as of aug 2014:
With its previous payments totaling $126.7 billion, Fannie has more than fully repaid the $116 billion it received from taxpayers. Washington-based Fannie will pay a dividend of $3.7 billion to the U.S. Treasury next month
total paid 130.4 billion, total from treasury 116 billion. 130-116= 14 billion extra.
so of the 1.2 billion shares outstanding this would be about $10 a share as of august 2014.
Fannie has no debt, this has been taken care of by the bailout of the firm and only debt is to the treasury. That has been paid back in full.
Each quarter that fannie sends another 3.7 billion to treasury would add another $3 to each share in liquidation.
An example would be that august of next year the share price would be around $22 a share upon liquidation.
This all hinges on the fact that the govt has been paid back all with interest, and the sweep is illegal.
