Article 4 4.

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.
