These non-GAAP measures are not in accordance with, or an alternative for, generally accepted accounting principles in the United States. The GAAP measures most comparable to Non-GAAP Operating (Loss) Income and Adjusted EBITDA are GAAP (loss) income from operations and GAAP net (loss) income, respectively. Reconciliations of these non-GAAP financial measures to the corresponding GAAP measures are included above. We define non-GAAP operating (loss) income as GAAP operating (loss) income excluding non-cash, stock-based compensation expense and amortization of acquired intangible assets. We define EBITDA as net (loss) income, excluding depreciation and amortization, interest expense, loss on extinguishment of debt, other income (expense), foreign exchange gain (loss) and provision for income taxes. We define Adjusted EBITDA as EBITDA, excluding non-cash share-based compensation expense. Note: |
