Bob Nail, Avnet Computer Marketing's senior vice president for supply chain management worldwide, resigned on 23 May.
Nail was accused in a lawsuit filed by a former Avnet employee of participating in a scheme to replace Compaq-approved components with cheaper parts for Avnet to increase its margins on every PC it assembled for Compaq.
The extra money would then be used to enhance Avnet Computer Marketing's bottom line each month, according to the lawsuit.
A company spokesman confirmed Nail's departure, but declined to comment on the circumstances surrounding the resignation, citing a company policy on commenting about employee activity.
Nail had worked for Avnet for 28 years.
