Pharmaceutical company Allergan has elected John Davidson to its board of directors. Davidson and the other directors standing for re-election to Allergan's board were elected at Allergan's Annual General Meeting of Shareholders on May 2.

Davidson retired from Tyco International in 2012, having served as senior vice president, controller, and chief accounting officer. He was responsible for overseeing financial reporting, internal controls, and accounting policies and processes. He joined Tyco in 2004, working as part of the new senior leadership team in establishing financial integrity, operational excellence and strong ethical practices across Tyco global operations. Since 2012, Davidson has served on the board of governors of the Financial Industry Regulatory Authority (FINRA), which regulates and oversees the U.S. financial industry.

With the addition of Davidson, and the previously announced retirement of directors James Bloem and Ronald Taylor, the Allergan board now has 12 members.
