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. Similar to the new company name, the HSOL ticker conveys Hanwha SolarOne’s enhanced capabilities and synergies with our largest shareholder, and we believe its implementation will fully solidify our new identity on the trading floor.”
