SALEM, Ore. (AP) — Some retired state workers who helped pay for a successful class-action lawsuit against the Oregon Public Employees Retirement System five years ago are entitled to some money back — up to 72 cents for each dollar they gave.

But it has been hard to find some of the original contributors to the fund, which still has $243,000 on hand.

The refund goes to workers who contributed to the Oregon Public Retirees Litigation Fund between July 1, 2003, and October 21, 2005.

The group that managed the legal fund, Oregon PERS Retirees, says that some contributors have told the group to keep the money for future lawsuits.

But other people probably don't know the money is available. The group asks anybody who contributed to the class-action lawsuit, known as the Sartain (sahr-TAYN) case, to apply for the refund.
