Amounts billed prior to completing the earnings process are deferred until revenue recognition criteria are met.Gaming OperationsGaming operations revenues are generated from providing customers with our proprietary electronic gaming equipment and related network systems, licensing, and services under a variety of recurring revenue arrangements, including WAP, CDS, stand-alone participation and flat fee, equipment leasing and rental, and online gaming solutions.WAP systems consist of linked slot machines located in multiple casino properties, connecting to an IGT central computer system. WAP games differ from stand-alone units in that a progressive jackpot increases with every wager until a player wins the top award combination. Casinos with IGT WAP machines pay a percentage of the coin-in (amounts wagered) for IGT services related to the design, assembly, installation, operation, maintenance, and marketing of the WAP systems, as well as funding and administration of the progressive jackpot.Revenues from CDS, stand-alone and other equipment leasing or rentals are recognized based on a percentage of the net win or on a fixed daily/monthly fee or rental basis. Online gaming solutions encompass online casino gaming software and content licensing, as well as back office operational support services. All online gaming solutions are provided under revenue sharing arrangements based on a percentage of net win.Product SalesOur product sales revenues are generated from the sale of electronic gaming equipment and network systems, as well as licensing, services, and component parts. Time-based licensing and maintenance fees are typically recognized ratably over the term of the agreement. Our credit sales terms are predominately 90 days or less. We also grant extended payment terms under contracts of sale secured by the related equipment sold, and these contracts are typically paid within their terms.Our gaming machines and certain other tangible products, containing both software and nonsoftware components that function together to deliver the product's essential functionality, were previously subject to software revenue recognition rules. Under ASUs adopted for new and materially modified arrangements entered into after the beginning of our first quarter of fiscal 2010 (discussed below under Recently Issued Accounting Standards - Adopted), our gaming machines and certain other tangible products no longer fall under the scope of software revenue recognition rules and are generally recognized upon delivery and customer acceptance.Multi-element ArrangementsThe majority of our multiple element contracts are for some combination of machines, network systems, license fees, maintenance, training, and other services. Revenues for individual deliverables are recognized when the recognition criteria for that element has been met. We elected to early adopt ASUs for revenue recognition related to certain software-enabled products and multi-element arrangements on a prospective basis for new or materially modified arrangements entered into after the beginning of fiscal 2010.Most of our products and services qualify as separate units of accounting, and the ASUs did not change this premise. The terms of performance, cancellation, termination, or refunds in our multiple element contracts are similar to those for individual stand-alone deliverables. Under the ASUs, arrangement consideration is allocated among multiple deliverables based on relative selling prices. In order of preference, relative selling prices are estimated based on VSOE, third-party evidence, or management's best estimate, and the residual method is not allowed for nonsoftware elements.VSOE is determined by the net price charged for each deliverable when it is sold separately. VSOE for maintenance agreements is determined based on actual renewals sold. Third-party evidence is generally not available for our products.When VSOE is not available, generally for new or highly customized offerings, the estimated selling price is the amount we would sell the product or service for individually. Management's best estimate is made based on our standard pricing and discounting practices, which consider multiple factors, such as market conditions, competitive landscape, internal costs, and profit objectives.Under the ASUs, revenues for machines and other software-enabled equipment in certain bundled arrangements are no longer deferred because VSOE is not available for an undelivered element. Generally, revenues allocated to nonsoftware elements will be recognized upon delivery and customer acceptance, and only revenues allocated to software elements could require deferral and recognition over a lease or license term.Prior to the beginning of fiscal 2010, if we were unable to establish VSOE for any undelivered element, revenue was generally deferred until all elements were delivered or until VSOE could be determined. If we did not have VSOE for a delivered element, VSOE for the undelivered elements was deferred, and the residual amount constituted the revenues recognized for the delivered elements. Additionally, when machines were sold in combination with a leased system on which the machines depend for essential functionality, machine revenues were recognized ratably over the system lease contract term.Deferred RevenueDeferred revenue consists of amounts received or billed after products are delivered or services are rendered, but prior to meeting all of the requirements for revenue recognition. Complex systems and/or multi-element contracts may take several months to complete and our deferred revenues may increase as our products evolve toward a more systems-centric environment.Deferred revenue balances in the table below related primarily to product sales where the installation was not yet complete or we were obligated to perform future services. At September 30, 2010, $18.6 remains deferred because it is subject to prior revenue recognition criteria in effect before the beginning of fiscal 2010.Revenue RecognitionWe recognize revenues when all of the following have been satisfied:persuasive evidence of an arrangement existsthe price to the customer isfalsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringDescribes an entity's accounting policy for revenue recognition.

A portion of the casino fees paid to IGT is used for the funding and administration of WAP jackpot payments. Jackpot expense represents the estimated cost to fund jackpots and is recorded within the cost of gaming operations. Changes in estimated amounts for WAP jackpot liabilities and associated jackpot expense are attributable to regular analysis and evaluation of variations in slot play (frequency of WAP jackpots and patterns of coin-in driving jackpot growth), volume (number of WAP units in service and levels of coin-in per unit), interest or discount rate movements, and the size of base WAP jackpots (startup amount) at initial setup or after a WAP win.Our 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 comprised of payments due previous winners, as well as amounts due future winners of WAP jackpots not yet won. Previous winner liabilities for periodic payments are carried at the accreted cost of jackpot annuity investments in qualifying US government or agency securities used to fund future periodic payments. Liabilities due future winners are revalued and recorded at the present value of the amount carried on WAP meters for jackpots not yet won.We estimate the present value of future winner liabilities using current market prime, treasury, or agency rates, 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, we estimate the current portion of future winner liabilities based on historical experience with winner payment elections, in conjunction with the theoretical projected number of jackpots.Jackpot AccountingJackpot Liabilities and ExpenseWe incur jackpot expense and accrue jackpot liabilities with every wager on a device connected to an IGT WAPfalsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringDescription of accounting policy for jackpot liabilities and expenses.No authoritative reference available.falsefalseJackpot Accounting Policy [Textblock]5false0us-gaap_CashAndCashEquivalentsRestrictedCashAndCashEquivalentsPolicyus-gaaptruenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalselabel1falsefalsefalse00Restricted Cash and InvestmentsWe are required by gaming regulation to maintain sufficient reserves in restricted accounts to be used for the purpose of funding payments to WAP jackpot winners.

An entity shall disclose its policy for determining which items are treated as cash equivalents, including (1) the nature of any restrictions on the entity's use of its cash and cash equivalents, (2) whether the entity's cash and cash equivalents are insured or expose the entity to credit risk, (3) the classification of any negative balance accounts (overdrafts), and (4) the carrying basis of cash equivalents (for example, at cost) and whether the carrying amount of cash equivalents approximates fair value. Cash includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the customer may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. In addition, cash equivalents include short-term, highly liquid investments that are both readily convertible to known amounts of cash and so near their maturity that they present insignificant risk of changes in value because of changes in interest rates. Restrictions may include legally restricted deposits held as compensating balances against short-term borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits; however, time deposits and short-term certificates of deposit are not generally included in legally restricted deposits.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Regulation S-X (SX) -Number 210 -Section 02 -Paragraph 1 -Article 5 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Financial Reporting Release (FRR) -Number 203 -Paragraph 02-03 Reference 3: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Regulation S-X (SX) -Number 210 -Section 03 -Paragraph 1 -Subparagraph a -Article 9 falsefalseCash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy6false0us-gaap_MarketableSecuritiesHeldToMaturitySecuritiesPolicyus-gaaptruenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalselabel1falsefalsefalse00Jackpot Annuity InvestmentsThese investments are comprised of discounted qualifying US treasury or agency securities purchased and held to maturity to fund annual jackpot payments due previous winners.

We use historical data and projections to estimate expected employee behaviors related to option exercise and forfeitures. We expense share-based compensation over the applicable vesting period using the straight-line method for service-based awards and the accelerated method for performance-based awards. Compensation for share-based awards granted prior to the beginning of fiscal 2006 was recognized under the accelerated method. See Note 6.The fair value of restricted share awards is based on the market price of IGT stock on the grant date. We estimate the fair value of each stock option award on the grant date using the Black-Scholes valuation model. Option valuation models require the input of highly subjective assumptions, and changes in assumptions used can materially affect the fair value estimate. Expected volatility and dividends are based on implied and historical IGT stock factors. Expected term represents the estimated weighted average time between grant and employee exercise.

We enter into derivative financial instruments with high credit quality counterparties and diversify our positions among such counterparties to reduce our exposure to credit losses.We recognize derivative financial instruments as fair value assets or liabilities. Accounting for changes in the fair value of derivatives depends on the intended use and resulting designation. We are not party to leveraged derivatives and do not hold or issue financial instruments for speculative purposes. We record derivative financial instruments on a net basis with counterparties for which a master netting arrangement has been executed. Unless otherwise noted, derivative gains or losses, including any ineffectiveness, are recognized in other income (expense). See Note 19.Foreign Currency HedgingWe routinely use derivative financial instruments to minimize our market risk exposure related to our monetary assets and liabilities denominated in nonfunctional foreign currencies. The primary business objective of our hedging program is to minimize the impact to earnings from changes in foreign exchange rates. These hedging instruments are subject to fluctuations in value that are generally offset by the value of the underlying exposures being hedged. Counterparties to our agreements are major commercial banks. These forward exchange contracts are not designated hedges.We hedge significant investments denominated in foreign currency with forward exchange contracts to protect the US dollar value of our investment. These forward exchange contracts are designated fair value hedges. These derivative gains or losses are recorded together with the offsetting gains or losses on the change in the investment's fair value attributable to foreign currency rates. Time value is excluded from effectiveness testing.Interest Rate ManagementWe use interest rate swap derivatives to diversify our debt portfolio between fixed and variable rate instruments. The amount and term of each swap is matched with all or a portion of outstanding principal and remaining term of a specific obligation. Our swaps exchange fixed rates for variable rates without an exchange of the notional amount upon which they are based.These swaps are designated fair value hedges because they protect us against fair value changes related to interest rates on a portion of our fixed rate borrowings. These derivative gains or losses are recorded together with the offsetting change in the fair value of the hedge-designated portion of fixed rate debt. Amounts receivable or payable under the swaps are net settled and recorded as a net receivable or payable with corresponding adjustments to interest expense.DerivativesWe use derivative financial instruments to manage certain foreign currency exchange and interest rate risk.

We adopted this new fair value definition and framework for non-financial assets and liabilities at the beginning of fiscal 2010.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. Assets and liabilities carried at fair value are classified and disclosed in one of the following three categories:Level 1 - Quoted market prices in active markets for identical instrumentsLevel 2 - Quoted market prices for similar instruments, using observable market based inputs or unobservable inputs corroborated by market dataLevel 3 - Unobservable inputs using our own assumptions when observable inputs are unavailableThe fair value of our financial assets and liabilities are described in more detail in Note 20, along with valuation methods and assumptions used to estimate fair value when quoted market prices are not available.

Under these ASUs, tangible products, containing both software and nonsoftware components that function together to deliver a tangible product's essential functionality, are no longer subject to software revenue accounting. These ASUs also established a more economically aligned model for allocating revenues among deliverables in a multi-element arrangement, based on relative selling prices.We elected to early adopt these ASUs prospectively for new or materially modified arrangements entered into on or after the beginning of our fiscal 2010. See our revenue recognition accounting policies above for additional information about our application of these ASUs. The table below reflects pro forma revenues that would have been reported under the prior accounting guidance and the incremental revenues recognized during fiscal 2010 that would have been recognized in other periods under the prior guidance. AsReported ProForma Increase(decrease) (In s) Revenues Gaming operations $ 1,101.0 $ 1,094.1 $ 6.9 Product Sales 886.2 846.7 39.5 Total $ 1,987.2 $ 1,940.8 $ 46.4 Fair Value MeasurementsIn fiscal 2010 for non-financial assets and liabilities and fiscal 2009 for financial assets and liabilities, we adopted an accounting standard issued in September 2006 that established a universal definition and framework for measuring fair value with expanded disclosures.In the second quarter of fiscal 2010, we adopted an ASU issued in January 2010 requiring additional disclosures related to assets and liabilities carried at fair value to identify significant transfers between Level 1 and Level 2, techniques and inputs used, and any significant changes to techniques and inputs (see Note 20).The adoption of these accounting standards did not have a material impact on our results of operations, financial position or cash flows.Participating Securities in Share-Based Payment TransactionsAt the beginning of fiscal 2010, we adopted an ASU issued in June 2008 for determining whether instruments granted in share-based payment transactions are participating securities that should be included in the computation of EPS using the two-class method (see Note 18.) Certain restricted stock granted under our employee SIP (see Note 6) is considered a participating security because it carries non-forfeitable rights to dividends. This adoption did not have a material impact on our financial statements and the effect of the required retrospective application is summarized in the table at the top of this section.Business Combinations and Noncontrolling Interests (NCI)At the beginning of fiscal 2010, we adopted accounting standards issued in December 2007 revising the method of accounting for a number of aspects for business combination and NCI (i.e. minority interests), such that more assets and liabilities will be measured at fair value as of the acquisition date. Certain contingent consideration liabilities will require remeasurement at fair value in each subsequent reporting period. NCI will initially be measured at fair value and classified as a separate component of equity.Acquisition related costs, such as fees for attorneys, accountants, and investment bankers, will be expensed as incurred and no longer be capitalized as part of the business purchase price. For all acquisitions, regardless of the consummation date, deferred tax assets and uncertain tax position adjustments occurring after the measurement period will be recorded as a component of income tax expense, rather than adjusted through goodwill. For business combinations and asset purchases, the impact of this guidance on our results of operations or financial position will vary depending on the specifics of each transaction.This adoption did not have a material impact on our consolidated financial position, results of operations or cash flows. Income attributable to NCI has been presented as a component of other income (expense) as it was not significant to our consolidated operating results. The required retrospective reclassification of NCI from other liabilities to a separate component of equity is summarized in the table at the top of this section.Convertible Debt InstrumentsAt the beginning of fiscal 2010, we adopted an ASU issued in May 2008 requiring the separation of liability (debt) and equity (conversion option) components for convertible debt instruments that may settle in cash upon conversion to reflect an effective nonconvertible borrowing rate when the debt was issued. We estimated the fair value of our convertible debt (see Note 13) using similar debt instruments at issuance that did not have a conversion feature and allocated the residual fair value to an equity component that represents the estimated fair value of the conversion feature at issuance.This ASU was retrospectively applied for all outstanding convertible debt and the adjustments are summarized in the table at the top of this section.

An entity shall disclose its policy for determining which items are treated as cash equivalents. Other information that may be disclosed includes (1) the nature of any restrictions on the entity's use of its cash and cash equivalents, (2) whether the entity's cash and cash equivalents are insured or expose the entity to credit risk, (3) the classification of any negative balance accounts (overdrafts), and (4) the carrying basis of cash equivalents (for example, at cost) and whether the carrying amount of cash equivalents approximates fair value. Cash includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the customer may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. In addition, cash equivalents include short-term, highly liquid investments that are both readily convertible to known amounts of cash and so near their maturity that they present insignificant risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three-years ago does not become a cash equivalent when its remaining maturity is three months. For a bank, may include explanation and amount of requirement to maintain reserves against deposits.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Financial Reporting Release (FRR) -Number 203 -Paragraph 02-03 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Regulation S-X (SX) -Number 210 -Section 02 -Paragraph 1 -Article 5 Reference 3: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Statement of Financial Accounting Standard (FAS) -Number 95 -Paragraph 7, 8, 9, 10 Reference 4: http://www.xbrl.org/2003/role/presentationRef -Publisher AICPA -Name Technical Practice Aid (TPA) -Number 2110 -Paragraph 6 falsefalseCash and Cash Equivalents, Policy [Text Block]23false0us-gaap_InvestmentPolicyTextBlockus-gaaptruenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalselabel1falsefalsefalse00Investment SecuritiesAvailable-for-sale securities are reported at fair value, with unrealized gains and losses recorded in accumulated other comprehensive income (loss).
