Non-GAAP Financial Measure

Adjusted EBITDA, the non-GAAP measure presented in this press release and supplementary information, is not a measure of performance under the accounting principles generally accepted in the United States ("GAAP"). This non-GAAP financial measure has limitations as an analytical tool, including that it does not have a standardized meaning. When assessing our operating performance, this non-GAAP financial measure should not be considered a substitute for, and investors should also consider, income before income taxes, income from operations, net income attributable to the Company, earnings per share and other measures of performance as defined by GAAP as indicators of the Company's performance or profitability.

EBITDA is a non-GAAP financial measure representing our earnings before interest expense, interest income, income tax expense, depreciation, and amortization. We define Adjusted EBITDA as net income (loss) before interest expense, interest income, income tax expense, depreciation and amortization expense, stock-based compensation expense, bargain purchase gain, net, and loss on write down of impaired assets and associated removal costs.

We use this non-GAAP financial measure as a means to evaluate period-to-period comparisons. Our management believes that this non-GAAP financial measure provides meaningful supplemental information regarding our performance by excluding certain expenses and charges that may not be indicative of the operating results of our recurring core business, such as stock-based compensation expense. We believe that both management and investors benefit from referring to this non-GAAP financial measure in assessing our performance.
