OREANDA-NEWS. Fitch Ratings has affirmed 16 classes of Credit Suisse USA (CSAIL) Commercial Mortgage Trust Pass-Through Certificates series 2015-C3. A detailed list of rating actions follows at the end of this press release.

KEY RATING DRIVERS

The affirmations of CSAIL 2015-C3 are based on the stable performance of the underlying collateral and no material changes to the pools metrics since issuance. As of the July 2016 distribution date, the pool's aggregate principal balance has been reduced by 0.51% to $1.413 billion from $1.420 billion at issuance. The pool has experienced no realized losses to date, and there are currently no delinquent or specially serviced loans; and no loans are defeased. A minor interest shortfall of $443 is currently affecting class NR. The Fitch debt service coverage ratio (DSCR) and loan to value (LTV) for the pool at issuance were 1.22x and 107.4%, respectively.

Investment-Grade Credit Opinion Loan: The largest loan in the pool, Charles River Plaza North (9%), received a credit opinion of 'BBB-sf' on a stand-alone basis at issuance. The loan is secured by a 354,594 square foot medical office building 100% leased to Massachusetts General Hospital. The lease is guaranteed by Massachusetts General Hospital's parent, Partners Healthcare, which is currently rated 'AA' by Fitch.

High Hotel Exposure: Approximately 23.7% of the pool balance, including three of the top 10 loans (14.5%), consists of hotel properties. The largest hotel backed loan is the Starwood Capital Extended Stay Portfolio (7.4%), the second largest loan in the pool, secured by 50 Extended Stay Hotel properties located across 12 states with a total of 6,106 rooms. The largest single state exposure for the portfolio is Texas with 10 hotels and 1,380 rooms. At issuance the Fitch DSCR and LTV for the loan was 103.4% and 1.48x, respectively.

Limited Amortization: Five of the largest 10 loans, representing 22.3% of the pool, are full-term interest-only loans. In total there are 11 full-term interest-only loans representing 25.2% of the pool. Additionally, there are 42 loans representing 42.6% of the pool that are partial-interest-only.

Pari Passu Debt and Additional Debt: Ten loans, representing 44% of the pool are pari passu: Charles River Plaza North, Starwood Capital Extended Stay Portfolio, The Mall of New Hampshire, Westfield Wheaton, Arizona Grand Resort & Spa, Soho-Tribeca Grand Hotel Portfolio, Westfield Trumbull, WPC Department Store Portfolio, Sterling & Milagro Apartments, and Cape May Hotels. Four loans in the pool (21.2%), Charles River Plaza North, Starwood Capital Extended Stay Portfolio, Arizona Grand Resort & Spa, and Sterling & Milagro Apartments have mezzanine debt held outside the trust.

Collateral Quality: Four properties (13.6%), three of which serve as collateral for top 10 loans (Charles River Plaza North, Soho Grand Hotel, and Tribeca Grand Hotel), were all assigned property quality grades of 'A-' by Fitch at issuance. The fourth property to receive a property quality grade of 'A-' was Congress Hall. The majority of the pool (50.7%) was assigned a property quality grade in the 'B' range.

RATING SENSITIVITIES

The Rating Outlooks remain Stable for all classes due to stable performance of the pool since issuance. Fitch does not foresee positive or negative ratings migration until a material economic or asset level event changes the transaction's portfolio-level metrics.

Additional information on rating sensitivity is available in the report 'CSAIL 2015-C3 (US CMBS)' (July 29, 2015), available at www. fitchratings. com.
