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)	2021		2020		2021		2020
Service cost	$	118	$	120	$	361	$	365
Interest cost	10		19		31		56
Amortization of actuarial income	(112)		(82)		(333)		(260)
Net periodic benefit cost	$	16	$	57	$	59	$	161

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.
