Commitments and Contingencies Disclosure [Abstract]

Operating Leases

We are obligated under noncancelable operating leases for corporate office space, warehouse and distribution facilities, trucks and certain equipment.

In the second quarter of 2017, we entered into a lease for office space to be constructed for our field support center in Nashville, Tennessee. The commencement date is scheduled for the fourth quarter of 2018, with a lease term of 17 years and the option to renew and extend the lease for three consecutive renewal terms of five years each. Rent will escalate annually by 1.5% over the prior year's rent. Under the lease, we can exercise an early purchase option after the first year of the lease.

The future minimum lease commitments under these leases at September 30, 2017 are as follows (in thousands):

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.
