Consolidated and Combined Operating Results

(U.S. Dollars, in Millions)

Both prior to the Recapitalization and in connection with the Recapitalization, we have incurred significant non-recurring restructuring and other charges that impact our results of operations. As a result, our results of operations and cash flows are not indicative of what they would have been had we not incurred these non-recurring charges. We believe it would be helpful to provide a sensitivity analysis that describes our ability to satisfy our debt service, capital expenditures and working capital requirements in terms of earnings before interest, taxes, depreciation and amortization, or “EBITDA,” and EBITDA adjusted for the restructuring and other charges described below, or “Adjusted EBITDA.” Not only do we believe these non-GAAP measures can assist investors in understanding our cost structure, cash flows and financial position, but also financial covenants and ratios in our senior credit facilities and our indentures, such as restrictions on payments and indebtedness and ratios relating to leverage, interest coverage and fixed charge coverage, are also tied to measures that are calculated by adjusting EBITDA as described below. We believe it is necessary to adjust EBITDA to enable investors to see how we view our business given the significant non-recurring restructuring and other charges that have historically affected our results of operations.

Neither EBITDA nor Adjusted EBITDA are calculated under GAAP and neither should be considered in isolation or as a substitute for net income, cash flows or other income or cash flow data prepared in accordance with GAAP or as a measure of our profitability or liquidity. While EBITDA and Adjusted EBITDA and similar variations thereof are frequently used as a measure of operations and the ability to meet debt service requirements, these terms are not necessarily comparable to other similarly titled captions of other companies due to the potential inconsistencies in the method of calculation.

The following table sets forth the components of net income, EBITDA and Adjusted EBITDA.
