US burger giant McDonald's posted a drop in net income for the fifth consecutive quarter. Sales fell 40% as the group swallowed charges for restructuring at home and was hit by a slump in sales in Asia and Latin America. Net earnings fell to US$271.9m from US$452.0m in the year-ago period. Full-year net earnings plummeted 17% to US$1.64bn, from US$1.98bn in 2000.
