2)Non-impaired receivables overdue for more than 90 days

3)These concern COVID-19 loans.

The definitions of ‘overdue’ and ‘impaired’ as well as the methodology for identifying impaired loans are described in Section 3 ‘Risk management’ of the consolidated notes to the 2025 Annual Report and correspond to the regulatory terms. For loans that (a) are more than 90 days past due, (b) involve a debtor in liquidation or (c) are subject to agreed interest concessions below refinancing costs, collective (lump-sum) value adjustments are recognised for loan amounts up to 100,000 Swiss francs. Value adjustments are made for inherent default risks for larger loans where their collateral is fully recoverable or for non-impaired loans and contingent liabilities. LUKB does not apply a generally applicable definition of restructured loans. Characteristics of restructuring aimed at avoiding payment defaults include special interest rates (whereby loans bearing interest below the refinancing costs are considered non-performing loans), the deferral of interest and amortisation payments (exposures with interest and/or amortisation outstanding > 90 days are also considered non-performing loans) or the subordination of our loan.

CRC: Qualitative disclosure requirements related to credit risk mitigation techniques

The offsetting of loans and liabilities both on and off the balance sheet is explained in Section 2 ‘General valuation principles’ of the consolidated notes to the 2025 Annual Report. In addition, the positive and negative replacement values before taking into account the netting agreements are presented in Section 8.4 ‘Derivative financial instruments (assets and liabilities)’ of the consolidated notes to the 2025 Annual Report and Section 6.4 ‘Derivative financial instruments (assets and liabilities)’ of the parent company notes to the 2025 Annual Report.

If guarantees or sureties are accepted to mitigate credit risks, the guarantors and surety providers must be assessed in the same way as the borrowers and, where appropriate, are subject to the rating process.

Concentration risks are limited by maximum limits per credit exposure, depending on the collateral or the type of borrower. As at 31 December 2025, the highest proportion of collateral used by an issuer was 6 % of Tier 1 capital.

CRD: Qualitative disclosures on banks' use of external credit ratings under the standardised approach for credit risk

External ratings from fedafin (restricted according to the FINMA list of ‘recognised rating agencies’), Moody's and Standard & Poor's are used to determine capital requirements. The ratings of Swiss Export Risk Insurance (SERV) are no longer used for the counterparty group ‘Central governments and central banks’.
