operations through subsidiaries, which generate a substantial portion of their respective core operating income and cash flow. As a result, distributions or advances from subsidiaries of Chubb INA and Chubb Limited are a major source of funds
necessary for Chubb INA and Chubb Limited to meet their respective debt service and other obligations. Contractual provisions, laws or regulations, as well as the subsidiaries&#146; financial condition and operating requirements, may limit the
ability of Chubb INA or Chubb Limited to obtain cash required to pay Chubb INA&#146;s debt service obligations, including payments on the Notes, or Chubb Limited&#146;s payment obligations under the guarantee. The Notes will be structurally
subordinated to all obligations of Chubb&nbsp;INA&#146;s subsidiaries, including claims with respect to trade payables. Chubb Limited&#146;s guarantee of the Notes will be structurally subordinated to all obligations of Chubb Limited&#146;s
subsidiaries, including claims with respect to trade payables. This means that holders of the Notes will have a junior position to the claims of creditors of Chubb INA&#146;s subsidiaries on their assets and earnings, and holders of the guarantee
will have a junior position to the claims of creditors of Chubb Limited&#146;s subsidiaries on their assets and earnings. At June&nbsp;30, 2020, Chubb INA and its subsidiaries had a total of approximately $15&nbsp;billion of indebtedness outstanding
(other than trade payables and repurchase agreements). At June&nbsp;30, 2020, Chubb Limited had approximately $15&nbsp;billion of indebtedness outstanding (other than trade payables and repurchase agreements) on a consolidated basis, all of which is
subsidiary indebtedness (at Chubb INA) and thus would be structurally senior to Chubb Limited&#146;s guarantee of the Notes. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman"><B><I>The

under our secured debt agreements will be entitled to exercise the remedies available to a secured lender. Accordingly, the secured lenders will have a prior claim on our assets to the extent of their liens, and it is possible that there will be
insufficient assets remaining from which claims of the holders of these Notes can be satisfied. As of the date of this prospectus supplement, we do not have significant amounts of secured indebtedness. </P>

independently of any other agency&#146;s rating. Actual or anticipated changes or downgrades in our credit ratings, including any announcement that our ratings are under further review for a downgrade, could affect the market value of the Notes and

Securities and Chubb Guarantee&#148; in the accompanying prospectus. In this section, &#147;Chubb INA&#148; refers to Chubb INA Holdings Inc., the issuer of the Notes, and &#147;Chubb&#148; refers to Chubb Limited, the guarantor of the Notes and, in
each case, not to any of their respective subsidiaries. </I></P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>General </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Notes will be issued as a separate series of debt securities under the indenture dated as of August&nbsp;1,&nbsp;1999 among Chubb INA, as
issuer, Chubb, as guarantor, and The Bank of New York Mellon Trust Company, N.A. (formerly known as The Bank of New York Trust Company, N.A., successor to J.P.&nbsp;Morgan Trust&nbsp;Company, National Association and The First National Bank of
Chicago), as trustee, as amended by the first supplemental indenture dated as of March&nbsp;13, 2013 between Chubb, Chubb INA and the trustee. This indenture constitutes the &#147;Chubb INA senior indenture&#148; described in the accompanying
prospectus. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The indenture does not limit the amount of notes, debentures or other evidences of indebtedness that Chubb INA may issue
thereunder and provides that notes, debentures or other evidences of indebtedness may be issued from time to time in one or more series. Chubb INA may from time to time, without giving notice to or seeking the consent of the holders of the Notes,
issue debt securities with the same terms as the Notes (except for the issue date and, in some cases, the public offering price and the amount and date of the first interest payment) and ranking equally and ratably with the Notes offered hereby. Any
additional debt securities having such similar terms, together with the Notes offered hereby, will constitute a single series of securities under the indenture, including for purposes of voting and redemptions; provided that such additional debt
securities are fungible with Notes for U.S. federal income tax purposes. No such additional debt securities may be issued if an &#147;event of default&#148; (as such term is defined in the accompanying prospectus) has occurred and is continuing with
respect to the Notes. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Notes will initially be limited to $1,000,000,000 in aggregate principal amount and will mature on September
15, 2030. The Notes will bear interest at the rate of 1.375% per year from the original issue date (September 17, 2020), or from the most recent interest payment date to which interest has been paid or provided for. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Chubb INA will make interest payments on the Notes semi-annually in arrears on March 15 and September&nbsp;15 of each year, beginning on March
15, 2021, to the holders of record at the close of business on the immediately preceding March 1 and September 1, respectively (whether or not a business day). Interest on the Notes will be computed on the basis of a
<FONT STYLE="white-space:nowrap">360-day</FONT> year consisting of twelve <FONT STYLE="white-space:nowrap">30-day</FONT> months. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">If any
interest payment date or maturity or redemption date falls on a day that is not a business day, the required payment shall be made on the next business day as if it were made on the date such payment was due and no interest shall accrue on the
amount so payable from and after such interest payment date or maturity or redemption date, as the case may be, to such next business day. &#147;Business day&#148; means any day other than a Saturday, Sunday or other day on which banking
institutions in The City of New York are authorized or obligated by law, regulation or executive order to close. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Chubb INA will issue the

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Notes will be senior unsecured obligations of Chubb INA and will rank equally in right of payment with all of Chubb INA&#146;s other
unsecured and unsubordinated indebtedness from time to time outstanding. The guarantee will be a senior unsecured obligation of Chubb and will rank equally in right of payment with all of Chubb&#146;s other unsecured and unsubordinated indebtedness
from time to time outstanding. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Notes will be effectively subordinated to any secured indebtedness of Chubb INA or Chubb, as the case
may be, to the extent of the value of the assets securing such indebtedness. The indenture does not limit the amount of debt that Chubb INA, Chubb or their respective subsidiaries can incur. However, the indenture does restrict the ability of Chubb
INA, Chubb and their respective subsidiaries to incur secured debt. See &#147;Description of Chubb INA Debt Securities and Chubb Guarantee&#151;Covenants Applicable to Chubb INA Senior Debt Securities&#148; in the accompanying prospectus. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In addition, both Chubb and Chubb INA conduct their operations through subsidiaries, which generate a substantial portion of their respective
core operating income and cash flow. As a result, distributions or advances from subsidiaries of Chubb INA and Chubb are a major source of funds necessary for Chubb INA and Chubb to meet their respective debt service and other obligations.
Contractual provisions, laws or regulations, as well as the subsidiaries&#146; financial condition and operating requirements, may limit the ability of Chubb INA or Chubb to obtain cash required to pay Chubb INA&#146;s debt service obligations,
including payments on the Notes, or Chubb&#146;s payment obligations under the guarantee. The Notes will be structurally subordinated to all obligations of Chubb&nbsp;INA&#146;s subsidiaries, including claims with respect to trade payables. The
guarantee will be structurally subordinated to all obligations of Chubb&#146;s subsidiaries, including claims with respect to trade payables. This means that holders of the Notes will have a junior position to the claims of creditors of Chubb
INA&#146;s subsidiaries on their assets and earnings, and holders of the guarantee will have a junior position to the claims of creditors of Chubb&#146;s subsidiaries on their assets and earnings. At June&nbsp;30, 2020, Chubb INA and its
subsidiaries had a total of approximately $15&nbsp;billion of indebtedness outstanding (other than trade payables and repurchase agreements). At June&nbsp;30, 2020, Chubb had approximately $15&nbsp;billion of indebtedness outstanding (other than
trade payables and repurchase agreements) on a consolidated basis, all of which is subsidiary indebtedness (at Chubb INA) and thus would be structurally senior to Chubb&#146;s guarantee of the Notes. </P>

or, in the event that payments are required to be made by Chubb pursuant to its obligations under the guarantee, Chubb will, subject to the exceptions and limitations set forth below, pay such additional amounts as are necessary in order that the

through participants, the ability of a person having an interest in Notes represented by a global note to pledge or transfer those interests to persons or entities that do not participate in DTC&#146;s system, or otherwise to take actions in respect

considered the owners or holders thereof under the indenture or under such Notes for any purpose, including with respect to the giving of any direction, instruction or approval to the trustee. Accordingly, each holder owning a beneficial interest in

discussion of certain United States federal tax consequences of the acquisition, ownership and disposition of the Notes by initial holders of Notes, but does not purport to be a complete analysis of all the potential tax considerations. This
discussion is based upon the Internal Revenue Code of 1986, as amended (the &#147;Code&#148;), the Treasury Regulations thereunder and administrative rulings and court decisions, all as of the date hereof, and all of which are subject to change,
possibly retroactively. Unless otherwise stated, this discussion is limited to the tax consequences to those persons who are original beneficial owners of the Notes (&#147;Holders&#148;) who purchase Notes at their original issue price (generally
the first price at which a substantial amount of the Notes are sold for money to the public, not including purchases by bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers)
for cash and who hold such Notes as capital assets, within the meaning of Section&nbsp;1221 of the Code, and assumes that such issue price is the price stated on the cover of this offering memorandum. This discussion does not consider any specific
facts or circumstances or special tax rules that may apply to a particular Holder based on its status (including, for example, a bank, a financial institution, an accrual method taxpayer that files applicable financial statements (as described in
section 451(b) of the Code), an insurance company, a passive foreign investment company, a controlled foreign corporation, an individual retirement or other <FONT STYLE="white-space:nowrap">tax-deferred</FONT> account, an S corporation, a
broker-dealer or dealer or trader in securities or currencies, a <FONT STYLE="white-space:nowrap">tax-exempt</FONT> organization, a partnership or other pass-through entity, an expatriate, a real estate investment trust, a regulated investment
company, a person that holds securities as part of a straddle, hedge, conversion transaction, or other integrated investment, a person who owns directly, indirectly or constructively, five percent (5%) or more of Chubb Limited&#146;s stock, persons
who are members of an &#147;expanded group&#148; with Chubb INA within the meaning of the Treasury regulations under Section&nbsp;385 of the Code, or a government or its controlled entities). This discussion also does not address the tax
consequences to U.S. Holders (as defined below) that have a functional currency other than the U.S. dollar. In addition, this discussion does not address U.S. federal alternative minimum tax, Medicare tax on unearned income or estate and gift tax
consequences or any aspect of state, local or foreign taxation. We have not sought any ruling from the Internal Revenue Service (the &#147;IRS&#148;) with respect to the statements made and the conclusions reached in this discussion, and we cannot
assure you that the IRS will agree with such statements and conclusions. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">For purposes of this discussion, a &#147;U.S. Holder&#148; means
a Holder that is, for U.S. federal income tax purposes, (1)&nbsp;a citizen or resident of the United States, (2)&nbsp;a corporation or other entity taxable as a corporation created or organized in the United States or under the laws of the United
States, any state thereof, or the District of Columbia, (3)&nbsp;an estate whose income is includible in gross income for United States federal income tax purposes regardless of its source, or (4)&nbsp;a trust whose administration is subject to the
primary supervision of a United States court and which has one or more United States persons (as defined under the Code) who have the authority to control all substantial decisions of the trust or if a valid election to be treated as a U.S. person
is in effect with respect to such trust. A <FONT STYLE="white-space:nowrap">Non-U.S.</FONT> Holder is a Holder that is neither a U.S. Holder nor a partnership or other entity or arrangement treated as a partnership for U.S. federal income tax
purposes. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">If a partnership or other entity or arrangement treated as a partnership for United States federal income tax purposes holds
the Notes, the tax treatment of a partner thereof will generally depend upon the status of the partner and the activities of the partnership. Partners in a partnership holding the Notes should consult their tax advisors as to the tax consequences to

Notes, U.S. Holders will be required to include in income any additional amounts described above in &#147;Description of the Notes and Guarantee&#151;Payments of Additional Amounts&#148; and any interest payments from Chubb Limited pursuant to the

<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><I>Disposition</I>&#151;In general, a U.S. Holder will recognize gain or loss upon the sale, exchange, redemption or other taxable disposition
of the Notes measured by the difference between (1)&nbsp;the amount realized (except to the extent attributable to accrued but unpaid interest, which is treated as interest as described above) and (2)&nbsp;the U.S. Holder&#146;s adjusted tax basis
in the Notes. A U.S. Holder&#146;s adjusted tax basis in the Notes generally will equal the cost of the Notes to the U.S. Holder reduced by any payments other than qualified stated interest made on such Note. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Any gain or loss recognized by a U.S. Holder upon the sale, exchange, redemption or other taxable disposition of the Notes will generally be
capital gain or loss and will be long-term capital gain or loss, provided the Notes had been held by such U.S. Holder for more than one year at the time of disposition. In the case of individual U.S. Holders, long-term capital gain is currently
subject to a maximum U.S. federal income tax rate of 20%. The deductibility of capital losses by U.S. Holders is subject to limitations. </P>

or to stabilize the prices of the Notes. The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the other 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. Any of these activities, as well as other purchases by the underwriters for their own accounts, may stabilize or maintain the market
prices of the Notes above independent market levels, but no representation is made hereby of the magnitude of any effect that the transactions described above may have on the market price of the Notes. The underwriters will not be required to engage

November&nbsp;3, 2022, which are expected to be repaid at maturity using the net proceeds from this offering plus available cash. Certain of the underwriters or their affiliates that have a lending relationship with us routinely hedge, and certain
other of the underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, such underwriters and their affiliates would hedge such exposure by entering into transactions
which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the Notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading
prices of the Notes offered hereby. The underwriters and their respective affiliates may also make investment recommendations or publish or express independent research views in respect of such securities or financial instruments and may at any time

distribution to be paid in four quarterly installments on dates determined by its Board of Directors. In recent years, Chubb has paid dividend distributions out of capital contribution reserves (additional paid in capital) in four quarterly
installments, and prior to that paid dividend distributions were made as a share capital decrease in the form of a par value reduction, in each case in four quarterly installments. Chubb currently intends, subject to the discretion of its Board of
Directors and the needs of its business, to propose at each annual general meeting a dividend distribution out of capital contribution reserves. At its 2018 annual general meeting, Chubb&#146;s shareholders approved an annual dividend of up to U.S.
$2.92 per share, to be paid in installments as determined by the Board of Directors (currently expected to be paid in U.S. $0.73 per share quarterly dividend installments). The first quarterly installment in the amount of U.S. $0.73 per share was

profits from previous business years, or if the reserves of the corporation are sufficient to allow distribution of a dividend. The board of directors of a Swiss corporation may propose that a dividend be paid, but cannot itself authorize the
dividend independently from a shareholders&#146; authorization of a maximum amount. The company auditors must confirm that the dividend proposal of the Board of Directors conforms with statutory law and the articles of association. Prior to the
distribution of dividends, five percent of the annual profits must be allocated to the general reserve until the amount of general reserves has reached twenty percent of the <FONT STYLE="white-space:nowrap">paid-in</FONT> nominal share capital.
Chubb&#146;s Articles of Association can provide for a higher general reserve or for the creation of further reserves setting forth their purpose and use. Once this level has been reached and maintained, the shareholders meeting may approve a
distribution of each year&#146;s profit within the framework of applicable legal requirements. Unless otherwise resolved, dividends are usually due and payable immediately after the shareholders&#146; resolution relating to the allocation of profits
has been passed. Under Swiss law, the statute of limitations in respect of claims for dividend payments is five years. Distributions in the form of a par value reduction must also be approved by shareholders, require confirmation by an audit expert

organizational regulations, a copy of which is incorporated by reference as an exhibit to the registration statement of which this prospectus forms a part. Further, holders of Chubb&#146;s signatory powers may in certain circumstances be unable to
validly exercise such powers by reason of a conflict of interest. The breach of these provisions entails personal liability of the directors and officers, to Chubb in particular. In addition, Swiss law contains provisions under which the members of
the Board of Directors and all persons engaged in the management may become liable to the company, to each shareholder and to the company&#146;s creditors for damages caused by an intentional or negligent violation of their duties. Furthermore,
Swiss company law contains a provision under which payments made and other benefits granted to a shareholder or a director or any persons associated with them, other than at arm&#146;s length, must be repaid to the company if the recipient thereof

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><I>Exchange Control</I> &#151; Under current Swiss exchange control regulations, there are no limitations on the amount of payments that may be

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><I>Insurance Regulatory Provisions Concerning Change or Acquisition of Control</I> &#151; Insurance regulatory authorities with jurisdiction
over Chubb&#146;s reinsurance and insurance subsidiaries may require prior approval of the acquisition or a change of control of the reinsurance or insurance subsidiary. In many cases, accumulating significantly less than a majority of Chubb&#146;s
shares may be deemed to be an acquisition or a change of control of one or more of Chubb&#146;s regulated reinsurance or insurance subsidiaries. The discussion below describes significant insurance regulatory provisions that may affect the
accumulation of Chubb&#146;s shares. </P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">For example, some of Chubb&#146;s subsidiaries are reinsurance and insurance companies domiciled or
commercially domiciled under the respective insurance codes of the states of Connecticut, Delaware, Georgia, Illinois, Indiana, Iowa, New Jersey, New York, Pennsylvania, Wisconsin and Texas in the United States. The insurance codes in these states
contain generally similar provisions to the effect that the acquisition or change of &#147;control&#148; of a domestic insurer or of any person that controls a domestic insurer cannot be consummated without the prior approval of the relevant
insurance regulator. In general, a presumption of &#147;control&#148; arises from the ownership, control, possession with the power to vote or possession of proxies regarding 10&nbsp;percent or more of the voting securities of a domestic insurer or
of a person that controls a domestic insurer. A person seeking to acquire control, directly or indirectly, of a domestic insurance company or of any person controlling a domestic insurance company must generally file with the relevant insurance
regulatory authority a statement relating to the acquisition of control containing certain information required by statute and published regulations and provide a copy of such statement to the domestic insurer. </P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In addition, many states&#146; insurance laws contain provisions that require <FONT STYLE="white-space:nowrap">pre-acquisition</FONT>
notification to state agencies of a change in control of a <FONT STYLE="white-space:nowrap">non-domestic</FONT> insurance company admitted in that state. While these <FONT STYLE="white-space:nowrap">pre-acquisition</FONT> notification statutes do
not authorize the state agency to disapprove the change of control, these statutes do authorize remedies, including the issuance of a cease and desist order with respect to the <FONT STYLE="white-space:nowrap">non-domestic</FONT> admitted insurer,
if, for example, undue market concentration exists. </P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Any future transactions involving the acquisition of 10&nbsp;percent or more of
Chubb&#146;s outstanding shares would generally require, and any future transactions involving disposition of 10&nbsp;percent or more of Chubb&#146;s outstanding shares may generally require, prior approval by the state insurance departments of the
states mentioned above or by certain regulators of other relevant jurisdictions. Similarly, they would generally require the <FONT STYLE="white-space:nowrap">pre-acquisition</FONT> notification in those jurisdictions that have adopted <FONT
STYLE="white-space:nowrap">pre-acquisition</FONT> notification provisions and may generally require the <FONT STYLE="white-space:nowrap">pre-disposition</FONT> notification in those jurisdictions that adopt
<FONT STYLE="white-space:nowrap">pre-disposition</FONT> notification provisions. These requirements may deter, delay or prevent transactions affecting the ownership of Chubb&#146;s shares by persons seeking to own more than 10&nbsp;percent of its
outstanding shares, or exceeding other relevant thresholds under applicable insurance regulations. See also &#147;UK&nbsp;Prudential Regulatory Authority and Lloyd&#146;s Related Requirements.&#148; </P>

that person, whether acting alone or in concert, holds 10&nbsp;percent or more of the shares or voting power in that entity or in its parent undertaking or it holds shares or voting power in that entity or its parent undertaking as a result of which
it is able to exercise significant influence over the management of the entity. Accordingly, any person who, whether acting alone or in concert, is a controller of Chubb may well also be a controller of a PRA authorized and, if applicable,
Lloyd&#146;s registered Chubb entity, which means any person considering owning 10&nbsp;percent of Chubb&#146;s shares or voting power must determine if PRA and, if applicable, Lloyd&#146;s advance approval is necessary. </P>

entity. Likewise, an existing controller should notify the PRA and, if applicable, Lloyd&#146;s if it increases its percentage of shares or voting power in the relevant entity from less than 20&nbsp;percent to 20&nbsp;percent or more, from less than
30&nbsp;percent to 30&nbsp;percent or more or from less than 50&nbsp;percent to 50&nbsp;percent or more, if it reduces its percentage of shares or voting power in the relevant entity from 50&nbsp;percent or more to less than 50&nbsp;percent, from
30&nbsp;percent or more to less than 30&nbsp;percent, or from 20&nbsp;percent or more to less than 20&nbsp;percent, or if it ceases to have control of that entity (i.e., it ceases to have 10&nbsp;percent or more of the shares or voting power in that

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The PRA has 60 working days to consider a person&#146;s application to acquire &#147;control.&#148; The PRA and, if applicable, Lloyd&#146;s
may object to a proposed acquisition or increase in control unless it is effectively satisfied that the applicant is a fit and proper person to have, or increase their, control, and the interests of consumers would not be threatened by that person

the amount of other indebtedness or Chubb INA debt securities, other than secured indebtedness which Chubb, Chubb INA or their respective subsidiaries may issue. </P>

securities, as described below under &#147;Subordination of Chubb INA Subordinated Debt Securities.&#148; The Chubb INA subordinated debt securities of any series issued to a Chubb Trust will rank equally with each other series of Chubb INA
subordinated debt securities issued to other Chubb Trusts. </P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Because Chubb INA is a holding company, its rights and the rights of its
