DBRS Morningstar Assigns Rating to Boursorama Master Home Loans France

DBRS Ratings GmbH (DBRS Morningstar) assigned a rating of AA (sf) to the Class A Notes issued by Boursorama Master Home Loans France (the Issuer). The notes are collateralised by a portfolio of French residential loans originated by Boursorama, SA (the originator or the servicer). The portfolio of loans includes ancillary rights, which consist of Crédit Logement, S.A. guarantees securing 100% of the loans.

The Issuer issued two tranches of mortgage-backed securities (the Class A and Class B Notes) to finance the purchase of the portfolio. DBRS Morningstar does not rate the Class B Notes also issued in this transaction.

The rating assigned to the Class A Notes addresses the timely payment of interest and the ultimate payment of principal on or before the final maturity date in December 2066.

The Issuer was established as a fond commun de titrisation governed by French regulations. The transaction features a master trust structure with a four-year revolving period during which time the Issuer may issue additional series of Class A Notes to acquire additional home loans (including construction receivables) and their ancillary rights from the seller, subject to the availability of principal collections, eligibility criteria, and as long as no revolving period termination event has occurred, up to a maximum Class A principal outstanding amount of EUR 10 billion. On each subsequent issue date, the Class B Notes shall be mandatorily redeemed in full in accordance with the revolving period priority of payments and new Class B Notes shall be issued, maintaining the initial credit enhancement.

After the revolving period ends in December 2026, the notes will begin to amortise according to the normal amortisation period priority of payments. If an accelerated amortization event or a sequential amortisation event occurs and is continuing, the Class B Notes will not amortise until the Class A Notes have been redeemed in full. France Titrisation will manage the transaction.

At closing, the Class A Notes benefit from credit enhancement of 5.0% (calculated as a percentage of the portfolio), consisting of the subordination of the Class B Notes. The transaction also features a general reserve fund, which shall provide liquidity support for the payments of senior fees and interest on the Class A Notes, amortising in line with their outstanding balance and fully funded at closing by the originator. Any released amounts following the reserve’s amortisation will flow through the priority of payments.

The transaction structure also benefits from a commingling reserve, fully funded by the originator, made available in the event of a servicer disruption that results in collections not being available on any payment date. Such a reserve, set at 1.2% of the outstanding balance of the notes, shall be nonamortising.

Liquidity for the Class A Notes is also supported by the combined waterfall structure, whereby all monthly collections are distributed through a single priority of payments (principal to pay interest).

As of 31 October 2022, the portfolio consisted of 4,217 mortgage loans granted to 4,190 borrowers. As of the same date, the total current balance of the portfolio was EUR 2.7 billion and the average loan balance (per borrower) was EUR 644,387. The weighted-average (WA) seasoning of the portfolio was 1.8 years with a WA time to maturity of 21.3 years. The WA original loan-to-value ratio (LTV) of the portfolio stood at 86.3% whereas the WA current LTV was 77.4%. The portfolio is concentrated in Île-de-France, representing 81.7% of the pool balance.

The entire portfolio pays a fixed rate of interest, with a WA interest rate of 0.8%. The coupon on the notes is also fixed at 0.35% for the Class A Notes and 1.50% for the Class B Notes.

The transaction account bank, cash manager, custodian, and paying agent is Société Générale, S.A. Based on DBRS Morningstar’s rating on such entity and the account bank replacement provisions included in the transaction documents, DBRS Morningstar considers the risk associated with such counterparty to be consistent with the ratings assigned, in accordance with its “Legal Criteria for European Structured Finance Transactions”.

Sensitivity Analysis: 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):

-- In respect of the Class A Notes, a PD of 17.22% and LGD of 8.73%, corresponding to the AA (sf) rating scenario, was stressed assuming a 25% and 50% increase in the PD and LGD, respectively.

DBRS Morningstar concludes the following impact on the Class A Notes:
-- 25% increase of the PD, ceteris paribus, would not lead to a rating change;
-- 50% increase of the PD, ceteris paribus, would not lead to a rating change;
-- 25% increase of the LGD, ceteris paribus, would not lead to a rating change;
-- 50% increase of the LGD, ceteris paribus, would not lead to a rating change;
-- 25% increase of the PD and 25% increase of the LGD, ceteris paribus, would not lead to a rating change;
-- 50% increase of the PD and 25% increase of the LGD, ceteris paribus, would lead to a downgrade to AA (low) (sf);
-- 25% increase of the PD and 50% increase of the LGD, ceteris paribus, would not lead to a rating change;
-- 50% increase of the PD and 50% increase of the LGD, ceteris paribus, would lead to a downgrade to AA (low) (sf).
