The AAA (sf) ratings on the Certificates reflect 12.00% of credit enhancement provided by subordinated notes in the pool. The AA (sf), A (sf), BBB (sf), BB (sf), and B (high) (sf) ratings reflect 8.35%, 5.75%, 3.60%, 2.00%, and 1.50% of credit enhancement, respectively.

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 investment-property residential mortgages funded by the issuance of the Certificates. The Certificates are backed by 1,049 loans with a total principal balance of $388,315,530 as of the Cut-Off Date (December 1, 2019).

The pool consists of fully amortizing fixed-rate mortgages with original terms to maturity of up to 30 years. Approximately 97.9% of the loans are conforming mortgages made to investors for business or commercial purposes. Consequently, most of the pool (80.4%) are not subject to the Qualified Mortgage and Ability-to-Repay rules. In addition, 31 borrowers have multiple mortgages (66 loans in total) included in the securitized portfolio. About 97.9% of the mortgage loans in the portfolio were eligible for purchase by Fannie Mae or Freddie Mac. Details on the underwriting of loans can be found in the Key Probability of Default Drivers section in the related report.

The originators for the aggregate mortgage pool are JPMorgan Chase Bank, N.A. (JPMCB; rated AA with a Stable trend by DBRS Morningstar; 36.6%); United Shore Financial Services (31.7%); Quicken Loans Inc. (Quicken; 10.6%); Caliber Home Loans, Inc. (5.5%); and various other originators, each comprising less than 5.5% of the mortgage loans. Approximately 3.31% 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.

The mortgage loans will be serviced or subserviced by JPMCB (36.6%); Cenlar FSB (31.7%); NewRez doing business as Shellpoint Mortgage Servicing (SMS; 21.2%); and Quicken (10.6%).

Servicing will be transferred to JPMCB from SMS on the servicing transfer date (February 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 (R&W) 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 precrisis structure.

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

This transaction employs an R&W framework that contains certain weaknesses, such as materiality factors, knowledge qualifiers and sunset provisions that allow for certain R&W to expire within three to six years after the Closing Date. DBRS Morningstar perceives the framework as more limiting than traditional lifetime R&W standards in certain DBRS Morningstar-rated securitizations. To capture the perceived weaknesses in the R&W framework, DBRS Morningstar reduced certain originator scores in this pool. A lower originator score results in increased default and loss assumptions and provides additional cushions for the rated securities.

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