　　Non-GAAP Measures

　　This release contains financial measures that are not prepared in accordance with generally accepted accounting principles in the United States (“GAAP”). These non-GAAP financial measures, which are used as measures of SINA’s performance, should be considered in addition to, not as a substitute for, measures of the Company’s financial performance prepared in accordance with GAAP. The Company’s non-GAAP financial measures may be defined differently than similar terms used by other companies. Accordingly, care should be exercised in understanding how the Company defines its non-GAAP financial measures.

　　Reconciliations of the Company’s non-GAAP measures to the nearest GAAP measures are set forth in the section below titled “Unaudited Reconciliation of Non-GAAP to GAAP Results.” These non-GAAP measures include non-GAAP non-advertising revenues, non-GAAP net revenues, non-GAAP gross profit, non-GAAP advertising gross margin, non-GAAP operating expenses, non-GAAP income from operations, non-GAAP equity income from CRIC, non-GAAP net income attributable to SINA and non-GAAP diluted net income per share attributable to SINA.

　　The Company’s management uses non-GAAP financial measures to gain an understanding of the Company’s comparative operating performance (when comparing such results with previous periods or forecasts) and future prospects. The Company’s non-GAAP financial measures exclude certain items, including stock-based compensation, amortization of intangible assets, recognition of deferred revenues and gain/loss resulting from the disposal, purchase or impairment of a business, investment or non-controlling interest in a subsidiary, from its internal financial statements for purposes of its internal budgets. Non-GAAP financial measures are used by the Company’s management in their financial and operating decision-making, because management believes they reflect the Company’s ongoing business in a manner that allows more meaningful period-to-period comparisons. The Company’s management believes that these non-GAAP financial measures provide useful information to investors and others in the following ways: 1) in comparing the Company’s current financial results with the Company’s past financial results in a consistent manner, and 2) in understanding and evaluating the Company’s current operating performance and future prospects in the same manner as management does, if they so choose. The Company’s management further believes the non-GAAP financial measures provide useful information to both management and investors by excluding certain expenses, gains/losses and other items (i) that are not expected to result in future cash payments or (ii) that are non-recurring in nature or may not be indicative of its core operating results and business outlook.

　　The Company’s management believes excluding stock-based compensation from its non-GAAP financial measures is useful for itself and investors, as such expense will not result in future cash payments and is not an indicator used by management to measure the Company’s core operating results and business outlook.

　　The Company’s management believes excluding the amortization expense of intangible assets from its non-GAAP financial measures is useful for itself and investors, because it enables a more meaningful comparison of the Company’s cash performance between reporting periods. In addition, such charges will not result in cash settlement in the future and is not an indicator used by management to measure the Company’s core operating results and business outlook.

　　The Company’s management believes excluding the recognition of deferred revenues, mostly relating to the license agreements resulting from SINA injecting its online real estate advertising business into its majority-owned subsidiary China Online Housing Technology Corporation (“COHT”) and exchanging its interest in COHT for approximately a 33% interest in CRIC upon the successful listing of CRIC on the NASDAQ Global Select Market in October 2009, from its non-GAAP financial measures is useful for itself and investors, because it enables a more meaningful comparison of the Company’s revenue performance between reporting periods. In addition, such revenues will not result in cash settlement in the future and is not an indicator used by management to measure the Company’s core operating results and business outlook.

　　The Company’s non-GAAP equity income from its interest in net income attributable to CRIC excludes stock-based compensation, amortization expense of intangible assets and gains from the purchase of a business, which are consistent with the Company’s adjusted items to calculate non-GAAP measures.

　　The Company’s management believes excluding gain/loss resulting from the disposal, purchase or impairment of a business, investment or non-controlling interest in a subsidiary from its non-GAAP financial measures is useful for itself and investors, because such gains/losses are not indicative of the Company’s core operating results.

　　The non-GAAP financial measures have limitations. They do not include all items of income and expense that affect the Company’s operations. Specifically, these non-GAAP financial measures are not prepared in accordance with GAAP, may not be comparable to non-GAAP financial measures used by other companies and, with respect to the non-GAAP financial measures that exclude certain items under GAAP, do not reflect any benefit that such items may confer to the Company. Management compensates for these limitations by also considering the Company’s financial results as determined in accordance with GAAP.
