In a very difficult environment, ArcelorMittal has succeeded in reducing its cost base substantially and significantly strengthening the balance sheet. We therefore start the year in a good position to benefit from the progressive, albeit slow, recovery that is underway. Although 2010 will continue to be challenging, we are now increasing capital expenditure to take advantage of selected growth opportunities as demand improves.
