(1) Janitorial arrangements provide a wide range of essential cleaning services for commercial office buildings, airports and other transportation centers, educational institutions, government buildings, health facilities, industrial buildings, retail stores, and stadiums and arenas. These arrangements are often structured as monthly fixed-price, square-foot, cost-plus, and work order contracts.

(2) Parking arrangements provide parking and transportation services for clients at various locations, including airports and other transportation centers, commercial office buildings, educational institutions, health facilities, hotels, and stadiums and arenas. These arrangements are structured as management reimbursement, leased location, and allowance contracts. Certain of these arrangements are considered service concession agreements and are accounted for under the guidance of Topic 853; accordingly, rent expense related to these arrangements is recorded as a reduction of the related parking service revenues.

(3) Facility Services arrangements provide onsite mechanical engineering and technical services and solutions relating to a broad range of facilities and infrastructure systems that are designed to extend the useful life of facility fixed assets, improve equipment operating efficiencies, reduce energy consumption, lower overall operational costs for clients, and enhance the sustainability of client locations. These arrangements are generally structured as monthly fixed-price, cost-plus, and work order contracts.

(4) Building & Energy Solutions arrangements provide custom energy solutions, including microgrid systems installation, electrical, HVAC, lighting, electric vehicle charging station installation, and other general maintenance and repair services for clients in the public and private sectors and are generally structured as Energy Savings and Fixed-Price Repair and Refurbishment contracts. We also franchise certain operations under franchise agreements relating to our Linc Network and TEGG brands pursuant to franchise contracts.

(5) Airline Services arrangements support airlines and airports with services such as passenger assistance, catering logistics, and airplane cabin maintenance. These arrangements are often structured as monthly fixed-price, cost-plus, transaction price, and hourly contracts.
