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 14.9% total interest in us as of March 31, 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 months ended March 31, 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 months ended March 31, 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 April 2015, the Financial Accounting Standards Board (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. 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 are currently assessing the impact of this new guidance on our financial statements and disclosures, and we have not yet selected a transition method.

In May 2014, the FASB and the International Accounting Standards Board jointly issued a comprehensive new revenue recognition standard. The standard is effective for public entities for annual and interim periods beginning after December 15, 2016, using one of two retrospective transition methods. Early adoption is not permitted for public entities. 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 percent.

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, net” in the condensed consolidated statements of comprehensive income for the three months ended March 31, 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 preliminarily allocated based on the estimated fair values of the individual assets acquired and liabilities assumed at the date of the acquisition pending completion of an independent evaluation. The preliminary 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	129,400
Goodwill	87,059
Intangible assets	75,050
Other long-term assets	110
Purchase price allocation	$	293,365

The 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. We presented the results of operations for those facilities as discontinued operations. We allocated interest expense of $0.4 million for the three months ended March 31, 2014 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 March 31,
	2015		2014
	(Thousands of Dollars)
Revenues	$	208	$	1,821
Income (loss) before income tax expense	$	774	$	(3,359	)

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:



	March 31, 2015		December 31, 2014
	(Thousands of Dollars)
Crude oil	$	539	$	3,527
Finished products	34,246		43,206
Materials and supplies	8,908		8,980
Total	$	43,693	$	55,713

4. DEBT

Revolving Credit Agreement

During the three months ended March 31, 2015, the balance under our $1.5 billion five-year revolving credit agreement (the Revolving Credit Agreement) increased by $239.1 million, which we used for general partnership purposes and to fund the Linden Acquisition. The Revolving Credit Agreement 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 March 31, 2015, our weighted-average interest rate was 1.9% and we had $840.6 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. However, 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. As of March 31, 2015, our consolidated debt coverage ratio could not exceed 5.50-to-1.00, as a result of the Linden Acquisition in January 2015. 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 March 31, 2015, our consolidated debt coverage ratio was 4.1x, and we had $602.5 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 interest rate was 0.1% as of March 31, 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 three months ended March 31, 2015, we received $0.5 million from the trustee. As of March 31, 2015, the amount remaining in trust totaled $71.0 million.

Short-term Lines of Credit

As of March 31, 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 $46.0 million outstanding under these short-term lines of credit as of March 31, 2015.

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 March 31, 2015, we have accrued $4.4 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.

Recurring Fair Value Measurements

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



	March 31, 2015

Total	$	(1,388	)	$	(4,623	)	$	(580	)	$	(6,591	)

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 March 31, 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 $25.9 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 March 31, 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:

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:



	March 31, 2015				December 31, 2014
	Fair Value		Carrying Amount		Fair Value		Carrying Amount
	(Thousands of Dollars)
Long-term debt	$	3,026,670	$	2,987,413	$	2,764,242	$	2,749,452
Axeon Term Loan	$	165,562	$	169,250	$	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 March 31, 2015, the carrying amount of the receivable for the Axeon Term Loan is $169.3 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 $0.6 million as of March 31, 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 non-payment indicators.

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 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 change in interest rates. During the three months ended March 31, 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.

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.

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 14.9% total interest in us as of March 31, 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

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, net” in the condensed consolidated statements of comprehensive income for the three months ended March 31, 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. We presented the results of operations for those facilities as discontinued operations.

Table of Contents

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 5,463 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 6.3 million barrels. In addition, we own a 2,000 mile anhydrous ammonia pipeline (the Ammonia Pipeline) and 1,245 miles of Central West System crude oil pipelines including approximately 3.9 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 $21.5 million and throughputs increased 180,264 barrels per day for the three months ended March 31, 2015, compared to the three months ended March 31, 2014, primarily due to:


•	an increase in revenues of $13.4 million and an increase in throughputs of 110,005 barrels per day on crude oil pipelines that serve Eagle Ford Shale production, primarily resulting from continued growth in the region and the completion of expansion projects in 2014 that increased our overall capacity; and


•	an increase in revenues of $6.8 million and an increase in throughputs of 63,167 barrels per day as a result of a turnaround during the first quarter of 2014 at the refinery served by our McKee system.

Operating expenses increased $3.7 million for the three months ended March 31, 2015, compared to the three months ended March 31, 2014, primarily due to an increase in power costs of $1.5 million mainly due to the increase in throughputs on pipelines that serve Eagle Ford Shale production in South Texas and an increase in rental cost of $1.3 million associated with our Eagle Ford crude oil pipelines.

Depreciation and amortization expense increased $2.1 million for the three months ended March 31, 2015, compared to the three months ended March 31, 2014, mainly due to the completion of various projects that serve Eagle Ford Shale production.

Storage

Throughput revenues increased $4.2 million and throughputs increased 58,933 barrels per day for the three months ended March 31, 2015, compared to the three months ended March 31, 2014, primarily due to:


•	an increase in revenues of $2.7 million and an increase in throughputs of 66,516 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 in 2014; and


•	an increase in revenues of $1.7 million and an increase in throughputs of 37,789 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.

The increases in storage throughput revenues and throughputs were partially offset by a decrease in revenues of $0.5 million and a decrease in throughputs of 41,988 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 facilities.

Storage lease revenues increased $13.5 million for the three months ended March 31, 2015, compared to the three months ended March 31, 2014, primarily due to:


•	an increase of $10.0 million as a result of the Linden Acquisition; and


•	an increase of $8.6 million at our St. Eustatius terminal facility, mainly due to higher ancillary activity and a full quarter of storage revenue in 2015 compared to a partial quarter in 2014 as previously idled tanks were leased beginning in March 2014.

The increases in storage lease revenues were partially offset by a decrease of $3.4 million at our St. James terminal, mainly due to reduced unit train activity and a decrease of $3.1 million at our UK and Amsterdam terminal facilities, primarily due to the effect of foreign exchange rates.

Operating expenses increased $7.4 million for the three months ended March 31, 2015, compared to the three months ended March 31, 2014, primarily due to:


•	an increase of $2.9 million as a result of the Linden Acquisition;


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


•	an increase of $2.1 million in regulatory and maintenance expenses, mainly at our St. James and St. Eustatius terminal facilities.

Depreciation and amortization expense increased $4.4 million for the three months ended March 31, 2015, compared to the three months ended March 31, 2014, mainly due to the assets associated with the Linden Acquisition.

Fuels Marketing

Segment operating income increased slightly for the three months ended March 31, 2015, compared to the three months ended March 31, 2014. Operating income increased $7.5 million from our bunker fuel operations mainly due to stronger product margins at our St. Eustatius and Texas City facilities, while lower product margins led to a decrease of $6.7 million in operating income from fuel oil trading.

Table of Contents

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 $4.2 million for the three months ended March 31, 2015, compared to the three months ended March 31, 2014, mainly due to 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 as well as an increase in salaries and wages.

Equity in loss of joint ventures primarily relates to our equity investment in Axeon prior to the 2014 Asphalt Sale.

Interest expense, net decreased $2.4 million for the three months ended March 31, 2015, compared to the three months ended March 31, 2014, mainly due to increased interest income from the $190.0 million term loan to Axeon (the Axeon Term Loan) and higher capitalized interest resulting from increased capital projects.

Other income, net increased $58.6 million for the three months ended March 31, 2015, compared to the three months ended March 31, 2014, mainly due to the $56.3 million gain associated with the Linden Acquisition.

For the three months ended March 31, 2015, we recorded income from discontinued operations of $0.8 million, compared to a loss from discontinued operations of $3.4 million for the three months ended March 31, 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

Pipeline Segment

We expect our pipeline segment earnings for the second quarter of 2015 to be lower than the first quarter of 2015 due to a turnaround at one of our customer’s refineries as well as a seasonal increase in maintenance expenses. However, we expect both the second quarter of 2015 and the full-year 2015 earnings to exceed the comparable periods in 2014. We expect earnings in 2015 to benefit from the planned completion of pipeline expansion projects, reduced turnaround activity at our customers’ refineries and the July 1, 2015 tariff increase on our pipelines subject to regulation by the Federal Energy Regulatory Commission. Although the drop in crude prices in late 2014 and early 2015 has not reduced the demand for our transportation services so far, continued weak crude oil prices could have a negative impact on demand and our earnings in the future.

Storage Segment

We expect storage segment earnings for the second quarter of 2015 to be comparable to the first quarter of 2015 and slightly higher than the second quarter of 2014. We expect the earnings for the full-year of 2015 to exceed 2014 results. These improved 2015 results are mainly due to our January 2015 purchase of the remaining 50% interest in the former joint venture terminal in Linden, New Jersey and higher throughputs at our North Beach terminal as a result of the increase in Eagle Ford Shale crude oil being shipped to Corpus Christi.

Fuels Marketing Segment

We expect second quarter of 2015 results for our fuels marketing segment to be lower than the first quarter of 2015 due to seasonal declines in our bunker sales. We expect the full-year 2015 results in this segment to be comparable to 2014 results. 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.

We expect that our reliability capital spending will increase significantly for the remainder of the year due to required tank inspections and various other regulatory projects.

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 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 annual total operating expenses, interest expense, 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 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. Additionally, 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. We also expect to fund our reliability capital expenditures with cash from operations as well as from other sources of liquidity as described below.

Cash Flows for the Three Months Ended March 31, 2015 and 2014

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



	Three Months Ended March 31,
	2015			2014
	(Thousands of Dollars)
Net cash provided by (used in):
Operating activities	$	122,582		$	63,325
Investing activities	(229,836		)	(76,331		)
Financing activities	104,011			(42,702		)
Effect of foreign exchange rate changes on cash	(6,486		)	(2,437		)
Net decrease in cash and cash equivalents	$	(9,729	)	$	(58,145	)

Net cash provided by operating activities for the three months ended March 31, 2015 was $122.6 million, compared to $63.3 million for the three months ended March 31, 2014 primarily due to higher net income in 2015. In addition, we increased our working capital $7.8 million for the three months ended March 31, 2015, compared to $38.8 million for the three months ended March 31, 2014.

For the three months ended March 31, 2015, net cash provided by operating activities was used to fund our distributions to unitholders and our general partner and reliability capital expenditures. Proceeds from debt borrowings, net of repayments, combined with cash on hand, were used to fund the Linden Acquisition and strategic capital expenditures.

For the three months ended March 31, 2014, net cash provided by operating activities and cash on hand were used to fund our distributions to unitholders and our general partner and reliability capital expenditures. Proceeds from long-term debt borrowings, net of repayments, combined with cash on hand, were used to fund strategic capital expenditures and advances to Axeon before the 2014 Asphalt Sale.

Revolving Credit Agreement

As of March 31, 2015, our consolidated debt coverage ratio could not exceed 5.50-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 March 31, 2015, our consolidated debt coverage ratio was 4.1x, and we had $602.5 million available for borrowing. 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.

Short-term Lines of Credit

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 three months ended March 31, 2015, our reliability capital expenditures totaled $6.8 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 three months ended March 31, 2015 totaled $210.8 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.

During the three months ended March 31, 2014, our reliability capital expenditures totaled $4.8 million, primarily related to maintenance upgrade projects at our terminals. Strategic capital expenditures for the three months ended March 31, 2014 totaled $49.7 million and were primarily related to projects associated with Eagle Ford Shale production in South Texas.

For the full year 2015, we expect to incur approximately $445.0 million to $475.0 million of capital expenditures, including approximately $45.0 million to $55.0 million for reliability capital expenditures and $400.0 million to $420.0 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 for the products we market. This seasonality in demand affects 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 March 31, 2015, we provided guarantees for Axeon with an aggregate maximum potential exposure of $25.9 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 March 31, 2015, we have also provided $48.1 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 more detailed discussion of the Axeon Term Loan and credit support.

(a)	The distribution was announced on April 22, 2015.

Debt Obligations

As of March 31, 2015, we were a party to the following debt agreements:


•	revolving credit agreement due October 29, 2019, with a balance of $840.6 million as of March 31, 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; and


•	$80.0 million line of credit agreements with $46.0 million outstanding as of March 31, 2015.

Management believes that, as of March 31, 2015, we are in compliance with all ratios and covenants of our revolving credit agreement. Our other debt obligations do not contain any financial covenants that are different than those contained in our revolving credit agreement. However, 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 three months ended March 31, 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

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 revolving credit agreement and the Gulf Opportunity Zone Revenue Bonds expose us to increases in interest rates. During the three months ended March 31, 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.
