Segment Information Our operating segments are aggregated into reportable business segments based primarily upon similar economic characteristics, products, services, customers, and delivery methods. We have identified two reportable segments: rental and leasing of cars, crossovers and light trucks, or  car rental,  and rental of industrial, construction and material handling equipment, or  equipment rental.  Other reconciling items includes general corporate assets and expenses, certain interest expense (including net interest on corporate debt), as well as other business activities, such as our third party claim management services. Adjusted pre-tax income (loss) is the measure utilized by management in making decisions about allocating resources to segments and measuring their performance. We believe this measure best reflects the financial results from ongoing operations. Adjusted pre-tax income (loss) is calculated as income (loss) before income taxes plus other reconciling items, non-cash purchase accounting charges, non-cash debt charges and certain one-time charges and non-operational items. The contribution of our reportable segments for the years ended December 31, 2012, 2011 and 2010 is summarized below (in millions of dollars).
