(7)The systemic significance of each banking group measured by the indicators on a consolidated basis should be expressed as an individual overall score for a certain year measuring its position relative to other entities in the sample. Banks should be identified as G-SIIs and allocated to the sub-categories to which different capital buffer requirements will apply, based on that overall score. When calculating the score as the average of the category scores, each of the five categories should receive a weighting of 20 %. A cap should be applied to the substitutability category for the purpose of calculating the overall score given that, on the basis of an analysis of data until and including the year 2013, that category proved to have a disproportionately high impact on the score for banks that are dominant in the provision of payment, underwriting and asset custody services.
