The requirements of IFRS 9 relating to impairment are based on the model of expected credit loss.
The Group applies a three-step approach to the measurement of expected credit losses from financial instruments measured at amortised cost or at fair value through other comprehensive income, for which no impairment loss was recognised as at the moment of initial recognition. As a result of changes in the credit quality since the initial recognition, financial assets are transferred between the following three stages:
Stage 1: An allowance due to expected credit losses in 12-month horizon
If credit risk did not increase significantly from the date of the initial recognition, and the impairment of the loan was not identified from the moment of its granting, the Group recognises an allowance for the expected credit loss related to the probability of default within the next 12 months. Interest income on such assets is recognised based on the balance sheet amount (amortised cost before the adjustment for impairment allowance) using the effective interest rate.
Stage 2: An allowance due to expected credit losses for the entire lifetime – significant increase in the credit risk since the moment of initial recognition and no impairment of a financial asset identified.
In the case of an exposure for which credit risk has increased significantly since the moment of its initial recognition, but no impairment of the financial asset was identified, an impairment allowance is created for the expected credit loss for the entire financing period. Interest income on such assets is recognised based on the gross balance sheet amount (amortised cost before the adjustment for impairment allowance) using the effective interest rate.
Stage 3: An allowance due to expected credit losses for the entire lifetime – impairment of a financial asset
Financial assets are subject to impairment due to the credit risk resulting from an event or events that occurred after the initial recognition of a given asset. For financial assets, for which an impairment was identified, an allowance is created for the expected credit loss for the entire financing period, while interest income is recognised based on the net balance sheet value (including the impairment allowance) using the effective interest rate.
At each balance sheet date, the Group assesses whether there has been a significant increase in credit risk for financial assets since the moment of their initial recognition, by comparing the risk of loan default during the expected financing period as at the balance sheet date and the initial recognition date, using, among others, the internal credit risk assessment system, external credit ratings, information on delay in repayments and information from internal credit risk monitoring systems, such as warning letters and information about restructuring.
The Group assesses whether the credit risk has increased to a significant extent on the basis of individual and group assessment. In order to perform an impairment calculation on a group basis, financial assets are divided into homogeneous product groups based on common credit risk characteristics, taking into account the type of instrument, credit risk rating, initial recognition date, remaining maturity, industry branch, geographical location of the borrower and other relevant factors.
The value of expected credit loss is measured as the current value of all cash flow shortages in the expected life of a financial asset weighted with probability and discounted using the effective interest rate. The shortfall in cash flows is the difference between all contractual cash flows due to the Group and all cash flows that the Group expects to collect. The value of the expected credit loss is recognised in the statement of profit or loss in the impairment losses.
The Group takes into account historical data on credit losses and adjusts them to current observable data. In addition, the Group uses reasonable and justified forecasts of the future economic situation, including its own judgment based on experience, with the purpose of estimating the expected credit losses. IFRS 9 introduces an application of macroeconomic factors to the calculation of impairment losses on financial assets. These factors include: unemployment rate, interest rates, gross domestic product, inflation, commercial property prices, exchange rates, stock indices, and wage rates. IFRS 9 also requires an assessment of both the current and the forecasted direction of the economic cycles. The inclusion of forecast information in the calculation of impairment losses on financial assets increases the level of judgement to what extent these macroeconomic factors will affect the expected credit losses. The methodology and assumptions, including all forecasts of the future economic situation, are regularly monitored.
If in the subsequent period the allowance for expected credit losses decreases, and the decrease can be objectively related to an event occurring after the impairment was recognised, then the previously recognised impairment allowance is reversed by adjusting the allowance for expected credit losses. The amount of the reversed impairment allowance is recognised in the statement of profit or loss.
For debt instruments measured at fair value through other comprehensive income, the measurement of the expected credit loss is based on a three-step approach, as in the case of financial assets measured at amortised cost. The Group recognises the amount of the impairment loss in the statement of profit or loss, including the corresponding value recognised in other comprehensive income, without reducing the balance sheet amount of assets (i.e. their fair value) in the statement of financial position.
