Retirement Benefit Plans

Effective at the beginning of fiscal 2018, the Company retrospectively adopted ASU No. 2017-07. See Recently Adopted Accounting Pronouncements in Note 1 for further discussion. As a result, only the service cost component of net periodic benefit cost is included in operating income. All other components are included in other expense, net in the accompanying condensed consolidated statement of income. The components of net periodic benefit cost are as follows:

On October 29, 2018, the Company's board of directors and its compensation committee approved amendments to freeze and terminate the U.S. pension plan and a restoration plan (included in "Other Post-Retirement" in the tables above) as of December 29, 2018. The Company estimates it will incur a curtailment loss in the fourth quarter of 2018 of approximately $1,400,000, which was calculated using actuarial assumptions as of September 29, 2018.
