DBRS Morningstar Finalises Provisional Ratings on Bastion 2022-1 NHG B.V.

RMBS

November 29, 2022

DBRS Ratings GmbH (DBRS Morningstar) finalised its provisional ratings of AAA (sf) on both the Class A1 and Class A2 notes issued by Bastion 2022-1 NHG B.V. (the Issuer).

DBRS Morningstar does not rate the Class B or Class C notes also issued in this transaction.

The finalised rating on the Class A1 notes addresses the timely payment of interest and the ultimate repayment of principal by the legal final maturity date in May 2060. The finalised rating on the Class A2 notes addresses the ultimate payment of principal by the legal final maturity date.

The Issuer issued three tranches of mortgage-backed securities (namely, Class A1, Class A2, and Class B notes) to finance the purchase of Dutch residential mortgage loans secured over properties located in the Netherlands. Additionally, the Issuer issued Class C notes, which are noncollateralised and whose proceeds will be used to fund a reserve fund.

Credit support to the Class A1 notes is sized at 31.0% and provided by the subordination of the Class A2 and Class B notes and the nonamortising reserve fund. Credit support to the Class A2 notes is sized at 10.5% and provided by the subordination of the Class B notes and the nonamortising reserve fund. The reserve fund was funded at 1.0% of the Class A1, Class A2, and Class B notes’ initial balance.

Further liquidity support for the Class A1 and Class A2 notes is provided through a cash advance facility, along with a priority of payments allowing principal to be borrowed to support revenue items with a corresponding debit to the appropriate principal deficiency ledger. The cash advance facility will amortise, with no performance conditions attached. It is sized at 1.5% of the Class A1 and Class A2 notes’ outstanding balance with a floor of 1.0% of the Class A notes’ initial balance. The cash advance facility is a 364-day renewable facility and, if it is not renewed, it will be drawn by the Issuer.

RATING RATIONALE
As of 31 October 2022, the portfolio consisted of 5,146 loan parts granted to 2,508 borrowers with an aggregate principal balance of EUR 526.5 million. The weighted-average (WA) seasoning of the portfolio was 1.4 years with a WA residual maturity of 27.9 years. The WA loan-to-value ratio of the portfolio was 83.3%. 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 16.7% interest-only loans, and 3.5% of the loans were granted to self-employed borrowers. As of the cut-off date, all mortgage loans were performing.

All loans pay a fixed rate of interest with the most common reset frequencies being 20 and 30 years. In comparison, the Class A notes pay an interest rate linked to three-month Euribor, which resets on a quarterly basis. The Issuer’s interest rate risk exposure is hedged through a total return swap agreement with Coöperatieve Rabobank U.A. Based on its rating and on the collateral posting provisions included in the documentation, DBRS Morningstar considers the risk of such counterparty to be consistent with the ratings assigned, in accordance with its “Derivative Criteria for European Structured Finance Transactions” methodology.

Further advances are allowed only until May 2028 and are subject to certain annual quantitative limits. In addition, the sale of further advance receivables is subject to certain conditions, as well as the general pool eligibility criteria, which limits the deterioration of the pool quality. DBRS Morningstar reviewed these conditions and considered them in its analysis.

In case further advances are granted beyond these limits, MeDirect (the seller) has undertaken to repurchase the relevant loans, paying a price that is at least equal to the outstanding principal and accrued interest. If the seller does not comply with this obligation, the Issuer has the option to sell the relevant loans at market value to other investors in the originator platform. In this case, the Issuer may suffer a loss (market value shortfall amount), which will result in a debit to the principal deficiency ledger and can be covered via excess spread, if available, as per the transaction priority of payments. The maximum market value shortfall amount is defined in the transaction documents as 3.38% of the initial pool balance: the loans cannot be sold at a loss once the cumulative market value shortfall amount has exceeded this level.

BNG Bank N.V. is the Issuer account bank. Based on DBRS Morningstar’s private rating on the account bank and the replacement provisions included in the transaction documents, DBRS Morningstar considers the risk of such counterparty to be consistent with the ratings assigned, in accordance with its “Legal Criteria for European Structured Finance Transactions” methodology.

HollandWoont (the originator) serviced and originated the mortgages, with Quion Services B.V. (Quion) acting as the subservicer.

DBRS Morningstar based its ratings primarily on the following:
-- The transaction capital structure, form, and sufficiency of available credit enhancements and liquidity provisions.
-- The credit quality of the mortgage loan portfolio and the ability of the servicer to perform collection activities. DBRS Morningstar calculated portfolio default rates (PDs), 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 notes according to the terms of the transaction documents. DBRS Morningstar analysed the transaction cash flows using PD and LGD outputs provided by DBRS Morningstar’s European RMBS Insight Model. DBRS Morningstar analysed transaction cash flows using Intex DealMaker.
-- 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.
-- 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.

ENVIRONMENTAL, SOCIAL, GOVERNANCE CONSIDERATIONS
General Considerations

Social (S) Factors
The portfolio is exposed to loans guaranteed by the Dutch mortgage scheme National Mortgage Guarantee (NHG). This scheme supports home ownership in the Netherlands by providing low interest rate loans for the purchase of properties up to EUR 355,000 (January 2022).

Of the loan parts in the pool, 100% are NHG guaranteed. DBRS Morningstar considered that the presence of NHG loans in the portfolio is a social factor as outlined within the “DBRS Morningstar Criteria: Approach to Environmental, Social, and Governance Risk Factors in Credit Ratings”. DBRS Morningstar assumed reduced loss severities for loans backed by an NHG guarantee as outlined in its “European RMBS Insight: Dutch Addendum” methodology available at https://www.dbrsmorningstar.com/research/393357/european-rmbs-insight-dutch-addendum. This is credit positive and has a relevant effect on the ratings.

There were no Environmental/Governance factors that had a significant or relevant effect on the credit analysis.

Sensitivity Analysis: To assess the impact of changing the transaction parameters on the ratings, DBRS Morningstar considered the following stress scenarios, as compared to the parameters used to determine the ratings (the base case):

-- In respect of the Class A1 and A2 notes, a PD of 22.6% and LGD of 24.8% (which take into consideration the maximum market value shortfall amount), corresponding to the AAA (sf) rating scenario, were stressed assuming a 25% and 50% increase in the PD and LGD.

DBRS Morningstar concludes the following impact on the Class A1 notes:
-- 25% increase of the PD, ceteris paribus, would lead to a downgrade to AAA (sf);
-- 50% increase of the PD, ceteris paribus, would lead to a downgrade to AAA (sf);
-- 25% increase of the LGD, ceteris paribus, would lead to a downgrade to AAA (sf);
-- 50% increase of the LGD, ceteris paribus, would lead to a downgrade to AAA (sf);
-- 25% increase of the PD and 25% increase of the LGD, ceteris paribus, would lead to a downgrade to AAA (sf);
-- 50% increase of the PD and 25% increase of the LGD, ceteris paribus, would lead to a downgrade to AAA (sf);
-- 25% increase of the PD and 50% increase of the LGD, ceteris paribus, would lead to a downgrade to AAA (sf);
-- 50% increase of the PD and 50% increase of the LGD, ceteris paribus, would lead to a downgrade to AAA (sf).

DBRS Morningstar concludes the following impact on the Class A2 notes:
-- 25% increase of the PD, ceteris paribus, would lead to a downgrade to AAA (sf);
-- 50% increase of the PD, ceteris paribus, would lead to a downgrade to AAA (sf);
-- 25% increase of the LGD, ceteris paribus, would lead to a downgrade to AAA (sf);
-- 50% increase of the LGD, ceteris paribus, would lead to a downgrade to AAA (sf);
-- 25% increase of the PD and 25% increase of the LGD, ceteris paribus, would lead to a downgrade to AAA (sf);
-- 50% increase of the PD and 25% increase of the LGD, ceteris paribus, would lead to a downgrade to AAA (sf);
-- 25% increase of the PD and 50% increase of the LGD, ceteris paribus, would lead to a downgrade to AAA (sf);
-- 50% increase of the PD and 50% increase of the LGD, ceteris paribus, would lead to a downgrade to AA (high) (sf).
