Segment Reporting [Abstract]

Segment Information

17. Segment Information

Segment information is presented in accordance with a “management approach,” which designates the internal reporting used by the Company's Chief Operating Decision Maker (“CODM”) for making decisions and assessing performance as the source of the Company’s reportable segments. The Company’s segments are organized in a manner consistent with which discrete financial information is available and evaluated regularly by the CODM in deciding how to allocate resources and assess performance.

An operating segment is defined as a component of an enterprise that engages in business activities from which it may earn revenue and incur expenses, and about which separate financial information is regularly evaluated by the CODM. The CODM is the Company’s chief executive officer.

Each of the operating segments are directly responsible for revenue and expenses related to their operations, including direct segment general and administrative expenses. The CODM assesses the performance of each operating segment using information about operating income (loss) as its primary measure of performance, but does not evaluate segments using discrete asset information. Therefore, assets are not presented at the segment level. There were no material inter-segment transactions during the years ended December 31, 2023, 2022 and 2021, and the Company does not allocate other expense (income), interest expense (income) or income tax expense (benefit) to the operating segments. The accounting policies for segment reporting are the same as for the Company as a whole.

The Company’s operating segments are Commercial and Aviation:

•Commercial encompasses the Company's services in healthcare facilities, municipalities, including meter revenue collection and enforcement services, government facilities, hotels, commercial real estate, residential communities, retail, colleges and universities, as well as ancillary services such as providing technology-based mobility solutions, shuttle and ground transportation services, valet services, taxi and livery dispatch services and event planning, including shuttle and transportation services.

•Aviation encompasses the Company's services in aviation (i.e., airports, airline and certain hospitality clients with baggage and parking services) as well as ancillary services, which includes shuttle and ground transportation services, valet services, baggage handling, baggage repair and replacement, remote air check-in services, wheelchair assist services and other services, as well as providing technology-based mobility solutions.

The Other segment includes costs related to the Company's operational support teams and costs related to common and shared infrastructure, including finance, accounting, information technology, human resources, purchasing, legal and corporate development.
