Pfizer, the maker of best-selling drugs like Lipitor and Viagra and a symbol of business prowess in the United States for more than a century, no longer wants to be an American company.
On Monday, Pfizer proposed a $99 billion acquisition of its British rival AstraZeneca that would allow it to reincorporate in Britain. Doing so would allow Pfizer to escape the United States corporate tax rate and tap into a mountain of cash trapped overseas, saving it billions of dollars each year and making the company more competitive with other global drug makers.
