17.  Operating and Finance Lease Liabilities

​

As of June 30, 2023, the Company had operating leases, as lessee, primarily associated with sale/leaseback transactions that are partially secured by restricted cash and security deposits (see also Note 19, “Commitments and Contingencies”) as summarized below.  These leases expire over the next one to nine years. Minimum rent payments under operating leases are recognized on a straight-line basis over the term of the lease.  

​

Leases contain termination clauses with associated penalties, the amount of which cause the likelihood of cancellation to be remote.  At the end of the lease term, the leased assets may be returned to the lessor by the Company, the Company may negotiate with the lessor to purchase the assets at fair market value, or the Company may negotiate with the lessor to renew the lease at market rental rates.  No residual value guarantees are contained in the leases.  No financial covenants are contained within the lease; however, the lease contains customary operational covenants such as the requirement that the Company properly maintain the leased assets and carry appropriate insurance. The leases include credit support in the form of either cash, collateral or letters of credit.  See Note 19, “Commitments and Contingencies” for a description of cash held as security associated with the leases.

The Company has finance leases associated with its property and equipment in Latham, New York and at fueling customer locations.  The fair value of this finance obligation approximated the carrying value as of June 30, 2023.
