Business Acquisition, Pro Forma Information [Table Text Block]

The following table provides unaudited pro forma total revenues and results of operations for the 12 months ended December 31, 2017 and 2016 as if ARI had been acquired on January 1, 2016. The unaudited pro forma results reflect certain adjustments related to the acquisitions, such as a step-up in basis in inventory, amortization expense on intangible assets arising from the acquisition, and interest on the acquisition financing. The pro forma results do not include any anticipated cost synergies or other effects of any planned integration. Accordingly, such pro forma amounts are not necessarily indicative of the results that actually would have occurred had the acquisitions been completed at the beginning of 2016, nor are they indicative of the future operating results of the combined companies.
