We recorded impairment charges of approximately $115.4 million related to the write down of value in the sand railcar fleet to their estimated fair value. These charges relate mainly to the Oil & Gas Segment and are recorded in "Goodwill and other asset impairments" in the Consolidated Statements of Operations. See Note Z - Impairments for additional information.

Operating lease liabilities are based on the net present value of the remaining lease payments over the remaining lease term. As most of our leases do not provide an implicit rate, in determining the lease liability and the present value of lease payments, we used our incremental borrowing rate based on the information available at the lease commencement date. The weighted average remaining lease term and discount rate as of December 31, 2019 related to leases are as follows:

Lease Term and Discount Rate
