22. SHARE OPTIONS

        On May 30, 2006, the Board of Directors approved the adoption of a share incentive plan to provide additional incentives to employees, directors or external consultants. The maximum aggregate number of shares which may be issued pursuant to all awards (including options) is 2,330,000 shares, plus for awards other than incentive option shares, an annual increase to be added on the first business day of each calendar year beginning in 2007 equal to the lesser of one percent (1%) of the number of common shares outstanding as of such date, or a lesser number of common shares determined by the Board of Directors or a committee designated by the Board. In September 2010, the shareholders approved an amendment to the Plan to increase the maximum number of common shares which may be issued pursuant to all awards of options and restricted shares under the Plan to the sum of (i) 2,330,000 plus (ii) the sum of 1% of the number of outstanding common shares of the Company on the first day of each of 2007, 2008 and 2009 and 2.5% of the number of outstanding common shares of the Company outstanding on the first day of each calendar year after 2009. The share incentive plan will expire on, and no awards may be granted after, March 15, 2016. Under the terms of the share incentive plan, options are generally granted with an exercise price equal to the fair market value of the Company's ordinary shares and expire ten years from the date of grant.

Options to Employees

        As of December 31, 2011, there was $9,378,964 in total unrecognized compensation expense related to share-based compensation awards, which is expected to be recognized over a weighted-average period of 2.9 years. During the years ended December 31, 2009, 2010 and 2011, $5,025,225, $3,641,260 and $3,382,786 was recognized as compensation expense, respectively. There is no income tax benefit recognized in the income statement for the share-based compensation arrangements in 2009, 2010 and 2011.

        The Company utilizes the Binomial option-pricing model to estimate the fair value of stock options.

        The following assumptions were used to estimate the fair value of stock options granted in 2009, 2010 and 2011:

 
   2009   2010   2011

Risk free rate

   4.67% ~ 5.72%   4.25% ~ 4.75%   2.76% ~ 3.46%

Volatility ratio

   81% ~ 84%   80% ~ 84%   77% ~ 79%

Dividend yield

   —   —   —

Annual exit rate

   3.56% ~ 5.24%   2.89% ~ 3.36%   3.07% ~ 4.37%

Exercise multiple

   5.40 ~ 6.20   5.00   4.40 - 4.70

        The Company used the market yield of USD dominated Chinese International government bonds with maturity periods that can cover the contractual life of the shares option for the risk-free rates. The Company estimated the expected volatility based on the average of historical daily annualized volatility of its own and comparable companies' stock prices. The Company's dividend policy is to retain earnings for reinvestment purpose and the Company does not intend to distribute dividends, thus the dividend yield is assumed to be zero. The Company estimated the annual exit rates based on the historical general exit rate of staff at different levels. The Company estimated the exercise multiple based on the historical exercise pattern of prior employee stock options granted by the Company.

The restricted shares were granted at nominal value and generally vest over periods from one to four years based on the specific terms of the grants. The difference between the exercise price of the restricted shares and the fair market value of the Company's ordinary shares at the date of grant resulted in total compensation cost of approximately $7.1 million that will be recognized ratably over the vesting period. During the years ended December 31, 2009, 2010 and 2011, the Company recognized $411,125, $235,411 and $nil in compensation expense associated with these awards, respectively.

Restricted shares units to Employees

        The Company granted 475,313 and 42,868 restricted shares units ("RSU") to employees in May 2011 and July 2011, respectively. The RSUs entitle the holders to receive the Company's common shares upon vesting. The RSU were granted for free and generally vest over periods from one to four years based on the specific terms of the grants. The fair market value of the Company's ordinary shares at the date of grant resulted in total compensation cost of approximately $4.6 million that will be recognized ratably over the vesting period. During the year ended December 31, 2011, the Company recognized $678,052 in compensation expense associated with these awards.

        As of December 31, 2011, there was $3,897,651 of total unrecognized share-based compensation related to unvested restricted share units, which is expected to be recognized over a weighted-average period of 3.3 years.
