(Telecompaper) Net income plunged 88.8 percent to JPY 30.5 billion in the quarter, due mainly to financial and derivative losses related to the company's stake in Alibaba. Operating income amounted to JPY 479.2 billion, which represents an increase of 50.1 percent year-on-year, due largely to the inclusion of the new Softbank investment fund. Excluding the Softbank Vision Fund, operating profit was up 17.2 percent to JPY 374.0 billion, led by growth at Sprint and Yahoo Japan.
