    Secured Debt
    Each of our secured credit facilities contains financial and restrictive covenants, which require us to, among other things, comply with certain financial tests (described below); deliver quarterly and annual financial statements and annual projections, and restrictive covenants, including maintain adequate insurances; comply with laws (including environmental laws and ERISA); and maintain flag and class of our vessels. Other such covenants may, among other things, restrict consolidations, mergers or sales of our assets; require us to obtain lender approval on changes in our vessel manager; limit our ability to place liens on our assets; limit our ability to incur additional indebtedness; prohibit us from paying dividends if there is a covenant breach under the loan or an event of default has occurred or would occur as a result of payment of such dividend; prohibit our transactions with affiliates. Furthermore, our debt agreements contain cross-default provisions that may be triggered if we default under the terms of any one of our financing agreements.
    These secured credit facilities may be secured by, among other things:
    a first priority mortgage over the relevant collateralized vessels;
    a first priority assignment of earnings, insurances and charters from the mortgaged vessels for the specific facility;
    a pledge of earnings generated by the mortgaged vessels for the specific facility; and
    a pledge of the equity interests of each vessel owning subsidiary under the specific facility.
    Minimum interest coverage ratio amendment
    In July and August 2017, we amended the ratio of EBITDA to net interest expense ratio financial covenant on our secured credit facilities (wherever applicable) for the quarters ended June 30, 2017, September 30, 2017, December 31, 2017 and March 31, 2018. Under this amendment, the ratio was reduced to greater than 1.50 to 1.00 from 2.50 to 1.00. In February and March 2018, the amendment was further extended until December 31, 2018. Prepayments under certain facilities were made as part of these amendments, which are described below. These amendments have been accounted for as debt modifications.
    Each of our secured credit facilities are described below.
    2011 Credit Facility
    On May 3, 2011, we executed a credit facility with Nordea Bank Finland plc, acting through its New York branch, DNB Bank ASA, acting through its New York branch, and ABN AMRO Bank N.V., for a senior secured term loan facility of up to $150.0 million. During the year ended December 31, 2017, we repaid the outstanding balance of $93.0 million, consisting of:
    $42.2 million repaid in connection with the sale and leaseback of STI Beryl, STI Le Rocher and STI Larvotto;
    $26.3 million repaid as a result of the refinancing of the amounts due for STI Sapphire and STI Emerald;
    $23.7 million repaid as a result of the refinancing of the amounts due for STI Duchessa and STI Onyx; and
    $0.8 million in scheduled repayments.
    We wrote off an aggregate of $0.1 million of deferred financing fees as a result of these transactions.

    K-Sure Credit Facility
    In February 2014, we entered into a $458.3 million senior secured term loan facility which consists of a $358.3 million tranche with a group of financial institutions that is being 95% covered by Korea Trade Insurance Corporation, or the K-Sure Tranche, and a $100.0 million commercial tranche with a group of financial institutions led by DNB Bank ASA, or the Commercial Tranche.

    In addition to KEXIM’s commitment of up to $300.6 million, KEXIM also provided an optional guarantee for a five-year amortizing note of $125.25 million, the proceeds of which reduced the $300.6 million KEXIM Tranche. These notes were issued on July 18, 2014 when Seven and Seven Ltd., an exempted company incorporated with limited liability under the laws of the Cayman Islands completed an offering of $125,250,000 in aggregate principal amount of floating rate guaranteed notes due 2019, or the KEXIM Notes, in a private offering to qualified institutional buyers pursuant to the Securities Act and in offshore transactions complying with Regulation S under the Securities Act. The KEXIM Notes were issued in connection with the KEXIM Tranche and reduced KEXIM's funding obligations and our borrowing costs under the KEXIM Tranche by 1.55% per year. Seven and Seven Ltd. is an unaffiliated company that was incorporated for the purpose of facilitating this transaction and servicing the bonds until maturity.
    Payment of 100% of all regularly scheduled installments of principal of, and interest on, the KEXIM Notes are guaranteed by KEXIM.

    The remaining availability was used to partially finance the purchase of the remaining MR product tanker that was under construction at HMD as of December 31, 2017, which was delivered in January 2018. Drawdowns are available at an amount equal to the lower of 60% of the contract price and 60% of the fair market value of each respective vessel. Other key terms are as follows:

    The second commercial tranche of $25.0 million has a final maturity of nine years from the drawdown date of each vessel (assuming KEXIM or GIEK have not exercised their option to call for prepayment of the KEXIM and GIEK funded and guaranteed tranches by the date falling two months prior to the maturity of the first commercial tranche and in the event that the first commercial tranche has not been extended), bears interest at LIBOR plus a margin of 2.25% per annum, and has a 15 year repayment profile.
    The KEXIM Funded Tranche and GIEK Guaranteed Tranche have a final maturity of 12 years from the drawdown date of each vessel (assuming the commercial tranches are refinanced through that date), bear interest at LIBOR plus a margin of 2.15% per annum, and have a 12 year repayment profile.

    Lease financing arrangements
    Lease Financing - STI Lombard
    In July 2015, we entered into an agreement with an unrelated third-party to purchase STI Lombard, an LR2 product tanker, which was under construction at DSME, for approximately $59.0 million. As part of this agreement, we agreed to make a deposit of $5.9 million and to bareboat charter-in the vessel for up to nine months, at $10,000 per day. STI Lombard was delivered to us under the bareboat charter-in agreement in August 2015. This transaction was accounted for as a finance lease as of December 31, 2015 and the finance lease liability was $53.4 million at that date. In April 2016, we took ownership of this vessel at the conclusion of the bareboat charter-in agreement and paid the remaining 90% of the purchase price, or $53.1 million, as part of this transaction. Accordingly, all amounts due under the finance lease were settled at that date.
    2017 Lease Financing Arrangements Overview
    The below lease financing arrangements were entered into during 2017 or were assumed as part of the Merger with NPTI.  For each arrangement, we have evaluated whether, in substance, these transactions are leases or merely a form of financing.  As a result of this evaluation, we have concluded that each agreement is a form of financing on the basis that the terms and conditions are such that we never part with the risks and rewards incidental to ownership of each vessel for the remainder of its useful life.  This conclusion was reached, in part, as a result of the existence within each agreement of either a purchase obligation or a purchase option that will almost certainly be exercised.  Accordingly, the liability under each arrangement has been recorded at amortized cost using the effective interest method, and the corresponding vessels have been recorded at cost, less accumulated depreciation, on our consolidated balance sheet.
    The obligations set forth below are secured by, among other things, assignments of earnings and insurances and stock pledges and account charges in respect of the subject vessels. All of the financing arrangements contain customary events of default, including cross-default provisions.
    Bank of Communications Financial Leasing MR financing, or the BCFL Lease Financing (MR)
    In September 2017, we entered into finance lease agreements to sell and lease back five 2012 built MR product tankers (STI Amber, STI Topaz, STI Ruby, STI Garnet and STI Onyx) to an unaffiliated third party for a sales price of $27.5 million per vessel. The financing for STI Topaz, STI Ruby and STI Garnet closed in September 2017. The financing for STI Onyx closed in October 2017, and the financing for STI Amber closed in November 2017. Each agreement is for a fixed term of seven years at a bareboat rate of $9,025 per vessel per day, and we have three consecutive one-year options to extend each charter beyond the initial term. Furthermore, we have the option to purchase these vessels beginning at the end of the fifth year of the agreements through the end of the tenth year of the agreements. A deposit of $5.1 million per vessel was retained by the buyers and will either be applied to the purchase price of the vessel if a purchase option is exercised, or refunded to us at the expiration of the agreement (as applicable).
    Our BCFL Lease Financing (MR) includes a financial covenant that requires us to maintain the aggregate of the fair market value of each vessel leased under the facility plus the aforementioned $5.1 million deposit shall at all times be no less than 100% of the then outstanding balance plus the aforementioned $5.1 million deposit.
    The aggregate outstanding balance under this arrangement was $109.2 million as of December 31, 2017, and we were in compliance with the financial covenants as of that date.
    Bank of Communications Financial Leasing LR2 financing, or the BCFL Lease Financing (LR2)
    In connection with the Merger, we assumed the obligations under NPTI’s finance lease arrangement with Bank of Communications Finance Leasing Co Ltd., or BCFL, for three LR2 tankers (STI Solace, STI Solidarity, and STI Stability) upon the September Closing. Under the arrangement, each vessel is subject to a 10-year bareboat charter, which charters expire in July 2026. Charterhire under the arrangement is determined in advance, on a quarterly basis and is calculated by determining the payment based off of the then outstanding balance, the time to expiration and an interest rate of LIBOR plus 3.50%. Using the forward interest swap curve at December 31, 2017, future monthly principal payments are estimated to be $0.2 million per vessel gradually increasing to $0.3 million per vessel per month until the expiration of the agreement. We have purchase options to re-acquire each of the subject vessels during the bareboat charter period, with the first of such options exercisable at the end of the fourth year from the delivery date of the respective vessel. There is also a purchase obligation for each vessel upon the expiration of the agreement for $29.7 million in aggregate.
    Additionally, we have an aggregate of $0.8 million on deposit in a deposit account as of December 31, 2017 in accordance with the terms and conditions of this facility. The funds deposited in this account are not freely available and will be released upon maturity. The balance in this account has been recorded as non-current Restricted Cash on our consolidated balance sheet as of December 31, 2017.
    The carrying value of the amounts due under this arrangement (which reflect fair value adjustments made as part of the initial purchase price allocation) was $104.2 million as of December 31, 2017, and we were in compliance with the financial covenants as of that date.
    CSSC Shipping Lease Financing
    In connection with the Merger, we assumed the obligations under NPTI’s finance lease arrangement with CSSC (Hong Kong) Shipping Company Limited, or CSSC, for eight LR2 tankers (STI Gallantry, STI Nautilus, STI Guard, STI Guide, STI Goal, STI Gauntlet, STI Gladiator and STI Gratitude) upon the September Closing. Under the arrangement, each vessel is subject to a 10-year bareboat charter which charters expire throughout 2026 and 2027 (depending on the vessel). Charterhire under the arrangement is comprised of a fixed repayment amount of $0.2 million per month per vessel plus a variable component calculated at LIBOR plus 4.60%. We have purchase options to re-acquire each of the subject vessels during the bareboat charter period, with the first of such options exercisable at the end of the fourth year from the delivery date of the respective vessel. There is also a purchase obligation for each vessel upon the expiration of the agreement for $111.4 million in aggregate.
    Our CSSC finance lease arrangement includes a financial covenant that requires the fair market value of each vessel that is leased under this facility to at all times be no less than 125% of the applicable outstanding balance for such vessel. In September 2017, we made a $10.9 million aggregate prepayment on this arrangement to maintain compliance with this covenant. This prepayment was released from restricted cash that was assumed from NPTI at the closing date of the Merger.
    The carrying value of the amounts due under this arrangement (which reflect fair value adjustments made as part of the initial purchase price allocation) was $270.0 million as of December 31, 2017, and we were in compliance with the financial covenants as of that date.
    CMBFL Lease Financing
    In connection with the Merger, we assumed the obligations under NPTI’s finance lease arrangement with CMB Financial Leasing Co. Ltd, or CMBFL, for two LR1 tankers (STI Pride and STI Providence) upon the September Closing. Under this arrangement, each vessel is subject to a seven-year bareboat charter, which expires in July or August 2023 (depending on the vessel). Charterhire under the arrangement is comprised of a fixed, quarterly repayment amount of $0.6 million per vessel plus a variable component calculated at LIBOR plus 3.75%. We have purchase options to re-acquire each of the subject vessels during the bareboat charter period, with the first of such options exercisable on the third anniversary from the delivery date of the respective vessel. There is also a purchase obligation for each vessel upon the expiration of the agreement for $40.2 million in aggregate. We are subject to certain terms and conditions, including financial covenants, under this arrangement which are summarized as follows:
    The ratio of net debt to total capitalization no greater than 0.60 to 1.00.
    Consolidated tangible net worth no less than $1.0 billion plus (i) 25% of the cumulative positive net income (on a consolidated basis) for each fiscal quarter commencing on or after January 1, 2016 and (ii) 50% of the net proceeds of new equity issues occurring on or after January 1, 2016.
    Minimum liquidity of not less than the greater of $25.0 million or $500,000 per each owned vessel and $250,000 per each time chartered-in vessel.
    The fair market value of each vessel leased under the facility shall at all times be no less than 115% of the outstanding balance for such vessel.
    Additionally, we have an aggregate of $2.0 million on deposit in a deposit account as of December 31, 2017 in accordance with the terms and conditions of this facility. The funds deposited in this account are not freely available and will be released upon maturity. The balance in this account has been recorded as non-current Restricted Cash on our consolidated balance sheet as of December 31, 2017.
    The carrying value of the amounts due under this arrangement (which reflect fair value adjustments made as part of the initial purchase price allocation) was $65.9 million as of December 31, 2017, and we were in compliance with the financial covenants as of that date.
    Ocean Yield Lease Financing
    In connection with the Merger, we assumed the obligations under NPTI’s finance lease arrangement with Ocean Yield ASA for four LR2 tankers (STI Sanctity, STI Steadfast, STI Supreme, and STI Symphony) upon the September Closing. Under this arrangement, each vessel is subject to a 13-year bareboat charter, which expires between February and August 2029 (depending on the vessel). Charterhire, which is paid monthly in advance, includes a fixed payment in addition to a quarterly adjustment based on prevailing LIBOR rates.
    Monthly principal payments are approximately $0.2 million per vessel gradually increasing to $0.3 million per vessel per month until the expiration of the agreement. The interest component of the leases approximates LIBOR plus 5.40%. We also have purchase options to re-acquire each of the vessels during the bareboat charter period, with the first of such options exercisable beginning at the end of the seventh year from the delivery date of the subject vessel.
    We are subject to certain terms and conditions, including financial covenants, under this arrangement which are summarized as follows:
    The ratio of net debt to total capitalization no greater than 0.60 to 1.00.
    Consolidated tangible net worth no less than $1.0 billion plus (i) 25% of the cumulative positive net income (on a consolidated basis) for each fiscal quarter commencing on or after January 1, 2016 and (ii) 50% of the net proceeds of new equity issues occurring on or after January 1, 2016.

The net proceeds from the issuance of the Senior Notes Due 2020 were $51.8 million after deducting the underwriters’ discounts, commissions and offering expenses.
    The Senior Notes Due 2020 bear interest at a coupon rate of 6.75% per year, payable quarterly in arrears on the 15th day of February, May, August and November of each year. Coupon payments commenced on August 15, 2014. The Senior Notes Due 2020 are redeemable at our option, in whole or in part, at any time on or after May 15, 2017 at a redemption price equal to 100% of the principal amount to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date.
    The Senior Notes Due 2020 are our senior unsecured obligations and rank equally with all of our existing and future senior unsecured and unsubordinated debt and are effectively subordinated to our existing and future secured debt, to the extent of the value of the assets securing such debt, and will be structurally subordinated to all existing and future debt and other liabilities of our subsidiaries. No sinking fund is provided for the Senior Notes Due 2020. The Senior Notes Due 2020 were issued in minimum denominations of $25.00 and integral multiples of $25.00 in excess thereof and are listed on the NYSE under the symbol “SBNA.”
    The Senior Notes Due 2020 require us to comply with certain covenants, including financial covenants; restrictions on consolidations, mergers or sales of assets and prohibitions on paying dividends or returning capital to equity holders if a covenant breach or an event of default has occurred or would occur as a result of such payment. If we undergo a change of control, holders may require us to repurchase for cash all or any portion of their notes at a change of control repurchase price equal to 101% of the principal amount of the notes to be repurchased, plus accrued and unpaid interest to, but excluding, the change of control purchase date.
    The financial covenants under our Senior Notes Due 2020 include:
    Net borrowings shall not equal or exceed 70% of total assets.
    Net worth shall always exceed $650.0 million.
    The outstanding balance was $53.75 million as of December 31, 2017 and December 31, 2016, and we were in compliance with the financial covenants relating to the Senior Notes Due 2020 as of those dates.
    Convertible Senior Notes Due 2019
    In June 2014, we issued $360.0 million in aggregate principal amount of convertible senior notes due 2019, or the Convertible Notes, in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act. This amount includes the full exercise of the initial purchasers’ option to purchase an additional $60.0 million in aggregate principal amount of the Convertible Notes in connection with the offering. The net proceeds we received from the issuance of the Convertible Notes after the exercise of the initial purchasers’ option to purchase additional Convertible Notes were $349.0 million after deducting the initial purchasers’ discounts, commissions and offering expenses of $11.0 million. As part of the transaction, we used a portion of the net proceeds to repurchase $95.0 million of our common stock, or 10,127,600 shares, at $9.38 per share in a privately negotiated transaction.
    The Convertible Notes bear interest at a coupon rate of 2.375% per annum, and are payable semi-annually in arrears on January 1 and July 1 of each year beginning on January 1, 2015. The Convertible Notes will mature on July 1, 2019, unless earlier converted, redeemed or repurchased. At issuance, the Convertible Notes were convertible in certain circumstances and during certain periods at an initial conversion rate of 82.0075 shares of common stock per $1,000 (which represents an initial conversion price of approximately $12.19 per share of common stock), subject to adjustment in certain circumstances as set forth in the indenture governing the Convertible Notes. Adjustments were made during years ended December 31, 2017 and 2016 to the initial conversion rate as a result of the issuance of dividends to our common stockholders. The table below details the dividends declared from the issuance of the Convertible Notes through December 31, 2017 and their corresponding effect to the conversion rate of the Convertible Notes. The conversion rate as of December 31, 2017 was 98.7742.

    (1)  Per $1,000 principal amount.

    Holders may convert their notes at their option at any time prior to the close of business on the business day immediately preceding January 1, 2019 only under the following circumstances:
    during any calendar quarter commencing after the calendar quarter ending on September 30, 2014 (and only during such calendar quarter), if the last reported sale price of the common stock for at least 15 trading days (whether or not consecutive) during a period of 25 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;
    during the five-business day period after any five consecutive trading day period, or the Measurement Period, in which the trading price (as defined in the indenture) per $1,000 principal amount of Convertible Notes for each trading day of the Measurement Period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate on each such trading day;
    if the Company calls any or all of the Convertible Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date; or
    upon the occurrence of specified corporate events as defined in the indenture (e.g. consolidations, mergers, a binding share exchange or the transfer or lease of all or substantially all of our assets).
    We were not permitted to redeem the Convertible Notes prior to July 6, 2017. Effective July 6, 2017, we may redeem for cash all or any portion of the notes, at our option if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for at least 15 trading days (whether or not consecutive) during any 25 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. No sinking fund is provided for the Convertible Notes.
    The Convertible Notes require us to comply with certain covenants such as restrictions on consolidations, mergers or sales of assets. Additionally, if we undergo a fundamental change, holders may require us to repurchase for cash all or any portion of their notes at a fundamental change repurchase price equal to 100% of the principal amount of the notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date.
    Upon issuance, we determined the initial carrying value of the liability component of the Convertible Notes to be $298.7 million based on the fair value of a similar liability that does not have any associated conversion feature. We used our Senior Notes Due 2020 issued in May 2014 as the basis for this determination. The difference between the fair value of the liability component and the face value of the Convertible Notes is being amortized over the term of the Convertible Notes under the effective interest method and recorded as part of financial expenses. The residual value of $61.3 million (the conversion feature) was recorded to Additional paid-in capital upon issuance.
    In July 2015, we repurchased $1.5 million face value of our Convertible Notes at an average price of $1,088.10 per $1,000 principal amount. As a result of this transaction, we reduced the liability and equity components of the Convertible Notes by $1.3 million and $0.4 million, respectively and we recorded a gain of $46,273, which is recorded within financial income of consolidated statement of income or loss. We also wrote off $30,880 of deferred financing fees as a result of this transaction.
    In March 2016, we repurchased $5.0 million face value of our Convertible Notes at an average price of $831.05 per $1,000 principal amount, or $4.2 million. As a result of this transaction, we reduced the liability and equity components of the Convertible Notes by $4.4 million and $0.3 million, respectively and we recorded a gain of $0.6 million, which is recorded within financial income of the consolidated statement of income or loss. We also wrote off $0.1 million of deferred financing fees as a result of this transaction.
    In May 2016, we repurchased $5.0 million face value of our Convertible Notes at an average price of $847.50 per $1,000 principal amount, or $4.2 million. As a result of this transaction, we reduced the liability and equity components of the Convertible Notes by $4.4 million and $0.2 million, respectively and we recorded a gain of $0.4 million, which is recorded within financial income of the consolidated statement of income or loss. We also wrote off $0.1 million of deferred financing fees as a result of this transaction.
    The carrying values of the liability component of the Convertible Notes as of December 31, 2017 and 2016, were $328.7 million and $316.5 million, respectively. We incurred $8.3 million of coupon interest and $12.2 million of non-cash accretion of our Convertible Notes during the year ended December 31, 2017. We incurred $8.3 million of coupon interest and $11.6 million of non-cash accretion of our Convertible Notes during the year ended December 31, 2016.
    We were in compliance with the covenants related to the Convertible Notes as of December 31, 2017 and December 31, 2016.

    In March 2017, we initiated a cash tender offer for our Senior Notes due 2017, which commenced simultaneously with the offering of the Senior Notes due 2019 (described below) and expired in April 2017. A total of $6.3 million aggregate principal amount of our Senior Notes due 2017 was tendered as part of this process and settled in April 2017.

No sinking fund is provided for the Senior Notes Due 2019. The Senior Notes Due 2019 were issued in minimum denominations of $25.00 and integral multiples of $25.00 in excess thereof and are listed on the NYSE under the symbol SBBC.
    The Senior Notes Due 2019 require us to comply with certain covenants, including financial covenants; restrictions on consolidations, mergers or sales of assets and prohibitions on paying dividends or returning capital to equity holders if a covenant breach or an event of default has occurred or would occur as a result of such payment.
