If, at any time after the issue of the listing document (including any base listing document, stand alone listing document or supplemental listing document) and before the commencement of dealings in the structured products for which listing is sought, the issuer becomes aware that:-

(1) there has been a significant change affecting any matter contained in the listing document; or
(2) a significant new matter has arisen, the inclusion of information in respect of which would have been required to be included in such listing document if it had arisen before such listing document was issued,

the issuer (unless the Exchange agrees otherwise) shall, as soon as practicable, submit to the Exchange for its review a supplementary listing document giving details of the change or new matters. For this purpose "significant" means significant for the purpose of making an informed assessment of the matters mentioned in rule 15A.66.
