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 months ended March 31, 2021 and 2020 (in thousands):

	Three Months Ended March 31,
	2021			2020
Service cost	$	1,455		$	1,334
Interest cost		1,248			1,404
Expected return on plan assets		(2,313	)		(1,872	)
Amortization of prior service cost		99			29
Amortization of net loss		1,125			1,163
Net periodic pension cost	$	1,614		$	2,058

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 expense for the three months ended March 31, 2021 and 2020 of $0.2 million and $0.7 million, 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 income (loss).

In January 2021, we contributed $16.8 million in shares of our common stock to our supplemental executive retirement plan, and expect to contribute approximately $0.8 million during the remainder of 2021. We do not expect to be required to contribute to our defined benefit pension plans in 2021, but may do so.
