Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation Description of Business Expedia Group, Inc. and its subsidiaries provide travel products and services to leisure and corporate travelers in the United States and abroad as well as various media and advertising offerings to travel and non-travel advertisers. These travel products and services are offered through a diversified portfolio of brands including: Brand Expedia®, Hotels.com®, Expedia® Partner Solutions, Vrbo®, Egencia®, trivago®, Orbitz®, Travelocity®, Hotwire®, Wotif®, ebookers®, CheapTickets®, Expedia Group™ Media Solutions, CarRentals.com™, Expedia Cruises TM , Traveldoo®, and VacationRentals.com. In addition, many of these brands have related international points of sale. We refer to Expedia Group, Inc. and its subsidiaries collectively as “Expedia Group,” the “Company,” “us,” “we” and “our” in these consolidated financial statements. COVID-19 During 2020, the COVID-19 pandemic severely restricted the level of economic activity around the world, and, is continuing to have an unprecedented effect on the global travel industry. The various government measures implemented to contain the COVID-19 pandemic, such as imposing restrictions on travel and business operations and advising or requiring individuals to limit or forgo their time outside of their homes, initially led to unprecedented levels of cancellations and continues to have a negative impact on the number of new travel bookings. While many countries have continued vaccinating their residents against COVID-19 during 2021, vaccine hesitancy as well as uncertainty over the impact of the delta or other new variants of the virus, including the efficacy of the vaccines against such variants, has contributed, and may continue to contribute to, delays in economic recovery. Overall, the full duration and total impact of COVID-19 remains uncertain and it is difficult to predict how the recovery will unfold for the travel industry and, in particular, our business, going forward. Basis of Presentation These accompanying financial statements present our results of operations, financial position and cash flows on a consolidated basis. The unaudited consolidated financial statements include Expedia Group, Inc., our wholly-owned subsidiaries, and entities we control, or in which we have a variable interest and are the primary beneficiary of expected cash profits or losses. We have eliminated significant intercompany transactions and accounts. We have prepared the accompanying unaudited consolidated financial statements in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial reporting. We have included all adjustments necessary for a fair presentation of the results of the interim period. These adjustments consist of normal recurring items. Our interim unaudited consolidated financial statements are not necessarily indicative of results that may be expected for any other interim period or for the full year. These interim unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2020, previously filed with the Securities and Exchange Commission (“SEC”). trivago is a separately listed company on the Nasdaq Global Select Market and, therefore is subject to its own reporting and filing requirements, which could result in possible differences that are not expected to be material to Expedia Group. Accounting Estimates We use estimates and assumptions in the preparation of our interim unaudited consolidated financial statements in accordance with GAAP. Our estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of our interim unaudited consolidated financial statements. These estimates and assumptions also affect the reported amount of net income or loss during any period. Our actual financial results could differ significantly from these estimates. The significant estimates underlying our interim unaudited consolidated financial statements include revenue recognition; recoverability of current and long-lived assets, intangible assets and goodwill; income and transactional taxes, such as potential settlements related to occupancy and excise taxes; loss contingencies; deferred loyalty rewards; acquisition purchase price allocations; stock-based compensation; accounting for derivative instruments and provisions for credit losses, customer refunds and chargebacks. The COVID-19 pandemic has created and may continue to create significant uncertainty in macroeconomic conditions, which may cause further business disruptions and adversely impact our results of operations. As a result, many of our estimates and assumptions required increased judgment and carry a higher degree of variability and volatility. As events continue to evolve and additional information becomes available, our estimates may change materially in future periods. Reclassifications We have reclassified prior period financial statements to conform to the current period presentation. During the first quarter of 2021, we centralized the management of our licensing and maintenance costs and reclassified certain expenses to technology and content expense from within our other operating expense line items on our consolidated statements of operations. The following table presents a summary of the amounts as reported and as reclassified in our consolidated statements of operations for the three and nine months ended September 30, 2020: Three months ended Nine months ended As reported As reclassified As reported As reclassified (In millions) Cost of revenue $ 375 $ 363 $ 1,393 1,373 Selling and marketing 529 525 2,035 2,021 Technology and content 224 242 787 828 General and administrative 134 132 473 466 Seasonality We generally experience seasonal fluctuations in the demand for our travel services. For example, traditional leisure travel bookings are generally the highest in the first three quarters as travelers plan and book their spring, summer and winter holiday travel. The number of bookings typically decreases in the fourth quarter. Because revenue for most of our travel services, including merchant and agency hotel, is recognized as the travel takes place rather than when it is booked, revenue typically lags bookings by several weeks for our hotel business and can be several months or more for our alternative accommodations business. Historically, Vrbo has seen seasonally stronger bookings in the first quarter of the year, with the relevant stays occurring during the peak summer travel months. The seasonal revenue impact is exacerbated with respect to income by the nature of our variable cost of revenue and direct sales and marketing costs, which we typically realize in closer alignment to booking volumes, and the more stable nature of our fixed costs. Furthermore, operating profits for our primary advertising business, trivago, have typically been experienced in the second half of the year, particularly the fourth quarter, as selling and marketing costs offset revenue in the first half of the year as we typically increase marketing during the busy booking period for spring, summer and winter holiday travel. As a result on a consolidated basis, revenue and income are typically the lowest in the first quarter and highest in the third quarter. The growth of our international operations, advertising business or a change in our product mix, including the growth of Vrbo, may influence the typical trend of the seasonality in the future.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Recently Adopted Accounting Policies Simplifying the Accounting for Income Taxes. As of January 1, 2021, we adopted the Accounting Standards Updates (“ASU”) guidance to simplify the accounting for income taxes. This new standard eliminated certain exceptions in current guidance related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period, and the recognition of deferred tax liabilities for outside basis differences. It also clarified and simplified other aspects of the accounting for income taxes. The adoption of this new guidance did not have a material impact on our consolidated financial statement s . Investments - equity securities; Investments - Equity Method and Joint Ventures; Derivatives and Hedging. As of January 1, 2021, we adopted the new ASU guidance which clarified the interaction between the accounting for investments in equity securities, equity method investments and certain derivative instruments. The adoption of this new guidance did not have a material impact on our consolidated financial statement s . Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. As of January 1, 2021, we adopted the new ASU guidance which simplified the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. Specifically, the standard simplified accounting for convertible instruments by removing major separation models required under current GAAP, removing certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, which permitted more equity contracts to qualify for it, and simplified the diluted earnings per share calculation in certain areas. The adoption of this new guidance did not have a material impact on our consolidated financial statement s . The convertible senior notes issued in February 2021 are accounted for in accordance with this new guidance. See Note 4 – Debt for additional information. Significant Accounting Policies Below are the significant accounting policies with interim disclosure requirements. For a comprehensive description of our accounting policies, refer to our Annual Report on Form 10-K for the year ended December 31, 2020. Revenue Prepaid Merchant Bookings. We classify payments made to suppliers in advance of Vrbo performance obligations as prepaid merchant bookings included within prepaid and other current assets. Prepaid merchant bookings was $591 million as of September 30, 2021 and $389 million as of December 31, 2020. Deferred Merchant Bookings. We classify cash payments received in advance of our performance obligations as deferred merchant bookings. At December 31, 2020, $2.3 billion of advance cash payments was reported within deferred merchant bookings, $1.6 billion of which was recognized resulting in $292 million of revenue during the nine months ended September 30, 2021. At September 30, 2021, the related balance was $5.1 billion. At December 31, 2020, $769 million of deferred loyalty rewards was reported within deferred merchant bookings, $394 million of which was recognized within revenue during the nine months ended September 30, 2021. At September 30, 2021, the related balance was $790 million. Deferred Revenue. At December 31, 2020, $172 million was recorded as deferred revenue, $97 million of which was recognized as revenue during the nine months ended September 30, 2021. At September 30, 2021, the related balance was $161 million. Practical Expedients and Exemptions. We have used the portfolio approach to account for our loyalty points as the rewards programs share similar characteristics within each program in relation to the value provided to the traveler and their breakage patterns. Using this portfolio approach is not expected to differ materially from applying the guidance to individual contracts. However, we will continue to assess and refine, if necessary, how a portfolio within each rewards program is defined. We do not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed. Cash, Restricted Cash and Cash Equivalents Our cash and cash equivalents include cash and liquid financial instruments, including money market funds and term deposit investments, with maturities of three months or less when purchased. Restricted cash includes cash and cash equivalents that is restricted through legal contracts, regulations or our intention to use the cash for a specific purpose. Our restricted cash primarily relates to certain traveler deposits and to a lesser extent collateral for office leases. The following table reconciles cash, cash equivalents and restricted cash reported in our consolidated balance sheets to the total amount presented in our consolidated statements of cash flows: September 30, December 31, (in millions) Cash and cash equivalents $ 5,031 $ 3,363 Restricted cash and cash equivalents 1,587 772 Restricted cash included within long-term investments and other assets — 3 Total cash, cash equivalents and restricted cash and cash equivalents in the consolidated statement of cash flow $ 6,618 $ 4,138 Accounts Receivable and Allowances Accounts receivable are generally due within thirty days and are recorded net of an allowance for expected uncollectible amounts. We consider accounts outstanding longer than the contractual payment terms as past due. The risk characteristics we generally review when analyzing our accounts receivable pools primarily include the type of receivable (for example, credit

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Financial assets and liabilities measured at fair value on a recurring basis as of September 30, 2021 are classified using the fair value hierarchy in the table below: Total Level 1 Level 2 (In millions) Assets Cash equivalents: Money market funds $ 79 $ 79 $ — Mutual funds 23 23 — Term deposits 276 — 276 Investments: Marketable equity securities 115 115 — Total assets $ 493 $ 217 $ 276 Liabilities Derivatives: Foreign currency forward contracts $ 2 $ — $ 2 Financial assets measured at fair value on a recurring basis as of December 31, 2020 are classified using the fair value hierarchy in the table below: Total Level 1 Level 2 (In millions) Assets Cash equivalents: Money market funds $ 147 $ 147 $ — Term deposits 49 — 49 U.S. treasury securities 150 150 — Investments: Term deposits 24 — 24 Marketable equity securities 123 123 — Total assets $ 493 $ 420 $ 73 Liabilities Derivatives: Foreign currency forward contracts $ 14 $ — $ 14 We classify our cash equivalents and investments within Level 1 and Level 2 as we value our cash equivalents and investments using quoted market prices or alternative pricing sources and models utilizing market observable inputs. Valuation of the foreign currency forward contracts is based on foreign currency exchange rates in active markets, a Level 2 input. As of September 30, 2021 and December 31, 2020, our cash and cash equivalents consisted primarily of U.S. treasury securities, term deposits and mutual funds with maturities of three months or less and bank account balances. We hold term deposit investments with financial institutions. Term deposits with original maturities of less than three months are classified as cash equivalents and those with remaining maturities of less than one year are classified within short-term investments. Our marketable equity securities consist of our investment in Despegar, a publicly traded company, which is included in long-term investments and other assets in our consolidated balance sheets. During the nine months ended September 30, 2021 and 2020, we recognized a loss of approximately $7 million and approximately $68 million within other, net in our consolidated statements of operations related to the fair value changes of this equity investment. Derivative instruments are carried at fair value on our consolidated balance sheets. We use foreign currency forward contracts to economically hedge certain merchant revenue exposures, foreign denominated liabilities related to certain of our loyalty programs and our other foreign currency-denominated operating liabilities. Our goal in managing our foreign exchange risk is to reduce, to the extent practicable, our potential exposure to the changes that exchange rates might have on our earnings, cash flows and financial position. Our foreign currency forward contracts are typically short-term and, as they do not qualify for hedge accounting treatment, we classify the changes in their fair value in other, net. As of September 30, 2021, we were party to outstanding forward contracts hedging our liability and revenue exposures with a total net notional value of $2.8 billion. We had a net forward liability of $2 million ($24 million gross forward liability) as of September 30, 2021 and $14 million ($23 million gross forward liability) as of December 31, 2020 recorded in accrued expenses and other current liabilities. We recorded $15 million and $(1) million in net gains (losses) from foreign currency forward contracts during the three months ended September 30, 2021 and 2020 as well as $(8) million and $99 million in net gains (losses) from foreign currency forward contracts during the nine months ended September 30, 2021 and 2020. Assets Measured at Fair Value on a Non-recurring Basis Our non-financial assets, such as goodwill, intangible assets and property and equipment, as well as equity method investments, are adjusted to fair value when an impairment charge is recognized or the underlying investment is sold. Such fair value measurements are based predominately on Level 3 inputs. We measure our minority investments that do not have readily determinable fair values at cost less impairment, adjusted by observable price changes with changes recorded within other, net on our consolidated statements of operations. Goodwill . During 2020, due to the severe and persistent negative effect COVID-19 had on global economies, the travel industry and our business, as well as the uncertainty and high variability in anticipated versus actual rates of recovery, in addition to our annual assessment on October 1, 2020, we deemed it necessary to perform various interim assessments of goodwill. As a result of assessments during the nine months ended September 30, 2020, we recognized goodwill impairment charges of $799 million, of which $559 million related to our Retail segment, primarily our Vrbo reporting unit, and $240 million related to our trivago segment. Our assessment compared the fair value of the reporting units to their carrying value. The fair value estimates for all reporting units, except trivago, were based on a blended analysis of the present value of future discounted cash flows and market value approach, Level 3 inputs. The significant estimates used in the discounted cash flows model included our weighted average cost of capital, projected cash flows and the long-term rate of growth. Our assumptions were based on the actual historical performance of the reporting unit and took into account operating result trends, the anticipated duration of COVID-19 impacts and rates of recovery, and implied risk premiums based on market prices of our equity and debt as of the assessment dates. Our significant estimates in the market approach model included identifying similar companies with comparable business factors such as size, growth, profitability, risk and return on investment and assessing comparable revenue and earnings multiples in estimating the fair value of the reporting unit. The fair value estimate for the trivago reporting unit was based on trivago’s stock price, a Level 1 input, adjusted for an estimated control premium. The excess of the reporting unit's carrying value over our estimate of the fair value was recorded as goodwill impairment charges during 2020. As of December 31, 2020, the applicable reporting units within our Retail segment had $2.3 billion goodwill remaining after the impairments incurred in 2020 and our trivago segment had $337 million goodwill remaining. Intangible Assets. During the nine months ended September 30, 2020, we recognized intangible asset impairment charges of $172 million within our Retail segment primarily related to indefinite-lived trade names that resulted from changes in estimated future revenues of the related brands and, to a lesser extent, supplier relationship assets that were entirely written off in connection with a decision to streamline a smaller brand as well as intangible assets related to held-for-sale assets. The indefinite-lived assets, classified as Level 3 measurements, were valued using the relief-from-royalty method, which includes unobservable inputs, including royalty rates and projected revenues. The full duration and total impact of COVID-19 remains uncertain and it is difficult to predict how the recovery will continue to unfold (in general and versus our expectations) for global economies, the travel industry or our business. Additionally, as the stock of our trivago segment is publicly traded, it is difficult to predict market dynamics and the extent or

Long-term Debt Extinguishment of Debt. During the nine months ended September 30, 2021, we used the net proceeds from the February and March 2021 private placements discussed below, to (i) finance a redemption of all of our outstanding 7.0% senior notes due 2025 (the “7.0% Notes”), (ii) finance a tender offer for a portion of our issued and outstanding 6.25% senior notes due 2025 (the “6.25% Notes”) and (iii) to pay fees and expenses related to the foregoing. On March 3, 2021, we completed the redemption of all of our outstanding 7.0% Notes as well as settled the tender offer to purchase $956 million in aggregate principal of our 6.25% Notes, which resulted in the recognition of a loss on debt extinguishment of $280 million during the nine months ended September 30, 2021. This loss primarily reflected the payment of early payment premiums and fees associated with the tender offer as well as the write-off of unamortized debt issuance costs. The cash payments related to the debt extinguishment were classified as cash outflows from financing activities on the consolidated statement of cash flows and were $258 million during the nine months ended September 30, 2021, which reflected the $280 million loss on debt extinguishment adjusted for the non-cash write-off of debt issuance costs of approximately $23 million. In addition, we paid accrued and unpaid interest on the 7.0% and tendered portion of the 6.25% Notes up to the date of settlement. February 2021 Convertible Senior Notes Private Placement. On February 19, 2021, we completed our private placement of $1 billion aggregate principal amount of unsecured 0% convertible senior notes due 2026 (the “Convertible Notes”). The net proceeds from the issuance of the Convertible Notes was approximately $983 million after deducting debt issuance costs. The Convertible Notes are unsecured, unsubordinated obligations and rank equally in right of payment with each other and with all of our existing and future unsecured and unsubordinated obligations, including our existing senior notes. The Convertible Notes are fully and unconditionally guaranteed by the subsidiary guarantors, which include each domestic subsidiary that is a borrower under or guarantees the obligations under our existing senior secured credit agreement. So long as the guarantees are in effect, each subsidiary guarantor’s guarantee will be the unsecured, unsubordinated obligation of such subsidiary guarantor and will rank equally in right of payment with each other and with all of such subsidiary guarantor’s existing and future unsecured and unsubordinated obligations, including such subsidiary guarantor’s guarantees of our existing senior notes. The Convertible Notes will mature on February 15, 2026, unless earlier converted, redeemed or repurchased. The Convertible Notes will not bear regular interest, and the principal amount of the Convertible Notes will not accrete. The Convertible Notes have an initial conversion rate of 3.9212 shares of common stock of Expedia Group with a par value $0.0001 per share (referred to as “our common stock” herein), per $1,000 principal amount of Convertible Notes, which is equal to an initial conversion price of approximately $255.02 per share of our common stock. The conversion rate is subject to adjustment from time to time upon the occurrence of certain events, including, but not limited to, the issuance of stock dividends and payment of cash dividends. At any time prior to the close of business on the business day immediately preceding November 15, 2025, holders may convert their Convertible Notes at their option only under the following circumstances: • during any calendar quarter commencing after the calendar quarter ending on March 31, 2021 (and only during such calendar quarter), if the last reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is equal to or greater than 130% of the conversion price then in effect on each applicable trading day; • during the five five • if the Company calls any or all of the Convertible Notes for redemption, at any time prior to the close of business on the business day immediately prior to the redemption date, but only with respect to the Convertible Notes called for redemption (or deemed called for redemption); or • upon the occurrence of specified corporate events. Irrespective of the foregoing conditions, holders may convert their Convertible Notes on or after November 15, 2025 and prior to the close of business on the second scheduled trading day immediately preceding the maturity date. Additionally, upon the occurrence of a corporate event that constitutes a “make-whole fundamental change” per the indenture, or if we call the Convertible Notes for redemption, and a holder elects to convert its Convertible Notes in connection with such make-whole fundamental change or during the related redemption period, as the case may be, such holder may be entitled to an increase in the conversion rate in certain circumstances as described in the indenture. Upon conversion, holders will receive cash, shares of our common stock or a combination of cash and shares of our common stock, at our election. We may not redeem the Convertible Notes prior to February 20, 2024. On or after February 20, 2024 and prior to the 41st scheduled trading day immediately preceding the maturity date, if the last reported sale price per share of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption, we may redeem for cash all or part of the Convertible Notes at a redemption price equal to 100% of the principal amount of the Convertible Notes to be redeemed, plus accrued and unpaid special interest, if any, to, but excluding, the redemption date, except as otherwise described in the indenture. The net carrying amount of the Convertible Notes as of September 30, 2021 was $985 million, which reflects the $1 billion in principal less unamortized debt issuance costs of $15 million. Interest expense related to the amortization of the debt issuance costs for the Convertible Notes was $2 million during the nine months ended September 30, 2021. March 2021 Senior Note Private Placement. On March 3, 2021, we privately placed $1 billion of senior unsecured notes that are due in March 2031 that bear interest at 2.95%. In May 2021, we completed an offer to exchange these notes for registered notes having substantially the same financial terms and covenants as the original notes (the unregistered and registered notes collectively, the “2.95% Notes”). The 2.95% Notes were issued at a price of 99.081% of the aggregate principal amount. Interest is payable semi-annually in arrears in March and September of each year, beginning September 15, 2021, and the interest rate is subject to adjustment based on certain ratings events. We may redeem some or all of the 2.95% Notes at any time prior to December 15, 2030 by paying a “make-whole” premium plus accrued and unpaid interest, if any. We may redeem some or all of the 2.95% Notes on or after December 15, 2030 at par plus accrued and unpaid interest, if any. The net proceeds from the issuance of the 2.95% Notes was approximately $982 million after deducting the discount and debt issuance costs. In addition to registering the 2.95% Notes in May 2021, we also completed an offer to exchange the $500 million of senior unsecured notes due December 2023 bearing interest at 3.6% and the $750 million of senior unsecured notes due August 2027 bearing interest at 4.625%, both privately placed in July 2020, for registered notes having substantially the same financial terms and covenants as the original notes. Additional information about our outstanding senior notes (collectively the “Senior Notes”), see Note 8 – Debt of the Notes to Consolidated Financial Statements in our 2020 Form 10-K. All of our outstanding Senior Notes are senior unsecured obligations issued by Expedia Group and guaranteed by certain domestic Expedia Group subsidiaries. The Senior Notes rank equally in right of payment with all of our existing and future unsecured and unsubordinated obligations of Expedia Group and the guarantor subsidiaries. In addition, the Senior Notes include covenants that limit our ability to (i) create certain liens, (ii) enter into sale/leaseback transactions and (iii) merge or consolidate with or into another entity or transfer substantially all of our assets. The Senior Notes are redeemable in whole or in part, at the option of the holders thereof, upon the occurrence of certain change of control triggering events at a purchase price in cash equal to 101% of the principal plus accrued and unpaid interest. Accrued interest related to the Senior Notes was $63 million and $110 million as of September 30, 2021 and December 31, 2020. Estimated Fair Value. The total estimated fair value of our Senior Notes was approximately $8.1 billion and $9.1 billion as of September 30, 2021 and December 31, 2020. Additionally, the estimated fair value of the Convertible Notes was $1.1 billion as of September 30, 2021. The fair value was determined based on quoted market prices in less active markets and is categorized according as Level 2 in the fair value hierarchy. Credit Facilities Revolving Credit Facility. As of September 30, 2021, Expedia Group maintained a $1.145 billion revolving credit facility with a group of lenders that expires on May 31, 2023 (the “Revolving Credit Facility”). Obligations under the Revolving Credit Facility are secured by substantially all of the assets of the Company and its subsidiaries that guarantee the facility (subject to certain exceptions, including for our headquarters located in Seattle, WA) up to the maximum amount permitted under the indentures governing the Senior Notes without securing such Senior Notes. Loans under the Revolving Credit Facility bear interest (A) in the case of eurocurrency loans, at rates ranging from (i) prior to December 31, 2021, 2.25% per annum and (ii) on and after December 31, 2021, or prior to such date for each quarter that the leverage ratio, as of the end of the most recently ended fiscal quarter for which financial statements have been delivered, calculated on an annualized basis using consolidated EBITDA for the two most recently ended fiscal quarters included in such financial statements multiplied by two, is not greater than 5.00:1.00, from 1.00% to 1.75% depending on the Company’s credit ratings, and (B) in the case of base rate loans, at rates (i) prior to December 31, 2021, 1.25% per annum and (ii) on and after December 31, 2021, or prior to such date if the leverage ratio condition referred to above is satisfied, from 0.00% to 0.75% per annum depending on the Company’s credit ratings. The Revolving Credit Facility contains covenants including a minimum liquidity requirement and, as of December 31, 2021, a maximum leverage ratio. As of September 30, 2021 and December 31, 2020, we had no Revolving Credit Facility borrowings outstanding. The amount of stand-by letters of credit (“LOC”) issued under the Revolving Credit Facility reduced the credit amount available. As of both September 30, 2021 and December 31, 2020, there was $13 million of outstanding stand-by LOCs issued under the facility. Foreign Credit Facility . As of September 30, 2021, the Company and Expedia Group International Holdings III, LLC (the “Borrower”) also maintained an $855 million credit facility with a group of lenders that expires on May 31, 2023 (the “Foreign Credit Facility”). Obligations under the Foreign Credit Facility are unsecured. Such obligations are guaranteed by the Company, its subsidiaries that guarantee obligations under the Revolving Credit Facility, as mentioned above, and certain of the Company’s additional subsidiaries. Loans under the Foreign Credit Facility bear interest at a rate equal to an index rate plus a margin (A) in the case of eurocurrency loans, (i) prior to December 31, 2021, equal to 2.50% per annum and (ii) on and after December 31, 2021, or prior to such date for each quarter that the leverage ratio, as of the end of the most recently ended fiscal quarter for which financial statements have been delivered, calculated on an annualized basis using consolidated EBITDA for the two most recently ended fiscal quarters included in such financial statements multiplied by two, is not greater than 5.00:1.00, ranging from 1.25% to 2.00% per annum, depending on the Company’s credit ratings, and (B) in the case of base rate loans, (i) prior to December 31, 2021, equal to 1.50% per annum and (ii) on and after December 31, 2021, or prior to such date if the leverage ratio condition referred to above is satisfied, ranging from 0.25% to per 1.00% annum, depending on the Company’s credit ratings. The covenants, events of default and other terms and conditions in the Foreign Credit Facility are substantially similar to those in the Revolving Credit Facility, but include additional limitations on the Borrower and certain other entities that are not obligors under the Revolving Credit Facility.

Equity [Abstract]
Capital Stock	Capital Stock Preferred Stock and Warrants On May 5, 2020, we issued and sold to (1) AP Fort Holdings, L.P., an affiliate of Apollo Global Management, Inc. (the “Apollo Purchaser”), 600,000 shares of the Company’s newly created Series A Preferred Stock, par value $0.001 per share (the “Series A Preferred Stock”) and Warrants (the “Warrants”) to purchase 4.2 million shares of our common stock for an aggregate purchase price of $588 million and (2) SLP V Fort Holdings II, L.P., affiliates of Silver Lake Group, L.L.C. (the “Silver Lake Purchasers”), 600,000 shares of Series A Preferred Stock and Warrants to purchase 4.2 million shares of common stock, for an aggregate purchase price of $588 million. Certificate of Designations for Series A Preferred Stock. Dividends on each share of Series A Preferred Stock accrued daily on the Preference Amount (as defined below) at the then-applicable Dividend Rate (as defined below) and were payable semi-annually in arrears. As used herein, “Dividend Rate” with respect to the Series A Preferred Stock meant from the closing until the day immediately preceding the fifth anniversary of the closing, 9.5% per annum. The Dividend Rate was also subject to certain adjustments if the Company incurred indebtedness causing its leverage to exceed certain thresholds. Dividends were payable until the third anniversary of the closing, either in cash or through an accrual of unpaid dividends (“Dividend Accrual”), at the Company’s option. At any time after the first anniversary of the closing but on or prior to the second anniversary of the closing, we could redeem all or any portion of the Series A Preferred Stock in cash at a price equal to 103% of the sum of the original liquidation preference of $1,000 per share of Series A Preferred Stock plus any Dividend Accruals (the “Preference Amount”), plus accrued and unpaid distributions as of the redemption date. The Series A Preferred Stock was classified within temporary equity on our consolidated balance sheets due to provisions that could cause the equity to be redeemable at the option of the holder. As of December 31, 2020, the carrying value of the Series A Preferred Stock was $1,022 million, net of $68 million in initial discount and issuance costs as well as $110 million allocated on a relative fair value basis to the concurrently issued Warrants recorded to additional paid-in capital (as described below). On May 20, 2021, we redeemed 50% of the outstanding Series A Preferred Stock at a price equal to 103% of the Preference Amount, plus accrued and unpaid distributions as to the redemption date using cash on-hand of $640 million, including an $18 million redemption premium and $22 million of accrued dividends. The loss on redemption of Preferred Stock was $107 million during the nine months ended September 30, 2021, which included a charge to additional paid-in capital for the redemption premium as well as $89 million related to 50% of the original issuance discount, issuance costs and the Warrants value. As of September 30, 2021, the carrying value of the remaining Series A Preferred Stock was $511 million. The Series A Preferred Stock accumulated $14 million and $64 million in total dividends during the three and nine months ended September 30, 2021, of which we paid $50 million (or $47.11 per share of Series A Preferred Stock) in dividends, including those mentioned above, during the nine months ended September 30, 2021. On October 15, 2021, we redeemed the remaining 50% of the outstanding Series A Preferred Stock at a price equal to 103% of the Preference Amount, plus accrued and unpaid distributions as to the redemption date using cash on-hand of $635 million, including an $18 million redemption premium and $17 million of accrued dividends. We anticipate the loss on redemption of Preferred Stock to be $107 million during the three months ended December 31, 2021, which will include a charge to additional paid-in capital for the redemption premium as well as $89 million related to 50% of the original issuance discount, issuance costs and the Warrants value. Warrants to Purchase Company Common Stock. Pursuant to the investment agreements, we issued to each of (1) the Silver Lake Purchasers (in the aggregate) and (2) the Apollo Purchaser, Warrants to purchase 4.2 million shares of our common stock at an exercise price of $72.00 per share, subject to certain customary anti-dilution adjustments provided under the Warrants, including for stock splits, reclassifications, combinations and dividends or distributions made by the Company on our common stock. The Warrants are exercisable on a net share settlement basis and expire ten years after the closing date. In May 2021, the Apollo Purchaser exercised all of the Warrants it held and received approximately 2.5 million shares of our common stock in respect thereof.

At this time, we do not currently expect to declare future dividends on our common stock. Future declarations of dividends are subject to final determination by our Board of Directors. Treasury Stock As of September 30, 2021, the Company’s treasury stock was comprised of approximately 124.2 million common stock and 7.3 million Class B shares. As of December 31, 2020, the Company’s treasury stock was comprised of approximately 123.5 million shares of common stock and 7.3 million Class B shares. Share Repurchases.

In December 2019, the Board of Directors authorized a repurchase of up to 20 million outstanding shares of our common stock. We made no share repurchases during the nine months ended September 30, 2021. During the nine months ended September 30, 2020, we repurchased, through open market transactions, 3.4 million shares under these authorizations for the total cost of $370 million, excluding transaction costs, representing an average repurchase price of $109.88 per share. As of September 30, 2021, there were approximately 23.3 million shares remaining under the 2018 and 2019 repurchase authorizations. There is no fixed termination date for the repurchases.

The earnings per share amounts are the same for common stock and Class B common stock because the holders of each class are legally entitled to equal per share distributions whether through dividends or in liquidation. Diluted earnings per share is calculated using our weighted-average outstanding common shares including the dilutive effect of stock awards and common stock warrants as determined under the treasury stock method and of our Convertible Notes using the if-converted method. In periods when we recognize a net loss, we exclude the impact of outstanding stock awards, common stock warrants and the potential share settlement impact related to our Convertible Notes from the diluted loss per share calculation as their inclusion would have an antidilutive effect. For the three months ended September 30, 2021, approximately 5 million of outstanding stock awards have been excluded from the calculations of diluted earnings per share attributable to common stockholders because their effect would have been antidilutive. For the nine months ended September 30, 2021, approximately 18 million of outstanding stock awards and common stock warrants and approximately 4 million shares related to the potential share settlement impact related to our Convertible Notes have been excluded from the calculations of diluted earnings per share attributable to common stockholders because their effect would have been antidilutive. For the three and nine months ended September 30, 2020, approximately 25 million of outstanding stock awards and common stock warrants were excluded.

Restructuring and Related Activities [Abstract]
Restructuring and Related Reorganization Charges	Restructuring and Related Reorganization Charges In 2020, we committed to restructuring actions intended to simplify our businesses and improve operational efficiencies, which have resulted in headcount reductions and office consolidations. As a result, we recognized $54 million and $206 million in restructuring and related reorganization charges during the nine months ended September 30, 2021 and 2020. Based on current plans, which are subject to change, we expect total reorganization charges in the remainder of 2021 of up to $10 million. However, we continue to actively evaluate additional cost reduction efforts and should we make decisions in future periods to take further actions we will incur additional reorganization charges. The following table summarizes the restructuring and related reorganization activity for the nine months ended September 30, 2021: Employee Severance and Benefits Other Total (In millions) Accrued liability as of January 1, 2021 $ 103 $ — $ 103 Charges 26 28 54 Payments (64) (6) (70) Non-cash items (4) (16) (20) Accrued liability as of September 30, 2021 $ 61 $ 6 $ 67

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We determine our provision for income taxes for interim periods using an estimate of our annual effective tax rate. We record any changes affecting the estimated annual effective tax rate in the interim period in which the change occurs, including discrete items. For the three months ended September 30, 2021, the effective tax rate was an 18.7% expense on pre-tax income, compared to a 10.8% benefit on pre-tax loss for the three months ended September 30, 2020. The change in the effective tax rate was primarily due to discrete items in the prior year. For the nine months ended September 30, 2021, the effective tax rate was a 25.3% benefit on a pre-tax loss, compared to a 12.0% benefit on pre-tax loss for the nine months ended September 30, 2020. The change in the effective tax rate was primarily due to nondeductible impairments and a valuation allowance recorded in the prior year. We are subject to taxation in the United States and foreign jurisdictions. Our income tax filings are regularly examined by federal, state and foreign tax authorities. During the fourth quarter of 2019, the Internal Revenue Service (“IRS”) issued final adjustments related to transfer pricing with our foreign subsidiaries for our 2011 to 2013 tax years. The proposed adjustments would increase our U.S. taxable income by $696 million, which would result in federal tax of approximately $244 million, subject to interest. We do not agree with the position of the IRS. We filed a protest with the IRS for our 2011 to 2013 tax years and Appeals returned the case to Exam for further review. We are also under examination by the IRS for our 2014 to 2016 tax years. Subsequent years remain open to examination by the IRS. We do not anticipate a significant impact to our gross unrecognized tax benefits within the next 12 months related to these years.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal Proceedings In the ordinary course of business, we are a party to various lawsuits. Management does not expect these lawsuits to have a material impact on the liquidity, results of operations, or financial condition of Expedia Group. We also evaluate other potential contingent matters, including value-added tax, excise tax, sales tax, transient occupancy or accommodation tax and similar matters. We do not believe that the aggregate amount of liability that could be reasonably possible with respect to these matters would have a material adverse effect on our financial results; however, litigation is inherently uncertain and the actual losses incurred in the event that our legal proceedings were to result in unfavorable outcomes could have a material adverse effect on our business and financial performance. Litigation Relating to Occupancy Taxes. One hundred three lawsuits have been filed by or against cities, counties and states involving hotel occupancy and other taxes. Ten lawsuits are currently active. These lawsuits are in various stages and we continue to defend against the claims made in them vigorously. With respect to the principal claims in these matters, we believe that the statutes or ordinances at issue do not apply to us or the services we provide and, therefore, that we do not owe the taxes that are claimed to be owed. We believe that the statutes or ordinances at issue generally impose occupancy and other taxes on entities that own, operate or control hotels (or similar businesses) or furnish or provide hotel rooms or similar accommodations. To date, forty-eight of these lawsuits have been dismissed. Some of these dismissals have been without prejudice and, generally, allow the governmental entity or entities to seek administrative remedies prior to pursuing further litigation. Thirty-four dismissals were based on a finding that we and the other defendants were not subject to the local tax ordinance or that the local government lacked standing to pursue its claims. As a result of this litigation and other attempts by certain jurisdictions to levy such taxes, we have established a reserve for the potential settlement of issues related to hotel occupancy and other taxes, consistent with applicable accounting principles and in light of all current facts and circumstances, in the amount of $50 million and $58 million as of September 30, 2021 and December 31, 2020, respectively. Our settlement reserve is based on our best estimate of probable losses and the ultimate resolution of these contingencies may be greater or less than the liabilities recorded. An estimate for a reasonably possible loss or range of loss in excess of the amount reserved cannot be made. Changes to the settlement reserve are included within legal reserves, occupancy tax and other in the consolidated statements of operations. Pay-to-Play. Certain jurisdictions may assert that we are required to pay any assessed taxes prior to being allowed to contest or litigate the applicability of the ordinances. This prepayment of contested taxes is referred to as “pay-to-play.” Payment of these amounts is not an admission that we believe we are subject to such taxes and, even when such payments are made, we continue to defend our position vigorously. If we prevail in the litigation, for which a pay-to-play payment was made, the jurisdiction collecting the payment will be required to repay such amounts and also may be required to pay interest. We are in various stages of inquiry or audit with various tax authorities, some of which, including in the City of Los Angeles regarding hotel occupancy taxes, may impose a pay-to-play requirement to challenge an adverse inquiry or audit result in court. Matters Relating to International VAT . We are in various stages of inquiry or audit in multiple European Union jurisdictions regarding the application of VAT to our European Union related transactions. While we believe we comply with applicable VAT laws, rules and regulations in the relevant jurisdictions, the tax authorities may determine that we owe additional taxes. In certain jurisdictions, including the United Kingdom, we may be required to “pay-to-play” any VAT assessment prior to contesting its validity. While we believe that we will be successful based on the merits of our positions with regard to audits in pay-to-play jurisdictions, it is nevertheless reasonably possible that we could be required to pay any assessed amounts in order to contest or litigate the applicability of any assessments and an estimate for a reasonably possible amount of any such payments cannot be made. Competition and Consumer Matters . On August 23, 2018, the Australian Competition and Consumer Commission, or "ACCC", instituted proceedings in the Australian Federal Court against trivago. The ACCC alleged breaches of Australian Consumer Law, or "ACL," relating to trivago’s advertisements in Australia concerning the hotel prices available on trivago’s Australian site, trivago’s strike-through pricing practice and other aspects of the way offers for accommodation were displayed on trivago's Australian website. The matter went to trial in September 2019 and, on January 20, 2020, the Australian Federal Court issued a judgment finding trivago had engaged in conduct in breach of the ACL. On March 4, 2020, trivago filed a notice of appeal of part of that judgment at the Australian Federal Court. On November 4, 2020, the Australian Federal Court dismissed trivago's appeal. On October 18 and 19, 2021, the Australian Federal Court heard submissions from the parties regarding penalties and other orders. In its submissions, the ACCC proposed a penalty of at least AU$90 million and an injunction restraining trivago from engaging in misleading conduct of the type found by the Australian Federal Court to be in contravention of the ACL. trivago submitted that an appropriate penalty for the court to impose would be in the order of up to AU$15 million. The parties await a ruling. We recorded an estimated probable loss of approximately $11 million with respect to these proceedings in a previous period. An estimate for the reasonable possible loss or range of loss in excess of the amount reserved cannot be made.

Discontinued Operations and Disposal Groups [Abstract]
Divestitures	Divestitures On May 4, 2021, we announced that American Express Global Business Travel (“GBT”) made a binding offer to acquire Egencia, Expedia Group’s corporate travel arm included within our B2B segment. On August 4, 2021, Expedia Group accepted that offer, and on November 1, 2021, the sale was completed. As part of the transaction, Expedia Group received a minority ownership position in the combined business, and entered into a 10-year lodging supply agreement with GBT. During the fourth quarter of 2021, we anticipate recognizing a significant gain on sale of the business. In addition, during the third quarter of 2020, in connection with our efforts to focus on our core businesses and streamline our activities, we committed to a plan to divest certain smaller businesses within our Retail segment, one of which, SilverRail, completed its sale in October 2020. In addition, in April 2021, we completed the sale of Classic Vacations, which resulted in an immaterial gain within other, net in the consolidated statement of operations and net cash divested of approximately $56 million. In July 2021, we also completed the sale of another of our smaller businesses, Alice, within our Retail segment, which resulted in a gain of $53 million within other, net in the consolidated statement of operations and net cash received of $84 million. As a result, the related assets and liabilities of the above disposal groups were considered held-for-sale and consisted of the following for each reporting period: • Held-for-sale assets of $408 million as of September 30, 2021, which were primarily classified within cash of $40 million, accounts receivable of $137 million, property and equipment of $61 million, operating lease right-of-use asset of $16 million and goodwill of $122 million. Held-for-sale assets of $21 million as of December 31, 2020, which were primarily classified within cash of $5 million, accounts receivable of $2 million and prepaid expenses and other current assets of $12 million. • Held-for-sale liabilities of $129 million as of September 30, 2021, which were primarily classified within merchant accounts payable of $27 million and accrued expenses and other current liabilities of $73 million. Held-for-sale liabilities of $53 million as of December 31, 2020, which were primarily classified within merchant accounts payable of $8 million, accrued expenses and other current liabilities of $5 million and deferred merchant bookings of $38 million.

Segment Information

Segment Reporting [Abstract]
Segment Information	Segment Information We have the following reportable segments: Retail, B2B, and trivago. Our Retail segment, which consists of the aggregation of operating segments, provides a full range of travel and advertising services to our worldwide customers through a variety of consumer brands including: Expedia.com and Hotels.com in the United States and localized Expedia and Hotels.com websites throughout the world, Vrbo, Orbitz, Travelocity, Wotif Group, ebookers, CheapTickets, Hotwire.com, CarRentals.com and Expedia Cruises. Our B2B segment is comprised of our Expedia Business Services organization including Expedia Partner Solutions, which offers private label and co-branded products to make travel services available to travelers through third-party company branded websites, and Egencia, a full-service travel management company that provides travel services to businesses and their corporate customers. Our trivago segment generates advertising revenue primarily from sending referrals to online travel companies and travel service providers from its hotel metasearch websites. We determined our operating segments based on how our chief operating decision makers manage our business, make operating decisions and evaluate operating performance. Our primary operating metric is Adjusted EBITDA. Adjusted EBITDA for our Retail and B2B segments includes allocations of certain expenses, primarily related to our global travel supply organization and the majority of costs from our product and technology platform, as well as facility costs and the realized foreign currency gains or losses related to the forward contracts hedging a component of our net merchant lodging revenue. We base the allocations primarily on transaction volumes and other usage metrics. We do not allocate certain shared expenses such as accounting, human resources, certain information technology and legal to our reportable segments. We include these expenses in Corporate and Eliminations. Our allocation methodology is periodically evaluated and may change. Our segment disclosure includes intersegment revenues, which primarily consist of advertising and media services provided by our trivago segment to our Retail segment. These intersegment transactions are recorded by each segment at amounts that approximate fair value as if the transactions were between third parties, and therefore, impact segment performance. However, the revenue and corresponding expense are eliminated in consolidation. The elimination of such intersegment transactions is included within Corporate and Eliminations in the table below. Corporate and Eliminations also includes unallocated corporate functions and expenses as well as Bodybuilding.com through its sale in May 2020. In addition, we record amortization of intangible assets and any related impairment, as well as stock-based compensation expense, restructuring and related reorganization charges, legal reserves, occupancy tax and other, and other items excluded from segment operating performance in Corporate and Eliminations. Such amounts are detailed in our segment reconciliation below. The following tables present our segment information for the three and nine months ended September 30, 2021 and 2020. As a significant portion of our property and equipment is not allocated to our operating segments and depreciation is not included in our segment measure, we do not report the assets by segment as it would not be meaningful. We do not regularly provide such information to our chief operating decision makers.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2021
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation These accompanying financial statements present our results of operations, financial position and cash flows on a consolidated basis. The unaudited consolidated financial statements include Expedia Group, Inc., our wholly-owned subsidiaries, and entities we control, or in which we have a variable interest and are the primary beneficiary of expected cash profits or losses. We have eliminated significant intercompany transactions and accounts.
Accounting Estimates	Accounting Estimates We use estimates and assumptions in the preparation of our interim unaudited consolidated financial statements in accordance with GAAP. Our estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of our interim unaudited consolidated financial statements. These estimates and assumptions also affect the reported amount of net income or loss during any period. Our actual financial results could differ significantly from these estimates. The significant estimates underlying our interim unaudited consolidated financial statements include revenue recognition; recoverability of current and long-lived assets, intangible assets and goodwill; income and transactional taxes, such as potential settlements related to occupancy and excise taxes; loss contingencies; deferred loyalty rewards; acquisition purchase price allocations; stock-based compensation; accounting for derivative instruments and provisions for credit losses, customer refunds and chargebacks. The COVID-19 pandemic has created and may continue to create significant uncertainty in macroeconomic conditions, which may cause further business disruptions and adversely impact our results of operations. As a result, many of our estimates and assumptions required increased judgment and carry a higher degree of variability and volatility. As events continue to evolve and additional information becomes available, our estimates may change materially in future periods.
Reclassifications	ReclassificationsWe have reclassified prior period financial statements to conform to the current period presentation. During the first quarter of 2021, we centralized the management of our licensing and maintenance costs and reclassified certain expenses to technology and content expense from within our other operating expense line items on our consolidated statements of operations.
Seasonality	Seasonality We generally experience seasonal fluctuations in the demand for our travel services. For example, traditional leisure travel bookings are generally the highest in the first three quarters as travelers plan and book their spring, summer and winter holiday travel. The number of bookings typically decreases in the fourth quarter. Because revenue for most of our travel services, including merchant and agency hotel, is recognized as the travel takes place rather than when it is booked, revenue typically lags bookings by several weeks for our hotel business and can be several months or more for our alternative accommodations business. Historically, Vrbo has seen seasonally stronger bookings in the first quarter of the year, with the relevant stays occurring during the peak summer travel months. The seasonal revenue impact is exacerbated with respect to income by the nature of our variable cost of revenue and direct sales and marketing costs, which we typically realize in closer alignment to booking volumes, and the more stable nature of our fixed costs. Furthermore, operating profits for our primary advertising business, trivago, have typically been experienced in the second half of the year, particularly the fourth quarter, as selling and marketing costs offset revenue in the first half of the year as we typically increase marketing during the busy booking period for spring, summer and winter holiday travel. As a result on a consolidated basis, revenue and income are typically the lowest in the first quarter and highest in the third quarter. The growth of our international operations, advertising business or a change in our product mix, including the growth of Vrbo, may influence the typical trend of the seasonality in the future.
Recently Adopted Accounting Policies	Recently Adopted Accounting Policies Simplifying the Accounting for Income Taxes. As of January 1, 2021, we adopted the Accounting Standards Updates (“ASU”) guidance to simplify the accounting for income taxes. This new standard eliminated certain exceptions in current guidance related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period, and the recognition of deferred tax liabilities for outside basis differences. It also clarified and simplified other aspects of the accounting for income taxes. The adoption of this new guidance did not have a material impact on our consolidated financial statement s . Investments - equity securities; Investments - Equity Method and Joint Ventures; Derivatives and Hedging. As of January 1, 2021, we adopted the new ASU guidance which clarified the interaction between the accounting for investments in equity securities, equity method investments and certain derivative instruments. The adoption of this new guidance did not have a material impact on our consolidated financial statement s . Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. As of January 1, 2021, we adopted the new ASU guidance which simplified the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. Specifically, the standard simplified accounting for convertible instruments by removing major separation models required under current GAAP, removing certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, which permitted more equity contracts to qualify for it, and simplified the diluted earnings per share calculation in certain areas. The adoption of this new guidance did not have a material impact on our consolidated financial statement s . The convertible senior notes issued in February 2021 are accounted for in accordance with this new guidance. See Note 4 – Debt for additional information.
Revenue	RevenuePrepaid Merchant Bookings. We classify payments made to suppliers in advance of Vrbo performance obligations as prepaid merchant bookings included within prepaid and other current assets. Deferred Merchant Bookings. We classify cash payments received in advance of our performance obligations as deferred merchant bookings. Practical Expedients and Exemptions. We have used the portfolio approach to account for our loyalty points as the rewards programs share similar characteristics within each program in relation to the value provided to the traveler and their breakage patterns. Using this portfolio approach is not expected to differ materially from applying the guidance to individual contracts. However, we will continue to assess and refine, if necessary, how a portfolio within each rewards program is defined. We do not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed.
Cash, Restricted Cash and Cash Equivalents	Cash, Restricted Cash and Cash EquivalentsOur cash and cash equivalents include cash and liquid financial instruments, including money market funds and term deposit investments, with maturities of three months or less when purchased. Restricted cash includes cash and cash equivalents that is restricted through legal contracts, regulations or our intention to use the cash for a specific purpose. Our restricted cash primarily relates to certain traveler deposits and to a lesser extent collateral for office leases.

Fair Value Measurements	We classify our cash equivalents and investments within Level 1 and Level 2 as we value our cash equivalents and investments using quoted market prices or alternative pricing sources and models utilizing market observable inputs. Valuation of the foreign currency forward contracts is based on foreign currency exchange rates in active markets, a Level 2 input.Derivative instruments are carried at fair value on our consolidated balance sheets. We use foreign currency forward contracts to economically hedge certain merchant revenue exposures, foreign denominated liabilities related to certain of our loyalty programs and our other foreign currency-denominated operating liabilities. Our goal in managing our foreign exchange risk is to reduce, to the extent practicable, our potential exposure to the changes that exchange rates might have on our earnings, cash flows and financial position. Our foreign currency forward contracts are typically short-term and, as they do not qualify for hedge accounting treatment, we classify the changes in their fair value in other, net.
