RATING SENSITIVITIES

The short-term ratings assigned to the Floater Receipts and Floater Certificates reflects the short-term ratings that Fitch maintains on the banks providing liquidity support and will be adjusted upward or downward in conjunction with the short-term ratings of the banks, and, in some cases, the long-term ratings of the underlying bonds deposited in the trusts. The long-term ratings assigned to the Floater and Residual Receipts and Floater and Residual Certificates are exclusively tied to the creditworthiness of the underlying bonds deposited in the trusts and will reflect all changes to those ratings.
