Senior finance executives at UK companies are less confident than their US and Canadian counterparts in accessing cash to fund retirement commitments over the next two years, according to research by Towers Perrin. The research of 439 senior finance executives from large US, UK and Canadian firms in response to economic turmoil found that 61 per cent of Canadian senior finance executives are certain they have adequate access to cash to fund retirement commitments, followed by the US with 47 per cent and the UK with less than a third. In the UK 35 per cent of senior finance executives said they either might not be able to or couldn\'t finance their pension scheme over the next two years. John Manion, principal and director of Towers Perrin Capital Markets, says: \"It\'s a case of many companies having to go back to trustees to tell them they will have to wait for the money. DB pension funding is at a level where more than two thirds of senior finance executives are currently or will have to renegotiate arrangements with trustees to support the pension scheme.\"
