Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies The consolidated financial statements and accompanying notes, which are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”), reflect the application of significant accounting policies described below and elsewhere in the notes to the consolidated financial statements. Principles of Consolidation The accompanying consolidated financial statements include the accounts of International Game Technology PLC and its consolidated subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The consolidated financial statements are presented in U.S. dollars and all amounts are rounded to the nearest thousand (except share and per share data) unless otherwise indicated. Investments in other entities that the Company has the ability to control, through a majority voting interest or otherwise, or with respect to which the Company is the primary beneficiary, are consolidated. Earnings or losses attributable to any non-controlling interests or redeemable non-controlling interests in a subsidiary are included in net income (loss) in the consolidated statements of operations. Any investments in affiliates over which the Company has the ability to exert significant influence, but do not control and with respect to which the Company is not the primary beneficiary, are accounted for using the equity method of accounting. Investments in affiliates for which the Company has no ability to exert significant influence are accounted for using the cost method of accounting. A Variable Interest Entity ("VIE") is an entity that by design possesses the following characteristics: • The equity investment at risk is not sufficient for the entity to finance its activities without additional subordinated financial support; or • As a group, the holders of equity investment at risk do not possess: 1. The power, through voting rights or similar rights, to direct the activities that most significantly impact the entity's economic performance; or 2. The obligation to absorb expected losses or the right to receive the expected residual returns of the entity; or 3. Symmetry between voting rights and economic interests and where substantially all of the entity's activities either involve or are conducted on behalf of an investor with disproportionately fewer voting rights (i.e., structures with non-substantive voting rights). In determining whether the Company is the primary beneficiary of a VIE for financial reporting purposes, the Company considers whether it has the power to direct the activities of the VIE that most significantly impact the economic performance of the VIE and whether it has the obligation to absorb losses or the right to receive returns that would be significant to the VIE. The Company consolidates VIEs when it is the primary beneficiary. Use of Estimates The preparation of financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, the reported amounts of revenues, costs and expenses during the reporting period and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. Significant estimates and judgments relied upon by the Company in preparing these financial statements include the timing of revenue recognition; the fair value assigned to acquired assets and assumed and contingent liabilities, associated with business combinations; expensing or capitalizing research and development costs for software development; the funding amount for Wide Area Progressive jackpot payments; minimum profit level guarantees; the assessment of legal and other contingencies; the determination of whether the Company is the primary beneficiary of a VIE, the determination of the probability of redemption of redeemable non-controlling interests, and the amount of the provision for income taxes and the valuation of deferred taxes and intangible assets, including goodwill. Foreign Currency Translation The functional currency of the Company's subsidiaries located outside of the United States are determined in accordance with authoritative guidance issued by the Financial Accounting Standards Board, or FASB. Assets and liabilities for these subsidiaries are translated at exchange rates in effect at the balance sheet date. Income and expense accounts for these subsidiaries are translated at the average exchange rates for the periods. Resulting translation adjustments are recorded as a component of accumulated other comprehensive income (loss) within shareholders’ equity. The Company records gains and losses from currency transactions denominated in currencies other than the functional currency in its consolidated statement of operations. Local currency transactions of subsidiaries located outside of the United States where the U.S. dollar is the functional currency are remeasured into U.S. dollars using current rates of exchange for monetary assets and liabilities and historical rates of exchange for non-monetary assets and liabilities. Gains and losses from remeasurement of monetary assets and liabilities are recorded in the consolidated statement of operations. Acquisitions The Company accounts for acquired businesses using the acquisition method of accounting, which requires that the assets acquired, liabilities assumed, contractual contingencies and contingent consideration be recorded at the date of acquisition at their respective fair values. Goodwill represents the excess of the purchase price, including the fair value of any contingent consideration, over the fair value of the net assets acquired. It further requires (1) acquisition related costs to be recognized separately from the acquisition and expensed as incurred, (2) most restructuring costs to be expensed in periods subsequent to the acquisition date and (3) changes in accounting for deferred tax asset valuation allowances and acquired income tax uncertainties after the measurement period to be reflected in the provision for income taxes. The operating results of acquisitions are included in the consolidated financial statements from the date control is obtained. Acquisition and disposition related costs are included in the consolidated statement of operations within “Transaction expense, net”. Transaction expense, net is composed of transaction costs on significant business combinations and significant gains and losses incurred on disposals of group entities or businesses. The fair value of identifiable intangible assets is based on significant judgments made by the Company, including the selection of the appropriate valuation methodologies and the determination of the economic lives of the assets acquired. These estimates and assumptions are based on historical and industry experience, information obtained from management of the acquired business, and also include, but are not limited to, future expected cash flows earned from the identified intangible assets and discount rates applied in determining the present value of those cash flows. Unanticipated events and circumstances may occur that could affect the accuracy or validity of such assumptions, estimates or actual results. Acquired identifiable intangible assets are amortized using the straight-line method over their estimated economic lives. Amortization of acquired software-related intangibles is included in cost of services and cost of product sales and amortization of other acquired intangible assets is included in selling, general and administrative expenses in the consolidated statement of operations. Goodwill, Intangible Assets and Long-Lived Assets Goodwill is tested for impairment annually at the reporting unit level, which is one level below or the same level as an operating segment. The Company has five reporting units as follows: • North America Gaming and Interactive; • DoubleDown; • North America Lottery; • International; and • Italy. When testing goodwill for impairment, the Company first performs a qualitative assessment to determine whether it is necessary to perform step one of a two-step annual goodwill impairment test for each reporting unit. The first step of the two-step process is to identify whether a potential impairment exists by comparing the estimated fair values of the reporting units with their respective book values, including goodwill. If the estimated fair value of the reporting unit exceeds book value, goodwill is not considered impaired, and no additional steps are necessary. If the fair value of the reporting unit is less than book value, then the second step is performed to determine if goodwill is impaired and to measure the amount of impairment loss, if any. The amount of the impairment loss is the excess of the carrying amount of the goodwill over its estimated fair value. The estimate of fair value of goodwill is primarily based on an estimate of the discounted cash flows expected to result from that reporting unit, but may require valuations of certain internally generated and unrecognized intangible assets such as software, technology, patents and trademarks. If the carrying amount of goodwill exceeds the estimated fair value of that goodwill, an impairment loss is recognized in an amount equal to the excess. The Company also evaluates indefinite-lived intangible assets for impairment annually and whenever events or changes in circumstances indicate impairment may exist. The Company first performs a qualitative assessment to determine whether it is more likely than not that the fair value of indefinite-lived intangible assets are less than their carrying amount and whether the quantitative analysis is necessary. The quantitative analysis compares the fair value of indefinite-lived intangible assets to their carrying amount and an impairment loss is recognized when the carrying amount exceeds the fair value. The process of evaluating the potential impairment related to goodwill and indefinite-lived intangible assets is highly subjective and requires the application of significant judgment. If an event occurs that would cause revisions to the estimates and assumptions used in analyzing the value of goodwill and other intangible assets with indefinite lives, the revision could result in a non-cash impairment loss that could have a material impact on the Company’s financial results. The Company’s annual review of goodwill and indefinite-lived intangible assets for impairment is performed as of November 1 each year. The 2016 review resulted in impairment losses of $30.0 million in the DoubleDown reporting unit for certain indefinite lived trademarks relating to the forecasted slowing of growth in the social gaming market. The 2015 review resulted in impairment losses of $9.7 million in the International segment for certain indefinite lived trademarks. The Company evaluates long-lived assets, including identifiable intangible assets and other assets, for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. Events or changes in circumstances that could result in an impairment review include, but are not limited to, significant underperformance relative to historical or projected future operating results, significant changes in the manner of use of the acquired assets or the overall business strategy and significant negative industry or economic trends. Impairment is recognized when the asset is not recoverable and the carrying amount of an asset exceeds its fair value as calculated on a discounted cash flow basis. If an event occurs necessitating revised estimates and assumptions previously used in analyzing the value of property and equipment or finite-lived intangibles and other assets, that revision could result in a non-cash impairment loss that could have a material impact on the Company’s financial results. The Company recorded impairment losses related to long-lived assets of $7.7 million , $2.8 million and $2.6 million in 2016 , 2015 and 2014 , respectively. Fair Value of Financial Instruments The Company applies the authoritative guidance on fair value measurements for financial assets and liabilities that are measured at fair value on a recurring basis, as well as those financial assets and liabilities that are not measured at fair value but for which fair value is disclosed. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (exit price), in the principal or most advantageous market, in an orderly transaction between market participants, on the measurement date. The guidance establishes a three-tiered fair value hierarchy that prioritizes inputs to valuation techniques used in fair value calculations. The three levels of inputs are defined as follows: Level 1: Unadjusted quoted prices for identical assets or liabilities in active markets accessible by the Company at the measurement date. Level 2: Inputs that are observable in the marketplace other than those inputs classified as Level 1, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3: Inputs that are unobservable in the marketplace and significant to the valuation. Valuation methods and assumptions used to estimate fair value, when quoted market prices are not available, are subject to judgments and changes in these factors can materially affect fair value estimates. For financial assets and financial liabilities that are recognized at fair value on a recurring basis, the Company determines whether transfers have occurred between levels in the hierarchy by re-assessing categorization (based on the lowest level input that is significant to the fair value measurement as a whole) at the end of each reporting period. The carrying amounts reported in the consolidated balance sheets for cash and cash equivalents, restricted cash and investments, accounts receivable, other current assets, accounts payable, and other current liabilities approximate fair value due to relatively short periods to maturity. Derivative Instruments The Company uses derivative instruments to manage the impact of foreign currency exchange and interest rate changes on earnings and cash flows. The Company does not enter into derivative instruments for speculative purposes. It is the Company’s policy to negotiate the terms of the derivative to match the terms of the hedged item to maximize hedge effectiveness. Derivative instruments are recognized as either assets or liabilities on the balance sheet at fair value. Accounting for changes in the fair value of the derivative depends on the nature of the hedge and the hedge effectiveness as described further below. Derivative gains and losses are reported as operating activities within the consolidated statement of cash flows. The Company uses foreign currency forward and option contracts to offset its exposure to the change in value of certain foreign currency denominated monetary assets and liabilities. Since these derivatives hedge existing exposures that are denominated in foreign currencies, the contracts do not qualify for hedge accounting. Accordingly, these outstanding non-designated derivatives are recognized on the consolidated balance sheet at fair value with the changes in fair value recorded in foreign exchange gain (loss), net, in the consolidated statement of operations. These derivative contracts mature in less than 1 year . The Company also uses foreign currency forward and option contracts to hedge its exposure on certain forecasted foreign currency revenue and expense transactions. The terms of the contracts are typically matched with the forecasted foreign currency transactions to be derived from operations up to a period of 12 months. These derivatives are designated as cash flow hedges. All outstanding cash flow hedges are recognized on the consolidated balance sheets at fair value with the effective portion of the gain or loss recorded in accumulated other comprehensive income (loss). When the underlying hedged transaction is recognized, the effective portion of the gain or loss on the derivative instrument is reclassified from accumulated other comprehensive income (loss) to the consolidated statement of operations, in the related revenue or expense caption, as appropriate. Any ineffectiveness is recognized immediately into earnings. There was no ineffectiveness for any period presented. The Company uses interest rate derivative instruments designated as fair value hedges to manage the exposure to interest rate movements and to reduce borrowing costs by converting fixed-rate debt into floating-rate debt. Under these agreements, the Company agrees to exchange, at specified intervals, the difference between fixed and floating interest amounts calculated by reference to agreed-upon notional principal amounts. Changes in the fair value of the derivative instrument are recorded in other income or expense and are offset by changes in the fair value of the underlying debt instrument due to changes in the benchmark interest rate. The cash flows from these contracts are reported as operating activities in the consolidated statement of cash flows. The gains (losses) from terminated interest rate swap agreements are recorded in long-term debt, increasing (decreasing) the outstanding balances of the debt, and amortized as a reduction (addition) of interest expense over the remaining life of the related debt. The cash flows from the termination of the interest rate swap agreements are reported as financing activities in the consolidated statement of cash flows. Debt Issuance Costs and Premiums/Discounts The Company accounts for incremental costs directly attributable to realizing the proceeds of a debt issuance and the difference between the net proceeds received upon debt issuance and the amount payable at maturity as adjustments to the carrying amount of the debt on its consolidated balance sheets. These adjustments are amortized to interest expense using the effective interest method over the estimated term of the debt, typically the contractual term. Revenue Recognition The Company has two categories of revenue: Service revenue and Product sales. Service revenue is derived from the following sources: • Operating contracts predominantly related to Italian contracts and certain U.S. contracts; • Gaming operations arrangements where the Company provides customers with proprietary gaming equipment, systems, content licensing, and services; • Facilities Management Contracts (Hosting arrangements); • Interactive contracts; and • Post-contract customer support (“PCS”). Product sales are derived from the following sources: • Sale of lottery terminals and gaming machines, including game content; and • Sale of lottery and gaming systems, including the licensing of proprietary software, and including implementation services. Revenue is recognized when all of the following conditions are met: (i) Persuasive evidence of an arrangement exists; (ii) Delivery has occurred; (iii) The fee is fixed or determinable; and (iv) Collectability is probable. Revenues are reported net of amortization of upfront payments to customers, incentives, rebates, and discounts. Sales taxes, gaming taxes and other taxes of a similar nature are presented on a net basis (excluded from revenue). Amounts billed prior to completing the earnings process are deferred until revenue recognition criteria is met. Service revenue Service revenue is derived from the following types of arrangements: Operating contracts Certain of the Company’s revenue, primarily revenue from the Italy segment and to a lesser extent the North America Lottery segment, is derived from operating contracts. Under operating contracts, the Company manages all the activities along the lottery value chain including collecting wagers, paying out prizes, managing all accounting and other back-office functions, running advertising and promotions, operating data transmission networks and processing centers, training staff, providing retailers with assistance and supplying materials for the game. In Italian arrangements where the Company is performing services on behalf of the government and the government is considered the Company’s customer, revenue is recognized net of prize payments, taxes, retailer commissions and remittances to state authorities, because the Company is acting as an agent to the authorities. In arrangements where the Company’s customers are the end players and/or retailers, the Company records revenue net of prizes and taxes only, and records the retailer commissions as a cost of service, because the Company is acting as the principal. The Company also provides sports pools and sports betting services. Under sports pools arrangements, the Company manages the sports pool where the sports pool prizes are divided among those players who select the correct outcome. There are no odds involved in sports pools and each winner’s payoff depends on the number of players and the size of the pool. Under sports pools arrangements, the Company collects the wagers, pays prizes, pays a percentage fee to retailers, withholds its fee, and remits the balance to the respective regulatory agency. The Company assumes no risk associated with sports pool wagering. The Company records revenue net of prize payouts, gaming taxes, retailer commissions and remittances to state authorities, because the Company is acting as an agent to the authorities. In sports betting contracts, the Company establishes and assumes the risks related to the odds. Under fixed odds betting, the potential payout is fixed at the time bets are placed and the Company bears the risk of odds setting. The Company is responsible for collecting the wagers, paying prizes, and paying fees to retailers. The Company retains the remaining cash as profits. Under these arrangements, the Company records revenue net, calculated as total wagers less the estimated payout for prizes, because the betting contract is considered a derivative and is required to be recorded at fair value. Taxes are recorded as contra revenue and retailer commissions are shown as expenses. Fees earned under operating contracts are recognized as revenue in the period earned and are classified as service revenue in the consolidated statement of operations when all of the criteria outlined above are met. Under operating contracts, the Company is generally required to pay upfront license fees. When such upfront payments are made to the Company’s customers, the payment is recorded as a non-current asset and amortized as a reduction of service revenue over the license term. Gaming Operations Gaming operations revenues are generated by providing customers with proprietary land-based gaming equipment, systems, content licensing, and services under a variety of recurring revenue arrangements, including a percentage of coin-in (amounts wagered), a percentage of net win, or a fixed daily/monthly fee. Included in gaming operations are Wide Area Progressive (“WAP”) systems. WAP systems consist of linked slot machines located in multiple casino properties, connected to a central computer system. WAP games differ from all other games in that a Company-sponsored progressive jackpot increases with every wager until a player wins the top award combination. Casinos with WAP machines pay a percentage of the coin-in (amounts wagered) for services related to the design, assembly, installation, operation, maintenance, and marketing of the WAP systems, as well as funding and administration of Company-sponsored progressive jackpots. Fees earned under gaming operations are recognized as revenue in the period earned and are classified as service revenue in the consolidated statement of operations when all of the criteria outlined above are met. Facilities management contracts Under facilities management contracts, the Company constructs, installs, operates and retains ownership of the online system. These contracts, principally in the North America Lottery segment, generally provide for a variable amount of monthly or weekly service fees paid to the Company directly from the customer based on a percentage of sales. Fees earned under facilities management contracts are recognized as revenue in the period earned, throughout the service period, and are classified as service revenue in the consolidated statement of operations when all of the criteria outlined above are met. Interactive Contracts Interactive revenues are principally generated from online social gaming and online real-money products and services (“IGTi”). Social gaming revenues are generated from the sale of virtual casino chips to players in the online DoubleDown Casino that can be used for additional play or game enhancements. Revenues from player purchases are recognized ratably over the estimated average service period in which the chips are consumed based on historical data analysis. Because DoubleDown is the principal, responsible for substantially all aspects of the casino services and sale of virtual goods to the player, revenues are recorded on a gross basis. Payment processing fees paid to Facebook, Apple and Google on a revenue participation basis are recorded within cost of services. IGTi revenues are generated from online real-money gaming solutions offerings, which encompass gaming systems infrastructure, applications, content licensing, and back office operational support services, including WAP jackpot funding and administration. IGTi solutions are generally provided under revenue sharing arrangements based on a percentage of net win similar to gaming operations discussed above. Post-Contract Customer Support (PCS) Product sales contracts generally include PCS, which includes telephone support, software maintenance, software support, professional services, and in some scenarios the right to receive unspecified upgrades/enhancements on a when-and-if-available basis. Fees earned under PCS contracts are generally recognized as revenue in the period earned (i.e., over the support period) and are classified as service revenue in the consolidated statement of operations when all of the criteria outlined above are met. Product Sales Product sales are derived from the following types of arrangements: Sale of Lottery Terminals and Sale of Gaming Machines, including Game Content These arrangements include the sale of gaming machines including game content, non-machine gaming related equipment, licensing and royalty fees, and component parts (including game themes and electronics conversion kits). The Company’s credit terms are predominantly short-term in nature. The Company also grants extended payment terms under contracts where the sale is secured by the related equipment sold. Revenue from the sale of lottery terminals and gaming machines is recognized based upon the contractual terms of each arrangement, but predominantly upon delivery or acceptance. If the sale of lottery terminals and gaming machines include multiple elements, these arrangements are accounted for under Multiple Element Accounting, discussed below. System Sales (Lottery and Gaming) System Sale arrangements typically include multiple elements, where the Company constructs, sells, delivers and installs a turnkey system (inclusive of point of sale terminals, if applicable) or delivers equipment and licenses the computer software for a fixed price, and the customer subsequently operates the system. System sale arrangements generally include customer acceptance provisions and general rights to terminate the contract if the Company is in breach of the contract. Such arrangements include non-software elements, software, professional services, and PCS in the form of maintenance and software support arrangements. Amounts due to the Company and costs incurred by the Company in implementing the system prior to customer acceptance are deferred. Revenue attributable to the system is classified as product sales in the consolidated statement of operations and is recognized upon customer acceptance as long as there are no substantial doubts regarding collectability. Revenues attributable to PCS provided subsequent to customer acceptance are classified as service revenue in the consolidated statement of operations in the period earned. Multiple Element Arrangements The Company uses multiple element guidance for both service arrangements and product sale arrangements. In some scenarios, all deliverables are considered one unit of accounting (i.e., facilities management contracts where the Company provides software as a service), while other arrangements contain multiple elements that can be separated into distinct deliverables. When arrangements contain multiple elements, including software and non-software components, the Company allocates revenue to each category based on a selling price hierarchy. Allocation of revenue to software and non-software components is based on either vendor-specific objective evidence ("VSOE") if available, third-party evidence ("TPE") if VSOE is not available, or best estimate of selling price ("BESP") if neither VSOE nor TPE is available. • VSOE of selling price is based on the net price charged when the element is sold separately. In determining VSOE, the Company requires that a substantial majority of the selling prices fall within a reasonable range based on historical discounting trends for specific products and services. VSOE for post-contract support and professional service hours may also be determined based on renewal rates, if available, provided that the renewal rates are substantive. • TPE of selling price is established by evaluating largely interchangeable competitor products or services in stand-alone sales to similar customers. However, as the Company’s products contain a significant element of proprietary technology and the Company’s solutions offer different features and functionality, the comparable pricing of third-party products with similar functionality typically cannot be obtained. • BESP is established considering multiple factors including, but not limited to, market conditions, competitive landscape, internal costs, and gross profit objectives. In some scenarios, contractual pricing may serve as the best estimate given the variability among jurisdictions and customers, while in other scenarios cost for each deliverable plus reasonable margin is used as management’s best estimate. In scenarios where the Company’s products include hardware containing required software that function together to provide the essential functionality of the product, the Company considers both the hardware and required software as “non-software deliverables” and has therefore concluded that such arrangements are not subject to the industry-specific software revenue recognition guidance. The Company recognizes revenue for these arrangements based on Accounting Standards Codification ("ASC") 605, Revenue Recognition , and allocates the arrangement consideration based on the relative selling price of the deliverables. In scenarios where the Company’s products include hardware where the software is not considered essential to the functionality of the hardware, the hardware revenue is recognized based on when the revenue recognition criteria is met (i.e., shipment, delivery and/or acceptance) and the software revenue is recognized under the software revenue recognition guidance provided under ASC 985, Software . If there are multiple deliverables within the software and non-software categories, revenue is first allocated between the software pool of deliverables and the non-software pool of deliverables on a relative fair value basis. Thereafter, revenue for each pool is further allocated as follows: • Non-software components: Revenue is further allocated to each separate unit of accounting using the relative selling prices of each deliverable in the priority order described above. However, revenue is only recognized if the unit of accounting has stand-alone value. A deliverable is considered to have stand-alone value if (a) it has value to the customer on stand-alone basis, and (b) if a general right of return exists relative to the delivered item, delivery or performance of the undelivered item is considered probable and substantially in the Company’s control. •

Business Combinations [Abstract]
Acquisitions	Acquisitions The acquisition of IGT was completed on April 7, 2015 (the “Acquisition Date”). IGT is a global gaming company specializing in the design, development, manufacture and marketing of casino-style gaming equipment, systems technology and game content across multiple platforms — land-based, online real money and social gaming. The acquisition of IGT established the Company as the world’s leading end-to-end gaming company, uniquely positioned to capitalize on opportunities in global gaming markets. The Company combines best-in-class content, operator capabilities, and interactive solutions, joining IGT’s leading game library and manufacturing and operating capabilities with GTECH’s gaming operations, lottery technology and services. Total acquisition consideration of $4.545 billion consisted of $3.616 billion cash consideration and $0.929 billion equity consideration. Consistent with the terms of the transaction, equity consideration was determined based on the average of the volume-weighted average prices of GTECH common shares on the Italian Stock Exchange, converted to the U.S. dollar equivalent, for 10 randomly selected days within the period of 20 consecutive trading days ending on the second full trading day prior to the Acquisition Date. Under the terms of the transaction, IGT shareholders received 45.3 million common shares of the Parent, and IGT employees received 1.4 million restricted stock units. The Company utilized the closing stock price immediately prior to the merger and the number of shares issued to determine the fair value of the consideration. Equity consideration included the fair value of shares vested and outstanding immediately prior to the Acquisition Date of $917.3 million and the portion of outstanding restricted stock units deemed to have been earned as of the Acquisition Date of $11.6 million . The portion of outstanding restricted stock units deemed not to have been earned as of the Acquisition Date of $16.2 million were expensed over the remaining future vesting period. The transaction was accounted for as a business combination using the acquisition method of accounting. This method requires that the assets acquired and liabilities assumed be recognized at their fair values as of the Acquisition Date. In 2016, adjustments were made to finalize the fair value of tax assets and liabilities. The following table summarizes the final allocation of the consideration to the fair values of the assets acquired and liabilities assumed at the Acquisition Date. ($ thousands) Purchase Price Allocation: Cash consideration 3,616,410 Equity consideration 928,884 Total purchase price 4,545,294 Fair value of assets acquired and liabilities assumed: Cash and cash equivalents 374,995 Restricted cash 56,656 Trade and other receivables 237,488 Inventories 95,562 Other current assets 361,003 Systems, equipment and other assets related to contracts 126,524 Property, plant and equipment 336,044 Intangible assets 2,960,000 Other non-current assets 628,620 Deferred income tax assets 246,953 Accounts payable (75,814 ) Other current liabilities (379,968 ) Long-term debt, less current portion (1,937,942 ) Deferred income tax liabilities (1,069,833 ) Other non-current liabilities (360,335 ) 1,599,953 Goodwill 2,945,341 Goodwill recognized as a result of the acquisition is not deductible for tax purposes.

The Company incurred $1.7 million , $49.4 million and $44.0 million of legal, accounting and other professional fees and expenses in 2016 , 2015 and 2014 , respectively, related to the IGT acquisition. These expenses are included in the consolidated statement of operations in the line item entitled “Transaction expense, net.” The Company’s consolidated financial statements for the year ended December 31, 2015 include IGT’s results of operations from April 7, 2015 through December 31, 2015. Revenue and operating loss attributable to IGT during this period total $1.346 billion and $45.4 million , respectively. The $45.4 million operating loss includes $276.0 million of acquired intangible assets amortization, which are a direct result of the IGT acquisition. The following unaudited, pro forma financial information presents the combined results of operations as if the acquisition had been completed on January 1, 2014, the beginning of the comparable prior annual period. This pro forma information is provided for illustrative purposes only and is not necessarily indicative of the results that would have been obtained if the acquisition had occurred on the date assumed or that may occur in the future, and does not reflect synergies, integration costs, or other such costs or savings.

Foreign currency forward contracts were calculated by reference to current forward exchange rates for contracts with similar maturity profiles. Foreign currency forward contracts are presented as current assets and current liabilities in the consolidated balance sheet. Interest rate swaps were calculated by discounting future cash flows using LIBOR rates with an appropriate adjustment for credit risk. Interest rate swaps are presented as current assets and non-current liabilities in the consolidated balance sheet. Jackpot investments were valued using quoted market prices. Jackpot investments are presented as other current and non-current assets in the consolidated balance sheet. Available-for-sale investments were valued using quoted market prices. Available-for-sale investments are presented as other non-current assets in the consolidated balance sheet. Financial assets and liabilities not carried at fair value The following tables represent the fair value hierarchy for financial assets and liabilities not measured at fair value at December 31, 2016 and 2015 : December 31, 2016 ($ thousands) Carrying Fair Value Level 1 Level 2 Level 3 Total Unrealized Customer financing receivables, net 163,735 165,241 — — 165,241 165,241 1,506 Available-for-sale investments 14,838 14,838 — — 14,838 14,838 — Jackpot liabilities 299,042 291,026 — — 291,026 291,026 8,016 Debt 7,872,285 8,415,890 — 8,415,890 — 8,415,890 (543,605 ) December 31, 2015 ($ thousands) Carrying Fair Value Level 1 Level 2 Level 3 Total Unrealized Customer financing receivables, net 199,845 199,845 — — 199,845 199,845 — Available-for-sale investments 13,232 13,232 — — 13,232 13,232 — Jackpot liabilities 337,243 329,923 — — 329,923 329,923 7,320 Debt 8,343,368 8,176,986 6,450,306 1,726,680 — 8,176,986 166,382 Valuation Techniques and Balance Sheet Presentation Customer financing receivables, net are recorded and valued based on expected payments and market interest rates (ranging from 4.30% to 13.10% ) relative to the credit risk of each customer region. Credit risk is determined on a number of factors, including customer size, type, financial condition, historical collection experience, account aging, and credit ratings derived from credit reporting agencies and other industry trade reports. Contracts are typically secured by the underlying assets sold and notes are secured by the developed property and/or other assets. The higher risk rate categories include most of the Company’s development financing loans in new markets and customers in regions with a history of currency or economic instability, such as Latin America. Customer financing receivables, net are presented as other current and non-current assets in the consolidated balance sheet. Available-for-sale investments are carried at cost (which approximates fair value) and are presented as other non-current assets in the consolidated balance sheet. Jackpot liabilities were primarily valued using discounted cash flows, incorporating expected future payment timing, estimated funding rates based on the treasury yield curve, and nonperformance credit risk. Expected annuity payments over one to 25 years (average 10 years ) were discounted using the 10 -year treasury yield curve rate ( 2.45% ) for the estimated funding rate and the 10 -year credit default swap rate ( 2.13% ) for nonperformance risk. The present value (carrying value) of the expected lump sum payments were discounted using the 1 -year treasury yield curve rate ( 0.85% ) with the 1 -year credit default swap rate ( 0.18% ) for the current amounts and the 2 -year treasury yield curve rate ( 1.20% ) with the 2 -year credit default swap rate ( 0.35% ) for non-current amounts. Significant increases (decreases) in any of these inputs in isolation would result in a lower (higher) fair value measurement. Generally, changes in the estimated funding rates do not correlate with changes in non-performance credit risk. Jackpot liabilities are presented as other current and non-current liabilities in the consolidated balance sheet. Debt is predominantly level 1 and valued using quoted market prices or dealer quotes for the identical financial instrument when traded as an asset in an active market. Revolving facilities and term loans with variable interest rates are level 2 and valued using current interest rates, excluding the effect of debt issuance costs. Carrying values in the table exclude swap adjustments.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives The Company uses selected derivative hedging instruments, including principally foreign currency forward contracts and interest rate swaps, for the purposes of managing currency risks and interest rate risk arising from its operations and sources of financing. Cash flow hedges The gross notional amount of foreign currency forward contracts, designated as cash flow hedges, outstanding at December 31, 2016 and 2015 was $120.9 million and $4.7 million , respectively. Net realized and unrealized gains and losses from foreign currency cash flow hedges included in other comprehensive income at December 31, 2016 and 2015 was $ 8.1 million and $ (0.5) million . The amount retained in other comprehensive income at December 31, 2016 is expected to mature and affect the consolidated statement of operations in 2017 . Fair value hedges In September 2015, the Company executed $625 million notional amount of interest rate swaps (“swaps”) that effectively convert $625 million of the 6.250% Senior Secured Notes due 2022 from fixed interest rate debt to variable rate debt. Under the terms of these swaps, the Company is required to make variable rate interest payments based on six-month LIBOR plus a fixed spread, collectively ranging between 5.65% and 5.77% at December 31, 2016 , and will receive fixed rate interest payments from its counterparties based on a fixed rate of 6.25% . The LIBOR rate resets semiannually on February 15 and August 15. Settlement of the net amount of interest receivable or payable under the swaps occurs semiannually on February 15 and August 15. The swaps terminate in February 2022. The Company held interest rate swaps exchanging fixed rate interest payments for variable rate interest payments (described below) that were designated fair value hedges against changes in the fair value portion of the respective notes. Net amounts receivable or payable under the swaps settled semiannually on June 15 and December 15 of each year. Swaps related to the 7.500% Senior Secured Notes due 2019 included $250 million notional amounts with a variable rate based on one-month LIBOR plus 342 bps, and $250 million notional amounts with a variable rate based on six-month LIBOR plus 409 bps. Both swaps carried a termination date of June 15, 2019. Swaps related to the 5.500% Senior Secured Notes due 2020 totaled $300 million notional amount with a variable rate based on the six-month LIBOR plus 186 bps with a termination date of June 15, 2020. In conjunction with the tender in April 2015 of $175.9 million principal of 5.500% Senior Secured Notes due 2020, $175.9 million notional amount of related interest rate swaps were canceled. The Company received cash proceeds of $13.0 million from the swap counterparties upon settlement in May 2015. The remaining $124.1 million notional amount of interest rate swaps equaled the remaining outstanding principal of the 5.500% Senior Secured Notes due 2020. In September 2015, all remaining swaps related to the 7.500% Senior Secured Notes due 2019 and 5.500% Senior Secured Notes due 2020 with a collective notional amount of $624 million were canceled. The Company received cash proceeds of $59.0 million from the swap counterparties, which reduced the swap fair value adjustment asset and interest receivable to zero. However, in accordance with hedge accounting requirements, a swap fair value adjustment to debt remained to be amortized as a reduction to interest expense over the remaining debt life. The balance of the swap fair value adjustment was $0.9 million and $1.3 million at December 31, 2016 and December 31, 2015 , respectively. At December 31, 2014, the Company did not hold any fair value hedges. The €150 million ( $182.1 million at the December 31, 2014 exchange rate) notional amount of swaps, which were designated as hedges of fixed interest rates on the 5.375% Senior Notes due 2016 were settled in December 2014, in connection with the redemption of those notes, resulting in a $10.1 million gain. Derivatives not designated as hedging instruments The notional amount of foreign currency forward contracts, not designated as hedging instruments, outstanding at December 31, 2016 and 2015 was $364.5 million and $352.6 million , respectively.

The Parent is tax resident in the United Kingdom. A reconciliation of the provision for income taxes, with the amount computed by applying the weighted average rate of the United Kingdom statutory main corporation tax rates enacted in each of the Parent’s calendar year reporting periods ( 20.00% in 2016 , 20.25% in 2015 and 21.50% in 2014 ) to income (loss) before the provision for income taxes is as follows: For the year ended December 31, ($ thousands) 2016 2015 2014 Income (loss) before provision for income taxes 323,413 (17,031 ) 340,217 United Kingdom statutory tax rate 20.00 % 20.25 % 21.50 % Theoretical tax expense (benefit) 64,682 (3,449 ) 73,147 IRAP and other local taxes 36,754 29,697 49,806 Italian tax litigation settlement 15,256 — 19,934 Tax cost of dividend 4,619 12,888 3,903 Foreign losses with no tax benefit 3,610 7,495 12,255 Foreign tax expense, net of federal benefit 3,457 9,003 10,765 Nondeductible expenses 2,659 30,244 9,052 Italian reorganization tax — 13,405 35,989 Non-controlling interest (3,605 ) 8,565 5,015 Research and development tax credit (4,980 ) (4,393 ) (507 ) Non-taxable gains on investments (5,880 ) — — Provision to return adjustment (6,705 ) (1,434 ) (533 ) Impact of changes in tax law (8,422 ) (4,746 ) (1,028 ) Italian allowance for corporate equity (9,243 ) (6,929 ) (5,355 ) Change in unrecognized tax benefits (10,914 ) (15,593 ) 427 Foreign tax differential (17,013 ) (48,407 ) 15,768 Other (5,069 ) 12,550 11,775 59,206 38,896 240,413 Effective tax rate 18.3 % (228.4 )% 70.7 % The Company’s effective income tax rate was 18.3% in 2016, as compared to (228.4)% in 2015 . The principal drivers of the change were one time non-deductible costs associated with the IGT acquisition in 2015, the non-recurring costs associated with the migration of the Parent company from Italy to the United Kingdom in 2015 and a reduction in operating losses in 2016 without tax benefits in certain foreign jurisdictions. The Company’s effective income tax rate was (228.4)% in 2015 as compared to 70.7% in 2014. The principal drivers of the change were costs associated with the IGT acquisition in 2015 that were either non-deductible for tax purposes or deductible at rates lower than the Company’s global blended statutory tax rate. The significant components reflected within the tax rate reconciliation labeled “Foreign tax differential” includes the effects of foreign subsidiaries’ earnings taxed at rates other than the U.K. statutory rate. On December 18, 2015, the Consolidated Appropriations Act 2016 was signed into law in the United States. Some of the provisions were retroactive to January 1, 2015, including the permanent extension of the U.S. research and development tax credit. The effective tax rate reflects the Company’s estimated 2016 and 2015 U.S. research and development tax credit. The U.K. 2015 Finance Bill received Royal Assent in the fourth quarter of 2015, which resulted in the enactment of the U.K. corporate tax rate change from 20% in 2015 to 19% in 2017, then 18% in 2020. As a result, the Company recorded $1.4 million of income taxes in the fourth quarter of 2015 to write down the U.K. net deferred tax asset. In December 2015, the Italian Government approved the reduction of the Italian federal tax rate from the current rate of 27.5% to 24% in 2017. As a result, the Company recorded an $11.8 million tax benefit in the fourth quarter of 2015 to write down Italy’s net deferred tax liability. The Company early adopted ASU 2016-09 in the fourth quarter of 2016. The primary impact of adoption required the Company to recognize all excess tax benefits and tax deficiencies in the income statement prospectively beginning in the first quarter of 2016. This could result in fluctuations in the effective tax rate period over period depending on how many awards vest during the year as well as the volatility of the stock price. At January 1, 2016, the Company had $3.3 million of excess tax deductions related to stock-based compensation that were tracked off balance sheet. The tax effect of these deductions was $1.2 million . The Company recorded a cumulative effect adjustment to retained earnings of $1.2 million to recognize these excess tax benefits on the balance sheet. The components of deferred tax assets and liabilities are as follows: December 31, ($ thousands) 2016 2015 Deferred tax assets: Net operating losses 266,547 292,439 Provisions not currently deductible for tax purposes 160,202 164,164 Depreciation and amortization 118,122 148,801 Jackpot timing differences 83,989 92,807 Credit carryforwards 38,618 40,578 Inventory reserves 15,974 6,820 Deferred revenue 9,129 10,184 Stock-based compensation 7,468 7,690 Other 15,897 15,062 Gross deferred tax assets 715,946 778,545 Valuation allowance (151,653 ) (139,663 ) Net deferred tax assets 564,293 638,882 Deferred tax liabilities: Acquired intangible assets 1,115,345 1,294,816 Depreciation and amortization 144,115 178,925 Foreign exchange on intra-group loan — 17,110 Other 35,381 41,375 Total deferred tax liabilities 1,294,841 1,532,226 Net deferred income tax liability (730,548 ) (893,344 ) The Company’s net deferred income taxes are recorded in the consolidated balance sheet as follows: December 31, ($ thousands) 2016 2015 Deferred income taxes - non-current asset 31,376 48,074 Deferred income taxes - non-current liability (761,924 ) (941,418 ) (730,548 ) (893,344 ) The Company has gross tax loss carryforwards in a number of tax jurisdictions of $1.214 billion that begin to expire in 2029, while others have an unlimited carryforward period. Portions of these tax loss carryforwards are subject to annual limitations, including Section 382 of the U.S. Internal Revenue Code of 1986, as amended, for U.S. tax purposes and similar provisions under other countries laws. The Company has tax credits carryforwards of $38.6 million , of which $25.8 million will expire in 2017 (the Company has a full valuation allowance on the $25.8 million tax credits) with the remaining tax credits expiring in various dates through 2036. A reconciliation of the beginning and ending amount of the valuation allowance is as follows: December 31, ($ thousands) 2016 2015 2014 Balance at beginning of year 139,663 77,631 86,742 Charges (credits) to expense 11,990 62,032 (9,111 ) Balance at end of year 151,653 139,663 77,631 The valuation allowance pertains to certain U.S. and foreign net operating loss and credit carryforwards that are not expected to be realized. In assessing the need for a valuation allowance, the Company considered both positive and negative evidence for each jurisdiction including past operating results, estimates of future taxable income and the feasibility of tax planning strategies. When the Company changes its determination as to the amount of deferred tax assets that can be realized, the valuation allowance is adjusted with a corresponding impact to the provision for income taxes in the period in which such determination is made. Deferred income taxes have not been recognized on the cumulative undistributed earnings of the Company’s non-UK subsidiaries as they have been either indefinitely reinvested or can be distributed tax free. Distribution of these earnings in the form of dividends or otherwise may result in a combination of income and withholding taxes payable in various countries. At December 31, 2016 , the positive undistributed earnings of the Company's non-UK subsidiaries amounts to approximately $2.017 billion . Due to complexities in tax laws and the various forms of repatriation that exist, it is not practicable to estimate the unrecognized amount of deferred income taxes and the related withholding taxes associated with the Company’s undistributed earnings. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows: For the year ended December 31, ($ thousands) 2016 2015 2014 Balance at beginning of year 37,370 6,296 7,536 Current year acquisition — 49,934 — Additions to tax positions - current year 423 9,462 98 Additions to tax positions - prior years 1,718 — — Reductions to tax positions - current year (652 ) — — Reductions to tax positions - prior years (12,755 ) (7,733 ) (1,338 ) Settlements (8,750 ) (5,313 ) — Lapses in statutes of limitations (3,014 ) (15,276 ) — Balance at end of year 14,340 37,370 6,296 At December 31, 2016 , 2015 and 2014 , $10.8 million , $30.1 million and $6.3 million , respectively, of the unrecognized tax benefits, if recognized, would affect the Company’s effective tax rates. The Company recognizes interest expense and penalties related to income tax matters in the provision for income taxes. For 2016 , 2015 and 2014 , the Company recognized $(0.1) million , $(10.0) million and $0.5 million , respectively, in interest expense and penalties. At December 31, 2016 , 2015 and 2014 , the gross balance of accrued interest was $3.6 million , $3.7 million and $3.0 million , respectively. Unrecognized tax benefits decreased during 2016 as a result of the settlement with the U.S. Internal Revenue Service ("IRS"). For 2016 , the additions to unrecognized tax benefits related to the current year are primarily attributable to U.S. tax issues. The Company files income tax returns in various jurisdictions of which the United Kingdom, United States and Italy represent the major tax jurisdictions. During the fourth quarter of 2016, the Internal Revenue Service (“IRS”) completed the examination for tax year 2011 for Legacy IGT. Also, during 2016, the Company was notified the IRS will audit the tax year 2015 and the tax year 2014 for Legacy GTECH. All tax years prior to 2012 are closed with the IRS. Both Legacy GTECH and Legacy IGT have income tax audits in various taxing jurisdictions. The years that may be examined vary, with the earliest year being 2010. In June 2015 a tax audit in Italy was initiated, which is also focused on the leveraged buyout transaction of GTECH Holdings Corporation in 2006 and subsequent acquisition debt refinancing. In July 2015, the Italian Tax Police issued a tax audit report (First Report) covering the years 2006-2010, alleging that GTECH did not recharge to GTECH Holdings Corporation all interest expense and other costs incurred in connection with the 2006 transaction and subsequent refinancing. Based on this tax report, in December 2015 the Italian Tax Agency issued a number of tax assessment notices to the Company covering the years 2006-2010 and alleging that additional taxes, penalties and interest for these years totaling €200.0 million are due. Under Italian Law, the Company had 60 days in which to appeal the tax assessment notice. On February 26, 2016, the Company submitted a Voluntary Settlement Request, which entitled the Company to an automatic 90 day extension. In the meantime, on April 12, 2016, the Parent received a Tax Audit report (Second Report) from the Italian Tax Police covering years 2011- 2014. Based upon this report, the additional taxes, penalties and interest associated with the transfer pricing challenge was estimated to be approximately €275 million for those years. During the mentioned extension period the Tax Agency re-examined the preliminary conclusions of the Tax Police in both First and Second Report and offered a tax settlement of an aggregate amount of €13.5 million ( $15.3 million ). The settlement procedure concluded on June 20, 2016 with the relevant tax payments made by the Parent. The above-mentioned settlement was booked as a reserve in the Company's 2016 Financial Statements. Finally, the two additional claims contained in the Second Report regarding (i) the alleged improper deduction of €140.0 million in Value Added Tax and (ii) under-reported taxable income pursuant to Italy’s controlled foreign corporation regime with specific reference to the Company’s fully controlled subsidiary incorporated in Cyprus, were abandoned by the Italian Tax Agency. Consequently, all of the tax assessments, penalty and interest claims emanating from the aforementioned tax audits have been resolved. Based upon the timing and outcome of examinations of the Parent, or the result of the expiration of statute of limitations for specific jurisdictions, it is reasonably possible that the related unrecognized tax benefits could change from those recorded in the consolidated balance sheets. The Company anticipates that several of these audits may be finalized within the next twelve months. While the Company expects the amount of the unrecognized tax benefits to change in the next twelve months, the Company does not expect the change to have a significant impact on the consolidated balance sheet or statement of operations.

The minimum amounts due for non-cancelable leases at December 31, 2016 are as follows ($ thousands): Year Operating Capital Total 2017 65,271 13,707 78,978 2018 55,454 7,187 62,641 2019 49,186 6,848 56,034 2020 34,093 6,014 40,107 2021 28,937 5,295 34,232 Thereafter 112,889 9,294 122,183 Total minimum payments 345,830 48,345 394,175 Less amount representing interest (13,127 ) Capitalized lease obligation 35,218 Facility capital lease The Company has a finance lease for a principal operating facility in Providence, Rhode Island. The Company has the right to cancel the lease after June 30, 2023 if its facilities management contract with the State of Rhode Island is not renewed, in exchange for a termination fee equal to six months of base rent plus operating expenses. The lease includes two 10 -year extension options. The Company has the unilateral right to extend the lease under the two extension options under the same terms as in the base term. The lease contains a restriction that does not allow the Company to assign the lease or sublease its portion of the building without the lessor’s approval, which is not to be unreasonably withheld. The lease has been accounted for under build-to-suit guidance, under which the Company carries the entire cost of the building on its books. The building will remain on the books for the lease term and is depreciated over its useful life of 40 years . At December 31, 2016 , the Company had no sublease arrangements at this facility. Communication equipment capital leases The Company has finance leases for certain communication equipment that expire between 2019 and 2022. The leases have terms of renewal, options to purchase the equipment and there are no escalation clauses. There are no restrictions placed upon the Company by entering into these leases. Point of sale capital leases The Company has finance leases for certain point of sale equipment that expire in 2017. There are no restrictions placed upon the Company by entering into these leases. Sale and Leaseback Transactions The Company sold its technology center facility in West Greenwich, Rhode Island in December 2006 and entered into a sale-leaseback agreement for a portion of the facility with the new owners that expires in November 2019, including renewal options. On December 30, 2015, the Company sold its Las Vegas, Nevada campus and entered into a sale-leaseback agreement with the new owners for a portion of the facility for a term of 15 years with optional renewals. Both the West Greenwich and Las Vegas facilities are accounted for as operating leases, and future minimum lease payments are included in the operating lease section in the table above. Jackpot Commitments Jackpot liabilities are recorded as current and non-current liabilities as follows: December 31, ($ thousands) 2016 Current liabilities 95,574 Non-current liabilities 203,468 299,042 Future jackpot payments are due as follows ($ thousands): Year Previous Winners Future Winners Total 2017 47,900 47,556 95,456 2018 34,901 9,023 43,924 2019 31,164 574 31,738 2020 27,591 574 28,165 2021 23,227 574 23,801 Thereafter 119,896 8,611 128,507 Future jackpot payments due 284,679 66,912 351,591 Unamortized discounts (52,549 ) Total jackpot liabilities 299,042 Contingencies Performance and other bonds In connection with certain contracts and procurements, the Company has been required to deliver performance bonds for the benefit of customers and bid and litigation bonds for the benefit of potential customers, respectively. These bonds, on which customers and potential customers have never made a claim, give the beneficiary the right to obtain payment and/or performance from the issuer of the bond if certain specified events occur. In the case of performance bonds, which generally have a term of one year , such events include the Company’s failure to perform its obligations under the applicable contract. In 2016, after selling the substantial majority of the Company's jackpot investments, the Company entered into Wide Area Progressive Bonds in order to secure those obligations. The following table provides information related to potential commitments for bonds outstanding at December 31, 2016 : ($ thousands) Total bonds Performance bonds 352,479 Wide Area Progressive bonds 285,986 Litigation bonds 31,013 All other bonds 6,950 676,428 Guarantees and indemnifications Incentive Payments and Penalties under Minimum Profit Contracts The Company has three contracts where it has provided customers with minimum profit level guarantees (the Illinois Contract, Indiana Contract and New Jersey Contract). Under these contracts the Company may earn incentive compensation if it exceeds minimum profit level guarantees and may be required to pay penalties should it fail to achieve them. In relation to the Illinois Contract, the Company guaranteed a minimum profit level to the State of Illinois for each fiscal year of the agreement, commencing with the State of Illinois’s fiscal year ended June 30, 2012. The amounts guaranteed and therefore amounts owed by the Company as shortfall payments under the Illinois Contract were under dispute. In December 2014, the Company and the State of Illinois entered into a termination agreement which settled the amount of shortfall payments for fiscal years 2012, 2013 and 2014, in the amounts of $21.8 million , $38.6 million and $37.1 million , respectively. In 2015, the Attorney General of the State of Illinois questioned the validity of the termination agreement between the Company and the State of Illinois which resulted in the Company and the State of Illinois entering into a new termination agreement and the Company paid the State of Illinois an additional $10 million representing the shortfall payment for the State of Illinois’s fiscal year ending June 30, 2015. The Company will neither be responsible for the payment of any other shortfall payment, nor will it be entitled to receive any incentive compensation, for all or any portion of fiscal year 2015, or any subsequent fiscal year. The Company recorded reductions of service revenue of $10.0 million and $55.5 million in 2015 and 2014 , respectively. In relation to the Indiana Contract, the Company guaranteed a minimum profit level to the State of Indiana commencing with the contract year starting July 1, 2013. The Company recorded reductions of service revenue of $8.0 million and $8.8 million in 2015 and 2014 , respectively related to this guarantee. In 2015, the Company and the State of Indiana renegotiated the Indiana Contract which resulted in revised guarantee levels and in consideration the Company paid the State of Indiana $18.3 million which the Company capitalized to Other Assets in its consolidated balance sheet and which the Company is amortizing to service revenue over the remaining contract term. In relation to the New Jersey Contract, the Company guaranteed a minimum profit level to the State of New Jersey commencing with the contract year starting July 1, 2014. In 2015, the Company and the State of New Jersey renegotiated the New Jersey Contract which resulted in revised guarantee levels and in consideration the Company paid the State of New Jersey $15.4 million which the Company capitalized to Other Assets in its consolidated balance sheet and which the Company is amortizing to service revenue over the remaining contract term. In 2016, the Company received a $30.6 million incentive payment based on its performance, which the Company recorded as service revenue in the consolidated statements of operations. Loxley GTECH Technology Co., LTD guarantee The Company has a 49% interest in Loxley GTECH Technology Co., LTD (“LGT”), which is accounted for as an asset held for sale with a minimal value. LGT is a joint venture that was formed to provide an online lottery system in Thailand. The Company has guaranteed, along with the 51% shareholder in LGT, performance bonds provided to LGT by an unrelated commercial lender. The performance bonds relate to LGT’s performance under the July 2005 contract between the Government Lottery Office of Thailand and LGT should such contract become operational. The Company is jointly and severally liable with the other shareholder in LGT for this guarantee. There is no scheduled termination date for the Company’s guarantee obligation. At December 31, 2016, the maximum liability under the guarantee was Baht 375 million ( $10.5 million ), and the Company does not have any obligation related to this guarantee because the July 2005 contract to provide the online lottery system is not in operation due to continuing political instability in Thailand. Commonwealth of Pennsylvania indemnification The Company will indemnify the Commonwealth of Pennsylvania and any related state agencies for claims made relating to the state’s approval of IGT Global Solutions Corporation’s manufacturer’s license in the Commonwealth of Pennsylvania. Legal Proceedings From time to time, the Parent and/or one or more of its subsidiaries are party to legal, regulatory, or administrative proceedings regarding, among other matters, claims by and against the Company, injunctions by third parties arising out of the ordinary course of business, and investigations and compliance inquiries related to the Company’s ongoing operations. Legal proceedings can be expensive and disruptive to normal business operations. Moreover, the results of legal proceedings are often difficult to predict and the Company’s view of these matters may change as the related proceedings and events unfold. The Company expenses legal fees as incurred and records a provision for contingent losses when it is both probable that a liability will be incurred and the amount or range of the loss can be reasonably estimated. At December 31, 2016 , provisions for litigation matters amounted to $4.0 million . With respect to litigation and other legal proceedings where the Company has determined that a loss is reasonably possible but the Company is unable to estimate the amount or range of reasonably possible loss, in excess of amounts already accrued, no additional amounts have been accrued (given the uncertainties of litigation and the inherent difficulty of predicting the outcome of legal proceedings). If material, an unfavorable outcome to any legal matter could have an adverse effect on the Company’s operations or the Parent's financial position, liquidity, or results of operations. Brazil ICMS Tax Since 1997, GTECH Brazil paid ISS service taxes on printing ribbons, rolls of paper and wagering slips (“Consumables”) distributed to lottery outlets. On July 26, 2005 the State of São Paulo challenged this tax classification, claiming the higher ICMS tax (Brazilian VAT) should apply instead. On February 27, 2017, the Brazilian court ruled that rolls of paper and wagering slips were not subject to ICMS, but printing ribbons were, although at a lower tax rate than the São Paulo tax authorities had applied. Both parties will likely appeal. The net claim after the current ruling, plus statutory interest and fees is approximately 18.5 million Brazilian Reals (approximately $5.7 million at exchange rates in effect at December 31, 2016). GTECH Brazil will continue to defend against the tax authorities’ assessment; Brazilian counsel advises the appellate proceedings are likely to take several years. Texas Fun 5’s Instant Ticket Game Five lawsuits have been filed against IGT Global Solutions Corporation (f/k/a GTECH Corporation) in Texas state court arising out of the Fun 5’s instant ticket game sold by the Texas Lottery Commission (“TLC”) from September 14, 2014 to October 21, 2014. Plaintiffs allege each ticket’s instruction for Game 5 provided a 5x win (five times the prize box amount) any time the “Money Bag” symbol was revealed in the “5X BOX”. However, TLC awarded a 5x win only when (1) the “Money Bag” symbol was revealed and (2) three symbols in a pattern were revealed. (a) Steele, James et al. v. GTECH Corp. , filed on December 9, 2014 in Travis County (No. D1GN145114). Through intervenor actions, over 1,200 plaintiffs claim damages in excess of $500 million . GTECH Corporation’s motion to dismiss based on Derivative Governmental Immunity was denied. GTECH Corporation has appealed; the ruling on the appeal is pending. (b) Nettles, Dawn v. GTECH Corp. et al. , filed on January 7, 2015 in Dallas County (No. 051501559CV). Plaintiff claims damages in excess of $4 million . GTECH Corporation and the Texas Lottery Commission won motions to dismiss based on Derivative Governmental Immunity. Plaintiff has appealed; the ruling on plaintiff’s appeal is pending. (c) Guerra, Esmeralda v. GTECH Corp. et al. , filed on June 10, 2016 in Hidalgo County (No. C277716B). Plaintiff claims damages in excess of $500,000 . (d) Wiggins, Mario & Kimberly v. IGT Global Solutions Corp. , filed on September 15, 2016 in Travis County (No. D1GN16004344). Plaintiff claims damages in excess of $1 million . (e) Campos, Osvaldo Guadalupe et al. v. GTECH Corp. , filed on October 20, 2016 in Travis County (No. D1GN16005300). Plaintiff claims damages in excess of $1 million . The Company disputes the claims made in each of these cases and continues to defend against these lawsuits. Illinois State Lottery On February 2, 2017, putative class representatives of retailers and lottery ticket purchasers alleged the Illinois Lottery collected millions of dollars from sales of instant ticket games and wrongfully ended certain games before all top prizes had been sold. Raqqa, Inc. et al. v. Northstar Lottery Group, LLC. , was filed in Illinois state court, St. Clair County (No. 17L51) against Northstar Lottery Group LLC, a consortium in which the Parent indirectly holds an 80% controlling interest. The claims include tortious interference with contract, violations of Illinois Consumer Fraud and Deceptive Practices Act, and unjust enrichment. The lawsuit was removed to Illinois U.S. District Court. On March 15, 2017, a second lawsuit, Atteberry, Dennis et al. v. Northstar Lottery Group, LLC , was filed in Illinois state court, Cook County (No. 2017CHO3755) seeking damages on the same matter. The Company disputes the claims made in both cases and continues to defend against these lawsuits. Mexican Inventory Tax The Mexican Tax Administration Service levied an assessment of income tax, VAT, interest and penalties on GTECH Mexico, S.A. de C.V. (“GTECH Mexico”), for the 2006 fiscal year in the amount of 424,486,923 Mexican Pesos (approximately U.S. $20.5 million at the exchange rate in effect on December 31, 2016). Approximately U.S. $15 million of the assessment relates to denial of a deduction for inventory sold by GTECH Mexico to its parent; the remaining assessment relates to intercompany loan proceeds received from GTECH Mexico’s parent. Although lower courts upheld the assessment, on October 28, 2016, the Mexican Appellate Court ruled that the loan proceeds are non-taxable, but denied the Company’s inventory tax deduction. On December 2, 2016, the Company filed an appeal to the Mexican Supreme Court of Justice with respect to the inventory tax issue. The Company maintains that the assessment is without merit. Disposition of Previously Disclosed Matters Set forth below are legal proceedings that were previously disclosed and for which a disposition occurred during 2016 or in 2017 through April 19, 2017. Italian Tax Matters In December 2013, further to a tax audit received in 2012, settled by the Parent’s predecessor entity GTECH S.p.A (“GTECH”), the Italian Tax Agency, as required by Italian law, referred the matter to the Rome Public Prosecutor’s office, which had the obligation to start an investigation. Within the context of this investigation, on April 28, 2015, representatives of the Rome Public Prosecutor came to the Company's offices in Rome to collect documents and files. The CEO, a board member and a senior executive of the Parent were served with a notice that each is subject to a criminal investigation in Italy relating to the Italian tax returns filed by GTECH for the tax years 2006-2013. Under the relevant Italian statutes, the legal representative and the signatories of the corporate tax returns, and not the corporation itself, are subject to investigation. The individuals are Lorenzo Pellicioli, then Chairman of GTECH’s Board of Directors and currently Vice-Chairman of the Parent’s Board of Directors, who was GTECH’s legal representative who signed the Italian corporate tax return for the 2013 tax year; Marco Sala, then GTECH’s CEO and the current CEO, director and the legal representative of the Parent, who signed the Italian corporate tax returns for the 2006, 2007 and 2008 tax years, and Renato Ascoli, then the general manager of GTECH’s Italian operations, who signed the Italian corporate tax returns for the 2009, 2010, 2011, and 2012 tax years. The investigation involves the structuring of the original leveraged buyout of GTECH Holdings Corporation by Lottomatica S.p.A. and the subsequent conversion of a portion of the original debt incurred by GTECH Holdings Corporation into an equity increase from the parent company, Lottomatica S.p.A. The Public Prosecutor is focused on determining whether GTECH’s income was under-reported in Italy for any of the tax years 2006-2013. Under Italian law, the Public Prosecutor may choose to bring criminal charges against any or all of the above-referenced individuals in the event that income was under-reported in one or more tax years. As a consequence of the investigation, a further Tax Audit started on June 22, 2015, focusing on the 2006 merger leveraged buyout acquisition of GTECH Holdings Corporation and the subsequent acquisition debt re-financing. On July 7, 2015, the Tax Police notified a Tax Audit Report (the "First Report") to the Parent, alleging that GTECH breached the Italian transfer pricing rule (article 110, par. 7, of the Income Tax Act) because it did not recharge to its U.S. wholly-owned subsidiary GTECH Holdings Corporation all the interest expense and other costs incurred in connection with the 2006 acquisition and its subsequent re-financing. The First Report covered the tax years 2006 to 2010. As provided by Italian law, the Tax Police Audit Report was delivered to the Public Prosecutor and the Italian Tax Agency for their independent evaluation. Under Italian law, the Italian Tax Agency is the only authority empowered to issue a tax assessment, based on the Tax Police Audit Report’s allegations. On December 30, 2015, the Company received a number of tax assessment notices (so-called Avvisi di Accertamento) covering the years 2006-2010 and alleging that additional taxes, penalties and interest totaling €200 million were due. Under Italian law, the Company had 60 days to appeal the tax assessment notice. On February 26, 2016 the Company submitted a Voluntary Settlement Request, which entitled the Company to an automatic 90 day extension. In the meantime, on April 12, 2016, the Company received a Tax Audit Report (the "Second Report") from the Tax Police, covering years 2011 to 2014. Based on this report, the additional taxes, penalties and interest associated with the transfer price challenge was estimated to be approximately €275.0 million for those years. During the aforementioned 90-day extension period, the Italian Tax Agency re-examined the preliminary conclusions of the Tax Police in the First Report and the Second Report and offered a tax settlement of an aggregate amount of €13.5 million . The settlement procedure concluded on June 20, 2016, with the relevant tax payments made by the Parent. Finally, the two additional claims contained in the Second Report regarding (i) the alleged improper deduction of €140.0 million in Value Added Tax and (ii) under-reported taxable income pursuant to Italy’s controlled foreign corporation regime with specific reference to the Company’s fully controlled subsidiary incorporated in Cyprus, were definitively abandoned by the Italian Tax Agency. Consequently, all of the tax assessments, penalty and interest claims emanating from the aforementioned tax audits have been resolved. In the Matter of International Game Technology On February 3, 2016, International Game Technology received a "Wells Notice" from the staff of the SEC solely relating to its investigation of an alleged retaliation claim under the Securities Exchange Act of 1934, as amended. The Parent announced a settlement with the SEC on September 30, 2016. In agreeing to a settlement payment of $500,000 to the SEC, the Parent neither admitted nor denied that pre-Merger International Game Technology improperly retaliated against a whistleblower.

Redeemable Non-Controlling Interests	Redeemable Non-Controlling Interests In March 2016, the Company, through its subsidiary Lottomatica S.p.A. (“Lottomatica”), Italian Gaming Holding a.s., Arianna 2001 and Novomatic Italia (collectively the "Members") entered into a consortium (Lottoitalia S.r.l. or "Lottoitalia") to bid on the Italian Gioco del Lotto service concession (the “Lotto Concession”). On May 16, 2016, Lottoitalia was awarded management of the Lotto Concession for a nine -year term. Under the terms of the consortium agreement, Lottomatica is the principal operating partner to fulfill the requirements of the Lotto Concession. The Members will make capital contributions to Lottoitalia of €908.2 million (of which €600 million ( $665.3 million ) was made in 2016), on a pro rata basis based on each party’s equity ownership interest, with Lottomatica having a 61.5% equity ownership interest. These contributions finance €770 million in upfront concession payments and an estimated €138.2 million to upgrade the technological infrastructure supporting the Lotto Concession. The remaining capital contributions will be completed by April 2017. Ownership in Lottoitalia, which the Company fully consolidates as a variable interest entity, is as follows at December 31, 2016: Name of entity % Ownership Lottomatica, S.p.A. 61.50 % Italian Gaming Holding a.s. 32.50 % Arianna 2001 4.00 % Novomatic Italia 2.00 % The Company determined Lottoitalia to be a variable interest entity relative to the Company's risks and rewards of the investment and Lottoitalia's current need for funding to finance planned operations. All annual profits of Lottoitalia will be distributed to the Members within five business days of the approval of its annual financial statements. In addition, Lottoitalia will make in every year, for a period of nine years, quarterly (beginning with the second quarter of 2017), equal distributions of cash to the Members in an aggregate amount equal to that additional paid in surplus but excluding any reserves deriving from profits or retained earnings generated in previous quarters. Each distribution will be made pro rata to the Members ownership interest in Lottoitalia. In connection with the formation of Lottoitalia, Lottomatica S.p.A. entered into an agreement with IGH in May 2016, which contains the following put/call options: • Underperformance put option - IGH has the right, at its discretion, to sell its interest in Lottoitalia to Lottomatica S.p.A. in the event that Lottoitalia underperforms relative to its approved financial projections in 2017. The put option is exercisable by IGH beginning on the date of approval of Lottoitalia's financial statements for the year ending December 31, 2017 and ending 60 days thereafter. • Deadlock put/call option - IGH has the right, at its discretion, to sell its interest in Lottoitalia to Lottomatica S.p.A. and Lottomatica S.p.A. has a reciprocal call right, in the event of certain specified events as defined in the agreement. The put/call options expire 60 days following written notice by either party following the applicable event. The strike price of the options is determined based on a specified formula as defined in the agreement. The Company determined that it is not currently probable that IGH's non-controlling interest will be redeemed as the underperformance put option contains discounts that would be applied to the fair value of Lottoitalia and the Deadlock put/call options can not be exercised unilaterally. The Company has recorded the non-controlling interest initially at fair value and no fair value adjustments will be recorded unless it becomes probable that IGH will redeem its non-controlling interest. The following table reconciles the activity in IGH's redeemable non-controlling interest in 2016: December 31, ($ thousands) 2016 Balance at beginning of year — IGH capital contribution 215,684 Income allocated to IGH 7,457 Balance at end of year 223,141

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation Incentive Awards Stock-based incentive awards are provided to directors and employees under the terms of the Company’s 2015 Equity Incentive Plan (the “Plan”) as administered by the Board. Awards available under the Plan principally include stock options, performance share units, restricted share units or any combination thereof. The maximum number of shares that may be granted under the Plan is 11.5 million shares. To the extent any award is forfeited, expires, lapses, or is settled for cash, the award is available for reissue under the Plan. The Company utilizes authorized and unissued shares to satisfy all shares issued under the Plan. Prior to 2015, stock options and performance share units were provided to employees under the terms of annual performance based plans (the “Old Plans”) as approved by the Board. There are 0.2 million shares available for issuance under the Old Plans. No shares were issued under the Old Plans in 2016 or 2015 and shares are not expected to be issued under the Old Plans in the future. Stock Options Stock options are awards that allow the employee to purchase shares of the Company’s stock at a fixed price. Stock options are granted under the Plan at an exercise price not less than the fair market value of a share on the date of grant. No stock options were granted in 2016. In 2015, stock options were granted solely to the Company’s Chief Executive Officer, vest in approximately two years from the date of grant subject to certain performance and other criteria, and have a contractual term of approximately seven years. Stock Awards Stock awards are principally made in the form of performance share units (PSUs) and restricted share units (RSUs). PSUs are stock awards where the number of shares ultimately received by the employee depends on the Company’s performance against specified targets. PSUs have a contractual term of 10 years and typically vest 50% over an approximate three -year period and 50% over an approximate four -year period. PSUs awarded in 2015 vest 50% over an approximate one -year period and 50% over an approximate two -year period. Dividend equivalents are not paid under the Plan. The fair value of each PSU is determined on the grant date, based on the Company’s stock price, adjusted for the exclusion of dividend equivalents, and assumes that performance targets will be achieved. Over the performance period, the number of shares of stock that will be issued is adjusted based upon the probability of achievement of performance targets. The ultimate number of shares issued and the related compensation cost recognized as expense is based on a comparison of the final performance metrics to the specified targets. RSUs are stock awards granted to directors and employees that entitle the holder to shares of common stock as the award vests, typically over a one -year period, and have a contractual term of 10 years . Dividend equivalents are not paid under the Plan. Stock Option Activity A summary of the Company’s stock option activity and related information is as follows: Weighted Average Stock Options Exercise Price Per Share ($) Remaining Contractual Term (in years) Aggregate Intrinsic Value ($ thousands) Outstanding at January 1, 2016 5,593,103 18.31 Forfeited (551,543 ) 20.54 Exercised (1,293,566 ) 15.17 Expired (726 ) 11.81 Outstanding at December 31, 2016 3,747,268 19.06 2.59 At December 31, 2016: Vested and expected to vest 3,372,776 18.93 2.87 22,231 Exercisable 1,795,032 18.40 1.54 12,789 The total intrinsic value of stock options exercised was $7.8 million , $3.3 million and $2.8 million in 2016 , 2015 and 2014 , respectively. Fair Value of Stock Options Granted The Company estimates the fair value of stock options at the date of grant using a valuation model that incorporates key inputs and assumptions as detailed in the table below. The weighted average grant date fair value of stock options granted during 2015 and 2014 was $2.31 and $3.08 per share, respectively. 2015 2014 Valuation model Monte Carlo Binomial Exercise price ($) 15.53 25.03 Expected option term (in years) 2.38 4.49 Expected volatility of the Company’s stock (%) 35.00 27.72 Risk-free interest rate (%) 1.06 0.25 Dividend yield (%) 5.15 3.63 The expected volatility assumes the historical volatility is indicative of future trends, which may not be the actual outcome. The expected option term is based on historical data and is not necessarily indicative of exercise patterns that may occur. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by employees who receive equity awards, and subsequent events are not indicative of the reasonableness of the original estimates of fair value made by the Company.

The total vest-date fair value of RSUs vested was $15.9 million and $8.4 million for 2016 and 2015 , respectively. No RSUs vested in 2014 . Fair Value of Stock Awards Granted During 2016 and 2015 , the Company estimated the fair value of PSUs at the date of grant using a Monte Carlo simulation valuation model, as the award includes a market condition. During 2014 , the Company estimated the fair value of PSUs at the date of grant using the average share price during the employee grant acceptance period. During 2016 and 2015 , the Company estimated the fair value of RSUs at the date of grant based on the Company’s stock price adjusted for the exclusion of dividend equivalents.

The modification affected 58 employees but did not result in any incremental compensation cost. During the fourth quarter of 2015, the Company modified the performance conditions of outstanding stock options and PSUs granted in July 2013 and 2014, as the original vesting conditions were not expected to be satisfied. The modification affected 223 employees and resulted in $14.6 million of incremental compensation cost. 2014 During the second quarter of 2014, the Company modified the performance conditions of outstanding stock options and PSUs granted in July 2012 and 2013, as the original vesting conditions were not expected to be satisfied.

In addition, 1.5 million outstanding stock options and unvested restricted stock awards were excluded from the computation of diluted earnings per share in 2015 because including them would have had an antidilutive effect due to the net loss position of the Company. There were no stock options or unvested restricted stock awards outstanding in 2016 or 2014 that were considered antidilutive and excluded from the diluted earnings per share calculation.

Principles of Consolidation	Principles of Consolidation The accompanying consolidated financial statements include the accounts of International Game Technology PLC and its consolidated subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The consolidated financial statements are presented in U.S. dollars and all amounts are rounded to the nearest thousand (except share and per share data) unless otherwise indicated. Investments in other entities that the Company has the ability to control, through a majority voting interest or otherwise, or with respect to which the Company is the primary beneficiary, are consolidated. Earnings or losses attributable to any non-controlling interests or redeemable non-controlling interests in a subsidiary are included in net income (loss) in the consolidated statements of operations. Any investments in affiliates over which the Company has the ability to exert significant influence, but do not control and with respect to which the Company is not the primary beneficiary, are accounted for using the equity method of accounting. Investments in affiliates for which the Company has no ability to exert significant influence are accounted for using the cost method of accounting. A Variable Interest Entity ("VIE") is an entity that by design possesses the following characteristics: • The equity investment at risk is not sufficient for the entity to finance its activities without additional subordinated financial support; or • As a group, the holders of equity investment at risk do not possess: 1. The power, through voting rights or similar rights, to direct the activities that most significantly impact the entity's economic performance; or 2. The obligation to absorb expected losses or the right to receive the expected residual returns of the entity; or 3. Symmetry between voting rights and economic interests and where substantially all of the entity's activities either involve or are conducted on behalf of an investor with disproportionately fewer voting rights (i.e., structures with non-substantive voting rights). In determining whether the Company is the primary beneficiary of a VIE for financial reporting purposes, the Company considers whether it has the power to direct the activities of the VIE that most significantly impact the economic performance of the VIE and whether it has the obligation to absorb losses or the right to receive returns that would be significant to the VIE. The Company consolidates VIEs when it is the primary beneficiary.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, the reported amounts of revenues, costs and expenses during the reporting period and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. Significant estimates and judgments relied upon by the Company in preparing these financial statements include the timing of revenue recognition; the fair value assigned to acquired assets and assumed and contingent liabilities, associated with business combinations; expensing or capitalizing research and development costs for software development; the funding amount for Wide Area Progressive jackpot payments; minimum profit level guarantees; the assessment of legal and other contingencies; the determination of whether the Company is the primary beneficiary of a VIE, the determination of the probability of redemption of redeemable non-controlling interests, and the amount of the provision for income taxes and the valuation of deferred taxes and intangible assets, including goodwill.
Foreign Currency Translation	Foreign Currency Translation The functional currency of the Company's subsidiaries located outside of the United States are determined in accordance with authoritative guidance issued by the Financial Accounting Standards Board, or FASB. Assets and liabilities for these subsidiaries are translated at exchange rates in effect at the balance sheet date. Income and expense accounts for these subsidiaries are translated at the average exchange rates for the periods. Resulting translation adjustments are recorded as a component of accumulated other comprehensive income (loss) within shareholders’ equity. The Company records gains and losses from currency transactions denominated in currencies other than the functional currency in its consolidated statement of operations. Local currency transactions of subsidiaries located outside of the United States where the U.S. dollar is the functional currency are remeasured into U.S. dollars using current rates of exchange for monetary assets and liabilities and historical rates of exchange for non-monetary assets and liabilities. Gains and losses from remeasurement of monetary assets and liabilities are recorded in the consolidated statement of operations.
Acquisitions	Acquisitions The Company accounts for acquired businesses using the acquisition method of accounting, which requires that the assets acquired, liabilities assumed, contractual contingencies and contingent consideration be recorded at the date of acquisition at their respective fair values. Goodwill represents the excess of the purchase price, including the fair value of any contingent consideration, over the fair value of the net assets acquired. It further requires (1) acquisition related costs to be recognized separately from the acquisition and expensed as incurred, (2) most restructuring costs to be expensed in periods subsequent to the acquisition date and (3) changes in accounting for deferred tax asset valuation allowances and acquired income tax uncertainties after the measurement period to be reflected in the provision for income taxes. The operating results of acquisitions are included in the consolidated financial statements from the date control is obtained. Acquisition and disposition related costs are included in the consolidated statement of operations within “Transaction expense, net”. Transaction expense, net is composed of transaction costs on significant business combinations and significant gains and losses incurred on disposals of group entities or businesses. The fair value of identifiable intangible assets is based on significant judgments made by the Company, including the selection of the appropriate valuation methodologies and the determination of the economic lives of the assets acquired. These estimates and assumptions are based on historical and industry experience, information obtained from management of the acquired business, and also include, but are not limited to, future expected cash flows earned from the identified intangible assets and discount rates applied in determining the present value of those cash flows. Unanticipated events and circumstances may occur that could affect the accuracy or validity of such assumptions, estimates or actual results. Acquired identifiable intangible assets are amortized using the straight-line method over their estimated economic lives. Amortization of acquired software-related intangibles is included in cost of services and cost of product sales and amortization of other acquired intangible assets is included in selling, general and administrative expenses in the consolidated statement of operations.
Goodwill, Intangible Assets and Long-Lived Assets	Goodwill, Intangible Assets and Long-Lived Assets Goodwill is tested for impairment annually at the reporting unit level, which is one level below or the same level as an operating segment. The Company has five reporting units as follows: • North America Gaming and Interactive; • DoubleDown; • North America Lottery; • International; and • Italy. When testing goodwill for impairment, the Company first performs a qualitative assessment to determine whether it is necessary to perform step one of a two-step annual goodwill impairment test for each reporting unit. The first step of the two-step process is to identify whether a potential impairment exists by comparing the estimated fair values of the reporting units with their respective book values, including goodwill. If the estimated fair value of the reporting unit exceeds book value, goodwill is not considered impaired, and no additional steps are necessary. If the fair value of the reporting unit is less than book value, then the second step is performed to determine if goodwill is impaired and to measure the amount of impairment loss, if any. The amount of the impairment loss is the excess of the carrying amount of the goodwill over its estimated fair value. The estimate of fair value of goodwill is primarily based on an estimate of the discounted cash flows expected to result from that reporting unit, but may require valuations of certain internally generated and unrecognized intangible assets such as software, technology, patents and trademarks. If the carrying amount of goodwill exceeds the estimated fair value of that goodwill, an impairment loss is recognized in an amount equal to the excess. The Company also evaluates indefinite-lived intangible assets for impairment annually and whenever events or changes in circumstances indicate impairment may exist. The Company first performs a qualitative assessment to determine whether it is more likely than not that the fair value of indefinite-lived intangible assets are less than their carrying amount and whether the quantitative analysis is necessary. The quantitative analysis compares the fair value of indefinite-lived intangible assets to their carrying amount and an impairment loss is recognized when the carrying amount exceeds the fair value. The process of evaluating the potential impairment related to goodwill and indefinite-lived intangible assets is highly subjective and requires the application of significant judgment. If an event occurs that would cause revisions to the estimates and assumptions used in analyzing the value of goodwill and other intangible assets with indefinite lives, the revision could result in a non-cash impairment loss that could have a material impact on the Company’s financial results. The Company’s annual review of goodwill and indefinite-lived intangible assets for impairment is performed as of November 1 each year. The 2016 review resulted in impairment losses of $30.0 million in the DoubleDown reporting unit for certain indefinite lived trademarks relating to the forecasted slowing of growth in the social gaming market. The 2015 review resulted in impairment losses of $9.7 million in the International segment for certain indefinite lived trademarks. The Company evaluates long-lived assets, including identifiable intangible assets and other assets, for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. Events or changes in circumstances that could result in an impairment review include, but are not limited to, significant underperformance relative to historical or projected future operating results, significant changes in the manner of use of the acquired assets or the overall business strategy and significant negative industry or economic trends. Impairment is recognized when the asset is not recoverable and the carrying amount of an asset exceeds its fair value as calculated on a discounted cash flow basis. If an event occurs necessitating revised estimates and assumptions previously used in analyzing the value of property and equipment or finite-lived intangibles and other assets, that revision could result in a non-cash impairment loss that could have a material impact on the Company’s financial results. The Company recorded impairment losses related to long-lived assets of $7.7 million , $2.8 million and $2.6 million in 2016 , 2015 and 2014 , respectively.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company applies the authoritative guidance on fair value measurements for financial assets and liabilities that are measured at fair value on a recurring basis, as well as those financial assets and liabilities that are not measured at fair value but for which fair value is disclosed. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (exit price), in the principal or most advantageous market, in an orderly transaction between market participants, on the measurement date. The guidance establishes a three-tiered fair value hierarchy that prioritizes inputs to valuation techniques used in fair value calculations. The three levels of inputs are defined as follows: Level 1: Unadjusted quoted prices for identical assets or liabilities in active markets accessible by the Company at the measurement date. Level 2: Inputs that are observable in the marketplace other than those inputs classified as Level 1, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3: Inputs that are unobservable in the marketplace and significant to the valuation. Valuation methods and assumptions used to estimate fair value, when quoted market prices are not available, are subject to judgments and changes in these factors can materially affect fair value estimates. For financial assets and financial liabilities that are recognized at fair value on a recurring basis, the Company determines whether transfers have occurred between levels in the hierarchy by re-assessing categorization (based on the lowest level input that is significant to the fair value measurement as a whole) at the end of each reporting period. The carrying amounts reported in the consolidated balance sheets for cash and cash equivalents, restricted cash and investments, accounts receivable, other current assets, accounts payable, and other current liabilities approximate fair value due to relatively short periods to maturity.
Derivative Instruments	Derivative Instruments The Company uses derivative instruments to manage the impact of foreign currency exchange and interest rate changes on earnings and cash flows. The Company does not enter into derivative instruments for speculative purposes. It is the Company’s policy to negotiate the terms of the derivative to match the terms of the hedged item to maximize hedge effectiveness. Derivative instruments are recognized as either assets or liabilities on the balance sheet at fair value. Accounting for changes in the fair value of the derivative depends on the nature of the hedge and the hedge effectiveness as described further below. Derivative gains and losses are reported as operating activities within the consolidated statement of cash flows. The Company uses foreign currency forward and option contracts to offset its exposure to the change in value of certain foreign currency denominated monetary assets and liabilities. Since these derivatives hedge existing exposures that are denominated in foreign currencies, the contracts do not qualify for hedge accounting. Accordingly, these outstanding non-designated derivatives are recognized on the consolidated balance sheet at fair value with the changes in fair value recorded in foreign exchange gain (loss), net, in the consolidated statement of operations. These derivative contracts mature in less than 1 year . The Company also uses foreign currency forward and option contracts to hedge its exposure on certain forecasted foreign currency revenue and expense transactions. The terms of the contracts are typically matched with the forecasted foreign currency transactions to be derived from operations up to a period of 12 months. These derivatives are designated as cash flow hedges. All outstanding cash flow hedges are recognized on the consolidated balance sheets at fair value with the effective portion of the gain or loss recorded in accumulated other comprehensive income (loss). When the underlying hedged transaction is recognized, the effective portion of the gain or loss on the derivative instrument is reclassified from accumulated other comprehensive income (loss) to the consolidated statement of operations, in the related revenue or expense caption, as appropriate. Any ineffectiveness is recognized immediately into earnings. There was no ineffectiveness for any period presented. The Company uses interest rate derivative instruments designated as fair value hedges to manage the exposure to interest rate movements and to reduce borrowing costs by converting fixed-rate debt into floating-rate debt. Under these agreements, the Company agrees to exchange, at specified intervals, the difference between fixed and floating interest amounts calculated by reference to agreed-upon notional principal amounts. Changes in the fair value of the derivative instrument are recorded in other income or expense and are offset by changes in the fair value of the underlying debt instrument due to changes in the benchmark interest rate. The cash flows from these contracts are reported as operating activities in the consolidated statement of cash flows. The gains (losses) from terminated interest rate swap agreements are recorded in long-term debt, increasing (decreasing) the outstanding balances of the debt, and amortized as a reduction (addition) of interest expense over the remaining life of the related debt. The cash flows from the termination of the interest rate swap agreements are reported as financing activities in the consolidated statement of cash flows.
Debt Issuance Costs and Premiums/Discounts	Debt Issuance Costs and Premiums/Discounts The Company accounts for incremental costs directly attributable to realizing the proceeds of a debt issuance and the difference between the net proceeds received upon debt issuance and the amount payable at maturity as adjustments to the carrying amount of the debt on its consolidated balance sheets. These adjustments are amortized to interest expense using the effective interest method over the estimated term of the debt, typically the contractual term.
Revenue Recognition	Revenue Recognition The Company has two categories of revenue: Service revenue and Product sales. Service revenue is derived from the following sources: • Operating contracts predominantly related to Italian contracts and certain U.S. contracts; • Gaming operations arrangements where the Company provides customers with proprietary gaming equipment, systems, content licensing, and services; • Facilities Management Contracts (Hosting arrangements); • Interactive contracts; and • Post-contract customer support (“PCS”). Product sales are derived from the following sources: • Sale of lottery terminals and gaming machines, including game content; and • Sale of lottery and gaming systems, including the licensing of proprietary software, and including implementation services. Revenue is recognized when all of the following conditions are met: (i) Persuasive evidence of an arrangement exists; (ii) Delivery has occurred; (iii) The fee is fixed or determinable; and (iv) Collectability is probable. Revenues are reported net of amortization of upfront payments to customers, incentives, rebates, and discounts. Sales taxes, gaming taxes and other taxes of a similar nature are presented on a net basis (excluded from revenue). Amounts billed prior to completing the earnings process are deferred until revenue recognition criteria is met. Service revenue Service revenue is derived from the following types of arrangements: Operating contracts Certain of the Company’s revenue, primarily revenue from the Italy segment and to a lesser extent the North America Lottery segment, is derived from operating contracts. Under operating contracts, the Company manages all the activities along the lottery value chain including collecting wagers, paying out prizes, managing all accounting and other back-office functions, running advertising and promotions, operating data transmission networks and processing centers, training staff, providing retailers with assistance and supplying materials for the game. In Italian arrangements where the Company is performing services on behalf of the government and the government is considered the Company’s customer, revenue is recognized net of prize payments, taxes, retailer commissions and remittances to state authorities, because the Company is acting as an agent to the authorities. In arrangements where the Company’s customers are the end players and/or retailers, the Company records revenue net of prizes and taxes only, and records the retailer commissions as a cost of service, because the Company is acting as the principal. The Company also provides sports pools and sports betting services. Under sports pools arrangements, the Company manages the sports pool where the sports pool prizes are divided among those players who select the correct outcome. There are no odds involved in sports pools and each winner’s payoff depends on the number of players and the size of the pool. Under sports pools arrangements, the Company collects the wagers, pays prizes, pays a percentage fee to retailers, withholds its fee, and remits the balance to the respective regulatory agency. The Company assumes no risk associated with sports pool wagering. The Company records revenue net of prize payouts, gaming taxes, retailer commissions and remittances to state authorities, because the Company is acting as an agent to the authorities. In sports betting contracts, the Company establishes and assumes the risks related to the odds. Under fixed odds betting, the potential payout is fixed at the time bets are placed and the Company bears the risk of odds setting. The Company is responsible for collecting the wagers, paying prizes, and paying fees to retailers. The Company retains the remaining cash as profits. Under these arrangements, the Company records revenue net, calculated as total wagers less the estimated payout for prizes, because the betting contract is considered a derivative and is required to be recorded at fair value. Taxes are recorded as contra revenue and retailer commissions are shown as expenses. Fees earned under operating contracts are recognized as revenue in the period earned and are classified as service revenue in the consolidated statement of operations when all of the criteria outlined above are met. Under operating contracts, the Company is generally required to pay upfront license fees. When such upfront payments are made to the Company’s customers, the payment is recorded as a non-current asset and amortized as a reduction of service revenue over the license term. Gaming Operations Gaming operations revenues are generated by providing customers with proprietary land-based gaming equipment, systems, content licensing, and services under a variety of recurring revenue arrangements, including a percentage of coin-in (amounts wagered), a percentage of net win, or a fixed daily/monthly fee. Included in gaming operations are Wide Area Progressive (“WAP”) systems. WAP systems consist of linked slot machines located in multiple casino properties, connected to a central computer system. WAP games differ from all other games in that a Company-sponsored progressive jackpot increases with every wager until a player wins the top award combination. Casinos with WAP machines pay a percentage of the coin-in (amounts wagered) for services related to the design, assembly, installation, operation, maintenance, and marketing of the WAP systems, as well as funding and administration of Company-sponsored progressive jackpots. Fees earned under gaming operations are recognized as revenue in the period earned and are classified as service revenue in the consolidated statement of operations when all of the criteria outlined above are met. Facilities management contracts Under facilities management contracts, the Company constructs, installs, operates and retains ownership of the online system. These contracts, principally in the North America Lottery segment, generally provide for a variable amount of monthly or weekly service fees paid to the Company directly from the customer based on a percentage of sales. Fees earned under facilities management contracts are recognized as revenue in the period earned, throughout the service period, and are classified as service revenue in the consolidated statement of operations when all of the criteria outlined above are met. Interactive Contracts Interactive revenues are principally generated from online social gaming and online real-money products and services (“IGTi”). Social gaming revenues are generated from the sale of virtual casino chips to players in the online DoubleDown Casino that can be used for additional play or game enhancements. Revenues from player purchases are recognized ratably over the estimated average service period in which the chips are consumed based on historical data analysis. Because DoubleDown is the principal, responsible for substantially all aspects of the casino services and sale of virtual goods to the player, revenues are recorded on a gross basis. Payment processing fees paid to Facebook, Apple and Google on a revenue participation basis are recorded within cost of services. IGTi revenues are generated from online real-money gaming solutions offerings, which encompass gaming systems infrastructure, applications, content licensing, and back office operational support services, including WAP jackpot funding and administration. IGTi solutions are generally provided under revenue sharing arrangements based on a percentage of net win similar to gaming operations discussed above. Post-Contract Customer Support (PCS) Product sales contracts generally include PCS, which includes telephone support, software maintenance, software support, professional services, and in some scenarios the right to receive unspecified upgrades/enhancements on a when-and-if-available basis. Fees earned under PCS contracts are generally recognized as revenue in the period earned (i.e., over the support period) and are classified as service revenue in the consolidated statement of operations when all of the criteria outlined above are met. Product Sales Product sales are derived from the following types of arrangements: Sale of Lottery Terminals and Sale of Gaming Machines, including Game Content These arrangements include the sale of gaming machines including game content, non-machine gaming related equipment, licensing and royalty fees, and component parts (including game themes and electronics conversion kits). The Company’s credit terms are predominantly short-term in nature. The Company also grants extended payment terms under contracts where the sale is secured by the related equipment sold. Revenue from the sale of lottery terminals and gaming machines is recognized based upon the contractual terms of each arrangement, but predominantly upon delivery or acceptance. If the sale of lottery terminals and gaming machines include multiple elements, these arrangements are accounted for under Multiple Element Accounting, discussed below. System Sales (Lottery and Gaming) System Sale arrangements typically include multiple elements, where the Company constructs, sells, delivers and installs a turnkey system (inclusive of point of sale terminals, if applicable) or delivers equipment and licenses the computer software for a fixed price, and the customer subsequently operates the system. System sale arrangements generally include customer acceptance provisions and general rights to terminate the contract if the Company is in breach of the contract. Such arrangements include non-software elements, software, professional services, and PCS in the form of maintenance and software support arrangements. Amounts due to the Company and costs incurred by the Company in implementing the system prior to customer acceptance are deferred. Revenue attributable to the system is classified as product sales in the consolidated statement of operations and is recognized upon customer acceptance as long as there are no substantial doubts regarding collectability. Revenues attributable to PCS provided subsequent to customer acceptance are classified as service revenue in the consolidated statement of operations in the period earned. Multiple Element Arrangements The Company uses multiple element guidance for both service arrangements and product sale arrangements. In some scenarios, all deliverables are considered one unit of accounting (i.e., facilities management contracts where the Company provides software as a service), while other arrangements contain multiple elements that can be separated into distinct deliverables. When arrangements contain multiple elements, including software and non-software components, the Company allocates revenue to each category based on a selling price hierarchy. Allocation of revenue to software and non-software components is based on either vendor-specific objective evidence ("VSOE") if available, third-party evidence ("TPE") if VSOE is not available, or best estimate of selling price ("BESP") if neither VSOE nor TPE is available. • VSOE of selling price is based on the net price charged when the element is sold separately. In determining VSOE, the Company requires that a substantial majority of the selling prices fall within a reasonable range based on historical discounting trends for specific products and services. VSOE for post-contract support and professional service hours may also be determined based on renewal rates, if available, provided that the renewal rates are substantive. • TPE of selling price is established by evaluating largely interchangeable competitor products or services in stand-alone sales to similar customers. However, as the Company’s products contain a significant element of proprietary technology and the Company’s solutions offer different features and functionality, the comparable pricing of third-party products with similar functionality typically cannot be obtained. • BESP is established considering multiple factors including, but not limited to, market conditions, competitive landscape, internal costs, and gross profit objectives. In some scenarios, contractual pricing may serve as the best estimate given the variability among jurisdictions and customers, while in other scenarios cost for each deliverable plus reasonable margin is used as management’s best estimate. In scenarios where the Company’s products include hardware containing required software that function together to provide the essential functionality of the product, the Company considers both the hardware and required software as “non-software deliverables” and has therefore concluded that such arrangements are not subject to the industry-specific software revenue recognition guidance. The Company recognizes revenue for these arrangements based on Accounting Standards Codification ("ASC") 605, Revenue Recognition , and allocates the arrangement consideration based on the relative selling price of the deliverables. In scenarios where the Company’s products include hardware where the software is not considered essential to the functionality of the hardware, the hardware revenue is recognized based on when the revenue recognition criteria is met (i.e., shipment, delivery and/or acceptance) and the software revenue is recognized under the software revenue recognition guidance provided under ASC 985, Software . If there are multiple deliverables within the software and non-software categories, revenue is first allocated between the software pool of deliverables and the non-software pool of deliverables on a relative fair value basis. Thereafter, revenue for each pool is further allocated as follows: • Non-software components: Revenue is further allocated to each separate unit of accounting using the relative selling prices of each deliverable in the priority order described above. However, revenue is only recognized if the unit of accounting has stand-alone value. A deliverable is considered to have stand-alone value if (a) it has value to the customer on stand-alone basis, and (b) if a general right of return exists relative to the delivered item, delivery or performance of the undelivered item is considered probable and substantially in the Company’s control. • Software components: If the arrangement contains more than one software deliverable, the arrangement consideration allocated to the software category as a group is then allocated to each software deliverable using VSOE, provided the deliverable has stand-alone value. If VSOE is not available for all deliverables, then the Company uses the residual method when VSOE of fair value of the undelivered items exists. If VSOE of one or more undelivered software items does not exist, then all the software deliverables are considered one unit of accounting. Revenue is deferred and recognized at the earlier of (i) delivery of those elements or (ii) when fair value can be established for the undelivered elements, unless PCS is the only undelivered element, in which case, the entire software category allocated consideration is recognized ratably over the service period.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents are composed of cash at banks and on-hand, and short-term highly liquid investments with a maturity of ninety days or less. Cash equivalents are stated at fair value.
Allowances for Trade Receivables and Customer Financing Receivables	Allowances for Trade Receivables and Customer Financing Receivables The Company maintains an allowance for credit losses for the estimated probable losses on uncollectible trade and customer financing receivables. The allowance is based upon the credit-worthiness of the Company’s customers, historical experience, the age of the receivable, as well as current market and economic conditions. Receivables are written off against these allowances in the period they are determined to be uncollectible. The Company’s customer financing receivables portfolio is composed of two classes, contracts and notes. Contracts include extended payment terms granted to qualifying customers for periods from one to five years and are typically secured by the related products sold. Notes consist of development financing loans granted to select customers to assist in the funding of new or expanding gaming facilities, generally under terms of one to seven years and are secured by the developed property and/or other customer assets. Customer financing interest income is recognized based on market rates prevailing at issuance.
Inventories	Inventories Inventories are stated at the lower of cost (under the first in, first out method) or market, not in excess of net realizable value.
Systems, Equipment and Other Assets Related to Contracts, Net and Property, Plant and Equipment, Net	Systems, Equipment and Other Assets Related to Contracts, Net and Property, Plant and Equipment, Net The Company has two principal types of fixed assets (collectively, “Fixed Assets”): • Systems, equipment and other assets relating to contracts (“Contract Assets”) principally composed of: ▪ Gaming assets ▪ Lottery assets • Property, plant and equipment (“Non-Contract Assets”) Contract Assets are assets that primarily support the Company’s operating contracts and facilities management contracts. Non-Contract Assets are assets the Company uses internally primarily in manufacturing, selling, general and administration, research and development and commercial service applications not associated with contracts. Fixed Assets are stated at cost, net of accumulated depreciation and accumulated impairment loss, if any. Depreciation commences upon placing the asset in service and is recognized on a straight-line basis over the estimated useful lives of the assets. The Company depreciates Fixed Assets over their estimated useful lives. The estimated useful life and salvage value are assigned to these assets based on historical information and future expectations. The estimated useful lives for Contract Assets depends on the type of actual cost, which is principally composed of three categories: • Lottery hard costs (for example: terminals, mainframe computers, communications equipment); and • Lottery soft costs (for example: software development costs represented by internal personnel costs); and • Commercial gaming machines. Lottery hard costs are depreciated over the base term of the contract plus extension years as defined in the contract, but generally not to exceed 10 years. Lottery soft costs are depreciated over the base term of the contract, but generally not to exceed 10 years. Commercial gaming machines are generally depreciated over three to five years. The estimated useful lives for property plant and equipment are generally 40 years for buildings and five to 10 years for furniture and equipment. Fixed Assets are derecognized upon disposal or when no future economic benefits are expected from the assets’ use or disposal. Any gain or loss arising on disposal of the asset (calculated as the difference between the net disposal proceeds and the carrying amount of the asset) is included in the consolidated statement of operations when the asset is derecognized. The residual values, useful lives and methods of depreciation are reviewed, at a minimum, at each financial year end and adjusted prospectively if appropriate. Fixed Assets carrying values are reviewed for impairment when events or changes in circumstances indicate that the carrying value may not be recoverable. Leasehold improvements are depreciated over the lesser of the remaining life of the lease or the estimated useful life of the improvement. Repair and maintenance costs, including planned maintenance, are expensed as incurred.
Research and Development and Capitalized Software Development Costs	Research and Development and Capitalized Software Development Costs Research and development (“R&D”) costs incurred prior to technological feasibility are expensed as incurred. R&D costs include salaries and benefits, stock-based compensation, consultants, facilities related costs, material costs, depreciation and travel. Costs incurred in the development of the Company’s externally-sold software products are expensed as incurred, except certain software development costs eligible for capitalization. Material software development costs incurred subsequent to establishing technological feasibility and through the general release of the software products are capitalized. Technological feasibility is demonstrated by the completion of a detailed program design or working model, if no program design is completed. Capitalized costs are amortized to cost of product sales over the products’ estimated economic life. Costs incurred in the development of software to be used only for services provided to customers are capitalized as internal-use software and amortized over the useful life to cost of services. Costs incurred in the development of software to be used only for internal use are capitalized as internal-use software and amortized over the useful life to selling, general and administrative expenses. Certain eligible costs incurred specific to customer contracts are deferred and amortized over the contracts’ estimated economic life as cost of services or product sales.
Jackpot Accounting	Jackpot Accounting The Company incurs jackpot expense and accrues jackpot liabilities with every wager on devices connected to a WAP system. Only WAP games include Company-sponsored jackpots for which the Company incurs jackpot expense. A portion of the fees paid to the Company is used for the funding and administration of Company-sponsored WAP jackpot payments. Jackpot expense represents the estimated cost to fund jackpots and is recorded to cost of services. Changes in estimates for WAP jackpot liabilities and expense are attributable to regular analysis and evaluation of the following factors: • Variations in slot play (frequency of WAP jackpots and patterns of coin-in driving WAP jackpot growth); • Volume (number of WAP units in service and levels of play or coin-in per unit); • Interest rate movements (higher rates cause lower jackpot expense; lower rates cause higher jackpot expense); and • Startup amount (the size of base WAP jackpots at initial setup or after a jackpot is won). The Company’s WAP jackpots are generally payable in equal annual installments over 20 to 26 years or immediately in the case of instant win systems. Winners may elect to receive a lump sum payment for the present value of the jackpot discounted at applicable interest rates in lieu of periodic annual installments. Discount rates eligible for use in the lump sum payment calculation vary by jurisdiction and are impacted by market forces and other economic conditions. Jackpot liabilities are composed of payments due previous winners, as well as amounts due future winners of WAP jackpots not yet won. Liabilities due previous winners for periodic payments are carried at the accreted cost of a qualifying U.S. government or agency annuity investment that may be purchased at the time of the jackpot win. If an annuity is subsequently sold and the periodic liability is instead guaranteed by surety bonds or letters of credit, the liability initially funded by an annuity continues to accrete at the same rate. If the periodic liability is not initially funded with an annuity investment, it is discounted and accreted using the risk-free rate (i.e., treasury rate) at the time of the jackpot win. Liabilities due future winners are recorded at the present value of the estimated amount of WAP jackpots not yet won. The Company estimates the present value of future winner liabilities using current market rates (prime, treasury, or agency, as applicable), weighted with historical lump sum payout election ratios. The most recent historical patterns indicate that approximately 90% of winners will elect the lump sum payment option. Additionally, the Company estimates the current portion of future winner liabilities based on historical experience with winner payment elections, in conjunction with the theoretical projected number of jackpots. Restricted Cash and Investments The Company is required by gaming regulation to maintain sufficient reserves in restricted cash accounts to be used for the purpose of funding payments to WAP jackpot winners. In certain cases regulators have allowed for surety bonds or letters of credit in lieu of restricted cash. Restricted amounts are based primarily on the WAP jackpot amount displayed to slot players and vary by jurisdiction. Compliance with restricted cash and investment or assurance requirements for jackpot funding is reported to gaming authorities in various jurisdictions. Additionally, restricted cash is maintained for interactive online player deposits, as well as collections on factored and serviced receivables not yet paid through to the third-party owner. Jackpot Annuity Investments In December 2015, the Company initiated a plan to sell jackpot annuity investments previously held-to-maturity for funding jackpot payments to previous winners, and instead satisfy funding assurance requirements through surety bonds or letters of credit where allowed by regulators. Accordingly, the remaining jackpot annuity investments, composed of discounted qualifying U.S. Treasury or agency securities, are classified as available-for-sale investments and carried at fair value with unrealized gain/loss recorded in other comprehensive income. WAP Systems Interest Interest income accretion on jackpot annuity investments is offset by interest expense accretion on previous winner liabilities. When the jackpot liability is funded by annuity investments, WAP interest income and expense accretes at approximately the same rate. When the jackpot liability is instead guaranteed by surety bonds or letters of credit and funded from operating cash flows, there is no WAP interest income accretion. WAP interest expense varies depending on the amount of jackpots won and the number of winners electing periodic payments. In addition to accretion, WAP interest income includes earnings on other cash and short-term investments held for WAP operations.
Advertising	Advertising Advertising costs are expensed as incurred. Advertising expense was $151.6 million , $130.1 million and $126.7 million for the years ended December 31, 2016 , 2015 and 2014 , respectively.
Contingencies	Contingencies The Company accounts for claims and contingencies in accordance with authoritative guidance that requires the Company to record an estimated loss from a claim or loss contingency when information available prior to issuance of the consolidated financial statements indicates that it is probable that a liability has been incurred at the date of the consolidated financial statements and the amount of the loss can be reasonably estimated. If the Company determines that it is reasonably possible but not probable that a liability has been incurred or if the amount of a probable loss cannot be reasonably estimated, then in accordance with the authoritative guidance, the Company discloses the amount or range of estimated loss if the amount or range of estimated loss is material. Accounting for claims and contingencies requires the Company to use judgment. The Company consults with legal counsel on those issues related to litigation and seeks input from other experts and advisors with respect to matters in the ordinary course of business. The Company expenses legal costs as incurred.
Redeemable non-controlling interests	Redeemable non-controlling interests Upon issuance, redeemable non-controlling interests are generally recorded at fair value. Subsequent to issuance redeemable non-controlling interests are reported at their redemption value no later than the date they become redeemable by the holder.
Income Taxes	Income Taxes Deferred tax liabilities and assets are recognized for the expected future tax consequences of events that have been included in the financial statements or tax returns. Deferred tax liabilities and assets are determined based on the difference between the tax basis of assets and liabilities and their reported amounts using enacted tax rates in effect for the year in which the differences are expected to reverse. Tax credits are generally recognized as reductions of income tax provisions in the year in which the credits arise. The measurement of deferred tax assets is reduced by a valuation allowance if, based upon available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The effect of a change in income tax rates is recognized as income or expense in the period that includes the enacted or substantively enacted date. Accounting for uncertainty in income taxes recognized in the consolidated financial statements is in accordance with accounting authoritative guidance, which prescribes a two-step process to determine the amount of tax benefit to be recognized. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon external examination. If the tax position is deemed “more-likely-than-not” to be sustained, the tax position is then assessed to determine the amount of benefit to recognize in the consolidated financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50 percent likelihood of being realized upon ultimate settlement. The Company recognizes interest and penalties related to unrecognized tax benefits on the provision for taxes line of the consolidated statement of operations. Accrued interest and penalties are included on the related tax liability line in the consolidated balance sheets. Deferred income taxes have not been provided on the majority of undistributed earnings of international subsidiaries as the majority of such earnings are indefinitely reinvested by the Company.
Earnings Per Share	Earnings Per Share Basic earnings per share of common stock is computed by dividing net income attributable to IGT PLC by the weighted-average number of common shares outstanding for the period. Diluted earnings per share of common stock is computed on the basis of the weighted-average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Dilutive potential common shares include outstanding stock options and restricted stock awards.
Concentrations of Risks	Concentrations of Risks Financial instruments that potentially subject the Company to concentration of credit risk consist principally of bank deposits, short and long-term investments, accounts receivable, customer financing receivables and foreign currency exchange contracts. Deposits held with banks in the United States may exceed the amount of Federal Deposit Insurance Corporation ("FDIC") insurance provided on such deposits. Deposits held with banks outside the United States generally do not benefit from FDIC insurance. The majority of the Company’s day-to-day banking operations globally are maintained with major, financially sound counterparties with high-grade credit ratings, and the Company limits its exposure to any one counterparty. The Company provides credit to customers in the normal course of business. Credit is extended to new customers based on checks of credit references, credit scores and industry reputation. Credit is extended to existing customers based on prior payment history and demonstrated financial stability. The credit risk associated with accounts receivable and customer financing receivables is generally limited due to the large number of customers and their geographic dispersion. The Company establishes an allowance for the estimated uncollectible portion of accounts receivable and customer financing receivables. Product sales are generally dispersed among a large number of customers, minimizing the reliance on any particular customer or group of customers. The counterparties to the Company’s foreign currency exchange contracts consist of a number of major financial institutions. In addition to limiting the amount of contracts the Company enters into with any one party, the Company monitors the credit quality of the counterparties on an ongoing basis. The Company purchases or licenses many sophisticated components and products from one or a limited number of qualified suppliers. If any of the Company’s suppliers were to cancel or materially change contracts or commitments with the Company or fail to meet the quality or delivery requirements needed to satisfy customer orders for the Company’s products, the Company could lose customer orders. The Company attempts to minimize this risk by finding alternative suppliers or maintaining adequate inventory levels.
Stock-Based Compensation	Stock-Based Compensation Stock-based compensation represents the cost related to stock-based awards granted to directors and employees. The Company measures stock-based compensation cost at the grant date, based on the estimated fair value of the award and recognizes the cost as expense, net of estimated forfeitures, over the vesting period. For awards that contain only a service vesting feature, the Company recognizes compensation cost on a straight-line basis over the awards’ vesting period. For awards with a performance condition, when achievement of the performance condition is deemed probable, the Company recognizes compensation cost on a graded-vesting basis over the awards’ expected vesting period.
New Accounting Standards	New Accounting Standards - Adopted In March 2016, the FASB issued Accounting Standards Update ("ASU") No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The amended guidance requires: (i) recognition of all excess tax expense or benefit in the consolidated statement of operations in the reporting period in which they occur; (ii) excess tax benefits to be classified along with other income tax cash flows as an operating activity in the statement of cash flows; (iii) cash paid by directly withholding shares for tax withholding purposes be classified as a financing activity in the statement of cash flows. The amended guidance also allows companies to repurchase more of an employee's vesting shares for tax withholding purposes without triggering liability accounting and to make an accounting policy election to either estimate the number of awards that are expected to vest, consistent with current GAAP, or account for forfeitures when they occur. The amended guidance is effective for the Company in the first quarter of 2017, with early adoption permitted in any interim or annual period. The amended guidance was early adopted in the fourth quarter of 2016, requiring the Company to reflect any adjustments to the consolidated statement of operations at January 1, 2016, the beginning of the annual period. The primary impact of adoption was the recognition of excess tax benefits in the provision for income taxes rather than additional paid-in capital for all periods in 2016. Additional amendments to the accounting for income taxes and minimum statutory withholding tax requirements had no impact to retained earnings at January 1, 2016, where the cumulative effect of these changes are required to be recorded. The Company elected to continue to estimate forfeitures expected to occur to determine the amount of compensation cost to be recognized in each period. The adoption of this guidance did not have a material effect on the Company's consolidated financial statements. In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40). The amended guidance defines management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. The amended guidance is effective for the Company in 2016, with early adoption permitted. The amended guidance was adopted in the fourth quarter of 2016 and did not have a material effect on the Company's consolidated financial statements or disclosures. New Accounting Standards - Not Yet Adopted In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment . The amended guidance simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. In accordance with the amended guidance, the Company will perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying value, and an impairment charge will be recognized for the amount by which the carrying value exceeds the reporting unit's fair value, not to exceed the total amount of goodwill allocated to that reporting unit. The amended guidance is effective for the Company in the first quarter of 2020 with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017, and must be applied prospectively. The Company is currently evaluating the impact and timing of adopting this guidance. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash . The amended guidance requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. As a result, amounts generally described as restricted cash and restricted cash equivalents should 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 amended guidance is effective for the Company in the first quarter of 2018 with early adoption permitted. The Company is currently evaluating the impact and timing of adopting this guidance. 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 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 the Company's operating leases, where the Company is the lessee, to be recognized on its consolidated balance sheet. The guidance requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The amended guidance is effective for the Company in the first quarter of 2019 with early adoption permitted. The Company is currently evaluating the impact and timing of adopting this guidance. In May 2014, the FASB issued ASU No. 2014-09 (Topic 606), Revenue from Contracts with Customers . The amended guidance, combined with all subsequent amendments (collectively "ASU 2014-09"), outlines a single comprehensive revenue model in accounting for revenue from contracts with customers. ASU 2014-09 supersedes existing revenue recognition guidance under GAAP, including industry-specific guidance, and replaces it with a five-step revenue model with a core principle to recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. Under ASU 2014-09, it is possible more judgment and estimates may be required within the revenue recognition process than required under existing GAAP, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price, and allocating the transaction price to each separate performance obligation. ASU 2014-09 is effective for the Company in the first quarter of 2018 using either of two methods: (i) retrospective to each prior reporting period presented with the option to elect certain practical expedients as defined within ASU 2014-09; or (ii) retrospective with the cumulative effect of initially applying ASU 2014-09 recognized at the date of initial application and providing certain additional disclosures as defined per ASU 2014-09. The Company is currently evaluating the method of adoption and impact of adopting this guidance, the effects of which are not currently reasonably estimable. Upon adoption, the Company anticipates increased revenue disclosures such as disclosures about variable consideration, contract assets, performance obligations, recognition over time versus at a point-in-time, and when the Company's customers control the goods or services delivered.
