Premium on FFN may be explained by ATM program.So FTN actually has more preferreds outstanding than commons.
WITH FFN it is the opposite . At last count there are 55,220,000 commons out and only 54,021,000 preferreds out. My guess is that FFN will halt the ATM for commons and push the BUY at MArket for preferreds to get it back to level numbers. AS well , if FFN preferreds stay down until DEC 2024, FFN will see the same thing happen that FTN saw when they consolidated. Will be a lot of FFN preferreds getting cashed in @ 10$ and then a consolidation will have to happen, to bring the number of shares in each back to even number. Unless of course , FFN preferreds get back to 10$ valuation ( or higher) a month before the termination date of the fund.
