azGlover Park is handling communications for AstraZeneca Pharmaceuticals regarding the controversial "inversion" tax dodge issue that has received great play of late due to the wave of European acquisition plays by US companies Pfizer, Walgreen's, Mylan, AbbVie and others.

A successful Pfizer deal for AstraZeneca would have the New York-based company relocate its corporate headquarters in the UK to cut taxes.

AstraZeneca told O'Dwyer's it "has no official policy position on current tax inversion legislation introduced in the US Congress. AstraZeneca has conducted monitoring activities on proposed legislation as the issue of tax inversion continues to generate a lot of attention in the U.S."

Democratic Senators Ron Wyden (OR) and Carl Levin (MI) have been the most vocal critics of the tax dodge.

Levin said US corporations "benefit from the protections and services the federal government provides, including patent protection, research and development tax credits, national security and more; they shouldn’t be allowed to shift their tax burden on to others.”

Wyden said inversions "hollow out the US tax system."

Glover has Joel Johnson, former aide to President Clinton; Jon Gans (ex-member of Sen. Jon Kyl's staff) and Jon Hughes (senior policy member for one-time House Majority Leader Steny Hoyer) working for AstraZeneca.
