47 CFR § 76.1611 - Political cable rates and classes of time.
If a system permits a candidate to use its cablecast facilities, the system shall disclose to all candidates information about rates, terms, conditions and all value-enhancing discount privileges offered to commercial advertisers. Systems may use reasonable discretion in making the disclosure; provided, however, that the disclosure includes, at a minimum, the following information:
(a) A description and definition of each class of time available to commercial advertisers sufficiently complete enough to allow candidates to identify and understand what specific attributes differentiate each class;
(b) A description of the lowest unit charge and related privileges (such as priorities against preemption and make goods prior to specific deadlines) for each class of time offered to commercial advertisers;
(c) A description of the system's method of selling preemptible time based upon advertiser demand, commonly known as the “current selling level,” with the stipulation that candidates will be able to purchase at these demand-generated rates in the same manner as commercial advertisers;
(d) An approximation of the likelihood of preemption for each kind of preemptible time; and
(e) An explanation of the system's sales practices, if any, that are based on audience delivery, with the stipulation that candidates will be able to purchase this kind of time, if available to commercial advertisers.
