D – Information Required by Industry Guide 3

Selected Statistical Information

The tables below set forth selected statistical information regarding the Group’s banking operations extracted from the Financial Statements. Unless otherwise indicated, average balances for the years ended 31 December 2005, 31 December 2004 and 31 December 2003 are calculated from monthly data. The distinction between domestic and foreign is generally based on the booking location. For loans, this method is not significantly different from an analysis based on the domicile of the borrower.

Special Content

1 Due to customers in foreign offices consists mainly of time deposits.

The percentage of total average interest-earning assets attributable to foreign activities was 86% for 2005 (86% for 2004 and 85% for 2003). The percentage of total average interest-bearing liabilities attributable to foreign activities was 84% for 2005 (83% for 2004 and 82% for 2003). All assets and liabilities are translated into CHF at uniform month-end rates. Interest income and expense are translated at monthly average rates.

Average rates earned and paid on assets and liabilities can change from period to period based on the changes in interest rates in general, but are also affected by changes in the currency mix included in the assets and liabilities. This is especially true for foreign assets and liabilities. Tax-exempt income is not recorded on a tax-equivalent basis. For all three years presented, tax-exempt income is considered to be insignificant and the impact from such income is therefore negligible.
