This is unbeliva entirely believable. From Reuters (via The Business Insider — with thanks to Christopher Reagan):

In May, the SEC approved a request by AIG to keep secret an exhibit to a year-old regulatory filing that includes some of the details on the most controversial aspect of the AIG bailout: the funneling of tens of billions of dollars to big banks like Societe Generale, Goldman Sachs (GS.N), Deutsche Bank (DBKGn.DE) and Merrill Lynch.
The SEC’s Division of Corporation Finance, in granting AIG’s request for confidential treatment, said the “excluded information” will not be made public until Nov. 25, 2018, according to a copy of the agency’s May 22 order.
The SEC said the insurer had demonstrated the information in the exhibit, called Schedule A, “qualifies as confidential commercial or financial information.”

No word yet from Secretary Tim “Don’t Tell ‘Em Nuttin’” Geithner on whether the 2018 release will be broadcast on C-SPAN.
