(3)To limit unnecessary costs for issuers, an exemption document should be lighter where, in connection with a transaction, the equity securities offered to the public or to be admitted to trading on a regulated market are fungible with equity securities already admitted to trading on a regulated market, and represent a small percentage of those equity securities. The reduced content of the exemption document in such a situation should be specified. However, in such a situation an issuer should not be prevented from benefiting from the exemptions laid down in Article 1(5), first subparagraph, points (a) or (b), of Regulation (EU) 2017/1129.
