CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

The statements, estimates, projections, guidance or outlook contained in, or incorporated by reference into, this prospectus supplement and the accompanying prospectus include “forward-looking” statements which are intended to take advantage of the “safe harbor” provisions of the federal securities laws. The words “believe,” “expect,” “intend,” “estimate,” “anticipate,” “forecast,” “outlook,” “plan,” “project,” “should” and similar expressions identify forward-looking statements. These statements may contain information about financial prospects, economic conditions and trends and involve risks and uncertainties. Actual results could differ materially from those that management expects, depending on the outcome of certain factors including: our ability to effectively estimate, price for and manage medical costs; new or changes in existing health care laws or regulations, or their enforcement or application; reductions in revenue or delays to cash flows received under government programs; changes in Medicare, the Centers for Medicare & Medicaid Services star ratings program or the application of risk adjustment data validation audits; the Department of Justice’s legal action relating to the risk adjustment submission matter; our ability to maintain and achieve improvement in quality scores impacting revenue; failure to maintain effective and efficient information systems or if our technology products do not operate as intended; cyberattacks, other privacy/data security incidents, or our failure to comply with related regulations; risks and uncertainties associated with our businesses providing pharmacy care services; competitive pressures, including our ability to maintain or increase our market share; changes in or challenges to our public sector contract awards; failure to achieve targeted operating cost productivity improvements; failure to develop and maintain satisfactory relationships with health care payers, physicians, hospitals and other service providers; the impact of potential changes in tax laws and regulations; increases in costs and other liabilities associated with litigation, government investigations, audits or reviews; failure to complete, manage or integrate strategic transactions; risks associated with public health crises arising from large-scale medical emergencies, pandemics, natural disasters and other extreme events; failure to attract, develop, retain, and manage the succession of key employees and executives; our investment portfolio performance; impairment of our goodwill and intangible assets; failure to protect proprietary rights to our databases, software and related products; downgrades in our credit ratings; and our ability to obtain sufficient funds from our regulated subsidiaries or from external financings to fund our obligations, reinvest in our business, maintain our debt to total capital ratio at targeted levels, maintain our quarterly dividend payment cycle, or continue repurchasing shares of our common stock.

This above list is not exhaustive. We discuss these matters, and certain risks that may affect our business operations, financial condition and results of operations, more fully in our filings with the SEC, including our Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K. By their nature, forward-looking statements are not guarantees of future performance or results and are subject to risks, uncertainties and assumptions that are difficult to predict or quantify. Actual results may vary materially from expectations expressed or implied in, or incorporated by reference into, this prospectus supplement and the accompanying prospectus or any of our prior communications. You should not place undue reliance on forward-looking statements, which speak only as of the date they are made. We do not undertake to update or revise any forward-looking statements, except as required by law.

We intend to use the net proceeds from this offering for general corporate purposes, which may include refinancing short-term borrowings, which were incurred for general corporate and working capital purposes, or redeeming, repurchasing or repaying outstanding securities.

S-6

DESCRIPTION OF THE NOTES

In this section, the terms “we,” “our,” “us” and “UnitedHealth Group” refer solely to UnitedHealth Group Incorporated and not its subsidiaries.

The notes will be senior debt securities as described in the section captioned “Description of Debt Securities” in the accompanying prospectus. The following information concerning the notes supplements the information set forth in that section of the accompanying prospectus. It should be read together with the description of debt securities in the accompanying prospectus and the terms of the notes in the indenture, dated as of February 4, 2008, between us and U.S. Bank Trust Company, National Association, as trustee. The indenture is incorporated by reference into the registration statement which includes the accompanying prospectus. We will offer the 2027 notes, the 2029 notes, the 2031 notes, the 2034 notes, the 2054 notes and the 2064 notes as separate series under such indenture. Each series of notes also will be issued under and be subject to the terms of individual officers’ certificates and company orders pursuant to the indenture, which are incorporated by reference into the registration statement which includes the accompanying prospectus.

If any of the information set forth below is inconsistent with information in the accompanying prospectus, the information set forth below replaces the information in the accompanying prospectus.

The notes will be our senior, unsecured obligations and will rank equally in right of payment with all of our other unsecured and unsubordinated indebtedness from time to time outstanding. Our assets consist primarily of equity in our subsidiaries. As a result, our ability to make payments on the notes depends on our receipt of dividends, loan payments and other funds from our subsidiaries. In addition, if any of our subsidiaries becomes insolvent, the direct creditors of that subsidiary will have a prior claim on its assets. Our rights and the rights of our creditors, including your rights as an owner of the notes, will be subject to that prior claim, unless we also are a direct creditor of that subsidiary. This subordination of creditors of a parent company to prior claims of creditors of its subsidiaries is commonly referred to as “structural subordination.”

Title, Principal Amount, Maturity and Interest

The 2027 notes are designated as our 4.600% notes due April 15, 2027, the 2029 notes are designated as our 4.700% notes due April 15, 2029, the 2031 notes are designated as our 4.900% notes due April 15, 2031, the 2034 notes are designated as our 5.000% notes due April 15, 2034, the 2054 notes are designated as our 5.375% notes due April 15, 2054 and the 2064 notes are designated as our 5.500% notes due April 15, 2064.

The notes are initially limited in aggregate principal amount to $500,000,000 for the 2027 notes, $400,000,000 for the 2029 notes, $1,000,000,000 for the 2031 notes, $1,250,000,000 for the 2034 notes, $1,750,000,000 for the 2054 notes and $1,100,000,000 for the 2064 notes. We may at any time and from time to time, without the consent of the existing holders of the applicable series of notes, issue additional notes having the same ranking, interest rate, maturity date, redemption terms and other terms as any series of notes being offered under this prospectus supplement, except that if the additional notes are not fungible for U.S. federal income tax purposes with such series of notes being offered under this prospectus supplement, the additional notes will be issued under a separate CUSIP number. Any such additional notes, together with the notes having the same terms offered by this prospectus supplement, will constitute a single series of securities under the indenture. No additional notes may be issued if an event of default under the indenture has occurred with respect to the applicable series of notes. There is no limitation on the amount of other senior debt securities that we may issue under the indenture.

The 2027 notes will mature and become due and payable, together with any accrued and unpaid interest, on April 15, 2027. The 2029 notes will mature and become due and payable, together with any accrued and unpaid interest, on April 15, 2029. The 2031 notes will mature and become due and payable, together with any accrued and unpaid interest, on April 15, 2031. The 2034 notes will mature and become due and payable, together with

S-7

any accrued and unpaid interest, on April 15, 2034. The 2054 notes will mature and become due and payable, together with any accrued and unpaid interest, on April 15, 2054. The 2064 notes will mature and become due and payable, together with any accrued and unpaid interest, on April 15, 2064. We may redeem any series of notes at our option, either in whole or in part, before they mature. See “—Optional Redemption” below. If a change of control triggering event as described herein occurs, unless we have exercised our option to redeem all notes of an applicable series, we will be required to offer to repurchase such series of notes, in each case at the prices described in this prospectus supplement. See “—Change of Control Offer” below.

If any interest payment date, any maturity date or any date of repurchase or redemption date for any note falls on a day that is not a business day, we will postpone the payment of principal and interest to the next succeeding business day, but the payment made on such date will be treated as being made on the date that the payment was first due and the holders of the notes will not be entitled to any further interest or other payments with respect to such postponement. When we use the term business day, we mean any day except a Saturday, a Sunday or a day on which banking institutions in New York, New York or Minneapolis, Minnesota are authorized or required by law, regulation or executive order to close.

The interest payable by us on a note on any interest payment date, subject to certain exceptions, will be paid to the person in whose name the note is registered at the close of business on the applicable record date, whether or not a business day, immediately preceding the interest payment date.

In a Change of Control Offer, we will be required to offer payment in cash equal to 101% of the aggregate principal amount of notes repurchased, plus accrued and unpaid interest, if any, on the notes repurchased to, but not including, the date of repurchase (a “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event or, at our option, prior to any Change of Control, but after public announcement of the transaction that constitutes or may constitute the Change of Control, a notice will be transmitted to the holders of the 2027 notes, the 2029 notes, the 2031 notes, the 2034 notes, the 2054 notes or the 2064 notes, as the case may be, describing the transaction that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase such notes on the date specified in the applicable notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is transmitted (a “Change of Control Payment Date”). The notice will, if transmitted prior to the date of consummation of the Change of Control, state that the Change of Control Offer is conditioned on the Change of Control Triggering Event occurring on or prior to the applicable Change of Control Payment Date.

S-11

On each Change of Control Payment Date, we will, to the extent lawful:

We will not be required to make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by us and the third party purchases all notes properly tendered and not withdrawn under its offer. In addition, we will not repurchase any notes if there has occurred and is continuing on the Change of Control Payment Date an event of default under the indenture, other than a default in the payment of the Change of Control Payment upon a Change of Control Triggering Event.

We will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the notes, we will comply with those securities laws and regulations and will not be deemed to have breached our obligations under the Change of Control Offer provisions of the notes by virtue of any such conflict.

For purposes of the Change of Control Offer provisions of the notes, the following terms have the following meanings:

S-12

Certain Covenants

Merger, Consolidation or Sale of Assets

The indenture provides that we may not consolidate or merge with or into another company or sell or lease all or substantially all of our property or assets to another company unless:

S-13

Reports

The indenture provides that as long as any notes are outstanding, we will file with the trustee under the indenture, within 15 days after we 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 Section 15(d) of the Exchange Act. The filing of such reports, information and documents with the SEC will constitute filing of such reports, information and documents with the trustee; provided, however, that we will provide a physical or electronic copy thereof to the trustee promptly following a request therefor from the trustee.

Absence of Certain Covenants

We are not restricted by the indenture from, among other things, incurring, assuming or becoming liable for any type of debt or other obligations, from entering into sale-leaseback transactions, from paying dividends or making distributions on our capital stock or purchasing or redeeming our capital stock, making investments, selling or leasing less than substantially all of our assets or granting liens on our assets. The indenture does not require the maintenance of any financial ratios or specified levels of net worth or liquidity.

Trustee, Registrar and Paying Agent

U.S. Bank Trust Company, National Association, 60 Livingston Avenue, EP-MN-WS3C, St. Paul, Minnesota 55107-2292, serves as trustee under the indenture and has been appointed registrar and paying agent for the notes.

Defeasance

The notes are subject to legal defeasance and covenant defeasance as described in the section called “Description of Debt Securities—Defeasance Provisions” in the accompanying prospectus, except that the requirement to deliver an opinion of counsel to the trustee stating that after the 91st day following the deposit, the deposited funds will not be subject to the effect of any applicable bankruptcy law, will not be applicable to the notes.

Governing Law

The indenture and the notes are governed by, and will be construed in accordance with, New York law.

S-14

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

The following discussion summarizes the material United States federal income tax considerations of the purchase, ownership and disposition of the notes. The following discussion does not purport to be a complete analysis of all potential tax effects. The discussion is based upon the Internal Revenue Code of 1986, as amended, or the Code, United States Treasury Regulations, rulings and pronouncements of the Internal Revenue Service, or IRS, and judicial decisions in effect as of the date of this prospectus supplement, any of which subsequently may be changed, possibly retroactively, or interpreted differently by the IRS, so as to result in United States federal income tax consequences different from those discussed below.

The following discussion does not address all of the United States federal income tax consequences that may be relevant to a holder in light of such holder’s particular circumstances or to holders subject to special rules, such as financial institutions, insurance companies, dealers in securities or currencies, partnerships or other pass-through entities, expatriates, tax-exempt organizations, persons holding the notes as part of a straddle, hedge, conversion or constructive sale, or other integrated transaction for tax purposes, regulated investment companies, real estate investment trusts, traders in securities that elect to use a mark-to-market method of accounting for their securities, former citizens or residents of the United States, accrual method taxpayers that are required to recognize income for United States federal income tax purposes no later than when such income is taken into account in applicable financial statements, and “United States Holders” (as defined below) with a functional currency other than the U.S. dollar. In addition, this summary deals only with a note held as a “capital asset” within the meaning of Section 1221 of the Code by a beneficial owner who purchases the note on original issuance at the first price at which a substantial amount of the notes of that series are sold for cash to persons other than bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers, which we refer to as the “issue price.” Moreover, the effect of any alternative minimum tax, the Medicare tax on investment income, applicable state, local or foreign tax laws or of United States federal tax law other than income taxation is not discussed.

As used herein, “United States Holder” means a beneficial owner of notes who or that is:

As used herein, a “non-United States Holder” means a beneficial owner of notes, other than a partnership (or other entity treated as a partnership for United States federal income tax purposes), who or that is not a United States Holder.

If a partnership (including for this purpose any entity treated as a partnership for United States federal income tax purposes) is a beneficial owner of notes, then the tax treatment of a partner in the partnership generally will depend upon the status of the partner and upon the activities of the partnership. A holder of notes that is a partnership, and partners in such partnership, are urged to consult their tax advisors about the United States federal income tax consequences of purchasing, owning and disposing of the notes.

S-15

We have not sought and will not seek any rulings from the IRS with respect to the matters discussed below. There can be no assurance that the IRS will not take a different position concerning the tax consequences of the purchase, ownership or disposition of the notes or that any such position would not be sustained.

PERSONS CONSIDERING THE PURCHASE OF NOTES ARE URGED TO CONSULT THEIR INDEPENDENT TAX ADVISORS WITH REGARD TO THE APPLICATION OF THE TAX CONSEQUENCES DISCUSSED BELOW TO THEIR PARTICULAR SITUATIONS, AS WELL AS THE APPLICATION OF ANY STATE, LOCAL, FOREIGN OR OTHER TAX LAWS, INCLUDING GIFT AND ESTATE TAX LAWS.

Contingent Payments

In certain circumstances (see “Description of the Notes—Change of Control Offer”), we may be obligated to pay amounts on the notes that are in excess of stated interest on or principal of the notes. We intend to take the position that the likelihood that we will be required to make such payments is remote as of the issue date of the notes and therefore that these provisions do not cause the notes to be treated as “contingent payment debt instruments” within the meaning of the applicable Treasury Regulations. However, additional income will be recognized by a holder of notes if any such additional payment is made. Our position that the contingencies described above are remote is binding on a holder, unless the holder discloses in the proper manner to the IRS that it is taking a different position. If the IRS successfully challenged our position, then the notes could be treated as contingent payment debt instruments, in which case holders could be required to accrue interest income at a rate higher than the stated interest rate on the notes and to treat as ordinary income, rather than capital gain, any gain recognized on a sale, exchange, retirement or redemption of a note. The remainder of this discussion assumes that the notes will not be treated as contingent payment debt instruments.

United States Holders

Interest

Interest on the notes generally will be taxable to a United States Holder as ordinary income at the time that it is paid or accrued, in accordance with the United States Holder’s method of accounting for United States federal income tax purposes.

Sale, Retirement, Redemption or Other Taxable Disposition of a Note

A United States Holder of a note will recognize gain or loss upon the sale, retirement, redemption or other taxable disposition of such note in an amount equal to the difference between:

Any gain or loss recognized on a taxable disposition of such note generally will be capital gain or loss. Such capital gain or loss generally will be long-term capital gain or loss if the note has been held by the United States Holder for more than one year. Otherwise, such capital gain or loss will be a short-term capital gain or loss. In the case of certain non-corporate United States Holders (including individuals), long-term capital gain generally is subject to United States federal income taxation at preferential rates. The deductibility of capital losses is subject to certain limitations.

S-16

Non-United States Holders

Interest

Subject to the discussion of backup withholding and FATCA below, interest paid to a non-United States Holder of the notes will not be subject to United States federal withholding tax under the “portfolio interest exception,” provided that:

Interest paid to a non-United States Holder that does not qualify for the portfolio interest exception and that is not effectively connected to a United States trade or business (or, if required by an applicable income tax treaty, is not attributable to a United States permanent establishment) will be subject to United States federal withholding tax at a rate of 30%, unless a United States income tax treaty applies to reduce or eliminate withholding.

A non-United States Holder generally will be subject to tax in the same manner as a United States Holder with respect to interest, at regular graduated United States federal income tax rates, and such non-United States Holder generally will be exempt from the 30% withholding tax provided the certification requirements discussed below are satisfied, if such amounts are effectively connected with the conduct of a trade or business by the non-United States Holder in the United States and, if an applicable tax treaty requires, such interest is attributable to a United States permanent establishment maintained by the non-United States Holder. Such effectively connected income received by a non-United States Holder which is a corporation may be subject in some circumstances to an additional “branch profits tax” at a 30% rate or, if applicable, a lower treaty rate.

To claim the benefit of a lower treaty rate or to claim exemption from withholding because the income is effectively connected with a United States trade or business, the non-United States Holder must provide a properly executed IRS Form W-8BEN or W-8BEN-E, as applicable, or a suitable substitute form claiming an exemption from or reduction in withholding under the benefit of an applicable income tax treaty, or IRS Form W-8ECI or a suitable substitute form stating that interest paid on the notes is not subject to withholding tax because it is effectively connected with the non-United States Holder’s conduct of a trade or business in the United States, as applicable. Such certificate must contain, among other information, the name and address of the non-United States Holder. These forms may be required to be periodically updated. In some circumstances, in lieu of providing an IRS Form W-8BEN or W-8BEN-E, as applicable, the non-United States Holder may provide certain documentary evidence issued by foreign governmental authorities to prove residence in a foreign country in order to claim treaty benefits.

Special procedures relating to United States withholding taxes are provided under applicable Treasury Regulations for payments through qualified intermediaries or certain financial institutions that hold customers’ securities in the ordinary course of their trade or business.

Non-United States Holders are urged to consult their tax advisors regarding applicable income tax treaties, which may provide different rules.

S-17

Sale of Notes

Subject to the discussion of backup withholding and FATCA below, a non-United States Holder generally will not be subject to United States federal income tax or withholding tax on gain realized on the sale or exchange of a note unless:

A non-United States Holder described in clause (2) above generally will be subject to tax with respect to such gain in the same manner as a United States Holder. In some circumstances, a non-United States Holder which is a corporation will be subject to an additional “branch profits tax” at a 30% rate or, if applicable, a lower treaty rate on such income. If a non-United States Holder is an individual described in clause (1) above, such holder will be subject to a flat 30% tax on the gain derived from the sale or exchange, which may be offset by United States source capital losses, even though such holder is not considered a resident of the United States. Amounts attributable to accrued but unpaid stated interest realized on the sale or exchange of a note will be subject to the rules applicable to interest, as described in “—Non-United States Holders—Interest” above.

Information Reporting and Backup Withholding

Certain United States Holders may be subject to information reporting requirements on payments of principal and interest on a note and payments of the proceeds of the sale of a note, and backup withholding tax at the applicable rate may apply to such payments, if the United States Holder:

A non-United States Holder generally is not subject to backup withholding on payment of interest if it certifies as to its status as a non-United States Holder under penalties of perjury in the manner described in “—Non-United States Holders—Interest” above or otherwise establishes an exemption, provided that the applicable withholding agent does not have actual knowledge or reason to know that the non-United States Holder is a United States person or that the conditions of any other exemptions are not, in fact, satisfied. However, information reporting requirements will apply to payments of interest to non-United States Holders. Copies of these information returns also may be made available under the provisions of a specific treaty or agreement to the tax authorities of the country in which the non-United States Holder resides.

The payment of the proceeds from the disposition of notes to or through the United States office of any broker, United States or foreign, will be subject to information reporting and possible backup withholding unless the owner certifies as to its non-United States status under penalties of perjury in the manner described in “—Non-United States Holders—Interest” above or otherwise establishes an exemption, and the broker does not have actual knowledge or reason to know that the non-United States Holder is a United States person or that the conditions of any other exemption are not, in fact, satisfied.

The payment of the proceeds from the disposition of a note to or through a non-United States office of a non-United States broker that is not a “United States related person” generally will not be subject to information reporting or backup withholding. For this purpose, a “United States related person” is:

S-18

In the case of the payment of proceeds from the disposition of notes to or through a non-United States office of a broker that is either a United States person or a United States related person, the payment may be subject to information reporting unless the broker has documentary evidence in its files that the owner is a non-United States Holder and the broker has no knowledge or reason to know to the contrary. Backup withholding will not apply to payments made through foreign offices of a broker that is a United States person or a United States related person (absent actual knowledge that the payee is a United States person).

Any amounts withheld under the backup withholding rules from a payment to a holder will be allowed as a refund or a credit against such holder’s United States federal income tax liability, provided that the requisite procedures are followed.

Holders of notes are urged to consult their tax advisors regarding their qualification for exemption from backup withholding and the procedure for obtaining such an exemption, if applicable.

Foreign Account Tax Compliance Act

Under the Foreign Account Tax Compliance Act, or FATCA, a 30% withholding tax may be imposed on payments of interest on, and, subject to the proposed Treasury Regulations discussed below, payments of gross proceeds from the sale or other disposition of notes made to a “foreign financial institution” or a “non-financial foreign entity” (in each case, as defined in the Code), regardless of whether such foreign institution or entity is a beneficial owner or an intermediary, unless:

If the payee is a foreign financial institution and is subject to the diligence and reporting requirements described in clause (1) above, it must enter into an agreement with the U.S. Department of the Treasury requiring, among other matters, that it undertake to identify accounts held by certain “United States persons” or “United States owned foreign entities” (in each case, as defined in the Code), annually report certain information about such accounts and withhold 30% on certain payments to non-compliant foreign financial institutions and certain other account holders. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.

While withholding under FATCA generally would have applied to payments of gross proceeds from the sale or other disposition of a note on or after January 1, 2019, proposed Treasury Regulations eliminate FATCA withholding on payments of gross proceeds entirely. Taxpayers generally may rely on these proposed Treasury Regulations until final Treasury Regulations are issued. If an interest payment is subject both to withholding under FATCA and to the withholding tax discussed above under “—Non-United States Holders—Interest,” the withholding under FATCA may be credited against, and therefore reduce, such other withholding tax. Prospective investors should consult their tax advisors regarding the consequences and application of the rules under FATCA.

S-19

UNDERWRITING

Under the terms and subject to the conditions contained in an underwriting agreement, BofA Securities, Inc., Barclays Capital Inc., J.P. Morgan Securities LLC and Mizuho Securities USA LLC, as representatives of the underwriters named below, have severally, and not jointly, agreed to purchase, and we have agreed to sell to each underwriter named below, the following respective principal amounts of the notes:

The underwriting agreement provides that the underwriters are obligated to purchase all of the notes if any are purchased. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may be increased or the offering of notes may be terminated.

Notes sold by the underwriters to the public will initially be offered at the public offering prices set forth on the cover page of this prospectus supplement. Any notes sold by the underwriters to securities dealers may be sold at a discount from the public offering price of up to 0.15% of the principal amount of each 2027 note, up to 0.20% of the principal amount of each 2029 note, up to 0.20% of the principal amount of each 2031 note, up to 0.25% of the principal amount of each 2034 note, up to 0.45% of the principal amount of each 2054 note and up to 0.45% of the principal amount of each 2064 note. Any such securities dealers may resell any notes purchased from the underwriters to certain other brokers or dealers at a discount from the public offering price of up to 0.10% of the principal amount of each 2027 note, up to 0.125% of the principal amount of each 2029 note, up to 0.15% of the principal amount of each 2031 note, up to 0.15% of the principal amount of each 2034 note, up to

S-20

0.30% of the principal amount of each 2054 note and up to 0.30% of the principal amount of each 2064 note. After the initial offering of the notes, the underwriters may change the offering prices.

We have agreed to indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments the 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 an officers’ certificate 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 expenses of the offering, not including the underwriting discounts, are estimated to be approximately $9,175,000 and are payable by us.

New Note Issues

The notes are new issues of securities with no established trading markets for the notes. We do not intend to apply for listing of the notes on any securities exchange or for inclusion of the notes in any automated dealer quotation system. We have been advised by certain of the underwriters that they presently intend to make markets in the notes after completion of the offering. However, such underwriters are under no obligation to do so and may discontinue any market-making activities at any time without any notice. We cannot ensure the liquidity of the 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 price and liquidity of the notes may be adversely affected.

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 an underwriter creates a short position in the notes in connection with the offering, i.e., if it sells more notes than are referred to on the cover page of this prospectus supplement, the underwriter may reduce that short position 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.

Neither we nor the underwriters make 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 the underwriters make any representation that the underwriters will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters 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.

Other Relationships

The underwriters and their respective 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 underwriters and their affiliates have engaged in, and may in the future engage in, financial advisory, commercial and investment banking services, hedging services and other commercial dealings in the ordinary course

S-21

of business with us or our affiliates, including dealers in our commercial paper program, brokers in our share repurchase program, lenders under our revolving credit facilities and advisors in connection with strategic transactions. They have received or may in the future receive customary fees and commissions for these transactions.

U.S. Bancorp Investments, Inc., one of the underwriters, is an affiliate of the trustee under the indenture. Additionally, Associated Investment Services, Inc. (AIS), a Financial Industry Regulatory Authority member, an indirect, wholly owned subsidiary of Associated Banc-Corp, is being paid a referral fee by Samuel A. Ramirez & Company, Inc.

In addition, in the ordinary course of their business activities, the underwriters and their affiliates may make or hold a broad array of investments, including serving as counterparties to certain derivative and hedging arrangements, and actively trade debt and equity securities (or related derivative securities), currencies, commodities, credit default swaps and other 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 may have a lending relationship with us and may hedge such credit exposure to us, including by entering into transactions that consist of either the purchase of credit default swaps or the creation of short positions in our securities (including 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 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 or short positions in such securities and instruments.

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

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

DESCRIPTION OF DEBT SECURITIES

In this section, the terms “we,” “our,” “us” and “UnitedHealth Group” refer solely to UnitedHealth Group Incorporated and not its subsidiaries.

We will issue the debt securities under the indenture dated as of February 4, 2008 between us and U.S. Bank Trust Company, National Association, as the trustee. We refer to this indenture, as supplemented and amended, as the “indenture” and to the trustee under the indenture as the “trustee.” The indenture has been qualified under the Trust Indenture Act of 1939. The indenture has been filed as an exhibit to the registration statement. References to “debt securities” are references to the debt securities that may be issued under the indenture.

This section describes the general terms and provisions of the indenture and the debt securities that may be offered by this prospectus. The prospectus supplement will describe the specific terms of the series of the debt securities offered under that prospectus supplement and any general terms outlined in this section that will not apply to those debt securities. Because this is only a summary, it does not contain all of the details found in the full text of the indenture and the debt securities. If you would like additional information, you should read the indenture. The following summary is qualified in its entirety by the provisions of the indenture.

General

The debt securities may be issued from time to time in one or more series. Debt securities issued under the indenture will be issued as part of a series that we will have established pursuant to the indenture. Any series of debt securities may have terms that are different from other series. The indenture does not limit the aggregate principal amount of debt securities which we may issue under the indenture.

We are not obligated to issue all of the debt securities of one or more series at the same time and, unless otherwise provided in the prospectus supplement, we may issue additional debt securities of a series without the consent of the holders of the debt securities of that series. Additional debt securities of a particular series will have the same terms and conditions as outstanding debt securities of such series, except for the date of original issuance, the offering price and, in some cases, the first interest payment date, and will be consolidated with, and form a single series with, such outstanding debt securities. The indenture permits additional debt securities of a series to be issued with original issue discount without the consent of the holders of the debt securities of that series. To the extent the terms of any series of debt securities permit such an issuance, any conditions and material U.S. federal income tax consequences applicable to that issuance will be described in the applicable prospectus supplement.

Unless provided otherwise in the applicable prospectus supplement, the debt securities will be issued only in registered form, without coupons, in denominations of $1,000 each or multiples of $1,000.

Debt securities may be issued in the form of one or more global securities, as described below under the heading “— Book-Entry Issuance, Clearing and Settlement.”

There will be no service charge for any registration of transfer or exchange of the debt securities, but we may require you to pay any tax or other governmental charge payable in connection with a transfer or exchange of the debt securities.

Unless the applicable prospectus supplement states otherwise, we will pay interest on the debt securities to the person listed as the owner of the debt securities in the security register at the close of business on the regular record date for the applicable interest payment date. Defaulted interest, however, may be paid to holders as of special record dates established in the manner set forth in the indenture.

All moneys deposited with the trustee or a paying agent, or then held by us, in trust for the payment of the principal of or any premium or interest on any debt securities which remain unclaimed at the end of two years

6

after the principal, premium or interest has become due and payable will be paid to us on our request, and you may thereafter, as an unsecured general creditor, look only to us for payment thereof.

Ranking

The senior debt securities offered by this prospectus will be general obligations that:

The subordinated debt securities offered by this prospectus will be general obligations that:

A substantial portion of our assets are owned through our subsidiaries, many of which have significant liabilities of their own which will be structurally senior to the debt securities. Therefore, our rights and the rights of our creditors, including holders of debt securities, to participate in the assets of any subsidiary upon any such subsidiary’s liquidation will be subject to the prior claims of the subsidiary’s creditors.

Terms

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

7

Redemption

The prospectus supplement will describe the provisions, if any, for redemption of the debt securities at our option.

Unless otherwise described in the prospectus supplement, we are not required to make mandatory redemption or sinking fund payments. The prospectus supplement will describe the provisions, if any, regarding sinking fund provisions.

The indenture provides that, with respect to sinking fund payments, we may:

in each case, in satisfaction of all or any part of any required sinking fund payment with respect to the debt securities, with similar terms, of the same series.

The indenture provides that, if less than all of the debt securities with similar terms of any series are to be redeemed at any time, selection of the debt securities for redemption will be made by the trustee on:

8

Portions of the debt securities selected for redemption shall be in amounts of $1,000 or in multiples of $1,000, except that if all of the debt securities of a holder are to be redeemed, the entire outstanding amount shall be redeemed.

Notices of redemption shall be mailed by first class mail at least 30 but not more than 60 days before the redemption date to each holder of debt securities to be redeemed at its registered address. If any debt security is to be redeemed in part only, the notice of redemption that relates to the debt security shall state the portion of the principal amount of the debt security to be redeemed. A new debt security, with similar terms and of the same series, in principal amount equal to the unredeemed portion of the original debt security, if any, will be issued in the name of the holder of the original debt security upon cancellation of the original debt security.

On and after the redemption date, interest will no longer accrue on the debt securities or any part of the debt securities called for redemption unless we default in the payment of the redemption price and accrued interest.

Conversion and Exchange

Unless otherwise described in the prospectus supplement, the debt securities are not convertible or exchangeable for common stock of UnitedHealth Group.

Certain Covenants

Merger, Consolidation, or Sale of Assets. The indenture provides that we may not consolidate or merge with or into another company or sell or lease all or substantially all of our property or assets to another company unless:

Reports. The indenture provides that as long as any debt securities are outstanding, we will file with the trustee, within 15 days after we 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 Section 15(d) of the Exchange Act. The filing of such reports, information and documents with the SEC will constitute filing of such reports, information and documents with the trustee; provided, however, that we will provide a physical or electronic copy thereof to the trustee promptly following a request therefor from the trustee.

Absence of Certain Covenants. The prospectus supplement will specify any additional restrictive covenants applicable to the debt securities. Except as may be described in the applicable prospectus supplement, we are not restricted by the indenture from, among other things, incurring, assuming or becoming liable for any type of debt or other obligations, from entering into sale-leaseback transactions, from paying dividends or making distributions on our capital stock or purchasing or redeeming our capital stock, making investments, selling or leasing less than substantially all of our assets or granting liens on our assets. The indenture does not require the maintenance of any financial ratios or specified levels of net worth or liquidity.

Events of Default; Remedies

The indenture provides that any of the following constitutes an event of default with respect to the debt securities of any series:

9

If an event of default under the indenture occurs on outstanding debt securities of a particular series and continues, the trustee or holders of at least 25% in principal amount of that series of debt securities may declare the principal amount of all debt securities in that series to be due and payable immediately. Under certain circumstances, holders of a majority in principal amount of the debt securities of a series may rescind a declaration.

Notwithstanding the foregoing, in the case of an event of default arising from certain events of bankruptcy or insolvency with respect to UnitedHealth Group, all principal, premium, if any, and interest on outstanding debt securities will become due and payable without further action or notice.

Except in the case of a default in payment, the trustee may withhold notice if it determines that withholding notice is in the interests of the holders of the debt securities.

The holders of a majority in principal amount of the outstanding debt securities of any series may waive the rights of all holders with respect to circumstances that constitute an event of default or will constitute an event of default with notice and the passage of time. The holders must waive the rights in a written notice to both us and the trustee. Holders of a majority in principal amount of the debt securities, however, may not waive the rights of all holders relating to these events if they involve a default in payment obligations or a provision of the indenture that cannot be modified or amended without the consent of each holder of debt securities of such series affected. Any waivers that are given will not apply to any subsequent default and will not impair any future rights if those types of defaults occur.

Holders of a majority in principal amount of the outstanding debt securities of any series may direct the time, method and place of conducting any proceeding for any remedy available to, or exercising any trust or power conferred on, the trustee with respect to the series. However, the trustee may refuse to follow any direction that conflicts with law or the indenture. The trustee may take any other action which it deems proper which is not inconsistent with any direction given.

A holder of any debt security of any series will have the right to institute any proceeding with respect to the indenture or for any remedy only if:

10

The indenture also provides that a holder may not use the indenture to prejudice the rights of another holder or to obtain a preference or priority over another holder.

We are required to deliver to the trustee an annual certificate, signed by an officer, stating that, to such officer’s knowledge, we are not in default in the performance or observance of the indenture, or, if a default or event of default has occurred, containing a description of any default or event of default.

Certain Provisions Applicable to Trustee

The indenture provides that prior to an event of default under the indenture, the trustee is required to perform only the specific duties stated in the indenture. Upon an event of default under the indenture, the trustee must exercise the same degree of care as a prudent individual would exercise in the conduct of his or her own affairs. The trustee may in good faith conclusively rely, as to the truth of the statements and the correctness of the opinions expressed in any certificates or opinions furnished to the trustee which conform to the requirements of the indenture, upon the certificates and opinions. However, the trustee is required to examine the certificates and opinions to determine whether or not they conform to the requirements of the indenture.

The indenture provides that the trustee may resign at any time or may be removed by the holders of a majority in principal amount of the outstanding debt securities of a series with respect to that series or by us under certain circumstances by notice delivered to the trustee and us. The indenture also provides that the trustee must resign if it ceases to meet certain qualifications set forth in the indenture. In the event of a trustee’s resignation or removal, we or, if we fail to act, the holders of a majority in principal amount of the outstanding debt securities of the applicable series may appoint a successor trustee.

Defeasance Provisions

The indenture includes provisions allowing defeasance of the debt securities. Defeasance means that we may discharge our entire indebtedness under an agreement, in this case the indenture, if specific acts are performed. Specifically, the indenture provides that:

provided that the following conditions shall have been satisfied:

11

Modification and Amendment of Indenture

Under the indenture, our rights and obligations and the rights of the holders of debt securities may be changed. Certain changes require the consent of the holders of not less than a majority in aggregate principal amount of the outstanding debt securities of each series of debt securities affected by the modification or amendment. The following changes, however, may not be made without the consent of each holder of the outstanding debt securities:

Governing Law

The indenture is governed by and will be construed in accordance with New York law.

Book-Entry Issuance, Clearing and Settlement

Unless otherwise provided in the applicable prospectus supplement, the debt securities of each series offered by means of this prospectus will be issued in the form of one or more fully registered global securities, without coupons, each of which we refer to as a “global security.” Each such global security will be registered in the name of Cede & Co., as nominee of The Depository Trust Company, or DTC, another nominee of DTC or a successor of DTC or its nominee. So long as Cede & Co., as the nominee of DTC, is the sole registered owner of any global security, Cede & Co. for all purposes will be considered the sole holder of that global security. Except under the limited circumstances described in this prospectus or in the applicable prospectus supplement, owners of beneficial interests in a global security will not be entitled to have certificates registered in their names, will not receive delivery of physical certificates, and will not be considered the holders thereof.

DTC has advised us as follows: DTC 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 was created to hold securities for its participants and to facilitate the clearance and settlement of securities

12

transactions, such as transfers and pledges, among participants in deposited securities through electronic book-entry charges to accounts of its participants, thereby eliminating the need for physical movement of securities certificates. The rules applicable to DTC and its participants are on file with the SEC.

Beneficial owners that are DTC participants may hold their interest in a global security directly through DTC. Beneficial owners that are not DTC participants may hold their interest in a global security indirectly through direct participants of DTC or through certain clearing systems, banks, brokers, dealers, trust companies and other parties that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly, and have indirect access to DTC (each such entity an “indirect participant”), including Euroclear Bank S.A./ N.V. and Clearstream Banking S.A. Unless and until definitive debt securities are issued, all references to actions by holders of debt securities issued in global form refer to actions taken by DTC upon instructions from its participants, and all references herein to payments and notices to the holders refer to payments and notices to DTC or its nominee, as the registered holder of the offered debt securities.

Beneficial interests in a global security will be shown on, and transfers of beneficial interests in the global security will be made only through, records maintained by DTC and its participants, both direct and indirect. When you purchase debt securities through the DTC system, the purchases must be made by or through a direct DTC participant, which will receive credit for the debt securities in its account on DTC’s records. When you actually purchase the debt securities, you will become their beneficial owner. Your ownership interest will be recorded only on the direct or indirect DTC participants’ records. DTC will have no knowledge of your individual ownership of the debt securities. DTC’s records will show only the identity of the direct DTC participants and the amount of the debt securities held by or through them.

You will not receive a written confirmation of your purchase or sale or any periodic account statement directly from DTC. You should instead receive these confirmations and account statements from the direct or indirect DTC participant through which you purchase the debt securities. The direct or indirect DTC participants are responsible for keeping accurate account of the holdings of their customers. The trustee will wire payments on the securities to the DTC nominee that is the registered holder of the debt securities. We and the trustee will treat DTC or its nominee as the owner of each global security for all purposes. Accordingly, none of us, the trustee and any paying agent will have any direct responsibility or liability to pay amounts due on a global security to you or any other beneficial owners in that global security. Any redemption notices will be sent by us directly to DTC or its nominee, which will, in turn, inform the direct DTC participants, which will then contact beneficial owners holding interests in the debt securities through them.

Under the rules, regulations and procedures creating and affecting DTC and its operations, DTC is required to make book-entry transfers between direct DTC participants on whose behalf it acts with respect to the debt securities and is required to receive and transmit distributions of principal of and interest on the debt securities. Direct and indirect DTC participants with which investors have accounts with respect to the debt securities similarly are required to make book-entry transfers and receive and transmit payments on behalf of their respective investors.

As DTC can act only on behalf of direct DTC participants, who in turn act on behalf of indirect DTC participants and certain banks, the ability of a beneficial owner of an interest in a debt security held in DTC to transfer or pledge that interest to persons or entities that do not participate in the DTC system, or otherwise take actions in respect of that interest, may be affected by the lack of a physical certificate representing that interest. The laws of some states of the United States require that certain persons take physical delivery of securities in definitive form in order to transfer or perfect a security interest in those securities. Consequently, the ability to transfer beneficial interests in a debt security held in DTC to those persons may be limited.

DTC has advised us that it will take any action permitted to be taken by a holder of debt securities under the terms and conditions of the debt securities (including, without limitation, the presentation of debt securities for exchange) only at the direction of one or more of the direct DTC participants to whose accounts with DTC

13

interests in the relevant debt securities are credited, and only in respect of the portion of the aggregate principal amount of the debt securities as to which that direct DTC participant or those direct DTC participants has or have given the direction. However, in certain circumstances described below, DTC will exchange the global securities held by it for certificated securities, which it will distribute to the direct DTC participants.

It is DTC’s current practice, upon receipt of any payment of distributions or liquidation amounts, to proportionately credit direct DTC participants’ accounts on the payment date based on their holdings of the relevant securities. In addition, it is DTC’s current practice to pass through any consenting or voting rights to such direct DTC participants by using an omnibus proxy. Consequently, those direct DTC participants should, in turn, based on customary practices, make payments to and solicit votes from beneficial owners of debt securities who have accounts directly with them. Payments to you with respect to your beneficial interest in any debt securities will be the responsibility of the direct and indirect DTC participants with which you have an account, and not of DTC, the trustee or UnitedHealth Group.

DTC may discontinue providing its services as securities depositary with respect to debt securities at any time by giving us reasonable notice.

Debt securities represented by one or more global securities will be exchangeable for definitive debt securities, that is, certificated debt securities, with the same terms in authorized denominations only if:

If a global security is exchanged for definitive debt securities, the trustee will keep the registration books for the debt securities at its corporate office and follow customary practices and procedures regarding those certificated debt securities.

DESCRIPTION OF COMMON STOCK

We have registered our common stock, par value $0.01 per share, under Section 12 of the Exchange Act.

We are currently authorized under our charter to issue up to 3,000,000,000 shares of the common stock. As of January 31, 2023, 932,846,602 shares of our common stock were outstanding. Each share of our common stock has the same relative rights and is identical in all respects to each other share of our common stock.

Holders of shares of our common stock are entitled to one vote per share on all matters to be voted on by shareholders. Except with respect to the election of directors, each matter submitted to a vote of our shareholders will be decided by the affirmative vote of the holders of a majority of the voting power of the shares present and entitled to vote on that matter. Each director is elected by the vote of the majority of the votes cast with respect to such director, unless the number of director nominees exceeds the number of directors to be elected, in which event directors are elected by a plurality of the votes present and entitled to vote on the election of directors. Our shareholders are not entitled to cumulate their votes for the election of directors.

Our common stock is not redeemable, has no subscription or conversion rights and does not entitle the holders thereof to any preemptive rights to subscribe for any shares of any class or series of our capital stock, whether now or hereafter authorized, or for any obligations convertible into shares of any class or series of our capital stock, whether now or hereafter authorized. The holders of our common stock are entitled to receive such dividends, if any, as may be declared by our board of directors in its discretion out of funds legally available therefor. Subject to the rights of any preferred stock outstanding, upon liquidation or dissolution of UnitedHealth Group, the holders of our common stock are entitled to receive on a pro rata basis all assets remaining for distribution to shareholders.

Our charter and bylaws contain provisions that could have the effect of delaying or deferring a change in control of our company, including provisions that:

Our common stock is listed on the New York Stock Exchange and trades under the symbol “UNH.” EQ Shareowner Services is the transfer agent and registrar for our common stock.

DESCRIPTION OF WARRANTS

We may issue warrants, in one or more series, for the purchase of debt securities, shares of our preferred stock or shares of our common stock. Warrants may be issued independently or together with our debt securities, preferred stock or 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. In addition to this summary, you should refer to the relevant prospectus supplement and the detailed provisions of the relevant warrant agreement for complete terms of the warrants and the warrant agreement. Unless otherwise specified in a prospectus supplement accompanying this prospectus, each warrant agreement will be between us and a banking institution organized under the laws of the United States or a state thereof as warrant agent. In connection with an offering of our warrants, a form of warrant agreement will be filed with the SEC as an exhibit to the registration statement by post-effective amendment or to a Current Report on Form 8-K.

Warrants will be evidenced by warrant certificates. Unless otherwise specified in the applicable prospectus supplement, the warrant certificates may be traded separately from the debt securities, preferred stock or common stock, if any, with which the warrant certificates were issued. Warrant certificates may be exchanged for new warrant certificates of different denominations at the office of an agent that we will appoint. Until a warrant is exercised, the holder of a warrant will not have any of the rights of a holder of our debt securities, preferred stock or common stock and will not be entitled to any payments on any debt securities, preferred stock or common stock issuable upon exercise of the warrants.

The prospectus supplement relating to a particular series of warrants to issue debt securities, preferred stock or common stock will describe the terms of those warrants, including the following, where applicable:

DESCRIPTION OF GUARANTEES

Any guarantees that we issue from time to time for the benefit of holders of specified underlying securities will include the following terms and conditions, as well as any additional terms specified in the accompanying prospectus supplement.

A guarantee will provide that we unconditionally guarantee the payment of the principal, interest (if any), premium (if any) and all other amounts due under the applicable underlying securities when the same will become due and payable, whether at maturity, pursuant to mandatory or optional prepayments, by acceleration or otherwise, in each case after any applicable grace periods or notice requirements, according to the terms of the applicable underlying securities. Any guarantee will be unconditional irrespective of the validity or enforceability of the applicable underlying security, any change or amendment thereto or any other circumstances that may otherwise constitute a legal or equitable discharge or defense of a guarantor. Unless otherwise provided in the accompanying prospectus supplement, we will not waive presentment or demand of payment or notice with respect to the applicable underlying security.

We will be subrogated to all rights of the holders of the applicable underlying securities in respect of any amounts paid by us pursuant to the provisions of a guarantee, except to the extent otherwise stated in a prospectus supplement. The guarantees will continue to be effective or reinstated, as the case may be, if at any time any payment made by the issuer of the applicable underlying security is rescinded or must otherwise be returned upon the insolvency, bankruptcy or reorganization of UnitedHealth Group, the issuer of the applicable underlying security or otherwise.

PLAN OF DISTRIBUTION

We may sell the securities:

We will describe in the applicable prospectus supplement the particular terms of the offering of securities, including the following:

If we use underwriters in the sale, such underwriters will acquire the securities for their own account. The underwriters may resell the securities in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale.

The securities may be offered to the public either through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. The obligations of the underwriters to purchase the securities will be subject to specified conditions. The underwriters will be obligated to purchase all the securities offered if any of the securities are purchased. The underwriters may change from time to time any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers.

We may sell offered securities through agents designated by us from time to time. Any agent involved in the offer or sale of the securities for which this prospectus is delivered will be named, and any commissions payable by us to that agent will be set forth, in the applicable prospectus supplement. Unless indicated in the prospectus supplement, the agents will have agreed to use their reasonable best efforts to solicit purchases for the period of their appointment.

We also may sell offered securities directly to one or more purchasers.

We may have agreements with the underwriters, dealers and agents to indemnify them against certain civil liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute with respect to payments which the underwriters, dealers or agents may be required to make relating to those liabilities.

Unless indicated in the applicable prospectus supplement, we do not expect to list the securities on a securities exchange.

To facilitate the offering of the securities, any underwriters, dealers or agents, as the case may be, involved in the offering of such securities may engage in transactions that stabilize, maintain or otherwise affect the price of such securities or any other securities the prices of which may be used to determine payments on such securities.
