DBRS Morningstar Confirms Credit Ratings on Towd Point Mortgage Funding 2018-Auburn 12 Plc

DBRS Ratings Limited (DBRS Morningstar) confirmed its credit ratings on the notes issued by Towd Point Mortgage Funding 2018-Auburn 12 Plc (the Issuer):

-- Class A at AAA (sf)
-- Class B at AA (high) (sf)
-- Class C at AA (high) (sf)
-- Class D at AA (low) (sf)
-- Class E at BBB (high) (sf)

The credit rating on the Class A notes addresses the timely payment of interest and the ultimate repayment of principal on or before the legal final maturity date in February 2045. The credit ratings on the Class B, Class C, and Class D notes address the ultimate payment of interest and principal while they are the junior-most class of notes outstanding and the timely payment of interest while they are the senior-most class of notes outstanding. The credit rating on the Class E notes addresses the ultimate payment of interest and principal. DBRS Morningstar’s credit ratings on the Class B, Class C, Class D, and Class E notes do not address interest amounts payable in excess of the transaction net weighted-average coupon cap, which are subordinated items in the revenue priority of payments.

The credit rating 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 September 2023 cut-off date;
-- Portfolio default rate (PD), loss given default (LGD), and expected loss assumptions on the remaining receivables; and
-- Current available credit enhancement to the notes to cover the expected losses at their respective credit rating levels.

The Issuer is a bankruptcy-remote special-purpose vehicle incorporated in the UK. The Issuer used the notes to fund the purchase of UK buy-to-let and owner-occupied residential mortgage loans originated by Capital Home Loans Limited (CHL). CHL acts as the servicer for the portfolio while Homeloan Management Limited acts as the backup servicer. The First Optional Redemption Date (FORD) was on the February 2023 payment date.

PORTFOLIO PERFORMANCE
As of September 2023 cut-off, loans two to three months in arrears represented 0.7% of the outstanding portfolio balance and the 90+-day delinquency ratio was 3.4%. As of the September 2023 cut-off date, the cumulative default ratio was 4.9%.

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 to 4.6% and 4.3%, respectively.

CREDIT ENHANCEMENT
As of the August 2023 payment date, the credit enhancement available to the Class A, Class B, Class C, Class D, and Class E notes was 35.6%, 21.1%, 14.9%, 9.4%, and 4.1%, respectively, compared with 28.6%, 17.5%, 12.7%, 8.5%, and 4.5%, 12 months prior, respectively. Credit enhancement in each case is provided by the subordination of junior classes.

Following the FORD, the transaction benefits from a liquidity reserve fund (LRF) of GBP 3.2 million, which covers the senior expenses and the interest on the Class A notes. The LRF has a required balance of 1.7% of the Class A notes and is currently funded to its target level.

Additionally, the transaction benefits from an Excess Cashflow Reserve Fund currently funded at GBP 2.9 million, which covers the interest on the Class B, Class C, Class D, and Class E notes. The reserve was funded on and following the FORD, using excess amounts on the SDC Ledger after funding the LRF and any excess liquidity amounts.

HSBC Bank plc acts as the account bank for the transaction. Based on DBRS Morningstar’s private rating on HSBC Bank plc, 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 credit rating assigned to the Class A notes, as described in DBRS Morningstar's "Legal Criteria for European Structured Finance Transactions" methodology.

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

DBRS Morningstar’s credit rating on the notes also addresses 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 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.

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

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 4.6% and 4.3%, 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. For example, if the LGD increases by 50%, the credit rating on the Class A notes would be expected to remain at AAA (sf), assuming no change in the PD. If the PD increases by 50%, the credit rating on the Class A notes would be expected to remain at AAA (sf), assuming no change in the LGD. Furthermore, if both the PD and LGD increase by 50%, the credit rating on the Class A notes would be expected to remain at AAA (sf).

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