Service cost	$	320		$	356		$	969		$	1,047
Interest cost	159			108			483			317
Expected return on plan assets	(317		)	(271		)	(960		)	(797		)
Net amortization and deferral	131			249			398			731
Net periodic benefit cost	$	293		$	442		$	890		$	1,298

The weighted average expected long-term rate of return on plan assets used to determine the net periodic benefit cost for each of the three and nine months ended June 30, 2018 and July 1, 2017 was 5.5%.
