Toshiba CEO steps down, shares surge on bidding war expectations

Toshiba Corp CEO Nobuaki Kurumatani resigned on Wednesday amid controversy over a $20 billion buyout bid from CVC Capital Partners and the conglomerate's shares surged on reports that KKR & Co and Brookfield are also planning offers.
