Net periodic benefit cost in 2017 was significantly impacted by the termination and settlement of the Company's qualified U.S. pension plan in December 2016.  The settlement resulted in the immediate recognition of previously unrecognized actuarial items related to the plan in 2016 that were recorded in accumulated other comprehensive income and were being amortized into net periodic pension cost. A final reconciliation of participant data subject to the settlement annuity contract was completed during the second fiscal quarter of 2017.  The final annuity pricing adjustment and related items did not have a material impact on the Company's financial results.

The Company contributed $4,409 to the Company's Taiwanese pension plans to improve the funded status of those plans in 2017.
