Whatever you’re doing now will be converted to keeping track of the money.
That's why god invented money managers ;-) I bet I could get my financial adviser to give me a discount! Even at 1/10 of a basis point, that would be close to $1M/year in fees on the lump sum payout. Chicken feed compared to the $70M/year long term average return you could make w conservative investments. The hardest part would be managing the charitable foundation. First world problems, indeed!
