It further stated that the current practice, whereby each scheme purchases an annuity for its members, which is then topped up by the government, is not necessarily the best use of these assets.
"The government believes that the cost of extending the FAS towards 90 per cent can now be met by making better use of the assets remaining in pension schemes, matched by a further contribution from government," Mr O'Brien said.
"We will need the cooperation of every pension scheme to get there.
"We are committing today to match the extra funds that the review identifies with a goal of moving towards 90 per cent of expected core pension for all recipients.
"Those extra funds will be based on the amount of assets remaining in schemes. Trustees must continue to act in their members' best interests, but we hope they will now take the view that those interests may not be served by expending scheme assets on annuities."
The government recently defeated amendments to a bill that would have forced it to do more to help out people who have lost pension funds.
