In the attached presentation, the Company uses pro forma earnings before interest and taxes, depreciation and amortization (EBITDA), a non-GAAP financial measure, as the performance measure to evaluate segment performance. As defined in Regulation G, "Conditions for Use of Non-GAAP Financial Measures," a non-GAAP financial measure is a numerical measure of a company's historical or future performance, financial position or cash flow that excludes (includes) amounts, or is subject to adjustments that have the effect of excluding (including) amounts, that are included (excluded) in the most directly comparable measure calculated and presented in accordance with generally accepted accounting principles (GAAP).

The Company defines EBITDA as net earnings (loss) available for common shareholders, adjusted for: (i) items that do not impact earnings (loss) from continuing operations, such as extraordinary items, discontinued operations and the impact of accounting changes; (ii) income taxes; (iii) interest; (iv) depreciation and amortization; (v) dividends on preferred stock and (vi) loss on extinguishment on preferred stock. EBITDA may not be comparable to measures used by other companies. Additionally, EBITDA should be considered in conjunction with net earnings and other performance measures such as operating income or operating cash flow. In using adjusted EBITDA, the Company takes into account mark to market unrealized hedging gain or loss.
