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 and lottery industries. Our portfolio includes gaming machines and game content, instant and draw‑based lottery games, server‑based gaming and lottery systems, casino-management systems, table game products and services, sports betting technology, loyalty and rewards programs and interactive gaming and lottery content and services. We also gain access to technologies and pursue global expansion through strategic acquisitions and equity investments. As a result of our recent acquisitions of Bally and WMS, we have significantly expanded our global gaming business. 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 ("$") 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 consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our 2014 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 2014 Annual Report on Form 10-K. Recently Issued Accounting Guidance In January 2014, the FASB issued ASU 2014-05, Service Concession Arrangements (Topic 853), a consensus of the FASB Emerging Issues Task Force, which specified that an operating entity should not account for a service concession arrangement within the scope of the update as a lease in accordance with ASC 840, Leases. The guidance was effective for fiscal years beginning after December 15, 2014. The adoption of ASU 2014-05 did not have an impact on our financial condition, results of operations or cash flows. In April 2014, the FASB issued ASU 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. ASU 2014-08 changes the criteria for reporting discontinued operations and modifies related disclosure requirements. The new guidance is effective on a prospective basis for fiscal years beginning after December 15, 2014, and interim periods thereafter. The adoption of ASU 2014-08 did not have a material effect on our financial condition, results of operations or cash flows. In May 2014, the FASB issued ASU No. 2014-09, 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." ASU 2014-09 is effective for fiscal years, and interim reporting periods within those years, beginning after December 15, 2016 (early adoption is not permitted). We are currently evaluating the impact of adopting ASU 2014-09. In June 2014, the FASB issued ASU No. 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. ASU 2014-12 requires that a performance target that affects vesting and could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in ASC 718, Compensation—Stock Compensation, as it relates to such awards. ASU 2014-12 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2015 with early adoption permitted using either of two methods: (i) prospective to all awards granted or modified after the effective date; or (ii) retrospective to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter, with the cumulative effect of applying ASU 2014-12 as an adjustment to the opening retained earnings balance as of the beginning of the earliest annual period presented in the financial statements. We do not expect ASU 2014-12 to have a material effect on our financial condition, results of operations or cash flows. In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements - Going Concern: Disclosure of Uncertainties About an Entity's Ability to Continue as a Going Concern. ASU 2014-15 requires management to perform interim and annual assessments as to whether there are conditions or events that raise substantial doubt about the entity's ability to continue as a going concern within one year of the date the financial statements are issued and to provide related disclosures, if required. ASU 2014-15 is effective for annual periods ending after December 15, 2016 and for annual periods and interim periods thereafter. Early adoption is permitted. We do not expect ASU 2014-15 to have a material effect on our financial condition, results of operations or cash flows. In January 2015, the FASB issued ASU No. 2015-01, Income Statement-Extraordinary and Unusual Items: Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items. ASU 2015-01 eliminates from GAAP the concept of extraordinary items. The presentation and disclosure guidance for items that are unusual in nature or occur infrequently will be retained and will be expanded to include items that were previously classified as extraordinary. ASU 2015-01 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015 with early adoption permitted using either a prospective or retrospective method. We do not expect ASU 2015-01 to have a material effect on our financial condition, results of operations or cash flows. In April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. ASU 2015-03 intends to simplify the presentation of debt issuance costs by requiring that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this ASU. ASU 2015-03 is effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. We do not expect ASU 2015-03 to have a material effect on our financial condition, results of operations or cash flows.
