Summary of weighted-average assumptions used for determining the fair value of each stock option granted

 

 

Assumptions:

       

Expected dividend yield(1)

    N/A  

Expected stock price volatility(2)

    77.4 %

Risk-free interest rates(3)

    1.36 %

Expected term of options (in years)(4)

    6.00  

(1)
The expected dividend yield was based on our expectation of not paying dividends for the foreseeable future.

(2)
The expected volatility was based on the historical volatility of our common stock.

(3)
Based on the U.S. Treasury yield curve in effect at the time of grant with a term consistent with the expected term of our stock options.

(4)
Represents the period of time options are expected to be outstanding. The weighted average expected term was determined using the "simplified method" for plain vanilla options as the Company lacks sufficient historical exercise experience. The "simplified method" calculates the expected term as the average of the vesting term and original contractual term of the options.
