The Company leases parking facilities, office space, warehouses, vehicles and equipment and determines if an arrangement is a lease at inception. The Company subleases certain real estate to third parties. The Company's sublease portfolio consists of operating leases for space within leased parking facilities.

The Company accounts for leases in accordance with Topic 842. Operating lease ROU assets and lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term. ROU assets represent the Company's "right-of-use" over an underlying asset for the lease term, and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets include cumulative prepaid or accrued rent, as well as lease incentives, initial direct costs and acquired lease contracts. The short term lease exception has been applied to leases with an initial term of 12 months or less and these leases were not recorded within the Condensed Consolidated Balance Sheets.

As most of the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The Company uses the implicit rate when readily determinable. Lease expense is recognized on a straight-line basis over the lease term.

For leases that include one or more options to renew, the exercise of such renewal options is at the Company's sole discretion or mutual agreement. The Company’s lease term may include renewal options that are at the Company’s sole discretion and are reasonably certain to be exercised. Equipment and vehicle leases may also include options to purchase the leased property. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise.

Variable lease components comprising of payments that are a percentage of parking services revenue based on contractual levels and rental payments adjusted periodically for inflation are not included in the lease liability. The Company's lease agreements do not contain any material residual value guarantees or material restrictive covenants.

As discussed in Note 1. Significant Accounting Policies and Practices, the Company tests ROU assets when impairment indicators are present.

In April 2020, the FASB provided accounting elections for entities that receive or provide lease-related concessions to mitigate the economic effects of COVID-19 on lessees. The Company elected not to evaluate whether certain concessions provided by lessors in response to COVID-19, that are within the scope of additional interpretation provided by the FASB in April 2020, were lease modifications and also elected not to apply modification guidance under Topic 842. These concessions are recognized as a reduction of rent expense in the month they occurred and were recorded in Cost of services – lease type contracts within the Condensed Consolidated Statements of Income.

As a result of COVID-19, the Company has been able to negotiate lease concessions with certain landlords. These rent concessions were recorded in accordance with the guidance noted above. As a result, the Company recorded $1.5 million and $3.7 million related to rent concessions as a reduction to Cost of services – lease type contracts during the three and six months ended June 30, 2022, respectively. The Company recorded $6.1 million and $11.1 million related to rent concessions as a reduction to cost of services during the three and six months ended June 30, 2021, respectively.

Costs associated with the right to use the infrastructure on service concession arrangements are recorded as a reduction of revenue in accordance with the scope of ASU No. 2017-10, Service Concession Arrangements (Topic 853): Determining the Customer of the Operation Services. See Note 4. Revenue for further discussion on service concession arrangements.
