Leases [Abstract]

Leases

Note 2.  Leases

We determine if an arrangement is a lease at inception.  The Company has operating leases for premises, equipment, rail cars and automobiles.  Our leases have remaining lease terms of 1 year to 50 years, some of which may include options to extend the leases further. The Company considers these options in determining the lease term used to establish the right-of-use assets and lease liabilities. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based upon the information available at commencement date, or as of implementation of ASC 842, in determining the present value of lease payments.

Leases with an initial term of 12 months or less are not recorded on the balance sheet. We recognize lease expense for these leases on a straight-line basis over the lease term. Certain lease agreements contain both lease and non-lease components. We account for lease components together with non-lease components.

Operating lease cost was $15.3 million, $15.3 million and $16.6 for the years ended December 31, 2021 , December 31, 2020 and December 31, 2019, respectively. The components of lease costs are as follows:
