Morgan Securities LLC, as the representatives of the several underwriters named therein, for the issuance and sale by DCL of $500 million aggregate principal amount of its 4.900% Senior Notes due 2026 (the “Notes”) in a public offering pursuant to a registration statement on Form S-3 (File No. 333-205774) and a related preliminary prospectus supplement and final prospectus supplement filed with the Securities and Exchange Commission. The offering of the Notes is expected to close on March 11, 2016, subject to customary closing conditions.

The Notes were priced at 99.633% of their principal amount.

DCL expects the net proceeds from the offering to be approximately $493.9 million after deducting the underwriting discount and estimated expenses related to the offering.

The Notes are to be issued pursuant to an indenture, dated as of August 19, 2009, and a supplemental indenture (collectively, the “Indenture”) to be entered into among DCL, the Guarantor and U.S. Bank National Association, as trustee. DCL’s obligations under the Notes and the Indenture will be fully and unconditionally guaranteed on an unsecured and unsubordinated basis by the Guarantor.
