Note 17: Acquisitions: Business Combinations Policy (Policies)	12 Months Ended
Jun. 30, 2016
Peoples Service Company
Business Combinations Policy	On August 5, 2014, the Company completed its acquisition of Peoples Service Company (PSC) and its subsidiary, Peoples Bank of the Ozarks (Peoples), Nixa, Missouri. Peoples was merged into the Company’s bank subsidiary, Southern Bank, in early December, 2014, in connection with the conversion of Peoples’ data system. The Company acquired Peoples primarily for the purpose of conducting commercial banking activities in markets where it believes the Company’s business model will perform well, and for the long-term value of its core deposit franchise. Through June 30, 2016, the Company incurred $678,000 in third-party acquisition-related costs. Expenses totaling $528,000 are included in noninterest expense in the Company’s consolidated statement of income for the year ended June 30, 2015 and $150,000 for the year ended June 30, 2014 with no comparable expenses in the current period. Notes payable of $2.9 million were contractually required to be repaid on the date of acquisition. The goodwill of $3.0 million arising from the acquisition consists largely of synergies and economies of scale expected from combining the operations of the Company and Peoples. Goodwill from this transaction was assigned to the acquisition of the bank holding company, and is not expected to be deductible for tax purposes.

Disclosure of accounting policy for completed business combinations (purchase method, acquisition method or combination of entities under common control). This accounting policy may include a general discussion of the purchase method or acquisition method of accounting (including for example, the treatment accorded contingent consideration, the identification of assets and liabilities, the purchase price allocation process, how the fair values of acquired assets and liabilities are determined) and the entity's specific application thereof. An entity that acquires another entity in a leveraged buyout transaction generally discloses the accounting policy followed by the acquiring entity in determining the basis used to value its interest in the acquired entity, and the rationale for that accounting policy.
