the right, on one or more occasions, to defer the payment of interest on the Fixed-to-Floating Rate Subordinated Notes as described in this prospectus supplement for
one or more consecutive interest periods for up to five years. Deferred interest will accrue additional interest at an annual rate equal to the annual interest rate then
applicable to the Fixed-to-Floating Rate Subordinated Notes.
The principal amount of the Fixed-to-Floating Rate Subordinated Notes will mature on March 27, 2048. Payment of the principal on the Fixed-to-Floating Rate
Subordinated Notes will be accelerated only in the case of a bankruptcy of or certain other insolvency events with respect to Assurant, Inc. There is no right of

Table of Contents
at any time or in part from time to time, at a redemption price equal to their principal amount plus accrued and unpaid interest (including compounded interest) to, but

amount of the Fixed-to-Floating Rate Subordinated Notes, excluding any Fixed-to-Floating Rate Subordinated Notes held by us or any of our affiliates, must remain

acquisition of TWG Holdings Limited (the "TWG Acquisition"), to refinance our 2018 Notes (as defined herein) and to pay related fees and expenses. See "Summary
--Recent Developments" and "Use of Proceeds." If the TWG Acquisition has not closed on or prior to December 17, 2018 or an Acquisition Termination Event (as

This summary contains selected information about us and this offering. Because this is a summary, it may not contain all the information that
may be important to you. You should read this entire prospectus supplement and the accompanying prospectus carefully, including, but not limited to,

The Company
Assurant is a global provider of risk management solutions in the housing and lifestyle markets, protecting where people live and the goods they
buy. Assurant operates in North America, Latin America, Europe and Asia Pacific through three operating segments: Global Housing, Global
Lifestyle, and Global Preneed. Assurant partners with clients who are leaders in their industries to provide consumers a diverse range of protection
products and services. Through its Global Housing segment, Assurant provides lender-placed homeowners, manufactured housing and flood
insurance; renters insurance and related products (referred to as our "multi-family housing" business); and valuation and field services (referred to as
our "mortgage solutions" business). Through its Global Lifestyle segment, Assurant provides mobile device protection products and related services
and extended service products and related services for consumer electronics and appliances (referred to as our "Connected Living" business); vehicle
protection services; and credit insurance. Global Preneed provides pre-funded funeral insurance and annuity products.
Our Competitive Strengths
Our financial strength and our core capabilities across our businesses create competitive advantages that we believe allow us to support our
clients and our profitable growth over the long term.
Our financial strength. We believe we have a strong balance sheet with a low leverage ratio. As of December 31, 2017, we had $31.84 billion
in assets and our debt to total capital was 20.0%. In addition, our Global Housing, Global Lifestyle and Global Preneed segments generate significant
amounts of cash flow, which provides us with the flexibility to make appropriate investments in strategic capabilities, and enter into partnerships with
our clients.
Client and consumer insights support product 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 consumers they serve. We intend to continue to capitalize on our client and consumer
insights to introduce new and innovative products and services and to adapt those products and services to 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 specific client needs and provide a more seamless experience for consumers. Offering end-to-end solutions allows us to adapt more quickly and
efficiently to client and consumer needs. Visibility across the value chain helps us collect and share insights to improve the consumer experience and
our offerings.

Our Strategy for Profitable Growth
Our vision is to be the premier provider of risk management solutions within the housing and lifestyle markets globally. To achieve this vision,
we recently underwent a multi-year transformation to position ourselves for long-term profitable growth by:
Growing our portfolio of market leading businesses. We leverage our competitive strengths to focus on niche businesses where we can
maintain or reach market leading positions and achieve attractive returns. We periodically assess our business portfolio to ensure we align resources
with the best opportunities within the housing and lifestyle markets and, currently, we have identified connected living, multi-family housing and
vehicle protection services as key businesses targeted for growth. We are focused on growing our businesses by continuing to invest in niche
capabilities, further expanding our offerings and diversifying our distribution channels.
Providing integrated risk management offerings. We provide an array of services that are complementary to our risk-based products. As we
adapt our business portfolio to respond to client and consumer needs, we expect that our mix of business will continue to evolve. We expect future
business mix shifts to further diversify our revenue and earnings. In 2017, fee-based, capital-light businesses accounted for approximately 50% of our
operating segments' net earned premiums, fees and other income.
Implementing a more agile and efficient operating model. We expect that the implementation of our global operating model, including a more
integrated organizational structure across our global operations, will achieve efficiencies to support our profitable growth long-term. We reorganized

424B5
our global business operating structure to increase competitive agility and deliver superior customer experience and centralized key support functions
to reduce overall expenditures over time and benefit from economies of scale.
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 prudent and disciplined approach to managing our capital. We target new business
and capabilities that complement or support our business model, which is focused on expanding capabilities and distribution in targeted growth
businesses globally.
Recent Developments
On January 9, 2018, we announced that we amended the structure of the TWG Acquisition. Under the revised terms, we will acquire TWG and
remain a Delaware corporation. We intend to fund the purchase price, the refinancing of $350 million aggregate principal amount of our 2.50% Senior
Notes due 2018 (the "2018 Notes") and related fees and expenses with the net proceeds of this offering, the net proceeds from the March 12, 2018
issuance of 2,875,000 shares of our Mandatory Convertible Preferred Stock, available cash on hand and common stock consideration. The acquisition
is expected to close in the second quarter of 2018, subject to the receipt of regulatory approvals and other customary closing conditions. This offering
is not conditioned upon the completion of the TWG Acquisition.

Rate Subordinated Notes will bear additional interest at the then-
applicable interest rate of the Fixed-to-Floating Rate Subordinated
Notes, compounded on each interest payment date, subject to

compounded interest thereon) on the Fixed-to-Floating Rate
Subordinated Notes, we can again defer interest payments on the
Fixed-to-Floating Rate Subordinated Notes as described above.
Certain Payment Restrictions Applicable to Us
At any time when we have given notice of our election to defer
interest payments on the Fixed-to-Floating Rate Subordinated Notes
but the related deferral period has not yet commenced or a deferral
period is continuing, we and our subsidiaries generally may not make
payments on or redeem or purchase any shares of our capital stock or
any of our debt securities or guarantees that rank upon our liquidation

Notes, subject to certain limited exceptions.

The terms of the Fixed-to-Floating Rate Subordinated Notes permit us
to make any payment of current or deferred interest on our pari passu
securities that is made pro rata to the amounts due on such parity
securities and the Fixed-to-Floating Rate Subordinated Notes.
