DBRS Morningstar Assigns Provisional Ratings to Classic RMBS Trust, Series 2022-1

DBRS Limited (DBRS Morningstar) assigned provisional ratings to the Mortgage Pass-Through Notes, Series 2022-1 to be issued by Classic RMBS Trust (the Issuer) as follows:

-- AAA (sf) to the Class A Mortgage Pass-Through Notes, Series 2022-1 (the Class A Notes)
-- A (low) (sf) to the Class B Mortgage Pass-Through Notes, Series 2022-1 (the Class B Notes; together with the Class A Notes, the Rated Notes)

The finalization of the ratings is contingent upon receipt of final documents conforming to information already received by DBRS Morningstar.

The Class Z Mortgage Pass-Through Notes, Series 2022-1 are not rated by DBRS Morningstar.

DBRS Morningstar considered the following factors in its analysis:

(1) The high level of credit enhancement provided by subordination (15% and 5% initial subordination for the Class A Notes and Class B Notes, respectively).

(2) A bankruptcy-remote structure that provides increasing enhancement to the Rated Notes as principal is repaid sequentially. Additional protections include a Servicing Reserve Account and excess collections that are directed toward repayment of the Rated Notes upon the occurrence of a Trigger Event.

(3) The collateral comprises a pool of approximately $500.2 million first-lien fixed-rate uninsured Canadian residential mortgages with a weighted-average loan-to-value ratio of 71.2% and a weighted-average credit score of 745 (the Mortgage Pool), in each case, as of the Cut-Off Date. The Mortgage Pool also benefits from 14 months of seasoning since initial origination and excludes defaulted or delinquent mortgages and mortgages that were under deferral plans since the later of its origination date and latest renewal date. All of the loans in the Mortgage Pool are originated and serviced by Home Trust Company (Home Trust).

(4) The mortgages are underwritten manually with full documentation, including verified income and full appraisal; are in compliance with Home Trust's underwriting guidelines and Residential Mortgage Underwriting Policy, as in effect at the time of origination; and are in accordance with the Office of the Superintendent of Financial Institutions’ Guideline B-20, as in effect at the time of origination.

(5) An independent third-party due-diligence firm conducted credit, renewal, payment history, data integrity, and property valuation reviews, as applicable, on 30.2% of the loans in the pool (by loan count as of the Cut-Off Date). The results of the reviews were satisfactory.

DBRS Morningstar uses the Canadian residential mortgage-backed securities (RMBS) model that calculates estimated default frequency (more than 90 days in arrears), loss severity, and expected loss on a loan-level basis. The RMBS model output does not include the risk of mortgage default at maturity (i.e., balloon risk). Balloon risk is considered to be low in this transaction because of the strong asset quality, proven refinancing liquidity during the 2008–09 financial crisis, and structural features for loans that are not renewed at maturity. If a loan has not been renewed within the Mortgage Pool or renewed or refinanced with Home Trust or any other lender prior to its maturity date and remains unpaid on its maturity date, the Servicer (or a Replacement Servicer) will extend the maturity date of the mortgage up to six months at a rate equal to the greater of the mortgage rate as of the Cut-Off Date or the Seller’s prevailing posted mortgage rate at the time of the extension, in order to prevent the mortgage from becoming delinquent or defaulted at maturity. To assess balloon risk, DBRS Morningstar nevertheless considers the probability of no lender liquidity at the end of the loan tenure and a hypothetical percentage of loan defaults as a result of nonrenewal. The balloon risk is in addition to the credit risk estimated by the RMBS model. When determining the loss severity of loans that default as a result of nonrenewal, as such borrowers have been current on their mortgage payments and the timing of default is known, DBRS Morningstar considers scheduled mortgage payments and a certain level of house price appreciation during the mortgage term. After taking the balloon risk into account, DBRS Morningstar’s analysis indicates that the 15% initial credit enhancement available to the Class A Notes provides substantial protection compared with the total expected loss under a AAA (sf) stress.

With the RMBS model results and adjustment for balloon risk, DBRS Morningstar runs a proprietary cash flow engine that incorporates the transaction structure and assumptions for timing of default, interest rates, and prepayments. The result was that the Rated Notes, with the proposed structure, could withstand each stress scenario with no loss. The Issuer’s ability to repay interest and principal of the Rated Notes is consistent with the respective ratings.

The Seller and Servicer, Home Trust, is rated BBB (low) and R-2 (middle) with Stable trends by DBRS Morningstar as of March 26, 2021. It is a federally regulated trust company with $23.4 billion of loans under administration as at September 2021.
