Stock Option Plan [Abstract]  
Stock Option Plan
Note 15: Stock Option Plan
 
The Company’s Incentive Stock Option Plan (the Plan), which is shareholder approved, permits the grant of stock options to its directors, officers and other key employees. The Plan authorized the grant of options for up to 238,050 shares of the Company’s common stock, which generally vest at a rate of 20 percent a year and have a 10-year contractual term. The Company believes that such awards better align the interests of its directors and employees with those of its shareholders. Option awards are generally granted with an exercise price equal to the market price of the Company’s stock at the date of grant. Certain option awards provide for accelerated vesting if there is a change in control (as defined in the Plans). The Company generally issues shares from its authorized shares to satisfy option exercises.
 
The fair value of each option award is estimated on the date of grant using a binomial option valuation model that uses the assumptions related to expected volatility, expected term of the options awarded and the risk-free rate. Expected volatility is based on historical volatility of the Company’s stock and other factors. The Company uses historical data to estimate option exercise and employee termination within the valuation model. The expected term of options granted is derived from the output of the option valuation model and represents the period of time that options granted are expected to be outstanding. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. No grants were made in 2011 or 2010.
