LONDON -(Dow Jones)- Steel titan ArcelorMittal (MT) expects to sell a significant portion of its $10 billion in minority investments and joint ventures in order to shore up its balance sheet. Chief Financial Officer Aditya Mittal said that management is looking at $10 billion in assets and joint ventures on its balance sheet which could be sold off as a non-core assets in order to reduce net debt and protect its credit rating.
