Britain's leading companies have wiped out the multi-billion pound deficit in their pension schemes, according to accountancy firm Deloitte.
Top firms have taken action over their pension schemes' deficit
The country's top 100 share index companies' pensions now have a combined surplus of £15bn, the firm said.
Two years ago the collective black hole in the pension schemes of the top 100 firms was an estimated £75bn.
But analysts urged caution, saying a bad run on the stock market could turn the surplus back into a deficit.
The deep deficit of two years ago spurred firms to take action to safeguard their pension schemes.
Their newly robust health is a result of injections of cash, restructuring the schemes and a strong stock market.
