Michael Robert Milken is an American financier. He is known for his role in the development of the market for high-yield bonds ("junk bonds"), which led to his reputation as the "Junk Bond King", and his conviction and sentence following a guilty plea on felony charges for violating U.S. securities laws. Milken's compensation while head of the high-yield bond department at Drexel Burnham Lambert in the late 1980s exceeded $1 billion over a four-year period, a record for U.S. income at that time. With a net worth of $6 billion as of 2022, he is among the richest people in the world.
Milken was indicted for racketeering and securities fraud in 1989 in an insider trading investigation. In a plea bargain, he pleaded guilty to securities and reporting violations but not to racketeering or insider trading. Milken was sentenced to ten years in prison, fined $600 million (although his personal website claims $200 million) and permanently barred from the securities industry by the U.S. Securities and Exchange Commission. His sentence was later reduced to two years for cooperating with testimony against his former colleagues and for good behavior.
