Former Enron Corp. Treasurer Ben Glisan, testifying Thursday at the federal fraud trial of Kenneth Lay and Jeffrey Skilling, admitted he could not remember Skilling’s exact words about skirting accounting rules.

Skilling’s lead defense attorney, Daniel Petrocelli of O’Melveny & Myers, questioned Glisan’s memory about what Skilling said at a meeting about how Enron could use off-the-books partnerships to get around accounting rules.
