Bank of America Corporation (BAC.NYSE) may sell some of its US$21 billion stake in China Construction Bank (601939.SH, 0939.HK) to boost its reserves before new international standards come into effect, Bloomberg reported, quoting three people briefed on the plans. Bank of America, the biggest US lender by assets, wants to keep about half of its 25.6 billion shares in CCB and remain a strategic investor in the bank, the world’s second-largest by market capitalization, said two of the sources. The stake equals 10.6% of CCB’s issued shares, according to Bloomberg data. A lockup period, in which Bank of America is prohibited from selling most of its shares in CCB, expires in August. The sale could help Bank of America to comply with the tougher Basel Committee on Banking Supervision requirements currently under consideration, that aim to prevent a repeat of the 2008 financial crisis. CCB’s profits have grown 33% annually since 2007, and its net income is forecast to grow 23% this year, according to analysts surveyed by Bloomberg.
