Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The unaudited interim consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (or GAAP). These financial statements include the accounts of Teekay Offshore Partners L.P., which is a limited partnership organized under the laws of the Republic of The Marshall Islands and its wholly owned or controlled subsidiaries (collectively, the Partnership). The preparation of 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 could differ from those estimates.

Certain information and footnote disclosures required by GAAP for complete annual financial statements have been omitted and therefore, these interim financial statements should be read in conjunction with the Partnership’s audited consolidated financial statements for the year ended December 31, 2013, which are included in the Partnership’s Annual Report on Form 20-F. In the opinion of management of our general partner, Teekay Offshore GP L.L.C. (or the General Partner), these interim unaudited consolidated financial statements reflect all adjustments, which are of a normal recurring nature, necessary to present fairly, in all material respects, the Partnership’s consolidated financial position, results of operations, changes in total equity and cash flows for the interim periods presented. The results of operations for the interim periods presented are not necessarily indicative of those for a full fiscal year. Historically, the utilization of shuttle tankers in the North Sea is higher in the winter months and lower in the summer months, as generally there is higher maintenance in the oil fields during the summer months, which leads to lower oil production, and thus, lower shuttle tanker utilization during that period. Significant intercompany balances and transactions have been eliminated upon consolidation.

In the current period the Partnership has presented the conversion costs for the Partnership’s committed vessel conversions in Advances on newbuilding contracts and conversion costs. Prior to June 30, 2014, the Partnership included these amounts in Vessels and equipment – At cost, less accumulated depreciation. All such costs incurred in comparative periods have been reclassified from Vessels and equipment – At cost, less accumulated depreciation to Advances on newbuilding contracts and conversion costs to conform to the presentation adopted in the current period. The amount reclassified as at December 31, 2013 was $29.8 million.

Accounting Pronouncement Not Yet Adopted

Accounting Pronouncement Not Yet Adopted

In May 2014, the Financial Accounting Standards Board (or FASB) issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers, (or ASU 2014-09). ASU 2014-09 will require entities to recognize revenue when it transfers promised goods or services to customers in 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 when each performance obligation is satisfied. ASU 2014-09 is effective for interim and annual periods beginning after December 15, 2016 and shall be applied retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. Early adoption is not permitted. The Partnership is evaluating the effect of adopting this new accounting guidance.

In April 2014, the FASB issued Accounting Standards Update 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity (or ASU 2014-08) which raises the threshold for disposals to qualify as discontinued operations. A discontinued operation is defined as: (i) a component of an entity or group of components that has been disposed of or classified as held for sale and represents a strategic shift that has or will have a major effect on an entity’s operations and financial results; or (ii) an acquired business that is classified as held for sale on the acquisition date. ASU 2014-08 also requires additional disclosures regarding discontinued operations, as well as material disposals that do not meet the definition of discontinued operations. ASU 2014-08 is effective for fiscal years beginning on or after December 15, 2014, and interim periods within those years. Early adoption is permitted, but only for disposals (or classifications as held for sale) that have not been reported in the financial statements previously issued or available for issuance. The impact, if any, of adopting ASU 2014-08 on the Partnership’s financial statements will depend on the occurrence and nature of disposals that occur after ASU 2014-08 is adopted.

Accounting Policies [Abstract]

Basis of Presentation

1. Basis of Presentation

The unaudited interim consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (or GAAP). These financial statements include the accounts of Teekay Offshore Partners L.P., which is a limited partnership organized under the laws of the Republic of The Marshall Islands and its wholly owned or controlled subsidiaries (collectively, the Partnership). The preparation of 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 could differ from those estimates.

Certain information and footnote disclosures required by GAAP for complete annual financial statements have been omitted and therefore, these interim financial statements should be read in conjunction with the Partnership’s audited consolidated financial statements for the year ended December 31, 2013, which are included in the Partnership’s Annual Report on Form 20-F. In the opinion of management of our general partner, Teekay Offshore GP L.L.C. (or the General Partner), these interim unaudited consolidated financial statements reflect all adjustments, which are of a normal recurring nature, necessary to present fairly, in all material respects, the Partnership’s consolidated financial position, results of operations, changes in total equity and cash flows for the interim periods presented. The results of operations for the interim periods presented are not necessarily indicative of those for a full fiscal year. Historically, the utilization of shuttle tankers in the North Sea is higher in the winter months and lower in the summer months, as generally there is higher maintenance in the oil fields during the summer months, which leads to lower oil production, and thus, lower shuttle tanker utilization during that period. Significant intercompany balances and transactions have been eliminated upon consolidation.

In the current period the Partnership has presented the conversion costs for the Partnership’s committed vessel conversions in Advances on newbuilding contracts and conversion costs. Prior to June 30, 2014, the Partnership included these amounts in Vessels and equipment – At cost, less accumulated depreciation. All such costs incurred in comparative periods have been reclassified from Vessels and equipment – At cost, less accumulated depreciation to Advances on newbuilding contracts and conversion costs to conform to the presentation adopted in the current period. The amount reclassified as at December 31, 2013 was $29.8 million.

Discontinued Operations

14. Discontinued Operations

The operations of the Leyte Spirit, the Poul Spirit and the Gotland Spirit prior to being considered discontinued operations, were reported within the conventional tanker segment. The Leyte Spirit, which was written down in 2012, was sold in the first quarter of 2013. In the first and second quarters of 2013, the Poul Spirit and the Gotland Spirit, respectively, were written down to their estimated fair values in conjunction with the termination of their long-term time-charter-out contracts with a subsidiary of Teekay Corporation. The Partnership received early termination fees of $4.5 million and $6.8 million from Teekay Corporation in the second quarter and first quarter of 2013, respectively, which are recorded in discontinued operations. The Poul Spirit was further written down upon sale in the second quarter of 2013 and a gain was recognized upon the sale of the Gotland Spirit in the third quarter of 2013. The estimated fair value for each of the three vessels was determined using appraised values. The following table summarizes the net loss from discontinued operations related to these three vessels for the period presented in the consolidated statements of income:

Acquisition of Logitel

In August 2014, the Partnership acquired 100% of the outstanding shares of Logitel Offshore Holding AS (Logitel), a Norway-based company focused on the high-end floating accommodation market. The purchase price for the shares of Logitel consisted of $4.0 million in cash due on closing and a potential additional cash amount of $27.6 million, subject to reductions of some or all of this potential additional amount if certain performance criteria, primarily relating to the construction of the three floating accommodation units (FAUs) ordered from the COSCO (Nantong) Shipyard (COSCO) in China, are not met. Two of the FAUs are currently under construction and in August 2014, the Partnership exercised one of its existing six options with COSCO to construct a third FAU. Prior to the acquisition, Logitel secured a three-year fixed-rate charter contract, plus extension options, with Petroleo Brasileiro SA (Petrobras) in Brazil for the first FAU which is scheduled to deliver in the first quarter of 2015. The Partnership expects to secure charter contracts for the remaining two newbuilding FAUs prior to their respective scheduled deliveries in the fourth quarter of 2015 and the third quarter of 2016.

The Partnership is committed to acquire the three FAUs ordered from COSCO for a total cost of approximately $534.0 million, including estimated site supervision costs and license fees to be paid to Sevan Marine ASA (or Sevan) to allow for use of its cylindrical hull design in these FAUs. As at the date of acquisition, payments made towards these commitments totaled $18.0 million and the remaining payments required to be made under these newbuilding contracts are $8.8 million (balance of 2014), $341.0 million (2015) and $166.2 million (2016). The amount of the license fees, in aggregate for the three FAUs ordered from COSCO, is $22.2 million, subject to reductions of some or all of this amount if certain performance criteria, primarily relating to the construction of the three FAUs ordered from COSCO, is not met. The amount of site supervision costs are based on hours spent at agreed upon hourly rates as per the Partnership’s agreement with Sevan.

The Partnership intends to finance the initial newbuilding payments through its existing liquidity and expects to secure long-term debt financing for the units prior to their scheduled deliveries. Prior to the acquisition, financing for $60.0 million of costs incurred by Logitel relating to the acquisition of two partially completed hulls from Sevan and the subsequent construction installments to COSCO has been provided by a bond agreement between Logitel and Sevan, The Partnership has assumed Logitel’s obligations under the bond agreement as part of this acquisition. The bond is non-interest bearing and is repayable in amounts of $10.0 million within 6 months of delivery of each of the next six FAUs, including the three ordered from COSCO. The bonds are redeemable at par at any time by Logitel. The bonds are convertible by Sevan. The conversion option is exercisable if the fourth of six options with COSCO is not exercised by its option expiry date on November 30, 2016, In this case, Sevan has a one-time option to receive the remaining two options with COSCO in exchange for the extinguishment of the remaining amount owing on the bond agreement. If the one-time option is not exercised by Sevan, any remaining amount owing on the bond agreement will be forgiven when there is a continuous three-year period, from the date of the latest delivery of a newbuilding FAU based on the Sevan cylindrical hull design, where no such Sevan design FAUs are ordered.

Derivative Instruments and Hedging Activities

9. Derivative Instruments and Hedging Activities

The Partnership uses derivatives to manage certain risks in accordance with its overall risk management policies.

Foreign Exchange Risk

The Partnership economically hedges portions of its forecasted expenditures denominated in foreign currencies with foreign currency forward contracts. The Partnership has not designated, for accounting purposes, these foreign currency forward contracts as cash flow hedges.

As at June 30, 2014, the Partnership was committed to the following foreign currency forward contracts:

	Contract Amount		Fair Value / Carrying
	in Foreign		Amount of Asset (Liability)			Average		Expected Maturity
	Currency		(in thousands of U.S. Dollars)			Forward		2014		2015
	(thousands)		Non-hedge			Rate(1)		(in thousands of U.S. Dollars)
Norwegian Kroner		410,000		(164	)		6.16		30,526		36,004

(1) Average forward rate represents the contracted amount of foreign currency one U.S. Dollar will buy.

The Partnership enters into cross currency swaps and pursuant to these swaps the Partnership receives the principal amount in Norwegian Kroner (or NOK) on the maturity date of the swap, in exchange for payment 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 at maturity of the Partnership’s Norwegian Kroner Bonds due through 2019. In addition, the cross currency swaps due from 2016 through 2019 economically hedge the interest rate exposure on the Norwegian Kroner Bonds due in 2016 through 2019. The Partnership has not designated, for accounting purposes, these cross currency swaps as cash flow hedges of its Norwegian Kroner Bonds due through 2019. As at June 30, 2014, the Partnership was committed to the following cross currency swaps:

									Fair Value /
									Carrying
Principal	Principal	Floating Rate Receivable							Amount of			Remaining
Amount	Amount	Reference				Fixed Rate			Asset			Term
NOK	USD	Rate	Margin			Payable			(Liability)			(years)
600,000	101,351	NIBOR		5.75	%		7.49	%		(6,337	)	2.6
500,000	89,710	NIBOR		4.00	%		4.80	%		(8,943	)	1.6
800,000	143,536	NIBOR		4.75	%		5.93	%		(14,285	)	3.6
1,000,000	162,200	NIBOR		4.25	%		6.28	%		(2,621	)	4.6
										(32,186	)

Interest Rate Risk

The Partnership enters into interest rate swaps, which exchange a receipt of floating interest for a payment of fixed interest, to reduce the Partnership’s exposure to interest rate variability on its outstanding floating-rate debt. The Partnership has not designated, for accounting purposes, its interest rate swaps as cash flow hedges of its U.S. Dollar LIBOR-denominated borrowings.

As at June 30, 2014, the Partnership was committed to the following interest rate swap agreements:

					Fair Value /
					Carrying			Weighted-
					Amount of			Average		Fixed
	Interest		Notional		Assets			Remaining		Interest
	Rate		Amount		(Liability)			Term		Rate
	Index		$		$			(years)		(%)(1)
U.S. Dollar-denominated interest rate swaps (2)		LIBOR		800,000		(139,215	)		8.4		4.7
U.S. Dollar-denominated interest rate swaps (3)		LIBOR		815,781		(45,147	)		6.1		2.5
U.S. Dollar-denominated interest rate swaps (4)		LIBOR		180,000		(3,254	)		0.3		3.4
				1,795,781		(187,616	)

(1) Excludes the margin the Partnership pays on its variable-rate debt, which as at June 30, 2014, ranged between 0.3% and 3.25%.

(2) Notional amount remains constant over the term of the swap.

(3) Principal amount reduces quarterly or semi-annually.

(4) This interest rate swap is being used to economically hedge expected interest payments on new debt that is planned to be outstanding from 2016 to 2028. The interest rate swap is subject to mandatory early termination in 2014 whereby the swap will be settled based on its fair value at that time.

As at June 30, 2014, the Partnership had multiple interest rate swaps and cross currency swaps governed by the same master agreement. Each of these master agreements provides 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 June 30, 2014, these interest rate swaps and cross currency swaps had an aggregate fair value asset amount of $0.7 million and an aggregate fair value liability amount of $187.9 million.

The Partnership is exposed to credit loss in the event of non-performance by the counterparties, all of which are financial institutions, to the foreign currency forward contracts and 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 possible and practical, interest rate swaps are entered into with different counterparties to reduce concentration risk.

3. Dropdown Predecessor

On May 2, 2013, the Partnership acquired from Teekay Corporation its 100% interest in Voyageur LLC, which owns the Voyageur Spirit, a floating, production, storage and off-loading (or FPSO) unit, which operates on the Huntington Field in the North Sea under a five-year contract, plus up to 10 one-year extension options, with E.ON RuRuhrgas UK E&P Limited (or E.ON), for an original purchase price of $540.0 million that was effectively reduced to $505.8 million (see note 8c). The Partnership has accounted for this acquisition as a transfer of a business between entities under common control. The method of accounting for such transfer is similar to the pooling of interests method of accounting. Under this method, the carrying amounts of net assets recognized in the balance sheets of each combining entity are carried forward to the balance sheet of the combined entity, and no other assets or liabilities are recognized as a result of the combination. The excess of the proceeds paid by the Partnership over Teekay Corporation’s historical cost is accounted for as an equity distribution to Teekay Corporation. In addition, transfers of net assets between entities under common control are accounted for as if the transfer occurred from the date that the Partnership and the Voyageur Spirit were both under the common control of Teekay Corporation and had begun operations.

As a result, the Partnership’s consolidated statements of income and cash flows for the three and six months ended June 30, 2013 reflect this unit and its results of operations, referred to herein as the Dropdown Predecessor, as if the Partnership had acquired it when it began operations under the control of Teekay Corporation on April 13, 2013. The effect of adjusting the Partnership’s financial statements to retrospectively account for the common control exchange for the period April 13, 2013 to May 2, 2013 decreased the Partnership’s net income and comprehensive income by $2.2 million for the three and six months ended June 30, 2013.

Acquisition of ALP Maritime Services B.V.

Business Combinations [Abstract]

Acquisition of ALP Maritime Services B.V.

15. Acquisition of ALP Maritime Services B.V.

On March 14, 2014, the Partnership acquired 100% of the shares of ALP. Concurrently with this transaction, the Partnership and ALP entered into an agreement with Niigata Shipbuilding & Repair of Japan for the construction of four state-of-the-art SX-157 Ulstein Design ultra-long distance towing and anchor handling vessel newbuildings. These vessels will be equipped with dynamic positioning capability and are scheduled for delivery in 2016. The Partnership is committed to acquire these newbuildings for a total cost of approximately $258 million (see note 11e).

The Partnership acquired ALP for a purchase price of $2.6 million, which was paid in cash, and also entered into an arrangement to pay additional compensation to three former shareholders of ALP if certain requirements are satisfied. This contingent compensation consists of $2.4 million, which is payable upon the delivery and employment of ALP’s four newbuildings scheduled throughout 2016, and a further amount of up to $2.6 million, which is payable if ALP’s annual operating results from 2017 to 2021 meet certain targets. The Partnership has the option to pay up to 50 percent of this compensation through the issuance of common units of the Partnership. Each of the contingent compensation amounts are payable only if the three shareholders are employed by ALP at the time performance conditions are met. For the three and six months ended June 30, 2014, compensation costs were $0.2 million and were recorded under general and administrative expenses in the Partnership’s consolidated statements of (loss) income. The Partnership also incurred a $1.0 million fee associated with the acquisition and a $1.6 million success fee to Teekay Corporation (see note 8a) for assistance of the acquisition which have been recognized in general and administrative expenses during the first and second quarters of 2014, respectively.

This acquisition of ALP and the related newbuilding orders represent the Partnership’s entrance into the long-haul ocean towage and offshore installation services business. This acquisition allows the Partnership to combine its infrastructure and access to capital with ALP’s experienced management team to further grow this niche business, which is in an adjacent sector to the Partnership’s FPSO and shuttle tanker businesses. The acquisition of ALP was accounted for using the purchase method of accounting, based upon preliminary estimates of fair value.

The following table summarizes the preliminary estimates of fair values of the ALP assets acquired and liabilities assumed by the Partnership on the acquisition date.

The goodwill recognized in connection with the ALP acquisition is attributable primarily to the assembled workforce of ALP, including their experience, skills and abilities. Operating results of ALP are reflected in the Partnership’s financial statements commencing March 14, 2014, the effective date of acquisition. For the six months ended June 30, 2014, the Partnership recognized $0.2 million of revenue and $1.7 million of net loss, respectively, resulting from this acquisition. The following table shows comparative summarized consolidated pro forma financial information for the Partnership for the six months ended June 30, 2014 and 2013, giving effect to the Partnership’s acquisition of ALP as if it had taken place on January 1, 2013:

Commitments and Contingencies

11. Commitments and Contingencies

a) On November 13, 2006, one of the Partnership’s shuttle tankers, the Navion Hispania, collided with the Njord Bravo, an FSO unit, while preparing to load an oil cargo from the Njord Bravo. The Njord Bravo services the Njord field, which is operated by Statoil Petroleum AS (or Statoil) and is located off the Norwegian coast. At the time of the incident, Statoil was chartering the Navion Hispania from the Partnership. The Navion Hispania and the Njord Bravo both incurred damage as a result of the collision. In November 2007, Navion Offshore Loading AS (or NOL) and Teekay Navion Offshore Loading Pte Ltd. (or TNOL), subsidiaries of the Partnership, and Teekay Shipping Norway AS (or TSN), a subsidiary of Teekay Corporation, were named as co-defendants in a legal action filed by Norwegian Hull Club (the hull and machinery insurers of the Njord Bravo), several other insurance underwriters and various licensees in the Njord field. The Plaintiffs sought damages for vessel repairs, expenses for a replacement vessel and other amounts related to production stoppage on the field, totaling NOK 213,000,000 (approximately $34.7 million).

The appellate court in June 2013 held that NOL, TNOL and TSN are jointly and severally responsible towards the Plaintiffs for all the losses as a result of the collision, plus interests accrued on the amount of damages. In addition, Statoil ASA was held not to be under an obligation to indemnify NOL, TNOL and TSN for the losses. NOL, TNOL and TSN were also held liable for legal costs associated with court proceedings. As a result of this judgment, in the second quarter of 2013, the Partnership recognized a liability in the amount of NOK 213,000,000 in respect of damages, NOK 66,000,000 in respect of interest and NOK 11,000,000 in respect of legal costs, totaling NOK 290,000,000 (approximately $47.3 million), to the Plaintiffs recorded in accrued liabilities. In the fourth quarter of 2013, the Partnership recognized an additional liability of NOK 4,000,000 in respect of interest, bringing the total liability to NOK 294,000,000 (approximately $47.9 million). The judgment rendered deals with liability only and the ultimate amount of damages may be reduced compared to the NOK 213,000,000 claimed by the Plaintiffs.

The Partnership and Teekay Corporation maintain protection and indemnity insurance for damages to the Navion Hispania and insurance for collision-related costs and claims. These insurance policies are expected to cover the costs related to this incident, including any costs not indemnified by Statoil, and thus a receivable of NOK 294,000,000 (approximately $47.9 million) was concurrently recorded in accounts receivable, which equals the total cost of the claim. In addition, Teekay Corporation has agreed to indemnify the Partnership for any losses it may incur in connection with this incident.

In the fourth quarter of 2013, the insurer made payments directly to the Plaintiffs in full settlement of interest and partial settlement of legal costs and thus the Partnership, as at December 31, 2013, reduced its liability and related receivable to NOK 213,000,000 in respect of damages and approximately NOK 3,400,000 in respect of legal costs, totaling approximately NOK 216,400,000 (approximately $35.3 million). No further payments were made during the first six months of 2014.

b) During 2010, an unrelated party contributed a 1995-built shuttle tanker, the Randgrid, to a subsidiary of the Partnership for a 33% equity interest in the subsidiary. The non-controlling interest owner in the subsidiary holds a put option which, if exercised, would obligate the Partnership to purchase the non-controlling interest owner’s 33% share in the entity for cash in accordance with a defined formula. The redeemable non-controlling interest is subject to remeasurement if the formulaic redemption amount exceeds the carrying value. No remeasurement was required as at June 30, 2014.

c) In May 2013, the Partnership entered into an agreement with Statoil, on behalf of the field license partners, to provide an FSO unit for the Gina Krog oil and gas field located in the North Sea. The contract will be serviced by a new FSO unit that will be converted from the Randgrid shuttle tanker, which the Partnership currently owns through a 67% owned subsidiary and intends to acquire full ownership of the vessel prior to its conversion. The FSO conversion project is expected to cost approximately $281 million, including amounts reimbursable upon delivery of the unit relating to installation and mobilization, and the cost of acquiring the remaining 33% ownership interest in the Randgrid shuttle tanker. As at June 30, 2014, payments made towards this commitment totaled $27.3 million. Following scheduled completion in early-2017, the newly converted FSO unit will commence operations under a three-year time-charter contract to Statoil, which includes 12 additional one-year extension options.

d) In May 2013, the Partnership entered into a ten-year charter contract, plus extension options, with Salamander Energy plc (or Salamander) to supply a FSO unit in Asia. The Partnership converted its 1993-built shuttle tanker, the Navion Clipper, into an FSO unit for an estimated fully built-up cost of approximately $73 million, including mobilization costs. As at June 30, 2014, payments made towards this commitment totaled $39.9 million. The unit commenced its charter contract with Salamander in mid-August of 2014.

e) In March 2014, the Partnership acquired 100% of the shares of ALP, a Netherlands-based provider of long-haul ocean towage and offshore installation services to the global offshore oil and gas industry. Concurrently with this transaction, the Partnership and ALP entered into an agreement with Niigata Shipbuilding & Repair of Japan for the construction of four state-of-the-art SX-157 Ulstein Design ultra-long distance towing and anchor handling vessel newbuildings. These vessels will be equipped with dynamic positioning capability and are scheduled for delivery in 2016. The Partnership is committed to acquire these newbuildings for a total cost of approximately $258 million. As at June 30, 2014, payments made towards these commitments totaled $46.9 million and the remaining payments required to be made under these newbuilding contracts are $14.4 million (balance of 2014), $77.9 million (2015) and $119.1 million (2016). The Partnership intends to continue financing the newbuilding installments through its existing liquidity and expects to secure long-term debt financing for these vessels prior to their scheduled deliveries in 2016.

Restructuring Charge

7. Restructuring Charge

During the three and six months ended June 30, 2014, the Partnership recorded a restructuring charge reimbursement of $0.8 million for the reorganization of the Partnership’s shuttle tanker marine operations, which were completed during 2013. During the six months ended June 30, 2014, the Partnership incurred $0.6 million of restructuring charges related to the reflagging of one shuttle tanker which commenced in January 2014 and was completed in March 2014.

During the three and six months ended June 30, 2013, the Partnership recognized restructuring charges of $1.0 million and $1.6 million, respectively, relating to the reorganization of the Partnership’s shuttle tanker marine operations, and restructuring charges of $0.4 million and $0.4 million, respectively, relating to the reorganization of the Partnership’s conventional tanker marine operations. The purpose of the restructuring was to create better alignment with the Partnership’s marine operations resulting in a lower cost organization going forward. Both reorganizations were completed by June 30, 2013. Under these plans, the Partnership recorded restructuring charges of $2.0 million and $0.9 million, respectively, in total since these plans began in 2012.

As of June 30, 2014, restructuring liabilities of $0.3 million were recorded in accrued liabilities on the consolidated balance sheet.

(1) Income from vessel operations reflected above for the six months ended June 30, 2014 excludes $3.1 million of the Voyageur Spirit FPSO unit payments relating to the production shortfall during the period January 1, 2014 through to February 21, 2014 and a further $0.4 million relating to unreimbursed vessel operating expenses until the unit has declared on hire as of February 22, 2014. Income from vessel operations for the three and six months ended June 30, 2013 excludes $17.0 million of indemnification payments relating to production shortfalls for both the Dropdown Predecessor period from April 13, 2013 to May 1, 2013 and the period owned by the Partnership from May 2, 2013 to June 30, 2013 as the Voyageur Spirit FPSO unit was declared off-hire retroactive to first oil given the delay in achieving final acceptance from the charterer. The indemnification payments by Teekay Corporation have effectively been treated as a reduction to the purchase price of the Voyageur Spirit (see note 8c).

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

(3) The towage segment has not been disaggregated as its results are not material other than a $1.0 million fee associated with the acquisition of ALP Maritime Services B.V. (or ALP), which was recognized in general and administrative expenses in the consolidated statement of (loss) income for the three and six months ended June 30, 2014, and a $1.6 million success fee to Teekay Corporation for assistance with the acquisition of ALP, which was recognized in general and administrative expenses in the consolidated statement of (loss) income for the three and six months ended June 30, 2014 (see note 8a).

(4) Restructuring recovery of $0.8 million for the three and six months ended June 30, 2014 related to a reimbursement received during the second quarter of 2014, for the reorganization of the Partnership’s shuttle tanker marine operations, which were completed during 2013. Restructuring charge of $0.6 million for the six months ended June 30, 2014 related to the reflagging of one shuttle tanker which commenced in January 2014 and was completed in March 2014 (see note 7).

As at June 30, 2014, the Partnership had eight long-term revolving credit facilities, which, as at such date, provided for total borrowings of up to $862.6 million, of which $279.1 million was undrawn. The total amount available under the revolving credit facilities reduces by $531.6 million (remainder of 2014), $77.8 million (2015), $140.5 million (2016), $39.6 million (2017) and $73.1 million (2018). Subsequent to June 30, 2014, the Partnership received commitments to refinance $330.0 million of revolving credit facilities coming due during the remainder of 2014. The refinancing is expected to be completed in September 2014, and the amount available under the new revolving credit facilities will reduce quarterly by $16.5 million per quarter over five years. Six of the revolving credit facilities are guaranteed by the Partnership and certain of its subsidiaries for all outstanding amounts and contain covenants that require the Partnership to maintain the greater of a minimum liquidity (cash, cash equivalents and undrawn committed revolving credit lines with at least six months to maturity) of at least $75.0 million and 5.0% of the Partnership’s total consolidated debt. Two revolving credit facilities are guaranteed by Teekay Corporation and contain 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. The revolving credit facilities are collateralized by first-priority mortgages granted on 25 of the Partnership’s vessels, together with other related security.

In January 2014, the Partnership issued NOK 1,000 million in senior unsecured bonds that mature in January 2019 in the Norwegian bond market. As of June 30, 2014, the carrying amount of the bonds was $163.1 million. The bonds are listed on the Oslo Stock Exchange. The interest payments on the bonds are based on NIBOR plus a margin of 4.25%. The Partnership entered into a cross currency swap to swap all interest and principal payments into USD, with the interest payments fixed at a rate of 6.28%, and the transfer of the principal amount fixed at $162.2 million upon maturity in exchange for NOK 1,000 million (see note 9).

In January 2013, the Partnership issued in the Norwegian bond market NOK 1,300 million in senior unsecured bonds. The bonds were issued in two tranches maturing in January 2016 (NOK 500 million) and January 2018 (NOK 800 million). As at June 30, 2014, the carrying amount of the bonds was $212.0 million. The bonds are listed on the Oslo Stock Exchange. Interest payments on the tranche maturing in 2016 are based on NIBOR plus a margin of 4.00%. Interest payments on the tranche maturing in 2018 are based on NIBOR plus a margin of 4.75%. The Partnership entered into cross currency rate swaps to swap all interest and principal payments into USD, with interest payments fixed at a rate of 4.80% on the tranche maturing in 2016 and 5.93% on the tranche maturing in 2018 and the transfer of the principal amount fixed at $89.7 million upon maturity in exchange for NOK 500 million on the tranche maturing in 2016 and fixed at $143.5 million upon maturity in exchange for NOK 800 million on the tranche maturing in 2018 (see note 9). As part of this bond issuance, the Partnership repurchased at a premium NOK 388.5 million of a then outstanding NOK 600 million bond with a maturity date in November 2013. In connection with this repurchase of bonds, the Partnership terminated a similar notional amount of the related cross currency swap (see note 9). The Partnership recorded a loss in relation to this repurchase of $1.8 million in its consolidated statement of income for the six months ended June 30, 2013.

The Partnership has NOK 600 million of senior unsecured bonds that mature in January 2017 in the Norwegian bond market. As at June 30, 2014, the carrying amount of the bonds was $97.8 million. The bonds are listed on the Oslo Stock Exchange. The interest payments on the bonds are based on NIBOR plus a margin of 5.75%. The Partnership entered into a cross currency rate swap to swap all interest and principal payments into USD, with the interest payments fixed at a rate of 7.49%, and the transfer of the principal amount fixed at $101.4 million upon maturity in exchange for NOK 600 million (see note 9).

As at June 30, 2014, four of the Partnership’s 50% owned subsidiaries each had an outstanding term loan, which in the aggregate totaled $168.1 million. The term loans reduce over time with quarterly and semi-annual payments and have varying maturities through 2018. These term loans are collateralized by first-priority mortgages on the four shuttle tankers to which the loans relate, together with other related security. As at June 30, 2014, the Partnership had guaranteed $46.5 million of these term loans, which represents its 50% share of the outstanding term loans of three of these 50% owned subsidiaries. The other owner and Teekay Corporation have guaranteed $84.1 million and $37.5 million, respectively, of the outstanding term loans.

As at June 30, 2014, the Partnership had term loans outstanding for the shuttle tankers the Amundsen Spirit, theNansen Spirit, the Peary Spirit, the Scott Spirit, the Samba Spirit and the Lambada Spirit and for the Piranema Spirit and the Voyageur Spirit FPSO units, which in aggregate totaled $847.8 million. For the term loan for the Amundsen Spirit and the Nansen Spirit, one tranche reduces in semi-annual payments while the other tranche correspondingly is drawn up every six months with final bullet payments of $29.0 million due in 2022 and $29.1 million due in 2023, respectively. The Peary Spirit, the Scott Spirit, the Samba Spirit, the Lambada Spirit, the Piranema Spirit and the Voyageur Spirit term loans reduce over time with quarterly or semi-annual payments. These term loans have varying maturities through 2023 and are collateralized by first-priority mortgages on the vessels to which the loans relate, together with other related security. As at June 30, 2014, the Partnership had guaranteed $514.1 million of these term loans and Teekay Corporation had guaranteed $333.7 million.

In May 2014, the Partnership issued $300.0 million in senior unsecured bonds that mature in July 2019 in the US bond market. As of June 30, 2014, the carrying amount of the bonds was $300.0 million. The bonds are listed on the New York Stock Exchange. The interest payments on the bonds are fixed at a rate of 6.0%.

As at June 30, 2014, the Partnership had $171.1 million of ten-year senior unsecured bonds outstanding that mature in December 2023 and were issued in the second half of 2013 in a U.S. private placement to finance the Bossa Nova Spirit and the Sertanejo Spirit shuttle tankers. The bonds accrue interest at a fixed combined rate of 4.96%. The bonds are collateralized by first-priority mortgages on the two vessels to which the bonds relate, together with other related security.

Interest payments on the revolving credit facilities and the term loans are based on LIBOR plus margins. At June 30, 2014 and December 31, 2013, the margins ranged between 0.3% and 3.25%. The weighted-average effective interest rate on the Partnership’s variable rate long-term debt as at June 30, 2014 was 3.3% (December 31, 2013 - 2.7%). This rate does not include the effect of the Partnership’s interest rate swaps (see note 9).

The aggregate annual long-term debt principal repayments required to be made subsequent to June 30, 2014 are $549.5 million (remainder of 2014), $150.7 million (2015), $246.1 million (2016), $349.4 million (2017), $370.4 million (2018), and $877.4 million (thereafter).

The Partnership and a subsidiary of Teekay Corporation are borrowers under a loan arrangement and are jointly and severally liable for the obligations to the lender. The 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 with the co-obligor, and any additional amount the Partnership expects to pay on behalf of the co-obligor. As of June 30, 2014, this loan arrangement had an outstanding balance of $80.9 million, of which $45.9 million was the Partnership’s obligation. 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.

Obligations under the Partnership’s credit facilities are secured by certain vessels, and if the Partnership is unable to repay debt under the credit facilities, the lenders could seek to foreclose on those assets. The Partnership has one revolving credit facility that requires it to maintain a vessel value to drawn principal balance ratio of a minimum of 105%. As at June 30, 2014, this ratio was 144.2%. The vessel value used in this ratio is the appraised value prepared by the Partnership based on second hand sale and purchase market data. A further delay in the recovery of the conventional tanker market could negatively affect this ratio.

As at June 30, 2014, the Partnership and Teekay Corporation were in compliance with all covenants related to the credit facilities and long-term debt.

8. Related Party Transactions and Balances

a) During the three and six months ended June 30, 2014, two conventional tankers, two shuttle tankers and two FSO units of the Partnership were employed on long-term time-charter-out contracts with subsidiaries of Teekay Corporation. During the first and second quarter of 2013, the Partnership terminated the long-term time-charter-out contracts under which two of its conventional tankers were employed with a subsidiary of Teekay Corporation. The Partnership received early termination fees from Teekay Corporation of $6.8 million and $4.5 million, in the first and second quarters of 2013, respectively, which are recorded in discontinued operations (see note 14). Teekay Corporation and its wholly-owned subsidiaries provide substantially all of the Partnership’s commercial, technical, crew training, strategic, business development and administrative service needs. In addition, the Partnership reimburses the General Partner for expenses incurred by the General Partner that are necessary or appropriate for the conduct of the Partnership’s business. Such related party transactions were as follows for the periods indicated:

(1) Includes revenue from long-term time-charter-out contracts and short-term time-charter-out contracts with subsidiaries or affiliates of Teekay Corporation, including management fees from ship management services provided by the Partnership to a subsidiary of Teekay Corporation.

(2) Includes ship management and crew training services provided by Teekay Corporation.

(3) Includes commercial, technical, strategic, business development and administrative management fees charged by Teekay Corporation and reimbursements to Teekay Corporation and our General Partner for costs incurred on the Partnership’s behalf.

(4) Includes a $1.6 million success fee to Teekay Corporation for assistance with the acquisition of ALP during the three and six months ended June 30, 2014.

(5) Interest income for the three and six months ended June 30, 2013 related to the interest received from Teekay Corporation and our General Partner on a $150 million partial prepayment for the Voyageur Spirit. The Partnership received interest at a rate of LIBOR plus a margin of 4.25% on the prepaid funds to Teekay Corporation from February 26, 2013 until the Partnership acquired the FPSO unit on May 2, 2013.

(6) Guarantee fee related to the final bullet payment of the Piranema Spirit FPSO debt facility guaranteed by Teekay Corporation.

(7) Related party transactions relating to three conventional tankers determined to be discontinued operations. This includes revenue from long-term time-charter-out contracts with subsidiaries or affiliates of Teekay Corporation, including the early termination fee described above, and crew training, commercial, technical, strategic and business development management fees charged by Teekay Corporation.

b) At June 30, 2014, due from affiliates totaled $55.8 million (December 31, 2013 - $15.2 million) and due to affiliates totaled $75.6 million (December 31, 2013 - $121.9 million). Due to and from affiliates are non-interest bearing and unsecured, and are expected to be settled within the next fiscal year in the normal course of operations.

c) On May 2, 2013, the Partnership acquired from Teekay Corporation its 100% interest in Voyageur LLC, which owns the Voyageur Spirit FPSO unit, which operates on the Huntington Field in the North Sea under a five-year contract, plus up to 10 one-year extension options, with E.ON Ruhrgas UK GP Limited (or E.ON), for an original purchase price of $540.0 million. The purchase price was financed with the assumption of the $230.0 million debt facility secured by the unit, $270.0 million of cash (of which a partial prepayment of $150.0 million was made to Teekay Corporation in February 2013) and the non-cash issuance of 1.4 million common units to Teekay Corporation, which had a value of $40.0 million at the time Teekay Corporation offered to sell the unit to the Partnership.

On April 13, 2013, the Voyageur Spirit FPSO unit began production and on May 2, 2013, the Partnership acquired the unit from Teekay Corporation. Upon commencing production, the Partnership and its sponsor, Teekay Corporation, had a specified time period to receive final acceptance from the charterer, at which point the unit would commence full operations under the contract with E.ON. However, due to a defect encountered in one of its two gas compressors, the FPSO unit was unable to achieve final acceptance within the allowable timeframe, resulting in the FPSO unit being declared off-hire by the charterer retroactive to April 13, 2013.

On August 27, 2013, repairs to the defective gas compressor on the Voyageur Spirit FPSO were completed and the unit achieved full production capacity. On September 30, 2013, the Partnership entered into an interim agreement with E.ON whereby the Partnership was compensated for production beginning August 27, 2013 until the receipt of final acceptance by E.ON. Compensation was based on actual production relative to the operating capacity of the FPSO unit; however, any restrictions on production as a result of the charterer were included in this compensation. Until declared on hire, Teekay Corporation agreed to indemnify the Partnership for certain production shortfalls and unreimbursed vessel operating expenses. For the period from April 13, 2013 to December 31, 2013, Teekay Corporation has indemnified the Partnership a total of $34.9 million for production shortfalls and unreimbursed repair costs. For the first quarter of 2014, Teekay Corporation indemnified the Partnership for a further $3.1 million and $0.4 million for production shortfalls and unrecovered repair costs to address the compressor issues. On April 4, 2014, the Partnership received the certificate of final acceptance from the charterer, which declared the unit on-hire retroactive to February 22, 2014.

Any amounts paid as indemnification from Teekay Corporation to the Partnership were effectively treated as a reduction in the purchase price paid by the Partnership for the FPSO unit. The $540.0 million original purchase price of the Voyageur Spirit FPSO unit has effectively been reduced to $505.8 million ($275.8 million net of assumed debt of $230.0 million) to reflect total indemnification payments from Teekay Corporation of $38.4 million relating to the period from the date of first oil on April 13, 2013 to when the unit was declared on-hire on February 22, 2014, partially offset by the excess value of $4.3 million relating to the 1.4 million common units issued to Teekay Corporation on the date of closing of the transaction in May 2013 compared to the date Teekay Corporation offered to sell the unit to the Partnership. The excess of the purchase price (net of assumed debt) over the book value of the net assets of $201.8 million has been accounted for as an equity distribution to Teekay Corporation of $74.1 million.

d) On June 10, 2013, the Partnership acquired Teekay Corporation’s 50% interest in OOG-TKP FPSO GmbH & Co KG, a joint venture with Odebrecht, which owns the Itajai FPSO unit, for a purchase price of $53.8 million, which was paid in cash. The Partnership’s investment in the Itajai FPSO unit is accounted for using the equity method. The Itajai FPSO unit achieved first oil in February 2013, at which time the unit commenced operations under a nine-year, fixed-rate time-charter contract with Petrobras, with six additional one-year extension options exercisable by Petrobras.

The purchase price was based on an estimate of the fully built-up cost of the Itajai FPSO unit, including certain outstanding contractual items. As at June 30, 2014, the joint venture had received in connection with the resolution of these contractual items, an aggregate of $6.1 million in reimbursements from the charterer and insurer, which was originally deducted from the Partnership’s purchase price of the Itajai FPSO unit. As a result of these reimbursements, this amount was returned to Teekay Corporation.

e) During the first quarter of 2014, the long-term bareboat contracts employed by two conventional tankers of the Partnership with a joint venture in which Teekay Corporation has a 50% interest were novated under the same terms to a subsidiary of Teekay Corporation. The excess of the contractual rates over the market rates at the time of the novation, was $0.3 million and $0.4 million for the three and six months ended June 30, 2014, respectively, and is accounted for as an equity contribution from Teekay Corporation.

Unit Based Compensation

13. Unit Based Compensation

During the six months ended June 30, 2014, a total of 9,482 common units, with an aggregate value of $0.3 million, were granted and issued to the non-management directors of the General Partner as part of their annual compensation for 2014.

The Partnership grants restricted unit awards as incentive-based compensation to certain employees of Teekay Corporation’s subsidiaries that provide services to the Partnership. During March 2014 and 2013, the Partnership granted 68,153 and 63,309 restricted units, respectively, with fair values of $2.1 million and $1.8 million, respectively, based on the Partnership’s closing unit price on the grant date. 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 cancelled, unless their termination arises as a result of the recipient’s retirement and, in this case, the restricted unit awarded will continue to vest in according with the vesting schedule. Upon vesting, the value of the restricted units is paid to each grantee in the form of common units or cash. During the six months ended June 30, 2014, a total of 63,327 restricted stock units with a fair value of $1.9 million, based on the Partnership’s closing unit price on the grant date, vested and the amount paid to the grantees was made by issuing 6,584 common units and by paying $0.3 million in cash. During the six months ended June 2013, a total of 6,742 restricted stock units with a fair value of $0.2 million, based on the Partnership’s closing unit price on the grant date, vested. During the three and six months ended June 30, 2014 and 2013, the Partnership recorded unit based compensation expense of $0.5 million and $1.9 million, and $0.2 million and $0.5 million, respectively, in general and administrative expenses in the Partnership’s consolidated statements of (loss) income. As of June 30, 2014 and 2013, liabilities relating to cash settled restricted unit awards of $1.1 million and $nil, respectively, were recorded in accrued liabilities on the Partnership’s consolidated balance sheets.

Accounting Changes and Error Corrections [Abstract]

Accounting Pronouncement Not Yet Adopted

2. Accounting Pronouncement Not Yet Adopted

In May 2014, the Financial Accounting Standards Board (or FASB) issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers, (or ASU 2014-09). ASU 2014-09 will require entities to recognize revenue when it transfers promised goods or services to customers in 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 when each performance obligation is satisfied. ASU 2014-09 is effective for interim and annual periods beginning after December 15, 2016 and shall be applied retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. Early adoption is not permitted. The Partnership is evaluating the effect of adopting this new accounting guidance.

In April 2014, the FASB issued Accounting Standards Update 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity (or ASU 2014-08) which raises the threshold for disposals to qualify as discontinued operations. A discontinued operation is defined as: (i) a component of an entity or group of components that has been disposed of or classified as held for sale and represents a strategic shift that has or will have a major effect on an entity’s operations and financial results; or (ii) an acquired business that is classified as held for sale on the acquisition date. ASU 2014-08 also requires additional disclosures regarding discontinued operations, as well as material disposals that do not meet the definition of discontinued operations. ASU 2014-08 is effective for fiscal years beginning on or after December 15, 2014, and interim periods within those years. Early adoption is permitted, but only for disposals (or classifications as held for sale) that have not been reported in the financial statements previously issued or available for issuance. The impact, if any, of adopting ASU 2014-08 on the Partnership’s financial statements will depend on the occurrence and nature of disposals that occur after ASU 2014-08 is adopted.

(1) Income from vessel operations reflected above for the six months ended June 30, 2014 excludes $3.1 million of the Voyageur Spirit FPSO unit payments relating to the production shortfall during the period January 1, 2014 through to February 21, 2014 and a further $0.4 million relating to unreimbursed vessel operating expenses until the unit has declared on hire as of February 22, 2014. Income from vessel operations for the three and six months ended June 30, 2013 excludes $17.0 million of indemnification payments relating to production shortfalls for both the Dropdown Predecessor period from April 13, 2013 to May 1, 2013 and the period owned by the Partnership from May 2, 2013 to June 30, 2013 as the Voyageur Spirit FPSO unit was declared off-hire retroactive to first oil given the delay in achieving final acceptance from the charterer. The indemnification payments by Teekay Corporation have effectively been treated as a reduction to the purchase price of the Voyageur Spirit (see note 8c).

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

(3) The towage segment has not been disaggregated as its results are not material other than a $1.0 million fee associated with the acquisition of ALP Maritime Services B.V. (or ALP), which was recognized in general and administrative expenses in the consolidated statement of (loss) income for the three and six months ended June 30, 2014, and a $1.6 million success fee to Teekay Corporation for assistance with the acquisition of ALP, which was recognized in general and administrative expenses in the consolidated statement of (loss) income for the three and six months ended June 30, 2014 (see note 8a).

(4) Restructuring recovery of $0.8 million for the three and six months ended June 30, 2014 related to a reimbursement received during the second quarter of 2014, for the reorganization of the Partnership’s shuttle tanker marine operations, which were completed during 2013. Restructuring charge of $0.6 million for the six months ended June 30, 2014 related to the reflagging of one shuttle tanker which commenced in January 2014 and was completed in March 2014 (see note 7).

Total Capital and Net Income Per Common Unit

6 Months Ended

Jun. 30, 2014

Equity [Abstract]

Total Capital and Net Income Per Common Unit

12. Total Capital and Net Income Per Common Unit

At June 30, 2014, a total of 72.2% 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 a subsidiary of Teekay Corporation. All of the Partnership’s Series A Preferred Units (defined below) outstanding are held by the public.

In 2013, the Partnership implemented a continuous offering program (or COP) under which the Partnership may issue new common units, representing limited partner interests, at market prices up to a maximum aggregate amount of $100 million. For the six months ended June 30, 2014 and 2013, the Partnership sold an aggregate of 213,350 and 85,508 common units, respectively, under the COP, generating proceeds of approximately $7.6 million and $2.7 million, respectively, (including the General Partner’s 2% proportionate capital contribution of $0.2 million and $0.1 million, respectively, and net of approximately $0.2 million and $0.1 million, respectively, of offering costs). The net proceeds from the issuance of these common units were used for general partnership purposes.

Net Income Per Common Unit

Limited partners’ interest in net income per common unit – basic is determined by dividing net income, after deducting the non-controlling interests and the General Partner’s interest and the distributions on the Series A Preferred Units (defined below), by the weighted-average number of common units outstanding during the period. The accumulated distributions on the preferred units for the three and six months ended June 30, 2014 were $2.7 million and $5.4 million, respectively, and $1.8 million for the three and six months ended June 30, 2013. The computation of limited partners’ interest in net income per common unit – diluted assumes the exercise of all dilutive restricted units using the treasury stock method. The computation of limited partners’ interest in net loss per common unit – diluted does not assume such exercises as the effect would be anti-dilutive.

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 less the amount of cash reserves established 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 capital requirements and any accumulated distributions on the Series A Preferred Units (defined below). Unlike available cash, net income is affected by non-cash items such as depreciation and amortization, unrealized gains and losses on derivative instruments and unrealized foreign currency translation gains and losses.

The Partnership allocates the limited partners’ interest in net income, including both distributed and undistributed net income, between continuing operations and discontinued operations based on the proportion of net loss from continuing and discontinued operations to total net income.

During the quarters ended June 30, 2014 and 2013, cash distributions exceeded $0.4025 per common unit and, consequently, the assumed distributions of net (loss) income resulted in the use of the increasing percentages to calculate the General Partner’s interest in net (loss) income for the purposes of the net (loss) income per common unit calculation. For more information on the increasing percentages to calculate the General Partner’s interest in net (loss) income, please refer to the Partnership’s Annual Report on Form 20-F for the year ended December 31, 2013.

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

Preferred Units

In April 2013, the Partnership issued 6.0 million of its 7.25% Series A Cumulative Redeemable Preferred Units (or Series A Preferred Units) in a public offering for net proceeds of $144.9 million.

Pursuant to the partnership agreement, distributions on the Series A Preferred Units to preferred unitholders are cumulative from the date of original issue and are payable quarterly in arrears, when, as and if declared by the board of directors of the General Partner. At any time on or after April 30, 2018, the Series A Preferred Units may be redeemed by the Partnership at a redemption price of $25.00 per unit plus an amount equal to all accumulated and unpaid distributions to the date of redemption. These units are listed on the New York Stock Exchange.
