(**) Performance is measured based on category contribution margin or category Adjusted EBITDA, reflecting only the direct controllable revenue and operating expenses of the categories. As such, management’s measure of profitability for these categories does not include the effect of corporate overhead, described above, depreciation and amortization, other income (net), nor does it include one-time charges. Management utilizes EBITDA, and adjusted financial information, as a performance measurement tool because it considers such information a meaningful supplemental measure of its performance and believes it is frequently used by the investment community in the evaluation of companies with comparable market capitalization. The Company also uses EBITDA and adjusted financial information as one of the factors used to determine the total amount of bonuses available to be awarded to executive officers and other employees. The Company’s credit agreement uses EBITDA and adjusted financial information to measure compliance with covenants such as interest coverage and debt incurrence. EBITDA and adjusted financial information is also used by the Company to evaluate and price potential acquisition candidates. EBITDA and adjusted financial information have limitations as an analytical tool, and should not be considered in isolation or as a substitute for analysis of the Company's results as reported under GAAP. Some of these limitations are: (a) EBITDA does not reflect changes in, or cash requirements for, the Company's working capital needs; (b) EBITDA does not reflect the significant interest expense, or the cash requirements necessary to service interest or principal payments, on the Company's debts; and (c) although depreciation and amortization are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future, and EBITDA does not reflect any cash requirements for such capital expenditures. Because of these limitations, EBITDA should only be used on a supplemental basis combined with GAAP results when evaluating the Company's performance.
