COMMITMENTS

We have entered into various operating lease agreements for office facilities and equipment, the last of which expires in fiscal 2026. The office facility leases generally require us to pay a pro-rata share of the lessor’s operating expenses. Certain operating leases contain escalation clauses and are being amortized on a straight-line basis over the term of the lease.

The following schedule reflects future minimum rental commitments at September 30, 2018 under noncancelable operating leases (in thousands):



Fiscal year	Amount
2019	$	1,986
2020	1,675
2021	1,235
2022	1,054
2023	833
Thereafter	1,836
Total minimum payments required	$	8,619

Subsequent to the end of the fiscal 2018, in October 2018, we signed a thirteen-year lease agreement with minimum lease obligations of $15.9 million with Colfin Midwest NNN Investor, LLC (see Note 18 to our Consolidated Financial Statements).
