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 six months ended June 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>$1.3 billion</span></span><span style="font-family:inherit;font-size:10pt;"> to </span><span style="font-family:inherit;font-size:10pt;"><span>$1.5 billion</span></span><span style="font-family:inherit;font-size:10pt;"> for the six months ended June 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 will present the correction in the Unaudited Consolidated Statement of Comprehensive Income for the nine months ended September 30, 2018 to be included in the Form 10-Q for the third 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;">June 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 established in 2017.

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;">For public business entities, this update is effective for their annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019.

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><div style="line-height:120%;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">This update is effective for public business entities for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years.

The Company is currently evaluating the impact to its Consolidated Financial Statements of adopting this update and does not expect it to have a material impact.</span></div>

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;">For public business entities, this update is effective for their annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests occurring after January 1, 2017. The update will be applied prospectively. The Company plans to adopt this update in the first quarter of 2020. </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;">Measurement of Credit Losses on Financial Instruments</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;">In June 2016, the FASB issued a new accounting update on the measurement of credit losses for financial assets measured at amortized cost, which includes accounts receivable, and available-for-sale debt securities. 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><div style="line-height:120%;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">This update is effective for public business entities for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. 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. The Company is currently evaluating the impact to its Consolidated Financial Statements of adopting this update and does not expect it to have a material impact.</span></div>
