Article 99b
However, where the publication of the identity of the legal persons or of the personal data of the natural persons is considered by the competent authority to be disproportionate following a case-by-case assessment conducted on the proportionality of the publication of such data, or where publication jeopardises the stability of financial markets or an ongoing investigation, Member States shall ensure that competent authorities do one of the following:
defer the publication of the decision to impose the sanction or measure until the reasons for non-publication cease to exist;
publish the decision to impose the sanction or measure on an anonymous basis in a manner which complies with national law, if such anonymous publication ensures effective protection of the personal data concerned; or
not publish the decision to impose a sanction or measure in the event that the options laid down in points (a) and (b) are considered to be insufficient to ensure:
that the stability of the financial markets would not be put in jeopardy;
the proportionality of the publication of such decisions with regard to measures which are deemed to be of a minor nature.
In the case of a decision to publish a sanction or measure on an anonymous basis, the publication of the relevant data may be postponed for a reasonable period of time if it is envisaged that within that period the reasons for anonymous publication shall cease to exist.
