DBRS Morningstar Upgrades and Confirms Ratings on Trinidad Mortgage Securities 2018-1 plc
RMBSDBRS Ratings Limited (DBRS Morningstar) took the following rating actions on the notes issued by Trinidad Mortgage Securities 2018-1 plc (the Issuer):
-- Class A notes confirmed at AAA (sf)
-- Class B notes upgraded to AA (high) (sf) from AA (sf)
-- Class C notes upgraded to AA (sf) from A (sf)
-- Class D notes upgraded to A (high) (sf) from BBB (sf)
-- Class E notes upgraded to BBB (high) (sf) from BB (sf)
-- Class F notes upgraded to BB (sf) from B (high) (sf)
The rating of the Class A notes addresses the timely payment of interest and the ultimate repayment of principal by the Legal Final Maturity Date in January 2059. The ratings of the Class B and Class C notes address the ultimate payment of interest and principal on or before the legal final maturity date while junior and the timely payment of interest while the senior-most class outstanding. The ratings of the Class D, Class E, and Class F notes address the ultimate payment of interest and repayment of principal by the Legal Final Maturity Date.
The confirmation and upgrades 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 July 2021 payment date;
-- 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; and
-- Current economic environment and an assessment of sustainable performance, as a result of the Coronavirus Disease (COVID-19) pandemic.
The Issuer is a securitisation of first- and second-ranking mortgages secured by residential and commercial properties located in the United Kingdom. The asset portfolio comprises three distinct subsets originated by multiple lenders and serviced by Mars Capital Finance Limited.
The Magellan portfolio was originated by Magellan Homeloans Limited and Mars Capital Finance Limited and consists of recently originated credit repair mortgages and complex-prime and near-prime mortgages. The Thrones 2013 portfolio consists of first- and second-ranking nonconforming residential mortgages originated by Heritable Bank between 2004 and 2008. The Camael portfolio was originated by Cyprus Popular Bank Co Ltd and consists of first- and second-ranking residential and commercial mortgages, both buy-to-let and owner-occupied.
PORTFOLIO PERFORMANCE
As of the July 2021 payment date, 30- to 90-day arrears for the total portfolio were 5.5%, down from 7.1% in July 2020. The 90+-day delinquency ratio was 6.9%, down from 10.7% in July 2020. 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 updated its base case PD and LGD assumptions to 22.6% and 13.2%, respectively, including coronavirus-related adjustments.
CREDIT ENHANCEMENT
As of the July 2021 payment date, credit enhancement to the Class A, Class B, Class C, Class D, Class E, and Class F notes was 65.1%, 47.8%, 34.2%, 24.3%, 18.1%, and 15.9%, respectively, up from 25.7%, 18.7%, 13.2%, 9.2%, 6.7%, and 5.8% at the initial rating, respectively. Credit enhancement consists of subordination of the junior notes and the general reserve fund (GRF). The increase in credit enhancement prompted the rating upgrades on the notes.
The GRF is nonamortising and is available to cover senior fees, interest shortfall on the senior-most outstanding class of notes, as well as the principal deficiency ledgers on the rated notes. It is currently funded to its target level of GBP 11.2 million.
If the balance of the GRF falls to 2% of the outstanding Class A to H notes, a liquidity reserve fund (LRF) will be funded to 4% of the outstanding Class A notes and will be available to cover senior fees and Class A interest only. The LRF balance is currently zero.
Citibank N.A./London Branch acts as the account bank for the transaction. Based on DBRS Morningstar’s private rating of Citibank N.A./London Branch, 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.
NatWest Markets Plc acts as the interest rate cap provider for the transaction. DBRS Morningstar's public Long Term Critical Obligations Rating of NatWest Markets Plc at ‘A’ is consistent with the First Rating Threshold as described in DBRS Morningstar's "Derivative 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 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 structured finance 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 increased the expected default rate for certain borrower characteristics and loans backed by commercial properties, applied an additional haircut to its expected recovery rates for commercial properties, and conducted additional sensitivity analysis to determine that the transaction benefits from sufficient liquidity support to withstand potential high levels of payment holidays in the portfolio.
The DBRS Morningstar Sovereign group releases baseline macroeconomic scenarios for rated sovereigns. These scenarios were last updated on 8 September 2021.

For more information regarding structured finance rating methodologies and Coronavirus Disease (COVID-19), please see the following DBRS Morningstar press release: https://www.dbrsmorningstar.com/research/358308.
The rating of the Class D notes at A (high) (sf) materially deviates from the higher rating implied by the quantitative model. DBRS Morningstar considers a material deviation to be a rating differential of three or more notches between the assigned rating and the rating implied by a quantitative model that is a substantial component of a rating methodology. In this case, the rating addresses the ultimate payment of interest and principal by the final maturity date as defined in the transaction legal documents. DBRS Morningstar typically expects bonds rated in the AA (sf) category to be able to pay interest on a timely basis at the time they are the most senior bond outstanding.

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 22.6% and 13.2%, 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 remain at AAA (sf).
