ADJUSTED SEGMENT EBITDA (D)

(D)The term Adjusted Segment EBITDA consists of operating income (loss) plus other income (expense), depreciation and amortization expense, impairments of assets and facility consolidation/closure and other charges, losses (gains) on extinguishment of Convertible Notes and executive transition costs, less gain on disposal of facility held for sale. Adjusted Segment EBITDA is not a measure of financial performance under GAAP and should not be considered in isolation from or as a substitute for operating income (loss) or cash flow measures prepared in accordance with GAAP or as a measure of profitability or liquidity. Additionally, Adjusted Segment EBITDA may not be comparable to other similarly titled measures of other companies. The Company has included Adjusted Segment EBITDA as supplemental disclosure because its management believes that Adjusted Segment EBITDA provides useful information regarding its ability to service debt and to fund capital expenditures and provides investors a helpful measure for comparing its operating performance with the performance of other companies that have different financing and capital structures or tax rates. The Company uses Adjusted Segment EBITDA to compare and to monitor the performance of its business segments to other comparable public companies and as a benchmark for the award of incentive compensation under its annual incentive compensation plan. The table above sets forth reconciliations of Adjusted Segment EBITDA to operating income (loss), which is the most directly comparable measure of financial performance calculated under GAAP.
