NUSTAR ENERGY L.P. AND SUBSIDIARIES

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. ORGANIZATION AND BASIS OF PRESENTATION

Organization and Operations

NuStar Energy L.P. (NuStar Energy) (NYSE: NS) is a publicly held Delaware limited partnership engaged in the transportation of petroleum products and anhydrous ammonia, the terminalling and storage of petroleum products and the marketing of petroleum products. Unless otherwise indicated, the terms “NuStar Energy,” “the Partnership,” “we,” “our” and “us” are used in this report to refer to NuStar Energy L.P., to one or more of our consolidated subsidiaries or to all of them taken as a whole. NuStar GP Holdings, LLC (NuStar GP Holdings) (NYSE: NSH) owns our general partner, Riverwalk Logistics, L.P., and owns a 15.0% total interest in us as of September 30, 2015.

We conduct our operations through our subsidiaries, primarily NuStar Logistics, L.P. (NuStar Logistics) and NuStar Pipeline Operating Partnership L.P. (NuPOP). We have three business segments: pipeline, storage and fuels marketing.

Basis of Presentation

These unaudited condensed consolidated financial statements include the accounts of the Partnership and subsidiaries in which the Partnership has a controlling interest. Noncontrolling interests are separately disclosed on the financial statements. Inter-partnership balances and transactions have been eliminated in consolidation. We account for investments in joint ventures using the equity method of accounting.

These unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and with the instructions to the Quarterly Report on Form 10-Q and Article 10 of Regulation S-X of the Securities Exchange Act of 1934. Accordingly, they do not include all of the information and notes required by GAAP for complete consolidated financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included, and all disclosures are adequate. All such adjustments are of a normal recurring nature unless disclosed otherwise. Financial information for the three and nine months ended September 30, 2015 and 2014 included in these Condensed Notes to Consolidated Financial Statements is derived from our unaudited condensed consolidated financial statements. Operating results for the three and nine months ended September 30, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015. The consolidated balance sheet as of December 31, 2014 has been derived from the audited consolidated financial statements as of that date. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2014.

New Accounting Pronouncements

In September 2015, the Financial Accounting Standards Board (FASB) issued amended guidance for business combinations that eliminates the requirement to restate prior period financial statements for measurement period adjustments. The new guidance requires that the cumulative impact of a measurement period adjustment be recognized in the reporting period in which the adjustment is identified. The changes are effective for annual and interim periods beginning after December 15, 2015, and early adoption is permitted for financial statements that have not been issued. We will adopt these provisions January 1, 2016, and we do not expect the amended guidance to have a material impact on our financial position, results of operations or disclosures.

In July 2015, the FASB issued amended guidance that requires inventory to be measured at the lower of cost or net realizable value. The changes are effective for annual and interim periods beginning after December 15, 2016, and early adoption is permitted. We will adopt these provisions January 1, 2017, and we do not expect the amended guidance to have a material impact on our financial position, results of operations or disclosures.

In April 2015, the FASB issued amended guidance for the presentation of debt issuance costs. Under the amended guidance, debt issuance costs will be presented on the balance sheet as a deduction from the carrying value of the associated debt liability. In August 2015, the FASB issued amended guidance that would allow debt issuance costs related to line-of-credit agreements to continue to be presented as an asset on the balance sheet. The changes are effective for annual and interim periods beginning after December 15, 2015, and retrospective application is required. Early adoption is permitted. We will adopt these provisions January 1, 2016, and we do not expect the amended guidance to have a material impact on our financial position, results of operations or disclosures.

NUSTAR ENERGY L.P. AND SUBSIDIARIES

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

In February 2015, the FASB issued new consolidation guidance that modifies the criterion involved in a reporting organization’s evaluation of whether certain legal entities are subject to consolidation under the standard. The standard is effective for public companies for annual and interim reporting periods beginning after December 15, 2015, using one of two retrospective transition methods. Early adoption is permitted. We will adopt these provisions January 1, 2016, and we do not expect the guidance to have a material impact on our financial position, results of operations or disclosures.

In May 2014, the FASB and the International Accounting Standards Board jointly issued a comprehensive new revenue recognition standard. In August 2015, the FASB deferred the effective date by one year. The standard is now effective for public entities for annual and interim periods beginning after December 15, 2017, using one of two retrospective transition methods. Early adoption is permitted, but not before the original effective date. We are currently assessing the impact of this new guidance on our financial statements and disclosures, and we have not yet selected a transition method.

2. ACQUISITIONS AND DISPOSITIONS

Acquisitions

Linden Acquisition. On January 2, 2015, we acquired full ownership of ST Linden Terminal, LLC (Linden), which owns a refined products terminal in Linden, NJ with 4.3 million barrels of storage capacity (the Linden Acquisition). Linden is located on a 44-acre facility that provides deep-water terminalling capabilities in the New York Harbor and primarily stores petroleum products, including gasoline, jet fuel and fuel oils. Prior to the Linden Acquisition, Linden operated as a joint venture between us and Linden Holding Corp, with each party owning 50%.

In connection with the Linden Acquisition, we ceased applying the equity method of accounting and consolidated Linden, which is included in our storage segment. The condensed consolidated statements of comprehensive income include the results of operations for Linden commencing on January 2, 2015. On the acquisition date, we remeasured our existing 50% equity investment in Linden to its fair value of $128.0 million and we recognized a gain of $56.3 million in “Other income (expense), net” in the condensed consolidated statements of comprehensive income for the nine months ended September 30, 2015. We estimated the fair value using a market approach, which estimates the enterprise value based on an earnings multiple. We funded the acquisition with borrowings under our revolving credit agreement. The acquisition complements our existing storage operations, and having sole ownership of Linden strengthens our presence in the New York Harbor and the East Coast market.

We accounted for the Linden Acquisition using the acquisition method. The purchase price has been allocated based on the estimated fair values of the individual assets acquired and liabilities assumed at the date of the acquisition. The purchase price allocation was as follows (in thousands of dollars):

Cash paid for the Linden Acquisition	$	142,500
Fair value of liabilities assumed	22,865
Consideration	165,365
Acquisition date fair value of previously held equity interest	128,000
Total	$	293,365
Current assets	$	1,746
Property, plant and equipment	134,484
Goodwill	86,975
Intangible assets (a)	70,050
Other long-term assets	110
Purchase price allocation	$	293,365

(a) Intangible assets primarily consist of customer contracts and relationships and are being amortized over 10 years.

Dispositions

Discontinued Operations. In January 2015, we sold our terminal in Alamogordo, NM with storage capacity of 0.1 million barrels for proceeds of $1.1 million.We classified the associated property, plant and equipment as “Assets held for sale” on the consolidated balance sheet as of December 31, 2014. In 2014, we divested our terminals in Mobile, AL, Wilmington, NC and Dumfries, VA and our 75% interest in our facility in Mersin, Turkey (the Turkey Sale). We recognized a gain of $3.7 million on the Turkey Sale for the three and nine months ended September 30, 2014. We presented the results of operations for those

NUSTAR ENERGY L.P. AND SUBSIDIARIES

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

facilities as discontinued operations. We allocated interest expense of $0.1 million and $0.8 million for the three and nine months ended September 30, 2014, respectively, to discontinued operations based on the ratio of net assets discontinued to consolidated net assets.

The following table summarizes the results from discontinued operations:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2015		2014		2015		2014
	(Thousands of Dollars)
Revenues	$	—	$	276	$	208	$	3,456
Income (loss) before income tax expense	$	—	$	2,831	$	774	$	(2,316	)

2014 Asphalt Sale. On February 26, 2014, we sold our remaining 50% ownership interest in NuStar Asphalt LLC to Lindsay Goldberg LLC (Lindsay Goldberg), a private investment firm (the 2014 Asphalt Sale). Effective February 27, 2014, NuStar Asphalt LLC changed its name to Axeon Specialty Products LLC (Axeon). Lindsay Goldberg now owns 100% of Axeon. As a result of the 2014 Asphalt Sale, we ceased applying the equity method of accounting.

3. INVENTORIES

Inventories consisted of the following:

	September 30, 2015		December 31, 2014
	(Thousands of Dollars)
Crude oil	$	2,326	$	3,527
Finished products	42,721		43,206
Materials and supplies	8,829		8,980
Total	$	53,876	$	55,713

4. DEBT

Revolving Credit Agreement

During the nine months ended September 30, 2015, the balance under our $1.5 billionfive-year revolving credit agreement (the Revolving Credit Agreement) increased by $306.6 million, which we used for general partnership purposes and to fund a portion of strategic capital expenditures, including the Linden Acquisition. The Revolving Credit Agreement matures on October 29, 2019 and bears interest, at our option, based on an alternative base rate, a LIBOR-based rate or a EURIBOR-based rate. The interest rate on the Revolving Credit Agreement is subject to adjustment if our debt rating is downgraded (or upgraded) by certain credit rating agencies. As of September 30, 2015, our weighted-average interest rate was 2.0% and we had $908.1 million outstanding.

The Revolving Credit Agreement contains customary restrictive covenants, such as limitations on indebtedness, liens, mergers, asset transfers and certain investing activities. In addition, the Revolving Credit Agreement requires us to maintain, as of the end of each rolling period of four consecutive fiscal quarters, a consolidated debt coverage ratio (consolidated debt to consolidated EBITDA, each as defined in the Revolving Credit Agreement) not to exceed 5.00-to-1.00. If we consummate one or more acquisitions for an aggregate net consideration of at least $50.0 million, the maximum consolidated debt coverage ratio will increase to 5.50-to-1.00 for two rolling periods. The requirement not to exceed a maximum consolidated debt coverage ratio may limit the amount we can borrow under the Revolving Credit Agreement to an amount less than the total amount available for borrowing. As of September 30, 2015, our consolidated debt coverage ratio was 4.4x, and we had $561.0 million available for borrowing.

Gulf Opportunity Zone Revenue Bonds

In 2008, 2010 and 2011, the Parish of St. James, Louisiana issued, pursuant to the Gulf Opportunity Zone Act of 2005, tax-exempt revenue bonds (the GoZone Bonds) associated with our St. James, Louisiana terminal expansions. The GoZone Bonds bear interest based on a weekly tax-exempt bond market interest rate, and interest is paid monthly. The weighted-average interest rate was 0.1% as of September 30, 2015. Following the issuance, the proceeds were deposited with a trustee and are disbursed to us upon our request for reimbursement of expenditures related to our St. James terminal expansion. We include the

NUSTAR ENERGY L.P. AND SUBSIDIARIES

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

amount remaining in trust in “Other long-term assets, net,” and we include the amount of bonds issued in “Long-term debt” on the consolidated balance sheets. For the nine months ended September 30, 2015, we received $13.6 million from the trustee. As of September 30, 2015, the amount remaining in trust totaled $57.9 million.

Receivables Financing Agreement

On June 15, 2015, NuStar Energy L.P. and NuStar Finance LLC (NuStar Finance), a newly formed special purpose entity and wholly owned subsidiary of NuStar Logistics, entered into a $125.0 million receivables financing agreement with third-party lenders (the Receivables Financing Agreement) and agreements with certain of NuStar Energy’s wholly owned subsidiaries (collectively with the Receivables Financing Agreement, the Securitization Program). Under the Securitization Program, certain of NuStar Energy’s wholly owned subsidiaries, NuStar Logistics, NuPOP, NuStar Energy Services, Inc. and NuStar Supply & Trading LLC (collectively, the Originators), sell their accounts receivable to NuStar Finance on an ongoing basis, and NuStar Finance provides the newly acquired accounts receivable as collateral for its revolving borrowings under the Receivables Financing Agreement. The maximum amount available for borrowing by NuStar Finance under the Receivables Financing Agreement is $125.0 million, with an option for NuStar Finance to request an increase of up to $75.0 million from the lenders (for aggregate total borrowings not to exceed $200.0 million). The amount available for borrowing is based on the availability of eligible receivables and other customary factors and conditions. The Securitization Program contains various customary affirmative and negative covenants and default, indemnification and termination provisions, and the Receivables Financing Agreement provides for acceleration of amounts owed upon the occurrence of certain specified events.

Borrowings by NuStar Finance under the Receivables Financing Agreement bear interest at either the applicable commercial paper rate or the applicable bank rate, each as defined under the Receivables Financing Agreement. The Securitization Program has an initial termination date of June 15, 2018, with the option to renew for additional 364-day periods thereafter. As of September 30, 2015, $98.9 million of our accounts receivable are included in the Securitization Program. The amount of borrowings outstanding under the Receivables Financing Agreement totaled $56.9 million as of September 30, 2015, which is included in “Long-term debt” on the consolidated balance sheet.

NuStar Finance’s sole business consists of purchasing such receivables and providing them as collateral under the Securitization Program. NuStar Finance is a separate legal entity and the assets of NuStar Finance, including these accounts receivable, are not available to satisfy the claims of creditors of NuStar Energy, the Originators or their affiliates.

5. COMMITMENTS AND CONTINGENCIES

Contingencies

We have contingent liabilities resulting from various litigation, claims and commitments. We record accruals for loss contingencies when losses are considered probable and can be reasonably estimated. Legal fees associated with defending the Partnership in legal matters are expensed as incurred. As of September 30, 2015, we have accrued $4.2 million for contingent losses. The amount that will ultimately be paid may differ from the recorded accruals, and the timing of such payments is uncertain. In addition, due to the inherent uncertainty of litigation, there can be no assurance that the resolution of any particular claim or proceeding would not have a material adverse effect on our results of operations, financial position or liquidity.

6. FAIR VALUE MEASUREMENTS

We segregate the inputs used in measuring fair value into three levels: Level 1, defined as observable inputs such as quoted prices for identical assets or liabilities in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable, such as quoted prices for similar assets or liabilities in active markets or quoted prices for identical assets or liabilities in markets that are not active; and Level 3, defined as unobservable inputs in which little or no market data exists. We consider counterparty credit risk and our own credit risk in the determination of all estimated fair values.

Product Imbalances.We value our assets and liabilities related to product imbalances using quoted market prices in active markets as of the reporting date. Therefore, we include these product imbalances in Level 1 of the fair value hierarchy.

Interest Rate Swaps.We estimate the fair value of our forward-starting interest rate swaps using discounted cash flows, which use observable inputs such as time to maturity and market interest rates. Therefore, we include these interest rate swaps in Level 2 of the fair value hierarchy.

Commodity Derivatives.We base the fair value of certain of our commodity derivative instruments on quoted prices on an exchange; accordingly, we include these items in Level 1 of the fair value hierarchy. We also have derivative instruments for which we determine fair value using industry pricing services and other observable inputs, such as quoted prices on an exchange for similar derivative instruments. Therefore, we include these derivative instruments in Level 2 of the fair value hierarchy. See Note 7 for a discussion of our derivative instruments.

Guarantees. We provide credit support, such as guarantees, letters of credit and cash collateral, as applicable, of up to $150.0 million to Axeon. As of September 30, 2015 and December 31, 2014, we provided guarantees mainly for commodity purchases, lease obligations and certain utilities for Axeon with an aggregate maximum potential exposure of $55.9 million and $25.3 million, respectively, and two guarantees that do not specify a maximum amount. A majority of these guarantees have no expiration date. We estimated the fair value of guarantees we have issued on behalf of Axeon considering the probability of default by Axeon and an estimate of the amount we would be obligated to pay under the guarantees at the time of default based on the guarantees outstanding as of September 30, 2015 and December 31, 2014. Our estimate of the fair value is based on significant inputs not observable in the market and thus falls within Level 3 of the fair value hierarchy.

The following table summarizes the activity in our Level 3 liabilities:

	Nine Months Ended September 30, 2015
	(Thousands of Dollars)
Beginning balance	$	580
Adjustments to guarantee liability	706
Ending balance	$	1,286

Fair Value of Financial Instruments

We recognize cash equivalents, receivables, note receivables, payables and debt in our consolidated balance sheets at their carrying amounts. The fair values of these financial instruments, except for the $190.0 million term loan to Axeon (the Axeon Term Loan) and long-term debt, approximate their carrying amounts. The estimated fair value and carrying amounts of the long-term debt and the Axeon Term Loan were as follows:

	September 30, 2015				December 31, 2014
	Fair Value		Carrying Amount		Fair Value		Carrying Amount
	(Thousands of Dollars)
Long-term debt	$	3,073,330	$	3,109,359	$	2,764,242	$	2,749,452
Axeon Term Loan	$	169,607	$	169,941	$	164,386	$	169,235

We estimated the fair value of our publicly-traded senior notes based upon quoted prices in active markets; therefore, we determined that the fair value of our publicly-traded senior notes falls in Level 1 of the fair value hierarchy. For our other debt, for which a quoted market price is not available, we estimated the fair value using a discounted cash flow analysis using current incremental borrowing rates for similar types of borrowing arrangements and determined that the fair value falls in Level 2 of the fair value hierarchy.

We estimated the fair value of the Axeon Term Loan using discounted cash flows, which use observable inputs such as time to maturity and market interest rates, and determined the fair value falls in Level 2 of the fair value hierarchy.

As of September 30, 2015, the carrying amount of the receivable for the Axeon Term Loan is $169.9 million, consisting of the following: (i) the outstanding principal amount from the Axeon Term Loan of $190.0 million; (ii) plus the fair value of guarantees of $1.3 million as of September 30, 2015; and (iii) less equity losses from our investment in Axeon of $21.3 million incurred prior to the 2014 Asphalt Sale and after the carrying value of our equity investment in Axeon was reduced to zero. The carrying value of the Axeon Term Loan is included in “Other long-term assets, net” on the consolidated balance sheets. We review the financial information of Axeon monthly for possible credit loss indicators. Axeon failed to make a scheduled principal payment by September 30, 2015, which will increase the interest rate until Axeon makes the payment.

7. DERIVATIVES AND RISK MANAGEMENT ACTIVITIES

We utilize various derivative instruments to manage our exposure to interest rate risk and commodity price risk. Our risk management policies and procedures are designed to monitor interest rates, futures and swap positions and over-the-counter positions, as well as physical commodity volumes, grades, locations and delivery schedules, to help ensure that our hedging activities address our market risks. Our risk management committee oversees our trading controls and procedures and certain aspects of commodity and trading risk management. Our risk management committee also reviews all new commodity and trading risk management strategies in accordance with our risk management policy, as approved by our board of directors.

Interest Rate Risk

We are a party to certain interest rate swap agreements to manage our exposure to changes in interest rates. During the nine months ended September 30, 2015, we entered into forward-starting interest rate swap agreements with an aggregate notional amount of $450.0 million. Under the terms of the swaps, we pay a fixed rate and receive a rate based on three month USD LIBOR. We entered into these swaps in order to hedge the risk of changes in the interest payments attributable to changes in the benchmark interest rate during the period from the effective date of the swap to the issuance of the forecasted debt. These swaps qualified, and we designated them, as cash flow hedges of future interest payments associated with forecasted debt issuances in 2018 and 2020. We record the effective portion of mark-to-market adjustments as a component of “Accumulated other comprehensive income” (AOCI), and the amount in AOCI will be recognized in “Interest expense, net” as the forecasted interest payments occur or if the interest payments are probable not to occur. We had no forward-starting interest rate swap agreements as of December 31, 2014.

Commodity Price Risk

We are exposed to market risks related to the volatility of crude oil and refined product prices. In order to reduce the risk of commodity price fluctuations with respect to our crude oil and finished product inventories and related firm commitments to purchase and/or sell such inventories, we utilize commodity futures and swap contracts, which qualify and we designate as fair value hedges. Derivatives that are intended to hedge our commodity price risk, but fail to qualify as fair value or cash flow hedges, are considered economic hedges, and we record associated gains and losses in net income. The volume of commodity contracts is based on open derivative positions and represents the combined volume of our long and short open positions on an absolute basis, which totaled 6.1 millionbarrels and 4.7 million barrels as of September 30, 2015 and December 31, 2014, respectively. The fair values of our derivative instruments included in our consolidated balance sheets were as follows:

Allocations of Net Income

Our partnership agreement, as amended, sets forth the calculation to be used to determine the amount and priority of cash distributions that the common unitholders and the general partner will receive. The partnership agreement also contains provisions for the allocation of net income and loss to the unitholders and the general partner. For purposes of maintaining partner capital accounts, the partnership agreement specifies that items of income and loss shall be allocated among the partners in accordance with their respective percentage interests. Normal allocations according to percentage interests are made after giving effect to priority income allocations, if any, in an amount equal to incentive cash distributions allocated 100% to the general partner.

The following table details the calculation of net income applicable to the general partner:

	Three Months Ended September 30,						Nine Months Ended September 30,

10. NET INCOME PER UNIT

We have identified the general partner interest and incentive distribution rights as participating securities and use the two-class method when calculating the net income per unit applicable to limited partners, which is based on the weighted-average number of common units outstanding during the period. Basic and diluted net income per unit applicable to limited partners are the same because we have no potentially dilutive securities outstanding.

The following table details the calculation of earnings per unit:

12. SEGMENT INFORMATION

Our reportable business segments consist of pipeline, storage and fuels marketing. Our segments represent strategic business units that offer different services and products. We evaluate the performance of each segment based on its respective operating income, before general and administrative expenses and certain non-segmental depreciation and amortization expense. General and administrative expenses are not allocated to the operating segments since those expenses relate primarily to the overall management at the entity level. Our principal operations include the transportation of petroleum products and anhydrous ammonia, the terminalling and storage of petroleum products and the marketing of petroleum products. Intersegment revenues result from storage agreements with wholly owned subsidiaries of NuStar Energy at lease rates consistent with rates charged to third parties for storage.

OVERVIEW

NuStar Energy L.P. (NuStar Energy) (NYSE: NS) is engaged in the transportation of petroleum products and anhydrous ammonia, the terminalling and storage of petroleum products and the marketing of petroleum products. Unless otherwise indicated, the terms “NuStar Energy,” “the Partnership,” “we,” “our” and “us” are used in this report to refer to NuStar Energy L.P., to one or more of our consolidated subsidiaries or to all of them taken as a whole. NuStar GP Holdings, LLC (NuStar GP Holdings) (NYSE: NSH) owns our general partner, Riverwalk Logistics, L.P., and owns a 15.0% total interest in us as of September 30, 2015. Our Management’s Discussion and Analysis of Financial Condition and Results of Operations is presented in seven sections:

• Overview

• Results of Operations

• Trends and Outlook

• Liquidity and Capital Resources

• Related Party Transactions

• Critical Accounting Policies

• New Accounting Pronouncements

Acquisitions and Dispositions

Linden Acquisition. On January 2, 2015, we acquired full ownership of ST Linden Terminal, LLC (Linden), which owns a refined products terminal in Linden, NJ with 4.3 million barrels of storage capacity (the Linden Acquisition). Linden is located on a 44-acre facility that provides deep-water terminalling capabilities in the New York Harbor and primarily stores petroleum products, including gasoline, jet fuel and fuel oils. Prior to the Linden Acquisition, Linden operated as a joint venture between us and Linden Holding Corp, with each party owning 50%.

In connection with the Linden Acquisition, we ceased applying the equity method of accounting and consolidated Linden, which is included in our storage segment. The condensed consolidated statements of comprehensive income include the results of operations for Linden commencing on January 2, 2015. On the acquisition date, we remeasured our existing 50% equity investment in Linden to its fair value of $128.0 million and we recognized a gain of $56.3 million in “Other income (expense), net” in the condensed consolidated statements of comprehensive income for the nine months ended September 30, 2015. Please refer to Note 2 of the Condensed Notes to Consolidated Financial Statements in Item 1. “Financial Statements” for a discussion of the Linden Acquisition.

Discontinued Operations.In January 2015, we sold our terminal in Alamogordo, NM with storage capacity of 0.1 million barrels for proceeds of $1.1 million. In 2014, we divested our terminals in Mobile, AL, Wilmington, NC and Dumfries, VA and our 75% interest in our facility in Mersin, Turkey (the Turkey Sale). We presented the results of operations for those facilities as discontinued operations.

28

2014 Asphalt Sale. On February 26, 2014, we sold our remaining 50% ownership interest in NuStar Asphalt LLC to Lindsay Goldberg LLC (Lindsay Goldberg), a private investment firm (the 2014 Asphalt Sale). Effective February 27, 2014, NuStar Asphalt LLC changed its name to Axeon Specialty Products LLC (Axeon). Lindsay Goldberg now owns 100% of Axeon. As a result of the 2014 Asphalt Sale, we ceased applying the equity method of accounting, and we ceased reporting transactions between us and Axeon as related party transactions in our consolidated financial statements.

Operations

We conduct our operations through our subsidiaries, primarily NuStar Logistics, L.P. (NuStar Logistics) and NuStar Pipeline Operating Partnership L.P. (NuPOP). Our operations consist of three reportable business segments: pipeline, storage and fuels marketing.

Pipeline. We own refined product pipelines covering approximately 5,500 miles of pipelines, which consist of Central West System refined product pipelines, the East Pipeline and the North Pipeline. The East and North Pipelines have storage capacity of approximately 6.0 million barrels. In addition, we own a 2,000 mile anhydrous ammonia pipeline (the Ammonia Pipeline) and 1,190 miles of Central West System crude oil pipelines including approximately 4.0 million barrels of storage capacity. We charge tariffs on a per barrel basis for transporting refined products, crude oil and other feedstocks in our refined product and crude oil pipelines and on a per ton basis for transporting anhydrous ammonia in the Ammonia Pipeline.

Storage. We own terminals and storage facilities in the United States, Canada, Mexico, the Netherlands, including St. Eustatius in the Caribbean, and the United Kingdom providing approximately 83.0 million barrels of storage capacity. Revenues for the storage segment include fees for tank storage agreements, whereby a customer agrees to pay for a certain amount of storage in a tank over a period of time (storage lease revenues), and throughput agreements, whereby a customer pays a fee per barrel for volumes moving through our terminals for which we charge additional fees (throughput revenues).

Fuels Marketing. Within our fuels marketing operations, we purchase crude oil and refined petroleum products for resale. The results of operations for the fuels marketing segment depend largely on the margin between our cost and the sales prices of the products we market. Therefore, the results of operations for this segment are more sensitive to changes in commodity prices compared to the results of operations of the pipeline and storage segments. We enter into derivative contracts to attempt to mitigate the effects of commodity price fluctuations.

The following factors affect the results of our operations:

• company-specific factors, such as facility integrity issues and maintenance requirements that impact the throughput rates of our assets;

• seasonal factors that affect the demand for products transported by and/or stored in our assets and the demand for products we sell;

• industry factors, such as changes in the prices of petroleum products that affect demand and operations of our competitors;

• factors such as commodity price volatility that impact our fuels marketing segment; and

• other factors, such as refinery utilization rates and maintenance turnaround schedules, that impact the operations of refineries served by our pipeline and storage assets.

Pipeline

Revenues increased $5.9 million and throughputs increased 22,512 barrels per day for the three months ended September 30, 2015, compared to the three months ended September 30, 2014, primarily due to:

• an increase in revenues of $2.7 million and an increase in throughputs of 4,103 barrels per day on the Ammonia Pipeline, due to increased long-haul deliveries, the annual index adjustment in July 2015 and higher volumes shipped as a result of low inventory levels and in anticipation of a heavy fall application season;

• an increase in revenues of $2.2 million and an increase in throughputs of 6,598 barrels per day on our McKee systems due to higher demand in markets served by those pipelines;

• an increase in revenues of $1.2 million and an increase in throughputs of 8,600 barrels per day on our Eagle Ford System, mainly due to the increase of throughputs to a customer’s refinery in preparation for planned maintenance; and

• an increase in revenues of $0.4 million and an increase in throughputs of 8,113 barrels per day on our Burgos pipeline as a result of a project completed in 2015.

The increases in pipeline revenues and throughputs were partially offset by a decrease in revenues of $2.0 million and a decrease in throughputs of 6,630 barrels per day due to turnarounds at refineries served by the East Pipeline and maintenance downtime on a portion of the East Pipeline.

Operating expenses increased $1.2 million for the three months ended September 30, 2015, compared to the three months ended September 30, 2014, primarily due to higher maintenance and regulatory expenses for certain Eagle Ford System pipelines and Central West System refined product pipelines.

Depreciation and amortization expense increased $1.8 million for the three months ended September 30, 2015, compared to the three months ended September 30, 2014, mainly due to the completion of various projects on the Eagle Ford System.

Storage

Throughput revenues decreased $0.4 million and throughputs decreased 41,722 barrels per day for the three months ended September 30, 2015, compared to the three months ended September 30, 2014, primarily due to an unscheduled shutdown at the refinery served by our Texas City crude oil storage tank facility.

Storage lease revenues increased $18.6 million for the three months ended September 30, 2015, compared to the three months ended September 30, 2014, primarily due to:

• an increase of $10.8 million as a result of the Linden Acquisition; and

• an increase of $6.0 million at our domestic terminal facilities, due to increased throughput and related handling fees, storage rate escalations, new customers and increased reimbursable revenues, mainly at our Texas City and asphalt terminal facilities.

Operating expenses increased $5.3 million for the three months ended September 30, 2015, compared to the three months ended September 30, 2014, primarily due to:

• an increase of $3.8 million as a result of the Linden Acquisition; and

• an increase of $1.9 million in reimbursable expenses, mainly at our Texas City and Point Tupper terminal facilities.

The increases in storage operating expenses were partially offset by a decrease of $1.4 million in contract services, mainly at our St. James terminal facility due to a reduction in dock and rail labor costs.

Depreciation and amortization expense increased $2.3 million for the three months ended September 30, 2015, compared to the three months ended September 30, 2014, mainly due to the addition of assets associated with the Linden Acquisition.

Fuels Marketing

We recorded a segment operating loss of $1.8 million for the three months ended September 30, 2015, compared to segment operating income of $7.5 million for the three months ended September 30, 2014, primarily due to lower product margins in our bunker fuel operations.

Consolidation and Intersegment Eliminations

Revenue and operating expense eliminations primarily relate to storage fees charged to the fuels marketing segment by the storage segment. Cost of product sales eliminations represent expenses charged to the fuels marketing segment for costs associated with inventory that are expensed once the inventory is sold.

32

General

General and administrative expenses decreased $1.3 million for the three months ended September 30, 2015, compared to the three months ended September 30, 2014, primarily as a result of lower compensation expense associated with our long-term incentive plans, which fluctuates with our unit price. The lower compensation expense was partially offset by increased salaries and wages mainly due to increased headcount and higher employee benefit costs.

Equity in earnings of joint ventures for the three months ended September 30, 2014 relates to our equity investment in Linden prior to the Linden Acquisition.

Other income (expense), net changed by $3.2 million for the three months ended September 30, 2015, compared to the three months ended September 30, 2014, mainly due to gains associated with the sale of assets in 2015 and changes in foreign exchange rates related to our foreign subsidiaries.

Income from discontinued operations for the three months endedSeptember 30, 2014 includes a gain of $3.7 million related to the Turkey Sale.

Pipeline

Revenues increased $31.8 million and throughputs increased 73,431 barrels per day for the nine months ended September 30, 2015, compared to the nine months ended September 30, 2014, primarily due to:

• an increase in revenues of $21.4 million and an increase in throughputs of 57,108 barrels per day on our Eagle Ford System, primarily resulting from completion of expansion projects that increased our overall capacity; and

• an increase in revenues of $10.3 million and an increase in throughputs of 22,232 barrels per day mainly as aresult of a turnaround during the first quarter of 2014 at the refinery served by our McKee systems.

The increases in pipeline revenues and throughputs were partially offset by a decrease in revenues of $5.0 million and a decrease in throughputs of 10,309 barrels per day due to turnarounds at refineries served by the East Pipeline, unfavorable pricing differentials in markets served by the East Pipeline and heavy rainfall that negatively affected demand related to the planting season.

Operating expenses increased $3.5 million for the nine months ended September 30, 2015, compared to the nine months ended September 30, 2014, primarily due to an increase in salaries and wages of $1.9 million resulting from higher compensation accruals. In addition, ad valorem taxes increased $1.1 million mainly on our East Pipeline and North Pipeline, as a result of changes in valuations.

Depreciation and amortization expense increased $5.2 million for the nine months ended September 30, 2015, compared to the nine months ended September 30, 2014, mainly due to the completion of expansion projects.

Storage

Throughput revenues increased $7.2 million and throughputs increased 26,454 barrels per day for the nine months ended September 30, 2015, compared to the nine months ended September 30, 2014, primarily due to:

• an increase in revenues of $3.5 million and an increase in throughputs of 38,294 barrels per day at our Corpus Christi North Beach terminal due to an increase in Eagle Ford Shale crude oil being shipped to Corpus Christi and the completion of related expansion projects;

• an increase in revenues of $2.8 million and an increase in throughputs of 17,089 barrels per day as a result of turnarounds during the first quarter of 2014 at the refineries served by our Benicia crude oil storage tank facility and McKee system terminals; and

• an increase in revenues of $1.6 million and an increase in throughputs of 4,777 barrels per day at our Corpus Christi System and Paulsboro terminals due to increased demand.

The increases in storage throughput revenues and throughputs were partially offset by a decrease in revenues of $1.0 million and a decrease in throughputs of 29,826 barrels per day as a result of a turnaround during the first quarter of 2015 at the refinery served by our Texas City crude oil storage tank facility.

Storage lease revenues increased $41.4 million for the nine months ended September 30, 2015, compared to the nine months ended September 30, 2014, primarily due to:

• an increase of $30.9 million as a result of the Linden Acquisition;

• an increase of $11.6 million at our St. Eustatius terminal facility, mainly due to increased demand for storage and higher ancillary activity; and

• an increase of $5.7 million at our domestic terminal facilities, mainly due to storage rate escalations, new customers and increased reimbursable revenues at our Texas City and asphalt terminal facilities.

The increases in storage lease revenues were partially offset by a decrease of $6.9 million at our UK and Amsterdam terminal facilities, primarily due to the effect of foreign exchange rates.

Operating expenses increased $17.5 million for the nine months ended September 30, 2015, compared to the nine months ended September 30, 2014, primarily due to:

• an increase of $10.6 million as a result of the Linden Acquisition;

• an increase of $5.2 million in regulatory and maintenance expenses, mainly at our St. James and St. Eustatius terminal facilities; and

• an increase of $2.8 million associated with property taxes at our St. Eustatius terminal facility.

The increases in storage operating expenses were partially offset by a decrease of $3.0 million in contract services, mainly at our St. James terminal facility due to a reduction in dock and rail labor costs.

36

Depreciation and amortization expense increased $10.7 million for the nine months ended September 30, 2015, compared to the nine months ended September 30, 2014, mainly due to the assets associated with the Linden Acquisition.

Fuels Marketing

Segment operating income decreased $11.1 million for the nine months ended September 30, 2015, compared to the nine months ended September 30, 2014, primarily due to lower product margins from our refined product sales and fuel oil trading.

Consolidation and Intersegment Eliminations

Revenue and operating expense eliminations primarily relate to storage fees charged to the fuels marketing segment by the storage segment. Cost of product sales eliminations represent expenses charged to the fuels marketing segment for costs associated with inventory that are expensed once the inventory is sold.

General

General and administrative expenses increased $6.4 million for the nine months ended September 30, 2015, compared to the nine months ended September 30, 2014, primarily due to:

• an $8.2 million increase in salaries and wages mainly due to increased headcount and higher employee benefit costs;

• a $3.1 million increase as a result of the termination of a services agreement between Axeon and NuStar GP, LLC in June 2014, under which Axeon reimbursed us for certain corporate support services; and

• a $2.3 million increase in outside legal costs.

The increases in general and administrative expenses were partially offset by a decrease of $7.1 million in compensation expense associated with our long-term incentive plans, which fluctuates with our unit price.

Equity in earnings of joint ventures for the nine months ended September 30, 2014 primarily relates to our equity investment in Linden prior to the Linden Acquisition.

Interest expense, net decreased $2.2 million for the nine months ended September 30, 2015, compared to the nine months ended September 30, 2014, mainly due to increased interest income from our $190.0 million term loan to Axeon (the Axeon Term Loan) and higher capitalized interest resulting from increased capital projects. The decrease in interest expense, net was partially offset by increased interest costs associated with higher borrowings under our revolving credit agreement.

Other income, net increased $60.1 million for the nine months ended September 30, 2015, compared to the nine months ended September 30, 2014, mainly due to the $56.3 million gain associated with the Linden Acquisition.

For the nine months ended September 30, 2015, we recorded income from discontinued operations of $0.8 million, compared to a loss from discontinued operations of $2.3 million for the nine months ended September 30, 2014. Discontinued operations include the results of operations of certain storage assets that were divested in 2014 and the first quarter of 2015.

TRENDS AND OUTLOOK

Current Market Conditions

Since late 2014, the price of crude oil and refined products has declined significantly. This market presents challenges for crude oil producers, and many have reduced capital spending and drilling activity or begun to narrow their focus to assets in the most cost-advantaged regions. On the other hand, refiners benefit from lower crude prices, to the extent the lower feedstock price has been coupled with higher demand for certain refined products.

We believe we have minimal direct exposure to the risks associated with fluctuating commodity prices, due to the fact that most of our commercial contracts are long-term and require customers to agree to take-or-pay arrangements for committed storage or throughput capacity. In addition, we believe the diversity of services we provide, coupled with the fact that our assets are located in cost-advantaged regional markets across the country and around the world, serve to mitigate the short-term impact of low crude and refined products prices on our results of operations. However, a protracted period of depressed crude oil prices could have a negative impact on demand for some of our pipeline services in the Eagle Ford region and our associated future earnings.

We expect this lower commodity price environment to continue through the remainder of this year and the first half of 2016, but we expect to see a modest recovery in the back half of next year.

Pipeline Segment

We expect our pipeline segment to continue to benefit from pipeline expansion projects completed in 2014 and the first half of 2015 that increased our Eagle Ford System’s overall capacity. In addition, we expect the remainder of the year to benefit from the July 1, 2015 tariff increase on our pipelines subject to regulation by the Federal Energy Regulatory Commission (FERC). Although we expect our fourth quarter 2015 earnings to be lower than third quarter 2015 due to turnaround activity at some of our customers’ refineries and reduced throughput volumes on our Eagle Ford System due to lower domestic shale production, we expect our fourth quarter 2015 pipeline segment earnings to be comparable to the fourth quarter 2014. Further, we expect our full-year earnings for 2015 to exceed 2014 earnings, due to the benefit of increased capacity in our Eagle Ford System, as well as the FERC pipeline tariff increase.

Storage Segment

We expect storage segment earnings for the fourth quarter 2015 to exceed the fourth quarter 2014, but be lower than the third quarter 2015, due to several factors. Our storage segment should continue to benefit from the Linden Acquisition that we closed January 2015. We have also successfully renewed customer contracts at several of our terminal facilities. In addition, we expect to receive insurance proceeds in fourth quarter 2015 for Hurricane Sandy damage at our Linden terminal. However, we expect that the reduced throughput on our Eagle Ford System described above will also result in lower throughputs in the fourth quarter at our Corpus Christi North Beach terminal. We expect the full-year earnings for 2015 to exceed 2014 mainly due to the Linden Acquisition, favorable renewals of storage contracts at several of our terminal facilities and higher year-over-year throughputs at our Corpus Christi North Beach terminal.

We expect that our reliability capital spending in the last half of 2015 will significantly exceed the first half of 2015 due to required tank inspections and various other regulatory requirements mainly related to the storage segment.

Fuels Marketing Segment

We expect fourth quarter 2015 results for our fuels marketing segment to exceed the fourth quarter 2014 and the third quarter 2015. We expect full-year 2015 results in this segment to be lower than 2014 results mainly due to weaker margins across the segment. However, earnings in this segment, as in any margin-based business, are subject to many factors that can increase or reduce margins, which may cause the segment’s actual results to vary significantly from our forecast.

Our outlook for the partnership, both overall and for any of our segments, may change, as we base our expectations on our continuing evaluation of a number of factors, many of which are outside our control, including the price of crude oil, the state of the economy, changes to refinery maintenance schedules, demand for crude oil, refined products and anhydrous ammonia, demand for our transportation and storage services and changes in laws or regulations affecting our assets.

LIQUIDITY AND CAPITAL RESOURCES

Overview

Primary Cash Requirements. Our primary cash requirements are for distributions to our partners, working capital (including inventory purchases), debt service, capital expenditures, including reliability capital, a financing agreement with Axeon, acquisitions and operating expenses.

Our partnership agreement requires that we distribute all “Available Cash” to our partners each quarter, and this term is defined in the partnership agreement as cash on hand at the end of the quarter, plus certain permitted borrowings made subsequent to the end of the quarter, less cash reserves determined by our board of directors.

Sources of Funds. Each year, our objective is to fund our total annual reliability capital expenditures and distribution requirements with our net cash provided by operating activities during that year. If we do not generate sufficient cash from operations to meet that objective, we utilize other sources of cash flow, which in the past have primarily included borrowings under our revolving credit agreement, sales of non-strategic assets and, to the extent necessary, funds raised through equity or debt offerings under our shelf registration statements. We typically fund our strategic capital expenditures and acquisitions from external sources, primarily borrowings under our revolving credit agreement or funds raised through equity or debt offerings. However, our ability to raise funds by issuing debt or equity depends on many factors beyond our control. Our risk factors in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2014 describe the risks inherent to these sources of funding and the availability thereof.

During periods that our cash flow from operations is less than our distribution and reliability capital requirements, we may maintain our distribution level because we can utilize other sources of Available Cash, as provided in our partnership agreement, including borrowing under our revolving credit agreement and the proceeds from the sales of assets. Our risk factors in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2014 describe the risks inherent in our ability to maintain or grow the distribution.

Cash Requirements and Sources. For 2015, we currently expect to continue to produce cash from operations in excess of our distribution and reliability capital expenditures.

Cash Flows for the Nine Months Ended September 30, 2015 and 2014

The following table summarizes our cash flows from operating, investing and financing activities:

	Nine Months Ended September 30,
	2015			2014
	(Thousands of Dollars)
Net cash provided by (used in):
Operating activities	$	376,124		$	315,195
Investing activities	(377,435		)	(206,844		)
Financing activities	40,143			(184,046		)
Effect of foreign exchange rate changes on cash	(10,319		)	638
Net increase (decrease) in cash and cash equivalents	$	28,513		$	(75,057	)

Net cash provided by operating activities for the nine months ended September 30, 2015 was $376.1 million, compared to $315.2 million for the nine months ended September 30, 2014, primarily due to higher net income in 2015. In addition, our working capital decreased by $19.8 million for the nine months ended September 30, 2015, compared to $1.1 million for the nine months ended September 30, 2014.

For the nine months ended September 30, 2015, net cash provided by operating activities was used to fund our distributions and reliability capital expenditures. Proceeds from debt borrowings, net of repayments, combined with cash on hand, were used to fund our strategic capital expenditures, including the Linden Acquisition.

For the nine months ended September 30, 2014, net cash provided by operating activities was used to fund our distributions and our reliability capital expenditures. Proceeds from debt borrowings, net of repayments, combined with cash on hand and proceeds from the sales of assets, were used to fund strategic capital expenditures and advances to Axeon before the 2014 Asphalt Sale.

39

Revolving Credit Agreement

As of September 30, 2015, our consolidated debt coverage ratio could not exceed 5.00-to-1.00. The requirement not to exceed a maximum consolidated debt coverage ratio may limit the amount we can borrow under our revolving credit agreement to an amount less than the total amount available for borrowing. As of September 30, 2015, our consolidated debt coverage ratio was 4.4x, and we had $561.0 million available for borrowing. Letters of credit issued under our revolving credit agreement totaled $30.9 million as of September 30, 2015. Please refer to Note 4 of the Condensed Notes to Consolidated Financial Statements in Item 1. “Financial Statements” for a more detailed discussion on our revolving credit agreement.

LOC Agreement

In June 2015, we entered into a $100.0 million uncommitted letter of credit agreement, with a term of up to one year (LOC Agreement), to increase availability under our revolving credit agreement. Any letters of credit issued under the LOC Agreement will not reduce availability under our revolving credit agreement. As of September 30, 2015, we issued $46.8 million of letters of credit under the LOC Agreement.

Receivables Financing Agreement

On June 15, 2015, NuStar Energy L.P. and NuStar Finance LLC, a newly formed special purpose entity and wholly owned subsidiary of NuStar Logistics, entered into a $125.0 million receivables financing agreement with third-party lenders (the Receivables Financing Agreement) and agreements with certain of NuStar Energy’s wholly owned subsidiaries (collectively with the Receivables Financing Agreement, the Securitization Program). The amount available for borrowing is based on the availability of eligible receivables and other customary factors and conditions. The amount of borrowings outstanding under the Receivables Financing Agreement totaled $56.9 million as of September 30, 2015. Please refer to Note 4 of the Condensed Notes to Consolidated Financial Statements in Item 1. “Financial Statements” for a more detailed discussion.

Short-term Lines of Credit

As of September 30, 2015, we had two short-term line of credit agreements with an aggregate uncommitted borrowing capacity of up to $80.0 million. These agreements allow us to better manage the fluctuations in our daily cash requirements and minimize our excess cash balances. The interest rate and maturity vary and are determined at the time of the borrowing. We had $42.0 million outstanding under these short-term lines of credit as of September 30, 2015.

Shelf Registration Statement

On June 2, 2015, the Securities and Exchange Commission declared effective our shelf registration statement on Form S-3, which permits us to offer and sell NuStar Energy common units having an aggregate purchase price of up to $500.0 million (the Shelf Registration Statement).

On September 30, 2015, in connection with the Shelf Registration Statement, we entered into an Equity Distribution Agreement (the Equity Distribution Agreement) with various banks (each, a Manager, and collectively, the Managers). Under the Equity Distribution Agreement, we may from time to time sell NuStar Energy common units representing limited partner interests having an aggregate offering price of up to $500.0 million, using the Managers as our sales agents. Sales of common units will be made by means of ordinary brokers’ transactions on the New York Stock Exchange at market prices, in block transactions or as otherwise agreed by us and the Managers. Under the terms of the Equity Distribution Agreement, we may also sell common units to any Manager as principal for its own account at a price to be agreed upon at the time of sale.

Capital Requirements

Our operations require significant investments to maintain, upgrade or enhance the operating capacity of our existing assets. Our capital expenditures consist of:

• reliability capital expenditures, such as those required to maintain equipment reliability and safety; and

• strategic capital expenditures, such as those to expand and upgrade pipeline capacity or terminal facilities and to construct new pipelines, terminals and storage tanks. In addition, strategic capital expenditures may include acquisitions of pipelines, terminals or storage tank assets, as well as certain capital expenditures related to support functions.

During the nine months ended September 30, 2015, our reliability capital expenditures totaled $22.1 million, primarily related to dry-docking costs on one of our marine vessels and maintenance upgrade projects at our terminals. Strategic capital expenditures for the nine months ended September 30, 2015 totaled $364.7 million and were primarily related to the Linden Acquisition, projects associated with Eagle Ford Shale region in South Texas and the reactivation and conversion of our 200-mile pipeline between Mont Belvieu and Corpus Christi, TX.

40

During the nine months ended September 30, 2014, our reliability capital expenditures totaled $18.2 million and were primarily related to maintenance upgrade projects at our terminals. Strategic capital expenditures for the nine months ended September 30, 2014 totaled $211.3 million and were primarily related to projects associated with Eagle Ford Shale production in South Texas and the reactivation and conversion of our 200-mile pipeline between Mont Belvieu and Corpus Christi, TX.

For the full year 2015, we expect to incur approximately $465.0 million to $485.0 million of capital expenditures, including approximately $30.0 million to $40.0 million for reliability capital expenditures and $435.0 million to $445.0 million for strategic capital expenditures, including acquisitions. We continue to evaluate our capital budget and make changes as economic conditions warrant, and our actual capital expenditures for 2015 may increase or decrease from the budgeted amounts. We believe cash generated from operations, combined with other sources of liquidity previously described, will be sufficient to fund our capital expenditures in 2015, and our internal growth projects can be accelerated or scaled back depending on the condition of the capital markets.

Working Capital Requirements

Working capital requirements, mainly in our fuels marketing segment, may vary with the seasonality of demand and commodity prices for the products we market. This seasonality in demand and commodity prices affect our accounts receivable and accounts payable balances, which vary depending on the timing of payments.

Axeon Term Loan and Credit Support

We are a party to the Axeon Term Loan, and we provide credit support, such as guarantees, letters of credit and cash collateral, as applicable, of up to $150.0 million to Axeon. As of September 30, 2015, we provided guarantees for Axeon with an aggregate maximum potential exposure of $55.9 million, plus two guarantees to suppliers that do not specify a maximum amount, but for which we believe any amounts due would be minimal. As of September 30, 2015, we have also provided $69.3 million in letters of credit on behalf of Axeon. Please refer to Note 6 of the Condensed Notes to Consolidated Financial Statements in Item 1. “Financial Statements” for a discussion of the Axeon Term Loan and credit support.

41

Debt Obligations

As of September 30, 2015, we were a party to the following debt agreements:

• revolving credit agreement due October 29, 2019, with a balance of $908.1 million as of September 30, 2015;

• 7.65% senior notes due April 15, 2018 with a face value of $350.0 million; 4.80% senior notes due September 1, 2020 with a face value of $450.0 million; 6.75% senior notes due February 1, 2021 with a face value of $300.0 million; 4.75% senior notes due February 1, 2022 with a face value of $250.0 million; and 7.625% subordinated notes due January 15, 2043 with a face value of $402.5 million;

• $365.4 million Gulf Opportunity Zone Revenue Bonds due from 2038 to 2041;

• $80.0 million line of credit agreements with $42.0 million outstanding as of September 30, 2015; and

• Receivables Financing Agreement due June 15, 2018, with $56.9 million of borrowings outstanding as of September 30, 2015.

Management believes that, as of September 30, 2015, we are in compliance with all ratios and covenants contained in our debt instruments. A default under any of our debt instruments would be considered an event of default under all of our debt instruments. Please refer to Note 4 of the Condensed Notes to Consolidated Financial Statements in Item 1. “Financial Statements” for a more detailed discussion on certain of our debt agreements.

Interest Rate Swaps

We are a party to forward-starting interest rate swap agreements for the purpose of hedging interest rate risk. During the nine months ended September 30, 2015, we entered into forward-starting interest rate swap agreements with an aggregate notional amount of $450.0 million. We had no forward-starting interest rate swap agreements as of December 31, 2014. Please refer to Note 7 of the Condensed Notes to Consolidated Financial Statements in Item 1. “Financial Statements” for a more detailed discussion of our interest rate swaps.

Environmental, Health and Safety

We are subject to extensive federal, state and local environmental and safety laws and regulations, including those relating to the discharge of materials into the environment, waste management, pollution prevention measures, pipeline integrity and operator qualifications, among others. Because more stringent environmental and safety laws and regulations are continuously being enacted or proposed, the level of future expenditures required for environmental, health and safety matters is expected to increase.

Contingencies

We are subject to certain loss contingencies, the outcomes of which could have an adverse effect on our cash flows and results of operations, as further disclosed in Note 5 of the Condensed Notes to Consolidated Financial Statements in Item 1. “Financial Statements.”

RELATED PARTY TRANSACTIONS

Please refer to Note 8 of the Condensed Notes to Consolidated Financial Statements in Item 1. “Financial Statements” for a discussion of our related party transactions.

CRITICAL ACCOUNTING POLICIES

The preparation of financial statements in accordance with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Our critical accounting policies are disclosed in our Annual Report on Form 10-K for the year ended December 31, 2014.

NEW ACCOUNTING PRONOUNCEMENTS

Please refer to Note 1 of the Condensed Notes to Consolidated Financial Statements in Item 1. “Financial Statements” for a discussion of new accounting pronouncements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk

We manage our exposure to changing interest rates principally through the use of a combination of fixed-rate debt and variable-rate debt. In addition, we utilize forward-starting interest rate swap agreements to lock in the rate on the interest payments related to forecasted debt issuances. Borrowings under our variable rate debt expose us to increases in interest rates. During the nine months ended September 30, 2015, we entered into forward-starting interest rate swap agreements. Please refer to Note 7 of the Condensed Notes to Consolidated Financial Statements in Item 1. “Financial Statements” for a more detailed discussion of our interest rate swaps. The following tables present principal cash flows and related weighted-average interest rates by expected maturity dates for our long-term debt:

Commodity Price Risk

Since the operations of our fuels marketing segment expose us to commodity price risk, we enter into derivative instruments to attempt to mitigate the effects of commodity price fluctuations. The derivative instruments we use consist primarily of commodity futures and swap contracts. We have a risk management committee that oversees our trading policies and procedures and certain aspects of risk management. Our risk management committee also reviews all new risk management strategies in accordance with our risk management policy, as approved by our board of directors.

We record commodity derivative instruments in the consolidated balance sheets as assets or liabilities at fair value. We recognize mark-to-market adjustments for derivative instruments designated and qualifying as fair value hedges (Fair Value Hedges) and the related change in the fair value of the associated hedged physical inventory or firm commitment within “Cost of product sales.” For derivative instruments that have associated underlying physical inventory but do not qualify for hedge accounting (Economic Hedges and Other Derivatives), we record the mark-to-market adjustments in “Cost of product sales” or “Operating expenses.”

The commodity contracts disclosed below represent only those contracts exposed to commodity price risk at the end of the period. Please refer to Note 7 of Condensed Notes to Consolidated Financial Statement in Item 1. “Financial Statements” for the volume and related fair value of all commodity contracts.

Debt Disclosure [Abstract]

DEBT

DEBT

Revolving Credit Agreement

During the nine months ended September 30, 2015, the balance under our $1.5 billionfive-year revolving credit agreement (the Revolving Credit Agreement) increased by $306.6 million, which we used for general partnership purposes and to fund a portion of strategic capital expenditures, including the Linden Acquisition. The Revolving Credit Agreement matures on October 29, 2019 and bears interest, at our option, based on an alternative base rate, a LIBOR-based rate or a EURIBOR-based rate. The interest rate on the Revolving Credit Agreement is subject to adjustment if our debt rating is downgraded (or upgraded) by certain credit rating agencies. As of September 30, 2015, our weighted-average interest rate was 2.0% and we had $908.1 million outstanding.

The Revolving Credit Agreement contains customary restrictive covenants, such as limitations on indebtedness, liens, mergers, asset transfers and certain investing activities. In addition, the Revolving Credit Agreement requires us to maintain, as of the end of each rolling period of four consecutive fiscal quarters, a consolidated debt coverage ratio (consolidated debt to consolidated EBITDA, each as defined in the Revolving Credit Agreement) not to exceed 5.00-to-1.00. If we consummate one or more acquisitions for an aggregate net consideration of at least $50.0 million, the maximum consolidated debt coverage ratio will increase to 5.50-to-1.00 for two rolling periods. The requirement not to exceed a maximum consolidated debt coverage ratio may limit the amount we can borrow under the Revolving Credit Agreement to an amount less than the total amount available for borrowing. As of September 30, 2015, our consolidated debt coverage ratio was 4.4x, and we had $561.0 million available for borrowing.

Gulf Opportunity Zone Revenue Bonds

In 2008, 2010 and 2011, the Parish of St. James, Louisiana issued, pursuant to the Gulf Opportunity Zone Act of 2005, tax-exempt revenue bonds (the GoZone Bonds) associated with our St. James, Louisiana terminal expansions. The GoZone Bonds bear interest based on a weekly tax-exempt bond market interest rate, and interest is paid monthly. The weighted-average interest rate was 0.1% as of September 30, 2015. Following the issuance, the proceeds were deposited with a trustee and are disbursed to us upon our request for reimbursement of expenditures related to our St. James terminal expansion. We include the amount remaining in trust in “Other long-term assets, net,” and we include the amount of bonds issued in “Long-term debt” on the consolidated balance sheets. For the nine months ended September 30, 2015, we received $13.6 million from the trustee. As of September 30, 2015, the amount remaining in trust totaled $57.9 million.

Receivables Financing Agreement

On June 15, 2015, NuStar Energy L.P. and NuStar Finance LLC (NuStar Finance), a newly formed special purpose entity and wholly owned subsidiary of NuStar Logistics, entered into a $125.0 million receivables financing agreement with third-party lenders (the Receivables Financing Agreement) and agreements with certain of NuStar Energy’s wholly owned subsidiaries (collectively with the Receivables Financing Agreement, the Securitization Program). Under the Securitization Program, certain of NuStar Energy’s wholly owned subsidiaries, NuStar Logistics, NuPOP, NuStar Energy Services, Inc. and NuStar Supply & Trading LLC (collectively, the Originators), sell their accounts receivable to NuStar Finance on an ongoing basis, and NuStar Finance provides the newly acquired accounts receivable as collateral for its revolving borrowings under the Receivables Financing Agreement. The maximum amount available for borrowing by NuStar Finance under the Receivables Financing Agreement is $125.0 million, with an option for NuStar Finance to request an increase of up to $75.0 million from the lenders (for aggregate total borrowings not to exceed $200.0 million). The amount available for borrowing is based on the availability of eligible receivables and other customary factors and conditions. The Securitization Program contains various customary affirmative and negative covenants and default, indemnification and termination provisions, and the Receivables Financing Agreement provides for acceleration of amounts owed upon the occurrence of certain specified events.

Borrowings by NuStar Finance under the Receivables Financing Agreement bear interest at either the applicable commercial paper rate or the applicable bank rate, each as defined under the Receivables Financing Agreement. The Securitization Program has an initial termination date of June 15, 2018, with the option to renew for additional 364-day periods thereafter. As of September 30, 2015, $98.9 million of our accounts receivable are included in the Securitization Program. The amount of borrowings outstanding under the Receivables Financing Agreement totaled $56.9 million as of September 30, 2015, which is included in “Long-term debt” on the consolidated balance sheet.

NuStar Finance’s sole business consists of purchasing such receivables and providing them as collateral under the Securitization Program. NuStar Finance is a separate legal entity and the assets of NuStar Finance, including these accounts receivable, are not available to satisfy the claims of creditors of NuStar Energy, the Originators or their affiliates.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

ORGANIZATION AND BASIS OF PRESENTATION

ORGANIZATION AND BASIS OF PRESENTATION

Organization and Operations

NuStar Energy L.P. (NuStar Energy) (NYSE: NS) is a publicly held Delaware limited partnership engaged in the transportation of petroleum products and anhydrous ammonia, the terminalling and storage of petroleum products and the marketing of petroleum products. Unless otherwise indicated, the terms “NuStar Energy,” “the Partnership,” “we,” “our” and “us” are used in this report to refer to NuStar Energy L.P., to one or more of our consolidated subsidiaries or to all of them taken as a whole. NuStar GP Holdings, LLC (NuStar GP Holdings) (NYSE: NSH) owns our general partner, Riverwalk Logistics, L.P., and owns a 15.0% total interest in us as of September 30, 2015.

We conduct our operations through our subsidiaries, primarily NuStar Logistics, L.P. (NuStar Logistics) and NuStar Pipeline Operating Partnership L.P. (NuPOP). We have three business segments: pipeline, storage and fuels marketing.

Basis of Presentation

These unaudited condensed consolidated financial statements include the accounts of the Partnership and subsidiaries in which the Partnership has a controlling interest. Noncontrolling interests are separately disclosed on the financial statements. Inter-partnership balances and transactions have been eliminated in consolidation. We account for investments in joint ventures using the equity method of accounting.

These unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and with the instructions to the Quarterly Report on Form 10-Q and Article 10 of Regulation S-X of the Securities Exchange Act of 1934. Accordingly, they do not include all of the information and notes required by GAAP for complete consolidated financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included, and all disclosures are adequate. All such adjustments are of a normal recurring nature unless disclosed otherwise. Financial information for the three and nine months ended September 30, 2015 and 2014 included in these Condensed Notes to Consolidated Financial Statements is derived from our unaudited condensed consolidated financial statements. Operating results for the three and nine months ended September 30, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015. The consolidated balance sheet as of December 31, 2014 has been derived from the audited consolidated financial statements as of that date. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2014.

New Accounting Pronouncements

In September 2015, the Financial Accounting Standards Board (FASB) issued amended guidance for business combinations that eliminates the requirement to restate prior period financial statements for measurement period adjustments. The new guidance requires that the cumulative impact of a measurement period adjustment be recognized in the reporting period in which the adjustment is identified. The changes are effective for annual and interim periods beginning after December 15, 2015, and early adoption is permitted for financial statements that have not been issued. We will adopt these provisions January 1, 2016, and we do not expect the amended guidance to have a material impact on our financial position, results of operations or disclosures.

In July 2015, the FASB issued amended guidance that requires inventory to be measured at the lower of cost or net realizable value. The changes are effective for annual and interim periods beginning after December 15, 2016, and early adoption is permitted. We will adopt these provisions January 1, 2017, and we do not expect the amended guidance to have a material impact on our financial position, results of operations or disclosures.

In April 2015, the FASB issued amended guidance for the presentation of debt issuance costs. Under the amended guidance, debt issuance costs will be presented on the balance sheet as a deduction from the carrying value of the associated debt liability. In August 2015, the FASB issued amended guidance that would allow debt issuance costs related to line-of-credit agreements to continue to be presented as an asset on the balance sheet. The changes are effective for annual and interim periods beginning after December 15, 2015, and retrospective application is required. Early adoption is permitted. We will adopt these provisions January 1, 2016, and we do not expect the amended guidance to have a material impact on our financial position, results of operations or disclosures.

In February 2015, the FASB issued new consolidation guidance that modifies the criterion involved in a reporting organization’s evaluation of whether certain legal entities are subject to consolidation under the standard. The standard is effective for public companies for annual and interim reporting periods beginning after December 15, 2015, using one of two retrospective transition methods. Early adoption is permitted. We will adopt these provisions January 1, 2016, and we do not expect the guidance to have a material impact on our financial position, results of operations or disclosures.

In May 2014, the FASB and the International Accounting Standards Board jointly issued a comprehensive new revenue recognition standard. In August 2015, the FASB deferred the effective date by one year. The standard is now effective for public entities for annual and interim periods beginning after December 15, 2017, using one of two retrospective transition methods. Early adoption is permitted, but not before the original effective date. We are currently assessing the impact of this new guidance on our financial statements and disclosures, and we have not yet selected a transition method.

Business Combinations [Abstract]

ACQUISITIONS AND DISPOSITIONS

ACQUISITIONS AND DISPOSITIONS

Acquisitions

Linden Acquisition. On January 2, 2015, we acquired full ownership of ST Linden Terminal, LLC (Linden), which owns a refined products terminal in Linden, NJ with 4.3 million barrels of storage capacity (the Linden Acquisition). Linden is located on a 44-acre facility that provides deep-water terminalling capabilities in the New York Harbor and primarily stores petroleum products, including gasoline, jet fuel and fuel oils. Prior to the Linden Acquisition, Linden operated as a joint venture between us and Linden Holding Corp, with each party owning 50%.

In connection with the Linden Acquisition, we ceased applying the equity method of accounting and consolidated Linden, which is included in our storage segment. The condensed consolidated statements of comprehensive income include the results of operations for Linden commencing on January 2, 2015. On the acquisition date, we remeasured our existing 50% equity investment in Linden to its fair value of $128.0 million and we recognized a gain of $56.3 million in “Other income (expense), net” in the condensed consolidated statements of comprehensive income for the nine months ended September 30, 2015. We estimated the fair value using a market approach, which estimates the enterprise value based on an earnings multiple. We funded the acquisition with borrowings under our revolving credit agreement. The acquisition complements our existing storage operations, and having sole ownership of Linden strengthens our presence in the New York Harbor and the East Coast market.

We accounted for the Linden Acquisition using the acquisition method. The purchase price has been allocated based on the estimated fair values of the individual assets acquired and liabilities assumed at the date of the acquisition. The purchase price allocation was as follows (in thousands of dollars):

Cash paid for the Linden Acquisition	$	142,500
Fair value of liabilities assumed	22,865
Consideration	165,365
Acquisition date fair value of previously held equity interest	128,000
Total	$	293,365
Current assets	$	1,746
Property, plant and equipment	134,484
Goodwill	86,975
Intangible assets (a)	70,050
Other long-term assets	110
Purchase price allocation	$	293,365

(a) Intangible assets primarily consist of customer contracts and relationships and are being amortized over 10 years.

Dispositions

Discontinued Operations. In January 2015, we sold our terminal in Alamogordo, NM with storage capacity of 0.1 million barrels for proceeds of $1.1 million.We classified the associated property, plant and equipment as “Assets held for sale” on the consolidated balance sheet as of December 31, 2014. In 2014, we divested our terminals in Mobile, AL, Wilmington, NC and Dumfries, VA and our 75% interest in our facility in Mersin, Turkey (the Turkey Sale). We recognized a gain of $3.7 million on the Turkey Sale for the three and nine months ended September 30, 2014. We presented the results of operations for those facilities as discontinued operations. We allocated interest expense of $0.1 million and $0.8 million for the three and nine months ended September 30, 2014, respectively, to discontinued operations based on the ratio of net assets discontinued to consolidated net assets.

The following table summarizes the results from discontinued operations:

Income (loss) before income tax expense	$	—	$	2,831	$	774	$	(2,316	)

2014 Asphalt Sale. On February 26, 2014, we sold our remaining 50% ownership interest in NuStar Asphalt LLC to Lindsay Goldberg LLC (Lindsay Goldberg), a private investment firm (the 2014 Asphalt Sale). Effective February 27, 2014, NuStar Asphalt LLC changed its name to Axeon Specialty Products LLC (Axeon). Lindsay Goldberg now owns 100% of Axeon. As a result of the 2014 Asphalt Sale, we ceased applying the equity method of accounting.

Segment Reporting [Abstract]

SEGMENT INFORMATION

SEGMENT INFORMATION

Our reportable business segments consist of pipeline, storage and fuels marketing. Our segments represent strategic business units that offer different services and products. We evaluate the performance of each segment based on its respective operating income, before general and administrative expenses and certain non-segmental depreciation and amortization expense. General and administrative expenses are not allocated to the operating segments since those expenses relate primarily to the overall management at the entity level. Our principal operations include the transportation of petroleum products and anhydrous ammonia, the terminalling and storage of petroleum products and the marketing of petroleum products. Intersegment revenues result from storage agreements with wholly owned subsidiaries of NuStar Energy at lease rates consistent with rates charged to third parties for storage.

Results of operations for the reportable segments were as follows:

DERIVATIVES AND RISK MANAGEMENT ACTIVITIES

Derivative Instruments and Hedging Activities Disclosure [Abstract]

DERIVATIVES AND RISK MANAGEMENT ACTIVITIES

DERIVATIVES AND RISK MANAGEMENT ACTIVITIES

We utilize various derivative instruments to manage our exposure to interest rate risk and commodity price risk. Our risk management policies and procedures are designed to monitor interest rates, futures and swap positions and over-the-counter positions, as well as physical commodity volumes, grades, locations and delivery schedules, to help ensure that our hedging activities address our market risks. Our risk management committee oversees our trading controls and procedures and certain aspects of commodity and trading risk management. Our risk management committee also reviews all new commodity and trading risk management strategies in accordance with our risk management policy, as approved by our board of directors.

Interest Rate Risk

We are a party to certain interest rate swap agreements to manage our exposure to changes in interest rates. During the nine months ended September 30, 2015, we entered into forward-starting interest rate swap agreements with an aggregate notional amount of $450.0 million. Under the terms of the swaps, we pay a fixed rate and receive a rate based on three month USD LIBOR. We entered into these swaps in order to hedge the risk of changes in the interest payments attributable to changes in the benchmark interest rate during the period from the effective date of the swap to the issuance of the forecasted debt. These swaps qualified, and we designated them, as cash flow hedges of future interest payments associated with forecasted debt issuances in 2018 and 2020. We record the effective portion of mark-to-market adjustments as a component of “Accumulated other comprehensive income” (AOCI), and the amount in AOCI will be recognized in “Interest expense, net” as the forecasted interest payments occur or if the interest payments are probable not to occur. We had no forward-starting interest rate swap agreements as of December 31, 2014.

Commodity Price Risk

We are exposed to market risks related to the volatility of crude oil and refined product prices. In order to reduce the risk of commodity price fluctuations with respect to our crude oil and finished product inventories and related firm commitments to purchase and/or sell such inventories, we utilize commodity futures and swap contracts, which qualify and we designate as fair value hedges. Derivatives that are intended to hedge our commodity price risk, but fail to qualify as fair value or cash flow hedges, are considered economic hedges, and we record associated gains and losses in net income. The volume of commodity contracts is based on open derivative positions and represents the combined volume of our long and short open positions on an absolute basis, which totaled 6.1 millionbarrels and 4.7 million barrels as of September 30, 2015 and December 31, 2014, respectively. The fair values of our derivative instruments included in our consolidated balance sheets were as follows:

Certain of our derivative instruments are eligible for offset in the consolidated balance sheets and subject to master netting arrangements. Under our master netting arrangements, there is a legally enforceable right to offset amounts, and we intend to settle such amounts on a net basis.

FAIR VALUE MEASUREMENTS

Fair Value Disclosures [Abstract]

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS

We segregate the inputs used in measuring fair value into three levels: Level 1, defined as observable inputs such as quoted prices for identical assets or liabilities in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable, such as quoted prices for similar assets or liabilities in active markets or quoted prices for identical assets or liabilities in markets that are not active; and Level 3, defined as unobservable inputs in which little or no market data exists. We consider counterparty credit risk and our own credit risk in the determination of all estimated fair values.

Recurring Fair Value Measurements

The following assets and liabilities are measured at fair value on a recurring basis:

Product Imbalances.We value our assets and liabilities related to product imbalances using quoted market prices in active markets as of the reporting date. Therefore, we include these product imbalances in Level 1 of the fair value hierarchy.

Interest Rate Swaps.We estimate the fair value of our forward-starting interest rate swaps using discounted cash flows, which use observable inputs such as time to maturity and market interest rates. Therefore, we include these interest rate swaps in Level 2 of the fair value hierarchy.

Commodity Derivatives.We base the fair value of certain of our commodity derivative instruments on quoted prices on an exchange; accordingly, we include these items in Level 1 of the fair value hierarchy. We also have derivative instruments for which we determine fair value using industry pricing services and other observable inputs, such as quoted prices on an exchange for similar derivative instruments. Therefore, we include these derivative instruments in Level 2 of the fair value hierarchy. See Note 7 for a discussion of our derivative instruments.

Guarantees. We provide credit support, such as guarantees, letters of credit and cash collateral, as applicable, of up to $150.0 million to Axeon. As of September 30, 2015 and December 31, 2014, we provided guarantees mainly for commodity purchases, lease obligations and certain utilities for Axeon with an aggregate maximum potential exposure of $55.9 million and $25.3 million, respectively, and two guarantees that do not specify a maximum amount. A majority of these guarantees have no expiration date. We estimated the fair value of guarantees we have issued on behalf of Axeon considering the probability of default by Axeon and an estimate of the amount we would be obligated to pay under the guarantees at the time of default based on the guarantees outstanding as of September 30, 2015 and December 31, 2014. Our estimate of the fair value is based on significant inputs not observable in the market and thus falls within Level 3 of the fair value hierarchy.

The following table summarizes the activity in our Level 3 liabilities:

	Nine Months Ended September 30, 2015
	(Thousands of Dollars)
Beginning balance	$	580
Adjustments to guarantee liability	706
Ending balance	$	1,286

Fair Value of Financial Instruments

We recognize cash equivalents, receivables, note receivables, payables and debt in our consolidated balance sheets at their carrying amounts. The fair values of these financial instruments, except for the $190.0 million term loan to Axeon (the Axeon Term Loan) and long-term debt, approximate their carrying amounts. The estimated fair value and carrying amounts of the long-term debt and the Axeon Term Loan were as follows:

	September 30, 2015				December 31, 2014
	Fair Value		Carrying Amount		Fair Value		Carrying Amount
	(Thousands of Dollars)
Long-term debt	$	3,073,330	$	3,109,359	$	2,764,242	$	2,749,452
Axeon Term Loan	$	169,607	$	169,941	$	164,386	$	169,235

We estimated the fair value of our publicly-traded senior notes based upon quoted prices in active markets; therefore, we determined that the fair value of our publicly-traded senior notes falls in Level 1 of the fair value hierarchy. For our other debt, for which a quoted market price is not available, we estimated the fair value using a discounted cash flow analysis using current incremental borrowing rates for similar types of borrowing arrangements and determined that the fair value falls in Level 2 of the fair value hierarchy.

We estimated the fair value of the Axeon Term Loan using discounted cash flows, which use observable inputs such as time to maturity and market interest rates, and determined the fair value falls in Level 2 of the fair value hierarchy.

As of September 30, 2015, the carrying amount of the receivable for the Axeon Term Loan is $169.9 million, consisting of the following: (i) the outstanding principal amount from the Axeon Term Loan of $190.0 million; (ii) plus the fair value of guarantees of $1.3 million as of September 30, 2015; and (iii) less equity losses from our investment in Axeon of $21.3 million incurred prior to the 2014 Asphalt Sale and after the carrying value of our equity investment in Axeon was reduced to zero. The carrying value of the Axeon Term Loan is included in “Other long-term assets, net” on the consolidated balance sheets. We review the financial information of Axeon monthly for possible credit loss indicators. Axeon failed to make a scheduled principal payment by September 30, 2015, which will increase the interest rate until Axeon makes the payment.

NET INCOME PER UNIT

NET INCOME PER UNIT

We have identified the general partner interest and incentive distribution rights as participating securities and use the two-class method when calculating the net income per unit applicable to limited partners, which is based on the weighted-average number of common units outstanding during the period. Basic and diluted net income per unit applicable to limited partners are the same because we have no potentially dilutive securities outstanding.

The following table details the calculation of earnings per unit:

Allocations of Net Income

Our partnership agreement, as amended, sets forth the calculation to be used to determine the amount and priority of cash distributions that the common unitholders and the general partner will receive. The partnership agreement also contains provisions for the allocation of net income and loss to the unitholders and the general partner. For purposes of maintaining partner capital accounts, the partnership agreement specifies that items of income and loss shall be allocated among the partners in accordance with their respective percentage interests. Normal allocations according to percentage interests are made after giving effect to priority income allocations, if any, in an amount equal to incentive cash distributions allocated 100% to the general partner.

The following table details the calculation of net income applicable to the general partner:

Commitments and Contingencies Disclosure [Abstract]

COMMITMENTS AND CONTINGENCIES

COMMITMENTS AND CONTINGENCIES

Contingencies

We have contingent liabilities resulting from various litigation, claims and commitments. We record accruals for loss contingencies when losses are considered probable and can be reasonably estimated. Legal fees associated with defending the Partnership in legal matters are expensed as incurred. As of September 30, 2015, we have accrued $4.2 million for contingent losses. The amount that will ultimately be paid may differ from the recorded accruals, and the timing of such payments is uncertain. In addition, due to the inherent uncertainty of litigation, there can be no assurance that the resolution of any particular claim or proceeding would not have a material adverse effect on our results of operations, financial position or liquidity.
