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 $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 $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 plans to adopt using the modified retrospective approach. 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 June 30, 2017 Total Level 1 Level 2 Level 3 Foreign currency forward contracts $ 713 — $ 713 — Fair Value Measurements as of December 31, 2016 Total Level 1 Level 2 Level 3 Foreign currency forward contracts $ 94 — $ 94 —

Short-term Debt [Abstract]
Short-term Debt	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 June 30, 2017, the Company entered into the Second Amendment to the Credit Agreement. The following takes into account the terms per the agreement as amended on June 30, 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 commencing on June 30, 2017 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 $8.0 million will be as follows: • When Availability is 70% or more, the interest rate is the prime rate (as published in Wall Street Journal) plus 0.75% ; • When Availability is 30% or more and less than 70% , the interest rate is the prime rate plus 1.00% ; and • When Availability is below 30% , the interest rate is the prime rate plus 1.25% . Commencing on June 30, 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 $8.0 million , 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 $0.4 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 in the second, third, and fourth quarter of fiscal year 2017 as follows: Quarter Ending Minimum Consolidated Adjusted EBITDA 6/30/17 $0 9/30/17 ($1,500,000) 12/31/17 $3,000,000 The Credit Agreement also provides limits for the add-back of certain restructuring costs on a trailing twelve month basis in the calculation of Consolidated Adjusted EBITDA as follows: Quarter Ending Restructuring Costs 6/30/17 $5,205,000 9/30/17 $9,550,000 12/31/17 $8,235,000 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 Credit 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 June 30, 2017 and December 31, 2016 , the Company had an outstanding balance of $45.0 million and $25.0 million under the Credit Agreement. Under the revolving credit facility, the Company may borrow up to $55.0 million at fiscal quarter ends. At June 30, 2017 , the Company utilized the quarter end availability feature to borrow beyond our ongoing available borrowing base of $31.4 million . At June 30, 2017 , the Company was in compliance with all covenants under the Amended Agreement.

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 $0.7 million and $0.3 million as of June 30, 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 June 30, 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): Six Months Ended June 30, 2017 2016 Warranty liability balance, beginning of the period $ 1,821 $ 2,553 Product warranty accruals 445 754 Utilization of accrual (672 ) (1,146 ) Warranty liability balance, end of the period $ 1,594 $ 2,161 At June 30, 2017 and December 31, 2016 , $1.3 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. Liquidity Outlook At June 30, 2017 , the Company's cash and cash equivalents amounte d to $46.2 million . The Company believes current cash and cash equivalents, cash expected to be generated from operations, available borrowings under the Silicon Valley Bank line of credit and availability under the $100.0 million unallocated shelf registration statement will satisfy the short and long-term expected working capital needs, capital expenditures, acquisitions, stock repurchases, and other liquidity requirements associated with present business operations. The Company believes current working capital, plus availability under the SVB line of credit, provides sufficient liquidity to operate the business at normal levels; however, to accelerate growth objectives, the Company may, among other available options, raise additional capital in the public or private markets or pursue alternative financing arrangements. If the Company becomes unable to comply with various covenants under the SVB line of credit due to expected declines in orders and shipments predominantly associated with DCEngine products and the timing of orders from large high-margin Software-Systems customers, without an amendment or waiver, the liquidity outlook could be adversely impacted. The Company continues to pursue a number of actions to improve cash position including (i) minimizing capital expenditures, (ii) effectively managing working capital, (iii) seeking amendments or waivers from lenders and (iv) improving cash flows from operations. These efforts continue in earnest and the Company is considering all available strategic alternatives and financing possibilities, including, without limitation, the incurrence of additional secured indebtedness and the exchange or refinancing of existing obligations.

Income Tax Disclosure [Abstract]
Income Tax Disclosure	Income Taxes The Company's effective tax rate for the three months ended June 30, 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 June 30, 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 June 30, 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 June 30, 2017 . The related interest and penalties were $0.8 million and $0.2 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 June 30, 2017 . The Company is currently under tax examination in Canada. The periods covered under examination in Canada are the Company's financial years 2013, 2014, 2015 and 2016. No examination adjustments have been proposed. As of June 30, 2017 , the Company is not under examination by tax authorities in any other jurisdictions.

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 years 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. For the period ended June 30, 2017, management assessed it was no longer probable that the 2016 and 2017 PRSU award targets would be achieved. Thus, no expense associated with these awards was recognized in the three months ended June 30, 2017. Stock-based compensation was recognized and allocated as follows (in thousands): Three Months Ended Six Months Ended June 30, June 30, 2017 2016 2017 2016 Cost of sales $ 40 $ 131 $ 137 $ 177 Research and development 113 285 343 438 Selling, general and administrative 385 776 1,212 1,265 Total $ 538 $ 1,192 $ 1,692 $ 1,880

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 June 30, 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 and six months ended June 30, 2017 and 2016 , the Company had no hedge ineffectiveness. During the three and six months ended June 30, 2017 the Company entered into 6 and 12 new foreign currency forward contracts, with total contractual values of $3.3 million and $6.9 million . During the three and six months ended June 30, 2016 , the Company entered into 9 and 21 new foreign currency contracts, with total contractual values of $3.1 million and $6.6 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 June 30, 2017 is as follows (in thousands): Contractual/ Notional Amount Condensed Consolidated Balance Sheet Classification Estimated Fair Value Type of Cash Flow Hedge Asset (Liability) Foreign currency forward exchange contracts $ 16,669 Other current assets $ 713 $ — A summary of the aggregate contractual or notional amounts, balance sheet location and estimated fair values of derivative financial instruments designated as cash flow hedges at December 31, 2016 is as follows (in thousands): Contractual/ Notional Amount Condensed Consolidated Balance Sheet Classification Estimated Fair Value Type of Cash Flow Hedge Asset (Liability) Foreign currency forward exchange contracts $ 16,166 Other current assets $ 94 $ — The following table summarizes the effect of derivative instruments on the consolidated financial statements as a loss (gain) as follows (in thousands): Three Months Ended Six Months Ended June 30, June 30, 2017 2016 2017 2016 Cost of sales $ (60 ) $ 75 $ (50 ) $ 183 Research and development (84 ) 122 (70 ) 295 Selling, general and administrative (28 ) 47 (23 ) 114 Total $ (172 ) $ 244 $ (143 ) $ 592 The following is a summary of changes to comprehensive income (loss) associated with the Company's hedging activities (in thousands): Three Months Ended Six Months Ended June 30, June 30, 2017 2016 2017 2016 Beginning balance of unrealized loss on forward exchange contracts $ (25 ) $ (685 ) $ (527 ) $ (819 ) Other comprehensive income (loss) before reclassifications 101 (162 ) 574 (376 ) Amounts reclassified from other comprehensive income (loss) (172 ) 244 (143 ) 592 Other comprehensive income (loss) (71 ) 82 431 216 Ending balance of unrealized loss on forward exchange contracts $ (96 ) $ (603 ) $ (96 ) $ (603 ) 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.
