Not sure what you meant by "choose KRIP", as everyone has KRIP (Kodak Retirement Income Plan).
When you retired, pre-BK, you could take it as a lump-sum, or a couple of different annuity options if you are married.
If you retired after BK, you could only take KRIP as an annuity but once EK emerges from BK, you have the option of getting the rest as a lump sum, under some set of rules that HR explained but I don't remember.
So the way I understand it, I don't think anyone's KRIP is at risk. You just might not get it all at once.
