Bill Clinton’s old lawyer, Robert S. Bennett, disclosed that last year Ken Lay used Enron stock to repay a loan extended to him by the company. He hasn’t come clean about when the loan was repaid, so we don’t know how much the stock was worth when he repaid the loan or whether he repaid it after the date he claimed he stopped selling Enron stock. The implications here are that Lay liquidated more stock than he previously disclosed — he just liquidated it in a different way. Depending on any number of factors, there may be nothing to this at all, or it may be a big deal.
