OPERATIONS BY REPORTING SEGMENT The Company operates with two end-customer focused business segments. The Powertrain segment focuses on original equipment products for automotive, heavy duty and industrial applications. The Motorparts segment sells and distributes a broad portfolio of products in the global aftermarket, while also serving original equipment manufacturers with products including braking, chassis, wipers and other vehicle components. This organizational model allows for a strong product line focus benefitting both original equipment and aftermarket customers and enables the Company's global teams to be responsive to customers  needs for superior products and to promote greater identification with the Company's premium brands. Additionally, this organizational model enhances management focus to capitalize on opportunities for organic or acquisition growth, profit improvement, resource utilization and business model optimization in line with the unique requirements of the two different customer bases. The Company evaluates reporting segment performance principally on a non-GAAP Operational EBITDA basis. Management believes that Operational EBITDA provides supplemental information for management and investors to evaluate the operating performance of its business. Management uses and believes that investors benefit from referring to Operational EBITDA in assessing the Company s operating results, as well as in planning, forecasting and analyzing future periods as this financial measure approximates the cash flow associated with the operational earnings of the Company. Additionally, Operational EBITDA presents measures of corporate performance exclusive of capital structure and the method by which assets were acquired and financed. Accordingly, operational EBITDA is defined as earnings from continuing operations before interest, income taxes, depreciation and amortization, and certain items such as restructuring and impairment charges, Chapter 11 and U.K. Administration related reorganization expenses,
