Dr. Wentz retired from the position of Board Chairman and director at the Company's Annual Shareholder Meeting on May 1, 2020.

The most significant of these is the Sanoviv Medical Institute, which is a unique, fully integrated health and wellness center located near Rosarito, Mexico that Dr. Wentz founded in 1998. Dr. Wentz’s private entity, Sanoviv S.A. de C.V.

Sanoviv leases the medical building to Amarevita and Amarevita carries out all of the operations of the medical institute, which include employing all of the medical and healthcare professionals who provide services at the medical institute. The Amarevita medical and healthcare professionals possess expertise in the fields of human health, digestive health, nutritional medicine, lifestyle medicine and other medical fields that are important to USANA. Amarevita performs research and development of novel product formulations for future development and production by USANA, and they also perform research and development of improvements in existing USANA product formulations. In addition to providing contract research services, Amarevita provides physicians and other medical staff to speak at USANA Associate events. Finally, Amarevita performs health assessments and physical examinations for the Company’s Executives.

The Company’s agreements with Amarevita were approved by the Audit Committee in advance of the Company’s entry into the agreements. USANA’s collaboration with Amarevita is terminable at will by USANA at any time, without any continuing commitment by USANA.
