Notes to the consolidated financial statements
1 Summary of significant accounting policies
The accompanying consolidated financial statements of Credit Suisse Group (the Group) are prepared in accordance with accounting principles generally accepted in the United States of America (US GAAP) and are stated in Swiss francs (CHF). The financial year for the Group ends on December 31. Certain reclassifications have been made to the prior year’s financial statements to conform to the current year’s presentation and had no impact on net income or shareholders’ equity.
In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated balance sheets and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
