Fastow disclosed to Enron's board of directors on October 22 that he earned $30 million from compensation arrangements when managing the LJM limited partnerships. That day, the share price of Enron decreased to $20.65, down $5.40 in one day, after the announcement by the SEC that it was investigating several suspicious deals struck by Enron, characterizing them as "some of the most opaque transactions with insiders ever seen". Attempting to explain the billion-dollar charge and calm investors, Enron's disclosures spoke of "share settled costless collar arrangements," "derivative instruments which eliminated the contingent nature of existing restricted forward contracts," and strategies that served "to hedge certain merchant investments and other assets." Such puzzling phraseology left many analysts feeling ignorant about just how Enron managed its business. Regarding the SEC investigation, chairman and CEO Lay said, "We will cooperate fully with the SEC and look forward to the opportunity to put any concern about these transactions to rest."
