Monsanto Co. (MON), the world’s largest seed company worth $64 billion, recently explored a takeover of $34 billion Swiss rival Syngenta AG (SYNN) in a deal that would have allowed the U.S. firm to move its tax location to Switzerland.
The deal, which is now defunct according to people familiar with the matter, is another sign of how U.S. firms in many sectors are trying to avoid corporate taxes by moving their headquarters overseas. U.S. drugmaker Pfizer Inc. pursued U.K.- based AstraZeneca Plc, offering as much as $117 billion before abandoning the deal, while North Chicago, Illinois-based AbbVie Inc. is chasing Dublin-based Shire Plc for $46.5 billion.
