Huntsman said Tuesday it also will assume $225 million in unfunded pension liabilities as part of the acquisition of performance additives and titanium dioxide businesses from Rockwood Holdings.
Texas-based Huntsman said it expects the deal to add about 60 cents per share to its annual earnings. It also said the purchase will give it a broader product range that includes color pigments, functional additives and specialty titanium dioxide pigments.
