TABLE 4

Use of Non-GAAP Financial Measures

“OIBDA,”, “Adjusted OIBDA”, “cash interest expense,” “free cash flow” and “net debt” 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 excluding deferred compensation. We define cash interest expense as interest expense, net, less amortization of deferred financing costs. We define free cash flow as Adjusted OIBDA less capital expenditures, cash interest expense and dividends to preferred members. We define net debt as total debt less cash and cash equivalents.

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 provide measures that can be used to analyze our value and evaluate our performance compared to other companies in the cable industry. A limitation of OIBDA and Adjusted OIBDA, however, is that it excludes 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. In addition, Adjusted OIBDA also has the limitation of not reflecting the effect of our deferred compensation. 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.

Free cash flow is used by management to evaluate our ability to repay debt and 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 as it provides an additional measure that can be used to analyze our value and evaluate our performance compared to other companies in the cable industry. Free cash flow may not be comparable to similarly titled measures reported by other companies.

OIBDA, Adjusted OIBDA and free cash flow should not be regarded as alternatives to operating income or net income 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 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 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.

Net debt is used as an alternative to total debt for comparison purposes under certain circumstances in which we have greater than usual levels of cash. On April 15, 2019, we completed the redemption of $150.0 million principal amount outstanding of our 5½% senior notes due 2021 (the “5½% Notes”) at an aggregate redemption price of $150.0 million, which was funded in part by $117.9 million of excess cash. On April 2, 2018, we completed the redemption of all of our outstanding 6³/₈% senior notes due 2023 at an aggregate redemption price of $309.6 million, which was funded in part by $158.0 million of excess cash. Due to timing of the transactions, we temporarily had greater than usual levels of cash as of both March 31, 2019 and 2018, and therefore we believe net debt to be a more appropriate comparative measure for periods where excess cash is held for the purpose of retiring debt.

For reconciliations of OIBDA, cash interest expense and free cash flow to their most directly comparable GAAP financial measures, see Table 2.
