Fitch Ratings affirmed the B long-term issuer default rating on Dun & Bradstreet Corp. and upgraded the company's senior unsecured issue rating to BB-/RR2 from B-/RR5.

The outlook on the issuer default rating is stable.

The ratings reflect the company's performance to date, which has been in-line to better than Fitch's expectations. The ratings also take into account Dun & Bradstreet's deleveraging capacity and leverage improvement, among other things.
