PROXY STATEMENT

ANNUAL MEETING OF SHAREHOLDERS

JUNE 22, 2018

This Proxy Statement is furnished in connection with the solicitation of proxies on behalf of the Board of Trustees of NexPoint Strategic Opportunities Fund, a Delaware statutory trust (formerly, NexPoint Credit Strategies Fund) (the “Fund”), for use at the Fund’s Annual Meeting of Shareholders to be held at 200 Crescent Court, Crescent Club, Hickory Room, Dallas, Texas 75201, on Friday, June 22, 2018, at 8:00 a.m. Central Time, and at any and all adjournments or postponements thereof (the “Annual Meeting”), for the purposes set forth in the accompanying Notice of Annual Meeting of Shareholders dated May 25, 2018. The Fund is a closed-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). NexPoint Advisors, L.P., a Delaware limited partnership (“NexPoint” or the “Adviser”), with its principal office at 200 Crescent Court, Suite 700, Dallas, Texas 75201, serves as the investment adviser and the administrator to the Fund. The Fund’s principal executive office is located at 200 Crescent Court, Suite 700, Dallas, Texas 75201.

This Proxy Statement and the accompanying Notice of Annual Meeting of Shareholders and form of proxy are being provided to shareholders on or about May 25, 2018. The Board of Trustees (the “Board”) has fixed the close of business on May 21, 2018 as the record date (the “Record Date”) for the determination of shareholders entitled to receive notice of, and to vote at, the Annual Meeting. As of the Record Date, 22,792,781 shares of the Fund’s common shares (“Common Shares”), par value $0.001 per share, were issued and outstanding, and the Fund had not issued any preferred shares. Shareholders of the Fund are entitled to one vote for each Fund share held and fractional votes for each fractional Fund share held.

If the form of proxy is properly executed and returned in time to be voted at the Annual Meeting, the shares covered thereby will be voted at the Annual Meeting in accordance with the instructions marked thereon. All properly executed proxies received by the Board that do not specify how shares should be voted will be voted “FOR” the election as a Trustee of the nominees listed in the Proposal, and in the discretion of the persons named as proxies in connection with any other matter which may properly come before the Annual Meeting or any adjournment or postponements thereof.

The Board does not know of any matters to be considered at the Annual Meeting other than the election of the Trustees referred to in this Proxy Statement. A shareholder may revoke his or her proxy by appearing at the Annual Meeting, revoking his or her proxy and voting in person, giving written notice of such revocation to the Secretary of the Fund or by returning a later-dated proxy before the Annual Meeting.

The presence in person or by proxy of the holders of a majority of the shares of the Fund entitled to vote shall constitute a quorum (“Quorum”) for the Fund’s Annual Meeting. If a Quorum is not present at the Annual Meeting, or if a Quorum is present but sufficient votes to approve the Proposal are not received, the persons named as proxies may propose one or more adjournments or postponements of the Annual Meeting to permit further solicitation of proxies. Any adjournment or postponement will require the affirmative vote of a majority of those shares that are represented at the Annual Meeting in person or by proxy, whether or not a Quorum is present.

1

Shares represented by properly executed proxies with respect to which (i) a vote is withheld, (ii) the shareholder abstains, or (iii) a broker does not vote (i.e., “broker non-votes”) will be treated as shares that are present and entitled to vote for purposes of determining a Quorum. Assuming the presence of a Quorum, abstentions and “broker non-votes” will have no effect on the outcome of the vote on the Proposal.

In addition to soliciting proxies by mail, the Fund’s officers and employees of the Adviser may solicit proxies by web, by telephone or in person. Copies of the Notice for the Annual Meeting, the Proxy Statement and the form of proxy are available at www.proxyonline.com/docs/nexpointsof2018.pdf. The Fund has engaged AST Fund Solutions, LLC, at AST Fund Solutions, ATTN: NexPoint 12563 Fulfillment, 55 Challenger Road, Suite 201, Ridgefield Park, New Jersey 07660 for inquiries, to provide shareholder meeting services, including the distribution of this Proxy Statement and related materials to shareholders as well as assisting the Fund in soliciting proxies for the Annual Meeting at an approximate cost of $55,000. The costs of proxy solicitation and expenses incurred in connection with preparing this Proxy Statement and its enclosures will be paid by the Fund.

PROPOSAL 1

ELECTION OF TRUSTEES

The Fund’s Board is currently composed of six Trustees, five of whom are not “interested persons” of the Fund (as defined in the 1940 Act) (the “Independent Trustees”). The Independent Trustees of the Board are Bryan A. Ward, Timothy K. Hui, Ethan Powell, John Honis and Dr. Bob Froehlich. Dustin Norris is deemed to be an “interested person” of the Fund under the 1940 Act because of his affiliation with NexPoint, the investment adviser for the Fund. At the Annual Meeting, the holders of the Fund’s Common Shares are being asked to re-elect John Honis and to elect Dustin Norris as Class III Trustees of the Fund, to serve for a three-year term until the 2021 annual meeting of shareholders or until his respective successor is duly elected and qualified. Mr. Honis is currently serving as a Class III Trustee of the Fund and has agreed to continue to serve as a Class III Trustee, if re-elected. If Messrs. Honis and Norris are not available for re-election and election, respectively, at the time of the Annual Meeting, the persons named as proxies will vote for such substitute nominee(s) as the Fund’s Governance Committee may select.

The Fund’s Board is divided into three classes with the term of office of one class expiring each year. John Honis is currently serving as a Class III Trustee and was last elected to serve a three year term at the Fund’s annual meeting of shareholders held on June 5, 2015. Dustin Norris was appointed to serve as a Trustee of the Fund at a Meeting of the Board held on February 7, 2018. Ethan Powell and Bryan A. Ward are currently serving as Class I Trustees. Messrs. Powell and Ward were last elected to serve until the 2019 annual meeting of shareholders at the Fund’s annual meeting of shareholders held on June 3, 2016. Dr. Bob Froehlich and Timothy K. Hui are currently serving as a Class II Trustees. Dr. Froehlich and Mr. Hui were last elected to serve until the 2020 annual meeting of shareholders at the Fund’s annual meeting of shareholders held on June 2, 2017. Mr. Honis will continue to serve as a Class III Trustee if re-elected at the Annual Meeting. The Fund’s Trustees are not required to attend the Fund’s annual shareholder meetings. However, all Trustees attended the Fund’s annual meeting of shareholders held on June 2, 2017.

Vote Required for Election of Trustees

For a Class III Trustee of the Fund, the election requires the affirmative vote of the holders of a majority of the Common Shares of the Fund, represented in person or by proxy at the Annual Meeting and entitled to vote for the election of a Trustee. Abstentions and “broker non-votes” (i.e., shares held in “street name” by brokers or nominees that indicate on their proxies that they do not have discretionary authority to vote such shares as to the election of a Trustee) are counted as present at the Annual Meeting but, assuming the presence of a Quorum, will have no effect on the outcome of the vote on the Proposal.

THE BOARD, INCLUDING ALL OF THE INDEPENDENT TRUSTEES, UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS VOTE “FOR” THE ELECTION OF THE NOMINEES AS TRUSTEES.

Qualifications and Additional Information about each Nominee for Trustee and the Continuing Trustees

The following provides an overview of the considerations that led the Board to conclude that each individual nominee for Trustee or the individuals serving as continuing Trustees of the Fund should be nominated or so serve, as well as each nominee’s and each Trustee’s name and certain biographical information as reported by them to the Fund. Among the factors the Board considered when concluding that an individual should be a nominee for Trustee or serve on the Board were the following: the individual’s experience, skills, expertise, education, knowledge, diversity, personal and professional integrity, character, business judgment, time availability in light of other commitments, dedication, the candidate’s ability to qualify as an Independent Trustee and the existence of any other relationships that might give rise to a conflict of interest and other relevant factors that the Fund’s Governance Committee considers appropriate in the context of the needs of the Board (e.g., whether a candidate is an “audit committee financial expert” under the federal securities laws).

In respect of each Trustee nominee and each continuing Trustee, the individual’s professional accomplishments and prior experience, including, in some cases, in fields related to the operations of the Fund, were a significant factor in the determination that the individual should be a nominee for Trustee or serve as a Trustee of the Fund. Each Trustee nominee’s and each continuing Trustee’s professional experience and additional considerations that contributed to the Board’s conclusion that an individual should serve on the Board are summarized in the table below.

Information about the Fund’s Executive Officers

Set forth below are the names and certain information regarding the Fund’s executive officers. Such officers serve at the pleasure of the Trustees or until their successors have been duly elected and qualified. The Trustees may fill any vacancy in office or add any additional officers at any time.

Set forth in the table below is the security ownership in the Fund of each Trustee and executive officer.

As of February 28, 2018, the Trustees and officers of the Fund as a group owned 15.61% of the Fund’s outstanding Common Shares, including shares of the Common Stock directly owned by the Adviser over which Mr. Dondero controls through his control of NexPoint Advisors GP, LLC, the general partner of the Adviser.

As of February 28, 2018, none of the Independent Trustees or their immediate family members owned beneficially or of record any securities issued by the Adviser, the principal underwriter, or any person controlling, controlled by, or under common control with the Adviser or principal underwriter.

Role of the Board of Trustees, Leadership Structure and Risk Oversight

The Role of the Board of Trustees

The Board oversees the management and operations of the Fund. Like most registered investment companies, the day-to-day management and operation of the Fund is performed by various service providers to the Fund, such as

11

the Adviser, and the distributor, administrator, custodian, and transfer agent. The Board has appointed senior employees of certain of these service providers as officers of the Fund, with responsibility to monitor and report to the Board on the Fund’s operations. The Board receives regular reports from these officers and service providers regarding the Fund’s operations. For example, the Treasurer provides reports as to financial reporting matters and investment personnel report on the performance of the Fund. The Board has appointed a Chief Compliance Officer who administers the Fund’s compliance program and regularly reports to the Board as to compliance matters. Some of these reports are provided as part of formal in-person Board meetings, which are typically held quarterly, in person, and involve the Board’s review of, among other items, recent Fund operations. The Board also periodically holds telephonic meetings as part of its review of the Fund’s activities. From time to time one or more members of the Board may also meet with management in less formal settings, between scheduled Board meetings, to discuss various topics. In all cases, however, the role of the Board and of any individual Trustee is one of oversight and not of management of the day-to-day affairs of the Fund and its oversight role does not make the Board a guarantor of the Fund’s investments, operations or activities.

Board Structure and Leadership

The Board has structured itself in a manner that it believes allows it to perform its oversight function effectively. The Board currently consists of six Trustees, five of whom are not “interested persons,” as defined in the 1940 Act and are “independent” as defined in Rule 303A.02 of the New York Stock Exchange Listed Company Manual. The remaining Trustee, Mr. Norris, is currently treated as an “interested person” of the Fund (an “Interested Trustee”). Mr. Norris is treated as an Interested Trustee because of his position with HCMFA, an affiliate of the Adviser. Mr. Powell serves as Chairman of the Board. The Trustees meet periodically throughout the year in person and by telephone to oversee the Fund’s activities, review contractual arrangements with service providers for the Fund and review the Fund’s performance. During the fiscal year ended December 31, 2017, the Board convened ten times. Each Trustee attended at least 75% of the aggregate of the total number of meetings of the Board and Committees on which he served during the periods that he served. The Fund encourages, but does not require, Trustees to attend the Annual Meeting. However, all Trustees attended the Fund’s annual meeting of shareholders held on June 2, 2017.

The Board periodically reviews its leadership structure, including the role of the Chairman. The Board also completes an annual self-assessment during which it reviews its leadership and Committee structure and considers whether its structure remains appropriate in light of the Fund’s current operations. The Board believes that its leadership structure, including the current percentage of the Board who are Independent Trustees is appropriate given its specific characteristics. These characteristics include: (i) the extent to which the work of the Board is conducted through the standing committees, each of whose meetings are chaired by an Independent Trustee; (ii) the extent to which the Independent Trustees meet as needed, together with their independent legal counsel, in the absence of members of management and any member of the Board who is considered an “interested person” of the Fund; and (iii) Mr. Powell’s and Mr. Honis’ previous positions with affiliates of the Adviser, which enhances the Board’s understanding of the operations of the Adviser.

Board Oversight of Risk Management. The Board’s role is one of oversight, rather than active management. This oversight extends to the Fund’s risk management processes. These processes are embedded in the responsibilities of officers of, and service providers to, the Fund. For example, the Adviser and other service providers to the Fund are primarily responsible for the management of the Fund’s investment risks. The Board has not established a formal risk oversight committee. However, much of the regular work of the Board and its standing Committees addresses aspects of risk oversight. For example, the Trustees seek to understand the key risks facing the Fund, including those involving conflicts of interest; how management identifies and monitors these risks on an ongoing basis; how management develops and implements controls to mitigate these risks; and how management tests the effectiveness of those controls.

In the course of providing that oversight, the Board receives a wide range of reports on the Fund’s activities from the Adviser and other service providers, including reports regarding the Fund’s investment portfolio, the

12

compliance of the Fund with applicable laws, and the Fund’s financial accounting and reporting. The Board also meets periodically with the Fund’s Chief Compliance Officer to receive reports regarding the compliance of the Fund with the federal securities laws and the Fund’s internal compliance policies and procedures and meets with the Fund’s Chief Compliance Officer periodically, including at least annually, to review the Chief Compliance Officer’s annual report, including the Chief Compliance Officer’s risk-based analysis for the Fund. The Board’s Audit and Qualified Legal Compliance Committee (the “Audit Committee”) also meets regularly with the Treasurer and the Fund’s independent registered public accounting firm to discuss, among other things, the internal control structure of the Fund’s financial reporting function. The Board also meets periodically with the portfolio managers of the Fund to receive reports regarding the management of the Fund, including its investment risks.

The Board recognizes that not all risks that may affect the Fund can be identified, that it may not be practical or cost-effective to eliminate or mitigate certain risks, that it may be necessary to bear certain risks (such as investment-related risks) to achieve the Fund’s goals, that reports received by the Trustees with respect to risk management matters are typically summaries of the relevant information, and that the processes, procedures and controls employed to address risks may be limited in their effectiveness. As a result of the foregoing and other factors, risk management oversight by the Board and by the Committees is subject to substantial limitations.

Committees of the Board

The Board conducts much of its work through certain standing Committees. The Board has five Committees, the Audit and Qualified Legal Compliance Committee, the Governance Committee, the Compliance Committee, the Distribution Oversight Committee and the Alternatives Oversight Committee, which are discussed in greater detail below. The Board has adopted charters for each of these committees.

The Audit and Qualified Legal Compliance Committee. The members of the Audit Committee are Dr. Froehlich and Messrs. Hui and Ward, each of whom is independent for purposes of the 1940 Act. The Audit Committee is responsible for approving the Fund’s independent accountants, reviewing with the Fund’s independent accountants the plans and results of the audit engagement and the adequacy of the Fund’s internal accounting controls and approving professional services provided by the Fund’s independent accountants. The Audit Committee is charged with compliance with Rules 205.2(k) and 205.3(c) of Title 17 of the Code of Federal Regulations regarding alternative reporting procedures for attorneys representing the Fund who appear and practice before the SEC on behalf of the Fund. The Audit Committee is also responsible for reviewing and overseeing the valuation of debt and equity securities that are not publicly traded or for which current market values are not readily available pursuant to policies and procedures adopted by the Board. The Board and Audit Committee will use the services of one or more independent valuation firms to help them determine the fair value of these securities. In addition, each member of the Audit Committee meets the current independence and experience requirements of Rule 10A-3 under the Exchange Act.

The Audit Committee met six times during the fiscal year ended December 31, 2017. Mr. Ward acts as the Chairman of the Audit Committee and as the audit committee financial expert.

The Governance Committee. The Fund’s Governance Committee’s function is to oversee and make recommendations to the full Board or the Independent Trustees, as applicable, with respect to the governance of the Fund, selection and nomination of Trustees, compensation of Trustees, and related matters. The Governance Committee is also responsible for at least annually evaluating each Trustee and determining whether to recommend each Trustee’s continued service in that capacity. The Governance Committee will consider recommendations for Trustee nominees from shareholders sent to the Secretary of the Trust, 200 Crescent Court, Suite 700, Dallas, Texas 75201. A nomination submission must include all information relating to the recommended nominee that is required to be disclosed in solicitations or proxy statements for the election of Trustees, as well as information sufficient to evaluate the recommended nominee’s ability to meet the responsibilities of a Trustee of the Fund. Nomination submissions must be accompanied by a written consent of

13

the individual to stand for election if nominated by the Board and to serve if elected by the shareholders, and such additional information must be provided regarding the recommended nominee as reasonably requested by the Governance Committee. The Governance Committee is currently comprised of Messrs. Hui, Ward and Powell, each of whom is independent for purposes of the 1940 Act. Mr. Powell serves as the Chairman of the Governance Committee. The Governance Committee met five times during the fiscal year ended December 31, 2017.

The Compliance Committee. The Compliance Committee’s function is to oversee and assist Board oversight of the Fund’s compliance with legal and regulatory requirements and to seek to address any potential conflicts of interest between the Fund and NexPoint in connection with any potential or existing litigation or other legal proceeding relating to securities held by the Fund and the Adviser or another client of the Adviser. The Compliance Committee is currently comprised of Dr. Froehlich and Messrs. Hui and Powell. Mr. Hui acts as the Chairman of the Compliance Committee. The Compliance Committee met two times during the fiscal year ended December 31, 2017.

The Distribution Oversight Committee. The members of the Distribution Oversight Committee are Dr. Froehlich and Mr. Honis. The Distribution Oversight Committee is responsible for reviewing arrangements with financial intermediaries who provide service to the Fund, including Fund payments to financial intermediaries. Dr. Froehlich serves as Chairman of the Distribution Oversight Committee. The Distribution Oversight Committee met two times during the fiscal year ended December 31, 2017.

The Alternatives Oversight Committee. The members of the Alternatives Oversight Committee are Messrs. Honis and Ward. The Alternatives Oversight Committee is responsible for overseeing any funds that in the Board’s determination employ alternative investment strategies. Mr. Honis serves as Chairman of the Alternatives Oversight Committee. The Alternatives Oversight Committee met two times during the fiscal year ended December 31, 2017.

Remuneration of Trustees and Executive Officers

The executive officers of the Fund and those of its Trustees who are “interested persons” (as defined in the Investment Company Act) of the Fund receive no direct remuneration from the Fund. Each Independent Trustee receives an annual retainer of $150,000 payable in quarterly installments and allocated among each portfolio in the Fund Complex based upon relative net assets. The Independent Trustees are reimbursed for actual out-of-pocket expenses relating to attendance at meetings. The Independent Trustees do not receive any separate compensation in connection with service on Committees or for attending Board or Committee Meetings. The Trustees do not have any pension or retirement plan.

The following table summarizes the compensation paid by the Fund to its Trustees and the aggregate compensation paid by the Fund Complex to the Trustees for services rendered in the fiscal year ended December 31, 2017.

14

Share Ownership and Certain Beneficial Owners

To the knowledge of management of the Fund and the Board, the following shareholder(s) or “groups,” as the term is defined in Section 13(d) of the 1934 Act, beneficially owned, or were owners of record of, more than 5% of the Fund’s outstanding shares as of May 21, 2018:

15

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the 1934 Act and Section 30(h) of the 1940 Act, and the rules thereunder, require that the Fund’s Trustees and officers, the Adviser, certain persons affiliated with the Adviser, and persons who own beneficially, directly or indirectly, more than 10% of the Fund’s outstanding interests (collectively, “Section 16 reporting persons”), file initial reports of beneficial ownership and reports of changes in beneficial ownership of Fund interests with the SEC and the New York Stock Exchange. Section 16 reporting persons are required by SEC regulations to furnish to the Fund copies of all Section 16(a) forms they file with respect to shares of the Fund. Based solely on a review of copies of such reports of ownership, as of the date of the Proxy Statement, the Fund is aware of one late Form 4 that was filed on June 5, 2017 for James Dondero, President and Principal Executive Officer of the Fund. The Fund believes that, in all other instances during the past fiscal year, the Officers, Trustees and greater than 10% beneficial holders of the Fund complied with all applicable filing requirements.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

At a meeting held on December 7-8, 2017, the Fund’s Audit Committee approved, and the Fund’s Board, including a majority of the Independent Trustees, ratified the selection of, PricewaterhouseCoopers LLP (“PwC”) as the Fund’s independent registered public accounting firm for the fiscal year ending December 31, 2018. Representatives of PwC will not be present at the Annual Meeting. After reviewing the Fund’s audited financial statements for the fiscal year ended December 31, 2017, the Fund’s Audit Committee recommended to the Fund’s Board that such statements be included in the Fund’s Annual Report to Shareholders for the fiscal year ended December 31, 2017. A copy of the Audit Committee’s report appears below.

Independent Registered Public Accounting Firm Fees and Services

The following chart reflects fees paid to PwC in the Fund’s last two fiscal years. One hundred percent (100%) of all services provided by PwC to the Fund in each year were pre-approved and no fees were subject to pre-approval by the Audit Committee pursuant to Rule 2-01(c)(7)(i)(c) of Regulation S-X. The audit services are approved by the Audit Committee pursuant to an audit engagement letter, and, in accordance with the Fund’s pre-approval policies and procedures, the Audit Committee of the Fund must pre-approve all non-audit services provided by PwC, and all non-audit services provided by PwC to the Adviser, or any entity controlling, controlled by, or under common control with the Adviser that provides ongoing services to the Fund that are related to the operations and financial reporting of the Fund. In some circumstances, when certain services were not recognized at the time of the engagement to be non-audit services, the pre-approval requirement may be

16

waived if the aggregate amount of the fees for such non-audit services constitutes less than five percent of the total amount of revenues paid to PwC by the Fund during the fiscal year in which the non-audit services are provided. PwC provided non-audit services to the Adviser during the Fund’s last two fiscal years, but these services did not relate directly to the operations and financial reporting of the Fund, and therefore were not subject to pre-approval pursuant to Rule 2-01(c)(7)(ii) of Regulation S-X. PwC did not provide any non-audit services to any entity controlling, controlled by or under common control with the Adviser that provides ongoing services to the Fund. The Audit Committee has considered whether the provision of non-audit services that were rendered to the Adviser is compatible with maintaining PwC’s independence.

Audit Fees. Audit fees consist of fees billed for professional services rendered for the audit of the Fund’s year-end consolidated financial statements and reviews of the interim consolidated financial statements included in quarterly reports and services that are normally provided by PwC in connection with statutory and regulatory filings. These services also include the required audits of the Fund’s internal controls over financial reporting.

Audit-Related Fees. Audit-related fees consist of fees billed for assurance and related services that are reasonably related to the performance of the audit or review of the Fund’s consolidated financial statements and are not reported under “Audit Fees.” These services include attestation services that are not required by statute or regulation, consultations concerning financial accounting and reporting standards, and fees related to requests for documentation and information from regulatory and other government agencies.

Tax Fees. Tax fees consist of fees billed for professional services for tax compliance. These services include assistance regarding federal, state, and local tax compliance.

All Other Fees. All other fees include fees for products and services other than the services reported above.

Report of the Audit Committee

The Audit Committee oversees the Fund’s accounting and financial reporting processes and the audits of the Fund’s financial statements. Management is responsible for the preparation, presentation and integrity of the Fund’s financial statements, the Fund’s accounting and financial and reporting principles, and internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. The Audit Committee reviewed the audited financial statements in the Annual Report dated December 31, 2017 with management and discussed the quality of the accounting principles, the reasonableness of significant judgments and the clarity of disclosures in the financial statements.

The Audit Committee has considered and discussed the above described December 31, 2017 audited financial statements with management and with PwC. The Audit Committee has also discussed with PwC the matters required to be discussed by the statement on Auditing Standards No. 1301, as amended (AICPA, Professional Standards, Vol. 1. AU section 380), as adopted by the Public Company Accounting Oversight Board (“PCAOB”) in Rule 3200T, The Auditor’s Communication With Those Charged With Governance. The Audit Committee

17

reviewed with PwC, who is responsible for expressing an opinion on the conformity of those audited financial statements with generally accepted accounting principles, their judgment as to the quality, not just the acceptability, of the Fund’s accounting principles and such other matters as are required to be discussed with the Audit Committee under generally accepted auditing standards. Finally, the Audit Committee reviewed the written disclosures and the letters from PwC required by PCAOB Rule 3526, Communication with Audit Committees Concerning Independence, as currently in effect, has considered whether the provision of other non-audit services by PwC to the Fund are compatible with maintaining PwC’s independence, and has discussed with PwC its independence of the Fund.

The Audit Committee discussed with PwC the overall scope and plans for the audit. The Audit Committee met with PwC to discuss the results of their audit, their evaluations of the Fund’s internal controls and the overall quality of the Fund’s financial reporting.

Based upon the reports and discussions described in this report, and subject to the limitations on the role and responsibilities of the Audit Committee referred to in this proxy statement and in the Audit Committee’s Charter, the Audit Committee recommended to the Board (and the Board has approved) that the Fund’s audited financial statements be included in the Annual Report to Shareholders for the fiscal year ended December 31, 2017 and filed with the SEC.

Shareholders are reminded, however, that the members of the Audit Committee are not professionally engaged in the practice of auditing or accounting. Members of the Audit Committee rely, without independent verification, on the information provided to them and on the representations made by management and PwC. Accordingly, the Audit Committee’s oversight does not provide an independent basis to determine that management has maintained appropriate accounting and financial reporting principles or appropriate internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. Furthermore, the Audit Committee’s considerations and discussions, referred to above, do not assure that the audit of the Fund’s financial statements has been carried out in accordance with the standards of the PCAOB, that the financial statements are presented in conformity with accounting principles generally accepted in the United States of America or that the Fund’s independent registered public accounting firm is, in fact, “independent.”

in the proxy materials does not guarantee that it will be included. Any proposals submitted after such date will not be included in the Fund’s proxy statement and proxy card relating to the 2019 Annual Meeting of Shareholders. Proxies solicited by the Fund will confer discretionary voting authority with respect to these proposals if the proposals are not received by the Fund, in good order and complying with all applicable legal requirements, by March 24, 2019, and may confer discretionary voting authority with respect to proposals received before such date, in each case subject to SEC rules governing the exercise of this authority.

Delivery Requirements

The SEC has adopted rules that permit companies and intermediaries such as brokers to satisfy delivery requirements for proxy statements with respect to two or more shareholders sharing the same address by delivering a single proxy statement or Notice of Internet Availability of Proxy Materials (“Notice”) addressed to those shareholders or by sending separate Notices for each household account in a single envelope. This process, which is commonly referred to as “householding,” potentially provides extra convenience for shareholders and cost savings for companies. The Fund and some brokers household proxy materials or Notices, delivering a single proxy statement or Notice to multiple shareholders sharing an address unless contrary instructions have been received from the affected shareholders. Once a shareholder has received notice from a broker or the Fund that they will be householding materials to the shareholder’s address, householding will continue until the shareholder is notified otherwise or until the shareholder revokes consent.

We will deliver promptly, upon request, a separate copy of any of these documents to shareholders at a shared address to which a single copy of such document(s) was delivered. Shareholders who wish to receive a separate copy of any of these documents, or to receive a single copy of such documents if multiple copies were delivered, now or in the future, should submit their request by writing to the Fund c/o NexPoint Advisors, L.P., 200 Crescent Court, Suite 700, Dallas, Texas 75201 or calling the Fund at (866) 351-4440.
