Position risk on a traded debt instrument or equity instrument or derivative thereof may be divided into two components for purposes of this Chapter. The first shall be its specific risk component and shall encompass the risk of a price change in the instrument concerned due to factors related to its issuer or, in the case of a derivative, the issuer of the underlying instrument. The general risk component shall encompass the risk of a price change in the instrument due in the case of a traded debt instrument or debt derivative to a change in the level of interest rates or in the case of an equity or equity derivative to a broad equity-market movement unrelated to any specific attributes of individual securities.
1.After having verified an institution's compliance with the requirements of Sections 2, 3 and 4 as relevant, competent authorities shall grant permission to institutions to calculate their own funds requirements for one or more of the following risk categories by using their internal models instead of or in combination with the methods in Chapters 2 to 4:
(a)general risk of equity instruments;
(b)specific risk of equity instruments;
(c)general risk of debt instruments;
(d)specific risk of debt instruments;
(e) foreign-exchange risk;
(f)commodities risk.
2.For risk categories for which the institution has not been granted the permission referred to in paragraph 1 to use its internal models, that institution shall continue to calculate own funds requirements in accordance with those Chapters 2, 3 and 4 as relevant. Permission by the competent authorities for the use of internal models shall be required for each risk category and shall be granted only if the internal model covers a significant share of the positions of a certain risk category.
3.Material changes to the use of internal models that the institution has received permission to use, the extension of the use of internal models that the institution has received permission to use, in particular to additional risk categories, and the initial calculation of stressed value-at-risk in accordance with Article 365(2) require a separate permission by the competent authority.
Institutions shall notify the competent authorities of all other extensions and changes to the use of those internal models that the institution has received permission to use.
4.[F1The [F2PRA may] make technical standards] to specify the following:
(a)the conditions for assessing materiality of extensions and changes to the use of internal models;
(b)the assessment methodology under which [F3it permits] institutions to use internal models;
(c)the conditions under which the share of positions covered by the internal model within a risk category shall be considered significant as referred to in paragraph 2.
