We use adjusted EBITDA to measure the operating performance of our business and for planning and evaluating the performance of our business segment. We provide adjusted net income because we feel it provides meaningful insight for the investment community into the performance of our business. We believe that net income (loss) is the performance measure calculated and presented in accordance with generally accepted accounting principles in the U.S. (“GAAP”) that is most directly comparable to adjusted EBITDA and adjusted net income. Additional information with respect to our use of each of these financial measures follows: Adjusted EBITDA, adjusted net income (loss) and adjusted diluted income (loss) per share, as used herein, are not necessarily comparable to other similarly titled measures of other companies. Adjusted EBITDA is computed by eliminating the following from net income (loss): (a) net income attributable to noncontrolling interests, net of tax; (b) interest; (c) income taxes; (d) depreciation and amortization; (e) acquisition and integration expenses; (f) EBITDA from discontinued operations; (g) loss (gain) on disposition of businesses/assets; (h) loss on early extinguishment of debt; (i) expenses associated with merger; (j) certain legal settlements and related expenses (k) net plant incident costs (credits); (l) business separation costs; (m) amortization of pension and postretirement actuarial losses (gains); and (n) restructuring, impairment and plant closing costs (credits). The reconciliation of adjusted EBITDA to net income (loss) is set forth in this appendix. Adjusted net income (loss) and adjusted diluted income (loss) per share are computed by eliminating the after tax impact of the following items from net income (loss: (a) net income attributable to noncontrolling interest; (b) acquisition and integration expenses, purchase accounting adjustments; (c) impact of certain foreign tax credit elections; (d) loss (income) from discontinued operations; (e) discount amortization on settlement financing associated with the terminated merger; (f) loss (gain) on disposition of businesses/assets; (g) loss on early extinguishment of debt; (h) expenses associated with the merger; (i) certain legal settlements and related expenses; (j) net plant incident costs (credits); (k) business separation costs; (l) amortization of pension and postretirement actuarial losses (gains); and (m) restructuring, impairment and plant closing costs (credits). The income tax impacts, if any, of each adjusting item represent a ratable allocation of the total difference between the unadjusted tax expense and the total adjusted tax expense, computed without consideration of any adjusting items using a with and without approach. We do not adjust for changes in tax valuation allowances because we do not believe it provides more meaningful information than is provided under GAAP. The reconciliation of adjusted net income (loss) to net income (loss) is set forth in this appendix. Management internally uses a free cash flow measure: (a) to evaluate the Company's liquidity, (b) to evaluate strategic investments, (c) to plan stock buyback and dividend levels and (d) to evaluate the Company's ability to incur and service debt. Free cash flow is not a defined term under U.S. GAAP, and it should not be inferred that the entire free cash flow amount is available for discretionary expenditures. The Company defines free cash flow as cash flow provided by operating activities less cash flow used in investing activities, excluding acquisition/disposition activities and non-recurring separation costs. Free cash flow is typically derived directly from the Company's condensed consolidated statement of cash flows; however, it may be adjusted for items that affect comparability between periods.
