| (a) |
Benefits paid in 2012 for qualified defined benefit pension plans include $310 million in the form of lump-sum settlement payments to former employees who had not commenced receiving their vested benefit payments. The corresponding benefit obligation that was released was $375 million. The settlement payments had no impact on our 2012 FAS pension expense and CAS pension cost. |
