DETROIT (AP) - Correctly predicting the outcome of every game in the NCAA men's basketball tournament is no layup. But there's now a $1 billion prize waiting for anyone able to pull off the feat this spring. Quicken Loans announced Tuesday that it's teaming with investor Warren Buffett's Omaha, Neb.-based Berkshire Hathaway on the "Billion Dollar Bracket Challenge." The Detroit-based mortgage lender says any qualified entrant who correctly predicts the winners of every game in the tournament will be paid in 40 annual installments of $25 million. A winner also can elect to receive an immediate $500 million lump-sum payment or share in that payment if there's more than one perfect bracket submitted. Free registration for the contest will begin March 3 and run until March 19.
