　　Non-GAAP Measures

　　This release contains the following non-GAAP financial measures: non-GAAP net revenues, non-GAAP non-advertising revenues, non-GAAP advertising and non-advertising gross margin, non-GAAP gross profit, non-GAAP operating expenses, non-GAAP income/(loss) from operations, non-GAAP income/(loss) from equity investments, non-GAAP net income/(loss) attributable to SINA and non-GAAP diluted net income/(loss) per share attributable to SINA. These non-GAAP financial measures should be considered in addition to, not as a substitute for, measures of the Company’s financial performance prepared in accordance with U.S. 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。”

　　The Company’s non-GAAP financial measures exclude stock-based compensation, amortization of intangible assets, net of tax and convertible debt issuance cost, recognition of deferred revenue in relation to the equity investment in E-House/ CRIC and gain/loss resulting from the disposal, purchase or impairment of a business, investment or non-controlling interest in a subsidiary and change in fair value of investor option liability. The Company’s management uses these non-GAAP financial measures in their financial and operating decision-making, because management believes these measures reflect the Company’s ongoing business operations in a manner that allows more meaningful period-to-period comparisons. The Company believes that these non-GAAP financial measures provide useful information to investors and others in the following ways: (i) in comparing the Company’s current financial results with the Company’s past financial results in a consistent manner, and (ii) 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 also believes that 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 the Company's core operating results and business outlook。

　　Use of non-GAAP financial measures has limitations. The Company’s non-GAAP financial measures do not include all income and expense items that affect the Company’s operations. They may not be comparable to non-GAAP financial measures used by other companies. Management compensates for these limitations by also considering the Company’s financial results prepared in accordance with U.S. GAAP。
