Allowance and Provision Calculation
- Cash Flow and Forward Exposure - when Undrawn Flag is Y or N the 12 Month and
Lifetime Allowance is computed as follows:
- 12 Month Allowance = IF (12 Month ECL > Carrying Amount, Carrying Amount, 12 Month ECL)
- Lifetime Allowance = IF (Lifetime ECL > Carrying Amount, Carrying Amount, Lifetime ECL)
- Cash Flow and Forward Exposure - when Undrawn Flag is Y the 12 Month and Lifetime
Provision is computed as follows:
- 12 Month Provision = IF (12 Month ECL > Carrying Amount, 12 Month ECL - Carrying Amount, 0)
- Lifetime Allowance = IF (Lifetime ECL > Carrying Amount, Lifetime ECL - Carrying Amount, 0)
- Cash Flow and Forward Exposure - when Undrawn Flag is N the 12 Month and Lifetime
Provision is computed as follows:
- 12 Month Provision = Undrawn * CCF * 12 Month Provision Rate
- Lifetime Provision = Undrawn * CCF * Lifetime Provision Rate
- Provision Matrix Approach - when Undrawn flag Y or N the 12 Month and Lifetime
Allowance and Provision are computed as follows:
- 12 Month Allowance = Carrying Amount * 12 Month Provision Rate
- Lifetime Allowance = Carrying Amount * Lifetime Provision Rate
- 12 Month Provision = Undrawn * CCF * 12 Month Provision Rate
- Lifetime Provision = Undrawn * CCF * Lifetime Provision Rate
- Specific Provision - when Undrawn flag Y or N the 12 Month and Lifetime Allowance
and Provision are computed as follows:
- 12 Month Allowance = Carrying Amount * LGD * 12 Month PD
- Lifetime Allowance = Carrying Amount * LGD * Lifetime PD
- 12 Month Provision = Undrawn * CCF * LGD * 12 Month PD
- Lifetime Provision = Undrawn * CCF * LGD * Lifetime PD
- Expected Credit Loss Calculation
For all accounts, the 12 Month and Expected Credit Loss is calculated as follows:
- 12 Month ECL = 12 Month Allowance + 12 Month Provision
- Lifetime ECL = Lifetime Allowance + Lifetime Provision
- Apportioning ECL, Allowance, and Provision values from Cohorts to Individual
accounts
The apportioning of all following the six parameters are performed:
- 12 Month values of ECL, Allowance, and Provision
- Lifetime values of ECL, Allowance, and Provision
- Computation of final Reporting Values
The Reporting ECL, Reporting Allowance, and Reporting Provision values are computed as follows:
IF STAGE = 1
- Reporting ECL = 12 Month ECL
- Reporting Allowance = 12 Month Allowance
- Reporting Provision = 12 Month Provision
IF STAGE = 2 or 3
- Reporting ECL = Lifetime ECL
- Reporting Allowance = Lifetime Allowance
- Reporting Provision = Lifetime Provision
