The US government will now use made-up prices to fix old retirement fund errors

The US government changed how it fixes mistakes in old retirement funds that no longer exist. It will now use a calculated share price to determine how much money is owed or needs to be returned.

When a retirement fund closes, its actual share price disappears. This makes it hard to correct errors that happened years ago. This rule means the government can still fix those old mistakes, even without real market data. It ensures that people who had money in those funds are made whole, or that overpayments are recovered, regardless of how long ago the fund closed.
