Gov. Code, § 84503

(a) Any advertisement not described in subdivision (b) of Section 84504.3 that is paid for by a committee pursuant to subdivision (a) of Section 82013, other than a political party committee or a candidate controlled committee established for an elective office of the controlling candidate, shall include the words “Ad Committee’s Top Funders” unless only one contributor qualifies as a top contributor, in which case the advertisement shall include the words “Ad Committee’s Top Funder.” These words shall be followed by the names of the top contributors to the committee paying for the advertisement. If fewer than three contributors qualify as top contributors, only those contributors that qualify shall be disclosed pursuant to this section. If there are no contributors that qualify as top contributors, this disclosure is not required.

(b) The disclosure of a top contributor pursuant to this section shall not include terms such as “incorporated,” “committee,” “political action committee,” or “corporation,” or abbreviations of these terms, unless the term is part of the contributor’s name in common usage or parlance.

(c) If this article requires the disclosure of the name of a top contributor that is a committee pursuant to subdivision (a) of Section 82013 and is a sponsored committee pursuant to Section 82048.7 with a single sponsor, only the name of the single sponsoring organization shall be disclosed.

(d) This section does not apply to a committee as defined by subdivision (b) or (c) of Section 82013.

(e) Notwithstanding subdivision (a), if an advertisement is a printed letter, internet website, email message, or text message, the text described in subdivision (a) may include the words “Committee Top Funders” or “Committee Top Funder” instead of “Ad Committee’s Top Funders” or “Ad Committee’s Top Funder.”
