(a)Benefit obligation balances represent the projected benefit obligation for our qualified defined benefit pension plans and the accumulated benefit obligation for our retiree medical and life insurance plans. (b)Actuarial gains for our qualified defined benefit pension plans in 2022 primarily reflect an increase in the discount rate from 2.875% at December 31, 2021 to 5.25% at December 31, 2022, which decreased benefit obligations by $10.2 billion. Actuarial gains for our retiree medical and life insurance plans in 2022 reflect an increase in the discount rate from 2.750% at December 31, 2021 to 5.25% at December 31, 2022, which decreased benefit obligations by $335 million. Actuarial gains for our qualified defined benefit pension plans in 2021 primarily reflect an increase in the discount rate from 2.50% at December 31, 2020 to 2.875% at December 31, 2021, which decreased benefit obligations by $2.3 billion, partially offset by an increase of approximately $250 million due to changes in longevity assumptions and participant data. Actuarial gains for our retiree medical and life insurance plans in 2021 reflect an increase in the discount rate from 2.375% at December 31, 2020 to 2.75% at December 31, 2021, which decreased benefit obligations by $70 million, and $282 million due to changes in plan participation assumptions and claims data. (c)Qualified defined benefit pension plan settlements in 2022 and 2021 represent the transfer of gross defined benefit pension obligations and related plan assets to insurance companies pursuant to group annuity contracts purchased in the second quarter of 2022 and third quarter of 2021 as described above. (d)Actual return on plan assets for our qualified defined benefit pension plans and retiree medical and life insurance plans was approximately (18)% in 2022 and 10.5% in 2021.

(a)A pension discount rate of 4.75%, and 2.75%, was used for the applicable plans following the transaction and remeasurement recognized in the second quarter of 2022, and third quarter of 2021, respectively. We lowered our expected long-term rate of return on plan assets from 7.00% to 6.50% in connection with the third quarter of 2021 remeasurement, applicable to all qualified defined benefit pension and retiree medical and life insurance plans as of the December 31, 2021 remeasurement.
Schedule of Allocation of Plan Assets | LMIMCo’s investment policies require that asset allocations of postretirement benefit plans be maintained within the following approximate ranges:
Asset Class | Asset Allocation Ranges
Cash and cash equivalents | 0-20%
Global Equity | 15-65%
Fixed income | 10-60%
Alternative investments: |
Private equity funds | 5-25%
Real estate funds | 5-15%
Hedge funds | 0-20%
Commodities | 0-10%
The following table presents the fair value of the assets 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 (see “Note 1 – Organization and Significant Accounting Policies - Investments” for definition of these levels), which we are required to disclose even though these assets are not separately recorded on our consolidated balance sheet. Certain investments are measured at their Net Asset Value (NAV) per share because such investments do not have readily determinable fair values and, therefore, are not required to be categorized in the fair value hierarchy. Assets measured at NAV have been included in the table below to permit reconciliation of the fair value hierarchy to amounts presented in the funded status table above.

(a)Cash and cash equivalents, equity securities and fixed income securities included derivative assets and liabilities with fair values that were not material as of December 31, 2022 and 2021. LMIMCo’s investment policies restrict the use of derivatives to either establish long or short exposures for purposes consistent with applicable investment mandate guidelines 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)Level 3 investments include $1.1 billion at December 31, 2022 and $1.5 billion at December 31, 2021 related to buy-in contracts. (c)The Lockheed Martin Corporation Master Retirement Trust (MRT) obtained a loan from a third party financial institution, collateralized by private equity investments, to invest in fixed income securities.
