Mizuho plans to buy out securities, trust units

TOKYO, Feb 26 (Reuters): Mizuho Financial Group is planning to buy out its brokerage and trust bank units, a source familiar with the matter said Saturday, a deal that could be worth around $4 billion as the lender tries to grow beyond sluggish commercial banking business in Japan. Japan's second-largest bank by assets is planning to buy out minority shareholders in Mizuho Securities, Mizuho Trust & Banking, Mizuho Investors Securities, said the source, who was not authorised to talk about the matter publicly. Mizuho is expected to carry out the buyout around October after getting approval at an annual shareholders meeting scheduled in June, the source said.
