"“Outstanding preferred”? Are they referring to senior prefs?"
FnF are paying now punitive interests rates on drawn SPS value (currently it is usury 10% dividend).
Commitment fee is on non drawn amount. FnF do not need $256B credit line. The credit line can be up to an amount to bring capital to meet the capital requirements.
At the same time all social mandates imposed on FnF should be paid by Gov at cost + 15% fee.
