Other Income and Expenses [Abstract]

Our primary measure of segment performance as shown in Note 18, "Segment Reporting," excludes certain items we do not believe are representative of the ongoing operations of the segment. Excluding these items from our segment measure of performance allows for better year over year comparison:

	2021		2020
	(In thousands)
Restructuring and other, net	$	3,028	$	20,621
