TPG Capital

Bidders may be lining up for Sara Lee as private equity firm Apollo assembles an investor group to explore a possible offer and Brazilian meat-processor JBS considers coming back with a better deal.

Private-equity firms Apollo Management and TPG, which took Harrah's Entertainment private in January 2008, are now preparing a $575 million initial public offering. An IPO may be just as bold a move as the buyout, as investors remain wary of IPOs from private-equity firms.

Private equity firm TPG Capital has agreed to pay $1.3 billion for American Tire Distributors.
