ArcelorMittal takes $4.3 billion write-down on weak Europe By Ben Deighton BRUSSELS (Reuters) - ArcelorMittal (ISPA.AS), the world's biggest steelmaker, is writing down the value of its European business by $4.3 billion, underscoring its gloom about prospects for the region's recession-hit manufacturers. The group, formed in 2006 when the steel business of India-born Lakshmi Mittal bought Europe's Arcelor for about $33 billion, said on Friday steel demand had fallen about 8 percent in Europe this year and there was no sign of a quick recovery. As a result, it was writing down the goodwill - the value of intangible assets like a brand rather than physical assets like machinery - of its European operations by 87 percent. "It is negative, but it shouldn't really be a big surprise that the book value of its European business was too high," said a London-based analyst who asked not to be named. At 5:45 a.m. ET, ArcelorMittal shares were down 2.9 percent at 7.74 euros, one of the biggest falls by a European blue chip stock .FTEU3 and reversing gains made earlier this week. The $500-billion-a-year steel industry, a gauge of the global economy, has slowed sharply this year from last as a moderation in China's economic growth has compounded weak demand from austerity-ravaged Europe. The World Steel Association in October forecast steel demand would rise by 2.1 percent in 2012, down from 6.2 percent in 2011. It had forecast 3.6 percent growth in April. Other steelmakers are hurting too. Earlier this month, Germany's ThyssenKrupp (TKAG.DE) posted an annual net loss of 4.7 billion euros ($6.2 billion). Europe is a particular weak point, as austerity drives aimed at tackling a sovereign debt crisis have cut demand for construction and cars, the steel sector's largest markets. The euro zone's manufacturing sector has contracted for 17 straight months. ArcelorMittal, which makes about 6-7 percent of the world's steel, said steel demand in Europe had fallen about 29 percent since 2007, when the financial crisis started. But it highlighted better trends in the United States, where it said demand was up almost 8 percent this year and is now about 10 percent lower than in 2007. ArcelorMittal, whose output is more than double that of its nearest rival, has already announced the closure of blast furnaces in France and Belgium, with other operations temporarily idled due to overcapacity. The write-down represents over a third of ArcelorMittal's overall goodwill of $12.5 billion reported at the end of last year. The group, around 40-percent owned by the Mittal family, took on about $6.6 billion of goodwill when it bought Arcelor. It said the write-down would be a non-cash charge in its fourth quarter results and would not affect net debt or core profit. Before the write-down, analysts had on average forecast the group would make $529.5 million in net profit this year, and $7.1 billion in core profit, according to StarMine.
