DBRS Morningstar Assigns Provisional Ratings to Pavillion Mortgages 2021-1 PLC

DBRS Ratings Limited (DBRS Morningstar) assigned provisional ratings to the following classes of notes to be issued by Pavillion Mortgages 2021-1 PLC (the Issuer):

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

The provisional ratings assigned to the Class A to C notes address the timely payment of interest and the ultimate payment of principal by the legal final maturity date in August 2064. The provisional ratings assigned to the Class D to E 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 in this transaction. The provisional ratings assigned by DBRS Morningstar are based on the final pool data as of 30 November 2021.

The provisional ratings are based on information provided to DBRS Morningstar by the Issuer and its agents as of the date of this press release. These ratings will be finalised upon review of the final version of the transaction documents and of the relevant opinions. If the information therein were substantially different, DBRS Morningstar may assign different final ratings to the notes.

The transaction will be a securitisation of the residential mortgage loans secured by first-lien owner-occupied mortgages originated by Barclays Bank UK PLC (BBUK) in the UK.

BBUK is the servicer of the transaction. CSC Capital Markets UK Limited will be the Backup Servicer Facilitator.

The Issuer is expected to issue five tranches of collateralised mortgage-backed securities, the Class A to Class E notes (the Rated Notes), to finance the purchase of the portfolio. The transaction is structured to initially provide 12.4% of credit enhancement to the Class A notes. This includes subordination of the Class B to E notes.

The liquidity reserve fund (LRF) will be available to cover shortfalls of senior fees and interest on the Class A notes, Class B notes, and the Senior Deferred Consideration payment after the application of revenue and the general reserve fund (GRF). The LRF will be funded from the issuance of the Class R notes on the closing date. The initial balance of the LRF will be 0.5% of the balance of the Class A and Class B notes on the closing date. On each interest payment date (IPD), the target level will be 0.5% of the current Class A and Class B balance subject to the occurrence of a Liquidity Reserve Fund Trigger Event following which the LRF required amount would be equal to 1.0%. The Liquidity Reserve Fund Trigger event means BBUK's long-term issuer default rating is downgraded below "BBB" or its short-term issuer default rating is downgraded below "F2" by Fitch. Any excess amounts above the target will be released to form part of available revenue receipts.

The general reserve fund (GRF) will also provide liquidity and credit support to the Rated Notes subject to the principal deficiency ledger (PDL) Condition being met for those classes. On the closing date and on each IPD following the closing date, the GRF will be equal to 1.75% of the portfolio outstanding balance minus the LRF Required Amount. When Class E is redeemed, the GRF amount is set to zero and released as principal. The GRF will be available to cover shortfalls in senior fees, interest, and any PDL debits on the Class A to Class E notes after the application of revenue funds subject to the PDL Condition being met. When Class E is redeemed, the GRF Required Amount is set to zero and released as principal.

Principal additional amounts can be used if the GRF and LRF were not enough to cover shortfalls in senior fees, Class A interest, and when the relevant PDL balance is less than 10%, Class B to E interest. It cannot be used to cover interest shortfalls for the Senior Deferred Consideration. Any use of principal to cover interest shortfalls will be recorded as a debit in the PDL. The PDL comprises five subledgers that track the principal used to pay interest, as well as realised losses, in a reverse-sequential order that begins with the Class E subledger.

On the IPD in February 2025, the coupon due on the notes will step up and the notes may be optionally called. The notes must be redeemed for an amount sufficient to fully repay them, at par, plus pay any accrued interest.

As of 30 September 2021 , the provisional portfolio consisted of 2,442 loans with an aggregate principal balance of GBP 603.0 million. The portfolio comprises only recent originations with 88.1% of the mortgages originated in 2021, 11.0% in 2020 and remaining 0.9% in 2019. As of the cut-off date, the securitised portfolio had approximately 6.8 months of seasoning.

The weighted-average (WA) original loan-to-value (LTV) ratio of the portfolio is 87.2% whereas the WA indexed current LTV (CLTV) of the portfolio is 86.5% with 99.5% of the mortgage loans having a WA Indexed CLTV of higher than 80%.

The majority of the loans in the portfolio (93.2%) were granted to employed borrowers and the remaining included self-employed borrowers. None of the loans in the pool have prior county court judgements or are currently in arrears, reflecting the good quality of the portfolio.

The entire portfolio pays a fixed rate at closing and all loans in the mortgage portfolio will switch to a tracker linked to the Bank of England rate + 3.49%. No product switches and further advances are allowed in the transaction. The seller has committed to repurchase all mortgages to which BBUK has granted a product switch unless the relevant loan is seen to be in arrears at the end of the month during which such product switch occurred or a further advance is made. In such cases, the loan will not be repurchased. This may create some divergence between the notional of the and actual fixed-rate balance and result in higher prepayment speed. DBRS Morningstar considered this higher risk of prepayments in its cash flow analysis.

The interest on the notes is calculated based on the daily-compounded Sterling Overnight Index Average (Sonia), which gives rise to interest rate risk. DBRS Morningstar has accounted for this fixed-floating interest rate risk in its rating analysis.

DBRS Morningstar based its ratings on a review of the following analytical considerations:
-- The transaction’s capital structure and form and 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 DBRS Morningstar’s “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) with a Stable trend as of the date of this press release.
-- The consistency of the transaction’s legal structure with DBRS Morningstar’s “Legal Criteria for European Structured Finance Transactions” methodology and presence of legal opinions addressing the assignment of the assets to the Issuer.

The Coronavirus Disease (COVID-19) and the resulting isolation measures have caused an immediate economic contraction, leading in some cases to increases in unemployment rates and income reductions for many borrowers. DBRS Morningstar anticipates that delinquencies may continue to increase in the coming months for many RMBS transactions. The ratings are based on additional analysis to expected performance as a result of the global efforts to contain the spread of the coronavirus. For this transaction, DBRS Morningstar incorporated an increase in default probability of self-employed borrowers in its analysis and conducted additional analysis to determine the transaction benefits from sufficient liquidity support in case of high level of payment moratoriums in the portfolio.
