OREANDA-NEWS. Fitch Ratings has upgraded four and affirmed 15 classes of Credit Suisse Commercial Mortgage Trust commercial mortgage pass-through certificates series 2006-C1 (CSMC 2006-C1). A detailed list of rating actions follows at the end of this press release.

KEY RATING DRIVERS

Upgrades reflect the continued paydown of the transaction and significant percentage of defeased collateral (15.5% of the pool). As of the August 2015 distribution date, the pool's aggregate principal balance has been reduced by 46.1% to \\$1.62 billion from \\$3.01 billion at issuance.

Fitch modeled losses of 7% of the remaining pool; expected losses on the original pool balance total 6.8%, including \\$91.1 million (3% of the original pool balance) in realized losses to date. Fitch has designated 105 as Fitch Loans of Concern (35.4%), which includes 10 specially serviced assets (2.8%). Loan maturities are concentrated over the next year with approximately 40% maturing through year-end and 55% in 2016.

Per the servicer reporting, 25 loans are defeased, including four of the top-15 loans. Interest shortfalls are currently affecting classes J through S.

The largest contributor to expected losses is a specially-serviced loan (0.6% of the pool), which is secured by a single-tenant industrial property located in Butler, Indiana. The loan, which was originally secured by two properties, transferred to special servicing in 2010 after the shared single tenant rejected its leases and vacated the properties as part of a bankruptcy filing. The vacant Michigan property was sold out of receivership in June 2013 with net proceeds applied towards debt obligations. The remaining Indiana property was re-leased to a new single tenant this year. The special servicer is now reportedly pursuing foreclosure and a potential note sale.

The next largest specially serviced asset (0.5%) is secured by a 137,000 square foot office property located in Atlanta, Georgia. The loan transferred in February 2015 due to payment default. Year-end 2014 occupancy was reported at 73%; however, a major tenant (29% of net rentable area [NRA]) was expected to vacate the property at its lease expiration in June 2015. The special servicer is moving forward with foreclosure.

RATING SENSITIVITIES
The Stable Outlooks on classes A through F reflect the increasing credit enhancement and expected continued paydown of the classes. Upgrades were limited due to the significant percentage of Fitch Loans of Concern. Fitch will continue to monitor the changing collateral given the large percentage of the pool maturing in the near future. Ratings on the distressed classes may be subject to further downgrades as losses are realized.
