Fannie Mae (FNMA)

[SGINPHX]

So I have been trying to wrap my head around the dollars. FNMA was profitable from 03-06 showing anywhere from 4-8 billion profit/yr. 07 hits and they have a loss but are forced to go mark-market which means a 59B loss that eats up the 41B reserves they had leaving an 18B deficit. 08-11 they take 116.1B (15.2/60/15/25.9)draws = 134.1B negative but show losses of 161.4B(58.7/72/14/16.4). I know the accounting is bad and caused the write downs but I am not looking at that right now. They pay out 20.1B in dividends ( .03/2.5/7.7/9.6). Then from 12-current they are profitable 131.7B (11.6/82.5/20.6/10.3/6.7 thru 3Q). By my math they owed 1.5/7.5/9/16.1 in dividends if paid at 10% = 34.1B. In my head they have been thrown into the NWS over 14B that has paid out over 131B to date. Had the 10% rate held in lieu of the NWS we would owe the 14 plus another 58B(11.6 x 5 years) which would leave a balance of 73.7B at this years end plus we would have kept the payments from court cases (banks??) correct? This could have been used to grow the business instead of having our capital depleted.
Now..had we been allowed to pay back the loan, like EVERY other bailout company did we would have paid down the 116.1B 2012 we showed an 11.6 profit less an 11.6 payment. 2013 82.5B less the 11.6 left 71B which would have left a balance of 45B and changed the dividend payouts drastically. 2014 we made 20.6 and would have paid 4.5B. Payoff another 16.1B (28.9 balance) 2015 we made 10.3 and would have paid 2.89 and paid off another 7.4B (21.5B Balance) and this year to date we are at 6.7 with a payment owed of 1.2YE would pay another 5+ and still have a balance of 16+-. I get that this is simple math and we would have gained by making payments quarterly and lessened the balance faster. I also understand that the company could have diluted shares to raise capital and paid off earlier potentially in 2013 and saved the 20B that would have been paid in dividends.
Question...what else am I missing??? Other than the fact that this should have never happened in the first place!
