Under the Basel II guidelines, banks are allowed to use their own estimated risk parameters for the purpose of calculating regulatory capital. This is known as the internal ratings-based approach to capital requirements for credit risk. Only banks meeting certain minimum conditions, disclosure requirements and approval from their national supervisor are allowed to use this approach in estimating capital for various exposures. The internal ratings-based approach to credit risk allows banks to model their own inputs for calculating risk-weighted assets from credit exposures to retail, corporate, financial institution and sovereign borrowers, subject to supervisory approval. Under foundation IRB, banks model only the probability of default.
