(the "Company") in accordance with accounting principles for interim financial information generally accepted in the United States and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes necessary for a comprehensive presentation of financial position and results of operations. It is management’s opinion, however, that all material adjustments (consisting of normal recurring accruals) have been made which are necessary for a fair statement of its financial position, results of operations and cash flows.

Definitive Transaction Agreement with Amcor On August 6, 2018, the Company announced that its Board of Directors, along with the Board of Directors of Amcor Limited (“Amcor”), unanimously approved a definitive agreement (the "Agreement”) under which Bemis will combine with Amcor in an all-stock combination (the “Transaction”). The Transaction will be effected at a fixed exchange ratio of 5.1 Amcor shares for each share of the Company, resulting in Amcor and Bemis shareholders owning approximately 71% and 29% of the combined company, respectively. Closing of the Transaction is conditional upon the receipt of regulatory approvals, approval by both Amcor and Bemis shareholders, and satisfaction of other customary conditions. The Agreement contains certain termination rights for both Bemis and Amcor, including if the Transaction is not completed on or before August 6, 2019, subject in certain circumstances to extension to February 6, 2020 if necessary to secure certain regulatory approvals. The Agreement provides that Bemis will pay a $130 million termination fee to Amcor if, among other things, Bemis terminates the Agreement to enter into a superior proposal or if the Agreement is terminated following Bemis’s Board of Directors changing its recommendation or failing to publicly affirm the board recommendation after receipt of a competing proposal. The Agreement also provides that Amcor will pay a $130 million termination fee to Bemis under similar circumstances. In the first quarter of 2019, in connection with the Transaction, the Company incurred pre-tax expenses of approximately $2.9 million related to professional fees which are recorded in Restructuring and other costs in the condensed consolidated statement of income.
