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, 2015 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, 2016 and for the three months ended March 31, 2016 and 2015 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, 2015.

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

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

Recent Accounting Pronouncements

In March 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-09, “Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” ASU 2016-09 simplifies the accounting for share-based payment award transactions including: income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the requirements of ASU 2016-09 and have not yet determined its impact on the condensed consolidated financial statements.

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 have 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. Entities will have the option of using either a full retrospective approach or a modified approach to adopt the guidance in ASU 2014-09. The Company is currently evaluating the requirements of ASU 2015-14 and have not yet determined its impact on the condensed consolidated financial statements.

Note 2 — Fair Value of Financial Instruments

Assets and Liabilities Measured at Fair Value on a Recurring Basis

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

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

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

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

Foreign currency forward contracts are measured at fair value using models based on observable market inputs such as foreign currency exchange rates; therefore, they are classified within Level 2 of the valuation hierarchy.

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



	Fair Value Measurements as of March 31, 2016
	Total			Level 1	Level 2			Level 3
Foreign currency forward contracts	$	(4	)	—	$	(4	)	—



	Fair Value Measurements as of December 31, 2015
	Total			Level 1	Level 2			Level 3
Foreign currency forward contracts	$	(277	)	—	$	(277	)	—

Note 3 — Accounts Receivable and Other Receivables

	March 31, 2016			December 31, 2015
Accounts receivable, gross	$	38,920		$	61,045
Less: allowance for doubtful accounts	(107		)	(103		)
Accounts receivable, net	$	38,813		$	60,942

As of March 31, 2016 and December 31, 2015, the balance in other receivables was $3.1 million and $11.3 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 and Deferred Cost of Sales

Inventories consisted of the following (in thousands):



	March 31, 2016			December 31, 2015
Raw materials	$	27,610		$	14,546
Work-in-process	218			98

Less: inventory valuation allowance	(4,233		)	(5,317		)
Inventories, net	$	30,095		$	16,812

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 inventory, consisting of raw materials and finished goods was $9.3 million and $11.5 million at March 31, 2016 and December 31, 2015.

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 is contractually obligated to purchase inventory transferred from the Company's prior contract manufacturer after the inventory ages for 365 days. The Company is also contractually obligated to purchase inventory that has been 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 consignment inventory at its contract manufacturing partner was $8.1 million and $8.7 million as of March 31, 2016 and December 31, 2015. The Company records a liability for adverse purchase commitments of inventory owned by its contract manufacturing partner. See Note 8 - 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 liability (in thousands):



	Three Months Ended

Deferred cost of sales, which are directly associated with deferred revenue on shipments to customers, was $0.0 million and $14.1 million at March 31, 2016 and December 31, 2015.

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

	2016		2015
Employee-related restructuring expenses	$	682	$	4,033
Integration-related and other non-recurring expenses	—		(7		)
Non-recurring legal expenses	—		109
Restructuring and other charges, net	$	682	$	4,135

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, 2016, the Company recorded the following restructuring charge:


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

For the three months ended March 31, 2015, the Company recorded the following restructuring and other charges:


•	$4.0 million net expense relating to the severance of employees in connection with the previously reported Penang site closure, as well as severance for four additional employees, net of reductions resulting from changes in previously estimated amounts for employee severance and associated payroll costs; and


•	$0.1 million legal expenses associated with non-operating strategic projects.

Accrued restructuring, which is included in other accrued liabilities and other long-term liabilities in the accompanying Condensed Consolidated Balance Sheets as of March 31, 2016 and December 31, 2015, consisted of the following (in thousands):



	Severance, payroll taxes and other employee benefits			Facility reductions			Total

Of the $1.1 million accrued restructuring at March 31, 2016, $0.1 million is included in other long-term liabilities, with the remaining balance being included in other accrued liabilities on the Condensed Consolidated Balance Sheets.

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 March 14, 2014, the Company entered into an amended and restated $25.0 million revolving line of credit agreement with Silicon Valley Bank ("SVB") (the "2014 Agreement") which has a stated maturity date of July 28, 2016. On May 30, 2014, the 2014 Agreement was amended to increase the letter of credit sublimit under the secured revolving credit facility from $1.0 million to $2.0 million. On April 23, 2015, the 2014 Agreement was amended to further increase the letter of credit sublimit under the secured revolving credit facility from $2.0 million to $5.0 million or the net borrowing availability. On February 8, 2016, the 2014 Agreement was amended to increase the revolving line of credit to $35.0 million (as amended, the "Amended Agreement") and to extend the stated maturity date to February 8, 2018. The secured revolving credit facility under the Amended Agreement is available for cash borrowings and is subject to a borrowing formula based upon eligible accounts receivable less outstanding letters of credit (aggregate letters of credit are not to exceed $5.0 million). Eligible accounts receivable include 80% of U.S. and 75% of foreign accounts receivable (80% in certain cases), not greater than 60 days past original invoice date. The interest rate is dependent upon the Company's Liquidity (as defined in the Amended Agreement) when compared to a pre-determined threshold (the "Liquidity Threshold"), which is defined in the Amended Agreement as $15.0 million, with the exception of the last month end of each quarter, where it is defined as $20.0 million. Liquidity is calculated under the Amended Agreement as unrestricted cash plus unused availability on the revolving line of credit. The calculation of interest under the 2014 Agreement is as follows:


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


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


•

Under the Amended Agreement, the Company is required to make interest payments monthly. The Company is further required to pay a loan modification fee of $35,000 and pay a facility fee of $52,500 annually. The Company paid a prorated facility fee equal to $48,000 in February 2016 and will pay the full facility fee of $52,500 annually thereafter. Under the Amended Agreement, the Company is required to pay the higher of actual monthly interest incurred or the interest equivalent of $10.0 million in average monthly borrowings. If the Company terminates the commitment under the Amended Agreement prior to the maturity date, the Company is required to pay a cancellation fee equal to 1.5% of the commitment under the Amended Agreement. The Amended Agreement removed the former requirement to maintain a deposit account balance of at least $4.0 million with SVB or its affiliates and the former requirement that at least 50% of the Company's cash must be deposited with SVB or its affiliates or in an account where SVB has a control agreement. The Amended Agreement did not otherwise change the requirement to maintain all the Company's US domestic cash accounts with SVB or an SVB affiliate.

The Amended Agreement requires the Company to make certain representations, warranties and other agreements that are customary in credit agreements of this type. The Amended Agreement also includes financial covenants that requires the Company to maintain minimum Liquidity of $10.0 million, which is tested monthly. Additionally, the Amended Agreement requires the Company to maintain a minimum adjusted EBITDA of at least $10.0 million if the outstanding principal balance is greater than $15.0 million or maintain a minimum adjusted EBITDA of at least $7.5 million if the outstanding principal balance is equal to or less than $15.0 million, which is tested quarterly. The Amended Agreement defines Adjusted EBITDA as net income plus interest expense, depreciation expense, amortization expense, income tax expense, non-cash stock compensation expense and restructuring expense (limited to $1.7 million, $1.14 million, $1.0 million at the first, second and third quarter 2016 measurement dates and $0 thereafter).

As of March 31, 2016 and December 31, 2015, the Company had an outstanding balance of $15.0 million under the Amended Agreement. At March 31, 2016, the Company had $11.6 million of total borrowing availability remaining under the Amended Agreement. At March 31, 2016, the Company was in compliance with all covenants under the Amended Agreement.

Note 7 — Convertible Debt

2015 Convertible Senior Notes

On February 17, 2015, the Company repaid at maturity the entire outstanding balance of the 4.5% convertible senior notes due 2015 (the "2015 convertible senior notes") in accordance with the terms thereof. No convertible senior notes were converted to common stock.

Note 8 — Commitments and Contingencies

Adverse Purchase Commitments

The Company is contractually obligated to reimburse its contract manufacturer for the cost of excess inventory used in the manufacture of the Company's products if there is no alternative use. 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 $2.5 million and $2.2 million as of March 31, 2016 and December 31, 2015.

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, 2016.

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,
	2016			2015
Warranty liability balance, beginning of the period	$	2,553		$	2,600

Note 10 — Income Taxes

The Company's effective tax rate for the three months ended March 31, 2016 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, 2016. 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 $1.2 million at March 31, 2016 and December 31, 2015. 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 was approximately $3.7 million at March 31, 2016. The related interest and penalties were $0.7 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 2006, 2007 and 2010 through 2012. The examination is in various stages of appellate proceedings and all material uncertain tax positions associated with the examination have been taken into account in the ending balance of the unrecognized tax benefits at March 31, 2016. As of March 31, 2016, the Company is not under examination by tax authorities in any other jurisdictions.

Note 11 — Stock-based Compensation

Performance based restricted stock awards ^(A)	680	1,450
Total	1,716	2,010

(A)

On March 28, 2016, the Compensation Committee approved grants of performance-based restricted stock units ("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 during fiscal year 2017 on meeting targets of strategic revenue, 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 performance conditions.

On March 2, 2015, the Compensation Committee approved PRSUs with a performance period starting on March 2, 2015 and ending on March 2, 2019, which provides that on the performance measurement date following the achievement of the following market condition stock price hurdles:


•	50% of the awards will be earned if Radisys’ average closing stock price over a 30-trading day period is equal to or greater than $3.45 during a 3-year performance period.


•	50% of the awards will be earned if Radisys’ average closing stock price over a 30-trading day period is equal to or greater than $4.25 during a 4-year performance period.

If either of the stock price hurdles is not met during their respective performance period, that portion of the award will be forfeited.

Note 12 — Hedging

The Company’s activities expose it to a variety of market risks, including the effects of changes in foreign currency exchange rates. The Company manages these risks through the use of forward exchange contracts, designated as foreign-

currency cash flow hedges, in an attempt to reduce the potentially adverse effects of foreign currency exchange rate fluctuations that occur in the normal course of business. As such, the Company’s hedging activities are employed solely for risk management purposes. All hedging transactions are conducted with, in the opinion of management, financially stable and reputable financial institutions. As of March 31, 2016 and December 31, 2015, 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, 2016 and 2015, the Company had no hedge ineffectiveness.

During the three months ended March 31, 2016 the Company entered into 12 new foreign currency forward contracts, with total contractual values of $3.6 million. During the three months ended March 31, 2015, the Company did not enter into any new foreign currency contracts.

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, 2016 is as follows (in thousands):



	Contractual/ Notional Amount		Condensed Consolidated Balance Sheet Classification	Estimated Fair Value
Type of Cash Flow Hedge	Contractual/ Notional Amount		Condensed Consolidated Balance Sheet Classification	Asset		(Liability)

Amounts reclassified from other comprehensive income	348			(9		)
Other comprehensive income (loss)	134			118
Ending balance of unrealized loss on forward exchange contracts	$	(685	)	$	(634	)

Over the next twelve months, the Company expects to reclassify into earnings a loss of approximately $0.8 million currently recorded as accumulated other comprehensive income (loss), 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, 2015. 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 as well as their strategic partners create new revenue streams and drive cost out of their services delivery infrastructure. Radisys’ application aware traffic distribution platforms, real-time media processing engines and wireless access technologies enable service providers to maximize, virtualize and monetize their networks. These products help accelerate our customer's ability to bring high-value telecom applications to market faster and with lower investment and risk. Our products and services fall within two operating segments: Software-Systems and Embedded Products and Hardware Services.


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

◦

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 carriers 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, which includes our TOTALeNodeB LTE and Femtotality 3G software products, provides the communication linkage between wireless end user devices and mobile core networks through small cell base stations that mobile carriers are deploying to optimize wireless network spectrum utilization and coverage. Our focus is providing software protocol stacks and applications that enable small 3G and LTE operator-controlled, low-power wireless base stations (known as small cells, femtocells, enterprise femtocells and picocells), which enable improved cellular coverage and capacity for homes and enterprises as well as metropolitan and rural areas. CellEngine software technology is typically sold to small cell access point solution vendors requiring a common software and baseband processing platform that is already pre-integrated with leading eNodeB System on Chip ("SOC") vendors. Additionally, we leverage our CellEngine technology to enable small cell 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 customers integrate them into complete systems.

•

Embedded Products and Hardware Services are predominantly hardware-based products, including our newly-launched data center product, DCEngine, that enable the control and movement of data in both 3G and LTE telecom networks as well as bring the economies of the data center and the agility of the cloud to service provider infrastructure. DCEngine is a compute, storage and networking platform built on open hardware standards and open source software to drive innovation and the rapid delivery of new services such as video on demand, Internet Protocol Television ("IPTV") and parental control capabilities. Our products also enable network elements for applications such as Deep Packet Inspection ("DPI"), policy management and intelligent gateways (security, femto and LTE gateways) as well as accelerate the transformation to cloud based hyper scale compute, storage and network fabrics. 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 2016 Summary

During the quarter, we formally launched our new data center product, DCEngine, a hyper-scale infrastructure solution for both telecom and cable operators that enables the virtualization of existing networks by providing the hardware and software basic building blocks necessary to deploy SDN and NFV. DCEngine is strategically important as it positions us with a more complete offering of software, systems and services which all support the migration of operators towards virtualization of their networks.

In the first quarter of 2016 consolidated revenue grew $6.5 million, or 13%, year-on-year as the result of continued momentum across all of our growth initiatives. We realized revenue growth in both of our segments including growth of $4.4 million or 45% in our Software-Systems segment and $2.1 million or 5.4% in our Embedded Products and Hardware Services segment. Revenue growth in Software-Systems was the result of continued strong FlowEngine shipments in support of the commercial deployment by a tier-one U.S. service provider as well as MediaEngine demand in support of both VoLTE deployments and audio conferencing to cloud-based installations. In our Embedded Products and Hardware Services segment, growth was driven by the recognition of previously deferred DCEngine revenues relating to sales to a tier-one U.S. service provider which were recognized upon installation and commissioning of initial systems during the first quarter of 2016.

The following is a summary-level comparison of the three months ended March 31, 2016 and 2015:

•

Revenues increased $6.5 million to $55.1 million for the three months ended March 31, 2016 from $48.7 million for the three months ended March 31, 2015. Software-Systems revenue increased $4.4 million due to a continued strong MediaEngine and FlowEngine demand. Embedded Products and Hardware Services revenue increased $2.1 million, due to meaningful revenue in our new DCEngine product line offset by declines in non-core legacy products.


•	Our gross margin decreased 270 basis points to 23.2% for the three months ended March 31, 2016 from 25.9% for the three months ended March 31, 2015, which was the result of a lower margin product mix as we recognized $19.7 million of lower margin DCEngine sales in the current quarter combined with higher initial costs associated with the initial deployment of DCENgine systems.


•	R&D expense decreased $1.1 million to $5.7 million for the three months ended March 31, 2016 from $6.7 million for the three months ended March 31, 2015. The expense decrease is attributable to our restructuring efforts including the 2015 headcount reduction in our Embedded Products and Hardware Services segment.


•	SG&A expense increased $0.1 million to $7.6 million for the three months ended March 31, 2016 from $7.5 million for the three months ended March 31, 2015. This is due to a $0.3 million increase in commissions and incentive compensation offset by salary expense reductions that resulted from our 2015 restructuring activities.


•	Cash and cash equivalents on March 31, 2016 increased $1.6 million to $22.4 million from $20.8 million at December 31, 2015. The increase was the result of cash generation from operations of $1.7 million, offset by capital expenditures of $0.4 million.

•

Deferred revenue on March 31, 2016 decreased $16.7 million to $6.4 million from $23.1 million at December 31, 2015 and deferred cost of sales decreased $14.1 million over the same period. These decreases were primarily attributable to the recognition of previously deferred DCEngine revenues relating to sales to a tier-one U.S. service provider which were recognized upon installation and commissioning of initial systems during the first quarter of 2016.


•	Accounts receivable on March 31, 2016 decreased $22.1 million to $38.8 million from $60.9 million at December 31, 2015. The decrease was primarily attributable to collections associated with the aforementioned DCEngine shipments during the first quarter of 2016.

Embedded Products and Hardware Services	41,087		38,998		5.4
Total revenues	$	55,146	$	48,687	13.3	%

Software-Systems. Revenues in the Software-Systems segment increased $4.4 million for the three months ended March 31, 2016 from the comparable period in 2015. Revenue growth of $1.9 million in the three months ended March 31, 2016 was attributable to follow-on orders from the large Asian carrier currently deploying our MediaEngine products in support of their greenfield LTE network rollout. Additionally, over the same period, we increased our FlowEngine shipments by $3.2 million to a tier-one U.S. service provider in support of their commercial deployment. These increases were offset by a decline in CellEngine license sales.

Embedded Products and Hardware Services. Revenues in the Embedded Products and Hardware Services product group increased $2.1 million for the three months ended March 31, 2016 from the comparable period in 2015. The increase is a result of $19.7 million growth in our new data center product, DCEngine, in sales to a tier-one U.S. service provider. This was offset by a decrease of $17.6 million in non-core legacy hardware products, which is a result of the strategic changes implemented early in 2015 to focus on key customers who have adequate scale to meet our profitability objectives and to enable us to generate steady levels of profitability and cash flow over the coming years.

Asia Pacific	13.8		35.3
EMEA	17.6		21.1
Total	100.0	%	100.0	%

North America. Revenues from the North America region increased $16.6 million for the three months ended March 31, 2016 from the comparable period in 2015. This is primarily attributable to increased sales to a tier-one U.S. service provider purchasing both DCEngine and FlowEngine products in support of various commercial deployments.

Asia Pacific. Revenues from the Asia Pacific region decreased $9.6 million for the three months ended March 31, 2016 from the comparable period in 2015. The decrease was primarily attributed to a $9.1 million decrease in sales of non-core legacy Embedded Products and Hardware Services that have been trending to end-of-life from two of our larger Asian customers.

EMEA. Revenues from the EMEA region decreased $0.6 million for the three months ended March 31, 2016 from the comparable period in 2015. The decrease was attributable to a $1.5 million reduction in sales to an Embedded Products and Hardware Services customer which had a large deployment in the first quarter of 2015 that was not repeated in the current quarter. This was offset by continued strong demand 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.

Total gross margin	23.2	%	25.9	%	(10.4	)%

Software-Systems. Gross margin increased 750 basis points to 62.5% for the three months ended March 31, 2016 from 55.0% in the comparable period of 2015 largely as the result of improved product mix and growth in overall product sales. Product related revenue in this segment grew by $4.8 million driving the improvement of the overall gross margin.

Embedded Products and Hardware Services. Gross margin decreased 950 basis points to 14.5% for the three months ended March 31, 2016 from 24.0% in the comparable period in 2015. This was primarily attributable to the $19.7 million increase in DCEngine sales to a tier-one U.S. service provider, as this product line carries proportionately lower margins than other products within the Embedded Products and Hardware Services segment, coupled with meaningful expenses associated with the initial installation and commissioning of these systems.

Corporate and other. Gross margin was flat at a deficit of $2.0 million for the three months ended March 31, 2016 and 2015. 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, 2016 and 2015 (in thousands):



	Three Months Ended
	March 31,
	2016		2015		Change
Research and development	$	5,653	$	6,724	(15.9)%
Selling, general and administrative	7,639		7,500		1.9
Intangible asset amortization	1,260		1,260		—
Restructuring and other charges, net	682		4,135		(83.5)
Total	$	15,234	$	19,619	(22.4)%

Research and Development

R&D expenses consist primarily of personnel costs, product development costs, and related equipment expenses. R&D expenses decreased $1.1 million for the three months ended March 31, 2016 from the comparable period in 2015. The expense reductions are due to our restructuring efforts within our Embedded Products and Hardware Services segment which included personnel reductions in the first half of 2015 primarily in Asia and North America. This resulted in reductions to salary expense by $1.1 million for the three months ended March 31, 2016 from the comparable period in 2015. R&D headcount decreased year over year to 301 at March 31, 2016 from 360 at March 31, 2015.

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 $0.1 million for the three months ended March 31, 2016 from the comparable period in 2015. Restructuring efforts in the first half of 2015 within our Embedded Products and Hardware Service segment drove headcount reductions and contributed to a decrease in employee salary of $0.3 million for the three months ended March 31, 2016. This was offset by an increase of $0.3 million in commissions driven by higher revenues and incentive compensation. SG&A headcount decreased to 114 at March 31, 2016 from 124 at March 31, 2015.

Intangible Asset Amortization

Intangible asset amortization for the three months ended March 31, 2016 was comparable with the same period in 2015 due to routine amortization of acquired intangible assets. No triggering events occurred during the quarter ended March 31, 2016 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 $3.5 million to $0.7 million for the three months ended March 31, 2016 from $4.1 million in the comparable period in 2015.

Restructuring and other charges, net 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 Shenzhen.

Restructuring and other charges for the three months ended March 31, 2015 include the following:


•	$4.0 million net expense relating to the severance of employees in connection with the previously reported Penang development site closure, as well as severance for four additional employees, net of reductions resulting from changes in previously estimated amounts for employee severance and associated payroll costs; and


•	$0.1 million legal expenses associated with non-operating strategic projects.

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,
	2016		2015		Change
Cost of sales	$	46	$	53	(13.2	)%
Research and development	153		132		15.9
Selling, general and administrative	489		474		3.2
Total	$	688	$	659	4.4	%

Stock-based compensation expense was flat for the three months ended March 31, 2016 from the comparable period in 2015. Performance based awards and stock options were granted during the final weeks of the first quarter 2016, resulting in a nominal impact on quarter over quarter expenses.

Income (Loss) from Operations

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



	Three Months Ended
	March 31,
	2016			2015			Change
Income (loss) from operations
Software-Systems	$	780		$	(2,902	)	126.9	%
Embedded Products and Hardware Services	1,327			3,957			(66.5	)
Corporate and other	(4,557		)	(8,048		)	43.4
Total income (loss) from operations	$	(2,450	)	$	(6,993	)	65.0	%

Software-Systems. Income (loss) from operations improved by $3.7 million for the three months ended March 31, 2016 from the comparable period in 2015. This was driven by the previously described 45.1% year on year revenue growth and $3.5 million increase in gross margin for the three months ended March 31, 2016 from the comparable period of 2015.

Embedded Products and Hardware Services. Income from operations decreased by $2.6 million for the three months ended March 31, 2016 from the comparable period in 2015. The decrease was primarily driven by the $3.4 million decrease in gross margin for the three months ended March 31, 2016 driven by a lower margin product mix and offset by the decrease in operating expenses resulting from the rationalization of spending within this segment.

Corporate and other. Corporate and other loss from operations include amortization of intangible assets, stock compensation, restructuring and other expenses. Loss from operations improved $3.5 million to $4.6 million for the three months ended March 31, 2016 from $8.0 million in the comparable period in 2015 as the result of the previously described restructuring actions.

Non-Operating Expenses

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



	Three Months Ended
	March 31,
	2016			2015			Change
Interest expense	$	(117	)	$	(217	)	46.1	%
Interest income	38			47			(19.1	)
Other income, net	101			350			(71.1	)
Total	$	22		$	180		(87.8	)%

Interest Expense

Interest expense includes interest incurred on our convertible senior notes and our revolving line of credit. We repaid the $18 million 2015 convertible senior notes on February 17, 2015 which resulted in lower interest expense in the three months ended March 31, 2016 compared to the same period in the prior year.

Other Income, Net

For the three months ended March 31, 2016, other income decreased $0.2 million from the comparable periods in 2015 primarily due to unfavorable cash flow hedge exchange rates between the Indian Rupee and the US Dollar and unfavorable currency movements due to weakening of the US Dollar.

Income Tax Provision

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



	Three Months Ended
	March 31,
	2016		2015		Change
Income tax expense	$	537	$	240	123.8	%

We recorded tax expense of $0.5 million for the three months ended March 31, 2016. Our effective tax rates for the three months ended March 31, 2016 and 2015 were 22.1% and 3.5%, respectively. The effective tax rate fluctuation is due to an improvement of $4.4 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, coupled with 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, 2016		December 31, 2015		March 31, 2015
Cash and cash equivalents	$	22,383	$	20,764	$	15,846

Accounts payable	31,214		43,451		23,385
Line of credit	15,000		15,000		10,000

Cash Flows

As of March 31, 2016, the amount of cash held by our foreign subsidiaries was $7.7 million. It is not our intent to permanently reinvest funds in certain of our foreign entities, and we expect to repatriate cash from these foreign entities on an ongoing basis in future periods. Repatriation of funds from these foreign entities is not expected to result in significant cash tax payments due to the utilization of previously generated operating losses of our U.S. entity.

Cash and cash equivalents increased by $1.6 million to $22.4 million as of March 31, 2016 from $20.8 million as of December 31, 2015. Activities impacting cash and cash equivalents were as follows (in thousands):



	Three Months Ended
	March 31,
	2016			2015
Operating Activities
Net loss	$	(2,965	)	$	(7,053	)
Non-cash adjustments	5,683			5,821
Changes in operating assets and liabilities	(1,036		)	4,860
Cash provided by (used in) operating activities	1,682			3,628
Cash used in investing activities	(422		)	(640		)
Cash provided by (used in) financing activities	105			(17,992		)
Effects of exchange rate changes	254			(392		)
Net increase (decrease) in cash and cash equivalents	$	1,619		$	(15,396	)

Cash generated by operating activities during the three months ended March 31, 2016 was $1.7 million. For the three months ended March 31, 2016, primary impacts to changes in our working capital consisted of the following:


•	Accounts receivable decreased by $22.1 million driven by $19.3 million in collections from a tier-one U.S. service provider primarily related to DCEngine shipments;


•	Inventories and deferred costs of goods sold net decreased by $0.6 million. Deferred cost of sales decreased $14.1 million due to recognition of the associated deferred DCEngine revenue. This was offset by a $13.3 million increase in inventories primarily due to the purchase of component inventory to support order backlog for our DCEngine products;


•	Accounts payable decreased $12.2 million due to a decrease in payables related to the DCEngine during the prior quarter as well as a decrease in payables to our contract manufacturer;


•	Deferred revenue decreased $16.7 million due to the recognition of the $17.8 million balance associated with DCEngine orders deferred at year end.

Cash used in investing activities during the three months ended March 31, 2016 of $0.4 million was associated with ongoing capital expenditures.

Cash generated in financing activities during the three months ended March 31, 2016 of $0.1 million is due to the proceeds from issuance of common stock. During the first quarter of 2016, we borrowed gross draws of $18.0 million on our Silicon Valley Bank line of credit to meet intra-period cash requirements and repaid the borrowing within the period. We may 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 contract manufacturer.

Line of Credit

Silicon Valley Bank

calculated under the Amended Agreement as unrestricted cash plus unused availability on the revolving line of credit. The calculation of interest under the 2014 Agreement is as follows:


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


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


•

As of March 31, 2016 and December 31, 2015, we had an outstanding balance of $15.0 million under the Amended Agreement. At March 31, 2016, we had $11.6 million of total borrowing availability remaining under the Agreement. At March 31, 2016, we were in compliance with all covenants under the Amended Agreement.

Contractual Obligations

Our contractual obligations as of December 31, 2015 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, 2015. For the three months ended March 31, 2016, there have been no material changes in our contractual obligations outside the ordinary course of business. As of March 31, 2016, we have agreements regarding foreign currency forward contracts with total contractual values of $13.9 million that mature through 2016.

In addition to the above, we have approximately $3.7 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

At March 31, 2016, our cash and cash equivalents amounted to $22.4 million. We believe our current cash and cash equivalents, cash expected to be generated from operations and borrowings under our Silicon Valley Bank line of credit 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, if available liquidity is not sufficient to meet our operating requirements, we may, among other available options, pursue alternative financing arrangements or reduce expenditures as necessary to meet our cash requirements throughout 2016.

Recent Accounting Pronouncements

In March 2016, the the Financial Accounting Standards Board ("FASB") issued ASU 2016-09, “Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” ASU 2016-09 simplifies the accounting for share-based payment award transactions including: income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the requirements of ASU 2016-09 and have not yet determined its impact on our condensed consolidated financial statements.

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. Entities will have the option of using either a full retrospective approach or a modified approach to adopt the guidance in ASU 2014-09. We are currently evaluating the requirements of ASU 2015-14 and have not yet determined its impact on our condensed consolidated financial statements.

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, 2015. There have been no significant changes during the three months ended March 31, 2016 to the items that we disclosed as our critical accounting policies and estimates in Management's Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report on Form 10-K for the year ended December 31, 2015.

•	continued implementation of the Company's next-generation datacenter product; and


•	other statements that are not historical facts.

All statements that relate to future events or to our future performance are forward-looking statements. In some cases, forward-looking statements can be identified by terms such as “may,” “will,” “should,” “expect,” “plans,” “seeks,” “anticipate,”

“believe,” “estimate,” “predict,” “potential,” “continue,” “seek to continue,” “consider,” “intends,” or other comparable terminology. These forward-looking statements are made pursuant to safe-harbor provisions of the Private Securities Litigation Reform Act of 1995. These forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause our actual results or our industries’ actual results, levels of activity, performance or achievements to be materially different from any future results, levels of activity, performance or achievements expressed or implied by these forward-looking statements.

These factors include, among others, the continued implementation of the Company’s next-generation datacenter product, customer implementation of traffic management solutions, the outcome of product trials, the market success of customers' products and solutions, the development and transition of new products and solutions, the enhancement of existing products and solutions to meet customer needs and respond to emerging technological trends, the Company's dependence on certain customers and high degree of customer concentration, the Company's use of one contract manufacturer for a significant portion of the production of its products, including the success of transitioning contract manufacturing partners, matters affecting the software and embedded product industry, including changes in industry standards, changes in customer requirements and new product introductions, actions by regulatory authorities or other third parties, cash generation, changes in tariff and trade policies and other risks associated with foreign operations, fluctuations in currency exchange rates, key employee attrition, the ability of the Company to successfully complete any restructuring, acquisition or divestiture activities, risks relating to fluctuations in the Company's operating results, the uncertainty of revenues and profitability and the potential need to raise additional funding and other factors described in "Risk Factors" and elsewhere in our Annual Report on Form 10-K for the year ended December 31, 2015, as updated in the subsequent quarterly reports on Form 10-Q. Although forward-looking statements help provide additional information about us, investors should keep in mind that forward-looking statements are only predictions, at a point in time, and are inherently less reliable than historical information.

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

Item 3. Quantitative and Qualitative Disclosures about Market Risk

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

Foreign Currency Risk. We pay the expenses of our international operations in local currencies, namely, the Canadian Dollar, Euro, Chinese Yuan, Indian Rupee, 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, 2016 the total notional or contractual value of the contracts we held was $13.9 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 $1.4 million, decreasing our Indian Rupee hedge asset as of March 31, 2016, to a liability of $1.4 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 $1.3 million, increasing our hedge asset as of March 31, 2016 to $1.3 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, 2016, 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 ended December 31, 2015, 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 ended December 31, 2015 are not the only risks facing our Company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

Accounting Policies [Abstract]
Significant Accounting Policies	In March 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-09, “Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” ASU 2016-09 simplifies the accounting for share-based payment award transactions including: income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the requirements of ASU 2016-09 and have not yet determined its impact on the condensed consolidated financial statements. 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 have 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. Entities will have the option of using either a full retrospective approach or a modified approach to adopt the guidance in ASU 2014-09. The Company is currently evaluating the requirements of ASU 2015-14 and have not yet determined its impact on the condensed consolidated financial statements. 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, 2015 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, 2016 and for the three months ended March 31, 2016 and 2015 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, 2015. Certain prior year balances have been reclassified to conform to the current year’s presentation. Such reclassifications did not affect total cash flows, total net revenues, operating loss, net loss, total assets, total liabilities or shareholders’ equity. The financial information included herein reflects all normal recurring adjustments that are, in the opinion of management, necessary for a fair presentation of the results for interim periods.

Income Taxes	3 Months Ended
Income Taxes	Mar. 31, 2016
Income Tax Disclosure [Abstract]
Income Tax Disclosure	Income Taxes The Company's effective tax rate for the three months ended March 31, 2016 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, 2016. 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 $1.2 million at March 31, 2016 and December 31, 2015. 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 was approximately $3.7 million at March 31, 2016. The related interest and penalties were $0.7 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 2006, 2007 and 2010 through 2012. The examination is in various stages of appellate proceedings and all material uncertain tax positions associated with the examination have been taken into account in the ending balance of the unrecognized tax benefits at March 31, 2016. As of March 31, 2016, the Company is not under examination by tax authorities in any other jurisdictions.
