Wash. Admin. Code § 284-18-330
In addition to the information expressly required to be included in Forms A, B, C, D, E, and F the commissioner may request further material information, if any, as may be necessary to make the information contained therein not misleading. The person filing may also file exhibits as it may desire in addition to those expressly required by the statement. The exhibits must be so marked as to indicate clearly the subject matters to which they refer. Changes to Forms A, B, C, D, E, or F must include on the top of the cover page the phrase: "Change No. (insert number) to" and must indicate the date of the change and not the date of the original filing.
