LOUISVILLE, Ky.--(BUSINESS WIRE)--June 5, 2008--Humana Inc. (NYSE: HUM) announced today the completion of its public offerings of $500 million of its 7.20 percent Senior Notes, due June 15, 2018, at 99.891 percent of the principal amount ("2018 Senior Notes") and $250 million of its 8.15 percent Senior Notes, due June 15, 2038, at 99.917 percent of the principal amount ("2038 Senior Notes"). Banc of America Securities LLC and J.P. Morgan Securities Inc. acted as the joint book running managers for both the 2018 Senior Notes and the 2038 Senior Notes (collectively, "Senior Notes Offerings").

The net proceeds from the Senior Notes Offerings will be used to repay outstanding borrowings under the company's unsecured revolving credit agreement ("Credit Agreement"). At May 30, 2008, borrowings outstanding in connection with the Credit Agreement was $750 million.

Contemporaneous with the issuance of the Senior Notes Offerings, the company also entered into interest-rate swap agreements ("Swaps") with major financial institutions which mature concurrent with and have the same critical terms as the Senior Notes Offerings. The Swaps have the effect of converting the fixed interest rates on the Senior Notes Offerings to variable interest rates with the expected result that net interest expense changes will correspond closely to changes in net investment income, thus mitigating any impact upon diluted earnings per common share.
