Prior to the "conservatorship" in 2008, they were 100% private corporations, with their shares trading under the symbol ""FNM", for Fannie Mae on the NYSE.
Da gubment, under their "generous terms", in the SPSA, have a Warrant they can exercise until September 2028 that allows them to sell 79.9% (80% and they would have to put the gses on the federal books, along with that pesky $6.5T in MBS liabilities) of the company.
But IF the UST decides not to exercise the Warrants, then I believe that current FNMA holders would still own 100% of these private corporations.
Do you know anything different?
