January 7, 2013 (PLANSPONSOR.com) - In December, plans in the Milliman 100 Pension Funding Index experienced a $54 billion increase in funded status.
The increase is due to a $46 billion decrease in the pension benefit obligation (PBO) and an $8 billion increase in assets.
The $54 billion improvement in December follows a $33 billion improvement in November, but it would still take many more months of improvement to make up for a year of ballooning pension deficit, Milliman said. At year end, the deficit of $412 billion is $74 billion higher than last year.
"It was a good year on the asset side, with these pensions experiencing a $90 billion gain," said John Ehrhardt, co-author of the Milliman Pension Funding Study. "But it was a rough year on the liability side, with interest rates driving a $164 billion increase in the pension benefit obligation. People may be getting tired of hearing me saying it but interest rates have been the story for the last four years and that's not going to change in 2013."
In December, the discount rate used to calculate pension liabilities increased from 4.05% to 4.18%, decreasing the PBO from $1.794 trillion to $1.748 trillion at the end of the month. The overall asset value for these 100 pensions increased from $1.328 trillion to $1.336 trillion.
Looking forward, if these 100 pensions were to achieve their expected 7.8% median asset return and if the current discount rate of 4.18% were to be maintained throughout 2013 and 2014, these pensions would improve the pension funded ratio from 76.4% to 81.0% by the end of 2013 and to 85.7% by the end of 2014.
