Sony braced for full-year loss
Sony will report its full-year results later on Thursday, with the Japanese electronics giant having already forecast a loss of $6.4bn (£4bn).
Its bleak performance has seen its share price tumble 40% over the past 12 months to a 25-year low.
Turning the company around will be the top priority for new chief executive Kazuo Hirai, who replaced Howard Stringer at the beginning of April.
