A famous private equity company in Shanghai made an investment agreement with a company in Zhenjiang, Jiangsu Province in the end of 2007. The PE invested in the company at a premium, and the parties mutually agreed in the agreement that the percentage of equity of parties would be adjusted based on the profit of 2008. In fact, the Zhenjiang company was far from the profit object provided in the agreement in virtue of the financial crisis. Therefore, the PE requested for an adjustment according to the agreement, but the Zhenjiang company responsed nagatively. On behalf of the PE, Mr. Chambers Yang and his team conducted a all-round analysis concerning the effect and legal status of the value adjustment clause, the Zhenjiang company's possible defenses and corresponding countermeasures, risks and strategy of litigation, etc.
