New state numbers confirm that Illinois has the worst-funded pension systems of all 50 states. The state’s pension system currently has just 41.9% of its liability covered. A state legislative report says Illinois added $6.4 billion to its shortfall in fiscal 2015, for a total of $111 billion. The report says the unfunded liability will rise to nearly $115 billion in the current fiscal year. The report also believes the number could rise to as high as $132 billion by 2029.
