In accordance with IAS 12, deferred taxes are recognised for all differences between the tax accounts and the IFRS balance sheet, using the currently enacted tax rate. Currently, deferred taxes are primarily formed on the differences between the IFRS carrying amounts of the properties and their carrying amounts for tax purposes. A uniform corporation tax rate of 15% plus the solidarity surcharge of 5.5% was used for German companies, and a rate of 16.45% for trade tax. The respective local tax rates were applied for foreign companies. In accordance with IAS 12.74, deferred tax assets on existing loss carryforwards are offset against deferred tax liabilities.
