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 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, 2014.
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 our 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, 2014 and 2013 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, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014. The consolidated balance sheet as of December 31, 2013 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, 2013.
New Accounting Pronouncements
In April 2014, the Financial Accounting Standards Board (FASB) amended the disclosure requirements for discontinued operations. Under the amended guidance, a discontinued operation is defined as the disposal of a component that represents a strategic shift that has (or will have) a major effect on an entity's operations and financial results. The amended guidance also requires expanded disclosures about discontinued operations and disposals of a significant part of an entity that do not qualify as discontinued operations. The amended guidance is effective prospectively to new disposals and new classifications of assets held for sale in annual periods beginning after December 15, 2014, and interim periods within those annual periods. Accordingly, we plan to adopt the amended guidance January 1, 2015.
2. DISPOSITIONS AND DISCONTINUED OPERATIONS
Dispositions
On February 26, 2014, we sold our remaining 50% ownership interest in NuStar Asphalt LLC (Asphalt JV) to Lindsay Goldberg LLC (Lindsay Goldberg), a private investment firm (the Asphalt JV Sale). Lindsay Goldberg now owns 100% of Asphalt JV. Unless otherwise indicated, the term “Asphalt JV” is used in this report to refer to NuStar Asphalt LLC, to one or more of its consolidated subsidiaries or to all of them taken as a whole. Effective February 27, 2014, NuStar Asphalt LLC changed its name to Axeon Specialty Products LLC. As a result of the Asphalt JV Sale, we ceased applying the equity method of accounting. Upon completion of the Asphalt JV Sale, the $250.0 million unsecured revolving credit facility provided by us to Asphalt JV (the NuStar JV Facility) was converted from a revolving credit agreement into a $190.0 million term loan (the NuStar Term Loan). See Note 8 for a discussion of our agreements with Asphalt JV. Also at the time of the sale, the parties agreed to: (i) terminate the terminal services agreements with respect to our terminals in Rosario, NM, Catoosa, OK and Houston, TX; (ii) amend the terminal services agreements for our terminals in Baltimore, MD and Jacksonville, FL; and (iii) transfer ownership of both the Wilmington, NC and Dumfries, VA terminals to Asphalt JV, which were categorized as assets held for sale at December 31, 2013.

Discontinued Operations
Terminals Held for Sale. In addition to the terminals located in Wilmington, NC and Dumfries, VA, we have identified and plan to divest of several non-strategic, underperforming terminal facilities. As a result, we have reclassified the associated property, plant and equipment as “Assets held for sale” on the consolidated balance sheet. We presented the results of operations for those facilities, which were previously reported in the storage segment, as discontinued operations for all periods presented. We allocated interest expense of $0.4 million for each of the three months ended March 31, 2014 and 2013 to discontinued operations based on the ratio of net assets discontinued to consolidated net assets.
San Antonio Refinery. On January 1, 2013, we sold our fuels refinery in San Antonio, Texas (the San Antonio Refinery) and related assets for approximately $117.0 million (the San Antonio Refinery Sale). We have presented the results of operations for the San Antonio Refinery and related assets as discontinued operations for all periods presented. We recognized a gain of $9.3 million on the sale, which is included in discontinued operations for the three months ended March 31, 2013.
The following table summarizes the results from discontinued operations:

| Three Months Ended March 31,
| 2014 |  | 2013
| (Thousands of Dollars)
Revenues | $ | 1,821 |  |  | $ | 1,709 |
(Loss) income before income tax expense | $ | (3,359 | ) |  | $ | 4,250 |

3. INVENTORIES
Inventories consisted of the following:

| March 31, 2014 |  | December 31, 2013
| (Thousands of Dollars)
Crude oil | $ | 6,183 |  |  | $ | 6,485 |
Finished products | 88,541 |  |  | 123,656 |
Materials and supplies | 7,923 |  |  | 8,006 |
Total | $ | 102,647 |  |  | $ | 138,147 |

4. DEBT
Revolving Credit Agreement
During the three months ended March 31, 2014, the balance under our $1.5 billion five-year revolving credit agreement (the 2012 Revolving Credit Agreement) increased by $55.7 million, which we used for general partnership purposes. The 2012 Revolving Credit Agreement bears interest, at our option, based on either an alternative base rate or a LIBOR-based rate. The interest rate on the 2012 Revolving Credit Agreement is subject to adjustment if our debt rating is downgraded (or subsequently upgraded) by certain credit rating agencies. As of March 31, 2014, our weighted average interest rate was 2.2%.
The 2012 Revolving Credit Agreement contains customary restrictive covenants, including requiring us to maintain, as of the end of each rolling period, which consists of any period of four consecutive fiscal quarters, a consolidated debt coverage ratio (consolidated indebtedness to consolidated EBITDA, as defined in the 2012 Revolving Credit Agreement) not to 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 the 2012 Revolving Credit Agreement to an amount less than the total amount available for borrowing. As of March 31, 2014, our consolidated debt coverage ratio was 4.4x, and we had $784.0 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 we pay interest monthly. The interest rate was 0.1% as of March 31, 2014. Following the issuance, the proceeds were deposited with a trustee and are disbursed to us upon our
7

Table of Contents
NUSTAR ENERGY L.P. AND SUBSIDIARIES
CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)
request for reimbursement of expenditures related to our St. James terminal expansions. 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, 2014, we received $0.5 million from the trustee. As of March 31, 2014, the amount remaining in trust totaled $83.0 million.
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, 2014, we have accrued $0.8 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:

Product Imbalances. We value our assets and liabilities related to product imbalances using quoted market prices in active markets as of the reporting date.
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.
Contingent Consideration. On December 13, 2012, NuStar Logistics acquired certain assets, including 100% of the partnership interest in TexStar Crude Oil Pipeline, LP, from TexStar Midstream Services, LP and certain of its affiliates (collectively, TexStar) for approximately $325.0 million (the TexStar Asset Acquisition), including contingent consideration. In connection with the TexStar Asset Acquisition, we could be obligated to pay additional consideration to TexStar. Such obligations are dependent upon the cost of work required to complete certain assets and obtain outstanding real estate rights (collectively, the Contingent Consideration). We estimated the fair value of the Contingent Consideration based on significant inputs not observable in the market and have therefore reported that amount within Level 3 of the fair value hierarchy. Based on our assessment of the costs necessary to complete the assets in accordance with our agreement with TexStar, and considering the probability of possible outcomes, we determined that it is unlikely we would be obligated to pay a portion of the Contingent Consideration. The undiscounted amount of potential future payments that we could be required to make under the applicable agreements is between $0 and $1.3 million.
Guarantees. As of March 31, 2014, we recorded a liability of $2.6 million representing the fair value of guarantees we have issued on behalf of Asphalt JV. We estimated the fair value considering the probability of default by Asphalt JV and an estimate of the amount we would be obligated to pay under the guarantees at the time of default. We calculated the fair value based on the guarantees outstanding as of March 31, 2014, totaling $111.0 million, plus two guarantees that do not specify a maximum amount, but for which we believe any amounts due would be minimal. 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. See Note 8 for a discussion of our agreements with Asphalt JV.
In the event we are obligated to perform under any of these guarantees, the amount paid by us will be treated as additional borrowings under the NuStar JV Term Loan. As a result, we increased the carrying value of the note receivable from Asphalt JV by the same amount as the liability for the fair value of the guarantees outstanding as of March 31, 2014.

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

| (Thousands of Dollars)
Beginning balance | $ | 3,198 |
Adjustment to guarantee liability | 740 |
Ending balance | $ | 3,938 |

Non-recurring Fair Value Measurements
We reclassified the property, plant and equipment associated with certain terminals as “Assets held for sale” on the consolidated balance sheet and recorded those assets at fair value, less costs to sell. We estimated the fair values of $19.9 million and $22.0 million as of March 31, 2014 and December 31, 2013, respectively, using a weighted-average of values calculated using an income approach and a market approach. The income approach calculates fair value by discounting the estimated net cash flows generated by the related terminal. The market approach involves estimating the fair value measurement on an earnings multiple based on public company transaction data. 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.
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 a note receivable from Asphalt JV and debt, approximate their carrying amounts. The estimated fair value and carrying amounts of the debt and note receivable were as follows:

| March 31, 2014 |  | December 31, 2013
| Fair Value |  | Carrying Amount |  | Fair Value |  | Carrying Amount
| (Thousands of Dollars)
Debt | $ | 2,764,360 |  |  | $ | 2,710,117 |  |  | $ | 2,636,734 |  |  | $ | 2,655,553 |
Note receivable from Asphalt JV | $ | 144,949 |  |  | $ | 171,275 |  |  | $ | 133,416 |  |  | $ | 165,440 |

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.
The note receivable related to the NuStar JV Term Loan is recorded at: (i) the outstanding principal amount of $190.0 million; (ii) plus the fair value of guarantees of $2.6 million; and (iii) reduced by equity losses from our investment in Asphalt JV of $21.3 million incurred after the carrying value of our investment in Asphalt JV was reduced to zero. We review the financial information of Asphalt JV monthly for possible non-payment indicators.
We estimated the fair value of the note receivable 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. See Note 8 for additional information on the note receivable from Asphalt JV.
7. DERIVATIVES AND RISK MANAGEMENT ACTIVITIES
We utilize various derivative instruments to manage our exposure to commodity price risk and interest rate 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 were a party to certain interest rate swap agreements to manage our exposure to changes in interest rates, which included forward-starting interest rate swap agreements related to the interest payments associated with forecasted probable debt

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)
issuances. These swaps qualified, and we designated them, as cash flow hedges. In 2013, we terminated our remaining forward-starting interest rate swap agreements. We recorded the effective portion of mark-to-market adjustments as a component of “Accumulated other comprehensive loss” (AOCI). The amount accumulated in AOCI is amortized into “Interest expense, net” over the term of the forecasted debt as the interest payments occur or if the interest payments are probable not to occur. As of March 31, 2014, we had no forward-starting interest rate swap agreements.
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 14.1 million barrels and 15.2 million barrels as of March 31, 2014 and December 31, 2013, respectively.
As of March 31, 2014 and December 31, 2013, we had $1.9 million and $3.3 million, respectively, of margin deposits related to our derivative instruments.
The fair values of our derivative instruments included in our consolidated balance sheets were as follows:

NuStar GP, LLC
Our operations are managed by NuStar GP, LLC, the general partner of our general partner. Under a services agreement between NuStar Energy and NuStar GP, LLC, employees of NuStar GP, LLC perform services for our U.S. operations. Certain of our wholly owned subsidiaries employ persons who perform services for our international operations. Employees of NuStar GP, LLC provide services to both NuStar Energy and NuStar GP Holdings; therefore, we reimburse NuStar GP, LLC for all employee costs, other than the expenses allocated to NuStar GP Holdings.
We had a payable to NuStar GP, LLC of $13.6 million and $8.3 million as of March 31, 2014 and December 31, 2013, respectively, with both amounts representing payroll, employee benefit plan expenses and unit-based compensation. We also had a long-term payable to NuStar GP, LLC as of March 31, 2014 and December 31, 2013 of $39.4 million and $41.1 million, respectively, related to amounts payable for retiree medical benefits and other post-employment benefits.
Asphalt JV
As a result of the Asphalt JV Sale, we ceased reporting transactions between us and Asphalt JV as related party transactions in our consolidated financial statements on February 26, 2014.
Financing Agreements and Credit Support. Effective upon the Asphalt JV Sale, the NuStar JV Facility was converted into the NuStar Term Loan. The NuStar Term Loan will step down from $190.0 million over time: first, to $175.0 million on December 31, 2014 and then to $150.0 million on September 30, 2015. While the NuStar Term Loan does not provide for any other scheduled payments, Asphalt JV is required to use all of its excess cash, as defined in the NuStar Term Loan, to repay the NuStar Term Loan. Like the NuStar JV Facility, the NuStar Term Loan must be repaid in full on September 28, 2019. All repayments of the NuStar Term Loan, including those scheduled in 2014 and 2015, are subject to Asphalt JV meeting certain restrictive requirements contained in its third-party credit facility. The carrying value of the NuStar Term Loan is included in “Other long-term assets, net” on the consolidated balance sheet as of March 31, 2014.
NuStar Energy will continue to provide credit support, such as guarantees, letters of credit and cash collateral, as applicable, of up to $150.0 million. Our obligation to provide credit support will be reduced by a minimum of $25.0 million beginning February 2016 and will terminate in full no later than September 28, 2019. As of March 31, 2014, we provided guarantees for commodity purchases, lease obligations and certain utilities for Asphalt JV with an aggregate maximum potential exposure of $111.0 million, plus two guarantees to suppliers that do not specify a maximum amount, but for which we believe any amounts due would be minimal. A majority of these guarantees have no expiration date. As of March 31, 2014, we have also provided $11.6 million in letters of credit on behalf of Asphalt JV. In the event we are obligated to perform under any of these guarantees or letters of credit, the amount paid by us will be treated as additional borrowings under the NuStar Term Loan.
Crude Oil Supply Agreement. We were a party to a crude oil supply agreement with Asphalt JV (the Asphalt JV Crude Oil Supply Agreement) that committed Asphalt JV to purchase from us a minimum number of barrels of crude oil in a given year. The Asphalt JV Crude Oil Supply Agreement terminated effective January 1, 2014. As of December 31, 2013, we had a receivable from Asphalt JV of $50.7 million, mainly associated with crude oil sales under the Asphalt JV Crude Oil Supply Agreement.
Services Agreement Between Asphalt JV and NuStar GP, LLC. In conjunction with the Asphalt Sale, NuStar GP, LLC entered into a services agreement with Asphalt JV, effective September 28, 2012 (the Asphalt JV Services Agreement). The Asphalt JV

Services Agreement provides that NuStar GP, LLC will furnish certain administrative and other operating services necessary to conduct the business of Asphalt JV. Asphalt JV will compensate NuStar GP, LLC for these services through an annual fee totaling $10.0 million, subject to adjustment based on the annual merit increase percentage applicable to NuStar GP, LLC employees for the most recently completed contract year. Effective upon the Asphalt JV Sale, the Asphalt JV Services Agreement was amended and will terminate on June 30, 2014, with the option to extend the term for an additional three months for certain services with 30 days prior written notice. Asphalt JV provided written notice to reduce the level of services that NuStar GP, LLC provides to Asphalt JV, which is currently at 63% of the original service level.

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:

10. NET INCOME PER UNIT
We have identified the general partner interest and incentive distribution rights (IDR) 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.

12. SEGMENT INFORMATION
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 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. Related party revenues mainly result from storage agreements with our joint ventures.
Results of operations for the reportable segments were as follows:

OVERVIEW
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, 2014. Our Management’s Discussion and Analysis of Financial Condition and Results of Operations is presented in six sections:

• | Overview

• | Results of Operations

• | Trends and Outlook

• | Liquidity and Capital Resources

• | Related Party Transactions

• | Critical Accounting Policies

Dispositions
Asphalt JV Sale. On February 26, 2014, we sold our remaining 50% ownership interest in NuStar Asphalt LLC (Asphalt JV) to Lindsay Goldberg LLC (Lindsay Goldberg), a private investment firm (the Asphalt JV Sale). Lindsay Goldberg now owns 100% of Asphalt JV. Effective February 27, 2014, NuStar Asphalt LLC changed its name to Axeon Specialty Products LLC. As a result of the Asphalt JV Sale, we ceased applying the equity method of accounting. Upon completion of the Asphalt JV Sale, the $250.0 million unsecured revolving credit facility provided by us to Asphalt JV (the NuStar JV Facility) was converted into a $190.0 million term loan (the NuStar Term Loan). Also at the time of the sale, the parties agreed to: (i) terminate the terminal services agreements with respect to our terminals in Rosario, NM, Catoosa, OK and Houston, TX; (ii) amend the terminal services agreements for our terminals in Baltimore, MD and Jacksonville, FL; and (iii) transfer ownership of both the Wilmington, NC and Dumfries, VA terminals to Asphalt JV, which were categorized as assets held for sale at December 31, 2013.
Terminal Facilities Held for Sale. In addition to the terminals located in Wilmington, NC and Dumfries, VA, we have identified and plan to divest of several non-strategic, underperforming terminal facilities, and as of March 31, 2014 and December 31, 2013, we have reclassified the property, plant and equipment associated with these assets as “Assets held for sale” on the consolidated balance sheet. We presented the results of operations for these assets, previously in the storage segment, as discontinued operations for all periods presented.
San Antonio Refinery Sale. On January 1, 2013, we sold our fuels refinery in San Antonio, Texas (the San Antonio Refinery) and related assets for approximately $117.0 million (the San Antonio Refinery Sale). We have presented the results of
25

Table of Contents
operations for the San Antonio Refinery and related assets as discontinued operations for all periods presented. We recognized a gain of $9.3 million on the sale, which is included in discontinued operations for the three months ended March 31, 2013.
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 are divided into three reportable business segments: pipeline, storage and fuels marketing.
Pipeline. We own common carrier refined product pipelines covering approximately 5,463 miles, consisting of the Central West System, the East Pipeline and the North Pipeline. In addition, we own a 2,000 mile anhydrous ammonia pipeline (the Ammonia Pipeline), 1,180 miles of crude oil pipelines and approximately 10.0 million barrels of storage located along our pipelines. 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, the United Kingdom and Turkey providing approximately 84.0 million barrels of storage capacity. Our terminals and storage facilities provide storage and handling services on a fee basis for petroleum products, specialty chemicals and other liquids, including crude oil and other feedstocks.
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.

Highlights
Net income increased $15.2 million for the three months ended March 31, 2014, compared to the three months ended March 31, 2013, mainly due to an increase in segment operating income and decreases in the equity in loss of joint ventures and general and administrative expenses. Segment operating income increased $11.2 million for the three months ended March 31, 2014, compared to the three months ended March 31, 2013, primarily due to increased segment operating income from the pipeline and fuels marketing segments, partially offset by decreased operating income from the storage segment.
In addition, we recorded a loss from discontinued operations for the three months ended March 31, 2014, compared to income from discontinued operations for the three months ended March 31, 2013. Discontinued operations include the results of operations of the San Antonio Refinery and related assets, which we sold on January 1, 2013, and certain storage assets that were classified as “Assets held for sale” on the consolidated balance sheet as of December 31, 2013.

Table of Contents
Pipeline
Revenues increased $9.7 million and throughputs increased 9,902 barrels per day for the three months ended March 31, 2014, compared to the three months ended March 31, 2013, primarily due to:

• | an increase in revenues of $7.1 million and an increase in throughputs of 22,559 barrels per day on crude oil pipelines that serve Eagle Ford Shale production in South Texas, primarily resulting from continued growth in the region, the completion of a new dock at our Corpus Christi North Beach terminal and a crude oil pipeline that was placed in service in the third quarter of 2013;

• | an increase in revenues of $2.1 million and an increase in throughputs of 7,901 barrels per day on the East Pipeline due to strong demand for distillates in the regions served by the East Pipeline; and

• | an increase in revenues of $1.3 million, while aggregate throughputs remained flat, on crude oil pipelines serving the Ardmore refinery due to increased volumes under a higher tariff.

The higher revenues and throughputs were partially offset by a decrease in revenues of $2.1 million and a decrease in throughputs of 14,674 barrels per day on crude oil pipelines serving the McKee refinery due to a turnaround at the McKee refinery during the first quarter of 2014.
Operating expenses decreased $5.8 million for the three months ended March 31, 2014, compared to the three months ended March 31, 2013, primarily due to decreased rental costs associated with our South Texas crude oil pipelines, acquired in late 2012, and decreased payroll-related costs.
Depreciation and amortization expense increased $2.4 million for the three months ended March 31, 2014, compared to the three months ended March 31, 2013, mainly due to the completion of various projects that serve Eagle Ford Shale production.
Storage
Throughput revenues increased $5.1 million and throughputs increased 151,734 barrels per day for the three months ended March 31, 2014, compared to the three months ended March 31, 2013. Revenues increased $3.8 million and throughputs increased 54,390 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 a new dock. Also, revenues increased $2.1 million and throughputs increased 117,677 barrels per day as a result of turnarounds and operational issues during the first quarter of 2013 at the refineries served by our Corpus Christi and Texas City crude oil storage tank facilities.
Storage lease revenues decreased $14.2 million for the three months ended March 31, 2014, compared to the three months ended March 31, 2013, primarily due to:

• | a decrease of $15.5 million, mostly at our West Coast terminals, as a result of reduced demand, resulting in lower throughputs, handling fees and storage fees. Also, a narrowing price differential on two traded crude oil grades (WTI and LLS) reduced profit sharing on one of our unit trains at our St. James terminal; and

• | a decrease of $4.6 million at our St. Eustatius terminal facility, mainly due to idle tankage during January and February prior to being leased in March 2014.

The declines in storage lease revenues were partially offset by an increase of $5.0 million in storage lease revenues resulting from another completed unit train offloading facility at our St. James terminal.
Depreciation and amortization expense increased $2.2 million for the three months ended March 31, 2014, compared to the three months ended March 31, 2013, primarily due to the completion of various projects at our St. James terminal.
Fuels Marketing
Sales and cost of product sales decreased $152.0 million and $159.3 million, respectively, resulting in an increase in total gross margin of $7.2 million for the three months ended March 31, 2014, compared to the three months ended March 31, 2013. The increase in total gross margin was primarily due to an increase of $6.6 million in the gross margin from bunker fuel sales, mainly at our Texas City and St. Eustatius facilities. The gross margin at our Texas City facility increased mainly as a result of lower product costs, while the gross margin at our St. Eustatius facility was positively impacted by hedge gains.
Operating expenses decreased $3.9 million for the three months ended March 31, 2014, compared to the three months ended March 31, 2013, primarily as a result of decreased vessel lease and fuel costs from our St. Eustatius bunkering operations.

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 decreased $6.6 million for the three months ended March 31, 2014, compared to the three months ended March 31, 2013, primarily as a result of lower compensation expense associated with our long-term incentive plans, a decrease in salaries and wages and decreased employee benefit costs.
Equity in loss of joint ventures decreased $6.8 million for the three months ended March 31, 2014, compared to the three months ended March 31, 2013, primarily due to the Asphalt JV Sale.
Interest expense, net increased $3.4 million for the three months ended March 31, 2014, compared to the three months ended March 31, 2013, mainly due to the issuance of the $402.5 million of 7.625% fixed-to-floating rate subordinated notes in January 2013, the issuance of $300.0 million of 6.75% senior notes in August 2013 and an increase in the amortization of costs associated with the termination of certain forward-starting interest rate swap agreements in 2013.
Other income, net increased $3.3 million for the three months ended March 31, 2014, compared to the three months ended March 31, 2013, mainly due to changes in foreign exchange rates related to our foreign subsidiaries.
Income tax expense increased $1.0 million for the three months ended March 31, 2014, compared to the three months ended March 31, 2013, mainly due to increased taxable income in U.S. corporate entities.
For the three months ended March 31, 2014, we recorded a loss from discontinued operations of $3.4 million, compared to income from discontinued operations of $4.8 million for the three months ended March 31, 2013. Income from discontinued operations for the three months ended March 31, 2013 includes a gain of $9.3 million related to the San Antonio Refinery Sale.

TRENDS AND OUTLOOK
Overall, we expect our earnings for the second quarter of 2014 to be higher than the second quarter of 2013.
Pipeline Segment
We expect that our pipeline segment earnings for the second quarter of 2014 will exceed the comparable period in 2013 and the first quarter of 2014, mainly due to higher throughputs in the Eagle Ford Shale region. This increase in throughputs is due to continued growth in the region, a completed pipeline expansion project in the third quarter of 2013 and the completion of the expansion of our private dock at our Corpus Christi North Beach terminal in the first quarter of 2014. Both of these expansion projects increased our South Texas crude oil pipeline system’s overall capacity to ship barrels into Corpus Christi.
In the second quarter of 2014, we also expect to benefit from increased throughputs following the completion of another pipeline expansion project in the Eagle Ford Shale region and reduced turnaround activity at our customers’ refineries. We expect full-year earnings for 2014 to exceed 2013 mainly due to the benefit of increased throughputs described above and the July 1, 2014 tariff increase on pipelines regulated by the Federal Energy Regulatory Commission.
Storage Segment
We expect storage segment earnings for the second quarter of 2014 to be lower than the second quarter of 2013, mainly due to lower profit sharing benefits at our St. James, Louisiana terminal resulting from the narrowing of the LLS to WTI spread. We expect our storage segment to continue to benefit from the fourth quarter of 2013 completion of a second rail-car offloading facility at our St. James, Louisiana terminal and from additional storage throughputs associated with the completion of Eagle Ford Shale projects. However, reduced demand and lower profit sharing mentioned above has negatively affected our earnings in the storage segment. Therefore, we expect our second quarter earnings in the storage segment to be comparable to the first quarter of 2014. Also, the full-year earnings for 2014 are expected to be comparable to 2013, excluding the non-cash charges in 2013.
Fuels Marketing Segment
We expect second quarter 2014 results for our fuels marketing segment to be higher than the second quarter of 2013, primarily due to higher projected earnings from our bunker fuel operations. In the third quarter of 2013, we entered into a new bunker fuel supply agreement, which reduced our working capital requirements and allowed us to reduce operating costs. We expect these reduced operating costs to continue to benefit this segment in 2014 as compared to 2013. We expect earnings for the second quarter of 2014 to be lower than the first quarter of 2014 as the first quarter benefited from seasonal increased demand in the cruise line business. Although, we expect the full-year 2014 results in this segment to exceed 2013 results, earnings in this segment, as in any margin-based business, are subject to many factors that can raise or lower margins, which may cause the segment’s actual results to vary significantly from our forecast.
This quarter, we reduced our earnings volatility and working capital requirements though the completion of the sale of our remaining 50% ownership interest in Asphalt JV. We expect our net income for the remainder of 2014 to benefit from positive equity in earnings of joint ventures.
Our outlook for the partnership may change as it is based on our continuing evaluation of a number of factors, including factors outside our control, such as the price of crude oil, the state of the economy and changes to refinery maintenance schedules, that affect demand for crude oil, refined products and ammonia, as well as demand for our transportation and storage services.

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 Asphalt JV, 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, we work 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 those requirements, we utilize other sources of cash flow, which in the past have included borrowings under our $1.5 billion five-year revolving credit agreement (the 2012 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 from external sources, primarily borrowings under the 2012 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, 2013 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 the 2012 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, 2013 describe the risks inherent in our ability to maintain or grow the distribution.
Cash Requirements and Sources in 2014 and 2013. For the year ended December 31, 2013, our cash flow from operations was sufficient to cover our distributions to our partners and our reliability capital expenditures, mainly due to our strategic redirection discussed previously in the Trends and Outlook section in Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2013. For 2014, we currently expect 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, 2014 and 2013
The following table summarizes our cash flows from operating, investing and financing activities:

| Three Months Ended March 31,
| 2014 |  | 2013
| (Thousands of Dollars)
Net cash provided by (used in): |  |  |
Operating activities | $ | 63,325 |  |  | $ | 144,400 |
Investing activities | (76,331 | ) |  | (3,118 | )
Financing activities | (42,702 | ) |  | (107,569 | )
Effect of foreign exchange rate changes on cash | (2,437 | ) |  | (802 | )
Net (decrease) increase in cash and cash equivalents | $ | (58,145 | ) |  | $ | 32,911 |

Net cash provided by operating activities for the three months ended March 31, 2014 was $63.3 million, compared to $144.4 million for the three months ended March 31, 2013. Working capital increased $38.8 million for the three months ended March 31, 2014, compared to a decrease of $73.6 million for the three months ended March 31, 2013. Please refer to the Working Capital Requirements section below for a discussion of the changes in working capital.
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 Asphalt JV under the NuStar Term Loan.

Table of Contents
For the three months ended March 31, 2013, net cash provided by operating activities and proceeds from the San Antonio Refinery Sale were used to fund our distributions to unitholders and our general partner, strategic and reliability capital expenditures and the increase in the note receivable.
Revolving Credit Agreement
As of March 31, 2014, our consolidated debt coverage ratio was 4.4x, and we had $784.0 million available for borrowing. Due to a covenant in our 2012 Revolving Credit Agreement that requires us to maintain, as of the end of any four consecutive fiscal quarters, a consolidated debt coverage ratio not to exceed 5.00-to-1.00, we may not be able to borrow the maximum available amount.
Shelf Registration Statement
On June 18, 2013, the Securities and Exchange Commission declared effective our shelf registration statement on Form S-3, which permits us to offer and sell various types of securities, including NuStar Energy common units and debt securities of NuStar Logistics and NuPOP (the 2013 Shelf Registration Statement). The 2013 Shelf Registration Statement does not have a stated maximum dollar limit.
If the capital markets become more volatile, our access to the capital markets may be limited, or we could face increased costs. In addition, it is possible that our ability to access the capital markets may be limited at a time when we would like or need access, which could have an impact on our ability to refinance maturing debt and/or react to changing economic and business conditions.
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, 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.
During the three months ended March 31, 2013, our reliability capital expenditures totaled $5.7 million, primarily related to maintenance upgrade projects at our terminals. Strategic capital expenditures for the three months ended March 31, 2013 totaled $46.8 million and were primarily related to projects associated with Eagle Ford Shale production in South Texas and projects at our St. James, Louisiana terminal.
For the full year 2014, we expect our capital expenditures to total approximately $385.0 million to $415.0 million, including $35.0 million to $45.0 million for reliability capital projects and $350.0 million to $370.0 million for strategic capital projects, not including acquisitions. We continue to evaluate our capital budget and make changes as economic conditions warrant, and our actual capital expenditures for 2014 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 2014, and our internal growth projects can be accelerated or scaled back depending on the condition of the capital markets.
Working Capital Requirements
Our fuels marketing operations require us to make investments in working capital. Those working capital requirements may vary with fluctuations in the commodity prices of inventory and 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 timing of payments.
Inventories decreased $35.5 million for the three months ended March 31, 2014, primarily as a result of a bunker fuel supply strategy that reduced the inventory carried in our bunker fuel operations. We also reduced inventories associated with our heavy fuel oil trading operations. Accounts payable decreased $93.4 million during the three months ended March 31, 2014, primarily due to timing of payments for crude oil purchases related to Asphalt JV, which corresponds to the decrease in the receivable from related parties of $50.9 million during the three months ended March 31, 2014. The crude oil supply agreement with Asphalt JV terminated effective January 1, 2014. Please refer to Note 8 of the Condensed Notes to Consolidated Financial Statements in Item 1. “Financial Statements” for a more detailed discussion of our agreements with Asphalt JV. Accounts

payable also decreased in our bunker fuel operations due to the timing of payments. Accounts receivable increased $22.8 million, primarily due to increased crude oil trading and bunker fuel sales.
NuStar Term Loan
Effective upon the Asphalt JV Sale, the NuStar JV Facility was converted into the NuStar Term Loan. The NuStar Term Loan will step down from $190.0 million over time: first, to $175.0 million on December 31, 2014 and then to $150.0 million on September 30, 2015. While the NuStar Term Loan does not provide for any other scheduled payments, Asphalt JV is required to use all of its excess cash, as defined in the NuStar Term Loan, to repay the NuStar Term Loan. Like the NuStar JV Facility, the NuStar Term Loan must be repaid in full on September 28, 2019. All repayments of the NuStar Term Loan, including those scheduled in 2014 and 2015, are subject to Asphalt JV meeting certain restrictive requirements contained in its third-party credit facility. Our obligation to provide credit support, such as guarantees, letters of credit and cash collateral, as applicable, of up to $150.0 million, will be reduced by a minimum of $25.0 million beginning February 2016 and will terminate in full no later than September 28, 2019. As of March 31, 2014, we provided guarantees for Asphalt JV with an aggregate maximum potential exposure of $111.0 million, plus two guarantees to suppliers that do not specify a maximum amount, but for which we believe any amounts due would be minimal.
Distributions
The following table reflects the allocation of total cash distributions to the general and limited partners applicable to the period in which the distributions were earned:

| Three Months Ended March 31,
| 2014 |  | 2013
| (Thousands of Dollars, Except Per Unit Data)
General partner interest | $ | 1,961 |  |  | $ | 1,961 |
General partner incentive distribution | 10,805 |  |  | 10,805 |
Total general partner distribution | 12,766 |  |  | 12,766 |
Limited partners’ distribution | 85,285 |  |  | 85,285 |
Total cash distributions | $ | 98,051 |  |  | $ | 98,051 |
Cash distributions per unit applicable to limited partners | $ | 1.095 |  |  | $ | 1.095 |

Distributions declared for the quarter are paid within 45 days following the end of each quarter based on the partnership interests outstanding as of a record date that is set after the end of each quarter. The following table summarizes information related to our quarterly cash distributions:

Quarter Ended |  | Cash Distributions Per Unit |  | Total Cash Distributions (Thousands of Dollars) |  | Record Date |  | Payment Date
March 31, 2014 (a) |  | $ | 1.095 |  |  | $ | 98,051 |  |  | May 7, 2014 |  | May 12, 2014
December 31, 2013 |  | $ | 1.095 |  |  | $ | 98,051 |  |  | February 10, 2014 |  | February 14, 2014

(a) | The distribution was announced on April 23, 2014.

Debt Obligations
We are a party to the following debt agreements as of March 31, 2014:

• | the 2012 Revolving Credit Agreement due May 2, 2017, with a balance of $558.7 million as of March 31, 2014;

• | NuStar Logistics’: 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; and

• | NuStar Logistics’ $365.4 million Gulf Opportunity Zone Revenue Bonds due from 2038 to 2041.

Management believes that, as of March 31, 2014, we are in compliance with all ratios and covenants of the 2012 Revolving Credit Agreement. Our other long-term debt obligations do not contain any financial covenants that are different than those contained in the 2012 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 long-term debt agreements.
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 detailed 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, 2013.

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 the past, we have also utilized forward-starting interest rate swap agreements to lock in the rate on the interest payments related to forecasted debt issuances and fixed-to-floating interest rate swap agreements to manage a portion of the exposure to changing interest rates by converting certain fixed-rate debt to variable-rate debt. Borrowings under the 2012 Revolving Credit Agreement and Gulf Opportunity Zone Revenue Bonds expose us to increases in applicable interest rates.
We had no forward-starting or fixed-to-floating interest rate swap agreements outstanding as of March 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.

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, which was 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.
