The Company leases certain property, plant and equipment under operating leases, primarily consisting of railroad equipment leases.  Net minimum future rental payments due under non-cancelable operating leases with remaining terms in excess of one year as of December 31, 2018 are as follows:

2019	$	15,331
2020		16,893

2022		12,562

Leases of railroad equipment generally provide for renewal options at their fair rental value at the time of renewal.  In the normal course of business, operating leases for railroad equipment are generally renewed or replaced by other leases.  However, we expect to reduce our fleet of railcars as our current railcar leases expire.  Rent expense for all operating leases was $16,936 in 2018 and $20,310 in 2017.   For the years ended December 31, 2018 and 2017, rent expense was stated net of sublease income of $4,142 and $3,040, respectively.
