Before revision:  The exposure value as outlined in the IFRS 9 exposure draft (ED 2009)  will be interpreted as an economically justified value under amortized cost accounting and provides the main methodological benchmark . Consequently, the ED 2009 can be used to quantify conservatism (ie  hidden reserves) in the actual implementation of the final standard and to separate operational side-effects caused by the local implementation from actual credit risk impacts.
