CA-4.3.20
For banks using the standard haircuts, the framework below will apply to take into account the impact of master netting agreements.
E* = max {0, [(Σ(E) - Σ(C)) + Σ (ES × HS) +Σ (EFX × HFX)]}25
where:
E* = the exposure value after risk mitigation
E = current value of the exposure
C = the value of the collateral received
ES = absolute value of the net position in a given security
HS = haircut appropriate to ES
EFX = absolute value of the net position in a currency different from the settlement currency
HFX = haircut appropriate for currency mismatch
25The starting point for this formula is the formula in paragraph CA-4.3.3 which can also be presented as the following: E* = max {0, [(E - C) + (E x He) + (C x Hc) + (C x Hfx)]}
