The Company’s leases do not contain residual value guarantees, material restrictions or covenants. During the year ended December 31, 2021, the Company subleased one of its facilities in San Francisco, California. The sublease agreement expires in 2024 and (i) does not include renewal and termination options, (ii) provides for customary escalations of lease payments in the normal course of business, and (iii) grants the subtenant certain allowances, such as free rent.

During the year ended December 31, 2022, the Company recorded $3.7 million of ROU asset impairments and $1.3 million of leasehold improvement impairments related to closing one floor of its offices located at 150 Spear Street, San Francisco, California. The space had been vacant prior to the Company electing to permanently reduce its office space. The impairments are included in restructuring costs in the Consolidated Statements of Income. During the year ended December 31, 2020, the Company recorded $2.3 million of ROU asset impairments and $1.1 million of leasehold improvement impairments related to a facility lease from the SiriusDecisions acquisition in 2019 that the Company no longer used as a result of the integration of SiriusDecisions. The impairments are included in integration costs in the Consolidated Statements of Income. The leasehold improvements were originally recorded in property and equipment, net in the Consolidated Balance Sheets. As a result of the impairments, the ROU asset and leasehold improvements were required to be recorded at their estimated fair value as Level 3 non-financial assets. The fair value of the asset group was determined using a discounted cash flow model, which required the use of estimates, including projected cash flows for the related assets, the selection of a discount rate used in the model, and regional real estate industry data. The fair value of the asset group was allocated to the ROU asset and leasehold improvements based on their relative carrying values.

During the fourth quarter of 2020, the Company received a variable incentive payment of $3.5 million from one of its landlords to terminate the related office space lease early. This amount was recognized as a reduction in variable lease expense.
