Use of Non-GAAP Financial MeasuresIn addition to the condensed consolidated financial statements presented in accordance with U.S. GAAP, management uses certain non-GAAP financial measures, including “Adjusted EBITDA” and “Adjusted EPS”. Adjusted EBITDA is not a recognized financial measure under U.S. GAAP, and does not purport to be an alternative to operating income or an indicator of operating performance. Adjusted EBITDA is presented to enhance an understanding of operating results and is not intended to represent cash flows or results of operations. The Board of Directors, lenders and management use Adjusted EBITDA primarily as an additional measure of operating performance for matters including executive compensation and competitor comparisons. The use of this non-GAAP measure provides an indication of the company’s ability to service debt, and management considers it an appropriate measure to use because of the company’s leveraged position. Adjusted EBITDA has certain material limitations, primarily due to the exclusion of certain amounts that are material to the company’s consolidated results of operations, such as interest expense, income tax expense, and depreciation and amortization. In addition, Adjusted EBITDA may differ from the Adjusted EBITDA calculations reported by other companies in the industry, limiting its usefulness as a comparative measure. The company uses Adjusted EBITDA to provide meaningful supplemental information regarding operating performance and profitability by excluding from EBITDA certain items that the company believes are not indicative of its ongoing operating results or will not impact future operating cash flows, which include restructuring and impairment charges, loss on early extinguishment of debt, stock compensation, costs associated with acquisitions and equity registrations, and other, net. Adjusted EPS is not a recognized financial measure under U.S. GAAP, does not purport to be an indicator of the company’s financial performance, and might not be consistent with measures used by other companies. The company’s management believes this supplemental measure is useful in understanding underlying trends of the business and analyzing the effects of certain events that are infrequent or unusual for the company.
