Retirement Benefits [Abstract]

Employee Benefit Plans

Many of our defined benefit pension and profit sharing plans have been frozen and replaced with defined contribution plans. We have a liability for the benefits earned under these inactive plans prior to the date the benefits were frozen. We also have several active defined benefit plans that provide benefits based on years of service. Our defined contribution plans generally include both company and employee contributions which are based on predetermined percentages of compensation earned by the employee.

In addition to freezing the benefits of our defined benefit pension plans, we have also eliminated nearly all of our post-retirement medical benefits.

Defined Contribution Plans

We recorded the following contributions to the defined contribution plans (in millions):

Pension and Post-retirement Benefit Plans

Pension Settlement Activity in 2019

On April 3, 2019, we entered into an agreement with Pacific Life Insurance Company to purchase a group annuity contract and transfer $100 million of our pension plan assets and $105.6 million of related pension benefit obligations.  In the second quarter of 2019, we recognized a $60.6 million pension settlement charge in the Statement of Operations and reclassified $5.6 million of pension benefit obligations to AOCL as a result of this transaction. 

On October 15, 2019, we entered into an agreement with Pacific Life Insurance Company to purchase a group annuity contract and transfer $73.5 million of our pension plan assets and $77.9 million of related benefit obligations. In the fourth quarter of 2019, we recognized a $38.6 million pension settlement charge in the Statement of Operations and reclassified $4.4 million of pension benefit obligations to AOCL as a result of this transaction.

Assumptions

The following tables set forth the weighted-average assumptions used to determine Benefit obligations and Net periodic benefit cost for the U.S.-based plans in 2021 and 2020:

	Pension Benefits
	2021		2020
Weighted-average assumptions used to determine benefit obligations as of December 31:
Discount rate	2.69	%	2.40	%
Rate of compensation increase	4.1	%	4.13	%

	Pension Benefits
	2021		2020		2019
Weighted-average assumptions used to determine net periodic benefit cost for the years ended December 31:
Discount rate - service cost	1.85	%	2.89	%	3.96	%
Discount rate - interest cost	2.16	%	2.99	%	3.67	%
Expected long-term return on plan assets	6.50	%	6.50	%	6.50	%
Rate of compensation increase	4.13	%	4.23	%	4.23	%

The following tables set forth the weighted-average assumptions used to determine Benefit obligations and Net periodic benefit cost for the non-U.S.-based plans in 2021 and 2020:

	Pension Benefits
	2021		2020
Weighted-average assumptions used to determine benefit obligations as of December 31:
Discount rate	1.99	%	1.48	%
Rate of compensation increase	3.14	%	3.17	%

	Pension Benefits
	2021		2020		2019
Weighted-average assumptions used to determine net periodic benefit cost for the years ended December 31:
Discount rate - service cost	0.42	%	0.73	%	1.6	%
Discount rate - interest cost	1.51	%	2.3	%	2.98	%
Expected long-term return on plan assets	2.10	%	3.31	%	3.92	%
Rate of compensation increase	3.17	%	3.20	%	3.77	%

To develop the expected long-term rate of return on assets assumption for the U.S. plans, we considered the historical returns for each asset category, as well as the target asset allocation of the pension portfolio and the effect of periodic balancing. These results were adjusted for the payment of reasonable expenses of the plan from plan assets. This resulted in the selection of the 6.50% long-term rate of return on assets assumption. A similar process was followed for the non-U.S.-based plans.

To select a discount rate for the purpose of valuing the plan obligations for the U.S. plans, we performed an analysis in which the projected cash flows from defined benefit and retiree healthcare plans was matched with a yield curve based on the appropriate universe of high-quality corporate bonds that were available. We used the results of the yield curve analysis to select the discount rate for each plan. The analysis was completed separately for each U.S. pension and OPEB plan. A similar process was followed for the non-U.S.-based plans with sufficient corporate bond information. In other countries, the discount rate was selected based on the approximate duration of plan obligations.

Assumed health care cost trend rates have an effect on the amounts reported for our healthcare plan. The following table sets forth the healthcare trend rate assumptions used:

	2021		2020
Assumed health care cost trend rates as of December 31:
Health care cost trend rate assumed for next year	6.00	%	6.00	%
Rate to which the cost rate is assumed to decline (the ultimate trend rate)	5.00	%	5.00	%
Year that the rate reaches the ultimate trend rate	2025		2023

Expected future benefit payments are shown in the table below (in millions):

	For the Years Ended December 31,
	2022		2023		2024		2025		2026		2027-2031
Pension benefits	$	12.0	$	6.8	$	13.0	$	33.0	$	8.8	$	76.9

Composition of Pension Plan Assets

We believe asset returns can be optimized at an acceptable level of risk by adequately diversifying the plan assets between equity and fixed income. In the fourth quarter of 2019, we changed the targeted allocations for our plan assets. The targeted allocation for fixed income and cash investments was changed to 50%, and the targeted allocation for equity investments was changed to 50%. Our targeted exposure to International equity including emerging markets was changed to 6.0% of total assets and our exposure to domestic equity was changed to 44.0%. Our U.S. pension plan represents 78%, our Canadian pension plan 9%, and our United Kingdom (“U.K.”) pension plan 13% of the total fair value of our plan assets as of December 31, 2021.

Our U.S. pension plans’ weighted-average asset allocations as of December 31, 2021 and 2020, by asset category, were as follows:

	Plan Assets as of December 31,
Asset Category:	2021		2020
U.S. equity	36.1	%	34.8	%
International equity	15.5	%	17.0	%
Fixed income	48.2	%	48.0	%
Money market/cash	0.2	%	0.2	%
Total	100.0	%	100.0	%

Our U.S. pension plans’ assets were invested according to the following targets:

Asset Category:	Target
U.S. equity	44.0	%
International equity	6.0	%
Fixed income	50.0	%

Our Canadian pension plans were invested approximately 74% in Canadian bonds and 26% in equities. Our U.K. pension plan was invested in fixed income securities, including corporate and government bonds.

The fair values of our pension plan assets, by asset category, were as follows (in millions):

The majority of our commingled pool/collective trusts, mutual funds, balanced pension trusts and pension funds are managed by professional investment advisors. The NAVs per share are furnished in monthly and/or quarterly statements received from the investment advisors and reflect valuations based upon their pricing policies. We assessed the fair value classification of these investments as Level 2 for commingled pool/collective trusts, balanced pension trusts and pension funds based on an examination of their pricing policies and the related controls and procedures. The fair values we report are based on the pool, trust or fund’s NAV per share. The NAVs per share are calculated periodically (daily or no less than one time per month) as the aggregate value of each pool or trust’s underlying assets divided by the number of units owned. See Note 17 for information about our fair value hierarchies and valuation techniques.
