DBRS Ratings Limited (DBRS Morningstar) confirmed its ratings on the notes issued by Charles Street Conduit Asset Backed Securitisation 2 Limited (the Issuer) as follows.

Class A1/Class A2 Notes (collectively, the 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 rated notes) address the timely payment of interest and the ultimate repayment of principal on or before the legal final maturity date.

The confirmations 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 January 2023 payment date.

Probability of default (PD), loss given default (LGD), and expected loss assumptions on the remaining receivables.

Current available credit enhancement to the rated notes to cover the expected losses at their respective rating levels.

No early termination events have occurred.

The transaction is a revolving warehouse securitisation of UK first and second lien buy-to-let and owner-occupied mortgages backed by residential properties located in the United Kingdom. The mortgages were originated 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 of the originators is the servicer of the loans they have originated. BCM Global Mortgage Services Limited acts as the standby servicer.

Until the initial maturity date falling in March 2026 (48 months from the issuance date), the Issuer may use the principal receipts or available/undrawn facility commitment amounts to purchase new loan receivables. Each purchased loan needs to meet the eligibility criteria and adhere to the portfolio covenants.

PORTFOLIO PERFORMANCE

As of the January 2023 payment date, loans two to three months in arrears represented 0.9% of the outstanding portfolio balance, and loans more than three months in arrears represented 0.4% of the outstanding portfolio balance. The cumulative default ratio was 0.6%.

PORTFOLIO ASSUMPTIONS AND KEY DRIVERS

DBRS Morningstar conducted a loan-level analysis of the receivables based on the worst-case portfolio composition given the transaction revolving period. DBRS Morningstar assumes a base case PD and LGD at the B (sf) rating level of 10.0% and 11.4%, respectively. The assumptions continue to be based on the worst-case portfolio composition outlined in the portfolio covenants.

CREDIT ENHANCEMENT

Subordination to the notes increases with changes in the advance rate or decreases to a floor determined by the Advance Rate Caps. The Class A, Class B, and Class C Notes benefit from a minimum subordination of 15.0%, 10.0% and 7.5%, respectively.

A co-mingling reserve is in place to cover shortfalls in senior fees, swap payments, and Class A interest. The target amount is 1.5% of the outstanding balance of the notes and is replenished through principal collections prior to the initial maturity date. The reserve is currently funded to its target balance of GBP 11.0 million.

Lloyds Bank plc acts as the account bank for the transaction. Based on the account bank reference rating of Lloyds Bank plc at AA - being 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. acts as the swap counterparty for the transaction. DBRS Morningstar's private rating of Natixis S.A. is consistent with the First Rating Threshold as described in DBRS Morningstar's 'Derivative Criteria for European Structured Finance Transactions' methodology.

Notes:

All figures are in British pound sterling unless otherwise noted.

The principal methodology applicable to the ratings is the 'Master European Structured Finance Surveillance Methodology' (7 February 2023): https://www.dbrsmorningstar.com/research/409485/master-european-structured-finance-surveillance-methodology>.

Other methodologies referenced in this transaction are listed at the end of this press release. These may be found at: https://www.dbrsmorningstar.com/about/methodologies>.

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

An asset and a cash flow analysis were both conducted. Due to the inclusion of a revolving period in the transaction, the analysis considers potential portfolio migration based on the replenishment criteria set forth in the transaction legal documents.

A review of the transaction legal documents was conducted following amendments to the hedging agreement in June 2022, which involved the realignment of the swap notional with the outstanding balance of the fixed-rate mortgages. The transaction legal documents were also reviewed in relation to an amendment to the weighted-average interest rate covenant in November 2022, in order to maintain a minimum margin of 3.5% post-swap.

Sensitivity Analysis: To assess the impact of changing the transaction parameters on the ratings, DBRS Morningstar considered the following stress scenarios as compared with the parameters used to determine the ratings (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 at the B (sf) rating level are 10.0% and 11.4%, 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 fall to AA (low) (sf), assuming no change in the PD. If the PD increases by 50%, the rating of the Class A Notes would be expected to fall to AA (low) (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 fall to A (low) (sf).

Class A Notes Risk Sensitivity:

25% increase in LGD, expected rating of AA (sf)

50% increase in LGD, expected rating of AA (low) (sf)

25% increase in PD, expected rating of AA (sf)

50% increase in PD, expected rating of AA (low) (sf)

25% increase in PD and 50% increase in LGD, expected rating of A (high) (sf)

50% increase in PD and 25% increase in LGD, expected rating of A (high) (sf)

50% increase in PD and 50% increase in LGD, expected rating of A (low) (sf)

Class B Notes Risk Sensitivity:

25% increase in LGD, expected rating of BBB (high) (sf)

50% increase in LGD, expected rating of BBB (high) (sf)

25% increase in PD, expected rating of BBB (high) (sf)
