Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

As previously reported, on June 8, 2015, The Dun & Bradstreet Corporation (the “Company”) entered into an Underwriting Agreement, relating to the offering and sale of $300 million aggregate principal amount of its 4.000% Senior Notes due 2020 (the “Senior Notes”). The Senior Notes have been registered under the Securities Act of 1933, as amended, pursuant to a registration statement on Form S-3 (Registration No. 333-203764) previously filed with the Securities and Exchange Commission.

The closing of the sale of the Senior Notes occurred on June 15, 2015. The net proceeds received by the Company from the sale of the Senior Notes were approximately $296 million, after deducting the underwriting discount and offering expenses. The Company will use the net proceeds from the sale of the Senior Notes for the repayment of borrowings outstanding under its revolving credit facility which expires on July 23, 2019 and for general corporate purposes. The Senior Notes are unsecured and unsubordinated obligations of the Company and rank equally with all of its current and future unsecured and unsubordinated indebtedness, including any borrowings under its senior credit facilities, and senior to all of its future subordinated debt. The Indenture governing the Senior Notes does not prohibit the incurrence of indebtedness by the Company or its subsidiaries.

The Senior Notes will be issued pursuant to an Indenture (the “Indenture”), dated as of March 14, 2006, between the Company and The Bank of New York Mellon (formerly known as The Bank of New York), as supplemented by a First Supplemental Indenture, dated as of December 3, 2012, between the Company and The Bank of New York Mellon, as further supplemented by a Second Supplemental Indenture, dated as of June 15, 2015, between the Company and Wells Fargo Bank, National Association, as trustee. The Second Supplemental Indenture is attached hereto as Exhibit 4.1. The Senior Notes will mature on June 15, 2020. Interest on the Senior Notes is payable semi-annually on June 15 and December 15 of each year, commencing on December 15, 2015. Each interest payment will be made to the persons who are registered holders of the Senior Notes on the immediately preceding June 1 and December 1, respectively.

The foregoing description of the terms of the Senior Notes does not purport to be complete and is qualified in its entirety by reference to the Indenture, filed as Exhibit 4.1 to the Company’s Current Report on Form 8-K dated March 14, 2006, the First Supplemental Indenture, filed as Exhibit 4.1 to the Company’s Current Report on Form 8-K dated December 3, 2012, the Second Supplemental Indenture, attached as Exhibit 4.1 hereto, and the Form of 4.000% Senior Notes due 2020 attached as Exhibit 4.2 hereto.
