Summary of Accounting Policies

2. Summary of Accounting Policies

The Company is a bank financial holding company, which offers a wide range of banking and other financial services to its customers through its branches and offices in the states of Missouri, Kansas, Colorado, Illinois, Oklahoma, Arizona, Nebraska, Pennsylvania, South Dakota, Indiana, Utah, and Wisconsin. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. These estimates and assumptions also impact reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. A summary of the significant accounting policies to assist the reader in understanding the financial presentation is listed in the Notes to Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2012.

Per Share Data

Basic income per share is computed based on the weighted average number of shares of common stock outstanding during each period. Diluted income per share includes the dilutive effect of 418,210 and 347,396 shares issuable upon the exercise of stock options granted by the Company at March 31, 2013 and 2012, respectively.

Options issued under employee benefit plans to purchase 280,611 and 632,533 shares of common stock were outstanding at March 31, 2013 and 2012, respectively, but were not included in the computation of diluted EPS because the options were anti-dilutive.
