BASIS OF PRESENTATION

NOTE 1 - BASIS OF PRESENTATION

The significant accounting policies followed by MainSource Financial Group, Inc. (“Company”) for interim financial reporting are consistent with the accounting policies followed for annual financial reporting. The consolidated interim financial statements have been prepared according to accounting principles generally accepted in the United States of America and in accordance with the instructions for Form 10-Q. The interim statements do not include all information and footnotes normally included in the annual financial statements. All adjustments which are, in the opinion of management, necessary for a fair presentation of the results for the periods reported have been included in the accompanying unaudited consolidated financial statements and all such adjustments are of a normal recurring nature. Some items in prior period financial statements were reclassified to conform to current presentation. It is suggested that these consolidated financial statements and notes be read in conjunction with the financial statements and notes thereto in the Company’s Annual Report on Form 10-K for the year ended December 31, 2010.

Adoption of New Accounting Standards

In April 2011, the FASB amended existing guidance for assisting a creditor in determining whether a restructuring is a troubled debt restructuring.  The amendments clarify the guidance for a creditor’s evaluation of whether it has granted a concession and whether a debtor is experiencing financial difficulties.  This guidance is effective for interim and annual reporting periods beginning after June 15, 2011, and should be applied retrospectively to restructurings occurring on or after the beginning of the annual period of adoption.  For purposes of measuring impairment on newly identified troubled debt restructurings, the amendments should be applied prospectively for the first interim or annual period beginning on or after June 15, 2011.  The Company is currently evaluating the impact this guidance will have on its financial statements.

In April 2011, the FASB issued ASU 2011-5 – “Comprehensive Income – Presentation of Comprehensive Income”.  This statement removed the presentation of comprehensive income in the statement of changes in stockholders’ equity.  The only two allowable presentations are below the components of net income in a statement of comprehensive income or in a separate statement of comprehensive income that begins with total net income.  The guidance is effective for interim or annual reporting periods beginning after December 15, 2011.  The Company does not expect the adoption of this guidance to have a material impact on the Company’s results of operations or financial position.
