For its part, the Treasury appeared to be opposed to any options that did not involve making the banks whole on their A.I.G. contracts. At Treasury, a former Goldman executive, Dan H. Jester, was the agency’s point man on the A.I.G. bailout. Mr. Jester had worked at Goldman with Henry M. Paulson Jr., the Treasury secretary during the A.I.G. bailout. Mr. Paulson previously served as Goldman’s chief executive before joining the government.

A Close Association

Mr. Jester, according to several people with knowledge of his financial holdings, still owned Goldman stock while overseeing Treasury’s response to the A.I.G. crisis. According to the documents, Mr. Jester opposed bailout structures that required the banks to return cash to A.I.G. Nothing in the documents indicates that Mr. Jester advocated forcing Goldman and the other banks to accept a discount on the deals.

Although the value of Goldman’s shares could have been affected by the terms of the A.I.G. bailout, Mr. Jester was not required to publicly disclose his stock holdings because he was hired as an outside contractor, a job title at Treasury that allowed him to forgo disclosure rules applying to appointed officials. In late October 2008, he stopped overseeing A.I.G. after others were given that responsibility, according to Michele Davis, a spokeswoman for Mr. Jester.

Ms. Davis said that Mr. Jester fought hard to protect taxpayer money and followed an ethics plan to avoid conflict with all of his stock holdings. Ms. Davis is also a spokeswoman for Mr. Paulson, and said that he declined to comment for this article.

The alternative bailout plans that regulators considered came from three advisory firms that the New York Fed hired: Morgan Stanley, Black Rock, and Ernst & Young.

One plan envisioned the government guaranteeing A.I.G.’s obligations in various ways, in much the same way the F.D.I.C. backs personal savings accounts at banks facing runs by customers. On Oct. 15, Ms. Dahlgren wrote to Mr. Geithner that the Federal Reserve board in Washington had said the New York Fed should try to get Treasury to do a guarantee. “We think this is something we need to have in our back pockets,” she wrote.

Treasury had the authority to issue a guarantee but was unwilling to do so because that would use up bailout funds. Once the guarantee was off the table, Fed officials focused on possibly buying the distressed securities insured by A.I.G. From the start, the Fed and its advisers prepared for the banks to accept discounts. A BlackRock presentation outlined five reasons why the banks should agree to such concessions, all of which revolved around the many financial benefits they would receive. BlackRock and Morgan Stanley presented a number of options, including what BlackRock called a “deep concession” in which banks would return $6.4 billion A.I.G. paid them before the bailout.
