Two days later, on November 21, Wall Street expressed serious doubts that Dynegy would proceed with its deal at all, or would seek to radically renegotiate. Furthermore, Enron revealed in a 10-Q filing that almost all the money it had recently borrowed for purposes including buying its commercial paper, or about $5 billion, had been exhausted in just 50 days. Analysts were unnerved at the revelation, especially since Dynegy was reported to have also been unaware of Enron's rate of cash use. In order to end the proposed buyout, Dynegy would need to legally demonstrate a "material change" in the circumstances of the transaction; as late as November 22, sources close to Dynegy were skeptical that the latest revelations constituted sufficient grounds. Indeed, while Lay assumed that one of his underlings had shared the 10-Q with Dynegy officials, no one at Dynegy saw it until it was released to the public. It subsequently emerged that Enron's traders had grabbed much of the money from Dynegy's cash infusion and used it to guarantee payment to their trading partners when it came time to settle up.
