Total allowances and provisions					(1,029)	(181)	(160)	(688)
1 The carrying amount of financial assets measured at amortized cost represents the total gross exposure net of the respective ECL allowances.

Coverage ratios are calculated for the core loan portfolio by taking ECL allowances and provisions divided by the gross carrying amount of the exposures. Core loan exposure is defined as the sum of Loans and advances to customers and Loans to financial advisors.

These ratios are influenced by the following key factors:

–lending in Switzerland includes government backed COVID-19 loans;

–Lombard loans are generally secured with marketable securities in portfolios that are, as a rule, highly diversified, with strict lending policies that are intended to ensure that credit risk is minimal under most circumstances;

–mortgage loans to private clients and real estate financing are controlled by conservative eligibility criteria, including low loan-to-value ratios and strong debt service capabilities; for example, more than 99% of the aggregated amount of Swiss residential mortgage loans would continue to be fully covered by real estate collateral even if the value of that collateral decreased by 20%, for a 30% reduction, more than 98% would be covered;

–the amount of unsecured retail lending (including credit cards) is insignificant;

–contractual maturities in the loan portfolio, which are a factor in the calculation of ECLs, are generally short, with a large part of the loan portfolio having contractual maturities of 12 months or less; and

–write-offs of ECL allowances against the gross loan balances when all or part of a financial asset is deemed uncollectible or forgiven, reduces the coverage ratios.

1 The carrying amount of financial assets measured at amortized cost represents the total gross exposure net of the respective ECL allowances.

These ratios are influenced by the following key factors:

–lending in Switzerland includes government backed COVID-19 loans;

residential mortgage loans would continue to be fully covered by real estate collateral even if the value of that collateral decreased by 20%, for a 30% reduction, more than 98% would be covered;

–the amount of unsecured retail lending (including credit cards) is insignificant;

–write-offs of ECL allowances against the gross loan balances when all or part of a financial asset is deemed uncollectible or forgiven, reduces the coverage ratios.
