EBITDA is defined as net income before interest expense, provision for income taxes, and depreciation and amortization expense. Free cash flow is defined as net cash flows provided by operating activities less capital expenditures. Free cash flow conversion is defined as free cash flow divided by EBITDA. The free cash flow conversion ratio is a non-GAAP measure and should not be considered a substitute for the ratio of cash flows from operating activities divided by net income determined in accordance with GAAP. The Company considers these non-GAAP measures in evaluating and managing the Company's operations and believes that discussion of results adjusted for these items is meaningful to investors because they provide a useful analysis of ongoing underlying trends. The adjusted measures are not in accordance with, nor are they a substitute for, GAAP measures, and they may not be comparable to similarly titled measures used by other companies. The net debt to EBITDA ratio on a trailing twelve month basis is a non- GAAP performance measure included because the Company believes it is useful to investors in evaluating the Company's leverage. The net debt to EBITDA ratio is defined as total debt, less cash and cash equivalents, divided by EBITDA. The net debt to EBITDA ratio is a non-GAAP measure and should not be considered a substitute for the ratio of total debt to net income determined in accordance with GAAP. The Company's calculation of its net debt to EBITDA ratio might not be calculated in the same manner as, and thus might not be comparable to, similarly titled measures used by other companies.
