EBITDA is defined as net income (loss) before interest expense, provision (benefit) for income taxes, and depreciation and amortization expense. Free cash flow is defined as net cash flows provided by operating activities minus capital expenditures. 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.
