EBITDA is not a measure of cash flow as determined by generally accepted accounting principles ("GAAP"). EBITDA should not be considered as an alternative to, or more meaningful than net income or cash flow as determined in accordance with GAAP or as an indicator of a company's operating performance or liquidity. Certain items excluded from EBITDA are significant components in understanding and assessing a company's financial performance, such as a company's cost of capital and tax structure, as well as historic costs of depreciable assets, none of which are components of EBITDA. The Company's computations of EBITDA may not be comparable to other similarly titled measures of other companies. The Company believes that EBITDA is a widely followed measure of operating performance and may also be used by investors to measure the Company's ability to meet future debt service requirements, if any.
