Morningstar DBRS Confirms Credit Ratings on Canterbury Finance 5 PLC

DBRS Ratings Limited (Morningstar DBRS) confirmed the AAA (sf) credit ratings on the Class A1 and Class A2 notes issued by Canterbury Finance 5 PLC (the Issuer).

The credit ratings on the Class A1 and Class A2 notes address the timely payment of interest and ultimate payment of principal on or before the legal final maturity date in May 2059.

The credit rating actions follow an annual review of the transaction and are based on the following analytical considerations:

-- Portfolio performance, in terms of delinquencies, defaults and losses.
-- Portfolio default rate (PD), loss given default (LGD) and expected loss assumptions on the remaining receivables.
-- Current available credit enhancement to the notes to cover the expected losses at the AAA (sf) credit rating level.

The transaction is a securitisation of buy-to-let residential mortgage loans originated and serviced by OneSavings Bank plc.
PORTFOLIO PERFORMANCE
As of June 2024, loans two to three months in arrears represented 0.5% of the outstanding portfolio balance, loans more than three months in arrears represented 1.1%, and the cumulative default ratio was 0.0%.

PORTFOLIO ASSUMPTIONS AND KEY DRIVERS
Morningstar DBRS conducted a loan-by-loan analysis of the remaining pool of receivables and has updated its base case PD and LGD assumptions at the B (sf) rating level to 5.5% and 18.0% respectively.

CREDIT ENHANCEMENT
As of the June 2024 payment date, credit enhancement to the Class A1 and Class A2 notes was 24.6%, up from 14.5% at the Morningstar DBRS initial rating. Credit enhancement is provided by subordination of junior classes of notes.

The transaction additionally benefits from a general reserve fund, currently at its target level of GBP 7.9 million and available to cover senior fees and interest on the Class A1 and Class A2 notes.

Elavon Financial Services DAC, U.K. Branch acts as the account bank for the transaction. Based on the Morningstar DBRS private credit rating of Elavon Financial Services DAC, U.K. Branch, the downgrade provisions outlined in the transaction documents, and other mitigating factors inherent in the transaction structure, Morningstar DBRS considers the risk arising from the exposure to the account bank to be consistent with the credit ratings assigned to the Class A1 and Class A2 notes, as described in Morningstar DBRS' "Legal Criteria for European Structured Finance Transactions" methodology.

Banco Santander SA acts as the swap counterparty for the transaction. Morningstar DBRS' public Long Term Critical Obligations Rating of Banco Santander SA at AA (low) is above the First Rating Threshold as described in Morningstar DBRS' "Derivative Criteria for European Structured Finance Transactions" methodology.

Morningstar DBRS' credit ratings on the applicable classes address the credit risk associated with the identified financial obligations in accordance with the relevant transaction documents.

Sensitivity Analysis: To assess the impact of changing the transaction parameters on the credit rating, Morningstar DBRS considered the following stress scenarios as compared with the parameters used to determine the credit rating (the base case):

-- Morningstar 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 at the B (sf) credit rating level are 5.5% and 18.0%, respectively.
-- The risk sensitivity overview below illustrates the credit ratings expected if the PD and LGD increase by a certain percentage over the base case assumption.

Class A1 Risk Sensitivity:
-- 25% increase in LGD, expected credit rating of AAA (sf)
-- 50% increase in LGD, expected credit rating of AAA (sf)
-- 25% increase in PD, expected credit rating of AAA (sf)
