Accounting Policies [Abstract]
Summary of Significant Accounting Policies	1. Summary of Significant Accounting Policies Basis of Presentation The consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (or GAAP Partnership Significant intercompany balances and transactions have been eliminated upon consolidation. In addition, certain of the comparative figures as at December 31, 2014 have been reclassified to conform to the presentation adopted in the current period relating to debt issuance costs. As part of the adoption of Accounting Standards Update 2015-03, Simplifying the Presentation of Debt Issuance Costs ASU 2015-03 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 separately in the accompanying consolidated statements of income. Operating revenues and expenses The lease element of 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 as the applicable vessel operates under the charter. The lease element of the Partnership’s time-charters that are accounted for as direct financing leases are reflected on the balance sheets as net investments in direct financing leases. The lease element is recognized over the lease term using the effective interest rate method and is included in voyage revenues. The Partnership recognizes revenues from the non-lease element of time-charter contracts as services are performed. The Partnership does not recognize revenues during days that the vessel is off-hire. Voyage expenses are all expenses unique to a particular voyage, including bunker fuel expenses, port fees, cargo loading and unloading expenses, canal tolls, agency fees and commissions. 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. Cash and cash equivalents The Partnership classifies all highly-liquid investments with a maturity date of three months or less when purchased as cash and cash equivalents. 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. 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. 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 LNG Vessel capital modifications include the addition of new equipment or can encompass various modifications to the vessel which are aimed at improving or increasing the operational efficiency and functionality of the asset. This type of expenditure is amortized over the estimated useful life of the modification. Expenditures covering recurring routine repairs and maintenance are expensed as incurred. Interest costs capitalized to vessels and equipment for the years ended December 31, 2015, 2014 and 2013 aggregated $8.2 million, $3.1 million and $1.3 million, respectively. Gains on vessels sold and leased back under capital leases are deferred and amortized over the remaining estimated useful life of the vessel. Losses on vessels sold and leased back under capital leases are recognized immediately to the extent that the fair value of the vessel at the time of sale-leaseback is less than its book value. Generally, the Partnership dry docks each of its vessels every 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 period. 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 over the estimated useful life of the dry dock. The Partnership includes in capitalized dry docking those costs incurred as part of the dry docking to meet 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. 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. The following table summarizes the change in the Partnership’s capitalized dry docking costs, from January 1, 2013 to December 31, 2015: Year Ended December 31, 2015 $ 2014 $ 2013 $ Balance at January 1, 33,635 40,328 28,821 Cost incurred for dry docking 10,357 13,471 27,203 Sales of vessels (note 15e) — (5,327 ) (2,285 ) Dry-dock amortization (10,076 ) (14,837 ) (13,411 ) Balance at December 31, 33,916 33,635 40,328 Vessels and equipment that are “held and used” 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 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 hand sale and purchase market exists, 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. Investments in and advances to equity accounted joint ventures The Partnership’s investments in certain joint ventures 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 ventures 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 the estimated fair value is less than the 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. Debt issuance costs Debt issuance costs, including fees, commissions and legal expenses, are presented as a direct reduction from the carrying amount of the debt liability and are amortized on an effective interest rate method over the term of the relevant loan. Amortization of debt issuance costs is included in interest expense. Goodwill and intangible assets Goodwill is not amortized, but 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. 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. 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 and 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 sheet and subsequently remeasured to fair value, 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. At December 31, 2015, the Partnership has not applied hedge accounting to its derivative instruments, except for several interest rate swaps in its equity accounted joint ventures (see note 6). 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 possible 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 in the consolidated statements of income. The ineffective portion of the change in fair value of the derivative financial instruments is immediately recognized in earnings in the consolidated statements of income. If a cash flow hedge is terminated and the originally hedged item is still considered possible 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 consolidated statements of income. If the hedged items are no longer possible of occurring, amounts recognized in total equity are immediately transferred to the earnings item in the 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 ASC Derivatives and Hedging Toledo Spirit 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. 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 are 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 two of the Partnership’s Spanish-flagged vessels are subject to the Spanish Tonnage Tax Regime (or TTR The Partnership recognizes the benefits of uncertain tax positions when 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, including resolution of any related appeals or litigation processes, based on the technical merits of the position. If a tax position meets the more-likely-than-not recognition threshold, it is measured to determine the amount of benefit to recognize in the financial statements. 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 (expense) on the Partnership’s consolidated statements of income as the Partnership’s risk from the guarantees declines 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.

Accounting Pronouncements In April 2014, the FASB issued Accounting Standards Update 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity ASU 2014-08 In May 2014, the FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers ASU 2014-09 In February 2015, the FASB issued Accounting Standards Update 2015-02, Amendments to the Consolidation Analysis ASU 2015-02 In April 2015, the FASB issued ASU 2015-03. The Partnership adopted ASU 2015-03 effective December 31, 2015. Prior period information has been retrospectively adjusted. Prior to the adoption of ASU 2015-03, all debt issuance costs were presented as other non-current assets in the Partnership’s consolidated balance sheets. With the adoption of ASU 2015-03 the Partnership presents those debt issuance costs related to a recognized debt liability as a direct deduction from the carrying amount of that debt liability in the Partnership’s consolidated balance sheets. Debt issuance costs related to loan facilities without a recognized debt liability will continue to be presented as non-current assets in the Partnership’s consolidated balance sheets. As a result of adopting ASU 2015-03, non-current assets and total assets have decreased by $16.3 million (December 31, 2015) and $17.1 million (December 31, 2014), current portion of long-term debt and current liabilities has decreased by $1.1 million (December 31, 2015) and $0.1 million (December 31, 2014), long-term debt has decreased by $15.2 million (December 31, 2015) and $17.0 million (December 31, 2014), and total liabilities has decreased by $16.3 million (December 31, 2015) and $17.1 million (December 31, 2014). Such changes have also impacted the Partnership’s reconciliation of segment assets to total assets (see Note 4) and the carrying value of long-term debt (see Note 10). In addition, the Partnership’s equity accounted investments have adopted ASU 2015-03 effective December 31, 2015. As a result, the Partnership’s condensed summary of its equity accounted investments in Note 6 has been impacted. More specifically, other assets - non-current has decreased by $60.8 million (December 31, 2015) and $17.8 million (December 31, 2014), vessels and equipment has decreased by $15.8 million (December 31, 2014), net investments in direct financing leases – non-current has decreased by $23.5 million (December 31, 2014), current portion of long-term debt and obligations under capital lease has decreased by $5.0 million (December 31, 2015) and $5.0 million (December 31, 2014), and long-term debt and obligations under capital lease has decreased by $55.8 million (December 31, 2015) and $52.1 million (December 31, 2014).

Financial Instruments	3. Financial Instruments 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 Interest rate swap/swaption and cross-currency swap agreements Other derivative Toledo Spirit Long-term receivable included accounts receivable and other assets Long-term debt 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.

Segment Reporting [Abstract]
Segment Reporting	4. Segment Reporting The Partnership has two reportable segments, its liquefied gas segment and its conventional tanker segment. The Partnership’s liquefied gas 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 companies and Teekay Corporation (see Note 12a). As at December 31, 2015, the Partnership’s liquefied gas segment consisted of 50 LNG carriers (including 26 LNG carriers included in joint ventures that are accounted for under the equity method), and 29 LPG/Multigas carriers (including 23 LPG carriers included in a joint venture that is accounted for under the equity method). As at December 31, 2015, the Partnership’s conventional tanker segment consisted of seven Suezmax-class crude oil tankers and one Handymax product tanker which generally operate under long-term, fixed-rate time-charter contracts to international energy and shipping companies. 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 top customers during any of the periods presented.

The amounts in the table below assume the owner will not exercise its options to require the Partnership to purchase either of the two remaining vessels from the owner, but rather it assumes the owner will cancel the charter contracts when the cancellation right is first exercisable (in October 2017 and July 2018, respectively), and sell the vessel to a third party, upon which the remaining lease obligation will be extinguished. At the inception of these leases, the weighted-average interest rate implicit in these leases 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. As at December 31, 2015, the remaining commitments under the two capital leases, including the purchase obligations for the two Suezmax tankers, approximated $65.9 million, including imputed interest of $6.8 million, repayable from 2016 through 2018, as indicated below: Year Commitment 2016 $ 7,673 2017 $ 30,953 2018 $ 27,296 The Partnership’s capital leases do not contain financial or restrictive covenants other than those relating to operation and maintenance of the vessels. Restricted Cash The Partnership maintains restricted cash deposits relating to certain term loans, collateral for cross-currency swaps, project tenders, leasing arrangements (see Note 14c) and amounts received from charterers to be used only for dry-docking expenditures and emergency repairs, which cash totaled $111.5 million and $46.0 million as at December 31, 2015 and 2014, respectively. Operating Lease Obligations Teekay Tangguh Joint Venture As at December 31, 2015, the Teekay BLT Corporation (or the Teekay Tangguh Joint Venture Head Leases Tangguh LNG Carriers Subleases As at December 31, 2015, the total estimated future minimum rental payments to be received and paid under the lease contracts are as follows: Year Head Lease Receipts (i) Sublease Payments (i)(ii) 2016 $ 21,242 $ 24,113 2017 $ 21,242 $ 24,113 2018 $ 21,242 $ 24,113 2019 $ 21,242 $ 24,113 2020 $ 21,242 $ 24,113 Thereafter $ 175,337 $ 199,072 Total $ 281,547 $ 319,637 (i) The Head Leases are fixed-rate operating leases while the Subleases have a small variable-rate component. As at December 31, 2015, the Partnership had received $228.8 million of aggregate Head Lease receipts and had paid $163.7 million of aggregate Sublease payments. The portion of the Head Lease receipts that have not been recognized into earnings are deferred and amortized on a straight line basis over the lease terms and, as at December 31, 2015, $3.8 million and $40.4 million of Head Lease receipts had been deferred and included in unearned revenue and other long-term liabilities, respectively, in the Partnership’s consolidated balance sheets. (ii) The amount of payments under the Subleases are updated annually to reflect any changes in the lease payments due to changes in tax law. Net Investments in Direct Financing Leases The Tangguh LNG Carriers commenced their time-charters with its charterers in January and May 2009, respectively. Both time-charters are accounted for as direct financing leases with 20-year terms. In September and November 2013, the Partnership acquired two 155,900-cubic meter LNG carriers (or Awilco LNG Carriers Awilco December 31, $ December 31, $ Total minimum lease payments to be received 843,079 914,943 Estimated unguaranteed residual value of leased properties 194,965 194,965 Initial direct costs 425 458 Unearned revenue (371,811 ) (427,871 ) Total 666,658 682,495 Less current portion 20,606 15,837 Net investments in direct financing leases - non-current 646,052 666,658 As at December 31, 2015, estimated minimum lease payments to be received by the Partnership under the Tangguh LNG Carrier leases in each of the next five succeeding fiscal years are approximately $39.1 million per year from 2016 through 2021. Both leases are scheduled to end in 2029. In addition, estimated minimum lease payments in the next three years to be received by the Partnership under the Awilco LNG Carrier leases are approximately $35.9 million (2016), $165.0 million (2017) and $134.6 million (2018). Operating Leases As at December 31, 2015, the minimum scheduled future revenues in the next five years to be received by the Partnership for the lease and non-lease elements under charters that were accounted for as operating leases are approximately $349.5 million (2016), $351.9 million (2017), $397.2 million (2018), $428.2 million (2019) and $419.1 million (2020). Minimum scheduled future revenues do not include revenue generated from new contracts entered into after December 31, 2015, revenue from vessels in the Partnership’s equity accounted investments, revenue from unexercised option periods of contracts that existed on December 31, 2015, or variable or contingent revenues. Therefore, the minimum scheduled future revenues should not be construed to reflect total charter hire revenues for any of the years.

Through this transaction, the Partnership has a 30% ownership interest in two LNG carrier newbuildings and a 20% ownership interest in the remaining two LNG carrier newbuildings (collectively, the BG Joint Venture The excess of the Partnership’s investment in the BG Joint Venture over the Partnership’s share of the underlying carrying value of net assets acquired was approximately $16.8 million in accordance with the final purchase price allocation. This basis difference has been allocated notionally to the ship construction support agreements and the time-charter contracts. The Partnership accounts for its investment in the BG Joint Venture using the equity method. As at December 31, 2015, to fund its newbuilding installments, the BG Joint Venture has drawn $89.0 million (December 31, 2014 – $53.7 million) from its $787.0 million long-term debt facility and received $8.6 million of capital contributions from the Partnership (December 31, 2014 – $3.8 million), representing the Partnership’s proportionate share. d) Exmar LPG Joint Venture In February 2013, the Partnership entered into a 50/50 joint venture agreement with Belgium-based Exmar NV (or Exmar Exmar LPG Joint Venture In June 2015, the Exmar LPG Joint Venture completed refinancing its existing debt facility by entering into a $460.0 million long-term debt facility bearing interest at a rate of LIBOR plus 1.90%, maturing in 2021. The Partnership has guaranteed its 50% share of the secured loan facility in the Exmar LPG Joint Venture and, as a result, recorded a guarantee liability of $1.7 million. The carrying value of the guarantee liability as at December 31, 2015 was $1.5 million and is included as part of other long-term liabilities in the Partnership’s consolidated balance sheets. In addition, during 2015, the Exmar LPG Joint Venture entered into three interest rate swap agreements with an aggregate notional amount of $375.7 million, which amortize quarterly over the term of the interest rate swap agreements to $161.2 million at maturity. The interest rate swap agreements exchange the receipts of LIBOR-based interest for the payments of a fixed rate ranging from 1.69% to 1.84% excluding the margin. These interest rate swap agreements have been designated as a qualifying cash flow hedging instruments for accounting purposes. The Exmar LPG Joint Venture uses the same accounting policy for qualifying cash flow hedging instruments as the Partnership. e) Teekay LNG-Marubeni Joint Venture The Partnership has a 52% ownership interest in the joint venture between Marubeni Corporation and the Partnership (or the Teekay LNG-Marubeni Joint Venture In July 2013, the Teekay LNG-Marubeni Joint Venture entered into an eight-year interest rate swap agreement with a notional amount of $160.0 million, which amortizes quarterly over the term of the interest rate swap agreement to $70.4 million at maturity. The interest rate swap agreement exchanges the receipt of LIBOR-based interest for the payment of a fixed rate of interest of 2.20% in the first two years and 2.36% in the last six years. This interest rate swap agreement has been designated as a qualifying cash flow hedging instrument for accounting purposes. The Teekay LNG-Marubeni Joint Venture uses the same accounting policy for qualifying cash flow hedging instruments as the Partnership uses. One of Teekay LNG-Marubeni Joint Venture’s loan facilities for four of its six LNG carriers contains mandatory prepayment provisions upon early termination of a charter and requires the borrower to maintain a specific debt service coverage ratio.

These joint ventures are accounted for using the equity method. The RasGas 3 Joint Venture, the Excelsior Joint Venture, the Angola Joint Venture and the Yamal LNG Joint Venture are considered variable interest entities; however, the Partnership is not the primary beneficiary and consolidation of these entities with the Partnership is not required. The Partnership’s maximum exposure to loss as a result of its investment in the RasGas 3 Joint Venture, the Excelsior Joint Venture, the Angola LNG Joint Ventures and the Yamal LNG Joint Venture is the amount it has invested and advanced in these joint ventures, which are $161.4 million, $49.0 million, $58.2 million and $99.9 million respectively, as at December 31, 2015. In addition, the Partnership guarantees its portion of the Excelsior Joint Venture’s debt of $47.5 million and the Angola Joint Ventures’ debt and swaps of $272.0 million and guarantee for charter termination of $1.2 million.

Interest payments are based on LIBOR plus margins, which ranged from 0.55% to 1.10%. The amount available under the three revolving credit facilities reduces by $177.3 million (2016), $28.2 million (2017) and $253.7 million (2018). The revolving credit facilities may be used by the Partnership to fund general partnership purposes and to fund cash distributions. The Partnership is required to repay all borrowings used to fund cash distributions within 12 months of their being drawn, from a source other than further borrowings. One of the revolving credit facilities is unsecured while the other two revolving credit facilities are collateralized by first-priority mortgages granted on four of the Partnership’s vessels, together with other related security, and include a guarantee from the Partnership or its subsidiaries of all outstanding amounts. As at December 31, 2015, the Partnership had a U.S. Dollar-denominated term loan outstanding in the amount of $50.4 million. Interest payments on this loan are based on LIBOR plus 1.00% with a bullet repayment of $50.4 million due at maturity in 2016.

The Teekay Tangguh Joint Venture has a U.S. Dollar-denominated term loan outstanding, which, as at December 31, 2015, totaled $272.0 million. Interest payments on the loan are based on LIBOR plus margins. Interest payments on one tranche under the loan facility are based on LIBOR plus 0.30%, while interest payments on the second tranche are based on LIBOR plus 0.63%. One tranche reduces in quarterly payments while the other tranche correspondingly is drawn up with a final $95.0 million bullet payment for each of two vessels due in 2021. This loan facility is collateralized by first-priority mortgages on the two vessels to which the loan relates, together with certain other security and is guaranteed by the Partnership. As at December 31, 2015, the Partnership had a U.S. Dollar-denominated term loan outstanding in the amount of $88.3 million. Interest payments on one tranche under the loan facility are based on LIBOR plus 0.30%, while interest payments on the second tranche are based on LIBOR plus 0.70%.

As at December 31, 2015, the carrying amount of the bonds was $101.8 million and the bonds are listed on the Oslo Stock Exchange. The interest payments on the bonds are based on NIBOR plus a margin of 4.35%. The Partnership has a cross-currency swap, to swap all interest and principal payments into U.S. Dollars, with the interest payments fixed at a rate of 6.43% (see Note 13) and the transfer of principal fixed at $150.0 million upon maturity in exchange for NOK 900 million. The Partnership has NOK 1,000 million of senior unsecured bonds that mature in May 2020 in the Norwegian bond market. As at December 31, 2015, the carrying amount of the bonds was $113.1 million and the bonds are listed on the Oslo Stock Exchange. The interest payments on the bonds are based on NIBOR plus a margin of 3.70%. The Partnership has a cross currency swap (see Note 13), to swap all interest and principal payments into U.S. Dollars, with the interest payments fixed at a rate of 5.92% and the transfer of principal fixed at $134.0 million upon maturity in exchange for NOK 1,000 million. The Partnership has two Euro-denominated term loans outstanding, which as at December 31, 2015, totaled 222.7 million Euros ($241.8 million). Interest payments are based on EURIBOR plus margins, which ranged from 0.60% to 2.25% as of December 31, 2015, and the loans require monthly interest and principal payments. The term loans have varying maturities through 2023. The term loans are collateralized by first-priority mortgages on two vessels to which the loans relate, together with certain other related security and are guaranteed by the Partnership and one of its subsidiaries. The weighted-average effective interest rate for the Partnership’s long-term debt outstanding at December 31, 2015 and December 31, 2014 was 2.33% and 2.19%, respectively. This rate does not reflect the effect of related interest rate swaps that the Partnership has used to economically hedge certain of its floating-rate debt (see Note 13). At December 31, 2015, the margins on the Partnership’s outstanding revolving credit facilities and term loans ranged from 0.30% to 2.80%. 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, capital leases and restricted cash, and the change in the valuation of the Partnership’s cross-currency swaps, the Partnership incurred foreign exchange gains (losses) of $13.9 million, $28.4 million and ($15.8) million, which amounts were primarily unrealized, for the years ended December 31, 2015, 2014 and 2013, respectively. The aggregate annual long-term debt principal repayments required after December 31, 2015 are $198.3 million (2016), $210.7 million (2017), $796.5 million (2018), $70.1 million (2019), $186.3 million (2020) and $553.6 million (thereafter). The Partnership and a subsidiary of Teekay Corporation are borrowers under a loan arrangement and are joint and severally liable for the obligations to the lender. Obligations resulting from long-term debt joint and several liability arrangements are measured at the sum of the amount the Partnership agreed to pay, on the basis of its arrangement among the co-obligor, and any additional amount the Partnership expects to pay on behalf of the co-obligor. This loan arrangement matures in 2021 and as of December 31, 2015 had an outstanding balance of $173.9 million, of which $88.3 million was the Partnership’s share. Teekay Corporation has indemnified the Partnership in respect of any losses and expenses arising from any breach by the co-obligor of the terms and conditions of the loan facility. Certain loan agreements require that (a) the Partnership maintains minimum levels of tangible net worth and aggregate liquidity, (b) the Partnership maintains certain ratios of vessel values as it relates to the relevant outstanding loan principal balance, (c) the Partnership not exceed a maximum amount of leverage, and (d) certain of the Partnership’s subsidiaries maintains restricted cash deposits. The Partnership has one facility that requires us to maintain a vessel-value-to-outstanding-loan-principal-balance ratio of 115%, which as at December 31, 2015, was 194%. The vessel value was determined using reference to second-hand market comparables or using a depreciated replacement cost approach. 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 is in default under its term loans or revolving credit facilities. One of the Partnership’s term loans is guaranteed by Teekay Corporation and contains covenants that require Teekay Corporation to maintain the greater of a minimum liquidity (cash and cash equivalents) of at least $50.0 million and 5.0% of Teekay Corporation’s total consolidated debt which has recourse to Teekay Corporation. As at December 31, 2015, the Partnership, and Teekay Corporation and their affiliates were in compliance with all covenants relating to the Partnership’s credit facilities and term loans.

Derivative Instruments	13. Derivative Instruments The Partnership uses derivative instruments in accordance with its overall risk management policy. The Partnership has not designated derivative instruments described within this note as hedges for accounting purposes. Foreign Exchange Risk Through 2012 to 2015, concurrently with the issuance of NOK 700 million, NOK 900 million and NOK 1,000 million, of senior unsecured bonds (see Note 10) during that time, the Partnership entered into cross-currency swaps, 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-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-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 2017, 2018 and 2020, and to economically hedge the interest rate exposure. The following table reflects information relating to the cross-currency swaps as at December 31, 2015.

As at December 31, 2015, the Partnership had multiple interest rate swaps and cross-currency swaps with the same counterparty that are subject to the same master agreement. Each of these master agreements provide for the net settlement of all swaps subject to that master agreement through a single payment in the event of default or termination of any one swap. The fair value of these interest rate swaps are presented on a gross basis in the Partnership’s consolidated balance sheets. As at December 31, 2015, these interest rate swaps and cross-currency swaps had an aggregate fair value liability amount of $209.2 million. As at December 31, 2015, the Partnership had $44.8 million on deposit as security for swap liabilities under certain master agreements. The deposit is presented in restricted cash on the Partnership’s consolidated balance sheets. 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 Toledo Spirit The following table presents the location and fair value amounts of derivative instruments, segregated by type of contract, on the Partnership’s consolidated balance sheets.

Limited Partners' Rights Significant rights of the Partnership’s limited partners include the following: • Right 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 for 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 conducts, directs and manages the Partnership’s activities. • The General Partner may be removed if such removal is approved by 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 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 2015, cash distributions with respect to the first three quarters of 2015 exceeded $0.4625 per common unit, and were below $0.4625 per common unit with respect to the distribution for the fourth quarter of 2015. Consequently, the assumed distribution of net income 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 up to September 30, 2015 and increasing percentages were not used to calculate the General Partner’s interest in net income for the purposes of the net income per common unit calculation from October 1, 2015 to December 31, 2015. In the event of a liquidation, all property and cash in excess of that required to discharge all liabilities will be distributed to the 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 Unit Net income per unit is determined by dividing net income, after deducting the amount of net income attributable to the non-controlling interest and the General Partner’s interest, by the weighted-average number of units outstanding during the period. 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 board of directors 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 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.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Unit-Based Compensation	17. Unit-Based Compensation In March 2015, a total of 10,447 common units, with an aggregate value of $0.4 million, were granted to the non-management directors of the General Partner as part of their annual compensation for 2015. These common units were fully vested upon grant. During 2014 and 2013, the Partnership awarded 9,521 and 7,362 common units, respectively, as compensation to non-management directors. The awards were fully vested in March 2014 and March 2013, respectively. The compensation to the non-management directors is included in general and administrative expenses on the Partnership’s consolidated statements of income. During March 2015, 2014 and 2013, the Partnership granted 32,054, 31,961 and 36,878 restricted units, respectively, with grant date fair values of $1.1 million, $1.3 million and $1.5 million, respectively, based on the Partnership’s closing unit price on the grant date, to certain of the Partnership’s employees and to certain employees of Teekay Corporation’s subsidiaries who provide services to the Partnership. Each restricted unit represents 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 cancelled, 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 units, net of withholding tax. During the years ended December 31, 2015, 2014 and 2013, the Partnership recorded an expense of $1.2 million, $1.0 million, and $1.0 million, respectively, related to the restricted units.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (or GAAP Partnership Significant intercompany balances and transactions have been eliminated upon consolidation. In addition, certain of the comparative figures as at December 31, 2014 have been reclassified to conform to the presentation adopted in the current period relating to debt issuance costs. As part of the adoption of Accounting Standards Update 2015-03, Simplifying the Presentation of Debt Issuance Costs ASU 2015-03
Foreign currency	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 separately in the accompanying consolidated statements of income.
Operating revenues and expenses	Operating revenues and expenses The lease element of 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 as the applicable vessel operates under the charter. The lease element of the Partnership’s time-charters that are accounted for as direct financing leases are reflected on the balance sheets as net investments in direct financing leases. The lease element is recognized over the lease term using the effective interest rate method and is included in voyage revenues. The Partnership recognizes revenues from the non-lease element of time-charter contracts as services are performed. The Partnership does not recognize revenues during days that the vessel is off-hire.
Voyage Expenses	Voyage expenses are all expenses unique to a particular voyage, including bunker fuel expenses, port fees, cargo loading and unloading expenses, canal tolls, agency fees and commissions. 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.
Cash and cash equivalents	Cash and cash equivalents The Partnership classifies all highly-liquid investments with a maturity date of three months or less when purchased as cash and cash equivalents.
Accounts receivable and allowance for doubtful accounts	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.
Vessels and equipment	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. 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 LNG Vessel capital modifications include the addition of new equipment or can encompass various modifications to the vessel which are aimed at improving or increasing the operational efficiency and functionality of the asset. This type of expenditure is amortized over the estimated useful life of the modification. Expenditures covering recurring routine repairs and maintenance are expensed as incurred. Interest costs capitalized to vessels and equipment for the years ended December 31, 2015, 2014 and 2013 aggregated $8.2 million, $3.1 million and $1.3 million, respectively. Gains on vessels sold and leased back under capital leases are deferred and amortized over the remaining estimated useful life of the vessel. Losses on vessels sold and leased back under capital leases are recognized immediately to the extent that the fair value of the vessel at the time of sale-leaseback is less than its book value. Generally, the Partnership dry docks each of its vessels every 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 period. 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 over the estimated useful life of the dry dock. The Partnership includes in capitalized dry docking those costs incurred as part of the dry docking to meet 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. 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. The following table summarizes the change in the Partnership’s capitalized dry docking costs, from January 1, 2013 to December 31, 2015: Year Ended December 31, 2015 $ 2014 $ 2013 $ Balance at January 1, 33,635 40,328 28,821 Cost incurred for dry docking 10,357 13,471 27,203 Sales of vessels (note 15e) — (5,327 ) (2,285 ) Dry-dock amortization (10,076 ) (14,837 ) (13,411 ) Balance at December 31, 33,916 33,635 40,328 Vessels and equipment that are “held and used” 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 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 hand sale and purchase market exists, 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.
Investments in and advances to equity accounted joint ventures	Investments in and advances to equity accounted joint ventures The Partnership’s investments in certain joint ventures 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 ventures 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 the estimated fair value is less than the 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.
Debt issuance costs	Debt issuance costs Debt issuance costs, including fees, commissions and legal expenses, are presented as a direct reduction from the carrying amount of the debt liability and are amortized on an effective interest rate method over the term of the relevant loan. Amortization of debt issuance costs is included in interest expense.
Goodwill and intangible assets	Goodwill and intangible assets Goodwill is not amortized, but 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. 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. 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 and 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	Derivative instruments All derivative instruments are initially recorded at fair value as either assets or liabilities in the accompanying consolidated balance sheet and subsequently remeasured to fair value, 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. At December 31, 2015, the Partnership has not applied hedge accounting to its derivative instruments, except for several interest rate swaps in its equity accounted joint ventures (see note 6). 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 possible 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 in the consolidated statements of income. The ineffective portion of the change in fair value of the derivative financial instruments is immediately recognized in earnings in the consolidated statements of income. If a cash flow hedge is terminated and the originally hedged item is still considered possible 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 consolidated statements of income. If the hedged items are no longer possible of occurring, amounts recognized in total equity are immediately transferred to the earnings item in the 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 ASC Derivatives and Hedging Toledo Spirit
Unit-based compensation	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. 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 are reflected in general and administrative expenses in the Partnership’s consolidated statements of income.
Income taxes	Income taxes The Partnership accounts for income taxes using the liability method. All but two of the Partnership’s Spanish-flagged vessels are subject to the Spanish Tonnage Tax Regime (or TTR The Partnership recognizes the benefits of uncertain tax positions when 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, including resolution of any related appeals or litigation processes, based on the technical merits of the position. If a tax position meets the more-likely-than-not recognition threshold, it is measured to determine the amount of benefit to recognize in the financial statements. 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 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 (expense) on the Partnership’s consolidated statements of income as the Partnership’s risk from the guarantees declines 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.
Accumulated other comprehensive (loss) income	Accumulated other comprehensive (loss) income The following table contains the changes in the balance of the Partnership’s only component of accumulated other comprehensive (loss) income for the periods presented: Qualifying Cash Flow Hedging Instruments $ Balance as at December 31, 2013 131 Other comprehensive loss (1,534 ) Balance as at December 31, 2014 (1,403 ) Other comprehensive loss (648 ) Balance as at December 31, 2015 (2,051 )
Accounting Pronouncements	In April 2014, the FASB issued Accounting Standards Update 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity ASU 2014-08 In May 2014, the FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers ASU 2014-09 In February 2015, the FASB issued Accounting Standards Update 2015-02, Amendments to the Consolidation Analysis ASU 2015-02 In April 2015, the FASB issued ASU 2015-03. The Partnership adopted ASU 2015-03 effective December 31, 2015. Prior period information has been retrospectively adjusted. Prior to the adoption of ASU 2015-03, all debt issuance costs were presented as other non-current assets in the Partnership’s consolidated balance sheets. With the adoption of ASU 2015-03 the Partnership presents those debt issuance costs related to a recognized debt liability as a direct deduction from the carrying amount of that debt liability in the Partnership’s consolidated balance sheets. Debt issuance costs related to loan facilities without a recognized debt liability will continue to be presented as non-current assets in the Partnership’s consolidated balance sheets.

Description of capital lease, lessee	Teekay Nakilat Joint Venture 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).
Description of capital leases, indemnification agreements	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.
