ENVIRONMENTAL, SOCIAL, GOVERNANCE CONSIDERATIONS
DBRS Morningstar considers that the help-to-buy (HTB) scheme applicable to 23% of the outstanding portfolio is a relevant social factor (social impact of products and services) as outlined in the “DBRS Morningstar Criteria: Approach to Environmental, Social, and Governance Risk Factors in Credit Ratings”. The HTB scheme is credit negative, but DBRS Morningstar does not consider this to be a significant social factor given the limited exposure to HTB loans in this transaction.

There were no Environmental/Governance factors that had a significant or relevant effect on the credit analysis.

A description of how DBRS Morningstar considers ESG factors within the DBRS Morningstar analytical framework can be found in the DBRS Morningstar Criteria: Approach to Environmental, Social, and Governance Risk Factors in Credit Ratings at https://www.dbrsmorningstar.com/research/396929/dbrs-morningstar-criteria-approach-to-environmental-social-and-governance-risk-factors-in-credit-ratings (17 May 2022).

Notes:
All figures are in euros unless otherwise noted.

The principal methodology applicable to the ratings is the “Master European Structured Finance Surveillance Methodology” (19 May 2022).

Other methodologies referenced in this transaction are listed at the end of this press release. These may be found at: https://www.dbrsmorningstar.com/about/methodologies.

In DBRS Morningstar’s opinion, a discontinued-repaid rating action does not warrant the application of the entire principal methodology, as the bond has been repaid in full.
