In this Wednesday, Sept. 17, 2014 photo, Sony Corp. President Kazuo Hirai leaves after a press conference at the company's headquarters in Tokyo. Sony's losses ballooned to 136 billion yen ($1.2 billion) last quarter as the Japanese electronics and entertainment company's troubled mobile phone division reported huge red ink.
