Amortization of net loss					$ 959

[1] The amortization of net loss during the nine months ended September 30, 2016 includes a $959 charge resulting from the deconsolidation of the Venezuelan subsidiary.

[2] Pension settlement charges resulting from lump sum pension payments in the three and nine months ended September 30, 2017.

[3] The increase for the three and nine months ended September 30, 2017 as compared to the prior year periods reflect pension settlement charges and higher defined contribution plan expense related to the Company's amended U.S. defined contribution plan that was effective January 1, 2017, partially offset by lower service cost and lower amortization of net losses related to the defined benefit plan freeze effective December 31, 2016.
