Quote from UST reform plan-
"FHFA has approved the GSE’s capital restoration plan, and the GSE has retained or raised sufficient capital and other loss-absorbing capacity to operate in a safe and sound manner;"
Don't mention core capital again. Loss absorbing capacity including DTA, hedging, new credit line from UST (with fee),.... shall be part of GSE capital restoration plan.
By end of Sept you will know how significant retained earning is.
