What grant of rights means
The ACC is the fourth major conference – joining the Big Ten, Big 12 and Pac-12 – to enter into a grant of media rights agreement. In a grant of rights agreement, schools agree to surrender their television media rights to their conference for the duration of a television contract.
The ACC’s contract with ESPN, which beginning July 1 will pay schools an average of a little more than $20 million per year, runs through the 2026-27 academic year.
The grant of rights extends any time a new TV contract is renegotiated.
If a school left the ACC, its TV rights would remain with the ACC for the duration of the ACC’s TV contract. A departing school would potentially lose hundreds of millions of dollars in TV revenue, and would bring no TV revenue to another conference.
Additionally, any team leaving the ACC still is subject to the exit fee, which is three times the operating cost of the league budget (now more than $50 million).
