Agricultural Bank of China Limited ( ABC , simplified Chinese : 中国农业银行 ; traditional Chinese : 中國農業銀行 ; pinyin : Zhōngguó Nóngyè Yínháng ), also known as AgBank or 农行 Nóngháng , is one of the " Big Four " banks in the People's Republic of China . It was founded in 1951, and has its headquarters in Dongcheng District , Beijing .  It has branches throughout mainland China , Hong Kong , London , Tokyo , New York , Frankfurt , Sydney , Seoul , and Singapore .
ABC has 320 million retail customers, 2.7 million corporate clients, and nearly 24,000 branches. It is China's third largest lender by assets. ABC went public in mid-2010, fetching the world's biggest ever initial public offering (IPO) at the time,  since overtaken by another Chinese company, Alibaba.  As of 2011, it ranks 8th among the Top 1000 World Banks,  meanwhile In 2015, it ranks 3rd in Forbes’ 13th annual Global 2000 ranking of the biggest, most powerful and most valuable companies in the world. 
Since the establishment of the People's Republic of China in 1949, ABC has been formed and abolished several times. In 1951, two banks of the Republic of China , Farmers Bank of China and Cooperation Bank, merged to form the Agricultural Cooperation Bank, which ABC regards as its ancestor. However, the bank was merged into People's Bank of China , the central bank in 1952. The first bank bearing the name Agricultural Bank of China was founded in 1955, but it was merged into the central bank in 1957. In 1963 the Chinese government formed another agricultural bank which was also merged into the central bank two years later. Today's Agricultural Bank of China was founded in February 1979. It was restructured to form a holding company called Agricultural Bank of China Limited.  It was listed on the Shanghai and Hong Kong stock exchanges in July 2010. 
In April 2007, ABC was the victim of the largest bank robbery in Chinese history . This occurred when two vault managers at the Handan branch of the bank in Hebei province embezzled almost 51 million yuan ( US$ 7.5 million). 
2010 initial public offering
ABC was the last of the " big four " banks in China to go public. In 2010, A shares and H shares of Agricultural Bank of China were listed on the Shanghai Stock Exchange and the Hong Kong Stock Exchange respectively. Each share was set to cost between 2.7 RMB and 3.3RMB per share.  H shares were set to cost between HK$2.88 and HK$3.48 per share.  The final share price for the IPO launch was issued on July 7, 2010. On completion in August 2010 it became the world's biggest initial public offering (IPO) surpassing the one set by Industrial and Commercial Bank of China in 2006 of US$21.9 billion .  This record has since been beaten by another Chinese company, Alibaba, in 2014. 
ABC raised US$19.21 billion in an IPO in Hong Kong and Shanghai on July 6, 2010, before overallotment options were exercised.  On August 13, 2010, ABC officially completed the world's largest initial public offering, raising a total of $22.1 billion after both Shanghai and Hong Kong's over-allotments were fully exercised.   The IPO was once thought to be able to raise US$30 billion , but weaker market sentiment dampened the value.  Despite a 15-month low for the Chinese benchmark index, the IPO was said to have gone smoothly. 
CICC , Goldman Sachs , and Morgan Stanley led the Hong Kong offering, with JPMorgan , Macquarie , Deutsche Bank and ABC's own securities unit also involved. CICC , Citic Securities , Galaxy and Guotai Junan Securities handled the Shanghai portion. ABC sold about 40% of the Shanghai offering to 27 strategic investors including China Life Insurance and China State Construction . They were subject to lock-up periods of 12–18 months. Eleven cornerstone investors were selected for its Hong Kong share offering, including Qatar Investment Authority and Kuwait Investment Authority , taking a combined $5.45 billion worth of shares .
