[1] During the fourth quarter of 2018, the Company recorded a $12.5 million pre-tax adjustment to correct errors that occurred from 2016 through the third quarter of 2018 with respect to the accounting for certain long-term contracts in one of the Company’s CPS divisions. These errors are immaterial to all prior periods. The impact of this out-of-period adjustment on the full year fiscal 2018 was $11 million which is also immaterial to 2018.
