Only those certificates or data, which were registered, recorded and forwarded in any other legally specified way can be considered as securities which have the necessary pre-defined elements and whose issuance is permitted by the legal regulations. The CMA mentions secondary securities, which are construed as custody certificates issued for securities falling within the scope of the act, while the definition of the elements and the conditions for the issuance of such securities are left within the scope of legal regulations at a lower level.

Dematerialised securities exist and can be forwarded in electronic form as opposed to printed (physical) securities. Disposal over dematerialised securities is possible in the form of crediting and debiting the account in question. In the case of printed securities, the same is carried out by depositing the issued security in the vault, on the securities custody account or by debiting the custody account.

The regulation obviously set the strengthening of dematerialised securities as its goal, since securities can only be issued publicly in electronic form. The rules for transformation also serve this goal. Accordingly, as of the day of the transformation, the issuer declares the converted series of securities as invalid and transforms them into an electronic form. In the case of the transformation of debt securities and investment coupons, the owner of the printed security can request the crediting of the dematerialised security to the securities account by submitting the security and specifying the investment service provider managing the securities account, by indicating the expiry of the security or the cessation of the investment fund that issued the investment coupon.
