OREANDA-NEWS. Fitch Ratings has taken the following rating actions on SLM Student Loan Trust 2013-3:

--Class A-2 affirmed at 'AAAsf'; Outlook Stable;
--Class A-3 at 'AAAsf'; Rating Watch Negative maintained;
--Class B at 'AAsf'; Rating Watch Negative maintained.

KEY RATING DRIVERS

Maturity Risk: The Rating Watch Negative action is based on the heightened risk of the SLM 2013-3 class A-2 and B notes missing their respective legal final maturity dates of April 26, 2027 and Sept. 25, 2043, which would result in an event of default. In an event of such technical default, Fitch would expect ultimate repayment of full principal and interest after the legal final maturity date. Fitch expects to resolve the Negative Watch status once we have revised our FFELP criteria

High Collateral Quality: The trust collateral is comprised of 100% 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.

Sufficient Credit Enhancement: CE is provided by overcollateralization (OC; the excess of trust's asset balance over bond balance) and excess spread, and for the senior notes, subordination of the class B note. As of February 2016, total parity is 101.01% (1.00% CE) and senior parity is 105.18% (4.92% CE). The trust has been releasing cash given the specified overcollateralization amount equal to the greater of 1.00% of the adjusted pool balance and $2,000,000 is maintained.

Adequate Liquidity Support: Liquidity support is provided by a reserve account sized at the greater of 0.25% of the outstanding bond balance and $1,249,991, currently equal to $2,226,244.

Acceptable Servicing Capabilities: Day-to-day servicing is provided by Navient Solutions, Inc. (formerly known as Sallie Mae, Inc.). Fitch believes Navient to be an acceptable servicer of FFELP student loans.

On Nov. 18, 2015, Fitch released its exposure draft which delineates revisions it plans to make to the "Rating U.S. Federal Family Education Loan Program Student Loan ABS Criteria", dated June 23, 2014. Fitch has reviewed this transaction under both the existing and proposed criteria.

RATING SENSITIVITIES
Since the FFELP student loan ABS relies 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, basis risk, and loan extension risk account for the majority of the risk embedded in FFELP student loan transactions. Additional defaults, basis shock beyond Fitch's published stresses, lower than expected payment speed, and other factors 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.
