US agribusiness giant Bunge has reported fourth-quarter net profit of $97m, compared to $48m in the year-ago period, beating both its own forecasts and analysts' estimates. Bunge, which back in December raised its fourth-quarter earnings estimate to between $80m and $90m, benefited from record harvests and weaker currencies in South America during the quarter. The company's original forecast was for earnings of between $55m and $60m.
