OREANDA-NEWS. Fitch Ratings has upgraded one class and affirmed two classes of Nomura Asset Securities Corp.'s (NASC) 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 expected full repayment of the bond from amortization in the next few remittance periods. The pool has 22 loans remaining, 13 of which (68.5% of the pool) are defeased.

As of the November 2015 distribution date, the pool's aggregate principal balance has been reduced by 98.2% to $69 million from $3.72 billion at issuance. The pool has incurred $92.7 million (2.5% of the original pool balance) in realized losses to date. Fitch has designated two loans (2.5%) as Fitch Loans of Concern; there are no specially serviced loans. Interest shortfalls are currently affecting classes B-4 through B-5.

The remaining nine non-defeased loans do not reflect any historical delinquency, seven of which (28.6% of the pool) are Credit Tenant Lease (CTL) structures with full amortization occurring on either August 2017 or February 2020. 21.1% of the total loans in the pool are exposed to Carmax and are structured as CTL loans. The remaining CTL loans were formerly occupied by Value City but are now leased to various tenants.

RATING SENSITIVITIES
The Rating Outlook of class B-3 remains Stable given the stable performance of the pool and likelihood of imminent repayment.

DUE DILIGENCE USAGE
No third party due diligence was provided or reviewed in relation to this rating action.
