23 EBITDA Reconciliation ($ millions) EBITDA is not intended to represent an alternative to operating income or cash flows from operating, financing or investing activities (as determined in accordance with generally accepted accounting principles (GAAP)) as a measure of performance, and is not representative of funds available for discretionary use due to the Company’s financing obligations. EBITDA, as defined by the Company, may not be calculated consistently among other companies applying similar reporting measures. EBITDA is included because it is a widely accepted financial indicator used by certain investors and financial analysts to assess and compare companies and is an integral part of the Company’s debt covenant calculations, and Adjusted EBITDA (EBITDA before management/board fees, financing and reorganization costs, and stock-based compensation costs) is included because the company’s financial guidance and certain compensation plans are based upon this measure. Management believes that EBITDA provides an important perspective on the Company’s ability to service its long-term obligations, the Company’s ability to fund continuing growth, and the Company’s ability to continue as a going concern. A reconciliation of net cash provided by operating activities to EBITDA and Adjusted EBITDA is included below. 2006 2007 Net cash provided by operating activities 20.1 $ 19.3 $ Changes in operating assets and liabilities (4.8) (2.4) Other non-cash expenses (1.0) (1.2) Income tax expense 0.2 0.2 Interest expense 7.8 8.1 EBITDA 22.3 24.0 Management and board fees 0.2 0.8 Stock-based compensation 0.4 0.4 Adjusted EBITDA 22.9 $ 25.2 $ 1st Quarter
