DBRS Morningstar Assigns Ratings to Charles Street Conduit Asset Backed Securitisation 2 Limited

RMBS
March 08, 2022

DBRS Ratings Limited (DBRS Morningstar) assigned ratings to the notes issued by Charles Street Conduit Asset Backed Securitisation 2 Limited (the Issuer) as follows:

-- Class A Notes at AA (sf)
-- Class B Notes at BBB (high) (sf)
-- Class C Notes at BB (high) (sf)

The ratings on the Class A, Class B, and Class C Notes (collectively, the Notes) address the timely payment of interest and the ultimate payment of principal on or before the legal final maturity date in December 2067.

The transaction consists of Notes issued through the Note Issuance Facility Agreement and the Subordinated Notes issued through the Subordinated Note Subscription Agreement. The Notes and the Subordinated Notes are collateralised by UK residential mortgages originated and serviced by various subsidiaries of Together Financial Services Limited (Together), including Blemain Finance Limited, Together Commercial Finance Limited, Harpmanor Limited, and Together Personal Finance Limited. Each originator will be the servicer of the loans it has originated. BCMGlobal Mortgage Services Limited acts as the standby servicer.

The Class A Notes are tranched into pro rata pari passu Class A1 and Class A2 Notes. The Class A1, Class B, and Class C Notes are issued and listed with The International Stock Exchange and held at Euroclear. The Class A2 Notes are in the form of variable-funding notes. Prior to the initial maturity date, the Issuer may issue and list additional Class A1, Class B, and Class C Notes. The Class A1 Notes are fungible with the Class A2 Notes. The commitment amount for the Class A Notes is GBP 1.15 billion. The total subscription amounts for the Class B and C Notes are GBP 67.6 million and GBP 33.8 million, respectively. The transaction includes a 48-month revolving period, during which the Issuer may purchase new loans subject to satisfying the portfolio covenants.

The subordination to the Notes can increase with changes in the advance rate or decrease to a floor determined by the respective advance rate caps. This is based on the changing credit risk profile of the mortgage portfolio linked to the portfolio loan-to-value ratio, among other credit metrics, as the Issuer purchases new mortgage loans into the portfolio. Minimum credit enhancement to the Class A, Class B, and Class C Notes is 15.0%, 10.0%, and 7.5%, respectively.

The transaction benefits from a Co-mingling Reserve Fund with a target balance equal to 1.5% of the outstanding Class A, Class B, and Class C Notes’ balance. Prior to the initial maturity date, the reserve fund is replenished through the principal receipts. The reserve covers any shortfalls in senior fees and interest on the Class A Notes. After the initial maturity date, the excess cash over the target amount following the amortisation of the Notes will be released to the interest waterfalls as available funds and the Issuer may use them to repay principal on the Notes.

Lloyds Bank plc (Lloyds) acts as the account bank for the transaction. Based on the account bank reference rating of AA on Lloyds (one notch below the DBRS Morningstar public Long Term Critical Obligations Rating of AA (high)), 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.

Natixis, S.A. (Natixis) acts as the swap counterparty for the transaction. DBRS Morningstar's private rating on Natixis is above the First Rating Threshold as described in DBRS Morningstar's "Derivative 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 servicers to perform collection and resolution activities. DBRS Morningstar calculated the probability of default (PD), loss given default (LGD), and expected loss (EL) outputs on the mortgage portfolio, which DBRS Morningstar then used as inputs into the cash flow engine. 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, and Class C 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 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 the 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.
