This document summarizes the state of US state pension plans. It notes that while unfunded pension liabilities grew significantly after the recession, recent reforms and market gains are expected to gradually reduce the burden over the next few years. As of 2012, unfunded liabilities totaled over $1 trillion when including local governments. States have implemented reforms like reduced benefits, shifting to defined contribution plans, and hybrid plans to address shortfalls. Increasing disclosure requirements are also expected to bring more attention to the issue and encourage further reforms.
