Leases (Notes)

12 Months Ended

Dec. 31, 2019

We adopted a comprehensive new lease accounting standard effective January 1, 2019. The details of the significant changes to our accounting policies resulting from the adoption of the new standard are set out below. We adopted the standard using the optional modified retrospective transition method; accordingly, the comparative information as of December 31, 2018 and for the years ended December 31, 2018 and 2017 have not been adjusted and continue to be reported under the previous lease standard. Under the new lease standard, assets and liabilities that arise from all leases are required to be recognized on the balance sheet for lessees. Previously, only capital leases, which are now referred to as finance leases, were recorded on the balance sheet. The adoption of this standard resulted in the recognition of approximately $1.0 billion of operating lease right-of-use assets and operating lease liabilities on our consolidated balance sheets as of January 1, 2019. The adoption of this standard did not materially impact our consolidated results of operations for the year ended December 31, 2019. See Note 17 for additional information about the new accounting standard.

Beginning January 1, 2019, for all leases with a term in excess of 12 months, we recognized a lease liability equal to the present value of the lease payments and a right-of-use asset representing our right to use the underlying asset for the lease term. For operating leases, lease expense for lease payments is recognized on a straight-line basis over the lease term, while finance leases include both an operating expense and an interest expense component. For all leases with a term of 12 months or less, we elected the practical expedient to not recognize lease assets and liabilities. We recognize lease expense for these short-term leases on a straight-line basis over the lease term.

We are a lessee for numerous operating leases, primarily related to real estate, transportation and equipment. The vast majority of our operating leases have remaining lease terms of 10 years or less, some of which include options to extend the leases, and some of which include options to terminate the leases. We generally do not include renewal or termination options in our assessment of the leases unless extension or termination for certain assets is deemed to be reasonably certain. The accounting for some of our leases may require judgment, which includes determining whether a contract contains a lease, determining the incremental borrowing rates to utilize in our net present value calculation of lease payments for lease agreements which do not provide an implicit rate, and assessing the likelihood of renewal or termination options. We also have some lease agreements with lease and non-lease components, which are generally accounted for as a single lease component. For certain equipment leases, such as offshore vessels and drilling rigs, we account for the lease and non-lease components separately.

The following tables illustrate the financial impact of our leases as of and for the year ended December 31, 2019, along with other supplemental information about our existing leases:
