The PPF index calculates the total assets minus liabilities of around 7,400 DB funds in the UK.
In March 2009, the total surpluses of schemes in surplus fell to £11bn from £13bn at the end of February 2009.
In March 2008, the total surplus of all schemes in surplus stood at £59bn.
Punter Southall principal David Cule says: “Today’s news from the PPF 7800 Index shows that in current conditions UK companies are required to provide at least £240bn of support for UK pension schemes – more if benefits are expected to be provided in full.
“This is significantly greater than the quantitative easing package put together and on a par with the level of support being put together for the UK banking system.”
