It is due to a number of write-offs the company had to make.
In the first half of the current fiscal year alone (April to September, 2012), Sharp said it made a net loss of 387.5 billion yen as a result of rising restructuring costs and falling demand for LCD televisions.
It booked 84.4 billion yen of extraordinary charges as it wrote off the value of surplus display inventory and pulled out of solar panel manufacturing.
It also wrote off 61 billion yen of so-called deferred tax assets – corporate-tax credits it could redeem if it returned to profit. But that's a prospect that doesn't look good for now.
