Warren Buffett’s Berkshire Hathaway Inc. is backing a $1 billion prize offered by Quicken Loans Inc. if a contestant predicts the winner of each game in the National Collegiate Athletic Association’s men’s basketball tournament.

The prize will be paid in 40 annual installments of $25 million and split among multiple winners if there is more than one perfect entrant, the Detroit-based lender said Monday in a statement. The winner also has the option of a single payment of $500 million.
