TABLE 4
Use of Non-GAAP Financial Measures and Notes

“OIBDA,” “Adjusted OIBDA,” “cash interest expense” and “free cash flow” are not financial measures calculated in accordance with generally accepted accounting principles (“GAAP”) in the United States. We define OIBDA as operating income before depreciation and amortization and Adjusted OIBDA as OIBDA plus investment income from affiliate. We define cash interest expense as interest expense, net, less non-cash amortization of deferred financing costs. For Mediacom Broadband LLC, we define free cash flow as OIBDA less capital expenditures, cash interest expense and dividends to preferred members. For Mediacom LLC, we define free cash flow as Adjusted OIBDA less capital expenditures and cash interest expense. OIBDA, Adjusted OIBDA, cash interest expense and free cash flow have inherent limitations as discussed below.

OIBDA and Adjusted OIBDA are some of the primary measures used by management to evaluate our performance and to forecast future results. We believe OIBDA and Adjusted OIBDA are useful for investors because it enables them to assess our performance in a manner similar to the methods used by management, and provides a measure that can be used to analyze value and compare the companies in the cable industry. A limitation of OIBDA and Adjusted OIBDA, however, is that they exclude depreciation and amortization, which represents the periodic costs of certain capitalized tangible and intangible assets used in generating revenues in our business. Management utilizes a separate process to budget, measure and evaluate capital expenditures. OIBDA and Adjusted OIBDA may not be comparable to similarly titled measures used by other companies, which may have different depreciation and amortization policies, and are key components in our covenant calculations, as defined under our debt arrangements.

Free cash flow is used by management to evaluate our ability to repay debt, and to facilitate the growth of our business with internally generated funds. A limitation of free cash flow, however, is that it may be affected by the timing of our capital spending. We believe free cash flow is useful for investors for the same reasons and provides measures that can be used to analyze value and compare companies in the cable television industry, although our measure of free cash flow may not be directly comparable to similar measures reported by other companies.

OIBDA, Adjusted OIBDA and free cash flow should not be regarded as alternatives to operating income or net income (loss) as indicators of operating performance, or to the statement of cash flows as measures of liquidity, nor should they be considered in isolation or as substitutes for financial measures prepared in accordance with GAAP. We believe that operating income is the most directly comparable GAAP financial measure to OIBDA and Adjusted OIBDA, and that net cash flows provided by operating activities is the most directly comparable GAAP financial measure to free cash flow.

Cash interest expense excludes the non-cash amortization of financing costs which were paid upon the financing of the relevant debt. We believe cash interest expense is useful for investors because it enables them to assess our cost of debt for the current period without including the non-cash amortization of financing costs that were previously paid. We believe interest expense, net, is the most directly comparable GAAP financial measure to cash interest expense.

For a reconciliation of OIBDA, Adjusted OIBDA, cash interest expense and free cash flow to their most directly comparable GAAP financial measures, see Table 3.
