[1] As part of our review of costs included in the corporate segment, amounts related to division operations were identified and reclassified out of other (expense) income, net to cost of sales. The impact for the three and nine months ended September 30, 2017 was $2.1 million and $5.3 million, respectively.

[2] Due to the adoption of ASU 2017-07, certain amounts related to defined benefit and other post-employment benefit plans were reclassified from cost of sales to other (expense) income, net.
