Priceline.com believes that Pro Forma gross profit and Pro Forma net income per share that exclude certain non-cash or non-recurring income or expense items are useful for analysts and investors to evaluate priceline.com's future on-going performance because they enable a more meaningful comparison of priceline.com's projected cash earnings and performance with its historical results from prior periods. These Pro Forma metrics are not intended to represent funds available for priceline.com's discretionary use and are not intended to represent or to be used as a substitute for operating income, net income or cash flows from operations data as measured under GAAP. The items excluded from these Pro Forma metrics, but included in the calculation of their closest GAAP equivalent, are significant components of consolidated statements of income and must be considered in performing a comprehensive assessment of overall financial performance. • For a complete list of the adjustments to these Pro Forma metrics and for a reconciliation of Pro Forma financial results with financial results under GAAP see priceline.com’s Form 8-K, dated September 16, 2008, filed with the Securities and Exchange Commission. • The presentation of Pro Forma financial information should not be considered in isolation or as a substitute for the financial information prepared and presented in accordance with generally accepted accounting principles in the United States.
