Looks like about 18 percent, although I would assume there's a particular demographic where this might be higher.
Do they have to be paid out in full, though? I remember cases in the past where a company went bankrupt and had to renege on some parts of pensions, so maybe you'll see that again?
After some percentage are reneged… there would still be a strongly motivated bloc of considerable size?
I don’t see how it is relevant, unless the rate is close to 100%.
