How to Invest $540 Mega Millions (SmartMoney)

After taxes, the lump-sum payout would be closer to half, but still more than enough to support a lavish lifestyle if invested correctly. Invested very conservatively, that sum kept in three-month Treasury bills would earn over $200,000 a year. Advisors stress there is no need to be that conservative. Putting half the winnings in high-grade municipal bonds could bring in $3 million a year. Another 40% of the winnings in high-quality corporate bonds could earn $2 million a year. And to keep up with inflation, put the rest in dividend paying stocks. All told, the winner could get about $7 million a year without having to touch the prize money.
