Toshiba Corp. may book a loss of over ¥100 billion for the business year through March 2015 as it grapples with a sweeping accounting scandal, sources familiar with the matter said Wednesday.

The recording of the loss would be necessary as Toshiba revaluates its production equipment and other assets held by the semiconductor, house appliance and nuclear power businesses, the sources said.

Toshiba had put its group net profit estimate for fiscal 2014 at ¥120 billion but it could fall into the red due to the huge loss.
