EBITDA represents net earnings (loss) before income tax expense (benefit), interest expense (income) and depreciation of property, plant and equipment. The Company believes EBITDA is useful to investors in evaluating ARI's operating performance compared to that of other companies in the same industry. In addition, ARI's management uses EBITDA to evaluate operating performance. The calculation of EBITDA eliminates the effects of financing, income taxes and the accounting effects of capital spending. These items may vary for different companies for reasons unrelated to the overall operating performance of a company's business. EBITDA is not a financial measure presented in accordance with U.S. generally accepted accounting principles (U.S. GAAP). Accordingly, when analyzing the Company's operating performance, investors should not consider EBITDA in isolation or as a substitute for net earnings (loss), cash flows from operating activities or other statements of operations or statements of cash flow data prepared in accordance with U.S. GAAP. The calculation of EBITDA is not necessarily comparable to that of other similarly titled measures reported by other companies. Adjusted EBITDA represents EBITDA before stock based compensation expense (income) related to stock options, restricted stock grants and stock appreciation rights (SARs), before gains or losses on investments, before a gain on asset conversion related to the involuntary replacement of assets, and before charges incurred in connection with the Company's retirement benefit plan separation agreement. Management believes that Adjusted EBITDA is useful to investors in evaluating the Company's operating performance, and therefore uses Adjusted EBITDA for that purpose. The Company's SARs, which settle in cash, are revalued each quarter based primarily upon changes in ARI's stock price. Management believes that eliminating the expense or income associated with the above items allows management and ARI's investors to understand better the operating results independent of those items. Adjusted EBITDA is not a financial measure presented in accordance with U.S. GAAP. Accordingly, when analyzing operating performance, investors should not consider Adjusted EBITDA in isolation or as a substitute for net earnings (loss), cash flows from operating activities or other statements of operations or statements of cash flow data prepared in accordance with U.S. GAAP. The Company's calculation of Adjusted EBITDA is not necessarily comparable to that of other similarly titled measures reported by other companies.
