All trends are Stable.

The collateral consists of 49 fixed-rate loans secured by 87 commercial and multifamily properties. The transaction is a sequential-pay pass-through structure. The conduit pool was analyzed to determine the provisional ratings, reflecting the long-term probability of loan default within the term and its liquidity at maturity. Three loans, representing a combined 22.4% of the pool, are shadow-rated investment grade by DBRS Morningstar. When the cut-off loan balances were measured against the DBRS Morningstar Stabilized net cash flow and their respective actual constants, none of the loans had a DBRS Morningstar Term debt service coverage ratio below 1.15 times, a threshold indicative of a higher likelihood of mid-term default. However, the pool includes 15 loans, representing a combined 21.7% of the pool by allocated loan balance, with issuance loan-to-value (LTV) ratios equal to or in excess of 67.1%, a threshold historically indicative of above-average default frequency. The weighted-average (WA) LTV of the pool at issuance was is 60.9%, and the pool is scheduled to amortize down to a WA LTV of 57.8% at maturity.

The transaction includes three loans, representing a combined 22.4% of the total pool balance, that are shadow-rated investment grade by DBRS Morningstar, including Park Tower at Transbay, 230 Park Avenue South and Grand Canal Shoppes. Park Tower at Transbay exhibits credit characteristics consistent with a AAA shadow rating, 230 Park Avenue South exhibits credit characteristics consistent with a BBB (low) shadow rating and Grand Canal Shoppes exhibits credit characteristics consistent with a BBB (high) shadow rating.

Eight loans, including six of the top ten loans, representing 39.9% of the pool, have Strong sponsorship according to DBRS Morningstar. Furthermore, DBRS Morningstar identified only two loans (which, combined, represent just 4.3% of the pool) that have sponsorship and/or loan collateral associated with a voluntary bankruptcy filing, a prior discounted payoff, a loan default, limited net worth and/or liquidity, a historical negative credit event and/or an inadequate commercial real estate experience.

Thirteen loans, representing a combined 35.5% of the pool by allocated loan balance, exhibit issuance LTVs of less than 59.3%, a threshold historically indicative of relatively low-leverage financing and generally associated with below-average default frequency.

No loans were deemed Average (-), Below Average or Poor property quality. Additionally, ten loans, representing 40.1% of the pool balance, exhibited Average (+), Above Average or Excellent property quality. The pool’s largest loan, Park Tower at Transbay, is secured by collateral that DBRS Morningstar deemed to be of Excellent property quality.

Eight loans, representing 34.3% of the aggregate pool balance, are secured by properties that are either fully or partially leased to a single tenant. Four of the top ten loans, including Park Tower at Transbay, 230 Park Avenue South, Domain Tower and 105 East 17th Street, are either fully or partially leased to a single tenant. DBRS Morningstar sampled six of the eight loans secured by single-tenant properties. Additionally, two of the eight loans leased to a single tenant (Park Tower at Transbay and 230 Park Avenue South) are shadow-rated investment grade by DBRS Morningstar. Five of the eight identified properties are leased to single tenants that DBRS Morningstar considers to be investment-grade rated: Park Tower at Transbay, 230 Park Avenue South, Domain Tower, 105 East 17th Street and Chase – Franklin Park, IL.

The pool has a relatively high concentration of loans secured by office properties, as evidenced by nine loans, representing 44.5% of the pool by allocated loan balance, that are secured by such properties. DBRS Morningstar considers office properties to be a riskier property type with a generally above-average historical default frequency. Of the nine loans secured by office properties, two loans, comprising 19.1% of the pool balance, are shadow-rated investment grade by DBRS Morningstar: Park Tower at Transbay and 230 Park Avenue South. Four of the nine identified loans, representing 24.9% of the pool balance, are secured by office properties located in areas with a DBRS Morningstar Market Rank of 8, which is characterized as a highly dense urbanized area, such as New York or San Francisco. These markets benefit from increased liquidity that is driven by consistently strong investor demand. Therefore, such markets tend to benefit from lower default frequencies than less dense suburban, tertiary and rural markets.

Twenty-five loans, representing a combined 71.7% of the pool by allocated loan balance, are structured with full-term IO periods. Expected amortization for the pool is only 4.7%, which is less than recent conduit securitizations. Of the 25 loans structured with full-term IO periods, five loans, representing 28.3% of the pool by allocated loan balance, are located in areas with a DBRS Morningstar Market Rank of 6 or 8. These markets benefit from increased liquidity even during times of economic stress. Three of the 25 identified loans, representing 22.4% of the total pool balance, are shadow-rated investment grade by DBRS Morningstar: Park Tower at Transbay, 230 Park Avenue South and Grand Canal Shoppes.

The pool features a relatively high concentration of loans secured by properties located in less-favorable suburban market areas, as evidenced by 23 loans, representing 31.3% of the pool balance, being secured by properties located in areas with a DBRS Morningstar Market Rank of either 3 or 4. An additional nine loans, totaling 9.8% of the pool balance, are secured by properties located in areas with a DBRS Morningstar Market Rank of either 1 or 2, which are typically considered more rural or tertiary in nature. Ten of the identified loans (which represent 9.2% of the pool balance and are secured by properties located in areas with a DBRS Morningstar Market Rank of 1, 2, 3 or 4) will amortize over the loan term, which can reduce risk over time. The average expected amortization of these loans is 18.9%, which is notably higher than the pool’s total WA expected amortization of 4.7%.

Four loans, representing 24.9% of the total pool balance, are secured by properties located in areas with a DBRS Morningstar Market Rank of 8, which are characterized as urbanized locations.

Classes X-A, X-B, X-D, X-F and X-G are IO certificates that reference a single rated tranche or multiple rated tranches. The IO rating mirrors the lowest-rated applicable reference obligation tranche adjusted upward by one notch if senior in the waterfall.

All ratings are subject to surveillance, which could result in ratings being upgraded, downgraded, placed under review, confirmed or discontinued by DBRS Morningstar.
