TABLE 4

Use of Non-GAAP Financial Measures

“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. We define cash interest expense as interest expense, net, less amortization of deferred financing costs. We define free cash flow as OIBDA less capital expenditures, cash interest expense and dividends to preferred members.

OIBDA is one of the primary measures used by management to evaluate our performance and to forecast future results. We believe OIBDA is 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, 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. OIBDA might 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 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 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.

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

TABLE 5

Changes in Accounting Standards – Revenue Recognition

As of January 1, 2018, we adopted Accounting Standards Update No. 2014-09 – Revenues from Contracts with Customers and related guidance (collectively, “revenue recognition”), which was issued by the Financial Accounting Standards Board. Adoption of this accounting standard affected both the timing of revenue recognition (the “timing change”) and the allocation of revenues among video, HSD and phone within our multi-product offerings, in which we offer product bundles at a discount (the “allocation change”). We adopted this accounting standard using a modified retrospective transition, and accordingly, the impact of such adoption was reflected in our financial results only for the three months ended September 30, 2018 and prior period results were not restated. The adoption of the new standard did not have a material impact on the results of operations of Mediacom Broadband LLC for the three months ended September 30, 2018. Excluding the impact of the timing change on Mediacom Broadband LLC, total revenues and OIBDA for the three months ended September 30, 2018, would have increased 4.5% and 4.8%, respectively. Because of the allocation change, we recorded a decrease in our video revenues and corresponding increases in our HSD and phone revenues. Excluding the overall impact of the timing change and the allocation change for Mediacom Broadband LLC, video revenues would have decreased 1.6%, HSD revenues would have increased 9.6% and phone revenues would have decreased 2.9% for the three months ended September 30, 2018.
