the "advance" is written as an equity investment (preferred stock - not a loan)
all payments so far have been viewed and booked by the GOV as dividends
thus per the GOV nothing has reduced their investment in equity
(the Gov is right by securities law)
I do think that in some arrangement to move forward by congress or in some deal - that the GOV could quickly agree that its investment has been paid back
but we need the GOV to do that ...... and legally nothing has been paid back - all is a dividend on senior preferred (equity) stock
