For the calculation of initial margins the CCP shall at least respect the following confidence intervals: a for OTC derivatives, 99,5 %; b for financial instruments other than OTC derivatives, 99 %. 2 For the determination of the adequate confidence interval for each class of financial instruments it clears, a CCP shall in addition consider at least the following factors: a the complexities and level of pricing uncertainties of the class of financial instruments which may limit the validation of the calculation of initial and variation margin; b the risk characteristics of the class of financial instruments, which can include, but are not limited to, volatility, duration, liquidity, non-linear price characteristics, jump to default risk and wrong way risk; c the degree to which other risk controls do not adequately limit credit exposures; d the inherent leverage of the class of financial instruments, including whether the class of financial instrument is significantly volatile, is highly concentrated among a few market players or may be difficult to close out. 3 The CCP shall inform its competent authority and its clearing members on the criteria considered to determine the percentage applied to the calculation of the margins for each class of financial instruments. 4 Where a CCP clears OTC derivatives that have the same risk characteristics as derivatives executed on regulated markets or an equivalent third country market, on the basis of an assessment of the risk factors set out in paragraph 2, the CCP may use an alternative confidence interval of at least 99 % for those contracts if the risks of OTC derivatives contracts it clears are appropriately mitigated using such confidence interval and the conditions in paragraph 2 are respected.
