Electronics giants Sony have announced weakened results for the final quarter of 2011.
The company reported a net loss of 159 billion yen ($2.1 billion; £1.3 billion) for the final three months of 2011, compared with a profit of 72bn yen a year earlier, citing lower production following floods in Thailand.
