Fitch does not rate the interest-only $7,293,000 class X-H, the interest-only $22,895,200 Class X-J, $7,293,000 Class H and $22,895,200 Class J. Since the Nov. 18, 2015 presale publish date, the $160,000,000 class A-3 has decreased in balance from $200,000,000, the $313,000,000 class A-4 has increased in balance from $273,000,000 and the $43,269,000 interest-only class X-D has increased in balance from $25,156,000. Fitch's rating for the interest-only class X-D went from 'BBBsf' to 'BBB-sf'. Additionally, Fitch has withdrawn its rating for the $18,113,000 interest-only class X-E as the certificates are no longer being offered and will not be issued by the issuing entity.

The certificates represent the beneficial ownership interest in the trust, primary assets of which are 57 loans secured by 72 commercial properties having an aggregate principal balance of approximately $805.0 million as of the cutoff date. The loans were contributed to the trust by UBS Real Estate Securities, Inc., Bank of America, National Association, and Morgan Staley Mortgage Capital Holdings LLC.

Fitch reviewed a comprehensive sample of the transaction's collateral, including site inspections on 72.8% of the properties by balance, cash flow analysis of 77.1%, and asset summary reviews on 77.1% of the pool.

KEY RATING DRIVERS

Fitch Leverage Lower than Recent Deals

Fitch Leverage Lower than Recent Deals: The pool's Fitch debt service coverage ratio (DSCR) and loan to value (LTV) are 1.23x and 103.6%, respectively. This represents lower leverage when compared to other Fitch-rated fixed-rated multiborrower transactions for YTD 2015, which average 1.19x and 109.5%, respectively.

Sponsor Concentration: Four of the top 15 loans (18.5% of the pool) are secured by outlet malls that have a related sponsor in Simon Property Group. The parent of that group, Simon Property Group, Inc. is rated 'A'/Stable Outlook. The pool's above average sponsor concentration resulted in a sponsor concentration index (SCI) of 672, which is higher than the YTD 2015 average of 391.

Below Average Amortization: The pool is schedule to amortize by 11.3% of the initial pool balance prior to maturity, which is less than the YTD 2015 average of 12.3%. Eight loans (29.3% of the pool) are full-term interest-only, and 19 loans (37.6% of the pool) are partial-interest only, while the remaining 31 loans are amortizing balloon loans with terms of five to 10 years.

Pool Concentration: The largest 10 loans in the transaction account for 51.0% of the pool by balance. This concentration is slightly higher than the YTD 2015 average concentration of
48.6%. The pool's above-average concentration resulted in a loan concentration index (LCI) of 385, which is higher than the YTD 2015 average of 356

RATING SENSITIVITIES

For this transaction, Fitch's net cash flow (NCF) was 10.5% below the most recent net operating income (NOI; for properties for which a recent NOI was provided, excluding properties that were stabilizing during this period). Unanticipated further declines in property-level NCF could result in higher defaults and loss severities on defaulted loans, and could result in potential rating actions on the certificates.

Fitch evaluated the sensitivity of the ratings assigned to MSCI 2015-UBS8 certificates and found that the transaction displays average sensitivity to further declines in NCF. In a scenario in which NCF declined a further 20% from Fitch's NCF, a downgrade of the senior 'AAAsf' certificates to 'A-sf' could result. In a more severe scenario, in which NCF declined a further 30% from Fitch's NCF, a downgrade of the senior 'AAAsf' certificates to 'BBBsf' could result. The presale report includes a detailed explanation of additional stresses and sensitivities on pages 10 - 11.
