OTHER ITEMS IMPACTING COMPARABILITY

Our primary measure of segment performance as shown in Note 19, "Segment Reporting," excludes certain items we do not believe are representative of the ongoing operations of the segment. Excluding these items from our segment measure of performance allows for better year over year comparison:

During the three and six months ended June 30, 2018, the below items were recorded in "Restructuring and other, net":


•	In the second quarter of 2018, we committed to a plan to shutdown our Singapore business operations and recognized employee termination costs of $3 million. We expect to incur additional restructuring charges related to exiting Singapore business operations, but we do not expect these charges to be material to our financial statements.


•	In the second quarter of 2018, we recorded a net restructuring credit of $1 million related to (i) gains on the sale of certain U.K. facilities that were closed as part of our December 2017 restructuring activities and (ii) adjustments to the restructuring accrual recorded as of December 31, 2017, partially offset by professional fees.


•	During the first quarter of 2018, we recorded restructuring and other charges of $0.5 million, primarily related to professional fees and adjustments to the restructuring accrual recorded as of December 31, 2017.


•	During the second quarter and the first half of 2018, we recorded acquisition transaction costs and restructuring charges of $2 million related to the acquisitions of MXD and Metro.


•	During the second quarter of 2017, we realized restructuring credits of $3 million related to the gains on sale of certain U.K. facilities that were closed as part of our December 2016 restructuring activities.

During the first quarter of 2017, we determined that certain operating tax expenses related to prior periods had not been recognized in prior period earnings. We recorded a one-time charge of $2 million within “Selling, general and administrative expenses” in our Consolidated Condensed Statement of Earnings as the impact of the adjustment was not material to our consolidated condensed financial statements in any individual prior period, and the cumulative amount was not material to the first quarter 2017 results.
