Stock-Based Compensation Plans

7. Stock-Based Compensation Plans.

The Company has two Stock Option Plans (the 2000 Stock Option Plan and the 2006 Stock Option Plan) under which options for shares of common stock were granted to directors, officers and key employees. The 2006 plan permits the grant of stock options, stock appreciation rights, restricted stock awards, restricted stock units, or stock awards. The options awarded under the plans have similar characteristics. All stock options are non-qualified and expire ten years from the date of grant. Stock based compensation awarded to directors, officers and employees are exercisable immediately or become exercisable in cumulative installments of 20% or 25% at the end of each year following the date of grant. When stock options are exercised the Company issues new shares after receipt of exercise proceeds and taxes due, if any, from the grantee. The number of common shares available for future issuance was 537,880 at September 30, 2013.

The Company utilizes the Black-Scholes valuation model for estimating fair value of stock compensation for options awarded to officers and employees. Each grant is evaluated based upon assumptions at the time of grant. The assumptions were no dividend yield, expected volatility between 37% and 46%, risk-free interest rate of .3% to 4.2% and expected life of 3.0 to 7.0 years.

The dividend yield of zero is based on the fact that the Company does not pay cash dividends and has no present intention to pay cash dividends. Expected volatility is estimated based on the Company’s historical experience over a period equivalent to the expected life in years. The risk-free interest rate is based on the U.S. Treasury constant maturity interest rate at the date of grant with a term consistent with the expected life of the options granted. The expected life calculation is based on the observed and expected time to exercise options by the employees.

The Company recorded the following stock compensation expense in its consolidated statement of income (in thousands):
