Availability payment concessions replace ridership risk transfer
Minimum revenue guarantee structures asked private operators to carry demand risk on forecasts that turned out to be wrong by around 47% in the Korean cases, and the municipalities carrying the guarantee absorbed liabilities that broke several budgets. Availability payments move the compensation basis to whether the system runs rather than to how many people use it, which reflects what an operator can actually control. Every recent concession has moved that way. The commercial consequence for suppliers is significant: bidding against availability rather than ridership changes the risk premium and makes long operations agreements considerably more financeable.
