It was the bank manager of my mothers bank in South Carolina who explained it to me.
I have tried to verify it on any website, but there is no mention of how payments would be made
However, knowing how underfunded so many plans are, I wouldn't be surprised if they have the option to extend payments out over years
The FDIC system was meant to handle one or two bank collapses.
The big question is what if a number of banks were to close in an unexpected national banking crisis? The system wasn't created for that degree of stress
