17.    LEASES

We have operating leases and to a lesser extent finance leases, for buildings, vehicles and equipment. Our leases have remaining lease terms of 1 year to 16 years, which includes our determination to exercise renewal options.

The components of lease expense were as follows (in millions):
Year Ended December 31,
202220212020
Operating lease cost$57.5 $53.2 $45.4

  Interest on lease liabilities0.8 0.8 0.8 
        Total finance lease cost$1.2 $1.3 $1.4 
Sublease income$3.0 $3.0 $3.0 

The sublease is for a building with a term that ends in 2025, with no options to extend or renew.

Operating lease cost includes original reduction in the carrying amount of right-of-use assets, the impact of remeasurements, modifications, impairments and abandonments.

Our short-term leases are expensed as incurred, reflecting leases with a lease term of one year or less, and are not significant for the years ended December 31, 2022, 2021 and 2020. Operating lease variable cost is primarily comprised of reimbursed actual common area maintenance, property taxes and insurance, which are immaterial for the years ended December 31, 2022, 2021 and 2020.

The value of our operating lease portfolio is principally for facilities with longer durations than the lesser value vehicles and other equipment with shorter terms and higher-turn over.

As of December 31, 2022, operating leases that have not commenced are not material.

About Leases Disclosures

Lease disclosures under ASC 842 provide a comprehensive view of a company's leased asset portfolio, including the split between operating and finance leases, discount rates used to present-value future payments, and the maturity schedule of lease obligations. This section reveals a significant source of off-balance-sheet commitments that were largely hidden before the current standard.

Key signals: the weighted-average discount rate affects the size of recorded lease liabilities — a higher rate reduces the reported obligation, so compare the chosen rate against the company's incremental borrowing rate. The operating versus finance lease mix affects both EBITDA and operating income presentation. Watch the maturity table for concentration risk: large payment cliffs in specific years may create cash flow pressure. Variable lease payments excluded from the liability measurement represent real obligations that do not appear on the balance sheet. Compare total lease costs against prior-year operating lease expense to assess the true economic burden.
