Resona in a statement to the Tokyo Stock Exchange said that making Kansai Mirai a wholly owned subsidiary was an option it had considered, but had yet to make any "concrete decision".

Resona, which will announce its results for the three months ended Sept 30 tomorrow, will launch the TOB this month and plans to spend more that 10 billion yen ($96.6 million) to buy all of Kansai Mirai shares, the Nikkei reported.
