Royal & SunAlliance is adding a FTSE All Share Tracker Pension Fund to it range of funds.
The fund will passively track the FTSE All Share using a computer model which enable the costs of the fund to be kept to a minimum.
Dealing only occurs when there are changes to the Index or when units are created or liquidated this further assists in keeping the funds cost low.
RSA's pensions marketing manager Mark Birks says: "The imminent arrival of stakeholder pensions is putting an increasing emphasis on low fund management charges. The increasing use of tracker funds is a prime example of this."
