Notes to the financial statements
The Group s future obligations with respect to each generation (in the case of PEL products, a generation comprises all products with the same interest rate at inception; in the case of CEL products, all such products constitute a single generation) are measured by discounting potential future earnings from at-risk outstandings for that generation.
At-risk outstandings are estimated on the basis of a historical analysis of customer behaviour, and are equivalent to:
■ for the loan phase: statistically probable loans outstanding and actual loans outstanding;
■ for the savings phase: the difference between statistically probable outstandings and minimum expected outstandings, with minimum expected outstandings being deemed equivalent to unconditional term deposits.
Earnings for future periods from the savings phase are estimated as the difference between the reinvestment rate and the fixed savings interest rate on at-risk savings outstanding for the period in question. Earnings for future periods from the loan phase are estimated as the difference between the refinancing rate and the fixed loan interest rate on at-risk loans outstanding for the period in question.
The reinvestment rate for savings and the refinancing rate for loans are derived from the swap yield curve and from the spreads expected on financial instruments of similar type and maturity. Spreads are determined on the basis of actual spreads on fixed rate home loans in the case of the loan phase and products offered to individual clients in the case of the savings phase. In order to reflect the uncertainty of future interest rate trends, and the impact of such trends on customer behaviour models and on at-risk outstandings, the obligations are estimated using the Monte-Carlo method.
Where the sum of the Group s estimated future obligations with respect to the savings and loan phases of any generation of contracts indicates a potentially unfavourable situation for the Group, a provision is recognised (with no offset between generations) in the balance sheet in Provisions for contingencies and charges . Movements in this provision are recognised as interest income in the profit and loss account.
1.e.5 Impairment of financial assets measured at amortised cost and debt instruments measured at fair value through shareholders equity
The impairment model for credit risk is based on expected losses.
This model applies to loans and debt instruments measured at amortised cost or fair value through equity, to loan commitments and financial guarantee contracts that are not recognised at fair value, as well as to lease receivables, trade receivables and contract assets.
General model The Group identifies three stages that correspond each to a specific status with regards to the evolution of counterparty credit risk since the initial recognition of the asset.
■ 12-month expected credit losses ( stage 1 ): If at the reporting date, the credit risk of the financial instrument has not increased significantly since its initial recognition, this instrument is impaired at
an amount equal to 12-month expected credit losses (resulting from the risk of default within the next 12 months);
■ lifetime expected credit losses for non-impaired assets ( stage 2 ): The loss allowance is measured at an amount equal to the lifetime expected credit losses if the credit risk of the financial instrument has increased significantly since initial recognition, but the financial asset is not considered credit-impaired or doubtful;
■ lifetime expected credit losses for credit-impaired or doubtful financial assets ( stage 3 ): the loss allowance is also measured for an amount equal to the lifetime expected credit losses.
This general model is applied to all instruments within the scope of IFRS 9 impairment, except for purchased or originated credit-impaired financial assets and instruments for which a simplified model is used (see below).
The IFRS 9 expected credit loss approach is symmetrical, i.e. if lifetime expected credit losses have been recognised in a previous reporting period, and if it is assessed in the current reporting period that there is no longer any significant increase in credit risk since initial recognition, the loss allowance reverts to a 12-months expected credit loss.
As regards interest income, under stage 1 and 2, it is calculated on the gross carrying amount. Under stage 3 , interest income is calculated on the amortised cost (i.e. the gross carrying amount adjusted for the loss allowance).
Definition of default The definition of default is aligned with the Basel regulatory default definition, with a rebuttable presumption that the default occurs no later than 90 days past-due.
The definition of default is used consistently for assessing the increase in credit risk and measuring expected credit losses.
Credit-impaired or doubtful financial assets
Definition
A financial asset is considered credit-impaired or doubtful and classified in stage 3 when one or more events that have a detrimental impact on the estimated future cash flows of that financial asset have occurred.
At an individual level, objective evidence that a financial asset is credit- impaired includes observable data regarding the following events: the existence of accounts that are more than 90 days past due; knowledge or indications that the borrower meets significant financial difficulties, such that a risk can be considered to have arisen regardless of whether the borrower has missed any payments; concessions with respect to the credit terms granted to the borrower that the lender would not have considered had the borrower not been meeting financial difficulty (see section Restructuring of financial assets for financial difficulties ).
Specific cases of purchased or originated credit-impaired assets
In some cases, financial assets are credit-impaired at their initial recognition.
For these assets, there is no loss allowance accounted for at initial recognition. The effective interest rate is calculated taking into account the lifetime expected credit losses in the initial estimated cash flows. Any
