The Belgian company said yesterday that it is looking into "various options for its pharmaceutical activities" including "discussions with third parties." The WSJ estimates that the pharmaceutical division could be worth $6.6 billion and says that potential buyers include Abbott Laboratories, AstraZeneca, Bayer, Merck KGaA of Germany, and Sanofi-Aventis.
