In the US, the aggregate deficit of S&P 1500 companies grew $59 billion (£38bn) in the first half of the year to $543bn, consultancy Mercer said.
Corporate America is sitting on total liabilities of $2.09 trillion against total assets of $1.55tn, Mercer added.
The picture is no less bleak in Britain, where the combined deficit of FTSE 100 companies more than doubled over the past year to £41bns, actuarial firm Lane, Clark & Peacock (LCP) said in a separate report yesterday. This is despite companies having poured £11bn into schemes over the last year.
