OREANDA-NEWS. Fitch Ratings has affirmed the senior notes issued by Oklahoma Student Loan Authority Series 2013-1 at 'AAAsf'. The Rating Outlook remains Stable.

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 rates the U.S. 'AAA' with a Stable Outlook.

Sufficient Credit Enhancement: CE is provided by overcollateralization (OC; the excess of trust's asset balance over bond balance) and excess spread. As of December 2015, parity is at 108.37%. Additionally, the trust is in turbo and no cash will be released until all notes have been paid in full.

Adequate Liquidity Support: Liquidity support for note is provided by a reserve account currently at 0.25% of the bond balance.

Acceptable Servicing Capabilities: OSLA is responsible for day-to-day servicing of the trust and Nelnet Servicing LLC provides backup servicing. Fitch believes both are acceptable servicers 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 build-up of CE driven by positive excess spread given favorable basis factor conditions could lead to future upgrades.
