The Japanese electronics and entertainment company also dragged itself back to profit for the fiscal year ended March 31, following four straight years of red ink.
It reported today annual earnings of USD 434 million, a reversal from a loss of USD 5.7 billion the previous year the worst in the company's nearly seven-decade history.
Tokyo-based Sony expects the recovery to continue, and projected a USD 505 million profit for the fiscal year through March 2014, up 16 per cent.
The favourable exchange rate is expected to continue in the coming months because of the policies of Prime Minister Shinzo Abe, who took office last year.
