NEW YORK--(BUSINESS WIRE)--Fitch Ratings has affirmed the senior and subordinate notes for SLM Student Loan Trust 2004-4 at 'AAAsf'. The Rating Outlook remains Stable for all classes.
KEY RATING DRIVERS
High Collateral Quality: The trust collateral consists of 100% of Federal Family Education Loan Program (FFELP) loans. The credit quality of the trust collateral is high, in Fitch's opinion, based on the guarantees provided by the transaction's eligible guarantors and reinsurance provided by the U.S. Department of Education (ED) for at least 97% of principal and accrued interest. Fitch currently maintains a rating of 'AAA'; Outlook Stable for the United States.
Sufficient Credit Enhancement: CE is provided by overcollateralization (OC; the excess of trust's asset balance over bond balance) and excess spread. In addition, the class A notes benefit from subordination from the class B notes. As of June 30, 2015, Fitch's calculated senior and total parity is 285.87% and 108.32%, respectively. In addition, the current pool factor is 5.18%, below the 10% pool factor and as such the transaction is in turbo.
Adequate Liquidity Support: Liquidity support is provided by a reserve account. The reserve is sized equal to the greater of 0.25% of the pool balance, and $2,501,168.
Acceptable Servicing Capabilities: Navient Solutions, Inc. (f.k.a. Sallie Mae, Inc.) is responsible for the day-to-day servicing of the student loans. Fitch believes Navient Solutions to be an acceptable servicer of FFELP student loans.
Since FFELP student loan ABS rely on the U.S. government to reimburse defaults, 'AAAsf' FFELP ABS ratings will likely move in tandem with the 'AAA' U.S. sovereign rating. Aside from the U.S. sovereign rating, defaults and basis risk account for the majority of the risk embedded in FFELP student loan transactions. Additional defaults and basis shock beyond Fitch's published stresses could result in future downgrades. Likewise, a buildup of CE driven by positive excess spread given favorable basis factor conditions could lead to future upgrades.
