This note describes the company’s impairment model for financial
assets that are debt instruments and that are not classified at fair
value through profit or loss.
Sparebanken Vest Boligkreditt AS has prepared a procedure for
the quarterly calculation of losses based on data warehouses that
contain historical information about account and customer data
for the whole credit portfolio, loans, credit and guarantees.
The goal of the model is to calculate expected credit loss (ECL)
based on forward-looking and unbiased estimates.
The loss estimates will be calculated on the basis of 12-month and
lifetime probability of default (PD), loss given default (LGD) and
exposure at default (EAD). Historical data about the observed
default rate (PD) and the observed loss given default (LGD) form
the basis for producing good estimates of future PD and LGD
values. Sparebanken Vest Boligkreditt AS uses self-developed
macro model to be able to provide forward-looking estimates for
PD, while the LGD models have built-in macro parameters.
Forward-looking EAD is based on agreed repayment plans and
observed levels of actual repayments and redemptions. All
estimates shall be as unbiased as possible. They thereby differ
from corresponding estimates for PD, LGD and EAD that are used
in the calculation of capital. The estimates used to calculate
capital are more conservative, for example by including safety
margins/MoC at the same time as LGD and EAD are estimated for
serious economic downturns.
In line with IFRS 9, the company groups its loans into three stages
based on the probability of default (PD) at the time of recognition
compared with the balance sheet date, and instalments paid more
than 30 days after the due date. In other words, each individual
loan (or commitment) is classified as Stage 1, 2 or 3. This means
that one and the same customer can have loans classified in
different stages.
Sparebanken Vest Boligkreditt AS uses the same PD model as in
IRB, but without calibration, meaning without safety margins
together with the macro model, as the basis for assessing
increased credit risk. Validation shows that it is accurate for PD
estimates from PD models both short and long timeframes.
Lifetime is set equal to the remaining term for those engagements
that have information about agreed redemption.
Stage 1: The starting point for all financial assets covered by the
general loss model. A loss provision corresponding to 12-month
expected losses, meaning losses relating to incidents that may
occur in the 12 months after the reporting date, will be made for all
assets for which the credit risk is not significantly higher than
upon initial recognition. This category includes all assets not
transferred to Stage 2 or 3.
Stage 2: Stage 2 includes assets for which the credit risk has
increased significantly since initial recognition, but where there is
no objective evidence of a loss. For these assets, a provision for
lifetime expected losses will be made. As regards delimitation in
relation to Stage 1, the company itself defines what constitutes a
significant increase in credit risk. However, IFRS 9 states that a
significant increase in credit risk will have occurred, unless this
can be refuted, if a significant overdraft has a duration 30 to 90
days (90 days or more is defined as a default).
PD
The company uses the PD level as the primary criteria for
significantly increased credit risk. Predicted PD at the time of
reporting is compared with predicted PD in the active model
version, rescored at the time the loan was furnished. If PD has
more than doubled since the loan was furnished and is at least
0.6%, it is classified as Stage 2.
Payment reliefs
Commitments with payment reliefs are also classified as Stage 2.
Commitments with payment facilities include commitments where
more favourable terms have been provided (renegotiation), or
refinancing of a commitment, as a result of the debtor having
financial problems. The criterion that the debtor is in financial
difficulties distinguishes payment facilitations from ordinary
commercial renegotiation of terms. In other words, it is an
additional factor that the company would not have granted a loan
on these terms in an ordinary loan issue. This defines
“forbearance”. If a commitment falls into this category, a
quarantine of 24 months is generated before it is declared healthy.
These engagements are overridden to Stage 2 - if they do not
already exist in Stage 2 or 3, and PD can be upregulated.
Stage 3: Stage 3 of the loss model includes assets for which the
credit risk has increased significantly since initial recognition, and
where there is objective evidence of a loss event on the balance
sheet date. For these assets, a provision for lifetime expected
losses will be made.
Indicators that are assessed when decisions are made regarding
whether there is objective evidence of loss are material financial
problems on the part of the debtor, default of payment or other
serious breaches of contract, approved deferments of payment or
new credit for the payment of an instalment, agreed changes in
the interest rate or other terms and conditions relating to the
agreement as a result of the debtor’s financial problems. If a loss
event is identified, consideration is given to whether the loss
events in question have reduced the estimated future cash flows
from the commitment.
The definition of default in Stage 3 also concurs with internal risk
management and capital requirement calculations. Also here, 90
days’ delayed payment is used as an important criterion for
default.
Migration from Stage 3 to Stage 2 and migration from Stage 2 to
Stage 1
Commitments will migrate from Stage 3 to Stage 2 when they are
no longer in default. Commitment in Stage 2 will migrate to Stage 1
at the time a commitment does not have a significant increase in
credit risk since the inclusion date according to the definitions
referred to above. The exception is commitment registered as
forbearance which has a quarantine period if it has first come into
this category.
Recognition and derecognition
The loss model is devised so that the establishment of a new loan
account is defined as a new commitment, while the redemption of
a loan account is defined as derecognition. Reference is otherwise
made to the section on recognition and derecognition in Note 1
– Accounting principles. The need to write down the loan (the loss
being booked against the customer’s loan) is confirmed once all
security has been realised and it is certain that no further
payments will be received on the loan. The claim on the customer
remains and will be followed up unless it has been agreed with the
customer that the loan is to be written off.
Forward-looking information
The basis for the macro bases case is taken from SSB’s (Statistics
Norway) macroeconomic figures. This ensures independence in the
forecasts and good quality of input. The three scenarios in the
model consist of a neutral case that covers a probability range of
60%, as well as a downside case and an upside case with a
