The regulatory capital adequacy guidelines applicable to the Group are set forth by the Basel Committee on Banking Supervision, the secretariat of which is provided by the Bank for International Settlements (“BIS”) and by European Council directives, as implemented into German law. The German Federal Financial Supervisory Authority (Bundesanstalt für Finanzdienstleistungsaufsicht), in cooperation with the Deutsche Bundesbank supervises our compliance with such guidelines. Effective December 31, 2001, the German Federal Financial Supervisory Authority permitted the Group to calculate its BIS capital adequacy ratios on the basis of financial statements prepared in accordance with U.S. GAAP .
The BIS capital ratio is the principal measure of capital adequacy for international banks. This ratio compares a bank's regulatory capital with its counterparty risks and market price risks (which the Group refers to collectively as the “risk position”). Counterparty risk is measured for asset and off-balance sheet exposures according to broad categories of relative credit risk . The Group's market risk component is a multiple of its value-at-risk figure, which is calculated for regulatory purposes based on the Group's internal models. These models were approved by the German Federal Financial Supervisory Authority for use in determining the Group's market risk equivalent component of its risk position. A bank's regulatory capital is divided into three tiers (core or Tier I capital, supplementary or Tier II capital, and Tier III capital). Core or Tier I capital consists primarily of share capital, additional paid-in capital, retained earnings and hybrid capital components, such as noncumulative trust preferred securities and equity contributed on silent partnership interests (stille Beteiligungen), less intangible assets (principally goodwill) and the impact from the tax law changes (as described below). Supplementary or Tier II capital consists primarily of profit participation rights (Genussrechte), cumulative trust preferred securities, long-term subordinated debt, unrealized gains on listed securities and other inherent loss allowance. Tier III capital consists mainly of certain short-term subordinated liabilities and it may only cover market price risk. Banks may also use Tier I and Tier II capital that is in excess of the minimum required to cover counterparty risk (excess Tier I and Tier II capital) in order to cover market price risk. The minimum BIS total capital ratio (Tier I + Tier II + Tier III) is 8% of the risk position. The minimum BIS core capital ratio (Tier I) is 4% of the risk-weighted positions and 2.29% of the market risk equivalent. The minimum core capital ratio for the total risk position therefore depends on the weighted-average of risk-weighted positions and market risk equivalent. Under BIS guidelines, the amount of subordinated debt that may be included as Tier II capital is limited to 50% of Tier I capital. Total Tier II capital is limited to 100% of Tier I capital. Tier III capital is limited to 250% of the Tier I capital not required to cover counterparty risk.
The effect of the 1999/2000 German Tax Reform Legislation on securities available for sale is treated differently for the regulatory capital calculation and financial accounting. For financial accounting purposes, deferred tax provisions for unrealized gains on securities available for sale are recorded directly to other comprehensive income whereas the adjustment to the related deferred tax liabilities for a change in expected effective income tax rates is recorded as an adjustment of income tax expense in current period earnings. The positive impact from the above on retained earnings of the Group from the two important German tax law changes in 1999 and 2000 amounts to approximately € 2.8 billion and € 3.0 billion as of December 31, 2003 and 2002, respectively. For the purpose of calculating the regulatory capital, gross unrealized gains on securities available for sale are excluded from Tier I capital. The adjustment relates to accumulated other comprehensive income (€ (0.9) billion in 2003 and € (2.9) billion in 2002) and the release of deferred tax provisions (€ 2.8 billion in 2003 and € 3.0 billion in 2002) included in retained earnings.

In 2003, our risk position decreased by € 21.8 billion to € 215.7 billion on December 31, 2003. The decrease was driven by several factors, mainly the Euro appreciation and reductions in participating interests and tangible assets.
BIS rules and the German Banking Act require us to cover our market price risk as of December 31, 2003, with slightly over € 762 million of regulatory capital (Tier I + II + III). We met this requirement entirely with Tier I and Tier II capital.
Our U.S. GAAP-based total regulatory capital was € 29.9 billion on December 31, 2003, and our core capital (Tier I) was € 21.6 billion, compared to € 29.9 billion and € 22.7 billion on December 31, 2002. Our supplementary capital (Tier II) of € 8.3 billion on December 31, 2003, amounted to 38% of our core capital.
Our capital ratio was 13.9% on December 31, 2003, significantly higher than the 8% minimum required by the BIS guidelines. Our core capital ratio was 10.0% in relation to the total risk position (including market risk equivalent).
Failure to meet minimum capital requirements can initiate certain mandates, and possibly additional discretionary actions by the German Federal Financial Supervisory Authority and other regulators that, if undertaken, could have a direct material effect on the consolidated financial statements of the Group.
