Starting with the Corep reports of December 2010, pd values of zero should also be entered in the 'breakdown of total exposure assigned to obligor or pools'. This was hitherto not possible for technical reasons. As pd values of zero could not be reported, the total of the exposures on Row 1 did not match the total of the exposures from the breakdown (row 1.1) in a number of columns. (NB: Some reporting institutions assigned a pd other than zero to items with zero pd value so that the total matched). For more information, please refer to your regular contact person at S&I.
