LEASES AND OTHER COMMITMENTS

Leases

There are two types of leases: finance and operating. Both types of leases have associated right-to-use assets and lease liabilities that are valued at the present value of the lease payments and recognized on the Unaudited Consolidated Statements of Financial Position. The discount rate used in the measurement of a right-to-use asset and lease liability is the rate implicit in the lease whenever that rate is readily determinable. If the rate implicit in the lease is not readily determinable, the collateralized incremental borrowing rate is used. The Company elected the accounting policy not to apply the recognition and measurement requirements to short-term leases with a term of 12 months or less and do not include a bargain purchase option.

The Company has operating leases, as a lessee, with customary terms that do not include: significant variable lease payments; significant reasonably certain extensions or options required to be included in the lease term; restrictions; or other covenants for real property, rolling stock, and machinery and equipment. Real property leases primarily consist of office space and rolling stock leases primarily for railcars and fleet vehicles. At March 31, 2021 and December 31, 2020, operating right-to-use assets of $177 million and $185 million, respectively, are included as a part of "Other noncurrent assets" in the Unaudited Consolidated Statements of Financial Position and includes $9 million at both periods of assets previously classified as lease intangibles and $8 million and $9 million of prepaid lease assets, respectively. Operating lease liabilities are included as a part of "Payables and other current liabilities" and "Other long-term liabilities" in the Unaudited Consolidated Statements of Financial Position.

As of March 31, 2021, reconciliation of lease payments and operating lease liabilities is provided below:


(Dollars in millions)	Operating lease liabilities
Remainder of 2021	$	46
2022	47
2023	33
2024	19
2025	12
2026 and beyond	28
Total lease payments	185
Less: amounts of lease payments representing interest	16
Present value of future lease payments	169
Less: current obligations under leases	55
Long-term lease obligations	$	114

The Company has operating leases, primarily leases for railcars, with terms that require the Company to guarantee a portion of the residual value of the leased assets upon termination of the lease that will expire beginning second quarter 2021. Residual guarantee payments that become probable and estimable are recognized as rent expense over the remaining life of the applicable lease. Management's current expectation is that the likelihood of material residual guarantee payments is remote.

Other Commitments

Supplier Purchase Obligations

The Company had various purchase obligations at March 31, 2021, totaling approximately $3.1 billion over a period of

approximately 30 years for materials, supplies, and energy incident to the ordinary conduct of business.

Guarantees

Guarantees and claims also arise during the ordinary course of business from relationships with customers, suppliers, joint venture partners, and other parties when the Company undertakes an obligation to guarantee the performance of others if specified triggering events occur. Non-performance under a contract could trigger an obligation of the Company. The Company's current guarantees relate to intellectual property, environmental matters, and other indemnifications and have arisen through the normal course of business. The ultimate effect on future financial results is not subject to reasonable estimation because considerable uncertainty exists as to the final outcome of these claims, if they were to occur. These guarantees have terms up to 30 years with maximum potential future payments of approximately $25 million in the aggregate, with none of these guarantees being individually significant to the Company's operating results, financial position, or liquidity. Management's current expectation is that future payment or performance related to non-performance under guarantees is remote.
