In this case, if the date specified in Article 1, item (vi) (Effective Date) of the Supplementary Provisions falls after the Effective Date of the Trust Act, with regard to the application of Article 291, paragraph (1), item (iv) of the New Order during the period from the Effective Date of the Trust Act until the day before the date specified in Article 1, item (vi) of the Supplementary Provisions, the phrase "Article 2, paragraph (14)" in that item is deemed to be replaced with "Article 2, paragraph (21)".
