Leases [Abstract]  
Leases LeasesWe enter into lease arrangements primarily for real estate, project equipment, transportation and information technology assets in the normal course of our business operations. Real estate leases accounted for approximately 89% of our lease obligations at December 31, 2021. An arrangement is determined to be a lease at inception if it conveys the right to control the use of identified property and equipment for a period of time in exchange for consideration. We have elected not to recognize an ROU asset and lease liability for leases with an initial term of 12 months or less. Many of our equipment leases, primarily associated with the performance of projects for U.S. government customers, include one or more renewal option periods, with renewal terms that can extend the lease term in one year increments. The exercise of these lease renewal options is at our sole discretion and is generally dependent on the period of project performance, or extension thereof, determined by our customers. When it is reasonably certain that we will exercise the option, we include the impact of the option in the lease term to determine total future lease payments. Because most of our lease agreements do not explicitly state the discount rate, we use our incremental borrowing rate on the commencement date to calculate the present value of future lease payments.
Certain leases include payments that are based solely on an index or rate. These variable lease payments are included in the calculation of the ROU asset and lease liability. Other variable lease payments, such as usage-based amounts, are excluded from the ROU asset and lease liability, and are expensed as incurred. In addition to the present value of the future lease payments, the calculation of the ROU asset also includes any deferred rent, lease pre-payments and initial direct costs of obtaining the lease, such as commissions.

In addition to the base rent, real estate leases typically contain provisions for common-area maintenance and other similar services, which are considered non-lease components for accounting purposes. We exclude these non-lease components in calculating the ROU asset and lease liability for real estate leases and expense them as incurred. For all other types of leases, non-lease components are included in calculating our ROU assets and lease liabilities.

The operating ROU asset and current and noncurrent operating lease liabilities are disclosed on our consolidated balance sheets. The finance ROU asset is included in property, plant and equipment and the current and noncurrent finance lease liabilities are included in other current liabilities and other liabilities, respectively, on our consolidated balance sheets.

The components of our operating lease costs for the years ended December 31, 2021, 2020 and 2019 were as follows:

Operating lease cost includes operating lease ROU asset amortization of $38 million, $37 million and $38 million for the years ended December 31, 2021, 2020 and 2019, respectively, and other noncash operating lease costs related to the accretion of operating lease liabilities and straight-line lease accounting of $13 million for the years ended December 31, 2021 and 2020 and $16 million for the year ended December 31, 2019.

Total short-term lease commitments as of December 31, 2021 were approximately $416 million. Additional information related to leases was as follows:
