Article 503
1.
The Commission shall, by 31 December 2014, after consulting EBA, report to the European Parliament and to the Council, together with any appropriate proposals, on whether the risk weights laid down in Article 129 and the own funds requirements for specific risk in Article 336(3) are adequate for all the instruments that qualify for these treatments and whether the criteria in Article 129 are appropriate.
2.
The report and the proposals referred to in paragraph 1 shall take into account:
(a)
the extent to which the current regulatory capital requirements applicable to covered bonds adequately differentiate between variances in the credit quality of covered bonds and the collateral against which they are secured, including the extent of variations across Member States;
(b)
the transparency of the covered bond market and the extent to which this facilitates comprehensive internal analysis by investors in respect of the credit risk of covered bonds and the collateral against which they are secured and the asset segregation in case of the issuer's insolvency, including the mitigating effects of the underlying strict national legal framework in accordance with Article 129 of this Regulation and Article 52(4) of Directive 2009/65/EC on the overall credit quality of a covered bond and its implications on the level of transparency needed by investors; and
(c)
the extent to which covered bond issuance by a credit institution impacts on the credit risk to which other creditors of the issuing institution are exposed.
3.
The Commission shall, by 31 December 2014, after consulting EBA, report to the European Parliament and the Council on whether loans secured by aircrafts (aircraft liens) and residential loans secured by a guarantee but not secured by a registered mortgage, should under certain conditions be considered an eligible asset in accordance with Article 129.
4.
The Commission shall, by 31 December 2016, review the appropriateness of the derogation set out in Article 496 and, if relevant, the appropriateness of extending similar treatment to any other form of covered bond. In the light of that review, the Commission may, if appropriate, adopt delegated acts in accordance with Article 462 to make that derogation permanent, or make legislative proposals to extend it to other forms of covered bonds.
