Julen, who is the Club's Chief Executive Officer, to whom the CFO post reports to?The appointment of a new CFO will not affect parity on the Club board as they will not be a director.
All Club directors (both Trust-appointed and non-Trust-appointed) have to be approved by the Trust board. The only way for parity to be broken is if the Trust board allow it to be broken.
As you have pointed out, there is currently a requirement for parity between the number of Trust-appointed and non-Trust-appointed directors on the Club board. This requirement cannot be changed or removed without the approval of the Trust membership.
