DBRS Morningstar Upgrades 12 European Structured Finance Transactions, Following Portugal Sovereign Rating Upgrade

DBRS Ratings GmbH and DBRS Ratings Limited (together, DBRS Morningstar) upgraded 12 tranches across 12 Portuguese structured finance transactions. The upgrades reflect the Republic of Portugal’s (Portugal) Long-Term Foreign and Local Currency – Issuer Rating upgrade to BBB (high) with a Stable trend, from BBB with a Positive trend, on 4 October 2019 (see DBRS Morningstar’s press release titled “DBRS Morningstar Upgrades Republic of Portugal to BBB (high), Stable Trend”).

Following the rating action on the sovereign, the ratings of ten tranches across ten RMBS transactions have been upgraded by one notch, while one tranche of one SME transaction was upgraded by two notches. Lastly, one tranche of one Portuguese electricity tariff securitisation was upgraded by one notch, given the link between the performance of this transaction and the creditworthiness of the Portuguese sovereign.

DBRS Morningstar reviewed the impact of the reduced country risk for all the transactions in accordance with “Appendix C: The Impact of Sovereign Ratings on Other DBRS Credit Ratings” of the “Global Methodology for Rating Sovereign Governments” methodology at: https://www.dbrs.com/research/350410/global-methodology-for-rating-sovereign-governments.

Additionally, the reviews of the transactions incorporated the following analytical considerations:

-- Portfolio performance, in terms of delinquencies and defaults, as of the latest payment date for each transaction;
-- Probability of default (PD), loss given default (LGD) and expected loss assumptions on the remaining collateral portfolios; and
-- Current available credit enhancement to the rated notes to cover the expected losses at their respective rating levels.

DBRS Morningstar structured finance ratings within countries belonging to a monetary union may be up to three rating categories above the sovereign (e.g., from BBB to AAA). Following the sovereign upgrade, DBRS Morningstar adjusted the additional stresses applied to account for potential currency depreciation and capital controls in the unlikely scenario of a Portuguese euro zone exit.

The complete list of ratings affected can be found at the end of this press release.

Notes:
All figures are in euros unless otherwise noted.

The principal methodology applicable to the ratings is the “Master European Structured Finance Surveillance Methodology”, except for Lusitano SME No. 3 where the principal methodology applicable to the rating is the “Rating CLOs Backed by Loans to European SMEs” methodology. DBRS Morningstar has applied the principal methodology consistently and conducted a review of the transactions in accordance with the principal methodology.

A review of the transactions legal documents was not conducted as the legal documents have remained unchanged since the most recent rating actions for each transaction.

Other methodologies referenced in these transactions are listed at the end of this press release.

These may be found on www.dbrs.com at: http://www.dbrs.com/about/methodologies.

Atlantes Mortgage N º 2

DBRS Morningstar upgraded its rating on the Class A Notes issued by Atlantes Mortgage N º 2 to AA (high) (sf) from AA (sf) following a review of the transaction prompted by the DBRS Morningstar sovereign upgrade of Portugal on 4 October 2019.

The sources of data and information used for the rating on Atlantes Mortgage N º 2 include investor reports provided by HSBC Bank plc and loan-level data from the European DataWarehouse GmbH.

The last rating action on this transaction took place on 9 August 2019 when DBRS Morningstar confirmed its rating at AA (sf).

The lead analyst responsibilities for this transaction have been transferred to Daniele Canestrari.

To assess the impact of changing the transaction parameters on the rating, DBRS Morningstar considered the following stress scenarios as compared with the parameters used to determine the rating (the Base Case):

-- DBRS Morningstar expected a lifetime base case PD and LGD for the pool based on a review of the current assets. Adverse changes to asset performance may cause stresses to base case assumptions and therefore have a negative effect on credit ratings.
-- The risk sensitivity overview below illustrates the ratings expected if the PD and LGD increase by a certain percentage over the base case assumption. For example, if the LGD increases by 50%, the rating of the Class A Notes would be expected to remain at AA (high) (sf), ceteris paribus. If the PD increases by 50%, the rating of the Class A Notes would be expected to decrease to A (low) (sf), ceteris paribus. Furthermore, if both the PD and LGD increase by 50%, the rating of the Class A Notes would be expected to decrease to A (low) (sf).

Class A Notes Risk Sensitivity:
-- 25% increase in LGD, expected rating of AA (high) (sf)
-- 50% increase in LGD, expected rating of AA (high) (sf)
-- 25% increase in PD, expected rating of A (high) (sf)

The last rating action on this transaction took place on 5 April 2019 when DBRS Morningstar confirmed its rating on the Class A Notes at AA (high) (sf).

To assess the impact of changing the transaction parameters on the rating, DBRS Morningstar considered the following stress scenarios as compared with the parameters used to determine the rating (the Base Case):

-- DBRS Morningstar expected a lifetime base case PD and LGD for the pool based on a review of the current assets. Adverse changes to asset performance may cause stresses to base case assumptions and therefore have a negative effect on credit ratings.
-- The Risk Sensitivity overview below illustrates the ratings expected if the PD and LGD increase by a certain percentage over the base case assumption. For example, if the LGD increases by 50%, the rating of the Class A Notes would be expected to remain at AAA (sf), ceteris paribus. If the PD increases by 50%, the rating of the Class A Notes would be expected to remain at AAA (sf), ceteris paribus. Furthermore, if both the PD and LGD increase by 50%, the rating of the Class A Notes would be expected to remain at AAA (sf).

Class A Notes Risk Sensitivity:
-- 25% increase in LGD, expected rating of AAA (sf)
-- 50% increase in LGD, expected rating of AAA (sf)
-- 25% increase in PD, expected rating of AAA (sf)
-- 50% increase in PD, expected rating of AAA (sf)
-- 25% increase in PD and 25% increase in LGD, expected rating of AAA (sf)
-- 25% increase in PD and 50% increase in LGD, expected rating of AAA (sf)
-- 50% increase in PD and 25% increase in LGD, expected rating of AAA (sf)
-- 50% increase in PD and 50% increase in LGD, expected rating of AAA (sf)

Volta IV Electricity Receivables Securitisation (Volta IV)

DBRS Morningstar upgraded its rating on the Senior Notes issued by Volta IV Electricity Receivables Securitisation to A (sf) from A (low) (sf) following the DBRS Morningstar sovereign upgrade of Portugal on 4 October 2019, given the specific nature of this asset class, with strong linkage between the performance of the sovereign and the performance of securities issued by Portuguese electricity tariff transactions.

Based on DBRS Morningstar’s “Rating Portuguese Electricity Tariff Securitisations” methodology, the ratings on securities issued by Portuguese electricity tariff transactions are limited to a two-notch increase above the current local currency sovereign rating of Portugal.

The sources of data and information used for the rating on Volta IV include investor reports provided by Citibank N.A., London branch.

The last rating action on this transaction took place on 9 May 2019 when DBRS Morningstar confirmed the rating of the Senior Notes at A (low) (sf).

The lead analyst responsibilities for this transaction have been transferred to Petter Wettestad.

To assess the impact of changing the transaction parameters on the rating, DBRS Morningstar considered several sovereign downgrade stress scenarios as compared to the current rating (the Base Case):

-- A hypothetical downgrade of the sovereign rating of Portugal by one notch, ceteris paribus, would lead to a decrease in the rating of the Senior Notes to A (low) (sf).
-- A hypothetical downgrade of the sovereign rating of Portugal by two notches, ceteris paribus, would lead to a decrease in the rating of the Senior Notes to BBB (high) (sf).
