About our Non-GAAP Net Income and AdjustmentsUse of Non-GAAP Financial Information To supplement our condensed consolidated financial results prepared in accordance with GAAP, we use non-GAAP measures of net income and earnings per diluted share that are GAAP net income and GAAP earnings per diluted share adjusted to exclude certain recurring and non-recurring costs, expenses, and gains. We believe that the presentation of non-GAAP net income and non-GAAP earnings per diluted share provides important supplemental information regarding non-cash expenses, significant recurring and non-recurring items that we believe are important to understanding our financial and business trends relating to our financial condition and results of operations. Non-GAAP net income and non-GAAP earnings per diluted share are among the primary indicators used by management as a basis for planning and forecasting future periods and by management and our board of directors to determine whether our operating performance has met specified targets and thresholds. Management uses non-GAAP net income and non-GAAP earnings per diluted share when evaluating operating performance because it believes that the exclusion of the items described below, for which the amounts and/or timing may vary significantly depending upon the Company's activities and other factors, facilitates comparability of the Company's operating performance from period to period. We have chosen to provide this information to investors so they can analyze our operating results in the same way that management does and use this information in their assessment of our business and the valuation of our Company. Use and Economic Substance of Non-GAAP Financial Measures We compute non-GAAP net income and non-GAAP earnings per diluted share by adjusting GAAP net income and GAAP earnings per diluted share to remove the impact of recurring amortization of acquisition-related intangibles and stock-based compensation expense, as well as restructuring-related and non-recurring charges and gains and the tax effect of these adjustments. Such non-recurring charges and gains include acquisition-related transaction costs and the costs to integrate such acquisitions into our business, sale of a non-strategic minority investment in a privately held company, and changes in fair value of contingent consideration.
