LEASES

12 Months Ended

Dec. 31, 2020

LEASESWe determine if a contract contains a lease by evaluating the nature and substance of the agreement. We lease facilities, computer hardware, and other furniture and equipment. Leases with an initial term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term. For new lease agreements, we combine lease and nonlease components for all of our asset classes.

When portions of the lease payments are not fixed or depend on an index or rate, we consider those payments to be variable in nature. Our variable lease payments include, but are not limited to, common area maintenance, taxes and insurance which are not dependent upon an index or rate. Variable lease payments are recorded in the period in which the obligation for the payment is incurred. Most leases include options to renew, with renewal terms that can extend the lease term. The exercise of lease renewal options is at our sole discretion. Certain leases 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. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants.

Right-of-use assets included within other long-term assets in our consolidated balance sheets were $437 million and $410 million at December 31, 2020 and 2019, respectively. Operating lease liabilities included within trade accounts payable and accrued expenses were $129 million and $116 million at December 31, 2020 and December 31, 2019, respectively. Additionally, operating lease liabilities included within other long-term liabilities were $355 million and $332 million at December 31, 2020 and December 31, 2019, respectively. The classification of our operating lease liabilities is based on the remaining lease term.

For the years ended December 31, 2020 and December 31, 2019, total fixed operating lease costs, excluding short-term lease costs, were $141 million and $154 million, respectively, and are included within operating costs in our consolidated statements of income. Short-term lease costs were not material for the years ended December 31, 2020 and December 31, 2019. In addition, for the years ended December 31, 2020 and December 31, 2019, total variable operating lease costs were $92 million and $82 million, respectively, and are included within operating costs in our consolidated statements of income.

We sublease facilities or partial facilities to third party tenants for space not used in our operations. For the years ended December 31, 2020 and December 31, 2019, sublease rental income was $36 million and $45 million, respectively, and is included within operating costs in our consolidated statements of income.

The weighted average remaining lease term is 5.2 years and 4.9 years with a weighted average discount rate of 3.7% and 4.1% at December 31, 2020 and December 31, 2019, respectively. For the year-ended December 31, 2020 and December 31, 2019, cash paid for amounts included in the measurement of lease liabilities included within our operating cash flows was $146 million and $151 million, respectively.
