STOCKHOLDERS' EQUITY [Abstract]

Expected option term	3 years	4 years 8 months 12 days
Risk-free interest rate	0.60%	2.10%
Expected forfeiture rate	0.00%	0.00%
Expected dividend yield	0.00%	0.00%

The estimated measure of the percentage by which a share price is expected to fluctuate during a period. Volatility also may be defined as a probability-weighted measure of the dispersion of returns about the mean. The volatility of a share price is the standard deviation of the continuously compounded rates of return on the share over a specified period. That is the same as the standard deviation of the differences in the natural logarithms of the stock prices plus dividends, if any, over the period.
