Before being admitted to trading, issuers are required to undergo an approval process as stipulated by public law. Together with at least one bank, a financial service institution, or a company that does business under the provisions of article 53, paragraph 1, no. 1, or article 53b, paragraph 1, no. 1 of the Banking Act, prospective participants must submit an application to the Admissions Board of the respective exchange. Companies already listed on the Regulated Market at one German exchange can apply for admission to another exchange without a supporting institution.
