Private equity group KKR & Co
An agreement with the target company's owners, Arle Capital Partners -- the former buyout arm of Candover Investments
One of the high-profile private equity victims of the credit crunch, Candover last year decided to wind itself up, retaining a small amount of cash for follow-on investment in its portfolio companies.
Candover acquired Milton Keynes-based CSG from Electra Private Equity in 2007 for $565 million. Cinven and Warburg Pincus were among the buyout firms that looked at taking over CSG recently, the Financial Times reported last month.
