TABLE OF CONTENTS
ABOUT THIS PROSPECTUS SUPPLEMENT
This prospectus supplement and the accompanying prospectus are part of a registration statement that we filed with the Commission utilizing a “shelf” registration process. This document is in two parts. The first part is this prospectus supplement, which describes the specific terms of this offering of common shares and also adds to and updates information contained in the accompanying base prospectus and the documents incorporated by reference into this prospectus supplement and the base prospectus. The second part, the base prospectus, gives more general information about securities we may offer from time to time, some of which does not apply to this offering. Generally, when we refer only to the prospectus, we are referring to both parts combined, and when we refer to the accompanying prospectus, we are referring to the base prospectus.
If the description of this offering varies between this prospectus supplement and the accompanying base prospectus, you should rely on the information in this prospectus supplement. This prospectus supplement, the accompanying base prospectus and the documents incorporated into each by reference include important information about us, the common shares being offered and other information you should know before investing. You should read this prospectus supplement and the accompanying base prospectus together with additional information described under the heading, “Where You Can Find Additional Information” before investing in our common shares.
We prepare our financial statements, including all of the financial statements incorporated by reference in this prospectus supplement, in U.S. dollars and in accordance with International Financial Reporting Standards, or IFRS, as issued by the International Accounting Standards Board, or IASB. We have a fiscal year end of December 31.
We have authorized only the information contained or incorporated by reference in this prospectus supplement, the accompanying base prospectus and any free writing prospectus prepared by or on behalf of us or to which we have referred you. We have not, and the underwriters have not, authorized anyone to provide you with information that is different. We and the underwriters take no responsibility for, and can provide no assurance as to the reliability of, any information that others may give you. We are offering to sell, and seeking offers to buy, our common shares only in jurisdictions where offers and sales are permitted. The information contained in or incorporated by reference in this document is accurate only as of the date such information was issued, regardless of the time of delivery of this prospectus supplement or any sale of our common shares.

CAUTIONARY STATEMENT REGARDING FORWARD LOOKING STATEMENTS
The Private Securities Litigation Reform Act of 1995 provides safe harbor protections for forward-looking statements in order to encourage companies to provide prospective information about their business. Forward-looking statements include statements concerning plans, objectives, goals, strategies, future events or performance, and underlying assumptions and other statements, which are other than statements of historical facts.
This document includes assumptions, expectations, projections, intentions and beliefs about future events. These statements are intended as “forward-looking statements.” We desire to take advantage of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 and are including this cautionary statement in connection therewith. This document and the documents incorporated by reference herein and any other written or oral statements made by us or on our behalf may include forward-looking statements, which reflect our current views with respect to future events and financial performance, and are not intended to give any assurance as to future results or events. We caution that assumptions, expectations, projections, intentions and beliefs about future events may and often do vary from actual results and the differences can be material. When used in this document, the words “believe,” “expect,” “anticipate,” “estimate,” “intend,” “plan,” “target,” “project,” “likely,” “may,” “will,” “would,” “could” and similar expressions, terms, or phrases may identify forward-looking statements.
The forward-looking statements in this document and the documents incorporated by reference herein are based upon various assumptions, many of which are based, in turn, upon further assumptions, including without limitation, management’s examination of historical operating trends, data contained in our records and other data available from third parties. Although we believe that these assumptions were reasonable when made, because these assumptions are inherently subject to significant uncertainties and contingencies which are difficult or impossible to predict and are beyond our control, we cannot assure you that we will achieve or accomplish these expectations, beliefs or projections.
In addition to important factors and matters discussed elsewhere in this prospectus supplement, the accompanying prospectus, and the documents incorporated into each by reference, important factors that, in our view, could cause our actual results to differ materially from those discussed in the forward-looking statements include:

the strength of world economies and currencies;

general market conditions, including the market for our vessels, fluctuations in spot and charter rates and vessel values;

the performance of our newbuilding vessels;

availability of financing and refinancing;

potential liability from pending or future litigation;

general domestic and international political conditions;

potential disruption of shipping routes due to accidents or political events;

vessels breakdowns and instances of off-hires;

competition within our industry;

the supply of and demand for vessels comparable to ours;

corruption, piracy, militant activities, political instability, terrorism, ethnic unrest in locations where we may operate;

delays and cost overruns in construction projects;

our level of indebtedness;

our ability to obtain financing and comply with the restrictive and other covenants in our financing arrangements;
S-iii

TABLE OF CONTENTS

our need for cash to meet our debt service obligations;

our levels of operating and maintenance costs, including bunker prices, drydocking and insurance costs;

our ability to successfully identify, consummate, integrate, and realize the expected benefits from acquisitions;

availability of skilled workers and the related labor costs;

compliance with, and liabilities under, governmental, tax, environmental and safety regulation, including, but not limited to, recent regulations governing ballast water treatment and sulfur emissions;

any non-compliance with the U.S. Foreign Corrupt Practices Act of 1977 (FCPA) or other applicable regulations relating to bribery;

general economic conditions and conditions in the oil and natural gas industry;

effects of new products and new technology in our industry;

the failure of counterparties to fully perform their contracts with us;

our dependence on key personnel;

adequacy of our insurance coverage;

our ability to obtain indemnities from customers;

changes in laws, treaties or regulations applicable to us;

the volatility of the price of our common shares;

other important factors described in “Risk Factors” beginning on page S-13 and the documents incorporated by reference in this prospectus supplement; and

other important factors described from time to time in the reports we file and furnish with the Commission.
These factors and the other risk factors described in this prospectus supplement, the accompanying base prospectus, and the documents incorporated by reference into each, are not necessarily all of the important factors that could cause actual results or developments to differ materially from those expressed in any of our forward-looking statements. Other unknown or unpredictable factors also could harm our results. Consequently, there can be no assurance that 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, us. These forward-looking statements are not guarantees of our future performance, and actual results and future developments may vary materially from those projected in the forward-looking statements. Given these uncertainties, prospective investors are cautioned not to place undue reliance on such forward-looking statements, which speak only as of their dates. We undertake no obligation, and specifically decline any obligation, except as required by law, to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. For a discussion of these risks and uncertainties, please see the section of this prospectus supplement entitled “Risk Factors.”

end of the seventh year equal to the outstanding principal amount at that date. We are subject to certain additional terms and conditions under this arrangement, including financial covenants, which are similar to those set forth in our existing lease financing arrangements. These transactions are expected to close in October 2018.
Convertible Notes due 2019 Exchange
In July 2018, we exchanged $15.0 million in aggregate principal amount of our convertible senior notes that mature in 2019 (the “Convertible Notes due 2019”) for $15.0 million in aggregate principal amount of the Company’s convertible senior notes that mature in 2022 (the “Convertible Notes due 2022”). The new notes issued in this exchange have identical terms, are fungible with and are part of the series of Convertible Notes due 2022, which were issued in May 2018. This exchange was executed with certain holders of the Convertible Notes due 2019 through separate, privately negotiated agreements.
Amendment of Minimum Interest Coverage Ratio
In September 2018, we entered into agreements with certain lenders who are party to credit facilities with us to permanently remove the minimum interest coverage ratio financial covenant from the terms of each facility. As a result, the Company is no longer required to maintain a ratio of EBITDA to net interest expense on any of its secured credit facilities or lease financing arrangements.
As part of these agreements, and for certain other facilities, the minimum threshold for the aggregate fair market value of the vessels as a percentage of the then aggregate principal amount each facility was revised to be no less than the following:
Facility
Minimum ratio
KEXIM Credit Facility
155%
2017 Credit Facility
155%
2016 Credit Facility
145% through June 30, 2019, 150% thereafter
ABN Credit Facility
145% through June 30, 2019, 150% thereafter
DVB Credit Facility
145% through June 30, 2019, 150% thereafter
Retrofitting of our Fleet
On September 28, 2018, we announced that management expects to retrofit the substantial majority of our vessels with exhaust gas cleaning systems, or scrubbers, to comply with the IMO 2020 rules regarding sulfur emissions by the end of the first half of 2020. We expect the aggregate capital investment of such retrofits to be material, but we have not determined the exact costs or how such costs will be financed. As of October 8, 2018, we have entered into an agreement to retrofit 15 of our LR2s with such systems, which are expected to be installed throughout 2019. The total estimated investment for these systems, including installation, is expected to be between $1.5 and $2.0 million per vessel and we are currently in preliminary discussions with potential lenders to finance a portion (60-70%) of these investments.
Declaration of Dividend
On July 30, 2018, our Board of Directors declared a quarterly cash dividend of  $0.01 per share, which was paid on September 27, 2018 to all shareholders as of September 20, 2018.
Reduction in Commercial Management Fee
In September 2018, we entered into an agreement with our commercial manager, Scorpio Commercial Management S.A.M. (“SCM”), a related party, whereby SCM will reimburse certain of the commissions that SCM charges with respect to our vessels to effectively reduce such commissions to 0.85% of the gross revenue per charter fixture, effective from September 1, 2018 and ending on June 1, 2019.

Our Chartering Strategy
Generally, we operate our vessels in commercial pools, on time charters or in the spot market.
Commercial Pools
To increase vessel utilization and thereby revenues, we participate in commercial pools with other shipowners of similar modern, well-maintained vessels. By operating a large number of vessels as an integrated transportation system, commercial pools offer customers greater flexibility and a higher level of service while achieving scheduling efficiencies. Pools employ experienced commercial managers and operators who have close working relationships with customers and brokers, while technical management is performed by each shipowner. Pools negotiate charters with customers primarily in the spot market, but may also arrange time charter agreements. The size and scope of these pools enable them to enhance utilization rates for pool vessels by securing backhaul voyages and contracts of affreightment, or COAs,

thus generating higher effective time charter equivalent, or TCE, revenues than otherwise might be obtainable in the spot market. As of October 8, 2018, 117 of the vessels in our Operating Fleet operate in, or are expected to operate in, one of the Scorpio Group Pools.
Time Charters
Time charters give us a fixed and stable cash flow for a known period of time. Time charters also mitigate in part the seasonality of the spot market business, which is generally weaker in the second and third quarters of the year. In the future, we may opportunistically look to enter our vessels into time charter contracts. We may also enter into time charter contracts with profit sharing agreements, which enable us to benefit if the spot market increases. As of October 8, 2018, five of the vessels in our Operating Fleet are employed under long-term time charters (with initial terms of one year or greater).
Spot Market
A spot market voyage charter is generally a contract to carry a specific cargo from a load port to a discharge port for an agreed freight per ton of cargo or a specified total amount. Under spot market voyage charters, we pay voyage expenses such as port, canal and bunker costs. Spot charter rates are volatile and fluctuate on a seasonal and year-to-year basis. Fluctuations derive from imbalances in the availability of cargoes for shipment and the number of vessels available at any given time to transport these cargoes. Vessels operating in the spot market generate revenue that is less predictable, but may enable us to capture increased profit margins during periods of improvements in tanker rates. We also consider short-term time charters (with initial terms of less than one year) as spot market voyages. We did not have any vessels operating directly in the spot market as October 8, 2018.
Management of Our Fleet
Our vessels are commercially managed by SCM, and technically managed by Scorpio Ship Management S.A.M., or SSM, each a related party of us and a member of the Scorpio Group, pursuant to an Amended and Restated Master Agreement. On February 22, 2018, we entered into definitive documentation to memorialize previously agreed amendments to the Amended and Restated Master Agreement under a deed of amendment, or the Amendment Agreement. The Amended and Restated Master Agreement as amended by the Amendment Agreement, or the Revised Master Agreement, is effective as from January 1, 2018. The Revised Master Agreement may be terminated by either party upon 24 months’ notice, unless terminated earlier in accordance with the provisions thereof. In the event of the sale of one or more vessels, a notice period of three months and a payment equal to three months of management fees will apply, provided that the termination does not amount to a change in control, including a sale of all or substantially all of our vessels, in which case a payment equal to 24 months of management fees will apply. We expect that additional vessels we acquire in the future will also be managed under the Revised Master Agreement or on substantially similar terms.
In addition, Scorpio Services Holding Limited, or SSH, provides us with certain administrative services pursuant to an Amended Administrative Services Agreement, which may be terminated by us upon two years notice. Our arrangements with SCM, SSM and SSH are described in further detail below.
Commercial Management. SCM’s services include securing employment, in the spot market and on time charters, for our vessels. SCM also manages the Scorpio Group Pools. When our vessels are operating in one of the Scorpio Group Pools, SCM, the pool manager, charges fees of  $300 per vessel per day with respect to our LR1/Panamax and Aframax vessels, $250 per vessel per day with respect to our LR2 vessels, and $325 per vessel per day with respect to each of our Handymax and MR vessels, plus 1.50% commission on gross revenues per charter fixture. These are the same fees that SCM charges other vessel owners in these pools, including third-party owned vessels. For commercial management of our vessels that are not operating in any of the Scorpio Group Pools, we pay SCM a fee of  $250 per vessel per day for each LR1/Panamax and LR2/Aframax vessel and $300 per vessel per day for each Handymax and MR vessel, plus 1.25% commission on gross revenues per charter fixture. In September 2018, we entered into an agreement with SCM, whereby SCM will reimburse certain of the commissions that SCM charges with respect to our vessels to effectively reduce such commissions to 0.85% of the gross revenue per charter fixture, effective from September 1, 2018 and ending on June 1, 2019.

TABLE OF CONTENTS
Technical Management. SSM’s services include day-to-day vessel operations, performing general maintenance, monitoring regulatory and classification society compliance, customer vetting procedures, supervising the maintenance and general efficiency of vessels, arranging the hiring of qualified officers and crew, arranging and supervising drydocking and repairs, purchasing supplies, spare parts and new equipment for vessels, appointing supervisors and technical consultants and providing technical support. Pursuant to the Revised Master Agreement, which was effective as from January 1, 2018, the fixed annual technical management fee was reduced from $250,000 per vessel to $175,000 per vessel and certain services previously provided as part of the fixed fee are now itemized. The aggregate cost, including the costs that are now itemized, for the services provided under the technical management agreement, did not and are not expected to materially differ from the annual technical management fee charged prior to the amendment.
Administrative Services. SSH’s administrative services include the provision of administrative staff and office space, and administrative services, including accounting, legal compliance, financial and information technology services. We reimburse SSH for the reasonable direct or indirect expenses it incurs in providing us with the administrative services described above. The services provided to us by SSH may be sub-contracted to other entities within the Scorpio Group. Further, SSH has agreed, on behalf of itself and other members of the Scorpio Group, that it will not directly own product or crude tankers ranging in size from 35,000 dwt to 200,000 dwt.
Our Relationship with Scorpio Group and its Affiliates
We believe that one of our principal strengths is our relationship with the Scorpio Group. Our vessel operations are managed under the supervision of our board of directors, by our management team and by members of the Scorpio Group, including SCM and SSM. Our relationship with the Scorpio Group provides access to the Scorpio Group’s customer and supplier relationships and their technical, commercial and managerial expertise, which we believe allows us to compete more effectively and operate our vessels on a cost efficient basis. We can provide no assurance, however, that we will realize any benefits from our relationship with the Scorpio Group.
Certain companies within the Scorpio Group are owned and controlled by the Lolli-Ghetti family, including Emanuele Lauro, our Founder, Chairman and Chief Executive Officer, and Filippo Lauro, our Vice President. In addition, certain of our executive officers serve in similar management positions in certain companies within the Scorpio Group and have minority equity interests in SSH, the company that provides us with certain administrative services.
These responsibilities and relationships could create conflicts of interest between us, on the one hand, and SCM, SSM, SSH, or other Scorpio Group companies, on the other hand. These conflicts may arise in connection with the chartering, purchase, sale and operation of the vessels in our fleet versus vessels managed by other members of the Scorpio Group. For example, SCM and SSM, our commercial manager and technical manager, respectively, may give preferential treatment to vessels that are time chartered-in by related parties because Messrs. Lauro and members of their family may receive greater economic benefits. As a result of these conflicts, such Scorpio Group companies, who have limited contractual duties, may favor their own or other owner’s interests over our interests. These conflicts may have unfavorable results for us and our shareholders.

TABLE OF CONTENTS
RISK FACTORS
An investment in our common shares involves a high degree of risk. Before making an investment in our common shares, you should carefully consider the risk factors and all of the other information included in this prospectus supplement, the accompanying base prospectus and the documents incorporated into each by reference, including those in “Item 3. Key Information—D. Risk Factors” in our Annual Report on Form 20-F for the year ended December 31, 2017, filed with the Commission on March 23, 2018, as updated by annual, quarterly and other reports and documents we file with the Commission after the date of this prospectus supplement and that are incorporated by reference herein. Please see the section of this prospectus supplement entitled “Where You Can Find Additional Information—Information Incorporated by Reference.” The occurrence of one or more of those risk factors could adversely impact our business, financial condition or results of operations.
The price of our common shares after this offering may be volatile.
The price of our common shares may fluctuate due to factors such as:

actual or anticipated fluctuations in our quarterly and annual results and those of other public companies in our industry;

mergers and strategic alliances in the crude tanker and product tanker industries;

market conditions in the crude tanker and product tanker industries;

changes in government regulation;

the failure of securities analysts to publish research about us after this offering, or shortfalls in our operating results from levels forecast by securities analysts;

announcements concerning us or our competitors; and

the general state of the securities market.
The seaborne transportation industry has been highly unpredictable and volatile. The market for our common shares in this industry may be equally volatile. Consequently, you may not be able to sell the common shares at prices equal to or greater than those paid by you in this offering.
We may issue additional common shares or other equity securities without your approval, which would dilute your ownership interests and may depress the market price of our common shares.
We may issue additional common shares or other equity securities of equal or senior rank in the future in connection with, among other things, future vessel acquisitions, repayment of outstanding indebtedness, or our equity incentive plan, without shareholder approval, in a number of circumstances.
Our issuance of additional common shares or other equity securities of equal or senior rank would have the following effects:

our existing shareholders’ proportionate ownership interest in us will decrease;

the amount of cash available for dividends payable on our common shares may decrease;

the relative voting strength of each previously outstanding common share may be diminished; and

the market price of our common shares may decline.

TABLE OF CONTENTS
DILUTION
Dilution or accretion is the amount by which the offering price paid by the purchasers of our common shares in this offering will differ from the net tangible book value per common share after the offering. The net tangible book value is equal to the amount of our total tangible assets (total assets less intangible assets) less total liabilities. The historical net tangible book value and the as adjusted (1) net tangible book value as of June 30, 2018 were $1.6 billion in total and $4.83 per share for the number of outstanding shares at that date (in addition to 2.1 million restricted shares that were granted to our employees and directors in September 2018).
The as further adjusted net tangible book value as of June 30, 2018 would have been $1.9 billion, or $3.83 per common share after the issuance and sale by us of common shares at $1.85 per share in this offering, after deducting estimated expenses related to this offering. This represents an immediate decrease in net tangible book value of  $1.00 per share to the existing shareholders and an immediate accretion in net tangible book value of  $1.98 per share to new investors.
The following table illustrates the pro forma per share accretion and decrease in net tangible book value as of June 30, 2018:

Clarksons Platou Securities AS is not a US registered broker-dealer and, therefore, intends to participate in the offering outside of the United States and, to the extent that any offering by Clarksons Platou Securities AS is within the United States, Clarksons Platou Securities AS will offer to and place securities with investors through Clarksons Platou Securities, Inc., an affiliated US broker-dealer. The activities of Clarksons Platou Securities AS in the United States will be effected only to the extent permitted by Rule 15a-6 under the Securities Exchange Act of 1934, as amended.
The underwriters are offering the common shares subject to their acceptance of the shares from us and subject to prior sale. The underwriting agreement provides that the obligations of the several underwriters to pay for and accept delivery of the common shares offered by this prospectus are subject to the approval of certain legal matters by their counsel and to certain other conditions. The underwriters are obligated to take and pay for all of the common shares offered by this prospectus if any such shares are taken. However, the underwriters are not required to take or pay for the shares covered by the underwriters’ option to purchase additional shares described below.
The underwriters initially propose to offer part of the common shares directly to the public at the offering price listed on the cover page of this prospectus and part to certain dealers. After the initial offering of the common shares, the offering price and other selling terms may from time to time be varied by the representatives.
We have granted to the underwriters an option, exercisable for 30 days from the date of this prospectus, to purchase up to 24,324,324 additional common shares at the public offering price listed on the cover page of this prospectus, less underwriting discounts and commissions, provided, however, that the amount paid by the underwriters for any additional shares shall be reduced by an amount per share equal to any dividends declared by us and payable on the common shares but not payable on such additional shares. To the extent the option is exercised, each underwriter will become obligated, subject to certain conditions, to purchase approximately the same percentage of the additional common shares as the number listed next to the underwriter’s name in the preceding table bears to the total number of common shares listed next to the names of all underwriters in the preceding table.
The following table shows the per share and total public offering price, underwriting discounts and commissions and proceeds before expenses to us.

New York Stock Exchange Listing
The shares are listed on the New York Stock Exchange under the symbol “STNG.”
Price Stabilization, Short Positions
Until the distribution of the shares is completed, SEC rules may limit underwriters and selling group members from bidding for and purchasing our common stock. However, the representatives may engage in transactions that stabilize the price of the common stock, such as bids or purchases to peg, fix or maintain that price.
In connection with the offering, the underwriters may purchase and sell our common stock in the open market. These transactions may include short sales, purchases on the open market to cover positions created by short sales and stabilizing transactions. Short sales involve the sale by the underwriters of a greater number of shares than they are required to purchase in the offering. “Covered” short sales are sales made in an amount not greater than the underwriters’ option to purchase additional shares described above. The underwriters may close out any covered short position by either exercising their option to purchase additional shares or purchasing shares in the open market. In determining the source of shares to close out the covered short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the option granted to them. “Naked” short sales are sales in excess of such option. The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of our common stock in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of various bids for or purchases of shares of common stock made by the underwriters in the open market prior to the completion of the offering.
Similar to other purchase transactions, the underwriters’ purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of our common stock. As a result, the price of our common stock may be higher than the price that might otherwise exist in the open market. The underwriters may conduct these transactions on the New York Stock Exchange, in the over-the-counter market or otherwise.
Neither we nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our common stock. In addition, neither we nor any of the underwriters make any representation that the representatives will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.
Electronic Distribution
In connection with the offering, certain of the underwriters or securities dealers may distribute prospectuses by electronic means, such as e-mail.
Other Relationships
Some of the underwriters and their 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 underwriters and their 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

The above selling restriction is in addition to any other selling restrictions set out below.

PROSPECTUS SUMMARY
This section summarizes some of the key information that is contained or incorporated by reference in this prospectus. It may not contain all of the information that may be important to you. As an investor or prospective investor, you should review carefully the entire prospectus and the information incorporated by reference herein, including the section entitled “Risk Factors.”
Our Company
Scorpio Tankers Inc. was incorporated in the Republic of the Marshall Islands pursuant to the Marshall Islands Business Corporations Act on July 1, 2009. We provide seaborne transportation of refined petroleum products worldwide. We began our operations in October 2009 with three vessel owning and operating subsidiary companies. In April 2010, we completed our initial public offering of common stock and commenced trading on the NYSE under the symbol “STNG.” We have since expanded our fleet and as of the date of this prospectus, our fleet consists of 78 wholly owned product tankers (consisting of 18 LR2 tankers, 14 Handymax tankers and 46 MR tankers) with an average age of approximately 1.5 years, and 11 time or bareboat chartered-in product tankers that we operate (consisting of three Handymax tankers, four MR tankers, one LR1 tanker and three LR2 tankers), which we refer to collectively as our Operating Fleet. In addition, we currently have contracts for the construction of 12 newbuilding product tankers (consisting of eight MR tankers and four LR2 tankers), which we refer to as our Newbuilding Program. Of the vessels in our Newbuilding Program, the four LR2 tankers are expected to be delivered to us in throughout 2016 (one per quarter) and the eight MR tankers are expected to be delivered to us throughout 2017. We have also reached an agreement to sell four of our 2014-built MRs to an unrelated third party. These sales are expected to close in the first and second quarters of 2016.
Corporate Structure
We were incorporated in the Republic of the Marshall Islands pursuant to the Marshall Islands Business Corporation Act on July 1, 2009. We currently maintain our principal executive offices at 9, Boulevard Charles III, Monaco 98000 and our telephone number at that location is +377-9798-5716. We also maintain an office in the United States at 150 East 58th Street, New York, New York 10155 and the telephone number at that address is 212-542-1616. We own each of the vessels in our owned fleet, and expect to own each additional vessel that we acquire into our owned fleet in the future, through separate wholly-owned subsidiaries incorporated in the Republic of the Marshall Islands. The vessels in our time chartered-in fleet are chartered-in to our wholly-owned subsidiary, STI Chartering and Trading Ltd.
RECENT AND OTHER DEVELOPMENTS
Agreement to Sell Five MR Product Tankers
In February 2016, we reached an agreement with an unrelated third party to sell five 2014-built MR product tankers (STI Powai, STI Lexington, STI Chelsea, STI Olivia and STI Mythos) for approximately $33.3 million each. The sale of STI Lexington closed in March 2016 and the sales of the remaining four vessels are expected to close by June 2016. As a result of the closing of the sale of STI Lexington, we repaid $18.4 million on our K-Sure Credit Facility and expect to write-off  $0.7 million of deferred financing fees during the first quarter of 2016. We expect to record an aggregate write-down on the sales of all five vessels of approximately $3.2 million during the first quarter of 2016 in connection with these transactions.
Time Chartered-In Vessels
In March 2016, we entered into time charter-in agreements with an unrelated third party on three ice class 1A Handymax product tankers. Each agreement is for three years at $15,600 per day and we have two consecutive one year options to extend the agreements at $16,500 per day and $17,500 per day, respectively. These time charters are expected to commence before the end of March 2016. In addition, we have the option to time charter-in up to four additional ice class 1A Handymax product tankers under the same terms.

In February 2016, we exercised an option to extend the charter on an LR1 product tanker that we currently time charter-in. The term of the original charter was for one year at $16,250 per day. The extended term is for an additional year at a rate of  $17,250 per day, commencing in March 2016.
Dividend Declaration
On February 25, 2016, our Board of Directors declared a quarterly cash dividend of  $0.125 per share, payable on March 30, 2016 to all shareholders of record as of March 10, 2016.
Credit Facilities
In March 2016, we drew down $26.0 million from our ING Credit Facility to partially finance the delivery of STI Grace, which is scheduled to occur on March 18, 2016.
In March 2016, we amended and restated our $87.0 million credit facility with ING Bank N.V. to increase the borrowing capacity to $132.5 million. The remaining terms and conditions of the facility remained unchanged and the proceeds from the increased borrowing capacity are expected to be used to partially finance the purchase of STI Lombard (currently bareboat chartered-in) and to refinance the existing indebtedness on an MR product tanker (2015-built).
We refinanced the outstanding indebtedness related to STI Battery by repaying $18.2 million on our 2013 Credit Facility in January 2016 and drawing down $17.25 million from our BNP Paribas Credit Facility in February 2016.
Convertible Senior Notes due 2019
Effective as of March 10, 2016, we adjusted the conversion rate of our Convertible Senior Notes due 2019, or the Notes, to reflect the payment of a cash dividend of  $0.125 on our common shares. The new conversion rate for the Notes is 90.5311 common shares per $1,000 principal amount of the Notes, representing an increase of the prior conversion rate of 1.8521 common shares for each $1,000 principal amount of the Notes.
$250 Million Securities Repurchase Program
In May 2015, our Board of Directors authorized a new Securities Repurchase Program to purchase up to an aggregate of  $250 million of our common stock and bonds, which currently consist of our (i) Convertible Senior Notes Due 2019, which were issued in June 2014, (ii) Unsecured Senior Notes Due 2020 (NYSE: SBNA), which were issued in May 2014, and (iii) Unsecured Senior Notes Due 2017 (NYSE: SBNB), which were issued in October 2014. This program replaces our stock buyback program that was previously announced in July 2014 and was terminated in conjunction with this new repurchase program.
Since January 1, 2016 through March 17, 2016, we have acquired an aggregate of 2,299,606 of our common shares that are being held as treasury shares at an average price of  $5.96 per share.
We have $164.5 million remaining under our Securities Repurchase Program as of March 17, 2016. We expect to repurchase any securities in the open market, at times and prices that are considered to be appropriate by us, but are not obligated under the terms of the program to repurchase any securities.

Before making an investment in our securities, you should carefully consider all of the information included or incorporated by reference into this prospectus and in any prospectus supplement, including the risks described under the heading “Risk Factors” in our Annual Report on Form 20-F filed with the Commission on March 18, 2016, as updated by annual and other reports and documents we file with the Commission after the date of this prospectus and that are incorporated by reference herein. Please see the section of this prospectus entitled “Where You Can Find Additional Information.”
The occurrence of one or more of those risk factors could adversely impact our business, financial condition or results of operations.

TABLE OF CONTENTS
CAUTIONARY STATEMENT REGARDING FORWARD LOOKING STATEMENTS
The Private Securities Litigation Reform Act of 1995 provides safe harbor protections for forward-looking statements in order to encourage companies to provide prospective information about their business. Forward-looking statements include statements concerning plans, objectives, goals, strategies, future events or performance, and underlying assumptions and other statements, which are other than statements of historical facts.
This prospectus includes assumptions, expectations, projections, intentions and beliefs about future events. These statements are intended as “forward-looking statements.” We desire to take advantage of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 and are including this cautionary statement in connection therewith. This prospectus and any other written or oral statements made by us or on our behalf may include forward-looking statements, which reflect our current views with respect to future events and financial performance, and are not intended to give any assurance as to future results or events. We caution that assumptions, expectations, projections, intentions and beliefs about future events may and often do vary from actual results and the differences can be material. When used in this prospectus, the words “believe,” “expect,” “anticipate,” “estimate,” “intend,” “plan,” “target,” “project,” “likely,” “may,” “will,” “would,” “could” and similar expressions, terms, or phrases may identify forward-looking statements.
The forward-looking statements in this prospectus are based upon various assumptions, many of which are based, in turn, upon further assumptions, including without limitation, management’s examination of historical operating trends, data contained in our records and other data available from third parties. Although we believe that these assumptions were reasonable when made, because these assumptions are inherently subject to significant uncertainties and contingencies which are difficult or impossible to predict and are beyond our control, we cannot assure you that we will achieve or accomplish these expectations, beliefs or projections.
In addition to important factors and matters discussed elsewhere in this prospectus and in the documents incorporated by reference herein, important factors that, in our view, could cause our actual results to differ materially from those discussed in the forward-looking statements include:

the strength of world economies and currencies;

general market conditions, including the market for our vessels, fluctuations in spot and charter rates and vessel values;

the cost of our newbuilding program and the delivery and performance of our newbuilding vessels;

availability of financing and refinancing;

potential liability from pending or future litigation;

general domestic and international political conditions;

potential disruption of shipping routes due to accidents or political events;

vessels breakdowns and instances of off-hires;

competition within our industry;

termination of our customer contracts;

the supply of and demand for vessels comparable to ours;

corruption, piracy, militant activities, political instability, terrorism, ethnic unrest in locations where we may operate;

delays and cost overruns in construction projects;

our level of indebtedness;

TABLE OF CONTENTS

our ability to obtain financing and comply with the restrictive and other covenants in our financing arrangements;

our need for cash to meet our debt service obligations;

our levels of operating and maintenance costs, including bunker prices, drydocking and insurance costs;

availability of skilled workers and the related labor costs;

compliance with governmental, tax, environmental and safety regulation;

any non-compliance with the U.S. Foreign Corrupt Practices Act of 1977 (FCPA) or other applicable regulations relating to bribery;

general economic conditions and conditions in the oil and natural gas industry;

effects of new products and new technology in our industry;

the failure of counterparties to fully perform their contracts with us;

our dependence on key personnel;

adequacy of our insurance coverage;

our ability to obtain indemnities from customers;

changes in laws, treaties or regulations applicable to us;

the volatility of the price of our common shares; and

other important factors described from time to time in the reports we file and furnish with the Commission.
These factors and the other risk factors described in this prospectus are not necessarily all of the important factors that could cause actual results or developments to differ materially from those expressed in any of our forward-looking statements. Other unknown or unpredictable factors also could harm our results. Consequently, there can be no assurance that 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, us. These forward-looking statements are not guarantees of our future performance, and actual results and future developments may vary materially from those projected in the forward-looking statements. Given these uncertainties, prospective investors are cautioned not to place undue reliance on such forward-looking statements, which speak only as of their dates. We undertake no obligation, and specifically decline any obligation, except as required by law, to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. For a discussion of these risks and uncertainties, please see the section of this prospectus entitled “Risk Factors.”

RATIO OF EARNINGS TO FIXED CHARGES
The following table sets forth our unaudited ratio of earnings to fixed charges for the periods presented.
Years ended December 31,
2015

2011
Ratio of earnings to fixed charges(1)
3.20x 1.80x 1.90x (2) (2)
(1)
For purposes of calculating the ratios of consolidated earnings to fixed charges:

“earnings” consist of net income before income or loss from associate as prepared under IFRS, plus fixed charges and the amortization of capitalized interest, net of capitalized interest; and

“fixed charges” represent interest expensed and capitalized, amortization of deferred financing fees (whether expensed or capitalized) and the Company’s estimate of the interest component of rent.
The ratios of earnings to fixed charges are ratios that we are required to present in this prospectus and have been calculated in accordance with Commission rules and regulations. These ratios have no application to any of our credit facilities or unsecured borrowings and we believe they are not ratios generally used by investors to evaluate our overall operating performance.
(2)
Our earnings were insufficient to cover fixed charges and accordingly, the ratio was less than 1:1. We would have needed to generate additional earnings of  $29.7 million and $83.3 million to achieve coverage of 1:1 in the years ended December 31, 2012 and 2011, respectively.

TABLE OF CONTENTS
PLAN OF DISTRIBUTION
We or any selling shareholder may sell or distribute our securities included in this prospectus through underwriters, through agents, to dealers, in private transactions, at market prices prevailing at the time of sale, at prices related to the prevailing market prices, or at negotiated prices.
In addition, we or the selling shareholders may sell some or all of our securities included in this prospectus through:

a block trade in which a broker-dealer may resell a portion of the block, as principal, in order to facilitate the transaction;

purchases by a broker-dealer, as principal, and resale by the broker-dealer for its account;

ordinary brokerage transactions and transactions in which a broker solicits purchasers; or

trading plans entered into by us pursuant to Rule 10b5-1 under the Securities Exchange Act of 1934, as amended, or the Exchange Act, that are in place at the time of an offering pursuant to this prospectus and any applicable prospectus supplement hereto that provide for periodic sales of their securities on the basis of parameters described in such trading plans.
In addition, we or the selling shareholders may enter into options or other types of transactions that require us or them to deliver our securities to a broker-dealer, who will then resell or transfer the securities under this prospectus. We or any selling shareholder may enter into hedging transactions with respect to our securities. For example, we or any selling shareholder may:

enter into transactions involving short sales of our common shares by broker-dealers;

sell common shares short and deliver the shares to close out short positions;

enter into option or other types of transactions that require us or the selling shareholder to deliver common shares to a broker-dealer, who will then resell or transfer the common shares under this prospectus; or

loan or pledge the common shares to a broker-dealer, who may sell the loaned shares or, in the event of default, sell the pledged shares.
We or any selling shareholder may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by us, any selling shareholder or borrowed from us or any selling shareholder or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us or any selling shareholder in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and, if not identified in this prospectus, will be identified in the applicable prospectus supplement (or a post-effective amendment). In addition, we or any selling shareholder may otherwise loan or pledge securities to a financial institution or other third party that in turn may sell the securities short using this prospectus. Such financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.
The selling shareholders and any broker-dealers or other persons acting on our behalf or on the behalf of the selling shareholders that participate with us or the selling shareholders in the distribution of the securities may be deemed to be underwriters and any commissions received or profit realized by them on the resale of the securities may be deemed to be underwriting discounts and commissions under the Securities Act of 1933, as amended, or the Securities Act. As a result, we have or will inform the selling shareholders that Regulation M, promulgated under the Exchange Act, may apply to sales by the selling shareholders in the market. The selling shareholders may agree to indemnify any broker, dealer or agent that participates in transactions involving the sale of our common shares against certain liabilities, including liabilities arising under the Securities Act.

TABLE OF CONTENTS
As of the date of this prospectus, we are not a party to any agreement, arrangement or understanding between any broker or dealer and us with respect to the offer or sale of the securities pursuant to this prospectus.
At the time that any particular offering of securities is made, to the extent required by the Securities Act, a prospectus supplement will be distributed, setting forth the terms of the offering, including the aggregate number of securities being offered, the purchase price of the securities, the initial offering price of the securities, the names of any underwriters, dealers or agents, any discounts, commissions and other items constituting compensation from us and any discounts, commissions or concessions allowed or re-allowed or paid to dealers.

However, an underwriter, in its sole discretion, may release any of the securities subject to these lock-up agreements at any time without notice. We expect an underwriter to exclude from these lock-up agreements securities exercised and/or sold pursuant to trading plans entered into by any selling shareholder pursuant to Rule 10b5-1 under the Exchange Act, that are in place at the time of an offering pursuant to this prospectus and any applicable prospectus supplement hereto that provide for periodic sales of the selling shareholders’ securities on the basis of parameters described in such trading plans.
Underwriters or agents could make sales in privately negotiated transactions and/or any other method permitted by law, including sales deemed to be an at-the-market offering as defined in Rule 415 promulgated under the Securities Act, which includes sales made directly on or through the NYSE, the existing trading market for our common shares, or sales made to or through a market maker other than on an exchange.
We will bear costs relating to the securities offered and sold by us under this Registration Statement.

DESCRIPTION OF DEBT SECURITIES
We may offer and issue debt securities from time to time in one or more series, under one or more indentures, each dated as of a date on or prior to the issuance of the debt securities to which it relates, and pursuant to an applicable prospectus supplement. We may issue senior debt securities and subordinated debt securities pursuant to separate indentures, a senior indenture and a subordinated indenture, respectively, in each case between us and the trustee named in the indenture. We have filed forms of these documents as exhibits to the registration statement, of which this prospectus forms a part. The senior indenture and the subordinated indenture, as amended or supplemented from time to time, are sometimes referred to individually as an “indenture” and collectively as the “indentures.” Each indenture will be subject to and governed by the Trust Indenture Act and will be construed in accordance with and governed by the laws of the State of New York, without giving effect to any principles thereof relating to conflicts of law that would result in the application of the laws of any other jurisdiction, unless otherwise stated in the applicable prospectus supplement and indenture (or post-effective amendment hereto). The aggregate principal amount of debt securities which may be issued under each indenture will contain the specific terms of any series of debt securities or provide that those terms must be set forth in or determined pursuant to, an authorizing resolution, as defined in the applicable prospectus supplement, and/or a supplemental indenture, if any, relating to such series. Our debt securities may be convertible or exchangeable into any of our equity or other debt securities.
The following description sets forth certain general terms and provisions of the debt securities. The particular terms and provisions of the debt securities offered by any prospectus supplement, and the extent to which the general terms and provisions described below may apply to the offered debt securities, will be described in the applicable subsequent filings. We refer to any applicable prospectus supplement, amendment to the registration statement of which this prospectus forms a part, and reports we file with the Commission under the Exchange Act as “subsequent filings.” The statements below are not complete and are subject to, and are qualified in their entirety by reference to, all of the provisions of the applicable indenture. The specific terms of any debt securities that we may offer, including any modifications of, or additions to, the general terms described below as well as any applicable material U.S. federal income tax considerations concerning the ownership of such debt securities will be described in the applicable prospectus supplement and indenture and, as applicable, supplemental indenture. Accordingly, for a complete description of the terms of a particular issue of debt securities, the general description of the debt securities set forth below should be read in conjunction with the applicable prospectus supplement and indenture, as amended or supplemented from time to time.
General
We expect that neither indenture will limit the amount of debt securities which may be issued. The debt securities may be issued in one or more series.
You should read the applicable indenture and subsequent filings relating to the particular series of debt securities for the following terms of the offered debt securities:

the designation, aggregate principal amount and authorized denominations;

the issue price, expressed as a percentage of the aggregate principal amount;

the maturity date;

the interest rate per annum, if any;

if the debt securities provide for interest payments, the date from which interest will accrue, the dates on which interest will be payable, the date on which payment of interest will commence and the regular record dates for interest payment dates;

any optional or mandatory sinking fund provisions or exchangeability provisions;

the terms and conditions upon which conversion of any convertible debt securities may be effected, including the conversion price, the conversion period and other conversion provisions;

whether the debt securities will be our senior or subordinated securities;
13

TABLE OF CONTENTS

the date, if any, after which and the price or prices at which the debt securities may be optionally redeemed or must be mandatorily redeemed and any other terms and provisions of optional or mandatory redemptions;

if other than denominations of  $1,000 and any integral multiple thereof, the denominations in which the debt securities of the series will be issuable;

if other than the full principal amount, the portion of the principal amount of the debt securities of the series which will be payable upon acceleration or provable in bankruptcy;

any events of default not set forth in this prospectus;

the currency or currencies, including composite currencies, in which principal, premium and interest will be payable, if other than the currency of the United States of America;

if principal, premium or interest is payable, at our election or at the election of any holder, in a currency other than that in which the debt securities of the series are stated to be payable, the period or periods within which, and the terms and conditions upon which, the election may be made;

whether interest will be payable in cash or additional securities at our or the holder’s option and the terms and conditions upon which the election may be made;

if denominated in a currency or currencies other than the currency of the United States of America, the equivalent price in the currency of the United States of America for purposes of determining the voting rights of holders of those debt securities under the applicable indenture;

if the amount of payments of principal, premium or interest may be determined with reference to an index, formula or other method based on a coin or currency other than that in which the debt securities of the series are stated to be payable, the manner in which the amounts will be determined;

whether the debt securities will be issued in the form of global securities or certificates in registered form;

any other special features of the debt securities.
Subsequent filings may include additional terms not listed above. Unless otherwise indicated in subsequent filings with the Commission relating to the indenture, principal, premium and interest will be payable and the debt securities will be transferable at the corporate trust office of the applicable trustee. Unless other arrangements are made or set forth in subsequent filings or a supplemental indenture, principal, premium and interest will be paid by checks mailed to the registered holders at their registered addresses.
Unless otherwise indicated in subsequent filings with the Commission, the debt securities will be issued only in fully registered form without coupons, in denominations of  $1,000 or any integral multiple thereof. No service charge will be made for any transfer or exchange of the debt securities, but we may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection with these debt securities.
14

TABLE OF CONTENTS
Some or all of the debt securities may be issued as discounted debt securities, bearing no interest or interest at a rate which at the time of issuance is below market rates, to be sold at a substantial discount below the stated principal amount. United States federal income tax consequences and other special considerations applicable to any discounted securities will be described in subsequent filings with the Commission relating to those securities.
Senior Debt
We may issue senior debt securities, which may be secured or unsecured, under the senior debt indenture. The senior debt securities will rank on an equal basis with all our other senior debt except subordinated debt. The senior debt securities will be effectively subordinated, however, to all of our secured debt to the extent of the value of the collateral securing such debt. We will disclose the amount of our debt in the prospectus supplement.
Subordinated Debt
We may issue subordinated debt securities under a subordinated debt indenture. Subordinated debt would rank subordinate and junior in right of payment, to the extent set forth in the subordinated debt indenture, to all our senior debt.
Covenants
Any series of debt securities may have covenants in addition to or differing from those included in the applicable indenture which will be described in subsequent filings prepared in connection with the offering of such securities, limiting or restricting, among other things:

our ability to incur either secured or unsecured debt, or both;

our ability to make certain payments, dividends, redemptions or repurchases;

our ability to create dividend and other payment restrictions affecting our subsidiaries;

our ability to make investments;

mergers and consolidations by us or our subsidiaries;

sales of assets by us;

our ability to enter into transactions with affiliates;

our ability to incur liens; and

sale and leaseback transactions.
Modification of the Indentures
We expect that each indenture and the rights of the respective holders may be modified by us only with the consent of holders of not less than a majority in aggregate principal amount of the outstanding debt securities of all series under the respective indenture affected by the modification, taken together as a class. But we expect that no modification that:
(1)
changes the amount of securities whose holders must consent to an amendment, supplement or waiver;
(2)
reduces the rate of or changes the interest payment time on any security or alters its redemption provisions (other than any alteration to any such section which would not materially adversely affect the legal rights of any holder under the indenture) or the price at which we are required to offer to purchase the securities;
(3)
reduces the principal or changes the maturity of any security or reduces the amount of, or postpones the date fixed for, the payment of any sinking fund or analogous obligation;
15

TABLE OF CONTENTS
(4)
waives a default or event of default in the payment of the principal of or interest, if any, on any security (except a rescission of acceleration of the securities of any series by the holders of at least a majority in principal amount of the outstanding securities of that series and a waiver of the payment default that resulted from such acceleration);
(5)
makes the principal of or interest, if any, on any security payable in any currency other than that stated in the security;
(6)
makes any change with respect to holders’ rights to receive principal and interest, the terms pursuant to which defaults can be waived, certain modifications affecting shareholders or certain currency-related issues; or
(7)
waives a redemption payment with respect to any security or changes any of the provisions with respect to the redemption of any securities;
will be effective against any holder without his consent. Other terms as specified in subsequent filings may be modified without the consent of the holders.
Events of Default
We expect that each indenture will define an event of default for the debt securities of any series as being any one of the following events:

default in any payment of interest when due which continues for 30 days;

default in any payment of principal or premium at maturity;

default in the deposit of any sinking fund payment when due;

default in the performance of any covenant in the debt securities or the applicable indenture which continues for 60 days after we receive notice of the default;

default under a bond, debenture, note or other evidence of indebtedness for borrowed money by us or our subsidiaries (to the extent we are directly responsible or liable therefor) having a principal amount in excess of a minimum amount set forth in the applicable subsequent filings, whether such indebtedness now exists or is hereafter created, which default shall have resulted in such indebtedness becoming or being declared due and payable prior to the date on which it would otherwise have become due and payable, without such acceleration having been rescinded or annulled or cured within 30 days after we receive notice of the default; and

events of bankruptcy, insolvency or reorganization.
An event of default of one series of debt securities will not necessarily constitute an event of default with respect to any other series of debt securities.
There may be such other or different events of default as described in an applicable subsequent filings with respect to any class or series of debt securities.
We expect that under each indenture, in case an event of default occurs and continues for the debt securities of any series, the applicable trustee or the holders of not less than 25% in aggregate principal amount of the debt securities then outstanding of that series may declare the principal and accrued but unpaid interest of the debt securities of that series to be due and payable. Further, any event of default for the debt securities of any series which has been cured is expected to be permitted to be waived by the holders of a majority in aggregate principal amount of the debt securities of that series then outstanding.
We expect that each indenture will require us to file annually after debt securities are issued under that indenture with the applicable trustee a written statement signed by two of our officers as to the absence of material defaults under the terms of that indenture. We also expect that each indenture will provide that the applicable trustee may withhold notice to the holders of any default if it considers it in the interest of the holders to do so, except notice of a default in payment of principal, premium or interest.
16

TABLE OF CONTENTS
Subject to the duties of the trustee in case an event of default occurs and continues, we expect that each indenture will provide that the trustee is under no obligation to exercise any of its rights or powers under that indenture at the request, order or direction of holders unless the holders have offered to the trustee reasonable indemnity. Subject to these provisions for indemnification and the rights of the trustee, each indenture is expected to provide that the holders of a majority in principal amount of the debt securities of any series then outstanding have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee as long as the exercise of that right does not conflict with any law or the indenture.
Defeasance and Discharge
The terms of each indenture are expected to provide us with the option to be discharged from any and all obligations in respect of the debt securities issued thereunder upon the deposit with the trustee, in trust, of money or U.S. government obligations, or both, which through the payment of interest and principal in accordance with their terms will provide money in an amount sufficient to pay any installment of principal, premium and interest on, and any mandatory sinking fund payments in respect of, the debt securities on the stated maturity of the payments in accordance with the terms of the debt securities and the indenture governing the debt securities. We expect that this right may only be exercised if, among other things, we have received from, or there has been published by, the United States Internal Revenue Service a ruling to the effect that such a discharge will not be deemed, or result in, a taxable event with respect to holders. This discharge would not apply to our obligations to register the transfer or exchange of debt securities, to replace stolen, lost or mutilated debt securities, to maintain paying agencies and hold moneys for payment in trust.
Defeasance of Certain Covenants
We expect that the terms of the debt securities provide us with the right not to comply with specified covenants and that specified events of default described in a subsequent filing will not apply provided we deposit with the trustee money or U.S. government obligations, or both, which through the payment of interest and principal will provide money in an amount sufficient to pay any installment of principal, premium, and interest on, and any mandatory sinking fund payments in respect of, the debt securities on the stated maturity of such payments in accordance with the terms of the debt securities and the indenture governing such debt securities. We expect that to exercise this right, we will also be required to deliver to the trustee an opinion of counsel to the effect that the deposit and related covenant defeasance should not cause the holders of such series to recognize income, gain or loss for federal income tax purposes.
We refer you to applicable subsequent filings with respect to any deletions or additions or modifications from the description contained in this prospectus.

DESCRIPTION OF WARRANTS
We may issue warrants to purchase any of our debt or equity securities or securities of third parties or other rights, including rights to receive payment in cash or securities based on the value, rate or price of one or more specified commodities, currencies, securities or indices, or any combination of the foregoing. Warrants may be issued independently or together with any other securities and may be attached to, or separate from, such securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a warrant agent. The terms of any warrants to be issued and a description of the material provisions of the applicable warrant agreement will be set forth in the applicable prospectus supplement.
The warrants will be construed in accordance with and governed by the laws of the State of New York, without giving effect to any principles thereof relating to conflicts of law that would result in the application of the laws of any other jurisdiction, unless otherwise stated in the applicable prospectus supplement (or a post-effective amendment hereto).

TABLE OF CONTENTS
DESCRIPTION OF PURCHASE CONTRACTS
We may issue purchase contracts for the purchase or sale of any of our debt or equity securities issued by us.
Each purchase contract will entitle the holder thereof to purchase or sell, and obligate us to sell or purchase, on specified dates, such securities at a specified purchase price, which may be based on a formula, all as set forth in the applicable prospectus supplement. We may, however, satisfy our obligations, if any, with respect to any purchase contract by delivering the cash value of such purchase contract or the cash value of the security otherwise deliverable, as set forth in the applicable prospectus supplement. The applicable prospectus supplement will also specify the methods by which the holders may purchase or sell such securities, and any acceleration, cancellation or termination provisions, provisions relating to U.S. federal income tax considerations, if any, or other provisions relating to the settlement of a purchase contract.
The purchase contracts may require us to make periodic payments to the holders thereof or vice versa, which payments may be deferred to the extent set forth in the applicable prospectus supplement, and those payments may be unsecured or pre-funded on some basis. The purchase contracts may require the holders thereof to secure their obligations in a specified manner to be described in the applicable prospectus supplement. Alternatively, purchase contracts may require holders to satisfy their obligations thereunder when the purchase contracts are issued. Our obligation to settle such pre-paid purchase contracts on the relevant settlement date may constitute indebtedness. Accordingly, pre-paid purchase contracts will be issued under an indenture.
The purchase contracts will be construed in accordance with and governed by the laws of the State of New York, without giving effect to any principles thereof relating to conflicts of law that would result in the application of the laws of any other jurisdiction, unless otherwise stated in the applicable prospectus supplement (or a post-effective amendment hereto).

DESCRIPTION OF RIGHTS
We may issue rights to purchase our equity securities. These rights may be issued independently or together with any other security offered by this prospectus and may or may not be transferable by the shareholder receiving the rights in the rights offering. In connection with any rights offering, we may enter into a standby underwriting agreement with one or more underwriters pursuant to which the underwriter will purchase any securities that remain unsubscribed for upon completion of the rights offering.
The applicable prospectus supplement relating to any rights will describe the terms of the offered rights. The description in the applicable prospectus supplement of any rights we offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable rights certificate or rights agreement, which will be filed with the Commission if we offer rights. For more information on how you can obtain copies of any rights certificate or rights agreement if we offer rights, see “Where You Can Find Additional Information” of this prospectus. We urge you to read the applicable rights certificate, the applicable rights agreement and any applicable prospectus supplement in their entirety.
The rights will be construed in accordance with and governed by the laws of the State of New York, without giving effect to any principles thereof relating to conflicts of law that would result in the application of the laws of any other jurisdiction, unless otherwise stated in the applicable prospectus supplement (or a post-effective amendment hereto).
