(the "Company") is responsible for the Unaudited Consolidated Financial Statements included in this document. The Unaudited Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and include all normal and recurring adjustments that management of the Company considers necessary for a fair presentation of its financial position and operating results. The Company prepared the Unaudited Consolidated Financial Statements following the requirements of the Securities and Exchange Commission for interim reporting. As permitted under those rules, the Company condensed or omitted certain footnotes or other financial information that are normally required by GAAP for annual financial statements. These statements should be read in combination with the Consolidated Financial Statements in the Company's Annual Report on Form 10-K for the year ended </span><span style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">December 31, 2018</span><span style="font-family:inherit;font-size:10pt;">.</span></div><div style="line-height:120%;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:120%;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Unaudited Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries, including its primary brands of Booking.com, KAYAK, priceline, agoda, Rentalcars.com and OpenTable. In the third quarter of 2019, the Company reorganized its operating segments from six to four operating segments by combining Booking.com with Rentalcars.com and KAYAK with OpenTable, reflecting changes to the management structure. Considering the similarity in economic characteristics, other qualitative factors and the objectives and principles of ASC 280, </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Segment Reporting</span><span style="font-family:inherit;font-size:10pt;">, the operating segments continue to be aggregated into one reportable segment. All inter-company accounts and transactions have been eliminated in consolidation. The functional currency of the Company's subsidiaries is generally the respective local currency. For international operations, assets and liabilities are translated into U.S. Dollars at the rate of exchange existing at the balance sheet date. Income statement amounts are translated at monthly average exchange rates applicable for the period. Translation gains and losses are included as a component of "</span><span style="font-family:inherit;font-size:10pt;">Accumulated other comprehensive loss</span><span style="font-family:inherit;font-size:10pt;">" in the accompanying Consolidated Balance Sheets.

This new accounting update amended the guidance on the recognition and measurement of financial instruments. The effect of adopting this new accounting update resulted in an increase of </span><span style="font-family:inherit;font-size:10pt;"><span>$241 million</span></span><span style="font-family:inherit;font-size:10pt;"> to the Company’s retained earnings for the net unrealized gain, net of tax, related to marketable equity securities, with an offsetting adjustment to accumulated other comprehensive income as of January 1, 2018. However, in the Unaudited Consolidated Statements of Comprehensive Income for the three months ended March 31, 2018, six months ended June 30, 2018 and nine months ended September 30, 2018, the Company incorrectly presented the </span><span style="font-family:inherit;font-size:10pt;"><span>$241 million</span></span><span style="font-family:inherit;font-size:10pt;"> as a component of other comprehensive income (referred to as "Reclassification of net unrealized gains on marketable equity securities to retained earnings, net of tax charge"). Accordingly, the Company corrected the foregoing presentation error in the accompanying Unaudited Consolidated Statement of Comprehensive Income for the nine months ended September 30, 2018 in this Form 10-Q. As a result of this correction, total comprehensive income in the Company’s previously reported Unaudited Consolidated Statement of Comprehensive Income increased from </span><span style="font-family:inherit;font-size:10pt;"><span>$2.9 billion</span></span><span style="font-family:inherit;font-size:10pt;"> to </span><span style="font-family:inherit;font-size:10pt;"><span>$3.1 billion</span></span><span style="font-family:inherit;font-size:10pt;"> for the nine months ended September 30, 2018. The correction of this error had no effect on the Company’s previously reported Consolidated Balance Sheets, Unaudited Consolidated Statements of Operations, Unaudited Consolidated Statements of Changes in Stockholders’ Equity and Unaudited Consolidated Statements of Cash Flows. The effect of adopting this new accounting update has been presented correctly in the audited Consolidated Statement of Comprehensive Income included in the Consolidated Financial Statements in the Form 10-K for the year ended December 31, 2018. The Company presented the correction in the Unaudited Consolidated Statement of Comprehensive Income for the three months ended March 31, 2018 included in the Form 10-Q for the first quarter of 2019 and for the six months ended June 30, 2018 included in the Form 10-Q for the second quarter of 2019.</span></div><div style="line-height:120%;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Reclassifications</span><span style="font-family:inherit;font-size:10pt;"> — Certain amounts from prior periods have been reclassified to conform to the current year presentation.</span></div><div style="line-height:120%;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Restricted Cash and Cash Equivalents:</span><span style="font-family:inherit;font-size:10pt;"> Restricted cash and cash equivalents at </span><span style="font-family:inherit;font-size:10pt;">September 30, 2019</span><span style="font-family:inherit;font-size:10pt;"> and </span><span style="font-family:inherit;font-size:10pt;">December 31, 2018</span><span style="font-family:inherit;font-size:10pt;"> principally relates to the minimum cash requirement for Rentalcars.com's insurance business.

accounting update to address a customer's accounting for implementation costs incurred in a cloud computing arrangement that is a service contract and also added certain disclosure requirements related to implementation costs incurred for internal-use software and cloud computing arrangements. The amendment aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The Company utilizes various third-party computer systems and third-party service providers, including global distribution systems serving the accommodation, rental car and airline industries. The Company uses both internally-developed systems and third-party systems to operate its services, including transaction processing, order management and financial systems. The Company adopted this update on January 1, 2019 and applied it on a prospective basis.

The new standard retains the dual-model concept by requiring entities to determine if a lease is an operating or financing lease. The new standard also expands qualitative and quantitative disclosures for lessees. </span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company adopted this new standard on January 1, 2019 on a modified retrospective basis and has elected not to restate comparative periods. The Company elected other options, which allow the Company to use its previous evaluations regarding if an arrangement contains a lease, if a lease is an operating or financing lease and what costs are capitalized as initial direct costs prior to adoption. The Company also elected to combine lease and non-lease components.</span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Upon the adoption of the new lease standard, on January 1, 2019, the Company recognized operating lease assets of </span><span style="font-family:inherit;font-size:10pt;"><span>$646 million</span></span><span style="font-family:inherit;font-size:10pt;"> and total operating lease liabilities of </span><span style="font-family:inherit;font-size:10pt;"><span>$646 million</span></span><span style="font-family:inherit;font-size:10pt;"> (including a current liability of </span><span style="font-family:inherit;font-size:10pt;"><span>$152 million</span></span><span style="font-family:inherit;font-size:10pt;">) in the consolidated balance sheet and reclassified certain balances related to existing leases.

Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit's goodwill, which requires a hypothetical purchase price allocation, with the carrying amount of that reporting unit's goodwill. Under this update, an entity would perform its quantitative annual or interim goodwill impairment test using the current Step 1 test and recognize an impairment charge for the excess of the carrying value of a reporting unit over its fair value.</span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company plans to adopt this update in the first quarter of 2020.

For financial assets measured at amortized cost, this update requires an entity to (1) estimate its lifetime expected credit losses upon recognition of the financial assets and establish an allowance to present the net amount expected to be collected, (2) recognize this allowance and changes in the allowance during subsequent periods through net income and (3) consider relevant information about past events, current conditions and reasonable and supportable forecasts in assessing the lifetime expected credit losses. For available-for-sale debt securities, this update made several targeted amendments to the existing other-than-temporary impairment model, including (1) requiring disclosure of the allowance for credit losses, (2) allowing reversals of the previously recognized credit losses until the entity has the intent to sell, is more-likely-than-not required to sell the securities or the maturity of the securities, (3) limiting impairment to the difference between the amortized cost basis and fair value and (4) not allowing entities to consider the length of time that fair value has been less than amortized cost as a factor in evaluating whether a credit loss exists. </span></div><div style="line-height:120%;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div>The Company plans to adopt this update in the first quarter of 2020. Entities are required to apply this update on a modified retrospective basis with a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. In preparation for the adoption, the Company is currently evaluating the impact to its Consolidated Financial Statements and establishing the related processes and internal controls. The Company does not expect the adoption to have a material impact to its Consolidated Financial Statements.

Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit's goodwill, which requires a hypothetical purchase price allocation, with the carrying amount of that reporting unit's goodwill. Under this update, an entity would perform its quantitative annual or interim goodwill impairment test using the current Step 1 test and recognize an impairment charge for the excess of the carrying value of a reporting unit over its fair value.</span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company plans to adopt this update in the first quarter of 2020.

For financial assets measured at amortized cost, this update requires an entity to (1) estimate its lifetime expected credit losses upon recognition of the financial assets and establish an allowance to present the net amount expected to be collected, (2) recognize this allowance and changes in the allowance during subsequent periods through net income and (3) consider relevant information about past events, current conditions and reasonable and supportable forecasts in assessing the lifetime expected credit losses. For available-for-sale debt securities, this update made several targeted amendments to the existing other-than-temporary impairment model, including (1) requiring disclosure of the allowance for credit losses, (2) allowing reversals of the previously recognized credit losses until the entity has the intent to sell, is more-likely-than-not required to sell the securities or the maturity of the securities, (3) limiting impairment to the difference between the amortized cost basis and fair value and (4) not allowing entities to consider the length of time that fair value has been less than amortized cost as a factor in evaluating whether a credit loss exists. </span></div><div style="line-height:120%;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div>The Company plans to adopt this update in the first quarter of 2020. Entities are required to apply this update on a modified retrospective basis with a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. In preparation for the adoption, the Company is currently evaluating the impact to its Consolidated Financial Statements and establishing the related processes and internal controls. The Company does not expect the adoption to have a material impact to its Consolidated Financial Statements.
