(7)Pursuant to the primary rules, CTCOs must adopt internal business rules — the internal rules and procedures of the CTCO — which conform to the applicable laws and regulations and allow the derivatives transactions to be performed properly and securely. Internal business rules also ensure that the financial standing of CTCOs is sufficient for undertaking the clearing of commodities; that the expected income and expenditure pertaining to the business of CTCOs are favorable; that the CTCOs' staff has sufficient knowledge and experience for conducting the clearing of commodities appropriately and with certainty; and that the structure and system of CTCOs are adequately developed so that settlement can function adequately. Those internal rules and procedures need to be approved by the competent minister and cannot be amended if the competent minister objects to them.
