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 806 loans with a total principal balance of $595,006,943 as of the Cut-Off Date (March 1, 2020).

The pool consists of fully amortizing fixed-rate mortgages with original terms to maturity of up to 30 years. Approximately 35.0% of the loans in the pool are conforming mortgage loans predominantly originated by United Shore Financial Services, LLC (USFS) doing business as United Wholesale Mortgage and Shore Mortgage; LoanDepot.com, LLC (LoanDepot.com); LendUS, LLC (LendUS); Bay Equity, LLC; Guaranteed Rate, Inc.; and Primary Residential Mortgage Inc., which were eligible for purchase by Fannie Mae or Freddie Mac. JPMorgan Chase Bank, N.A. (JPMCB; rated AA with a Stable trend by DBRS Morningstar) generally delegates conforming loan underwriting authority to correspondent lenders and does not subsequently review those 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 aggregate mortgage pool are USFS (75.6%), LoanDepot.com (12.6%), LendUS (1.1%), and various other originators that each comprise less than 2.0% of the mortgage loans. Approximately 4.5% of the loans sold to the mortgage loan seller were acquired by MAXEX Clearing LLC, which purchased such loans from the related originators or an unaffiliated third party that directly or indirectly purchased such loans from the related originators.

Cenlar FSB (87.1%), NewRez doing business as Shellpoint Mortgage Servicing (SMS; 12.5%), and Dovenmuehle Mortgage, Inc. (0.4%) will service or subservice the mortgage loans.

Servicing will be transferred to JPMCB from SMS on the servicing transfer date (June 1, 2020, or a later date) as determined by the issuing entity and JPMCB. For this transaction, the servicing fee payable for mortgage loans serviced by JPMCB and SMS (which will be subsequently serviced by JPMCB) is composed of three separate components: the aggregate base servicing fee, the aggregate delinquent servicing fee, and the aggregate additional servicing fee. These fees vary based on the delinquency status of the related loan and will be paid from interest collections before distribution to the securities.

Nationstar Mortgage LLC will act as the Master Servicer. Citibank, N.A. (rated AA (low) with a Stable trend by DBRS Morningstar) will act as Securities Administrator and Delaware Trustee. JPMCB and Wells Fargo Bank, N.A. (rated AA with a Stable trend by DBRS Morningstar) will act as Custodians. Pentalpha Surveillance LLC will serve as the Representations and Warranties Reviewer.

The Seller intends to retain (directly or through a majority-owned affiliate) a vertical interest in 5% of the principal amount or notional amount of all the senior and subordinate certificates to satisfy the credit risk-retention requirements under Section 15G of the Securities Exchange Act of 1934 and the regulations promulgated thereunder.

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

The ratings reflect transactional strengths that include the following:

-- High-quality credit attributes,
-- Well-qualified borrowers,
-- Satisfactory third-party due diligence review,
-- Structural enhancements,
-- Strong servicer, and
-- 100%-current loans.

The transaction also includes the following challenges:

-- Representations and warranties framework
-- Entities lacking financial strength or securitization history
-- Interim servicer financial capabilities

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