rental expense for operating leases was approximately $ 300 million , $ 247 million , and $ 212 million during the years ended december 31 , 2018 , 2017 and 2016 , respectively . we guarantee the residual values of the majority of our truck and equipment operating leases . the residual values decline over the lease terms to a defined percentage of original cost . in the event the lessor does not realize the residual value when a piece of equipment is sold , we would be responsible for a portion of the shortfall . similarly , if the lessor realizes more than the residual value when a piece of equipment is sold , we would be paid the amount realized over the residual value . had we terminated all of our operating leases subject to these guarantees at december 31 , 2018 , our portion of the guaranteed residual value would have totaled approximately $ 76 million . we have not recorded a liability for the guaranteed residual value of equipment under operating leases as the recovery on disposition of the equipment under the leases is expected to approximate the guaranteed residual value . litigation and related contingencies we have certain contingencies resulting from litigation , claims and other commitments and are subject to a variety of environmental and pollution control laws and regulations incident to the ordinary course of business . we currently expect that the resolution of such contingencies will not materially affect our financial position , results of operations or cash flows. .
