A compensation consultant to Best Buy’s board quit after the electronics chain awarded more than 100 managers retention bonuses without tying them to performance, said three people with knowledge of the matter.

Don Delves, who worked with Best Buy’s compensation committee for seven years as an independent consultant, was opposed to the payments, said the people, who asked not to be identified because the situation is private. Delves, president of Delves Group, a corporate governance and an executive pay advisory firm, confirmed in a telephone interview that he resigned this month.

Chief Financial Officer James Muehlbauer and Michael Vitelli, head of the US division, were among executives awarded extra pay as incentive to stay while Best Buy seeks a replacement for former CEO Brian Dunn, a June regulatory filing shows.

Dunn, 52, resigned in April amid revelations that he had an inappropriate relationship with a female employee.
