Introduction

Treasury, which is part of the Corporate Center, is responsible for the management of UBS’s financial resources.

Our treasury department assumes market risk as a result of its balance sheet and capital management responsibilities. Treasury manages the interest rate risk arising from the funding of non-business items and the transfer of long-term interest rate risk from other Business Groups. It is also responsible for the foreign exchange risk resulting from the multi-currency nature of our business.

Treasury manages UBS's consolidated equity in order to protect our capital ratios and to generate a stable interest income stream.

1 For 2005, Treasury VaR differs from Corporate Center VaR, which also included Private Banks up to their sale on 5 December 2005. For 2006, Treasury is the only contributor to Corporate Center VaR. 2 As the minimum and maximum occur on different days for different risk types, it is not meaningful to calculate a portfolio diversification effect.
