3. Treatment of Inspection Monitoring and Inspection Results Notice As an inspection targeted at a contractor will be conducted as part of an inspection targeted at a financial institution, etc., inspection monitoring will be conducted and the inspection results notice will be issued with respect to the financial institution, etc. that outsources the operations, not the contractor. 4. Other Other basic approaches, implementation procedures, etc. for inspections targeted at contractors will be executed in accordance with FIBG. |

(1) Credit Risk There are three approaches to measuring credit risk: the standardized approach, the Foundation Internal Ratings-Based Approach (FIRB) and the Advanced Internal Ratings-Based Approach (AIRB). Financial institutions are now able to choose one from the three approaches. (Note) The FIRB and the AIRB are subject to the approval of the FSA. The standardized approach is the simplest approach, which is a modified version of the existing framework. Major points of such modification are as follows: (i) The risk weight for exposures to small- and medium-sized enterprises and individuals is reduced from 100% (in the existing framework) to 75% in consideration of the diversification of risk into small accounts. The risk weight for housing loans is reduced from 50% (in the existing framework) to 35%. (ii) The risk weight for past due loans, which is past due for more than 3 months, is higher than non-past due loans, and could be decreased according to the provisioning rate. (iii) For exposures to corporations, appropriate risk weights can be used according to their creditworthiness. (Risk weights are from 20% to 150% according to the ratings given by eligible ECAIs. However, banks can choose to apply a 100% risk weight to all exposures without using the ECAIs. On the other hand, the IRB approaches are approaches in which financial institutions with advanced risk management system calculate the required capital using risk parameters such as the probability of default (PD) estimated by themselves. In FIRB approach, the financial institution only estimates the PD and uses the internationally-prescribed values for the loss given default (LGD) and the exposure at default (EAD). In AIRB approach, the financial institutions estimate PD, LGD and EAD, and calculate the required capital based on these estimates. In such a framework that allows financial institutions to choose one from the three approaches, financial institutions will be prompted to choose one from various alternatives and advance their risk management system on their own initiative. (2) Operational Risk Operational risk refers to the risk of losses resulting from a failure in internal processes and systems, misconduct, etc. Three options are given to financial institutions for measuring operational risk: the Basic Indicator Approach (BIA), the Standardized Approach (TSA) and the Advanced Measurement Approaches (AMA). (Note) TSA and AMA are subject to the approval of the FSA. In the BIA and TSA, gross income shall be used as an indicator of operational risk, and the required capital shall be calculated by multiplying gross income by a certain factor. In AMA, financial institutions shall calculate the amount of risk through their own measurement approaches based on the experienced losses, etc. and decide the required capital based on the risk amount. 2. The Third Pillar Basel II prescribes the disclosure of the capital adequacy ratio, its breakdown, the calculation methods of each type of risk and other quantitative information, in order to improve the effectiveness of market discipline through the enhancement of disclosure. The draft rule text on the third pillar prescribes the disclosure items and requires the disclosure of information on these items at least twice a year (once a year in the case of small financial institutions other than banks) pursuant to the disclosure requirements under the Banking Law, etc. In addition, it emphasizes financial institutions' efforts toward more frequent (e.g. quarterly) disclosures for encouraging them to disclose their actual circumstances. Moreover, banks adopting the IRB (credit risk) and/or the AMA (operational risk) approaches will need to implement the semi-annual and/or quarterly disclosures in an appropriate manner as a part of the requirements for the approval of such approaches. The same requirement will also apply to internationally-active financial institutions. 3. Eligible External Credit Assessment Institutions (ECAIs) and the Mapping The mapping between the ratings assigned by eligible ECAIs and the risk weights prescribed in the ordinance is a process to determine what risk weights should correspond to the individual rating grades set by each eligible ECAI whose ratings can be used in the standardized approach for credit risk. The mapping, with respect to ECAIs that wish to be eligible, is determined by six qualitative criteria on appropriateness (i.e., objectivity, independency, transparency, disclosure, human resources/organizational structure, and credibility) and other quantitative criteria such as the default rate, which are presented in the "Eligibility of External Credit Assessment Institutions Usable in Basel II" published on March 31, 2005. (For further information on eligible ECAIs and the mapping, please refer to the website of the FSA.) The mapping may be revised, when it is necessary, before the implementation of Basel II at the end of March 2007, for the existing mapping was tentatively published to be in time of the parallel run period which commences at the end of March 2006. 4. "Publication Items of Eligible Ratings to Securitization Transactions in Japan" (Draft) Risk profiles of securitization transactions are apt to be more complicated and various than that of ordinary exposures to corporations. As risk weights on securitization exposure shall be calculated with the ratings by eligible ECAIs in Basel II, such risk weights will vary significantly according to the applied ratings. In the circumstances, it is deemed extremely important to ensure the appropriateness of the ratings that can be used for securitization exposures. However, individual ratings could not be checked thoroughly by the market as it is difficult for third parties to identify the individual securitization transactions in detail. In addition, due to limited historical default data, it is difficult to test the statistical significance of the default rate that is observed in each rating by the experienced default value (for example, three-year cumulative default rate). With such characteristics in mind, Basel II requires that "a rating must be published in an accessible form and included in the ECAI's transition matrix "), for that the appropriateness of ratings to securitization exposures should be ensured through market discipline. The FSA considers that to satisfy the need of publication, it is necessary to make information, of which the extent is that third parties (not stake holders) can assess the appropriateness of external credit assessments, accessible easily to market participants by such means as the website and reports of the eligible ECAIs. Based on the view, the FSA published the individual publication items for public consultation on March 31, 2006. 5. FAQs The FSA summarizes its current approach to facilitate the implementation of Basel II and foster a further advancement of risk management system at each financial institution. The FSA intends to have dialogue actively with financial institutions advancing their risk management system and prompts further advancement of risk management system. In the process, the FSA plans to continue reviewing FAQs and revise, when it is necessary, with the purpose above in mind. |
