DBRS Upgrades Rating on Thetis Finance No. 1

May 15, 2019

DBRS Ratings Limited (DBRS) upgraded the Class A Notes issued by Thetis Finance No. 1 (the Issuer) to A (high) (sf) from A (sf).

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

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.
--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 A (high) (sf) rating level.

The Issuer 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.

As of February 2019, loans that were two- to three-months in arrears represented 0.3% of the outstanding portfolio balance, stable since February 2018, and the cumulative default ratio was 3.3%.

DBRS conducted a loan-by-loan analysis of the remaining pool of receivables and has updated its base case PD and LGD assumptions to 16.7% and 61.2%, respectively.

As of the March 2019 payment date, credit enhancement to the Class A Notes was 29.0%, up from 21.9% at the DBRS initial rating. Credit enhancement is provided by subordination of part of the Class B Notes and has increased following termination of the revolving period.

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 4.3 million (1.25% of Class A outstanding principal) and is available to cover senior fees and Class A interest.

Crédit Agricole Corporate & Investment Bank S.A. (CA CIB) acts as the account bank for the transaction. Based on the DBRS private rating of CA CIB, the downgrade provisions outlined in the transaction documents, and other mitigating factors inherent in the transaction structure, DBRS 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's "Legal Criteria for European Structured Finance Transactions" methodology.

The transaction structure was analysed in Intex DealMaker.

All figures are in euros unless otherwise noted.

The principal methodology applicable to the rating is the “Master European Structured Finance Surveillance Methodology”.

DBRS has applied the principal methodology consistently and conducted a review of the transaction in accordance with the principal methodology.

A review of the transaction legal documents was not conducted as the legal documents have remained unchanged since the most recent rating action.

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

-- DBRS 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 61.2%, 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 fall to BBB (high) (sf), assuming no change in the PD. If the PD increases by 50%, the rating of the Class A Notes would be expected to fall to BBB (high) (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 BB (sf).

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