We are not required to establish a sinking fund to retire or repay the Notes.

grade rating by each of the Rating Agencies (as defined in "Description of the Notes")

See "Description of the Notes."

http://www.sec.gov/Archives/edgar/data/1122304/000119312514396012/d811087d424b5.htm[11/4/2014 4:19:05 PM]


424(b)5
Additional Issuances
In the future we may, without the consent of the holders of the Notes, increase the
aggregate principal amount of Notes offered on the same terms and conditions (except
that the public offering price, issue date and first interest payment date may vary), but if
the additional Notes


S-2
Table of Contents
are not fungible with the originally issued Notes for United States federal income tax

purposes, the additional Notes will have a separate CUSIP number.

Use of Proceeds
We intend to use the estimated $740.5 million in net proceeds after deducting
underwriting discounts and commissions and estimated offering expenses from this
offering to redeem all of our outstanding 6.50% Senior Notes due 2018 (the "2018
Notes") and for general corporate purposes. See "Use of Proceeds."

Covenants
The indenture for the Notes limits our ability to consolidate with or merge with or into
any other person (other than in a merger or consolidation in which we are the surviving
person) or sell our property or assets as, or substantially as, an entirety to any person.
This covenant is subject to important qualifications and limitations. See "Description of
Debt Securities--Consolidation, Merger and Sale of Assets" in the accompanying
prospectus.

The indenture for the Notes does not restrict our ability to incur additional indebtedness.
Under the terms of the Notes, the holders of the Notes will not have the benefit of the

covenant in the indenture for the Notes described under "Description of Debt Securities
-- Limitations on Liens on Common Stock of Principal Subsidiaries" in the
accompanying prospectus.

No Cross-Acceleration Event of Default
Under the terms of the Notes, the holders of the Notes will not have the benefit of the
cross-acceleration event of default in the indenture for the Notes described in the fourth
bullet under "Description of Debt Securities--Events of Default and Notice Thereof" in
the accompanying prospectus.

Minimum Denominations
The Notes will be issued and may be transferred only in minimum denominations of
$2,000 and multiples of $1,000 in excess thereof.

Risk Factors
For a discussion of factors you should carefully consider before deciding to purchase
the Notes, see "Forward-Looking Information/Risk Factors" beginning on page 46 of
our 2013 Aetna Annual Report, Financial Report to Shareholders (the "2013 Annual
Report"), incorporated by reference in, and filed with the SEC as an exhibit to, our
Annual Report on Form 10-K for the fiscal year ended December 31, 2013.

Settlement
We expect that delivery of the Notes will be made against payment therefor on or about
November 10, 2014, which will be the fifth business day following the date of pricing of
the Notes (such settlement cycle being herein referred to as "T+5"). Under Rule 15c6-1
under the Securities Exchange Act of 1934, as amended, trades in the secondary market
generally are required to settle in three business days, unless the parties to any such
trade expressly agree


S-3
Table of Contents

424(b)5
otherwise. Accordingly, purchasers who wish to trade Notes on the date of pricing or the
next succeeding business day will be required, by virtue of the fact that the Notes

initially will settle T+5, to specify an alternate settlement cycle at the time of any such
trade to prevent a failed settlement. Purchasers of Notes who wish to trade Notes on the
date of pricing or the next succeeding business day should consult their own advisor.

USE OF PROCEEDS
Our net proceeds from this offering are estimated to be approximately $740.5 million after deducting underwriting discounts and
commissions and estimated offering expenses. We intend to use the net proceeds of this offering to redeem all of our outstanding 2018 Notes and
for general corporate purposes, which may include repayment of commercial paper. As of the date of this prospectus supplement, we had
approximately $495.6 million aggregate principal amount of 2018 Notes outstanding. The 2018 Notes bear a fixed interest coupon of 6.50%. The
2018 Notes are due to mature on September 15, 2018. The aggregate amount of the principal, make-whole premium and accrued interest we expect
to pay in connection with the redemption of the 2018 Notes is estimated to be approximately $591 million.
On November 3, 2014, we issued an irrevocable notice of redemption for all outstanding 2018 Notes, at a make-whole redemption price
calculated as set forth in the 2018 Notes, plus accrued and unpaid interest, with a redemption date set for December 3, 2014.

S-6
Table of Contents
DESCRIPTION OF THE NOTES
The Notes offered by this prospectus supplement consist of a series of "senior debt securities" as described in the accompanying prospectus.
This description supplements the description of the general terms and provisions of the debt securities found in the accompanying prospectus.
References in this description of the Notes to the "Company," the "Issuer," "we," "us" and "our" refer to Aetna Inc.
Capitalized terms used and not otherwise defined below or elsewhere in this prospectus supplement or the accompanying prospectus are used
with the respective meanings given thereto in the Senior Indenture dated as of March 2, 2001 between Aetna Inc. and U.S. Bank National
Association, successor-in-interest to State Street Bank and Trust Company, as Trustee (the "Base Indenture"), as supplemented by the
Supplemental Indenture to be dated as of November 10, 2014 between the Company and the Trustee (the "Supplemental Indenture"). Any
reference to the "Indenture" contained in this prospectus supplement refers to the Base Indenture as supplemented by the Supplemental Indenture
(the "Indenture") unless the context indicates otherwise. Any reference to the "Notes" contained in this prospectus supplement refers to Aetna
Inc.'s 3.500% Senior Notes due November 15, 2024 (the "Notes") unless the context indicates otherwise.
The Indenture, as applicable to the Notes, does not restrict our ability to incur additional indebtedness. In addition, under the terms of the
Notes, the holders of the Notes will not have the benefit of the covenant in the Base Indenture described under "Description of Debt Securities--
Limitations on Liens on Common Stock of Principal Subsidiaries" or the cross-acceleration event of default in the Base Indenture described in the
fourth bullet under "Description of Debt Securities--Events of Default and Notice Thereof," each as described in the accompanying prospectus.
The Indenture contains a limitation on our ability to consolidate or merge with another person or sell our assets; however, this negative
covenant contains important exceptions. See "Description of Debt Securities-- Consolidation, Merger and Sale of Assets" in the accompanying
prospectus.
General
The Notes initially will be limited to $750,000,000 aggregate principal amount. In the future, we may, without the consent of the holders of
the Notes, increase such aggregate principal amount, on the same terms and conditions (except that the public offering price, the issue date and the
first interest payment date may vary). The Notes will be our senior unsecured general obligations and will rank equally with all of our other
existing and future unsecured and unsubordinated indebtedness, and will be structurally subordinated to certain indebtedness assumed in
connection with our May 2013 acquisition of Coventry. As of September 30, 2014, we had approximately $983 million aggregate principal amount
of such indebtedness issued by a subsidiary that would rank effectively ahead of the Notes offered hereby.
Principal of, and premium, if any, and interest on the Notes will be payable, and transfers of the Notes will be registrable, at our office or
agency in the Borough of Manhattan, The City of New York. Transfers of the Notes will also be registrable at any of the other offices or agencies
that we may maintain for that purpose. In addition, payment of interest may be made, at our option, by check mailed to the address of the person
entitled thereto as shown on the security register. The Notes will be issued in minimum denominations of $2,000 and multiples of $1,000 in excess
thereof. No service charge will be made for any registration of transfer or exchange of Notes, except for any tax or other governmental charge that
may be imposed in connection therewith.

424(b)5
Each Note will bear interest from November 10, 2014, payable semi-annually on May 15 and November 15 of each year, commencing
May 15, 2015, to the person in whose name such Note is registered, subject to certain exceptions as provided in the Indenture, at the close of
business on May 1 or November 1, as the case may be, immediately preceding such May 15 or November 15. The Notes will bear interest at a rate
of 3.500% per year

S-7
Table of Contents
and will mature on November 15, 2024. The Notes are not subject to any sinking fund provision. Interest on the Notes will be computed on the
basis of a 360-day year comprised of twelve 30-day months. In any case where any interest payment date is not a Business Day (as defined in the
Indenture), then payment of interest may be made on the next succeeding Business Day without any additional amount being payable in respect of
any delay.
Optional Redemption
At any time prior to August 15, 2024 (three months prior to the maturity date of the Notes), the Notes will be redeemable, in whole or in
part, at a redemption price equal to the greater of:


·
100% of the principal amount of the Notes being redeemed, or

·
the sum of the present value of (i) 100% of the principal amount of the Notes being redeemed and (ii) all required remaining scheduled
interest payments due on the Notes being redeemed, in each case calculated as if the maturity date of the Notes were August 15, 2024

(three months prior to the maturity date of the Notes), discounted to the redemption date on a semi-annual basis (assuming a 360-day
year consisting of twelve 30-day months) at the Treasury Rate (as defined below) plus 20 basis points,
plus, in each case, any interest accrued but not paid to the date of redemption.
At any time on or after August 15, 2024 (three months prior to the maturity date of the Notes), the Notes will be redeemable, in whole or in
part, at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus any interest accrued but not paid to the date of
redemption.
Certain Definitions
The "Treasury Rate" means, with respect to any redemption date for any portion of the Notes,

·
the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published
statistical release designated "H.15(519)" or any successor publication which is published weekly by the Board of Governors of the
Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity

under the caption "Treasury Constant Maturities," for the maturity corresponding to the Comparable Treasury Issue (if no maturity is
within three months before or after the Remaining Life for the Notes, yields for the two published maturities most closely
corresponding to the Comparable Treasury Issue will be determined and the Treasury Rate shall be interpolated or extrapolated from
those yields on a straight line basis, rounding to the nearest month), or

·
if the release referred to in the previous bullet (or any successor release) is not published during the week preceding the calculation date
or does not contain the yields referred to above, the rate per annum equal to the semi-annual equivalent yield to maturity of the

Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal
amount) equal to the Comparable Treasury Price for that redemption date.
The Treasury Rate will be calculated on the third Business Day preceding the redemption date.
"Comparable Treasury Issue" means the United States Treasury security selected by an Independent Investment Banker as having an actual
or interpolated maturity comparable to the remaining term of the Notes to be redeemed, calculated as if the maturity date of the Notes were August
15, 2024 (the "Remaining Life") that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing
new issues of corporate debt securities of comparable maturity to the Remaining Life of the Notes to be redeemed.
"Comparable Treasury Price" means, with respect to any redemption date for any Notes, the average of all Reference Treasury Dealer
Quotations (as defined below) obtained.

S-8

424(b)5
Table of Contents
"Independent Investment Banker" means one of the Reference Treasury Dealers appointed by the Trustee after consultation with us.
"Reference Treasury Dealer" means each of Barclays Capital Inc., Citigroup Global Markets Inc., and J.P. Morgan Securities LLC. If any
Reference Treasury Dealer ceases to be a primary U.S. government securities dealer in the United States (a "Primary Treasury Dealer"), we will
substitute another Primary Treasury Dealer for that dealer.
"Reference Treasury Dealer Quotations" means, with respect to each Reference Treasury Dealer and any redemption date, the average, as
determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal
amount) quoted in writing to the Trustee by that Reference Treasury Dealer at 5:00 p.m. on the third Business Day preceding the redemption date.
Notice; Interest
Notice of any redemption will be mailed at least 15 days but no more than 60 days before the redemption date to each holder of Notes to be
redeemed.
Unless we default in payment of the redemption price, interest will cease to accrue on the Notes or the portions of the Notes called for
redemption on and after the redemption date.
Repurchase Upon a Change of Control
If a Change of Control Triggering Event occurs, unless we have exercised our right to redeem the Notes in full, as described under "Optional
Redemption" above, we will make an offer to each holder of Notes (the "Change of Control Offer") to repurchase any and all (equal to $2,000 or
an integral multiple of $1,000) of such holder's Notes at a repurchase price in cash equal to 101% of the aggregate principal amount of the Notes
to be repurchased plus accrued and unpaid interest, if any, thereon, to the date of repurchase (the "Change of Control Payment"). Within 30 days
following any Change of Control Triggering Event, we will be required to mail a notice to holders of the Notes describing the transaction or
transactions that constitute the Change of Control Triggering Event and offering to repurchase the Notes on the date specified in the notice (the
"Change of Control Payment Date"), which date will be no less than 30 days and no more than 60 days from the date such notice is mailed,
pursuant to the procedures required by the Notes and described in such notice. We must comply with the requirements of Rule 14e-1 under the
Exchange Act, and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with
the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or
regulations conflict with the Change of Control repurchase provisions of the Notes, we will be required to comply with the applicable securities
laws and regulations and will not be deemed to have breached our obligations under the Change of Control repurchase provisions of the Notes by
virtue of such conflicts.
We will not be required to offer to repurchase the Notes upon the occurrence of a Change of Control Triggering Event if a third party makes
such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by us and the third party repurchases
on the applicable date all Notes properly tendered and not withdrawn under its offer; provided that for all purposes of the Notes and the Indenture,
a failure by such third party to comply with the requirements of such offer and to complete such offer shall be treated as a failure by us to comply
with our obligations to offer to purchase the Notes unless we promptly make an offer to repurchase the Notes at 101% of the outstanding principal
amount thereof plus accrued and unpaid interest, if any, thereon, to the date of repurchase, which shall be no later than 30 days after the third
party's scheduled Change of Control Payment Date.
On the Change of Control Payment Date, we will be required, to the extent lawful, to:

·
accept or cause a third party to accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control

Offer;

·
deposit or cause a third party to deposit with the paying agent an amount equal to the Change of Control Payment in respect of each

Note or portion of a Note properly tendered; and

·
deliver or cause to be delivered to the Trustee the Notes properly accepted, together with an officer's certificate stating the aggregate

principal amount of Notes or portions of Notes being purchased.
The definition of Change of Control includes a phrase relating to the direct or indirect sale, transfer, conveyance or other disposition of "all or
substantially all" of the properties or assets of Aetna Inc. and its subsidiaries taken as a whole. Although there is a limited body of case law
interpreting the phrase "substantially all," there is no precise, established definition of the phrase under applicable law. Accordingly, the
applicability of the requirement that we offer to repurchase the Notes as a result of a sale, transfer, conveyance or other disposition of less than all
of the assets of Aetna Inc. and its subsidiaries taken as a whole to another Person (as defined in the Indenture) or group may be uncertain.
For purposes of the foregoing discussion of the applicable Change of Control provisions, the following definitions are applicable:
"Below Investment Grade Rating Event" means the Notes are rated below an Investment Grade Rating by each of the Rating Agencies on any
date from the earlier of (1) the occurrence of a Change of Control and (2) public notice of our intention to effect a Change of Control, in each case
until the end of the 60-day period following the earlier of (1) the occurrence of a Change of Control and (2) public notice of our intention to effect
a Change of Control; provided, however, that if (i) during such 60-day period one or more Rating Agencies has publicly announced that it is
considering the possible downgrade of the Notes, and (ii) a downgrade by each of the Rating Agencies that has made such an announcement would
result in a Below Investment Grade Rating Event, then such 60-day period shall be extended for such time as the rating of the Notes by any such
Rating Agency remains under publicly announced consideration for possible downgrade to a rating below an Investment Grade Rating and a
downgrade by such Rating Agency to a rating below an Investment Grade Rating could cause a Below Investment Grade Rating Event.
Notwithstanding the foregoing, a rating event otherwise arising by virtue of a particular reduction in rating will not be deemed to have occurred in
respect of a particular Change of Control (and thus will not be deemed a Below Investment Grade Rating Event for purposes of the definition of
Change of Control Triggering Event) if the Rating Agencies making the reduction in rating to which this definition would otherwise apply do not
announce or publicly confirm or inform the Trustee in writing at our or the Trustee's request that the reduction was the result, in whole or in part,
of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable
Change of Control has occurred at the time of the rating event).
"Change of Control" means the occurrence of any of the following: (1) direct or indirect sale, transfer, conveyance or other disposition (other
than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the properties or assets of Aetna Inc.
and its subsidiaries taken as a whole to any "person" (as that term is used in Section 13(d)(3) of the Exchange Act) other than to Aetna Inc. or one
of its subsidiaries; (2) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that
any "person" (as that term is used in Section 13(d)(3) of the Exchange Act) other than Aetna Inc. or one of its subsidiaries becomes the beneficial
owner, directly or indirectly, of more than 50% of the then outstanding number of shares of Aetna Inc.'s voting stock; or (3) the first day on which
a majority of the members of Aetna Inc.'s Board of Directors are not Continuing Directors; provided, however, that a transaction will not be
deemed to involve a Change of Control if (A) we become a wholly owned subsidiary of a holding company and (B)(x) the holders of the voting
stock of such holding company immediately following that transaction are substantially the same as the holders of Aetna Inc.'s voting stock
immediately prior to that transaction or (y) immediately following that transaction no "person" (as that term is used in Section 13(d)(3) of the
Exchange Act) is the beneficial owner, directly or indirectly, of more than 50% of the voting stock of such holding company. For purposes of this
definition, "voting stock" means capital stock of any class or kind the holders of which are ordinarily, in the absence of contingencies, entitled to
vote for the election of directors (or persons performing similar functions) of Aetna Inc., even if the right to vote has been suspended by the
happening of such a contingency.
