Description of Business	Dec. 31, 2015
Accounting Policies [Abstract]
Description of Business	Note 1. Description of Business Organization Arcadia Biosciences, Inc. (the "Company"), was incorporated in the state of Arizona in 2002 and maintains its headquarters in Davis, California, with additional facilities in Seattle, Washington; Phoenix, Arizona; and American Falls, Idaho. The Company was reincorporated in Delaware in March 2015. The Company pursues agriculture-based biotechnology business opportunities that improve the environment and human health. The Company is an agricultural biotechnology trait company with an extensive and diversified portfolio of late-stage crop productivity and product quality traits addressing multiple crops that supply the global food and feed markets. Its traits are focused on high-value enhancements that increase crop yields by enabling plants to more efficiently manage environmental and nutrient stresses, and that enhance the quality and value of agricultural products. In February 2012, the Company formed Verdeca LLC ("Verdeca", see Note 7), which is jointly owned with Bioceres, Inc. ("Bioceres USA"), a U.S. wholly owned subsidiary of Bioceres, S.A. ("Bioceres"), an Argentine corporation. Bioceres is an agricultural investment and development cooperative. Verdeca was formed to develop and deregulate soybean varieties using both partners’ agricultural technologies. Reverse Stock Split In April 2015, the Company’s board of directors approved an amended and restated certificate of incorporation to effect a reverse split on the Company’s issued and outstanding common stock at a one-for-four ratio. In May 2015, the Company’s stockholders approved the certificate of amendment, which the Company filed on May 8, 2015 with the Secretary of State of Delaware to effect the reverse split. The par value and authorized shares of common stock and convertible preferred stock were not adjusted as a result of the reverse split. All issued and outstanding common stock, options to purchase common stock and per share amounts contained in the consolidated financial statement have been retroactively adjusted to reflect the reverse stock split for all periods presented. The consolidated financial statements have also been retroactively adjusted to reflect a proportional adjustment for the conversion ratio for each series of redeemable convertible preferred stock and convertible preferred stock. Initial Public Offering In May 2015, the Company completed an initial public offering (“IPO”) and subsequently in June 2015, the Company completed the sale of additional shares upon exercise of the underwriters’ over-allotment option. In connection with the IPO, the Company issued 8,528,306 shares of common stock at $8.00 per share, which raised $58.4 million in proceeds, net of underwriting discounts and commissions of $4.8 million and offering expenses of $5.0 million. At the closing of the IPO, all of the outstanding shares of convertible preferred stock and redeemable convertible preferred stock were automatically converted into 32,972,793 shares of common stock. Following the IPO, there were no shares of preferred stock outstanding. In connection with the IPO, the Company filed an Amended and Restated Certificate of Incorporation to change the authorized capital stock to 400,000,000 shares designated as common stock and 20,000,000 shares designated as preferred stock, all with a par value of $0.001 per share.

Summary of Significant Accounting Policies

Note 2. Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The consolidated financial statements include the accounts of the Company and Verdeca LLC. All intercompany balances and transactions have been eliminated in consolidation. The Company prepares its consolidated financial statements in conformity with accounting principles generally accepted in the United States of America, or U.S. GAAP (“GAAP”), and with the rules of the Securities and Exchange Commission. The Company uses a qualitative approach in assessing the consolidation requirement for variable interest entities ("VIEs"). This approach focuses on determining whether the Company has the power to direct the activities of the VIE that most significantly affect the VIE’s economic performance and whether the Company has the obligation to absorb losses, or the right to receive benefits, that could potentially be significant to the VIE. For all periods presented, the Company has determined that it is the primary beneficiary of Verdeca, which is a VIE. The Company evaluates its relationships with the VIEs upon the occurrence of certain significant events that affect the design, structure or other factors pertinent to the primary beneficiary determination.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions in the Company’s consolidated financial statements and notes thereto. Significant estimates and assumptions made by management included the determination of the provision for income taxes, costs to complete government grants and research contracts, reserves for inventory, and the development period of revenue-generating technologies. Management bases its estimates on historical experience and on various other market-specific and relevant assumptions that management believes to be reasonable under the circumstances. Actual results could differ from those estimates.

Cash and Cash Equivalents

The Company considers any liquid investments with a stated maturity of three months or less at the date of purchase to be cash equivalents. Cash and cash equivalents consist of cash on deposit with banks. The Company limits cash investments to financial institutions with high credit standings; therefore, management believes that there is no significant exposure to any credit risk in the Company’s cash and cash equivalents. However, as of December 31, 2015 and 2014, a substantial portion of the Company’s cash in depository accounts is in excess of the federal deposit insurance limits.

Investments in Equity and Debt Securities

The Company uses the equity method to account for investments in equity securities if the investment provides the Company the ability to exercise significant influence over operating and financial policies of the investee. The Company includes its proportionate share of earnings and/or losses of the equity method investee in its Consolidated Statements of Operations and Comprehensive Loss. The carrying value of the equity investments is reported using the equity method in the Consolidated Balance Sheets. As of December 31, 2015 and 2014, the Company’s investment in LCS is $0. See Note 6 – Investments in Unconsolidated Entity for additional information.

Investments in equity securities in which the Company holds less than 20% voting interest and on which the Company does not have the ability to exercise significant influence or account for under the equity method and do not have readily determinable fair values for are accounted for under the cost method. Cost method investments are originally recorded at cost and are reported on the Consolidated Balance Sheets.

Investments in debt securities are carried at fair value and classified as available-for-sale. Realized gains and losses on available-for-sale securities are included in other income (loss) — net in our Consolidated Statements of Operations and Comprehensive Loss. Unrealized gains and losses, net of deferred taxes, on available-for-sale securities are included in our Consolidated Balance Sheets as a component of accumulated other comprehensive income (loss) ("AOCI”). Securities classified as available-for-sale are reported as cash and cash equivalent, short-term investments or long-term investments in the Consolidated Balance Sheets based on the nature of the investments and maturity period. Short-term investments have maturities of less than a year and long-term investments have maturities of a year and greater from the balance sheet date. The Company’s debt securities are primarily comprised of U.S. government securities, U.S. government agency securities, commercial paper, certificates of deposit, and money markets. These available-for-sale investments are held in the custody of a major financial institution.

Other-than-Temporary Impairments on Investment

The Company regularly reviews each of its investments for impairment by determining if the investment has sustained an other-than-temporary decline in its value, in which case the investment is written down to its fair value by a charge to earnings. Factors that are considered by the Company in determining whether an other-than-temporary decline in value has occurred include (i) the market value of the investment in relation to its cost basis, (ii) the financial condition of the investment, and (iii) the Company’s intent and ability to retain the investment for a sufficient period of time to allow for recovery of the market value of the investment. As of December 31, 2015 and 2014, there was no impairment of the Company’s investments.

Accounts Receivable

Accounts receivable represents amounts owed to the Company from product sales, licenses and contract research and government grants. The carrying value of the Company’s receivables represents estimated net realizable values. The Company generally does not require collateral and estimates any required allowance for doubtful accounts based on historical collection trends, the age of outstanding receivables, and existing economic conditions. If events or changes in circumstances indicate that specific receivable balances may be impaired, further consideration is given to the collectability of those balances and the allowance is recorded accordingly. Past-due receivable balances are written off when the Company’s internal collection efforts have been unsuccessful in collecting the amounts due. The Company had no amounts reserved for doubtful accounts at December 31, 2015 and 2014 as the Company expected full collection of the accounts receivable balances as of each of these dates.

SONOVA® Gamma Linolenic Acid (“GLA”) Safflower Oil Inventory

Proprietary safflower plants are grown, producing seed with a high-GLA content. This seed is used for subsequent plantings or processed, and sold as GLA oil, including Sonova 400 GLA safflower oils and Sonova Ultra GLA safflower oil, which we refer to as our Sonova products. Amounts inventoried consist primarily of fees paid to contracted cooperators to grow the crops and costs to process and store harvested seed. Inventory costs are tracked on a lot-identified basis, valued at the lower of cost or market, and are included as cost of product revenues when sold. The Company provides for inventory reserves when conditions indicate that the selling price may be less than cost due to physical deterioration, obsolescence, changes in price levels, or other factors. Additionally, the Company provides reserves for excess and slow-moving inventory on hand that is not expected to be sold within a reasonable timeframe to reduce the carrying amount to its estimated net realizable value. The reserves are based upon estimates about future demand from the Company’s customers and distributors and market conditions. The Company had inventory reserves for excess and slow-moving inventory of $2.3 million and $1.7 million as of December 31, 2015 and 2014, respectively, relating to reserves recorded primarily as a result of changes in conditions of specific customers and regulatory delays for the use of its Sonova products by certain new industries.

The inventories—current line item in the balance sheet consists of the cost of oil inventory forecasted to be sold in the next 12 months, as of the balance sheet date. The inventories—noncurrent line item consists of oil and seed inventory expected to be used in production or sold beyond the next 12 months, as of the balance sheet date.

Raw materials inventories consist primarily of seed production costs incurred by our contracted cooperators. Finished goods inventories consist of GLA oil that is available for sale. Inventories consist of the following (in thousands):

	As of December 31,
	2015		2014
Raw Materials	$	665	$	1,004
Finished Goods		1,496		1,569
Inventories	$	2,161	$	2,573

Property and Equipment

Property and equipment acquisitions are recorded at cost. Provisions for depreciation are calculated using the straight-line method over the following average estimated useful lives of the assets:

	Years
Laboratory equipment	5
Software and computer equipment	3
Furniture and fixtures	7
Vehicles	5
Leasehold improvements	2-10	*

*	Leasehold improvements are depreciated over the shorter of the estimated life of the asset or the remaining life of the lease.

Impairment of Long-Lived Assets

The Company evaluates if events and circumstances have occurred that indicate the remaining estimated useful life of long-lived assets and identifiable intangible assets may warrant revision or that the remaining balance of these assets may not be recoverable. In evaluating for recoverability, the Company estimates the future undiscounted cash flows expected to result from the use of the assets and their eventual disposition. In the event that the balance of any asset exceeds the future undiscounted cash flow estimate, impairment is recognized based on the excess of the carrying amounts of the asset above its estimated fair value. As of December 31, 2015 and 2014, there was no impairment of the Company’s long-lived assets.

Fair Value of Financial Instruments

Fair value accounting is applied for all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the consolidated financial statements on a recurring basis (at least annually). Assets and liabilities recorded at fair value in the consolidated financial statements are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels, which are directly related to the amount of subjectivity, associated with the inputs to the valuation of these assets or liabilities are as follows:

Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company can access at the measurement date.

Level 2 inputs are observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 inputs are unobservable inputs for the asset or liability.

Concentration of Risk

Cash and cash equivalents are maintained with several financial institutions. Deposits held with banks may exceed the amount of insurance provided on such deposits. Generally, these deposits may be redeemed upon demand and are maintained with financial institutions with reputable credit and therefore bear minimal credit risk. The Company seeks to mitigate its credit risks by spreading such risks across multiple counterparties and monitoring the risk profiles of these counterparties.

Customer Concentration

Significant customers are those that represent greater than 10% of the Company’s total revenues or gross accounts receivable balance at each respective balance sheet date.

Customers representing greater than 10% of accounts receivable were as follows (in percentages):

	As of December 31,
	2015		2014
Customer A		32		94
Customer E		32		—
Customer F		25		—

Customers representing greater than 10% of total revenues were as follows (in percentages):

	For Year Ended December 31,
	2015		2014
Customer A		12		29
Customer D		22		36
Customer F		14		—
Customer G		13		—

Deferred Offering Costs

Deferred offering costs consisting of direct incremental legal, consulting, banking and accounting fees relating to the initial public offering completed in May 2015 ("IPO") of $9.8 million were capitalized and offset against the gross IPO proceeds of $68.2 million. The Company recorded $0 and $2.8 million of deferred offering costs in other noncurrent assets on the Consolidated Balance Sheets as of December 31, 2015 and December 31, 2014, respectively.

Stock-Based Compensation

The Company recognizes compensation expense related to employee stock purchase plan and the cost of stock-based compensation awards made to employees and directors on a straight-line basis over the requisite service period, net of estimated forfeitures. Judgment is required in estimating the amount of stock-based awards that will be forfeited prior to vesting. Compensation expense could be revised in subsequent periods if actual forfeitures differ from those estimates. The Company has selected the Black-Scholes option-pricing model and various inputs to estimate the fair value of its stock-based awards. See Note 11 for additional information.

The Company accounts for compensation expense related to stock options granted to non-employees based on the fair values estimated using the Black-Scholes model. Stock options granted to non-employees are re-measured at each reporting date until the award is vested.

Income Taxes

The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial reporting and the tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized.

Net Loss per Share

Basic net loss per share, which excludes dilution, is computed by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share reflects the potential dilution that could occur if securities or other contracts to issue common stock, such as stock options, convertible promissory notes, convertible preferred stock, redeemable convertible preferred stock and warrants, result in the issuance of common stock which share in the losses of the Company. Certain potential shares of common stock have been excluded from the computation of diluted net loss per share as their effect would be anti-dilutive. Such potentially dilutive shares are excluded when the effect would be to reduce the loss per share. The Company’s convertible preferred stock are considered to be participating securities as they are entitled to participate in undistributed earnings with shares of common stock. Due to net losses, there is no impact on earnings per share calculation in applying the two-class method since the participating securities have no legal requirement to share in any losses.

Revenue Recognition

Revenue is generated through product sales, license agreements, contract research agreements, and government grants. The Company recognizes revenue when the following criteria have been met: persuasive evidence of an arrangement with the customer exists; price and terms of the arrangement are fixed or determinable; delivery of the product has occurred or the service has been performed in accordance with the terms of the arrangement; and collectability is reasonably assured.

For revenue agreements with multiple-element arrangements, such as license and contract agreements, the Company analyzes the arrangements to determine whether the deliverables can be separated or whether they must be accounted for as a single unit of accounting. This determination is generally based on whether any deliverable has stand-alone value to the customer. This analysis also establishes a selling price hierarchy for determining how to allocate arrangement consideration to identified units of accounting. When deliverables are separable, consideration received is allocated to the separate units of accounting based on the relative selling price method and the appropriate revenue recognition principles are applied to each unit. The selling price used for each unit of accounting is based on estimated selling price as neither vendor-specific nor third-party evidence is available. When the Company determines that an arrangement should be accounted for as a single unit of accounting, it must determine the period over which the performance obligations will be performed and revenue will be recognized over the performance period.

Product Revenues

Product revenues consist of sales of our Sonova products. Product revenues are recognized once passage of title has occurred, contractually specified acceptance criteria have been met, and all other revenue recognition criteria have been met. Shipping and handling costs charged to customers are recorded as revenues and included in cost of product revenues at the time the sale is recognized.

License Revenues

The Company’s license agreements generally include up-front, nonrefundable license fees, annual license fees, and subsequent milestone payments. Upon commercialization of a product utilizing a licensed technology, the Company receives certain value-sharing payments associated with the incremental revenue attributable to the licensed technology.

The Company has determined that, at the inception of each license agreement, there is only one deliverable for the license for, access to, and assistance with the development of the specified intellectual property. The up-front nonrefundable license fees are recognized as revenue proportionally over the development period, which approximates the expected efforts by the Company. The development period is estimated based upon factors such as type of traits, nature of crops and geographies, which are used to establish the initial deferral period. The Company continually reviews such estimates based on progress toward product commercialization. If the deferral period estimate changes, the amount of revenue recognized during the period is adjusted to reflect the updated deferred balances as of the current period-end. The annual license fees are payable at the end of the annual period and such fees typically are not required to be paid if the agreement is cancelled prior to the due date. Therefore, annual license fees are only recognized when they become due.

The Company’s license agreements generally include contingent milestone payments in the development life cycle of the related technology, such as achievement of specific technological targets, successful results from field trials, filing for approval with regulatory agencies, approvals granted by regulatory agencies and commercial launch of a product utilizing the licensed technology. The Company evaluates whether each milestone is substantive and at risk at the time the agreement is executed. This evaluation includes an assessment of whether (a) the consideration is commensurate with either (i) the entity’s performance to achieve the milestone or (ii) the enhancement of the value of the delivered item(s) as a result of a specific outcome resulting from the entity’s performance to achieve the milestone; (b) the consideration relates solely to past performance; and (c) the consideration is reasonable relative to all of the deliverables and payment terms within the arrangement. The Company generally considers non-refundable milestones that the Company expects to be achieved as a result of the Company’s efforts during the period of the Company’s performance obligations under the license agreement to be substantive and recognizes them as revenue upon the achievement of the milestone, assuming all other revenue recognition criteria are met.

Once a product containing one or more of the Company’s traits is commercialized, the Company is entitled to receive a portion of the incremental revenue that the trait generates for its commercial partner. These value-sharing payments will be recorded on the accrual basis when results are reliably measurable, collectability is reasonably assured, and all other revenue recognition criteria are met. None have been received to date.

Contract Research Revenues

Contract research revenues consist of amounts earned from performing contracted research activities for third parties. Activities performed are related to breeding programs or the genetic engineering of plants and are subject to an executed agreement. Generally, fees for research and development activities are recognized as the services are performed over the performance period, as specified in the respective agreements, assuming all other revenue recognition criteria are met.

Similar to the license agreements, under the contract research agreements, once a product containing one or more of the Company’s traits is commercialized, the Company is entitled to receive a portion of the incremental revenue that the trait generates for its commercial partner. These value-sharing payments will be recorded on the accrual basis when results are reliably measurable, collectability is reasonably assured, and all other revenue recognition criteria are met.

Government Grant Revenues

Based on the terms of the government grant, the Company recognizes revenue from payments received from government entities for research and development activities over a contractually defined period. Revenues from government grants are recognized in the period during which the related costs are incurred, provided that the conditions under which the government grants were provided have been met.

Unearned Revenue

The Company defers revenue to the extent that cash received in conjunction with a license agreement, contract or grant exceeds the revenue recognized in accordance with Company policies.

Research and Development Expenses

Research and development expenses consist of costs incurred in the discovery, development, and testing of the Company’s product candidates. These expenses consist primarily of employee salaries and benefits, including stock-based compensation, fees paid to subcontracted research providers, fees associated with in-licensing technology, royalty agreements, land leased for field trials, chemicals and supplies and other external expenses. These costs are expensed as incurred. Additionally, as disclosed in Note 12, the Company is required from time to time to make certain milestone payments in connection with the development of technologies. These milestone payments are expensed at the time the milestone is achieved and deemed payable.

Accounting Changes And Error Corrections [Abstract]
Recent Accounting Pronouncements	Note 3. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. In August 2015, FASB issued ASU 2015-14, Revenue from Contracts with Customers, which defers the effective date by one year. The new standard will be effective for the Company on January 1, 2018, which is the effective date for public companies. Early application with an effective date of January 1, 2017 is permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 and ASU 2015-14 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting. In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, which provides guidance on determining when and how to disclose going-concern uncertainties in the consolidated financial statements. The new standard requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the consolidated financial statements are issued. An entity must provide certain disclosures if "conditions or events raise substantial doubt about the entity’s ability to continue as a going concern." The ASU applies to all entities and is effective for annual periods ending after December 15, 2016, and interim periods thereafter, with early adoption permitted. The Company does not anticipate a material change to its consolidated financial statements upon the adoption of this ASU. However, it will be required to evaluate and determine if further disclosure is necessary at each balance sheet date. In February 2015, the FASB issued ASU 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis. The amendments significantly change the consolidation analysis required under U.S. GAAP. Reporting entities will need to reevaluate all their previous consolidation conclusions. ASU 2015-02 will be effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. The Company does not anticipate that the adoption of this ASU will materially change the presentation of our consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs, which requires debt issuance costs to be presented in the balance sheet as a direct deduction from the associated debt liability. ASU 2015-03 will not change the amortization of debt issuance costs, which will continue to follow the existing accounting guidance. ASU 2015-03 will be effective for interim and annual reporting periods beginning after December 15, 2015. Early application is permitted. The reporting entity must retrospectively apply ASU 2015-03. The Company adopted ASU 2015-03 for the annual reporting period of December 31, 2015. Based on the Company’s analysis to assess the impact on prior periods in accordance with the retrospective application, debt issuance costs were immaterial thus no adjustments were made to the balance sheet classification. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory, which applies guidance on subsequent measurement of inventory. An entity should measure inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonable predictable costs of completion, disposal and transportation. The guidance excludes inventory measured using LIFO or the retail inventory method. ASU 2015-11 will be effective for interim and annual reporting periods beginning after December 15, 2016. Early application is permitted. The Company does not anticipate that the adoption of this ASU will materially change the presentation of its consolidated financial statements. In November 2015, the FASB issued ASU 2015-17, Income Taxes (Topic 740). Current GAAP requires an entity to separate deferred income tax liabilities and assets into current and noncurrent amounts in a classified statement of financial position. The amendment in this update requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. This standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016, with early adoption permitted. The Company had prospectively adopted ASU 2015-17 for the annual reporting period of December 31, 2015. In January 2016, the FASB issued ASU 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in this update impacts classification, additional fair value measurement, impairment assessment of equity investments and current required disclosures. This standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted if the entity meets certain early application guidance. The Company is currently evaluating the impact of the adoption of ASU 2016-01 on its operating results and financial position.

Investments and Fair Value Measurements

Note 5. Investments and Fair Value Measurements

Available-for-Sale Investments

The Company classified cash equivalents, short-term and long-term investments as “available-for-sale.” Investments are free of trading restrictions. The investments are carried at fair value, based on quoted market prices or other readily available market information. Unrealized gains and losses, net of taxes, are included in accumulated other comprehensive income (loss), which is reflected as a separate component of stockholder’s equity (deficit) in the Consolidated Balance Sheets. Gains and losses are recognized when realized in the Consolidated Statements of Operations and Comprehensive Loss. The Company did not have available-for-sale securities prior to the third quarter of 2015.

The Company’s investments in fixed income securities consisted of the following as of December 31, 2015:

(Dollars in thousands)	Amortized Cost		Unrealized Gains		Unrealized Losses			Estimated Fair Value

Total Assets at Fair Value	$	67,930	$	1	$	(116	)	$	67,815

The Company did not have any investment categories that were in a continuous unrealized loss position for more than twelve months as of December 31, 2015. The unrealized gains and losses amounts above are included in AOCI as of December 31, 2015. All long-term investments will mature in 2017.

As of December 31, 2015, for fixed income securities that were in unrealized loss positions, the Company has determined that (i) it does not have the intent to sell any of these investments, and (ii) it is not more likely than not that it will be required to sell any of these investments before recovery of the entire amortized cost basis. The Company anticipates that it will recover the entire amortized cost basis of such fixed income securities and has determined that no other-than-temporary impairments associated with credit losses were required to be recognized during the year ended December 31, 2015.

Fair Value Measurement

The fair value of the available-for-sale investments at December 31, 2015 were as follows:

The carrying values of the Company’s financial instruments, including cash equivalents, accounts receivable, and accounts payable, approximated their fair values due to the short period of time to maturity or repayment.

The carrying values of the Company’s promissory notes, convertible promissory notes, and notes payable approximate their fair values for the years ended December 31, 2015 and 2014 as the market rates currently available to the Company and other assumptions have not changed significantly. These were classified as Level 2.

The Company’s Level 3 liabilities, which were measured and recorded on a recurring basis, consist of derivative liabilities related to the convertible promissory note.

Limagrain Cereal Seeds LLC

The Company owns a 35% ownership position in Limagrain Cereal Seeds LLC (“LCS”). The remaining 65% of LCS is owned by Vilmorin & Cie (“Limagrain”), a major global producer and marketer of field crop and vegetable seeds, through its wholly owned subsidiary, Vilmorin USA (“VUSA”). LCS improves and develops new wheat and barley varieties utilizing genetic and breeding resources, as well as advanced technologies from Limagrain and the Company. Funding for LCS comes from an initial pro rata equity investment from each partner and with subsequent financing in the form of debt from VUSA. As of December 31, 2015, the debt balance was $19.0 million with a maturity date of April 15, 2016. While it is the Company’s expectation that VUSA will provide LCS with additional debt financing and extend maturity for payment as needed, should additional capital in the form of equity be necessary to support the operations of LCS, the Company has the option to fund its pro rata share of such cash or elect to have its ownership percentage diluted. As of December 31, 2015 and December 31, 2014, the Company’s investment in LCS has been reduced to $0 as a result of its equity method loss recognition.

Variable Interest Entity	12 Months Ended
Variable Interest Entity	Dec. 31, 2015
Equity Method Investments And Joint Ventures [Abstract]
Variable Interest Entity	Note 7. Variable Interest Entity In February 2012, the Company formed Verdeca LLC, which is jointly owned with Bioceres, Inc. ("Bioceres"), a U.S. wholly owned subsidiary of Bioceres, S.A., an Argentine corporation. Bioceres, S.A. is an agricultural investment and development company owned by approximately 250 shareholders, including some of South America’s largest soybean growers. Verdeca was formed to develop and deregulate soybean varieties using both partners’ agricultural technologies. Both the Company and Bioceres incur expenses in support of specific activities agreed, as defined by joint work plans, which apply fair market value to each partner’s activities. Unequal contributions of services are equalized by the partners through cash payments. Verdeca is not the primary obligor for these activities performed by the Company or Bioceres. An agreement executed in conjunction with the formation of Verdeca specified that if Bioceres determines it requires cash to fund its contributed services (subject to certain annual limits), Bioceres, S.A. may elect to sell shares of its common stock to the Company for an amount not exceeding $5.0 million in the aggregate over a four-year period. The Company determined that its commitment to purchase common stock in Bioceres, S.A. as a means to provide capital to Verdeca resulted in a de facto agency relationship between the Company and Bioceres. The Company considers qualitative factors in assessing the primary beneficiary which include understanding the purpose and design of the VIE, associated risks that the VIE creates, activities that could be directed by the Company, and the expected relative impact of those activities on the economic performance of the VIE. Based on an evaluation of these factors, the Company concluded that it is the primary beneficiary of Verdeca. As a result of the agreement to fund future contributions by Bioceres, Inc., the Company purchased common stock of Bioceres, S.A. in the aggregate amount of $2.0 million between January 2013 and August 2014. The Company’s maximum commitment to purchase stock in Bioceres, S.A. under the original funding agreement amounted to $2.0 million for 2014 and $1.2 million for 2015. In September 2014, the Company and Bioceres, S.A. entered into an agreement to reduce the annual commitment for 2014 to $500,000 and to eliminate the 2015 commitment. In consideration for these amendments, the Company surrendered 1,832 shares of Bioceres, S.A. held by the Company. The Company recorded an expense of $1.5 million related to this agreement, which is classified as research and development expense in the Consolidated Statement of Operations and Comprehensive Loss for the year ended December 31, 2014. In addition, the Company had a right to require Bioceres, S.A. to repurchase any shares of common stock then owned by the Company upon the occurrence of certain events specified in the agreement, and similarly, Bioceres, S.A. had the right to require the Company to sell back any shares of common stock owned by the Company under certain circumstances. The Company entered into a subcontracted research agreement in 2015 with Bioceres S.A. and Bioceres Semillas, S.A., a subsidiary of Bioceres S.A. Per the agreement, the Company could pay for these services with a combination of cash and Bioceres S.A. shares. As of December 31, 2015, the liability for the aforementioned research agreement was settled with $205,000 of cash and the remaining 632 Bioceres S.A. shares with a fair value of $500,000 held by the Company, thus reducing the cost investment on the Consolidated Balance Sheet to $0. Under the terms of the joint development agreement, the Company has incurred direct expenses and allocated overhead in the amount of $1.3 million and $1.0 million for the year ended December 31, 2015 and 2014, respectively.

In July 2012, a 36month $8.0 million term note was executed with Moral Compass Corporation (“MCC”), the Company’s largest stockholder, and was subordinate to existing promissory notes and convertible promissory notes. The interest rate on the loan was prime plus 2%, with interest only paid monthly in arrears. The principal was due in full at maturity in July 2015. On November 10, 2014, the Company and MCC entered into an amendment to the term loan under which the maturity date was extended to the first to occur of the following dates: (i) April 1, 2016, (ii) the date of an Event of Default, or (iii) a date designated by MCC, by notice to the Company, no earlier than the 20th day following consummation by the Company of an equity financing with gross proceeds to the Company of at least $50 million. In addition, the interest rate remained at prime plus 2% through December 31, 2014, and was amended to increase to 11% per annum thereafter until maturity. The balance of the note, inclusive of accrued interest, was approximately $8.0 million as of December 31, 2014. Accrued interest of $36,000 was recorded in amounts due to related parties on the balance sheet as of December 31, 2014. This term note, including the principal balance of $8.0 million and accrued interest and prepayment fee of $148,000 was paid in full in April 2015. A prepayment fee of $80,000 was recorded as a loss on extinguishment of debt.

Promissory notes were executed with an unrelated party in August 2013 and November 2013 in the amounts of $2.0 million and $1.1 million, respectively. The interest rate on the notes was 10% with principal and interest due in 36 equal monthly installments over the course of their respective threeyear terms. These notes, including the aggregate outstanding principal balance of $1.6 million and accrued interest and prepayment fee of $44,000, were paid in full in April 2015. A prepayment fee of $37,000 was recorded as a loss on extinguishment of debt.

In April 2015, the Company entered into a loan and security agreement with an unrelated party, under which the Company incurred an aggregate principal amount of $20.0 million in term loan borrowings (the “Term Loans”), proceeds of which were used to repay existing debt with MCC and an unrelated party as described above. Under this loan agreement, interest on the Term Loans accrued at a rate per annum equal to the greater of (i) 9.0% and (ii) a fluctuating rate of interest equal to threemonth LIBOR as in effect from time to time plus 8.74%. The Company was required to make interestonly payments under this agreement from the drawdown dates through April 30, 2016, subject to certain conditions for extension to October 31, 2016. After this date, equal monthly payments of principal and interest would have been required so that all outstanding principal amounts and accrued interest would have been repaid by November 1, 2018. This agreement provided for a right of prepayment with associated prepayment fees and an additional end-of-term payment of $600,000 due upon maturity or when the Term Loans are prepaid in whole or in part to the lenders.

In July 2015, the Company amended the Term Loans to include collateral of certain intellectual property rights in exchange for a waiver of the Company’s obligation to obtain a subordination agreement from Mahyco International Pte, Ltd. (“Mahyco International”) with respect to the indebtedness the Company owed to Mahyco International. If any of these events of default were to occur, the lenders could have accelerated and declared to be immediately due and payable the outstanding principal amount of the Term Loans and the Company’s other payment obligations under the agreement. In the case of a bankruptcy or insolvency event of default, the outstanding principal amount of the Term Loans and the Company’s other payment obligations under the loan agreement automatically would have accelerated and become due and payable. In addition, if an event of default occurred and continued under the loan agreement, the lenders could have exercised certain additional secured creditor remedies against the Company and against the assets that secured the Company’s obligations under the agreement.

As part of the Term Loans, the Company also issued the lenders warrants to purchase 1,503,760 shares of its common stock at an exercise price of $5.32 per share, which were only exercisable in the event that an IPO was not completed prior to September 30, 2015 and would have remained exercisable until November 1, 2018. The Company initially recorded $356,000 for the fair value of the warrants as a liability in the Consolidated Balance Sheets, which was subject to subsequent remeasurement for changes in fair value until exercise or expiration. In addition, the Company concluded that the interest rate adjustment upon nonoccurrence of an IPO was an embedded derivative and recorded $81,000 for the fair value of the embedded derivative as a liability, which was subject to subsequent remeasurement for changes in fair value until exercise or expiration. The proceeds received under the Term Loans, less fees paid to the lender of $290,000, were allocated to the warrant liability and the embedded derivative liability based on their initial fair values with the residual amount recorded as notes payable. The resulting debt discount was to be amortized as interest expense over the term of the Term Loans using the effective interest method. The interest expense related to the debt discount was $301,000 for the year ended December 31, 2015.

In May 2015, upon the completion of the IPO, the warrants were terminated and the right to adjust the interest rate upon nonoccurrence of an IPO was relinquished. As such, the Company released the initial fair value of the warrants and the embedded derivative of $437,000 to other income. The Company recognized interest expense inclusive of the debt discount related to the combined Term Loans of $1.5 million for the year ended December 31, 2015.

Two notes and a warrant purchase agreement (“Convertible Promissory Notes”) were executed in September 2013 and December 2013 with Mahyco International, an affiliate of Maharashtra Hybrid Seeds Company Ltd. (“Mahyco”), which is a licensee of the Company’s technologies. The notes under this agreement were issued in the amounts of $500,000 in September 2013 and $4.5 million in December 2013. The interest rate on the notes was prime plus 2%, compounded monthly over the course of the fiveyear terms ending September and December 2018, and was payable in full on the maturity dates. At any time during the term, the lender could convert all or part of the outstanding balance of the notes (including principal and accrued but unpaid interest) into common stock of the Company at $16.52 per share through December 2016 and at 90% of the most recent offering thereafter.

At its option, Mahyco International could offset future fee payments due from Mahyco to the Company against the outstanding balance of the notes (including principal and accrued but unpaid interest). Mahyco International had the right to demand immediate settlement of a portion of the outstanding balance of the convertible promissory notes, subject to mutual agreement by the Company. The Company recorded a derivative liability for the initial fair value of the settlement obligation. In addition, the lender had the right, at its option, to place another $5.0 million of convertible debt with the Company during the fiveyear term. The Company recorded an additional derivative liability for the initial fair value of the Company’s obligation to issue the additional $5.0 million of convertible promissory notes. Changes in the fair value of the derivative liabilities were recorded to other income (expense), net in the Consolidated Statement of Operations and Comprehensive Loss.

In conjunction with the notes, the Company issued to the lender a warrant to purchase 75,666 shares of common stock at an exercise price of $16.52. The warrant was issued in December 2013, vested immediately and remains exercisable throughout the original fiveyear term. The Company allocated the gross proceeds from the notes to the derivative liabilities based on their initial fair values and the remainder of the proceeds to the convertible promissory note and warrants on a relative fair value basis. The amount allocated to the common stock warrant was recorded as a debt discount to be amortized as interest expense over the estimated term of the loan agreement using the effective interest rate method. The Company recognized interest expense related to the convertible promissory note of $747,000 and $725,000 for the years ended December 31, 2015 and 2014, respectively. Of the total interest expense recognized, $536,000 and $483,000 were related to the debt discount for the years ended December 31, 2015 and 2014, respectively. In March 2015, the parties amended the warrant to clarify certain terms relating to expiration. The Company accounted for the amendment as a modification with the incremental increase in fair value of $197,000 as of the amendment date, which was accounted for as a deemed dividend to the warrant holder.

In December 2015, the Company entered into a new loan and security agreement with Silicon Valley Bank (the “Bank”) providing for a senior secured term loan facility in the amount of $25.0 million. Proceeds were used by the Company to repay all existing debt including the Term Loans’ principal balance of $20.0 million and related accrued interest, prepayment and other fees in the amount of $1.3 million and the Convertible Promissory Notes’ principal balance of $3.7 million and associated accrued interest of $154,000. The Term Loans’ prepayment and end of term fees of $1.2 million were recorded as a loss on extinguishment of debt, along with the $427,000 unamortized debt discount and $58,000 of deferred loan issuance fees. In addition, Mahyco International’s option to place another $5.0 million of convertible debt was surrendered with the repayment and the related derivative liabilities totaling $1.6 million were released and recorded as a gain on extinguishment of debt.

Under this new loan and security agreement, interest accrues at a floating rate per annual rate equal to nine tenths of one percentage point (0.90%) above the prime rate published from time to time in The Wall Street Journal. The agreement requires the Company to make monthly interest-only payments through December 2017. After this date, the Company is required to make thirty-six (36) equal monthly installments of principal, plus accrued interest. The Company’s final payment, due on the maturity date of December 1, 2020, shall include all outstanding principal and accrued and unpaid interest plus a final payment equal to $600,000. In the event the loan is repaid prior to its maturity, a prepayment fee is due equal to 3% of the outstanding principal amount if prepayment occurs after December 29, 2016 but on or before December 29, 2017, and 1% of the outstanding principal amount if the prepayment occurs after December 29, 2017. The loan has been recorded on the Consolidated Balance Sheet as of December 31, 2015, net of issuance fees.

This loan and security agreement contains customary events of default and covenants, including a financial covenant that requires the Company to maintain either a liquidity ratio (defined as the ratio of the Company’s cash, cash equivalents and net accounts receivable to the Company’s obligation owed to the Bank) or at least 1.4:1.0, or to cash collateralize 100% of the Company’s obligations to the Bank. The Company’s obligations to the Bank are secured by substantially all of the Company’s assets, excluding intellectual property.

Minimum principal payments on the Company’s outstanding debt related to the new term loan as of December 31, 2015 are as follows (in thousands):

Loss on Debt Extinguishment

The Company recognized a loss on debt extinguishment of $230,000 and $0 for the years ended December 31, 2015 and December 31, 2014, respectively. The loss was comprised of prepayment fees, deferred issuance fees and the release of derivative liabilities related to repaid debts noted above.

Common Stock and Redeemable and Convertible Preferred Stock

Note 10. Common Stock, Redeemable Convertible and Convertible Preferred Stock

Redeemable convertible and convertible preferred stock as of December 31, 2014 consisted of the following:

	Shares Authorized		Shares Issued and Outstanding		Net Carrying Value		Aggregate Liquidation Preference
	(In thousands, except share data)
Series A		68,000,000		16,765,775	$	23,324	$	67,063

Total redeemable convertible and convertible preferred stock		105,140,116		32,972,793	$	82,881	$	130,043

On March 28, 2014, the Company entered into an agreement with certain investors to issue 9,587,764 shares of its Series D redeemable convertible preferred stock at an original issue price of $3.36 per share, and closings that were scheduled to be completed within 90 days from the initial closing date. The holders of the Series D stock also received warrants for the purchase of an aggregate of 1,227,783 shares of common stock, with an exercise price of $18.16 per share, and exercisable at any time within five years from the date of issuance. The warrants issued to Series D stockholders were freestanding instruments that were classified within equity. The proceeds from the issuance of the Series D stock and common stock warrants were allocated based on their relative fair values. The resulting discount from the issuance of the common stock warrants was adjusted against the Series D stock with a corresponding increase in additional paid-in capital. The Company incurred direct and incremental issuance costs of approximately $194,000 related to the Series D stock. The Company recorded the proceeds from the Series D stock, as well as Series A, Series B and Series C convertible preferred stock, net of issuance costs and common stock warrants issued.

The Company also incurred transaction costs for an advisor of approximately $2.1 million, which included a warrant for the purchase of 33,445 shares of common stock issued to the advisor with a fair value of approximately $93,000. This common stock warrant has an exercise price of $13.44 per share, is exercisable anytime within five years from the date of issuance and is recorded within the Company’s equity. As these transaction costs are not considered direct issuance costs, the $2.1 million is included in selling, general and administrative expenses for the year ended December 31, 2014.

In connection with the issuance of the Series D stock and the subsequent amendment to the Articles of Incorporation, the Company reclassified the Series A, Series B and Series C stock outside of stockholders’ deficit because, in the event of certain deemed liquidation events that are not solely within its control, the shares would have become redeemable at the option of the holders. The Company did not adjust the carrying values of the Series A, Series B, Series C stock to the liquidation values of such shares, since a liquidation event was not probable at any of the balance sheet dates.

As the Series D stock was redeemable at the request of the holder on or after the eight-year anniversary from the original issuance date, the Company classified the Series D shares outside of stockholders’ deficit because of the date of redemption that was not within the control of the Company. The Company accreted the carrying value of the Series D stock to the redemption amount on the eighth anniversary using the interest method through periodic charges to additional paid-in capital, which amounted to $2.6 million and $3.7 million for the years ended December 31, 2015 and 2014, respectively. The redemption amount was to be the greater of (i) two times the original issue price of the Series D stock plus accrued and unpaid dividends through the redemption date, or (ii) the fair market value of the Series D stock. The redemption value also included dividends which were payable in arrears upon redemption and would aggregate to $97.0 million over the redemption period of eight years. The redemption amount of outstanding Series A, Series B and Series C stock was equal to its liquidation value, or $4.00 per share.

Note 11. Stock-Based Compensation

Stock Incentive Plans

The Company has two equity incentive plans: the 2006 Stock Plan (“2006 Plan”) and the 2015 Omnibus Equity Incentive Plan (“2015 Plan”).

In February 2006, the Company adopted the 2006 Plan, which provided for the granting of stock options to executives, employees, and other service providers under the terms and provisions established by the Board of Directors. The Company granted options under the 2006 Plan until May 2015, at which time it was terminated with respect to future awards, although it continues to govern the terms of options that remain outstanding under the plan. Certain options vested upon completion of the IPO and the remaining unvested options vest over original service periods between two-and-a-quarter and four years.

In May 2015, the 2015 Plan became effective upon the IPO and all shares that were reserved, but not issued, under the 2006 Plan were assumed by the 2015 Plan. Upon effectiveness, the 2015 Plan had 3,087,729 shares of common stock reserved for future issuance, which included 212,729 shares under the 2006 Plan that were transferred to and assumed by the 2015 Plan. The 2015 Plan provides for automatic annual increases in shares available for grant, beginning on January 1, 2016. In addition, shares subject to awards under the 2006 Plan that are forfeited or terminated will be added to the 2015 Plan.

The 2015 Plan provides for the grant of incentive stock options (“ISOs”), within the meaning of Section 422 of the Code, to our employees and for the grant of nonstatutory stock options (“NSOs”), stock appreciation rights, restricted stock, restricted stock units, performance units, and performance shares to our employees, directors, and consultants. The ISOs and NSOs will be granted at a price per share not less than the fair value at date of grant. Options granted generally vest over a four-year period, with 25% vesting at the end of one year and the remaining vesting monthly thereafter. Options granted generally are exercisable for 10 years, the maximum contractual period.

As of December 31, 2015, a total of 3,153,265 shares of common stock were reserved for issuance under the 2015 Plan, of which 3,108,265 shares of common stock are available for future grant. In connection with the IPO, and as contemplated by the Company’s Director Compensation Policy, the Company granted options to purchase an aggregate of 45,000 shares to three new members of the Board of Directors who joined the Board in connection with the IPO. As of December 31, 2015, a total of 3,382,509 and 45,000 options are outstanding under the 2006 and 2015 Plans, respectively.

The following is a summary of stock option information and weighted average exercise prices under the Company’s stock incentive plans (in thousands, except share data and price per share):

	Shares Subject to Outstanding Options			Weighted- Average Exercise Price Per Share		Aggregate Intrinsic Value
Outstanding — Balance at December 31, 2013		3,682,815		$	2.88	$	39,346
Options granted		125,000			6.12
Options exercised		(17,473	)		1.12
Options cancelled and forfeited		(30,503	)		3.56
Outstanding — Balance at December 31, 2014		3,759,839		$	3.00	$	12,499
Options granted		352,494			7.30
Options exercised		(609,066	)		0.59
Options cancelled and forfeited		(75,758	)		7.33
Outstanding — Balance at December 31, 2015		3,427,509		$	3.76	$	3,707
Options vested and exercisable — December 31, 2015		3,114,037		$	3.41	$	3,707

Aggregate intrinsic value represents the difference between the exercise price of the options and the estimated fair value of the Company’s common stock determined by the board of directors for each of the respective periods. The intrinsic value of options exercised was $1.5 million and $74,000 for the years ended December 31, 2015 and 2014, respectively.

As of December 31, 2015, there was $698,000 of unrecognized compensation cost related to unvested stock-based compensation grants that will be recognized over the weighted-average remaining recognition period of 2.04 years.

In determining the fair value of the stock-based awards, the Company uses the Black-Scholes option-pricing model and assumptions discussed below. Each of these inputs is subjective and generally requires significant judgment to determine.

Expected Term—The expected term is the estimated period of time outstanding for stock options granted and was estimated based on historical, as well as anticipated future, exercise activity.

Expected Volatility—Since the Company was privately held and does not have a long trading history for its common stock, the expected volatility was estimated based on the average volatility for comparable publicly traded biotechnology companies over a period equal to the expected term of the stock option grants. When selecting comparable publicly traded biotechnology companies on which it has based its expected stock price volatility, the Company selected companies with comparable characteristics to it, including enterprise value, risk profiles, position within the industry, and with historical share price information sufficient to meet the expected life of the stock-based awards. The historical volatility data was computed using the daily closing prices for the selected companies’ shares during the equivalent period of the calculated expected term of the stock-based awards. The Company will continue to apply this process until a sufficient amount of historical information regarding the volatility of its own stock price becomes available.

Risk-Free Interest Rate—The risk-free interest rate is based on the interest rate of U.S. Treasuries of comparable maturities on the date the options were granted.

Expected Dividend—The expected dividend yield is based on the Company’s expectation of future dividend payouts to common stockholders.

The fair value of stock option awards to employees was estimated at the date of grant using a Black-Scholes option-pricing model with the following weighted-average assumption:

	Year Ended December 31,
Assumptions	2015			2014
Expected term (years)		5.52			5.50
Expected volatility		100	%		129	%
Risk-free interest rate		1.61	%		1.75	%
Expected dividend yield		—	%		—	%

The weighted- average, estimated grant-date fair value of employee stock options granted during the year ended December 31, 2015 and December 31, 2014 was $4.64 and $4.32, respectively. The Company recognized $1.3 million and $976,000 of compensation expense for stock options to employees and nonemployees for the years ended December 31, 2015 and 2014, respectively.

Employee Stock Purchase Plan

In May 2015, the Company’s 2015 Employee Stock Purchase Plan (“ESPP”) was introduced. The ESPP allows eligible employees to purchase shares of the Company’s common stock at a discount through payroll deductions of up to 15% of their eligible compensation, subject to any plan limitations. After the first offering period, which began on May 14, 2015 and ended on February 1, 2016, the ESPP provides for six-month offering periods, and at the end of each offering period, employees are able to purchase shares at 85% of the lower of the fair market value of the Company’s common stock on the first trading day of the offering period or on the last day of the offering period. The initial number of shares of common stock reserved for issuance under the ESPP is 625,000, and the ESPP provides for automatic annual increases in the shares available for purchase beginning on January 1, 2016. As of December 31, 2015, no shares had been issued under the ESPP. The Company recorded $69,000 of compensation expense and $145,000 of current liability from employee contributions related to the ESPP for the year ended December 31, 2015.

Leases

The Company leases office and laboratory space, greenhouse space, grain storage bins, warehouse space, and equipment under operating lease agreements having initial lease terms ranging from three to five years, including certain renewal options available to the Company at market rates. The Company also leases land for field trials on a short-term basis. Future minimum payments under non-cancelable operating leases in effect as of December 31, 2015, are presented below (in thousands):

Years Ending December 31,	Amounts

Total future minimum payments under non- cancelable operating leases	$	2,057

Rent expense under all operating leases totaled $1.3 million and $1.0 million for the years ended December 31, 2015 and 2014, respectively.

Legal Matters

From time to time, in the ordinary course of business, the Company may become involved in certain legal proceedings. As of December 31, 2015 and 2014, the Company was not involved in any legal proceedings.

Contingent Liability Related to the Anawah Acquisition

On June 15, 2005, the Company completed its agreement and plan of merger and reorganization with Anawah, Inc. ("Anawah" or "Sellers"), to purchase the Sellers’ food and agricultural research company through a stock purchase. Pursuant to the merger with Anawah, and in accordance with the ASC 805 - Business Combinations, the Company incurred a contingent liability not to exceed $5.0 million. This liability represents amounts to be paid to Anawah’s previous stockholders for cash collected on revenue recognized by the Company upon commercial sale of certain specific products developed using technology acquired in the purchase. As of December 31, 2010, the Company ceased activities relating to three of the six Anawah product programs and, as a result, reduced the contingent liability to $3.0 million. The Company believes the contingent liability is appropriate as it continues to pursue three development programs using this technology as of December 31, 2015.

Contracts

The Company has entered into contract research agreements with unrelated parties that require the Company to pay certain funding commitments. The initial terms of these agreements range from one to three years in duration and in certain cases are cancelable.

The Company licenses certain technologies via executed agreements (“In-Licensing Agreements”) that are used to develop and advance the Company’s own technologies. The Company has entered into various In-Licensing Agreements with related and unrelated parties that require the Company to pay certain license fees, royalties, and/or milestone fees. In addition, certain royalty payments ranging from 2% to 15% of net revenue amounts as defined in the In-Licensing Agreements will be due.

There is no minimum payment for non-cancelable annual license fees due during the year ended December 31, 2014. Royalties on licensed revenue accrued as of December 31, 2015 and 2014, were $177,000 and $252,000, respectively. Royalties are included within research and development on the Consolidated Statements of Operations and Comprehensive Loss.

Milestone payments are contingent upon the successful development or implementation of various technologies. Payments for milestones yet to be achieved totaled $2.0 million and $2.1 million for the years ended December 31, 2015 and 2014, respectively. The timing of the payments is not determinable at this time pending research and development currently in progress; however, no significant payments were made during the years ended December 31, 2015 and 2014.

The Company could be adversely affected by certain actions by the government as it relates to government contract revenue received in prior years. Government agencies, such as the Defense Contract Audit Agency routinely audit and investigate government contractors. These agencies review a contractor’s performance under its agreements; cost structure; and compliance with applicable laws, regulations, and standards. The agencies also review the adequacy of, and a contractor’s compliance with, its internal control systems and policies, including the contractor’s purchasing, property, estimating, compensation, and management information systems. While the Company’s management anticipates no adverse result from an audit, should any costs be found to be improperly allocated to a government agreement, such costs will not be reimbursed, or if already reimbursed, may need to be refunded. If an audit uncovers improper or illegal activities, civil and criminal penalties and administrative sanctions, including termination of contracts, forfeiture of profits, suspension of payments or fines, and suspension or prohibition from doing business with the government could occur. In addition, serious reputational harm or significant adverse financial effects could occur if allegations of impropriety were made against the Company. There currently are routine audits in process relating to government grant revenues.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes, net operating loss carryforwards (“NOLs”), and other tax credits. Significant components of the Company’s deferred tax assets are as follows (in thousands):

	As of December 31,
	2015			2014
Deferred tax assets:
Net operating loss carryforwards	$	41,807		$	35,227
Unearned revenue		1,421			1,741
Stock-based compensation		2,485			1,971
Accrued payroll and benefits		226			221
Derivative instrument		—			616
Research and development credits		106			75
Capital loss carryover		16			18
Fixed asset basis difference		192			196
Inventory reserve		912			680
Charitable contributions		7			8
Total deferred tax assets		47,172			40,753
Deferred tax liabilities:
Convertible note discount		—			(188	)
Less valuation allowance		(47,172	)		(40,565	)
Net deferred tax assets	$	—		$	—

Realization of the deferred tax assets is dependent upon future taxable income, if any, the amount and timing of which are uncertain. Accordingly, the net deferred tax assets have been offset by a valuation allowance. The net valuation allowance increased by $6.6 million and $6.3 million during the years ended December 31, 2015 and 2014, respectively.

At December 31, 2015, the Company had federal and state NOLs aggregating approximately $118.2 million and $89.1 million, respectively. At December 31, 2015, the utilization of a portion of our NOLs is subject to an annual limitation under Section 382 of the Internal Revenue Code (IRC). Of the $118.2 million generated, $7.2 million will not be available to be utilized within the carryforward period. These federal NOLs will begin to expire in 2020 and these state NOLs will begin to expire in 2016, if not utilized. The Company continues to evaluate IRC Section 382, which may limit NOLs generated in future years.

The Company’s deferred tax asset at December 31, 2015 does not include $2.7 million of excess tax deductions from employee stock option exercises included in its NOLs. The Company’s stockholders’ deficit will be decreased by up to $1.0 million if and when the Company ultimately realizes these excess tax benefits. The Company uses tax law ordering to determine when excess tax benefits have been realized.

The Company evaluates deferred tax assets, including the benefit from NOLs, to determine if a valuation allowance is required. Such evaluation is based on consideration of all available evidence using a “more likely than not” standard with significant weight being given to evidence that can be objectively verified. This assessment considers, among other matters, the nature, frequency, and severity of current and cumulative losses; forecasts of future profitability; the length of statutory carryforward periods; the Company’s experience with operating losses; and tax-planning alternatives. The significant piece of objective negative evidence evaluated was the cumulative loss incurred over the three-period ended December 31, 2015. Given this evidence and the expectation to incur operating losses in the foreseeable future, a full valuation allowance has been recorded against net deferred tax asset. The Company will continue to maintain a full valuation allowance against the entire amount of its net deferred tax asset, until such time as the Company has determined that the weight of the objectively verifiable positive evidence exceeds that of the negative evidence and it is likely that the Company will be able to utilize all of its net deferred tax asset relating to its federal and state NOL carryforwards. Although the Company has established a full valuation allowance on its net deferred tax asset, it has not forfeited the right to carryforward tax losses up to 20 years and apply such tax losses against taxable income in such years, thereby reducing its future tax obligations. The Company is subject to taxation in the United States and various state jurisdictions. As of December 31, 2015, the Company’s tax years for 2005 through 2015 are generally subject to examination by the tax authorities.

The Company applies the provisions of ASC 740 related to accounting for uncertain tax positions and concluded there were no such positions associated with the Company requiring accrual of a liability. As of December 31, 2015, the Company has not accrued for any such positions. The Company is currently not under audit for federal or state purposes. The Company does not expect a significant change to occur within the next 12 months.

Earnings Per Share [Abstract]

Net Loss per Share

Note 16. Net Loss per Share

Basic net loss per share is calculated by dividing net loss attributable to common stockholders by the weightedaverage number of common shares outstanding during the period and excludes any dilutive effects of stockbased awards and warrants. Diluted net loss per share attributable to common stockholders is computed giving effect to all potentially dilutive common shares, including common stock issuable upon exercise of stock options and warrants and conversion of convertible promissory notes, redeemable convertible preferred stock and convertible preferred stock. As the Company had net losses for the years ended December 31, 2015 and 2014, all potentially dilutive common shares were determined to be antidilutive.

Securities that were not included in the diluted per share calculations because they would be antidilutive were as follows (in shares):

	Year Ended December 31,
	2015		2014
Convertible preferred stock		—		23,385,029

Repayment date of outstanding principal amounts and accrued interest			Nov. 01, 2018
Debt instrument, violation or event of default description			In July 2015, the Company amended the Term Loans to include collateral of certain intellectual property rights in exchange for a waiver of the Company’s obligation to obtain a subordination agreement from Mahyco International Pte, Ltd. (“Mahyco International”) with respect to the indebtedness the Company owed to Mahyco International. If any of these events of default were to occur, the lenders could have accelerated and declared to be immediately due and payable the outstanding principal amount of the Term Loans and the Company’s other payment obligations under the agreement. In the case of a bankruptcy or insolvency event of default, the outstanding principal amount of the Term Loans and the Company’s other payment obligations under the loan agreement automatically would have accelerated and become due and payable. In addition, if an event of default occurred and continued under the loan agreement, the lenders could have exercised certain additional secured creditor remedies against the Company and against the assets that secured the Company’s obligations under the agreement.
