SUBSEQUENT EVENTS

On February 1, 2016, the Company signed an asset purchase agreement with Sanimax Energy, LLC ("Sanimax") to acquire Sanimax’s 20 million gallon nameplate capacity biodiesel refinery located in DeForest, Wisconsin. Under the asset purchase agreement, REG will pay Sanimax approximately $11,000 in cash and will issue 500,000 shares of REG common stock in exchange for the biorefinery and related assets.  REG will also pay Sanimax up to an additional $5,000 in cash over a period of up to seven years after closing based on the volume of biodiesel produced at the plant, which will be re-named REG Madison, LLC.  Sanimax operates a grease processing facility at the same location, although that facility is not part of the acquisition.  The transaction is subject to customary closing conditions.

On March 5, 2016, the Company's board of directors approved a repurchase program of up to $50,000 of the Company's shares of common stock and/or convertible notes, in effect through March 5, 2018. Under the program, REG may repurchase shares or bonds from time to time in open market transactions, privately negotiated transactions or by other means. The timing and amount of repurchase transactions will be determined by the Company's management based on its evaluation of market conditions, share price, bond price, legal requirements and other factors. The program may be suspended, modified or discontinued at any time without prior notice.
