Upon the occurrence of a change of control, you may require us to repurchase some or all of your notes at 101% of their principal amount, plus accrued and unpaid interest, if any, to, but not including, the date of repurchase.

The notes will be issued only in registered form in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

SUMMARY

The following summary contains certain information about us and the offering of the notes. It does not contain all of the information that may be important to you in making a decision to invest in the notes. We urge you to carefully read the entire prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein, including our financial statements and related notes. You should also read the sections entitled “Risk Factors” and “Forward-Looking Statements” in this prospectus supplement, our Annual Report, our Quarterly Report and any subsequently filed Exchange Act reports for a discussion of important risks that you should consider before investing in the notes.

Unless otherwise indicated or the context otherwise requires, the terms “AES,” “we,” “our,” “us” and “the Company” refer to The AES Corporation, including all of its subsidiaries and affiliates, collectively. The term “The AES Corporation” or “Parent Company” refers only to the parent, a publicly held holding company, The AES Corporation, excluding its subsidiaries and affiliates.

THE AES CORPORATION

We are a diversified power generation and utility company organized into six market-oriented Strategic Business Units (“SBUs”): US (United States), Andes (Chile, Colombia and Argentina), Brazil, MCAC (Mexico, Central America and Caribbean), EMEA (Europe, Middle East and Africa), and Asia. We were incorporated in 1981.

Strategy

Our strategic plan intends to maximize the risk-adjusted value of our portfolio through our efforts to execute upon the following objectives:

· First, we are managing our portfolio of generation and utility businesses to create value through safe, reliable, and sustainable operations and effective cost management.

· Second, we are driving our operating business to manage capital more effectively and to increase the amount of discretionary cash available for deployment into debt repayment, growth investments, shareholder dividends, and share buybacks.

· Third, we are realigning our geographic focus. To this end, we will continue to exit markets where we do not have a competitive advantage or where we are unable to earn a fair risk-adjusted return relative to monetization alternatives. In addition, we will focus our growth investments on platform expansions or opportunities to expand our existing operations.

· Finally, we are working to reduce the cash flow and earnings volatility of our businesses by proactively managing our currency, commodity and political risk exposures, mostly through contractual and regulatory mechanisms, as well as commercial hedging activities. We also will continue to limit our risk by utilizing non-recourse project financing for the majority of our businesses.

Business Lines & Strategic Business Units

Within our six SBUs, as discussed above, we have two lines of business. The first business line is generation, where we own and/or operate power plants to generate and sell power to customers, such as utilities, industrial users, and other intermediaries. The second business line is utilities, where we own and/or operate utilities to generate or purchase, distribute, transmit and sell electricity to end-user customers in the residential, commercial, industrial and governmental sectors within a defined service area. In certain circumstances, our utilities also generate and sell electricity on the wholesale market.

S-1

The following table summarizes our generation business by capacity and facilities and our utilities business by customers, capacity and facilities for each SBU.

(1) 30,251 proportional MW. Proportional MW is equal to gross MW times AES’ equity ownership percentage.

Generation

We currently own and/or operate a generation portfolio of approximately 31,000 MW, excluding the generation capabilities of our integrated utilities. Our generation fleet is diversified by fuel type. As a percentage of installed capacity, coal and natural gas each account for 36% and 35%, respectively, of our generating capacity. Renewables, primarily hydro, wind and solar, represent 25% of our generating capacity and oil, diesel and petroleum coke comprise the rest.

Performance drivers of our generation businesses include types of electricity sales agreements, plant reliability and flexibility, fuel costs, fixed-cost management, sourcing and competition.

Utilities

AES’ 12 utility businesses distribute power to more than 12 million people in six countries. These businesses also include generation capacity totaling approximately 8,500 MW. These businesses have a variety of structures, ranging from integrated utility to pure transmission and distribution businesses.

In general, our utilities sell electricity directly to end-users, such as homes and businesses, and bill customers directly. Key performance drivers for utilities include the regulated rate of return and tariff, seasonality, weather variations, economic activity, reliability of service and competition.

TENDER OFFERS

We have previously announced tender offers (the “Tender Offers”) to purchase for cash up to $800 million aggregate principal amount of four series of our outstanding senior notes, including any and all of our outstanding 7.75% senior notes due 2014 (the “2014 Notes”), of which $500 million are currently

S-2

outstanding; up to $100 million of our outstanding 7.75% senior notes due 2015 (the “2015 Notes”), of which $500 million are currently outstanding; up to $100 million of our outstanding 9.75% senior notes due 2016 (the “2016 Notes”), of which $535 million are currently outstanding; and up to $100 million of our outstanding 8.00% senior notes due 2017 (the “2017 Notes” and, together with the 2014 Notes, the 2015 Notes and the 2016 Notes, the “Outstanding Notes”), of which $1,500 million are currently outstanding. The Tender Offers are scheduled to expire at 11:59 p.m., New York City time, on May 22, 2013, unless extended or earlier terminated. We have reserved the right to increase or decrease the amounts, individually and in the aggregate, of 2015 Notes, 2016 Notes and 2017 Notes purchased in the Tender Offers.

The Tender Offers are subject to the satisfaction of certain conditions. Nothing in this prospectus supplement shall be construed as an offer or solicitation to purchase the Outstanding Notes, which is taking place by means of separate offers to purchase. We intend to use the net proceeds from this offering and the offering of the existing notes, as well as, if necessary, other available funds, to fund the Tender Offers and to pay certain related fees and expenses. If any net proceeds from this offering and the offering of the existing notes remain after completion of the Tender Offers, we intend to use such proceeds to retire certain outstanding indebtedness and for general corporate purposes.

COMPANY INFORMATION

THE OFFERING

The following is a summary of some of the terms of the notes offered hereby. For a more complete description of the terms of the notes, see “Description of the Notes” in this prospectus supplement.

Issuer The AES Corporation.

Notes Offered $250 million aggregate principal amount of 4.875% senior notes due 2023. The notes will be fully fungible with, rank equally with and form a single series with, the $500 million aggregate principal amount of our 4.875% Senior Notes due 2023, issued on April 30, 2013 (the “existing notes”). It is expected that the notes offered hereby and the existing notes will be of the same series and will have the same CUSIP number.

Maturity The notes will mature on May 15, 2023.

Record Date The regular record date for each interest payment date will be the close of business on the 15th calendar day prior to such interest payment date.

Ranking The notes will be our direct, unsecured and unsubordinated obligations and will rank:

· equal in right of payment with all of our other senior unsecured debt;

· effectively junior in right of payment to our secured debt, including our senior credit facilities, to the extent of the value of the assets securing such debt;

· structurally subordinate to the debt and other liabilities (including trade payables) of our subsidiaries; and

· we had approximately $4.6 billion of senior unsecured debt, $802 million of secured debt and $517 million of subordinated debt outstanding;

· our subsidiaries had approximately $28.5 billion of debt and other liabilities, including trade payables, outstanding; and

The indenture under which the notes will be issued contains no restrictions on the amount of additional unsecured indebtedness that we may incur or the amount of

S-6

indebtedness (whether secured or unsecured) that our subsidiaries may incur. The indenture permits us to incur secured debt subject to the covenants described under “Description of the Notes—Certain Covenants of AES—Restrictions on Secured Debt.”

No Guarantees The notes will not be guaranteed by any of our subsidiaries.

Risk Factors Before investing in the notes, you should carefully consider the information discussed under the section entitled “Risk Factors” in this prospectus supplement, in our Annual Report and in our Quarterly Report.

S-8

RISK FACTORS

Investing in the notes involves a high degree of risk. You should carefully consider the risks discussed below, together with the financial and other information contained in or incorporated by reference into this prospectus supplement and the accompanying prospectus, before deciding whether to invest in the notes. In addition to the risk factors discussed below, please read “Risk Factors” and “Forward-Looking Information” in our Annual Report and our Quarterly Report, which are incorporated herein by reference, for more information about important risks that you should consider before investing in the notes.

Risks Related to the Notes

The AES Corporation is a holding company and its ability to make payments on its outstanding indebtedness, including its debt securities, is dependent upon the receipt of funds from its subsidiaries by way of dividends, fees, interest, loans or otherwise.

The AES Corporation is a holding company with no material assets other than the stock of its subsidiaries. All of The AES Corporation’s revenue is generated through its subsidiaries. Accordingly, almost all of The AES Corporation’s cash flow is generated by the operating activities of its subsidiaries. Therefore, The AES Corporation’s ability to make payments on its indebtedness and to fund its other obligations is dependent not only on the ability of its subsidiaries to generate cash, but also on the ability of the subsidiaries to distribute cash to it in the form of dividends, fees, interest, tax sharing payments, loans or otherwise.

However, our subsidiaries face various restrictions in their ability to distribute cash to The AES Corporation. Most of the subsidiaries are obligated, pursuant to loan agreements, indentures or project financing arrangements, to satisfy certain restricted payment covenants or other conditions before they may make distributions to The AES Corporation. In addition, the payment of dividends or the making of loans, advances or other payments to The AES Corporation may be subject to other contractual, legal or regulatory restrictions or may be prohibited altogether. Business performance and local accounting and tax rules may limit the amount of retained earnings that may be distributed to us as a dividend. Subsidiaries in foreign countries may also be prevented from distributing funds to The AES Corporation as a result of foreign governments restricting the repatriation of funds or the conversion of currencies. Any right that The AES Corporation has to receive any assets of any of its subsidiaries upon any liquidation, dissolution, winding up, receivership, reorganization, bankruptcy, insolvency or similar proceedings (and the consequent right of the holders of The AES Corporation’s indebtedness to participate in the distribution of, or to realize proceeds from, those assets) will be structurally subordinated to the claims of any such subsidiary’s creditors (including trade creditors and holders of debt issued by such subsidiary).

The AES Corporation’s subsidiaries are separate and distinct legal entities and, unless they have expressly guaranteed any of The AES Corporation’s indebtedness, have no obligation, contingent or otherwise, to pay any amounts due pursuant to such debt or to make any funds available whether by dividends, fees, loans or other payments. While some of The AES Corporation’s subsidiaries guarantee the Parent Company’s indebtedness under the Parent Company’s senior secured credit facilities, none of its subsidiaries guarantee, or are otherwise obligated with respect to, its outstanding public debt securities, including the notes offered hereby.

The notes will be structurally subordinated to the liabilities of our subsidiaries.

Our subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to pay any amounts due on the notes offered hereby or to make any funds available therefor, whether by dividends, fees, loans or other payments. Any right we have to receive any assets of any of our subsidiaries upon any liquidation, dissolution, winding up, receivership, reorganization, assignment for the benefit of creditors, marshaling of assets and liabilities or any bankruptcy, insolvency or similar proceedings (and the consequent right of the holders of our indebtedness to participate in the distribution of, or to realize proceeds from, those assets) will be structurally subordinated to the claims of any such subsidiary’s creditors (including trade creditors

S-9

and holders of debt issued by such subsidiary). Accordingly, the notes will be structurally subordinated to all liabilities of our subsidiaries, including guarantees by our subsidiaries of our obligations, including our obligations under our senior secured credit facilities. At March 31, 2013, our subsidiaries had approximately $28.5 billion of outstanding liabilities, including debt and trade payables. The indenture governing the notes will not limit the ability of our subsidiaries to incur additional indebtedness, including guaranteeing debt of The AES Corporation.

The notes will be effectively subordinated to our secured debt.

The notes will be unsecured general obligations of The AES Corporation, and therefore will be effectively subordinated to all of the secured debt of The AES Corporation to the extent of the value of the assets securing such debt. As of March 31, 2013, The AES Corporation had a total of approximately $802 million of secured debt outstanding, including amounts outstanding under our senior secured credit facilities, which are secured by, among other things, a lien on certain of our accounts and a pledge of capital stock of most of our directly held subsidiaries. In addition, as of March 31, 2013, we had approximately $797 million of undrawn borrowing capacity under the revolving facility of our senior credit facilities. The indenture governing the notes limits but does not prohibit The AES Corporation from incurring additional secured debt and there are significant exceptions to this covenant. See “Description of the Notes—Certain Covenants of AES—Restrictions on Secured Debt.”

We may not be able to repurchase the notes upon a change of control.

Upon a change of control (as defined under “Description of the Notes—Repurchase of Notes Upon a Change of Control”), we will be required to offer to repurchase all outstanding notes at 101% of their principal amount plus accrued and unpaid interest. The source of funds for any such purchase of the notes will be our available cash or cash generated from our subsidiaries’ operations or other sources, including borrowings, issuance of additional debt, sales of assets or sales of equity. We may not be able to satisfy our obligations to repurchase the notes upon a change of control because we may not have sufficient financial resources to purchase all of the notes that are tendered upon a change of control.

You cannot be sure that an active trading market will develop for these notes, which may hinder your ability to liquidate your investment.

We do not intend to list the notes on any securities exchange. We have been informed by the underwriter that it intends to make a market for the notes after the offering is completed. However, the underwriter may cease its market-making activities at any time. In addition, the liquidity of the trading market in the notes, and the market price quoted for the notes, may be adversely affected by changes in the overall market for fixed income securities and by changes in our financial performance or prospects or in the prospects for companies in our industry generally. In addition, such market-making activity will be subject to limits imposed by the Securities Act of 1933, as amended (the “Securities Act”), and the Exchange Act. As a result, we cannot assure you that an active trading market will develop for the notes. If no active trading market develops, you may not be able to resell your notes at their fair market value or at all.

Credit rating downgrades could adversely affect the trading price of the notes.

The trading price for the notes may be affected by our credit rating. Credit ratings are continually revised. Any downgrade in our credit rating could adversely affect the trading price of the notes or the trading markets for the notes to the extent trading markets for the notes develop.

S-10

Risks Related to Our High Level of Indebtedness

We have a significant amount of debt, a large percentage of which is secured, which could adversely affect our business and our ability to fulfill our obligations.

As of March 31, 2013, we had approximately $21.9 billion of outstanding indebtedness on a consolidated basis, of which approximately $3.6 billion matures in the next 12 months. All outstanding borrowings under The AES Corporation’s senior secured credit facilities and certain other indebtedness are secured by certain of our assets, including the pledge of capital stock of many of The AES Corporation’s directly held subsidiaries. Most of the debt of The AES Corporation’s subsidiaries is secured by substantially all of the assets of those subsidiaries. Since we have such a high level of debt, a substantial portion of cash flow from operations must be used to make payments on this debt. Furthermore, since a significant percentage of our assets are used to secure this debt, this reduces the amount of collateral that is available for future secured debt or credit support and reduces our flexibility in dealing with these secured assets. This high level of indebtedness and related security could have other important consequences to us and our investors, including:

· making it more difficult to satisfy debt service and other obligations at The AES Corporation or individual subsidiaries;

· increasing the likelihood of a downgrade of our debt, which could cause future debt costs or payments to increase under our debt and related hedging instruments and consume an even greater portion of cash flow;

· increasing our vulnerability to general adverse industry conditions and economic conditions, including but not limited to adverse changes in foreign exchange rates and commodity prices;

· reducing the availability of cash flow to fund other corporate purposes and grow our business;

· limiting our flexibility in planning for, or reacting to, changes in our business and the industry;

· placing us at a competitive disadvantage to our competitors that are not as highly leveraged; and

· limiting, along with the financial and other restrictive covenants relating to such indebtedness, among other things, our ability to borrow additional funds as needed or take advantage of business opportunities as they arise, pay cash dividends or repurchase common stock.

The agreements governing our indebtedness, including the indebtedness of our subsidiaries, limit, but do not prohibit the incurrence of additional indebtedness. To the extent we become more leveraged, the risks described above would increase. Further, our actual cash requirements in the future may be greater than expected. Accordingly, our cash flows may not be sufficient to repay at maturity all of the outstanding debt, including the notes, as it becomes due and, in that event, we may not be able to borrow money, sell assets, raise equity or otherwise raise funds on acceptable terms or at all to refinance our debt as it becomes due.

Even though The AES Corporation is a holding company, existing and potential future defaults by subsidiaries or affiliates could adversely affect The AES Corporation.

We attempt to finance our domestic and foreign projects primarily under loan agreements and related documents which, except as noted below, require the loans to be repaid solely from the project’s revenues and provide that the repayment of the loans (and interest thereon) is secured solely by the capital stock, physical assets, contracts and cash flow of that project subsidiary or affiliate. This type of financing is usually referred to as non-recourse debt or “project financing.” In some project financings, The AES Corporation has explicitly agreed to undertake certain limited obligations and contingent liabilities, most of which by their terms will only

S-11

be effective or will be terminated upon the occurrence of future events. These obligations and liabilities take the form of guarantees, indemnities, letter of credit reimbursement agreements and agreements to pay, in certain circumstances, the project lenders or other parties.

As of March 31, 2013, we had approximately $21.9 billion of outstanding indebtedness on a consolidated basis, of which approximately $6.0 billion was recourse debt of The AES Corporation and approximately $15.9 billion was non-recourse debt. In addition, we have outstanding guarantees, indemnities, letters of credit, and other credit support commitments which are further described in our Annual Report and our Quarterly Report, which are incorporated by reference into this prospectus supplement, in Item 7.—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Capital Resources and Liquidity—Parent Company Liquidity and Item 2.—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Capital Resources and Liquidity—Parent Company Liquidity, respectively.

Some of our subsidiaries are currently in default with respect to all or a portion of their outstanding indebtedness. The total debt classified as current in our consolidated balance sheets related to such defaults was $1.3 billion at March 31, 2013. While the lenders under our non-recourse project financings generally do not have direct recourse to The AES Corporation (other than to the extent of any credit support given by The AES Corporation), defaults thereunder can still have important consequences for The AES Corporation, including, without limitation:

· reducing The AES Corporation’s receipt of subsidiary dividends, fees, interest payments, loans and other sources of cash since the project subsidiary will typically be prohibited from distributing cash to The AES Corporation during the pendency of any default;

· under certain circumstances, triggering The AES Corporation’s obligation to make payments under any financial guarantee, letter of credit or other credit support which The AES Corporation has provided to or on behalf of such subsidiary;

· causing The AES Corporation to record a loss in the event the lender forecloses on the assets;

· triggering defaults in The AES Corporation’s outstanding debt and trust preferred securities. For example, The AES Corporation’s senior secured credit facilities and outstanding senior notes include events of default for certain bankruptcy related events involving material subsidiaries. In addition, The AES Corporation’s senior secured credit facilities include certain events of default relating to accelerations of outstanding material debt of material subsidiaries or any subsidiaries that in the aggregate constitute a material subsidiary;

· the loss or impairment of investor confidence in the Company; or

· foreclosure on the assets that are pledged under the non-recourse loans, therefore eliminating any and all potential future benefits derived from those assets.

None of the projects that are currently in default are owned by subsidiaries that, individually or in the aggregate, meet the applicable standard of materiality in The AES Corporation’s senior secured credit facilities or other debt agreements in order for such defaults to trigger an event of default or permit acceleration under such indebtedness. However, as a result of the future mix of distributions, write-down of assets, dispositions and other matters that affect our financial position and results of operations, it is possible that one or more of these subsidiaries, individually or in the aggregate, could fall within the applicable standard of materiality and thereby upon an acceleration of such subsidiary’s debt, trigger an event of default and possible acceleration of the indebtedness under The AES Corporation’s senior secured credit facilities or other indebtedness of The AES Corporation.

USE OF PROCEEDS

The net proceeds from this offering are estimated to be approximately $            , after deducting underwriting discounts and commissions and estimated offering expenses payable by us and excluding accrued interest.

We have previously announced the Tender Offers. We intend to use the net proceeds from this offering and the offering of the existing notes, as well as, if necessary, other available funds, to fund the Tender Offers for any and all of our 2014 Notes, of which $500 million are currently outstanding; up to $100 million of our 2015 Notes, of which $500 million are currently outstanding; up to $100 million of our 2016 Notes, of which $535 million are currently outstanding; and up to $100 million of our 2017 Notes, of which $1,500 million are currently outstanding, and to pay certain related fees and expenses.

S-16

DESCRIPTION OF THE NOTES

The notes will be issued under a senior indenture, dated as of December 8, 1998, between The AES Corporation and Wells Fargo Bank, N.A., as successor to Bank One, National Association (formerly known as The First National Bank of Chicago), as trustee (the “Trustee”), as amended by a ninth supplemental indenture, dated as of April 3, 2003, and a sixteenth supplemental indenture, dated as of April 30, 2013, between The AES Corporation and the Trustee (collectively, the “Indenture”). The following summaries of certain provisions of the Indenture do not purport to be complete and are subject to, and are qualified in their entirety by reference to, all of the provisions of the Indenture, including the definition in the Indenture of certain terms. Wherever particular sections or defined terms of the Indenture are referred to, such sections or defined terms are incorporated into this prospectus supplement by reference. A copy of the Indenture is available for inspection at the office of the Trustee.

As used in this “Description of the Notes”, the terms “AES”, “we”, “us” and “our” mean The AES Corporation, and do not include any of its subsidiaries.

The Indenture does not limit the aggregate principal amount of indebtedness that may be issued thereunder and provides that senior debt securities may be issued thereunder from time to time in one or more series.

General

The notes have the same terms as the $500 million aggregate principal amount of our 4.875% Senior Notes due 2023 issued on April 30, 2013 (the “existing notes”) and, together with such existing notes, make up a single series of notes that are fully fungible with each other. As a result, the outstanding principal amount of the series of notes, after issuance of the notes offered hereby, will be $750 million. This description describes terms of both the existing notes and the notes offered hereby, which together will constitute a single series of notes separate from those other series previously issued under the Indenture.

The notes will be our direct, unsecured and unsubordinated obligations and will rank:

· equal in right of payment with all of our senior unsecured debt;

· effectively junior in right of payment to our secured debt, including our senior credit facilities, to the extent of the value of the assets securing such debt;

· structurally subordinate to the debt and other liabilities (including trade payables) of our subsidiaries; and

· senior in right of payment to our subordinated debt.

As of March 31, 2013:

· we had approximately $4.6 billion of senior unsecured debt, $802 million of secured debt and $517 million of subordinated debt outstanding;

· our subsidiaries had approximately $28.5 billion payable to third parties, including non-recourse debt, trade payables and other liabilities ($15.9 billion of which was non-recourse debt); and

· we had approximately $797 million of undrawn borrowing capacity under the revolving facility of our senior credit facilities.

The indenture under which the notes will be issued contains no restrictions on the amount of additional unsecured indebtedness that we may incur or the amount of indebtedness (whether secured or unsecured) that our subsidiaries may incur. The indenture permits us to incur secured debt subject to the covenants described under “—Certain Covenants of AES—Restrictions on Secured Debt.”

The entire principal amount of the notes will mature and become due and payable, together with any accrued and unpaid interest thereon, on May 15, 2023. The notes will not be guaranteed by any of our subsidiaries. The notes are not subject to any sinking fund provision.

S-17

Interest

The notes shall bear interest at 4.875% per annum from the date of original issuance, payable semiannually on May 15 and November 15 of each year to the person in whose name such note is registered at the close of business on the fifteenth calendar day prior to such payment date. The initial Interest Payment Date is November 15, 2013, and the interest payment made on this payment date will include accrued interest from April 30, 2013. The amount of interest payable will be computed on the basis of a 360-day year of twelve 30-day months. In the event that any date on which interest is payable on the notes is not a Business Day, then payment of the interest payable on such date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay), except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date.

Repurchase of Notes Upon a Change of Control

Upon a Change of Control (as defined below), each holder of the notes shall have the right to require that AES repurchase such holder’s notes at a repurchase price in cash equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to, but not including, the date of repurchase.

Certain of the events constituting a Change of Control under the notes will also constitute an event of default under AES’s senior secured credit facilities and other debt instruments. Due to the highly leveraged nature of AES, there can be no assurance that AES will have sufficient funds to purchase tendered notes upon a Change of Control.

The Change of Control provisions will not necessarily afford protection to holders, including protection against an adverse effect on the value of the notes, in the event that AES or its Subsidiaries incur additional debt, whether through recapitalizations or otherwise. In addition, holders of the Notes may not be entitled to require AES to repurchase their notes in certain circumstances involving a significant change in the composition of AES’s Board of Directors, including in connection with a proxy contest where AES’s Board of Directors does not endorse a dissident slate of directors but approves them as directors. In this regard, a decision of the Delaware Chancery Court (not involving AES or its securities) considered a change of control provision of an indenture governing publicly traded debt securities substantially similar to the change of control event described in clause (iii) of the definition of “Change of Control.” In its decision, the court noted that a board of directors may “approve” a dissident shareholder’s nominees solely for purposes of such an indenture, provided the board of directors determines in good faith that the election of the dissident nominees would not be materially adverse to the interests of the corporation or its stockholders (without taking into consideration the interests of the holders of debt securities in making this determination). See the definition for “Change of Control” below. With respect to a sale of assets, the phrase “all or substantially all,” which appears in the definition of Change of Control, has not gained an established meaning. In interpreting this phrase, courts have made subjective determinations, considering such factors as the value of the assets conveyed and the proportion of an entity’s income derived from such assets. Accordingly, there may be uncertainty as to whether a holder can determine whether a Change of Control has occurred and can exercise any remedies such holder may have upon a Change of Control.

Within 30 days following any Change of Control, AES shall mail a notice to each holder of the notes with a copy to the Trustee stating:

(1) that a Change of Control has occurred and that such holder has the right to require AES to repurchase such holder’s notes at a repurchase price in cash equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to, but not including, the date of repurchase (the “Change of Control Offer”);

(2) the circumstances and relevant facts regarding such Change of Control (including information with respect to pro forma historical income, cash flow and capitalization after giving effect to such Change of Control);

S-18

(3) the repurchase date (which shall be not earlier than 30 days or later than 60 days from the date such notice is mailed) (the “Repurchase Date”);

(4) that any note not tendered will continue to accrue interest;

(5) that any note accepted for payment pursuant to the Change of Control Offer shall cease to accrue interest after the Repurchase Date unless AES defaults in depositing the purchase amount;

(6) that holders electing to have a note purchased pursuant to a Change of Control Offer will be required to surrender the note, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the note completed, to the paying agent at the address specified in the notice prior to the close of business on the Repurchase Date;

(7) that holders will be entitled to withdraw their election if the paying agent receives, not later than the close of business on the third Business Day (or such shorter periods as may be required by applicable law) preceding the Repurchase Date, a telegram, telex, facsimile transmission or letter setting forth the name of the holder, the principal amount of notes the holder delivered for purchase, and a statement that such holder is withdrawing his election to have such notes purchased; and

(8) that holders which elect to have their notes purchased only in part will be issued new notes in a principal amount equal to the unpurchased portion of the notes surrendered.

On the Repurchase Date, AES shall:

· accept for payment notes or portions thereof tendered pursuant to the Change of Control Offer;

· deposit with the Trustee money sufficient to pay the purchase price of all notes or portions thereof so tendered; and

· deliver or cause to be delivered to the Trustee notes so accepted together with an officers’ certificate identifying the notes or portions thereof tendered to AES.

The Trustee shall promptly mail to the holders of the notes so accepted payment in an amount equal to the purchase price, and promptly authenticate and mail to such holders a new note in a principal amount equal to any unpurchased portion of the note surrendered. AES will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Repurchase Date.

AES will comply with all applicable tender offer rules, including without limitation Rule 14e-1 under the Exchange Act, in connection with a Change of Control Offer.

“Board of Directors” means either the Board of Directors of AES or (except for the purposes of clause (iii) of the definition of “Change of Control”) any committee of such Board duly authorized to act under the Indenture.

“Capital Stock” shall mean, with respect to any Person, any and all shares, interests, participations or other equivalents (however designated, whether voting or non-voting) of, or interests in (however designated), the equity of such Person which is outstanding or issued on or after the date of the Indenture, including, without limitation, all Common Stock and Preferred Stock and partnership and joint venture interests of such Person.

“Common Stock” means, with respect to any Person, any and all shares, interests, participations or other equivalents (however designated, whether voting or non-voting) of common stock of such Person which is outstanding or issued on or after the date of the Indenture, including, without limitation, all series and classes of such common stock.

S-19

“Change of Control” shall mean the occurrence of one or more of the following events: (i) any sale, lease, exchange or other transfer (in one transaction or a series of related transactions) of all, or substantially all, of the assets of AES (determined on a consolidated basis) to any Person or group (as that term is used in Section 13(d)(3) of the Exchange Act) of Persons, (ii) a Person or group (as so defined) of Persons shall have become the beneficial owner of more than 50% of the outstanding Voting Stock of AES, or (iii) during any one-year period, individuals who at the beginning of such period constituted the Board of Directors (together with any new director whose election or nomination was approved by a majority of the directors then in office who were either directors at the beginning of such period or who were previously so approved) cease to constitute a majority of the Board of Directors.

“Person” means an individual, a corporation, a partnership, a limited liability company, an association, a trust or any other entity or organization, including a government or political subdivision or an agency or instrumentality thereof.

“Preferred Stock” is defined to mean, with respect to any Person, any and all shares, interests, participations or other equivalents (however designated, whether voting or non-voting) of preferred or preference stock of such Person which is outstanding or issued on or after the date of the Indenture.

“Voting Stock” means, with respect to any Person, Capital Stock of any class or kind ordinarily having the power to vote for the election of directors of such Person or other Persons performing similar functions.

Optional Redemption

On or after May 15, 2018, AES may redeem all or a part of the notes, on any one or more occasions, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest thereon, if any, to, but not including, the applicable redemption date, if redeemed during the twelve-month period beginning on May 15 of the years indicated below:

Redemption Year	Price
2018		102.4375	%
2019		101.6250	%
2020		100.8125	%
2021 and thereafter		100.0000	%

At any time prior to May 15, 2018, AES may also redeem all or a part of the notes at a redemption price equal to 100% of the principal amount of notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, but not including, the redemption date, subject to the rights of holders of record of the notes on the relevant record date to receive interest due on the relevant interest payment date. Calculation of the Applicable Premium is the responsibility of AES, and the Trustee shall have no duty to calculate or verify the calculation of the Applicable Premium.

“Applicable Premium” means, with respect to any note on any redemption date, the excess, if any, of (i) the present value on such redemption date of (A) the redemption price of such note on May 15, 2018 (such redemption price being that set forth in the table above), plus (B) all required remaining scheduled interest payments due on such note through May 15, 2018 (excluding accrued but unpaid interest, if any, to, but not including, the redemption date) computed using a discount rate equal to the Treasury Rate as of such redemption date plus 50 basis points, over (ii) the principal amount of such note.

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to May 15, 2018 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.

S-20

“Comparable Treasury Price” means, with respect to any redemption date:

(a) the average of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) on the third business day preceding such redemption date, as set forth in the most recently published statistical release designated “H.15 (519)” (or any successor release) published 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,” or

(b) if such release (or any successor release) is not published or does not contain such prices on such business day, the average of the Reference Treasury Dealer Quotations for such redemption date.

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by AES.

“Reference Treasury Dealer” means Morgan Stanley & Co. LLC, Barclays Capital Inc. and Citigroup Global Markets Inc.; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), AES shall substitute therefor another Primary Treasury Dealer.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Independent Investment Banker, 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 Independent Investment Banker by such Reference Treasury Dealer at 5:00 p.m. on the third business day preceding such redemption date.

“Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the yield to maturity of the Comparable Treasury Issue, compounded semi-annually, assuming a price for such Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date.

Certain Covenants of AES

Restrictions on Secured Debt. If AES shall incur, issue, assume or guarantee any indebtedness for borrowed money represented by notes, bonds, debentures or other similar evidences of indebtedness, secured by a mortgage, pledge or other lien on any Principal Property (as defined below) or any capital stock or indebtedness held directly by AES of any Subsidiary of AES, AES shall secure the notes equally and ratably with (or prior to) such indebtedness, so long as such indebtedness shall be so secured, unless after giving effect thereto the aggregate amount of all such indebtedness so secured, together with all Attributable Debt (as defined below) in respect of sale and leaseback transactions involving Principal Properties, would not exceed 15% of the Consolidated Net Assets (as defined below) of AES. This restriction will not apply to, and there shall be excluded in computing secured indebtedness for the purpose of such restriction, indebtedness secured by (a) property of any Subsidiary of AES, (b) liens on property of, or on any shares of stock or debt of, any corporation existing at the time such corporation becomes a Subsidiary, (c) liens in favor of AES or any Subsidiary, (d) liens in favor of United States or foreign governmental bodies to secure partial, progress, advance or other payments, (e) liens on property, shares of stock or debt existing at the time of acquisition thereof (including acquisition through merger or consolidation), purchase money mortgages and construction cost mortgages existing at or incurred within 180 days of the time of acquisition thereof, (f) liens existing on the first date on which any notes issued under the Indenture are authenticated by the Trustee, (g) liens under one or more credit facilities for indebtedness in an aggregate principal amount not to exceed $900.0 million at any time outstanding, (h) liens incurred in connection with pollution control, industrial revenue or similar financings, and (i) any extension, renewal or replacement of any debt secured by any liens referred to in the foregoing clauses (a) through (h), inclusive. As of the date of this prospectus supplement, AES does not own or lease any Principal Property.

S-21

“Principal Property” means any building, structure or other facility (together with the land on which it is erected and fixtures comprising a part thereof) used primarily for manufacturing, processing, research, warehousing or distribution owned or leased by AES and having a net book value in excess of 2% of Consolidated Net Assets, other than any such building, structure or other facility or portion thereof which is a pollution control facility financed by state or local governmental obligations or which the principal executive officer, president and principal financial officer of AES determine in good faith is not of material importance to the total business conducted or assets owned by AES and its Subsidiaries as an entirety.

“Consolidated Net Assets” means the aggregate amount of assets (less reserves and other deductible items) after deducting current liabilities, as shown on the consolidated balance sheet of AES and its Subsidiaries contained in the latest annual report to the stockholders of AES and prepared in accordance with generally accepted accounting principles.

“Attributable Debt” means the present value (discounted at the rate of 8.0% per annum compounded monthly) of the obligations for rental payments required to be paid during the remaining term of any lease of more than 12 months.

“Subsidiary” means, with respect to any Person, any corporation, association or other business entity of which a majority of the capital stock or other ownership interests having ordinary voting power to elect a majority of the board of directors or other persons performing similar functions are at the time directly or indirectly owned by such Person.

Restrictions on Sales and Leasebacks. AES may not enter into any sale and leaseback transaction involving any Principal Property, the acquisition or completion of construction and commencement of full operation of which has occurred more than 180 days prior thereto, unless (a) AES could incur a lien on such property under the restrictions described above under “Restrictions on Secured Debt” in an amount equal to the Attributable Debt with respect to the sale and leaseback transaction without equally and ratably securing the notes or (b) AES, within 180 days after the sale or transfer by AES, applies to the retirement of its funded debt (defined as indebtedness for borrowed money having a maturity of, or by its terms extendible or renewable for, a period of more than 12 months after the date of determination of the amount thereof) an amount equal to the greater of (i) the net proceeds of the sale of the Principal Property sold and leased pursuant to such arrangement or (ii) the fair market value of the Principal Property so sold and leased (subject to credits for certain voluntary retirements of funded debt) as determined by the Board of Directors of AES.

Events of Default

With respect to the notes, an Event of Default, as defined in the Indenture, will occur if:

(1) we default in paying principal or premium, if any, on the notes when due, upon acceleration, redemption or otherwise;

(2) we default in paying interest on the notes when it becomes due, and the default continues for a period of 30 days;

(3) we default in performing or breach any other covenant or agreement in the Indenture with respect to the notes and the default or breach continues for a period of 60 consecutive days after written notice by the Trustee or by the holders of 25% or more in aggregate principal amount of all series of notes issued under the Indenture affected thereby;

(4) a court having jurisdiction enters a decree or order for:

· relief in respect of AES or any of our Material Subsidiaries in an involuntary case under any applicable bankruptcy, insolvency, or other similar law now or hereafter in effect,

S-22

· appointment of a receiver, liquidator, assignee, custodian, trustee, sequestrator, or similar official of AES or any of our Material Subsidiaries or for all or substantially all of the property and assets of AES or any of our Material Subsidiaries, or

· the winding up or liquidation of the affairs of AES or any of our Material Subsidiaries and, in each case, such decree or order shall remain unstayed and in effect for a period of 60 consecutive days;

(5) AES or any of its Material Subsidiaries:

· commences a voluntary case under any applicable bankruptcy, insolvency, or other similar law now or hereafter in effect, or consents to the entry of an order for relief in an involuntary case under any such law,

· consents to the appointment of or taking possession by a receiver, liquidator, assignee, custodian, trustee, sequestrator, or similar official of AES or any of its Material Subsidiaries or for all or substantially all of the property and assets of AES or any of its Material Subsidiaries, or

· effects any general assignment for the benefit of creditors; or

(6) an event of default, as defined in any indenture or instrument evidencing or under which AES has as of the date of the Indenture or shall thereafter have outstanding any indebtedness, shall happen and be continuing and either (a) such default results from the failure to pay the principal of such indebtedness in excess of $50 million at final maturity of such indebtedness or (b) as a result of such default the maturity of such indebtedness shall have been accelerated so that the same shall be or become due and payable prior to the date on which the same would otherwise have become due and payable, and such acceleration shall not be rescinded or annulled within 60 days and the principal amount of such indebtedness, together with the principal amount of any other indebtedness of AES in default, or the maturity of which has been accelerated, aggregates $50 million or more; provided that the Trustee shall not be charged with knowledge of any such default unless written notice thereof shall have been given to the Trustee by AES, by the holder or an agent of the holder of any such indebtedness, by the trustee then acting under any indenture or other instrument under which such default shall have occurred, or by the holders of not less than 25% in the aggregate principal amount of the notes at the time outstanding; and provided further that if such default shall be remedied or cured by AES or waived by the holder of such indebtedness, then the Event of Default described under the Indenture by reason thereof shall be deemed likewise to have been remedied, cured or waived without further action on the part of the Trustee, any holder of the notes or any other person.

If an Event of Default with respect to the notes (other than an Event of Default specified in clause (4) or (5) with respect to AES) occurs and continues, then the Trustee or the holders of at least 25% in aggregate principal amount of the notes may, by written notice to us, and the Trustee at the request of at least 25% in aggregate principal amount of the notes will, declare the principal, premium, if any, and accrued interest on the notes to be immediately due and payable. Upon declaration of acceleration, the principal, premium, if any, and accrued interest on the notes shall be immediately due and payable.

If an Event of Default specified in clause (4) or (5) above occurs with respect to AES, the principal, premium, if any, and accrued interest on the notes shall be immediately due and payable, without any declaration or other act on the part of the Trustee or any holder.

If, at any time after the principal of the notes of any series shall have become due and payable and before any judgment for payment shall have been obtained or entered, the holders of at least a majority in principal amount of the notes of all series issued under the Indenture that have been accelerated (voting as a single class), by written notice to us and to the Trustee, may waive all past defaults with respect to the notes of such series and rescind and annul a declaration of acceleration with respect to the notes of such series if:

· all existing Events of Default, other than the nonpayment of the principal, premium, if any, and interest on the notes of such series that have become due solely by that declaration of acceleration, have been cured, waived or otherwise remedied; and

S-23

· AES will have deposited with the Trustee an amount sufficient to pay all matured amounts of interest, principal and premium, if any, which have become due other than by acceleration and all amounts owed to the Trustee.

For information as to the waiver of defaults, see “—Modification and Waiver.”

The holders of at least a majority in principal amount of debt securities of all series issued under the Indenture that are affected (voting as a single class) may direct the time, method, and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to such series of notes. However, the Trustee may refuse to follow any direction that conflicts with law or the Indenture, that may involve the Trustee in personal liability, or that the Trustee determines in good faith may be unduly prejudicial to the rights of holders of debt securities of such series who did not join in giving that direction, and the Trustee may take any other action it deems proper that is not inconsistent with the direction received from holders of outstanding debt securities of such series. A holder of the notes may not pursue any remedy with respect to the Indenture unless:

· the holder gives the Trustee written notice of a continuing Event of Default;

· the holders of at least 25% in principal amount of outstanding notes makes a written request to the Trustee to pursue the remedy;

· the holder or holders offer and, if requested, provide the Trustee indemnity satisfactory to the Trustee against any costs, liability or expense;

· the Trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity; and

· within that 60-day period, the holders of at least a majority in principal amount of the notes do not give the Trustee a direction that is inconsistent with the request.

However, these limitations do not apply to the right of any holder of the notes to receive payment of the principal, premium, if any, or interest on, the notes or to bring suit for the enforcement of any payment, on or after the due date expressed in the notes, which right shall not be impaired or affected without the consent of the holder.

The Indenture requires that certain of our officers certify, on or before a date not more than four months after the end of each fiscal year, that to the best of those officers’ knowledge, we have fulfilled all our obligations under the Indenture. We are also obligated to notify the Trustee of any default or defaults in the performance of any covenants or agreements under the Indenture.

“Material Subsidiary” of any Person means, as of any date, any Subsidiary of which such Person’s proportionate share of such Subsidiary’s total assets (after intercompany eliminations) exceeds 15 percent of the total assets of such Person on a consolidated basis.

“Subsidiary” has the meaning set forth above under “—Certain Covenants of AES—Restrictions on Secured Debt.”

Modification and Waiver

The Indenture may be amended or supplemented without the consent of any holder of the notes to:

· cure ambiguities, defects, or inconsistencies;

· comply with the terms in “Restriction on Mergers, Consolidations and Sales of Assets” described below;

S-24

· comply with any requirements of the Securities and Exchange Commission in connection with the qualification of the Indenture under the Trust Indenture Act of 1939;

· evidence and provide for the acceptance of appointment with respect to the notes by a successor trustee;

· establish the form of notes;

· provide for uncertificated notes and to make all appropriate changes for such purpose; and

· make any change that does not adversely affect the rights of any holder.

Other modifications and amendments of the Indenture may be made with the consent of the holders of not less than a majority in principal amount of the outstanding debt securities of each series affected by the amendment (all such series voting as a separate class). However, no modification or amendment may, without the consent of each holder affected:

· change the stated maturity of the principal of, or any sinking fund obligation or any installment of interest on, the notes;

· reduce the principal amount, premium, if any, or interest on the notes;

· reduce the above-stated percentage of outstanding notes, the consent of whose holders is necessary to modify or amend the Indenture with respect to the notes; or

· reduce the percentage or principal amount of outstanding debt securities of any series, the consent of whose holders is necessary for waiver of compliance with certain provisions of the Indenture or for waiver of certain defaults.

A supplemental indenture which changes or eliminates any covenant or other provision of the Indenture which has expressly been included solely for the benefit of one or more particular series of the debt securities issued under the Indenture, or which modifies the rights of holders of the debt securities of that series with respect to that covenant or provision, shall be deemed not to affect the rights under the Indenture of the holders of the debt securities of any other series issued under the Indenture or of the coupons appertaining to those debt securities. It is not necessary for the consent of the holders under this section of the Indenture to approve the particular form of any proposed amendment, supplement, or waiver, but it is sufficient if the consent approves the substance thereof.

After an amendment, supplement, or waiver under this section of the Indenture becomes effective, we will give to the holders affected thereby a notice briefly describing the amendment, supplement, or waiver. We will mail supplemental indentures to holders upon request. Any failure of us to mail a notice, or any defect therein, will not affect the validity of any supplemental indenture or waiver.

Restriction on Mergers, Consolidations and Sales of Assets

Pursuant to the Indenture, we may not consolidate with, merge with or into, or transfer all or substantially all of our assets to any Person unless:

· AES shall be the continuing Person, or, if AES is not the continuing Person, the Person formed by such consolidation or into which we merged or to which properties and assets of ours are transferred is a solvent corporation organized and existing under the laws of the United States or any State thereof or the District of Columbia and expressly assumes in writing, by supplemental indenture, all our obligations under the notes; and

S-25

· AES delivers to the Trustee (i) an opinion of counsel to the effect that such transaction and such supplemental indenture comply with the Indenture, that all conditions precedent provided for in the Indenture have been complied with and that such supplemental indenture is a valid and binding obligation of AES or the continuing Person, and (ii) an officers’ certificate to the effect that immediately after giving effect to such transaction, no Event of Default has occurred and is continuing.

Reports

We will covenant to deliver to the Trustee, within 15 days after we are required to file the same with the SEC, copies of the annual reports and of the information, documents, and other reports which we may be required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act.

Satisfaction and Discharge

The Indenture will at our request be discharged and will cease to be of further effect (except for, among other matters, certain obligations to register the transfer or exchange of notes, to replace stolen, lost or mutilated notes, to maintain paying agencies and to hold monies for payment in trust) as to all the notes of any series outstanding, when:

· either:

· we have paid or caused to be paid the principal, premium, if any, and interest on all the notes of any series outstanding when due; or

· we have delivered to the Trustee for cancellation all notes of any series theretofore authenticated; or

· (i) all the notes of such series not theretofore delivered to the Trustee for cancellation have become due and payable, or will by their terms become due and payable within one year, or are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption, and (ii) we have irrevocably deposited or caused to be deposited with the Trustee, in trust, funds (whether in cash or United States Government Obligations) in an amount sufficient to pay at maturity or upon redemption all notes of such series not theretofore delivered to the Trustee for cancellation, including principal, premium, if any, and interest due or to become due on or prior to such date of maturity, as the case may be;

· we have paid or caused to be paid all other sums payable under the Indenture by us with respect to notes of such series; and

· upon our request for written acknowledgment of satisfaction and discharge, we have delivered to the Trustee an officers’ certificate and an opinion of counsel stating that all conditions precedent under the Indenture relating to the satisfaction and discharge of the Indenture have been complied with.

Defeasance and Discharge

The Indenture provides that we are deemed to have paid and will be discharged from all obligations in respect of the notes of any series on the 123rd day after the deposit referred to below has been made, and that the provisions of the Indenture will no longer be in effect with respect to the notes of such series (except for, among other matters, certain obligations to register the transfer or exchange of notes, to replace stolen, lost or mutilated notes, to maintain paying agencies and to hold monies for payment in trust) if, among other things:

· we have deposited with the Trustee, in trust, money and/or United States Government Obligations that, through the payment of interest and principal in respect thereof, will provide money in an amount

S-26

sufficient to pay the principal, premium, if any, and accrued interest on the notes of such series, on the date due thereof or earlier redemption (irrevocably provided for under arrangements satisfactory to the Trustee), as the case may be, in accordance with the terms of the Indenture and the notes of such series;

· we have delivered to the Trustee:

· either:

· an opinion of counsel to the effect that holders of such series of notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the exercise of our option under this “Defeasance” provision and will be subject to federal income tax on the same amount and in the same manner and at the same times as would have been the case if the deposit, defeasance, and discharge had not occurred, which opinion of counsel must be based upon a ruling of the Internal Revenue Service (the “IRS”) to the same effect unless there has been a change in applicable federal income tax law or related treasury regulations after the date of the Indenture such that a ruling is no longer required; or

· a ruling directed to the Trustee received from the IRS to the same effect as the aforementioned opinion of counsel; and

· an opinion of counsel to the effect that the creation of the defeasance trust does not violate the Investment Company Act of 1940 and, after the passage of 123 days following the deposit, the trust fund will not be subject to the effect of Section 547 of the U.S. Bankruptcy Code or Section 15 of the New York Debtor and Creditor Law;

· immediately after giving effect to that deposit on a pro forma basis, no Event of Default has occurred and is continuing on the date of the deposit or during the period ending on the 123rd day after the date of the deposit, and the deposit will not result in a breach or violation of, or constitute a default under, any other agreement or instrument to which we are a party or by which we are bound, and

· if at that time the notes of such series are listed on a national securities exchange, we have delivered to the Trustee an opinion of counsel to the effect that such notes will not be delisted as a result of a deposit, defeasance and discharge.

Defeasance of Certain Obligations

The Indenture provides that we may make the same type of deposit referred to above under “—Defeasance and Discharge” and be released from certain restrictive covenants in the notes of any series, including the covenants described above under “—Certain Covenants of AES,” “—Restriction on Mergers, Consolidations and Sales of Assets” and “—Reports”, and clauses (3) and (6) described above under “—Events of Default” shall no longer be deemed Events of Default, if:

· we have deposited with the Trustee, in trust, money and/or United States Government Obligations that, through the payment of interest and principal in respect thereof, will provide money in an amount sufficient to pay the principal, premium, if any, and accrued interest on the notes of such series, on the date due thereof or earlier redemption (irrevocably provided for under arrangements satisfactory to the Trustee), as the case may be, in accordance with the terms of the Indenture and the notes of such series;

· we have delivered to the Trustee:

· an opinion of counsel to the effect that holders of such series of notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the exercise of our option under this “Defeasance” provision and will be subject to federal income tax on the same

S-27

amount and in the same manner and at the same times as would have been the case if the deposit and defeasance had not occurred; and

· an opinion of counsel to the effect that the creation of the defeasance trust does not violate the Investment Company Act of 1940 and, after the passage of 123 days following the deposit, the trust fund will not be subject to the effect of Section 547 of the U.S. Bankruptcy Code or Section 15 of the New York Debtor and Creditor Law;

· immediately after giving effect to that deposit on a pro forma basis, no Event of Default has occurred and is continuing on the date of the deposit or during the period ending on the 123rd day after the date of the deposit, and the deposit will not result in a breach or violation of, or constitute a default under, any other agreement or instrument to which we are a party or by which we are bound, and

· if at that time the notes of such series are listed on a national securities exchange, we have delivered to the Trustee an opinion of counsel to the effect that such notes will not be delisted as a result of a deposit, defeasance and discharge.

Book-Entry, Delivery and Form

Except as set forth below, the notes will be issued in registered, global form in minimum denominations of $2,000 and integral multiples of $1,000 in excess of $2,000.

The notes initially will be represented by one or more notes in registered, global form without interest coupons (collectively, the “Global Notes”). The Global Notes will be deposited upon issuance with the Trustee as custodian for DTC, and registered in the name of DTC or its nominee, in each case for credit to an account of a direct or indirect participant in DTC as described below.

Except as set forth below, the Global Notes may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee. Beneficial interests in the Global Notes may not be exchanged for notes in certificated form (“Certificated Notes”) except in the limited circumstances described below. See “—Exchange of Global Notes for Certificated Notes” below.

In addition, transfers of beneficial interests in the Global Notes will be subject to the applicable rules and procedures of DTC and its direct or indirect participants (including, if applicable, those of Euroclear and Clearstream), which may change from time to time.

Depositary Procedures

The following description of the operations of DTC, Euroclear and Clearstream are provided solely as a matter of convenience. These operations and procedures are solely within the control of the respective settlement systems and are subject to changes by them. We and the Trustee take no responsibility for these operations and procedures and urge you to contact the system or their participants directly to discuss these matters.

DTC has advised us that it is a limited-purpose trust company created to hold securities for its participating organizations (collectively, the “Participants”) and to facilitate the clearance and settlement of transactions in those securities between Participants through electronic book-entry changes in accounts of its Participants. The Participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. Access to DTC’s system is also available to other entities such as banks, brokers, dealers and trust companies that maintain a custodial relationship with a Participant, either directly or indirectly (collectively, the “Indirect Participants”).

Persons who are not Participants may beneficially own securities held by or on behalf of DTC only through Participants or the Indirect Participants. The ownership of interests in, and transfers of ownership interests in,

S-28

each security held by or on behalf of DTC are recorded on the records of the Participants and the Indirect Participants.

DTC has also advised us that, pursuant to procedures established by it, ownership of interests in the Global Notes will be shown on, and the transfer of ownership of these interests will be effected only through, records maintained by DTC (with respect to the Participants) or by the Participants and the Indirect Participants (with respect to other owners of beneficial interest in the Global Notes).

Investors in the Global Notes who are Participants in DTC’s system may hold their interests therein directly through DTC. Investors in the Global Notes that are not Participants may hold their interests indirectly through organizations (including Euroclear and Clearstream) which are Participants in such system. Euroclear and Clearstream will hold interests in the Global Notes on behalf of their participants through customers’ securities accounts in their respective names on the books of their respective depositaries. All interests in a Global Note, including those held through Euroclear or Clearstream, may be subject to the procedures and requirements of DTC. Those interests held through Euroclear or Clearstream may also be subject to the procedures and requirements of such systems. The laws of some states require that certain persons take physical delivery in definitive form of securities they own. Consequently, the ability to transfer beneficial interests in a Global Note to such persons will be limited to that extent. Because DTC can act only on behalf of Participants, which in turn act on behalf of Indirect Participants, the ability of a person having beneficial interests in a Global Note to pledge such interests to persons that do not participate in the DTC system, or otherwise take actions in respect of such interests, may be affected by the lack of a physical certificate evidencing such interests.

Except as described below, owners of interests in the Global Notes will not have notes registered in their name, will not receive physical delivery of notes in certificated form and will not be considered the registered owners or “holders” thereof under the Indenture for any purpose.

Payments in respect of the principal of, and interest (including additional interest) and premium, if any, on a Global Note registered in the name of DTC or its nominee will be payable to DTC in its capacity as the registered holder under the Indenture. Under the terms of the Indenture, we and the Trustee will treat the persons in whose names the notes, including the Global Notes, are registered as the owners of the notes for the purpose of receiving payments and all other purposes. Consequently, neither we, the Trustee nor any agent of us or the Trustee has or will have any responsibility or liability for:

(1) any aspect of DTC’s records or any Participant’s or Indirect Participant’s records relating to payments made on account of beneficial ownership interests in the Global Notes or for maintaining, supervising or reviewing any of DTC’s records or any Participant’s or Indirect Participant’s records relating to the beneficial ownership interests in the Global Notes; or

(2) any other matter relating to the actions or practices of DTC or any of its Participants or Indirect Participants.

DTC has advised us that its current practice, upon receipt of any payment in respect of securities such as the notes (including principal and interest), is to credit the accounts of the relevant Participants with the payment on the payment date unless DTC has reason to believe it will not receive payment on such payment date. Each relevant Participant is credited with an amount proportionate to its beneficial ownership of an interest in the principal amount of the relevant security as shown on the records of DTC. Payments by the Participants and the Indirect Participants to the beneficial owners of notes will be governed by standing instructions and customary practices and will be the responsibility of the Participants or the Indirect Participants and will not be the responsibility of DTC, the Trustee or us. Neither we nor the Trustee will be liable for any delay by DTC or any of its Participants in identifying the beneficial owners of the notes, and we and the Trustee may conclusively rely on and will be protected in relying on instructions from DTC or its nominee for all purposes.

Transfers between Participants in DTC will be effected in accordance with DTC’s procedures, and will be settled in same-day funds, and transfers between Participants in Euroclear and Clearstream will be effected in accordance with their respective rules and operating procedures.

S-29

Cross-market transfers between the Participants in DTC, on the one hand, and Euroclear or Clearstream participants, on the other hand, will be effected through DTC in accordance with DTC’s rules on behalf of Euroclear or Clearstream, as the case may be, by its respective depositary; however, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counter-party in such system in accordance with the rules and procedures and within the established deadlines (Brussels time) of such system. Euroclear or Clearstream, as the case may be, will, if the transaction meets the settlement requirements, deliver instructions to its respective depositary to take action to effect final settlement on its behalf by delivering or receiving interests in the relevant Global Note in DTC, and making or receiving payment in accordance with normal procedures for same day fund settlement applicable to DTC. Euroclear participants and Clearstream participants may not deliver instructions directly to the depositaries for Euroclear or Clearstream.

DTC has advised us that it will take any action permitted to be taken by a holder of notes only at the direction of one or more Participants to whose account DTC has credited the interests in the Global Notes and only in respect of such portion of the aggregate principal amount of the notes as to which such Participant or Participants has or have given such direction. However, if there is an Event of Default under the notes, DTC reserves the right to exchange the Global Notes for legended notes in certificated form, and to distribute such notes to its Participants.

Although DTC, Euroclear and Clearstream have agreed to the foregoing procedures to facilitate transfers of interests in the Global Notes among participants in DTC, Euroclear and Clearstream, they are under no obligation to perform or to continue to perform such procedures, and may discontinue such procedures at any time. Neither we nor the Trustee nor any of our respective agents will have any responsibility for the performance by DTC, Euroclear or Clearstream or their respective participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

Exchange of Global Notes for Certificated Notes

A Global Note is exchangeable for Certificated Notes if:

(1) DTC (a) notifies us that it is unwilling or unable to continue as depositary for the Global Notes, and we fail to appoint a successor depositary, or (b) has ceased to be a clearing agency registered under the Exchange Act;

(2) at our option, we notify the Trustee in writing that we elect to cause the issuance of the Certificated Notes; or

(3) there has occurred and is continuing a Default or Event of Default with respect to the notes and DTC requests such exchange.

In addition, beneficial interests in a Global Note may be exchanged for Certificated Notes upon prior written notice given to the Trustee by or on behalf of DTC in accordance with the Indenture. In all cases, Certificated Notes delivered in exchange for any Global Note or beneficial interests in Global Notes will be registered in the names, and issued in any approved denominations, requested by or on behalf of the depositary (in accordance with its customary procedures).

Same Day Settlement and Payment

We will make payments in respect of the notes represented by the Global Notes (including principal, premium, if any, and interest) through the paying agent by wire transfer of immediately available funds to the accounts specified by the Global Note holder. We will make all payments of principal, interest and premium, if any, with respect to Certificated Notes through the paying agent by wire transfer of immediately available funds to the accounts specified by the holders thereof or, if no account is specified, by mailing a check to that holder’s registered address. The notes represented by the Global Notes are expected to trade in DTC’s Same Day Funds

S-30

Settlement System, and any permitted secondary market trading activity in the notes will, therefore, be required by DTC to be settled in immediately available funds. We expect that secondary trading in any Certificated Notes will also be settled in immediately available funds.

Because of time zone differences, the securities account of a Euroclear or Clearstream participant purchasing an interest in a Global Note from a Participant in DTC will be credited, and any crediting of this type will be reported to the relevant Euroclear or Clearstream participant, during the securities settlement processing day (which must be a business day for Euroclear and Clearstream) immediately following the settlement date of DTC. DTC has advised us that cash received in Euroclear or Clearstream as a result of sales of interests in a Global Note by or through a Euroclear or Clearstream participant to a Participant in DTC will be received with value on the settlement date of DTC but will be available in the relevant Euroclear or Clearstream cash account only as of the business day for Euroclear or Clearstream following DTC’s settlement date.

Governing Law

The Indenture and notes will be governed by and construed in accordance with the laws of the State of New York.

Information Concerning the Trustee

AES and its subsidiaries may maintain deposit accounts and conduct other banking transactions with the Trustee in the ordinary course of business.

S-31

U.S. FEDERAL INCOME TAX CONSEQUENCES

The following is a description of the material U.S. federal income tax consequences of ownership and disposition of the notes. This discussion applies only to notes that meet both of the following conditions:

· they are purchased by initial holders who purchase notes in this offering at the price to investors indicated on the cover of this prospectus supplement; and

· they are held as capital assets.

This discussion does not describe all of the tax consequences that may be relevant to holders in light of their particular circumstances or to holders subject to special rules, such as:

· certain financial institutions (such as banks);

· tax-exempt organizations;

· insurance companies;

· dealers or traders in securities or commodities;

· persons holding notes as part of an integrated transaction;

· U.S. Holders (as defined below) whose functional currency is not the U.S. dollar;

· partnerships or other entities or arrangements classified as partnerships for U.S. federal income tax purposes;

· U.S. expatriates; or

· persons subject to the alternative minimum tax.

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds notes, the U.S. federal income tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. Partners of partnerships holding notes are urged to consult their tax advisors as to their particular U.S. federal income tax consequences of holding and disposing of the notes.

This summary is based on the U.S. Internal Revenue Code of 1986, as amended (the “Code”), administrative pronouncements, judicial decisions and final, temporary and proposed Treasury Regulations, changes to any of which after the date of this prospectus supplement may affect the tax consequences described herein, possibly on a retroactive basis. Persons considering the purchase of notes are urged to consult their tax advisors with regard to the application of the U.S. federal income tax laws to their particular situations as well as any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction or any other U.S. federal tax laws, such as estate and gift tax laws or the recently enacted Medicare tax on certain investment income.

For U.S. federal income tax purposes, the notes offered hereby will be treated as part of the same “issue” as the existing notes, and therefore will be fungible with the existing notes for U.S. federal income tax purposes.

Tax Consequences to U.S. Holders

As used in this section, the term “U.S. Holder” means a beneficial owner of a note that is for U.S. federal income tax purposes:

· an individual who is a citizen or resident of the United States;

S-32

· a corporation, or other entity taxable as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the United States, any state thereof or the District of Columbia; or

· an estate or trust the income of which is subject to U.S. federal income taxation regardless of its source.

Potential Contingent Payment Debt Treatment

Under certain circumstances, the Company may pay holders of notes amounts in excess of the stated interest and principal payable on the notes or may pay amounts prior to the normally scheduled payment dates. In particular, upon the occurrence of a Change of Control, the Company would generally be required to repurchase the notes at 101% of their principal amount plus accrued and unpaid interest, as described under “Description of Notes—Repurchase of Notes Upon a Change of Control.” The Company intends to take the position that the possibility that it may be required to make these payments does not result in the notes being treated as contingent payment debt instruments under the applicable Treasury Regulations. The Company’s position is not binding on the Internal Revenue Service (the “IRS”). If the IRS successfully takes a contrary position, U.S. Holders would be required to treat any gain recognized on the sale or other disposition of the notes as ordinary income rather than as capital gain. In addition, U.S. Holders would be required to accrue interest income on a constant yield basis at an assumed yield determined at the time of issuance of the notes, with adjustments to such accruals when any contingent payments are made that differ from the payments calculated based on the assumed yield. U.S. Holders should consult their tax advisors regarding the tax consequences of the notes being treated as contingent payment debt instruments. The remainder of this discussion assumes that the notes are not treated as contingent payment debt instruments.

Payments of Interest

The notes are expected to be, and the remainder of this discussion assumes that the Notes will be, issued without original issue discount for U.S. federal income tax purposes. Interest paid on a note will be taxable to a U.S. Holder as ordinary interest income at the time it accrues or is received in accordance with the holder’s method of accounting for U.S. federal income tax purposes.

Pre-Acquisition Accrued Interest

A portion of the price paid for a note may be allocable to interest that accrued prior to the date the note is purchased (the “pre-acquisition accrued interest”). On the first interest payment date, a portion of the interest received in an amount equal to the pre-acquisition accrued interest should be treated as a return of the pre-acquisition accrued interest and not as a payment of interest on the note. Amounts treated as a return of pre-acquisition accrued interest should not be taxable when received.

Amortizable Bond Premium

Subject to the discussion below, if a U.S. Holder purchases a note for an amount that is greater than its principal amount, the U.S. Holder will be considered to have purchased the note with amortizable bond premium. In general, the amortizable bond premium with respect to any note is the excess of the purchase price (disregarding the amount attributable to pre-acquisition accrued interest) over the principal amount, and a U.S. Holder may elect to amortize this bond premium, using a constant-yield method, over the remaining term of the note. A U.S. Holder generally may use the amortizable bond premium allocable to an accrual period to offset stated interest otherwise required to be included in income with respect to the note in that accrual period. An election to amortize bond premium applies to all taxable debt obligations then owned or thereafter acquired and may be revoked only with the consent of the IRS. However, because the notes may be redeemed at an amount in excess of the principal amount under certain circumstances, a U.S. Holder’s ability to amortize bond premium may be limited or deferred. A U.S. Holder should consult its tax advisor regulating the calculation of amortizable bond premium.

S-33

A U.S. Holder may also make an election to include in income all interest that accrues on a note in accordance with a constant-yield method based on the compounding of interest. If a U.S. Holder makes a constant-yield election for a note with amortizable bond premium, that election will result in a deemed election to amortize bond premium for all of the U.S. Holder’s debt instruments with amortizable bond premium, and may be revoked only with the permission of the IRS with respect to debt instruments acquired after revocation. Except as discussed in this paragraph, this discussion assumes that a U.S. Holder does not make the election to accrue all interest on a constant-yield method.

Sale, Exchange or Retirement

Upon the sale, exchange, retirement or other taxable disposition (including a redemption) of a note, a U.S. Holder will generally recognize taxable gain or loss equal to the difference between the amount realized on the sale, exchange, retirement or other taxable disposition and the holder’s adjusted tax basis in the note. A U.S. Holder’s adjusted tax basis in a note generally will equal the cost of the note reduced by any pre-acquisition accrued interest and any amortized bond premium. For these purposes, the amount realized does not include any amount attributable to accrued interest not previously included in income. Amounts attributable to accrued interest not previously included in income are treated as interest as described under “Payments of Interest” above.

Gain or loss realized on the sale, exchange, retirement or other taxable disposition of a note will generally be capital gain or loss and will be long-term capital gain or loss if at the time of sale, exchange, retirement or other taxable disposition the note has been held for more than one year. The deductibility of capital losses is subject to limitations under the Code.

Backup Withholding and Information Reporting

Information returns will be filed with the IRS in connection with payments on the notes and the proceeds from a sale or other disposition of the notes. A U.S. Holder will be subject to U.S. backup withholding on these payments if the U.S. Holder fails to timely provide its correct taxpayer identification number to the paying agent and comply with certain certification procedures or otherwise establish an exemption from backup withholding. The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a credit against the U.S. Holder’s U.S. federal income tax liability and may entitle the U.S. Holder to a refund, provided that the required information is timely furnished to the IRS.

Tax Consequences to Non-U.S. Holders

As used in this section, the term “Non-U.S. Holder” means a beneficial owner of a note that is for U.S. federal income tax purposes:

· an individual who is classified as a nonresident for U.S. federal income tax purposes;

· a foreign corporation; or

· a foreign estate or trust.

“Non-U.S. Holder” does not include an individual who is present in the United States for 183 days or more in the taxable year of disposition and who is not otherwise a resident of the United States for U.S. federal income tax purposes. Such an individual is urged to consult his or her own tax advisor regarding the U.S. federal income tax consequences of the sale, exchange or other disposition of a note.

S-34

Subject to the discussion below concerning backup withholding:

· payments of principal and interest on the notes by the Company or any paying agent to any Non-U.S. Holder will not be subject to U.S. federal withholding tax, provided that, in the case of interest,

· the Non-U.S. Holder does not own, actually or constructively, ten percent or more of the total combined voting power of all classes of stock of the Company entitled to vote and is not a controlled foreign corporation related, directly or indirectly, to the Company through stock ownership; and

· the certification requirement described below has been fulfilled with respect to the beneficial owner, as discussed below; and

· a Non-U.S. Holder of a note will not be subject to U.S. federal income tax on gain realized on the sale, exchange or other disposition of such note, unless the gain is effectively connected with the conduct by the holder of a trade or business in the United States, subject to an applicable income tax treaty providing otherwise.

The certification requirement described above generally will be satisfied if the Non-U.S. Holder certifies on IRS Form W-8BEN (or appropriate substitute form), under penalties of perjury, that it is not a U.S. person.

If a Non-U.S. Holder of a note is engaged in a trade or business in the United States, and if income or gain on the note is effectively connected with the conduct of that trade or business, the Non-U.S. Holder, although exempt from the withholding tax referred to above, will generally be taxed in the same manner as a U.S. Holder (see “—Tax Consequences to U.S. Holders” above), subject to an applicable income tax treaty providing otherwise, except that the holder will be required to provide a properly executed IRS Form W-8ECI (or appropriate substitute form) in order to receive payments of interest free of withholding. These holders should consult their tax advisors with respect to other U.S. tax consequences of the ownership and disposition of notes including, with respect to a foreign corporation that is a Non-U.S. Holder, the possible imposition of a branch profits tax on its effectively connected earnings and profits at a rate of 30% (or lower treaty rate).

Backup Withholding and Information Reporting

Information returns will be filed with the IRS in connection with payments of interest on the notes. Unless the Non-U.S. Holder complies with certification procedures to establish that it is not a U.S. person, information returns may be filed with the IRS in connection with the proceeds from a disposition of the notes and the Non-U.S. Holder may be subject to backup withholding with respect to payments on the notes or on the proceeds from a disposition of the notes. Compliance with the certification procedures required to claim the exemption from withholding tax on interest described above will satisfy the certification requirements necessary to avoid backup withholding as well. The amount of any backup withholding from a payment to a Non-U.S. Holder will be allowed as a credit against the Non-U.S. Holder’s U.S. federal income tax liability and may entitle the Non-U.S. Holder to a refund, provided that the required information is timely furnished to the IRS.

UNDERWRITING

We have entered into an underwriting agreement with Morgan Stanley & Co. LLC, as sole underwriter. Under the terms and subject to the conditions contained in the underwriting agreement, we have agreed to sell to the underwriter, and the underwriter has agreed to purchase from us, the principal amount of notes set forth opposite the underwriter’s name:

Underwriter	Principal Amount
Morgan Stanley & Co. LLC	$	250,000,000
Total	$	250,000,000

The underwriting agreement provides that the underwriter is obligated to purchase all the notes in the offering if any are purchased.

The underwriter has agreed to purchase the notes from us at a price equal to         % of the principal amount of the notes, plus accrued interest from April 30, 2013, subject to the terms and conditions in the underwriting agreement between the underwriter and us. The proceeds before expenses and accrued interest to us will be equal to $                    .

The underwriter has advised us that it proposes initially to offer the notes to the public at the public offering price set forth on the cover page of this prospectus supplement. After the initial offering, the public offering price or any other term of the offering may be changed.

We estimate that the total expenses payable by us for this offering, excluding underwriting discounts and commissions and accrued interest, will be approximately $                    .

We have agreed to indemnify the underwriter and its controlling persons against certain liabilities under the Securities Act, or contribute to payments that the underwriter and its controlling persons may be required to make in that respect.

Price Stabilization, Short Positions and Penalty Bids

In connection with the offering of the notes, the underwriter may engage in transactions that stabilize, maintain or otherwise affect the price of the notes. Specifically, the underwriter may overallot in connection with the offering of the notes, creating a syndicate short position. In addition, the underwriter may bid for, and purchase, notes in the open market to cover syndicate short positions or to stabilize the price of the notes. Finally, the underwriter may impose a penalty bid. The underwriter may reclaim selling concessions allowed for distributing the notes in this offering, if the underwriter repurchases previously distributed notes in covering transactions, stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the notes above independent market levels. The underwriter is not required to engage in any of these activities, and may end any of them at any time.

Other Relationships

The underwriter and its affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. The underwriter and its affiliates have, from time to time, performed, and may in the future perform, commercial banking, various financial advisory and investment banking services for us and our affiliates, for which they received or will receive customary fees and expenses. In addition, an affiliate of the underwriter is a lender under our senior secured credit facilities. The underwriter and its affiliates hold a portion of our securities which are subject to

S-36

the Tender Offers, and, therefore, may receive a share of the net proceeds of this offering to the extent such proceeds are used to purchase notes held by them.

In addition, in the ordinary course of their various business activities, the underwriter and its affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve our securities and/or our instruments. The underwriter and its affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

The underwriter or its affiliates routinely hedge, and the underwriter or its affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, the underwriter and its affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby.

SPECIAL NOTE ON FORWARD-LOOKING STATEMENTS

This prospectus, including the documents incorporated by reference herein, contains forward-looking statements. In some cases, you can identify these statements by forward-looking words such as “may,” “might,” “will,” “should,” “expects,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “potential” or “continue,” the negative of these terms and other comparable terminology. These forward-looking statements, which are subject to risks, uncertainties and assumptions about us, may include projections of our future financial performance, our anticipated growth strategies and anticipated trends in our business. These statements are only predictions based on our current expectations and projections about future events. There are important factors that could cause our actual results, level of activity, performance or achievements to differ materially from the results, level of activity, performance or achievements expressed or implied by the forward-looking statements, including those factors discussed under the captions entitled “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended December 31, 2012.

Although we believe the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, level of activity, performance or achievements.
