BASIS OF PRESENTATION	BASIS OF PRESENTATION Priceline.com Incorporated (the "Priceline Group" or 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 December 31, 2011. The Unaudited Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries, including without limitation, priceline.com International Ltd. ("PIL"), Booking.com B.V. ("Booking.com"), priceline.com Mauritius Company Limited ("Agoda.com"), and its majority-owned interest in TravelJigsaw Holdings Limited (known now as the rentalcars.com business) since its acquisition in May 2010. All inter-company accounts and transactions have been eliminated in consolidation. The functional currency of the Company’s foreign subsidiaries is generally the respective local currency. 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 the average exchange rates for the period. Translation gains and losses are included as a component of “Accumulated other comprehensive loss” on the accompanying Unaudited Consolidated Balance Sheets. Foreign currency transaction gains and losses are included on the Unaudited Consolidated Statements of Operations in “Foreign currency transactions and other.” Revenues, expenses, assets and liabilities can vary during each quarter of the year. Therefore, the results and trends in these interim financial statements may not be the same as those for the full year. Recent Accounting Pronouncements On January 1, 2012, the Company adopted the amended accounting guidance issued by the Financial Accounting Standards Board concerning the presentation of comprehensive income. The new guidance requires comprehensive income to be reported in either a single statement or in two consecutive statements reporting net income and other comprehensive income. The Company selected to present two consecutive statements. This amended guidance did not change the items that constitute net income or other comprehensive income, the timing of when other comprehensive income is reclassified to net income, or the earnings per share computation.
