Notes to Unaudited Consolidated Financial Statements

1. Nature of Business, Financial Condition and Basis of Presentation

Nature of Business . Gevo, Inc. (“Gevo” or the “Company,” which, unless otherwise indicated, refers to Gevo, Inc. and its subsidiaries) is a renewable chemicals and next generation biofuels company focused on the development and commercialization of alternatives to petroleum-based products with an emphasis on the production and sale of isobutanol and related products derived from renewable feedstocks. Gevo was incorporated in Delaware on June 9, 2005.

Gevo formed Gevo Development, LLC (“Gevo Development”) in September 2009 to finance and develop biorefineries either through joint venture, licensing arrangements, tolling arrangements or direct acquisition (see Note 9). Gevo Development became a wholly owned subsidiary of the Company in September 2010. Gevo Development purchased Agri-Energy, LLC (“Agri-Energy”) in September 2010.

Through May 2012, Agri-Energy, a wholly owned subsidiary of Gevo Development, was engaged in the business of producing and selling ethanol and related products produced at its plant located in Luverne, Minnesota (the “Agri-Energy Facility”). The Company commenced the retrofit of the Agri-Energy Facility in 2011 and commenced initial startup operations for the production of isobutanol at this facility in May 2012. In September 2012, the Company made the strategic decision to pause isobutanol production at the Agri-Energy Facility to focus on optimizing specific parts of the process to further enhance isobutanol production rates.

In 2013, the Company modified the Agri-Energy Facility in order to increase the isobutanol production rate. In June 2013, the Company resumed the limited production of isobutanol at the Agri-Energy Facility, operating one fermenter and one Gevo Integrated Fermentation Technology™ (“GIFT™”) separation system in order to (i) verify that the modifications had significantly reduced the previously identified infections, (ii) demonstrate that its biocatalyst performs in the one million liter fermenters at the Agri-Energy Facility, and (iii) confirm GIFT™ efficacy at commercial scale at the Agri-Energy Facility. In August 2013, the Company expanded production capacity at the Agri-Energy Facility by adding a second fermenter and second GIFT™ system to further verify its results with a second configuration of equipment. In October 2013, the Company began commissioning the Agri-Energy Facility on corn mash to test isobutanol production run rates and to optimize biocatalyst production, fermentation separation and water management systems.

In March 2014, the Company decided to leverage the flexibility of its GIFT™ technology and further modify the Agri-Energy Facility to enable the simultaneous production of isobutanol and ethanol. In July 2014, the Company began more consistent co-production of isobutanol and ethanol at the Agri-Energy Facility, with one fermenter utilized for isobutanol production and three fermenters utilized for ethanol production.   In line with the Company’s strategy to maximize asset utilization and site cash flows, this configuration of the plant was designed to allow the Company to continue to optimize its isobutanol technology at a commercial scale, while taking advantage of potentially favorable ethanol contribution margins. Also with a view to maximizing site cash flows, over certain periods of time, the Company operated the plant for the sole production of ethanol across all four fermenters.  

In September 2015, the Company began deploying additional capital at the Agri-Energy Facility, primarily designed to decrease the cost of isobutanol production by insourcing parts of the process that had previously been done off-site by third parties. This required the cessation of isobutanol production while this equipment was being installed. In March 2016, the Company completed these capital projects and reestablished isobutanol production in one fermenter.

As of September 30, 2016, the Company’s business activities were focused on the following areas:  optimizing the co-production of isobutanol, ethanol and related products at the Agri-Energy Facility; research and development; business development; business and financial planning; and raising capital.  Ultimately, the Company believes that the attainment of profitable operations is dependent upon future events, including completion of its development activities resulting in commercial production and sales of isobutanol or isobutanol-derived products and/or technology, obtaining adequate financing to repay or refinance its debt and complete its development activities and build out further isobutanol production capacity, gaining market acceptance and demand for its products and services, and attracting and retaining qualified personnel.

The Company has primarily derived revenue from the sale of ethanol, distiller’s grains and other related products produced as part of the ethanol production process at the Agri-Energy Facility. The production of ethanol alone is not the Company’s intended business and its future strategy is expected to depend on its ability to produce and market isobutanol and products derived from isobutanol. The Company is only beginning to achieve more consistent production and revenue from the sale of isobutanol, therefore, the historical operating results of the Company may not be indicative of future operating results for Agri-Energy or Gevo.

GEVO, INC.
Notes to Unaudited Consolidated Financial Statements (Continued)

Financial Conditi on . For the nine months ended September 30, 2016 and 2015, the Company incurred a consolidated net loss of $34.9 million and $28.2 million, respectively, and had an accumulated deficit of $374.4 million at September 30, 2016.  The Company’s cash and cash e quivalents at September 30, 2016 totaled $31.1 million which will be used for the following: (i) operating activities of the Agri-Energy Facility; (ii) operating activities at the Company’s corporate headquarters in Colorado, including research and develop ment work; (iii) capital improvements primarily associated with the Agri-Energy Facility; (iv) costs associated with optimizing isobutanol production technology; (v) exploration of restructuring, strategic alternatives and new financings; and (vi) debt ser vice  and repayment obligations.

The Company expects to incur future net losses as it continues to fund the development and commercialization of its product candidates. To date, the Company has financed its operations primarily with proceeds from multiple sales of equity and debt securities, borrowings under debt facilities and product sales.  While existing working capital at September 30, 2016 was sufficient to meet the cash requirements to fund planned operations through December 31, 2016, it is not sufficient to satisfy all of the Company’s debt obligations expected to become due and payable in 2017.  These conditions raise substantial doubt about the Company’s ability to continue as a going concern. The Company’s inability to continue as a going concern may potentially affect its rights and obligations under its debt obligations and may lead to bankruptcy.    

The Company’s t ransition to profitability is dependent upon, among other things, raising additional capital, repaying or refinancing its debt, the successful development and commercialization of its products and product candidates, the achievement of a level of revenue adequate to support the Company’s existing cost st ructure and the repayment or restructuring of the Company’s debt obligations. The Company may never achieve profitability or generate positive cash flows, and unless and until it does, the Company will continue to need to raise additional capital. Management intends to fund future operations through additional private and/or public offerings of debt or equity securities.  In addition, the Company may seek additional capital through arrangements with strategic partners or from other sources, may seek to restructure its debt and will continue to address its cost structure. The Company intends to continue to explore various financing alternatives to improve its capital structure, including reducing debt and extending maturities.  These efforts may include investments from a strategic partner, new equity or debt financings or exchange offers with the Company’s existing debt holders (including exchanges of debt for debt or equity securities) and other transactions involving the Company’s outstanding debt securities.  Notwithstanding, there can be no assurance that the Company will be able to raise additional funds, or achieve or sustain profitability or positive cash flows from operations.

Although substantial doubts exist about the Company’s ability to continue as a going concern, the accompanying financial statements have been prepared assuming that the Company will continue as a going concern and do not include adjustments that might result from the outcome of this uncertainty. This basis of accounting contemplates the recovery of the Company’s assets and the satisfaction of liabilities in the normal course of business.   

Basis of Presentation. The unaudited consolidated financial statements of the Company (which include the accounts of its wholly-owned subsidiaries Gevo Development and Agri-Energy) have been prepared, without audit, pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all information and footnotes required by accounting principles generally accepted in the U.S. for complete financial statements. These statements reflect all normal and recurring adjustments which, in the opinion of management, are necessary to present fairly the financial position, results of operations and cash flows of the Company at September 30, 2016 and are not necessarily indicative of the results to be expected for the full year. These statements should be read in conjunction with the Company’s consolidated financial statements and notes thereto included under the heading “Financial Statements and Supplementary Data” in Part II, Item 8 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 (the “Annual Report”).  

Reverse Stock Split.   On April 15, 2015, the Board of Directors of the Company approved a reverse split of the Company’s common stock, par value $0.01, at a ratio of one-for-fifteen.   This reverse stock split became effective on April 20, 2015 and, unless otherwise indicated, all share amounts, per share data, share prices, exercise prices and conversion rates set forth in these notes and the accompanying consolidated financial statements have, where applicable, been adjusted retroactively to reflect this reverse stock split.

Recent Accounting Pronouncements.   In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Cu stomers (“ASU 2014 ‑09”). The objective of ASU 2014-09 is to outline a new, single comprehensive model to use in accounting for revenue arising from contracts with customers. The new revenue recognition model provides a five-step analysis for determining wh en and how revenue is recognized, depicting the transfer of promised goods or services to customers in an amount that reflects the consideration that is expected to be received in exchange for those goods or services. ASU 2014 ‑ 09 is effective for fiscal years and interim periods within those years beginning after December 15, 2016.  Early adoption is not permitted. On July 9, 2015, the FASB voted to delay the implementation of ASU 2014-09 by one year to December 15, 2017.  In A pril 2016, the FASB issued Accounting Standards Update No. 2016-10 Revenue from Contracts with Customers, Identifying Performance Obligations and Licensing (“ASU 2016-10”) which provides additional clarification regarding Identifying Performance Obligation s and Licensing .  The Company is currently evaluating the impact of adopting ASU 2014 ‑09 and ASU 2016-10.  

In August 2014, the FASB issued Accounting Standards Update No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (“ASU 2014-15”).  The objective of ASU 2014-15 is to provide guidance in GAAP about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures.  ASU 2015-15 requires a management evaluation about whether there are conditions or events, considered in the aggregate, that raise substantial doubt about an entity’s ability to continue as a going concern within one year after the date the financial statements are issued or available to be issued. In doing so, ASU 2014-15 should reduce diversity in the timing and content of footnote disclosures.  ASU 2014 ‑ 15 is effective for fiscal years and interim periods within those years beginning after December 15, 2016.  The Company is currently evaluating the impact of adopting ASU 2014-15.

In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory ("ASU 2015-11") which requires an entity to measure in scope inventory at the lower of cost and net realizable value. Subsequent measurement is unchanged for inventory measured using LIFO or the retail inventory method. The amendments do not apply to inventory that is measured using last-in, first-out (LIFO) or the retail inventory method. The amendments apply to all other inventory, which includes inventory that is measured using first-in, first-out (FIFO) or average cost. The amendments are effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The amendments should be applied prospectively with earlier application permitted as of the beginning of an interim or annual reporting period. The Company is currently in the process of evaluating the impact of adoption of ASU 2015-11 on its consolidated balance sheets.

In August 2016, the FASB issued Accounting Standards Update No. 2016-15, Statement of Cash Flows Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”) which clarifies cash flow statement classification of eight specific cash flow issues. The purpose of ASU 2016-15 is to provide clarification and consistency for classifying the eight specific cash flow issues because current GAAP either is unclear or does not include specific guidance.  The amendments in the update are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years.  The Company is currently in the process of evaluating the impact of adoption of ASU 2016-15 on its consolidated balance sheets.

Adoption of New Accounting Pronouncements .  In April 2015, the FASB issued Accounting Standards Update No. 2015-03   Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”) intended to simplify the presentation of debt issuance costs. These amendments require that debt issuance costs be presented as a direct deduction from the carrying amount of the related debt liabilities, consistent with the presentation of debt discounts. This will result in the elimination of debt issuance costs as an asset and will reduce the carrying value of the Company’s debt liabilities. This guidance is effective for annual reporting periods, and interim periods within those annual periods, beginning after December 15, 2015. The Company has adopted the guidance as of January 1, 2016. The adoption of this guidance had an immaterial impact on our financial position and has resulted in the following retrospective adjustments to our consolidated balance sheet at December 31, 2015 (in thousands):

2. Earnings per Share

Basic net loss per share is computed by dividing the net loss attributable to Gevo common stockholders for the period by the weighted-average number of common shares outstanding during the period. Diluted earnings (loss) per share (“EPS”) includes the dilutive effect of common stock equivalents and is computed using the weighted-average number of common stock and common stock equivalents outstanding during the reporting period. Diluted EPS for the nine months ended September 30, 2016 and 2015 excluded common stock equivalents because the effect of their inclusion would be anti-dilutive, or would decrease the reported loss per share.

The following table sets forth securities outstanding that could potentially dilute the calculation of diluted earnings per share.

3. Inventories

The following table sets forth the components of the Company’s inventory balances (in thousands).

4. Property, Plant and Equipment

The following table sets forth the Company’s property, plant and equipment by classification (in thousands).

Included in cost of goods sold is depreciation of $4.5 million and $4.3 million during the nine months ended September 30, 2016 and 2015, respectively.   

Included in operating expenses is depreciation of $0.6 million and $0.6 million during the nine months ended September 30, 2016 and 2015, respectively.   

5. Embedded Derivatives

Convertible 2022 Notes

In July 2012, the Company issued 7.5% convertible senior notes due July 2022 (the “2022 Notes”) which contain the following embedded derivatives: (i) rights to convert into shares of the Company’s common stock, including upon a Fundamental Change (as defined in the indenture governing the 2022 Notes (the “Indenture”)); and (ii) a Coupon Make-Whole Payment (as defined in the Indenture) in the event of a conversion by the holders of the 2022 Notes prior to July 1, 2017. Embedded derivatives are separated from the host contract, the 2022 Notes, and carried at fair value when: (a) the embedded derivative possesses economic characteristics that are not clearly and closely related to the economic characteristics of the host contract; and (b) a separate, stand-alone instrument with the same terms would qualify as a derivative instrument. The Company has concluded that the embedded derivatives within the 2022 Notes meet these criteria and, as such, must be valued separate and apart from the 2022 Notes as one embedded derivative and recorded at fair value each reporting period.

The Company used a binomial lattice model in order to estimate the fair value of the embedded derivative in the 2022 Notes. A binomial lattice model generates two probable outcomes, whether up or down, arising at each point in time, starting from the date of valuation until the maturity date. A lattice was initially used to determine if the 2022 Notes would be converted, called or held at each decision point. Within the lattice model, the following assumptions are made: (i) the 2022 Notes will be converted early if the conversion value is greater than the holding value; or (ii) the 2022 Notes will be called if the holding value is greater than both (a) the Redemption Price (as defined in the Indenture) and (b) the conversion value plus the Coupon Make-Whole Payment at the time. If the 2022 Notes are called, then the holders will maximize their value by finding the optimal decision between (1) redeeming at the Redemption Price and (2) converting the 2022 Notes.

Using this lattice model, the Company valued the embedded derivative using a “with-and-without method”, where the value of the 2022 Notes including the embedded derivative is defined as the “with”, and the value of the 2022 Notes excluding the embedded derivative is defined as the “without”. This method estimates the value of the embedded derivative by looking at the difference in the values between the 2022 Notes with the embedded derivative and the value of the 2022 Notes without the embedded derivative. The lattice model requires the following inputs: (i) price of Gevo common stock; (ii) Conversion Rate (as defined in the Indenture); (iii) Conversion Price (as defined in the Indenture); (iv) maturity date; (v) risk-free interest rate; (vi) estimated stock volatility; and (vii) estimated credit spread for the Company.

GEVO, INC.
Notes to Unaudited Consolidated Financial Statements (Continued)

Inputs used to estimate the value of the embedded derivative as of December 31, 2015 determined the value of the embedded derivatives to be zero. Changes in certain inputs into the lattice model can have a significant impact on changes in the estimated fair value of the embedded derivatives. For example, the estimated fair value of the embedded derivatives will generally decrease with: (i) a decline in the stock price; (ii)  a decrease in the estimated stock volatility; and (iii) a decrease in the estimated credit spread.  During the period ended September 30, 2016, factors that could have a significant impact on the estimated fair value of the embedded derivatives indicate th e value to remain at zero.

Derivative Warrant Liability

In December 2013, the Company sold warrants to purchase 1,420,250 shares of the Company’s common stock (the “2013 Warrants”). In August 2014, the Company sold warrants to purchase 1,000,000 shares of the Company’s common stock (the “2014 Warrants”). In February 2015, the Company sold Series A warrants to purchase 2,216,667 shares of the Company’s common stock (the “Series A Warrants”) and Series B warrants to purchase 2,216,667 shares of the Company’s common stock (the “Series B Warrants”). In May 2015, the Company sold Series C warrants to purchase 430,000 shares of the Company’s common stock (the “Series C Warrants”).  In December 2015, the Company sold Series D warrants to purchase 10,050,000 shares of the Company’s common stock (the “Series D Warrants”) and Series E warrants to purchase 8,000,000 shares of the Company’s common stock (the “Series E Warrants”). In April 2016, the Company sold 10,292,858 Series F warrants to purchase one share of common stock (each a “Series F Warrant”) and 20,585,716 Series H warrants, each to purchase one share of common stock (each, a “Series H Warrant”), and 6,571,429 pre-funded Series G warrants (“Series G Warrants”) to purchase one share of common stock, pursuant to an underwritten public offering.  In September 2016, the Company sold 14,250,000 Series I warrants to purchase one share of common stock (each a “Series I Warrant”) and 3,700,000 pre-funded Series J warrants (“Series J Warrants”) to purchase one share of common stock, pursuant to an underwritten public offering.

The following table sets forth information pertaining to shares issued upon the exercise of such warrants as of September 30, 2016:

The agreements governing the above warrants include the following terms:

13

GEVO, INC.
Notes to Unaudited Consolidated Financial Statements (Continued)

Based on these terms, the Company has determined that the 2013 Warrants, the 2014 Warrants, the Series A Warrants, the Series C Warrants, the Series D Warrants, the Series F Warrants, the Series H Warrants and the Series I Warrants (together, the “Warrants”) qualify as derivatives and, as such, are presented as derivative warrant liability on the consolidated balance sheets and recorded at fair value each reporting period. The fair value of the Warrants was estimated to be $10.7 million and $10.5 million as of September 30, 2016 and December 31, 2015, respectively. The increase in the estimated fair value of the Warrants is the result of exercises of warrants during the period offset by the issuance of new warrants during the period.  

During the nine months ended September 30, 2016, the Company issued 51,151,312 shares of common stock as a result of the exercise of Series A, D, E, G, H and J Warrants.  The Company received proceeds of $10.9 million from such exercises. 

In May 2016, as permitted by Section 2(a) of the Series H Warrant agreement, the board of directors of the Company approved a voluntary reduction of the exercise price for 7.5 million of the outstanding Series H Warrants, from an exercise price of $0.75 per share of common stock to $0.30 per share of common stock, for the remaining term of these warrants. Except for the reduction in exercise price, the terms of these Series H Warrants remain unchanged.

In June 2016, as permitted by Section 2(a) of the Series H Warrant agreement, the Board of Directors of the Company approved a voluntary reduction of the exercise price for 3.0 million of the outstanding Series H Warrants, from an exercise price of $0.75 per share of common stock to $0.42 per share of common stock, for the remaining term of these warrants. The board of directors of the Company also approved a voluntary reduction of the exercise price for 2.0 million of the outstanding Series H Warrants, from an exercise price of $0.75 per share of common stock to $0.52 per share of common stock, for the remaining term of these warrants. Ultimately, the Company adjusted the exercise price to $0.52 per share of common stock for only 1.0 million of the Series H Warrants. Except for the reduction in exercise price, the terms of these Series H Warrants remain unchanged.

In June 2016, as permitted by Section 9 of the Series D Warrant agreement, the Company agreed with certain holders of the Series D Warrants to the amend the exercise price and accelerate the initial exercise date for 4,167,391 of the outstanding Series D Warrants held by such holders. Pursuant to that amendment, with respect to 4,167,391 of the outstanding Series D Warrants held by those holders, the exercise price was increased from an exercise price of $0.10 per share of common stock to $0.175 per share of common stock, for the remaining term of these warrants and the initial exercise date was changed from June 11, 2016 to June 8, 2016. Except for the change in exercise price and the initial exercise date, the terms of these Series D Warrants remained unchanged.

As of September 30, 2016, all of the Series H Warrants and Series D Warrants for which the exercise price had been adjusted were fully exercised.

6. Accounts Payable and Accrued Liabilities

The following table sets forth the components of the Company’s accounts payable and accrued liabilities in the consolidated balance sheets (in thousands).

7. Senior Secured Debt, Secured Debt and 2022 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 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 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 $25.9 million, the aggregate outstanding principal amount of the Term Loan provided in the First Advance for 10% convertible senior secured notes due 2017 (the “2017 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 will mature on March 15, 2017. The 2017 Notes have a conversion price (the “Conversion Price”) equal to $17.38 per share, or 0.0576 shares per $1 principal amount of 2017 Notes. Optional prepayment of the 2017 Notes is not permitted. The 2017 Notes bear interest at a rate equal to 10% per annum, which is payable 5% in cash and, under certain circumstances, 5% 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 aggregate outstanding principal amount, to be adjusted on an annual basis. As of September 30, 2016, there was a balance of $2.6 million in the interest reserve account. This amount is classified as restricted deposits.

GEVO, INC.
Notes to Unaudited Consolidated Financial Statements (Continued)

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 al lowing 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. 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 are guaranteed by Agri-Energy and Gevo Development (together, the “Guarantors”). On June 6, 2014, in connection with the issuance of the 2017 Notes, the Company and the Guarantors 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 Guarantors, including intellectual property and real property.  Agri-Energy has also entered into a mortgage with respect to the real property l ocated 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 the Conversion Rate of 0.0576 shares of common stock per $1.00 principal amount of the 2017 Notes (equivalent to the Conversion Price of approximately $17.38 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 2015 and has not required any holders to convert through the nine months ended September 30, 2016.

If a fundamental change of the Company occurs, the holders of the 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.

On July 31, 2014, January 28, 2015, May 13, 2015, November 12, 2015, December 7, 2015 March 28, 2016 and September 7, 2016, the Company 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 the Company under such additional warrants. In connection with the November 12, 2015 amendments, the Company did not issue any warrants or incur any indebtedness.

In connection with the transactions described above, the Company also entere d 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 1.2 million shares of the Company’s common sto ck which are issuable under the 2017 Notes. This registration statement was declared effective by the SEC on July 25, 2014.

The Company has elected the fair value option for accounting for the 2017 Notes in order for management to mitigate income statement volatility caused by measurement basis differences between the embedded instruments and to eliminate complexities of applying certain accounting models. Accordingly, the principal amount of 2017 Notes outstanding at September 30, 2016 of $26.1 million has been recorded at its estimated fair value of $25.2 million and is included in the 2017 Notes recorded at fair value on the consolidated balance sheets at September 30, 2016. Debt issuance costs of $1.5 million were expensed at issuance and a gain of $3.6 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 was equal to the net proceeds from the loan.  During the nine months ended September 30, 2016, the Company incurred cash interest expense of $3.2 million.

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.  

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

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 nine months ended September 30, 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.

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 on July 1, 2022, unless earlier repurchased, redeemed or converted. During the nine months ended September 30, 2016 and 2015, respectively, the Company recorded $2.2 million and $1.7 million of expense related to the amortization of debt discounts and issue costs; zero   and $1.0 million of expense related to th e conversion of debt; and $0.8 million and $0.9 million of interest expense related to the 2022 Notes. The amortization of debt issue costs, 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 1, 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 a conversion rate of 11.7113 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 a conversion price of approximately $85.35 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 September 2016, the Company issued 13,999,354 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 November 2015, the Company issued 1,107,833 shares of common stock in exchange for the redemption of $2.5 million of the 2022 Notes.     The net loss on the extinguishment of the 2022 Notes was $0.05 million.

In February 2015, the Company issued 170,042 shares of common stock to convert $2.0 million of the 2022 Notes. The net gain on the extinguishment of the 2022 Notes was $0.3 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 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 13.4680 shares of common stock per $1,000 principal amount of 2022 Notes.

If a Fundamental Change (as defined in the Indenture) occurs at any time, then each holder will have the right to require the Company to repurchase all of such holder’s 2022 Notes, or any portion thereof that is an integral multiple of $1,000 principal amount, for cash at a repurchase price of 100% of the principal amount of such 2022 Notes plus any accrued and unpaid interest thereon through, but excluding, the repurchase date.  Additionally, on July 1, 2017, each holder will have the right to require the Company to repurchase all of such holder’s 2022 Notes, or any portion thereof that is an integral multiple of $1,000 principal amount, for cash at a repurchase price of 100% of the principal amount of such 2022 Notes plus any accrued and unpaid interest thereon through, but excluding, the repurchase date.  A Fundamental Change includes, among other things, the Company’s common stock ceasing to be listed on a national securities exchange.

The Company has 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 for the 2022 Notes 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.

Pursuant to t he terms of the License Agreement, each party received a non-exclusive license under certain patents and patent applications owned or licensed (and sublicensable) by the other party for the production and use of biocatalysts in the manufacture of isobutano l using certain production process technology for the separation of isobutanol, and to manufacture and sell such isobutanol in any fields relating to the production or use of isobutanol and isobutanol derivatives, subject to the customer-facing field restr ictions described below.  Each party also received a non-exclusive license to perform research and development on biocatalysts for the production, recovery and use of isobutanol.

Each party may produce and sell up to 30 million gallons of isobutanol per year in any field on a royalty-free basis.  Butamax will be the primary customer-facing seller of isobutanol in the field of fuel blending (subject to certain exceptions, the “Direct Fuel Blending” field) and the Company will be the primary customer-facing seller of isobutanol in the field of jet fuel for use in aviation gas turbines (the “Jet” field, also subject to certain exceptions).  As such, subject to each party’s right to sell up to 30 million gallons of isobutanol per year in any field on a royalty-free basis, the Company will only sell isobutanol through Butamax in the Direct Fuel Blending field subject to a royalty based on the net sales price for each gallon of isobutanol sold or transferred by the Company, its affiliates or sublicensees within the Direct Fuel Blending field (whether through Butamax or not) and on commercially reasonable terms to be negotiated between the parties, and Butamax will only sell isobutanol through the Company in the Jet field subject to a royalty based on the net sales price for each gallon of isobutanol sold or transferred by Butamax, its affiliates or sublicensees within the Jet field (whether through the Company or not) and on commercially reasonable terms to be negotiated between the parties; provided, that each party may sell up to fifteen million gallons of isobutanol in a given year directly to customers in the other party’s customer-facing field on a royalty-free basis so long as the isobutanol volumes are within the permitted 30 million gallons of isobutanol sold or otherwise transferred per year in any field described above and, in certain instances, each party may then sell up to the total permitted 30 million gallons per year in the other party’s customer-facing field on a royalty-free basis. In addition, in order to maintain its status as the primary customer-facing seller in these specific fields, each party must meet certain milestones within the first five years of the License Agreement.  If such milestones are not met as determined by an arbitration panel, then the other party will have the right to sell directly to customers in the other party’s customer-facing field subject to the payment of certain royalties to the other party on such sales.

In addition to the royalties discussed above for sales of isobutanol in the Direct Fuel Blending field, and subject to the Company’s right to sell up to 30 million gallons of isobutanol per year in any field on a royalty-free basis, the Company will pay to Butamax a royalty per gallon of isobutanol sold or transferred by the Company, its affiliates or sublicensees within the field of isobutylene (a derivative of isobutanol) applications (other than isobutylene for paraxylene, isooctane, Jet, diesel and oligomerized isobutylene applications).  Likewise, in addition to the royalties discussed above for sales of isobutanol in the Jet field, and subject to Butamax’s right to sell up to 30 million gallons of isobutanol per year in any field on a royalty-free basis, Butamax will pay to the Company a royalty per gallon of isobutanol sold or transferred by Butamax, its affiliates or sublicensees within the fields of marine gasoline, retail packaged fuels and paraxylene (except for gasoline blending that results in use in marine or other fuel applications).  The royalties described above will be due only once for any volume of isobutanol sold or transferred under the License Agreement, and such royalties accrue when such volume of isobutanol is distributed for end use in the particular royalty-bearing field.  All sales of isobutanol in other fields will be royalty-free, subject to the potential technology fee described below.

In the event that the Company, its affiliates or sublicensees choose to employ a certain solids separation technology for the production of isobutanol at one of their respective plants, the Company is granted an option to license such technology from Butamax on a non-exclusive basis subject to the payment of a one-time technology license fee based on the rated isobutanol capacity for each such plant (subject to additional fees upon expansion of such capacity).  The Company also received the option to obtain an engineering package from Butamax to implement this solids separation technology on commercially reasonable terms to be negotiated between the parties and subject to the technology fee described above and an additional technology licensing fee for use of the solids separation technology applicable to ethanol capacity as provided in such engineering package from Butamax (which capacity is not duplicative of the rated isobutanol capacity referenced above) in instances where Butamax provides an engineering package for use at a particular plant that will run isobutanol and ethanol production side-by-side using the licensed solids separation technology at such plant.

The License Agreement encompasses both parties’ patents for producing isobutanol, including biocatalysts and separation technologies, as well as for producing hydrocarbon products derived from isobutanol, including certain improvements and new patent applications filed within seven years of the date of the License Agreement.  While the parties have cross-licensed their patents for making and using isobutanol, the parties will not share their own proprietary biocatalysts with each other.  The parties may use third parties to manufacture biocatalysts on their behalf and may license their respective technology packages for the production of isobutanol to third parties, subject to certain restrictions.  A third party licensee would be granted a sub-license, and would be subject to terms and conditions that are consistent with those under the License Agreement.

(“Toray Industries”). Working directly with Toray Industries, the Company employed prototypes of commercial operations from the petrochemical and refining industries to make para-xylene from isobutanol. Toray Industries used the Company’s bio-para-xylene (“bio-PX”) and commercially available renewable mono ethylene glycol to produce fully renewable PET films and fibers. In June 2012, the Company entered into a definitive agreement with Toray Industries, as amended in October 2013, for the joint development of an integrated supply chain for the production of bio-PET. Pursuant to the terms of the agreement with Toray Industries, the Company received $1.0 million which was used by the Company for the design and construction of a demonstration plant. In May 2014, the Company successfully shipped the requisite volumes of bio-PX associated with its contract with Toray Industries and, as a result, the Company recognized the $1.0 million, as well as revenue associated with the sale of the bio-PX, as a component of hydrocarbon revenue in the second quarter of 2014.

In June 2015, Agri-Energy entered into a Price Risk Management, Origination and Merchandising Agreement (the “Origination Agreement”) with FCStone Merchant Services, LLC (“FCStone”) and a Grain Bin Lease Agreement with FCStone (the “Lease Agreement” and, together with the Origination Agreement, the “FCStone Agreements”). Pursuant to the Origination Agreement, FCStone will originate and sell to Agri-Energy, and Agri-Energy will purchase from FCStone, the entire volume of corn grain used at the Agri-Energy Facility.  The initial term of the Origination Agreement will continue for a period of eighteen months and will automatically renew for additional terms of one year unless Agri-Energy gives notice of non-renewal to FCStone. FCStone will receive an origination fee for purchasing and supplying Agri-Energy with all of the corn used at the Agri-Energy Facility. As security for the payment and performance of all indebtedness, liabilities and obligations of Agri-Energy to FCStone, Agri-Energy granted to FCStone a security interest in the corn grain stored in grain storage bins owned and operated by Agri-Energy (“Storage Bins”) and leased to FCStone pursuant to the Lease Agreement. Pursuant to the Lease Agreement, FCStone will lease Storage Bins from Agri-Energy to store the corn grain prior to title of the corn grain transferring to Agri-Energy upon Agri-Energy’s purchase of the corn grain. FCStone agreed to lease Storage Bins sufficient to store 700,000 bushels of corn grain and pay to Agri-Energy $175,000 per year. The term of the Lease Agreement will run concurrently with the Origination Agreement, and will be extended, terminated, or expire in accordance with the Origination Agreement. The Company also entered into an unsecured guaranty (the “Guaranty”) in favor of FCStone whereby the Company guaranteed the obligations of Agri-Energy to FCStone under the Origination Agreement. The Guaranty shall terminate on the earlier to occur of (i) April 15, 2020 or (ii) termination of the Origination Agreement.

12. Fair Value Measurements

Accounting standards define fair value, outline a framework for measuring fair value, and detail the required disclosures about fair value measurements. Under these standards, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date in the principal or most advantageous market. Standards establish a hierarchy in determining the fair market value of an asset or liability. The fair value hierarchy has three levels of inputs, both observable and unobservable. Standards require the utilization of the highest possible level of input to determine fair value.

Level 1 – inputs include quoted market prices in an active market for identical assets or liabilities.

Level 2 – inputs are market data, other than Level 1, that are observable either directly or indirectly. Level 2 inputs include quoted market prices for similar assets or liabilities, quoted market prices in an inactive market, and other observable information that can be corroborated by market data.

Level 3 – inputs are unobservable and corroborated by little or no market data.

Inventories. The Company records its inventory, primarily corn inventory, at fair value only when the Company’s cost of corn purchased exceeds the market value for corn. The Company determines the market value of corn based upon Level 1 inputs using quoted market prices. The Company incurred a write-down of inventory of $0.1 million during the nine months ended September 30, 2015. The Company incurred no write-down of inventory during the nine months ended September 30, 2016.

Secured Debt . The Company has estimated the fair value of its secured debt obligations based upon discounted cash flows with Level 3 inputs, such as the terms that management believes would currently be available to the Company for similar issues of debt, taking into account the current credit risk of the Company and other market factors.  

2017 Notes.   The Company has estimated the fair value of the 2017 Notes to be $25.2 million and $21.6 million at September 30, 2016 and December 31, 2015, respectively, based upon Level 2 inputs, including the market price of the Company’s common stock.  The Company has valued the 2017 Notes and all of its components using the fair value option as there are no embedded instruments which qualify for equity presentation.  See Note 7 for the fair value inputs used to estimate the fair value of the 2017 Notes.

2022 Notes Embedded Derivative . The Company has estimated the fair value of the 2022 Notes, including the embedded derivative, to be $8.8 million and $14.3 million at September 30, 2016 and December 31, 2015, respectively, based upon Level 2 inputs, including the market price of the 2022 Notes derived from actual trades of the 2022 Notes. The Company has estimated the fair value of the embedded derivative on a stand-alone basis to be zero at September 30, 2016 and December 31, 2015, based upon Level 2 inputs. See Note 5 above for the fair value inputs used to estimate the fair value of the 2022 Notes with and without the embedded derivative and the fair value of the embedded derivative.
