A federal judge has ordered a one-month delay in the Enron-related May retrial of a former Merrill Lynch executive.

U.S. District Judge Ewing Werlein Jr. agreed to delay Robert S. Furst's retrial to June 1 to accommodate plea negotiations. Prosecutors and defense attorneys told Werlein during a hearing Friday that they are close to a deal that would resolve the case.

Furst and two other executives were convicted in 2004 of helping push through Enron's sham sale to Merrill Lynch of three power barges moored off the Nigerian coast in 1999. The deal was struck to make the Enron energy division's earnings appear larger.

But an appeals court threw out their fraud and conspiracy convictions in 2006 after finding fault with the prosecution's legal theory.
