Use of Non-GAAP Financial Information

To supplement our condensed consolidated financial results prepared under generally accepted accounting principles, or 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 costs, expenses, and gains. A reconciliation of the adjustments to GAAP results for the three and six months ended June 30, 2017 and 2016 is provided below. In addition, an explanation of how management uses non-GAAP financial information to evaluate its business, the substance behind management’s decision to use this non-GAAP financial information, the material limitations associated with the use of non-GAAP financial information, the manner in which management compensates for those limitations, and the substantive reasons management believes that this non-GAAP financial information provides useful information to investors is included under “About our Non-GAAP Net Income and Adjustments” after the tables below.

These non-GAAP measures are not in accordance with or an alternative to GAAP and may be materially different from other non-GAAP measures, including similarly titled non-GAAP measures, used by other companies. The presentation of this additional information should not be considered in isolation from, as a substitute for, or superior to, net income or earnings per diluted share prepared in accordance with GAAP. Non-GAAP financial measures have limitations in that they do not reflect certain items that may have a material impact upon our reported financial results. We expect to continue to incur expenses of a nature similar to the non-GAAP adjustments described above, and exclusion of these items from our non-GAAP net income and non-GAAP earnings per diluted share should not be construed as an inference that these costs are unusual, infrequent, or non-recurring.

About our Non-GAAP Net Income and Adjustments

Use 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 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 certain costs, expenses, gains, and significant items that we believe are important to understanding 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 the exclusion of the items described below, for which the amounts and/or timing may vary significantly depending on our activities and other factors, facilitates comparability of our 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 amortization of acquisition-related intangibles, stock-based compensation expense, restructuring and other expenses, acquisition-related transaction expenses, costs to integrate such acquisitions into our business, incremental cost of revenue due to the fair value adjustment to inventories acquired in business combinations, changes in the fair value of contingent consideration, litigation settlement charges, and non-cash interest expense related to our 0.75% convertible senior notes (“Notes”). We use a constant non-GAAP tax rate of 19%, which we believe reflects the long term average tax rate based on our international structure and geographic distribution of revenue and profit.

Ex-Currency. To better understand trends in our business, we believe it is helpful to adjust our statement of operations to exclude the impact of year-over-year changes in the translation of foreign currencies into U.S. dollars. This is a non-GAAP measure that is calculated by adjusting revenue and non-GAAP net income by using historical exchange rates in effect during the comparable prior year period and removing the balance sheet currency remeasurement impact from interest income and other income (expense), net, including removal of any hedging gains and losses. We refer to these adjustments as “ex-currency.” Management believes the ex-currency measures provide investors with an additional perspective on year-over-year financial trends and enables investors to analyze our operating results in the same way management does. The year-over-year currency impact can be determined as the difference between year-over-year actual growth rates and year-over-year ex-currency growth rates.

These excluded items are described below:
