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”), to purchase the food and agricultural research company through a non-cash 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, thus, the contingent liability was reduced to $3.0 million. During the third quarter of 2016, one of the programs previously accrued for was abandoned and another program previously abandoned was reactivated. As of March 31, 2019, the Company continues to pursue three development programs using this technology and believes that the contingent liability is probable. As a result, $3.0 million remains on the Condensed Consolidated Balance Sheet as an other noncurrent liability.
