Classes A-X-1, A-X-3, A-X-5 and A-X-7 are interest-only notes. The class balances represent notional amounts.

Classes A-1, A-2, A-4, A-6, A-8, A-9 and A-10 are exchangeable notes. These classes can be exchanged for combinations of exchange notes as specified in the offering documents.

Classes A-5, A-6, A-7 and A-8 are super-senior certificates. These classes benefit from additional protection from the senior support certificates (Classes A-3 and A-4) with respect to loss allocation.

The AAA (sf) rating on the Class A-1 Notes reflects 8.75% of credit enhancement provided by subordinated notes in the pool. The AA (high) (sf), A (sf), BBB (high) (sf), BB (high) (sf) and B (high) (sf) ratings reflect 6.75%, 3.35%, 2.20%, 1.25% and 0.70% of credit enhancement, respectively.

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

GSMBS 2019-PJ3 is a securitization of a portfolio of first-lien, fixed-rate, prime residential mortgages funded by the issuance of the Certificates. The Certificates are backed by 394 loans with a total principal balance of $271,016,060 as of the Cut-Off Date (October 1, 2019).

The originators for the mortgage pool are HomeBridge Financial Services, Inc. (25.3%), loanDepot.com, LLC (19.9%) 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 (8.9%) were sold to MAXEX Clearing LLC and were subsequently acquired by the Mortgage Loan Seller.

NewRez LLC doing business as Shellpoint Mortgage Servicing will service all mortgage loans within the pool. Wells Fargo Bank, N.A. (rated AA with a Stable 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 File Reviewer.

The pool consists of fully amortizing fixed-rate mortgages with original terms to maturity of 30 years and a weighted-average (WA) loan age of four months. Approximately 40.6% 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 59.4% of the pool are traditional, non-agency, prime jumbo mortgage loans.

Compared with prior GSMBS prime securitizations, the GSMBS 2019-PJ3 pool exhibits a similar WA original loan-to-value (LTV) ratio; however, the portfolio contains a more barbelled distribution of LTV ratios with larger concentrations in the higher LTV buckets. For this transaction, 20.2% of the pool have current combined LTV ratios over 80.0% but are generally below 95.0%.

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

The full description of the strengths, challenges and mitigating factors is detailed in the related presale report.
