Reconciliation of non-GAAP Measures A-2 Adjusted EBITDA is a non-U.S. GAAP measure. We calculate adjusted EBITDA to eliminate the impact of certain items we do not consider to be indicative of the performance of our ongoing operations. In addition, in evaluating adjusted EBITDA, you should be aware that in the future, we may incur expenses similar to the adjustments in the presentation of adjusted EBITDA. Our presentation of adjusted EBITDA should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items. We present adjusted EBITDA because we consider it to be an important supplemental measure of our performance and because we believe it is frequently used by securities analysts, investors and other interested parties in the evaluation of companies in our industry, many of which present EBITDA and a form of adjusted EBITDA when reporting their results. Adjusted EBITDA has limitations as an analytical tool, and should not be considered in isolation, or as a substitute for analysis of our results as reported under U.S. GAAP. We compensate for these limitations by relying primarily on our U.S. GAAP results and using adjusted EBITDA only supplementally. The following tables show our adjusted EBITDA and the reconciliation from net income (loss) on a consolidated basis and from operating income (loss) for our operating units and the reconciliation of free cash flow on a consolidated basis from our statement of cash flows.
