(6) Leases

Tripadvisor’s lease contracts contain both lease and non-lease components which Tripadvisor combines as a single component under its accounting policy by asset class, except for office space leases and certain other leases, such as colocation data center leases, which it accounts separately for the lease and non-lease components. Additionally, for certain equipment leases that have similar characteristics, Tripadvisor applies a portfolio approach to effectively account for operating lease right-of-use (“ROU”) assets and lease liabilities.

Operating Leases

Tripadvisor leases office space in a number of countries around the world generally under non-cancelable lease agreements. Tripadvisor’s office space leases, exclusive of its corporate headquarters, are operating leases. Operating lease ROU assets and liabilities are recognized at the lease commencement date, or the date the lessor makes the leased asset available for use, based on the present value of the lease payments over the lease term using Tripadvisor’s estimated incremental borrowing rate.

Tripadvisor’s office space operating leases expire at various dates with the latest maturity in October 2034. These leases generally include options to extend the lease term for up to approximately 5 years and/or terminate the leases within 1 year, which Tripadvisor includes in the lease terms if it is reasonably certain to exercise these options.

Tripadvisor also establishes assets and liabilities at the present value of estimated future costs to return certain of its leased facilities to their original condition to satisfy any asset retirement obligations. Such assets are depreciated over the lease period into operating expense, and the recorded liabilities are accreted to the future value of the estimated restoration costs and are included in other liabilities on the consolidated balance sheet. Tripadvisor’s asset retirement obligations were not material as of both December 31, 2023 and 2022.

Finance Lease

Finance lease ROU assets and finance lease liabilities are recognized at the lease commencement date or the date the lessor makes the leased asset available for use. Finance lease ROU assets are generally amortized on a straight-line basis over the lease term, and the carrying amount of the finance lease liabilities are (1) accreted to reflect interest using the incremental borrowing rate if the rate implicit in the lease is not readily determinable, and (2) reduced to reflect lease payments made during the period. Amortization expense for finance lease ROU assets and interest accretion on finance lease liabilities are recorded to depreciation and interest expense, respectively, in the consolidated statements of operations.

Tripadvisor leases approximately 280,000 square feet of office space for its corporate headquarters in Needham, Massachusetts. This lease has an expiration date of December 2030, with an option to extend the lease term for two consecutive terms of five years each, and is accounted for as a finance lease.
