Financial Markets Act, 2012 (Act No. 19 of 2012)RegulationsFinancial Markets Act RegulationsChapter VI : Central Counterparties40.7 Review of models using test results |
| (1) | A central counterparty must— |
| (a) | have clear procedures to determine the amount of additional margin it may need to collect, including on an intraday basis, and to recalibrate its margin model where back testing indicates that the model did not perform as expected with the result that it does not identify the appropriate amount of initial margin necessary to achieve the intended level of confidence; |
| (b) | where it has determined that it is necessary to call additional margin, do so by the next margin call; |
| (c) | evaluate the source of testing exceptions highlighted by its back tests; |
| (d) | depending on the source of exceptions, determine whether a fundamental change to the margin model, or to the models that input into it, is required and whether the recalibration of current parameters is necessary; |
| (e) | evaluate the sources of testing exceptions highlighted by its stress tests; |
| (f) | determine whether a fundamental change to its models, their methodologies or its liquidity risk management framework is required or if the recalibration of current parameters or assumptions is necessary, on the basis of the sources of exceptions; |
| (g) | where the results of the tests show an insufficient coverage of margin, default fund or other financial resources, increase overall coverage of its financial resources to an acceptable level by the next margin call; |
| (h) | where the results of the tests show insufficient liquid financial resources, increase its liquid financial resources to an acceptable level as soon as is practicable; and |
| (i) | in reviewing its models, their methodologies and the liquidity risk management framework, monitor the frequency of reoccurring testing exceptions to identify and resolve issues appropriately and without undue delay. |
