  "heading": "The following changes in the algorithms and procedures used for: assigning obligors to obligor grades or pools; for assigning exposures to facility grades or pools; or for quantifying the risk of obligor default or associated loss (‘changes in the rating methodology for IRB systems’):",
  "text": "(a) changes of the modelling approach for assigning an obligor to grades or pools and/or exposures to facility grades or pools according to Article 171(1) and Article 172(1)(a) to (d) of Regulation (EU) No 575/2013;\n(b) changes to the institution's approach to the ‘one-obligor-one-rating principle’ according to Article 172(1)(e) of Regulation (EU) No 575/2013;\n(c) changes in the rating system's assumptions behind ratings relating to the extent by which a change in economic conditions is expected to result in a net migration of a large number of exposures, obligors or facilities across grades or pools of the model, as opposed to migration of only some exposures, obligors or facilities due only to their individual characteristics the measure and significance levels of which are defined by the institution;\n(d) changes to the rating criteria as referred to in Article 170(1)(c) and (e) and Article 170(4) of Regulation (EU) No 575/2013 and/or their weights, sequence or hierarchy, if any of the following conditions are met:\n(i) they change the rank ordering referred to in Article 170(1)(c) and (3)(c) of Regulation (EU) No 575/2013 in a significant manner, the measure and level of which will have been defined by the institution;\n(ii) they change the distribution of obligors, facilities or exposures across grades or pools according to Article 170(1)(d) and (f) and Article 170(3)(b) of Regulation (EU) No 575/2013 in a significant manner, the measure and level of which will have been defined by the institution.\n(e) introduction or withdrawal of an external rating as a primary factor determining an internal rating assignment according to Article 171(2) of Regulation (EU) No 575/2013;\n(f) change in the fundamental methodology for estimating PDs, LGDs including best estimate of expected loss, and conversion factors according to Articles 180, 181 and 182 of Regulation (EU) No 575/2013, including the methodology for deriving a margin of conservatism related to the expected range of estimation errors according to Article 179(1)(f) of Regulation (EU) No 575/2013. For LGDs and conversion factors this includes also changes in the methodology for accounting for an economic downturn according to Articles 181(1)(b) and 182(1)(b) of Regulation (EU) No 575/2013;\n(g) inclusion of additional types of collateral into the LGD estimation according to Article 181(1)(c) to (g) of Regulation (EU) No 575/2013 if their treatment differs from procedures that have already been approved.",
