DBRS Morningstar Finalises Provisional Ratings on Gemgarto 2021-1 plc

DBRS Ratings Limited (DBRS Morningstar) finalised the provisional ratings on the following classes of notes issued by Gemgarto 2021-1 plc (GMG21-1 or the Issuer):

-- Class A Notes at AAA (sf)
-- Class B Notes at AA (sf)
-- Class C Notes at A (sf)
-- Class D Notes at A (low) (sf)
-- Class X Notes at BB (high) (sf)

The final ratings assigned to the Class B, Class C, Class D, and Class X notes differ from the provisional ratings of AA (low) (sf), A (low) (sf), BBB (high) (sf), and BB (low) (sf), respectively, because of the tighter spreads and step-up margins on Class A through Class X and a lower initial swap rate in the final structure.

The rating on the Class A Notes addresses the timely payment of interest and the ultimate repayment of principal on or before the Final Maturity Date. The ratings on the Class B, Class C, and Class D notes address the timely payment of interest once most senior and the ultimate repayment of principal on or before the Final Maturity Date. The rating on the Class X Notes addresses the ultimate payment of interest and repayment of principal by the Final Maturity Date. DBRS Morningstar does not rate the Class E or Class Z notes.

GMG21-1 is a securitisation collateralised by a portfolio of owner-occupied residential mortgage loans granted by Kensington Mortgage Company Limited (KMC) in England, Wales, and Scotland.

The Issuer issued five tranches of collateralised mortgage-backed securities (Class A to Class E notes) to finance the purchase of the initial portfolio. Additionally, GMG21-1 issued two classes of noncollateralised notes, the Class X and Class Z notes, whose proceeds funded the general reserve fund (GRF) and covered initial costs and expenses. The Class X Notes will primarily amortise using revenue funds; however, if the excess spread is insufficient to fully redeem the Class X Notes, principal funds will be used to amortise the Class X Notes in priority to the Class E Notes.

The transaction structure includes a four-year replenishment period. During this time, principal receipts can be applied to purchase further mortgage loans, subject to additional loan criteria, once there are sufficient principal funds to amortise the Class A Notes to the target notional amount.

The GRF, funded at closing with GBP 9.4 million, is available to provide liquidity and credit support to the Class A to Class D notes. From the first payment date onwards, the required GRF balance will be 2.0% of the balance of the Class A to Class E notes. If the GRF balance falls below 1.5% of the Class A to Class E notes’ balance, principal available funds will be used to fund the liquidity reserve fund (LRF), which will be available to cover interest shortfalls on the Class A and Class B notes, as well as senior items from the pre-enforcement revenue priority of payment. The availability of the LRF for paying interest on the Class B Notes is subject to a 10% principal deficiency ledger condition.

As of 31 January 2021, the portfolio consisted of 2,798 loans with an aggregate principal balance of GBP 470.7 million. Some of these loans (29.7%) in the initial portfolio were previously securitised under the Finsbury Square 2018-1 transaction. The mortgage loans in the asset portfolio are all classified as owner-occupied and are secured by a first-ranking mortgage right.

The portfolio contains 4.5% interest-only and part-and-part loans, and 42.8% of the loans were granted to self-employed borrowers. Furthermore, loans with prior County Court Judgements (CCJs) comprise 11.5% of the mortgage pool and 13.4% of the loans were granted under the Help-to-Buy (HTB) scheme. All of these loans have at least three years of clean credit history in terms of CCJs, defaults, Individual Voluntary Agreements, and bankruptcies. As of the cut-off date, loans in arrears between one and three months represented 2.2% of the outstanding principal balance of the portfolio; no loans were three months or more in arrears.

The majority of the initial portfolio (88.4%) are loans that pay a fixed rate of interest for a teaser period of between two and five years before they will change to a floating rate. After having switched, the majority of these loans will be linked to three-month Libor with a small portion of loans switching to the Kensington Standard Rate (KSR). The remaining 11.6% of the portfolio balance are floating-rate loans that have already switched from their initial fixed-rate period in the past and are indexed to three-month Libor. The notes are all floating rate linked to Sterling Overnight Index Average (Sonia). Interest rate risk is expected to be hedged through an interest rate swap.

The Issuer has entered into a fixed-floating swap with BNP Paribas, London Branch (BNP London) to mitigate the fixed-interest rate risk from the mortgage loans and Sonia payable on the notes. Based on the DBRS Morningstar private rating of BNP London, the downgrade provisions outlined in the documents, and the transaction structural mitigants, DBRS Morningstar considers the risk arising from the exposure to BNP London to be consistent with the ratings assigned to the rated notes as described in DBRS Morningstar's “Derivative Criteria for European Structured Finance Transactions” methodology.

Citibank, N.A., London Branch (Citibank London) holds the Issuer’s transaction account, the GRF, the LRF, and the swap collateral account. Based on the DBRS Morningstar private rating of Citibank London, the downgrade provisions outlined in the documents, and the transaction structural mitigants, DBRS Morningstar considers the risk arising from the exposure to Citibank London to be consistent with the ratings assigned to the rated notes as described in DBRS Morningstar's “Legal Criteria for European Structured Finance Transactions” methodology.

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 probability of default (PD), loss given default (LGD), and expected loss outputs on the mortgage portfolio, which are used as inputs into the cash flow tool. The mortgage portfolio was analysed 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 X notes according to the terms of the transaction documents. The transaction structure was analysed 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 report.
-- 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 economic contraction, leading to sharp 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 structured finance transactions, some meaningfully. The ratings are based on additional analysis and, where appropriate, additional stresses to expected performance as a result of the global efforts to contain the spread of the coronavirus.

On 16 April 2020, the DBRS Morningstar Sovereign group released a set of macroeconomic scenarios for the 2020-22 period in select economies. These scenarios were last updated on 28 January 2021. For details, see the following commentaries: https://www.dbrsmorningstar.com/research/372842/global-macroeconomic-scenarios-january-2021-update and https://www.dbrsmorningstar.com/research/359903/global-macroeconomic-scenarios-application-to-credit-ratings. The DBRS Morningstar analysis considered impacts consistent with the moderate scenario in the referenced reports.

On 5 May 2020, DBRS Morningstar published a commentary outlining how the coronavirus crisis is likely to affect the ratings of DBRS Morningstar-rated RMBS transactions in Europe.
