EBITDA is not presented as an alternative measure of operating results or cash flows from operations as determined in accordance with accounting principles accepted in the United States of America. Management uses EBITDA to evaluate the operating performance of its business, and it is a measure of performance used by some investors, security analysts and others to make informed investment decisions. EBITDA is used as an analytical indicator of income generated to service debt and fund capital expenditures.In addition, multiples of current or projected EBITDA are used to estimate current or prospective enterprise value. EBITDA does not give effect to cash used for debt service requirements, and thus does not reflect funds available for investment or other discretionary uses.
