Adient manages its business on a geographic basis and operates in the following three reportable segments for financial reporting purposes: 1) Americas, which is inclusive of North America and South America; 2) Europe, the Middle East and Africa ("EMEA") and 3) Asia Pacific/China ("Asia").

Adient evaluates the performance of its reportable segments using an adjusted EBITDA metric defined as income before income taxes and noncontrolling interests, excluding net financing charges, qualified restructuring and impairment costs, restructuring related-costs, net mark-to-market adjustments on pension and postretirement plans, transaction gains/losses, purchase accounting amortization, depreciation, stock-based compensation and other non-recurring items. Also, certain corporate-related costs are not allocated to the segments. The reportable segments are consistent with how management views the markets served by Adient and reflect the financial information that is reviewed by its chief operating decision maker.

Since all companies do not use identical calculations, our definition and presentation of these measures may not be comparable to similarly titled measures reported by other companies. Management uses the identified non-GAAP measures to evaluate the operating performance of the Company and its business segments and to forecast future periods.

Investors should not consider these non-GAAP measures as alternatives to the related GAAP measures. Reconciliations of non-GAAP measures to their closest U.S. GAAP equivalent are presented below.
