Unlike other conferences such as the Big East ( which required a 27-month notification period before a member could leave ) and the ACC ( which imposes a substantial exit fee to departing members , equal to three times the ACC 's operating budget or around $ 50 million ) , the SEC allows members to voluntarily leave the conference at will , with no exit fees . In addition , whereas a major point of contention within the Big 12 was the unequal distribution of revenue among member schools , the SEC distributes television revenues generally equally among member schools ( with slightly higher allocations for schools participating in bowl games and the NCAA men 's basketball tournament )
