Segment Information The Companys chief operating decision-maker assesses performance and allocates resources based upon the separate financial information from each of the Companys operating segments. In identifying its reportable segments, the Company considered the nature of services provided, the geographical areas in which the segments operated and other relevant factors. The Company aggregates certain of its operating segments into its reportable segments. Management evaluates the operating results of each of its reportable segments based upon revenues and Adjusted EBITDA, which the Company defines as income (loss) from continuing operations before non-vehicle related depreciation and amortization, any impairment charges, restructuring and other related charges, early extinguishment of debt costs, non-vehicle related interest, transaction-related costs, net charges for unprecedented personal-injury legal matters, non-operational charges related to shareholder activist activity, gain on sale of equity method investment in China, COVID-19 charges and income taxes. Net charges for unprecedented personal-injury legal matters and gain on sale of equity method investment in China are recorded within operating expenses in the Companys Consolidated Condensed Statement of Comprehensive Income. Non-operational charges related to shareholder activist activity include third party advisory, legal and other professional service fees and are recorded within selling, general and administrative expenses in the Companys Consolidated Condensed Statement of Comprehensive Income. COVID-19 charges include unusual, direct and incremental costs due to the COVID-19 global pandemic such as overflow parking for idle vehicles, incremental cleaning supplies to sanitize vehicles and facilities, and losses associated with vehicles damaged in overflow parking lots and are recorded within operating expenses in the Companys Consolidated Condensed Statement of Comprehensive Income. The Company has revised its definition of Adjusted EBITDA to exclude COVID-19 charges. The Company has not revised prior years' Adjusted EBITDA amounts because there were no other charges similar in nature to these. The Companys presentation of Adjusted EBITDA may not be comparable to similarly-titled measures used by other companies.
