Pension Funding Index, May 2011
10 May 2011
The funded status of the 100 largest corporate defined benefit pension plans dropped by $12 billion during April 2011, as measured by the Milliman 100 Pension Funding Index (PFI). The funded status deficit increased to $184 billion from $172 billion at the end of March, primarily due to a $31 billion liability increase that resulted from a reduction in the discount rate. There were offsetting investment gains on plan assets of $19 billion.
