You must not rely on any unauthorized information or representations. This prospectus supplement and the accompanying prospectus constitute an offer to sell only the common shares offered hereby, but only under circumstances and in jurisdictions where it is lawful to do so.

Except where the context requires otherwise, references in this prospectus supplement to “Triton,” the “Company,” “us,” “we,” or “our” refer to Triton International Limited and its consolidated subsidiaries.

Securities may be offered or sold in Bermuda only in compliance with provisions of the Investment Business Act 2003, the Exchange Control Act of 1972, and related regulations of Bermuda, each as amended, that regulate the sale of securities in Bermuda. In addition, specific permission is required from the Bermuda Monetary Authority (the “BMA”), pursuant to the provisions of the Bermuda Exchange Control Act of 1972 and related regulations, each as amended, for all issuances and transfers of securities of Bermuda companies, other than in cases where the BMA has granted a general permission. The BMA, in its policy dated June 1, 2005, provides that where any equity securities of a Bermuda company, which would include our common shares, are listed on an appointed stock exchange (the NYSE is deemed to be an appointed stock exchange under Bermuda law), general permission is given for the issue and subsequent transfer of any securities of such company, from and/or to anon-resident of Bermuda, for as long as any equity securities of the company remain so listed. This prospectus supplement does not need to be filed with the Registrar of Companies in Bermuda in accordance with Part III of the Bermuda Companies Act 1981, as amended (the “Bermuda Companies Act”). Such provisions state that a prospectus in respect of the offer of shares in a Bermuda company whose equities are listed on an appointed stock exchange under Bermuda law does not need to be filed in Bermuda, so long as the company in question complies with the requirements of such appointed stock exchange in relation thereto.

PROSPECTUS SUPPLEMENT SUMMARY

This summary highlights certain information about our business and the offering. Because it is a summary, it does not contain all of the information that you should consider before investing in our common shares. You should read this entire prospectus supplement and the accompanying prospectus carefully, including the section entitled “Risk Factors,” and the documents incorporated by reference into this prospectus supplement and the accompanying prospectus before making an investment decision.

Our Company

We are the world’s largest lessor of intermodal containers. Intermodal containers are large, standardized steel boxes used to transport freight by ship, rail or truck. Because of the handling efficiencies they provide, intermodal containers are the primary means by which many goods and materials are shipped internationally. We also lease chassis which are used for the transportation of containers.

We operate our business in one industry, intermodal transportation equipment, and have two business segments, which also represent our reporting segments:

• Equipment leasing – our equipment leasing operations include the acquisition, leasing,re-leasing and ultimate sale of multiple types of intermodal transportation equipment, primarily intermodal containers.

• Equipment trading – we purchase containers from shipping line customers, and other sellers of containers, and resell these containers to container retailers and users of containers for storage orone-way shipment.

Our consolidated operations include the acquisition, leasing,re-leasing and subsequent sale of multiple types of intermodal containers and chassis. As of December 31, 2018, our total fleet consisted of 3.7 million containers and chassis, representing 6.2 million twenty-foot equivalent units (“TEU”) or 7.6 million cost equivalent units (“CEU”). We have an extensive global presence, offering leasing service through 23 offices located in 16 countries, and we provide access to our containers through a network of approximately 400 third-party container depot facilities located in approximately 45 countries as of December 31, 2018. Our primary customers include the world’s largest container shipping lines. For the year ended December 31, 2018, our twenty largest customers accounted for 85% of our lease billings, and our five largest customers accounted for 54% of our lease billings, and our two largest customers, CMA CGM S.A. and Mediterranean Shipping Company S.A., accounted for 20% and 14% of our lease billings, respectively.

We lease five types of equipment: (1) dry containers, which are used for general cargo such as manufactured component parts, consumer staples, electronics and apparel, (2) refrigerated containers, which are used for perishable items such as fresh and frozen foods, (3) special containers, which are used for heavy andover-sized cargo such as marble slabs, building products and machinery, (4) tank containers, which are used to transport bulk liquid products such as chemicals, and (5) chassis, which are used for the transportation of containers. Ourin-house equipment sales group manages the sale process for our used containers and chassis from our equipment leasing fleet and buys and sells new and used containers and chassis acquired from third parties.

Share Repurchase

Subject to the completion of this offering, we intend to repurchase from the underwriter 1,500,000 of the 7,132,790 common shares that are the subject of this offering. We refer to this transaction as the “share repurchase.”

To effect the share repurchase, we will pay a per share price to the underwriter equal to the price paid by the underwriter to purchase the shares from the selling shareholders in this offering. We intend to fund the share repurchase with cash on hand. Nothing in this prospectus supplement should be construed as an offer to sell, or the solicitation of an offer to buy, any of our common shares subject to the share repurchase.

TAX CONSIDERATIONS

Bermuda Tax Considerations

At the present time, there is no Bermuda income or profits tax, withholding tax, capital gains tax, capital transfer tax, estate duty or inheritance tax payable by us or by our shareholders in respect of our shares, other than shareholders, if any, that are ordinarily resident in Bermuda.

We have obtained from the Bermuda Minister of Finance under the Exempted Undertaking Tax Protection Act 1966, as amended, an assurance that, in the event that Bermuda enacts legislation imposing tax computed on profits, income, any capital asset, gain or appreciation, or any tax in the nature of estate duty or inheritance, then the imposition of any such tax shall not be applicable to us or to any of its operations or its shares, debentures or other obligations, until March 31, 2035. This assurance is subject to the proviso that it is not to be construed so as to prevent the application of any tax or duty to such persons as are ordinarily resident in Bermuda or to prevent the application of any tax payable in accordance with the provisions of the Land Tax Act 1967 or otherwise payable in relation to any property leased to us. Our Bermuda-domiciled subsidiaries each pay annual Bermuda government fees.

Material U.S. Federal Income Tax Considerations

The following is a discussion of U.S. federal income tax considerations applicable to the purchase, ownership and disposition of common shares by U.S. Holders (as defined below). This discussion deals only with our common shares held as capital assets by holders who purchase common shares in this offering. This discussion is based on the Internal Revenue Code, as amended (the “Code”), its legislative history, existing and proposed U.S. Treasury regulations promulgated thereunder, and published rulings and court decisions, all as in effect as of the date hereof, and all of which are subject to change, possibly with retroactive effect. This discussion does not cover all aspects of U.S. federal income taxation that may be relevant to the purchase, ownership or disposition of our common shares by prospective investors in light of their particular circumstances. In particular, this discussion does not address all of the tax considerations that may be relevant to certain types of investors subject to special treatment under U.S. federal income tax laws, such as the following:

• brokers or dealers in securities or currencies;

• financial institutions;

• pension plans;

• regulated investment companies;

• real estate investment trusts;

• cooperatives;

• tax-exempt entities;

• insurance companies;

• persons holding common shares as part of a hedging, integrated, conversion or constructive sale transaction or a straddle;

• traders in securities that elect to use amark-to-market method of accounting for their securities holdings;

• persons liable for alternative minimum tax;

• U.S. expatriates;

• accrual method taxpayers subject to special tax accounting rules as a result of their use of financial statements under Section 451(b) of the Code;

S-9

• partnerships or entities or arrangements treated as partnerships or other pass through entities for U.S. federal tax purposes (or investors therein); or

• U.S. Holders whose “functional currency” is not the U.S. dollar.

If a partnership, including for this purpose any entity that is treated as a partnership for U.S. federal income tax purposes, holds our common shares, the tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. A holder that is a partnership and the partners in such partnership should consult their tax advisors about the U.S. federal income tax consequences of the purchase, ownership and disposition of our common shares.

For purposes of this discussion, the term “U.S. Holder” means a beneficial owner of our common shares that is, for U.S. federal income tax purposes:

• an individual citizen or resident of the United States;

• a corporation, or entity treated as a corporation, organized in or under the laws of the United States or any state thereof or the District of Columbia;

• a trust if (a) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or (b) such trust has made a valid election to be treated as a U.S. person for U.S. federal income tax purposes; or

• an estate, the income of which is includible in gross income for U.S. federal income tax purposes, regardless of its source.

You will be considered a“Non-U.S. Holder” if you beneficially own our common shares and you are not a U.S. Holder and not a partnership or an entity or arrangement treated as a partnership for U.S. federal income tax purposes.

The discussion does not address anynon-income tax considerations, the potential application of the Medicare tax on net investment income, or any foreign, state or local tax consequences. Each holder of our common shares is urged to consult with such holder’s tax advisor with respect to the particular tax consequences to such holder.

IF YOU ARE CONSIDERING THE PURCHASE OF OUR COMMON SHARES, WE URGE YOU TO CONSULT YOUR TAX ADVISORS CONCERNING THE PARTICULAR U.S. FEDERAL INCOME TAX CONSEQUENCES TO YOU OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF OUR COMMON SHARES, AS WELL AS ANY CONSEQUENCES TO YOU ARISING UNDER STATE, LOCAL ANDNON-U.S. TAX LAWS.

Tax Consequences to U.S. Holders

Dividends

Dividends paid with respect to our common shares will generally be taxed as ordinary income to U.S. Holders to the extent that they are paid out of Triton’s current or accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent that the amount of any dividend exceeds our current and accumulated earnings and profits for a taxable year, the excess will first be treated as atax-free return of capital to the extent of the holder’s adjusted basis in the common share, causing a reduction in such adjusted basis in the same amount. The balance of the excess, if any, will be taxed as capital gain, which will be long-term capital gain if the common share has been held for more than one year at the time the dividend is received (as described below under “ —Sale, Exchange or Other Taxable Disposition”).

S-10

Subject to the PFIC rules discussed below, the gross amount of the dividends, if any, paid by Triton to individuals and othernon-corporate U.S. Holders, without reduction for any withholding taxes, may be eligible to be taxed at lower rates applicable to certain qualified dividends, provided that thenon-corporate U.S. Holder satisfies holding period requirements, and does not engage in hedging transactions, and provided that Triton is a qualified foreign corporation, and provided that Triton is not a PFIC for the taxable year in which we pay a dividend or the preceding taxable year. Dividends will be treated as foreign-source income for U.S. foreign tax credit purposes. Dividends with respect to our common shares will not be eligible for the dividends- received deduction generally allowed to U.S. corporations under the Code.

Sale, Exchange or Other Taxable Disposition

Subject to the PFIC rules discussed below, a U.S. Holder will generally recognize taxable gain or loss on the sale, exchange or other taxable disposition of a common share in an amount equal to the difference between the amount realized on the sale, exchange or other taxable disposition and the holder’s tax basis in the common share. Gain or loss, if any, will generally be U.S. source income for foreign tax credit limitation purposes.

Gain or loss realized on the sale, exchange or other taxable disposition of a common share generally will be capital gain or loss and will be long-term capital gain or loss if the common share has been held for more than one year.Non-corporate U.S. Holders may be eligible for preferential rates of U.S. taxation in respect of long-term capital gains. A U.S. Holder’s ability to deduct capital losses is subject to certain limitations.

PFIC Considerations

A PFIC is any foreign corporation if, after the application of certain “look-through” rules, (a) at least 75% of its gross income is “passive income” as that term is defined in the relevant provisions of the Code or (b) at least 50% of the average value of its assets produce “passive income” or are held for the production of “passive income.” In general, under the “look-through” rules, if a foreign corporation owns directly or indirectly at least 25% by value of the stock of another corporation, the foreign corporation is treated for purposes of the PFIC tests as owning its proportionate share of the assets of the other corporation and as receiving directly its proportionate share of the other corporation’s income. The determination as to PFIC status is made annually.

If a U.S. Holder is treated as owning PFIC stock, the holder will be subject to special rules generally intended to reduce or eliminate the benefit of the deferral of U.S. federal income tax that results from investing in a foreign corporation that does not distribute all of its earnings on a current basis. In such a case, under the PFIC rules, unless a U.S. Holder is permitted to and does elect otherwise under the Code, such U.S. Holder will be subject to special tax rules with respect to “excess distributions” and any gain from the disposition of our common shares. In particular, an “excess distribution” or such gain will be treated as if it had been recognized ratably over the holder’s holding period for the common shares, and amounts allocated to prior years starting with the first taxable year of Triton during which Triton was a PFIC will be subject to U.S. federal income tax at the highest prevailing tax rates on ordinary income for that year plus an interest charge.

Based on our current and expected income, valuation of our assets and our election to treat certain of our subsidiaries as disregarded entities for U.S. federal income tax purposes, we do not presently expect to be a PFIC for the current taxable year or the foreseeable future. However, because the PFIC determination is made by taking into account all of the relevant facts and circumstances regarding our business without the benefit of clearly defined bright line rules, it is possible we may be a PFIC for any taxable year or that the IRS may challenge our determination concerning our PFIC status.

In the case Triton is subsequently determined to be a PFIC, a U.S. Holder may also be able to avoid certain of the rules described above by making amark-to-market election and, in certain circumstances, a retroactive such election, provided that our common shares are treated as regularly traded on a qualified exchange or other market within the meaning of applicable U.S. Treasury Regulations. Our common shares are listed and regularly

S-11

traded on the NYSE, which is a qualified exchange or other market for these purposes. Consequently, assuming that our common shares continue to be regularly traded, we expect that themark-to-market election will be available to U.S. Holders if Triton is determined to be a PFIC, but no assurances can be given in this regard. If you make a validmark-to-market election for your common shares, you would include in income each year an amount equal to the excess, if any, of the fair market value of the common shares as of the close of your taxable year over your adjusted basis in such common shares. You would be allowed a deduction for the excess, if any, of the adjusted basis of your common shares over their fair market value as of the close of the taxable year, but only to the extent of any netmark-to-market gains on your common shares included in your income for prior taxable years. Amounts included in your income under amark-to-market election, as well as gain on the actual sale or other disposition of the common shares, would be treated as ordinary income. Ordinary loss treatment would also apply to the deductible portion of anymark-to-market loss on the common shares, as well as to any loss realized on the actual sale or disposition of the common shares, to the extent that the amount of such loss does not exceed the netmark-to-market gains previously included for such common shares. Your basis in the common shares would be adjusted to reflect any such income or loss amounts. If you make such amark-to-market election, tax rules that apply to distributions by corporations which are not PFICs would apply to distributions by us (except that the lower qualified dividends rate would not apply).

Alternatively, a U.S. Holder may avoid the PFIC tax consequences described above in respect of its common shares by making a timely “qualified electing fund” (“QEF”) election. To comply with the requirements of a QEF election, a U.S. Holder must receive certain information from us. Because we do not intend to provide such information, however, such election will not be available to you with respect of the common shares.

The adverse rules described above will continue to apply to any taxable year in which Triton is a PFIC and for which the U.S. Holder has neither a valid QEF election nor a validmark-to-market election in effect.

U.S. Holders are urged to consult with their tax advisors regarding the potential availability and consequences of amark-to-market election in case Triton is determined to be a PFIC in any taxable year.

UNDERWRITING

Morgan Stanley & Co. LLC is acting as underwriter of the offering. Subject to the terms and conditions set forth in an underwriting agreement among us, the selling shareholders and the underwriter, the selling shareholders, severally and not jointly, have agreed to sell to the underwriter, and the underwriter has agreed to purchase from the selling shareholders, the number of common shares set forth opposite its name below.

Underwriter	Number of Shares
Morgan Stanley & Co. LLC		7,132,790

Subject to the terms and conditions set forth in the underwriting agreement, the underwriter has agreed to purchase all of the common shares sold under the underwriting agreement if any of these common shares are purchased.

We and the selling shareholders, severally and not jointly, have agreed to indemnify the underwriter against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the underwriter may be required to make in respect of those liabilities.

Subject to the completion of the offering, we intend to repurchase from the underwriter 1,500,000 of the 7,132,790 common shares that are the subject of this offering at a price per share equal to the price at which the underwriter will purchase such shares from the selling shareholders in this offering.

The underwriter is offering the common shares, 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 common shares, and satisfaction of other conditions contained in the underwriting agreement, such as the receipt by the underwriter of officer’s certificates and legal opinions. The underwriter reserves the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

Commissions and Discounts

The underwriter has advised us that it proposes initially to offer the common shares to the public at the public offering price set forth on the cover page of this prospectus supplement and to dealers at that price less a concession not in excess of $0.10 per share. After the initial offering, the public offering price, concession or any other term of this offering may be changed.

The following table shows the underwriting discount to the underwriter for the common shares not subject to the share repurchase.

	Underwriting Discount(1)
Per common share	$	0.25
Total	$	1,408,197.50

(1) The common shares we repurchase from the underwriter will be purchased at a price per share equal to the price per share to be paid by the underwriter to the selling shareholders.

The expenses of this offering, not including the underwriting discount, that are payable by us are estimated to be approximately $300,000.

No Sales of Similar Securities

We, our executive officers and directors and certain significant shareholders have agreed not to sell or transfer any common shares or securities convertible into, exchangeable for, exercisable for, or repayable with

S-13

common shares, for 30 days after the date of this prospectus supplement without first obtaining the written consent of the underwriter. Specifically, we and these other persons have agreed, with certain limited exceptions, not to directly or indirectly:

• offer, pledge, sell or contract to sell any common shares,

• sell any option or contract to purchase any common shares,

• purchase any option or contract to sell any common shares,

• grant any option, right or warrant for the sale of any common shares,

• lend or otherwise dispose of or transfer any common shares,

• file or, in the case of thenon-Companylock-up signatories, request that we file a registration statement related to the common shares, or

• enter into any swap or other agreement that transfers, in whole or in part, the economic consequence of ownership of any common shares whether any such swap or transaction is to be settled by delivery of common shares or other securities, in cash or otherwise.

Thislock-up provision applies to common shares and to securities convertible into or exchangeable or exercisable for or repayable with common shares. It also applies to common shares owned now or acquired later by the person executing the agreement or for which the person executing the agreement later acquires the power of disposition.

NYSE Listing

The common shares are listed on the NYSE under the symbol “TRTN.”

Price Stabilization, Short Positions

Until the distribution of the common shares is completed, SEC rules may limit the underwriter and selling group members from bidding for and purchasing our common shares. However, the underwriter may engage in transactions that have the effect of stabilizing the price of the common shares, such as purchases and other activities that peg, fix or maintain that price.

In connection with this offering, the underwriter may bid for or purchase and sell shares of our common shares in the open market. These transactions may include short sales and purchases on the open market to cover positions created by short sales. Short sales involve the sale by the underwriter of a greater number of our common shares than they are required to purchase in this offering. The underwriter may close out any covered short position by purchasing common shares in the open market. A short position is more likely to be created if the underwriter is concerned that there may be downward pressure on the price of our common shares in the open market after pricing that could adversely affect investors who purchase in this offering.

Similar to other purchase transactions, the underwriter’s purchases to cover short sales and other activities may have the effect of raising or maintaining the market price of our common shares or preventing or retarding a decline in the market price of our common shares. As a result, the price of our common shares may be higher than the price that might otherwise exist in the open market. The underwriter may conduct these transactions on the NYSE, in theover-the-counter market or otherwise.

Neither we nor the underwriter 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 our common shares. In addition, neither we nor the underwriter makes any representation that the underwriter will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

S-14

Electronic Distribution

In connection with this offering, the underwriter or securities dealers may distribute prospectuses by electronic means, such ase-mail.

Other Relationships

The underwriter and its affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us or our affiliates. They have received, or may in the future receive, customary fees and commissions for these transactions.

In addition, in the ordinary course of their business activities, the underwriter and its affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. The underwriter and its affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

European Economic Area

None of this prospectus supplement, the accompanying prospectus or any related free writing prospectus is a prospectus for the purposes of the Prospectus Directive (as defined below). This prospectus supplement, the accompanying prospectus and any related free writing prospectus have been prepared on the basis that any offer of common shares in any Member State of the European Economic Area which has implemented the Prospectus Directive (each, a “Relevant Member State”) will be made pursuant to an exemption under the Prospectus Directive from the requirement to publish a prospectus for offers of common shares. Accordingly any person making or intending to make an offer in that Relevant Member State of common shares which are the subject of the offering contemplated in this prospectus supplement, the accompanying prospectus and any related free writing prospectus may only do so in circumstances in which no obligation arises for Triton International Limited or the underwriter to publish a prospectus pursuant to Article 3 of the Prospectus Directive in relation to such offer. Neither Triton International Limited nor the underwriter has authorized, nor do they authorize, the making of any offer of common shares in circumstances in which an obligation arises for Triton International Limited or the underwriter to publish a prospectus for such offer. The expression “Prospectus Directive” means Directive 2003/71/EC (as amended or superseded), and includes any relevant implementing measure in the Relevant Member State.

In relation to each Relevant Member State, with effect from and including the date on which the Prospectus Directive is implemented in that Relevant Member State, no offer of common shares which are the subject of the offering contemplated by this prospectus supplement, the accompanying prospectus and any related free writing prospectus to the public may be made in that Relevant Member State other than:

(a) to any legal entity which is a qualified investor as defined in the Prospectus Directive;

(b) to fewer than 150 natural or legal persons (other than qualified investors as defined in the Prospectus Directive), subject to obtaining the prior consent of the relevant underwriter nominated by Triton International Limited for any such offer; or

(c) in any other circumstances falling within Article 3(2) of the Prospectus Directive,

provided that no such offer of common shares shall require Triton International Limited or any underwriter to publish a prospectus pursuant to Article 3 of the Prospectus Directive.

S-15

For the purposes of this provision, the expression an “offer of common shares to the public” in relation to any common shares in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the common shares to be offered so as to enable an investor to decide to purchase or subscribe for the common shares, as the same may be varied in that Relevant Member State by any measure implementing the Prospectus Directive in that Relevant Member State.

ABOUT THIS PROSPECTUS

This prospectus is part of an “automatic shelf” registration statement that we filed with the Securities and Exchange Commission (the “SEC”) as a “well-known seasoned issuer” as defined in Rule 405 under the Securities Act of 1933, as amended (the “Securities Act”), using a “shelf” registration process. Under this process, we may sell from time to time any combination of the securities described in this prospectus. This prospectus only provides you with a general description of the securities that we may offer. Each time we or the selling securityholders sell securities, we will provide a supplement to this prospectus that contains specific information about the terms of that offering, including the specific amounts, prices and terms of the securities offered. The prospectus supplement may also add, update or change information contained in this prospectus. You should carefully read both this prospectus, any accompanying prospectus supplement and any free writing prospectus prepared by or on behalf of us, together with the additional information described under the heading “Where You Can Find More Information.”

We have not authorized anyone to provide you with any information other than that contained in or incorporated by reference into this prospectus, any accompanying prospectus supplement and any free writing prospectus prepared by or on behalf of us. We take no responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you. We are not making offers to sell the securities in any jurisdiction in which an offer or solicitation is not authorized or in which the person making such offer or solicitation is not qualified to do so or to anyone to whom it is unlawful to make an offer or solicitation.

The information in this prospectus is accurate as of the date on the front cover. You should not assume that the information contained in this prospectus is accurate as of any other date.

When used in this prospectus, the terms “Triton,” the “Company,” “we,” “our” and “us” refer to Triton International Limited and its consolidated subsidiaries, unless otherwise specified or the context otherwise requires.

Securities may be offered or sold in Bermuda only in compliance with provisions of the Investment Business Act 2003, the Exchange Control Act of 1972, and related regulations of Bermuda, each as amended, that regulate the sale of securities in Bermuda. In addition, specific permission is required from the Bermuda Monetary Authority (“BMA”), pursuant to the provisions of the Bermuda Exchange Control Act of 1972 and related regulations, each as amended, for all issuances and transfers of securities of Bermuda companies, other than in cases where the BMA has granted a general permission. The BMA, in its policy dated June 1, 2005, provides that where any equity securities of a Bermuda company, which would include our common shares, are listed on an appointed stock exchange (the NYSE is deemed to be an appointed stock exchange under Bermuda law), general permission is given for the issue and subsequent transfer of any securities of such company, from and/or to anon-resident of Bermuda, for as long as any equity securities of the company remain so listed. This prospectus does not need to be filed with the Registrar of Companies in Bermuda in accordance with Part III of the Bermuda Companies Act 1981, as amended (the “Bermuda Companies Act”). Such provisions state that a prospectus in respect of the offer of shares in a Bermuda company whose equities are listed on an appointed stock exchange under Bermuda law does not need to be filed in Bermuda, so long as the company in question complies with the requirements of such appointed stock exchange in relation thereto.

statements made in this prospectus, any accompanying prospectus supplement and the documents incorporated by reference herein and therein are qualified in their entirety by these cautionary statements, and there can be no assurance that the actual results or developments anticipated by us will be realized or, even if substantially realized, that they will have the expected consequences to, or effects on, Triton or its respective businesses or operations. Except to the extent required by applicable law, we undertake no obligation to update publicly or revise any forward-looking statement, whether as a result of new information, future developments or otherwise.

THE COMPANY

Triton is the world’s largest lessor of intermodal containers. Intermodal containers are large, standardized steel boxes used to transport freight by ship, rail or truck. Intermodal containers are the primary means by which many goods and materials are shipped internationally. Our management team consists of professionals responsible for managing the operations of our global fleet of containers, including the specification, order, acquisition, leasing, maintenance, repair,re-leasing and ultimate sale of multiple types of containers. Our business is also supported by a worldwide network of independent container depots and several active independent agents.

On July 12, 2016, Triton Container International Limited, an exempted company incorporated with limited liability under the laws of Bermuda (“TCIL”), and TAL International Group, Inc., a Delaware corporation (“TAL”), combined in anall-stock merger (the “Merger”). Under the terms of the transaction agreement related to the Merger, TCIL and TAL combined under a newly formed company, Triton International Limited, which is domiciled in Bermuda and is listed on the New York Stock Exchange under the stock symbol “TRTN.”

We operate our business in one industry, intermodal transportation equipment, and have two business segments:

• Equipment leasing — we own, lease and ultimately dispose of containers and chassis from our lease fleet, as well as manage containers owned by third parties.

• Equipment trading — we purchase containers from shipping line customers, and other sellers of containers, and resell these containers to container retailers and users of containers for storage orone-way shipment.

Our principal executive office is located at 22 Victoria Street, Hamilton HM12, Bermuda and our telephone number is (441)295-2287. We maintain a website at http://www.trtn.com. The information on our website is not incorporated by reference in this prospectus or any accompanying prospectus supplement, and you should not consider it a part of this prospectus or any accompanying prospectus supplement.

RISK FACTORS

Investing in our securities involves risk. See the risk factors described in our most recent Annual Report on Form10-K (together with any material changes thereto contained in subsequently filed Quarterly Reports on Form10-Q) and those contained in our other filings with the SEC that are incorporated by reference in this prospectus and any accompanying prospectus supplement. Before making an investment decision, you should carefully consider these risks as well as other information we include or incorporate by reference in this prospectus and any accompanying prospectus supplement. These risks could materially affect our business, financial condition or results of operations and cause the value of our securities to decline. You could lose all or part of your investment.

USE OF PROCEEDS

Except as otherwise set forth in any accompanying prospectus supplement, we expect to use the net proceeds from the sale of securities for general corporate purposes, including the purchase of containers.

Unless set forth in an accompanying prospectus supplement, we will not receive any proceeds in the event that securities are sold by a selling securityholder.

RATIO OF EARNINGS TO FIXED CHARGES AND RATIO OF EARNINGS TO

COMBINED FIXED CHARGES AND PREFERRED DIVIDENDS

The ratio of earnings to fixed charges and the ratio of earnings to combined fixed charges and preferred dividends for each of the periods indicated is set forth below. For purposes of computing these ratios, earnings represents income from continuing operations before income taxes and fixed charges. Fixed charges are the sum of (i) interest expensed and capitalized, (ii) amortized premiums, discounts and capitalized expenses related to indebtedness, and (iii) the portion of rents representative of interest. TCIL has been treated as the acquirer in the Merger for accounting purposes, and therefore, the ratio of earnings to fixed charges and the ratio of earnings to combined fixed charges and preferred dividends for Triton, included herein, for the periods prior to the date of the Merger on July 12, 2016 are for TCIL alone.

	Six Months Ended June 30,		Year Ended December 31,
	2017		2016			2015		2014		2013		2012
Ratio of Earnings to Fixed Charges(1)		1.7		—	(2)		1.8		2.1		2.5		3.3

(1) Our ratio of earnings to combined fixed charges and preferred dividends for the periods above are the same as our ratio of earnings to fixed charges because we had no preference shares outstanding for the periods presented and currently have no preference shares outstanding.

(2) Earnings were insufficient to cover fixed charges for such period and we are unable to disclose a ratio of earnings to fixed charges for such period. The dollar amount of the deficiency in earnings available for fixed charges for the year ended December 31, 2016 was approximately $13.6 million.

DESCRIPTION OF SECURITIES

This prospectus contains summary descriptions of the common shares, preference shares, depositary shares, debt securities, warrants, subscription rights, purchase contracts and purchase units that may be offered and sold from time to time. These summary descriptions are not meant to be complete descriptions of each security. However, at the time of an offering and sale, this prospectus together with the accompanying prospectus supplement will contain the material terms of the securities being offered.

DESCRIPTION OF SHARE CAPITAL

General

The following summary description of our share capital is based on the applicable provisions of the Bermuda Companies Act, our memorandum of association, as amended, and our amended and restatedbye-laws. This description does not purport to be complete and is qualified in its entirety by reference to the full text of the Bermuda Companies Act, as it may be amended from time to time, and to the terms of our memorandum of association andbye-laws, as each may be amended from time to time, which are incorporated by reference as exhibits to the registration statement of which this prospectus is a part. See “Where You Can Find More Information.” As used in this “Description of Share Capital,” the terms “Triton,” the “Company,” “we,” “our” and “us” refer to Triton International Limited, a Bermuda exempted company, and do not, unless otherwise specified, include our subsidiaries.

Common Shares

We are authorized to issue up to 294,000,000 common shares, par value $0.01 per share.

8

As of September 1, 2017, 74,536,402 common shares were outstanding and held by approximately 72 holders of record.

Liquidation and Preemptive Rights

In the event of a voluntary or involuntary liquidation, dissolution or winding up of Triton, the holders of Triton common shares will be entitled to share equally in any of the assets available for distribution after Triton has paid in full all of its debts and after the holders of all series of Triton’s outstanding preferred shares, if any, have received their liquidation preferences in full.

Holders of Triton common shares will not be entitled to preemptive rights. Shares of Triton common shares will not be convertible into shares of any other class of common shares.

Dividend Rights

Under Bermuda law, shareholders of Triton will be entitled to receive dividends when and as declared by the board of directors of the Company (the “Triton Board”) out of any funds of the company legally available for the payment of such dividends, subject to any preferred dividend rights that may exist from time to time. Bermuda law does not permit payment of dividends, or distributions of contributed surplus, by a company if there are reasonable grounds for believing that:

• the company is, or would be, after the payment is made, unable to pay its liabilities as they become due; or

• the realizable value of the company’s assets would be less than its liabilities.

Under Triton’sbye-laws, the Triton Board has the power to declare dividends or distributions out of contributed surplus, and to determine that any dividend shall be paid in cash or shall be satisfied in paying up in full shares to be issued to the shareholders credited as fully paid or partly paid or partly in one way or partly in the other. The Triton Board may also pay any fixed cash dividend whenever the position of the company justifies such payment.

Voting Rights

Subject to the rights, if any, of the holders of any series of preferred shares, if and when issued and subject to applicable law, each holder of Triton common shares will be entitled to one vote per share and all voting rights will be vested in those holders of record on the applicable record date on all matters voted on by the Triton shareholders. Holders of Triton common shares will have noncumulative voting rights, which means that the holders of more than 50% of the shares voting for the election of directors to the Triton Board can elect 100% of the directors to the Triton Board and the holders of the remaining shares will not be able to elect any directors to the Triton Board.

Meetings of Shareholders

Special general meetings of the shareholders of Triton may be called (i) by the Triton Board or (ii) when requisitioned by shareholders pursuant to the provisions of the Bermuda Companies Act. Under the Bermuda Companies Act, the shareholders may requisition a special general meeting, provided they hold at the date of the deposit of the requisition shares representing not less than 10% of thepaid-up capital of the company. The requisition must state the purpose of the meeting, and must be signed by the requisitionists and deposited at the registered office of the company. If, within 21 days from the date of the deposit of the requisition, the directors do not proceed to convene a meeting, the requisitionists, or any of them representing more than 50% of the total voting rights of all of them, may themselves convene a meeting, which must be convened within three months of the date of the deposit of the requisition.

Restrictions on Transfers of Shares

The Triton Board may in its absolute discretion, and without providing a reason, refuse to register the transfer of a share which is not fully paid up. The Triton Board may also refuse to register a transfer unless the shares of Triton are (i) listed on an appointed stock exchange (of which the NYSE is one) or (ii) (A) a duly executed instrument of transfer is provided to Triton or Triton’s transfer agent accompanied by the certificate (if any has been issued) in respect of the shares to which it relates and by such other evidence as the Triton Board may reasonably require to show the right of the transferor to make the transfer, (B) the instrument of transfer is only in respect of one class of shares, (C) the instrument of transfer is in favor of less than five persons jointly, and (D) all applicable consents, authorizations, permissions or approvals of any governmental body or agency in Bermuda or any other applicable jurisdiction have been obtained (if required). If the Triton Board refuses to register a transfer of any share, it must send to the transferee notice of the refusal within three months after the date on which the instrument of transfer was lodged with Triton.

Shares listed on an appointed stock exchange, such as the NYSE, may be transferred by any means permitted by the rules of such exchange.

Election and Removal of Directors

Except in the case of vacancies, each director is elected by the affirmative vote of a majority of the votes cast at the general meeting of shareholders of Triton.

Thebye-laws of Triton provide that any vacancies on the Triton Board not filled at any general meeting will be deemed casual vacancies and the Triton Board, so long as a quorum of directors remains in office, will have the power at any time and from time to time, to appoint any individual to be a director so as to fill a casual vacancy. A director so appointed will hold office only until the next following annual general meeting (“AGM”). If not reappointed at such AGM, the director will vacate office at the conclusion of the AGM.

Under the Bermuda Companies Act, a director may be removed from office by the shareholders at a special general meeting called for that purpose. The notice of a meeting convened for the purpose of removing a director must contain a statement of intention to do so and be served on such director not less than 14 days before the meeting. The director subject to removal will be entitled to be heard on the motion for his removal.

Amendment of Memorandum of Association

Under the Bermuda Companies Act, the memorandum of association of a company may be amended by the affirmative vote of a majority resolution of the Triton Board, but the amendment will not be operative unless and until it is approved at a subsequent general meeting of the shareholders by a resolution approved by the affirmative vote of a majority of the votes cast on such resolution. An amendment to the memorandum of association that alters a company’s business objects may require approval by the Bermuda Minister of Finance, who may grant or withhold approval at his or her discretion.

Amendment ofBye-laws

Subject to certain exceptions, the Tritonbye-laws may be revoked or amended by the affirmative vote of a majority resolution of the Triton Board, but the revocation or amendment will not be operative unless and until it is approved at a subsequent general meeting of the shareholders of Triton by a resolution approved by the affirmative vote of a majority of the votes cast on such resolution.

Approval of Certain Transactions

Amalgamations and Mergers: Under the Bermuda Companies Act, the amalgamation or merger of a Bermuda company with another company (wherever incorporated) (other than certain affiliated companies)

10

requires the amalgamation or merger to be approved by the Triton Board and by its shareholders. The Tritonbye-laws provide that a merger or amalgamation must be approved by (i) the affirmative vote of a majority of the Triton Board and (ii) the affirmative vote of a majority of votes cast at a general meeting of shareholders. For purposes of approval of an amalgamation or merger, all shares, whether or not otherwise entitled to vote, carry the right to vote. Holders of a separate class of shares are entitled to a separate class vote if the rights of such class would be varied by virtue of the amalgamation or merger.

Sale of Assets: The Bermuda Companies Act is silent on whether a company’s shareholders are required to approve a sale, lease or exchange of all or substantially all of a company’s property and assets. Bermuda law does require, however, that shareholders approve certain forms of mergers and reconstructions.

Takeovers: Bermuda does not have any takeover regulations applicable to shareholders of Bermuda companies.

Listing

Our common shares are listed on the NYSE under the symbol “TRTN.”

Transfer Agent and Registrar

The transfer agent and registrar for our common shares is Computershare Trust Company, N.A.

Preference Shares

This section describes the general terms and provisions of preference shares that we are authorized to issue. An accompanying prospectus supplement will describe the specific terms of the preference shares offered through that prospectus supplement, as well as any general terms described in this section that will not apply to those preference shares. If there are differences between the prospectus supplement relating to a particular series of preference shares and this prospectus, the prospectus supplement will control. The terms of a new series of preference shares will be recorded in a resolution of the Triton Board, which will be annexed as an appendix to the Company’s amended and restatedbye-laws. Such resolutions will establish the number of shares included in a designated series and fix the designation, powers, privileges, preferences and rights of the shares of each series as well as any applicable qualifications, limitations or restrictions. You should refer to the applicable resolutions as well as our memorandum of association before deciding to buy our preference shares as described in any accompanying prospectus supplement.

The Triton Board has been authorized to provide for the issuance of up to 6,000,000 shares of our preference shares in multiple series without the approval of shareholders. With respect to each series of our preference shares, the Triton Board has the authority to fix the following terms:

• the designation of the series, which may be by distinguishing number, letter or title;

• the number of shares within the series;

• whether dividends are cumulative and, if cumulative, the dates from which dividends are cumulative;

• the rate of any dividends, any conditions upon which dividends are payable, and the dates of payment of dividends;

• whether the shares are redeemable, the redemption price and the terms of redemption;

• the amount payable for each share if we dissolve or liquidate;

• whether the shares are convertible or exchangeable, the price or rate of conversion or exchange, and the applicable terms and conditions;

11

• any restrictions on issuance of shares in the same series or any other series;

• voting rights applicable to the series of preference shares; and

• any other rights, priorities, preferences, restrictions or limitations of such series.

The right of a holder of preference shares to receive payment in respect thereof upon any liquidation, dissolution or winding up of us will be subordinate to the rights of our general creditors.

Anti-Takeover Effects of Provisions of the Memorandum of Association,Bye-laws and Other Agreements

Our shareholders might have more difficulty protecting their interests than would shareholders of a corporation incorporated in a jurisdiction of the United States. As a Bermuda company, Triton is governed by the Bermuda Companies Act. The Bermuda Companies Act differs in some material respects from laws generally applicable to United States corporations and shareholders, including the provisions relating to interested directors, mergers, amalgamations and acquisitions, takeovers, shareholder lawsuits and indemnification of directors.

Certain provisions under the shareholder agreements (the “Sponsor Shareholders Agreements”) with certain affiliates of Warburg Pincus LLC, certain affiliates of Vestar Capital Partners, Inc. and Bharti Global Limited (collectively, the “Sponsor Shareholders”), Triton’s memorandum of association and amended and restatedbye-laws and Bermuda law could discourage, delay or prevent a transaction involving a change in control of Triton, even if doing so would benefit Triton’s shareholders. These provisions include customary anti-takeover provisions and certain rights of our Sponsor Shareholders with respect to the designation of directors for nomination and election to the Triton Board, including the ability to appoint members to each board committee.

Anti-takeover provisions could substantially impede the ability of Triton’s public shareholders to benefit from a change in control or change of Triton’s management and the Triton Board and, as a result, may materially adversely affect the market price of Triton common shares and your ability to realize any potential change of control premium. These provisions could also discourage proxy contests and make it more difficult for you and other shareholders to elect directors of your choosing and to cause Triton to take other corporate actions you desire.

DESCRIPTION OF DEPOSITARY SHARES

We may offer depositary receipts representing fractional preference shares, rather than full preference shares. The preference shares represented by depositary shares will be deposited under a depositary agreement between us and a bank or trust company that meets certain requirements and is selected by us (the “Bank Depositary”). Each owner of a depositary share will be entitled to all the rights and preferences of the preference shares represented by the depositary share. As used in this “Description of Depositary Shares,” the terms the “Company,” “we,” “our” and “us” refer to Triton International Limited, a Bermuda exempted company, and do not, unless otherwise specified, include our subsidiaries.

The description in an accompanying prospectus supplement of any depositary shares we offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable depositary agreement, which will be filed with the SEC if we offer depositary shares. For more information on how you can obtain copies of any depositary agreement if we offer depositary shares, see “Where You Can Find More Information.” We urge you to read the applicable depositary agreement and any accompanying prospectus supplement in their entirety.

Dividends and Other Distributions

If we pay a cash distribution or dividend on a series of preference shares represented by depositary shares, the Bank Depositary will distribute such dividends to the record holders of such depositary shares. If the

12

distributions are in property other than cash, the Bank Depositary will distribute the property to the record holders of the depositary shares. However, if the Bank Depositary determines that it is not feasible to make the distribution of property, the Bank Depositary may, with our approval, sell such property and distribute the net proceeds from such sale to the record holders of the depositary shares.

Redemption of Depositary Shares

If we redeem a series of preference shares represented by depositary shares, the Bank Depositary will redeem the depositary shares from the proceeds received by the Bank Depositary in connection with the redemption. The redemption price per depositary share will equal the applicable fraction of the redemption price per share payable in respect of the preference shares so redeemed. If fewer than all the depositary shares are redeemed, the depositary shares to be redeemed will be selected by lot or pro rata as the Bank Depositary may determine.

Voting the Preference Shares

Upon receipt of notice of any meeting at which the holders of the preference shares represented by depositary shares are entitled to vote, the Bank Depositary will mail the notice to the record holders of the depositary shares relating to such preference shares. Each record holder of these depositary shares on the record date, which will be the same date as the record date for the preference shares, may instruct the Bank Depositary as to how to vote the preference shares represented by such holder’s depositary shares. The Bank Depositary will endeavor, insofar as practicable, to vote the amount of the preference shares represented by such depositary shares in accordance with such instructions, and we will take all action that the Bank Depositary deems necessary in order to enable the Bank Depositary to do so. The Bank Depositary will abstain from voting with respect to any preference shares to the extent it does not receive specific instructions from the holders of depositary shares representing such preference shares.

Amendment and Termination of the Depositary Agreement

The form of depositary receipt evidencing the depositary shares and any provision of the depositary agreement may be amended by agreement between the Bank Depositary and us. However, any amendment that materially and adversely alters the rights of the holders of depositary shares will not be effective unless such amendment has been approved by the holders of at least a majority of the depositary shares then outstanding. The depositary agreement may be terminated by the Bank Depositary or us only if (1) all outstanding depositary shares have been redeemed or (2) there has been a final distribution in respect of the preference shares in connection with any liquidation, dissolution or winding up of our company and such distribution has been distributed to the holders of depositary receipts.

Withdrawal of Preference Shares

Except as may be provided otherwise in an accompanying prospectus supplement, upon surrender of depositary receipts at the principal office of the Bank Depositary, subject to the terms of the depositary agreement, the owner of the depositary shares may demand delivery of the number of whole preference shares and all money and other property, if any, represented by those depositary shares. Partial preference shares will not be issued. If the depositary receipts delivered by the holder evidence a number of depositary shares in excess of the number of depositary shares representing the number of whole preference shares to be withdrawn, the Bank Depositary will deliver to such holder at the same time a new depositary receipt evidencing the excess number of depositary shares. Holders of withdrawn preference shares may not thereafter deposit those shares under the depositary agreement or receive depositary receipts evidencing depositary shares therefor.

General

We may sell the debt securities, including original issue discount securities, at par or at a substantial discount below their stated principal amount. Unless we inform you otherwise in an accompanying prospectus supplement, we may issue additional debt securities of a particular series without the consent of the holders of the debt securities of such series or any other series outstanding at the time of issuance. Any such additional debt securities, together with all other outstanding debt securities of that series, will constitute a single series of securities under the indenture.

We will describe in an accompanying prospectus supplement any other special considerations for any debt securities we sell that are denominated in a currency or currency unit other than U.S. dollars. In addition, debt securities may be issued where the amount of principal and/or interest payable is determined by reference to one or more currency exchange rates, commodity prices, equity indices or other factors. Holders of such securities may receive a principal amount or a payment of interest that is greater than or less than the amount of principal or interest otherwise payable on such dates, depending upon the value of the applicable currencies, commodities, equity indices or other factors. Information as to the methods for determining the amount of principal or interest, if any, payable on any date, and the currencies, commodities, equity indices or other factors to which the amount payable on such date is linked will be described in an accompanying prospectus supplement.

United States federal income tax consequences and special considerations, if any, applicable to any such series will be described in an accompanying prospectus supplement.

We expect most debt securities to be issued in fully registered form without coupons and in denominations of $2,000 and any integral multiple of $1,000 in excess thereof. Subject to the limitations provided in the indenture and in an accompanying prospectus supplement, debt securities that are issued in registered form may be transferred or exchanged at the designated corporate trust office of the trustee, without the payment of any service charge, other than any tax or other governmental charge payable in connection therewith.

Global Securities

Unless we inform you otherwise in an accompanying prospectus supplement, the debt securities of a series may be issued in whole or in part in the form of one or more global securities that will be deposited with, or on

15

behalf of, a depositary identified in an accompanying prospectus supplement. Unless and until a global security is exchanged in whole or in part for the individual debt securities, a global security may not be transferred except as a whole by the depositary for such global security to a nominee of such depositary or by a nominee of such depositary to such depositary or another nominee of such depositary or by such depositary or any such nominee to a successor of such depositary or a nominee of such successor.

Governing Law

The indenture and the debt securities shall be construed in accordance with and governed by the laws of the State of New York.

DESCRIPTION OF WARRANTS

We may issue warrants for the purchase of our common shares, preference shares or debt securities. We may issue warrants independently or together with other securities, and they may be attached to or separate from the other securities. Each series of warrants will be issued under a separate warrant agreement that we will enter into with a bank or trust company, as warrant agent, as detailed in an accompanying prospectus supplement. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation, or agency or trust relationship, with you. As used in this “Description of Warrants,” the terms “we” and “our” refer to Triton International Limited, a Bermuda exempted company, and do not, unless otherwise specified, include our subsidiaries.

The prospectus supplement relating to a particular issue of warrants will describe the terms of those warrants, including, when applicable:

• the offering price;

• the currency or currencies, including composite currencies, in which the purchase price and/or exercise price of the warrants may be payable;

• the number of warrants offered;

• the exercise price and the amount of securities you will receive upon exercise;

• the procedure for exercise of the warrants and the circumstances, if any, that will cause the warrants to be automatically exercised;

• the rights, if any, we have to redeem the warrants;

• the date on which the right to exercise the warrants will commence and the date on which the warrants will expire;

• the name of the warrant agent; and

• any other material terms of the warrants.

After warrants expire, they will become void. The prospectus supplement may provide for the adjustment of the exercise price of the warrants.

Warrants may be exercised at the appropriate office of the warrant agent or any other office indicated in an accompanying prospectus supplement. Before the exercise of warrants, holders will not have any of the rights of holders of the securities purchasable upon exercise and will not be entitled to payments made to holders of those securities.

The description in an accompanying prospectus supplement of any warrants we offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable warrant agreement, which will be

16

filed with the SEC if we offer warrants. For more information on how you can obtain copies of any warrant agreement if we offer warrants, see “Where You Can Find More Information.” We urge you to read the applicable warrant agreement and any accompanying prospectus supplement in their entirety.

DESCRIPTION OF SUBSCRIPTION RIGHTS

We may issue subscription rights to purchase our common shares, preference shares or debt securities. We may issue subscription rights independently or together with any other offered security, which may or may not be transferable by the shareholder. In connection with any offering of subscription rights, we may enter into a standby arrangement with one or more underwriters or other purchasers pursuant to which the underwriters or other purchasers may be required to purchase any securities remaining unsubscribed for after such offering. As used in this “Description of Subscription Rights,” the terms “we,” “our” and “us” refer to Triton International Limited, a Bermuda exempted company, and do not, unless otherwise specified, include our subsidiaries.

The prospectus supplement relating to any subscription rights we may offer will contain the specific terms of the subscription rights. These terms may include the following:

• the price, if any, for the subscription rights;

• the number and terms of each share of common shares or preference shares or debt securities which may be purchased per each subscription right;

• the exercise price payable for each share of common shares or preference shares or debt securities upon the exercise of the subscription rights;

• the extent to which the subscription rights are transferable;

• any provisions for adjustment of the number or amount of securities receivable upon exercise of the subscription rights or the exercise price of the subscription rights;

• any other terms of the subscription rights, including the terms, procedures and limitations relating to the exchange and exercise of the subscription rights;

• the date on which the right to exercise the subscription rights shall commence, and the date on which the subscription rights shall expire;

• the extent to which the subscription rights may include an over-subscription privilege with respect to unsubscribed securities; and

• if applicable, the material terms of any standby underwriting or purchase arrangement entered into by us in connection with the offering of subscription rights.

The description in an accompanying prospectus supplement of any subscription rights we offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable subscription rights certificate or subscription rights agreement, which will be filed with the SEC if we offer subscription rights. For more information on how you can obtain copies of any subscription rights certificate or subscription rights agreement if we offer subscription rights, see “Where You Can Find More Information.” We urge you to read the applicable subscription rights certificate, the applicable subscription rights agreement and any accompanying prospectus supplement in their entirety.

DESCRIPTION OF PURCHASE CONTRACTS AND PURCHASE UNITS

We may issue purchase contracts, including contracts obligating holders to purchase from us, and obligating us to sell to the holders, a specified number of our common shares, preference shares or debt securities at a future

17

date or dates, which we refer to in this prospectus as purchase contracts. The price of the securities and the number of securities may be fixed at the time the purchase contracts are issued or may be determined by reference to a specific formula set forth in the purchase contracts, and may be subject to adjustment under anti-dilution formulas. The purchase contracts may be issued separately or as part of units consisting of a stock purchase contract and our debt securities or preferred securities or debt obligations of third parties, including U.S. treasury securities, or any combination of the foregoing, securing the holders’ obligations to purchase the securities under the purchase contracts, which we refer to herein as purchase units. The purchase contracts may require holders to secure their obligations under the purchase contracts in a specified manner. The purchase contracts also may require us to make periodic payments to the holders of the purchase contracts or the purchase units, as the case may be, or vice versa, and those payments may be unsecured orpre-funded in whole or in part.

The description in an accompanying prospectus supplement of any purchase contract or purchase unit we offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable purchase contract or purchase unit, which will be filed with the SEC if we offer purchase contracts or purchase units. For more information on how you can obtain copies of any purchase contract or purchase unit we may offer, see “Where You Can Find More Information.” We urge you to read the applicable purchase contract or applicable purchase unit and any accompanying prospectus supplement in their entirety.

SELLING SECURITYHOLDERS

Information about selling securityholders, where applicable, will be set forth in a prospectus supplement, in a post-effective amendment or in filings we make with the SEC under the Exchange Act which are incorporated by reference into this prospectus.

PLAN OF DISTRIBUTION

We or the selling securityholders may sell the securities being offered hereby in one or more of the following ways from time to time:

• to underwriters for resale to purchasers;

• directly to purchasers;

• through agents or dealers to purchasers; or

• through a combination of any of these methods.

In addition, we may enter into derivative or hedging transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. In connection with such a transaction, the third parties may sell securities covered by and pursuant to this prospectus and any accompanying prospectus supplement. If so, the third party may use securities borrowed from us or others to settle such sales and may use securities received from us to close out any related short positions. We may also loan or pledge securities covered by this prospectus and any accompanying prospectus supplement to third parties, who may sell the loaned securities or, in an event of default in the case of a pledge, sell the pledged securities pursuant to this prospectus and any accompanying prospectus supplement.

The distribution of the securities offered under this prospectus may occur from time to time in one or more transactions at a fixed price or prices, which may be changed, at market prices prevailing at the time of sale, at prices related to the prevailing market prices or at negotiated prices.

We will identify the applicable specific plan of distribution, including any underwriters, dealers, agents or direct purchasers and their compensation in a prospectus supplement.

18

We may agree with any underwriters, dealers and agents to indemnify them against certain civil liabilities, including liabilities under the Securities Act or to contribute with respect to payments that such underwriters, dealers or agents may be required to make as a result of those certain civil liabilities.

All securities we may offer, other than common shares, will be new issues of securities with no established trading market. We may elect to list any series of securities on an exchange, and, in the case of our common shares, on any additional exchange, but, unless otherwise specified in the applicable prospectus supplement, we shall not be obligated to do so. If we sell a security offered by this prospectus to an underwriter for public offering and sale, the underwriter may make a market for that security, but the underwriter will not be obligated to do so and could discontinue any market making without notice at any time. Therefore, we cannot give any assurances to you concerning the liquidity of any security offered by this prospectus.

Underwriters and agents and their affiliates may be customers of, engage in transactions with, or perform services for us or our subsidiaries in the ordinary course of their businesses.

Unless otherwise indicated in any accompanying prospectus supplement, Appleby (Bermuda) Limited will provide opinions regarding the authorization and validity of the securities. Skadden, Arps, Slate, Meagher & Flom LLP may also provide opinions regarding certain other matters. Any underwriters will be advised about legal matters by their own counsel, which will be named in an accompanying prospectus supplement.
