Disclaimer (2/2) Cautionary statements relating to certain preliminary financial information This presentation contains certain preliminary financial information for the historical periods according to the future intended divisional structure of the Group. This information has been derived from management accounts, is preliminary in nature, does not reflect the complete restated results and is subject to change. Our independent registered public accounting firm has not audited, reviewed or performed any procedures with respect to this preliminary information and, accordingly, does not express an opinion or any other form of assurance with respect to this data. There can be no assurance that the final results for these periods will not differ from these preliminary results, and any such differences could be material. Accordingly, you should not place undue reliance on this preliminary information. Statement regarding non-GAAP financial measures This presentation contains non-GAAP financial measures, including results excluding certain items included in our reported results as well as return on regulatory capital and return on tangible equity (which is based on tangible shareholders' equity). Further details and information needed to reconcile such non-GAAP financial measures to the most directly comparable measures under US GAAP can be found in the Appendix, which is available on our website at www.credit-suisse.com. Our estimates, ambitions, objectives, aspirations and targets often include metrics that are non-GAAP financial measures and are unaudited. A reconciliation of these measures to the nearest GAAP measures is unavailable without unreasonable efforts. Results excluding certain items included in our reported results do not include items such as goodwill impairment, major litigation provisions, real estate gains, impacts from foreign exchange and other revenue and expense items included in our reported results, all of which are unavailable on a prospective basis. Return on tangible equity is based on tangible shareholders' equity, a non-GAAP financial measure also known as tangible book value, which is calculated by deducting goodwill and other intangible assets from total shareholders' equity as presented in our balance sheet, both of which are unavailable on a prospective basis. Return on regulatory capital (a non-GAAP financial measure) is calculated using income/(loss) after tax and assumes a tax rate of 25% and capital allocated based on the average of 13.5% of risk-weighted assets and 4.25% of leverage exposure; the essential components of this calculation are unavailable on a prospective basis. Such estimates, ambitions, objectives and targets are calculated in a manner that is consistent with the accounting policies applied by us in preparing our financial statements. Statement regarding capital, liquidity and leverage Credit Suisse is subject to the Basel III framework, as implemented in Switzerland, as well as Swiss legislation and regulations for systemically important banks, which include capital, liquidity, leverage and large exposure requirements and rules for emergency plans designed to maintain systemically relevant functions in the event of threatened insolvency. Credit Suisse has adopted the Bank for International Settlements (BIS) leverage ratio framework, as issued by the Basel Committee on Banking Supervision (BCBS) and implemented in Switzerland by the Swiss Financial Market Supervisory Authority FINMA. Unless otherwise noted, leverage exposure is based on the BIS leverage ratio framework and consists of period-end balance sheet assets and prescribed regulatory adjustments. The tier 1 leverage ratio and CET1 leverage ratio are calculated as BIS tier 1 capital and CET1 capital, respectively, divided by period-end leverage exposure. Swiss leverage ratios are measured on the same period-end basis as the leverage exposure for the BIS leverage ratio. Unless otherwise noted, for periods in 2020, leverage exposure excludes cash held at central banks, after adjusting for the dividend paid in 2020.
