On Friday, world's largest steelmaker ArcelorMittal (MT 0.15%) announced that in accordance with the results of its annual "goodwill impairment test," it expects to take a $4.3 billion goodwill writedown on its European businesses in Q4.

The impairment, a non-cash charge to earnings, is almost certain to result in a quarterly loss for the steelmaker, which has only once in its history  (in Q2 of 2008) earned more than $4.3 billion in a single quarter. Arcelor explained the charge by pointing to an 8% decline in "apparent steel demand" in Europe this year, a decline that it says has run to approximately 29% in comparison with 2007 demand.

On a brighter note, Arcelor said that its U.S. operations are performing better, with an aggregate 10% fall in demand since 2007, but an 8% increase in steel demand so far this year.

Shares of ArcelorMittal are down 3.6% on the news at $16.89.
