What is “Class A” use?

If a commercial is running
on interconnected stations (a network) in more than 21 cities, or sponsors a
program (“This program is brought to you by …”) this constitutes Class A
program use. The cycle begins with the first use date and payments are made on
a declining rate formula for each use occurring within a 13-week period. 

For example, the first Class A use is paid at the same rate as the session
fee. The second use within the 13-week cycle is $130.05 for an on-camera
performer. Uses #3-13 are paid at $103.20 each and the 14th and each use
thereafter is paid at $49.45. ;(Group performers and voice-over performers are
paid under a similar formula, with lower rates reflecting their
classifications). A lower per-use formula applies for use that occurs on PAX
TV.
