Number of shares
Weighted average number of ordinary share outstanding- basic and diluted	387,517,503	401,602,159	418,314,541


Basic net (loss) earnings per share	0.00	0.01	(0.1	)
Diluted net (loss) earnings per share	0.00	0.01	(0.1	)

For the year ended December 31, 2015, diluted loss per share are the same as basic loss per share as the Company did not have any equity instruments that have dilutive effect on loss per share during the periods presented.

For the year ended December 31, 2016 and 2017, diluted net income (loss) per share does not include the 330,000 share options, of which the exercise price is higher than the average market price, as their inclusion would be anti-dilutive.

For the year ended December 31, 2016, diluted net income (loss) per share does not include the 330,000 share options, of which the exercise price is higher than the average market price, or 1,430,000 unvested restricted shares, of which assumed exercise price is higher than the average market price for year ended December 31, 2016, as their inclusion would be anti-dilutive.

For the year ended December 31, 2017, diluted net income (loss) per share does not include the 220,000 share options, of which the exercise price is higher than the average market price, or 940,000 unvested restricted shares, of which assumed exercise price is higher than the average market price for year ended December 31, 2017, as their inclusion would be anti-dilutive.

The following potential ordinary shares are anti-dilutive and are therefore excluded from the weighted average number of ordinary shares for the purpose of diluted loss per share.
