Toyota said Monday its April-December net profit dived 24 percent but revised up its full-year forecast thanks to foreign exchange gains and a pick-up in sales.

The Japanese auto giant said net profit fell to 1.43 trillion yen ($12.7 billion) in the nine-month period. The company raised its net profit forecast to 1.7 trillion yen for the fiscal year to March, up from its earlier estimate of 1.55 trillion yen.
