Grandfathering of capital instruments

This question concerns two types of non-innovative Hybrid Tier 1 instruments (both issued before 31 December 2011): -- Type A: securities with first call date occurred in year 5, and before 31 December 2012; -- Type B: securities with first call date occurred in year 5, and after 31 December 2012. Questions: 1. For both A and B, is it correct to follow Article 484(4) & Article 486(3) for grandfathering guidelines? 2. For both A and B, is it correct to assume that the amount in excess of the applicable Tier 1 grandfathering percentage limit will be treated as grandfathered Tier 2 capital, i.e. being subject to the Tier 2 cap, as per Article 487(2)? 3. Alternatively, for both A and B, can the amount in excess of the applicable Tier 1 grandfathering percentage limit be treated as Tier 2 in full from 1 January 2014? Since they are meeting all the criteria for Tier 2 capital under Regulation (EU) No. 575/2013, as per Article 63 post the call date?

Many issuers have non-step Tier 1 outstanding.
