DBRS Finalizes Provisional Ratings on MCAP RMBS Issuer Corporation, Series 2018-2

DBRS Limited (DBRS) finalized the provisional ratings on the Mortgage Pass-Through Certificates, Series 2018-2 issued by MCAP RMBS Issuer Corporation (the Issuer) as follows:

-- AAA (sf) on the Class A Certificates
-- AA (high) (sf) on the Class B Certificates (collectively, with the Class A Certificates, the Rated Certificates)

The Class Z Certificates are not rated by DBRS.

The ratings are based on the following factors:

(1) The collateral is a diversified pool of $264.2 million first-lien, fixed-rate, owner-occupied, conventional Canadian residential mortgages with a maximum loan-to-value (LTV) of 80% at origination. The weighted-average LTV was 65.7% and the weighted-average credit score of the borrowers was 745 as of the Cut-Off Date.

(2) The experience of MCAP Service Corporation (MSC) in the residential mortgage market, with strong performance history in its other securitization funding programs and servicing capability.

(3) Pass-through structure increases subordination over time.

(4) MSC and the investment-grade-rated Performance Guarantor provide lifetime representations and warranties.

DBRS uses the Canadian RMBS model to estimate default frequency, 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 due to strong asset quality, the financial strength of the Performance Guarantor and proven refinancing liquidity during the financial crisis. Additionally, if the Seller does not offer to renew a performing mortgage that satisfies the Seller’s underwriting criteria (at a rate consistent with the Seller’s then-prevailing posted mortgage rates) and the borrower has not entered into an agreement with any other lender to renew or refinance the mortgage prior to its maturity date, the Master Servicer (including a replacement Master Servicer) will extend the maturity date of the mortgage up to five years (to no later than the Rated Final Distribution Date) at a rate equal to the greater of the existing interest rate 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 the balloon risk, DBRS 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 non-renewal. 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 non-renewal, since such borrowers have been current on their mortgage payments and the timing of defaults is known, DBRS considers scheduled mortgage payments and a certain level of house price appreciation during the mortgage term.

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

The Performance Guarantor, MCAP Commercial LP, is rated BBB (low) with a Stable trend by DBRS as of March 12, 2018, and is the second-largest mortgage finance company in Canada, with $71.1 billion of assets under administration as at July 31, 2018. MSC, as the initial Master Servicer, is a wholly owned subsidiary of the Performance Guarantor.
