Other than the specified classes above, DBRS Morningstar does not rate any other classes in this transaction.

This securitization is a portfolio of first-lien fixed-rate prime residential mortgages funded by the issuance of the Certificates. The Certificates are backed by 562 loans with a total principal balance of $542,397,085 as of the Cut-Off Date (December 1, 2020).

The pool consists of fully amortizing fixed-rate mortgages with original terms to maturity of primarily 30 years and a weighted-average loan age of two months. Approximately 1.9% of the pool are conforming, high-balance mortgage loans that were underwritten using an automated underwriting system designated by Fannie Mae or Freddie Mac and were eligible for purchase by such agencies. The remaining 98.1% of the pool are traditional, nonagency, prime jumbo mortgage loans. Details on the underwriting of conforming loans can be found in the Key Probability of Default Drivers section of the related rating report.

The originators for the mortgage pool are CrossCountry Mortgage LLC (47.1%), Movement Mortgage, LLC (19.0%), and various other originators, each comprising less than 15.0% of the mortgage loans. Goldman Sachs Mortgage Company is the Sponsor and the Mortgage Loan Seller of the transaction. For certain originators, the related loans were sold to MAXEX Clearing LLC (6.4%) and were subsequently acquired by the Mortgage Loan Seller.

NewRez LLC, doing business as Shellpoint Mortgage Servicing, will service the mortgage loans in the pool. Wells Fargo Bank, N.A. (rated AA with a Negative trend by DBRS Morningstar) will act as the Master Servicer, Securities Administrator, and Custodian. U.S. Bank Trust National Association will serve as Delaware Trustee. Pentalpha Surveillance LLC will serve as the representations and warranties (R&W) File Reviewer.

The transaction employs a senior-subordinate, shifting-interest cash flow structure that is enhanced from a precrisis structure.

GSMBS 2020-PJ6 is the first prime residential mortgage-backed security (RMBS) transaction issued from the GSMBS shelf PJ series where the coupon rates for certain floating-rate and inverse floating-rate certificates are based on the Secured Overnight Financing Rate. Prior to this deal, GSMBS PJ certificate coupons were either fixed-capped, Libor-based floating-rate, or net WAC.

CORONAVIRUS PANDEMIC IMPACT
The coronavirus pandemic and the resulting isolation measures have caused an economic contraction, leading to sharp increases in unemployment rates and income reductions for many consumers. DBRS Morningstar anticipates that delinquencies may arise in the coming months for many RMBS asset classes, some meaningfully.

The prime mortgage sector is a traditional RMBS asset class that consists of securitizations backed by pools of residential home loans originated to borrowers with prime credit. Generally, these borrowers have decent FICO scores, reasonable equity, and robust income and liquid reserves.

As a result of the coronavirus pandemic, DBRS Morningstar expects increased delinquencies and loans on forbearance plans, slower voluntary prepayment rates, and a potential near-term decline in the values of the mortgaged properties. Such deteriorations may adversely affect borrowers’ ability to make monthly payments, refinance their loans, or sell properties in an amount sufficient to repay the outstanding balance of their loans.

In connection with the economic stress assumed under its moderate scenario (see “Global Macroeconomic Scenarios: December Update,” published on December 2, 2020), for the prime asset class, DBRS Morningstar assumes a combination of higher unemployment rates and more conservative home price assumptions than what DBRS Morningstar previously used. Such assumptions translate to higher expected losses on the collateral pool and correspondingly higher credit enhancement.

In the prime asset class, while the full effect of the coronavirus pandemic may not occur until a few performance cycles later, DBRS Morningstar generally believes that this sector should have low intrinsic credit risk. Within the prime asset class, loans originated to (1) self-employed borrowers or (2) higher loan-to-value ratio (LTV) borrowers may be more sensitive to economic hardships resulting from higher unemployment rates and lower incomes. Self-employed borrowers are potentially exposed to more-volatile income sources, which could lead to reduced cash flow generated from their businesses. Higher LTV borrowers, with lower equity in their properties, generally have fewer refinance opportunities and therefore slower prepayments. In addition, certain pools with elevated geographic concentrations in densely populated urban metropolitan statistical areas may experience additional stress from extended lockdown periods and the slowdown of the economy.

The ratings reflect transactional strengths that include high-quality credit attributes, well-qualified borrowers, satisfactory third-party due-diligence review, structural enhancements, and 100% current loans.

The ratings reflect transactional weaknesses that include their R&W framework, borrowers on forbearance plans, entities lacking financial strength or securitization history, and servicer’s financial capabilities.
