15 Q&A

16 Appendix

17 * Use of Non - GAAP Financial Measures In assessing the performance of our business, management utilizes a variety of financial and performance measures . The key measure is Adjusted EBITDA . Adjusted EBITDA is a non - GAAP financial measure . We define adjusted EBITDA as net income (loss) plus depreciation and amortization expense, interest expense, taxes as further adjusted to eliminate the impact of, when applicable, other non - cash expenses or expenses that are unusual or non - recurring . We believe that Adjusted EBITDA is meaningful to our investors to enhance their understanding of our financial performance for the current period and our ability to generate cash flows from operations that are available for taxes, capital expenditures and debt service . We understand that Adjusted EBITDA is frequently used by securities analysts, investors and other interested parties as a measure of financial performance and to compare our performance with the performance of other companies that report Adjusted EBITDA . Our calculation of Adjusted EBITDA, however, may not be comparable to similarly titled measures reported by other companies . When assessing our operating performance, investors and others should not consider this data in isolation or as a substitute for net income (loss) calculated in accordance with GAAP . Further, the results presented by Adjusted EBITDA cannot be achieved without incurring the costs that the measure excludes . A reconciliation of Adjusted EBITDA to net income (loss), the most comparable GAAP measure, is provided below .
