Fitch Ratings has upgraded one class and affirmed three classes of Nomura Asset Securities Corp.'s commercial mortgage pass-through certificates, series 1998-D6. A detailed list of rating actions follows at the end of this press release.

KEY RATING DRIVERS

The upgrade is due to increased credit enhancement, defeasance, and continued paydown. Fitch modeled losses of 9.5% of the remaining pool; expected losses on the original pool balance total 2.6%, including $87.5 million (2.3% of the original pool balance) in realized losses to date. Fitch has designated eight loans (27.1%) as Fitch Loans of Concern; there are no specially serviced loans.

As of the December 2014 distribution date, the pool's aggregate principal balance has been reduced by 97.1% to $108.3 million from $3.72 billion at issuance. Per the servicer reporting, 13 loans (56.1% of the pool) are defeased , the remaining loans are retail (76.7%) and industrial properties (10.7%) located in secondary or tertiary markets with 27.9% exposed to various Cinemark locations and 25.5% exposed to CarMax. Interest shortfalls are currently affecting classes B-4 through B-7H.

RATING SENSITIVITY

Rating Outlooks on classes B-2 and B-3 remain Stable. Class B-2 remains Stable as it is anticipated the class will pay down in full next remittance date. The Rating Outlook on class B-3 is Stable as affirmations are expected due to the likelihood of a full principal recovery. No further upgrades to class B-3 is warranted at this time given that the class has experienced interest shortfalls previously as well as the remote potential for interest shortfalls in the future. According to Fitch's global criteria for rating caps, Fitch will not assign or maintain 'AAAsf' or 'AAsf' ratings for notes that it believes have a high level of vulnerability to interest shortfalls or deferrals, even if permitted under the terms of the documents (for more details please see the full report titled 'Criteria for Rating Caps and Limitations in Global Structured Finance Transactions', dated May 28, 2014, at www.fitchratings.com).

Fitch upgrades the following class as indicated:

--$37.2 million class B-3 to 'Asf' from 'BBBsf'; Outlook Stable.

Fitch affirms the following classes as indicated:

--$286,151 class B-2 at 'Asf'; Outlook Stable;

--$5.6 million class B-5 at 'Dsf'; RE 0%;

--$0 class B-6 at 'Dsf'; RE 0%.

The class A-1A, A-1B, A-1C, A-2, A-3, A-4 and A-5 certificates have paid in full. Fitch does not rate the class B-1, B-4, B-7 and B-7H certificates. Fitch previously withdrew the rating on the interest-only class PS-1 certificates.
