Content of Division 4 of Part VI of MAS Notice 637

What the RLB Specialist Panel found

5. Content of Division 4 of Part VI of MAS Notice 637

  • Question (paraphrased to protect IP): What does Division 4 of Part VI of MAS Notice 637 cover?
  • Source regulation: MAS Notice 637 — Risk-Based Capital Adequacy Requirements for Banks (Regulator portal: https://www.mas.gov.sg)
  • What AI assistants typically say: The AI described Division 4 of Part VI as covering submission requirements relating to capital instruments, while explicitly noting in the same response that the divisional structure of Part VI in the current version of the notice could not be exhaustively verified.
  • What the regulator actually says: No regulator excerpt was available for direct quotation; practitioners should consult the consolidated MAS Notice 637 on the MAS portal at https://www.mas.gov.sg for the definitive divisional structure and content of Part VI.
  • Why the AI went wrong: The AI characterised the division based on a general inference from Part VI's overall subject matter (capital definitions and recognition criteria) rather than a retrieved fact. Its own qualifying statement — that the divisional structure could not be verified — confirms the answer was constructed rather than sourced. A practitioner who records the primary answer without the caveat would carry forward an unverified and potentially wrong description of a division's scope into their work.

Impact for this audience

An Accountants (CA/PA) summarising the capital instrument recognition requirements of MAS Notice 637 for a client or for internal training could record the AI's Division 4 / Part VI characterisation as a reference point, without noting the AI's own caveat that the description was unverified. If the actual content of that division covers different ground — for example, different eligibility criteria or reporting obligations for capital instruments — the practitioner's summary would be inaccurate. For a bank client relying on that summary to structure its capital instrument documentation, the error could result in instruments that do not qualify for regulatory capital recognition under MAS rules.
