Acquisition and Disposition

On September 1, 2013, the Company acquired Summit Bancshares Inc. (Summit). Summit's results of operations are included in the Company's consolidated financial results beginning on that date. The transaction was accounted for using the acquisition method of accounting, and as such, assets acquired, liabilities assumed and consideration exchanged were recorded at their estimated fair value on the acquisition date. In this transaction, the Company acquired all of the outstanding stock of Summit in exchange for shares of Company stock valued at $43.2 million. The Company's acquisition of Summit added $261.6 million in assets (including $207.4 million in loans), $232.3 million in deposits and two branch locations in Tulsa and Oklahoma City, Oklahoma. Intangible assets recognized as a result of the transaction consisted of approximately $13.3 million in goodwill and $5.6 million in core deposit premium. Most of the goodwill was assigned to the Company's Commercial segment. None of the goodwill recognized is deductible for income tax purposes.

On July 25, 2014, the Company sold banking branches in Farmington, Desloge and Bonne Terre, Missouri. The sale included approximately $13.3 million in loans, $60.3 million in deposits, and various bank premises. The Company recognized a $2.1 million gain on the sale.
