DBRS Morningstar Confirms Ratings on Harbour No. 1 plc

DBRS Ratings Limited (DBRS Morningstar) confirmed its credit ratings on the notes issued by Harbour No. 1 plc (the Issuer) as follows:

-- Class A1 Notes at AAA (sf)
-- Class A2 Notes at AAA (sf)
-- Class B Notes at AA (high) (sf)
-- Class C Notes at AA (sf)
-- Class D Notes at A (high) (sf)
-- Class E Notes at A (low) (sf)
-- Class F Notes at BBB (low) (sf)
-- Class G Notes at BB (low) (sf)
-- Class X Notes at AA (high) (sf)

The credit ratings on the Class A1 and Class A2 Notes address the timely payment of interest and ultimate repayment of principal on or before the legal final maturity date. The credit rating on the Class B Notes addresses the ultimate payment of interest and principal on or before the legal final maturity date while junior, and timely payment of interest while the senior-most class outstanding. The credit ratings on the Class C, Class D, Class E, Class F, Class G, and Class X Notes address the ultimate payment of interest and principal on or before the legal final maturity date.

The confirmations follow an annual review of the transaction and are based on the following analytical considerations:
-- Portfolio performance, in terms of delinquencies, defaults and losses, as of the October 2023 payment date.
-- Probability of default (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 their respective rating levels.

The transaction is a securitisation of owner-occupied and buy-to-let residential mortgages originated by several defunct originators. The portfolio was assembled by buying three different portfolios: the Wall portfolio, the MAQ portfolio, and the Morag portfolio. Each portfolio is serviced by a different servicer: the Wall portfolio is serviced by Mars Capital Finance Limited, the MAQ portfolio is serviced by Pepper (UK) Limited, and the Morag portfolio is serviced by Topaz Finance Limited.

PORTFOLIO PERFORMANCE
As of 30 September 2023, loans two to three months in arrears represented 4.4% of the outstanding portfolio balance, up from 3.3% a year prior. Loans more than three months in arrears represented 27.1% of the outstanding portfolio, up from 20.0% a year prior. Cumulative principal losses were 0.3%.

PORTFOLIO ASSUMPTIONS AND KEY DRIVERS
DBRS Morningstar conducted a loan-by-loan analysis of the remaining pool of receivables and updated its base case PD and LGD assumptions at the B (sf) rating level to 32.6% and 8.1%, respectively.

CREDIT ENHANCEMENT
Credit enhancement to the Class A to Class G Notes is provided by subordination of the junior notes and the general reserve fund (GRF). As of the October 2023 payment date, credit enhancement had increased from the DBRS Morningstar Initial Rating as follows:
-- Class A1 Notes: 61.9%, up from 49.3%;
-- Class A2 Notes: 43.7%, up from 34.5%;
-- Class B Notes: 35.1%, up from 27.5%;
-- Class C Notes: 31.4%, up from 24.5%;
-- Class D Notes: 23.7%, up from 18.3%;
-- Class E Notes: 18.2%, up from 13.8%;
-- Class F Notes: 13.8%, up from 10.3%; and
-- Class G Notes: 10.1%, up from 7.3%.

The transaction benefits from a liquidity reserve fund (LRF) of GBP 1.7 million, equal to 0.5% of the initial Class A1 and Class A2 Notes balance. The LRF covers senior fees and interest on the Class A1 and Class A2 Notes.

The GRF is nonamortising and covers senior fees, interest on the Class A to Class G Notes, and principal losses via the principal deficiency ledgers (PDL) on the Class A to Class G Notes (subject to a PDL condition of 10% for each class of notes, unless they are the most senior outstanding). The target balance of the GRF is 1.25% of the initial portfolio balance. The GRF is currently funded below its target to GBP 4.7 million.

Barclays Bank PLC acts as the account bank for the transaction. Based on the account bank reference rating of Barclays Bank PLC at A (high), which is one notch below the DBRS Morningstar public Long-Term Critical Obligations Rating of AA (low); 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 ratings assigned to the Class A1 and Class A2 Notes, as described in DBRS Morningstar's "Legal Criteria for European Structured Finance Transactions" methodology.

DBRS Morningstar’s credit ratings on the notes address the credit risk associated with the identified financial obligations in accordance with the relevant transaction documents.

DBRS Morningstar’s credit ratings on the notes also address the credit risk associated with the increased rate of interest applicable to the notes if the notes are not redeemed on the Optional Redemption Date (as defined in and) in accordance with the applicable transaction documents.

DBRS Morningstar’s credit ratings do 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.

ENVIRONMENTAL, SOCIAL, GOVERNANCE CONSIDERATIONS
There were no Environmental/Social/Governance factors that had a significant or relevant effect on the credit analysis.

A description of how DBRS Morningstar considers ESG factors within the DBRS Morningstar analytical framework can be found in the DBRS Morningstar Criteria: Approach to Environmental, Social, and Governance Risk Factors in Credit Ratings at https://www.dbrsmorningstar.com/research/416784/dbrs-morningstar-criteria-approach-to-environmental-social-and-governance-risk-factors-in-credit-ratings.

DBRS Morningstar analysed the transaction structure in Intex DealMaker.

Notes:
All figures are in British pound sterling unless otherwise noted.

The principal methodology applicable to the credit ratings is the “Master European Structured Finance Surveillance Methodology” (22 October 2023): https://www.dbrsmorningstar.com/research/422281/master-european-structured-finance-surveillance-methodology.

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

The rating on the Class D Notes at A (high) (sf) materially deviates from the rating implied by the predictive model. DBRS Morningstar typically expects there to be a substantial likelihood that a reasonable investor or other user of the credit rating would consider a three-notch or more deviation from the credit rating stress implied by the predictive model to be a significant factor in evaluating the credit rating. The rating on the Class D Notes addresses the ultimate payment of interest and principal by the legal final maturity date. For ratings in the AA (sf) range, DBRS Morningstar typically expects interest to be paid on a timely basis when the relevant class of notes becomes the most senior outstanding.

DBRS Morningstar 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 credit rating action.

DBRS Morningstar considers the data and information available to it for the purposes of providing these credit ratings to be of satisfactory quality.

DBRS Morningstar does not audit or independently verify the data or information it receives in connection with the credit rating process.

The last credit rating action on this transaction took place on 19 December 2022, when DBRS Morningstar confirmed its ratings of the Class A1 and Class A2 Notes at AAA (sf), and upgraded its ratings of the Class B, Class C, Class D, Class E, Class F, Class G, and Class X Notes to AA (high) (sf), AA (sf), A (high) (sf), A (low) (sf), BBB (low) (sf), BB (low) (sf) and AA (high) (sf), respectively, following the publication of DBRS Morningstar’s updated “European RMBS Insight: UK Addendum” methodology. DBRS Morningstar also removed its Under Review with Positive Implications status on the Class B to Class X Notes.

Sensitivity Analysis: To assess the impact of changing the transaction parameters on the credit rating, DBRS Morningstar considered the following stress scenarios as compared with the parameters used to determine the credit 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 at the B (sf) credit rating level are 32.6% and 8.1%, respectively.
