Stock Option Plans

At March 31, 2013, the Company had one equity incentive plan, the 2005 Equity Incentive Plan (“2005 Equity Plan”). The 2005 Equity Plan, as amended, authorizes for issuance as stock options, stock appreciation rights, or stock awards an aggregate of 3,250,000 new shares of common stock to employees, directors or consultants. The total plan reserve includes these new shares and shares reserved under prior plans, allowing for the issuance of up to 4,999,564 shares. At March 31, 2013, there were options outstanding covering 3,020,139 shares of common stock under the 2005 Equity Plan and an additional 1,388,477 shares of common stock available for grant.

The employee stock options granted in the six months ended March 31, 2013 and 2012 had a weighted-average estimated fair value of $.70 per share and $1.07 per share, respectively, using the Black-Scholes option pricing model with the following weighted-average assumptions (annualized percentages):

 

                 
    Six months ended
March 31,		  
    2013     2012  

Volatility

     81.0 %      82.0 % 

Risk-free interest rate

     0.9 %      1.10 % 

Forfeiture rate

     10.0 %      10.0 % 

Dividend yield

     0.0 %      0.0 % 

Expected life in years

     6.4       6.4  

The Company has never paid cash dividends and has no present intention to pay cash dividends. Expected volatility is based on the historical volatility of the Company’s common stock over the period commensurate with the expected life of the options. The risk-free interest rate is based on rates published by the Federal Reserve Board. The expected life is based on observed and expected time to post-vesting exercise. The expected forfeiture rate is based on past experience and employee retention data. Forfeitures are estimated at the time of the grant and revised in subsequent periods if actual forfeitures differ from those estimates or if the Company updates its estimated forfeiture rate. Such amounts will be recorded as a cumulative adjustment in the period in which the estimate is changed.

Since the Company has an NOL carryforward as of March 31, 2013, no excess tax benefit for the tax deductions related to share-based awards was recognized for the six months ended March 31, 2013 and 2012. As of March 31, 2013, there was approximately $700,000 of total unrecognized compensation cost related to non-vested share-based employee compensation arrangements. The cost is expected to be recognized over a weighted-average period of 1.3 years.
