The Company’s leases are considered operating leases and primarily consist of real estate such as office space, broadcasting towers, land and land easements. An ROU asset and lease liability is recognized as of lease commencement date based on the present value of the future minimum lease payments over the lease term. As the implicit rate for operating leases is not readily determinable, the future minimum lease payments were discounted using an incremental borrowing rate. Due to the Company having a centralized treasury function, the Company applied a portfolio approach to discount its domestic lease obligations using its secured publicly traded U.S. dollar denominated debt instruments interpolating the duration of the debt to the remaining lease term. The incremental borrowing rate for international leases is the interest rate that the Company would have to pay to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment.

The Company’s operating leases are reflected within the consolidated balance sheet as right-of-use assets with the related liability presented as lease liability, current and lease liability, net of current portion. Lease expense is recognized on a straight-line basis over the lease term.

Generally, lease terms include options to renew or extend the lease. Unless the renewal option is considered reasonably certain, the exercise of any such options have been excluded from the calculation of lease liabilities. In addition, as permitted within the guidance, ROU assets and lease liabilities are not recorded for leases within an initial term of one year or less. The Company’s existing leases have remaining terms of less than one year up to 32 years. Certain of the Company’s lease agreements include rental payments based on changes in the CPI. Lease liabilities are not remeasured as a result of changes in the CPI; instead, changes in the CPI are treated as variable lease payments and recognized in the period in which the related obligation was incurred. Lease agreements do not contain any material residual value guarantees or material restrictive covenants.

Certain real estate leases include additional costs such as common area maintenance (non-lease component), as well as property insurance and property taxes. These costs were excluded from future minimum lease payments as they are variable payments. As such, these costs were not part of the calculation of ROU assets and lease liabilities associated with operating leases upon transition.
