Variable Interest Entity	6. Variable Interest Entity In February 2012, the Company formed Verdeca LLC (“Verdeca”), which is equally 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 cooperative 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.

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, 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 a research and development expense of $1.5 million related to this agreement during 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 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 Company’s Condensed Consolidated Balance Sheet to $0. Under the terms of the joint development agreement, the Company has incurred direct expenses and allocated overhead in the amounts of $261,000, $487,000, $98,000, and $221,000 for the three and nine months ended September 30, 2017 and 2016, respectively.
