NON-GAAP RECONCILIATION In addition to Operating Income (Loss) determined in accordance with United States Generally Accepted Accounting Principles (GAAP), the Company uses non−GAAP financial measures, such as “EBITDA from continuing operations,” in assessing its operating performance. The Company believes that this non−GAAP measure serves as an appropriate measure to be used in evaluating the performance of its business. The Company defines free cash flow as cash flow from operations less capital expenditures. The Company defines EBITDA as Earnings before interest, taxes and depreciation and amortization. EBITDA from continuing operations is before other income (expense) and discontinued operations. EBITDA and EBITDA from continuing operations as defined by the Company may not be comparable to similarly titled measures reported by other companies. The Company does not intend for non−GAAP financial measures to be considered in isolation or as a substitute for other measures prepared in accordance with GAAP. The following table provides a reconciliation of Net income (loss), on a GAAP basis, to EBITDA and EBITDA from continuing operations and Adjusted EBITDA from continuing operations, on a non-GAAP basis (in millions) Appendix A (in millions) Fiscal 2010 Fiscal 2014* Sales $388.7 $414 Net income (loss), on a GAAP basis $15.4 $-12.3 Add back: Provision (benefit) for income taxes 0.7 0.2 Interest Expense 0.7 2.1 Depreciation and amortization 13.2 24 EBITDA $30 $14.1 Other income (expense) Income (loss) from discontinued operations -2 -1.1000000000000001 EBITDA from continuing operations $32 $15.2 EBITDA Margin from continuing operations 8.2% 3.7% * Column does not foot due to rounding
