KEY RATING DRIVERS

The affirmations are a result of Fitch's affirmation of the underlying A-5 bond. This transaction is a resecuritization of the ownership interest in a single commercial mortgage-backed certificate, WBCMT series 2007-C30 class A-5. Principal and interest from the underlying commercial mortgage-backed certificate is applied to the A5-A, A5-B certificates in sequential order, while losses are applied in reverse sequential order.

Fitch reviewed the underlying transaction on March 26, 2014 and affirmed class A-5. For more information, see Fitch's commentary in 'Fitch Affirms WBCMT 2007-C30' (March 26, 2013).

RATING SENSITIVITY

The Re-REMIC bonds maintain Stable Outlooks and no rating actions are expected. Credit enhancement for class A5-A is approximately 50% and is provided by the structural support of the A5-B certificate. Credit enhancement for the A5-B certificate is approximately 30% and provided by the structural support of the underlying transaction.

As of the March 2014 remittance, the WBCMT 2007-C30 transaction consists of 229 multifamily and commercial mortgage loans with a principal balance of approximately $6.81 billion. Classes A5-A and A5-B have a total principal balance of $105,145,000 which represents approximately 5.6% of the total balance of the underlying class A5 certificate.

Any extraordinary trust fund expenses incurred by the Trustee up to the first $200,000 will be reimbursed to the Trustee by an affiliate of the depositor. In the event extraordinary trust fund expenses exceed $200,000, they will be paid from available interest.
