The relevant authority shall calculate the scores of the relevant entities that are included in the sample notified by the EBA and which are authorised in its jurisdiction not later than 1 September of each year.

Where the relevant authority, in the exercise of sound supervisory judgement, reallocates a G-SII from a lower subcategory to a higher subcategory or designates a relevant entity as a G-SII in accordance with points (a) or (b) of Article 131(10) of Directive 2013/36/EU, respectively, the relevant authority shall provide the EBA with a detailed statement in written form on the reasons for its assessment not later than 1 November of each year.

Where the relevant authority, in the exercise of sound supervisory judgement, reallocates a G-SII from a higher subcategory to a lower subcategory in accordance with point (c) of Article 131(10) of Directive 2013/36/EU, the relevant authority shall provide the EBA with a detailed statement in written form on the reasons for its assessment not later than 30 September of each year.

The reallocation or designation referred to in paragraph 2 shall take effect as of 1 January of the second year following the calendar year in which the denominators have been notified to the relevant authorities in accordance with Article 3(3). Where a G-SII is allocated to a lower subcategory than in the previous year’s identification process, the lower G-SII buffer requirement shall take effect from 1 January of the year following that reallocation, unless the relevant authority exerts its sound supervisory judgement to delay the application of that requirement to the date referred to in the first sentence of this paragraph.

The identification of a relevant entity as a G-SII by the relevant authority shall include the Legal Entity Identifiers (LEIs) of all legal entities included in the prudential scope of consolidation of the G-SII. The relevant entity identified by the relevant authority shall disclose to the relevant authority by 1 March of the year following the year of the identification exercise its group structure by providing the LEIs, where available, of all consolidated entities in the group. The relevant entity shall ensure that its group structure as disclosed through the global LEI database is permanently updated.
