1: Total net periodic benefit cost associated with our qualified defined benefit plans represents pension expense calculated in accordance with GAAP (FAS expense). We are required to calculate pension expense in accordance with both GAAP and CAS rules, each of which results in a different calculated amount of pension expense. The CAS cost is recovered through the pricing of our products and services on U.S. Government contracts and, therefore, is recognized in net sales and cost of sales for products and services. We include the difference between FAS expense and CAS cost, referred to as the FAS/CAS pension adjustment, as a component of other unallocated costs on our Statements of Earnings. The FAS/CAS pension adjustment, which was expense of $482 million in 2013, $830 million in 2012, and $922 million in 2011, effectively adjusts the amount of CAS pension cost in the business segment operating profit so that pension expense recorded on our Statements of Earnings is equal to FAS expense.
2: 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.
