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

DBRS Ratings Limited (DBRS Morningstar) took the following rating actions on the bonds issued by Towd Point Mortgage Funding 2018-Auburn 12 Plc (the Issuer):

-- Class A confirmed at AAA (sf)
-- Class B upgraded to AA (sf) from AA (low) (sf)
-- Class C confirmed at A (sf)
-- Class D confirmed at BBB (sf)
-- Class E upgraded to BB (sf) from BB (low) (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 in February 2045. The ratings on the Class B, Class C, Class D, and Class E notes address the ultimate payment of interest and principal on or before the legal final maturity date.

The 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 their respective rating levels.
-- Current economic environment and an assessment of sustainable performance, as a result of the Coronavirus Disease (COVID-19) pandemic.

The Issuer is a bankruptcy-remote special-purpose vehicle incorporated in the United Kingdom (UK). The issued notes have been used to fund the purchase of UK buy-to-let and owner-occupied residential mortgage loans originated by Capital Home Loans Limited (CHL). The portfolio is serviced by CHL, with Homeloan Management Limited in place as the backup servicer.

PORTFOLIO PERFORMANCE
As of May 2020, loans two to three months in arrears represented 0.2% of the outstanding portfolio balance, and the 90+ delinquency ratio was 0.9%. As of May 2020, the cumulative default ratio was 1.5% and the cumulative loss ratio was 0.1%.

PORTFOLIO ASSUMPTIONS AND KEY DRIVERS
DBRS Morningstar conducted a loan-by-loan analysis of the remaining pool of receivables and has updated its base case PD and LGD assumptions to 4.0% and 19.9%, respectively.

CREDIT ENHANCEMENT
As of the May 2020 payment date, the credit enhancement available to the Class A, Class B, Class C, Class D, and Class E notes were 20.6%, 12.6%, 9.2%, 6.1%, and 3.2%, respectively, up from 18.2%, 11.1%, 8.0%, 5.3%, and 2.7%, 12 months prior, respectively. Credit enhancement in each case is provided by subordination of junior classes.

HSBC Bank plc acts as the account bank for the transaction. Based on the DBRS Morningstar private rating of 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 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 arise in the coming months for many RMBS 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 increased the expected default rate for self-employed borrowers, assessed a potential reduction in portfolio prepayment rates, incorporated a moderate reduction in residential property values and considered reported payment holidays in its cash flow analysis.

The DBRS Morningstar Sovereign group released on 16 April 2020 a set of macroeconomic scenarios for the 2020-22 period in select economies. These scenarios were last updated on 22 July 2020.

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 4.0% and 19.9%, 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 AAA (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 AAA (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 AA (low) (sf).

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