Non-GAAP Financial Measures This release and the accompanying tables include a discussion of adjusted EBITDA, adjusted net income, adjusted diluted net income per share and free cash flow, all of which are non-GAAP financial measures that are provided as a complement to results provided in accordance with accounting principles generally accepted in the United States of America ("GAAP"). The term "adjusted EBITDA" refers to a financial measure that we define as net income less provision for taxes, depreciation expense, amortization expense, stock-based compensation expense, interest and other income (expense), net. The term "adjusted net income" refers to a financial measure that we define as net income adjusted for amortization expense and stock-based compensation expense, net of estimated taxes. The term "adjusted diluted net income per share" refers to a financial measure that we define as adjusted net income divided by weighted average diluted shares outstanding. The term "free cash flow" refers to a financial measure that we define as net cash provided by operating activities, less capital expenditures and internal software development costs. These non-GAAP measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for, or superior to, GAAP results. In addition, our definition of adjusted EBITDA, adjusted net income, adjusted diluted net income per share and free cash flow may not be comparable to the definitions as reported by other companies.
