Accounting Policies [Abstract]
BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES	BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES Take-Two Interactive Software, Inc. (the "Company," "we," "us," or similar pronouns) was incorporated in the state of Delaware in 1993. We are a leading developer, publisher and marketer of interactive entertainment for consumers around the globe. We develop and publish products principally through our two wholly-owned labels Rockstar Games and 2K. Our products are designed for console systems and personal computers, including smart phones and tablets, and are delivered through physical retail, digital download, online platforms and cloud streaming services. Basis of Presentation The accompanying Condensed Consolidated Financial Statements are unaudited and include the accounts of the Company and its wholly-owned subsidiaries and, in the opinion of management, reflect all normal and recurring adjustments necessary for the fair presentation of our financial position, results of operations and cash flows. Interim results may not be indicative of the results that may be expected for the full fiscal year. All inter-company accounts and transactions have been eliminated in consolidation. The preparation of these Condensed Consolidated Financial Statements in accordance with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in these Condensed Consolidated Financial Statements and accompanying notes. As permitted under generally accepted accounting principles in the United States, interim accounting for certain expenses, including income taxes, are based on full year assumptions when appropriate. Actual results could differ materially from those estimates. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been omitted pursuant to the rules and regulations of the Securities and Exchange Commission, although we believe that the disclosures are adequate to make the information presented not misleading. These Condensed Consolidated Financial Statements and accompanying notes should be read in conjunction with our annual consolidated financial statements and the notes thereto, included in our Annual Report on Form 10-K for the fiscal year ended March 31, 2017 . Certain immaterial reclassifications have been made to prior period amounts to conform to the current period presentation. Revenue Recognition As part of our on-going assessment of estimated service periods, in June 2017, we extended Grand Theft Auto V's estimated service period from 41 through 50 months, or through December 2018. We expect this change in estimated service period to have a material impact on our Consolidated Financial Statements for fiscal 2018. The impact of this change is shown in the table below. Three Months Ended September 30, Six Months Ended September 30, 2017 2017 Change in net revenue $ (78,761 ) $ (104,445 ) Change in income from operations (72,633 ) (96,364 ) Change in net income (66,245 ) (88,154 ) Change in earnings per share, basic $ (0.61 ) $ (0.82 ) Change in earnings per share, diluted $ (0.59 ) $ (0.81 ) Impairment of In-process Research & Development ("IPR&D") During the three months ended September 30, 2017 , as a result of our decision not to proceed with further development of certain IPR&D from the Social Point, S.L. ("Social Point") acquisition, we recognized an impairment charge of $11,257 in Depreciation and amortization expense in our Condensed Consolidated Statements of Operations. Recently Adopted Accounting Pronouncements Accounting for Stock Compensation In March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-09, Compensation—Stock Compensation . This new guidance identifies areas for simplification involving several aspects of accounting for share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. We adopted this update effective April 1, 2017. Upon adoption, using the modified retrospective transition method, we recognized previously unrecognized excess tax benefits as a deferred tax asset, which was fully offset by a valuation allowance, resulting in no net impact to retained earnings. Without the valuation allowance, our deferred tax asset would have increased by $24,594 . We elected to apply the change in presentation of excess tax benefits as an operating activity in the statement of cash flows prospectively and thus no prior periods were adjusted. We also elected to account for forfeitures as they occur using the modified retrospective transition method, which resulted in a cumulative effect adjustment of $323 to retained earnings (an increase in the accumulated deficit). The other aspects of the new guidance did not have a material effect on the Company’s consolidated financial statements. Accounting for Acquisitions or Disposals In January 2017, the FASB issued ASU 2017-01, Clarifying the Definition of a Business , with the objective of providing additional guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments in this update provide new guidance to determine when an integrated set of assets and activities (collectively referred to as a “set”) is not a business. The new guidance requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. The new guidance is expected to reduce the number of transactions that need to be further evaluated. The new standard, as amended, will be effective prospectively for interim and annual reporting periods beginning on January 1, 2018 (April 1, 2018 for the Company), with early adoption permitted. We adopted this update as of April 1, 2017. Recently Issued Accounting Pronouncements Accounting for Goodwill In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350) . This ASU eliminates Step 2 from the goodwill impairment test. Under the new guidance, an entity should perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. Additionally, this ASU eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. The amendments in this ASU are effective for fiscal years beginning after December 15, 2019 (April 1, 2020 for the Company), including interim periods within those fiscal years, and is applied on a prospective basis. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. While we are currently evaluating the impact of the adoption of this ASU, we do not believe that the adoption of this guidance will have a material impact on our consolidated financial statements. Accounting for Restricted Cash In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash . This ASU amends the presentation of restricted cash within the statement of cash flows. The new guidance requires that changes in restricted cash and cash equivalents be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts on the statement of cash flows. This standard will be effective for fiscal years beginning after December 15, 2017 (April 1, 2018 for the Company), including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the impact of the adoption of this ASU. Accounting for Leases In February 2016, the FASB issued ASU 2016-02, Leases . This new guidance requires lessees to recognize a right-of-use asset and a lease liability for virtually all leases (other than leases that meet the definition of a short-term lease). The liability will be equal to the present value of lease payments. The asset will be based on the liability, subject to adjustment, such as for initial direct costs. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. Operating leases will result in straight-line expense (similar to current operating leases) while finance leases will result in a front-loaded expense pattern (similar to current capital leases). Classification will be based on criteria that are largely similar to those applied in current lease accounting. This update is effective for annual periods, and interim periods within those years, beginning after December 15, 2018 (April 1, 2019 for the Company). This new guidance must be adopted using a modified retrospective approach whereby lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. Early adoption is permitted. We are currently evaluating the impact of adopting this update on our Consolidated Financial Statements, which will consist primarily of a balance sheet gross up of our operating leases, mostly for office space. Revenue from Contracts with Customers In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) . Under the new standard, revenue is recognized when a customer obtains control of promised goods or services and is recognized in an amount that reflects the consideration that the entity expects to receive in exchange for those goods or services. In addition, the standard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The FASB recently issued several amendments to the standard, including clarifications on disclosure of prior-period performance obligations and remaining performance obligations. The guidance permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the cumulative catch-up transition method). The new standard is effective for annual reporting periods, and interim periods within those annual periods, beginning after December 15, 2017 (April 1, 2018 for the Company), with early adoption permitted for annual reporting periods beginning after December 15, 2016 (April 1, 2017 for the Company). The Company will adopt the new standard effective April 1, 2018 using the cumulative catch-up transition method. We anticipate this standard will have a material impact on our Consolidated Financial Statements. While we are continuing to assess all potential impacts of the standard, we currently believe the most significant impact relates to our accounting for on-line enabled games that benefit from meaningful post-contract customer support ("PCS") such as unspecified content updates for which we do not have vendor-specific objective evidence of fair value ("VSOE"). Under the current accounting standards, for titles that do not have VSOE, we recognize the entire sales price ratably over the title's estimated service period. The VSOE requirement will be eliminated under the new standard. Accordingly, we may be required to recognize as revenue a portion of the sales price upon delivery of the software, as compared to the current requirement of recognizing the entire sales price ratably over an estimated offering period. It is possible that our evaluation of the expected impact of the new standard on certain transactions could change if there are additional interpretations of the new revenue guidance that are different from our preliminary conclusions.

MANAGEMENT AGREEMENT

MANAGEMENT AGREEMENT
MANAGEMENT AGREEMENT	MANAGEMENT AGREEMENT In May 2011, we entered into an amended management services agreement, (the "2011 Management Agreement") with ZelnickMedia Corporation ("ZelnickMedia") pursuant to which ZelnickMedia provided us with certain management, consulting and executive level services. In March 2014, we entered into a new management agreement, (the "2014 Management Agreement"), with ZelnickMedia pursuant to which ZelnickMedia continues to provide financial and management consulting services to the Company through March 31, 2019. The 2014 Management Agreement became effective April 1, 2014 and supersedes and replaces the 2011 Management Agreement, except as otherwise contemplated by the 2014 Management Agreement. As part of the 2014 Management Agreement, Strauss Zelnick, the President of ZelnickMedia, continues to serve as Executive Chairman and Chief Executive Officer, and Karl Slatoff, a partner of ZelnickMedia, continues to serve as President of the Company. The 2014 Management Agreement provides for an annual management fee of $2,970 over the term of the agreement and a maximum annual bonus opportunity of $4,752 over the term of the agreement, based on the Company achieving certain performance thresholds. In consideration for ZelnickMedia's services, we recorded consulting expense (a component of general and administrative expenses) of $2,524 and $1,336 during the three months ended September 30, 2017 and 2016 , respectively, and $3,861 and $2,673 during the six months ended September 30, 2017 and 2016 , respectively. We recorded stock-based compensation expense for non-employee restricted stock units granted to ZelnickMedia, which is included in general and administrative expenses of $13,863 and $6,907 during the three months ended September 30, 2017 and 2016 , respectively, and 19,877 and $10,796 during the six months ended September 30, 2017 and 2016 , respectively. In connection with the 2014 Management Agreement, we granted restricted stock units as follows: Six Months Ended September 30, 2017 2016 Time-based 66,122 107,551 Market-based(1) 122,370 199,038 Performance-based(1) New IP 20,396 33,174 Major IP 20,394 33,172 Total—Performance-based 40,790 66,346 Total Restricted Stock Units 229,282 372,935 _______________________________________________________________________________ (1) Represents the maximum number of shares eligible to vest. Time-based restricted stock units granted in 2017 will vest on April 4, 2019, and those granted in 2016 will vest on April 1, 2018, in each case provided that the 2014 Management Agreement has not been terminated prior to such vesting date. Market-based restricted stock units granted in 2017 are eligible to vest on April 4, 2019, and those granted in 2016 are eligible to vest on April 1, 2018, in each case provided that the 2014 Management Agreement has not been terminated prior to such vesting date. Market-based restricted stock units are eligible to vest based on the Company's Total Shareholder Return (as defined in the relevant grant agreement) relative to the Total Shareholder Return (as defined in the relevant grant agreement) of the companies that constitute the NASDAQ Composite Index as of the grant date measured over a two -year period. To earn the target number of market-based restricted stock units (which represents 50% of the number of the market-based restricted stock units set forth in the table above), the Company must perform at the 50th percentile, with the maximum number of market-based restricted stock units earned if the Company performs at the 75th percentile. Each reporting period we re-measure the fair value of the unvested shares of market-based restricted stock units granted to ZelnickMedia. Performance-based restricted stock units granted in 2017 are eligible to vest on April 4, 2019, and those granted in 2016 are eligible to vest on April 1, 2018, in each case provided that the 2014 Management Agreement has not been terminated prior to such vesting date. Performance-based restricted stock units, of which 50% are tied to "New IP" and 50% to "Major IP" (as defined in the relevant grant agreement), are eligible to vest based on the Company's achievement of certain performance metrics (as defined in the relevant grant agreement) of individual product releases of "New IP" or "Major IP" measured over a two -year period. The target number of performance-based restricted stock units that may be earned pursuant to these grants is equal to 50% of the grant amounts set forth in the above table (the numbers in the table represent the maximum number of performance-based restricted stock units that may be earned). Each reporting period we assess the performance metric and upon achievement of certain thresholds record an expense for the unvested portion of the shares of performance-based restricted stock units. Certain performance metrics, based on unit sales, have been achieved as of September 30, 2017 for the "Major IP" performance-based restricted stock units granted in 2017 and 2016 . The unvested portion of time-based, market-based and performance-based restricted stock units held by ZelnickMedia were 602,217 and 898,526 as of September 30, 2017 and March 31, 2017 , respectively. In addition to the restricted stock units granted to ZelnickMedia, 478,839 restricted stock units vested and 46,752 restricted stock units were forfeited during the six months ended September 30, 2017 .

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	6 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS The carrying amounts of our financial instruments, including cash and cash equivalents, restricted cash, accounts receivable, accounts payable and accrued expenses and other current liabilities, approximate fair value because of their short maturities. We follow a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. This hierarchy requires entities to maximize the use of "observable inputs" and minimize the use of "unobservable inputs." The three levels of inputs used to measure fair value are as follows: • Level 1—Quoted prices in active markets for identical assets or liabilities. • Level 2—Observable inputs other than quoted prices included in Level 1, such as quoted prices for markets that are not active or other inputs that are observable or can be corroborated by observable market data. • Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.

During the three months ended September 30, 2017 , we recognized a reduction to general and administrative expense of $7,012 for the decrease in fair value of the contingent consideration liability associated with the Social Point acquisition, which reduced the fair value of the contingent consideration liability to $135 after the impact of foreign exchange. The reduction resulted from the lower probability of Social Point achieving certain performance measures in the 12 and 24 -month periods following the acquisition. We did not have any transfers between Level 1 and Level 2 fair value measurements, nor did we have any transfers into or out of Level 3 during the six months ended September 30, 2017 . Debt As of September 30, 2017 , the estimated fair value of our 1.00% Convertible Notes due 2018 (the " 1.00% Convertible Notes") was $257,627 . The fair value was determined using Level 2 inputs, observable market data, for the 1.00% Convertible Notes and their embedded option feature. See Note 9 for additional information regarding our 1.00% Convertible Notes.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES Our risk management strategy includes the use of derivative financial instruments to reduce the volatility of earnings and cash flows associated with changes in foreign currency exchange rates. We do not enter into derivative financial contracts for speculative or trading purposes. We recognize derivative instruments as either assets or liabilities on our Condensed Consolidated Balance Sheets, and we measure those instruments at fair value. We classify cash flows from derivative transactions as cash flows from operating activities in our Condensed Consolidated Statements of Cash Flows. Foreign currency forward contracts The following table shows the gross notional amounts of foreign currency forward contracts: September 30, 2017 March 31, 2017 Forward contracts to sell foreign currencies $ 113,762 $ 177,549 Forward contracts to purchase foreign currencies 3,319 9,170 For the three months ended September 30, 2017 and 2016 , we recorded a loss of $6,102 and $225 , respectively, and for the six months ended September 30, 2017 and 2016 , we recorded a loss of $14,705 and a gain $573 , respectively, related to foreign currency forward contracts in Interest and other, net in our Condensed Consolidated Statements of Operations. Our foreign currency exchange forward contracts are not designated as hedging instruments under hedge accounting and are used to reduce the impact of foreign currency on certain balance sheet exposures and certain revenue and expense. These instruments are generally short term in nature, with typical maturities of less than one year, and are subject to fluctuations in foreign exchange rates. Cross-currency swaps We entered into a cross-currency swap agreement during the three months ended September 30, 2017 related to an intercompany loan that has been designated and accounted for as a cash flow hedge of foreign currency exchange risk. The intercompany loan is related to the acquisition of Social Point. As of September 30, 2017 , the notional amount of the cross-currency swap is $129 million . This cross-currency swap mitigates the exposure to fluctuations in the U.S. dollar-euro exchange rate related to the intercompany loan. The critical terms of the cross-currency swap agreement correspond to the intercompany loan and both mature at the same time in 2027; as such there was no ineffectiveness during the period. Changes in the fair value of this cross-currency swap are recorded in Accumulated other comprehensive income (loss) and offset the change in value of interest and principal payment as a result of changes in foreign exchange rates. Resulting gains or losses from the cross-currency swap are reclassified from Accumulated other comprehensive income (loss) to earnings to completely offset foreign currency transaction gains and losses recognized on the intercompany loan. We recognize the difference between the U.S. dollar interest payments received from the swap counterparty and the U.S. dollar equivalent of the euro interest payments made to the swap counterparty in interest and other, net on our Condensed Consolidated Statement of Operations. There are no credit-risk related contingent features associated with these swaps.

Liability Awards During the three months ended September 30, 2017 , we reclassified 5,550,000 time and performance based restricted stock units as equity awards. These awards were granted in prior periods and historically accounted for as liability awards as they previously could be settled only in cash and based on a contractually stipulated cash settlement value. However, in September 2017 at our Annual Meeting of Stockholders, we received stockholder approval to increase the number of shares of Common Stock for which awards may be granted and therefore now have the ability and intent to settle these awards in stock. As a result, we reclassified $74,707 from Other long-term liabilities to Additional paid-in capital within Stockholders' equity. Additionally, we recognized incremental cost of $112,789 to reflect the difference between the share price at the time of the modification and the contractually stipulated cash settlement value. Of these incremental costs, $84,176 was capitalized within Software development costs and licenses, net of current porti on; $23,251 was recorded within Software development costs and royalties (a component of cost of goods sold); and $5,361 was recorded within Research and development costs . These awards are expected to vest between fiscal 2019 and fiscal 2022. As of September 30, 2017 , the unrecognized compensation cost for these awards is $364,993 .

Debt Disclosure [Abstract]
DEBT	DEBT Credit Agreement In April 2016, we entered into a Sixth Amendment to our Second Amended and Restated Credit Agreement (as amended, the "Credit Agreement"). The Credit Agreement provides for borrowings of up to $100,000 which may be increased by up to $100,000 pursuant to the terms of the Credit Agreement and which is secured by substantially all of our assets and the equity of our subsidiaries. The Credit Agreement expires on August 18, 2019. Revolving loans under the Credit Agreement bear interest at our election of (a) 0.25% to 0.75% above a certain base rate ( 4.25% at September 30, 2017 ) or (b) 1.25% to 1.75% above the LIBOR Rate (approximately 1.24% at September 30, 2017 ), with the margin rate subject to the achievement of certain average liquidity levels. We are also required to pay a monthly fee on the unused available balance, ranging from 0.25% to 0.375% based on availability. We had no outstanding borrowings at September 30, 2017 and March 31, 2017 . Availability under the Credit Agreement is unrestricted when liquidity, as defined in the Credit Agreement, is at least $300,000 . When liquidity is below $300,000 availability under the Credit Agreement is restricted by our United States and United Kingdom based accounts receivable and inventory balances. The Credit Agreement also allows for the issuance of letters of credit in an aggregate amount of up to $5,000 . Information related to availability on our Credit Agreement is as follows: September 30, 2017 March 31, 2017 Available borrowings $ 98,306 $ 98,320 Outstanding letters of credit 1,664 1,664 We recorded interest expense and fees related to the Credit Agreement of $111 and $111 , respectively for the three months ended September 30, 2017 and 2016 and $221 and $221 for the six months ended September 30, 2017 and 2016 , respectively. The Credit Agreement contains covenants that substantially limit us and our subsidiaries' ability to create, incur, assume or be liable for indebtedness; dispose of assets outside the ordinary course of business; acquire, merge or consolidate with or into another person or entity; create, incur or allow any lien on any of their respective properties; make investments; or pay dividends or make distributions (each subject to certain limitations); or optionally prepay any indebtedness (subject to certain exceptions, including an exception permitting the redemption of our unsecured convertible senior notes upon the meeting of certain minimum liquidity requirements). In addition, the Credit Agreement provides for certain events of default such as nonpayment of principal and interest, breaches of representations and warranties, noncompliance with covenants, acts of insolvency, default on indebtedness held by third parties and default on certain material contracts (subject to certain limitations and cure periods). The Credit Agreement also contains a requirement that we maintain an interest coverage ratio of more than one to one for the trailing twelve -month period, if certain average liquidity levels fall below $30,000 . 1.00% Convertible Notes Due 2018 On June 18, 2013, we issued $250,000 aggregate principal amount of 1.00% Convertible Notes due 2018. The 1.00% Convertible Notes were issued at 98.5% of par value for proceeds of $246,250 . Interest on the 1.00% Convertible Notes is payable semi-annually in arrears on July 1st and January 1st of each year, commencing on January 1, 2014. The 1.00% Convertible Notes mature on July 1, 2018, unless earlier repurchased by the Company or converted. We do not have the right to redeem the 1.00% Convertible Notes prior to maturity. We also granted the underwriters a 30 -day option to purchase up to an additional $37,500 principal amount of 1.00% Convertible Notes to cover overallotments, if any. On July 17, 2013, we closed our public offering of $37,500 principal amount of our 1.00% Convertible Notes as a result of the underwriters exercising their overallotment option in full on July 12, 2013, bringing the total proceeds to $283,188 . The 1.00% Convertible Notes are convertible at an initial conversion rate of 46.4727 shares of our common stock per $1 principal amount of 1.00% Convertible Notes (representing an initial conversion price of approximately $21.52 per share of common stock for a total of approximately 13,361,000 underlying conversion shares) subject to adjustment in certain circumstances. Holders may convert the 1.00% Convertible Notes at their option prior to the close of business on the business day immediately preceding January 1, 2018 only under the following circumstances: (1) during any fiscal quarter commencing after September 30, 2013, if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the preceding fiscal quarter is greater than or equal to 130% of the applicable conversion price on each applicable trading day; (2) during the five business day period after any 10 consecutive trading day period (the "measurement period") in which the trading price per $1 principal amount of 1.00% Convertible Notes for each day of that measurement period was less than 98% of the product of the last reported sale price of our common stock and the applicable conversion rate on each such day; or (3) upon the occurrence of specified corporate events. On and after January 1, 2018 until the close of business on the business day immediately preceding the maturity date, holders may convert their 1.00% Convertible Notes at any time, regardless of the foregoing circumstances. Upon conversion, the 1.00% Convertible Notes may be settled, at our election, in cash, shares of our common stock, or a combination of cash and shares of our common stock. Our common stock price exceeded 130% of the applicable conversion price per share for at least 20 trading days during the 30 consecutive trading days ended September 30, 2017 . Accordingly, as of October 1, 2017, the 1.00% Convertible Notes may be converted at the holder's option through December 31, 2017. During the three and six months ended September 30, 2017, 1.00% Convertible Notes with an aggregate principal amount of $169,436 and $213,898 were settled, and an additional $2,104 were tendered for conversion with October 2017 settlement dates. We elected to settle in shares of our common stock. Our intent and ability, given our option, would be to settle future conversions in shares of our common stock. As such, we have continued to classify these 1.00% Convertible Notes as long-term debt. Upon the occurrence of certain fundamental changes involving the Company, holders of the 1.00% Convertible Notes may require us to purchase all or a portion of their 1.00% Convertible Notes for cash at a price equal to 100% of the principal amount of the notes to be purchased, plus accrued and unpaid interest (including additional interest, if any) to, but excluding, the fundamental change purchase date. The indenture governing the 1.00% Convertible Notes contains customary terms and covenants and events of default. If an event of default (as defined therein) occurs and is continuing, the Trustee by notice to the Company, or the holders of at least 25% in aggregate principal amount of the 1.00% Convertible Notes then outstanding by notice to the Company and the Trustee, may, and the Trustee at the request of such holders shall, declare 100% of the principal of and accrued and unpaid interest (including additional interest, if any) on all the 1.00% Convertible Notes to be due and payable. In the case of an event of default arising out of certain bankruptcy events, 100% of the principal of and accrued and unpaid interest (including additional interest, if any), on the 1.00% Convertible Notes will automatically become due and payable immediately. The 1.00% Convertible Notes are senior unsecured obligations and rank senior in right of payment to our existing and future indebtedness that is expressly subordinated in right of payment to the 1.00% Convertible Notes; equal in right of payment to our existing and future indebtedness that is not so subordinated; effectively junior in right of payment to any of our secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all existing and future indebtedness incurred by our subsidiaries. We separately account for the liability and equity components of the 1.00% Convertible Notes in a manner that reflects our nonconvertible debt borrowing rate. We estimated the fair value of the 1.00% Convertible Notes to be $225,567 upon issuance of our 1.00% Convertible Notes, assuming a 6.15% non-convertible borrowing rate. The carrying amount of the equity component was determined to be approximately $57,621 by deducting the fair value of the liability component from the net proceeds of the 1.00% Convertible Notes. The excess of the principal amount of the liability component over its carrying amount is amortized to interest and other, net over the term of the 1.00% Convertible Notes using the effective interest method. The equity component is not remeasured as long as it continues to meet the conditions for equity classification. In accounting for the $2,815 of banking, legal and accounting fees related to the issuance of the 1.00% Convertible Notes, we allocated $2,209 to the liability component and $606 to the equity component. Debt issuance costs attributable to the liability component are being amortized to interest and other, net over the term of the 1.00% Convertible Notes, and issuance costs attributable to the equity component were netted with the equity component in additional paid-in capital. As of September 30, 2017 and March 31, 2017 , the if-converted value of our 1.00% Convertible Notes exceeded the principal amount of $54,252 and $268,149 , respectively by $203,376 and $470,456 , respectively. The following table provides additional information related to our 1.00% Convertible Notes: September 30, 2017 March 31, 2017 Additional paid-in capital $ 35,784 $ 35,784 Principal amount of 1.00% Convertible Notes $ 54,252 $ 268,149 Unamortized discount of the liability component 1,837 15,751 Carrying amount of debt issuance costs 46 469 Net carrying amount of 1.00% Convertible Notes $ 52,369 $ 251,929 The following table provides the components of interest expense related to our 1.00% Convertible Notes: Three Months Ended September 30, Six Months Ended September 30, 2017 2016 2017 2016 Cash interest expense (coupon interest expense) $ 130 $ 698 $ 579 $ 1,417 Non-cash amortization of discount on 1.00% Convertible Notes 8,678 3,869 13,915 7,004 Amortization of debt issuance costs 263 127 423 234 Total interest expense related to 1.00% Convertible Notes $ 9,071 $ 4,694 $ 14,917 $ 8,655

The calculation of EPS for common stock under the two-class method shown above for the six months ended September 30, 2017 excludes income attributable to the participating securities from the numerator and excludes the dilutive effect of those awards from the denominator. We incurred a net loss for the three months ended September 30, 2017 and the six months ended September 30, 2016 ; therefore, the basic and diluted weighted average shares outstanding for those periods exclude the effect of the unvested share-based awards that are considered participating securities and all common stock equivalents because their effect would be antidilutive. For the three months ended September 30, 2017 and the six months ended September 30, 2016 , we had 2,145,000 and 5,172,000 , respectively, of unvested share-based awards that are excluded from the EPS calculation due to the net loss for those periods. We define common stock equivalents as restricted stock awards and common stock related to the Convertible Notes (see Note 9) outstanding during the period. Common stock equivalents are measured using the treasury stock method, except for the Convertible Notes, which are assessed for their effect on diluted EPS using the more dilutive of the treasury stock method or the if-converted method. Under the provisions of the if-converted method, the Convertible Notes are assumed to be converted and included in the denominator of the EPS calculation and the interest expense, net of tax, recorded in connection with the Convertible Notes is added back to the numerator. During the six months ended September 30, 2017 , 2,700,000 restricted stock awards vested, we granted 600,000 unvested restricted stock awards, and 14,000 unvested restricted stock awards were forfeited.

While it is reasonably possible that a loss may be incurred in excess of the amounts accrued in our financial statements, we believe that such losses, unless otherwise disclosed, would not be material. On April 11, 2016, we filed a declaratory judgment action in the United States District Court for the Southern District of New York seeking, among other things, a judicial declaration that Leslie Benzies, the former president of one of our subsidiaries with whom we had been in ongoing discussions regarding his separation of employment, is not entitled to any minimum allocation or financial parity with any other person under the applicable royalty plan. We believe we will prevail in this matter, although there can be no assurance of the outcome. On April 12, 2016, Mr. Benzies filed a complaint in the Supreme Court of the State of New York, New York County against us, and certain of our subsidiaries and employees. We removed this case to the United States District Court for the Southern District of New York, but the case was subsequently remanded to state court. The complaint claims damages of at least $150,000 and contains allegations of breach of fiduciary duty; fraudulent inducement and fraudulent concealment; aiding and abetting breach of fiduciary duty; breach of various contracts; breach of implied duty of good faith and fair dealing; tortious interference with contract; unjust enrichment; reformation; constructive trust; declaration of rights; constructive discharge; defamation and fraud. Motion practice in both the federal and state actions is ongoing. While we believe that we have meritorious defenses to these claims, and we intend to vigorously defend against them and to pursue any counterclaims, we have accrued what we believe to be an adequate amount for this matter, which amounts are classified as Business reorganization within Accrued expenses and other current liabilities in our Condensed Consolidated Balance Sheet (see Note 8). We do not believe that the ultimate outcome of such litigation, even if in excess of our current accrual, will have a material adverse effect on our business, financial condition or results of operations.

Restructuring and Related Activities [Abstract]
BUSINESS REORGANIZATION	BUSINESS REORGANIZATION In the first quarter of fiscal 2018, we announced and initiated actions to implement a strategic reorganization at one of our labels (the "2018 Plan"). In connection with this initiative, we incurred business reorganization expenses of $1,713 during the three months ended September 30, 2017 due to true-up of estimates for employee separation costs and $12,312 during the six months ended September 30, 2017 due primarily to employee separation costs. Through September 30, 2017 , we paid $2,547 related to these reorganization activities. As of September 30, 2017 , $5,002 remained accrued for in Accrued expenses and other current liabilities and $4,763 in Other non-current liabilities. Although we may record additional expense or benefit in future periods to true-up estimates, we do not expect to incur additional reorganization costs in connection with the 2018 Plan.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The benefit from income taxes for the three months ended September 30, 2017 is based on our projected annual effective tax rate for fiscal year 2018, adjusted for specific items that are required to be recognized in the period in which they are incurred. The benefit from income taxes was $11.6 million for the three months ended September 30, 2017 as compared to a provision of $3.7 million for the prior year period. When compared to the statutory rate of 35% , the effective tax rate of 80.9% for the three months ended September 30, 2017 , was primarily due to the adoption of ASU 2016-09, Compensation - Stock Compensation, as of April 1, 2017, which required us to recognize $8.0 million of excess tax benefits from employee stock compensation as a component of the benefit from income taxes (previously excess tax benefit and tax deficiencies were recognized in additional paid-in-capital), as well as $2.5 million of tax benefits related to the reduction in a contingent consideration liability associated with the Social Point acquisition, partially offset by a $5.0 million decrease in the projected benefit related to tax credits. The benefit from income taxes reported for the six months ended September 30, 2017 is based on our projected annual effective tax rate for fiscal year 2018, adjusted for specific items that are required to be recognized in the period in which they are incurred. The benefit from income taxes was $24.4 million for the six months ended September 30, 2017 , as compared to a provision of $0.1 million for the prior year period. When compared to the statutory rate of 35% , the effective tax rate of (73.7)% for the six months ended September 30, 2017 was primarily due to the adoption of ASU 2016-09, Compensation - Stock Compensation , as of April 1, 2017, which required us to recognize $24.5 million of excess tax benefits from employee stock compensation as a component of the benefit from income taxes (previously excess tax benefit and tax deficiencies were recognized in additional paid-in-capital), $5.5 million of tax benefits from tax credits, and $5.4 million of tax benefits due to changes in our valuation allowance, as well as the mix of projected pre-tax income. We are regularly examined by domestic and foreign taxing authorities. Examinations may result in tax assessments in excess of amounts claimed and the payment of additional taxes. We believe our tax positions comply with applicable tax law, and that we have adequately provided for reasonably foreseeable tax assessments. It is possible that settlement of audits or the expiration of the statute of limitations may impact our effective tax rate in future periods.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying Condensed Consolidated Financial Statements are unaudited and include the accounts of the Company and its wholly-owned subsidiaries and, in the opinion of management, reflect all normal and recurring adjustments necessary for the fair presentation of our financial position, results of operations and cash flows. Interim results may not be indicative of the results that may be expected for the full fiscal year. All inter-company accounts and transactions have been eliminated in consolidation. The preparation of these Condensed Consolidated Financial Statements in accordance with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in these Condensed Consolidated Financial Statements and accompanying notes. As permitted under generally accepted accounting principles in the United States, interim accounting for certain expenses, including income taxes, are based on full year assumptions when appropriate. Actual results could differ materially from those estimates. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been omitted pursuant to the rules and regulations of the Securities and Exchange Commission, although we believe that the disclosures are adequate to make the information presented not misleading. These Condensed Consolidated Financial Statements and accompanying notes should be read in conjunction with our annual consolidated financial statements and the notes thereto, included in our Annual Report on Form 10-K for the fiscal year ended March 31, 2017 . Certain immaterial reclassifications have been made to prior period amounts to conform to the current period presentation.
Revenue Recognition	Revenue Recognition As part of our on-going assessment of estimated service periods, in June 2017, we extended Grand Theft Auto V's estimated service period from 41 through 50 months, or through December 2018.
Recently Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements Accounting for Stock Compensation In March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-09, Compensation—Stock Compensation . This new guidance identifies areas for simplification involving several aspects of accounting for share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. We adopted this update effective April 1, 2017. Upon adoption, using the modified retrospective transition method, we recognized previously unrecognized excess tax benefits as a deferred tax asset, which was fully offset by a valuation allowance, resulting in no net impact to retained earnings. Without the valuation allowance, our deferred tax asset would have increased by $24,594 . We elected to apply the change in presentation of excess tax benefits as an operating activity in the statement of cash flows prospectively and thus no prior periods were adjusted. We also elected to account for forfeitures as they occur using the modified retrospective transition method, which resulted in a cumulative effect adjustment of $323 to retained earnings (an increase in the accumulated deficit). The other aspects of the new guidance did not have a material effect on the Company’s consolidated financial statements. Accounting for Acquisitions or Disposals In January 2017, the FASB issued ASU 2017-01, Clarifying the Definition of a Business , with the objective of providing additional guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments in this update provide new guidance to determine when an integrated set of assets and activities (collectively referred to as a “set”) is not a business. The new guidance requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. The new guidance is expected to reduce the number of transactions that need to be further evaluated. The new standard, as amended, will be effective prospectively for interim and annual reporting periods beginning on January 1, 2018 (April 1, 2018 for the Company), with early adoption permitted. We adopted this update as of April 1, 2017. Recently Issued Accounting Pronouncements Accounting for Goodwill In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350) . This ASU eliminates Step 2 from the goodwill impairment test. Under the new guidance, an entity should perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. Additionally, this ASU eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. The amendments in this ASU are effective for fiscal years beginning after December 15, 2019 (April 1, 2020 for the Company), including interim periods within those fiscal years, and is applied on a prospective basis. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. While we are currently evaluating the impact of the adoption of this ASU, we do not believe that the adoption of this guidance will have a material impact on our consolidated financial statements. Accounting for Restricted Cash In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash . This ASU amends the presentation of restricted cash within the statement of cash flows. The new guidance requires that changes in restricted cash and cash equivalents be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts on the statement of cash flows. This standard will be effective for fiscal years beginning after December 15, 2017 (April 1, 2018 for the Company), including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the impact of the adoption of this ASU. Accounting for Leases In February 2016, the FASB issued ASU 2016-02, Leases . This new guidance requires lessees to recognize a right-of-use asset and a lease liability for virtually all leases (other than leases that meet the definition of a short-term lease). The liability will be equal to the present value of lease payments. The asset will be based on the liability, subject to adjustment, such as for initial direct costs. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. Operating leases will result in straight-line expense (similar to current operating leases) while finance leases will result in a front-loaded expense pattern (similar to current capital leases). Classification will be based on criteria that are largely similar to those applied in current lease accounting. This update is effective for annual periods, and interim periods within those years, beginning after December 15, 2018 (April 1, 2019 for the Company). This new guidance must be adopted using a modified retrospective approach whereby lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. Early adoption is permitted. We are currently evaluating the impact of adopting this update on our Consolidated Financial Statements, which will consist primarily of a balance sheet gross up of our operating leases, mostly for office space. Revenue from Contracts with Customers In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) . Under the new standard, revenue is recognized when a customer obtains control of promised goods or services and is recognized in an amount that reflects the consideration that the entity expects to receive in exchange for those goods or services. In addition, the standard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The FASB recently issued several amendments to the standard, including clarifications on disclosure of prior-period performance obligations and remaining performance obligations. The guidance permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the cumulative catch-up transition method). The new standard is effective for annual reporting periods, and interim periods within those annual periods, beginning after December 15, 2017 (April 1, 2018 for the Company), with early adoption permitted for annual reporting periods beginning after December 15, 2016 (April 1, 2017 for the Company). The Company will adopt the new standard effective April 1, 2018 using the cumulative catch-up transition method. We anticipate this standard will have a material impact on our Consolidated Financial Statements. While we are continuing to assess all potential impacts of the standard, we currently believe the most significant impact relates to our accounting for on-line enabled games that benefit from meaningful post-contract customer support ("PCS") such as unspecified content updates for which we do not have vendor-specific objective evidence of fair value ("VSOE"). Under the current accounting standards, for titles that do not have VSOE, we recognize the entire sales price ratably over the title's estimated service period. The VSOE requirement will be eliminated under the new standard. Accordingly, we may be required to recognize as revenue a portion of the sales price upon delivery of the software, as compared to the current requirement of recognizing the entire sales price ratably over an estimated offering period. It is possible that our evaluation of the expected impact of the new standard on certain transactions could change if there are additional interpretations of the new revenue guidance that are different from our preliminary conclusions.
