Apple holds a farewell party for outgoing CEO Tim Cook at Apple Park, with OneRepublic performing as part of the event. The gathering takes place on August 23, drawing about 200 people, according to reports from multiple outlets.

The date is tied to Cook’s tenure: he became CEO 15 years ago on August 23 and is scheduled to step down as CEO on September 1. While Cook leaves the CEO role, Apple says he remains with the company as executive chairman. The Information and other outlets also note he continues in an executive liaison capacity.

Other coverage adds detail on the tributes and attendees. Times of India reports that Apple includes remarks from senior leaders such as Jeff Williams and Eddy Cue, as well as tributes from Laurene Powell Jobs. Apple’s successor, John Ternus, is also referenced as taking over as CEO on September 1, after Cook’s 15-year leadership.
