Impact of unfunded pension obligations on credit quality of state governments

This study reviews the funding status of state-administered pension plans and their impact on state credit quality. As the fund ratio (actuarial assets/actuarial accrued liability) of state-administered pension plans decreases, states are more likely assigned a lower rating. Moreover, rating outlooks are sensitive to the fund ratio, especially for migration between stable and negative outlooks for states with lower fund ratios. These results are a timely pretest to the 2013/2014 implementation of GASB Statements No. 67 and 68, serving as a benchmark to assess whether new reporting requirements will yield information to alter the market's response to unfunded pension liabilities.
