Annual payments are $35 million per year after federal tax. Lump sum would be $651 million after federal tax.
No matter how old I am, $35 million would spend just as well as $651 million, and there'd be a revenue stream for the kids and grandkids to have but not abuse.
If you can't trust the multi-state Powerball to pay out, then there's a lot more problems in the country that the lump sum wouldn't solve, either.
Maybe I have it wrong, but I thought that if one dies the annuity payout stops. If you're in your 60’s or 70’s, take the annuity, die within a few years, your survivors get a lot less than if you take the lump sum.
