Toshiba Corp is set to report an operating loss of more than 10 billion yen ($83 million) in the April-June quarter hurt by weakness in the consumer electronics business, the Nikkei business daily reported. Toshiba last reported a first-quarter loss three years ago, and posted a profit of 47.6 billion yen in the year-earlier quarter, the Nikkei said. Toshiba, which disclosed earlier this year that it overstated past profits, is due to report its delayed April-June results on Monday.
