Note 7 – Employee Benefit Plans

Pension Plans

We have noncontributory defined benefit pension plans for eligible employees hired prior to January 1, 2019. Eligible employees earn compensation credits based on a cash balance formula. As of January 1, 2020, certain active employees are no longer eligible to receive compensation credits.

Other Postretirement Benefits

We provide subsidized retiree medical benefits to a closed group of participants as well as retiree life insurance benefits to eligible participants. Medical benefits for Medicare eligible participants are paid through contributions to health reimbursement accounts. Benefits for all other participants are provided through a self-insured medical plan, which includes participant contributions and contains other cost-sharing features such as deductibles, co-payments, and co-insurance.

Defined Contribution Plan

We have a defined contribution plan for the benefit of substantially all employees. Plan participants may contribute a portion of their compensation on a pre-tax or after-tax basis. Generally, we match employee contributions up to 6 percent of eligible compensation. Additionally, eligible active employees that do not receive compensation credits under the defined benefit pension plan are eligible for an additional annual fixed-percentage contribution made by us to the defined contribution plan. Our contributions charged to expense were $53 million in 2022, $45 million in 2021, and $42 million in 2020.

Key Assumptions

The weighted-average assumptions utilized to determine benefit obligations and Net periodic benefit cost (credit) as of December 31 are as follows:

	Pension Benefits						Other Postretirement  Benefits
	2022		2021		2020		2022		2021		2020
Benefit obligations:
Discount rate	5.16	%	2.82	%	2.45	%	5.20	%	2.93	%	2.59	%
Rate of compensation increase	3.58		3.67		3.76		N/A		N/A		N/A
Cash balance interest crediting rate	3.50		3.00		3.00		N/A		N/A		N/A
Net periodic benefit cost (credit):
Discount rate	2.84	%	2.45	%	3.08	%	2.93	%	2.59	%	3.27	%
Expected long-term rate of return on plan assets	3.81		3.69		4.67		3.67		3.61		4.39
Rate of compensation increase	3.67		3.76		3.68		N/A		N/A		N/A
Cash balance interest crediting rate	3.00		3.00		3.50		N/A		N/A		N/A

We use mortality tables issued by the Society of Actuaries to measure the benefit obligations.

The assumed health care cost trend rate for 2023 is 6.8 percent. This rate decreases to 4.5 percent by 2032.

Plan Assets

The plans’ investment objectives include a framework to manage the volatility of the plans’ funded status and minimize future cash contributions. The plans follow a policy of diversifying the investments across various asset classes, strategies, and investment managers.

The investment policy for the pension plans includes target asset allocation percentages as well as permitted and prohibited investments designed to mitigate risks associated with investing. The December 31, 2022, target asset allocation was 25 percent equity securities and 75 percent fixed income securities, including investments in equity and fixed income mutual funds, commingled investment funds, and separate accounts.

The fair values of our pension and other postretirement benefits plan assets by asset class at December 31 are as follows:

Total assets at fair value					$	1,336					$	287

____________

(1)    Level 1 includes assets with fair values based on quoted prices in active markets for identical assets. Cash management funds, equity securities traded on U.S. exchanges, U.S. Treasury securities, and mutual funds are included in this level.

(2)    Level 2 includes assets with fair values determined by using significant other observable inputs. This level includes equity securities traded on active foreign exchanges and fixed income securities, other than U.S. Treasury securities, that are valued primarily using pricing models which incorporate observable inputs such as benchmark yields, reported trades, broker/dealer quotes, and issuer spreads.

(3)    The commingled investment funds are measured at fair value using net asset value per share. Certain standard withdrawal restrictions generally apply, which may include redemption notification period restrictions ranging from 1 day to 15 days.

Plan Benefit Payments and Employer Contributions

Following are the expected benefit payments, which reflect the same assumptions previously discussed and future service as appropriate.

	Pension Benefits		Other Postretirement Benefits

2025	84		12
2026	81		12
2027	80		11
