Adjusted EBITDA is used as an analytical indicator of income generated to service debt and fund capital expenditures.In addition, multiples of current or projected Adjusted EBITDA are used to estimate current or prospective enterprise value. Adjusted 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.
