I did a little investigating and found the following information about TPG:
Texas Pacific Group Company Profile
From
Yahoo FinanceYee-haw! Let's round us up some LBOs! Texas Pacific Group (TPG) has staked its claim on the buyout frontier with a reputation for roping in companies other investors wouldn't touch with a 10-foot pole. An active investor, TPG often takes control of the companies in which it invests. Holdings have included stakes in technology (Seagate Technology, ON Semiconductor), consumer franchises/products (Burger King, Ducati), retailers (J. Crew, Petco), airlines (Continental, America West), and entertainment (Metro-Goldwyn-Mayer). Texas Pacific Group raised a whopping $15 billion for a Texas-sized buyout fund in 2006.
It appears that TPG focus is to invest in companies that have potential but are a bit risky.
