DBRS Morningstar Assigns Provisional Ratings to Certain Retained Tranche Amounts of Manitoulin USD Ltd., Algonquin 2022-4

Structured Credit
November 01, 2022

DBRS, Inc. (DBRS Morningstar) assigned the following provisional ratings to the Tranche Retained Portion Initial Notional Amount of the Senior Tranche, the Tranche B, the Tranche C, and the Tranche D (collectively, the Retained Tranche Amounts) of two unexecuted, unfunded financial guarantees (the Financial Guarantees) of Manitoulin USD Ltd., Algonquin 2022-4 with respect to a portfolio of primarily U.S. and Canadian senior secured and senior unsecured loans originated or managed by the Bank of Montreal (BMO or the Beneficiary; rated AA with a Stable trend by DBRS Morningstar):

-- Senior Tranche at AAA (sf)
-- Tranche B at AA (high) (sf)
-- Tranche C at A (sf)
-- Tranche D at BBB (low) (sf)

The provisional ratings on the Retained Tranche Amounts address the likelihood of a reduction to the respective Tranche Retained Portion Initial Notional Amount (as defined in the Financial Guarantees) resulting from obligor defaults within the guaranteed portfolio during the period from the Effective Date until the Scheduled Termination Date. For obligors within the guaranteed portfolio, default events are limited to payment default, insolvency, and restructuring events.

The ratings take into consideration only the creditworthiness of the reference portfolio. The ratings do not address counterparty risk nor the likelihood of any event of default or termination events under the agreement occurring. BMO bought protection under a similar executed financial guarantee for certain issued notes (the Notes) but has not executed contracts related to the tranche notional amounts.

Regarding the Notes, BMO did not request that DBRS Morningstar assign ratings to the Notes to be issued under the executed financial guarantee. The payment of principal and interest (the Guarantee Fee Amount, as defined in the executed financial guarantee referenced above) on the Notes is subject to additional counterparty credit risk associated with the Beneficiary’s ability to pay such amounts. As a result, if DBRS Morningstar were to rate such Notes, even if they are pari passu with a related Retained Tranche Amount, DBRS Morningstar’s credit rating on the Notes may be different than the credit ratings assigned to the related Retained Tranche Amounts.

DBRS Morningstar expects its ratings to remain provisional until the underlying agreements are executed. BMO may have no intention of executing the Financial Guarantees. DBRS Morningstar will maintain and monitor the provisional ratings throughout the life of the transaction or while it continues to receive performance information.

To assess portfolio credit quality, DBRS Morningstar may provide a credit estimate, internal assessment, or ratings mapping of BMO’s internal ratings model. Credit estimates, internal assessments, and ratings mappings are not ratings; rather, they represent an abbreviated analysis, including model-driven or statistical components of default probability for each obligor that is used in assigning a rating to a facility sufficient to assess portfolio credit quality.

The provisional ratings are the result of DBRS Morningstar’s review of the transaction structure and draft Financial Guarantees of Manitoulin USD Ltd., a corporation established under the Canada Business Corporations Act. Manitoulin USD Ltd., Algonquin 2022-4 is a synthetic risk transfer transaction with BMO as the Beneficiary.

The ratings reflect the following considerations:

(1) The draft Financial Guarantees.
(2) The integrity of the transaction structure.
(3) DBRS Morningstar’s assessment of the portfolio quality.
(4) Adequate credit enhancement to withstand projected collateral loss rates.

DBRS Morningstar analyzed the transaction using its CLO Asset Model, based on certain reference portfolio characteristics, including Eligibility Criteria and Replenishment Criteria, as defined per the draft Financial Guarantees. The initial reference portfolio consists of well-diversified corporate and commercial loans across various industries and rating levels. The analysis produced satisfactory results, which supported the provisional ratings on the Retained Tranche Amounts.

The transaction assumptions consider DBRS Morningstar’s baseline macroeconomic scenarios for rated sovereign economies, available in its commentary “Baseline Macroeconomic Scenarios for Rated Sovereigns: September 2022 Update,” published on September 19, 2022 ( These baseline macroeconomic scenarios replace DBRS Morningstar’s moderate and adverse Coronavirus Disease (COVID-19) pandemic scenarios, which were first published in April 2020.

There were no environmental, social, or governance (ESG) factors that had a significant or relevant effect on the credit analysis.

This rating is endorsed by DBRS Ratings Limited for use in the United Kingdom, and by DBRS Ratings GmbH for use in the European Union, respectively. The following additional regulatory disclosures apply to endorsed ratings:

Each of the principal asset class methodologies employed in the analysis addressed one or more particular risks or aspects of the rating and were factored into the rating decision. Specifically, for the recovery rate, DBRS Morningstar applied the senior secured and senior unsecured recovery rates defined in its “Rating CLOs and CDOs of Large Corporate Credit” (January 26, 2022) methodology. DBRS Morningstar applies different recovery rates depending on the recovery tier and seniority.

DBRS Morningstar used its CLO Asset Model to determine expected default rates for the portfolio at each rating level. To determine the credit risk of each underlying reference obligation, DBRS Morningstar relied on either public ratings or a ratings mapping to DBRS Morningstar ratings of BMO’s internal ratings models. The mapping was completed in accordance with DBRS Morningstar’s “Mapping Financial Institution Internal Ratings to DBRS Morningstar Ratings for Global Structured Credit Transactions” (February 24, 2022) methodology.

This rating concerns an expected to be issued new financial instrument. This is the first DBRS Morningstar rating on this financial instrument.
