The unfunded pension liability of Kentucky’s state and local governments grew by more than $5 billion last year, adding urgency to the pension crisis that threatens to derail every other public service. As of June 30, Kentucky Retirement Systems had $26.75 billion more in future pension liabilities than it held in anticipated assets. That was up from $21.17 billion on the same day in 2016, according to data presented Monday to the KRS Board of Trustees.
