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.

Defined Benefit Retirement Plans. Retirement plan assets are invested in listed stocks, bonds, hedge funds, real estate and cash equivalents. 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 retirement benefit cost of defined benefit plans includes the following components:

years ended December 31 (in millions)	2020			2019			2018
Service cost	$	39.2		$	30.8		$	31.7
Interest cost		37.1			37.6			33.2
Expected return on assets		(58.4	)		(47.9	)		(46.0	)
Amortization of:
Prior service cost		0.7			—			0.1
Actuarial loss		14.5			16.0			12.8
Settlement charge		3.7			—			2.9
Net periodic benefit cost	$	36.8		$	36.5		$	34.7

The components of net periodic benefit cost, other than service cost, are included in the line item Other nonoperating (income) and expenses, 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:

The accumulated benefit obligation for all defined benefit pension plans was $974.0 million and $878.7 million at December 31, 2020 and 2019, 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)	2020		2019
Projected benefit obligation	$	116.6	$	107.1
Accumulated benefit obligation	$	99.8	$	96.4
Fair value of plan assets	$	0.6	$	0.6

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

	2020	2019
Discount rate	3.16%	3.69%
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:

	2020	2019	2018
Discount rate	3.69%	4.38%	3.76%
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, 2020 and 2019, 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 and MP-2018 mortality improvement scale for the years 2020 and 2019, respectively.

The target allocation for 2020 and the actual pension plan asset allocation by asset class are as follows:

	Percentage of Plan Assets
		2020
		Target	December 31
Asset Class		Allocation	2020	2019
Equity securities		56%	61%	64%
Debt securities		24%	24%	28%
Real estate		10%	8%	5%
Private infrastructure		6%	5%	0%
Hedge funds		4%	2%	3%
Total		100%	100%	100%

The Company’s investment strategy is for approximately 45% of equity securities, excluding hedge funds and real estate, to be invested in mid-sized to large capitalization U.S. funds, with the remaining invested in small capitalization, emerging markets and international 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. The fair values of real estate

investments generally do not reflect transaction costs that may be incurred upon disposition of the real estate investments and do not necessarily represent the prices at which the real estate investments would be sold or repaid, since market prices of real estate investments can only be determined by negotiation between a willing buyer and seller. An independent valuation consultant is employed to determine the fair value of the real estate investments. 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. 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 the fund for which there is no quoted market price, fair value is determined by the Trustees/General Partner based on discounted expected future cash flows prepared by third-party professionals.  

In 2020 and 2019, the Company made combined pension plan and SERP contributions of $88.4 million and $58.9 million, respectively. The Company currently estimates that it will contribute $82.6 million to its pension plans in 2021.
