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.

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.

Deposits

The following table analyzes average deposits and the average rates on each deposit category listed below for the years ended 31 December 2005, 2004 and 2003. The geographic allocation is based on the location of the office or branch where the deposit is made. Deposits by foreign depositors in domestic offices were CHF 54,968 million, CHF 49,699 million and CHF 49,857 million at 31 December 2005, 31 December 2004 and 31 December 2003, respectively.

At 31 December 2005, the maturity of time deposits exceeding CHF 150,000, or an equivalent amount in other currencies, was as follows:

Due from Banks and Loans (gross)

Loans are widely dispersed over industry sectors both within and outside Switzerland. With the exception of private households (foreign and domestic), banks and financial institutions outside Switzerland, and real estate and rentals in Switzerland, there is no material concentration of loans. For further discussion of the loan portfolio, see the Handbook 2005/2006. The following table illustrates the diversification of the loan portfolio among industry sectors at 31 December 2005, 2004, 2003, 2002 and 2001. The industry categories presented are consistent with the classification of loans for reporting to the Swiss Federal Banking Commission and Swiss National Bank.

At 31 December 2005, the total amounts of Due from banks and loans due after one year granted at fixed and floating rates are as follows:

Impaired and Non-performing Loans

A loan (included in Due from banks or Loans) is classified as non-performing: 1) when the payment of interest, principal or fees is overdue by more than 90 days and there is no firm evidence that they will be made good by later payments or the liquidation of collateral; 2) when insolvency proceedings have commenced; or 3) when obligations have been restructured on concessionary terms.

The gross interest income that would have been recorded on non-performing loans was CHF 81 million for domestic loans and CHF 8 million for foreign loans for the year ended 31 December 2005, CHF 107 million for domestic loans and CHF 17 million for foreign loans for the year ended 31 December 2004, CHF 171 million for domestic loans and CHF 23 million for foreign loans for the year ended 31 December 2003, CHF 148 million for domestic loans and CHF 53 million for foreign loans for the year ended 31 December 2002 and CHF 336 million for all non-performing loans for the year ended 31 December 2001.

The amount of interest income that was included in net income for those loans was CHF 72 million for domestic loans and CHF 9 million for foreign loans for the year ended 31 December 2005, CHF 106 million for domestic loans and CHF 8 million for foreign loans for the year ended 31 December 2004, CHF 163 million for domestic loans and CHF 8 million for foreign loans for the year ended 31 December 2003, CHF 152 million for domestic loans and CHF 22 million for foreign loans for the year ended 31 December 2002 and CHF 201 million for all non-performing loans for the year ended 31 December 2001. The table below provides an analysis of the Group’s non-performing loans. For further information see the Handbook 2005/2006.

UBS does not, as a matter of policy, typically restructure loans to accrue interest at rates different from the original contractual terms or reduce the principal amount of loans. Instead, specific loan allowances are established as necessary. Unrecognized interest related to restructured loans was not material to the results of operations in 2005, 2004, 2003, 2002 or 2001. In addition to the non-performing loans shown above, the Group had CHF 1,071 million, CHF 1,144 million, CHF 2,241 million, CHF 3,875 million and CHF 5,990 million in “other impaired loans” for the years ended 31 December 2005, 2004, 2003, 2002 and 2001, respectively. For the years ended 31 December 2003, 2002 and 2001, these are loans that are current or less than 90 days in arrears with respect to payment of principal or interest; and for the years ended 31December2005 and 2004, these are loans not considered “non-performing” in accordance with Swiss regulatory guidelines, but where the Group’s credit officers have expressed doubts as to the ability of the borrowers to repay the loans. As at 31 December 2005 and 31 December 2004, specific allowances of CHF 200 million and CHF 241 million, respectively, had been established against these loans.

Cross-Border Outstandings

Cross-border outstandings consist of general banking products such as loans (including unutilized commitments) and deposits with third parties, credit equivalents of over-the-counter (OTC) derivatives and repurchase agreements, and the market value of the inventory of securities. Outstandings are monitored and reported on an ongoing basis by the credit risk management and control organization with a dedicated country risk information system. With the exception of the 32 most developed economies, these exposures are rigorously limited. The following analysis excludes Due from banks and Loans from Industrial Holdings.

Claims that are secured by third-party guarantees are recorded against the guarantor’s country of domicile. Outstandings that are secured by collateral are recorded against the country where the asset could be liquidated. This follows the “Guidelines for the Management of Country Risk”, which are applicable to all banks that are supervised by the Swiss Federal Banking Commission.

The following tables list those countries for which cross-border outstandings exceeded 0.75% of total assets at 31 December 2005, 2004 and 2003. At 31 December 2005, there were no outstandings that exceeded 0.75% of total assets in any country currently facing liquidity problems that the Group expects would materially affect the country’s ability to service its obligations.

For more information on cross-border exposure, see the Handbook 2005/2006.

Summary of Movements in Allowances and Provisions for Credit Losses

The following table provides an analysis of movements in allowances and provisions for credit losses. The following analysis includes Due from banks from Industrial Holdings. UBS writes off loans against allowances only on final settlement of bankruptcy proceedings, the sale of the underlying assets and / or in case of debt forgiveness. Under Swiss law, a creditor can continue to collect from a debtor who has emerged from bankruptcy, unless the debt has been forgiven through a formal agreement.

Allocation of the Allowances and Provisions for Credit Losses

The following table provides an analysis of the allocation of the allowances and provisions for credit loss by industry sector and geographic location at 31 December 2005, 2004, 2003, 2002 and 2001. For a description of procedures with respect to allowances and provisions for credit losses, see the Handbook 2005/2006. The following analysis includes Due from banks from Industrial Holdings.

Due from Banks and Loans by Industry Sector (gross)

The following table presents the percentage of loans in each industry sector and geographic location to total loans. This table can be read in conjunction with the preceding table showing the breakdown of the allowances and provisions for credit losses by industry sector to evaluate the credit risks in each of the categories.
