Accounting Policies [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	SIGNIFICANT ACCOUNTING POLICIES Description of Business Immersion Corporation (the “Company”) was incorporated in 1993 in California and reincorporated in Delaware in 1999. The Company focuses on the creation, design, development, and licensing of innovative haptic technologies that allow people to use their sense of touch more fully as they engage with cutting-edge products and experience the digital world around them. The Company has adopted a “hybrid” business model, under which it provides advanced tactile software, related tools, and technical assistance to certain customers; and offers licenses to the Company's patented intellectual property (“IP”) to other customers. Principles of Consolidation and Basis of Presentation The condensed consolidated financial statements include the accounts of Immersion Corporation and its wholly-owned subsidiaries: Immersion Canada Corporation; Immersion International, LLC; Immersion Medical, Inc.; Immersion Japan K.K.; Immersion Ltd.; Immersion Software Ireland Ltd.; Haptify, Inc.; Immersion (Shanghai) Science & Technology Company, Ltd.; and Immersion Technology International Ltd. All intercompany accounts, transactions, and balances have been eliminated in consolidation. The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions for Form 10-Q and Article 10 of Regulation S-X and, therefore, do not include all information and footnotes necessary for a complete presentation of the financial position, results of operations, and cash flows, in conformity with GAAP. These condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements included in the Company’s Annual Report on Form 10-K, for the fiscal year ended December 31, 2015 . In the opinion of management, all adjustments consisting of only normal and recurring items necessary for the fair presentation of the financial position and results of operations for the interim periods presented have been included. The results of operations for the three months ended March 31, 2016 are not necessarily indicative of the results to be expected for the full year. Segment Information The Company develops, licenses, and supports a wide range of software and IP that more fully engage users’ sense of touch when operating digital devices. The Company focuses on the following target application areas: mobility and consumer electronics, automotive, gaming, commercial and industrial, and medical. The Company’s chief operating decision maker (“CODM”) is the Chief Executive Officer. The CODM allocates resources to and assesses the performance of the Company using information about its financial results as one operating and reporting segment. Revenue Recognition The Company recognizes revenues in accordance with applicable accounting standards, including ASC 605-10-S99, “Revenue Recognition” (“ASC 605-10-S99”); ASC 605-25, “Multiple Element Arrangements” (“ASC 605-25”); and ASC 985-605, “Software-Revenue Recognition” (“ASC 985-605”). The Company derives its revenues from two principal sources: royalty and license fees, and development contract and service fees. As described below, management judgments, assumptions, and estimates must be made and used in connection with the revenue recognized in any accounting period. Material differences may result in the amount and timing of revenue for any period based on the judgments and estimates made by management. Specifically, in connection with each transaction, the Company must evaluate whether: (i) persuasive evidence of an arrangement exists, (ii) delivery has occurred, (iii) the fee is fixed or determinable, and (iv) collectibility is probable. The Company applies these criteria as discussed below. • Persuasive evidence of an arrangement exists . For a license arrangement, the Company requires a written contract, signed by both the customer and the Company. • Delivery has occurred . The Company delivers software to customers physically and also delivers software electronically. For electronic deliveries, delivery occurs when the Company provides the customer access codes or “keys” that allow the customer to take immediate possession of the software. • The fee is fixed or determinable . The Company’s arrangement fee is based on the use of standard payment terms, which are those that are generally offered to the majority of customers. For transactions involving extended payment terms, the Company deems these fees not to be fixed or determinable for revenue recognition purposes and revenue is deferred until the fees become due and payable. • Collectibility is probable. To recognize revenue, the Company must judge collectibility of fees, which is done on a customer-by-customer basis pursuant to the Company’s credit review policy. The Company typically sells to customers with whom there is a history of successful collection. For new customers, the Company evaluates the customer’s financial condition and ability to pay. If it is determined that collectibility is not probable based upon the credit review process or the customer’s payment history, revenue is recognized when payment is received. Royalty and license revenue — The Company licenses its patents and software to customers in a variety of industries such as mobility, gaming, automotive, and medical devices. Certain of these are variable fee arrangements where the royalties earned by the Company are based on unit or sales volumes of the respective licensees. The Company also enters into fixed license fee arrangements. The terms of the royalty agreements generally require licensees to give notification of royalties due to the Company within 30 – 45 days of the end of the quarter during which their related sales occur. As the Company is unable to reliably estimate the licensees’ sales in any given quarter to determine the royalties due to it, the Company recognizes royalty revenues based on royalties reported by licensees and when all revenue recognition criteria are met. Certain royalties are based upon customer shipments or revenues and could be subject to change and may result in out of period adjustments. The Company recognizes fixed license fee revenue for licenses when earned under the terms of the agreements, which is generally recognized on a straight-line basis over the expected term of the license. Development, services, and other revenue — Development, services, and other revenue are composed of engineering services (engineering services and/or development contracts), and in limited cases, post contract customer support (“PCS”). Engineering services revenues are recognized under the proportional performance accounting method based on physical completion of the work to be performed or completed performance method. A provision for losses on contracts is made, if necessary, in the period in which the loss becomes probable and can be reasonably estimated. Revisions in estimates are reflected in the period in which the conditions become known. To date, such losses have not been significant. Revenue from PCS is typically recognized over the period of the ongoing obligation, which is generally consistent with the contractual term. Multiple element arrangements — The Company enters into multiple element arrangements in which customers purchase time-based non-exclusive licenses that cannot be resold to others, which include a combination of software and/or IP licenses, engineering services, and in limited cases PCS. For arrangements that are software based and include software and engineering services, the services are generally not essential to the functionality of the software, and customers may purchase engineering services to facilitate the adoption of the Company’s technology, but they may also decide to use their own resources or appoint other engineering service organizations to perform these services. For arrangements that are in substance subscription arrangements, the entire arrangement fee is recognized ratably over the contract term, subject to any limitations related to extended payment terms. For arrangements involving upfront fees for services and royalties earned by the Company based on unit or sales volumes of the respective licensees, and the services are performed ratably over the arrangement or are front-end loaded, the upfront fees are recognized ratably over the contract term and royalties based on unit or sales volume are recognized when they become fixed and determinable. As the Company is unable to reliably estimate the licensees’ sales in any given quarter to determine the royalties due to it, the Company recognizes per unit or sales volume driven royalty revenues based on royalties reported by licensees and when all revenue recognition criteria are met. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09 “Revenue from Contracts with Customers: Topic 606” (“ASU 2014-09”) which will supersede the current revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Further, the guidance requires improved disclosures to help users of financial statements better understand the nature, amount, timing, and uncertainty of revenue that is recognized. In August 2015, the FASB issued ASU No. 2015-14 “Revenue from Contracts with Customers: Deferral of the Effective Date”, which deferred the effective date of ASU 2014-09 for periods beginning after December 15, 2016 to December 15, 2017, with early adoption permitted but not earlier than the original effective date. Accordingly, ASU 2014-09 is effective for the Company and is expected to be adopted in the first quarter of fiscal 2018. The standard permits companies to either apply the requirements retrospectively to all prior periods presented, or apply the requirements in the year of adoption through a cumulative adjustment, and the Company is in the process of determining the method of adoption and evaluating the impact on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02 “Leases: Topic 842” (“ASU 2016-02”) which supersedes the existing guidance for lease accounting in Topic 840, Leases. The FASB issued the standard to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. ASU 2016-02 requires lessees to recognize a lease liability and a right-of-use asset for all leases. Lessor accounting remains largely unchanged. The amendments of this ASU are effective for periods beginning after December 15, 2018, with early adoption permitted. An entity will be required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The Company is currently in the process of evaluating the impact of this standard on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-09 “Compensation - Stock Compensation: Topic 718” (“ASU 2016-09”) which simplifies several aspects of the accounting for share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities, and classification in the statement of cash flows. The standard is effective for periods beginning after December 15, 2016, with early adoption permitted. The Company is currently in the process of evaluating the impact of this standard on its consolidated financial statements.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS Cash Equivalents and Short-term Investments The financial instruments of the Company measured at fair value on a recurring basis are cash equivalents and short-term investments. The Company’s fixed income available-for-sale securities consist of high quality, investment grade securities. The Company values these securities based on pricing from pricing vendors, who may use quoted prices in active markets for identical assets (Level 1) or inputs other than quoted prices that are observable either directly or indirectly (Level 2) in determining fair value. The types of instruments valued based on quoted market prices in active markets include money market securities. Such instruments are generally classified within Level 1 of the fair value hierarchy. The types of instruments valued based on quoted prices in markets that are less active, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency are generally classified within Level 2 of the fair value hierarchy and include U.S. treasury securities. The types of instruments valued based on unobservable inputs which reflect the reporting entity’s own assumptions or data that market participants would use in valuing an instrument are generally classified within Level 3 of the fair value hierarchy. The Company had no Level 3 instruments as of March 31, 2016 and December 31, 2015 . Financial instruments measured at fair value on a recurring basis as of March 31, 2016 and December 31, 2015 are classified based on the valuation technique in the table below: March 31, 2016 Fair value measurements using Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total (In thousands) Assets: U.S. Treasury securities $ — $ 39,927 $ — $ 39,927 Money market accounts 6,041 — — 6,041 Total assets at fair value $ 6,041 $ 39,927 $ — $ 45,968 The above table excludes $14.8 million of cash held in banks.

STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATION Stock Options and Awards The Company’s equity incentive program is a long-term retention program that is intended to attract, retain, and provide incentives for talented employees, consultants, officers, and directors and to align stockholder and employee interests. The Company may grant time based options, market condition based options, stock appreciation rights, restricted stock, restricted stock units (“RSUs”), performance shares, performance units, and other stock-based or cash-based awards to employees, officers, directors, and consultants. Under this program, stock options may be granted at prices not less than the fair market value on the date of grant for stock options. These options generally vest over four years and expire from seven to ten years from the date of grant. In addition to time based vesting, market condition based options are subject to a market condition: the closing price of the Company stock must exceed a certain level for a number of trading days within a specified timeframe or the options will be cancelled before the expiration of the options. Restricted stock generally vests over one year. RSUs generally vest over three years. Awards granted other than an option or stock appreciation right reduce the common stock shares available for grant under the program by 1.75 shares for each share issued. March 31, 2016 Common stock shares available for grant 729,149 Standard and market condition stock options outstanding 3,681,244 Restricted stock awards outstanding 21,356 Restricted stock units outstanding 527,883 Employee Stock Purchase Plan The Company has an Employee Stock Purchase Plan (“ESPP”). Under the ESPP, eligible employees may purchase common stock through payroll deductions at a purchase price of 85% of the lower of the fair market value of the Company’s stock at the beginning of the offering period or the purchase date. Participants may not purchase more than 2,000 shares in a six -month offering period or purchase stock having a value greater than $25,000 in any calendar year as measured at the beginning of the offering period. A total of 1,000,000 shares of common stock have been reserved for issuance under the ESPP. As of March 31, 2016 , 621,269 shares had been purchased since the inception of the ESPP in 1999. Under ASC 718-10, the ESPP is considered a compensatory plan and the Company is required to recognize compensation cost related to the fair value of the award purchased under the ESPP. Shares purchased under the ESPP for the three months ended March 31, 2016 are listed below. Shares purchased under the ESPP for the three months ended March 31, 2015 are 23,713 .

In addition, on October 22, 2014, the Board authorized another $30.0 million under the share repurchase program. The Company may repurchase its stock for cash in the open market in accordance with applicable securities laws. The timing of and amount of any stock repurchase will depend on share price, corporate and regulatory requirements, economic and market conditions, and other factors. The stock repurchase authorization has no expiration date, does not require the Company to repurchase a specific number of shares, and may be modified, suspended, or discontinued at any time. There were no stock repurchases during the three months ended March 31, 2016 and 2015 . As of March 31, 2016 , the program remains available with approximately $34.4 million that may yet be purchased under the Stock Repurchase Program.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES Income tax provisions consisted of the following: Three Months Ended 2016 2015 (In thousands) Loss before benefit for income taxes $ (4,396 ) $ (95 ) Benefit for income taxes 1,701 36 Effective tax rate 38.7 % 37.9 % The benefit for income tax for the three months ended March 31, 2016 and 2015 resulted primarily from the Company’s federal and foreign tax recognized at statutory rates, adjusted for the tax impact of nondeductible permanent items including stock-based compensation and foreign withholding taxes. The benefit for income tax for the three months ended March 31, 2016 also includes non-cash tax expense on intercompany profit that resulted from the sale of certain IP rights to one of the Company's foreign subsidiaries as part of the Company's reorganization of its international operations during the second half of 2015. Discrete items recognized for the three months ended March 31, 2016 include a tax refund related to the settlement with a taxing authority and the release of certain reserves and related accrued interest. On July 27, 2015, a U.S. Tax Court opinion (Altera Corporation et. al v. Commissioner) concerning the treatment of stock-based compensation expense in an intercompany cost sharing arrangement was issued. In its opinion, the U.S. Tax Court accepted Altera's position of excluding stock-based compensation from its intercompany cost sharing arrangement. On February 19, 2016, the IRS appealed the ruling to the United States Court of Appeals for the Ninth Circuit. Although the IRS has appealed the decision, based on the findings of the U.S. Tax Court, the Company has concluded that it is more likely than not that the decision will be upheld and accordingly has excluded stock-based compensation from intercompany charges during the period. The Company will continue to monitor ongoing developments and potential impacts to its condensed consolidated financial statements. As of March 31, 2016 , the Company had unrecognized tax benefits under ASC 740 “Income Taxes”, of approximately $6.2 million and there was no applicable interest. The total amount of unrecognized tax benefits that would affect the Company’s effective tax rate, if recognized, was $2.4 million . The Company released reserves totaling $310,000 including interest and recorded a tax benefit due to the receipt of a tax refund related to the settlement with a taxing authority as noted above. The Company’s policy is to account for interest and penalties related to uncertain tax positions as a component of income tax provision. We do not expect to have any significant changes to unrecognized tax benefits during the next twelve months. Net deferred income taxes were $26.3 million as of March 31, 2016 , consisting primarily of federal net operating loss carryforwards and timing differences between book and tax. Because the Company had net operating loss and credit carryforwards, there are open statutes of limitations in which federal, state, and foreign taxing authorities may examine the Company’s tax returns for all years from 1998 through the current period. The Company maintains a valuation allowance of $8.2 million against certain of its deferred tax assets, including federal, state, and certain foreign deferred tax assets. The Company has determined there is not sufficient evidence to support the release of the valuation allowance against these federal, state and foreign deferred tax assets.

Earnings Per Share [Abstract]
NET LOSS PER SHARE	NET LOSS PER SHARE Basic and diluted net loss per share is computed using the weighted average number of common shares outstanding for the period, excluding unvested restricted stock and RSUs. The following is a reconciliation of the numerators and denominators used in computing basic and diluted net loss per share: Three Months Ended March 31, 2016 2015 (in thousands except per share amounts) Numerator: Net loss $ (2,695 ) $ (59 ) Denominator: Shares used in computation of basic and diluted net loss per share (weighted average common shares outstanding) 28,493 27,818 Basic and diluted net loss per share $ (0.09 ) $ 0.00 The Company includes the underlying market condition stock options in the calculation of diluted earnings per share if the performance condition has been satisfied as of the end of the reporting period and excludes such options if the performance condition has not been met. As of March 31, 2016 and 2015 , the Company had securities outstanding that could potentially dilute basic earnings per share in the future, but these were excluded from the computation of diluted net loss per share for the three months ended March 31, 2016 and 2015 , since their effect would have been anti-dilutive. These outstanding securities consisted of the following: March 31, 2016 2015 Outstanding stock options 3,681,244 3,875,153 Unvested RSUs 527,883 565,148

Commitments and Contingencies Disclosure [Abstract]
CONTINGENCIES	CONTINGENCIES From time to time, the Company receives claims from third parties asserting that the Company’s technologies, or those of its licensees, infringe on the other parties’ IP rights. Management believes that these claims are without merit. Additionally, periodically, the Company is involved in routine legal matters and contractual disputes incidental to its normal operations. In management’s opinion, the resolution of such matters will not have a material adverse effect on the Company’s condensed consolidated financial condition, results of operations, or liquidity. In the normal course of business, the Company provides indemnification of varying scope to customers against claims of IP infringement made by third parties arising from the use of the Company’s IP, technology, or products. Historically, costs related to these guarantees have not been significant, and the Company is unable to estimate the maximum potential impact of these guarantees on its future results of operations.

SIGNIFICANT ACCOUNTING POLICIES (Policies)	3 Months Ended
	Mar. 31, 2016
Accounting Policies [Abstract]
Description of Business	Immersion Corporation (the “Company”) was incorporated in 1993 in California and reincorporated in Delaware in 1999. The Company focuses on the creation, design, development, and licensing of innovative haptic technologies that allow people to use their sense of touch more fully as they engage with cutting-edge products and experience the digital world around them. The Company has adopted a “hybrid” business model, under which it provides advanced tactile software, related tools, and technical assistance to certain customers; and offers licenses to the Company's patented intellectual property (“IP”) to other customers.
Principles of Consolidation and Basis of Presentation	The condensed consolidated financial statements include the accounts of Immersion Corporation and its wholly-owned subsidiaries: Immersion Canada Corporation; Immersion International, LLC; Immersion Medical, Inc.; Immersion Japan K.K.; Immersion Ltd.; Immersion Software Ireland Ltd.; Haptify, Inc.; Immersion (Shanghai) Science & Technology Company, Ltd.; and Immersion Technology International Ltd. All intercompany accounts, transactions, and balances have been eliminated in consolidation. The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions for Form 10-Q and Article 10 of Regulation S-X and, therefore, do not include all information and footnotes necessary for a complete presentation of the financial position, results of operations, and cash flows, in conformity with GAAP. These condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements included in the Company’s Annual Report on Form 10-K, for the fiscal year ended December 31, 2015 . In the opinion of management, all adjustments consisting of only normal and recurring items necessary for the fair presentation of the financial position and results of operations for the interim periods presented have been included. The results of operations for the three months ended March 31, 2016 are not necessarily indicative of the results to be expected for the full year.
Segment Information	The Company develops, licenses, and supports a wide range of software and IP that more fully engage users’ sense of touch when operating digital devices. The Company focuses on the following target application areas: mobility and consumer electronics, automotive, gaming, commercial and industrial, and medical. The Company’s chief operating decision maker (“CODM”) is the Chief Executive Officer. The CODM allocates resources to and assesses the performance of the Company using information about its financial results as one operating and reporting segment.
Revenue Recognition	The Company recognizes revenues in accordance with applicable accounting standards, including ASC 605-10-S99, “Revenue Recognition” (“ASC 605-10-S99”); ASC 605-25, “Multiple Element Arrangements” (“ASC 605-25”); and ASC 985-605, “Software-Revenue Recognition” (“ASC 985-605”). The Company derives its revenues from two principal sources: royalty and license fees, and development contract and service fees. As described below, management judgments, assumptions, and estimates must be made and used in connection with the revenue recognized in any accounting period. Material differences may result in the amount and timing of revenue for any period based on the judgments and estimates made by management. Specifically, in connection with each transaction, the Company must evaluate whether: (i) persuasive evidence of an arrangement exists, (ii) delivery has occurred, (iii) the fee is fixed or determinable, and (iv) collectibility is probable. The Company applies these criteria as discussed below. • Persuasive evidence of an arrangement exists . For a license arrangement, the Company requires a written contract, signed by both the customer and the Company. • Delivery has occurred . The Company delivers software to customers physically and also delivers software electronically. For electronic deliveries, delivery occurs when the Company provides the customer access codes or “keys” that allow the customer to take immediate possession of the software. • The fee is fixed or determinable . The Company’s arrangement fee is based on the use of standard payment terms, which are those that are generally offered to the majority of customers. For transactions involving extended payment terms, the Company deems these fees not to be fixed or determinable for revenue recognition purposes and revenue is deferred until the fees become due and payable. • Collectibility is probable. To recognize revenue, the Company must judge collectibility of fees, which is done on a customer-by-customer basis pursuant to the Company’s credit review policy. The Company typically sells to customers with whom there is a history of successful collection. For new customers, the Company evaluates the customer’s financial condition and ability to pay. If it is determined that collectibility is not probable based upon the credit review process or the customer’s payment history, revenue is recognized when payment is received. Royalty and license revenue — The Company licenses its patents and software to customers in a variety of industries such as mobility, gaming, automotive, and medical devices. Certain of these are variable fee arrangements where the royalties earned by the Company are based on unit or sales volumes of the respective licensees. The Company also enters into fixed license fee arrangements. The terms of the royalty agreements generally require licensees to give notification of royalties due to the Company within 30 – 45 days of the end of the quarter during which their related sales occur. As the Company is unable to reliably estimate the licensees’ sales in any given quarter to determine the royalties due to it, the Company recognizes royalty revenues based on royalties reported by licensees and when all revenue recognition criteria are met. Certain royalties are based upon customer shipments or revenues and could be subject to change and may result in out of period adjustments. The Company recognizes fixed license fee revenue for licenses when earned under the terms of the agreements, which is generally recognized on a straight-line basis over the expected term of the license. Development, services, and other revenue — Development, services, and other revenue are composed of engineering services (engineering services and/or development contracts), and in limited cases, post contract customer support (“PCS”). Engineering services revenues are recognized under the proportional performance accounting method based on physical completion of the work to be performed or completed performance method. A provision for losses on contracts is made, if necessary, in the period in which the loss becomes probable and can be reasonably estimated. Revisions in estimates are reflected in the period in which the conditions become known. To date, such losses have not been significant. Revenue from PCS is typically recognized over the period of the ongoing obligation, which is generally consistent with the contractual term. Multiple element arrangements — The Company enters into multiple element arrangements in which customers purchase time-based non-exclusive licenses that cannot be resold to others, which include a combination of software and/or IP licenses, engineering services, and in limited cases PCS. For arrangements that are software based and include software and engineering services, the services are generally not essential to the functionality of the software, and customers may purchase engineering services to facilitate the adoption of the Company’s technology, but they may also decide to use their own resources or appoint other engineering service organizations to perform these services. For arrangements that are in substance subscription arrangements, the entire arrangement fee is recognized ratably over the contract term, subject to any limitations related to extended payment terms. For arrangements involving upfront fees for services and royalties earned by the Company based on unit or sales volumes of the respective licensees, and the services are performed ratably over the arrangement or are front-end loaded, the upfront fees are recognized ratably over the contract term and royalties based on unit or sales volume are recognized when they become fixed and determinable. As the Company is unable to reliably estimate the licensees’ sales in any given quarter to determine the royalties due to it, the Company recognizes per unit or sales volume driven royalty revenues based on royalties reported by licensees and when all revenue recognition criteria are met.
Recent Accounting Pronouncements	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09 “Revenue from Contracts with Customers: Topic 606” (“ASU 2014-09”) which will supersede the current revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Further, the guidance requires improved disclosures to help users of financial statements better understand the nature, amount, timing, and uncertainty of revenue that is recognized. In August 2015, the FASB issued ASU No. 2015-14 “Revenue from Contracts with Customers: Deferral of the Effective Date”, which deferred the effective date of ASU 2014-09 for periods beginning after December 15, 2016 to December 15, 2017, with early adoption permitted but not earlier than the original effective date. Accordingly, ASU 2014-09 is effective for the Company and is expected to be adopted in the first quarter of fiscal 2018. The standard permits companies to either apply the requirements retrospectively to all prior periods presented, or apply the requirements in the year of adoption through a cumulative adjustment, and the Company is in the process of determining the method of adoption and evaluating the impact on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02 “Leases: Topic 842” (“ASU 2016-02”) which supersedes the existing guidance for lease accounting in Topic 840, Leases. The FASB issued the standard to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. ASU 2016-02 requires lessees to recognize a lease liability and a right-of-use asset for all leases. Lessor accounting remains largely unchanged. The amendments of this ASU are effective for periods beginning after December 15, 2018, with early adoption permitted. An entity will be required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The Company is currently in the process of evaluating the impact of this standard on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-09 “Compensation - Stock Compensation: Topic 718” (“ASU 2016-09”) which simplifies several aspects of the accounting for share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities, and classification in the statement of cash flows. The standard is effective for periods beginning after December 15, 2016, with early adoption permitted. The Company is currently in the process of evaluating the impact of this standard on its consolidated financial statements.
