Leases [Abstract]

LEASES

LEASES

Our portfolio of nonmineral leases is composed of leases for real estate (including office buildings, aggregates sales yards and terminals, and concrete and asphalt sites) and equipment (including railcars and rail track, barges, and office, plant and mobile equipment).

Lease right-of-use (ROU) assets and liabilities and the weighted-average lease terms and discount rates are as follows:

in millions	Classification on the Balance Sheet	March 31 2024			December 31 2023			March 31 2023

The decreases from March 31, 2023 in total lease assets and liabilities presented above primarily relate to the November 2023 sale of concrete operations in Texas (see Note 16 for additional information). Our lease agreements do not contain material residual value guarantees, restrictive covenants or early termination options. In addition to the lease assets and liabilities presented in the table above, we entered into an agreement to lease a terminal in California and expect to have all permits in place associated with all lease commencement options by the middle of 2024.

The components of lease expense are as follows:

	Three Months Ended March 31
in millions	2024		2023
Finance lease cost
Depreciation of right-of-use assets	$	2.5	$	3.4
Interest on lease liabilities	0.2		0.2

Short-term lease cost 1	11.1		11.7
Variable lease cost	5.3		5.1
Sublease income	(0.8)		(0.8)
Total lease expense	$	37.1	$	39.0

1Includes the cost of leases with an initial term of one year or less (including those with terms of one month or less).

Cash paid for operating leases was $18.4 million and $18.3 million for the three months ended March 31, 2024 and 2023, respectively. Cash paid for finance leases (principal and interest) was $3.7 million and $6.1 million for the three months ended March 31, 2024 and 2023, respectively.
