Leases
The company leases certain facilities, parcels of land, and equipment, with remaining terms ranging from less than one year to approximately 13.4 years. The land and facility leases include renewal options. The renewal options are included in the lease term only for those sites or locations in which they are reasonably certain to be renewed. Equipment renewals are not considered reasonably certain to be exercised as they typically renew with significantly different underlying terms.

Other Commitments
As of June 30, 2024, the company had contracted future purchases of grain, distillers grains and natural gas valued at approximately $163.3 million and future commitments for storage and transportation, valued at approximately $19.8 million.
The company has entered into contracts with Tallgrass High Plains Carbon Storage, LLC and its affiliates, related to the construction, development and operation of carbon capture and sequestration projects at our three Nebraska plants, which are expected to be completed in 2025. Payments associated with these contracts are due monthly over a period of twelve years, commencing after the capture facilities are considered in-service. Amounts due under the contracts are based on the achievement of certain project milestones and are subject to termination of all or portions of the contracts. Certain of the future obligations to Tallgrass High Plains Carbon Storage LLC are secured by a leasehold deed of trust, security agreement and assignment of rents and leases.
Legal
The company is currently involved in litigation that has arisen in the ordinary course of business, but does not believe any pending litigation will have a material adverse effect on its financial position, results of operations or cash flows.
