Doug Ostrover, head of high-yield sales, trading and distressed credits at Credit Suisse First Boston, has added junk reserach chief to his growing list of management responsibilities. "Doug has been the de-facto head for some time, so we decided to make it official," says Bennett Goodman, CSFB's global head of leveraged finance. As a result of the change, Sam DeRosa-Farag and Tom Klamka, co-heads of high-yield research will report to Ostrover instead of Goodman. Ostrover joined the high-yield sales desk at Donaldson, Lufkin & Jenrette some 10 years ago, and was promoted to head of sales in 1997.
