| (b) | assign at least 25% weight to stressed observations in the look-back period calculated in accordance with Regulations 33.4; or |
| (c) | ensure that its margin requirements are not lower than those that would be calculated using volatility estimated over a 10 year historical look-back period. |
| (3) | When a central counterparty revises the parameters of the margin model in order to better reflect current market conditions, it must take into account any potential procyclical effects of such revision. |
