our common stock or a combination of cash and shares of our common stock. The current conversion price of the February 2016 Convertible Notes is approximately $19.13 per share of common stock and the current conversion price of the June 2016 Convertible Notes is approximately $19.04 per share, in each case subject to adjustment in certain circumstances. If we elect to deliver shares of common stock upon a conversion at the time our tangible book value per share exceeds the conversion price in effect at such time, our stockholders may incur dilution. In addition, our stockholders will experience dilution in their ownership percentage of common stock upon our issuance of common stock in connection with the conversion of the Convertible Notes and any dividends paid on our common stock will also be paid on shares issued in connection with such conversion after such issuance.

Our stockholders may receive shares of our common stock as dividends, which could result in adverse tax consequences to them.

        In order to satisfy the annual distribution requirement applicable to RICs, we have the ability to declare a large portion of a dividend in shares of our common stock instead of in cash. As long as a portion of such dividend is paid in cash (which portion can be as low as 10% for dividends declared with respect to our taxable years ending on or before December 31, 2011) and certain requirements are met, the entire distribution would be treated as a dividend for U.S. federal income tax purposes. As a result, a stockholder would be taxed on 100% of the fair market value of the dividend on the date a stockholder received it in the same manner as a cash dividend, even though most of the dividend was paid in shares of our common stock.

Sales of substantial amounts of our common stock in the public market may have an adverse effect on the market price of our common stock.

        Sales of substantial amounts of our common stock, or the availability of such common stock for sale (including as a result of the conversion of our Convertible Notes into common stock), could adversely affect the prevailing market prices for our common stock. If this occurs and continues, it could impair our ability to raise additional capital through the sale of securities should we desire to do so.

The trading market or market value of our publicly issued debt securities may fluctuate.

        Our publicly issued debt securities may or may not have an established trading market. We cannot assure you that a trading market for our publicly issued debt securities will ever develop or be maintained if developed. In addition to our creditworthiness, many factors may materially adversely

53

---

affect the trading market for, and market value of, our publicly issued debt securities. These factors include, but are not limited to, the following:

•

the time remaining to the maturity of these debt securities;



•

the outstanding principal amount of debt securities with terms identical to these debt securities;



•

the ratings assigned by national statistical ratings agencies;



•

the general economic environment;



•

the supply of debt securities trading in the secondary market, if any;



•

the redemption or repayment features, if any, of these debt securities;



•

the level, direction and volatility of market interest rates generally; and



•

market rates of interest higher or lower than rates borne by the debt securities.

        You should also be aware that there may be a limited number of buyers when you decide to sell your debt securities. This too may materially adversely affect the market value of the debt securities or the trading market for the debt securities.

Terms relating to redemption may materially adversely affect your return on any debt securities that we may issue.

        If your debt securities are redeemable at our option, we may choose to redeem your debt securities at times when prevailing interest rates are lower than the interest rate paid on your debt securities. In addition, if your debt securities are subject to mandatory redemption, we may be required to redeem your debt securities also at times when prevailing interest rates are lower than the interest rate paid on your debt securities. In this circumstance, you may not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as your debt securities being redeemed.

Our credit ratings may not reflect all risks of an investment in our debt securities.

        Our credit ratings are an assessment by third parties of our ability to pay our obligations. Consequently, real or anticipated changes in our credit ratings will generally affect the market value of our debt securities. Our credit ratings, however, may not reflect the potential impact of risks related to market conditions generally or other factors discussed above on the market value of or trading market for the publicly issued debt securities.

Item 1B.    Unresolved Staff Comments

        None.

Item 2.    Properties

        We do not own any real estate or other physical properties materially important to our operation. Our headquarters are currently located at 245 Park Avenue, 44^th Floor, New York, New York 10167. We rent the office space directly from a third party pursuant to a lease that expires in February 2026. We also entered into separate subleases with Ares Management and IHAM, pursuant to which Ares Management and IHAM sublease approximately 15% and 20%, respectively, of our office space, for a fixed rent equal to 15% and 20%, respectively, of the basic annual rent payable by us under our office lease, plus certain additional costs and expenses.

Item 3.    Legal Proceedings

        We are party to certain lawsuits in the normal course of business. Allied Capital was also involved in various other legal proceedings that we assumed in connection with the Allied Acquisition. Furthermore, third parties may try to seek to impose liability on us in connection with the activities of our portfolio companies. While the outcome of any such legal proceedings cannot at this time be predicted with certainty, we do not expect these matters will materially affect our business, financial condition or results of operations.

Item 4.    Mine Safety Disclosures

        Not applicable.

PART II

Item 5.    Market For Registrant's Common Equity, Related Stockholder Matters And Issuer Purchases Of Equity Securities

PRICE RANGE OF COMMON STOCK

        Our common stock is traded on The NASDAQ Global Select Market under the symbol "ARCC." We completed our initial public offering in October 2004 at a price of $15.00 per share. Prior to October 2004, there was no public market for our common stock. Our common stock has historically traded at prices both above and below our net asset value per share. It is not possible to predict whether our common stock will trade at, above or below net asset value. See "Risk Factors—Risks Relating to our Common Stock and Publicly Traded Notes—Our shares of common stock may trade at discounts from net asset value, which limits our ability to raise additional equity capital."

        The following table sets forth the net asset value per share of our common stock, the range of high and low closing sales prices of our common stock as reported on The NASDAQ Global Select Market and the dividends declared by us for each fiscal quarter for the years ended December 31, 2010 and 2011. On February 24, 2012, the last reported closing sales price of our common stock on The NASDAQ Global Select Market was $16.13 per share, which represented a premium of approximately 5% to the net asset value per share reported by us as of December 31, 2011.

HOLDERS

        As of February 24, 2012, there were 2,067 holders of record of our common stock (including Cede & Co.).

DIVIDEND/DISTRIBUTION POLICY

        We currently intend to distribute quarterly dividends or distributions to our stockholders. Our quarterly dividends or distributions, if any, are determined by our board of directors.

        The following table summarizes our dividends and distributions declared during 2010 and 2011:

        Of the dividends and distributions declared during the year ended December 31, 2010, the entire $1.40 per share was comprised of ordinary income. Of the $1.41 per share in dividends and distributions declared during the year ended December 31, 2011, $1.16 per share was comprised of ordinary income and $0.25 per share was comprised of long-term capital gains.

        To maintain our RIC status, we must timely distribute an amount equal to at least 90% of our investment company taxable income (as defined by the Code, which generally includes net ordinary income and net short term taxable gains) to our stockholders. In addition, the Company generally will be required to pay an excise tax equal to 4% of the amount by which (i) 98% of the Company's ordinary income recognized during a calendar year and (ii) 98.2% of the Company's capital gain net income, as defined by the Code, recognized for the one year period ending on October 31^st of a calendar year exceeds the distributions for the year. The taxable income on which excise tax is paid is generally distributed to stockholders in the next tax year. Depending on the level of taxable income earned in a tax year, we may choose to carry forward taxable income for distribution in the following year, and pay any applicable excise tax. For the years ended December 31, 2011 and 2010, we recorded an excise tax expense of $6.6 million and $2.2 million, respectively. We cannot assure you that we will achieve results that will permit the payment of any cash distributions. We maintain an "opt out" dividend reinvestment plan for our common stockholders. As a result, if we declare a cash dividend, then stockholders' cash dividends will be automatically reinvested in additional shares of our common stock, unless they specifically opt out of the dividend reinvestment plan so as to receive cash dividends.

RECENT SALES OF UNREGISTERED EQUITY SECURITIES

        We did not sell any equity securities during the period covered by this report that were not registered under the Securities Act.

ISSUER PURCHASES OF EQUITY SECURITIES

        For the year ended December 31, 2011, as a part of our dividend reinvestment plan for our common stockholders, we purchased 785,226 shares of our common stock in the open market.

OVERVIEW

        We are a specialty finance company that is a closed-end, non-diversified management investment company incorporated in Maryland. We have elected to be regulated as a BDC under the Investment Company Act. We were founded on April 16, 2004, were initially funded on June 23, 2004 and on October 8, 2004 completed our initial public offering.

        Our investment objective is to generate both current income and capital appreciation through debt and equity investments. We invest primarily in first and second lien senior loans and mezzanine debt, which in some cases includes an equity component like warrants.

        To a lesser extent, we also make preferred and/or common equity investments, which have generally been non-control equity investments, of less than $20 million (usually in conjunction with a concurrent debt investment). However, we may increase the size or change the nature of these investments. Also, as a result of the Allied Acquisition, Allied Capital's equity investments, which included equity investments larger than those we have historically made and controlled portfolio company equity investments, became part of our portfolio. We intend to continue actively seeking opportunities over time to dispose of certain of the assets that were acquired in the Allied Acquisition, particularly non-yielding equity investments and controlled portfolio company investments, as well as lower or non-yielding debt investments and investments that may not be core to our investment strategy, and generally rotate them into higher-yielding first and second lien senior loans and mezzanine debt investments. However, there can be no assurance that this strategy will be successful.

        We are externally managed by Ares Capital Management, a wholly owned subsidiary of Ares, a global alternative asset manager and an SEC-registered investment adviser, pursuant to an investment advisory and management agreement. Ares Operations, a wholly owned subsidiary of Ares, provides the administrative services necessary for us to operate.

        As a BDC, we are required to comply with certain regulatory requirements. For instance, we generally have to invest at least 70% of our total assets in "qualifying assets," including securities and indebtedness of private U.S. companies and certain public U.S. companies, cash, cash equivalents, U.S. government securities and high-quality debt investments that mature in one year or less.

        We have elected to be treated as a RIC under Subchapter M of the Code and operate in a manner so as to qualify for the tax treatment applicable to RICs. To qualify as a RIC, we must, among other things, meet certain source-of-income and asset diversification requirements and timely distribute to our stockholders generally at least 90% of our investment company taxable income, as defined by the Code, for each year. Pursuant to this election, we generally will not have to pay corporate level taxes on any income that we distribute to our stockholders provided that we satisfy those requirements.

Allied Acquisition

        On April 1, 2010, we consummated the Allied Acquisition in an all stock merger whereby each existing share of common stock of Allied Capital was exchanged for 0.325 shares of our common stock.

62

---

The Allied Acquisition was valued at approximately $908 million as of April 1, 2010. In connection therewith, we issued approximately 58.5 million shares of our common stock to Allied Capital's then-existing stockholders, resulting in our then-existing stockholders owning approximately 69% of the combined company and the then-existing Allied Capital stockholders owning approximately 31% of the combined company.

        Information presented herein as of and for the years ended December 31, 2011 and December 31, 2010 includes the results of operations and financial condition of the combined company following the Allied Acquisition unless otherwise indicated in the footnotes. Information presented herein as of and for the year ended December 31, 2009 relates solely to Ares Capital, as it existed before the Allied Acquisition.

PORTFOLIO AND INVESTMENT ACTIVITY

        The Company's investment activity for the years ended December 31, 2011, 2010 and 2009 is presented below (information presented herein is at amortized cost unless otherwise indicated).

        As of December 31, 2011 and 2010, the investment portfolio consisted of the following:

        The weighted average yields at fair value and amortized cost of the following portions of our portfolio as of December 31, 2011 and 2010 were as follows:

65

---

        Below is certain information regarding changes in the investments acquired in the Allied Acquisition since April 1, 2010 through December 31, 2011:

        Since April 1, 2010, the date that we consummated the Allied Acquisition, through December 31, 2011, we have decreased the assets comprising the legacy Allied Capital portfolio by approximately $1,053 million, primarily as a result of exits and repayments of approximately $1,208 million and net unrealized depreciation in the portfolio of approximately $49 million, net of other increases of approximately $203 million due to fundings of revolving and other commitments of $131 million, PIK interest and accretion of purchase discounts. From April 1, 2010 through December 31, 2011, we also recognized $122 million in net realized gains on the exits and repayments of investments acquired in the Allied Acquisition resulting in total proceeds received from exits and repayments of $1,329 million. We intend to continue actively seeking opportunities over time to dispose of certain of the assets that were acquired in the Allied Acquisition, particularly non-yielding equity investments and controlled portfolio company equity investments, as well as lower or non-yielding debt investments and investments that may not be core to our investment strategy, and generally rotate them into higher-yielding first and second lien senior loans and mezzanine debt investments. However, there can be no assurance that this strategy will be successful. For risks relating to our equity investments, see "Risk Factors—Risks Relating to Our Investments—Investments in equity securities, many of which are illiquid with no readily available market, involve a substantial degree of risk."

        Ares Capital Management LLC, our investment adviser, employs an investment rating system to categorize our investments. In addition to various risk management and monitoring tools, our investment adviser grades the credit risk of all investments on a scale of 1 to 4 no less frequently than quarterly. This system is intended primarily to reflect the underlying risk of a portfolio investment relative to our initial cost basis in respect of such portfolio investment (i.e., at the time of acquisition), although it may also take into account under certain circumstances the performance of the portfolio company's business, the collateral coverage of the investment and other relevant factors. Under this system, investments with a grade of 4 involve the least amount of risk to our initial cost basis. The trends and risk factors for this investment since origination or acquisition are generally favorable, which may include the performance of the portfolio company or a potential exit. Investments graded 3 involve a level of risk to our initial cost basis that is similar to the risk to our initial cost basis at the time of origination or acquisition. This portfolio company is generally performing as expected and the risk

66

---

factors to our ability to ultimately recoup the cost of our investment are neutral to favorable. All investments or acquired investments in new portfolio companies are initially assessed a grade of 3. Investments graded 2 indicate that the risk to our ability to recoup the initial cost basis of such investment has increased materially since origination or acquisition, including as a result of factors such as declining performance and non-compliance with debt covenants; however, payments are generally not more than 120 days past due. An investment grade of 1 indicates that the risk to our ability to recoup the initial cost basis of such investment has substantially increased since origination or acquisition, and the portfolio company likely has materially declining performance. For debt investments with an investment grade of 1, most or all of the debt covenants are out of compliance and payments are substantially delinquent. For investments graded 1, it is anticipated that we will not recoup our initial cost basis and may realize a substantial loss of our initial cost basis upon exit. For investments graded 1 or 2, our investment adviser enhances its level of scrutiny over the monitoring of such portfolio company. Our investment adviser grades the investments in our portfolio at least each quarter and it is possible that the grade of certain of these portfolio investments may be reduced or increased over time.

        Set forth below is the grade distribution of our portfolio companies as of December 31, 2011 and 2010:

        As of December 31, 2011, the weighted average grade of the investments in our portfolio (excluding investments acquired in connection with the Allied Acquisition), the investments in our portfolio acquired in connection with the Allied Acquisition and the investments in our portfolio as a whole were 3.1, 2.8 and 3.0, respectively. As of December 31, 2010, the weighted average grade of the investments in our portfolio (excluding investments acquired in connection with the Allied Acquisition), the investments in our portfolio acquired in connection with the Allied Acquisition and the investments in our portfolio as a whole were each 3.1.

        Investments on non-accrual status as of December 31, 2011 and December 31, 2010, were as follows:

RESULTS OF OPERATIONS

For the years ended December 31, 2011, 2010 and 2009

        Operating results for the years ended December 31, 2011, 2010 and 2009 are as follows:

Investment Income

        The increase in interest income for the year ended December 31, 2011 as compared to 2010 was primarily due to the increase in the size of the portfolio, which increased from an average of $3.7 billion at amortized cost for the year ended December 31, 2010 to an average of $4.6 billion at amortized cost in 2011. The increase in capital structuring service fees for the year ended December 31, 2011 as compared to 2010 was primarily due to the increase in new investment commitments, which increased from $1.7 billion for the year ended December 31, 2010 to $3.7 billion for the comparable period in 2011. The increase in dividend income for the year ended December 31, 2011 as compared to 2010 is primarily attributable to dividend income from IHAM which was $7.3 million for the year ended December 31, 2010 and $19.0 million for the comparable period in 2011, which resulted from the growth of and increased earnings in IHAM. In addition, there was an increase in dividends from certain portfolio companies in which we have an equity investment. Total dividend income for the year ended December 31, 2011 included $10.3 million of dividend income that was non-recurring in nature from non-income producing equity securities. Management fees for the year ended December 31, 2011 included management fees earned from the SSLP totaling $11.6 million, as compared to $5.9 million for 2010. Additionally management fees earned related to investments and management contracts acquired in the Allied Acquisition decreased to $3.6 million for the year ended December 31, 2011 from $7.2 million in 2010.

68

---

        The increase in interest income for the year ended December 31, 2010 as compared to 2009 was primarily due to the increase in the size of the portfolio, which was largely due to the investments acquired as part of the Allied Acquisition. Interest income from investments acquired as part of the Allied Acquisition was approximately $139.2 million for the year ended December 31, 2010. The remainder of the increase in interest income was due to an increase in the Ares Capital investment portfolio, which increased from an average of $2.3 billion at amortized cost for the year ended December 31, 2009 to an average of $2.5 billion at amortized cost for the comparable period in 2010. The increase in capital structuring service fees for the year ended December 31, 2010 was primarily due to the increase in new investment commitments, which increased from $480 million for the year ended December 31, 2009 to $1.7 billion for the comparable period in 2010. The increase in dividend income for the year ended December 31, 2010 as compared to 2009 was primarily attributable to dividend income from IHAM, which was $2.5 billion for the year ended December 31, 2009 and $7.3 million for 2010. Total dividend income for the year ended December 31, 2010 included $2.6 million of dividend income that was non-recurring in nature from non-income producing equity securities. The increase in management fees for the year ended December 31, 2010 as compared to 2009 was primarily due to the management fees earned from the SSLP, which increased from $0.6 million for the year ended December 31, 2009 to $5.9 million for the comparable period in 2010 as the SSLP increased from approximately $900 million aggregate principal amount of investments at December 31, 2009 to approximately $2.5 billion principal amount of investments at December 31, 2010. Additionally, management fees earned related to investments and management contracts acquired in the Allied Acquisition were $7.2 million for the year ended December 31, 2010.

Operating Expenses

        Interest and credit facility fees for the years ended December 31, 2011 and 2010, were comprised of the following:

69

---

        Stated interest expense for the year ended December 31, 2011 increased from 2010 due to the increase in our average principal debt outstanding and an increase in our weighted average stated interest rate. For 2011, our average principal debt outstanding was $1.8 billion as compared to $1.5 billion for 2010, and the weighted average stated interest rate on our debt was 5.1% as compared to 3.9% for 2010. Our weighted average stated interest rate of our debt for 2011 increased from 2010 due to having higher amounts of unsecured indebtedness, with longer durations to maturity and higher stated interest rates, outstanding during 2011. Amortization of debt issuance costs for the year ended December 31, 2011 increased from 2010 primarily due to the debt issuance costs associated with the Convertible Notes issued in early 2011.

        Stated interest expense for the year ended December 31, 2010 increased from 2009 due to the increase in our average principal debt outstanding and an increase in our weighted average stated interest rate. For 2010, the average principal debt outstanding was $1.5 billion as compared to $870 million for 2009, and the weighted average stated interest rate on our debt was 3.9% as compared to 2.2% for 2009. In connection with the Allied Acquisition, we acquired $746 million in principal amount of debt on April 1, 2010, which had a weighted average stated interest rate of 6.56% and resulted in total interest expense for the year ended December 31, 2010 of $43.5 million, including $8.2 million of purchased discount accretion.

        The increase in base management fees and incentive management fees related to pre-incentive fee net investment income for the year ended December 31, 2011 from 2010 was primarily due to the increase in the size of the portfolio and in the case of incentive management fees, the related increase in pre-incentive fee net investment income. For the year ended December 31, 2011, the capital gains incentive fee expense was $33.3 million bringing the total capital gains incentive fee accrual in accordance with GAAP to $48.9 million (included in management and incentive fees payable in the consolidated balance sheet) as of December 31, 2011. As a result of the Capital Gains Amendment, the year ended December 31, 2011 included an accrual of $26.0 million of capital gains incentive fees in accordance with GAAP as a result of the application of the Capital Gains Amendment with respect to the assets purchased in the Allied Acquisition. The accrual for any capital gains incentive fee under GAAP in a given period may result in an additional expense if such cumulative amount is greater than in the prior period or a reduction of previously recorded expense if such cumulative amount is less than in the prior period. If such cumulative amount is negative, then there is no accrual. There can be no assurance that such unrealized capital appreciation will be realized in the future. For the year ended December 31, 2011 we did not incur a capital gains fee under the investment advisory and management agreement and therefore there are no amounts currently due under the agreement. See Note 3 to the Company's consolidated financial statements for the year ended December 31, 2011 for more information on the incentive and base management fees.

        Incentive and base management fees for the year ended December 31, 2010 increased from 2009 primarily due to the increase in the size of the portfolio and in the case of the incentive fees, the related increase in net investment income as well as the net appreciation of the investment portfolio. In 2010 we did not incur a Capital Gains Fee under the investment advisory and management agreement; however, in accordance with GAAP, we accrued $15.6 million in incentive management fees as a result of the unrealized appreciation in the portfolio. In 2009 we did not incur a Capital Gains Fee under the investment advisory and management agreement or record any such fee in accordance with GAAP.

        Professional fees include legal, accounting, valuation and other professional fees incurred related to the management of the Company. Administrative fees represent fees paid to Ares Operations for our allocable portion of overhead and other expenses incurred by Ares Operations in performing its obligations under the administration agreement, including our allocable portion of the cost of certain of our executive officers and their respective staffs. Other general and administrative expenses include rent, insurance, depreciation, director's fees and other costs. The general increases in professional fees and administrative fees were primarily due to the increase in the size of the company following the

Allied Acquisition and the various associated costs of managing a larger portfolio. The decline in professional fees and other costs related to the Allied Acquisition for the year ended December 31, 2011 as compared to 2010, primarily resulted from having substantially completed the integration of Allied Capital by December 31, 2010. The increase in professional fees and other costs related to the Allied Acquisition for the year ended December 31, 2010 as compared to 2009 were primarily as a result of the occurrence of various closing and transition related costs following the Allied Acquisition.

Income Tax Expense, Including Excise Tax

        The Company has elected to be treated as a RIC under Subchapter M of the Code and operates in a manner so as to qualify for the tax treatment applicable to RICs. To qualify as a RIC, the Company must, among other things, timely distribute to its stockholders generally at least 90% of its investment company taxable income, as defined by the Code, for each year. In order to maintain its RIC status, the Company, among other things, has made and intends to continue to make the requisite distributions to its stockholders which will generally relieve the Company from U.S. federal income taxes.

        Depending on the level of taxable income earned in a tax year, we may choose to carry forward taxable income in excess of current year dividend distributions from such current year taxable income into the next tax year and pay a 4% excise tax on such income, as required. To the extent that the Company determines that its estimated current year annual taxable income will be in excess of estimated current year dividend distributions from such income, the Company accrues excise tax on estimated excess taxable income. For the years ended December 31, 2011 and 2010, a net expense of $6.6 million and $2.2 million was recorded for U.S. federal excise tax, respectively. For the year ended December 31, 2009 a net benefit of $0.1 million was recorded for U.S. federal excise tax.

        Certain of our wholly owned subsidiaries are subject to U.S. federal and state income taxes. For the years ended December 31, 2011, 2010 and 2009, we recorded a tax expense of approximately $0.9 million, $3.2 million and $0.6 million, respectively, for these subsidiaries.

Net Realized Gains/Losses

        During the year ended December 31, 2011, the Company had $2.5 billion of sales, repayments or exits of investments resulting in $96.6 million of net realized gains.

Net realized gains of $96.6 million on investments were comprised of $249.1 million of gross realized gains and $152.5 million of gross realized losses. These net realized gains included approximately $86.9 million in net realized gains from investments acquired as part of the Allied Acquisition (see Note 17 to the Company's consolidated financial

FINANCIAL CONDITION, LIQUIDITY, AND CAPITAL RESOURCES

        The Company's liquidity and capital resources have been generated primarily from the net proceeds of public offerings of common stock, the Debt Securitization, advances from the Facilities, net proceeds from the issuance of unsecured notes as well as cash flows from operations. As part of the Allied Acquisition, the Company assumed all outstanding debt obligations of Allied Capital, including the Allied Unsecured Notes, which at the time consisted of the 2011 Notes, the 2012 Notes and the 2047 Notes.

        As of December 31, 2011, the Company had $120.8 million in cash and cash equivalents and $2.1 billion in total indebtedness outstanding at carrying value ($2.2 billion at principal amount). Subject to leverage and borrowing base restrictions, the Company had approximately $404.8 million available for additional borrowings under the Facilities as of December 31, 2011.

        We may from time to time seek to retire or repurchase our common stock through cash purchases, as well as retire, cancel or purchase our outstanding debt through cash purchases and/or exchanges, in open market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will depend on prevailing market conditions, our liquidity requirements, contractual and regulatory restrictions and other factors. The amounts involved may be material.

Equity Issuances

        The ratio of total principal amount of debt outstanding to stockholders' equity as of December 31, 2011 was 0.69:1.00 compared to 0.47:1.00 as of December 31, 2010. The ratio of total carrying value of debt outstanding to stockholders' equity as of December 31, 2011 was 0.66:1.00 compared to 0.45:1.00 as of December 31, 2010.

        In accordance with the Investment Company Act, with certain limited exceptions, we are only allowed to borrow amounts such that our asset coverage, as defined in the Investment Company Act, is at least 200% after such borrowing. As of December 31, 2011, our asset coverage for borrowed amounts was 252%.

Revolving Funding Facility

        Our wholly owned subsidiary, Ares Capital CP, is party to the Revolving Funding Facility, which, as amended, currently provides for up to $500 million of borrowings. The Revolving Funding Facility is secured by all of the assets held by, and the membership interest in, Ares Capital CP. On January 18, 2011, the Revolving Funding Facility was amended to, among other things, provide for a three year reinvestment period until January 18, 2014 (with two one-year extension options, subject to our and our lenders' consent) and extend the stated maturity date to January 18, 2016 (with two one-year extension options subject to our and our lenders' consent). On October 13, 2011, the Revolving Funding Facility was amended to increase the facility to the current size of $500 million. As of December 31, 2011, subject to certain exceptions, the interest rate charged on the Revolving Funding Facility is based on LIBOR plus an applicable spread of between 2.25% and 3.75% or on a "base rate" (which is the higher of a prime rate, or the federal funds rate plus 0.50%) plus an applicable spread of between 1.25% to 2.75%, in each case based on a pricing grid depending upon our credit rating. Additionally, we are required to pay a commitment fee of between 0.50% and 2.00% depending on the usage level on any unused portion of the Revolving Funding Facility. As of December 31, 2011, the effective LIBOR spread under the Revolving Funding Facility was 2.75%. As of December 31, 2011, the principal amount outstanding under the Revolving Funding Facility was $463.0 million and the Company was in material compliance with the terms of the Revolving Funding Facility.

Revolving Credit Facility

        We are party to the Revolving Credit Facility that currently provides for up to $810 million of borrowings. The Revolving Credit Facility also includes an "accordion" feature that allows us, under certain circumstances, to increase the size of the facility to a maximum of $1.05 billion. Subject to certain exceptions, the interest rate charged on the Revolving Credit Facility is based on LIBOR plus an applicable spread of between 2.50% and 4.00% or on the "alternate base rate" plus an applicable spread of between 1.50% and 3.00%, in each case, based on a pricing grid depending upon our credit rating. As of December 31, 2011, the effective LIBOR spread under the Revolving Credit Facility was 3.00%. As of December 31, 2011, there was $395.0 million outstanding under the Revolving Credit Facility and the Company was in material compliance with the terms of the Revolving Credit Facility.

Debt Securitization

        In July 2006, through ARCC Commercial Loan Trust 2006, a vehicle serviced by our wholly owned subsidiary ARCC CLO, we completed the $400 million Debt Securitization and issued approximately $314 million aggregate principal amount of the CLO Notes to third parties that were secured by a pool of middle-market loans purchased or originated by the Company. We initially retained approximately $86 million of aggregate principal amount outstanding of certain "BBB" and non-rated securities in the Debt Securitization. As of December 31, 2011, our total holdings of CLO Notes, including $34.8 million of CLO Notes repurchased in the first quarter of 2009, was $120.8 million (the "Retained Notes"). During the years ended December 31, 2011 and 2010, we repaid $77.8 million and $118.5 million, respectively, of the CLO Notes. As of December 31, 2011, $77.5 million was outstanding under the Debt Securitization (excluding the Retained Notes), which are included in our December 31, 2011 consolidated balance sheet.

        The CLO Notes, have a stated maturity of December 20, 2019 and have a blended interest rate charged of LIBOR plus 0.45% as of December 31, 2011. As of December 31, 2011 the Company was in material compliance with the terms of the Debt Securitization.

Unsecured Notes

Allied Unsecured Notes

        As part of the Allied Acquisition, the Company assumed all outstanding debt obligations of Allied Capital, including Allied Capital's unsecured notes, which consisted of 6.625% Notes due on July 15, 2011 (the "2011 Notes"), 6.000% Notes due on April 1, 2012 (the "2012 Notes") and 6.875% Notes due on April 15, 2047 (the "2047 Notes" and, together with the 2011 Notes and the 2012 Notes, the "Allied Unsecured Notes"). On March 16, 2011 we redeemed the remaining balance of the 2011 Notes for a total redemption price (including a redemption premium) of $306.8 million, in accordance with the terms of the indenture governing the 2011 Notes, which resulted in a loss on the extinguishment of debt of $8.9 million. On April 27, 2011, we redeemed the remaining balance of the 2012 Notes for a total redemption price (including a redemption premium) of $169.3 million, in accordance with the terms of the indenture governing the 2012 Notes, which resulted in a loss on the extinguishment of debt of $10.5 million.

        As of December 31, 2011, there was $230.0 million aggregate principal amount outstanding of the 2047 Notes which bear interest at a rate of 6.875% and mature on April 15, 2047. The 2047 Notes require payment of interest quarterly, and all principal is due upon maturity. These notes are redeemable in whole or in part at any time or from time to time at our option on or after April 15, 2012, at a par redemption price of $25 per security plus accrued and unpaid interest and upon the occurrence of certain tax events as stipulated in the indenture governing the 2047 Notes.

2040 Notes

        On October 21, 2010, we issued $200 million in aggregate principal amount of senior unsecured notes which bear interest at a rate of 7.75% and mature on October 15, 2040. The 2040 Notes require payment of interest quarterly, and all principal is due upon maturity. These notes are redeemable in whole or in part at any time or from time to time at our option on or after October 15, 2015, at a par redemption price of $25 per security plus accrued and unpaid interest.

        As of December 31, 2011 the Company was in material compliance with the terms of the 2047 Notes and the 2040 Notes.

Convertible Notes

February 2016 Convertible Notes

        In January 2011, we issued $575 million in aggregate principal amount of unsecured convertible senior notes that mature on February 1, 2016, unless previously converted or repurchased in accordance with their terms. We do not have the right to redeem the February 2016 Convertible Notes prior to maturity. The February 2016 Convertible Notes bear interest at a rate of 5.75% per year, payable semi-annually. In certain circumstances, the February 2016 Convertible Notes will be convertible into cash, shares of our common stock or a combination of cash and shares of our common stock, at our election, at an initial conversion rate of 52.2766 shares of common stock per $1,000 principal amount of the February 2016 Convertible Notes, which was equivalent to an initial conversion price of approximately $19.13 per share of our common stock, subject to customary anti-dilution adjustments. The initial conversion price was approximately 17.5% above the $16.28 per share closing price of our common stock on January 19, 2011.

        Prior to the close of business on the business day immediately preceding August 15, 2015, holders may convert their February 2016 Convertible Notes only under certain circumstances set forth in the indenture governing the terms of the February 2016 Convertible Notes (the "February 2016 Indenture"). On or after August 15, 2015 until the close of business on the scheduled trading day immediately preceding February 1, 2016, holders may convert their February 2016 Convertible Notes at any time. Upon conversion, we will pay or deliver, as the case may be, at our election, cash, shares of our common stock or a combination of cash and shares of our common stock, subject to the requirements of the February 2016 Indenture.

June 2016 Convertible Notes

        In March 2011, we issued $230 million in aggregate principal amount of unsecured convertible senior notes that mature on June 1, 2016, unless previously converted or repurchased in accordance with their terms. We do not have the right to redeem the June 2016 Convertible Notes prior to maturity. The June 2016 Convertible Notes bear interest at a rate of 5.125% per year, payable semi-annually. In certain circumstances, the June 2016 Convertible Notes will be convertible into cash, shares of our common stock or a combination of cash and shares of our common stock, at our election,

81

---

at an initial conversion rate of 52.5348 shares of common stock per $1,000 principal amount of the June 2016 Convertible Notes, which was equivalent to an initial conversion price of approximately $19.04 per share of our common stock, subject to customary anti-dilution adjustments. The initial conversion price was approximately 17.5% above the $16.20 per share closing price of our common stock on March 22, 2011.

        Prior to the close of business on the business day immediately preceding December 15, 2015, holders may convert their June 2016 Convertible Notes only under certain circumstances set forth in the indenture governing the terms of the June 2016 Convertible Notes (the "June 2016 Indenture"). On or after December 15, 2015 until the close of business on the scheduled trading day immediately preceding June 1, 2016, holders may convert their June 2016 Convertible Notes at any time. Upon conversion, we will pay or deliver, as the case may be, at our election, cash, shares of our common stock or a combination of cash and shares of our common stock, subject to the requirements of the June 2016 Indenture.

        The Convertible Notes are our senior unsecured obligations and rank senior in right of payment to our existing and future indebtedness that is expressly subordinated in right of payment to the Convertible Notes; equal in right of payment to our existing and future unsecured indebtedness that is not expressly subordinated; effectively junior in right of payment to any of our secured indebtedness (including existing unsecured indebtedness that we later secure) to the extent of the value of the assets securing such indebtedness; and structurally junior to all existing and future indebtedness (including trade payables) incurred by our subsidiaries, financing vehicles or similar facilities.

        As of December 31, 2011, the Company was in material compliance with the terms of the indentures governing the Convertible Notes.

        See Note 5 to our consolidated financial statements for the year ended December 31, 2011 for more detail on the Company's debt obligations. See "Recent Developments" and Note 19 to our consolidated financial statements for the year ended December 31, 2011 for information on a new revolving funding facility and unsecured notes issuance, both completed subsequent to December 31, 2011.

CONTRACTUAL OBLIGATIONS

        A summary of the maturities our contractual payment obligations as of December 31, 2011 are as follows:

82

---

PORTFOLIO VALUATION

        Investment transactions are recorded on the trade date. Realized gains or losses are measured by the difference between the net proceeds from the repayment or sale and the amortized cost basis of the investment without regard to the unrealized gains or losses previously recognized, and include investments charged off during the period, net of recoveries. Unrealized gains or losses primarily reflect the change in investment values, including the reversal of previously recorded unrealized gains or losses when gains or losses are realized. Investments for which market quotations are readily available are typically valued at such market quotations. In order to validate market quotations, we look at a number of factors to determine if the quotations are representative of fair value, including the source and nature of the quotations. Debt and equity securities that are not publicly traded or whose market prices are not readily available (i.e., substantially all of our investments) are valued at fair value as determined in good faith by our board of directors, based on, among other things, the input of our investment adviser, audit committee and independent third-party valuation firms that have been engaged at the direction of our board of directors to assist in the valuation of each portfolio investment without a readily available market quotation at least once during a trailing 12-month period, and under a valuation policy and a consistently applied valuation process. The valuation process is conducted at the end of each fiscal quarter, and a minimum of 50% of our portfolio at fair value is subject to review by an independent valuation firm each quarter. In addition, our independent accountants review our valuation process as part of their overall integrated audit.

        As part of the valuation process, we may take into account the following types of factors, if relevant, in determining the fair value of our investments: the enterprise value of a portfolio company (an estimate of the total fair value of the portfolio company's debt and equity), the nature and realizable value of any collateral, the portfolio company's ability to make payments and its earnings and discounted cash flow, the markets in which the portfolio company does business, a comparison of the portfolio company's securities to any similar publicly traded securities, changes in the interest rate environment and the credit markets generally that may affect the price at which similar investments may be made in the future and other relevant factors. When an external event such as a purchase transaction, public offering or subsequent equity sale occurs, we consider the pricing indicated by the external event to corroborate our valuation.

        Because there is not a readily available market value for most of the investments in our portfolio, we value substantially all of our portfolio investments at fair value as determined in good faith by our board of directors as described herein. Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the fair value of our investments may fluctuate from period to period. Additionally, the fair value of our investments may differ significantly from the values that would have been used had a ready market existed for such investments and may differ materially from the values that we may ultimately realize. Further, such investments are generally subject to legal and other restrictions on resale or otherwise are less liquid than publicly traded securities. If we were required to liquidate a portfolio investment in a forced or liquidation sale, we could realize significantly less than the value at which we have recorded it.

        In addition, changes in the market environment and other events that may occur over the life of the investments may cause the gains or losses ultimately realized on these investments to be different than the gains or losses reflected in the valuations currently assigned. See "Risk Factors—Risks Relating to our Investments—Declines in market prices and liquidity in the corporate debt markets can result in significant net unrealized depreciation of our portfolio, which in turn would reduce our net asset value."

83

---

        Our board of directors undertakes a multi-step valuation process each quarter, as described below:

•

Our quarterly valuation process begins with each portfolio company or investment being initially valued by the investment professionals responsible for the portfolio investment in conjunction with our portfolio management team.



•

Preliminary valuations are reviewed and discussed with our investment adviser's management and investment professionals, and then valuation recommendations are presented to our board of directors.



•

The audit committee of our board of directors reviews these valuations, as well as the input of third parties, including independent third-party valuation firms, with respect to the valuations of a minimum of 50% of our portfolio at fair value.



•

Our board of directors discusses valuations and determines the fair value of each investment in our portfolio without a readily available market quotation in good faith based on, among other things, the input of our investment adviser, audit committee and where applicable, independent third-party valuation firms.

        Effective January 1, 2008, the Company adopted ASC 820-10 (previously SFAS No. 157, Fair Value Measurements), which expands the application of fair value accounting for investments (see Note 8 to the Company's consolidated financial statements for the year ended December 31, 2011). Investments acquired as part of the Allied Acquisition were accounted for in accordance with ASC 805-10 (previously SFAS No. 141(R), Business Combinations), which requires that all assets be recorded at fair value. As a result, the initial amortized cost basis and fair value for the acquired investments were the same at April 1, 2010 (see Note 17 to the Company's consolidated financial statements for the year ended December 31, 2011).

OFF BALANCE SHEET ARRANGEMENTS

        The Company has various commitments to fund investments in its portfolio, as described below.

        As of December 31, 2011 and 2010, the Company had the following commitments to fund various revolving and delayed draw senior secured and subordinated loans, including commitments the funding of which is at (or substantially at) the Company's discretion:

        Included within the total revolving and delayed draw commitments as of December 31, 2011 are commitments to issue up to $79.4 million in standby letters of credit through a financial intermediary on behalf of certain portfolio companies. Under these arrangements, if the standby letters of credit were to be issued, the Company would be required to make payments to third parties if the portfolio companies were to default on their related payment obligations. As of December 31, 2011, the Company had $43.3 million in standby letters of credit issued and outstanding under these commitments on behalf of the portfolio companies, of which no amounts were recorded as a liability on

84

---

our balance sheet as such letters of credit are considered in the valuation of the investments in the portfolio company. Of these letters of credit $41.2 million expire in 2012 and $2.1 million expire in 2013.

        As of December 31, 2011 and 2010, the Company was party to subscription agreements to fund equity investments in private equity investment partnerships:

        In the ordinary course of business, Allied Capital had issued guarantees on behalf of certain portfolio companies. Under these arrangements, payments would be required to be made to third parties if the portfolio companies were to default on their related payment. As part of the Allied Acquisition, the Company assumed such outstanding guarantees or similar obligations. As a result, as of December 31, 2011 and 2010, the Company had outstanding guarantees or similar obligations totaling $0.8 million.

        Further in the ordinary course of business, we may sell certain of our investments to third party purchasers. In particular, since the Allied Acquisition we have sold and currently continue to seek opportunities to sell certain of Allied Capital's equity investments larger than those we have historically made and controlled portfolio company equity investments. In connection with these sales (as well as certain other sales) we have, and may continue to do so in the future, agreed to indemnify such purchasers for future liabilities arising from the investments and the related sale transaction. Such indemnification provisions may give rise to future liabilities.

        As of December 31, 2011, one of the Company's portfolio companies, Ciena Capital LLC ("Ciena"), had one non-recourse securitization Small Business Administration ("SBA") loan warehouse facility, which has reached its maturity date but remains outstanding. Ciena is working with the providers of the SBA loan warehouse facility with regard to the repayment of that facility. Allied Capital had previously issued a performance guaranty (which Ares Capital succeeded to as a result of the Allied Acquisition) whereby Ares Capital must indemnify the warehouse providers for any damages, losses, liabilities and related costs and expenses that they may incur as a result of Ciena's failure to perform any of its obligations as loan originator, loan seller or loan servicer under the warehouse facility. As of December 31, 2011, there are no known issues or claims with respect to this performance guaranty.

RECENT DEVELOPMENTS

        In January 2012, Ares Capital and Ares Capital CP amended the Revolving Funding Facility to, among other things, (i) extend the reinvestment period by one year to January 18, 2015, (ii) extend the maturity date by one year to January 18, 2017, and (iii) replace the pricing grid with an applicable spread over LIBOR of 2.50% and an applicable spread over "base rate" of 1.50%.

        In January 2012, we established, through our wholly owned subsidiary ACJB LLC, the SMBC Funding Facility by entering into a Loan and Servicing Agreement (the "SMBC Loan and Servicing Agreement") with ACJB LLC, as the borrower, SMBC, as the administrative agent, collateral agent, and lender, pursuant to which SMBC has agreed to extend credit to ACJB LLC in an aggregate

85

---

principal amount up to $200 million at any one time outstanding. In connection with the SMBC Funding Facility, we entered into a Purchase and Sale Agreement with ACJB LLC, pursuant to which we may sell ACJB LLC certain first lien loans we have originated or acquired, or will originate or acquire (the "SMBC Loans") from time to time. The SMBC Funding Facility is a revolving funding facility with a reinvestment period ending January 20, 2015 and a final maturity date of January 20, 2020. The reinvestment period and final maturity are both subject to two one-year extensions by mutual agreement. Subject to certain exceptions, the interest rate charged on the SMBC Funding Facility is based on LIBOR plus 2.125% (with no floor) or a "base rate" (which is the greater of a prime rate and the federal funds rate plus 0.50%) plus 1.125% (with no floor). The SMBC Loan and Servicing Agreement includes usual and customary events of default for revolving funding facilities of this nature, including allowing SMBC, upon a default, to accelerate and foreclose on the SMBC Loans and to pursue the rights under the SMBC Loans directly with the obligors thereof.

        In January 2012, we completed a public add-on equity offering (the "January 2012 Offering") pursuant to which we sold 16.4 million shares of common stock at a net price of $15.41 per share. Total proceeds from the January 2012 Offering, net of underwriting discounts and commissions and estimated offering expenses payable by us, were approximately $252.5 million.

        In February 2012, we issued $143.8 million in aggregate principal amount of the 2022 Notes. The 2022 Notes mature on February 15, 2022 and may be redeemed in whole or in part at any time or from time to time at our option on or after February 15, 2015 at a par redemption price of $25 per security plus accrued and unpaid interest. The principal amount of the 2022 Notes will be payable at maturity. The 2022 Notes bear interest at a rate of 7.00% per year payable quarterly commencing on May 15, 2012. Total proceeds from the issuance of the 2022 Notes, net of underwriting discounts and offering costs, were approximately $138 million.

        We used the net proceeds of the January 2012 Offering and the issuance of the 2022 Notes to repay outstanding indebtedness under the Revolving Credit Facility and the Revolving Funding Facility.

        From January 1, 2012 through February 24, 2012, we had made new investment commitments of $190 million, of which $146 million were funded. Of these new commitments, 85% were in first lien senior secured debt and 15% were investments in subordinated certificates of the SSLP which were applied to co-investments with GE in senior secured loans. Of the $190 million of new investment commitments, all were floating rate. The weighted average yield of debt and income producing securities funded during the period at amortized cost was 10.3%. We may seek to syndicate a portion of these new investment commitments to third parties, although there can be no assurance that we will be able to do so.

        From January 1, 2012 through February 24, 2012, we exited $226 million of investment commitments. Of these investment commitments, 97% were in first lien senior secured debt and 3% were in equity and other securities. Of the $226 million of exited investment commitments, 97% were floating rate investments and 3% were non-interest bearing. The weighted average yield of debt and income producing securities exited or repaid during the period at amortized cost was 7.6%. On the $226 million of investment commitments exited from January 1, 2012 through February 24, 2012, we recognized total net realized losses of approximately $7 million. Included within the $226 million of investment commitments exited from January 1, 2012 through February 24, 2012 were $0.3 million of investment commitments acquired as part of the Allied Acquisition. We recognized no realized gains or losses on the investments exited that were acquired as part of the Allied Acquisition.

        In addition, as of February 24, 2012, we had an investment backlog and pipeline of approximately $280 million and $700 million, respectively. The consummation of any of the investments in this backlog and pipeline depends upon, among other things, one or more of the following: satisfactory completion of our due diligence investigation of the prospective portfolio company, our acceptance of the terms and structure of such investment and the execution and delivery of satisfactory transaction

documentation. In addition, we may syndicate a portion of these investments to third parties. We cannot assure you that we will make any of these investments or that we will syndicate any portion of these investments.

CRITICAL ACCOUNTING POLICIES

Basis of Presentation

        The accompanying consolidated financial statements have been prepared on the accrual basis of accounting in conformity with GAAP, and include the accounts of the Company and its wholly owned subsidiaries. The consolidated financial statements reflect all adjustments and reclassifications that, in the opinion of management, are necessary for the fair presentation of the results of the operations and financial condition as of and for the periods presented. All significant intercompany balances and transactions have been eliminated.

Cash and Cash Equivalents

        Cash and cash equivalents include funds from time to time deposited with financial institutions and short-term, liquid investments in a money market fund. Cash and cash equivalents are carried at cost which approximates fair value.

Concentration of Credit Risk

        The Company places its cash and cash equivalents with financial institutions and, at times, cash held in money market accounts may exceed the Federal Deposit Insurance Corporation insured limit.

Investments

        Investment transactions are recorded on the trade date. Realized gains or losses are measured by the difference between the net proceeds from the repayment or sale and the amortized cost basis of the investment without regard to unrealized gains or losses previously recognized, and include investments charged off during the period, net of recoveries. Unrealized gains or losses primarily reflect the change in investment values, including the reversal of previously recorded unrealized gains or losses when gains or losses are realized. Investments for which market quotations are readily available are typically valued at such market quotations. In order to validate market quotations, we look at a number of factors to determine if the quotations are representative of fair value, including the source and nature of the quotations. Debt and equity securities that are not publicly traded or whose market prices are not readily available (i.e., substantially all of our investments) are valued at fair value as determined in good faith by our board of directors, based on, among other things, the input of our investment adviser, audit committee and independent third-party valuation firms that have been engaged at the direction of our board of directors to assist in the valuation of each portfolio investment without a readily available market quotation at least once during a trailing 12 month period, and under a valuation policy and a consistently applied valuation process. The valuation process is conducted at the end of each fiscal quarter, and a minimum of 50% of our portfolio at fair value is subject to review by an independent valuation firm each quarter. In addition, our independent accountants review our valuation process as part of their overall integrated audit.

        As part of the valuation process, we may take into account the following types of factors, if relevant, in determining the fair value of our investments: the enterprise value of a portfolio company (an estimate of the total fair value of the portfolio company's debt and equity), the nature and realizable value of any collateral, the portfolio company's ability to make payments and its earnings and discounted cash flow, the markets in which the portfolio company does business, a comparison of the portfolio company's securities to any similar publicly traded securities, changes in the interest rate environment and the credit markets generally that may affect the price at which similar investments

87

---

may be made in the future and other relevant factors. When an external event such as a purchase transaction, public offering or subsequent equity sale occurs, we consider the pricing indicated by the external event to corroborate our valuation.

        Because there is not a readily available market value for most of the investments in our portfolio, we value substantially all of our portfolio investments at fair value as determined in good faith by our board of directors, as described herein. Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the fair value of our investments may fluctuate from period to period. Additionally, the fair value of our investments may differ significantly from the values that would have been used had a ready market existed for such investments and may differ materially from the values that we may ultimately realize. Further, such investments are generally subject to legal and other restrictions on resale or otherwise are less liquid than publicly traded securities. If we were required to liquidate a portfolio investment in a forced or liquidation sale, we could realize significantly less than the value at which we have recorded it.

        In addition, changes in the market environment and other events that may occur over the life of the investments may cause the gains or losses ultimately realized on these investments to be different than the gains or losses reflected in the valuations currently assigned.

        Our board of directors undertakes a multi-step valuation process each quarter, as described below:

•

Our quarterly valuation process begins with each portfolio company or investment being initially valued by the investment professionals responsible for the portfolio investment in conjunction with our portfolio management team.



•

Preliminary valuations are reviewed and discussed with our investment adviser's management and investment professionals, and then valuation recommendations are presented to our board of directors.



•

The audit committee of our board of directors reviews these valuations, as well as the input of third parties, including independent third-party valuation firms, with respect to the valuations of a minimum of 50% of our portfolio at fair value.



•

Our board of directors discusses valuations and determines the fair value of each investment in our portfolio without a readily available market quotation in good faith based on, among other things, the input of our investment adviser, audit committee and, where applicable, independent third-party valuation firms.

        Effective January 1, 2008, the Company adopted ASC 820-10 (previously SFAS No. 157, Fair Value Measurements), which expands the application of fair value accounting for investments (see Note 8 to the Company's consolidated financial statements for year ended December 31, 2011). Investments acquired as part of the Allied Acquisition were accounted for in accordance with ASC 805-10 (previously SFAS No. 141(R), Business Combinations), which requires that all assets be recorded at fair value. As a result, the initial amortized cost basis and fair value for the acquired investments were the same at April 1, 2010 (see Note 17 to the Company's consolidated financial statements for the year ended December 31, 2011).

Interest and Dividend Income Recognition

        Interest income is recorded on an accrual basis and includes the accretion of discounts and amortization of premiums. Discounts from and premiums to par value on securities purchased are accreted/amortized into interest income over the life of the respective security using the effective yield method. The amortized cost of investments represents the original cost adjusted for the accretion of discounts and amortization of premiums, if any.

88

---

        Loans are generally placed on non-accrual status when principal or interest payments are past due 30 days or more or when there is reasonable doubt that principal or interest will be collected in full. Accrued and unpaid interest is generally reversed when a loan is placed on non-accrual status. Interest payments received on non-accrual loans may be recognized as income or applied to principal depending upon management's judgment regarding collectability. Non-accrual loans are restored to accrual status when past due principal and interest is paid and, in management's judgment, are likely to remain current. The Company may make exceptions to this if the loan has sufficient collateral value and is in the process of collection.

        Dividend income on preferred equity securities is recorded as dividend income on an accrual basis to the extent that such amounts are payable by the portfolio company and are expected to be collected. Dividend income on common equity securities is recorded on the record date for private portfolio companies or on the ex-dividend date for publicly traded portfolio companies.

Payment-in-Kind Interest

        The Company has loans in its portfolio that contain PIK provisions. The PIK interest, computed at the contractual rate specified in each loan agreement, is added to the principal balance of the loan and recorded as interest income. To maintain the Company's status as a RIC, this non-cash source of income must be paid out to stockholders in the form of dividends even though the Company has not yet collected the cash.

Capital Structuring Service Fees and Other Income

        The Company's investment adviser seeks to provide assistance to our portfolio companies in connection with the Company's investments and in return the Company may receive fees for capital structuring services. These fees are generally only available to the Company as a result of the Company's underlying investments, are normally paid at the closing of the investments, are generally non-recurring and are recognized as revenue when earned upon closing of the investment. The services that the Company's investment adviser provides vary by investment, but generally include reviewing existing credit facilities, arranging bank financing, arranging equity financing, structuring financing from multiple lenders, structuring financing from multiple equity investors, restructuring existing loans, raising equity and debt capital, and providing general financial advice, which concludes upon closing of the investment. Any services of the above nature subsequent to the closing would generally generate a separate fee payable to the Company. In certain instances where the Company is invited to participate as a co-lender in a transaction and does not provide significant services in connection with the investment, a portion of loan fees paid to the Company in such situations will be deferred and amortized over the estimated life of the loan. The Company's investment adviser may also take a seat on the board of directors of a portfolio company, or observe the meetings of the board of directors without taking a formal seat.

        Other income includes fees for asset management, management and consulting services, loan guarantees, commitments, amendments and other services rendered by the Company to portfolio companies. Such fees are recognized as income when earned or the services are rendered.

Foreign Currency Translation

        The Company's books and records are maintained in U.S. dollars. Any foreign currency amounts are translated into U.S. dollars on the following basis:

(1)

Fair value of investment securities, other assets and liabilities—at the exchange rates prevailing at the end of the period.



(2)

Purchases and sales of investment securities, income and expenses—at the exchange rates prevailing on the respective dates of such transactions, income or expenses.

89

---

        Results of operations based on changes in foreign exchange rates are separately disclosed in the statement of operations. Foreign security and currency translations may involve certain considerations and risks not typically associated with investing in U.S. companies and U.S. government securities. These risks include, but are not limited to, currency fluctuation and revaluations and future adverse political, social and economic developments, which could cause investments in foreign markets to be less liquid and prices more volatile than those of comparable U.S. companies or U.S. government securities.

Accounting for Derivative Instruments

        The Company does not utilize hedge accounting and marks its derivatives to market through unrealized gains (losses) in the accompanying statement of operations.

Equity Offering Expenses

        The Company's offering costs, excluding underwriters' fees, are charged against the proceeds from equity offerings when received.

Debt Issuance Costs

        Debt issuance costs are amortized over the life of the related debt instrument using the straight line method, which closely approximates the effective yield method.

U.S. Federal Income Taxes

        The Company has elected to be treated as a RIC under Subchapter M of the Code and operates in a manner so as to qualify for the tax treatment applicable to RICs. To qualify as a RIC, the Company must, among other things, timely distribute to its stockholders at least 90% of its investment company taxable income, as defined by the Code, for each year. The Company, among other things, has made and intends to continue to make the requisite distributions to its stockholders, which will generally relieve the Company from U.S. federal income taxes.

        Depending on the level of taxable income earned in a tax year, we may choose to carry forward taxable income in excess of current year dividend distributions from such income into the next tax year and pay a 4% excise tax on such income, as required. To the extent that the Company determines that its estimated current year annual taxable income will be in excess of estimated current year dividend distributions, the Company accrues excise tax, if any, on estimated excess taxable income as such taxable income is earned.

        Certain of our wholly owned subsidiaries are subject to U.S. federal and state income taxes.

Dividends to Common Stockholders

        Dividends and distributions to common stockholders are recorded on the ex-dividend date. The amount to be paid out as a dividend is determined by our board of directors each quarter and is generally based upon the earnings estimated by management. Net realized capital gains, if any, are generally distributed at least annually, although we may decide to retain such capital gains for investment.

        We have adopted a dividend reinvestment plan that provides for reinvestment of any distributions we declare in cash on behalf of our stockholders, unless a stockholder elects to receive cash. As a result, if our board of directors authorizes, and we declare, a cash dividend, then our stockholders who have not "opted out" of our dividend reinvestment plan will have their cash dividends automatically reinvested in additional shares of our common stock, rather than receiving the cash dividend. While we generally use newly issued shares to implement the dividend reinvestment plan (especially if our shares

90

---

are trading at a premium to net asset value), we may purchase shares in the open market in connection with our obligations under the dividend reinvestment plan. In particular, if our shares are trading at a significant enough discount to net asset value and we are otherwise permitted under applicable law to purchase such shares, we intend to purchase shares in the open market in connection with our obligations under our dividend reinvestment plan.

Use of Estimates in the Preparation of Financial Statements

        The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of actual and contingent assets and liabilities at the date of the financial statements and the reported amounts of income or loss and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates include the valuation of investments.

Item 7A.    Quantitative and Qualitative Disclosures About Market Risk

        We are subject to financial market risks, including changes in interest rates and the valuations of our investment portfolio.

Interest Rate Risk

        Interest rate sensitivity refers to the change in earnings that may result from changes in the level of interest rates. Because we fund a portion of our investments with borrowings, our net investment income is affected by the difference between the rate at which we invest and the rate at which we borrow. As a result, there can be no assurance that a significant change in market interest rates will not have a material adverse effect on our net investment income. See "Risk Factors—We are exposed to risks associated with changes in interest rates."

        As of December 31, 2011, approximately 20% of the investments at fair value in our portfolio were at fixed rates, approximately 67% were at variable rates, 12% were non-interest earning and 1% were on non-accrual status. Additionally, for the investments at variable rates, 64% of the investments contain interest rate floors (representing 43% of total investments at fair value). The Revolving Credit Facility, the Revolving Funding Facility, the SMBC Funding Facility and the Debt Securitization all bear interest at variable rates with no interest rate floors, while the 2022 Notes, 2040 Notes, 2047 Notes and Convertible Notes bear interest at fixed rates.

        We regularly measure our exposure to interest rate risk. We assess interest rate risk and manage our interest rate exposure on an ongoing basis by comparing our interest rate sensitive assets to our interest rate sensitive liabilities. Based on that review, we determine whether or not any hedging transactions are necessary to mitigate exposure to changes in interest rates.

        While hedging activities may mitigate our exposure to adverse fluctuations in interest rates, certain hedging transactions that we may enter into in the future, such as interest rate swap agreements, may also limit our ability to participate in the benefits of lower interest rates with respect to our portfolio investments. In addition, there can be no assurance that we will be able to effectively hedge our interest rate risk.

Item 9A.    Controls And Procedures

        (a)    Evaluation of Disclosure Controls and Procedures.    The Company's management, with the participation of the Company's President and Chief Financial Officer, has evaluated the effectiveness of the Company's disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act) as of the end of the period covered by this report. Based upon such evaluation, the Company's President and Chief Financial Officer concluded that our disclosure controls and procedures were effective, as of December 31, 2011, to provide assurance that information that is required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized, and reported, within the time periods specified by the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company's management, including its Chief Executive Officer and Chief Financial Officer, or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure.

        (b)    Management's Report on Internal Control over Financial Reporting.    The Company's management is responsible for establishing and maintaining adequate internal controls over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act).

Company conducted an evaluation of the effectiveness of the Company's internal controls over financial reporting based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on the Company's evaluation under the framework in Internal Control—Integrated Framework, management concluded that the Company's internal controls over financial reporting was effective as of December 31, 2011. The Company's internal controls over financial reporting as of December 31, 2011, has been audited by our independent registered public accounting firm, KPMG LLP, as stated in its report titled "Report of Independent Registered Public Accounting Firm" on page F-2.

        Because of its inherent limitations, internal controls over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders
Ares Capital Corporation

        We have audited the accompanying consolidated balance sheet of Ares Capital Corporation (and subsidiaries) (the Company) as of December 31, 2011 and 2010, including the consolidated schedules of investments as of December 31, 2011 and 2010, and the related consolidated statements of operations, stockholders' equity, and cash flows, and the financial highlights (included in Note 15), for each of the years in the three-year period ended December 31, 2011. These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

        We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

        In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Ares Capital Corporation (and subsidiaries) as of December 31, 2011 and 2010, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2011, in conformity with U.S. generally accepted accounting principles.

        We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Ares Capital Corporation's internal control over financial reporting as of December 31, 2011, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of Treadway Commission (COSO), and our report dated February 27, 2012 expressed an unqualified opinion on the effectiveness of Ares Capital Corporation's internal control over financial reporting.

        As explained in Note 8 to the consolidated financial statements, the accompanying consolidated financial statements include investments valued at $5.1 billion (162% of net assets), whose fair values have been estimated by the Board of Directors and management in the absence of readily determinable fair values. Such estimates are based on financial and other information provided by management of its portfolio companies, pertinent market and industry data, as well as input from independent valuation firms. These investments are valued in accordance with FASB ASC 820, Fair Value Measurements and Disclosures, which requires the Company to assume that the portfolio investments are sold in a principal market to market participants. The Company has considered its principal market as the market in which the Company exits its portfolio investments with the greatest volume and level of activity. ASC 820 specifies a hierarchy of valuation techniques based on whether the inputs to these valuation techniques are observable or unobservable. $5.1 billion of investments at December 31, 2011 are valued based on unobservable inputs. Because such valuations, and particularly valuations of private investments and private companies, are inherently uncertain, they may fluctuate significantly over short periods of time. These determinations of fair value could differ materially from the values that would have been utilized had a ready market for these investments existed.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders
Ares Capital Corporation:

        We have audited Ares Capital Corporation's (the Company) internal control over financial reporting as of December 31, 2011, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Ares Capital Corporation's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

        We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

        A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

        Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

        In our opinion, Ares Capital Corporation maintained, in all material respects, effective internal control over financial reporting as of December 31, 2011, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Other than our investments listed in footnote 7 below, we do not "Control" any of our portfolio companies, as defined in the Investment Company Act of 1940, as amended (together with the rules and regulations promulgated thereunder, the "Investment Company Act"). In general, under the Investment Company Act, we would "Control" a portfolio company if we owned more than 25% of its outstanding voting securities and/or had the power to exercise control over the management or policies of such portfolio company. All of our portfolio company investments, which as of December 31, 2011 represented 162% of the Company's net assets or 95% of the Company's total assets, are subject to legal restrictions on sales.

The investments not otherwise pledged as collateral in respect of the Debt Securitization (as defined below) or the Revolving Funding Facility (as defined below) by the respective obligors thereunder are pledged as collateral by the Company and certain of its other subsidiaries for the Revolving Credit Facility (as defined below) (except for a limited number of exceptions as provided in the credit agreement governing the Revolving Credit Facility).

These assets are owned by the Company's wholly owned subsidiary Ares Capital CP Funding LLC ("Ares Capital CP"), are pledged as collateral for the Revolving Funding Facility and, as a result, are not directly available to the creditors of the Company to satisfy any obligations of the Company other than Ares Capital CP's obligations under the Revolving Funding Facility (see Note 5 to the consolidated financial statements).

Together with GE Global Sponsor Finance LLC and General Electric Capital Corporation (together, "GE"), we co-invest through the Senior Secured Loan Fund LLC d/b/a the "Senior Secured Loan Program" (the "SSLP"). The SSLP is capitalized as transactions are completed and all portfolio decisions and generally all other decisions in respect of the SSLP must be approved by GE and the Company; therefore, although the Company owns more than 25% of the voting securities of the SSLP, the Company does not believe that it has control over the SSLP (for purposes of the Investment Company Act or otherwise).

Non-U.S. company or principal place of business outside the U.S. and as a result is not a qualifying asset under Section 55(a) of the Investment Company Act. Under the Investment Company Act, we may not acquire any non-qualifying asset unless, at the time such acquisition is made, qualifying assets represent at least 70% of our total assets.

(9)

Excepted from the definition of investment company under Section 3(c) of the Investment Company Act and as a result is not a qualifying asset under Section 55(a) of the Investment Company Act. Under the Investment Company Act, we may not acquire any non-qualifying asset unless, at the time such acquisition is made, qualifying assets represent at least 70% of our total assets.

(10)

Public company with outstanding equity with a market value in excess of $250 million and as a result is not a qualifying asset under Section 55(a) of the Investment Company Act. Under the Investment Company Act, we may not acquire any non-qualifying asset unless, at the time such acquisition is made, qualifying assets represent at least 70% of our total assets.

(11)

In the first quarter of 2011, the staff of the Securities and Exchange Commission (the "Staff") informally communicated to certain business development companies the Staff's belief that certain entities, which would be classified as an "investment company" under the Investment Company Act but for the exception from the definition of "investment company" set forth in Rule 3a-7 promulgated under the Investment Company Act, could not be treated as eligible portfolio companies (as defined in Section 2(a)(46) of the Investment Company Act). Subsequently, in August 2011 the Securities and Exchange Commission issued a concept release (the "Concept Release") which states that "[a]s a general matter, the Commission presently does not believe that Rule 3a-7 issuers are the type of small, developing and financially troubled businesses in which Congress intended BDCs primarily to invest" and requested comment on whether or not a 3a-7 issuer should be considered an "eligible portfolio company". Ares Capital continues to believe that the language of Section 2(a)(46) of the Investment Company Act permits a business development company to treat as "eligible portfolio companies" entities that rely on the 3a-7 exception. However, given the current uncertainty in this area (including the language in the Concept Release), Ares Capital has, solely for purposes of calculating the composition of its portfolio pursuant to Section 55(a) of the Investment Company Act, identified these entities in our schedule of investments as "non-qualifying assets" should the Staff ultimately disagree with Ares Capital's position.

(12)

Variable rate loans to our portfolio companies bear interest at a rate that may be determined by reference to either LIBOR or an alternate base rate (commonly based on the Federal Funds Rate or the Prime Rate), at the borrower's option, which reset annually (A), semi-annually (S), quarterly (Q), bi-monthly (B), monthly (M) or daily (D). For each such loan, we have provided the interest rate in effect on the date presented.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
As of December 31, 2011
(in thousands, except per share data, percentages and as otherwise indicated;
for example, with the words "million," "billion" or otherwise)

1.     ORGANIZATION

        Ares Capital Corporation (the "Company" or "ARCC" or "we") is a specialty finance company that is a closed-end, non-diversified management investment company incorporated in Maryland. We have elected to be regulated as a business development company under the Investment Company Act of 1940, as amended (together with the rules and regulations promulgated thereunder, the "Investment Company Act"). We were incorporated on April 16, 2004 and were initially funded on June 23, 2004. On October 8, 2004, we completed our initial public offering. On the same date, we commenced substantial investment operations.

        On April 1, 2010, we consummated our acquisition of Allied Capital Corporation ("Allied Capital"), in an all stock merger where each existing share of common stock of Allied Capital was exchanged for 0.325 shares of our common stock (the "Allied Acquisition"). The Allied Acquisition was valued at approximately $908 million as of April 1, 2010. In connection therewith, we issued approximately 58.5 million shares of our common stock to Allied Capital's then-existing stockholders, thereby resulting in our then-existing stockholders owning approximately 69% of the combined company and then-existing Allied Capital stockholders owning approximately 31% of the combined company (see Note 17).

        The Company has elected to be treated as a regulated investment company, or a "RIC", under Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code") and operates in a manner so as to qualify for the tax treatment applicable to RICs. Our investment objective is to generate both current income and capital appreciation through debt and equity investments. We invest primarily in first and second lien senior loans and mezzanine debt, which in some cases includes an equity component. To a lesser extent, we also make equity investments. Also, as a result of the Allied Acquisition, Allied Capital's equity investments, including equity investments larger than those we have historically made and controlled portfolio company equity investments, became part of our portfolio.

        We are externally managed by Ares Capital Management LLC ("Ares Capital Management" or our "investment adviser"), a wholly owned subsidiary of Ares Management LLC ("Ares Management"), a global alternative asset manager and a Securities and Exchange Commission ("SEC") registered investment adviser. Ares Operations LLC ("Ares Operations" or our "administrator"), a wholly owned subsidiary of Ares Management, provides the administrative services necessary for us to operate.

2.     SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

        The accompanying consolidated financial statements have been prepared on the accrual basis of accounting in conformity with GAAP, and include the accounts of the Company and its wholly owned subsidiaries. The consolidated financial statements reflect all adjustments and reclassifications that, in the opinion of management, are necessary for the fair presentation of the results of the operations and financial condition as of and for the periods presented. All significant intercompany balances and transactions have been eliminated.

F-49

---

Cash and Cash Equivalents

        Cash and cash equivalents include funds from time to time deposited with financial institutions and short-term, liquid investments in a money market fund. Cash and cash equivalents are carried at cost which approximates fair value.

Concentration of Credit Risk

        The Company places its cash and cash equivalents with financial institutions and, at times, cash held in money market accounts may exceed the Federal Deposit Insurance Corporation insured limit.

Investments

        Investment transactions are recorded on the trade date. Realized gains or losses are measured by the difference between the net proceeds from the repayment or sale and the amortized cost basis of the investment without regard to unrealized gains or losses previously recognized, and include investments charged off during the period, net of recoveries. Unrealized gains or losses primarily reflect the change in investment values, including the reversal of previously recorded unrealized gains or losses when gains or losses are realized.

        Investments for which market quotations are readily available are typically valued at such market quotations. In order to validate market quotations, we look at a number of factors to determine if the quotations are representative of fair value, including the source and nature of the quotations. Debt and equity securities that are not publicly traded or whose market prices are not readily available (i.e., substantially all of our investments) are valued at fair value as determined in good faith by our board of directors, based on, among other things, the input of our investment adviser, audit committee and independent third-party valuation firms that have been engaged at the direction of our board of directors to assist in the valuation of each portfolio investment without a readily available market quotation at least once during a trailing 12 month period and under a valuation policy and a consistently applied valuation process. The valuation process is conducted at the end of each fiscal quarter, and a minimum of 50% of our portfolio at fair value is subject to review by an independent valuation firm each quarter. In addition, our independent accountants review our valuation process as part of their overall integrated audit.

        As part of the valuation process, we may take into account the following types of factors, if relevant, in determining the fair value of our investments: the enterprise value of a portfolio company (an estimate of the total fair value of the portfolio company's debt and equity), the nature and realizable value of any collateral, the portfolio company's ability to make payments and its earnings and discounted cash flow, the markets in which the portfolio company does business, a comparison of the portfolio company's securities to any similar publicly traded securities, changes in the interest rate environment and the credit markets generally that may affect the price at which similar investments may be made in the future and other relevant factors. When an external event such as a purchase transaction, public offering or subsequent equity sale occurs, we consider the pricing indicated by the external event to corroborate our valuation.

        Because there is not a readily available market value for most of the investments in our portfolio, we value substantially all of our portfolio investments at fair value as determined in good faith by our board of directors, as described herein. Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the fair value of our investments may fluctuate from period to period. Additionally, the fair value of our investments may differ significantly from the values that would have been used had a ready market existed for such investments and may differ materially from the values that we may ultimately realize. Further, such investments are generally subject to legal and other restrictions on resale or otherwise are less liquid than publicly traded

F-50

---

securities. If we were required to liquidate a portfolio investment in a forced or liquidation sale, we could realize significantly less than the value at which we have recorded it.

        In addition, changes in the market environment and other events that may occur over the life of the investments may cause the gains or losses ultimately realized on these investments to be different than the gains or losses reflected in the valuations currently assigned.

        Our board of directors undertakes a multi-step valuation process each quarter, as described below:

•

Our quarterly valuation process begins with each portfolio company or investment being initially valued by the investment professionals responsible for the portfolio investment in conjunction with our portfolio management team.



•

Preliminary valuations are reviewed and discussed with our investment adviser's management and investment professionals, and then valuation recommendations are presented to our board of directors.



•

The audit committee of our board of directors reviews these valuations, as well as the input of third parties, including independent third-party valuation firms, with respect to the valuations of a minimum of 50% of our portfolio at fair value.



•

Our board of directors discusses valuations and determines the fair value of each investment in our portfolio without a readily available market quotation in good faith based on, among other things, the input of our investment adviser, audit committee and, where applicable, independent third-party valuation firms.

        Effective January 1, 2008, the Company adopted Accounting Standards Codification ("ASC") 820-10 (previously Statement of Financial Accounting Standards ("SFAS") No. 157, Fair Value Measurements), which expands the application of fair value accounting for investments (see Note 8). Investments acquired as part of the Allied Acquisition were accounted for in accordance with ASC 805-10 (previously SFAS No. 141(R), Business Combinations), which requires that all assets be recorded at fair value. As a result, the initial amortized cost basis and fair value for the acquired investments were the same at April 1, 2010 (see Note 17).

Interest and Dividend Income Recognition

        Interest income is recorded on an accrual basis and includes the accretion of discounts and amortization of premiums. Discounts from and premiums to par value on securities purchased are accreted/amortized into interest income over the life of the respective security using the effective yield method. The amortized cost of investments represents the original cost adjusted for the accretion of discounts and amortization of premiums, if any.

        Loans are generally placed on non-accrual status when principal or interest payments are past due 30 days or more or when there is reasonable doubt that principal or interest will be collected in full. Accrued and unpaid interest is generally reversed when a loan is placed on non-accrual status. Interest payments received on non-accrual loans may be recognized as income or applied to principal depending upon management's judgment regarding collectability. Non-accrual loans are restored to accrual status when past due principal and interest is paid and, in management's judgment, are likely to remain current. The Company may make exceptions to this if the loan has sufficient collateral value and is in the process of collection.

        Dividend income on preferred equity securities is recorded as dividend income on an accrual basis to the extent that such amounts are payable by the portfolio company and are expected to be collected. Dividend income on common equity securities is recorded on the record date for private portfolio companies or on the ex-dividend date for publicly traded portfolio companies.

F-51

---

Payment-in-Kind Interest

        The Company has loans in its portfolio that contain payment-in-kind ("PIK") provisions. The PIK interest, computed at the contractual rate specified in each loan agreement, is added to the principal balance of the loan and recorded as interest income. To maintain the Company's status as a RIC, this non-cash source of income must be paid out to stockholders in the form of dividends, even though the Company has not yet collected the cash.

Capital Structuring Service Fees and Other Income

        The Company's investment adviser seeks to provide assistance to our portfolio companies in connection with the Company's investments and in return the Company may receive fees for capital structuring services. These fees are generally only available to the Company as a result of the Company's underlying investments, are normally paid at the closing of the investments, are generally non-recurring and are recognized as revenue when earned upon closing of the investment. The services that the Company's investment adviser provides vary by investment, but generally include reviewing existing credit facilities, arranging bank financing, arranging equity financing, structuring financing from multiple lenders, structuring financing from multiple equity investors, restructuring existing loans, raising equity and debt capital, and providing general financial advice, which concludes upon closing of the investment. Any services of the above nature subsequent to the closing would generally generate a separate fee payable to the Company. In certain instances where the Company is invited to participate as a co-lender in a transaction and does not provide significant services in connection with the investment, a portion of loan fees paid to the Company in such situations will be deferred and amortized over the estimated life of the loan. The Company's investment adviser may also take a seat on the board of directors of a portfolio company, or observe the meetings of the board of directors without taking a formal seat.

        Other income includes fees for asset management, management and consulting services, loan guarantees, commitments, amendments and other services rendered by the Company to portfolio companies. Such fees are recognized as income when earned or the services are rendered.

Foreign Currency Translation

        The Company's books and records are maintained in U.S. dollars. Any foreign currency amounts are translated into U.S. dollars on the following basis:

(1)

Fair value of investment securities, other assets and liabilities—at the exchange rates prevailing at the end of the period.



(2)

Purchases and sales of investment securities, income and expenses—at the exchange rates prevailing on the respective dates of such transactions, income or expenses.

        Results of operations based on changes in foreign exchange rates are separately disclosed in the statement of operations. Foreign security and currency translations may involve certain considerations and risks not typically associated with investing in U.S. companies and U.S. government securities. These risks include, but are not limited to, currency fluctuation and revaluations and future adverse political, social and economic developments, which could cause investments in foreign markets to be less liquid and prices more volatile than those of comparable U.S. companies or U.S. government securities.

Accounting for Derivative Instruments

        The Company does not utilize hedge accounting and marks its derivatives to market through unrealized gains (losses) in the accompanying statement of operations.

F-52

---

Equity Offering Expenses

        The Company's offering costs, excluding underwriters' fees, are charged against the proceeds from equity offerings when received.

Debt Issuance Costs

        Debt issuance costs are amortized over the life of the related debt instrument using the straight line method, which closely approximates the effective yield method.

U.S. Federal Income Taxes

        The Company has elected to be treated as a RIC under Subchapter M of the Code and operates in a manner so as to qualify for the tax treatment applicable to RICs. To qualify as a RIC, the Company must, among other things, timely distribute to its stockholders at least 90% of its investment company taxable income, as defined by the Code, for each year. The Company, among other things, has made and intends to continue to make the requisite distributions to its stockholders, which will generally relieve the Company from U.S. federal income taxes.

        Depending on the level of taxable income earned in a tax year, we may choose to carry forward taxable income in excess of current year dividend distributions from such income into the next tax year and pay a 4% excise tax on such income, as required. To the extent that the Company determines that its estimated current year annual taxable income will be in excess of estimated current year dividend distributions, the Company accrues excise tax, if any, on estimated excess taxable income as such taxable income is earned.

Dividends to Common Stockholders

        Dividends and distributions to common stockholders are recorded on the ex-dividend date. The amount to be paid out as a dividend is determined by our board of directors each quarter and is generally based upon the earnings estimated by management. Net realized capital gains, if any, are generally distributed at least annually, although we may decide to retain such capital gains for investment.

        We have adopted a dividend reinvestment plan that provides for reinvestment of any distributions we declare in cash on behalf of our stockholders, unless a stockholder elects to receive cash. As a result, if our board of directors authorizes, and we declare, a cash dividend, then our stockholders who have not "opted out" of our dividend reinvestment plan will have their cash dividends automatically reinvested in additional shares of our common stock, rather than receiving the cash dividend. While we generally use newly issued shares to implement the dividend reinvestment plan (especially if our shares are trading at a premium to net asset value), we may purchase shares in the open market in connection with our obligations under the dividend reinvestment plan. In particular, if our shares are trading at a significant enough discount to net asset value and we are otherwise permitted under applicable law to purchase such shares, we intend to purchase shares in the open market in connection with our obligations under our dividend reinvestment plan.

Use of Estimates in the Preparation of Financial Statements

        The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of actual and contingent assets and liabilities at the date of the financial statements and the reported amounts of income or loss and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates include the valuation of investments.

New Accounting Pronouncements

        In May 2011, the Financial Accounting Standards Board issued Accounting Standards Update ("ASU") 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs ("ASU 2011-04"). ASU 2011-04 was issued concurrently with International Financial Reporting Standards No.13 ("IFRS 13"), Fair Value Measurements, to provide largely identical guidance about fair value measurement and disclosure requirements as is currently required under ASU 2010-06, Fair Value Measurements and Disclosures (Topic 820). The new standards do not extend the use of fair value but, rather, provide guidance about how fair value should be applied where it already is required or permitted under IFRS or GAAP. For GAAP, most of the changes are clarifications of existing guidance or wording changes to align with IFRS 13. ASU 2011-04 eliminates the concepts of in-use and in-exchange when measuring fair value of all financial instruments. For Level 3 fair value measurements, the ASU requires that our disclosure include quantitative information about significant unobservable inputs, a qualitative discussion about the sensitivity of the fair value measurement to changes in the unobservable inputs and the interrelationship between inputs, and a description of our valuation process. Public companies are required to apply ASU 2011-04 prospectively for interim and annual periods beginning after December 15, 2011. The Company is currently evaluating the impact of the adoption of ASU 2011-04 on its financial statements and disclosures.

3.     AGREEMENTS

Investment Advisory and Management Agreement

        The Company is party to an investment advisory and management agreement (the "investment advisory and management agreement") with Ares Capital Management. Subject to the overall supervision of our board of directors, Ares Capital Management provides investment advisory and management services to the Company. For providing these services, Ares Capital Management receives a fee from us consisting of two components—a base management fee and an incentive fee.

        The base management fee is calculated at an annual rate of 1.5% based on the average value of our total assets (other than cash or cash equivalents but including assets purchased with borrowed funds) at the end of the two most recently completed calendar quarters. The base management fee is payable quarterly in arrears.

        The incentive fee has two parts. The first part is calculated and payable quarterly in arrears based on our pre-incentive fee net investment income for the quarter. Pre-incentive fee net investment income means interest income, dividend income and any other income (including any other fees such as commitment, origination, structuring, diligence and consulting fees or other fees that we receive from portfolio companies but excluding fees for providing managerial assistance) accrued during the calendar quarter, minus operating expenses for the quarter (including the base management fee, any expenses payable under the administration agreement, and any interest expense and dividends paid on any outstanding preferred stock, but excluding the incentive fee). Pre-incentive fee net investment income includes, in the case of investments with a deferred interest feature such as market discount, debt instruments with PIK interest, preferred stock with PIK dividends and zero coupon securities, accrued income that we have not yet received in cash. Our investment adviser is not under any obligation to reimburse us for any part of the incentive fee it received that was based on accrued interest that we never actually receive.

        Pre-incentive fee net investment income does not include any realized capital gains, realized capital losses, unrealized capital appreciation, unrealized capital depreciation or income tax expense related to realized gains. Because of the structure of the incentive fee, it is possible that we may pay an incentive fee in a quarter where we incur a loss. For example, if we receive pre-incentive fee net investment income in excess of the hurdle rate (as defined below) for a quarter, we will pay the applicable

F-54

---

incentive fee even if we have incurred a loss in that quarter due to realized and/or unrealized capital losses.

        Pre-incentive fee net investment income, expressed as a rate of return on the value of our net assets (defined as total assets less indebtedness and before taking into account any incentive fees payable during the period) at the end of the immediately preceding calendar quarter, is compared to a fixed "hurdle rate" of 1.75% per quarter. If market credit spreads rise, we may be able to invest our funds in debt instruments that provide for a higher return, which may increase our pre-incentive fee net investment income and make it easier for our investment adviser to surpass the fixed hurdle rate and receive an incentive fee based on such net investment income. To the extent we have retained pre-incentive fee net investment income that has been used to calculate this part of the incentive fee, it is also included in the amount of our total assets (other than cash and cash equivalents but including assets purchased with borrowed funds) used to calculate the 1.5% base management fee.

        We pay our investment adviser an incentive fee with respect to our pre-incentive fee net investment income in each calendar quarter as follows:

•

no incentive fee in any calendar quarter in which our pre-incentive fee net investment income does not exceed the hurdle rate;



•

100% of our pre-incentive fee net investment income with respect to that portion of such pre-incentive fee net investment income, if any, that exceeds the hurdle rate but is less than 2.1875% in any calendar quarter. We refer to this portion of our pre-incentive fee net investment income (which exceeds the hurdle rate but is less than 2.1875%) as the "catch-up" provision. The "catch-up" is meant to provide our investment adviser with 20% of the pre-incentive fee net investment income as if a hurdle rate did not apply if this net investment income exceeded 2.1875% in any calendar quarter; and



•

20% of the amount of our pre-incentive fee net investment income, if any, that exceeds 2.1875% in any calendar quarter.

        These calculations are adjusted for any share issuances or repurchases during the quarter.

        The second part of the incentive fee (the "Capital Gains Fee"), is determined and payable in arrears as of the end of each calendar year (or, upon termination of the investment advisory and management agreement, as of the termination date) and is calculated at the end of each applicable year by subtracting (a) the sum of our cumulative aggregate realized capital losses and aggregate unrealized capital depreciation from (b) our cumulative aggregate realized capital gains, in each case calculated from October 8, 2004. Realized capital gains and losses include gains and losses on investments and foreign currencies, as well as gains and losses on extinguishment of debt and other assets. If such amount is positive at the end of such year, then the Capital Gains Fee for such year is equal to 20% of such amount, less the aggregate amount of Capital Gains Fees paid in all prior years. If such amount is negative, then there is no Capital Gains Fee for such year.

        The cumulative aggregate realized capital gains are calculated as the sum of the differences, if positive, between (a) the net sales price of each investment in our portfolio when sold and (b) the accreted or amortized cost basis of such investment.

        The cumulative aggregate realized capital losses are calculated as the sum of the amounts by which (a) the net sales price of each investment in our portfolio when sold is less than (b) the accreted or amortized cost basis of such investment.

        The aggregate unrealized capital depreciation is calculated as the sum of the differences, if negative, between (a) the valuation of each investment in our portfolio as of the applicable Capital Gains Fee calculation date and (b) the accreted or amortized cost basis of such investment.

        Notwithstanding the foregoing, as a result of an amendment to the capital gains portion of the incentive fee under the investment advisory and management agreement (the "Capital Gains Amendment") that was adopted on June 6, 2011, if we are required by GAAP to record an investment at its fair value as of the time of acquisition instead of at the actual amount paid for such investment by us (including, for example, as a result of the application of the acquisition method of accounting), then solely for the purposes of calculating the Capital Gains Fee, the "accreted or amortized cost basis" of an investment shall be an amount (the "Contractual Cost Basis") equal to (1) (x) the actual amount paid by the Company for such investment plus (y) any amounts recorded in the Company's financial statements as required by GAAP that are attributable to the accretion of such investment plus (z) any other adjustments made to the cost basis included in the Company's financial statements, including payment-in-kind interest or additional amounts funded (net of repayments) minus (2) any amounts recorded in the Company's financial statements as required by GAAP that are attributable to the amortization of such investment, whether such calculated Contractual Cost Basis is higher or lower than the fair value of such investment (as determined in accordance with GAAP) at the time of acquisition.

        We defer cash payment of any incentive fee otherwise earned by our investment adviser if during the most recent four full calendar quarter period ending on or prior to the date such payment is to be made the sum of (a) the aggregate distributions to our stockholders and (b) the change in net assets (defined as total assets less indebtedness and before taking into account any incentive fees payable during the period) is less than 7.0% of our net assets (defined as total assets less indebtedness) at the beginning of such period. Any deferred incentive fees are carried over for payment in subsequent calculation periods to the extent such payment is payable under the investment advisory and management agreement.

        The Capital Gains Fee due to our investment adviser as calculated under the investment advisory and management agreement (as described above) for the year ended December 31, 2011 was $0. However, in accordance with GAAP, for the year ended December 31, 2011, the Company recorded a capital gains incentive fee of $33,348, including $26,012 recognized in the second quarter of 2011 as a result of the application of the Capital Gains Amendment described above with respect to the assets purchased in the Allied Acquisition, bringing the total GAAP accrual related to the capital gains incentive fee to $48,957 as of December 31, 2011. GAAP requires that the capital gains incentive fee accrual consider the cumulative aggregate unrealized capital appreciation in the calculation, as a capital gains incentive fee would be payable if such unrealized capital appreciation were realized, even though such unrealized capital appreciation is not permitted to be considered in calculating the fee actually payable under the investment advisory and management agreement. This GAAP accrual is calculated using the aggregate cumulative realized capital gains and losses and aggregate cumulative unrealized capital depreciation included in the calculation of the Capital Gains Fee plus the aggregate cumulative unrealized capital appreciation. If such amount is positive at the end of a period, then GAAP requires us to record a capital gains incentive fee equal to 20% of such cumulative amount, less the aggregate amount of actual Capital Gains Fees paid or capital gains incentive fees accrued under GAAP in all prior periods. The resulting accrual for any capital gains incentive fee under GAAP in a given period may result in an additional expense if such cumulative amount is greater than in the prior period or a reversal of previously recorded expense if such cumulative amount is less than in the prior period. If such cumulative amount is negative, then there is no accrual. There can be no assurance that such unrealized capital appreciation will be realized in the future. Also for the year ended December 31, 2010, in accordance with GAAP, the Company recorded a capital gains incentive fee of $15,609. There was no similar GAAP expense for the year ended December 31, 2009.

        For the year ended December 31, 2011, base management fees were $71,603, incentive management fees related to pre-incentive fee net investment income were $79,029 and incentive management fees related to capital gains were $33,348. As of December 31, 2011, $92,496 was included

in "management and incentive fees payable" in the accompanying consolidated balance sheet, of which $43,539 is currently payable to the Company's investment adviser under the investment advisory and management agreement.

        For the year ended December 31, 2010, base management fees were $51,998, incentive management fees related to pre-incentive fee net investment income were $61,286 and incentive management fees related to capital gains were $15,609.

        For the year ended December 31, 2009, base management fees were $30,409, incentive management fees related to pre-incentive fee net investment income were $33,332 and there were no incentive management fees related to capital gains.

Administration Agreement

        We are party to a separate administration agreement, referred to herein as the "administration agreement", with our administrator, Ares Operations. Pursuant to the administration agreement, Ares Operations furnishes us with office equipment and clerical, bookkeeping and record keeping services at our office facilities. Under the administration agreement, Ares Operations also performs, or oversees the performance of, our required administrative services, which include, among other things, providing assistance in accounting, legal, compliance, operations, technology, and investor relations, being responsible for the financial records that we are required to maintain and preparing reports to our stockholders and reports filed with the SEC. In addition, Ares Operations assists us in determining and publishing our net asset value, oversees the preparation and filing of our tax returns and the printing and dissemination of reports to our stockholders, and generally oversees the payment of our expenses and the performance of administrative and professional services rendered to us by others. Payments under our administration agreement are equal to an amount based upon our allocable portion of Ares Operations' overhead and other expenses (including travel expenses) incurred by Ares Operations in performing its obligations under the administration agreement, including our allocable portion of the compensation of certain of our officers (including our chief compliance officer, chief financial officer, general counsel, treasurer and assistant treasurer) and their respective staffs. The administration agreement may be terminated by either party without penalty upon 60 days' written notice to the other party.

        For the years ended December 31, 2011, 2010 and 2009, we incurred $9,317, $8,721 and $4,009, respectively, in administrative fees. As of December 31, 2011, $2,416 was unpaid and included in "accounts payable and accrued expenses" in the accompanying consolidated balance sheet.

        The industrial and geographic compositions of our portfolio at fair value at December 31, 2011 and December 31, 2010 were as follows:

        As of December 31, 2011, 3.3% of total investments at amortized cost (or 0.9% of total investments at fair value), were on non-accrual status, including 1.8% of total investments at amortized cost (or 0.6% of total investments at fair value) of investments acquired as part of the Allied Acquisition. As of December 31, 2010, 3.8% of total investments at amortized cost (or 1.3% of total investments at fair value), were on non-accrual status, including 1.5% of total investments at amortized cost (or 1.0% of total investments at fair value) of investments acquired as part of the Allied Acquisition.

SSLP

        In October 2009, the Company completed its acquisition from Allied Capital of subordinated certificates (the "SSLP Certificates") issued by the Senior Secured Loan Fund LLC, which operates using the name "Senior Secured Loan Program" (the "SSLP"), an unconsolidated vehicle. The SSLP was formed in December 2007 to co-invest in "stretch senior" and "unitranche" loans (loans that combine both senior and subordinated debt, generally in a first lien position) of middle-market companies with GE Global Sponsor Finance LLC and General Electric Capital Corporation (together, "GE"). The SSLP is capitalized as transactions are completed and all portfolio decisions and generally all other decisions in respect of the SSLP must be approved by both the Company and an affiliate of GE.

        As of December 31, 2011 and December 31, 2010, the SSLP had available capital of approximately $7.7 billion and $5.1 billion, respectively, approximately $5.0 billion and $2.5 billion in aggregate principal amount of which was funded at December 31, 2011 and 2010, respectively. At December 31, 2011, the Company had agreed to make available to the SSLP $1,487,500, of which $442,523 was unfunded. At December 31, 2010, the Company had agreed to make available to the SSLP $958,794, of which $410,633 was unfunded. It is within the Company's discretion to make these additional amounts available to the SSLP.

        As of December 31, 2011 and December 31, 2010, the SSLP had total assets of $5.0 billion and $2.6 billion, respectively. GE's investment in the SSLP consisted of senior notes of $3.8 billion and $1.9 billion and subordinated certificates of $149 million and $78 million at December 31, 2011 and 2010, respectively. The subordinated certificates are junior to the senior notes invested by GE and the Company owned 87.5% and 88.6% of the outstanding subordinated certificates as of December 31, 2011 and 2010, respectively. The SSLP's portfolio consisted of senior and unitranche loans to 32 and 20 different issuers as of December 31, 2011 and 2010, respectively. At December 31, 2011 and 2010, the portfolio was comprised of all first lien senior secured loans to U.S. middle-market companies and none of these loans were on non-accrual status. At December 31, 2011 and 2010, the largest loan to a single issuer in the SSLP's portfolio in aggregate principal amount was $300.0 million and $270.0 million, respectively, and loans to the top five issuers totaled $1.4 billion and $1.1 billion, respectively. The portfolio companies in the SSLP are in industries similar to the companies in Ares Capital's portfolio.

        The amortized cost and fair value of the SSLP Certificates held by the Company was $1,034,254 and $1,059,178, respectively, at December 31, 2011, and $537,439 and $561,674, respectively, at December 31, 2010. The SSLP Certificates pay a weighted average coupon of approximately LIBOR plus 8.0% and also entitle the Company to receive a portion of the excess cash flow from the loan portfolio, which may result in a return greater than the contractual coupon. The Company's yield on its investment in the SSLP at fair value was 15.7% and 15.8% at December 31, 2011 and 2010, respectively. For the years ended December 31, 2011 and December 31, 2010, the Company earned interest income of $118,420 and $50,013, respectively, in respect of its SSLP investment. The Company is also entitled to certain other sourcing and management fees in connection with the SSLP.

5.     BORROWINGS

        In accordance with the Investment Company Act, with certain limited exceptions, the Company is only allowed to borrow amounts such that its asset coverage, as defined in the Investment Company Act, is at least 200% after such borrowing. As of December 31, 2011 our asset coverage for borrowed amounts was 252%.

F-60

---

        The Company's outstanding debt as of December 31, 2011 and 2010 was as follows:

        The weighted average stated interest rate and weighted average maturity, both on aggregate principal amount, of all our principal debt outstanding as of December 31, 2011 were 4.8% and 9.3 years, respectively, and as of December 31, 2010 were 5.2% and 11.8 years, respectively.

Revolving Funding Facility

        In October 2004, we formed Ares Capital CP Funding LLC ("Ares Capital CP"), a wholly owned subsidiary of the Company, through which we established a revolving facility (as amended, the "Revolving Funding Facility") that, as amended at such time, allowed Ares Capital CP to issue up to $350,000 of variable funding certificates ("VFC"). On May 7, 2009, the Company and Ares Capital CP entered into an amendment that, among other things, converted the Revolving Funding Facility from a revolving facility to an amortizing facility, extended the maturity from July 21, 2009 to May 7, 2012, reduced the availability from $350,000 to $225,000 (with a reduction in the outstanding balance required by each of December 31, 2010 and December 31, 2011) and decreased the advance rates applicable to certain types of eligible loans. In addition, the interest rate charged on the Revolving Funding Facility was increased from the commercial paper rate plus 2.50% to the commercial paper, Eurodollar or adjusted Eurodollar rate, as applicable, plus 3.50% and the commitment fee requirement was removed.

F-61

---

        On July 21, 2009, the Company and Ares Capital CP entered into an agreement to establish an additional revolving facility (the "Revolving Funding II Facility") for an aggregate principal amount not exceeding $200,000 at any one time outstanding. The Revolving Funding II Facility was scheduled to expire on July 21, 2012.

        On January 22, 2010, the Company and Ares Capital CP combined the Revolving Funding II Facility into the Revolving Funding Facility, creating a single $400,000 revolving securitized facility. In connection with the combination, we terminated the Revolving Funding II Facility and entered into an Amended and Restated Purchase and Sale Agreement with Ares Capital CP Funding Holdings LLC, our wholly owned subsidiary ("CP Holdings"), pursuant to which we may sell to CP Holdings certain loans that we have originated or acquired from time to time, which CP Holdings will subsequently sell to Ares Capital CP, which is a wholly owned subsidiary of CP Holdings. The Revolving Funding Facility is secured by all of the assets held by, and the membership interest in, Ares Capital CP. The January 22, 2010 amendment to the Revolving Funding Facility, among other things, extended the maturity date of the facility to January 22, 2013. On January 18, 2011, we and Ares Capital CP amended the Revolving Funding Facility to, among other things, provide for a three year reinvestment period until January 18, 2014 (with two one-year extension options, subject to our and our lenders' consent, see Note 19 for subsequent events relating to the Revolving Funding Facility) and extend the stated maturity date to January 18, 2016 (with two one-year extension options, subject to our and our lenders' consent, see Note 19 for subsequent events relating to the Revolving Funding Facility). On October 13, 2011, the Revolving Funding Facility was amended to increase the facility size to $500,000.

        As part of the Revolving Funding Facility, we and Ares Capital CP are subject to limitations as to how borrowed funds may be used including restrictions on geographic concentrations, sector concentrations, loan size, payment frequency and status, average life, collateral interests and investment ratings as well as regulatory restrictions on leverage which may affect the amount of VFC that we may issue from time to time. There are also certain requirements relating to portfolio performance, including required minimum portfolio yield and limitations on delinquencies and charge offs, violation of which could result in the early amortization of the Revolving Funding Facility and limit further advances under the Revolving Funding Facility and in some cases could be an event of default. The Revolving Funding Facility is also subject to a borrowing base that applies different advance rates to assets held by Ares Capital CP. Such limitations, requirements, and associated defined terms are as provided for in the documents governing the Revolving Funding Facility. As of December 31, 2011, the Company and Ares Capital CP were in material compliance with the terms of the Revolving Funding Facility.

        As of December 31, 2011 and 2010, there was $463,000 and $242,050 outstanding under the Revolving Funding Facility, respectively.

        Prior to the January 22, 2010 amendment, the interest rate charged on the Revolving Funding Facility was based on the commercial paper rate plus 3.50%. After January 22, 2010, subject to certain exceptions, the interest rate charged on the Revolving Funding Facility is based on LIBOR plus an applicable spread of between 2.25% and 3.75% or on a "base rate" (which is the higher of a prime rate, or the federal funds rate plus 0.50%) plus an applicable spread of between 1.25% to 2.75%, in each case, based on a pricing grid depending upon our credit rating (see Note 19 for subsequent events relating to the Revolving Funding Facility). As of December 31, 2011 and for the period from January 22, 2010 through December 31, 2011, the effective LIBOR spread under the Revolving Funding Facility was 2.75%. As of December 31, 2011 and December 31, 2010, the rate in effect was one month LIBOR, which was 0.30% and 0.26%, respectively.

        We are also required to pay a commitment fee of between 0.50% and 2.00% depending on the usage level on any unused portion of the Revolving Funding Facility. Prior to May 7, 2009, we were required to pay a commitment fee for any unused portion of the Revolving Funding Facility equal to

F-62

---

0.50% per annum for any unused portion of the Revolving Funding Facility. Prior to January 22, 2010, we were also required to pay a commitment fee on any unused portion of the Revolving Funding II Facility of between 0.50% and 2.00% depending on the usage level.

        The components of interest and credit facility fees expense, cash paid for interest expense, average interest rates (i.e., rate in effect plus the spread) and average outstanding balances for the Revolving Funding Facility were as follows:

Revolving Credit Facility

        In December 2005, we entered into a senior secured revolving credit facility (as amended and restated, the "Revolving Credit Facility"), under which, as amended, the lenders agreed to extend credit to the Company. On January 22, 2010, we entered into an agreement to amend and restate the Revolving Credit Facility. The amendment and restatement of the Revolving Credit Facility, among other things, increased the size of the facility from $525,000 to $690,000 (comprised of $615,000 in commitments on a stand-alone basis and an additional $75,000 in commitments contingent upon the closing of the Allied Acquisition), extended the maturity date from December 28, 2010 to January 22, 2013 and modified pricing. The Revolving Credit Facility also includes an "accordion" feature that allows, under certain circumstances, for an increase in the size of the facility to a maximum of $1,050,000. During the year ended December 31, 2010, we exercised this "accordion" feature and increased the size of the facility by $120,000 to bring the total facility size to $810,000. The Revolving Credit Facility generally requires payments of interest at the end of each LIBOR interest period, but no less frequently than quarterly, on LIBOR-based loans, and monthly payments of interest on other loans. All principal is due upon maturity.

        Under the Revolving Credit Facility, we are required to comply with various covenants, reporting requirements and other customary requirements for similar revolving credit facilities, including, without limitation, covenants related to: (a) limitations on the incurrence of additional indebtedness and liens, (b) limitations on certain investments, (c) limitations on certain restricted payments, (d) maintaining a certain minimum stockholders' equity, (e) maintaining a ratio of total assets (less total liabilities) to total indebtedness, of the Company and its subsidiaries, of not less than 2.0:1.0, (f) maintaining minimum liquidity, and (g) limitations on the creation or existence of agreements that prohibit liens on certain properties of the Company and its subsidiaries. As of December 31, 2011, the Company was in material compliance with terms of the Revolving Credit Facility.

        In addition to the asset coverage ratio described above, borrowings under the Revolving Credit Facility (and the incurrence of certain other permitted debt) will be subject to compliance with a borrowing base that will apply different advance rates to different types of assets in our portfolio.

F-63

---

        As of December 31, 2011 and 2010, there was $395,000 and $146,000, respectively, outstanding under the Revolving Credit Facility. The Revolving Credit Facility also provides for a sub-limit for the issuance of letters of credit for up to an aggregate amount of $100,000. As of December 31, 2011 and 2010, the Company had $47,249 and $7,281 in standby letters of credit issued through the Revolving Credit Facility, respectively. The amount available for borrowing under the Revolving Credit Facility is reduced by any standby letters of credit issued. At December 31, 2011, there was $404,751 available for borrowing (net of standby letters of credit issued) under the Revolving Credit Facility.

        Prior to amending and restating the Revolving Credit Facility on January 22, 2010, subject to certain exceptions, the interest rate charged on the Revolving Credit Facility was based on LIBOR plus 1.00% or on an "alternate base rate" (which was the highest of a prime rate, the federal funds rate plus 0.50%, or one month LIBOR plus 1.00%). After January 22, 2010, subject to certain exceptions, the interest rate charged on the Revolving Credit Facility is based on LIBOR plus an applicable spread of between 2.50% and 4.00% or on the "alternate base rate" plus an applicable spread of between 1.50% and 3.00%, in each case, based on a pricing grid depending upon our credit rating. As of December 31, 2011 and for the period from January 22, 2010 through December 31, 2011, the effective LIBOR spread under the Revolving Credit Facility was 3.00%. As of December 31, 2011, the one, two, three and six month LIBOR was 0.30%, 0.43%, 0.58% and 0.81%, respectively. As of December 31, 2010, the one, two, three and six month LIBOR was 0.26%, 0.28%, 0.30% and 0.46%, respectively.

        In addition to the stated interest expense on the Revolving Credit Facility, the Company is required to pay a commitment fee of 0.50% per annum on any unused portion of the Revolving Credit Facility and a letter of credit fee of 3.25% per annum on letters of credit issued, both of which are payable quarterly. The letter of credit fee is also based on a pricing grid depending on our credit ratings. In connection with the expansion and extension of the Revolving Credit Facility in January 2010, we paid arrangement fees totaling approximately $15,600.

        With certain exceptions, the Revolving Credit Facility is secured by substantially all of the assets in our portfolio (other than investments held by Ares Capital CP under the Revolving Funding Facility, those held as a part of the Debt Securitization, discussed below, and certain other investments).

        The components of interest and credit facility fees expense, cash paid for interest expense, average interest rates (i.e., rate in effect plus the spread) and average outstanding balances for the Revolving Credit Facility were as follows:

Debt Securitization

        In July 2006, through ARCC Commercial Loan Trust 2006, a vehicle serviced by our wholly owned subsidiary, ARCC CLO 2006 LLC ("ARCC CLO"), the Company completed a $400,000 debt securitization (the "Debt Securitization") and issued approximately $314,000 aggregate principal amount of asset-backed notes (the "CLO Notes") to third parties that are secured by a pool of middle-market loans that were purchased or originated by the Company. The Company initially retained approximately $86,000 of aggregate principal amount of certain "BBB" and non-rated securities in the Debt Securitization. The CLO Notes are included in the consolidated balance sheet.

        During the year ended December 31, 2011, we had net repayments of $28,265, $9,587, $20,819 and $19,095 of the Class A-1-A, Class A-1A-VFN, Class A-2A Notes and Class A-2B Notes, respectively. During the year ended December 31, 2010, we repaid $39,996, $26,665 and $51,795 of the Class A-1-A, Class A-1A-VFN and Class A-2A Notes, respectively. During the year ended December 31, 2009, we repurchased, in several open market transactions, $34,790 of CLO Notes consisting of $14,000 of Class B Notes and $20,790 of Class C Notes for a total purchase price of $8,247. As a result of these purchases, we recognized a $26,543 gain on the extinguishment of debt during the year ended December 31, 2009. As of December 31, 2011, we held an aggregate principal amount of $120,790 of CLO Notes (the "Retained Notes") in total. The CLO Notes mature on December 20, 2019, and, as of December 31, 2011, there was $77,531 outstanding under the Debt Securitization (excluding the Retained Notes).

        During the first five years from the closing date, principal collections received on the underlying collateral could be used to purchase new collateral. This reinvestment period expired on June 17, 2011. Because the reinvestment period expired, all principal collections received on the underlying collateral will be used to paydown the CLO Notes outstanding in their order of legal priority.

        All of the notes are secured by the assets of ARCC Commercial Loan Trust 2006, including commercial loans totaling $308,100 as of the closing date, which were sold to the trust by the Company, the originator and servicer of the assets. Additional commercial loans were purchased by the trust from the Company primarily using the proceeds from the Class A-1A VFN Notes as well as proceeds from loan repayments. As of December 31, 2011, the Company was in material compliance with the terms of the Debt Securitization.

        The classes, amounts and interest rates (expressed as a spread to LIBOR) of the CLO Notes as of December 31, 2011 and 2010 are as follows:

        The interest charged under the Debt Securitization is based on 3-month LIBOR, which as of December 31, 2011 was 0.56% and as of December 31, 2010 was 0.30%. The blended interest rate charged on the CLO Notes, excluding fees, at December 31, 2011 and 2010, was approximately 3-month LIBOR plus 45 and 36 basis points, respectively.

        The Company was also required to pay a commitment fee of 0.175% for any unused portion of the Class A-1A VFN Notes through June 17, 2011, which is included in facility fees below.

        The components of interest and credit facility fees expense, cash paid for interest expense, average interest rates (i.e., rate in effect plus the spread) and average outstanding balances for the Debt Securitization are as follows:

Unsecured Notes

Allied Unsecured Notes

        As part of the Allied Acquisition, the Company assumed all outstanding debt obligations of Allied Capital, including Allied Capital's unsecured notes, which consisted of 6.625% Notes due on July 15, 2011 (the "2011 Notes"), 6.000% Notes due on April 1, 2012 (the "2012 Notes") and 6.875% Notes due on April 15, 2047 (the "2047 Notes" and, together with the 2011 Notes and the 2012 Notes, the "Allied Unsecured Notes"). On March 16, 2011 we redeemed the remaining balance of the 2011 Notes for a total redemption price (including a redemption premium) of $306,800, in accordance with the terms of the indenture governing the 2011 Notes, which resulted in a loss on the extinguishment of debt of $8,860. On April 27, 2011, we redeemed the remaining balance of the 2012 Notes for a total redemption price (including a redemption premium) of $169,338, in accordance with the terms of the indenture governing the 2012 Notes, which resulted in a loss on the extinguishment of debt of $10,458.

        As of December 31, 2011 and 2010, the Company had the following outstanding Allied Unsecured Notes:

        The 2047 Notes bear interest at a rate of 6.875% and mature on April 15, 2047. The 2047 Notes require payment of interest quarterly, and all principal is due upon maturity. The 2047 Notes may be redeemed in whole or in part at any time or from time to time at our option on or after April 15, 2012, at a par redemption price of $25 per security plus accrued and unpaid interest and upon the occurrence of certain tax events as stipulated in the indenture governing the 2047 Notes.

        In accordance with ASC 805-10, the initial carrying value of the Allied Unsecured Notes was equal to the fair value as of April 1, 2010 resulting in an initial unaccreted discount from the principal value of the Allied Unsecured Notes of approximately $65,800. Accretion expense related to this discount which is included in "interest and credit facility fees" in the accompanying statement of operations.

        The Company may purchase the 2047 Notes in the market to the extent permitted by the Investment Company Act. During the year ended December 31, 2010, the Company purchased $19,350 principal amount of the 2011 Notes and $34,400 principal amount of the 2012 Notes. As a result of these transactions, the Company recognized a realized loss of $1,961 during the year ended December 31, 2010.

        The components of interest expense and cash paid for interest expense for the Allied Unsecured Notes are as follows:

2040 Notes

        On October 21, 2010, we issued $200,000 aggregate principal amount of senior unsecured notes that mature on October 15, 2040 (the "2040 Notes"). The 2040 Notes may be redeemed in whole or in part at any time or from time to time at our option on or after October 15, 2015, at a par redemption price of $25 per security plus accrued and unpaid interest. The 2040 Notes bear interest at a rate of 7.75% per annum, payable quarterly, and all principal is due upon maturity. Total proceeds from the issuance of the 2040 Notes, net of underwriting discounts and offering costs, were approximately $193,000.

        The components of interest expense and cash paid for interest expense for the 2040 Notes are as follows:

        The 2047 Notes and the 2040 Notes contain certain covenants, including covenants requiring Ares Capital to comply with Section 18(a)(1)(A) as modified by Section 61(a)(1) of the Investment Company Act and to provide financial information to the holders of such notes under certain circumstances. These covenants are subject to important limitations and exceptions. As of December 31, 2011, the Company was in material compliance with the terms of the 2047 Notes and the 2040 Notes.

Convertible Notes

        In January 2011, we issued $575,000 aggregate principal amount of unsecured convertible senior notes that mature on February 1, 2016 (the "February 2016 Convertible Notes"), unless previously

F-67

---

converted or repurchased in accordance with their terms. In March 2011, we issued $230,000 aggregate principal amount of unsecured convertible senior notes that mature on June 1, 2016 (the "June 2016 Convertible Notes" and, together with the February 2016 Convertible Notes, the "Convertible Notes"), unless previously converted or repurchased in accordance with their terms. We do not have the right to redeem the Convertible Notes prior to maturity. The February 2016 Convertible Notes and the June 2016 Convertible Notes bear interest at a rate of 5.75% and 5.125%, respectively, per year, payable semi-annually.

        In certain circumstances, the February 2016 Convertible Notes will be convertible into cash, shares of Ares Capital's common stock or a combination of cash and shares of our common stock, at our election, at an initial conversion rate of 52.2766 shares of common stock per one thousand dollar principal amount of the February 2016 Convertible Notes, which is equivalent to an initial conversion price of approximately $19.13 per share of our common stock, subject to customary anti-dilution adjustments. The initial conversion price of the February 2016 Convertible Notes was approximately 17.5% above the $16.28 per share closing price of our common stock on January 19, 2011. In certain circumstances, the June 2016 Convertible Notes will be convertible into cash, shares of Ares Capital's common stock or a combination of cash and shares of our common stock, at our election, at an initial conversion rate of 52.5348 shares of common stock per one thousand dollar principal amount of the June 2016 Convertible Notes, which is equivalent to an initial conversion price of approximately $19.04 per share of our common stock, subject to customary anti-dilution adjustments. The initial conversion price of the June 2016 Convertible Notes was approximately 17.5% above the $16.20 per share closing price of our common stock on March 22, 2011. At December 31, 2011, the principal amounts of both the February 2016 Convertible Notes and the June 2016 Convertible Notes exceeded the value of the underlying shares multiplied times the per share closing price of our common stock.

        The Convertible Notes are Ares Capital's senior unsecured obligations and rank senior in right of payment to our existing and future indebtedness that is expressly subordinated in right of payment to the Convertible Notes; equal in right of payment to our existing and future unsecured indebtedness that is not expressly subordinated; effectively junior in right of payment to any of our secured indebtedness (including existing unsecured indebtedness that we later secure) to the extent of the value of the assets securing such indebtedness; and structurally junior to all existing and future indebtedness (including trade payables) incurred by our subsidiaries, financing vehicles or similar facilities.

        Prior to the close of business on the business day immediately preceding August 15, 2015, holders may convert their February 2016 Convertible Notes only under certain circumstances set forth in the indenture governing the terms of the February 2016 Convertible Notes (the "February 2016 Indenture"). On or after August 15, 2015 until the close of business on the scheduled trading day immediately preceding February 1, 2016, holders may convert their February 2016 Convertible Notes at any time. Upon conversion, we will pay or deliver, as the case may be, at our election, cash, shares of our common stock or a combination of cash and shares of our common stock, subject to the requirements of the February 2016 Indenture. Prior to the close of business on the business day immediately preceding December 15, 2015, holders may convert their June 2016 Convertible Notes only under certain circumstances set forth in the indenture governing the terms of the June 2016 Convertible Notes (the "June 2016 Indenture"). On or after December 15, 2015 until the close of business on the scheduled trading day immediately preceding June 1, 2016, holders may convert their June 2016 Convertible Notes at any time. Upon conversion, we will pay or deliver, as the case may be, at our election, cash, shares of our common stock or a combination of cash and shares of our common stock, subject to the requirements of the June 2016 Indenture.

        In addition, if we engage in certain corporate events as described in both the February 2016 Indenture and the June 2016 Indenture (collectively, the "Convertible Notes Indentures"), holders of the Convertible Notes may require us to repurchase for cash all or part of the Convertible Notes at a

F-68

---

repurchase price equal to 100% of the principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid interest through, but excluding, the required repurchase date.

        The Convertible Notes Indentures contain certain covenants, including covenants requiring us to comply with Section 18(a)(1)(A) as modified by Section 61(a)(1) of the Investment Company Act and to provide financial information to the holders of the Convertible Notes under certain circumstances. These covenants are subject to important limitations and exceptions that are described in the Convertible Notes Indentures. As December 31, 2011, the Company was in material compliance with the terms of the Convertible Notes Indentures.

        The Convertible Notes are accounted for in accordance with ASC 470-20 (previously FASB Staff Position No. APB 14-1, "Accounting for Convertible Debt Instruments That May Be Settled in Cash upon Conversion (Including Partial Cash Settlement)"). Upon conversion of any of the Convertible Notes, we intend to pay the outstanding principal amount in cash and to the extent that the conversion value exceeds the principal amount, we have the option to pay in cash or shares of our common stock (or a combination of cash and shares) in respect of the excess amount, subject to the requirements of the Convertible Notes Indentures. The Company has determined that the embedded conversion options in both the February 2016 Convertible Notes and the June 2016 Convertible Notes are not required to be separately accounted for as a derivative under GAAP. In accounting for the February 2016 Convertible Notes, we estimated at the time of issuance that the values of the debt and equity components of the February 2016 Convertible Notes were approximately 93% and 7%, respectively. In accounting for the June 2016 Convertible Notes, we estimated at the time of issuance that the values of the debt and equity components of the June 2016 Convertible Notes were approximately 93% and 7%, respectively. The original issue discount equal to the equity component of 7% of both the June 2016 Convertible Notes and the February 2016 Convertible Notes was recorded in "capital in excess of par value" in the accompanying consolidated balance sheet. As a result, we record interest expense comprised of both stated interest expense as well as accretion of the original issue discount. Additionally, the issuance costs associated with the Convertible Notes were allocated to the debt and equity components in proportion to the allocation of the proceeds and accounted for as debt issuance costs and equity issuance costs, respectively.

        At the time of issuance, the debt issuance costs and equity issuance costs for the February 2016 Convertible Notes were $15,778 and $1,188, respectively, and for the June 2016 Convertible Notes were $5,913 and $445, respectively. At the time of issuance and as of December 31, 2011, the equity component, net of issuance costs as recorded in the "capital in excess of par value" in the consolidated balance sheet for the February 2016 Convertible Notes and the June 2016 Convertible Notes was $39,063 and $15,653, respectively.

        As of December 31, 2011 the components of the carrying value of the Convertible Notes were as follows:

F-69

---

        For the year ended December 31, 2011 the components of interest expense and cash paid for interest expense for the February 2016 Convertible Notes were as follows:

        The estimated effective interest rate of the debt component of the February 2016 Convertible Notes, equal to the stated interest of 5.75% plus the accretion of the original issue discount, was approximately 7.49% for the year ended December 31, 2011.

        For the year ended December 31, 2011, the components of interest expense and cash paid for interest expense for the June 2016 Convertible Notes were as follows:

        The estimated effective interest rate of the debt component of the June 2016 Convertible Notes equal to the stated interest of 5.125% plus the accretion of the original issue discount, was approximately 6.79% for the year ended December 31, 2011.

6.     DERIVATIVE INSTRUMENTS

        In October 2008, we entered into an interest rate swap agreement that terminated on December 20, 2010 to mitigate our exposure to adverse fluctuations in interest rates for a total notional amount of $75,000. Under the interest rate swap agreement, we paid a fixed interest rate of 2.985% and receive a floating rate based on the prevailing three-month LIBOR. For the years ended December 31, 2010 and 2009, we recognized $1,741 and $423, in unrealized appreciation related to this swap agreement. Upon termination of this swap agreement in 2010, no realized gain or loss was recognized.

7.     COMMITMENTS AND CONTINGENCIES

Portfolio Company Commitments

        The Company has various commitments to fund investments in its portfolio as described below.

F-70

---

        As of the years ended December 31, 2011 and 2010, the Company had the following commitments to fund various revolving and delayed draw senior secured and subordinated loans, including commitments the funding of which is at (or substantially at) the Company's discretion:

        Included within the total revolving and delayed draw commitments as of December 31, 2011 are commitments to issue up to $79,372 in standby letters of credit through a financial intermediary on behalf of certain portfolio companies. Under these arrangements, if the standby letters of credit were to be issued, the Company would be required to make payments to third parties if the portfolio companies were to default on their related payment obligations. As of December 31, 2011, the Company had $43,321 in standby letters of credit issued and outstanding under these commitments on behalf of the portfolio companies, of which no amounts were recorded as a liability on our balance sheet as such letters of credit are considered in the valuation of the investments in the portfolio company. Of these letters of credit $41,171 expire in 2012 and $2,150 expire in 2013.

        As of the years ended December 31, 2011 and 2010, the Company was party to subscription agreements to fund equity investments in private equity investment partnerships:

        In the ordinary course of business, Allied Capital had issued guarantees on behalf of certain portfolio companies. Under these arrangements, payments would be required to be made to third parties if the portfolio companies were to default on their related payment. As part of the Allied Acquisition, the Company assumed such outstanding guarantees or similar obligations. As a result, as of December 31, 2011 and 2010, the Company had outstanding guarantees or similar obligations totaling $800.

        Further in the ordinary course of business, we may sell certain of our investments to third party purchasers. In particular, since the Allied Acquisition we have sold and currently continue to seek opportunities to sell, certain of Allied Capital's equity investments larger than those we have historically made and controlled portfolio company equity investments. In connection with these sales (as well as certain other sales) we have, and may continue to do so in the future, agreed to indemnify such

F-71

---

purchasers for future liabilities arising from the investments and the related sale transaction. Such indemnification provisions may give rise to future liabilities.

        As of December 31, 2011, one of the Company's portfolio companies, Ciena Capital LLC ("Ciena"), had one non-recourse securitization Small Business Administration ("SBA") loan warehouse facility, which has reached its maturity date but remains outstanding. Ciena is working with the providers of the SBA loan warehouse facility with regard to the repayment of that facility. Allied Capital had previously issued a performance guaranty (which Ares Capital succeeded to as a result of the Allied Acquisition) whereby Ares Capital must indemnify the warehouse providers for any damages, losses, liabilities and related costs and expenses that they may incur as a result of Ciena's failure to perform any of its obligations as loan originator, loan seller or loan servicer under the warehouse facility. As of December 31, 2011, there are no known issues or claims with respect to this performance guaranty.

Lease Commitments

        The Company is obligated under a number of operating leases for office spaces with terms ranging from less than one year to more than 15 years. Rent expense for the years ended December 31, 2011, 2010 and 2009 was $3,343, $5,167 and $1,803, respectively.

        The following table shows future minimum payments under the Company's operating leases:

        For certain of its operating leases, the Company has entered into subleases including ones with Ares Management and Ivy Hill Asset Management, L.P. ("IHAM") (see Note 13).

        The following table shows future expected rental payments to be received under the Company's subleases:

8.     FAIR VALUE OF FINANCIAL INSTRUMENTS

        Effective January 1, 2008, the Company adopted ASC 825-10 (previously SFAS No. 159, the Fair Value Option for Financial Assets and Liabilities), which provides companies the option to report selected financial assets and liabilities at fair value. ASC 825-10 also establishes presentation and disclosure requirements designed to facilitate comparisons between companies that choose different

F-72

---

measurement attributes for similar types of assets and liabilities and to more easily understand the effect of the company's choice to use fair value on its earnings. ASC 825-10 also requires entities to display the fair value of the selected assets and liabilities on the face of the balance sheet. The Company has not elected the ASC 8 25-10 option to report selected financial assets and liabilities at fair value. With the exception of the line items entitled "other assets" and "debt," which are reported at amortized cost, all assets and liabilities approximate fair value on the balance sheet. The carrying value of the line items entitled "interest receivable," "receivable for open trades," "payable for open trades," "accounts payable and accrued expenses," "management and incentive fees payable" and "interest and facility fees payable" approximate fair value due to their short maturity.

        Effective January 1, 2008, the Company adopted ASC 820-10 (previously SFAS No. 157, Fair Value Measurements), which expands the application of fair value accounting. ASC 820-10 defines fair value, establishes a framework for measuring fair value in accordance with GAAP and expands disclosure of fair value measurements. ASC 820-10 determines fair value to be the price that would be received for an investment in a current sale, which assumes an orderly transaction between market participants on the measurement date. ASC 820-10 requires the Company to assume that the portfolio investment is sold in its principal market to market participants or, in the absence of a principal market, the most advantageous market, which may be a hypothetical market. Market participants are defined as buyers and sellers in the principal or most advantageous market that are independent, knowledgeable, and willing and able to transact. In accordance with ASC 820-10, the Company has considered its principal market as the market in which the Company exits its portfolio investments with the greatest volume and level of activity. ASC 820-10 specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. In accordance with ASC 820-10, these inputs are summarized in the three broad levels listed below:

•

Level 1—Valuations based on quoted prices in active markets for identical assets or liabilities that the Company has the ability to access.



•

Level 2—Valuations based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly.



•

Level 3—Valuations based on inputs that are unobservable and significant to the overall fair value measurement.

        Transfers between levels, if any, are recognized at the beginning of the quarter in which the transfers occur. In addition to using the above inputs in investment valuations, we continue to employ the net asset valuation policy approved by our board of directors that is consistent with ASC 820-10 (see Note 2). Consistent with our valuation policy, we evaluate the source of inputs, including any markets in which our investments are trading (or any markets in which securities with similar attributes are trading), in determining fair value. Our valuation policy considers the fact that because there is not a readily available market value for most of the investments in our portfolio, the fair value of the investments must typically be determined using unobservable inputs.

        Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the fair value of our investments may fluctuate from period to period. Additionally, the fair value of our investments may differ significantly from the values that would have been used had a ready market existed for such investments and may differ materially from the values that we may ultimately realize. Further, such investments are generally subject to legal and other restrictions on resale or otherwise are less liquid than publicly traded securities. If we were required to liquidate a portfolio investment in a forced or liquidation sale, we could realize significantly less than the value at which we have recorded it.

F-73

---

        In addition, changes in the market environment and other events that may occur over the life of the investments may cause the gains or losses ultimately realized on these investments to be different than the gains or losses reflected in the valuations currently assigned.

        The following table presents fair value measurements of cash and cash equivalents and investments as of December 31, 2011:

        The following tables present changes in investments that use Level 3 inputs for the years ended December 31, 2011:

        As of December 31, 2011, the net unrealized depreciation on the investments that use Level 3 inputs was $14,157.

        The following table presents fair value measurements of cash and cash equivalents and investments as of December 31, 2010:

F-74

---

        The following tables present changes in investments that use Level 3 inputs for the year ended December 31, 2010:

        As of December 31, 2010, the net unrealized appreciation on the investments that use Level 3 inputs was $29,735. Transfers between levels, if any, are recognized at the beginning of the quarter in which transfers occur.

        Following are the carrying and fair values of our debt instruments as of December 31, 2011 and December 31, 2010. Fair value is estimated by discounting remaining payments using applicable current market rates which take into account changes in the Company's marketplace, credit ratings, or market quotes, if available.

9.     STOCKHOLDERS' EQUITY

        There were no sales of our equity securities during the year ended December 31, 2011.

        The following table summarizes the total shares issued and proceeds received in public offerings of the Company's common stock net of underwriting discounts and offering costs for the years ended December 31, 2010 and 2009:

        For the years ended December 31, 2010 and 2009, the Company incurred approximately $1,440 and $806 in offering costs, respectively.

        In connection with the Allied Acquisition, on April 1, 2010, the Company issued 58,493 shares valued at approximately $872,727.

        In November 2010, the Company completed a public add-on equity offering (the "November Add-on Offering") of 11,500 shares of common stock (including 1,500 shares purchased pursuant to the underwriters' over-allotment option) at a price of $16.50 per share, less an underwriting discount totaling approximately $0.7425 per share. Total proceeds received from the November Add-on Offering, net of underwriting discounts and offering costs, were approximately $180,642.

        In February 2010, the Company completed a public add-on equity offering (the "February Add-on Offering") of approximately 22,958 shares of common stock (including approximately 1,958 shares purchased pursuant to the partial exercise by the underwriters of their over-allotment option) at a price of $12.75 per share, less an underwriting discount totaling approximately $0.6375 per share. Total proceeds received from the February Add-on Offering, net of underwriting discounts and offering costs, were approximately $277,207.

        In August 2009, the Company completed a public add-on equity offering (the "August Add-on Offering") of approximately 12,440 shares of common stock (including approximately 1,440 shares purchased pursuant to the underwriters' over-allotment option) at a price of $9.25 per share, less an underwriting discount totaling approximately $0.42 per share. The shares were offered at a discount from the then most recently determined net asset value per share of $11.21 pursuant to authority granted by our common stockholders at the annual meeting of stockholders held on May 4, 2009. Total proceeds received from the August Add-on Offering, net of underwriting discounts and offering costs, were approximately $109,086.

10.   EARNINGS PER SHARE

        The following information sets forth the computations of basic and diluted net increase in stockholders' equity resulting from operations per share for the years ended December 31, 2011, 2010 and 2009:

        For the purposes of calculating diluted earnings per share, since the average closing price of the Company's common stock for the period from the time of issuance of both the February 2016 Convertible Notes and the June 2016 Convertible Notes through December 31, 2011 was less than the current conversion price for each respective series of the Convertible Notes, the underlying shares for the intrinsic value of the embedded options had no impact.

11.   INCOME AND EXCISE TAXES

        For income tax purposes, dividends and distributions paid to stockholders are reported as ordinary income, capital gains, non-taxable return of capital, or a combination thereof. Dividends or distributions paid per common share for the years ended December 31, 2011, 2010 and 2009 were taxable as follows (unaudited):

F-77

---

        The following reconciles net increase in stockholders' equity resulting from operations to taxable income for the years ended December 31, 2011, 2010 and 2009:

        Taxable income generally differs from net increase in stockholders' equity resulting from operations for financial reporting purposes due to temporary and permanent differences in the recognition of income and expenses, and generally excludes net unrealized gains or losses, as unrealized gains or losses are generally not included in taxable income until they are realized. Additionally, on April 1, 2010, the Company acquired Allied Capital in a tax free merger and recorded a book gain of $195,876, which is not a realized event for tax purposes. Similarly, there were certain merger-related items that vary in their deductibility for GAAP and tax.

        Capital losses in excess of capital gains earned in a tax year may generally be carried forward and used to offset capital gains, subject to certain limitations. As of December 31, 2011, the Company estimates that it will have a capital loss carryforward of approximately $207 million available for use in later tax years. Because of the loss limitation rules of the Code, some of the tax basis losses may be limited in their use. The unused balance will be carried forward and utilized as gains are realized, subject to such limitations. In addition to the capital loss carryforwards, the Company realized net losses totaling approximately $0.3 billion from the Allied Capital portfolio since the acquisition through December 31, 2011, however, these losses have not yet been deducted for tax purposes as their deductibility in 2011 and 2010 was limited by the Code. While our ability to utilize losses in the future depends upon a variety of factors that cannot be known in advance, substantially all of our capital loss carryforwards and the net realized losses from the Allied Capital portfolio may become permanently unavailable due to limitations by the Code.

        For 2010, the Company had taxable income in excess of distributions made from such taxable income of approximately $64 million and therefore, the Company carried forward the excess for distribution to shareholders in 2011. For 2011, the Company had taxable income in excess of the distributions made from such taxable income during the year, and therefore, the Company has elected to carry forward the excess for distribution to shareholders in 2012. The amount carried forward to 2012 is estimated to be approximately $170 million, although this amount will not be finalized until the 2011 tax returns are filed in 2012. To the extent that the Company determines that its estimated current

F-78

---

year annual taxable income will be in excess of estimated current year dividend distribution from such income, the Company accrues excise tax on estimated excess taxable income. For the years ended December 31, 2011 and 2010, a net expense of $6,605 and $2,229 was recorded for U.S. federal excise tax, respectively. For the year ended December 31, 2009, a net benefit of $30 was recorded for U.S. federal excise tax.

        As of December 31, 2011, the cost basis of investments for tax purposes was $6.1 billion resulting in estimated gross unrealized gains and losses of $0.2 billion and $1.2 billion, respectively. As of December 31, 2010, the cost basis of investments for tax purposes was $5.4 billion resulting in estimated gross unrealized gains and losses of $0.3 billion and $1.4 billion, respectively. As of December 31, 2011 and 2010, the cost of investments for tax purposes was greater than the amortized cost of investments for book purposes of $5.1 billion and $4.3 billion, respectively, primarily as a result of the Allied Acquisition. The Allied Acquisition qualified as a tax free merger, which resulted in the acquired assets retaining Allied Capital's cost basis at the merger date.

        In general, the Company may make certain adjustments to the classification of stockholders' equity as a result of permanent book-to-tax differences, which may include merger-related items, differences in the book and tax basis of certain assets and liabilities, and nondeductible federal taxes, among other items. During the year ended December 31, 2011, the Company increased accumulated undistributed net investment income by $7,474, increased accumulated net realized loss on sale of investments by $126,234 and increased capital in excess of par value by $118,760.

14.   IVY HILL ASSET MANAGEMENT, L.P. AND OTHER MANAGED FUNDS

        In November 2007, the Company established IHAM to serve as a manager for Ivy Hill Middle Market Credit Fund, Ltd. ("Ivy Hill I"), an unconsolidated investment vehicle focusing on investments in middle-market loans. From inception until the second quarter of 2009, IHAM's financial results were consolidated with those of the Company. In June 2009, because of a shift in activity from being primarily a manager, with no dedicated employees, of funds in which the Company had invested debt and equity, to a manager with individuals dedicated to managing an increasing number of third party funds, the Company concluded that GAAP required the financial results of IHAM to be reported as a portfolio company in the schedule of investments rather than as a consolidated subsidiary in the Company's financial results. The Company made an equity investment of $3,816 into IHAM in June 2009. As of December 31, 2011, the Company's total investment in IHAM at fair value was $194,597, including unrealized appreciation of $81,721. As of December 31, 2010, the Company's total investment in IHAM at fair value was $136,235, including unrealized appreciation of $32,777. For the years ended December 31, 2011, 2010 and 2009, the Company received distributions from IHAM of $19,048, $12,154 and $3,120, respectively. The distributions for the years ended December 31, 2011, 2010 and 2009 included dividend income of $19,048, $7,320 and $2,390, respectively.

        Ivy Hill I primarily invests in first and second lien bank debt of middle-market companies. Ivy Hill I was initially funded with $404,000 of capital including a $56,000 investment by the Company, consisting of $40,000 of Class B notes and $16,000 of subordinated notes. For the years ended December 31, 2011, 2010 and 2009, the Company earned $4,879, $6,859 and $5,742, respectively, from its investments in Ivy Hill I.

        Ivy Hill I purchased investments from the Company of $24,428 and $12,000, during the years ended December 31, 2011 and 2010, respectively, and may from time to time purchase additional

        In December 2009, the Company made an additional cash investment of approximately $33,000 in IHAM to facilitate IHAM's acquisition of Allied Capital's management rights in respect of, and interests in, the Allied Capital Senior Debt Fund, L.P. (now referred to as Ivy Hill Senior Debt Fund, L.P. (and related vehicles) "Ivy Hill SDF").

("Knightsbridge 2007-1") and Knightsbridge CLO 2008-1, Limited (now referred to as Ivy Hill Middle Market Credit Fund III, Ltd.) ("Knightsbridge Funds"). At the time, the Company also acquired from Allied Capital certain debt investments of the Knightsbridge Funds for approximately $52,000. During the year ended December 31, 2011, the Company's investments in the Knightsbridge Funds were repaid or sold resulting in a realized gain of $4,978. The Knightsbridge Funds purchased $25,448 of investments from the Company during the year ended December 31, 2011. A realized loss of $279 was recorded on these transactions for the year ended December 31, 2011.

Corporation for $7,900. This amount represented the fair value of those management rights and related management fees receivable as of the date of the sale. A realized gain of $5,882 was recognized on this transaction.

A realized loss of $495 was recorded on these transactions for the year ended December 31, 2011.

        In addition to the Ivy Hill Funds and Knightsbridge 2007-1, IHAM also serves as the sub-adviser/sub-manager to four other vehicles: CoLTS 2005-1 Ltd., CoLTS 2005-2 Ltd., CoLTS 2007-1 Ltd. (collectively, the "CoLTS Funds") and FirstLight Funding I, Ltd. ("FirstLight"), which is affiliated with the Company's portfolio company, Firstlight Financial Corporation.

        Beginning in November 2008, IHAM was party to a separate services agreement, referred to herein as the "services agreement," with Ares Capital Management. Pursuant to the services agreement, Ares Capital Management provided IHAM with office facilities, equipment, clerical, bookkeeping and record keeping services, services of investment professionals and others to perform investment advisory, research and related services, services of, and oversight of, custodians, depositories, accountants, attorneys, underwriters and such other persons in any other capacity deemed to be necessary. Under the services agreement, IHAM reimbursed Ares Capital Management for all of the actual costs associated with such services, including Ares Capital Management's allocable portion of overhead and the cost of its officers and respective staff in performing its obligations under the services agreement. The services agreement was terminated effective June 30, 2010 and replaced with a different services agreement with similar terms between IHAM and the Company's administrator.

17.   ALLIED ACQUISITION

        On April 1, 2010, the Company completed the Allied Acquisition by acquiring the outstanding shares of Allied Capital in exchange for shares of our common stock in a transaction valued at approximately $908 million as of the closing date. Concurrently with the completion of the Allied Acquisition, we repaid in full the $137 million of remaining principal amounts outstanding on Allied Capital's $250 million senior secured term loan. We also assumed all of Allied Capital's other outstanding debt obligations, including approximately $745 million in aggregate principal amount outstanding of the Allied Unsecured Notes.

        Under the terms of the Allied Acquisition each Allied Capital stockholder received 0.325 shares of our common stock for each share of Allied Capital common stock then owned by such stockholder. In connection with the Allied Acquisition, approximately 58.5 million shares of our common stock (including the effect of outstanding in-the money Allied Capital stock options) were issued to Allied Capital's then-existing stockholders, resulting in our then-existing stockholders owning approximately 69% of the combined company and the then-existing Allied Capital stockholders owning approximately 31% of the combined company.

        The Allied Acquisition was accounted for in accordance with the acquisition method of accounting as detailed in ASC 805-10 (previously SFAS No. 141(R)), Business Combinations. The acquisition method of accounting requires an acquirer to recognize the assets acquired, the liabilities assumed and any noncontrolling interest in the acquired entity based on their fair values as of the date of acquisition. As described in more detail in ASC 805-10, if the total acquisition date fair value of the

F-86

---

identifiable net assets acquired exceeds the fair value of the consideration transferred, the excess will be recognized as a gain. Upon completion of our determination of the fair value of Allied Capital's identifiable net assets as of April 1, 2010, the fair value of such net assets exceeded the fair value of the consideration transferred, resulting in the recognition of a gain. The valuation of the investments acquired as part of the Allied Acquisition was done in accordance with Ares Capital's valuation policy (see Notes 2 and 8).

        Set forth below is the allocation of the purchase price to the assets acquired and liabilities assumed in connection with the Allied Acquisition:

        The following pro forma condensed combined financial information does not purport to be indicative of actual financial position or results of our operations had the Allied Acquisition actually been consummated at the beginning of each period presented. Certain one-time charges have been eliminated. For year ended December 31, 2010, we recognized $19,833 in professional fees and other costs related to the Allied Acquisition. The pro forma adjustments reflecting the allocation of the purchase price of Allied Capital and the gain of $195,876 recognized on the Allied Acquisition have been eliminated from all periods presented. The pro forma condensed combined financial information does not reflect the potential impact of possible synergies and does not reflect any impact of additional accretion which would have been recognized on the transaction, except for that which was recorded after the transaction was consummated on April 1, 2010.

        Prior to the completion of the Allied Acquisition we purchased $340 million of assets from Allied Capital in arm's length transactions. Additionally, during the same period of time, IHAM purchased $69 million of assets from Allied Capital, also in arm's length transactions.

18.   LITIGATION

        The Company is party to certain lawsuits in the normal course of business. In addition, Allied Capital was involved in various legal proceedings which the Company assumed in connection with the Allied Acquisition. Furthermore, third parties may try to seek to impose liability on the Company in connection with the activities of its portfolio companies. While the outcome of any such legal proceedings cannot at this time be predicted with certainty, the Company does not expect that these legal proceedings will materially affect its business, financial condition or results of operations.

19.   SUBSEQUENT EVENTS

        The Company's management has evaluated subsequent events through the date of issuance of the consolidated financial statements included herein. There have been no subsequent events that occurred during such period that would require disclosure in this Form 10-K or would be required to be recognized in the Consolidated Financial Statements as of and for the year ended December 31, 2011, except as disclosed below.

        In January 2012, Ares Capital and Ares Capital CP amended the Revolving Funding Facility to, among other things, (i) extend the reinvestment period by one year to January 18, 2015, (ii) extend the maturity date by one year to January 18, 2017, and (iii) replace the pricing grid with an applicable spread over LIBOR of 2.50% and an applicable spread over "base rate" of 1.50%.

        In January 2012, we established, through our wholly owned subsidiary Ares Capital JB Funding LLC ("ACJB LLC"), a revolving funding facility (the "SMBC Funding Facility") by entering into a Loan and Servicing Agreement (the "SMBC Loan and Servicing Agreement") with ACJB LLC, as the borrower, Sumitomo Mitsui Banking Corporation ("SMBC"), as the administrative agent, collateral agent, and lender, pursuant to which SMBC has agreed to extend credit to ACJB LLC in an aggregate principal amount up to $200 million at any one time outstanding. In connection with the SMBC Funding Facility, we entered into a Purchase and Sale Agreement with ACJB LLC, pursuant to which we may sell ACJB LLC certain first lien loans we have originated or acquired, or will originate or acquire (the "SMBC Loans") from time to time. The SMBC Funding Facility is a revolving funding facility with a reinvestment period ending January 20, 2015 and a final maturity date of January 20, 2020. The reinvestment period and final maturity are both subject to two one-year extensions by mutual agreement. Subject to certain exceptions, the interest rate charged on the SMBC Funding Facility is based on LIBOR plus 2.125% (with no floor) or a "base rate" (which is the greater of a prime rate and the federal funds rate plus 0.50%) plus 1.125% (with no floor). The SMBC Loan and Servicing Agreement includes usual and customary events of default for revolving funding facilities of this nature, including allowing SMBC, upon a default, to accelerate and foreclose on the SMBC Loans and to pursue the rights under the SMBC Loans directly with the obligors thereof.

        In January 2012, we completed a public add-on equity offering (the "January 2012 Offering") through which we sold 16,422 shares of common stock at a net price of $15.41 per share. Total proceeds from the January 2012 Offering, net of underwriting discounts and commissions and estimated offering expenses payable by us, were approximately $252.5 million.

        In February 2012, we issued $143,750 aggregate principal amount of senior unsecured notes that mature on February 15, 2022 (the "2022 Notes"). The 2022 Notes mature on February 15, 2022 and may be redeemed in whole or in part at any time or from time to time at our option on or after February 15, 2015 at a par redemption price of $25 per security plus accrued and unpaid interest. The principal amount of the 2022 Notes will be payable at maturity. The 2022 Notes bear interest at a rate of 7.00% per year payable quarterly commencing on May 15, 2012. Total proceeds from the issuance of the 2022 Notes, net of underwriting discounts and offering costs, were approximately $138,338.

        We used the net proceeds of the January 2012 Offering and the issuance of the 2022 Notes to repay outstanding indebtedness under the Revolving Credit Facility and the Revolving Funding Facility.
