NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1 — Significant Accounting Policies

Radisys Corporation (the “Company” or “Radisys”) has adhered to the accounting policies set forth in its Annual Report on Form 10-K for the year ended December 31, 2013 in preparing the accompanying interim condensed consolidated financial statements. The preparation of these statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosure of contingent assets and liabilities. Actual results could differ from those estimates. Additionally, the accompanying financial data as of June 30, 2014 and for the three and six months ended June 30, 2014 and 2013 has been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2013.

Certain prior year balances have been reclassified to conform to the current year’s presentation. Such reclassifications did not affect total cash flows, total net revenues, operating loss, net loss, total assets, total liabilities or shareholders’ equity.

The financial information included herein reflects all normal recurring adjustments that are, in the opinion of management, necessary for a fair presentation of the results for interim periods.

On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for the Company on January 1, 2017. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.

Note 2 — Fair Value of Financial Instruments

Assets and Liabilities Measured at Fair Value on a Recurring Basis

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 and deferred compensation liability are 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 Corporation ("Continuous Computing") based on the amount of product royalty revenues to be generated by a

7

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 increase or decrease accordingly in amounts that will vary based on the timing of the projected revenues and the timing of the expected payments.

The following table summarizes the fair value measurements for the Company's financial instruments (in thousands):

	Fair Value Measurements as of June 30, 2014
	Total			Level 1		Level 2			Level 3
Cash surrender value of life insurance contracts (A)	$	1,873		$	—	$	1,873		$	—

Restructuring and other charges, net	$	815		$	(114	)	$	2,115		$	1,156

Restructuring and other charges includes expenses incurred for employee terminations due to a reduction of personnel resources resulting from modifications of business strategy or business emphasis. Employee-related restructuring expenses include severance benefits, notice pay and outplacement services. Restructuring and other charges may also include expenses incurred associated with acquisition or divestiture activities, facility abandonments and other expenses associated with business restructuring actions.

For the three months ended June 30, 2014, the Company recorded the following restructuring charges:

• $0.4 million net expense relating to the severance of employees in connection with the previously reported Penang site closure, as well as severance for two additional employees, net of reductions resulting from changes in previously estimated amounts for employee severance and associated payroll costs;

• $0.5 million integration-related net expense principally associated with asset disposals and personnel overlap resulting from resource consolidation primarily associated with the Penang site closure; and

The Company evaluates the adequacy of the accrued restructuring charges on a quarterly basis. Reversals are recorded in the period in which the Company determines that expected restructuring obligations are less than the amounts accrued.

Note 6 — Short-Term Borrowings

Silicon Valley Bank

At the beginning of the first quarter of 2014, the Company had a $35.0 million secured revolving line of credit agreement (as amended, the "Agreement") with Silicon Valley Bank ("SVB") with a stated maturity date of July 28, 2016. On March 14, 2014, the Company entered into an amended and restated $25.0 million revolving line of credit agreement with SVB (as amended, the "2014 Agreement") that replaces the Agreement and has a stated maturity date of July 28, 2016. On May 30, 2014 the 2014 Agreement was amended to increase the letter of credit sublimit under the secured revolving credit facility from $1,000,000 to $2,000,000. The secured revolving credit facility under the 2014 Agreement is available for cash borrowings and is subject to a borrowing formula based upon eligible accounts receivable less outstanding letters of credit (aggregate letters of credit are not to exceed $2,000,000). Eligible accounts receivable include 80% of U.S. and 65% of foreign accounts receivable (80% in certain cases), not greater than 60 days past original invoice date. The interest rate is dependent upon the Company's Liquidity (as defined in the 2014 Agreement) when compared to a pre-determined threshold (the "Liquidity Threshold"), which is defined in the 2014 Agreement as $15.0 million, with the exception of the last month end of each quarter, where it is defined as $20.0 million. Liquidity is calculated under the 2014 Agreement as unrestricted cash plus unused availability on the revolving line of credit; however, if the Company's 4.50% convertible senior notes due 2015 (the "2015 convertible senior notes") are not renewed or refinanced 120 days prior to their maturity date, which is February 15, 2015, Liquidity (for purposes of testing against the Liquidity Threshold) will be reduced by the outstanding principal amount of the 2015 convertible senior notes. The calculation of interest under the 2014 Agreement is as follows:

• When Liquidity is above the Liquidity Threshold, the interest rate is the prime rate (as published in Wall Street Journal) plus 0.75%; and

• When Liquidity is below the Liquidity Threshold, the interest rate is the prime rate (as published in Wall Street Journal) plus 2.25%.

Under the 2014 Agreement, the Company is required to make interest payments monthly. The Company was further required to pay a loan modification fee of $35,000 and will be required to pay a commitment fee equal to $35,000 on July 29, 2014 and annually thereafter. Under the 2014 Agreement the Company is required to pay the higher of actual monthly interest incurred or the interest equivalent of $10.0 million in average monthly borrowings. If the Company terminates the commitment

under the 2014 Agreement prior to the maturity date, the Company is required to pay a cancellation fee equal to 1.5% of the commitment under the 2014 Agreement.

The 2014 Agreement requires the Company to make certain representations, warranties and other agreements that are customary in credit agreements of this type. The 2014 Agreement also includes a financial covenant that requires the Company to maintain minimum Liquidity of $10.0 million tested monthly.

As of June 30, 2014 and December 31, 2013, the Company had outstanding balances of $10.0 million and $15.0 million under the 2014 Agreement and the Agreement, respectively. At June 30, 2014, the Company had $14.0 million of total borrowing availability remaining under the 2014 Agreement.

On July 9, 2014, the Company entered into a letter agreement (the "letter agreement") with SVB relating to the Company's amended and restated $25.0 million secured revolving line of credit. The 2014 Agreement includes an Operating Accounts covenant stating that the Company and its subsidiaries may hold no more than $8.0 million in accounts maintained at financial institutions outside of the United States through August 31, 2014. As of June 30, 2014, the amount of cash held by the Company and its subsidiaries in accounts maintained at financial institutions outside of the United States was $9.0 million. Pursuant to the terms of the letter agreement, the Company obtained a waiver from SVB of the requirement to comply with the Operating Accounts covenant. After giving effect to the waiver, the Company was in compliance with all covenants under the 2014 Agreement.

Note 7 — Convertible Debt

2013 Convertible Senior Notes

On February 15, 2013, the Company repaid at maturity the entire outstanding balance of the 2.75% convertible senior notes due 2013 (the "2013 convertible senior notes") 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 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 June 30, 2014 and December 31, 2013, the Company had outstanding 2015 convertible senior notes with a face value of $18.0 million. As of June 30, 2014 and December 31, 2013, the fair values of our 2015 convertible senior notes were $17.9 million and $17.8 million, which are based on the most recent quoted prices of the Company's publicly traded debt on each balance sheet date.

The following table outlines the effective interest rate, contractually stated interest costs, and costs related to the amortization of issuance costs for the Company's 2013 and 2015 convertible senior notes:

Note 8 — Commitments and Contingencies

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 presented in other accrued liabilities in the accompanying Condensed 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 sales. If and when the Company takes possession of inventory reserved for in this liability, the liability is transferred from other accrued liabilities to the excess and obsolete inventory valuation allowance (Note 4 —Inventories).

In November 2013, the Company notified its existing contract manufacturer of the Company's intent to transition manufacturing to another contract manufacturer co-located with the Company's Shenzhen site. Upon notification of intent to terminate the relationship, the manufacturing agreement contractually obligates the Company to purchase all inventories in excess of ninety days demand. As of June 30, 2014 the existing contract manufacturer had yet to invoke this clause and therefore an inventory deposit and offsetting liability have not been reflected on the Condensed Consolidated Balance Sheets. The value of the potential liability in excess of the current adverse purchase commitment was $4.4 million at June 30, 2014.

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 an 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 June 30, 2014.

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 the 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

13

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):

	Six Months Ended
	June 30,
	2014			2013
Warranty liability balance, beginning of the period	$	3,328		$	3,954
Product warranty accruals	1,219			1,899
Utilization of accrual	(1,604		)	(2,183		)
Warranty liability balance, end of the period	$	2,943		$	3,670

At June 30, 2014 and December 31, 2013, $2.3 million and $2.6 million of the warranty liability balance was included in other accrued liabilities and $0.6 million and $0.7 million was included in other long-term liabilities in the accompanying Condensed Consolidated Balance Sheets.

(A) For the three months ended June 30, 2014 there were no remaining contingently issuable shares outstanding. For the six months ended June 30, 2013, 30,000 contingently issuable shares were excluded from the calculation as their effect would have been anti-dilutive.

(B) For each of the three months ended June 30, 2014 and 2013, 2.1 million as-if converted shares associated with the Company's convertible senior notes were excluded from the calculation as their effect would have been anti-dilutive. For the six months ended June 30, 2014 and 2013, 2.1 million and 2.4 million as-if converted shares associated with the Company's convertible senior notes were excluded from the calculation as their effect would have been anti-dilutive.

14

(C) For the three and six months ended June 30, 2014 and 2013, the following equity awards, by type, were excluded from the calculation, as their effect would have been anti-dilutive (in thousands):

	Three Months Ended		Six Months Ended
	June 30,		June 30,
	2014	2013	2014	2013

Performance based restricted stock units (D)	409	2,087	409	2,087
Total equity award shares excluded	3,751	4,903	3,751	4,903

(D) Shares under the Long-Term Incentive Plan ("LTIP") are presented 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 Company's Compensation and Development Committee. 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 the end of each semi-annual performance period. The maximum multiplier for a given semi-annual performance period is 2.75x the original grant and overall achievement is limited to a maximum of 2.5x of the target award over the entire performance period. Based on this formula, the maximum number of shares that could be earned was 0.8 million and 2.0 million for the three months ended June 30, 2014 and 2013.

Note 10 — Income Taxes

The Company's effective tax rate for the three months ended June 30, 2014 differs from the statutory rate due to a full valuation allowance provided against its United States (“U.S.”) net deferred tax assets, a partial valuation allowance against Canadian deferred tax assets, and taxes on foreign income that differ from the U.S. tax rate. The Company’s effective tax rate for the three months ended June 30, 2013 differs from the statutory rate due the full valuation allowance provided against its U.S. net deferred tax assets, Canadian research and experimental development claims, and taxes on foreign income that differ from the U.S. tax rate.

The Company utilizes the asset and liability method of accounting for income taxes. The Company records deferred tax assets to the extent it believes these assets will more likely than not be realized. In making such determination, 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 upon the Company's review of all positive and negative evidence, including its three year U.S. cumulative pre-tax book loss and taxable loss, it concluded that a full and a partial valuation allowance should continue to be recorded against its U.S. and Canadian net deferred tax assets at June 30, 2014. In certain other foreign jurisdictions, where the Company does not have cumulative losses or other negative evidence, the Company had net deferred tax assets of $3.6 million and $3.8 million at June 30, 2014 and December 31, 2013. In the future, if the Company determines that it is more likely than not that it will realize its U.S. and Canadian net deferred tax assets, it will reverse the applicable portion of the valuation allowance and recognize an income tax benefit in the period in which such determination is made.

The Company's unrecognized tax benefits and related interest and penalties during the three months ended June 30, 2014 increased by $0.3 million primarily due to new uncertain tax exposures. The ending balance for the unrecognized tax benefits was approximately $3.9 million at June 30, 2014. The related interest and penalties were $0.5 million and $0.3 million. The uncertain tax positions that are reasonably possible to decrease in the next twelve months are insignificant.

The Company is currently under tax examination in India. The periods covered under examination are the Company's financial years 2005 through 2007 and 2009 through 2010. 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 June 30, 2014. As of June 30, 2014, the Company is not under examination by tax authorities in any other jurisdictions.

The LTIP provides for the grants of awards payable in shares of common stock upon the achievement of performance goals set by the Company's Compensation and Development Committee. 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 the end of each semi-annual performance period. The maximum multiplier for a given semi-annual performance period is 2.75x the original grant and overall achievement is limited to a maximum of 2.5x of the target award over the entire performance period.

Note 12 — Hedging

The Company’s 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 June 30, 2014 and December 31, 2013, the only hedge instruments executed by the Company are associated with its exposure to fluctuations in the Indian Rupee, which result from obligations such as payroll and rent paid in this currency.

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 (loss) until the underlying hedged transaction affects net income (loss), at which time the gain (loss) will be reclassified out of accumulated other comprehensive income (loss) and recorded to the expense line item being hedged. The Company only enters into derivative contracts in order to hedge foreign currency exposure, and these 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

16

derivatives are expected to remain highly effective in future periods. For the three and six months ended June 30, 2014 and 2013 and for the year ended December 31, 2013, the Company had no hedge ineffectiveness.

During the three months ended June 30, 2014 and 2013 and for the six months ended June 30, 2014, the Company did not enter into any new hedging contracts. During the six months ended 2013, the Company entered into 12 new foreign currency forward contracts with total notional contractual values of $2.5 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 June 30, 2014 is as follows (in thousands):

	Contractual/ Notional Amount		Condensed Consolidated Balance Sheet Classification	Estimated Fair Value
Type of Cash Flow Hedge				Asset		(Liability)
Foreign currency forward exchange contracts	$	8,966	Other current assets	$	662	$	—

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, 2013 is as follows (in thousands):

Amounts reclassified from other comprehensive income (loss)	98			178			397			356
Other comprehensive income (loss)	92			(756		)	607			(648		)
Ending balance of unrealized loss on forward exchange contracts	$	(268	)	$	(1,413	)	$	(268	)	$	(1,413	)

Over the next twelve months, the Company expects to reclassify into earnings a gain of approximately $0.1 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 13 — Segment Information

The Company's Chief Operating Decision Maker, Radisys' Chief Executive Officer, reviews the Company's results of operations on a consolidated level, and executive staff is structured by function rather than by product category. Additionally, key resources, decisions, and assessment of performance are also analyzed on a company-wide level. Due to these factors, the Company is one operating segment.

Generally, the Company's customers are not the end-users of its products. The Company ultimately derives revenues from the following four product groups (in thousands):

When these products are combined with our professional service organization of network experts, we believe our technology enables our customers to bring to market solutions such as intelligent gateways (security, femto, and LTE gateways), intelligent switches and load balancers, at a cost and time to market advantage when compared to internally developed solutions;

• Trillium software is the protocol foundation for a complete turn-key application that enables the communication linkage between end user wireless devices and the small cell base stations carriers utilize to optimize radio access spectrum utilization and coverage in both the 3G and LTE networks. Our focus is in providing the software to enable 3G and LTE operator-controlled and low-power wireless base stations that provide improved cellular coverage, capacity and applications for homes and enterprises as well as metropolitan and rural public places (known as small cells, femtocells and metrocells); and

• We leverage the same Trillium technology to enable small cell applications in adjacent markets such as aerospace and defense as well as manufacturing and test.

Three and Six Months Ended June 30, 2014 Summary

As expected, our first half and second quarter 2014 revenues declined primarily as a result of prior business decisions to exit certain product lines, certain products reaching end of life and the inconsistent customer order patterns within our Software-Solutions product line. Additionally, continued delays in the deployment of next generation wireless networks and the release of required spectrum in certain geographies to support these networks has adversely affected our ability to offset the aforementioned impacts. Despite these challenges, second quarter 2014 revenue increased $6.2 million or 14.1% sequentially from the first quarter 2014 from $43.8 million to $50.0 million and net loss per share decreased sequentially from $0.35 to $0.23. This was driven by a $3.0 million increase in our COM Express and Rackmount Server product group due primarily to sales of end of life products and a $2.6 million increase in our Software-Solutions product group due to growth in our targeted VoLTE MRF products as our customers and partners have begun deploying VoLTE applications in their networks. We expect third quarter revenue to be between $48.0 million and $54.0 million and net loss per share to range from $0.18 to $0.06.

Over the first half of 2014, we have begun to realize the benefits of management's 2013 cost reduction actions. Such actions resulted in reduced second quarter 2014 R&D and SG&A expense by a combined $4.2 million, or 19.4%, in the three months ended June 30, 2014 when compared to the same period in 2013. We expect R&D and SG&A expense to approximate $17.4 million in the third quarter 2014. Our contract manufacturing transition remains on track and is scheduled for completion in the third quarter of 2014. This transition will ultimately enable the closure of our Penang facility and is expected to result in approximately $6 million, or 300 basis points ("bps") of gross margin, in annual savings in cost of goods sold as we exit 2014.

The following is a summary-level comparison of the three months ended June 30, 2014 and 2013:

• Revenues decreased $15.4 million to $50.0 million for the three months ended June 30, 2014 from $65.4 million for the three months ended June 30, 2013. Included in this decrease was a combined $4.5 million decline in our Other Products and COM Express and Rackmount Server product groups as certain of these products have been trending towards end of life as a result of prior strategic decisions to manage those products for cash. Sales from our ATCA product group also declined $8.8 million due to fewer current year network deployments combined with prior business decisions to exit low margin blade-only products. Sales of our Software-Solutions products declined $2.2 million primarily due to fewer audio conferencing shipments, including to a top five customer, which adversely affected revenues of our MRF product line.

20

• Our gross margin decreased 570 "bps" in the three months ended June 30, 2014 to 24.0% from 29.7% of revenue in the three months ended June 30, 2013. Unfavorable sales mix, which was driven by decreased sales in our higher margin Software-Solutions product group, was responsible for approximately 320 bps of the decrease. Additionally, the decrease in overall revenue levels absorbed a lower percentage of our fixed costs, which was responsible for 180 bps of the decrease.

• R&D expense decreased $3.6 million to $8.4 million for the three months ended June 30, 2014 from $12.0 million for the three months ended June 30, 2013. This decrease is attributable to the cost-saving actions we undertook in the second half of 2013, which included the closure of our Shanghai and Penang development sites.

• SG&A expense decreased $0.5 million to $9.0 million for the three months ended June 30, 2014 from $9.5 million for the three months ended June 30, 2013. This decrease was the result of payroll, commissions, and facility expense reductions due to decreased headcount, lower sales, and site consolidation.

• Cash and cash equivalents increased $9.1 million to $34.6 million at June 30, 2014 from $25.5 million at December 31, 2013. We raised $20.6 million in cash as a result of a public offering of our common stock during the first quarter of 2014. This increase was offset by consumption of $5.3 million of cash used in operations (including $2.0 million in cash restructuring payments) and $1.3 million of cash used for capital expenditures. Further, during the second quarter of 2014 we repaid $5.0 million in debt that was previously outstanding under our Silicon Valley Bank line of credit.

Revenues

The following table sets forth our revenues by product group for the three and six months ended June 30, 2014 and 2013 (in thousands):

	Three Months Ended						Six Months Ended
	June 30,						June 30,
	2014		2013		Change		2014		2013		Change
ATCA Platforms	$	22,966	$	31,722	(27.6	)%	$	46,158	$	66,540	(30.6	)%
Software-Solutions	10,400		12,612		(17.5	)	18,241		24,261		(24.8	)
COM Express and Rackmount Server	13,456		14,218		(5.4	)	23,917		28,845		(17.1	)
Other Products	3,142		6,886		(54.4	)	5,447		13,970		(61.0	)
Total revenues	$	49,964	$	65,438	(23.5	)%	$	93,763	$	133,616	(29.8	)%

Revenues in the ATCA product group decreased $8.8 million for the three months ended June 30, 2014 from the comparable period in 2013. This was driven by a $6.0 million decrease in revenues from North American customers due to last time buys that were substantially completed in the first half of 2013 and fewer current year network deployments.

Revenues in the ATCA product group decreased $20.4 million for the six months ended June 30, 2014 from the comparable period in 2013. This was driven by a $11.6 million decrease in revenues from North American customers due to fewer current year network deployments and last time buys. Additionally, Asia Pacific revenues decreased $9.0 million due to LTE deployments in Japan that were substantially complete in the second half of 2013.

Revenues in the Software-Solutions product group decreased $2.2 million and $6.0 million for the three and six months ended June 30, 2014 from the comparable periods in 2013. The decrease is attributable to the timing of MRF deployments for use in audio conferencing applications during the first half of 2013 which were not repeated in 2014. Specifically, a top five customer has shifted its port redundancy strategy to more efficiently use previously licensed ports throughout their network rather than purchasing additional ports to support increased network usage. The decrease in audio conferencing revenue was offset by revenue growth of $2.0 million and $1.7 million for the three and six months ended June 30, 2014 from the comparable periods in 2013 in our targeted VoLTE MRF products as our customers and partners have begun deploying VoLTE applications in their networks.

Revenues in the COM Express and Rackmount Server product group decreased $0.8 million for the three months ended June 30, 2014 from the comparable period in 2013 as the result of our strategic decision to manage for cash the value-line of our COM Express modules. The decline was offset by $2.8 million in last time buys from a top five customer.

Revenues in the COM Express and Rackmount Server product group decreased $4.9 million for the six months ended June 30, 2014 from the comparable period in 2013 as the result of our strategic decision to manage for cash the value-line of our COM Express modules. The decline was offset by a $0.5 million in last time buys from a top five customer in the second quarter of 2014.

Revenues in the Other Products product group decreased $3.7 million and $8.5 million for the three and six months ended June 30, 2014 from the comparable periods in 2013. The decline in revenues was expected by management as these hardware-centric products trend towards end of life and our largest customer continues to transition to next-generation network elements.

EMEA	29.5		23.7		25.8		22.8
Total	100.0	%	100.0	%	100.0	%	100.0	%

North America. Revenues from the North America region decreased $10.9 million and $20.8 million for the three and six months ended June 30, 2014 from the comparable periods in 2013. Revenues from our ATCA product group decreased $4.2 million and $9.0 million as a result of fewer current year network deployments and last time buys. Similarly, COM Express and Rackmount Server product group sales decreased $2.4 million and $5.2 million as the result of our strategic decision to manage for cash the value-line of our COM Express modules. In addition, our Software-Solutions product group sales decreased $1.9 million and $3.1 million due to the timing of MRF deployments for use in audio conferencing applications during the first half of 2013 which were not repeated in 2014. The decrease in audio conferencing revenue was offset by revenue growth of $0.9 million and $1.7 million for the three and six months ended June 30, 2014 from the comparable periods in 2013 in our targeted VoLTE MRF products.

Asia Pacific. Revenues from the Asia Pacific region decreased $3.8 million and $12.9 million for the three and six months ended June 30, 2014 from the comparable periods in 2013. Revenues a major customer using our products to deploy next-generation wireless networks in Japan decreased $2.9 million and $6.7 million as these projects were substantially completed by the end of 2013.

EMEA. Revenues from the EMEA region decreased $0.7 million and $6.2 million for the three and six months ended June 30, 2014 from the comparable periods in 2013 due to $4.3 million and $7.7 million decreases from our Other Products product group as these hardware-centric products trend towards end of life and our largest customer continues to transition to next-generation network elements. In the second quarter of 2014, the decline was offset by a $2.8 million COM Express and Rackmount Server product group last time buy from a top five customer.

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

Gross Margin

The following table summarizes our cost of sales and gross margin for the three and six months ended June 30, 2014 and 2013 (in thousands):

	Three Months Ended								Six Months Ended
	June 30,								June 30,
	2014			2013			Change		2014			2013			Change
Cost of Sales	$	35,902		$	43,756		(17.9	)%	$	66,499		$	90,062		(26.2	)%
Amortization of Purchased Technology	2,055			2,218			(7.3	)	4,109			4,435			(7.4	)
Total Cost of Sales	$	37,957		$	45,974		(17.4	)	$	70,608		$	94,497		(25.3	)
Gross Margin	24.0		%	29.7		%	(19.2	)%	24.7		%	29.3		%	(15.7	)%

Gross margin as a percentage of revenues decreased 570 bps for the three months ended June 30, 2014 from the comparable period in 2013. Unfavorable sales mix, which was driven by decreased sales in our higher margin Software-Solutions product group, was responsible for approximately 320 bps of the decrease. Additionally, the decrease in overall revenue levels absorbed a lower percentage of our fixed costs, which was responsible for the remaining 180 bps of the decrease.

Gross margin as a percentage of revenues decreased 460 bps for the six months ended June 30, 2014 from the comparable periods in 2013. This was the result of declined revenue across all product groups which represented 190 bps of the change. Lower revenue levels absorbing a lower percentage of our fixed costs were responsible for 280 bps of the change. These decreases were offset by a $1.4 million gain resulting in a 150 bps increase from a vendor claim on faulty components recorded in cost of sales during the first quarter of 2014.

Operating Expenses

The following table summarizes our operating expenses for the three and six months ended June 30, 2014 and 2013 (in thousands):

	Three Months Ended			Six Months Ended
	June 30,			June 30,
	2014	2013	Change	2014	2013	Change
Research and development	$8,408	$12,020	(30.0)%	$16,827	$23,555	(28.6)%
Selling, general and administrative	8,953	9,527	(6.0)	18,549	20,623	(10.1)
Intangible asset amortization	1,260	1,304	(3.4)	2,557	2,608	(2.0)
Restructuring and other charges, net	815	(114)	814.9	2,115	1,156	83.0
Total	$19,436	$22,737	(14.5)%	$40,048	$47,942	(16.5)%

Research and Development

R&D expenses consist primarily of product development costs, related equipment expenses and salary, bonuses and benefits for R&D personnel. R&D expenses decreased $3.6 million and $6.7 million for the three and six months ended June 30, 2014 from the comparable periods in 2013. The expense decrease is attributable to our second half 2013 restructuring efforts including our Shanghai and Penang site closures that enabled reductions in salary, overhead and other expenses. R&D headcount decreased year over year at June 30, 2014 from 459 to 411.

Selling, General, and Administrative

SG&A expenses consist primarily of salary, commissions, bonuses and benefits for sales, marketing and administrative personnel, as well as professional service providers and the costs of other general corporate activities. SG&A expenses decreased $0.5 million and $2.1 million for the three and six months ended June 30, 2014 from the comparable periods in 2013. Restructuring efforts in the second half of 2013 drove headcount reductions and contributed to a decrease in salary expense of $0.7 million and $1.1 million for the three and six months ended June 30, 2014 from the comparable periods in 2013. SG&A headcount decreased year over year at June 30, 2014 from to 197 to 170. Additionally, commission expense decreased $0.3 million and $0.8 million for the three and six months ended June 30, 2014 from the comparable periods in 2013 as a result of lower sales as our commission plan is weighted towards revenue-based incentives.

24

Intangible Asset Amortization

Intangible asset amortization for the three and six months ended June 30, 2014 was comparable with the same periods in 2013 due to routine amortization of acquired intangible assets.

Restructuring and Other Charges, Net

Restructuring and other charges, net includes expenses associated with restructuring activities and other non-recurring gains and losses.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.

The increase in restructuring and other charges, net for the three and six months ended June 30, 2014 from the comparable periods in 2013 is primarily due to restructuring actions associated with our Shanghai and Penang development site closures.

Restructuring and other charges, net for the three months ended June 30, 2014 include the following:

• $0.4 million net expense relating to the severance of employees in connection with the previously reported Penang site closure, as well as severance for two additional employees, net of reductions resulting from changes in previously estimated amounts for employee severance and associated payroll costs;

• $0.5 million integration-related net expense principally associated with asset disposals and personnel overlap resulting from resource consolidation primarily associated with our Penang site closure; and

• $0.1 million gain due to the decrease in fair value of the Continuous Computing contingent consideration liability. We assess the fair value of the contingent consideration liability on a quarterly basis, adjusting the liability to fair value based on a detailed analysis of all expected contingent consideration eligible revenues.

Restructuring and other charges for the three months ended June 30, 2013 include the following:

• $0.2 million gain resulting from forgiveness of remaining contractual payments due to our cancelled Security Gateway ("SEG") program partner;

• $0.6 million gain due to the decrease in fair value of the Continuous Computing contingent consideration liability; and

• $0.6 million net expense for severance and benefits associated with employee restructuring actions.

Restructuring and other charges, net for the six months ended June 30, 2014 include the following:

• $1.3 million net expense relating to the severance of employees in connection with the previously reported Penang site closure, as well as severance for 14 additional employees, net of reductions resulting from changes in previously estimated amounts for employee severance and associated payroll costs;

• $1.0 million integrated-related net expense principally associated with asset disposals and personnel overlap resulting from resource consolidation primarily associated with our Penang site closure; and

• $0.1 million gain due to the decrease in fair value of the Continuous Computing contingent consideration liability.

Restructuring and other charges, net for the six months ended June 30, 2013 include the following:

• $2.9 million write off of our SEG purchased technology asset due to management's decision to abandon future development of this technology;

• $1.5 million net gain from the sale of our OS-9 software assets;

• $1.3 million gain due to the decrease in fair value of the Continuous Computing contingent consideration liability; and

• $1.2 million net expense for the severance and benefits associated with employee restructuring actions.

Stock-based Compensation Expense

Included within cost of sales, R&D and SG&A are stock-based compensation expenses that consists of amortization of unvested stock options, restricted stock units and employee stock purchase plan ("ESPP") expense. We incurred and recognized stock-based compensation expense as follows (in thousands):

25

	Three Months Ended						Six Months Ended
	June 30,						June 30,
	2014		2013		Change		2014		2013		Change
Cost of sales	$	151	$	111	36.0	%	$	282	$	241	17.0	%
Research and development	324		234		38.5		553		483		14.5
Selling, general and administrative	985		678		45.3		1,746		1,398		24.9
Total	$	1,460	$	1,023	42.7	%	$	2,581	$	2,122	21.6	%

Stock-based compensation expense increased $0.4 million and $0.5 million for the three and six months ended June 30, 2014 from the comparable periods in 2013 due to increases in LTIP expense. This change was primarily driven by an increase in the Company's stock price on the LTIP award measurement date for the respective tranche in the current year as compared to the prior year.

Non-Operating Expenses

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

	Three Months Ended								Six Months Ended
	June 30,								June 30,
	2014			2013			Change		2014			2013			Change
Interest expense	$	(345	)	$	(281	)	22.8	%	$	(632	)	$	(613	)	3.1	%
Interest income	1			12			(91.7	)	10			23			(56.5	)
Other income, net	156			214			(27.1	)	326			350			(6.9	)
Total	$	(188	)	$	(55	)	241.8	%	$	(296	)	$	(240	)	23.3	%

Interest Expense

Interest expense includes interest incurred on our convertible senior notes and our revolving line of credit. The increase in interest expense during the three and six months ended June 30, 2014 from the comparable periods in 2013 is the result of

higher interest rates associated with our line of credit which was amended and restated in March 2014. The interest rate on the line of credit was 4.0% at June 30, 2014 and 2.19% at June 30, 2013.

Other Income, Net

For the three months ended June 30, 2014, other income decreased $0.1 million from the comparable periods in 2013 due to unfavorable currency movements against the US Dollar. For the six months ended June 30, 2014, other income was comparable to the same period in 2013.

Income Tax Provision

The following table summarizes our income tax provision (in thousands):

	Three Months Ended						Six Months Ended
	June 30,						June 30,
	2014		2013		Change		2014		2013		Change
Income tax expense	$	594	$	784	(24.2	)%	$	1,456	$	1,606	(9.3	)%

We recorded tax expense of $0.6 million and 1.5 million for the three and six months ended June 30, 2014. Our effective tax rates for the three months ended June 30, 2014 and 2013 were 7.8% and 23.6%. The effective tax rate fluctuation is mainly due to income tax rate differences among the jurisdictions in which pretax income (loss) is generated as well as the impact of valuation allowances against our U.S. and Canadian net deferred tax assets.

Cash Flows

As of June 30, 2014, the amount of cash held by our foreign subsidiaries was $9.0 million. It is not our intent to permanently reinvest funds in certain of our foreign entities, and we expect 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.

Cash and cash equivalents increased by $9.1 million to $34.6 million as of June 30, 2014 from $25.5 million as of December 31, 2013. Activities impacting cash and cash equivalents were as follows (in thousands):

	Six Months Ended
	June 30,
	2014			2013
Operating Activities
Net loss	$	(18,645	)	$	(10,669	)

Effects of exchange rate changes	4			(146		)
Net increase in cash and cash equivalents	$	9,124		$	744

Cash used in operating activities during the six months ended June 30, 2014 was $5.3 million. For the six months ended June 30, 2014, primary impacts to changes in our working capital consisted of the following:

• Other receivables increased $7.1 million as the result of the transfer of inventory to our new contract manufacturer for which we expect to be reimbursed during the third quarter of 2014;

• Inventory decreased by $4.3 million due to the sale of consigned inventory held at our current contract manufacturing partner to our new contract manufacturer; and

• Deferred revenue increased $4.3 million due primarily to MRF product shipments that have not met revenue recognition criteria.

Cash used in investing activities during the six months ended June 30, 2014 of $1.3 million was associated with capital expenditures.

Cash generated by financing activities during the six months ended June 30, 2014 of $15.7 million is attributable to $20.6 million of cash generated from the issuance of 6.6 million newly issued shares of our common stock. This addition was offset by $5.0 million of cash repayments of our Silicon Valley Bank line of credit.

Line of Credit

27

Silicon Valley Bank

At the beginning of the first quarter of 2014, we had a $35.0 million secured revolving line of credit agreement (as amended, the "Agreement") with Silicon Valley Bank ("SVB") with a stated maturity date of July 28, 2016. On March 14, 2014, we entered into an amended and restated $25.0 million secured revolving line of credit agreement (as amended, the "2014 Agreement") with SVB that replaces the Agreement and has a stated maturity date of July 28, 2016. On May 30, 2014 the 2014 Agreement was amended to increase the letter of credit sublimit under the secured revolving credit facility from $1,000,000 to $2,000,000. The secured revolving credit facility under the 2014 Agreement is available for cash borrowings and is subject to a borrowing formula based upon eligible accounts receivable less outstanding letters of credit (aggregate letters of credit are not to exceed $2,000,000). Eligible accounts receivable include 80% of U.S and 65% of foreign accounts receivable (80% in certain cases), not greater than 60 days past original invoice date. The interest rate is dependent upon the Company's Liquidity (as defined in the 2014 Agreement) when compared to a pre-determined threshold (the "Liquidity Threshold"), which is defined in the 2014 Agreement as $15.0 million, with the exception of the last month end of each quarter, where it is defined as $20.0 million. Liquidity is calculated under the 2014 Agreement as unrestricted cash plus unused availability on the revolving line of credit; however if the 2015 convertible senior notes are not renewed or refinanced 120 days prior to their maturity date, which is February 15, 2015, Liquidity (for purposes of testing against the Liquidity Threshold) will be reduced by the outstanding principal amount of the 2015 convertible senior notes. The calculation of interest under the 2014 Agreement is as follows:

• When Liquidity is above the Liquidity Threshold, the interest rate is the prime rate (as published in Wall Street Journal) plus 0.75%; and

• When Liquidity is below the Liquidity Threshold, the interest rate is the prime rate (as published in Wall Street Journal) plus 2.25%.

Under the 2014 Agreement, we are required to make interest payments monthly. We were further required to pay a loan modification fee of $35,000 and will be required to pay a commitment fee equal to $35,000 on July 29, 2014 and annually thereafter. Under the 2014 Agreement we are required to pay the higher of actual monthly interest incurred or the interest equivalent of $10.0 million in average monthly borrowings. If we terminate the commitment under the 2014 Agreement prior to the maturity date, we are required to pay a cancellation fee equal to 1.5% of the commitment under the 2014 Agreement.

The 2014 Agreement requires us to make certain representations, warranties and other agreements that are customary in credit agreements of this type. The 2014 Agreement also includes a financial covenant that requires us to maintain minimum Liquidity of $10.0 million tested monthly.

As of June 30, 2014 and December 31, 2013, we had outstanding balances of $10.0 million and $15.0 million under the 2014 Agreement and the Agreement, respectively. At June 30, 2014, we had $14.0 million of total borrowing availability remaining under the Agreement.

On July 9, 2014, we entered into a letter agreement (the "letter agreement") with SVB relating to the amended and restated $25.0 million secured revolving line of credit. The 2014 Agreement includes an Operating Accounts covenant stating that the Company and its subsidiaries may hold no more than $8.0 million in accounts maintained at financial institutions outside of the United States through August 31, 2014. As of June 30, 2014, the amount of cash held by the Company and its subsidiaries in accounts maintained at financial institutions outside of the United States was $9.0 million. Pursuant to the terms of the letter agreement, we obtained a waiver from SVB of the requirement to comply with the Operating Accounts covenant. After giving effect to the waiver, the Company was in compliance with all covenants under the 2014 Agreement.

2013 Convertible Senior Notes

On February 15, 2013, we repaid at maturity the entire $16.9 million outstanding balance of the 2.75% convertible senior notes due 2013 (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 and have a coupon rate of 4.5%. 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

28

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 any 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 June 30, 2014 and December 31, 2013, we had outstanding 2015 convertible senior notes with a face value of $18.0 million. As of June 30, 2014 and December 31, 2013, the fair values of our 2015 convertible senior notes were $17.9 million and $17.8 million, which are based on the most recent quoted prices of our publicly traded debt on each balance sheet date.

Contractual Obligations

Our contractual obligations as of December 31, 2013 are summarized in Item 7 - "Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources - Contractual Obligations," of the Company's Annual Report on Form 10-K for the year ended December 31, 2013. For the six months ended June 30, 2014, there have been no material changes in our contractual obligations outside the ordinary course of business. As of June 30, 2014, we have agreements regarding foreign currency forward contracts with total contractual values of $9.0 million that mature through 2015.

In addition to the above, we have approximately $3.9 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 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.

Liquidity Outlook

AtJune 30, 2014, our cash and cash equivalents amounted to $34.6 million. We believe that our current cash and cash equivalents combined with the remaining credit available under our line of credit facility will satisfy our expected short and long-term working capital, capital expenditures, and other liquidity requirements associated with our existing business operations and the repayment of the 2015 convertible senior notes. In the second quarter of 2014 we paid down the outstanding balance under the 2014 Agreement with SVB by $5.0 million, resulting in an outstanding balance of $10.0 million at quarter end. We anticipate maintaining covenant compliance throughout the duration of our anticipated borrowing, ensuring our current borrowing level and available borrowing capacity remains available to us.

Critical Accounting Policies and Estimates

We reaffirm our critical accounting policies and use of estimates as reported in our Annual Report on Form 10-K for the year ended December 31, 2013. There have been no significant changes during the three months ended June 30, 2014 to the items that we disclosed as our critical accounting policies and estimates in Management's Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report on Form 10-K for the year ended December 31, 2013.

All statements that relate to future events or to our future performance are forward-looking statements. In some cases, forward-looking statements can be identified by terms such as “may,” “will,” “should,” “expect,” “plans,” “seeks,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” “continue,” “seek to continue,” “consider,” “intends,” or other comparable terminology. These forward-looking statements are made pursuant to safe-harbor provisions of the Private Securities Litigation Reform Act of 1995. These forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause our actual results or our industries’ actual results, levels of activity, performance or achievements to be materially different from any future results, levels of activity, performance or achievements expressed or implied by these forward-looking statements.

These factors include, among others, the Company's high degree of customer concentration, the use of a single contract manufacturer for a significant portion of the production of our products, as well as the success of transitioning contract manufacturing partners, key employee attrition, the anticipated amount and timing of revenues from design wins and product orders due to the Company's customers' product development schedule, cancellations or delays, market conditions, matters affecting the embedded system industry, including changes in industry standards, changes in customer requirements and new product introductions, currency exchange rate fluctuations, changes in tariff and trade policies and other risks associated with foreign operations, actions by regulatory authorities or other third parties, the Company's ability to successfully manage the transition from 10G to 40G ATCA product technologies, cash generation, the Company's ability to successfully complete any restructuring, acquisition or divestiture activities and other factors described in "Risk Factors" and elsewhere in our Annual Report on Form 10-K for the year ended December 31, 2013, as updated in the subsequent quarterly reports on Form 10-Q. Although forward-looking statements help provide additional information about us, investors should keep in mind that forward-looking statements are only predictions, at a point in time, and are inherently less reliable than historical information.

We do not guarantee future results, levels of activity, performance or achievements, and we do not assume responsibility for the accuracy and completeness of these statements. The forward-looking statements contained in this report are made and based on information as of the date of this report. We assume no obligation to update any of these statements based on information after the date of this report.

Item 3. 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, 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 rate, and as of June 30, 2014 the total notional or contractual value of the contracts we held was $9.0 million. These contracts will mature over the next 14 months.

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 $0.9 million, reversing our Indian Rupee hedge asset as of June 30, 2014, to a liability of $0.2 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 $0.9 million, increasing our hedge asset as of June 30, 2014 to $1.6 million. We do not expect a 10% fluctuation to have any material 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 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 2015 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 values of the 2015 convertible senior notes due to the value of the notes derived from the conversion feature. Unless we elect to repurchase our 2015 convertible senior notes in the open market, changes in the fair value of the 2015 convertible senior notes have no impact on our cash flows or consolidated financial statements. The estimated fair value of the 2015 convertible senior notes were $17.9 million and $17.8 million at June 30, 2014 and December 31, 2013.

Item 4. Controls and Procedures

Based on their evaluation as of the end of the period covered by this Quarterly Report on Form 10-Q, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that the Company’s “disclosure controls and procedures” (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) are effective.

During our most recent fiscal quarter ended June 30, 2014, no change occurred in the Company's "internal control over financial reporting" (as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934) that has materially affected, or is reasonably likely to materially affect, the Company's internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1A. Risk Factors

There are many factors that affect our business and the results of our operations, many of which are beyond our control. In addition to the other information set forth in this report, you should carefully consider the factors discussed in Part I, Item 1A. Risk Factors and Part II, Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report on Form 10-K for the year endedDecember 31, 2013, which could materially affect our business, financial condition or future results. The risks described in this report and our Annual Report on Form 10-K for the year endedDecember 31, 2013are 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.

Item 5. Other Information

On July 9, 2014, the Company entered into a letter agreement (the “letter agreement”) with Silicon Valley Bank (“SVB”) relating to the Company’s amended and restated $25.0 million secured revolving line of credit (the “2014 Agreement”). The 2014 Agreement includes an Operating Accounts covenant stating that the Company and its subsidiaries may hold no more than $8.0 million in accounts maintained at financial institutions outside of the United States through August 31, 2014. As of June 30, 2014, the amount of cash held by the Company and its subsidiaries in accounts maintained at financial institutions outside of the United States was $9.0 million.

Pursuant to the terms of the letter agreement, the Company obtained a waiver from SVB of the requirement to comply with the Operating Accounts covenant. After giving effect to the waiver, the Company was in compliance with all covenants under the 2014 Agreement as of June 30, 2014.

Dear Jon:

This letter is written in connection with that certain Third Amended and Restated Loan and Security Agreement, by and between, Radisys Corporation ("Borrower") and Silicon Valley Bank ("Bank"), dated March 14, 2014 and related loan documents, as may be amended from time to time (the "Loan Agreement"). Borrower is in default of the Operating Accounts covenant as set forth in Section 6.8 of the Loan Agreement for the month ended June 2014.

Bank hereby waivers Borrower's existing default under the Loan Agreement by virtue of Borrower's failure to comply with the foregoing provision. Notwithstanding the waiver described above, Borrower shall be required to be in compliance with the Operating Accounts covenant for the month ended July 2014 and at all times thereafter pursuant to the terms of the Loan Agreement.

Bank's agreement to waiver the above-described default (1) in no way shall be deemed an agreement by the Bank to waiver Borrower's compliance with the above-described covenant as of all other dates and (2) shall not limit or impair the Bank's right to demand strict performance of this covenant as of all other dates and (3) shall not limit or impair the Bank's right to demand strict performance of all other covenants as of any date.

By signing below and returning a copy of this letter to Bank, Borrower acknowledges that the Loan Agreement has not been amended in any way. In entering into this letter, Bank is relying upon Borrower's representations, warranties, and agreements, as set forth in the Loan Agreement. Except as expressly provided for herein pursuant to this letter, the terms of the Loan Agreement remain unchanged and in full force and effect. Bank's agreement to modify the Loan Agreement in accordance with the provisions set forth in this letter in no way shall obligate Bank to make any future waivers or modifications to the Loan Agreement. Nothing in this letter shall constitute a satisfaction of the Borrower's indebtedness to Bank. It is the intention of Bank and Borrower to retain as liable parties all makers and endorsers of the Loan Agreement, unless the party is expressly released by Bank in writing. No maker or endorser will be released by virtue of this letter. The terms of this paragraph apply not only to this letter, but also to all subsequent loan modification agreements.

The provisions of this letter shall not be deemed effective until such time as Borrower shall have returned a countersigned copy to Bank.

Very truly yours,

BANK:

Assets and Liabilities Measured at Fair Value on a Recurring Basis

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 and deferred compensation liability are 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 Corporation ("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 increase or decrease accordingly in amounts that will vary based on the timing of the projected revenues and the timing of the expected payments.

The following table summarizes the fair value measurements for the Company's financial instruments (in thousands):

[4] under the Long-Term Incentive Plan ("LTIP") are presented 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 Company's Compensation and Development Committee. 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 the end of each semi-annual performance period. The maximum multiplier for a given semi-annual performance period is 2.75x the original grant and overall achievement is limited to a maximum of 2.5x of the target award over the entire performance period. Based on this formula, the maximum number of shares that could be earned was 0.8 million and 2.0 million for the three months ended June 30, 2014 and 2013

Significant Accounting Policies

Significant Accounting Policies

Radisys Corporation (the “Company” or “Radisys”) has adhered to the accounting policies set forth in its Annual Report on Form 10-K for the year ended December 31, 2013 in preparing the accompanying interim condensed consolidated financial statements. The preparation of these statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosure of contingent assets and liabilities. Actual results could differ from those estimates. Additionally, the accompanying financial data as of June 30, 2014 and for the three and six months ended June 30, 2014 and 2013 has been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2013.

Certain prior year balances have been reclassified to conform to the current year’s presentation. Such reclassifications did not affect total cash flows, total net revenues, operating loss, net loss, total assets, total liabilities or shareholders’ equity.

The financial information included herein reflects all normal recurring adjustments that are, in the opinion of management, necessary for a fair presentation of the results for interim periods.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments and Hedging Activities Disclosure [Text Block]

Hedging

The Company’s 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 June 30, 2014 and December 31, 2013, the only hedge instruments executed by the Company are associated with its exposure to fluctuations in the Indian Rupee, which result from obligations such as payroll and rent paid in this currency.

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 (loss) until the underlying hedged transaction affects net income (loss), at which time the gain (loss) will be reclassified out of accumulated other comprehensive income (loss) and recorded to the expense line item being hedged. The Company only enters into derivative contracts in order to hedge foreign currency exposure, and these 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 three and six months ended June 30, 2014 and 2013 and for the year ended December 31, 2013, the Company had no hedge ineffectiveness.

During the three months ended June 30, 2014 and 2013 and for the six months ended June 30, 2014, the Company did not enter into any new hedging contracts. During the six months ended 2013, the Company entered into 12 new foreign currency forward contracts with total notional contractual values of $2.5 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 June 30, 2014 is as follows (in thousands):

	Contractual/ Notional Amount		Condensed Consolidated Balance Sheet Classification	Estimated Fair Value
Type of Cash Flow Hedge				Asset		(Liability)
Foreign currency forward exchange contracts	$	8,966	Other current assets	$	662	$	—

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, 2013 is as follows (in thousands):

Ending balance of unrealized loss on forward exchange contracts	$	(268	)	$	(1,413	)	$	(268	)	$	(1,413	)

Over the next twelve months, the Company expects to reclassify into earnings a gain of approximately $0.1 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.

Short-term Debt

Short-Term Borrowings

Silicon Valley Bank

At the beginning of the first quarter of 2014, the Company had a $35.0 million secured revolving line of credit agreement (as amended, the "Agreement") with Silicon Valley Bank ("SVB") with a stated maturity date of July 28, 2016. On March 14, 2014, the Company entered into an amended and restated $25.0 million revolving line of credit agreement with SVB (as amended, the "2014 Agreement") that replaces the Agreement and has a stated maturity date of July 28, 2016. On May 30, 2014 the 2014 Agreement was amended to increase the letter of credit sublimit under the secured revolving credit facility from $1,000,000 to $2,000,000. The secured revolving credit facility under the 2014 Agreement is available for cash borrowings and is subject to a borrowing formula based upon eligible accounts receivable less outstanding letters of credit (aggregate letters of credit are not to exceed $2,000,000). Eligible accounts receivable include 80% of U.S. and 65% of foreign accounts receivable (80% in certain cases), not greater than 60 days past original invoice date. The interest rate is dependent upon the Company's Liquidity (as defined in the 2014 Agreement) when compared to a pre-determined threshold (the "Liquidity Threshold"), which is defined in the 2014 Agreement as $15.0 million, with the exception of the last month end of each quarter, where it is defined as $20.0 million. Liquidity is calculated under the 2014 Agreement as unrestricted cash plus unused availability on the revolving line of credit; however, if the Company's 4.50% convertible senior notes due 2015 (the "2015 convertible senior notes") are not renewed or refinanced 120 days prior to their maturity date, which is February 15, 2015, Liquidity (for purposes of testing against the Liquidity Threshold) will be reduced by the outstanding principal amount of the 2015 convertible senior notes. The calculation of interest under the 2014 Agreement is as follows:

• When Liquidity is above the Liquidity Threshold, the interest rate is the prime rate (as published in Wall Street Journal) plus 0.75%; and

• When Liquidity is below the Liquidity Threshold, the interest rate is the prime rate (as published in Wall Street Journal) plus 2.25%.

Under the 2014 Agreement, the Company is required to make interest payments monthly. The Company was further required to pay a loan modification fee of $35,000 and will be required to pay a commitment fee equal to $35,000 on July 29, 2014 and annually thereafter. Under the 2014 Agreement the Company is required to pay the higher of actual monthly interest incurred or the interest equivalent of $10.0 million in average monthly borrowings. If the Company terminates the commitment under the 2014 Agreement prior to the maturity date, the Company is required to pay a cancellation fee equal to 1.5% of the commitment under the 2014 Agreement.

The 2014 Agreement requires the Company to make certain representations, warranties and other agreements that are customary in credit agreements of this type. The 2014 Agreement also includes a financial covenant that requires the Company to maintain minimum Liquidity of $10.0 million tested monthly.

As of June 30, 2014 and December 31, 2013, the Company had outstanding balances of $10.0 million and $15.0 million under the 2014 Agreement and the Agreement, respectively. At June 30, 2014, the Company had $14.0 million of total borrowing availability remaining under the 2014 Agreement.

On July 9, 2014, the Company entered into a letter agreement (the "letter agreement") with SVB relating to the Company's amended and restated $25.0 million secured revolving line of credit. The 2014 Agreement includes an Operating Accounts covenant stating that the Company and its subsidiaries may hold no more than $8.0 million in accounts maintained at financial institutions outside of the United States through August 31, 2014. As of June 30, 2014, the amount of cash held by the Company and its subsidiaries in accounts maintained at financial institutions outside of the United States was $9.0 million. Pursuant to the terms of the letter agreement, the Company obtained a waiver from SVB of the requirement to comply with the Operating Accounts covenant. After giving effect to the waiver, the Company was in compliance with all covenants under the 2014 Agreement.

(A) For the three months ended June 30, 2014 there were no remaining contingently issuable shares outstanding. For the six months ended June 30, 2013, 30,000 contingently issuable shares were excluded from the calculation as their effect would have been anti-dilutive.

(B) For each of the three months ended June 30, 2014 and 2013, 2.1 million as-if converted shares associated with the Company's convertible senior notes were excluded from the calculation as their effect would have been anti-dilutive. For the six months ended June 30, 2014 and 2013, 2.1 million and 2.4 million as-if converted shares associated with the Company's convertible senior notes were excluded from the calculation as their effect would have been anti-dilutive.

(D) Shares under the Long-Term Incentive Plan ("LTIP") are presented 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 Company's Compensation and Development Committee. 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 the end of each semi-annual performance period. The maximum multiplier for a given semi-annual performance period is 2.75x the original grant and overall achievement is limited to a maximum of 2.5x of the target award over the entire performance period. Based on this formula, the maximum number of shares that could be earned was 0.8 million and 2.0 million for the three months ended June 30, 2014 and 2013.

2013 Convertible Senior Notes

On February 15, 2013, the Company repaid at maturity the entire outstanding balance of the 2.75% convertible senior notes due 2013 (the "2013 convertible senior notes") 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 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 June 30, 2014 and December 31, 2013, the Company had outstanding 2015 convertible senior notes with a face value of $18.0 million. As of June 30, 2014 and December 31, 2013, the fair values of our 2015 convertible senior notes were $17.9 million and $17.8 million, which are based on the most recent quoted prices of the Company's publicly traded debt on each balance sheet date.

The following table outlines the effective interest rate, contractually stated interest costs, and costs related to the amortization of issuance costs for the Company's 2013 and 2015 convertible senior notes:

Commitments and Contingencies

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 presented in other accrued liabilities in the accompanying Condensed 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 sales. If and when the Company takes possession of inventory reserved for in this liability, the liability is transferred from other accrued liabilities to the excess and obsolete inventory valuation allowance (Note 4 —Inventories).

In November 2013, the Company notified its existing contract manufacturer of the Company's intent to transition manufacturing to another contract manufacturer co-located with the Company's Shenzhen site. Upon notification of intent to terminate the relationship, the manufacturing agreement contractually obligates the Company to purchase all inventories in excess of ninety days demand. As of June 30, 2014 the existing contract manufacturer had yet to invoke this clause and therefore an inventory deposit and offsetting liability have not been reflected on the Condensed Consolidated Balance Sheets. The value of the potential liability in excess of the current adverse purchase commitment was $4.4 million at June 30, 2014.

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 an 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 June 30, 2014.

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 the 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):

	Six Months Ended
	June 30,
	2014			2013
Warranty liability balance, beginning of the period	$	3,328		$	3,954

Utilization of accrual	(1,604		)	(2,183		)
Warranty liability balance, end of the period	$	2,943		$	3,670

At June 30, 2014 and December 31, 2013, $2.3 million and $2.6 million of the warranty liability balance was included in other accrued liabilities and $0.6 million and $0.7 million was included in other long-term liabilities in the accompanying Condensed Consolidated Balance Sheets.

Income Tax Disclosure [Abstract]

Income Tax Disclosure

Income Taxes

The Company's effective tax rate for the three months ended June 30, 2014 differs from the statutory rate due to a full valuation allowance provided against its United States (“U.S.”) net deferred tax assets, a partial valuation allowance against Canadian deferred tax assets, and taxes on foreign income that differ from the U.S. tax rate. The Company’s effective tax rate for the three months ended June 30, 2013 differs from the statutory rate due the full valuation allowance provided against its U.S. net deferred tax assets, Canadian research and experimental development claims, and taxes on foreign income that differ from the U.S. tax rate.

The Company utilizes the asset and liability method of accounting for income taxes. The Company records deferred tax assets to the extent it believes these assets will more likely than not be realized. In making such determination, 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 upon the Company's review of all positive and negative evidence, including its three year U.S. cumulative pre-tax book loss and taxable loss, it concluded that a full and a partial valuation allowance should continue to be recorded against its U.S. and Canadian net deferred tax assets at June 30, 2014. In certain other foreign jurisdictions, where the Company does not have cumulative losses or other negative evidence, the Company had net deferred tax assets of $3.6 million and $3.8 million at June 30, 2014 and December 31, 2013. In the future, if the Company determines that it is more likely than not that it will realize its U.S. and Canadian net deferred tax assets, it will reverse the applicable portion of the valuation allowance and recognize an income tax benefit in the period in which such determination is made.

The Company's unrecognized tax benefits and related interest and penalties during the three months ended June 30, 2014 increased by $0.3 million primarily due to new uncertain tax exposures. The ending balance for the unrecognized tax benefits was approximately $3.9 million at June 30, 2014. The related interest and penalties were $0.5 million and $0.3 million. The uncertain tax positions that are reasonably possible to decrease in the next twelve months are insignificant.

The Company is currently under tax examination in India. The periods covered under examination are the Company's financial years 2005 through 2007 and 2009 through 2010. 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 June 30, 2014. As of June 30, 2014, the Company is not under examination by tax authorities in any other jurisdictions.

The LTIP provides for the grants of awards payable in shares of common stock upon the achievement of performance goals set by the Company's Compensation and Development Committee. 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 the end of each semi-annual performance period. The maximum multiplier for a given semi-annual performance period is 2.75x the original grant and overall achievement is limited to a maximum of 2.5x of the target award over the entire performance period. Based on this formula, the maximum number of shares that could be earned was 0.8 million and 2.0 million for the three months ended June 30, 2014 and 2013

Accounting Policies [Abstract]

Use of Estimates, Policy [Policy Text Block]

The preparation of these statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosure of contingent assets and liabilities. Actual results could differ from those estimates. Additionally, the accompanying financial data as of June 30, 2014 and for the three and six months ended June 30, 2014 and 2013 has been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading.
