The Pricing Agreement incorporated by reference the terms of an Underwriting Agreement (the “Underwriting Agreement”) of the Company dated as of May 1, 2012. The sale of the Senior Notes was registered with the Securities and Exchange Commission in a Registration Statement on Form S-3 (File No. 333-200647) (the “Registration Statement”).

On July 2, 2015, the Company entered into a definitive agreement (as it may be amended, the “merger agreement”) to acquire Humana Inc. (“Humana”) in a merger transaction (the “merger”). The Company intends to use the net proceeds of this offering, together with cash on hand at the Company and Humana, and an approximately $3.2 billion term loan that it expects to borrow at the time the merger is completed, to fund the cash portion of the purchase price of the merger. If the merger is not completed, the Company intends to use the net proceeds of the offering of the Floating Rate Notes, the 2018 Notes and the 2023 Notes for general corporate purposes, including the possible payment of a termination fee under the merger agreement and repayment of a portion of the 2019 Notes, the 2021 Notes, the 2026 Notes, the 2036 Notes and the 2046 Notes.
