Three former executives from Merrill Lynch surrendered to federal authorities Wednesday to face criminal charges stemming from an illegal transaction that helped Enron Corp. record a bogus $12 million profit and boost its quarterly earnings in 1999, according to the Department of Justice. Daniel Bayly, the former head of the global investment banking division at Merrill Lynch; James A. Brown, head of Merrill Lynch's strategic asset lease and finance group; and Robert S. Furst, the Enron relationship manager for Merrill Lynch in the investment banking division, are accused of knowingly participating in a sham sale of three barges moored off the Nigerian coast. All three surrendered at the Houston office of the FBI. A spokesperson at Merrill Lynch declined to comment.
