As of December 31, 2012, there was no options outstanding.

The total intrinsic value of share options exercised for the twelve months ended December 31, 2012 and 2011 were approximately US$Nil and US$Nil, respectively. As of December 31, 2012 there was no unrecognised stock-based compensation expense related to unvested stock options.

The Group adopted the provisions of ASC 718-10, which requires us to recognise expense related to the fair value of our stock-based compensation awards, including employee stock options.

The Black-Scholes option-pricing model is used to estimate the fair value of the options granted. This requires the input of subjective assumptions, including the expected volatility of stock price, expected option term, expected risk-free rate over the expected option term and expected dividend yield rate over the expected option term. Because changes in subjective input assumptions can materially affect the fair value estimate, in directors’ opinion, the existing model may not necessarily provide a realisable measure of the fair value of the stock options. Expected volatility is based on historical volatility in the 180 days prior to the issue of the options. Expected option term and dividend yield rate are based on historical trends. Expected risk-free rate is based on US Treasury securities with similar maturities as the expected terms of the options at the date of grant.
