• (3) The decline of the sales price of the Group's self-produced coal products resulted in a decrease of RMB890 million in the net profit attributable to the equity holders of the Company in the first half year of 2013 as compared to that in the Previous Results Estimate.

The comprehensive average sales price of the Company's self-produced coal products in the first quarter of 2013 was RMB550.34 per ton. The comprehensive average sales price in the second quarter of 2013 was estimated to be RMB533.65 per ton in the Previous Results Estimate.
