Each executive lobbyist shall file an Executive Lobbyist Report before the sixteenth day of January, April, July and October for the preceding calendar quarter. Except for good cause shown, any executive lobbyist who, during a calendar year, files more than one Executive Lobbyist Report after the date it is due shall be deemed to have intentionally failed to file the report in violation of these Rules. An executive lobbyist who also is registered as a legislative lobbyist may choose to file reports as an executive lobbyist on the same dates that he or she files reports as a legislative lobbyist.
