PHILADELPHIA--(BUSINESS WIRE)--CIGNA Corporation (NYSE: CI) announced today the determination of the Purchase Price (as defined below) for its previously announced cash tender offer for any and all of its $300 million principal amount of outstanding 6.35% Senior Notes due 2018 (the “Notes”). The tender offer is being made pursuant to an offer to purchase and related letter of transmittal, each dated December 9, 2010, which set forth a more complete description of the terms of the tender offer, including the calculation of the Purchase Price. Holders of the Notes are urged to read the offer to purchase and the related letter of transmittal carefully before making any decisions with respect to the tender offer.

The tender offer will expire at 11:59 P.M., New York City time, on December 15, 2010 (the “Expiration Time”) unless extended or earlier terminated. To be eligible to receive the Purchase Price, holders of the Notes must validly tender and not validly withdraw their Notes prior to the Expiration Time. Tendered Notes may be withdrawn at any time at or before, but not after, the Expiration Time.

CIGNA will pay holders of the Notes that validly tender and do not validly withdraw their Notes prior to the Expiration Time an amount equal to $1,151.74 per $1,000 principal amount of Notes (the “Purchase Price”). In addition to the Purchase Price, CIGNA will also pay accrued and unpaid interest on Notes purchased up to, but not including the settlement date. CIGNA expects the settlement date to be December 16, 2010, the next business date following the Expiration Time.

The Purchase Price was determined by reference to a fixed spread of 45 basis points over the bid-side yield to maturity of the 2.625% U.S. Treasury Notes due November 15, 2020, calculated by the dealer managers at 2:00 p.m., New York City time today, December 15, 2010.
