We recorded a $5.0gain from business interruption insurance of $4.0 million lossfor the three months ended March 31, 2021, which is included in “Other (expense) income, net”“Operating expenses” in the condensed consolidated statements of comprehensive incomeincome. Insurance proceeds for cleanup costs and business interruption are included in “Cash flows from operating activities” in the third quarterconsolidated statements of 2017 for property damage at our St. Eustatius terminal, which represents the amount of our deductible under ourcash flows. We believe we have adequate insurance policy. Additionally, we incurred approximately $0.7 million of operating expenses to repair minor property damage at several of our domestic terminals. The shutdown of the St. Eustatius terminal also caused lower revenues for our bunker fuel operations in our fuels marketing segment and lower throughput and associated handling fees in our storage segment. We are still evaluating the extent of property damage at our St. Eustatius terminal, as well as the interruption to our operations; therefore, we are unable to estimate the total impact from the hurricanes at this time. However, we expect that losses incurred above our deductible amount will be covered by our insurance policies.offset additional costs.

Navigator Acquisition and Financing Transactions. On May 4, 2017, we completed the acquisition of Navigator Energy Services, LLC for approximately $1.5 billion (the Navigator Acquisition). In order to fund the purchase price, we issued 14,375,000 common units for net proceeds of $657.5 million, issued $550.0 million of 5.625% senior notes for net proceeds of $543.3 million and issued 15,400,000 of our 7.625% Series B Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units (Series B Preferred Units) for net proceeds of $371.8 million. Please refer to Notes 3, 4 and 10 for further discussion.

Axeon Term Loan. On February 22, 2017, we settled and terminated the $190.0 million term loan to Axeon Specialty Products, LLC (the Axeon Term Loan), pursuant to which we also provided credit support, such as guarantees, letters of credit and cash collateral, as applicable, of up to $125.0 million to Axeon Specialty Products, LLC (Axeon). We received $110.0 million in settlement of the Axeon Term Loan, and our obligation to provide ongoing credit support to Axeon ceased.

DerivativesAccounting for Convertible Instruments and HedgingContracts in an Entity’s Own Equity
In August 2017,2020, the Financial Accounting Standards Board (FASB) issued amended guidance intended to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. The amended guidance also makes certain targeted improvements to simplify the applicationaccounting for convertible instruments by eliminating certain accounting models for convertible debt instruments and convertible preferred stock, requiring the calculation of current hedge accounting guidance.diluted earnings per unit to include the effect of potential unit settlement for any convertible instruments that may be settled in either cash or units, and amending the disclosure requirements for convertible instruments. The guidance is effective for annual and interim periods beginning after December 15, 2018, with early adoption permitted. Certain of the new requirements should be applied prospectively while others should2021. Amendments may be applied using either a modified retrospective transition method.approach or a fully retrospective approach. We currently expect to adoptadopted the amended guidance on January 1, 2019 and are assessing2022 using the impact of this amended guidance on our financial position, results of operations and disclosures. We plan to provide additional information about the expected financial impact at a future date.

Unit-Based Payments
In May 2017, the FASB issued amended guidance that clarifies when a change to the terms and conditions of a unit-based payment award is accounted for as a modification. Undermodified retrospective approach. While the amended guidance an entity will apply modification accounting if the value, vesting or classification of the unit-based payment award changes. The guidance is effective for annual and interim periods beginning after December 15, 2017, and amendments should be applied prospectively. We will adopt these provisions January 1, 2018, and we dodid not expect the guidance to have a material impact on our financial position, results of operations, or disclosures.disclosures at adoption, changes to the earnings per unit guidance could result in changes to our diluted net income (loss) per common unit. Please refer to Note 10 for additional information.


Defined Benefit PlansReference Rate Reform
In March 2017,2020, the FASB issued guidance intended to provide relief to companies impacted by reference rate reform. The amended guidance that changesprovides optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. The publication of U.S. dollar LIBOR rates for the presentation of net periodic pension cost relatedmost common tenors is expected to defined benefit plans.

As of March 31, 2022, $402.5 million of our variable-rate debt uses LIBOR as other current employee compensation costs, buta benchmark for establishing the remaining componentsinterest rate. In addition, the distribution rate on our 8.50% Series A Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units is a floating rate based on LIBOR, and the distribution rates on our 7.625% Series B and 9.00% Series C Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units convert from fixed rates to floating rates based on LIBOR in June 2022 and December 2022, respectively.

Goodwill
In January 2017,3. DISPOSITION AND IMPAIRMENT

Sale of Point Tupper Terminal. On February 11, 2022, we entered into an agreement to sell the FASB issued amended guidanceequity interests in our wholly owned subsidiaries that simplifiesown our Point Tupper terminal facility in Nova Scotia, Canada (the Point Tupper Terminal Operations) to EverWind Fuels for $60.0 million, plus working capital, which is subject to adjustment. The terminal facility has a storage capacity of 7.8 million barrels and has been included in the accounting for goodwill impairment by eliminating step 2storage segment. We completed the sale on April 29, 2022 and expect to utilize the sales proceeds to reduce debt and thereby improve our debt metrics as part of our strategic plan to strengthen our balance sheet. We compared the carrying value of the goodwill impairment test. Under the amended guidance, goodwill impairment will be measured as the excessPoint Tupper Terminal Operations, which includes $42.2 million in cumulative foreign currency translation losses accumulated since our acquisition of the reporting unit’s carrying value overPoint Tupper terminal facility in 2005, to its fair value notless costs to exceed the carrying amount of goodwill for that reporting unit. The changes are effective for annual and interim periods beginning after December 15, 2019, and amendments should be applied prospectively. Early adoption is permitted for any impairment tests performed after January 1, 2017,sell, and we are currently evaluating whether we will adopt these provisions early. Regardlessrecognized a pre-tax impairment loss of our decision, we do not expect$46.1 million in the guidance to havefirst quarter of 2022, which is presented in "Impairment loss" on the consolidated statement of comprehensive income. We believe that the sales price of $60.0 million provides a material impact on our financial position, results of operations or disclosures.

Definition of a Business
In January 2017, the FASB issued amended guidance that clarifies the definition of a business used in evaluating whether a set of transferred assets and activities constitutes a business. Under the amended guidance, if substantially allreasonable indication of the fair value of the grossPoint Tupper Terminal Operations as it represents an exit price in an orderly transaction between market participants. The sales price is a quoted price for identical assets acquired is concentratedand liabilities in a single identifiable asset or a groupmarket that is not active and, thus, our fair value estimate falls within Level 2 of similar identifiable assets, the setfair value hierarchy.

Table of transferred assets and activities would not represent a business. To be considered a business, the set of assets transferred is also required to include at least one substantive process that together significantly contribute to the ability to create outputs. In addition, the amended guidance narrows the definition of outputs to be consistent with how outputs are described in the new revenue recognition standard. The changes are effective for annual and interim periods beginning after December 15, 2017, and amendments should be applied prospectively. We will adopt these provisions January 1, 2018, and we do not expect the guidance to have a material impact on our financial position, results of operations or disclosures.

Credit Losses
In June 2016,During the FASB issued amended guidance that requiresfirst quarter of 2022, we determined the use of a “current expected loss” modelPoint Tupper Terminal Operations met the criteria to be classified as held for financial assets measured at amortized cost and certain off-balancesale. Accordingly, the consolidated balance sheet credit exposures. Under this model, entities will be required to estimate the lifetime expected credit losses on such instruments based on historical experience, current conditions, and reasonable and supportable forecasts. This amended guidance also expands the disclosure requirements to enable users of financial statements to understand an entity’s assumptions, models and methods for estimating expected credit losses. The changes are effective for annual and interim periods beginning after December 15, 2019, and amendments should be applied using a modified retrospective approach. We currently expect to adopt the amended guidance on January 1, 2020 and are assessing the impact of this amended guidance on our financial position, results of operations and disclosures. We plan to provide additional information about the expected financial impact at a future date.

Leases
In February 2016, the FASB issued amended guidance that requires lessees to recognizereflects the assets and liabilities that arise from most leasesof the Point Tupper Terminal Operations as held for sale as of March 31, 2022. The following table provides the carrying amounts of the major classes of assets and liabilities included in “Assets held for sale” and “Liabilities held for sale” on the consolidated balance sheet.

3. ACQUISITIONS

Navigator Acquisition
On April 11, 2017, we entered into a Membership Interest Purchase and Sale Agreement (the Acquisition Agreement) with FR Navigator Holdings LLC to acquire all of the issued and outstanding limited liability company interests in Navigator Energy Services, LLC (Navigator) for approximately $1.5 billion. We closed on the Navigator Acquisition on May 4, 2017 and funded the purchase price with the net proceeds of the equity and debt issuances described in Notes 4 and 10. We acquired crude oil transportation, pipeline gathering and storage assets located in the Midland Basin of West Texas consisting of: (i) more than 500 miles of crude oil gathering and transportation pipelines with approximately 92,000 barrels per day ship-or-pay volume commitments and deliverability of approximately 412,000 barrels per day; (ii) a pipeline gathering system with more than 200 connected producer tank batteries capable of more than 400,000 barrels per day of pumping capacity covering over 500,000 dedicated acres with fixed fee contracts; and (iii) approximately 1.0 million barrels of crude oil storage capacity with 440,000 barrels contracted to third parties. We collectively refer to the acquired assets as our Permian Crude System. The assets acquired are included in our pipeline segment.

Remaining Performance Obligations
The Navigator Acquisition broadens our geographic footprint by marking our entry into the Permian Basin and complements our existing asset base. We believe the Permian Crude System will provide a strong growth platform that, when coupled with our assets in the Eagle Ford region, serve to solidify our presence in two of the most prolific basins in the United States.

We accounted for the Navigator Acquisition using the acquisition method. The fair value estimates of the assets acquired and liabilities assumed are based on preliminary assumptions, pending the completion of an independent appraisal and other evaluations as information becomes available to us.

In the third quarter of 2017, goodwill increased by approximately $70.0 million due to valuation adjustments to property, plant and equipment and intangible assets.

Subsequently, the maximum allowed consolidated debt coverage ratio may not exceed 5.00-to-1.00 for any rolling period ending on or after June 30, 2018. If we complete one or more acquisitions for aggregate net consideration of at least $50.0 million, our maximum consolidated debt coverage ratio will increase to 5.50-to-1.00 for two rolling periods.

Issuance of 5.625% Senior Notes
On April 28, 2017, NuStar Logistics issued $550.0 million of 5.625% senior notes due April 28, 2027. We used the net proceeds of $543.3 million from the offering to fund a portion of the purchase price for the Navigator Acquisition and to pay related fees and expenses. Theminimum consolidated interest on the 5.625% senior notes is payable semi-annually in arrears on April 28 and October 28 of each year beginning on October 28, 2017. The 5.625% senior notes do not have sinking fund requirements. These notes rank equally with existing senior unsecured indebtedness and senior to existing subordinated indebtedness of NuStar Logistics.

At the option of NuStar Logistics, the 5.625% senior notes may be redeemed in whole or in part at any time at a redemption price, plus accrued and unpaid interest to the redemption date. If we undergo a change of control, followed by a ratings decline within 60 days of a change of control, each holder of the notes may require us to repurchase all or a portion of its notes at a price equal to 101% of the principal amount of the notes, plus any accrued and unpaid interest to the date of repurchase.

Gulf Opportunity Zone Revenue Bonds

The amount of borrowings outstanding under the Receivables Financing Agreement totaled $46.1$72.0 million, asthe weighted-average interest rate related to outstanding borrowings was 1.9% and $132.2 million of September 30, 2017, which isour accounts receivable was included in “Long-term debt” on the consolidated balance sheet.Securitization Program.


Fair Value of Long-Term Debt
5.The estimated fair values and carrying amounts of long-term debt, excluding finance leases, were as follows:
March 31, 2022December 31, 2021
 (Thousands of Dollars)
Fair value$3,222,517 $3,459,153 
Carrying amount$3,115,915 $3,130,625 

We have estimated the fair value of our publicly traded notes based upon quoted prices in active markets; therefore, we determined that the fair value of our publicly traded notes falls in Level 1 of the fair value hierarchy. With regard to our other debt, for which a quoted market price is not available, we have 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 carrying amount includes net fair value adjustments, unamortized discounts and unamortized debt issuance costs.

6. COMMITMENTS, CONTINGENCIES AND CONTINGENCIESUNCERTAINTIES


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. We had an accrual of $1.6accrued $0.9 million and $0.1 million for contingent losses as of September 30, 2017March 31, 2022 and none as of December 31, 2016.2021, respectively. The amount that will ultimately be paid related to such matters 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 assuranceWe evaluate each contingent loss at least quarterly, and more frequently as each matter progresses and develops over time, and we do not believe that the resolution of any particular claim or proceeding, or all matters in the aggregate, would not have a material adverse effect on our results of operations, financial position or liquidity.


COVID-19. Ongoing uncertainty surrounding the COVID-19 pandemic has caused and may continue to cause volatility and could have a significant impact on management’s estimates and assumptions in 2022 and beyond.
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 for which little or no market data exists. We consider counterparty credit risk and our own credit risk in the determination of all estimated fair values.

Product Imbalances.Since we value our assets and liabilities related to product imbalances using quoted market prices in active markets as of the reporting date, we include these product imbalances in Level 1 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 had derivative instruments for which we determined fair value using industry pricing services and other observable inputs, such as quoted prices on an exchange for similar derivative instruments, and we included these derivative instruments in Level 2 of the fair value hierarchy. See Note 7 for a discussion of our derivative instruments.

Interest Rate Swaps.Becausewe 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, we include these interest rate swaps in Level 2 of the fair value hierarchy.

Guarantees. In 2014, we sold our remaining 50% ownership interest in Axeon and agreed to provide them with credit support, such as guarantees, letters of credit and cash collateral, as applicable, of up to $125.0 million. As of December 31, 2016, we provided guarantees totaling $54.1 million, and one guarantee that did not specify a maximum amount. Our estimate of the fair value was based on significant inputs not observable in the market and thus fell within Level 3 of the fair value hierarchy. In conjunction with the termination of the Axeon Term Loan on February 22, 2017 discussed in the following section, our obligation to provide credit support to Axeon ceased.

Fair Value of Financial Instruments
We recognize cash equivalents, receivables, payables and debt in our consolidated balance sheets at their carrying amounts. The fair values of these financial instruments, except for long-term debt, approximate their carrying amounts.

The estimated fair values and carrying amounts of long-term debt, including the current portion, and the Axeon Term Loan were as follows:
 September 30, 2017 December 31, 2016
 Long-term Debt Long-term Debt Axeon Term Loan
 (Thousands of Dollars)

 $110,000
Carrying amount$3,582,606
 $3,014,364
 $110,000

Long-term Debt. 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.

Axeon Term Loan. In December 2016, Lindsay Goldberg LLC, the private investment firm that owned Axeon, informed us that they entered into an agreement to sell Axeon’s retail asphalt sales and distribution business (the Axeon Sale), and we entered into an agreement with Axeon (the Axeon Letter Agreement) to settle and terminate the Axeon Term Loan for $110.0 million upon closing of the Axeon Sale. Therefore, we reduced the carrying amount of the Axeon Term Loan to $110.0 million and reclassified the Axeon Term Loan from “Other long-term assets, net” to “Other current assets” on the consolidated balance sheet as of December 31, 2016. The Axeon Sale closed on February 22, 2017, at which time we received the $110.0 million payment in accordance with the Axeon Letter Agreement. Furthermore, the Axeon Term Loan and our obligation to provide ongoing credit support to Axeon all terminated concurrently on February 22, 2017.

7. DERIVATIVES AND RISK MANAGEMENT ACTIVITIES


We utilize various derivative instruments to manage our exposure to interest rate risk and commodity price risk. Our risk management policies and procedures are designed to monitor interest rates, futures and swap positions and over-the-counter positions, as well as physical commodity volumes, grades, locations and delivery schedules, to help ensure that our hedging activities address our market risks. Derivative financial instruments associated with commodity price risk with respect to our petroleum product inventories and related firm commitments to purchase and/or sell such inventories were not material for any periods presented.
Interest Rate Risk
We arewere a party to certain interest rate swap agreements to manage our exposure to changes in interest rates, which includeincluded forward-starting interest rate swap agreements related to forecasted debt issuances in 2018 and 2020. 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. Under the terms of the swaps, we pay a fixed rate and receive a rate based on the three-month USD LIBOR. These swaps qualifythat qualified as cash flow hedges and we designate them as such.prior to their termination. We recordreclassify the effective portion of mark-to-market adjustments as a component ofrelated to these cash flows hedges that were recorded in “Accumulated other comprehensive income (loss)”loss” (AOCI), and the amount in AOCI will be recognized in into “Interest expense, net” as the underlying forecasted interest payments occur or if the interest payments are probable not to occur. As of September 30, 2017 and December 31, 2016, the aggregate notional amount of forward-starting interest rate swaps totaled $600.0 million.

Commodity Price Risk
We are exposed to market risks related to the volatility of petroleum product prices. In order to reduce the risk of commodity price fluctuations with respect to our petroleum 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 orreclassified losses on cash flow hedges are considered economic hedges, and we record associated gains and losses in net income. Our risk management committee oversees our trading controls and procedures and certain aspectsto “Interest expense, net” 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. We ceased marketing crude oil in the second quarter of 2017 and exited our heavy fuels trading operations in the third quarter of 2017, thereby reducing our overall hedging activity.

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 1.1 million barrels and 4.7 million barrels as of September 30, 2017 and December 31, 2016, respectively. We had $0.3$0.5 million and $1.8$1.3 million of margin deposits as of September 30, 2017for the three months ended March 31, 2022 and December 31, 2016,2021, respectively.

Amendment of Partnership Agreement
In the second quarter of 2017, our general partner amended and restated our partnership agreement in connection with the issuance of the Series B Preferred Units as described below and the Navigator Acquisition to waive up to an aggregate $22.0 million of the quarterly incentive distributions to our general partner for any NS common units issued from the date of the Acquisition Agreement (other than those attributable to NS common units issued under any equity compensation plan) for ten consecutive quarters, starting with the distributions for the second quarter of 2017.

Issuance of Common Units
On April 18, 2017, we issued 14,375,000 common units representing limited partner interests at a price of $46.35 per unit. We used the net proceeds from this offering of $657.5 million, including a contribution of $13.6 million from our general partner to maintain its 2% general partner interest, to fund a portion of the purchase price for the Navigator Acquisition.

Common Limited Partners
We make quarterly distributions to common unitholders of 100% of our “Available Cash,” generally defined as cash receipts less cash disbursements, including distributions to our preferred units, and cash reserves established by the general partner, in its sole discretion. These quarterly distributions are declared and paid within 45 days subsequent to each quarter-end. The common unitholders receive a distribution each quarter as determined by the board of directors, subject to limitation by the distributions in arrears, if any, on our preferred units. In April 2022, our board of directors declared distributions with respect to our common units with respect to distribution rights and rights upon liquidation.for the quarter ended March 31, 2022.


At any time on or after June 15, 2022, we may redeem our Series B Preferred Units, in whole or in part, at a redemption price of $25.00 per unit plus an amount equal to all accumulated and unpaid distributions to, but not including, the date of redemption, whether or not declared. We may also redeem the Series B Preferred Units upon the occurrence of certain rating events or a change of control as defined in our partnership agreement. In the case of the latter instance, if we choose not to redeem the Series B Preferred Units, the preferred unitholders may have the ability to convert the Series B Preferred Units to common units at the then applicable conversion rate. Holders of the Series B Preferred Units have no voting rights except for certain exceptions set forth in our partnership agreement.

Allocations of Net Income
Our partnership agreement sets forth the calculation to be used to determine the amount and priority of cash distributions that the unitholders and general partner will receive. The partnership agreement also contains provisions for the allocation of net income to the unitholders and the general partner. Our net income for each quarterly reporting period is first allocated to the preferred limited partner unitholders in an amount equal to the earned distributions for the respective reporting period and then to the general partner in an amount equal to the general partner’s incentive distribution calculated based upon the declared distribution for the respective reporting period. We allocate the remaining net income or loss among the common unitholders (98%) and general partner (2%), as set forth in our partnership agreement.

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

11.10. NET INCOME (LOSS) PER COMMON UNIT


Basic and diluted net income (loss) per common unit is determined pursuant to the two-class method. Under this method, all earnings are allocated to our common limited partners and participating securities based on their respective rights to receive distributions earned during the period. Participating securities include our general partner interest and restricted units awarded under our long-term incentive plan.

plans. We compute basic net income (loss) per common unit by dividing net income (loss) attributable to common units by the weighted-average number of common units outstanding during the period.

We compute diluted net income (loss) per common unit by dividing net income (loss) attributable to our common limited partnersunits by the sum of (i) the weighted-averageweighted average number of common units outstanding during the period and (ii) the effect of dilutive potential common units outstanding during the period. Dilutive potential common units may include the Series D Preferred Units and contingently issuable performance units awarded under our long-term incentive plan.unit awards.


The following table detailsSeries D Preferred Units contain certain unitholder conversion and redemption features, and we use the calculationif-converted method to calculate the dilutive effect of the conversion or redemption feature that is most advantageous to our Series D preferred unitholders. The effect of the assumed conversion or redemption of the Series D Preferred Units outstanding was antidilutive for each of the three months ended March 31, 2022 and 2021; therefore, we did not include such conversion in the computation of diluted net (loss) income per common unit:unit.

Contingently issuable performance units are included as dilutive potential common units if it is probable that performance measures will be achieved, unless to do so would be antidilutive.

Recent Developments
Hurricane Activity. InOVERVIEW
NuStar Energy L.P. (NYSE: NS) is primarily engaged in the third quartertransportation, terminalling and storage of 2017, partspetroleum products and renewable fuels and the transportation of anhydrous ammonia. Our business is managed under the direction of the Caribbean and Gulfboard of Mexico experienced three major hurricanes. Severaldirectors of NuStar GP, LLC, the general partner of our general partner, Riverwalk Logistics, L.P., both of which are indirectly wholly owned subsidiaries of ours.

Our operations consist of three reportable business segments: pipeline, storage and fuels marketing. As of March 31, 2022, our assets included 9,940 miles of pipeline and 64 terminal and storage facilities, were affected by the hurricanes,which provided approximately 57 million barrels of storage capacity. As described below, on April 29, 2022 we sold our Point Tupper terminal facility with the main impact at our St. Eustatius terminal, which was temporarily shut down. We recorded a $5.0storage capacity of 7.8 million loss in “Other (expense) income, net” in the condensed consolidated statements of comprehensive income in the third quarter of 2017 for property damage at our St. Eustatius terminal, which represents the amount of our deductible under our insurance policy. Additionally, we incurred approximately $0.7 million of operating expenses to repair minor property damage at several of our domestic terminals. The shutdown of the St. Eustatius terminal also caused lower revenues for our bunker fuel operations in our fuels marketing segment and lower throughput and associated handling fees in our storage segment. We are still evaluating the extent of property damage at our St. Eustatius terminal, as well as the interruption to our operations; therefore, we are unable to estimate the total impact from the hurricanes at this time. However, we expect that losses incurred above our deductible amount will be covered by our insurance policies.

Navigator Acquisition and Financing Transactions. On May 4, 2017, we completed the acquisition of Navigator Energy Services, LLC for approximately $1.5 billion (the Navigator Acquisition). In order to fund the purchase price, we issued 14,375,000 common units for net proceeds of $657.5 million, issued $550.0 million of 5.625% senior notes for net proceeds of $543.3 million and issued 15,400,000 of our 7.625% Series B Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units (Series B Preferred Units) for net proceeds of $371.8 million. We collectively refer to the acquired assets as our Permian Crude System. The assets acquired are included in our pipeline segment. Please refer to Notes 3, 4 and 10 of the Condensed Notes to Consolidated Financial Statements in Item 1. “Financial Statements” for further discussion.

Axeon Term Loan. On February 22, 2017, we settled and terminated the $190.0 million term loan to Axeon Specialty Products, LLC (the Axeon Term Loan), pursuant to which we also provided credit support, such as guarantees, letters of credit and cash collateral, as applicable, of up to $125.0 million to Axeon Specialty Products, LLC (Axeon). We received $110.0 million in settlement of the Axeon Term Loan, and our obligation to provide ongoing credit support to Axeon ceased. Please refer to Note 6 of the Condensed Notes to Consolidated Financial Statements in Item 1. “Financial Statements” for further discussion of the Axeon Term Loan and credit support.

Operations
barrels. We conduct our operations through our subsidiaries, primarily NuStar Logistics, L.P. (NuStar Logistics) and NuStar Pipeline Operating Partnership L.P. (NuPOP). We generate revenue primarily from:
tariffs for transportation through our pipelines;
fees for the use of our terminal and storage facilities and related ancillary services; and
sales of petroleum products.

The following factors affect the results of our operations:
economic factors and price volatility;
industry factors, such as changes in the prices of petroleum products that affect demand or production, or regulatory changes that could increase costs or impose restrictions on operations;
factors that affect our customers and the markets they serve, such as utilization rates and maintenance turnaround schedules of our refining company customers and drilling activity by our crude oil production customers;
18


Table of Contents
company-specific factors, such as facility integrity issues, maintenance requirements and outages that impact the throughput rates of our assets; and
seasonal factors that affect the demand for products transported by and/or stored in our assets and the demand for products we sell.

Recent Developments
Sale of Point Tupper Terminal. On April 29, 2022, we sold the equity interests in our wholly owned subsidiaries that own our Point Tupper terminal facility (the Point Tupper Terminal Operations) to EverWind Fuels for $60.0 million, plus working capital, which is subject to adjustment. The terminal facility has a storage capacity of 7.8 million barrels and has been included in the storage segment. We recognized a non-cash pre-tax impairment loss of $46.1 million in the first quarter of 2022 and expect to utilize the sales proceeds to reduce debt and thereby improve our debt metrics. Please refer to Note 3of the Condensed Notes to Consolidated Financial Statements in Item 1. “Financial Statements” for additional information.

Debt Amendments. On January 28, 2022, we amended and restated our $1.0 billion unsecured revolving credit agreement to extend the maturity to April 27, 2025, replace the LIBOR-based interest rate and modify other terms. Also on January 28, 2022, we amended our $100.0 million receivables financing agreement to extend the scheduled termination date to January 31, 2025, replace the LIBOR-based interest rate and modify other terms.

Other Events
Eastern U.S. Terminals Disposition. On October 8, 2021, we completed the sale of nine U.S. terminal and storage facilities, including all our North East Terminals and one terminal in Florida (the Eastern U.S. Terminal Operations) to Sunoco LP for $250.0 million in cash (the Eastern U.S. Terminals Disposition). The terminals had an aggregate storage capacity of 14.8 million barrels and were included in the storage segment. We utilized the proceeds from the sale to reduce debt and improve our debt metrics.

Trends and Outlook
While 2022 marks the third year of the COVID-19 pandemic in the U.S., we continue to see signs of stabilization and improvement, across the U.S. and in NuStar’s footprint. U.S. refined product demand outlook has seen some sustained improvement, as COVID-19 vaccinations have continued to allow more people go about normal day-to-day activities and traveling. However, variants may emerge that could significantly increase COVID-19 case counts, which may further impact the overall demand recovery in 2022.

Since Russia’s military invasion of Ukraine in late February 2022, prices for a number of the commodities produced in those countries, including oil and gas, rose sharply and have been volatile, on market concerns about worldwide supply constraints. The long-term impact of the ongoing Russia-Ukraine conflict, along with the lingering impact of COVID-19, on the global and U.S. economy remains uncertain; however, at this time, we do not expect a significant impact to our operations or financial position.

Although U.S. oil production has been slow to respond to the recent increase in crude oil prices due to a variety of factors, including supply chain challenges, we expect sustained healthy U.S. shale production growth in 2022 from improving global demand as well as supply constraints from the Russia-Ukraine conflict. We expect our Permian system volumes to see healthy growth in 2022. Refined product demand on NuStar’s pipeline systems rebounded in 2021 to pre-pandemic levels or higher, and we expect our refined products pipeline systems to perform at or above 100% of our pre-pandemic levels through 2022; however, if prices for motor fuels continue to rise and remain at those levels for a sustained period, consumer demand could fall, which would reduce demand for the transportation and storage services we provide. So far this year, the sustained recovery in refined product demand has increased U.S. refiners’ utilization and demand for crude oil, which has contributed to increased throughputs on certain of our crude oil pipelines, which we expect to continue through 2022. In addition, we continue to expect to benefit from the growth of our renewable fuels distribution system on the West Coast, where we expect to provide an increasing share of California’s renewable fuels as we complete our planned tank conversion projects.

The lingering impact of the COVID-19 pandemic continues to ripple through the U.S. economy, notably in the form of rising inflation and supply chain issues, which affected certain industries and geographic areas to varying degrees during 2021; the Russia-Ukraine conflict seems to have only amplified inflation and supply chain constraints so far in 2022. The U.S. Federal Reserve has raised interest rates and is expected to implement several more increases in 2022, which will increase the cost of our variable-rate debt. In addition, the distribution rates of our Series A, B and C Preferred Units have converted, or will convert in 2022, from fixed rates to floating rates that increase or decrease with prevailing interest rates. On the other hand, our ability to pass along rate increases reflecting changes in producer and/or consumer price indices to our customers, under our tariffs and contracts, should counterbalance the impact of inflation on our costs. We plan to continue to manage our operations with fiscal discipline and to evaluate our capital expenditures as we remain committed to improving our debt metrics and strengthening our balance sheet. We expect to continue to fund all of our expenses, distribution requirements and capital expenditures for the full-year 2022 using internally generated cash flows.

Our operationsoutlook for the partnership, both overall and for any of our segments, may change, as we base our expectations on our continuing evaluation of several factors, many of which are outside our control. These factors include, but are not limited to, uncertainty surrounding the COVID-19 pandemic and the Russia-Ukraine conflict; uncertainty surrounding future production decisions by the Organization of Petroleum Exporting Countries and other oil-producing nations (OPEC+); the state of the economy and the capital markets; changes to our customers’ refinery maintenance schedules and unplanned refinery downtime; crude oil prices; the supply of and demand for petroleum products, renewable fuels and anhydrous ammonia; demand for our transportation and storage services; the availability and costs of personnel, equipment, supplies and services essential to our operations; the ability to obtain timely permitting approvals; and changes in laws and regulations affecting our operations.

Consolidated Overview. Net income decreased $29.9 million for the three months ended March 31, 2022, compared to the three months ended March 31, 2021, mainly due to a non-cash pre-tax impairment loss of $46.1 million recorded in the first quarter of 2022 related to our Point Tupper Terminal Operations and lower operating income from our storage segment, excluding the impairment loss. These decreases were partially offset by higher operating income from our pipeline segment.

Corporate Items.General and administrative expenses increased $2.6 million for the three months ended March 31, 2022, compared to the three months ended March 31, 2021, mainly due to higher compensation costs.

Interest expense, net, decreased $5.1 million for the three months ended March 31, 2022, compared to the three months ended March 31, 2021, primarily due to lower overall debt balances following the repayment of outstanding debt, partially with the proceeds from October 2021 and December 2020 asset sales.

Other income, net increased $3.3 million for the three months ended March 31, 2022, compared to the three months ended March 31, 2021, primarily due to foreign exchange rate fluctuations.

Pipeline Segment
As of March 31, 2022, our pipeline assets consist of three reportable business segments:9,940 miles of pipeline with 33 terminals and 13.0 million barrels of storage and fuels marketing.

Pipeline. We own 3,140capacity. Our Central West System includes 3,205 miles of refined product pipelines and 1,8302,235 miles of crude oil pipelines and gathering lines, as well as approximately 5.0 million barrels of storage capacity, which comprisepipelines. In addition, our Central West System. In addition, we own 2,370East System includes 2,500 miles of refined product pipelines, consisting of the East and North Pipelines, and a 2,000-mile ammonia pipeline (the Ammonia Pipeline), which together comprise our Central East System. The East and North Pipelines have storage capacity of approximately 6.7 million barrels.. We charge tariffs on a per barrel basis for transporting refined products, crude oil and other feedstockstransportation in our refined product and crude oil pipelines and on a per ton basis for transporting anhydrous ammoniatransportation in the Ammonia Pipeline. Other revenues include product sales of surplus pipeline loss allowance (PLA) volumes.

Pipeline segment revenues increased $19.5 million and throughputs increased 262,280 barrels per day for the three months ended March 31, 2022, compared to the three months ended March 31, 2021. The results for the first quarter of 2021 were negatively affected by Winter Storm Uri, which brought snow and damaging ice and caused widespread power outages in Texas and surrounding states in February 2021, as well as the lingering effects from the COVID-19 pandemic, as demand did not recover to pre-pandemic levels until the second quarter of 2021. Revenues and throughputs increased primarily due to the following:
an increase in revenues of $13.2 million and an increase in throughputs of 118,660 barrels per day on our Permian Crude System, mainly due to the negative impacts on the first quarter of 2021 described above, as well as an increase of $4.9 million in sales of PLA volumes in the first quarter of 2022 compared to the first quarter of 2021;
an increase in revenues of $2.9 million and an increase in throughputs of 12,516 barrels per day on our North and East pipelines combined, due to supply disruptions from the conversion of a Wyoming refinery, resulting in higher volumes on our East Pipeline and a rebound in demand in 2022, compared to lower demand in 2021 due to the lingering impacts from COVID-19;
an increase in revenues of $1.5 million and an increase in throughputs of 14,183 barrels per day on our McKee System pipelines, mainly due to the negative impacts in the first quarter of 2021 described above;
an increase in revenues of $1.4 million and an increase in throughputs of 15,090 barrels per day on our Three Rivers System, primarily due to an increase in demand on our Nuevo Laredo and San Antonio pipelines;
an increase in revenues of $1.1 million and an increase in throughputs of 13,899 barrels per day on our Houston Pipeline due to a new contract with a customer that began at the end of March 2021; and
although revenues remained comparable as a result of minimum volume commitments, throughputs increased 65,421 barrels per day on our Corpus Christi Crude Pipeline System, mainly due to a rebound in demand.

These increases were partially offset by a decrease in revenues of $1.3 million on our Ardmore System, despite an increase in throughputs of 22,227 barrels per day. Revenues decreased mainly due to the expiration of a customer contract at the end of the first quarter of 2021, while throughputs increased primarily due to the negative impacts in the first quarter of 2021 described above.

Operating expenses increased $3.0 million for the three months ended March 31, 2022, compared to the three months ended March 31, 2021, mainly due to an increase in power costs of $2.5 million, primarily due to higher throughputs.

Storage. We own terminals Segment
Our storage segment is comprised of our facilities that provide storage, handling and other services for refined products, crude oil, specialty chemicals, renewable fuels and other liquids. As of March 31, 2022, we owned and operated 29 terminal and storage facilities in the United States,U.S., one terminal in Nuevo Laredo, Mexico and one terminal located in Point Tupper, Canada, Mexico, the Netherlands, including St. Eustatius in the Caribbean, and the United Kingdom (UK), with approximately 84.7an aggregate storage capacity of 44.2 million barrels of storage capacity.barrels. Revenues for the storage segment include fees for tank storage agreements, wherebyunder which a customer agrees to pay for a certain amount of storage in a tank over a period of time (storage terminal revenues), and throughput agreements, wherebyunder which a customer pays a fee per barrel for volumes movingmoved through our terminals (throughput terminal revenues).


Sale of Point Tupper Terminal. In the first quarter of 2022, we recorded a non-cash pre-tax impairment loss of $46.1 million related to our Point Tupper terminal facility, which was sold on April 29, 2022 for $60.0 million.

Throughput terminal revenues increased $1.6 million for the three months ended March 31, 2022, compared to the three months ended March 31, 2021, primarily due to an increase in revenues of $1.4 million at our Corpus Christi North beach terminal.

Storage terminal revenues decreased $22.3 million for the three months ended March 31, 2022, compared to the three months ended March 31, 2021, primarily due to the following:
a decrease in revenues of $16.3 million due to the Eastern U.S. Terminals Disposition in October 2021; and
a decrease in revenues of $5.5 million and $1.1 million at our St. James and Point Tupper terminals, respectively, mainly due to the expiration of customer contracts.

Operating expenses decreased $3.9 million for the three months ended March 31, 2022, compared to the three months ended March 31, 2021, primarily due to a decrease in operating expenses of $9.3 million due to the Eastern U.S. Terminals Disposition in October 2021. This decrease was partially offset by an increase in maintenance and regulatory expense of $1.0 million in 2022 and a $4.0 million recovery in the first quarter of 2021 for business interruption insurance related to the Selby terminal.

Depreciation and amortization expense decreased $5.1 million for the three months ended March 31, 2022, compared to the three months ended March 31, 2021, mainly due to the Eastern U.S. Terminals Disposition in October 2021.

Fuels Marketing. Within our Segment
The fuels marketing segment includes our bunkering operations we purchase petroleum products for resale.in the Gulf Coast, as well as certain of our blending operations associated with our Central East System. The results of operations for the fuels marketing segment depend largely on the margin between our costs 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 operations of the pipeline and storage segments. We enter into derivative contracts to attempt to mitigate the effects of commodity price fluctuations.

We ceased marketing crude oil in The financial impacts of the second quarter of 2017 and exited our heavy fuels trading operations in the third quarter of 2017. These actions are in linederivative financial instruments associated with our goal of reducing our exposure to commodity margins, and instead focusing on our core, fee-based pipeline and storage segments. Going forward, the only operations remaining in our fuels marketing segment will be our bunkering operations at our St. Eustatius and Texas City terminals, as well as our butane blending operations.

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;
economic factors, such as commodity price volatility that impact our fuels marketing segment and the drilling activity by our crude oil production customers; andrisk were not material for any periods presented.
factors that impact the operations served by our pipeline and storage assets, such as utilization rates and maintenance turnaround schedules of our refining company customers and drilling activity by our crude oil production customers.

Current Market Conditions
The price of crude oil has recovered only modestly since its sharp initial decline in 2014 and subsequent historic lows during 2015 and 2016. This year, global supply and demand have moved into balance, which seems to have reduced crude price volatility, but crude prices remain stalled at approximately 50% of their 2014 levels. Most energy industry experts now project only modest price recovery through the end of 2018.

Table of Contents

Increases or decreases in the price of crude oil affect sectors across the energy industry, including our customers in crude oil production, refining and trading, in different ways at different points in any given price cycle. For example, U.S. crude oil producers reduced their capital spending relatively early in this sustained low price cycle, which reduced drilling activity and lowered production, particularly in shale play regions with higher relative drilling costs. As this cycle has continued, producers focused their trimmed-back spending on the most capital-efficient regions, such as, notably, the Permian Basin. Refiners, on the other hand, have benefitted from lower crude oil prices, to the extent they have been able to take advantage of the combination of lower feedstock prices, especially those positioned for healthy regional demand for their refined products; however, as refined product inventories increase, refiners are incentivized to reduce their production levels, which in turn may reduce their ability to benefit from low crude prices. Crude oil traders focus less on the current market commodity price than on whether that price is higher or lower than future market prices: if the future price for a product is believed to be higher than the current market price, or a “contango market,” traders are more likely to purchase and store products to sell in the future at the higher price. On the other hand, when the current price of crude oil nears or exceeds the expected future market price, or “backwardation,” as is currently the case, traders are no longer incentivized to purchase and store product for future sale.

Pipeline
Total revenues increased $14.9 million and throughputs increased 286,001 barrels per day for the three months ended September 30, 2017, compared to the three months ended September 30, 2016, primarily due to:
an increase in revenues of $15.7 million and an increase in throughputs of 282,145 barrels per day resulting from our Permian Crude System acquired in the Navigator Acquisition;
an increase in revenues of $1.9 million and an increase in throughputs of 4,998 barrels per day due to maintenance downtime in 2016 on a portion of the Ammonia Pipeline, as well as operational issues in 2016 at certain plants served by the pipeline; and
an increase in revenues of $1.7 million and an increase in throughputs of 5,162 barrels per day due to increased production at the refinery served by our North Pipeline.

These increases were partially offset by:
a decrease in revenues of $2.1 million and a decrease in throughputs of 15,995 barrels per day due to a turnaround and operational issues at the refineries served by the East Pipeline in the third quarter of 2017;
a decrease in revenues of $1.9 million and a decrease in throughputs of 3,113 barrels per day due to operational issues at the refinery served by our McKee Systems; and
a decrease in revenues of $0.5 million and a decrease in throughputs of 7,126 barrels per day on our Eagle Ford System mainly due to reduced production in this sustained low crude oil price environment.

Operating expenses remained flat for the three months ended September 30, 2017, compared to the three months ended September 30, 2016. Increased operating expenses of $3.6 million resulting from our recently acquired Permian Crude System were offset by a decrease of $2.4 million in maintenance and regulatory expenses and a decrease of $1.2 million from product imbalances on the East Pipeline.

Depreciation and amortization expense increased $12.6 million for the three months ended September 30, 2017, compared to the three months ended September 30, 2016, mainly due to our acquisition of the Permian Crude System.

Storage
Beginning January 1, 2017, our agreements for our refinery crude storage tanks at Corpus Christi, TX, Texas City, TX and Benicia, CA changed from throughput-based to storage-based. Excluding the effect from the change to these agreements, throughput terminal revenues would have increased $1.6 million and throughputs would have decreased 24,525 barrels per day for the three months ended September 30, 2017, compared to the three months ended September 30, 2016. Throughput terminal revenues increased $3.3 million, despite decreased throughputs of 9,780 barrels per day, at our Corpus Christi North Beach terminal, mainly resulting from our acquisition of assets from Martin Operating Partnership L.P. in December 2016 (the Martin Terminal Acquisition). The benefit of the Martin Terminal Acquisition was partially offset by lower revenues and throughputs resulting from a decrease in Eagle Ford Shale crude oil being shipped to Corpus Christi. Also, revenues decreased $1.6 million and throughputs decreased 32,439 barrels per day at our Paulsboro, NJ terminal as a customer diverted barrels to other terminals.

Excluding the effect of the change to the refinery storage tank agreements described above, storage terminal revenues would have decreased $0.4 million for the three months ended September 30, 2017, compared to the three months ended September 30, 2016, primarily due to:
a decrease of $4.4 million in domestic revenues, mainly at our St. James, LA terminal due to reduced unit train activity and at our Texas City, TX terminal as a result of the exit from our heavy fuels trading operations and tanks out of service; and
a decrease in revenues of $1.3 million at our Point Tupper terminal mainly due to a loss in customer base, tanks out of service and lower reimbursable revenues.

These decreases were mostly offset by an increase in revenues of $4.7 million at our St. Eustatius terminal, mainly due to new customer contracts and rate escalations, partially offset by decreased lower throughput and associated handling fees as a result of the shutdown of the terminal and damage caused by hurricane activity in the third quarter of 2017.

Operating expenses decreased $3.1 million for the three months ended September 30, 2017, compared to the three months ended September 30, 2016, mainly due to:
a decrease of $2.0 million in reimbursable expenses mainly at our Texas City, TX and Point Tupper terminals, consistent with the decrease in reimbursable revenues;
a decrease of $1.4 million in maintenance and regulatory expenses, spread across various terminals; and
a decrease of $1.1 million in internal overhead expenses,March 31, 2021, mainly due to higher capitalized overhead related to capital storage projects in 2017.

Table of Contents

These decreases were partially offset by an increase in operating expenses of $1.8 million resulting from the Martin Terminal Acquisition.

Depreciation and amortization expense increased $2.5 million for the three months ended September 30, 2017, compared to the three months ended September 30, 2016, as a result of the Martin Terminal Acquisition and the completion of various storage projects.

Fuels Marketing
Segment operating loss increased $1.2 million for the three months ended September 30, 2017, compared to the three months ended September 30, 2016, mainly due to lower gross margins from our bunker fuel operations at our St. Eustatius terminal, as well as the temporary shutdownbunkering operations. We received a credit loss recovery of the terminal caused by hurricane activity$1.7 million in the thirdfirst quarter of 2017.2021, which is included in “Operating expenses.”


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 $2.0 million for the three months ended September 30, 2017, compared to the three months ended September 30, 2016, primarily due to a reduction in employee benefit costs.

Interest expense, net increased $10.2 million for the three months ended September 30, 2017, compared to the three months ended September 30, 2016, mainly due to the issuance of $550.0 million of 5.625% senior notes in April 2017. Interest expense also increased as a result of lower interest income due to the termination of the Axeon Term Loan in February 2017. Please refer to Note 6 of the Condensed Notes to Consolidated Financial Statements in Item 1. “Financial Statements” for a discussion of the Axeon Term Loan and related credit support.

For the three months ended September 30, 2017, we recognized other expense, net of $5.1 million mainly due to property damage at our St. Eustatius terminal resulting from hurricane activity in the third quarter of 2017.

Income tax expense increased $0.6 million for the three months ended September 30, 2017, compared to the three months ended September 30, 2016, primarily due to an increase in the margin tax in Texas as a result of the Navigator Acquisition.

Pipeline
Total revenues increased $22.5 million and total throughputs increased 143,671 barrels per day for the nine months ended September 30, 2017, compared to the nine months ended September 30, 2016, primarily due to:
an increase in revenues of $25.1 million and an increase in throughputs of 151,481 barrels per day from our recently acquired Permian Crude System;
an increase in revenues of $6.7 million and an increase in throughputs of 5,130 barrels per day due to maintenance downtime in 2016 on a portion of the Ammonia Pipeline, as well as operational issues in 2016 at certain plants served by the pipeline;
an increase in revenues of $2.6 million, despite a decrease in throughputs of 3,247 barrels per day, on our East Pipeline due to the completion of various storage projects along the pipeline, as well as an increase in long-haul deliveries resulting in higher average tariffs. A turnaround and operational issues at the refineries served by the East Pipeline in the third quarter of 2017 contributed to the decrease in throughputs; and
an increase in revenues of $2.1 million and an increase in throughputs of 21,781 barrels per day due to increased production at the refinery served by the Ardmore System in 2017, as well as a result of a turnaround and operational issues at the refinery in 2016.

These increases were partially offset by a decrease in revenues of $7.2 million and a decrease in throughputs of 10,115 barrels per day due to a turnaround in the second quarter of 2017 at the refinery served by the North Pipeline. Revenues decreased $6.1 million due to a decrease in throughputs of 24,078 barrels per day on our Eagle Ford System mainly due to reduced production in this sustained low crude oil price environment.

Operating expenses increased $4.2 million for the nine months ended September 30, 2017, compared to the nine months ended September 30, 2016. Operating expenses increased $6.3 million as a result of our acquisition of the Permian Crude System, which was partially offset by a decrease of $2.0 million from product imbalances on the East Pipeline.

Depreciation and amortization expense increased $26.0 million for the nine months ended September 30, 2017, compared to the nine months ended September 30, 2016, due to our acquisition of the Permian Crude System and the completion of various pipeline projects.

Storage
Beginning January 1, 2017, our agreements for our refinery crude storage tanks at Corpus Christi, TX, Texas City, TX and Benicia, CA changed from throughput-based to storage-based. Excluding the effect from the change to these agreements, throughput terminal revenues would have increased $6.0 million and throughputs would have decreased 2,207 barrels per day for the nine months ended September 30, 2017, compared to the nine months ended September 30, 2016. Throughput terminal revenues increased at our Corpus Christi North Beach terminal by $11.3 million due to an increase in throughputs of 15,898 barrels per day, mainly resulting from the Martin Terminal Acquisition. The benefit of the Martin Terminal Acquisition was partially offset by lower revenues and throughputs resulting from a decrease in Eagle Ford Shale crude oil being shipped to Corpus Christi. Revenues increased by $0.3 million and throughputs increased 17,128 barrels per day at our McKee System terminals mainly due to new customer contracts, partially offset by lower additive revenues in 2017. These increases in revenues and throughputs were partially offset by decreased revenues of $5.0 million and decreased throughputs of 32,612 barrels per day at our Paulsboro, NJ terminal as a customer diverted barrels to other terminals.

Storage terminal revenues would have decreased $2.9 million for the nine months ended September 30, 2017, compared to the nine months ended September 30, 2016, excluding the effect of the change to the refinery storage tank agreements described above. Domestic throughput and associated handling fees decreased $5.0 million, mainly at our St. James, LA terminal due to reduced unit train activity and at our Texas City, TX terminal as a result of the exit from our heavy fuels trading operations. Domestic reimbursable revenues decreased $2.5 million, mainly at our Texas City, TX terminal. These decreases were partially offset by an increase in revenues of $4.3 million due to new customer contracts and rate escalations, primarily at our West Coast, North East and St. James, LA terminals.

Storage terminal revenues also increased $5.5 million at our St. Eustatius terminal, mainly due to new customer contracts and rate escalations, partially offset by decreased lower throughput and associated handling fees as a result of the shutdown of the terminal and damage caused by hurricane activity in the third quarter of 2017. This increase was partially offset by a decrease in revenues of $4.6 million at our Point Tupper terminal, mainly resulting from a decrease in customer base, tanks out of service and lower reimbursable revenues.


Table of Contents

Operating expenses decreased $7.4 million for the nine months ended September 30, 2017, compared to the nine months ended September 30, 2016, primarily due to:
a decrease of $5.1 million in reimbursable expenses, mainly at our Texas City, TX and Point Tupper terminals, consistent with the decrease in reimbursable revenues;
a decrease of $4.5 million in maintenance and regulatory expenses primarily at our North East and Point Tupper terminals;
a decrease of $2.4 million in contractor services, mainly at our St. James, LA terminal as a result of reduced unit train activity; and
a decrease of $2.3 million in compensation expenses resulting from changes in our revenue agreements for our crude refinery storage tanks.

These decreases were partially offset by increased operating expenses of $6.5 million as a result of the Martin Terminal Acquisition.

Depreciation and amortization expense increased $6.7 million for the nine months ended September 30, 2017, compared to the nine months ended September 30, 2016, as a result of the Martin Terminal Acquisition and the completion of various storage projects.

Fuels Marketing
Segment operating income increased $3.6 million for the nine months ended September 30, 2017, compared to the nine months ended September 30, 2016, primarily due to a reduction in losses of $5.8 million from our heavy fuels trading operations following our exit of that business in 2017. Segment operating income from our bunker fuel operations decreased $3.4 million, mainly at our St. Eustatius terminal, resulting from lower gross margins and the temporary shutdown of the terminal caused by hurricane activity in the third quarter of 2017.

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 $9.8 million for the nine months ended September 30, 2017, compared to the nine months ended September 30, 2016, primarily due to transaction costs related to the Navigator Acquisition.

Interest expense, net increased $23.9 million for the nine months ended September 30, 2017, compared to the nine months ended September 30, 2016, mainly due to the issuance of $550.0 million of 5.625% senior notes in April 2017 and as a result of fees for a bridge loan commitment to potentially assist with the financing of the Navigator Acquisition. We did not enter into or borrow under the bridge loan. Interest expense also increased as a result of lower interest income due to the termination of the Axeon Term Loan in February 2017. Please refer to Note 6 of the Condensed Notes to Consolidated Financial Statements in Item 1. “Financial Statements” for a discussion of the Axeon Term Loan and related credit support.

For the nine months ended September 30, 2017, we recognized other expense, net of $4.9 million mainly due to property damage at our St. Eustatius terminal resulting from hurricane activity in the third quarter of 2017.

Income tax expense decreased $2.0 million for the nine months ended September 30, 2017, compared to the nine months ended September 30, 2016, primarily due to a reduction in withholding taxes related to certain of our foreign subsidiaries.

TRENDS AND OUTLOOK
As a master limited partnership, our core business strategy is to build long-term unitholder value through stable, consistent growth: to that end, we provide a broad array of logistical solution services to a diverse customer base in sectors across the energy industry with our portfolio of assets positioned in geographic markets around the globe, under primarily fee-based, long-term contractual arrangements. This strategy is intended to mitigate the impact of negative market conditions on our results and position us for the financial health necessary to grow as market conditions improve.

We believe that the fact that we provide both storage and pipeline services, for crude and refined products, to customers across the country and around the world, offers some insulation from the impact of commodity market price fluctuations on our results of operations. Since higher crude oil prices have tended to benefit our producer customers, high prices have also correlated with increased demand for our crude oil pipeline services. On the other hand, lower crude oil prices, when coupled with an industry expectation of higher prices in the future, or a contango market, has historically correlated with increased demand from trading companies for our storage services. In the locations at which our assets are integrated physically with the refineries the assets serve, we believe the results generated by those assets depend to a greater degree on each refinery’s continuing need to receive, store and transport the crude and refined products than on crude or refined product prices.

The Navigator Acquisition broadened our geographic footprint and marked our entry into the Permian Basin, one of the fastest-growing basins in the United States. The Permian Basin currently represents approximately forty percent of all onshore rig activity in the United States, and rig count growth in the Permian continues to outpace all other domestic shale plays. Our Permian Crude System is located in the most economic and highest growth counties in the basin, with some of the lowest break-even values in the United States, and offers our customers access to multiple downstream end-markets. We believe this system provides a strong growth platform in the most prolific basin in the United States. While the addition of the Permian Crude System to our asset portfolio could increase the impact of crude oil prices on our results of operations, we believe that our contracts, many of which are long-term, take-or-pay arrangements for committed storage or throughput capacity, should continue to help to blunt the impact of volatility of crude oil prices on our results of operations.

At the time of the Navigator Acquisition in May, we anticipated that our issuance of common units, senior notes and preferred units to fund the purchase price would increase our ongoing costs of funding our quarterly distribution, as well as our interest expense, but we made the decision to move forward because we believed, and continue to believe, that the Permian Crude System’s future growth will outweigh those costs in the long run.

The Permian Basin and our Permian Crude System have been growing since the acquisition, and we expect that growth to continue, even in a continued low price environment. In contrast, during 2017, our pipeline systems and storage assets outside of the Permian Basin (collectively, our Base Business) have been faced with several unanticipated challenges, on top of the continuing burden of the third year of sustained low crude prices. In September, hurricanes caused damage in the Gulf and significant destruction in the Caribbean. While we successfully prevented severe damage from Hurricane Harvey’s heavy rainfall to our six affected Gulf Coast facilities, Hurricane Irma passed almost directly over our facility at St. Eustatius, which sustained substantial damage inflicted by the storm’s 146-mph winds and 30-foot seas. The facility, which will be fully operational by mid-December, resumed some operations within weeks of the storm, but the repairs will continue into 2018 and beyond. On top of the unanticipated costs of the hurricane damage, our Base Business has also faced significant unanticipated and unplanned turnarounds and downtime at our customers’ refineries in 2017. Further, in the course of our ongoing pipeline integrity program, we identified a 50-mile segment of our ammonia pipeline that we must replace over the next five years. Due to the fact that completing the large, unanticipated reliability project in two years will reduce our overall cost, we plan to complete this project by the end of 2018.

Beyond the challenges to our Base Business that have arisen in 2017, if this current low crude price cycle continues in 2018, our pipeline segment could suffer from decreased throughput in our Base Business pipeline systems. For example, our current committed customers on our South Texas Crude System may decline to renew their commitments as those expire over the next few years and may ship only at lower rates. If backwardation continues into next year, our storage segment results could also decline, due to downward pressure on rates and contract renewals driven by lower demand for capacity, at our St. James terminal and at other locations.

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. These factors include, but are not limited to, the state of the economy and the capital markets, changes to our customers’ refinery maintenance schedules and unplanned refinery downtime, crude oil prices, the supply of and demand for crude oil, refined products and anhydrous ammonia, demand for our transportation and storage services and changes in laws or regulations affecting our assets.

LIQUIDITY AND CAPITAL RESOURCES
OverviewOVERVIEW
Our primary cash requirements are for distributions to our partners, debt service, capital expenditures acquisitions and operating expenses. Our partnership agreement requires that we distribute all “Available Cash” to our common limited partners and general partner each quarter, and this termquarter. “Available Cash” is defined in the partnership agreement generally 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.

Each year,directors, subject to requirements for distributions for our objective is to fund our total annual reliability capital expenditures and distribution requirements with our net cash provided by operating activities during that year. If we do not generate sufficient cash from operations to meet that objective, we utilize cash on hand or other sources of cash flow, which in the past have primarily included borrowings under our revolving credit agreement, sales of non-strategic assets and, to the extent necessary, funds raised through equity or debt offerings under our shelf registration statements.preferred units. We have typically funded 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, 2016 describe the risks inherent to these sources of funding and the availability thereof.

During periods when our cash flow from operations is less than our distribution and reliability capital requirements, we may maintain our distribution level because we can utilizewith other sources of Available Cash, as provided in our partnership agreement, including borrowings under our revolving credit agreement and proceeds from the sales of assets.

Prior to 2021, we funded our strategic capital expenditures primarily from borrowings under our revolving credit agreement, funds raised through debt or equity offerings and/or sales of non-strategic assets. However, our ability to raise funds by issuing debt or equity depends on many factors beyond our control. Our risk factors in Item 1A1A. “Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 20162021 describe the risks inherent into these sources of funding and the availability thereof.

In the first quarter of 2022, we continued to prioritize liquidity by extending the maturity on our ability$1.0 billion revolving credit agreement to maintain or growApril 27, 2025, extending the scheduled termination date on our distribution.

$100.0 million receivables financing agreement to January 31, 2025 and entering an agreement to sell our Point Tupper Terminal. For 2017,the full-year 2022, we expect to fund all of our expenses, distribution requirements and capital expenditures using internally generated cash flows as we did for 2021.

Beyond 2022, absent a return of access to the equity capital markets, we plan to continue to fund our expenses, distribution requirements and capital expenditures with internally generated cash flows, which could include proceeds from asset dispositions. We have no long-term debt maturities until 2025, and we have been and expect to continue to be able to access debt capital markets to refinance those maturities. Our Series D Cumulative Convertible Preferred Units (Series D Preferred Units) become redeemable, at our option, beginning in 2023, which coincides with an increase in total cash distributedthe distribution rate of those units. Beginning in 2028, the holders of the Series D Preferred Units have the option to require us to redeem their units, and we have begun taking steps to position ourselves to redeem the Series D Preferred Units gradually over the next several years in advance of the possible mandatory redemption. By reducing our unitholdersleverage, primarily through the disposition of non-strategic assets in recent years, and higher interest costs duecontinuing to increase the amount by which our issuances of debt and equity securities in 2017. See below for additional discussion of our April 2017 equity and debt issuances. However, we expectinternally generated cash flows from operations, combined with a portionexceed our expenses, distribution requirements and capital expenditures, we are increasing our financial flexibility. Beyond those items, we will also continue to evaluate other sources of liquidity to manage the optional or mandatory redemption of the proceeds from the terminationSeries D Preferred Units.

Our working capital decreased $17.5 million for the ninethree months ended September 30, 2016. Although net income decreased,March 31, 2022, compared to a decrease of $24.4 million for the decrease was largely attributablethree months ended March 31, 2021. Working capital requirements are mainly affected by our accounts receivable and accounts payables balances, which vary depending on the timing of payments. Cash flows from operating activities for the three months ended March 31, 2021 include $20.5 million related to non-cash expenses. cleanup costs and business interruption for the 2019 Selby terminal fire. Additionally, the timing of payments related to accrued interest payable changed due to the $250.0 million of 4.75% senior notes repaid on November 1, 2021 and the $300.0 million of 6.75% senior notes repaid February 1, 2021.

Beginning with the distribution earned for the second quarter of 2017, our general partner will not receive incentive distributions with respect to these common units.

We continue to evaluate our capital spending forecastbudget and make changes as economic conditions warrant, and our actual capital expenditures for 2017 may increase or decrease from our current projections. We believe we can fund our currently expected capital expenditures with cash on hand, combined with the sources of liquidity previously described. Our internal growth projects can be accelerated or scaled back depending on market conditions or customer demand. Therefore, our actual capital expenditures for 2022 may increase or decrease from the expected amounts noted above. We expect to self-fund all of our capital expenditures in 2022.

Interest Rate Risk
We manage our exposure to changing interest rates principally through the use of a combination of fixed-rate debt and variable-rate debt. In addition, we utilize forward-starting interest rate swap agreements to lock in the rate on the interest payments related to forecasted debt issuances. Borrowings under our variable-rate debt expose us to increases in interest rates.


On January 28, 2022, we amended and restated our $1.0 billion unsecured revolving credit agreement to extend the maturity to April 27, 2025, replace the LIBOR-based interest rate and modify other terms. Also on January 28, 2022, we amended our $100.0 million receivables financing agreement to extend the scheduled termination date to January 31, 2025, replace the LIBOR-based interest rate and modify other terms. Please refer to Note 75 of the Condensed Notes to Consolidated Financial Statements in Item 1. “Financial Statements” for a more detailed discussion of our interest rate swaps. information.

Distributions on our 8.50% Series A, 7.625% Series B and 9.00% Series C Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units (collectively, the Series A, B and C Preferred Units) are payable out of any legally available funds, accrue and are cumulative from the original issuance dates, and are payable on the 15th day (or the next business day) of each of March, June, September and December of each year to holders of record on the first business day of each payment month. The Series A, B and C Preferred Units expose us to changes in interest rates as the distribution rate on our Series A Preferred Units converted to a floating rate of the applicable LIBOR plus a spread on December 15, 2021, and the distribution rates on our Series B and C Preferred Units convert from fixed rates to floating rates of the applicable LIBOR plus a spread on June 15, 2022 and December 15, 2022, respectively. Based upon the 9,060,000 Series A Preferred Units outstanding at March 31, 2022 and the $25.00 liquidation preference per unit, an increase of 100 basis points, or 1.0%, in interest rates would increase the annual distributions on our Series A Preferred Units by $2.3 million. Please see Note 9 of the Condensed Notes to Consolidated Financial Statements in Item 1. “Financial Statements” for additional information on our Series A, B and C Preferred Units.

Commodity Price Risk
Since the operations of our fuels marketing segment expose us to commodity price risk, we also use derivative instruments to attempt to mitigate the effects of commodity price fluctuations. The derivativeDerivative financial 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 accordanceassociated with our risk management policy, as approved by our board of directors.
We record commodity derivative instruments in the consolidated balance sheets 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.”
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 Statements in Item 1. “Financial Statements”were not material for the volume and related fair value of all commodity contracts.any periods presented.
