"All told, Ferrovial’s cash investment, debt and other costs are estimated at $378 million over the life of the contract. Excluding interest on borrowing, DIA would shoulder a commitment as high as $1.8 billion — including covering 74 percent of the $650 million renovation cost, providing a $120 million contingency fund, and then paying annual capital and operational payments to the Ferrovial team that over 30 years will total $1.2 billion."

This looks and sounds totally nuts.
