Ohio-based U.S. Senator, Sherrod Brown alongside Indiana-based U.S. Senator Mike Braun led the introduction of bipartisan legislation dubbed the Susan Muffley Act to restore the retirement benefits of over 20,000 Delphi Salaried Retirees on Wednesday.

When General Motors filed for bankruptcy during the Great Recession, the U.S. Pension Benefit Guarantee Corporation (PBGC) assumed responsibility for the terminated benefits, but could not pay an individual more than a statutory maximum beneift.

As such, retirees experienced significant losses to their benefits affecting 20,000 salaried retirees including more than 5,000 retirees in Ohio and 4,000 in Indiana.

If passed, The Susan Muffley Act would restore these terminated pensions, making up the difference between the benefits earned by the retirees and what they received following GM's bankruptcy in 2009.

This means beneficiaries who have already begun receiving benefits will receive a lump sum payment of the difference between what was actually paid by the PBGC and what would have been paid without the limitations plus interest.

Retirees may pay income taxes on this lump sum over three years to ease the tax burdens.

Numerous other senators will introduce the legislation in the Senate including Pennsylvania's Bob Casey and John Fetterman. Representative Mike Turner introduced the legislation in the House of Representatives.
