NEW YORK--(BUSINESS WIRE)-- Fitch Ratings expects to rate Discover Financial Service's (Discover) $500 million of senior unsecured notes 'BBB'. The notes will be issued in association with a debt exchange for a like amount of Discover Bank's 8.70% subordinated debt maturing in 2019. The new notes will have a coupon of 3.85% and will mature in November 2022.

Fitch does not consider the transaction to be a coercive debt exchange. Instead, Fitch believes the issuance is an attempt to improve funding costs in the attractive capital markets environment and rationalize the bank's capital position under new Basel III guidelines.
