DBRS Morningstar Confirms Credit Rating on Wendelstein 2017-1 UG (haftungsbeschränkt) Following Amendment

DBRS Ratings GmbH (DBRS Morningstar) confirmed its A (high) (sf) credit rating on the Class A Notes issued by Wendelstein 2017-1 UG (haftungsbeschränkt) (the Issuer).

The credit rating addresses the timely payment of interest and the ultimate repayment of principal on or before the legal final maturity date in December 2081.

The credit rating confirmation follows a full review of the transaction and is based on the following analytical considerations:

-- Portfolio performance, in terms of delinquencies, defaults, and losses, as of the September 2023 payment date;
-- Probability of default (PD), loss given default (LGD), and expected loss assumptions on the collateral pool;
-- Current available credit enhancement to the Class A Notes to cover the expected losses at the A (high) (sf) credit rating level;
-- Absence of revolving termination events; and
-- An amendment to the transaction extending the revolving period by an additional three years until December 2026, and reducing the weighted average portfolio interest rate to 1.90% from 2.05%, executed on 27 November 2023.

The transaction is a securitisation of German mortgage loans originated and serviced by DB AG and its subsidiaries, Deutsche Bank Bauspar AG (DB Bauspar) and Deutsche Bank Privat- und Firmenkundenbank AG (DB Private). In May 2019, DB Bauspar integrated with BHW Bausparkasse AG and, in May 2020, DB Private merged into DB AG.

The transaction closed in November 2017 and included an initial three-year revolving period that was extended for an additional three years in November 2022 and is currently scheduled to terminate on 31 December 2023. During the revolving period, additional receivables can be added to the portfolio, subject to compliance with the substitution criteria.

PORTFOLIO PERFORMANCE
As of September 2023, loans that were two to three months in arrears represented 0.08% of the outstanding portfolio balance, up from 0.05% in September 2022. The 90+ days delinquency ratio marginally increased to 0.06%, up from 0.05% in the same period. The cumulative default ratio remained at 0.4% and the cumulative loss ratio remained at 0.0%.

PORTFOLIO ASSUMPTIONS AND KEY DRIVERS
DBRS Morningstar conducted a loan-by-loan analysis of the collateral pool and maintained its base case PD and LGD assumptions of 3.5% and 10.4%, respectively, reflecting the potential portfolio migration based on replenishment criteria set forth in the transaction legal documents for the revolving period.

CREDIT ENHANCEMENT
As of the September 2023 payment date, credit enhancement to the Class A Notes remained at 8.0%, stable since DBRS Morningstar’s initial credit rating, because the transaction remains in the revolving period.

The transaction benefits from a liquidity facility that currently totals EUR 216.2 million. The liquidity facility is available for the Issuer to meet any shortfalls in the payment of senior fees and interest on the Class A Notes.

DB AG acts as the account bank for the transaction. Based on DB AG’s reference credit rating of A (high), which is one notch below its COR of AA (low), 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 A (high) (sf) credit rating assigned to the Class A Notes, as described in DBRS Morningstar's "Legal Criteria for European Structured Finance Transactions" methodology.

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

DBRS Morningstar’s credit ratings do not address non-payment risk associated with contractual payment obligations contemplated in the applicable transaction documents that are not financial obligations.

DBRS Morningstar’s long-term credit ratings provide opinions on risk of default. DBRS Morningstar considers risk of default to be the risk that the 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
There were no Environmental/Social/Governance factors that had a significant or relevant effect on the credit analysis.

The principal methodology applicable to the credit rating is the “Master European Structured Finance Surveillance Methodology” (16 October 2023), https://www.dbrsmorningstar.com/research/421938/master-european-structured-finance-surveillance-methodology-request-for-comment

Other methodologies referenced in this transaction are listed at the end of this press release.

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 continues to consider potential portfolio migration based on replenishment criteria set forth in the transaction legal documents.

A review of the transaction legal documents was not conducted as the legal documents have remained unchanged since the most recent credit rating action.

Sensitivity Analysis: To assess the impact of changing the transaction parameters on the credit rating, DBRS Morningstar considered the following stress scenarios as compared with the parameters used to determine the credit rating (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 are 3.5% and 10.4%, 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 assumptions. For example, if the LGD increases by 50%, the credit rating on the Class A Notes would be expected to remain at A (high) (sf), assuming no change in the PD. If the PD increases by 50%, the credit rating on the Class A Notes would be expected to remain at A (high) (sf), assuming no change in the LGD. Furthermore, if both the PD and LGD increase by 50%, the credit rating on the Class A Notes would also be expected to fall to A (low) (sf).

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