ArcelorMittal Buys 61.7 Million Call Options on Its Own Shares

Following the reopening of its share buy-back program as announced on 26 November 2010, ArcelorMittal MT acquired on 14 December 2010 euro-denominated call options on 61,728,395 of its own shares with a strike price of EUR 20.25 per share. The 61.7 million of call options acquired allow ArcelorMittal to hedge its obligations arising primarily out of the potential conversion of the 7.25% bonds convertible into and/or exchangeable for new or existing ArcelorMittal shares due 1 April 2014 and secondarily under the share-based employee incentive plans of the group.
