Evidence gaps

• Exact dates and matters at Symphony Infrastructure Partners, Piper Alderman and Cowell Clarke are incomplete; client-confidential work cannot be assessed from public sources.

• The issuer-reported AICD credential and director experience have not been verified against professional-body or appointment records; no current outside directorship was found in the sources reviewed.

• Public-web legal searches do not substitute for comprehensive court, disciplinary or regulator checks; no adverse conclusion is implied.
