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, 2016 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 March 31, 2017 and for the three months ended March 31, 2017 and 2016 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, 2016.

Certain changes in presentation have been made to conform prior presentations to the current year’s presentation in the condensed consolidated statement of cash flows within cash flows from operating activities.  In the current period, the Company combined charges to adverse purchase commitments (Note 7 - Commitments and Contingencies) and the inventory valuation allowance.  This resulted in reclassifications of $0.3 million for the three months ended March 31, 2016 within cash flows from operating activities.  Note 4 - Inventories includes a summary of charges associated with the valuation of inventory and the adverse purchase commitment liability. Such reclassifications did not affect total cash flows, cash flows from operations, 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.

Recent Accounting Pronouncements

In October 2016, the FASB issued Accounting standards Update No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory (''ASU 2016-16''). ASU 2016-16 modifies how intra-entity transfer of assets other than inventory are accounted for and presented in the financial statements. ASU 2016-16 is effective for public companies for annual reporting periods beginning after December 15, 2017. The Company adopted this ASU in the first quarter of 2017. The Company recognized a tax charge of approximately $2.0 million related to intra-entity transactions other than inventory which could not be previously recognized. The unrecognized tax charge is reflected as an adjustment to retained earnings.

In March 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Shared-Based Payment Accounting (''ASU 2016-09''). ASU 2016-09 simplifies how several aspects of share-based payments are accounted for and presented in the financial statements. ASU 2016-09 is effective for public companies for annual reporting periods beginning after December 15, 2016. The Company adopted this ASU in the first quarter of 2017. Upon adoption, the Company no longer uses a forfeiture rate in the calculation of stock based compensation expense. The impact of this election did not result in a significant charge to retained earnings from applying an estimated forfeiture rate in previous periods. The balance of the unrecognized excess tax benefits was reversed with the impact recorded to retained earnings and included changes to the valuation allowance as a result of the adoption. The Company has excess tax benefits for which a benefit could not be previously recognized of approximately $4.5 million. Due to the full valuation allowance on the U.S. deferred tax assets, there was no impact to the financial statements beyond disclosure as a result of this adoption.

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” ASU 2016-02 requires lessees to recognize a lease liability and a right-of-use asset on the balance sheet and aligns many of the underlying principles of the new lessor model with those in Accounting Standards Codification Topic 606, Revenue from Contracts with Customers. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the requirements of ASU 2016-02 and has not yet determined its impact on the condensed consolidated financial statements.

7

In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)," which is the new comprehensive revenue recognition standard that will supersede all existing revenue recognition guidance under U.S. GAAP. The standard's core principle is that a company will recognize revenue when it transfers promised goods or services to a customer in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. ASU 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date," which was issued in August 2015, revised the effective date for this ASU to annual and interim periods beginning on or after December 15, 2017, with early adoption permitted, but not earlier than the original effective date of annual and interim periods beginning on or after December 15, 2016, for public entities.

The new standard permits adoption either by using (i) a full retrospective approach for all periods presented in the period of adoption or (ii) a modified retrospective approach with the cumulative effect of initially applying the new standard recognized at the date of initial application and providing certain additional disclosures. The Company does not plan to early adopt this new standard, and accordingly, the Company will adopt the new standard effective January 1, 2018.

The Company currently plans to adopt using the modified retrospective approach. However, a decision regarding the adoption method has not been finalized at this time. The final determination will depend on a number of factors, such as the significance of the impact of the new standard on financial results, system readiness and the Company's ability to accumulate and analyze the information necessary to assess the impact on prior period financial statements, as necessary.

The Company's evaluation of the impact of the new standard on the Company's accounting policies, processes, and system requirements is ongoing. While the Company continues to assess all potential impacts under the new standard, the Company does not believe there will be significant changes to the timing of recognition of hardware sales, software license sales or service contracts.

As part of the Company's preliminary evaluation, the Company also considered the impact of the guidance in ASC 340-40, "Other Assets and Deferred Costs; Contracts with Customers". This guidance requires the capitalization of all incremental costs that we incur to obtain a contract with a customer that the Company would not have incurred if the contract had not been obtained, provided the Company expects to recover the costs. The Company preliminarily believes that there will not be significant changes to the timing of the recognition of sales commissions since the Company's commission plan is earned based on the recognition of revenue; however, there is a potential that the amortization period for commission costs may be longer than the contract term in some cases, as the new cost guidance requires entities to determine whether the costs relate to specific anticipated contracts as well.

While the Company continues to assess the potential impacts of the new standard, including the areas described above, the Company cannot reasonably estimate quantitative information related to the impact of the new standard on its financial statements at this time.

Immaterial Revision to Prior Period Financial Statement

The Company has revised the presentation of revenue and cost of sales to separately present those amounts that are associated with service and related activities from those amounts associated with product sales. This change does not impact the Company’s previously reported total revenues, gross margin, loss from operations or net loss for the periods presented.

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

8

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

	Fair Value Measurements as of March 31, 2017
	Total		Level 1	Level 2		Level 3
Foreign currency forward contracts	$	846	—	$	846	—

	Fair Value Measurements as of December 31, 2016
	Total		Level 1	Level 2		Level 3
Foreign currency forward contracts	$	94	—	$	94	—

Note 3 — Accounts Receivable and Other Receivables

Accounts receivable consists of sales to the Company's customers which are generally based on standard terms and conditions. Accounts receivable balances consisted of the following (in thousands):

	March 31, 2017			December 31, 2016
Accounts receivable, gross	$	49,980		$	38,433
Less: allowance for doubtful accounts	(55		)	(55		)
Accounts receivable, net	$	49,925		$	38,378

As of March 31, 2017 and December 31, 2016, the balance in other receivables was $3.4 million and $4.2 million. Other receivables consisted primarily of non-trade receivables including inventory sold to the Company's contract manufacturing partner or other integration partners (on which the Company does not recognize revenue) and net receivables for value-added taxes.

Note 4 — Inventories

Inventories consisted of the following (in thousands):

	March 31, 2017			December 31, 2016
Raw materials	$	16,917		$	24,805
Work-in-process	—			12
Finished goods	3,924			5,005
	20,841			29,822
Less: inventory valuation allowance	(9,996		)	(9,801		)
Inventories, net	$	10,845		$	20,021

Consigned inventory is held at third-party locations, which include the Company's contract manufacturing partner and customers. The Company retains title to the inventory until purchased by the third-party. Consigned gross inventory, consisting of raw materials and finished goods was $11.6 million and $11.8 million at March 31, 2017 and December 31, 2016.

The Company’s consignment inventory with its contract manufacturer consists of inventory transferred from the Company’s prior contract manufacturer as well as inventory that has been purchased by the contract manufacturer as a result of the Company's forecasted demand. The Company was contractually obligated to purchase inventory transferred from the Company's prior contract manufacturer after the inventory ages for 365 days. All transferred inventory not consumed was repurchased by the Company in 2016. The Company is also contractually obligated to purchase inventory that has been

9

purchased by its contract manufacturer as a result of the Company's forecasted demand when the inventory ages beyond 180 days and has no forecasted demand. The Company’s consigned inventory at its contract manufacturing partner was $11.6 million and $11.8 million as of March 31, 2017 and December 31, 2016. The Company records a liability for adverse purchase commitments of inventory owned by its contract manufacturing partner. See Note 7 - Commitments and Contingencies for additional information regarding the Company's adverse purchase commitment liability.

The Company recorded the following charges associated with the valuation of inventory and the adverse purchase commitment liabilities (in thousands):

	Three Months Ended
	March 31,
	2017		2016
Inventory, net	$	501	$	266
Adverse purchase commitments(A)	201		279
Net charges	$	702	$	545

(A) When the Company takes possession of inventory reserved for under the adverse purchase liability (Note 7 — Commitments and Contingencies), the associated liability is transferred from other accrued liabilities to the excess and obsolete inventory valuation allowance.

Note 5 — Restructuring and Other Charges

The following table summarizes the Company's restructuring and other charges as presented in the Condensed Consolidated Statement of Operations (in thousands):

	Three Months Ended
	March 31,
	2017		2016
Employee-related restructuring expenses	$	42	$	682
Integration-related and other non-recurring expenses	193		—
Restructuring and other charges, net	$	235	$	682

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 March 31, 2017, the Company recorded the following restructuring charges:

• $0.1 million net expense relating to the severance for 2 employees in connection with a reduction to our hardware engineering presence in Shenzhen; and

• $0.2 million in non-recurring legal expenses associated with closing a strategic agreement with a MediaEngine channel partner.

For the three months ended March 31, 2016, the Company recorded the following restructuring and other charges:

• $0.7 million net expense relating to the severance for 21 employees primarily in connection with a reduction to our hardware engineering presence in Asia.

10

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

On September 19, 2016, the Company entered into a Credit Agreement (as amended, the “Credit Agreement”) with Silicon Valley Bank (“SVB”), as administrative agent, and the other lenders party thereto. The Credit Agreement replaces the Company’s Third Amended and Restated Loan and Security Agreement with SVB, dated March 14, 2014 (as amended, the “2014 Agreement”). On January 5, 2017, the Company entered into the First Amendment to the Credit Agreement. The following takes into account the terms per the agreement as amended on January 5, 2017.

The Credit Agreement provides for a revolving loan commitment of $55.0 million and has a stated maturity date of September 19, 2019. The Credit Agreement includes a $10.0 million sub-limit for swingline loans and a $10.0 million sub-limit for letters of credit. The Credit Agreement also includes an accordion feature that allows the Company, at any time, to increase the aggregate revolving loan commitments by up to an additional $25.0 million, subject to the satisfaction of certain conditions, including obtaining the lenders’ agreement to participate in the increase.

Borrowings under the Credit Agreement are subject to a borrowing base, which is a formula based upon certain eligible accounts receivable plus up to $7.5 million if the Company’s Liquidity (as defined in the Credit Agreement) is above $20.0 million in the first and second month of any fiscal quarter and $25.0 million for the last month of a fiscal quarter, measured as of the last day of the applicable month. Eligible accounts receivable include 85% of certain U.S. and 75% of certain foreign accounts receivable (85% in certain cases). The Credit Agreement also provides for non-formula advances during the last business day of any fiscal quarter, provided that Liquidity on the date of a requested non-formula advance must be greater than or equal to $40.0 million, the non-formula advance must be repaid on or before the first business day after the applicable fiscal quarter end, and subject to the satisfaction of certain other conditions.

Outstanding borrowings under the revolving loan commitment bear interest at a per annum rate based upon the Company's Availability (as defined in the Credit Agreement), which means the quotient of the amount available for borrowings under the Credit Agreement divided by the lesser of the total commitment and the borrowing base, calculated as a daily average over the immediately preceding fiscal month. The Credit Agreement provides that the per annum interest rate on or before March 31, 2017 and at any time thereafter when the Consolidated Adjusted EBITDA (as defined in the Credit Agreement) as measured on a trailing twelve-month basis for the immediately preceding fiscal quarter period is less than the Consolidated Adjusted EBITDA threshold as specified in the Credit Agreement will be as follows:

• When Availability is 70% or more, the interest rate is the prime rate (as published in Wall Street Journal) plus 0.50%;

• When Availability is 30% or more and less than 70%, the interest rate is the prime rate plus 0.75%; and

• When Availability is below 30%, the interest rate is the prime rate plus 1.00%.

11

After March 31, 2017, if Consolidated Adjusted EBITDA as measured on a trailing twelve-month basis for the immediately preceding fiscal quarter period is equal to or greater than the Consolidated Adjusted EBITDA threshold as specified in the Credit Agreement, the rate per annum will be as follows:

• When Availability is 70% or more, the interest rate is the prime rate plus 0.25%;

• When Availability is 30% or more and less than 70%, the interest rate is the prime rate plus 0.50%; and

• When Availability is below 30%, the interest rate is the prime rate plus 0.75%.

Under the Credit Agreement, the Company is required to make interest payments monthly. The Company is further required to pay $25,000 in annual administrative fees, $82,500 in annual commitment fees and a commitment fee based on the average unused portion of the revolving credit commitment, and certain other fees in connection with letters of credit. The commitment fee is determined as follows and is payable quarterly in arrears:

• When Availability is 70% or more, the commitment fee is 0.35% of the average unused portion of the revolving credit commitment;

• When Availability is 30% or more and less than 70%, the commitment fee is 0.325% of the average unused portion of the revolving credit commitment; and

• When Availability is below 30%, the commitment fee is 0.3% of the average unused portion of the revolving credit commitment.

The Company paid a total of $0.3 million loan origination fees which were capitalized and will be expensed over the term of the Credit Agreement. If the Company reduces or terminates the revolving loan commitment under the Credit Agreement prior to September 19, 2017, the Company is required to pay a cancellation fee equal to 0.75% of the total revolving loan commitment.

The Credit Agreement requires that the Company comply with financial covenants requiring the Company to maintain a minimum monthly Liquidity of $15.0 million as of the last day of the first and second month of any fiscal quarter and $20.0 million as of the last day of the third month of any fiscal quarter. Additionally, the Credit Agreement requires the Company to maintain a minimum trailing twelve months Consolidated Adjusted EBITDA each quarter of fiscal year 2017. The Credit Agreement also provides that following fiscal year 2017, SVB, as administrative agent, and the required lenders under the Credit Agreement will re-set the required minimum Consolidated Adjusted EBITDA levels for the periods tested in fiscal years 2018 and 2019.

All obligations under the 2016 Agreement are unconditionally guaranteed by the Company's wholly owned subsidiary, Radisys International LLC. The obligations under the Credit Agreement are secured by a first priority lien on the assets of the Company and the subsidiary guarantor. If the Company acquires or forms a material U.S. subsidiary, then that subsidiary will also be required to guarantee the obligations under the Credit Agreement and grant a first priority lien on its assets.

As of March 31, 2017 and December 31, 2016, the Company had an outstanding balance of $40.0 million and $25.0 million under the Credit Agreement. At March 31, 2017, the Company had $3.9 million of total borrowing availability remaining under the Credit Agreement. Under the First Amendment, the Company may borrow up to $55.0 million at fiscal quarter ends. The Company's gross borrowing availability was $43.9 million excluding the quarter end non-formula availability. At March 31, 2017, the Company was in compliance with all covenants under the Amended Agreement.

Note 7 — 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. 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 and Deferred Cost of Sales).

12

The adverse purchase commitment liability is included in other accrued liabilities in the accompanying Condensed Consolidated Balance Sheets and was $0.5 million and $0.3 million as of March 31, 2017 and December 31, 2016.

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 March 31, 2017.

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.

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 to 24 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):

	Three Months Ended
	March 31,
	2017			2016
Warranty liability balance, beginning of the period	$	1,821		$	2,553
Product warranty accruals	223			385
Utilization of accrual	(315		)	(603		)
Warranty liability balance, end of the period	$	1,729		$	2,335

At March 31, 2017 and December 31, 2016, $1.4 million and $1.5 million of the warranty liability balance was included in other accrued liabilities and $0.3 million and $0.4 million was included in other long-term liabilities in the accompanying Condensed Consolidated Balance Sheets.

(B) Performance based restricted stock units are presented based on attainment of 100% of the performance goals being met.

Note 9 — Income Taxes

The Company's effective tax rate for the three months ended March 31, 2017 differs from the statutory rate due to a full valuation allowance provided against its United States (“U.S.”) net deferred tax assets, 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 March 31, 2017. 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 $1.0 million and $1.1 million at March 31, 2017 and December 31, 2016. 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.

14

The ending balance for the unrecognized tax benefits for uncertain tax positions was approximately $3.5 million at March 31, 2017. The related interest and penalties were $0.8 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, 2006, 2008 and 2011. The examinations are 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 March 31, 2017. The Company is currently under tax examination in Canada. The periods covered under examination in Canada are the Company's financial years 2013 and 2014. No examination adjustments have been proposed. As of March 31, 2017, the Company is not under examination by tax authorities in any other jurisdictions.

Note 10 — Stock-based Compensation

The following table summarizes awards granted under the Radisys Corporation 2007 and LTIP Stock Plans (in thousands):

	Three Months Ended

Stock options	—	1,036
Restricted stock units	467	—
Performance based restricted stock awards (A)	670	680
Total	1,137	1,716

(A) On March 10, 2017, the Compensation Committee approved grants of performance-based restricted stock units ("PRSUs") to certain employees. The awards will vest only on satisfaction of certain performance criteria during two separate annual performance periods and a portion of the award earned will vest upon satisfaction of a time-based service component. 50% of the awards can be earned by meeting strategic revenue targets in fiscal year 2017 and 50% can be earned by meeting strategic revenue targets in fiscal year 2018. One-half of any PRSUs earned during each performance period will vest upon meeting the performance criteria, and the remaining half will be subject to a further time-based service component and will vest one year after meeting the targets. By meeting the relevant performance criteria set forth in the award agreement, employees can earn 0%, 75%, 100% or 125% of the award during each performance period.  If an employee earns less than 100% of the award for the 2017 performance period, the employee is eligible to earn the remaining portion of the award in fiscal year 2018 if cumulative 2017 and 2018 strategic revenue targets are met in the two year period.  Shares are presented based on attainment of 100% of the performance goals being met. At attainment of 125%, the amount of shares eligible to be earned is 837,500.

On March 28, 2016, the Compensation Committee approved grants of PRSUs to certain senior executives. The PRSUs will vest only on satisfaction of certain annual performance criteria during the performance period beginning on the grant date. Specifically, 50% of shares will vest on meeting targets of strategic revenue during fiscal year 2016 and 50% of shares will vest on meeting targets of strategic revenue during fiscal year 2017, subject to the attainment of achieving certain operating income thresholds defined by the Company's ratified 2017 annual operating plans. The awards have two separate annual performance achievement periods in 2016 and 2017 and vest upon attainment and approval of the respective performance conditions.

The awards associated with strategic revenue targets in 2016 were earned and settled in shares in the three month period ended March 31, 2017.

Note 11 — 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 March 31, 2017 and December 31, 2016, 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 (loss) is affected by the variability of the cash flows of the hedged transaction. Typically, hedge ineffectiveness could result when the amount of the Company’s hedge contracts exceed the Company’s forecasted or actual transactions for which the hedge contracts were designed to hedge. Once a hedge contract matures, the associated gain (loss) on the contract will remain in other comprehensive income (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 months ended March 31, 2017 and 2016, the Company had no hedge ineffectiveness.

During thethreemonths ended March 31, 2017 the Company entered into 6 new foreign currency forward contracts, with total contractual values of $3.6 million. During the three months ended March 31, 2016, the Company entered into 12 new foreign currency contracts, with total contractual values of $3.6 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 March 31, 2017 is as follows (in thousands):

	Contractual/ Notional Amount		Condensed Consolidated Balance Sheet Classification	Estimated Fair Value

Other comprehensive income (loss)	502			134
Ending balance of unrealized loss on forward exchange contracts	$	(25	)	$	(685	)

Over the next twelve months, the Company expects to reclassify into earnings income of approximately $0.4 million currently recorded as accumulated 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.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

You should read the following discussion and analysis in conjunction with our condensed consolidated financial statements and the related notes included in this Report on Form 10-Q and with Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. Unless required by context, or as otherwise indicated, “we,” “us,” “our” and similar terms, as well as references to the “Company” and “Radisys” refer to Radisys Corporation and include all of our consolidated subsidiaries.

Overview

Radisys Corporation (NASDAQ: RSYS), the services acceleration company, helps communications and content providers, and their strategic partners, create new revenue streams and drive cost out of their services delivery infrastructure. Radisys’ hyperscale software defined infrastructure, service aware traffic distribution platforms, real-time media processing engines and wireless access technologies enable its customers to maximize, virtualize and monetize their networks. Our products and services fall within two operating segments: Software-Systems and Hardware Solutions.

• Software-Systems products are targeted at delivering differentiated solutions for service providers to enable their deployment of next generation networks and technologies. Software-Systems products include the following three product families:

19

◦ FlowEngine products target the communication service provider traffic management market and is a family of products designed to rapidly classify millions of data flows and then distribute these flows to thousands of Virtualized Network Functions ("VNF"). FlowEngine offloads the processing for packet classification and distribution, improving virtualized function utilization and making the overall Network Functions Virtualization ("NFV") architecture more efficient. A FlowEngine system consists of FlowEngine software running on a Traffic Distribution Engine ("TDE") platform. FlowEngine Software enables communication service providers to efficiently transition towards NFV and software-defined networking ("SDN") architectures allowing increased service agility and quicker time to revenue for new service offerings. FlowEngine accomplishes this by integrating a targeted subset of edge routing, data center switching, and load balancing functionality, coupled with standards based SDN protocols, enabling our customers to significantly reduce the investment necessary to efficiently process data flows in virtualized communications environments.

◦ MediaEngine products are designed into the IP Multimedia Subsystem ("IMS") core of telecom networks, providing the necessary media processing capabilities required for a broad range of applications including Voice over Long-Term Evolution ("VoLTE"), Voice over WiFi (“VoWifi”), Web Real-Time Communication ("WebRTC"), multimedia conferencing, as well as the transcoding required to achieve interoperability between legacy and new generation devices using disparate audio and video codecs. Our MediaEngine OneMRF strategy helps service providers consolidate their real-time IP media processing into a vendor and application agnostic platform, which drives cost out of their service delivery platform and enables accelerated deployment and introduction of new services. We sell a turnkey high density system, the MediaEngine MPX-12000, as well as a virtualized software-only vMRF for customers who require media processing in an NFV architecture or lower-density processing platforms. As service providers consolidate network capacity from older (3G and 2G) architectures onto new LTE architectures, they will deploy IMS and VoLTE applications. Our MediaEngine provides the essential media processing capability that enables service providers to deliver audio, video or other multimedia services over their all-IP networks.

◦ CellEngine software provides the enabling technology for fifth generation radio access networks (“5G RAN”) and is optimized for spectrum utilization, densification and network slicing to serve multiple users for mobility, latency and capacity. This builds on CellEngine’s portfolio of existing solutions for Radio Access Networks (“RAN”) and Evolved Packet Core (“EPC”) for Long-Term Evolution (“LTE”), LTE-Advanced and LTE-Advanced pro. An emerging area of focus is the Internet of Things (“IoT”) market for lower power wireless area networks which are enabled by Category M1 (“Cat-M1”) and Narrowband IoT. CellEngine software is licensed to Original Equipment Manufacturers (“OEMS”), Original Design Manufacturers (“ODMs”) and operators who are building solutions for femtocells, small cells, metrocells, picocells as well as in-building, stadium and smart cities leveraging centralized RAN (“CRAN”). Additionally, we leverage our CellEngine technology to enable applications to capture share in adjacent markets such as aerospace and defense, public safety and test and measurement.

◦ Also included in this segment is our Professional Services organization that is staffed with telecommunications experts who are available to assist our customers as they develop their own unique telecommunications products and applications as well as accelerating specific features developed across our Software-Systems product families. Our strategy is to enable the efficient and cost-effective adoption of our Software-Systems products as well as enabling service providers to migrate to next-generation software-defined network deployments.

• Hardware Solutions leverages our hardware design experience, coupled with our manufacturing, supply chain, integration and service capabilities, to enable continued differentiation from our competition. Our products include the following two primary product families:

◦ DCEngine products include open-based rack-scale systems, utilizing Open Compute Project (“OCP") accepted specifications, which enable service providers to migrate their existing infrastructure to embrace the efficiencies and scale of data center environments. This recently launched product suite brings the economies of the data center and the agility of the cloud to service provider infrastructure, allowing them to accelerate the transformation to cloud based compute, storage and networking fabrics utilizing the best of commodity components, open source hardware specifications and software coupled with world class service and support. The DCEngine platform enables service providers to drive innovation and the rapid scalable delivery of virtualized network functions at the network edge, enabling new services such as storage backup, video on demand and parental controls.

20

◦ Embedded products which includes our ATCA, computer-on-module express (COM Express) and rack mount servers. These products are predominantly hardware-based and include both our internal designs as well as increasingly leveraging third party hardware which incorporates our management software and services capabilities. Our products enable the control and movement of data in both 3G and LTE telecom networks and provide the hardware enablement for network elements applications such as Deep Packet Inspection ("DPI"), policy management and intelligent gateways (security, femto and LTE gateways). Additionally, our products enable image processing capabilities for healthcare markets and enable cost-effective and energy-efficient computing capabilities dedicated for industrial deployments. Our professional service organization of systems architects, hardware designers, and network experts accelerates our customers' time to market on these revenue generating assets.

First Quarter 2017 Summary

As a result of our current customer concentration, the timing of large orders will vary from quarter-to-quarter and affect our quarterly comparisons, and given the spending patterns of these large customers, we do not expect year-on-year revenue growth every quarter. As a result, our near-term results will vary and may affect earnings when combined with the continued investment required to support the growing funnel of sales opportunities with potential and existing customers. These trends affected our first quarter of 2017 results as consolidated revenue decreased $17.5 million from the same quarter 2016. This was the result of inconsistent ordering patterns from two of our top customers as well as the continued decline in our legacy embedded products as a direct result of the strategic changes implemented early in 2015 to focus on key customers who have adequate scale to meet our profitability and cash flow objectives and as certain products within this product family trend to end-of-life.

The following is a summary-level comparison of the three months ended March 31, 2017 and 2016:

• Revenues decreased $17.5 million to $37.6 million for the three months ended March 31, 2017 from $55.1 million for the three months ended March 31, 2016. Hardware Solutions revenue decreased $13.6 million, due to a $5.8 million decline in revenue from our DCEngine product line that was the result of non-linear ordering patterns from a tier-one U.S. service provider. Additionally, non-core legacy product sales declined $7.8 million as certain legacy products trend towards end of life. Software-Systems revenue decreased by $3.9 million as the result of the timing of orders from two of our top customers.

• Gross margin percent declined 130 basis points to 21.9% for the three months ended March 31, 2017 from 23.2% for the three months ended March 31, 2016. The $17.5 million decrease in revenue described above absorbed less of the fixed $1.9 million of amortized purchased technology recognized in both periods resulting in a 160 basis decrease quarter over quarter. This was partially offset by improved standard gross margins given product mix as well as higher DCEngine product margins due to maturing manufacturing and integration processes.

• R&D expense increased by $0.8 million to $6.5 million for the three months ended March 31, 2017 from $5.7 million in 2016. This is the result of increased headcount and other product development expenses related to continued investment in our strategic product lines, including the introduction of our new FlowEngine appliance expected to be deployed in mid-2017.

• SG&A expense increased $1.7 million to $9.4 million for the three months ended March 31, 2017 from $7.6 million for the three months ended March 31, 2016. This is the result of headcount growth in sales and marketing as we have accelerated hiring to support our strategic product line growth initiatives.

• Cash and cash equivalents on March 31, 2017 decreased $1.1 million to $32.0 million from $33.1 million at December 31, 2016. The decrease was the result of $14.5 million cash consumption from operations which was the result of working capital timing due to fulfillment of DCEngine product orders that were shipped during the quarter and capital expenditures of $1.8 million. The consumption was partially offset by a $15.0 million net draw on our line of credit.

Revenues

The following table sets forth operating segment revenues for the three months ended March 31, 2017 and 2016 (in thousands):

	Three Months Ended
	March 31,
	2017		2016		Change
Revenue
Software-Systems	$	10,149	$	14,059	(27.8	)%
Hardware Solutions	27,461		41,087		(33.2	)
Total revenues	$	37,610	$	55,146	(31.8	)%

22

Software-Systems. Revenues in our Software-Systems segment declined $3.9 million for the three months ended March 31, 2017 from the comparable period in 2016. Revenue from two of our top MediaEngine customers declined by $3.3 million in the three months ended March 31, 2017 due to non-linear ordering patterns driven by the timing of network deployments. Additionally, FlowEngine product revenue declined $3.2 million as we transition from the TDE-500 to our new SDN-enabled appliance that is expected to be deployed in the second half of 2017. These declines were partially offset by a $1.7 million increase in professional services revenue as engagements with tier-one service providers continue to increase year-on-year.

Hardware Solutions. Revenues in our Hardware Solutions segment decreased $13.6 million for the three months ended March 31, 2017 from the comparable period in 2016. This is the result of a $5.8 million decline in DCEngine sales due to non-linear order patterns with our tier-one U.S. service provider in support of their initial data center build outs as well as expected declines of $7.8 million in non-core legacy hardware products.

Revenue by Geography

The following tables outline overall revenue dollars and the percentage of revenues, by geographic region, for the three months ended March 31, 2017 and 2016 (in thousands):

	Three Months Ended
	March 31,
	2017		2016		Change
North America	$	23,171	$	37,843	(38.8	)%
Asia Pacific	5,419		7,618		(28.9	)
Europe, the Middle East and Africa ("EMEA")	9,020		9,685		(6.9	)
Total	$	37,610	$	55,146	(31.8	)%

	Three Months Ended
	March 31,
	2017		2016
North America	61.6	%	68.6	%
Asia Pacific	14.4		13.8
EMEA	24.0		17.6
Total	100.0	%	100.0	%

North America. Revenues from North America decreased $14.7 million for the three months ended March 31, 2017 from the comparable period in 2016. This was due to an expected decline in sales to a tier-one U.S. service provider purchasing both DCEngine and FlowEngine products given the non-linear order patterns and timing of this service provider's deployment schedule.

Asia Pacific. Revenues from Asia Pacific declined $2.2 million for the three months ended March 31, 2017 from the comparable period in 2016. This was the result of fewer MediaEngine sales to a large Asian service provider in support of their VoLTE network deployment.

EMEA. Revenues from EMEA decreased $0.7 million for the three months ended March 31, 2017 from the comparable period in 2016. This resulted from a decrease in order quantities from a top five customer deploying our products in medical imaging and related markets.

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 sets forth operating segment gross margins for the three months ended March 31, 2017 and 2016 (in thousands):

	Three Months Ended
	March 31,
	2017			2016			Change
Gross margin
Software-Systems	$	5,465		$	8,788		(37.8	)%
Hardware Solutions	4,781			5,969			(19.9	)
Corporate and other	(2,024		)	(1,973		)	2.6
Total gross margin	$	8,222		$	12,784		(35.7	)%

	Three Months Ended
	March 31,
	2017		2016		Change
Gross margin
Software-Systems	53.8	%	62.5	%	(13.9	)%
Hardware Solutions	17.4		14.5		20.0
Corporate and other	—		—		—
Total gross margin	21.9	%	23.2	%	(5.6	)%

Software-Systems. Gross margin decreased 870 basis points to 53.8% for the three months March 31, 2017 from 62.5% in the comparable period in 2016. This was the result of unfavorable product mix of less software-rich MediaEngine and FlowEngine product sales in the current period and proportionately higher professional services which generally generates a comparably lower gross margin.

Hardware Solutions. Gross margin increased 290 basis points to 17.4% for the three months ended March 31, 2017 from 14.5% in the comparable period of 2016. The increase in margin was the result of improved gross margins on DCEngine products due to maturing manufacturing and integration processes.

Corporate and other. Gross margin was flat at a deficit of $2.0 million for the three months ended March 31, 2017 from the comparable period in 2016 related to a modest decline in intangible asset amortization as certain assets are now fully amortized. Items in Corporate and other cost of sales include amortization of intangible assets, stock compensation and restructuring and other expenses which are not allocated to our operating segments.

Operating Expenses

The following table summarizes our operating expenses for the three months ended March 31, 2017 and 2016 (in thousands):

	Three Months Ended
	March 31,
	2017		2016		Change
Research and development	$	6,480	$	5,653	14.6%
Selling, general and administrative	9,382		7,639		22.8
Intangible asset amortization	1,260		1,260		—
Restructuring and other charges, net	235		682		(65.5)
Total	$	17,357	$	15,234	13.9%

Research and Development

24

R&D expenses consist primarily of personnel costs, product development costs, and related equipment expenses. R&D expenses increased $0.8 million for the three months ended March 31, 2017 from the comparable period in 2016 primarily due to increases in salary and employee related expenses of $0.7 million and increases in product development-related expenses of $0.1 million. Headcount increased to 308 at March 31, 2017 from 301 at March 31, 2016.

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 increased $1.7 million for the three months ended March 31, 2017 from the comparable period in 2016 primarily due to increases in salary, stock compensation, and hiring-related expenses of $1.4 million, which is the result of additions to sales and marketing headcount in support of our strategic revenue growth initiatives. Headcount increased to 145 at March 31, 2017 from 114 at March 31, 2016.

Intangible Asset Amortization

Intangible asset amortization for the three months ended March 31, 2017 was comparable with the same period in 2016 due to routine amortization of acquired intangible assets. No triggering events occurred during the quarter ended March 31, 2017 that could potentially result in management performing an impairment evaluation of our 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 which are not indicative of our ongoing business operations.We evaluate the adequacy of the accrued restructuring charges on a quarterly basis. As a result, we record reversals to the accrued restructuring in the period in which we determine that expected restructuring and other obligations are less than the amounts accrued.

Restructuring and other charges, net decreased $0.4 million to $0.2 million for the three months ended March 31, 2017 from $0.7 million in the comparable period in 2016.

Restructuring and other charges, net for the three months ended March 31, 2017 include the following:

• $0.1 million net expense relating to the severance for 2 employees in connection with a reduction to our hardware engineering presence in Shenzhen; and

• $0.2 million in non-recurring legal expenses associated with closing a strategic agreement with a MediaEngine channel partner.

Restructuring and other charges for the three months ended March 31, 2016 include the following:

• $0.7 million net expense relating to the severance for 21 employees primarily in connection with a reduction to our hardware engineering presence in Asia.

Stock-based Compensation Expense

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

	Three Months Ended
	March 31,
	2017		2016		Change
Cost of sales	$	97	$	46	110.9	%
Research and development	230		153		50.3
Selling, general and administrative	827		489		69.1
Total	$	1,154	$	688	67.7	%

25

Stock-based compensation expense increased by $0.5 million for the three months ended March 31, 2017 from the comparable period in 2016 primarily as a result of the timing of new performance-based awards and restricted stock units granted in 2016 and 2017.

Income (Loss) from Operations

The following table summarizes our income (loss) from operations (in thousands):

	Three Months Ended
	March 31,
	2017			2016			Change
Income (loss) from operations
Software-Systems	$	(3,273	)	$	780		(519.6	)%
Hardware Solutions	(1,286		)	1,327			(196.9	)
Corporate and other	(4,576		)	(4,557		)	0.4
Total income (loss) from operations	$	(9,135	)	$	(2,450	)	272.9	%

Software-Systems. Income (loss) from operations declined by $4.1 million to a loss of $3.3 million for the three months ended March 31, 2017 from the comparable period in 2016. This is primarily the result of the previously described $3.3 million decrease in gross margin, partially offset by expenses related to increased headcount in both R&D and SG&A.

Hardware Solutions. Income (loss) from operations declined by $2.6 million to a loss of $1.3 million for the three months ended March 31, 2017 from the comparable period in 2016. This is the result of the previously described $1.2 million decrease in gross margin as well as a $1.4 million increase in operating expenses related to increased headcount in both R&D and SG&A.

Corporate and other. Corporate and other loss from operations include amortization of intangible assets, stock compensation, restructuring and other expenses. Loss from operations was flat at a deficit of $4.6 million for the three months ended March 31, 2017 and 2016.

Non-Operating Expenses

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

	Three Months Ended
	March 31,
	2017			2016			Change
Interest expense	$	(272	)	$	(117	)	132.5	%
Interest income	45			38			18.4
Other income (expense), net	(342		)	101			(438.6	)
Total	$	(569	)	$	22		(2,686.4	)%

Interest Expense

Interest expense includes interest incurred on our revolving line of credit. The increase in interest expense for the three months ended March 31, 2017 from the comparable period in 2016 is the result of intra-quarter draws on our line of credit for working capital needs.

Other Income, Net

For the three months ended March 31, 2017, other income declined $0.4 million from the comparable period in 2016. The decline is primarily due to currency movements, primarily the Indian Rupee and Chinese Yuan, against the US Dollar.

26

Income Tax Provision

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

	Three Months Ended
	March 31,
	2017		2016		Change
Income tax expense	$	304	$	537	(43.4	)%

We recorded tax expense of $0.3 million for the three months ended March 31, 2017. Our effective tax rates for the three months ended March 31, 2017 and 2016 were 3.1% and 22.1%, respectively. The effective tax rate fluctuation is due to an increase of $7.3 million in net loss before income tax expense as well as income tax rate differences among the jurisdictions in which pretax income (loss) is generated, as well as the impact of the full valuation allowance against our U.S. net deferred tax assets.

Liquidity and Capital Resources

The following table summarizes selected financial information as of the dates indicated (in thousands):

	March 31, 2017		December 31, 2016		March 31, 2016
Cash and cash equivalents	$	32,025	$	33,087	$	22,383
Working capital	28,853		32,974		30,551
Accounts receivable, net	49,925		38,378		38,813

Accounts payable	13,674		20,805		31,214
Line of credit	40,000		25,000		15,000

Cash Flows

As of March 31, 2017, the amount of cash held by our foreign subsidiaries was $9.5 million. We do not 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 significant cash tax payments due to the utilization of previously generated operating losses of our U.S. entity.

Cash and cash equivalents decreased by $1.1 million to $32.0 million as of March 31, 2017 from $33.1 million as of December 31, 2016. Activities impacting cash and cash equivalents were as follows (in thousands):

	Three Months Ended
	March 31,
	2017			2016
Operating Activities
Net loss	(10,008		)	$	(2,965	)
Non-cash adjustments	6,224			5,683
Changes in operating assets and liabilities	(10,727		)	(1,036		)
Cash provided by operating activities	(14,511		)	1,682
Cash used in investing activities	(1,803		)	(422		)
Cash provided by financing activities	14,916			105
Effects of exchange rate changes	336			254
Net increase (decrease) in cash and cash equivalents	$	(1,062	)	$	1,619

Cash used in operating activities during the three months ended March 31, 2017 was $14.5 million. For the three months ended March 31, 2017, primary impacts to changes in our working capital consisted of the following:

27

• Accounts receivable increased by $11.5 million due to the timing of collections and shipments to a tier-one U.S. service provider associated with DCEngine sales;

• Inventories decreased by $8.7 million as the result of the aforementioned DCEngine sales;

• Accounts payable decreased $7.0 million due to decreases in payables related to the fulfillment of DCEngine orders as well as decreases in payables to our contract manufacturer;

• Accrued wages and bonuses decreased $2.4 million due to the payment of accrued severance and accrued bonuses.

• Short-term and long-term deferred revenue increased $1.6 million due to the recognition of deferred service contracts.

Cash used in investing activities during the three months ended March 31, 2017 of $1.8 million was associated with ongoing capital expenditures.

Cash generated in financing activities during the three months ended March 31, 2017 of $14.9 million is primarily due to a $15.0 million net draw on our Silicon Valley Bank line of credit. During the first quarter of 2017, our gross borrowings were $37.0 million and we repaid $22.0 million of the borrowing within the period. We expect to continue to borrow additional funds against our line of credit to meet short term intra-quarter needs on an ongoing basis; however, we expect to repay any such borrowings within the quarter as we navigate the timing of customer payments and payables to our suppliers.

Line of Credit

Our primary source of liquidity, aside from our current working capital, is our ability to borrow under our revolving credit facility. As of March 31, 2017 and December 31, 2016, we had an outstanding balance of $40.0 million and $25.0 million. At March 31, 2017, we had $3.9 million of total borrowing availability remaining under our revolving credit facility. Under the revolving credit facility, we may borrow up to $55.0 million in non-formula advances at fiscal quarter ends, provided that such an advance must be repaid on or before the first business day after the applicable fiscal quarter end and subject to the satisfaction of certain other conditions. Our gross borrowing availability was $43.9 million excluding the quarter end non-formula availability. At March 31, 2017, we were in compliance with all covenants under our revolving credit facility. See Note 6 - Short-Term Borrowings for additional information regarding our revolving credit facility.

Contractual Obligations

Our contractual obligations as of December 31, 2016 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, 2016. For the three months ended March 31, 2017, there have been no material changes in our contractual obligations outside the ordinary course of business. As of March 31, 2017, we have agreements regarding foreign currency forward contracts with total contractual values of $17.0 million that mature through 2017.

In addition to the above, we have approximately $3.5 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

AtMarch 31, 2017, our cash and cash equivalents amounted to $32.0 million. We believe our current cash and cash equivalents, cash expected to be generated from operations, available borrowings under our Silicon Valley Bank line of credit and availability under our $100.0 million unallocated shelf registration statement will satisfy our short and long-term expected working capital needs, capital expenditures, acquisitions, stock repurchases, and other liquidity requirements associated with our present business operations. We believe our current working capital, plus availability under the SVB line of credit, provides sufficient liquidity to operate the business at normal levels; however, to accelerate our growth objectives, we may, among other available options, raise additional capital in the public or private markets or pursue alternative financing arrangements.

Recent Accounting Pronouncements

In October 2016, the FASB issued Accounting standards Update No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory (''ASU 2016-16''). ASU 2016-16 modifies how intra-entity transfer of assets other than inventory are accounted for and presented in the financial statements. ASU 2016-16 is effective for public companies for annual reporting periods beginning after December 15, 2017. We adopted this ASU in the first quarter of 2017. We recognized a tax charge of approximately $2.0 million related to intra-entity transactions other than inventory which could not be previously recognized. The unrecognized tax charge is reflected as an adjustment to retained earnings.

In March 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Shared-Based Payment Accounting (''ASU 2016-09''). ASU 2016-09 simplifies how several aspects of share-based payments are accounted for and presented in the financial statements. ASU 2016-09 is effective for public companies for annual reporting periods beginning after December 15, 2016. We adopted this ASU in the first quarter of 2017. Upon adoption, we no longer use a forfeiture rate in the calculation of stock based compensation expense. The impact of this election did not result in a significant charge to retained earnings from applying an estimated forfeiture rate in previous periods. The balance of the unrecognized excess tax benefits was reversed with the impact recorded to retained earnings and included changes to the valuation allowance as a result of the adoption. We have excess tax benefits for which a benefit could not be previously recognized of approximately $4.5 million. Due to the full valuation allowance on the U.S. deferred tax assets, there was no impact to our financial statements beyond disclosure as a result of this adoption.

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” ASU 2016-02 requires lessees to recognize a lease liability and a right-of-use asset on the balance sheet and aligns many of the underlying principles of the new lessor model with those in Accounting Standards Codification Topic 606, Revenue from Contracts with Customers. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the requirements of ASU 2016-02 and have not yet determined its impact on our condensed consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)," which is the new comprehensive revenue recognition standard that will supersede all existing revenue recognition guidance under U.S. GAAP. The standard's core principle is that a company will recognize revenue when it transfers promised goods or services to a customer in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. ASU 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date," which was issued in August 2015, revised the effective date for this ASU to annual and interim periods beginning on or after December 15, 2017, with early adoption permitted, but not earlier than the original effective date of annual and interim periods beginning on or after December 15, 2016, for public entities.

The new standard permits adoption either by using (i) a full retrospective approach for all periods presented in the period of adoption or (ii) a modified retrospective approach with the cumulative effect of initially applying the new standard recognized at the date of initial application and providing certain additional disclosures. We do not plan to early adopt, and accordingly, we will adopt the new standard effective January 1, 2018.

We currently plan to adopt using the modified retrospective approach. However, a decision regarding the adoption method has not been finalized at this time. The final determination will depend on a number of factors, such as the significance of the impact of the new standard on financial results, system readiness and our ability to accumulate and analyze the information necessary to assess the impact on prior period financial statements, as necessary.

Our evaluation of the impact of the new standard on our accounting policies, processes, and system requirements is ongoing. While we continue to assess all potential impacts under the new standard, we do not believe there will be significant changes to the timing of recognition of hardware sales, software license sales or service contracts.

As part of our preliminary evaluation, we also considered the impact of the guidance in ASC 340-40, Other Assets and Deferred Costs; Contracts with Customers. This guidance requires the capitalization of all incremental costs that we incur to obtain a contract with a customer that we would not have incurred if the contract had not been obtained, provided we expect to recover the costs. We preliminarily believe that there will not be significant changes to the timing of the recognition of sales commissions since our commission plan is earned based on the recognition of revenue; however, there is a potential that the amortization period for commission costs may be longer than the contract term in some cases, as the new cost guidance requires entities to determine whether the costs relate to specific anticipated contracts as well.

29

While we continue to assess the potential impacts of the new standard, including the areas described above, the Company cannot reasonably estimate quantitative information related to the impact of the new standard it its financial statements at this time.

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, 2016.

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, 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 March 31, 2017 the total notional or contractual value of the contracts we held was $17.0 million. These contracts will mature over the next 15 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 $1.6 million, increasing our Indian Rupee hedge asset as of March 31, 2017, to $2.4 million. A 10% favorable fluctuation, in relation to our hedge positions, of the U.S. Dollar relative to the Indian Rupee would result in an adjustment of $1.6 million, decreasing our hedge asset as of March 31, 2017 to a liability of $0.8 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.

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 March 31, 2017, 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, 2016, 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, 2016are 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.

Significant Accounting Policies

Accounting Policies [Abstract]

Significant Accounting Policies

In October 2016, the FASB issued Accounting standards Update No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory (''ASU 2016-16''). ASU 2016-16 modifies how intra-entity transfer of assets other than inventory are accounted for and presented in the financial statements. ASU 2016-16 is effective for public companies for annual reporting periods beginning after December 15, 2017. The Company adopted this ASU in the first quarter of 2017. The Company recognized a tax charge of approximately $2.0 million related to intra-entity transactions other than inventory which could not be previously recognized. The unrecognized tax charge is reflected as an adjustment to retained earnings.

In March 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Shared-Based Payment Accounting (''ASU 2016-09''). ASU 2016-09 simplifies how several aspects of share-based payments are accounted for and presented in the financial statements. ASU 2016-09 is effective for public companies for annual reporting periods beginning after December 15, 2016. The Company adopted this ASU in the first quarter of 2017. Upon adoption, the Company no longer uses a forfeiture rate in the calculation of stock based compensation expense. The impact of this election did not result in a significant charge to retained earnings from applying an estimated forfeiture rate in previous periods. The balance of the unrecognized excess tax benefits was reversed with the impact recorded to retained earnings and included changes to the valuation allowance as a result of the adoption. The Company has excess tax benefits for which a benefit could not be previously recognized of approximately $4.5 million. Due to the full valuation allowance on the U.S. deferred tax assets, there was no impact to the financial statements beyond disclosure as a result of this adoption.

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” ASU 2016-02 requires lessees to recognize a lease liability and a right-of-use asset on the balance sheet and aligns many of the underlying principles of the new lessor model with those in Accounting Standards Codification Topic 606, Revenue from Contracts with Customers. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the requirements of ASU 2016-02 and has not yet determined its impact on the condensed consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)," which is the new comprehensive revenue recognition standard that will supersede all existing revenue recognition guidance under U.S. GAAP. The standard's core principle is that a company will recognize revenue when it transfers promised goods or services to a customer in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. ASU 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date," which was issued in August 2015, revised the effective date for this ASU to annual and interim periods beginning on or after December 15, 2017, with early adoption permitted, but not earlier than the original effective date of annual and interim periods beginning on or after December 15, 2016, for public entities.

The new standard permits adoption either by using (i) a full retrospective approach for all periods presented in the period of adoption or (ii) a modified retrospective approach with the cumulative effect of initially applying the new standard recognized at the date of initial application and providing certain additional disclosures. The Company does not plan to early adopt this new standard, and accordingly, the Company will adopt the new standard effective January 1, 2018.

The Company currently plans to adopt using the modified retrospective approach. However, a decision regarding the adoption method has not been finalized at this time. The final determination will depend on a number of factors, such as the significance of the impact of the new standard on financial results, system readiness and the Company's ability to accumulate and analyze the information necessary to assess the impact on prior period financial statements, as necessary.

The Company's evaluation of the impact of the new standard on the Company's accounting policies, processes, and system requirements is ongoing. While the Company continues to assess all potential impacts under the new standard, the Company does not believe there will be significant changes to the timing of recognition of hardware sales, software license sales or service contracts.

As part of the Company's preliminary evaluation, the Company also considered the impact of the guidance in ASC 340-40, "Other Assets and Deferred Costs; Contracts with Customers". This guidance requires the capitalization of all incremental costs that we incur to obtain a contract with a customer that the Company would not have incurred if the contract had not been obtained, provided the Company expects to recover the costs. The Company preliminarily believes that there will not be significant changes to the timing of the recognition of sales commissions since the Company's commission plan is earned based on the recognition of revenue; however, there is a potential that the amortization period for commission costs may be longer than the contract term in some cases, as the new cost guidance requires entities to determine whether the costs relate to specific anticipated contracts as well.

While the Company continues to assess the potential impacts of the new standard, including the areas described above, the Company cannot reasonably estimate quantitative information related to the impact of the new standard on its financial statements at this time.

Immaterial Revision to Prior Period Financial Statement

The Company has revised the presentation of revenue and cost of sales to separately present those amounts that are associated with service and related activities from those amounts associated with product sales. This change does not impact the Company’s previously reported total revenues, gross margin, loss from operations or net loss for the periods presented.

Fair Value Disclosures [Abstract]

Fair Value Disclosures

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

	Fair Value Measurements as of March 31, 2017
	Total		Level 1	Level 2		Level 3
Foreign currency forward contracts	$	846	—	$	846	—

Short-Term Borrowings

Silicon Valley Bank

On September 19, 2016, the Company entered into a Credit Agreement (as amended, the “Credit Agreement”) with Silicon Valley Bank (“SVB”), as administrative agent, and the other lenders party thereto. The Credit Agreement replaces the Company’s Third Amended and Restated Loan and Security Agreement with SVB, dated March 14, 2014 (as amended, the “2014 Agreement”). On January 5, 2017, the Company entered into the First Amendment to the Credit Agreement. The following takes into account the terms per the agreement as amended on January 5, 2017.

The Credit Agreement provides for a revolving loan commitment of $55.0 million and has a stated maturity date of September 19, 2019. The Credit Agreement includes a $10.0 million sub-limit for swingline loans and a $10.0 million sub-limit for letters of credit. The Credit Agreement also includes an accordion feature that allows the Company, at any time, to increase the aggregate revolving loan commitments by up to an additional $25.0 million, subject to the satisfaction of certain conditions, including obtaining the lenders’ agreement to participate in the increase.

Borrowings under the Credit Agreement are subject to a borrowing base, which is a formula based upon certain eligible accounts receivable plus up to $7.5 million if the Company’s Liquidity (as defined in the Credit Agreement) is above $20.0 million in the first and second month of any fiscal quarter and $25.0 million for the last month of a fiscal quarter, measured as of the last day of the applicable month. Eligible accounts receivable include 85% of certain U.S. and 75% of certain foreign accounts receivable (85% in certain cases). The Credit Agreement also provides for non-formula advances during the last business day of any fiscal quarter, provided that Liquidity on the date of a requested non-formula advance must be greater than or equal to $40.0 million, the non-formula advance must be repaid on or before the first business day after the applicable fiscal quarter end, and subject to the satisfaction of certain other conditions.

Outstanding borrowings under the revolving loan commitment bear interest at a per annum rate based upon the Company's Availability (as defined in the Credit Agreement), which means the quotient of the amount available for borrowings under the Credit Agreement divided by the lesser of the total commitment and the borrowing base, calculated as a daily average over the immediately preceding fiscal month. The Credit Agreement provides that the per annum interest rate on or before March 31, 2017 and at any time thereafter when the Consolidated Adjusted EBITDA (as defined in the Credit Agreement) as measured on a trailing twelve-month basis for the immediately preceding fiscal quarter period is less than the Consolidated Adjusted EBITDA threshold as specified in the Credit Agreement will be as follows:

• When Availability is 70% or more, the interest rate is the prime rate (as published in Wall Street Journal) plus 0.50%;

• When Availability is 30% or more and less than 70%, the interest rate is the prime rate plus 0.75%; and

• When Availability is below 30%, the interest rate is the prime rate plus 1.00%.

After March 31, 2017, if Consolidated Adjusted EBITDA as measured on a trailing twelve-month basis for the immediately preceding fiscal quarter period is equal to or greater than the Consolidated Adjusted EBITDA threshold as specified in the Credit Agreement, the rate per annum will be as follows:

• When Availability is 70% or more, the interest rate is the prime rate plus 0.25%;

• When Availability is 30% or more and less than 70%, the interest rate is the prime rate plus 0.50%; and

• When Availability is below 30%, the interest rate is the prime rate plus 0.75%.

Under the Credit Agreement, the Company is required to make interest payments monthly. The Company is further required to pay $25,000 in annual administrative fees, $82,500 in annual commitment fees and a commitment fee based on the average unused portion of the revolving credit commitment, and certain other fees in connection with letters of credit. The commitment fee is determined as follows and is payable quarterly in arrears:

• When Availability is 70% or more, the commitment fee is 0.35% of the average unused portion of the revolving credit commitment;

• When Availability is 30% or more and less than 70%, the commitment fee is 0.325% of the average unused portion of the revolving credit commitment; and

• When Availability is below 30%, the commitment fee is 0.3% of the average unused portion of the revolving credit commitment.

The Company paid a total of $0.3 million loan origination fees which were capitalized and will be expensed over the term of the Credit Agreement. If the Company reduces or terminates the revolving loan commitment under the Credit Agreement prior to September 19, 2017, the Company is required to pay a cancellation fee equal to 0.75% of the total revolving loan commitment.

The Credit Agreement requires that the Company comply with financial covenants requiring the Company to maintain a minimum monthly Liquidity of $15.0 million as of the last day of the first and second month of any fiscal quarter and $20.0 million as of the last day of the third month of any fiscal quarter. Additionally, the Credit Agreement requires the Company to maintain a minimum trailing twelve months Consolidated Adjusted EBITDA each quarter of fiscal year 2017. The Credit Agreement also provides that following fiscal year 2017, SVB, as administrative agent, and the required lenders under the Credit Agreement will re-set the required minimum Consolidated Adjusted EBITDA levels for the periods tested in fiscal years 2018 and 2019.

All obligations under the 2016 Agreement are unconditionally guaranteed by the Company's wholly owned subsidiary, Radisys International LLC. The obligations under the Credit Agreement are secured by a first priority lien on the assets of the Company and the subsidiary guarantor. If the Company acquires or forms a material U.S. subsidiary, then that subsidiary will also be required to guarantee the obligations under the Credit Agreement and grant a first priority lien on its assets.

As of March 31, 2017 and December 31, 2016, the Company had an outstanding balance of $40.0 million and $25.0 million under the Credit Agreement. At March 31, 2017, the Company had $3.9 million of total borrowing availability remaining under the Credit Agreement. Under the First Amendment, the Company may borrow up to $55.0 million at fiscal quarter ends. The Company's gross borrowing availability was $43.9 million excluding the quarter end non-formula availability. At March 31, 2017, the Company was in compliance with all covenants under the Amended Agreement.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies Disclosure

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. 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 and Deferred Cost of Sales).

The adverse purchase commitment liability is included in other accrued liabilities in the accompanying Condensed Consolidated Balance Sheets and was $0.5 million and $0.3 million as of March 31, 2017 and December 31, 2016.

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 March 31, 2017.

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.

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 to 24 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):

	Three Months Ended

Income Taxes

The Company's effective tax rate for the three months ended March 31, 2017 differs from the statutory rate due to a full valuation allowance provided against its United States (“U.S.”) net deferred tax assets, 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 March 31, 2017. 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 $1.0 million and $1.1 million at March 31, 2017 and December 31, 2016. 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 ending balance for the unrecognized tax benefits for uncertain tax positions was approximately $3.5 million at March 31, 2017. The related interest and penalties were $0.8 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, 2006, 2008 and 2011. The examinations are 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 March 31, 2017. The Company is currently under tax examination in Canada. The periods covered under examination in Canada are the Company's financial years 2013 and 2014. No examination adjustments have been proposed. As of March 31, 2017, the Company is not under examination by tax authorities in any other jurisdictions.

Hedging

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 March 31, 2017 and December 31, 2016, 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 (loss) is affected by the variability of the cash flows of the hedged transaction. Typically, hedge ineffectiveness could result when the amount of the Company’s hedge contracts exceed the Company’s forecasted or actual transactions for which the hedge contracts were designed to hedge. Once a hedge contract matures, the associated gain (loss) on the contract will remain in other comprehensive income (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 months ended March 31, 2017 and 2016, the Company had no hedge ineffectiveness.

During thethreemonths ended March 31, 2017 the Company entered into 6 new foreign currency forward contracts, with total contractual values of $3.6 million. During the three months ended March 31, 2016, the Company entered into 12 new foreign currency contracts, with total contractual values of $3.6 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 March 31, 2017 is as follows (in thousands):

Over the next twelve months, the Company expects to reclassify into earnings income of approximately $0.4 million currently recorded as accumulated 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.
