Retirement Plans, Postretirement and Postemployment Benefits

Note K: Retirement Plans, Postretirement and Postemployment Benefits

The Company sponsors defined benefit retirement plans that cover substantially all employees. Additionally, the Company provides other postretirement benefits for certain employees, including medical benefits for retirees and their spouses and retiree life insurance. Employees starting on or after January 1, 2002 are not eligible for postretirement welfare plans. The Company also provides certain benefits, such as disability benefits, to former or inactive employees after employment but before retirement.

The measurement date for the Company’s defined benefit plans, postretirement benefit plans and postemployment benefit plans is December 31. During 2022, the Company amended its qualified pension plan to provide an enhanced benefit for eligible hourly active participants who retire subsequent to April 30, 2022, which resulted in a remeasurement of the qualified pension plan as of February 28, 2022. The remeasurement increased the defined benefit plans’ unrecognized prior service cost by $47.6 million.

Defined Benefit Retirement Plans. Defined retirement benefits for salaried employees are based on each employee’s years of service and average compensation for a specified period of time before retirement. Defined retirement benefits for hourly employees are generally stated amounts for specified periods of service.

The Company sponsors a Supplemental Excess Retirement Plan (SERP) that generally provides for the payment of retirement benefits in excess of allowable Internal Revenue Code limits. The SERP generally provides for a lump-sum payment of vested benefits. When these benefit payments exceed the sum of the service and interest costs for the SERP during a year, the Company recognizes a pro rata portion of the SERP’s unrecognized actuarial loss as settlement expense.

The net periodic benefit cost of defined benefit plans includes the following components:

years ended December 31 (in millions)	2022			2021			2020
Service cost	$	48.1		$	46.2		$	39.2
Interest cost		41.2			35.7			37.1
Expected return on assets		(77.3	)		(70.5	)		(58.4	)
Amortization of:
Prior service cost		4.9			0.8			0.7
Actuarial loss		3.9			12.2			14.5
Settlement charge		4.6			—			3.7
Net periodic benefit cost	$	25.4		$	24.4		$	36.8

The components of net periodic benefit cost, other than service cost, are included in the line item Other nonoperating income, net, in the consolidated statements of earnings. Based on the roles of the employees, service cost is included in Cost of revenues – products and services or Selling, general and administrative expenses line items in the consolidated statements of earnings.

The expected return on assets is calculated by applying an annually selected expected long-term rate of return assumption to the estimated fair value of the plan assets during the year, giving consideration to contributions and benefits paid.

The Company recognized the following amounts in consolidated comprehensive earnings:

years ended December 31
(in millions)	2022			2021			2020
Actuarial (gain) loss	$	(114.5	)	$	(67.5	)	$	34.7

Settlement charge		(4.6	)		—			(3.7	)
Total	$	(79.8	)	$	(80.5	)	$	15.8

Accumulated other comprehensive loss includes the following amounts that have not yet been recognized in net periodic benefit cost:

December 31	2022				2021
(in millions)	Gross		Net of tax		Gross		Net of tax
Prior service cost	$	48.2	$	20.3	$	5.1	$	3.0
Actuarial loss		43.2		18.2		166.2		97.0
Total	$	91.4	$	38.5	$	171.3	$	100.0

The defined benefit plans’ change in projected benefit obligation is as follows:

years ended December 31
(in millions)	2022			2021
Net projected benefit obligation at beginning of year	$	1,135.5		$	1,111.9
Service cost		48.1			46.2
Interest cost		41.2			35.7
Actuarial gain		(363.3	)		(16.2	)
Gross benefits paid		(52.0	)		(42.1	)
Plan amendments		48.1			—
Net projected benefit obligation at end of year	$	857.6		$	1,135.5

The actuarial gain in 2022 was primarily attributable to a higher discount rate compared with the prior year.

The Company’s change in plan assets, funded status and amounts recognized on the Company’s consolidated balance sheets are as follows:

years ended December 31
(in millions)	2022			2021
Fair value of plan assets at beginning of year	$	1,200.3		$	1,037.9
Actual return on plan assets, net		(171.4	)		121.7
Employer contributions		90.2			82.8
Gross benefits paid		(52.0	)		(42.1	)

Funded status of the plan at end of year	$	209.5	$	64.8
Accrued benefit credit	$	209.5	$	64.8

December 31
(in millions)	2022			2021
Amounts recognized on consolidated balance sheets consist of:
Noncurrent asset	$	295.3		$	179.2
Current liability		(6.8	)		(14.8	)
Noncurrent liability		(79.0	)		(99.6	)
Net amount recognized at end of year	$	209.5		$	64.8

The accumulated benefit obligation for all defined benefit pension plans was $789.6 million and $1.00 billion at December 31, 2022 and 2021, respectively.

Benefit obligations and fair value of plan assets for pension plans with accumulated benefit obligations in excess of plan assets are as follows:

December 31
(in millions)	2022		2021
Projected benefit obligation	$	86.3	$	115.0
Accumulated benefit obligation	$	79.5	$	101.8
Fair value of plan assets	$	0.5	$	0.7

Weighted-average assumptions used to determine benefit obligations as of December 31 are:

	2022	2021
Discount rate	5.88%	3.23%
Rate of increase in future compensation levels	4.50%	4.50%

Weighted-average assumptions used to determine net periodic benefit cost for the years ended December 31 are:

	2022	2021	2020
Discount rate	3.44%	3.16%	3.69%
Rate of increase in future compensation levels	4.50%	4.50%	4.50%
Expected long-term rate of return on assets	6.75%	6.75%	6.75%

The expected long-term rate of return on assets is based on a building-block approach, whereby the components are weighted based on the allocation of pension plan assets.

As of December 31, 2022 and 2021, the Company estimated the remaining lives of participants in the pension plans using the Pri-2012 Base tables. The no-collar table was used for salaried participants and the blue-collar table was used for hourly participants; both tables were adjusted to reflect the experience of the Company’s participants. The Company used the MP-2020 mortality improvement scale for the years 2022 and 2021.

Retirement plan assets are invested in listed stocks, bonds, real estate, private infrastructure and cash equivalents. The target allocation for 2022 and the actual pension plan asset allocation by asset class are as follows:

	Percentage of Plan Assets
		2022
		Target	December 31
Asset Class		Allocation	2022	2021
Equity securities		56%	54%	59%
Debt securities		28%	24%	27%
Real estate		10%	14%	7%
Private infrastructure		6%	8%	7%
Total		100%	100%	100%

The Company’s investment strategy is for equity securities to be invested in mid-sized to large capitalization U.S. funds, and small capitalization, international and emerging growth funds. Debt securities, or fixed income investments, are invested in funds benchmarked to the Barclays U.S. Aggregate Bond Index.

The fair values of pension plan assets by asset class and fair value hierarchy level are as follows:

1.These investments are common collective investment trusts valued using the net asset value (NAV) unit price provided by the fund administrator. The NAV is based on the value of the underlying assets owned by the fund.

Real estate investments are stated at estimated fair value, which is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Real estate investments are valued at NAV based on the plan’s proportionate shares of the real estate funds’ fair value as recorded by the trustees/general partner of the funds. The funds are real estate investment trust based funds that offer participation in an actively managed, primarily core portfolio of equity real estate. The funds allocate gains, losses and expenses to investors based on the ownership percentage to determine the NAV. Private infrastructure assets represent investments in a fund that is stated at fair value. For financial assets in the fund that are actively traded in organized financial markets, fair value is based on exchange-quoted market prices. For investments in a fund for which there is no quoted market price, fair value is determined by the trustees/general partner of the fund based on discounted expected future cash flows prepared by third-party professionals. The value of hedge funds is based on the values of the sub-fund investments. In determining the fair value of each sub-fund’s investment, the hedge funds’ board of trustees uses the values provided by the sub-funds and any other considerations that may, in its judgment, increase or decrease such estimated value.

In 2022 and 2021, the Company made combined pension plan and SERP contributions of $90.2 million and $82.8 million, respectively. The Company currently estimates that it will contribute $36.5 million to its pension plans in 2023.
