Retirement Benefits [Abstract]

Defined Benefit Pension Plans

We sponsor both funded and unfunded defined benefit pension plans offering death and disability, retirement, and special termination benefits for certain of our international employees, primarily in Germany, France, Indonesia, India, and Italy. The defined benefit obligation is calculated annually by using the projected unit credit method. The measurement date for the pension plans was December 31, 2020.

The following tables set forth the components of the changes in benefit obligations and fair value of plan assets:

Amounts recognized in OCI (pre-tax) are as follows:

	Year Ended December 31,
In thousands	2020		2019		2018
Net actuarial (gain) loss	$	8,734	$	8,762	$	(3,191)

Other	—		(160)		124
Other comprehensive (income) loss	$	6,189	$	6,110	$	(3,939)

If actuarial gains and losses exceed ten percent of the greater of plan assets or plan liabilities, we amortize them over the employees' average future service period. The estimated net actuarial loss and prior service cost that will be amortized from AOCI into net periodic benefit cost during 2021 is $2.9 million.

Net periodic pension benefit cost for our plans include the following components:

	Year Ended December 31,
In thousands	2020		2019		2018
Service cost	$	4,027	$	3,711	$	4,034
Interest cost	1,817		2,278		2,324
Expected return on plan assets	(453)		(608)		(670)
Amortization of prior service costs	68		68		61
Amortization of actuarial net loss	2,255		1,648		1,533
Settlement	286		250		1
Curtailment	—		—		1
Net periodic benefit cost	$	8,000	$	7,347	$	7,284

The components of net periodic benefit cost, other than the service cost component, are included in total other income (expense) on the Consolidated Statements of Operations.

The significant actuarial weighted average assumptions used in determining the benefit obligations and net periodic benefit cost for our benefit plans are as follows:

	Year Ended December 31,
	2020		2019		2018
Actuarial assumptions used to determine benefit obligations at end of period:
Discount rate	1.10	%	1.76	%	2.24	%
Expected annual rate of compensation increase	3.68	%	3.76	%	3.60	%
Actuarial assumptions used to determine net periodic benefit cost for the period:
Discount rate	1.76	%	2.24	%	2.21	%
Expected rate of return on plan assets	4.89	%	5.19	%	5.58	%
Expected annual rate of compensation increase	3.76	%	3.60	%	3.64	%

We determine a discount rate for our plans based on the estimated duration of each plan's liabilities. For euro denominated defined benefit pension plans, which represent 92% of our projected benefit obligation, we use discount rates with consideration of the duration of each of the plans, using a hypothetical yield curve developed from euro-denominated AA-rated corporate bond issues. These bonds are assigned different weights to adjust their relative influence on the yield curve, and the highest and lowest yielding 10% of bonds are excluded within each maturity group. The discount rates used, depending on the duration of the plans, were between 0.20% and 0.75%.

Our expected rate of return on plan assets is derived from a study of actual historic returns achieved and anticipated future long-term performance of plan assets, specific to plan investment asset category. While the study primarily gives consideration to recent insurers' performance and historical returns, the assumption represents a long-term prospective return.

The total accumulated benefit obligation for our defined benefit pension plans was $121.7 million and $105.1 million at December 31, 2020 and 2019.

The total obligations and fair value of plan assets for plans with projected benefit obligations and accumulated benefit obligations exceeding the fair value of plan assets are as follows:

In thousands	December 31,
	2020		2019
Projected benefit obligation	$	132,732	$	110,656
Accumulated benefit obligation	121,747		101,611
Fair value of plan assets	10,206		9,059

Our asset investment strategy focuses on maintaining a portfolio using primarily insurance funds, which are accounted for as investments and measured at fair value, in order to achieve our long-term investment objectives on a risk adjusted basis. Our general funding policy for these qualified pension plans is to contribute amounts sufficient to satisfy regulatory funding standards of the respective countries for each plan.

The fair values of our plan investments by asset category are as follows:

As the plan assets and contributions are not significant to our total company assets, no further disclosures are considered material.

Annual benefit payments for the next 10 years, including amounts to be paid from our assets for unfunded plans and reflecting expected future service, as appropriate, are expected to be paid as follows:
