DBRS Morningstar Finalises Provisional Ratings on Pavillion Mortgages 2022-1 PLC

DBRS Ratings Limited (DBRS Morningstar) finalised its provisional ratings on the following classes of notes issued by Pavillion Mortgages 2022-1 PLC (the Issuer):

-- Class A notes at AAA (sf)
-- Class B notes at AAA (sf)
-- Class C notes at AA (high) (sf)
-- Class D notes at A (sf)
-- Class E notes at BB (high) (sf)

The finalised ratings on the Class A and Class B notes address the timely payment of interest and the ultimate repayment of principal by the legal final maturity date. The finalised ratings on the Class C to Class E notes (together with the Class A and Class B notes, the rated notes) address the timely payment of interest once most senior and the ultimate repayment of principal by the legal final maturity date. DBRS Morningstar does not rate the Class R notes also issued in this transaction.

RATING RATIONALE
The Issuer is a bankruptcy-remote special-purpose vehicle incorporated in the UK. The collateralised notes are backed by first-lien owner-occupied residential mortgage loans originated by Barclays Bank UK PLC (BBUK).

A liquidity reserve fund (LRF) provides liquidity support to the Class A and Class B notes and to the senior deferred consideration in the priority of payments. The LRF’s initial balance will be 0.5% of the Class A and Class B notes’ outstanding balance at closing. On each interest payment date (IPD), the target level will be 0.5% of the Class A and Class B notes’ outstanding balance as at the end of the collection period until the Class B notes are redeemed.

A general reserve fund (GRF) provides liquidity and credit support to the rated notes. On the closing date and on each IPD thereafter, the GRF will have a target balance equal to 2.50% of the portfolio’s outstanding balance at closing, minus the LRF required amount.

DBRS Morningstar calculated the credit enhancement to the Class A notes at 15.55%, provided by the subordination of the Class B to Class E notes and the GRF’s initial balance. Credit enhancement to the Class B notes will be 11.30%, provided by the subordination of the Class C to Class E notes and the GRF’s initial balance. Credit enhancement to the Class C notes will be 7.20%, provided by the subordination of the Class D to Class E notes and the GRF’s initial balance. Credit enhancement to the Class D notes will be 3.15%, provided by the subordination of the Class E notes and the GRF’s initial balance. Credit enhancement to the Class E notes will be 2.05%, provided by the GRF’s initial balance.

As of 31 October 2022, the mortgage portfolio consisted of 2,044 loans with an aggregate principal balance of GBP 498.5 million. The majority of the loans in the pool (77% of the initial collateral balance) were originated in the third quarter of 2022 while the rest were granted in the remaining part of 2022. The mortgage loans in the asset portfolio are all secured by a first-ranking mortgage right and almost all were granted to employed borrowers (94.2%).

The portfolio’s weighted-average (WA) original loan-to-value (LTV) ratio and WA indexed current LTV are substantially the same at 89.7% because the properties have not benefitted from material price rises in the short time that has elapsed since origination, and the loans have amortised by less than 0.5% compared with their original balance. This relatively high LTV compared with peer transactions in the UK reflects the pool selection criteria that target high LTV loans in the BBUK book that were granted to first-time buyers.

The final portfolio contains 100% fixed-rate loans with a fixed-rate period. Once their fixed-rate period is over, the loans will switch to a floating rate. As of the final cut-off date, all mortgage loans were performing. The Issuer has entered into a fixed-to-floating swap with BBUK to hedge the interest rate mismatch between the fixed-rate mortgage loans and the compounded Sterling Overnight Index Average (Sonia) rate payable on the notes.

BBUK originated and services the mortgages. CSC Capital Markets UK Limited will be the backup servicer facilitator in the transaction.

DBRS Morningstar based its ratings on a review of the following analytical considerations:
-- The transaction’s capital structure and form and the sufficiency of available credit enhancement.
-- The credit quality of the mortgage portfolio and the ability of the servicer to perform collection and resolution activities. DBRS Morningstar calculated the probability of default (PD), loss given default (LGD), and expected loss outputs on the mortgage portfolio, which DBRS Morningstar used as inputs into the cash flow tool. DBRS Morningstar analysed the mortgage portfolio in accordance with its “European RMBS Insight: UK Addendum”.
-- The ability of the transaction to withstand stressed cash flow assumptions and repay the Class A, Class B, Class C, Class D, and Class E notes according to the terms of the transaction documents. DBRS Morningstar analysed the transaction structure using Intex DealMaker, considering the default rates at which the rated notes did not return all specified cash flows.
-- The structural mitigants in place to avoid potential payment disruptions caused by operational risk, such as a downgrade, and replacement language in the transaction documents.
-- DBRS Morningstar’s sovereign rating on the United Kingdom of Great Britain and Northern Ireland at AA (high), Under Review with Negative Implications, as of the date of this press release.
-- The expected consistency of the transaction’s legal structure with DBRS Morningstar’s “Legal Criteria for European Structured Finance Transactions” methodology and presence of legal opinions that are expected to address the assignment of the assets to the Issuer.
