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 2006, 31 December 2005 and 31 December 2004 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 88% for 2006 (86% for 2005 and 86% for 2004). The percentage of total average interest-bearing liabilities attributable to foreign activities was 85% for 2006 (84% for 2005 and 83% for 2004). 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.

Analysis of Changes in Interest Income and Expense

The following tables allocate, by categories of interest-earning assets and interest-bearing liabilities, the changes in interest income and expense due to changes in volume and interest rates for the year ended 31 December 2006 compared with the year ended 31 December 2005, and for the year ended 31 December 2005 compared with the year ­ended 31 December 2004. Volume and rate variances have been calculated on movements in average balances and changes in interest rates. Changes due to a combination of volume and rates have been allocated proportionally. Refer to page 245 of Industry Guide 3 for a discussion of the treatment of impaired, non-performing and restructured loans.

Deposits

The following table analyzes average deposits and the average rates on each deposit category listed below for the years ended 31 December 2006, 2005 and 2004. 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 78,234 million, CHF 54,968 million and CHF 49,699 million at 31 December 2006, 31 December 2005 and 31 December 2004, respectively.

Due from Banks and Loans (gross)

The Group's lending portfolio is widely diversified across ­industry sectors with no significant concentrations of credit risk. CHF 152.9 billion (42% of the total) consists of loans to thousands of private households, predominantly in ­Switzerland, and mostly secured by mortgages, financial collateral or other assets. Exposure to Banks and Financial institutions amounted to CHF 138 billion (38% of the ­total). This i­ncludes cash posted as collateral by UBS against negative replacement values on derivatives or other positions, which, from a risk perspective, is not considered lending but is a key component of the measurement of counterparty risk taken in connection with the underlying products. ­Exposure to banks includes money market deposits with highly rated ­institutions. Excluding financial institutions, the largest ­industry sector exposure is CHF 25 billion (7% of the total) to the Services sector. For further discussion of the lending portfolio, see the Risk Management chapter of the Handbook 2006/2007. The following ­table illustrates diversification of the lending portfolio among industry sectors at 31 December 2006, 2005, 2004, 2003 and 2002. The industry categories presented are consistent with the classification of loans for reporting to the Swiss Federal ­Banking Commission and Swiss National Bank. The table ­below does not include loans designated at fair value.

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 2006, 2005, 2004, 2003 or 2002.

In addition to the non-performing loans shown above, the Group had CHF 710 million, CHF 1,071 million, CHF 1,144 million, CHF 2,241 million and CHF 3,875 million in "other impaired loans" for the years ended 31 December 2006, 2005, 2004, 2003 and 2002, respectively.

Other impaired loans are loans where the Group's credit officers have expressed doubts as to the ability of the borrowers to repay the loans. For the years ended 31 December 2006, 2005 and 2004, they are loans not considered "non-performing" in accordance with Swiss regulatory guidelines, and for the years ended 31 December 2003 and 2002, they are loans that were current or less than 90 days in arrears with respect to payment of principal or interest. As of 31 December 2006, 31 December 2005 and 31 December 2004, specific allowances of CHF 106 million, CHF 200 million, CHF 241 million, respectively, had been established against these loans.

Cross-border Outstandings

Cross-border outstandings consist of general banking products such as loans and deposits with third parties, credit equivalents of over-the-counter (OTC) derivatives and securities financing, and the market value of the inventory of debt securities. Outstandings are monitored and reported on an ongoing basis by the credit risk 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. Prior periods have been adjusted to conform to the current year's presentation.

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 2006, 2005 and 2004. At 31 December 2006, 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 2006 / 2007.

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 due to 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.
