CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein include certain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Statements in the future tense, and all statements accompanied by terms such as “believe,” “project,” “expect,” “estimate,” “assume,” “intend,” “anticipate,” “target,” “plan” and variations thereof and similar terms, are intended to be forward-looking statements. Forward-looking statements are made subject to the safe harbor protections of the federal securities laws pursuant to Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

Our discussion and analysis in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein contain forward-looking statements regarding our intent, belief and current expectations about our strategic direction, prospects and future results. Such statements give our current expectations or forecasts of future events; they do not relate strictly to historical or current facts. Management believes that these forward-looking statements are reasonable as and when made. However, caution should be taken not to place undue reliance on any such forward-looking statements because such statements speak only as of the date when made.

Forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from our historical experience and our present expectations or anticipated results. These risks and uncertainties include, but are not limited to, those discussed in our filings with the SEC, including our Annual Report on Form 10-K for the year ended December 31, 2018, which is incorporated by reference herein and available from the SEC. You should consider the limitations on, and risks associated with, forward-looking statements and not unduly rely on the accuracy of predictions contained in such forward-looking statements. We do not undertake any obligation to update forward-looking statements to reflect events, circumstances, changes in expectations, or the occurrence of unanticipated events after the date of those statements.

RISK FACTORS

Investing in the notes involves risks. Before making a decision to invest in the notes, you should carefully consider the risks described below and under “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2018, as well as the other information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus. See “Incorporation of Certain Documents by Reference” in this prospectus supplement and “Where You Can Find More Information” in the accompanying prospectus.

Active trading markets for the notes do not exist and may not develop.

There are no established trading markets for the notes since they will be new issues of securities. We do not intend to apply for the listing of the notes on any securities exchange. We cannot assure you as to the liquidity of the public markets for the notes or that any active public markets for the notes of either series will develop or continue. If active public markets do not develop or continue, the market prices and liquidity of the notes may be adversely affected.

If trading markets do develop, changes in our ratings or the financial markets could adversely affect the market prices of the notes.

The market prices of the notes will depend on many factors, including, but not limited to, the following:

The condition of the financial markets and prevailing interest rates have fluctuated in the past and are likely to fluctuate in the future, which could have an adverse effect on the market prices of the notes.

Rating agencies continually review the ratings they have assigned to companies and debt securities. Negative changes in the ratings assigned to us or our debt securities could have an adverse effect on the market prices of the notes.

Ratings of the notes could be lowered in the future.

The rating of the notes will be based primarily on the rating organization’s assessment of the likelihood of timely payment of interest when due on the notes and the ultimate payment of principal of the notes on the final maturity date. Consequently, real or anticipated changes in our credit ratings will generally affect the market value of the notes. We expect that the notes will be rated “investment grade” by one or more nationally recognized statistical rating organizations. However, a rating organization may lower our rating or decide not to rate our securities in its sole discretion. A rating is not a recommendation to purchase, hold or sell the notes, since a rating does not predict the market price of a particular security or its suitability for a particular investor.

S-3

USE OF PROCEEDS

We estimate that the net proceeds to us from this offering will be approximately $                 , after deducting underwriting discounts and commissions and estimated offering expenses payable by us. We intend to use a portion of the net proceeds of this offering to repay at maturity the $1.0 billion outstanding principal amount of our 5.125% Senior Notes due April 1, 2019 (the “2019 Notes”) and the remainder for general corporate purposes. Pending such use of the net proceeds, we may invest the proceeds in highly liquid short-term securities.

The underwriters or certain of their affiliates may be holders of the 2019 Notes. To the extent that net proceeds from this offering are used to repay the 2019 Notes held by such underwriters or such affiliates, such underwriters or affiliates will receive a portion of those net proceeds. See “Underwriting—Other Relationships.”

S-4

CAPITALIZATION

The table below sets forth our consolidated capitalization as of December 31, 2018 on an actual basis and as adjusted to give effect to the issuance and sale of the notes offered hereby and the application of the net proceeds from the sale of the notes. See “Use of Proceeds.”

You should read the table together with our consolidated financial statements and the notes thereto incorporated by reference into this prospectus supplement and the accompanying prospectus.

S-5

DESCRIPTION OF THE NOTES

We are offering $                 aggregate principal amount of our     % Senior Notes due 2029 and $                 aggregate principal amount of our     % Senior Notes due 2049. The 2029 Notes and the 2049 Notes will each constitute a series of senior debt securities described in the accompanying prospectus. The following description supplements, and to the extent it is inconsistent with replaces, the description of the general terms and provisions contained in “Description of the Debt Securities” in the accompanying prospectus. Any capitalized terms that are defined in the accompanying prospectus have the same meanings in this section unless a different definition appears in this section.

Each series of notes will be issued under the indenture dated as of August 26, 2003, as supplemented from time to time, entered into with The Bank of New York Mellon Trust Company, N.A. (as successor to Citibank, N.A.), as trustee. We urge you to read the indenture, because the indenture and the terms included in the notes, not the summaries below and in the accompanying prospectus, define your rights. You may obtain a copy of the indenture from us without charge. See the section entitled “Where You Can Find More Information” in the accompanying prospectus.

General

The notes:

In some circumstances, we may elect to discharge our obligations on the notes through satisfaction and discharge, defeasance or covenant defeasance. See “Description of the Debt Securities—Defeasance and Covenant Defeasance” and “—Defeasance and Discharge” in the accompanying prospectus for more information about how we may do this.

The indenture generally does not limit our ability to incur additional debt and does not contain financial or similar restrictive covenants, except as described in the accompanying prospectus under the caption “Description of the Debt Securities—Additional Covenants.”

Optional Redemption

Each series of notes will be redeemable at any time prior to the applicable Par Call Date (as defined below), as a whole or in part, at our option, on at least 10 days’, but not more than 60 days’, prior notice mailed

S-6

to the registered address of each holder of the notes to be redeemed, at a redemption price equal to the greater of (1) 100% of the principal amount of the notes to be redeemed; and (2) the sum of the present values of the remaining scheduled payments of principal and interest on such series of notes to be redeemed that would be due from the redemption date to the applicable Par Call Date (except that, if such redemption date is not an interest payment date, the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued thereon to the redemption date), discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable discount rate for the notes, plus accrued and unpaid interest to the date of redemption. The discount rate for the 2029 Notes will be the Treasury Rate (as defined below) plus      basis points. The discount rate for the 2049 Notes will be the Treasury Rate (as defined below) plus      basis points.

Each series of notes will be redeemable at any time on or after the applicable Par Call Date, as a whole or in part, at our option, on at least 10 days’, but not more than 60 days’, prior notice mailed to the registered address of each holder of the series of notes to be redeemed, at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest, if any, on the principal amount of the notes to be redeemed to, but excluding, the redemption date.

“Comparable Treasury Issue” means the United States Treasury security or securities selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the notes (assuming for this purpose, such notes mature on the applicable Par Call Date).

“Comparable Treasury Price” means, with respect to any redemption date, (1) the average of the Reference Treasury Dealer Quotations for the redemption date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (2) if we obtain fewer than four such Reference Treasury Dealer Quotations, the average of all Quotations obtained.

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

“Par Call Date” means ,             , 2029, in the case of the 2029 Notes (             months prior to maturity), and             , 2049, in the case of the 2049 Notes (             months prior to maturity).

“Reference Treasury Dealer” means each of BNP Paribas Securities Corp., Goldman Sachs & Co. LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated, Morgan Stanley & Co. LLC, SG Americas Securities, LLC and their respective successors, except that if any of the foregoing ceases to be a primary U.S. Government securities dealer in the United States (a “Primary Treasury Dealer”), we are required to designate as a substitute another nationally recognized investment banking firm that is a Primary Treasury Dealer.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by us, of the bid and asked prices for the applicable Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to us (and provided to the trustee) by such Reference Treasury Dealer as of 3:30 p.m., New York City time, on the third business day immediately preceding the applicable redemption date.

“Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity (computed as of the third business day immediately preceding the redemption date) of the applicable Comparable Treasury Issue, assuming a price for such Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the applicable Comparable Treasury Price for such redemption date.

If money sufficient to pay the redemption price of all of the applicable series of notes to be redeemed on the redemption date is deposited with the trustee or paying agent on or before the redemption date and certain

S-7

other conditions are satisfied, then on and after such redemption date, interest will cease to accrue on such notes called for redemption.

We may at any time, and from time to time, purchase the notes at any price or prices in the open market or otherwise.

Defeasance and Covenants

In some circumstances, we may elect to discharge our obligations on the notes of either series through satisfaction and discharge, defeasance or covenant defeasance. See “Description of the Debt Securities—Defeasance and Covenant Defeasance” and “—Defeasance and Discharge” in the accompanying prospectus for more information about how we may do this.

The indenture generally does not limit our ability to incur additional debt and does not contain financial or similar restrictive covenants, except as described in the accompanying prospectus under the caption “Description of the Debt Securities—Additional Covenants.”

Further Issues

We may from time to time, without notice to or the consent of the registered holders of the applicable series of notes, create and issue further notes of either series. Such further notes may be consolidated and form a single series with such series of the notes and have the same terms as to ranking, redemption or otherwise as such series (other than the issue date and public offering price of such further notes and, if applicable, the first payment of interest following the issue date of such further notes).

Book-Entry System

Upon issuance, each series of notes will be issued in book-entry form through DTC. The notes will be issued as fully registered securities registered in the name of Cede & Co. (DTC’s partnership nominee) or such other name as may be requested by an authorized representative of DTC. Owners of beneficial interests in the notes will receive all payments relating to their debt securities in U.S. dollars. Clearstream and Euroclear may hold interests on behalf of holders of notes through the accounts that each of these systems maintains to facilitate the clearance and settlement of transactions involving the notes.

A description of DTC’s procedures with respect to the notes is set forth in the section “Description of the Debt Securities—Book-Entry, Delivery and Form of Debt Securities” in the accompanying prospectus.

Notices

The trustee will mail notices by first class mail, postage prepaid, to each registered holder’s address as it appears in the security register. The trustee will only mail these notices to the registered holder of the notes, and consequently holders of beneficial interests will not receive these notices unless we reissue the notes in fully certificated form.

Governing Law

The indenture and the notes for all purposes shall be governed by and construed in accordance with the laws of the State of New York.

S-8

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

The following summary describes the material U.S. Federal income and certain estate tax consequences to you of the purchase, beneficial ownership and disposition of notes. This summary deals only with holders that purchase notes in the initial offering at the issue price (i.e., the first price at which a substantial amount of notes is sold to investors) and that hold such notes as capital assets for U.S. Federal income tax purposes. This summary is for general information only and does not address all aspects of U.S. Federal income taxation that may be important to you in light of your particular circumstances, and it does not address state, local, foreign, alternative minimum or non-income tax considerations that may be applicable to you. This summary does not apply to you if you are a member of a class of holders subject to special rules, such as:

This summary is based upon provisions of the Internal Revenue Code of 1986, as amended (the “Code”), and regulations, rulings and judicial decisions as of the date hereof. Those authorities may be changed, perhaps retroactively, or subject to differing interpretations, so as to result in U.S. Federal income tax consequences different from those summarized below.

If an entity classified as a partnership for U.S. Federal income tax purposes holds a note, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. If you are a partnership holding notes or a partner in a partnership holding notes, you should consult your tax advisor as to the particular U.S. Federal income tax consequences applicable to you.

If you are considering the purchase of notes, you should consult your own tax advisor concerning the particular U.S. Federal income and estate tax consequences to you of the purchase, beneficial ownership and disposition of notes, as well as the consequences to you arising under the laws of any other taxing jurisdiction, including any state, local or non-U.S. tax consequences.

For purposes of this summary, a “U.S. holder” means a beneficial owner of a note that is any of the following for U.S. Federal income tax purposes:

S-9

A “non-U.S. holder” means a beneficial owner of a note that is not a U.S. holder and not a partnership for U.S. Federal income tax purposes.

U.S. Holders

Payments or Accruals of Interest

It is anticipated, and the remainder of this discussion assumes, that the notes will not be issued with original issue discount for U.S. Federal income tax purposes. Accordingly, payments or accruals of stated interest on a note will be taxable to you as ordinary interest income at the time that you receive or accrue such amounts in accordance with your regular method of tax accounting.

Sale, Exchange, Retirement or Other Taxable Disposition of Notes

When you sell or exchange a note, or if a note that you hold is retired or otherwise disposed of in a taxable transaction, you generally will recognize gain or loss equal to the difference between the amount you realize on the transaction (less any accrued interest, which will be subject to tax in the manner described above under “Payments or Accruals of Interest”) and your adjusted tax basis in the note.

Your adjusted tax basis in a note generally will equal the cost of the note to you, reduced by any principal payments you previously received in respect of the note.

The gain or loss that you recognize on the sale, exchange, retirement or other disposition of a note generally will be capital gain or loss. The gain or loss on the sale, exchange, retirement or other disposition of a note will be long-term capital gain or loss if you have held the note for more than one year on the date of disposition. Net long-term capital gain recognized by an individual U.S. holder currently is eligible to be taxed at a lower rate than net short-term capital gain or ordinary income. The ability of U.S. holders to offset capital losses against ordinary income is limited.

Additional Tax on Net Investment Income

U.S. holders who are individuals, estates or certain trusts generally will be subject to a 3.8% tax on the lesser of (1) the U.S. person’s “net investment income” in the case of an individual or “undistributed net investment income” in the case of an estate or trust, in each case for the relevant taxable year and (2) the excess of the U.S. person’s modified adjusted gross income in the case of an individual or adjusted gross income in the case of an estate or trust, in each case for the taxable year over a certain threshold (which in the case of individuals will be between $125,000 and $250,000, depending on the individual’s tax return filing status). A U.S. holder’s “net investment income” will generally include any interest income or capital gain recognized by the holder with respect to the notes, unless such income or gain is derived in the ordinary course of the conduct of the holder’s trade or business (other than a trade or business that consists of certain passive or trading activities).

Information Reporting and Backup Withholding

Generally, if you are a non-corporate U.S. holder, payments of interest on a note will be subject to information reporting. In addition, a non-corporate U.S. holder may be subject to a backup withholding tax on

S-10

those payments if it fails to provide its accurate taxpayer identification number to us or our paying agent in the manner required, is notified by the Internal Revenue Service (the “IRS”) that it has failed to report all interest and dividends required to be shown on its U.S. Federal income tax return, or otherwise fails to comply with applicable backup withholding tax rules. In addition, U.S. holders may be subject to information reporting and backup withholding tax with respect to the proceeds from a sale, exchange, retirement or other taxable disposition of a note.

Any amounts withheld from payments to you under the backup withholding tax rules may be allowed as a credit against your U.S. Federal income tax liability and may entitle you to a refund, provided the required information is timely furnished to the IRS.

Non-U.S. Holders

U.S. Federal Withholding Tax

Subject to the discussion below under “—Information Reporting and Backup Withholding” and “Foreign Account Tax Compliance Act (FATCA),” payments of principal and stated interest on a note will not be subject to U.S. Federal withholding tax under the portfolio interest exemption, provided that:

Special certification and other rules apply to certain non-U.S. holders that are entities rather than individuals.

If you do not qualify for the portfolio interest exemption described above and the interest is not effectively connected with your conduct of a trade or business within the United States (as discussed below under “U.S. Federal Income Tax”), payments of interest made to you will be subject to U.S. federal withholding tax at a rate of 30% (or lower applicable treaty rate).

Federal Income Tax

If you are engaged in a trade or business in the United States and interest on the notes is effectively connected with the conduct of that trade or business (and the interest is attributable to a permanent establishment maintained by you in the United States if that is required by an applicable income tax treaty as a condition for subjecting you to U.S. tax on a net income basis), you will be subject to U.S. Federal income tax on that interest on a net income basis (although exempt from the 30% withholding tax, provided you comply with certain certification requirements) in the same manner as if you were a U.S. holder. In addition, if you are a foreign corporation, you may be subject to a branch profits tax equal to 30% (or lower applicable treaty rate) of your effectively connected earnings and profits for the taxable year, subject to certain adjustments, unless you qualify for a lower rate under an applicable income tax treaty.

Any gain (other than any portion of the gain that represents accrued interest in which case the tax rules for interest as described above would apply to such portion) realized on the sale, exchange, retirement or other taxable disposition of a note generally will not be subject to U.S. Federal income or withholding tax unless:

S-11

U.S. Federal Estate Tax

If you are an individual who at death is not a U.S. citizen or resident (as specially defined for U.S. Federal estate tax purposes), your estate will not be subject to U.S. Federal estate tax on notes beneficially owned by you at the time of your death, provided that (1) you do not actually (or constructively) own 10% or more of the total combined voting power of all classes of our voting stock within the meaning of the Code and applicable Treasury regulations, and (2) interest on those notes would not have been, if received at the time of your death, effectively connected with the conduct by you of a trade or business in the United States.

Information Reporting and Backup Withholding

The amount of interest paid to you, and the amount of any tax withheld with respect to such interest, must be reported annually to the IRS and you. Copies of the information returns reporting the amount of such interest and the amount of any tax withheld may also be made available to the tax authorities in the country in which you reside under the provisions of an applicable income tax treaty.

In general, you will not be subject to backup withholding with respect to payments of interest on a note, provided that we do not have actual knowledge or reason to know that you are a United States person, as defined under the Code, and the certification requirements described in the last bullet point under “—U.S. Federal Withholding Tax” above have been met.

In general, you will be subject to information reporting, and possibly backup withholding, with respect to the proceeds of the sale of a note within the United States or conducted through certain U.S.-related financial intermediaries, unless (i) the certification requirements described above have been met and the payor does not have actual knowledge or reason to know that you are a United States person, as defined under the Code, or (ii) you otherwise establish an exemption.

Any amounts withheld from payments to you under the backup withholding tax rules may be allowed as a credit against your U.S. Federal income tax liability and may entitle you to a refund, provided the required information is timely furnished to the IRS.

Foreign Account Tax Compliance Act (FATCA)

Sections 1471 through 1474 of the Code, the treasury regulations promulgated thereunder and other governmental notices with respect thereto (collectively, “FATCA”) could impose a withholding tax of 30% (“FATCA Withholding”) on interest income (including any amount treated as interest for U.S. Federal income tax purposes) and other periodic payments on the notes paid to you or any non-U.S. person or entity that receives such income (a “non-U.S. payee”) on your behalf, unless you and each non-U.S. payee in the payment chain comply with the applicable information reporting, account identification, withholding, certification and other FATCA-related requirements (including any intergovernmental agreement entered into by the United States and another applicable jurisdiction to facilitate the application and implementation of FATCA (an “IGA”)). In the case of a payee that is a non-U.S. financial institution (for example, a clearing system, custodian, nominee or broker), withholding generally will not be imposed if the financial institution complies with the requirements imposed by FATCA to collect and report (to the U.S. or another relevant taxing authority) substantial information regarding such institution’s U.S. account holders (which would include some account holders that are non-U.S. entities but have U.S. owners). Other payees, including individuals, may be required to provide proof of tax residence or waivers of confidentiality laws and/or, in the case of non-U.S. entities, certification or information relating to their U.S. ownership.

S-12

FATCA Withholding may be imposed at any point in a payment chain if a non-U.S. payee is not compliant with the applicable FATCA requirements. A payment chain may consist of a number of parties, including a paying agent, a clearing system, each of the clearing system’s participants and a non-U.S. bank or broker through which you hold the notes. Accordingly, if you receive payments through a payment chain that includes one or more non-U.S. payees the payment could be subject to FATCA Withholding if any non-U.S. payee in the payment chain fails to comply with the FATCA requirements and is subject to withholding. This would be the case even if you would not otherwise have been directly subject to FATCA Withholding.

A number of countries have entered into, and other countries are expected to enter into IGAs. While the existence of an IGA will not eliminate the risk that the notes will be subject to FATCA Withholding, these agreements are expected to facilitate compliance with the FATCA requirements thereby reducing the likelihood that FATCA Withholding will occur for investors in (or investors that indirectly hold notes through financial institutions in) those countries.

FATCA Withholding could apply to all interest (including original issue discount, if any) and other periodic payments made on the notes. In addition, subject to the discussion below regarding proposed Treasury regulations, FATCA Withholding could apply to the gross proceeds payable upon the sale, exchange, redemption or maturity of the notes. Recently proposed Treasury regulations eliminate FATCA Withholding on payments of gross proceeds. Taxpayers may rely on these proposed Treasury regulations until final Treasury regulations are issued. There can be no assurance that final Treasury regulations would provide an exemption from FATCA Withholding for gross proceeds. Under the terms of the notes, we are not obligated to and we will not pay any additional amounts in respect of FATCA Withholding, so if FATCA Withholding applies, you will receive less than the amount that you would have otherwise received.

Depending on your circumstances, you may be entitled to a refund or credit in respect of some or all of any FATCA Withholding. However, even if you are entitled to have any such withholding refunded, the required procedures could be cumbersome and significantly delay your receipt of any withheld amounts.

You are strongly urged to consult your tax advisor regarding FATCA. You should also consult your bank or broker through which you would hold the notes about the likelihood that payments to it (for credit to you) may become subject to FATCA Withholding at some point in the payment chain.

S-13

UNDERWRITING

We intend to offer the notes through the underwriters. BNP Paribas Securities Corp., Goldman Sachs & Co. LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated, Morgan Stanley & Co. LLC and SG Americas Securities, LLC are acting as representatives of the underwriters named below. Subject to the terms and conditions contained in an underwriting agreement between us and the underwriters, we have agreed to sell to the underwriters and the underwriters have severally agreed to purchase from us, the principal amount of the notes listed opposite their names below.

To the extent any underwriter that is not a U.S. registered broker-dealer intends to effect sales of notes in the United States, it will do so through one or more U.S. registered broker-dealers in accordance with the applicable U.S. securities laws and regulations.

The underwriters have agreed to purchase all of the notes of each series sold pursuant to the underwriting agreement if any of the notes are purchased. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the non-defaulting underwriters may be increased or the underwriting agreement may be terminated.

We have agreed to indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the several underwriters may be required to make in respect of those liabilities.

The underwriters are offering the notes, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the notes, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officers’ certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

The underwriters initially propose to offer the notes directly to the public at the public offering prices that appear on the cover page of this prospectus supplement and to certain dealers at that price less a selling concession not in excess of     % of the principal amount of the 2029 Notes and     % of the principal amount of the 2049 Notes. Any underwriter may allow, and such dealers may reallow, a selling concession not in excess of     % of the principal amount of the 2029 Notes and     % of the principal amount of the 2049 Notes, to certain other brokers or dealers. After the initial offering of the notes to the public, the underwriters may vary the offering prices and other selling terms of the notes from time to time.

The expenses of the offering, not including the underwriting discounts, are estimated to be $                 and are payable by us.

New Issues of Notes

There are no established trading markets for the notes. We do not intend to apply for listing of the notes on any securities exchange or for quotation of the notes on any automated dealer quotation system. We have been advised by the underwriters that they presently intend to make a market in the notes of each series after completion of the offering. However, they are under no obligation to do so and may discontinue any market-making activities at any time without any notice. We cannot assure the liquidity of any trading markets for the notes or that active public markets for the notes will develop. If active public trading markets for the notes do not develop, the market prices and liquidity of the notes may be adversely affected.

European Economic Area

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (“EEA”). For these purposes, a “retail investor” means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); or (ii) a customer within the meaning of Directive (EU) 2016/97, where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Directive 2003/71/EC (as amended, the “Prospectus Directive”). No key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling packaged retail and insurance-based investment products or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPS Regulation.

This prospectus supplement has been prepared on the basis that any offer of notes in any member state of the EEA will be made pursuant to an exemption under the Prospectus Directive from the requirement to publish a prospectus for offers of notes. This prospectus supplement is not a prospectus for the purposes of the Prospectus Directive.

United Kingdom

In addition, in the United Kingdom, this document is being distributed only to, and is directed only at, and any offer subsequently made may only be directed at persons who are non-retail investors (being persons who are not retail investors, as defined above) (i) who have professional experience in matters relating to investments falling within Article 19 (5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005, as amended (the “Order”) and/or (ii) who are high net worth companies (or persons to whom it may otherwise be lawfully communicated) falling within Article 49(2)(a) to (d) of the Order (all such persons together being referred to as “relevant persons”). This document must not be acted on or relied on in the United Kingdom by persons who are not relevant persons. In the United Kingdom, any investment or investment activity to which this document relates is only available to, and will only be engaged in with, relevant persons.

Notice to Prospective Investors in Australia

No placement document, prospectus, product disclosure statement or other disclosure document (including as defined in the Corporations Act 2001 (Cth) (“Corporations Act”)) has been or will be lodged with the Australian Securities and Investments Commission (“ASIC”) or any other governmental agency, in relation to the offering. This prospectus supplement does not constitute a prospectus, product disclosure statement or other disclosure document for the purposes of Corporations Act, and does not purport to include the information required for a prospectus, product disclosure statement or other disclosure document under the Corporations Act. No action has been taken which would permit an offering of the notes in circumstances that would require disclosure under Parts 6D.2 or 7.9 of the Corporations Act.

The notes may not be offered for sale, nor may application for the sale or purchase or any notes be invited in Australia (including an offer or invitation which is received by a person in Australia) and neither this prospectus supplement nor any other offering material or advertisement relating to the notes may be distributed or published in Australia unless, in each case:

Price Stabilization and Short Positions

In connection with the offering, the underwriters are permitted to engage in transactions that stabilize the market prices of the notes. Such transactions consist of bids or purchases to peg, fix or maintain the prices of the notes. If the underwriters create any short positions in the notes in connection with the offering, i.e., if they sell more notes than are on the cover page of this prospectus, the underwriters may reduce such short positions by purchasing notes in the open market. Purchases of a security to stabilize the price or to reduce a short position could cause the price of the security to be higher than it might be in the absence of such purchases.

The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays a portion of the underwriting discount received by it because the representatives have repurchased notes sold by or for the account of such underwriter in stabilizing or short covering transactions.

Neither we nor any of the underwriters makes any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the prices of the notes. In addition, neither we nor any of the underwriters makes any representation that the underwriters will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

S-18

Other Relationships

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include sales and trading, commercial and investment banking, advisory, investment management, investment research, principal investment, hedging, market making, brokerage and other financial and non-financial activities and services. Some of the underwriters and their affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us or our affiliates. They have received, or may in the future receive, customary fees and commissions for these transactions. In particular, affiliates of each of BNP Paribas Securities Corp., Goldman Sachs & Co. LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated, Morgan Stanley & Co. LLC and SG Americas Securities, LLC are lenders, agents or arrangers under one or both of our existing revolving credit facilities.

The underwriters or certain of their affiliates may be holders of the 2019 Notes. To the extent that net proceeds from this offering are used to repay the 2019 Notes held by such underwriters or such affiliates, such underwriters or affiliates will receive a portion of those net proceeds.

In addition, in the ordinary course of their business activities, the underwriters and their 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. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. Certain of the underwriters or their affiliates that have a lending relationship with us routinely hedge, and certain other of those underwriter or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, such underwriters and their 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. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

Retrospective Presentation for Change in Accounting Principle

In May 2015, the Financial Accounting Standards Board issued an accounting standards update that changes the disclosure requirement for reporting investments at fair value. This update removes the requirement to categorize investments for which fair value is measured using the net asset value (“NAV”) per share practical expedient within the fair value hierarchy. These disclosures are limited to investments for which the entity has elected to measure fair value using the practical expedient. Substantially all of our Level 3 pension and postretirement benefit plan assets were measured using NAV as a practical expedient. This guidance became effective for us in the first quarter of 2016 and did not have a material impact on our consolidated financial position, results of operations or cash flows.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the documents incorporated by reference herein may contain statements, estimates or projections that constitute “forward-looking statements” as defined under U.S. federal securities laws. The words “believe,” “project,” “expect,” “estimate,” “assume,” “intend,” “anticipate,” “target,” “plan,” and variations thereof and similar expressions are intended to identify forward-looking statements. These statements include statements regarding our intent, belief and current expectations about our strategic direction, prospects, future results and other matters. These forward-looking statements are based on beliefs and assumptions of our management, and involve certain risks and uncertainties which could cause actual results to differ materially from those contained in any forward-looking statement.

USE OF PROCEEDS

Unless we otherwise specify in the applicable prospectus supplement, the net proceeds we receive from the sale of the securities offered by this prospectus and the accompanying prospectus supplement will be used for general corporate purposes. General corporate purposes may include the repayment of debt, investments in or extensions of credit to our subsidiaries, financing working capital needs, funding capital expenditures, or the financing of possible acquisitions or business expansion. The net proceeds may be invested temporarily or applied to repay short-term debt until they are used for their stated purpose.

RATIO OF EARNINGS TO FIXED CHARGES

For purposes of calculating the ratio of earnings to fixed charges, earnings are defined as income before income taxes and fixed charges (excluding capitalized interest). Fixed charges include interest (whether capitalized or expensed), amortization of debt issuance costs and any discount or premium relating to any indebtedness (whether capitalized or expensed) and the portion of rent expense considered to represent interest.

The following table sets forth our consolidated ratio of earnings to fixed charges.

DESCRIPTION OF THE DEBT SECURITIES

Description of Debt Securities

We will issue the debt securities under an indenture, dated as of August 26, 2003, between us and The Bank of New York Mellon Trust Company, N.A. (formerly known as The Bank of New York Trust Company, N.A.), as successor to Citibank, N.A., which acts as trustee. We have summarized the material provisions of the indenture below. The indenture has been filed as an exhibit to the registration statement on Form S-3 (No. 333-108272), filed with the SEC on August 27, 2003, and you should read the indenture for provisions that may be important to you. In the summary below, we have included references to section numbers of the indenture so that you can easily locate these provisions. Capitalized terms used in the summary have the meaning specified in the indenture. You can obtain copies of the indenture by following the directions described in the Section entitled “Where You Can Find More Information.”

General

The indenture does not limit the aggregate principal amount of debt securities that we may issue and provides that we may issue debt securities from time to time in one or more series, in each case with the same or various maturities, at par or at a discount. We may issue additional debt securities of a particular series without the consent of the holders of the debt securities of such series outstanding at the time of the issuance. Any such additional debt securities, together with all other outstanding debt securities of that series, will constitute a single series of debt securities under the indenture. The indenture also generally does not limit our ability to incur additional debt and does not contain financial or similar restrictive covenants. The debt securities will be unsecured and will rank equally with all of our other senior debt and senior to our subordinated debt, if any.

Unless we inform you otherwise in a prospectus supplement, the indenture does not contain any debt covenants or other provisions that would protect holders of the debt securities in the event we participate in a highly leveraged or other transaction that may adversely affect our creditworthiness.

A prospectus supplement relating to a series of debt securities being offered will include specific terms relating to the offering. These terms will include some or all of the following:

6

We may sell the debt securities, including original issue discount securities, at a substantial discount below their principal amount. Original issue discount securities bear no interest or bear interest at below market

7

rates. We may describe special United States federal income tax considerations, if any, applicable to the debt securities sold at an original issue discount in the applicable prospectus supplement. In addition, we may describe special United States federal income tax or other considerations, if any, applicable to the debt securities that are sold for any foreign currency or currency unit or if any payments on the debt securities are payable in any foreign currency or currency unit, in the applicable prospectus supplement. We encourage you to consult with your own competent tax and financial advisors on these important matters.

Consolidation, Merger and Sale of Assets

We may not consolidate with or merge with or into any other person or convey, transfer or lease all or substantially all of our properties and assets substantially as an entirety to any person unless:

Upon any consolidation or merger or any conveyance, transfer or lease of all or substantially all of our properties and assets in accordance with these provisions, the successor person formed by a consolidation, or into which we are merged or the successor person to which any conveyance, transfer or lease is made, shall succeed to, and be substituted for, and may exercise every right and power of ours under the debt securities and the indenture with the same effect as if that successor had been named as us therein; and thereafter, except in the case of a lease, we shall be discharged from all obligations and covenants under the debt securities and indenture. (Sections 8.01 and 8.02)

Additional Covenants

Although the indenture generally does not contain financial or similar restrictive covenants, unless otherwise specified in any applicable prospectus supplement, the debt securities will contain the additional covenants described below that are not contained in the indenture.

Limitation on Secured Indebtedness

We will not create, assume, incur or guarantee, and will not permit any Restricted Subsidiary to create, assume, incur or guarantee, any Secured Indebtedness without making provision whereby the debt securities shall be secured equally and ratably with, or prior to, such Secured Indebtedness, together with, if we shall so

8

determine, any other Indebtedness of us or any Restricted Subsidiary then existing or thereafter created that is not subordinate to the debt securities, so long as the Secured Indebtedness shall be outstanding, unless the Secured Indebtedness, when added to:

would not exceed 10% of Consolidated Net Tangible Assets.

Limitation on Sale and Lease Back Transactions

We will not, and will not permit any Restricted Subsidiary to, enter into any Sale and Leaseback Transaction unless (a) the sum of:

would not exceed 10% of Consolidated Net Tangible Assets, or (b) an amount equal to the greater of:

is applied to the retirement of Funded Debt of us or any Restricted Subsidiaries (other than Funded Debt that is subordinate to the debt securities or is owing to us or any Restricted Subsidiaries or is scheduled to mature within one year after consummation of such Sale and Leaseback Transaction) within 180 days after the consummation of such Sale and Leaseback Transaction.

Definitions

As used in this prospectus, the following definitions apply:

“Attributable Debt” means, as of the date of its determination, the present value (discounted semi-annually at an interest rate of 7.0% per annum) of the obligation of a lessee for rental payments pursuant to any Sale and Leaseback Transaction (reduced by the amount of the rental obligations of any sublessee of all or part of

9

the same property) during the remaining term of such Sale and Leaseback Transaction (including any period for which the lease relating thereto has been extended), such rental payments not to include amounts payable by the lessee for maintenance and repairs, insurance, taxes, assessments and similar charges and for contingent rents (such as those based on sales). In the case of any Sale and Leaseback Transaction in which the lease is terminable by the lessee upon the payment of a penalty, the rental payments shall be considered for purposes of this definition to be the lesser of the discounted values of:

a. the rental payments to be paid under such Sale and Leaseback Transaction until the first date (after the date of such determination) upon which it may be so terminated plus the then applicable penalty upon such termination; and

b. the rental payments required to be paid during the remaining term of such Sale and Leaseback Transaction (assuming such termination provision is not exercised).

“Capitalized Lease Obligation” means any obligation to pay rent or other amounts under a lease of (or other agreement conveying the right to use) real or personal property that is required to be classified and accounted for as a capital lease obligation under generally accepted accounting principles, and, for the purposes of the debt securities, the amount of such obligation at any date shall be the capitalized amount thereof at the applicable date, determined in accordance with such principles.

12

13

In no event shall the foregoing provisions be interpreted to mean that the same Indebtedness is included more than once in the calculation of “Secured Indebtedness” as that term is used in the debt securities.

Events of Default

The indenture defines an Event of Default with respect to any series of debt securities as any one of the following events:

If an Event of Default occurs and is continuing with respect to the debt securities of any series, other than an Event of Default referred to in clause (5) above, either the trustee or the holders of 25% in principal amount, or if the debt securities are not payable at maturity for a fixed principal amount, 25% of the aggregate issue price, of the outstanding debt securities of that series, each series acting as a separate class, may declare the principal of the debt securities of that series, or an other amount or property, as may be provided for in the debt securities of that series, to be due and payable. If an Event of Default described in clause (5) above with respect to the debt securities of any series at the time outstanding shall occur, the principal amount of all the debt securities of that series, or such other amount or property, as may be provided for in the debt securities of that series (or, in the case of any original issue discount security, such portion of the principal as may be specified in its terms) will automatically, and without any action by the trustee or any holder, become immediately due and payable. (Section 5.02). The holders of not less than a majority in aggregate principal amount of the outstanding debt securities of a series may, on behalf of all holders of debt securities of the series, waive any past default under the indenture with respect to the debt securities of the series, except a default in the delivery or payment of the maturity consideration or interest on any debt security of the series, and default in respect of a covenant or provision of the indenture that cannot be modified or amended without the consent of the holder of each outstanding debt security of the affected series. (Section 5.13)

Subject to the provisions of the indenture relating to the duties of the trustee in case an Event of Default shall occur and be continuing, the trustee will be under no obligation to exercise any of its rights or powers under

14

the indenture at the request or discretion of any of the holders, unless the holders shall have offered to the trustee security or indemnity satisfactory to the trustee. (Section 6.03). Subject to such provisions for the indemnification of the trustee, the holders of a majority in aggregate principal amount of the outstanding debt securities of any series will have the right to 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 the debt securities of that series. (Section 5.12)

No holder of a debt security of any series will have any right to institute any proceeding with respect to the indenture, or for the appointment of a receiver or a trustee, or for any other remedy under the indenture, unless

However, these limitations do not apply to a suit instituted by a holder of a debt security for the enforcement of delivery or payment of the maturity consideration relating to, or interest on, the debt security on or after the applicable due date specified in the debt security. (Section 5.08)

We will be required to furnish to the trustee annually a statement by certain of our officers as to whether or not we, to our knowledge, are in default in the performance or observance of any of the terms, provisions and conditions of the indenture and, if so, specifying all known defaults. (Section 10.04)

Street name and other indirect holders should consult their banks and brokers for information on their requirements for giving notice or taking other actions on a default.

Defeasance and Covenant Defeasance

If and to the extent indicated in any applicable prospectus supplement, we may elect, at our option at any time, to have the provisions of Section 13.02 of the indenture, relating to defeasance and discharge of Indebtedness, or Section 13.03 of the indenture, relating to defeasance of certain restrictive covenants in the indenture, applied to the debt securities of any series, or to any specified part of a series. Defeasance refers to the discharge of some or all of our obligations under the indenture. (Section 13.01)

Defeasance and Discharge

The indenture provides that, upon our exercise of our option to have Section 13.02 of the indenture apply to any debt securities, we will be deemed to have been discharged from all obligations with respect to the debt securities (except for certain obligations to exchange or register the transfer of debt securities, to replace

15

stolen, lost or mutilated debt securities, to maintain paying agencies and to hold money for payment in trust) upon the irrevocable deposit in trust for the benefit of the holders of the debt securities of money or U.S. Government Obligations, or both, which, through the payment of principal and interest in respect thereof in accordance with their terms, will provide money in an amount sufficient to pay the principal of and any premium and interest on the debt securities on the respective Stated Maturities in accordance with the terms of the indenture and the debt securities. Defeasance or discharge may occur only if, among other things, we have delivered to the trustee an opinion of counsel to the effect that, we have received from, or there has been published by, the United States Internal Revenue Service a ruling, or there has been a change in tax law, in any case to the effect that holders of the debt securities will not recognize gain or loss for federal income tax purposes as a result of the deposit, defeasance and discharge and will be subject to federal income tax on the same amount, in the same manner and at the same times as would have been the case if the deposit, defeasance and discharge were not to occur. (Sections 13.02 and 13.04)

Defeasance of Covenants

The indenture provides that, upon our exercise of our option to have Section 13.03 of the indenture apply to any debt securities, we may omit to comply with and shall have no liability in respect of certain restrictive covenants, including those that may be described in the applicable prospectus supplement, and the occurrence of certain Events of Default, which are described above in clause (4) (with respect to restrictive covenants) and under “Events of Default” and any that may be described in the applicable prospectus supplement, will be deemed not to be or result in an Event of Default, in each case with respect to the debt securities. In order to exercise this option, we will be required to irrevocably deposit, in trust for the benefit of the holders of the debt securities, money or U.S. Government Obligations, or both, which, through the payment of principal and interest in respect thereof in accordance with their terms, will provide money in an amount sufficient to pay the principal of and any premium and interest on the debt securities on the respective Stated Maturities in accordance with the terms of the indenture and the debt securities. We will also be required, among other things, to deliver to the trustee an opinion of counsel to the effect that holders of the debt securities will not recognize gain or loss for federal income tax purposes as a result of deposit and defeasance of certain obligations and will be subject to federal income tax on the same amount, in the same manner and at the same times as would have been the case if the deposit and defeasance were not to occur. In the event we exercised this option with respect to any debt securities and the debt securities were declared due and payable because of the occurrence of any Event of Default, the amount of money and U.S. Government Obligations so deposited in trust would be sufficient to pay amounts due on the debt securities at the time of their respective Stated Maturities but may not be sufficient to pay amounts due on the debt securities upon any acceleration resulting from the Event of Default. In that case, we would remain liable for the payments. (Sections 13.03 and 13.04)

Modification of the Indenture

The indenture provides that we and the trustee may, without the consent of any holders of debt securities, enter into supplemental indentures for the purpose, among other things, of adding to our covenants, adding additional Events of Default, establishing the form or terms of debt securities or curing ambiguities or inconsistencies in the indenture or making other provisions, provided that any action to cure ambiguities or inconsistencies not adversely affect the interests of the holders of any outstanding series of debt securities in any material respect. (Section 9.01)

Modifications and amendments of the indenture may be made by us and the trustee with the consent of the holders of a majority in aggregate principal amount or, if the debt securities are not payable at maturity for a fixed principal amount, the aggregate issue price, of the outstanding debt securities of each series affected thereby, except that no modification or amendment may, without the consent of the holder of each outstanding debt security affected thereby,

16

A supplemental indenture that changes or eliminates any covenant or other provision of the indenture which has been expressly included solely for the benefit of one or more particular series of debt securities, or that modifies the rights of the holders of debt securities of the series with respect to the covenant or other provision, shall be deemed not to affect the rights under the indenture of the holders of debt securities of any other series. (Section 9.02)

The holders of a majority in aggregate principal amount of the outstanding debt securities of a series may, on behalf of the holders of all the debt securities of the series, waive compliance by us with certain restrictive provisions of the indenture. (Section 10.07)

Form, Exchange and Transfer

Subject to the terms of the indenture and the limitations applicable to global securities, debt securities may be presented for exchange as provided above or for registration of transfer (duly endorsed or with the form of transfer endorsed thereon duly executed) at the office of the security registrar or at the office of any transfer agent we designate for such purpose. No service charge will be made for any registration of transfer or exchange of debt securities, but we may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. Registration of transfer or exchange will be effected by the security registrar or the transfer agent, as the case may be, when the security registrar or transfer agent is satisfied with the documents of title and identity of the person making the request. We have appointed the trustee as security registrar. (Section 3.05)

We may at any time designate additional transfer agents or rescind the designation of any transfer agent or approve a change in the office through which any transfer agent acts, except that we will be required to maintain a transfer agent in each place of payment for the debt securities of each series. (Section 10.02)

If debt securities of any series are to be redeemed in part, we will not be required to:

17

Payment and Paying Agents

Unless otherwise indicated in the applicable prospectus supplement, payment of interest on a debt security on any Interest Payment Date will be made to the person in whose name the security, or one or more predecessor securities, is registered at the close of business on the Regular Record Date for payment of interest. (Section 3.07)

Unless otherwise indicated in the applicable prospectus supplement, principal of and any premium, maturity consideration and interest on the debt securities of a particular series (other than a global security) will be payable or deliverable at the office of the paying agent or paying agents as we may designate for that purpose from time to time, except that at our option payment of any interest may be made by check mailed to the address of the person entitled to the payment as that address appears in the security register. Unless otherwise indicated in the applicable prospectus supplement, the corporate trust office of the trustee in The City of New York will be designated as our sole paying agent for payments and deliveries with respect to debt securities of each series. Any other paying agents initially designated for the debt securities of a particular series will be named in the applicable prospectus supplement. We may at any time designate additional paying agents or rescind the designation of any paying agent or approve a change in the office through which any paying agent acts, except that we will be required to maintain a paying agent in each place of payment for the debt securities of a particular series. (Section 10.02)

All consideration paid or delivered to a paying agent for the payment or delivery of the principal of or any premium, maturity consideration or interest on any debt security that remains unclaimed at the end of two years after such principal, premium, maturity consideration or interest has become due and payable or deliverable will be repaid to us, and the holder of the debt security thereafter, as an unsecured general creditor, may look only to us for payment or delivery thereof. (Section 10.03)

Book-Entry, Delivery and Form of Debt Securities

The debt securities will be issued in book-entry form through The Depository Trust Company, which we refer to along with its successors in this capacity as “DTC.” DTC will act as securities depositary for the debt securities. The debt securities will be issued only as fully registered securities registered in the name of Cede & Co. (DTC’s partnership nominee) or such other name as may be requested by an authorized representative of DTC. The debt securities will be accepted for clearance by DTC. Beneficial interests in the debt securities will be shown on, and transfers thereof will be effected only through, the book-entry records maintained by DTC and its direct and indirect participants, including Euroclear and Clearstream as described below. Owners of beneficial interests in the debt securities will receive all payments relating to their debt securities in U.S. dollars. One or more fully registered global security certificates, representing the aggregate principal amount of debt securities issued, will be issued and will be deposited with DTC and will bear a legend regarding the restrictions on exchanges and registration of transfer referred to below.

The laws of some jurisdictions may require that some purchasers of securities take physical delivery of securities in definitive form. These laws may impair the ability to transfer beneficial interests in the debt securities, so long as the debt securities are represented by global security certificates.

DTC has advised us that it is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds securities that its direct participants deposit with DTC. DTC also facilitates the post-trade settlement among

18

direct participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between participants’ accounts. This eliminates the need for physical movement of securities certificates. Direct participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation, which, in turn, is owned by a number of direct participants of DTC and by the New York Stock Exchange, Inc., the American Stock Exchange LLC and the Financial Industry Regulatory Authority, Inc. Access to the DTC system is also available to others, referred to as “indirect participants,” such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies and clearing corporations that clear through or maintain a direct or indirect custodial relationship with a direct participant. The rules applicable to DTC and its participants are on file with the SEC.

Purchases of debt securities under the DTC system must be made by or through direct participants, which will receive a credit for the debt securities on DTC’s records. The ownership interest of each beneficial owner of debt securities will be recorded on the direct or indirect participants’ records. Beneficial owners will not receive written confirmation from DTC of their purchase. Beneficial owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the direct or indirect participant through whom the beneficial owner entered into the transaction. Under a book-entry format, holders may experience some delay in their receipt of payments, as such payments will be forwarded by the trustee to Cede & Co., as nominee for DTC. DTC will forward the payments to its participants, who will then forward them to indirect participants or holders. Beneficial owners of debt securities other than DTC or its nominees will not be recognized by the registrar and transfer agent as registered holders of the debt securities entitled to the rights of holders thereof. Beneficial owners that are not participants will be permitted to exercise their rights only indirectly through and according to the procedures of participants and, if applicable, indirect participants.

To facilitate subsequent transfers, all debt securities deposited by direct participants with DTC are registered in the name of DTC’s partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of debt securities with DTC and their registration in the name of Cede & Co. or such other DTC nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the debt securities; DTC’s records reflect only the identity of the direct participants to whose accounts the debt securities are credited, which may or may not be the beneficial owners. The direct and indirect participants will remain responsible for keeping account of their holdings on behalf of their customers.

Delivery of notices and other communications by DTC to direct participants, by direct participants to indirect participants, and by direct and indirect participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time. Redemption notices, if any, will be sent to DTC. If less than all of the debt securities within an issue are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each direct participant in such issue to be redeemed.

Neither DTC nor Cede & Co. (nor any other DTC nominee) will consent or vote with respect to debt securities unless authorized by a direct participant in accordance with DTC’s procedures. Under its usual procedures, DTC mails an omnibus proxy to the issuer as soon as possible after the record date. The omnibus proxy assigns Cede & Co.’s consenting or voting rights to those direct participants to whose accounts debt securities are credited on the record date (identified in a listing attached to the omnibus proxy).

DTC may discontinue providing its services as securities depositary with respect to the debt securities at any time by giving reasonable notice to the issuer or its agent. Under these circumstances, in the event that a successor securities depositary is not obtained, certificates for the debt securities are required to be printed and delivered. We may decide to discontinue the use of the system of book-entry-only transfers through DTC (or a

19

successor securities depositary). In that event, certificates for the debt securities will be printed and delivered to DTC. If an event of default with respect to the debt securities has occurred and is continuing, a holder may request that certificates for the debt securities be registered in such holder’s names.

As long as DTC or its nominee is the registered owner of the global security certificates, DTC or its nominee, as the case may be, will be considered the sole owner and holder of the global security certificates and all debt securities represented by these certificates for all purposes under the instruments governing the rights and obligations of holders of debt securities. Except in the limited circumstances referred to above, owners of beneficial interests in global security certificates:

Payments with respect to debt securities represented by the global security certificates and all transfers and deliveries of debt securities will be made to DTC or its nominee, as the case may be, as the registered holder of the debt securities. DTC’s practice is to credit direct participants’ accounts upon DTC’s receipt of funds and corresponding detail information from the issuer or its agent, on the payable date in accordance with their respective holdings shown on DTC’s records. Payments by participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of that participant and not of DTC, the trustee, the issuer or any of their agents, subject to any statutory or regulatory requirements as may be in effect from time to time. Payments to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) are the responsibility of the issuer or its agent, disbursement of such payments to direct participants will be the responsibility of DTC, and disbursement of such payments to the beneficial owners will be the responsibility of direct and indirect participants.

Ownership of beneficial interests in the global security certificates will be limited to participants or persons that may hold beneficial interests through institutions that have accounts with DTC or its nominee. Ownership of beneficial interests in global security certificates will be shown only on, and the transfer of those ownership interests will be effected only through, records maintained by DTC or its nominee, with respect to participants’ interests, or any participant, with respect to interests of persons held by the participant on their behalf. Payments, transfers, deliveries, exchanges, and other matters relating to beneficial interests in global security certificates may be subject to various policies and procedures adopted by DTC from time to time. Neither we nor any agent for us will have any responsibility or liability for any aspect of DTC’s or any direct or indirect participant’s records relating to, or for payments made on account of, beneficial interests in global security certificates, or for maintaining, supervising or reviewing any of DTC’s records or any direct or indirect participant’s records relating to these beneficial ownership interests.

Although DTC has agreed to the foregoing procedures in order to facilitate transfer of interests in the global security certificates among participants, DTC is under no obligation to perform or continue to perform these procedures, and these procedures may be discontinued at any time. We will not have any responsibility for the performance by DTC or its direct or indirect participants under the rules and procedures governing DTC.

Because DTC can act only on behalf of direct participants, who in turn act only on behalf of direct or indirect participants, and certain banks, trust companies and other persons approved by it, the ability of a beneficial owner of debt securities to pledge the debt securities to persons or entities that do not participate in the DTC system may be limited due to the unavailability of physical certificates for the debt securities.

20

DTC has advised us that it will take any action permitted to be taken by a registered holder of any securities under the indenture only at the direction of one or more participants to whose accounts with DTC the debt securities are credited.

The information in this section concerning DTC and its book-entry system has been obtained from sources that we believe to be accurate, but we assume no responsibility for the accuracy thereof.

If the depositary for a global security is DTC, you may hold interests in the global debt securities through Euroclear Bank S.A./N.V., as operator of the Euroclear System (“Euroclear”) or Clearstream Banking, société anonyme (“Clearstream”), in each case, as a participant in DTC. Clearstream and Euroclear will hold interests on behalf of their participants through customers’ securities accounts in Clearstream’s and Euroclear’s names on the books of their respective depositaries, which in turn will hold interests in customers’ securities accounts in the depositaries’ names on the books of DTC.

Payments, deliveries, transfers, exchanges, notices and other matters relating to the debt securities made through Euroclear or Clearstream must comply with the rules and procedures of those systems. Those systems could change their rules and procedures at any time. The Company has no control over those systems or their participants, and the Company takes no responsibility for their activities. Transactions between participants in Euroclear or Clearstream, on the one hand, and other participants in DTC, on the other hand, would also be subject to DTC’s rules and procedures.

Investors will be able to make and receive through Euroclear and Clearstream payments, deliveries, transfers, exchanges, notices and other transactions involving any securities held through those systems only on days when those systems are open for business. Those systems may not be open for business on days when banks, brokers and other institutions are open for business in the United States.

In addition, because of time-zone differences, U.S. investors who hold their interests in the debt securities through Euroclear or Clearstream and wish, on a particular day, to transfer their interests, or to receive or make a payment or delivery or exercise any other right with respect to their interests, may find that the transaction will not be effected until the next business day in Brussels or Luxembourg, as applicable. Thus, investors who wish to exercise rights that expire on a particular day may need to act before such date. In addition, investors who hold their interests through both DTC and Euroclear or Clearstream may need to make special arrangements to finance any purchase or sales of their interests between the U.S. and European clearing systems, and those transactions may settle later than transactions within one clearing system.

The information in this section concerning Euroclear and Clearstream and their book-entry systems has been obtained from sources that we believe to be reliable, but we take no responsibility for the accuracy of that information.

None of us, any of the underwriters or the trustee will have any responsibility for the performance by Euroclear or Clearstream or their respective participants of their respective obligations under the rules and procedures governing their operations.

Although DTC, Clearstream and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of securities among participants of DTC, Clearstream and Euroclear, they are under no obligation to perform or continue to perform such procedures and they may discontinue the procedures at any time.

Notices

Notices to holders of debt securities will be given by mail to the addresses of the holders as they may appear in the security register. (Section 1.06)

21

Title

We, the trustee and any agent of ours or the trustee’s may treat the Person in whose name a debt security is registered as the absolute owner of a debt security for the purpose of making payment and for all other purposes. (Section 3.08)

Governing Law

The indenture and the debt securities will be governed by, and construed in accordance with, the law of the State of New York. (Section 1.12)

Regarding The Trustee

The Bank of New York Mellon Trust Company, N.A. (formerly known as The Bank of New York Trust Company, N.A.), as successor to Citibank, N.A., is the trustee under the indenture. We have other customary banking relationships with The Bank of New York Mellon in the ordinary course of business.

DESCRIPTION OF THE PREFERRED STOCK

The following is a description of general terms and provisions of the preferred stock. The particular terms of any series of preferred stock will be described in the applicable prospectus supplement.

All of the terms of the preferred stock are, or will be, contained in our Restated Certificate of Incorporation or any resolutions which may be adopted by our board of directors relating to any series of the preferred stock, which will be filed with the SEC at or before the time we issue a series of the preferred stock.

We are authorized to issue up to 200,000,000 shares of preferred stock, par value $0.01 per share. As of the date of this prospectus, we have no shares of preferred stock outstanding. Subject to limitations prescribed by law, the board of directors is authorized at any time to:

The board of directors is authorized to determine, for each series of preferred stock, and the prospectus supplement will set forth with respect to the series, the following information:

The preferred stock, when issued, will be fully paid and nonassessable.

Although it has no present intention to do so, our board of directors, without shareowner approval, may issue preferred stock with voting and conversion rights, which could adversely affect the voting power of the holders of common stock. If we issue preferred stock, it may have the effect of delaying, deferring or preventing a change of control.

23

DESCRIPTION OF THE COMMON STOCK

We are authorized to issue a total of 10,200,000,000 shares of common stock, of which:

As of September 30, 2016, 183,668,423 shares of class A common stock were outstanding and 689,333,425 shares of class B common stock were outstanding.

We will issue only shares of class B common stock pursuant to this prospectus.

Generally, all shares of our common stock have the same relative rights, preferences and limitations, except as follows:

Our class B common stock is listed and traded on the New York Stock Exchange under the symbol “UPS.” There is no public market for our class A common stock.

Dividends may be paid on our common stock out of funds legally available for dividends, when and if declared by our board of directors. In the case of a distribution of our common stock, each class of common stock receives a distribution of only shares of the same class of common stock. For example, only shares of class B common stock may be distributed with respect to class B common stock.

Holders of our common stock are entitled to share ratably in any dividends and in any assets available for distribution on liquidation, dissolution or winding-up, subject, if any of our preferred stock is then outstanding, to any preferential rights of such preferred stock. Our common stock is not redeemable, has no subscription rights and does not entitle the holder to any preemptive rights.

Anti-takeover Effects of our Certificate of Incorporation, Bylaws and Delaware Law

Restated Certificate of Incorporation and Amended and Restated Bylaws

Our Restated Certificate of Incorporation and Amended and Restated Bylaws contain provisions that may be deemed to have an anti-takeover effect and may delay, defer or prevent a tender offer or takeover attempt that a shareowner might consider in its best interest. These provisions include:

24

These provisions are designed to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors. We believe that this increased protection gives us the potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us, and that the benefits of this increased protection outweigh the disadvantages of discouraging those proposals, because negotiation of those proposals could improve their terms.

Delaware Business Combination Statute

We are subject to Section 203 of the Delaware General Corporation Law, an anti-takeover law. Section 203 imposes restrictions which, under certain circumstances, may make it more difficult for an “interested stockholder”, as defined in Section 203, to effect various business combinations with us for a three-year period from the time such person becomes an interested stockholder. Under Section 203, a corporation’s bylaws or certificate of incorporation may exclude a corporation from the restrictions imposed by Section 203. Neither our bylaws nor our certificate of incorporation contains such an exclusion.

25

DESCRIPTION OF THE WARRANTS

We may issue warrants for the purchase of debt securities, preferred stock or class B common stock. Warrants may be issued independently or together with our debt securities, preferred stock or class B common stock and may be attached to or separate from any offered securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a bank or trust company, as warrant agent. The warrant agent will act solely as our agent in connection with the warrants and will not have any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants. A copy of the warrant agreement will be filed with the SEC in connection with the offering of warrants.

Debt Warrants

The prospectus supplement relating to a particular issue of warrants to purchase debt securities will describe the terms of those warrants, including the following:
