Hancock, who is the managing partner of Claiborne Farm, has been a CDI director since 1973.
“For the past 30-plus years, I have enjoyed being a part of one of Thoroughbred racing’s premiere racing companies,” said Hancock in a CDI release. “But after more than three decades of service, it’s time for me to move on and embrace new challenges. I look forward to CDI’s continued innovation and success for the benefit of our entire industry.”
The release said Hancock’s announcement was effective June 19, the day of the CDI annual meeting with shareholders.
CDI board chairman Carl F. Pollard praised Hancock’s contributions to the company.
“Seth Hancock has served the board with great distinction for many years, and his leadership will be missed,” he said in the release. “We have relied on his counsel and wisdom on a great many issues related to our company and the industry as a whole. Personally, I wish him the very best in his future endeavors.”
Hancock, 58, is also president of Hancock Farms, a director of Keeneland Association and Hopewell Company, and a trustee of the Thoroughbred Owners and Breeders Association.
