The accompanying condensed consolidated interim financial statements, which include Deutsche Bank AG and its subsidiaries (collectively the “Group”), are stated in euros, the presentation currency of the Group. They are presented in accordance with the requirements of IAS 34, “Interim Financial Reporting”, and have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”) and endorsed by the European Union (“EU”). The Group’s application of IFRS results in no differences between IFRS as issued by the IASB and IFRS as endorsed by the EU.
Deutsche Bank’s condensed consolidated interim financial statements are unaudited and include supplementary disclosures on segment information, income statement, balance sheet and other financial information. They should be read in conjunction with the audited consolidated financial statements of Deutsche Bank for 2011, for which the same accounting policies have been applied.
The preparation of financial statements under IFRS requires management to make estimates and assumptions for certain categories of assets and liabilities. Areas where this is required include the fair value of certain financial assets and liabilities, the reclassification of financial assets, the impairment of loans and provision for off-balance-sheet positions, the impairment of other financial assets and non-financial assets, the recognition and measurement of deferred tax assets, and the accounting for legal and regulatory contingencies and uncertain tax positions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the balance sheet date, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from management’s estimates and the results reported should not be regarded as necessarily indicative of results that may be expected for the entire year.
Since the second quarter 2011, the Group’s valuation approach for substantially all of its collateralized derivative contracts has moved to using the overnight indexed swap (OIS) curve in order to more consistently manage the interest rate and funding risks associated with collateralized derivatives in line with their pricing. This change in approach to OIS did not have a material impact on the Group’s consolidated financial statements in the three months ended March 31, 2012.
