In this and past Fund staff papers on officially supported export credits, quantitative analysis of developments has been based on two statistical sources. One source is the Berne Union Country Reporting Quarterly Return, commonly referred to as the “40 Countries Report,” in which the member agencies of the Berne Union report their outstanding commitments, unrecovered claims, and outstanding offers for each of 40 countries. These data are not available to the public and have been provided to the staff on a confidential basis for its use in analyzing various aggregates for individual debtor countries.
