Disclosure of events after reporting period [text block]	Note 34 Events after the reporting period Russia’s invasion of Ukraine Russia’s invasion of Ukraine on 24 February 2022 has triggered disruptions and uncertainties in the markets and the global economy, as well as coordinated implementation of sanctions by Switzerland, the United States, the European Union, the United Kingdom and others against Russia and, certain Russian entities and nationals. These events, together with potential counter- sanctions and other measures taken by Russia, impact UBS’s businesses. UBS’s country risk exposure to Russia was approximately USD 0.6 billion across its business divisions as of 31 December 2021. This exposure has been reduced since year-end 2021. In addition, UBS is currently monitoring settlement risk on certain open transactions with Russian bank- or non-bank counterparties or Russian underlyings, as market closures, the imposition of exchange controls, sanctions or other measures may limit our ability to settle existing transactions or to realize on collateral, which may result in unexpected increases in exposures. UBS’s balance sheet as of 31 December 2021 also included net assets of USD 51 million held in UBS’s Russian subsidiary, OOO UBS Bank. As of 3 March 2022, UBS also had approximately USD 0.2 billion of exposure arising from reliance on Russian assets as collateral on Lombard lending and other secured financing in Global Wealth Management. As of 3 March 2022, UBS identified a small number of Global Wealth Management clients subject to the recently introduced sanctions with total loans outstanding of under USD 10 million. UBS continues to closely monitor related effects on its financial statements, including estimated direct and indirect impacts on expected credit loss calculations and on fair value measurement of assets, liabilities and off-balance sheet exposures. The situation continues to evolve and broader implications for other counterparties of UBS, including financial institutions, are not possible to assess at this time; however, there were no material adverse effects on UBS’s financial statements as of 4 March 2022.
