Minnesota is facing a $16.7-billion shortfall when it comes to funding public pensions. Despite legislation approved more than two years ago intended to boost retirement plans, the funding shortfall has increased by more than $4-billion since 2010. Overall, pensions for current and retired state workers are being funded at a 75% level. Plans for state troopers, public safety workers, and local police and firefighters are among those with the largest gap. Lawmakers will consider changes to those plans this year. The plans pay for retirement for more than 729,000 current and retired state and local government workers.
