UK - Standard Life has agreed to compensate around 97,000 customers who lost out when its Pension Sterling Fund fell by 4.8% last month.
It said the move would result in an additional approximate pre-tax charge of £100m (US$143.9m) against profits in 2008.
Standard Life said it made the decision because many people "were not fully aware of the nature of the fund" and that some customers could not have anticipated the value of their units could fall so drastically in one day.
Managing director of customer service John Gill said: "Standard Life would like to take this opportunity to apologise to any customers who have been affected by the fall in value of this fund. In hindsight, some of the literature supporting the fund fell short of our own high standards, and it is important that we put this right.
"We have listened to our customers and advisers and believe that our response underlines our commitment to our long-term relationship with them."
The Standard Life Pension Sterling Fund invests in bank and building society deposits and floating rate notes - the majority of which are asset backed securities.
Sacker & Partners partner Katherine Dandy said a number of schemes have asked the firm to review the situation because "the trustees have had complaints from members".
She said: "We have not formed any final views at the moment because all these schemes are different."
Dandy also stressed the firm's role was "very much at a preliminary stage".
