Amazon came under fire last week after its board opposed a shareholder proposal to increase the diversity of the board. (Update: Amazon announced on Monday that it would adopt the shareholder diversity proposal.) CtW Investment Group, an activist shareholder group, requested that Amazon implement something much like the “Rooney Rule,” a requirement instituted by the NFL in 2003 that every team must interview at least one minority candidate for an open head coach or general manager position. In Amazon’s case, the proposal requires that “the initial list of candidates from which new management-supported director nominees are chosen should include (but need not be limited to) qualified women and minority cand idates.” Currently, all 10 of the directors on Amazon’s board are white, and seven are men.
