Non-GAAP Financial Measures

To supplement our consolidated financial statements, which are prepared and presented in accordance with GAAP, we use the following non-GAAP financial measures: total revenue and advertising revenue excluding foreign exchange effect, non-GAAP costs and expenses, non-GAAP income from operations; non-GAAP net income; non-GAAP diluted shares; non-GAAP diluted earnings per share; non-GAAP operating margin; and non-GAAP effective tax rate. The presentation of these financial measures is not intended to be considered in isolation or as a substitute for, or superior to, financial information prepared and presented in accordance with GAAP. Investors are cautioned that there are material limitations associated with the use of non-GAAP financial measures as an analytical tool. In particular, many of the adjustments to our GAAP financial measures reflect the exclusion of items, specifically share-based compensation expense and payroll tax related to share-based compensation expense and the related income tax effects, that are recurring and will be reflected in our financial results for the foreseeable future. In addition, these measures may be different from non-GAAP financial measures used by other companies, limiting their usefulness for comparison purposes. We compensate for these limitations by providing specific information regarding the GAAP amounts excluded from these non-GAAP financial measures.

We believe these non-GAAP financial measures provide investors with useful supplemental information about the financial performance of our business, enable comparison of financial results between periods where certain items may vary independent of business performance, and allow for greater transparency with respect to key metrics used by management in operating our business.

We exclude the following items from one or more of our non-GAAP financial measures:

Share-based compensation expense. We exclude share-based compensation expense because we believe that the non-GAAP financial measures excluding this item provide meaningful supplemental information regarding operational performance. In particular, because of varying available valuation methodologies, subjective assumptions and the variety of award types that companies can use under FASB ASC Topic 718, we believe that providing non-GAAP financial measures that exclude this expense allow investors the ability to make more meaningful comparisons between our operating results and those of other companies. Furthermore, our share-based compensation expense was materially affected in the second quarter of 2012 due to the terms of our RSUs granted prior to 2011, related to which we recognized a cumulative $986 million in share-based compensation expense in the period, despite the fact that these awards were granted and earned over several years. Accordingly, we believe that excluding this expense provides investors and management with greater visibility to the underlying performance of our business operations, facilitates comparison of our results with other periods, and may also facilitate comparison with the results of other companies in our industry.

Payroll tax expense related to share-based compensation. We exclude payroll tax expense related to share-based compensation expense because, without excluding these tax expenses, investors would not see the full effect that excluding share-based compensation expense had on our operating results. Furthermore, our payroll tax expense was substantially higher due to

the terms of our RSUs granted prior to 2011, where, despite the fact that these awards were granted and earned over several years, we recognized $84 million in payroll tax expense in the nine months ended September 30, 2012, with most of this expense being recognized in the second quarter of 2012 and a partially offsetting credit recognized in third quarter of 2012. In addition, these expenses are tied to the exercise or vesting of underlying equity awards and the price of our common stock at the time of vesting or exercise, which factors may vary from period to period independent of the operating performance of our business. Similar to share-based compensation expense, we believe that excluding this payroll tax expense provides investors and management with greater visibility to the underlying performance of our business operations and facilitates comparison with other periods as well as the results of other companies.

Income tax effect of share-based compensation and related payroll tax expenses. We believe excluding the income tax effect of non-GAAP adjustments assists investors and management in understanding the tax provision related to those adjustments and provides useful supplemental information regarding the underlying performance of our business operations.

Assumed preferred stock conversion. As a result of our initial public offering, all outstanding shares of preferred stock were automatically converted into shares of Class B common stock. Consequently, non-GAAP diluted shares and net income per share for periods prior to June 30, 2012 have been calculated assuming this conversion, which we believe facilitates comparison with prior periods.

Dilutive securities and other dilutive equity awards excluded from GAAP. In our calculation of non-GAAP weighted average shares used to compute earnings per share attributable to Class A and Class B common stockholders for the three and nine months ended September 30, 2012, we give effect to antidilutive RSUs and stock options that are excluded from GAAP weighted average shares due to our reporting of a net loss. We also include unvested RSUs in the nine months ended September 30, 2012 as well as in the three and nine months ended September 30, 2011, the number of which is substantial due to the terms of RSUs granted prior to 2011. We believe including these awards facilitates comparison between periods.

Foreign exchange effect on total revenue and advertising revenue. We translate current quarter revenues using prior year exchange rates, which we believe is a useful metric that facilitates comparison to our historical performance.
