DBRS Morningstar Upgrades Rating on Thetis Finance No.1

DBRS Ratings GmbH (DBRS Morningstar) upgraded its rating on the Class A Notes issued by Thetis Finance No.1 (the Issuer) to AA (sf) from A (high) (sf).

The rating on the Class A Notes addresses the timely payment of interest and ultimate repayment of principal on or before the legal final maturity date in July 2038.

The upgrade follows an annual review of the transaction and is based on the following analytical considerations:
-- Portfolio performance, in terms of delinquencies, defaults and losses, as of the April 2021 payment date;
-- Probability of default (PD), loss given default (LGD), and expected loss assumptions on the remaining receivables;
-- Current available credit enhancement to the Class A Notes to cover the expected losses at the AA (sf) rating level; and
-- Current economic environment and an assessment of sustainable performance, as a result of the Coronavirus Disease (COVID-19) pandemic.

The transaction is a securitisation of Portuguese auto loans originated and serviced by Banco Credibom, S.A. (Credibom). The transaction was initially structured with a revolving period that terminated in June 2018.

PORTFOLIO PERFORMANCE
As of the April 2021 payment date, loans that were two to three months in arrears represented 0.5% of the outstanding portfolio balance, up from 0.4% in April 2020. The cumulative default ratio, which includes loans more than 90 days in arrears, was 4.2%.

PORTFOLIO ASSUMPTIONS AND KEY DRIVERS
DBRS Morningstar conducted an analysis of the current pool of receivables, including additional coronavirus-related adjustments, and maintained its base case PD assumption at 16.7% and updated its base case LGD assumption to 63.1%.

CREDIT ENHANCEMENT
As of the April 2021 payment date, credit enhancement to the Class A Notes was 68.86%, up from 45.38% in April 2020. Subordination of part of the Class B Notes provides credit enhancement to the transaction.

The transaction benefits from a cash reserve, funded by part of the proceeds from the issuance of the Class B Notes. The cash reserve is currently at the target level of EUR 2.5 million and is available to cover senior fees and Class A Notes interest.

Crédit Agricole Corporate & Investment Bank SA (CA CIB) acts as the account bank for the transaction. Based on the DBRS Morningstar private rating on CA CIB, the downgrade provisions outlined in the transaction documents, and other mitigating factors inherent in the transaction structure, DBRS Morningstar considers the risk arising from the exposure to the account bank to be consistent with the rating assigned to the Class A Notes, as described in DBRS Morningstar's "Legal Criteria for European Structured Finance Transactions" methodology.

DBRS Morningstar analysed the transaction structure in Intex DealMaker.

The Coronavirus Disease (COVID-19) and the resulting isolation measures have caused an economic contraction, leading to sharp increases in unemployment rates and income reductions for many borrowers. DBRS Morningstar anticipates that delinquencies may continue to increase in the coming months for many asset-backed security (ABS) transactions, some meaningfully. The ratings are based on additional analysis and adjustments to expected performance as a result of the global efforts to contain the spread of the coronavirus. For this transaction, DBRS Morningstar applied an additional haircut to its expected recovery rate and conducted additional sensitivity analysis to determine that the transaction benefits from sufficient liquidity support to withstand high levels of payment holidays in the portfolio. As of the April 2021 payment date, none of the loans were reported to be in a payment holiday.

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 base case PD and LGD of the current pool of loans for the Issuer are 16.7% and 63.1%, respectively.
-- 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 (sf), assuming no change in the PD. If the PD increases by 50%, the rating of the Class A Notes would be expected to remain at AA (sf), assuming no change in the LGD. Furthermore, if both the PD and LGD increase by 50%, the rating of the Class A Notes would be expected to fall to A (sf).

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