7. LEASES, OTHER COMMITMENTS, AND CONTINGENCIES

Litigation and Claims

We are not currently a party to any material pending legal proceeding.

Leases

We lease our headquarters facility, office equipment, and other items. Our headquarters lease involved the sale of land and improvements to a third party who then constructed the facility. The lease term is twenty years and we hold four five-year options to extend the lease.

Rent expense from all operating leases was $49 thousand for three months ended 2019, and $81 thousand for three months ended 2018.

Sale-Leaseback of Equipment

In December 2018 we consummated a sale-leaseback transaction with a third party to finance equipment. The lease has a term of four years and we may add up to $1.1 million of future equipment purchases to the financing agreement. We were required to deposit cash into a restricted account in an amount equal to the future rent payments required by the lease. At March 31, 2019, this restricted cash totaled $1.5 million.

Other Commitments

As of March 31, 2019, we have committed to purchase grain from farmers at dates throughout 2019 and 2020 aggregating $19.7 million using commodity futures market prices, other payments to growers and estimated yields per acre. This amount is not recorded in the financial statements because we have not taken delivery of the grain as of that date.
