Schedule Of Net Periodic Benefit Costs | The net periodic benefit cost recognized each year included the following (in millions):
|  | Qualified Defined Benefit Pension Plans (a) |  |  |  |  |  |  |  |  | Retiree Medical and Life Insurance Plans |
|  | 2016 |  |  | 2015 |  |  | 2014 |  |  |  |  |  |  |  |  | 2016 |  |  | 2015 |  |  | 2014 |

Expected return on plan assets |  |  | (2,666) |  |  |  | (2,734) |  |  |  | (2,693) |  |  |  |  |  |  |  |  |  |  |  | (138) |  |  |  | (147) |  |  |  | (146) |
Recognized net actuarial losses |  |  | 1,359 |  |  |  | 1,599 |  |  |  | 1,173 |  |  |  |  |  |  |  |  |  |  |  | 34 |  |  |  | 43 |  |  |  | 23 |
Amortization of net prior service (credit) cost (b) |  |  | (362) |  |  |  | (365) |  |  |  | (134) |  |  |  |  |  |  |  |  |  |  |  | 22 |  |  |  | 4 |  |  |  | 4 |
Total net periodic benefit cost |  | $ | 1,019 |  |  | $ | 1,127 |  |  | $ | 1,099 |  |  |  |  |  |  |  |  |  |  | $ | 61 |  |  | $ | 31 |  |  | $ | 26 |
(a) | Total net periodic benefit cost associated with our qualified defined benefit plans represents pension expense calculated in accordance with GAAP (FAS pension 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 pension 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 pension expense and CAS pension cost, referred to as the FAS/CAS pension adjustment, as a component of other unallocated, net on our consolidated statements of earnings. The FAS/CAS pension adjustment, which was $902 million in 2016, $400 million in 2015, and $317 million in 2014, effectively adjusts the amount of CAS pension cost in the business segment operating profit so that pension expense recorded on our consolidated statements of earnings is equal to FAS pension expense. FAS pension expense and CAS pension costs reflect the reclassification for discontinued operations presentation of benefits related to former IS&GS salaried employees.
(b) | Net of the reclassification for discontinued operations presentation of pension benefits related to former IS&GS salaried employees ($14 million in 2016, $24 million in 2015 and $17 million in 2014).

Actuarial Assumptions Used to Determine Net Periodic Benefit Cost | The actuarial assumptions used to determine the benefit obligations at December 31 of each year and to determine the net periodic benefit cost for each subsequent year, were as follows:
|  | Qualified Defined Benefit Pension Plans |  |  |  |  |  |  |  |  | Retiree Medical and Life Insurance Plans |
|  | 2016 |  |  | 2015 |  |  | 2014 |  |  |  |  |  |  |  |  | 2016 |  |  | 2015 |  |  | 2014 |

Expected long-term rate of return on assets |  |  | 7.50% |  |  |  | 8.00% |  |  |  | 8.00% |  |  |  |  |  |  |  |  |  |  |  | 7.50% |  |  |  | 8.00% |  |  |  | 8.00% |

Schedule of Allocation of Plan Assets | Fair value measurements – The rules related to accounting for postretirement benefit plans under GAAP require certain fair value disclosures related to postretirement benefit plan assets, even though those assets are not included on our consolidated balance sheets. The following table presents the fair value of the assets (in millions) of our qualified defined benefit pension plans and retiree medical and life insurance plans by asset category and their level within the fair value hierarchy, which has three levels based on the reliability of the inputs used to determine fair value. Level 1 refers to fair values determined based on quoted prices in active markets for identical assets, Level 2 refers to fair values estimated using significant other observable inputs and Level 3 includes fair values estimated using significant unobservable inputs. Certain other investments are measured at fair value using their Net Asset Value (NAV) per share and do not have readily determined values and are thus not subject to leveling in the fair value hierarchy. The NAV is the total value of the fund divided by the number of shares outstanding.

(a) | Cash and cash equivalents, equity securities, fixed income securities and commodities included derivative assets and liabilities whose fair values were not material as of December 31, 2016 and 2015. LMIMCo’s investment policies restrict the use of derivatives to either establish long exposures for purposes of expediency or capital efficiency or to hedge risks to the extent of a plan’s current exposure to such risks. Most derivative transactions are settled on a daily basis.
(b) | Certain investments that are valued using the net asset value per share (or its equivalent) as a practical expedient have not been classified in the fair value hierarchy and are included in the table to permit reconciliation of the fair value hierarchy to the aggregate postretirement benefit plan assets.
Changes In Fair Value of Level 3 Plan Assets | The following table presents the changes during 2016 and 2015 in the fair value of plan assets categorized as Level 3 in the preceding table (in millions):
