1. Financial counterparties and non-financial counterparties that enter into an OTC derivative contract not cleared by a CCP, shall ensure, exercising due diligence, that appropriate procedures and arrangements are in place to measure, monitor and mitigate operational risk and counterparty credit risk, including at least:
(b) formalised processes which are robust, resilient and auditable in order to reconcile portfolios, to manage the associated risk and to identify disputes between parties early and resolve them, and to monitor the value of outstanding contracts.
2. Financial counterparties and non-financial counterparties referred to in Article 10 shall mark-to-market on a daily basis the value of outstanding contracts. Where market conditions prevent marking-to-market, reliable and prudent marking-to model shall be used.
