Use of Non-GAAP Financial Measures

The company has supplemented its GAAP net loss with a non-GAAP measure of adjusted earnings before interest, taxes, depreciation, amortization and stock-based compensation (“adjusted EBITDA”).  Management believes that this non-GAAP financial measure provides useful supplemental information to management and investors regarding the performance of the company and facilitates a more meaningful comparison of results for current periods with previous operating results.  Additionally, it will assist management in analyzing future trends, making strategic and business decisions and establishing internal budgets and forecasts. A reconciliation of non-GAAP adjusted EBITDA to GAAP net loss (the most directly comparable GAAP measure) is provided in the schedule below.

There are limitations in using this non-GAAP financial measure because it is not prepared in accordance with GAAP and may be different from non-GAAP financial measures used by other companies.  This non-GAAP financial measure should not be considered in isolation or as a substitute for GAAP financial measures. Investors and potential investors should consider non-GAAP financial measures only in conjunction with the company’s consolidated financial statements prepared in accordance with GAAP and the reconciliations of the non-GAAP financial measure provided in the schedule below.
