Employee Benefit Plans | Employee Benefit Plans Defined Benefit Plans Domestic Operations PacifiCorp, MidAmerican Energy and NV Energy sponsor defined benefit pension plans that cover a majority of all employees of BHE and its domestic energy subsidiaries. These pension plans include noncontributory defined benefit pension plans, supplemental executive retirement plans ("SERP") and restoration plans. PacifiCorp, MidAmerican Energy and NV Energy also provide certain postretirement healthcare and life insurance benefits through various plans to eligible retirees. Net Periodic Benefit Cost For purposes of calculating the expected return on plan assets, a market-related value is used. The market-related value of plan assets is generally calculated by spreading the difference between expected and actual investment returns over a five-year period beginning after the first year in which they occur. Net periodic benefit cost (credit) for the plans included the following components for the years ended December 31 (in millions):
Funded Status The following table is a reconciliation of the fair value of plan assets for the years ended December 31 (in millions):
The following table is a reconciliation of the benefit obligations for the years ended December 31 (in millions):
The funded status of the plans and the amounts recognized on the Consolidated Balance Sheets as of December 31 are as follows (in millions):
The SERPs and restoration plan have no plan assets; however, the Company has Rabbi trusts that hold corporate-owned life insurance and other investments to provide funding for the future cash requirements of the SERPs and restoration plan. The cash surrender value of all of the policies included in the Rabbi trusts, net of amounts borrowed against the cash surrender value, plus the fair market value of other Rabbi trust investments, was $300 million and $343 million as of December 31, 2022 and 2021, respectively. These assets are not included in the plan assets in the above table, but are reflected in noncurrent investments and restricted cash and investments on the Consolidated Balance Sheets. The fair value of plan assets, projected benefit obligation and accumulated benefit obligation for (1) pension and other postretirement benefit plans with a projected benefit obligation in excess of the fair value of plan assets and (2) pension plans with an accumulated benefit obligation in excess of the fair value of plan assets as of December 31 are as follows (in millions):
Unrecognized Amounts The portion of the funded status of the plans not yet recognized in net periodic benefit cost as of December 31 is as follows (in millions):
A reconciliation of the amounts not yet recognized as components of net periodic benefit cost for the years ended December 31, 2022 and 2021 is as follows (in millions):
Plan Assumptions Weighted-average assumptions used to determine benefit obligations and net periodic benefit cost were as follows:
In establishing its assumption as to the expected return on plan assets, the Company utilizes the asset allocation and return assumptions for each asset class based on historical performance and forward-looking views of the financial markets.
Contributions and Benefit Payments Employer contributions to the pension and other postretirement benefit plans are expected to be $13 million and $7 million, respectively, during 2023. Funding to the established pension trusts is based upon the actuarially determined costs of the plans and the requirements of the IRC, the Employee Retirement Income Security Act of 1974 and the Pension Protection Act of 2006, as amended. The Company considers contributing additional amounts from time to time in order to achieve certain funding levels specified under the Pension Protection Act of 2006, as amended. The Company evaluates a variety of factors, including funded status, income tax laws and regulatory requirements, in determining contributions to its other postretirement benefit plans. The expected benefit payments to participants in the Company's pension and other postretirement benefit plans for 2023 through 2027 and for the five years thereafter are summarized below (in millions):
Plan Assets Investment Policy and Asset Allocations The Company's investment policy for its pension and other postretirement benefit plans is to balance risk and return through a diversified portfolio of debt securities, equity securities and other alternative investments. Maturities for debt securities are managed to targets consistent with prudent risk tolerances. The plans retain outside investment consultants to advise on plan investments within the parameters outlined by the Berkshire Hathaway Energy Company Investment Committee. The investment portfolio is managed in line with the investment policy with sufficient liquidity to meet near-term benefit payments. The target allocations (percentage of plan assets) for the Company's pension and other postretirement benefit plan assets are as follows as of December 31, 2022:
(1)For purposes of target allocation percentages and consistent with the plans' investment policy, investment funds are allocated based on the underlying investments in debt and equity securities. Fair Value Measurements The following table presents the fair value of plan assets, by major category, for the Company's defined benefit pension plans (in millions):
(1)Refer to Note 15 for additional discussion regarding the three levels of the fair value hierarchy. (2)Investment funds are comprised of mutual funds and collective trust funds. These funds consist of equity and debt securities of approximately 53% and 47%, respectively, for 2022 and 54% and 46%, respectively, for 2021. Additionally, these funds are invested in U.S. and international securities of approximately 95% and 5%, respectively, for 2022 and 89% and 11%, respectively, for 2021. (3)Limited partnership interests include several funds that invest primarily in real estate, buyout, growth equity and venture capital. The following table presents the fair value of plan assets, by major category, for the Company's defined benefit other postretirement plans (in millions):
(1)Refer to Note 15 for additional discussion regarding the three levels of the fair value hierarchy. (2)Investment funds are comprised of mutual funds and collective trust funds. These funds consist of equity and debt securities of approximately 55% and 45%, respectively, for 2022 and 55% and 45%, respectively, for 2021. Additionally, these funds are invested in U.S. and international securities of approximately 88% and 12%, respectively, for 2022 and 88% and 12%, respectively, for 2021. (3)Limited partnership interests include several funds that invest primarily in real estate, buyout, growth equity and venture capital. For level 1 investments, a readily observable quoted market price or net asset value of an identical security in an active market is used to record the fair value. For level 2 investments, the fair value is determined using pricing models based on observable market inputs. Shares of mutual funds not registered under the Securities Act of 1933, private equity limited partnership interests, common and commingled trust funds and investment entities are reported at fair value based on the net asset value per unit, which is used for expedience purposes. A fund's net asset value is based on the fair value of the underlying assets held by the fund less its liabilities. Foreign Operations Certain wholly-owned subsidiaries of Northern Powergrid participate in the Northern Powergrid group of the United Kingdom industry-wide Electricity Supply Pension Scheme (the "UK Plan"), which provides pension and other related defined benefits, based on final pensionable pay, to the employees of Northern Powergrid. The UK Plan is closed to employees hired after July 23, 1997. Employees hired after that date are covered by a defined contribution plan sponsored by a wholly-owned subsidiary of Northern Powergrid. Net Periodic Benefit Cost For purposes of calculating the expected return on pension plan assets, a market-related value is used. The market-related value of plan assets is calculated by including the difference between expected and actual investment returns after the first year in which they occur. Net periodic benefit (credit) cost for the UK Plan included the following components for the years ended December 31 (in millions):
Funded Status The following table is a reconciliation of the fair value of plan assets for the years ended December 31 (in millions):
The following table is a reconciliation of the benefit obligation for the years ended December 31 (in millions):
The funded status of the UK Plan and the amounts recognized on the Consolidated Balance Sheets as of December 31 are as follows (in millions):
Unrecognized Amounts The portion of the funded status of the UK Plan not yet recognized in net periodic benefit cost as of December 31 is as follows (in millions):
A reconciliation of the amounts not yet recognized as components of net periodic benefit cost, which are included in accumulated other comprehensive loss on the Consolidated Balance Sheets, for the years ended December 31 is as follows (in millions):
Plan Assumptions Assumptions used to determine benefit obligations and net periodic benefit cost were as follows:
Contributions and Benefit Payments Employer contributions to the UK Plan are expected to be £11 million during 2023. The expected benefit payments to participants in the UK Plan for 2023 through 2027 and for the five years thereafter, excluding lump sum settlement elections and using the foreign currency exchange rate as of December 31, 2022, are summarized below (in millions):
Plan Assets Investment Policy and Asset Allocations The investment policy for the UK Plan is to balance risk and return through a diversified portfolio of debt securities, equity securities, real estate and other asset classes. Maturities for debt securities are managed to targets consistent with prudent risk tolerances. The UK Plan retains outside investment advisors to manage plan investments within the parameters set by the trustees of the UK Plan in consultation with Northern Powergrid. The investment portfolio is managed in line with the investment policy with sufficient liquidity to meet near-term benefit payments. The return on assets assumption is based on a weighted-average of the expected historical performance for the types of assets in which the UK Plan invests. The target allocations (percentage of plan assets) for the UK Plan assets are as follows as of December 31, 2022:
(1)For purposes of target allocation percentages and consistent with the plans' investment policy, investment funds have been allocated based on the underlying investments in debt and equity securities. Fair Value Measurements The following table presents the fair value of the UK Plan assets, by major category (in millions):
(1)Refer to Note 15 for additional discussion regarding the three levels of the fair value hierarchy. (2)Investment funds are comprised of mutual funds and collective trust funds. These funds consist of equity and debt securities of approximately 25% and 75%, respectively, for 2022 and 23% and 77%, respectively, for 2021. The fair value of the UK Plan's assets are determined similar to the plan assets of the domestic plans as previously discussed. The following table reconciles the beginning and ending balances of the UK Plan assets measured at fair value using significant Level 3 inputs for the years ended December 31 (in millions):
Defined Contribution Plans The Company sponsors various defined contribution plans covering substantially all employees. The Company's contributions vary depending on the plan, but matching contributions are based on each participant's level of contribution, and certain participants receive contributions based on eligible pre-tax annual compensation. Contributions cannot exceed the maximum allowable for tax purposes. The Company's contributions to these plans were $159 million, $137 million and $127 million for the years ended December 31, 2022, 2021 and 2020, respectively.

Employee Benefit Plans | Employee Benefit Plans PacifiCorp sponsors defined benefit pension and other postretirement benefit plans that cover certain of its employees, as well as a defined contribution 401(k) employee savings plan ("401(k) Plan"). In addition, PacifiCorp contributes to a joint trustee pension plan and a subsidiary previously contributed to a multiemployer pension plan for benefits offered to certain bargaining units. Defined Benefit Plans PacifiCorp's pension plans include non-contributory defined benefit pension plans, collectively the PacifiCorp Retirement Plan ("Retirement Plan"), and the Supplemental Executive Retirement Plan ("SERP"). The Retirement Plan is closed to all non-union employees hired after January 1, 2008. All non-union Retirement Plan participants hired prior to January 1, 2008 that did not elect to receive equivalent fixed contributions to the 401(k) Plan effective January 1, 2009 earned benefits based on a cash balance formula through December 31, 2016. Effective January 1, 2017, non-union employee participants with a cash balance benefit in the Retirement Plan are no longer eligible to receive pay credits in their cash balance formula. In general for union employees, benefits under the Retirement Plan were frozen at various dates from December 31, 2007 through December 31, 2011 as they are now being provided with enhanced 401(k) Plan benefits. However, certain limited union Retirement Plan participants continue to earn benefits under the Retirement Plan based on the employee's years of service and a final average pay formula. The SERP was closed to new participants as of March 21, 2006 and froze future accruals for active participants as of December 31, 2014. PacifiCorp's other postretirement benefit plan provides healthcare and life insurance benefits to eligible retirees. Pension Settlement Pension settlement accounting was triggered in 2022 and 2021 as a result of the amount of lump sum distributions in the Retirement Plan exceeding the service and interest cost threshold. The 2021 pension settlement accounting included an interim July 31, 2021 remeasurement of the pension plan assets and projected benefit obligation. As a result of the settlement accounting, PacifiCorp recognized settlement losses of $6 million, net of regulatory deferrals during each of the years ended December 31, 2022 and 2021. Net Periodic Benefit Cost For purposes of calculating the expected return on plan assets, a market-related value is used. The market-related value of plan assets is calculated by spreading the difference between expected and actual investment returns over a five-year period beginning after the first year in which they occur. Net periodic benefit cost (credit) for the plans included the following components for the years ended December 31 (in millions):
(1)Pension amounts represent settlement losses of $24 million and $15 million net of deferrals of $18 million and $9 million during the years ended December 31, 2022 and 2021. Funded Status The following table is a reconciliation of the fair value of plan assets for the years ended December 31 (in millions):
(1)Pension amounts represent employer contributions to the SERP. (2)Benefits paid in the form of lump sum distributions that gave rise to the settlement accounting described above. The following table is a reconciliation of the benefit obligations for the years ended December 31 (in millions):
(1)Benefits paid in the form of lump sum distributions that gave rise to the settlement accounting described above. The funded status of the plans and the amounts recognized on the Consolidated Balance Sheets as of December 31 are as follows (in millions):
The SERP has no plan assets; however, PacifiCorp has a Rabbi trust that holds corporate-owned life insurance and other investments to provide funding for the future cash requirements of the SERP. The cash surrender value of all of the policies included in the Rabbi trust, net of amounts borrowed against the cash surrender value, plus the fair market value of other Rabbi trust investments, was $61 million and $69 million as of December 31, 2022 and 2021, respectively. These assets are not included in the plan assets in the above table, but are reflected in noncurrent other assets as of December 31, 2022 and 2021, respectively, on the Consolidated Balance Sheets. The projected and accumulated benefit obligations for the SERP were $42 million and $54 million at December 31, 2022 and 2021, respectively. As of December 31, 2022, the fair value of the plan assets for the Retirement Plan was in excess of both the projected benefit obligation and the accumulated benefit obligation. Unrecognized Amounts The portion of the funded status of the plans not yet recognized in net periodic benefit cost as of December 31 is as follows (in millions):
(1)Pension amounts represent the unamortized portion of deferred settlement losses. A reconciliation of the amounts not yet recognized as components of net periodic benefit cost for the years ended December 31, 2022 and 2021 is as follows (in millions):
Plan Assumptions Assumptions used to determine benefit obligations and net periodic benefit cost were as follows:
In establishing its assumption as to the expected return on plan assets, PacifiCorp utilizes the asset allocation and return assumptions for each asset class based on historical performance and forward-looking views of the financial markets. As a result of a plan amendment effective on January 1, 2017, the benefit obligation for the Retirement Plan is no longer affected by future increases in compensation. As a result of a labor settlement reached with UMWA in December 2014, the benefit obligation for the other postretirement plan is no longer affected by healthcare cost trends. Contributions and Benefit Payments Employer contributions to the pension and other postretirement benefit plans are expected to be $4 million and $— million, respectively, during 2023. Funding to PacifiCorp's Retirement Plan trust is based upon the actuarially determined costs of the plan and the requirements of the Internal Revenue Code, the Employee Retirement Income Security Act of 1974 ("ERISA") and the Pension Protection Act of 2006, as amended ("PPA of 2006"). PacifiCorp considers contributing additional amounts from time to time in order to achieve certain funding levels specified under the PPA of 2006. PacifiCorp evaluates a variety of factors, including funded status, income tax laws and regulatory requirements, in determining contributions to its other postretirement benefit plan. The expected benefit payments to participants in PacifiCorp's pension and other postretirement benefit plans for 2023 through 2027 and for the five years thereafter are summarized below (in millions):
Plan Assets Investment Policy and Asset Allocations PacifiCorp's investment policy for its pension and other postretirement benefit plans is to balance risk and return through a diversified portfolio of debt securities, equity securities and other alternative investments. Maturities for debt securities are managed to targets consistent with prudent risk tolerances. The plans retain outside investment consultants to advise on plan investments within the parameters outlined by the Berkshire Hathaway Energy Company Investment Committee. The investment portfolio is managed in line with the investment policy with sufficient liquidity to meet near-term benefit payments. In 2020, the assets of the PacifiCorp Master Retirement Trust were transferred into the BHE Master Retirement Trust. The target allocations (percentage of plan assets) for PacifiCorp's pension and other postretirement benefit plan assets are as follows as of December 31, 2022:
(1)The trust in which the PacifiCorp Retirement Plan is invested includes a separate account that is used to fund benefits for the other postretirement benefit plan. In addition to this separate account, the assets for the other postretirement benefit plan are held in Voluntary Employees' Beneficiary Association ("VEBA") trusts, each of which has its own investment allocation strategies. Target allocations for the other postretirement benefit plan include the separate account of the Retirement Plan trust and the VEBA trusts. (2)For purposes of target allocation percentages and consistent with the plans' investment policy, investment funds are allocated based on the underlying investments in debt and equity securities. Fair Value Measurements The following table presents the fair value of plan assets, by major category, for PacifiCorp's defined benefit pension plan (in millions):
(1)Refer to Note 13 for additional discussion regarding the three levels of the fair value hierarchy. (2)Investment funds are substantially comprised of mutual funds and collective trust funds. These funds consist of equity and debt securities of approximately 50% and 50%, respectively, for 2022 and 59% and 41%, respectively, for 2021, and are invested in U.S. and international securities of approximately 90% and 10%, respectively, for 2022 and 84% and 16%, respectively, for 2021. (3)Limited partnership interests include several funds that invest primarily in real estate. The following table presents the fair value of plan assets, by major category, for PacifiCorp's defined benefit other postretirement plan (in millions):
(1)Refer to Note 13 for additional discussion regarding the three levels of the fair value hierarchy. (2)Investment funds are substantially comprised of mutual funds and collective trust funds. These funds consist of equity and debt securities of approximately 41% and 59%, respectively, for 2022 and 39% and 61%, respectively, for 2021, and are invested in U.S. and international securities of approximately 91% and 9%, respectively, for 2022 and 90% and 10%, respectively, for 2021. (3)Limited partnership interests include several funds that invest primarily in real estate, buyout, growth equity and venture capital. For level 1 investments, a readily observable quoted market price or net asset value of an identical security in an active market is used to record the fair value. For level 2 investments, the fair value is determined using pricing models based on observable market inputs. Shares of mutual funds not registered under the Securities Act of 1933, private equity limited partnership interests, common and commingled trust funds and investment entities are reported at fair value based on the net asset value per unit, which is used for expedience purposes. A fund's net asset value is based on the fair value of the underlying assets held by the fund less its liabilities. Multiemployer and Joint Trustee Pension Plans PacifiCorp contributes to the PacifiCorp/IBEW Local 57 Retirement Trust Fund ("Local 57 Trust Fund") (plan number 001) and its subsidiary, Energy West Mining Company, previously contributed to the UMWA 1974 Pension Plan (plan number 002). Contributions to these pension plans are based on the terms of collective bargaining agreements. As a result of the Utah Mine Disposition and UMWA labor settlement, PacifiCorp's subsidiary, Energy West Mining Company, triggered involuntary withdrawal from the UMWA 1974 Pension Plan in June 2015 when the UMWA employees ceased performing work for the subsidiary. PacifiCorp recorded its estimate of the withdrawal obligation in December 2014 when withdrawal was considered probable and deferred the portion of the obligation considered probable of recovery to a regulatory asset. PacifiCorp has subsequently revised its estimate due to changes in facts and circumstances for a withdrawal occurring by July 2015. As communicated in a letter received in August 2016, the plan trustees determined a withdrawal liability of $115 million. Energy West Mining Company began making installment payments in November 2016 and has the option to elect a lump sum payment to settle the withdrawal obligation. The ultimate amount paid by Energy West Mining Company to settle the obligation is dependent on a variety of factors, including the results of ongoing negotiations with the plan trustees. The Local 57 Trust Fund is a joint trustee plan such that the board of trustees is represented by an equal number of trustees from PacifiCorp and the union. The Local 57 Trust Fund was established pursuant to the provisions of the Taft-Hartley Act and although formed with the ability for other employers to participate in the plan, there are no other employers that participate in this plan. The risk of participating in multiemployer pension plans generally differs from single-employer plans in that assets are pooled such that contributions by one employer may be used to provide benefits to employees of other participating employers and plan assets cannot revert to employers. If an employer ceases participation in the plan, the employer may be obligated to pay a withdrawal liability based on the participants' unfunded, vested benefits in the plan. This occurred as a result of Energy West Mining Company's withdrawal from the UMWA 1974 Pension Plan. If participating employers withdraw from a multiemployer plan, the unfunded obligations of the plan may be borne by the remaining participating employers. The following table presents PacifiCorp's participation in individually significant joint trustee and multiemployer pension plans for the years ended December 31 (dollars in millions):
PacifiCorp's minimum contributions to the Local 57 Trust Fund are based on the amount of wages paid to employees covered by the Local 57 Trust Fund collective bargaining agreements, subject to ERISA minimum funding requirements. The collective bargaining agreements governing the Local 57 Trust Fund that were due to expire in 2023 were extended to 2028 in December 2022. Defined Contribution Plan PacifiCorp's 401(k) Plan covers substantially all employees. PacifiCorp's matching contributions are based on each participant's level of contribution and, as of January 1, 2022, all participants receive contributions based on eligible pre-tax annual compensation. Contributions cannot exceed the maximum allowable for tax purposes. PacifiCorp's contributions to the 401(k) Plan were $44 million, $40 million and $41 million for the years ended December 31, 2022, 2021 and 2020, respectively.

Employee Benefit Plans | Employee Benefit Plans Defined Benefit Plan MidAmerican Energy sponsors a noncontributory defined benefit pension plan covering a majority of all employees of BHE and its domestic energy subsidiaries other than PacifiCorp and NV Energy, Inc. Benefit obligations under the plan are based on a cash balance arrangement for salaried employees and most union employees and final average pay formulas for other union employees. MidAmerican Energy also maintains noncontributory, nonqualified defined benefit supplemental executive retirement plans ("SERP") for certain active and retired participants. For the years ended December 31, 2022 and 2021, the defined benefit pension plan recorded a settlement loss of $4 million and a settlement gain of $5 million, respectively, for previously unrecognized losses and gains as a result of excess lump sum distributions over the defined threshold. In 2022, the defined benefit pension plan recorded a curtailment gain of $10 million as a result of certain plan amendments. MidAmerican Energy also sponsors certain postretirement healthcare and life insurance benefits covering substantially all retired employees of BHE and its domestic energy subsidiaries other than PacifiCorp and NV Energy, Inc. Under the plans, a majority of all employees of the participating companies may become eligible for these benefits if they reach retirement age. New employees are not eligible for benefits under the plans. MidAmerican Energy has been allowed to recover accrued pension and other postretirement benefit costs in its electric and gas service rates. Net Periodic Benefit Cost For purposes of calculating the expected return on pension plan assets, a market-related value is used. The market-related value of plan assets is calculated by spreading the difference between expected and actual investment returns on equity investments over a five-year period beginning after the first year in which they occur. MidAmerican Energy bills to and is reimbursed currently for affiliates' share of the net periodic benefit costs from all plans in which such affiliates participate. In 2022, 2021 and 2020, MidAmerican Energy's share of the pension net periodic benefit (credit) cost was $(2) million, $(20) million and $(13) million, respectively. MidAmerican Energy's share of the other postretirement net periodic benefit (credit) cost in 2022, 2021 and 2020 totaled $(2) million, $1 million and $(5) million, respectively. Net periodic benefit cost (credit) for the plans of MidAmerican Energy and the aforementioned affiliates included the following components for the years ended December 31 (in millions):

The accumulated benefit obligation and projected benefit obligation for the SERP was $85 million and $85 million for 2022 and $111 million and $111 million for 2021, respectively. Unrecognized Amounts The portion of the funded status of the plans not yet recognized in net periodic benefit cost as of December 31 is as follows (in millions):
MidAmerican Energy sponsors pension and other postretirement benefit plans on behalf of certain of its affiliates in addition to itself, and therefore, the portion of the funded status of the respective plans that has not yet been recognized in net periodic benefit cost is attributable to multiple entities. Additionally, substantially all of MidAmerican Energy's portion of such amounts is either refundable to or recoverable from its customers and is reflected as regulatory liabilities and regulatory assets. A reconciliation of the amounts not yet recognized as components of net periodic benefit cost for the years ended December 31, 2022 and 2021 is as follows (in millions):
Plan Assumptions Assumptions used to determine benefit obligations and net periodic benefit cost were as follows:
(1)Amounts reflected are pretax values. Assumed after-tax returns for a taxable, non-union other postretirement plan were 4.21% for 2022, 2.39% for 2021 and 4.62% for 2020. In establishing its assumption as to the expected return on plan assets, MidAmerican Energy utilizes the asset allocation and return assumptions for each asset class based on historical performance and forward-looking views of the financial markets.
Contributions and Benefit Payments Employer contributions to the pension and other postretirement benefit plans are expected to be $7 million and $2 million, respectively, during 2022. Funding to MidAmerican Energy's qualified pension benefit plan trust is based upon the actuarially determined costs of the plan and the requirements of the Internal Revenue Code, the Employee Retirement Income Security Act of 1974 and the Pension Protection Act of 2006, as amended. MidAmerican Energy considers contributing additional amounts from time to time in order to achieve certain funding levels specified under the Pension Protection Act of 2006, as amended. MidAmerican Energy evaluates a variety of factors, including funded status, income tax laws and regulatory requirements, in determining contributions to its other postretirement benefit plans. Net periodic benefit costs assigned to MidAmerican Energy affiliates are reimbursed currently in accordance with its intercompany administrative services agreement. The expected benefit payments to participants in MidAmerican Energy's pension and other postretirement benefit plans for 2023 through 2027 and for the five years thereafter are summarized below (in millions):
Plan Assets Investment Policy and Asset Allocations MidAmerican Energy's investment policy for its pension and other postretirement benefit plans is to balance risk and return through a diversified portfolio of debt securities, equity securities and other alternative investments. Maturities for debt securities are managed to targets consistent with prudent risk tolerances. The plans retain outside investment consultants to advise on plan investments within the parameters outlined by the Berkshire Hathaway Energy Company Investment Committee. The investment portfolio is managed in line with the investment policy with sufficient liquidity to meet near-term benefit payments. The target allocations (percentage of plan assets) for MidAmerican Energy's pension and other postretirement benefit plan assets are as follows as of December 31, 2022:
(1)For purposes of target allocation percentages and consistent with the plans' investment policy, investment funds are allocated based on the underlying investments in debt and equity securities. Fair Value Measurements The following table presents the fair value of plan assets, by major category, for MidAmerican Energy's defined benefit pension plan (in millions):
(1)Refer to Note 12 for additional discussion regarding the three levels of the fair value hierarchy. (2)Investment funds are comprised of mutual funds and collective trust funds. These funds consist of equity and debt securities of approximately 55% and 45%, respectively, for 2022 and 56% and 44%, respectively, for 2021. Additionally, these funds are invested in U.S. and international securities of approximately 97% and 3%, respectively, for 2022 and 90% and 10%, respectively, for 2021. The following table presents the fair value of plan assets, by major category, for MidAmerican Energy's defined benefit other postretirement plans (in millions):
(1)Refer to Note 12 for additional discussion regarding the three levels of the fair value hierarchy. (2)Investment funds are comprised of mutual funds and collective trust funds. These funds consist of equity and debt securities of approximately 82% and 18%, respectively, for 2022 and 2021. Additionally, these funds are invested in U.S. and international securities of approximately 82% and 18%, respectively, for 2022 and for 2021. For level 1 investments, a readily observable quoted market price or net asset value of an identical security in an active market is used to record the fair value. For level 2 investments, the fair value is determined using pricing models based on observable market inputs. Shares of mutual funds not registered under the Securities Act of 1933, private equity limited partnership interests, common and commingled trust funds and investment entities are reported at fair value based on the net asset value per unit, which is used for expedience purposes. A fund's net asset value is based on the fair value of the underlying assets held by the fund less its liabilities. Defined Contribution Plan MidAmerican Energy sponsors a defined contribution plan ("401(k) plan") covering substantially all employees. MidAmerican Energy's matching contributions are based on each participant's level of contribution, and certain participants receive contributions based on eligible pretax annual compensation. Contributions cannot exceed the maximum allowable for tax purposes. Certain participants now receive enhanced benefits in the 401(k) plan and no longer accrue benefits in the noncontributory defined benefit pension plans. MidAmerican Energy's contributions to the plan were $33 million, $27 million, and $26 million for the years ended December 31, 2022, 2021 and 2020, respectively.
