Reconciliation of Non-GAAP Financial Measures

We define Adjusted EBITDA, which is a non-GAAP financial measure, as net income (loss) excluding income taxes, non-operating income or expenses, gain (loss) on extinguishment of debt and write-off of deferred financing costs, gain (loss) on interest rate swap contracts, gain (loss) on derivative contracts, gain (loss) on investments and sale of affiliate interests, interest expense, net, depreciation and amortization, share-based compensation, restructuring, impairments and other operating items (such as significant legal settlements and contractual payments for terminated employees). We define Adjusted EBITDA margin as Adjusted EBITDA divided by total revenue.

Adjusted EBITDA eliminates the significant non-cash depreciation and amortization expense that results from the capital-intensive nature of our business and from intangible assets recognized from acquisitions, as well as certain non-cash and other operating items that affect the period-to-period comparability of our operating performance. In addition, Adjusted EBITDA is unaffected by our capital and tax structures and by our investment activities.

We believe Adjusted EBITDA is an appropriate measure for evaluating our operating performance. Adjusted EBITDA and similar measures with similar titles are common performance measures used by investors, analysts and peers to compare performance in our industry. Internally, we use revenue and Adjusted EBITDA measures as important indicators of our business performance and evaluate management’s effectiveness with specific reference to these indicators. We believe Adjusted EBITDA provides management and investors a useful measure for period-to-period comparisons of our core business and operating results by excluding items that are not comparable across reporting periods or that do not otherwise relate to our ongoing operating results. Adjusted EBITDA should be viewed as a supplement to and not a substitute for operating income (loss), net income (loss), and other measures of performance presented in accordance with U.S. generally accepted accounting principles ("GAAP"). Since Adjusted EBITDA is not a measure of performance calculated in accordance with GAAP, this measure may not be comparable to similar measures with similar titles used by other companies.

We also use Free Cash Flow (defined as net cash flows from operating activities less cash capital expenditures) as a liquidity measure. We believe this measure is useful to investors in evaluating our ability to service our debt and make continuing investments with internally generated funds, although it may not be directly comparable to similar measures reported by other companies.

(12)Total passings represents the estimated number of single residence homes, apartments and condominium units passed by the HFC and FTTH network in areas serviceable without further extending the transmission lines. In addition, it includes commercial establishments that have connected to our HFC and FTTH network.

(13)Total Unique Customer Relationships represent the number of households/businesses that receive at least one of our fixed-line services.

Free accounts are included in the customer counts along with all active accounts, but they are limited to a prescribed group. Most of these accounts are also not entirely free, as they typically generate revenue through pay-per-view or other pay services and certain equipment fees. Free status is not granted to regular customers as a promotion. In counting bulk residential customers, such as an apartment building, we count each subscribing unit within the building as one customer, but do not count the master account for the entire building as a customer. We count a bulk commercial customer, such as a hotel, as one customer, and do not count individual room units at that hotel.
