Because the value at risk concept forecasts potential losses<br />

under normal market conditions, Commerzbank also calculates<br />

stress tests to cover possible extreme scenarios. Stress tests are<br />

intended to simulate the impact of crises and extreme market<br />

conditions.<br />

Stress tests performed across portfolios simulate the impact<br />

of historical and conceivable future crisis scenarios on the Group<br />

(86) Interest rate risk<br />

The interest rate risk of the Commerzbank Group results from<br />

items in both the trading book and the banking book. In the<br />

latter, interest rate risk mainly arises through maturity<br />

mismatches between the Bank’s interest-bearing assets and<br />

liabilities - for instance, through the short-term funding of longdated<br />

loans. The interest rate items shown in the balance sheet<br />

as well as the derivatives employed to manage them are<br />

included in the measurement of interest rate risk.<br />

The interest rate risks at Group level are currently measured<br />

using a net present value approach.<br />

The impact of an interest rate shock on the economic value of<br />

the Group’s banking books is simulated monthly in compliance<br />

with regulatory requirements. In accordance with the Banking<br />

(87) Operational risk<br />

Operational risk (OpRisk) at Commerzbank is based on the<br />

German Solvency Regulation (SolvV) and is defined as the risk of<br />

loss resulting from the inadequacy or failure of internal<br />

processes and systems, people or from external events. This<br />

definition includes legal risks; it does not cover reputational<br />

risks or strategic risks.<br />

The Operational Risk Committee is kept regularly informed<br />

about the risk situation. It deals in particular with the<br />

management of operational risks within the Group. The aim is to<br />

optimise the expected loss from OpRisk from a cost-benefit<br />

perspective and to minimise the potential for unexpected loss. In<br />

so doing, the Operational Risk Committee takes an end-to-end<br />

view of the processes within the Bank with the aim of<br />

recognising risks in a timely manner. The Operational Risk<br />

Committee also deals with all issues relating to the<br />

as a whole. The overall picture is rounded off by monthly<br />

specific scenario analyses for each asset class (e.g. hypothetical<br />

interest rate, equity, foreign exchange and credit spread<br />

scenarios).<br />

Stress tests by division, adjusted to the risk factors of the<br />

individual portfolios, are also used.<br />

Directive, the Federal Financial Supervisory Authority (BaFin)<br />

has prescribed a uniform unexpected change in interest rates to<br />

be used by all banks, which have to report on the results of this<br />

stress test every quarter.<br />

BaFin amended the change in interest rates to be used to<br />

+200 basis points and –200 basis points at the end of 2011. The<br />

+200 basis point scenario produced a potential loss of €2,052m<br />

and the –200 basis point scenario a potential profit of €1,829m.<br />

These figures include the exposures of Commerzbank<br />

Aktiengesellschaft together with the subsidiaries Eurohypo<br />

Aktiengesellschaft and comdirect bank Aktiengesellschaft. The<br />

Bank was well below the defined threshold for a potential<br />

decline in equity (20% for “outlier” banks).<br />

implementation of AMA (the Advanced Management Approach)<br />

in the Group and arising from the Minimum Requirements for<br />

Risk Management (MaRisk) regulations with regard to<br />

operational risk. It is in particular responsible for the<br />

implementation of the guidelines under section 280 SolvV,<br />

which is the operational responsibility of Group Risk<br />

Control & Capital Management (GRM-CC).<br />

The Group’s operational risk profile, expressed in terms of<br />

the events incurred (losses and provisions) per event category<br />

under section 287 SolvV, shows that around 92% of the losses<br />

fall into the event category of product-related losses. GRM-CC<br />

conducts regular benchmarking of the values to data from the<br />

operational risk data exchange ORX and to public data; these<br />

confirm the high proportion of product-related losses on the<br />

market.<br />
