Fitch Downgrades 6 Classes of WaMu 2007-SL2

Fitch Ratings downgrades 6 classes of WaMu Commercial Mortgage Securities Trust 2007-SL2, commercial mortgage pass-through certificates. A detailed list of rating actions follows at the end of this release.

The downgrades reflect a greater certainty of expected losses across the pool. Fitch's expected losses for the transaction are 6.35% of the current transaction balance. Fitch has designated 121 loans (23%) as Fitch Loans of Concern, which includes 30 specially serviced assets (5.7%). Given the small balance nature of the loans, Fitch ran additional stress scenarios by increasing cap rate scenarios. Given these scenarios, the Rating Outlook for the investment grade classes was deemed to be Stable.

As of the June 2012 distribution date, the pool's certificate balance has paid down 31.6% to $576 million from $842 million at issuance. There are 504 of the original 664 loans remaining in the transaction. There are currently 30 specially serviced loans (5.7%) in the deal. The average loan size for the transaction is $1.1 million. To date, the transaction has incurred $18.4 million in losses, representing 2.2% of the original transaction.

The largest contributor to Fitch expected loss (0.3%) is secured by a 47,000 square foot retail property located in San Dimas, CA. The property is 100% vacant due to the single tenant vacating at lease end in April 2011. No updates were available on leasing activity.

The second largest contributor to Fitch expected loss (0.89%) is secured by a 169,751 square foot (sf) industrial warehouse property located in Woodland, CA. The asset is currently real-estate owned (REO). The special servicer is currently marketing the asset for sale.

The third largest contributor to Fitch expected loss (0.8%) is secured by a mixed-use property located in Lynbrook, NY. The loan is specially serviced and currently 90 days delinquent. The special servicer is moving to have the loan dismissed from bankruptcy and the bankruptcy hearing is scheduled for July 20, 2012.
