Concentration risk and own risk hedging

As per IFR article 36 paragraph 1 investment firm shall calculate exposure value with regard to a client or group of connected clients for the purposes of concentration risk as the exposure value of contracts and transactions referred to in Article 25(1) with the client in question, calculated in the manner laid down in Article 27. The question is whether the concentration risk should be also calculated for financial counterparties (e.g. members of QCCP) who investment firms hedge their own risk with (hedging of positions arising from derivatives with their clients).

It is clearly stated in IFR article 36 that concentration risk should be calculated for client or a group of connected client, but no mention about counterparties who the investment firms hedge their own risk with.
