Dr. Peter Xie, President and CEO of the Company, commented, “Our new ticker, HSOL, represents the completion of our corporate rebranding effort, following last year’s significant investment from Hanwha Chemical Corporation and our company’s subsequent name change to ‘Hanwha SolarOne Co., Ltd.’ on December 20, 2010.
