That pension system is nuts btw.

These savings would be achieved by smoothing out a bizarre feature of the city’s pension payment schedule instituted in 2010, which had required accelerating payments through to fiscal year 2032, at which point the payments would turn negative and the pension funds would return money to the City over a seven-year period. The $8.2 billion “contribution cliff” created by this structure was not reasonable fiscal policymaking. The proposed change unwinds this drop off by smoothing payments over an additional five years. It does not—and cannot—affect the pensions owed to City workers or impact the City’s ability to meet those commitments.
