ANNEX Formulae to be used for the purpose of aggregating AVAs under Articles 9(6), 10(7) and 11(7)
Method 1
APVA=
(FV – PV) – 50 % · (FV – PV)
= (50 % · (FV – PV)
AVA= Σ APVA
Method 2
APVA=
max {0, (FV – PV) – 50 % · (EV – PV)}
= max {0, FV – 50 % · (EV + PV)}
AVA= Σ APVA
Where:
FV= The valuation exposure level fair value after any accounting adjustment applied in the institution's fair value that can be identified as addressing the same source of valuation uncertainty as the relevant AVA,
PV= The valuation exposure level prudent value determined in accordance with this Regulation,
EV= The expected value at a valuation exposure level taken from a range of possible values,
APVA= The valuation exposure level AVA after adjusting for aggregation,
AVA= The total category level AVA after adjusting for aggregation.
