Description of the Business and Summary of Significant Accounting Policies	Description of the Business and Summary of Significant Accounting Policies Description of the Business We are a leading developer of technology‑based products and services and associated content for the worldwide gaming, lottery and interactive gaming industries. Our portfolio includes gaming machines and game content, casino management systems, table game products and services, instant and draw‑based lottery games, server‑based gaming and lottery systems, sports betting technology, lottery content and services, loyalty and rewards programs, interactive gaming and social casino solutions. We also gain access to technologies and pursue global expansion through strategic acquisitions and equity investments. We report our operations in three business segments—Gaming, Lottery and Interactive. Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements of the Company have been prepared in accordance with SEC and U.S. GAAP requirements. All monetary values set forth in these financial statements are in United States dollars ("USD" or "$") unless otherwise stated herein. The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, as well as those subsidiaries in which we have a controlling financial interest. Investments in other entities in which we do not have a controlling financial interest but we exert significant influence are accounted for in our consolidated financial statements using the equity method of accounting. All intercompany balances and transactions have been eliminated in consolidation. We have evaluated subsequent events through the date these financial statements were issued. In the opinion of management, we have made all adjustments necessary to present fairly our consolidated financial position, results of operations and comprehensive loss and cash flows for the periods presented. Such adjustments are of a normal, recurring nature. These unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in our 2015 Annual Report on Form 10-K. Interim results of operations are not necessarily indicative of results of operations for a full year. Significant Accounting Policies There have been no changes to our significant accounting policies described in Note 1 (Description of the Business and Summary of Significant Accounting Policies) in our 2015 Annual Report on Form 10-K. New Accounting Guidance - Recently Adopted In March 2016, the FASB issued ASU No. 2016-07, Investments - Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting. The amended guidance simplifies the accounting for equity investments and eliminates the requirements in Topic 323 that an entity retroactively adopt the equity method of accounting if an investment qualifies for use of the equity method as a result of an increase in the level of ownership or degree of influence. The amendment requires that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor's previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. The amendment also requires that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. ASU 2016-07 is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years, with earlier adoption permitted. The prospective adoption of the ASU is required. We adopted this guidance during the first quarter of 2016. The adoption of this guidance did not have a material effect on our financial condition, results of operations or cash flows. New Accounting Guidance - Not Yet Adopted In May 2014, the FASB issued ASU No. 2014-09 (Topic 606), Revenue from Contracts with Customers. The amended guidance outlines a single comprehensive revenue model for entities to use in accounting for revenue from contracts with customers. The guidance supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that "an entity recognizes 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." In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which defers the effective date of ASU 2014-09 by one year to now be effective for fiscal years, and interim reporting periods within those years, beginning after December 15, 2017. Early adoption of the standard is permitted but not before the original effective date of December 15, 2016. The ASU may be adopted using a full retrospective approach or reporting the cumulative effect as of the date of adoption. In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which is intended to improve the operability and understandability of the implementation guidance on principle versus agent considerations. Additionally, in April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, which provides further guidance on identifying performance obligations and improves the operability and understandability of the licensing implementation guidance. Both ASU No. 2016-08 and 2016-10 have the same effective date and transition requirements as ASU No. 2014-09. We are currently evaluating the impact of adopting this guidance. In July 2015, the FASB issued ASU No. 2015-11, Inventory: Simplifying the Measurement of Inventory. ASU 2015-11 changes the criteria for measuring inventory within the scope of the ASU. Inventory will now be measured at the lower of cost and net realizable value, while the concept of market value will be eliminated. The ASU defines net realizable value as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. ASU 2015-11 is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years, with earlier adoption permitted. The prospective adoption of the ASU is required. The adoption of this guidance is not expected to have a material effect on our financial condition, results of operations or cash flows. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The amended guidance is intended 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 adoption of this guidance is expected to result in a significant portion of our operating leases, where we are the lessee, to be recognized on our Consolidated Balance Sheets. The guidance requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years with earlier adoption permitted. We are currently evaluating the impact of adopting this guidance. In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The amended guidance is intended to simplify several aspects of accounting for share-based payment award transactions, including income tax consequences, classification of awards as either equity or liabilities and classification in the statement of cash flows. The amendments related to the timing of when excess tax benefits are recognized, minimum statutory withholding requirements, forfeitures, and intrinsic value are required to be applied using a modified retrospective transition method by means of a cumulative-effect adjustment to equity as of the beginning of the period in which the guidance is adopted. The amendments requiring recognition of excess tax benefits and tax deficiencies in the income statement and the practical expedient for estimating expected term is required to be applied prospectively. The guidance related to the presentation of employee taxes paid in the statement of cash flows is required to be applied retrospectively and amendments related to the presentation of excess tax benefits in the cash flows statement of cash flows may be adopted either prospectively or retrospectively. ASU No. 2016-09 is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years with earlier adoption permitted. We are currently evaluating the impact of adopting this guidance.
