8. Senior Secured Debt, Secured Debt and Convertible Notes

Senior Secured Debt

In May 2014, the Company entered into a term loan agreement (the “Loan Agreement”) with the lenders party thereto from time to time (each, a “Lender” and collectively, the “Lenders”) and Whitebox Advisors, LLC, as administrative agent for the Lenders (“Whitebox”), with a maturity date of June 23, 2017 (refer to Note 19 Subsequent Events for disclosure on our February 2017 agreement with the lender to extend the maturity date from March 15, 2017), pursuant to which the Lenders committed to provide one or more senior secured term loans to the Company in an aggregate amount of up to approximately $31.1 million on the terms and conditions set forth in the Loan Agreement (collectively, the “Term Loan”). The first advance of the Term Loan in the amount of $22.8 million (the “First Advance”), net of discounts and issue costs of $1.6 million and $1.5 million, respectively, was made to the Company in May 2014. Also in May 2014, the Company and its subsidiaries entered into an Exchange and Purchase Agreement (the “Exchange and Purchase Agreement”) with WB Gevo, Ltd. and the other Lenders party thereto from time to time and Whitebox, in its capacity as administrative agent for the Lenders. Pursuant to the terms of the Exchange and Purchase Agreement, the Lenders were given the right, subject to certain conditions, to exchange all or a portion of the outstanding principal amount of the Term Loan for the Company’s 2017 Notes (as defined below), which are convertible into shares of the Company’s common stock. While outstanding, the Term Loan bore an interest rate equal to 15% per annum, of which 5% was payable in cash and 10% was payable in kind and capitalized and added to the principal amount of the Term Loan.

In June 2014, the Lenders exchanged all $25.9 million of outstanding principal amount of Term Loan provided in the First Advance for 10% convertible senior secured notes due 2017 (the “2017 Notes” and, together with the 2022 Notes, the “Convertible Notes”), together with accrued paid-in-kind interest of $0.2 million. The terms of the 2017 Notes are set forth in an indenture by and among the Company, its subsidiaries in their capacity as guarantors, and Wilmington Savings Fund Society, FSB, as trustee (the “2017 Notes Indenture”).

The 2017 Notes were originally set to mature on March 15, 2017. However, upon the February 2017 Note Extension Transaction (see Note 19 Subsequent Events), the 2017 Notes are now set to mature on June 23, 2017. The 2017 Notes have a conversion price (the “Conversion Price”) equal to $344.83 per share or 0.0029 shares per $1 principal amount of 2017 Notes. Optional prepayment of the 2017 Notes will not be permitted. In addition, the February 2017 Note Extension amended the interest rate applicable to the 2017 Notes. The 2017 Notes now bear interest at a rate equal to 12% per annum, which is payable 6% in cash and, under certain circumstances, 6% in kind and capitalized and added to the principal amount of the 2017 Notes. While the 2017 Notes are outstanding, the Company is required to maintain an interest reserve in an amount equal to 10% of the original outstanding principal amount of $26.1 million, to be adjusted on an annual basis. As of December 31, 2016 and 2015, there was a balance of $2.6 million in the interest reserve account. This amount is classified as restricted deposits.

The 2017 Notes Indenture contains customary affirmative and negative covenants for agreements of this type and events of default, including, restrictions on disposing of certain assets, granting or otherwise allowing the imposition of a lien against certain assets, incurring certain amounts of additional indebtedness, making investments, acquiring or merging with another entity, and making dividends and other restricted payments, unless the Company receives the prior approval of the required holders. For the years ended December 31, 2016 and 2015, the Company was in compliance with the covenants. The 2017 Notes Indenture also contains limitations on the ability of the holder to assign or otherwise transfer its interest in the 2017 Notes. The 2017 Notes are secured by a lien on substantially all of the assets of the Company and is guaranteed by Agri-Energy and Gevo Development (together, the “Guarantor Subsidiaries” or “Guarantors”). On June 6, 2014, in connection with the issuance of the 2017 Notes, the Company and the Guarantor Subsidiaries entered into a Pledge and Security Agreement in favor of the collateral trustee. The collateral pledged includes substantially all of the assets of the Company and the Guarantor Subsidiaries, including intellectual property and real property. Agri-Energy has also entered into a mortgage with respect to the real property located in Luverne Minnesota.

The holders of the 2017 Notes may, at any time until the close of business on the business day immediately preceding the maturity date, convert the principal amount of the 2017 Notes, or any portion of such principal amount which is at least $1,000, into shares of the Company’s common stock. Upon conversion of the 2017 Notes, the Company will deliver shares of common stock at a conversion rate of 0.0029 shares of common stock per $1.00 principal amount of the 2017 Notes (equivalent to a conversion price of approximately $344.83 per share of common stock). Such conversion rate is subject to adjustment in certain circumstances, including in the event that there is a dividend or distribution paid on shares of the common stock or a subdivision, combination or reclassification of the common stock. The Company also has the right to increase the conversion rate (i) by any amount for a period of at least 20 business days if the Company’s board of directors determines that such increase would be in the Company’s best interest or (ii) to avoid or diminish any income tax to holders of shares of common stock or rights to purchase shares of common stock in connection with any dividend or distribution. In addition, subject to certain conditions described herein, each holder who exercises its option to voluntarily convert its 2017 Notes will receive a make-whole payment in an amount equal to any unpaid interest that would otherwise have been payable on such 2017 Notes through the maturity date (a “Voluntary Conversion Make-Whole Payment”). Subject to certain limitations, the Company may pay any Voluntary Conversion Make-Whole Payments either in cash or in shares of common stock, at its election.

The Company has the right to require holders of the 2017 Notes to convert all or part of the 2017 Notes into shares of its common stock if the last reported sales price of the common stock over any 10 consecutive trading days equals or exceeds 150% of the applicable conversion price (a “Mandatory Conversion”). Each holder whose 2017 Notes are converted in a Mandatory Conversion will receive a make-whole payment for the converted notes in an amount equal to any unpaid interest that would have otherwise been payable on such 2017 Notes through the maturity date (a “Mandatory Conversion Make-Whole Payment”). Subject to certain limitations, the Company may pay any Mandatory Conversion Make-Whole Payments either in cash or in shares of common stock, at its election. The Company did not require any holders to convert in 2014, 2015 or 2016.

If a fundamental change of the Company occurs, the holders of 2017 Notes may require the Company to repurchase all or a portion of the 2017 Notes at a cash repurchase price equal to 100% of the principal amount of such 2017 Notes, plus accrued and unpaid interest, if any, through, but excluding, the repurchase date, plus a cash make-whole payment for the repurchased 2017 Notes in an amount equal to any unpaid interest that would otherwise have been payable on such convertible 2017 Notes through the maturity date. A fundamental change includes, among other things, the Company’s common stock ceasing to be listed on a national securities exchange. See Note 19 Subsequent Events for information on the Company’s listing status.

On July 31, 2014, January 28, 2015, May 13, 2015, November 12, 2015, December 7, 2015, March 28, 2016 and September 7, 2016, we entered into amendments to the 2017 Notes Indenture to, among other things, permit the offering and issuance of additional warrants and the incurrence of indebtedness by us under such additional warrants. In connection with the November 12, 2015 amendments, we did not issue any warrants or incur any indebtedness.

On June 1, 2015, the Company entered into further amendments to the 2017 Notes Indenture to, among other things, permit (i) the execution, delivery, and performance of the FCStone Agreements (as defined below) and the related Guaranty (as defined below), (ii) the incurrence of indebtedness by the Company and Agri-Energy pursuant thereto and (iii) the making of the investments by the Company and Agri-Energy thereunder.

On August 22, 2015, the Company entered into further amendments to the 2017 Notes Indenture to, among other things, permit (i) the execution, delivery, and performance of the License Agreement (as defined below) and (ii) the exchange of all or any portion of the 2022 Notes for common stock issued by the Company.

In connection with the transactions described above, the Company also entered into a Registration Rights Agreement, dated May 9, 2014 (the “Registration Rights Agreement”), pursuant to which the Company filed a registration statement on Form S-3 registering the resale of approximately 60,000 shares of the Company’s common stock which are issuable under the 2017 Notes. This registration statement was declared effective on July 25, 2014.

The Company has elected the fair value option for accounting of the 2017 Notes in order for management to mitigate income statement volatility caused by measurement basis differences between the embedded instruments or to eliminate complexities of applying certain accounting models. Accordingly, the principal amount of 2017 Notes outstanding at December 31, 2016 of $26.1 million has been recorded at its estimated fair value of $25.8 million and is included in the 2017 Notes recorded at fair value on the consolidated balance sheets at December 31, 2016. Debt issuance costs of $1.5 million were expensed at issuance and a gain of $4.2 million has been recognized in subsequent periods in connection with the election of the fair value option. Change in the estimated fair value of the 2017 Notes represents an unrealized gain included in gain (loss) from change in fair value of 2017 Notes in the consolidated statements of operations. The fair value of the 2017 Notes at the issuance date were equal to the net proceeds from the loan. During the twelve months ended December 31, 2016, the Company incurred cash interest expense of $2.6 million related to the 2017 Notes.

The following table sets forth the inputs to the lattice model that were used to value the 2017 Notes for which the fair value option was elected.

	December 31,
	2016			2015
Stock price	$	3.40		$	12.40
Conversion Rate per $1,000		2.90			2.90
Conversion Price	$	344.83		$	344.83

Estimated credit spread		20.0	%		30.0	%

The 2017 Notes were valued as of December 31, 2016, and used assumptions that existed at that time. The impact of our 2017 Notes Extension Transaction with the 2017 Notes holders (see Note 19 Subsequent Events) on certain key features, including extension of the maturity date to June 23, 2017 was not included in the assumptions used to value the 2017 Notes.

The following table sets forth information pertaining to the 2017 Notes which is included in the Company’s consolidated balance sheets (in thousands).

	Principal Amount of 2017 Notes		Change in Estimated Fair Value			Total
Balance - December 31, 2015	$	26,108	$	(4,543	)	$	21,565
Loss from change in fair value of debt		-	$	4,204			4,204
Balance - December 31, 2016	$	26,108	$	(339	)		25,769

Changes in certain inputs into the lattice model can have a significant impact on changes in the estimated fair value of the 2017 Notes. For example, the estimated fair value will generally decrease with: (1) a decline in the stock price; (2) decreases in the estimated stock volatility; and (3) a decrease in the estimated credit spread. The change in the estimated fair value of the 2017 Notes during the year ended December 31, 2016, represents an unrealized loss which has been recorded as a loss from change in fair value of 2017 Notes in the consolidated statements of operations.

Secured Debt

On September 30, 2016, Agri-Energy voluntarily paid off in full all outstanding amounts owed under the Amended Agri-Energy Loan Agreement and all material commitments and obligations under the Loan and Security Agreement and associated documents were terminated. As a result, at September 30, 2016, the Amended Agri-Energy Loan Agreement had a principal balance of zero. In connection with the repayment, TriplePoint Capital LLC (“TriplePoint”) terminated all of its security interests under the Amended Agri-Energy Loan Agreement (including any mortgages and membership interest pledges). In addition, the guaranties by the Company and Gevo Development of the obligations under the Amended Agri-Energy Agreement were also terminated.

The following table sets forth information pertaining to the Company’s secured debt issued to TriplePoint which is included in the Company’s consolidated balance sheets (in thousands).

Debt discounts associated with the issuance of the Company’s secured debt and convertible notes are recorded on the consolidated balance sheets as a reduction to related debt balances. The Company amortizes debt discount to interest expense over the term of the debt or expected life of the debt using the effective interest method. The unamortized debt discount at December 31, 2015 comprised a $17.0 current portion and $2.0 long-term portion. Unamortized debt issue costs totaled $2.0 (see Note 2 for more information).

Amended Agri-Energy Loan Agreement. In October 2011, the Original Agri-Energy Loan Agreement was amended and restated (the “Amended Agri-Energy Loan Agreement”) to provide Agri-Energy with additional term loan facilities of up to $15.0 million to pay a portion of the costs, expenses, and other amounts associated with the retrofit of the Agri-Energy Facility to produce isobutanol. In October 2011, Agri-Energy borrowed $10.0 million under the additional term loan facilities which originally matured in October 2015. In January 2012, Agri-Energy borrowed an additional $5.0 million under the additional term loan facilities which originally matured December 2015, bringing the total borrowed under the additional term loan facilities to $15.0 million.

May 2014 Amendments. In May 2014, the Company and its subsidiaries entered into a Consent Under and Third Amendment to Amended and Restated Plain English Growth Capital Loan and Security Agreement and Omnibus Amendment to Loan Documents (the “2014 Amendment”) pursuant to which TriplePoint amended its agreements with the Company and its subsidiaries and consented to (a) the execution, delivery, and performance of the Loan Agreement, the Exchange and Purchase Agreement, the Registration Rights Agreement, the 2017 Notes Indenture, the 2017 Notes, and the other documents related thereto (collectively the “Senior Loan Documents”); (b) the incurrence of the Term Loan with Whitebox and any other indebtedness under the Senior Loan Documents (collectively, the “Senior Indebtedness”); (c) the consummation of the exchange of the Term Loan for the 2017 Notes; (d) the offering, issuance and sale of the 2017 Notes to Whitebox and the conversion of any 2017 Notes into the common stock of the Company pursuant to the terms of the 2017 Notes Indenture; (e) the guaranty of the Senior Indebtedness provided by the Guarantors; (f) the liens granted by each of the Company and the Guarantors to secure the Senior Indebtedness and the other obligations under the Senior Loan Documents; (g) the consummation of any transactions contemplated by, and the terms of, the Senior Loan Documents by the Company and the Guarantors; and (h) the payment and performance of any of the obligations under the Senior Loan Documents by the Company and the Guarantors, including the making of dividends and distributions by the Guarantors to the Company for the purpose of enabling the Company to make any payments under the Senior Loan Documents.

As part of the 2014 Amendment, the Company repaid $9.8 million in principal payments due under the foregoing loan agreements with TriplePoint and entered into an amended loan agreement with TriplePoint. At such time, debt issuance costs were written off. At December 31, 2014, the amended loan agreement had a principal balance of $0.8 million, which amortizes over 36 months and bears interest at a rate equal to 9% per annum and matures in May 2017. There were no additional concessions or terms of the agreement which would require recognition of a gain or loss due to this amended agreement. Prior to the pay off of all outstanding amounts, Agri-Energy had granted TriplePoint a junior security interest in all of its assets as security for its obligations under the Amended Agri-Energy Loan Agreement.

On July 31, 2014, January 28, 2015, May 13, 2015, November 11, 2015, December 7, 2015, March 28, 2016 and September 7, 2016, we entered into further amendments to the Amended Agri-Energy Loan Agreement and the Gevo Security Agreement to, among other things, permit the offering and issuance of additional warrants and the incurrence of indebtedness by us under such additional warrants. In connection with the November 11, 2015 amendments, we did not issue any warrants or incur any indebtedness.

2022 Notes

The following table sets forth information pertaining to the 2022 Notes which is included in the Company’s consolidated balance sheets (in thousands). Refer to Note 19 Subsequent Events, for additional information.

	Principal Amount of 2022 Notes			Debt Discount			Debt Issue Costs			Total
Balance - December 31, 2015	$	22,400		$	(7,764	)	$	(295	)	$	14,341

Balance - December 31, 2016	$	9,575		$	(1,307	)	$	(47	)	$	8,221

In July 2012, the Company sold $45.0 million in aggregate principal amount of 2022 Notes, with net proceeds of $40.9 million, after accounting for $2.7 million and $1.4 million of discounts and issue costs, respectively. The 2022 Notes bear interest at 7.5% which is to be paid semi-annually in arrears on January 1 and July 1 of each year. The 2022 Notes will mature in July 2022, unless earlier repurchased, redeemed or converted. During the years ended December 31, 2016, 2015, and 2014, the Company recorded $4.0 million, $3.7 million, and $2.8 million , respectively, of non-cash interest expense related to the amortization of debt discounts and issue costs and recorded $1.2 million, $1.8 million and $2.0 million, respectively, of cash interest expense related to the 2022 Notes. The amortization of debt issue costs and debt discounts and cash interest are included as a component of interest expense in the consolidated statements of operations. The Company amortizes debt discounts and debt issue costs associated with the 2022 Notes using an effective interest rate of 40% from the issuance date through July 2017, a five-year period, which represents the date the holders can require the Company to repurchase the 2022 Notes.

The 2022 Notes are convertible at an initial conversion rate of 0.5856 shares of the Company’s common stock per $1,000 principal amount of 2022 Notes, subject to adjustment in certain circumstances as described in the Indenture. This is equivalent to an initial conversion price of approximately $1,707.65 per share of common stock. Holders may convert the 2022 Notes at any time prior to the close of business on the third business day immediately preceding the maturity date of July 1, 2022.

If a holder elects to convert its 2022 Notes prior to July 1, 2017, such holder shall be entitled to receive, in addition to the consideration upon conversion, a Coupon Make-Whole Payment. The Coupon Make-Whole Payment is equal to the sum of the present values of the number of semi-annual interest payments that would have been payable on the 2022 Notes that a holder has elected to convert from the last day through which interest was paid up to but excluding July 1, 2017, computed using a discount rate of 2%. The Company may pay any Coupon Make-Whole Payment either in cash or in shares of common stock at its election. If the Company elects to pay in common stock, the stock will be valued at 90% of the average of the daily volume weighted average prices of the Company’s common stock for the 10 trading days preceding the date of conversion. In November 2015, we issued 55,392 shares of common stock to redeem 2,500 bonds at a face value of $1,000 per bond and reduce the liability of the 2022 Notes by $2.5 million. The net loss on the extinguishment of the 2022 Notes was $0.05 million. In February 2015, we issued 8,502 shares of common stock to convert 2,000 bonds at a face value of $1,000 per bond to reduce the liability of the 2022 Notes by $2.0 million. The net gain on the extinguishment of the 2022 Notes was $0.3 million. In September 2016, the Company issued 699,968 shares of common stock in exchange for the redemption of $11.4 million of the 2022 Notes. The net loss on the extinguishment of the 2022 Notes was $0.9 million. In December 2016, the Company issued 251,832 shares of common stock in exchange for the redemption of $1.4 million of the 2022 Notes. The net gain on the extinguishment of the 2022 Notes was $0.1 million.

If a Make-Whole Fundamental Change (as defined in the Indenture) occurs and a holder elects to convert its 2022 Notes prior to July 1, 2017, the applicable conversion rate will increase based upon reference to the table set forth in Schedule A of the Indenture. In no event will the conversion rate increase to more than 0.6734 per $1,000 principal amount of 2022 Notes.

The Company shall have a provisional redemption right (“Provisional Redemption”) to redeem, at its option, all or any part of the 2022 Notes at a price payable in cash, beginning on July 1, 2015 and prior to July 1, 2017, provided that the Company’s common stock for 20 or more trading days in a period of 30 consecutive trading days ending on the trading day immediately prior to the date of the redemption notice exceeds 150% of the conversion price in effect on such trading day. On or after July 1, 2017, the Company shall have an optional redemption right (“Optional Redemption”) to redeem, at its option, all or any part of the 2022 Notes at a price payable in cash. The price payable in cash for the Optional Redemption or Provisional Redemption is equal to 100% of the principal amount of 2022 Notes redeemed plus any accrued and unpaid interest thereon through, but excluding, the repurchase date.

If there is an Event of Default (as defined in the Indenture) under the 2022 Notes, the holders of not less than 25% in principal amount of Outstanding Notes (as defined in the Indenture) by notice to the Company and the trustee may, and the trustee at the request of such holders shall, declare the principal amount of all the Outstanding Notes and accrued and unpaid interest thereon to be due and payable immediately. There have been no events of default as of December 31, 2016.
