DBRS Morningstar Assigns Provisional Credit Ratings to Stresa Securitisation S.r.l.

RMBS

November 23, 2023

DBRS Ratings GmbH (DBRS Morningstar) assigned provisional credit ratings to the residential mortgage-backed notes to be issued by Stresa Securitisation S.r.l. (the Issuer) as follows:

-- Class A at AA (sf)
-- Class B at A (sf)
-- Class C at BBB (sf)
-- Class D at BB (sf)

The credit rating on the Class A notes addresses the timely payment of interest and the ultimate repayment of principal. The credit ratings on the Class B, Class C and Class D notes address the ultimate payment of interest and principal.

DBRS Morningstar does not rate the Class R and Class Z notes also expected to be issued in this transaction.

CREDIT RATING RATIONALE
The Issuer is a bankruptcy-remote special-purpose vehicle incorporated in the Republic of Italy. The Issuer will use the proceeds of the notes to resecuritise an existing portfolio of mostly prime and performing Italian owner-occupied (OO) mortgage loans secured over properties in Italy.

Meliorbanca S.p.A. (Meliorbanca; the originator) originated the mortgage loans included in this portfolio in 2006 and 2007. Meliorbanca merged into BPER Banca S.p.A. (BPER) in 2011. Following Commerzbank group's purchase, the portfolio was securitised under Borromeo Finance S.r.l. (Borromeo). Borromeo subsequently sold the portfolio to Stresa, a new special-purpose vehicle sponsored by the Fortress Investment Group LLC (Fortress) with two separate transfers in 2017 and 2019. The purpose of the newly issued notes is to repay the outstanding notes that Stresa issued to finance the portfolio purchases from Borromeo.

doNext S.p.A. (doNext) has been acting as the servicer for the portfolio since March 2011 and will continue to service the portfolio after the new notes issuance. DBRS Morningstar reviewed doValue S.p.A.'s (doNext's parent company) servicing practices.

The portfolio size as of June 2023 amounts to EUR 158 million, with a weighted average (WA) current loan-to-value (CLTV) of 65.5% (calculated by DBRS Morningstar) and a WA seasoning of approximately 16 years. Roughly 13% of the portfolio is equal to or more than three months in arrears. The majority of the portfolio corresponds to floating-rate for life loans tracking six-month Euribor. Although these loans track the same index and reset every three months, the index calculation method is different depending on the product type. In most cases, the index is calculated as the average of the last two months before each quarterly reset. The WA coupon of the portfolio equals 4.9%.

Liquidity for the Class A notes will be supported by a liquidity reserve fund (LRF), which will be fully funded at closing and then amortise in line with the referred class of notes, which shall also feature a floor equal to 2% of the Class A notes' initial balance. The notes' terms and conditions allow interest payments other than on the Class A notes to be deferred if the available funds are insufficient. However, when the Class B notes are the most senior class of notes outstanding, deferral is not possible for the Class B notes.

Furthermore, Deutsche Bank AG/London Branch shall act as the Issuer Account Bank, and BPER Banca S.p.A. shall be appointed as the Collection Account Bank. While the former is privately rated by DBRS Morningstar, the latter is publicly rated with a long-term critical obligations rating (COR) of A (low) and a long-term issuer rating (IR) of BBB, both with a stable trend. Both entities meet the eligible ratings in structured finance transactions and are consistent with DBRS Morningstar's “Legal Criteria for European Structured Finance Transactions” methodology.

The notes expected to be issued in this transaction feature a coupon cap meaning that the coupon on the rated notes cannot exceed the maximum coupon established at closing. Payments made by the Issuer above the coupon cap are junior in the waterfall and for that reason DBRS Morningstar credit ratings do not address the payment of this additional amount.

Credit enhancement for the Class A notes is calculated at 19.25% and is provided by the subordination of the Class B to Class D notes and Class Z notes. Credit enhancement for the Class B notes is calculated at 15.50% and is provided by the subordination of the Class C to Class D notes and Class Z notes. Credit enhancement for the Class C notes is calculated at 11.75% and is provided by the subordination of the Class D and Class Z notes. Credit enhancement for the Class D notes is calculated at 8.50% and is provided by the Class Z notes.

DBRS Morningstar based its credit ratings primarily on the following considerations:
-- The transaction capital structure, including the form and sufficiency of available credit enhancement and liquidity
provisions.
-- The credit quality of the mortgage portfolio and the servicer’s ability to perform collection and resolution activities.
-- DBRS Morningstar calculated probability of default (PD), loss given default (LGD), and expected loss (EL) outputs on the mortgage portfolio, which DBRS Morningstar uses as inputs into its cash flow tool. DBRS Morningstar analysed the mortgage portfolio in accordance with its “European RMBS Insight Methodology” and “European RMBS Insight: Italian Addendum”.
-- The transaction’s ability to withstand stressed cash flow assumptions and repay investors in accordance with the terms and conditions of the notes.
-- The exposure to the transaction account bank and the downgrade provisions outlined 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.
-- The sovereign rating of the Republic of Italy, rated BBB (high) with a Stable trend by DBRS Morningstar, as of the date of this press release.

DBRS Morningstar’s credit rating on the rated notes addresses the credit risk associated with the identified financial obligations in accordance with the relevant transaction documents. The associated financial obligations are the related Interest Amounts and the related Class Balances.

DBRS Morningstar’s credit rating does not address non-payment risk associated with contractual payment obligations contemplated in the applicable transaction document(s) that are not financial obligations. For example, the ratings on the applicable notes do not address the related Additional Coupon Cap Payments.

DBRS Morningstar’s long-term credit ratings provide opinions on risk of default. DBRS Morningstar 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.
