11. Commitments and Contingencies

Legal Matters. From time to time, we have been and may again become involved in legal proceedings arising in the ordinary course of our business. We are not presently a party to any litigation that we believe to be material and we are not aware of any pending or threatened litigation against us that we believe could have a material adverse effect on our business, operating results, financial condition or cash flows.

Leases. During the year ended December 31, 2012, the Company entered into a six year software license agreement. The Company concluded that the software license agreement qualified as a capital lease. Accordingly, at June 30, 2016 and December 31, 2015, the Company had capital lease liabilities of $0.1 million and $0.2 million, respectively, included in accounts payable and accrued liabilities and other long-term liabilities on its consolidated balance sheet.

The Company has an operating lease for its office, research, and production facility in Englewood, Colorado with a term expiring in July 2021. The Company also maintains a corporate apartment in Colorado, which has a lease term expiring during the next 12 months. The Company has an operating lease for the rail cars used by Agri-Energy in Luverne, Minnesota.

Rent expense for the six months ended June 30, 2016 and years ended December 31, 2015 and 2014 was $0.2 million, $0.5 million and $0.5 million, respectively. The Company recognizes rent expense on its operating leases on a straight-line basis.

Indemnifications. In the ordinary course of its business, the Company makes certain indemnities under which it may be required to make payments in relation to certain transactions. As of June 30, 2016 and December 31, 2015, the Company did not have any liabilities associated with indemnities.

The Company, as permitted under Delaware law and in accordance with its amended and restated certificate of incorporation and amended and restated bylaws, indemnifies its officers and directors for certain events or occurrences, subject to certain limits, while the officer or director is or was serving at the Company’s request in such capacity. The duration of these indemnifications, commitments, and guarantees varies and, in certain cases, is indefinite. The maximum amount of potential future indemnification is unlimited; however, the Company has a director and officer insurance policy that may enable it to recover a portion of any future amounts paid. The Company accrues for losses for any known contingent liability, including those that may arise from indemnification provisions, when future payment is probable. No such losses have been recorded to date.

Environmental Liabilities. The Company’s operations are subject to environmental laws and regulations adopted by various governmental authorities in the jurisdictions in which it operates. These laws require the Company to investigate and remediate the effects of the release or disposal of materials at its locations. Accordingly, the Company has adopted policies, practices and procedures in the areas of pollution control, occupational health and the production, handling, storage and use of hazardous materials to prevent material environmental or other damage, and to limit the financial liability which could result from such events. Environmental liabilities are recorded when the Company’s liability is probable and the costs can be reasonably estimated. No environmental liabilities have been recorded as of June 30, 2016 or as of December 31, 2015.
