ƒ In Western Europe, positive UK volume trends and strong cost reduction only partially offset the impact of the steep volume declines in Greece and Spain. In Q4, poor weather and fewer carbon credit sales lowered results. ƒ North America volume recovery and cost containment supported earnings growth for both the FY and Q4. ƒ Central and Eastern Europe results were impacted by difficult economic conditions in Romania and lower prices in Poland. Market trends in Russia and Poland improved in the second half, although harsh weather and fewer carbon credit sales weighted on Q4 results. ƒ MEA market trends were positive but results were lower for the year due to the entrance of new capacities (Jordan) and production shortfalls (Algeria). Q4 volumes returned to growth and current operating income benefited from the reversal of a regulatory fee on raw materials in Egypt. ƒ Latin America grew due to dynamic market trends and newly integrated Brazil assets. ƒ Asia earnings declined due to lower prices in South Korea and China, compounded by rising costs.
