Under section VI of the Decree on the Implementation of the Basel II Capital Accord, DNB may reduce the requisite period of experience of the IRB approach from three years to one year (simple IRB) or two years (advanced IRB). The Policy Rule on Relaxation of the IRB Experience Requirement sets out the aspects that are taken into account by DNB in assessing an application for relaxation of the rule.
The Policy Rule serves to implement the Basel II Capital Accord (the recast Banking Directive (2006/48/EC) and the recast Capital Adequacy Directive (2006/49/EC)).
