Estimating the expected credit losses for loans
and advances to customers
In accordance with the provisions of International
Financial Reporting Standard 9,
Financial
Instruments,
(“IFRS 9”) the Management is required
to determine expected credit loss (“ECL”) that may
occur over either a 12 month period or the
remaining life of a financial asset, depending on the
classification of individual assets into risk categories
("stages"), taking into account the impact of future
macroeconomic conditions on the level of credit risk
allowances.
The Group’s loan portfolio consists of exposures
assessed for expected credit losses:
●
on an individual basis for individually significant
credit exposures; and
●
with the use of statistical models which estimate
allowances for credit losses for each of the
homogenous portfolios identified by the Group.
Estimating the level of allowances for expected
credit losses requires the application of a significant
degree of judgment with regard to the identification
of impaired loans and significant increase in credit
risk, the assessment of the customer's credit
quality, the value of collateral and expected
recoveries.
The management monitors the accuracy of
performance of the models, by comparing the
estimated results of the models to actual credit
losses (‘back-testing procedures’) to ensure that the
level of allowances for the expected credit losses
for loans and advances to customers is adequate.
In the models of expected credit losses the Group
uses the large volumes of data, therefore the
completeness and reliability of data can significantly
impact accuracy of the allowances for credit losses.
COVID-19 global pandemic significantly impacted
management’s determination of the allowances for
expected credit losses and required the application
of additional level of judgment. In order to address
the uncertainties inherent in the current and future
macroeconomic environment and to reflect all
relevant risk factors not captured in the Group’s
modelled results, the management applied expert
judgment and recognized allowance for the impact
of the COVID-19 pandemic on the forecasted
deterioration in the quality of the loan portfolio.
We determined that the level of allowance for
expected credit losses is a key audit matter due to:
●
the significant judgment applied by
management when designing future
We have started our audit procedures with updating
our understanding of the Group’s policies and
procedures relating to the estimation of allowances
for expected credit losses, especially the changes
applied to address the uncertainties resulting from the
COVID-19 global pandemic.
We tested the effectiveness of controls applied by the
management related to the recognition and
measurement of credit losses including, among
others, controls over:
●
the completeness and accuracy of input data
used;
●
verification of the models of probability of default
(PD), loss given default (LGD) and other
parameters;
●
the design of future macroeconomic scenarios,
forecasted macroeconomic variables, and the
probability-weighting of these scenarios;
●
the application of expert judgements.
In the area of statistical models, we performed the
following procedures, for which we involved our
internal specialists in the area of credit risk modelling:
●
the assessment whether the Group’s
methodology related to the estimation of
expected credit losses is in line with the
requirements of IFRS 9, in particular verification
of the Group’s approach to applying the criteria to
identify significant increase in credit risk, default
definition, PD and LGD parameters and including
forward-looking information when calculating
expected credit losses;
●
evaluating the appropriateness of the Group’s
assumptions and expert credit judgment used in
the model;
●
critical analysis of key judgments and
assumptions, including macroeconomic scenarios
and the probability-weightings assigned to
particular scenarios;
●
analysis of the model’s stability and adaptation to
current conditions;
●
independent tests of the credit risk parameters.
In the area of the individually assessed exposures,
we performed the following procedures:
●
we selected a sample taking into account various
risk criteria based on our professional judgment,
