Banks getting wiped out because of bad loans has pretty much become a regular feature these days. But when a global private equity firm of repute loses money hand over fist, you cannot not sit up and ask what just went wrong. KKR & Co. founded by Jerome Kohlberg Jr, Henry Kravis and George Roberts is a behemoth on Wall Street with assets under management of $190 billion across private and public markets. It has a storied history, having the distinction of clocking some of the biggest leveraged buyouts, right from the LBO of RJR Nabisco in a $25 billion deal way back in 1989 to the record buyout of Energy Future Holdings at $48 billion in 2007, the largest LBO thus far in US history.
