Retirement Benefits [Abstract]

Benefit Plans

Benefit Plans

Certain of our U.S. and international subsidiaries sponsor defined benefit pension plans. In addition, we provide minimal death benefits for certain U.S. retirees and pay a portion of healthcare costs for retired U.S. salaried employees and their dependents. Benefits for participants are coordinated with Medicare when possible. We also sponsor a defined contribution plan for certain salaried and hourly U.S. employees. Our 401(k) plan contributions were $22.8 million for 2022, $19.5 million for 2021 and $16.8 million for 2020.

Pension and Other Retirement Benefits

Net periodic benefit cost by geographic location is as follows:

	Pension benefits						Other retirement benefits
($ in millions)	2022		2021		2020		2022		2021		2020
U.S. plans	$	51.7	$	(2.3)	$	1.2	$	(1.3)	$	(1.8)	$	(2.4)

Net periodic benefit cost	$	54.1	$	(0.4)	$	2.7	$	(1.3)	$	(1.8)	$	(2.4)

The service cost component included within net periodic benefit cost is considered employee compensation and is therefore presented within the selling, general, and administrative and costs of goods and services sold financial statement line items of our consolidated statements of income. The remaining components of net periodic benefit cost are reported separately and are therefore presented within the other nonoperating expense (income) financial statement line item of our consolidated statements of income.

During 2021, the Company approved the termination of our U.S. qualified defined benefit pension plan (the "U.S. pension plan"). During 2021, a Notice of Intent to Terminate was sent to all interested parties and in 2022 a favorable determination letter was received from the Internal Revenue Service. During 2022, lump sum payments were offered to all current employees and former employees with vested benefits under the U.S. pension plan. A cash contribution of $7.1 million was made by the Company to ensure the U.S. pension plan was fully funded in preparation for the group annuity contract purchase which was executed in August of 2022 to settle the outstanding benefit obligations, as well as to cover any ancillary benefits and expenses remaining. During 2022, we recorded a $52.2 million pension settlement charge within other nonoperating expense (income), which primarily related to the full settlement and relief of the historical balance sheet position, inclusive of accumulated other comprehensive income, of the U.S. pension plan. During 2021 and 2020, we recorded a $1.8 million and $3.7 million, respectively, pension settlement charge within other nonoperating expense (income), as we determined that normal-course lump-sum payments for the U.S. pension plan exceeded the threshold for settlement accounting under U.S. GAAP for the year.

During 2022, we contributed $7.1 million to our U.S. pension plan. During 2021, we did not contribute to our U.S. pension plan.

The following table presents the changes in the benefit obligation and the fair value of plan assets, as well as the funded status of the plans:

	Pension benefits				Other retirement benefits

International pension plan assets, at fair value, included in the preceding table were $29.4 million and $49.3 million at December 31, 2022 and 2021, respectively.

Amounts recognized in the balance sheet were as follows:

	Pension benefits				Other retirement benefits
($ in millions)	2022		2021		2022		2021
Noncurrent assets	$	0.3	$	16.7	$	—	$	—

The amounts in accumulated other comprehensive loss, pre-tax, consisted of:

	Pension benefits				Other retirement benefits
($ in millions)	2022		2021		2022		2021
Net actuarial loss (gain)	$	16.7	$	56.5	$	(5.2)	$	(4.7)
Prior service cost (credit)	(1.1)		(1.3)		—		—
Total	$	15.6	$	55.2	$	(5.2)	$	(4.7)

The accumulated benefit obligation for all defined benefit pension plans was $52.4 million and $265.2 million at December 31, 2022 and 2021, respectively, including $46.0 million and $73.0 million, respectively, for international pension plans.

As of December 31, 2022, our United Kingdom qualified defined benefit pension plan had plan assets in excess of its obligations. As of December 31, 2021, our U.S. and United Kingdom qualified defined benefit pension plan had assets in excess of its obligations. As of December 31, 2022 and December 31, 2021, our other defined benefit pension plans had projected benefit obligations and accumulated benefit obligations in excess of plan assets.

Benefit payments expected to be paid under our defined benefit pension and other retirement benefit plans in the next ten years are as follows. The expected benefit payments listed correspond to regular ongoing benefit payments expected to be made by the plan during future years.

($ in millions)	Domestic		International		Total
2023	$	1.5	$	2.2	$	3.7
2024	1.4		2.5		3.9
2025	1.3		2.8		4.1
2026	1.2		3.3		4.5
2027	1.0		3.7		4.7
2028 to 2032	4.2		17.8		22.0
	$	10.6	$	32.3	$	42.9

In 2023, we expect to contribute $0.6 million to pension plans, all of which is in the U.S. In addition, we expect to contribute $0.6 million for other retirement benefits in 2023. We periodically consider additional, voluntary contributions depending on the investment returns generated by pension plan assets, changes in benefit obligation projections and other factors.

Weighted average assumptions used to determine net periodic benefit cost were as follows:

	Pension benefits						Other retirement benefits
	2022		2021		2020		2022		2021		2020
Discount rate	2.48	%	2.29	%	2.61	%	2.75	%	2.30	%	3.20	%
Rate of compensation increase	2.79	%	2.41	%	2.33	%	—		—		—
Expected long-term rate of return on assets	4.14	%	4.93	%	5.10	%	—		—		—

Weighted average assumptions used to determine the benefit obligations were as follows:

	Pension benefits				Other retirement benefits
	2022		2021		2022		2021
Discount rate	4.35	%	2.48	%	5.55	%	2.75	%
Rate of compensation increase	3.09	%	2.79	%	—		—

The discount rate used to determine the benefit obligations for U.S. pension plans was 5.55% and 2.95% as of December 31, 2022 and 2021, respectively. The weighted average discount rate used to determine the benefit obligations for all international plans was 4.20% and 1.32% as of December 31, 2022 and 2021, respectively. The weighted average rate of compensation increase for all international plans was 3.09% for 2022 and 2.79% for 2021, while there was no rate increase for the U.S. plans since they are frozen. Other retirement benefits were only available to U.S. employees. The expected long-term rate of return for U.S. plans was 3.70% for 2022, 5.10% for 2021 and 5.10% for 2020.

The assumed healthcare cost trend rate used to determine benefit obligations was 6.75% for all participants in 2022, decreasing to 5.0% by 2030. The assumed healthcare cost trend rate used to determine net periodic benefit cost was 6.25% for all participants in 2022, decreasing to 5.0% by 2027.

The defined pension plan benefit obligation decreased for the year ended December 31, 2022 primarily due to settlement losses recognized during the year, as well as an increase in the discount rate used to calculate the obligation. The net actuarial losses will be impacted in future periods by actual asset returns, discount rate changes, currency exchange rate fluctuations, actual demographic experience, and certain other factors. The other retirement plan benefit obligation decreased due an increase in the discount rate used to calculate the obligation.

The Company has cash balance plans and other plans with promised interest crediting rates. For these plans, the interest crediting rates are set in line with plan rules or country legislation and do not change with market conditions.

The weighted average interest crediting rating used to determine net periodic benefit cost by geographic location for our pension plans, at December 31, were as follows:

	2022		2021		2020
U.S. plans	3.31	%	3.31	%	3.30	%
International plans	1.75	%	0.67	%	0.52	%

The weighted average asset allocations by asset category for our pension plans, at December 31, were as follows:

	2022		2021
Equity securities	28	%	12	%
Debt securities	68	%	86	%
Other	4	%	2	%
	100	%	100	%

Diversification across and within asset classes is the primary means by which we mitigate risk. We maintain guidelines for all asset and sub-asset categories in order to avoid excessive investment concentrations. Fund assets are monitored on a regular basis. If at any time the fund asset allocation is not within the acceptable allocation range, funds will be reallocated. We also review the fund on a regular basis to ensure that the investment returns received are consistent with the short-term and long-term goals of the fund and with comparable market returns. We are prohibited from pledging fund securities and from investing pension fund assets in our own stock, securities on margin or derivative securities.

The following are the target asset allocations and acceptable allocation ranges across:

	Target allocation	Allocation range
Equity securities	27%	25% - 30%
Debt securities	68%	63% - 68%
Other	5%	2% - 7%

The following tables present the fair value of our pension plan assets, utilizing the fair value hierarchy discussed in Note 12, Fair Value Measurements. In accordance with U.S. GAAP, certain pension plan assets measured at net asset value (“NAV”) have not been classified in the fair value hierarchy.
