  "text": "ANNEX III\nExtensions and changes to the IMA\nPART I\nEXTENSIONS TO THE IMA\nSection 1\nExtensions requiring competent authorities' approval (“material”)\n1.\nExtension of the market risk model to an additional location in another jurisdiction, including extending the market risk model to the positions of a desk located in a different time zone, or for which different front office or IT systems are used.\n2.\nIntegration in the scope of an IMA model of product classes, for which the VaR number, computed according to Article 364(1)(a)(i) of Regulation (EU) No 575/2013, exceeds 5 % of the VaR number, computed according to Article 364(1)(a)(i) of Regulation (EU) No 575/2013, of the total portfolio forming the scope of that IMA model before the integration.\n3.\nAny reverse extensions such as cases where the institutions aim at applying the standardized method to risk categories for which they are granted permission to use an internal market risk model.\nSection 2\nExtensions requiring ex ante notification to competent authorities\nThe inclusion in the scope of an IMA model of product classes requiring other risk modelling techniques than those forming part of the permission to use that IMA model, such as path-dependent products, or multi-underlying positions, according to Article 367 of Regulation (EU) No 575/2013.\nPART II\nCHANGES TO THE IMA\nSection 1\nChanges requiring competent authorities' approval (“material”)\n1.\nChanges between historical simulation, parametric or Monte Carlo VaR.\n2.\nChanges in the aggregation scheme such as where a simple summation of risk numbers is replaced by integrated modelling.\nSection 2\nChanges requiring ex ante notification to competent authorities\n1.\nChanges in the fundamentals of statistical methods according to Articles 365, 374 or 377 of Regulation (EU) No 575/2013, including but not limited to any of the following:\n(a) reduction in the number of simulations;\n(b) introduction or removal of variance reduction methods;\n(c) changes to the algorithms to generate the random numbers;\n(d) changes in the statistical method to estimate volatilities or correlations between risk factors;\n(e) changes in the assumptions about the joint distribution of risk factors.\n2.\nChanges in the effective length of the historical observation period, including a change in a weighting scheme of the time series according to Article 365(1)(d) of Regulation (EU) No 575/2013.\n3.\nChanges in the approach for identifying the stressed period in order to calculate a Stressed VaR measure, according to Article 365(2) of Regulation (EU) No 575/2013.\n4.\nChanges in the definition of market risk factors applied in the internal VaR model, including migration to an OIS discounting framework, a move between zero rates, par rates or swap rates.\n5.\nChanges in how shifts in market risk factors are translated into changes of the portfolio value, such as changes in instrument valuation models — used to calculate sensitivities to risk factors or to re-value positions when calculating risk numbers —, changes from analytical to simulation-based pricing model, changes between Taylor-approximation and full revaluation, or changes in the sensitivity measures applied, according to Article 367 of Regulation (EU) No 575/2013.\n6.\nChanges in the methodology for defining proxies.\n7.\nChanges in the hierarchy of sources of ratings used for determining the rating of an individual position in the IRC.\n8.\nChanges in the methodology regarding the loss given default rate (LGD) or the liquidity horizons for IRC or correlation trading models according to Section 4 or Section 5 of Chapter 5 of Title IV of Regulation (EU) No 575/2013.\n9.\nChanges in the methodology used for assigning exposures to individual exposure classes in the IRC or correlation trading models according to Section 4 or Section 5 of Chapter 5 of Title IV of Regulation (EU) No 575/2013.\n10.\nChanges of methods for estimating exposure or asset correlation for IRC or correlation trading models according to Section 4 or Section 5 of Chapter 5 of Title IV of Regulation (EU) No 575/2013.\n11.\nChanges in the methodology for calculating either actual or hypothetical profit and loss when used for back-testing purposes according to Article 366(3) and 369(2) of Regulation (EU) No 575/2013.\n12.\nChanges in the internal validation methodology according to Article 369 of Regulation (EU) No 575/2013.\n13.\nStructural, organisational or operational changes to the core processes in risk management or risk controlling functions, according to Article 368(1) of Regulation (EU) No 575/2013 including any of the following:\n(a) senior staff changes;\n(b) the limit setting framework;\n(c) the reporting framework;\n(d) the stress testing methodology;\n(e) the new product process;\n(f) the internal model change policy.\n14.\nChanges in the IT environment, including any of the following:\n(a) changes to the IT system, which result in amendments in the calculation procedure of the internal model;\n(b) applying vendor pricing models;\n(c) outsourcing of central data collection functions.",
