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, 2011.

Adoption of New Accounting Standards

In May, 2011, the FASB issued an amendment to achieve common fair value measurement and disclosure requirements between U.S. and International accounting principles. Overall, the guidance is consistent with existing U.S. accounting principles; however, there are some amendments that change a particular principle or requirement for measuring fair value or for disclosing information about fair value measurements.  The amendments in this guidance are effective for interim and annual reporting periods beginning after December 15, 2011.  The effect of adopting this standard did not have a material effect on the Company’s operating results or financial condition, but the additional disclosures are included in Note 8.

In June 2011, the FASB amended existing guidance and eliminated the option to present the components of other comprehensive income as part of the statement of changes in shareholder’s equity. The amendment requires that comprehensive income be presented in either a single continuous statement or in two separate consecutive statements. The amendments in this guidance are effective as of the beginning of a fiscal reporting year, and interim periods within that year, that begins after December 15, 2011. The adoption of this amendment has changed the presentation of the components of comprehensive income for the Company as part of the consolidated statement of comprehensive income.
