(Telecompaper) Sony reported revenues for its fiscal second quarter to September down 10.8 percent year-on-year to JPY 1.689 trillion, hurt by the continued drop in sales of its smartphones. Excluding currency effects, revenues were essentially flat, as the lower mobile sales were offset by growth in financial services and films. Operating profit fell to JPY 45.7 billion from JPY 88.0 billion a year earlier, led by lower results from semiconductors and components, and net profit dropped to JPY 4.8 billion from JPY 33.6 billion. The results include the earlier announced impairment charge on the battery business up for sale and continued repair costs for the earthquake early this year.
