Organization, Consolidation and Presentation of Financial Statements [Abstract]	'
FINANCIAL INFORMATION	'
	FINANCIAL INFORMATION
	The accompanying condensed consolidated financial statements include the accounts of Avid Technology, Inc. and its wholly owned subsidiaries (collectively, “Avid” or the “Company”). These financial statements are unaudited. However, in the opinion of management, the condensed consolidated financial statements reflect all normal and recurring adjustments necessary for their fair statement. Interim results are not necessarily indicative of results expected for any other interim period or a full year. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions for Form 10-Q and, therefore, do not include all information and footnotes necessary for a complete presentation of operations, comprehensive income, financial position and cash flows of the Company in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The accompanying condensed consolidated balance sheet as of December 31, 2012 was derived from the Company’s audited consolidated financial statements but does not include all disclosures required by U.S. GAAP for annual financial statements. The Company’s audited consolidated financial statements as of and for the year ended December 31, 2012 are included in its Annual Report on Form 10-K for the year ended December 31, 2013, which includes all information and footnotes necessary for such presentation. The financial statements contained in this Form 10-Q should be read in conjunction with the audited consolidated financial statements in the Form 10-K.
	The Company’s preparation of condensed consolidated financial statements in conformity with U.S. GAAP 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 condensed consolidated financial statements and the reported amounts of revenues and expenses during the reported periods. Actual results could differ from the Company’s estimates.
	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. 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.
	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, (iii) and added certain 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.
	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 financial statements and except for the subsequent events disclosed above and in Note 10, no other subsequent events required recognition or disclosure in these financial statements.
	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 [Text Block]	'
	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 more fully below, the Company has restated its financial statements for the three and nine months ended September 30, 2012.
	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 to the Consolidated Financial Statements in Item 8 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2013, 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 after several years. The errors in the timing of revenue recognition have been corrected in the restated condensed 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 stock-based compensation and income taxes, which have also been restated in the restated condensed consolidated financial statements.
	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 identified an error in the facility restructuring charge of $4.3 million recorded in the three and nine months ended September 30, 2012, where the Company failed to reflect a required assumption that an expected subtenant would absorb common area maintenance charges. The Company also identified an overstatement of severance costs accruals primarily due to an incorrect estimate originally recorded in the three months ended June 30, 2012. The overstatement totaled $1.1 million in the nine months ended September 30, 2012.
	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 reclassifications between cost of sales and operating expenses, as well as errors in inventories, stock-based compensations and accrued liabilities. The provision for income taxes has been adjusted to reflect the changes in quarterly income before taxes.
	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 7, the disposition of the consumer business qualified for presentation as discontinued operations; therefore, these financial statements have been retrospectively adjusted for all periods presented to report the consumer business as a discontinued operation. In the previously issued financial statements, the sale of the consumer business was incorrectly included in continuing operations.
	Adjustments to Condensed Consolidated Statement of Operations
	The following tables present the impact of the financial statement adjustments on the Company’s previously reported condensed consolidated statements of operations for the three and nine months ended September 30, 2012 (in thousands except per share data):

	NET INCOME PER SHARE
	Net income per common share is presented for both basic income per share (“Basic EPS”) and diluted income per share (“Diluted EPS”). Basic EPS is based on the weighted-average number of common shares outstanding during the period. Diluted EPS is based on the weighted-average number of common shares and potential common shares outstanding during the period.
	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 CONTRACTS
	As a hedge against the foreign exchange exposure of certain forecasted receivables, payables and cash balances of 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. At September 30, 2013 and December 31, 2012, the Company had foreign currency forward contracts outstanding with aggregate notional values of $28.6 million and $23.6 million, respectively, as hedges against such forecasted foreign-currency-denominated receivables, payables and cash balances. These forward contracts typically mature within 30 days of execution.
	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 September 30, 2013 and December 31, 2012, the Company had such foreign currency contracts with aggregate notional values of $3.7 million and $5.3 million, respectively. The fair values of these foreign currency contracts are also recorded as gains or losses in the Company’s statement of operations in the period of change.

	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 September 30, 2013 and December 31, 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 September 30, 2013 and December 31, 2012 (in thousands):
				Fair Value Measurements at Reporting Date Using
		September 30,		Quoted Prices in		Significant		Significant

	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 4 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.

	DISCONTINUED OPERATIONS
	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 the three months ended September 30, 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 during 2012, with the remaining proceeds held in escrow until a final release date 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 the third quarter of 2012, with the remaining proceeds held in escrow until a final release date 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.

	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 September 30, 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 September 30, 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 September 30, 2013 and 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 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 September 30, 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 September 30, 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 has letters of credit totaling approximately $2.6 million that support its ongoing operations. These letters of credit have various terms and expire during 2013 and 2014. Some of the letters of credit may automatically renew based on the terms of the underlying agreements.
	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 nine months ended September 30, 2013 and 2012 (in thousands):

	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 $1.4 million during the second and third quarters of 2013.
	2012 Restructuring Plan
	In June 2012, the Company committed to a series of strategic actions (the “2012 Plan”) to focus on the 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 and the abandonment of one of the Company’s facilities in Burlington, Massachusetts and 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. The Company substantially completed all actions under the 2012 Plan prior to December 31, 2012.
	During the first nine months of 2013, the Company recorded revisions totaling $1.0 million, primarily resulting from sublease assumption changes and other lease-related fees.
	Prior Year Restructuring Plans
	During the first nine months of 2012, the Company recorded revisions totaling $3 million, primarily resulting from sublease

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, (iii) and added certain 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.
	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 financial statements and except for the subsequent events disclosed above and in Note 10, no other subsequent events required recognition or disclosure in these financial statements.
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.
