INDIANAPOLIS — An Indiana man who won last month’s $435.3 million Powerball jackpot has chosen to remain anonymous, collecting the 10th largest lottery jackpot in U.S. history through a limited liability corporation, officials said Monday.

A lump sum of $189.1 million, after federal and state taxes are withheld, will be paid to the LLC set up on behalf of the winner, Hoosier Lottery director Sarah Taylor said at a news conference.

The winner bought five tickets at a convenience store in his hometown of Lafayette on the day of the Feb. 22 drawing, said Jennifer Dzwonar, an Indianapolis public relations official who spoke on behalf of the winner.

When he realized he had won, the Purdue University graduate couldn’t sleep.

The most he’d ever won in the past was $100 from a scratch-off ticket.
