The firm is 20 percent owned by Madoff and 80 percent owned by Maurice Cohn--its name is a combination of their names. Cohmad's New York office is in the same building as Madoff's. An executive has said that the firm was unaware of the fraud. There are a lot of questions that need to be answered here. Hopefully, Madoff himself, will let the world in on his secrets.
