| Impact of recently issued accounting standards                   | Impact of Recently Issued Accounting StandardsIn March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, related to simplifications of employee share-based payment accounting. This pronouncement eliminates the APIC pool concept and requires that excess tax benefits and tax deficiencies be recorded in the income statement when awards are settled. The pronouncement also addresses simplifications related to statement of cash flows classification, accounting for forfeitures, and minimum statutory tax withholding requirements. The pronouncement is effective for annual periods (and for interim periods within those annual periods) beginning after December 15, 2016. We will adopt this new standard in the first quarter of fiscal year 2018. We are currently evaluating the impact of this new standard on our Consolidated Financial Statements and related disclosures.In November 2016, FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force), which requires amounts generally described as restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown in the statement of cash flows. This update is effective for annual periods (and interim periods within those annual periods) beginning after December 15, 2017. Early adoption is permitted. We are currently evaluating the timing of adoption and impact of this new standard on our Consolidated Statements of Cash Flows.In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This update is intended to reduce the existing diversity in practice in how certain transactions are classified in the statement of cash flows. This update is effective for annual periods (and interim periods within those annual periods) beginning after December 15, 2017. Early adoption is permitted, provided that all of the amendments are adopted in the same period. We are currently evaluating the timing of adoption and impact of this new standard on our Consolidated Statements of Cash Flows. In March 2016, the FASB issued ASU 2016-04, Liabilities – Extinguishments of Liabilities (Subtopic 405-20): Recognition of Breakage for Certain Prepaid Stored-Value Products. The amendments in the ASU are designed to provide guidance and eliminate diversity in the accounting for derecognition of prepaid stored-value product liabilities. Typically, a prepaid stored-value product liability is to be derecognized when it is probable that a significant reversal of the recognized breakage amount will not subsequently occur. This is when the likelihood of the product holder exercising its remaining rights becomes remote. This estimate shall be updated at the end of each period. The amendments in this ASU are effective for annual periods (and interim periods within those annual periods) beginning after December 15, 2017. Early adoption is permitted. We are currently evaluating the timing of adoption and impact of this new standard on our Consolidated Financial Statements and related disclosures.In January 2016, the FASB issued ASU 2016-01, Financial Instruments (Topic 825-10), which requires that most equity investments be measured at fair value, with subsequent changes in fair value recognized in net income. The ASU also impacts financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments.The requirements will be effective for annual periods (and interim periods within those annual periods) beginning after December 15, 2017. We are currently evaluating the impact of this new standard on our Consolidated Financial Statements and related disclosures. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The standard permits the use of either the retrospective or cumulative effect transition method. We currently anticipate adopting the standard using the cumulative effect transition method. This new revenue standard, as amended by ASU 2015-14, is effective in the first quarter of fiscal year 2019. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers: Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which clarifies the guidance in the new revenue standard on assessing whether an entity is a principal or an agent in a revenue transaction. This conclusion impacts whether an entity reports revenue on a gross or net basis. In April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing, which clarifies the guidance in the new revenue standard regarding an entity’s identification of its performance obligations in a contract, as well as an entity’s evaluation of the nature of its promise to grant a license of intellectual property and whether or not that revenue is recognized over time or at a point in time. In May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers: Narrow-Scope Improvements and Practical Expedients, which amends the guidance in the new revenue standard on collectibility, noncash consideration, presentation of sales tax, and transition. The amendments are intended to address implementation issues that were raised by stakeholders and provide additional practical expedients to reduce the cost and complexity of applying the new revenue standard. These amendments have the same effective date as the new revenue standard. While we are currently evaluating the impact of the new revenue standard, as amended, on our Consolidated Financial Statements and related disclosures, we believe the adoption of the new standard will have a significant impact on the accounting for certain transactions with multiple elements or “bundled” arrangements (for example, sales of online-enabled games for which we do not have vendor-specific objective evidence of fair value (“VSOE”) for unspecified future updates) because the requirement to have VSOE for undelivered elements under current accounting standards is 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. In addition, based upon what we expect to be our performance obligations under the new standard, as amended, we believe that upon adoption, a larger portion of our bundled arrangements will be presented as service revenue instead of product revenue in our Consolidated Statements of Operations. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The FASB issued this 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. The updated guidance is effective for annual periods beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption of the update is permitted. We are currently evaluating the timing of adoption and impact of this new standard on our Consolidated Financial Statements and related disclosures.In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326). The standard changes the methodology for measuring credit losses on financial instruments and the timing of when such losses are recorded. ASU 2016-13 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019. Early adoption is permitted for fiscal years, and interim periods within those years, beginning after December 15, 2018. We are currently evaluating the timing of adoption and impact of this new standard on our Consolidated Financial Statements and related disclosures. |
