This case sets out the key financial data on two banks since they went IPO. Ten years ago, China Merchants Bank and ICBC had serious problems with non-performing loans, but since then they have improved considerably. Their income rates increased sharply and their non-performing loans ratios dropped sharply. Net profits rose, which eventually led to a substantial increase in the banks’ ROA and ROE. Through analysis of income and costs, we found that the factors with the greatest impact on performance were income growth and non-performing loans. Regarding income, net interest accounts for 80%, and is clearly affected by the macro environment. Students will consider income and non-performing loans to estimate future prospects and predict ROA and ROE, so as to put a value on each of the banks.
