Acquisitions (Tables)

12 Months Ended

Dec. 31, 2017

The following unaudited pro forma results of operations reflect the 2017 acquisitions as if they had occurred on January 1, 2016 and the 2016 acquisitions as if they had occurred on January 1, 2015. The pro forma information is not necessarily indicative of the results that actually would have occurred, nor does it indicate future operating results. The supplemental pro forma earnings reflect adjustments to earnings from continuing operations as reported in the Consolidated Statements of Earnings to exclude nonrecurring expense related to the fair value adjustments to acquisition-date inventory (after-tax) and acquisition-related costs (after-tax) from the year ended December 31, 2017. These adjustments were not material in 2017. The supplemental pro forma earnings for the 2016 period were similarly adjusted for 2016 acquisitions charges as if incurred at the beginning of 2015. The 2017 and 2016 supplemental pro forma earnings are also adjusted to reflect the comparable impact of additional depreciation and amortization expense, net of tax, resulting from the fair value measurement of tangible and intangible assets relating to 2017 and 2016 acquisitions.
