About a billion dollars of Sears pension funds were 'de-risked' last year by buying annuities from MetLife. That will fully fund 71,000 retirees, with no Sears stock involved anymore.

However, that still leaves a lot of the pension fund in stocks, apparently still including Sears stock. :-( There were two lawsuits filed about this last year (ERISA violation for continuing to hold such a risky stock), but it may take years for them to work their way through the court system.
