$327.4 million, per the Powerball site
Right now federal taxes eat 35% (top marginal rate)that leaves $212.8 million pre-state taxes. Lucky I am in Texas so I will bank the 212.8.
There is a ranch in Colorado I have been eyeing that I would own before Christmas - that's $25 mill; at least 10% to a charitable trust for long term giving. Set aside around $20 million for me to play with in the market and put the rest into tax free bonds and try to draw 3.5% after taxes and live off the $7 million or so a year.
Not that I have been giving it much thought...
