Adjusted pre-tax income is defined as income before income taxes as further adjusted for certain items which are described in more detail below, which management believes are not representative of our operating performance. Adjusted pre-tax income excludes gains and losses on interest rate swaps. Adjusted net income is defined as net income further adjusted for the item discussed above, net of income tax.
EBITDA, Adjusted EBITDA, Adjusted pre-tax income, and Adjusted net income are not presentations made in accordance with U.S. GAAP, and should not be considered as alternatives to, or more meaningful than, amounts determined in accordance with U.S. GAAP, including net income, or net cash from operating activities.
We believe that EBITDA, Adjusted EBITDA, Adjusted pre-tax income and Adjusted net income are useful to an investor in evaluating our operating performance because:
-- these measures are widely used by securities analysts and investors to measure a company's operating performance without regard to items such as interest and debt expense, income tax expense, depreciation and amortization, gains and losses on interest rate swaps, and the write-off of deferred financing costs, which can vary substantially from company to company depending upon accounting methods and book value of assets, capital structure and the method by which assets were acquired;-- these measures help investors to more meaningfully evaluate and compare the results of our operations from period to period by removing the impact of our capital structure, our asset base and certain non-routine events which we do not expect to occur in the future; and -- these measures are used by our management for various purposes, including as measures of operating performance to assist in comparing performance from period to period on a consistent basis, in presentations to our board of directors concerning our financial performance and as a basis for strategic planning and forecasting.
