Operating Leases

We lease two facilities in Denver, CO and Oxnard, CA that are under operating leases through December 2018 and March 2020, respectively. Both of these leases require us to pay increases in real estate taxes, operating costs and repairs over certain base year amounts. Lease payments for the years ended December 31, 2017 and 2016 were $279,000 and $287,000, respectively.

Future minimum rental commitments under all non-cancelable operating leases are as follows (in thousands):
