(3)The nature of an economic downturn for a given type of exposures should be specified by reference to the set of economic indicators that are considered to be either explanatory variables for, or indicators of, the economic cycle specific to that type of exposures. The set of economic indicators should include both macro-economic and credit-related indicators. This is to ensure that, for a comparable type of exposures, institutions will, generally speaking, identify the same economic downturn.
