Mizuho may decide share sale details this week -sources

TOKYO, June 29 (Reuters) - Mizuho Financial (8411.T), Japan's second-largest bank by assets, may decide as early as this week the details of its planned 600 billion yen ($6.3 billion) share sale, three people familiar with the matter said on Monday.

Mizuho is about to begin preparations for the share sale, said the people, who declined to be identified because the information is not yet public.

A spokeswoman for Mizuho, Masako Shiono, declined to comment.

The bank said in May it planned to raise up to 600 billion through issuing new shares to shore up a balance sheet that has been hit by a recession and losses on its equity holdings. ($1=95.58 Yen) (Reporting by Taro Fuse and David Dolan)
