Why would it be important from an accounting and ethical perspective for Enron to disclose information about the guarantee in its financial statements?

In the Enron case, the company eventually turned to “back-door” guaranteeing of the debt of Chewco, one of its SPEs, to satisfy equity investors. Assume that a $16 million loan agreement required that Enron stock should not fall below $40 per share. If the share price did decline below that trigger amount, either the loan would be called by the bank or the bank could choose to increase the guaranteed number of Enron shares based on the new price (assume $32). If the bank decides to increase the number of shares guaranteed, what would be (1) the original number of shares in the guarantee and (2) the new number of shares?
