Use of Non-GAAP and Pro-Forma Financial MeasuresWe have provided the first-quarter 2010 and 2011 gross profit, gross margin, operating income, operating margin, net income, and earnings per ADS on a non-GAAP basis, which excludes share-based compensation expenses and amortization and deferred tax impact of acquired intangible assets. We believe both management and investors benefit from referring to these non-GAAP financial measures in assessing our financial performance and liquidity and when planning and forecasting future periods. These non-GAAP operating measures are useful for understanding and assessing underlying business performance and operating trends. We expect to continue to provide net income and earnings per ADS on a non-GAAP basis using a consistent method on a quarterly basis.
