Annex Formulae to be used for the purpose of aggregating AVAs under Article 9(6), Article 10(7) and Article 11(7)F1
United Kingdom
Formula for Method 1
| APVA | = | (FV – PV) – α · (FV – PV) = (1 – α) · (FV – PV) |
| AVA | = | Σ APVA |
Formula for Method 2
| APVA | = | max {0, (FV – PV) – α · (EV – PV)} = max {0, FV – α · EV – (1 – α) · PV} |
| AVA | = | Σ APVA |
Where:
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,
The valuation exposure-level prudent value determined in accordance with this Regulation,
The expected value at a valuation exposure level taken from a range of possible values,
The aggregation factor,
The valuation exposure-level AVA after adjusting for aggregation,
The total category-level AVA after adjusting for aggregation.
Institutions shall set the aggregation factor ‘ α ’ at 66 % until 31 December 2020 , after which they shall set the aggregation factor at 50 %.’
