Temasek Holdings Pte, Singapore’s state investment company, bought Bank of America Corp.’s share of China Construction Bank Corp.’s US$9.2 billion ($11.8 billion) rights offer, spokesman Jeffrey Fang said.

Bank of America, Construction Bank’s largest private shareholder, won’t participate in the offering, two people with knowledge of the matter said, declining to be identified. Fang, a Singapore-based spokesman for Temasek, didn’t say how much the company’s stake in Construction Bank will increase as a result of the transaction.

Beijing-based Construction Bank, the world’s second-largest lender by market value, said on Nov. 1 it will offer existing investors 0.7 share for every 10 held at 3.77 yuan ($0.73) each in Shanghai and HK$4.38 ($0.73) in Hong Kong.

Bank of America owns 25.58 billion shares in Construction Bank, or 10.95%, trailing only the Chinese government’s 57% stake, Construction Bank said last week. Temasek is the bank’s third-biggest investor with a 5.65% stake.

Central Huijin Investment Co., which owns stock in Construction Bank on behalf of the Chinese government, has committed to participating in the rights offer.

Reuters reported earlier today that Temasek will purchase Bank of America’s rights, citing people it didn’t identify.
