(1) "Sponsored political committees," "sponsors of political committees," and "authorized committees," as those terms are used in the act and these rules, are defined in RCW 42.17A.005. This rule applies to political committees that are not authorized by a candidate, or by the public official against whom recall charges have been filed.

(2) A sponsored political committee must include on its C-1pc the name of at least one sponsor in the committee's name.

(3) For purposes of determining whether a political committee is sponsored, as defined in RCW 42.17A.005, by having received eighty percent or more of its contributions from a person or from the person's members, officers, employees, or shareholders, the political committee organized to support or oppose a particular candidate or ballot proposition must consider all contributions received by the committee in the previous twelve months.

(4) A sponsored political committee must amend its C-1pc sixty days before an election in which it participates if the committee's name on its most recently filed C-1pc does not include at least one current sponsor. To determine if the committee received eighty percent or more of its contributions from a person or from the person's members, officers, employees, or shareholders at the time of the amendment:

(a) A political committee not organized to support or oppose a particular candidate or ballot proposition must consider all contributions received in the previous twelve months through the date of filing the amended C-1pc.

(b) A committee organized to support or oppose a particular candidate or ballot proposition must consider all contributions received from the time the committee was organized or filed its initial C-1pc, whichever is earlier.
