The Company leases, under finance and operating lease arrangements, certain facilities used primarily in the Asset-Based segment service center operations, certain revenue equipment used in the ArcBest segment operations, and certain other office equipment. Current operating leases have remaining terms of less than 10 years, some of which include one or more options to renew, with renewal option terms up to five years, and some of which include options to terminate the leases within the next two years. The right-of-use assets and lease liabilities as of December 31, 2019 do not assume the option to early terminate any of the Company’s leases, and all renewal options that have been exercised or are reasonably certain to be exercised as of December 31, 2019 are included in the right-of-use assets and lease liabilities. Variable lease cost for operating leases consists of subsequent changes in CPI index, rent payments that are based on usage, and other lease related payments which are subject to change and not considered fixed payments. All fixed lease and non-lease component payments are combined in determining the right-of-use asset and lease liability.

(1)	Operating lease expense excludes short-term leases with a term of 12 months or less.

Rental expense for operating leases, excluding expenses related to leases with initial terms of less than one year, totaled $20.5 million, net of sublease income, for 2018 and 2017.
