We refer to net loss before interest and investment income, interest expense net of amounts capitalized, income tax expense, loss from redemption of debt, loss on investments, other expense (income), restructuring and related cost, depreciation and amortization, and share related payment expense as adjusted EBITDA. Adjusted EBITDA is not a measure of financial performance under U.S. GAAP. We believe adjusted EBITDA is a useful measure of our operating performance. We use adjusted EBITDA for budgetary and planning purposes; to assess the relative profitability and on-going performance of our consolidated operations; to compare our performance from period-to-period; and to compare our performance to that of our competitors. We also believe adjusted EBITDA is useful to investors to compare our operating performance to the performance of other communications, entertainment and media companies. We believe that investors use current and projected adjusted EBITDA to estimate our current or prospective enterprise value and to make investment decisions.

Because we fund and build-out our satellite radio system through the periodic raising and expenditure of large amounts of capital, our results of operations reflect significant charges for interest and depreciation expense. We believe adjusted EBITDA provides useful information about the operating performance of our business apart from the costs associated with our capital structure and physical plant. The exclusion of interest and depreciation and amortization expense is useful given fluctuations in interest rates and significant variation in depreciation and amortization expense that can result from the amount and timing of capital expenditures and potential variations in estimated useful lives, all of which can vary widely across different industries or among companies within the same industry. We believe the exclusion of taxes is appropriate for comparability purposes as the tax positions of companies can vary because of their differing abilities to take advantage of tax benefits and because of the tax policies of the various jurisdictions in which they operate. We believe the exclusion of restructuring and related costs is useful given the non-recurring nature of these transactions. We also believe the exclusion of share-based payment expense is useful given the significant variation in expense that can result from changes in the fair market value of our common stock. To compensate for the exclusion of taxes, other income (expense), depreciation and amortization and share-based payment expense, we separately measure and budget for these items.

There are material limitations associated with the use of adjusted EBITDA in evaluating our company compared with net loss, which reflects overall financial performance, including the effects of taxes, other income (expense), depreciation and amortization, restructuring and related costs, and share-based payment expense. We use adjusted EBITDA to supplement GAAP results to provide a more complete understanding of the factors and trends affecting the business than GAAP results alone. Investors that wish to compare and evaluate our operating results after giving effect for these costs, should refer to net loss as disclosed in our unaudited condensed consolidated statements of operations. Since adjusted EBITDA is a non-GAAP financial measure, our calculation of adjusted EBITDA may be susceptible to varying calculations; may not be comparable to other similarly titled measures of other companies; and should not be considered in isolation, as a substitute for, or superior to measures of financial performance prepared in accordance with GAAP. Please see our most recent filings on Form 10-Q and Form 10-K for additional information.
