Prospectus Supplement

(to Prospectus dated January 22, 2021)

Assurant, Inc.

$175,000,000 6.100% Senior Notes due 2026

Assurant, Inc. is offering $175,000,000 principal amount of 6.100% senior notes due 2026 (the “Notes”). We will pay interest on the Notes semi-annually on February 27 and August 27 of each year, beginning on August 27, 2023. The Notes will mature on February 27, 2026.

Prior to January 27, 2026 (the date that is one month prior to their maturity date) (the “Par Call Date”)), we may redeem the Notes at our option, in whole or in part, at any time and from time to time, at the applicable redemption price described in “Description of the Notes—Optional Redemption.” On or after the Par Call Date, we may redeem the Notes at our option, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to, but excluding, the redemption date. See “Description of the Notes—Optional Redemption.”

The Notes will be our senior unsecured obligations and will rank equally in right of payment with all of our other senior unsecured indebtedness from time to time outstanding, and senior in right of payment to all existing and future subordinated indebtedness. The Notes will be issued in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

We intend to use the net proceeds from this offering (and available cash on hand) to redeem a portion of the $225.0 million outstanding aggregate principal amount of our 4.20% Senior Notes due 2023 (the “2023 Notes”) and to pay related premiums, fees and expenses. See “Use of Proceeds.”

See “Risk Factors” on page S-7 of this prospectus supplement and page 5 of the accompanying prospectus to read about factors you should consider before investing in the Notes.

The Notes will not be listed on any national securities exchange or included in any automated dealer quotation system. Currently, there is no public market for the Notes. Neither the Securities and Exchange Commission (the “SEC”) nor any other regulatory body has approved or disapproved of these securities or passed upon the accuracy or adequacy of this prospectus supplement or the accompanying prospectus. Any representation to the contrary is a criminal offense.

The underwriters expect to deliver the Notes to purchasers through the book-entry delivery system of The Depository Trust Company for the accounts of its participants, including Clearstream Banking, S.A., and Euroclear Bank SA/NV, on or about February 28, 2023, against payment in immediately available funds.

RISK FACTORS

Investing in the Notes involves risks. In considering whether you should invest in the Notes, you should consider all of the information we have included or incorporated by reference in this prospectus supplement and the accompanying prospectus. In particular, you should carefully consider the risk factors described below, as well as in our Annual Report on Form 10-K for the year ended December 31, 2022 under “Item 1A. Risk Factors.” You should also read all other information contained in or incorporated by reference in this prospectus supplement and the accompanying prospectus before deciding to invest in the Notes. If any of the risks actually occur, they may materially harm our business, financial condition, operating results or cash flow. Additional risks and uncertainties that are not yet identified or that we think are immaterial may also materially harm our business, financial condition, operating results or cash flow and could result in a complete or partial loss of your investment.

This prospectus supplement, the accompanying prospectus and the incorporated documents also contain forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks faced by us as described in this prospectus supplement and the documents incorporated by reference in this prospectus supplement and the accompanying prospectus. For more information see “Forward-Looking Information” in the accompanying prospectus and “Forward-Looking Statements” in this prospectus supplement.

The Notes are effectively subordinated to any debt of Assurant that is secured.

The Notes are our unsecured obligations, and will be effectively subordinated to any of our future secured indebtedness to the extent of the value of the assets that secure that indebtedness. The effect of this subordination is that if Assurant is involved in a bankruptcy, liquidation, dissolution, reorganization or similar proceeding, or upon a default in payment on, or the acceleration of, any secured debt of Assurant, the assets that secure such debt will be available to pay obligations on the Notes only after all such debt has been paid in full from the assets securing such debt. Holders of the Notes will participate in any remaining assets ratably with all of the other unsecured and unsubordinated creditors of Assurant. We may not have sufficient assets remaining to pay amounts due on any or all of the Notes then outstanding. See “Description of the Notes.”

We could incur significant additional indebtedness in the future, which could impair our ability to make payments under the Notes.

As of December 31, 2022, we had total outstanding indebtedness of approximately $2.1 billion and an additional $499.8 million of available borrowing under our revolving credit facility, all of which would be unsecured indebtedness. See “Capitalization” for more information. In addition, the Notes and the senior notes indenture governing the Notes generally do not contain restrictive covenants, such as a limitation on the payments of dividends, the incurrence of indebtedness or the issuance or repurchase of securities by us. Thus, we may incur substantial additional indebtedness in the future, which could affect our ability to make payments under the Notes.

Holders of the Notes have only limited rights of acceleration.

Holders of the Notes may accelerate payment of the principal and accrued and unpaid interest on the Notes only upon the occurrence and continuation of an event of default. An event of default under the Notes is generally limited to payment defaults, breaches of specific covenants and specific events of bankruptcy, insolvency and reorganization relating to us.

If an active trading market does not develop for the Notes, you may not be able to resell your Notes.

There is no established trading market for the Notes. We cannot assure you that an active market for the Notes will develop or be sustained or that holders of the Notes will be able to sell their Notes at favorable prices

S-7

or at all. Although the underwriters have indicated to us that they intend to make a market for the Notes, as permitted by applicable laws and regulations, they are not obligated to do so and may discontinue any such market-making at any time without notice. Accordingly, no assurance can be given as to the liquidity of, or trading markets for, the Notes. We do not intend to list the Notes on any securities exchange or include them on any automated quotation system. The liquidity of any market for the Notes will depend upon various factors, including:

In addition, the liquidity of the trading market for the Notes, and the market price quoted for the Notes, may be adversely affected by changes in the overall market for fixed income securities generally. As a result, an active trading market may not develop for the Notes. If no active trading market develops, you may not be able to resell your Notes at a price that reflects accrued and unpaid interest, if at all.

S-8

USE OF PROCEEDS

The net proceeds from this offering are estimated to be approximately $173.1 million, after deducting underwriting discounts and commissions and estimated offering expenses payable by us.

We intend to use the net proceeds from this offering (and available cash on hand) to redeem a portion of the $225.0 million outstanding aggregate principal amount of our 2023 Notes and to pay related premiums, fees and expenses. Prior to such application of the proceeds described above, we may hold the proceeds in cash, invest the proceeds, repay short-term indebtedness or otherwise utilize such proceeds.

This prospectus supplement does not constitute a notice of redemption for the 2023 Notes, which will be made in accordance with the indenture governing the 2023 Notes.

CAPITALIZATION

The following table sets forth our consolidated capitalization at December 31, 2022:

S-10

DESCRIPTION OF THE NOTES

The following description is a summary of the terms of the Notes being offered by this prospectus supplement. The description is qualified in its entirety by reference to the senior notes indenture, dated as of March 28, 2013, between us and U.S. Bank Trust Company, National Association (successor to U.S. Bank National Association), as trustee (the “base indenture”), as amended by the first supplemental indenture, to be dated as of the date of the initial issuance of the Notes, between us and U.S. Bank Trust Company, National Association, as trustee (the “first supplemental indenture” and, together with the base indenture, the “senior notes indenture”). You should read the senior notes indenture, the associated documents and the following description carefully to fully understand the terms of the Notes. The base indenture has been attached as an exhibit to the registration statement of which this prospectus supplement is a part. The first supplemental indenture will be attached as an exhibit to a Current Report on Form 8-K that we will file with the SEC in connection with this offering and will be incorporated by reference into the registration statement of which this prospectus supplement is a part. In addition, to the extent that the following description is inconsistent with that contained in the accompanying prospectus under “Description of Debt Securities We May Offer”, you should rely on this description.

General Terms of the Notes

Assurant, Inc. will issue $175.0 million aggregate principal amount of 6.100% Senior Notes due 2026 under the senior notes indenture. Interest on and principal of the Notes will be payable in U.S. dollars. The Notes will be issued only in denominations of $2,000 and integral multiples of $1,000 in excess thereof. There will be no sinking fund payments for the Notes.

U.S. Bank Trust Company, National Association will act as trustee, security registrar and transfer agent for the Notes until such time as a successor trustee, security registrar or transfer agent may be appointed. We maintain customary banking relationships with U.S. Bank Trust Company, National Association, U.S. Bank National Association and certain of their respective affiliates.

Additional Notes

We may, without the consent of the holders of the Notes, issue additional notes having the same ranking, interest rate, maturity date, redemption rights and other terms as the Notes offered by this prospectus supplement. Any such additional notes will be a part of the series having the same terms as the Notes, provided that if the additional notes are not fungible with the Notes offered hereby for U.S. federal income tax purposes, the additional notes will have a different CUSIP number.

Interest

The Notes will initially be limited to $175.0 million aggregate principal amount. The Notes will bear interest at 6.100% per year. Interest will be payable semi-annually in arrears on February 27 and August 27 of each year, beginning August 27, 2023. Interest on the Notes will accrue from February 28, 2023, or from the most recent date to which interest has been paid or provided for. Interest on the Notes will be paid to holders of record on the February 12 or August 12 immediately preceding the interest payment date. Interest on the Notes will be computed on the basis of a 360-day year consisting of twelve 30-day months.

If an interest payment date for the Notes falls on a day that is not a business day, the interest payment shall be postponed to the next succeeding business day, and no interest on such payment shall accrue for the period from and after such interest payment date. It will be an event of default under the senior notes indenture if we fail to pay interest when due and such failure continues for 30 days.

The Notes will mature on February 27, 2026. If the maturity date for the Notes falls on a day that is not a business day, the principal and interest shall be due on the next succeeding business day, and no interest on such payment shall accrue for the period from and after the maturity date.

S-11

Ranking

The Notes will be senior unsecured obligations of Assurant, Inc. and will rank equally with all of our other senior unsecured indebtedness from time to time outstanding. As of December 31, 2022, we had $1.5 billion of outstanding senior indebtedness. In addition, we had an additional $499.8 million of available borrowing under our revolving credit facility, all of which would be unsecured indebtedness. See “Capitalization” for more information.

Interest Rate Adjustment

The interest rate payable on the Notes will be subject to adjustment from time to time, in the manner set forth below, if any of Moody’s Investor Service, Inc. (“Moody’s”) or S&P Global Ratings, a division of S&P Global Inc. (“S&P”) (or, in either case, a substitute Rating Agency therefor) downgrades or subsequently upgrades the credit rating assigned to the Notes. If the rating on the Notes from either of Moody’s or S&P is a rating set forth in the table below (or, in either case, the equivalent thereof, in the case of a substitute Rating Agency), the interest rate payable on the Notes shall increase from the stated interest rate payable on the Notes on the date of their initial issuance by the sum of the number of basis points set forth next to each such rating.

For so long as only one Rating Agency provides a rating on the Notes, any subsequent increase or decrease in the interest rate on the Notes necessitated by a reduction or increase in the rating by the Rating Agency providing the rating shall be twice the applicable number of basis points set forth in the applicable table above. For so long as no Rating Agency provides a rating on the Notes, the interest rate on the Notes will increase to, or remain at, as the case may be, 2.000% above the stated interest rate payable on the Notes on the date of their initial issuance.

If any Rating Agency changes its rating or initiates a rating with respect to the Notes, the per annum interest rate on the Notes will be increased or decreased in accordance with the foregoing requirements.

Any interest rate increase or decrease described above will take effect from the first day of the first interest payment period following the interest payment period during which a rating change occurs that requires an adjustment in the interest rate. As such, interest will not accrue at such increased or decreased rate until the next interest payment period following the interest payment period during which a rating change occurs. If any Rating Agency changes its rating on the Notes more than once during any particular interest period, the last such change to occur will control for purposes of the rating provided by such Rating Agency for the applicable interest period.

The interest rate on the Notes will permanently cease to be subject to any adjustment described above (notwithstanding any subsequent decrease in the ratings by any Rating Agency) if the Notes becomes rated Baa1 and BBB+ (or, in either case, the equivalent thereof, in the case of a substitute Rating Agency) or higher by Moody’s and S&P (or, in either case, a substitute Rating Agency therefor), respectively, with a stable or positive outlook (or one of these ratings if the Notes are only rated by one Rating Agency).

In no event shall: (1) the per annum interest rate on the Notes be reduced below the stated interest rate payable on the Notes on the date of their initial issuance, and (2) the total increase in the per annum interest rate on the Notes exceed 200 basis points above the stated interest rate payable on the Notes on the date of their initial issuance. Nothing herein shall be construed as a requirement that the Company obtain a rating on the Notes from any Rating Agency or otherwise.

S-12

For the purposes of this section:

“Rating Agency” means each of Moody’s and S&P, or if Moody’s or S&P shall not make a rating on the Notes, as applicable, publicly available, a nationally recognized statistical rating organization or organizations, as the case may be, selected by the Company (as certified by a resolution of the Board of Directors) that shall be substituted for Moody’s or S&P, as the case may be.

Optional Redemption

Prior to January 27, 2026 (the date that is one month prior to their maturity date) (the “Par Call Date”), the Company may redeem the Notes at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 25 basis points less (b) interest accrued to, but excluding, the date of redemption, and

(2) 100% of the principal amount of the Notes to be redeemed,

plus, in either case, accrued and unpaid interest thereon to, but excluding, the redemption date.

On or after the Par Call Date, the Company may redeem the Notes at its option, in whole or in part, at any time or from time to time, at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to, but excluding, the redemption date.

“Treasury Rate” means, with respect to any redemption date, the yield determined by the Company in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) - H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities—Treasury constant maturities—Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields—one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life—and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity

S-13

date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

The Company’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

The redemption price will be quoted to the trustee in writing and the trustee shall have no duty to determine or verify the calculation of the redemption price.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 but not more than 60 days before the redemption date to each holder of record of the Notes to be redeemed at its registered address. Any redemption or notice may, at the Company’s discretion, be subject to one or more conditions precedent and, at the Company’s discretion, the redemption date may be delayed until such time as any or all such conditions precedent included at the Company’s discretion shall be satisfied (or waived by the Company) or the redemption date may not occur and such notice may be rescinded if all such conditions precedent included at the Company’s discretion shall not have been satisfied (or waived by the Company). The notice of redemption for the Notes to be redeemed will state, among other things, the amount of the Notes to be redeemed, the redemption date, the manner of calculation of the redemption price and the place or places that payment will be made upon presentation and surrender of the Notes to be redeemed. If less than all of the Notes are to be redeemed at the Company’s option, the trustee will select, in a manner it deems fair and appropriate, in its discretion, the Notes, or portions of the Notes, to be redeemed. Unless the Company defaults in the payment of the redemption price, interest will cease to accrue on any Notes that have been called for redemption at the redemption date.

The Company will not be required (i) to issue, register the transfer of or exchange the Notes to be redeemed during a period beginning at the opening of business 15 days before the day of the mailing or electronic delivery (or other transmission in accordance with the depositary’s procedures) of a notice of redemption of the Notes selected for redemption and ending at the close of business on the day of such mailing or electronic delivery (or other transmission in accordance with the depositary’s procedures), or (ii) to register the transfer of or exchange the Notes so selected for redemption in whole or in part, except the unredeemed portion of such Notes being redeemed in part.

Applicable Law

The Notes will be, and the senior notes indenture is, governed by and construed in accordance with the laws of the State of New York.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

The following is a discussion of material U.S. federal income tax consequences of ownership and disposition of the Notes. This discussion applies only to Notes that are:

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

If an entity that is classified as a partnership for U.S. federal income tax purposes holds Notes, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and upon the activities of the partnership. Partnerships holding Notes and partners in such partnerships should consult their own tax advisors as to the particular U.S. federal income tax consequences of owning and disposing of the Notes.

This summary is based on the Code, administrative pronouncements, judicial decisions and final, temporary and proposed Treasury Regulations as of the date hereof, changes to any of which may affect the tax consequences described herein (possibly with retroactive effect).

This summary addresses only U.S. federal income tax consequences. Persons considering the purchase of Notes are urged to consult their tax advisors with regard to the application of the U.S. federal income or other federal tax laws (including estate and gift tax laws and the Medicare tax on investment income) to their particular situations as well as any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction.

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

S-15

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

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

Taxation of the Notes

Potential contingent payment debt treatment

Our obligation to pay additional interest on the Notes upon a change in our credit rating may implicate the provisions of the Treasury Regulations relating to “contingent payment debt instruments.” We intend to take the position that the Notes should not be treated as contingent payment debt instruments and this discussion generally assumes that the regulations relating to “contingent payment debt instruments” are not applicable. However, we can give you no assurance that our position would be sustained if challenged by the Internal Revenue Service (“IRS”). A successful challenge of this position by the IRS could affect the timing and amount of a holder’s income and could cause the gain from the sale or other disposition of a Note to be treated as ordinary income rather than capital gain. Our position regarding the applicability of the regulations relating to “contingent payment debt instruments” is binding on a holder unless the holder discloses in a proper manner to the IRS that it is taking a different position. Holders are urged to consult their tax advisors regarding the possible application of the contingent payment debt instrument rules to the Notes.

Tax Consequences to U.S. Holders of the Notes

Payments of stated interest

Stated interest paid on a Note will be taxable to a U.S. Holder as ordinary interest income at the time it accrues or is received in accordance with the U.S. Holder’s method of accounting for U.S. federal income tax purposes.

Sale, exchange or retirement of the Notes

Upon the sale, exchange or retirement of a Note, a U.S. Holder generally will recognize taxable gain or loss equal to the difference between the amount realized on the sale, exchange or retirement and the holder’s adjusted tax basis in the Note. For these purposes, the amount realized does not include any amount attributable to accrued but unpaid stated interest, which will be taxable as interest to the extent not previously included in income. A U.S. Holder’s adjusted tax basis in a Note generally will equal the cost of the Note to the holder.

Gain or loss realized on the sale, exchange or retirement of a Note generally will be capital gain or loss and will be long-term capital gain or loss if at the time of the sale, exchange or retirement the Note has been held for more than one year. For non-corporate taxpayers, long-term capital gains are generally eligible for reduced rates of taxation. The deductibility of capital losses may be subject to limitations.

S-16

Backup withholding and information reporting

Information returns may be filed with the IRS in connection with payments on the Notes and the proceeds from a sale or other disposition (including a retirement) of the Notes. A U.S. Holder may be subject to U.S. backup withholding on these payments if the U.S. Holder fails to provide its taxpayer identification number to the applicable withholding agent and comply with certain certification procedures or otherwise establish an exemption from backup withholding. Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a credit against the U.S. Holder’s U.S. federal income tax liability and may entitle the U.S. Holder to a refund, provided that the required information is timely furnished to the IRS. U.S. Holders should consult their tax advisors concerning the application of information reporting and backup withholding rules.

Tax Consequences to Non-U.S. Holders of the Notes

General

Subject to the discussion below concerning “FATCA,” backup withholding and effectively connected income:

If a Non-U.S. Holder of a Note is engaged in a trade or business in the United States, and if interest and/or gain on the Note is effectively connected with the conduct of this trade or business, the Non-U.S. Holder, although exempt from the withholding tax on interest discussed in the preceding paragraph, will generally be taxed in the same manner as a U.S. Holder (see “Tax Consequences to U.S. Holders of the Notes” above), except that the Non-U.S. Holder will be required to provide a properly executed IRS Form W-8ECI in order to claim an exemption from the withholding tax on interest discussed in the preceding paragraph. In addition, a Non-U.S. Holder that is a corporation generally will be subject to a branch profits tax at a rate of 30% on its effectively-connected earnings and profits (subject to certain adjustments). Non-U.S. Holders are urged to consult their tax advisors regarding whether an applicable income tax treaty provides for a different result and regarding other U.S. federal income tax consequences of the ownership and disposition of Notes.

Backup withholding and information reporting

Information returns are required to be filed with the IRS in connection with payments of interest on the Notes. The IRS may make this information available under the provisions of an applicable income tax treaty to the tax authorities in the country in which the Non-U.S. Holder is resident. Unless the Non-U.S. Holder complies with certification procedures to establish that it is not a U.S. person, information returns may be filed with the IRS in connection with the proceeds from a disposition (including a retirement) of the Notes and the Non-U.S. Holder may be subject to backup withholding with respect to payments on the Notes or on the proceeds from a

S-17

disposition of the Notes. The certification procedures required to claim the exemption from withholding tax on interest described above will satisfy the certification requirements necessary to avoid backup withholding as well. Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a Non-U.S. Holder will be allowed as a credit against the Non-U.S. Holder’s U.S. federal income tax liability and may entitle the Non-U.S. Holder to a refund, provided that the required information is timely furnished to the IRS. Non-U.S. Holders should consult their tax advisors concerning the application of information reporting and backup withholding rules.

FATCA Legislation

Provisions commonly referred to as “FATCA” impose withholding of 30% on payments of interest on the Notes and of proceeds of sales or redemptions of the Notes to “foreign financial institutions” (which is broadly defined for this purpose and in general includes investment vehicles) and certain other non-U.S. entities unless various U.S. information reporting and due diligence requirements (generally relating to ownership by U.S. persons of interests in or accounts with those entities) have been satisfied, or an exemption applies. Under proposed Treasury Regulations, this withholding tax will not apply to the proceeds of sales or redemptions of the Notes. The preamble to these proposed Treasury Regulations indicates that taxpayers may rely on them pending their finalization. If FATCA withholding is imposed, a beneficial owner that is not a foreign financial institution generally will be entitled to a refund of any amounts withheld by filing a U.S. federal income tax return (which may entail significant administrative burden). Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules. Prospective investors should consult their tax advisors regarding the effects of FATCA on their investment in the Notes.

CERTAIN BENEFIT PLAN CONSIDERATIONS

A fiduciary of a pension, profit-sharing or other employee benefit plan subject to Title I of the U.S. Employee Retirement Income Security Act of 1974, as amended (“ERISA”, and each such plan, an “ERISA Plan”), should consider the fiduciary standards of ERISA in the context of the ERISA Plan’s particular circumstances before authorizing an investment in the Notes. Among other factors, the fiduciary should consider whether the investment would satisfy the prudence and diversification requirements of ERISA and would be consistent with the documents and instruments governing the ERISA Plan, and whether the investment would involve a prohibited transaction under ERISA or the Code.

Section 406 of ERISA and Section 4975 of the Code prohibit (i) ERISA Plans, (ii) individual retirement accounts, Keogh plans and other plans or arrangements that are subject to Section 4975 of the Code (“Code Plans”) and (iii) entities whose underlying assets include “plan assets” by reason of any ERISA Plan’s or Code Plan’s investment in the entity (each of the foregoing described in clauses (i), (ii) and (iii) referred to as “Covered Plans”), from engaging in certain transactions involving “plan assets” with persons who are “parties in interest” under ERISA or “disqualified persons” under the Code with respect to the Covered Plan. A violation of these prohibited transaction rules may result in excise tax or other liabilities under ERISA or the Code for those persons, unless exemptive relief is available under an applicable statutory, regulatory or administrative exemption.

We, the underwriters and certain of our and their affiliates, among others, may each be considered a party in interest and a disqualified person with respect to many Covered Plans. The acquisition, holding and disposition of Notes by a Covered Plan with respect to which we, any of the underwriters or certain of our or their affiliates is or becomes a party in interest or disqualified person may result in a prohibited transaction under ERISA or Section 4975 of the Code, unless the Notes are acquired, held and disposed of pursuant to an applicable exemption, as applicable. The U.S. Department of Labor has issued five prohibited transaction class exemptions, or “PTCEs”, that may provide exemptive relief if required for direct or indirect prohibited transactions that may arise from the purchase, holding or disposition of Notes. These exemptions are PTCE 84-14 (for certain transactions determined by independent qualified professional asset managers), PTCE 90-1 (for certain transactions involving insurance company pooled separate accounts), PTCE 91-38 (for certain transactions involving bank collective investment funds), PTCE 95-60 (for transactions involving certain insurance company general accounts), and PTCE 96-23 (for transactions managed by in-house asset managers). In addition, ERISA Section 408(b)(17) and Section 4975(d)(20) of the Code may provide an exemption for the acquisition and disposition of Notes, provided that neither the issuer of the Notes offered hereby nor any of its affiliates have or exercise any discretionary authority or control or render any investment advice with respect to the assets of any Covered Plan involved in the transaction, and provided further that the Covered Plan pays no more and receives no less than “adequate consideration” in connection with the transaction (the “service provider exemption”). Each of the above-noted exemptions contains conditions and limitations on its application. Fiduciaries of a Covered Plan considering acquiring Notes in reliance on these or any other exemption should carefully review the exemption to assure it is applicable. There can be no assurance that all of the conditions of any such exemptions will be satisfied with respect to transactions involving the Notes.

Due to the complexity of these rules and the penalties that may be imposed upon persons involved in non-exempt prohibited transactions, it is important that fiduciaries or other persons considering purchasing Notes on behalf of or with the assets of any Covered Plan consult with their counsel regarding the availability of exemptive relief, as applicable.

While employee benefit plans that are governmental plans (as defined in Section 3(32) of ERISA), certain church plans (as defined in Section 3(33) of ERISA) and non-U.S. plans (as described in Section 4(b)(4) of ERISA) (“Other Plan Arrangements”) are not subject to the requirements of Title I of ERISA or Section 4975 of the Code, they may be subject to similar provisions under applicable federal, state, local, non-U.S. or other laws

S-19

or regulations (“Similar Laws”). Fiduciaries of Other Plan Arrangements should consult with their counsel regarding the potential consequences of an investment in the Notes under any applicable Similar Laws before acquiring the Notes.

Representation

Each purchaser or holder of Notes or any interest therein represents by its purchase, holding and disposition of Notes that either (1) it is not a Plan or Other Plan Arrangement and it is not purchasing or holding the Notes on behalf of or with the assets of any Plan or Other Plan Arrangement, or (2) its purchase, holding and disposition of the Notes will not constitute or result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or a violation under any applicable Similar Laws.

Purchasers of Notes have exclusive responsibility for ensuring that their purchase and holding of Notes do not violate the fiduciary responsibility or prohibited transaction rules of Title I of ERISA or Section 4975 of the Code or any provisions of applicable Similar Laws. The sale of any Notes to a Covered Plan or Other Plan Arrangement is in no respect a representation by us or any of our affiliates or representatives that such an investment meets all relevant legal requirements with respect to investments by any such Covered Plans or Other Plan Arrangements generally or any particular Covered Plan or Other Plan Arrangement or that such investment is appropriate for such Covered Plans or Other Plan Arrangements generally or any particular Covered Plan or Other Plan Arrangement. Neither this discussion nor anything provided in this prospectus supplement is or is intended to be investment advice directed at any potential benefit plan investor or at benefit plan investors generally and such purchasers should consult and rely on their own counsel and advisors as to whether an investment in the Notes is suitable.

UNDERWRITING

J.P. Morgan Securities LLC and Wells Fargo Securities, LLC are acting as joint book-running managers of the offering and as representatives of the underwriters named below.

Subject to the terms and conditions stated in the underwriting agreement dated the date of this prospectus supplement, each underwriter named below has severally agreed to purchase, and we have agreed to sell to that underwriter, the principal amount of Notes set forth opposite the underwriter’s name.

The underwriters have agreed to purchase all of the Notes sold pursuant to the underwriting agreement if any of these 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 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 officer’s 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.

Commissions and Discounts

The underwriters have advised us that they propose initially to offer the Notes to the public at the public offering price on the cover page of this prospectus supplement, and may offer the Notes to dealers at that price less a concession not in excess of 0.350% of the principal amount of the Notes. The underwriters may allow, and the dealers may reallow, a discount not in excess of 0.250% of the principal amount of the Notes to other dealers. After the initial public offering, the public offering price, concession and discount may be changed.

The following table shows the underwriting discount that we will pay to the underwriters in connection with the offering of the Notes:

S-21

The expenses of the offering, not including the underwriting discount, are estimated to be $0.8 million and are payable by us.

New Issue of Notes

The Notes are a new issue of securities with no established trading market. 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 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 the trading market for the Notes or that an active public trading market for the Notes will develop. If an active public trading market for the Notes does not develop, the market price and liquidity of the Notes may be adversely affected.

A prospectus supplement in electronic format may be made available on websites maintained by one or more underwriters, or selling group members, if any, participating in this offering. The representatives may agree to allocate a number of units to underwriters for sale to their online brokerage account holders. Internet distributions will be allocated by the representatives to underwriters that may make Internet distributions on the same basis as other allocations.

We expect to deliver the Notes against payment for the Notes on the third business day following the date of the pricing of the Notes, which we refer to as T+3. Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in two business days, unless the parties to a trade expressly agree otherwise. Accordingly, investors who wish to trade the Notes on any date prior to the second business day before delivery will be required, by virtue of the fact that the Notes initially will settle in T+3, to specify alternative settlement arrangements to prevent a failed settlement. Purchasers of the Notes who wish to trade the Notes prior to the second business day before the anticipated delivery hereunder should consult with their own advisors.

Price Stabilization and Short Positions

In connection with the offering, the underwriters are permitted to engage in transactions that stabilize the market price of the Notes. Such transactions consist of bids or purchases to peg, fix or maintain the price of the Notes. If the underwriters create a short position 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 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 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 price 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.

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. Certain of the underwriters and their respective affiliates have, from time to time, performed, and may in the future perform, various financial advisory and investment banking services for us, for which they received or will receive customary fees and expenses. In addition, certain of the underwriters or their affiliates are lenders under our revolving credit facility. Each of these parties have received or will receive customary fees in connection therewith.

S-22

U.S. Bancorp Investments, Inc., one of the underwriters, is an affiliate of U.S. Bank Trust Company, National Association, the trustee, security registrar and transfer agent under the senior notes indenture and the Notes. We maintain customary banking relationships with U.S. Bank Trust Company, National Association and U.S. Bank National Association.

We intend to use the net proceeds from this offering (and available cash on hand) to redeem a portion of the $225.0 million outstanding aggregate principal amount of our 2023 Notes and to pay related premiums, fees and expenses. Certain of the underwriters in this offering or their affiliates may own the 2023 Notes that are being redeemed with the proceeds from this offering and, as a result, may receive a portion of the proceeds from this offering. Accordingly, affiliates of certain of the underwriters may receive a portion of the proceeds of the offering.

Certain of the underwriters or their affiliates that have a lending relationship with us routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies, which may consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the Notes offered hereby. In addition, in the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers and may at any time hold long and short positions in such securities and instruments. Such investment and securities activities may involve our securities and instruments, including the Notes. Any such credit default swaps or short positions could adversely affect future trading prices of the Notes. The underwriters and their respective affiliates may also make investment recommendations or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long or short positions in such securities and instruments.

Notice to Prospective Investors in the 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 2016/97/EU (as amended, the “Insurance Distribution Directive”), 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 Regulation (EU) 2017/1129 (as amended, the “Prospectus Regulation”). Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the Notes 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.

In addition, our Global Lifestyle, Global Housing and Global Preneed segments generate significant operating cash flows, which provides us with the flexibility to make investments to strengthen our strategic capabilities and enter into and grow partnerships with our clients.

Client and consumer insights and evolving capabilities support innovation. During our long business tenure, we have developed a comprehensive understanding of our clients and the consumer markets we serve. We seek to leverage consumer insights, together with deep market knowledge and capabilities, to anticipate and identify the specific needs of our clients and the consumers they serve. We intend to continue capitalizing on our consumer insights, as well as to leverage investments in emerging technologies, to introduce new and innovative products and services and adapt those offerings to anticipate and address emerging issues.

Value chain integration. We own or manage multiple pieces of the value chain, which enables us to create products and service offerings based on client needs and provide a seamless experience for consumers. Offering end-to-end solutions allows us to provide additional value for consumers and adapt more quickly and efficiently to their needs. Visibility across the value chain helps us leverage insights to further improve the customer experience and our offerings.

Our Strategy for Profitable Growth

Our vision is to be the premier provider of lifestyle and housing solutions globally. To achieve this vision, we positioned ourselves for continued long-term profitable growth by:

Growing our portfolio of market leading businesses. We leverage our competitive strengths to focus on businesses where we can maintain or reach market-leading positions, achieve attractive returns and grow. We periodically assess our business portfolio to ensure we align resources with the best opportunities and we have

1

identified Connected Living, Global Automotive and Multifamily Housing as key businesses targeted for growth. We intend to grow our businesses by continuing to invest in capabilities and technology which allows us to innovate and deliver superior customer experience, as well as further expanding our offerings and diversifying our distribution channels.

Providing integrated offerings. We provide an array of services that are complementary to our risk-based products. As we adapt our business portfolio and capabilities to respond to client and consumer needs, we expect to continue to drive additional value to consumers by expanding our fee-for-service offerings and evolving our mix of business. We expect to generate a more diversified mix of business and earnings.

Deploying our capital strategically. We deploy capital to invest in and grow our businesses, repurchase shares and pay dividends. Our approach to mergers, acquisitions and other growth opportunities reflects our strategic and disciplined approach to capital management. We target new businesses and capabilities that complement or support our strategy, which is focused on expanding capabilities and distribution in targeted growth businesses globally.

DESCRIPTION OF DEBT SECURITIES WE MAY OFFER

References to “Assurant,” the “Company,” “us,” “we” or “our” in this section mean Assurant, Inc., and do not include the subsidiaries of Assurant, Inc. Also, in this section, references to “holders” mean those who own debt securities registered in their own names, on the books that we or the applicable trustee maintain for this purpose, and not those who own beneficial interests in debt securities registered in street name or in debt securities issued in book-entry form through one or more depositaries. When we refer to “you” in this prospectus, we mean all purchasers of the securities being offered by this prospectus, whether they are the holders or only indirect owners of those securities. Owners of beneficial interests in the debt securities should read the section below entitled “Legal Ownership and Book-Entry Issuance”.

Debt Securities May Be Senior or Subordinated

We may issue senior or subordinated debt securities. Neither the senior debt securities nor the subordinated debt securities will be secured by any of our property or assets or the property or assets of our subsidiaries. Thus, by owning a debt security, you are one of our unsecured creditors.

The senior debt securities and, in the case of senior debt securities in bearer form, any related interest coupons, will be issued under our senior debt indentures described below and will rank equally with all of our other unsecured and unsubordinated debt.

The subordinated debt securities and, in the case of subordinated debt securities in bearer form, any related interest coupons, will be issued under our subordinated debt indenture described below and will be subordinate in right of payment to all of our “senior indebtedness,” as defined in the subordinated debt indenture. Neither indenture limits our ability to incur additional unsecured indebtedness.

When we refer to “debt securities” in this prospectus, we mean both the senior debt securities and the subordinated debt securities issued under the indentures (as defined below).

The Senior and Subordinated Debt Indentures

The senior debt securities are governed by documents called the “senior debt indentures” (the Senior Debt Indenture dated as of February 18, 2004 between us and U.S. Bank National Association, as successor to SunTrust Bank, as trustee, which we refer to as the “2004 senior debt indenture”, and the Indenture, dated as of March 28, 2013, between us and U.S. Bank National Association, as trustee, which we refer to as the “2013 senior debt indenture”), and the subordinated debt securities are governed by the Subordinated Indenture dated as of March 27, 2018 between us and U.S. Bank National Association, as trustee, which we refer to as the “subordinated debt indenture” (and together with the senior debt indentures, the “indentures”). A number of provisions of our three indentures are identical; however, the provisions relating to subordination are included only in the subordinated debt indenture and certain provisions described below under “—Notices”, “—Modification and Waiver of the Debt Securities”, “—Reports”, “—Restrictive Covenants” and “—Events of Default” vary substantially among the indentures.

Reference to the indenture or the trustee with respect to any debt securities, means the indenture under which those debt securities are issued and the trustee under that indenture. See “–– Our Relationship with the Trustee”.

The trustee has two main roles:

1. The trustee can enforce the rights of holders against us if we default on our obligations under the terms of the indentures or the debt securities. There are some limitations on the extent to which the trustee acts on behalf of holders, described below under “— Events of Default — Remedies If an Event of Default Occurs”.

8

2. The trustee performs administrative duties for us, such as sending interest payments and notices to holders, and transferring a holder’s debt securities to a new buyer if a holder sells.

The indentures and their associated documents contain the full legal text of the matters described in this section. The indentures and the debt securities are governed by New York law. A copy of each indenture is an exhibit to our registration statement. See “Where You Can Find More Information” for information on how to obtain a copy.

We may issue as many distinct series of debt securities under any of the indentures as we wish. The provisions of the senior debt indentures and the subordinated debt indenture allow us not only to issue debt securities with terms different from those previously issued under the applicable indenture, but also to “reopen” a previous issue of a series of debt securities and issue additional debt securities of that series. We may issue debt securities in amounts that exceed the total amount specified on the cover of your prospectus supplement at any time without your consent and without notifying you. In addition, we may offer debt securities, together with other debt securities, warrants, stock purchase contracts, preferred stock or common stock in the form of units, as described below under “Description of Units We May Offer”.

This section summarizes the material terms of the debt securities that are common to all series, although the prospectus supplement which describes the terms of each series of debt securities may also describe differences from the material terms summarized here.

Because this section is a summary, it does not describe every aspect of the debt securities. This summary is subject to and qualified in its entirety by reference to all the provisions of the indenture, including definitions of certain terms used in the indenture. In this summary, we describe the meaning of only some of the more important terms. For your convenience, we also include references in parentheses to certain sections of the indenture. Whenever we refer to particular sections or defined terms of the indenture in this prospectus or in the prospectus supplement, such sections or defined terms are incorporated by reference here or in the prospectus supplement. You must look to the indenture for the most complete description of what we describe in summary form in this prospectus.

This summary also is subject to and qualified by reference to the description in the prospectus supplement of the particular terms of the series of debt securities you are offered. Those terms may vary from the terms described in this prospectus. The prospectus supplement relating to each series of debt securities will be attached to the front of this prospectus. There may also be a further prospectus supplement, known as a pricing supplement, which contains the precise terms of debt securities you are offered.

Under the 2013 senior debt indenture and the subordinated debt indenture (but not the 2004 senior debt indenture), we may issue the debt securities as original issue discount securities, which will be offered and sold at a substantial discount below their stated principal amount. (Section 101 of the 2013 senior debt indenture and the subordinated debt indenture) The prospectus supplement relating to original issue discount securities will describe federal income tax consequences and other special considerations applicable to them. The debt securities may also be issued as indexed securities or securities denominated in foreign currencies or currency units, as described in more detail in the prospectus supplement relating to any of the particular debt securities. The prospectus supplement relating to specific debt securities will also describe the risks and certain additional tax considerations applicable to such debt securities.

In addition, the specific financial, legal and other terms particular to a series of debt securities will be described in the prospectus supplement and, if applicable, a pricing supplement relating to the series. The prospectus supplement relating to a series of debt securities will describe the following terms of the series:

9

10

In addition to the items above, the prospectus supplement relating to a series of debt securities issued under the 2004 senior debt indenture will also describe the following terms of the series:

An investment in debt securities may involve special risks, including risks associated with indexed securities and currency-related risks if the debt security is linked to an index or is payable in or otherwise linked to a non-U.S. dollar currency. We will describe these risks in the prospectus supplement relating to specific debt securities.

Overview of Remainder of this Description

The remainder of this description summarizes:

Additional Mechanics

Form, Exchange and Transfer

Unless we specify otherwise in the prospectus supplement, the debt securities will be issued:

If a debt security is issued as a registered global debt security, only the depositary — e.g., DTC, Euroclear and Clearstream, each as defined below under “Legal Ownership and Book-Entry Issuance” — will be entitled to transfer and exchange the debt security as described in this subsection, since the depositary will be the sole holder of the debt security. Those who own beneficial interests in a global security do so through participants in the depositary’s securities clearance system, and the rights of these indirect owners will be governed solely by the applicable procedures of the depositary and its participants. We describe book-entry procedures below under “Legal Ownership and Book-Entry Issuance”.

11

Holders may have their debt securities broken into more debt securities of smaller denominations of not less than $1,000 or combined into fewer debt securities of larger denominations, as long as the total principal amount is not changed. (Section 305 of the 2013 senior debt indenture and the subordinated debt indenture, Section 3.5 of the 2004 senior debt indenture) This is called an exchange.

Holders may exchange or transfer debt securities at the office of the trustee. They may also replace lost, stolen or mutilated debt securities at that office. The trustee acts as our agent for registering debt securities in the names of holders and transferring debt securities. We may change this appointment to another entity or perform this service ourselves. The entity performing the role of maintaining the list of registered holders is called the security registrar. It will also perform transfers. (Section 305 of the 2013 senior debt indenture and the subordinated debt indenture, Section 3.5 of the 2004 senior debt indenture) The trustee’s agent may require an indemnity against any loss, liability or expense incurred without negligence or bad faith on its part arising out of or in connection with the acceptance or administration of the trust or trusts before replacing any debt securities.

Holders will not be required to pay a service charge to transfer or exchange debt securities, but holders may be required to pay for any tax or other governmental charge associated with the exchange or transfer. The transfer or exchange will only be made if the security registrar is satisfied with your proof of ownership.

If we designate additional transfer agents, they will be named in the prospectus supplement. We may cancel the designation of any particular transfer agent. We may also approve a change in the office through which any transfer agent acts. (Section 1002 of the 2013 senior debt indenture and the subordinated debt indenture, Section 10.2 of the 2004 senior debt indenture)

If the debt securities are redeemable and we redeem less than all of the debt securities of a particular series, we may block the transfer or exchange of debt securities during the period beginning 15 days before the day we mail the notice of redemption and ending on the day of that mailing, in order to freeze the list of holders to prepare the mailing. We may also refuse to register transfers or exchanges of debt securities selected for redemption, except that we will continue to permit transfers and exchanges of the unredeemed portion of any debt security being partially redeemed. (Section 305 of the 2013 senior debt indenture and the subordinated debt indenture, Section 3.5 of the 2004 senior debt indenture)

The rules for exchange described above apply to exchange of debt securities for other debt securities of the same series and kind. If a debt security is convertible, exercisable or exchangeable into or for a different kind of security, such as one that we have not issued, or for other property, the rules governing that type of conversion, exercise or exchange will be described in the prospectus supplement.

Payment and Paying Agents

We will pay interest to the person listed in the trustee’s records at the close of business on a particular day in advance of each due date for interest, even if that person no longer owns the debt security on the interest due date. That particular day, usually about two weeks in advance of the interest due date, is called the regular record date and will be stated in the prospectus supplement. (Section 307 of the 2013 senior debt indenture and the subordinated debt indenture, Section 3.10 of the 2004 senior debt indenture) Holders buying and selling debt securities must work out between them how to compensate for the fact that we will pay all the interest for an interest period to the one who is the registered holder on the regular record date. The most common manner is to adjust the sale price of the securities to pro-rate interest fairly between buyer and seller. This prorated interest amount is called accrued interest.

We will pay interest, principal and any other money due on the debt securities at the corporate trust office of the trustee in the Borough of Manhattan, the City of New York. That office is currently located at U.S. Bank National Association, ATTN: Global Corporate Trust Services, 100 Wall Street, 6th Floor, New York, New York 10005. Holders must make arrangements to have their payments picked up at or wired from that office. We may also choose to pay interest by mailing checks. For debt securities held in book-entry form, payment on the securities will be governed by the depositary’s rules and procedures as described generally under “Legal Ownership and Book-Entry Issuance”.

12

BOOK-ENTRY AND OTHER INDIRECT HOLDERS SHOULD CONSULT THEIR BANKS, BROKERS OR OTHER FINANCIAL INSTITUTIONS FOR INFORMATION ON HOW THEY WILL RECEIVE PAYMENTS.

We may also arrange for additional payment offices and may cancel or change these offices, including our use of the trustee’s corporate trust office. These offices are called paying agents. We may also choose to act as our own paying agent or choose one of our subsidiaries to do so. We must notify holders of changes in the paying agents for any particular series of debt securities. (Section 1002 of the 2013 senior debt indenture and the subordinated debt indenture, Section 10.2 of the 2004 senior debt indenture)

Notices

We and the trustee will send notices regarding the debt securities only to holders, using their addresses as listed in the trustee’s records. (Sections 101 and 106 of the 2013 senior debt indenture and the subordinated debt indenture, Sections 1.1 and 1.6 of the 2004 senior debt indenture) With respect to who is a legal “holder” for this purpose, see “Legal Ownership and Book-Entry Issuance”.

Regardless of who acts as paying agent, all money paid by us to a paying agent that remains unclaimed at the end of two years after the amount is due to holders, in the case of the 2013 senior debt indenture and the subordinated debt indenture, or at the end of three years after the amount is due to holders in the case of the 2004 senior debt indenture, will be repaid to us. After that two- or three-year period, holders may look only to us for payment and not to the trustee or any other paying agent. (Section 1003 of the 2013 senior debt indenture and the subordinated debt indenture, Section 10.5 of the 2004 senior debt indenture)

Special Situations

Mergers and Similar Transactions

We are generally permitted to consolidate or merge with another company or firm. We are also permitted to sell or lease substantially all of our assets to another company or firm, or to buy or lease substantially all of the assets of another company or firm. However, we may not take any of these actions unless the following conditions, among others, are met:

If we merge with or into another company or firm or sell or lease substantially all our assets to another company or firm, the other company or firm must be a corporation, partnership or trust organized under the laws of a State of the United States or the District of Columbia or under federal law, and it must agree to be legally responsible for the debt securities.

The merger, sale of assets or other transaction must not cause a default on the debt securities, and we must not already be in default, unless the merger or other transaction would cure the default. For purposes of this no-default test, a default would include an event of default that has occurred and not been cured. A default for this purpose would also include any event that would be an event of default if the requirements for giving us notice of our default or our default having to exist for a specific period of time were disregarded.

It is possible that the merger, sale of assets or other transaction would cause some of our property to become subject to certain liens or other preferential rights in that property over other lenders, including the holders of the senior debt securities. We have promised in our senior debt indentures to limit these preferential rights on voting stock of any Restricted Subsidiary (as defined in the 2013 senior debt indenture) or Principal Subsidiary (as defined in the 2004 senior debt indenture) as discussed under “— Restrictive Covenants — Limitation on Liens on Stock of Restricted and Principal Subsidiaries and on Issuance or Disposition of Stock of Restricted and Principal Subsidiaries”. If a merger or other transaction would create any liens on the voting stock of our Restricted Subsidiaries (as defined in the 2013 senior debt indenture) or Principal Subsidiaries (as defined in the 2004 senior debt indenture), as applicable, we must comply with that restrictive covenant. Either the liens will be permitted under the covenant, or we would be required to grant an equivalent or higher-ranking lien on the same voting stock to the holders of the senior debt securities.

13

Modification and Waiver of the Debt Securities

There are four types of changes we can make to the indenture and the debt securities issued under that indenture.

Changes Requiring Approval of All Holders. First, there are changes that cannot be made to the indenture or the debt securities without specific approval of each holder of a debt security affected in any material respect by the change under a particular debt indenture. Affected debt securities may be all or less than all of the debt securities issued under that debt indenture or all or less than all of the debt securities of a series.

Following is a list of those types of changes under the 2004 senior debt indenture:

Following is a list of those types of changes under the 2013 senior debt indenture and the subordinated debt indenture:

14

Changes Requiring a Majority Vote. The second type of change to the indenture and the debt securities is the kind that requires a vote in favor by holders of debt securities owning not less than a majority of the principal amount of the particular series affected or, if so provided and to the extent permitted by the Trust Indenture Act, of particular debt securities affected thereby. Most changes fall into this category, except for clarifying changes and certain other changes that would not adversely affect in any material respect holders of the debt securities. (Section 902 of the 2013 senior debt indenture and the subordinated debt indenture, Section 9.2 of the 2004 senior debt indenture) We may also obtain a waiver of a past default from the holders of debt securities owning a majority of the principal amount of the particular series affected. However, we cannot obtain a waiver of a payment default or any other aspect of the indenture or the debt securities listed in the first category described above under “— Changes Requiring Approval of All Holders” unless we obtain the individual consent of each holder to the waiver. (Section 513 of the 2013 senior debt indenture and the subordinated debt indenture, Section 5.13 of the 2004 senior debt indenture)

Changes Not Requiring Approval. The third type of change to the indenture and the debt securities does not require any vote by holders of debt securities. This type is limited to clarifications and certain other changes that would not adversely affect in any material respect holders of the debt securities. (Section 901 of the 2013 senior debt indenture and the subordinated debt indenture, Section 9.1 of the 2004 senior debt indenture)

We may also make changes or obtain waivers that do not adversely affect in any material respect a particular debt security, even if they affect other debt securities. In those cases, we do not need to obtain the approval of the holder of that debt security; we need only obtain any required approvals from the holders of the affected debt securities.

Modification of Subordination Provisions. We may not modify the subordination provisions of the subordinated debt indenture in a manner that would adversely affect in any material respect the outstanding subordinated debt securities without the consent of the holders of a majority of the principal amount of the particular series affected or, if so provided and to the extent permitted by the Trust Indenture Act, of particular subordinated debt securities affected thereby. Also, we may not modify the subordination provisions of any outstanding subordinated debt securities without the consent of each holder of our senior indebtedness that would be adversely affected thereby. The term “senior indebtedness” is defined below under “—Subordination Provisions”.

Further Details Concerning Voting. When taking a vote, we will use the following rules to decide how much principal amount to attribute to a debt security:

For original issue discount securities, we will use the principal amount that would be due and payable on the voting date if the maturity of the debt securities were accelerated to that date because of a default.

For debt securities whose principal amount is not known (for example, because it is based on an index), we will use a special rule for that debt security described in the prospectus supplement.

For debt securities denominated in one or more foreign currencies or currency units, we will use the U.S. dollar equivalent.

Debt securities will not be considered outstanding, and therefore not eligible to vote, if we have given a notice of redemption and deposited or set aside in trust for the holders money for the payment or redemption of the debt securities. Debt securities will also not be eligible to vote if they have been fully defeased as described below under “— Defeasance — Full Defeasance”. (Section 1302 of the 2013 senior debt indenture and the subordinated debt indenture, Section 4.2 of the 2004 senior debt indenture)

15

Under the 2013 senior debt indenture and the subordinated debt indenture, we will generally be entitled to set any day as a record date for the purpose of determining the holders of outstanding debt securities that are entitled to vote or take other action under the indenture. In certain limited circumstances, the trustee will be entitled to set a record date for action by holders. If we or the trustee set a record date for a vote or other action to be taken by holders of a particular series, that vote or action may be taken only by persons who are holders of outstanding securities of that series on the record date. We or the trustee, as applicable, may shorten or lengthen this period from time to time. (Section 104 of the 2013 senior debt indenture and the subordinated debt indenture)

Under the 2004 senior debt indenture, the Company may set a day as a record date for the purpose of determining the holders of outstanding debt securities that are entitled to vote or take other action under the indenture that is not more than 90 days prior to the date of such vote or other action. (Section 3.10 of the 2004 senior debt indenture)

BOOK-ENTRY AND OTHER INDIRECT HOLDERS SHOULD CONSULT THEIR BANKS, BROKERS OR OTHER FINANCIAL INSTITUTIONS FOR INFORMATION ON HOW APPROVAL MAY BE GRANTED OR DENIED IF WE SEEK TO CHANGE THE INDENTURE OR THE DEBT SECURITIES OR REQUEST A WAIVER.

Reports

The 2004 senior debt indenture provides that any documents or reports that we may be required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act will be filed with the trustee within 30 days after we have filed those documents or reports with the SEC.

The 2013 senior debt indenture and the subordinated debt indenture provide that any documents or reports that we may be required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act will be filed with the trustee within 15 days after we have filed those documents or reports with the SEC (the “Filing Obligation”). Under the Trust Indenture Act, we may have a separate obligation to file with the trustee documents or reports that we are required to file with the SEC. Under the 2013 senior debt indenture and the subordinated debt indenture (but not under the 2004 senior debt indenture), our failure to comply with the requirements of Section 314(a) of the Trust Indenture Act or our Filing Obligation or to file a report with the SEC as contemplated in the indenture or otherwise will not constitute an event of default under the 2013 senior debt indenture or the subordinated debt indenture. Accordingly, acceleration of our obligations under the debt securities will not be a remedy for our failure to file those documents or reports with the trustee, and you may have no remedy for the failure other than an action for damages.

Restrictive Covenants

General

We have made certain promises in each indenture called covenants where, among other things, we promise to maintain our corporate existence and all licenses and material permits necessary for our business. In addition, in the senior debt indentures, but not in the subordinated debt indenture, we have made the promises described below.

Limitation on Liens on Stock of Restricted and Principal Subsidiaries and on Issuance or Disposition of Stock of Restricted and Principal Subsidiaries

The 2013 senior debt indenture provides that we will not, nor will we permit any Restricted Subsidiary to, directly or indirectly, issue, assume, incur or guarantee any indebtedness for borrowed money (which we refer to in this prospectus as “Debt”) secured by a mortgage, security interest, pledge, lien or other encumbrance upon any shares of stock of any Restricted Subsidiary without effectively providing that the senior debt securities

16

(together with, if we shall so determine, any other indebtedness of or guarantee by us ranking equally with the senior debt securities and then existing or thereafter created) will be secured equally and ratably with that Debt. (Section 1006 of the 2013 senior debt indenture)

For purposes of the 2013 senior debt indenture, “Restricted Subsidiary” means each of Interfinancial Inc., Union Security Insurance Company and American Security Insurance Company so long as each remains a subsidiary, as well as any successor to all or a principal part of the business of that subsidiary and any other subsidiary which our board of directors designates as a Restricted Subsidiary. (Section 101 of the 2013 senior debt indenture)

The 2004 senior debt indenture provides that we will not, nor will we permit any of our Principal Subsidiaries to, directly or indirectly, create, issue, assume, incur, guarantee or permit to exist any Indebtedness that is secured by a mortgage, pledge, lien, security interest or other encumbrance on any of the common stock of a Principal Subsidiary owned by us or by any of our Principal Subsidiaries, unless our obligations under the debt securities and, if we so elect, any other of our Indebtedness ranking on a parity with, or prior to, the debt securities, shall be secured equally and ratably with, or prior to, such secured Indebtedness so long as it is outstanding and is so secured. (Section 10.3 of the 2004 senior debt indenture)

For the purposes of the 2004 senior debt indenture, “Indebtedness” is defined as the principal of and interest due on indebtedness of a Person, whether outstanding on the original date of issuance of the debt securities or thereafter created, incurred or assumed, which is (a) indebtedness for money borrowed and (b) any amendments, renewals, extensions, modifications and refundings of any such indebtedness. For the purposes of this definition, (i) “Person” means any individual, corporation, partnership, joint venture, association, joint stock company, trust, unincorporated organization or government or any agency or political subdivision thereof and (ii) “indebtedness for money borrowed” means (1) any obligation of, or any obligation guaranteed by, such Person for the repayment of borrowed money, whether or not evidenced by bonds, debentures, notes or other written instruments, (2) any obligation of, or any such obligation guaranteed by, such Person evidenced by bonds, debentures, notes or similar written instruments, including obligations assumed or incurred in connection with the acquisition of property, assets or businesses (provided, however, that (x) the deferred purchase price of any business or property or assets shall not be considered Indebtedness if the purchase price thereof is payable in full within 90 days from the date on which such indebtedness was created and (y) trade accounts payable and accrued liabilities arising in the ordinary course of business shall not be considered Indebtedness) and (3) any obligations of such Person as lessee under leases required to be capitalized on the balance sheet of the lessee under generally accepted accounting principles and leases of property or assets made as part of any sale and lease-back transaction to which such Person is a party. (Section 1.1 of the 2004 senior debt indenture)

Furthermore, for the purposes of the 2004 senior debt indenture, “Principal Subsidiary” means a consolidated subsidiary of Assurant that, as of the time of the determination of whether such consolidated subsidiary is a “Principal Subsidiary,” accounted, in each case, for 10% or more of the total assets of Assurant and its consolidated subsidiaries, as set forth in the most recent balance sheet filed by Assurant with the SEC. (Section 1.1 of the 2004 senior debt indenture)

We will not, nor will we permit any Restricted Subsidiary (under the 2013 senior debt indenture) or Principal Subsidiary (under the 2004 senior debt indenture) to, issue, sell, assign, transfer or otherwise dispose of, directly or indirectly, any capital stock, other than nonvoting preferred stock, of any Restricted Subsidiary or Principal Subsidiary, as applicable, except for:

17

For the purposes of the senior debt indentures, “capital stock” means any and all shares, interests, rights to purchase, warrants, options, participations or other equivalents of or interests in corporate stock. (Section 101 of the 2013 senior debt indenture and the subordinated debt indenture, Section 1.1 of the 2004 senior debt indenture)

Subordination Provisions

Holders of subordinated debt securities should recognize that contractual provisions in the subordinated debt indenture may prohibit us from making payments on those securities. Subordinated debt securities are subordinate and junior in right of payment, to the extent and in the manner stated in the subordinated debt indenture, to all of our senior indebtedness, as defined in the subordinated debt indenture, including all debt securities we have issued and will issue under the senior debt indentures.

The subordinated debt indenture defines “senior indebtedness” as all indebtedness and obligations of, or guaranteed or assumed by, us for borrowed money or evidenced by bonds, debentures, notes or other similar instruments, whether existing now or in the future and all amendments, renewals, extensions, modifications and refundings of any indebtedness or obligations of that kind. Senior debt excludes the subordinated debt securities and any other indebtedness or obligations that would otherwise constitute indebtedness if it is specifically designated as being subordinate in right of payment or equal in rank and right of payment to the subordinated debt securities.

The subordinated debt indenture provides that, unless all principal of and any premium or interest on the senior indebtedness has been paid in full, no payment or other distribution may be made in respect of any subordinated debt securities in the following circumstances:

If the trustee under the subordinated debt indenture or any holders of the subordinated debt securities receive any payment or distribution that is prohibited under the subordination provisions, then the trustee or the holders will have to repay that money to the holders of the senior indebtedness.

18

Even if the subordination provisions prevent us from making any payment when due on the subordinated debt securities of any series, we will be in default on our obligations under that series if we do not make the payment when due. This means that the trustee under the subordinated debt indenture and the holders of that series can take action against us, but they will not receive any money until the claims of the holders of senior indebtedness have been fully satisfied.

The subordinated debt indenture allows the holders of senior indebtedness to obtain a court order requiring us and any holder of subordinated debt securities to comply with the subordination provisions.

Defeasance

The following discussion of full defeasance and covenant defeasance will be applicable to each series of debt securities that is denominated in U.S. dollars and has a fixed rate of interest and will apply to other series of debt securities if we so specify in the prospectus supplement. (Section 1301 of the 2013 senior debt indenture and the subordinated debt indenture, Section 4.1 of the 2004 senior debt indenture)

Full Defeasance

If there is a change in U.S. federal tax law, as described below, we can legally release ourselves from any payment or other obligations on the debt securities, called full defeasance, if we put in place the following other arrangements for holders to be repaid:

19

If we ever did accomplish full defeasance, as described above, a holder would have to rely solely on the trust deposit for repayment on the debt securities. In addition, in the case of subordinated debt securities, the provisions described above under “— Subordination Provisions” would not apply. A holder could not look to us for repayment in the unlikely event of any shortfall.

Covenant Defeasance

Under current U.S. federal tax law, we can make the same type of deposit as described above and we will be released from the restrictive covenants under the debt securities that are described above under “— Restrictive Covenants” and that may be described in the prospectus supplement. This is called covenant defeasance. In that event, the holder would lose the protection of these covenants but would gain the protection of having money and U.S. government or U.S. government agency notes or bonds set aside in trust to repay the debt securities. In order to achieve covenant defeasance, we must do the following:

If we accomplish covenant defeasance, certain provisions of the indenture and the debt securities would no longer apply:

In addition, in the case of subordinated securities, the provisions described above under “— Subordination Provisions” will not apply if we accomplish covenant defeasance.

If we accomplish covenant defeasance, a holder can still look to us for repayment of the debt securities if there were a shortfall in the trust deposit. In fact, if one of the remaining events of default occurred (such as a bankruptcy) and the debt securities become immediately due and payable, there may be such a shortfall. (Sections 1303 and 1304 of the 2013 senior debt indenture and the subordinated debt indenture, Sections 4.3 and 4.4 of the 2004 senior debt indenture)

Events of Default

A holder will have special rights if an event of default occurs and is not cured, as described later in this subsection.

What Is An Event of Default? The term “Event of Default” means any of the following:

20

Remedies If an Event of Default Occurs. If you are the holder of a subordinated debt security, all remedies available upon the occurrence of an event of default under the subordinated debt indenture will be subject to the restrictions on the subordinated debt securities described above under “— Subordination Provisions”. If an event of default occurs, the trustee will have special duties. In that situation, the trustee will be obligated to use those of its rights and powers under the indenture, and to use the same degree of care and skill in doing so, that a prudent person would use in that situation in conducting his or her own affairs. If an event of default has occurred and has not been cured, the trustee or the holders of at least 25% in principal amount of the debt securities of the affected series may declare the entire principal amount (or, in the case of original issue discount securities, the portion of the principal amount that is specified in the terms of the affected debt security) of all the debt securities of that series to be due and immediately payable. This is called a declaration of acceleration of maturity. However, a declaration of acceleration of maturity may be cancelled, but only before a judgment or decree based on the acceleration has been obtained, by the holders of at least a majority in principal amount of the debt securities of the affected series. (Section 502 of the 2013 senior debt indenture and the subordinated debt indenture, Section 5.2 of the 2004 senior debt indenture) If we file for bankruptcy or certain other events of bankruptcy, insolvency or reorganization occur, then the principal amount of all the securities of that series (or, if any securities of that series are original issue discount securities, such portion of the principal amount of such securities as may be specified by the terms thereof) shall automatically, and without any declaration or other action on the part of the trustee or any holder, become immediately due and payable.

You should read carefully the prospectus supplement relating to any series of debt securities which are original issue discount securities for the particular provisions relating to acceleration of the maturity of a portion of the principal amount of original issue discount securities upon the occurrence of an event of default and its continuation.

21

Except in cases of default, where the trustee has the special duties described above, the trustee is not required to take any action under the indenture at the request of any holders unless the holders offer the trustee reasonable protection from expenses and liability called an indemnity. (Section 603 of the 2013 senior debt indenture and the subordinated debt indenture, Section 6.3 of the 2004 senior debt indenture) If indemnity reasonably satisfactory to the trustee is provided, the holders of a majority in principal amount of the outstanding securities of the relevant series may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. These majority holders may also direct the trustee in performing any other action under the applicable indenture with respect to the debt securities of that series, provided that:

Before you bypass the trustee and bring your own lawsuit or other formal legal action or take other steps to enforce your rights or protect your interests relating to the debt securities, the following must occur:

However, you are entitled at any time to bring a lawsuit for the payment of money due on your debt security on or after its due date. (Section 508 of the 2013 senior debt indenture and the subordinated debt indenture, Section 5.8 of the 2004 senior debt indenture)

BOOK-ENTRY AND OTHER INDIRECT HOLDERS SHOULD CONSULT THEIR BANKS, BROKERS OR OTHER FINANCIAL INSTITUTIONS FOR INFORMATION ON HOW TO GIVE NOTICE OR DIRECTION TO OR MAKE A REQUEST OF THE TRUSTEE AND TO MAKE OR CANCEL A DECLARATION OF ACCELERATION.

We will give to the trustee every year a written statement of certain of our officers certifying that to their knowledge we are in compliance with the applicable indenture and the debt securities issued under it, or else specifying any default. (Section 1004 of the 2013 senior debt indenture and the subordinated debt indenture, Section 10.6 of the 2004 senior debt indenture)

Governing Law

The indentures are, and the debt securities will be, governed by and construed in accordance with the laws of the State of New York.

22

Our Relationship with the Trustee

An affiliate of U.S. Bank National Association acts as one of our lenders and, from time to time, may provide other banking customary services to the Company and our subsidiaries.

U.S. Bank National Association is initially serving as the trustee for our senior debt securities issued under the 2004 senior debt indenture and the 2013 senior debt indenture, and subordinated debt securities issued under the subordinated debt indenture. If an actual or potential event of default occurs with respect to any of these securities, the trustee may be considered to have a conflicting interest for purposes of the Trust Indenture Act of 1939. In that case, the trustee must eliminate the conflict or may be required to resign under one or more of the indentures and we would be required to appoint a successor trustee. For this purpose, a “potential” event of default means an event that would be an event of default if the requirements for giving us default notice or for the default having to exist for a specific period of time were disregarded.

The recitals contained in this prospectus and in the debt securities shall be taken as statements of the Company and the trustee shall assume no responsibility for their correctness or the adequacy of any such statements. U.S. Bank National Association makes no representations or warranties regarding the debt securities or the adequacy or accuracy of this prospectus.

DESCRIPTION OF COMMON STOCK WE MAY OFFER

References to “Assurant,” the “Company,” “us,” “we” or “our” in this section mean Assurant, Inc., and do not include the subsidiaries of Assurant, Inc. Also, in this section, references to “holders” mean those who own shares of common stock registered in their own names, on the books that the registrar or we maintain for this purpose, and not those who own beneficial interests in shares registered in street name or in shares issued in book-entry form through one or more depositaries. Owners of beneficial interests in shares of common stock should read the section below entitled ��Legal Ownership and Book-Entry Issuance”.

The certificate of incorporation of Assurant, Inc. authorizes 800,000,000 shares of common stock, par value $0.01 per share. The following summary of the terms and provisions of our capital stock does not purport to be complete and is qualified in its entirety by reference to our amended and restated certificate of incorporation and amended and restated by-laws, forms of which have been filed as exhibits to the registration statement of which this prospectus forms a part, and applicable law. See “Where You Can Find More Information” for information about where you can obtain a copy of these documents.

General. All outstanding shares of common stock are, and all shares of common stock to be outstanding upon completion of the offering will be, fully-paid and nonassessable. As of January 15, 2021, we had 57,937,759 shares of common stock outstanding.

Dividends. Subject to any preferential rights of any outstanding series of preferred stock that our board of directors may create from time to time, including the 6.50% Series D Mandatory Convertible Preferred Stock, par value $1.00 per share (the “Series D Preferred Stock”), the holders of our common stock will be entitled to dividends as may be declared from time to time by the board of directors from funds available therefor.

Voting Rights. Each share of common stock entitles the holder thereof to one vote on all matters, including the election of directors, and, except as otherwise required by law or provided in any resolution adopted by our board of directors with respect to any series of preferred stock, the holders of the shares of our common stock will possess all voting power. Our certificate of incorporation does not provide for cumulative voting in the election of directors. Generally, all matters to be voted on by the stockholders must be approved by a majority of the votes cast, subject to state law and any voting rights granted to any of the holders of preferred stock.

Preemptive Rights. The holders of common stock do not have any preemptive rights. There are no subscription, redemption, conversion or sinking fund provisions with respect to the common stock.

Liquidation Rights. Upon dissolution, liquidation or winding-up of Assurant, subject to the rights of holders of any preferred stock outstanding or any other class or series of stock having preferential rights, the holders of shares of common stock will be entitled to receive our assets available for distribution proportionate to their pro rata ownership of the outstanding shares of common stock.

Anti-takeover Effects of Certain Provisions of the Certificate of Incorporation, By-Laws and Delaware General Corporation Law

The provisions of the Delaware General Corporation Law and our certificate of incorporation and by-laws summarized below may have the effect of discouraging, delaying or preventing hostile takeovers, including those that might result in a premium being paid over the market price of our common stock, and discouraging, delaying or preventing changes in control or management of our Company.

Certificate of Incorporation and By-Laws

Our certificate of incorporation, which provides for the issuance of preferred stock, may have the effect of delaying, deferring or preventing a change in control of our Company without further action by the stockholders

24

and may adversely affect the voting and other rights of the holders of shares of common stock. Further, our certificate of incorporation requires that any action required or permitted to be taken by our stockholders must be effected at a duly called annual or special meeting of our stockholders and may not be effected by a consent in writing. Special meetings of our stockholders may be called only by our Chief Executive Officer or by our board of directors pursuant to a resolution approved by the board of directors. In addition, our by-laws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors. These provisions may have the effect of delaying, deferring or preventing a change in control.

Issuance of Preferred Stock. Our board of directors has the authority, without further action of our stockholders, to issue up to 200,000,000 shares of preferred stock, par value $1.00 per share, in one or more series and to fix the powers, preferences, rights and qualifications, limitations or restrictions thereof. The issuance of preferred stock on various terms could adversely affect the holders of common stock. The potential issuance of preferred stock may discourage bids for shares of our common stock at a premium over the market price of our common stock, may adversely affect the market price of shares of our common stock and may discourage, delay or prevent a change of control of Assurant.

The anti-takeover and other provisions of our certificate of incorporation and by-laws could discourage potential acquisition proposals and could delay or prevent a change in control. These provisions are intended to enhance the likelihood of continuity and stability in the composition of the board of directors and in the policies formulated by the board of directors and to discourage certain types of transactions that may involve an actual or threatened change of control. These provisions are designed to reduce our vulnerability to an unsolicited acquisition proposal. The provisions also are intended to discourage certain tactics that may be used in proxy fights. However, these provisions could have the effect of discouraging others from making tender offers for our shares and, as a consequence, they also may inhibit fluctuations in the market price of our shares that could result from actual or rumored takeover attempts. These provisions also may have the effect of preventing changes in our management.

Delaware General Corporation Law

We are subject to Section 203 of the Delaware General Corporation Law, which we refer to as “Section 203”. In general, Section 203 prevents a person who owns 15% or more of our outstanding voting stock, an “interested stockholder,” from engaging in some business combinations, as described below, with us for three years following the time that that person becomes an interested stockholder unless one of the following occurs:

For purposes of Section 203, the term “business combinations” includes mergers, consolidations, asset sales or other transactions that result in a financial benefit to the interested stockholder and transactions that would increase the interested stockholder’s proportionate share ownership of our Company.

25

Under some circumstances, Section 203 makes it more difficult for an interested stockholder to effect various business combinations with us for a period of three years after the stockholder becomes an interested stockholder. Although our stockholders have the right to exclude us from the restrictions imposed by Section 203, they have not done so. Section 203 may encourage companies interested in acquiring us to negotiate in advance with the board of directors, because the requirement stated above regarding stockholder approval would be avoided if a majority of the directors approves, prior to the time the party became an interested stockholder, either the business combination or the transaction which results in the stockholder becoming an interested stockholder.

Listing

Our common stock is listed on the New York Stock Exchange under the trading symbol “AIZ”.

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Computershare, P.O. Box 505000, Louisville, KY 40233.

DESCRIPTION OF PREFERRED STOCK AND

DEPOSITARY SHARES REPRESENTING PREFERRED STOCK WE MAY OFFER

References to “Assurant,” the “Company,” “us,” “we” or “our” in this section mean Assurant, Inc., and do not include the subsidiaries of Assurant, Inc. Also, in this section, references to “holders” mean those who own shares of preferred stock or depositary shares, as the case may be, registered in their own names, on the books that the registrar or we maintain for this purpose, and not those who own beneficial interests in shares registered in street name or in shares issued in book-entry form through one or more depositaries. When we refer to “you” in this section, we mean all purchasers of the securities being offered by this prospectus, whether they are the holders or only indirect owners of those securities. Owners of beneficial interests in shares of preferred stock or depositary shares should read the section below entitled “Legal Ownership and Book-Entry Issuance”.

General

We may issue preferred stock in one or more series. We may also “reopen” a previously issued series of preferred stock and issue additional preferred stock of that series. In addition, we may issue preferred stock together with other preferred stock, debt securities, warrants, stock purchase contracts and common stock in the form of units as described below under “Description of Units We May Offer”. This section summarizes terms of the preferred stock that apply generally to all series. The description of most of the financial and other specific terms of your series will be in your prospectus supplement. Those terms may vary from the terms described here.

Because this section is a summary, it does not describe every aspect of the preferred stock and any related depositary shares. As you read this section, please remember that the specific terms of your series of preferred stock and any related depositary shares as described in your prospectus supplement will supplement and, if applicable, modify or replace the general terms described in this section. If there are differences between your prospectus supplement and this prospectus, your prospectus supplement will control. Thus, the statements we make in this section may not apply to your series of preferred stock or any related depositary shares.

Reference to a series of preferred stock means all of the shares of preferred stock issued as part of the same series under a certificate of designations filed as part of our amended and restated certificate of incorporation. Reference to your prospectus supplement means the prospectus supplement describing the specific terms of the preferred stock and any related depositary shares you purchase. The terms used in your prospectus supplement will have the meanings described in this prospectus, unless otherwise specified.

Authorized and Outstanding Preferred Stock

Our board of directors has the authority, without further action of our stockholders, to issue up to 200,000,000 shares of preferred stock, par value $1.00 per share, in one or more series and to fix the powers, preferences, rights and qualifications, limitations or restrictions thereof, which may include dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences and the number of shares constituting any series or the designations of the series.

At January 15, 2021, 2,875,000 shares of our preferred stock were outstanding.

Series D Mandatory Convertible Preferred Stock

Holders of our Series D Preferred Stock are entitled to receive dividends on a cumulative basis when, as and if declared by the Company’s board of directors, at an annual rate of 6.50% per share per annum multiplied by the $100 per share liquidation price. Dividends may be paid in cash or, subject to certain limitations, in shares of the Company’s common stock or, in any combination of cash and shares of common stock. If declared, all dividends are payable in arrears on a quarterly basis. Any dividend that is not paid on a specified dividend payment date with respect to a share of such Preferred Stock shall be deemed added to the liquidation price of such share for purposes of computing the future dividends on such share, until such delinquent dividend has been paid.

27

Unless converted or redeemed earlier in accordance with the terms of the Certificate of Designations of 6.50% Series D Mandatory Convertible Preferred Stock, each share of Series D Preferred Stock will convert automatically on the mandatory conversion date, which is expected to be March 15, 2021, into between 0.9391 and 1.1269 shares of the Company’s common stock, subject to customary anti-dilution adjustments. The number of shares of common stock issuable upon conversion will be determined based on the average volume weighted average price per share of common stock over the 20 consecutive trading day period beginning on, and including, the 21st scheduled trading day immediately prior to March 15, 2021.

In addition, as we described below under “—Fractional or Multiple Shares of Preferred Stock Issued as Depositary Shares”, we may, at our option, instead of offering whole individual shares of any series of preferred stock, offer depositary shares evidenced by depositary receipts, each representing a fraction of a share or some multiple of shares of the particular series of preferred stock issued and deposited with a depositary. The fraction of a share or multiple of shares of preferred stock which each depositary share represents will be stated in the prospectus supplement relating to any series of preferred stock offered through depositary shares.

The rights of holders of preferred stock may be adversely affected by the rights of holders of preferred stock that may be issued in the future. Our board of directors may cause shares of preferred stock to be issued in public or private transactions for any proper corporate purpose. Examples of proper corporate purposes include issuances to obtain additional financing for acquisitions and issuances to officers, directors and employees under their respective benefit plans. Our issuance of shares of preferred stock may have the effect of discouraging or making an acquisition more difficult.

Preferred stock will be fully paid and nonassessable when issued, which means that our holders will have paid their purchase price in full and that we may not ask them to surrender additional funds. Unless otherwise provided in your prospectus supplement, holders of preferred stock will not have preemptive or subscription rights to acquire more stock of Assurant.

The transfer agent, registrar, dividend disbursing agent and redemption agent for shares of each series of preferred stock will be named in the prospectus supplement relating to that series.

Form of Preferred Stock

We may issue preferred stock in book-entry form. Preferred stock in book-entry form will be represented by a global security registered in the name of a depositary, which will be the holder of all the shares of preferred stock represented by the global security. Those who own beneficial interests in shares of preferred stock will do so through participants in the depositary’s system, and the rights of these indirect owners will be governed solely by the applicable procedures of the depositary and its participants. However, beneficial owners of any preferred stock in book-entry form will have the right to obtain their shares in non-global form. We describe book-entry securities below under “Legal Ownership and Book-Entry Issuance”. All preferred stock will be issued in registered form.

Overview of Remainder of this Description

The remainder of this description summarizes:

28

Preferred Stockholders’ Rights

Rank

Shares of each series of preferred stock will rank senior to our common stock with respect to dividends and distributions of assets. However, we will generally be able to pay dividends and distributions of assets to holders of our preferred stock only if we have satisfied our obligations on our indebtedness then due and payable.

Dividends

Holders of each series of preferred stock will be entitled to receive cash dividends when, as and if declared by our board of directors, from funds legally available for the payment of dividends. The rates and dates of payment of dividends for each series of preferred stock will be stated in your prospectus supplement. Dividends will be payable to holders of record of preferred stock as they appear on our books on the record dates fixed by our board of directors. Dividends on any series of preferred stock may be cumulative or noncumulative, as set forth in the prospectus supplement.

Redemption

If specified in your prospectus supplement, a series of preferred stock may be redeemable at any time, in whole or in part, at our option or the holder’s, and may be redeemed mandatorily.

Any restriction on the repurchase or redemption by us of our preferred stock while there is an arrearage in the payment of dividends will be described in your prospectus supplement.

Any partial redemptions of preferred stock will be made in a way that our board of directors decides is equitable.

Unless we default in the payment of the redemption price, dividends will cease to accrue after the redemption date on shares of preferred stock called for redemption and all rights of holders of these shares, including voting rights, will terminate except for the right to receive the redemption price.

Conversion or Exchange Rights

Our prospectus supplement relating to any series of preferred stock that is convertible, exercisable or exchangeable will state the terms on which shares of that series are convertible into or exercisable or exchangeable for shares of common stock, another series of preferred stock or other of our securities or securities of third parties.

Liquidation Preference

Upon any voluntary or involuntary liquidation, dissolution or winding up of Assurant, holders of each series of preferred stock will be entitled to receive distributions upon liquidation in the amount described in your prospectus supplement, plus an amount equal to any accrued and unpaid dividends. These distributions will be made before any distribution is made on our common stock. If the liquidation amounts payable relating to the preferred stock of any series and any other parity securities ranking on a parity regarding liquidation rights are not paid in full, the holders of the preferred stock of that series and the other parity securities will share in any distribution of our available assets on a ratable basis in proportion to the full liquidation preferences of each security. Holders of our preferred stock will not be entitled to any other amounts from us after they have received their full liquidation preference and accrued and unpaid dividends.

Voting Rights

The holders of preferred stock of each series will have no voting rights, except:

29

Fractional or Multiple Shares of Preferred Stock Issued as Depositary Shares

We may choose to offer fractional shares or some multiple of shares of our preferred stock, rather than whole individual shares. If we decide to do so, we will issue the preferred stock in the form of depositary shares. Each depositary share would represent a fraction or multiple of a share of the preferred stock and would be evidenced by a depositary receipt, as further described in the prospectus supplement relating to any series of preferred stock offered through depositary shares.

Deposit Agreement

We will deposit the shares of preferred stock to be represented by depositary shares under a deposit agreement. The parties to the deposit agreement will be:

Each holder of a depositary share will be entitled to all the rights and preferences of the underlying preferred stock, including, where applicable, dividend, voting, redemption, conversion and liquidation rights, in proportion to the applicable fraction or multiple of a share of preferred stock represented by the depositary share. The depositary shares will be evidenced by depositary receipts issued under the deposit agreement. The depositary receipts will be distributed to those persons purchasing the fractional or multiple shares of preferred stock. A depositary receipt may evidence any number of whole depositary shares. The depositary for the depositary shares may charge certain fees for holding the preferred stock on behalf of the holders of the depositary shares or in connection with certain transfers, redemptions, dividend payments, distributions or other transactions involving the depositary shares.

We will file the deposit agreement, including the form of depositary receipt, with the SEC, either as an exhibit to the registration statement of which this prospectus forms a part or as an exhibit to a current report on Form 8-K.

Dividends and Other Distributions

The preferred stock depositary will distribute any cash dividends or other cash distributions received in respect of the deposited preferred stock to the record holders of depositary shares relating to the underlying preferred stock in proportion to the number of depositary shares owned by the holders. The preferred stock depositary will distribute any property received by it other than cash to the record holders of depositary shares entitled to those distributions, unless it determines that the distribution cannot be made proportionally among those holders or that it is not feasible to make a distribution. In that event, the preferred stock depositary may, with our approval, sell the property and distribute the net proceeds from the sale to the holders of the depositary shares in proportion to the number of depositary shares they own.

The amounts distributed to holders of depositary shares will be reduced by any amounts required to be withheld by the preferred stock depositary or by us on account of taxes or other governmental charges.

Redemption of Preferred Stock

If we redeem preferred stock represented by depositary shares, the preferred stock depositary will redeem the depositary shares from the proceeds it receives from the redemption. The preferred stock depositary will redeem the depositary shares at a price per share equal to the applicable fraction or multiple of the redemption price per share of preferred stock. Whenever we redeem shares of preferred stock held by the preferred stock

30

depositary, the preferred stock depositary will redeem as of the same date the number of depositary shares representing the redeemed shares of preferred stock. If fewer than all the depositary shares are to be redeemed, the preferred stock depositary will select the depositary shares to be redeemed by lot or ratably or by any other equitable method it chooses.

After the date fixed for redemption, the depositary shares called for redemption will no longer be deemed to be outstanding, and all rights of the holders of those shares will cease, including voting rights, except the right to receive the amount payable and any other property to which the holders were entitled upon the redemption. To receive this amount or other property, the holders must surrender the depositary receipts evidencing their depositary shares to the preferred stock depositary. Any funds that we deposit with the preferred stock depositary for any depositary shares that the holders fail to redeem will be returned to us after a period of two years from the date we deposit the funds.

Withdrawal of Preferred Stock

Unless the related depositary shares have previously been called for redemption, any holder of depositary shares may receive the number of whole shares of the related series of preferred stock and any money or other property represented by those depositary receipts after surrendering the depositary receipts at the corporate trust office of the preferred stock depositary, paying any taxes, charges and fees provided for in the deposit agreement and complying with any other requirement of the deposit agreement. Holders of depositary shares making these withdrawals will be entitled to receive whole shares of preferred stock, but holders of whole shares of preferred stock will not be entitled to deposit that preferred stock under the deposit agreement or to receive depositary receipts for that preferred stock after withdrawal. If the depositary shares surrendered by the holder in connection with withdrawal exceed the number of depositary shares that represent the number of whole shares of preferred stock to be withdrawn, the preferred stock depositary will deliver to that holder at the same time a new depositary receipt evidencing the excess number of depositary shares.

Voting Deposited Preferred Stock

When the preferred stock depositary receives notice of any meeting at which the holders of any series of deposited preferred stock are entitled to vote, the preferred stock depositary will mail the information contained in the notice to the record holders of the depositary shares relating to the applicable series of preferred stock. Each record holder of the depositary shares on the record date, which will be the same date as the record date for the preferred stock, may instruct the preferred stock depositary to vote the amount of the preferred stock represented by the holder’s depositary shares. To the extent possible, the preferred stock depositary will vote the amount of the series of preferred stock represented by depositary shares in accordance with the instructions it receives. We will agree to take all reasonable actions that the preferred stock depositary determines are necessary to enable the preferred stock depositary to vote as instructed. If the preferred stock depositary does not receive specific instructions from the holders of any depositary shares representing a series of preferred stock, the preferred stock depositary will vote all shares of that series in proportion to the instructions received.

Conversion of Preferred Stock

If our prospectus supplement relating to the depositary shares says that the deposited preferred stock is convertible into or exercisable or exchangeable for common stock, preferred stock of another series or other securities, or debt or equity securities of one or more third parties, our depositary shares, as such, will not be convertible into or exercisable or exchangeable for any securities. Rather, any holder of the depositary shares may surrender the related depositary receipts to the preferred stock depositary with written instructions to instruct us to cause conversion, exercise or exchange of our preferred stock represented by the depositary shares into or for whole shares of common stock, shares of another series of preferred stock or other of our securities or securities of the relevant third party, as applicable. Upon receipt of those instructions and any amounts payable by the holder in connection with the conversion, exercise or exchange, we will cause the conversion, exercise or

31

exchange using the same procedures as those provided for conversion, exercise or exchange of the deposited preferred stock. If only some of the depositary shares are to be converted, exercised or exchanged, a new depositary receipt or receipts will be issued for any depositary shares not to be converted, exercised or exchanged.

Form of Depositary Shares

We may issue depositary shares in book-entry form. Depositary shares in book-entry form will be represented by a global security registered in the name of a depositary, which will be the holder of all the depositary shares represented by the global security. Those who own beneficial interests in depositary shares will do so through participants in the depositary’s system, and the rights of these indirect owners will be governed solely by the applicable procedures of the depositary and its participants. However, beneficial owners of any depositary shares in book-entry form will have the right to obtain their shares in non-global form. We describe book-entry securities below under “Legal Ownership and Book-Entry Issuance”. All depositary shares will be issued in registered form.

32

DESCRIPTION OF WARRANTS WE MAY OFFER

References to “Assurant,” the “Company,” “us,” “we” or “our” in this section mean Assurant, Inc., and do not include the subsidiaries of Assurant, Inc. Also, in this section, references to “holders” mean those who own warrants registered in their own names, on the books that the registrar or we maintain for this purpose, and not those who own beneficial interests in warrants registered in street name or in warrants issued in book-entry form through one or more depositaries. Owners of beneficial interests in warrants should read the section below entitled “Legal Ownership and Book-Entry Issuance”.

General

We may issue warrants to purchase our senior debt securities, subordinated debt securities, preferred stock, depositary shares, common stock, any securities of a third party or any combination of these securities, and these warrants may be issued independently or together with any underlying securities and may be attached or separate from those underlying securities. We will issue each series of warrants under a separate warrant agreement to be entered into between us and a warrant agent. The warrant agent will act solely as our agent in connection with the warrants of such series and will not assume any obligation or relationship of agency for or with holders or beneficial owners of warrants.

The following outlines some of the general terms and provisions of the warrants. Further terms of the warrants and the applicable warrant agreement will be stated in the applicable prospectus supplement. The following description and any description of the warrants in a prospectus supplement may not be complete and is subject to and qualified in its entirety by reference to the terms and provisions of the warrant agreement, a form of which will be filed as an exhibit to the registration statement that contains this prospectus or as an exhibit to a current report on Form 8-K.

A Prospectus Supplement Will Describe the Specific Terms of Warrants

The applicable prospectus supplement will describe the terms of any warrants that we may offer, including the following:

33

We may also issue warrants, on terms to be determined at the time of sale, for the purchase or sale of, or whose cash value is determined by reference to the performance, level or value of, one or more of the following:

We refer to this type of warrant as a universal warrant. We refer to each property described above as a warrant property.

We may satisfy our obligations, if any, and the holder of a universal warrant may satisfy its obligations, if any, with respect to any universal warrants by delivering:

The applicable prospectus supplement will describe what we may deliver to satisfy our obligations, if any, and what the holder of a universal warrant may deliver to satisfy its obligations, if any, with respect to any universal warrants.

Warrant certificates may be exchanged for new warrant certificates of different denominations, and warrants may be exercised at the warrant agent’s corporate trust office or any other office indicated in the applicable prospectus supplement. Prior to the exercise of their warrants, holders of warrants exercisable for debt securities will not have any of the rights of holders of the debt securities purchasable upon such exercise and will not be entitled to payments of principal, or premium, if any, or interest, if any, on the debt securities purchasable upon such exercise. Prior to the exercise of their warrants, holders of warrants exercisable for shares of preferred stock or common stock will not have any rights of holders of the preferred stock or common stock purchasable upon such exercise and will not be entitled to dividend payments, if any, or voting rights of the preferred stock or common stock purchasable upon such exercise.

Exercise of Warrants

A warrant will entitle the holder to purchase for cash an amount of securities at an exercise price that will be stated in, or that will be determinable as described in, the applicable prospectus supplement. Warrants may be exercised at any time up to the close of business on the expiration date set forth in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void.

34

Warrants may be exercised as set forth in the applicable prospectus supplement. Upon receipt of payment and the warrant certificate properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the prospectus supplement, we will, as soon as practicable, forward the securities purchasable upon such exercise. If less than all of the warrants represented by such warrant certificate are exercised, a new warrant certificate will be issued for the remaining warrants.

Enforceability of Rights; Governing Law

The holders of warrants, without the consent of the warrant agent, may, on their own behalf and for their own benefit, enforce, and may institute and maintain any suit, action or proceeding against us to enforce their rights to exercise and receive the securities purchasable upon exercise of their warrants. Unless otherwise stated in the prospectus supplement, each issue of warrants and the applicable warrant agreement will be governed by the laws of the State of New York.

DESCRIPTION OF STOCK PURCHASE CONTRACTS WE MAY OFFER

References to “Assurant,” the “Company,” “us,” “we” or “our” in this section mean Assurant, Inc., and do not include the subsidiaries of Assurant, Inc. Also, in this section, references to “holders” mean those who own stock purchase contracts registered in their own names, on the books that the registrar or we maintain for this purpose, and not those who own beneficial interests in stock purchase contracts registered in street name or in stock purchase contracts issued in book-entry form through one or more depositaries. Owners of beneficial interests in stock purchase contracts should read the section below entitled “Legal Ownership and Book-Entry Issuance”.

The applicable prospectus supplement will describe the terms of any stock purchase contracts that we may offer. The following description and any description of stock purchase contracts in the applicable prospectus supplement may not be complete and is subject to, and is qualified in its entirety by, reference to the stock purchase contract agreement and, if applicable, collateral arrangements and depositary arrangements relating to such stock purchase contracts that we will file with the SEC as an exhibit to the registration statement that contains this prospectus or as an exhibit to a current report on Form 8-K.

We may issue stock purchase contracts, representing contracts obligating holders to purchase from or sell to us, and obligating us to purchase from or sell to the holders, a specified or variable number of shares of our common stock, preferred stock or depositary shares, as applicable, at a future date or dates. The price per share of common stock, preferred stock or depositary shares, as applicable, may be fixed at the time the stock purchase contracts are issued or may be determined by reference to a specific formula contained in the stock purchase contracts. We may issue stock purchase contracts in such amounts and in as many distinct series as we wish.

The stock purchase contracts may be issued separately or as part of units, which we refer to in this prospectus as units. Units may consist of a stock purchase contract and beneficial interests in other securities described in this prospectus or of third parties, securing the holders’ obligations to purchase from or sell shares to us under the stock purchase contracts. These other securities may consist of our debt securities, preferred stock, common stock, depositary shares, warrants or securities of third parties, including U.S. Treasury securities. The stock purchase contracts may require us to make periodic payments to the holders of the stock purchase contracts or vice versa, and these payments may be unsecured or prefunded on some basis. The stock purchase contracts may require holders to secure their obligations under those contracts in a specified manner.

The applicable prospectus supplement may contain, where applicable, the following information about the stock purchase contracts issued under it:

36

DESCRIPTION OF UNITS WE MAY OFFER

References to “Assurant,” the “Company,” “ us,” “we” or “our” in this section mean Assurant, Inc., and do not include the subsidiaries of Assurant, Inc. Also, in this section, references to “holders” mean those who own units registered in their own names, on the books that the registrar or we maintain for this purpose, and not those who own beneficial interests in units registered in street name or in units issued in book-entry form through one or more depositaries. Owners of beneficial interests in units should read the section below entitled “Legal Ownership and Book-Entry Issuance”.

The applicable prospectus supplement will describe the terms of any units. The following description and any description of units in the applicable prospectus supplement may not be complete and is subject to, and is qualified in its entirety by reference to, the unit agreement and, if applicable, collateral arrangements and depositary arrangements relating to such units that we will file with the SEC as an exhibit to the registration statement that contains this prospectus or as an exhibit to a current report on Form 8-K.

We may issue units comprised of one or more of the other securities described in this prospectus in any combination. Each unit may also include debt obligations of third parties, such as U.S. Treasury securities. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date.

The applicable prospectus supplement may describe:

37

LEGAL OWNERSHIP AND BOOK-ENTRY ISSUANCE

References to Assurant,” the “Company,” “us,” “we” or “our” in this section means Assurant, Inc. In this section, we describe special considerations that will apply to registered securities issued in global — i.e., book-entry — form. First we describe the difference between legal ownership and indirect ownership of registered securities. Then we describe special provisions that apply to global securities.

Who is the Legal Owner of a Registered Security?

Each debt security, warrant, stock purchase contract, unit or share of preferred or common stock in registered form will be represented either by a certificate issued in definitive form to a particular investor or by one or more global securities representing such securities. We refer to those who have securities registered in their own names, on the books that we or the trustee, warrant agent or other agent maintain for this purpose, as the “holders” of those securities. These persons are the legal holders of the securities. We refer to those who, indirectly through others, own beneficial interests in securities that are not registered in their own names as indirect owners of those securities. As we discuss below, indirect owners are not legal holders, and investors in securities issued in book-entry form or in street name will be indirect owners.

Book-Entry Owners

Unless otherwise noted in your prospectus supplement, we will issue each security in book-entry form only. This means securities will be represented by one or more global securities registered in the name of a financial institution that holds them as depositary on behalf of other financial institutions that participate in the depositary’s book-entry system. These participating institutions, in turn, hold beneficial interests in the securities on behalf of themselves or their customers.

Under each indenture, warrant agreement, stock purchase contract, unit agreement or depositary agreement, only the person in whose name a security is registered is recognized as the holder of that security. Consequently, for securities issued in global form, we will recognize only the depositary as the holder of the securities and we will make all payments on the securities, including deliveries of any property other than cash, to the depositary. The depositary passes along the payments it receives to its participants, which in turn pass the payments along to their customers who are the beneficial owners. The depositary and its participants do so under agreements they have made with one another or with their customers; they are not obligated to do so under the terms of the securities.

As a result, investors will not own securities directly. Instead, they will own beneficial interests in a global security, through a bank, broker or other financial institution that participates in the depositary’s book-entry system or holds an interest through a participant. As long as the securities are issued in global form, investors will be indirect owners, and not holders, of the securities.

Street Name Owners

We may terminate an existing global security or issue securities initially in non-global form. In these cases, investors may choose to hold their securities in their own names or in street name. Securities held by an investor in street name would be registered in the name of a bank, broker or other financial institution that the investor chooses, and the investor would hold only a beneficial interest in those securities through an account he or she maintains at that institution.

For securities held in street name, we will recognize only the intermediary banks, brokers and other financial institutions in whose names the securities are registered as the holders of those securities and we will make all payments on those securities, including deliveries of any property other than cash, to them. These institutions pass along the payments they receive to their customers who are the beneficial owners, but only because they agree to do so in their customer agreements or because they are legally required to do so. Investors who hold securities in street name will be indirect owners, not holders, of those securities.

38

Legal Holders

Our obligations, as well as the obligations of the trustee under any indenture and the obligations, if any, of any warrant agents and unit agents and any other third parties employed by us, the trustee or any of those agents, run only to the holders of the securities. We do not have obligations to investors who hold beneficial interests in global securities, in street name or by any other indirect means. This will be the case whether an investor chooses to be an indirect owner of a security or has no choice because we are issuing the securities only in global form.

For example, once we make a payment or give a notice to the holder, we have no further responsibility for that payment or notice even if that holder is required, under agreements with depositary participants or customers or by law, to pass it along to the indirect owners but does not do so. Similarly, if we want to obtain the approval of the holders for any purpose — for example, to amend the indenture for a series of debt securities or warrants or the warrant agreement for a series of warrants or to relieve us of the consequences of a default or of our obligation to comply with a particular provision of an indenture or warrant agreement — we would seek the approval only from the holders, and not the indirect owners, of the relevant securities. Whether and how the holders contact the indirect owners is up to the holders.

When we refer to “you” in this prospectus, we mean all purchasers of the securities being offered by this prospectus, whether they are the holders or indirect owners of those securities. When we refer to “your securities” in this prospectus, we mean the securities in which you will hold a direct or indirect interest.

Special Considerations for Indirect Owners

If you hold securities through a bank, broker or other financial institution, either in book-entry form or in street name, you should check with your own institution to find out:

What is a Global Security?

Unless otherwise noted in the applicable prospectus or pricing supplement, we will issue each security in book-entry form only. Each security issued in book-entry form will be represented by a global security that we deposit with and register in the name of one or more financial institutions or clearing systems, or their nominees, which we select. A financial institution or clearing system that we select for any security for this purpose is called the “depositary” for that security. A security will usually have only one depositary but it may have more. Each series of securities will have one or more of the following as the depositaries:

39

The depositaries named above may also be participants in one another’s systems. Thus, for example, if DTC is the depositary for a global security, investors may hold beneficial interests in that security through Euroclear or Clearstream, as DTC participants. The depositary or depositaries for your securities will be named in your prospectus supplement; if none is named, the depositary will be DTC.

A global security may represent one or any other number of individual securities. Generally, all securities represented by the same global security will have the same terms. We may, however, issue a global security that represents multiple securities of the same kind, such as debt securities, that have different terms and are issued at different times. We call this kind of global security a master global security. Your prospectus supplement will not indicate whether your securities are represented by a master global security.

A global security may not be transferred to or registered in the name of anyone other than the depositary or its nominee, unless special termination situations arise. We describe those situations below under “— Holder’s Option to Obtain a Non-Global Security: Special Situations When a Global Security Will Be Terminated”. As a result of these arrangements, the depositary, or its nominee, will be the sole registered owner and holder of all securities represented by a global security, and investors will be permitted to own only indirect interests in a global security. Indirect interests must be held by means of an account with a broker, bank or other financial institution that in turn has an account with the depositary or with another institution that does. An investor whose security is represented by a global security will not be a holder of the security, but only an indirect owner of an interest in the global security.

If the prospectus supplement for a particular security indicates that the security will be issued in global form only, then the security will be represented by a global security at all times unless and until the global security is terminated. We describe the situations in which this can occur below under “— Holder’s Option to Obtain a Non-Global Security: Special Situations When a Global Security Will Be Terminated”. If termination occurs, we may issue the securities through another book-entry clearing system or decide that the securities may no longer be held through any book-entry clearing system.

Special Considerations for Global Securities

As an indirect owner, an investor’s rights relating to a global security will be governed by the account rules of the depositary and those of the investor’s bank, broker, financial institution or other intermediary through which it holds its interest (e.g., Euroclear or Clearstream, if DTC is the depositary), as well as general laws relating to securities transfers. We do not recognize this type of investor or any intermediary as a holder of securities and instead deal only with the depositary that holds the global security.

If securities are issued only in the form of a global security, an investor should be aware of the following:

40

Holder’s Option to Obtain a Non-Global Security: Special Situations When a Global Security Will Be Terminated

If we issue any series of securities in book-entry form but we choose to give the beneficial owners of that series the right to obtain non-global securities, any beneficial owner entitled to obtain non-global securities may do so by following the applicable procedures of the depositary, any transfer agent or registrar for that series and that owner’s bank, broker or other financial institution through which that owner holds its beneficial interest in the securities. If you are entitled to request a non-global certificate and wish to do so, you will need to allow sufficient lead time to enable us or our agent to prepare the requested certificate.

In addition, in a few special situations described below, a global security will be terminated and interests in it will be exchanged for certificates in non-global form representing the securities it represented. After that exchange, the choice of whether to hold the securities directly or in street name will be up to the investor. Investors must consult their own banks, brokers or other financial institutions to find out how to have their interests in a global security transferred on termination to their own names, so that they will be holders. We have described the rights of holders and street name investors above under “— Who is the Legal Owner of a Registered Security?”

The special situations for termination of a global security are as follows:

41

If a global security is terminated, only the depositary, and not we, the trustee for any debt securities, the warrant agent for any warrants, the unit agent for any units or any other third party retained to provide securities-related services, is responsible for deciding the names of the institutions in whose names the securities represented by the global security will be registered and, therefore, who will be the holders of those securities.

Considerations Relating to DTC

DTC has informed 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 DTC participants deposit with DTC. DTC also facilitates the settlement among DTC participants of securities transactions, such as transfers and pledges in deposited securities through electronic computerized book-entry changes in DTC participants’ accounts, thereby eliminating the need for physical movement of certificates. DTC participants include securities brokers and dealers, banks, trust companies and clearing corporations, and may include other organizations. DTC is owned by a number of its DTC participants and by the New York Stock Exchange, Inc., the American Stock Exchange, LLC and the National Association of Securities Dealers, Inc. Indirect access to the DTC system also is available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly. The rules applicable to DTC and DTC participants are on file with the SEC.

Purchases of securities within the DTC system must be made by or through DTC participants, which will receive a credit for the securities on DTC’s records. Transfers of ownership interests in the securities are to be accomplished by entries made on the books of participants acting on behalf of beneficial owners.

Redemption notices will be sent to DTC’s nominee, Cede & Co., as the registered holder of the securities. If less than all of the securities are being redeemed, DTC will determine the amount of the interest of each direct participant to be redeemed in accordance with its then current procedures.

In instances in which a vote is required, neither DTC nor Cede & Co. will itself consent or vote with respect to the securities. Under its usual procedures, DTC would mail an omnibus proxy to the relevant trustee 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 such securities are credited on the record date (identified in a listing attached to the omnibus proxy).

Distribution payments on the securities will be made by the relevant trustee to DTC. DTC’s usual practice is to credit direct participants’ accounts on the relevant payment date in accordance with their respective holdings shown on DTC’s records unless DTC has reason to believe that it will not receive payments on such payment date. Payments by participants to beneficial owners will be governed by standing instructions and customary practices and will be the responsibility of such participants and not of DTC, the relevant trustee or us, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of distributions to DTC is the responsibility of the relevant trustee, and disbursements of such payments to the beneficial owners are the responsibility of direct and indirect participants.

The information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that we believe to be accurate, but we assume no responsibility for the accuracy thereof. We do not have any responsibility for the performance by DTC or its participants of their respective obligations as described herein or under the rules and procedures governing their respective operations.

Considerations Relating to Euroclear and Clearstream

Euroclear and Clearstream are securities clearance systems in Europe. Both systems clear and settle securities transactions between their participants through electronic, book-entry delivery of securities against payment.

42

Euroclear and Clearstream may be depositaries for a global security. In addition, if DTC is the depositary for a global security, Euroclear and Clearstream may hold interests in the global security as participants in DTC.

As long as any global security is held by Euroclear or Clearstream, as depositary, you may hold an interest in the global security only through an organization that participates, directly or indirectly, in Euroclear or Clearstream. If Euroclear or Clearstream is the depositary for a global security and there is no depositary in the United States, you will not be able to hold interests in that global security through any securities clearance system in the United States.

Payments, deliveries, transfers, exchanges, notices and other matters relating to the 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. We have no control over those systems or their participants and we take no responsibility for their activities. Transactions between participants in Euroclear or Clearstream, on one hand, and participants in DTC, on the other hand, when DTC is the depositary, would also be subject to DTC’s rules and procedures.

Special Timing Considerations Relating to Transactions in Euroclear and Clearstream

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

43

PLAN OF DISTRIBUTION

We may sell the offered securities in and outside the United States (1) through underwriters or dealers, (2) directly to purchasers or (3) through agents or through a combination of any of these methods of sale. The prospectus or pricing supplement will set forth the following information:

In addition, we may issue the securities as a dividend or distribution or in a subscription rights offering to our existing security holders. In some cases, we or dealers acting with us or on our behalf may also purchase securities and reoffer them to the public by one or more of the methods described above. This prospectus may be used in connection with any offering of our securities through any of these methods or other methods described in the applicable prospectus supplement.

If we offer securities in a subscription rights offering to our existing security holders, we may enter into a standby underwriting agreement with dealers, acting as standby underwriters. We may pay the standby underwriters a commitment fee for the securities they commit to purchase on a standby basis. If we do not enter into a standby underwriting arrangement, we may retain a dealer-manager to manage a subscription rights offering for us.

Sale Through Underwriters or Dealers

If we use underwriters in the sale, the underwriters will acquire the securities for their own account. The underwriters may resell the securities from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. Underwriters may offer securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. Underwriters may sell the securities to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters or commissions from the purchasers for whom they act as agents. Unless we inform you otherwise in the prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to certain conditions, and the underwriters will be obligated to purchase all the offered securities if they purchase any of them. 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.

During and after an offering through underwriters, the underwriters may purchase and sell the securities in the open market. These transactions may include overallotment and stabilizing transactions and purchases to cover syndicate short positions created in connection with the offering. The underwriters may also impose a penalty bid, in which selling concessions allowed to syndicate members or other broker-dealers for the offered securities sold for their account may be reclaimed by the syndicate if such offered securities are repurchased by the syndicate in stabilizing or covering transactions. These activities may stabilize, maintain or otherwise affect the market price of the offered securities, which may be higher than the price that might otherwise prevail in the open market. If commenced, these activities may be discontinued at any time.

44

If we use dealers in the sale of securities, we will sell the securities to them as principals. They may then resell those securities to the public at varying prices determined by the dealers at the time of resale. The dealers participating in any sale of the securities may be deemed to be underwriters within the meaning of the Securities Act of 1933 with respect to any sale of those securities. We will include in the prospectus supplement the names of the dealers, the terms of the transaction and the nature of the underwriter’s obligation.

Direct Sales and Sales Through Agents

We may sell the securities directly. In that event, no underwriters or agents would be involved. We may also sell the securities through agents we designate from time to time. In the prospectus supplement, we will name any agent involved in the offer or sale of the offered securities, and we will describe any commissions payable by us to the agent. Unless we inform you otherwise in the prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.

We may sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act of 1933 with respect to any sale of those securities. We will describe the terms of any such sales in the prospectus supplement.

Delayed Delivery Contracts

If we so indicate in the prospectus supplement, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase securities from us at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery on a specified date in the future. The contracts would be subject only to those conditions described in the prospectus supplement. The prospectus supplement will describe the commission payable for solicitation of those contracts.

Remarketing

We may offer and sell any of the securities in connection with a remarketing upon their purchase, in accordance with a redemption or repayment by their terms or otherwise, by one or more remarketing firms acting as principals for their own accounts or as our agents. We will identify any remarketing firm, the terms of any remarketing agreement and the compensation to be paid to the remarketing firm in the prospectus supplement. Remarketing firms may be deemed underwriters under the Securities Act.

Sales by Selling Securityholders

Selling securityholders may use this prospectus in connection with resales of the securities. The applicable prospectus supplement will identify the selling securityholders and the terms of the securities. Selling securityholders may be deemed to be underwriters in connection with the securities they resell and any profits on the sales may be deemed to be underwriting discounts and commissions under the Securities Act. The selling securityholders will receive all the proceeds from the sale of the securities. We will not receive any proceeds from sales by selling securityholders.

Derivative Transactions

We may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third parties may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of shares, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of shares.

45

We or one of our affiliates may loan or pledge securities to a financial institution or other third party that in turn may sell the securities using this prospectus. Such financial institution or third party may transfer its short position to investors in our securities or in connection with a simultaneous offering of other securities offered by this prospectus or otherwise.

The third parties in any of the sale transactions described above will be underwriters and will be identified in the applicable prospectus supplement or in a post-effective amendment to the registration statement of which this prospectus forms a part.

General Information

We may have agreements with the agents, dealers and underwriters to indemnify them against certain civil liabilities, including liabilities under the Securities Act of 1933, or to contribute with respect to payments that the agents, dealers or underwriters may be required to make. Agents, dealers and underwriters may also be our customers, may engage in material transactions with us, and may perform services for us in the ordinary course of their businesses.

The securities may or may not be listed on a national securities exchange. We cannot assure you that there will be a market for the securities. Unless otherwise specified in the prospectus supplement, each of the series of the securities will be a new issue with no established trading market.
