The table above includes many financial data which can be used to analyze the financial situation of the miner. Firstly, net profit before tax compared to sales and total assets changed respectively from 34.6% to 20.1% and 18.2% to 11.1% from 2010 to 2011, those ratios all decreased sharply and mean that the net profit margin and return on total assets all fell substantially. As a result, total comprehensive income that consists of net income and other items bypassing the net income rather than net profit is more suitable for investors to take into account
