3. Based on preliminary examination by the certified public accountants, the interest payable of the US$300 million perpetual capital securities issued by Yancoal International Trading Co., Limited, a wholly-owned subsidiary of the Company, in the year of 2014 was RMB 82 million, which is expected to be paid from retained earnings, and led to a downward adjustment in the net profit attributable to shareholders of the Company in 2014.
