By the term Advanced Measurement Approach (AMA) or also the advanced measuring beginning is understood in the banking an instrument for the measurement of the operational risk in Kreditinstitut.

Classification

For the AMA, contrary to the basis indicator beginning and the standard beginning, no firm procedures for the computation of the operational risk are given. In place of these defaults there is an extensive requirement catalog, which represents an extension of the requirement catalog for the standard beginning. Around the AMA to use to be allowed all requirements of the requirement catalog must be fulfilled. Finally the AMA is based on internal computation methods which can be chosen from each Kreditinstitut for the determination of the own resources deposit. In addition there is for example the loss distribution beginning or Scorecard of goals of the AMA can after the goals of the credit institutes and the goals of the Basler of committee be partitioned.

Goals of the credit institutes

For credit institutes the implementation "„of the expensive "“advanced beginning has primarily surely the reduction of own capital funds, contrary to application "„more simply "“beginnings, which can be deposited, as a goal. Accompanying with it however, not only the regulatorischen background to regard, but also from the Basler the committee planned is recommended to use economic aspects.

Goals of the Basler committee

The AMA offers greatest possible clearance to credit institutes with the measurement of operational risks, in one by requirement catalogs defined frameworks. The Basler pursues committee, according to own data to take part with the creation of such a measuring beginning the goal, credit institutes actively in the innovation in the area of the measurement of operational risks:

Here with regard to the future the questions can be placed whether and when the Basler committee prescribes appropriate procedures for the advanced beginning and will have which influence such a definition on the use of the simple procedures.

Categorization of the AMA

As already represented, there is no standard technique for the advanced measuring beginning. The Basler committee refers nevertheless to studies of the Risk management Group (RMG), in which it divided the different beginnings by questionings from industrial enterprises in three main categories for the measurement of operational risks:

Internal Measurement Approaches (IMA)

With internal measuring beginnings credit institutes calculate the capital for risks, on acceptance for expected losses, which can be deposited, by operational risks. That means the fact that of a steady relation between expected and unexpected losses is gone out. Can be proceeded both with a linear relationship and from a nonlinear relationship. First implies that the own capital funds deposit results from a multiples of the expected loss, and the latter requires more complex functions for the computation of own capital funds which can be deposited. Sets of rules after the IMA beginning divide the risk endangerment into divisions and risk event types. That means that the risk for each division and type of risk event is quantified individually. Typically the expected loss is determined by combination of estimated loss frequency and estimated of different division risk combinations.

Loss Distributed Approaches (LDA)

With the loss distribution beginning credit institutes for each particular or groups of division risk combinations estimate the prospective distribution over future Zeitraum.Die own resources deposit be based here on a high Wahrscheinlichkeitsdichte of a loss frequency distribution. With the LDA, the spreading loss frequency distribution is based on acceptance over the prospective number and height of arising risk events. Both the distribution of the number and the distribution of the height of loss events are thus included also. However that both are independently regarded, its own distribution function must be considered to illustrate thus in each case. Here different distribution functions for each individual acceptance can be used. Naturally here a poisson distribution (discrete probability distribution) for the number and a logarithmic normal distribution for the height of the loss events could be used. The main difference between the LDA and the IMA is the fact that the LDA aims at rather a direct estimation of unexpected losses, during the IMA tries the loss estimation by acceptance over the relations losses unexpected expected by linear relationship and nonlinear relationship, and to estimate.

Scorecard Approaches

With this beginning credit institutes set a starting sum of own capital funds for operational risks and modify the height occasionally on the basis of Scorecards. The goal of the Scorecards is the collection of the risk profile and the risk price increase surrounding field of different divisions and a future-referred risk price increase for the minimization of the number and height of risk events arising in the future.
