NOTE 12. LEASES

The following table presents our lease costs:

	2023		2022		2021
Operating lease cost	$	8.5	$	7.0	$	6.4
Finance lease cost:
Amortization of leased assets	$	3.1	$	2.4	$	2.4
Interest on lease liabilities		0.9		0.6		0.7
Total finance lease cost	$	4.0	$	3.0	$	3.1

Short-term lease expense and variable lease cost were not material for the years ended December 31, 2023, 2022 and 2021 and are excluded from the table above. As of December 31, 2023, we did not have any material leases that have not yet commenced.

The following table presents supplemental cash flow information related to our leases:

	2023		2022		2021
Cash paid for amounts included in the measurement of lease liabilities
Operating cash flows from operating leases	$	8.0	$	6.8	$	6.3
Operating cash flows from finance leases		0.8		0.6		0.7
Financing cash flows from finance leases		2.7		2.2		2.1
ROU assets obtained in exchange for lease liabilities
Operating leases (1)	$	15.8	$	3.9	$	7.3
Finance leases (2)		12.3		-		0.3

(1)The year ended December 31, 2023 included a decrease of $1.0 million in ROU assets due to a change in lease classification upon modification and an increase of $0.6 million resulting from modifications that did not involve obtaining a new ROU asset. The years ended December 31, 2022 and 2021 included increases in ROU assets of $1.0 million and $3.2 million, respectively, resulting from modifications that did not involve obtaining a new ROU asset. Modifications resulted primarily from changes in the terms of existing leases.

(2)The year ended December 31, 2023 included increases in ROU assets of $8.6 million due to the change in lease classification upon modification for an existing manufacturing facility within our Architectural Specialties segment which had a modified expected lease term of 13 years, in addition to an increase of $3.7 million for a lease modification that did not involve obtaining a new ROU asset.

During 2023, we entered into a new operating lease for a manufacturing facility within our Architectural Specialties segment which, upon commencement, resulted in an initial ROU asset and lease liability of $13.0 million based on an expected lease term of approximately 5 years.

The following table presents the weighted average assumptions used to compute our ROU assets and lease liabilities:

	December 31, 2023			December 31, 2022
Weighted average remaining lease term (in years)
Operating leases		4.8			5.1
Finance leases		9.5			9.4
Weighted average discount rate
Operating leases		5.7	%		3.8	%
Finance leases		4.7	%		3.7	%

Undiscounted future minimum lease payments as of December 31, 2023, by year and in the aggregate, having non-cancelable lease terms in excess of one year are as follows:

	Operating Leases			Finance Leases
Maturity of lease liabilities
2024	$	7.9		$	4.2
2025		6.6			4.0
2026		5.3			4.2

2028		3.5			2.5
Thereafter		2.5			14.3
Total lease payments		30.8			33.6
Less interest		(3.6	)		(7.2	)
Present value of lease liabilities	$	27.2		$	26.4
