Morningstar DBRS Confirms Credit Rating on Bastion 2021-1 NHG B.V.

DBRS Ratings GmbH (Morningstar DBRS) confirmed its AAA (sf) credit rating on the Class A notes issued by Bastion 2021-1 NHG B.V. (the Issuer).

The credit rating on the Class A notes addresses the timely payment of interest and ultimate repayment of principal on or before the legal final maturity date.

The confirmation follows an annual review of the transaction and is based on the following analytical considerations:
-- Portfolio performance, in terms of delinquencies, defaults and losses, as of the November 2023 payment date.
-- Portfolio default rate (PD), loss given default (LGD), and expected loss assumptions on the remaining receivables.
-- Current available credit enhancement to the Class A notes to cover the expected losses at the AAA (sf) credit rating level.

The Issuer is a securitisation of Dutch prime mortgages originated by HollandWoont B.V., secured over owner-occupied residential properties located in the Netherlands. The portfolio is also serviced by HollandWoont B.V., with Quion Services B.V. acting as the sub-servicer.

PORTFOLIO PERFORMANCE
As of 30 October 2023, loans two to three months in arrears represented 0.0% of the outstanding portfolio balance, stable since November 2022. Loans more than three months in arrears represented 0.0%, down from 0.1% in November 2022. The cumulative default ratio was 0.0%.

PORTFOLIO ASSUMPTIONS AND KEY DRIVERS
DBRS Morningstar conducted a loan-by-loan analysis of the remaining pool of receivables and has updated its base case PD and LGD assumptions at the B (sf) credit rating level to 1.9% and 5.9%, respectively.

CREDIT ENHANCEMENT
As of the November 2023 payment date, credit enhancement to the Class A notes was 13.0%, up from 10.5% at the Morningstar DBRS initial credit rating. Credit enhancement consists of subordination of the junior notes and the general reserve fund.

The nonamortising general reserve fund covers senior fees, senior swap payments, interest on the Class A notes, and principal losses via the principal deficiency ledger on the Class A notes. It is currently funded to its target level of EUR 4.1 million, equal to 1% of the initial Class A and Class B notes balance.

The transaction also benefits from a renewable cash advance facility (CAF) provided by BNG Bank N.V. (BNG) equal to 1.5% of the outstanding Class A notes balance, subject to a floor of 1.0% of the initial Class A notes balance. The maximum available amount of the CAF is currently EUR 4.5 million and can be drawn on to cover senior fees, senior swap payments, and Class A interest.

BNG acts as the account bank for the transaction. Based on the Morningstar DBRS private credit rating of BNG, the downgrade provisions outlined in the transaction documents, and other mitigating factors inherent in the transaction structure, Morningstar DBRS considers the risk arising from the exposure to the account bank to be consistent with the credit rating assigned to the Class A notes, as described in Morningstar DBRS’ "Legal Criteria for European Structured Finance Transactions" methodology.

MeDirect Bank NV/SA (MeDirect) acts as the swap counterparty for the transaction, and Coöperatieve Rabobank U.A. (Rabobank) acts as the back-up swap counterparty and credit support provider. MeDirect is not rated by Morningstar DBRS; however, Morningstar DBRS’ public Long-Term Critical Obligations Rating of Rabobank at AA (high) is consistent with the First Rating Threshold as described in Morningstar DBRS’ "Derivative Criteria for European Structured Finance Transactions" methodology.

Morningstar DBRS’ credit rating on the notes addresses the credit risk associated with the identified financial obligations in accordance with the relevant transaction documents.

Morningstar DBRS’ credit rating on the notes also addresses the credit risk associated with the increased rate of interest applicable to the notes if the notes are not redeemed on the Optional Redemption Date (as defined in and) in accordance with the applicable transaction documents.

Morningstar DBRS’ credit rating does not address nonpayment risk associated with contractual payment obligations contemplated in the applicable transaction documents that are not financial obligations.

Morningstar DBRS’ long-term credit ratings provide opinions on risk of default. Morningstar DBRS considers risk of default to be the risk that an issuer will fail to satisfy the financial obligations in accordance with the terms under which a long-term obligation has been issued.

ENVIRONMENTAL, SOCIAL, GOVERNANCE CONSIDERATIONS
Morningstar DBRS considers that the Nationale Hypotheek Garantie (NHG) guarantee backing the loans in the pool is a significant Social factor (Social Impact of Product & Services) as outlined within the Morningstar DBRS’ framework – “Morningstar DBRS Criteria: Approach to Environmental, Social, and Governance Risk Factors in Credit Ratings”. Morningstar DBRS assumed reduced loss severity for loans backed by an NHG guarantee as outlined in its “European RMBS Insight: Dutch Addendum” methodology. This is credit positive and affects the credit rating. Please also refer to https://dbrs.morningstar.com/research/366268 for more details.

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

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

-- Morningstar DBRS 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) credit rating level are 1.9% and 5.9%, respectively.
-- The risk sensitivity overview below illustrates the credit ratings expected if the PD and LGD increase by a certain percentage over the base case assumption.

Class A Risk Sensitivity:
-- 25% increase in LGD, expected credit rating of AAA (sf)
-- 50% increase in LGD, expected credit rating of AAA (sf)
-- 25% increase in PD, expected credit rating of AAA (sf)
-- 50% increase in PD, expected credit rating of AAA (sf)
-- 25% increase in PD and 25% increase in LGD, expected credit rating of AAA (sf)
-- 25% increase in PD and 50% increase in LGD, expected credit rating of AAA (sf)
-- 50% increase in PD and 25% increase in LGD, expected credit rating of AAA (sf)
-- 50% increase in PD and 50% increase in LGD, expected credit rating of AAA (sf)
