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

This transaction is a securitization of a portfolio of seasoned performing and reperforming, primarily first-lien residential mortgages funded by the issuance of the Notes. The Notes are backed by 1,574 loans with a total principal balance of $269,391,458 as of the Cut-Off Date (September 30, 2020).

The portfolio is approximately 167 months seasoned and contains 94.8% modified loans. The modifications happened more than two years ago for 89.5% of the modified loans. Within the pool, 664 mortgages have noninterest-bearing deferred amounts, which equate to approximately 11.4% of the total principal balance. There are no Home Affordable Modification Program (HAMP) and proprietary principal forgiveness amounts included in the deferred amounts.

As of the Cut-Off Date, 98.7% of the loans in the pool are current. Approximately 1.3% is 30 days delinquent under the Mortgage Bankers Association (MBA) delinquency method, and 0.9% is in bankruptcy (all but one bankruptcy loans are performing or 30 days delinquent). Approximately 74.9% of the mortgage loans have been zero times 30 days delinquent (0 x 30) for at least the past 24 months under the MBA delinquency method.

The majority of the pool (99.1%) is exempt from the Consumer Financial Protection Bureau (CFPB) Ability-to-Repay (ATR)/Qualified Mortgage (QM) rules because the loans were originated prior to January 10, 2014, the date on which the rules became applicable. The loans subject to the ATR rules were treated as Non-QM (0.9%).

The Mortgage Loan Sellers, Goldman Sachs Mortgage Company (GSMC; 90.7% of the loans) and MTGLQ Investors, L.P. (MTGLQ; 9.3% of the loans), acquired the mortgage loans in various transactions prior to the Closing Date from various mortgage loan sellers or from an affiliate, GS Mortgage Securities Corp. (the Depositor), which will contribute the loans to the Trust. These loans were originated and previously serviced by various entities through purchases in the secondary market.

As the Sponsor, GSMC, or a majority-owned affiliate, will retain an eligible vertical interest in the transaction consisting of an uncertificated interest (the Retained Interest) in the Trust representing the right to receive at least 5.0% of the amounts collected on the mortgage loans, net of the Trust's fees, expenses, and reimbursements and paid on the Notes (other than the Class R Notes) and the Retained Interest to satisfy the credit risk retention requirements under Section 15G of the Securities Exchange Act of 1934 and the regulations promulgated thereunder.

The loans will be serviced by Select Portfolio Servicing, Inc. (SPS; 100%). The initial aggregate servicing fee for the GSMBS 2020-RPL2 portfolio will be 0.25% per annum.

There will not be any advancing of delinquent principal or interest on any mortgages by the Servicer or any other party to the transaction; however, the Servicer are obligated to make advances in respect to the preservation, inspection, restoration, protection, and repair of a mortgaged property, which includes delinquent tax and insurance payments, the enforcement or judicial proceedings associated with a mortgage loan, and the management and liquidation of properties (to the extent that the Servicer deems such advances recoverable).

When the aggregate pool balance of the mortgage loans is reduced to less than 10% of the Cut-Off Date balance, the Directing Noteholder will have the option to purchase all remaining loans and other property of the Issuer at a specified minimum price. The Directing Noteholder will be a beneficial owner of the most subordinate class of Notes then outstanding (other than the Class C Notes, the Class A-IO-S, the Class R and the Class SA Notes).

As a loss mitigation alternative, the Directing Noteholder may direct the Servicer to sell mortgage loans that are 90 days or more delinquent under the MBA delinquency method to unaffiliated third-party investors in the secondary whole loan market on arms-length terms and at fair market value to maximize proceeds on such loans on a net present value basis.

The transaction employs a sequential-pay cash flow structure. Principal proceeds and excess interest can be used to cover interest shortfalls on the Notes, but such shortfalls on the Class M-2 Notes and more subordinate bonds will not be paid from principal proceeds until the more senior classes are retired. Excess interest can be used to amortize principal of the notes after paying transaction parties' fees, Net WAC shortfalls, and making deposits on to the breach reserve account.

Unlike in prior GSMBS transactions backed by reperforming mortgage loans and rated by DBRS Morningstar, the unpaid interest shortfalls on the Notes do not accrue. When the shortfalls are repaid, the repayment does not include interest on the previously unpaid amounts. The shortfalls are set to accrue at the rates described in the transactions’ documents in the other transactions.

CORONAVIRUS IMPACT
The Coronavirus Disease (COVID-19) 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 continue to rise in the coming months for many residential mortgage-backed securities (RMBS) asset classes, some meaningfully.

Reperforming loan (RPL) is a traditional RMBS asset class that consists of securitizations backed by pools of seasoned performing and reperforming residential home loans. Although borrowers in these pools may have experienced delinquencies in the past, the loans have been largely performing for the past six to 24 months since issuance. Generally, these pools are highly seasoned and contain sizable concentrations of previously modified loans.

As a result of the coronavirus pandemic, DBRS Morningstar expects increased delinquencies, loans on forbearance plans, and a potential near-term decline in the values of the mortgaged properties. Such deteriorations may adversely affects 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: September Update,” published on September 10, 2020, at https://www.dbrsmorningstar.com/research/366542/global-macroeconomic-scenarios-september-update), for the RPL asset class DBRS Morningstar applies more severe market value decline (MVD) assumptions across all rating categories than it previously used. DBRS Morningstar derives such MVD assumptions through a fundamental home price approach based on the forecasted unemployment rates and GDP growth outlined in the moderate scenario. In addition, for pools with loans on forbearance plans, DBRS Morningstar may assume higher loss expectations above and beyond the coronavirus assumptions. Such assumptions translate to higher expected losses on the collateral pool and correspondingly higher credit enhancement.

In the RPL asset class, while the full effect of the coronavirus pandemic may not occur until a few performance cycles later, DBRS Morningstar generally believes that loans which were previously delinquent, recently modified, or have higher updated loan-to-value ratios (LTVs) may be more sensitive to economic hardships resulting from higher unemployment rates and lower incomes. Borrowers with previous delinquencies or recent modifications have exhibited difficulty in fulfilling payment obligations in the past and may revert to spotty payment patterns in the near term. Higher LTV borrowers with lower equity in their properties generally have fewer refinance opportunities and, therefore, slower prepayments.

In addition, for this transaction, as permitted by the Coronavirus Aid, Relief, and Economic Security (CARES) Act, signed into law on March 27, 2020, 211 borrowers (15.4% of the borrowers by balance) either have completed forbearance plans or are on forbearance plans because the borrowers reported financial hardship related to the coronavirus pandemic. These forbearance plans allow temporary payment holidays, followed by repayment once the forbearance period ends. The Servicer, in collaboration with the Sponsor, is generally offering borrowers a three month payment forbearance plan. Beginning in month four, the borrower can repay all or some of the missed mortgage payments at once, deferring the unpaid missed payments, or opt to go on a repayment plan to catch up on missed payments for several, typically six, months. During the repayment period, the borrower needs to make regular payments and additional amounts to catch up on the missed payments. For the Sponsor’s approach to forbearance loans, the Servicer would attempt to contact the borrowers before the expiration of the forbearance period and evaluate the borrowers' capacity to repay the missed amounts. As a result, the Servicer, in collaboration with the Sponsor, may offer an extension of the forbearance period, repayment plan, or other forms of payment relief, such as deferrals of the unpaid P&I amounts or a loan modification, in addition to pursuing other loss mitigation options.

For this transaction, DBRS Morningstar applied additional assumptions to evaluate the impact of potential cash flow disruptions on the rated tranches, stemming from (1) lower P&I collections and (2) no servicing advances on delinquent P&I. These assumptions include:

1. Increased delinquencies for the first 12 months at the AAA (sf) and AA (sf) rating levels,
2. Increased delinquencies for the first nine months at the A (sf) and below rating levels,
3. No voluntary prepayments for the first 12 months for the AAA (sf) and AA (sf) rating levels, and
4. No liquidation recovery for the first 12 months for the AAA (sf) and AA (sf) rating levels.
