Jan 18 - Fitch Ratings has downgraded three classes and affirmed 10 classes of JP Morgan Chase Commercial Mortgage Securities (JP Morgan) commercial mortgage pass-through certificates series 2003-CIBC6. A detailed list of rating actions follows at the end of this press release. Key Rating Drivers The downgrades reflect an increase in Fitch expected losses across the pool. Fitch modeled losses of 2.8% of the remaining pool; expected losses on the original pool balance total 2.7%, including losses already incurred. The pool has experienced $7.4 million (0.7% of the original pool balance) in realized losses to date. Fitch has designated 19 loans (12.2%) as Fitch Loans of Concern, which includes three specially serviced assets (1.6%). As of the December 2012 distribution date, the pool's aggregate principal balance has been reduced by 25.4% to $793.2 million from $1.06 billion at issuance. Per the servicer reporting, 28 loans (42.4% of the pool) are defeased. Interest shortfalls are currently affecting classes N through NR. The largest contributor to expected losses is secured by a 43,169 square foot (SF) office property in Sacramento, CA (0.7% of the pool). The collateral had transferred to special servicing in April 2012 due to payment default. The property experienced cash flow issues when the buildings largest tenant, Sacramento County (48% of the net rentable area ), had vacated upon its lease expiration in February 2012. The property became REO in November 2012. The servicer is currently working to stabilize the property and has hired a third-party management company to assist with property management and leasing. The next largest contributor to expected losses is secured by a portfolio of three Colorado mobile home parks containing a total of 246 pads (0.5%). The subject loan transferred to special servicing in January 2011 due to payment default. The entire portfolio is currently 51% occupied. One of the parks located in Fort Morgan, CO (80 units; 27% of allocated balance) has been forced to shut down because of water safety issues with remaining occupancy currently at 11%. A receiver is in place, and the servicer is pursuing foreclosure.
