"The Treasury Department ... [has] named Kenneth R. Feinberg to oversee a new program to allow certain pension plans to cut retirees' benefits if that is the only way to keep them from running out of money.... Mr. Feinberg said he was accepting the appointment on a pro bono basis.... Mr. Feinberg previously served as a special master for the Troubled Asset Relief Program, sorting out disputes over whether bailed-out financial institutions were improperly rewarding their executives with taxpayer dollars. He also oversaw compensation programs for people harmed by the Deepwater Horizon oil spill, the Boston Marathon bombings and the 2001 terrorist attacks."
