DBRS Morningstar Confirms the Rating on Wendelstein 2017-1 UG (haftungsbeschränkt)

RMBS
April 09, 2020

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

The rating on the Class A Notes addresses the timely payment of interest and ultimate payment of principal on or before the legal final maturity date in 15 December 2081.

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.
-- Probability of default (PD), loss given default (LGD), and expected loss assumptions on the collateral pool.
-- Current available credit enhancement to the notes to cover the expected losses at its A (sf) rating level.
-- No revolving termination events have occurred.

Wendelstein 2017-1 UG (haftungsbeschränkt) is a securitisation of German mortgage loans originated and serviced by Deutsche Bank AG (DB AG) and its subsidiaries, Deutsche Bank BHW Bausparkasse AG(DB BHW) and Deutsche Bank Privat- und Firmenkundenbank AG (DB Private). The transaction is currently in its replenishment period, which is scheduled to end on 31 December 2020 or when a Replenishment Termination Event occurs.

PORTFOLIO PERFORMANCE
As of March 2020, loans two- to three-months in arrears represented 0.03% of the outstanding portfolio balance, down from 0.04% in March 2019. The 90+ delinquency ratio was 0.06%, up from 0.04% in the same period, and the cumulative default ratio was 0.23%.

PORTFOLIO ASSUMPTIONS AND KEY DRIVERS
DBRS Morningstar conducted a loan-by-loan analysis of the revolving pool of receivables. As the transaction is still revolving and the performance is within DBRS Morningstar’s expectations, DBRS Morningstar maintained its base case PD and LGD assumptions at 2.8% and 34.2%, respectively.

CREDIT ENHANCEMENT
As of the March 2020 payment date, credit enhancement to the Class A Notes was 8.0%, stable since the DBRS Morningstar initial rating due to the transaction replenishment period ending in December 2020. The credit enhancement is provided through the subordination of the Class B Notes.

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

DB Private acts as the account bank for the transaction. Based on DBRS Morningstar’s private rating of DB Private, 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.

DBRS Morningstar analysed the transaction structure in Intex DealMaker.

To assess the impact of changing the transaction parameters on the rating, DBRS Morningstar considered the following stress scenarios as compared with the parameters used to determine the 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 rating.
-- The base case PD and LGD of the current pool of loans for the Issuer are 2.8% and 34.2%, 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 remain at A (sf), assuming no change in the PD. If the PD increases by 50%, the rating of the Class A Notes would be expected to remain at A (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 still be expected to remain at A (sf).

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