8. LEASES

We enter into operating leases for many of our facilities, vehicle and equipment needs. These leases allow us to retain cash, and we pay a monthly lease rental fee. At the end of the lease, we have no further obligation to the lessor. We may cancel or terminate a lease before the end of its term. Typically, we would be liable to the lessor for various lease cancellation or termination costs and the difference between the fair market value of the leased asset and the implied book value of the leased asset as calculated in accordance with the lease agreement.

For a discussion of leases with certain related parties which are included below, see Note 12 “Related-Party Transactions.”

Rent expense was $7,680, $6,990 and $5,868 for the years ended September 30, 2018, 2017 and 2016, respectively.
