Our Mission & Vision 29 Appendix

Our Mission & Vision 30 Reconciliation of Adjusted EBITDA Consolidated Note : Data shown based on NCI fiscal year end. ( 1) Adjusted EBITDA is defined as net income (loss) before interest expense, income tax expense (benefit) and depreciation and am ort ization, adjusted for items broadly consisting of selected items which management does not consider representative of ongoing operations and certain non - cash items of the Company , including charges for goodwill and other asset impairment and stock compensation. As such, the historical information is presented above in accordance with this definition. The Company discloses Adjusted EBITDA, which is a non - GAAP measure, because it is used by management and provided to investors to provide comparability of underlying operational results .
