Stockholders' Equity

9. Stockholders’ Equity:

Stock-based compensation:

During the six months ended June 30, 2013, a total of 116,242 options to purchase Common Stock with an aggregate fair market value of approximately $0.3 million were granted to Company employees. The options granted have a term of 10 years from the grant date. The options vest ratably over a three year period. The fair value of each option is amortized as compensation expense evenly through the vesting period. The fair value of each option award is estimated on the grant date using the Black-Scholes valuation model that uses assumptions for expected volatility, expected dividends, expected term, and the risk-free interest rate. Expected volatilities are based on implied volatilities from historical volatility of the Common Stock, and other factors estimated over the expected term of the options. The expected term of options granted is derived using the “simplified method” which computes expected term as the average of the sum of the vesting term plus contract term. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for the period of the expected term. The weighted average for key assumptions used in determining the fair value of options granted during the six months ended June 30, 2013 follows:

Expected price volatility	80.63	%
Risk-free interest rate	0.81	%
Weighted average expected life in years	6 years
Dividend yield	—
