Yahoo! Inc. Note to Unaudited Condensed Consolidated Financial StatementsThis press release and its attachments include the non-GAAP financial measures of revenue excluding traffic acquisition costs (“revenue ex-TAC”), free cash flow, non-GAAP income from operations, non-GAAP net income, and non-GAAP net income per diluted share, which are reconciled to revenue, cash flow from operating activities, income from operations, net income attributable to Yahoo! Inc., and net income attributable to Yahoo! Inc. common stockholders per share - diluted, which we believe are the most comparable GAAP measures. We use these non-GAAP financial measures for internal managerial purposes and to facilitate period-to-period comparisons. We describe limitations specific to each non-GAAP financial measure below. Management generally compensates for limitations in the use of non-GAAP financial measures by relying on comparable GAAP financial measures and providing investors with a reconciliation of the non-GAAP financial measure to the most directly comparable GAAP financial measure or measures. Further, management uses non-GAAP financial measures only in addition to and in conjunction with results presented in accordance with GAAP. We believe that these non-GAAP financial measures reflect an additional way of viewing aspects of our operations that, when viewed with our GAAP results, provide a more complete understanding of factors and trends affecting our business and operating costs. These non-GAAP measures should be considered as a supplement to, and not as a substitute for, or superior to, revenue, cash flow from operating activities, income from operations, net income attributable to Yahoo! Inc., and net income attributable to Yahoo! Inc. common stockholders per share - diluted calculated in accordance with GAAP. Revenue ex-TAC is a non-GAAP financial measure defined as GAAP revenue less TAC. TAC consists of payments made to third-party entities that have integrated our advertising offerings into their Websites or other offerings (those Websites and other offerings, “Affiliate sites”) and payments made to companies that direct consumer and business traffic to Yahoo!’s online properties and services (“Yahoo! Properties”). Based on the terms of the Search Agreement with Microsoft, Microsoft retains a revenue share of 12 percent of the net (after TAC) search revenue generated on Yahoo! Properties and Affiliate sites in transitioned markets. Yahoo! reports the net revenue it receives under the Search Agreement as revenue and no longer presents the associated TAC. Accordingly, for transitioned markets Yahoo! reports GAAP revenue associated with the Search Agreement on a net (after TAC) basis rather than a gross basis. For markets that have not yet transitioned, revenue continues to be recorded on a gross basis, and TAC is recorded as a part of operating expenses. We present revenue ex-TAC to provide investors a metric used by the Company for evaluation and decision-making purposes during the Microsoft transition and to provide investors with comparable revenue numbers when comparing periods preceding, during and following the transition period. A limitation of revenue ex-TAC is that it is a measure which we have defined for internal and investor purposes that may be unique to the Company, and therefore it may not enhance the comparability of our results to other companies in our industry who have similar business arrangements but address the impact of TAC differently. Management compensates for these limitations by also relying on the comparable GAAP financial measures of revenue and total operating expenses, which includes TAC in non-transitioned markets.
