Emerald is a bioagriculture company developing and manufacturing naturally occurring biochemicals for the enhancement of yield, quality and disease control in crops. We invested largely on the promise of its lead product, a growth-enhancing reagent containing GABA (gamma amino butyric acid), a non-protein amino acid that helps regulate mineral availability in plants. Use of the product can enhance flowering, increase fruit size, improve yields and suppress disease. Our stock in Emerald was repurchased by the company in 2009.
