ORGANIZATION AND OPERATIONS	'
	BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Description of Business
	Avid Technology, Inc. (“Avid” or the “Company”) provides technology solutions that enable the creation and monetization of audio and video content. Specifically, the Company develops, markets, sells and supports software and hardware for digital media content production, management and distribution. Digital media are video, audio or graphic elements in which the image, sound or picture is recorded and stored as digital values, as opposed to analog or tape-based signals. The Company’s products are used in production and post-production facilities; film studios; network, affiliate, independent and cable television stations; recording studios; live-sound performance venues; advertising agencies; government and educational institutions; corporate communication departments; and by independent video and audio creative professionals and enthusiasts. Projects produced using Avid’s products include feature films, prime-time television shows, news programs, commercials, music, video and other recordings.
	The Company has generally funded operations in recent years through the use of existing cash balances and cash flows from operations, which have been supplemented from time to time with borrowings under credit facilities. At December 31, 2013, the Company’s principal sources of liquidity included cash and cash equivalents totaling $48.2 million and available borrowings under the Company’s credit facilities, which are discussed in Note R. Cash used in operating activities aggregated $9.1 million for the year ended December 31, 2013. This cash use reflected significant spending on restatement-related activities, restructuring related activities and executive management changes of $13.2 million, $13.2 million and $2.4 million, respectively. The spending associated with the restatement and restructuring activities is expected to materially abate by the end of 2014. The spending associated with the executive management changes was substantially completed in 2013.
	The Company’s cash requirements vary depending on factors such as the growth of the business, changes in working capital, capital expenditures, acquisitions of businesses or technologies and obligations under restructuring programs. Management expects to operate the business and execute its strategic initiatives principally with funds generated from operations and the Company’s external sources of credit under the credit facilities. Management anticipates that the Company will have sufficient internal and external sources of liquidity to fund operations and anticipated working capital and other expected cash needs for at least the next twelve months as well as for the foreseeable future.
	Principles of Consolidation
	The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. Intercompany balances and transactions have been eliminated.
	Basis of Presentation
	The Company’s 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 disclosures of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reported periods. Actual results could differ from the Company’s estimates.
	Subsequent Events
	On October 1, 2010, Avid Technology, Inc. and certain of its subsidiaries (the “Borrowers”) entered into a credit agreement with Wells Fargo Capital Finance LLC (“Wells Fargo”) that established two revolving credit facilities with combined maximum availability of up to $60 million for borrowings and letter of credit guarantees (the “Credit Agreement”). On August 29, 2014, the Company entered into an amendment (the “Amendment”) to its Credit Agreement with Wells Fargo. The Amendment (i) extended the maturity of the Credit Agreement from October 1, 2014 to October 1, 2015, (ii) changed the maximum amounts available under each of the revolving credit facilities, and (iii) added certain financial covenants, as described below.
	Under the Amendment, the maximum amount available for Avid Technology, Inc., (“Avid Technology”) was increased to $45 million (from $40 million) and the maximum amount available for its subsidiary Avid Technology International B.V. (“Avid Europe”) was decreased to $15 million (from $20 million). The maximum amount available under the combined credit facilities continues to be $60 million, subject to certain limitations on borrowing and other terms and conditions as provided in the Credit Agreement described in Note R.
	The Amendment further limits the Company’s ability to access borrowings under the credit facilities if (i) EBITDA (as defined in the Amendment) of $33.8 million is not achieved for the year ending December 31, 2014, or (ii) capital expenditures (as defined in the Amendment) exceed $16.0 million for the year ending December 31, 2014.
	The Company evaluated subsequent events through the date of issuance of these consolidated financial statements and, except for the subsequent events disclosed above and in Notes L, M and R, no other recognized or unrecognized subsequent events required recognition or disclosure in these financial statements.
	Revenue Recognition
	General
	The Company commences revenue recognition when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable and collection is reasonably assured. Generally, the products the Company sells do not require significant production, modification or customization. Installation of the Company’s products is generally routine, consists of implementation and configuration and does not have to be performed by Avid.
	The Company often receives multiple purchase orders or contracts from a single customer or a group of related customers that are evaluated to determine if they are, in effect, part of a single arrangement. In situations when the Company has concluded that two or more orders with the same customer are so closely related that they are, in effect, parts of a single arrangement, the Company accounts for those orders as a single arrangement for revenue recognition purposes. In other circumstances, when the Company has concluded that two or more orders with the same customer are independent buying decisions, such as an earlier purchase of a product and a subsequent purchase of a software upgrade or maintenance contract, the Company accounts for those orders as separate arrangements for revenue recognition purposes.
	For many of the Company’s products, there has been an ongoing practice of the Company making available at no charge to customers minor feature and compatibility enhancements as well as bug fixes on a when-and-if-available basis (collectively, “Software Updates”) for a period of time after initial sales to end users. The implicit obligation to make such Software Updates available to customers over a period of time represents implied post-contract customer support, which is deemed to be a deliverable in each arrangement and is accounted for as a separate element (referred to by the Company as “Implied Maintenance Release PCS”).
	The Company enters into certain contractual arrangements that have multiple elements, one or more of which may be delivered subsequent to the delivery of other elements. These multiple-deliverable arrangements may include products, support, training, professional services and Implied Maintenance Release PCS. In accordance with Accounting Standards Update (“ASU”) No. 2009-13, Multiple-Deliverable Revenue Arrangements, an amendment to ASC Topic 605 (“ASU No. 2009-13”) for these multiple-element arrangements, the Company allocates revenue to each deliverable of the arrangement based on the relative selling prices of the deliverables. In such circumstances, the Company first determines the selling price of each deliverable based on (i) vendor-specific objective evidence (“VSOE”) of fair value, if that exists; (ii) third-party evidence of selling price (“TPE”) when VSOE does not exist; or (iii) best estimate of the selling price (“BESP”) when neither VSOE nor TPE exists. Revenue is then allocated to the non-software deliverables as a group and to the software deliverables as a group using the relative selling prices of each of the deliverables in the arrangement based on the selling price hierarchy. The Company's process for determining BESP for deliverables for which VSOE or TPE does not exist involves significant management judgment. In determining BESP for each deliverable where it is required, the Company considers a number of data points, including:
	•	the pricing established by management when setting prices for deliverables that are intended to be sold on a standalone basis;
	•	contractually stated prices for deliverables that are intended to be sold on a standalone basis;
	•	the pricing of standalone sales that may not qualify as VSOE of fair value due to limited volumes or variation in prices; and
	•	other pricing factors, such as the geographical region in which products are sold and expected discounts based on the customer size and type.
	In determining a BESP for Implied Maintenance Release PCS, which the Company has never sold separately, management considers (i) the service period for the Implied Maintenance Release PCS, (ii) the differential in value of the Implied Maintenance Release PCS deliverable compared to a full support contract, (iii) the likely list price that would have resulted from the Company’s established pricing practices had the deliverable been offered separately, and (iv) the prices a customer would likely be willing to pay.
	The Company estimates service period of Implied Maintenance Release PCS based on the length of time the product version purchased by the customer is planned to be supported with Software Updates. If facts and circumstances indicate that the original deemed service period of Implied Maintenance Release PCS for a product has changed significantly after original revenue recognition has commenced, the Company will modify remaining estimated deemed service period accordingly and recognize the then-remaining deferred revenue balance over the revised deemed service period.
	The Company has established VSOE of fair value for all professional services and training and for some of its support offerings. The Company's policy for establishing VSOE of fair value consists of evaluating standalone sales, where available, to determine if a substantial portion of the transactions fall within a reasonable range. If a sufficient volume of standalone sales exist and the standalone pricing for a substantial portion of the transactions falls within a reasonable range, management concludes that VSOE of fair value exists.
	In accordance with ASU No. 2009-14, Certain Revenue Arrangements That Include Software Elements, an amendment to ASC Subtopic 985-605 (“ASU No. 2009-14”), the Company excludes from the scope of software revenue recognition requirements its sales of tangible products that contain both software and non-software components that function together to deliver the essential functionality of the tangible products. The Company adopted ASU No. 2009-13 and ASU No. 2009-14 prospectively on January 1, 2011 for new and materially modified arrangements originating after December 31, 2010.
	Prior to our adoption of ASU No. 2009-14, the Company primarily recognized revenues using the revenue recognition criteria of Accounting Standards Codification, or ASC, Subtopic 985-605, Software-Revenue Recognition. As a result of its adoption of ASU No. 2009-14 on January 1, 2011, a majority of the Company’s products are now considered non-software elements under GAAP, which excludes them from the scope of ASC Subtopic 985-605 and includes them within the scope of ASC Topic 605, Revenue Recognition. Because the Company had not been able to establish VSOE of fair value for Implied Maintenance Release PCS, as described further below, substantially all revenue arrangements prior to January 1, 2011 were recognized on a ratable basis over the service period of Implied Maintenance Release PCS. Subsequent to January 1, 2011 and the adoption of ASU No. 2009-14, the Company determines a relative selling price for all elements of the arrangement through the use of BESP, as VSOE and TPE are typically not available, resulting in revenue recognition upon delivery of arrangement consideration attributable to product revenue, provided all other criteria for revenue recognition are met, and revenue recognition of Implied Maintenance Release PCS and other service and support elements over time as services are rendered. As a result of the adoption of these standards, the Company recorded increased revenues and net income of approximately $300 million for the year ended December 31, 2011 (Restated) as compared with results that would have been recorded under the prior accounting standards.
	The timing of revenue recognition of customer arrangements follows a number of different accounting models determined by the characteristics of the arrangement, and that timing can vary significantly from the timing of related cash payments due from customers. One significant factor affecting the timing of revenue recognition is the determination of whether each deliverable in the arrangement is considered to be a software deliverable or a non-software deliverable, as defined under GAAP.
	Revenue Recognition of Non-Software Deliverables
	Revenue from products that are considered non-software deliverables is recognized upon delivery of the product to the customer. Products are considered delivered to the customer once they have been shipped and title and risk of loss have been transferred. For most of the Company’s product sales, these criteria are met at the time the product is shipped. Revenue from support that is considered a non-software deliverable is initially deferred and is recognized ratably over the contractual period of the arrangement, which is generally twelve months. Professional services and training services are typically sold to customers on a time and materials basis. Revenue from professional services and training services that are considered non-software deliverables is recognized for these deliverables as services are provided to the customer. Revenue for Implied Maintenance Release PCS that is considered a non-software deliverable is recognized ratably over the service period of Implied Maintenance Release PCS, which ranges from 1 to 8 years.
	Revenue Recognition of Software Deliverables
	The Company recognizes the following types of elements sold using software revenue recognition guidance: (i) software products and software upgrades, when the software sold in a customer arrangement is more than incidental to the arrangement as a whole and the product does not contain hardware that functions with the software to provide essential functionality, (ii) initial support contracts where the underlying product being supported is considered to be a software deliverable, (iii) support contract renewals, and (iv) professional services and training that relate to deliverables considered to be software deliverables. Because the Company does not have VSOE of the fair value of its software products, it is permitted to account for its typical customer arrangements that include multiple elements using the residual method. Under the residual method, the VSOE of fair value of the undelivered elements (which could include support, professional services or training, or any combination thereof) is deferred and the remaining portion of the total arrangement fee is recognized as revenue for the delivered elements. If evidence of the VSOE of fair value of one or more undelivered elements does not exist, revenues are deferred and recognized when delivery of those elements occurs or when VSOE of fair value can be established. VSOE is typically based on the price charged when the element is sold separately to customers. The Company is unable to use the residual method to recognize revenues for most arrangements that include products that are software deliverables under GAAP since VSOE of fair value does not exist for Implied Maintenance Release PCS elements, which are included in a majority of the Company’s arrangements.
	For software products that include Implied Maintenance Release PCS, an element for which VSOE of fair value does not exist, revenue for the entire arrangement fee, which could include combinations of product, professional services, training and support, is recognized ratably as a group over the longest service period of any deliverable in the arrangement, with recognition commencing on the date delivery has occurred for all deliverables in the arrangement (or begins to occur in the case of professional services, training and support). Standalone sales of support contracts are recognized ratably over the service period of the product being supported.
	From time to time, the Company offers certain customers free upgrades or specified future products or enhancements. When a software deliverable arrangement contains an Implied Maintenance Release PCS deliverable, revenue recognition of the entire arrangement will only commence when any free upgrades or specified future products or enhancements have been delivered, assuming all other products in the arrangement have been delivered and all services, if any, have commenced.
	Other Revenue Recognition Policies
	In a limited number of arrangements, the professional services and training to be delivered are considered essential to the functionality of the Company’s software products. If services sold in an arrangement are deemed to be essential to the functionality of the software products, the arrangement is accounted for using contract accounting. As the Company has concluded that it cannot reliably estimate its contract costs, the Company uses the completed contract method of contract accounting. The completed contract method of accounting defers all revenue and costs until the date that the products have been delivered and professional services, exclusive of post-contract customer support, have been completed. Deferred costs related to fully deferred contracts are recorded as a component of inventories in the consolidated balance sheet, and generally all other costs of sales are recognized when revenue recognition commences.
	The Company records as revenues all amounts billed to customers for shipping and handling costs and records its actual shipping costs as a component of cost of revenues. Reimbursements received from customers for out-of-pocket expenses are recorded as revenues, with related costs recorded as cost of revenues. The Company presents revenues net of any taxes collected from customers and remitted to government authorities.
	In the consolidated statements of operations, the Company classifies revenues as product revenues or services revenues. For multiple-element arrangements that include both product and service elements, including Implied Maintenance Release PCS, the Company evaluates available indicators of fair value and applies its judgment to reasonably classify the arrangement fee between product revenues and services revenues. The amount of multiple-element arrangement fees classified as product and service revenues based on management estimates of fair value when VSOE of fair value for all elements of an arrangement does not exist could differ from amounts classified as product and service revenues if VSOE of fair value for all elements existed.
	Allowance for Sales Returns and Exchanges
	The Company maintains allowances for estimated potential sales returns and exchanges from its customers. The Company records a provision for estimated returns and other allowances as a reduction of revenues in the same period that related revenues are recorded based on historical experience and specific customer analysis. Use of management estimates is required in connection with establishing and maintaining a sales allowance for expected returns and other credits. If actual returns differ from the estimates, additional allowances could be required.
	The following table sets forth the activity in the allowance for sales returns and exchanges for the years ended December 31, 2013, 2012 and 2011 (Restated) (in thousands):
		Year Ended December 31,
		2013				2012			2011 (Restated)
	Allowance for sales returns and exchanges – beginning of year	$	19,460			$	22,767		$	23,658
	Adjustments to the allowance	9,243				11,402			22,161
	Deductions against the allowance	(16,184		)		(14,709		)	(23,052		)
	Allowance for sales returns and exchanges – end of year	$	12,519			$	19,460		$	22,767
	Allowances for Doubtful Accounts
	The Company maintains allowances for estimated losses from bad debt resulting from the inability of its customers to make required payments for products or services. When evaluating the adequacy of the allowances, the Company analyzes accounts receivable balances, historical bad debt experience, customer concentrations, customer credit worthiness and current economic trends. To date, actual bad debts have not differed materially from management’s estimates.
	The following table sets forth the activity in the allowance for doubtful accounts for the years ended December 31, 2013, 2012 and 2011 (Restated) (in thousands):
		Year Ended December 31,
		2013				2012			2011 (Restated)
	Allowance for doubtful accounts – beginning of year	$	1,517			$	2,401		$	2,928
	Additions to the allowance	157				125			1,473
	Deductions against the allowance	(230		)		(1,009		)	(2,000		)
	Allowance for doubtful accounts – end of year	$	1,444			$	1,517		$	2,401
	Translation of Foreign Currencies
	The functional currency of each of the Company’s foreign subsidiaries is the local currency, except for the Irish manufacturing branch whose functional currency is the U.S. dollar due to the extensive interrelationship of the operations of the Irish branch and the U.S. parent and the high volume of intercompany transactions between that branch and the parent. The assets and liabilities of the subsidiaries whose functional currencies are other than the U.S. dollar are translated into U.S. dollars at the current exchange rate in effect at the balance sheet date. Income and expense items for these entities are translated using rates that approximate those in effect during the period. Cumulative translation adjustments are included in accumulated other comprehensive income (loss), which is reflected as a separate component of stockholders’ deficit. The Company does not record tax provisions or benefits for the net changes in the foreign currency translation adjustment as the Company intends to permanently reinvest undistributed earnings in its foreign subsidiaries.
	The U.S. parent company and its Irish manufacturing branch, both of whose functional currency is the U.S. dollar, carry certain monetary assets and liabilities denominated in currencies other than the U.S. dollar. These assets and liabilities typically include cash, accounts receivable and intercompany operating balances denominated in foreign currencies. These assets and liabilities are remeasured into the U.S. dollar at the current exchange rate in effect at the balance sheet date. Foreign currency transaction and remeasurement gains and losses are included within marketing and selling expenses in the results of operations. See Note D for the net foreign exchange gains and losses recorded in the Company’s statements of operations during the years ended December 31, 2013, 2012 and 2011 (Restated) that resulted from the gains and losses on Company’s foreign currency contracts and the revaluation of the related hedged items.
	The U.S. parent company and various other wholly owned subsidiaries have long-term intercompany loan balances denominated in foreign currencies that are remeasured into the U.S. dollar at the current exchange rate in effect at the balance sheet date. Such loan balances are not expected to be settled in the foreseeable future. Any gains and losses relating to these loans are included in the accumulated other comprehensive income (loss), which is reflected as a separate component of stockholders’ deficit.
	Cash, Cash Equivalents and Marketable Securities
Cash equivalents consist primarily of commercial paper, money market investments and certificates of deposit. The Company considers all debt instruments purchased with an original maturity of three months or less to be cash equivalents. Marketable securities, have historically consisted of certificates of deposit, commercial paper, asset-backed securities, discount notes, and corporate, municipal, agency and foreign bonds. The Company generally invests in securities that mature within one year from the date of purchase. The Company classifies its cash equivalents and marketable securities as “available for sale” and reports them at fair value, with unrealized gains and losses excluded from earnings and reported as an adjustment to other comprehensive income (loss), which is reflected as a separate component of stockholders’ deficit. Amortization or accretion of premium or discount is included in interest income (expense) in the results of operations. Other than those investments held in the Company’s deferred compensation plan, the Company held no available for sale securities classified as either cash equivalents or marketable securities at December 31, 2013 or 2012.
Cash equivalents and marketable securities, including money market investments and mutual funds accounted for as trading securities, held in the Company’s deferred compensation plan are reported at fair value using quoted prices with the gains and losses included as other income (expense) in the Company’s statement of operations. Realized gains and losses from the Company’s deferred compensation plans were not material for the years ended December 31, 2013, 2012 and 2011 (Restated).
Concentration of Credit Risk
Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents, foreign currency contracts and accounts receivable. The Company may place its excess cash in marketable investment grade securities and uses foreign currency contracts to manage certain of its short-term exposures to fluctuations in foreign currency exchange rates. The Company places its cash and cash equivalents and foreign currency contracts with financial institutions that management believes to be of high credit quality, and, generally, there are no significant concentrations in any one issuer of debt securities. Concentrations of credit risk with respect to trade receivables are limited due to the large number of customers that make up the Company’s customer base and their dispersion across different regions. No individual customer accounted for 10% or more of the Company’s net revenues or net accounts receivable in the periods presented.
Foreign Currency Risk
The Company has significant international operations and, therefore, the Company’s revenues, earnings, cash flows and financial position are exposed to foreign currency risk from foreign-currency-denominated receivables, payables, sales and expense transactions, and net investments in foreign operations. The Company derives more than half of its revenues from customers outside the United States. This business is, for the most part, transacted through international subsidiaries and generally in the currency of the end-user customers. Therefore, the Company is exposed to the risks that changes in foreign currency could adversely affect its revenues, net income, cash flow and financial position. The Company uses derivatives in the form of foreign currency contracts to manage its short-term exposures to fluctuations in the foreign currency exchange rates that exist as part of its ongoing international business operations. The Company does not enter into any derivative instruments for trading or speculative purposes.
The Company records all foreign currency contract derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as hedges of the exposure to changes in the fair value of an asset, liability or firm commitment attributable to a particular risk are considered fair value hedges. Derivatives designated and qualifying as hedges of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. Under hedge accounting, the determination of hedge effectiveness is dependent upon whether the gain or loss on the hedging derivative is highly effective in offsetting the gain or loss in the value of the item being hedged.
Inventories
Inventories are stated at the lower of cost (determined on a first-in, first-out basis) or market value. Management regularly reviews inventory quantities on hand and writes down inventory to its realizable value to reflect estimated obsolescence or lack of marketability based on assumptions about future inventory demand and market conditions. Inventory in the digital-media market, including the Company’s inventory, is subject to rapid technological change or obsolescence; therefore, utilization of existing inventory may differ from the Company’s estimates.
Property and Equipment
Property and equipment is recorded at cost and depreciated using the straight-line method over the estimated useful life of the asset. The Company typically depreciates its property and equipment using the following minimum and maximum useful lives:
		Depreciable Life (years)
		Minimum		Maximum
Computer and video equipment and software		2		5
Manufacturing tooling and testbeds		3		5
Office equipment		3		5
Furniture, fixtures and other		3		8
Leasehold improvements are amortized over the shorter of the useful life of the improvement or the remaining term of the lease. Expenditures for maintenance and repairs are expensed as incurred. Upon retirement or other disposition of assets, the cost and related accumulated depreciation are eliminated from the accounts and the resulting gain or loss is reflected in other income (expense) in the results of operations.
Intangible Assets
Intangible assets consist of acquired and internally developed assets. Acquired intangible assets include customer relationships, developed technology, trade names and non-compete agreements from acquisitions. Internally developed assets consist primarily of various technologies that form the basis of products sold to customers. Costs are capitalized from when technological feasibility is established up until when the product is available for general release. Intangible assets are determined to have either finite or indefinite lives. For finite-lived intangible assets amortization is straight-line over the estimated useful lives of such assets, which are generally two years to twelve years. Straight-line amortization is used because the Company cannot reliably determine a discernible pattern over which the economic benefits would be realized. The Company does not have any indefinite-lived intangible assets. Intangible assets are tested for impairment when events and circumstances indicate there is an impairment. The impairment test involves comparing the sum of undiscounted cash flows to the carrying value as of the measurement date. Impairment occurs when the carrying value of the assets exceeds the sum of undiscounted cash flows. Impairment is then measured as the difference between the carrying value and fair value determined using a discounted cash flow method. In estimating the fair value using a discounted cash flow method, the Company uses assumptions that include forecast revenues, gross margins, operating profit margins, growth rates and long term discount rates, all of which require significant judgment by management. Changes to these assumptions could affect the estimated fair value of the intangible asset and could result in an impairment charge in future.
Discontinued Operations
The Company classifies the assets and liabilities of a business as held-for-sale when management approves and commits to a formal plan of sale and it is probable that the sale will be completed. The carrying value of the net assets of the business held-for-sale are then recorded at the lower of their carrying value or fair market value, less costs to sell. As discussed in Note I, the Company completed the sales of the consumer audio and consumer video product lines in the third quarter of 2012. The operations of divested businesses have been reflected as discontinued operations for all periods presented in these consolidated financial statements.
Long-Lived Assets
The Company periodically evaluates its long-lived assets for events and circumstances that indicate a potential impairment. A long-lived asset is assessed for impairment when the undiscounted expected future cash flows derived from that asset are less than its carrying value. The cash flows used for this analysis take into consideration a number of factors including past operating results, budgets and economic projections, market trends and product development cycles. The amount of any impairment would be equal to the difference between the estimated fair value of the asset, based on a discounted cash flow analysis, and its carrying value.
Advertising Expenses
All advertising costs are expensed as incurred and are classified as marketing and selling expenses. Advertising expenses during 2013, 2012 and 2011 (Restated) were $1.8 million, $3.1 million and $3.8 million, respectively.
Research and Development Costs
Research and development costs are expensed as incurred, except for costs that qualify for capitalization. Development costs for software to be sold that are incurred subsequent to the establishment of technological feasibility, but prior to the general release of the product, are capitalized. Upon general release, these costs are amortized using the straight-line method over the expected life of the related products, generally 12 to 36 months. The straight-line method generally results in approximately the same amount of expense as that calculated using the ratio that current period gross product revenues bear to total anticipated gross product revenues. The Company periodically evaluates the assets, considering a number of business and economic factors, to determine if an impairment exits.
Income Taxes
The Company accounts for income taxes using an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Company’s financial statements or tax returns. The Company records deferred tax assets and liabilities based on the net tax effects of tax credits, operating loss carryforwards and temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes compared to the amounts used for income tax purposes. Deferred tax assets are regularly reviewed for recoverability with consideration for such factors as historical losses, projected future taxable income and the expected timing of the reversals of existing temporary differences. The Company is required to record a valuation allowance when it is more likely than not that some portion or all of the deferred tax assets will not be realized. Based on the magnitude of the Company’s deferred tax assets at December 31, 2013 and the historical U.S. losses, the Company has determined that the uncertainty regarding the realization of these assets is sufficient to warrant the need for a full valuation allowance against its U.S. net deferred tax assets. The Company has also determined that a valuation allowance is warranted on a portion of its foreign deferred tax assets.
The Company accounts for uncertainty in income taxes recognized in its financial statements by applying a two-step process to determine the amount of tax benefit to be recognized. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon examination by the taxing authorities, based on the technical merits of the position. If the tax position is deemed more-likely-than-not to be sustained, the tax position is then assessed to determine the amount of benefit to recognize in the financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. The provision for income taxes includes the effects of any resulting tax reserves (“unrecognized tax benefits”) that are considered appropriate as well as the related net interest and penalties.
Accounting for Stock-Based Compensation
The Company’s stock-based employee compensation plans allow the Company to grant stock awards, options, or other equity-based instruments, or a combination thereof, as part of its overall compensation strategy. For stock-based awards granted, the Company records stock-based compensation cost based on the grant date fair value over the requisite service periods for the individual awards, which generally equal the vesting periods. The vesting of stock-based award grants may be based on time, performance conditions, market conditions, or a combination of performance or market conditions.
Product Warranties
The Company provides warranties on externally sourced and internally developed hardware. The warranty period for all of the Company’s products is generally 90 days to one year, but can extend up to five years depending on the manufacturer’s warranty or local law. For internally developed hardware and in cases where the warranty granted to customers for externally sourced hardware is greater than that provided by the manufacturer, the Company records an accrual for the related liability based on historical trends and actual material and labor costs. At the end of each quarter, the Company reevaluates its estimates to assess the adequacy of the recorded warranty liabilities and adjusts the accrued amounts accordingly.
Computation of Net Income Per Share
Net income per share is presented for both basic earnings per share (“Basic EPS”) and diluted earnings per share (“Diluted EPS”). Basic EPS is based on the weighted-average number of common shares outstanding during the period, excluding non-vested restricted stock held by employees. Diluted EPS is based on the weighted-average number of common and potential common shares outstanding during the period. Potential common shares result from the assumed exercise of outstanding stock options and non-vested restricted stock and restricted stock units, the proceeds and remaining unrecorded compensation expense of which are then assumed to have been used to repurchase outstanding common stock using the treasury stock method. For periods when the Company reports a loss, all potential common stock is considered anti-dilutive. For periods when the Company reports net income, potential common shares with combined purchase prices and unamortized compensation costs in excess of the Company’s average common stock fair value for the related period or that are contingently issuable are considered anti-dilutive. The contingently issuable potential common shares result from certain stock options and restricted stock units granted to the Company’s executive officers that vest based on performance conditions, market conditions, or a combination of performance or market conditions (see Notes C and M).
Accounting for Restructuring Plans
The Company records facility-related restructuring charges in accordance with ASC Topic 420, Liabilities: Exit or Disposal Cost Obligations. Based on the Company’s policies for the calculation and payment of severance benefits, the Company accounts for employee-related restructuring charges as an ongoing benefit arrangement in accordance with ASC Topic 712, Compensation - Nonretirement Postemployment Benefits. Restructuring charges and accruals require significant estimates and assumptions, including sub-lease income assumptions. These estimates and assumptions are monitored on at least a quarterly basis for changes in circumstances and any corresponding adjustments to the accrual are recorded in the Company’s statement of operations in the period when such changes are known.
Recent Accounting Pronouncements To Be Adopted
On May 28, 2014, the Financial Accounting Standards Board (the “FASB”) and the International Accounting Standards Board (the “IASB”) issued substantially converged final standards on revenue recognition. The FASB's Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606), was issued in three parts: (a) Section A, “Summary and Amendments That Create Revenue from Contracts with Customers (Topic 606) and Other Assets and Deferred Costs-Contracts with Customers (Subtopic 340-40),” (b) Section B, “Conforming Amendments to Other Topics and Subtopics in the Codification and Status Tables” and (c) Section C, “Background Information and Basis for Conclusions.” The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance.
The new revenue recognition guidance becomes effective for the Company on January 1, 2017, and early adoption is not permitted. Entities have the option of using either a full retrospective or a modified approach to adopt the guidance in the ASU.  The Company has not yet selected a transition method and is currently evaluating the effect that the updated standard will have on its consolidated financial statements and related disclosures.

RESTATEMENT OF CONSOLIDATED FINANCIAL STATEMENTS (Notes)	12 Months Ended
	Dec. 31, 2013
Accounting Policies [Abstract]	'
RESTATEMENT OF CONSOLIDATED FINANCIAL STATEMENTS	'
	RESTATEMENT OF CONSOLIDATED FINANCIAL STATEMENTS
	Background
	In early 2013, during the course of the Company’s review of its financial results for the fourth quarter and full year of 2012, management identified a historical practice of the Company making available, at no charge to its customers, minor feature and/or compatibility enhancements, as well as bug fixes on a when-and-if-available basis (collectively, “Software Updates”) that management has concluded meets the definition of post-contract customer support (“PCS”) under U.S. GAAP. The business practice of providing Software Updates at no charge for many of the Company’s products creates an implicit obligation and an additional undelivered element for each impacted arrangement (referred to as “Implied Maintenance Release PCS”). The Company’s identification of this additional undelivered element in substantially all of its customer arrangements has a significant impact on the historical revenue recognition policies because this element had not been previously accounted for in any period.
	As a result of the foregoing and as explained in more detail below, the Company has restated its consolidated financial statements for the year ended December 31, 2011. The restatement also affects periods prior to the year ended December 31, 2011, and the cumulative effects of the restatement have been reflected as prior period adjustments to the 2011 opening balance of accumulated deficit.
	Restatement Adjustments
	Revenue Recognition
	The failure to identify and account for the existence of Implied Maintenance Release PCS resulted in errors in the timing of revenue recognition reported in the Company’s previously issued consolidated financial statements. Historically, the Company generally recognized revenue upon product shipment or over the period services and post-contract customer support were provided (assuming other revenue recognition conditions were met). As described more fully in the Company’s policy for “Revenue Recognition” in Note A, the existence of Implied Maintenance Release PCS in a customer arrangement requires recognition of some or all arrangement consideration, depending on GAAP applicable to the deliverables, over the period of time that the Implied Maintenance Release PCS is delivered, which is after product delivery or services are rendered and is generally several years. The errors in the timing of revenue recognition have been corrected in the restated consolidated financial statements. The significant change in the pattern of revenue recognition also had indirect impacts on revenue related accounts, such as sales return allowances and, as discussed further below, non-revenue accounts such as goodwill, stock-based compensation and income taxes, which have also been restated in the restated consolidated financial statements.
	Goodwill
	As a result of the change in the timing of revenue recognition described above and the resulting increase in deferred revenues, the carrying values of the reporting units used in the Company’s original goodwill impairment tests were incorrect for each historical period impacted by the restatement of revenue, including those periods in which impairment charges totaling $172.4 million had been recorded. The decrease in carrying value of the reporting units arising from the deferred revenue resulted in negative carrying value and changes to the original step one conclusions that further considerations of goodwill impairment were required under step two, and, as such, no impairment should have been recognized in the periods prior to January 1, 2011. As a result, the carrying value of goodwill was restated to $419.4 million at December 31, 2010. On January 1, 2011, the Company adopted ASU No. 2010-28, When to Perform Step 2 of the Goodwill Impairment Test for Reporting Units with Zero or Negative Carrying Amounts (“ASU No. 2010-28”).  ASU No. 2010-28 requires companies with negative carrying value of a reporting unit to perform step two of the impairment test when it is more likely than not that a goodwill impairment exists. Upon adoption of ASU No. 2010-28, the Company recorded a full impairment of goodwill through a cumulative-effect adjustment to accumulated deficit. The decline in the fair value of goodwill that caused the impairment was the result of declines in actual and expected cash flows that occurred over a several-year period prior to December 31, 2010.
	The following table presents the adjustments to goodwill for the year ended December 31, 2011 (Restated) (in thousands):
	Goodwill balance at December 31, 2010, as previously reported	$	246,997
	Effect of restatement	172,371
	Goodwill balance at December 31, 2010, as restated	419,368
	Cumulative-effect adjustment due to the adoption of ASU No. 2010-28	(419,368		)
	Goodwill balance at December 31, 2011, as restated	$	—
	Stock-Based Compensation
	As a result of the change in the timing of revenue recognition described above, the timing and amount of stock-based compensation expense attributable to performance-based awards, where expected vesting was based on profitability, also changed. Due to the restated historical financial statements, many of the performance-based awards have vested earlier than originally estimated.
	Restructuring
	The Company also identified errors in a restructuring charge recorded in the year ended December 31, 2009. The Company originally assumed that a vacated facility could be sublet, reducing the restructuring expense by $2.2 million at that time. Subsequently, management determined that contractual provisions severely limited the Company from executing a sublease, which resulted in no possible sublease income at the time of lease abandonment. The cumulative effect of this error and other restructuring-related adjustments totaling $1.5 million at December 31, 2010 was reflected as an adjustment to the 2011 opening balance of accumulated deficit.
	Income Taxes
	The Company identified and corrected certain errors related to the accounting for an intercompany loan made between two of its international subsidiaries that occurred during the year ended December 31, 2007. The Company determined that it should have accrued withholding taxes of $3.8 million, and as a result the Company had understated the provision for income taxes in 2007 and income taxes payable reported on its balance sheets for each period subsequent to the transaction. Additionally, as the tax was not withheld and paid to the taxing authority, the Company is subject to interest and penalties on the unpaid balance. The cumulative effect of this error and other adjustments totaling $6.2 million at December 31, 2010 was reflected as an adjustment to the 2011 opening balance of accumulated deficit. The Company also adjusted income taxes as necessary to reflect the impact of the changes in the timing of revenue recognition described above. The Company also identified several errors in the compilation of its deferred tax assets and liabilities. Due to the valuation allowance the Company had recorded against gross deferred tax assets, the adjustments had no net effect on its financial results; however, the corrected balances are reflected in Note O.
	Other Adjustments
	In addition to correcting the restatement adjustments described above, the Company also recorded other adjustments for other errors identified during the restatement process, including adjustments of $5.1 million to inventory and adjustments to accrued liabilities, as well as reclassifications of operating expenses to cost of revenues totaling $9.5 million.
	Cumulative Effect of Prior Period Adjustments
	The following tables present the cumulative effect of the prior period adjustments to stockholders’ deficit at December 31, 2010 and 2011 (in thousands):
		Common Stock				Additional Paid-in Capital				Accumulated Deficit				Treasury Stock			Accumulated Other Comprehensive Income		Total Stockholders’ Equity (Deficit)

	Discontinued Operations
	On July 2, 2012, the Company exited its consumer business through the sale of the assets of that business in two separate transactions. As described further in Note I, the disposition of the consumer business qualified for presentation as a discontinued operation; therefore, these financial statements have been retrospectively adjusted for all periods presented to report the consumer business as a discontinued operation. The Adjustments to Consolidated Statement of Operations and Adjustments to Consolidated Statement of Cash Flows tables below also include a column for discontinued operations to allow reconciliation back to the originally issued financial statements.

	The following table sets forth (in thousands) potential common shares, on a weighted-average basis, that were considered anti-dilutive securities and excluded from the diluted earnings per share calculations for the relevant periods either because the sum of the exercise price per share and the unrecognized compensation cost per share was greater than the average market price of the Company’s common stock for the relevant period, or because they were considered contingently issuable. The contingently issuable potential common shares result from certain stock options and restricted stock units granted to the Company’s executive officers that vest based on performance conditions, market conditions, or a combination of performance or market conditions.

FOREIGN CURRENCY FORWARD CONTRACTS	'
	FOREIGN CURRENCY CONTRACTS
	As a hedge against the foreign exchange exposure of certain forecasted receivables, payables and cash balances of its foreign subsidiaries, the Company enters into short-term foreign currency forward contracts. The changes in fair value of the foreign currency forward contracts intended to offset foreign currency exchange risk on cash flows associated with net monetary assets are recorded as gains or losses in the Company’s statement of operations in the period of change, because these contracts have not been accounted for as hedges. There are two objectives of the Company’s foreign currency forward-contract program: (1) to offset any foreign currency exchange risk associated with cash receipts expected to be received from the Company’s customers and cash payments expected to be made to the Company’s vendors over the following 30 days and (2) to offset the impact of foreign currency exchange on the Company’s net monetary assets denominated in currencies other than the functional currency of the legal entity. These forward contracts typically mature within 30 days of execution. At December 31, 2013 and 2012, the Company had foreign currency forward contracts outstanding with aggregate notional values of $21.0 million and $23.6 million, respectively, as hedges against such forecasted foreign-currency-denominated receivables, payables and cash balances.
	The Company may also enter into short-term foreign currency spot and forward contracts as a hedge against the foreign currency exchange risk associated with certain of its net monetary assets denominated in foreign currencies. At December 31, 2013 and 2012, the Company had such foreign currency contracts with aggregate notional values of $5.4 million and $5.3 million, respectively. Because these contracts have not been accounted for as hedges, the changes in fair value of these foreign currency contracts are recorded as gains or losses in the Company’s statement of operations.
	The following table sets forth the balance sheet classification and fair values of the Company’s foreign currency contracts at December 31, 2013 and 2012 (in thousands):
	Derivatives Not Designated as Hedging Instruments Under	Balance Sheet Classification	Fair Value at December 31, 2013	Fair Value at December 31, 2012

	FAIR VALUE MEASUREMENTS
	Assets and Liabilities Measured at Fair Value on a Recurring Basis
	On a recurring basis, the Company measures certain financial assets and liabilities at fair value, including foreign-currency contracts, cash equivalents, marketable securities and insurance contracts held in deferred compensation plans. At December 31, 2013 and 2012, all of the Company’s financial assets and liabilities were classified as either Level 1 or Level 2 in the fair value hierarchy. Assets valued using quoted market prices in active markets and classified as Level 1 are certain deferred compensation investments, primarily money market and mutual funds. Assets and liabilities valued based on other observable inputs and classified as Level 2 are foreign currency contracts and certain deferred compensation investments.
	The following tables summarize the Company’s fair value hierarchy for its financial assets and liabilities measured at fair value on a recurring basis at December 31, 2013 and 2012 (in thousands):
				Fair Value Measurements at Reporting Date Using
		December 31,		Quoted Prices in		Significant		Significant
		2013		Active Markets		Other		Unobservable
				for Identical		Observable		Inputs
				Assets (Level 1)		Inputs (Level 2)		(Level 3)

	Deferred compensation assets	$	1,920	$	1,271	$	649	$	—
	Foreign currency contracts	59		—		59		—
	Financial Liabilities:
	Foreign currency contracts	$	228	$	—	$	228	$	—

		31-Dec-12		Quoted Prices in		Significant		Significant
				Active Markets		Other		Unobservable

				Assets (Level 1)		Inputs (Level 2)		(Level 3)
	Financial Assets:
	Deferred compensation assets	$	1,680	$	1,097	$	583	$	—
	Foreign currency contracts	157		—		157		—
	Financial Liabilities:
	Foreign currency contracts	$	337	$	—	$	337	$	—
	The fair values of Level 1 deferred compensation assets are determined using a market approach based on quoted market prices of the underlying securities. The fair values of the Level 2 deferred compensation assets are determined using an income approach based on observable inputs including the prices for recently traded financial instruments with similar underlying terms as well as directly or indirectly observable inputs, such as interest rates and yield curves that are observable at commonly quoted intervals.
	The fair values of foreign currency contracts are classified as Level 2 in the fair value hierarchy and are measured at fair value on a recurring basis using an income approach based on observable inputs. The primary inputs used to fair value foreign currency contracts are published foreign currency exchange rates as of the date of valuation. See Note D for information on the Company’s foreign currency contracts.
	Financial Instruments Not Recorded at Fair Value
	The carrying amounts of the Company’s other financial assets and liabilities including cash, accounts receivable, accounts payable and accrued liabilities approximate their respective fair values because of the relatively short period of time between their origination and their expected realization.

	On July 2, 2012, the Company sold a group of consumer audio and video products and certain related intellectual property (the “Consumer Business”) with a negative carrying value of $25.0 million for total consideration of $14.8 million, of which $13.3 million was received during 2012, recording a gain of $38.0 million net of $1.9 million of costs incurred to sell the assets. The audio assets were sold to Numark Industries, L.P. (“Numark”) for $11.8 million. Proceeds of $10.9 million were received from Numark in 2012, with the remaining proceeds held in escrow until a final release date that occurred in March 2014. The video assets were sold to Corel Corporation (“Corel”) for $3.0 million. Proceeds of $2.4 million were received from Corel in 2012, with the remaining proceeds held in escrow until a final release date that occurred in January 2014. There was no income tax provision related to the discontinued operations in any period presented.
	The divestiture of these consumer product lines was intended to:
	•	allow the Company to focus on the Broadcast and Media market and the Video and Audio Post and Professional market;
	•	reduce complexity from the Company's operations to improve operational efficiencies; and
	•	allow the Company to change its cost structure, by moving away from lower growth, lower margin sectors to drive improved financial performance.

	COMMITMENTS AND CONTINGENCIES
	Operating Lease Commitments
	The Company leases its office space and certain equipment under non-cancelable operating leases. The future minimum lease commitments under these non-cancelable leases at December 31, 2013 were as follows (in thousands):
	Year Ending December 31,
	2014	$	20,183
	2015	13,462
	2016	12,503
	2017	11,301
	2018	9,126
	Thereafter	18,500
	Total	$	85,075
	Included in the operating lease commitments above are obligations under leases for which the Company has vacated the underlying facilities as part of various restructuring plans. These leases expire at various dates through 2021 and represent an aggregate obligation of $10.3 million through 2021. The Company has restructuring accruals of $6.1 million at December 31, 2013, which represents the difference between this aggregate future obligation and expected future sublease income under actual or estimated potential sublease agreements, on a net present value basis, as well as other facilities-related obligations. The Company received no sublease income during the years ended December 31, 2013, 2012 or 2011.
	The Company’s leases for corporate office space in Burlington, Massachusetts, which expire in May 2020, contain renewal options to extend the respective terms of each lease for up to two additional five-year periods. The Company has some leases for office space that have early termination options, which, if exercised by the Company, would result in penalties of $0.7 million in the aggregate. The future minimum lease commitments above include the Company’s obligations through the original lease terms and do not include these penalties.
	The accompanying consolidated results of operations reflect rent expense on a straight-line basis over the term of the leases. Total expense under operating leases was $16.3 million, $18.1 million and $20.2 million for the years ended December 31, 2013, 2012 and 2011 (Restated), respectively.
	Other Commitments
	The Company has letters of credit at a bank that are used as security deposits in connection with the Company’s Burlington, Massachusetts office space. In the event of default on the underlying leases, the landlords would, at December 31, 2013, be eligible to draw against the letters of credit to a maximum of $2.6 million in the aggregate. The letters of credit are subject to aggregate reductions provided the Company is not in default under the underlying leases and meets certain financial performance conditions. In no case will the letters of credit amounts be reduced to below $1.2 million in the aggregate throughout the lease periods, all of which extend to May 2020.
	The Company also has a standby letter of credit at a bank that is used as a security deposit in connection with the Company’s Daly City, California office space lease. In the event of default on this lease, the landlord would, at December 31, 2013, be eligible to draw against this letter of credit to a maximum of $0.8 million. The letter of credit will remain in effect at this amount throughout the remaining lease period, which extends to September 2014. The Company is not renewing this lease at the end of the term and expects the letter of credit to be released at that time.
	The Company also has additional letters of credit totaling $2.4 million that support its ongoing operations. These letters of credit have various terms and expire during 2014 and 2015. Some of the letters of credit may automatically renew based on the terms of the underlying agreements.
	Purchase Commitments and Sole-Source Suppliers
	At December 31, 2013, the Company had entered into purchase commitments for certain inventory and other goods and services used in its normal operations. The purchase commitments covered by these agreements are generally for a period of less than one year and in the aggregate total approximately $27.6 million.
	The Company depends on sole-source suppliers for certain key hardware components of its products. Although the Company has procedures in place to mitigate the risks associated with its sole-sourced suppliers, the Company cannot be certain that it will be able to obtain sole-sourced components or finished goods from alternative suppliers or that it will be able to do so on commercially reasonable terms without a material impact on its results of operations or financial position. The Company procures product components and builds inventory based on forecasts of product life cycle and customer demand. If the Company is unable to provide accurate forecasts or manage inventory levels in response to shifts in customer demand, the Company may have insufficient, excess or obsolete product inventory.
	Contingencies
	In March 2013 and May 2013, two purported securities class action lawsuits were filed against the Company and certain of its former executive officers seeking unspecified damages in the U.S. District Court for the District of Massachusetts. In July 2013, the two cases were consolidated and the original plaintiffs agreed to act as co-plaintiffs in the consolidated case. In September 2013, the co-plaintiffs filed a consolidated amended complaint on behalf of those who purchased the Company’s common stock between October 23, 2008 and March 20, 2013. The consolidated amended complaint, which named the Company, certain of its current and former executive officers and its former independent accounting firm as defendants, purported to state a claim for violation of federal securities laws as a result of alleged violations of the federal securities laws pursuant to Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder. In October 2013, the Company filed a motion to dismiss the consolidated amended complaint, resulting in the dismissal of some of the claims, and the dismissal of Mr. Hernandez and one of the two plaintiffs from the case. The matter is scheduled for trial in March 2015. At this time, the Company believes that a loss related to the consolidated complaint is neither probable nor remote, and based on the information currently available regarding the claims in the consolidated complaint, the Company is unable to determine an estimate, or range of estimates, of potential losses.
	In June 2013, a purported stockholder of the Company filed a derivative complaint against the Company as nominal defendant and certain of the Company’s current and former directors and officers. The complaints alleged various violations of state law, including breaches of fiduciary duties, waste of corporate assets and unjust enrichment. The derivative complaint sought, inter alia, unspecified monetary judgment, equitable and/or injunctive relief, restitution, disgorgement and a variety of purported corporate governance reforms. On October 30, 2013, the complaint was dismissed without prejudice. On November 26, 2013, the Company’s Board of Directors received a letter from the plaintiff in the dismissed derivative suit, demanding that the Company’s Board of Directors investigate, address and commence proceedings against certain of the Company’s directors, officers, employees and agents based on conduct identified in the dismissed complaint. In December 2013, the Company’s Board created a committee to conduct an investigation into the allegations in the demand letter. At this time, the Company believes that a loss related to the demand letter is neither probable nor remote, and based on the information currently available regarding the claims in the demand letter, the Company is unable to determine an estimate, or range of estimates, of potential losses.
	In April and May 2013, the Company received a document preservation request and inquiry from the SEC’s Division of Enforcement and a federal grand jury subpoena from the Department of Justice requesting certain documents, including in particular documents related to the Company’s disclosures regarding its accounting review and financial transactions. The Company has produced documents responsive to such requests and has provided regular updates to the authorities on its accounting evaluation. The Company intends to continue to cooperate fully with the authorities.  At this time, the Company believes that a loss related to the inquiries is neither probable nor remote, and based on the information currently available regarding these inquiries, the Company is unable to determine an estimate, or range of estimates, of potential losses.
	At December 31, 2013, the Company was subject to various litigations claiming patent infringement by the Company.  Some of these legal proceedings may include speculative claims for substantial or indeterminate amounts of damages. If any infringement is determined to exist, the Company may seek licenses or settlements. In addition, as a normal incidence of the nature of the Company’s business, various claims, charges and litigation have been asserted or commenced from time to time against the Company arising from or related to contractual, employee relations, intellectual property rights, product or service performance, or other matters.
	The Company considers all claims on a quarterly basis and based on known facts assesses whether potential losses are considered reasonably possible, probable and estimable. Based upon this assessment, the Company then evaluates disclosure requirements and whether to accrue for such claims in its consolidated financial statements.
	The Company records a provision for a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These provisions are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular case.
	At December 31, 2013 and as of the date of filing of these consolidated financial statements, the Company believes that, other than as set forth in this note, no provision for liability nor disclosure is required related to any claims because: (a) there is no reasonable possibility that a loss exceeding amounts already recognized (if any) may be incurred with respect to such claim; (b) a reasonably possible loss or range of loss cannot be estimated; or (c) such estimate is immaterial.
	Additionally, the Company provides indemnification to certain customers for losses incurred in connection with intellectual property infringement claims brought by third parties with respect to the Company’s products.  These indemnification provisions generally offer perpetual coverage for infringement claims based upon the products covered by the agreement and the maximum potential amount of future payments the Company could be required to make under these indemnification provisions is theoretically unlimited.  To date, the Company has not incurred material costs related to these indemnification provisions; accordingly, the Company believes the estimated fair value of these indemnification provisions is immaterial. Further, certain of the Company’s arrangements with customers include clauses whereby the Company may be subject to penalties for failure to meet certain performance obligations; however, the Company has not recorded any related material penalties to date.
	During 2010, the Company’s Canadian subsidiary, Avid Technology Canada Corporation, was assessed and paid to the Ministry of Revenue Quebec (“MRQ”) approximately CAN $1.7 million for social tax assessments on Canadian employee stock-based compensation related to the Company’s stock plans. The payment amounts were recorded in “other current assets” in the Company’s consolidated balance sheets at December 31, 2012. During 2013, the Quebec Court of Appeals rendered a judgment against the MRQ in a similar case, and a subsequent appeal by the MRQ was dismissed by the Supreme Court of Canada. As a result, the MRQ filed a Declaration of Settlement related to the Avid case in November 2013, and this matter is considered closed. In December 2013, the MRQ refunded to the Company CAN $1.9 million for tax assessments for 2001 through 2006 and related interest. The tax assessments for 2007 through 2011 are not material and are expected to be refunded with interest during 2014.
	The Company provides warranties on externally sourced and internally developed hardware. For internally developed hardware and in cases where the warranty granted to customers for externally sourced hardware is greater than that provided by the manufacturer, the Company records an accrual for the related liability based on historical trends and actual material and labor costs. The following table sets forth the activity in the product warranty accrual account for the years ended December 31, 2013, 2012 and 2011 (in thousands):
	Accrual balance at December 31, 2010 (Restated)	$	4,849

	CAPITAL STOCK
	Preferred Stock
	The Company has authorized up to one million shares of preferred stock, $0.01 par value per share, for issuance. Each series of preferred stock shall have such rights, preferences, privileges and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences, as may be determined by the Company’s board of directors (the “Board”).
	Rights Agreement
	On January 6, 2014, the Company’s Board declared a dividend of one preferred share purchase right (a “Right”) for each outstanding share of common stock, par value $0.01 per share, of the Company, to purchase one ten-thousandth of a share of newly designated Series A Junior Participating Preferred Stock, par value $0.01 per share, of the Company (the “Preferred Stock”), at a price of $40.00 per one ten-thousandth of a share of Preferred Stock, subject to adjustment as provided in the Rights Agreement described below. Stockholders of record at the close of business on January 17, 2014 (the “Record Date”) received the dividend. The description and terms of the Rights are set forth in a Rights Agreement, dated as of January 6, 2014, as the same may be amended from time to time (the “Rights Agreement”), between the Company and Computershare Trust Company N.A, as Rights Agent.
	The Rights Agreement became effective on January 6, 2014 (the “Effective Date”). Following the Effective Date, Rights will be issued in respect of all shares of the Company’s common stock issued after the Record Date and, subject to the terms described in the Rights Agreement, prior to the earliest of the Distribution Date (as defined in the Rights Agreement), the redemption of the Rights or the expiration of the Rights. A Distribution Date will occur upon the earlier of (i) 10 business days (or such later date as the Board shall determine) following a public announcement by the Company that a person or group of affiliated or associated persons (an “Acquiring Person”) has acquired beneficial ownership of 15% or more of the outstanding shares of common stock, other than as a result of repurchases of stock by the Company, certain inadvertent actions by institutional or certain other stockholders or beneficial ownership by certain Exempt Persons or (ii) 10 business days (or such later date as the Board shall determine) following the commencement of a tender offer or exchange offer that would result in a person or group becoming an Acquiring Person. An “Exempt Person” is any person or group which beneficially owned 15% or more of the common stock at the time of public announcement of the Rights Agreement unless and until such person or group acquires beneficial ownership of additional shares of common stock representing one percent or more of the Company’s common stock then outstanding.
	The Rights will expire at the next annual meeting of the Company’s stockholders, unless the Rights are earlier redeemed or exchanged by the Company, in each case as defined in the Rights Agreement.
	Common Stock Repurchases
	In April 2007, the Company’s Board approved a stock repurchase program that authorized the Company to repurchase up to $100 million of the Company’s common stock through transactions on the open market, in block trades or otherwise. In February 2008, the Company’s Board of Directors approved a $100 million increase in the authorized funds for the repurchase of the Company’s common stock. At December 31, 2013, there was $80.3 million available for future stock repurchases under the program. This stock repurchase program has no expiration date. During the years ended December 31, 2013, 2012 and 2011, no shares were repurchased under this program.
	Under some of the Company’s equity compensation plans, employees have the option or may be required to satisfy minimum withholding tax obligations by tendering to the Company a portion of the common stock received under the award. During the year ended December 31, 2011 (Restated), the Company received approximately 9,802 shares of its common stock in exchange for $0.1 million of minimum employee withholding liabilities paid by the Company. During the years ended December 31, 2013 and 2012, no such shares were repurchased.
	Stock Incentive Plans
	Under its stock incentive plans, the Company may grant stock awards or options to purchase the Company’s common stock to employees, officers, directors (subject to certain restrictions) and consultants, generally at the market price on the date of grant. Current option grants become exercisable over various periods, typically three to four years for employees and one year for non-employee directors, and have a maximum term of seven years. Restricted stock and restricted stock unit awards with time-based vesting typically vest over three to four years. Restricted stock unit awards with vesting based on performance conditions, market conditions, or a combination of performance or market conditions typically have a maximum term of approximately eleven years. Shares available for issuance under the Company’s Amended and Restated 2005 Stock Incentive Plan totaled 3,333,219 at December 31, 2013, including 523,233 shares that may alternatively be issued as awards of restricted stock or restricted stock units.
	The Company uses the Black-Scholes option pricing model to estimate the fair value of stock option grants with time-based vesting. The Black-Scholes model relies on a number of key assumptions to calculate estimated fair values. The assumed dividend yield of zero is based on the fact that the Company has never paid cash dividends and has no present intention to pay cash dividends and our current credit agreement precludes us from paying dividends. The expected stock-price volatility assumption is based on recent (six-month trailing) implied volatility calculations. These calculations are performed on exchange traded options of the Company’s common stock, based on the implied volatility of long-term (9- to 39-month term) exchange-traded options. The Company believes that using a forward-looking market-driven volatility assumption will result in the best estimate of expected volatility. The assumed risk-free interest rate is the U.S. Treasury security rate with a term equal to the expected life of the option. The assumed expected life is based on company-specific historical experience considering the exercise behavior of past grants and models the pattern of aggregate exercises.
	The fair value of restricted stock and restricted stock unit awards with time-based vesting is based on the intrinsic value of the awards at the date of grant, as the awards have a purchase price of $0.01 per share.
	The Company also issues stock option grants or restricted stock unit awards with vesting based on market conditions, specifically the Company’s stock price; performance conditions, generally the Company’s return on equity or operating margin; or a combination of performance or market conditions. The fair values and derived service periods for all grants that include vesting based on market conditions are estimated using the Monte Carlo valuation method. For stock option grants that include vesting based on performance conditions, the fair values are estimated using the Black-Scholes option pricing model. For restricted stock unit awards that include vesting based on performance conditions, the fair values are estimated based on the intrinsic values of the awards at the date of grant, as the awards have a purchase price of $0.01 per share. For stock option grants and restricted stock unit awards with vesting based on a combination of performance or market conditions, compensation costs are recorded based on the higher estimated grant-date fair value for each vesting tranche and factored for the estimated probability of achieving the performance goals. For each stock option grant and restricted stock award with vesting based on a combination of performance or market conditions where vesting will occur if either condition is met, the related compensation costs are recognized over the shorter of the derived service period or implicit service period.
	Information with respect to options granted under all stock option plans for the year ended December 31, 2013 was as follows:

	Options exercisable at December 31, 2013					2,488,278		$17.36	2.44	$31
	The performance-based stock options outstanding at December 31, 2013 will vest either upon the earlier of certain performance conditions being met or upon the Company’s stock price reaching certain amounts as defined in the agreements, or solely upon the achievement of a performance condition. The performance conditions are based upon the achievement of specified return on equity or operating margins, and the options are probable of vesting as of December 31, 2013. The stock options, however, will not become exercisable until the Company’s Board votes that the established performance conditions have been met. As of December 31, 2013, none of these performance-based options are exercisable.
	The following table sets forth the weighted-average key assumptions and fair value results for stock options granted during the years ended December 31, 2013, 2012 and 2011 (Restated):
			Year Ended December 31,

	During the years ended December 31, 2013 and 2012, the cash received from and the aggregate intrinsic value of stock options exercised was not material. The aggregate intrinsic value of stock options exercised during the year ended December 31, 2011 (Restated) was approximately $1.1 million, and the cash received from such exercises was approximately $2.2 million. The Company did not realize a material tax benefit from the tax deductions for stock option exercises during the years ended December 31, 2013, 2012 or 2011 (Restated).
	The fair value of restricted stock unit awards with time-based vesting is based on the intrinsic value of the awards at the date of grant.

	Expected to vest					297,751		$11.53	4.07	$2,424
	The performance-based restricted stock units outstanding at December 31, 2013 will vest either upon the earlier of certain performance conditions being met or upon the Company’s stock price reaching certain amounts as defined in the agreements, or solely upon the achievement of a performance condition. The performance conditions are based upon the achievement of specified return on equity or operating margins, and the restricted stock units are probable of vesting as of December 31, 2013. The restricted stock units, however, will not become exercisable until the Company’s Board votes that the established performance conditions have been met. As of December 31, 2013, none of these performance-based restricted stock units are vested.
	The following table sets forth the weighted-average key assumptions for restricted stock units with vesting based on market conditions or a combination of performance or market conditions granted during the year ended December 31, 2011 (Restated). There were no grants of restricted stock units with vesting based on market conditions or a combination of performance or market conditions during the years ended December 31, 2013 and 2012.

	The weighted-average grant date fair value of restricted stock units granted during the years ended December 31, 2012 and 2011 (Restated) was $10.95 and $21.36, respectively. The total fair value of restricted stock units vested during the years ended December 31, 2013, 2012, and 2011 (Restated) was $1.1 million, $2.3 million, and $4.2 million, respectively.
Employee Stock Purchase Plan
The Company’s Second Amended and Restated 1996 Employee Stock Purchase Plan (the “ESPP”) offers the Company’s shares for purchase at a price equal to 85% of the closing price on the applicable offering period termination date. Shares issued under the ESPP are considered compensatory. Accordingly, the Company is required to measure fair value and record compensation expense for share purchase rights granted under the ESPP. The Company last issued shares under the ESPP on January 31, 2013. On March 8, 2013, participation in the ESPP was suspended as a result of the restatement of the Company’s financial statements and its delays in financial reporting.
The Company uses the Black-Scholes option pricing model to calculate the fair value of shares issued under the ESPP. The Black-Scholes model relies on a number of key assumptions to calculate estimated fair values. The following table sets forth the weighted-average key assumptions and fair value results for shares issued under the ESPP during the years ended December 31, 2013, 2012 and 2011 (Restated):
	Year Ended December 31,
					2011
	2013		2012		(Restated)
Expected dividend yield	0.00%		0.00%		0.00%

Shares issued under the ESPP	27,936		142,658		124,219
Average price of shares issued	$6.29		$6.96		$9.71
A total of 441,913 shares remained available for issuance under the ESPP at December 31, 2013.
Stock-Based Compensation Expense
The Company estimates forfeiture rates at the time awards are made based on historical and estimated future turnover rates and applies these rates in the calculation of estimated compensation cost. The estimation of forfeiture rates includes a quarterly review of historical turnover rates and an update of the estimated forfeiture rates to be applied to employee classes for the calculation of stock-based compensation. Forfeiture rates for the calculation of stock-based compensation were estimated and applied based on three classes, non-employee directors, executive management staff and other employees. At December 31, 2013 and 2012, the Company’s annualized estimated forfeiture rates were 0% for non-employee director awards, 10% for executive management staff and 15% for other employee awards. Then-current estimated forfeiture rates are applied quarterly to all outstanding stock options and non-vested restricted stock awards, which may result in a revised estimate of compensation costs related to these stock-based grants.
Stock-based compensation was included in the following captions in the Company’s consolidated statements of operations for the years ended December 31, 2013, 2012 and 2011 (Restated), respectively (in thousands):
	Year Ended December 31,
									2011
	2013				2012				(Restated)
Cost of products revenues	$	360			$	410			$	487
Cost of services revenues	436				582				714
Research and development expenses	582				986				1,638
Marketing and selling expenses	1,778				3,754				4,306
General and administrative expenses	3,761				5,700				5,464
Total	$	6,917			$	11,432			$	12,609
Included in stock-based compensation expense for the years ended December 31, 2013, 2012, and 2011 (Restated) was compensation related to performance-based stock options and restricted stock units totaling $0.9 million, $2.7 million and $2.1 million, respectively, for awards that are probable of vesting.
As a result of the 2012 restructuring plan, the vesting of 121,875 stock option shares and 33,438 restricted stock unit shares were accelerated as set forth in the employment agreements for two of the Company’s former executives, resulting in $1.1 million in additional stock-based compensation recorded as marketing and selling expense during the year ended December 31, 2012. Similarly, as a result of our 2013 management transition, the vesting of 303,229 stock option shares and 72,267 restricted stock unit shares were accelerated as set forth in the employment agreements for four of the Company’s former executives, resulting in $2.2 million in additional stock-based compensation recorded primarily as general and administrative expense during the first quarter of the year ended December 31, 2013.
At December 31, 2013, there was $6.8 million of total unrecognized compensation cost, before forfeitures, related to non-vested stock-based compensation awards granted under the Company’s stock-based compensation plans. The Company expects this amount to be amortized approximately as follows: $4.5 million in 2014, $1.6 million in 2015 and $0.7 million in 2016. At December 31, 2013, the weighted-average recognition period of the unrecognized compensation cost was approximately 1.05 years.
If factors change and the Company employs different assumptions to estimate stock-based compensation expense in future periods, including changes in the probability of achieving performance conditions, or the Company decides to use a different valuation model, the stock-based compensation expense recognized in future periods may differ significantly from what has been recorded in the current period and could materially affect the Company’s operating income, net income and earnings per share. It may also result in a lack of comparability with other companies that use different models, methods and assumptions.

EMPLOYEE BENEFIT PLANS	'
	EMPLOYEE BENEFIT PLANS
	Employee Benefit Plans
	The Company has a defined contribution employee benefit plan under Section 401(k) of the U.S. Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”) covering substantially all U.S. employees. The 401(k) plan allows employees to make contributions up to a specified percentage of their compensation. The Company may, upon resolution by the Company’s board of directors, make discretionary contributions to the plan. The Company’s contributions to the plan totaled $2.2 million, $2.5 million and $2.9 million in 2013, 2012 and 2011 (Restated), respectively.
	In addition, the Company has various retirement and post-employment plans covering certain international employees. Certain of the plans allow the Company to match employee contributions up to a specified percentage as defined by the plans. The Company’s contributions to these plans totaled $1.2 million, $1.4 million and $1.4 million in 2013, 2012 and 2011 (Restated), respectively.
	Deferred Compensation Plans
	The Company’s board of directors has approved a nonqualified deferred compensation plan (the “Deferred Plan”). The Deferred Plan covers senior management and members of the Board. The plan provides for a trust to which participants can contribute varying percentages or amounts of eligible compensation for deferred payment. Payouts are generally made upon termination of employment with the Company. The benefits payable under the Deferred Plan represent an unfunded and unsecured contractual obligation of the Company to pay the value of the deferred compensation in the future, adjusted to reflect the trust’s investment performance. The assets of the trust, as well as the corresponding obligations, were approximately $1.3 million and $1.1 million at December 31, 2013 and 2012, respectively, and were recorded in “other current assets” and “accrued compensation and benefits” at those dates. In November 2013, the Board determined not to offer senior management or the members of the Board the opportunity to participate in the Deferred Plan in 2014 due to the restatement of the Company’s financial statements and its delays in financial reporting.
	In connection with the acquisition of a business in 2010, the Company assumed the assets and liabilities of a deferred compensation arrangement for a single individual in Germany. The arrangement represents a contractual obligation of the Company to pay a fixed euro amount for a period specified in the contract. At December 31, 2013 and 2012, the Company’s assets and liabilities related to the arrangement consisted of assets recorded in “other long-term assets” of $0.6 million for each year, representing the value of related insurance contracts, and liabilities recorded as long-term liabilities of $3.9 million for each year, representing the actuarial present value of the estimated benefits to be paid under the contract

	The cumulative amount of undistributed earnings of foreign subsidiaries, which is intended to be indefinitely reinvested and for which U.S. income taxes have not been provided, totaled approximately $35 million at December 31, 2013. The Company does not have any plans to repatriate these earnings because the underlying cash will be used to fund the ongoing operations of the foreign subsidiaries. The additional taxes that might be payable upon repatriation of foreign earnings are not significant.
	Net deferred tax assets (liabilities) consisted of the following at December 31, 2013 and 2012 (in thousands):

	Long-term deferred tax liabilities, net	(565		)		(713		)
	Net deferred tax assets	$	2,358			$	2,495
	Deferred tax assets and liabilities reflect the net tax effects of the tax credits and net operating loss carryforwards and the temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The ultimate realization of the net deferred tax assets is dependent upon the generation of sufficient future taxable income in the applicable tax jurisdictions. Based on the level of the deferred tax assets at December 31, 2013 and 2012 and the level of historical U.S. losses, management has determined that the uncertainty regarding the realization of these assets warranted a full valuation allowance at December 31, 2013 and 2012. The change in the valuation allowance totaled $0.5 million and $(35.3) million and $(29.6) million for the years ended December 31, 2013, 2012 and 2011, respectively.
	For U.S. federal and state income tax purposes at December 31, 2013, the Company had tax credit carryforwards of $48.1 million, which will expire between 2016 and 2033, and net operating loss carryforwards of $573.6 million, which will expire between 2019 and 2033. The federal net operating loss and tax credit amounts are subject to annual limitations under Section 382 change of ownership rules of the Internal Revenue Code. The Company completed an assessment at December 31, 2013 regarding whether there may have been a Section 382 ownership change and concluded that it is more likely than not that none of the Company’s net operating loss and tax credit amounts are subject to any Section 382 limitation.
	Additionally, the Company has foreign net operating loss carryforwards of $41.4 million and tax credit carryforwards of $3.9 million that begin to expire in 2019. The Company has determined there is uncertainty regarding the realization of a portion of these assets and has recorded a valuation allowance against $36.5 million of net operating losses and $3.9 million of tax credits at December 31, 2013.
	The Company’s assessment of the valuation allowance on the U.S. and foreign deferred tax assets could change in the future based on its levels of pre-tax income and other tax related adjustments. Removal of the valuation allowance in whole or in part would result in a non-cash reduction in income tax expense during the period of removal.
	Excluded from the above deferred tax schedule at December 31, 2013 are tax assets totaling $33.0 million resulting from the exercise of employee stock options, because recognition of these assets will occur upon utilization of these deferred tax assets to reduce taxes payable and will result in a credit to additional paid-in capital within stockholders’ equity rather than the provision for income taxes.
	The following table sets forth a reconciliation of the Company’s income tax provision (benefit) to the statutory U.S. federal tax rate for the years ended December 31, 2013, 2012 and 2011 (Restated):
		Year Ended December 31,
								2011
		2013			2012			(Restated)
	Statutory rate	35	%		35	%		35	%
	Tax credits	(6.2	)%		(1.2	)%		(0.6	)%
	Foreign operations	(43.8	)%		(12.7	)%		(8.8	)%
	Non-deductible expenses and other	2.1	%		1.4	%		0.9	%
	Increase (decrease) in valuation allowance	25.1	%		(14.6	)%		(26.1	)%
	Effective tax rate	12.2	%		7.9	%		0.4	%
A tax position must be more likely than not to be sustained before being recognized in the financial statements. It also requires the accrual of interest and penalties as applicable on unrecognized tax positions. The Company is disclosing unrecognized tax benefits primarily related to the foreign tax implications of the restatement adjustments. The unrecognized tax benefits did not have an impact on the effective tax rate because the Company maintains a full valuation allowance on the related loss carryforwards. At December 31, 2011 (Restated), the Company’s unrecognized tax benefits and related accrued interest and penalties totaled $20.2 million, of which $0.9 million would affect the Company’s income tax provision and effective tax rate if recognized. At December 31, 2012, the Company’s unrecognized tax benefits and related accrued interest and penalties totaled $22.6 million, of which $0.9 million would affect the Company’s effective tax rate if recognized. At December 31, 2013, the Company’s unrecognized tax benefits and related accrued interest and penalties totaled $24.7 million, of which $0.8 million would affect the Company’s income tax provision and effective tax rate if recognized. The foreign tax authorities are aware of the uncertain tax position related to the restatement adjustments and the Company believes that it is reasonably possible that the foreign tax authorities will conclude on this matter by December 31, 2014 resulting in a decrease of up to $23.9 million in unrecognized tax benefits and a change in deferred tax assets that carry a full valuation allowance.
The following table sets forth a reconciliation of the beginning and ending amounts of unrecognized tax benefits, excluding the impact of interest and penalties, for the years ended December 31, 2013, 2012 and 2011 (Restated) (in thousands):
Unrecognized tax benefits at January 1, 2011 (Restated)	$	18,424
Increases for tax positions taken during a prior period	3,056
Decreases related to settlements	(900		)
Decreases related to the lapse of applicable statutes of limitations	(400		)
Unrecognized tax benefits at December 31, 2011 (Restated)	20,180
Increases for tax positions taken during a prior period	3,198
Decreases related to the lapse of applicable statutes of limitations	(749		)
Unrecognized tax benefits at December 31, 2012	22,629
Increases for tax positions taken during a prior period	2,205
Decreases related to the lapse of applicable statutes of limitations	(105		)
Unrecognized tax benefits at December 31, 2013	$	24,729
The Company recognizes interest and penalties related to uncertain tax positions in income tax expense. Accrued interest and penalties related to uncertain tax positions at December 31, 2013 and 2012 were not material.
The tax years 2006 through 2013 remain open to examination by taxing authorities in the jurisdictions in which the Company operates.
On September 13, 2013, the U.S. Treasury Department released final income tax regulations on the deduction and capitalization of expenditures related to tangible property. These final regulations apply to tax years beginning on or after January 1, 2014. The tangible property regulations will require the Company to make tax accounting method changes as of January 1, 2014; however, management does not anticipate the impact of these changes to be material to the Company’s consolidated financial position or results of operations.

	RESTRUCTURING COSTS AND ACCRUALS
	2013 Restructuring Actions
	In June 2013, the Company’s leadership evaluated the marketing and selling teams and, in an effort to better align sales resources with the Company’s strategic goals and enhance its global account team approach, eliminated 31 positions. As a result, the Company recognized related restructuring costs of $1.7 million in 2013.
	During November and December 2013, the Company’s executive management team identified opportunities to lower costs in the supply and hardware technology group by eliminating 29 positions in hardware shared services and 15 positions in the supply and technology group. Additionally, an engineering reorganization at the same time resulted in the elimination of four engineering positions. As a result, the Company recognized $1.7 million of related restructuring costs in November and December 2013.
	2012 Restructuring Plan
	In June 2012, the Company committed to a series of strategic actions (the “2012 Plan”) to focus on its Broadcast and Media market and Video and Audio Post and Professional market and to drive improved operating performance. These actions included the divestiture of certain of the Company’s consumer-focused product lines, a rationalization of the business operations and a reduction in force. Actions under the plan included the elimination of approximately 280 positions in June 2012, the abandonment of one of the Company’s facilities in Burlington, Massachusetts and the partial abandonment of facilities in Mountain View and Daly City, California, in September 2012. During 2012, the Company recorded restructuring charges of $13.9 million related to severance costs and $8.6 million for the closure or partial closure of facilities, which included non-cash amounts of $1.4 million for fixed asset write-offs and $1.0 million for deferred rent liability write-offs during 2012.
	During 2013, the Company recorded $0.1 million in additional severance costs and revisions totaling $1.8 million resulting from sublease assumption changes and other costs related to the abandoned facilities under the 2012 Plan. The Company substantially completed all actions under the 2012 Plan prior to December 31, 2012.
	2011 Restructuring Plan
	In October 2011, the Company committed to a restructuring plan (the “2011 Plan”) intended to improve operational efficiencies. Actions under the 2011 Plan included the elimination of approximately 210 positions and the closure of the Company’s facility in Irwindale, California. During 2011, the Company recorded $8.9 million related to severance costs and $0.2 million related to the closure of the Irwindale facility. During 2012, the Company recorded restructuring recoveries of $0.3 million as a result of revised severance estimates. There is no remaining accrual balance related to this plan at December 31, 2013, and no further restructuring actions are anticipated under this plan.
	2010 Restructuring Plans
	In December 2010, the Company initiated a worldwide restructuring plan (the “2010 Plan”) designed to better align financial and human resources in accordance with its strategic plans.  During 2011, the Company recorded restructuring expense recoveries of $3.2 million as a result of revised severance estimates, as well as $0.7 million in additional costs related to the closure of a facility in Germany. During 2012, the Company recorded revisions totaling $0.7 million as a result of sublease assumption changes for the partial abandonment of a facility in Daly City, California, under the 2010 Plan. The remaining accrual balance of $0.5 million at December 31, 2013 is related to the closure of part of the Company’s Daly City, California facility. No further restructuring actions are anticipated under this plan.
	2008 Restructuring Plans
	In October 2008, the Company initiated a company-wide restructuring plan (the “2008 Plan”). During 2012, the Company recorded revisions totaling $1.8 million as a result of sublease assumption changes for the partial abandonment of a facility in Daly City, California, under the 2008 Plan. The remaining accrual balance of $2.2 million at December 31, 2013 is related to the closure of part of the Company’s Daly City, California and Dublin, Ireland facilities. No further restructuring actions are anticipated under this plan.

	The employee-related accruals at December 31, 2013 and 2012 represent severance and outplacement costs to former employees that will be paid out during the year ended December 31, 2014, and are, therefore, included in the caption “accrued expenses and other current liabilities” in the Company’s consolidated balance sheet at December 31, 2013 and 2012.
	The facilities-related accruals at December 31, 2013 and 2012 represent contractual lease payments, net of estimated sublease income, on space vacated as part of the Company’s restructuring actions. The leases, and payments against the amounts accrued, extend through 2021 unless the Company is able to negotiate earlier terminations. Of the total facilities-related accruals, $3.8 million was included in the caption “accrued expenses and other current liabilities” and $2.3 million was included in the caption “other long-term liabilities” in the Company’s consolidated balance sheet at December 31, 2013. At December 31, 2012, $6.3 million was included in the caption “accrued expenses and other current liabilities” and $5.1 million was included in the caption “other long-term liabilities.”

SEGMENT INFORMATION	'
	SEGMENT INFORMATION
	The Company provides digital media content-creation products and solutions for film, video, audio and broadcast professionals, as well as artists and musicians, which the Company classifies as two types, video and audio. The Company also classifies all its maintenance, professional services and training revenues as services revenues. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company’s evaluation of the discrete financial information that is regularly reviewed by the chief operating decision makers determined that in 2013, 2012 and 2011 the Company had only one operating segment. Specifically, the Company does not internally measure profitability based upon video, audio, or service revenue.
	The Company’s video products include hardware and software solutions designed to improve the productivity of video and film editors and broadcasters by enabling them to edit video, film and sound; manage media assets; and automate workflows. Professional video creative software and hardware products include the Media Composer product line used to edit television programs, commercials and films; the NewsCutter and Instinct editors designed for news production; and Avid Symphony Nitris DX and Avid DS, which are used during post production. Video products also include Avid ISIS shared storage and Interplay workflow solutions that provide complete network, storage and database solutions based on the Company’s Avid Unity MediaNetwork technology and enable users to simultaneously share and manage media assets throughout a project or organization.
	The Company’s audio products include digital audio software and workstation solutions, control surfaces, live sound systems and notation software that provide music creation; audio recording, editing, and mixing; and live performance solutions. Audio products include Pro Tools digital audio software and workstation solutions to facilitate the audio production process, including music and sound creation, recording, editing, signal processing, integrated surround mixing and mastering, and reference video playback. Audio products also include the ICON (Integrated Console System) systems, including the D-Control and D-Command control surfaces, the VENUE live-sound mixing consoles and Sibelius-branded notation software.
	The Company’s services revenues are primarily derived from the sale of maintenance contracts and professional service and the recognition of revenues for Implied Maintenance Release PCS. The Company provides online and telephone support and access to software upgrades for customers whose products are under warranty or covered by a maintenance contract. The Company’s professional services team provides installation, integration, planning, consulting and training services.

CREDIT AGREEMENT	'
	CREDIT AGREEMENT
	On October 1, 2010, Avid Technology, Inc. and certain of its subsidiaries (the “Borrowers”) entered into a credit agreement with Wells Fargo that established two revolving credit facilities with combined maximum availability of up to $60 million for borrowings and letter of credit guarantees (the “Credit Agreement”). The actual amount of credit available to the Borrowers will vary depending upon changes in the level of the respective accounts receivable and inventory, and is subject to other terms and conditions that are more specifically described in the Credit Agreement. On August 29, 2014, the Company entered into an amendment to its Credit Agreement with Wells Fargo that extended the maturity date for the credit facilities from October 1, 2014 to October 1, 2015.
	The amended Credit Agreement contains customary representations and warranties, covenants, mandatory prepayments, and events of default under which the Borrowers’ payment obligations may be accelerated, including guarantees and liens on substantially all of the Borrowers’ assets to secure their obligations under the Credit Agreement. The Credit Agreement prohibits the Company from declaring or paying any cash dividends. The Credit Agreement requires that Avid Technology, Inc. (“Avid Technology”) maintain liquidity (comprised of unused availability under its portion of the credit facilities plus certain unrestricted cash and cash equivalents) of $10.0 million, at least $5.0 million of which must be from unused availability under its portion of the credit facilities. The Amendment further limits the Company’s ability to access borrowings under the credit facilities if EBITDA (as defined in the Amendment) of $33.8 million is not achieved for the year ending December 31, 2014, or capital expenditures (as defined in the Amendment) exceed $16.0 million for the year ending December 31, 2014. In addition, its subsidiary, Avid Technology International B.V. (“Avid Europe”), is required to maintain liquidity (comprised of unused availability under Avid Europe's portion of the credit facilities plus certain unrestricted cash and cash equivalents) of $5.0 million, at least $2.5 million of which must be from unused availability under Avid Europe's portion of the credit facilities. Interest accrues on outstanding borrowings under the credit facilities at a rate of either LIBOR plus 2.75% or a base rate (as defined in the Credit Agreement) plus 1.75%, at the option of Avid Technology or Avid Europe, as applicable. The Borrowers must also pay Wells Fargo a monthly unused line fee at a rate of 0.625% per annum. Any borrowings under the Credit Agreement are secured by a lien on substantially all the Borrowers’ assets.
	The Company incurs certain loan fees and costs associated with its credit facilities. Such costs are capitalized as deferred borrowing costs and amortized as interest expense on a straight-line basis over the term of the Credit Agreement. At December 31, 2013, the balance of the Company’s deferred borrowing costs was $0.2 million, net of accumulated amortization of $1.0 million, and at December 31, 2012, the balance of the deferred borrowing costs was $0.5 million, net of accumulated amortization of $0.7 million.
	During the first quarter of 2012, Avid Technology borrowed $1.0 million against the credit facilities to meet certain short-term cash requirements, all of which was repaid during the first quarter of 2012. During the third quarter of 2012, Avid Technology and Avid Europe borrowed and repaid $10.0 million and $3.0 million, respectively, against the credit facilities, primarily to facilitate the settlement of certain intercompany balances and payment of intercompany dividends. At December 31, 2013, Avid Technology and Avid Europe had letters of credit guaranteed under the credit facilities of $3.4 million and $1.7 million, respectively. At December 31, 2013, Avid Technology and Avid Europe had available borrowings under the credit facilities of approximately $18.4 million and $15.5 million, respectively, after taking into consideration the outstanding letters of credit and related liquidity covenant.
	Other than letters of credit guaranteed under the credit facilities, the Company had no outstanding borrowings under the credit facilities at December 31, 2013 and 2012.
	At July 31, 2014, the Company had outstanding borrowings of $10.0 million under the Credit Agreement, and the remaining availability totaled $15.6 million.

BUSINESS_AND_SUMMARY_OF_SIGNIF1

BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Business and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2013
Foreign Currency Transactions and Translations Policy [Policy Text Block]	'
	Translation of Foreign Currencies
	The functional currency of each of the Company’s foreign subsidiaries is the local currency, except for the Irish manufacturing branch whose functional currency is the U.S. dollar due to the extensive interrelationship of the operations of the Irish branch and the U.S. parent and the high volume of intercompany transactions between that branch and the parent. The assets and liabilities of the subsidiaries whose functional currencies are other than the U.S. dollar are translated into U.S. dollars at the current exchange rate in effect at the balance sheet date. Income and expense items for these entities are translated using rates that approximate those in effect during the period. Cumulative translation adjustments are included in accumulated other comprehensive income (loss), which is reflected as a separate component of stockholders’ deficit. The Company does not record tax provisions or benefits for the net changes in the foreign currency translation adjustment as the Company intends to permanently reinvest undistributed earnings in its foreign subsidiaries.
	The U.S. parent company and its Irish manufacturing branch, both of whose functional currency is the U.S. dollar, carry certain monetary assets and liabilities denominated in currencies other than the U.S. dollar. These assets and liabilities typically include cash, accounts receivable and intercompany operating balances denominated in foreign currencies. These assets and liabilities are remeasured into the U.S. dollar at the current exchange rate in effect at the balance sheet date. Foreign currency transaction and remeasurement gains and losses are included within marketing and selling expenses in the results of operations. See Note D for the net foreign exchange gains and losses recorded in the Company’s statements of operations during the years ended December 31, 2013, 2012 and 2011 (Restated) that resulted from the gains and losses on Company’s foreign currency contracts and the revaluation of the related hedged items.
	The U.S. parent company and various other wholly owned subsidiaries have long-term intercompany loan balances denominated in foreign currencies that are remeasured into the U.S. dollar at the current exchange rate in effect at the balance sheet date. Such loan balances are not expected to be settled in the foreseeable future. Any gains and losses relating to these loans are included in the accumulated other comprehensive income (loss), which is reflected as a separate component of stockholders’ deficit.
Consolidation, Policy [Policy Text Block]	'
	Principles of Consolidation
	The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. Intercompany balances and transactions have been eliminated.
	Basis of Presentation
	The Company’s 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 disclosures of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reported periods. Actual results could differ from the Company’s estimates.
Income Tax, Policy [Policy Text Block]	'
	Income Taxes
	The Company accounts for income taxes using an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Company’s financial statements or tax returns. The Company records deferred tax assets and liabilities based on the net tax effects of tax credits, operating loss carryforwards and temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes compared to the amounts used for income tax purposes. Deferred tax assets are regularly reviewed for recoverability with consideration for such factors as historical losses, projected future taxable income and the expected timing of the reversals of existing temporary differences. The Company is required to record a valuation allowance when it is more likely than not that some portion or all of the deferred tax assets will not be realized. Based on the magnitude of the Company’s deferred tax assets at December 31, 2013 and the historical U.S. losses, the Company has determined that the uncertainty regarding the realization of these assets is sufficient to warrant the need for a full valuation allowance against its U.S. net deferred tax assets. The Company has also determined that a valuation allowance is warranted on a portion of its foreign deferred tax assets.
Research, Development, and Computer Software, Policy [Policy Text Block]	'
	Research and Development Costs
	Research and development costs are expensed as incurred, except for costs that qualify for capitalization. Development costs for software to be sold that are incurred subsequent to the establishment of technological feasibility, but prior to the general release of the product, are capitalized. Upon general release, these costs are amortized using the straight-line method over the expected life of the related products, generally 12 to 36 months. The straight-line method generally results in approximately the same amount of expense as that calculated using the ratio that current period gross product revenues bear to total anticipated gross product revenues. The Company periodically evaluates the assets, considering a number of business and economic factors, to determine if an impairment exits.
Discontinued Operations, Policy [Policy Text Block]	'
	Discontinued Operations
	The Company classifies the assets and liabilities of a business as held-for-sale when management approves and commits to a formal plan of sale and it is probable that the sale will be completed. The carrying value of the net assets of the business held-for-sale are then recorded at the lower of their carrying value or fair market value, less costs to sell. As discussed in Note I, the Company completed the sales of the consumer audio and consumer video product lines in the third quarter of 2012. The operations of divested businesses have been reflected as discontinued operations for all periods presented in these consolidated financial statements.
Intangible Assets, Finite-Lived, Policy [Policy Text Block]	'
	Intangible Assets
	Intangible assets consist of acquired and internally developed assets. Acquired intangible assets include customer relationships, developed technology, trade names and non-compete agreements from acquisitions. Internally developed assets consist primarily of various technologies that form the basis of products sold to customers. Costs are capitalized from when technological feasibility is established up until when the product is available for general release. Intangible assets are determined to have either finite or indefinite lives. For finite-lived intangible assets amortization is straight-line over the estimated useful lives of such assets, which are generally two years to twelve years. Straight-line amortization is used because the Company cannot reliably determine a discernible pattern over which the economic benefits would be realized. The Company does not have any indefinite-lived intangible assets. Intangible assets are tested for impairment when events and circumstances indicate there is an impairment. The impairment test involves comparing the sum of undiscounted cash flows to the carrying value as of the measurement date. Impairment occurs when the carrying value of the assets exceeds the sum of undiscounted cash flows. Impairment is then measured as the difference between the carrying value and fair value determined using a discounted cash flow method. In estimating the fair value using a discounted cash flow method, the Company uses assumptions that include forecast revenues, gross margins, operating profit margins, growth rates and long term discount rates, all of which require significant judgment by management. Changes to these assumptions could affect the estimated fair value of the intangible asset and could result in an impairment charge in future.
Derivatives, Policy [Policy Text Block]	'
	Foreign Currency Risk
	The Company has significant international operations and, therefore, the Company’s revenues, earnings, cash flows and financial position are exposed to foreign currency risk from foreign-currency-denominated receivables, payables, sales and expense transactions, and net investments in foreign operations. The Company derives more than half of its revenues from customers outside the United States. This business is, for the most part, transacted through international subsidiaries and generally in the currency of the end-user customers. Therefore, the Company is exposed to the risks that changes in foreign currency could adversely affect its revenues, net income, cash flow and financial position. The Company uses derivatives in the form of foreign currency contracts to manage its short-term exposures to fluctuations in the foreign currency exchange rates that exist as part of its ongoing international business operations. The Company does not enter into any derivative instruments for trading or speculative purposes.
	The Company records all foreign currency contract derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as hedges of the exposure to changes in the fair value of an asset, liability or firm commitment attributable to a particular risk are considered fair value hedges. Derivatives designated and qualifying as hedges of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. Under hedge accounting, the determination of hedge effectiveness is dependent upon whether the gain or loss on the hedging derivative is highly effective in offsetting the gain or loss in the value of the item being hedged.
Cash and Cash Equivalents, Policy [Policy Text Block]	'
	Cash, Cash Equivalents and Marketable Securities
	Cash equivalents consist primarily of commercial paper, money market investments and certificates of deposit. The Company considers all debt instruments purchased with an original maturity of three months or less to be cash equivalents. Marketable securities, have historically consisted of certificates of deposit, commercial paper, asset-backed securities, discount notes, and corporate, municipal, agency and foreign bonds. The Company generally invests in securities that mature within one year from the date of purchase. The Company classifies its cash equivalents and marketable securities as “available for sale” and reports them at fair value, with unrealized gains and losses excluded from earnings and reported as an adjustment to other comprehensive income (loss), which is reflected as a separate component of stockholders’ deficit. Amortization or accretion of premium or discount is included in interest income (expense) in the results of operations. Other than those investments held in the Company’s deferred compensation plan, the Company held no available for sale securities classified as either cash equivalents or marketable securities at December 31, 2013 or 2012.
	Cash equivalents and marketable securities, including money market investments and mutual funds accounted for as trading securities, held in the Company’s deferred compensation plan are reported at fair value using quoted prices with the gains and losses included as other income (expense) in the Company’s statement of operations. Realized gains and losses from the Company’s deferred compensation plans were not material for the years ended December 31, 2013, 2012 and 2011 (Restated).
Concentration of credit risk [Policy Text Block]	'
	Concentration of Credit Risk
	Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents, foreign currency contracts and accounts receivable. The Company may place its excess cash in marketable investment grade securities and uses foreign currency contracts to manage certain of its short-term exposures to fluctuations in foreign currency exchange rates. The Company places its cash and cash equivalents and foreign currency contracts with financial institutions that management believes to be of high credit quality, and, generally, there are no significant concentrations in any one issuer of debt securities. Concentrations of credit risk with respect to trade receivables are limited due to the large number of customers that make up the Company’s customer base and their dispersion across different regions. No individual customer accounted for 10% or more of the Company’s net revenues or net accounts receivable in the periods presented.
Inventory, Policy [Policy Text Block]	'
	Inventories
	Inventories are stated at the lower of cost (determined on a first-in, first-out basis) or market value. Management regularly reviews inventory quantities on hand and writes down inventory to its realizable value to reflect estimated obsolescence or lack of marketability based on assumptions about future inventory demand and market conditions. Inventory in the digital-media market, including the Company’s inventory, is subject to rapid technological change or obsolescence; therefore, utilization of existing inventory may differ from the Company’s estimates.
Property, Plant and Equipment, Policy [Policy Text Block]	'
	Property and Equipment
	Property and equipment is recorded at cost and depreciated using the straight-line method over the estimated useful life of the asset. The Company typically depreciates its property and equipment using the following minimum and maximum useful lives:
			Depreciable Life (years)
			Minimum		Maximum
	Computer and video equipment and software		2		5
	Manufacturing tooling and testbeds		3		5
	Office equipment		3		5
	Furniture, fixtures and other		3		8
	Leasehold improvements are amortized over the shorter of the useful life of the improvement or the remaining term of the lease. Expenditures for maintenance and repairs are expensed as incurred. Upon retirement or other disposition of assets, the cost and related accumulated depreciation are eliminated from the accounts and the resulting gain or loss is reflected in other income (expense) in the results of operations.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	'
	Long-Lived Assets
	The Company periodically evaluates its long-lived assets for events and circumstances that indicate a potential impairment. A long-lived asset is assessed for impairment when the undiscounted expected future cash flows derived from that asset are less than its carrying value. The cash flows used for this analysis take into consideration a number of factors including past operating results, budgets and economic projections, market trends and product development cycles. The amount of any impairment would be equal to the difference between the estimated fair value of the asset, based on a discounted cash flow analysis, and its carrying value.
Advertising Costs, Policy [Policy Text Block]	'
	Advertising Expenses
	All advertising costs are expensed as incurred and are classified as marketing and selling expenses. Advertising expenses during 2013, 2012 and 2011 (Restated) were $1.8 million, $3.1 million and $3.8 million, respectively.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	'
	Accounting for Stock-Based Compensation
	The Company’s stock-based employee compensation plans allow the Company to grant stock awards, options, or other equity-based instruments, or a combination thereof, as part of its overall compensation strategy. For stock-based awards granted, the Company records stock-based compensation cost based on the grant date fair value over the requisite service periods for the individual awards, which generally equal the vesting periods. The vesting of stock-based award grants may be based on time, performance conditions, market conditions, or a combination of performance or market conditions.
Standard Product Warranty, Policy [Policy Text Block]	'
	Product Warranties
	The Company provides warranties on externally sourced and internally developed hardware. The warranty period for all of the Company’s products is generally 90 days to one year, but can extend up to five years depending on the manufacturer’s warranty or local law. For internally developed hardware and in cases where the warranty granted to customers for externally sourced hardware is greater than that provided by the manufacturer, the Company records an accrual for the related liability based on historical trends and actual material and labor costs. At the end of each quarter, the Company reevaluates its estimates to assess the adequacy of the recorded warranty liabilities and adjusts the accrued amounts accordingly.
Earnings Per Share, Policy [Policy Text Block]	'
	Computation of Net Income Per Share
	Net income per share is presented for both basic earnings per share (“Basic EPS”) and diluted earnings per share (“Diluted EPS”). Basic EPS is based on the weighted-average number of common shares outstanding during the period, excluding non-vested restricted stock held by employees. Diluted EPS is based on the weighted-average number of common and potential common shares outstanding during the period. Potential common shares result from the assumed exercise of outstanding stock options and non-vested restricted stock and restricted stock units, the proceeds and remaining unrecorded compensation expense of which are then assumed to have been used to repurchase outstanding common stock using the treasury stock method. For periods when the Company reports a loss, all potential common stock is considered anti-dilutive. For periods when the Company reports net income, potential common shares with combined purchase prices and unamortized compensation costs in excess of the Company’s average common stock fair value for the related period or that are contingently issuable are considered anti-dilutive. The contingently issuable potential common shares result from certain stock options and restricted stock units granted to the Company’s executive officers that vest based on performance conditions, market conditions, or a combination of performance or market conditions (see Notes C and M).
New Accounting Pronouncements, Policy [Policy Text Block]	'
	Recent Accounting Pronouncements To Be Adopted
	On May 28, 2014, the Financial Accounting Standards Board (the “FASB”) and the International Accounting Standards Board (the “IASB”) issued substantially converged final standards on revenue recognition. The FASB's Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606), was issued in three parts: (a) Section A, “Summary and Amendments That Create Revenue from Contracts with Customers (Topic 606) and Other Assets and Deferred Costs-Contracts with Customers (Subtopic 340-40),” (b) Section B, “Conforming Amendments to Other Topics and Subtopics in the Codification and Status Tables” and (c) Section C, “Background Information and Basis for Conclusions.” The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance.
	The new revenue recognition guidance becomes effective for the Company on January 1, 2017, and early adoption is not permitted. Entities have the option of using either a full retrospective or a modified approach to adopt the guidance in the ASU.  The Company has not yet selected a transition method and is currently evaluating the effect that the updated standard will have on its consolidated financial statements and related disclosures.
Subsequent Events, Policy [Policy Text Block]	'
	Subsequent Events
	On October 1, 2010, Avid Technology, Inc. and certain of its subsidiaries (the “Borrowers”) entered into a credit agreement with Wells Fargo Capital Finance LLC (“Wells Fargo”) that established two revolving credit facilities with combined maximum availability of up to $60 million for borrowings and letter of credit guarantees (the “Credit Agreement”). On August 29, 2014, the Company entered into an amendment (the “Amendment”) to its Credit Agreement with Wells Fargo. The Amendment (i) extended the maturity of the Credit Agreement from October 1, 2014 to October 1, 2015, (ii) changed the maximum amounts available under each of the revolving credit facilities, and (iii) added certain financial covenants, as described below.
	Under the Amendment, the maximum amount available for Avid Technology, Inc., (“Avid Technology”) was increased to $45 million (from $40 million) and the maximum amount available for its subsidiary Avid Technology International B.V. (“Avid Europe”) was decreased to $15 million (from $20 million). The maximum amount available under the combined credit facilities continues to be $60 million, subject to certain limitations on borrowing and other terms and conditions as provided in the Credit Agreement described in Note R.
	The Amendment further limits the Company’s ability to access borrowings under the credit facilities if (i) EBITDA (as defined in the Amendment) of $33.8 million is not achieved for the year ending December 31, 2014, or (ii) capital expenditures (as defined in the Amendment) exceed $16.0 million for the year ending December 31, 2014.
	The Company evaluated subsequent events through the date of issuance of these consolidated financial statements and, except for the subsequent events disclosed above and in Notes L, M and R, no other recognized or unrecognized subsequent events required recognition or disclosure in these financial statements.
Revenue Recognition, Policy [Policy Text Block]	'
	Revenue Recognition
	General
	The Company commences revenue recognition when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable and collection is reasonably assured. Generally, the products the Company sells do not require significant production, modification or customization. Installation of the Company’s products is generally routine, consists of implementation and configuration and does not have to be performed by Avid.
	The Company often receives multiple purchase orders or contracts from a single customer or a group of related customers that are evaluated to determine if they are, in effect, part of a single arrangement. In situations when the Company has concluded that two or more orders with the same customer are so closely related that they are, in effect, parts of a single arrangement, the Company accounts for those orders as a single arrangement for revenue recognition purposes. In other circumstances, when the Company has concluded that two or more orders with the same customer are independent buying decisions, such as an earlier purchase of a product and a subsequent purchase of a software upgrade or maintenance contract, the Company accounts for those orders as separate arrangements for revenue recognition purposes.
	For many of the Company’s products, there has been an ongoing practice of the Company making available at no charge to customers minor feature and compatibility enhancements as well as bug fixes on a when-and-if-available basis (collectively, “Software Updates”) for a period of time after initial sales to end users. The implicit obligation to make such Software Updates available to customers over a period of time represents implied post-contract customer support, which is deemed to be a deliverable in each arrangement and is accounted for as a separate element (referred to by the Company as “Implied Maintenance Release PCS”).
	The Company enters into certain contractual arrangements that have multiple elements, one or more of which may be delivered subsequent to the delivery of other elements. These multiple-deliverable arrangements may include products, support, training, professional services and Implied Maintenance Release PCS. In accordance with Accounting Standards Update (“ASU”) No. 2009-13, Multiple-Deliverable Revenue Arrangements, an amendment to ASC Topic 605 (“ASU No. 2009-13”) for these multiple-element arrangements, the Company allocates revenue to each deliverable of the arrangement based on the relative selling prices of the deliverables. In such circumstances, the Company first determines the selling price of each deliverable based on (i) vendor-specific objective evidence (“VSOE”) of fair value, if that exists; (ii) third-party evidence of selling price (“TPE”) when VSOE does not exist; or (iii) best estimate of the selling price (“BESP”) when neither VSOE nor TPE exists. Revenue is then allocated to the non-software deliverables as a group and to the software deliverables as a group using the relative selling prices of each of the deliverables in the arrangement based on the selling price hierarchy. The Company's process for determining BESP for deliverables for which VSOE or TPE does not exist involves significant management judgment. In determining BESP for each deliverable where it is required, the Company considers a number of data points, including:
	•	the pricing established by management when setting prices for deliverables that are intended to be sold on a standalone basis;
	•	contractually stated prices for deliverables that are intended to be sold on a standalone basis;
	•	the pricing of standalone sales that may not qualify as VSOE of fair value due to limited volumes or variation in prices; and
	•	other pricing factors, such as the geographical region in which products are sold and expected discounts based on the customer size and type.
	In determining a BESP for Implied Maintenance Release PCS, which the Company has never sold separately, management considers (i) the service period for the Implied Maintenance Release PCS, (ii) the differential in value of the Implied Maintenance Release PCS deliverable compared to a full support contract, (iii) the likely list price that would have resulted from the Company’s established pricing practices had the deliverable been offered separately, and (iv) the prices a customer would likely be willing to pay.
	The Company estimates service period of Implied Maintenance Release PCS based on the length of time the product version purchased by the customer is planned to be supported with Software Updates. If facts and circumstances indicate that the original deemed service period of Implied Maintenance Release PCS for a product has changed significantly after original revenue recognition has commenced, the Company will modify remaining estimated deemed service period accordingly and recognize the then-remaining deferred revenue balance over the revised deemed service period.
	The Company has established VSOE of fair value for all professional services and training and for some of its support offerings. The Company's policy for establishing VSOE of fair value consists of evaluating standalone sales, where available, to determine if a substantial portion of the transactions fall within a reasonable range. If a sufficient volume of standalone sales exist and the standalone pricing for a substantial portion of the transactions falls within a reasonable range, management concludes that VSOE of fair value exists.
	In accordance with ASU No. 2009-14, Certain Revenue Arrangements That Include Software Elements, an amendment to ASC Subtopic 985-605 (“ASU No. 2009-14”), the Company excludes from the scope of software revenue recognition requirements its sales of tangible products that contain both software and non-software components that function together to deliver the essential functionality of the tangible products. The Company adopted ASU No. 2009-13 and ASU No. 2009-14 prospectively on January 1, 2011 for new and materially modified arrangements originating after December 31, 2010.
	Prior to our adoption of ASU No. 2009-14, the Company primarily recognized revenues using the revenue recognition criteria of Accounting Standards Codification, or ASC, Subtopic 985-605, Software-Revenue Recognition. As a result of its adoption of ASU No. 2009-14 on January 1, 2011, a majority of the Company’s products are now considered non-software elements under GAAP, which excludes them from the scope of ASC Subtopic 985-605 and includes them within the scope of ASC Topic 605, Revenue Recognition. Because the Company had not been able to establish VSOE of fair value for Implied Maintenance Release PCS, as described further below, substantially all revenue arrangements prior to January 1, 2011 were recognized on a ratable basis over the service period of Implied Maintenance Release PCS. Subsequent to January 1, 2011 and the adoption of ASU No. 2009-14, the Company determines a relative selling price for all elements of the arrangement through the use of BESP, as VSOE and TPE are typically not available, resulting in revenue recognition upon delivery of arrangement consideration attributable to product revenue, provided all other criteria for revenue recognition are met, and revenue recognition of Implied Maintenance Release PCS and other service and support elements over time as services are rendered. As a result of the adoption of these standards, the Company recorded increased revenues and net income of approximately $300 million for the year ended December 31, 2011 (Restated) as compared with results that would have been recorded under the prior accounting standards.
	The timing of revenue recognition of customer arrangements follows a number of different accounting models determined by the characteristics of the arrangement, and that timing can vary significantly from the timing of related cash payments due from customers. One significant factor affecting the timing of revenue recognition is the determination of whether each deliverable in the arrangement is considered to be a software deliverable or a non-software deliverable, as defined under GAAP.
	Revenue Recognition of Non-Software Deliverables
	Revenue from products that are considered non-software deliverables is recognized upon delivery of the product to the customer. Products are considered delivered to the customer once they have been shipped and title and risk of loss have been transferred. For most of the Company’s product sales, these criteria are met at the time the product is shipped. Revenue from support that is considered a non-software deliverable is initially deferred and is recognized ratably over the contractual period of the arrangement, which is generally twelve months. Professional services and training services are typically sold to customers on a time and materials basis. Revenue from professional services and training services that are considered non-software deliverables is recognized for these deliverables as services are provided to the customer. Revenue for Implied Maintenance Release PCS that is considered a non-software deliverable is recognized ratably over the service period of Implied Maintenance Release PCS, which ranges from 1 to 8 years.
	Revenue Recognition of Software Deliverables
	The Company recognizes the following types of elements sold using software revenue recognition guidance: (i) software products and software upgrades, when the software sold in a customer arrangement is more than incidental to the arrangement as a whole and the product does not contain hardware that functions with the software to provide essential functionality, (ii) initial support contracts where the underlying product being supported is considered to be a software deliverable, (iii) support contract renewals, and (iv) professional services and training that relate to deliverables considered to be software deliverables. Because the Company does not have VSOE of the fair value of its software products, it is permitted to account for its typical customer arrangements that include multiple elements using the residual method. Under the residual method, the VSOE of fair value of the undelivered elements (which could include support, professional services or training, or any combination thereof) is deferred and the remaining portion of the total arrangement fee is recognized as revenue for the delivered elements. If evidence of the VSOE of fair value of one or more undelivered elements does not exist, revenues are deferred and recognized when delivery of those elements occurs or when VSOE of fair value can be established. VSOE is typically based on the price charged when the element is sold separately to customers. The Company is unable to use the residual method to recognize revenues for most arrangements that include products that are software deliverables under GAAP since VSOE of fair value does not exist for Implied Maintenance Release PCS elements, which are included in a majority of the Company’s arrangements.
	For software products that include Implied Maintenance Release PCS, an element for which VSOE of fair value does not exist, revenue for the entire arrangement fee, which could include combinations of product, professional services, training and support, is recognized ratably as a group over the longest service period of any deliverable in the arrangement, with recognition commencing on the date delivery has occurred for all deliverables in the arrangement (or begins to occur in the case of professional services, training and support). Standalone sales of support contracts are recognized ratably over the service period of the product being supported.
	From time to time, the Company offers certain customers free upgrades or specified future products or enhancements. When a software deliverable arrangement contains an Implied Maintenance Release PCS deliverable, revenue recognition of the entire arrangement will only commence when any free upgrades or specified future products or enhancements have been delivered, assuming all other products in the arrangement have been delivered and all services, if any, have commenced.
	Other Revenue Recognition Policies
	In a limited number of arrangements, the professional services and training to be delivered are considered essential to the functionality of the Company’s software products. If services sold in an arrangement are deemed to be essential to the functionality of the software products, the arrangement is accounted for using contract accounting. As the Company has concluded that it cannot reliably estimate its contract costs, the Company uses the completed contract method of contract accounting. The completed contract method of accounting defers all revenue and costs until the date that the products have been delivered and professional services, exclusive of post-contract customer support, have been completed. Deferred costs related to fully deferred contracts are recorded as a component of inventories in the consolidated balance sheet, and generally all other costs of sales are recognized when revenue recognition commences.
	The Company records as revenues all amounts billed to customers for shipping and handling costs and records its actual shipping costs as a component of cost of revenues. Reimbursements received from customers for out-of-pocket expenses are recorded as revenues, with related costs recorded as cost of revenues. The Company presents revenues net of any taxes collected from customers and remitted to government authorities.
	In the consolidated statements of operations, the Company classifies revenues as product revenues or services revenues. For multiple-element arrangements that include both product and service elements, including Implied Maintenance Release PCS, the Company evaluates available indicators of fair value and applies its judgment to reasonably classify the arrangement fee between product revenues and services revenues. The amount of multiple-element arrangement fees classified as product and service revenues based on management estimates of fair value when VSOE of fair value for all elements of an arrangement does not exist could differ from amounts classified as product and service revenues if VSOE of fair value for all elements existed.
	Allowance for Sales Returns and Exchanges
	The Company maintains allowances for estimated potential sales returns and exchanges from its customers. The Company records a provision for estimated returns and other allowances as a reduction of revenues in the same period that related revenues are recorded based on historical experience and specific customer analysis. Use of management estimates is required in connection with establishing and maintaining a sales allowance for expected returns and other credits. If actual returns differ from the estimates, additional allowances could be required.
	The following table sets forth the activity in the allowance for sales returns and exchanges for the years ended December 31, 2013, 2012 and 2011 (Restated) (in thousands):
		Year Ended December 31,
		2013				2012			2011 (Restated)

	Allowance for sales returns and exchanges – end of year	$	12,519			$	19,460		$	22,767
	Allowances for Doubtful Accounts
	The Company maintains allowances for estimated losses from bad debt resulting from the inability of its customers to make required payments for products or services. When evaluating the adequacy of the allowances, the Company analyzes accounts receivable balances, historical bad debt experience, customer concentrations, customer credit worthiness and current economic trends. To date, actual bad debts have not differed materially from management’s estimates.

RESTATEMENT OF CONSOLIDATED FINANCIAL STATEMENTS (Policies)	12 Months Ended
	Dec. 31, 2013
Accounting Policies [Abstract]	'
Basis of presentation	'
	Principles of Consolidation
	The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. Intercompany balances and transactions have been eliminated.
	Basis of Presentation
	The Company’s 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 disclosures of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reported periods. Actual results could differ from the Company’s estimates.
Translation of foreign currencies	'
	Translation of Foreign Currencies
	The functional currency of each of the Company’s foreign subsidiaries is the local currency, except for the Irish manufacturing branch whose functional currency is the U.S. dollar due to the extensive interrelationship of the operations of the Irish branch and the U.S. parent and the high volume of intercompany transactions between that branch and the parent. The assets and liabilities of the subsidiaries whose functional currencies are other than the U.S. dollar are translated into U.S. dollars at the current exchange rate in effect at the balance sheet date. Income and expense items for these entities are translated using rates that approximate those in effect during the period. Cumulative translation adjustments are included in accumulated other comprehensive income (loss), which is reflected as a separate component of stockholders’ deficit. The Company does not record tax provisions or benefits for the net changes in the foreign currency translation adjustment as the Company intends to permanently reinvest undistributed earnings in its foreign subsidiaries.
	The U.S. parent company and its Irish manufacturing branch, both of whose functional currency is the U.S. dollar, carry certain monetary assets and liabilities denominated in currencies other than the U.S. dollar. These assets and liabilities typically include cash, accounts receivable and intercompany operating balances denominated in foreign currencies. These assets and liabilities are remeasured into the U.S. dollar at the current exchange rate in effect at the balance sheet date. Foreign currency transaction and remeasurement gains and losses are included within marketing and selling expenses in the results of operations. See Note D for the net foreign exchange gains and losses recorded in the Company’s statements of operations during the years ended December 31, 2013, 2012 and 2011 (Restated) that resulted from the gains and losses on Company’s foreign currency contracts and the revaluation of the related hedged items.
	The U.S. parent company and various other wholly owned subsidiaries have long-term intercompany loan balances denominated in foreign currencies that are remeasured into the U.S. dollar at the current exchange rate in effect at the balance sheet date. Such loan balances are not expected to be settled in the foreseeable future. Any gains and losses relating to these loans are included in the accumulated other comprehensive income (loss), which is reflected as a separate component of stockholders’ deficit.
Cash and cash equivalents	'
	Cash, Cash Equivalents and Marketable Securities
	Cash equivalents consist primarily of commercial paper, money market investments and certificates of deposit. The Company considers all debt instruments purchased with an original maturity of three months or less to be cash equivalents. Marketable securities, have historically consisted of certificates of deposit, commercial paper, asset-backed securities, discount notes, and corporate, municipal, agency and foreign bonds. The Company generally invests in securities that mature within one year from the date of purchase. The Company classifies its cash equivalents and marketable securities as “available for sale” and reports them at fair value, with unrealized gains and losses excluded from earnings and reported as an adjustment to other comprehensive income (loss), which is reflected as a separate component of stockholders’ deficit. Amortization or accretion of premium or discount is included in interest income (expense) in the results of operations. Other than those investments held in the Company’s deferred compensation plan, the Company held no available for sale securities classified as either cash equivalents or marketable securities at December 31, 2013 or 2012.
	Cash equivalents and marketable securities, including money market investments and mutual funds accounted for as trading securities, held in the Company’s deferred compensation plan are reported at fair value using quoted prices with the gains and losses included as other income (expense) in the Company’s statement of operations. Realized gains and losses from the Company’s deferred compensation plans were not material for the years ended December 31, 2013, 2012 and 2011 (Restated).
Concentration of credit risk	'
	Concentration of Credit Risk
	Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents, foreign currency contracts and accounts receivable. The Company may place its excess cash in marketable investment grade securities and uses foreign currency contracts to manage certain of its short-term exposures to fluctuations in foreign currency exchange rates. The Company places its cash and cash equivalents and foreign currency contracts with financial institutions that management believes to be of high credit quality, and, generally, there are no significant concentrations in any one issuer of debt securities. Concentrations of credit risk with respect to trade receivables are limited due to the large number of customers that make up the Company’s customer base and their dispersion across different regions. No individual customer accounted for 10% or more of the Company’s net revenues or net accounts receivable in the periods presented.
Foreign currency risk	'
	Foreign Currency Risk
	The Company has significant international operations and, therefore, the Company’s revenues, earnings, cash flows and financial position are exposed to foreign currency risk from foreign-currency-denominated receivables, payables, sales and expense transactions, and net investments in foreign operations. The Company derives more than half of its revenues from customers outside the United States. This business is, for the most part, transacted through international subsidiaries and generally in the currency of the end-user customers. Therefore, the Company is exposed to the risks that changes in foreign currency could adversely affect its revenues, net income, cash flow and financial position. The Company uses derivatives in the form of foreign currency contracts to manage its short-term exposures to fluctuations in the foreign currency exchange rates that exist as part of its ongoing international business operations. The Company does not enter into any derivative instruments for trading or speculative purposes.
	The Company records all foreign currency contract derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as hedges of the exposure to changes in the fair value of an asset, liability or firm commitment attributable to a particular risk are considered fair value hedges. Derivatives designated and qualifying as hedges of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. Under hedge accounting, the determination of hedge effectiveness is dependent upon whether the gain or loss on the hedging derivative is highly effective in offsetting the gain or loss in the value of the item being hedged.
Inventories	'
	Inventories
	Inventories are stated at the lower of cost (determined on a first-in, first-out basis) or market value. Management regularly reviews inventory quantities on hand and writes down inventory to its realizable value to reflect estimated obsolescence or lack of marketability based on assumptions about future inventory demand and market conditions. Inventory in the digital-media market, including the Company’s inventory, is subject to rapid technological change or obsolescence; therefore, utilization of existing inventory may differ from the Company’s estimates.
Property and equipment	'
	Property and Equipment
	Property and equipment is recorded at cost and depreciated using the straight-line method over the estimated useful life of the asset. The Company typically depreciates its property and equipment using the following minimum and maximum useful lives:
		Depreciable Life (years)
		Minimum	Maximum
	Computer and video equipment and software	2	5
	Manufacturing tooling and testbeds	3	5
	Office equipment	3	5
	Furniture, fixtures and other	3	8
	Leasehold improvements are amortized over the shorter of the useful life of the improvement or the remaining term of the lease. Expenditures for maintenance and repairs are expensed as incurred. Upon retirement or other disposition of assets, the cost and related accumulated depreciation are eliminated from the accounts and the resulting gain or loss is reflected in other income (expense) in the results of operations.
Assets held-for-sale and gain on sales of assets	'
	Discontinued Operations
	The Company classifies the assets and liabilities of a business as held-for-sale when management approves and commits to a formal plan of sale and it is probable that the sale will be completed. The carrying value of the net assets of the business held-for-sale are then recorded at the lower of their carrying value or fair market value, less costs to sell. As discussed in Note I, the Company completed the sales of the consumer audio and consumer video product lines in the third quarter of 2012. The operations of divested businesses have been reflected as discontinued operations for all periods presented in these consolidated financial statements.
Long-lived assets	'
	Long-Lived Assets
	The Company periodically evaluates its long-lived assets for events and circumstances that indicate a potential impairment. A long-lived asset is assessed for impairment when the undiscounted expected future cash flows derived from that asset are less than its carrying value. The cash flows used for this analysis take into consideration a number of factors including past operating results, budgets and economic projections, market trends and product development cycles. The amount of any impairment would be equal to the difference between the estimated fair value of the asset, based on a discounted cash flow analysis, and its carrying value.
Advertising expenses	'
	Advertising Expenses
	All advertising costs are expensed as incurred and are classified as marketing and selling expenses. Advertising expenses during 2013, 2012 and 2011 (Restated) were $1.8 million, $3.1 million and $3.8 million, respectively.
Research and development costs	'
	Research and Development Costs
	Research and development costs are expensed as incurred, except for costs that qualify for capitalization. Development costs for software to be sold that are incurred subsequent to the establishment of technological feasibility, but prior to the general release of the product, are capitalized. Upon general release, these costs are amortized using the straight-line method over the expected life of the related products, generally 12 to 36 months. The straight-line method generally results in approximately the same amount of expense as that calculated using the ratio that current period gross product revenues bear to total anticipated gross product revenues. The Company periodically evaluates the assets, considering a number of business and economic factors, to determine if an impairment exits.
Income taxes	'
	Income Taxes
	The Company accounts for income taxes using an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Company’s financial statements or tax returns. The Company records deferred tax assets and liabilities based on the net tax effects of tax credits, operating loss carryforwards and temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes compared to the amounts used for income tax purposes. Deferred tax assets are regularly reviewed for recoverability with consideration for such factors as historical losses, projected future taxable income and the expected timing of the reversals of existing temporary differences. The Company is required to record a valuation allowance when it is more likely than not that some portion or all of the deferred tax assets will not be realized. Based on the magnitude of the Company’s deferred tax assets at December 31, 2013 and the historical U.S. losses, the Company has determined that the uncertainty regarding the realization of these assets is sufficient to warrant the need for a full valuation allowance against its U.S. net deferred tax assets. The Company has also determined that a valuation allowance is warranted on a portion of its foreign deferred tax assets.
Computation of net income (loss) per common share	'
	Computation of Net Income Per Share
	Net income per share is presented for both basic earnings per share (“Basic EPS”) and diluted earnings per share (“Diluted EPS”). Basic EPS is based on the weighted-average number of common shares outstanding during the period, excluding non-vested restricted stock held by employees. Diluted EPS is based on the weighted-average number of common and potential common shares outstanding during the period. Potential common shares result from the assumed exercise of outstanding stock options and non-vested restricted stock and restricted stock units, the proceeds and remaining unrecorded compensation expense of which are then assumed to have been used to repurchase outstanding common stock using the treasury stock method. For periods when the Company reports a loss, all potential common stock is considered anti-dilutive. For periods when the Company reports net income, potential common shares with combined purchase prices and unamortized compensation costs in excess of the Company’s average common stock fair value for the related period or that are contingently issuable are considered anti-dilutive. The contingently issuable potential common shares result from certain stock options and restricted stock units granted to the Company’s executive officers that vest based on performance conditions, market conditions, or a combination of performance or market conditions (see Notes C and M).
Accounting for stock-based compensation	'
	Accounting for Stock-Based Compensation
	The Company’s stock-based employee compensation plans allow the Company to grant stock awards, options, or other equity-based instruments, or a combination thereof, as part of its overall compensation strategy. For stock-based awards granted, the Company records stock-based compensation cost based on the grant date fair value over the requisite service periods for the individual awards, which generally equal the vesting periods. The vesting of stock-based award grants may be based on time, performance conditions, market conditions, or a combination of performance or market conditions.

Based on the Company’s policies for the calculation and payment of severance benefits, the Company accounts for employee-related restructuring charges as an ongoing benefit arrangement in accordance with ASC Topic 712, Compensation - Nonretirement Postemployment Benefits. Restructuring charges and accruals require significant estimates and assumptions, including sub-lease income assumptions. These estimates and assumptions are monitored on at least a quarterly basis for changes in circumstances and any corresponding adjustments to the accrual are recorded in the Company’s statement of operations in the period when such changes are known.

The audio assets were sold to Numark Industries, L.P. (“Numark”) for $11.8 million. Proceeds of $10.9 million were received from Numark in 2012, with the remaining proceeds held in escrow until a final release date that occurred in March 2014. The video assets were sold to Corel Corporation (“Corel”) for $3.0 million. Proceeds of $2.4 million were received from Corel in 2012, with the remaining proceeds held in escrow until a final release date that occurred in January 2014. There was no income tax provision related to the discontinued operations in any period presented.
	The divestiture of these consumer product lines was intended to:
	•	allow the Company to focus on the Broadcast and Media market and the Video and Audio Post and Professional market;
	•	reduce complexity from the Company's operations to improve operational efficiencies; and
	•	allow the Company to change its cost structure, by moving away from lower growth, lower margin sectors to drive improved financial performance.
