Another major correction of Enron's earnings was announced on November 9, with a reduction of $591 million of the stated revenue of years 1997–2000. The charges were said to come largely from two special purpose partnerships (JEDI and Chewco). The corrections resulted in the virtual elimination of profit for fiscal year 1997, with significant reductions for the other years. Despite this disclosure, Dynegy declared it still intended to purchase Enron. Both companies were said to be anxious to receive an official assessment of the proposed sale from Moody's and S&P presumably to understand the effect the completion of any buyout transaction would have on Dynegy and Enron's credit rating. In addition, concerns were raised regarding antitrust regulatory restrictions resulting in possible divestiture, along with what to some observers were the radically different corporate cultures of Enron and Dynegy.
