DBRS Assigns Provisional Ratings to Together Asset Backed Securitisation 1 Plc

RMBS
September 11, 2017

DBRS Ratings Limited (DBRS) assigned provisional ratings to the notes to be issued by Together Asset Backed Securitisation 1 Plc (Issuer) as follows:

  • Class A notes rated AAA (sf)
  • Class B notes rated AA (sf)
  • Class C notes rated A (high)(sf)
  • Class D notes rated BBB (sf)
  • Class E notes rated BB (high)(sf)

Class Z and Class R notes are not rated.

Together Asset Backed Securitisation 1 Plc (TABS; the issuer) is a public securitisation issuance from Together Financial Services Limited. The portfolio of mortgage loans comprises first and second lien mortgage loans, both owner-occupied and buy-to-let (BTL) backed by residential properties located in the United Kingdom. The loans have been originated by Blemain Finance Limited (BFL), Together Personal Finance Limited (TPFL), Together Commercial Finance Limited (TCFL), each of which belong to the Together Group of companies. A portion of the assets are currently warehoused in Charles Street Asset Backed Securitisation 1 Limited (CABS), which is rated AA (sf) by DBRS.

Each of the originators will be servicers of the loans they have originated. Capita Mortgage Services Limited in place as the standby servicer.

The provisional portfolio consists of loans originated over the last three years and has a weighted-average seasoning of 15.2 months. The aggregate outstanding balance of the provisional portfolio stands at GBP 301.6 million, with a weighted-average current loan-to-value (WACLTV) of 56.9% (57.5% is the weighted-average original loan-to-value (WAOLTV).

The provisional portfolio consists of almost an equal proportion of buy-to-let (BTL) and owner-occupied residential mortgage loans. Across these product types the loans are either first or second charge loans (the latter are approximately 60.4% of the mortgage portfolio – percentages are by outstanding balance insofar as they refer to portfolio proportions) and monthly repayments can be on an interest-only basis (approximately 48.2% of the provisional pool). 72.6% of the provisional portfolio is either for the purpose of debt consolidation or withdrawal of the borrower’s equity in the mortgaged property. About 14.4% of the loans were granted to borrowers with an adverse credit history at the time of origination. Finally, 57.9% of the loans in the portfolio were granted to borrowers who are self-employed. Some of these loans and borrower features overlap for a proportion of loans thus resulting in multiple layers of risk. The key mitigants to such risk layering are the relatively low loan-to-value ratio at origination, the relatively better historical performance of these product types in comparison to other seasoned non-conforming portfolios reviewed by DBRS and the servicing policies and capabilities of the originators.

DBRS expects some of these these recent originations by the originators to perform better than as suggested by the performance history because of tighter affordability tests which consider repayment on a capital plus interest basis for owner-occupied interest-only loans (14.2% of the provisional portfolio). Since the beginning of the year, the affordability tests for BTL loans with less than a five-year teaser period considers higher interest rate stresses.

The credit enhancement to the senior notes is expected to be provided by subordination of the junior notes and an amortising reserve fund which will be 2% of the aggregate closing balance of the Class A to Class E notes. The Class A notes are thus expected to have a credit enhancement of 21%, with Class B notes having 17%, Class C notes 13%, Class D notes 9% and Class E notes 7%. Besides the reserve fund the principal receipts from the mortgage portfolio will be available to support liquidity on the senior fees and interest on the notes. Post the optional redemption date, the available revenue funds after replenishment of the reserve fund to the required level can be used to turbo amortise the notes sequentially.

The mortgage assets pay a variable rate of interest set by the lenders and, in comparison, the interest payable on the notes is linked to three-month GBPLibor. This gives rise to basis risk which is not hedged in the transaction. DBRS has stressed the interest receipts from the mortgage loans in the cash flow analysis to account for potential reduction in interest rates payable on the mortgage loans. DBRS also tested the cash flows from the mortgage loans under a high prepayment scenario of 20%, which simulates further compression of interest receipts from the mortgage loans.

The account bank in the transaction is Elavon Financial Services DAC, UK Branch which is privately rated by DBRS. This counterparty is appropriately rated to mitigate the counterparty risk to the issuer in line with DBRS Legal Criteria for European Stuctured Finance Transactions Methodology.

The ratings on the notes address the timely payment of interest and ultimate payment of principal on or before the legal final maturity date. DBRS based the ratings primarily on the following analytical considerations:

-- The transaction capital structure, form and sufficiency of available credit enhancement and liquidity provisions.
-- The credit quality of the mortgage loan portfolio and the ability of the servicers to perform collection activities. DBRS calculated portfolio default rates (PDRs), loss given default (LGD) and expected loss (EL) outputs on the mortgage loan portfolio.
-- The ability of the transaction to withstand stressed cash flow assumptions and repay the rated notes according to the terms of the transaction documents. The transaction cash flows were modelled using PDRs and LGD outputs of the European RMBS Insight Model. Transaction cash flows were modelled using INTEX DealMaker.
-- The structural mitigants in place to avoid potential payment disruptions caused by operational risk, such as downgrade and replacement language in the transaction documents.
-- The legal structure and presence of legal opinions addressing the assignment of the assets to the Issuer and consistency with DBRS’s “Legal Criteria for European Structured Finance Transactions” methodology.

All figures are in British pounds sterling unless otherwise noted.

The principal methodology applicable to the rating is: “European RMBS Insight Methodology” and “European RMBS Insight: U.K. Addendum”.

DBRS has applied the principal methodology consistently and conducted a review of the transaction in accordance with the principal methodology.

To assess the impact of changing the transaction parameters on the rating, DBRS considered the following stress scenarios, as compared to the parameters used to determine the rating (the “Base Case”). The additional stresses assume a 25% and 50% increase in both the PDRs and LGD assumptions for each series of notes:

The following scenarios constitute the parameters used to determing the Base Case:

-- In respect of the Class A Notes, the PDR and LGD at the AAA (sf) stress scenario of 32.88% and 65.93%, respectively.
-- In respect of the Class B Notes, the PD and LGD at the AA (sf) stress scenario of 29.75% and 61.88%, respectively.
-- In respect of the Class C Notes, the PD and LGD at the A (high) (sf) stress scenario of 26.23% and 56.05%, respectively.
-- In respect of the Class D Notes, the PD and LGD at the BBB (sf) stress scenario of 19.72% and 42.41%, respectively.
-- In respect of the Class E Notes, the PD and LGD at the BB (high) (sf) stress scenario of 14.46% and 33.85%, respectively.

DBRS concludes the following impact on the Class A Notes:
-- 25% increase of the PD, ceteris paribus, would lead to a downgrade to AA (low) (sf).
-- 50% increase of the PD, ceteris paribus, would lead to a downgrade to A (sf).
