Prudent Valuation - Guidelines and Sound Practices
The EU Capital Requirement Regulation (CRR) [8] and of EBA Regulatory Technical Standard for prudent valuation [15], published on Jan. 1st, 2014 and Jan. 28th, 2016, respectively, constitute the EU Prudent Valuation Framework. The CRR, art. 34, requires to Institutions a prudent valuation of positions measured at fair value and the deduction of the resulting Additional Valuation Adjustments (AVAs) from the Common Equity Tier One (CET1) capital. The art. 105 disciplines the AVAs intended to achieve an appropriate level of certainty in prudent value. The EBA RTS [15] allow two approaches to prudent valuation. The simplified approach, applicable by small financial institutions (with total absolute fair-valued assets and liabilities below EUR 15 billions), prescribes a very simple total AVA equal to 0.1% of the total fair value. The core approach, compulsory for institutions above the EUR 15 billion threshold, prescribes the calculation of 9 AVAs, referring to different sources of valuation uncertainty, as the excess of valuation adjustments required to achieve the prudent value with 90% level of confidence. Five out of nine AVAs include a 50% weight to take diversification into account and avoid double counting effects. Those positions for which a change in their fair value affects only partially the CET1 may be partially excluded from the AVAs calculation.
