It was a very good year for Howard Marks and Bruce Karsh, two co-founders of Oaktree Capital Management. They sold 16 percent of their L.A. money management firm on a private Goldman Sachs exchange in May, raising $1 billion. Now they each have a net worth of $1.4 billion and wound up 361st position on the Forbes 400. By the way, Marks is a former assistant to Eli Broad at SunAmerica. In 1995, he and Karsh founded Oaktree, which now has assets of $47 billion.
