OREANDA-NEWS. Fitch Ratings has upgraded one class and affirmed eight classes of GMAC Commercial Mortgage Securities, Inc. commercial mortgage pass-through certificates series 2004-C1 (GMACC 2004-C1). A detailed list of rating actions follows at the end of this press release.

KEY RATING DRIVERS

The upgrade to class F reflects sufficient credit enhancement, due to a sizable subordinate class, and the stable performance of the one remaining loan, which is collateralized by a single tenant retail property. The upgrade also reflects the property's location in a strong retail corridor despite the non-investment grade tenant (Bon-Ton Stores, Inc.). The affirmations of the remaining classes reflect realized losses. To date, $46.3 million (6.4% of the original pool balance) in realized losses have been experienced.

As of the April 2016 distribution date, the pool's aggregate principal balance has been reduced by 98.9% to $8.2 million from $721.4 million at issuance. Interest shortfalls are currently affecting classes G through P.

The one remaining loan is secured by a 230,000 square foot (sf) retail property located in Lombard, IL, which is approximately 20 miles west of Chicago. The subject is 100% leased to Carson Pirie Scott (The Bon-Ton Stores, Inc.) through January 2024, co-terminus with the loan's maturity. The store is part of the Yorktown Center Mall, which is a 1.5 million sf enclosed regional shopping mall that is also anchored by Von Maur and JC Penney. As of year-end (YE) 2014, the servicer reported debt service coverage ratio (DSCR) was 1.37x. The loan is fully amortizing.

RATING SENSITIVITIES

The Rating Outlook on class F remains Stable. Although the credit enhancement will increase with continued paydown, Fitch has concerns with a single event risk. Therefore, a rating cap of 'BBsf' is considered appropriate for this concentrated pool. Fitch does not foresee negative rating migration unless there is material economic change to the remaining loan.
