We entered into interest rate swap and swaption agreements to mitigate our interest rate risk from our floating-rate debt, and for the obligations related to capital leases and associated restricted cash which were terminated in 2014.debt. We also have entered into an agreement with Teekay Corporation relating to the Toledo Spirit time-charter contract under which Teekay Corporation payspaid us any amounts payable to the charterer as a result of spot rates being below the fixed rate, and we paypaid Teekay Corporation any amounts payable to us as a result of spot rates being in excess of the fixed rate. The Toledo Spirit was sold in early 2019, and as a result, the derivative agreement ended at that time. With the exception of the interest rate swaps in our consolidated joint venture, Teekay Nakilat Corporation (or the TeekayNakilat Joint Venture), and for several interest rate swaps in certain of our equity-accounted joint ventures where we have applied hedge accounting, changes in the fair value of our derivatives are recognized immediately into income and are presented as realized and unrealized lossgain (loss) on derivative instruments in the consolidated statements of income. Please see “Item 18 – Financial Statements: Note 1213 – Derivative Instruments and Hedging Activities.”

Under GAAP, all foreign currency-denominated monetary assets and liabilities, such as cash and cash equivalents, accounts receivable, restricted cash, accounts payable, accrued liabilities, advances from affiliates and long-term debt, are revalued and reported based on the prevailing exchange rate at the end of the period. Foreign exchange gains and losses include realized and unrealized gains and losses on our cross-currencycross currency swaps. We entered into cross-currencycross currency swaps concurrently with the issuance of our Norwegian Kroner-denominatedKroner (or NOK), denominated bonds to economically hedge the foreign currency exposure on the payment of interest and principal of our NOK-denominated bonds. Our primary sources of foreign currency exchange gains and losses are our Euro-denominated term loans and NOK-denominated bonds. Euro-denominated term loans totaled, 169.0 million Euros ($193.8 million) at December 31, 2018, 194.1 million Euros ($233.0 million) at December 31, 2017, 208.9 million Euros ($219.7 million) at December 31, 2016, 227.7 million Euros ($241.8 million) at December 31, 2015 and 235.6 million Euros ($285.0 million) at December 31, 2014 and 247.6 million Euros2014. Our NOK-denominated bonds totaled 3.1 billion NOK ($340.2353.0 million) at December 31, 2013. Our NOK-denominated bonds totaled2018, 3.1 billion NOK ($377.9 million) at December 31, 2017, 3.53.2 billion NOK ($371.3 million) at December 31, 2016, 2.6 billion NOK ($294.0 million) at December 31, 2015 and 1.6 billion NOK ($214.7 million) at December 31, 2014 and 1.6 billion NOK ($263.5 million) at December 31, 2013.2014.
(5)Other (expense) income for the year ended December 31, 2018 includes a $53.0 million expense relating to the Teekay Nakilat Joint Venture recognizing an additional tax indemnification liability. Please see "Item 5 – Operating and Financial Review and Prospects: Significant Developments in 2018 and Early 2019 – Teekay Nakilat Capital Lease."
(6)Vessels and equipment consist of (a) our vessels, at cost less accumulated depreciation, (b) vessels related to capital leases, at cost less accumulated depreciation and (c) advances on our newbuildings.
(6)(7)Certain of our external charters have been accounted for as direct financing leases. As a result, the vessels associated with the external charters accounted for as direct financing leases are not included as part of vessels and equipment. Please see "Item 18 – Financial Statements: Note 56LeasesRevenue – Net Investments in Direct Financing Leases."
(7)(8)Net voyage revenues is a non-GAAP financial measure. Consistent with general practice in the shipping industry, we use net voyage revenues (defined as voyage revenues less voyage expenses) as a measure of equating revenues generated from voyage charters to revenues generated from time-charters, which assists us in making operating decisions about the deployment of our vessels and their performance. Under time-charters the charterer pays the voyage expenses, whereas under voyage charter contracts the ship owner pays these expenses. Some voyage expenses are fixed, and the remainder can be estimated. If we, as the ship owner, pay the voyage expenses, we typically pass the approximate amount of these expenses on to our customers by charging higher rates under the contract or billing the expenses to them. As a result, although voyage revenues from different types of contracts may vary, the net voyage revenues are comparable across the different types of contracts. We principally use net voyage revenues because it provides more meaningful information to us than voyage revenues, the most directly comparable GAAP financial measure. Net voyage revenues are also widely used by investors and analysts in the shipping industry for comparing financial performance between companies and to industry averages. The following table reconciles net voyage revenues with voyage revenues.revenues:

(8)(9)EBITDA and Adjusted EBITDA are non-GAAP financial measures. EBITDA represents net income before interest, taxes, depreciation and amortization. Adjusted EBITDA represents EBITDA before restructuring charges, netwrite-down of reimbursement,goodwill and write-down and loss on salesales of vessels, foreign currency exchange (gain) loss, amortization of in-process contracts included in voyage revenues net of offsetting vessel operating expenses, unrealized (gain) loss on non-designated derivative instruments, realized loss on interest rate swaps and Adjustments to Equity Income.Equity-Accounted EBITDA. EBITDA and Adjusted EBITDA are used as a supplemental financial performance measure by management and by external users of our financial statements, such as investors. EBITDA and Adjusted EBITDA assist our management and security holders by increasing the comparability of our fundamental performance from period to period and against the fundamental performance of other companies in our industry that provide EBITDA and Adjusted EBITDA information. This increased comparability is achieved by excluding the potentially disparate effects between periods or companies of interest expense, taxes, depreciation or amortization, amortization of in-process revenue contracts and realized and unrealized loss on derivative instruments relating to interest rate swaps, interest rate swaptions, and cross currency swaps, which items are affected by various and possibly changing financing methods, capital structure and historical cost basis and which items may significantly affect net income between periods. We believe that including EBITDA and Adjusted EBITDA benefits investors in (a) selecting between investing in us and other investment alternatives and (b) monitoring our ongoing financial and operational strength and health in assessing whether to continue to hold our equity or debt securities, as discussed below:applicable.
Financial and operating performance. EBITDA and Adjusted EBITDA assist our management and investors by increasing the comparability of our fundamental performance from period to period and against the fundamental performance of other companies in our industry that provide EBITDA and Adjusted EBITDA information. This increased comparability is achieved by excluding the potentially disparate effects between periods or companies of interest expense, taxes, depreciation or amortization, amortization of in-process revenue contracts and realized and unrealized loss on derivative instruments relating to interest rate swaps, interest rate swaptions, and cross-currency swaps, which items are affected by various and possibly changing financing methods, capital structure and historical cost basis and which items may significantly affect net income between periods. We believe that including EBITDA and Adjusted EBITDA as financial and operating measures benefits investors in (a) selecting between investing in us and other investment alternatives and (b) monitoring our ongoing financial and operational strength and health in assessing whether to continue to hold our common and preferred units.
Liquidity. EBITDA and Adjusted EBITDA allow us to assess the ability of assets to generate cash sufficient to service debt, pay distributions and undertake capital expenditures. By eliminating the cash flow effect resulting from our existing capitalization and other items such as dry-docking expenditures, working capital changes and foreign currency exchange gains and losses, EBITDA and Adjusted EBITDA provides a consistent measure of our ability to generate cash over the long term. Management uses this information as a significant factor in determining (a) our proper capitalization (including assessing how much debt to incur and whether changes to the capitalization should be made) and (b) whether to undertake material capital expenditures and how to finance them, all in light of our cash distribution policy. Use of EBITDA and Adjusted EBITDA as liquidity measures also permits investors to assess the fundamental ability of our business to generate cash sufficient to meet cash needs, including distributions on our common and preferred units.

Neither EBITDA nor Adjustedadjusted EBITDA should be considered as an alternative to net income, cash flow from operating activitiesincome, or any other measure of financial performance or liquidity presented in accordance with GAAP. EBITDA and Adjusted EBITDA exclude some, but not all,certain items that affect net income and income from vessel operations and these measures may vary among other companies. Therefore, EBITDA and Adjusted EBITDA as presented in this Annual Report may not be comparable to similarly titled measures of other companies.
The following table reconciles our historical consolidated EBITDA and Adjusted EBITDA to net income, the most directly comparable GAAP financial measure, and our historical consolidated Adjusted EBITDA to net operating cash flow, the most directly comparable GAAP financial measure.income.

(12)(14)Adjusted Equity-Accounted EBITDA is a non-GAAP financial measure. Adjusted Equity-Accounted EBITDA represents equity income after Adjustments to Equity Income. Adjustments to Equity Income consist of depreciation and amortization, interest expense net of interest income, income tax (recovery) expense, (recovery), amortization of in-process revenue contracts, foreign currency exchange (gain) loss, (gain), write-down and loss (gain) on sales of vessels, gain on sale of equity-accounted investment, unrealized gain on non-designated derivative instruments and realized loss on interest rate swaps, in each case related to our equity-accounted entities, on the basis of our ownership percentages of such entities. Neither Adjusted Equity-Accounted EBITDA nor Adjustments to Equity-Accounted EBITDA should be considered as an alternative to equity income or any other measure of financial performance or liquidity presented in accordance with GAAP. Adjustments to Equity-Accounted EBITDA exclude some, but not all, items that affect equity income and these measures may vary among other companies. Therefore, Adjustments to Equity-Accounted EBITDA as presented in this Annual Report may not be comparable to similarly titled measures of the other companies. When using Adjusted EBITDA as a measure of liquidity, it should be noted that this measure includes the Adjusted EBITDA


from our equity-accounted for investments. We do not have control over the operations, nor do we have any legal claim to the revenue and expenses of our equity-accounted for investments. Consequently, the cash flow generated by our equity-accounted for investments, as measured by Adjusted Equity-Accounted EBITDA, may not be available for use by us in the period generated.

RISK FACTORS
Some of the following risks relate principally to the industry in which we operate and to our business in general. Other risks relate principally to the securities market and to ownership of our common or preferred units. The occurrence of any of the events described in this section could materially and adversely affect our business, financial condition, operating results and ability to pay distributions on, and the trading price of, our common and preferred units.
We may not have sufficient cash from operations to enable us to pay distributions on our common and preferred units.
The amount of cash we can distribute on our common and preferred units principally depends upon the amount of cash we generate from our operations, which may fluctuate based on, among other things:

the rates we obtain from our charters;
the expiration of charter contracts;
the chartererscharterers' options to terminate charter contracts or repurchase vessels;
the level of our operating costs, such as the cost of crews and insurance;
the continued availability of LNG and LPG production, liquefaction and regasification facilities;
the number of unscheduled off-hire days for our fleet and the timing of, and number of days required for, scheduled dry docking of our vessels;
delays in the delivery of newbuildings and the beginning of payments under charters relating to those vessels;
prevailing global and regional economic and political conditions;
currency exchange rate fluctuations;
the effect of governmental regulations and maritime self-regulatory organization standards on the conduct of our business; and
limitation of obtaining cash distributions from joint venture entities due to similar restrictions within the joint venture entities.

The actual amount of cash we will have available for distribution also will depend on factors such as:

the level of capital expenditures we make, including for maintaining vessels, building new vessels, acquiring existing vessels and complying with regulations;
our debt service requirements and restrictions on distributions contained in our debt instruments;
fluctuations in our working capital needs;


our ability to make working capital borrowings, including to pay distributions to unitholders; and
the amount of any cash reserves, including reserves for future capital expenditures, anticipated future credit needs and other matters, established by Teekay GP L.L.C., our general partner (or our General Partner), in its discretion.

The amount of cash we generate from our operations may differ materially from our profit or loss for the period, which will be affected by non-cash items. As a result of this and the other factors mentioned above, we may make cash distributions during periods when we record losses and may not make cash distributions during periods when we record net income.
Our ability to grow may be adversely affected by our cash distribution policy.
Our cash distribution policy, which is consistent with our partnership agreement, requires us to distribute each quarter all of our Available Cash (as defined in our partnership agreement, which takes into account cash reserves for, among other things, future capital expenditures and credit needs). Accordingly, our growth may not be as fast as businesses that reinvest their Available Cash to expand ongoing operations.

In determining the amount of cash available for distribution, the boardBoard of directorsDirectors of our General Partner, in makingwhich makes the determination on our behalf, approves the amount of cash reserves to set aside, including reserves for future maintenance capital expenditures, anticipated future credit needs, working capital and other matters. We also rely upon external financing sources, including commercial borrowings and proceeds from debt and equity offerings, to fund our capital expenditures. Accordingly, to the extent we do not have sufficient cash reserves or are unable to obtain financing, our cash distribution policy may significantly impair our ability to meet our financial needs or to grow.

GlobalAlthough global crude oil prices have significantly declinedexperienced moderate recovery since mid-2014.falling from the highs reached in mid-2014, prices have not returned to those same highs. The significant decline in oil prices has also contributed to depressed natural gas prices. Lower oil prices may negatively affect both the competitiveness of natural gas as a fuel for power generation and the market price of natural gas, to the extent that natural gas prices are benchmarked to the price of crude oil. These declines in energy prices, combined with other factors beyond our control, have adversely affected energy and master limited partnership capital markets and available sources of financing for our capital expenditures and debt repayment obligations. As a result, effective forOn November 13, 2018, our General Partner announced that quarterly common unit distributions would increase by


36 percent to $0.19 per unit, commencing with the quarterly distribution for the fourthfirst quarter of 2015, we reduced2019 distribution to be paid in May 2019 as part of a balanced capital allocation strategy, however, our quarterly cash distributions per common unitdistribution policy is subject to $0.14 from $0.70,certain restrictions and our near-term business strategy is primarily to focus on funding and implementing existing growth projects and repaying or refinancing scheduled debt obligations with cash flows from operations rather than pursuing additional growth projects. It is uncertain when, if at all,may be changed by the boardBoard of directorsDirectors of our General Partner may increase quarterly cash distributions on our common units.Partner.
Our ability to repay or refinance our debt obligations and to fund our capital expenditures will depend on certain financial, business and other factors, many of which are beyond our control. To the extent we are ableunable to finance these obligations and expenditures with cash from operations or by issuing debt or equity securities, our ability to make cash distributions may be diminished or our financial leverage may increase, or our unitholders may be diluted. Our business may be adversely affected if we need to access other sources of funding.
To fund our existing and future debt obligations and capital expenditures, including our LNG and LPG carrier newbuildings, we will be required to use cash from operations, incur borrowings, and/or seek to access other financing sources. Our access to potential funding sources and our future financial and operating performance will be affected by prevailing economic conditions and financial, business, regulatory and other factors, many of which are beyond our control. If we are unable to access additional bank financing and generate sufficient cash flow to meet our debt, capital expenditure and other business requirements, we may be forced to take actions such as:

restructuring our debt;
seeking additional debt or equity capital;
selling assets;
further reducing distributions;
reducing, delaying or cancelling our business activities, acquisitions, investments or capital expenditures; or
seeking bankruptcy protection.

Such measures might not be successful, available on acceptable terms or enable us to meet our debt, capital expenditure and other obligations. Some of such measures may adversely affect our business and reputation. In addition, our financing agreements may restrict our ability to implement some of these measures.

Use of cash from operations and possible future sale of certain assets will reduce cash available for distribution to unitholders. Our ability to obtain bank financing or to access the capital markets for future offerings may be limited by our financial condition at the time of any such financing or offering as well as by adverse market conditions. Even if we are successful in obtaining necessary funds, the terms of such financings could limit our ability to pay cash distributions to unitholders or operate our business as currently conducted. In addition, incurring additional debt may significantly increase our interest expense and financial leverage, and issuing additional equity securities may result in significant unitholder dilution and would increase the aggregate amount of cash required to maintain our quarterly distributions to unitholders.
We have limited current liquidity.


As at December 31, 2017, we had total liquidity of $433.6 million, consisting of $244.2 million of cash and cash equivalents and $189.4 million of undrawn borrowings under our revolving credit facilities, subject to limitations in the credit facilities.  Our primary near-term liquidity needs include payment of our quarterly distributions, including distributions on our common and preferred units, operating expenses, dry-docking expenditures, debt service costs, scheduled repayments of long-term debt, committed capital expenditures (including, among others, installment payments for our newbuilding vessels), and the funding of general working capital requirements. We expect to manage our near-term liquidity needs from cash flows from operations, proceeds from new debt financings and refinancings, proceeds from equity offerings, and any dividends or other distributions from our equity-accounted joint ventures; however, there can be no assurance that any such funding will be available to us on acceptable terms, if at all. We do not have control over the operations, nor do we have any legal claim to the revenue and expenses of our equity-accounted joint ventures. Consequently, the cash flow generated by our equity-accounted joint ventures may not be available for use by us in the period generated.
We make substantial capital expenditures to maintain the operating capacity of our fleet, which reduce our cash available for distribution. In addition, each quarter our General Partner is required to deduct estimated maintenance capital expenditures from operating surplus, which may result in less cash available for distribution to unitholders than if actual maintenance capital expenditures were deducted.
We must make substantial capital expenditures to maintain, over the long term, the operating capacity of our fleet. These maintenance capital expenditures include capital expenditures associated with dry docking a vessel, modifying an existing vessel or acquiring a new vessel to the extent these expenditures are incurred to maintain the operating capacity of our fleet. These expenditures could increase as a result of changes in:

the cost of labor and materials;
customer requirements;
increases in the size of our fleet;
governmental regulations and maritime self-regulatory organization standards relating to safety, security or the environment; and
competitive standards.

In addition, our actual maintenance capital expenditures vary significantly from quarter to quarterquarter-to-quarter based on, among other things, the number of vessels dry docked during that quarter. Certain repair and maintenance items are more efficient to complete while a vessel is in dry dock. Consequently, maintenance capital expenditures will typically increase in periods when there is an increase in the number of vessels dry docked. Our significant maintenance capital expenditures reduce the amount of cash we have available for distribution to our unitholders.

Our partnership agreement requires our General Partner to deduct estimated, rather than actual, maintenance capital expenditures from operating surplus (as defined in our partnership agreement) each quarter in an effort to reduce fluctuations in operating surplus. The amount of estimated maintenance capital expenditures deducted from operating surplus is subject to review and change by the conflicts committee of our General Partner’s boardBoard of directorsDirectors at least once a year. In years when estimated maintenance capital expenditures are higher than actual maintenance capital expenditures – as we expect will be the case in the years we are not required to make expenditures for mandatory dry dockings – the amount of cash available for distribution to unitholders will be lower than if actual maintenance capital expenditures were


deducted from operating surplus. If our General Partner underestimates the appropriate level of estimated maintenance capital expenditures, we may have less cash available for distribution in future periods when actual capital expenditures begin to exceed our previous estimates.
We will be required to make substantial capital expenditures to expand the size of our fleet or gas business and generally are required to make significant installment payments for acquisitions of newbuilding vessels or for construction of receiving and regasification terminals prior to their delivery or completion and generation of revenue.
We make substantial capital expenditures to increase the size of our fleet or gas business. Please read “Item 5 – Operating and Financial Review and Prospects,” for additional information about our newbuilding acquisitions. As at December 31, 2017,2018, we had 15six LNG carrier newbuildings scheduled for delivery between 2018 and 2020, three LPG carrier newbuildings scheduled for delivery during 20182019, and one LNG receiving and regasification terminal under construction scheduled for completion in 2019. The obligations of us and our equity-accounted joint ventures to purchase the newbuilding vessels is not conditional upon our or their ability to obtain financing for such purchases. As at December 31, 2017,In January 2019, we have $1.7 billionhad $636 million of financing (includingin place, including the sale-leaseback financing completed on the Yamal Spirit in January 2019 and our proportionate share of financings in our equity-accounted joint ventures) in placeventures, against $652 million related to our proportionate share of the estimated remaining cost for the majority of our remaining newbuilding vessels and our LNG receiving and regasification terminal under construction and are seeking financing for two newbuilding vessels, pleaseas of December 31, 2018. Please read "Item 5 – Contractual Obligations and Contingencies." Although we believe we will obtain financing
Our substantial capital expenditures may reduce our cash available for our two remaining unfinanced newbuildings during 2018, there is no assurance that we will do so.
In additiondistribution to our newbuilding vessels, weunitholders. Funding of any capital expenditures with debt may also be obligatedsignificantly increase our interest expense and financial leverage, and funding of capital expenditures by issuing additional equity securities may result in significant unitholder dilution. Our failure to purchase oneobtain the funds for necessary future capital expenditures could have a material adverse effect on our business, results of operations and financial condition and on our leased Suezmax tankers, the Toledo Spirit, upon the charterer’s option, which may occur in 2018 and have an aggregate purchase price of approximately $26.3 million at December 31, 2017.ability to make cash distributions to unitholders.

We and Teekay Corporation regularly evaluate and pursue opportunities to provide the marine transportation requirements for new or expanding LNG and LPG projects. The award process relating to LNG transportation opportunities typically involves various stages and takes several months to complete. Neither we nor Teekay Corporation may be awarded charters relating to any of the projects we or it pursues. If any LNG project charters are awarded to Teekay Corporation, it must offer them to us pursuant to the terms of an omnibus agreement entered into in connection with our initial public offering. If we elect pursuant to the omnibus agreement to obtain Teekay Corporation’s interests in any projects


Teekay Corporation may be awarded, or if we bid on and are awarded contracts relating to any LNG and LPG project, we will need to incur significant capital expenditures to buy Teekay Corporation’s interest in these LNG and LPG projects or to build the LNG and LPG carriers.
Our substantial capital expenditures may reduce our cash available for distribution to our unitholders. Funding of any capital expenditures with debt may significantly increase our interest expense and financial leverage, and funding of capital expenditures through issuing additional equity securities may result in significant unitholder dilution. Our failure to obtain the funds for necessary future capital expenditures could have a material adverse effect on our business, results of operations and financial condition and on our ability to make cash distributions to unitholders.
A shipowner is typically required to expend substantial sums as progress payments during construction of a newbuilding, but does not derive any income from the vessel until after its delivery. If we were unable to obtain financing required to complete payments on any existing or future newbuilding orders, we could effectively forfeit all or a portion of the progress payments previously made. If we finance these payments by issuing debt or equity securities, we will increase the aggregate amount of interest or cash required to maintain our current level of quarterly distributions to unitholders prior to generating cash from the operation of the newbuilding.

To fund the remaining portion of existing or future capital expenditures, we will be required to use cash from operations or incur borrowings or raise capital through the sale of debt or additional equity securities. Use of cash from operations will reduce cash available for distributions to unitholders. Our ability to obtain bank financing or to access the capital markets for future offerings may be limited by our financial condition at the time of any such financing or offering as well as by adverse market conditions resulting from, among other things, general economic conditions and contingencies and uncertainties that are beyond our control. Our failure to obtain the funds for future capital expenditures could have a material adverse effect on our business, results of operations and financial condition and on our ability to make cash distributions. Even if we are successful in obtaining necessary funds, the terms of such financings could limit our ability to pay distributions to our unitholders. In addition, incurring additional debt may significantly increase our interest expense and financial leverage, and issuing additional equity securities may result in significant unitholder dilution and would increase the aggregate amount of cash required to maintain our current level of quarterly distributions to unitholders, which could have a material adverse effect on our ability to make cash distributions.

In addition, although delivery of the completed vessel will not occur until much later (approximately two to three years from the time the order is placed), we typically must pay an initial installment up-front upon signing the purchase contract. During the construction period, we generally are required to make installment payments on newbuildings prior to their delivery, in addition to incurring financing, miscellaneous construction and project management costs, but we do not derive any income from the vessel until after its delivery. If we finance these payments by issuing debt or equity securities, we will increase the aggregate amount of interest or cash required to maintain our current level of quarterly distributions to unitholders prior to generating cash from the operation of the newbuilding.
Our substantial debt levels may limit our flexibility in obtaining additional financing, refinancing credit facilities upon maturity, pursuing other business opportunities and paying distributions.
As at December 31, 2017,2018, our consolidated debt, obligations related to capital leases and advances from affiliates totaled $2.8$3.3 billion and we had the capacity to borrow an additional $189.4$175.6 million under our revolving credit facilities. These facilities may be used by us for general partnership purposes. If we obtain debt financing for existing newbuilding orders or we are awarded contracts for new LNG or LPG projects, our consolidated debt and obligations related to capital leases will increase, perhaps significantly. We will continue to have the ability to incur additional debt, subject to limitations in our credit facilities. Our level of debt could have important consequences to us, including the following:

our ability to obtain additional financing, if necessary, for working capital, capital expenditures, acquisitions or other purposes may be impaired, or such financing may not be available on favorable terms, if at all;
we will need a substantial portion of our cash flow to make principal and interest payments on our debt, reducing the funds that would otherwise be available for operations, future business opportunities and distributions to unitholders;
our debt level may make us more vulnerable than our competitors with less debt to competitive pressures or a downturn in our industry or the economy generally; and


our debt level may limit our flexibility in responding to changing business and economic conditions.

Our ability to service our debt and obligations related to capital leases depends upon, among other things, our future financial and operating performance, which is affected by prevailing economic conditions and financial, business, regulatory and other factors, some of which are beyond our control. If our operating results are not sufficient to service our current or future indebtedness or obligations related to capital leases, we will be forced to take actions such as further reducing distributions, reducing, cancellingcanceling or delaying our business activities, acquisitions, investments or capital expenditures, selling assets, seeking to restructure or refinance our debt, seeking additional debt or equity capital or seeking bankruptcy protection. We may not be able to effect any of these remedies on satisfactory terms, or at all.
Financing agreements containing operating and financial restrictions may restrict our business and financing activities.
The operating and financial restrictions and covenants in our financing arrangements and any future financing agreements for us could adversely affect our ability to finance future operations or capital needs or to engage,pursue and expand or pursue our business activities. For example, thethese financing arrangements may restrict our ability to:

incur or guarantee indebtedness;
change ownership or structure, including mergers, consolidations, liquidations and dissolutions;
make dividends or distributions when in default of the relevant loans;
make certain negative pledges and grant certain liens;
sell, transfer, assign or convey assets;


make certain investments; and
enter into new lines of business.

Some of our financing arrangements require us to maintain a minimum level of tangible net worth, to maintain certain ratios of vessel values as it relates to the relevant outstanding principal balance, to maintain a minimum level of aggregate liquidity, to maintain leverage below a maximum level of leverage and require certain of our subsidiaries to maintain restricted cash deposits. Please read "Item 5 – Operating and Financial Review and Prospects: Credit Facilities".Facilities." Our ability to comply with covenants and restrictions contained in debt instruments may be affected by events beyond our control, including prevailing economic, financial and industry conditions. If market or other economic conditions deteriorate, compliance with these covenants may be impaired. If restrictions, covenants, ratios or tests in the financing agreements are breached, a significant portion or all of the obligations may become immediately due and payable, and the lenders’ commitment to make further loans may terminate. This could lead to cross-defaults under other financing agreements and result in obligations becoming due and commitments being terminated under such agreements. We might not have or be able to obtain sufficient funds to make these accelerated payments. In addition, our obligationsA default under our existing credit facilities are secured by certainfinancing agreements could also result in foreclosure on any of our vessels and if we are unableother assets securing related loans.

Furthermore, the termination of any of our charter contracts by our customers could result in the repayment of the debt facilities to repay debt underwhich the credit facilities, the lenders could seek to foreclose on those assets.chartered vessels relate.

Restrictions in our debt agreements may prevent us from paying distributions.

The payment of principal and interest on our debt and obligations related to capital leases reduces cash available for distribution on our units. In addition, our financing agreements prohibit the payment of distributions upon the occurrence of the following events, among others:

failure to pay any principal, interest, fees, expenses or other amounts when due;
failure to notify the lenders of any material oil spill or discharge of hazardous material, or of any action or claim related thereto;
breach or lapse of any insurance with respect to vessels securing the facility;
breach of certain financial covenants;
failure to observe any other agreement, security instrument, obligation or covenant beyond specified cure periods in certain cases;
default under other indebtedness;
bankruptcy or insolvency events;
failure of any representation or warranty to be materially correct;
a change of control, as defined in the applicable agreement; andor
a material adverse effect, as defined in the applicable agreement.
We derive a substantial majority of our revenues from a limited number of customers, and the loss of any customer, charter or vessel, or any adjustment to our charter contracts could result in a significant loss of revenues and cash flow.


We have derived, and believe that we will continue to derive, a significant portion of our revenues and cash flow from a limited number of customers. Please read “Item 18 – Financial Statements: Note 4 – Segment Reporting.”

We could lose a customer or the benefits of a time-charter if:

the customer fails to make charter payments because of its financial inability, disagreements with us or otherwise;
we agree to reduce the charter payments due to us under a charter because of the customer’s inability to continue making the original payments;
the customer exercises certain rights to terminate the charter, purchase or cause the sale of the vessel or, under some of our charters, convert the time-charter to a bareboat charter (some of which rights are exercisable at any time);
the customer terminates the charter because we fail to deliver the vessel within a fixed period of time, the vessel is lost or damaged beyond repair, there are serious deficiencies in the vessel or prolonged periods of off-hire, or we default under the charter; or
under some of our time-charters, the customer terminates the charter because of the termination of the charterer’s sales agreement or a prolonged force majeure event affecting the customer, including damage to or destruction of relevant facilities, war or political unrest preventing us from performing services for that customer.

For instance, we have two LNG carriers currently on bareboat charter contracts with Awilco with original fixed contract terms ending in November 2017 and August 2018 with one-year extension options. Awilco has a purchase obligation under the charter contracts to repurchase each vessel from us at the end of their respective terms. In June 2017, we reached an agreement with Awilco to defer a portion of charter hire and extend the two LNG carrier bareboat charter contracts that were originally due to expire in November 2017 and August 2018 to December 2019, which would also include related purchase obligations on both vessels to December 2019.due at that time. However, there is no assurance that Awilco will be able to generate enough operating cash flows or have the ability to raise enough equity to pay for the charter hire deferrals and associated purchase obligations for the two LNG carriers. Further, two of the six MALT LNG Carriers in the Teekay LNG-Marubeni Joint Venture, the Marib Spirit and Arwa Spirit, are currently under long-term charter contracts expiring in 2029 with YLNG, a consortium led by Total SA.YLNG. Due to the political situationunrest in Yemen, YLNG decided to temporarily close operation of its LNG plant in Yemen in 2015. As


a result, commencing January 1, 2016, the Teekay LNG-Marubeni Joint Venture agreed in December 2015 to defersuccessive deferral arrangements with YLNG pursuant to which a portion of the charter payments forwere deferred. Concurrent with the anticipated expiry of the most current deferral arrangement, which is expected to occur within the first half of 2019, the Teekay LNG-Marubeni Joint Venture intends to enter into a further agreement with YLNG pursuant to which the Teekay-LNG Marubeni Joint Venture and YLNG will suspend the two LNG carriers from January 1, 2016 to December 31, 2016 and further deferrals were agreed with YLNG to extend the deferral period to the end of the short-term sub-chartercharter contracts for the Marib Spirit and Arwa Spirit, which is currently anticipateda period of up to be in August 2018 and March 2019, respectively, unless the short-term sub-charter contracts are further extended in accordance with their terms.three years. Should the LNG plant in Yemen resume operations during such suspended term, it is intended that YLNG will be required to repay the deferred amounts in full, plus interest over a period of time to be agreed upon.installments. However, there is no assurance if or when the LNG plant will resume operations orand, accordingly, if YLNG will be able to repay all or any portion of the deferred amounts, and this deferral period may extend beyond 2018 and 2019 as it relates to the Marib Spirit and Arwa Spirit, respectively.amounts.

If we lose a key LNG time-charter, we may be unable to redeploy the related vessel on terms as favorable to us due to the long-term nature of most LNG time-charters and the lack of an established LNG spot market. If we are unable to redeploy a LNG carrier, we will not receive any revenues from that vessel, but we may be required to pay expenses necessary to maintain the vessel in proper operating condition. In addition, if a customer exercises its right to purchase a vessel, we would not receive any further revenue from the vessel and may be unable to obtain a substitute vessel and charter. This may cause us to receive decreased revenue and cash flows from having fewer vessels operating in our fleet. Any compensation under our charters for a purchase of the vessels may not adequately compensate us for the loss of the vessel and related time-charter.

If we lose a key conventional tanker customer, we may be unable to obtain other long-term conventional charters and may become subject to the volatile spot market, which is highly competitive and subject to significant price fluctuations. If a customer exercises its right under some charters to purchase or force a sale of the vessel, we may be unable to acquire an adequate replacement vessel or may be forced to construct a new vessel. Any replacement newbuilding would not generate revenues during its construction and we may be unable to charter any replacement vessel on terms as favorable to us as those of the terminated charter.

The loss of certain of our customers, time-charters or vessels, or a decline in payments under our charters, could have a material adverse effect on our business, results of operations and financial condition and our ability to make cash distributions to unitholders.
We depend on Teekay Corporation and certain of our joint venture partners to assist us in operating our business and competing in our markets.
Pursuant to certain services agreements between us and certain of our operating subsidiaries, on the one hand, and certain direct and indirect subsidiaries of Teekay Corporation and certain of our joint venture partners, on the other hand, the Teekay Corporation subsidiaries and certain of our joint venture partners provide to us various services including, in the case of operating subsidiaries, substantially all of their managerial, operational and administrative services (including vessel maintenance, crewing for some of our vessels, purchasing, shipyard supervision, insurance and financial services) and other technical and advisory services, and in the case of Teekay LNG Partners L.P., various administrative services. Our operational success and ability to execute our growth strategy depend significantly upon Teekay Corporation’s and certain of our joint venture partners’ satisfactory performance of these services. Our business will be harmed if Teekay Corporation or certain of our joint venture partners fail to perform these services satisfactorily or if Teekay Corporation or certain of our joint venture partners stop providing these services to us.

Our ability to compete for the transportation requirements of certain LNG and oilLPG projects, and to enter into new time-charterscharter contracts, secure financings and expand our customer relationships depends largelyin part on our ability to leverage our relationshiprelationships with Teekay Corporation, and its reputation and relationships in the shipping industry. Our ability to compete for the transportation requirement of LPG projects and to enter into new charters and expand our customer relationships depends largely on our ability to leverage our relationship with one of our joint venture partners and itstheir respective reputation and relationships in the shipping industry. If Teekay Corporation or certain of our joint venture partners suffer material damage to itstheir reputation or relationships it may harm our ability to:



renew existing charters upon their expiration;
obtain new charters;
successfully interact with shipyards during periods of shipyard construction constraints;
obtain financing on commercially acceptable terms; or
maintain satisfactory relationships with our employees and suppliers.

If our ability to do any of the things described above is impaired, it could have a material adverse effect on our business, results of operations and financial condition and our ability to make cash distributions to unitholders.

Our operating subsidiaries may also contract with certain subsidiaries of Teekay Corporation and certain of our joint venture partners to have newbuildings constructed on behalf of our operating subsidiaries and to incur the construction-related financing. Our operating subsidiaries would purchase the vessels on or after delivery based on an agreed-upon price. None of our operating subsidiaries currently has this type of arrangement with Teekay Corporation or any of its affiliates or any joint venture partners.
Significant declines in natural gas and oil prices may adversely affect our growth prospects and results of operations.
GlobalAlthough global crude oil and gas prices have significantly declinedexperienced moderate recovery since mid-2014. The significantthe highs of mid-2014, prices have not returned to those same highs and remain volatile due to global and regional geopolitical, economic and strategic risks and changes. A further decline in oil prices has also contributed to depressed natural gas prices. Significant declines in natural gas or oil prices may adversely affect our business, results of operations and financial condition and our ability to make cash distributions, as a result of, among other things:



a reduction in exploration for or development of new natural gas reserves or projects, or the delay or cancelationcancellation of existing projects as energy companies lower their capital expenditures budgets, which may reduce our growth opportunities;
a reduction in both the competitiveness of natural gas as a fuel for power generation and the market price of natural gas, to the extent that natural gas prices are benchmarked to the price of crude oil;
lower demand for vessels of the types we own and operate, which may reduce available charter rates and revenue to us upon redeployment of our vessels following expiration or termination of existing contracts or upon the initial chartering of vessels, or which may result in extended periods of our vessels being idle between contracts;
customers potentially seeking to renegotiate or terminate existing vessel contracts, or failing to extend or renew contracts upon expiration, or seeking to negotiate cancelable contracts;
the inability or refusal of customers to make charter payments to us or to our joint ventures, due to financial constraints or otherwise; or
declines in vessel values, which may result in losses to us upon vessel sales or impairment charges against our earnings.
Our growth depends on continued growth in demand for LNG and LPG shipping.
Our growth strategy focuses on expansion in the LNG and LPG shipping sectors. Accordingly, our growth depends on continued growth in world and regional demand for LNG and LPG and marine transportation of LNG and LPG, as well as the supply of LNG and LPG. Demand for LNG and LPG and for the marine transportation of LNG and LPG could be negatively affected by a number of factors, such as:

increases in the cost of natural gas derived from LNG relative to the cost of natural gas generally;
increase in the cost of LPG relative to the cost of naphtha and other competing petrochemicals;
increases in the production of natural gas in areas linked by pipelines to consuming areas, the extension of existing, or the development of new, pipeline systems in markets we may serve, or the conversion of existing non-natural gas pipelines to natural gas pipelines in those markets;
decreases in the consumption of natural gas due to increases in its price relative to other energy sources or other factors making consumption of natural gas less attractive;
additional sources of natural gas, including shale gas;
availability of alternative energy sources; and
negative global or regional economic or political conditions, particularly in LNG and LPG consuming regions, which could reduce energy consumption or its growth.

Reduced demand for LNG and LPG shipping would have a material adverse effect on our future growth and could harm our business, results of operations and financial condition.
Changes in the oil markets could result in decreased demand for our conventional vessels and services in the future.
Demand for our vessels and services in transporting oil depends upon world and regional oil markets. Any decrease in shipments of crude oil in those markets could have a material adverse effect on our conventional tankers business, financial condition and results of operations. Historically, those markets have been volatile as a result of the many conditions and events that affect the price, production and transport of oil, including competition from alternative energy sources. Past slowdowns of the U.S. and world economies have resulted in reduced consumption of oil products and decreased demand for vessels and services, which reduced vessel earnings. Additional slowdowns could have similar effects on our operating results.
Changes in the LPG markets could result in decreased demand for our LPG vessels operating in the spot market.


We have several LPG carriers that operate in the LPG spot market and are either owned by us or owned or chartered-in by Exmar LPG BVBA (or the Exmar LPG Joint Venture), a joint venture entity formed pursuant to a joint venture agreement made in February 2013 between us and Belgium-based Exmar to own and charter-in LPG carriers with a primary focus on the mid-size gas carrier segment. The charters in the spot market operate for short durations and are priced on a current, or “spot,” market rate. The LPG spot market is highly volatile and fluctuates based upon the many conditions and events that affect the price, production and transport of LPG, including competition from alternative energy sources and negative global or regional economic or political conditions. Any adverse changes in the LPG markets may impact our ability to enter into economically beneficial charters when our LPG carriers complete their existing short-term charters in the LPG spot market, which may reduce vessel earnings and impact our operating results.
Future adverse economic conditions, including disruptions in the global credit markets, could adversely affect our business, financial condition, and results of operations.
Economic downturns and financial crises in the global markets could produce illiquidity in the capital markets, market volatility, increased exposure to interest rate and credit risks and reduced access to capital markets. If global financial markets and economic conditions significantly


deteriorate in the future, we may face restricted access to the capital markets or bank lending, which may make it more difficult and costly to fund future growth. Decreased access to such resources could have a material adverse effect on our business, financial condition and results of operations.
Future adverse economic conditions or other developments may affect our customers’ ability to charter our vessels and pay for our services and may adversely affect our business and results of operations.
Future adverse economic conditions or other developments relating directly to our customers may lead to a decline in our customers’ operations or ability to pay for our services, which could result in decreased demand for our vessels and services. Our customers’ inability to pay for any reason could also result in their default on our current contracts and charters. The decline in the amount of services requested by our customers or their default on our contracts with them could have a material adverse effect on our business, financial condition and results of operations.
Growth of the LNG market may be limited by infrastructure constraints and community environmental group resistance to new LNG infrastructure over concerns about the environment, safety and terrorism.
A complete LNG project includes production, liquefaction, regasification, storage and distribution facilities and LNG carriers. Existing LNG projects and infrastructure are limited, and new or expanded LNG projects are highly complex and capital-intensive, with new projects often costing several billion dollars. Many factors could negatively affect continued development of LNG infrastructure or disrupt the supply of LNG, including:

increases in interest rates or other events that may affect the availability of sufficient financing for LNG projects on commercially reasonable terms;
decreases in the price of LNG, which might decrease the expected returns relating to investments in LNG projects;
the inability of project owners or operators to obtain governmental approvals to construct or operate LNG facilities;
local community resistance to proposed or existing LNG facilities based on safety, environmental or security concerns;
any significant explosion, spill or similar incident involving an LNG facility or LNG carrier; and
labor or political unrest affecting existing or proposed areas of LNG production.

If the LNG supply chain is disrupted or does not continue to grow, or if a significant LNG explosion, spill or similar incident occurs, it could have a material adverse effect on our business, results of operations and financial condition and our ability to make cash distributions to unitholders.
Our growth depends on our ability to expand relationships with existing customers and obtain new customers, for which we will face substantial competition.
One of our principal objectives is to enter into additional long-term, fixed-rate LNG LPG and oilLPG charters. The process of obtaining new long-term charters is highly competitive and generally involves an intensive screening process and competitive bids, and often extends for several months. Shipping contracts are awarded based upon a variety of factors relating to the vessel operator, including:

shipping industry relationships and reputation for customer service and safety;
shipping experience and quality of ship operations (including cost effectiveness);
quality and experience of seafaring crew;
the ability to finance carriers at competitive rates and financial stability generally;
relationships with shipyards and the ability to get suitable berths;
construction management experience, including the ability to obtain on-time delivery of new vessels according to customer specifications;


willingness to accept operational risks pursuant to the charter, such as allowing termination of the charter for force majeure events; and
competitiveness of the bid in terms of overall price.

We compete for providing marine transportation services for potential energy projects with a number of experienced companies, including state-sponsored entities and major energy companies affiliated with the energy project requiring energy shipping services. Many of these competitors have significantly greater financial resources than we do or Teekay Corporation does. We anticipate that an increasing number of marine transportation companies – including many with strong reputations and extensive resources and experience – will enter the energy transportation sector. This increased competition may cause greater price competition for time-charters. As a result of these factors, we may be unable to expand our relationships with existing customers or to obtain new customers on a profitable basis, if at all, which would have a material adverse effect on our business, results of operations and financial condition and our ability to make cash distributions to unitholders.
Delays in deliveries of newbuildings, or in conversions or upgrades of existing vessels, or construction of LNG receiving and regasification terminals could harm our operating results and lead to the termination of related contracts.


As at April 1, 2018,2019, we had a total of 14four newbuilding vessels under construction and an LNG receiving and regasification terminal under construction. The delivery of newbuildings or vessel conversions or upgrades or construction of receiving and regasification terminals we may order or undertake or otherwise acquire, could be delayed, which would delay our receipt of revenues under the contracts for these assets. In addition, under some of our charters if delivery of a vessel to our customer is delayed, we may be required to pay liquidated damages in amounts equal to or, under some charters, almost double, the hire rate during the delay. For prolonged delays, the customer may terminate the time-charter and, in addition to the resulting loss of revenues, we may be responsible for additional, substantial liquidated damages.

Our receipt of newbuildings or of vessel conversions or upgrades, or completion of the construction of LNG receiving and regasification terminals could be delayed because of:

quality or engineering problems;
changes in governmental regulations or maritime self-regulatory organization standards;
work stoppages or other labor disturbances at the shipyard or construction site;
bankruptcy or other financial crisis of the builder;
a backlog of orders at the shipyard;
political or economic disturbances where our vessels or terminals are being or may be built;
weather interference or catastrophic event, such as a major earthquake or fire;
our requests for changes to the original vessel specifications;
shortages of or delays in the receipt of necessary construction materials, such as steel;
our inability to finance the purchase or construction of the vessels or terminals; or
our inability to obtain requisite permits or approvals.

If delivery of a vessel or the completion of an LNG receiving and regasification terminal is materially delayed, it could adversely affect our results or operations and financial condition and our ability to make cash distributions to unitholders.
We may be unable to charter or recharter vessels at attractive rates, which may lead to reduced revenues and profitability.
Our ability to charter or recharter our LNG and LPG carriers upon the expiration or termination of their current time charters and the charter rates payable under any renewal or replacement charters depend upon, among other things, the then current states of the LNG and LPG carrier markets. As of December 31, 2017, we had 14 vessels2018, in our liquefied natural gas and liquified petroleum gas operating fleet, including the Magellan Spirit chartered-in from the Teekay LNG-Marubeni Joint Venture, we had zero and eight vessels, respectively, that were unchartered or trading in the spot market, three unchartered newbuilding vessels under construction, andmarket; we had 10four and four11 vessels, respectively, with charters scheduled to expire in 20182019, excluding extension options; and 2019,two and five vessels, respectively, with charters scheduled to expire in 2020, excluding extension options. If charter rates are low when existing time charters expire, we may be required to recharter our vessels at reduced rates or even possibly at a rate whereby we incur a loss, which would harm our results of operations. Alternatively, we may determine to leave such vessels off-charter. The size of the current orderbooks for LNG carriers and LPG carriers is expected to result in the increase in the size of the world LNG and LPG fleets over the next few years. An over-supply of vessel capacity, combined with stability or any decline in the demand for LNG or LPG carriers, may result in a reduction of charter hire rates.
We may have more difficulty entering into long-term, fixed-rate LNG time-charters if the active short-term, medium-term or spot LNG shipping markets continue to develop.
LNG shipping historically has been transacted with long-term, fixed-rate time-charters, usually with terms ranging from 20 to 25 years. One of our principal strategies is to enter into additional long-term, fixed-rate LNG time-charters. In recent years, the amount of LNG traded on a


spot and short-term basis (defined as contracts with a duration of 4 years or less) has been increasing. In 2016,2018, spot and short-term trades accounted for approximately 28%30% of global LNG trade.

If the active spot, short-term or medium-term markets continue to develop, we may have increased difficulty entering into long-term, fixed-rate time-charters for our LNG carriers and, as a result, our cash flow may decrease and be less stable. In addition, an active short-term, medium-term or spot LNG market may require us to enter into charters based on changing market prices, as opposed to contracts based on a fixed rate, which could result in a decrease in our cash flow in periods when the market price for shipping LNG is depressed.
Over time, vessel valuesthe value of our vessels may fluctuate substantially,decline, which could adversely affect our operating results.
Vessel values for LNG and LPG carriers and conventional tankers can fluctuate substantially over time due to a number of different factors, including:

prevailing economic conditions in natural gas, oil and energy markets;
a substantial or extended decline in demand for natural gas, LNG, LPG or oil;
competition from more technologically advanced vessels;


increases in the supply of vessel capacity; and
the cost of retrofitting or modifying existing vessels, as a result of technological advances in vessel design or equipment, changes in applicable environmental or other regulation or standards, or otherwise.

Vessel values may decline from existing levels. If the operation of a vessel is not profitable, or if we cannot re-deployredeploy a chartered vessel at attractive rates upon charter termination, of its contract, rather than continue to incur costs to maintain and finance the vessel, we may seek to dispose of it. Our inability to dispose of the vessel at a reasonablefair market value or the disposal of the vessel at a fair market value that is lower than its book value could result in a loss on its sale and adversely affect our results of operations and financial condition. Further, if we determine at any time that a vessel’s future useful life and earnings require us to impair its value on our financial statements, we may need to recognize a significant charge against our earnings.
We have recognized vessel and goodwill write-downs in the past and we may recognize additional write-downs in the future, which will reduce our earnings and net assets.
If we determine at any time that a vessel’s value or goodwill has been impaired, we may need to recognize an impairment charge that will reduce our earnings and net assets. We review our vessels for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable, which occurs when the assets’an asset's carrying value is greater than the estimated undiscounted future cash flows the asset is expected to generate over its remaining useful life. We review our goodwill for impairment annually and if a reporting unit's goodwill carrying value is greater than the estimated fair value, the goodwill attributable to that reporting unit is impaired.

A reduction in our net assets could result in a breach of certain financial covenants contained in our credit agreements, which could limit our ability to borrow additional funds under our credit facilities or require us to repay outstanding amounts. This could harm our business, results of operations, financial condition, ability to raise capital or ability to pay distributions.

For the write-downs that occurred during 2017,2018, please read "Item 5 – Operating and Financial Review and Prospects: Management's Discussion and Analysis of Financial Condition and Results of Operations - Year Ended December 31, 20172018 versus Year Ended December 31, 2016" and2017", "Item 18 – Financial Statements: Note 188 – Intangible Assets and Goodwill" and "Note 19 – Write-Down and Loss on Sales of Vessels."
Increased technological innovation in vessel design or equipment could reduce our charter hire rates and the value of our vessels.
The charter hire rates and the value and operational life of a vessel are determined by a number of factors, including the vessel’s efficiency, operational flexibility and physical life. Efficiency includes speed, fuel economy and the ability for LNG or LPG to be loaded and unloaded quickly. More efficient vessel designs, engines or other features may increase overall vessel efficiency. Flexibility includes the ability to access LNG and LPG storage facilities, utilize related docking facilities and pass through canals and straits. Physical life is related to the original design and construction, maintenance and the impact of the stress of operations. If new LNG or LPG carriers are built that are more efficient or flexible or have longer physical lives than our vessels, competition from these more technologically advanced LNG or LPG carriers could reduce recharter rates available to our vessels and the resale value of the vessels. As a result, our business, results of operations and financial condition could be harmed.
WeActual results of new technologies or technologies upgrades may be unable to perform as per specifications ondiffer from expected results and affect our MEGI engine designs and other equipment.results of operations.
We have invested and are investing in technology upgrades such as MEGI twin engines and other equipment and designs for certain LNG carrier newbuildings.newbuildings, including, among other things, to improve fuel efficiency and vessel performance. These new engine designs and other equipment may not perform to expectations, which may result in performance issues or claims based on failure to achieve specification included in charter party agreements. Actual fuel consumption for our MEGI LNG carriers exceeds specified levels in certain charter party agreements, which may result in reimbursement by us to the charterer for the cost of the excess fuel consumed. The amount of the reimbursements generally will increase to the extent fuel prices increase, including as a result of the IMO 2020 regulations that will take effect


January 1, 2020 and limit Sulphur content in vessel fuel oils. We are considering installing additional equipment to lower fuel consumption on these vessels and taking action against the shipbuilders for failure to deliver vessels that meet anticipated levels of fuel efficiency. Continued reimbursement obligations or unrecovered capital expenditures could harm our results of operations or financial condition.
We or our joint venture partners may be unable to deliver or operate a floating store unit (or FSU) or aan LNG receiving and regasification terminal.
We are modifying onehave contracted the construction of our LNG carrier newbuildings into a FSU to service aan LNG regasification and receiving terminal in Bahrain in which we will have a 30% ownership interest (please read “Item 18 – Financial Statements: Note 6a (i)7a(i) – Equity-Accounted Investments”). We may be unable to operate the FSU efficiently, which may result in performance issues or claims based on charter party agreements. In addition, we or our joint venture partners may be unable to operate a LNG receiving and regasification terminal properly, which could reduce the expected output of this terminal. As a result, our business, results of operations and financial condition could be harmed.
Climate change and greenhouse gas restrictions may adversely impact our operations and markets.
Due to concern over the risk of climate change, a number of countries have adopted, or are considering the adoption of, regulatory frameworks to reduce greenhouse gas emissions. These regulatory measures include, among others, adoption of cap and trade regimes, carbon taxes, increased efficiency standards, and incentives or mandates for renewable energy. Compliance with changes in laws, regulations and obligations relating to climate change could increase our costs related to operating and maintaining our vessels and require us to install new emission controls, acquire allowances or pay taxes related to our greenhouse gas emissions, or administer and manage a greenhouse gas emissions program. Revenue generation and strategic growth opportunities may also be adversely affected.
Adverse effects upon the oil and gas industry relating to climate change may also adversely affect demand for our services. Although we do not expect that demand for oil and gas will lessen dramatically over the short term, in the long-term,long term, climate change may reduce the demand for oil and gas or increased regulation of greenhouse gases may create greater incentives for use of alternative energy sources. Any long-


termlong-term material adverse effect on the oil and gas industry could have a significant financial and operational adverse impact on our business that we cannot predict with certainty at this time.
We may be unable to make or realize expected benefits from acquisitions, and implementing our growth strategy through acquisitions may harm our business, financial condition and operating results.
Our growth strategy includes selectively acquiring existing LNG and LPG carriers or LNG and LPG shipping businesses.businesses as the opportunities arise. Historically, there have been very few purchases of existing vessels and businesses in the LNG and LPG shipping industries. Factors that may contribute to a limited number of acquisition opportunities in the LNG and LPG shipping industries in the near term include the relatively small number of independent LNG and LPG fleet owners and the limited number of LNG and LPG carriers not subject to existing long-term charter contracts. In addition, competition from other companies could reduce our acquisition opportunities or cause us to pay higher prices.

Any acquisition of a vessel or business may not be profitable to us at or after the time we acquire it and may not generate cash flow sufficient to justify our investment. In addition, our acquisition growth strategy exposes us to risks that may harm our business, financial condition and operating results, including risks that we may:

fail to realize anticipated benefits, such as new customer relationships, cost-savings or cash flow enhancements;
be unable to hire, train or retain qualified shore and seafaring personnel to manage and operate our growing business and fleet;
decrease our liquidity by using a significant portion of our available cash or borrowing capacity to finance acquisitions;
significantly increase our interest expense or financial leverage if we incur additional debt to finance acquisitions;
incur or assume unanticipated liabilities, losses or costs associated with the business or vessels acquired; or
incur other significant charges, such as impairment of goodwill or other intangible assets, asset devaluation or restructuring charges.

Unlike newbuildings, existing vessels typically do not carry warranties as to their condition. While we generally inspect existing vessels prior to purchase, such an inspection would normally not provide us with as much knowledge of a vessel’s condition as we would possess if it had been built for us and operated by us during its life. Repairs and maintenance costs for existing vessels are difficult to predict and may be substantially higher than for vessels we have operated since they were built. These costs could decrease our cash flow and reduce our liquidity.
Marine transportation is inherently risky, and an incident involving significant loss of or environmental contamination by any of our vessels could harm our reputation and business.
Our vessels, crew and their cargoes are at risk of being damaged, injured or lost because of events such as:

marine disasters;
bad weather or natural disasters;
mechanical failures;
grounding, fire, explosions and collisions;
piracy;

piracy (hijacking and kidnapping);
cyber attack;
human error; and
war and terrorism.

An accident involving any of our vessels could result in any of the following:

death or injury to persons, loss of property or environmental damage;
delays in the delivery of cargo;
loss of revenues from or termination of charter contracts;
governmental fines, penalties or restrictions on conducting business;
higher insurance rates; and
damage to our reputation and customer relationships generally.
Any of these results could have a material adverse effect on our business, financial condition and operating results. In addition, any damage to, or environmental contamination involving, oil production facilities serviced by our vessels could result in the suspension or curtailment of operations by our customer, which would in turn result in loss of revenues.


Our insurance may be insufficient to cover losses that may occur to our property or result from our operations.
The operation of LNG and LPG carriers and oil tankers is inherently risky. Although we carry hull and machinery (marine and war risks) and protection and indemnity insurance, all risks may not be adequately insured against, and any particular claim may not be paid. In addition, only certain of our LNG and LPG carriers carry insurance covering the loss of revenues resulting from vessel off-hire time based on its cost compared to our off-hire experience. Any significant off-hire time of our vessels could harm our business, operating results and financial condition. Any claims covered by insurance would be subject to deductibles, and since it is possible that a large number of claims may be brought, the aggregate amount of these deductibles could be material. Certain of our insurance coverage is maintained through mutual protection and indemnity associations, and as a member of such associations we may be required to make additional payments over and above budgeted premiums if member claims exceed association reserves.

We may be unable to procure adequate insurance coverage at commercially reasonable rates in the future. For example, more stringent environmental regulations have led in the past to increased costs for, and in the future may result in the lack of availability of, insurance against risks of environmental damage or pollution. A catastrophic oil spill, marine disaster or natural disasters could result in losses that exceed our insurance coverage, which could harm our business, financial condition and operating results. Any uninsured or underinsured loss could harm our business and financial condition. In addition, our insurance may be voidable by the insurers as a result of certain of our actions, such as our ships failing to maintain certification with applicable maritime regulatory organizations.

Changes in the insurance markets attributable to terrorist attacks or political change may also make certain types of insurance more difficult for us to obtain. In addition, the insurance that may be available may be significantly more expensive than our existing coverage.
Our and many of our customers’ substantial operations outside the United States expose us and them to political, governmental and economic instability, which could harm our operations.
Because our operations, and the operations of certain of our customers, are primarily conducted outside of the United States, they may be affected by economic, political and governmental conditions in the countries where we and they engage in business. Any disruption caused by these factors could harm our business or the business of these customers, including by reducing the levels of oil and gas exploration, development and production activities in these areas. We derive some of our revenues from shipping oil, LNG and LPG from politically and economically unstable regions, such as Angola and Yemen. Hostilities, strikes, or other political or economic instability in regions where we or these customers operate or where we or they may operate could have a material adverse effect on the growth of our business, results of operations and financial condition and ability to make cash distributions, or on the ability of these customers to make payments or otherwise perform their obligations to us. In addition, tariffs, trade embargoes and other economic sanctions by the United States or other countries against countries in which we operate or to which we trade may harm our business and ability to make cash distributions and a government could requisition one or more of our vessels, which is most likely during war or national emergency. Any such requisition would cause a loss of the vessel and could harm our cash flow and financial results.

Two Please see above relating to our two vessels owned bychartered out to YLNG “Item 3 – Risk Factors: We derive a substantial majority of our revenues from a limited number of customers, and the Teekay LNG-Marubeni Joint Venture, the loss of any customer, charter or vessel, or any adjustment to our charter contracts could result in a significant loss of revenues and cash flowMarib Spirit and Arwa Spirit, are currently under long-term contracts expiring in 2029 with YLNG, a consortium led by Total SA. Due to the political situation in Yemen, YLNG decided to temporarily close operation of its LNG plant in Yemen in 2015. As a result, the Teekay LNG-Marubeni Joint Venture agreed in December 2015 to defer a portion of the charter payments for the two LNG carriers from January 1, 2016 to December 31, 2016 and further deferrals were agreed with YLNG to extend the deferral period to the end of the short-term sub-charter contracts for the Marib Spirit and Arwa Spirit, which is currently anticipated to be in August 2018 and March 2019, respectively, unless the short-term sub-charter contracts are further extended in accordance with their terms. Should the LNG plant in Yemen resume operations, it is intended that YLNG will repay the deferred amounts in full, plus interest over a period of time to be agreed upon. However, there is no assurance if or when the LNG plant will resume operations or if YLNG will repay the deferred amounts, and this deferral period may extend beyond 2018 and 2019 as it relates to the Marib Spirit and Arwa Spirit, respectively. Our proportionate share of the impact of the charter payment deferral for 2017 compared to 2016 was a reduction to equity income of $5.5 million. Our proportionate share of the estimated impact of the charter payment deferral for 2018 compared to original charter rates earned prior to January 1, 2016 is estimated to be a reduction to equity income ranging from $4 million to $5 million per quarter, depending on any sub-chartering employment opportunities for the Marib Spirit and Arwa Spirit in 2018..”
Terrorist attacks, piracy, increased hostilities, political change or war could lead to further economic instability, increased costs and disruption of our business.
Terrorist attacks, piracy, the current conflicts in the Middle East, South East Asia, West Africa (Nigeria), Libya and elsewhere, and political change, may adversely affect our business, operating results, financial condition, ability to raise capital and future growth. Continuing hostilities in the


Middle East, especially among Qatar, Saudi Arabia, UAE, Yemen and elsewhere may lead to additional armed conflicts or to further acts of terrorism and civil disturbance in the United States, or elsewhere, which may contribute to economic instability and disruption of LNG, LPG and oil production and distribution, which could result in reduced demand for our services or impact on our operations and or our ability to conduct business.

In addition, LNG, LPG and oil facilities, shipyards, vessels, pipelines and oil and gas fields could be targets of future terrorist attacks and warlike operations and our vessels could be targets of pirates, hijackers, terrorists or warlike operations. Any such attacks could lead to, among other things, bodily injury or loss of life, vessel or other property damage, increased vessel operational costs, including insurance costs, and the inability to transport LNG, LPG and oil to or from certain locations. Terrorist attacks, war, piracy, hijacking or other events beyond our control that adversely affect the distribution, production or transportation of LNG, LPG or oil to be shipped by us could entitle our customers to terminate our charter contracts, which would harm our cash flow and our business.



Terrorist attacks, or the perception that LNG or LPG facilities and carriers are potential terrorist targets, could materially and adversely affect expansion of LNG and LPG infrastructure and the continued supply and export of LNG and LPG toinvolving the United States and other countries. Concern that LNG or LPG facilities may be targeted for attack by terrorists, as well as environmental concerns, has contributed to significant community resistance to the construction of a number of LNG or LPG facilities, primarily in North America. If a terrorist incident involving a LNG or LPG facility or LNG or LPG carrier did occur, in addition to the possible effects identified in the previous paragraph, the incident may adversely affect construction of additional LNG or LPG facilities in the United States and other countries or lead to the temporary or permanent closing of various LNG or LPG facilities currently in operation.
Acts of piracy on ocean-going vessels continue to be a risk, which could adversely affect our business.
Acts of piracy have historically affected ocean-going vessels trading in regions of the world such as the South China Sea, Gulf of Guinea and the Indian Ocean off the coast of Somalia. While there continues to be a significant risk of piracy in the Gulf of Aden and Indian Ocean, recently there have been increases in the frequency and severity of piracy incidents off the coast of West Africa and a resurgent piracy risk in the Straits of Malacca, Sulu and Celebes Sea and surrounding waters. If these piracy attacks result in regions in which our vessels are deployed being named on the Joint War Committee Listed Areas, war risk insurance premiums payable for such coverage canmay increase significantly and such insurance coverage may be more difficult to obtain. In addition, crew costs, including costs which may be incurred to the extent we employ on-board armed security guards and escort vessels, could increase in such circumstances. We may not be adequately insured to cover losses from these incidents, which could have a material adverse effect on us. In addition, hijacking as a result of an act of piracy against our vessels, or an increase in cost or unavailability of insurance for our vessels, could have a material adverse impact on our business, financial condition and results of operations.
A cyber-attack could materially disrupt our business
We rely on information technology systems and networks in our operations and the administration of our business. Cyber-attacks have increased in number and sophistication in recent years. Our operations could be targeted by individuals or groups seeking to sabotage or disrupt our information technology systems and networks, or to steal data. A successful cyber-attack could materially disrupt our operations, including the safety of our operations, or lead to unauthorized release of information or alteration of information on our systems. Any such attack or other breach of our information technology systems could have a material adverse effect on our business and results of operations.
Our failure to comply with data privacy laws could damage our customer relationships and expose usto litigation risks and potential fines.
Data privacy is subject to frequently changing rules and regulations, which sometimes conflict among the various jurisdictions and countries in which we provide services and continue to develop in ways which we cannot predict, including with respect to evolving technologies such as cloud computing. The European Union has adopted the General Data Privacy Regulation (or GDPR), a comprehensive legal framework to govern data collection, use and sharing and related consumer privacy rights which took effect in May 2018. The GDPR includes significant penalties for non-compliance. Our failure to adhere to or successfully implement processes in response to changing regulatory requirements in this area could result in legal liability or impairment to our reputation in the marketplace, which could have a material adverse effect on our business, financial condition and results of operations.
The ARC7 LNG carrier newbuildings for the Yamal LNG Project are customized vessels and our financial condition, results of operations and ability to make distributions on our units could be substantially affected if the Yamal LNG Project is not completed.abandoned.
On July 9, 2014, we entered into a 50/50 joint venture with China LNG (or the Yamal LNG Joint Venture) andVenture ordered six internationally-flagged icebreaker LNG carriers for a project located on the Yamal Peninsula in Northern Russia (or the Yamal LNG Project), onetwo of which newbuilding carriers delivered in January 2018. The Yamal LNG Project is a joint venture between Russia-based Novatek OAO (or Novatek) (50.1%), France-based Total S.A. (20%), China-based China National Petroleum Corporation (20%) and Silk Road Fund (9.9%).

The fivefour remaining ARC7 LNG carrier newbuildings ordered by the Yamal LNG Joint Venture, which are scheduled for delivery betweenduring the remainder of 2018 and 2020,2019, are being specifically built for the Arctic requirements of the Yamal LNG Project and will have limited redeployment opportunities to operate as conventional trading LNG carriers if the project is abandoned or cancelled. If the project is abandoned or cancelled or not completed for any reason, either before or after commencement of operations, the Yamal LNG Joint Venture may be unable to reach an agreement with the shipyard allowing for the termination of the shipbuilding contracts (since no such optional termination right exists under these contracts), change the vessel specifications


to reflect those applicable to more conventional LNG carriers and which do not incorporate ice-breaking capabilities, or find suitable alternative employment for the newbuilding vessels on a long-term basis with other LNG projects or otherwise.

The Yamal LNG Project may be abandoned or not completed for various reasons, including, among others:

failure to achieve expected operating results;
changes in demand for LNG;
adverse changes in Russian regulations or governmental policy relating to the project or the export of LNG;
technical challenges of completing and operating the complex project, particularly in extreme Arctic conditions;
labor disputes; andor
environmental regulations or potential claims.

If the project is not completed or is abandoned, proceeds if any, received from limited Yamal LNG project sponsor guarantees and potential alternative employment, if any, of the vessels and from potential sales of components and scrapping of the vessels likely would fall substantially short of the cost of the vessels to the Yamal LNG Joint Venture. Any such shortfall could have a material adverse effect on our financial condition, results of operations and ability to make cash distributions to unitholders.
Sanctions against key participants in the Yamal LNG Project could impede completion or performance of the Yamal LNG Project, which could have a material adverse effect on us.


The U.S. Treasury Department’s Office of Foreign Assets Control (or OFAC) placed Russia-based Novatek, OAO (or Novatek), a 50.1% owner of the Yamal LNG Project, on the Sectoral Sanctions Identifications List. OFAC also previously imposed sanctions on an investor in Novatek and these sanctions also remain in effect. Effective as of November 2017, theThe current restrictions on Novatek prohibit U.S. persons (and their subsidiaries) from participating in debt financing transactions of greater than 60 days maturity with Novatek and, by virtue of Novatek’s 50.1% ownership interest, the Yamal LNG Project. The European Union also imposed certain sanctions on Russia. These sanctions require a European Union license or authorization before a party can provide certain technologies or technical assistance, financing, financial assistance, or brokering with regard to these technologies. However, the technologies being currently sanctioned by the EU appear to focus on oil exploration projects, not gas projects. In addition, OFAC and other governments or organizations may impose additional sanctions on Novatek, the Yamal LNG Project or other project participants, which may further hinder the ability of the Yamal LNG Project to receive necessary financing. Although we believe that we are in compliance with all applicable sanctions, laws and regulations, and intend to maintain such compliance, the scope of these sanctions laws may be subject to change. Future sanctions may prohibit the Yamal LNG Joint Venture from performing under its contracts with the Yamal LNG Project, which could have a material adverse effect on our financial condition, results of operations and ability to make cash distributions on our units.
Failure of the Yamal LNG Project to achieve expected results could lead to a default under the time-charter contracts by the charter party.
The charter party under the Yamal LNG Joint Venture’s time-charter contracts for the Yamal LNG Project is Yamal Trade Pte. Ltd., a wholly-owned subsidiary of Yamal LNG, the project’s sponsor. If the Yamal LNG Project does not achieve expected results, the risk of charter party default may increase. Any such default could adversely affect our results of operations and ability to make cash distributions on our units. If the charter party defaults on the time-charter contracts, we may be unable to redeploy the vessels under other time-charter contracts or may be forced to scrap the vessels.

We assume credit risk by entering into agreements with unrated entities.
Some of our vessels are chartered to unrated entities and some of these unrated entities will use revenue generated from the sale of the shipped gas to pay their shipping and other operating expenses, including the charter fees. The price of the gas may be subject to market fluctuations and the LNG supply may be curtailed by start-up delays and stoppages. If the revenue generated by the charterer is insufficient to pay the charter fees, we may be unable to realize the expected economic benefit from these charter agreements. In addition, some of our financing related to certain of our LNG carrier newbuildings are with unrated entities. Any inability of these entities to meet their obligations under the financing arrangements, could have an adverse effect on our liquidity and potentially delay the deliveries of certain of our LNG carrier newbuildings.

The marine energy transportation industry is subject to substantial environmental and other regulations, which may significantly limit our operations or increase our expenses.
Our operations are affected by extensive and changing international, national and local environmental protection laws, regulations, treaties and conventions in force in international waters, the jurisdictional waters of the countries in which our vessels operate, as well as the countries of our vessels’ registration, including those governing oil spills, discharges to air and water, and the handling and disposal of hazardous substances and wastes. Many of these requirements are designed to reduce the risk of oil spills and other pollution. In addition, we believe that the heightened environmental, quality and security concerns of insurance underwriters, regulators and charterers will lead to additional regulatory requirements, including enhanced risk assessment and security requirements and greater inspection and safety requirements on


vessels. We expect to incur substantial expenses in complying with these laws and regulations, including expenses for vessel modifications and changes in operating procedures.

These requirements can affect the resale value or useful lives of our vessels, require a reduction in cargo capacity, ship modifications or operational changes or restrictions, lead to decreased availability of insurance coverage for environmental matters or result in the denial of access to certain jurisdictional waters or ports, or detention in certain ports. Under local, national and foreign laws, as well as international treaties and conventions, we could incur material liabilities, including cleanup obligations, in the event that there is a release of petroleum or other hazardous substances from our vessels or otherwise in connection with our operations. We could also become subject to personal injury or property damage claims relating to the release of or exposure to hazardous materials associated with our operations. In addition, failure to comply with applicable laws and regulations may result in administrative and civil penalties, criminal sanctions or the suspension or termination of our operations, including, in certain instances, seizure or detention of our vessels. For further information about regulations affecting our business and related requirements on us, please read “Item 4 – Information on the Partnership: B. Operations - Regulations.”

Exposure to currency exchange rate fluctuations will result in fluctuations in our cash flows and operating results.
We are paid in Euros under some of our charters, and certain of our vessel operating expenses and general and administrative expenses currently are denominated in Euros, which is primarily a function of the nationality of our crew and administrative staff. We also make payments under two Euro-denominated term loans. If the amount of our Euro-denominated obligations exceeds our Euro-denominated revenues, we must convert other currencies, primarily the U.S. Dollar, into Euros. An increase in the strength of the Euro relative to the U.S. Dollar would require us to convert more U.S. Dollars to Euros to satisfy those obligations, which would cause us to have less cash available for distribution to unitholders. In addition, if we do not have sufficient U.S. Dollars, we may be required to convert Euros into U.S. Dollars for distributions to unitholders. An increase in the strength of the U.S. Dollar relative to the Euro could cause us to have less cash available for distribution in this circumstance. We have not entered into currency swaps or forward contracts or similar derivatives to mitigate this risk.



Because we report our operating results in U.S. Dollars, changes in the value of the U.S. Dollar relative to the Euro and Norwegian Kroner also result in fluctuations in our reported revenues and earnings. In addition, under U.S. accounting guidelines, all foreign currency-denominated monetary assets and liabilities such as cash and cash equivalents, accounts receivable, restricted cash, accounts payable, accrued liabilities, advances from affiliates and long-term debt, are revalued and reported based on the prevailing exchange rate at the end of the period. This revaluation historically has caused us to report significant unrealized foreign currency exchange gains or losses each period. The primary source for these gains and losses is our Euro-denominated term loans and our Norwegian Kroner-denominated (or NOK) bonds. We incur interest expense on our NOK bonds and we have entered into cross-currency swaps to economically hedge the foreign exchange risk on the principal and interest payments of our NOK bonds. If the Norwegian Kroner depreciates relative to the U.S. Dollar beyond a certain threshold, we are required to place cash collateral with our swap providers.
Exposure to interest rate fluctuations will result in fluctuations in our cash flows and operating results.
We are exposed to the impact of interest rate changes primarily through our borrowings that require us to make interest payments based on LIBOR, EURIBOR or NIBOR. Significant increases in interest rates could adversely affect our operating margins, results of operations and our ability to service our debt. In addition, there is uncertainty as to the continued use of LIBOR in the future. LIBOR is the subject of recent national, international and other regulatory guidance and proposals for reform. These reforms and other pressures may cause LIBOR to be eliminated or to perform differently than in the past. The consequences of these developments cannot be entirely predicted but could include an increase in the cost of our variable rate indebtedness and obligations. In accordance with our risk management policy, we use interest rate swaps to reduce our exposure to market risk from changes in interest rates. The principal objective of these contracts is to minimize the risks and costs associated with our floating-rate debt.

In addition, we are exposed to credit loss in the event of non-performance by the counterparties to the interest rate swap agreements. For further information about our financial instruments at December 31, 2017,2018, that are sensitive to changes in interest rates, please read "Item 11 – Quantitative and Qualitative Disclosures About Market Risk."
Many of our seafaring employees are covered by collective bargaining agreements and the failure to renew those agreements or any future labor agreements may disrupt our operations and adversely affect our cash flows.
A significant portion of our seafarers, and the seafarers employed by Teekay Corporation and its other affiliates that crew some of our vessels, are employed under collective bargaining agreements. While some of our labor agreements have recently been renewed, crew compensation levels under future collective bargaining agreements may exceed existing compensation levels, which would adversely affect our results of operations and cash flows. We may be subject to labor disruptions in the future if our relationships deteriorate with our seafarers or the unions that represent them. Our collective bargaining agreements may not prevent labor disruptions, particularly when the agreements are being renegotiated. Any labor disruptions could harm our operations and could have a material adverse effect on our business, results of operations and financial condition and our ability to make cash distributions to unitholders.
Teekay Corporation and certain of our joint venture partners may be unable to attract and retain qualified, skilled employees or crew necessary to operate our business, or may have to pay substantially increased costs for its employees and crew.
Our success depends in large part on Teekay Corporation’s and certain of our joint venture partners’ ability to attract and retain highly skilled and qualified personnel. In crewing our vessels, we require technically skilled employees with specialized training who can perform physically demanding work. The ability to attract and retain qualified crew members under a competitive industry environment continues to put upward pressure on crew manning costs.



If we are not able to increase our charter rates to compensate for any crew cost increases, our financial condition and results of operations may be adversely affected. Any inability we experience in the future to hire, train and retain a sufficient number of qualified employees could impair our ability to manage, maintain and grow our business.
Due to our lack of diversification, adverse developments in our LNG LPG or oilLPG marine transportation businesses could reduce our ability to make distributions to our unitholders.
We rely exclusively on the cash flow generated from our LNG and LPG carriers and conventional oil tankers that operate in the LNG or LPG and oil marine transportation businesses. Due to our lack of diversification, an adverse development in the LNG LPG or oilLPG shipping industry would have a significantly greater impact on our financial condition and results of operations than if we maintained more diverse assets or lines of business.
Teekay Corporation and its affiliates may engage in competition with us.
Teekay Corporation and its affiliates and joint ventures, including its equity-accounted investee, Teekay Offshore Partners L.P. (or Teekay Offshore), may engage in competition with us. Pursuant to an omnibus agreement between Teekay Corporation, Teekay Offshore, us and other related parties, Teekay Corporation, Teekay Offshore and their respective controlled affiliates (other than us and our subsidiaries) generally have agreed not to own, operate or charter LNG carriers without the consent of our General Partner. The omnibus agreement, however, allows Teekay Corporation, Teekay Offshore or any of such controlled affiliates to:
 
acquire LNG carriers and related time-charters as part of a business if a majority of the value of the total assets or business acquired is not attributable to the LNG carriers and time-charters, as determined in good faith by the boardBoard of directorsDirectors of Teekay Corporation or the boardBoard of directorsDirectors of Teekay Offshore’s general partner; however, if at any time Teekay Corporation or Teekay Offshore completes such


an acquisition, it must offer to sell the LNG carriers and related time-charters to us for their fair market value plus any additional tax or other similar costs to Teekay Corporation or Teekay Offshore that would be required to transfer the LNG carriers and time-charters to us separately from the acquired business; or
own, operate and charter LNG carriers that relate to a bid or award for an LNG project that Teekay Corporation or any of its subsidiaries submits or receives; however, at least 180 days prior to the scheduled delivery date of any such LNG carrier, Teekay Corporation must offer to sell the LNG carrier and related time-charter to us, with the vessel valued at its “fully-built-up cost,” which represents the aggregate expenditures incurred (or to be incurred prior to delivery to us) by Teekay Corporation to acquire or construct and bring such LNG carrier to the condition and location necessary for our intended use, plus a reasonable allocation of overhead costs related to the development of such a project and other projects that would have been subject to the offer rights set forth in the omnibus agreement but were not completed.

If we decline the offer to purchase the LNG carriers and time-charters described above, Teekay Corporation or Teekay Offshore may own and operate the LNG carriers, but may not expand that portion of its business.

In addition, pursuant to the omnibus agreement, Teekay Corporation, Teekay Offshore or any of their respective controlled affiliates (other than us and our subsidiaries) may:

acquire, operate or charter LNG carriers if our General Partner has previously advised Teekay Corporation or Teekay Offshore that the boardBoard of directorsDirectors of our General Partner has elected, with the approval of its conflicts committee, not to cause us or our subsidiaries to acquire or operate the carriers;
acquire up to a 9.9% equity ownership, voting or profit participation interest in any publicly traded company that owns or operates LNG carriers; and
provide ship management services relating to LNG carriers.

IfDuring 2018, there iswas a change ofin control of Teekay Corporation orOffshore, which gives Teekay Offshore the non-competition provisionsright to elect to terminate the omnibus agreement. Termination of the omnibus agreement may terminate, which termination could have a materialan adverse effect on our business, results of operations and financial condition and our ability to make cash distributions to unitholders. We have not received any indication from Teekay Offshore that it intends to terminate the omnibus agreement.
Our General Partner and its other affiliates own a controlling interest in us and have conflicts of interest and limited fiduciary duties, which may permit them to favor their own interests to those of unitholders.
Teekay Corporation, which owns and controls our General Partner, indirectly owns our 2% general partner interest and as at December 31, 20172018 owned 31.7%31.8% of our common units. The directors and officers of our General Partner have a fiduciary duty to manage our General Partner in a manner beneficial to Teekay Corporation. Furthermore, certain directors and officers of our General Partner are directors or officers of affiliates of our General Partner. Conflicts of interest may arise between Teekay Corporation and its affiliates, including our General Partner, on the one hand, and us and our unitholders, on the other hand. As a result of these conflicts, our General Partner may favor its own interests and the interests of its affiliates over the interests of our unitholders. These conflicts include, among others, the following situations:

neither our partnership agreement nor any other agreement requires our General Partner or Teekay Corporation to pursue a business strategy that favors us or utilizes our assets, and Teekay Corporation’s officers and directors have a fiduciary duty to make decisions in the best interests of the shareholders of Teekay Corporation, which may be contrary to our interests;


executive officers of Teekay Gas Group Ltd., our recently formed subsidiary, and twothree of the directors of our General Partner also currently serve as officers or directors of Teekay Corporation;
our General Partner is allowed to take into account the interests of parties other than us, such as Teekay Corporation, in resolving conflicts of interest, which has the effect of limiting its fiduciary duty to our unitholders;
our General Partner has limited its liability and restricted its fiduciary duties under the laws of the Republic of the Marshall Islands, while also restricting the remedies available to our unitholders, and as a result of purchasing units, unitholders are treated as having agreed to the modified standard of fiduciary duties and to certain actions that may be taken by our General Partner, all as set forth in our partnership agreement;
our General Partner determines the amount and timing of our asset purchases and sales, capital expenditures, borrowings, issuances of additional partnership securities and reserves, each of which can affect the amount of cash that is available for distribution to our unitholders;
in some instances, our General Partner may cause us to borrow funds in order to permit the payment of cash distributions, even if the purpose or effect of the borrowing is to make incentive distributions to affiliates to Teekay Corporation;
our General Partner determines which costs incurred by it and its affiliates are reimbursable by us;
our partnership agreement does not restrict our General Partner from causing us to pay it or its affiliates for any services rendered to us on terms that are fair and reasonable or entering into additional contractual arrangements with any of these entities on our behalf;
our General Partner controls the enforcement of obligations owed to us by it and its affiliates; and
our General Partner decides whether to retain separate counsel, accountants or others to perform services for us.


The fiduciary duties of the officers and directors of our General Partner may conflict with those of the officers and directors of Teekay Corporation.
Our General Partner has limited fiduciary duties to manage our business in a manner beneficial to us and our partners. Our General Partner has a Corporate Secretary but does not have a Chief Executive Officer or a Chief Financial Officer. The Corporate Secretary and the non-independent director of our General Partner also serve as officers or directors of Teekay Corporation and/or other affiliates of Teekay Corporation. Consequently, these officers and directors may encounter situations in which their fiduciary obligations to Teekay Corporation or its other affiliates, on one hand, and us, on the other hand, are in conflict. The resolution of these conflicts may not always be in the best interest of us or our unitholders.
CertainBecause we are organized under the laws of the Marshall Islands, it may be difficult to serve us with legal process or enforce judgments against us, our directors or our management.
We are organized under the laws of the Marshall Islands, and all of our lease arrangements contain provisions whereby we have provided a tax indemnification to third parties, which may result in increased lease payments or terminationassets are located outside of favorable lease arrangements.
We andthe United States. In addition, certain of our joint venturesGeneral Partner's directors and officers are partynon-residents of the United States, and were partyall or a substantial portion of the assets of these non-residents are located outside the United States. As a result, it may be difficult or impossible to lease arrangements wherebybring an action against us or against these individuals in the lessorUnited States. Even if successful in bringing an action of this kind, the laws of the Marshall Islands and of other jurisdictions may prevent or restrict the enforcement of a judgment against our assets or the assets of our general partner or its directors and officers.
As a Marshall Islands entity with our headquarters in Bermuda, and with a majority of our subsidiaries being Marshall Islands entities and also having subsidiaries in other offshore jurisdictions, our operations may be subject to economic substance requirements of the European Union, which could claimharm our business.
Finance ministers of the EU rate jurisdictions for tax depreciationtransparency, governance, real economic activity and corporate tax rate. Countries that do not adequately cooperate with the finance ministers are put on a “grey list” or a “blacklist”. Various countries, including the Republic of the Marshall Islands and Bermuda, are currently on the capital expendituresblacklist.

EU member states have agreed upon a set of measures, which they can choose to apply against the listed countries, including increased monitoring and audits, withholding taxes, special documentation requirements and anti-abuse provisions. The European Commission has stated it incurredwill continue to acquiresupport member states' efforts to develop a more coordinated approach to sanctions for the listed countries in 2019. EU legislation prohibits EU funds from being channelled or transited through entities in countries on the blacklist.

We are a Marshall Islands limited partnership with our headquarters in Bermuda. A majority of our subsidiaries are Marshall Islands entities and many of our subsidiaries are either organized or registered in Bermuda. It is difficult to determine how the EU blacklisting of these vessels subjectjurisdictions will affect our business. These jurisdictions have enacted or may enact economic substance laws and regulations with which we may be obligated to comply. We understand that recently-adopted Bermudian legislation requires each Bermudian-registered entity to maintain a substantial economic presence in Bermuda and provides that a registered entity that carries on a relevant activity may comply with the economic substance requirements if (i) it is directed and managed in Bermuda, (ii) its core income-generating activities are undertaken in Bermuda with respect to the lease arrangements. As is typicalrelevant activity, (iii) it maintains adequate physical presence in these leasing arrangements, taxBermuda, (iv) it has adequate full-time employees in Bermuda with suitable qualifications and change(v) it incurs adequate operating expenditures in Bermuda in relation to the relevant activity. We do not know what actions the Marshall Islands may take, if any, to remove itself from the list; whether the EU will remove the Marshall Islands or Bermuda from the list; how quickly the EU would react to any changes in legislation of law risks are assumed by the lessee. The rentals payableMarshall Islands, Bermuda or other applicable


jurisdictions; or how EU banks or other counterparties will react while we or any of our subsidiaries remain as entities organized and existing or registered under the lease arrangements are predicated on the basislaws of certain tax and financial assumptions at the commencement of the leases. If an assumption proves to be incorrect or there is a change in the applicable tax legislation or the interpretation thereof by the United Kingdom (or UK) taxing authority (or HMRC), the lessor is entitled to increase the rentals so as to maintain its agreed after-tax margin. Under the capital lease arrangements, we do not have the ability to pass these increased rentals onto our charter party. However, the terms of the lease arrangements enable us and our joint venture partner to jointly terminate the lease arrangement on a voluntary basis at any time. In the event of an early termination of the lease arrangements, the joint venture is obliged to pay termination sums to the lessor sufficient to repay its investment in the vessels and to compensate it for the taxblacklisted countries. The effect of the terminations, including recapture of tax depreciation, if any.

We own a 70% interest in Teekay Nakilat Corporation (or the Teekay Nakilat Joint Venture), which was the lessee under three separate 30-year capital lease arrangementsEU blacklist, and any noncompliance by us with a third party for three LNG carriers (or the RasGas II LNG Carriers). Under the terms of the leasing arrangements for the RasGas II LNG Carriers, the lessor claimed tax depreciation on the capital expenditures it incurredany legislation adopted by applicable countries to acquire these vessels. As is typical in these leasing arrangements, tax and change of law risks were assumed by the lessee, in this case the Teekay Nakilat Joint Venture. Lease payments under the lease arrangements were based on certain tax and financial assumptions at the commencement of the leases and subsequently adjusted to maintain the lessor’s agreed after-tax margin. On December 22, 2014, the Teekay Nakilat Joint Venture terminated the leasing of the RasGas II LNG Carriers. However, the Teekay Nakilat Joint Venture remains obligated to the lessor to maintain the lessor’s agreed after-tax marginachieve removal from the commencement of the lease to the lease termination datelist, could have a material adverse effect on our business, financial condition and as at December 31, 2017, the Teekay Nakilat Joint Venture’s carrying amount of this estimated tax indemnification guarantee was $12.7 million (December 31, 2016 – $13.3 million).  Additionally, as at December 31, 2017, the Teekay Nakilat Joint Venture had $7.0 million (December 31, 2016 – $6.8 million) on deposit with the lessor as security against any future claims.

The HMRC has been challenging the use of similar lease structures in the UK courts. One of those challenges was eventually decided in favor of HMRC (Lloyds Bank Equipment Leasing No. 1 or LEL1), with the lessor and lessee choosing not to appeal further. The LEL1 tax case concluded that capital allowances were not available to the lessor. On the basis of this conclusion, HMRC is now asking lessees on other leases, including the Teekay Nakilat Joint Venture, to accept that capital allowances are not available to their lessor. The Teekay Nakilat Joint Venture does not accept this contention and has informed HMRC of this position. It is not known at this time whether the Teekay Nakilat Joint Venture would eventually prevail in court. If the former lessor of the RasGas II LNG Carriers were to lose on a similar claim from HMRC, our 70% share of the Teekay Nakilat Joint Venture's potential exposure is estimated to be approximately $44 million. Such estimate is primarily based on information received from the lessor.

In addition, the subsidiaries of another joint venture formed to service the Tangguh LNG project in Indonesia have lease arrangements with a third party for two LNG carriers. The terms of the lease arrangements provide similar tax and change of law risk assumption by this joint venture as we have with the three RasGas II LNG Carriers.operating results.
Our joint venture arrangements impose obligations upon us but limit our control of the joint ventures, which may affect our ability to achieve our joint venture objectives.
For financial or strategic reasons, we conduct a portion of our business through joint ventures. Generally, we are obligated to provide proportionate financial support for the joint ventures although our control of the business entity may be substantially limited. Due to this limited control, we generally have less flexibility to pursue our own objectives through joint ventures or to access available cash of the joint ventures than we would with our own subsidiaries. There is no assurance that our joint venture partners will continue their relationships with us in the future or that we will be able to achieve our financial or strategic objectives relating to the joint ventures and the markets in which they operate. In addition, our joint venture partners may have business objectives that are inconsistent with ours, experience financial and other difficulties that may affect the success of the joint venture or be unable or unwilling to fulfill their obligations under the joint ventures, which may affect our financial condition or results of operations.
TAX RISKSTax Risks
In addition to the following risk factors, you should read “Item 10.10 – Additional Information —Information: Taxation” for a more complete discussion of the expected material U.S. federal and non-U.S. income tax considerations relating to us and the ownership and disposition of our units.


United States unitholders will be required to pay U.S. taxes on their share of our income even if they do not receive any cash distributions from us.
U.S. citizens, residents or other U.S. taxpayers will be required to pay U.S. federal income taxes and, in some cases, U.S. state and local income taxes on their share of our taxable income, whether or not they receive cash distributions from us. U.S. unitholders may not receive cash distributions fromtax authorities could treat us equal to their share of our taxable income or even equal to the actual tax liability that results from their share of our taxable income.
Because distributions may reduceas a common unitholder’s tax basis in our common units, common unitholders may realize greater gain on the disposition of their common units than they otherwise may expect, and common unitholders may“passive foreign investment company,” which could have a tax gain even if the price they receive is less than their original cost.
If common unitholders sell their common units, they will recognize gain or loss foradverse U.S. federal income tax purposes that is equalconsequences to the difference between the amount realized and their tax basis in those common units. Prior distributions in excess of the total net taxable income allocated decrease a common unitholder’s tax basis and will, in effect, become taxable income if common units are sold at a price greater than their tax basis, even if the price received is less than the original cost. Assuming we are notU.S. holders.
A non-U.S. entity treated as a corporation for U.S. federal income tax purposes a substantial portion of the amount realized on a sale of common units, whether or not representing gain, may be ordinary income.
The after-tax benefit of an investment in the common units may be reduced if we are not treated as a partnership for U.S. federal income tax purposes.
The anticipated after-tax benefit of an investment in common units may be reduced if we are not treated as a partnership for U.S. federal income tax purposes. If we are not treated as a partnership for U.S. federal income tax purposes, we wouldwill be treated as a corporation“passive foreign investment company” (or PFIC), for such purposes in any taxable year for which either (a) at least 75% of its gross income consists of “passive income,” or (b) at least 50% of the average value of the entity’s assets is attributable to assets that produce or are held for the production of “passive income.” For purposes of these tests, “passive income” includes dividends, interest, gains from the sale or exchange of investment property and common unitholders could suffer material adverse taxrents and royalties (other than rents and royalties that are received from unrelated parties in connection with the active conduct of a trade or economic consequences,business). By contrast, income derived from the performance of services does not constitute “passive income.”

There are legal uncertainties involved in determining whether the income derived from our time-chartering activities constitutes rental income or income derived from the performance of services, including the following:

The ratio of taxabledecision in Tidewater Inc. v. United States, 565 F.3d 299 (5th Cir. 2009), which held that income to distributions with respect to common units wouldderived from certain time-chartering activities should be expected to increase because items would not be allocated to accounttreated as rental income rather than services income for any differences between the fair market value and the basis of our assets at the time our common units are issued.
Common unitholders may recognize income or gain on any change in our status from a partnership to a corporation that occurs while they hold common units.
We would not be permitted to adjust the tax basispurposes of a secondary market purchaser in our assets under Section 743(b)foreign sales corporation provision of the Internal Revenue Code of 1986, as amended (or the Code). As a result, a person who purchases common units from a common unitholderHowever, the Internal Revenue Service (or IRS) stated in an Action on Decision (AOD 2010-01) that it disagrees with, and will not acquiesce to, the way that the rental versus services framework was applied to the facts in the secondary market may realize materially more taxableTidewater decision, and in its discussion stated that the time charters at issue in Tidewater would be treated as producing services income each yearfor PFIC purposes. The IRS’s statement with respect to Tidewater cannot be relied upon or otherwise cited as precedent by taxpayers. Consequently, in the units. This could reduceabsence of any binding legal authority specifically relating to the value of common unitholders’ common units.
Common unitholdersstatutory provisions governing PFICs, there can be no assurance that the IRS or a court would not follow the Tidewater decision in interpreting the PFIC provisions of the Code. Nevertheless, based on our and our subsidiaries’ current assets and operations, we intend to take the position that we are not now and have never been a PFIC. No assurance can be entitledgiven, however, that this position would be sustained by a court if contested by the IRS, or that we would not constitute a PFIC for any future taxable year if there were to claimbe changes in our assets, income or operations.

If the IRS were to determine that we are or have been a PFIC for any credit against theirtaxable year during which a U.S. federal incomeHolder (as defined below under "Item 10 – Additional Information: Material U.S. Federal Income Tax Considerations") held units, such U.S. Holder would face adverse tax liability for non-U.S. incomeconsequences. For a more comprehensive discussion regarding the tax liabilities incurred by us.

We are subject to U.S. tax on such income on a gross basis (that is, without any allowance for deductions) at a rate of 4%. The imposition of this tax would have a negative effect ontaxes, which reduces our business and would result in decreased cash available for distribution to common unitholders. As to any net income that is effectively connected with a U.S. tradepartners.
We or business, we would beour subsidiaries are subject to tax on that net income atin certain jurisdictions in which we or our subsidiaries are organized, own assets or have operations, which reduces the corporate tax rateamount of 21%, plus branch profits tax on our net earnings after corporate tax of 30%. The imposition of this tax would have a negative effect on our business and would result in decreased cash available for distributiondistribution. In computing our tax obligations in these jurisdictions, we are required to common unitholders.
We also may be considered a passive foreign investment company (or PFIC)take various tax accounting and reporting positions on matters that are not entirely free from doubt and for U.S. federal income tax purposes. U.S. shareholders of a PFIC are subject to an adverse U.S. federal income tax regime with respect to the income derived by the PFIC, the distributions they receivewhich we have not received rulings from the PFIC, andgoverning authorities. We cannot assure you that upon review of these positions, the gain, if any, they derive from the sale or other disposition of their interestsapplicable authorities will agree with our positions. A successful challenge by a tax authority could result in the PFIC.

Please read “Item 10 – Additional Information: Taxation – United States Tax Consequences — Possible Classification as a Corporation.”
Theadditional tax treatment of publicly traded partnerships or an investment in our units could be subject to potential legislative, judicial or administrative changes or differing interpretations, possiblyimposed on a retroactive basis.
The present U.S. federal income tax treatment of publicly traded partnerships, including us or an investment in our units may be modified by administrative, legislative or judicial interpretation at any time. For example, members of Congress propose and consider substantive changes to the existing U.S. federal income tax laws that affect publicly traded partnerships. Further, final Treasury Regulations were issued early last year interpreting the scope of activities that generate qualifying income under Section 7704 of the Code. We believe that the income we currently treat as qualifying income satisfies the requirements for qualifying income under the final regulations. However, in furtherance of Executive Orders issued by the current administration, the U.S. Treasury Department has initiated a comprehensive review of all tax regulations. Should the final regulations be withdrawn or otherwise deemed inapplicable, we would need to rely on other guidance to determine if we satisfy the qualifying income exception, including the ruling that we received from the Internal Revenue Service (or the IRS) in connection with our initial public offering that the income we derive from transporting LNG and crude oil pursuant to time charters existing at the time of our initial public offering is qualifying income within the meaning of Section 7704, which ruling may under certain circumstances be revoked or modified by the IRS retroactively. Furthermore, there could be some uncertainty as to whether we would be classified as a partnership for


U.S. federal income tax purposes. Any modification to the U.S. federal income tax laws may be applied retroactively and could make it more difficult or impossible for us to meet the exception for certain publicly traded partnerships to be treated as partnerships for U.S. federal income tax purposes. We are unable to predict whether any of these changes or other proposals will ultimately be enacted. Any such changes could negatively impact the amount of cash available for distribution to our unitholders and the value of an investment in our units.
If the IRS contests the U.S. federal income tax positions we take, the value of our units could be adversely affected and the costs of any such contest will reduce cash available for distribution to unitholders. The procedures for assessing and collecting taxes due with respect to partnerships for taxable years beginning after December 31, 2017, have been altered in a manner that could substantially reduce cash available for distribution to unitholders.
The IRS may contest the U.S. federal income tax positions we take and there is no assurance that our tax positions would be sustained by a court. Any contest with the IRS may materially and adversely affect the value of our units. In addition, the costs of any contest with the IRS will be borne by ussubsidiaries, further reducing the cash available for distributiondistribution. We have established reserves in our financial statements that we believe are adequate to cover our unitholders.

The proceduresliability for auditing large partnerships and for assessing and collecting taxes due (including applicable penalties and interest) with respectany such additional taxes. We cannot assure you, however, that such reserves will be sufficient to taxable years beginning after December 31, 2017 as acover any additional tax liability that may be imposed on our subsidiaries. In addition, changes in our operations or ownership could result of a partnership audit have been changed. Unless we are eligible to (and choose to) elect to issue revised Schedules K-1 toin additional tax being imposed on us or on our partners with respect to an audited and adjusted return, the IRS may assess and collect taxes (including any applicable penalties and interest) directly from ussubsidiaries in the yearjurisdictions in which the audit is completed under the new rules. If weoperations are required to pay taxes, penalties and interest as the result of audit adjustments, cash available for distribution to our unitholders may be substantially reduced. In addition, because payment would be due for the taxable year in which the audit is completed, unitholders during that taxable year would bear the expense of the adjustment even if they were not unitholders during the audited taxable year.
The IRS may challenge the manner in which we prorate our items of income, gain, loss and deduction between transferors and transferees of our common units and, if successful, we may be required to change the allocation of items of income, gain, loss and deduction among our common unitholders.
We generally prorate our items of income, gain, loss and deduction between transferors and transferees of our units each month based upon the ownership of our common units on the first business day of each month, instead of on the basis of the date a particular unit is transferred. Treasury Regulations allow a similar monthly simplifying convention starting with our taxable years beginning January 1, 2016. However, such regulations do not specifically authorize all aspects of the proration method we have adopted. If the IRS were to challenge our proration method, we may be required to change the allocation of items of income, gain, loss and deduction among our common unitholders.
U.S. tax-exempt entities and non-U.S. persons face unique U.S. tax issues from owning units that may result in adverse U.S. tax consequences to them.
Investments in units by U.S. tax-exempt entities, including individual retirement accounts (known as IRAs), other retirement plans and non-U.S. persons raise issues unique to them. Assuming we are classified as a partnership for U.S. federal income tax purposes, virtually all of our income allocated to organizations exempt from U.S. federal income tax will be unrelated business taxable income and generally will be subject to U.S. federal income tax. In addition, non-U.S. persons may be subject to a 4% U.S. federal income tax on the U.S. source portion of our gross income attributable to transportation that begins or ends (but not both) in the United States, or distributions to them may be reduced on account of withholding of U.S. federal income tax by us in the event we are treated as having a fixed place of business in the United States or otherwise earn U.S. effectively connected income, unless an exemption applies and they file U.S. federal income tax returns to claim such exemption. Furthermore, the U.S. federal income tax consequences to U.S. tax-exempt entities and non-U.S. persons with respect to an investment in our preferred units is uncertain. Please read "Item 10 — Additional Information: Taxation — United States Tax Consequences — Tax-Exempt Organizations and Non-U.S. Investors."
Teekay Corporation owns less than 50% of our outstanding equity interests, which could cause certain of our subsidiaries and us to be subject to additional tax.
Certain of our subsidiaries are and have been classified as corporations for U.S. federal income tax purposes. As such, these subsidiaries would be subject to U.S. federal income tax on the U.S. source portion of our income attributable to transportation that begins or ends (but not both) in the United States if they fail to qualify for an exemption from U.S. federal income tax (the Section 883 Exemption).conducted. For example, Teekay Corporation indirectly owns less than 50% of certainthe value of our subsidiaries’outstanding units but has voting control of us and therefore we believe that we do not satisfy the requirements of the exemption from U.S. taxation under Section 883 of the Code and our outstanding equity interests. Consequently, we expect these subsidiaries failedU.S. source income is subject to qualify fortaxation under Section 887 of the Section 883 Exemption in 2016 and that Teekay LNG Holdco L.L.C., our sole remaining regarded corporate subsidiary as of January 1, 2016, failed to qualify for the Section 883 Exemption in 2016 and will fail to so qualify in 2017 and subsequent tax years. Any resulting imposition of U.S. federal income taxes will result in decreased cash available for distribution to unitholders. Please read “Item 10 – Additional Information: Taxation – United States Tax Consequences –Taxation of Our Subsidiary Corporations.”

In addition, if we are not treated as a partnership for U.S. federal income tax purposes, we expect that we also would fail to qualify for the Section 883 Exemption and that any resulting imposition of U.S. federal income taxes would result in decreased cash available for distribution to unitholders.Code.

A unitholder’s taxable income or loss with respect to a common unit each year will depend upon a number of factors, including the nature and fair market value ofUnited States, which is not within our assets at the time the holder acquired the common unit, whether we issue additional units or whether we engage in certain other transactions, and the manner in which our items of income, gain, loss and deduction are allocated among our partners. For this purpose, we determine the value of our assets and the relative amounts of our items of income, gain, loss and deduction allocable to our common unitholders and our General Partner as holder of the incentive distribution rights by reference to the value of our interests, including the incentive distribution rights. The IRS may challenge any valuation determinations that we make, particularly as to the incentive distribution rights, for which there is no public market. In addition, the IRS could challenge certain other aspects of the manner in which we determine the relative allocations made to our common unitholders and to the General Partner as holder of our incentive distribution rights. A successful IRS challenge to our valuation or allocation methods could increase the amount of net taxable income and gain realized by a common unitholder with respect to a common unit. The IRS could also challenge certain other tax positions that we have taken, including our position that certain of our subsidiaries that have been classified as corporations for U.S. federal income tax purposes in past years are not PFICs for federal income tax purposes. Any such IRS challenges, whether or not successful, could adversely affect the value of our common units.complete control.
Unitholders may be subject to income tax in one or more non-U.S. countries, including Canada, as a result of owning our units if, under the laws of any such country, we are considered to be carrying on business there. Such laws may require unitholders to file a tax return with, and pay taxes to, those countries. Any foreign taxes imposed on us or any of our subsidiaries will reduce our cash available for distribution to unitholders.
Unitholders may be subject to tax in one or more countries, including Canada, as a result of owning our units if, under the laws of any such country, we are considered to be carrying on business there. If unitholders are subject to tax in any such country, unitholders may be required to file a tax return with, and pay taxes to, that country based on their allocable share of our income. We may be required to reduce distributions to unitholders on account of any withholding obligations imposed upon us by that country in respect of such allocation to unitholders. The United States may not allow a tax credit for any foreign income taxes that unitholders directly or indirectly incur.

Item 4.Information on the Partnership
A.Overview, History and Development
Overview and History
Teekay LNG Partners L.P. is an international provider of marine transportation services for LNG, LPG and crude oil. We were formed in 2004 by Teekay Corporation (NYSE: TK), a portfolio manager of marine services to the global oil and natural gas industries, to expand its operations in the LNG shipping sector. Our primary growth strategy focuses on expandingservicing our customers through our fleet of LNG and LPG carriers under medium to long-term, fixed-rate charters. In executing our growth strategy, we may engage in vessel or business acquisitions or enter into joint ventures and partnerships with companies that provide increased access to emerging opportunities from global expansion of the LNG and LPG sectors. We seek to leverage the expertise, relationships and reputation of Teekay Corporation and its affiliates to pursue these opportunities in the LNG and LPG sectors and may consider other opportunities to which our competitive strengths are well suited, including entering into the LNG receiving and regasification terminal business. We view our conventional tanker fleet primarily as a source of stable cash flow as we seek to continue to expand our LNG and LPG operations.

Please see “Item 5 – Operating and Financial Review and Prospects: Management’s Discussion and Analysis of Financial Condition and Results of Operations – Significant Developments in 20172018 and Early 2018.2019.

As of December 31, 2017,2018, our fleet, excluding newbuildings, consisted of 3543 LNG carriers (including the six MALT LNG Carriers, four RasGas 3 LNG Carriers, four Angola LNG Carriers, onethree Pan Union LNG Carriers, one Exmar LNG Carrier and two ExmarARC7 LNG carriers (or the Yamal LNG Carriers) that are all accounted for under the equity method), 2729 LPG and multi-gas carriers (including the 2022 Exmar LPG Carriers that are accounted for under the equity method), fourone Suezmax-class crude oil tankers,tanker, and one Handymax product tanker, all of which are double-hulled. Our fleet is relatively young and has an average age of approximately eight years for our LNG carriers, approximately nineeight years for our LPG and multi-gas carriers and approximately 1312 years for our conventional tankers (Suezmax and Handymax), compared to world averages of 11,10, 15 and 10 years, respectively, as of December 31, 2017.2018. As at December 31, 2017,2018, we had 15six LNG carrier newbuildings scheduled for delivery between 2018 and 2020, three LPG carrier newbuildings scheduled for delivery during 2018in 2019, and one LNG receiving and regasification terminal under construction scheduled for completion in 2019.

Our fleets of LNG and LPG carriers (excluding newbuildings but including equity-accounted vessels) currently have approximately 5.67.2 million and 0.80.9 million cubic meters of total capacity, respectively. The aggregate capacity of our conventional tanker fleet is approximately 0.70.2 million deadweight tonnes (or dwt).

We were formed under the laws of the Republic of The Marshall Islands as a limited partnership, Teekay LNG Partners L.P., on November 3, 2004, and maintain our principal executive offices at 4th Floor, Belvedere Building, 69 Pitts Bay Road, Hamilton, HM 08, Bermuda. Our telephone number at such address is (441) 298-2530.
B.Operations


Our Fleet and Our Charters
We generate revenues by charging customers for the transportation of their LNG, LPG and crude oil using our vessels. The majority of these services are provided through either a time-charter or bareboat charter contract, where vessels are chartered to customers for a fixed period of time at rates that are generally fixed but may contain a variable component based on inflation, interest rates or current market rates.

Our vessels and our regasification terminal under construction in Bahrain primarily operate under fixed-rate contracts with major energy and utility companies. As of December 31, 2017,2018, the average remaining term for these contracts, including assets under construction, iswas approximately 1210 years for our LNG carriers and regasification terminal, approximately two years for our LPG carriers and approximately half a year for our conventional tankers (Suezmax and Handymax)tanker (Handymax), subject, in certain circumstances, to termination or vessel purchase rights.

“Hire” rate refers to the basic payment from the customer for the use of a vessel. Hire is payable monthly, in advance, in U.S. Dollars or Euros, as specified in the charter. The hire rate generally includes two components – a capital cost component and an operating expense component. The capital cost component typically approximates the amount we are required to pay under vessel financing obligations and, for two of our conventional tankers, adjusts for changes in the floating interest rates relating to the underlying vessel financing. The operating expense


component, which adjusts annually for inflation, is intended to compensate us for vessel operating expenses. In addition, we may receive additional revenues beyond the fixed hire rate when current market rates exceed specified amounts under our time-charter contracts for two of our Suezmax tankers.

Hire payments may be reduced or, under some charters, we must pay liquidated damages, if the vessel does not perform to certain of its specifications, such as if the average vessel speed falls below a guaranteed speed or the amount of fuel consumed to power the vessel under normal circumstances exceeds a guaranteed amount.

When a vessel is “off-hire” – or not available for service – the customer generally is not required to pay the hire rate and we are responsible for all costs. Prolonged off-hire may lead to vessel substitution or termination of the time-charter. A vessel will typically be deemed to be off-hire if it is in dry dock unless our contract specifies drydocking is not considered off-hire. We must periodically dry dock each of our vessels for inspection, repairs and maintenance and any modifications to comply with industry certification or governmental requirements. In addition, a vessel generally will be deemed off-hire if there is a loss of time due to, among other things: operational deficiencies; equipment breakdowns; delays due to accidents, crewing strikes, certain vessel detentions or similar problems; or our failure to maintain the vessel in compliance with its specifications and contractual standards or to provide the required crew.
Liquefied Natural Gas Segment
LNG Carriers
The LNG carriers in our liquefied natural gas segment compete in the LNG market. LNG carriers are usually chartered to carry LNG pursuant to time-charter contracts, where a vessel is hired for a fixed period of time and the charter rate is payable to the owner on a monthly basis. LNG shipping historically has been transacted with long-term, fixed-rate time-charter contracts. LNG projects require significant capital expenditures and typically involve an integrated chain of dedicated facilities and cooperative activities. Accordingly, the overall success of an LNG project depends heavily on long-range planning and coordination of project activities, including marine transportation. Most shipping requirements for new LNG projects continue to be provided on a long-term basis, though the levels of spot voyages (typically consisting of a single voyage), short-term time-charters and medium-term time-charters have grown in the past few years. The amount of LNG traded on a spot and short-term basis (defined as contracts with a duration of 4 years or less) has increased from approximately 19%10% of total LNG tradesupply in 2010 to approximately 28%30% in 2016.2018.

In the LNG market, we compete principally with other private and state-controlled energy and utilities companies that generally operate captive fleets, and independent ship owners and operators. Many major energy companies compete directly with independent owners by transporting LNG for third parties in addition to their own LNG. Given the complex, long-term nature of LNG projects, major energy companies historically have transported LNG through their captive fleets. However, independent fleet operators have been obtaining an increasing percentage of charters for new or expanded LNG projects as some major energy companies have continued to divest non-core businesses.

LNG carriers transport LNG internationally between liquefaction facilities and import terminals. After natural gas is transported by pipeline from production fields to a liquefaction facility, it is supercooled to a temperature of approximately negative 260 degrees Fahrenheit. This process reduces its volume to approximately 1/600th of its volume in a gaseous state. The reduced volume facilitates economical storage and transportation by ship over long distances, enabling countries with limited natural gas reserves or limited access to long-distance transmission pipelines to import natural gas. LNG carriers include a sophisticated containment system that holds the LNG and provides insulation to reduce the amount of LNG that boils off naturally. The natural boil off is either used as fuel to power the engines on the ship or it can be reliquefied and put back into the tanks. LNG is transported overseas in specially built tanks in double-hulled ships to a receiving terminal, where it is offloaded and stored in insulated tanks. In regasification facilities at the receiving terminal, the LNG is returned to its gaseous state (or regasified) and then shipped by pipeline for distribution to natural gas customers.

With the exception of the Arctic Spirit and Polar Spirit, which are the only two ships in the world that utilize the Ishikawajima Harima Heavy Industries Self Supporting Prismatic Tank IMO Type B (or IHI SPB) independent tank technology, our fleet makes use of oneuses two of the Gaz Transport and Technigaz (or GTT) membrane containment systems. The GTT membrane systems are used in the majority of LNG tankers now being constructed. New LNG carriers generally have an expected lifespan of approximately 35 to 40 years. Unlike the oil tanker industry, there are currently no regulations that require the phase-out from trading of LNG carriers after they reach a certain age. As at December 31,


2017, 2018, our LNG carriers, excluding newbuilding vessels but including equity-accounted vessels, had an average age of approximately eight years, compared to the world LNG carrier fleet average age of approximately 1110 years. In addition, as at that date, there were approximately 502555 vessels in the world LNG fleet and approximately 119136 additional LNG carriers under construction or on order for delivery through 2020.2022.

Other Assets
We have a 30% ownership interest in an LNG receiving and regasification terminal under construction in Bahrain. The construction of this terminal is expected to be completed in mid-2019 and will be operated under a 20-year agreement with National Oil & Gas Authority (or Nogaholding).

Liquefied Petroleum Gas Segment
LPG and Multi-gas Carriers
LPG shipping involves the transportation of three main categories of cargo: liquid petroleum gases, including propane, butane and ethane; petrochemical gases, including ethylene, propylene and butadiene; and ammonia.

In the LPG market, we compete principally with independent ship owners and operators, and other private and state-controlled energy and chemical companies that generally operate captive fleets.

As of December 31, 2017,2018, our LPG and multi-gas carriers (excluding newbuildings but including(including equity-accounted vessels) had an average age of approximately nineeight years, compared to the world LPG carrier fleet average age of approximately 15 years. As of that date, the worldwide LPG tanker fleet consisted of approximately 1,4521,451 vessels and approximately 7174 additional LPG vessels were on order for delivery through 2020.2022. LPG carriers range in


size from approximately 100 to approximately 88,000 cubic meters. Approximately 43%47% of the vessels in the worldwide fleet are less than 5,000 cubic meters in size. New LPG carriers generally have an expected lifespan of approximately 30 to 35 years.

LPG carriers are mainly chartered to carry LPG on time-charters, contracts of affreightment or spot voyage charters. The two largest consumers of LPG are residential users and the petrochemical industry. Residential users, particularly in developing regions where electricity and gas pipelines are not developed, do not have fuel switching alternatives and generally are not LPG price sensitive. The petrochemical industry, however, has the ability to switch between LPG and other feedstock fuels depending on price and availability of alternatives.

The following table provides information about our LPG and multi-gas carriers in our operating fleet as of December 31, 2017.2018.

Other Assets
We also have a 30% ownership interest in an LNG receiving and regasification terminal under construction in Bahrain. The construction of this terminal is expected to be completed in early-2019 and will be operated under a 20-year agreement with National Oil & Gas Authority (or Nogaholding).
Conventional Tanker Segment
Oil has been the world’s primary energy source for decades. Seaborne crude oil transportation is a mature industry. The two main types of oil tanker operators are major oil companies (including state-owned companies) that generally operate captive fleets, and independent operators that charter out their vessels for voyage or time-charter use. Most conventional oil tankers controlled by independent fleet operators are hired for one or a few voyages at a time at fluctuating market rates based on the existing tanker supply and demand. These charter rates are extremely sensitive to this balance of supply and demand, and small changes in tanker utilization have historically led to relatively large short-term rate changes. Long-term, fixed-rate charters for crude oil transportation, such as those applicable to our conventional tanker fleet, are less typical in the industry. As used in this discussion, “conventional” oil tankers exclude those vessels that can carry dry bulk and ore, tankers that currently are used for storage purposes and shuttle tankers that are designed to transport oil from offshore production platforms to onshore storage and refinery facilities.

Oil tanker demand is a function of several factors, primarily the locations of oil production, refining and consumption and world oil demand and supply, while oil tanker supply is primarily a function of new vessel deliveries, vessel scrapping and the conversion or loss of tonnage.

We compete in the Suezmax crude oil tanker market. Our competition in the Suezmax market is also affected by the availability of other size vessels that compete in these markets. Suezmax size vessels can compete for many of the same charters for which Aframax tankers compete.

The majority of crude oil tankers range in size from approximately 80,000 dwt to approximately 320,000 dwt. Suezmax tankers, which typically range from 120,000 dwt to 200,000 dwt, are the mid-size of the various primary oil tanker types. As of December 31, 2017, the world tanker fleet included 499 conventional Suezmax tankers, representing approximately 14% of worldwide oil tanker capacity, excluding tankers under 10,000 dwt.

As of December 31, 2017,2018, our conventional tankers had an average age of approximately 1312 years, compared to the average age for the world conventional tanker fleet of approximately 10 years. New conventional tankers generally have an expected lifespan of approximately 25 to 30 years, based on estimated hull fatigue life.

The following table provides additional information about our conventional oil tankers in our operating fleet as of December 31, 2017.

Business Strategies
Our primary long-term business objective is to increaseexpand our cash available for distribution. However, based on capitalcore businesses globally in order to service our customers' growing gas transportation requirements for committed growth projects and scheduled debt repayment obligations, coupled with weakness in the energy and master limited partnership capital markets,which we believe it is in the best interests ofwill add long-term value for our common unitholders to conserve more of our internally generated cash flows to fund these projects and to reduce debt levels. As a result, in December 2015, we reduced our quarterly distributions on our common units and our near-term business strategy is primarily to focus on funding and implementing existing growth projects and repaying or refinancing scheduled debt obligations.unitholders. Our operating cash flows remain largely stable and growing, supported by a large and well-diversified portfolio of fee-based contracts with high-quality counterparties.

We intend to achieve our long-term business objective, as stated above, by executing the following strategies:

Provide superior customer service by maintaining high reliability, safety, environmental and quality standards. LNG and LPG project operators seek LNG and LPG transportation partners that have a reputation for high reliability, safety, environmental and quality


standards. We seek to leverage our own and Teekay Corporation’s operational expertise to create a sustainable competitive advantage with consistent delivery of superior customer service.

Expand our LNG and LPG business globally. We seek to capitalize on opportunities emerging from the global expansion of the LNG and LPG sectors by selectively targeting:
projects that involve medium-tomedium to long-term, fixed-rate charters;
cost-effective LNG and LPG newbuilding contracts;
joint ventures and partnerships with companies that may provide increased access to opportunities in attractive LNG and LPG importing and exporting geographic regions;
strategic vessel and business acquisitions; and
specialized projects in adjacent areas of the business, including floating storage and regasification units.

Safety, Management of Ship Operations and Administration
Teekay Corporation, through its subsidiaries, assists us in managing our ship operations, other than the vessels owned or chartered-in by our joint ventures with Exmar, which are commercially and technically managed by Exmar, and two of the Angola LNG Carriers, which are commercially and technically managed by NYK Energy Transport (Atlantic) Ltd. Safety and environmental compliance are our top operational


priorities. We operate our vessels in a manner intended to protect the safety and health of the employees, the general public and the environment. We seek to manage the risks inherent in our business and are committed to eliminating incidents that threaten the safety and integrity of our vessels, such as groundings, fires, collisions and petroleumoil spills. In 2007, Teekay Corporation introduced a behavior-based safety program called “Safety in Action” to further enhance the safety culture in our fleet. We are also committed to reducing our emissions and waste generation. In 2008, Teekay Corporation introduced the Quality Assurance and Training Officers (or QATO) program to conduct rigorous internal audits of our processes and provide the seafarers with onboard training. In 2010, Teekay Corporation introduced a trainingsafety leadership program for our employees titled “Operational Leadership, The Journey” which sets out Teekay Corporation's operational expectations, the responsibilities of individual employees and our commitment to empowering our employees to work safely and live Teekay Corporation’s vision through a positive and responsible attitude.

Key performance indicators facilitate regular monitoring of our operational performance. Targets are set on an annual basis to drive continuous improvement, and indicators are reviewed monthly to determine if remedial action is necessary to reach the targets.

Teekay Corporation has achieved certification under the standards reflected in International Standards Organization’s (or ISO) 9001 for Quality Assurance, ISO 14001 for Environment Management Systems, Occupational Health and Safety Advisory Services 18001 for Occupational Health and Safety, and the IMO’s International Management Code for the Safe Operation of Ships and Pollution Prevention (or ISM Code) on a fully integrated basis. As part of Teekay Corporation’s compliance with the ISM Code, all of our vessels’ safety management certificates are maintained through ongoing internal audits performed by our certified internal auditors and intermediate external audits performed by the classification society DNV-GL. Subject to satisfactory completion of these internal and external audits, certification is valid for five years.


In addition to our operational experience, Teekay Corporation’s in-house global shore staff performs, through its subsidiaries, the full range of technical, commercial and business development services for our LNG, LPG and conventional operations. ThisThe staff also provides administrative support to our operations in finance, accounting and human resources. We believe this arrangement affords a safe, efficient and cost-effective operation. Vessel management services are provided by subsidiaries of Teekay Corporation, located in various offices around the world. These include critical vessel management functions such as:

vessel maintenance (including repairs and dry docking) and certification;
crewing by competent seafarers;
procurement of stores, bunkers and spare parts;
management of emergencies and incidents;
supervision of shipyard and projects during construction of newbuildings and conversions;
insurance; and
financial management services.

These functions are supported by onboard and onshore systems for maintenance, inventory, purchasing and budget management.

In addition, Teekay Corporation’s day-to-day focus on cost control is applied to our operations. In 2003, Teekay Corporation and two other shipping companies established a purchasing cooperation agreement called the TBW Alliance, which leverages the purchasing power of the combined fleets, mainly in such commodity areas as marine lubricants, coatings and chemicals and gases. Through our arrangements with Teekay Corporation, we benefit from this purchasing alliance.



We believe that the generally uniform design of some of our existing and newbuilding vessels and the adoption of common equipment standards provide operational efficiencies, including with respect to crew training and vessel management, equipment operation and repair, and spare parts ordering.
Risk of Loss, Insurance and Risk Management
The operation of any ocean-going vessel carries an inherent risk of catastrophic marine disasters, death or injury of persons and property losses caused by adverse weather conditions, mechanical failures, human error, war, terrorism, piracy and other circumstances or events. In addition, the transportation and transfer/lightering of crude oil, petroleum products, LNG and LPG are subject to the risk of spills and to business interruptions due to political circumstances in foreign countries, hostilities, labor strikes, sanctions and boycotts. The occurrence of any of these events may result in loss of revenues or increased costs.

We carry hull and machinery (marine and war risks) and protection and indemnity insurance coverage to protect against most of the accident-related risks involved in the conduct of our business. Hull and machinery insurance covers loss of or damage to a vessel due to marine perils such as collision, grounding and weather. Protection and indemnity insurance indemnifies us against liabilities incurred while operating vessels, including injury to our crew or third parties, cargo loss and pollution. The current maximum amount of our coverage for pollution is $1 billion per vessel per incident. We also carry insurance policies covering war risks (including piracy and terrorism) and, for some of our LNG carriers, loss of revenues resulting from vessel off-hire time due to a marine casualty.

We believe that our current insurance coverage is adequate to protect against most of the accident-related risks involved in the conduct of our business and that we maintain appropriate levels of environmental damage and pollution insurance coverage. However, we cannot guarantee that all covered risks are adequately insured against, that any particular claim will be paid or that we will be able to procure adequate insurance coverage at commercially reasonable rates in the


future. More stringent environmental regulations have resulted in increased costs for, and may result in the lack of availability of, insurance against risks of environmental damage or pollution.

In our operations, we use Teekay Corporation’s thorough risk management program that includes, among other things, risk analysis tools, maintenance and assessment programs, a seafarersseafarers' competence training program, seafarersseafarers' workshops and membership in emergency response organizations. We believe that we benefit from Teekay Corporation’s commitment to safety and environmental protection because certain of its subsidiaries assist us in managing our vessel operations.
Flag, Classification, Audits and Inspections
Our vessels are registered with reputable flag states, and the hull and machinery of all of our vessels have been “Classed” by one of the major classification societies and members of International Association of Classification Societies Ltd. (or IACS): Bureau Veritas (or BV), Lloyd’s Register of Shipping, the American Bureau of Shipping or DNV-GL.

The applicable classification society certifies that the vessel’s design and build conforms to the applicable Class rules and meets the requirements of the applicable rules and regulations of the country of registry of the vessel and the international conventions to which that country is a signatory. The classification society also verifies throughout the vessel’s life that it continues to be maintained in accordance with those rules. In order to validate this, the vessels are surveyed by the classification society, in accordance to the classification society rules, which in the case of our vessels follows a comprehensive five-year special survey cycle, renewed every fifth year. During each five-year period the vessel undergoes annual and intermediate surveys, the scrutiny and intensity of which is primarily dictated by the age of the vessel. As our vessels are modern and we have enhanced the resiliency of the underwater coatings of each vessel hull and marked the hull to facilitate underwater inspections by divers, their underwater areas are inspected in a dry-dock at five-year intervals. In-water inspection is carried out during the second or third annual inspection (i.e.(e.g. during an Intermediate Survey).

In addition to class surveys, the vessel’s flag state also verifies the condition of the vessel during annual flag state inspections, either independently or by additional authorization to class. Also, port state authorities of a vessel’s port of call are authorized under international conventions to undertake regular and spot checks of vessels visiting their jurisdiction.

Processes followed onboard are audited by either the flag state or classification society acting on behalf of the flag state to ensure that they meet the requirements of the ISM Code. We also follow an internal process of internal audits undertaken annually at each office and vessel.

We follow a comprehensive inspections and audit regime supported by our sea staff, shore-based operational and technical specialists and members of our QATO program. We carry out two internal inspections and one internal audit annually, which helps ensure us that:

our vessels and operations adhere to our operating standards;
the structural integrity of the vessel is being maintained;
machinery and equipment is being maintained to give reliable service;
we are optimizing performance in terms of speed and fuel consumption; and
our vessel’s appearance supports our brand and meets customer expectations.



Our customers also often carry out vetting inspections under the Ship Inspection Report Program, which is a significant safety initiative introduced by the Oil Companies International Marine Forum to specifically address concerns about sub-standard vessels. The inspection results permit charterers to screen a vessel to ensure that it meets their general and specific risk-based shipping requirements.

We believe that the heightened environmental and quality concerns of insurance underwriters, regulators and charterers will generally lead to greater scrutiny, inspection and safety requirements on all vessels in the oil tanker, LNG and LPG carrier markets and will accelerate the scrapping or phasing out of older vessels throughout these markets.

Overall, we believe that our relatively new, well-maintained and high-quality vessels provide us with a competitive advantage in the current environment of increasing regulation and customer emphasis on quality of service.
Regulations
General
Our business and the operation of our vessels are significantly affected by international conventions and national, state and local laws and regulations in the jurisdictions in which our vessels operate, as well as in the country or countries of their registration. Because these conventions, laws and regulations change frequently, we cannot predict the ultimate cost of compliance or their impact on the resale price or useful life of our vessels. Additional conventions, laws, and regulations may be adopted that could limit our ability to do business or increase the cost of our doing business and that may materially affect our operations. We are required by various governmental and quasi-governmental agencies to obtain permits, licenses and certificates with respect to our operations. Subject to the discussion below and to the fact that the kinds of permits, licenses and certificates required for the operations of the vessels we own will depend on a number of factors, we believe that we will be able to continue to obtain all permits, licenses and certificates material to the conduct of our operations.


International Maritime Organization (or IMO)
The IMO is the United Nations’ agency for maritime safety and prevention of pollution. IMO regulations relating to pollution prevention for oil tankers have been adopted by many of the jurisdictions in which our tanker fleet operates. Under IMO regulations and subject to limited exceptions, a tanker must be of double-hull construction in accordance with the requirements set out in these regulations, or be of another approved design ensuring the same level of protection against oil pollution. All of our tankers are double hulled.double-hulled.

Many countries, but not the United States, have ratified and follow the liability regime adopted by the IMO and set out in the International Convention on Civil Liability for Oil Pollution Damage, 1969, as amended (or CLC). Under this convention, a vessel’s registered owner is strictly liable for pollution damage caused in the territorial waters of a contracting state by discharge of persistent oil (e.g. crude oil, fuel oil, heavy diesel oil or lubricating oil), subject to certain defenses. The right to limit liability to specified amounts that are periodically revised is forfeited under the CLC when the spill is caused by the owner’s actual fault or when the spill is caused by the owner’s intentional or reckless conduct. Vessels trading to contracting states must provide evidence of insurance covering the limited liability of the owner. In jurisdictions where the CLC has not been adopted, various legislative regimes or common law governs, and liability is imposed either on the basis of fault or in a manner similar to the CLC.

IMO regulations also include the International Convention for Safety of Life at Sea (or SOLAS), including amendments to SOLAS implementing the International Ship and Port Facility Security Code (or ISPS), the ISM Code, the International Convention on Load Lines of 1966, and, specifically with respect to LNG and LPG carriers, the International Code for Construction and Equipment of Ships Carrying Liquefied Gases in Bulk (the IGC Code). SOLAS provides rules for the construction of and the equipment required for commercial vessels and includes regulations for their safe operation. Flag states which have ratified the convention and the treaty generally employ the classification societies, which have incorporated SOLAS requirements into their class rules, to undertake surveys to confirm compliance.

SOLAS and other IMO regulations concerning safety, including those relating to treaties on training of shipboard personnel, lifesaving appliances, radio equipment and the global maritime distress and safety system, are applicable to our operations. Non-compliance with IMO regulations, including SOLAS, the ISM Code, ISPS and the IGC Code, may subject us to increased liability or penalties, may lead to decreases in available insurance coverage for affected vessels and may result in the denial of access to or detention in some ports. For example, the United States Coast Guard (or Coast GuardUSCG) and European Union authorities have indicated that vessels not in compliance with the ISM Code will be prohibited from trading in U.S. and European Union ports. The ISM Code requires vessel operators to obtain a safety management certification for each vessel they manage, evidencing the ship owner’s development and maintenance of an extensive safety management system. Each of the existing vessels in our fleet is currently ISM Code-certified, and we expect to obtain safety management certificates for each newbuilding vessel upon delivery.

LNG and LPG carriers are also subject to regulation under the IGC Code. Each LNG and LPG carrier must obtain a certificate of compliance evidencing that it meets the requirements of the IGC Code, including requirements relating to its design and construction. Each of our LNG and LPG carriers is currently IGC Code compliant, and each of the shipbuilding contracts for our LNG carrier newbuildings and for the LPG carrier newbuildings requires IGC Code compliance prior to delivery. A revised and updatedAmendments to the IGC Code, which takes account of advancesaligning wheelhouse window fire-rating requirements with those in scienceSOLAS chapter II-2, were adopted in 2016 and technology, was adopted by the IMO’s Maritime Safety Committee (or MSC) on May 22, 2014 and enteredare expected to enter into force on January 1, 2016 with an implementation/application date of July 1, 2016.2020.

In addition, the IMO’s MSC has adopted the International Code of Safety for Ships using Gases or other Low-flashpoint Fuels (or the IGF Code), which entered into force on January 1, 2017, is mandatory for ships fueled by gases or other low-flashpoint fuels, settingand sets out mandatory provisions for the arrangement, installation, control and monitoring of machinery, equipment and systems using low-flashpoint fuel.



Annex VI of the IMO’s International Convention for the Prevention of Pollution from Ships (or MARPOL) (or Annex VI) sets limits on sulfur oxide and nitrogen oxide (or NOx) emissions from ship exhausts and prohibits emissions of ozone depleting substances, emissions of volatile compounds from cargo tanks and the incineration of specific substances. Annex VI also includes a world-wide cap on the sulfur content of fuel oil and allows for special "emission control areas" (or ECAs) to be established with more stringent controls on sulfur emissions.

Annex VI provides for a three-tier reduction in NOx emissions from marine diesel engines, with the final tier (or Tier III) to apply to engines installed on vessels constructed on or after January 1, 2016 and which operate in the North American ECA or the U.S. Caribbean Sea ECA as well as ECAs designated in the future by the IMO. In October 2016 the IMO’s Marine Environment Protection Committee (or MEPC) approved the designation of the North Sea (including the English Channel) and the Baltic Sea as ECAs for NOx emissions; these ECAs and the related amendments to Annex VI of MARPOL (with some exceptions) shall enterentered into effect on January 1, 2019. This requirement will be applicable for new ships constructed on or after January 1, 2021 if they visit the Baltic or North Sea (including the English Channel) and requires the future trading area of a ship to be assessed at the contract stage. There are exemption provisions to allow ships with only Tier II engines, to navigate in a NOx Tier III ECA if the ship is departing from a shipyard where the ship is newly built or visiting a shipyard for conversion/repair/maintenance without loading/unloading cargoes.

Effective January 1, 2020, Annex VI imposes a global limit for sulphur in fuel oil used on board ships of 0.50% m/m (mass by mass), regardless of whether a ship is operating outside a designated ECA. To comply with this new standard, ships may utilize different fuels containing low or zero sulphur (e.g. LNG or biofuels), or utilize exhaust gas cleaning systems, known as “scrubbers.” Amendments to the information to be included in bunker delivery notes relating to the supply of marine fuel oil to ships fitted with alternative mechanisms to address sulphur emission requirements (e.g. scrubbers) became effective January 1, 2019. At present, we have not installed any scrubbers on our existing fleet and we intend to switch over to burning low sulphur fuel from January 1, 2020.
As of March 1, 2018, amendments to Annex VI impose new requirements on ships of 5,000 gross tonnage and above to collect fuel oil consumption data for each type of fuel oil they use,ships, as well as certain other data including proxies for transport work.work; the amendments also set forth criteria for determining whether cargo residues are harmful to the marine environment and a new Garbage Record Book format

IMO regulations requirerequired that, as of January 1, 2015, all vessels operating within ECAs worldwide recognized under MARPOL Annex VI must comply with 0.1% sulfur requirements. Currently, the only grade of fuel meeting this low sulfur content requirement is 0.1% sulfur marine gas oil (or LSMGO). Certain modifications were completed on our Suezmax tankers in order to optimize operation on LSMGO of equipment originally designed to operate on Heavy Fuel Oil (or HFO), and to ensure our compliance with the EU Directive. In addition, LSMGO is more expensive than HFO and this impacts the costs of operations. Our exposure to increased cost is in our spot trading vessels, although our competitors bear a similar cost increase as this is a regulatory item applicable to all vessels. All required vessels in our fleet trading to and within regulated low sulfur areas are able to comply with fuel requirements. The global cap on the sulfur content of fuel oil is currently 3.5%, to be reduced to 0.5% by January 1, 2020.



The IMO has issued guidance regarding protecting against acts of piracy off the coast of Somalia. We comply with these guidelines.

The IMO's Ballast Water Management Convention entered into force on September 8, 2017. As of December 31, 20172018, there were 6779 contracting states to the convention. The convention stipulates two standards for discharged ballast water. The D-1 standard covers ballast water exchange while the D-2 standard covers ballast water treatment. The convention requires the implementation of either the D-1 or D-2 standard. There will be a transitional period from the entry into force to the International Oil Pollution Prevention (or IOPP) renewal survey in which ballast water exchange (reg. D-1) can be employed. The IMO’s Marine Environment Protection Committee (or MEPC) agreed to a compromise on the implementation dates for the D-2 discharge standard: ships constructed on or after September 8, 2017 must comply with the D-2 standard upon delivery. Existing ships should be D-2 compliant on the first IOPP renewal following entry into force if the survey is completed on or after September 8, 2019, or a renewal IOPP survey is completed on or after September 8, 2014 but prior to September 8, 2017. Ships should be D-2 compliant on the second IOPP renewal survey after September 8, 2017 if the first renewal survey after that date is completed prior to September 8, 2019 and if the previous two conditions are not met. Vessels will be required to meet the discharge standard D-2 by installing an approved Ballast Water Management System (or BWMS). Besides the IMO convention, ships sailing in U.S. waters are required to employ a type-approved BWMS which is compliant with USCG regulations. The USCG has approved a number of BWMS.BWMS - Alfa Laval (Sweden), Ocean Saver (Norway), Sunrui (China), Optimarin (Norway), Ecochlor (USA), Erma First (Greece), Hyundai Heavy Industries Co. Ltd. (Korea), Qingdao Headway Technology Co. Ltd. (China), and JFE Engineering Corporation (Japan), out of which first two makers are under Teekay’ s approved list for retrofit. We estimate that the installation of approved BWMS may cost between $2 million and $3 million per vessel.
Amendments to MARPOL Annex VI that makes the data collection system for fuel oil consumption of ships mandatory were adopted at the 70th session of the MEPC held in October 2016 and entered into force on March 1, 2018. The amendments require operators to update the vessels Ship Energy Efficiency Management Plan (or SEEMP) to include a part II describing the ship specific methodology that will be used for collecting and measuring data for fuel oil consumption, distance travelled, hours underway, ensuring data quality is maintained and the processes that will be used to report the data to the Administration. This must be verified as compliant on or before December 31, 2018, with the first data collection period being for the 2019 calendar year. A Confirmation of Compliance will be issued by the administration/registered organization, which must be kept on board the ship.
The IMO has also adopted an International Code for Ships Operating in Polar Waters (or Polar Code) which deals with matters regarding the design, construction, equipment, operation, search and rescue and environmental protection in relation to ships operating in waters surrounding the two poles. The Polar Code includes both safety and environmental provisions. The Polar Code and related amendments entered into force in January 2017. The Polar Code is mandatory for new vessels built after January 1, 2017. For existing ships, this code will be applicable from the first intermediate or renewal survey, whichever occurs first, beginning on or after January 1, 2018.

In addition to the requirements of major IMO shipping conventions, the exploration for and production of oil and gas within the Newfoundland & Labrador (or NL) offshore area is conducted pursuant to the Canada Newfoundland and Labrador Atlantic Accord Implementation Act (or the Accord Act) in accordance with the conditions of a license and authorization issued by the Canada-Newfoundland and Labrador Offshore Petroleum Board (or CNLOPB). Various regulations dealing with environmental, occupational health and safety, and other aspects of offshore oil and gas activities have been enacted under the Accord Act. The CNLOPB has also issued interpretive guidelines concerning compliance with the regulations, and compliance with CNLOPB guidelines may be a condition of the issuance or renewal of the license and authorizations. These regulations and guidelines require that shuttle tankers in the NL offshore area meet stringent standards for equipment, reporting and redundancy systems, and for the training and equipping of seagoing staff. Further, licensees are required by the Accord Act to provide a benefits plan satisfactory to CNLOPB. Such plans generally require the licensee to: establish an office in NL; give NL residents first consideration for training and employment; make expenditures for research and development and education and training to be carried out in NL; and give first consideration to services provided from within NL and to goods manufactured in NL. These regulatory requirements may change as regulations and CNLOPB guidelines are amended or replaced from time to time.

MARPOL Annex I also states that oil residue may be discharged directly from the sludge tank to the shore reception facility through standard discharge connections. They may also be discharged to the incinerator or to an auxiliary boiler suitable for burning the oil by means of


a dedicated discharge pump. Amendments to Annex I expand on the requirements for discharge connections and piping to ensure residues are properly disposed of. Annex I is applicable for existing vessels with a first renewal survey beginning on or after January 1, 2017.

Amendments to MARPOL Annex V were adopted at the 70th session of the MEPC held in October 2016 and entered into force on March 1, 2018. The changes include criteria for determining whether cargo residues are harmful to the marine environment and a new Garbage Record Book (or GRB) format with a new garbage category for e-waste. Solid bulk cargo as per regulation VI/1-1.2 of SOLAS, other than grain, shall now be classified as per the criteria in the new Appendix I of MARPOL Annex V, and the shipper shall then declare whether or not the cargo is harmful to the marine environment. A new form of the GRB has been included in Appendix II to MAROL Annex V. The GRB is now divided into two parts: Part I - for all garbage other than cargo residues, applicable to all ships. PART II - for cargo residues only applicable to ships carrying solid bulk cargo. These changes are reflected in the vessels latest revised GRB.

MSC 91 adopted amendments to SOLAS Regulation II-2/10 to clarify that a minimum of two-way portable radiotelephone apparatus for each fire party for fire-fighters' communication shall be carried on board. These radio devices shall be of explosion proof type or intrinsically safe type. All existing ships built before July 1, 2014 should comply with this requirement by the first safety equipment survey after July 1, 2018. All new vessels constructed (keel laid) on or after July 1, 2014 must comply with this requirement at the time of delivery. Amendments to SOLAS Regulation II-1/2/-12 on protection against noise. Regulation II-2/1 and II 2/10 on firefighting and new Regulation XI-12-1 on harmonization of survey periods of cargo ships not subject to the ESP code become effective January 1, 2020.

As per MSC. 338(91), requirements have been highlighted for audio and visual indicators for breathing apparatus which will alert the user before the volume of the air in the cylinder has been reduced to no less than 200 liters. This applies to ships constructed on or after July 1, 2014. Ships constructed before July 1, 2014 must comply no later than July 1, 2019.

Cyber-related risks are operational risks that are appropriately assessed and managed in accordance with the safety management requirements of the ISM Code. Cyber risks are required to be appropriately addressed in our safety management system no later than the first annual verification of the company's Document of Compliance after January 1, 2021.

The IMO continues to review and introduce new regulations; as such, it is impossible to predict what additional requirements, if any, may be adopted by the IMO and what effect, if any, such regulations might have on our operations.

European Union (or EU)
The EU has adopted legislation that: bans from European waters manifestly sub-standard vessels (defined as vessels that have been detained twice by EU port authorities, in the preceding two years); creates obligations on the part of EU member port states to inspect minimum percentages of vessels using these ports annually; provides for increased surveillance of vessels posing a high risk to maritime safety or the marine environment; and provides the EU with greater authority and control over classification societies, including the ability to seek to suspend or revoke the authority of negligent societies.

Two regulations, were introduced by the European Commission in September 2010, asthat are part of the implementation of the Port State Control Directive. TheseDirective, came into force on January 1, 2011 and introduce a ranking system (published on a public website and updated daily) displaying shipping companies operating in the EU with the worst safety records. The ranking is judged upon the results of the technical inspections carried out on the vessels owned be a particular shipping company. Those shipping companies that have the most positive safety records are rewarded by subjecting them to fewer inspections, while those with the most safety shortcomings or technical failings recorded upon inspection will in turn be subject to a greater frequency of official inspections to their vessels.

The EU has, by way of Directive 2005/35/EC, which has been amended by Directive 2009/123/EC, created a legal framework for imposing criminal penalties in the event of discharges of oil and other noxious substances from ships sailing in its waters, irrespective of their flag. This relates to discharges of oil or other noxious substances from vessels. Minor discharges shall not automatically be considered as


offences, except where repetition leads to deterioration in the quality of the water. The persons responsible may be subject to criminal penalties if they have acted with intent, recklessly or with serious negligence and the act of inciting, aiding and abetting a person to discharge a polluting substance may also lead to criminal penalties.

The EU has adopted a Directive requiring the use of low sulfur fuel. Since January 1, 2015, vessels have been required to burn fuel with sulfur content not exceeding 0.1% while within EU member states’ territorial seas, exclusive economic zones and pollution control zones that are included in SOX Emission Control Areas. Other jurisdictions have also adopted similar regulations. Since January 1, 2014, the California Air Resources Board has required vessels to burn fuel with 0.1% sulfur content or less within 24 nautical miles of California. China also established emission control areas and continues to establish such areas, restricting the maximum sulfur content of the fuel to be used by vessels within those areas, which limits become progressively stricter over time. Since January 1, 2017, all core ports within the three China ECAs (i.e.(e.g. Tianjin, Qinhuangdao, Tangshan, Huanghua, Shenzhen, Guangzhou, Zhuhai, Shanghai, Ningbo-Zhoushan, Suzhou and Nantong) have implemented the low sulfur bunker requirements. It is anticipated that commencing January 1, 2018 all ports within the three China ECAs will have implemented the low sulfur bunker requirements.

The EU Ship Recycling Regulation entered into force on December 30, 2013. It aims to prevent, reduce and minimize accidents, injuries and other negative effects on human health and the environment when ships are recycled and the hazardous waste they contain is removed. The legislation applies to all ships flying the flag of an EU country and to vessels with non-EU flags that call at an EU port or anchorage. It sets out responsibilities for ship owners and for recycling facilities both in the EU and in other countries. Each new ship is required to have on board an inventory of the hazardous materials (such as asbestos, lead or mercury) it contains in either its structure or equipment. The use of certain hazardous materials is forbidden. Before a ship is recycled, its owner must provide the company carrying out the work with specific information about the vessel and prepare a ship recycling plan. Recycling may only take place at facilities listed on the EU ‘List of facilities’. In 2014, the Council Decision 2014/241/EU authorized EU countries having ships flying their flag or registered


under their flag to ratify or to accede to the Hong Kong International Convention for the Safe and Environmentally Sound Recycling of Ships. The EU Ship Recycling Regulation is to apply generally not later thanentered into force on December 31, 2018, with certain provisions applicable from December 31, 2020. Compliance timelines are as follows: EU-flagged new-buildings were required to have onboard a verified Inventory of Hazardous Materials (or IHM) with a Statement of Compliance at the latest by December 31, 2018, existing EU-flagged vessels are required to have onboard a verified IHM with a Statement of Compliance at the latest by December 31, 2020, non-EU-flagged vessels calling at EU ports are also required to have onboard a verified IHM with a Statement of Compliance latest by December 31, 2020. The EU Commission adopted a European List of approved ship recycling facilities, as well as four further implementing decisions dealing with certification and other administrative requirements set out in the EU Ship Recycling Regulation.

China

China has also established ECAs in the Pearl River Delta, the Yangtze River Delta and the Bohai Sea area with restrictions limiting sulfur content not to exceed 0.5% in such ECAs, with such limit decreasing over time.

All the key ports within the three China ECAs (i.e.(e.g. Tianjin, Qinhuangdao, Tangshan, Huanghua, Shenzhen, Guangzhou, Zhuhai, Shanghai, Ningbo-Zhoushan, Suzhou and Nantong) have implemented the low sulfur bunker requirements. 

Commencing January 1, 2018, a ship’sships berthing (excluding one hour after berthing and one hour before departure) at all ports within the China ECAs are required to use fuel with sulphur contents at or below 0.5%. These limitations will applyapplied to the entire period vessels are in port within China ECAs commencingeffective January 1, 2019.

China will complete an assessment of the effectiveness of the introduced measures by the end of 2019. Based on the results of such assessment possible further enforcement of regulations limiting SOx emission in ECA’s may be implemented reducing the sulfphur content to 0.1% for ships in the ECA, extending the boundaries of the ECAs or introducing new control measures.
United States
The United States has enacted an extensive regulatory and liability regime for the protection and cleanup of the environment from oil spills, including discharges of oil cargoes, bunker fuels or lubricants, primarily through the Oil Pollution Act of 1990 (or OPA 90) and the Comprehensive Environmental Response, Compensation and Liability Act (or CERCLA). OPA 90 affects all owners, bareboat charterers, and operators whose vessels trade to the United States or its territories or possessions or whose vessels operate in United States waters, which include the U.S. territorial sea and 200-mile exclusive economic zone around the United States. CERCLA applies to the discharge of “hazardous substances” rather than “oil” and imposes strict joint and several liability upon the owners, operators or bareboat charterers of vessels for cleanup costs and damages arising from discharges of hazardous substances. We believe that petroleum products, LNG and LPG should not be considered hazardous substances under CERCLA, but additives to oil or lubricants used on LNG or LPG carriers might fall within its scope.

Under OPA 90, vessel owners, operators and bareboat charters are “responsible parties” and are jointly, severally and strictly liable (unless the oil spill results solely from the act or omission of a third party, an act of God or an act of war and the responsible party reports the incident and reasonably cooperates with the appropriate authorities) for all containment and cleanup costs and other damages arising from discharges or threatened discharges of oil from their vessels. These other damages are defined broadly to include:

natural resources damages and the related assessment costs;
real and personal property damages;
net loss of taxes, royalties, rents, fees and other lost revenues;
lost profits or impairment of earning capacity due to property or natural resources damage;
net cost of public services necessitated by a spill response, such as protection from fire, safety or health hazards; and
loss of subsistence use of natural resources.



OPA 90 limits the liability of responsible parties in an amount it periodically updates. The liability limits do not apply if the incident was proximately caused by violation of applicable U.S. federal safety, construction or operating regulations, including IMO conventions to which the United States is a signatory, or by the responsible party’s gross negligence or willful misconduct, or if the responsible party fails or refuses to report the incident or to cooperate and assist in connection with the oil removal activities. Liability under CERCLA is also subject to limits unless the incident is caused by gross negligence, willful misconduct or a violation of certain regulations. We currently maintain for each of our vessels pollution liability coverage in the maximum coverage amount of $1 billion per incident. A catastrophic spill could exceed the coverage available, which could harm our business, financial condition and results of operations.

Under OPA 90, with limited exceptions, all newly built or converted tankers delivered after January 1, 1994 and operating in U.S. waters must be double-hulled. All of our tankers are double-hulled.

OPA 90 also requires owners and operators of vessels to establish and maintain with the Coast GuardUSCG evidence of financial responsibility in an amount at least equal to the relevant limitation amount for such vessels under the statute. The Coast GuardUSCG has implemented regulations requiring that an owner or operator of a fleet of vessels must demonstrate evidence of financial responsibility in an amount sufficient to cover the vessel in the fleet having the greatest maximum limited liability under OPA 90 and CERCLA. Evidence of financial responsibility may be demonstrated by insurance, surety bond, self-insurance, guaranty or an alternate method subject to approval by the Coast Guard.USCG. Under the self-insurance provisions, the shipowner or operator must have a net worth and working capital, measured in assets located in the


United States against liabilities located anywhere in the world, that exceeds the applicable amount of financial responsibility. We have complied with the Coast GuardUSCG regulations by using self-insurance for certain vessels and obtaining financial guaranties from a third party for the remaining vessels. If other vessels in our fleet trade into the United States in the future, we expect to obtain guaranties from third-party insurers.

OPA 90 and CERCLA permit individual U.S. states to impose their own liability regimes with regard to oil or hazardous substance pollution incidents occurring within their boundaries, and some states have enacted legislation providing for unlimited strict liability for spills. Several coastal states, such as California and Alaska, require state-specific evidence of financial responsibility and vessel response plans. We intend to comply with all applicable state regulations in the ports where our vessels call.

Owners or operators of vessels, including tankers operating in U.S. waters, are required to file vessel response plans with the Coast Guard,USCG, and their tankers are required to operate in compliance with their Coast GuardUSCG approved plans. Such response plans must, among other things:

address a “worst case” scenario and identify and ensure, through contract or other approved means, the availability of necessary private response resources to respond to a “worst case discharge”;
describe crew training and drills; and
identify a qualified individual with full authority to implement removal actions.

WeAll our vessels have filedUSCG approved vessel response plans with the Coast Guard and have received its approval of such plans. In addition, we conduct regular oil spill response drills in accordance with the guidelines set out in OPA 90. The Coast GuardUSCG has announced it intends to propose similar regulations requiring certain vessels to prepare response plans for the release of hazardous substances.

OPA 90 and CERCLA do not preclude claimants from seeking damages resulting from the discharge of oil and hazardous substances under other applicable law, including maritime tort law. Such claims could include attempts to characterize the transportation of LNG or LPG aboard a vessel as an ultra-hazardous activity under a doctrine that would impose strict liability for damages resulting from that activity. The application of this doctrine varies by jurisdiction.

The U.S. Clean Water Act (or the Clean Water Act) also prohibits the discharge of oil or hazardous substances in U.S. navigable waters and imposes strict liability in the form of penalties for unauthorized discharges. The Clean Water Act imposes substantial liability for the costs of removal, remediation and damages and complements the remedies available under OPA 90 and CERCLA discussed above.

Our vessels that discharge certain effluents, including ballast water, in U.S. waters must obtain a Clean Water Act permit from the Environmental Protection Agency (or EPA) titled the “Vessel General Permit” and comply with a range of effluent limitations, best management practices, reporting, inspections and other requirements. The current Vessel General Permit incorporates Coast Guardincorporated USCG requirements for ballast water exchange and includes specific technology-based requirements for vessels, and includes an implementation schedule to require vessels to meet the ballast water effluent limitations by the first drydockingdry docking after January 1, 2014 or January 1, 2016, depending on the vessel size. This permit is effectiveThe Vessel Incidental Discharge Act (or VIDA) was signed into law on December 4, 2018 and establishes a new framework for the regulation of vessel incidental discharges under the Clean Water Act. VIDA requires the U.S. EPA to December 18, 2018.develop performance standards for incidental discharges and requires the USCG to develop regulations within two years of the EPA’s promulgation of standards. Under VIDA, all provisions of the Vessel General Permit remain in force and effect as currently written until the USCG regulations are finalized. Vessels that are constructed after December 1, 2013 are subject to the ballast water numeric effluent limitations immediately upon the effective date of the 2013 Vessel General Permit.limitations. Several U.S. states have added specific requirements to the Vessel General Permit and, in some cases, may require vessels to install ballast water treatment technology to meet biological performance standards.

Various states in the United States, including California, have implemented additional regulations relating to the environment and operation of vessels. California Biofouling Management Plan requirements are as follows: developing and maintaining a Biofouling Management Plan, developing and maintaining a Biofouling Record Book, mandatory biofouling management of the vessel’s wetted surfaces, mandatory biofouling management for vessels that undergo an extended residency period (i.e.(e.g. remain in the same location for 45 or more days). All vessel calling at California water were required to submit the "Annual Marine Invasive Reporting Form" by October 1, 2017 and should have CA-Biofouling management plan after a vessel’s first regularly scheduled out-of-water maintenance (i.e.(e.g. dry dock) after January 1, 2018, or upon delivery on or after January 1, 2018.


New Zealand
New Zealand's Craft Risk Management Standard (or CRMS) requirements are based on the IMO's guidelines for the control and management of ships' biofouling to minimize the transfer of invasive aquatic species.
Marine pests and diseases brought in on vessel hulls (or biofouling) are a threat to New Zealand's marine resources. From May 15, 2018, all vessels arriving in New Zealand will need to have a clean hull. Vessels staying up to 20 days and only visiting designated ports (places of first arrival) will be allowed a slight amount of biofouling. Vessels staying longer and visiting other places will only be allowed a slime layer and goose barnacles.
Greenhouse Gas Regulation
In February 2005, the Kyoto Protocol to the United Nations Framework Convention on Climate Change (or the Kyoto Protocol) took effect. Pursuant to the Kyoto Protocol, adopting countries are required to implement national programs to reduce emissions of greenhouse gases. In December 2009, more than 27 nations, including the United States, entered into the Copenhagen Accord. The Copenhagen Accord is


non-binding but is intended to pave the way for a comprehensive, international treaty on climate change. In December 2015 the Paris Agreement (or the Paris Agreement) was adopted by a large number of countries at the 21st Session of the Conference of Parties (commonly known as COP 21, a conference of the countries which are parties to the United Nations Framework Convention on Climate Change; the COP is the highest decision-making authority of this organization). The Paris Agreement, which entered into force on November 4, 2016, deals with greenhouse gas emission reduction measures and targets from 2020 in order to limit the global temperature increases to well below 2o Celsius above pre-industrial levels. Although shipping was ultimately not included in the Paris Agreement, it is expected that the adoption of the Paris Agreement may lead to regulatory changes in relation to curbing greenhouse gas emissions from shipping.

In July 2011, the IMO adopted regulations imposing technical and operational measures for the reduction of greenhouse gas emissions. These new regulations formed a new chapter in Annex VI and became effective on January 1, 2013. The new technical and operational measures imposed by these new regulations include the “Energy Efficiency Design Index” (or the EEDI), which is mandatory for newbuilding vessels, and the “Ship Energy Efficiency Management Plan,” which is mandatory for all vessels. In October 2016, the IMO’s MEPC adopted updated guidelines for the calculation of the EEDI. In addition, the IMO is evaluating various mandatory measures to reduce greenhouse gas emissions from international shipping, which may include market-based instruments or a carbon tax. In October 2014, the IMO’s MEPC agreed in principle to develop a system of data collection regarding fuel consumption of ships. In October 2016, the IMO adopted a mandatory data collection system under which vessels of 5,000 gross tonnage and above are to collect fuel consumption and other data and to report the aggregated data so collected to their flag state at the end of each calendar year. The new requirements entered into force on March 1, 2018. All vessels are required to submit fuel consumption data to their respective administration/registered organizations for onward submission to the IMO for analysis and to help with decision making on future measures. The amendments require operators to update the vessels SEEMP to include a part II describing the ship specific methodology that will be used for collecting and measuring data for fuel oil consumption, distance travelled, hours underway and processes that will be used to report the data to the Administration, in order to ensure data quality is maintained. The vessels were required to be verified as compliant on or before December 31, 2018, with the first data collection period being for the 2019 calendar year. A Confirmation of Compliance will be issued by the administration/registered organization, which must be kept on board the ship. The IMO also approved a roadmap for the development of a comprehensive IMO strategy on reduction of greenhouse gas emissions from ships with an initial strategy to be adopted inon April 13, 2018 (July 7, 2017 saw the MEPC agree on a draft outline of the IMO’s strategy for reducing greenhouse gas emissions in the shipping sector) and a revised strategy to be adopted in 2023.2023.

The EU also has indicated that it intends to propose an expansion of an existing EU emissions trading regime to include emissions of greenhouse gases from vessels, and individual countries in the EU may impose additional requirements. The EU has adopted Regulation (EU) 2015/757 on the monitoring, reporting and verification of carbon dioxide (or CO2MRV) of CO2 emissions from vessels (or the MRV Regulation), which entered into force on July 1, 2015. The regulationMRV Regulation aims to quantify and reduce CO2 emissions from shipping. It lists the requirements on monitoring, reporting and verification (or the MRV) of carbon dioxide emissions and requires ship owners and operators to annually monitor, report and verify CO2 emissions for vessels larger than 5,000 gross tonnage calling at any EU and EFTA (Norway and Iceland) port (with a few exceptions, such as fish-catching or fish-processing vessels). Data collection takes place on a per voyage basis and startsstarted January 1, 2018. The reported CO2 emissions, together with additional data, such as cargo and energy efficiency parameters, are to be verified by independent verifiers and sent to a central inspection database managedhosted by the European Maritime Safety Agency. To comply withAgency (or EMSA) to collate all the data applicable to the EU MRV regulation, Teekay Corporation has prepared anregion. Companies responsible for the operation of large ships using EU MRV monitoring plan and EU MRV monitoring template in line with legislative requirement.ports are required to report their CO2 emissions. While the EU was considering a proposal for the inclusion of shipping in the EU Emissions Trading System as from 2021 (in the absence of a comparable system operating under the IMO), it appears that the decision to include shipping may be deferred until 2023.2023

.
In the United States, the EPA issued an “endangerment finding” regarding greenhouse gases under the U.S. Clean Air Act. While this finding in itself does not impose any requirements on our industry, it authorizes the EPA to regulate directly greenhouse gas emissions through a rule-making process. In addition, climate change initiatives are being considered in the United States Congress and by individual states. Any passage of new climate control legislation or other regulatory initiatives by the IMO, EU, the United States or other countries or states where we operate that restrict emissions of greenhouse gases could have a significant financial and operational impact on our business that we cannot predict with certainty at this time.
Vessel Security
The ISPS was adopted by the IMO in December 2002 in the wake of heightened concern over worldwide terrorism and became effective on July 1, 2004. The objective of ISPS is to enhance maritime security by detecting security threats to ships and ports and by requiring the development of security plans and other measures designed to prevent such threats. Each of the existing vessels in our fleet currently complies with the requirements of ISPS and Maritime Transportation Security Act of 2002 (U.S. specific requirements). Procedures are in place to inform the relevant reporting regimes such as Maritime Security Council Horn of Africa (or MSCHOA), the Maritime Domain Awareness for Trade - Gulf of Guinea (or MDAT-GoG), the Information Fusion Center (or IFC) whenever our vessels are calling in the Indian Ocean Region, or West Coast of Africa (or WAC) or SE Asia high risk areas respectively. In order to mitigate the security risk, security arrangements are required for vessels which travel through these high risk areas.

E.Taxation of the Partnership
The expected material U.S federal income tax considerations applicable to us changed significantly effective as of January 1, 2019, due to our election to be taxed as a corporation, rather than as a partnership, for U.S. federal income tax purposes.  The discussion included herein is with regard to the material U.S. federal income tax considerations that may be relevant to us and our unitholders in 2019 and future years. For a discussion on material U.S. federal income tax considerations during 2018 that may have been relevant to us and our unitholders who were individual citizens or residents of the United States, please read “Item 10. Additional Information – Taxation-United States Tax Consequences” in our Annual Report on Form 20-F for the year ended December 31, 2017.
United States Taxation

The following is a discussion of the expected material U.S. federal income tax considerations applicable to us effective January 1, 2019. This discussion is based upon the provisions of the Code, legislative history, applicable U.S. Treasury Regulations (or Treasury Regulations), judicial authority and administrative interpretations, all as in effect on the date of this Annual Report, and which are subject to change, possibly with retroactive effect, or are subject to different interpretations. Changes in these authorities may cause the tax consequences to vary substantially from the consequences described below.

Election to be Taxed as a Corporation. We have elected to be taxed as a corporation for U.S. federal income tax purposes effective January 1, 2019. As such, we are subject to U.S. federal income tax on our income to the extent it is from U.S. sources or otherwise is effectively connected with the conduct of a trade or business in the United States as discussed below.
Taxation of Operating Income. We expect that substantially all of our gross income and the gross income of our corporate subsidiaries will be attributable to the transportation of LNG, LPG, ammonia, crude oil and related products. For this purpose, gross income attributable to transportation (or Transportation Income) includes income derived from, or in connection with, the use (or hiring or leasing for use) of a vessel to transport cargo, or the performance of services directly related to the use of any vessel to transport cargo, and thus includes both time-charter and bareboat charter income.

Fifty percent (50%) of Transportation Income that either begins or ends, but that does not both begin and end, in the United States (or U.S. Source International Transportation Income) is considered to be derived from sources within the United States. Transportation Income that both begins and ends in the United States (or U.S. Source Domestic Transportation Income) is considered to be 100% derived from sources within the United States. Transportation Income exclusively between non-U.S. destinations is considered to be 100% derived from sources outside the United States. Transportation Income derived from sources outside the United States generally is not subject to U.S. federal income tax.

Based on our current operations and the operations of our subsidiaries, we expect most of our Transportation Income to be from sources outside the United States and not subject to U.S. federal income tax. However, we have earned over $64.5 million of U.S. Source International Transportation Income annually, and we expect that we will continue to earn an increasing amount of such income in future years. Our U.S. Source International Transportation Income or U.S. Source Domestic Transportation Income is subject to U.S. federal income taxation under either the net basis and branch profits taxes or the 4% gross basis tax, each of which is discussed below, unless the exemption from U.S. taxation under Section 883 of the Code (or the Section 883 Exemption) applies.

The Section 883 Exemption. In general, the Section 883 Exemption provides that if a non-U.S. corporation satisfies the requirements of Section 883 of the Code and the Treasury Regulations thereunder, it will not be subject to the net basis and branch profits taxes or the 4% gross basis tax described below on its U.S. Source International Transportation Income. The Section 883 Exemption does not apply to U.S. Source Domestic Transportation Income.

We do not believe that we will be able to qualify for the Section 883 Exemption and therefore our U.S. Source International Transportation Income will not be exempt from U.S. federal income taxation.

Net Basis Tax and Branch Profits Tax. If the Section 883 Exemption does not apply, our U.S. Source International Transportation Income may be treated as effectively connected with the conduct of a trade or business in the United States (or Effectively Connected Income) if we have a fixed place of business in the United States and substantially all of our U.S. Source International Transportation Income is attributable to regularly scheduled transportation or, in the case of income derived from bareboat charters, is attributable to a fixed place of business in the United States. Based on our current operations, none of our potential U.S. Source International Transportation Income is attributable to regularly scheduled transportation or is derived from bareboat charters attributable to a fixed place of business in the United States. As a result, we do not anticipate that any of our U.S. Source International Transportation Income will be treated as Effectively Connected Income. However, there is no assurance that we will not earn income pursuant to regularly scheduled transportation or bareboat charters attributable to a fixed place of business in the United States in the future, which will result in such income being treated as Effectively Connected Income. U.S. Source Domestic Transportation Income generally will be treated as Effectively Connected Income. However, we do not anticipate that a material amount of our income has been, or will be, U.S. Source Domestic Transportation Income.



Any income we earn that is treated as Effectively Connected Income would be subject to U.S. federal corporate income tax (the statutory rate for 2018 onwards is 21%) and a 30% branch profits tax imposed under Section 884 of the Code. In addition, a branch interest tax could be imposed on certain interest paid or deemed paid by us.

On the sale of a vessel that has produced Effectively Connected Income, we generally would be subject to the net basis and branch profits taxes with respect to our gain recognized up to the amount of certain prior deductions for depreciation that reduced Effectively Connected Income. Otherwise, we would not be subject to U.S. federal income tax with respect to gain realized on sale of a vessel, provided the sale is considered to occur outside of the United States under U.S. federal income tax principles.

The 4% Gross Basis Tax. We believe we were not subject to the 4% Gross Basis Tax in 2018 because we were treated as a parthership for U.S. tax purposes in 2018. If the Section 883 Exemption does not apply in 2019 and future years when we are treated as a corporation for U.S. tax purposes and we are not subject to the net basis and branch profits taxes described above, we will be subject to a 4% U.S. federal income tax on our gross U.S. Source International Transportation Income, without benefit of deductions. If we had been treated as a corporation in 2018, we estimate that, in this event, we would have been subject to less than $1.4 million of U.S. federal income tax based on the amount of U.S. Source International Transportation Income we earned for 2018. We expect the amount of our liability for U.S. federal income tax on our U.S. Source International Transportation Income to increase in 2019 and subsequent years, based on our expected U.S. Source International Transportation Income. The amount of such tax for which we are liable in any year will depend upon the amount of income we earn from voyages into or out of the United States in such year, however, which is not within our complete control.
Marshall Islands Taxation

Because we and our controlled affiliates do not, and we do not expect that we and our controlled affiliates will, conduct business, operations, or transactions in the Republic of the Marshall Islands, neither we nor our controlled affiliates are subject to income, capital gains, profits or other taxation under current Marshall Islands law, other than taxes, fines, or fees due to (i) the incorporation, dissolution, continued existence, merger, domestication (or similar concepts) of legal entities registered in the Republic of the Marshall Islands, (ii) filing certificates (such as certificates of incumbency, merger, or redomiciliation) with the Marshall Islands registrar, (iii) obtaining certificates of good standing from, or certified copies of documents filed with, the Marshall Islands registrar, (iv) compliance with Marshall Islands law concerning vessel ownership, such as tonnage tax, or (v) non-compliance with requests made by the Marshall Islands registrar of corporations relating to our books and records and the books and records of our subsidiaries. As a result, distributions by controlled affiliates to us are not subject to Marshall Islands taxation.
Other Taxation

We and our subsidiaries are subject to taxation in certain non-U.S. jurisdictions because we or our subsidiaries are either organized, or conduct business or operations, in such jurisdictions, but we do not expect any such tax to be material. However, we cannot assure this result as tax laws in these or other jurisdictions may change, or we may enter into new business transactions relating to such jurisdictions, which could affect our tax liability. Please read “Item 18 – Financial Statements: Note 11 – Income Tax.”

SIGNIFICANT DEVELOPMENTS IN 20172018 AND EARLY 20182019
Preferred Unit IssuanceQuarterly Distributions


On October 23, 2017,We intend to increase our quarterly cash distributions on our common units by 36% in 2019, commencing with the distribution for the quarter ended March 31, 2019, as part of a balanced capital allocation strategy. Any increase in the level of quarterly distributions is subject to approval by the board of directors of our general partner (or Board of Directors).

Common Unit Repurchase Program

In December 2018, we issued 6.8announced that our Board of Directors had authorized a common unit repurchase program of up to $100 million of our Series B Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units (or Series B Preferred Units) (includingcommon units. Common units may be repurchased in the open market or privately-negotiated transactions or otherwise at times and prices considered appropriate by us. The timing of any purchases and the exact number of common units to be purchased under the common unit repurchase program will be dependent on market conditions and other factors.

During December 2018 and January 2019, we repurchased 0.3 million and 0.8 million of our common units issued upon partial exercisefor $3.7 million and $9.3 million, respectively.

Change in Tax Structure

During the special meeting of common unitholders held on December 18, 2018, the proposal to allow us to elect to be treated as a corporation, instead of a partnership, for U.S. federal income tax purposes, and other proposals included in the related proxy statement, were approved by unitholders. As a result, effective January 1, 2019, the Partnership will be treated as a corporation for U.S. federal income tax purposes and commencing in 2019, common and preferred unitholders will receive Form 1099s instead of Schedule K-1s relating to distributions taxable as dividends. The Partnership will remain a master limited partnership, all other provisions of the underwriters' over-allotment option) at $25.00 per unitPartnership's limited partnership agreement remain in effect.

This change to our status for U.S. federal income tax purposes should not result in the Partnership recognizing a public offeringtax related gain or loss. While some investors may incur a tax gain on conversion, any gain recognized for net proceedsU.S. tax purposes is expected to result in tax benefits to investors that are expected to reduce the taxable portion of approximately $164 million. Distributions are payable oncash distributions paid by us in the Series B Preferred Units from the issuance date to October 14, 2027, at a rate of 8.5% per annum of the stated liquidation preference of $25.00 and from and after October 15, 2027, at a floating rate equal to three-month LIBOR plus a margin of 6.241%. At any time on or after October 15, 2027, we may redeem the Series B Preferred Units, in whole or in part, at a redemption price of $25.00 per unit plus all accumulated and unpaid distributions thereon to the date of redemption. We used the net proceeds from the public offering for general partnership purposes, which included debt repayments and funding installment payments on future newbuilding deliveries. The Series B Preferred Units are listed on the New York Stock Exchange.future.
LNG Carrier Newbuildings

We recognized a gain on the sale of our ownership interest of $5.6 million, after repaying outstanding debt obligations withinwhich was recorded in equity income for the joint venture.year ended December 31, 2018.

Re-chartering Activities

In March 2018, upon its scheduled redelivery to us from Teekay Corporation, we re-chartered the Polar Spirit LNG carrier to an Asian-based energy company for a period of approximately three months and then subsequently secured employment for the vessel beginning in July 2018 for nine months with a subsidiary of Petroliam Nasional Berhad (or Petronas). In addition, we secured a four-year charter contract for the Arctic Spirit LNG carrier, also with a subsidiary of Petronas, which commenced immediately upon its scheduled redelivery from Teekay Corporation to us in May 2018. In May 2018, we agreed to a six-month charter extension of the Torben Spirit LNG carrier to December 2018

with a major energy company, which was further extended for an additional three years from the six-month extension that ended in December 2018.

Teekay Nakilat Capital Lease

We own a 70% interest in the Teekay Nakilat Joint Venture, which wholly owns a subsidiary that was the lessee under three separate 30-year capital lease arrangements with a third party for three LNG carriers (or the RasGas II LNG Carriers). Under the terms of the leases, the lessor claimed tax depreciation on the capital expenditures it incurred to acquire these vessels and paid the Teekay Nakilat Joint Venture as lessee an upfront benefit of $60.9 million at the lease inception. As is typical in these leasing arrangements, tax and change of law risks were assumed by the lessee. As described in "Item 18 - Financial Statements: Note 14b - Commitments and Contingencies," during the year ended December 31, 2018, the lessor made a determination that additional rentals were due under the leases following a challenge by the UK taxing authority and the Teekay Nakilat Joint Venture paid $63 million to the lessor, at foreign exchange rates at the dates of payment, to satisfy this tax indemnification liability in full. Of this amount, $53 million was expensed in other expense in our consolidated statements of income for the year ended December 31, 2018, which was in addition to the $12.7 million tax indemnification guarantee recorded as at December 31, 2017, with the remaining difference relating to foreign currency exchange gain.

LPG Carrier Newbuildings
In March, 2017May and July 2017,2018 our 50/50 joint venture with Exmar (or the Exmar LPG Joint Venture), of which we have a 50% ownership interest, took delivery of the Kallo LPG carrier and Kruibeke LPG carrier, respectively, and upon delivery sold and leased back the vessels. In April 2017, the Exmar LPG Joint Venture entered into a shipbuilding agreement with Hyundai Heavy Industries Co., Ltd. for one additional LPG carrier newbuilding scheduled for delivery in mid-2018. As at December 31, 2017, the Exmar LPG Joint Venture had three LPG carrier newbuildings scheduled for delivery in 2018. On March 5, 2018, the-owned Exmar LPG Joint Venture, took delivery of its seventh, eighth and ninth LPG carrier newbuildingnewbuildings in the past four years, the Kapellen.,
Koksijde and Wepion, respectively. TheKapellen, Koksijde and Wepion are on short-term charter contracts. The Kapellen and Koksijde were financed through sale-leaseback financing transactions and in July 2018 the Exmar LPG Joint Venture has secured long-term vessel financing that will be available upon delivery for one of its two remaining LPG carrier newbuildings. The installment payments on the second remaining LPG carrier newbuilding are expected to be financed by the joint venture’s existing liquidity and the joint venture expects to secure long-termcompleted a three-year, $35 million debt financing for that LPG carrier prior to its delivery.the Wepion.
Conventional Tankers
In late-June 2017,February 2018 and January 2019, CEPSA, the charterer for the European Spirit Suezmax tanker gave formal notice to us that it would not exercise its one-year extension option under the charter contract and the charterer redelivered the vessel to us in late-August 2017. Upon receiving this notification, we commenced marketing the vessel for sale and recorded a $12.6 million write-downowner of the vessel during the second quarter of 2017. In addition, during the third quarter of 2017, we recorded a write-down of the AfricanSpirit of $12.5 million as we received notification from the charterer of the vessel in August 2017 that it would redeliver the vessel to us upon completion of its charter contract in November 2017. Upon the redelivery of the African Spirit, we have also commenced marketing the vessel for sale.
In August 2017, the charterer of the Teide Spirit gave formal notification to us of its intention to terminate its charter contract subject to certain conditions being met and third-party approvals being received. In October 2017, the charterer notified us that it is marketing the Teide Spirit for sale and, upon sale of the vessel, the charterer would concurrently terminate its existing charter contract with us. The charterer’s cancellation option for the Toledo Spirit is first exercisable in August 2018. Given our prior experience with this charterer, we expect the charterer will also cancel the charter contract and sell the Toledo Spirit to a third party in 2018. We recorded a write-down of $25.5 million on a combined basis related tocapital leased vessels, the Teide Spirit andToledo Spirit, for thesold these vessels to third quarter of 2017.
On February 8, 2018, CEPSA, the charterer (who is also the owner) of a vessel under capital lease, the Teide Spirit, sold the vessel to a third party.parties. As a result of this sale,these sales, we returned the vesselvessels to CEPSA and the full amount of the associated obligationobligations related to the capital lease waswere concurrently extinguished. In addition, we incurred associated seafarer severance payments in 2018 of approximately $1.4$1.8 million upon the sale of the vessel.Teide Spirit and approximately $1.8 million in 2019 for the sale of the Toledo Spirit.

On October 9, 2018, we sold the African Spirit Suezmax tanker for net proceeds of $12.8 million. On December 5, 2018, we sold the European Spirit Suezmax tanker for net proceeds of $15.7 million. During 2018, prior to the sale of these vessels, we recorded further aggregate write-downs on these two Suezmax tankers totaling $7.9 million (December 31, 2017 – $25.1 million).

Bond Issuance and Refinancings

In July 2018, we refinanced our 106.8 million Euro-denominated debt facility maturing in 2018 with a new EUR 100 million debt facility maturing in 2024, which is collateralized by a first-priority mortgage on one of our LNG carriers, the Madrid Spirit. In August 2018, we issued, in the Norwegian bond market, NOK 850 million in senior unsecured bonds that mature in August 2023. The aggregate principal amount of the bonds was equivalent to $102.0 million and all interest and principal payments have been swapped into U.S. Dollars at a fixed interest rate of 7.89%. We used the net proceeds from the bond offering to repay NOK 900 million in senior unsecured bonds that matured in September 2018 and for general corporate purposes. In November 2018, we refinanced our $190 million revolving credit facility, which was scheduled to mature in November 2018, with a new $225 million revolving credit facility maturing in November 2020 at an interest rate of LIBOR plus 1.40%. In December 2018, we refinanced our $100 million facility relating to the Bahrain Spirit FSU by completing a $109 million guaranteed private placement bond maturing in August 2030 at a fixed interest rate of 4.41%. In January 2019, we refinanced our $106 million debt facility relating to the Sean Spirit by issuing a $106 million bond maturing in December 2030 at a fixed interest rate of 4.71%.

Equity-Accounted Joint Ventures'Venture's Financings and Refinancings
On December 21, 2016, Teekay Nakilat (III) Corporation (orIn September 2018, the RasGas 3 Joint Venture), of which we have a 40% ownership interest, completed its debt refinancing by entering into a $723 million secured term loan facility maturing in 2026 and which replaced its outstanding term loan of $610 million. As a result, in February 2017 the RasGas 3 Joint Venture distributed $100 million to its shareholders, of which our proportionate share was $40 million.
On March 31, 2017, our 52% joint venture with Marubeni Corporation (or the Teekay LNG-Marubeni Joint Venture) completed the refinancing of its existing $396 million debt facility by entering into a new $335$306.5 million U.S. Dollar-denominated term loan which was scheduled to mature in September 2019 with a new $306.5 million U.S. Dollar-denominated loan agreement maturing in September 2019.December 2023 at an interest rate of LIBOR plus margins ranging from 1.00% to 2.25%. The term loan is collateralized by first-priority statutory mortgages over the Marib Spirit, Arwa Spirit, Methane Spirit and Magellan Spirit LNG carriers, first priority pledges or charges of all the issued shares of the respective vessel owning subsidiaries and is guaranteed by us and Marubeni Corporation on a several basis in proportion to our ownership. As part ofbasis. In March 2019, the completed refinancing, we invested $57 million of additional equity, based on our proportionate ownership interest, into the Teekay LNG-Marubeni Joint Venture.
On December 8, 2017, the Yamal LNGExcalibur Joint Venture completedamended its $60 million debt financing by entering into a $1.6 billion secured termfacility which extended the loan facility maturing between 2030maturity from November 2019 to December 2021 and 2032. The term loan is guaranteed by us and our joint venture partner China LNG Shipping (Holdings) Limited on a several basis in proportion to our ownership. In December 2017,lowered the Yamal LNG Joint Venture completed a drawdown on this financing and distributed $104 million to its shareholders,cost of which our proportionate share was $52 million.
Charter Contracts with Skaugen
During November 2017, we terminated the bareboat charter contracts for our six LPG carriers chartered to wholly-owned subsidiaries of I.M. Skaugen SE (or Skaugen) due to Skaugen’s breach of the charters resulting from its failure to pay us charter hire amounts owed thereunder. The six bareboat charter contracts had terms ending between 2019 and 2026. In addition, in December 2017 we withdrew the Sonoma Spirit (formerly Norgas Sonoma) from the Norgas Pool and transferred the commercial management of all seven of these LPG carriers into a newly formed in-house commercial management solution for ethylene-capable LPG and small-scale LNG vessels, the Teekay Multigas Pool, which we launched in November 2017. As at December 31, 2017, as a result of Skaugen’s breach of the six charters, Skaugen owed us an aggregate amount of approximately $25 million in unpaid hire that remain in arrears calculated based on the contracted charter rates, and such amount has not been recorded as revenue given the uncertainty of its collection. We have commenced legal claims against Skaugen to recover all outstanding amounts, damages and losses owed to us. Skaugen has filed a counter-suit against us for amounts unspecified at this time.financing.

During 2017, as an alternative payment for a portion of unpaid amounts Skaugen owed to us, Skaugen offered to us its 35% ownership interest in an LPG carrier, the Norgas Sonoma, which was owned by Skaugen Gulf Petchem Carriers B.S.C.(c), a joint venture between Skaugen (35%), The National Oil & Gas Authority B.S.C.(c) (or Nogaholding) (35%) and Suffun Bahrain W.L.L. (or Suffun) (30%) (or the Skaugen LPG Joint Venture). Both Nogaholding and Suffun exercised their options to participate in the sale of the Norgas Sonoma and as a result, on April 20, 2017, we acquired a 100% ownership interest in the Skaugen LPG Joint Venture for an aggregate purchase price of $13.2 million, including the application of $4.6 million of the outstanding hire owing to us by Skaugen to acquire Skaugen's 35% ownership interest in the Skaugen LPG Joint Venture.
Charter Contracts with Awilco and Loan Refinancings
We have two LNG carriers currently on bareboat charter contracts with Awilco LNG ASA (or Awilco) with original fixed contract terms ending in November 2017 and August 2018 with one-year extension options. Awilco had purchase obligations under the charter contracts to repurchase each vessel from us at the end of their respective terms. As a result of Awilco facing financial challenges, including going concern issues, in June 2017, we amended the charter contracts with Awilco to defer a portion of charter hire and extend the bareboat charter contracts and related purchase obligations on both vessels to December 2019. A key condition of the amendments required Awilco to raise a minimum of $25 million of equity, which was successfully completed in May 2017. The amendments have the effect of deferring between $10,600 per day and $20,600 per day per vessel of charter hire from July 2017 until December 2019, with such deferred amounts added to the purchase obligation amounts.
In July 2017, we completed loan extensions on the facilities secured by the two LNG carriers chartered to Awilco. The loans associated with these vessels, which were previously scheduled to mature between the second quarter of 2018 and the fourth quarter of 2018, have been extended to June 2020 on terms similar to those that existed prior to the extension.
Charter Contracts for MALT LNG Carriers

Two of the six LNG carriers (or MALT LNG Carriers) in theour 52%-owned Teekay LNG-Marubeni Joint Venture, the Marib Spirit and Arwa Spirit, are currently under long-term contracts expiring in 2029charters with Yemen LNG Ltd. (or YLNG), a consortium led by Total SA.YLNG. Due to the political situationunrest in Yemen, YLNG decided to temporarily close operation of its LNG plant in Yemen in 2015. As a result, commencing January 1, 2016, the Teekay LNG-Marubeni Joint Venture agreed in December 2015 to defersuccessive deferral arrangements with YLNG pursuant to which a portion of the charter payments forwere deferred. Concurrent with the anticipated expiry of the most current deferral arrangement, which is expected to occur within the first half of 2019, the Teekay LNG-Marubeni Joint Venture intends to enter into a further agreement with YLNG pursuant to which the Teekay LNG-Marubeni Joint Venture and YLNG will suspend the two LNG carriers from January 1, 2016 to December 31, 2016 and further deferrals were agreed with YLNG to extend the deferral period to the end of the short-term sub-chartercharter contracts for the Marib Spirit and Arwa Spirit, which are currently anticipateda period of up to bein August 2018 and March 2019, respectively, unless the short-term sub-charter contracts are further extended in accordance with their terms.three years. Should the LNG plant in Yemen resumeresumes operations during such suspended term, it is intended that YLNG will be required to repay the applicable deferred amounts in full, plus interest over a period of time to be agreed upon.installments. However, there iswe make no assurance ifwhether or when the LNG plant will resume operations orand, accordingly, if YLNG will be able to repay all or any portion of the deferred amounts, and this deferral period may extend beyond 2018 and 2019 as it relates to the Marib Spirit and Arwa Spirit, respectively.amounts. Our proportionate share of the estimated impact of the charter payment deferral for 20182019 compared to the original charter rates earned prior to

January 1, 2016 is estimated to be a reduction to equity income ranging from $4$7 million to $5$8 million per quarter, (December 31, 2017 - $5.7 million per quarter), which we expect will be partially offset by sub-chartering employment for the Marib Spirit and Arwa Spirit in 2018.2019.

Between July and December 2017,In September 2018, the Teekay LNG-Marubeni Joint Venture securedagreed to charter its LNG carrier, the Magellan Spirit, to us for two years at a fixed rate. In turn, we will charter the Magellan Spirit in the spot market or secure a short-term charter contracts for fourthis vessel. The Magellan Spirit was employed on a charter contract until March 21, 2019 at a charter rate that was significantly higher than the charter-in rate. As of its vessels trading in the short-term market. These short-term charter contracts were secured in respectcompletion of the Magellan SpiritSpirit's (which was deliveredcharter contract in March 21, 2019, we have been in discussions on securing a new charter contract for this vessel.

Commercial Management Agreement for Multi-gas Vessels

On February 25, 2019, we entered into a commercial management agreement (or CMA) with a third-party commercial manager (or the Manager) whereby the Manager agreed to commercially manage and employ our seven multi-gas vessels, with such transition to occur over a period between February 2019 and April 2019. We have the ability to withdraw our vessels from the Manager at any time subject to the chartererrequirements provided in July 2017), the CMA.Marib Spirit (which was delivered to the charterer in October 2017), the Arwa Spirit (which was delivered to the charterer in December 2017) and the Methane Spirit (which was delivered to the charterer in December 2017). It is anticipated that the contractual redeliveries under these various short-term charter contracts will occur during mid-2018 through to early-2019, unless extended in accordance with its terms.

IMPORTANT FINANCIAL AND OPERATIONAL TERMS AND CONCEPTS
We use a variety of financial and operational terms and concepts when analyzing our performance. These include the following:

Voyage Revenues. Voyage revenues currently include revenues from charters accounted for under operating and direct financing leases. Voyage revenues are affected by hire rates and the number of calendar-ship-days a vessel operates. Voyage revenues are also affected by the mix of business between time and voyage charters. Hire rates for voyage charters are more volatile than for time charters, as they are typically tied to prevailing market rates at the time of a voyage.

Voyage Expenses. Voyage expenses are all expenses unique to a particular voyage, including any bunker fuel expenses, port fees, cargo loading and unloading expenses, canal tolls, agency fees and commissions. Voyage expenses are typically paid by the customer under charters and by us under voyage charters.

Net Voyage Revenues. Net voyage revenues represent voyage revenues less voyage expenses. Because the amount of voyage expenses we incur for a particular charter depends upon the type of the charter, we use net voyage revenues to improve the comparability between periods of reported revenues that are generated by the different types of charters. We principally use net voyage revenues, a non-GAAP financial measure, because it provides more meaningful information to us about the deployment of our vessels and their performance than voyage revenues, the most directly comparable financial measure under GAAP.



Vessel Operating Expenses. Under all types of charters and contracts for our vessels, except for bareboat charters, we are responsible for vessel operating expenses, which include crewing, ship management services, repairs and maintenance, insurance, stores, lube oils and communication expenses. The two largest components of our vessel operating expenses are crew costs and repairs and maintenance. We expect these expenses to increase as our fleet matures and to the extent that it expands.

Income from Vessel Operations. To assist us in evaluating our operations by segment, we analyze the income we receive from each segment after deducting operating expenses, but prior to the inclusion or deduction of equity income, interest expense, taxes, foreign currency and derivative gains or losses and other income. For more information, please read “Item 18 – Financial Statements: Note 4 – Segment Reporting.”

Dry docking. We must periodically dry dock each of our vessels for inspection, repairs and maintenance and any modifications required to comply with industry certification or governmental requirements. Generally, we dry dock each of our vessels every two and a half to five years, depending upon the type of vessel and its age. In addition, a shipping society classification intermediate survey is performed on our LNG carriers between the second and third year of a five-year dry-docking period. We capitalize a substantial portion of thecertain costs incurred during dry docking and for the survey, and amortize those costs on a straight-line basis from the completion of a dry docking or intermediate survey overto the estimated useful lifecompletion of the next dry docking. We include in capitalized dry docking those costs incurred as part of the dry dock.docking to meet classification and regulatory requirements. We expense as incurred costs forrelated to routine repairs and maintenance performed during dry docking or intermediate survey that do not improve or extend the useful lives of the assets.docking. The number of dry dockings undertaken in a given period and the nature of the work performed determine the level of dry-docking expenditures.

Depreciation and Amortization. Our depreciation and amortization expense typically consists of the following three components:

charges related to the depreciation of the historical cost of our fleet (less an estimated residual value) over the estimated useful lives of our vessels;
charges related to the amortization of dry-docking expenditures over the useful life of the dry dock; and
charges related to the amortization of the fair value of the time-charters acquired in a 2004 acquisition of four LNG carriers (over the expected remaining terms of the charters).

Revenue Days. Revenue days are the total number of calendar days our vessels were in our possession during a period less the total number of off-hire days during the period associated with major repairs, dry dockings or special or intermediate surveys. Consequently, revenue days represents the total number of days available for the vessel to earn revenue. Idle days, which are days when the vessel is available to earn revenue, yet is not employed, are included in revenue days. We use revenue days to explain changes in our net voyage revenues between periods.

Calendar-Ship-Days. Calendar-ship-days are equal to the total number of calendar days that our vessels were in our possession during a period. As a result, we use calendar-ship-days primarily in explaining changes in vessel operating expenses and depreciation and amortization.

Utilization. Utilization is an indicator of the use of our fleet during a given period and is determined by dividing our revenue days by our calendar-ship-days for the period.
RESULTS OF OPERATIONS
Items You Should Consider When Evaluating Our Results of Operations
Some factors that have affected our historical financial performance and may affect our future performance are listed below:

The amount and timing of dry docking of our vessels can significantly affect our revenues between periods. Our vessels are off-hire at various times due to scheduled and unscheduled maintenance. During 2018, 2017 2016, and 2015,2016, we had 156, 63 none, and 69zero scheduled off-hire days, respectively, relating to the dry docking of our vessels which are consolidated for accounting purposes. In addition, certain of our consolidated vessels had unplanned off-hire of 178 days in 2018, 57 days in 2017, and 39 days in 2016 and 14 days in 2015 relating to repairs. The financial impact from these periods of off-hire, if material, is explained in further detail below.
The size of our fleet changes. Our historical results of operations reflect changes in the size and composition of our fleet due to certain vessel deliveries and sales. Please read “Liquefied Natural Gas Segment”, "Liquefied Petroleum Gas Segment" and “Conventional Tanker Segment” below and “Significant Developments in 20172018 and Early 2018”2019” above for further details about certain prior and future vessel deliveries and sales.
Vessel operating and other costs are facing industry-wide cost pressures. The shipping industry continues to forecast a shortfall in qualified personnel, although weak shipping markets and slowing growth may ease officer shortages. We will continue to focus on our manning and training strategies to meet future needs. In addition, factors such as customer demands for enhanced training and physical equipment, pressure on commodity and raw material prices, as well as changes in regulatory requirements could also contribute to operating expenditure increases. We continue to take action aimed at improving operational efficiencies, and to temper the effect of inflationary and other price escalations; however, increases to operational costs may well occur in the future.
Our financial results are affected by fluctuations in the fair value of our derivative instruments. The change in fair value of our derivative instruments is included in our net income as the majority of our derivative instruments are not designated as hedges for accounting purposes. These changes may fluctuate significantly as interest rates, foreign exchange rates and spot tanker rates fluctuate relating to our interest rate swaps, interest rate swaptions, cross-currencycross currency swaps and to the agreement we havehad with Teekay Corporation


relating to the time charter contract for the Toledo Spirit Suezmax tanker.tanker prior to its sale in 2019. Please read “Item 18 – Financial Statements: Note 11c12d – Related Party Transactions” and “Note 1213 – Derivative Instruments and Hedging Activities.” The unrealized gains or losses relating to changes in fair value of our derivative instruments do not impact our cash flows.
Our financial results are affected by fluctuations in currency exchange rates. Under GAAP, all foreign currency-denominated monetary assets and liabilities (including cash and cash equivalents, restricted cash, accounts receivable, accounts payable, accrued liabilities, advances from affiliates, and long-term debt) are revalued and reported based on the prevailing exchange rate at the end of the period. These foreign currency translations fluctuate based on the strength of the U.S. Dollar relative mainly to the Euro and NOK and are included in our results of operations. The translation of all foreign currency-denominated monetary assets and liabilities at each reporting date results in unrealized foreign currency exchange gains or losses but do not currently impact our cash flows.
TwoCertain of our consolidated conventional tankers, our consolidated LPG carriers and certain of our LNG and LPG carriers in our equity-accounted joint venturesvessels earned revenues based partly on spot market rates. Our previously owned conventional tankers, the European Spirit and African Spirit, our seven wholly-owned LPGmulti-gas carriers, four of our 52%-owned LNG carriers in the Teekay LNG-Marubeni Joint Venture, and certain of our LPG carriers in our 50%-owned Exmar LPG Joint Venture were either trading or are currently trading in the spot market. Volatility of spot rates will affect our results from period to period.

We increased our operating and reporting segments from two to three segments. Prior to 2018, we reported our financial results on the basis of two business segments: a liquified gas segment and a conventional tanker segment. During 2018, our Teekay Multi-Gas Pool commenced operations. As part of this initiative, we completed an internal reorganization and revised our reportable segments, as such changes resulted in management viewing the gas fleet and its components differently. As a result, our LPG and multi-gas carriers are now reported in a separate segment apart from our LNG carriers. Effective as of the fourth quarter of 2018, we manage our business and analyze and report our results from operations on the basis of three business segments: the liquefied natural gas segment, the liquefied petroleum gas segment and the conventional tanker segment. All segment information for comparative periods has been retroactively adjusted to conform with the change in segment presentation adopted in 2018. Details of the changes to our results from operations for the year ended December 31, 2018 compared to the year ended December 31, 2017 for each of our segments are provided below.
Year Ended December 31, 20172018 versus Year Ended December 31, 20162017
Summary

Our consolidated income from vessel operations decreased to $148.6 million for year ended December 31, 2017, compared to $153.2was $147.8 million for the year ended December 31, 2016.2018, compared to $148.6 million for the year ended December 31, 2017. The primary reasons for this decrease, which are reflected in the table below and described following the table, are as follows:

chart-48dc6d1a0461f2ff444.jpg


chart-fadbd42a416b59e3b27.jpg
lower income from vessel operations from our seven multi-gas carriers and two conventional tankers trading in the spot market in 2018 and the Polar Spirit earning a lower time-charter rate upon redeployment;
higher general and administrative expenses in 2018 primarily due to an increase in operational staff relating to new vessel deliveries, higher levels of business development activities and increased professional fees; and
write-downs of goodwill on three conventional vessels and four multi-gas carriers in 2018 and restructuring charges related to the sale of the European Spirit, African Spirit, Teide Spirit and Toledo Spirit conventional tankers in 2017, partially offset by a write-downFebruary 2018, net of the Asian Spirit initial write-downs of four conventional tanker in 2016 and loss on sales of vessels recorded in 2016 upon the charterer, Centrofin Management Inc. (or Centrofin), exercising its purchase options on the Bermuda Spirit and Hamilton Spirit in February 2016 and March 2016, respectively;
a decrease in revenue recognized due to non-payment of charter hire relating to our six LPG carriers on charter to Skaugen in 2017; and
sales of the Bermuda Spirit,Hamilton Spirit and Asian Spirit in April 2016, May 2016 and March 2017, respectively;
partially offset by:
deliveries to us of the Creole Spirit, Oak Spirit and Torben Spirit, Macoma, Murex, Magdala, Myrina, Megara, Bahrain Spiritand MurexSean Spirit LNG carrier newbuildings frombetween February 2016 to November 2017.2017 and December 2018.


We manage our business and analyze and report our results from operations on the basis of two business segments: the liquefied gas segment and the conventional tanker segment. Details of the changes to our results from operations for the year ended December 31, 2017 compared to the year ended December 31, 2016 for each of our segments are provided below.
Liquefied Natural Gas Segment
As at December 31, 2017,2018, our liquefied natural gas segment fleet, including newbuildings, included 5049 LNG carriers and 30 LPG/Multigas carriers, in which our interests ranged from 20% to 100%. However, the table of operating results below only includes the 1823 LNG carriers and seven LPG/Multigas carriers that are accounted for under the consolidation method of accounting.accounting and the Magellan Spirit, a vessel chartered-in from the Teekay LNG-Marubeni Joint Venture and excludes one LNG carrier newbuilding under construction as of December 31, 2018, as well as the vessels and other assets accounted for under the equity method in the following table. The comparison of the results from vessels and assets accounted for under the equity method is described below under Equity Income.

(2)An adjustment has been made during 2018 to reclassify a ship management cost recovery from general and administrative expenses to vessel operating expenses. The 2017 results have also been reclassified to conform to the presentation adopted in 2018.

Our liquefied natural gas segment’s total calendar-ship-days increased by 28.0% to 7,570 days in 2018 from 5,912 days in 2017, as a result of the deliveries of the Torben Spirit, Murex, Macoma, Magdala, Myrina, Megara, Bahrain Spirit and Sean Spirit LNG carrier newbuildings between February 2017 and December 2018 and the Magellan Spirit chartered-in from the Teekay LNG-Marubeni Joint Venture commencing in September 2018. During 2018, vessels in this segment were off-hire for scheduled dry dockings of 30 days, unscheduled off-hire for repairs of 49 days and idle for 66 days for repositioning to other charters, compared to vessels in this segment being off-hire for scheduled dry dockings of 63 days, unscheduled off-hire for repairs of 53 days and idle for three days in the same period of the prior year. As a result, our utilization increased slightly to 98.1% for 2018, compared to 98.0% in 2017.


Net Voyage Revenues. Net voyage revenues increased during 2018 compared to 2017, primarily as a result of:

an increase of $15.0 million due to the delivery of the Magdala and charter contract commencing in February 2018;
an increase of $13.5 million due to the delivery of the Murex andcharter contract commencing in November 2017;
an increase of $12.8 million due to the Magellan Spirit chartered-in from Teekay LNG-Marubeni Joint Venture in September 2018 and commencing its charter-out employment in October 2018;
an increase of $12.6 million due to the delivery of the Macoma andcharter contract commencing in October 2017;
an increase of $11.0 million due to the delivery of the Myrina and charter contract commencing in May 2018;
an increase of $9.7 million due to the delivery of the Torben Spirit andcharter contract commencing in March 2017 and earning an increased charter rate during 2018 upon the charterer extending its original contract in 2017;
an increase of $8.6 million due to the delivery of the Bahrain Spirit in August 2018 and commencement of its charter contract in September 2018;
an increase of $7.8 million due to the delivery of the Megara and charter commencing in July 2018;
an increase of $3.8 million due to the impact of the appreciation of the Euro compared to the U.S. Dollar on our Euro-denominated revenue;
an increase of $2.4 million relating to 35 days of unscheduled off-hire in the second quarter of 2017 due to repairs required for one of our LNG carriers;
an increase of $2.0 million due to the Hispania Spirit being off-hire for 31 days in the first quarter of 2017 for a scheduled dry docking; and
an increase of $1.6 million due to mobilization service fees earned commencing in October 2018 relating to our 30%-owned LNG receiving and regasification terminal under construction in Bahrain (however, we had a corresponding increase in vessel operating expenses);

partially offset by:
a decrease of $5.6 million due to the Polar Spirit earning a lower charter rate upon redeployment after its original charter contract ended during the first quarter of 2018 and 35 days of unscheduled off-hire and idle days during 2018 primarily due to an incident investigation involving a collision with a small vessel and repositioning to other charters;
a decrease of $3.7 million primarily related to additional revenue recognized during the first quarter of 2017 relating to the accelerated dry docking of two LNG carriers in 2017, the costs of which will be recoverable from the charterer;
a decrease of $1.9 million due to the Catalunya Spirit being off-hire for 30 days in 2018 for a scheduled dry docking;
a decrease of $1.7 million relating to amortization of in-process contracts recognized into revenue with respect to our shipbuilding and site supervision contract associated with the four LNG newbuilding carriers in the Pan Union Joint Venture due to the deliveries of the Pan Asia, Pan Americas and Pan Europe LNG carrier newbuildings between October 2017 and July 2018 (however, we had a corresponding decrease in vessel operating expenses); and
a decrease of $1.4 million relating to 20 days of unscheduled off-hire in the fourth quarter of 2018 for the Madrid Spirit due to repairs.
Vessel Operating Expenses. Vessel operating expenses increased during 2018 compared to 2017, primarily as a result of:
an increase of $2.4 million due to deliveries of the Bahrain Spirit, Sean Spirit and Torben Spirit;
an increase of $1.8 million due to the reactivation of the Arctic Spirit from lay-up during the third quarter of 2017; and
an increase of $1.6 million due to mobilization expenses incurred commencing in October 2018 relating to our 30%-owned LNG receiving and regasification terminal under construction in Bahrain (however, we had a corresponding increase in net voyage revenues);
partially offset by:
a decrease of $2.4 million due to higher ship management cost recovery in 2018 as a result of the vessels delivered during the year; and
a decrease of $1.7 million due to lower shipbuilding supervision costs upon the deliveries of Pan Asia, Pan Americas and Pan Europe LNG carrier newbuildings (however, we had a corresponding decrease in net voyage revenues).
Time-charter Hire Expense. Time-charter hire expense increased by $7.7 million as the Magellan Spirit LNG carrier was chartered-in from the Teekay LNG-Marubeni Joint Venture commencing in September 2018.
Depreciation and Amortization. Depreciation and amortization increased by $24.8 million in 2018 compared to 2017 primarily due to the deliveries of the Torben Spirit, Murex, Macoma, Magdala, Myrina, Megara and Sean Spirit.
Equity Income. Equity income increased by $42.6 million in 2018 compared to 2017 as explained below.

The $0.6 million increase in our 33%-owned investment in the four Angola LNG Carriers was primarily due to mark-to-market changes on non-designated derivative instruments. The mark-to-market changes resulted from increases in long-term LIBOR benchmark interest rates for interest rate swaps compared to 2017.

The $1.8 million increase in our 50% investment in the Exmar LNG Carriers was primarily due to a gain of $5.6 million upon the sale of our 50% ownership interest in the Excelsior Joint Venture recorded in equity income, partially offset by lower earnings due to the sale of the Excelsior Joint Venture.

The $15.5 million increase in equity income from our 52% investment in the MALT LNG Carriers was primarily due to higher fleet utilization and higher rates earned as a result of certain vessels that operated in the spot market during 2017 being on short-term charter contracts in 2018.


The $1.6 million decrease in equity income from our 40% investment in the RasGas 3 LNG Carriers was primarily due to higher interest expense due to increase in LIBOR, partially offset by unrealized gains recognized in 2018 relating to its non-designated interest rate swaps compared to unrealized losses in 2017.

The $6.3 million increase in equity income from our investment in the Pan Union LNG Carriers was primarily due to the deliveries of the Pan Union Joint Venture's three LNG carrier newbuildings, the Pan Asia, Pan Americas and Pan Europe, in October 2017, January 2018 and July 2018, respectively, in which we have ownership interests ranging from 20% to 30%.

The $11.4 million increase in equity income from our 50% investment in the Yamal LNG Carriers was primarily due to the deliveries of the Yamal LNG Joint Venture's first two ARC7 LNG carrier newbuildings, the Eduard Toll and Rudolf Samoylovich,in January 2018 and September 2018, respectively, partially offset by ineffectiveness recognized on hedged-accounted interest rate swaps.

The $8.5 million increase in our 30%-owned investment in the Bahrain LNG Joint Venture was primarily due to unrealized gains on designated and non-designated derivative instruments recorded in earnings in 2018 compared to losses recorded in earnings in 2017 due to mark-to-market changes and the sub-charter income earned in 2018 on the Bahrain Spirit.

Liquified Petroleum Gas Segment

As at December 31, 2018, our liquefied petroleum gas segment fleet included 29 LPG and multi-gas carriers, in which our interests ranged from 50% to 99%. However, the table of operating results below only includes the seven multi-gas carriers that are accounted for under the consolidation method of accounting and excludes 22 vessels in the Exmar LPG Joint Venture accounted for under the equity method. The comparison of the results from vessels and assets accounted for under the equity method are described below under Equity Loss.

The following table of operating results compares our liquefied petroleum gas segment’s operating results for 2018 and 2017 and compares its net voyage revenues (which is a non-GAAP financial measure) for 2018 and 2017 to voyage revenues, the most directly comparable GAAP financial measure. The following table of operating results also provides a summary of the changes in calendar-ship-days and revenue days for our liquefied petroleum gas segment:

Our liquefied petroleum gas segment’s total calendar-ship-days increased by 4.5% to 2,555 days in 2018 from 2,445 days in 2017, as a result of the acquisition of the Sonoma Spirit in April 2017. During 2018, vessels in this segment were off-hire for scheduled dry dockings of 97 days, unscheduled off-hire for repairs of 97 days and idle for 112 days for repositioning to other charters, compared to vessels in this segment not being off-hire or idle in the same period of the prior year. As a result, our utilization decreased to 88.0% for 2018, compared to 100.0% in 2017.

Net Voyage Revenues. Net voyage revenues decreased by $10.5 million during 2018 compared to 2017, primarily related to recognition of previous upfront payments received from I.M. Skaugen SE (or Skaugen) during the fourth quarter of 2017 upon termination of charterer contracts with Skaugen.

Vessel Operating Expenses. Vessel operating expenses increased by $17.8 million during 2018 compared to 2017, primarily due to six multi-gas carriers, which were previously on bareboat charter contracts, incurring operating expenses following their redelivery to us from Skaugen during 2017.

Write-down of Goodwill and Vessels. Write-down of vessels of $33.0 million in 2018 were due to the write-downs of the Camilla Spirit, Cathinka Spirit, Napa Spirit and Pan Spirit multi-gas carriers as a result of our evaluation of alternative strategies for these assets, the charter rate environment at the time and the outlook for charter rates for these vessels. In 2018, we conducted our annual goodwill impairment review and concluded that our liquefied petroleum gas segment was impaired and recorded an impairment charge of $0.8 million for the year ended December 31, 2018.
Equity Loss. The $1.2 million improvement in equity loss from our 50% ownership interest in Exmar LPG BVBA (or the Exmar LPG Joint Venture) was primarily due to the impairment losses recorded on the Courcheville and Temse during 2017, partially offset by lower spot rates earned during 2018 compared to 2017 for certain vessels and the sale of the Courcheville in January 2018.

Conventional Tanker Segment
As at December 31, 2018, our conventional tanker fleet included one Suezmax-class double-hulled conventional crude oil tanker, which we lease under capital lease and one Handymax Product tanker, which we own. Two of our conventional tankers, the African Spirit and European Spirit, have been trading in the spot market since the termination of their respective fixed-rate charters in November 2017 and August 2017, respectively. The African Spirit, European Spirit and Toledo Spirit were sold in October 2018, December 2018, and January 2019, respectively. The following table of operating results compares our conventional tanker segment’s operating results for 2018 and 2017, and compares its net voyage revenues (which is a non-GAAP financial measure) for 2018 and 2017 to voyage revenues, the most directly comparable GAAP financial measure. The following table of operating results also provides a summary of the changes in calendar-ship-days and revenue days for our conventional tanker segment:

Our conventional tanker segment's total calendar ship days decreased by 27.0% to 1,389 days in 2018 from 1,904 days in 2017 primarily as a result of the sales of the Asian Spirit, Teide Spirit, European Spirit and African Spirit in March 2017, February 2018, October 2018 and December 2018, respectively. During 2018, the European Spirit was off-hire for 29 days for a scheduled dry docking and 17 days for repairs and the African Spirit and Alexander Spirit had a total of 15 days of unscheduled off-hire due to repairs, compared to 34 idle days for the Asian Spirit after its firm charter contract ended in January 2017 and two unscheduled off-hire days for the African Spirit for repairs during the same period in 2017. As a result, our utilization decreased to 95.6% in 2018 compared to 98.1% in 2017.

Net Voyage Revenues. Net voyage revenues decreased during 2018 compared to 2017, primarily as a result of:

a decrease of $9.5 million due to the sales of the Asian Spirit and Teide Spirit; and
a decrease of $8.4 million as the fixed-rate charter contracts for the European Spirit and African Spirit expired in August and November 2017, respectively, and the vessels earned lower spot rates until they were sold in October and December of 2018, respectively.
Vessel Operating Expenses. Vessel operating expenses decreased during 2018 compared to 2017 by $4.4 million primarily as a result of the sales of the Asian Spirit, Teide Spirit, European Spirit and African Spirit.

Depreciation and Amortization. Depreciation and amortization decreased during 2018 compared to 2017 by $5.3 million primarily as a result of the sales of the Asian Spirit and Teide Spirit, and the reclassification of the European Spirit and African Spirit to vessels held for sale during 2017.

Write-down of vessels. During 2018, we recorded write-downs of $20.9 million. We recorded a write-down of $13.0 million on the Alexander Spirit conventional tanker to its estimated fair value, using an appraised value, as a result of changes in our expectations

of the vessel's future opportunities once its current contract ends in 2019. We also recorded write-downs of $7.9 million on a combined basis on the European Spirit and African Spirit Suezmax tankers as a result of declines in the estimated fair market values of these vessels held for sale. During 2017, we recorded write-downs of $50.6 million. We recorded a write-down of $25.5 million on a combined basis in respect of the Teide Spirit and Toledo Spirit upon the charterer of the Teide Spirit, which is the same charterer of the Toledo Spirit, giving formal notification to us of its intention to terminate its charter contract. In addition, we recorded write-downs of $25.1 million on a combined basis in respect of the European Spirit and African Spirit upon their original contracts ending in 2017 and the vessels being marketed for sale.

Restructuring Charges. The restructuring charges of $1.8 million incurred in 2018 relate to seafarer severance costs upon CEPSA’s sale of the Teide Spirit, our vessel related to capital lease.
Other Operating Results
General and Administrative Expenses. General and administrative expenses increased to $28.5 million for 2018, from $18.1 million for 2017, primarily due to an increase in operational staff relating to new vessel deliveries, higher levels of business development activities, an increase in professional fees primarily due to the lease dispute for our RasGas II LNG Carriers as described above in "Significant Developments in 2018 and Early 2019 – Teekay Nakilat Capital Lease" and due to claims against Skaugen for damages and losses for our multi-gas carriers previously on charter to them.

Interest Expense. Interest expense increased to $128.3 million for 2018, from $80.9 million for 2017. Interest expense primarily reflects interest incurred on our long-term debt and obligations related to capital leases. This increase was primarily the result of:

an increase of $37.1 million primarily due to deliveries of the Torben Spirit, Murex, Macoma, Magdala, Myrina, Megara,Bahrain Spirit and Sean Spirit during 2018 and 2017;
an increase of $7.6 million as a result of higher LIBOR rates, net of principal debt repayments, as compared to the same periods of the prior year; and
an increase of $3.7 million due to decreases in capitalized interest as a result of vessels delivered during 2018 and 2017.

Realized and Unrealized Gain (Loss) on Non-Designated Derivative Instruments. Net realized and unrealized gains (losses) on non-designated derivative instruments increased to $3.3 million for 2018, from $(5.3) million for 2017 as set forth in the table below.

As at December 31, 2018 and 2017, we had interest rate swap agreements, excluding our swap agreements with future commencement dates, with aggregate average net outstanding notional amounts of approximately $919 million and $837 million, respectively, with average fixed rates of 3.3% and 3.5%, respectively. The increases in realized losses relating to our interest rate swaps from 2018 to 2017 were primarily due to an interest rate swap termination in 2018, partially offset by decreases in our settlement payments as a result of the expiration of certain interest rate swaps, which were not renewed, and an increase in LIBOR compared to 2017.

During 2018, we also recognized unrealized gains on our interest rate swap agreements associated with our U.S. Dollar-denominated long-term debt. This resulted from $4.1 million of unrealized gains relating to increases in long-term forward LIBOR benchmark interest rates relative to the beginning of 2018 and reclassification of $8.8 million of previously recognized unrealized losses to realized losses related to actual cash settlements of our interest rate swaps.

During 2018, we recognized unrealized gains on our interest rate swap agreements associated with our Euro-denominated long-term debt. This resulted from reclassification of $19.5 million of previously recognized unrealized losses to realized losses related to actual cash settlements of our interest rate swaps, of which $13.7 million was due to the termination of one of our interest rate swap agreements related to the refinancing of one of our debt facilities, partially offset by $1.3 million of unrealized losses relating to decreases in long-term forward EURIBOR benchmark interest rates relative to the beginning of 2018.

The Toledo Spirit time-charter derivative is the agreement with Teekay Corporation under which Teekay Corporation paid us any amounts payable to the charterer of the Toledo Spirit as a result of spot rates being below the fixed rate, and we paid Teekay Corporation any amounts payable to us by the charterer of the Toledo Spirit as a result of spot rates being in excess of the fixed rate. Please read “Item 18 – Financial Statements: Note 12d – Related Party Transactions." The realized gain of $1.5 million for 2018 relates to lower earnings on our profit-loss-sharing agreement for the Toledo Spirit (we had corresponding decrease in net voyage

revenues). During 2018, we recognized unrealized losses on our Toledo Spirit time-charter derivative contract of $0.9 million. This resulted from a reclassification of previously recognized unrealized gains to realized gains of $1.5 million, partially offset by $0.6 million of unrealized gains relating to decreases in the projected forward tanker rates in the tanker market, relative to the beginning of 2018. The Toledo Spirit was sold in early 2019, and as a result, the derivative agreement ended at that time.

During 2017, we recognized unrealized gains on our interest rate swap and swaption agreements associated with our U.S. Dollar-denominated long-term debt. This resulted from reclassification of $10.9 million of previously recognized unrealized losses to realized losses related to actual cash settlements of our interest rate swaps, partially offset by $2.6 million of unrealized losses relating to decreases in long-term forward LIBOR benchmark interest rates, relative to the beginning of 2017.

During 2017, we also recognized unrealized gains on our interest rate swap agreements associated with our Euro-denominated long-term debt. This resulted from reclassification of $7.9 million of previously recognized unrealized losses to realized losses related to actual cash settlements of our interest rate swaps, partially offset by $2.8 million of unrealized losses relating to decreases in long-term forward EURIBOR benchmark interest rates, relative to the beginning of 2017.

The projected forward average tanker rates in the tanker market decreased slightly at December 31, 2017 compared to the beginning of 2017, which resulted in $0.1 million of unrealized gains on our Toledo Spirit time-charter derivative.

Please see “Item 5 – Operating and Financial Review and Prospects: Critical Accounting Estimates – Valuation of Derivative Instruments,” which explains how our derivative instruments are valued, including the significant factors and uncertainties in determining the estimated fair value and why changes in these factors result in material variances in realized and unrealized gain (loss) on non-designated derivative instruments.

Foreign Currency Exchange Gains (Losses). Foreign currency exchange gains (losses) were $1.4 million and $(26.9) million for 2018 and 2017, respectively. These foreign currency exchange gains (losses) are due primarily to the relevant period-end revaluation of our NOK-denominated debt and our Euro-denominated term loans for financial reporting purposes into U.S. Dollars, net of the realized and unrealized gains and losses on our cross currency swaps. Gains on NOK-denominated and Euro-denominated monetary liabilities reflect a stronger U.S. Dollar against the NOK and Euro on the date of revaluation or settlement compared to the rate in effect at the beginning of the period. Losses on NOK-denominated and Euro-denominated monetary liabilities reflect a weaker U.S. Dollar against the NOK and Euro on the date of revaluation or settlement compared to the rate in effect at the beginning of the period.

For 2018, foreign currency exchange gains (losses) included realized gains of $42.3 million upon maturity of our NOK bonds in 2018, $42.3 million unrealized gains from the transfer of previously recognized unrealized losses to realized losses related to our cross currency swaps associated with the NOK bond which matured in 2018, unrealized gains on the revaluation of our NOK-denominated debt of $19.2 million and unrealized gains on the revaluation of our Euro denominated, non-U.S. Dollar-denominated cash, restricted cash, working capital and debt of $9.8 million. These gains were partially offset by $(42.3) million of realized losses related to the maturity of our cross currency swaps associated with the NOK bonds which matured in 2018, $(42.3) million of unrealized losses from the transfer of previously recognized unrealized gains to realized gains related to the maturity of the NOK bonds in 2018, unrealized losses on our cross currency swaps of ($21.1) million relating to depreciation of long-term NOK forward exchange rates and decreases in long-term forward NIBOR benchmark interest rates relative to the beginning of 2018 and ($6.5) million of realized losses on our cross currency swaps.

For 2017, foreign currency exchange (losses) gains included $(25.7) million of realized losses related to the maturity of our cross currency swaps associated with the NOK bonds which matured in 2017, $(25.7) million of unrealized losses from the transfer of previously recognized unrealized gains to realized gains related to the maturity of the NOK bonds in 2017, realized losses of $(9.3) million on our cross currency swaps, the unrealized losses on the revaluation of our NOK-denominated debt of $(17.6) million, and unrealized losses on the revaluation of our Euro-denominated cash, restricted cash and debt of $(23.3) million. These losses were partially offset by realized gains of $25.7 million upon the maturity of our NOK bonds in 2017, $25.7 million unrealized gains from the transfer of previously recognized unrealized losses to realized losses related to our cross currency swaps associated with the NOK bond which matured in 2017, unrealized gains of $23.3 million on our cross currency swaps primarily due to appreciation of long-term NOK forward exchange rates and increases in long-term forward NIBOR benchmark interest rates relative to the beginning of 2017.

Other Comprehensive (Loss) Income (or OCI). OCI was $(1.1) million in 2018 compared to $4.0 million in 2017, due to changes in the valuation of interest rate swaps accounted for using hedge accounting within the Teekay Nakilat Joint Venture, in which we own a 70% interest, and certain of our equity-accounted joint ventures.
Year Ended December 31, 2017 versus Year Ended December 31, 2016
Liquefied Natural Gas Segment
As at December 31, 2017, our liquefied natural gas segment fleet, including newbuildings, consisted of 50 LNG carriers, in which our interests ranged from 20% to 100%. However, the table of operating results below only includes the 18 LNG carriers that were accounted for under the consolidation method of accounting and excludes six LNG carrier newbuildings under construction as of December 31, 2017 and the following vessels and other assets accounted for under the equity method: (i) the six MALT LNG Carriers in which we have a 52% ownership interest, (ii) four LNG carriers relating to the Angola LNG project (or the Angola LNG Carriers) in which we have a 33% ownership interest, (iii) four LNG carriers relating to our joint venture with QGTC Nakilat (1643-6) Holdings Corporation (or the RasGas 3 LNG Carriers) in which we have a 40% ownership interest, (iv) four LNG carriers, of which three are under construction, in thePan Union Joint Venture in which we have a 30% ownership interest in two LNG carriers and a 20% ownership interestmethod in the other two LNG carriers, (v) six ARC7 LNG carrier newbuildings in which we have a 50% ownership interest through the Yamal LNG Joint Venture, (vi) two LNG carriers in which we have ownership interests ranging from 49% to 50% with Exmar N.V. (or the Exmar LNG Carriers), (vii) 20 LPG carriers and three LPG carrier newbuildings (or the Exmar LPG Carriers) relating to the Exmar LPG Joint Venture, and (viii) the assets for the development of an LNG receiving and regasification terminal in Bahrain in which we have a 30% ownership interest (or the Bahrain LNG Joint Venture).following table.

During 2017, three of our consolidated vessels in this segment werehad 53 unscheduled off-hire days for repairs, two vessels were off-hire for scheduled dry dockings of 63 days, and the Torben Spirit was idle for three days prior to its charter contract commencement, compared to three consolidated vessels in this segment beinghaving 39 unscheduled off-hire days for repairs, and the Creole Spirit and Oak Spirit being idle for 12 days and 15 days, respectively, prior to their charter contract commencements in 2016. As a result, our utilization decreased to 98.6%98.0% for 2017, compared to 99.1%98.7% in 2016.

Net Voyage Revenues. Net voyage revenues increased during 2017 compared to 2016, primarily as a result of:

an increase of $16.6 million due to the Oak Spirit charter contract commencing in August 2016;
an increase of $13.5 million due to the Torben Spirit charter contract commencing in March 2017;
an increase of $10.3 million due to the prepaid lease payments received from Skaugen in prior periods, which were previously deferred and then recognized in 2017 upon the termination of the charter contracts for five of our LPG carriers that were on charter with Skaugen;
an increase of $8.4 million due to the Creole Spirit charter contract commencing in February 2016;
an increase of $6.9 million primarily related to additional revenue recognized relating to the accelerated dry docking of two LNG carriers, the costs of which will be recoverable from the charterer, and higher pass-through operating expenses due to timing of main engine maintenance (however, we had corresponding increases in vessel operating expenses relating to the engine maintenance);


an increase of $3.5 million due to the Macoma charter contract commencing in October 2017;

an increase of $3.0 million relating to amortization of in-process contracts recognized as revenue with respect to our shipbuilding and site supervision contract associated with the four LNG newbuilding carriers in the Pan Union Joint Venture (however, we had corresponding increases in vessel operating expenses); and
an increase of $2.4 million due to the Murex charter contract commencing in November 2017; and
an increase of $1.4 million due to the acquisition of the Sonoma Spirit in April 2017.
partially offset by:

a decrease of $15.1 million due to uncertainty of collection for outstanding hire receivable relating to our six LPG carriers on charter to Skaugen in 2017;
a decrease of $2.4 million relating to 35 days of unscheduled off-hire in the second quarter of 2017 due to repairs required for one of our LNG carriers; and
a net decrease of $0.5 million due to the Hispania Spirit being off-hire for 31 days in the first quarter of 2017 for a scheduled dry docking, partially offset by a reduction in a performance claim recorded in 2016.
Vessel Operating Expenses. Vessel operating expenses increased during 2017 compared to 2016, primarily as a result of:

an increase of $6.0 million due to the deliveries of the Creole Spirit, Oak Spirit and Torben Spirit;
an increase of $3.1 million due to six LPG carriers, which were previously on bareboat charter contracts, incurring operating expenses following their redelivery to us from Skaugen during 2017, and the acquisition of the Sonoma Spirit;
an increase of $3.0 million in relation to our agreement to provide shipbuilding and site supervision costs associated with the four LNG newbuilding carriers in the Pan Union Joint Venture (however, we had corresponding increases in net voyage revenues);
an increase of $3.0 million for two of our LNG carriers as a result of the timing of main engine maintenance (however, we had corresponding increases in net voyage revenues); and
an increase of $2.0 million for certain of our LNG carriers due to the timing of repairs and maintenance.
Depreciation and Amortization. Depreciation and amortization increased by $14.9$14.4 million in 2017 compared to 2016 primarily due to the deliveries of the Creole Spirit,Oak Spirit, Torben Spirit, Macoma, and Murex, and higher dry-dock amortization due to recent dry dockings of our LNG carriers.

The $1.0 million increase in our 33% investment in the four Angola LNG Carriers was primarily due to an increase in unrealized gains on non-designated derivative instruments due to mark-to-market changes. The mark-to-market changes resulted from changes in long-term LIBOR benchmark interest rates for interest rate swaps compared to 2016.

The $1.6 million decrease in our 50% investment in the Exmar LNG Carriers was primarily due to the Excalibur being off-hire in 2017 for a scheduled dry docking.

The $21.1 million decrease in equity income from our 52% investment in the MALT LNG Carriers was primarily due to a settlement payment awarded to the joint venture in 2016 for the disputed contract termination relating to the Magellan Spirit, of which our proportionate share was $20.3 million; and a further deferral effective August 2016 of a portion of the charter payments for the Marib Spirit and Arwa Spirit that are chartered to service the YLNG plant in Yemen, which has been closed since 2015. These decreases were partially offset by higher fleet utilization in the second half of 2017 due to commencements of short-term charter contracts for certain vessels which were previously trading in the spot market.

The $3.5 million decrease in equity income from our 40% investment in the RasGas 3 LNG Carriers was primarily due to higher interest expense resulting from the completion of debt refinancing in December 2016.

The $0.6 million increase in equity income from our investment in the Pan Union LNG Carriers was primarily due to the delivery of the Pan Union Joint Venture's first LNG carrier newbuilding, the Pan Asia, in October 2017.

The $6.4 million decrease in our other equity-accounted investments was primarily due to unrealized losses on interest rate swaps relating to our 30% ownership interest in the Bahrain LNG Joint Venture in 2017, and higher crew training expenses for the Yamal LNG Joint Venture in preparation for its vessel deliveries which commenced in 2018.

Liquefied Petroleum Gas Segment

As at December 31, 2017, our liquefied petroleum gas segment fleet, including newbuildings, consisted of 30 LPG/multi-gas carriers, in which our interests ranged from 50% to 99%. However, the table of operating results below only includes the seven multi-gas carriers that are accounted for under the consolidation method of accounting and excludes 20 delivered vessels and three newbuildings in the Exmar

LPG Joint Venture accounted for under the equity method. The comparison of the results from vessels and assets accounted for under the equity method are described below under Equity (Loss) Income.

The following table of operating results compares our liquefied petroleum gas segment’s operating results for 2017 and 2016 and compares its net voyage revenues (which is a non-GAAP financial measure) for 2017 and 2016, to voyage revenues, the most directly comparable GAAP financial measure. The following table of operating results also provides a summary of the changes in calendar-ship-days and revenue days for our liquefied petroleum gas segment:

Our liquefied petroleum gas segment’s total calendar-ship-days increased by 11.3% to days 2,445 days in 2017 from days 2,196 days in 2016 as a result of our acquisition of the Sonoma Spirit in 2017.

Net Voyage Revenues. Net voyage revenues decreased during 2017 compared to 2016, primarily as a result of:

a decrease of $15.1 million due to uncertainty of collection for outstanding hire receivable relating to our six LPG carriers on charter to Skaugen in 2017;
partially offset by:

an increase of $10.3 million due to the prepaid lease payments received from Skaugen in prior periods, which were previously deferred and then recognized in 2017 upon the termination of the charter contracts for five of our LPG carriers that were on charter with Skaugen; and
an increase of $1.4 million due to the acquisition of the Sonoma Spirit in April 2017.
Vessel Operating Expenses. Vessel operating expenses increased during 2017 compared to 2016 by $3.1 million primarily due to six LPG carriers, which were previously on bareboat charter contracts, incurring operating expenses following their redelivery to us from Skaugen during 2017, and the acquisition of the Sonoma Spirit.

Equity (Loss) Income. The $21.5 million decrease in equity income from our 50% ownership interest in the Exmar LPG Joint Venture was primarily due to more vessels trading in the spot market at lower rates during 2017 compared to higher fixed rates earned in 2016. Other factors that caused the decrease included the scheduled dry dockings of the Eupen and Brussels in the second and third quarters of 2017, respectively, vessel write-downs of the Courcheville and Temse recorded in 2017, and the sale of the Brugge Venture in January 2017. These decreases were partially offset by revenues earned from five LPG carrier newbuildings that delivered to the Exmar LPG Joint Venture between February 2016 and July 2017, and a write-down of the Brugge Venture recorded in 2016.

Conventional Tanker Segment
As at December 31, 2017, our conventional tanker fleet included four Suezmax-class double-hulled conventional crude oil tankers and one Handymax Product tanker, three of which we own (including the European Spiritand African Spirit which arewere classifiedas held for sale) and two of which we lease under capital leases. Three of our five conventional tankers operate under fixed-rate charters;charters, the European Spirit and African Spirithave been were trading in the spot market in August and November 2017, respectively, as we continuecontinued to market thesethose vessels for sale.

The following table of operating results compares our conventional tanker segment’s operating results for 2017 and 2016 and compares its net voyage revenues (which is a non-GAAP financial measure) for 2017 and 2016 to voyage revenues, the most directly comparable GAAP financial measure.

(2)An adjustment was made during 2018 to reclassify a ship management cost allocation recovery from general and administrative expenses to vessel operating expenses. The 2017 and 2016 results have also been reclassified to conform to the presentation adopted in 2018.

Our conventional tanker segment's total calendar ship days decreased by 21.9% to 1,904 days in 2017 from 2,439 days in 2016 primarily as a result of the sales of the Bermuda Spirit, Hamilton Spiritand Asian Spiritin April 2016, May 2016 and March 2017, respectively.During 2017, the Asian Spiritwas idle for 34 days between the time its firm charter contract ended in January 2017 and the time the vessel was sold and the European Spiritwas off-hire for two days for vessel maintenance, compared to no off-hire days during 2016. As a result, our utilization decreased to 98.1% in 2017 compared to 100.0% in 2016.2016

Net Voyage Revenues. Net voyage revenues decreased during 2017 compared to 2016, primarily as a result of:

a decrease of $14.0 million primarily due to the sales of the Bermuda Spirit, Hamilton Spirit, and Asian Spirit;
a decrease of $2.1 million as the fixed-rate charter contracts for the European Spirit and African Spirit expired in August and November 2017, respectively, and the vessels earned lower spot rates during the periods after their respective contracts expired; and
a decrease of $1.3 million due to lower revenues earned by the Toledo Spirit in 2017 relating to the profit-sharing agreement between us and CEPSA (however, we had a corresponding decrease in our realized loss on our associated derivative contract with Teekay Corporation; therefore, this decrease and future increases or decreases related to this agreement did not and will not affect our cash flow or net income).

Vessel Operating Expenses. Vessel operating expenses decreased during 2017 compared to 2016 primarily as a result of the sales of the Bermuda Spirit, Hamilton Spirit and Asian Spirit.

Depreciation and Amortization. Depreciation and amortization decreased during 2017 compared to 2016 primarily as a result of the sales of the Bermuda Spirit, Hamilton Spirit and Asian Spirit, the reclassification of the European Spirit to held for sale in the second quarter of 2017, and the vessel write-down of the African Spirit recorded in the third quarter of 2017.

Write-down and loss on sale of vessels. During 2017, we recorded write-downs of $50.6 million. During the second quarter of 2017, we recorded a write-down of the European Spirit of $12.6 million to its estimated fair value as we commenced marketing the vessel for sale upon the charterer notifying us it was redelivering the vessel to us upon completion of its charter contract in August 2017. During the third quarter of 2017, we recorded a write-down of the African Spirit of $12.5 million to its estimated fair value as we received notification from the charterer in August 2017 that it would redeliver the vessel to us upon completion of its charter contract in November 2017. In August 2017, the charterer of the Teide Spirit gave formal notification to us of its intention to terminate its charter contract subject to certain conditions being met and third-party approvals being received. In February 2018,Based on our prior experience with the charterer, soldwe expected in 2017 that the Teide Spirit and concurrently terminated its existingcharterer would cancel the charter contract with us. The charterer’s cancellation option for the Toledo Spirit is first exercisable in August 2018. Given our prior experience with this charterer, we expect it will also cancel the charter contract and sell the Toledo Spirit to a third party in 2018.. We recorded a $25.5 million write-down on a combined basis in respect of the Teide Spirit and Toledo Spirit in 2017. During 2016, we incurred losses on the sales of the Bermuda Spirit and Hamilton Spirit of $27.4 million, and recorded a write-down of $11.5 million to its estimated fair value for the Asian Spirit upon completion of its charter contract and marketing the vessel for sale.
Other Operating Results
General and Administrative Expenses. General and administrative expenses decreased to $16.5$18.1 million for 2017, from $18.5$19.2 million for 2016, primarily due to lower levels of business development activities in 2017 compared to 2016, which was partially offset by reimbursement from the Bahrain LNG Joint Venture in 2016 of our proportionate share of certain costs we paid, including pre-operation, engineering and financing-related expenses, upon the joint venture securing debt financing in the fourth quarter of 2016.

Equity Income. Equity income decreased to $9.8 million for 2017, from $62.3 million for 2016, as set forth in the table below:

The $1.0 million increase in our 33% investment in the four Angola LNG Carriers was primarily due to an increase in unrealized gains on non-designated derivative instruments due to mark-to-market changes. The mark-to-market changes resulted from changes in long-term LIBOR benchmark interest rates for interest rate swaps compared to 2016.

The $1.6 million decrease in our 50% investment in the two Exmar LNG Carriers was primarily due to the Excalibur being off-hire in 2017 for a scheduled dry docking.

The $21.5 million decrease in equity income from our 50% ownership interest in Exmar LPG BVBA was primarily due to more vessels trading in the spot market at lower rates during 2017 compared to higher fixed rates earned in 2016. Other factors that caused the decrease include the scheduled dry dockings of the Eupen and Brussels in the second and third quarters of 2017, respectively, vessel write-downs of the Courcheville and Temse recorded in 2017, and the sale of the Brugge Venture in January 2017. These decreases were partially


offset by revenues earned from five LPG carrier newbuildings that delivered to the Exmar LPG Joint Venture between February 2016 and July 2017, and a write-down of the Brugge Venture recorded in 2016.

The $21.1 million decrease in equity income from our 52% investment in the MALT LNG Carriers was primarily due to a settlement payment awarded to the joint venture in 2016 for the disputed contract termination relating to the Magellan Spirit, of which our proportionate share was $20.3 million; and a further deferral effective August 2016 of a portion of the charter payments for the Marib Spirit and Arwa Spirit that are chartered to service the YLNG plant in Yemen, which has been closed since 2015. These decreases were partially offset by higher fleet utilization in the second half of 2017 due to commencements of short-term charter contracts for certain vessels which were previously trading in the spot market.

The $3.5 million decrease in equity income from our 40% investment in the RasGas 3 LNG Carriers was primarily due to higher interest expense resulting from the completion of debt refinancing in December 2016.

The $0.6 million increase in equity income from our investment in the Pan Union Joint Venture was primarily due to the delivery of its first LNG carrier newbuilding, the Pan Asia, in October 2017.

The $6.4 million decrease in our other equity-accounted investments was primarily due to unrealized losses on interest rate swaps relating to our 30% ownership interest in the Bahrain LNG Joint Venture in 2017, and higher crew training expenses for the Yamal LNG Joint Venture in preparation for its vessel deliveries commencing in 2018.

Interest Expense. Interest expense increased to $80.9 million for 2017, from $58.8 million for 2016. Interest expense primarily reflects interest incurred on our long-term debt and obligations related to capital leases. This increase was primarily the result of:

an increase of $16.3 million primarily relating to interest incurred on the obligations related to capital leases for the Creole Spirit, Oak Spirit, Torben Spirit, Murex, and Macoma commencing upon their deliveries in 2016 and 2017;
an increase of $4.6 million as a result of our issuances of NOK bonds in October 2016 and January 2017, net of our NOK bond repurchases in October 2016 and the maturity of certain of the NOK bonds in May 2017; and
an increase of $4.1 million as a result of interest expense accretion on the Pan Union Joint Venture crew training and site supervision obligation, and higher LIBOR rates net of debt principal repayments;
partially offset by:
a decrease of $4.1 million due to increases in capitalized interest relating to additional advances and capital contributions to the Yamal LNG Joint Venture and Bahrain LNG Joint Venture for newbuilding installments and construction costs.

Realized and Unrealized Loss on Non-Designated Derivative Instruments. Net realized and unrealized losses on non-designated derivative instruments decreased to $5.3 million for 2017, from $7.2 million for 2016 as set forth in the table below.

As at December 31, 2017 and 2016, we had interest rate swap agreements, excluding our swap agreements with future commencement
dates, with aggregate average net outstanding notional amounts of approximately $837 million and $755 million, respectively, with average
fixed rates of 3.5% and 3.8%, respectively. The decreases in realized losses relating to our interest rate swaps from 2016 to 2017 was primarily due to an increase in LIBOR compared to lastthe prior year, which decreased our settlement payments, and the expiration of certain interest rate swaps, which were not renewed.

During 2017, we recognized unrealized gains on our interest rate swap and swaption agreements associated with our U.S. Dollar-denominated long-term debt. This resulted from reclassification of $10.9 million of previously recognized unrealized losses to realized losses related to actual cash settlements of our interest rate swaps, partially offset by $2.6 million of unrealized losses relating to decreases in long-term forward LIBOR benchmark interest rates, relative to the beginning of 2017.

During 2017, we also recognized unrealized gains on our interest rate swap agreements associated with our Euro-denominated long-term debt. This resulted from reclassification of $7.9 million of previously recognized unrealized losses to realized losses related to actual cash settlements of our interest rate swaps, partially offset by $2.8 million of unrealized losses relating to decreases in long-term forward EURIBOR benchmark interest rates, relative to the beginning of 2017.



The projected forward average tanker rates in the tanker market decreased slightly at December 31, 2017 compared to the beginning of 2017, which resulted in $0.1 million of unrealized gains on our Toledo Spirit time-charter derivative. The Toledo Spirit time-charter derivative is the agreement with Teekay Corporation under which Teekay Corporation payspaid us any amounts payable to the charterer of the Toledo Spirit as a result of spot rates being below the fixed rate, and we paypaid Teekay Corporation any amounts payable to us by the charterer of the Toledo Spirit as a result of spot rates being in excess of the fixed rate. The Toledo Spirit was sold in early 2019 and as a result, the derivative agreement ended at that time.

During 2016, we recognized unrealized gains on our interest rate swap and swaption agreements associated with our U.S. Dollar-denominated long-term debt. This resulted from transfers of $17.9 million of previously recognized unrealized losses to realized losses related to actual cash settlements of our interest rate swaps, partially offset by $3.7 million of unrealized losses relating to decreases in long-term forward LIBOR benchmark interest rates relative to the beginning of 2016.

During 2016, we also recognized unrealized gains on our interest rate swap agreements associated with our EURO-denominatedEuro-denominated long-term debt. This resulted from transfers of $8.1 million of previously recognized unrealized losses to realized losses related to actual cash settlements of our interest rate swaps, partially offset by $6.7 million of unrealized losses relating to decreases in long-term forward EURIBOR benchmark interest rates, relative to the beginning of 2016.

The projected forward average tanker rates in the tanker market decreased at December 31, 2016 compared to the beginning of 2016, which resulted in $4.0 million of unrealized gains on our Toledo Spirit time-charter derivative.


Please see “Item 5 – Operating and Financial Review and Prospects: Critical Accounting Estimates – Valuation of Derivative Instruments,” which explains how our derivative instruments are valued, including the significant factors and uncertainties in determining the estimated fair value and why changes in these factors result in material variances in realized and unrealized gain (loss) on non-designated derivative instruments.

Foreign Currency Exchange Gains. Foreign currency exchange (losses) gains were $(26.9) million and $5.3 million for 2017 and 2016, respectively. These foreign currency exchange (losses) gains arewere due primarily to the relevant period-end revaluation of our NOK-denominated debt and our Euro-denominated term loans for financial reporting purposes into U.S. Dollars, net of the realized and unrealized gains and losses on our cross-currencycross currency swaps. Gains on NOK-denominated and Euro-denominated monetary liabilities reflect a stronger U.S. Dollar against the NOK and Euro on the date of revaluation or settlement compared to the rate in effect at the beginning of the period. Losses on NOK-denominated and Euro-denominated monetary liabilities reflect a weaker U.S. Dollar against the NOK and Euro on the date of revaluation or settlement compared to the rate in effect at the beginning of the period.

For 2017, foreign currency exchange (losses) gains included $(25.7) million of realized losses related to the maturity of our cross-currencycross currency swaps associated with the NOK bonds which matured in 2017, $(25.7) million of unrealized losses from the transfer of previously recognized unrealized gains to realized gains related to the maturity of the NOK bonds in 2017, realized losses of $(9.3) million on our cross-currencycross currency swaps, the unrealized losses on the revaluation of our NOK-denominated debt of $(17.6) million, and unrealized losses on the revaluation of our Euro-denominated cash, restricted cash and debt of $(23.3) million. These losses were partially offset by realized gains of $25.7 million upon the maturity of our NOK bonds in 2017, $25.7 million unrealized gains from the transfer of previously recognized unrealized losses to realized losses related to our cross-currencycross currency swaps associated with the NOK bond which matured in 2017, unrealized gains of $23.3 million on our cross-currencycross currency swaps primarily due to appreciation of long-term NOK forward exchange rates and increases in long-term forward NIBOR benchmark interest rates relative to the beginning of 2017.

For 2016, foreign currency exchange gains (losses) included realized gains of $16.8 million on the repurchase of a portion of our NOK bonds maturing in 2017, the transfer of $17.7 million of previously recognized unrealized losses to realized losses related to our cross-currencycross currency swaps associated with the NOK bond repurchase, unrealized gains of $11.2 million on our cross-currencycross currency swaps primarily due to appreciation of long-term NOK forward exchange rates and increases in long-term forward NIBOR benchmark interest rates relative to the beginning of 2016, and $5.4 million on the revaluation of our Euro-denominated cash, restricted cash and debt. These gains were partially offset by transfers of $(16.8) million of previously recognized unrealized gains to realized gains related to the repurchase of the NOK bonds in October 2016, $(17.7) million of realized losses related to the termination of our cross-currencycross currency swaps associated with the NOK bond repurchase, $(9.1) million realized losses on settlements of our cross-currencycross currency swaps and a $(2.2) million loss on the revaluation of our NOK-denominated debt.

Other Comprehensive Income (Loss) (or OCI). OCI was $4.0 million in 2017 compared to $2.8 million in 2016, due to changes in the valuation of interest rate swaps accounted for using hedge accounting within the Teekay Nakilat Joint Venture, in which we own a 70% interest, and certain of our equity-accounted joint ventures.

Liquefied Gas Segment
As at December 31, 2016, our liquefied gas segment fleet, including newbuildings, consisted of 50 LNG carriers and 29 LPG/Multigas carriers, in which our interests ranged from 20% to 100%. However, the table below only includes the 15 LNG carriers and six LPG/Multigas carriers that are accounted for under the consolidation method of accounting, 19 of which we own and two of which we lease under capital leases. The table excludes nine LNG carrier newbuildings under construction as at December 31, 2016 and the following vessels accounted for under the equity method: (i) the six MALT LNG Carriers in which we have a 52% ownership interest, (ii) four Angola LNG Carriers in which we have a 33% ownership interest, (iii) four RasGas 3 LNG Carriers in which we have a 40% ownership interest, (iv) four LNG carrier newbuildings in the Pan Union Joint Venture in which we have a 30% ownership interest in two LNG carrier newbuildings and a 20% ownership interest in the other two LNG carrier newbuildings, (v) six LNG carrier newbuildings relating to the Yamal LNG Joint Venture in which we have a 50% ownership interest, (vi) two Exmar LNG carriers in which we have ownership interests ranging from 49%


to 50%, (vii) 19 Exmar LPG carriers and four Exmar LPG carrier newbuildings relating to our 50/50 joint venture with Exmar, and (viii) the assets for the development of an LNG receiving and regasification terminal related to the Bahrain LNG Joint Venturein which we have a 30% ownership interest. The comparison of the results from vessels accounted for under the equity method are described below under Other Operating Results – Equity Income.

The following table compares our liquefied gas segment’s operating results for 2016 and 2015, and compares its net voyage revenues (which is a non-GAAP financial measure) for 2016 and 2015, to voyage revenues, the most directly comparable GAAP financial measure. The following table also provides a summary of the changes in calendar-ship-days and revenue days for our liquefied gas segment:

Our liquefied gas segment’s total calendar-ship-days increased by 7.3% to 7,440 days in 2016 from 6,935 days in 2015, as a result of the deliveries to us of the Creole Spirit and Oak Spirit on February 18, 2016 and July 19, 2016, respectively. During 2016, one of our consolidated vessels in this segment was off-hire for a scheduled in-water survey, the Creole Spirit was off-hire for 32 days for repairs covered under warranty, and the Creole Spirit and Oak Spirit's time-charter contracts commenced in February and August 2016, respectively, compared to one consolidated vessel in this segment being off-hire for 47 days in 2015. As a result, our utilization decreased to 99.1% for 2016, compared to 99.3% in 2015.

Net Voyage Revenues. Net voyage revenues increased during 2016 compared to 2015, primarily as a result of:

an increase of $22.4 million as a result of the Creole Spirit charter contract commencing in February 2016;
an increase of $12.7 million as a result of the Oak Spirit charter contract commencing in August 2016;
an increase of $2.2 million due to the Polar Spirit being off-hire for 47 days in 2015 for a scheduled dry docking; and
an increase of $2.1 million relating to amortization of in-process contracts recognized as revenue with respect to our shipbuilding and site supervision contract associated with the four LNG newbuilding carriers in the Pan Union Joint Venture (however, we had a corresponding increase in vessel operating expenses);

partially offset by:

a decrease of $4.5 million due to uncertainty of collection for outstanding hire receivable relating to our six LPG carriers on charter to Skaugen in the fourth quarter of 2016; and
a decrease of $2.0 million for our Spanish LNG carriers primarily due to a performance claim related to the Hispania Spirit recorded in the fourth quarter of 2016 and the Catalunya Spirit being off-hire for six days in the first quarter of 2016 for a scheduled in-water survey.

Vessel Operating Expenses. Vessel operating expenses increased during 2016 compared to 2015, primarily as a result of:

an increase of $3.9 million due to the delivery of the Creole Spirit;
an increase of $2.5 million due to the delivery of the Oak Spirit; and
an increase of $2.1 million in relation to our agreement to provide shipbuilding and site supervision costs associated with the four LNG newbuilding carriers in the Pan Union Joint Venture (however, we had a corresponding increase in net voyage revenues);

partially offset by:



a decrease of $3.8 million due to the charterer, Teekay Corporation, not being able to find employment for the Arctic Spirit and Polar Spirit for a significant portion of 2016, which permitted us to operate the vessels with a reduced average number of crew on board and reduce the amount of repair and maintenance activities performed; and
a decrease of $1.3 million relating to crew training costs for our LNG carrier newbuildings as a result of the deliveries of the Creole Spirit and Oak Spirit.
Depreciation and Amortization. Depreciation and amortization increased by $8.8 million in 2016 compared to 2015 primarily due to the deliveries of the Creole Spirit and Oak Spirit.

Conventional Tanker Segment
As at December 31, 2016, our fleet included five Suezmax-class double-hulled conventional crude oil tankers and one Handymax product tanker, three of which we own, two of which we lease under capital leases, and one vessel held for sale.

The following table compares our conventional tanker segment’s operating results for 2016 and 2015, and compares its net voyage revenues (which is a non-GAAP financial measure) for 2016 and 2015 to voyage revenues, the most directly comparable GAAP financial measure. The following table also provides a summary of the changes in calendar-ship-days and revenue days for our conventional tanker segment:

(1)Includes direct general and administrative expenses and indirect general and administrative expenses (allocated to each segment based on estimated use of corporate resources).

Our conventional tanker segment's total calendar ship days decreased by 16.5% to 2,439 days in 2016 from 2,920 days in 2015 primarily as a result of the sales of the Bermuda Spirit and Hamilton Spirit in April 2016 and May 2016, respectively. During 2016, none of our vessels in this segment were off-hire for scheduled dry dockings, compared to two of our vessels in this segment being off-hire for a total of 24 days for scheduled dry dockings and another vessel being off-hire for 12 days relating to a crew work stoppage during 2015. As a result, our utilization increased to 100.0% in 2016 compared to 98.8% in 2015.

Net Voyage Revenues. Net voyage revenues decreased during 2016 compared to 2015, primarily as a result of:

a decrease of $14.2 million due to the sales of the Bermuda Spirit and Hamilton Spirit in April 2016 and May 2016, respectively;
a decrease of $4.4 million due to lower revenues earned by the Teide Spirit relating to the profit-sharing agreement between us and CEPSA;
a decrease of $4.2 million in pass-through vessel operating expenses due to the change in crew nationality on board the Alexander Spirit in September 2015 (however, we had a corresponding decrease in vessel operating expenses);
a decrease of $4.0 million due to our recovery during 2015 of crew restructuring charges in that amount from the charterer of the Alexander Spirit, who had requested we change the crew nationality on board the vessel (however, because we had a corresponding increase in our restructuring charges, this increase in revenue did not affect our cash flow or net income);
a decrease of $3.6 million relating to the European Spirit, African Spirit and Asian Spirit upon the charterer exercising its one-year extension options in September 2015, November 2015 and January 2016, respectively, at lower charter rates than the original charter rates; and
a decrease of $2.8 million due to lower revenues earned by the Toledo Spirit in 2016 relating to the profit-sharing agreement between us and CEPSA (however, we had a corresponding decrease in our realized loss on our associated derivative contract with Teekay Corporation; therefore, this decrease and future increases or decreases related to this agreement did not and will not affect our cash flow or net income).



Vessel Operating Expenses. Vessel operating expenses decreased during 2016 compared to 2015 primarily as a result of:

a decrease of $4.2 million in crew wages due to the change in crew nationality on board the Alexander Spirit in September 2015 (however, we had a corresponding decrease in net voyage revenues); and
a decrease of $3.6 million due to the sales of the Bermuda Spirit and Hamilton Spirit.

Depreciation and Amortization. Depreciation and amortization decreased by $5.5 million during 2016 compared to 2015, primarily as a result of Centrofin exercising its purchase options on the Bermuda Spirit and Hamilton Spirit in February 2016 and March 2016, respectively, and our subsequent sales of these vessels.

Write-down and loss on sale of vessels. During 2016, we incurred a loss on sale of vessels of $27.4 million upon Centrofin exercising its purchase options on the Bermuda Spirit and Hamilton Spirit. In addition, we incurred a loss of $11.5 million when we agreed to sell the Asian Spirit in November 2016. This vessel was classified as held for sale at December 31, 2016.

Restructuring Charges. The restructuring charges of $4.0 million for 2015 related to seafarer severance payments made as a result of the request by the charterer to change the crew nationality on board the Alexander Spirit (however, we had a corresponding increase in our net voyage revenues as the charterer is responsible for all the severance payments; therefore, this increase in restructuring expense did not affect our cash flow or net income).
Other Operating Results
General and Administrative Expenses. General and administrative expenses decreased to $18.5 million for 2016, from $25.1 million for 2015, primarily due to reimbursement from the Bahrain Joint Venture in 2016 of our proportionate share of certain costs we paid, including pre-operation, engineering and financing-related expenses, upon the joint venture securing debt financing in the fourth quarter of 2016. A reduced amount of business development activities in 2016 also contributed to the decrease in general and administrative expenses.

Equity Income. Equity income decreased to $62.3 million for 2016, from $84.2 million for 2015, as set forth in the table below:

Difference(431)(294)(19,059)(117)(1,710)(253)(21,864)

The $0.4 million decrease in our 33% investment in the four Angola LNG Carriers was primarily due to decreases in voyage revenues due to the positive impact of charter contract amendments in the second quarter of 2015 to allow for dry docking and operating costs to be passed-through to the charterer, retroactive to the beginning of the charter contract, which was partially offset by scheduled dry dockings for all four vessels in the joint venture in 2015 and higher unrealized gains on non-designated derivative instruments in 2016 as a result of a higher increase in long-term LIBOR benchmark interest rates compared to last year.

Equity income from our 50% ownership interest in Exmar LPG BVBA decreased by $19.1 million primarily due to: more vessels trading in the spot market in 2016 compared to higher fixed rates earned in 2015; the redelivery of the in-chartered vessel Odin back to its owner in November 2015; and the write-down of the Brugge Venture recorded in the fourth quarter of 2016, which was sold in January 2017. These decreases were partially offset by the deliveries to the joint venture of four LPG carrier newbuildings between September 2015 and November 2016.

The slight decrease in equity income from our 52% investment in the MALT LNG Carriers was primarily due to the deferral during 2016 of a significant portion of the charter payments for the Marib Spirit and Arwa Spirit LNG carriers chartered to support the LNG plant in Yemen, and a lower charter rate on the redeployment of the Methane Spirit after its original time-charter contract expired in March 2015. These decreases were partially offset by the settlement payment awarded to us in 2016 for the disputed contract termination relating to the Magellan Spirit, and unscheduled off-hire relating to the Woodside Donaldson to repair a damaged propulsion motor in January 2015.

The $1.7 million decrease in equity income from our 40% investment in the RasGas 3 LNG Carriers was primarily due to the scheduled maturity of the joint venture's interest rate swaps, which resulted in lower unrealized gain on non-designated derivative instruments, which was partially offset by lower combined interest expense and realized loss on non-designated derivative instruments.

Interest Expense. Interest expense increased to $58.8 million for 2016, from $43.3 million for 2015. Interest expense primarily reflects interest incurred on our long-term debt and obligations related to capital leases. This increase was primarily the result of:

an increase of $8.0 million relating to interest incurred on the obligation related to capital lease for the Creole Spirit commencing upon its delivery in February 2016;


an increase of $4.1 million relating to interest incurred on the obligation related to capital lease for the Oak Spirit commencing upon its delivery in July 2016; and
a net increase of $3.3 million due to the combined effect of an increase in LIBOR on our floating-rate debt, and lower principal balances due to debt repayments during 2016 and 2015.

Realized and Unrealized Loss on Non-Designated Derivative Instruments. Net realized and unrealized losses on non-designated derivative instruments decreased to $7.2 million for 2016, from $20.0 million for 2015 as set forth in the table below.

As at December 31, 2016 and 2015, we had interest rate swap agreements, excluding our swap agreements with future commencement
dates, with aggregate average net outstanding notional amounts of approximately $755 million and $819 million, respectively, with average
fixed rates of 3.8% for both years. The decreases in realized losses relating to our interest rate swaps from 2015 to 2016 was primarily due to an increase in LIBOR compared to last year, which decreased our settlement payments.

During 2016, we recognized unrealized gains on our interest rate swap and swaption agreements associated with our U.S. Dollar-denominated long-term debt. This resulted from transfers of $17.9 million of previously recognized unrealized losses to realized losses related to actual cash settlements of our interest rate swaps, partially offset by $3.7 million of unrealized losses relating to decreases in long-term forward LIBOR benchmark interest rates relative to the beginning of 2016.

During 2016, we recognized unrealized gains on our interest rate swap agreements associated with our EURO-denominated long-term debt. This resulted from transfers of $8.1 million of previously recognized unrealized losses to realized losses related to actual cash settlements of our interest rate swaps, partially offset by $6.7 million of unrealized losses relating to decreases in long-term forward EURIBOR benchmark interest rates, relative to the beginning of 2016.

The projected forward average tanker rates in the tanker market decreased at December 31, 2016 compared to the beginning of 2016, which resulted in $4.0 million of unrealized gains on our Toledo Spirit time-charter derivative. The Toledo Spirit time-charter derivative is the agreement with Teekay Corporation under which Teekay Corporation pays us any amounts payable to the charterer of the Toledo Spirit as a result of spot rates being below the fixed rate, and we pay Teekay Corporation any amounts payable to us by the charterer of the Toledo Spirit as a result of spot rates being in excess of the fixed rate.

During 2015, we recognized unrealized gains on our interest rate swap and swaption agreements associated with our U.S. Dollar-denominated long-term debt. This resulted from transfers of $21.0 million of previously recognized unrealized losses to realized losses related to actual cash settlements of our interest rate swaps, partially offset by $17.1 million of unrealized losses relating to decreases in long-term forward LIBOR benchmark interest rates relative to the beginning of 2015.

During 2015, we recognized unrealized gains on our interest rate swap agreements associated with our Euro-denominated long-term debt. This resulted from transfers of $7.9 million of previously recognized unrealized losses to realized losses related to actual cash settlements of our interest rate swaps, and $2.2 million of unrealized gains relating to increases in long-term forward EURIBOR benchmark interest rates relative to the beginning of 2015.

The projected forward average tanker rates in the tanker market increased at December 31, 2015 compared to the beginning of 2015, which resulted in $1.6 million of unrealized losses on our Toledo Spirit time-charter derivative.

Please see “Item 5 – Operating and Financial Review and Prospects: Critical Accounting Estimates – Valuation of Derivative Instruments,” which explains how our derivative instruments are valued, including the significant factors and uncertainties in determining the estimated fair value and why changes in these factors result in material variances in realized and unrealized loss on non-designated derivative instruments.

Foreign Currency Exchange Gains. Foreign currency exchange gains were $5.3 million and $13.9 million for 2016 and 2015, respectively. These foreign currency exchange gains are due primarily to the relevant period-end revaluation of our NOK-denominated debt and our Euro-denominated term loans for financial reporting purposes into U.S. Dollars, net of the realized and unrealized gains and losses on our cross-currency swaps. Gains on NOK-denominated and Euro-denominated monetary liabilities reflect a stronger U.S. Dollar against the NOK and Euro on the date of revaluation or settlement compared to the rate in effect at the beginning of the period. Losses on NOK-denominated and Euro-denominated monetary liabilities reflect a weaker U.S. Dollar against the NOK and Euro on the date of revaluation or settlement compared to the rate in effect at the beginning of the period.



For 2016, foreign currency exchange gains (losses) included realized gains of $16.8 million on the repurchase of a portion our NOK bonds maturing in 2017, the transfer of $17.7 million of previously recognized unrealized losses to realized losses related to our cross-currency swaps associated with the NOK bond repurchase, unrealized gains of $11.2 million on our cross-currency swaps primarily due to appreciation of long-term NOK forward exchange rates and increases in long-term forward NIBOR benchmark interest rates relative to the beginning of 2016, and $5.4 million on the revaluation of our Euro-denominated cash, restricted cash and debt. These gains were partially offset by transfers of ($16.8) million of previously recognized unrealized gains to realized gains related to the repurchase of the NOK bonds in October 2016, ($17.7) million of realized losses related to the termination of our cross-currency swaps associated with the NOK bond repurchase, ($9.1) million realized losses on settlements of our cross-currency swaps and a ($2.2) million loss on the revaluation of our NOK-denominated debt.

For 2015, foreign currency exchange gains (losses) included the revaluation of our Euro-denominated cash, restricted cash and debt of $25.6 million and the revaluation of our NOK-denominated debt of $54.7 million. These gains were partially offset by realized losses of ($7.6) million on settlements of our cross-currency swaps and unrealized losses of ($57.8) million on our cross-currency swaps primarily due to depreciation of long-term NOK forward exchange rates relative to the beginning of 2015.

Income Tax Expense. Income tax expense decreased to $1.0 million for 2016, from $2.7 million for 2015, primarily as a result of additional income taxes in 2015 from the termination of obligations related to capital leases and refinancing in the Teekay Nakilat Joint Venture.

Other Comprehensive Income (Loss) (or OCI). OCI was $2.8 million in 2016 compared to $(0.6) million in 2015, due to changes in the valuation of interest rate swaps accounted for using hedge accounting within the consolidated Teekay Nakilat Joint Venture and certain of our equity accounted joint ventures. During 2016, we recognized unrealized gains on our interest rate swaps accounted for using hedge accounting relating to increases in long-term forward LIBOR benchmark interest rates, relative to the beginning of 2016. During 2015, we recognized unrealized losses on our interest rate swaps accounted for using hedge accounting relating to decreases in long-term forward LIBOR benchmark interest rates, relative to the beginning of 2015.
Liquidity and Cash Needs
Our business model is to employ the majority of our vessels on fixed-rate contracts primarily with large energy companies and their transportation subsidiaries. Our primary liquidity needs for 2018 though 2019 through 2020 include payment of our quarterly distributions, including payments of distributions on our common units and Series A and Series B Preferred Units, funding any common unit repurchases we may undertake, operating expenses, dry-docking expenditures, debt service costs, scheduled repayments of long-term debt, bank debt maturities committed capital expenditures and the funding of general working capital requirements. We anticipate that our primary sources of funds for our short-term liquidity needs will be cash flows from operations, proceeds from debt and capital lease financings proceeds from equity offerings, and dividends we expect to receive from our equity-accounted joint ventures. For 20182019 through 2019,2020, we expect that our existing liquidity, combined with the cash flow we expect to generate from our operations and receive as dividends from our equity-accounted joint ventures, will be sufficient to finance a portionthe majority of our liquidity needs, including the equity portion of our committed capital expenditures. Our remaining liquidity needs include the requirement to secure financing for an adequate portion of our committed capital expenditures, to refinance our loan facilities maturing in 2018 and 2019, to repay or refinance our NOK-denominated bonds due in 2018 and, possibly, to fund the potential tax exposure relating to the lease arrangements that the Teekay Nakilat Joint Venture had previously entered into (please read “Item 18 – Financial Statements: Note 13c – Commitments and Contingencies"). Please read “Item 18 – Financial Statements: Note 13b – Commitments and Contingencies” for information about required funding for 2018 through 2019.2020. We already have committed debt financing in place for the following vessels and projects: all three of our wholly-owned LNG carriers under construction (of which one was delivered to us in February 2018) that will be chartered to a wholly-owned subsidiary of Shell; our wholly-owned LNG carrier under conversion to a FSU for the Bahrain LNG Joint Venture;existing growth projects, including: our wholly-owned LNG carrier newbuilding to be chartered on a 13-year15-year charter contract with BP; the three vesselsto Yamal Trade Pte. Ltd. (which was delivered in January 2019); one LNG carrier under construction in the Pan Union Joint Venture (of which one(which was delivered in January 2018) two of the three LPG carrier newbuildings in the Exmar LPG Joint Venture (of which one was delivered in March 2018)2019); the sixall four ARC7 LNG carriers under construction for the Yamal LNG Joint Venture (of which one was delivered in January 2018);Venture; and the assets of the Bahrain LNG Joint Venture formed for the development of an LNG receiving and regasification terminal in Bahrain. We are in the process of securing debt financing for one LPG carrier newbuilding in the Exmar LPG Joint Venture which delivers in 2018, one wholly-owned LNG carrier under construction which delivers in 2019, and for the other requirements described above.

Our annual liquidity needs beyond 2018 are currently expected to decline compared to 2018, as a majority of our capital expenditure commitments relate to 2018. Our ability to continue to expand the size of our fleet over the long-termlong term is dependent upon our ability to generate operating cash flow, obtain long-term bank borrowings, sale-leaseback financing and other debt, as well as our ability to raise debt or equity financing through public or private offerings.

Our revolving credit facilities, term loans and obligations related to capital leases are described in the "Credit Facilities and Capital Leases" section below and in "Item 18 – Financial Statements: Note 5 – LeasesChartered-in Vessels and Note 910 – Long-Term Debt".Debt."

As at December 31, 2017,2018, our consolidated cash and cash equivalents were $244.2$149.0 million, compared to $126.1$244.2 million at December 31, 2016.2017. Our total liquidity, which consists of cash, cash equivalents and undrawn credit facilities, was $324.6 million as at December 31, 2018, compared to $433.6 million as at December 31, 2017, compared to $369.8 million as at December 31, 2016.2017. The increasedecrease in total consolidated liquidity was primarily due to proceedsfunding of our committed projects, including capital contributions into the Pan Union Joint Venture and Teekay LNG-Marubeni Joint Venture, and payment of the tax indemnification liability in our consolidated Teekay Nakilat Joint Venture during 2018. The decrease in total consolidated liquidity was partially offset by cash generated from our NOK bond issuance in January 2017,operations, proceeds from our sale-leaseback transactions completed during 2017,2018, proceeds from the issuancesales of the European Spirit and African Spirit and proceeds from the sale of our Series B Preferred Units in October 2017, and dividends and return of capital received from our equity-accounted joint ventures. These cash proceeds were partially offset by the repayment of NOK bonds in May 2017; funding of our committed projects, including advances and capital contributions50% ownership interest in the Bahrain LNGExcelsior Joint Venture, Yamal LNG Joint Venture and the Pan Union Joint Venture; and an equity contribution into the Teekay LNG-Marubeni Joint Venture upon completion of its debt refinancing in 2017.Venture.



As at December 31, 2017,2018, we had a working capital deficit of $484.6$32.8 million, which is primarily the result of: an aggregate amount of $236.9 million of our credit facilities being classified as current portion of long-term debt due to their maturity dates in mid-2018; $109.7 million of our NOK bonds being classified as current due to their maturity dates in September 2018; and $49.9includes $24.0 million of current obligations related to capital leases relating to two Suezmax tankers, underthe Toledo Spirit, which was sold by the owner has the option to require us to purchase the vessels. In February 2018, the owner sold the first vesselin January 2019 to a third party, and concurrently terminatedresulting in the charter contract with us. Similarly, we believe that the owner will not exercise its options to require us to purchase the second vessel, but rather we expect that the owner will cancel the charter contract relating to the second vessel when the cancellation right is first exercisable in August 2018 and sell the second vessel to a third party, upon whichextinguishment of the remaining lease obligations would be extinguishedobligation without any expected cash flow impact directly relating to such extinguishment (please read "Item 5 – Operating and Financial Review and Prospects: Management's Discussion and Analysis of Financial Condition and Results of Operations: Significant Developments in 2017 and Early 2018 - Conventional Tankers").extinguishment. We expect to manage our working capital deficit primarily with net operating cash flow and dividends from our equity-accounted joint ventures, debt refinancings, sale-leaseback financings, equity issuances such as our recent issuance of preferred units in 2017, and, to a lesser extent, existing undrawn revolving credit facilities. We do not have controlAs at December 31, 2018, we had undrawn revolving credit facilities of $175.6 million. Please read “Item 18 - Financial Statements: Note 14a - Commitments and Contingencies” for information about required funding over the operations, nor do we have any legal claim to the revenue and expenses of our equity-accounted joint ventures; consequently, the cash flow generated by our equity-accounted joint ventures may not be available for use by us in the period generated.next 12 months.

As described under “Item 4 – Information on the Partnership: B. Operations - Regulations,” passage of any climate control legislation or other regulatory initiatives that restrict emissions of greenhouse gases could have a significant financial and operational impact on our business, which we cannot predict with certainty at this time. Such regulatory measures could increase our costs related to operating and maintaining our vessels and require us to install new emission controls, acquire allowances or pay taxes related to our greenhouse gas emissions, or administer and manage a greenhouse gas emissions program. In addition, increased regulation of greenhouse gases may, in the long term, lead to reduced demand for oil and gas and reduced demand for our services.

Operating Cash Flows. Net cash flow from operating activities decreased to $131.2 million in 2018 from $218.8 million in 2017, primarily due to the payment of the tax indemnification liability in our consolidated Teekay Nakilat Joint Venture; decrease in cash flows from our seven multi-gas carriers; decrease in cash flows from our two conventional tankers trading in the spot market and then sold in 2018; the Polar Spirit earning a lower time-charter rate upon redeployment; the sales of the Asian Spirit and Teide Spirit conventional tankers in March 2017 and February 2018, respectively; and decrease in dividends received from our equity-accounted joint ventures. These decreases were partially offset by an increase in cash flows generated by the deliveries to us of the Torben Spirit, Macoma, Murex, Magdala, Myrina, Megara, Bahrain Spirit and Sean Spirit LNG carriers between February 2017 and December 2018 and the Magellan Spirit chartered-in from the Teekay LNG-Marubeni Joint Venture commencing its charter-out employment in October 2018.

Net cash flow from operating activities increased to $194.5$218.8 million in 2017 from $166.5$194.4 million in 2016, primarily due to the deliveries of our LNG carrier newbuildings and commencement of their charter contracts during 2016 and 2017; an increase in the amount of dividends received from our equity-accounted joint ventures; six days of scheduled off-hire during the first quarter of 2016 due to an in-water survey for the Catalunya Spirit; and the timing of settlement of advances to and from affiliates. These increases were partially offset by the sales of the Bermuda Spirit, Hamilton Spirit and Asian Spirit in April 2016, May 2016 and March 2017, respectively; reduced revenues in 2017 for uncollected hire invoices relating to our six LPG carriers on charter to Skaugen; 35 days of unscheduled off-hire in the second quarter of 2017 due to repairs required for one of our LNG carriers; the Hispania Spirit being off-hire for 31 days in the first quarter of 2017 for a scheduled dry docking; lower spot rates earned by the European Spirit and African Spirit after their fixed-rate charter contracts expired in August and November 2017, respectively; an increased amount of dry-docking expenditures in 2017; and one additional calendar day in the first quarter of 2016.

Net cash flow from operating activities decreased to $166.5 million in 2016 from $239.7 million in 2015, primarily due to a lower aggregate amount of dividends received from our equity-accounted joint ventures, the sales of the Bermuda Spirit and Hamilton Spirit in April 2016 and May 2016, respectively, an increase in restricted cash relating to operating activities, reduced revenues in the fourth quarter of 2016 for uncollected hire invoices relating to our six LPG carriers on charter to Skaugen, lower revenues earned by the Teide Spirit relating to the profit-sharing agreement between us and CEPSA, and lower charter rates on the European Spirit, African Spirit and Asian Spirit. These decreases were partially offset by the commencement of charter contracts for the Creole Spirit and Oak Spirit in February 2016 and August 2016, respectively, fewer off-hire days relating to scheduled dry dockings during 2016, the timing of collection and payments owing from and to our affiliates, and one additional calendar day in 2016.

Net cash flow from operating activities depends upon the timing and amount of dry-docking expenditures, repair and maintenance activity, the impact of vessel additions and dispositions on operating cash flows, foreign currency rates, changes in interest rates, timing and amounts of dividends received from equity-accounted investments, fluctuations in working capital balances and spot market hire rates (to the extent we have vessels operating in the spot tanker market or our hire rates are partially affected by spot market rates). The number of vessel dry dockings tends to vary each period depending on the vessels’ maintenance schedule.

Our equity-accounted joint ventures are generally required to distribute all available cash to their owners. However, the timing and amount of dividends from each of our equity-accounted joint ventures may not necessarily coincide with the operating cash flow generated from each respective equity-accounted joint venture. The timing and amount of dividends distributed by our equity-accounted joint ventures are affected by the timing and amounts of debt repayments in the joint ventures, capital requirements of the joint ventures, as well as any cash reserves maintained in the joint ventures for operations, capital expenditures and/or as required under financing agreements.

Financing Cash Flows. Net cash flow from financing activities decreased to $385.1 million in 2018 from $644.0 million in 2017 primarily due to an increase in debt prepayments and repayments including settlement of related swaps of $540.8 million primarily in relation to completion of refinancings during 2018; $370.1 million of net proceeds we received from the sale-leaseback financing transactions for the deliveries of the Magdala, Myrina and Megara during 2018, compared to $656.9 million in 2017; $164.4 million increase in net proceeds from equity offerings due to the issuance of our Series B Preferred Units in October 2017; increase in repayments of obligations related to capital leases of $17.7 million due to sale-leaseback financing transactions completed during 2018 and 2017; a $13.7 million increase in cash distributions paid as a result of the issuance of our Series B Preferred Units in October 2017; and $3.8 million used to repurchase common units during 2018. These decreases in cash flows from financing activities were partially offset by a $769.2 million increase in net proceeds from the issuance of long-term debt for refinancings completed in 2018 and the timing of drawdowns on certain of our existing debt facilities.


Net cash flow from financing activities increased to $690.1$644.0 million in 2017 from $200.4$178.0 million in 2016 primarily as a result of: a total of $374.9$366.9 million in lower debt prepayments and repayments as the term loans associated with the sales of the Bermuda


Spirit and Hamilton Spirit were prepaid in 2016; an increase of $301.6 million in proceeds from the sale-leaseback financing transactions completed on our LNG carrier newbuildings during 2017; and $43.7 million higher net proceeds from equity offerings due to the issuance of our Series B Preferred Units in October 2017; and a decrease in restricted cash of $15.7 million primarily due to changes in the amount of margin call collateral related to our NOK cross-currency swaps.2017. These increases in cash flows from financing activities were partially offset by: a $215.9 million decrease in net proceeds from the issuance of long-term debt, primarily due to the timing of drawdowns on certain of our existing debt facilities; a $20.4 million increase in capital lease repayments during 2017 due to the sale-leaseback financing transactions completed in 2016 and 2017; and a $11.2 million increase in cash distributions paid as a result of the issuance of our Series A Preferred Units in October 2016.

Investing Cash Flows.Net cash flow used for investing activities increased to $766.4 million in 2017 compared to $343.2 million in 2016. During 2017, we used $708.6 million in cash, primarily for scheduled newbuilding installment payments and shipbuilding supervision costs for our LNG carrier newbuildings compared to $345.8 million during 2016; in March 2017, we received $20.6 million in proceeds from the sale of the Asian Spirit, compared to $94.3 million from the sales of the Bermuda Spirit and Hamilton Spirit in April 2016 and May 2016, respectively; we contributed $183.9 million to our equity-accounted joint ventures in 2017 compared to $120.9 million during 2016, primarily to fund newbuilding installments in the Yamal LNG Joint Venture and project expenditures for the Bahrain LNG project; and during 2017, our receipts from direct financing leases were decreased by $10.5 million, primarily due to our lease payment deferral agreement with Awilco. These increases in cash used for investing activities were partially offset by $40.3 million and $52.0 million returns of capital we received in 2017 from the RasGas 3 Joint Venture and the Yamal LNG Joint Venture, respectively, upon completion of their debt refinancings, compared to $5.5 million of distributions we received during 2016 as a repayment of a shareholder loan from the Exmar LPG Joint Venture.

Net cash flow used for investing activities increased to $343.2 million in 2016 compared to $212.5 million in 2015. During 2016, we used $345.8 million for capital expenditures, primarily for scheduled newbuilding installment payments and shipbuilding supervision costs for our LNG carrier newbuildings, compared to $192.0 million in 2015. During 2016, we contributed $120.9 million to our equity-accounted joint ventures in 2016 compared to $25.9 million in 2015, primarily to fund newbuilding installments in the Yamal LNG Joint Venture and project expenditures for the Bahrain LNG project. During 2016, we received a $5.5 million repayment of a shareholder loan from the Exmar LPG Joint Venture, compared to a $23.7 million repayment of a shareholder loan from the Exmar LPG Joint Venture during 2015. These increases in cash flow used for investing activities in 2016 were partially offset by $94.3 million in proceeds received from the sales of the Bermuda Spirit and Hamilton Spirit in April 2016 and May 2016, respectively, and an increase of $7.8 million in receipts from direct financing leases due to the timing of payments. There was no change in the amount of the $34.3 million relating to a performance bond placed in 2015 on the Bahrain LNG Joint Venture project.

Credit Facilities and Capital Leases
Our revolving credit facilities, term loans and obligations related to capital leases are described in "Item 18 – Financial Statements: Note 5 – LeasesChartered-in Vessels and Note 910 – Long-Term Debt." Our term loans, revolving credit facilities and obligations related to capital leases contain covenants and other restrictions typical of debt financing secured by vessels, including, among others, one or more of the following that restrict the ship-owning subsidiaries from:

incurring or guaranteeing indebtedness;
changing ownership or structure, including mergers, consolidations, liquidations and dissolutions;
making dividends or distributions if we are in default;
making capital expenditures in excess of specified levels;
making certain negative pledges and granting certain liens;
selling, transferring, assigning or conveying assets;
making certain loans and investments; and
entering into a new line of business.



Certain loan agreements require (a) that minimum levels of tangible net worth and aggregate liquidity be maintained, (b) that we maintain certain ratios of vessel values as it relates to the relevant outstanding loan principal balance, (c) that we do not exceed a maximum amount of leverage and (d) certain of our subsidiaries to maintain restricted cash deposits. As at December 31, 2017,2018, we had twothree facilities with an aggregate outstanding loan balance of $90.6$442.2 million that require us to maintain minimum vessel-value-to-outstanding-loan-principal-balance ratios ranging from 110%115% to 135%, which as at December 31, 20172018 ranged from 126%132% to 243%198%. The vessel values were determined using a currentused in calculating these ratios are the appraised values provided by third parties where available or prepared by us based on second-hand sale and purchase market value for comparable second-hand vessels.data. Since vessel values can be volatile, our estimate of market value may not be indicative of either the current or future price that could be obtained if the related vessel was actually sold. Our ship-owning subsidiaries may not, among other things, pay dividends or distributions if they are in default under their term loans or revolving credit facilities.facilities and one of the term loans in the Teekay Nakilat Joint Venture requires it to satisfy a minimum vessel value to outstanding loan principal balance ratio to pay dividends. In addition, we guarantee thecertain obligations related to capital leases, which require us to maintain minimum levels of tangible net worth and aggregate liquidity, and not to exceed a maximum amount of leverage. As at December 31, 2017,2018, we and our affiliates were in compliance with all covenants relating to our credit facilities and capital leases.

Off-Balance Sheet Arrangements
We have no off-balance sheet arrangements that have or are reasonably likely to have, a current or future material effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources. The details of our equity-accounted investments are shown in "Item 18 – Financial Statements: Note 67 – Equity-Accounted Investments."
Critical Accounting Estimates
We prepare our consolidated financial statements in accordance with GAAP, which requires us to make estimates in the application of our accounting policies based on our best assumptions, judgments and opinions. On a regular basis, management reviews the accounting policies, assumptions, estimates and judgments to ensure that our consolidated financial statements are presented fairly and in accordance with GAAP. However, because future events and their effects cannot be determined with certainty, actual results could differ from our assumptions and estimates, and such differences could be material. Accounting estimates and assumptions discussed in this section are those that we consider to be the most critical to an understanding of our financial statements, because they inherently involve significant judgments and uncertainties. For a further description of our material accounting policies, please read “Item 18 – Financial Statements: Note 1 – Summary of Significant Accounting Policies.”
Vessel Lives and Impairment
Description. The carrying value of each of our vessels represents its original cost at the time of delivery or purchase less depreciation and impairment charges. We depreciate the original cost, less an estimated residual value, of our vessels on a straight-line basis over each vessel’s estimated useful life. The carrying values of our vessels may not represent their market value at any point in time because the market prices of second-hand vessels tend to fluctuate with changes in charter rates and the cost of newbuildings. Both charter rates and newbuilding costs tend to be cyclical in nature.

We review vessels and equipment for impairment whenever events or circumstances indicate the carrying value of an asset, including the carrying value of the charter contract, if any, under which the vessel is employed, may not be recoverable. This occurs when the asset’s carrying value is greater than the future undiscounted cash flows the asset is expected to generate over its remaining useful life. For a vessel under charter, the discounted cash flows from that vessel may exceed its market value, as market values may assume the vessel is not employed on an existing charter. If the estimated future undiscounted cash flows of an asset exceed the asset’s carrying value, no impairment is recognized even though the fair value of the asset may be lower than its carrying value. If the estimated future undiscounted cash flows of an asset isare less than the asset’s carrying value and the fair value of the asset is less than its carrying value, the asset is written down to its fair value. Fair value is calculated as the net present value of estimated future cash flows, which, in certain circumstances, will approximate the estimated market value of the vessel.

Our business model is to employ our vessels on fixed-rate contracts primarily with large energy companies and their transportation subsidiaries. These contracts generally have original terms between five to 25 years in length. Consequently, while the market value of a vessel may decline


below its carrying value, the carrying value of a vessel may still be recoverable based on the future undiscounted cash flows the vessel is expected to obtain from servicing its existing contract and future contracts.

The following table presents by segment the aggregate market values and carrying values of certain of our vessels that we have determined have a market value that is less than their carrying value as of December 31, 2017.2018. Specifically, the following table reflects all such vessels, except those operating on contracts where the remaining term is significant and the estimated future undiscounted cash flows relating to such contracts are sufficiently greater than the carrying value of the vessels such that we consider it unlikely an impairment would be recognized in the following year. Consequently, the vessels included in the following table generally include those vessels near the end of existing charters or other operational contracts. While the market values of these vessels are below their carrying values, no impairment has been recognized on any of these vessels as the estimated future undiscounted cash flows relating to such vessels are greater than their carrying values.

We would consider the vessels reflected in the following table to be at a higher risk of future impairment. The estimated future undiscounted cash flows of the vessels reflected in the following table are significantly greater than their respective carrying values. Consequently, in these cases, the following table would not necessarily represent vessels that would likely be impaired in the next 12 months, and the recognition of an impairment in the future for any of those vessels may primarily depend upon our deciding to dispose of thea vessel instead of continuing to operate it. In deciding whether to dispose of a vessel, we determine whether it is economically preferable to sell thea vessel or continue to operate it. This assessment includes an estimate of the net proceeds expected to be received if thea vessel is sold in its existing condition compared to the present value of the vessel’s estimated future revenue, net of operating costs. Such estimates are based on the terms of theits existing charter, charter market outlook and estimated operating costs, given a vessel’s type, condition and age. In addition, we typically do not dispose of a vessel that is servicing an existing customer contract.

(1)Market values are determined using reference to second-hand market comparable values as at December 31, 2017.2018. Since vessel values can be volatile, our estimates of market value may not be indicative of either the current or future prices we could obtain if we sold any of the vessels.
(2)Undiscounted cash flows are significantly greater than the carrying values.

Judgments and Uncertainties. Depreciation is calculated using an estimated useful life of 25 years for conventional tankers, 30 years for LPG Carriers and 35 years for LNG carriers, commencing at the date the vessel was originally delivered from the shipyard. However, the actual life of a vessel may be different than the estimated useful life, with a shorter actual useful life resulting in an increase in the quarterly depreciation and potentially resulting in an impairment loss. The estimated useful life of our vessels takes into account design life, commercial considerations and regulatory restrictions. Our estimates of future cash flows involve assumptions about future charter rates, vessel utilization, operating expenses, dry-docking expenditures, vessel residual values and the remaining estimated life of our vessels. Our estimated charter rates are based on rates under existing vessel contracts and market rates at which we expect we can re-charter our vessels. Our estimates of vessel utilization, including estimated off-hire time, are based on historical experience. Our estimates of operating expenses and dry-docking expenditures are based on historical operating and dry-docking costs and our expectations of future inflation and operating requirements. Vessel residual values are a product of a vessel’s lightweight tonnage and an estimated scrap rate. The remaining estimated lives of our vessels used in our estimates of future cash flows are consistent with those used in the calculation of depreciation.

Certain assumptions relating to our estimates of future cash flows are more predictable by their nature in our historical experience, including estimated revenue under existing contract terms, on-going operating costs and remaining vessel life. Certain assumptions relating to our estimates of future cash flows require more discretion and are inherently less predictable, such as future charter rates beyond the firm period of existing contracts and vessel residual values, due to factors such as the volatility in vessel charter rates and vessel values. We believe that the assumptions used to estimate future cash flows of our vessels are reasonable at the time they are made. We can make no assurances, however, as to whether our estimates of future cash flows, particularly future vessel charter rates or vessel values, will be accurate.

Effect if Actual Results Differ from Assumptions. If we conclude that a vessel or equipment is impaired, we recognize a loss in an amount equal to the excess of the carrying value of the asset over its fair value at the date of impairment. The written-down amount becomes the new lower cost basis and will result in a lower annual depreciation expense than forin periods beforesubsequent to the vessel impairment. Consequently, any changes in our estimates of future undiscounted cash flows may result in a different impairment amount, including no impairment, and a different future annual depreciation expense.
Dry-docking Life
Description. We capitalize a portion of the costs we incur during dry docking and for an intermediate survey and amortize those costs on a straight-line basis over the useful life of the dry dock. We expense costs related to routine repairs and maintenance incurred during dry docking that do not improve operating efficiency or extend the useful lives of the assets.

Judgments and Uncertainties. Amortization of capitalized dry-dock expenditures requires us to estimate the period of the next dry docking and useful life of dry-dock expenditures. While we typicallygenerally dry dock each vessel every two and a half to five years, and have a shipping society classification intermediate survey performed on our LNG and LPG carriers between the second and third year of the five-year dry-docking period, we may dry dock the vessels at an earlier date, with a shorter life resulting in an increase in the amortization.amortization expense.



Effect if Actual Results Differ from Assumptions. If we change our estimate of the next dry-dock date for a vessel, we will adjust our annual amortization of dry-docking expenditures. Amortization expense of capitalized dry-dock expenditures for 2018, 2017, and 2016 and 2015 were $11.6 million, $13.9 million, and $11.5 million, and $10.1 million, respectively. As atFor the years ended December 31, 2018, 2017, 2016, and 2015,2016, our capitalized dry-dock expenditures were$22.3were $15.3 million, $13.9$22.3 million, and $10.4$13.9 million, respectively. A one-year reduction in the estimated useful lives of capitalized dry-dock expenditures would result in an increase in our current annual amortization by approximately $2.8$3.4 million.
Goodwill and Intangible Assets
Description. We allocate the cost of acquired companies, including acquisitions of equity-accounted investments, to the identifiable tangible and intangible assets and liabilities acquired, with the remaining amount being classified as goodwill. Certain intangible assets, such as time-charter contracts, are being amortized over time. Our future operating performance will be affected by the amortization of intangible assets and potential impairment charges related to goodwill and intangibles. Accordingly, the allocation of purchase price to intangible assets and goodwill may significantly affect our future operating results.

Goodwill is not amortized but is reviewed for impairment at the reporting unit level on an annual basis or more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit to below its carrying value. When goodwill is reviewed for impairment, we may elect to assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. Alternatively, we may bypass this step and use a fair value approach to identify potential goodwill impairment and, when necessary, measure the amount of impairment. The Partnership uses a discounted cash flow model to determine the fair value of reporting units, unless there is a readily determinable fair market value. Intangible assets are assessed

for impairment when and if impairment indicators exist. An impairment loss is recognized if the carrying amount of an intangible asset is not recoverable and its carrying amount exceeds its fair value.

Judgments and Uncertainties. The allocation of the purchase price of acquired companies to intangible assets and goodwill requires management to make significant estimates and assumptions, including estimates of future cash flows expected to be generated by the acquired assets and the appropriate discount rate to value these cash flows. In addition, the process of evaluating the potential impairment of goodwill and intangible assets is highly subjective and requires significant judgment at many points during the analysis. The fair value of our reporting units was estimated based on discounted expected future cash flows using a weighted-average cost of capital rate. The estimates and assumptions regarding expected cash flows and the discount rate require considerable judgment and are based upon existing contracts, historical experience, financial forecasts and industry trends and conditions.

At December 31, 2017,2018, we had onetwo reporting unitunits with goodwill attributable to it. Asthem, and we recorded an impairment charge of $0.8 million during the year relating to a portion of the date of this filing, we do not believe that there is a reasonable possibility that the goodwill attributableattributed to this reporting unit might be impaired within the next year. However, certainour liquefied petroleum gas segment. Certain factors that impact this assessmentthese assessments are inherently difficult to forecast and as such we cannot provide any assurances that an impairment will or will not occur in the future. An assessment for impairment involves a number of assumptions and estimates that are based on factors that are beyond our control. These are discussed in more detail in Part I – Forward-Looking Statements.

Amortization expense of intangible assets for each of the years 2018, 2017, 2016, and 20152016 was $8.9 million $8.9 million, and $8.9 million, respectively.per year. If actual results are not consistent with our estimates used to value our intangible assets, we may be exposed to an impairment charge and a decrease in the annual amortization expense of our intangible assets.
Valuation of Derivative Instruments
Description. Our risk management policies permit the use of derivative financial instruments to manage interest rate risk, foreign exchange risk and spot tanker market risk. Changes in fair value of derivative financial instruments that are not designated as cash flow hedges for accounting purposes are recognized in earnings.

Judgments and Uncertainties. A substantial majority of the fair value of our derivative instruments and the change in fair value of our derivative instruments from period to period result from our use of interest rate swap agreements. The fair value of our derivative instruments is the estimated amount that we would receive or pay to terminate the agreements at the reporting date, taking into account current interest rates and the current credit worthiness of both us and the swap counterparties. The estimated amount is the present value of estimated future cash flows, being equal to the difference between the benchmark interest rate and the fixed rate in the interest rate swap agreement, multiplied by the notional principal amount of the interest rate swap agreement at each interest reset date.

The fair value of our interest and cross-currencycross currency swap agreements at the end of each period is most significantly affected by the interest rate implied by the benchmark interest yield curve, including its relative steepness, and forward foreign exchange rates. Interest rates and foreign exchange rates have experienced significant volatility in recent years in both the short and long term. While the fair value of our interest and cross-currencycross currency swap agreements is typically more sensitive to changes in short-term rates, significant changes in the long-term benchmark interest and foreign exchange rates also materially impact our interest and cross-currencycross currency swap agreements.

The fair value of our interest and cross-currencycross currency swap agreements is also affected by changes in our specific credit risk included in the discount factor. We discount our interest rate swap agreements with reference to the credit default swap spreads of similarly rated global industrial companies and by considering any underlying collateral. The process of determining credit worthiness requires significant judgment in determining which source of credit risk information most closely matches our risk profile.



The benchmark interest rate yield curve and our specific credit risk are expected to vary over the life of the interest rate swap agreements. The larger the notional amount of the interest rate swap agreements outstanding and the longer the remaining duration of the interest rate swap agreements, the larger the impact of any variability in these factors will be on the fair value of our interest rate swaps. We economically hedge the interest rate exposure on a significant amount of our long-term debt and for long durations. As such, we have historically experienced, and we expect to continue to experience, material variations in the period-to-period fair value of our derivative instruments.

The fair value of our derivative instrument relating to the agreement between us and Teekay Corporation for the Toledo Spirittime-charter contract is the estimated amount that we would receive or pay to terminate the agreement at the reporting date. This amount is estimated using the present value of our projected future spot market tanker rates, which has been derived from current spot market rates and long-term historical average rates.

Effect if Actual Results Differ from Assumptions. Although we measure the fair value of our derivative instruments utilizing the inputs and assumptions described above, if we were to terminate the agreements at the reporting date, the amount we would pay or receive to terminate the derivative instruments may differ from our estimate of fair value. If the estimated fair value differs from the actual termination amount, an adjustment to the carrying amount of the applicable derivative asset or liability would be recognized in earnings for the current period. Such adjustments could be material. See “Item 18 – Financial Statements: Note 1213 – Derivative Instruments and Hedging Activities” for the effects on the change in fair value of our derivative instruments on our consolidated statements of income and statements of comprehensive income.
Taxes
Description. We record a valuation allowance to reduce our deferred tax assets to the amount that is more likely than not to be realized.

Judgments and Uncertainties. The future realization of deferred tax assets depends on the existence of sufficient taxable income of the appropriate character in either the carryback or carryforward period. This analysis requires, among other things, the use of estimates and projections in determining future reversals of temporary differences, forecasts of future profitability and evaluating potential tax-planning strategies.

Effect if Actual Results Differ from Assumptions. If we determined that we were able to realize a net deferred tax asset in the future, in excess of the net recorded amount, an adjustment to the deferred tax assets would typically increase our net income in the period such determination was made. Likewise, if we determined that we were not able to realize all or a part of our deferred tax asset in the future, an adjustment to the deferred tax assets would typically decrease our net income in the period such determination was made. As at December 31, 2017,2018, we had recorded valuation allowances of $38.6$52.6 million (2016(December 31, 2017$41.1$38.6 million).

Crewing and Staff
As of December 31, 2017,2018, approximately 1,8001,900 seagoing staff served on our consolidated and equity-accounted for vessels that were managed by subsidiaries of Teekay Corporation and nine staff served on-shore in technical, commercial and administrative roles in various countries, compared to approximately 1,800 seagoing staff and nine on-shore staff as of December 31, 2017 and approximately 1,700 seagoing staff and nine on-shore staff as of December 31, 2016 and approximately 1,800 seagoing staff and 11 on-shore staff as of December 31, 2015.2016. Certain subsidiaries of Teekay Corporation employ the crews, who serve on the vessels pursuant to agreements with the subsidiaries, and Teekay Corporation subsidiaries also provide on-shore advisory, operational and


administrative support to our operating subsidiaries pursuant to service agreements. Please read “Item 7 – Major Common Unitholders and Related Party Transactions.”



We regard attracting and retaining motivated seagoing personnel as a top priority. Like Teekay Corporation, we offer our seafarers competitive employment packages and comprehensive benefits and opportunities for personal and career development, which relates to a philosophy of promoting internally.

Teekay Corporation has entered into a Collective Bargaining Agreement with the Philippine Seafarers’ Union, an affiliate of the International Transport Workers’ Federation (or ITF), and a Special Agreement with ITF London, which cover substantially all of the officers and seamenseafarers that operate our Bahamian-flagged vessels. Our Spanish officers and seamenseafarers for our Spanish-flagged vessels are covered by two different collective bargaining agreements (one for Suezmax tankers and one for LNG carriers) with Spain’s Union General de Trabajadores and Comisiones Obreras, and the Filipino crewmembers employed on our Spanish-flagged LNG and Suezmax tankers are covered by the Collective Bargaining Agreement with the Philippine Seafarer’s Union. We believe Teekay Corporation’s and our relationships with these labor unions are good.

Our commitment to training is fundamental to the development of the highest caliber of seafarers for our marine operations. Teekay Corporation has agreed to allow our personnel to participate in its training programs. Teekay Corporation’s cadet training approach is designed to balance academic learning with hands-on training at sea. Teekay Corporation has relationships with training institutions in Canada, Croatia, India, Latvia, Norway, Philippines, Turkey and the United Kingdom. After receiving formal instruction at one of these institutions, our cadets’ training continues on boardon-board one of our vessels. Teekay Corporation also has a career development plan that we follow, which was designed to ensure a continuous flow of qualified officers who are trained on its vessels and familiarized with its operational standards, systems and policies. We believe that high-quality crewing and training policies will play an increasingly important role in distinguishing larger independent shipping companies that have in-house or affiliate capabilities from smaller companies that must rely on outside ship managers and crewing agents on the basis of customer service and safety. As such, we have aan LNG training facility in Glasgow that serves this purpose.

Related Party Transactions
a)We have entered into an amended and restated omnibus agreement with Teekay Corporation, our General Partner, our operating company, Teekay LNG Operating L.L.C.,Opco, Teekay Offshore and related parties. The following discussion describes certain provisions of the omnibus agreement.agreement, as it has been amended.

Noncompetition. Under the omnibus agreement, Teekay Corporation and Teekay Offshore have agreed, and have caused their controlled affiliates (other than us) to agree, not to own, operate or charter LNG carriers. This restriction does not prevent Teekay Corporation, Teekay Offshore or any of their controlled affiliates (other than us) from, among other things:

acquiring LNG carriers and related time-charters as part of a business and operating or chartering those vessels if a majority of the value of the total assets or business acquired is not attributable to the LNG carriers and related time-charters, as determined in good faith by the board of directors of Teekay Corporation or the conflicts committee of the board of directors of Teekay Offshore’s general partner; however, if at any time Teekay Corporation or Teekay Offshore completes such an acquisition, it must offer to sell the LNG carriers and related time-charters to us for their fair market value plus any additional tax or other similar costs to Teekay Corporation or Teekay Offshore that would be required to transfer the LNG carriers and time-charters to us separately from the acquired business;
owning, operating or chartering LNG carriers that relate to a bid or award for a proposed LNG project that Teekay Corporation or any of its subsidiaries has submitted or hereafter submits or receives; however, at least 180 days prior to the scheduled delivery date of any such LNG carrier, Teekay Corporation must offer to sell the LNG carrier and related time-charter to us, with the vessel valued at its “fully-built-up cost,” which represents the aggregate expenditures incurred (or to be incurred prior to delivery to us) by Teekay Corporation to acquire or construct and bring such LNG carrier to the condition and location necessary for our intended use, plus a reasonable allocation of overhead costs related to the development of such project and other projects that would have been subject to the offer rights set forth in the omnibus agreement but were not completed; or
things, acquiring, operating or chartering LNG carriers if our General Partner has previously advised Teekay Corporation or Teekay Offshore that the boardBoard of directorsDirectors of our General Partner has elected, with the approval of its conflicts committee, not to cause us or our subsidiaries to acquire or operate the carriers.

In addition, under the omnibus agreement we have agreed not to own, operate or charter crude oil tankers or the followingcertain “offshore vessels” – dynamically positioned(including dynamically-positioned shuttle tankers, floating storage and off-take units or floating production, storage and off-loading units, in each case thatunits), if they are subject to contracts with a remaining duration of at least three years, excluding extension options. This restriction does not apply to any of the conventional tankers in our current fleet, and the ownership, operation or chartering of any oil tankers that replace any of those oil tankers in connection with certain events. In addition, the restriction does not prevent us from, among other things:

acquiring oil tankers or offshore vessels and any related time-charters or contracts of affreightment as part of a business and operating or chartering those vessels, if a majority of the value of the total assets or business acquired is not attributable to the oil tankers and offshore vessels and any related charters or contracts of affreightment, as determined by the conflicts committee of our General


Partner’s board of directors; however, if at any time we complete such an acquisition, we are required to promptly offer to sell to Teekay Corporation the oil tankers and time-charters or to Teekay Offshore the offshore vessels and time-charters or contracts of affreightment for fair market value plus any additional tax or other similar costs to us that would be required to transfer the vessels and contracts to Teekay Corporation or Teekay Offshore separately from the acquired business; or
things,acquiring, operating or chartering oil tankers or offshore vessels if Teekay Corporation or Teekay Offshore, respectively,as applicable, has previously advised our General Partner that it has elected not to acquire or operate those vessels.

Rights of First Offer on Suezmax Tankers, LNG Carriers and Offshore Vessels. Under the omnibus agreement, we have granted to Teekay Corporation and Teekay Offshore a 30-day right of first offer on any proposed (a) sale, transfer or other disposition of any of our conventional tankers, in the case of Teekay Corporation, or certain offshore vessels in the case of Teekay Offshore, or (b) re-chartering of any of our conventional tankers or offshore vessels pursuant to a time-charter or contract of affreightment with a term of at least three years if the existing charter expires or is terminated early. Likewise, each of Teekay Corporation and Teekay Offshore has granted a similar right of first offer to us for any LNG carriers it might own. These rights of first offer do not apply to certain transactions.

Termination. If Teekay Corporation or its affiliates no longer control our General Partner or the general partner of Teekay Offshore or if there is a change of control of Teekay Corporation, our General Partner, the general partner of Teekay Offshore or Teekay Corporation, then any of those entities, as applicable, may terminate relevant noncompetition and rights of first offer provisions of the omnibus agreement. During 2018, Brookfield Business Partners L.P. and its institutional investors acquired a 51% ownership interest in the general partner of Teekay Offshore and have the right to appoint a majority of the directors of Teekay Offshore's general partner’s Board of Directors. This transaction constituted a change of control, giving Teekay Offshore the right to elect to terminate the omnibus agreement, though we have not received any indication from Teekay Offshore that it intends to do so.

Mr. Utt also is the Chair of Teekay Corporation and a member of the Board of Directors of the general partner of Teekay Offshore. Mr. Hvid is also the President and Chief Executive Officer of Teekay Corporation, the Chief Executive Officer and Chief Financial Officera director of Teekay Offshore GP L.L.C. and Teekay GP L.L.C.Tankers Ltd., and a Directorpublicly-traded subsidiary of Teekay Corporation, and a member of the Board of Directors of the general partner of Teekay GP L.L.C.Offshore.

Mr. Day will retire from Teekay Corporation's Board of Directors in June 2019, but will continue to serve on the Board of our General Partner.

Legal Proceedings
From time to time we have been, and expect to continue to be, subject to legal proceedings and claims in the ordinary course of our business, principally personal injury and property casualty claims. These claims, even if lacking merit, could result in the expenditure of significant financial and managerial resources. We are not aware of any legal proceedings or claims that we believe will have, individually or in the aggregate, a material adverse effect on us, other than those set forth in "Item 18. -18 – Financial Statements: Notes 13c and 13d -Note 14 – Commitments and Contingencies".Contingencies."
Cash Distribution Policy for Common Unitholders
Rationale for Our Cash Distribution Policy
Our general cash distribution policy reflects a basic judgment that our common unitholders are better served by allocating capital in a balanced manner, including our distributingintention to increase our cash available after expenses and reserves rather than our retaining it. However,quarterly common unit distributions by 36 percent to $0.19 per unit, commencing with our distribution on common units relating to the fourthfirst quarter of 2015, we significantly reduced the amount2019 distribution to be paid in May 2019. This level of our quarterly per common unit distributions allows us to establish cash distributions. Global crude oil prices have significantly declined since mid-2014 and that decline has contributed to depressed natural gas prices. These declines in energy prices, combined with other factors beyond our control, adversely affected energy and master limited partnership capital markets and available sourcesreserves for the purpose of financing. Based on capital requirements forfunding committed growth projects and scheduled debt repayment obligations, coupled with weakness in the energy and master limited partnership capital markets, the board of directors of our General Partner believes it is in the best interests of our unitholders to retain more of our internally generated cash flows to fund these projects and to reduce debt levels. As a result, in December 2015, we reduced our quarterly distributions on our common units. This reduction in the amount of common unit distributions to establish cash reserves for these purposeslevels and is consistent with our cash distribution policy and the terms of our partnership agreement, which requiresrequire that we distribute all of our Available Cash (as defined in our partnership agreement) within approximately 45 days after the end of each quarter. Available Cash is determined after payment of distributions on our preferred units.
Limitations on Cash Distributions andDistributions; Our Ability to Change Our Cash Distribution Policy
There is no guarantee that common unitholders will receive quarterly distributions from us. Our distribution policy is subject to certain restrictions and may be changed at any time and is subject to certain restrictions, including:

Our common unitholders have no contractual or other legal right to receive distributions other than the obligation under our partnership agreement to distribute Available Cash on a quarterly basis, which is subject to our General Partner’s broad discretion to establish reserves (including, among others, reserves for future capital expenditures and our anticipated future credit needs) and other limitations (including as required by law, credit facilities or other agreements or obligations).
While our partnership agreement requires us to distribute all of our Available Cash, our partnership agreement, including provisions requiring us to make cash distributions contained therein, may be amended with the approval of a majority of the outstanding common units.
Even if our cash distribution policy is not modified or revoked, the amount of distributions we pay under our cash distribution policy and the decision to make any distribution is determined by the boardBoard of directorsDirectors of our General Partner, taking into consideration the terms of our partnership agreement.
Under Section 51 of The Marshall Islands Limited Partnership Act, we may not make a distribution to unitholders to the extent that at the time of the distribution, after giving effect to the distribution, all of our liabilities, other than liabilities to partners on account of their partnership interests and liabilities for which the recourse of creditors is limited to specified property of ours, exceed the fair value of our assets, except that the fair value of property that is subject to a liability for which the recourse of creditors is limited shall be included in our assets only to the extent that the fair value of that property exceeds that liability.
We may lack sufficient cash to pay distributions to our unitholders due to decreases in net revenues or increases in our operating expenses, principal and interest payments on outstanding debt, tax expenses, working capital requirements, maintenance capital expenditures or anticipated cash needs.
Our distribution policy may be affected by restrictions on distributions under our credit facility agreements, which contain material financial tests and covenants that must be satisfied and complied with. ShouldIf we beare unable to satisfy these restrictions included in our credit agreements or if we are otherwise in default under our credit agreements, we would be prohibited from making cash distributions, which would materially hinder our ability to make cash distributions to unitholders, notwithstanding our stated cash distribution policy.
If we make distributions out of capital surplus, as opposed to operating surplus (as such terms are defined in our partnership agreement), those distributions will constitute a return of capital and will result in a reduction in the minimum quarterly distribution and the target distribution levels under our partnership agreement. We do not anticipate that we will make any distributions from capital surplus.
Incentive Distribution Rights


Incentive distribution rights represent the right to receive an increasing percentage of quarterly distributions of Available Cash from operating surplus (as defined in our partnership agreement) after the minimum quarterly distribution to our common unitholders and the target distribution levels have been achieved. Our General Partner currently holds the incentive distribution rights but may transfer these rights separately from its general partner interest, subject to restrictions inwithout unitholder approval. Any transfer by our partnership agreement.

The following table illustratesgeneral partner of the incentive distribution rights would not change the percentage allocations of quarterly distributions with respect to such rights.

Our General Partner is entitled to incentive distributions if the additional Available Cash from operating surplus among theamount we distribute to common unitholders and our General Partner upwith respect to the variousany quarter exceeds specified target distribution levels.levels shown below. The amounts set forth under “Marginal Percentage Interest in Distributions’Interest’’ are the percentage interests of the common unitholders and our General Partner in any Available Cash from operating surplus we distribute up to and including the corresponding amount in the column “Quarterly Distribution Target Amount (per unit),’’ until Available Cash from operating surplus we distribute reaches the next target distribution level, if any. The percentage interests shown for the common unitholders and our General Partner for the minimum quarterly distribution are also applicable to quarterly distribution amounts that are less than the minimum quarterly distribution. The percentage interests shown for our General Partner include its 2.0% general partner interest and assume the General Partner has contributed any capital necessary to maintain its 2.0% general partner interest and has not transferred the incentive distribution rights.

Exchange Controls and Other Limitations Affecting Unitholders
We are not aware of any governmental laws, decrees or regulations, including foreign exchange controls, in the Republic of the Marshall Islands that restrict the export or import of capital, or that affect the remittance of dividends, interest or other payments to holders of our securities that are non-resident and not citizens.

We are not aware of any limitations on the right of non-resident or foreign owners to hold or vote our securities imposed by the laws of the Republic of the Marshall Islands or our partnership agreement.
Taxation
Marshall Islands Tax Consequences. We and our subsidiaries do not, and we do not expect that we or they will, conduct business, operations, or transactions in the Republic of The Marshall Islands. Consequently, neither we nor our subsidiaries will be subject to income, capital gains, profits or other taxation under current Marshall Islands law, other than taxes, fines, or fees due to (i) the incorporation, dissolution, continued existence, merger, domestication (or similar concepts) of legal entities registered in the Republic of the Marshall Islands (ii) filing certificates (such as certificates of incumbency, merger, or re-domiciliation) with The Marshall Islands registrar, (iii) obtaining certificates of good standing from, or certified copies of documents filed with, The Marshall Islands registrar, or (iv) compliance with Marshall Islands law concerning vessel ownership, such as tonnage tax, or (v) non-compliance with requests made by the Marshall Islands registrar of corporations relating to our books and records and the books and records of our subsidiaries. As a result, distributions by our subsidiaries to us will not be subject to Marshall Islands taxation. In addition, because all documentation related to our initial public offering and follow-on offerings were executed outside of the Republic of The Marshall Islands, under current Marshall Islands law, no taxes or withholdings are imposed by the Republic of The Marshall Islands on distributions, including upon a return of capital, made to unitholders, so long as such persons are not citizens of and do not reside in, maintain offices in, nor engage in business, operations, or transactions in the Republic of The Marshall Islands.

This discussion is based upon provisions of the Internal Revenue Code of 1986, as amended (or the Code), legislative history, applicable U.S. Treasury Regulations (or Treasury Regulations), judicial authority and administrative interpretations, all as in effect on the date of this Annual Report, and which are subject to change, possibly with retroactive effect, or are subject to different interpretations. Changes in these authorities may cause the tax consequences to vary substantially from the consequences described below. Unless the context otherwise requires, references in this section to “we,” “our” or “us” are references to Teekay LNG Partners L.P.

This discussion is limited to unitholders who hold their units as capital assets for tax purposes.

dealers in securities or currencies;
traders in securities that have elected the mark-to-market method of accounting for their securities;
persons whose functional currency is not the U.S. Dollar;
persons holding our units as part of a hedge, straddle, conversion or other “synthetic security” or integrated transaction;

insurance companies;
persons subject to the alternative minimum tax;
persons that actually or under applicable constructive ownership rules own 10% or more of our units (by vote or value); and
entities that are tax-exempt for U.S. federal income tax purposes.

Other types of qualifying income include interest (other than from a financial business), dividends, gains from the sale of real property and gains from the sale or other disposition of capital assets held for the production of qualifying income, including stock. We have received a ruling from the IRS that we requested in connection with our initial public offering that the income we derive from transporting LNG and crude oil pursuant to time charters existing at the time of our initial public offering is qualifying income within the meaning of Section 7704. Furthermore, final Treasury Regulations issued early last year specifically provide that income derived from the transportation of LNG, crude oil and products derived therefrom pursuant to time charters is qualifying income. However, in furtherance of Executive Orders issued by the current administration, the U.S. Treasury Department has initiated a comprehensive review of all tax regulations. Should the final regulations be withdrawn or otherwise deemed inapplicable, we would need to continue to rely on the ruling that we received from the IRS. A ruling from the IRS, while generally binding on the IRS, may under certain circumstances be revoked or modified by the IRS retroactively.

We estimate that less than 5%extent of our current income is not qualifying income and therefore we believe that we will be treatedaccumulated earnings and profits allocated to the U.S. Holder’s units, as a partnership fordetermined under U.S. federal income tax purposes. However, this estimate could change from time to time for various reasons. Because we have not received an IRS ruling or an opinionprinciples. Distributions in excess of counsel that any (1) income we derive from transporting crude oil, natural gasour current and products thereof, including LNG, pursuant to bareboat charters or (2) income or gain we recognize from foreign currency transactions, is qualifying income, we currently are not treating income from those sources as qualifying income. Under some circumstances, suchaccumulated earnings and profits will be treated first as a significant changenontaxable return of capital to the extent of the U.S. Holder’s tax basis in foreign currency rates,our units and thereafter as capital gain, which will be either long-term or short-term capital gain depending upon whether the percentage of income or gain from foreign currency transactions in relation to our total gross income could be substantial. We do not expect income or gains from these sources and other income or gainsU.S. Holder has held the units for more than one year. U.S. Holders that are not qualifying income to constitute 10% or more of our gross income for U.S. federal income tax purposes. However, it is possible that the operation of certain of our vessels pursuant to bareboat charters could, in the future, cause our non-qualifying income to constitute 10% or more of our future gross income if such vessels were held in a pass-through structure. In order to preserve our status as a partnershipcorporations for U.S. federal income tax purposes we havegenerally will not be entitled to claim a dividends received a ruling from the IRS that effectively allows us to conduct our bareboat charter operations in a subsidiary corporation.
Status as a Partner
The treatment of unitholders described in this section applies only to unitholders treated as partners in us for U.S. federal income tax purposes. Common unitholders who have been properly admitted as limited partners of Teekay LNG Partners L.P. will be treated as partners in us for U.S. federal income tax purposes. In addition, although there is no direct controlling authoritydeduction with respect to our preferred units, we will treat preferred unitholders who have been properly admitted as limited partnersany distributions they receive from us. For purposes of Teekay LNG Partners L.P. as partnerscomputing allowable foreign tax credits for U.S. federal income tax purposes, and the discussion in this Annual Report assumes that the preferreddividends received with respect to our units will be treated as partnership interests. Other U.S. tax consequences would result if, contrary to our treatment of the preferred units as partnership interests, our preferred units were toforeign source income and generally will be treated as indebtedness for U.S. federal income tax purposes.“passive category income.”

Assignees of

Subject to holding period requirements and certain other limitations, dividends received with respect to our units who have executed and delivered transfer applications, and are awaiting admission as limited partners and unitholders whose units are held in street name or by a nomineeU.S. Holder who is an individual, trust or estate (or a Non-Corporate U.S. Holder) will be treated as “qualified dividend income” that is taxable to such Non-Corporate U.S. Holder at preferential capital gain tax rates provided that we are not classified as a PFIC for the taxable year during which the dividend is paid or the immediately preceding taxable year (we intend to take the position that we are not now and who have never been classified as a PFIC, as discussed below). Any dividends received with respect to our units not eligible for these preferential rates will be taxed as ordinary income to a Non-Corporate U.S. Holder.

Special rules may apply to any “extraordinary dividend” paid by us. Generally, an extraordinary dividend is a dividend with respect to a share of stock if the rightamount of the dividend is equal to direct the nomineeor in excess of 10% of a common stockholder’s, or 5% of a preferred stockholder’s, adjusted tax basis (or fair market value in certain circumstances) in such stock. In addition, extraordinary dividends include dividends received within a one-year period that, in the exerciseaggregate, equal or exceed 20% of all substantive rights attendant toa stockholder’s adjusted tax basis (or fair market value in certain circumstances). If we pay an “extraordinary dividend” on our units that is treated as “qualified dividend income,” then any loss recognized by a Non-Corporate U.S. Holder from the ownershipsale or exchange of theirsuch units will be treated as partners in us for U.S. federal income tax purposes.long-term capital loss to the extent of the amount of such dividend.

The status of assignees of units whoCertain Non-Corporate U.S. Holders are entitledsubject to execute and deliver transfer applications and thereby become entitled to direct the exercise of attendant rights, but who fail to execute and deliver transfer applications, is unclear. In addition, a purchaser or other transferee of units who does not execute and deliver a transfer application may not receive some U.S. federal income tax information or reports furnished to record holders of units, unless the units are held in a nominee or street name account and the nominee or broker has executed and delivered a transfer application for those units.

Under certain circumstances, a beneficial owner of units whose units have been loaned to another may lose its status as a partner with respect to those units for U.S. federal income tax purposes.

In general, a person who is not a partner in a partnership for U.S. federal income tax purposes is not required or permitted to report any share of the partnership’s income, gain, deductions or losses for such purposes, and any cash distributions received by such a person from the partnership therefore may be fully taxable as ordinary income. Unitholders are urged to consult their tax advisors with respect to their status as partners in us for U.S. federal income tax purposes.
Consequences of Unit Ownership
Flow-through of Taxable Income. Each unitholder is required to include in computing its taxable income its allocable share of our items of income, gain, loss, deduction and credit for our taxable year ending with or within its taxable year, without regard to whether we make corresponding cash distributions to it. Our taxable year ends on December 31. Consequently, we may allocate income to a unitholder as of December 31 of a given year, and the unitholder will be required to report this income on its tax return for its tax year that ends on or includes such date, even if it has not received a cash distribution from us as of that date. As discussed further below under “—Allocation of Income,


Gain, Loss, Deduction and Credit,” we do not expect to allocate any income, gain, loss, deduction or credit in respect of our preferred units except in limited circumstances.

In addition, certain U.S. unitholders who are individuals, estates or trusts currently are required to pay an additional 3.8% tax on among other things, thecertain investment income, allocated to them. Unitholdersincluding dividends. Non-Corporate U.S. Holders should consult their tax advisors regarding the effect, if any, of this tax on their ownership of our units.

TreatmentSale, Exchange or Other Disposition of Distributions. Except as describedUnits

Subject to the discussion of PFICs below, with respect to distributions in respect of preferred units, distributions by us to a unitholderU.S. Holder generally will not be taxablerecognize capital gain or loss upon a sale, exchange or other disposition of our units in an amount equal to the unitholderdifference between the amount realized by the U.S. Holder from such sale, exchange or other disposition and the U.S. Holder’s tax basis in such units. Subject to the discussion of extraordinary dividends above, such gain or loss generally will be treated as (a) long-term capital gain or loss if the U.S. Holder’s holding period is greater than one year at the time of the sale, exchange or other disposition, or short term capital gain or loss otherwise and (b) U.S. source gain or loss, as applicable, for foreign tax credit purposes. Non-Corporate U.S. Holders may be eligible for preferential rates of U.S. federal income tax purposesin respect of long-term capital gains. A U.S. Holder’s ability to the extent of itsdeduct capital losses is subject to certain limitations.

Certain Non-Corporate U.S. Holders are subject to a 3.8% tax basis in its common units immediately before the distribution. Our cash distributions in excess of a unitholder’s tax basis generally will be considered to be gainon certain investment income, including capital gains from the sale or exchangeother disposition of common units, taxable in accordance with the rules described under “-Disposition of Common Units” below. Any reduction in a unitholder’s share of our liabilities for which no partner, including the general partner, bears the economic risk of loss, known as “nonrecourse liabilities,” will be treated as a distribution of cash to that unitholder. A decrease in a unitholder’s percentage interest in us because of our issuance of additional common units will decrease its share of our nonrecourse liabilities, and thus will result in a corresponding deemed distribution of cash. To the extent our distributions cause a unitholder’s “at risk” amount to be less than zero at the end of any taxable year, it must recapture any losses deducted in previous years.

A non-pro rata distribution of money or property may result in ordinary income to a unitholder, regardless of its tax basis in its common units, if the distribution reduces the unitholder’s share of our “unrealized receivables,” including depreciation recapture, and/or substantially appreciated “inventory items,” both as defined in the Code (or, collectively, Section 751 Assets). To that extent, a unitholder will be treated as having been distributed its proportionate share of the Section 751 Assets and having exchanged those assets with us in return for the non-pro rata portion of the actual distribution made to him. This latter deemed exchange will generally result in the unitholder’s realization of ordinary income, which will equal the excess of (1) the non-pro rata portion of that distribution over (2) the unitholder’s tax basis for the share of Section 751 Assets deemed relinquished in the exchange.

We will treat distributions on our preferred units (including the distribution of any accumulated and previously unpaid distributions upon our liquidation) as guaranteed payments for the use of capital that generally will be taxable to preferred unitholders as ordinary income and will be deductible by us. Distributions on the preferred units will accrue and be paid quarterly to preferred unitholders who hold their preferred units on the last day of each calendar quarter. However, it is not entirely certain that this treatment would be respected by the IRS. Consequently, it is possible that a preferred unitholder could recognize taxable income from the accrual of a guaranteed payment even in the absence of a contemporaneous distribution. Preferred unitholders should consult their tax advisors as to the amount and timing of taxable income with respect to their preferred units.

Certain Non-Corporate U.S. preferred unitholders who are individuals, estates or trusts currently are required to pay an additional 3.8% tax on, among other things, guaranteed payments for the use of capital. Preferred unitholdersHolders should consult their tax advisors regarding the effect, if any, of this tax on their ownership of our Preferred units.

Tax Basis of Units. A unitholder’s initial U.S. federal income tax basis for its units will be the amount it paid for the units plus its share of our nonrecourse liabilities. That tax basis will be increased by its share of our income and by any increases in its share of our nonrecourse liabilities and by its share of our tax-exempt income, if any, and decreased, but not below zero, by distributions from us, by the unitholder’s share of our losses, by any decreases in its share of our nonrecourse liabilities and by its share of our expenditures that are not deductible in computing taxable income and are not required to be capitalized. A unitholder will have no share of our debt that is recourse to the general partner, but will have a share, generally based on its share of profits, of our nonrecourse liabilities.

A preferred unitholder will not be allocated any of our nonrecourse liabilities and distributions made by us, to the extent treated as guaranteed payments, will not affect a preferred unitholder’s tax basis. Accordingly, except in certain limited situations, as discussed below under “-Allocation of Income, Gain, Loss, Deduction and Credit,” a preferred unitholder’s tax basis with respect to preferred units is not expected to change. The IRS has ruled that a partner who acquires interests in a partnership in separate transactions must combine those interests and maintain a single adjusted tax basis for all of those interests. Preferred unitholders who also own common units should consult their tax advisors with respect to determining the tax basis in their units.

Limitations on Deductibility of Losses. The deduction by a unitholder of its share of our losses will be limited to the tax basis in its units and, in the case of an individual unitholder or a corporate unitholder more than 50% of the value of the stock of which is owned directly or indirectly by five or fewer individuals or some tax-exempt organizations (or a Closely Held Corporation), to the amount for which the unitholder is considered to be “at risk” with respect to our activities, if that is less than its tax basis. In general, a unitholder will be at risk to the extent of the tax basis of its units, excluding any portion of that basis attributable to its share of our nonrecourse liabilities, reduced by any amount of money it borrows to acquire or hold its units, if the lender of those borrowed funds owns an interest in us, is related to the unitholder or can look only to the units for repayment. A unitholder must recapture losses deducted in previous years to the extent that distributions cause its at risk amount to be less than zero at the end of any taxable year. Losses disallowed to a unitholder or recaptured as a result of these limitations will carry forward and will be allowable to the extent that its tax basis or at risk amount, whichever is the limiting factor, is subsequently increased. Upon the taxable disposition of a unit, any gain recognized by a unitholder can be offset by losses that were previously suspended by the at risk limitation but may not be offset by losses suspended by the basis limitation. Any excess suspended loss above that gain is no longer utilizable.

The passive loss limitations generally provide that individuals, estates, trusts and some Closely-Held Corporations and personal service corporations can deduct losses from a passive activity only to the extent of the taxpayer’s income from the same passive activity. Passive activities generally are corporate or partnership activities in which the taxpayer does not materially participate. The passive loss limitations


are applied separately with respect to each publicly traded partnership. Consequently, any passive losses we generate only will be available to offset our passive income generated in the future and will not be available to offset income from other passive activities or investments, including our investments or investments in other publicly traded partnerships, or salary or active business income. Passive losses that are not deductible because they exceed a unitholder’s share of income we generate may be deducted in full when it disposes of its entire investment in us in a fully taxable transaction with an unrelated party. The passive activity loss rules are applied after other applicable limitations on deductions, including the at risk rules and the basis limitation.

In addition to the limitations described above, non-corporate taxpayers may only deduct business losses up to the gross income or gain attributable to such trade or business plus $250,000 ($500,000 for unitholders filing jointly). Amounts that may not be deducted in a taxable year may be carried forward into the following taxable year. This limitation shall be applied after the passive loss limitations and, unless amended, applies only to taxable years beginning prior to December 31, 2025.

Dual consolidated loss restrictions also may apply to limit the deductibility by a corporate unitholder of losses we incur. Corporate unitholders are urged to consult their own tax advisors regarding the applicability and effect to them of dual consolidated loss restrictions.

Limitations on Interest Deductions.

Our ability to deduct interest on our indebtedness allocable to our trade or business will be limited to an amount equal to the sum of (i) our (or our applicable subsidiaries’) business interest income during the taxable year and (ii) 30% of our (or our applicable subsidiaries’) adjusted taxable income for such taxable year. If we (or our subsidiaries) are not entitled to fully deduct business interest in any taxable year, such excess interest expense will be allocated to each unitholder as excess business interest and can be carried forward by the unitholder to successive taxable years and used to offset any excess taxable income allocated by us to such unitholder in future taxable years. Any excess business interest expense allocated to a unitholder will reduce such unitholder’s tax basis in our units in the year of the allocation even if the expense does not give rise to a deduction to the unitholder in that year.

The deductibility of a non-corporate taxpayer’s “investment interest expense” generally is limited to the amount of that taxpayer’s “net investment income.” For this purpose, investment interest expense includes, among other things, a unitholder’s share of our interest expense attributed to portfolio income. The IRS has indicated that net passive income earned by a publicly traded partnership will be treated as investment income to its unitholders. In addition, the unitholder’s share of our portfolio income will be treated as investment income.

Entity-Level Collections. If we are required or elect under applicable law to pay any U.S. federal, state or local or foreign income or withholding taxes on behalf of any present or former unitholder or the general partner, we are authorized to pay those taxes from our funds. That payment, if made, will be treated as a distribution of cash to the partner on whose behalf the payment was made. We are authorized to amend the partnership agreement in the manner necessary to maintain uniformity of intrinsic tax characteristics of units and to adjust later distributions, so that after giving effect to these distributions, the priority and characterization of distributions otherwise applicable under the partnership agreement are maintained as nearly as is practicable. Payments by us as described above could give rise to an overpayment of tax on behalf of an individual partner, in which event the partner would be required to file a claim in order to obtain a credit or refund of tax paid.

Allocation of Income, Gain, Loss, Deduction and Credit. In general, if we have a net profit, our items of income, gain, loss, deduction and credit will be allocated among the general partner and the common unitholders in accordance with their percentage interests in us. At any time that incentive distributions are made to the general partner, gross income will be allocated to the general partner to the extent of these distributions. If we have a net loss for the entire year, that loss generally will be allocated first to the general partner and the common unitholders in accordance with their percentage interests in us to the extent of their positive capital accounts and, second, to the general partner.

Preferred unitholders will be allocated loss to the extent of their positive capital accounts only after the capital accounts of the general partner and the common unitholders have been reduced to zero. In general, the capital account with respect to a preferred unit will be equal to the liquidation preference of the preferred unit, or $25.00, without regard to the price paid for such units, but will have an initial tax basis with respect to the preferred unit equal to the price paid for such unit. To the extent the purchase price paid for a preferred unit exceeds the liquidation preference of such unit, we will have income that will be allocated to our general partner and the holders of units other the preferred units in accordance with their percentage interest. In the event that a preferred unitholder is allocated net loss with respect to a taxable year, such preferred unitholder will be allocated items of income and gain in the earliest succeeding taxable year or years in which there are items of income and gain to the extent necessary to restore its capital account with respect to each preferred unit to equal the liquidation preference. Except as specifically provided in this paragraph, we do not expect to allocate any income or loss in respect of our preferred units.

Specified items of our income, gain, loss and deduction will be allocated to account for any difference between the tax basis and fair market value of any property held by the partnership immediately prior to an offering of units, referred to in this discussion as “Adjusted Property.” The effect of these allocations to a unitholder purchasing units in an offering essentially will be the same as if the tax basis of our assets were equal to their fair market value at the time of the offering. In addition, items of recapture income will be allocated to the extent possible to the partner who was allocated the deduction giving rise to the treatment of that gain as recapture income in order to minimize the recognition of ordinary income by some unitholders. Finally, although we do not expect that our operations will result in the creation of negative capital accounts, if negative capital accounts nevertheless result, items of our income and gain will be allocated in an amount and manner to eliminate the negative balance as quickly as possible.

An allocation of items of our income, gain, loss, deduction or credit, other than an allocation required by the Code to eliminate the difference between a partner’s “book” capital account, which is credited with the fair market value of Adjusted Property, and “tax” capital account, which is credited with the tax basis of Adjusted Property, referred to in this discussion as the “Book-Tax Disparity,” generally will be given effect for U.S. federal income tax purposes in determining a partner’s share of an item of income, gain, loss, deduction or credit only if the allocation


has substantial economic effect. In any other case, a partner’s share of an item will be determined on the basis of its interest in us, which will be determined by taking into account all the facts and circumstances, including:

the type of interest held by the partner;
its relative contributions to us;
the interests of all the partners in profits and losses;
the interest of all the partners in cash flow; and
the rights of all the partners to distributions of capital upon liquidation.

A unitholder’s taxable income or loss with respect to a unit each year will depend upon a number of factors, including (1) the nature and fair market value of our assets at the time the holder acquired the unit, (2) whether we issue additional units or we engage in certain other transactions and (3) the manner in which our items of income, gain, loss, deduction and credit are allocated among our partners. For this purpose, we determine the value of our assets and the relative amounts of our items of income, gain, loss, deduction and credit allocable to our unitholders and our General Partner as holder of the incentive distribution rights by reference to the value of our interests, including the incentive distribution rights. The IRS may challenge any valuation determinations that we make, particularly as to the incentive distribution rights, for which there is no public market. Moreover, the IRS could challenge certain other aspects of the manner in which we determine the relative allocations made to our unitholders and to the General Partner as holder of our incentive distribution rights. A successful IRS challenge to our valuation or allocation methods could increase the amount of net taxable income and gain realized by a unitholder with respect to a unit.

Section 754 Election. We have made an election under Section 754 of the Code to adjust a unit purchaser’s U.S. federal income tax basis in our assets (or inside basis) to reflect the purchaser’s purchase price (or a Section 743(b) adjustment). The Section 743(b) adjustment belongs to the purchaser and not to other unitholders and does not apply to unitholders who acquire their units directly from us. For purposes of this discussion, a unitholder’s inside basis in our assets will be considered to have two components: (1) its share of our tax basis in our assets (or common basis) and (2) its Section 743(b) adjustment to that basis.

In general, a purchaser’s common basis is depreciated or amortized according to the existing method utilized by us. A positive Section 743(b) adjustment to that basis generally is depreciated or amortized in the same manner as property of the same type that has been newly placed in service by us. A negative Section 743(b) adjustment to that basis generally is recovered over the remaining useful life of the partnership’s recovery property.

The calculations involved in the Section 743(b) adjustment are complex and will be made on the basis of assumptions as to the value of our assets and in accordance with the Code and applicable Treasury Regulations. We cannot assure you that the determinations we make will not be successfully challenged by the IRS and that the deductions resulting from them will not be reduced or disallowed altogether. Should the IRS require a different basis adjustment to be made, and should, in our judgment, the expense of compliance exceed the benefit of the election, we may seek consent from the IRS to revoke our Section 754 election. If such consent is given, a subsequent purchaser of units may be allocated more income than it would have been allocated had the election not been revoked.

Treatment of Short Sales. A unitholder whose units are loaned to a “short seller” who sells such units may be considered to have disposed of those units. If so, the unitholder would no longer be a partner with respect to those units until the termination of the loan and may recognize gain or loss from the disposition. As a result, any of our income, gain, loss, deduction or credit with respect to the units may not be reportable by the unitholder who loaned them and any cash distributions received by such unitholder with respect to those units may be fully taxable as ordinary income.

Unitholders desiring to assure their status as partners and avoid the risk of gain recognition from a loan to a short seller are urged to ensure that any applicable brokerage account agreements prohibit their brokers from borrowing their units.
Tax Treatment of Operations
Accounting Method and Taxable Year. We use the calendar year as our taxable year and the accrual method of accounting for U.S. federal income tax purposes. Each unitholder will be required to include in income its share of our income, gain, loss, deduction and credit (and, for preferred unitholders, its income from our guaranteed payments) for our taxable year ending within or with its taxable year. In addition, a unitholder who disposes of all of its units must include its share of our income, gain, loss, deduction and credit through the date of disposition in income for its taxable year that includes the date of disposition, with the result that a unitholder who has a taxable year ending on a date other than December 31 and who disposes of all of its units following the close of our taxable year but before the close of its taxable year must include its share of more than one year of our income, gain, loss, deduction and credit in income for the year of the disposition. Similarly, a preferred unitholder that has a taxable year ending on a date other than December 31 and that disposes of all its units following the close of our taxable year but before the close of its taxable year will be required to include in income for its taxable year income from more than one year of guaranteed payments.

Asset Tax Basis, Depreciation and Amortization. The tax basis of our assets will be used for purposes of computing depreciation and cost recovery deductions and, ultimately, gain or loss on the disposition of these assets. The U.S. federal income tax burden associated with any difference between the fair market value of our assets and their tax basis immediately prior to an offering of units will be borne by the general partner and the existing limited partners.



To the extent allowable, we may elect to use the depreciation and cost recovery methods that will result in the largest deductions being taken in the earliest years after assets are placed in service. Property we subsequently acquire or construct may be depreciated using any method permitted by the Code.

If we dispose of depreciable property by sale, foreclosure or otherwise, all or a portion of any gain, determined by reference to the amount of depreciation previously deducted and the nature of the property, may be subject to the recapture rules and taxed as ordinary income rather than capital gain. Similarly, a unitholder who has taken cost recovery or depreciation deductions with respect to property we own likely will be required to recapture some or all of those deductions as ordinary income upon a sale of its interest in us.

The U.S. federal income tax consequences of the ownership and disposition of units will depend in part on our estimates of the relative fair market values, and the tax bases, of our assets at the time (a) the unitholder acquired its unit, (b) we issue additional units or (c) we engage in certain other transactions. Although we may from time to time consult with professional appraisers regarding valuation matters, we will make many of the relative fair market value estimates ourselves. These estimates and determinations of basis are subject to challenge and will not be binding on the IRS or the courts. If the estimates of fair market value or basis are later found to be incorrect, the character and amount of items of income, gain, loss, deductions or credits previously reported by unitholders might change, and unitholders might be required to adjust their tax liability for prior years and incur interest and penalties with respect to those adjustments.
Disposition of Units
Recognition of Gain or Loss. In general, gain or loss will be recognized on a sale of units equal to the difference between the amount realized and the unitholder’s tax basis in the units sold. A unitholder’s amount realized will be measured by the sum of the cash, the fair market value of other property received by it and, in the case of a common unitholder, its share of our nonrecourse liabilities. Because the amount realized by a common unitholder includes a common unitholder’s share of our nonrecourse liabilities, the gain recognized on the sale of units could result in a tax liability in excess of any cash or property received from the sale.

Prior distributions from us in excess of cumulative net taxable income for a common unit that decreased a common unitholder’s tax basis in that common unit will, in effect, become taxable income if the common unit is sold at a price greater than the common unitholder’s tax basis in that common unit, even if the price received is less than its original cost. Except as noted below, gain or loss recognized by a unitholder on the sale or exchange of a unit generally will be taxable as capital gain or loss. Capital gain recognized by an individual on the sale of units held more than one year generally will be taxed at preferential tax rates. Capital loss may offset capital gains and, in the case of an individual, up to $3,000 of ordinary income per year.

A portion of a common unitholder’s amount realized may be allocable to “unrealized receivables” or to “inventory items” we own. The term “unrealized receivables” includes potential recapture items, including depreciation and amortization recapture. A common unitholder will recognize ordinary income or loss to the extent of the difference between the portion of the common unitholder’s amount realized allocable to unrealized receivables or inventory items and the common unitholder’s share of our basis in such receivables or inventory items. Ordinary income attributable to unrealized receivables, inventory items and depreciation or amortization recapture may exceed net taxable gain realized upon the sale of a common unit and may be recognized even if a net taxable loss is realized on the sale of a common unit. Thus, a common unitholder may recognize both ordinary income and a capital loss upon a sale of common units. Because preferred unitholders generally are not expected to be allocated a share of our items of depreciation, depletion or amortization, it is not anticipated that preferred unitholders would be required to recharacterize any portion of their gain as ordinary income as a result of these rules. However, it is uncertain as to whether a portion of their gain may be required to be recharacterized as ordinary income to the extent that it represents the accrued but unpaid portion of the guaranteed payment to be paid on the next distribution date.

The IRS has ruled that a partner who acquires interests in a partnership in separate transactions must combine those interests and maintain a single adjusted tax basis for all those interests. Upon a sale or other disposition of less than all of those interests, a portion of that tax basis must be allocated to the interests sold using an “equitable apportionment” method. Treasury Regulations under Section 1223 of the Code allow a selling unitholder who can identify units transferred with an ascertainable holding period to elect to use the actual holding period of the units transferred. Thus, according to the ruling, a unitholder will be unable to select high or low basis units to sell as would be the case with corporate stock, but, according to the Treasury Regulations, may designate specific units sold for purposes of determining the holding period of units transferred. A unitholder electing to use the actual holding period of units transferred must consistently use that identification method for all subsequent sales or exchanges of units. A unitholder considering the purchase of additional units or a sale of units purchased in separate transactions is urged to consult its tax advisor as to the possible consequences of this ruling and application of the Treasury Regulations.

In addition, certain U.S. unitholders who are individuals, estates or trusts are required to pay an additional 3.8% tax on, among other things, capital gain from the sale or other disposition of their units. Unitholders should consult their tax advisors regarding the effect, if any, of this tax on their ownership of our units.

Allocations Between Transferors and Transferees. In general, our taxable income or loss will be determined annually, will be prorated on a monthly basis and will be subsequently apportioned among the common unitholders in proportion to the number of common units owned by each of them as of the opening of the applicable exchange on the first business day of the month. However, gain or loss realized on a sale or other disposition of our assets other than in the ordinary course of business will be allocated among the common unitholders on the first business day of the month in which that gain or loss is recognized. As a result of the foregoing, a common unitholder transferring common units may be allocated income, gain, loss, deduction and credit realized after the date of transfer. A common unitholder who owns common units at any time during a calendar quarter and who disposes of them prior to the record date set for a cash distribution for that quarter will


be allocated items of our income, gain, loss, deductions and credit attributable to months within that quarter in which the common units were held but will not be entitled to receive that cash distribution. Treasury Regulations allow a similar monthly simplifying convention. However, such regulations do not specifically authorize all aspects of the proration method we have adopted. If the IRS were to challenge our proration method, we may be required to change the allocation of items of income, gain, loss and deduction among our common unitholders. Because preferred unitholders generally are not expected to be allocated a share of our items of depreciation, depletion or amortization, it is not anticipated that preferred unitholders would be affected by the proration method we have adopted.

Holders of preferred units owning preferred units as of the close of the applicable exchange on the last business day of a calendar quarter (or the Allocation Date) will be entitled to receive the distribution of the guaranteed payment payable with respect to their preferred units for that quarter on the next distribution payment date. Purchasers of preferred units after the Allocation Date will therefore not be entitled to a cash distribution on their preferred units until the next Allocation Date.

Transfer Notification Requirements. A unitholder who sells any of its units, other than through a broker, generally is required to notify us in writing of that sale within 30 days after the sale (or, if earlier, January 15 of the year following the sale). A unitholder who acquires units generally is required to notify us in writing of that acquisition within 30 days after the purchase, unless a broker or nominee will satisfy such requirement. We are required to notify the IRS of any such transfers of units and to furnish specified information to the transferor and transferee. Failure to notify us of a transfer of units may lead to the imposition of substantial penalties.
Foreign Tax Credit Considerations
Subject to detailed limitations set forth in the Code, a unitholder may elect to claim a credit against its liability for U.S. federal income tax for its share of foreign income taxes (and certain foreign taxes imposed in lieu of a tax based upon income) paid by us. Income allocated to unitholders generally will constitute foreign source income for purposes of the U.S. foreign tax credit limitation. The rules relating to the determination of the foreign tax credit are complex and unitholders are urged to consult their tax advisors to determine whether or to what extent they would be entitled to such credit. A unitholder who does not elect to claim foreign tax credits may instead claim a deduction for its share of foreign taxes paid by us.
Tax-Exempt Organizations and Non-U.S. Investors
Investments in units by employee benefit plans, other tax-exempt organizations and non-U.S. persons, including nonresident aliens of the United States, non-U.S. corporations and non-U.S. trusts and estates (collectively, non-U.S. unitholders) raise issues unique to those investors and, as described below, may result in substantially adverse tax consequences to them.

Employee benefit plans and most other organizations exempt from U.S. federal income tax, including individual retirement accounts and other retirement plans, are subject to U.S. federal income tax on unrelated business taxable income (or UBTI). Virtually all of our income allocated to a unitholder that is such a tax-exempt organization will be UBTI to it subject to U.S. federal income tax. As described above, we will treat distributions on the preferred units as guaranteed payments for the use of capital. The treatment of guaranteed payments for the use of capital to tax-exempt investors is not certain because there is no direct controlling authority on such treatment. Accordingly, such guaranteed payments may be treated as UBTI. Preferred unitholders that are tax-exempt organizations are encouraged to consult with their tax advisors regarding the tax consequences to them of the receipt of guaranteed payments for the use of capital.

A non-U.S. unitholder may be subject to a 4% U.S. federal income tax on its share of the U.S. source portion of our gross income attributable to transportation that begins or ends (but not both) in the United States, unless either (a) an exemption applies and it files a U.S. federal income tax return to claim that exemption or (b) that income is effectively connected with the conduct of a trade or business in the United States (or U.S. effectively connected income). The applicability of this tax to the guaranteed payments made to preferred unitholders is uncertain. However, we believe that preferred unitholders would be treated as receiving an allocable share of the U.S. source portion of our transportation income and, therefore, may be subject to this tax. For this purpose, transportation income includes income from the use, hiring or leasing of a vessel to transport cargo, or the performance of services directly related to the use of any vessel to transport cargo. The U.S. source portion of our transportation income is deemed to be 50% of the income attributable to voyages that begin or end (but not both) in the United States. Generally, no amount of the income from voyages that begin and end outside the United States is treated as U.S. source, and consequently a non-U.S. unitholder would not be subject to U.S. federal income tax with respect to our transportation income attributable to such voyages. Although the entire amount of transportation income from voyages that begin and end in the United States would be fully taxable in the United States, we currently do not expect to have a material amount of transportation income from voyages that begin and end in the United States.

A non-U.S. unitholder may be entitled to an exemption from the 4% U.S. federal income tax or a refund of tax withheld on U.S. effectively connected income that constitutes transportation income if any of the following applies: (1) such non-U.S. unitholder qualifies for an exemption from this tax under an income tax treaty between the United States and the country where such non-U.S. unitholder is resident; (2) in the case of an individual non-U.S. unitholder, it qualifies for the exemption from tax under Section 872(b)(1) of the Code as a resident of a country that grants an equivalent exemption from tax to residents of the United States; or (3) in the case of a corporate non-U.S. unitholder, it qualifies for the exemption from tax under Section 883 of the Code (or the Section 883 Exemption) (for the rules relating to qualification for the Section 883 Exemption, please read below under “— Possible Classification as a Corporation — The Section 883 Exemption”).

We may be required to withhold U.S. federal income tax, computed at the highest statutory rate, from cash distributions to non-U.S. unitholders with respect to their shares of our income that is U.S. effectively connected income. Our transportation income generally should not be treated as U.S. effectively connected income unless we have a fixed place of business in the United States and substantially all of such transportation


income is attributable to either regularly scheduled transportation or, in the case of income derived from bareboat charters, is attributable to the fixed place of business in the United States. While we do not expect to have any regularly scheduled transportation or a fixed place of business in the United States, there can be no guarantee that this will not change. If we were to earn any U.S. effectively connected income, we believe a non-U.S. unitholder (including a non-U.S. preferred unitholder) would be treated as being engaged in such business and would be required to file a U.S. federal income tax return to report its U.S. effectively connected income (including its share of any such income earned by us) and to pay U.S. federal income tax, or claim a credit or refund for tax withheld on such income. Further, unless an exemption applies, a non-U.S. corporation investing in units may be subject to a branch profits tax, at a 30% rate or lower rate prescribed by a treaty, with respect to its U.S. effectively connected income. A portion of any gain recognized on the sale or other disposition of a unit by a non-U.S. unitholder may be treated as U.S. effectively connected income to the extent of the portion of a unitholder’s distributive share which would have given rise to U.S. effectively connected income if we had sold all of our assets at their fair market value as of the date of the sale or disposition. In addition, the transferee of an interest in a partnership that is engaged in a U.S. trade or business is generally required to withhold 10% of the amount realized by the transferor unless the transferor certifies that it is not a foreign person, and we are required to deduct and withhold from the transferee amounts that should have been withheld by the transferees but were not withheld. However, the IRS has suspended the application of this withholding rule to open market transfers of interest in publicly traded partnerships until further guidance is provided, pending promulgation of regulations that address the amount to be withheld, the reporting necessary to determine such amount and the appropriate party to withhold such amounts, but it is not clear if or when such regulations will be issued.

Non-U.S. unitholders must apply for and obtain a U.S. taxpayer identification number in order to file U.S. federal income tax returns and must provide that identification number to us for purposes of any U.S. federal income tax information returns we may be required to file. Non-U.S. unitholders are encouraged to consult their tax advisors regarding the U.S. federal, state, local and other tax consequences of an investment in units and any filing requirements related thereto.
Functional Currency
We are required to determine the functional currency of any of our operations that constitute a separate qualified business unit (or QBU) for U.S. federal income tax purposes. For purposes of the foreign currency rules, a QBU includes a separate trade or business owned by a partnership in the event separate books and records are maintained for that separate trade or business. The functional currency of a QBU is determined based upon the economic environment in which the QBU operates. Thus, a QBU whose revenues and expenses are primarily determined in a currency other than the U.S. Dollar will have a non-U.S. Dollar functional currency. We believe our principal operations constitute a QBU whose functional currency is the U.S. Dollar, but certain of our operations constitute separate QBUs whose functional currencies are other than the U.S. Dollar. Any transactions conducted by us other than in the U.S. Dollar or by a QBU other than in its functional currency may give rise to foreign currency exchange gain or loss. The U.S. Treasury Department and the IRS have issued regulations relating to the amount of foreign currency translation gain or loss. However, these regulations do not address the application of the foreign currency translation gain and loss rules to partnerships such as us, and the preamble to these regulations indicates that further regulations will be developed under a separate project. As a result, the manner in which foreign currency translation gain or loss may be recognized by unitholders is uncertain. Despite this uncertainty, based upon our current projections of the capital invested in and profits of the non-U.S. Dollar QBUs and the different ways in which foreign currency translation gain or loss could be recognized, we believe that only a nominal amount of foreign currency translation gain or loss would be recognized each year. Unitholders are urged to consult their tax advisors for specific advice regarding the application of the rules for recognizing foreign currency translation gain or loss.
Information Returns and Audit Procedures
We intend to furnish to each unitholder, within 90 days after the close of each calendar year, specific U.S. federal income tax information, including a document in the form of IRS Form 1065, Schedule K-1, which sets forth its share of our items of income, gain, loss, deductions and credits as computed for U.S. federal income tax purposes and, with respect to a preferred unitholder, the amount of the preferred unitholder’s guaranteed payments, for our preceding taxable year. In preparing this information, which will not be reviewed by counsel, we will take various accounting and reporting positions, some of which have been mentioned earlier, to determine each unitholder’s share of such items of income, gain, loss, deduction and credit. We cannot assure you that those positions will yield a result that conforms to the requirements of the Code, Treasury Regulations or administrative interpretations of the IRS. We cannot assure unitholders that the IRS will not successfully contend that those positions are impermissible. Any challenge by the IRS could negatively affect the value of the units.

We will be obligated to file U.S. federal income tax information returns with the IRS for any year in which we earn any U.S. source income or U.S. effectively connected income. In the event we were obligated to file a U.S. federal income tax information return but failed to do so, unitholders would not be entitled to claim any deductions, losses or credits for U.S. federal income tax purposes relating to us. Consequently, we may file U.S. federal income tax information returns for any given year. The IRS may audit any such information returns that we file. Adjustments resulting from an IRS audit of our return may require each unitholder to adjust a prior year’s tax liability, and may result in an audit of its return. Any audit of a unitholder’s return could result in adjustments not related to our returns as well as those related to our returns. Any IRS audit relating to our items of income, gain, loss, deduction or credit for years in which we are not required to file and do not file a U.S. federal income tax information return would be conducted at the partner-level, and each unitholder may be subject to separate audit proceedings relating to such items.

For years in which we file or are required to file U.S. federal income tax information returns, we will be treated as a separate entity for purposes of any U.S. federal income tax audits, as well as for purposes of judicial review of administrative adjustments by the IRS and tax settlement proceedings. For taxable years beginning prior to January 1, 2018, the tax treatment of partnership items of income, gain, loss, deduction and credit will be determined in a partnership proceeding rather than in separate proceedings with the partners. The Code requires that one


partner be designated as the “Tax Matters Partner” for these purposes. The partnership agreement names Teekay GP L.L.C. as our Tax Matters Partner.

The Tax Matters Partner will make some U.S. federal tax elections on our behalf and on behalf of unitholders. In addition, the Tax Matters Partner can extend the statute of limitations for assessment of tax deficiencies against unitholders for items reported in the information returns we file. The Tax Matters Partner may bind a unitholder with less than a 1% profits interest in us to a settlement with the IRS with respect to these items unless that unitholder elects, by filing a statement with the IRS, not to give that authority to the Tax Matters Partner. The Tax Matters Partner may seek judicial review, by which all the unitholders are bound, of a final partnership administrative adjustment and, if the Tax Matters Partner fails to seek judicial review, judicial review may be sought by any unitholder having at least a 1% interest in profits or by any group of unitholders having in the aggregate at least a 5% interest in profits. However, only one action for judicial review will go forward, and each unitholder with an interest in the outcome may participate.

The procedures for auditing large partnerships and for assessing and collecting taxes due (including applicable penalties and interest) for taxable years beginning after December 31, 2017, have been altered. Unless we are eligible to (and choose to) elect to issue revised schedules K-1 to our partners with respect to an audited and adjusted return, the IRS may assess and collect taxes (including any applicable penalties and interest) directly from us in the year in which the audit is completed under the new rules. If we are required to pay taxes, penalties and interest as the result of audit adjustments, cash available for distribution to our unitholders may be substantially reduced. In addition, because payment would be due for the taxable year in which the audit is completed, unitholders during that taxable year would bear the expense of the adjustment even if they were not unitholders during the audited taxable year. Pursuant to this new legislation, we will designate a person (our General Partner) to act as the partnership representative who shall have the sole authority to act on behalf of the partnership with respect to dealings with the IRS under these new audit procedures.

A unitholder must file a statement with the IRS identifying the treatment of any item on its U.S. federal income tax return that is not consistent with the treatment of the item on an information return that we file. Intentional or negligent disregard of this consistency requirement may subject a unitholder to substantial penalties.
Special Reporting Requirements for Owners of Non-U.S. Partnerships
A U.S. person who either contributes more than $100,000 to us (when added to the value of any other property contributed to us by such person or a related person during the previous 12 months) or following a contribution owns, directly, indirectly or by attribution from certain related persons, at least a 10% interest in us, is required to file IRS Form 8865 with its U.S. federal income tax return for the year of the contribution to report the contribution and provide certain details about himself and certain related persons, us and any persons that own a 10% or greater direct interest in us. We will provide each unitholder with the necessary information about us and those persons who own a 10% or greater direct interest in us along with the Schedule K-1 information described previously.

In addition to the foregoing, a U.S. person who directly owns at least a 10% interest in us may be required to make additional disclosures on IRS Form 8865 in the event such person acquires, disposes or has its interest in us substantially increased or reduced. Further, a U.S. person who directly, indirectly or by attribution from certain related persons, owns at least a 10% interest in us may be required to make additional disclosures on IRS Form 8865 in the event such person, when considered together with any other U.S. persons who own at least a 10% interest in us, owns a greater than 50% interest in us. For these purposes, an “interest” in us generally is defined to include an interest in our capital or profits or an interest in our deductions or losses.

Significant penalties may apply for failing to satisfy IRS Form 8865 filing requirements and thus common unitholders are advised to contact their tax advisors to determine the application of these filing requirements under their own circumstances.

In addition, individual citizens or residents of the United States who hold certain specified foreign financial assets, including units in a foreign partnership not held in an account maintained by a financial institution, with an aggregate value in excess of $50,000, on the last day of a taxable year, or $75,000 at any time during that taxable year, may be required to report such assets on IRS Form 8938 with their U.S. federal income tax return for that taxable year. Penalties apply for failure to properly complete and file IRS Form 8938. Investors are encouraged to consult their tax advisors regarding the potential application of this disclosure requirement.

Accuracy-related Penalties

An additional tax equal to 20% of the amount of any portion of an underpayment of U.S. federal income tax attributable to one or more specified causes, including negligence or disregard of rules or regulations and substantial understatements of income tax, is imposed by the Code. No penalty will be imposed, however, for any portion of an underpayment if it is shown that there was a reasonable cause for that portion and that the taxpayer acted in good faith regarding that portion.

A substantial understatement of income tax in any taxable year exists if the amount of the understatement exceeds the greater of 10% of the tax required to be shown on the return for the taxable year or $5,000. The amount of any understatement subject to penalty generally is reduced if any portion is attributable to a position adopted on the return:

(1)for which there is, or was, “substantial authority”; or
(2)as to which there is a reasonable basis and the pertinent facts of that position are disclosed on the return.



More stringent rules, including additional penalties and extended statutes of limitations, may apply as a result of our participation in “listed transactions” or “reportable transactions with a significant tax avoidance purpose.” While we do not anticipate participating in such transactions, if any item of income, gain, loss, deduction or credit included in the distributive shares of unitholders for a given year might result in an “understatement” of income relating to such a transaction, we will disclose the pertinent facts on a U.S. federal income tax information return for such year. In such event, we also will make a reasonable effort to furnish sufficient information for unitholders to make adequate disclosure on their returns and to take other actions as may be appropriate to permit unitholders to avoid liability for penalties.
Possible Classification as a Corporation
If we fail to meet the Qualifying Income Exception described above with respect to our classification as a partnership for U.S. federal income tax purposes, other than a failure that is determined by the IRS to be inadvertent and that is cured within a reasonable time after discovery, we will be treated as a non-U.S. corporation for U.S. federal income tax purposes. If previously treated as a partnership, our change in status would be deemed to have been effected by our transfer of all of our assets, subject to liabilities, to a newly formed non-U.S. corporation, in return for stock in that corporation, and then our distribution of that stock to our unitholders and other owners in liquidation of their interests in us. Unitholders that are U.S. persons would be required to file IRS Form 926 to report these deemed transfers and any other transfers they made to us while we were treated as a corporation and would be required to recognize gain, if any, for U.S. federal income tax purposes. Substantial penalties may apply for failure to satisfy these reporting requirements, unless the person otherwise required to report shows such failure was due to reasonable cause and not willful neglect.

If we were treated as a corporation in any taxable year, either as a result of a failure to meet the Qualifying Income Exception or otherwise, our items of income, gain, loss, deduction and credit would not pass through to unitholders. Instead, we would be subject to U.S. federal income tax based on the rules applicable to foreign corporations, not partnerships, and such items would be treated as our own. In addition, Section 743(b) adjustments to the basis of our assets would no longer be available to purchasers in the marketplace. Subject to the discussion of passive foreign investment companies (or PFICs) below, any distribution made to a unitholder would be treated as taxable dividend income to the extent of our current and accumulated earnings and profits, as determined under U.S. federal income tax principles. Distributions in excess of our earnings and profits would be treated first as a nontaxable return of capital to the extent of the unitholder’s tax basis in its units, and taxable capital gain thereafter. Dividends paid on our units to U.S. unitholders who are individuals, estates or trusts generally would be treated as “qualified dividend income” that is subject to tax at preferential capital gain rates, subject to certain holding period and other requirements. In addition, certain U.S. unitholders who are individuals, estates or trusts would be required to pay an additional 3.8% tax on the dividends and distributions taxable as capital gain paid to them.

Taxation of Operating Income. We expect that substantially all of our gross income and the gross income of our corporate subsidiaries will be attributable to the transportation of LNG, LPG, ammonia, crude oil and related products. For this purpose, gross income attributable to transportation (or Transportation Income) includes income derived from, or in connection with, the use (or hiring or leasing for use) of a vessel to transport cargo, or the performance of services directly related to the use of any vessel to transport cargo, and thus includes both time charter and bareboat charter income.

Fifty percent (50%) of Transportation Income that either begins or ends, but that does not both begin and end, in the United States (or U.S. Source International Transportation Income) is considered to be derived from sources within the United States. Transportation Income that both begins and ends in the United States (or U.S. Source Domestic Transportation Income) is considered to be 100% derived from sources within the United States. Transportation Income exclusively between non-U.S. destinations is considered to be 100% derived from sources outside the United States. Transportation Income derived from sources outside the United States generally is not subject to U.S. federal income tax.

Based on our current operations and the operations of our subsidiaries, we expect substantially all of our Transportation Income to be from sources outside the United States and not subject to U.S. federal income tax. In addition, we believe that we have not earned a material amount of U.S. Source Domestic Transportation Income, and we expect that we will not earn a material amount of such income in future years. However, in the event we were treated as a corporation, if we or any of our subsidiaries does earn U.S. Source International Transportation Income or U.S. Source Domestic Transportation Income, our income or our subsidiaries’ income would be subject to U.S. federal income taxation under either the net basis and branch profits taxes or the 4% gross basis tax, each of which is discussed below, unless the exemption from U.S. taxation under Section 883 of the Code (or the Section 883 Exemption) applies.

The Section 883 Exemption. In general, the Section 883 Exemption provides that if a non-U.S. corporation satisfies the requirements of Section 883 of the Code and the Treasury Regulations thereunder, it will not be subject to the net basis and branch profits taxes or the 4% gross basis tax described below on its U.S. Source International Transportation Income. The Section 883 Exemption does not apply to U.S. Source Domestic Transportation Income.

In the event we were treated as a corporation, we do not believe that we would be able to qualify for the Section 883 Exemption and therefore our U.S. Source International Transportation Income would not be exempt from U.S. federal income taxation.

Net Basis Tax and Branch Profits Tax. If we were to be treated as a corporation and if the Section 883 Exemption does not apply, our U.S. Source International Transportation Income may be treated as effectively connected with the conduct of a trade or business in the United States (or Effectively Connected Income) if we have a fixed place of business in the United States and substantially all of our U.S. Source International Transportation Income is attributable to regularly scheduled transportation or, in the case of income derived from bareboat charters, is attributable to a fixed place of business in the United States. Based on our current operations, none of our potential U.S. Source International Transportation Income is attributable to regularly scheduled transportation or is derived from bareboat charters attributable to a fixed place of business in the United States. As a result, if we were classified as a corporation, we do not anticipate that any of our U.S. Source


International Transportation Income would be treated as Effectively Connected Income. However, there is no assurance that we would not earn income pursuant to regularly scheduled transportation or bareboat charters attributable to a fixed place of business in the United States in the future, which would result in such income being treated as Effectively Connected Income if we were classified as a corporation. U.S. Source Domestic Transportation Income generally would be treated as Effectively Connected Income. However, we do not anticipate that a material amount of our income has been, or will be, U.S. Source Domestic Transportation Income.

Any income that we earn that is treated as Effectively Connected Income would be subject to U.S. federal corporate income tax (the highest statutory rate for 2018 onwards is 21%) and a 30% branch profits tax imposed under Section 884 of the Code. In addition, a branch interest tax could be imposed on certain interest paid or deemed paid by us if we were classified as a corporation.

On the sale of a vessel that has produced Effectively Connected Income, we generally would be subject to the net basis and branch profits taxes with respect to our gain recognized up to the amount of certain prior deductions for depreciation that reduced Effectively Connected Income. Otherwise, we would not be subject to U.S. federal income tax with respect to gain realized on sale of a vessel, provided the sale is considered to occur outside of the United States under U.S. federal income tax principles.

The 4% Gross Basis Tax. If we were to be treated as a corporation and if the Section 883 Exemption does not apply and we are not subject to the net basis and branch profits taxes described above, we would be subject to a 4% U.S. federal income tax on our U.S. Source International Transportation Income, without benefit of deductions. We estimate that, in this event, we would be subject to less than $900,000 of U.S. federal income tax in 2018 and in each subsequent year (in addition to any U.S. federal income taxes on our subsidiaries, as described below) based on the amount of U.S. Source International Transportation Income we earned for 2017 and our expected U.S. Source International Transportation Income for 2018 and subsequent years. The amount of such tax for which we would be liable in any year in which we were treated as a corporation for U.S. federal income tax purposes would depend upon the amount of income we earn from voyages into or out of the United States in such year, however, which is not within our complete control.
Consequences of Possible PFIC Classification
A non-U.S. entity treated as a corporation for U.S. federal income tax purposes will be treated as a PFIC in any taxable year in which, after taking into account the income and assets of the corporation and certain subsidiaries pursuant to a “look through” rule, either (i)either: (a) at least 75% of its gross income is “passive” income, or (ii)(b) at least 50% of the average value of its assets is attributable to assets that produce or are held for the production of passive income. For purposes of these tests, “passive income” includes dividends, interest, gains from the sale or exchange of investment property and rents and royalties other(other than rents and royalties that are received from unrelated parties in connection with the active conduct of a trade or business.business). By contrast, income derived from the performance of services does not constitute “passive income.”

There are legal uncertainties involved in determining whether the income derived from our time-chartering activities would constituteconstitutes rental income or income derived from the performance of services, including legal uncertainties arising from the decision in Tidewater Inc. v. United States.States, 565 F.3d 299 (5th Cir. 2009), which held that income derived from certain time-chartering activities should be treated as rental income rather than services income for purposes of a foreign sales corporation provision of the Code. However, the IRS stated in an Action on Decision (AOD 2010-01) that it disagrees with, and will not acquiesce to, the way that the rental versus services framework was applied to the facts in the Tidewater decision, and in its discussion stated that the time charters at issue in Tidewater would be treated as producing services income for PFIC purposes. The IRS’s statement with respect to Tidewater cannot be relied upon or otherwise cited as precedent by taxpayers. Consequently, in the absence of any binding legal authority specifically relating to the statutory provisions governing PFICs, there can be no assurance that the IRS or a court would not follow the Tidewater decision in interpreting the PFIC provisions underof the Code. Moreover, the market value of our units may be treated as reflecting the value of our assets at any given time. Therefore, a decline in the market value of our units, which is not within our control, may impact the determination of whether we are a PFIC. Nevertheless, based on our and our subsidiaries’ current assets and operations, we believeintend to take the position that we wouldare not now be nor wouldand have evernever been a PFIC even if we were treated as a corporation. PFIC.

No assurance can be given, however, that the IRS, wouldor a court of law, will accept thisour position or that we would not constitute a PFIC for any future taxable year if we were treated as a corporation and there were to be changes in our or our subsidiaries’ assets, income or operations.

As discussed more fully below, if we were to be treated as a PFIC for any taxable year, a U.S. Holder generally would be subject to different taxation rules depending on whether the U.S. Holder makes a timely and effective election to treat us as a “Qualified Electing Fund” (or a QEF election). As an alternative to making a QEF election, a U.S. Holder should be able to make a “mark-to-market” election with respect to our units, as discussed below.

Taxation of U.S. Holders Making a Timely QEF Election
A U.S. Holder who makes a timely QEF election (or an Electing Holder) must report the Electing Holder’s pro rata share of our ordinary earnings and net capital gain, if any, for each taxable year for which we are a PFIC that ends with or within the Electing Holder’s taxable year,


regardless of whether or not the Electing Holder received distributions from us in that year. Such income inclusions would not be eligible for the preferential tax rates applicable to qualified dividend income. The Electing Holder’s adjusted tax basis in our units will be increased to reflect taxed but undistributed earnings and profits. Distributions of earnings and profits that were previously taxed will result in a corresponding reduction in the Electing Holder’s adjusted tax basis in our units and will not be taxed again once distributed. An Electing Holder generally will recognize capital gain or loss on the sale, exchange or other disposition of our units. A U.S. Holder makes a QEF election with respect to any year that we are a PFIC by filing IRS Form 8621 with the U.S. Holder’s timely filed U.S. federal income tax return (including extensions).

If a U.S. Holder has not made a timely QEF election with respect to the first year in the U.S. Holder’s holding period of our units during which we qualified as a PFIC, the U.S. Holder may be treated as having made a timely QEF election by filing a QEF election with the U.S. Holder’s timely filed U.S. federal income tax return (including extensions) and, under the rules of Section 1291 of the Code, a “deemed sale election” to include in income as an “excess distribution” (described below) the amount of any gain that the U.S. Holder would otherwise recognize if the U.S. Holder sold the U.S. Holder’s units on the “qualification date.” The qualification date is the first day of our taxable year in which we qualified as a “qualified electing fund” with respect to such U.S. Holder. In addition to the above rules, under very limited circumstances, a U.S. Holder may make a retroactive QEF election if the U.S. Holder failed to file the QEF election documents in a timely manner. If a U.S. Holder makes a timely QEF election for one of our taxable years, but did not make such election with respect to the first year in the U.S. Holder’s holding period of our units during which we qualified as a PFIC and the U.S. Holder did not make the deemed sale election described above, the U.S. Holder also will be subject to the more adverse rules described below.

A U.S. Holder’s QEF election will not be effective unless we annually provide the U.S. Holder with certain information concerning our income and gain, calculated in accordance with the Code, to be included with the U.S. Holder’s U.S. federal income tax return. We do not intend to provide such information in the current taxable year. Accordingly, U.S. Holders will not be able to make an effective QEF election at this time. If, contrary to our expectations, we determine that we are or will be a PFIC for any taxable year, we will provide U.S. Holders with the information necessary to make an effective QEF election with respect to our units.

Taxation of U.S. Holders Making a “Mark-to-Market” Election
If we were to be treated as a PFIC for any taxable year and, as we anticipate, our units were treated as “marketable stock,” then, as an alternative to making a QEF election, a U.S. Holder would be allowed to make a “mark-to-market” election with respect to our units, provided the U.S. Holder completes and files IRS Form 8621 in accordance with the relevant instructions and related Treasury Regulations. If that election is made for the first year a U.S. Holder holds or is deemed to hold our units and for which we are a PFIC, the U.S. Holder generally would include as ordinary income in each taxable year that we are a PFIC the excess, if any, of the fair market value of the U.S. Holder’s units at the end of the taxable year over the U.S. Holder’s adjusted tax basis in the units. The U.S. Holder also would be permitted an ordinary loss in respect of the excess, if any, of the U.S. Holder’s adjusted tax basis in the units over the fair market value thereof at the end of the taxable year that we are a PFIC, but only to the extent of the net amount previously included in income as a result of the mark-to-market election. A U.S. Holder’s tax basis in our units would be adjusted to reflect any such income or loss recognized. Gain recognized on the sale, exchange or other disposition of our units in taxable years that we are a PFIC would be treated as ordinary income, and any loss recognized on the sale, exchange or other disposition of our units in taxable years that we are a PFIC would be treated as ordinary loss to the extent that such loss does not exceed the net mark-to-market gains previously included in income by the U.S. Holder. Because the mark-to-market election only applies to marketable stock, however, it would not apply to a U.S. Holder’s indirect interest in any of our subsidiaries that were also determined to be PFICs.

If a U.S. Holder makes a mark-to-market election for one of our taxable years and we were a PFIC for a prior taxable year during which such U.S. Holder held our units and for which (a) we were not a unitholder ownsQEF with respect to such U.S. Holder and (b) such U.S. Holder did not make a timely mark-to-market election, such U.S. Holder would also be subject to the more adverse rules described below in the first taxable year for which the mark-to-market election is in effect and also to the extent the fair market value of the U.S. Holder’s units exceeds the U.S. Holder’s adjusted tax basis in the units at the end of the first taxable year for which the mark-to-market election is in effect.

Taxation of U.S. Holders Not Making a Timely QEF or Mark-to-Market Election
If we were to be treated as a PFIC for any taxable year, a U.S. unitholder generallyHolder who does not make either a QEF election or a “mark-to-market” election for that year (a Non-Electing Holder ) would be subject to special rules (regardless of whether we continue thereafter to be a PFIC) resulting in increased tax liability with respect to (1)(a) any “excess distribution” (i.e.,(e.g. the portion of any distributions received by a unitholderthe Non- Electing Holder on our common units in a taxable year in excess of 125% of the average annual distributions received by the unitholderNon-Electing Holder in the three preceding taxable years, or, if shorter, the unitholder’sNon-Electing Holder’s holding period for theour units), and (2)(b) any gain realized uponon the sale, exchange or other disposition of our units. Under these special rules:

the excess distribution or gain willwould be allocated ratably over the unitholder’sNon-Electing Holder’s aggregate holding period for the commonour units;
the amount allocated to the current taxable year and any taxable year prior to the taxable year we were first treated as a PFIC with respect to the unitholderNon-Electing Holder would be taxed as ordinary income in the current taxable year;
the amount allocated to each of the other taxable years would be subject to U.S. federal income tax at the highest rate of tax in effect for the applicable class of taxpayer for that year; and
an interest charge for the deemed deferral benefit would be imposed with respect to the resulting tax attributable to each such other taxable year.

In addition,Additionally, for each year during which a U.S. unitholderHolder holds our units, we were treated asare a PFIC, and the total value of all PFIC stockunits that such U.S. unitholderHolder directly or indirectly ownsholds exceeds certain thresholds, such unitholder wouldU.S. Holder will be required to file IRS Form 8621 with its annual U.S.


federal income tax return to report its ownership of our units.



Certain elections, In addition, if a Non-Electing Holder, who is an individual, dies while owning our units, such asNon-Electing Holder’s successor generally would not receive a qualified electing fund (or step-up in tax basis with respect to such unitsQEF) election or mark to market election, may be available to a unitholder if we were classified as a PFIC. If we determine that we are or will be a PFIC, we will provide unitholders with information concerning the potential availability of such elections..

U.S. Holders are urged to consult their tax advisors regarding the PFIC rules, including the PFIC annual reporting requirements, as well as the applicability, availability and advisability of, and procedure for, making QEF, Mark-to-Market and other available elections with respect to us, and the U.S. federal income tax consequences of making such elections.

U.S. Return Disclosure Requirements for U.S. Individual Holders
U.S. Individual Holders who hold certain specified foreign financial assets, including stock in a foreign corporation that is not held in an account maintained by a financial institution, with an aggregate value in excess of $50,000 on the last day of a taxable year, or $75,000 at any time during that taxable year, may be required to report such assets on IRS Form 8938 with their U.S. federal income tax return for that taxable year. This reporting requirement does not apply to U.S. Individual Holders who report their ownership of our units under the PFIC annual reporting rules described above. Penalties apply for failure to properly complete and file IRS Form 8938. U.S. Individual Holders are encouraged to consult with their tax advisors regarding the possible application of this disclosure requirement to their investment in our units.

United States Federal Income Taxation of Our Subsidiary CorporationsNon-U.S. Holders
Our subsidiary Teekay LNG Holdco L.L.C. is wholly-owned byA beneficial owner of our units (other than a U.S. partnership, and our subsidiary Teekay BLT Finance Corporation is 69% indirectly owned by Teekay LNG Holdco L.L.C.. Each of these entities has been classifiedincluding any entity or arrangement treated as a corporationpartnership for U.S. federal income tax purposes andpurposes) that is not a U.S. Holder is a Non-U.S. Holder.

Distributions
In general, a Non-U.S. Holder will not be subject to U.S. federal income tax based on distributions received from us with respect to our units unless the rulesdistributions are effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, are attributable to foreign corporations described above under “Possible Classification as a Corporation - Taxation of Operating Income,” including, but not limited to, the 4% gross basis tax or the net basis tax if the Section 883 Exemption does not apply. We believepermanent establishment that the Section 883 Exemption would apply to our corporate subsidiaries only toNon-U.S. Holder maintains in the extent that it would apply to us if we wereUnited States). If a Non-U.S. Holder is engaged in a trade or business within the United States and the distributions are deemed to be treated as a corporation. As such, we believeeffectively connected to that trade or business, the Section 883 Exemption did not apply for 2017 and will not apply in 2018 or subsequent years and therefore, the 4% gross basis tax applied to our subsidiary corporation in 2017 and will apply to our subsidiary corporation in 2018 and subsequent years. In this regard, we estimate that weNon-U.S. Holder generally will be subject to approximately $100,000 or less of U.S. federal income tax on those distributions in 2018 and in each subsequent year basedthe same manner as if it were a U.S. Holder.
Sale, Exchange or Other Disposition of Units
In general, a non-U.S. Holder is not subject to U.S. federal income tax on any gain resulting from the amountdisposition of U.S. Source International Transportation Income our corporate subsidiary earned for 2017 and its expected U.S. Source International Transportation Income for 2018 and subsequent years. The amountunits unless (a) such gain is effectively connected with the Non-U.S. Holder’s conduct of such tax for which it would be liable for any year will depend upon the amount of income earned from voyages intoa trade or out ofbusiness within the United States (and, if required by an applicable income tax treaty, is attributable to a permanent establishment that the Non-U.S. Holder maintains in the United States) or (b) the Non-U.S. Holder is an individual who is present in the United States for 183 days or more during the taxable year in which such year, which, however,disposition occurs and meets certain other requirements. If a Non-U.S. Holder is engaged in a trade or business within the United States and the disposition of our units is deemed to be effectively connected to that trade or business, the Non-U.S. Holder generally will be subject to U.S. federal income tax on the resulting gain in the same manner as if it were a U.S. Holder.
Information Reporting and Backup Withholding

In general, distributions taxable as dividends with respect to, or the proceeds from a sale, redemption or other taxable disposition of, our units held by a Non-Corporate U.S. Holder will be subject to information reporting requirements, unless such distribution taxable as a dividend is paid and received outside the United States by a non-U.S. payor or non-U.S. middleman (within the meaning of U.S. Treasury Regulations), or such proceeds are effected through an office outside the U.S. of a broker that is considered a non-U.S. payor or non-U.S. middleman (within the meaning of U.S. Treasury Regulations). These amounts also generally will be subject to backup withholding if the Non-Corporate U.S. Holder:
fails to timely provide an accurate taxpayer identification number;
is notified by the IRS that it has failed to report all interest or distributions required to be shown on its U.S. federal income tax returns; or
in certain circumstances, fails to comply with applicable certification requirements.

Information reporting and backup withholding generally will not apply to distributions taxable as dividends on our units to a Non-U.S. Holder if such dividend is paid and received outside the United States by a non-U.S. payor or non-U.S. middleman (within the meaning of U.S. Treasury Regulations) or the Non-U.S. Holder properly certifies under penalties of perjury as to its non-U.S. status (generally on IRS Form W-8BEN, W-8BEN-E, W-8ECI, W-8EXP or W-8IMY, as applicable) and certain other conditions are met or the Non-U.S. Holder otherwise establishes an exemption.

Payment of proceeds to a Non-U.S. Holder from a sale, redemption or other taxable disposition of our units to or through the U.S. office of a broker, or through a broker that is considered a U.S. payor or U.S. middleman (within the meaning of U.S. Treasury Regulations), generally will be subject to information reporting and backup withholding, unless the Non-U.S. Holder properly certifies under penalties of perjury as to its non-U.S. status (generally on IRS Form W-8BEN, W-8BEN-E, W-8ECI, W-8EXP or W-8IMY, as applicable) and certain other conditions are met or the Non-U.S. Holder otherwise establishes an exemption.

Backup withholding is not withinan additional tax. Rather, a Non-Corporate U.S. Holder or Non-U.S. Holder generally may obtain a credit for any amount withheld against its complete control.

As non-U.S. entities classified as corporationsliability for U.S. federal income tax purposes, Teekay LNG Holdco L.L.C.(and obtain a refund of any amounts withheld in excess of such liability) by accurately completing and Teekay BLT Finance Corporation could be considered PFICs. However, we have receivedtimely filing a ruling from the IRS that Teekay LNG Holdco L.L.C. will be classified as a controlled foreign corporation (or a CFC) rather than a PFIC as long as it is wholly-owned by a U.S. partnership and we believe that Teekay BLT Finance Corporation will also be classified as a CFC rather than a PFIC because our U.S. partnership indirectly owns 69% of Teekay BLT Finance Corporation.

In past years, certain other of our subsidiaries were classified as corporations for U.S. federal income tax purposes. We have and will continue to takereturn with the position that these subsidiaries, to the extent they were owned by our U.S. partnership, should also have been treated as CFCs rather than PFICs. Moreover, we have and will continue to take the position that these subsidiaries were not PFICs at any time prior to being owned by our U.S. partnership. No assurance can be given, however, that the IRS, or a court of law, will accept this position or would not follow the Tidewater decision in interpreting the PFIC provisions under the Code (as discussed above).IRS.



Non-United States Tax Considerations
Marshall Islands Taxation
Because we and our controlled affiliates do not, and we do not expect that we and our controlled affiliates will, conduct business, operations, or transactions in the Republic of the Marshall Islands, neither we nor our controlled affiliates are subject to income, capital gains, profits or other taxation under current Marshall Islands law, other than taxes, fines, or fees due to (i) the incorporation, dissolution, continued existence, merger, domestication (or similar concepts) of legal entities registered in the Republic of the Marshall Islands, (ii) filing certificates (such as certificates of incumbency, merger, or redomiciliation) with the Marshall Islands registrar, (iii) obtaining certificates of good standing from, or certified copies of documents filed with, the Marshall Islands registrar, (iv) compliance with Marshall Islands law concerning vessel ownership, such as tonnage tax, or (v) non-compliance with requests made by the Marshall Islands registrar of corporations relating to our books and records and the books and records of our subsidiaries. As a result, distributions by controlled affiliates to us are not subject to Marshall Islands taxation.

Other Taxation
We and our subsidiaries are subject to taxation in certain non-U.S. jurisdictions because we or our subsidiaries are either organized, or conduct business or operations, in such jurisdictions, but we do not expect any such tax to be material. However, we cannot assure this result as tax laws in these or other jurisdictions may change or we may enter into new business transactions relating to such jurisdictions, which could affect our tax liability. Please read “Item 18 – Financial Statements: Note 11 – Income Tax.”

Canadian Federal Income Tax Considerations.Considerations

The following discussion is a summary of the material Canadian federal income tax considerations under the Income Tax Act (Canada) (or the Canada Tax Act) that we believe are relevant to holders of units who, for the purposes of the Canada Tax Act and the Canada-United States Tax Convention 1980 (or the Canada-U.S. Treaty), are at all relevant times resident in the United States and entitled to all of the benefits of the Canada - U.S. Treaty and who deal at arm’s length with us and Teekay Corporation (or U.S. Resident Holders). This discussion takes into account all proposed amendments to the Canada Tax Act and the regulations thereunder that have been publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof and assumes that such proposed amendments will be enacted substantially as proposed. However, no assurance can be given that such proposed amendments will be enacted in the form proposed or at all. This discussion assumes that Teekay LNG Partners L.P. is, and will continue to be, classified as a partnership for United States federal income tax purposes.

Teekay LNG Partners L.P. is considered to be a partnership under Canadian federal income tax law and therefore not a taxable entity for Canadian income tax purposes. A U.S. Resident Holder will not be liable to tax under the Canada Tax Act on any income or gains allocated by Teekay LNG Partners L.P. to the U.S. Resident Holder in respect of such U.S. Resident Holder in respect of such U.S. Resident Holder’s units, provided that for purposes of the Canada-U.S. Treaty, (a) Teekay LNG Partners L.P. does not carry on business through a permanent establishment in Canada for the purposes of the Canada Tax Act and (b) such U.S. Resident Holder does not hold such units in connection with a business carried on by such U.S. Resident Holder through a permanent establishment in Canada.Canada for purposes of the Canada-U.S. Treaty.

A U.S. Resident Holder will not be liable to tax under the Canada Tax Act on any income or gain from the sale, redemption or other disposition of such U.S. Resident Holder’s units, provided that, for purposes of the Canada-U.S. Treaty, such units do not, and did not at any time in the
twelve-month period preceding the date of disposition, form part of the business property of a permanent establishment in Canada of such U.S. Resident Holder.

We believe that the activities and affairs of Teekay LNG Partners L.P. are conducted in such a manner that Teekay LNG Partners L.P. is not carrying on business in Canada and that U.S. Resident Holders should not be considered to be carrying on business in Canada for purposes of the Canada Tax Act or the Canada-U.S. Treaty solely by reason of the acquisition, holding, disposition or redemption of our units. We intend that this is and continues to be the case, notwithstanding that Teekay Shipping Limited (a subsidiary of Teekay Corporation that is a non-resident of Canada) and Service Provider (an indirect subsidiary of Teekay LNG Partners L.P. that is a non-resident of Canada) provide certain services to Teekay LNG Partners L.P. and obtain some or all such services under subcontracts with Canadian service providers. If the arrangements we have entered into result in Teekay LNG Partners L.P. being considered to carry on business in Canada for purposes of the Canada Tax Act, U.S. Resident Holders would be considered to be carrying on business in Canada and may be required to file Canadian tax returns, andsubject to any relief provided under the Canada-U.S. Treaty, would be subject to taxation in Canada on any income from such business that is considered to be attributable to the business carried on by Teekay LNG Partners L.P. in Canada. The Canada-U.S. Treaty contains a permanent establishmenttreaty benefit denial rule which may have the effect of denying relief thereunder from Canadian taxation to U.S. Resident Holders in respect of any income attributable to business carried on by us in Canada for purposes of the Canada-U.S. Treaty..

Although we do not intend to do so, there can be no assurance that the manner in which we carry on our activities will not change from time to time as circumstances dictate or warrant in a manner that may cause U.S. Resident Holders to be carrying on business in Canada for purposes of the Canada Tax Act. Further, the relevant Canadian federal income tax law may change by legislation or judicial interpretation and the Canadian taxing authorities may take a different view than we have of the current law.

Other Taxation
WeIt is the responsibility of each unitholder to investigate the legal and our subsidiaries are subjecttax consequences, under the laws of pertinent jurisdictions, including Canada, of an investment in us. Accordingly, each unitholder is urged to taxation in certain non-U.S. jurisdictions because we or our subsidiaries are either organized, or conduct business or operations, inconsult, and depend upon, such jurisdictions, but we do not expect any suchunitholder’s tax to be material. However, we cannot assure this result as tax laws in thesecounsel or other jurisdictionsadvisor with regard to those matters. Further, it is the responsibility of each unitholder to file all state, local and non-U.S., as well as U.S. federal tax returns, that may change or we may enter into new business transactions relating tobe required of such jurisdictions, which could affect our tax liability.

Item 11.Quantitative and Qualitative Disclosures About Market Risk
Interest Rate Risk
We are exposed to the impact of interest rate changes primarily through our borrowings that require us to make interest payments based on LIBOR, EURIBOR or NIBOR. Significant increases in interest rates could adversely affect our operating margins, results of operations and our ability to service our debt. From time to time, we use interest rate swaps to reduce our exposure to market risk from changes in interest rates. The principal objective of these contracts is to minimize the risks and costs associated with our floating-rate debt.

We are exposed to credit loss in the event of non-performance by the counterparties to the interest rate swap agreements. In order to minimize counterparty risk, we only enter into derivative transactions with counterparties that are rated A- or better by Standard & Poor’s or A3 or better by Moody’s at the time of the transactions. In addition, to the extent practical, interest rate swaps are entered into with different counterparties to reduce concentration risk.

The table below provides information about our financial instruments at December 31, 2017,2018, that are sensitive to changes in interest rates.rates, including our long-term debt, obligations related to capital leases and interest rate swaps, but excluding any amounts related to our equity-accounted investments. For long-term debt and obligations related to capital leases, the table presents principal payments and related weighted-average interest rates by expected maturity dates. For interest rate swaps, the table presents notional amounts and weighted-average interest rates by expected contractual maturity dates. The expected contractual maturity dates do not reflect potential prepayments of long-term debt and obligations related to capital leases as well as the potential exercise of early termination options for certain of our interest rate swaps.

(1)Rate refers to the weighted-average effective interest rate for our long-term debt and obligations related to capital leases, including the margin we pay on our floating-rate debt and the average fixed pay rate for our interest rate swap agreements. The average interest rate for our obligations related to capital leases is the weighted-average interest rate implicit in our lease obligations at the inception of the leases. The average fixed pay rate for our interest rate swaps excludes the margin we pay on our drawn floating-rate debt, which as of December 31, 20172018 ranged from 0.30% to 3.25%. Please read “Item 18 – Financial Statements: Note 910 – Long-Term Debt.”
(2)Interest payments on U.S. Dollar-denominated debt and interest rate swaps are based on LIBOR. The repayment amounts exclude a non-interest bearing loan of $10.0 million and give effect to the refinancing completed in February 2018 of one of our revolving facilities scheduled to mature in 2018 with a new $197 million revolving credit facility maturing in 2022.

(6)The amount of obligations related to capital leases represents the present value of minimum lease payments together with our purchase obligation, as applicable.
(7)The average interest rate is the weighted-average interest rate implicit in the obligations related to our fixed-rate capital leases at the inception of the leases.
(8)The table above does not reflect our interest rate swaption agreements, whereby we have a one-time option to enter into an interest rate swap at a fixed rate with a third party, and the third party has a one-time option to require us to enter into an interest rate swap at a fixed rate. If we or the third party exercises its option, there will be cash settlements for the fair value of the interest rate swap in lieu of taking delivery of the actual interest rate swap. The net fair value of the interest rate swaption agreements as at December 31, 2017 was nominal. Please read “Item 18 – Financial Statements: Note 12 – Derivative Instruments and Hedging Activities”.

The cyclical nature of the spot market may cause significant increases or decreases the otherwise fixed-rate established in the charter depending on the spot charter rates thatrevenues we would have earned had we traded the vesselearn from these vessels trading in the spot tanker market. The time-charter contract expires in August 2025, although the charterer has the right to terminate the time-charter in July 2018. We have entered into an agreement with Teekay Corporation under which Teekay Corporation pays us any amounts payable to the charterer as a result of spot rates being below the fixed rate, and we pay Teekay Corporation any amounts payable to us from the charterer as a result of spot rates being in excess of the fixed rate. The amounts payable to or receivable from Teekay Corporation are settled at the end of each year. At December 31, 2017, the fair value of this derivative asset was $1.6 million and the change from December 31, 2016 to the reporting period has been reported in realized and unrealized loss on non-designated derivative instruments.
Foreign Currency Fluctuations
Our functional currency is U.S. Dollars because primarilynearly all of our revenues and most of our operating costs are in U.S. Dollars. Our results of operations are affected by fluctuations in currency exchange rates. The volatility in our financial results due to currency exchange rate fluctuations is attributed primarily to foreign currency revenues and expenses, our Euro-denominated loans and restricted cash deposits and our NOK-denominated bonds. A portion of our voyage revenues are denominated in Euros. A portion of our vessel operating expenses and general and administrative expenses are denominated in Euros, which is primarily a function of the nationality of our crew and administrative staff. We have Euro-denominated interest expense and Euro-denominated interest income related to our Euro-denominated loans of 194.1169.0 million Euros ($233.0193.8 million) and Euro-denominated restricted cash deposits of 19.921.6 million Euros ($23.924.8 million), respectively, as at December 31, 2017.2018. We also incur NOK-denominated interest expense on our NOK-denominated bonds; however, we entered into cross-currencycross currency swaps and pursuant to these swaps we receive the principal amount in NOK on the maturity date of the swap, in exchange for payment of a fixed U.S. Dollar amount. In addition, the cross-currencycross currency swaps exchange a receipt of floating interest in NOK based on NIBOR plus a margin for a payment of U.S. Dollar fixed interest. The purpose of the cross-currencycross currency swaps is to economically hedge the foreign currency exposure on the payment of interest and principal of our NOK bonds due in 20182020 through 2021,2023, and to economically hedge the interest rate exposure. We have not designated, for accounting purposes, these cross-currencycross currency swaps as cash flow hedges of the NOK-denominated bonds due in 2018 through 2021. Please read “Item 18 – Financial Statements: Note 1213 – Derivative Instruments and Hedging Activities.” At December 31, 2017,2018, the fair value of the cross-currencycross currency swaps derivative liabilities was $50.5$29.1 million and the change from December 20162017 to the reporting period has been reported in foreign currency exchange gain (loss) gain in the consolidated statements of income. As a result, fluctuations in the Euro and NOK relative to the U.S. Dollar have caused, and are likely to continue to cause, fluctuations in our reported voyage revenues, vessel operating expenses, general and administrative expenses, interest expense, interest income, realized and unrealized loss on non-designated derivative instruments and foreign currency exchange gain.gain (loss).
Item 12.Description of Securities Other than Equity Securities
Not applicable.
PART II
Item 13.Defaults, Dividend Arrearages and Delinquencies
None.
Item 14.Material Modifications to the Rights of Unitholders and Use of Proceeds
Not applicable.
Item 15.Controls and Procedures
We maintain disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities and Exchange Act of 1934, as amended (or the Exchange Act)) that are designed to ensure that (i) information required to be disclosed in our reports that are filed or submitted under the Exchange Act, are recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and (ii) information required to be disclosed by us in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including the principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

We conducted an evaluation of our disclosure controls and procedures under the supervision and with the participation of the Chief Executive Officer and Chief Financial Officer of the Service Provider. Based on the evaluation, the Chief Executive Officer and Chief Financial Officer of the Service Provider concluded that our disclosure controls and procedures are effective as of December 31, 2017.2018.



The Chief Executive Officer and Chief Financial Officer of the Service Provider do not expect that our disclosure controls or internal controls will prevent all errors and all fraud. Although our disclosure controls and procedures were designed to provide reasonable assurance of achieving their objectives, a control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within us have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based partly on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.
Management’s Report on Internal Control over Financial Reporting
Our management is responsible for establishing and maintaining for us adequate internal control over financial reporting.

Our internal controls are designed to provide reasonable assurance as to the reliability of our financial reporting and the preparation and presentation of the consolidated financial statements for external purposes in accordance with accounting principles generally accepted in the United States. Our internal control over financial reporting includeincludes those policies and procedures that: 1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; 2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of the financial statements in accordance with U.S. generally accepted accounting principles, and that our receipts and expenditures are being made in accordance with authorizations of management and the directors; and 3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our consolidated financial statements.

We conducted an evaluation of the effectiveness of our internal control over financial reporting based upon the framework in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. This evaluation included review of the documentation of controls, evaluation of the design effectiveness of controls, testing of the operating effectiveness of controls and a conclusion on this evaluation.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements even when determined to be effective and can only provide reasonable assurance with respect to financial statement preparation and presentation. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures may deteriorate. Based on the evaluation, management has determined that the internal control over financial reporting was effective as of December 31, 2017.2018.

Our independent auditors, KPMG LLP, an independent registered public accounting firm, have audited the accompanying consolidated financial statements and the effectiveness of our internal control over financial reporting.reporting as of December 31, 2018. Their attestation report on the effectiveness of our internal control over financial reporting can be found on page F-2 of this Annual Report.

There were no changes in our internal controls that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting (as defined in Rule 13a – 15 (f) under the Exchange Act) that occurred during the year ended December 31, 2017.2018.

In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Partnership as of December 31, 20172018 and 2016,2017, and the results of its operations and its cash flows for each of the years in the three‑year period ended December 31, 2017,2018, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Partnership’s internal control over financial reporting as of December 31, 2017,2018, based on the criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated April 16, 20185, 2019 expressed an unqualified opinion on the effectiveness of the Partnership’s internal control over financial reporting.
Change in Accounting Principle
As discussed in Note 2 to the consolidated financial statements, the Partnership has changed its accounting policies for revenue recognition as of January 1, 2018 due to the adoption of ASU 2014-09 - Revenue from Contracts with Customers, and the classification of restricted cash and final settlements on cross currency swap agreements on the consolidated statements of cash flows for 2018 and comparative periods due to the adoption of ASU 2016-18 - Statement of Cash Flows: Restricted Cash andASU 2016-15 - Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments, respectively.
Basis for Opinion
These consolidated financial statements are the responsibility of the Partnership’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Partnership in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB and in accordance with the ethical requirements that are relevant to our audit of the consolidated financial statements in Canada.PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.
We have served as the Partnership’s auditor since 2011.

In our opinion, the Partnership maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017,2018, based on the criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Partnership as of December 31, 20172018 and 2016,2017, the related consolidated statements of income, comprehensive income, cash flows, and changes in total equity for each of the years in the three-year period ended December 31, 2017,2018, and the related notes (collectively, the consolidated financial statements), and our report dated April 16, 20185, 2019 expressed an unqualified opinion on those consolidated financial statements.

Basis for Opinion

The Partnership’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Partnership’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Partnership in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB and in accordance with the ethical requirements that are relevant to our audit of the consolidated financial statements in Canada.

PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’sAn entity’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

TEEKAY LNG PARTNERS L.P. AND SUBSIDIARIES
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
(all tabular amounts stated in thousands of U.S. Dollars, except unit and per unit data or unless otherwise indicated)


1.Summary of Significant Accounting Policies
Basis of Presentationpresentation
TheThese consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (or GAAP). These financial statementsThey include the accounts of Teekay LNG Partners L.P. (or the Partnership), which is a limited partnership organized under the laws of the Republic of The Marshall Islands, its wholly-owned or controlled subsidiaries and any variable interest entities (or VIEs) of which it is the primary beneficiary. beneficiary (collectively, the Partnership).

The preparation of these consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimates.

Significant intercompany balances and transactions have been eliminated upon consolidation.

In addition, becausecertain comparative figures have been reclassified to conform to the Partnership has determined thatpresentation adopted in the entities that have financed certain ofcurrent period relating to a change in the Partnership's LNG carriers or LNG carrier newbuildings through sale leasebackreportable segments (see Note 4) and to reclassifications of certain related party transactions are VIEs that should be consolidated,between vessel operating expenses and general and administrative expenses in the presentation of the sale leaseback transactions in thePartnership's consolidated statements of cash flows has been adjusted to reflect these transactions as financing activities instead of investing activities in the current and comparative period. This hasincome that resulted in a decrease in net investing cash flowvessel operating expenses and an offsetting increase in general and administrative expenses of $355$1.6 million and an increase in net financing cash flow of $355$0.7 million for the yearyears ended December 31, 2016.2017 and December 31, 2016, respectively.

Foreign currency

The consolidated financial statements are stated in U.S. Dollars and the functional currency of the Partnership and its subsidiaries is the U.S. Dollar. Transactions involving other currencies during the year are converted into U.S. Dollars using the exchange rates in effect at the time of the transactions. At the balance sheet date, monetary assets and liabilities that are denominated in currencies other than the U.S. Dollar are translated to reflect the year-end exchange rates. Resulting gains or losses are reflected separatelyin foreign currency exchange gain (loss) in the accompanying consolidated statements of income.
Operating revenues and expenses
The lease element ofRevenues

Time charters

Revenues from time-charters and bareboat charters accounted for as operating leases are recognized by the Partnership on a straight-line basis daily over the term of the charter. Upon commencement of a time charter accounted for as a direct financing lease, the applicablecarrying value of the vessel operates underis derecognized and the charter.net investment in the lease is recognized. The lease element of time-charter hire receipts is allocated to the Partnership’s time-charters that are accounted for as direct financing leases is reflected on the balance sheets as net investments in direct financing leases. The lease element is recognizedreceivable and voyage revenues over the term of the lease term using the effective interest rate method and is included in voyage revenues.method. The Partnership recognizes revenues from the non-lease element of time-charter contracts as services are performed.hire receipts is recognized by the Partnership on a straight-line basis daily over the term of the charter. For time-charter contracts where the charterer is responsible for the operation of the vessel, the Partnership offsets any vessel operating expenses it incurs against reimbursements from the charterer. The Partnership does not recognize revenues during days that the vessel is off-hire or if collectability of receipts of charter payments from charterers is not reasonably assured. When the time charter contains a profit-sharing agreement, the Partnership recognizes the profit-sharing or contingent revenues when the contingency is resolved.

Voyage charters

Revenues from voyage charters are recognized on a proportionate performance method. The Partnership uses a discharge-to-discharge basis in determining proportionate performance for all spot voyages that contain a lease and a load-to-discharge basis in determining proportionate performance for all spot voyages that do not contain a lease. The Partnership does not begin recognizing revenue until a charter has been agreed to by the customer, even if the vessel has discharged its cargo and is sailing to the anticipated load port on its next voyage. The consolidated balance sheets reflect, in other current assets, the accrued portion of revenues for those voyages that commence prior to balance sheet date and complete after the balance sheet date.

Bareboat charters

Revenues from bareboat charters accounted for as operating leases are recognized by the Partnership on a straight-line basis daily over the term of the charter. Upon commencement of a bareboat charter accounted for as a direct financing lease, the carrying value of the vessel is derecognized and the net investment in the lease is recognized. Bareboat hire receipts are allocated to the lease receivable and voyage revenues over the term of the lease using the effective interest rate method. The Partnership does not recognize revenues if collectability of charter hire payments is not reasonably assured.

Operating expenses

Voyage expenses areinclude all expenses unique to a particular voyage, including bunker fuel expenses, port fees, cargo loading and unloading expenses, canal tolls, agency fees and commissions. The Partnership, as shipowner, pays voyage expenses under voyage charters. The Partnership’s customers pay voyage expenses under time charters, except when the vessel is off-hire during the term of a time-charter, in which case the Partnership pays voyage expenses.


Vessel operating expenses include crewing, ship management services, repairs and maintenance, insurance, stores, lube oils and communication expenses.

Voyage expenses and vessel operating expenses are recognized when incurred.incurred except when the Partnership incurs pre-operational costs related to the repositioning of a vessel (i) that relates directly to a specific customer contract, (ii) that generates or enhances resources of the Partnership that will be used in satisfying performance obligations in the future; and (iii) where such costs are expected to be recovered via the customer contract. In this case, such costs are deferred and amortized over the duration of the customer contract.

The Partnership recognizes the expense from vessels accounted for as operating leases, which is included in time-charter hire expense, on a straight-line basis over the firm period of the charters.

Cash and cash equivalents

The Partnership classifies all highly-liquidhighly liquid investments with aan original maturity date of three months or less when purchased as cash and cash equivalents.

Restricted Cashcash

The Partnership maintains restricted cash deposits relating to certain term loans, collateral for derivatives, project tenders, leasing arrangements, amounts received from charterers to be used only for dry-docking expenditures and emergency repairs and other obligations.

Accounts receivable and allowance for doubtful accounts

Accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is the Partnership’s best estimate of the amount of probable credit losses in existing accounts receivable. The Partnership determines the allowance based on historical write-off experience and customer economic data. The Partnership reviews the allowance for doubtful accounts regularly and past due balances are reviewed for collectability. Account balances are charged against the allowance when the Partnership believes that the receivable will not be recovered. The consolidated balance sheets reflect amounts where the right to consideration is conditioned upon the passage of time as "accounts receivable," and reflect accrued revenue where the right to consideration is conditioned upon something other than the passage of time as "other current assets."

Other loan receivables

The Partnership’s advances to equity-accounted joint ventures and any other investments in loan receivables are recorded at cost. The Partnership analyzes its loans for collectability during each reporting period. A loan loss provision is recorded,recognized, based on current information and events, if it is probable that the Partnership will be unable to collect all amounts due according to the contractual terms of the loan agreement. Factors the Partnership considers in determining


TEEKAY LNG PARTNERS L.P. AND SUBSIDIARIES
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
(all tabular amounts stated in thousands of U.S. Dollars, except unit and per unit data or unless otherwise indicated)

that if a loan loss provision is required include, among other things, an assessment of the financial condition of the debtor, payment history of the debtor, general economic conditions, the credit rating of the debtor (when available), any information provided by the debtor regarding its ability to repay the loan, and the fair value of the underlying collateral. When a loan loss provision is recorded,recognized, the Partnership measures the amount of the loss provision based on the present value of expected future cash flows discounted at the loan’s effective interest rate and recognizes the resulting provisionloss in the consolidated statements of income. The carrying value of the loansloan is adjusted each subsequent period to reflect any changes in the present value of the expected future cash flows, which may result in increases or decreases to the loan loss provision.

The following table contains a summary of the carrying value of the Partnership’s financing receivables by type of borrower, the method by which the Partnership monitors the credit quality of its financing receivables on a quarterly basis and the grade as at December 31, 2018.

Vessels and equipment

All pre-delivery costs incurred during the construction of newbuildings, including interest and supervision and technical costs, are capitalized. The acquisition cost and all costs incurred to restore used vessels purchased by the Partnership to the standards required to properly service the Partnership’s customers are capitalized.

Interest costs capitalized to vessels and equipment for the years ended December 31, 2018, 2017 and 2016 and 2015 aggregated $14.8 million, $13.9 million and $9.9 million, and $8.2 million, respectively.


Vessel capital modifications include the addition of new equipment or certain modifications to the vessel which are aimed at improving or increasing the operational efficiency and functionality of the asset. This type of expenditure is amortizedcapitalized and depreciated over the estimated useful life of the modification. Expenditures covering recurring routine repairs and maintenance are expensed as incurred.

Depreciation is calculated on a straight-line basis over a vessel’s estimated useful life, less an estimated residual value. Depreciation is calculated using an estimated useful life of 25 years for conventional tankers, 30 years for liquefied petroleum gas (or LPG) carriers and 35 years for liquefied natural gas (or LNG) carriers, from the date the vessel is delivered from the shipyard, or a shorter period if regulations prevent the Partnership from operating the vessels for 25 years, 30 years, or 35 years, respectively. Depreciation of vessels and equipment, excluding amortization of dry-docking expenditures, for the years ended December 31, 2018, 2017 and 2016 and 2015 aggregated $115.5 million, $96.7 million $86.6 million and $83.4$86.6 million, respectively. Depreciation and amortization includes depreciation on all owned vessels and amortization of vessels accounted for as capital leases.

Generally, the Partnership dry docks each of its vessels every two and a half to five years. In addition, a shipping society classification intermediate survey is performed on the Partnership’s LNG and LPG carriers between the second and third year of the five-year dry-docking cycle. The Partnership capitalizes certain costs incurred during dry docking and for the survey and amortizes those costs on a straight-line basis from the completion of a dry docking or intermediate survey overto the estimated useful lifecompletion of the next dry dock.docking. The Partnership includes in capitalized dry docking those costs incurred as part of the dry docking to meet classification and regulatory requirements, or expenditures that either add economic life to the vessel, increase the vessel’s earning capacity or improve the vessel’s operating efficiency.requirements. The Partnership expenses costs related to routine repairs and maintenance performed during dry docking that do not improve operating efficiency or extend the useful lives of the assets.docking.

Vessels and equipment that are “held for use”intended to be held and used in the Partnership's business are assessed for impairment when events or circumstances indicate the carrying amount of the asset may not be recoverable. If the asset’s net carrying value exceeds the net undiscounted cash flows expected to be generated over its remaining useful life, the carrying amount of the asset is reduced to its estimated fair value. The estimated fair value for the Partnership’s impaired vessels is determined using discounted cash flows or appraised values. In cases where an active second handsecond-hand sale and purchase market does not exist, the Partnership uses a discounted cash flow approach to estimate the fair value of an impaired vessel. In cases where an active second handsecond-hand sale and purchase market exists, an appraised value is used to estimate the fair value of an impaired vessel. An appraised value is generally the amount the Partnership would expect to receive if it were to sell the vessel. Such appraisal is normally completed by the Partnership.Partnership and is based on second-hand sale and purchase data.

Vessels and equipment that are "held for sale" are measured at the lower of their carrying amount or fair value less costs to sell and are not depreciated while classified as held for sale. Interest and other expenses and related liabilities attributable to vessels and equipment classified as held for sale or to their related liabilities, continue to be recognized as incurred.

Gains on vessels sold and leased back under capital leases with lessor entities that are not considered VIEs are deferred and amortized over the remaining term of the capital lease. Losses on vessels sold and leased back under capital leases are recognized immediately when the fair value of the vessel at the time of a sale-leaseback transaction is less than its book value. In such case, the Partnership would recognize a loss in the amount by which book value exceeds fair value.
Investments in and advances to equity-accounted joint ventures


TEEKAY LNG PARTNERS L.P. AND SUBSIDIARIES
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
(all tabular amounts stated in thousands of U.S. Dollars, except unit and per unit data or unless otherwise indicated)
Equity-accounted investments

The Partnership’s investments in certain joint ventures, in which the Partnership has the ability to exercise significant influence over the operating and financial policies of the entity, are accounted for using the equity method of accounting. Under the equity method of accounting, investments are stated at initial cost and are adjusted for subsequent additional investments and the Partnership’s proportionate share of earnings or losses and distributions. In addition, the Partnership’s advances to equity-accounted joint ventures are recorded at cost. The Partnership evaluates its investment in and advances to equity-accounted joint venturesinvestments for impairment when events or circumstances indicate that the carrying value of such investments may have experienced an other-than-temporary decline in value below its carrying value. If an equity-accounted investment is impaired and if the estimated fair value is less than theits carrying value, the carrying value is written down to its estimated fair value and the resulting impairment is recorded in the Partnership’s consolidated statements of income. The Partnership’s maximum exposure to loss is the amount it has invested in its equity-accounted for investments.

Debt issuance costs related to a recognized debt liability, including fees, commissions and legal expenses, are deferred and presented as a direct reduction from the carrying amount of that debt liability and amortized on an effective interest rate method over the term of the relevant loan. Debt issuance costs relatedthat are not attributable to loan facilities without a recognizedspecific debt liability or where the debt issuance costs exceed the carrying value of the related debt liability (primarily undrawn revolving credit facilities) are deferred and presented as other non-current assets in the Partnership's

consolidated balance sheets. Amortization of debt issuance costs is included in interest expense.expense in the Partnership’s consolidated statements of income.

Fees paid to substantially amend a non-revolving credit facility shall beare associated with the extinguishment of the old debt instrument and included in determining the debt extinguishment gain or loss to be recognized. AnyIn addition, any unamortized debt issuance costs would beare written off. If the amendment is considered not to be a substantial amendment, then the fees would be associated with the replacement or modified debt instrument and, along with any existing unamortized premium, or discount and unamortized debt issuance costs, would be amortized as an adjustment of interest expense over the remaining term of the replacement or modified debt instrument using the effective interest method. Other related costs incurred with third parties directly related to the modification, other than the loan amendment fee, are expensed as incurred.

Fees paid to amend a revolving credit facilitiesfacility are deferred and amortized over the term of the modified revolving credit facility. If the borrowing capacity underof the revolving credit facility is increasedincreases as a result of the amendment, unamortized loandebt issuance costs of the original revolving credit facility would be deferred andare amortized over the remaining term of the modified revolving credit facility. If the borrowing capacity is decreasedof the revolving credit facility decreases as a result of the amendment, a proportionate amount, based on the reduction in borrowing capacity, of the unamortized debt issuance costs of the original revolving credit facility would beare written off and the remaining amount would be deferred andis amortized over the remaining term of the modified revolving credit facility.

Goodwill and intangible assets

Goodwill is not amortized but is reviewed for impairment at the reporting unit level on an annual basis or more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. A reporting unit is a component of the Partnership that constitutes a business for which discrete financial information is available and regularly reviewed by management. When goodwill is reviewed for impairment, the Partnership may elect to assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. Alternatively, the Partnership may bypass this step and use a fair value approach to identify potential goodwill impairment and, when necessary, measure the amount of impairment. The Partnership uses a discounted cash flow model to determine the fair value of reporting units, unless there is a readily determinable fair market value. The Partnership adopted ASU 2017-04, Simplifying the Test for Goodwill Impairment, effective October 1, 2018. Consequently, goodwill impairment is measured as the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying value of goodwill.

Customer-related intangible assets are amortized over the expected life of a customer contract. The amount amortized each year is weighted based on the projected revenue to be earned under the contracts. Intangible assets are assessed for impairment when and if impairment indicators exist. An impairment loss is recognized if the carrying amount of an intangible asset is not recoverable and its carrying amount exceeds its fair value.

The Partnership’s finite life intangible assets consist of acquired time-charter contracts that are amortized on a straight-line basis over the remaining term of the time-charters. Finite life intangible assets are assessed for impairment when events or circumstances indicate that the carrying value may not be recoverable.
Derivative instruments

All derivative instruments are initially recorded at fair value as either assets or liabilities in the accompanying consolidated balance sheetsheets and subsequently remeasured to fair value each period end, regardless of the purpose or intent for holding the derivative. The method of recognizing the resulting gain or loss is dependent on whether the derivative contract is designed to hedge a specific risk and whether the contract qualifies for hedge accounting.

When a derivative is designated as a cash flow hedge, the Partnership formally documents the relationship between the derivative and the hedged item. This documentation includes the strategy and risk management objective for undertaking the hedge and the method that will be used to assess the effectiveness of the hedge. Any hedge ineffectiveness is recognized immediately in earnings, as are any gains and losses on the derivative that are excluded from the assessment of hedge effectiveness. The Partnership does not apply hedge accounting if it is determined that the hedge was not effective or will no longer be effective, the derivative was sold or exercised, or the hedged item was sold, repaid or no longer possibleprobable of occurring.

For derivative financial instruments designated and qualifying as cash flow hedges, changes in the fair value of the effective portion of the derivative financial instruments are initially recorded as a component of accumulated other comprehensive income in total equity. In the periods when the hedged items affect earnings, the associated fair value changes on the hedging derivatives are transferred from total equity to the corresponding earnings line item (e.g. interest expense) in the Partnership’s consolidated statements of income. The ineffective portion of the change in fair value of the derivative financial instruments is immediately recognized in the corresponding earnings line item in the Partnership’s consolidated statements of income. If a cash flow hedge is terminated and the originally hedged item is still considered possibleprobable of occurring, the gains and losses initially recognized in total equity remain there until the hedged item impacts earnings, at which point they are transferred to the corresponding earnings line item (e.g. interest expense) in the

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
(all tabular amounts stated in thousands of U.S. Dollars, except unit and per unit data or unless otherwise indicated)

Partnership’s consolidated statements of income. If the hedged items are no longer possibleprobable of occurring, amounts recognized in total equity are immediately transferred to the earnings item in the Partnership’s consolidated statements of income.

For derivative financial instruments that are not designated or that do not qualify as hedges under Financial Accounting Standards Board (or FASB) Accounting Standards Codification (or ASC) 815, Derivatives and Hedging, the changes in the fair value of the derivative financial instruments are recognized in earnings. Gains and losses from the Partnership’s non-designated interest rate swaps, non-designated interest rate swaptions, and the Partnership’s agreement with Teekay Corporation for the Suezmax tanker the Toledo Spirit (see Note 11c)12d) are recorded in realized and unrealized loss on non-designated derivative instruments in the Partnership’s consolidated statements of income. Gains and

losses from the Partnership’s cross-currencycross currency swaps are recorded in foreign currency exchange gain (loss) gain in the Partnership’s consolidated statements of income.

Unit-based compensation

The Partnership grants restricted unit awards as incentive-based compensation under the Teekay LNG Partners L.P. 2005 Long-Term Incentive Plan to certain of the Partnership’s employees and to certain employees of Teekay Corporation’s subsidiaries that provide services to the Partnership and its subsidiaries. The Partnership measures the cost of such awards using the grant date fair value of the award and recognizes that cost, net of estimated forfeitures, over the requisite service period. The requisite service period consists of the period from the grant date of the award to the earlier of the date of vesting or the date the recipient becomes eligible for retirement. For unit-based compensation awards subject to graded vesting, the Partnership calculates the value of the award as if it was one single award with one expected life and amortizes the calculated expense for the entire award on a straight-line basis over the requisite service period. The compensation cost of the Partnership’s unit-based compensation awards is reflected in general and administrative expenses in the Partnership’s consolidated statements of income.

Income taxes

The Partnership accounts for income taxes using the liability method. All but twoUnder the liability method, deferred tax assets and liabilities are recognized for the anticipated future tax effects of temporary differences between the consolidated financial statement basis and the tax basis of the Partnership’s assets and liabilities using the applicable jurisdictional tax rates. A valuation allowance for deferred tax assets is recorded when it is more likely than not that some or all of the benefit from the deferred tax asset will not be realized. Three of the five Partnership’s Spanish-flagged vessels are subject to the Spanish Tonnage Tax Regime (or TTR). Under this regime, the applicable tax is based on the weight (measured as net tonnage) of the vessel and the number of days during the taxable period that the vessel is at the Partnership’s disposal, excluding time required for repairs. The income the Partnership receives with respect to the remaining two Spanish-flagged vessels is taxed in Spain at a rate of 25%. However, these two vessels are registered in the Canary Islands Special Ship Registry. Consequently, the Partnership is allowed a credit, equal to 90% of the tax payable on income from the commercial operation of these vessels, against the tax otherwise payable. This effectively results in an income tax rate of approximately 2.5% on income from the operation of these two Spanish-flagged vessels.

The Partnership recognizes the tax benefits of uncertain tax positions whenonly if it is more-likely-than-not that a tax position taken or expected to be taken in a tax return will be sustained upon examination by the taxing authorities, including resolution of any related appeals or litigation processes, based on the technical merits of the position. If aThe tax position meets the more-likely-than-not recognition threshold, it is measured to determine the amount of benefit to recognizebenefits recognized in the Partnership’s consolidated financial statements.statements from such positions are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. The Partnership recognizes interest and penalties related to uncertain tax positions in income tax expense in the Partnership’s consolidated statements of income.

Guarantees

Guarantees issued by the Partnership, excluding those that are guaranteeing its own performance, are recognized at fair value at the time the guarantees are issued and are presented in the Partnership’s consolidated balance sheets as other long-term liabilities. The liability recognized on issuance is amortized to other income on the Partnership’s consolidated statements of income over the term of the guarantee. If it becomes probable that the Partnership will have to perform under a guarantee, the Partnership will recognize an additional liability if the amount of the loss can be reasonably estimated.
2.Accounting Pronouncements
In May 2014, the FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers, (or ASU 2014-09). ASU 2014-09 will requirerequires an entity to recognize revenue when it transfers promised goods or services to customers at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This update creates a five-step model that requires entities to exercise judgment when considering the terms of the contract(s) which include (i) identifying the contract(s) with the customer, (ii) identifying the separate performance obligations in the contract, (iii) determining the transaction price, (iv) allocating the transaction price to the separate performance obligations, and (v) recognizing revenue as each performance obligation is satisfied. ASU 2014-09 isbecame effective for the Partnership as of January 1, 2018, and shallmay be applied, at the Partnership’s option, retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. The Partnership will adoptadopted ASU 2014-09 as a cumulative-effect adjustment as of thissuch date. The Partnership has elected to apply ASC 2014-09 only to those contracts that arewere not completed as of January 1, 2018. The Partnership has not identified any material impactthe following differences on its consolidated financial statements based on the work performed to date.adoption of ASU 2014-09:

In certain cases, the Partnership incurs pre-operational costs relating directly to a specific customer contract, that generate or enhance resources of the Partnership that will be used in satisfying performance obligations in the future, whereby such costs are expected to be recovered via the customer contract. Such costs are deferred and amortized over the duration of the customer contract. The Partnership previously expensed such costs as incurred unless the costs were directly reimbursable by the contract. This change increased net income by $1.1 million for the year ended December 31, 2018, and increased other assets by $3.5 million, investments in equity-accounted joint ventures by $0.3 million, and total equity by $3.8 million as at December 31, 2018. The cumulative increase to opening equity as at January 1, 2018 was $2.7 million.
The Partnership previously presented all accrued revenue as a component of accounts receivable. The Partnership has determined that if the right to such consideration is conditional upon something other than the passage of time, such accrued revenue should be presented

apart from accounts receivable. This had the impact of increasing other current assets and decreasing accounts receivable by $2.3 million at December 31, 2018. There was no cumulative impact to opening equity as at January 1, 2018.
In February 2016, the FASB issued Accounting Standards Update 2016-02, Leases (or ASU 2016-02). ASU 2016-02 establishes a right-of-use model that requires a lessee to record a right of use asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. For lessees, leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. ASU 2016-02 requires lessors to classify leases as a sales-type, direct financing, or operating lease. A lease is a sales-type lease if any one of five criteria are met, each of which indicate that the lease, in effect, transfers control of the underlying asset to the lessee. If none of those five criteria are met, but two additional criteria are both met, indicating that the lessor has transferred substantially

(all tabular amounts stated in thousands of U.S. Dollars, except unit and per unit data or unless otherwise indicated)

all of the risks and benefits of the underlying asset to the lessee and a third party, the lease is a direct financing lease. All leases that are not sales-type leases or direct financing leases are operating leases. ASU 2016-02 is effective January 1, 2019, with early adoption permitted. The Partnership currently intendsFASB issued an additional accounting standards update in July 2018 that made further amendments to adopt ASU 2016-02 effective January 1, 2018 usingaccounting for leases, including allowing the use of a transition approach whereby a cumulative effect adjustment is made as of the effective date, of January 1, 2018, with no retrospective effect. The Partnership will adopt ASU 2016-02 on January 1, 2019. To determine the cumulative effect adjustment, the Partnership haswill not reassessedreassess lease classification, initial direct costs for any existing leases and whether any expired or existing contracts are or contain leases, has not reassessed lease classification, and has not reassessed initial direct costs for any existing leases. The quarter in which the Partnership adopts ASU 2016-02 and the estimated impact from adoption contained below is based upon the expectation that FASB will issue an additional ASU prior to the filing of our consolidated financial statements for the first quarter of 2018. The Partnership is currently considering the potential impact of a delay in the finalization of this additional ASU on its adoption date. The Partnership has identified the following differences based on the work performed to date:differences:

The adoption of ASU 2016-02 will result in a change in the accounting method for the lease portion of the daily charter hire for the chartered-in vessels of the Partnership’s equity-accounted joint ventures accounted for as operating leases with firm periods of greater than one year.year for certain of the chartered-in vessels of the Partnership and the Partnership's equity-accounted joint ventures. Under ASU 2016-02, one of the equityPartnership's in-charter contracts currently accounted for as an operating lease will be treated as a right-of-use asset and a lease liability, which will result in an increase of the Partnership's assets and liabilities. The right-of-use asset and lease liability to be recognized on January 1, 2019 is $22.7 million. In addition, certain equity-accounted joint ventures will recognize a right-of-use asset and a lease liability on the balance sheet for these charters based on the present value of future minimum lease payments, whereas currently no right-of-use asset or lease liability is recognized. This will have the result of increasing the equity-accounted joint venture’s assets and liabilities. The pattern of expense recognition of chartered-in vessels is expected to remain substantially unchanged, unless the right of useright-of-use asset becomes impaired.
The adoption of ASU 2016-02 will result in the Partnership completing itsPartnership's lease classification assessment being determined when a lease commences instead of when the lease is entered into. The Partnership has entered into charters in prior periods for certain of its vessels currently under construction and which are expected to deliver over the period from 2018 to 2020.in 2019. Historically, for charters that were negotiated concurrently with the construction of the related vessels, the fair value of the constructed asset was presumed to be its newbuilding cost and no gain or loss was recognized on commencement of the charter if such charters were classified as direct finance leases. OnSubsequent to the adoption of ASU 2016-02, the fair value of the vessel iswill be determined based on information available at the lease commencement date and any difference in the fair value of the ship upon commencement of the charter and its carrying value is recognized as a gain or loss upon commencement of the charter.
The adoption of ASU 2016-02 will result in the recognition of revenue from the reimbursement of scheduled dry-dock expenditures, where such charter contract is accounted for as an operating lease, occurring upon completion of the scheduled dry-dock, instead of ratably over the period between the previous scheduled dry-dock and the next scheduled dry-dock. The Partnership is in the process of determining which vessels this applies to and the cumulative impactdecrease to opening equity as at January 1, 2018.
The Partnership expects that certain pre-operational costs it currently expenses as incurred will be deferred and amortized over the contract term of a customer contract that the costs relate to. The Partnership is in the process of determining which pre-operational costs this applies to and the cumulative impact to opening equity as at January 1, 2018.2019 was $3.0 million.
In addition, direct financing lease payments received will be presented as an operating cash inflow instead of an investing cash inflow in the statement of cash flows.
In March 2016, the FASB issued Accounting Standards Update 2016-09, Improvements to Employee Share-Based Payment Accounting (or ASU 2016-09). ASU 2016-09 simplifies aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification on theconsolidated statements of cash flows. ASU 2016-09 became effective for the Partnership January 1, 2017. The impact of adopting this new accounting guidance is a change in the Partnership's presentation of cash payments for tax withholdings on share settled equity awards from an operating cash outflow to a financing cash outflow on the Partnership's statements of cash flows.

In June 2016, the FASB issued Accounting Standards Update 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses
on Financial Instruments (or ASU 2016-13). ASU 2016-13 replaces the incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. This update is effective for the Partnership January 1, 2020, with a modified-retrospective approach. The Partnership is currently evaluating the effect of adopting this new guidance.

In August 2016, the FASB issued Accounting Standards Update 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts
and Cash Payments (or ASU 2016-15), which, among other things, provides guidance on two acceptable approaches of classifying distributions received from equity-method investees in the statements of cash flows and application of the predominance principle on the cash flow statement classification of cash receipts and payments that have aspects of more than one class of cash flows. ASU 2016-15 isbecame effective for the Partnership as of January 1, 2018, with a retrospective approach.approach required on adoption. The Partnership is currently evaluatinghas elected to classify distributions received from equity method investees in the consolidated statements of cash flows based on the nature of the distribution. In addition, the adoption of ASU 2016-15 resulted in $25.7 million and $17.7 million of cross currency swap payments that were related to the principal repayment of long-term debt for the years ended December 31, 2017 and December 31, 2016, respectively, being reclassified from unrealized foreign currency exchange (gain) loss including the effect of adopting this new guidance.the termination of cross currency swaps in net operating cash flow, to scheduled repayments of long-term debt and settlement of related swaps in net financing cash flow for the year ended December 31, 2017 and to prepayments of long-term debt and settlement of related swaps for the year ended December 31, 2016 as the amounts related to the termination of final settlement of the cross currency swaps.

In November 2016, the FASB issued Accounting Standards Update 2016-18, Statement of Cash Flows: Restricted Cash (or(or ASU 2016-18)2016-18).
ASU 2016-18 requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts
generally described as restricted cash or restricted cash equivalents. Entities willare also be required to reconcile such total to amounts on the

In August 2017, the FASB issued Accounting Standards Update 2017-12, Derivatives and Hedging - Targeted Improvements to Accounting
for Hedging Activities (or(or ASU 2017-12)2017-12). ASU 2017-12 eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires, for qualifying hedges, the entire change in the fair value of a hedging instrument to be presented in the same income

The guidance also modifies the accounting for components excluded from the assessment of hedge effectiveness, eases documentation and assessment requirements and modifies certain disclosure requirements. ASU 2017-12 will bebecame effective for the Partnership as of January 1, 2019. The Partnership is currently evaluating the effect of adopting this new guidance.

In June 2016, the FASB issued Accounting Standards Update 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses
on Financial Instruments (or ASU 2016-13). ASU 2016-13 replaces the incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. This update is effective for the Partnership January 1, 2020, with a modified-retrospective approach required on adoption. The Partnership is currently evaluating the effect of adopting this new guidance.

In October 2017, the FASB issued Accounting Standards Update 2017-04, Simplifying the Test for Goodwill Impairment (or ASU 2017-04). Pursuant to this update, goodwill impairment is now measured as the amount by which a reporting unit's carrying value exceeds its fair value, not to exceed the carrying value of goodwill. This update eliminates previous guidance that required an entity to determine goodwill impairment by calculating the implied fair value of goodwill by hypothetically assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. ASU 2017-04 requires a prospective adoption approach and is effective for annual and interim periods beginning after December 15, 2019, with early adoption permitted. ASU 2017-04 was adopted by the Partnership on October 1, 2018, and such adoption did not have a material impact on the Partnership's consolidated financial statements and related disclosures.

In August 2018, the FASB issued Accounting Standards Update 2018-15, Intangibles-Goodwill and Other-Internal Use Software: Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract, (or ASU 2018-15). ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. ASU 2018-15 is effective for annual and interim periods beginning after December 15, 2019, with early adoption permitted. The Partnership elected to adopt ASU 2018-15 on October 1, 2018, and such adoption did not have a material impact on the Partnership’s consolidated financial statements and related disclosures.
3.Financial Instruments
Fair Value Measurements
a)Fair Value Measurements

The following methods and assumptions were used to estimate the fair value of each class of financial instrument:

Cash and cash equivalents and restricted cash – The fair value of the Partnership’s cash and cash equivalents and restricted cash approximates its carrying amounts reported in the consolidated balance sheets.

Interest rate swap/swaption and cross-currencycross currency swap agreements – The fair value of these derivative instruments of the Partnership is the estimated amount that the Partnership would receive or pay to terminate the agreements at the reporting date, taking into account current interest rates, foreign exchange rates and the current credit worthiness of both the Partnership and the derivative counterparties. The estimated amount is the present value of future cash flows. The Partnership transacts all of these derivative instruments through investment-grade rated financial institutions at the time of the transaction and requires notransaction. The Partnership's interest rate swap agreements do not require the Partnership to provide cash collateral fromto these institutions; however, cash collateral ismay be required by thesecertain institutions on some of the Partnership's cross-currencycross currency swap agreements and as at December 31, 2017,2018, the Partnership had $22.3pledged $6.8 million heldcash as collateral (December 31, 20162017$37.8$22.3 million), which has been recorded as restricted cash – current and long-term on the Partnership's consolidated balance sheets. Given the current volatility in the credit markets, it is reasonably possible that the amount recorded as a derivative asset or liability could vary by a material amount in the near term.

Other derivative – The Partnership’s other derivative agreement is between Teekay Corporation and the Partnership and relates to hire payments under the time-charter contract for the Suezmax tanker Toledo Spirit (see Note 11c)12d). The fair value of this derivative agreement is the estimated amount that the Partnership would receive or pay to terminate the agreement at the reporting date, based on the present value of the Partnership’s projection of future spot market tanker rates, which have been derived from current spot market tanker rates and l

ong-termlong-term historical average rates. As projections of future spot rates are specific to the Partnership, these are considered Level 3 inputs for the purposes of estimating the fair value.

Long-term receivable included in accounts receivable and other assets – The fair valuesvalue of the Partnership’s long-term loan receivable areis estimated using discounted cash flow analysis based on rates currently available for debt with similar terms and remaining maturities and the current credit worthiness of the counterparty.

Long-term debt – The fair values of the Partnership’s fixed-rate and variable-rate long-term debt are either based on quoted market prices or estimated using discounted cash flow analyses based on rates currently available for debt with similar terms and remaining maturities and the current credit worthiness of the Partnership.

Long-term obligations related to capital leases – The fair values of the Partnership's long-term obligations related to capital leases are estimated using discounted cash flow analyses, based on rates currently available for debt with similar terms and remaining maturities.

The Partnership categorizes the fair value estimates by a fair value hierarchy based on the inputs used to measure fair value. The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value as follows:


Level 1.Observable inputs such as quoted prices in active markets;
Level 2.Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and
Level 3.Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

The following table includes the estimated fair value and carrying value of those assets and liabilities that are measured at fair value on a recurring and non-recurring basis, as well as the estimated fair value of the Partnership’s financial instruments that are not accounted for at a fair value on a recurring basis.

(i)The advances to equity-accounted joint ventures together with the Partnership’s equity investments in the joint ventures form the net aggregate carrying value of the Partnership’s interests in the joint ventures in these consolidated financial statements. The fair values of the individual components of such aggregate interests are not determinable.
(ii)
As at December 31, 2017,2018, the estimated fair value of the non-interest bearing receivable is based on the remaining future fixed payments of $3.5$0.2 million, to be received from Royal Dutch Shell Plc (or Shell) (formerly BG International Limited) as part of the ship construction support agreement, and using an estimated discount rate of 8.0%. As there is no market rate for the equivalent of an unsecured non-interest bearing receivable from Shell, the discount rate is based on unsecured debt instruments of similar maturity held, adjusted for a liquidity premium. A higher or lower discount rate would result in a lower or higher fair value asset.

The Partnership’s Suezmax tanker the Toledo Spirit operates pursuant to a time-charter contract that increases or decreases the otherwise fixed-hire rate established in the charter depending on the spot charter rates that the Partnership would have earned had it traded the vessel in the spot tanker market. The time-charter contract endsended in August 2025, althoughJanuary 2019 upon the charterer, haswhich was also the right to terminateowner, selling the time-charter contract in July 2018.vessel (see Note 20a). In order to reduce the variability of its revenue under the Toledo Spirit time-charter, the Partnership entered into an agreement with Teekay Corporation under which Teekay Corporation payspaid the Partnership any amounts payable to the charterer of the Toledo Spirit as a result of spot rates being below the fixed rate, and the Partnership payspaid Teekay Corporation any amounts payable to the Partnership by the

charterer of the Toledo Spirit as a result of spot rates being in excess of the fixed rate. The estimated fair value of this other derivative iswas based in part upon the Partnership’s projection of future spot market tanker rates, which has beenwas derived from current spot market tanker rates and long-term historical average rates as well as an estimated discount rate. The estimated fair value of this other derivative as of December 31, 2017 is2018 was based upon an average daily tanker rate of $17,500$24,000 (December 31, 20162017$22,875)$17,500) over the remaining duration of the charter contract, and assumes the charterer of this vessel will cancel its charter contract in 2018 (see Note 5),which ended January 2019, and a discount rate of 8.7%9.5% (December 31, 201620178.4%8.7%). In developing and evaluating this estimate, the Partnership considersconsidered the current tanker market fundamentals as well as the short and long-term outlook.outlook at that time. A higher or lower average daily tanker rate would result in a higher or lower fair value liability or a lower or higher fair value asset. A higher or lower discount rate would result in a lower or higher fair value asset or liability.

4.Segment Reporting

Prior to 2018, the Partnership reported its financial results on the basis of two business segments: a liquefied gas segment and a conventional tanker segment. During 2018, the Partnership’s Teekay Multi-Gas Pool commenced operations. As part of this initiative, the Partnership completed an internal reorganization and revised its reportable segments, as such changes resulted in management viewing the gas fleet and its components differently. As a result, the Partnership’s LPG and multi-gas carriers are reported in a separate segment apart from its LNG carriers. All segment information for comparative periods has been retroactively adjusted to conform with the change in segment presentation adopted in 2018.

The Partnership has twothree reportable segments, its liquefied gasLNG segment, LPG segment and its conventional tanker segment. The Partnership’s liquefied gasLNG segment consists of LNG carriers LPG carriers and multigas carriers, which can carry both LNG and LPG, which generally operate under long-term, fixed-rate charters to international energy companiescompanies. The Partnership's LPG segment consists of LPG and to Teekay Corporation (see Note 11a).multi-gas carriers which generally operate under voyage charters or time-charters. As at December 31, 2017,2018, the Partnership’s liquefied gasLNG segment consisted of 5049 LNG carriers and LNG carrier newbuildings (including 2625 LNG carriers and LNG carrier newbuildings included in joint ventures that are accounted for under the equity method), and 30. As at December 31, 2018, the Partnership's LPG segment consisted of 29 LPG/Multigasmulti-gas carriers and LPG carrier newbuildings (including 2322 LPG carriers and LPG carrier newbuildings included in a joint venture that is accounted for under the equity method). As at December 31, 2017,2018, the Partnership’s conventional tanker segment consisted of fourone Suezmax-class crude oil tankers and one Handymax product tanker. Segment results are evaluated based on income from vessel operations. The accounting policies applied to the reportable segments are the same as those used in the preparation of the Partnership’s consolidated financial statements.

The following table presents voyage revenues and percentage of consolidated voyage revenues for the Partnership’s customers who accounted for 10% or more of the Partnership's consolidated voyage revenues during any of the periods presented.

LNG Carriers. As at December 31, 2017,2018, the Partnership was a party to capital leases on fiveeight LNG carriers, the Creole Spirit, the Oak Spirit, the Torben Spirit, the Macoma,and the Murex,the Magdala, the Myrina andthe Megara. Upon delivery of the Creole Spirit inthese eight LNG carriers between February 2016 the Oak Spirit inand July 2016, the Torben Spirit in March 2017, the Macoma in October 2017, andthe Murex in November 2017,2018, the Partnership sold these vessels to third parties (or Lessors) and leased them back under 10-year bareboat charter contracts ending in 2026 and 2027. Four of the bareboat charter contracts are fixed-rate capital leases and one is a variable-rate capital lease, and all with a fixed-price purchase obligation at the end of the lease terms.through to 2028. At inception of these leases, the weighted-average interest rate implicit in these leases was 5.2%5.1%.

In addition, as at December 31, 2017, the Partnership had sale-leaseback agreements in place The bareboat charter contracts are accounted for three LNG carrier newbuildings scheduled to deliver during 2018, and at such dates, the buyers will take delivery and charter each respective vessel back to the Partnership. As at December 31, 2017, the Partnership had received $193 million from the buyers, which has been recorded as current and long-term obligations related to capital leases inand have purchase obligations at the Partnership's consolidated balance sheets, and the Partnership has secured a further $375 million in capital lease financing to be received in 2018 upon deliveryend of the vessels.lease terms.

The Partnership understands that these vessels and lease operations are the only assets and operations of the Lessors. The Partnership operates the vessels during the lease term and as a result, is considered to be, under GAAP, the Lessor's primary beneficiary; therefore, the Partnership consolidates the Lessors for financial reporting purposes as VIEs.

The liabilities of the Lessors are loans and are non-recourse to the Partnership. The amounts funded to the Lessors in order to purchase the vessels materially match the funding to be paid by the Partnership's subsidiaries under the sale-leaseback transaction. As a result, the amounts

due by the Partnership's subsidiaries to the Lessors have been included in obligations related to capital leases as representing the Lessors' loans.

The Partnership guarantees the obligations of the Partnership under the bareboat charter contracts.contracts are guaranteed by the Partnership. In addition, the guarantee agreements require the Partnership to maintain minimum levels of tangible net worth and aggregate liquidity, and not to exceed a maximum amount of leverage. As at December 31, 2017,2018, the Partnership was in compliance with all covenants in respect of the obligations related to its capital leases.

As at December 31, 2017,2018, the remaining commitments related to the eight capital leases for the Partnership's LNG carriers, and LNG carrier newbuildings, including the related purchase obligations, approximated $1.4$1.7 billion, including imputed interest of $429.9$435.3 million, repayable from 20182019 through 2027,2028, as indicated below:

Suezmax Tankers.Tanker. As at December 31, 2017,2018, the Partnership was a party, as lessee, to a capital leaseslease on twoone Suezmax tankers, the Teide Spirit andtanker, the Toledo Spirit. Under thesethis capital leases,lease, the owner hashad the option to require the Partnership to purchase the two vessels.vessel. The charterer, Compania Espanole de Petroles, S.A. (or CEPSA), who is also the owner, also hashad the option to cancel the charter contractscontract and the cancellation options areoption was first exercisable in February 2018 and July 2018, respectively.

The Partnership assumes CEPSA will not exercise its options to requireAugust 2018. In January 2019, the Partnership to purchase eithercharterer of the two remaining vessels from CEPSA, but rather it assumes CEPSA will cancel the charter contracts when the cancellation right is first exercisable (in February 2018 and July 2018, respectively) and sell the vessels to third parties, upon which the remaining lease obligations will be extinguished. In December 2017, CEPSA agreed to sell the TeideToledo Spirit to a third party (see Note 19e). Atsold the inception of these leases,vessel and the weighted-average interest rate implicit in these leasescapital lease was 5.5%. These capital leases are variable-rate capital leases. However, any change in the lease payments resulting from changes in interest rates is offset by a corresponding change in the charter hire payments received by the Partnership.terminated.

As at December 31, 2017,2018, the remaining commitments related to the twoone capital leaseslease for the Suezmax tankers,tanker, including the related purchase obligations, approximated $51.0$24.2 million including imputed interest of $1.1$0.2 million, repayable in 2018.2019. Upon sale of the vessel in January 2019, the Partnership returned the vessel to the owner and the full amount of the associated obligation related to the capital lease was concurrently extinguished.

The Partnership’s capital leaseslease relating to its Suezmax tankers dotanker does not contain financial or restrictive covenants other than those relating to operation and maintenance of the vessels.

b) Operating Lease ObligationsLeases
The minimum estimated charter hire payments for the following two fiscal years, as at December 31, 2018, for the Partnership's chartered-in vessel accounted for as an operating lease were as follows:

(i) As at December 31, 2018, the Partnership was chartering in a vessel at a fixed-rate from its 52%-owned joint venture with Marubeni Corporation (or the Teekay LNG-Marubeni Joint Venture) for a period of two years until September 2020. The Partnership recognizes the expense from this charter on a straight-line basis over the firm period of the charter and is presented as time-charter hire expense in the Partnership's consolidated statements of income.

c) Teekay Tangguh Joint Venture Operating Leases
As at December 31, 2017,2018, the Teekay BLT Corporation (or the Teekay Tangguh Joint Venture), of which the Partnership has a 69% ownership interest and consolidates, was a party to operating leases (or Head Leases) whereby it is leasingleases its two LNG carriers (or the Tangguh LNG Carriers) to a third-party company. The Teekay Tangguh Joint Venture is then leasingleases back the LNG carriers from the same third-party company (or the Subleases). Under the terms of these leases, the third-party company claims tax depreciation on the capital expenditures it incurred to lease the vessels. As is typical in these leasing arrangements, tax and change of law risks are assumed by the Teekay Tangguh Joint Venture. Lease payments under the Subleases are based on certain tax and financial assumptions at the commencement of the leases. If an assumption proves to be incorrect, the lease payments are increased or decreased under the Sublease to maintain the agreed after-tax margin. The Teekay Tangguh Joint Venture’s carrying amounts of this estimated tax indemnification guarantee as at December 31, 2018 and 2017 and 2016 were $7.1$6.6 million and $7.5$7.1 million, respectively, and are included as part of other long-term liabilities in the consolidated balance sheets of the Partnership. The tax indemnification is for the duration of the lease contract with the third party plus the years it would take for the lease payments to be statute barred and ends in 2033. Although there is no maximum potential amount of future payments, the Teekay Tangguh Joint Venture may terminate the lease arrangements on a voluntary basis at any time. If the lease arrangements terminate, the Teekay Tangguh Joint Venture will be required to make termination payments to the third-party company sufficient to repay the third-party company’s investment

in the vessels and to compensate it for the tax effect of the terminations, including recapture of any tax depreciation. The Head Leases and the Subleases have 20-year terms and are classified as operating leases. The Head Leases and the Subleases for the two Tangguh LNG Carriers commenced in November 2008 and March 2009.

As at December 31, 2017,2018, the total estimated future minimum rental payments to be received and paid by the Teekay Tangguh Joint Venture related to the lease contracts are as follows:

Revenue

The Partnership’s primary source of revenue is chartering its vessels to customers. The Partnership utilizes three primary forms of contracts, consisting of time-charter contracts, voyage charter contracts and bareboat charter contracts. The Partnership also generates revenue from construction supervision and crew-training for the vessels under construction in its joint venture with China LNG Shipping (Holdings) Limited (or China LNG), CETS Investment Management (HK) Co. Ltd. and BW Investments Pte. Ltd (or the Pan Union Joint Venture), in which the Partnership's ownership interests range from 20% to 30%, and from the start-up of an LNG receiving and regasification terminal under construction related to its 30%-owned joint venture with National Oil and Gas Authority 30%), Gulf Investment Corporation (24%), and Samsung C&T (16%) (or the Bahrain LNG Joint Venture). Such services may include the procurement of third party goods and services for the asset’s owner.

Time Charters

Pursuant to a time-charter contract, the Partnership charters a vessel to a customer for a fixed period of time, generally one year or more. The performance obligations of a time-charter contract, which include the lease of the vessel to the charterer as well as the operation of the vessel, are satisfied as services are rendered over the duration of such contract, as measured using the time that has elapsed from commencement of performance. In addition, any expenses unique to a particular voyage, including any fuel expenses, port fees, cargo loading and unloading expenses, canal tolls, agency fees and commissions, are the responsibility of the customer, as long as the vessel is not off-hire. Hire is based on a fixed daily hire amount and is typically invoiced monthly in advance for time-charter contracts. However, certain sources of variability exist, including penalties, such as those that relate to periods the vessels are off-hire and where minimum speed and performance metrics are not met. In addition, certain time-charter contracts contain provisions allowing the Partnership to be compensated for increases in the Partnership's costs during the term of the charter. Such provisions may be in the form of annual hire rate adjustments for changes in inflation indices or interest rates or in the form of cost reimbursements for vessel operating expenditures or dry-docking expenditures. Finally, in a small number of charters, the Partnership may earn a profit share consideration, which occurs when actual spot tanker rates earned by the vessel exceed certain thresholds for a period of time. Variable consideration of the Partnership’s contracts is typically recognized in the period in which the changes in facts and circumstances on which the variable lease payments are based occur as either such revenue is allocated and accounted for under lease accounting requirements or alternatively such consideration is allocated to distinct periods within a contract that such variable consideration was incurred in. The Partnership does not engage in any specific tactics to minimize residual value risk.

As at December 31, 2018, a substantial majority of the Partnership’s consolidated vessels operated under time-charter contracts with the Partnership’s customers. Such contracts are scheduled to expire between 2019 and 2038. The time-charter contracts for many of the Partnership's LNG carriers have options whereby the charterer can extend the contract for periods up to a total extension between three and 15 years. In addition, each of the Partnership's time-charter contracts are subject to certain termination and purchase provisions. As at December 31, 2018, the Partnership had $26.4 million of advanced payments recognized as contract liabilities included in unearned revenue (December 31, 2017 – $22.2 million) which are expected to be recognized as voyage revenues in 2019 and are included in unearned revenue on the Partnership's consolidated balance sheets. During the year ended December 31, 2018, the Partnership recognized $22.2 million of revenue that was included in the contract liability balance on transition.


Voyage Charters

Voyage charters are charters for a specific voyage that are usually priced on a current or “spot” market rate. The performance obligations of a voyage charter contract, which typically include the lease of the vessel to the charterer as well as the operation of the vessel, are satisfied as services are rendered over the duration of the voyage, as measured using the time that has elapsed from commencement of performance. In addition, any expenses that are unique to a particular voyage, including any fuel expenses, port fees, cargo loading and unloading expenses, canal tolls, agency fees and commissions, are the responsibility of the vessel owner. The Partnership’s voyage charters will normally contain a lease; however, judgment is necessary to determine this based upon the decision-making rights of the charterer under the contract. Consideration for such contracts is generally fixed, although certain sources of variability exist - for example, delays caused by the charterer result in additional consideration. Payment for the voyage is not due until the voyage is completed. The duration of a single voyage is typically less than three months. The Partnership does not engage in any specific tactics to minimize residual value risk due to the short-term nature of the contracts.

Bareboat Charters

Pursuant to a bareboat charter, the Partnership charters a vessel to a customer for a fixed period of time, generally one year or more, at rates that are generally fixed. However, the customer is responsible for operation and maintenance of the vessel with its own crew as well as any expenses that are unique to a particular voyage, including any fuel expenses, port fees, cargo loading and unloading expenses, canal tolls, agency fees and commissions. If the vessel goes off-hire due to a mechanical issue or any other reason, the monthly hire received by the Partnership is normally not impacted. The performance obligations of a bareboat charter, which include the lease of the vessel to the charterer, are satisfied over the duration of such contract, as measured using the time elapsed from commencement of the lease. Hire is typically invoiced monthly in advance for bareboat charters, based on a fixed daily hire amount.

Net Investments in Direct Financing Leases

The Tangguh LNG Carriers commenced their time-charters with their charterers in 2009. Both time-charter contracts are accounted for as direct financing leases with 20-year terms. In 2013, the Partnership acquired two 155,900-cubic meter LNG carriers (or Awilco LNG Carriers) from Norway-based Awilco LNG ASA (or Awilco) and chartered them back to Awilco on five- and four-year fixed-rate bareboat charter contracts (plus a one-year extension option), respectively, with Awilco holding fixed-price purchase obligations at the end of the charter. The bareboat charters with Awilco were accounted for as direct financing leases. In June 2017, the Partnership agreed to amend the charter contracts with Awilco to defer a portion of charter hire and extend the bareboat charter contracts and related purchase obligations on both vessels to December 2019. The amendments have the effect of deferring charter hire of between $10,600 per day and $20,600 per day per vessel from July 1, 2017 until December 2019, with such deferred amounts added to the purchase obligation amounts. As a result of the contract amendments, oneboth of the charter contracts with Awilco has beenwere reclassified as an operating leaseleases upon the expiry of its original contract terms in November 2017.

As at December 31, 2017,2018, estimated minimum lease payments to be received by the Partnership related to the Tangguh LNG Carrierits direct financing leases in each of the next five succeeding fiscal years are approximately $39.1$64.2 million per year from 2018 through 2022. Both(2019), $64.3 million (2020), $64.2 million (2021), $64.2 million (2022), $64.0 million (2023) and an aggregate of $576.2 million thereafter. The leases are scheduled to end in 2029. In addition, the estimated minimum lease payments to be received by the Partnership in 2018 related to the Awilco LNG Carrier lease, up to its original contract terms in August 2018, were approximately $6.8 million.between 2029 and 2039.
Operating Leases
As at December 31, 2017,2018, the minimum scheduled future rentals to be received by the Partnership in each of the next five years for the lease and non-lease elements related to charters that were accounted for as operating leases are approximately $329.7 million (2018), $309.2$482.7 million (2019), $278.9$438.2 million (2020), $239.4$398.3 million (2021), and $216.4$321.9 million (2022), and $278.1 million (2023). Minimum scheduled future rentals on operating lease contracts do not include rentals generated from new contracts entered into after December 31, 2017,2018, rentals from vessels in the Partnership’s equity-accounted investments, rentals from unexercised option periods of contracts that existed on December 31, 2017,2018, variable or contingent rentals, or rentals from contracts which commenced after December 31, 2017.2018. Therefore, the minimum scheduled future rentals on operating leases should not be construed to reflect total charter hire revenues for any of these five years.

The carrying amount of the Partnership's vessels which are employed on these charter contracts as at December 31, 2018, was $3.1 billion (December 31, 2017 – $2.2 billion). The cost and accumulated depreciation of these vessels employed on these charter contracts as at December 31, 2018 were $3.8 billion (December 31, 2017 – $2.9 billion) and $698.5 million (December 31, 2017 – $646.2 million), respectively.
Contract Costs
In certain cases, the Partnership incurs pre-operational costs that relate directly to a specific customer contract, that generate or enhance resources of the Partnership that will be used in satisfying performance obligations in the future, whereby such costs are expected to be recovered via the customer contract. Those costs include costs incurred to reposition a vessel to a location where a charterer will take delivery of the vessel. In certain cases, the Partnership must make judgments about whether costs relate directly to a specific customer contract or whether costs were factored into the pricing of a customer contract and thus expected to be recovered. Such deferred costs are amortized on a straight-line basis over the duration of the customer contract. Amortization of such costs for the year ended December 31, 2018 was $0.2 million ($nil during 2017 and 2016). As at December 31, 2018, repositioning costs of $3.5 million (December 31, 2017 – $nil) were included as part of other assets in the Partnership's consolidated balance sheets.

(i)Bahrain LNG Joint Venture
On December 2, 2015, the Partnership (30%) entered into a joint venture agreement with National Oil & Gas Authority (or Nogaholding) (30%), Gulf Investment Corporation (or GIC) (24%) and Samsung C&T (or Samsung) (16%) to form a joint venture, Bahrain LNG W.L.L. (or the Bahrain LNG Joint Venture), for the development of an LNG receiving and regasification terminal in Bahrain. The project willis expected to include an offshore LNG receiving jetty and breakwater, an adjacent regasification platform, subsea gas pipelines from the platform to shore, an onshore gas receiving facility, and an onshore nitrogen production facility with a total LNG terminal capacity of 800 million standard cubic feet per day and will be owned and operated under a 20-year agreement, commencingwhich is expected to commence in early-2019.mid-2019. In addition, the Partnership will supply a floating storage unit (or has supplied an FSU) in connection with this project which will be modified from one of the Partnership’s four MEGI LNG carrier newbuildings ordered from Daewoo Shipbuilding & Marine Engineering Co. (or DSME) (see Note 13a),commencing in September 2018 through a 20-year21-year time-charter contract with the Bahrain LNG Joint Venture.
As at December 31, 2017,2018, the Partnership had advanced $79.1 million (December 31, 20162017$62.9$79.1 million) to the Bahrain LNG Joint Venture. These advances bear interest at LIBOR plus 1.25% and as at December 31, 2017,2018, the interest accruedreceivable on these advances was $0.1 million$nil (December 31, 20162017 – $0.1 million). These amounts are included in the table above.
(ii)Yamal LNG Joint Venture
The Partnership has a 50/50 joint venture agreement with China LNG Shipping (Holdings) Limited (or the Yamal LNG Joint Venture) and the joint venture hashad ordered six internationally-flagged icebreaker LNG carriers for a project located on the Yamal Peninsula in Northern Russia (or the Yamal LNG Project). of which two LNG carrier newbuildings were delivered during 2018.
During the year ended, December 31, 2017, the Yamal LNG Joint Venture converted the $195 million advances from each joint venture partner, including accrued interest, into contributed capital of the joint venture. As at December 31, 2016, the Partnership had advanced $146.7 million to the Yamal LNG Joint Venture and the interest accrued on these advances was $9.4 million. Both the contributed capital and the advances are included in the table above. In December 2017, the Yamal LNG Joint Venture secured a $1.6 billion long-term debt facility to finance all six of its ARC7 LNG carrier newbuildings. As part of the completed financing, the Yamal LNG Joint Venture returned a total of $104 million of capital back to the joint venture partners in December 2017, of which the Partnership’s share was $52 million. The Partnership has guaranteed its 50% share of an $816 milliona secured loan facility in the Yamal LNG Joint Venture and, as a result, has recorded a guarantee liability. The carrying value of the guarantee liability as at December 31, 20172018 was $0.6 million (December 31, 20162017$nil)$0.6 million) and is included as part of other long-term liabilities in the Partnership’s consolidated balance sheets.
(iii)Pan Union Joint Venture
In June 2014, the Partnership acquired from Shell its ownership interests in four LNG carrier newbuildings. As compensation for Shell’s ownership interests in these four LNG carrier newbuildings, the Partnership assumed Shell’s obligation to provide the shipbuilding supervision and crew training services for the four LNG carrier newbuildings up to their delivery date pursuant to a ship construction support agreement. The Partnership initially estimated it would incur approximately $36.9 million of costs to provide these services, of which Shell has agreed to pay a fixed amount of $20.3 million. The Partnership estimated that the fair value of the service obligation was $33.3 million and the fair value of the amount due from Shell was $16.5 million. As at December 31, 2017,

2018, the carrying value of the service obligation of $8.2 million$nil (December 31, 20162017$22.6$8.2 million) is included in both the current portion of in-process contracts and in-process contracts and the carrying value of the receivable from Shell of $3.5$0.2 million (December 31, 20162017$10.9$3.5 million) is included in accounts receivable and other assets in the Partnership’s consolidated balance sheets.
As at December 31, 2017,2018, the Partnership has a 30% ownership interest in two LNG carriers, the Pan Asia and the Pan Americas, and a 20% ownership interest in one LNG carrier, the Pan AsiaEurope, , and one LNG carrier newbuilding and a 20% ownership interest in the remaining two LNG carrier newbuildings (or(or collectively, the Pan Union Joint Venture). The Pan AsiaAfrica was delivered on October 13, 2017January 8, 2019 and concurrently commenced its 20-year charter contract with Shell.
On initial acquisition, the basis difference between the Partnership's investment and the carrying value of the Pan Union Joint Venture's net assets was substantially attributed to ship construction support agreements and the time-charter contracts. At December 31, 2017,2018, the unamortized amount of the basis difference was $11.4$11.0 million (December 31, 20162017 - $16.8$11.4 million).
(iv)Exmar LPG Joint Venture
The Partnership has a 50/50 LPG-related joint venture agreement with Exmar NV (or Exmar) (or the Exmar LPG Joint Venture). The Partnership has guaranteed its 50% share of a secured loan facility and four capital leases in the Exmar LPG Joint Venture and, as a result, has recorded a guarantee liability. The carrying value of the guarantee liability as at December 31, 20172018 was $1.6$1.3 million (December 31, 20162017$1.3$1.6 million) and is included as part of other long-term liabilities in the Partnership’s consolidated balance sheets.

As at December 31, 2017,2018, the Partnership had advanced $52.3 million (December 31, 20162017 – $52.3 million) to the Exmar LPG Joint Venture, which bears interest at LIBOR plus 0.50% and has no fixed repayment terms. As at December 31, 2017,2018, the interest accruedreceivable on these advances was $0.2 million$nil (December 31, 20162017$1.1$0.2 million). These amounts are included in the table above.
On initial acquisition, the basis difference between the Partnership's investment and the carrying value of the Exmar LPG Joint Venture's net assets was substantially attributed to the value of the vessels and charter agreements of the Exmar LPG Joint Venture and goodwill in accordance with the finalized purchase price allocation. At December 31, 2017,2018, the unamortized amount of the basis difference was $25.5$24.9 million (December 31, 20162017$30.2$25.5 million).
(v)Teekay LNG-Marubeni Joint Venture
The Partnership has a joint venture agreement with Marubeni Corporation (or the Teekay LNG-Marubeni Joint Venture). Since control of the Teekay LNG-Marubeni Joint Venture is shared jointly between Marubeni and the Partnership, the Partnership accounts for its investment in the Teekay LNG-Marubeni Joint Venture using the equity method. In March 2017,September 2018, the Teekay LNG-Marubeni Joint Venture completed the refinancing of one of its previous $396 million debt facilityfacilities maturing in 2019 by entering into a new $335$306.5 million U.S. Dollar-denominated term loan maturing in September 2019.

All Euro-denominated term loans and NOK-denominated bonds are revalued at the end of each period using the then-prevailing U.S. Dollar exchange rate. Due primarily to the revaluation of the Partnership’s NOK-denominated bonds, the Partnership’s Euro-denominated term loans and restricted cash, the repayment of the Partnership's NOK-denominated bonds and the termination of the associated cross-currencycross currency swaps, and the change in the valuation of the Partnership’s cross-currencycross currency swaps, the Partnership incurred foreign exchange gains (losses) gains of $1.4 million, $(26.9) million, $5.3 million, and $13.9$5.3 million for the years ended December 31, 2018, 2017 2016 and 2015,2016, respectively.

The aggregate annual long-term debt principal repayments required subsequent to December 31, 2017, after giving effect to the revolving credit facility refinancing completed in February 2018 are $555.4 million (2018), $83.9$136.6 million (2019), $359.5$613.0 million (2020), $346.7$404.1 million (2021), $144.8$92.1 million (2022), $213.3 million (2023) and $320.1$528.5 million (thereafter).

As at December 31, 2017,2018, the Partnership had twohas three facilities with an aggregate outstanding loan balance of $90.6$442.2 million that require it to maintain minimum vessel-value-to-outstanding-loan-principal-balance ratios ranging from 110%115% to 135%, which as at December 31, 20172018 ranged from 126%132% to 243%.198% which exceeded the required ratios for the three facilities. The vessel values were determined usingused in calculating these ratios are the appraised values provided by third parties where available or prepared by the Partnership based on second-hand sale and purchase market comparables or using a depreciated replacement cost approach.data. Since vessel values can be volatile, the Partnership’s estimates of market value may not be indicative of either the current or future prices that could be obtained if the Partnership sold any of the vessels. The Partnership’s ship-owning subsidiaries may not, among other things, pay dividends or distributions if the Partnership's subsidiaries are in default under their term loans or revolving credit facilities.facilities and, in addition, one of the term loans in the Teekay Nakilat Joint Venture requires it to satisfy a minimum vessel value to outstanding loan principal balance ratio to pay dividends.

12.13.Derivative Instruments and Hedging Activities
The Partnership uses derivative instruments in accordance with its overall risk management policy.
Foreign Exchange Risk
The Partnership entered into cross-currencycross currency swaps concurrently with the issuance of its NOK-denominated senior unsecured bonds (see Note 9)10), and pursuant to these swaps, the Partnership receives the principal amount in NOK on maturity dates of the swaps in exchange for payments of a fixed U.S. Dollar amount. In addition, the cross-currencycross currency swaps exchange a receipt of floating interest in NOK based on NIBOR plus a margin for a payment of U.S. Dollar fixed interest. The purpose of the cross-currencycross currency swaps is to economically hedge the foreign currency exposure on the payment of interest and principal of the Partnership’s NOK-denominated bonds due in 2018, 2020, 2021 and 2021,2023, and to economically hedge the interest rate exposure. The following table reflects information relating to the cross-currencycross currency swaps as at December 31, 2017.2018.

Credit Risk
The Partnership is exposed to credit loss in the event of non-performance by the counterparties to the interest rate swap agreements. In order to minimize counterparty risk, the Partnership only enters into derivative transactions with counterparties that are rated A- or better by Standard & Poor’s or A3 or better by Moody’s at the time of the transactions. In addition, to the extent practical, interest rate swaps are entered into with different counterparties to reduce concentration risk.
Other Derivatives
In order to reduce the variability of its revenue, the Partnership has entered into an agreement with Teekay Corporation under which Teekay Corporation pays the Partnership any amounts payable to the charterer of the Toledo Spirit as a result of spot rates being below the fixed rate, and the Partnership pays Teekay Corporation any amounts payable to the Partnership by the charterer of the Toledo Spirit as a result of spot rates being in excess of the fixed rate. The fair value of the derivative asset at December 31, 20172018 was $1.6$1.1 million (December 31, 20162017 – an asset of $2.1$1.6 million).

(v)(iv)The Partnership has a 30% ownership interest in the Bahrain LNG Joint Venture for the development of an LNG receiving and regasification terminal in Bahrain. The project will include an FSU, which will be modified from one of the Partnership’s existing MEGI LNG carrier newbuildings, an offshore gas receiving facility, and an onshore nitrogen production facility. The terminal will have a capacity of 800 million standard cubic feet per day and will be owned and operated under a 20-year agreement commencing early-2019.mid-2019. The receiving and regasification terminal is expected to have a fully-built up cost of approximately $960.0$903 million. The Bahrain LNG Joint Venture has secured undrawn debt financing of $134$195 million, relatedof which $58 million relates to the Partnership's proportionate share of the commitments included in the table above.
(vi)The Partnership has a 50% ownership interest in the Exmar LPG Joint Venture which has three LPG carrier newbuildings scheduled for delivery in 2018 and has secured $56 million of financing for two of the three LPG carrier newbuildings related to the Partnership's proportionate share of the commitments included in the table above.

b)Management is required to assess if
Following the Partnership will have sufficient liquidity to continue as a going concerntermination of the capital lease arrangements for the one-year periodthree LNG carriers in the Teekay Nakilat Joint Venturein 2014, the lessor made a determination that additional rentals were due under the leases following a challenge by the issuanceUK taxing authority. As a result, in 2018 the Teekay Nakilat Joint Venture recognized an additional liability of its financial statements. The Partnership anticipates$53.0 million, which was included as part of other (expense) income in the Partnership's consolidated statements of income, and paid this liability by releasing a $7.0 million cash deposit it had made with the lessor and making a $56.0 million cash payment for the balance, which was based on the GBP/USD foreign currency exchange rates at the time the payments related to commitments to fund its wholly-owned vessels under construction of $552.4 million during 2018 and $252.1 million during 2019, as well as other payments relating to its joint ventures (see Note 13a).were made.

Over the one-year period following the issuance of these consolidated financial statements, the Partnership will need to obtain additional sources of financing, in addition to amounts generated from operations, to fund scheduled debt repayments and construction commitments and to meet its minimum liquidity requirements under its financial covenants. These anticipated sources of financing include refinancing loan facilities maturing in 2018 (see Note 19f) as well as obtaining new debt financing for the unfinanced portion of the Partnership's vessels under construction.
The Partnership is actively pursuing the alternatives described above, which it considers probable of completion based on the Partnership’s history of being able to refinance similar loan facilities and to obtain new debt financing for its vessels under construction, as well as the progress it has made on the financing process to-date. The Partnership is in various stages of completion with respect to its anticipated new financing facilities.
Based on the Partnership’s liquidity at the date these consolidated financial statements were issued, the liquidity it expects to generate from operations over the following year, and by incorporating the Partnership’s plans to raise additional liquidity that it considers probable of completion, the Partnership estimates that it will have sufficient liquidity to continue as a going concern for at least the one-year period following the issuance of these consolidated financial statements.
c)
The Partnership owns a 70% ownership interest in the Teekay Nakilat Joint Venture, which was the lessee under three separate 30-year capital lease arrangements with a third party for three LNG carriers (or the RasGas II LNG Carriers). Under the terms of the leasing arrangements for the RasGas II LNG Carriers, the lessor claimed tax depreciation on the capital expenditures it incurred to acquire these vessels. As is typical in these leasing arrangements, tax and change of law risks were assumed by the lessee, in this case the Teekay Nakilat Joint Venture. Lease payments under the lease arrangements were based on certain tax and financial assumptions at the commencement of the leases and subsequently adjusted to maintain the lessor’s agreed after-tax margin. On December 22, 2014, the Teekay Nakilat Joint Venture terminated the leasing of the RasGas II LNG Carriers. However, the Teekay Nakilat Joint Venture remains obligated to the lessor to maintain the lessor’s agreed after-tax margin from the commencement of the lease to the lease termination date and as at December 31, 2017, the Teekay Nakilat Joint Venture’s carrying amount of this estimated tax indemnification guarantee was $12.7 million (December 31, 2016 – $13.3 million) which is included as part of other long-term liabilities in the consolidated balance sheets of the Partnership.  Additionally, as at December 31, 2017, the Teekay Nakilat Joint Venture had $7.0 million (December 31, 2016 – $6.8 million) on deposit with the lessor as security against any future claims and recorded as part of restricted cash - long-term in the Partnership’s consolidated balance sheets.

The UK taxing authority (or HMRC) has been challenging the use of similar lease structures in the UK courts. One of those challenges was eventually decided in favor of HMRC (Lloyds Bank Equipment Leasing No. 1 or LEL1), with the lessor and lessee choosing not to appeal further. The LEL1 tax case concluded that capital allowances were not available to the lessor. On the basis of this conclusion, HMRC is now asking lessees on other leases, including the Teekay Nakilat Joint Venture, to accept that capital allowances are not available to their lessor. The Teekay Nakilat Joint Venture does not accept this contention and has informed HMRC of this position. It is not known at this time whether the Teekay Nakilat Joint Venture would eventually prevail in court. If the former lessor of the RasGas II LNG Carriers were to lose on a similar claim from HMRC, the Partnership’s 70% share of Teekay Nakilat Joint Venture's potential exposure is estimated to be approximately $44 million. Such estimate is primarily based on information received from the lessor.
d)The Partnership owns a 69% ownership interest in the Teekay Tangguh Joint Venture which is currently in discussions with HMRCundergoing a tax audit related to its tax returns filed for the 2010 and subsequent fiscal year. HMRCyears. The UK taxing authority has challenged the deductibility of certain transactions not directly related party transactionsto the long funding lease and the Teekay Tangguh Joint Venture has submittedrecorded a settlement proposalprovision of $1.6 million (of which the Partnership’s 69% share is $1.1 million) to HMRC

in December 2017 which is included in income tax expense in the Partnership’s consolidated statements of income for the year ended December 31, 2017.

e)d)In May 2016, the Teekay LNG-Marubeni Joint Venture reached a settlement agreement with a charterer relating to a disputed charter contract termination for one of its LNG carriers that occurred in 2015. The charterer paid $39.0 million to the Teekay LNG-Marubeni Joint Venture in June 2016 for lost revenues, of which the Partnership’s share of $20.3 million was recorded in equity income for the year ended December 31, 2016.

e)Management is required to assess whether the Partnership will have sufficient liquidity to continue as a going concern for the one-year period following the issuance of its financial statements. The Partnership completed a number of financings and re-financings over the past 12 months, including the Partnership's refinancing and up-sizing of its $190 million revolving credit facility with a new $225 million revolving credit facility in early-November 2018 and the Partnership securing $159 million financing on its one remaining LNG carrier newbuilding in our consolidated fleet in January 2019. Based on the Partnership’s liquidity at the date these consolidated financial statements were issued and the liquidity it expects to generate from operations over the following year, the Partnership estimates that it will have sufficient liquidity to continue as a going concern for at least the one-year period following the issuance of these consolidated financial statements.

15.16.Total Capital and Net Income Per Common Unit
As at December 31, 2017,2018, a total of 68.3%68.2% of the Partnership's common units outstanding were held by the public. The remaining common units, as well as the 2% general partner interest, were held by subsidiaries of Teekay Corporation. All of the Partnership's outstanding Series A Cumulative Redeemable Perpetual Preferred Units (or the Series A Preferred Units) and Series B Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units (or the Series B Preferred Units)Units) are held by the public.
Limited Partners’ Rights
Significant rights of the Partnership’s limited partners include the following:

Right of common unitholders to receive distribution of Available Cash (as defined in the partnership agreement and which takes into account cash reserves for, among other things, future capital expenditures and future credit needs of the Partnership) within approximately 45 days after the end of each quarter.
No limited partner shall have any management power over the Partnership’s business and affairs; the General Partner is responsible for the conduct, directions and management of the Partnership’s activities.
The General Partner may be removed if such removal is approved by common unitholders holding at least 66-2/3% of the outstanding units voting as a single class, including units held by our General Partner and its affiliates.
Incentive Distribution Rights

The General Partner is entitled to incentive distributions if the amount the Partnership distributes to common unitholders with respect to any quarter exceeds specified target levels shown below:

Quarterly Distribution Target Amount (per unit) Unitholders General Partner
Minimum quarterly distribution of $0.4125 98% 2%
Up to $0.4625 98% 2%
Above $0.4625 up to $0.5375 85% 15%
Above $0.5375 up to $0.6500 75% 25%
Above $0.6500 50% 50%

During 2018, 2017, and 2016, the quarterly cash distributions were below $0.4625 per common unit and, consequently, the assumed distribution of net income was based on the limited partners' and General Partner’s ownership percentage for the purposes of the net income per common unit calculation. During 2015, quarterly cash distributions exceeded $0.4625 per common unit and, consequently, the assumed distribution of net income for 2015 resulted in the use of the increasing percentages to calculate the General Partner’s interest in net income for the purposes of the net income per common unit calculation.

In the event of a liquidation, all property and cash in excess of that required to discharge all liabilities and liquidation amounts on the Series A Preferred Units and Series B Preferred Units will be distributed to the common unitholders and the General Partner in proportion to their capital account balances, as adjusted to reflect any gain or loss upon the sale or other disposition of the Partnership’s assets in liquidation in accordance with the partnership agreement.
Net Income Per Common Unit
Limited partners' interest in net income per common unit is determined by dividing net income, after deducting the amount of net income attributable to the non-controlling interests, the General Partner’s interest and the distributions on the Series A and Series B Preferred Units by the weighted-average number of common units outstanding during the period. The distributions payable on the Series A and Series B Preferred Units (which were issued on October 5, 2016) for the year ended December 31, 20172018 were $11.3$25.7 million (December 31, 2017 – $14.0 million, December 31, 2016 – $2.7 million, December 31, 2015 – $nil)million). The distributions payable on the Series B Preferred Units (which were issued on October 23, 2017) for the year ended December 31, 2017 were $2.7 million (December 31, 2016 and December 31, 2015 – $nil).

The General Partner’s and common unitholders’ interests in net income are calculated as if all net income was distributed according to the terms of the Partnership’s partnership agreement, regardless of whether those earnings would or could be distributed. The partnership agreement does not provide for the distribution of net income; rather, it provides for the distribution of available cash, which is a contractually defined term that generally means all cash on hand at the end of each quarter after establishment of cash reserves determined by the Partnership’s boardBoard of directorsDirectors to provide for the proper conduct of the Partnership’s business, including reserves for maintenance and replacement capital expenditure and anticipated credit needs. In addition, the General Partner is entitled to incentive distributions if the amount the Partnership distributes to common unitholders with respect to any quarter exceeds specified target levels. Unlike available cash, net income is affected by non-cash items, such as depreciation and amortization, unrealized gains or losses on non-designated derivative instruments and foreign currency translation gains (losses).

Pursuant to the Partnership agreement, allocations to partners are made on a quarterly basis.

The awards were fully vested in March 20162017 and March 2015,2016, respectively. The compensation to the non-management directors is included in general and administrative expenses on the Partnership’s consolidated statements of income.

The Partnership grants restricted unit awards as incentive-based compensation under the Teekay LNG Partners L.P. 2005 Long-Term Incentive Plan to certain of the Partnership’s employees and to certain employees of Teekay Corporation’s subsidiaries that provide services to the Partnership. The Partnership measures the cost of such awards using the grant date fair value of the award and recognizes that cost, net of estimated forfeitures, over the requisite service period. The requisite service period consists of the period from the grant date of the award to the earlier of the date of vesting or the date the recipient becomes eligible for retirement. For unit-based compensation awards subject to graded vesting, the Partnership calculates the value for the award as if it was one single award with one expected life and amortizes the calculated expense for the entire award on a straight-line basis over the requisite service period. The compensation cost of the Partnership’s unit-based compensation awards is reflected in general and administrative expenses in the Partnership’s consolidated statements of income.

Each restricted unit is equal in value to one of the Partnership's common units plus reinvested distributions from the grant date to the vesting date. The restricted units vest equally over three years from the grant date. Any portion of a restricted unit award that is not vested on the date of a recipient’s termination of service is canceled, unless their termination arises as a result of the recipient’s retirement, and in this case, the restricted unit award will continue to vest in accordance with the vesting schedule. Upon vesting, the value of the restricted unit awards is paid to each recipient in the form of common units, net of withholding tax. During the years ended December 31, 2018, 2017 2016 and 2015,2016, the Partnership recorded an expense of $1.3 million, $1.0 million, $1.3 million, and $1.2$1.3 million, respectively, related to the restricted units and common units.
