1.1.2. Retail exposures
Rating systems shall reflect both obligor and transaction risk, and shall capture all relevant obligor and transaction characteristics. The level of risk differentiation shall ensure that the number of exposures in a given grade or pool is sufficient to allow for meaningful quantification and validation of the loss characteristics at the grade or pool level. The distribution of exposures and obligors across grades or pools shall be such as to avoid excessive concentrations. Credit institutions shall demonstrate that the process of assigning exposures to grades or pools provides for a meaningful differentiation of risk, provides for a grouping of sufficiently homogenous exposures, and allows for accurate and consistent estimation of loss characteristics at grade or pool level. For purchased receivables the grouping shall reflect the seller's underwriting practices and the heterogeneity of its customers. Credit institutions shall consider the following risk drivers when assigning exposures to grades or pools. Obligor risk characteristics; Transaction risk characteristics, including product or collateral types or both. Credit institutions shall explicitly address cases where several exposures benefit from the same collateral; and Delinquency, unless the credit institution demonstrates to its competent authority that delinquency is not a material risk drivers for the exposure;
