Pro forma information of acquiree  
The following unaudited supplemental pro forma data presents consolidated information as if the acquisition had been completed on November 1, 2017. These amounts were calculated after adjusting Caraustar's results to reflect interest expense incurred on the debt to finance the acquisition, additional depreciation and amortization that would have been charged assuming the fair value of property, plant and equipment and intangible assets had been applied from November 1, 2017, the adjusted tax expense, and related transaction costs of $35.2 million. These adjustments also include an additional charge of $9.0 million in the six month period ended April 30, 2018 for the fair value adjustment for inventory acquired.
