Such statements constitute “forward-looking statements”, which are subject to the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995. Forward-looking statements involve substantial known and unknown risks, uncertainties and assumptions that could cause actual results, performance or achievements to differ materially from any future results, performance or achievements expressed or implied by the forward-looking statements.

Use of Non-GAAP Financial Measures

Adjusted EBITDA, non-GAAP net income and non-GAAP net income per diluted share attributable to common stockholders are financial measures that are not calculated in accordance with accounting principles generally accepted in the United States, or GAAP.

We define Adjusted EBITDA as net income adjusted to exclude acquisition, restructuring and certain legal costs, income taxes, interest income and expense, depreciation and amortization and stock-based compensation expense. Non-GAAP net income and non-GAAP net income per diluted share attributable to common stockholders exclude acquisition, restructuring and certain legal costs, amortization of acquired intangible assets, stock-based compensation expense and other nonrecurring items as well as the income tax effects of these non-GAAP adjustments. We use these non-GAAP financial measures as key performance measures because we believe they facilitate operating performance comparisons from period to period by excluding potential differences primarily caused by variations in capital structures, tax positions, the impact of acquisitions and restructuring, the impact of depreciation and amortization expense on our fixed assets and the impact of stock-based compensation expense. Adjusted EBITDA, non-GAAP net income and non-GAAP net income per diluted share attributable to common stockholders are not measurements of our financial performance under GAAP and should not be considered as an alternative to performance measures derived in accordance with GAAP.

See “Schedule of Non-GAAP Financial Measures Reconciliation” below for a reconciliation of net income to Adjusted EBITDA, non-GAAP net income and non-GAAP net income per diluted share attributable to common stockholders.
