(19)Excess Common Equity Tier 1 or Additional Tier 1 instruments grandfathered according to the transitional provisions of Regulation (EU) No 575/2013 are, on the basis of these provisions, allowed to be included within the limits for grandfathered instruments for lower tiers of capital. That nevertheless cannot alter the limits for grandfathered instruments for lower tiers, therefore any inclusion in the grandfathering limits of the lower tier should only be possible if there is sufficient allowance in that lower tier. Finally, as those are excess instruments of the higher tier, it should be possible for those instruments to be later reclassified in a higher tier of capital.
