On 15 April 2005, the bank acquired Korea First Bank, beating HSBC in the bid. The bank has since rebranded the branches as SC First Bank. Standard Chartered completed the integration of its Bangkok branch and Standard Chartered Nakornthon Bank in October, renaming the new entity Standard Chartered Bank (Thailand). Standard Chartered also formed strategic alliances with Fleming Family & Partners to expand private wealth management in Asia and the Middle East, and acquired stakes in ACB Vietnam, Travelex, American Express Bank (Bangladesh) and Bohai Bank (China). The largest shareholder, Khoo Teck Puat, died in 2004; and two years later, on 28 March 2006, the Singapore state-owned private investment firm, Temasek, became the bank's largest shareholder, when it bought the 11.55% stake held by the estate of billionaire Khoo Teck Puat.
