Pension Funding Index, June 2011
07 June 2011
The funded status of the 100 largest corporate defined benefit pension plans worsened by $26 billion during May 2011, as measured by the Milliman 100 Pension Funding Index (PFI). May's funded status erosion was due primarily to a decrease in corporate bond interest rates, the benchmarks used to value pension liabilities. The funded ratio fell to 85.6%, down from 87.2% at the end of April, increasing the funded status deficit to $210 billion.
