During 1999, China stripped off the non-performing loans of four banks, including Bank of Communications, and handed them over to four specially established financial asset management companies for disposal. These four companies are China Cinda Asset Management Company, China Oriental Asset Management Company, China Huarong Asset Management Company and China Great Wall Asset Management Company. After receiving these non-performing loans, they handled and managed them accordingly. Non-performing loans refer to loans issued by banks or other financial institutions, where the debtor fails to repay the principal and interest within the time limit or the debtor is unable to repay the principal and interest. This kind of loan has the risk of default and may not be fully recovered, so it is classified as "bad". The proportion of non-performing loans is one of the important indicators to measure the risk management ability of banks. The high proportion of non-performing loans may affect the financial situation and operational stability of banks.
