How long is a performer “held” to a commercial?

The “maximum
period of use” of a commercial is 21 months (a total of seven 13-week holding
fee cycles). Provided the producer continues to make timely holding fee
payments, the performer is held exclusive to the product for the 21-month
period. If the performer (or his/her representative) does not send a timely
renegotiation letter, the producer can extend the maximum period of use for an
additional 21 months at the same rates as for the original 21 months.
