(1) Earmarked contributions, as that term is used in RCW 42.17A.270 and 42.17A.460, means any contribution given to an intermediary or conduit, either a political committee, candidate or third party, with a designation, instruction, or encumbrance, whether direct or indirect, express or implied, oral or written, which is intended to result in or which does result in all or any part of the contribution being made to or for the promotion of a certain candidate, state official, or ballot proposition.

(2) For purposes of RCW 42.17A.405 and 42.17A.410, an earmarked contribution is deemed to be for the promotion of, and attributable to any limit applicable to the candidate, authorized committee, bona fide political party, caucus of the state legislature or political committee designated by the original contributor.

(3) If an earmarked contribution is given to an intermediary or conduit to be spent on behalf of a candidate and the entire amount given is not used for this purpose, the remainder of the contribution shall be given to the designated candidate unless its use is redesignated by the original contributor. If the conduit or intermediary exercises any direction or control over the use of the remainder of the contribution, then the amount of the remainder shall be considered a contribution from the original contributor and the conduit or intermediary to the recipient.

(4) The intermediary or conduit receiving the earmarked contribution shall notify the candidate or political committee for whose use or benefit the contribution is designated within two business days after receipt of the contribution.

(5) If an earmarked contribution is refused by the designated recipient candidate or political committee, the earmarked contribution must be returned by the intermediary or conduit to the original contributor within five business days of refusal.
