(1) Adjusted EBITDA, Core Adjusted EBITDA and Free Cash Flow are non-GAAP financial measures. These non-GAAP financial measures should be considered in addition to, but not as a substitute for, the information provided in accordance with GAAP. Reconciliations for these non-GAAP financial measures to the most directly comparable GAAP financial measures are provided in the Reconciliation of Non-GAAP Financial Measures to GAAP Financial Measures tables. We are not able to forecast Net income on a forward-looking basis without unreasonable efforts due to the high variability and difficulty in predicting certain items that affect Net income including, but not limited to, Income tax expense, stock-based compensation expense and Interest expense. Adjusted EBITDA and Core Adjusted EBITDA should not be used to predict Net income as the difference between either of the two measures and Net Income is variable.
