Operating Leases

TripCo’s consolidated companies have contractual obligations in the form of operating leases for office and warehouse space for which the related expense is recorded on a monthly basis. Certain leases contain periodic rent escalation adjustments and renewal options. Rent expense related to such leases is recorded on a straight-line basis. Operating lease obligations expire at various dates with the latest maturity in December 2030.

In June 2013, TripAdvisor entered into a lease to move its headquarters to Needham, Massachusetts in 2015. TripAdvisor was the deemed owner (for accounting purposes only) of the new building during the construction period under build to suit lease accounting. As building construction began in the fourth quarter of 2013, TripAdvisor recorded project construction costs incurred by the landlord as a construction-in-progress asset and a corresponding construction financing obligation in “Property and equipment, at cost” and “Other liabilities,” respectively, in the consolidated balance sheets.

Upon completion of construction at the end of the second quarter of 2015, TripAdvisor evaluated the construction-in-progress asset and construction financing obligation for de-recognition under the criteria for “sale-leaseback” treatment under GAAP. TripAdvisor has continued economic involvement in the facility, and therefore did not meet the provisions for sale-leaseback accounting. This determination was based on TripAdvisor's continuing involvement with the property in the form of non-recourse financing to the lessor. Therefore, the lease has been accounted for as a financing obligation. Accordingly, TripAdvisor began depreciating the building asset over its estimated useful life and incurring interest expense related to the financing obligation imputed using the effective interest rate method. TripAdvisor bifurcates the lease payments into (i) a portion that is allocated to the building (a reduction to the construction financing obligation) and; (ii) a portion that is allocated to the land on which the building was constructed. The portion of the lease payments allocated to the land is treated as an operating lease that commenced in 2013. The lease costs allocated to the land are recognized as rent expense on a straight-line basis over the term of the lease and are recorded in general and administrative expense in the consolidated statements of operations. The construction financing obligation is considered a long-term finance lease obligation and is recorded to noncurrent “Other liabilities” in the consolidated balance sheets.  At the end of the lease term, the carrying value of the building asset and of the remaining financing obligation are expected to be equal, at which time TripAdvisor may either surrender the leased asset as settlement of the remaining financing obligation or extend the initial term of the lease for the continued use of the asset. TripAdvisor incurred approximately $6 million of non-cash construction costs and related obligations in connection with the capitalization of construction-in-progress and tenant improvement costs during the year ended December 31, 2015.

TripAdvisor also leases an aggregate of approximately 450,000 square feet at approximately 40 other locations across North America, Europe and Asia Pacific, primarily for its international management teams, sales offices, and subsidiary headquarters, pursuant to leases with expiration dates through June 2027.

For the years ended December 31, 2017,  2016 and 2015, TripCo recorded rental expense of $19 million, $21 million and $22 million, respectively. The following table presents TripCo’s estimated future minimum rental payments under operating leases with non-cancelable lease terms, including TripAdvisor’s headquarters lease, that expire after December 31, 2017 (amounts in millions):

Off-Balance Sheet Arrangements

TripCo did not have any other off-balance sheet arrangements that have, or are reasonably likely to have, a current or future effect on the Company’s financial condition, results of operations, liquidity, capital expenditures or capital resources.

Litigation

In the ordinary course of business, the Company and its subsidiaries are parties to legal proceedings and claims arising out of our operations. These matters may relate to claims involving alleged infringement of third-party intellectual property rights, defamation, taxes, regulatory compliance and other claims. Although it is reasonably possible that the Company may incur losses upon conclusion of such matters, an estimate of any loss or range of loss cannot be made. In the opinion of management, it is expected that amounts, if any, which may be required to satisfy such contingencies will not be material in relation to the accompanying consolidated financial statements.
