Fannie Mae Preferred S (FNMAS)

[jwnoble3]

Found it -
Also each GSE contracted to issue common stock warrants representing an ownership stake of 79.9%, at an exercise price of one-thousandth of a U.S. cent ($ 0.00001) per share, and with a warrant duration of twenty years.[29]

Appears TSY can buy GSE commons at .00001/shr for ~15 more years. I'd keep them alive to make a profit
