Postemployment Benefits

Our domestic employees participate in severance plans which provide severance benefits to eligible employees meeting the plans’ qualifications, primarily for involuntary termination without cause.

The components of net periodic postemployment benefit cost applicable to our severance plans were as follows:

	Three Months Ended				Nine Months Ended
	March 31				March 31
(Amounts in Thousands)	2022		2021		2022		2021
Service cost	$	123	$	118	$	388	$	361
Interest cost	13		10		41		31
Amortization of actuarial income	(129)		(112)		(399)		(333)
Net periodic benefit cost	$	7	$	16	$	30	$	59

The benefit cost in the above table includes only normal recurring levels of severance activity, as estimated using an actuarial method. Unusual or non-recurring severance actions, such as restructuring actions, are not estimable using actuarial methods and are expensed in accordance with the applicable U.S. GAAP.
