The 11th annual Milliman Pension Funding Study is now available. In 2011, the 100 corporate pensions measured by this study saw a slight improvement in funded status. While assets performed well in 2010--a 12.8% return and a $115 billion improvement--they were counteracted by a liability increase of 7.7% (resulting in a $103 increase in the projected benefit obligation). These competing dynamics are illustrated in the plan asset and liability graph.
