Pension schemes for FTSE 100-listed companies failed to benefit from a rising stock market in the past year, leaving them with a gap between assets and liabilities of some £43 billion pounds ($66.09 billion), according to a new report released on Tuesday.

The pension funds have upped their equity exposure over the last year but this has not helped fill the funding hole, which is £1 billion larger than it was a year ago, research from financial consultancy firm Lane Clark & Peacock (LCP) showed. The funds plunged into deficit in 2008, going from a £12 billion surplus in 2007 to a £41 billion deficit a year later.
