Retirement Benefit Plans

The Company and certain of its subsidiaries sponsor defined benefit pension plans covering some of its employees. The components of net periodic benefit cost of the Company’s defined benefit plans are as follows:



	Three Months Ended December 31,
	2019			2018
Service cost	$	85		$	75
Interest cost	208			264
Expected return on plan assets	(376		)	(393		)
Amortization of net loss	188			107
Net periodic cost	$	105		$	53

During the three months ended December 31, 2019 and 2018, the Company made $188 and $22 in contributions, respectively, to its defined benefit pension plans. The Company anticipates making $332 of additional cash contributions to fund its defined benefit pension plans during the balance of fiscal 2020 and will use carryover balances from previous periods that have been available for use as a credit to reduce the amount of cash contributions that the Company is required to make to certain defined benefit plans in fiscal 2020. The Company's ability to elect to use such carryover balance will be determined based on the actual funded status of each defined benefit pension plan relative to the plan's minimum regulatory funding requirements. The Company does not anticipate making cash contributions above the minimum funding requirement to fund its defined benefit pension plans during the balance of fiscal 2020.

On November 26, 2019, the Company ratified a new collective bargaining agreement with one of its bargaining units. Included within the agreement was a provision to withdraw from its existing multi-employer plan resulting in the imposition of a withdrawal liability. The withdrawal liability of $739 was recorded within the cost of goods sold line of the consolidated condensed statement of operations and is included in other long-term liabilities and the current portion (next four quarterly installments) in accrued liabilities of the consolidated condensed balance sheets, payable in quarterly installments over the next 20 years.
