Risk-Weighted Assets (RWA)
Credit Risk is measured via the amount of risk-weighted assets (RWA), which is derived in the Standardized Approach for each deal by the product of its contractual residual debt and the corresponding risk weight. The risk weight itself depends on the type of the customer, and possibly also on the rating of the customer (in case of corporate customers) as well as on the currency (in case of claims on sovereigns) and the remaining time to maturity of the deal (in case of claims on banks). When calculating amounts of RWA, effects of credit risk mitigation (CRM) are taken into account by performing an optimization of the distribution of available collateral to corresponding claims in order to reduce the RWA amount.
Due to the facts that
- this deal belongs to a private customer
- the product type is a mortgage loan
- this deal is not a "past due loan"
- the loan-to-value ratio is more than 85%
the assigned risk weight for this deal is 100% at each posting date.
Since there is a collateral provided, the amount of RWA for this deals equals 100% of the difference between its contractual residual debt and the market value of the corresponding collateral.
Expected Credit Loss (ECL)
In the context of ECL calculation, the deal is processed in several components/steps.
- Segmentation
Segmentation is performed based on the following parameterization:
- Any loan with customer type "CORPCUST" (Corporate Customer) will be assigned to segment "IFRS9CI LOAN CORPORATE".
- Any loan with customer type "SMECUST" (SME Customer) will be assigned to segment "IFRS9CI LOAN SME".
- All remaining loans will be assigned to segment "IFRS9CI LOAN RETAIL".
Hence, this loan is assigned to segment “IFRS9CI LOAN RETAIL”. It means that all corresponding ECL models and configurations are applied to this deal.
- Stage Determination
For all segments except "IFRS9CI LOAN CORPORATE", "IFRS9CI GUARANTEE", "IFRS9CI MONEY MARKET" and "IFRS9CI BONDS", the stage will be assigned based on the number of days past due (DPD):
- Stage 1 for DPD <= 30 days
- Stage 2 for DPD > 30 days and DPD <= 90 days
- Stage 3 for DPD >90 days.
This deal has 0 DPD at all postings dates. Therefore, it is assigned to Stage 1 (HEALTHY) at each posting date.
- probability-weighted ECL calculation
Based on the determination of the stage, a 12-months ECL (stage 1) or a life-time ECL (stage 2 and 3) will be calculated for each deal.
- Since this deal is assigned to stage 1, a 12-months ECL is calculated.
- Based on the derived segment “IFRS9CI LOAN RETAIL”, external PD and LGD values (expert values) were applied.
- Theses external PD and LGD value were provided for two different economic scenarios:
- a "baseline" scenario (weighted by 75%)
- an "adverse" scenario (weighted by 25%)
- EAD was calculated as the sum of all future cashflows discounted with the effective interest rate.
- For each macroeconomic scenario, the corresponding ECL was calculated by the product of PD, LGD and EAD.
- Finally, the probability-weighted ECL is derived as the sum of 75% of the "baseline ECL" and 25% of the "adverse" ECL.
