TOKYO (Reuters) - Toshiba Corp said on Tuesday that it expects to book an impairment loss on the acquisition of a U.S. nuclear power business by its Westinghouse unit, a figure that could reach several billions of dollars. The Japanese conglomerate said it planned to book several billions of dollars in goodwill related to the purchase of CB&I Stone and Webster but added that was seeking to determine if it should write down the entire value of goodwill or just part of it.
