Risk categories of comdirect

We classify risks in line with the German Accounting Standard DRS 5-10 and distinguish between market risk, credit risk, liquidity and operational risk. The other risks are business risk and model risk, which are additionally classified as material types of risk and included in the risk-bearing capacity analysis. Reputation risk also represents a material type of risk, but as a non-quantifiable risk is managed on a purely qualitative basis and not backed by economically required capital as part of the ICAAP.

A market risk describes the potential loss on positions in the bank’s own portfolio caused by future market price fluctuations. A distinction is made between general changes in market prices and a specific market risk related to individual financial instruments. With regard to risk factors, we distinguish between interest rate, credit spread, equity price and currency risks. The main market risks for comdirect are the interest rate risk and the credit spread risk in the banking book. The interest rate risk arises in particular from maturity transformations, i.e. the mismatching of fixed interest rates on assets and liabilities. The credit spread risk results from changes in risk premiums on bonds against a low risk reference interest rate. Hedged items essentially comprise bonds and promissory notes as well as money market transactions with other financial institutions, which are used for the investment of surplus customer deposits. If required, interest rate swaps and forward rate agreements are concluded for the purposes of hedging and general interest book management.

The credit risk describes the risk of a financial loss which arises when a borrower is unable to pay or to pay on time the contractually agreed consideration. This primarily includes counterparty and issuer risks arising from business involving money market and capital market transactions, as well as credit risks in retail business.

Liquidity risk in the narrower sense is understood as the risk that the bank will be unable to meet or to meet on time its current and future payment obligations. The broader definition of liquidity risk also encompasses refinancing risk, which is the risk that the liquidity will not be sufficient if required or that it can only be acquired in the money and capital markets at terms that are significantly less favourable than expected, as well as market liquidity risk. The latter describes the risk of being unable to unwind or close out securities positions to the desired extent or only at a loss as a result of inadequate market depth or market disruptions. The liquidity risk is a material risk for comdirect and is adequately taken into account in the risk management and controlling processes. Nevertheless, the liquidity risk is not included in the risk-bearing capacity analysis, since in line with the definition chosen, it cannot be usefully limited through economic capital.

Operational risk is understood as possible losses resulting from the use of operating processes and systems that are inappropriate or susceptible to failure as well as human error and external events such as natural disasters or terrorist attacks. Furthermore, operational risks comprise the legal risks resulting from contractual agreements or a change to legal framework parameters. Personnel risks are also classified as operational risks. These essentially comprise the potential loss of personnel in key positions, who play a major role in comdirect's success.

Reputation risk is understood as the risk of the public or customers losing confidence in the bank as a result of negative events in the course of its operating activities. Such risks often arise as secondary effects resulting from operational risks such as those relating to IT, compliance or legal risks.

Business risk encompasses possible losses from negative deviations from plans which can result, for example, from changes in market parameters and competitive behaviour or from incorrect planning.

The model risk describes the risk of losses from the early sale of Treasury investments in response to unexpectedly high deposit outflows.

Risk measurement concepts

To measure the risk situation we use both the expected loss and the unexpected loss in various market scenarios.

The expected loss describes the loss that can be expected within a year based on empirical values, for example on past losses. We calculate this figure for credit risks and operational risks.

We determine the unexpected loss on a regular basis and aggregate it to form the overall risk position; this includes market risk, model risk, credit risk and operational risk as well as business risk. The overall risk position is measured uniformly using the economic capital required, i.e. the amount of capital that has to be maintained to cover unexpected losses from positions involving risk at a given probability within a year. This calculation also includes risk categories that do not require equity backing under banking regulations or do not require full capital backing, but which, from an economic viewpoint, represent potential material risk (market risks, model risks and business risks).

comdirect adopts a very conservative approach when calculating the economic capital required using the value-at-risk (VaR) approach. On the one hand, we generally use a confidence level of 99.91% with a holding period of one year when calculating the VaR. On the other, with regard to the aggregation of the individual types of risk to form the overall risk position, comdirect bank does not take into account any correlations that have a risk-mitigating effect.

The overall risk position is matched by the risk cover potential, which comprises the subscribed capital, open reserves (capital and retained earnings), the (forecast) after-tax profit and the revaluation reserve after tax. Other intangible assets such as licences to use software or internally generated software and deferred taxes are deducted from the risk cover potential as adjustment items. The risk-bearing capacity is guaranteed when utilisation of the risk cover potential by comdirect’s overall risk position stands at less than 100%. Countermeasures are initiated as soon as the utilisation level reaches the defined early warning thresholds. Corresponding early warning thresholds are also defined for each type of risk.

The value-at-risk model indicates the potential loss under historically observed market conditions. In order to assess potential extreme market developments as well, we carry out additional stress tests.

Integrated stress tests that cover all the types of risk are an integral part of comdirect’s risk management and ICAAP process. They are used to examine the resilience of comdirect’s portfolio under extreme, but plausible, scenarios that have a low probability of occurrence. To carry out the integrated stress tests, comdirect uses macroeconomic scenario analyses in accordance with MaRisk. These are applied at comdirect group level. They include all risks that are deemed material in accordance with the risk inventory carried out on a regular basis. As well as determining the economic capital required, the results of the integrated stress tests are taken into account and limited as part of the risk-bearing capacity analysis.

In addition to the macroeconomic stress tests, we carry out specific stress tests for each type of risk as part of operational management. These take into consideration both historical and hypothetical extreme events. The third type of stress test carried out is the inverse stress test in accordance with MaRisk. Based on the sensitivity and scenario analyses, extreme events are identified for each type of risk that would jeopardise the existence of comdirect if they occurred. The aim of these analyses is to critically assess the results and any associated potential implications for the business model and risk management of comdirect.
