15.	SHARE-BASED PAYMENT

On March 28, 2011, the shareholders and board of directors of the Company approved the 2011 Share Incentive Plan (the “Plan”). The Plan provides for the grant of options, restricted shares and other share-based awards. These options were granted with exercise prices denominated in US$, which is the functional currency of the Company. The board of directors has authorized under the Plan the issuance of up to 12% of the Company's issued and outstanding ordinary shares from time to time, on an as-exercised and fully diluted basis, upon exercise of awards granted under the Plan. The maximum term of any issued share option is ten years from the grant date.

On April 8, 2011, the Company granted 13,864,000 share options to a director and employees with an exercise price of US$0.40 per share.

The aggregate intrinsic value in the table above represents the difference between the fair value of Company's common share as of December 31, 2014 and the exercise price. Total intrinsic value of options granted to employees and directors exercised for the years ended December 31, 2013 and 2014 were RMB53,741 and RMB90,196 (US$14,537), respectively. No share options granted to the employees and directors were exercised during the year ended December 31, 2012. Total intrinsic value of options granted to consultants exercised for the year ended December 31, 2014 was RMB104,416 (US$16,829). No share options granted to the consultants was exercised during the years ended December 31, 2012 and 2013.

On June 8, 2012 (the “Modification Date”), the Company modified the exercise price of both vested and unvested 13,740,000 options that were previously granted to 88 employees, from US$0.4 to US$0.2. The modification was intended to provide additional incentives for these employees.

In accordance with ASC 718, the effects of a modification resulted in incremental compensation cost of US$670, which was measured as the excess of the fair value of the modified award of US$3,460 over the fair value of the original award of US$2,790 at the Modification Date.

The total compensation cost measured at Modification Date was US$2,214, representing the portion of the grant-date fair value of the original award for which the requisite service is expected to be rendered (or has already been rendered) at the Modification Date of US$1,544 and the incremental compensation cost resulting from the modification of US$670.

The incremental compensation cost of US$178 for vested options was recognized immediately at the Modification Date, while the compensation cost of US$2,036 for unvested options is being amortized on an accelerated basis over the remaining vesting term of the original award.

As of December 31, 2014, there was RMB214,038 (US$34,497) of unvested share-based compensation costs related to equity awards granted to employees and directors that is expected to be recognized over a weighted-average vesting period of 2.4 years. To the extent the actual forfeiture rate is different from the original estimate, actual share-based compensation costs related to these awards may be different from the expectation.

As the share options granted to the consultants were fully vested at the grant date, the related compensation expenses were fully recognized in the consolidated statement of comprehensive income at the grant date.

The fair value of share options was determined using the binomial option valuation model, with the assistance from an independent third-party appraiser. The binomial model requires the input of highly subjective assumptions, including the expected share price volatility and the suboptimal early exercise factor. For expected volatilities, the Company has made reference to historical volatilities of several comparable companies. The sub-optimal early exercise factor was estimated based on the vesting and contractual terms of the awards and management's expectation of exercise behavior of the grantees. The risk-free rate for periods within the contractual life of the options is based on market yield of U.S. Treasury Bond in effect at the time of grant. The assumptions used to estimate the fair value of the share options granted are as follows:

	For the years ended December 31
	2012			2013			2014

Expected volatility		50.11	%		49.86	%		50.39%~54.38	%
Risk-free interest rate		1.34	%		2.60	%		0.65%~1.64	%
Dividend yield		0.00	%		0.00	%		0.00	%
Forfeiture rate		0.00	%		0.00	%		0.00%~5.00	%
Suboptimal early exercise factor		2.0			2.2			2.2~2.8

The total fair value of the vested equity awards granted to the employees and directors during the years ended December 31, 2012, 2013 and 2014 were RMB12,437 (US$2,054), RMB11,457 (US$1,893) and RMB 21,946 (US$ 3,537), respectively.

The exercise price of options granted during the years 2013 and 2014, equaled the market price of the ordinary shares on the grant date. No share options were granted during the year ended December 31, 2012. The weighted-average grant-date fair value per share granted to employees and directors during the year ended December 31, 2013, and 2014 were US$0.95 and US$1.35, respectively.
