Bank of China (Hong Kong) Limited (BOCHK, 中國銀行(香港)有限公司) is the second-largest commercial banking group in Hong Kong in terms of assets and customer deposits, with more than 300 branches in Hong Kong. It was established on October 1, 2001 from a merger of 12 subsidiaries and associates of the Bank of China in Hong Kong, and listed on the Hong Kong Stock Exchange in October 2002. As of the end of 2003, the bank had HK$763 billion in assets and earned net profit of HK$8 billion in 2003.
BOCHK is one of the three banks which issue banknotes for Hong Kong, the biggest member and a founder of the JETCO ATM and payment system, and the designated clearing bank in Hong Kong for transactions involving the renminbi, Mainland China's currency. It is legally separate from its parent, Bank of China (BOC), although they maintain close relations in management and administration and cooperate in several areas including reselling BOC's insurance and securities services. It also shares its Hong Kong headquarters, the Bank of China Tower, with its parent; completed in 1988, this was the first building outside of North America to exceed 1,000 feet (300 m).
