OREANDA-NEWS. Fitch Ratings rates Chase Issuance Trust, class A(2015-4) as follows:

--\$775,000,000 class A(2015-4) 'AAAsf'; Outlook Stable.


KEY RATING DRIVERS:

Fitch's ratings are based on the underlying receivables pool, available credit enhancement, Chase Bank USA's underwriting and servicing capabilities, and the transaction's legal and cash flow structures, which employ early redemption triggers.

The transaction structure is the same as class A(2015-3), with credit enhancement totaling 14% for class A.

RATING SENSITIVITIES:

Fitch models three different scenarios when evaluating the rating sensitivity compared to expected performance for credit card asset-backed securities transactions: 1) increased defaults, 2) a reduction in monthly payment rate (MPR), and 3) a combination stress of higher defaults and lower MPR.

Increasing defaults alone has no impact on rating migration even in the most severe scenario of a 75% increase in defaults. The rating sensitivity to a reduction in purchase rate is more pronounced with a moderate stress, of a 75% reduction, leading to possible downgrades across all classes. The harshest scenario assumes that an increase in defaults and reduction in MPR occur simultaneously. Similarly, the ratings would only be downgraded under the moderate stress of a 50% increase in defaults and 25% reduction in MPR; however, the severe stress could lead to more drastic downgrades to all classes.

To date, the transactions have exhibited strong performance with all performance metrics within Fitch's initial expectations.
