Thanks Vancmike for staying on subject.
As I have stated before, when it suits them, the govt claims the SPS was an investment. At other times that it's a loan. FnF sent their equity to the Treasury until stopped by the Fifth Circuit Enbanc. Since then the the Liquidation Preference has grown for each $ of earnings as per letter of agreement signed between Calabria and Mnuchin. When Fannie states "amounts attributable to Senior Preferred Stock" Fannie is signifying that the SPS is considered a loan.
Also, as I have repeatedly stated, if the SPS were a loan, it was paid back a decade ago. If it was an investment, then the corporations have always been capitalized, and there's been no need for the conservatorship.
