Business Acquisition, Pro Forma Information [Table Text Block]

The summary below (in millions, except for per share data) presents pro forma unaudited consolidated results of operations for the years ended December 31, 2018 and 2017 as if the acquisition of ECS by the Company and the acquisition of a business by ECS in April 2017, both occurred on January 1, 2017. The pro forma unaudited consolidated results give effect to, among other things: (i) amortization of intangible assets, (ii) stock-based compensation expense and the related dilution for restricted stock units granted to ECS employees, (iii) interest expense on acquisition-related debt and (iv) the exclusion of nonrecurring expenses incurred by ECS prior to its acquisition by the Company for ECS’ acquisition-related activities and costs incurred in the sale of ECS to the Company. The pro forma results do not include pre-acquisition results of DHA or Intersys due to their size. The pro forma unaudited consolidated results are not necessarily indicative of the operating results that would have occurred if the acquisition had been consummated as of the date indicated, nor are they necessarily indicative of future operating results.
