New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued Accounting Pronouncements	Recently issued accounting pronouncements Recently adopted accounting pronouncements Inventory In July 2015, the FASB issued new guidance related to the measurement of inventory which requires inventory within the scope of the guidance to be measured at the lower of cost and net realizable value. Net realizable value is defined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. We adopted this new standard as of January 1, 2017, and applied it prospectively. The adoption of this guidance did not have a material impact on our financial statements. Recent accounting pronouncements not yet adopted Revenue recognition In May 2014, the FASB issued new accounting guidance related to revenue recognition. The new standard will replace all current U.S. GAAP guidance on this topic and eliminate all industry-specific guidance, providing a unified model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue upon the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled to in exchange for those goods or services. This guidance will be effective for fiscal years and interim periods within those years beginning after December 15, 2017, and can be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. As previously disclosed, we believe the adoption of the new revenue recognition standard may have a significant impact on the accounting for our sales of our games with significant online functionality for which we do not have vendor-specific objective evidence ("VSOE") for unspecified future updates and ongoing online services provided. Under the current accounting standards, VSOE for undelivered elements is required. This 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. This potential difference may have a material impact on our consolidated financial statements upon adoption of this new guidance. We are continuing to evaluate the adoption method that we will utilize as well as the additional impacts of this new accounting guidance on our financial statements and related disclosures. Leases In February 2016, the FASB issued new guidance related to the accounting for leases. The new standard will replace all current U.S. GAAP guidance on this topic. The new standard, among other things, requires a lessee to classify a lease as either an operating or financing lease and lessees will need to recognize a lease liability and a right-of-use asset for their leases. The liability will be equal to the present value of lease payments. The asset will be based on the liability, subject to adjustment for initial direct costs, lease incentives received, and any prepaid lease payments. Operating leases will result in a straight-line expense pattern, while finance leases will result in a front-loaded expense pattern. Classification will be based on criteria that are largely similar to those applied in current lease accounting. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted. The new standard must be adopted using a modified retrospective transition and will require application of the new guidance at the beginning of the earliest comparative period presented. We are evaluating the impact of this new accounting guidance on our financial statements. Financial Instruments In January 2016, the FASB issued new guidance related to the recognition and measurement of financial assets and financial liabilities. The new standard, amongst other things, generally requires companies to measure investments in other entities, except those accounted for under the equity method, at fair value and recognize any changes in fair value in net income. The new standard also simplifies the impairment assessment of equity investments without readily determinable fair values. The new standard is effective for fiscal years beginning after December 15, 2017, and the guidance should be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity investments without readily determinable fair values (including disclosure requirements) should be applied prospectively to equity investments that exist as of the date of adoption. We are evaluating the impact of this new accounting guidance on our financial statements. Statement of Cash Flows-Restricted Cash In November 2016, the FASB issued new guidance related to the classification of restricted cash in the statement of cash flows. The new standard requires that a statement of cash flows explain any change during the period in total cash, cash equivalents, and restricted cash. Therefore, restricted cash will be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The new standard is effective for fiscal years beginning after December 15, 2018, and should be applied retrospectively. Early adoption is permitted. We are evaluating the impact, if any, of adopting this new accounting guidance on our financial statements. We expect there would be a significant impact to the condensed consolidated statements of cash flows for the three months ended March 31, 2016, as this period includes, as an investing activity, the $3.6 billion movement in restricted cash as a result of transferring cash into escrow at December 31, 2015 to facilitate the King Acquisition and the subsequent release of that cash in 2016 in connection with the King Acquisition. Under this new standard, the restricted cash balance would be included in the beginning and ending total cash, cash equivalents, and restricted cash balances and, hence, would not be included as an investing activity in the statement of cash flows. Goodwill In January 2017, the FASB issued new guidance which eliminates Step 2 from the goodwill impairment test. Instead, if any entity forgoes a Step 0 test, an entity will be required to perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit, as determined in Step 1 from the goodwill impairment test, with its carrying amount and recognize an impairment charge, if any, for the amount by which the carrying amount exceeds the reporting unit's fair value, not to exceed the total amount of goodwill allocated to the reporting unit. The new standard is effective for fiscal years beginning after December 15, 2019 and should be applied prospectively. Early adoption is permitted. We are evaluating the impact, if any, of adopting this new accounting guidance on our consolidated financial statements.
