Defined Benefit Pension and Other Postretirement Benefit Plans
The Company sponsors eleven defined benefit pension plans: six in Europe, one in Singapore, two in Mexico, and two in Japan. The Company funds the pension liabilities in accordance with laws and regulations applicable to those plans.
In addition, the Company maintains two frozen post-retirement benefit plans in the United States: health care and life insurance benefits for certain retired United States employees who reached retirement age while working for the Company. The health care plan is contributory, with participants’ contributions adjusted annually. The life insurance plan is non-contributory. Costs recognized for benefit plans are recorded using estimated amounts which may change as actual costs for the fiscal year are determined.
The components of net periodic benefit (income) costs relating to the Company’s pension and other postretirement benefit plans for the three months ended December 31, 2018 and 2017 are as follows (amounts in thousands):
