This Annual Report on Form 10-K contains “non-GAAP financial measures”, that is, financial measures that either exclude or include amounts that are not excluded or included in the most directly comparable measure calculated and presented in accordance with the generally accepted accounting principles in the United States, referred to as “GAAP”. Specifically, we make use of the non-GAAP measures “Operating EBITDA” and “Operating EBITDA margin”.

Operating EBITDA is defined as operating income (loss) plus depreciation and amortization and non-recurring capital asset impairment charges. Operating EBITDA margin is Operating EBITDA expressed as a percentage of revenues. We use Operating EBITDA and Operating EBITDA margin as benchmark measurements of our own operating results and as benchmarks relative to our competitors. We consider them to be meaningful supplements to operating income (loss) as performance measures primarily because depreciation expense and non-recurring capital asset impairment charges are not actual cash costs and depreciation expense varies widely from company to company in a manner that we consider largely independent of the underlying cost efficiency of our operating facilities. In addition, we believe Operating EBITDA is commonly used by securities analysts, investors and other interested parties to evaluate our financial performance.

Operating EBITDA does not reflect the impact of a number of items that affect our net income (loss), including financing costs and the effect of derivative instruments. Operating EBITDA is not a measure of financial performance under GAAP, and should not be considered as an alternative to net income (loss) or operating income (loss) as a measure of performance, or as an alternative to net cash from (used in) operating activities as a measure of liquidity. Operating EBITDA and Operating EBITDA margin are internal measures and therefore may not be comparable to other companies.

Operating EBITDA has significant limitations as an analytical tool, and should not be considered in isolation, or as a substitute for analysis of our results as reported under GAAP. Some of these limitations are that Operating EBITDA does not reflect: (i) our cash expenditures, or future requirements, for capital expenditures or contractual commitments; (ii) changes in, or cash requirements for, working capital needs; (iii) the significant interest expense, or the cash requirements necessary to service interest or principal payments, on our outstanding debt; (iv) the impact of realized or marked to market changes in our derivative positions, which can be substantial; and (v) the impact of non-recurring impairment charges against our investments or assets. Because of these limitations, Operating EBITDA should only be considered as a supplemental performance measure and should not be considered as a measure of liquidity or cash available to us to invest in the growth of our business. Because all companies do not calculate Operating EBITDA in the same manner, Operating EBITDA as calculated by us may differ from Operating EBITDA or EBITDA as calculated by other companies. We compensate for these limitations by using Operating EBITDA as a supplemental measure of our performance and by relying primarily on our GAAP financial statements.
