There are many factors that affect our business and the results of our operations, many of which are beyond our control. The risks described in this report are not the only risks facing our Company. 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.

Because of the significant percentage of our sales to certain customers, the loss of, or a substantial decline in sales to, a top customer could have a material adverse effect on our revenues and profitability.

For 2012, 2011 and 2010, we derived 53%, 59%, and 63% of our revenues from our five largest customers during these periods. These five customers in 2012 were Arrow Electronics, NEI Corporation, NEC Corporation, Nokia Siemens Networks and Philips Healthcare, each of which purchase a variety of products from us. During 2012, 2011 and 2010, revenues attributable to our largest customer. Nokia Siemens Networks, were 23%, 35% and 37%. Due to our significant customer concentration, our largest customers have additional pricing power over us that can adversely affect revenues, gross margins or cause us to exit lines of business with them that do not meet profitability objectives. Further, a financial hardship experienced by, or a substantial decrease in sales to, any one of these customers could materially affect our revenues and profitability. Generally, our products are components for our customers’ products and in certain instances our customers are not the end-users of our products. If any of these customers’ efforts to market the products we design and manufacture for them or the end products into which our products are incorporated are unsuccessful in the marketplace or if these customers experience a decrease in demand for such products, our design wins, sales and/or profitability will be significantly reduced. Furthermore, if these customers experience adverse economic conditions in the end markets into which they sell our products, we would expect a significant reduction in spending by these customers in addition to increasing our exposure to credit risk, which may limit our ability to collect. Some of these end markets are characterized by intense competition, rapid technological change and economic uncertainty and as such there is no guarantee that the revenues associated with the potential loss of a key customer will be replaced by the establishment of new business relationships. Our exposure to economic cyclicality and any related fluctuation in demand from these customers could have a material adverse effect on our revenues and financial condition.

We use one contract manufacturer to assemble certain Radisys products, and a loss or degradation in performance of our contract manufacturer could have a material adverse effect on our business or our profitability.

If our third party manufacturer fails to adequately perform, our revenues and profitability could be adversely affected. Among other things, inadequate performance by our contract manufacturer could include the production of products that do not meet our quality standards or schedule and delivery requirements and could cause us to manufacture products internally or seek additional sources of manufacturing. Additionally, our contract manufacturer may decide in the future to discontinue conducting business with us. If we are required to change contract manufacturer or assume internal manufacturing operations due to any termination of the agreements with our contract manufacturer, we may lose revenue, experience manufacturing delays, incur increased costs or otherwise damage our customer relationships. We cannot guarantee that we will be able to establish alternative manufacturing relationships on similar terms.

Additionally, if our contract manufacturer is responsible for patent or copyright infringement (including through the supply of counterfeit parts), we may or may not be able to hold them responsible and we may incur costs in defending claims or providing remedies. Such infringements may also cause our customers to abruptly discontinue selling the impacted products, which would adversely affect our net sales of those products, and could affect our customer relationships more broadly.

Our future performance depends in part on the research and development efforts of third parties.

We purchase technology from a number of third parties that is used in the development of new software and hardware products. If our third party vendors fail to adequately develop new products that meet our specifications, timelines and cost targets, our revenues and profitability could be adversely affected as we may be unable to meet our customer delivery commitments or maintain pace with the development efforts of our competitors.

Our ability, as well as our contract manufacturer's ability, to meet customer demand depends largely on our ability to obtain raw materials and a reduction or disruption in the availability of raw materials could negatively impact our business.

The recent global economic contraction has caused many of our component suppliers to reduce their manufacturing capacity. As the global economy improves, our component suppliers are experiencing and may continue to experience supply constraints until they expand capacity to meet increased levels of demand. These supply constraints may adversely affect the availability and lead times of components for our products. Increased lead times mean we may have to forsake flexibility in

aligning our supply to customer demand changes and increase our exposure to excess inventory since we may have to order material earlier and in larger quantities. Further, supply constraints will likely result in increased expedite and overall procurement costs as we attempt to meet customer demand requirements. In addition, these supply constraints may affect our ability, as well as our contract manufacturer's, ability to meet customer demand and thus result in missed sales opportunities and a loss of market share, negatively impacting revenues and our overall operating results.

Because of the limited number of direct, and indirect suppliers, or in some cases, one supplier, for some of the components we and our contract manufacturer use a loss of a supplier, a decline in the quality and/or a shortage in any of these components could have a material adverse effect on our business or our profitability.

There are only a limited number of direct and indirect suppliers, or in some cases, only one supplier, for a continuing supply of the components our contract manufacturer uses in the manufacturing of our products and any disruption in supply could adversely impact our financial performance. For example, we have some silicon that is solely sourced from large silicon producers. We obtain these components from resellers, integrators and component manufacturers. Alternative sources of components that are procured from one supplier or a limited number of suppliers could be difficult to locate and / or would require a significant amount of time and resources to establish. We have in the past experienced and may in the future experience difficulty obtaining adequate quantities of key components used in certain of our products, which have resulted and may result in delayed or lost sales. Delayed sales can also result from our silicon vendors delays or cancellations of new technologies and products as these technologies and products are often designed into new Radisys products before they are fully available from our suppliers. In addition, current economic conditions expose us to an increased risk of vendor insolvency, which, given our reliance upon a limited supply base, could result in an inability to procure adequate quantities of materials and components to meet our customers’ demand and/or ability to procure the quality of materials and components our customers require.

Political events, war, terrorism, public health issues, natural disasters and other circumstances could have a material adverse effect on our financial condition and operating results

War, terrorism, geopolitical uncertainties, public health issues, and other business interruptions have caused and could cause damage or disruption to international commerce and the global economy, and thus could have a strong negative effect on our business and our suppliers, logistics providers, manufacturing vendors and customers, including channel partners. Our business operations are subject to interruption by natural disasters, fire, power shortages, nuclear power plant accidents, terrorist attacks, and other hostile acts, labor disputes, public health issues, and other events beyond our control. Such events could decrease demand for our products, make it difficult or impossible for us to make and deliver products to our customers, including channel partners, or to receive components from our suppliers, and create delays and inefficiencies in our supply chain. Should major public health issues, including pandemics, arise, our business could be negatively affected by more stringent employee travel restrictions, additional limitations in freight services, governmental actions limiting the movement of products between regions, delays in production ramps of new products, and disruptions in the operations of our manufacturing vendors and component suppliers. The majority of our research and development activities and other critical business operations, including certain component suppliers and manufacturing vendors, are in locations that could be affected by natural disasters. In the event of a natural disaster, losses, significant recovery time and substantial expenditures could be required to resume operations and our financial condition and operating results could be materially adversely affected.

Our failure to develop and introduce new products on a timely basis could harm our ability to attract and retain customers.

Our industry is characterized by rapidly evolving technology, frequent product introductions and ongoing demands for greater performance and functionality. Therefore, we must continually identify, design, develop and introduce new and updated products with improved features to remain competitive. To introduce these products on a timely basis we must:


•	design innovative and performance-improving features that differentiate our products from those of our competitors;


•	identify emerging technological trends in our target markets, including new standards for our products in a timely manner;


•	accurately define and design new products to meet market needs;


•	anticipate changes in end-user preferences with respect to our customers’ products;


•	rapidly develop and produce these products at competitive prices;


•	anticipate and respond effectively to technological changes or product announcements by others; and


•	provide effective technical and post-sales support for these new products as they are deployed.

To remain competitive and stimulate customer demand, we must successfully manage the transition from 10G to 40G ATCA product technologies.

The telecommunications industry is in the process of transitioning from 10G to 40G ATCA technologies. We have introduced a suite of new products under the 40G ATCA standards to meet our customers' demands. The success of these new product introductions depends on a number of factors including but not limited to timely and successful product development, market acceptance, our ability to manage the risks associated with new products and production ramp issues, the availability of application software for new products, the effective management of purchase commitments and inventory levels in line with anticipated product demand, the availability of products in appropriate quantities and costs to meet anticipated demand, and the risk that new products may have quality or other defects in the early stages of introduction. Accordingly, we cannot determine in advance the ultimate effect of new product introductions and transitions on our financial condition and operating results.

We intend to develop new products and expand into new markets, which may not be successful and could harm our operating results.

We intend to expand into new markets and develop new products and applications based on our existing technologies integrated with new technologies organically developed or acquired. These efforts have required and will continue to require us to make substantial investments, including but not limited to significant research, development and engineering expenditures. Additionally, many of the new products and applications we are working on may take longer and more resources to develop and commercialize than originally anticipated. Specific risks in connection with expanding into new products and markets include, but are not limited to, the inability to transfer our quality standards and technology into new products, the failure of customers to accept our new products, longer product development cycles and competition and intellectual property disputes. We may not be able to successfully manage expansion into new markets and products and these unsuccessful efforts may harm our financial condition and operating results.

Our projections of future purchase orders, revenues and earnings are highly subjective and may not reflect future results which could negatively affect our financial results and cause volatility in the price of our common stock.

We have several contracts with most of our major customers but these contracts do not commit them to purchase a minimum amount of our products. These contracts generally require our customers to provide us with forecasts of their anticipated purchases. However, our experience indicates that customers can change their purchasing patterns quickly in response to market demands, changes in their management or strategy, among other factors, and therefore these forecasts may not be relied upon to accurately forecast sales. From time to time we provide projections to our shareholders and the investment community of our future sales and earnings. Since we do not have long-term purchase commitments from our major customers and the customer order cycle is short, it is difficult for us to accurately predict the amount of our sales and related earnings in any given period. Our projections are based on management’s best estimate of sales using historical sales data, information from customers and other information deemed relevant. These projections are highly subjective since sales to our customers can fluctuate substantially based on the demands of their customers and the relevant markets. Our period to period revenues have varied in the past and may continue to vary in the future.

Unanticipated reductions in purchase orders from our customers may also result in us having to write off excess or obsolete inventory. Conversely, if we underestimate customer demand or if insufficient manufacturing capacity is available or if our customers experience a financial hardship or if we experience unplanned cancellations of customer contracts, the current provision for inventory reserves may be inadequate and as a result we could forego revenue opportunities and potentially lose market share and damage our customer relationships. In addition and as stated above, we have a high degree of customer concentration. Any significant change in purchases by any one of our large customers may significantly affect our sales and profitability.

If demand for our products fluctuates, our revenues, profitability and financial condition could be adversely affected. Important factors that could cause demand for our products to fluctuate include:


•	changes in customer product needs;


•	changes in the level of customers’ inventory;


•	changes in business and economic conditions;


•	changes in the mix of products we sell; and


•	market acceptance of our products.

The price of our common stock may be adversely affected by numerous factors, such as general economic and market conditions, changes in analysts’ estimates regarding earnings as well as factors relating to the commercial systems and

communication networking markets in general. We cannot accurately forecast all of the above factors. As a result, we believe that period-to-period comparisons may not be indicative of future operating results. Our operating results in any future period may fall below the expectations of public market analysts or investors.

Our business depends on conditions in primary markets into which we sell our products. Demand in these markets can be cyclical and volatile, and any inability to sell products to these markets or forecast customer demand due to unfavorable or volatile market conditions could have a material adverse effect on our revenues and gross margin.

Generally, our products are components for our customers’ products and, in certain instances, our customers are not the end-users of our products. If our customers experience adverse economic conditions in the end markets into which they sell our products, we would expect a significant reduction in spending by our customers. Some of these end markets are characterized by intense competition, rapid technological change, consolidation of providers and economic uncertainty. Our exposure to economic cyclicality and any related fluctuation in customer demand in these end markets could have a material adverse effect on our revenues and financial condition. We are expanding into applications either through new product development projects with our existing customers or through new customer relationships, but no assurance can be given that this strategy will be successful.

In addition, customer demand for our products is subject to significant fluctuation. A prolonged economic downturn in the business or geographic areas in which we sell our products could reduce demand for our products and result in a decline in our revenue, gross margin and overall profitability. Volatility and disruption of financial and credit markets could limit our customers’ ability to obtain adequate financing to maintain operations and invest in network infrastructure and therefore could also reduce demand for our products and result in a decline in our revenue, gross margin and overall profitability. If we overestimate demand, we may experience underutilized capacity and excess inventory levels. As such, if we underestimate demand, we may miss sales opportunities and incur additional costs for labor overtime, equipment overuse and logistical complexities. Additionally, we have adverse purchase commitment liabilities pursuant to which we are contractually obligated to reimburse our contract manufacturer for the cost of excess inventory used in the manufacture of our products for which there is no forecasted or alternative use. Unexpected decreases in customer demand or our inability to accurately forecast customer demand could also result in increases in our adverse purchase commitment liability and have a material adverse effect on our gross margins and profitability.

Not all new design wins ramp into production, and even if ramped into production, the timing of such production may not occur as we or our customers had estimated or the volumes derived from such projects may not be as significant as we had estimated, which could have a substantial negative impact on our anticipated revenues and profitability.

Our product revenue growth expectations are highly dependent upon successful ramping of our design wins. The time between when we achieve a design win with a customer and when we begin shipping to that customer at production levels generally has been shortened with our standards-based model. In some cases there is no time between when a design win is achieved and when production level shipments begin. With many new design wins with our ATCA platforms and our COM Express modules, customers may require us to provide customization of our products. In addition, customers may require significant time to port their own applications to our systems. Customization of our products as well as porting of customer specific applications can take six to twelve months and in some circumstances can be as long as 24 months. After that, there is an additional time lag from the start of production ramp to peak revenue. Not all design wins ramp into production and, even if a design win ramps into production, the volumes derived from such projects may be less than we had originally estimated. Customer projects related to design wins are sometimes canceled or delayed, or can perform below original expectations, which can adversely impact anticipated revenues and profitability. In particular, the volumes and time to production ramp associated with new design wins depend on the adoption rate of new technologies in our customers’ end markets, especially in the communications networking sector. Program delays or cancellations could be more frequent during times of meaningful economic downturn or due to the consolidation of one or more of our end customers. Should technologies such as VoLTE, IMS, 3G and 4G/LTE wireless technologies, advanced multimedia applications, Femtocell applications and other emerging technologies not be adopted as fast as we or our customers anticipate, actual volumes from new design wins may be lower than we are expecting, which could adversely affect our revenue growth and gross margin expectations.

We rely on our key management and depend on the recruitment and retention of qualified personnel, and our failure to attract and retain such personnel could seriously harm our business.

A small number of key executives manage our business. Their departure could have a material adverse effect on our operations. In addition, due to the specialized nature of our business, our future performance is highly dependent upon our ability to attract and retain qualified engineering, manufacturing, marketing, sales and management personnel for our operations. Competition for personnel is intense, and we may not be successful in attracting and retaining qualified personnel.

Our failure to compete for these personnel could seriously harm our business, results of operations and financial condition. In addition, if incentive programs we offer are not considered desirable by current and prospective employees, we could have difficulty retaining or recruiting qualified personnel. If we are unable to recruit and retain key employees, our product development, marketing and sales could be harmed.

The successes of our business is dependent upon successfully managing our international operations and attracting and retaining key international employees.

In 2012 we transitioned substantially all of our remaining domestic development activities to our development centers in China and India as a part of our strategic plan to increase our engineering presence in Asia.

This strategic initiative increases our international presence, which along with our existing international operations, involve risks inherent in doing business on an international level. These risks include:


•	difficulties in managing operations due to distance, language and cultural differences;


•	different or conflicting laws and regulations;


•	accounting (including managing internal control over financial reporting in our non-U.S. subsidiaries), tax and legal complexities arising from international operations;


•	burdensome regulatory requirements and unexpected changes in these requirements, including data protection requirements;


•	political and economic instability;


•	fluctuations in currency exchange rates; and


•	different laws and regulations surrounding taxes and their potentially adverse consequences.

Our foreign currency exchange risk management program is designed to reduce, but does not eliminate, the impact of currency exchange rate movements. If we cannot manage our international operations successfully, our business, results of operations and financial condition could be adversely affected.

Acquisitions and partnerships may be more costly or less profitable than anticipated and may adversely affect the price of our common stock.

As part of our business strategy, we engage in discussions with third parties regarding, and enter into agreements relating to, acquisitions, joint ventures and divestitures in order to manage our product and technology portfolios and further our strategic objectives. We also continually look for ways to increase the profitability of our operations through restructuring efforts and to consolidate operations across facilities where synergies exist. In order to pursue this strategy successfully, we must identify suitable acquisition, alliance or divestiture candidates, complete these transactions, some of which may be large and complex, and integrate acquired companies. Integration and other risks of acquisitions can be more pronounced for larger and more complicated transactions, or if multiple acquisitions are pursued simultaneously.

The integration of acquisitions may make the completion and integration of subsequent acquisitions more difficult. However, if we fail to identify and complete these transactions, we may be required to expend resources to internally develop products and technology or may be at a competitive disadvantage or may be adversely affected by negative market perceptions, which may have a material adverse effect on our business, results of operations and financial condition.

Acquisitions may require us to integrate different company cultures, management teams and business infrastructures and otherwise manage integration risks. Even if an acquisition is successfully integrated, we may not receive the expected benefits of the transaction.

A successful sale or divestiture depends on various factors, including our ability to effectively transfer assets and liabilities, contracts, facilities and employees to the purchaser, identify and separate the intellectual property to be divested from the intellectual property that we wish to keep and reduce fixed costs previously associated with the divested assets of the business.

Managing acquisitions and divestitures requires varying levels of management resources, which may divert management's attention from our other business operations. Acquisitions, including abandoned acquisitions, also may result in significant costs and expenses and charges to earnings.

Restructuring activities may result in business disruptions and may not produce the full efficiency and cost reduction benefits anticipated. Further, the benefits may be realized later than expected and the cost of implementing these measures may

be greater than anticipated. If these measures are not successful, we may need to undertake additional cost reduction efforts, which could result in future charges. Moreover, we could experience business disruptions with customers and elsewhere if our cost reduction and restructuring efforts prove ineffective, and our ability to achieve our other strategic goals and business plans as well as our business, results of operations and financial condition could be materially adversely affected.

We operate in intensely competitive industries, and our failure to respond quickly to technological developments and incorporate new features into our products could have an adverse effect on our ability to compete.

We operate in intensely competitive industries that experience rapid technological developments, changes in industry standards, changes in customer requirements, industry migration to the private telecom cloud, and frequent new product introductions and improvements. If we are unable to respond quickly and successfully to these developments, we may lose our competitive position, and our products or technologies may become uncompetitive or obsolete. Similarly, if there are changes to technology requirements, it may render our products and technologies uncompetitive. To compete successfully, we must maintain a successful marketing and R&D effort, develop new products and production processes, and improve our existing products and processes at the same pace or ahead of our competitors. We may not be able to successfully develop and market these new products, the products we invest in and develop may not be well received by customers, and products developed and new technologies offered by others may affect the demand for our products. These types of events could have a variety of negative effects on our competitive position and our profitability and financial condition, such as reducing our revenue, increasing our costs, lowering our gross margin, reducing our profitability and/or requiring us to recognize and record impairments of our assets.

There are a number of trends and factors affecting our markets, including economic conditions in the United States, Europe and Asia, which are beyond our control. These trends and factors may result in increasing upward pressure on the costs of products and an overall reduction in demand.

There are trends and factors affecting our markets and our sources of supply that are beyond our control and may negatively affect our cost of sales. Such trends and factors include: adverse changes in the cost of raw commodities and increasing freight, energy, and labor costs in developing regions such as China and India. Our business strategy has been to provide customers with faster time-to-market and greater value solutions in order to help them compete in an industry that generally faces downward pricing pressure. In addition, our competitors have in the past lowered, and may again in the future lower, prices in order to increase their market share, which would ultimately reduce the price we may realize from our customers. If we are unable to realize prices that allow us to continue to compete on this basis of performance, our profit margin, market share, and overall financial condition and operating results may be materially and adversely affected.

Some of the products or technologies acquired, licensed or developed by us incorporate open source software, and we may incorporate open source software into other products in the future. Any failure to comply with the terms of one or more of open source licenses could negatively affect our business.

The products, services or technologies we acquire, license, provide or develop may incorporate or use open source software. We monitor our use of open source software in an effort to avoid unintended consequences, such as reciprocal license grants, patent retaliation clauses, and the requirement to license our products at no cost. Nevertheless, we may be subject to unanticipated obligations regarding our products which incorporate open source software.

Competition in the market for enabling software and systems is intense, and if we lose our market share, our revenues and profitability could decline.

We face competition in the design of enabling solutions from a number of sources. Our principal competition remains the internal design resources of our own customers. Many of our customers retain the ability to design enabling solutions in-house. In order to achieve design wins and receive subsequent orders from these customers, we must convince them of the benefits associated with using our design services and solutions rather than solutions designed by their in-house personnel. While we believe that many of our customers will increase the proportion of their solutions sourced from merchant suppliers, we will need to continue to demonstrate the benefits of our solutions relative to similar products that could be developed by our customers’ internal personnel in order to successfully execute our strategy. In addition, consolidation of our customers may cause material changes in their use of third parties to realize new product designs.

We also compete with a number of companies and divisions of companies that focus on providing enabling solutions, including, but not limited to, ADLink Technologies, Advantech Co., AudioCodes, Dialogic, Emerson Network Power, Hewlett-Packard, IBM and Kontron AG. In addition, our primary competitors in the enabling software solutions market, into which out Trillium software is sold, are Aricent Group, NodeH and Ubiquisys.

Because the enabling software and systems market is growing, the market is attracting new non-traditional competitors. These non-traditional competitors include contract manufacturers that provide design services and Asian-based original design manufacturers.

Some of our competitors and potential competitors have a number of significant advantages over us, including:


•	a longer operating history;


•	greater name recognition and marketing power;


•	preferred vendor status with our existing and potential customers;


•	significantly greater financial, technical, marketing and other resources, which allow them to respond more quickly to new or changing opportunities, technologies and customer requirements;


•	broader product and service offering to provide more complete and valued solutions; and


•	lower cost structures which, among other things, could include different accounting principles relative to U.S. generally accepted accounting principles (“GAAP”).

Furthermore, existing or potential competitors may establish cooperative relationships with each other or with third parties or adopt aggressive pricing policies to gain market share.

As a result of increased competition, we may encounter significant pricing pressures and / or suffer losses in market share. These pricing pressures could result in significantly lower average selling prices for our products. We may not be able to offset the effects of any price reductions with an increase in the number of customers, cost reductions or otherwise. In addition, many of the industries we serve, such as the communications industry, are encountering market consolidation, or are likely to encounter consolidation in the near future, which could result in increased pricing pressure and additional competition thus weakening our position or causing delays in new design wins and their associated production.

We have incurred, and may in the future incur, restructuring and other charges, the amounts of which are difficult to predict accurately.

From time to time, we have sought to optimize our operational capabilities and efficiencies and focus our efforts and expertise through business restructurings. In the future we may decide to engage in discrete restructurings of our operations if business or economic conditions warrant. Possible adverse consequences related to such actions may include various charges for such items as idle capacity, disposition costs, severance costs, loss of propriety information and in-house knowledge. We may be unsuccessful in any of our current or future efforts to restructure our business, which may have a material adverse effect upon our business, financial condition or results of operations.

Our international operations expose us to additional political, economic and regulatory risks not faced by businesses that operate only in the United States.

In 2012, 2011 and 2010, as measured by delivery destination, we derived 21%, 24% and 28% of our revenues from EMEA and 41%, 44% and 37% from Asia Pacific. In 2012, all of our manufacturing was completed by our U.S. contract manufacturer's Asian supply chain and operations. As a result, we are subject to worldwide economic and market conditions risks generally associated with global trade such as fluctuating exchange rates, tariff and trade policies, increased protectionism of foreign governments, domestic and foreign tax policies, foreign governmental regulations, political unrest, wars and other acts of terrorism and changes in other economic conditions. These risks, among others, could adversely affect the results of our operations or financial position. Additionally, some of our sales to overseas customers are made under export licenses that must be obtained from the U.S. Department of Commerce. Protectionist trade legislation in either the United States or other countries, such as a change in the current tariff structures, export compliance laws, trade restrictions resulting from war or terrorism or other trade policies could adversely affect our ability to sell or to manufacture in international markets. Additionally, U.S. federal and state agency restrictions imposed by the Buy American Act or the Trade Agreement Act may apply to our products manufactured outside the United States. Furthermore, revenues from outside the United States are subject to inherent risks, including the general economic and political conditions in each country. As a result of tightening credit markets, our customers and suppliers may face issues gaining timely access to sufficient credit, which could impair our customers’ ability to make timely payments to us and could cause key suppliers to delay shipments and face serious risks of insolvency. These risks, among others, could adversely affect our results of operations or financial position.

If we are unable to protect our intellectual property, we may lose a valuable competitive advantage or be forced to endure costly litigation.

We are a technology dependent company, and our success depends on developing and protecting our intellectual property. We rely on patents, copyrights, trademarks and trade secret laws to protect our intellectual property. At the same time, our products are complex and are often not patentable in their entirety. We also license intellectual property from third parties and rely on those parties to maintain and protect their technology. We cannot be certain that our actions will protect our proprietary rights. Any patents owned by us may be invalidated, circumvented or challenged. Any of our patent applications, whether or not being currently challenged, may not be issued with the scope of the claims we seek, if at all. If we are unable to adequately protect our technology, or if we are unable to continue to obtain or maintain licenses for protected technology from third parties, it could have a material adverse effect on our results of operations. In addition, some of our products are now designed, manufactured and sold outside of the United States. Despite the precautions we take to protect our intellectual property, this international exposure may reduce or limit protection of our intellectual property, which is more prone to design piracy outside of the United States.

Third parties may also assert infringement claims against us in the future; assertions by third parties may result in costly litigation and we may not prevail in such litigation or be able to license any valid and infringed patents from third parties on commercially reasonable terms. Litigation, regardless of its outcome, could result in substantial costs and diversion of our resources. Any infringement claim or other litigation against us or by us could materially adversely affect our financial condition and results of operations.

Our disclosure controls and internal control over financial reporting do not guarantee the absence of error or fraud.

We do not expect that disclosure controls or internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system's objectives will be met. Further, the design of a control system must reflect the fact that there are resource constraints and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. Failure of our control systems to prevent error or fraud could materially adversely impact us.

Increased IT security requirements, vulnerabilities, threats and more sophisticated and targeted computer crime could pose a risk to our systems, networks, products, solutions, services and data.

Increased global IT security requirements, vulnerabilities, threats and more sophisticated and targeted computer crime pose a risk to the security of our systems and networks and the confidentiality, availability and integrity of our data. While we attempt to mitigate these risks by employing a number of measures, including employee training, comprehensive monitoring of our networks and systems, and maintenance of backup and protective systems, our systems, networks, products, and solutions remain potentially vulnerable to advanced persistent threats. We also may have access to sensitive, confidential or personal data or information in certain of our businesses that is subject to privacy and security laws, regulations and customer-imposed controls. Despite our efforts to protect sensitive, confidential or personal data or information, our facilities and systems and those of our third-party service providers may be vulnerable to security breaches, theft, misplaced or lost data, programming and/or human errors that could potentially lead to the compromising of sensitive, confidential or personal data or information, improper use of our systems, software solutions or networks, unauthorized access, use, disclosure, modification or destruction of information, defective products, production downtimes and operational disruptions, which in turn could adversely affect our reputation, competitiveness and results of operations.

Oregon corporate law, our articles of incorporation and our bylaws contain provisions that could prevent or discourage a third party from acquiring us even if the change of control would be beneficial to our shareholders.

Our articles of incorporation and our bylaws contain anti-takeover provisions that could delay or prevent a change of control of our company, even if a change of control would be beneficial to our shareholders. These provisions:


•	authorize our Board of Directors to issue up to 5,663,952 shares of preferred stock and to determine the price, rights, preferences, privileges and restrictions, including voting rights, of those shares without prior shareholder approval, which could adversely affect the voting power or other rights of the holders of outstanding shares of preferred stock or common stock;


•	establish advance notice requirements for nominations for election to our Board of Directors or for proposing matters that can be acted upon by shareholders at shareholder meetings;


•	prohibit cumulative voting in the election of directors, which would otherwise allow less than a majority of shareholders to elect director candidates; and


•	limit the ability of shareholders to take action by written consent, thereby effectively requiring all common shareholder actions to be taken at a meeting of our common shareholders.

In addition, if our common stock is acquired in specified transactions deemed to constitute “control share acquisitions,” provisions of Oregon law condition the voting rights that would otherwise be associated with those common shares upon approval by our shareholders (excluding, among other things, the acquirer in any such transaction). Provisions of Oregon law also restrict, subject to specified exceptions, the ability of a person owning 15% or more of our common stock to enter into any “business combination transaction” with us.

The foregoing provisions of Oregon law and our articles of incorporation and bylaws could limit the price that investors might be willing to pay in the future for shares of our common stock and value of our convertible notes.

Sales of a significant number of shares of our common stock in the public markets, or the perception of such sales, could depress the market price of our common stock.

Sales of a substantial number of shares of our common stock or other equity-related securities in the public markets could depress the market price of our common stock, and impair our ability to raise capital through the sale of additional equity securities. We cannot predict the effect that future sales of our common stock or other equity-related securities would have on the market price of our common stock. As of December 31, 2012, we had $34.9 million aggregate principal amount of our 2.75% convertible senior notes due February 2013 (the "2013 convertible senior notes") and 4.50% convertible senior notes due February 2015 (the "2015 convertible senior notes") outstanding. On February 15, 2013, we paid the remaining $16.9 million principal balance of the 2013 convertible senior notes. The price of our common stock could be affected by possible sales of our common stock by investors who view convertible notes as a more attractive means of equity participation in our company and by hedging or arbitrage trading activity which we expect to occur involving our common stock.

Conversion of our convertible senior notes will dilute the ownership interest of existing shareholders, including holders who have previously converted their convertible senior notes.

Our 2015 convertible senior notes have a conversion price equivalent to $8.53 per share. Upon conversion of our 2015 convertible senior notes, some or all of the ownership interests of existing shareholders may be diluted. Any sales in the public market of our common stock issuable upon such conversion could adversely affect prevailing market prices of our common stock. In addition, the anticipated conversion of our 2015 convertible senior notes into shares of our common stock could depress the price of our common stock.

We have a substantial level of indebtedness and future obligations relative to our cash position.

As of December 31, 2012, we had $33.2 million of cash and cash equivalents which consisted of $18.7 million held domestically and $14.5 million held by foreign subsidiaries, and 2013 convertible senior notes and 2015 convertible senior notes outstanding with an aggregate principal amount of $34.9 million. In addition, we have various other short-term obligations which will require use of our cash to satisfy. This level of debt and our ability to repay or refinance this debt prior to maturity could have negative consequences to our business, including:


•	increasing the difficulty of our ability to make payments on our outstanding debt;


•	requiring a substantial portion of our cash flow from operations to be dedicated to the payment of principal and interest on our indebtedness, therefore reducing our ability to use or cash flow to fund our operations, capital expenditures, acquisitions;


•	limiting our ability to pursue our growth strategy;


•	limiting our ability to incur additional indebtedness or obtain any necessary financing in the future for working capital, capital expenditures, debt service requirements, acquisitions, or general corporate purposes;


•	placing us at a disadvantage compared to our competitors who are less highly leveraged and may be better able to use their cash flow to fund competitive responses to changing industry, market or economic conditions; and


•	increasing our vulnerability in the event of an increase in interest rates if we must incur new debt to satisfy our obligations under the 2015 convertible senior notes.

If required to fund operations, refinance debt or for other general corporate purposes, as of December 31, 2012 we have $25 million available for borrowing under our $40 million secured revolving line of credit agreement with Silicon Valley Bank,

which matures September 30, 2014. The line of credit, however, is subject to certain financial covenants and may not be available, in full or in part, on dates we may attempt to draw on the line in the future.

We may also be unable to borrow funds as a result of an inability of financial institutions to lend due to restrictive lending policies and / or institutional liquidity concerns.

If we experience a decline in revenues, we could have difficulty paying amounts due on our indebtedness. Any default under our indebtedness could have a material adverse impact on our business, operating results, and financial condition.

PART II

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Our common stock is traded on the NASDAQ Global Select Market under the symbol “RSYS.” The following table sets forth, for the periods indicated, the highest and lowest sale prices for our common stock, as reported by the NASDAQ Global Select Market.



	High		Low
2012
Fourth Quarter	$	3.76	$	2.02
Third Quarter	6.50		2.90
Second Quarter	7.49		5.65
First Quarter	8.07		5.09

Fourth Quarter	$	6.91	$	4.01
Third Quarter	8.86		5.79
Second Quarter	9.38		7.05
First Quarter	9.22		8.01

The closing price as reported on the NASDAQ Global Select Market on February 28, 2013 was $4.19 per share. As of February 28, 2013, there were approximately 530 holders of record of our common stock. We believe that the number of beneficial owners is substantially greater than the number of record holders because a large portion of our outstanding common stock is held of record in “street name” by brokers and other financial institutions for the benefit of individual investors.

Dividend Policy

We have never paid any cash dividends on our common stock and do not expect to declare cash dividends on the common stock in the foreseeable future. Our ability to pay dividends is restricted by our policy as well as the covenants arising from our line of credit agreement with Silicon Valley Bank, which prohibits the payment of any dividends, distributions or payment in respect of our common stock. As such, we plan to retain all of our earnings to finance future growth.

Share Repurchase Program

In December 2010, the Board of Directors authorized the repurchase of up to $20.0 million of our common stock through open-market transactions and privately negotiated transactions from time to time at the discretion of management. Under the program, the purchases will be funded from available working capital, and any repurchased shares will be returned to authorized but unissued status. The duration of the repurchase program was two years and ended in December 2012. Under the program, we repurchased common stock with a value of $3.9 million. The Company did not repurchase any shares of common stock during 2012.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview

We are a leader in enabling wireless infrastructure solutions for the telecom, aerospace, and defense markets. Our market-leading ATCA, market leading MRF, world-renowned Trillium software, COM Express and Network Appliance coupled with an expert professional services organization enable our customers to bring high-value products and services to telecom market faster and with lower investment and risk. These products are targeted throughout the telecommunication network from Radio Access Network ("RAN") to the Evolved Packet Core ("EPC") to the IP Mulitmedia Subsystem ("IMS"). Our MRF, an application built on ATCA platforms, provides audio conferencing, VoLTE, and video conferencing functions into the network IMS. Additionally, when these products are combined with our professional service organization of network experts we can enable our customers to bring to market solutions such as security, femto, and LTE gateways, edge routers and load balancers that are critical elements within the networks at a cost and time to market advantage when compared to internally developed solutions. Our Trillium software is the foundation for a complete turn-key application for small cells in both the 3G and LTE RAN. ATCA and Network appliance products are the platforms necessary to control and move data in the network core, as well as applications such as Deep Packet Inspection ("DPI") and policy management.

In July 2011 we acquired Continuous Computing Corporation ("Continuous Computing") a developer of communications systems consisting of highly integrated ATCA platforms and Trillium protocol software coupled with professional services to enable a full solution offering. Continuous Computing's key customer applications included 3G and 4G wireless infrastructure, Small Cell base stations, Traffic Management, Internet Offload and Network Security. The acquisition accelerated the Company's strategy to deliver more differentiated platforms and solutions.

2012 Highlights

Our business experienced challenges throughout 2012 due to an overall decline in telecom infrastructure spending, resulting in decreased volumes and downward pricing pressure specifically within our platforms products. Despite the challenging telecom market, we increased deployment of our Software-Solutions products, specifically MRF, as our customers continue to invest in upgrading audio conferencing capabilities within their networks.

During 2012 we introduced a number of key products which are expected to drive our future growth. These products included our 40G T-Series ATCA products, fully integrated platforms that decrease our customers' delivery costs while increasing performance, and our new MPX-12000 MRF which enables VoLTE capabilities for wireless carriers.

Operationally during 2012 we completed many of the planned actions undertaken in 2011 intended to reduce our overall cost structure and enable more efficient product development and product integration following our acquisition of Continuous Computing in July 2011. These actions included:


•	the consolidation to one contract manufacturer;


•	the transition of ATCA and Software-Solutions research and development teams to our offshore development centers in China and India. These transitions included the fit-out of new facilities in each location;


•	the transition and consolidation of our general and administrative supporting functions to better align with the new business structure; and


•	the downsizing of our North America facilities to smaller footprints in each location as we have transitioned certain functions to lower-cost geographies.

Following are the more significant highlights and developments within our business for the year ended December 31, 2012:

•

Revenues decreased $44.8 million to $286.1 million for the year ended December 31, 2012 from $330.9 million for the year ended December 31, 2011. The decline was caused by an expected decrease in revenue from our Other Products product group as these products continue to trend towards end of life as our largest customer transitions to ATCA platforms. This decrease was offset by increased revenue in our ATCA and Software-Solutions product groups resulting from the acquisition of Continuous Computing and increased deployments of our MRF products.

•

Our gross margin increased 1.6 percentage points in the year ended December 31, 2012 to 30.8% of revenue from 29.2% of revenue in the year ended December 31, 2011. Increased revenue in our higher margin Software-Solutions and ATCA product groups, decreased revenues from our low margin Other Products, and our continued focus on controlling manufacturing spend contributed to the increase in gross margin in 2012 as compared to 2011.


•	R&D expense increased $3.1 million to $47.7 million for the year ended December 31, 2012 from $44.6 million for the year ended December 31, 2011 as a result of additional development costs related to our 40G T-series ATCA and MPX-12000 products.

•

SG&A expense decreased $7.5 million to $45.2 million for the year ended December 31, 2012 from $52.7 million for the year ended December 31, 2011. The decrease was the result of a reduction in headcount and overhead expenses resulting from restructuring activities associated with our acquisition of Continuous Computing. Additionally, decreased sales as compared to the year ended December 31, 2011 resulted in lower commission expense.


•	During 2012, we recorded the following non-recurring charges associated with our operations:


◦	$29.7 million goodwill impairment charge resulting from a decline in the trading value of our common stock coupled with a downturn in the telecommunications market;


◦	$3.7 million in restructuring charges largely associated with the departure of certain executive officers, workforce reductions resulting from our acquisition of Continuous Computing and facility abandonments. As of December 31, 2012, these integration activities are substantially complete; and


◦	$5.1 million gain associated with the partial reversal of our contingent consideration liability resulting from the continued delay in our customers' small cell deployments.

•

Cash and cash equivalents decreased $14.6 million to $33.2 million at December 31, 2012 from $47.8 million at December 31, 2011. The decrease in cash and cash equivalents was due to the repurchase of $10.1 million of our 2013 senior convertible notes, $11.1 million in capital expenditures associated with the build out of our international facilities, continued integration-related activities associated with the acquisition of Continuous Computing and the addition of 40G ATCA test equipment. Additionally, $6.8 million of restructuring costs, primarily related to the acquisition of Continuous Computing, were paid during 2012. These cash outflows were offset by cash flows from operations, excluding payments for restructuring activities, of $12.4 million.

2013 Outlook

We are cautiously optimistic that the modestly improving market conditions experienced in the fourth quarter of 2012 will continue throughout 2013. Although overall revenue is expected to remain relatively consistent with 2012, we expect continued growth in our higher margin ATCA and Software-Solutions products as the telecom markets recover from the 2012 downturn in capital spending. Additionally, we are well positioned to capitalize on the expected recovery of telecom markets as we enter 2013 with a complete portfolio of 40G T-Series ATCA assets available for sale to our customers and have introduced our new MPX-12000 MRF product to address the increasing demand of VoLTE services.

Total revenues	$	286,096	$	330,865	$	284,311	(13.5	)%	16.4	%

ATCA

Revenues in the ATCA product group increased $4.1 million to $136.6 million in 2012 from $132.5 million in 2011. Increased revenues from the July 2011 acquisition of Continuous Computing combined with strong sales into the Japanese market more than offset the effects of a broad softening in capital spending throughout the macro telecom market. We expect continued growth in our ATCA product group as the telecom market's capital spending recovers in 2013. We continue to expect 10-15% long-term revenue growth in our ATCA product group as our recent design wins ramp to customer deployment and the introduction of our 40G T-series ATCA platforms which began shipping in the second half of 2012.

For 2011, revenues in the ATCA product group increased $46.7 million to $132.5 million in 2011 from $85.8 million in 2010. Increased revenues from our ATCA product group were due to a $25.8 million increase in revenues from increased 3G and 4G/LTE infrastructure deployments, the continued migration within our largest customer from legacy products, and a significant last-time buy of older generation ATCA products. In addition, our acquisition of Continuous Computing contributed an increase of $25.4 million over 2010 revenues.

Software-Solutions

Revenues in the Software-Solutions product group increased $15.8 million to $52.7 million in 2012 from $36.9 million in 2011. Robust demand for our MRF products, targeted at the audio conferencing market, led to increased deployments throughout our customer base when compared to 2011. Additionally, Trillium software products were added to our revenue profile in July 2011 as a result of the acquisition of Continuous Computing, and contributed to a $9.5 million increase during the first half of 2012. These increases were offset by slower than expected Trillium based small cell deployments as the adoption of small cell technology in next generation networks has been slower than we anticipated.

We expect Software-Solutions long-term revenue growth of 10-15% given an expected increase in demand for our MRF product, the ATCA-based MPX-12000. The MPX-12000 broadens the available market to include the rapidly growing VoLTE deployments as carriers seek to add voice transmission capabilities to the next generation LTE networks.

For 2011, revenues in the Software-Solutions product group increased $4.6 million to $36.9 million in 2011 from $32.3 million in 2010. This increase was attributable to the July 2011 acquisition of Continuous Computing, which contributed $8.9 million due to the addition of Trillium software products to our revenue profile. This was offset by the timing of MRF deployments.

COM Express and Rackmount Server

Revenues in the COM Express and Rackmount Server products group decreased $7.3 million to $49.5 million in 2012 from $56.8 million in 2011. Revenues decreased due to a 2010 strategic decision to de-emphasize development and sales of these products. However, in 2011, management began reinvesting in this product line, and we expect revenue growth to resume in 2013.

For 2011, revenues in the COM Express and Rackmount Server products group increased $3.7 million to $56.8 million in 2011 from $53.1 million in 2010. This was due to increased sales of our COM Express products to a customer in the telecommunications industry.

Other Products

Revenues in the Other Products product group decreased $57.2 million to $47.3 million in 2012 from $104.5 million in 2011. This decrease is the result of these hardware centric products reaching their end of life and our largest customer transitioning to ATCA-based products.

For 2011, revenues in the Other Products product group decreased $8.6 million to $104.5 million in 2011 from $113.1 million in 2010. This decrease is the result of these hardware centric products reaching end of life and our largest customer transitioning to ATCA-based products.

Revenue by Geography

The following tables outline overall revenue dollars (in thousands) and the percentage of revenues, by geographic region:



	For the Years Ended December 31,						Change
	2012		2011		2010		2012 vs 2011		2011 vs 2010
North America	$	109,168	$	107,042	$	97,361	2.0	%	9.9	%
Europe, the Middle East and Africa ("EMEA")	60,379		79,858		80,218		(24.4	)	(0.4	)
Asia Pacific	116,549		143,965		106,732		(19.0	)	34.9
Total	$	286,096	$	330,865	$	284,311	(13.5	)%	16.4	%



	For the Years Ended December 31,
	2012		2011		2010
North America	38.2	%	32.4	%	34.3	%
EMEA	21.1		24.1		28.2
Asia Pacific	40.7		43.5		37.5
Total	100.0	%	100.0	%	100.0	%

North America. North American revenues increased by $2.2 million to $109.2 million in 2012 from $107.0 million in 2011. Revenues from Software-Solutions products increased $10.5 million over 2011 resulting from our acquisition of Continuous Computing and increased deployments by our MRF customers. These increases were offset by decreased revenues from our ATCA product group of $1.8 million due to timing of deployments by our largest customers in this geography and decreased revenues from Other Products of $4.1 million as our customers transition to ATCA-based products.

North American revenues increased by $9.6 million to $107.0 million in 2011 from $97.4 million in 2010. The increase in overall North American revenues was attributable to the acquisition of Continuous Computing, which contributed $14.2 million to revenues, and an increase in revenue from our COM Express products. These increases were offset by decreased revenues from our Other Products product group.

EMEA. Revenues from the EMEA region decreased $19.5 million to $60.4 million in 2012 from $79.9 million in 2011. Revenue from our Other Products product group decreased $21.2 million as these hardware centric products are reaching their end of life.

Revenues from the EMEA region decreased $0.3 million to $79.9 million in 2011 from $80.2 million in 2010. The decrease reflects an $8.4 million decline in our Other Products revenues which was offset by a $7.0 million increase in ATCA product group revenue in 2011 from 2010. This decrease was further offset by a $3.4 million increase in revenues from our Software-Solutions product group due to the July 2011 acquisition of Continuous Computing.

Asia Pacific. Revenues from the Asia Pacific region decreased $27.5 million to $116.5 million in 2012 from $144.0 million in 2011. Softening in the macro telecom spending environment and timing of deployments within the remainder of our customer base was offset by strong deployments by our Japanese customers.

Revenues from the Asia Pacific region increased $37.3 million to $144.0 million in 2011 from $106.7 million in 2010. The increase was the result of increased revenues from our ATCA product group as a result of increased 3G and 4G/LTE infrastructure deployments. In addition, revenues in 2011 benefited from the acquisition of Continuous Computing, which contributed $12.6 million to revenues as compared to 2010.

We currently expect continued fluctuations in the percentage of revenue from each geographic region. Additionally, we expect non-U.S. revenues to remain a significant portion of our revenue profile.

Gross Margin

Gross margin as a percentage of revenues increased 1.6 percentage points to 30.8% in 2012 from 29.2% in 2011. Gross margin was favorably impacted as our higher margin ATCA and Software-Solutions products comprised 66% of our revenues in 2012 as compared to 51% during 2011. This increase in gross margin was offset by an increase in cost of sales as the amortization of purchased technology increased to $9.5 million in 2012 from $8.3 million in 2011 and a decrease in gross margin from our Other Products product group to 11% in 2012 from 22% in 2011.

Gross margin as a percentage of revenues decreased 1.5 percentage points to 29.2% in 2011 from 30.7% in 2010. Gross margin was unfavorably impacted in 2011 compared to 2010 due to the continued deterioration of gross margin for our Other Products product group and higher amortization of purchased technology, which increased to $8.3 million in 2011 from $6.2 million in 2010. These factors were offset by favorable product mix as higher margin Software-Solutions products comprised a larger share of our revenues in 2011 as compared to 2010.

Research and Development

R&D expenses consist primarily of salary, bonuses and benefits for product development staff, and cost of design and development supplies and equipment, net of reimbursements for nonrecurring engineering services. R&D expenses increased $3.1 million to $47.7 million in 2012 from $44.6 million in 2011. The increase was attributable to higher product development costs associated with the development and introduction of our 40G T-Series ATCA products and continued development of both our Trillium small cell and MPX-12000 MRF products. R&D headcount increased to 454 at December 31, 2012 from 440 at December 31, 2011.

R&D expenses increased $5.9 million to $44.6 million in 2011 from $38.7 million in 2010. These increases were due to the acquisition of Continuous Computing, which contributed $6.4 million to R&D expense in 2011 over the comparable period, an $0.8 million increase in non-recurring engineering charges and a $0.6 million increase in temporary labor. These increases were offset by lower payroll and payroll-related costs of $1.6 million in 2011 primarily resulting from the transition of R&D activities to lower cost geographies in Asia.

Selling, General, and Administrative

SG&A expenses consist primarily of salary, commissions, bonuses and benefits for sales, marketing, executive and administrative personnel, as well as professional services and costs of other general corporate activities. SG&A expenses decreased $7.5 million to $45.2 million in 2012 from $52.7 million in 2011. The decrease is the result of restructuring actions that reduced overall headcount and resulted in a decrease in payroll, commissions, and related expenses of $1.7 million in 2012 from 2011 and lower incentive compensation of $1.9 million as a result of the Company's performance. The decrease was also affected by a reduction in stock-based compensation expense of $2.7 million as a result of the reversal of expense associated with the Radisys Corporation Long-Term Incentive Plan (as amended and restated, as further amended, the "LTIP") of $1.6 million, as discussed further under stock-based compensation expense. SG&A headcount decreased to 200 at December 31, 2012 from 230 at December 31, 2011.

SG&A expenses increased $7.2 million to $52.7 million in 2011 from $45.5 million in 2010. The increase in SG&A expenses in 2011 was primarily due to the acquisition of Continuous Computing, which contributed an additional $8.1 million to SG&A expenses, increased commissions of $1.3 million resulting from strong design win performance in the second half of 2011, and increased third-party sales commissions. These increases were offset by a decrease in stock-based compensation expense of $0.6 million. Stock-based compensation expense decreased due to the reversal of LTIP expense for named executive officers that forfeited shares upon their departure as a result of not completing the requisite service period. The decrease in stock-based compensation expense was offset by increased expense for new grants and assumed options associated with acquisition of Continuous Computing.

Intangible Assets Amortization

Intangible assets amortization increased $2.3 million to $5.2 million in 2012 from $2.9 million in 2011. The increase in amortization is the result of our July 2011 acquisition of Continuous Computing. During the third quarter of 2012, we determined there were sufficient indicators of potential impairment to require an interim impairment assessment. This assessment resulted in the full impairment of our goodwill, however, during this assessment it was determined that our long-lived intangible assets were not impaired.

In 2011, intangible assets amortization increased $2.2 million to $2.9 million in 2011 from $0.7 million in 2010. Intangible assets amortization increased primarily due to the July 2011 acquisition of Continuous Computing, which contributed $2.4 million to amortization expense. The increase associated with Continuous Computing's intangible assets was offset by a decrease of $0.3 million resulting from final amortization of intangible assets associated with our 2006 acquisition of Convedia Corporation, a closely held vendor of IP media servers.

We perform reviews for impairment of the purchased intangible assets whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable.

Impairment of Goodwill

We completed an impairment analysis of goodwill pursuant to ASC 350-20-35 during the second quarter of 2012 as we determined that a triggering event occurred during the second quarter that required analysis of both our goodwill and long-lived assets for impairment. We concluded at that time that we passed the first step of the two-step impairment test and therefore no impairment of goodwill was recorded. However, during the third quarter of 2012, we observed additional impairment indicators, including a further deterioration in the market in which we operate and a decrease in our market capitalization. Accordingly, in connection with the preparation of our third quarter financial statements, we completed an interim goodwill impairment test and recorded a goodwill impairment charge of $29.7 million, representing all of our goodwill.

We estimated the fair value of our single reporting unit using a market approach. The market approach estimates fair value in part on market capitalization plus an estimated control premium paid in acquisitions of publicly traded companies with similar characteristics to Radisys. Based upon our analysis, the implied fair value of goodwill was lower than its carrying value.

Restructuring and Acquisition-Related Charges, Net

Restructuring and acquisition-related charges, net include expenses associated with restructuring activities as well as integration, transaction and legal fees, and retention bonuses incurred in connection with our acquisition of Continuous Computing. We evaluate the adequacy of the accrued restructuring charges on a quarterly basis. As a result, we record reversals to the accrued restructuring in the period in which we determine that expected restructuring and other obligations are less than the amounts accrued.

Restructuring and acquisition-related charges, net decreased $10.1 million to $(0.1) million in 2012 from $10.0 million in 2011. The $10.1 million decrease in restructuring and acquisition-related charges, net is due to activities associated with our acquisition of Continuous Computing, which were largely completed in 2011. The following is the composition of charges during 2012:


•	$1.3 million - acquisition-related charges associated with overlap of notified employees as we transition our R&D activities to lower cost geographies;


•	$1.3 million - severance and benefits provided to restructured employees. Of this charge, $0.9 million is associated with the contractual severance benefits provided to our former Chief Executive Officer;


•	$1.7 million - lease abandonment for certain North American facilities resulting from facilities rationalization;


•	$0.7 million - restructuring charges related to the Continuous Computing restructuring plan; and


•	($5.1) million - decrease in fair value of the Continuous Computing contingent consideration liability due to decreases in projected revenues earned during the applicable measurement period.

Restructuring and acquisition-related charges, net increased $8.4 million to $10.0 million in 2011 from $1.6 million in 2010. The increase is due to our acquisition of Continuous Computing, which resulted in restructuring expense of $5.1 million and acquisition-related charges of $4.9 million.

Gain on Liquidation of a Foreign Subsidiary

During 2011, as part of an update to our tax planning strategy, we completed the liquidation of Radisys Technology Ireland Limited (“RTIL”). As a result of this liquidation, we recorded a $2.1 million gain to reflect the realization of accumulated foreign currency translation adjustments related to RTIL. This gain represents the net unrealized foreign currency translation gains accumulated from changes in exchange rates and the related effects from the translation of assets and liabilities of RTIL.

Stock-based Compensation Expense

Included within costs of sales, R&D and SG&A are expenses associated with stock-based compensation. Stock-based compensation expense consists of amortization of stock-based compensation associated with unvested stock options, restricted stock units issued to employees under the 2007 stock plan, the 1998 Continuous Computing plan, the Continuous Computing inducement stock plan, LTIP, and the employee stock purchase plan (“ESPP”).

We incurred and recognized stock-based compensation expense as follows (in thousands):



	For the Years Ended December 31,						Change
	2012		2011		2010		2012 vs 2011		2011 vs 2010
Cost of sales	$	25	$	838	$	816	(97.0	)%	2.7	%
Research and development	601		1,434		1,303		(58.1	)	10.1
Selling, general and administrative	765		3,445		4,039		(77.8	)	(14.7	)
Total	$	1,391	$	5,717	$	6,158	(75.7	)%	(7.2	)%

In 2012, stock-based compensation expense decreased from 2011 due to a decrease in LTIP expense. In the second quarter of 2012, we determined it was improbable that the 2009 LTIP performance goal would be attained prior to the end of the measurement period and, as a result, previously recognized LTIP expense was reversed during the quarter ended June 30, 2012. The impact of this reversal by functional income statement classification was as follows: Cost of Sales $(0.2) million, R&D $(0.6) million, and SG&A $(1.6) million. This compares to 2011 expense recognized under the LTIP as follows: Cost of Sales $0.2 million, R&D $0.3 million, and SG&A $0.4 million.

In 2011, stock-based compensation expense decreased over 2010 due to the reversal of LTIP expense for named executive officers of $0.8 million and was offset by additional expense associated with the acquisition of Continuous Computing.

Non-Operating Expenses

The following table summarizes our non-operating expenses (in thousands):

Total	$	(1,138	)	$	(1,258	)	$	(1,553	)	(9.5	)%	(19.0	)%

Interest Expense

Interest expense includes interest incurred on our convertible notes and our lines of credit and amortization of debt issuance costs. In 2012 interest expense decreased $0.2 million to $1.7 million in 2012 from $1.9 million in 2011 due to the repurchases of $5.0 million and $10.1 million of our 2013 convertible senior notes in December 2011 and August 2012.

In 2011 interest expense decreased $0.1 million to $1.9 million from $2.0 million in 2010 due to a decrease in the outstanding balance on our revolving line of credit. During 2011, we had no outstanding balances or letters of credit outstanding on our line of credit.

Interest Income and Other Income (Expense), Net

Interest income decreased $60,000 to $39,000 in 2012 from $0.1 million in 2011 as the result of a decrease in our average cash balance resulting from our July 2011 acquisition of Continuous Computing.

Interest income decreased $0.5 million to $0.1 million in 2011 from $0.6 million in 2010 due to a decline in the weighted average balance of interest bearing investments held as a result of cash paid for the acquisition of Continuous Computing coupled with a decline in the average yield on investments due to a more conservative investment strategy.

In 2012, other income (expense), net did not materially change from 2011. We experienced an increase in the amortization of forward points expense associated with our Indian Rupee ("INR") foreign currency hedges which was offset by a decrease in the foreign exchange impact of our entities which do not use the US Dollar ("USD") as their functional currency.

In 2011, other income (expense), net increased $0.7 million to $0.5 million due to the expense of $0.2 million in 2010 as a result of the strengthening of the USD against currencies of our non-USD functional currency subsidiaries. Specifically, as a result of our acquisition of Continuous Computing, we now have exposure to the INR, which, as a result of weakening against the USD, gave rise to a substantial portion of the gain recognized in other income (expense) in 2011. In the fourth quarter of 2011, we began entering into forward foreign currency exchange contracts for the INR to limit our exposure to fluctuations in exchange rates between the INR and USD.

Income Tax Provision

We recorded tax expense of $2.6 million for the year ended December 31, 2012 as compared to a tax benefit of $11.1 million and $0.5 million for the years ended December 31, 2011 and December 31, 2010. Our current effective tax rate differs from the statutory rate primarily due to a full valuation allowance provided against our U.S. net deferred tax assets and Canadian scientific research and experimental development expenditures claims. In addition to the aforementioned items, the effective tax rate for 2011 differs from the statutory rate due to a partial release of our valuation allowance provided against its U.S. net deferred tax assets as a result of the purchase of Continuous Computing. Purchase accounting includes the establishment of a deferred tax liability due to the book tax basis differences related to specifically identified non-goodwill intangibles resulting from the acquisition. The net deferred tax liability from the acquisition created an additional source of income to utilize our deferred tax assets which resulted in a reduction of our valuation allowance. As such, due to this additional source of income an income tax benefit of $10.4 million was recognized upon the partial valuation allowance release.

At December 31, 2012 and 2011, we had net deferred tax assets of $16.5 million and $17.8 million. We had valuation allowances of $50.2 million and $46.4 million as of December 31, 2012 and 2011, which represents a full valuation allowance against our U.S. deferred tax assets. In evaluating our valuation allowance, we considered all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, and recent financial performance. Based on our review of all positive and negative evidence, including a three year U.S. cumulative pre-tax loss and taxable loss, it was concluded that a full valuation allowance should be recorded against our U.S. net deferred tax assets. In the event we were to determine that we would not be able to realize all or part of our foreign net deferred tax assets in the future, we would increase the valuation allowance and make a corresponding charge to earnings in the period in which we make such determination. Likewise, if we later determine that we are more likely than not to realize all or a portion of the U.S. net deferred tax assets, we would reverse the previously provided valuation allowance. All future reversals of the valuation allowance would result in a benefit in the period recognized. Although realization is not assured, management believes that it is more likely than not that the balance of the deferred tax assets, net of the valuation allowance, as of December 31, 2012 will be realized.

We are subject to income taxes in the U.S. and various foreign countries, and on occasion, we have been subject to corporate income tax audits. In determining the amount of income tax liabilities for uncertain tax positions, we have evaluated whether certain tax positions are more likely than not to be sustained by taxing authorities. We believe that we have adequately provided in our financial statements for additional taxes that may result from examination. To the extent the ultimate outcome of an examination differs from the amounts provided for as uncertain tax positions either additional expense or benefit will be recognized in the period in which the examination is effectively settled.

During 2011 the Canada Revenue Agency (“CRA”) completed an examination of our tax years 2006 through 2008. We agreed to the proposed adjustments and effectively settled the examination during 2011. The effective settlement did not have a significant impact on our financial statements.

During 2010 an Internal Revenue Service ("IRS") examination was effectively settled when we agreed to a Notice of Proposed Adjustment that was issued by the IRS. The Proposed Adjustment was provided in full as an uncertain tax position at December 31, 2009.

We are currently under tax examination in India. The periods covered under examination are the financial years 2004 through 2008. The examination is in various stages of appellate proceedings and all material uncertain tax positions associated with the examination have been taken into account in the ending balance of the unrecognized tax benefits at December 31, 2012.

We are not under examination by tax authorities in any other jurisdictions.

Cash Flows

Cash and cash equivalents decreased by $14.6 million to $33.2 million at December 31, 2012 from $47.8 million at December 31, 2011. As of December 31, 2012, the amount of cash held by our foreign subsidiaries was $14.5 million. During 2012, we repatriated $21.3 million with the intent of using these funds for the repayment of our February 2013 convertible senior notes in the amount of $17.5 million of principal and accrued interest and for continued use in our U.S. operations. It is no longer our intent to permanently reinvest funds in certain of our foreign entities and we expect to continue to repatriate cash from these foreign entities on an ongoing basis in future periods. Repatriation of funds from these foreign entities is not expected to result in actual cash tax payments due to the utilization of previously generated operating losses and credits of our U.S. entity.

Operating Activities

Cash provided by operating activities in 2012 was $5.6 million and consisted of a net loss of $43.5 million, adjustments for non-cash items of $57.9 million and decrease in working capital items of $8.8 million. For the year ended December 31, 2012 primary drivers to changes in our working capital consisted of the following:


•	Net trade accounts receivable increased as the result of the timing of our shipments and customer payments.


•	Inventories decreased due to the sale of previously built buffer stock and end of life products associated with our consolidation of contract manufacturing providers and the decrease of MRF stock held resulting from an increase in shipment activity.


•	Accounts payable increased as a direct result of our timing of vendor payments.


•	Deferred income decreased as a result of the timing of customer billings not recognized as revenues due to undelivered elements or acceptance provisions contained in certain arrangements.


•	Other accrued liabilities decreased as a result of timing of payments. Specifically, accrued wages and bonuses decreased due to a decrease in our variable compensation provision for 2012 as compared to 2011. Accrued restructuring decreased as a result of payments in 2012 associated with 2011 activities. Finally, the contingent

consideration liability resulting from our acquisition of Continuous Computing decreased due to a decline in projected revenues earned during the arrangement.

Cash provided by operating activities in 2011 was $14.8 million and consisted of a net loss of $1.5 million, adjustments for non-cash items of $14.2 million and cash provided by working capital and other activities of $2.1 million. For the year ended December 31, 2011 primary drivers to changes in our working capital, net of changes attributable to the acquisition of Continuous Computing, consisted of the following:


•	Net trade accounts receivable increased primarily as the result of increased revenues, the timing of our shipments, and customer payments.


•	Inventories increased significantly due to the build-up of buffer stock and end of life products as we finalized our transition to one contract manufacturer.


•	Accounts payable increased as a direct result of our build in inventories as well as timing of vendor payments.


•	Deferred income increased as a result of the timing of customer billings not recognized as revenues due to undelivered elements or acceptance provisions contained in certain arrangements.

Investing Activities

Cash used in investing activities in 2012 of $11.2 million was attributable to $11.1 million used for capital expenditures related to integration activities, including the build out of our new facilities in Shenzhen, China and Bangalore, India, as well as purchases of development and test equipment associated with our introduction of 40G T-Series ATCA products.

Cash used in investing activities in 2011 of $88.0 million was attributable to $79.3 million used for the acquisition of Continuous Computing and capital expenditures of $8.2 million related to integration activities, including the build out of our new facility in Bangalore, India, as well as the transition to one contract manufacturer.

Financing Activities

Cash used in financing activities in 2012 of $9.0 million was the result of our repurchase of $10.1 million aggregate principal amount of our 2013 convertible senior notes, which was offset by cash received for net payments related to stock-based award activities of $1.3 million.

Cash used in financing activities in 2011 of $8.1 million was the result of our repurchase of $5.0 million aggregate principal amount of our 2013 convertible senior notes for $4.9 million and repurchases of our common stock of $3.9 million under our share repurchase program. These outflows were offset by cash received for net payments related to stock-based award activities of $1.6 million.

As of December 31, 2012 and December 31, 2011, working capital was $41.9 million and $71.2 million. The decrease in our working capital from December 31, 2011 is due to the reclassification of our 2013 convertible senior notes, with a balance of $16.9 million aggregate principal amount, from long-term to short-term debt during 2012 and $11.1 million in capital expenditures.

Line of Credit

Silicon Valley Bank

We have a $40.0 million secured revolving line of credit agreement (as amended, the “Agreement”) with Silicon Valley Bank (“SVB”) maturing on September 30, 2014. On October 29, 2012, the Agreement was amended to revise the minimum two quarter rolling EBITDA financial covenant and the calculation of the Availability Amount (as defined in the Agreement) such that all permitted borrowings under the Agreement are subject to the borrowing base formula in the Agreement. In addition, the amendment modified the frequency of liquidity testing from quarterly to monthly. The secured revolving credit facility is available for cash borrowings and subject to a borrowing formula based upon eligible accounts receivable. Eligible accounts receivable (as defined in the Agreement) include 80% of US and 65% of foreign accounts receivable for our U.S. companies, limited to concentration by certain customers, not greater than 60 days past due and no greater than 120 days from original invoice date. Borrowings under the Agreement bear interest at the prime rate, which was 3.25% as of December 31, 2012, or LIBOR, which was 0.21% as of December 31, 2012, plus 1.25%, with either interest rate determined by our election. We are required to make interest payments monthly. We are further required to pay a commitment fee equal to $35,000 on the closing date of the Agreement and annually thereafter and to pay quarterly in arrears an unused facility fee in an amount equal to 0.375% per year of the unused amount of the facility.

The Agreement requires us to make and maintain certain financial covenants, representations, warranties and other agreements that are customary in credit agreements of this type. The Agreement also requires us to maintain the following specific financial covenants:

•

minimum monthly liquidity ratio of 1.25 during the term of the Agreement. The liquidity ratio is defined as cash, cash equivalents and short term investments (with cash and cash equivalents held by our foreign subsidiaries not to exceed $10.0 million and excluding any investments held by our foreign subsidiaries) plus eligible accounts receivable (as defined in the Agreement), divided by the sum of obligations owing to SVB under the Agreement;

•

minimum two quarter positive rolling EBITDA (earnings before interest, taxes, depreciation, amortization, stock based compensation, goodwill impairment charges, and non-cash restructuring and integration expenses associated with the acquisition of Continuous Computing) of $3.0 million beginning with the quarter ending June 30, 2013. Prior to June 30, 2013, the minimum two quarter rolling EBITDA requirements increase on a quarterly basis with the quarter ending December 31, 2012 as follows: ($3.5) million, and ($1.0) million; and


•	capital expenditures may not exceed $20.0 million during the period January 1, 2011 to December 31, 2012 and $8.0 million in subsequent years.

As of December 31, 2012, we had no outstanding balances or letters of credit issued on our behalf under the Agreement. At December 31, 2012, based on the amended agreement, we had $25.1 million of available capacity under the Agreement. We expect to draw upon the line of credit in 2013 as needed to fund our U.S. operations after the repayment of our 2013 notes due February 15, 2013. As of December 31, 2012, we were in compliance with all covenants.

2013 Convertible Senior Notes

During February 2008, we offered and sold in a public offering pursuant to a shelf registration statement $55.0 million aggregate principal amount of 2.75% convertible senior notes due February 2013 (the “2013 convertible senior notes”).

During the fourth quarter of 2011, we repurchased $5.0 million aggregate principal amount of the 2013 convertible senior notes, with associated unamortized issuance costs of $81,000. We repurchased the notes in the open market for $4.9 million and recorded a net gain of $44,000.

During 2012, we exchanged, in a private offering, $18.0 million aggregate principal amount of the 2013 convertible senior notes, for $18.0 million aggregate principal amount of 4.50% convertible senior notes due February 2015 (the “2015 convertible senior notes”). We accounted for the exchange in accordance with the relevant accounting guidance for debt exchanges and modifications. Refer below for further details of the 2015 convertible senior notes.

During 2012, we repurchased $10.1 million aggregate principal amount of the 2013 convertible senior notes with associated unamortized issuance costs of $58,000. We repurchased the notes in the open market for $10.1 million and recorded a net gain of $17,000. These repurchases reduced the outstanding 2013 senior convertible notes at December 31, 2012 to $16.9 million.

As of December 31, 2012 and 2011, we had outstanding 2013 convertible senior notes with a face value of $16.9 million and $45.0 million of which $16.9 million and $0 were classified as current liabilities on the Consolidated Balance Sheets. As of December 31, 2012 and 2011, the fair value of our 2013 convertible senior notes was $16.6 million and $41.8 million.

On February 15, 2013, the maturity date of the 2013 convertible senior notes, we repaid the entire outstanding balance of the 2013 convertible senior notes in accordance with the terms thereof.

2015 Convertible Senior Notes

On June 20, 2012, we entered into subscription agreements with certain holders of the 2013 convertible senior notes. Pursuant to the subscription agreements, on June 29, 2012 we exchanged $18.0 million aggregate principal amount of the 2013 convertible senior notes for $18.0 million aggregate principal amount of the new 2015 convertible senior notes. The 2015 convertible senior notes mature on February 15, 2015. Holders of the 2015 convertible senior notes may convert their notes into a number of shares of our common stock determined as set forth in the indenture governing the notes at their option on any day to and including the business day prior to the maturity date. The 2015 convertible senior notes are initially convertible into 117.2333 shares of our common stock per $1,000 principal amount of the notes (which is equivalent to a conversion price of approximately $8.53 per share), subject to adjustment upon the occurrence of certain events. Upon the occurrence of a

fundamental change, holders of the 2015 convertible senior notes may require us to repurchase some or all of their notes for cash at a price equal to 100% of the principal amount of the notes being repurchased, plus accrued and unpaid interest, if any. In addition, if certain fundamental changes occur, we may be required in certain circumstances to increase the conversion rate for any 2015 convertible senior notes converted in connection with such fundamental changes by a specified number of shares of our common stock. The 2015 convertible senior notes are general unsecured obligations and rank equal in right of payment to all of our existing and future senior indebtedness, and senior in right of payment to our future subordinated debt. Our obligations under the 2015 convertible senior notes are not guaranteed by, and are effectively subordinated in right of payment to all existing and future obligations of its subsidiaries and are effectively subordinated in right of payment to its future secured indebtedness to the extent of the assets securing such debt.

As of December 31, 2012 we had outstanding 2015 convertible senior notes with a face value of $18.0 million. As of December 31, 2012, the fair value of our 2015 convertible senior notes was $17.7 million, which is based on quoted prices of our publicly traded debt on such balance sheet date.

Derivatives

We enter into forward foreign currency exchange contracts for the Indian Rupee to reduce the impact of foreign currency exchange risks where natural hedging strategies could not be effectively employed.

We do not hold or issue derivative financial instruments for trading purposes. The purpose of our hedging activities is to reduce the risk that the eventual cash flows of the underlying assets, liabilities and firm commitments will be adversely affected by changes in exchange rates. In general, our hedging activities do not create foreign currency exchange rate risk because fluctuations in the value of the instruments used for hedging purposes are offset by fluctuations in the value of the underlying exposures being hedged. Counterparties to derivative financial instruments expose us to credit-related losses in the event of non-performance. We do not believe there is a significant credit risk associated with our hedging activities because the counterparties are all large financial institutions with high credit ratings.

All derivatives, including foreign currency exchange contracts are recognized on the balance sheet at fair value. Unrealized gain positions are recorded as other current assets and unrealized loss positions are recorded as other current liabilities. Changes in the fair values of the outstanding derivatives that are highly effective are recorded in other comprehensive income (loss) until net income (loss) is affected by the variability of the cash flows of the hedged transaction. Typically, hedge ineffectiveness could result when the amount of our hedge contracts exceed our forecasted or actual transactions for which the hedge contracts were designed to hedge. Once a hedge contract matures the associated gain (loss) on the contract will remain in other comprehensive income until the underlying hedged transaction affects net income (loss), at which time the gain (loss) will be recorded to the expense line item being hedged, which is primarily Cost of Sales and R&D. One of the criteria for this accounting treatment is that the forward foreign currency exchange contract amount should not be in excess of specifically identified anticipated transactions. By their nature, estimates of anticipated transactions may fluctuate over time and may ultimately vary from actual transactions. If anticipated transaction estimates or actual transaction amounts decrease below hedged levels, or when the timing of transactions change significantly, we would reclassify a portion of the cumulative changes in fair values of the related hedge contracts from other comprehensive income (loss) to other income (expense) during the quarter in which the changes occur.

Contractual Obligations

The following summarizes our contractual obligations at December 31, 2012 and the effect of such on our liquidity and cash flows in future periods (in thousands):



	Total		2013		2014-2015		2016-2017		2018 & Thereafter
Operating leases	$	11,932	$	3,007	$	5,318	$	2,341	$	1,266

Total	$	67,334	$	37,464	$	26,263	$	2,341	$	1,266



(A)	Purchase obligations include agreements or purchase orders to purchase goods or services that are enforceable and legally binding and specify all significant terms, including: fixed or minimum quantities to be purchased, fixed, minimum or variable price provisions and the approximate timing of the transaction. Purchase obligations exclude agreements that are cancelable without penalty. These purchase obligations are entered into in the ordinary course of business and are expected to be funded by cash flows from continuing operations.

(B)	Contingent consideration reflects the earn-out payments we agreed to pay in connection with the acquisition of Continuous Computing. The amounts are based on forecasted revenues at December 31, 2012 and will change based on the actual revenues at each payout date. See Note 4 - Acquisitions of the Notes to the Consolidated Financial Statements for additional information regarding the contingent consideration.

(C)	The 2013 convertible senior notes were repaid in full on February 15, 2013.

In addition to the above, we have approximately $2.9 million associated with unrecognized tax benefits. We are not able to reasonably estimate when we would make any cash payments required to settle these liabilities, but do not believe that the ultimate settlement of our obligations will materially affect our liquidity.

Off-Balance Sheet Arrangements

We do not engage in any activity involving special purpose entities or off-balance sheet financing.

Shelf Registration Statement

On October 26, 2010, we filed an unallocated shelf registration statement on Form S-3 for the offering from time to time of up to $100 million in securities consisting of common stock, preferred stock, depositary shares, warrants, debt securities or units consisting of one or more of these securities. The SEC declared the shelf registration statement effective on November 24, 2010, and it will expire in November 2013. Except as may be stated in a prospectus supplement for any particular offering, we intend to use the net proceeds from the sale of any securities for general corporate purposes, which may include acquiring companies in our industry and related businesses, repaying existing debt, providing additional working capital and procuring capital assets.

Liquidity Outlook

At December 31, 2012, our cash and cash equivalents amounted to $33.2 million. We believe our current cash and cash equivalents, cash expected to be generated from operations and our line of credit facility will satisfy our short and long-term expected working capital needs, capital expenditures, acquisitions, stock repurchases, and other liquidity requirements associated with our existing business operations. As a result of our repayment of our 2013 convertible senior notes on February 15, 2013, we expect to utilize our line of credit to supplement our cash balances in order to address inter-quarter timing of cash collections and payments. We believe our current working capital, plus availability under the line of credit, provides sufficient liquidity to operate the business at normal levels throughout 2013.

Critical Accounting Policies and Estimates

Management’s discussion and analysis of our financial condition and results of operations is based upon the Consolidated Financial Statements, which have been prepared in accordance with U.S. GAAP. The preparation of these financial statements requires management to make estimates and judgments that may affect the reported amounts of assets, liabilities, and revenues and expenses. On an on-going basis, management evaluates its estimates. Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

An accounting policy is deemed to be critical if it requires an accounting estimate to be made based on assumptions about matters that are highly uncertain at the time the estimate is made, and if different estimates that reasonably could have been used, or changes in the accounting estimates that are reasonably likely to occur periodically, could materially impact the financial statements. Management believes the following critical accounting policies reflect the more significant estimates and assumptions used in the preparation of the Consolidated Financial Statements.

Revenue Recognition

Multiple Element Arrangements

A significant portion of our revenue relates to product sales for which revenue is recognized upon shipment, with limited judgment required related to product returns. Most product sales are shipped FOB shipping point. The software elements included in certain components of ATCA systems and MRF products are considered to be functioning together with the non-software elements to provide the tangible product's essential functionality and these arrangements generally include multiple elements such as hardware, technical support services as well as software upgrades or enhancements on a when and if available basis. Arrangements that include multiple elements require significant management judgment to evaluate the effective terms of agreements, our performance commitments and determination of fair value of the various deliverables under the arrangement.

ASU 2009−13 provides a fair value hierarchy in order to determine the appropriate relative fair value for each element of an arrangement. When available, we use vendor specific objective evidence (“VSOE”) to determine the estimated selling price. In the absence of VSOE or third−party evidence ("TPE") for a delivered element, we then use an estimated selling price in order to determine fair value. Estimated selling prices represent our best estimate of the price at which it would transact if the deliverables were sold on a standalone basis. For technical support services, we generally determine our selling price based on VSOE as supported by substantive renewal rates in the related service agreements. In certain instances where VSOE cannot be established, we then rely upon the estimated selling price for such deliverables as TPE is generally not available due to the unique company specific terms surrounding such service agreements. In establishing an appropriate estimated selling price for these technical support agreements, we considered entity specific factors such as its historical and projected costs, historical and projected revenues, and profit objectives. We also considered market specific factors when establishing reasonable profit objectives.

Revenues on a product and services basis are as follows (in thousands):



	For the Years Ended December 31,
	2012		2011		2010
Hardware	$	235,870	$	300,505	$	257,533
Software licenses and royalties	23,162		13,952		16,614
Technical support services	14,295		6,635		4,980
Professional and other services	12,769		9,773		5,184
Total revenues	$	286,096	$	330,865	$	284,311

Hardware

Revenue from hardware products is recognized in accordance with ASC 605 Revenue Recognition. Under our standard terms and conditions of sale, we transfer title and risk of loss to the customer at the time product is shipped to the customer and revenue is recognized accordingly, unless customer acceptance is uncertain or significant obligations remain. We reduce revenue for estimated customer returns for rotation rights as well as for price protection rights according to agreements with our distributors. The amount of revenues derived from these distributors as a percentage of total revenues was 16.0%, 24.3% and 18.1% for the years ended December 31, 2012, 2011 and 2010, respectively. We accrue the estimated cost of product warranties based on historical experience at the time we recognize revenue.

The software elements included in certain components of ATCA systems and MRF products are considered to be functioning together with the non-software elements to provide the tangible product's essential functionality and our ATCA arrangements generally include multiple elements such as hardware, technical support services as well as specified software upgrades or enhancements.

Software licenses and royalties

Revenue from software licenses and royalties is recognized in accordance with ASC 985 Software. Revenue from customers for prepaid, non-refundable software royalties is recorded when the revenue recognition criteria have been met. Revenue for non-prepaid royalties is recognized at the time the underlying product is shipped by the customer paying the royalty. We recognize software license revenue at the time of shipment or upon delivery of the software master provided that the revenue recognition criteria have been met and VSOE exists to allocate the total fee to all undelivered elements of the arrangement. We defer revenue on arrangements including specified software upgrades until the specified upgrade has been delivered.

Technical support services

Technical support services are recognized as earned on the straight-line basis over the terms of the contract in accordance with applicable GAAP for revenue recognition. The fair value of our post-contract support has been determined by renewal rates within our support agreements, the actual amounts charged to customers for renewal of their support services or based on an estimated selling price.

Professional and other services

Professional services revenue is recognized upon completion of certain contractual milestones and customer acceptance of the services rendered. Other services revenues include hardware repair services and custom software implementation projects. Hardware repair services revenues are recognized when the services are complete. Software implementation revenues are recognized upon completion of certain contractual milestones and customer acceptance of the services rendered or as services are performed under the percentage-of-completion method when we are reasonably able to estimate the total effort required to complete the contract.

Deferred income

Deferred income represents amounts received or billed for the following types of transactions:


•	Undelivered elements of an arrangement—Certain arrangements include specified software upgrades and enhancements to an existing product. Revenue for such arrangements is deferred until the future obligation is fulfilled.


•	Technical support services—We have a number of technical support agreements with our customers for hardware and software maintenance. Generally, these services are billed in advance and recognized over the term of the agreement.

•

Distributor sales—Certain sales are made to distributors under agreements providing price protection and right of return on unsold merchandise. Revenue and costs relating to such distributor sales are deferred until the product is sold by the distributor or return privileges and price protection rights terminate, at which time related estimated distributor resale revenue, estimated effects of distributor price adjustments, and estimated costs are reflected in the Consolidated Statements of Operations. As of December 31, 2012 we no longer have material deferred revenues associated with distributor sales as a result of revising the terms of our agreements during 2012.

Allowance for Doubtful Accounts

We have a relatively small set of multinational customers that typically make up the majority of our accounts receivable balance. Our allowance for doubtful accounts is determined using a combination of factors to ensure that our trade receivables balances are not overstated. We record reserves for individual accounts when we become aware of a customer’s inability to meet its financial obligations to us, such as in the case of bankruptcy filings or deterioration in the customer’s operating results or financial position. If circumstances related to customers change, our estimates of the recoverability of receivables would be further adjusted. At December 31, 2012, 24.7% of our accounts receivable was due from our largest customer. If one of our large customers or a number of our smaller customers files for bankruptcy or otherwise is unable to pay the amounts due to us, the current allowance for doubtful accounts may not be adequate. During the years ended December 31, 2012 and 2011, there were no significant account balances reserved.

We maintain a non-specific bad debt reserve for all customers. This non-specific bad debt reserve is calculated based on our historical pattern of bad debt write offs as a percentage of annual revenues, which percentage is then applied to the current rolling four-quarter's revenue.

Inventory Valuation

We record an inventory valuation allowance for estimated obsolete or unmarketable inventories as the difference between the cost of inventories and the estimated net realizable value based upon assumptions about future demand and market conditions. Our inventory valuation allowances establish a new cost basis for inventory. Factors influencing the provision include: changes in demand; rapid technological changes; product life cycle and development plans; component cost trends; product pricing; regulatory requirements affecting components; and physical deterioration. If actual market conditions are less favorable than those projected by management, additional provisions for inventory reserves may be required. Our estimate for the allowance is based on the assumption that our customers comply with their current contractual obligations. We provide long-life support to our customers and therefore we have material levels of customer specific inventory. If our customers experience a financial hardship or if we experience unplanned cancellations of customer contracts, the current provision for the inventory reserves may be inadequate. Additionally, we may incur additional expenses associated with any non-cancelable purchase obligations to our suppliers if they provide customer-specific components.

Goodwill and Long-Lived Assets

Our long-lived assets include definite-lived intangible assets and property and equipment. The net balance of our definite-lived intangible assets and property and equipment at December 31, 2012 amounted to $70.3 million and $17.7 million.

Intangible assets, net of accumulated amortization, primarily consist of acquired patents, completed technology, technology licenses, trade names and customer lists. Intangible assets are being amortized on a straight-line basis over estimated useful lives ranging from six months to ten years. Property and equipment, net of accumulated depreciation, primarily consists of office equipment and software, manufacturing equipment, leasehold improvements and other physical assets owned by us. Property and equipment are being depreciated or amortized on a straight-line basis over estimated useful lives ranging from one to fifteen years. We assess impairment of intangible assets and property and equipment whenever conditions indicate that the carrying values of the assets may not be recoverable.

Conditions that would trigger a long-lived asset impairment assessment include, but are not limited to, a significant adverse change in legal factors or in the business climate that could affect the value of an asset or an adverse action or assessment by a regulator. If we determine that a long-lived asset impairment assessment is required, we must determine the fair value of the asset. Impairments would be recognized in operating results to the extent that the carrying value exceeds this calculated fair value of the long-lived assets.

Considerable management judgment is required in determining if and when a condition would trigger an impairment assessment of our long-lived assets and once such a determination has been made, considerable management judgment is required to determine the expected future cash flows and the fair market value of the long-lived asset. If the trading price or the

average trading price of our common stock is below the book value per share for a sustained period or if and when a condition has triggered an impairment analysis of our long-lived assets, we may incur substantial impairment losses due to the write-down or the write-off of our long-lived assets.

Goodwill represents the excess of cost over the assigned value of the net assets in connection with all acquisitions. Goodwill is reviewed for impairment during the fourth quarter as well as when certain triggering events suggest impairment has occurred. As of December 31, 2012 and 2011, the Company's balance of goodwill was $0 and $29.7 million.

Accrued Restructuring

Because we have a history of paying severance benefits, expenses associated with exit or disposal activities are recognized when probable and estimable.

We have engaged, and may continue to engage, in restructuring actions, which require us to make significant estimates in several areas including: realizable values of assets made redundant or obsolete; expenses for severance and other employee separation costs; the ability and timing to generate sublease income, as well as our ability to terminate lease obligations at the amounts we have estimated; and other exit costs. Should the actual amounts differ from our estimates, the amount of the restructuring charges could be materially impacted. For a description of our restructuring actions, refer to our discussion of restructuring and acquisition-related charges, net in the Results of Operations section.

Accrued Warranty

We provide for the estimated cost of product warranties at the time revenue is recognized. Our standard product warranty terms generally include repairs or replacement of a product at no additional charge for a specified period of time, which is generally 12 or 24 months after shipment. The workmanship of our products produced by our contract manufacturer is covered under warranties provided by the contract manufacturer for 12 months. We engage in extensive product quality programs and processes, including actively monitoring and evaluating the quality of our component suppliers. Our estimated warranty obligation is based upon ongoing product failure rates, internal repair costs, contract manufacturing repair charges for repairs not covered by the contract manufacturer’s warranty, average cost per call and current period product shipments. If actual product failure rates, repair rates, service delivery costs, or post-sales support costs differ from our estimates, revisions to the estimated warranty liability would be required. Additionally, we accrue warranty costs for specific customer product repairs that are in excess of our warranty obligation calculation described above. Accrued warranty reserves are included in short-term and long-term other accrued liabilities in the accompanying Consolidated Balance Sheets.

Income Taxes

Income tax accounting requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and tax bases of the assets and liabilities. We record a valuation allowance to reduce deferred tax assets if it is “more likely than not” that all or a portion of the asset will not be realized due to inability to generate sufficient taxable income in the relevant period to utilize the deferred tax asset. Our net deferred tax assets amounted to $16.5 million as of December 31, 2012. We have considered future market growth, forecasted earnings, future taxable income, the mix of earnings in the jurisdictions in which we operate and prudent and feasible tax planning strategies in determining the need for a valuation allowance. In the event we were to determine that we would not be able to realize all or part of our net deferred tax assets in the future, we would increase the valuation allowance and make a corresponding charge to earnings in the period in which we make such determination. Likewise, if we later determine that we are more likely than not to realize the net deferred tax assets, we would reverse the applicable portion of the previously provided valuation allowance. All future reversals of the valuation allowance would result in a benefit in the period recognized.

We evaluate liabilities for estimated tax exposures in all of our operational jurisdictions. The calculation of our tax liabilities includes addressing uncertainties in the application of complex tax regulations. We recognize liabilities for uncertain tax positions in the U.S. and other tax jurisdictions based on recognition and measurement criteria that allow financial statement benefits to be recognized only for tax positions that are more-likely-than-not to be sustained upon tax audit, administrative appeals or final court determination. The liabilities are reviewed for their adequacy and appropriateness. Changes to our assumptions could cause a revision of past estimates. Such a change in measurement would result in the recognition of a tax benefit or an additional charge to the tax provision.

Stock-based Compensation

We measure stock-based compensation at the grant date, based on the fair value of the award, and recognize expense on a straight-line basis over the employee's requisite service period. For LTIP and Overlay (certain performance-based restricted stock unit awards under the overlay plan of the 2007 Stock Plan, the "Overlay") awards the requisite service period is equal to the period of time over which performance objectives underlying the award are expected to be achieved. The number of LTIP and Overlay shares that vest depends on the achievement of certain performance criteria over the measurement period. Quarterly, we reevaluate the period during which the performance objective will be met and the number of LTIP and Overlay shares expected to vest. The amount of expense recorded each period for LTIP and Overlay awards is based on our estimate of the number of awards that will ultimately vest.

We estimate the fair value of stock options and purchase rights under our employee stock purchase plans using a Black-Scholes option-pricing model. The Black-Scholes option-pricing model incorporates several highly subjective assumptions including expected volatility, expected term and interest rates.

In reaching our determination of expected volatility, we use the historic volatility of our shares of common stock. We base the expected term of our stock options on historic experience. The expected term for purchase rights under our employee stock plans is based on the 18 month offering period. The risk-free rate is based on the U.S. Treasury constant maturities in effect at the time of grant for the expected term of the option or share.

The calculation includes several assumptions that require management's judgment. The expected term of the option or share is determined based on assumptions about patterns of employee exercises and represents a probability-weighted average time-period from grant until exercise of stock options, subject to information available at time of grant. Determining expected volatility generally begins with calculating historical volatility for a similar long-term period and then considers the ways in which the future is reasonably expected to differ from the past.

The input factors used in the valuation model are based on subjective future expectations combined with management judgment. If there is a difference between the assumptions used in determining stock-based compensation cost and the actual factors which become known over time, we may change the input factors used in determining stock-based compensation costs. These changes may materially impact the results of operations in the event such changes are made. In addition, if we were to modify any awards, additional charges would be taken. If our actual forfeiture rate is materially different from our estimate the stock-based compensation expense could be significantly different from what we have recorded in the current period. See Note 18-Employee Benefit Plans of the Notes to the Consolidated Financial Statements for a further discussion on stock-based compensation.

Contingent Consideration

Contingent consideration is recorded at the acquisition date based upon the estimated fair value of the contingent payment for all acquisitions. The fair value of the contingent consideration is remeasured each reporting period with any adjustments in fair value included in our Consolidated Statements of Operations.

Recent Accounting Pronouncements

In July 2012, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2012-02, “Intangibles - Goodwill and Other: Testing Indefinite-Lived Intangible Assets for Impairment,” which permits an entity to make a qualitative assessment to determine whether it is more likely than not that an indefinite-lived intangible asset, other than goodwill, is impaired. Entities are required to test indefinite-lived intangible assets for impairment at least annually and more frequently if indicators of impairment exist. If an entity concludes, based on an evaluation of all relevant qualitative factors, that it is not more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount, it is not required to perform the quantitative impairment test for that asset. Because the qualitative assessment is optional, an entity is permitted to bypass it for any indefinite-lived intangible asset in any period and apply the quantitative test. ASU 2012-02 also permits the entity to resume performing the qualitative assessment in any subsequent period. ASU 2012-02 is effective for impairment tests performed for fiscal years beginning after September 15, 2012 and early adoption is permitted. We do not expect the adoption of ASU 2012-02 to have any impact on our financial position, results of operations or cash flows.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

We are exposed to market risk from changes in interest rates, foreign currency exchange rates, and equity trading prices, which could affect our financial position and results of operations.

Foreign Currency Risk. We pay the expenses of our international operations in local currencies, namely, the Canadian Dollar, Euro, Chinese Yuan, Indian Rupee, Japanese Yen, Malaysian Ringgit, New Shekel and British Pound Sterling. Our international operations are subject to risks typical of an international business, including, but not limited to: differing economic conditions, changes in political climate, differing tax structures, foreign exchange rate volatility and other regulations and restrictions. Accordingly, future results could be materially and adversely affected by changes in these or other factors. We are also exposed to foreign exchange rate fluctuations as the balance sheets and income statements of our foreign subsidiaries are translated into U.S. Dollars during the consolidation process. Because exchange rates vary, these results, when translated, may vary from expectations and adversely affect overall expected profitability.

Based on our policy, we have established a foreign currency exposure management program which uses derivative foreign exchange contracts to address nonfunctional currency exposures. In order to reduce the potentially adverse effects of foreign currency exchange rate fluctuations, we have entered into forward exchange contracts. These hedging transactions limit our exposure to changes in the U.S. Dollar to the Indian Rupee exchange rates, and as of December 31, 2012 the total notional or contractual value of the contracts we held was $14.0 million. These contracts will mature over the next two years.

Holding other variables constant, a 10% adverse fluctuation, in relation to our hedge positions, of the U.S. Dollar relative to the Indian Rupee would require an adjustment of $1.4 million and increase our Indian Rupee hedge liability as of December 31, 2012, to $1.7 million. A 10% favorable fluctuation, in relation to our hedge positions, of the U.S. Dollar relative to the Indian Rupee would result in an adjustment of $1.4 million, reversing our Indian Rupee hedge liability and creating a hedge asset as December 31, 2012, in the amount of $1.1 million. We do not expect a 10% fluctuation to have any impact on our operating results as the underlying hedged transactions will move in an equal and opposite direction. If there is an unfavorable movement in the Indian Rupee relative to our hedged positions this would be offset by reduced expenses, after conversion to the U.S. Dollar, associated with obligations paid for in the Indian Rupee.

Convertible Notes. The fair value of the 2013 and 2015 convertible senior notes is sensitive to interest rate changes as well as changes in our stock price. Interest rate changes would result in an increase or decrease in the fair value of the convertible senior notes due to differences between market interest rates and rates in effect at the inception of the obligation. Fluctuations in our stock price would result in an increase or decrease in the fair value of the convertible senior notes due to the value of the notes derived from the conversion feature. Unless we elect to repurchase our convertible senior notes in the open market, changes in the fair value of the convertible senior notes have no impact on our cash flows or Consolidated Financial Statements. The estimated combined fair value of the 2013 and 2015 convertible senior notes was $34.3 million at December 31, 2012.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. The Company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding reliability of financial reporting and the preparation and fair presentation of published financial statements for external purposes in accordance with generally accepted accounting principles.

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.

Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2012. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control—Integrated Framework. Based on our assessment, we conclude that, as of December 31, 2012 the Company’s internal control over financial reporting is effective based on those criteria 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.

The effectiveness of internal control over financial reporting as of December 31, 2012, has been audited by KPMG, LLP, the independent registered public accounting firm who also audited the Company’s Consolidated Financial Statements included in this Item 8, as stated in the report which appears on page 47 hereof.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders

Radisys Corporation:

We have audited the accompanying consolidated balance sheets of Radisys Corporation and subsidiaries as of December 31, 2012 and 2011, and the related consolidated statements of operations, comprehensive loss, changes in shareholders' equity, and cash flows for each of the years in the three-year period ended December 31, 2012. We also have audited Radisys Corporation's internal control over financial reporting as of December 31, 2012, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Radisys Corporation's management is responsible for these consolidated financial statements, 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 these consolidated financial statements and an opinion on the Company's internal control over financial reporting 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 audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting 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 audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

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.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Radisys Corporation and subsidiaries as of December 31, 2012 and 2011, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2012, in conformity with U.S. generally accepted accounting principles. Also in our opinion, Radisys Corporation maintained, in all material respects, effective internal control over financial reporting as of December 31, 2012, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Note 1 — Nature of Operations

Radisys is a leader in enabling wireless infrastructure solutions for the telecom, aerospace, and defense markets. The Company's market-leading ATCA, MRF, COM Express, Network Appliance and world-renowned Trillium software coupled with an expert professional services organization enable the Company's customers to bring high-value products and services to telecom market faster and with lower investment and risk. These products are targeted throughout the telecommunication network from Radio Access Network ("RAN") to the Evolved Packet Core ("EPC") to the IP Mulitmedia Subsystem ("IMS"). Trillium software is the foundation for a complete turn-key application for small cells in both the 3G and LTE RAN. ATCA and Network Appliance products are the platforms necessary to control and move data in the network core, as well as applications such as Deep Packet Inspection ("DPI") and policy management. The Company's MRF, an application built on ATCA platforms, provides audio conferencing, VoLTE, and video conferencing functions into the network IMS. Additionally, when these products are combined with the Company's professional service organization of network experts they can enable customers to bring to market solutions such as security, femto, and LTE gateways, edge routers and load balancers that are critical elements within the networks at a cost and time to market advantage when compared to internally developed solutions.

Note 2 — Significant Accounting Policies

Principles of Consolidation

The accompanying Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries. All inter-company accounts and transactions have been properly eliminated in consolidation.

Management Estimates

The Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). The preparation of these Consolidated Financial Statements requires management to make estimates and judgments that may affect the amounts reported in its Consolidated Financial Statements and accompanying notes. Actual results may differ from these estimates under different assumptions or conditions.

Revenue Recognition

Multiple Element Arrangements

A significant portion of the Company's revenue relates to product sales for which revenue is recognized upon shipment, with limited judgment required related to product returns. Most product sales are shipped FOB shipping point. The software elements included in certain components of ATCA systems and MRF products are considered to be functioning together with the non-software elements to provide the tangible product's essential functionality and these arrangements generally include multiple elements such as hardware, technical support services as well as software upgrades or enhancements on a when and if available basis. Arrangements that include multiple elements require significant management judgment to evaluate the effective terms of agreements, the Company's performance commitments and determination of fair value of the various deliverables under the arrangement.

For hardware sales which may include software, ASU 2009−13 provides a fair value hierarchy in order to determine the appropriate relative fair value for each element of an arrangement. When available, the Company uses vendor specific objective evidence (“VSOE”) to determine the estimated fair value of each element of the arrangement. In the absence of VSOE or third−party evidence ("TPE") for a delivered element, the Company then uses an estimated selling price in order to determine fair value. Estimated selling prices represent the Company's best estimate of the price at which it would transact if the deliverables were sold on a standalone basis. For technical support services, the Company generally determines its selling price based on VSOE as supported by substantive renewal rates in the related service agreements. In certain instances where VSOE cannot be established, the Company then relies upon its estimated selling price for such deliverables as TPE is generally not available due to the unique company-specific terms surrounding such service agreements. In establishing an appropriate estimated selling price for these technical support agreements, the Company considered entity specific factors such as its historical and projected costs, historical and projected revenues, and profit objectives. The Company also considered market specific factors when establishing reasonable profit objectives.

Hardware

Revenue from hardware products is recognized in accordance with Accounting Standard Codification ("ASC") 605 Revenue Recognition. Under the Company’s standard terms and conditions of sale, the Company transfers title and risk of loss to the customer at the time product is shipped to the customer and revenue is recognized accordingly, unless customer acceptance is uncertain or significant obligations remain. The amount of revenues derived from distributors as a percentage of revenues was 16.0%, 24.3% and 18.1% for the years ended December 31, 2012, 2011 and 2010. Revenues associated with distributors are generally recognized upon shipment as the Company has established a sell-to model with distributors. The Company accrues the estimated cost of product warranties, based on historical experience at the time the Company recognizes revenue.

The software elements included in certain components of ATCA systems and MRF products are considered to be functioning together with the non-software elements to provide the tangible product's essential functionality and the Company’s ATCA arrangements generally include multiple elements such as hardware, technical support services as well as specified software upgrades or enhancements. As such, the revenue associated with these products is recognized in accordance with applicable GAAP for revenue recognition.

Software licenses and royalties

Revenue from software licenses and royalties is recognized in accordance with ASC 985 Software. Revenue from customers for prepaid, non-refundable software royalties is recorded when the revenue recognition criteria have been met. Revenue for non-prepaid royalties is recognized at the time the underlying product is shipped by the customer paying the royalty. The Company recognizes software license revenue at the time of shipment or upon delivery of the software master provided that the revenue recognition criteria have been met and VSOE exists to allocate the total fee to all undelivered elements of the arrangement. The Company defers revenue on arrangements, including specified software upgrades, until the specified upgrade has been delivered.

Technical support services

Technical support services are recognized as earned on the straight-line basis over the terms of the contract. The fair value of the Company’s post-contract support has been determined by renewal rates within the Company’s support agreements, the actual amounts charged to customers for renewal of their support services or based on an estimated selling price.

Professional and other services

Professional services revenue is recognized upon completion of certain contractual milestones and customer acceptance of the services rendered. Other services revenues include hardware repair services and custom software implementation projects. Hardware repair services revenues are recognized when the services are complete. Software implementation revenues are recognized upon completion of certain contractual milestones and customer acceptance of the services rendered or as services are performed under the percentage-of-completion method when the Company is reasonably able to estimate the total effort required to complete the contract.

Deferred income

Deferred income represents amounts received or billed for the following types of transactions:


•	Undelivered elements of an arrangement—Certain software sales include specified upgrades and enhancements to an existing product. Revenue for such products is deferred until the future obligation is fulfilled.


•	Technical support services—The Company has a number of technical support agreements with customers for hardware and software maintenance. Generally, these services are billed in advance and recognized over the term of the agreement.

•

deferred revenues associated with distributor sales as a result of revising the terms of the related agreements during 2012.

Capitalized Software Development Costs

The Company does not capitalize internal software development costs incurred in the production of computer software as the Company does not incur any material costs between the point of technological feasibility and general release of the product to customers in the future. As such software development costs are expensed as research and development (“R&D”) costs.

Shipping Costs

The Company’s shipping and handling costs for product sales are included under cost of sales for all periods presented. For the years ended December 31, 2012, 2011 and 2010 shipping and handling costs represented approximately 1% of cost of sales.

Advertising Costs

The Company expenses advertising costs as incurred. Advertising costs consist primarily of media, display, web, and print advertising, along with trade show costs and product demos and brochures. For the years ended December 31, 2012, 2011 and 2010 advertising costs were $2.1 million, $2.2 million and $2.1 million.

Cash Equivalents

The Company considers all highly liquid investments purchased with an original or remaining maturity of three months or less at the date of purchase to be cash equivalents.

Accounts Receivable

Trade accounts receivable are stated net of an allowance for doubtful accounts. An allowance for doubtful accounts is maintained for estimated losses resulting from the inability of customers to make required payments. Management reviews the allowance for doubtful accounts quarterly for reasonableness and adequacy. If the financial condition of the Company’s customers were to deteriorate resulting in an impairment of their ability to make payments, additional provisions for uncollectible accounts receivable may be required. In the event the Company determined that a smaller or larger reserve was appropriate, it would record a credit or a charge in the period in which such determination is made. In addition to specific customer reserves, the Company maintains a non-specific bad debt reserve for all customers. This non-specific bad debt reserve is calculated based on the Company's historical pattern of bad debt write offs as a percentage of annual revenues, which percentage is then applied to the current rolling four-quarters revenue. The Company’s customers are concentrated in the technology industry and the collection of its accounts receivable are directly associated with the operational results of the industry.

Inventories

Inventories are stated at the lower of cost, determined on the first-in, first-out (FIFO) basis, or market, net of an inventory valuation allowance. The Company uses a standard cost methodology to determine the cost basis for its inventories. The Company evaluates inventory on a quarterly basis for obsolete or slow-moving items to ascertain if the recorded allowance is reasonable and adequate. Inventory is written down for estimated obsolescence or unmarketable inventory equal to the difference between the cost of inventory and the estimated net realizable value based upon assumptions about future demand and market conditions. The Company's inventory valuation allowances establish a new cost basis for inventory.

Goodwill and Long-Lived Assets

Long-lived assets, such as property and equipment and definite-life intangible assets are evaluated for impairment whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable. The Company assesses the impairment of the assets based on the undiscounted future cash flow the assets are expected to generate compared to the carrying value of the assets. If the carrying amount of the assets is determined not to be recoverable, a write-down to fair value is recorded. Management estimates future cash flows using assumptions about expected future operating performance. Management’s estimates of future cash flows may differ from actual cash flow due to, among other things, technological changes, economic conditions or changes to the Company’s business operations.

Intangible assets with estimable useful lives are amortized on a straight-line basis over their respective estimated life and reviewed for impairment whenever events or circumstances require management to do so. In connection with the impairment of goodwill recorded during the third quarter of 2012, the long-lived assets were analyzed for impairment and it was concluded that there was no impairment.

Property and Equipment

Property and equipment is recorded at historical cost and generally depreciated or amortized on a straight-line basis according to the table below. In certain circumstances where the Company is aware that an asset’s life differs from the general guidelines set forth in its policy, management adjusts its depreciable life accordingly, to ensure expense is being recognized over the appropriate future periods. Ordinary maintenance and repair expenses are expensed when incurred.



Machinery, equipment, furniture and fixtures		5 years

The Company leases all of its facilities, certain office equipment and vehicles under non-cancelable operating leases that expire at various dates through 2020, along with options that permit renewals for additional periods. Rent escalations are considered in the determination of straight-line rent expense for operating leases. Leasehold improvements made at the inception of or during the lease are amortized over the shorter of the asset life or the lease term.

Accrued Restructuring and Other Charges

Expenses associated with exit or disposal activities are recognized when probable and estimable because the Company has a history of paying severance benefits. For leased facilities that were no longer used, an amount equal to the total future lease obligations from the date of vacating the premises through the expiration of the lease, net of projected future sublease income, is recorded as a component of restructuring charges.

Warranty

The Company provides for the estimated cost of product warranties at the time it recognizes revenue. Products are generally sold with warranty coverage for a period of 12 or 24 months after shipment. On a quarterly basis the Company assesses the reasonableness and adequacy of the warranty liability and adjusts such amounts as necessary. Warranty reserves are included in other accrued liabilities and other long-term liabilities in the accompanying Consolidated Balance Sheets as of December 31, 2012 and 2011.

Research and Development

Research, development and engineering costs are expensed as incurred. R&D expenses consist primarily of salary, bonuses and benefits for product development staff, and cost of design and development supplies and equipment, net of reimbursements for non-recurring engineering services.

Income Taxes

Income tax accounting requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial statement carrying amounts and tax bases of assets and liabilities. Valuation allowances are established to reduce deferred tax assets if it is “more likely than not” that all or portion of the asset will not be realized due to inability to generate sufficient taxable income in the relevant period to utilize the deferred tax asset. Tax law and rate changes are reflected in the period such changes are enacted. The Company recognizes uncertain tax positions

after evaluating whether certain tax positions are more likely than not to be sustained by taxing authorities. In addition, the Company recognizes potential accrued interest and penalties related to unrecognized tax benefits in income tax expense.

Fair Value of Financial Assets and Liabilities

The Company measures at fair value certain financial assets and liabilities, including cash equivalents, short-term investments, contingent consideration, and the cash surrender value of life insurance contracts. GAAP specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs have created the following fair-value hierarchy:

Level 1—Quoted prices for identical instruments in active markets;

Level 2—Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and

Level 3—Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

Comprehensive Income (Loss)

The Company reports accumulated other comprehensive income (loss) in its Consolidated Balance Sheets. Comprehensive income (loss) includes net income (loss), translation adjustments and unrealized gains (losses) on hedging instruments. The cumulative translation adjustments consist of unrealized gains (losses) for foreign currency translation.

Stock-Based Compensation

The Company measures stock-based compensation at the grant date, based on the fair value of the award, and recognize expense on a straight-line basis over the employee's requisite service period. For LTIP and Overlay awards the requisite service period is equal to the period of time over which performance objectives underlying the award are expected to be achieved. The number of LTIP and Overlay shares that vest depends on the achievement of certain performance criteria over the measurement period. Quarterly, the Company reevaluates the probability that the performance objectives will be met and the number of LTIP and Overlay shares expected to vest. The amount of expense recorded each period for LTIP and Overlay awards is based on the Company's estimate of the number of awards that will ultimately vest.

Net income (loss) per share

Basic earnings per share amounts are computed based on the weighted-average number of common shares outstanding. Diluted earnings per share incorporates the incremental shares issuable upon the assumed exercise of stock options, incremental shares associated with the assumed vesting of restricted stock and the assumed conversion of the Company’s convertible notes, as if the conversion to common shares had occurred at the beginning of the fiscal year and when such conversion would have a dilutive effect. When the conversion of the Company’s convertible notes are dilutive, earnings have been adjusted for interest expense incurred on the convertible notes.

Derivatives

The Company hedges exposure to changes in exchange rates from the US Dollar to both the Indian Rupee and Canadian Dollar. These derivatives are recognized on the balance sheet at their fair value. Unrealized gain positions are recorded as other current assets and unrealized loss positions are recorded as other accrued liabilities. Changes in the fair values of the outstanding derivatives that are highly effective are recorded in other comprehensive income until net income (loss) is affected by the variability of the cash flows of the hedged transaction. Typically, hedge ineffectiveness could result when the amount of the Company’s hedge contracts exceed the Company’s forecasted or actual transactions for which the hedge contracts were designed to hedge. Once a hedge contract matures the associated gain (loss) on the contract will remain in other comprehensive income until the underlying hedged transaction affects net income (loss), at which time the gain (loss) will be recorded to the expense line item being hedged, which is primarily cost of sales and R&D. The Company only enters into derivative contracts in order to hedge foreign currency exposure. If the Company entered into a contract for speculative reasons or if the Company’s current hedge position becomes ineffective, changes in the fair values of the derivatives would be recognized in earnings in the current period.

Foreign currency translation

Assets and liabilities of international operations, using a functional currency other than the U.S. dollar, are translated into U.S. dollars at exchange rates as of December 31, 2012 and 2011. Income and expense accounts are translated into U.S. dollars at the average daily rates of exchange prevailing during the period. Adjustments resulting from translating foreign functional currency financial statements into U.S. dollars are recorded as a separate component in shareholders’ equity. Foreign exchange transaction gains and losses are included in other income (expense), net, in the Consolidated Statements of Operations.

Contingent Consideration

Recent Accounting Pronouncements

In July 2012, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2012-02, “Intangibles - Goodwill and Other: Testing Indefinite-Lived Intangible Assets for Impairment,” which permits an entity to make a qualitative assessment to determine whether it is more likely than not that an indefinite-lived intangible asset, other than goodwill, is impaired. Entities are required to test indefinite-lived intangible assets for impairment at least annually and more frequently if indicators of impairment exist. If an entity concludes, based on an evaluation of all relevant qualitative factors, that it is not more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount, it is not required to perform the quantitative impairment test for that asset. Because the qualitative assessment is optional, an entity is permitted to bypass it for any indefinite-lived intangible asset in any period and apply the quantitative test. ASU 2012-02 also permits the entity to resume performing the qualitative assessment in any subsequent period. ASU 2012-02 is effective for impairment tests performed for fiscal years beginning after September 15, 2012 and early adoption is permitted. The Company does not expect the adoption of ASU 2012-02 to have any impact on the Company's financial position, results of operations or cash flows.

Note 3 — Goodwill

The Company reviews goodwill for impairment annually at the beginning of its fourth fiscal quarter and whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable. Conditions that would trigger an impairment assessment, include, but are not limited to, a significant adverse change in legal factors or in the business climate that could affect the value of an asset or an adverse action. The Company is considered one reporting unit.

The goodwill impairment test involves a two-step process. The first step compares the fair value of the reporting unit to its carrying value. If the fair value of the reporting unit exceeds its carrying value, goodwill is not impaired and no further testing is required. If the fair value of the reporting unit is less than the carrying value, the second step of the impairment test is to measure the amount of impairment loss. In the second step, the reporting unit's fair value is allocated to all of the assets and liabilities of the reporting unit, including any unrecognized intangible assets, in a hypothetical analysis that calculates the implied fair value of goodwill in the same manner as if the reporting unit was being acquired in a business combination. If the implied fair value of the reporting unit's goodwill is less than the carrying value, the difference is recorded as an impairment loss.

During the third quarter of 2012, the Company determined that sufficient indicators of potential impairment existed to require an interim goodwill impairment assessment. These indicators included the recent trading value of the Company's common stock, coupled with overall telecommunications market conditions. As a result, the Company compared its book value to its market capitalization, adjusted for factors such as a control premium and concluded step two of the impairment test should be performed.

The Company estimated the fair value of its single reporting unit using a market approach. The market approach estimates fair value in part on market capitalization plus an estimated control premium paid in acquisitions of publicly traded companies with similar characteristics to the Company. Based on the Company's analysis, the implied fair value of goodwill was lower than its carrying value. As a result, the Company recorded a full impairment charge of $29.7 million against the carrying amount of goodwill and as of December 31, 2012 the Company had no goodwill. The impairment charge is included in Impairment of goodwill in the Consolidated Statements of Operations.

Note 4 — Acquisitions

Acquisition of Continuous Computing

On July 8, 2011, the Company acquired 100% of the outstanding shares of Continuous Computing Corporation ("Continuous Computing"), a developer of communications systems consisting of highly integrated ATCA platforms and Trillium protocol software. The Company expects the acquisition to accelerate the Company's strategy to deliver more differentiated platforms and solutions. Continuous Computing also brings expansion into high growth markets with many new customers, creating meaningful customer diversification.

Under the terms of the acquisition agreement, the Company paid approximately $81.5 million in cash and 2,321,016 in shares of the Company's common stock. The aggregate cash amount consisted of $73.0 million plus an $8.5 million working capital adjustment. The Company also deposited an additional 1,344,444 shares of its common stock into an escrow account and subject to any indemnification claims, one-half of the shares held therein were released one year after the closing of the acquisition with the remainder to be released six months thereafter. During 2012, the Company released one-half of the escrow shares as expected. The common stock issued to former shareholders of Continuous Computing had a fair value of $30.8 million, based on the closing price of the Company's common stock on July 8, 2011 of $8.39 per share.

In addition, the Company has agreed to make certain earn-out payments based on the amount of product royalty revenues generated by a specified set of contracts associated with certain of Continuous Computing's products over a period of 36 months after closing. Earn-out payments will be made in cash in three installments following the 18, 24 and 36-month anniversaries of the closing date, and in each case will equal the amount of such royalty revenues during the immediately preceding 18-month, six-month or 12-month period, as applicable, except that, in lieu of making any and all earn-out payments, the Company may elect at any time prior to the fifth business day following the 18-month anniversary of the closing date to make a one-time payment in cash and/or issuance of common stock with a combined aggregate value of $15 million. The estimated fair value of this contingent consideration at December 31, 2012 was $2.5 million of which $0.8 million is included in other accrued liabilities and $1.7 million is included in other long-term liabilities in the Consolidated Balance Sheet. See Note 5 - Fair Value of Financial Instruments for additional information regarding the valuation of the contingent consideration liability.

In connection with the acquisition, the Company assumed Continuous Computing's stock incentive plan as to stock options held by continuing employees of Continuous Computing that were not vested on or prior to June 30, 2011, which were converted into options to acquire approximately 319,000 shares of the Company's common stock. See Note 18 - Employee Benefit Plans for additional information regarding the valuation of the assumed options.

The total acquisition consideration is as follows (in thousands):



Cash paid for initial consideration	$	73,009
Working capital adjustment	8,504
Fair value of contingent consideration (earn-out payments)	7,400
Share consideration payable upon closing:
3.7 million Radisys common shares	30,753
Fair value of stock options	65
Total preliminary purchase price	$	119,731

Purchase Price Allocation

The purchase price in excess of the fair value of the tangible and identified intangible assets acquired less liabilities assumed is recognized as goodwill. During the year ended December 31, 2012, the Company revised the purchase price allocation for the acquisition of Continuous Computing as a result of final measurement period adjustments. This revision is the result of finalizing the accounting for certain tax matters, which was completed during the three months ended March 31, 2012. These adjustments resulted in an additional release of the Company's valuation allowance provided against its U.S. net deferred tax assets, which resulted in additional deferred tax benefit reported in third-quarter 2011 financial information of approximately $2.7 million. As required by ASC 805-10, the Company's statements of operations and cash flows for the period ending December 31, 2011, as well as the balance sheet at December 31, 2011, have been revised to reflect the impact of these measurement period adjustments. The Company filed a Form 8-K on September 10, 2012 to provide revised consolidated financial statements as of and for the year ended December 31, 2011.

The final allocation of the total purchase price is as follows (in thousands):



Total preliminary purchase price				$	119,731
Fair value of net tangible assets acquired and liabilities assumed:
Cash and cash equivalents	$	2,214
Accounts receivable	13,434
Inventories	4,036
Prepaid expenses and other current assets	3,316
Fixed assets	2,469
Other assets	614
Accounts payable	(5,368		)
Accrued expenses	(6,891		)
Deferred revenue	(1,825		)
Other long-term liabilities	(1,226		)
				10,773
Fair value of identifiable intangible assets acquired				89,240
Net deferred tax liability				(9,870		)
Goodwill				$	29,588

The goodwill created by the transaction of $29.6 million is not deductible for tax purposes. Key factors that make up the goodwill created by the transaction include expected synergies from the combination of operations and the knowledge and experience of the acquired workforce and infrastructure.

The Company is amortizing purchased technology and backlog to amortization of purchased technology in the Consolidated Statements of Operations over the respective estimated life of each intangible asset. Customer relationships and trade name are being amortized to intangible assets amortization in the Consolidated Statements of Operations over the respective estimated life of each intangible asset.

Note 5 — Fair Value of Financial Instruments

The Company measures at fair value certain financial assets and liabilities. GAAP specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company's market assumptions. These two types of inputs have created the following fair-value hierarchy:

Level 1— Quoted prices for identical instruments in active markets;

Level 2— Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and

Level 3— Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

Foreign currency forward contracts are measured at fair value using models based on observable market inputs such as foreign currency exchange rates; therefore, they are classified within Level 2 of the valuation hierarchy. The cash surrender value of life insurance contracts is measured at fair value using quoted market prices for similar instruments; therefore, they are classified within Level 2 of the valuation hierarchy.

The Company has obligations ("contingent consideration"), to be paid in cash, related to the acquisition of Continuous Computing based on the amount of product royalty revenues to be generated by a specified set of contracts associated with certain of Continuous Computing's products over a period of 36 months after closing. The contingent consideration liability was established at the time of acquisition and is evaluated at the end of each reporting period. As the significant inputs used in determining the fair value are unobservable, this liability is classified within Level 3 of the fair value hierarchy.

The fair value of this contingent consideration is determined by calculating the net present value of the expected payments using significant inputs that are not observable in the market, including revenue projections and discount rates consistent with the level of risk of achievement; therefore the Company developed its own assumptions for the expected product royalty revenues generated under the arrangement. The fair value of the contingent consideration is affected most significantly by changes in the amount and timing of the revenue projections. If the revenue projections increase or decrease, the fair value of the contingent consideration will adjust accordingly in amounts that will vary based on the timing of the projected revenues and expected payments.

The following table summarizes the fair value measurements as of December 31, 2012 for the Company's financial instruments (in thousands):



	Fair Value Measurements as of December 31, 2012

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

As discussed in Note 3 - Goodwill, during the third quarter of 2012, the Company performed an interim goodwill impairment assessment which resulted in a full impairment of the Company's goodwill, resulting in an impairment charge of $29.7 million. In the evaluation of goodwill, the Company used a market-based approach to estimate the fair value of its single reporting unit by adding to the Company's recent stock price a control premium that a hypothetical buyer would pay over the market price to acquire a majority share of the Company. The fair value of the single reporting unit was used to calculate an implied fair value of goodwill, which was compared to the carrying amount to measure the amount of impairment loss that should be recorded. The Company believes this is the most reliable indicator of fair value and is consistent with the approach a market place participant would use. This approach is categorized as a level 3 fair value measurement technique. The estimation of fair value utilizing the above approach includes numerous uncertainties which require significant judgment when making assumptions of the control premium, expected growth rates and the selection of discount rates, as well as assumptions regarding general economic and business conditions, among other factors.

Based on the analysis described above, the Company determined the fair value of its single reporting unit to be $130.2 million, using a control premium of 47%. Key assumptions used in measuring the fair value of the Company's projected intangible assets included a discount rate of 18%, revenue growth for the Company's technologies, including expected future attrition rates, and estimated royalty rates ranging 8% to 20% (based on the respective technology) used in the relief-from-royalty method to value the Company's technology assets.

The Company also assessed long-lived assets for impairment during the third quarter of 2012, comparing the undiscounted future cash flow the assets are expected to generate to the carrying value of the assets. The probability-weighted analysis of expected undiscounted future cash flows exceeded the book value of the long lived assets by $22.0 million, or 23%. Key assumptions used in this analysis included revenue growth for the Company's technologies as well as general economic and business conditions.

(A)	The Company is contractually obligated to reimburse its contract manufacturer for the cost of excess inventory that has been purchased as a result of the Company's forecasted demand when there is no alternative use. The Company's inventory deposit represents a cash deposit paid to its contract manufacturer for inventory in excess of near term demand. The deposit is recorded net of adverse purchase commitment liabilities, and therefore the net balance of the deposit represents inventory the Company believes will be utilized. The deposit will be applied against future adverse purchase commitments owed to the Company's contract manufacturers or reduced based on the usage of inventory. See Note 15 - Commitments and Contingencies for additional information regarding the Company's adverse purchase commitment liability.

Consigned inventory is held at third-party locations, including the Company's contract manufacturing partner and customers. The Company retains title to the inventory until purchased by the third-party. Consigned inventory, consisting of raw materials and finished goods, was $0.7 million and $3.8 million at December 31, 2012 and 2011.

The Company recorded the following charges associated with the valuation of inventory, inventory deposit and the adverse purchase commitment liability for the years ended December 31 (in thousands):

The Company records certain reclassifications between categories and reversals to the accrued restructuring charges based on the results of the evaluation. The total accrued restructuring charges for each restructuring event are not affected by reclassifications. Reversals are recorded in the period in which the Company determines that expected restructuring obligations are less than the amounts accrued.

2009 Restructurings

During 2012, all remaining activities related to the 2009 plan were completed resulting in $63 thousand cash expenditures.

Fourth Quarter 2010 Restructuring

During 2012, all remaining activities related to the 2010 plan were completed resulting in $16 thousand net reversals and $202 thousand cash expenditures.

Continuous Computing Related Restructuring

During the second quarter of 2011, the Company initiated a restructuring plan associated with the acquisition of Continuous Computing. The plan included the identification of 117 positions at various locations that will be eliminated. In addition, these integration activities align with the Company's corporate objective to transfer a significant portion of its research and development activities to offshore lower cost geographies. Life to date, the Company recorded restructuring costs, net of reversals, of $5.9 million which consisted of severance, healthcare benefits, related payroll costs and legal fees. The Company expects activity associated with the restructuring plan to be substantially completed by the second quarter of 2013.

Note 12 — Short-Term Borrowings

Silicon Valley Bank

The Company has a $40.0 million secured revolving line of credit agreement (as amended, the “Agreement”) with Silicon Valley Bank (“SVB”) maturing on September 30, 2014. On October 29, 2012, the Agreement was amended to revise the minimum two quarter rolling EBITDA financial covenant and the calculation of the Availability Amount (as defined in the Agreement) such that all permitted borrowings under the Agreement are subject to the borrowing base formula in the Agreement. In addition, the amendment modified the frequency of liquidity testing from quarterly to monthly, all as more particularly described below. The secured revolving credit facility is available for cash borrowings and subject to a borrowing formula based upon eligible accounts receivable. Eligible accounts receivable (as defined in the Agreement) include 80% of US and 65% of foreign accounts receivable for the Company's U.S. companies, limited to concentration by certain customers, not greater than 60 days past due and no greater than 120 days from original invoice date. Borrowings under the Agreement bear interest at the prime rate, which was 3.25% as of December 31, 2012, or LIBOR, which was 0.21% as of December 31, 2012, plus 1.25%, with either interest rate determined by the Company's election. The Company is required to make interest payments monthly. The Company is further required to pay a commitment fee equal to $35,000 on the closing date of the Agreement and annually thereafter and to pay quarterly in arrears an unused facility fee in an amount equal to 0.375% per year of the unused amount of the facility.

The Agreement requires the Company to make and maintain certain financial covenants, representations, warranties and other agreements that are customary in credit agreements of this type. The Agreement also requires the Company to maintain the following specific financial covenants:

•

minimum quarterly liquidity ratio of 1.25 during the term of the Agreement. The liquidity ratio is defined as cash, cash equivalents and short term investments (with cash and cash equivalents held by the Company's foreign subsidiaries not to exceed $10.0 million and excluding any investments held by the Company's foreign subsidiaries) plus eligible accounts receivable (as defined in the Agreement), divided by the sum of obligations owing to SVB under the Agreement;

•


•	capital expenditures may not exceed $20.0 million during the period January 1, 2011 to December 31, 2012 and $8.0 million in subsequent years.

As of December 31, 2012 and 2011, the Company had no outstanding balances or letters of credit issued on its behalf under the Agreement that existed on those dates. At December 31, 2012, the Company had $25.1 million of available capacity under the Agreement and was in compliance with all covenants.

Note 13 — Convertible Debt

2013 Convertible Senior Notes

During February 2008, the Company offered and sold in a public offering pursuant to the shelf registration statement $55.0 million aggregate principal amount of 2.75% convertible senior notes due 2013 (the “2013 convertible senior notes”).

During the year ended December 31, 2012, the Company exchanged, in a private offering, $18.0 million aggregate principal amount of the 2013 convertible senior notes for $18.0 million aggregate principal amount of 4.50% convertible senior notes due 2015 (the “2015 convertible senior notes”). The Company accounted for the exchange in accordance with the relevant accounting guidance for debt exchanges and modifications. Refer below for further details of the 2015 convertible senior notes.

During the year ended December 31, 2012, the Company repurchased $10.1 million aggregate principal amount of the 2013 convertible senior notes, decreasing the aggregate principal amount of the 2013 senior convertible notes outstanding at December 31, 2012 to $16.9 million.

On February 15, 2013, the maturity date of the 2013 convertible senior notes, the Company repaid the entire outstanding aggregate principal balance of $16.9 million in accordance with the terms thereof.

2015 Convertible Senior Notes

On June 20, 2012, the Company entered into subscription agreements with certain holders of the Company's 2013 convertible senior notes. Pursuant to the subscription agreements, on June 29, 2012 the Company exchanged $18.0 million aggregate principal amount of the 2013 convertible senior notes for $18.0 million aggregate principal amount of the Company's 2015 convertible senior notes. The 2015 convertible senior notes mature on February 15, 2015. Holders of the 2015 convertible senior notes may convert their notes into a number of shares of the Company's common stock determined as set forth in the indenture governing the notes at their option on any day to and including the business day prior to the maturity date. The 2015 convertible senior notes are initially convertible into 117.2333 shares of the Company's common stock per $1,000 principal amount of the notes (which is equivalent to a conversion price of approximately $8.53 per share), subject to adjustment upon the occurrence of certain events. Upon the occurrence of a fundamental change, holders of the 2015 convertible senior notes may require the Company to repurchase some or all of their notes for cash at a price equal to 100% of the principal amount of the notes being repurchased, plus accrued and unpaid interest, if any. In addition, if certain fundamental changes occur, the Company may be required in certain circumstances to increase the conversion rate for any 2015 convertible senior notes converted in connection with such fundamental changes by a specified number of shares of the Company's common stock. The 2015 convertible senior notes are the Company's general unsecured obligations and rank equal in right of payment to all of its existing and future senior indebtedness, and senior in right of payment to the Company's future subordinated debt. The Company's obligations under the 2015 convertible senior notes are not guaranteed by, and are effectively subordinated in right of payment to all existing and future obligations of its subsidiaries and are effectively subordinated in right of payment to its future secured indebtedness to the extent of the assets securing such debt.

As of December 31, 2012 and December 31, 2011, the Company had outstanding 2013 and 2015 convertible senior notes with a combined face value of $34.9 million and $45.0 million, respectively. Of these balances $16.9 million and $0 were classified as current liabilities in the Condensed Consolidated Balance Sheets at December 31, 2012 and December 31, 2011. As of December 31, 2012 and December 31, 2011, the fair value of the Company's 2013 and 2015 convertible senior notes were $34.3 million and $41.8 million, which is based on quoted prices of the Company's publicly traded debt on each balance sheet date.

As described above, on February 15, 2013 the Company repaid the outstanding aggregate principal balance of $16.9 million in accordance with the terms thereof.

Note 14 — Hedging

The Company’s business activities expose it to a variety of market risks, including the effects of changes in foreign currency exchange rates. The Company manages these risks through the use of forward exchange contracts, designated as foreign-currency cash flow hedges, in an attempt to reduce the potentially adverse effects of foreign currency exchange rate fluctuations that occur in the normal course of business. As such, the Company’s hedging activities are employed solely for risk management purposes. All hedging transactions are conducted with, in the opinion of management, financially stable and reputable financial institutions. As of and for the years ended December 31, 2012 and 2011, the only hedge instruments executed by the Company were associated with its exposure to fluctuations in the Indian Rupee and Canadian Dollar which result from obligations such as payroll and rent paid in these respective currencies. As of December 31, 2012, the Company only held foreign exchange contracts for the Indian Rupee; all previous Canadian Dollar foreign exchange contracts matured prior to December 31, 2012.

These derivatives are recognized on the balance sheet at their fair value. Unrealized gain positions are recorded as other current assets and unrealized loss positions are recorded as other current liabilities. Changes in the fair values of the outstanding derivatives that are highly effective are recorded in other comprehensive income until net income is affected by the variability of the cash flows of the hedged transaction. Typically, hedge ineffectiveness could result when the amount of the Company’s hedge contracts exceed the Company’s forecasted or actual transactions for which the hedge contracts were designed to hedge. Once a hedge contract matures, the associated gain (loss) on the contract will remain in other comprehensive income until the underlying hedged transaction affects net income (loss), at which time the gain (loss) will be recorded to the expense line item being hedged, which is primarily R&D. The Company only enters into derivative contracts in order to hedge foreign currency exposure, which contracts do not exceed two years from inception. If the Company entered into a contract for speculative reasons or if the Company’s current hedge position becomes ineffective, changes in the fair values of the derivatives would be recognized in earnings in the current period.

The Company assesses, both at the inception of the hedge and on an ongoing basis, whether the derivatives that are used in hedging transactions have been highly effective in offsetting changes in the cash flows of hedged items and whether those derivatives are expected to remain highly effective in future periods. For the years ended December 31, 2012 and 2011 the Company had no hedge ineffectiveness.

During the year ended December 31, 2012, the Company entered into 83 new foreign currency forward contracts, with total contractual values of $13.3 million. During the year ended December 31, 2011, the Company entered into 34 new foreign currency forward contracts, with total contractual values of $12.7 million.

A summary of the aggregate contractual or notional amounts, balance sheet location and estimated fair values of derivative financial instruments designated as cash flow hedges at December 31, 2012 is as follows (in thousands):



	Contractual / Notional Amount		Consolidated Balance Sheet Classification	Estimated Fair Value

Over the next twelve months, the Company expects to reclassify into earnings a loss of approximately $0.3 million currently recorded as other comprehensive income, as a result of the maturity of currently held forward exchange contracts.

The bank counterparties in these contracts expose the Company to credit-related losses in the event of their nonperformance. However, to mitigate that risk, the Company only contracts with counterparties who meet its minimum requirements regarding counterparty credit worthiness. In addition, the Company monitors credit ratings, credit spreads and potential downgrades prior to entering into any new hedging contracts.

Note 15 — Commitments and Contingencies

Operating Leases

Radisys is obligated under non-cancelable operating leases for certain facilities, office equipment, and vehicles. Future minimum lease payments with initial or remaining non-cancelable lease terms in excess of one year, at December 31, 2012, were as follows (in thousands):



For the Years Ending December 31,	Future Minimum Lease Payments
2013	$	3,007
2014	2,685
2015	2,633
2016	1,559
2017	782
2018 and thereafter (through 2020)	1,266
Total future minimum lease commitments	$	11,932

Rent expense totaled $5.4 million, $4.8 million and $4.2 million for the years ended December 31, 2012, 2011 and 2010.

Adverse Purchase Commitments

The Company is contractually obligated to reimburse its contract manufacturer for the cost of excess inventory used in the manufacture of the Company’s products, if there is no alternative use. This liability, referred to as adverse purchase commitments, is provided for in other accrued liabilities in the accompanying Consolidated Balance Sheets. Estimates for adverse purchase commitments are derived from reports received on a quarterly basis from the Company’s contract manufacturer. Increases to this liability are charged to cost of goods sold. When and if the Company takes possession of inventory reserved for in this liability, the liability is transferred from other accrued liabilities (Note 11—Other Accrued and Other Long-Term Liabilities) to the excess and obsolete inventory valuation allowance (Note 7—Inventories).

Guarantees and Indemnification Obligations

As permitted under Oregon law, the Company has agreements whereby it indemnifies its officers, directors and certain finance employees for certain events or occurrences while the officer, director or employee is or was serving in such capacity at

the request of the Company. The term of the indemnification period is for the officer’s, director’s or employee’s lifetime. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company has a Director and Officer insurance policy that limits its exposure and enables the Company to recover a portion of any future amounts paid. To date, the Company has not incurred any costs associated with these indemnification agreements and, as a result, management believes the estimated fair value of these indemnification agreements is minimal. Accordingly, the Company has not recorded any liabilities for these agreements as of December 31, 2012.

The Company enters into standard indemnification agreements in its ordinary course of business. Pursuant to these agreements, the Company indemnifies, holds harmless, and agrees to reimburse the indemnified party for losses suffered or incurred by the indemnified party, generally the Company’s business partners or customers, in connection with patent, copyright or other intellectual property infringement claims by any third party with respect to the Company’s current products, as well as claims relating to property damage or personal injury resulting from the performance of services by us or the Company’s subcontractors. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is generally limited. Historically, the Company’s costs to defend lawsuits or settle claims relating to such indemnity agreements have been minimal and accordingly management believes the estimated fair value of these agreements is immaterial.

Accrued Warranty

The Company provides for the estimated cost of product warranties at the time it recognizes revenue. Products are generally sold with warranty coverage for a period of 12 or 24 months after shipment. Parts and labor are covered under the terms of the warranty agreement. The workmanship of the Company’s products produced by the contract manufacturer is covered under warranties provided by the contract manufacturer for 12 months. The warranty provision is based on historical experience by product family. The Company engages in extensive product quality programs and processes, including actively monitoring and evaluating the quality of its components suppliers; however ongoing failure rates, material usage and service delivery costs incurred in correcting product failure, as well as specific product class failures out of the Company’s baseline experience, affect the estimated warranty obligation. If actual product failure rates, material usage or service delivery costs differ from estimates, revisions to the estimated warranty liability would be required.

The following is a summary of the change in the Company’s warranty accrual reserve (in thousands):



	For the Years Ended December 31,
	2012			2011
Warranty liability balance, beginning of the year	$	3,438		$	3,025
Product warranty accruals	5,332			2,987
Continuous Computing beginning balance	—			817
Adjustments for payments made	(4,816		)	(3,391		)
Warranty liability balance, end of the year	$	3,954		$	3,438

At December 31, 2012 and 2011, $3.1 million and $2.8 million of the warranty liability balance are included in other accrued liabilities and $0.8 million and $0.6 million are included in other long-term liabilities in the accompanying Consolidated Balance Sheets.

At December 31, 2012, the Company's unrecognized tax benefits associated with uncertain tax positions were $3.0 million, of which $2.6 million, if recognized, would favorably affect the effective tax rate.

The Company's ongoing practice is to recognize potential accrued interest and penalties related to unrecognized tax benefits within its global operations in income tax expense. During 2012, the Company recognized a net increase of approximately $0.2 million in potential interest and penalties associated with uncertain tax positions in the Consolidated Statements of Operations. The Company had approximately $0.4 million and $0.3 million of interest and penalties associated with uncertain tax positions at December 31, 2012, which are excluded from the unrecognized tax benefits table below.

The Company’s total amounts of unrecognized tax benefits at the beginning and end of the period are as follows (in thousands):

The Company and its subsidiaries are subject to federal income tax as well as income tax of multiple state and foreign jurisdictions. The Company's statutes of limitations are closed for all federal and state income tax years before 2009 and 2008. The statutes of limitations for the Company's other foreign subsidiaries are closed for all income tax years before 2004. The statute of limitations for the Company's Canadian subsidiary is closed for all tax years ended before 2009. However, to the extent allowed by law, the taxing authorities may have the right to examine prior periods where net operating losses and credits were generated and carried forward, and make adjustments up to the net operating loss and credit carryforward amounts. It is reasonably possible that the Company's uncertain tax positions, including interest and penalties, could decrease by approximately $0.1 million in the next twelve months.

During 2010 an Internal Revenue Service ("IRS") examination was effectively settled when the Company agreed to a Notice of Proposed Adjustment that was issued by the IRS. The Proposed Adjustment was provided in full as an uncertain tax position at December 31, 2009.

During 2011 a Canada Revenue Agency (“CRA”) examination was effectively settled when the Company agreed to the proposed adjustments issued by that CRA. The effective settlement did not have a significant impact on the Company's financial statements.

The Company is currently under tax examination in India. The periods covered under examination are the Company's financial years 2004 through 2008. The examination is in various stages of appellate proceedings and all material uncertain tax positions associated with the examination have been taken into account in the ending balance of the unrecognized tax benefits at December 31, 2012.

The Company has recorded valuation allowances of $50.2 million and $46.4 million as of December 31, 2012 and 2011. This represents a full valuation allowance against the Company's U.S. net deferred tax assets. In evaluating its valuation allowance, the Company considers all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, and recent financial performance. Based on the Company's review of all positive and negative evidence, including a three year U.S. cumulative pre-tax loss it concluded that a full valuation allowance should be recorded against its U.S. net deferred tax assets.

At December 31, 2012 and 2011, the Company had total available federal net operating loss carryforwards of approximately $112.1 million and $95.3 million. The federal and state net operating loss carryforwards expire between 2013 and 2032. The net operating losses from acquisitions are stated net of limitations pursuant to Section 382 of the Internal Revenue Code. The Company had total state net operating loss carryforwards of approximately $77.6 million and $69.6 million at December 31, 2012 and 2011. The Company also had net operating loss carryforwards of approximately $3.3 million from certain non-U.S. jurisdictions. The non-U.S. net operating loss carryforwards are primarily attributable to the United Kingdom (“U.K.”) and China. The U.K. tax losses may be carried forward indefinitely provided certain requirements are met. The Chinese tax losses may be carried forward 5 years.

The Company has federal and state research and development tax credit and other federal tax credit carryforwards of approximately $18.1 million at December 31, 2012, to reduce future income tax liabilities. The federal and Oregon tax credits expire between 2013 and 2031. The California research and development credits do not expire. The utilization of acquired credits is subject to an annual limitation pursuant to Section 383 of the Internal Revenue Code. The Company's Canadian subsidiary also had approximately $5.0 million in investment tax credit, $18.8 million in unclaimed scientific research and experimental expenditures and $7.9 million in undepreciated capital cost to be carried forward and applied against future income in Canada.

Realization of the Company's foreign deferred tax assets is dependent on generating sufficient taxable income prior to the expiration of the net operating loss and tax credit carryforwards. Although realization is not assured, management believes that it is more likely than not that the results of future operations will generate sufficient taxable income to realize the balance of the deferred tax assets, net of the valuation allowance, as of December 31, 2012. The amount of the net deferred tax assets that is considered realizable, however, could be reduced in the near term if estimates of future taxable income during the carryforward periods are reduced. Should management determine that the Company would not be able to realize all or part of the net deferred tax assets in the future, adjustments to the valuation allowance for deferred tax assets may be required.

During 2012, the Company repatriated $21.3 million in cash from selected foreign subsidiaries of which $19.2 million was in the form of a dividend and the remaining $2.1 million was a return of capital. The company has provided a deferred tax liability of $0.1 million related to $0.3 million of unremitted earnings of select foreign subsidiaries. The Company plans to indefinitely reinvest the earnings of certain foreign subsidiaries. Should the Company repatriate any foreign earnings from the

remaining subsidiaries in the future, it may be required to establish an income tax liability and recognize additional income tax expense related to such earnings. The Company has indefinitely reinvested approximately $11.9 million of undistributed earnings from the foreign subsidiaries at December 31, 2012. No provision has been made for the U.S., state or additional foreign income taxes related to to the undistributed earnings and it is not practicable to determine the U.S. federal income tax liability, if any, which would be payable if such earnings were not permanently reinvested outside the U.S.

Pretax book loss from domestic operations for the fiscal years 2012, 2011, and 2010 was $55.8 million, $23.2 million, and $12.8 million. Pretax book income from foreign operations for the fiscal years 2012, 2011, and 2010 was $14.9 million, $10.5 million, and $11.9 million.

The American Taxpayer Relief Act of 2012, which reinstated the United States federal research and development tax credit retroactively from January 1, 2012 through December 31, 2013, was not enacted into law until the first quarter of 2013. Therefore, the expected tax benefit resulting from such reinstatement for 2012 will not be reflected in the Company's annual effective tax rate until 2013.

Note 18 — Employee Benefit Plans

Stock-Based Employee Benefit Plans

Equity instruments are granted to employees, directors and consultants in certain instances, as defined in the respective plan agreements.

Stock Options and Restricted Stock Awards

On May 15, 2007, the Company's shareholders approved the 2007 Stock Plan (as amended, the "2007 Stock Plan") which provides for issuance of stock options, restricted shares, restricted stock units and performance-based awards. Under the 2007 Stock Plan, 5,450,000 shares have been reserved and authorized for issuance to any non-employee directors and employees. The 2007 Stock Plan provides the Board of Directors discretion in creating employee equity incentives. Unless otherwise stipulated in the plan document, the Board of Directors determines stock option exercise prices, which may not be less than the fair value of Radisys common stock at the date of grant, vesting periods and the expiration periods which are a maximum of 10 years from the date of grant for certain awards.

In November 2009, the Company completed a stock option exchange program. The Company's eligible employees were permitted to exchange some or all of their outstanding options, with an exercise price greater than $9.44 per share (which is equal to the 52-week high closing price of the Company's common stock as of the start of this offer), that were granted on or before October 5, 2008, whether vested or unvested, for restricted stock units, except for employees in Canada who received new stock options with new vesting schedules and exercise prices. All employees of Radisys and its subsidiaries, other than members of the Company's Board of Directors, executive officers and employees located in the Netherlands and Israel were eligible to participate in the exchange offer. The option exchange took place on November 3, 2009. Pursuant to the option exchange 848,800 eligible options were canceled and replaced with 169,600 restricted stock units and 35,000 stock options. The new restricted stock units and stock options have a new three year vesting period that began on November 3, 2009. The exchange resulted in $0.2 million in additional stock compensation expense which was recognized over the new three year vesting period.

On August 17, 2010, the shareholders approved the LTIP. The LTIP provides for the grants of awards payable in shares of common stock or cash upon the achievement of performance goals set by the Company’s Compensation and Development Committee (“the Committee”). The number of shares of the Company’s common stock initially reserved for issuance under the LTIP is 2,000,000 shares with a maximum of 500,000 shares in any calendar year to one participant.

On May 3, 2011 the Company registered 600,000 shares of its common stock under the RadiSys Corporation Inducement Stock Plan for CCPU Employees (the "CCPU Plan"). The CCPU Plan was adopted without shareholder approval in reliance upon the exception provided under NASDAQ Listing Rule 5635(c)(4) relating to awards granted in connection with the hiring of new employees, including grants to transferred employees in connection with a merger or acquisition. Awards under the CCPU Plan are made only to employees of Continuous Computing or its subsidiaries and became effective upon the completion of the Continuous Computing acquisition. The CCPU Plan provides for the issuance of stock options, restricted shares and restricted stock units. In 2011, the Company issued 368,000 shares under the CCPU Plan and no future awards will be granted.

The Company assumed the stock plans of Continuous Computing on July 8, 2011. Under the terms of the Company's merger agreement with Continuous Computing, options outstanding under these plans were converted to options to purchase shares of the Company's common stock. Options issued under these plans vest over four years from the original grant date and have an expiration date of 10 years from the original grant date. The exercise price of each converted option is equal to the product of the original exercise price and the original number of options granted divided by the number of converted options received. These stock plans have been suspended and no future awards will be granted under these plans. A total of 319,000 shares of common stock were issued under the Continuous Computing stock plans.

In accordance with the merger agreement with Continuous Computing, unvested options pursuant to the Continuous Computing plans were required to be converted into multiple awards on the acquisition date, with the resulting awards becoming non-contingent and contingent options of the Company. Both the non-contingent and contingent awards continue to vest under the original service conditions of the awards. However, the contingent awards contain post-vesting restrictions tied to payment of certain merger contingencies such as the earn-out and indemnification agreements. The assumed options were valued using a Black-Scholes option-pricing model. In addition, the Company utilized the Finnerty Asian Put Option Approach to estimate the discount associated with the post-vesting restrictions for the contingent options. The resulting discount applied was 10%.

On September 4, 2012, the Committee approved 291,375 performance based restricted stock awards under the Overlay Plan based on attainment of the performance goals at maximum levels. The Overlay provides for the grants of awards payable in shares of common stock upon the achievement of performance goals set by the Committee. The awards have four separate quarterly performance achievement dates in 2013 and vest one year after they are earned.

Effective September 10, 2012, the Committee canceled all outstanding awards under the LTIP, resulting in the shares underlying such awards becoming eligible for grants of additional awards under the LTIP.

Following such cancellation of awards, on September 10, 2012, the Committee approved 799,975 performance based restricted stock awards under the LTIP based on attainment of 100% of the performance goals being met. The LTIP provides for the grants of awards payable in shares of common stock upon the achievement of performance goals set by the Committee. The awards have four separate semi-annual performance achievement dates in 2013 and 2014 and vest upon attainment of the performance conditions. In addition to the performance conditions, the awards contain market-based multipliers based on the average price of the Company's common stock thirty days prior to each semi-annual performance period. The maximum multiplier for a given semi-annual performance period is 2.75x the original grant and limited to a maximum of 2.5x (or 1,999,938 shares) over the entire performance period.

As of December 31, 2012, the Company had 737,506 common shares available for future grant under its equity plans.

The following table summarizes stock option activity for 2012 (in thousands, except average prices and weighted average remaining contractual lives):



	Options		Weighted-Average Exercise Price		Weighted-Average Remaining Contractual Term (Years)	Aggregate Intrinsic Value

Options vested as of December 31, 2012 and expected to vest after December 31, 2012	2,495		$	7.93	3.69	$	477

The aggregate intrinsic value in the table above represents the total pretax value, based on the Company's closing common stock price of $2.98 at December 31, 2012 that would have been received by the option holders had all option holders exercised their in-the-money options on December 31, 2012.

Total intrinsic value of options exercised for the years ended December 31, 2012, 2011 and 2010 was $0.1 million, $0.1 million, and $0.1 million. The total amount of cash received from the exercise of options in 2012, 2011 and 2010 was $0.1 million, $0.1 million and $0.5 million.

As of December 31, 2012, the Company had $2.6 million in unrecognized compensation expense related to stock options which is expected to be recognized over a weighted-average period of 2.4 years.

The following table summarizes nonvested stock activity for 2012:



	Restricted Stock Units				LTIP and Overlay Awards
	Restricted Shares		Weighted-Average Fair Value		Restricted Shares		Weighted-Average Fair Value
Balance, December 31, 2011	510		$	7.68	844		$	8.33

Balance, December 31, 2012	527		$	5.65	1,003		$	2.19

The total fair value of restricted stock units that vested in 2012, 2011 and 2010 was $0.8 million, $1.0 million and $1.5 million. As of December 31, 2012, the Company had $2.2 million in unrecognized compensation expense related to restricted stock units which is expected to be recognized over a weighted-average period of 1.5 years. The LTIP and Overlay awards are separated into four performance periods which range from September 10, 2012 to December 31, 2014. Expense associated with each service periods is measured on the date the respective service period begins. At December 31, 2012, the Company had $0.5 million in unrecognized compensation expense associated with the first performance periods of the LTIP and Overlay awards which is expected to be recognized over a weighted-average period of 0.7 years.

Employee Stock Purchase Plan

In December 1995, the Company established an Employee Stock Purchase Plan (“ESPP”). All employees of Radisys and its subsidiaries who customarily work 20 or more hours per week, including all officers, are eligible to participate in the ESPP. Separate offerings of common stock to eligible employees under the ESPP (an “Offering”) commence on February 15, May 15, August 15 and November 15 of each calendar year (“Enrollment Dates”) and continue for a period of 18 months. Multiple separate Offerings are in operation under the ESPP at any given time. An employee may participate in only one Offering at a time and may purchase shares only through payroll deductions permitted under the provisions stipulated by the ESPP. The purchase price is the lesser of 85% of the fair market value of the common stock on date of grant or that of the purchase date (“look-back feature”). Pursuant to the provisions of the ESPP, as amended, the Company is authorized to issue up to 6.4 million shares of common stock under the ESPP. At December 31, 2012, 970,078 shares were available for issuance under the ESPP.

During the second quarter of 2009, the Board of Directors approved an amendment to the Company’s ESPP to provide for a one-year holding period with respect to common stock shares purchased by participants under the ESPP. The one-year holding period took effect during the fourth quarter of 2009. Due to the holding period, the Company applies a discount to the ESPP stock compensation to reflect the decreased liquidity. The Company utilizes the Finnerty Asian Put Option Approach to estimate the discount. Inputs for the model include the length of the holding period, volatility and risk-free rate. The discount applied in the fourth quarter of 2012 was 13.0%.

The following table summarizes shares issued under the ESPP (in thousands, except per share amounts):



	Year Ended December 31,
	2012		2011		2010
Shares issued pursuant to the ESPP	352		251		311
Cash received for the purchase of shares pursuant to the ESPP	$	1,225	$	1,572	$	2,049
Weighted-average purchase price per share	$	3.48	$	6.27	$	6.6

Stock-Based Compensation Expense

The Company uses the Black-Scholes model to measure the grant-date fair value of stock options and ESPP shares. The grant-date fair value of stock options that are expected to vest is recognized on a straight-line basis over the requisite service period, generally, three years. The grant date fair value of ESPP shares that are expected to vest is recognized on a straight-line basis over the requisite service period, generally, 18 months, subject to modification at the date of purchase due to the ESPP look-back feature. The estimate of the number of options, ESPP shares and restricted stock units granted under the 2007 Stock Plan expected to vest is determined based on historical experience.

The Company estimates the fair value of stock options and purchase rights under the ESPP using a Black-Scholes option-pricing model. The calculation includes several assumptions that require management’s judgment. The expected term of the option or share is determined based on assumptions about patterns of employee exercises, and represents a probability-weighted-average time period from grant until exercise of stock options, subject to information available at time of grant. Determining expected volatility generally begins with calculating historical volatility for a similar long-term period and then considering the ways in which the future is reasonably expected to differ from the past.

The Company uses one employee population. The expected term computation is based on historical vested option exercise and post-vest forfeiture patterns and is also factored by an estimate of the expected term for fully vested and outstanding options. The estimate of the expected term for options that were fully vested and outstanding was determined as the midpoint between the evaluation date and the contractual term date of the option.

The risk free interest rate is based on the U.S. Treasury constant maturities in effect at the time of grant for the expected term of the option or share.

The fair value of nonvested stock is the market value as of the grant date. The grant-date fair value of the restricted stock units that are expected to vest is recognized on a straight-line basis over the requisite service period, which is three years. The grant-date fair value of the LTIP and Overlay awards is recognized ratably over the service period which equals the measurement period of the award. The measurement period is the period of time over which performance objectives are expected to be achieved. Since the number of shares that may be issued under the LTIP and Overlay and the service period are both variable, the Company reevaluates the LTIP and Overlay awards on a quarterly basis and adjusts the number of shares expected to be awarded based upon financial results of the Company as compared to the performance goals set for the award. Adjustments to the number of shares awarded, and to the corresponding compensation expense, are made on a cumulative basis at the date of adjustment based upon the estimated probable number of shares to be awarded. Adjustments made to compensation expense resulting from a change in the estimated probable vesting date of the awards are made on a prospective basis. Additionally, under the 2012 LTIP the Company is required to measure the fair value of the market-based condition contained in the awards. This fair value of this feature is measured at the outset of each semi-annual performance period and recognized over the service period of the respective performance period.

The fair value calculations for stock options and ESPP shares used the following assumptions for the years ended December 31:



	Stock Options									Assumed Options			Employee Stock Purchase Plan

401(k) Savings Plan

The Company established a 401(k) Savings Plan (“401(k) Plan”), a defined contribution plan, as of January 1, 1989 and amended through January 1, 2007, in compliance with Section 401(k) and other related sections of the Internal Revenue Code and corresponding Regulations issued by the Department of Treasury and Section 404(c) of Employee Retirement Income Security Act of 1974 (“ERISA”), to provide retirement benefits for its U.S employees. Under the provisions of the plan, eligible employees are allowed pre-tax contributions of up to 30% of their annual compensation or the maximum amount permitted by the applicable statutes. Additionally, eligible employees can elect to make catch-up contributions, within the limits set forth by pre-tax contributions, or to the maximum amount permitted by the applicable statutes. Pursuant to the provisions of the 401(k) Plan, the Company may contribute 50% of pre-tax contributions made by eligible employees, adjusted for loans and withdrawals, up to 6% of annual compensation for each eligible employee. The Company may elect to make supplemental contributions as periodically determined by the Board of Directors at their discretion. The contributions made by the Company on behalf of eligible employees become 100% vested after three years of service, or 33% per year after one year of service. The Company’s total contributions to the 401(k) Plan amounted to $0.7 million, $0.7 million, and $0.9 million in 2012, 2011 and 2010, respectively. In addition, some of the Company’s employees outside the U.S are covered by various defined contribution plans, in compliance with the statutes of respective countries. The participants pay for the 401(k) Plan administrative expenses.

Deferred Compensation Plan

The Company has a Deferred Compensation Plan, providing its directors and certain eligible employees with opportunities to defer a portion of their compensation as defined by the provisions of the plan. The Company credits additional amounts to the deferred compensation plan to make up for reductions of Company contributions under the 401(k) Plan. The deferred amounts are credited with earnings and losses under investment options chosen by the participants. The Company sets aside deferred amounts, which are then invested in long-term insurance contracts. All deferred amounts and earnings are 100% vested at all times, but are subject to the claims of creditors of the Company under a bankruptcy proceeding. Benefits are payable to a participant upon retirement, death, and termination of employment and paid as elected by the participant in accordance with the terms of the plan. The Plan also permits scheduled in-service distributions. Deferred amounts may be withdrawn by the participant in case of financial hardship as defined in the plan agreement.

Note 19 — Segment Information

The Company's Chief Operating Decision Maker (CODM), Radisys' Chief Executive Officer, reviews the Company's results of operations on a consolidated level. Therefore, the Company is one operating segment. Key resources, decisions, and assessment of performance are also analyzed on a company-wide level.
