Validation and Reconstruction of Internal Rating Systemss

1. Simple Internal Rating Validation Service

For improving the credit risk management of members, CRD Association provides a simple internal rating validation service.

Rating Mapping Analysis

In this service, CRD Association uses its model to evaluate the internal rating system of members to ensure it is constructed and managed properly. In internal rating systems, it is important that each rating is ranked accurately and grouped according to the credit risk of borrowers. Rating mapping analysis compares the evaluations by the internal rating systems of members and those by the CRD model. As part of the comparison, the accuracy of the internal rating models of CRD members is checked. Furthermore, several reports investigating the internal rating models are provided.

What is "CRD rank"?

The CRD rank comprises 10 ranks that divide the financial statements of borrowers in the CRD by the predicted probability of default estimated by the CRD model. The CRD rank lies between 1 (low risk) and 10 (high risk) and is updated each year.

Creation of Rating Transition Matrix

By comparing ratings in the previous term and those in the current term, and identifying any changes of ratings, CRD Association validates the stability and accuracy of the rating system.

Estimation of the AR value

By validating rating models in a comparison with the CRD model, CRD Association offers not only relative validations of credit-rating systems, but also helps members understand the characteristics of rating models.

If members provide sufficient client data, CRD Association can estimate AR values for the financial rating, temporal rating, and final rating.

2. Support Services for Reconstruction of Internal Rating System

Extraction and summarization of current problems in a credit-rating system.

To reconstruct a credit-rating system, it is necessary to check the current credit-rating system, credit-rating process, and extraction and summarization of current problems.

Consideration of direction for reconstruction of credit rating

Based on the results of the extraction and summarization, this service considers the direction of reconstruction for an optimal credit-rating system using the following steps.

Step 1: Extraction and summarization of current problems.

Step 2: Validation of accuracy of financial statement evaluation model.

Development of database

- Validation of accuracy of internal rating model

- Validation of results of internal rating

- Validation of framework of an internal rating system

Step 3

(1): Minor change of internal rating system

- Adjustment of the evaluation model for financial statements

- Reconsideration of a part of the internal-rating framework

(2): Reconstruction of internal rating system

- Reconsideration of quantitative and qualitative evaluations

- Reconsideration of combination of evaluations

- Reconstruction of framework of internal rating system

3. Rating and Self-assessment Support System

Outline of the system

Utilizing the CRD model, CRD Association sells "Rating and self-assessment support systems" to CRD members. This system was developed by CRD Association and Fujitsu Mission Critical Systems.

  • In this system, efficient credit management is realized by integration of credit ratings estimated by the CRD model and self-assessment.
  • In this system, the stability and soundness of financial institutions are improved and advanced credit-risk management is realized by low cost.

Features of the System

i. Systematization of Rating and Self-assessment and Credit Risk Management Business Processes

  • This system realizes integration of rating and self-assessment by providing credit ratings, determining debt ratings, and estimating the amount of debts.
  • This system supports standard loan rates corresponding to internal ratings.
  • This system cooperates with the write-off and loan-loss provision system.
  • This system cooperates effectively with the cost accounting system and the earnings management system.

ii. Corresponding to Basel II

  • By using the CRD scoring model, members are able to estimate the probability of default of borrowers and internal ratings, which is required by Basel II.
  • This system supports the estimation of the probability of default for each internal rating corresponding to Basel II.

iii. Promotion of Rationalization in Business Processes Corresponding to Basel II

  • By digitization of the workflow of applications and approvals, paperless business processes are realized.
  • By integrating credit ratings and self-assessments, efficient business processes are facilitated.

iv. Utilization Promotion for Management

  • A head office can check the state of internal ratings and self-assessments in real time.
