33 Reconciliation of Non-GAAP Measures Adjusted EBITDA(1) and Free Cash Flow(2) (1)The Company defines Adjusted EBITDA as net income (loss) before cumulative effect of accounting change, interest, taxes, depreciation, amortization, debt extinguishment costs, non-cash asset and goodwill impairment write-offs, and non-cash losses on sale-leaseback of property and equipment. Lease expense and non-recurring charges are included in Adjusted EBITDA and include both cash and non-cash charges related to restructuring and integration expenses. In evaluating our business, management considers and uses Adjusted EBITDA as a key indicator of financial operating performance and as a measure of cash generating capability. Management believes this measure is useful as an analytical indicator of leverage capacity and debt servicing ability, and uses it to measure financial performance as well as for planning purposes. However, Adjusted EBITDA should not be considered as an alternative to net income, cash flow from operating activities or any other measures calculated in accordance with U.S. GAAP, or as an indicator of operating performance. The definition of Adjusted EBITDA used here may differ from that used by other companies. (2)The Company defines Free Cash Flow as Adjusted EBITDA from continuing operations, plus Special Items and net proceeds from sale of businesses, less cash paid for interest, taxes and Special Items, capital expenditures and changes in operating working capital. As detailed in Appendix I, for purposes of determining Free Cash Flow, Special Items, net, include those one-time costs, expenses and other charges incurred on a cash basis that are included in the determination of net income (loss) under GAAP and are not added back to net income (loss) in determining Adjusted EBITDA, but that management would consider important in evaluating the quality of the Company’s Free Cash Flow, as defined.
