DBRS Morningstar Assigns AA Credit Rating to Santander Totta S.A. Covered Bonds (Obrigações Cobertas - Mortgages) Series 30

DBRS Ratings GmbH (DBRS Morningstar) assigned a AA credit rating to the Series 30 (ISIN PTBSPCOM0006) Obrigações Cobertas (formerly designated Obrigações Hipotecárias; the Portuguese legislative covered bonds) issued under the Banco Santander Totta S.A. (Totta or the Issuer) EUR 12.5 billion programme (the programme).

Series 30 is a EUR 850 million fixed-rate bond that pays a coupon of 3.750% and matures on 11 September 2026.

Following the issuance of Series 30, there are 11 series of covered bonds (CBs) outstanding under the programme, totalling a nominal amount of EUR 9.70 billion. All CBs issued under the programme rank pari passu with each other and DBRS Morningstar currently rates them AA.

The credit rating is based on the following analytical considerations:
-- A Covered Bonds Attachment Point (CBAP) of A (high). Totta is the Issuer of and Reference Entity for the programme. There is no Critical Obligations Rating (COR) assigned to Totta, but DBRS Morningstar considers Portugal a jurisdiction for which CBs are a particularly important financing tool. As such, the CBAP is set at the level of the Issuer Rating plus one notch.
-- A Legal and Structuring Framework (LSF) Assessment of “Strong” associated with the programme.
-- A Cover Pool Credit Assessment (CPCA) of BBB (low), which is the lowest CPCA in line with the LSF-Implied Likelihood (LSF-L).
-- An LSF-L of AA (low).
-- A one-notch uplift for good recovery prospects.
-- A committed minimum overcollateralisation (OC) of 15%. DBRS Morningstar gives full credit to such commitment in accordance with its principal methodology. Such level is not subject to a haircut as DBRS Morningstar considers it to be persistent based on historically observed levels.
-- The sovereign rating on the Republic of Portugal, rated “A” with a Stable trend by DBRS Morningstar as of the date of this press release.

DBRS Morningstar analysed the transaction using its European Covered Bond Cash Flow tool. The main assumptions focused on the timing of defaults and recoveries of the assets, interest rate stresses, and market value spreads to calculate liquidation values on the cover pool (CP).

Everything else being equal, a one-notch downgrade of the CBAP would lead to a one-notch downgrade of the LSF-L, resulting in a one-notch downgrade of the CB ratings.

In addition, all else unchanged, the CB ratings would be downgraded if any of the following occurred: (1) the CPCA was downgraded to below BBB (low); (2) the sovereign rating on the Republic of Portugal was downgraded to below A (low); (3) the LSF Assessment associated with the programme was downgraded; (4) the quality of the CP and the level of OC were no longer sufficient to support a one-notch uplift for good recovery prospects; (5) the relative amortisation profile of the CBs and the CP moved adversely; or (6) volatility in the financial markets caused the currently estimated market value spreads to increase.

For further information on the programme, please refer to the rating report at www.dbrsmorningstar.com.

The vast majority of the loans in the CP (99%) are floating rate, indexed to different bases, and they reset at different times, while all CB series are fixed rate. The resulting interest rate mismatch is mitigated by intra-group swap agreements that contain downgrade and collateral-posting language in line with DBRS Morningstar’s criteria and have been given full credit in DBRS Morningstar’s analysis.

The DBRS Morningstar-calculated weighted-average (WA) life of the mortgage assets is about 17 years based on a 0% prepayment rate, which is longer than the 4.2 years of WA life on the CBs, not accounting for any maturity extension. This risk is mitigated by the extended maturity dates, which fall one year after the maturity dates, and by the OC in place.

All CP assets and CB are denominated in euros. As such, investors are not currently exposed to any foreign exchange risk.

DBRS Morningstar has assessed the LSF related to the programme as “Strong” according to its rating methodology. For more information, please refer to DBRS Morningstar’s publication “Portuguese Covered Bonds: Legal and Structuring Framework Review”, available at www.dbrsmorningstar.com.

DBRS Morningstar’s credit rating on Series 30 addresses the credit risk associated with the identified financial obligations in accordance with the relevant transaction documents.

DBRS Morningstar’s credit rating does not address non-payment risk associated with contractual payment obligations contemplated in the applicable transaction documents that are not financial obligations.

DBRS Morningstar’s long-term credit ratings provide opinions on risk of default. DBRS Morningstar considers risk of default to be the risk that an issuer will fail to satisfy the financial obligations in accordance with the terms under which a long-term obligation has been issued.
