Note 4.   Employee Benefit Plans

We sponsor defined benefit pension plans covering substantially all U.S. employees.  Net periodic pension cost for the plans consisted of the following for the three-month periods ended March 31, 2022 and 2021 (in thousands):

	Three Months Ended March 31,
	2022			2021
Service cost	$	1,566		$	1,455
Interest cost		1,369			1,248
Expected return on plan assets		(3,363	)		(2,313	)
Amortization of prior service cost		128			99
Amortization of net loss		512			1,125
Net periodic pension cost	$	212		$	1,614

The service cost component of net periodic pension cost is included in the same line items of our condensed consolidated financial statements as other employee compensation costs, and the net gain of $1.4 million and net expense of $0.2 million for the three-month periods ended March 31, 2022 and 2021, respectively, related to all other components of net periodic pension cost is included in other (expense) income on our condensed consolidated statements of operations and comprehensive (loss) income.

We do not expect to be required to contribute to our defined benefit pension plans in 2022, but may do so.
