ASC 606 Transition Exhibit 99.2

To supplement our financial information presented in accordance with generally accepted accounting principles in the United States (“GAAP”), we consider and have included certain non-GAAP financial measures in this presentation, including Adjusted EBITDA and non-GAAP net income. Management uses Adjusted EBITDA and non-GAAP net income as supplemental measures to review and assess the performance of our core business operations and for planning purposes. We define (i) Adjusted EBITDA as net income plus interest expense, taxes, depreciation and amortization, non-cash stock-based compensation expense, loss on early repayment of debt, certain transaction expenses that are not core to our operations and the change in fair value of our interest rate swap and (ii) non-GAAP net income as net income plus non-cash stock-based compensation expense, certain transaction expenses that are not core to our operations, loss on early repayment of debt and the change in the value of our interest rate swap, all of which are adjusted for the effect of income taxes. Adjusted EBITDA and non-GAAP net income are metrics that provide investors with greater transparency to the information used by management in its financial and operational decision-making. We believe these metrics are useful to investors because they facilitate comparisons of our core business operations across periods on a consistent basis, as well as comparisons with the results of peer companies, many of which use similar non-GAAP financial measures to supplement results under GAAP. In addition, Adjusted EBITDA is a measure that provides useful information to management about the amount of cash available for reinvestment in our business, repurchasing common stock and other purposes. Management believes that the non-GAAP measures presented in this presentation, when viewed in combination with our results prepared in accordance with GAAP, provide a more complete understanding of the factors and trends affecting our business and performance. Adjusted EBITDA and non-GAAP net income are not measures of financial performance under GAAP and should not be considered a substitute for net income, which we consider to be the most directly comparable GAAP measure. Adjusted EBITDA and non-GAAP net income have limitations as analytical tools, and when assessing our operating performance, you should not consider Adjusted EBITDA or non-GAAP net income in isolation, or as a substitute for net income or other consolidated statements of income data prepared in accordance with GAAP. Adjusted EBITDA and non-GAAP net income may not be comparable to similar titled measures of other companies and other companies may not calculate such measures in the same manner as we do.
