Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	1. BASIS OF PRESENTATION The accompanying unaudited financial statements, consisting of the condensed consolidated balance sheet as of September 30, 2015, the condensed consolidated statements of operations for the three and nine months ended September 30, 2015 and 2014, the condensed consolidated statements of comprehensive income for the three and nine months ended September 30, 2015 and 2014, and the condensed consolidated statements of cash flows for the nine months ended September 30, 2015 and 2014, have been prepared in accordance with accounting principles generally accepted in the United States of America in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. In addition, the condensed consolidated balance sheet at December 31, 2014 has been derived from the audited consolidated financial statements as of that date. Accordingly, these condensed consolidated financial statements do not include all of the information and notes typically found in the audited consolidated financial statements and notes thereto included in the Annual Report on Form 10-K of Polycom, Inc. and its subsidiaries (the “Company”). In the opinion of management, the accompanying unaudited financial statements have been prepared on a basis consistent with the Company’s December 31, 2014 audited financial statements and all adjustments (consisting of normal recurring adjustments) considered necessary for a fair statement have been included. For further information, refer to the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reported period. Actual results could differ from those estimates and operating results for the three and nine months ended September 30, 2015 and are not necessarily indicative of the results that may be expected for the year ending December 31, 2015.

Recent Accounting Pronouncement

Accounting Policies [Abstract]
Recent Accounting Pronouncements	2. RECENT ACCOUNTING PRONOUNCEMENTS In July 2015, the FASB issued an accounting standard update which requires an entity measuring inventory other than last-in, first-out (LIFO) or the retail inventory method to measure inventory at the lower of cost and net realizable value. When evidence exists that the net realizable value of inventory is lower than its costs, the difference will be recognized as a loss in the statement of operations. The standard is effective for fiscal years beginning after December 15, 2016, and interim periods within fiscal years beginning after December 15, 2017. The Company is evaluating the impact of adopting this standard on its Consolidated Financial Statements and disclosures. In April 2015, the FASB issued an accounting standard update which provides guidance on whether a cloud computing arrangement includes a software license to a customer of such an arrangement. If a cloud computing arrangement includes a software license, a customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses, otherwise the customer should account for the arrangement as a service contract. The standard is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted. The standard can be applied prospectively to all arrangements entered into or materially modified after the effective date, or retrospectively. The Company is evaluating the impact of adopting this standard on its Consolidated Financial Statements and disclosures. In April 2015, the FASB issued an accounting standard update which requires an entity to present debt issuance costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. Amortization of the costs will continue to be reported as interest expense. The standard is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted. The standard will be applied retrospectively to each prior period presented. The accounting standard update is a change in balance sheet presentation only and is not expected to have a material impact on the Company’s Consolidated Financial Statements. In May 2014, the FASB an accounting standard update which promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services Companies may use either a full retrospective or a modified retrospective approach to adopt the standard. The Company is evaluating the potential effects of the adoption of this standard on its Consolidated Financial Statements.

Discontinued Operations

Discontinued Operations And Disposal Groups [Abstract]
Discontinued Operations	3. DISCONTINUED OPERATIONS On December 4, 2012, the Company completed the disposition of the net assets of its enterprise wireless voice solutions (“EWS”) business to Mobile Devices Holdings, LLC, a Delaware limited liability corporation. Additional cash consideration of up to $25.0 million is payable to Polycom over the next two years subject to certain conditions, including meeting certain agreed-upon EBITDA-based milestones for the fiscal years ending December 31, 2015 and 2016. These conditions were not met for the fiscal years ended December 31, 2013 and 2014. Such additional cash consideration will be accounted for as a gain on sale of discontinued operations, net of taxes, when it is realized or realizable. For the nine months ended September 30, 2015 and 2014, there were no realized gains on sale of discontinued operations.

Accounts Receivable Financing

Accounts Receivable Financing	9 Months Ended

Receivables [Abstract]
Accounts Receivable Financing	4. ACCOUNTS RECEIVABLE FINANCING The Company has a financing agreement with an unrelated third party financing company (the “Financing Agreement”) whereby the Company offers distributors and resellers’ direct or indirect financing on their purchases of the Company’s products and services. In return, the Company agrees to pay the financing company a fee based on a defined percentage of the transaction amount financed. In certain instances, these financing arrangements result in a transfer of its receivables, without recourse, to the financing company. If the transaction meets the applicable criteria under Accounting Standards Codification (“ASC”) 860 and is accounted for as a sale of financial assets, the accounts receivable are excluded from the balance sheet upon the third party financing company’s payment remittance to the Company. In certain legal jurisdictions, the arrangement fees that involve maintenance services or products bundled with maintenance at one price do not qualify as a sale of financial assets in accordance with the authoritative guidance. Accordingly, accounts receivable related to these arrangements are accounted for as a secured borrowing in accordance with ASC 860, and the Company records a liability for any cash received, while maintaining the associated accounts receivable balance until the distributor or reseller remits payment to the third-party financing company. In the three and nine months ended September 30, 2015, total transactions entered into pursuant to the terms of the Financing Agreement were approximately $55.6 million and $173.1 million, respectively, of which $33.8 million and $106.8 million, respectively, were related to the transfer of the financial assets arrangement. In the three and nine months ended September 30, 2014, total transactions entered were approximately $48.8 million and $132.6 million, respectively, of which $29.4 million and $98.1 million, respectively, were related to the transfer of the financial assets arrangement. The financing of these receivables accelerated the collection of the Company’s cash and reduced its credit exposure. The amount due from the financing company as of September 30, 2015 and December 31, 2014 was approximately $32.9 million and $28.5 million, respectively, of which $18.5 million and $20.2 million, respectively, was related to the accounts receivable transferred, and is included in “Trade receivables” in the Company’s condensed consolidated balance sheets. Fees incurred pursuant to the Financing Agreement were approximately $0.8 million and $0.7 million for the three months ended September 30, 2015 and 2014, respectively, and were approximately $2.5 million and $1.8 million for the nine months ended September 30, 2015 and 2014 respectively. Those fees were recorded as reductions to revenues.

Consequently, this trade name is not amortized but is reviewed for impairment annually or sooner when indicators of potential impairment exist. The following table summarizes the amortization expenses recorded in the following periods (in thousands): Three Months Ended Nine Months Ended September 30, 2015 September 30, 2014 September 30, 2015 September 30, 2014 Amortization of purchased intangibles in revenues $ 13 $ 19 $ 51 $ 57 Amortization of purchased intangibles in cost of product revenues 99 732 856 2,304 Amortization of purchased intangibles in operating expenses 2,399 2,435 7,233 7,363 Total amortization expenses of purchased intangibles $ 2,511 $ 3,186 $ 8,140 $ 9,724 Amortization of purchased intangibles is not allocated to the Company’s segments. The estimated future amortization expense as of September 30, 2015 is as follows (in thousands): Year ending December 31, Amount Remainder of 2015 $ 2,356 2016 8,484 2017 4,669 Total $ 15,509 In the nine months ended September 30, 2015 and 2014, the Company capitalized approximately $4.2 million and $3.2 million of software development costs, respectively, for internally developed software products to be marketed and sold to customers after the point that technological feasibility has been reached and before the products are available for general release. The capitalized costs are being amortized over the estimated product useful life, generally three years, beginning when the products are available for general release. Management expects that the capitalized software development costs are recoverable from future gross profits generated by these products and services.

Restructuring And Related Activities [Abstract]
Restructuring Costs	6. RESTRUCTURING COSTS The Company recorded $0.2 million of net restructuring charges and $2.6 million of net restructuring credits during the three months ended September 30, 2015 and 2014, respectively. The Company recorded $0.6 million and $36.9 million of net restructuring charges during the nine months ended September 30, 2015 and 2014, respectively. The restructuring charges during the three and nine months ended September 30, 2015 were primarily due to accruals for severance payments for certain employees who were notified during this period, and adjustments related to changes in assumptions used in its facilities-related restructuring estimates. Restructuring costs primarily related to certain actions announced in January 2014 which included reduction of approximately six percent of the global workforce and the reduction or elimination of certain leased facilities, and certain discrete follow-on actions that were not material. These actions were designed to better align expenses to the Company’s revenue and gross margin profile and position the Company for improved operating performance. The Company has recorded a cumulative amount of $40.9 million in restructuring costs (net of adjustments related to the assumptions used in the estimate of the related liabilities reserves) as of September 30, 2015 in connection with these actions, and does not expect any remaining charges to be material. The following table summarizes the changes in the Company’s restructuring reserves during the nine months ended September 30, 2015 (in thousands): Severance/Other Facilities Total Balance at December 31, 2014 $ 664 $ 40,909 $ 41,573 Additions to the reserve, net 4,590 (5,266 ) (676 ) Interest accretion — 1,284 1,284 Non-cash adjustments — (570 ) (570 ) Cash payments (4,374 ) (16,126 ) (20,500 ) Balance at September 30, 2015 $ 880 $ 20,231 $ 21,111 As of September 30, 2015, the restructuring reserve was primarily comprised of facilities-related liabilities. At the time the reserve is initially set up, the Company calculates the fair value of its facilities-related liabilities based on the discounted future lease payments less sublease assumptions. This fair value measurement is classified as a Level 3 measurement under ASC 820. The key assumptions used in the valuation model include discount rates, cash flow projections, and estimated sublease income. These assumptions involve significant judgment, are based on management’s estimate of current and forecasted market conditions and are sensitive and susceptible to change.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	8. COMMITMENTS AND CONTINGENCIES Litigation and SEC Investigation From time to time, the Company is involved in claims and legal proceedings that arise in the ordinary course of business. The Company expects that the number and significance of these matters will increase as its business expands. In particular, the Company faces an increasing number of patent and other intellectual property claims as the number of products and competitors in Polycom’s industry grows and the functionality of video, voice, data and web conferencing products overlap. Any claims or proceedings against the Company, whether meritorious or not, could be time consuming, result in costly litigation, require significant amounts of management time, result in the diversion of significant operational resources, or require the Company to enter into royalty or licensing agreements which, if required, may not be available on terms favorable to the Company or at all. If management believes that a loss arising from these matters is probable and can be reasonably estimated, the Company will record a reserve for the loss. As additional information becomes available, any potential liability related to these matters is assessed and the estimates revised. Based on currently available information, management does not believe that the ultimate outcomes of these unresolved matters, individually and in the aggregate, are likely to have a material adverse effect on the Company’s financial position, liquidity or results of operations. However, litigation is subject to inherent uncertainties, and the Company’s view of these matters may change in the future. Were an unfavorable outcome to occur, there exists the possibility of a material adverse impact on the Company’s financial position and results of operations or liquidity for the period in which the unfavorable outcome occurs or becomes probable, and potentially in future periods. On July 23, 2013, the Company announced that Andrew M. Miller had resigned from the positions of Chief Executive Officer and President of Polycom and from Polycom’s Board of Directors. The Company disclosed that Mr. Miller’s resignation came after a review by the Audit Committee of certain expense submissions by Mr. Miller, where the Audit Committee found certain irregularities in the submissions, for which Mr. Miller had accepted responsibility. Specifically, the Audit Committee determined that Mr. Miller improperly submitted personal expenses to Polycom for payment as business expenses and, in doing so, submitted to Polycom false information about the nature and purpose of expenses. SEC Investigation . As previously disclosed, the Company has been cooperating with the Enforcement Staff of the Securities and Exchange Commission (“SEC”) in connection with its investigation focused on Mr. Miller's expenses and his resignation. On March 31, 2015 the Company entered into a settlement with the SEC. Under the terms of the settlement in which the Company did not admit or deny the SEC’s findings, the Company paid $750,000 in a civil penalty, and agreed not to commit or cause any violations of certain provisions of the Securities Exchange Act of 1934 and related rules. Class Action Lawsuit . On July 26, 2013, a purported shareholder class action, initially captioned ., Case No. 3:13-cv-03476-SC, and presently captioned , ., Case No. 3:13-cv-03476-SC, was filed in the United States District Court for the Northern District of California against the Company and certain of its current and former officers and directors. On December 13, 2013, the Court appointed a lead plaintiff and approved lead and liaison counsel. On February 24, 2014, the lead plaintiff filed a first amended complaint. The amended complaint alleged that, between January 20, 2011 and July 23, 2013, the Company issued materially false and misleading statements or failed to disclose information regarding the Company’s business, operational and compliance policies, including with respect to its former Chief Executive Officer’s expense submissions and the Company’s internal controls. The lawsuit further alleged that the Company’s financial statements were materially false and misleading. The amended complaint alleged violations of the federal securities laws and sought unspecified compensatory damages and other relief. On April 3, 2015, the Court dismissed all claims against Polycom and granted plaintiffs leave to amend. The lead plaintiff filed a second complaint on May 4, 2015. Polycom and the individual defendants moved to dismiss the second amended complaint on June 26, 2015. Those motions are pending. At this time, the Company is unable to estimate any range of reasonably possible loss relating to the securities class action lawsuit. Derivative Lawsuits . On August 21, 2013 and October 16, 2013, two purported shareholder derivative suits, captioned , Case No. 5:13-cv-03880, and ., Case No. 5:13-cv-04810, respectively, were filed in the United States District Court for the Northern District of California against certain of the Company’s current and former officers and directors. On October 31, 2013, these two federal derivative actions were consolidated into , Lead Case No. 3:13-cv-03880. On January 13, 2015, the Court dismissed the operative complaint and granted plaintiffs leave to amend. On April 3, 2015, the Court approved a stipulation dismissing the action with prejudice and entering judgment in favor of defendants. On November 22, 2013 and December 13, 2013, two purported shareholder derivative suits, captioned Ware v. Miller, et al. Clem v. Miller, et al In re Polycom, Inc. Derivative Shareholder Litigation The California state consolidated derivative lawsuit purports to assert claims on behalf of the Company, which is named as a nominal defendant in the actions. The original California state complaints allege claims for breach of fiduciary duty, unjust enrichment, and corporate waste, and allege certain defendants failed to maintain adequate internal controls and issued, or authorized the issuance of, materially false and misleading statements, including with respect to the Company’s former Chief Executive Officer’s expense submissions and the Company’s internal controls. The complaints further allege that certain defendants approved an unjustified separation agreement and caused the Company to repurchase its own stock at artificially inflated prices. The complaints seek unspecified compensatory damages, corporate governance reforms, and other relief. At this time, the Company is unable to estimate any range of reasonably possible loss relating to the derivative actions. Officer and Director Indemnifications As permitted or required under Delaware law and to the maximum extent allowable under that law, the Company has certain obligations to indemnify its current and former officers and directors for certain events or occurrences while the officer or director is, or was serving, at the Company’s request in such capacity. The maximum potential amount of future payments the Company could be required to make under these indemnification obligations is unlimited; however, the Company has a director and officer insurance policy that mitigates the Company’s exposure and enables the Company to recover a portion of any future amounts paid. As a result of the Company’s insurance policy coverage, the Company believes the estimated fair value of these indemnification obligations is not material. Other Indemnifications As is customary in the Company’s industry, as provided for in local law in the United States, and other jurisdictions, the Company’s standard contracts provide remedies to its customers, such as defense, settlement, or payment of judgment for intellectual property claims related to the use of its products. From time to time, the Company indemnifies customers against combinations of loss, expense, or liability arising from various trigger events related to the sale and the use of its products and services. In addition, from time to time, the Company also provides protection to customers against claims related to undiscovered liabilities, additional product liability or environmental obligations.

Debt Disclosure [Abstract]
Debt	9. DEBT In September 2013, the Company entered into a Credit Agreement (the “Credit Agreement”) that provides for a $250.0 million term loan (the “Term Loan”) maturing on September 13, 2018 (the “Maturity Date”), which bears interest at the Company’s option at either a base rate plus a spread of 0.50% to 1.00%, or a reserve adjusted LIBOR rate plus a spread of 1.50% to 2.00% based on the Company’s consolidated leverage ratio for the preceding four fiscal quarters. The Company entered into the Credit Agreement in conjunction with and for purposes of funding purchases of the Company’s common stock pursuant to a $250.0 million modified “Dutch Auction” self-tender offer announced in September 2013. The Term Loan is payable in quarterly installments of principal equal to $1.6 million which began on December 31, 2013, with the remaining outstanding principal amount of the Term Loan being due and payable on the Maturity Date. The Company may prepay the Term Loan, in whole or in part, at any time without premium or penalty. Amounts repaid or prepaid may not be reborrowed. The Term Loan is secured by substantially all the assets of the Company and of certain domestic subsidiaries of the Company that are guarantors under the Credit Agreement, subject to certain exceptions and limitations. The Credit Agreement contains customary affirmative and negative covenants, and financial covenants consisting of a consolidated fixed charge coverage ratio and a consolidated secured leverage ratio. The Company was in compliance with these covenants as of September 30, 2015. The Credit Agreement also includes customary events of default, the occurrence of which could result in the acceleration of the obligations under the Credit Agreement. Under certain circumstances, a default interest rate will apply on all obligations during the existence of an event of default under the Credit Agreement at a per annum rate equal to 2.00% above the applicable interest rate for any overdue principal and 2.00% above the rate applicable for base rate loans for any other overdue amounts. At September 30, 2015, the weighted average interest rate on the Term Loan was 2.23%, the accrued interest on the Term Loan was $0.6 million, and the current and non-current portion of the outstanding Term Loan was $6.3 million and $231.3 million, respectively. The following table sets forth total interest expense recognized on the Term Loan (in thousands): Three Months Ended Nine Months Ended September 30, 2015 September 30, 2014 September 30, 2015 September 30, 2014 Contractual interest expense $ 1,328 $ 1,233 $ 3,878 $ 3,687 Amortization of debt issuance costs 133 133 399 400 Total $ 1,461 $ 1,366 $ 4,277 $ 4,087

There have been no transfers between Level 1 and Level 2 in the three and nine months ended September 30, 2015 and 2014. There were no investments classified as Level 3 as of September 30, 2015 and December 31, 2014. In addition, the Company has facilities-related liabilities related to restructuring which were calculated based on the discounted future lease payments less sublease assumptions. This non-recurring fair value measurement is classified as a Level 3 measurement under ASC 820. See Note 6 for further details. The fair value of the Company’s Term Loan under its Credit Agreement is measured using Level 2 inputs as the borrowings are not actively traded and have a variable interest rate structure based upon market rates currently available to the Company for debt with similar terms and maturities. The Company has elected not to record its Term Loan at fair value, but has measured it at fair value for disclosure purposes. At September 30, 2015 and December 31, 2014, the estimated fair value of the Term Loan was approximately $232.8. million and $234.9 million, respectively, using observable market inputs.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Foreign Currency Derivatives	12. FOREIGN CURRENCY DERIVATIVES The Company maintains a foreign currency risk management program that is designed to reduce the volatility of the Company’s economic value from the effects of unanticipated currency fluctuations. International operations generate both revenues and costs denominated in foreign currencies. The Company’s policy is to hedge significant foreign currency revenues and costs to improve margin visibility and reduce earnings volatility associated with unexpected changes in currency. Non-Designated Hedges The Company hedges its net foreign currency monetary assets and liabilities primarily resulting from foreign currency denominated receivables and payables with foreign exchange forward contracts to reduce the risk that the Company’s earnings and cash flows will be adversely affected by changes in foreign currency exchange rates. These derivative instruments are carried at fair value with changes in the fair value recorded in “Interest and other income (expense), net” on the condensed consolidated statements of operations. These derivative instruments do not subject the Company to material balance sheet risk due to exchange rate movements because gains and losses on these derivatives are intended to offset remeasurement gains and losses on the hedged assets and liabilities. The Company executes non-designated foreign exchange forward contracts primarily denominated in Euros, British Pounds, Israeli Shekels, Brazilian Reals, Chinese Yuan, Japanese Yen and Mexican Pesos. The following table summarizes the Company’s notional position by currency, and approximate U.S. dollar equivalent of the outstanding non-designated hedges at September 30, 2015 (in thousands): Original Maturities of 360 Days or Less Original Maturities of Greater than 360 Days Foreign Currency USD Equivalent Positions Foreign Currency USD Equivalent Positions Brazilian Real 23,029 $ 5,797 Buy — $ — — Brazilian Real 43,600 $ 11,381 Sell — $ — — Chinese Yuan — $ — — 44,971 $ 7,026 Buy Chinese Yuan 42,574 $ 6,639 Sell — $ — — Euro 9,410 $ 10,512 Buy 9,063 $ 11,163 Buy Euro 19,469 $ 21,795 Sell 30,575 $ 37,662 Sell British Pound 1,004 $ 1,535 Buy 11,980 $ 18,657 Buy British Pound 720 $ 1,101 Sell 14,502 $ 22,586 Sell Israeli Shekel 21,905 $ 5,577 Buy 37,500 $ 9,653 Buy Israeli Shekel 53,017 $ 13,493 Sell — $ — — Japanese Yen 108,585 $ 907 Sell — $ — — Mexican Peso 15,802 $ 932 Buy — $ — — Mexican Peso 34,459 $ 2,034 Sell — $ — — The following table shows the effect of the Company’s non-designated hedges in the condensed consolidated statements of operations (in thousands): Derivatives Not Designated as Hedging Instruments Location of Gain or (Loss) Recognized in Income on Derivative Amount of Gain or (Loss) Recognized in Income on Derivative Three Months Ended September 30, 2015 September 30, 2014 Foreign exchange contracts Interest and other income (expense), net $ 1,165 $ 3,991 Nine Months Ended September 30, 2015 September 30, 2014 Foreign exchange contracts Interest and other income (expense), net $ 4,782 $ 4,290 Cash Flow Hedges The Company’s foreign exchange risk management program objective is to reduce volatility in the Company’s economic value from unanticipated foreign currency fluctuations. The Company designates forward contracts as cash flow hedges of foreign currency revenues and expenses, primarily the Chinese Yuan, Euros, British Pounds and Israeli Shekels. All foreign exchange contracts are carried at fair value on the condensed consolidated balance sheets and the maximum duration of foreign exchange forward contracts does not exceed 13 months. Speculation is prohibited by policy.

As of September 30, 2015, the Company estimated that all values reported in accumulated other comprehensive income will be reclassified to income within the next twelve months. In the event the underlying forecasted transaction does not occur, or it becomes probable that it will not occur, the related hedge gains and losses on the cash flow hedge would be immediately reclassified to “Interest and other income (expense), net” on the condensed consolidated statements of operations. For the nine months ended September 30, 2015 and 2014, there were no such gains or losses. The estimates of fair value are based on applicable and commonly quoted prices and prevailing financial market information as of September 30, 2015 and December 31, 2014. See Note 11 for additional information on the fair value measurements for all financial assets and liabilities, including derivative assets and derivative liabilities that are measured at fair value in the condensed consolidated financial statements on a recurring basis. The following table shows the Company’s derivative instruments measured at gross fair value as reflected in the condensed consolidated balance sheets (in thousands): Fair Value of Derivatives Designated as Hedge Instruments Fair Value of Derivatives Not Designated as Hedge Instruments September 30, 2015 December 31, 2014 September 30, 2015 December 31, 2014 Derivative assets (a): Foreign exchange contracts $ 1,641 $ 5,501 $ 4,668 $ 8,841 Derivative liabilities (b): Foreign exchange contracts $ 1,646 $ 4,041 $ 1,725 $ 4,134 (a) All derivative assets are recorded in “Prepaid and other current assets” in the condensed consolidated balance sheets. (b) All derivative liabilities are recorded in “Other accrued liabilities” in the condensed consolidated balance sheets. Offsetting Derivative Assets and Liabilities The Company has entered into master netting arrangements with each of its derivative counterparties. These arrangements afford the right to net derivative assets against liabilities with the same counterparty. Under certain default provisions, the Company has the right to set off any other amounts payable to the payee whether or not arising under this agreement. As a result of the netting provisions, the Company’s maximum amount of loss under derivative transactions due to credit risk is limited to the net amounts due from the counterparties under the derivative contracts. Although netting is permitted, it is currently the Company’s policy and practice to record all derivative assets and liabilities on a gross basis in the condensed consolidated balance sheets.

Equity [Abstract]
Stockholders' Equity	13. STOCKHOLDERS’ EQUITY Share Repurchase Program From time to time, the Company’s Board of Directors has approved plans under which the Company may at its discretion purchase shares of its common stock in the open market or via privately negotiated transactions. In July 2014, the Company announced that its Board of Directors had approved a share repurchase plan (the “2014 repurchase plan”) under which the Company may at its discretion purchase shares in the open market with an aggregate value of up to $200.0 million. The Company expects to execute this new authorization through the end of June 2016 and to fund the share repurchases through cash on hand and future cash flow from operations. During the three and nine months ended September 30, 2015, the Company purchased approximately 2.2 million and 7.0 million shares of common stock, respectively, in the open market for approximately $25.0 million and $90.0 million, respectively. During the three months ended September 30, 2014, the Company purchased approximately 1.9 million shares of common stock in the open market for $25 million. During the six months ended June 30, 2014, the Company did not purchase any shares of common stock in the open market. However, the Company received 1.5 million shares in June 2014 under its accelerated share repurchase program as discussed below. The purchase price for the shares of the Company’s stock repurchased is recorded as a reduction to stockholders’ equity. The excess of the cost of treasury stock that is retired over its par value and the portion allocated to additional paid-in capital based on the calculated average price in equity is recorded as a charge to retained earnings. The repurchased shares of common stock have been retired and reclassified as authorized and unissued shares. As of September 30, 2015, the Company had a remaining authorization to purchase up to an additional $60.0 million of shares in the open market under the 2014 repurchase plan. Accelerated Share Repurchase Agreements On December 4, 2013, the Company entered into separate accelerated share repurchase (“ASR”) agreements with two financial institutions to repurchase an aggregate of $114.6 million of common stock as part of the last phase of the Company’s $400.0 million Return of Capital Program. Under the terms of the ASR agreements, the Company paid an aggregate $114.6 million of cash and received an initial delivery of approximately 8.0 million shares in December 2013. The ASR contracts were settled in June 2014, whereby the Company received an additional 1.5 million shares upon settlement. The aggregate 9.5 million shares ultimately purchased under the ASR program was determined based on the Company’s volume-weighted average stock price (“VWAP”) less an agreed upon discount during the term of the transactions. Total shares repurchased were immediately retired upon delivery and accounted for as a reduction to stockholders’ equity. The costs associated with the ASR transactions were recorded as an adjustment to the stockholders’ equity. Additionally, the Company accounted for the ASR transactions as repurchases of common stock for the purpose of calculating its earnings per share when the shares were received. Accumulated Other Comprehensive Income The following table summarizes the changes in accumulated other comprehensive income, net of tax, by component (in thousands). The tax effects were not shown separately, as the impacts were not material.

Stock Options There were no stock options granted in the nine months ended September 30, 2015 and 2014. Performance Shares and Restricted Stock Units During the nine months ended September 30, 2015 and 2014, the Company granted 972,112 and 659,416 performance shares to certain employees and executives, at a weighted average fair value of $14.04 and $13.81 per share, respectively. The 2015 and 2014 grants are generally divided evenly over three annual performance periods commencing with calendar year 2015 and 2014, respectively, and will vest on the first, second and third anniversary of the grant date. During the nine months ended September 30, 2015 and 2014, the Company granted 3,058,643 and 2,847,979 restricted stock units to certain employees, at a weighted average fair value of $13.53 and $12.96 per share, respectively. During the nine months ended September 30, 2015 and 2014, the Company granted 135,000 and 140,000, restricted stock units to non-employee directors at a weighted average fair value of $12.90 and $12.87 per share, respectively. Employee Stock Purchase Plan During the nine months ended September 30, 2015 and 2014, 2,150,586 and 2,944,069 shares were purchased under the Company’s employee stock purchase plan (“ESPP”), respectively. As of September 30, 2015, there were 9,164,481 shares available to be issued under the ESPP. Valuation Assumptions For purchase rights granted pursuant to the ESPP, the estimated fair value per share of employee stock purchase rights for the two-year offering period commencing on August 3, 2015 ranged from $2.56 to $3.45, compared to the estimated fair value per share from $2.80 to $4.10 for the two-year offering period commencing on August 1, 2014. The estimated fair value per share of employee stock purchase rights for the two year offering period commencing on February 2, 2015 ranged from $3.09 to $4.27, compared to the estimated fair value per share from $2.82 to $4.48 for the two-year offering period commencing on February 3, 2014. The fair value of each employee stock purchase right grant is estimated on the date of grant using the Black-Scholes option valuation model and is recognized as expense using the graded vesting method using the following assumptions: Three Months Ended Nine Months Ended September 30, 2015 September 30, 2014 September 30, 2015 September 30, 2014 Expected volatility 28.60-29.76% 26.47-32.18% 28.08-30.73% 26.47-42.11% Risk-free interest rate 0.17-0.68% 0.05-0.47% 0.07-0.68% 0.05-0.47% Expected dividends 0.0% 0.0% 0.0% 0.0% Expected life (years) 0.5-1.99 0.5-2.0 0.49-2.0 0.5-2.0 The Company computed its expected volatility assumption based on blended volatility (50% historical volatility and 50% implied volatility). The selection of the blended volatility assumption was based upon the Company’s assessment that blended volatility is more representative of the Company’s future stock price trends as it weighs in the longer term historical volatility with the near term future implied volatility. The risk-free interest rate assumption is based upon observed interest rates appropriate for the expected life of the Company’s employee stock purchases. The dividend yield assumption is based on the Company’s history of not paying dividends and no future expectation of dividend payouts. The expected life of employee stock purchase rights represents the contractual terms of the underlying program.

Segment Reporting [Abstract]
Business Segment Information	16. BUSINESS SEGMENT INFORMATION The Company conducts its business globally and is managed geographically in three segments: (1) Americas, which consists of North America and Caribbean and Latin America (“CALA”) reporting units, (2) Europe, Middle East and Africa (“EMEA”) and (3) Asia Pacific (“APAC”). The segments are determined in accordance with how management views and evaluates the Company’s business and allocates its resources, and are based on the criteria as outlined in the authoritative guidance. Segment Revenue and Profit Segment revenues consist of product and service revenues. Product revenues are attributed to a segment based on the ordering location of the customer. For internal reporting purposes and determination of segment contribution margins, geographic segment product revenues may differ slightly from actual geographic revenues due to internal revenue allocations between the Company’s segments. Service revenues are generally attributed to a segment based on the end-user’s location where services are performed. A significant portion of each segment’s expenses arises from shared services and infrastructure that Polycom has historically allocated to the segments in order to realize economies of scale and to use resources efficiently. Segment contribution margin includes all geographic segment revenues less the related cost of sales and direct revenues and marketing expenses. Cost of revenues consists of the standard cost of revenues and does not include items such as warranty expense, royalties, and the allocation of overhead expenses, including facilities and IT costs, as well as stock-based compensation costs and amortization of purchased intangible assets. Management allocates some infrastructure costs, such as facilities and IT costs, in determining segment contribution margins. Contribution margin is used, in part, to evaluate the performance of, and allocate resources to, each of the segments. Certain operating expenses are not allocated to segments because they are separately managed at the corporate level. These unallocated costs include corporate manufacturing costs, sales and marketing costs other than direct sales and marketing expenses, research and development expenses, general and administrative costs, such as legal and accounting, stock-based compensation costs, transaction-related costs, amortization of purchased intangibles, restructuring costs and interest and other income (expense), net. Segment Data The results of the reportable segments are derived directly from Polycom’s management reporting system. Management measures the performance of each segment based on several metrics, including contribution margin as defined above. Asset data, with the exception of gross accounts receivable, is not reviewed by management at the segment level. Financial information for each reportable geographical segment as of September 30, 2015 and December 31, 2014 and for the three and nine months ended September 30, 2015 and 2014, based on the Company’s internal management reporting system and as utilized by the Company’s Chief Operating Decision Maker (“CODM”), its Chief Executive Officer, is as follows (in thousands): Americas EMEA APAC Total For the three months ended September 30, 2015: Revenue $ 148,157 $ 77,274 $ 77,679 $ 303,110 % of total revenue 49 % 25 % 26 % 100 % Contribution margin $ 55,032 $ 32,260 $ 37,392 $ 124,684 % of segment revenue 37 % 42 % 48 % 41 % For the three months ended September 30, 2014: Revenue $ 166,354 $ 83,995 $ 85,337 $ 335,686 % of total revenue 50 % 25 % 25 % 100 % Contribution margin $ 66,993 $ 36,686 $ 35,965 $ 139,644 % of segment revenue 40 % 44 % 42 % 42 % For the nine months ended September 30, 2015: Revenue $ 463,844 $ 251,988 $ 234,553 $ 950,385 % of total revenue 49 % 26 % 25 % 100 % Contribution margin $ 176,648 $ 107,024 $ 109,480 $ 393,152 % of segment revenue 38 % 42 % 47 % 41 % For the nine months ended September 30, 2014: Revenue $ 497,229 $ 256,099 $ 242,901 $ 996,229 % of total revenue 50 % 26 % 24 % 100 % Contribution margin $ 206,121 $ 109,460 $ 100,985 $ 416,566 % of segment revenue 41 % 43 % 42 % 42 % As of September 30, 2015: Gross accounts receivable $ 99,248 $ 53,673 $ 60,333 $ 213,254 % of total gross accounts receivable 47 % 25 % 28 % 100 % As of December 31, 2014: Gross accounts receivable $ 88,316 $ 62,540 $ 63,808 $ 214,664 % of total gross accounts receivable 41 % 29 % 30 % 100 % During the three months ended September 30, 2015, two customers, ScanSource Communications (“ScanSource”) and Westcon Group Inc (“Westcon”), accounted for 19% and 10%, respectively, of the Company’s revenues.

INCOME TAXES The following table presents the income tax expense and the effective tax rates (in thousands): Three Months Ended Nine Months Ended September 30, 2015 September 30, 2014 September 30, 2015 September 30, 2014 Provision for income taxes $ 5,757 $ 1,817 $ 17,206 $ 54 Effective tax rate 29.8 % 9.7 % 24.0 % 0.2 % The Company is subject to income taxes in the U.S. and numerous foreign jurisdictions, and the effective tax rate reflects the applicable tax rates in effect in the various tax jurisdictions around the world where income is earned. The effective tax rate for the three and nine months ended September 30, 2015 and 2014 differs from the U.S. federal statutory rate of 35% primarily due to impacts associated with proportional earnings from the Company’s operations in lower tax jurisdictions, recurring permanent adjustments, and discrete items recorded during the period presented. A significant portion of pretax income is earned and taxed outside the U.S. The impacts on the tax provision due to lower statutory tax rates in foreign jurisdictions were benefits of approximately $4.1 million and $15.1 million for the three and nine months ended September 30, 2015, respectively, and benefits of approximately $7.2 million and $8.3 million for the three and nine months ended September 30, 2014, respectively. As noted above, the effective income tax rate can be impacted each period by discrete factors or events. For the three and nine months ended September 30, 2015 and 2014, discrete benefits of $0.2 million and $0.9 million and $0.7 million and $2.2 million, respectively, were recorded for tax benefits realized on disqualifying dispositions of stock from the Company’s employee stock purchase plan. For the three months ended September 30, 2015 and 2014, the tax rate included discrete benefits of $0.9 million and $0.8 million, respectively, related to the expiration of certain statutes. For the three months ended September 30, 2015, a discrete charge of $2.2 million for a valuation allowance was recorded on deferred taxes in a foreign jurisdiction and for the nine months ended September 30, 2014, a $0.9 million discrete tax benefit was recorded related to stock-based compensation expense adjustments for certain terminated employees . As of September 30, 2015, the amount of gross unrecognized tax benefits was $19.7 million, all of which would affect the Company’s effective tax rate if realized. The Company recognizes interest income and interest expense and penalties on tax overpayments and underpayments within income tax expense. As of September 30, 2015 and December 31, 2014, the Company had approximately $1.5 million and $1.6 million, respectively, of accrued interest and penalties related to uncertain tax positions. The Company anticipates that, except for $1.3 million in uncertain tax positions that may be reduced related to the lapse of various statutes of limitation, there will be no material changes in uncertain tax positions in the next 12 months. The Company is a U.S. based multinational company subject to tax in multiple U.S. and foreign tax jurisdictions, and has entered into agreements with the local governments in certain foreign jurisdictions where it has significant operations to provide it with favorable tax rates in those jurisdictions if certain criteria are met. The tax benefit realized from favorable tax rates for the three and nine months ended September 30, 2015 was estimated to be $3.2 million ($0.02 per share). Favorable tax rates for the three and nine months ended September 30, 2014 were not material in the aggregate and did not have a material impact on earnings per share. The Company regularly assesses the ability to realize deferred tax assets recorded in all entities based upon the weight of available evidence, including such factors as recent earnings history and expected future taxable income. If the Company’s future business profits do not support the realization of deferred tax assets, an addition to the valuation allowance could be recorded. In the event that the Company changes its determination as to the amount of deferred tax assets that can be realized, the Company will adjust its valuation allowance with a corresponding impact to the provision for income taxes in the period in which such determination is made. On July 27, 2015, the United States Tax Court (the “Court”) issued a taxpayer-favorable opinion with respect to Altera Corporation (“Altera”)’s litigation with the Internal Revenue Service (“IRS”). The litigation relates to the treatment of share-based compensation expense in an inter-company cost-sharing arrangement with the taxpayer’s foreign subsidiary for fiscal years 2004 through 2007. In its opinion, the Court accepted Altera’s position of excluding share-based compensation in its cost sharing arrangement and concluded that the related IRS Regulations were invalid. The Court has yet to issue its decision, the timing of which is uncertain. Once the Court’s decision is issued, the IRS has 90 days to decide whether to appeal the Court’s decision. As such, no adjustment to the consolidated financial statement is recorded at this time. The Company is monitoring this case for any material impact to our consolidated financial statement and its potential favorable implications to the Company’s cost-sharing arrangement.
