ITEMS 1., 1A. and 2. BUSINESS, RISK FACTORS AND PROPERTIES

OVERVIEW

NuStar GP Holdings, LLC (NuStar GP Holdings), a Delaware limited liability company, was formed in June 2000. Our units are traded on the New York Stock Exchange (NYSE) under the symbol “NSH.” Our principal executive offices are located at 19003 IH-10 West, San Antonio, Texas 78257 and our telephone number is (210) 918-2000.

Our only cash generating assets are our ownership interests in NuStar Energy L.P. (NuStar Energy), a publicly traded Delaware limited partnership (NYSE: NS). NuStar Energy is engaged in the transportation of petroleum products and anhydrous ammonia and the terminalling, storage and marketing of petroleum products. NuStar Energy has pipelines in the United States, as well as terminal and storage facilities in the United States, Canada, Mexico, the Netherlands, including St. Eustatius in the Caribbean, and the United Kingdom. As of December 31, 2017 , we have an approximate 13% ownership interest in NuStar Energy, consisting of the following:
the general partner interest;
100% of the incentive distribution rights issued by NuStar Energy, which entitle us to receive increasing percentages of the cash distributed by NuStar Energy, currently at the maximum percentage of 23% ; and
10,214,626 common units of NuStar Energy.

We strive to increase unitholder value by actively supporting NuStar Energy in executing its business strategy, which includes continued growth through expansion projects and strategic acquisitions. We may facilitate NuStar Energy’s growth through the use of our capital resources, which could involve capital contributions, loans or other forms of financial support.

NuStar Energy’s partnership agreement requires that it distribute all available cash to its common limited partners and general partner each quarter, defined in its 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 NuStar Energy’s board of directors. Similarly, we are required by our limited liability company agreement to distribute all of our available cash at the end of each quarter, less reserves established by our board of directors. However, unlike NuStar Energy, we do not have a general partner or incentive distribution rights. Therefore, all of our distributions are made on our units, which are our only class of securities outstanding.

RECENT DEVELOPMENTS

Merger. On February 7, 2018, NuStar GP Holdings, NuStar Energy, Riverwalk Logistics, L.P., NuStar GP, LLC, Marshall Merger Sub LLC, a wholly owned subsidiary of NuStar Energy (Merger Sub), and Riverwalk Holdings, LLC entered into an Agreement and Plan of Merger (the Merger Agreement) pursuant to which Merger Sub will merge with and into NuStar GP Holdings with NuStar GP Holdings being the surviving entity (the Merger), such that NuStar Energy will be our sole member following the merger. Pursuant to the Merger Agreement and at the effective time of the Merger, NuStar Energy’s partnership agreement will be amended and restated to, among other things, (i) cancel the incentive distribution rights, (ii) convert the 2% general partner interest in NuStar Energy into a non-economic management interest and (iii) provide the holders of NuStar Energy’s common units with voting rights in the election of the members of the board of directors of NuStar GP, LLC at an annual meeting, beginning in 2019. The Merger is subject to the satisfaction or waiver of certain conditions, including approval of the Merger Agreement by our unitholders. Additionally, on February 8, 2018, NuStar Energy announced that NuStar Energy’s management anticipates recommending to the board of directors of NuStar GP, LLC, and expects such board of directors to adopt, a reset of NuStar Energy’s quarterly distribution per common unit to $0.60 ($2.40 on an annualized basis), starting with the first-quarter distribution payable in May 2018. We expect to adjust the quarterly distribution to our members accordingly. See Item 1A. “Risk Factors-Risks Related to the Potential Merger.” Please refer to Note 15 of the Notes to Consolidated Financial Statements in Item 8. “Financial Statements and Supplementary Data” for further discussion of the Merger.
NuStar Energy’s Navigator Acquisition and Financing Transactions. On May 4, 2017, NuStar Energy completed the acquisition of Navigator Energy Services, LLC for approximately $1.5 billion (the Navigator Acquisition). In order to fund the purchase price: (i) NuStar Energy issued 14,375,000 common units for net proceeds of $657.5 million , (ii) NuStar Logistics, L.P., a wholly owned subsidiary of NuStar Energy, issued $550.0 million of 5.625% senior notes for net proceeds of $543.3 million and (iii) NuStar Energy issued 15,400,000 of its 7.625% Series B Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units (Series B Preferred Units) for net proceeds of $371.8 million . In conjunction with the Navigator Acquisition, NuStar Energy’s partnership agreement was amended and restated to, among other things, provide a waiver of certain quarterly distributions with respect to our incentive distribution rights. In April 2017, we borrowed approximately $14.0 million under our revolving credit facility to fund a contribution to NuStar Energy in order to maintain our 2% general partner interest in connection with NuStar Energy’s issuance of common units. Please refer to Note 4 of the Notes to Consolidated Financial Statements in Item 8. “Financial Statements and Supplementary Data” for a discussion of these transactions.

RISK FACTORS
RISKS RELATED TO THE POTENTIAL MERGER

The market value of the stated consideration to our unitholders will be determined by the price of NuStar Energy’s common units, the value of which will decrease if the market value of NuStar Energy’s common units decreases, and our unitholders cannot be sure of the market value of NuStar Energy common units that will be issued.
Pursuant to the Merger Agreement, our unitholders will receive approximately 23.6 million NuStar Energy common units as a result of the Merger. The aggregate market value of NuStar Energy’s common units that our unitholders will receive in the Merger will fluctuate with any changes in the trading price of NuStar Energy’s common units. This means there is no “price protection” mechanism contained in the Merger Agreement that would adjust the number of NuStar Energy common units that our unitholders will receive based on any decreases in the trading price of NuStar Energy common units. If NuStar Energy’s common unit price decreases, the market value of the stated consideration received by our unitholders will also decrease. Consider the following example:

Example : Pursuant to the Merger Agreement, our unitholders will receive 0.55 of a NuStar Energy common unit for each NuStar GP Holdings common unit, subject to receipt of cash in lieu of any fractional NuStar Energy common units. Based on the closing sales price of NuStar Energy common units on February 7, 2018 of $31.25 per unit, the market value of all NuStar Energy common units to be received by our unitholders would be approximately $737.50 million. If the trading price for NuStar Energy common units decreased 10% from $31.25 to $28.13 per unit, then the market value of all NuStar Energy common units to be received by our unitholders would be approximately $663.87 million. Accordingly, there is a risk that the premium that existed on February 7, 2018, the last trading day before the public announcement of the Merger, will not be realized by our unitholders at the time the Merger is completed. NuStar Energy common unit price changes may result from a variety of factors, including general market and economic conditions, changes in its business, operations and prospects, and regulatory considerations. Many of these factors are beyond NuStar Energy’s control.

The right of our unitholders to distributions will be changed following the Merger.
Under NuStar Energy’s existing partnership agreement, we are entitled, as the indirect owner of NuStar Energy’s general partner, to receive approximately 2% of all distributions made by NuStar Energy and increasing percentages, up to a maximum of 23%, of the amount of incremental cash distributed by NuStar Energy in respect of the NuStar Energy common units as certain target distribution levels are reached in excess of $0.60 per NuStar Energy common unit in any quarter. After the Merger, assuming the number of units outstanding as of January 31, 2018, the former unitholders of NuStar GP Holdings common units as a group would be entitled to receive approximately 22% of all distributions made by NuStar Energy. As a result of this change, the distributions received by the former unitholders of NuStar GP Holdings could be significantly different.

While the Merger Agreement is in effect, our opportunities to enter into different business combination transactions with other parties on more favorable terms may be limited, and we may be limited in our ability to pursue other attractive business opportunities.
While the Merger Agreement is in effect, we are prohibited from knowingly initiating, soliciting or encouraging the submission of any acquisition proposal or from participating in any discussions or negotiations regarding any acquisition proposal, subject to certain exceptions. As a result of these provisions in the Merger Agreement, our opportunities to enter into more favorable transactions may be limited. Likewise, if we were to sell directly to a third party, we might have received more value with

respect to the general partner interest in us and the incentive distribution rights in NuStar Energy based on the value of NuStar Energy’s business at such time.

Moreover, the Merger Agreement provides for the payment by NuStar GP Holdings of up to $13.7 million in termination fees under specified circumstances, which may discourage other parties from proposing alternative transactions that could be more favorable to our unitholders.

We have also agreed to refrain from taking certain actions with respect to our business and financial affairs pending the consummation of the Merger or termination of the Merger Agreement. These restrictions could be in effect for an extended period of time if the consummation of the Merger is delayed. These limitations do not preclude us from conducting our business in the ordinary or usual course or from acquiring assets or businesses so long as such activity does not have a “material adverse effect,” as such term is defined in the Merger Agreement, or exceed certain thresholds specifically provided in the Merger Agreement.

In addition to the economic costs associated with pursuing the Merger, we will continue to devote substantial time and other human resources to the proposed Merger, which could limit our ability to pursue other attractive business opportunities, including potential joint ventures, stand-alone projects and other transactions. If we are unable to pursue such other attractive business opportunities, then our growth prospects and long-term strategic position following the Merger could be adversely affected.

The Merger is subject to conditions and may not be consummated even if the required NuStar GP Holdings unitholder approvals are obtained.
The Merger is subject to the satisfaction or waiver of certain conditions, some of which are out of the control of NuStar GP Holdings and NuStar Energy, including approval of the Merger Agreement by NuStar GP Holdings unitholders. The Merger Agreement contains other conditions that, if not satisfied or waived, would result in the Merger not occurring, regardless of whether or not the NuStar GP Holdings unitholders have voted in favor of the Merger-related proposals presented to them. Satisfaction of some of these other conditions to the Merger is not entirely in the control of either NuStar GP Holdings or NuStar Energy. In addition, NuStar GP Holdings and NuStar Energy can agree not to consummate the Merger even if all unitholder approvals have been received. The closing conditions to the Merger may not be satisfied, and NuStar GP Holdings and NuStar Energy may choose not to, or may be unable to, waive an unsatisfied condition, which may cause the Merger not to occur.

The Merger Agreement contains provisions granting both NuStar Energy and NuStar GP Holdings the right to terminate the Merger Agreement for certain reasons, including, among others (1) by mutual consent of NuStar Energy and NuStar GP Holdings; (2) by either party if the Merger has not been consummated on or before August 8, 2018; (3) if certain changes in rules or regulations prohibit the consummation of the Merger; (4) if NuStar GP Holdings fails to obtain NuStar GP Holdings unitholder approval; or (5) if a breach of, or an inaccuracy in, the representations or warranties is not cured within thirty days. Furthermore, NuStar Energy may terminate the Merger Agreement in the event that, prior to NuStar GP Holdings unitholder approval, NuStar GP Holdings has intentionally and materially breached the non-solicitation covenants in the Merger Agreement or the NuStar GP Holdings board issues a change of recommendation pursuant to the terms of the Merger Agreement, and NuStar GP Holdings may terminate the Merger Agreement in order to accept a Superior Proposal (as defined in the Merger Agreement) so long as NuStar GP Holdings (1) has not intentionally and materially breached certain provisions of the Merger Agreement and (2) has paid NuStar Energy a termination fee.

Failure to complete the Merger or delays in completing the Merger could negatively impact our common unit price.
If the Merger is not completed for any reason, we may be subject to a number of material risks, including the following:
the price of our common units may decline to the extent that the current market price of these securities reflects a market assumption that the Merger will be completed; and
some costs relating to the Merger, such as certain investment banking fees and legal and accounting fees, must be paid even if the Merger is not completed.

Additionally, on February 8, 2018, NuStar Energy announced that its management anticipates recommending to the board of directors of NuStar GP, LLC, and expects such board to adopt, a reset of NuStar Energy’s quarterly distribution per NuStar Energy common unit to $0.60 ($2.40 on an annualized basis), starting with the first-quarter distribution payable in May 2018. If the Merger is not completed, NuStar Energy’s reset of its quarterly distributions would result in a significant reduction in the amount of cash distributed by NuStar Energy per common unit, including, at a $0.60 quarterly distribution or below, the elimination of any distributions with respect to the incentive distribution rights to us, which could negatively impact our common unit price.

Table of Contents

The costs of the Merger could adversely affect NuStar Energy’s operations and cash flows available for distribution to its unitholders.
The total costs of the Merger, which could be substantial, primarily consist of investment banking, legal counsel and accounting fees, financial printing and other related costs. These costs could adversely affect NuStar Energy’s operations and cash flows available for distributions to NuStar Energy’s unitholders.

If the Merger Agreement were terminated, we may be obligated to pay NuStar Energy for costs incurred related to the Merger. These costs could require us to seek loans or use our available cash that would have otherwise been available for distributions.
Upon termination of the Merger Agreement, and depending upon the circumstances leading to that termination, we could be responsible for reimbursing NuStar Energy for Merger-related expenses that NuStar Energy has paid.

If the Merger Agreement is terminated, the expense reimbursements required by us under the Merger Agreement may require us to seek loans or use cash received from our distributions from NuStar Energy to reimburse these expenses. In either case, reimbursement of these costs could reduce the cash we have available to make quarterly distributions.


RISKS INHERENT IN AN INVESTMENT IN US

Our only cash generating assets are our ownership interests in NuStar Energy. Our cash flows and ability to make distributions at current levels are, therefore, completely dependent upon the ability of NuStar Energy to make cash distributions at current levels to its partners, including us. If NuStar Energy does not make cash distributions at its current levels or reduces the level of cash distributions to its partners, we may not have sufficient cash to pay distributions at our current levels.
Our operating cash flows currently are completely dependent upon NuStar Energy making cash distributions at current levels to its partners, including us. The amount of cash that NuStar Energy can distribute to its partners each quarter principally depends upon the amount of cash it generates from its operations, which fluctuates from quarter to quarter based on, among other things:
throughput volumes transported in its pipelines;
storage contract renewals or throughput volumes in its terminals and storage facilities;
tariff rates and fees it charges and the revenue it realizes for its services;
demand for and supply of crude oil, refined products and anhydrous ammonia;
the effect of worldwide energy conservation measures;
its operating costs;
its costs to comply with environmental, health, safety and security laws and regulations;
weather conditions;
domestic and foreign governmental laws, regulations, sanctions, embargoes and taxes;
prevailing economic conditions; and
the results of its marketing, trading and hedging activities, which fluctuate depending upon the relationship between refined product prices and prices of crude oil and other feedstocks.

In addition, the amount of cash that NuStar Energy will have available for distribution depends on other factors, including:
its debt service requirements and restrictions on distributions contained in its current or future debt agreements;
the sources of cash used to fund its acquisitions;
its capital expenditures;
fluctuations in its working capital needs;
its issuances of debt and equity securities and ability to access the capital markets; and
adjustments in cash reserves made by the board of directors of NuStar GP, LLC, in its discretion.

As discussed above, on February 8, 2018, NuStar Energy announced that its management anticipates recommending to the board of directors of NuStar GP, LLC, and expects such board to adopt, a reset of NuStar Energy’s quarterly distribution per NuStar Energy common unit to $0.60 ($2.40 on an annualized basis), starting with the first-quarter distribution payable in May 2018. In addition, it is possible that one or more of the factors listed above may serve to reduce NuStar Energy’s available cash to such an extent that it could be rendered unable to pay distributions at the current level or at all in a given quarter. Furthermore, cash distributions to NuStar Energy unitholders depend primarily upon cash flows, and not solely on profitability, which is affected by non-cash items, and NuStar Energy may make cash distributions during periods in which it records net losses and may not make cash distributions during periods in which it records net income.

Table of Contents

In the future, we may not have sufficient cash to pay distributions at our current quarterly distribution level or to increase distributions.
Because our only source of operating cash flows consists of cash distributions from NuStar Energy, the amount of distributions we are able to make to our unitholders may fluctuate based on the level of distributions NuStar Energy makes to its unitholders, including us. We cannot assure you that NuStar Energy will continue to make quarterly distributions at its current level of $1.095 per common unit, or any other amount, or increase its quarterly distributions in the future. In addition, while we would expect to increase or decrease distributions to our unitholders if NuStar Energy increases or decreases distributions to us, the timing and amount of such changes in distributions, if any, will not necessarily be comparable to the timing and amount of any changes in distributions made by NuStar Energy to us. Our ability to distribute cash received from NuStar Energy to our unitholders is limited by a number of factors, including:
interest expense and principal payments on any indebtedness we may incur;
restrictions on distributions contained in any future debt agreements;
our general and administrative expenses, including expenses we incur as a public company;
expenses of our subsidiaries, including tax liabilities of our corporate subsidiaries;
reserves necessary for us to make the necessary capital contributions to maintain our general partner interest in NuStar Energy, as required by the partnership agreement of NuStar Energy upon the issuance of certain additional partnership securities by NuStar Energy; and
reserves our board of directors believes prudent for us to maintain for the proper conduct of our business or to provide for future distributions.

We cannot guarantee that in the future we will be able to pay distributions or that any distributions NuStar Energy pays to us will allow us to pay distributions at or above our current quarterly distribution of $0.545 per unit. The actual amount of cash that is available for distribution to our unitholders will depend on numerous factors, many of which are beyond our control or the control of NuStar Energy. Therefore, a reduction in the amount of cash distributed by NuStar Energy per common unit or on the incentive distribution rights, or an increase in our expenses, may result in our not being able to pay our current quarterly distribution of $0.545 per unit. For instance, in connection with NuStar Energy’s acquisition of Navigator Energy Services, LLC in May 2017, NuStar Energy, with our consent, amended and restated its partnership agreement to waive up to an aggregate $22.0 million of the quarterly incentive distributions payable to us for any NuStar Energy common units issued from April 11, 2017 (other than those attributable to NuStar Energy common units issued under any equity compensation plan) for ten consecutive quarters, starting with the distributions for the second quarter of 2017 and, as described above, NuStar Energy has announced an anticipated reset of its quarterly distribution per NuStar Energy common unit to $0.60 per unit.

If the Merger is not consummated, NuStar Energy’s common unitholders, excluding the owner of NuStar Energy’s general partner, have the right to remove NuStar Energy’s general partner by a simple majority vote, which would cause us to divest our general partner interest and incentive distribution rights in NuStar Energy in exchange for cash or common units of NuStar Energy and cause us to lose our ability to manage NuStar Energy.
We currently manage NuStar Energy through Riverwalk Logistics, L.P., NuStar Energy’s general partner and our indirect, wholly owned subsidiary. NuStar Energy’s partnership agreement, however, gives common unitholders of NuStar Energy the right to remove the general partner of NuStar Energy upon the affirmative vote of holders of a majority of outstanding NuStar Energy common units, excluding the common units owned by us. As of December 31, 2017, we owned 10,214,626 common units representing limited partner interests in NuStar Energy, and the public unitholders owned the remaining 82,962,057 outstanding common units representing limited partner interests. If the Merger is not consummated, and if Riverwalk Logistics, L.P. were removed as the general partner of NuStar Energy, it would receive cash or common units in exchange for its general partner interest and its incentive distribution rights and would lose its ability to manage NuStar Energy. While the common units or cash that Riverwalk Logistics, L.P. would receive are intended under the terms of NuStar Energy’s partnership agreement to fully compensate it in the event it is removed as general partner, these common units or the investments made with the cash over time may not provide us with as much distributable cash, or be as valuable, as the general partner interest and incentive distribution rights had we retained them.

NuStar Energy’s general partner, with our consent, may limit or modify the incentive distributions we are entitled to receive in order to facilitate the growth strategy of NuStar Energy. Our board of directors can give this consent without a vote of our unitholders.
We indirectly own NuStar Energy’s general partner, which owns the incentive distribution rights in NuStar Energy that entitle us to receive increasing percentages, up to a maximum of 23%, of any cash distributed by NuStar Energy to common unitholders as it exceeds a distribution of $0.60 per NuStar Energy common unit in any quarter. A substantial portion of the cash flows we receive from NuStar Energy are provided by these incentive distributions. Our limited liability company agreement provides that our board of directors may consent to the elimination, reduction or modification of the incentive distribution rights without our unitholders’ approval if our board determines that the elimination, reduction or modification will not adversely affect our unitholders in any material respect. For example, in connection with NuStar Energy’s acquisition of

Table of Contents

Navigator Energy Services, LLC in May 2017, NuStar Energy, with our consent, amended and restated its partnership agreement to waive up to an aggregate $22.0 million of the quarterly incentive distributions payable to us for any NuStar Energy common units issued from April 11, 2017 (other than those attributable to NuStar Energy common units issued under any equity compensation plan) for ten consecutive quarters, starting with the distributions for the second quarter of 2017.

Restrictions in our credit facility limit our ability to make distributions to our unitholders. Our credit facility matures in June 2018.
Our credit facility contains covenants limiting our ability to incur indebtedness, grant liens, engage in transactions with affiliates and make distributions to our unitholders. The credit facility also contains covenants requiring NuStar Energy to maintain certain financial ratios. Our and NuStar Energy’s ability to comply with any restrictions and covenants may be affected by events beyond our control, including prevailing economic, financial and industry conditions. If we or NuStar Energy are unable to comply with these restrictions and covenants, any indebtedness under our credit facility may become immediately due and payable, and our lenders’ commitment to make loans to us under our credit facility may terminate. We might not have, or be able to obtain, sufficient funds to make these accelerated payments.

Our payment of principal and interest on any future indebtedness will reduce our cash available for distribution on our units. Our credit facility limits our ability to pay distributions to our unitholders during an event of default or if an event of default would result from the distribution.

In addition, this and any future levels of indebtedness may:
adversely affect our ability to obtain additional financing for future operations or capital needs;
limit our ability to pursue acquisitions and other business opportunities; or
make our results of operations more susceptible to adverse economic or operating conditions.

Our revolving credit facility matures in June 2018. It is possible that our lenders may not agree to renew our credit facility or may only agree to renew it on substantially less favorable terms. If our credit facility is renewed on substantially less favorable terms, or if our credit facility is not renewed and we must enter into alternative financing arrangements, various limitations in these financing agreements may reduce our ability to incur additional indebtedness, to engage in some transactions or to capitalize on business opportunities. In the event we are unable to obtain adequate financing and NuStar Energy issues additional units, we may not be able to make contributions to NuStar Energy necessary to maintain our general partner interest.

Our ability to sell our ownership interests in NuStar Energy may be limited by securities laws restrictions and liquidity constraints.
All of the units of NuStar Energy that we own are unregistered, restricted securities within the meaning of Rule 144 under the Securities Act of 1933. Unless we exercise our registration rights with respect to these units, we are limited to selling into the market in any three-month period an amount of NuStar Energy common units that does not exceed the greater of 1% of the total number of common units outstanding or the average weekly reported trading volume of the common units for the four calendar weeks prior to the sale. We face contractual limitations on our ability to sell our general partner interest and incentive distribution rights, and the market for such interests is illiquid.

The market price of our units may be volatile, which could cause you to lose all or part of your investment.
The market price of our units could be subject to significant fluctuations due to a variety of factors outside of our control, and the equity markets in general are subject to volatility that may be unrelated to the operating performance of particular companies. These broad market fluctuations may adversely affect the trading price of our units. In addition, potential investors may be deterred from investing in our units for various reasons, including the very limited number of publicly traded entities whose assets consist almost exclusively of partnership interests in a publicly traded partnership. The lack of liquidity may also contribute to significant fluctuations in the market price of our units and limit the number of investors who are able to buy our units.

The market price of our units could be adversely affected by sales of substantial amounts of our units into public markets, including sales by our existing unitholders.
Sales by us or any of our existing unitholders, including William E. Greehey, Chairman of the Boards of Directors of NuStar GP Holdings and NuStar GP, LLC, of a substantial number of our units in the public markets, or the perception that such sales might occur, could have a material adverse effect on the price of our units or could impair our ability to obtain capital through an offering of equity securities. As of December 31, 2017, Mr. Greehey beneficially owned approximately 21% of our outstanding units.

Distributions on our incentive distribution rights in NuStar Energy are more uncertain than distributions on the common units we hold.
Our indirect ownership of the incentive distribution rights in NuStar Energy entitles us to receive our pro rata share of specified percentages of cash distributions on common units made by NuStar Energy with respect to any particular quarter only in the event that NuStar Energy distributes more than $0.60 per common unit for such quarter. As a result, the holders of NuStar Energy’s common units have a priority over the holders of NuStar Energy’s incentive distribution rights to the extent of cash distributions by NuStar Energy up to and including $0.60 per common unit for any quarter.

Our incentive distribution rights entitle us to receive increasing percentages, up to 23%, of all cash distributed by NuStar Energy on its common units. However, in connection with NuStar Energy’s acquisition of Navigator Energy Services, LLC in May 2017, NuStar Energy, with our consent, amended and restated its partnership agreement to waive up to an aggregate $22.0 million of the quarterly incentive distributions payable to us for any NuStar Energy common units issued from April 11, 2017 (other than those attributable to NuStar Energy common units issued under any equity compensation plan) for ten consecutive quarters, starting with the distributions for the second quarter of 2017. Because the incentive distribution rights with respect to all common units not temporarily subject to the aforementioned waiver currently participate at the maximum 23% target cash distribution level in all distributions made by NuStar Energy at or above the current distribution level with respect to its common units, future growth in distributions we receive from NuStar Energy will not result from an increase in the target cash distribution level associated with the incentive distribution rights.

Furthermore, a decrease in the amount of distributions by NuStar Energy to less than $0.66 per common unit per quarter would reduce our percentage of the incremental cash distributions above $0.60 per common unit per quarter from 23% to 8%. As a result, any such reduction in quarterly cash distributions from NuStar Energy on its common units would have the effect of disproportionately reducing the amount of all distributions that we receive from NuStar Energy based on our ownership interest in the incentive distribution rights in NuStar Energy as compared to cash distributions we receive from NuStar Energy on our general partner interest in NuStar Energy and our NuStar Energy common units.

If NuStar Energy’s general partner is not fully reimbursed or indemnified for obligations and liabilities it incurs in managing the business and affairs of NuStar Energy, it may not be able to satisfy its obligations and its cash flows will be reduced.
The general partner of NuStar Energy and its affiliates may make expenditures on behalf of NuStar Energy for which they will seek reimbursement from NuStar Energy. In addition, under Delaware law, the general partner, in its capacity as the general partner of NuStar Energy, has unlimited liability for the obligations of NuStar Energy, such as its debts and environmental liabilities, except for those contractual obligations of NuStar Energy that are expressly made without recourse to the general partner. To the extent Riverwalk Logistics, L.P. incurs obligations on behalf of NuStar Energy, it is entitled to be reimbursed or indemnified by NuStar Energy. If NuStar Energy does not reimburse or indemnify its general partner, Riverwalk Logistics, L.P. may be unable to satisfy these liabilities or obligations, which would reduce its cash flows. In turn, Riverwalk Logistics, L.P. would have less cash to distribute to us.

If distributions on our units are not paid with respect to any fiscal quarter, our unitholders will not be entitled to receive such payments in the future.
Our distributions to our unitholders are not cumulative. Consequently, if distributions on our units are not paid with respect to any fiscal quarter at the current distribution rate, our unitholders will not be entitled to receive such payments in the future.

Our cash distribution policy limits our growth because we do not retain earnings to reinvest in any acquisitions or growth capital expenditures, and NuStar Energy’s distribution policy may limit NuStar Energy’s growth.
Because we distribute all of our available cash, our growth may not be as fast as businesses that reinvest their available cash to expand ongoing operations. In fact, our growth currently is completely dependent upon NuStar Energy’s ability to increase its quarterly distributions because our only cash-generating assets are indirect ownership interests in NuStar Energy. If we issue additional units or incur debt to fund acquisitions and growth capital expenditures, the payment of distributions on those additional units or interest on that debt could increase the risk that we will be unable to maintain or increase our current per unit distribution level.

Consistent with the terms of its partnership agreement, NuStar Energy distributes to its common unitholders and its general partner its available cash each quarter. In determining the amount of cash available for distribution, NuStar Energy sets aside cash reserves, which it uses to fund its growth capital expenditures. Additionally, it historically has relied upon external financing sources, including commercial borrowings and other debt and equity issuances, to fund its acquisition capital expenditures. Accordingly, to the extent NuStar Energy does not have sufficient cash reserves or is unable to finance growth externally, its cash distribution policy will significantly impair its ability to grow. In addition, to the extent NuStar Energy issues additional units in connection with any acquisitions or growth capital expenditures, the payment of distributions on those

11

Table of Contents

additional units may increase the risk that NuStar Energy will be unable to maintain or increase its per unit distribution level, which in turn may impact the available cash that we have to distribute to our unitholders. The incurrence of additional debt to finance its growth strategy would result in increased interest expense to NuStar Energy, which in turn may impact the available cash that we have to distribute to our unitholders.

If in the future we cease to manage NuStar Energy, we may be deemed to be an investment company under the Investment Company Act of 1940, which would cause us either to have to register as an investment company, obtain exemptive relief from the SEC or modify our organizational structure or our contract rights.
If we cease to manage NuStar Energy as a consequence of Riverwalk Logistics, L.P.’s removal or withdrawal as NuStar Energy’s general partner or otherwise, and are deemed to be an investment company under the Investment Company Act of 1940 because of our ownership of NuStar Energy partnership interests, we would either have to register as an investment company under the Investment Company Act, obtain exemptive relief from the SEC or modify our organizational structure or our contract rights to fall outside the definition of an investment company. Registering as an investment company could, among other things, materially limit our ability to engage in transactions with affiliates, including the sale and purchase of certain securities or other property to or from our affiliates and restrict our ability to borrow funds or engage in other transactions involving leverage.

An increase in interest rates may cause the market price of our units to decline.
As interest rates rise, the ability of investors to obtain higher risk-adjusted rates of return by purchasing government-backed debt securities may cause a corresponding decline in demand for riskier investments generally, including yield-based equity investments, such as limited liability company membership interests. Reduced demand for our units resulting from investors seeking other more favorable investment opportunities may cause the market price of our units to decline.

We may issue an unlimited number of additional securities without the consent of our unitholders, which will dilute each unitholder’s ownership interest in us and may increase the risk that we will be unable to maintain or increase our per unit distribution level.
At any time we may issue an unlimited number of additional securities without the approval of our unitholders on terms and conditions determined by our board of directors. The issuance by us of additional units or other equity securities of equal or senior rank will have the following effects:
our unitholders’ proportionate ownership interest in us will decrease;
the amount of cash available for distribution on each unit may decrease;
the relative voting strength of each previously outstanding unit may be diminished;
the ratio of taxable income to distributions may increase; and
the market price of the units may decline.

NuStar Energy may issue additional NuStar Energy units, which may increase the risk that NuStar Energy will not have sufficient available cash to maintain or increase its per unit cash distribution level and that we will have to make a capital contribution to NuStar Energy.
NuStar Energy may issue additional NuStar Energy units, including units that rank senior to the NuStar Energy common units, preferred units and incentive distribution rights as to quarterly cash distributions, on the terms and conditions established by its general partner. Additionally, we are required to make additional capital contributions to NuStar Energy upon certain issuances by NuStar Energy of additional units in order to maintain our general partner interest in NuStar Energy. Furthermore, to the extent NuStar Energy issues units that are senior to the NuStar Energy common units and the incentive distribution rights, such as the preferred units, their issuance will render more uncertain the payment of distributions on the common units and the incentive distribution rights. Neither the common units nor the incentive distribution rights are entitled to any arrearages from prior quarters; however, the NuStar Energy preferred units are cumulative and must be paid in full before distributions on the NuStar Energy common units and incentive distribution rights can be paid. The payment of distributions on any additional NuStar Energy units may increase the risk that NuStar Energy will be unable to maintain or increase its per unit cash distribution level and the requirement that we make capital contributions to NuStar Energy to maintain our general partner interest may impact the available cash that we have to distribute to our unitholders.

Anti-takeover provisions in our limited liability company agreement may make an acquisition of us complicated and the removal and replacement of our directors and executive officers difficult.
Our limited liability company agreement contains the following provisions that may delay or prevent a change in control. These provisions may also make it difficult for unitholders to remove and replace our board of directors and executive officers.

Section 203. Our limited liability company agreement effectively adopts Section 203 of the Delaware General Corporation Law (DGCL). Section 203 of the DGCL, as it applies to us, prevents an interested unitholder, defined as a person who owns 15% or more of our outstanding units, from engaging in business combinations with us for three years following the time such person

12

Table of Contents

becomes an interested unitholder. Section 203 broadly defines “business combination” to encompass a wide variety of transactions with or caused by an interested unitholder, including mergers, asset sales and other transactions in which the interested unitholder receives a benefit on other than a pro rata basis with other unitholders. This provision of our limited liability company agreement could have an anti-takeover effect with respect to transactions not approved in advance by our board of directors, including discouraging takeover attempts that might result in a premium over the market price for our units.

Limited Voting Rights. Our limited liability company agreement provides that if any person or group other than our affiliates acquires beneficial ownership of 20% or more of any class of units, that person or group loses voting rights on all of its units. This loss of voting rights does not apply to any person or group that acquires all of its units from our affiliates or any transferees of that person or group approved by our board of directors or to any person or group who acquires the units with the prior approval of our board of directors.

Staggered Board. Pursuant to our limited liability company agreement, our board is divided into three classes serving staggered three-year terms. This, when coupled with the provision of our limited liability company agreement authorizing only the board of directors to fill vacant or newly created directorships or increase the size of the board of directors and the provision providing that directors may only be removed at a meeting of unitholders and cannot be removed by written consent, may deter a unitholder from gaining control of our board of directors by removing incumbent directors or increasing the number of directorships and simultaneously filling the vacancies or newly created directorships with its own nominees.

These provisions may delay or prevent a third party from acquiring us and any such delay or prevention could cause the market price of our units to decline.

Unitholders may have liability to repay distributions.
Under certain circumstances, our unitholders may have to repay amounts wrongfully returned or distributed to them. Under Section 18-607 of the Delaware Limited Liability Company Act (the Delaware Act), we may not make a distribution to our unitholders if the distribution would cause our liabilities to exceed the fair value of our assets. Liabilities to members on account of their membership interests and liabilities that are nonrecourse to the limited liability company are not counted for purposes of determining whether a distribution is permitted.

Delaware law provides that, for a period of three years from the date of an impermissible distribution, members who received the distribution and who knew at the time of the distribution that it violated Delaware law will be liable to us for the repayment of the distribution amount. Likewise, upon the winding up of our limited liability company, in the event that (a) we do not distribute assets in the following order: (1) to creditors in satisfaction of their liabilities; (2) to members and former members in satisfaction of liabilities for distributions owed under our limited liability company agreement; (3) to members for the return of their contributions; and finally (4) to the members in the proportions in which the members share in distributions and (b) a member knows at the time that the distribution violated the Delaware Act, then such member will be liable to repay the distribution for a period of three years (subject to certain exceptions) from the impermissible distribution under Section 18-804 of the Delaware Act.

A purchaser of common units will be liable for the obligations of the transferor to make contributions to us that are known to such purchaser at the time it became a member and for unknown obligations, if the liabilities could be determined from our limited liability company agreement.

NuStar Energy’s unitholders may not have limited liability if a court finds that limited partner actions constitute control of NuStar Energy’s business and may, therefore, become liable for certain of NuStar Energy’s obligations, which may have an impact on the cash we have available to make distributions.
Under Delaware law, unitholders could be held liable for NuStar Energy’s obligations to the same extent as a general partner if a court determined that actions of a unitholder constituted participation in the “control” of NuStar Energy’s business.

Under Delaware law, the general partner generally has unlimited liability for the obligations of the partnership, such as its debts and environmental liabilities, except for those contractual obligations of the partnership that are expressly made without recourse to the general partner. In addition, Section 17-607 of the Delaware Revised Uniform Limited Partnership Act provides that, under some circumstances, a limited partner may be liable to NuStar Energy for the amount of a distribution for a period of three years from the date of the distribution.

If we fail to maintain an effective system of internal controls, we may not be able to report our financial results accurately or prevent fraud, which could have a material and adverse impact on our financial condition, results of operations, and cash flows and our ability to make distributions to our unitholders.
We are required to disclose material changes made in our internal controls over financial reporting on a quarterly basis and we are required to assess the effectiveness of our controls annually. Effective internal controls are necessary for us to provide reliable and timely financial reports. We may be unable to maintain effective controls over our financial processes and reporting in the future or to comply with our obligations under Section 404 of the Sarbanes-Oxley Act of 2002. For example, Section 404 requires us, among other things, annually to review and report on the effectiveness of our internal control over financial reporting. Any failure to maintain effective internal controls or to improve our internal controls could harm our operating results or cause us to fail to meet our reporting obligations.

Given the difficulties inherent in the design and operation of internal controls over financial reporting, we can provide no assurance as to our, or our independent registered public accounting firm’s, future conclusions about the effectiveness of our internal controls, and we may incur significant costs in our efforts to comply with Section 404. Any failure to maintain effective internal controls over financial reporting will subject us to regulatory scrutiny and a loss of confidence in our reported financial information, which could have a material adverse effect on our financial condition, results of operations and cash flows and our ability to make distributions to our unitholders.

RISKS RELATED TO CONFLICTS OF INTEREST

Although we manage NuStar Energy through our indirect ownership of its general partner, NuStar Energy’s general partner owes fiduciary duties to NuStar Energy and NuStar Energy’s unitholders, which may conflict with our interests.
Conflicts of interest exist and may arise in the future as a result of the relationships between us and our affiliates, including NuStar Energy’s general partner, on the one hand, and NuStar Energy and its limited partners, on the other hand. The directors and officers of NuStar GP, LLC have fiduciary duties to manage NuStar Energy’s business in a manner beneficial to us, its owner. At the same time, NuStar GP, LLC has a fiduciary duty to manage NuStar Energy in a manner beneficial to NuStar Energy and its unitholders. The board of directors of NuStar GP, LLC or its conflicts committee will resolve any such conflict and have broad latitude to consider the interests of all parties to the conflict. Our independent directors are not the same as the independent directors who serve on the conflicts committee of NuStar GP, LLC. The resolution of these conflicts may not always be in our best interest or that of our unitholders. For example, conflicts of interest may arise in the following situations:
the allocation of shared overhead expenses to NuStar Energy and us;
the determination and timing of the amount of cash to be distributed to NuStar Energy’s partners and the amount of cash to be reserved for the future conduct of NuStar Energy’s business;
any proposal by NuStar GP, LLC to eliminate, reduce or modify the incentive distribution rights;
the decision whether NuStar Energy should make acquisitions, and on what terms;
the determination of whether NuStar Energy should use cash on hand, borrow or issue equity to raise cash to finance acquisitions or expansion capital projects, repay indebtedness, meet working capital needs, pay distributions to NuStar Energy’s partners or otherwise; and
any decision we make in the future to engage in business activities independent of, or in competition with, NuStar Energy.

Our limited liability company agreement limits and modifies our directors’ fiduciary duties and the fiduciary duties of our officers and directors may conflict with those of the general partner of NuStar Energy’s general partner’s officers and directors.
Our limited liability company agreement contains provisions that modify and limit our directors’ fiduciary duties to our unitholders. For example, our limited liability company agreement provides that:
our directors will not have any liability to us or our unitholders for decisions made in good faith, meaning they believed the decision was in our best interests; and
our board of directors will not be liable for monetary damages to us or our unitholders for any acts or omissions unless there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that the board of directors acted in bad faith or engaged in fraud or willful misconduct or, in the case of a criminal matter, acted with knowledge that such conduct was unlawful.

Our directors and officers have fiduciary duties to manage our business in a manner beneficial to us and our unitholders. Simultaneously, two of our directors and all of our officers are also directors and officers of NuStar GP, LLC, the general partner of NuStar Energy’s general partner, and have fiduciary duties to manage the business of NuStar Energy in a manner beneficial to NuStar Energy and its unitholders. For instance, William E. Greehey is our Chairman of the Board as well as the Chairman of the Board of NuStar GP, LLC. Consequently, these directors and officers may encounter situations in which their fiduciary obligations to NuStar Energy, on the one hand, and us, on the other hand, are in conflict. The resolution of these

14

Table of Contents

conflicts may not always be in our best interest or that of our unitholders. Our executive officers, who are also the executive officers of NuStar GP, LLC, will allocate, in their reasonable and sole discretion, their time spent on our behalf and on behalf of NuStar Energy. These allocations may not be the result of arms-length negotiations between NuStar GP, LLC and us and, therefore, the allocations may not exactly match the actual time and overhead spent.

RISKS RELATED TO NUSTAR ENERGY’S BUSINESS

NuStar Energy s future financial and operating flexibility may be adversely affected by its significant leverage, any future downgrades of its credit ratings, restrictions in its debt agreements and conditions in the financial markets.
As of December 31, 2017, NuStar Energy’s consolidated debt was $3.6 billion, and it has the ability to incur more debt. NuStar Energy also may be required to post cash collateral under certain of its hedging arrangements, which it expects to fund with borrowings under its revolving credit agreement. In addition to any potential direct financial impact of NuStar Energy’s debt, it is possible that any material increase to NuStar Energy’s debt or other negative financial factors may be viewed negatively by credit rating agencies, which could result in ratings downgrades and increased costs for NuStar Energy to access the capital markets. In November 2017, S&P Global Ratings downgraded NuStar Energy’s credit rating from BB+ Stable to BB Negative outlook, which raised the interest rate on its 7.65% Senior Notes Due 2018 (the 2018 Senior Notes). In February 2018, Moody’s Investors Service, Inc. downgraded NuStar Energy’s credit rating from Ba1 to Ba2, which increased the interest rate on both the 2018 Senior Notes and amounts borrowed under its credit facilities. Any additional downgrades in NuStar Energy’s credit ratings in the future could result in further increases to the interest rate on its 2018 Senior Notes, significantly increase its capital costs, reduce its liquidity and adversely affect its ability to raise capital in the future.

NuStar Energy’s revolving credit agreement contains restrictive covenants, such as limitations on indebtedness, liens, mergers, asset transfers and certain investing activities. In addition, the revolving credit agreement generally requires NuStar Energy to maintain, as of the end of each rolling period (consisting of any period of four consecutive fiscal quarters) a consolidated debt coverage ratio (consolidated debt to consolidated EBITDA, each as defined in the revolving credit agreement) not to exceed 5.00-to-1.00, except in specific circumstances, including acquisitions by NuStar Energy for aggregate net consideration of at least $50 million, when NuStar Energy is permitted to maintain a consolidated debt coverage ratio of up to 5.50-to-1.00 for two rolling periods, as provided in its revolving credit agreement. NuStar Energy’s maximum permitted ratio was raised to 5.50-to-1.00 through March 31, 2018 due to its acquisition of Navigator Energy Services, LLC. NuStar Energy also amended its revolving credit agreement in November 2017 to exclude NuStar Logistics, L.P.’s 7.625% Fixed-to-Floating Rate Subordinated Notes Due 2043 (the Junior Sub Notes) from its calculation of consolidated debt through December 31, 2018. Failure by NuStar Energy to comply with any of the revolving credit agreement restrictive covenants or its required coverage ratio will result in a default and could result in acceleration of its obligations under the revolving credit agreement and possibly other indebtedness. Future financing agreements NuStar Energy may enter into may contain similar or more restrictive covenants than those it has negotiated for its current financing agreements.

NuStar Energy’s accounts receivable securitization program contains various customary affirmative and negative covenants and default, indemnification and termination provisions. In addition, the related receivables financing agreement pursuant to which NuStar Energy is initial servicer and performance guarantor provides for acceleration of amounts owed upon the occurrence of certain specified events.

NuStar Energy’s debt service obligations, restrictive covenants and maturities resulting from its leverage may adversely affect NuStar Energy’s ability to finance future operations, pursue acquisitions, fund its capital needs and pay cash distributions to its unitholders, including us. In addition, this leverage may make NuStar Energy’s results of operations more susceptible to adverse economic or operating conditions, limit its flexibility in planning for, or reacting to, changes in its business and industry and place it at a competitive disadvantage compared to competitors with proportionately less indebtedness. For example, during an event of default under certain of NuStar Energy’s debt agreements, NuStar Energy would be prohibited from making cash distributions to its unitholders, including us. Also, if any of NuStar Energy’s lenders files for bankruptcy or experiences severe financial hardship, they may not honor their pro rata share of NuStar Energy’s borrowing requests under the revolving credit agreement, which may significantly reduce its available borrowing capacity and, as a result, materially adversely affect NuStar Energy’s financial condition and ability to pay distributions to its unitholders, including us.

NuStar Energy’s ability to service its debt will depend on, among other things, its future financial and operating performance, which will be affected by prevailing economic conditions and financial, business, regulatory and other factors, some of which are beyond its control. If NuStar Energy’s operating results are not sufficient to service its indebtedness, it may be required to reduce its distributions, reduce or delay its business activities, investments or capital expenditures, sell assets or issue equity, which could materially and adversely affect its financial condition, results of operations, cash flows and ability to make distributions to its unitholders, as well as the trading price of its units.

Depending on conditions in the credit and capital markets at a given time, NuStar Energy may not be able to obtain funding on acceptable terms or at all, which may hinder or prevent it from meeting its future capital needs.
From time to time, the domestic and global financial markets and economic conditions are volatile and disrupted by a variety of factors, including low consumer confidence, high unemployment, geoeconomic and geopolitical issues, weak economic conditions and uncertainty in the market. In addition, there are fewer investors and lenders for debt and equity capital market issuances by master limited partnerships, such as NuStar Energy, than there are for corporate issuances. As a result, NuStar Energy’s cost of raising capital in the debt and equity capital markets could increase substantially, possibly at a time when the availability of funds from these markets has diminished. The cost of obtaining funds from the credit markets may increase as interest rates increase and tighter lending standards are enacted, and lenders may refuse to refinance existing debt on similar terms or at all and reduce, or in some cases cease to provide, funding to borrowers.

In addition, lending counterparties under NuStar Energy’s existing revolving credit facility and other debt instruments may be unwilling or unable to meet their funding obligations. Due to these factors, NuStar Energy cannot be certain that new financing or funding will be available on acceptable terms. If funding is not available when needed, or is available only on unfavorable terms, NuStar Energy may be unable to execute its growth strategy, complete future acquisitions or construction projects or take advantage of other business opportunities, any of which could have a material adverse effect on its revenues and results of operations.

A significant portion of NuStar Energy’s debt matures over the next five years and will need to be repaid or refinanced, and changes to the debt and equity markets could limit its refinancing options.
A significant portion of NuStar Energy’s debt is set to mature within the next five years, including its revolving credit facility. NuStar Energy may not be able to refinance its maturing debt on commercially reasonable terms, or at all, depending on numerous factors, including its financial condition and prospects at the time and the then-current state of the banking and capital markets in the United States.

Increases in interest rates could adversely affect NuStar Energy’s business and the trading price of NuStar Energy’s units.
NuStar Energy has significant exposure to increases in interest rates through variable rate provisions in certain of its debt instruments. As of December 31, 2017, NuStar Energy had approximately $3.6 billion of consolidated debt, of which $2.3 billion was at fixed interest rates and $1.3 billion was at variable interest rates. Also, in January 2018 the interest rates on NuStar Energy’s Junior Sub Notes shifted from a fixed rate to a floating annual rate equal to the sum of the three-month LIBOR rate for the related quarterly interest period, plus 6.734%. Additionally, at December 31, 2017, NuStar Energy had $600.0 million aggregate notional amount of interest rate swap arrangements, which may expose it to risk of financial loss. Prior ratings downgrades on NuStar Energy’s existing indebtedness caused interest rates under its revolving credit agreement and its 2018 Senior Notes to increase, and any future downgrades may further increase the interest rate on its 2018 Senior Notes. NuStar Energy’s results of operations, cash flows and financial position could be materially adversely affected by significant changes in interest rates. In addition, NuStar Energy historically has funded its strategic capital expenditures and acquisitions from external sources, primarily borrowings under its revolving credit agreement or funds raised through debt or equity offerings. An increase in interest rates may also have a negative impact on NuStar Energy’s ability to access the capital markets at economically attractive rates.

Furthermore, the market price of master limited partnership units such as NuStar Energy’s, like other yield-oriented securities, may be affected by, among other factors, implied distribution yield. The distribution yield is often used by investors to compare and rank yield-oriented securities for investment decision-making purposes. Therefore, increases or decreases in interest rates may affect whether or not certain investors decide to invest in master limited partnership units, including NuStar Energy’s, and a rising interest rate environment could have an adverse impact on its unit price and impair its ability to issue additional equity or incur debt to fund growth or for other purposes, including distributions.
 
Continued low crude oil prices could have an adverse impact on NuStar Energy’s results of operations, cash flows and ability to make distributions to its unitholders, including us.
Since late 2014, the price of crude oil has been depressed, which has caused most crude oil producers to reduce their capital spending and drilling activity and narrow their focus to assets in the most cost-advantaged regions. On the other hand, refiners have benefited from lower crude prices, to the extent that lower feedstock price has been coupled with higher demand for certain refined products in some regional markets. While only a portion of NuStar Energy’s total business is directly affected by the price of crude, continued low crude oil prices and related overall economic downturn could have a negative impact on its cash flows and results of operations.

Table of Contents

An extended period of reduced demand for or supply of crude oil and refined products could affect NuStar Energy’s results of operations and ability to make distributions to its unitholders, including us.
Although NuStar Energy enters into throughput and deficiency agreements to protect against near-term fluctuations whenever possible, its business is ultimately dependent upon the long-term demand for and supply of the crude oil and refined products it transports in its pipelines and stores in its terminals. Any sustained decrease in demand for refined products in the markets NuStar Energy’s pipelines and terminals serve that extends beyond the expiration of its existing throughput and deficiency agreements could result in a significant reduction in throughputs in its pipelines and storage in its terminals, which would reduce its cash flows and impair its ability to make distributions to its unitholders, including us. Factors that tend to decrease market demand include:
a recession or other adverse economic condition that results in lower spending by consumers on gasoline, diesel and travel;
higher fuel taxes or other governmental or regulatory actions that increase, directly or indirectly, the cost of gasoline;
an increase in automotive engine fuel economy, whether as a result of a shift by consumers to more fuel-efficient vehicles or technological advances by manufacturers;
new regulations or court decisions requiring the phase out or reduced use of gasoline-fueled vehicles;
the increased use of alternative fuel sources;
an increase in the market price of crude oil that leads to higher refined product prices, which may reduce demand for refined products and drive demand for alternative products. Market prices for crude oil and refined products, including fuel oil, are subject to wide fluctuation in response to changes in global and regional supply that are beyond NuStar Energy’s control, and increases in the price of crude oil may result in a lower demand for refined products that NuStar Energy transports, stores and markets, including fuel oil; and
a decrease in corn acres planted for ethanol, which may reduce demand for anhydrous ammonia.

Similarly, any sustained decrease in the supply of crude oil and refined products in markets NuStar Energy serves could result in a significant reduction in throughputs in its pipelines and storage in its terminals, which would reduce its cash flows and undermine its ability to make distributions to its unitholders, including us. Factors that tend to decrease supply and, by extension, utilization of NuStar Energy’s pipelines and terminals include:
prolonged periods of low prices for crude oil and refined products, which could lead to a decrease in exploration and development activity and reduced production in markets served by NuStar Energy’s pipelines and storage terminals;
a lack of drilling services or equipment available to accommodate production needs;
changes in laws, regulations, sanctions or taxation that directly or indirectly delay supply or production or increase the cost of production of refined products; and
macroeconomic forces affecting, or actions taken by, foreign oil and gas producing nations that impact supply of and prices for crude oil and refined products.

NuStar Energy’s inability to develop and execute growth projects and acquire new assets could limit its ability to maintain and grow quarterly distributions to its unitholders, including us.
NuStar Energy’s ability to maintain and grow its distributions to unitholders, including us, depends on the growth of NuStar Energy’s existing businesses and strategic acquisitions. Decisions regarding new growth projects rely on numerous estimates, including, among other factors, predictions of future demand for NuStar Energy’s services, future supply shifts, crude oil production estimates, commodity price environments, economic conditions, both domestic and foreign, and potential changes in the financial condition of NuStar Energy’s customers. NuStar Energy’s predictions of such factors could cause it to forego certain investments and to lose opportunities to competitors who make investments based on different predictions. If NuStar Energy is unable to acquire new assets, due either to high prices or a lack of attractive synergistic targets, its future growth will be limited. In addition, NuStar Energy’s future growth will be limited if it is unable to develop additional expansion projects, implement business development opportunities and finance such activities on economically acceptable terms, which could adversely impact its results of operations and cash flows and, accordingly, result in reduced distributions to unitholders, including us, over time.

Failure to complete capital projects as planned could adversely affect NuStar Energy’s financial condition, results of operations and cash flows.
Delays or cost increases related to capital spending programs involving construction of new facilities (or improvements and repairs to NuStar Energy’s existing facilities) could adversely affect NuStar Energy’s ability to achieve forecasted operating results. Although NuStar Energy evaluates and monitors each capital spending project and tries to anticipate difficulties that may arise, such delays or cost increases may arise as a result of factors that are beyond its control, including:
non-performance or delay by, or disputes with, counterparties, vendors, suppliers, contractors or subcontractors involved with a project;

17

Table of Contents

denial or delay in issuing requisite regulatory approvals and/or permits;
protests and other activist interference with planned or in-process projects;
unplanned increases in the cost of construction materials or labor;
disruptions in transportation of modular components and/or construction materials;
severe adverse weather conditions, natural disasters or other events (such as equipment malfunctions, explosions, fires or spills) affecting NuStar Energy’s facilities, or those of vendors and suppliers;
shortages of sufficiently skilled labor, or labor disagreements resulting in unplanned work stoppages; or
market-related increases in a project’s debt or equity financing costs.

NuStar Energy will incur financing costs during the planning and construction phases of its projects; however, the operating cash flows it expects these projects to generate will not materialize until sometime after the projects are completed, if at all. Additionally, NuStar Energy’s forecasted operating results from capital spending projects are based upon its projections of future market fundamentals that are not within its control, including changes in general economic conditions, the supply and demand of crude oil and refined products, availability to its customers of attractively priced alternative solutions for storage, transportation or supplies of crude oil and refined products and overall customer demand.

If NuStar Energy is unable to retain or replace current customers and existing contracts to maintain utilization of its pipeline and storage assets at current or more favorable rates, NuStar Energy’s revenue and cash flows could be reduced to levels that could adversely affect its ability to make quarterly distributions to its unitholders, including us.
NuStar Energy’s revenue and cash flows are generated primarily from its customers’ payments of fees under throughput contracts and storage agreements. Failure by NuStar Energy to renew or enter into new contracts or its storage customers’ material reduction of their utilization under existing contracts could result from many factors, including:
continued low crude oil prices;
a material decrease in the supply or price of crude oil;
a material decrease in demand for refined products in the markets served by NuStar Energy’s pipelines and terminals;
political, social or economic instability in another country impacting a customer based there;
competition for customers from companies with comparable assets and capabilities;
scheduled turnarounds or unscheduled maintenance at refineries NuStar Energy serves;
operational problems or catastrophic events affecting NuStar Energy’s assets or a refinery it serves;
environmental proceedings or other litigation that compel the cessation of all or a portion of the operations at NuStar Energy’s assets or a refinery it serves;
increasingly stringent environmental, health, safety and security regulations;
a decision by NuStar Energy’s current customers to redirect refined products transported in NuStar Energy’s pipelines to markets not served by NuStar Energy’s pipelines or to transport crude oil or refined products by means other than NuStar Energy’s pipelines; or
a decision by NuStar Energy’s current customers to sell one or more of the refineries NuStar Energy serves to a purchaser that elects not to use NuStar Energy’s pipelines and terminals.

Competing midstream service providers, including certain major energy and chemical companies, possess, or have greater financial resources to acquire, assets better suited to meet customer demand, which could undermine NuStar Energy’s ability to obtain and retain customers or reduce utilization of its assets, which could reduce NuStar Energy’s revenues and cash flows, thereby reducing its ability to make its quarterly distributions to unitholders, including us.
NuStar Energy’s competitors include major energy and chemical companies, some of which have greater financial resources, more pipelines or storage terminals, greater capacity pipelines or storage terminals and greater access to supply than NuStar Energy does. Certain of its competitors also may have advantages in competing for acquisitions or other new business opportunities because of their financial resources and synergies in operations. As a consequence of increased competition in the industry, some of NuStar Energy’s customers may be reluctant to renew or enter into long-term contracts or contracts that provide for minimum throughput amounts in the future. NuStar Energy’s inability to renew or replace current contracts as they expire, to enter into contracts for newly acquired, constructed or expanded assets and to respond appropriately to changing market conditions could have a negative effect on NuStar Energy’s revenue, cash flows and ability to make quarterly distributions to its unitholders, including us.

NuStar Energy’s operations are subject to operational hazards and interruptions, and NuStar Energy cannot insure against and/or predict all potential losses and liabilities that might result therefrom.
NuStar Energy’s operations and those of its customers and suppliers are subject to operational hazards and unforeseen interruptions such as natural disasters, adverse weather conditions (such as hurricanes, tornadoes, storms and floods), accidents, fires, explosions, hazardous materials releases, mechanical failures and other events beyond its control. In addition, many scientists hypothesize that global climatic changes are occurring that are likely to cause an increase in hurricanes and other

18

Table of Contents

severe weather conditions. These events might result in a loss of life or equipment, injury or extensive property damage, as well as an interruption in NuStar Energy’s operations or those of its customers or suppliers. In the event any of NuStar Energy’s facilities, or those of its customers or suppliers, suffer significant damage or are forced to shut down for a significant period of time, it may have a material adverse effect on NuStar Energy’s earnings, its other results of operations and its financial condition as a whole.

As a result of market conditions, premiums and deductibles for certain of NuStar Energy’s insurance policies have increased substantially and could escalate further; therefore, NuStar Energy may not be able to maintain or obtain insurance of the type and amount it desires at reasonable rates. Certain insurance coverage could become subject to broad exclusions, become unavailable altogether or become available only for reduced amounts of coverage and at higher rates. For example, NuStar Energy’s insurance carriers require broad exclusions for losses due to terrorist acts. If NuStar Energy were to incur a significant liability for which it is not fully insured, such a liability could have a material adverse effect on NuStar Energy’s financial position and its ability to make distributions to its unitholders, including us, and to meet its debt service requirements.

NuStar Energy could be subject to damages or lose customers due to failure to maintain certain quality specifications or other claims related to the operation of its assets and the services it provides to its customers.
Certain of the products NuStar Energy stores and transports are produced to precise customer specifications. If NuStar Energy fails to maintain the quality and purity of the products it receives and/or a product fails to perform in a manner consistent with the quality specifications required by the customer, the customer could seek replacement of the product or damages for costs incurred as a result of the product failing to perform as guaranteed. NuStar Energy also could face other claims by its customers if its assets do not operate as expected by its customers or its services otherwise do not meet its customers’ expectations. A successful claim or series of claims against NuStar Energy could result in unforeseen expenditures and a loss of one or more customers.

NuStar Energy is exposed to counterparty credit risk. Nonpayment and nonperformance by NuStar Energy’s customers, vendors or derivative counterparties could reduce its revenues, increase its expenses and otherwise have a negative impact on its ability to conduct its business, operating results, cash flows and ability to make distributions to its unitholders, including us.
Weak economic conditions and widespread financial stress could reduce the liquidity of NuStar Energy’s customers, vendors or counterparties, making it more difficult for them to meet their obligations to NuStar Energy. NuStar Energy is therefore subject to risks of loss resulting from nonpayment or nonperformance by its customers to whom it extends credit. Severe financial problems encountered by NuStar Energy’s customers could limit its ability to collect amounts owed to it, or to enforce the performance of obligations owed to it under contractual arrangements. For example, a substantial portion of NuStar Energy’s St. Eustatius facility revenue derives from its storage of petroleum products exported from Venezuela on behalf of Petróleos de Venezuela, S.A. (PDVSA), a state-owned Venezuelan oil company. Significant political, social and economic instability in Venezuela, including constraints on foreign currency transactions by the Venezuelan government, has caused PDVSA to utilize NuStar Energy’s assets significantly less than it forecasted and late-pay invoices from time to time. NuStar Energy’s involvement with products exported from Venezuela also exposes it to the risk of trade restrictions and economic embargoes imposed by the United States and other countries.

In addition, nonperformance by vendors who have committed to provide NuStar Energy with critical products or services could raise its costs or interfere with its ability to successfully conduct its business. Furthermore, nonpayment by the counterparties to any of NuStar Energy’s outstanding derivatives could expose it to additional interest rate or commodity price risk. While NuStar Energy attempts to mitigate its risk through warehouseman’s liens and other security protections, any substantial increase in the nonpayment and nonperformance by its customers, vendors or counterparties could have a material adverse effect on its results of operations, cash flows and ability to make distributions to unitholders, including us.

Cybersecurity breaches and other disruptions could compromise NuStar Energy’s information and operations, and expose it to liability, which would cause its business and reputation to suffer.
NuStar Energy relies on its information technology infrastructure to process, transmit and store electronic information, including information it uses to safely operate its assets. In recent years, there has been a rise in the number of cyberattacks on other companies’ network and information systems by both state-sponsored and criminal organizations, and as a result, the risks associated with such an event continue to increase. A significant failure, compromise, breach or interruption in NuStar Energy’s systems could result in a disruption of its operations, customer dissatisfaction, damage to its reputation, a loss of customers or revenues and potential regulatory fines. If any such failure, interruption or similar event results in improper disclosure of information maintained in NuStar Energy’s information systems and networks or those of its vendors, including personnel, customer and vendor information, it could also be subject to liability under relevant contractual obligations and laws and regulations protecting personal data and privacy. NuStar Energy’s financial results could also be adversely affected if

19

Table of Contents

operational systems are breached or an employee causes its operational systems to fail, either as a result of inadvertent error or by deliberately tampering with or manipulating its operational systems.

Although NuStar Energy believes that it has robust information security procedures and other safeguards in place, as cyberthreats continue to evolve, it may be required to expend additional resources to continue to enhance its information security measures and/or to investigate and remediate information security vulnerabilities.

Acquisitions and expansions, if any, may increase substantially the level of NuStar Energy’s indebtedness and contingent liabilities or otherwise change its capital structure, and NuStar Energy may be unable to integrate acquisitions and expansions effectively into its existing operations.
From time to time, NuStar Energy evaluates and acquires assets and businesses that it believes complement or diversify its existing assets and operations. Acquisitions may require NuStar Energy to raise a substantial amount of equity or incur a substantial amount of indebtedness. If NuStar Energy consummates any future material acquisitions, its capitalization and results of operations may change significantly, and unitholders will not have the opportunity to evaluate the economic, financial and other relevant information that NuStar Energy will consider in connection with any future acquisitions.

Part of NuStar Energy’s overall business strategy includes acquiring additional assets that complement NuStar Energy’s existing asset base and distribution capabilities or provide entry into new markets. NuStar Energy may not be able to identify suitable acquisitions, or it may not be able to purchase or finance any acquisitions on terms that it finds acceptable. Additionally, NuStar Energy competes against other companies for acquisitions, and NuStar Energy may not be successful in the acquisition of any assets or businesses appropriate for its growth strategy.

Even if NuStar Energy does consummate acquisitions that it believes will increase distributable cash flow, these acquisitions may nevertheless result in a decrease in distributable cash flow. Any acquisition involves potential risks, including, among other things:
NuStar Energy may not be able to obtain the cost savings and financial improvements it anticipates or acquired assets may not perform as NuStar Energy expects;
NuStar Energy may not be able to successfully integrate the assets, management teams or employees of the businesses it acquires with its assets and management team, or such integration may be significantly delayed;
NuStar Energy may fail or be unable to discover some of the liabilities of businesses that it acquires, including liabilities resulting from a prior owner’s noncompliance with applicable federal, state or local laws;
NuStar Energy may have assumed prior known or unknown liabilities for which it may not be indemnified or have adequate insurance;
acquisitions may divert the attention of NuStar Energy’s senior management from focusing on its core business;
NuStar Energy may experience a decrease in its liquidity by using a significant portion of its available cash or borrowing capacity to finance acquisitions; and
NuStar Energy may face the risk that its existing financial controls, information systems, management resources and human resources will need to grow to support future growth.

NuStar Energy operates a global business that exposes it to additional risk.
NuStar Energy operates a global business. A significant portion of its revenues come from its business outside of the United States, and its operations are subject to various risks unique to each country that could have a material adverse effect on its business, results of operations and financial condition. With respect to any particular country, these risks may include political and economic instability, including: civil unrest, war and other armed conflict; inflation; and currency fluctuations, devaluation and conversion restrictions. NuStar Energy is also exposed to the risk of governmental actions that may: limit or disrupt markets for its operations, restrict payments to it or limit the movement of funds; impose sanctions on its ability to conduct business with certain customers or persons; or result in the deprivation of contract rights. Its operations outside the United States may also be affected by changes in trade protection laws, policies and measures, and other regulatory requirements affecting trade and investment, including the Foreign Corrupt Practices Act, the United Kingdom Bribery Act and other foreign laws prohibiting corrupt payments, as well as import and export regulations. Additionally, negotiations are ongoing regarding the United Kingdom’s exit from the European Union, and any future effects from this are currently unknown.

NuStar Energy also has assets in, or does business with customers based in, certain emerging markets, and the developing nature of these markets presents a number of risks. In addition, due to the unsettled political conditions in many oil-producing countries, NuStar Energy’s operations may be subject to the adverse consequences of war, civil unrest, strikes, currency controls and governmental actions. Deterioration of social, political, labor or economic conditions, including the increasing threat of terrorist organizations and drug cartels, in a country or region in which NuStar Energy does business, or affecting a customer with whom NuStar Energy does business, as well as difficulties in staffing and managing foreign operations, may adversely affect its operations or financial results. For example, PDVSA, a state-owned oil company in Venezuela, is a

20

Table of Contents

significant customer at NuStar Energy’s terminal facility in St. Eustatius, and recent political, social and economic instability in Venezuela seems to have had a negative impact on both PDVSA’s utilization of NuStar Energy’s facility and its ability to timely pay amounts invoiced.

NuStar Energy is subject to laws and sanctions implemented by the United States and foreign jurisdictions where it does business that may restrict the type of business it is permitted to conduct with certain entities, including PDVSA, restrict its activities in certain countries, or even restrict the services it may provide with respect to crude oil or other products produced in certain countries.   In 2017, the United States and the European Union imposed sanctions relating to Venezuela and PDVSA.  While these sanctions do not prohibit NuStar Energy from continuing to perform under its existing contracts with PDVSA, the sanctions may increase the likelihood that PDVSA will be unable to perform its obligations to NuStar Energy.  In addition, in the event additional sanctions are imposed in the future relating to Venezuela or PDVSA, such future sanctions may result in further deterioration of PDVSA’s ability to perform its obligations to NuStar Energy and could prevent it from continuing to serve PDVSA in St. Eustatius.

NuStar Energy does not own all of the land on which its pipelines and facilities have been constructed, and NuStar Energy is therefore subject to the possibility of increased costs or the inability to retain necessary land use.
NuStar Energy obtains the rights to construct and operate its pipelines, storage terminals and other facilities on land owned by third parties and governmental agencies. Many of these rights-of-way or other property rights are perpetual in duration, but others are for a specific period of time. In addition, some of NuStar Energy’s facilities are located on leased premises. Its loss of property rights, through its inability to renew right-of-way contracts or leases or otherwise, could adversely affect its operations and cash flows available for distribution to unitholders, including us.

In addition, the construction of additions to NuStar Energy’s existing assets may require it to obtain new rights-of-way or property rights prior to construction. NuStar Energy may be unable to obtain such rights-of-way or other property rights to connect new supplies to its existing pipelines, storage terminals or other facilities or to capitalize on other attractive expansion opportunities. Additionally, it may become more expensive for NuStar Energy to obtain new rights-of-way or other property rights or to renew existing rights-of-way or property rights. If the cost of obtaining new or renewing existing rights-of-way or other property rights increases, it may adversely affect NuStar Energy’s operations and cash flows available for distribution to unitholders, including us.

NuStar Energy may be unable to obtain or renew permits necessary for its operations, which could inhibit its ability to do business.
NuStar Energy’s facilities operate under a number of federal, state and local permits, licenses and approvals with terms and conditions containing a significant number of prescriptive limits and performance standards in order to operate. These limits and standards require a significant amount of monitoring, recordkeeping and reporting in order to demonstrate compliance with the underlying permit, license or approval. Noncompliance or incomplete documentation of NuStar Energy’s compliance status may result in the imposition of fines, penalties and injunctive relief. In addition, public protest and responsive government intervention have recently made it more difficult for some energy companies to acquire the permits required to complete planned infrastructure projects. A decision by a government agency to deny or delay issuing a new or renewed permit, license or approval, or to revoke or substantially modify an existing permit, license or approval, could have a material adverse effect on NuStar Energy’s ability to continue operations and on its financial condition, results of operations, cash flows and ability to make distributions to its unitholders, including us.

NuStar Energy may have liabilities from its assets that preexist NuStar Energy’s acquisition of those assets, but that may not be covered by indemnification rights NuStar Energy may have against the sellers of the assets.
In some cases, NuStar Energy may have indemnified the previous owners and operators of acquired assets. Some of NuStar Energy’s assets have been used for many years to transport and store crude oil and refined products, and releases may have occurred in the past that could require costly future remediation. If a significant release or event occurred in the past, the liability for which was not retained by the seller, or for which indemnification from the seller is not available, it could adversely affect NuStar Energy’s financial position and results of operations. Conversely, if future releases or other liabilities arise from assets NuStar Energy has sold, NuStar Energy could incur costs related to those liabilities if the buyer possesses valid indemnification rights against it with respect to those assets.

Climate change legislation and other regulatory initiatives may decrease demand for the products NuStar Energy stores, transports and sells and increase NuStar Energy’s operating costs.
In response to scientific studies asserting that emissions of certain “greenhouse gases” such as carbon dioxide and methane may be contributing to warming of the Earth’s atmosphere, the U.S. Congress, European Union and other political bodies have considered legislation or regulation to reduce emissions of greenhouse gases. Passage of climate change or fuels legislation or other regulatory initiatives in fuel efficiency, fuel additives, renewable fuels and other areas in which NuStar Energy conducts

21

Table of Contents

business, could result in changes to the demand for the products NuStar Energy stores, transports and sells, and could increase the costs of NuStar Energy’s operations, including costs to operate and maintain its facilities, install new emission controls on its facilities, acquire allowances to authorize its greenhouse gas or other emissions, pay any taxes related to its greenhouse gas or other emissions or administer and manage emissions programs. In addition, certain of NuStar Energy’s blending operations can result in requirements to purchase renewable energy credits. Even though NuStar Energy attempts to mitigate such lost revenues or increased costs through the contracts it signs with its customers, NuStar Energy may be unable to recover those revenues or mitigate the increased costs, and any such recovery may depend on events beyond its control, including the outcome of future rate proceedings before the Federal Energy Regulatory Commission (the FERC), the Surface Transportation Board (STB) or other regulators and the provisions of any final legislation or regulations. Reductions in NuStar Energy’s revenues or increases in its expenses as a result of climate change legislation or other regulatory initiatives could have adverse effects on NuStar Energy’s business, financial position, results of operations and prospects.

NuStar Energy’s operations are subject to federal, state and local laws and regulations, in the U.S. and in the other countries in which it operates, relating to environmental, health, safety and security that could require NuStar Energy to make substantial expenditures.
NuStar Energy’s operations are subject to increasingly stringent federal, state and local environmental, health, safety and security laws and regulations. Transporting, storing and distributing hazardous materials, including petroleum products, entails the risk that these products may be released into the environment, potentially causing substantial expenditures for a response action, significant government penalties, liability to government agencies including for damages to natural resources, personal injury or property damages to private parties and significant business interruption. Further, certain of NuStar Energy’s pipeline facilities may be subject to the pipeline integrity and safety regulations of various federal and state regulatory agencies. In recent years, increased regulatory focus on pipeline integrity and safety has resulted in various proposed or adopted regulations. The implementation of these regulations, and the adoption of future regulations, could require NuStar Energy to make additional capital expenditures, including to install new or modified safety measures, or to conduct new or more extensive maintenance programs.

Current and future legislative action and regulatory initiatives could also result in changes to operating permits, material changes in operations, increased capital expenditures and operating costs, increased costs of the goods NuStar Energy transports and decreased demand for products it handles that cannot be assessed with certainty at this time. NuStar Energy may be required to make expenditures to modify operations or install pollution control equipment or release prevention and containment systems that could materially and adversely affect its business, financial condition, results of operations and liquidity if these expenditures, as with all costs, are not ultimately reflected in the tariffs and other fees it receives for its services.

NuStar Energy owns or leases a number of properties that were used to transport, store or distribute products for many years before NuStar Energy acquired them; therefore, such properties were operated by third parties whose handling, disposal or release of products and wastes was not under NuStar Energy’s control. Environmental laws and regulations could impose obligations to conduct assessment or remediation efforts at NuStar Energy’s facilities, third-party sites where it takes wastes for disposal, or where wastes have migrated. Environmental laws and regulations also may impose joint and several liabilities on NuStar Energy for the conduct of third parties or for actions that complied with applicable requirements when taken, regardless of negligence or fault.

If NuStar Energy were to incur a significant liability pursuant to environmental, health, safety or security laws or regulations, such a liability could have a material adverse effect on its financial position and its ability to make distributions to its unitholders, including us, and its ability to meet its debt service requirements.

NuStar Energy’s interstate common carrier pipelines are subject to regulation by the FERC.
The FERC regulates the tariff rates and terms and conditions of service for interstate oil movements on NuStar Energy’s common carrier pipelines. FERC regulations require that these rates must be just and reasonable and that the pipeline not engage in undue discrimination or undue preference with respect to any shipper. Under the Interstate Commerce Act, the FERC or shippers may challenge NuStar Energy’s pipeline tariff filings, including rates and terms and conditions of service. Further, other than for rates set under market-based rate authority, if a new rate is challenged by protest and investigated by the FERC, the FERC may suspend collection of such new rate for up to seven months. If such new rate is found to be unjust and unreasonable, the FERC may order refunds of amounts collected in excess of amounts generated by the just and reasonable rate determined by the FERC. A successful rate challenge could result in a common carrier paying refunds together with interest for the period that the rate was in effect. In addition, shippers may challenge by complaint tariff rates and terms and conditions of service even after the rates and terms and conditions of service are in effect. If the FERC, in response to such a complaint or on its own initiative, initiates an investigation of rates that are already in effect, the FERC may order a carrier to change its rates prospectively. If existing rates are challenged and are determined by the FERC to be in excess of a just and reasonable level,

22

Table of Contents

any complaining shipper may obtain reparations for damages sustained during the two years prior to the date the shipper filed a complaint.

NuStar Energy is able to use various FERC-authorized rate change methodologies for its interstate pipelines, including indexed rates, cost-of-service rates, market-based rates and settlement rates. Typically, NuStar Energy adjusts its rates annually in accordance with FERC indexing methodology, which currently allows a pipeline to change its rates within prescribed ceiling levels that are tied to an inflation index. For the five-year period beginning July 1, 2011, the index was measured by the year-over-year change in the Bureau of Labor’s producer price index for finished goods, plus 2.65%. For the five-year period beginning July 1, 2016, the current index is measured by the year-over-year change in the Bureau of Labor’s producer price index for finished goods, plus 1.23%. Further, some of NuStar Energy’s newer projects that involved an open season include negotiated indexation rate caps.

In October 2016, the FERC initiated an Advance Notice of Proposed Rulemaking (ANOPR) to determine whether to require oil pipeline companies to file cost and revenue data for each of the company’s pipeline systems, with the definition of such systems also part of the ANOPR. Among other things, the ANOPR also proposed that index rate adjustments be capped or prohibited under certain circumstances and that ceiling rates be capped under certain circumstances. These methodologies, if adopted, could result in changes in NuStar Energy’s revenue that do not fully reflect changes in costs it incurs to operate and maintain its pipelines. For example, NuStar Energy’s costs could increase more quickly or by a greater amount than the negotiated or, if adopted, FERC-mandated indexation rate cap.

The reporting of system-based cost and revenue data, if adopted as a result of the ANOPR, could lead to an increase in rate litigation at the FERC. Currently, shippers may protest rate increases made within the ceiling levels, but such protests must show that the portion of the rate increase resulting from application of the index is substantially in excess of the pipeline’s change in costs from the previous year. However, if the index results in a negative adjustment, NuStar Energy is required to reduce any rates that exceed the new maximum allowable rate. In addition, changes in the index might not be large enough to fully reflect actual increases in NuStar Energy’s costs. If the FERC’s rate-making methodologies change, any such change or new methodologies could result in rates that generate lower revenues and cash flow and could adversely affect NuStar Energy’s ability to make distributions to its unitholders, including us, and to meet its debt service requirements. Additionally, because competition constrains NuStar Energy’s rates in various markets, NuStar Energy may from time to time be forced to reduce some of its rates to remain competitive.

Changes to FERC rate-making principles or pronouncements could have an adverse impact on NuStar Energy’s ability to recover the full cost of operating its pipeline facilities and its ability to make distributions to its unitholders, including us.
In May 2005, the FERC issued a statement of general policy stating it will permit pipelines to include in their costs of service a tax allowance to reflect actual or potential tax liability on their public utility income attributable to all partnership or limited liability company interests, if the ultimate owner of the interest has an actual or potential income tax liability on such income. Whether a pipeline’s owners have such actual or potential income tax liability will be reviewed by the FERC on a case-by-case basis. Although this policy is generally favorable for pipelines that are organized as pass-through entities, it still entails rate risk due to the case-by-case review requirement. This tax allowance policy and the FERC’s application of that policy were appealed to the D.C. Circuit, and, on May 29, 2007, the D.C. Circuit issued an opinion upholding the FERC’s tax allowance policy.

In two proceedings involving SFPP, L.P., a refined products pipeline system, shippers again challenged the FERC’s income tax allowance policy, alleging that it is unlawful for a pipeline organized as a tax-pass-through entity to be afforded an income tax allowance and that the income tax allowance is unnecessary because an allowance for income taxes for such pipelines is recovered indirectly through the rate of return on equity. The FERC rejected these shipper arguments in multiple orders. Petitions for review of the FERC’s rulings on the income tax allowance were filed with the D.C. Circuit.

On July 1, 2016, the D.C. Circuit issued an opinion granting the shippers’ petition for review of the FERC’s rulings on the income tax allowance, finding that the FERC had failed to demonstrate that there is no double recovery of taxes for partnerships that receive an income tax allowance in addition to the return they receive through the rate of return on equity. On this basis, the D.C. Circuit remanded the issue to the FERC, which established a pending industrywide Notice of Inquiry regarding this issue. Certain participants in the Notice of Inquiry made filings claiming that pipeline rates should be reduced based on anticipated income tax reductions related to the Tax Cuts and Jobs Act. Because the extent to which an interstate oil pipeline organized as a partnership is entitled to an income tax allowance is subject to a case-by-case review at the FERC and is a matter that remains under litigation and FERC review, the level of income tax allowance to which NuStar Energy would ultimately be entitled is not certain. The manner in which the FERC’s income tax allowance policy is applied to pipelines owned by publicly traded partnerships could limit NuStar Energy’s ability to include a full income tax allowance in its cost of service.

The rates that NuStar Energy may charge on its interstate ammonia pipeline are subject to regulation by the STB.
NuStar Energy’s ammonia pipeline is subject to regulation under the Interstate Commerce Act by the STB, which is part of the DOT. Under that regulation NuStar Energy’s ammonia pipeline’s rates, rules and practices related to the interstate transportation of anhydrous ammonia must be reasonable and, in providing interstate transportation, NuStar Energy’s ammonia pipeline may not subject a shipper to unreasonable discrimination.

Increases in natural gas and power prices could adversely affect NuStar Energy’s operating expenses and its ability to make distributions to its unitholders, including us.
Power costs constitute a significant portion of NuStar Energy’s operating expenses. For the year ended December 31, 2017, NuStar Energy’s power costs equaled approximately $46.0 million, or 10.2% of NuStar Energy’s operating expenses for the year. NuStar Energy uses mainly electric power at its pipeline pump stations and terminals, and such electric power is furnished by various utility companies that primarily use natural gas to generate electricity. Accordingly, NuStar Energy’s power costs typically fluctuate with natural gas prices, and increases in natural gas prices may cause NuStar Energy’s power costs to increase further. If natural gas prices increase, NuStar Energy’s cash flows may be adversely affected, which could adversely affect NuStar Energy’s ability to make distributions to its unitholders, including us.

Terrorist attacks and the threat of future attacks worldwide, as well as continued hostilities in the Middle East or other sustained military campaigns, may adversely impact NuStar Energy’s results of operations.
The United States Department of Homeland Security has identified pipelines and other energy infrastructure assets as ones that might be specific targets of terrorist organizations. These potential targets might include NuStar Energy’s pipeline systems, storage facilities or operating systems and may affect its ability to operate or control its pipeline and storage assets. Increased security measures taken by NuStar Energy as a precaution against possible terrorist attacks have resulted in increased costs to its business. Uncertainty surrounding continued hostilities in the Middle East or other sustained military campaigns may affect NuStar Energy’s operations in unpredictable ways, including disruptions of crude oil supplies and markets for refined products, instability in the financial markets that could restrict NuStar Energy’s ability to raise capital and the possibility that infrastructure facilities could be direct targets of, or indirect casualties of, an attack.

Hedging transactions may limit NuStar Energy’s potential gains or result in significant financial losses.
While intended to reduce the effects of volatile commodity prices, hedging transactions, depending on the hedging instrument used, may limit NuStar Energy’s potential gains if petroleum product prices were to rise substantially over the price established by the hedge. In addition, such transactions may expose NuStar Energy to the risk of financial loss in certain circumstances, including instances in which there is a change in the expected differential between the underlying price in the hedging agreement and the actual prices received.

The accounting standards regarding hedge accounting are complex and, even when NuStar Energy engages in hedging transactions that are effective economically, these transactions may not be considered effective for accounting purposes. Accordingly, NuStar Energy’s financial statements will reflect increased volatility due to these hedges, even when there is no underlying economic impact at that point. It is not possible for NuStar Energy to engage in a hedging transaction that completely mitigates its exposure to commodity prices, and NuStar Energy’s financial statements may reflect a gain or loss arising from an exposure to commodity prices for which NuStar Energy is unable to enter into an effective hedge.

NuStar Energy’s purchase and sale of crude oil and petroleum products may expose NuStar Energy to trading losses and hedging losses, and non-compliance with NuStar Energy’s related risk management policies could result in significant financial losses.
Although NuStar Energy’s marketing and trading of crude oil and petroleum products represents a small percentage of its overall business, these activities expose NuStar Energy to some commodity price volatility risk for the purchase and sale of crude oil and petroleum products, including distillates and fuel oil. NuStar Energy attempts to mitigate this volatility risk through hedging, but it is still exposed to basis risk and may be required to post cash collateral under its hedging arrangements. NuStar Energy also may be exposed to inventory and financial liquidity risk due to the inability to trade certain products or rising costs of carrying some inventories. Further, NuStar Energy’s marketing and trading activities, including any hedging activities, may cause volatility in NuStar Energy’s earnings. In addition, NuStar Energy will be exposed to credit risk in the event of non-performance by counterparties.

NuStar Energy’s risk management policies may not eliminate all price risk since open trading positions will expose it to price volatility, and there is a risk that NuStar Energy’s risk management policies will not be complied with. Although NuStar Energy has designed procedures to anticipate and detect non-compliance, there are no assurances these steps will detect and prevent all violations of NuStar Energy’s trading policies and procedures, particularly if deception and other intentional misconduct are involved.

As a result of the risks described above, the activities associated with NuStar Energy’s marketing and trading business may expose NuStar Energy to volatility in earnings and financial losses, which may adversely affect its financial condition and ability to make its quarterly distributions to its unitholders, including us.

TAX RISKS TO OUR UNITHOLDERS

If we or NuStar Energy were treated as a corporation for federal or state income tax purposes or we or NuStar Energy were otherwise subject to a material amount of entity-level taxation, then our cash available for distribution to our unitholders would be substantially reduced.
The anticipated after-tax benefit of an investment in our units depends largely on our being treated as a partnership for federal income tax purposes. We have not requested, and do not plan to request, a ruling from the Internal Revenue Service (the IRS) on this matter.
The value of our investment in NuStar Energy depends largely on NuStar Energy being treated as a partnership for federal income tax purposes.

Despite the fact that we are a limited liability company and NuStar Energy is a limited partnership under Delaware law, we would each be treated as a corporation for federal income tax purposes unless each of us satisfies a “qualifying income” requirement. Based upon our current operations, we believe we and NuStar Energy each satisfy the qualifying income requirement. Failing to meet the qualifying income requirement or a change in current law could cause us or NuStar Energy to be treated as a corporation for federal income tax purposes or otherwise subject us or NuStar Energy to taxation as an entity.

If we were treated as a corporation for federal income tax purposes, we would pay federal income tax on our taxable income at the corporate tax rate and would likely pay state and local income tax at varying rates. Distributions to unitholders who are treated as holders of corporate stock would generally be taxed again as corporate dividends (to the extent of our current and accumulated earnings and profits), and no income, gains, losses, deductions or credits would flow through to unitholders. If NuStar Energy were treated as a corporation for federal income tax purposes, it would pay federal income tax on its taxable income at the corporate tax rate. Distributions to us would generally be taxed again as corporate distributions, and no income, gains, losses, deductions or credits would flow through to us. Because a tax would be imposed upon us or NuStar Energy as a corporation, our distributable cash flow would be substantially reduced.

Moreover, changes in current state law may subject us or NuStar Energy to entity-level taxation by individual states. Because of widespread state budget deficits and other reasons, several states are evaluating ways to subject entities treated as partnerships to entity-level taxation through the imposition of state income, franchise and other forms of taxation. Imposition of any such taxes or an increase in the existing tax rates would substantially reduce the cash available for distribution to unitholders. Therefore, if we or NuStar Energy were treated as a corporation for federal income tax purposes or otherwise subjected to a material amount of entity-level taxation, there would be a material reduction in the anticipated cash flow and after-tax return to our unitholders, likely causing a substantial reduction in the value of our common units.

The tax treatment of publicly traded entities treated as partnerships for federal income tax purposes, or an investment in our or NuStar Energy units, could be subject to potential legislative, judicial or administrative changes or differing interpretations, possibly applied on a retroactive basis.
The present U.S. federal income tax treatment of publicly traded entities treated as partnerships for federal income tax purposes, including us or NuStar Energy, or an investment in our or NuStar Energy’s units may be modified by administrative, legislative or judicial changes or differing interpretations at any time. From time to time, members of Congress propose and consider such substantive changes to the existing federal income tax laws that affect such entities. Further, final Treasury regulations under Section 7704(d)(1)(E) of the Code published in the Federal Register interpret the scope of qualifying income requirements for publicly traded partnerships by providing industry-specific guidance. We do not believe the final Treasury regulations affect our or NuStar Energy’s ability to be treated as partnerships for U.S. federal income tax purposes.

In addition, the Tax Cuts and Jobs Act enacted December 22, 2017 makes significant changes to the U.S. federal income tax rules applicable to both individuals and entities, including changes to the tax rate on a unitholder’s allocable share of income from a publicly traded entity. The Tax Cuts and Jobs Act is complex and lacks administrative guidance. Thus, the impact of certain aspects of its provisions on us or an investment in our units is currently unclear. Unitholders should consult their tax advisor regarding the Tax Cuts and Jobs Act and its effect on us or an investment in our units.

Any changes to the federal income tax laws and interpretations thereof (including administrative guidance relating to the Tax Cuts and Jobs Act) may be applied retroactively and could make it more difficult or impossible for us or NuStar Energy to meet the exception for certain publicly traded entities to be treated as partnerships for federal income tax purposes or otherwise adversely affect our business, financial condition or results of operations. We are unable to predict whether any additional

25

Table of Contents

changes or other proposals will ultimately be enacted. Any such changes could negatively impact the value of an investment in our units.

A successful IRS contest of the federal income tax positions we or NuStar Energy take may adversely impact the market for our or NuStar Energy’s units, and the costs of any contest will reduce cash available for distribution to our unitholders.
The IRS may adopt positions that differ from the positions we or NuStar Energy take, even positions taken with the advice of counsel. It may be necessary to resort to administrative or court proceedings to sustain some or all of the positions we or NuStar Energy take. A court may not agree with all of the positions we or NuStar Energy take. Any contest with the IRS may affect adversely the taxable income reported to our unitholders and the income taxes they are required to pay. As a result, any such contest with the IRS may materially and adversely impact the market for our or NuStar Energy’s units and the prices at which they trade. In addition, the costs of any contest between NuStar Energy and the IRS will result in a reduction in cash available for distribution to NuStar Energy unitholders and thus will be borne indirectly by us, as a unitholder and as the owner of the general partner of NuStar Energy, and by other unitholders of NuStar Energy.

If the IRS makes audit adjustments to our or NuStar Energy’s income tax returns for tax years beginning after December 31, 2017, it (and some states) may assess and collect any taxes (including any applicable penalties and interest) resulting from such audit adjustment directly from us or NuStar Energy, in which case we or NuStar Energy, as applicable, may elect to either pay the taxes directly to the IRS or to have its unitholders and former unitholders take such audit adjustment into account and pay any resulting taxes. If we or NuStar Energy bears such payment, our cash available for distribution to our unitholders might be substantially reduced .
Pursuant to the Bipartisan Budget Act of 2015, for tax years beginning after December 31, 2017, if the IRS makes audit adjustments to our or NuStar Energy’s income tax returns, it (and some states) may assess and collect any taxes (including any applicable penalties and interest) resulting from such audit adjustment directly from us or NuStar Energy, as applicable. To the extent possible under the new rules, we may elect to either pay the taxes (including any applicable penalties and interest) directly to the IRS or, if we are eligible, issue a revised Schedule K-1 to each unitholder with respect to an audited and adjusted return. Although we or NuStar Energy’s general partner, as applicable, may elect to have our unitholders and former unitholders take such audit adjustment into account and pay any resulting taxes (including applicable penalties or interest) in accordance with their interests in us during the tax year under audit, there can be no assurance that such election will be practical, permissible or effective in all circumstances. As a result, our current unitholders may bear some or all of the tax liability resulting from such audit adjustment, even if such unitholders did not own common units in us during the tax year under audit. If, as a result of any such audit adjustment, we or NuStar Energy make payments of taxes, penalties and interest, our cash available for distribution to our unitholders might be substantially reduced.

Even if unitholders do not receive any cash distributions from us, they will be required to pay taxes on their respective share of our taxable income.
Unitholders will be required to pay federal income taxes and, in some cases, state and local income taxes on their respective share of our taxable income, whether or not the unitholders receive cash distributions from us. Unitholders may not receive cash distributions from us equal to their respective share of our taxable income or even equal to the actual tax liability that results from their respective share of our taxable income.

Tax gain or loss on the disposition of our units could be different than expected.
If a unitholder sells units, the selling unitholder will recognize a gain or loss equal to the difference between the amount realized and the unitholder’s tax basis in those units. Prior distributions to the selling unitholder in excess of the total net taxable income the unitholder was allocated for a unit, which decreased the unitholder’s tax basis in that unit, will, in effect, become taxable income to the selling unitholder if the unit is sold at a price greater than the unitholder’s tax basis in that unit, even if the price the unitholder receives is less than the units’ original cost. A substantial portion of the amount realized, whether or not representing gain, may be ordinary income to the selling unitholder.

Unitholders may be subject to limitations on their ability to deduct interest expense incurred by us.
In general, we are entitled to a deduction for interest paid or accrued on indebtedness properly allocable to our trade or business during our taxable year, and NuStar Energy is entitled to a deduction for interest paid or accrued on indebtedness properly allocable to its trade or business during its taxable year. However, under the Tax Cuts and Jobs Act, for taxable years beginning after December 31, 2017, a deduction for “business interest” is limited to the sum of a taxpayer’s business interest income plus 30% of its “adjusted taxable income.” This limitation is applied at the entity level for entities treated as partnerships for federal income tax purposes, including us and NuStar Energy. For the purposes of this limitation, adjusted taxable income is computed without regard to any business interest expense or business interest income, and in the case of taxable years beginning before January 1, 2022, any deduction allowable for depreciation, amortization, or depletion. Any interest disallowed at the entity level may be carried forward and deducted in future years by the partner from his share of the entity’s “excess taxable income,”

26

Table of Contents

which is generally equal to the excess of 30% of its adjusted taxable income over the amount of its deduction for business interest for such future taxable year, subject to certain restrictions.

Tax-exempt entities face unique tax issues from owning our units that may result in adverse tax consequences to them.
Investment in our units by tax-exempt entities, such as employee benefit plans and individual retirement accounts (known as IRAs) raises issues unique to them. For example, virtually all of our income allocated to organizations that are exempt from U.S. federal income tax, including IRAs and other retirement plans, will be unrelated business taxable income and will be taxable to them. Further, with respect to taxable years beginning after December 31, 2017, a tax-exempt entity with more than one unrelated trade or business (including by attribution from investment in us or NuStar Energy that is engaged in one or more unrelated trades or businesses) is required to compute the unrelated business taxable income of such tax-exempt entity separately with respect to each such trade or business (including for purposes of determining any net operating loss deduction). As a result, for years beginning after December 31, 2017, it may not be possible for tax-exempt entities to utilize losses from an investment in us to offset unrelated business taxable income from another unrelated trade or business and vice versa. Tax-exempt entities should consult a tax advisor before investing in our units.

Non-U.S. unitholders will be subject to U.S. taxes and withholding with respect to their income and gain from owning our units.
Non-U.S. unitholders are subject to U.S. federal income tax on income effectively connected with a U.S. trade or business (“effectively connected income”). A unitholder’s share of our income, gain, loss and deduction, and any gain from the sale or disposition of our units will generally be considered to be “effectively connected” with a U.S. trade or business and subject to U.S. federal income tax. Additionally, distributions to a non-U.S. unitholder will be subject to withholding at the highest applicable effective tax rate.

The Tax Cuts and Jobs Act imposes a withholding obligation of 10% of the amount realized upon a non-U.S. unitholder’s sale or disposition of units. The IRS has temporarily suspended the application of the withholding requirements on sales of publicly traded interests, including our units, pending promulgation of regulations or other guidance. It is not clear if or when such regulations or other guidance will be issued. Non-U.S. unitholders should consult a tax advisor before investing in our units.

We will treat each purchaser of our units as having the same tax benefits without regard to the units purchased. The IRS may challenge this treatment, which could adversely affect the value of our units.
Because we cannot match transferors and transferees of units, we will adopt depreciation and amortization positions that may not conform with all aspects of existing Treasury regulations. A successful IRS challenge to those positions could adversely affect the amount of tax benefits available to unitholders. It also could affect the timing of these tax benefits or the amount of gain from a unitholder’s sale of units and could have a negative impact on the value of our units or result in audit adjustments to the unitholder’s tax returns.

Unitholders will likely be subject to state and local taxes and return filing requirements as a result of investing in our units.
In addition to federal income taxes, unitholders will likely be subject to other taxes, such as state and local income taxes, unincorporated business taxes and estate, inheritance or intangible taxes that are imposed by the various jurisdictions in which we or NuStar Energy do business or own property. Unitholders will likely be required to file state and local income tax returns and pay state and local income taxes in some or all of these various jurisdictions. Further, unitholders may be subject to penalties for failure to comply with those requirements. We or NuStar Energy may own property or conduct business in other states or foreign countries in the future. It is each unitholder’s responsibility to file all federal, state and local tax returns.

We prorate our items of income, gain, loss and deduction between transferors and transferees of our units each month based upon the ownership of our units on the first day of each month, instead of on the basis of the date a particular unit is transferred. The IRS may challenge this treatment, which could change the allocation of items of income, gain, loss and deduction among our unitholders.
We prorate our items of income, gain, loss and deduction between transferors and transferees of our units each month based upon the ownership of our units on the first day of each month, instead of on the basis of the date a particular unit is transferred. The U.S. Treasury Department and the IRS recently issued final regulations pursuant to which a publicly traded entity treated as a partnership for federal income tax purposes may use a similar monthly simplifying convention to allocate tax items among transferor and transferee unitholders although such tax items must be prorated on a daily basis and the regulations do not specifically authorize all aspects of the proration method we have currently adopted. If the IRS were to challenge our proration method, we may be required to change the allocation of items of income, gain, loss and deduction among our unitholders.

Table of Contents

We and NuStar Energy have adopted certain valuation methodologies in determining a unitholder’s allocations of income, gain, loss and deduction. The IRS may challenge these methods or the resulting allocations and such a challenge could adversely affect the value of our investment in NuStar Energy.
In determining the items of income, gain, loss and deduction allocable to our and NuStar Energy’s common unitholders, we and NuStar Energy must routinely determine the fair market value of our respective assets. Although we or NuStar Energy may from time to time consult with professional appraisers regarding valuation matters, we and NuStar Energy make valuation estimates using a methodology based on the fair market value of our respective common units as a means to measure the fair market value of our respective assets. The IRS may challenge these valuation methods and the resulting allocations of income, gain, loss and deduction.

A successful IRS challenge to these methods or allocations could adversely affect the amount of taxable income or loss being allocated to our unitholders or the NuStar Energy common unitholders. It also could affect the amount of gain on the sale of common units by NuStar Energy’s common unitholders and our unitholders and could have a negative impact on our investment in NuStar Energy or result in audit adjustments to the tax returns of our or NuStar Energy’s common unitholders without the benefit of additional deductions.

We expect that our ratio of taxable income to cash distributions will be higher than the ratio applicable to holders of common units in NuStar Energy.
We expect that our ratio of taxable income to cash distributions will be higher than the ratio applicable to holders of common units in NuStar Energy. Other holders of common units in NuStar Energy will receive remedial allocations of deductions from NuStar Energy. Any remedial allocations of deductions to us from NuStar Energy will be very limited. In addition, our ownership of NuStar Energy incentive distribution rights will cause more taxable income to be allocated to us from NuStar Energy. If NuStar Energy is successful in increasing its distributions over time, our income allocations from our NuStar Energy incentive distribution rights will increase, and, therefore, our ratio of taxable income to cash distributions will increase.

Items of our income, gain, loss and deduction will be allocated among our unitholders to account for the difference between the fair market value and tax basis of our assets at the time of an offering.
Specified items of income, gain, loss and deduction will be allocated to us from NuStar Energy and among our unitholders to account for the difference between the fair market value and tax basis of NuStar Energy’s assets and our assets at the time the assets were contributed to NuStar Energy (or its predecessors) or at any other offering. The effect of these allocations will be to allocate to us from NuStar Energy and to our unitholders, gains attributable to our share of the difference between the fair market value and the tax basis of NuStar Energy’s assets at these times (including gain attributable to our ownership of the incentive distribution rights). The effect of these allocations to a unitholder purchasing units will be essentially the same as if the tax basis of our and NuStar Energy’s assets were equal to their fair market values at the time of the purchase, with the result that a unitholder purchasing units will not bear the federal income tax burden associated with any existing difference between the fair market value and tax basis of our or NuStar Energy’s assets. The federal income tax burden associated with the difference between the fair market value and the tax basis of our assets immediately prior to purchasing units will be borne by our existing unitholders as of that time.

A unitholder whose units are the subject of a securities loan (e.g., a loan to a “short seller” to cover a short sale of units) may be considered as having disposed of those units. If so, the unitholder would no longer be treated for tax purposes as a partner with respect to those units during the period of the loan and may recognize gain or loss from the disposition.
Because there are no specific rules governing the federal income tax consequences of loaning an interest in an entity treated as a partnership for federal income tax purposes, a unitholder whose units are the subject of a securities loan may be considered as having disposed of the loaned units. In that case, the unitholder may no longer be treated for tax purposes as a partner with respect to those units during the period of the loan to the short seller and the unitholder may recognize gain or loss from such disposition. Moreover, during the period of the loan, any of our income, gain, loss or deduction with respect to those units may not be reportable by the unitholder and any cash distributions received by the unitholder as to those units could be fully taxable as ordinary income. Unitholders desiring to assure their status as partners for tax purposes and avoid the risk of gain recognition from a loan to a short seller are urged to consult a tax advisor to discuss whether it is advisable to modify any applicable brokerage account agreements to prohibit their brokers from borrowing their units.

Our only cash generating assets are our ownership interests in NuStar Energy L.P. (NuStar Energy), a publicly traded Delaware limited partnership (NYSE: NS). As of December 31, 2017 , we have an approximate 13% ownership interest in NuStar Energy, consisting of the following:
the general partner interest;
100% of the incentive distribution rights issued by NuStar Energy, which entitle us to receive increasing percentages of the cash distributed by NuStar Energy, currently at the maximum percentage of 23% ; and
10,214,626 common units of NuStar Energy.

We account for our investment in NuStar Energy using the equity method. Therefore, our financial results reflect a portion of NuStar Energy’s net income based on our ownership interest. We have no separate operating activities apart from those conducted by NuStar Energy and therefore generate no revenues from operations.

NuStar Energy is engaged in the transportation of petroleum products and anhydrous ammonia and the terminalling, storage and marketing of petroleum products. NuStar Energy has pipelines in the United States, as well as terminal and storage facilities in the United States, Canada, Mexico, the Netherlands, including St. Eustatius in the Caribbean, and the United Kingdom. NuStar Energy conducts its operations through its subsidiaries, primarily NuStar Logistics, L.P. (NuStar Logistics) and NuStar Pipeline Operating Partnership L.P. Unless otherwise indicated, the terms “NuStar GP Holdings,” “NSH,” “we,” “our” and “us” are used in this report to refer to NuStar GP Holdings, LLC, to one or more of our consolidated subsidiaries or to all of them taken as a whole.

NuStar Energy’s partnership agreement requires that it distribute all available cash to its common limited partners and general partner each quarter. Available cash is generally defined as cash receipts less cash disbursements (including distributions to holders of NuStar Energy’s preferred units) and cash reserves established by NuStar Energy’s board of directors, in its sole discretion. Similarly, we are required by our limited liability company agreement to distribute all of our available cash at the end of each quarter, generally defined in our limited liability company agreement as cash on hand at the end of the quarter, less reserves established by our board of directors.

Merger. On February 7, 2018, NuStar GP Holdings, NuStar Energy, Riverwalk Logistics, L.P., NuStar GP, LLC, Marshall Merger Sub LLC, a wholly owned subsidiary of NuStar Energy (Merger Sub), and Riverwalk Holdings, LLC entered into an Agreement and Plan of Merger (the Merger Agreement) pursuant to which Merger Sub will merge with and into NuStar GP Holdings with NuStar GP Holdings being the surviving entity (the Merger), such that NuStar Energy will be our sole member following the Merger. Pursuant to the Merger Agreement and at the effective time of the Merger, NuStar Energy’s partnership agreement will be amended and restated to, among other things, (i) cancel the incentive distribution rights, (ii) convert the 2% general partner interest in NuStar Energy into a non-economic management interest and (iii) provide the holders of NuStar Energy’s common units with voting rights in the election of the members of the board of directors of NuStar GP, LLC at an annual meeting, beginning in 2019. The Merger is subject to the satisfaction or waiver of certain conditions, including approval

of the Merger Agreement by our unitholders. Please refer to Note 15 of the Notes to Consolidated Financial Statements in Item 8. “Financial Statements and Supplementary Data” for further discussion of the Merger.

Employee Transfer from NuStar GP, LLC
On March 1, 2016, NuStar GP, LLC, our wholly owned subsidiary, transferred and assigned to NuStar Services Company LLC (NuStar Services Co), a wholly owned subsidiary of NuStar Energy, all of NuStar GP, LLC’s employees and related benefit plans, programs, contracts and policies (the Employee Transfer). Our officers, who are also officers of NuStar GP, LLC, are now dual employees of NuStar GP, LLC and NuStar Services Co. The Employee Transfer did not materially change our results of operations since NuStar Energy previously reimbursed us for nearly all of NuStar GP, LLC’s employee costs. However, as a result of the Employee Transfer, NuStar Services Co pays employee costs directly and sponsors the 2000 Long-Term Incentive Plan and other employee benefit plans. Please refer to Note 5 of the Notes to Consolidated Financial Statements in Item 8. “Financial Statements and Supplementary Data” for further discussion on the Employee Transfer.

NuStar Energy’s Acquisitions
Navigator Acquisition and Financing Transactions. On May 4, 2017, NuStar Energy completed the acquisition of Navigator Energy Services, LLC for approximately $1.5 billion (the Navigator Acquisition). In order to fund the purchase price, NuStar Energy issued 14,375,000 common units for net proceeds of $657.5 million , NuStar Logistics issued $550.0 million of 5.625% senior notes for net proceeds of $543.3 million and NuStar Energy issued 15,400,000 of its 7.625% Series B Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units for net proceeds of $371.8 million . In conjunction with the Navigator Acquisition, NuStar Energy’s partnership agreement was amended and restated to, among other things, provide a waiver of certain quarterly distributions with respect to our incentive distribution rights. In April 2017, we borrowed approximately $14.0 million under our revolving credit facility to fund a contribution to NuStar Energy in order to maintain our 2% general partner interest in connection with NuStar Energy’s issuance of common units. Please refer to Note 4 of the Notes to Consolidated Financial Statements in Item 8. “Financial Statements and Supplementary Data” for a discussion of these transactions.

Martin Terminal Acquisition. On December 21, 2016 , NuStar Energy acquired crude oil and refined product storage assets in Corpus Christi, TX for $95.7 million , including $2.1 million of capital expenditure reimbursements, from Martin Operating Partnership L.P. The assets acquired include 900,000 barrels of crude oil storage capacity, 250,000 barrels of refined product storage capacity and exclusive use of the Port of Corpus Christi’s new crude oil dock.

Linden Acquisition. On January 2, 2015, NuStar Energy acquired full ownership of ST Linden Terminal, LLC, which owns a refined products terminal in Linden, NJ, for $142.5 million (the Linden Acquisition). Prior to the Linden acquisition, the terminal operated as a joint venture between NuStar Energy and Linden Holding Corp., with each party owning 50% .

RESULTS OF OPERATIONS

As discussed above, we account for our investment in NuStar Energy using the equity method. As a result, our equity in earnings of NuStar Energy, our only source of income, directly fluctuates with the amount of NuStar Energy’s distributions and results of operations. NuStar Energy’s distributions to its common limited partners determine the amount of our incentive distribution earnings, while NuStar Energy’s results of operations determine the amounts of earnings attributable to our general partner and common limited partner interests.

NuStar Energy’s net income slightly decreased for the year ended December 31, 2017 , compared to the year ended December 31, 2016 . The decrease in other expense, net, mainly resulting from a $58.7 million impairment charge in 2016 on NuStar Energy’s term loan to Axeon Specialty Products, was offset by increased interest expense, increased general and administrative expenses and decreased segment operating income.

Our equity in earnings in NuStar Energy decreased $4.5 million for the year ended December 31, 2017 , compared to the year ended December 31, 2016 , primarily due to a decrease in our equity in earnings related to our general and common limited partner interests. NuStar Energy issued preferred units in the fourth quarter of 2016 and in the second and fourth quarters of 2017, and NuStar Energy’s earnings are first allocated to its preferred units in an amount equal to its earned distributions. Accordingly, earnings allocated to our general and common limited partner interests for year ended December 31, 2017 were reduced by the amount of NuStar Energy’s earnings allocated to the preferred limited partner interests, as well as to higher IDRs.

Our equity in earnings of NuStar Energy related to our IDRs increased as a result of NuStar Energy’s issuances of common units in 2016 and in April of 2017. Our IDRs in NuStar Energy entitle us to an increasing amount of NuStar Energy’s cash distributions. In connection with the Navigator Acquisition, we amended NuStar Energy’s partnership agreement to waive our IDRs related to NuStar Energy’s common units issued in April of 2017 for ten consecutive quarters beginning with the distribution earned for the second quarter of 2017 up to a maximum of $22.0 million. Please refer to Notes 4 and 6 of the Consolidated Financial Statements in Item 8. “Financial Statements and Supplementary Data” for a more detailed discussion of the incentive distribution waiver and of how NuStar Energy’s distributions are allocated.

General
For the years ended December 31, 2017 and 2016 , we recognized other income, net of $41.9 million and $3.0 million , respectively, mainly due to gains resulting from NuStar Energy’s issuances of common units, calculated as if we had sold a proportionate share of our investment in NuStar Energy.
Income tax (expense) benefit changed by $1.9 million for the year ended December 31, 2017 , compared to the year ended December 31, 2016 , primarily due to the U.S. corporate tax rate reduction from 35% to 21% due to the Tax Cuts and Jobs Act (“the Act”) enacted on December 22, 2017. Please refer to Note 13 of the Notes to Consolidated Financial Statements in Item 8. “Financial Statements and Supplementary Data” for a discussion on income taxes.

NuStar Energy’s net income decreased $156.7 million for the year ended December 31, 2016 , compared to the year ended December 31, 2015 , primarily due to a $58.7 million impairment charge in 2016 on NuStar Energy’s term loan to Axeon Specialty Products and a $56.3 million gain associated with NuStar Energy’s Linden Acquisition in 2015. In addition, NuStar Energy’s segment operating income decreased $35.3 million , resulting mainly from reductions in operating income for its pipeline and fuels marketing segments.

Our equity in earnings related to our general and common limited partner interests in NuStar Energy decreased $23.6 million for the year ended December 31, 2016 , compared to the year ended December 31, 2015 , due to a decrease in NuStar Energy’s net income. However, our equity in earnings of NuStar Energy related to our IDRs increased slightly as a result of NuStar Energy’s issuances of common units in 2016. Our IDRs in NuStar Energy entitle us to an increasing amount of NuStar Energy’s cash distributions. Please refer to Note 6 of the Consolidated Financial Statements in Item 8. “Financial Statements and Supplementary Data” for a more detailed discussion of how NuStar Energy’s distributions are allocated.

Other Income (Expense), Net
For the year ended December 31, 2016 , we recognized other income of $3.0 million , mainly due to gains of $2.4 million as a result of NuStar Energy’s issuances of common units in 2016. The gains represent the increase in the value of our proportionate share of NuStar Energy’s capital. For the year ended December 31, 2015 , we recognized other expense of $2.3 million, due to losses of $2.3 million on the sale of NuStar Energy L.P. common limited partner units in connection with unit-based compensation plans we sponsored prior to the Employee Transfer.



38


TRENDS AND OUTLOOK

As discussed in more detail in Note 15 of the Notes to Consolidated Financial Statements in Item 8. “Financial Statements and Supplementary Data,” we and NuStar Energy entered into the Merger Agreement to simplify our corporate structure. At the closing of the Merger, which is subject to, among other things, approval of our unitholders: (i) NuStar Energy will issue 0.55 of an NS common unit for each outstanding NSH unit; (ii) our economic rights in the 2% general partner interest, the incentive distribution rights (the IDRs) in NS and the NS common units held by us will be cancelled; and (iii) NS will pay off and cancel our obligations under our revolving credit agreement.

NuStar Energy believes simplifying the corporate structure and eliminating the IDRs will lower NuStar Energy’s cost of capital and create a more efficient and transparent structure. In addition, NuStar Energy’s management anticipates recommending, and the NuStar Energy board of directors indicated it intends to approve, resetting NuStar Energy’s quarterly distribution from $1.095 per common unit to $0.60 per common unit, effective with the first quarter 2018 distribution. NuStar Energy expects that resetting its distribution will improve its ability to fund cash requirements immediately, and, in the longer-term, will also serve to improve its leverage metrics and reduce its future need to access the capital markets.

Historically, master limited partnerships (MLPs), like NuStar Energy, have typically funded strategic capital expenditures and acquisitions from external sources, primarily through borrowings under revolving credit agreements and issuance of equity and debt securities. In the past few years, the total number of, and aggregate amount raised by, MLP common equity issuances has dropped dramatically, and MLPs with low coverage and high leverage have found it increasingly difficult to issue common equity. Through the combination of the simplification and distribution reset discussed above, NuStar Energy expects to be able to fund a larger proportion of its capital projects with the cash generated by its operations, which should, over time, reduce its need to access capital markets to finance future growth opportunities.

During 2017, NuStar Energy’s legacy pipeline systems and storage assets, other than its Permian Crude System, faced 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 of Mexico and significant destruction in the Caribbean. Hurricane Harvey’s heavy rainfall caused only minimal damage to NuStar Energy’s six affected Gulf Coast facilities, but Hurricane Irma passed almost directly over its facility at St. Eustatius, causing a temporary shutdown and inflicting substantial damage. NuStar Energy received hurricane insurance proceeds of $12.5 million in the fourth quarter of 2017 and $87.5 million in January 2018. NuStar Energy expects to recognize a gain in its first quarter 2018 results equal to the amount by which the insurance proceeds received exceed its actual expense incurred during the period, or approximately $85 million. At this time, NuStar Energy expects that costs incurred, over and above its deductible amount, will be covered by the insurance proceeds it has already received. NuStar Energy expects these repairs to continue through next year and into 2020.

Due to that fact that some of NuStar Energy’s current committed shippers’ contracts on its South Texas Crude System expire in the second half of 2018, as well as NuStar Energy’s assessment of the current market conditions in the Eagle Ford, its 2018 forecast reflects its expectation that some of those customers will decline to renew their commitments and demand rates lower than previously contracted rates. As a result, NuStar Energy is projecting lower throughput and rates for the South Texas Crude System in the second half of 2018, which it expects to result in lower revenues for that system during 2018 as compared to 2017.

Since NuStar Energy agrees with the many energy experts who currently predict that backwardation, which tends to decrease demand for storage capacity, will continue through 2018, NuStar Energy’s 2018 forecast reflects lower storage rates and contract renewals at certain of its facilities, which it expects to result in lower revenues for those facilities during 2018 as compared to 2017.

In January 2018, as a result of the widely reported economic strife in Venezuela and the mounting financial and operational challenges facing NuStar Energy’s St. Eustatius anchor tenant, Petróleos de Venezuela, S.A. (PDVSA), NuStar Energy reduced its expectations for PDVSA’s utilization of the terminal during 2018 to reflect a more conservative outlook. In 2017 and this year so far, news outlets around the world have reported the dramatic deterioration of economic conditions in Venezuela, and during 2017, NuStar Energy saw PDVSA’s activity at the terminal decrease to levels well below their historical levels. In addition, in August 2017, the United States imposed sanctions against Venezuela intended to limit PDVSA’s access to credit, and the Trump Administration has announced it may also ban imports of Venezuelan crude into the U.S. and export of U.S. refined products to Venezuela. If implemented, these additional sanctions, together with the current sanctions, could have a significant negative impact on Venezuela and on PDVSA.

Largely due to the impact NuStar Energy believes those negative factors may have on PDVSA and PDVSA’s utilization of its facility, NuStar Energy’s 2018 forecast reflects that its 2018 results of operations of its storage segment will be lower than 2017

39


and that the current forecast properly reflects its conservative assessment of significant uncertainty and risk surrounding PDVSA’s ability to perform this year. That being said, since early January PDVSA’s activity at the terminal has increased, and, if they are able to continue this trend through all or a portion of the year, all other factors remaining constant, NuStar Energy could see improvement in its revenue generated for St. Eustatius, in comparison with its current forecast for 2018, as the year progresses. While NuStar Energy is hopeful that PDVSA will maintain its current activity and continues to work to retain them as an important customer, NuStar Energy also continues to closely monitor PDVSA’s activity and financial well-being and are working to diversify its St. Eustatius facility customer base.

While NuStar Energy’s outlook for 2018 reflects all the challenges it has described, NuStar Energy believes that the consummation of the Merger and its board of director’s approval of its recommended reset to its distribution will immediately increase NuStar Energy’s cash available to pay for capital expenditures, and, over time, will improve its leverage metrics. NuStar Energy expects these steps to strengthen its balance sheet in 2018 and beyond. NuStar Energy also projects that the Permian Crude System will continue to grow, and expects its positive contributions to its pipeline segment’s overall results to grow accordingly.

NuStar Energy’s earnings and the distributions we receive from NuStar Energy directly affect our results. NuStar Energy’s outlook, both overall and for any of its segments, may change, as NuStar Energy bases its expectations on its continuing evaluation of a number of factors, many of which are outside its control. These factors include, but are not limited to, the state of the economy and the capital markets, changes to its 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 its transportation and storage services and changes in laws or regulations affecting its assets.

LIQUIDITY AND CAPITAL RESOURCES

General
Our cash flows consist of distributions from NuStar Energy on our partnership interests, including the incentive distribution rights that we own. Due to our ownership of NuStar Energy’s incentive distribution rights, our portion of NuStar Energy’s total distributions may exceed our ownership interest in NuStar Energy. Our primary cash requirements are for distributions to members, capital contributions to maintain our 2% general partner interest in NuStar Energy (as defined in NuStar Energy’s partnership agreement) in the event that NuStar Energy issues additional common units, debt service requirements, if any, and general and administrative expenses. In addition, because NuStar GP, LLC, a wholly owned subsidiary of NuStar GP Holdings, elected to be treated as a taxable entity in August 2006, we may be required to pay income taxes, which may exceed the amount of tax expense recorded in the consolidated financial statements. We expect to fund our cash requirements primarily with the quarterly cash distributions we receive from NuStar Energy and, if necessary, borrowings under our revolving credit facility.

Pursuant to the Merger Agreement and at the effective time of the Merger, NuStar Energy’s partnership agreement will be amended and restated to, among other things, cancel the incentive distribution rights and convert the 2% general partner interest in NuStar Energy into a non-economic management interest. Furthermore, the 10,214,626 NuStar Energy common units currently owned by us will be cancelled and will cease to exist. As a result, after the Merger, we will no longer receive incentive distributions or quarterly cash distributions related to our ownership interest, from NuStar Energy. At the effective time of the Merger, each of our outstanding common units will be converted into the right to receive 0.55 of a NuStar Energy common unit. All of our common units, when converted, will cease to be outstanding and will automatically be cancelled and no longer exist. NuStar Energy will pay off and cancel our obligations under our revolving credit agreement. Additionally, on February 8, 2018, NuStar Energy announced that NuStar Energy’s management anticipates recommending to the board of directors of NuStar GP, LLC, and expects such board of directors to adopt, a reset of NuStar Energy’s quarterly distribution per common unit to $0.60 ($2.40 on an annualized basis), starting with the first-quarter distribution payable in May 2018. We expect to adjust the quarterly distribution to our members accordingly. Please refer to Note 15 of the Notes to Consolidated Financial Statements in Item 8. “Financial Statements and Supplementary Data” for further discussion of the Merger.

Cash Distributions from NuStar Energy
NuStar Energy distributes all of its available cash to its common limited partners and general partner 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. Available cash is generally defined as cash receipts less cash disbursements (including distributions to holders of NuStar Energy’s preferred units, as further discussed under the Investment in NuStar Energy section below) and cash reserves established by NuStar Energy’s board of directors, in its sole discretion. The following table reflects the cash distributions earned for the periods shown with respect to our ownership interests in NuStar Energy and our incentive distribution rights (IDRs):

Cash Flows for the Years Ended December 31, 2017 , 2016 and 2015
For the years ended December 31, 2017 , 2016 and 2015 , cash distributions received from NuStar Energy were used primarily to fund distributions to our unitholders.

Credit Facility
We amended our revolving credit facility on June 27, 2017 to, among other things, extend its maturity to June 27, 2018 and increase its borrowing capacity from $50.0 million to $60.0 million . The revolving credit agreement allows for the use of up to $10.0 million of its borrowing capacity for letters of credit. Borrowings under our revolving credit facility are used to fund capital contributions to NuStar Energy to maintain our 2% general partner interest when NuStar Energy issues additional common units and to meet other liquidity and capital resource requirements. Our obligations under our revolving credit facility are guaranteed by Riverwalk Holdings, LLC (Riverwalk), our wholly owned subsidiary. Riverwalk has pledged 2,926,833 NuStar Energy common units that it owns to secure its guarantee.

As of December 31, 2017 , we had outstanding borrowings of $42.5 million and availability of $17.5 million for borrowings under our revolving credit facility. Interest on our revolving credit facility is based upon, at our option, either an alternative base rate or a LIBOR-based rate. Our management believes that we are in compliance with the covenants of the revolving credit facility as of December 31, 2017 . Please refer to Note 9 of the Notes to Consolidated Financial Statements in Item 8. “Financial Statements and Supplementary Data” for a detailed discussion on our revolving credit facility.

Investment in NuStar Energy
Issuances of Common Units. On April 18, 2017, NuStar Energy issued 14,375,000 common units representing limited partner interests at a price of $46.35 per unit. NuStar Energy used the net proceeds from this offering of $657.5 million , including our contribution of $13.6 million to maintain our 2% general partner interest, to fund a portion of the purchase price for the Navigator Acquisition. Beginning with the distribution earned for the second quarter of 2017, we will not receive incentive distributions with respect to these common units. We borrowed approximately $14.0 million under our revolving credit facility to fund our general partner contribution to NuStar Energy. Our common limited partner ownership interest in NuStar Energy was approximately 11% subsequent to this issuance. This issuance resulted in a gain of $41.6 million , which is included in “Other income (expense), net” on our consolidated statements of comprehensive income for the year ended December 31, 2017 , calculated as if we had sold a proportionate share of our investment in NuStar Energy.

In 2016, NuStar Energy issued 595,050 common units representing limited partner interests at an average price of $47.39 per unit. NuStar Energy received net proceeds of $28.3 million , which includes our contribution of $0.6 million in order to maintain our 2% general partner interest. This issuance resulted in a gain of $2.1 million for the year ended December 31, 2016 , which is included in “Other income (expense), net” on our consolidated statements of comprehensive income, and represents a gain as if we had sold a proportionate share of our investment in NuStar Energy.

Issuances of Preferred Units. In 2017 and 2016 , NuStar Energy issued fixed-to-floating rate cumulative redeemable perpetual preferred units representing limited partner interests. The preferred units rank senior to all of NuStar Energy’s other classes of equity securities, including our general partner and common limited partner interests, with respect to distribution rights and rights upon liquidation. Distributions on the 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 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 following is a summary of NuStar Energy’s preferred units outstanding as of December 31, 2017 :

Cash Distributions to Unitholders
Our limited liability company agreement requires that, within 50 days after the end of each quarter, we distribute all of our available cash to the holders of record of our units on the applicable record date. Available cash is defined generally as all cash on hand at the end of any calendar quarter, less the amount of cash reserves necessary or appropriate, as determined in good faith by our board of directors, to service debt we may incur, if any, and to fund general and administrative expenses, future distributions and other miscellaneous cash requirements. The following table reflects our cash distributions applicable to the period in which the distributions were earned:

Contingencies
We are not currently a party to any material legal proceedings and have not recorded any accruals for loss contingencies. NuStar Energy is a party to claims and legal proceedings arising in the ordinary course of its business, which it believes are not material to its financial position or results of operations. However, 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 NuStar Energy’s results of operations and ability to pay distributions, which would impact our results of operations and ability to pay distributions.

RELATED PARTY TRANSACTIONS

Agreements with NuStar Energy
Prior to the Employee Transfer, pursuant to a services agreement between NuStar GP, LLC and NuStar Energy, NuStar Energy reimbursed NuStar GP, LLC for furnishing administrative and certain operating services necessary to conduct the business of NuStar Energy. In conjunction with the Employee Transfer, NuStar GP, LLC entered into an Amended and Restated Services Agreement with NuStar Services Co, a wholly owned subsidiary of NuStar Energy, effective March 1, 2016 (the Amended GP Services Agreement). The Amended GP Services Agreement provides that NuStar Services Co will furnish administrative services necessary to conduct our business, for an annual fee of $1.0 million, subject to certain adjustments for merit increases and changes in level of service. The Amended GP Services Agreement will terminate on March 1, 2020 and will automatically renew for successive two-year terms, unless terminated by either party. Please refer to Note 5 of the Notes to Consolidated Financial Statements in Item 8. “Financial Statements and Supplementary Data” for a more detailed discussion of agreements with NuStar Energy.

Following the Merger, we will be a wholly owned subsidiary of NuStar Energy. Please refer to Note 15 of the Notes to Consolidated Financial Statements in Item 8. “Financial Statements and Supplementary Data” for a more detailed discussion of the Merger.

Employee Benefit Plans and Unit-Based Compensation
Prior to the Employee Transfer, we sponsored the following employee benefit and long-term incentive plans, among others:

The NuStar Thrift Plan;
The NuStar Excess Thrift Plan;
The NuStar Pension Plan;
The NuStar Excess Pension Plan;
The NuStar GP, LLC Retiree Welfare Benefits Plan; and
The 2000 Long-Term Incentive Plan.

Prior to the Employee Transfer, NuStar Energy reimbursed NuStar GP, LLC for expenses incurred related to employee benefit plans at cost, and for long-term incentive plan compensation expenses resulting from NS and NSH awards to employees and directors of NuStar GP, LLC.

We continue to sponsor the 2006 Long-Term Incentive Plan, under which NuStar GP Holdings may award up to 2,000,000 (NSH) units, and retain the compensation expense related to these awards.

CRITICAL ACCOUNTING POLICIES

The preparation of financial statements in accordance with U.S. generally accepted accounting principles requires management to select accounting policies and to make estimates and assumptions related thereto that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. The accounting policies below are considered critical due to judgments made by management and the sensitivity of these estimates to deviations of actual results from management’s assumptions. The critical accounting policies should be read in conjunction with Note 2 of the Notes to Consolidated Financial Statements in Item 8. “Financial Statements and Supplementary Data,” which summarizes our significant accounting policies.

Investment in NuStar Energy
We evaluate our investment in NuStar Energy for impairment if and when there is evidence that we may not be able to recover the carrying amount of our investment or that NuStar Energy is unable to sustain an earnings capacity that justifies the carrying amount. If a decline in the value of our investment is determined to be other than temporary, then we would record an impairment loss in the current period based on the difference between the estimated current fair value of the investment and our carrying amount. In order to determine fair value, our management must make certain estimates and assumptions regarding NuStar Energy’s operations, including, among other things, an assessment of market conditions, projected cash flows, interest rates and growth rates that could significantly impact the fair value of our investment. Due to the significant subjectivity of the assumptions used to determine fair value, changes in market conditions and/or changes in assumptions could result in significant impairment charges in the future, thus affecting our earnings. We believe that the carrying amount of our investment in NuStar Energy as of December 31, 2017 is recoverable.

Unit-Based Compensation
Prior to the Employee Transfer, we accounted for awards of NS performance units and restricted units to employees and directors of NuStar GP, LLC and its affiliates at fair value, whereby a liability for the award was initially recorded and subsequent changes in the fair value were included in the determination of net income. The fair value of NS restricted units and performance units equaled the market price of NS common units at each reporting date. However, NS performance units were earned only upon NuStar Energy’s achievement of an objective performance measure. We recorded compensation expense each reporting period such that the cumulative compensation expense equaled the portion of the award’s current fair value that had vested. We recorded compensation expense for NS restricted units and performance units until the date of vesting.

We account for awards of NSH restricted units granted to employees of NuStar GP, LLC and our directors based on the fair value of the awards at the grant date. The fair value of NSH restricted units equals the market price of NSH common units at the grant date. Compensation expense for NSH restricted units is recognized ratably over the vesting period based on the initial fair value determination.

NEW ACCOUNTING PRONOUNCEMENTS

Please refer to Note 3 of the Notes to Consolidated Financial Statements in Item 8. “Financial Statements and Supplementary Data” for a detailed discussion of new accounting pronouncements.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our only cash generating assets are our ownership interests in NuStar Energy, which we account for using the equity method. We have no material market risk other than those market risks affecting NuStar Energy, which could therefore affect the value of our investment. NuStar Energy is exposed to various market risks, including interest rate risk and commodity price risk. For a description of NuStar Energy’s market risks and how it manages its exposure to those risks, please see Item 7A. “Quantitative and Qualitative Disclosures About Market Risk” contained in NuStar Energy’s Form 10-K for the year ended December 31, 2017.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining effective internal control over financial reporting as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934. Our management assessed the effectiveness of NuStar GP Holdings, LLC’s internal control over financial reporting as of December 31, 2017 . In its evaluation, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control – Integrated Framework (2013) . Based on this assessment, management believes that, as of December 31, 2017 , our internal control over financial reporting was effective based on those criteria.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

The effectiveness of internal control over financial reporting as of December 31, 2017 has been audited by KPMG LLP, the independent registered public accounting firm who audited our consolidated financial statements included in this Form 10-K. KPMG LLP’s attestation on the effectiveness of our internal control over financial reporting appears on page 47.

Report of Independent Registered Public Accounting Firm
The Board of Directors and Members
of NuStar GP Holdings, LLC:

Opinion on the Consolidated Financial Statements
We have audited the accompanying consolidated balance sheets of NuStar GP Holdings, LLC and subsidiaries (the “Company”) as of December 31, 2017 and 2016, the related consolidated statements of comprehensive income, members’ equity, and cash flows for each of the years in the three‑year period ended December 31, 2017, and the related notes (collectively, the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the years in the three‑year period ended December 31, 2017, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Company’s internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 28, 2018 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.
Basis for Opinion
These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the Company’s auditor since 2005.

The Board of Directors and Members
of NuStar GP Holdings, LLC:

Opinion on Internal Control Over Financial Reporting
We have audited NuStar GP Holdings, LLC (a Delaware limited partnership) and subsidiaries’ (the “Company”) internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the consolidated balance sheets of the Company as of December 31, 2017 and 2016, the related consolidated statements of comprehensive income, members’ equity, and cash flows for each of the years in the three-year period ended December 31, 2017, and the related notes (collectively, the “consolidated financial statements”), and our report dated February 28, 2018 expressed an unqualified opinion on those consolidated financial statements.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Unless otherwise indicated, the terms “NuStar GP Holdings,” “NSH,” “we,” “our” and “us” are used in this report to refer to NuStar GP Holdings, LLC, to one or more of our consolidated subsidiaries or to all of them taken as a whole.

Our unitholders have no liability under our limited liability company agreement, or for any of our debts, obligations or liabilities, in their capacity as unitholders.

We have no operations or sources of income or cash flows other than our investment in NuStar Energy L.P. (NuStar Energy or NS) (NYSE: NS). As of December 31, 2017 , we have an approximate 13% ownership interest in NuStar Energy, consisting of the following:
the general partner interest;
100% of the incentive distribution rights issued by NuStar Energy, which entitle us to receive increasing percentages of the cash distributed by NuStar Energy, currently at the maximum percentage of 23% ; and
10,214,626 common units of NuStar Energy.

NuStar Energy is a publicly held Delaware limited partnership engaged in the transportation of petroleum products and anhydrous ammonia and the terminalling, storage and marketing of petroleum products. NuStar Energy has pipelines in the United States, as well as terminal and storage facilities in the United States, Canada, Mexico, the Netherlands, including St. Eustatius in the Caribbean, and the United Kingdom. NuStar Energy conducts its operations through its subsidiaries, primarily NuStar Logistics, L.P. (NuStar Logistics) and NuStar Pipeline Operating Partnership L.P.

Recent Developments
Merger. On February 7, 2018, NuStar GP Holdings, NuStar Energy, Riverwalk Logistics, L.P., NuStar GP, LLC, Marshall Merger Sub LLC, a wholly owned subsidiary of NuStar Energy (Merger Sub), and Riverwalk Holdings, LLC entered into an Agreement and Plan of Merger (the Merger Agreement) pursuant to which Merger Sub will merge with and into NuStar GP Holdings with NuStar GP Holdings being the surviving entity (the Merger), such that NuStar Energy will be our sole member following the Merger. Pursuant to the Merger Agreement and at the effective time of the Merger, NuStar Energy’s partnership agreement will be amended and restated to, among other things, (i) cancel the incentive distribution rights, (ii) convert the 2% general partner interest in NuStar Energy into a non-economic management interest and (iii) provide the holders of NuStar Energy’s common units with voting rights in the election of the members of the board of directors of NuStar GP, LLC at an annual meeting, beginning in 2019. The Merger is subject to the satisfaction or waiver of certain conditions, including approval of the Merger Agreement by our unitholders. Please refer to Note 15 for further discussion of the Merger.

NuStar Energy’s Navigator Acquisition and Financing Transactions. On May 4, 2017, NuStar Energy completed the acquisition of Navigator Energy Services, LLC for approximately $1.5 billion (the Navigator Acquisition).

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Consolidation
The accompanying consolidated financial statements include the accounts of NuStar GP Holdings and subsidiaries in which it has a controlling interest. Intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates
The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (GAAP) 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. On an ongoing basis, management reviews its estimates based on currently available information. Management may revise estimates due to changes in facts and circumstances.

Cash and Cash Equivalents
Cash equivalents are all highly liquid investments with an original maturity of three months or less when acquired.
 
Investment in NuStar Energy
We account for our investment in NuStar Energy using the equity method. As the general partner, we exercise significant influence over NuStar Energy. We evaluate our investment in NuStar Energy for impairment when there is evidence that we may not be able to recover the carrying amount of our investment or that the investee is unable to sustain an earnings capacity that justifies the carrying amount. If a decline in the value of our investment is determined to be other than temporary, then we would record an impairment loss in the current period based on the difference between the estimated current fair value of the investment and our carrying amount. We believe that the carrying amount of our investment in NuStar Energy as of December 31, 2017 is recoverable.

Accounting for Issuances of Units by NuStar Energy
We account for issuances of common units by NuStar Energy as if we had sold a proportionate share of our investment, such that we record any gain or loss in earnings.

Income Taxes
We are a limited liability company taxed as a partnership and generally are not subject to federal or state income taxes. Accordingly, our taxable income or loss, which may vary substantially from income or loss reported for financial reporting purposes, is generally included in the federal and state income tax returns of our unitholders. For transfers of publicly held units subsequent to our initial public offering, we have made an election permitted by Section 754 of the Internal Revenue Code (the Code) to adjust the common unit purchaser’s tax basis in our underlying assets to reflect the purchase price of the units. This results in an allocation of taxable income and expenses to the purchaser of the common units, including depreciation deductions and gains and losses on sales of assets, based upon the new unitholder’s purchase price for the common units.

On August 14, 2006, NuStar GP, LLC, our wholly owned subsidiary, elected to be treated as a corporation for federal income tax purposes under Treasury Regulation §301.7701-3(a). We account for income taxes under the asset and liability method. Under this method, we recognize deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. We measure deferred taxes using enacted tax rates expected to apply to taxable income in the year those temporary differences are expected to be recovered or settled.

Income tax expense includes federal and state income and withholding taxes currently payable and deferred federal and state income taxes resulting from temporary differences between financial statement and tax bases of assets and liabilities when such differences exist. We, or certain of our subsidiaries, file income tax returns in the U.S. federal jurisdiction and various state jurisdictions. For U.S. federal and state purposes, tax years subject to examination are 2013 through 2016, according to standard statutes of limitations .

We recognize a tax position if it is more likely than not that the tax position will be sustained, based on the technical merits of the position, upon examination. We record uncertain tax positions in the financial statements at the largest amount of benefit that is more likely than not to be realized. We had no unrecognized tax benefits as of December 31, 2017 and 2016 .

53

NUSTAR GP HOLDINGS, LLC
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

Net Income Per Common Unit
Net income per common unit is determined pursuant to the two-class method. Under this method, all earnings are allocated to our common units and participating securities based on their respective rights to receive distributions earned during the period. Participating securities include restricted units awarded under our long-term incentive plan. Net income attributable to distribution equivalent rights for outstanding restricted units totaled $0.2 million for the years ending December 31, 2017 and 2016. We compute net income per common unit by dividing net income attributable to our common units by the weighted-average number of common units outstanding during the period. Basic and diluted net income per common unit are the same as we have no potentially dilutive securities outstanding.

Unit-Based Compensation
We account for awards of NSH restricted units granted to employees of NuStar GP, LLC and our directors based on the fair value of the awards at the grant date. Compensation expense for NSH restricted units is recognized ratably over the vesting period based on the initial fair value determination, and is included in “General and administrative expenses” on our consolidated statements of comprehensive income.

Prior to the Employee Transfer, we accounted for awards of NS performance units and restricted units to employees and directors of NuStar GP, LLC and its affiliates at fair value, whereby a liability for the award was initially recorded and subsequent changes in the fair value were included in the determination of net income. The fair value of NS restricted units and performance units equaled the market price of NS common units at each reporting date. However, NS performance units were earned only upon NuStar Energy’s achievement of an objective performance measure. We recorded compensation expense each reporting period such that the cumulative compensation expense equaled the portion of the award’s current fair value that had vested. We recorded compensation expense related to NS restricted units and performance units until the date of vesting. Prior to the Employee Transfer, we recorded a liability on our consolidated balance sheet for awards of NS performance units and restricted units and NuStar Energy reimbursed us for the expenses resulting from NS awards and NSH awards to employees providing services to NuStar Energy. Following the Employee Transfer, NuStar Energy retains the expenses resulting from NS awards and we retain the expenses resulting from NSH awards.

Distribution Equivalent Rights (DERs) paid with respect to outstanding, unvested NS units were expensed, whereas DERs with respect to outstanding, unvested NSH restricted units reduce equity, similar to cash distributions to unitholders. Forfeitures of our unit-based awards are recognized as an adjustment to compensation expense when they occur.

3. NEW ACCOUNTING PRONOUNCEMENTS

Unit-Based Payments
In May 2017, the Financial Accounting Standards Board (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. Under 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 adopted these provisions January 1, 2018, and they did not have a material impact on our financial position, results of operations or disclosures.

Statement of Cash Flows
In August 2016, the FASB issued amended guidance that clarifies how entities should present certain cash receipts and cash payments on the statement of cash flows, including but not limited to debt prepayment or debt extinguishment costs; contingent consideration payments made after a business combination; proceeds from the settlement of insurance claims and distributions received from equity method investees. The changes are effective for annual and interim periods beginning after December 15, 2017, and amendments should be applied retrospectively. We adopted these provisions January 1, 2018, and they did not have an impact on our statements of cash flows or disclosures.

Financial Instruments
In January 2016, the FASB issued new guidance that addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments. The changes are effective for annual and interim periods beginning after December 15, 2017, and amendments should be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. We adopted these provisions January 1, 2018, and they did not have a material impact on our financial position, results of operations or disclosures.


54

NUSTAR GP HOLDINGS, LLC
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

Deferred Taxes
In November 2015, the FASB issued amended guidance that requires deferred tax assets and liabilities to be classified as noncurrent on the balance sheet. The changes are effective for annual and interim periods beginning after December 15, 2016, using either a prospective or retrospective transition method, and early adoption is permitted. We adopted these provisions on a prospective basis on January 1, 2017, and they did not have an impact on our financial position, results of operations or disclosures.

4. INVESTMENT IN NUSTAR ENERGY

NuStar Energy’s Acquisitions
Navigator Acquisition. On April 11, 2017, NuStar Logistics and NuStar Energy 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 . NuStar Energy closed the Navigator Acquisition on May 4, 2017 and funded the purchase price with the net proceeds of the equity and debt issuances described below. NuStar Energy 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.

The Navigator Acquisition broadens NuStar Energy’s geographic footprint by marking its entry into the Permian Basin and complements its existing asset base. NuStar Energy believes this acquisition provides a strong growth platform that, when coupled with its assets in the Eagle Ford region, solidifies its presence in two of the most prolific basins in the United States.

We amended and restated NuStar Energy’s partnership agreement in connection with NuStar Energy’s issuance of the Series B Preferred Units described below and the Navigator Acquisition to waive up to an aggregate $22.0 million of the quarterly incentive distributions payable to us 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 second quarter of 2017.

Martin Terminal Acquisition. On December 21, 2016, NuStar Energy acquired crude oil and refined product storage assets in Corpus Christi, TX for $95.7 million , including $2.1 million of capital expenditure reimbursements, from Martin Operating Partnership L.P. (the Martin Terminal Acquisition). The assets acquired include 900,000 barrels of crude oil storage capacity, 250,000 barrels of refined product storage capacity and exclusive use of the Port of Corpus Christi’s new crude oil dock.

Linden Acquisition . On January 2, 2015, NuStar Energy acquired full ownership of a refined products terminal in Linden, NJ for $142.5 million (the Linden Acquisition). Prior to the Linden Acquisition, the terminal operated as a joint venture between NuStar Energy and Linden Holding Corp, with each party owning 50% .

NuStar Energy’s Equity Issuances
Issuances of Common Units. On April 18, 2017, NuStar Energy issued 14,375,000 common units representing limited partner interests at a price of $46.35 per unit. NuStar Energy used the net proceeds from this offering of $657.5 million , including our contribution of $13.6 million to maintain our 2% general partner interest, to fund a portion of the purchase price for the Navigator Acquisition. Beginning with the distribution earned for the second quarter of 2017, we will not receive incentive distributions with respect to these common units. We borrowed approximately $14.0 million under our revolving credit facility to fund our general partner contribution to NuStar Energy, and our common limited partner ownership interest in NuStar Energy was approximately 11% subsequent to this issuance. This issuance resulted in a gain of $41.6 million , which is included in “Other income (expense), net” on our consolidated statements of comprehensive income for the year ended December 31, 2017 , calculated as if we had sold a proportionate share of our investment in NuStar Energy.

In 2016, NuStar Energy issued 595,050 common units representing limited partner interests at an average price of $47.39 per unit. NuStar Energy received net proceeds of $28.3 million , which includes our contribution of $0.6 million in order to maintain our 2% general partner interest. This issuance resulted in a gain of $2.1 million for the year ended December 31, 2016 , which is included in “Other income (expense), net” on our consolidated statements of comprehensive income, calculated as if we had sold a proportionate share of our investment in NuStar Energy.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)


Issuances of Preferred Units. In 2017 and 2016, NuStar Energy issued fixed-to-floating rate cumulative redeemable perpetual preferred units representing limited partner interests. The preferred units rank senior to all of NuStar Energy’s other classes of equity securities, including our general partner and common limited partner interests, with respect to distribution rights and rights upon liquidation. Distributions on the 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 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.

We do not own any NuStar Energy preferred limited partner units. Accordingly, we subtract NuStar Energy’s preferred limited partners’ equity from its total equity and apply our ownership percentage of NuStar Energy’s remaining equity when reconciling to our investment in NuStar Energy above.

Valero Energy Corporation (Valero Energy) acquired us in connection with its December 31, 2001 acquisition of Ultramar Diamond Shamrock Corporation (2001 Acquisition). The step-up in basis related to NuStar Energy’s assets and liabilities, including equity method goodwill, reflected in the table above relates to purchase accounting adjustments resulting from the 2001 Acquisition. The amount represents the unamortized excess of the fair value over carrying amount applicable to Valero Energy’s proportionate 73.6% interest in NuStar Energy’s identifiable assets and liabilities as of December 31, 2001, of which $81.8 million is being amortized as a reduction to equity in earnings of NuStar Energy over approximately 28 years. This amount also includes the portion of goodwill resulting from the 2001 Acquisition that was attributed to our investment in NuStar Energy. Since 26.4% of the equity interest in NuStar Energy was owned by public unitholders as of the date of the 2001 Acquisition, a significant portion of the total ownership interest in NuStar Energy was deemed to be held by the public according to GAAP, thereby preventing the adjustment of the reported financial statements of NuStar Energy.

GP Services Agreement. Prior to the Employee Transfer, NuStar GP, LLC performed services for NuStar Energy’s U.S. operations. Employees of NuStar GP, LLC provided services to both NuStar Energy and NuStar GP Holdings; therefore, NuStar Energy reimbursed NuStar GP, LLC for all employee costs incurred prior to the Employee Transfer, other than the expenses allocated specifically to NuStar GP Holdings (the Holdco Administrative Services Expense). For the years ended December 31, 2016 and 2015, the Holdco Administrative Services Expense totaled $0.2 million and $1.5 million , respectively.

The Amended GP Services Agreement will terminate on March 1, 2020 and will automatically renew for successive two-year terms, unless terminated by either party.

As shown in the table above, we transferred to NuStar Services Co $32.7 million in benefit obligations associated with the Pension Plans and other postretirement benefit plans, which were primarily reported in “Long-term liabilities” on our consolidated balance sheet prior to the Employee Transfer. Additionally, we transferred an accumulated other comprehensive income balance related to the unrecognized components of net periodic benefit cost (income) of $4.2 million . We also transferred to NuStar Services Co all outstanding awards under the Fifth Amended and Restated 2000 Long-Term Incentive Plan, which represented 730,288 units, and removed the obligation related to these unit-based awards, which was previously reported as “Current liabilities,” from our consolidated balance sheet.

Balance Sheet Items . We had a payable to NuStar Energy of $0.2 million and $0.3 million as of December 31, 2017 and 2016 , respectively, mainly comprised of service fees and expenses paid on behalf of NuStar GP Holdings.

Non-Compete Agreement. On July 19, 2006, in connection with our initial public offering, we entered into a non-compete agreement with NuStar Energy (the Non-Compete Agreement). Under the Non-Compete Agreement, we will have a right of first refusal with respect to the potential acquisition of general partner and other equity interests in publicly traded partnerships under common ownership with the general partner interest. NuStar Energy has a right of first refusal with respect to the potential acquisition of assets that relate to the transportation, storage or terminalling of crude oil, feedstocks or refined petroleum products (including petrochemicals) in the United States and internationally. With respect to any other business opportunities, neither we nor NuStar Energy are prohibited from engaging in any business, even if we and NuStar Energy would have a conflict of interest with respect to such other business opportunity. The Non-Compete Agreement remains in effect for so long as we or any of our affiliates own 20% or more of NuStar GP, LLC or Riverwalk Logistics, L.P.

6. DISTRIBUTIONS FROM NUSTAR ENERGY

NuStar Energy’s partnership agreement, determines the amount and priority of cash distributions that NuStar Energy’s unitholders and general partner may receive. We, as NuStar Energy’s general partner, are entitled to incentive distributions if the amount NuStar Energy distributes with respect to any quarter exceeds $0.60 per common unit, with the maximum percentage of 23% of the amount of any quarterly distribution in excess of $0.66 per common unit. We also receive a 2% distribution with respect to our general partner interest. The following table reflects the allocation of NuStar Energy’s cash distributions earned for the periods indicated among its general partner and common limited partners:

7. 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 recognize cash equivalents, receivables, payables and short-term debt in our consolidated balance sheets at their carrying amounts. The fair values of these financial instruments approximate their carrying amounts. The fair value measurement of our short-term debt would fall in Level 2 of the fair value hierarchy.

Non-cash investing and financing activities mainly consisted of:
Adjustments to our investment in NuStar Energy and accumulated other comprehensive income (loss) through recognition of our proportionate share of NuStar Energy’s accumulated other comprehensive income (loss); and
Prior to the Employee Transfer, pension funding adjustments recognized in accumulated other comprehensive income (loss).

9. CREDIT FACILITY

Our revolving credit facility dated June 28, 2013 currently has a borrowing capacity of up to $60.0 million , of which up to $10.0 million may be available for letters of credit. We amended this facility on June 27, 2017 to, among other things, extend its maturity to June 27, 2018 and increase its borrowing capacity from $50.0 million to $60.0 million . Our obligations under our revolving credit facility are guaranteed by Riverwalk Holdings, LLC (Riverwalk), our wholly owned subsidiary. Riverwalk has pledged a total of 2,926,833 NuStar Energy common units that it owns to secure its guarantee. Borrowings under our revolving credit facility are used to fund capital contributions to NuStar Energy, to maintain our 2% general partner interest when NuStar Energy issues additional common units and to meet other liquidity and capital resource requirements.

As of December 31, 2017 , we had outstanding borrowings of $42.5 million and availability of $17.5 million for borrowings under our revolving credit facility. Interest on our revolving credit facility is based upon, at our option, either an alternative base rate or a LIBOR-based rate . The weighted-average interest rates related to borrowings under our revolving credit facility as of December 31, 2017 and 2016 were 3.6% and 2.8% , respectively. As of December 31, 2017 and 2016 , unamortized

NUSTAR GP HOLDINGS, LLC
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

deferred debt costs associated with our revolving credit agreement totaled $ 0.1 million and are included in “Prepaid expenses and other current assets” on our consolidated balance sheets.

The revolving credit facility contains customary restrictive covenants, such as limitations on indebtedness, liens, dispositions of material property, mergers, asset transfers and certain investing activities. In addition, the revolving credit facility requires NuStar Energy to comply with the financial covenant contained in NuStar Logistics revolving credit facility. We are also required to receive cash distributions each fiscal quarter of at least $19.0 million in respect of our ownership interests in NuStar Energy. Our management believes that we are in compliance with the covenants of our revolving credit facility as of December 31, 2017 .

10. COMMITMENTS AND CONTINGENCIES

Contingencies
We are not currently a party to any material legal proceedings and have not recorded any accruals for loss contingencies. NuStar Energy is a party to claims and legal proceedings arising in the ordinary course of its business, which it believes are not material to its financial position or results of operations. However, 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 NuStar Energy’s results of operations and ability to pay distributions, which would impact our results of operations and ability to pay distributions.

Commitments
As of December 31, 2017 , we had no future minimum payments applicable to non-cancellable operating leases and purchase obligations.

Rights Agreement
On July 19, 2006, we entered into a rights agreement, as amended (the Rights Agreement), under which one preferred unit purchase right (a Right) was attached to each of our outstanding units. The Rights became exercisable under specified circumstances, including if any person or group (an acquiring person) became the beneficial owner of 15% or more of our outstanding units, subject to specified exceptions. The Rights Agreement and the Rights expired on June 30, 2016.

12. UNIT-BASED COMPENSATION

2006 LTIP
We sponsor the 2006 Long-Term Incentive Plan (the LTI Plan) under which NuStar GP Holdings may award up to 2,000,000 NSH units to our employees, consultants and directors who perform services for us or our affiliates. Awards under the LTI Plan can include NSH unit options, performance units, distribution equivalent rights (DERs), restricted units, phantom units, unit grants and unit appreciation rights. As of December 31, 2017 , a total of 1,391,259 NSH units remained available to be awarded under the LTI Plan. Effective on the date of the Employee Transfer and the Assignment Agreement, we retain the expense associated with awards granted under the LTI Plan to our employees, whereas these expenses were previously reimbursed by NuStar Energy.

2000 LTIP
Prior to the Employee Transfer, we sponsored the Long-Term Incentive Plan (the 2000 LTIP), under which NuStar GP, LLC could award up to 3,250,000 NS common units, and NuStar Energy reimbursed NuStar GP, LLC for all employee costs, including unit-based compensation costs. Awards under the 2000 LTIP could include NS unit options, restricted units, performance units, DERs and contractual rights to receive common units.

On March 1, 2016, in conjunction with the Employee Transfer, we transferred to NuStar Services Co all outstanding awards under the 2000 LTIP, which totaled 730,288 units, including 77,014 performance units, and removed the obligation related to these unit-based awards from our consolidated balance sheet. However, of the performance units transferred, only 35,373 were considered granted for accounting purposes, as the performance measure for the remaining units had not yet been set.

13. INCOME TAXES

On December 22, 2017, the U.S. enacted the Tax Cuts and Jobs Act (“the Act”). The Act, which is also commonly referred to as “U.S. tax reform,” significantly changes U.S. corporate income tax laws by, among other things, reducing the U.S. corporate tax rate from 35% to 21% starting in 2018. As a result, we recorded an expense of $2.0 million in the fourth quarter of 2017, which is included “Income tax (expense) benefit” in the consolidated statements of comprehensive income. The expense results from the revaluation of our net deferred tax assets based on the new lower corporate income tax rate. Our accounting for the corporate tax rate reduction is complete. The Act is expected to have minimal impact to future years.

Components of income tax (expense) benefit were as follows:

The difference between income tax expense recorded in our consolidated statements of income and income taxes computed by applying the statutory federal income tax rate ( 35% for all years presented) to income before income tax expense is due to the fact that the majority of our income is not subject to federal income tax based on our status as a limited liability company.

As of December 31, 2017 , our U.S. corporate operations have net operating loss carryforwards and capital loss carryforwards for tax purposes totaling approximately $14.9 million and $3.8 million , respectively, which are subject to a twenty-year and a five-year carryforward limitation , respectively, and begin to expire in 2031 and 2018 , respectively.

As of December 31, 2017 and 2016 , we have a valuation allowance of $0.9 million and $1.4 million , respectively, related to our deferred tax assets. We estimate the amount of valuation allowance based upon our expectations of taxable income and the period over which we can utilize those future deductions. The valuation allowance reflects uncertainties related to our ability to utilize certain capital loss carryforwards and foreign tax credits before they expire.

The realization of deferred income tax assets recorded as of December 31, 2017 is dependent upon our ability to generate future taxable income in the United States. We believe it is more likely than not that the deferred income tax assets as of December 31, 2017 will be realized, based upon expected future taxable income and potential tax planning strategies.

NUSTAR GP HOLDINGS, LLC
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

15. SUBSEQUENT EVENT
On February 7, 2018, NuStar GP Holdings, NuStar Energy, Riverwalk Logistics, L.P., NuStar GP, LLC, Marshall Merger Sub LLC, a wholly owned subsidiary of NuStar Energy (Merger Sub), and Riverwalk Holdings, LLC entered into an Agreement and Plan of Merger (the Merger Agreement) pursuant to which Merger Sub will merge with and into NuStar GP Holdings with NuStar GP Holdings being the surviving entity (the Merger), such that NuStar Energy will be our sole member following the Merger. Pursuant to the Merger Agreement and at the effective time of the Merger, NuStar Energy’s partnership agreement will be amended and restated to, among other things, (i) cancel the incentive distribution rights, (ii) convert the 2% general partner interest in NuStar Energy into a non-economic management interest and (iii) provide the holders of NuStar Energy’s common units with voting rights in the election of the members of the board of directors of NuStar GP, LLC at an annual meeting, beginning in 2019.
At the effective time of the Merger, each of our outstanding common units will be converted into the right to receive 0.55 of a NuStar Energy common unit. All of our common units, when converted, will cease to be outstanding and will automatically be cancelled and no longer exist. No fractional NuStar Energy common units will be issued in the Merger; instead, each holder of our common units otherwise entitled to receive a fractional NuStar Energy common unit will receive cash in lieu thereof. Furthermore, the 10,214,626 NuStar Energy common units currently owned by us will be cancelled and will cease to exist.
At the effective time of the Merger, each outstanding award of NuStar GP Holdings restricted units will be converted, on the same terms and conditions as were applicable to the awards immediately prior to the Merger, into an award of NuStar Energy restricted units. The number of NuStar Energy restricted units subject to the converted awards will be determined as provided in the Merger Agreement. Each of our executive officers and directors has agreed and acknowledged that the Merger will not be deemed to trigger a “change of control” as defined under the NuStar GP Holdings plan or award, and has waived any rights to vesting, payment or other benefit thereunder that would arise upon a “change of control,” to which he or she might otherwise have been entitled.

The Merger Agreement contains customary representations and warranties and covenants by each of the parties. Completion of the Merger is conditioned upon, among other things: (i) approval of the Merger Agreement by the affirmative vote of holders of a Unit Majority, as defined in the Second Amended and Restated Limited Liability Company Agreement of NuStar GP Holdings, as amended; (ii) the effectiveness of a registration statement on Form S-4 with respect to the issuance by NuStar Energy of its common units in connection with the Merger; (iii) the absence of certain legal injunctions or impediments prohibiting the transactions; (iv) the receipt of certain tax opinions from a nationally recognized tax counsel; and (v) the approval for the listing of NuStar Energy’s common units to be issued in the Merger on the New York Stock Exchange.

NuStar Energy entered into a Support Agreement, dated as of February 7, 2018 (the Support Agreement), with Merger Sub, WLG Holdings, LLC, a Texas limited liability company (WLG Holdings), Mr. Greehey (together, WLG Holdings and Mr. Greehey are referred to as the Greehey Unitholders), and, for limited purposes, us, pursuant to which the Greehey Unitholders have agreed to vote in favor of the approval and adoption of the Merger Agreement, the approval of the Merger and any other action required in furtherance thereof submitted for the vote or written consent of our unitholders. The Greehey Unitholders collectively own approximately 21% of our outstanding units. The Support Agreement will terminate (i) at the effective time of the Merger, (ii) upon the termination of the Merger Agreement, or (iii) at such time as NuStar Energy and the Greehey Unitholders agree in writing to terminate the Support Agreement.
After the Merger, the NuStar GP, LLC board of directors is expected to consist of nine members, initially composed of the six members of the NuStar GP, LLC board of directors and the three independent directors of the board of directors of NuStar GP Holdings.

Additionally, on February 8, 2018, NuStar Energy announced that NuStar Energy’s management anticipates recommending to the board of directors of NuStar GP, LLC, and expects such board of directors to adopt, a reset of NuStar Energy’s quarterly distribution per common unit to $0.60 ( $2.40 on an annualized basis), starting with the first-quarter distribution payable in May 2018. We expect to adjust the quarterly distribution to our members accordingly.

The Nominating/Governance Committee strives to find the best possible candidates to represent the interests of NuStar GP Holdings and its unitholders. As part of its annual self-assessment process, the Nominating/Governance Committee annually evaluates the mix of independent and non-independent directors, the selection and functions of the presiding director and whether the Board has the appropriate range of talents, expertise and backgrounds.

CORPORATE GOVERNANCE

AUDIT COMMITTEE

The Audit Committee reviews and reports to the Board on various auditing and accounting matters, including the quality, objectivity and performance of our internal and external accountants and auditors, the adequacy of our financial controls and the reliability of financial information reported to the public. The Audit Committee also monitors our efforts to comply with environmental laws and regulations. The Board has adopted a written charter for the Audit Committee, a copy of which is available on our website at www.nustargpholdings.com. The members of the Audit Committee are Mr. Burnett (Chairman), Mr. Clingman and Ms. LeBlanc-Burley.

The Audit Committee met eight times during 2017. For further information, see the Audit Committee Report below.

AUDIT COMMITTEE REPORT

Management is responsible for NuStar GP Holdings’ internal controls and the financial reporting process. KPMG, NuStar GP Holdings’ independent registered public accounting firm for the year ended December 31, 2017, is responsible for performing an independent audit of NuStar GP Holdings’ consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (PCAOB), and an audit of NuStar GP Holdings’ internal control over financial reporting in accordance with the standards of the PCAOB, and issuing a report thereon. The Audit Committee monitors and oversees these processes and approves the selection and appointment of NuStar GP Holdings’ independent registered public accounting firm and recommends the ratification of such selection and appointment to the Board.

The Audit Committee has reviewed and discussed NuStar GP Holdings’ audited financial statements with management and KPMG. The Audit Committee has discussed with KPMG the matters required to be discussed by Auditing Standard 1301, “ Communications with Audit Committees, ” issued by the PCAOB. The Audit Committee has received written disclosures and the letter from KPMG required by applicable requirements of the PCAOB concerning independence, and has discussed with KPMG its independence.

Based on the foregoing review and discussions and such other matters the Audit Committee deemed relevant and appropriate, the Audit Committee recommended to the Board that the audited financial statements of NuStar GP Holdings be included in NuStar GP Holdings’ Annual Report on Form 10-K for the year ended December 31, 2017.

The Audit Committee assists the Board in oversight of the integrity of NuStar GP Holdings’ financial statements and NuStar GP Holdings’ compliance with legal and regulatory requirements, including those related to the health, safety and environmental performance of our company.

The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis with management.

Members of the Compensation Committee:

James F. Clingman, Jr. (Chairman)
William B. Burnett

COMPENSATION DISCUSSION AND ANALYSIS

Our only cash-generating asset is our indirect ownership interest in NuStar Energy, a publicly traded Delaware limited partnership (NYSE: NS). Our wholly owned subsidiary, NuStar GP, LLC, is the general partner of the general partner of NuStar Energy. Our officers also serve as officers of NuStar GP, LLC and subsidiaries of NuStar Energy, including NuStar Services Co, which, as described below, currently provides all management and administrative services to us. Our officers are employees of both NuStar GP, LLC and NuStar Services Co.

SERVICES AGREEMENT

We historically have not paid our officers. Instead, under a services agreement in effect until March 1, 2016 (the Services Agreement), we received administrative services, which included executive management, accounting, legal, cash management, corporate finance and other services, from NuStar GP, LLC for an administrative services fee. In addition to the administrative services fee, we historically have paid 1% of NuStar GP, LLC’s domestic bonus and unit compensation expense, subject to certain adjustments.

On March 1, 2016, NuStar GP, LLC transferred and assigned to NuStar Services Co, a wholly owned subsidiary of NuStar Energy, employment of all of NuStar GP, LLC’s employees. In connection with the transfer and assignment, we amended and restated the Services Agreement (the Amended and Restated Services Agreement) such that, beginning March 1, 2016, we receive all management and administrative services from NuStar Services Co. We pay NuStar Services Co an administrative services fee of $1.0 million per year, subject to adjustment (1) by an annual amount equal to NuStar Services Co’s annual merit increase percentage for the most recently completed fiscal year and (2) for changed levels of services due to expansion of operations through acquisitions, construction of new businesses or assets or otherwise. For 2017, the administrative services fee was approximately $900,000. Beginning March 1, 2016, we no longer pay 1% of NuStar GP, LLC’s domestic bonus and unit compensation expense. Instead, we retain the expense associated with our common unit awards and any other compensation that we may provide to our officers.

Table of Contents

EXECUTIVE COMPENSATION

Our named executive officers (NEOs) for the year ended December 31, 2017 were:

Bradley C. Barron, President and Chief Executive Officer;
Thomas R. Shoaf, Executive Vice President and Chief Financial Officer;
Mary Rose Brown, Executive Vice President and Chief Administrative Officer;
Daniel S. Oliver, Senior Vice President-Marketing and Business Development; and
Michael Truby, Senior Vice President-Operations.

Our NEOs also are the NEOs of NuStar GP, LLC and officers of subsidiaries of NuStar Energy. All of our NEOs are compensated by NuStar Energy through its subsidiary, NuStar Services Co. The compensation committee of the board of directors of NuStar GP, LLC (the NS Compensation Committee) establishes the compensation paid to our NEOs for their services as officers of NuStar GP, LLC and subsidiaries of NuStar Energy, which is disclosed in NuStar Energy’s Annual Report on Form 10-K for the year ended December 31, 2017 (the NS 2017 Form 10-K).

We pay an administrative services fee to NuStar Services Co for all management and administrative services, as described above. Beginning March 1, 2016, we also retain the expense associated with awards of our common units. No portion of the administrative services fee paid to NuStar Services Co is allocated for the compensation of our NEOs. The only compensation that we provide to our NEOs is an annual award of “phantom” units (which we refer to as “restricted units” in Part III of this Annual Report) under our Long-Term Incentive Plan, as amended and restated as of April 1, 2007 (the LTI Plan). Our performance is directly tied to the performance of NuStar Energy since our sole cash-generating asset is our indirect ownership interest in NuStar Energy. Accordingly, we provide an annual award of our restricted units to our NEOs to tie a portion of our NEOs’ overall financial reward opportunities with the rewards to our unitholders, as measured by our long-term common unit price performance. We believe that the grants of our restricted units encourage our NEOs to continue to devote their best efforts to advancing our business and the business of NuStar Energy.

As described in the NS 2017 Form 10-K, the NS Compensation Committee annually considers the aggregate compensation payable to each NEO, as well as the form of compensation. In consultation with NuStar Energy’s Human Resources department and Energy Partners Pay Advisors (EPPA), the Chief Executive Officer develops recommendations for the compensation of the other NEOs for consideration by the NS Compensation Committee. Each of the NS Compensation Committee and our Compensation Committee retained EPPA as independent compensation consultant for guidance with respect to executive compensation matters and determined that there are no conflicts of interest with EPPA.

The NS Compensation Committee designates a target long-term incentive award opportunity for each NEO expressed as a percentage of each NEO’s base salary established by the NS Compensation Committee. Approximately 65% of each NEO’s total long-term incentive target is provided through restricted unit awards, with 30% of the target restricted unit value provided through awards of our restricted units by our Compensation Committee and 70% of the target restricted unit value provided through awards of NuStar Energy restricted units by the NS Compensation Committee.

On October 18, 2017, our Compensation Committee approved restricted unit grants to our NEOs and determined that the restricted unit grants would be made as soon as administratively practicable and no earlier than the third business day following our third quarter earnings release. Due to the time required to award and implement the grants, the 2017 annual grants were not effective until November 16, 2017. The following table sets forth the restricted units granted to each NEO by our Compensation Committee in 2017.

No units are issued at the time of grant and our restricted units represent the right to receive common units upon vesting. The awards are calculated from an assumed unit value based on the average closing price of our common units for the first 10 business days of the month prior to the Compensation Committee meeting at which the awards are to be approved. For more information regarding our 2017 restricted unit grants, see the table entitled “Grants of Plan-Based Awards During the Year Ended December 31, 2017.”

In April 2017, we held a unitholder advisory vote on the compensation of our NEOs. More than 88% of the votes cast on the matter approved the compensation of our NEOs as disclosed in our 2017 proxy statement, and our executive compensation program and policies have not changed substantively since that time. We currently hold our say-on-pay advisory vote once every three years.

Accounting Treatment

We account for awards of our restricted units granted under the LTI Plan at fair value.  We use the market price at the grant date as the fair value of restricted units. We recognize the resulting compensation expense ratably over the vesting period.

Tax Treatment

We are a limited liability company. We are treated as a partnership and not a corporation for U.S. federal income tax purposes. Therefore, we are not subject to the executive compensation deduction limitations under Section 162(m) of the Internal Revenue Code of 1986, as amended (the Code).

COMPENSATION-RELATED POLICIES

Unit Ownership Guidelines

As mentioned above, our only cash-generating asset is our indirect ownership interest in NuStar Energy and, as such, our performance is directly tied to the performance of NuStar Energy. We believe that ownership of our common units and NuStar Energy units aligns the interests of our directors and executives with those of our unitholders. We have long emphasized and reinforced the importance of unit ownership among our executives and directors. Our unit ownership and retention guidelines are described below.

Non-Employee Director Unit Ownership Guidelines
Non-employee directors are expected to acquire and hold during their service as a Board member NuStar GP Holdings common units and/or NuStar Energy units with an aggregate value of at least two times their annual cash retainer. Directors have five years from their initial election to the Board to meet the target unit ownership guidelines, and they are expected to continuously own sufficient units to meet the guidelines, once attained. As of December 31, 2017, each of our directors exceeded the ownership levels set forth in the unit ownership guidelines.

Officer Unit Ownership Guidelines
Unit ownership guidelines for the officers set forth below are as follows:

Officer
Value of NuStar GP Holdings Common Units and/or NuStar Energy Units Owned
CEO/President
4.0x base salary
 
EVP serving on CEO’s officer committee
3.0x base salary
 
SVP serving on CEO’s officer committee
2.0x base salary
 
VP serving on CEO’s officer committee
1.0x base salary
 

The officers subject to the unit ownership and retention guidelines, including each of our NEOs, are expected to meet the applicable guidelines within five years of becoming subject to the guidelines and continuously own sufficient units to meet the guidelines, once attained. As of December 31, 2017, each of our NEOs exceeded the ownership levels set forth in the unit ownership guidelines.


75

Table of Contents

Unit Ownership
For purposes of satisfying the unit ownership guidelines, the following units are considered owned:

units owned directly;
units owned indirectly through possession of the right to sell, transfer and/or vote such units; and
unvested restricted or phantom units granted under our LTI Plan or NuStar GP, LLC’s long-term incentive plan.

Unexercised unit options and unvested performance units are not considered owned for purposes of satisfying the unit ownership guidelines.

Prohibition on Insider Trading and Speculation in NuStar GP Holdings or NuStar Energy Units

We have established policies prohibiting our officers, directors and employees from purchasing or selling either NuStar GP Holdings or NuStar Energy securities while in possession of material, nonpublic information or otherwise using such information for their personal benefit or in any manner that would violate applicable laws and regulations. Directors, officers and certain other employees are prohibited from trading in either NuStar GP Holdings or NuStar Energy securities for the period beginning on the last business day of each calendar quarter through the first business day following our disclosure of our quarterly or annual financial results. In addition, our policies prohibit officers, directors and employees from speculating in either NuStar GP Holdings or NuStar Energy units, such as by short selling (profiting if the market price of our units decreases), buying or selling publicly traded options (including writing covered calls), hedging or any other type of derivative arrangement that has a similar economic effect. Directors, officers and certain other employees also are required to obtain consent from the Chief Executive Officer (or, in the case of the Chief Executive Officer, from the Chair of the applicable company’s Audit Committee) before they enter into margin loans or other financing arrangements that may lead to the ownership or other rights to their NuStar GP Holdings or NuStar Energy securities being transferred to a third party.

EVALUATION OF COMPENSATION RISK

Historically, pursuant to a services agreement between our subsidiary, NuStar GP, LLC, and NuStar Energy, as described above in “Compensation Discussion and Analysis,” NuStar GP, LLC employees performed our management and administrative services, for which we paid an annual services fee and 1% of NuStar GP, LLC’s domestic bonus and unit compensation expense. On March 1, 2016, NuStar GP, LLC transferred and assigned to NuStar Services Co, a wholly owned subsidiary of NuStar Energy, employment of all of NuStar GP, LLC’s employees. In connection with the transfer and assignment, NuStar GP Holdings, NuStar GP, LLC, NuStar Energy and NuStar Services Co amended and restated the services agreement such that, beginning March 1, 2016, we receive all management and administrative services from NuStar Services Co. We pay NuStar Services Co an administrative services fee of $1.0 million per year, subject to certain adjustments, but we no longer pay 1% of NuStar GP, LLC’s domestic bonus and unit compensation expense. Instead, we retain the expense associated with our common unit awards and any other compensation that we may provide to our officers.

Although we have officers, we historically have not paid their compensation, other than through the fees paid under the services agreement. The administrative services fee for 2017 was approximately $900,000. We believe that our common unit awards and the administrative services fee that we pay do not create incentives to take risks that are reasonably likely to have a material adverse effect on NuStar GP Holdings.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

There are no compensation committee interlocks. The members of our Compensation Committee are Mr. Clingman (Chairman) and Mr. Burnett. None of the members of the Compensation Committee have served as an officer or employee of ours. Furthermore, except for compensation arrangements disclosed in this Annual Report on Form 10-K, NuStar GP Holdings has not participated in any contracts, loans, fees or awards, nor does it have financial interests, direct or indirect, with any Compensation Committee member. In addition, none of our management or Board members are aware of any means, directly or indirectly, by which a Compensation Committee member could receive a material benefit from NuStar GP Holdings.

Table of Contents

COMPENSATION OF EXECUTIVE OFFICERS AND DIRECTORS

As described above in “Compensation Discussion and Analysis,” all of our officers are compensated by NuStar Energy and NuStar Services Co and, under the Amended and Restated Services Agreement, we pay NuStar Services Co an administrative services fee. No portion of the administrative services fee paid to NuStar Services Co is allocated for the compensation of our NEOs. The NuStar GP Holdings restricted units are the only compensation that we currently provide to our NEOs. Prior to March 1, 2016, 99% of bonus and unit compensation expense and 100% of all other compensation provided to our NEOs was paid by NuStar Energy (as reflected in the disclosures in the NS 2017 Form 10-K). Accordingly, the following tables only include disclosure with respect to the NuStar GP Holdings restricted units that we provided to our NEOs:

Summary Compensation Table (with respect to 2017 and 2016 only);
Grants of Plan-Based Awards During the Year Ended December 31, 2017;
Outstanding Equity Awards at December 31, 2017; and
Option Exercises and Units Vested During the Year Ended December 31, 2017.

Prior to March 1, 2016, NuStar GP, LLC maintained pension and benefit plans for officers and other employees, and NuStar Energy reimbursed NuStar GP, LLC for the associated costs. Following the March 1, 2016 employee transfer and assignment to NuStar Services Co, NuStar Energy continues to fund those plans, through its subsidiary, NuStar Services Co. As a result, we have omitted the following tables from our disclosure:

Pension Benefits For the Year Ended December 31, 2017;
Nonqualified Deferred Compensation For the Year Ended December 31, 2017; and
Potential Payments Upon Termination or Change of Control.

Please see the NS 2017 Form 10-K for disclosure of the compensation of certain NuStar GP, LLC and NuStar Services Co officers (who also serve as our NEOs) for their services for NuStar Energy.

SUMMARY COMPENSATION TABLE

The following table provides a summary of compensation paid by us for the years ended December 31, 2017 and December 31, 2016 to our Chief Executive Officer, Chief Financial Officer and our three other most highly compensated executive officers serving during 2017. Mr. Oliver and Mr. Truby were not considered “executive officers” for SEC reporting purposes prior to 2017 and, accordingly, their compensation is reported only with respect to 2017.

The amounts reported represent the grant date fair value of grants of NuStar GP Holdings restricted units. The grant date fair value for restricted units was determined by multiplying the number of NuStar GP Holdings restricted units that were granted by the NYSE closing unit price of NuStar GP Holdings common units on the date of grant. Please see the footnotes to the Grants of Plan-Based Awards During the Year Ended December 31, 2017 table below for information regarding the vesting schedule. For information regarding the assumptions made in the valuation of restricted units, see Note 12 of the Notes to the Consolidated Financial Statements in Item 8.

PAY RATIO

As required by SEC regulations, we are providing the following information regarding the ratio of the annual total compensation of our President and Chief Executive Officer, Mr. Barron, to the median of the annual total compensation of our employees for our last completed fiscal year.

As described above in “Compensation Discussion and Analysis,” we receive all management and administrative services from NuStar Services Co, and we pay an administrative services fee to NuStar Services Co for those services. We only have 10 employees, each of whom also serves as an officer of NuStar Services Co. No portion of the administrative services fee that we pay to NuStar Services Co is allocated to the compensation of our employees. The only compensation that we provide to our employees is an annual award of restricted units, the grant date fair value of which is reflected in the Summary Compensation Table above for our NEOs.

For 2017:

the median of the annual total compensation of all of our employees (other than our President and Chief Executive Officer) was $46,481; and
the annual total compensation of our President and Chief Executive Officer, as reported in the Summary Compensation Table above, was $208,380.

Accordingly, for 2017, the ratio of the annual total compensation of our President and Chief Executive Officer to the median of the annual total compensation of all of our employees was 4.5 to 1. To determine this ratio, we examined the annual total compensation of each of our employees (other than our President and Chief Executive Officer) as of December 31, 2017, identified the median employee as of that date and calculated the ratio. The annual total compensation used to determine the ratio, which consists solely of the grant date fair value of the annual restricted unit award, is calculated in the same manner as the annual total compensation reflected in the Summary Compensation Table above. We did not make any assumptions, adjustments or estimates to identify the median employee or to determine the annual total compensation for each employee.

NuStar GP Holdings restricted units were approved by our Compensation Committee on October 18, 2017, and the grant date for these restricted units was set at that time for the date that was as soon as administratively practicable after the meeting and no earlier than the third business day following our third quarter earnings release. The restricted units were awarded pursuant to the LTI Plan and vest 1/5 annually over five years beginning on the first anniversary of the grant date. All grantees receiving NuStar GP Holdings restricted units are entitled to receive an amount in cash equal to the product of (a) the number of restricted units granted to the grantee that remain outstanding and unvested as of the record date for such quarter and (b) the quarterly distribution declared by our Board for such quarter with respect to our common units.

Table of Contents

At the effective time of the Merger, each outstanding award of NuStar GP Holdings restricted units will be converted, on the same terms and conditions as were applicable to the awards immediately prior to the Merger, into an award of NuStar Energy restricted units. The number of NuStar Energy restricted units subject to the converted awards will be determined as provided in the Merger Agreement. Each of our NEOs has agreed and acknowledged that the Merger will not be deemed to trigger a “change of control” as defined under any NuStar GP Holdings plan or award, and has waived any rights to vesting, payment or other benefit thereunder that would arise upon a “change of control,” to which he or she might otherwise have been entitled.

The grant date fair value for restricted units was determined by multiplying the number of NuStar GP Holdings restricted units that were granted by the NYSE closing unit price of our common units on the date of grant, $15.65.

OUTSTANDING EQUITY AWARDS
AT DECEMBER 31, 2017

The following table provides information regarding our NEOs’ unvested NuStar GP Holdings restricted units as of December 31, 2017. The value of the restricted units reported below is equal to the number of restricted units reflected in the table multiplied by $15.70, our common unit closing price on the NYSE on December 29, 2017 (the last trading day of 2017). The footnotes to the table describe the vesting schedules for the unvested restricted units reflected in the table. None of our NEOs had outstanding unit options as of December 31, 2017.

At the effective time of the Merger, each outstanding award of NuStar GP Holdings restricted units will be converted, on the same terms and conditions as were applicable to the awards immediately prior to the Merger, into an award of NuStar Energy restricted units. The number of NuStar Energy restricted units subject to the converted awards will be determined as provided in the Merger Agreement. Each of our NEOs has agreed and acknowledged that the Merger will not be deemed to trigger a “change of control” as defined under any NuStar GP Holdings plan or award, and has waived any rights to vesting, payment or other benefit thereunder that would arise upon a “change of control,” to which he or she might otherwise have been entitled.

The amounts reported represent the grant date fair value for the November 16, 2017 grant of NuStar GP Holdings restricted units to our non-employee directors (6,709 restricted units for Mr. Greehey, as Chairman, and 5,111 restricted units for each of the other non-employee directors) based on the closing price of our common units on the NYSE on November 16, 2017 ($15.65). Restricted units are contractual obligations of NuStar GP Holdings to provide common units upon vesting. For information regarding the assumptions made in the valuation of restricted units, see Note 12 of the Notes to the Consolidated Financial Statements in Item 8.

As of December 31, 2017, each director held the following aggregate number of restricted units. None of the directors had outstanding unit options as of December 31, 2017.

Mr. Barron is not compensated for his service as a director. The units in the table were awarded in connection with his service as President and Chief Executive Officer of NuStar GP, LLC and NuStar Services Co, as described under “Compensation Discussion and Analysis” above.

Our non-employee directors do not participate in these plans. Prior to March 1, 2016, pension and benefit plans were maintained by our wholly owned subsidiary, NuStar GP, LLC, and costs incurred by us related to pension and other retirement benefit plans were reimbursed by NuStar Energy. Beginning March 1, 2016, these plans are maintained by NuStar Services Co, a wholly owned subsidiary of NuStar Energy, and funding for these plans is provided by NuStar Services Co.

Mr. Barron was not compensated for his service as a director of NuStar GP Holdings.

Table of Contents

Directors who are employees receive no compensation (other than reimbursement of expenses) for serving as directors. The compensation structure for our non-employee directors consists of the following components: (1) an annual cash retainer; (2) an annual restricted unit grant; (3) an additional cash payment for each meeting attended in-person and telephonically; (4) an additional annual cash retainer for each committee chair; and (5) an additional annual retainer for the Chairman of the Board, which includes both cash and restricted units.

During 2017, the Compensation Committee engaged EPPA to review our non-employee directors’ compensation. Based on its review, EPPA recommended, and our Board and Compensation Committee approved effective July 27, 2017, increasing the annual cash retainer from $55,000 to $60,000 and increasing the value of the annual equity award from $70,000 to $80,000, resulting in the compensation structure for our non-employee directors set forth in the table below.

Non-Employee Director Compensation Component

Annual Cash Retainer ($)
60,000
 
Annual Restricted Unit Grant ($ value of restricted units)
80,000

5,000
 
Annual Chairman of the Board Retainer ($25,000 value in restricted units/$50,000 cash)
75,000
 
 
 

As described above, we supplement the cash compensation paid to non‑employee directors with an annual grant of restricted units that vests in equal annual installments over a three-year period. We believe this annual grant of restricted units increases the non-employee directors’ identification with the interests of our unitholders through ownership of our common units. Upon a non-employee director’s initial election to the Board, the director will receive a grant of restricted units.

In the event of a “change of control” as defined in the LTI Plan, all unvested restricted units previously granted immediately become vested. The LTI Plan also contains anti-dilution provisions providing for an adjustment in the number of restricted units that have been granted to prevent dilution of benefits in the event there is a change in our capital structure that affects our common units. At the effective time of the Merger, each outstanding award of NuStar GP Holdings restricted units will be converted, on the same terms and conditions as were applicable to the awards immediately prior to the Merger, into an award of NuStar Energy restricted units. The number of NuStar Energy restricted units subject to the converted awards will be determined as provided in the Merger Agreement. Each of our directors has agreed and acknowledged that the Merger will not be deemed to trigger a “change of control” as defined under any NuStar GP Holdings plan or award, and has waived any rights to vesting, payment or other benefit thereunder that would arise upon a “change of control,” to which he or she might otherwise have been entitled.

As of February 20, 2018, 42,953,132 NuStar GP Holdings common units and 93,182,030 NuStar Energy common units were outstanding. Beneficial ownership is calculated in accordance with Rule 13d-3 of the Exchange Act. Phantom units (which we refer to as “restricted units” for purposes of this Annual Report) awarded under our long-term incentive plan and restricted units awarded under NuStar GP, LLC’s long-term incentive plan are rights to receive NuStar GP Holdings common units or NuStar Energy common units, respectively, upon vesting and, as such, may not be disposed of or voted until vested. The restricted units do not vest within 60 days after February 20, 2018. Accordingly, the restricted units set forth in the table below are not included in the calculation of beneficial ownership pursuant to Rule 13d-3 and are not reflected in the table above. As described below in Item 13, on February 7, 2018, we, NuStar Energy, Riverwalk Logistics, L.P., NuStar GP, LLC, Riverwalk Holdings, LLC and Merger Sub entered into the Merger Agreement pursuant to which Merger Sub will merge with and into NuStar GP Holdings with NuStar GP Holdings being the surviving entity, such that NuStar Energy will be the sole member of NuStar GP Holdings following the Merger. At the effective time of the Merger, each NuStar GP Holdings common unit outstanding will be converted into the right to receive 0.55 of a NuStar Energy common unit and each award of NuStar GP Holdings restricted units will be converted into an award of NuStar Energy restricted units, in each case as provided in the Merger Agreement.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE

TRANSACTIONS WITH MANAGEMENT AND OTHERS

In January 2007, our Board adopted a written related person transaction policy that codifies our prior practice. For purposes of the policy, a related person transaction is one that is not available to all employees generally or involves $10,000 or more when aggregated with similar transactions. The policy requires that any transaction between NuStar GP Holdings and any: (1) vice president, Section 16 officer, director or any other person designated for these purposes as an officer by the Board; (2) unitholder owning greater than 5% of NuStar Energy or NuStar GP Holdings; (3) immediate family member of any such officer or director; or (4) entity owned or controlled by any of (1), (2) or (3) (or in which any of (1), (2) or (3) owns a 5% or greater ownership interest or controls such entity) must be approved by the disinterested members of the Board. In addition, the policy provides that such officers and directors have an affirmative obligation to inform our Corporate Secretary of his or her immediate family members, as well as any entities in which he or she controls or owns 5% or more.

RELATIONSHIP WITH NUSTAR ENERGY

Due to our ownership of NuStar GP, LLC and Riverwalk Holdings, LLC, as of December 31, 2017, we indirectly owned:

the general partner interest in NuStar Energy, through our indirect 100% ownership interest in Riverwalk Logistics, L.P.;
100% of NuStar Energy’s incentive distribution rights; and
10,214,626 common units of NuStar Energy.

Our officers also are officers of NuStar GP, LLC, as well as certain subsidiaries of NuStar Energy, including NuStar Services Co. Our Chairman, William E. Greehey, also is the Chairman of the board of directors of NuStar GP, LLC. Our Board appointed NuStar GP, LLC’s directors and generally is responsible for oversight of the general partner of NuStar Energy. See “Security Ownership of Our Management and Directors” above for our common units and the common units of NuStar Energy owned by Mr. Greehey, as well as by our other directors and our executive officers.

See “Compensation Discussion and Analysis” above for a description of the Amended and Restated Services Agreement among NuStar GP Holdings, NuStar GP, LLC, NuStar Energy and NuStar Services Co.

MERGER AGREEMENT

On February 7, 2018, NuStar GP Holdings, NuStar Energy, Riverwalk Logistics, L.P., NuStar GP, LLC, Riverwalk Holdings, LLC and Merger Sub entered into the Merger Agreement pursuant to which Merger Sub will merge with and into NuStar GP Holdings with NuStar GP Holdings being the surviving entity, such that NuStar Energy will be the sole member of NuStar GP Holdings following the Merger. Pursuant to the Merger Agreement and at the effective time of the Merger, NuStar Energy’s partnership agreement will be amended and restated to, among other things, (1) cancel the incentive distribution rights held by the general partner of NuStar Energy, (2) convert the 2% general partner interest in NuStar Energy held by the general partner into a non-economic management interest and (3) provide the holders of NuStar Energy common units with voting rights in the election of the members of the board of directors of NuStar GP, LLC at an annual meeting, beginning in 2019.

At the effective time of the Merger, each outstanding NuStar GP Holdings common unit, other than those held by NuStar GP Holdings or its subsidiaries, will be converted into the right to receive 0.55 of a NuStar Energy common unit. All NuStar GP Holdings common units, when converted, will cease to be outstanding and will automatically be cancelled and no longer exist. No fractional NuStar Energy common units will be issued in the Merger; instead, each holder of NuStar GP Holdings’ common units otherwise entitled to receive a fractional NuStar Energy common unit will receive cash in lieu thereof. Furthermore, the 10,214,626 NuStar Energy common units currently owned by NuStar GP Holdings will be cancelled and will cease to exist.

At the effective time of the Merger, each outstanding award of NuStar GP Holdings restricted units will be converted, on the same terms and conditions as were applicable to the awards immediately prior to the Merger, into an award of NuStar Energy restricted units. The number of NuStar Energy restricted units subject to the converted awards will be determined as provided in the Merger Agreement. Each of our executive officers and directors has agreed and acknowledged that the Merger will not be deemed to trigger a “change of control” as defined under any NuStar GP Holdings plan or award, and has waived any rights to vesting, payment or other benefit thereunder that would arise upon a “change of control,” to which he or she might otherwise have been entitled.

Table of Contents

The Merger Agreement contains customary representations and warranties and covenants by each of the parties. Completion of the Merger is conditioned upon, among other things: (1) approval of the Merger Agreement by the affirmative vote of holders of a Unit Majority, as defined in the LLC Agreement; (2) the effectiveness of a registration statement on Form S-4 with respect to the issuance by NuStar Energy of its common units in connection with the Merger; (3) the absence of certain legal injunctions or impediments prohibiting the transactions; (4) the receipt of certain tax opinions from a nationally recognized tax counsel; and (5) the approval for the listing on the New York Stock Exchange of NuStar Energy’s common units to be issued in the Merger.

NuStar Energy entered into a Support Agreement, dated as of February 7, 2018 (the Support Agreement), with Merger Sub, WLG Holdings, LLC, a Texas limited liability company controlled by Mr. Greehey (WLG Holdings), Mr. Greehey (together, WLG Holdings and Mr. Greehey are referred to as the Greehey Unitholders), and, for limited purposes, NuStar GP Holdings, pursuant to which the Greehey Unitholders have agreed to vote in favor of the approval and adoption of the Merger Agreement, the approval of the Merger and any other action required in furtherance thereof submitted for the vote or written consent of NuStar GP Holdings unitholders. The Support Agreement will terminate (1) at the effective time of the Merger, (2) upon the termination of the Merger Agreement as provided therein, or (3) at such time as NuStar Energy and the Greehey Unitholders agree in writing to terminate the Support Agreement.

After the Merger, the NuStar GP, LLC board of directors is expected to consist of nine members, initially composed of the six members of the NuStar GP, LLC board of directors and our three independent directors (Mr. Burnett, Mr. Clingman and Ms. LeBlanc-Burley).

DIRECTOR INDEPENDENCE

Our business is managed under the direction of our Board. Our LLC Agreement provides for the Board to be divided into Class I, Class II and Class III directors, with each class serving a staggered three-year term. Our Board conducts its business through meetings of its members and its committees. Each committee has a written charter. During 2017, the Board held seven meetings, the Audit Committee held eight meetings, the Compensation Committee held two meetings and the Nominating/Governance Committee held one meeting. No member of the Board attended less than 75% of the meetings of the Board and committees of which he or she was a member during 2017. Our Board members, other than our Chairman of the Board, Mr. Greehey, and our President, Chief Executive Officer and director, Mr. Barron, did not attend our 2017 Annual Meeting of Unitholders on April 26, 2017. Mr. Greehey and Mr. Barron are expected to attend meetings of our unitholders.

INDEPENDENT DIRECTORS

The Board includes one member of management, Mr. Barron, President and Chief Executive Officer, and four non-management directors. The Board has determined that three of its four non-management directors meet the independence requirements of the NYSE listing standards as set forth in the NYSE Listed Company Manual. The independent directors are: Mr. Burnett, Mr. Clingman and Ms. LeBlanc-Burley.

Mr. Greehey, Chairman of the Board, also serves as the Chairman of the NuStar GP, LLC board of directors and, as of December 31, 2017, beneficially owned approximately 21% of our outstanding common units. Mr. Greehey is not an independent director under the NYSE’s listing standards.

Mr. Barron has been President and Chief Executive Officer since January 2014. Mr. Barron also serves as President and Chief Executive Officer of NuStar GP, LLC. As a member of management, Mr. Barron is not an independent director under the NYSE’s listing standards.

The Audit, Compensation and Nominating/Governance Committees of the Board are composed entirely of directors who meet the independence requirements of the NYSE listing standards. Each member of the Audit Committee also meets the additional independence standards for Audit Committee members set forth in the regulations of the SEC. For further information about the committees, see also Item 10 and Item 11 above.

INDEPENDENCE DETERMINATIONS

Under the NYSE listing standards, no director qualifies as independent unless the Board affirmatively determines that the director has no material relationship with NuStar GP Holdings. Based upon information requested from and provided by each director concerning their background, employment and affiliations, including commercial, industrial, banking, consulting, legal, accounting, charitable and familial relationships, the Board has determined that none of Mr. Burnett, Mr. Clingman or Ms. LeBlanc-Burley has any more than an immaterial relationship with NuStar GP Holdings, either directly or as a partner, stockholder or officer of an organization that has a relationship with NuStar GP Holdings and, therefore, each is independent under the NYSE listing standards.

As provided for under the NYSE listing standards, the Board has adopted categorical standards or guidelines to assist the Board in making its independence determinations with respect to each director. Under the NYSE listing standards, immaterial relationships that fall within the guidelines are not required to be disclosed in this Annual Report on Form 10-K.

An immaterial relationship falls within the guidelines adopted by the Board if it:
is not a relationship that would preclude a determination of independence under Section 303A.02(b) of the NYSE Listed Company Manual;
consists of charitable contributions by us to an organization where a director is an executive officer and does not exceed the greater of $1 million or 2% of the organization’s gross revenue in any of the last three years;
consists of charitable contributions by us to any organization with which a director, or any member of a director’s immediate family, is affiliated as an officer, director or trustee pursuant to a matching gift program of ours and made on terms applicable to employees and directors generally, or is in amounts that do not exceed $250,000 per year; and
is not required to be disclosed in this Annual Report on Form 10-K.

Our Corporate Governance Guidelines contain the director qualification standards, including the guidelines listed above, and are available on our website at www.nustargpholdings.com (under the “Corporate Governance” tab in the “Investors” section) or are available in print upon request to our Corporate Secretary at the address indicated on the cover page of this Annual Report on Form 10-K or corporatesecretary@nustarenergy.com.

PRESIDING DIRECTOR/MEETINGS OF NON-MANAGEMENT DIRECTORS

The Board has designated Mr. Clingman to serve as the Presiding Director for meetings of the non-management Board members outside the presence of management.

COMMUNICATIONS WITH THE BOARD, NON-MANAGEMENT DIRECTORS OR PRESIDING DIRECTOR

Unitholders and other interested parties may communicate with the Board, its non-management directors or the Presiding Director by sending a written communication in an envelope addressed to “Board of Directors,” “Non-Management Directors,” or “Presiding Director” in care of our Corporate Secretary at the address indicated on the cover page of this Annual Report on Form 10-K or corporatesecretary@nustarenergy.com.

AVAILABILITY OF GOVERNANCE DOCUMENTS

We have posted our Corporate Governance Guidelines, Code of Business Conduct and Ethics, Code of Ethics for Senior Financial Officers and the Charters of the Audit Committee, Compensation Committee and Nominating/Governance Committee on our website at www.nustargpholdings.com (under the “Corporate Governance” tab in the “Investors” section). Our governance documents are available in print to any unitholder of record who makes a written request to NuStar GP Holdings.

In the event that Units issued under the Plan are reacquired by the Partnership or the Company pursuant to any forfeiture provision, such Units shall again be available for the purposes of the Plan.

(ii)     Limits on Transfer of Awards . No Award and no right under any such Award may be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by a Participant otherwise than by will or by the laws of descent and distribution and any such purported assignment, alienation, pledge, attachment, sale, transfer or encumbrance shall be void and unenforceable against the Company or any Affiliate.

No Units or other securities shall be delivered pursuant to any Award until payment in full of any amount required to be paid pursuant to the Plan, the terms of any Award and/or any applicable Award agreement (including, without limitation, any exercise price or any tax withholding) is receivable by the Employer or applicable Affiliate thereof. Such payment may be made by such method or methods and in such form or forms as the Committee shall determine, including, without limitation, cash, other Awards, withholding of Units, or any combination thereof; provided that the combined value, as determined by the Committee, of all cash and cash equivalent and the value of any such Units or other property so tendered to the Employer or applicable Affiliate thereof, as of the date of such tender, is at least equal to the full amount required to be paid to the Employer pursuant to the Plan, the terms of any Award and/or any applicable Award agreement.
(vii)     Change of Control . Upon a Change of Control, all Awards shall automatically vest and become payable or exercisable, as the case may be, in full. In this regard, all Restricted Periods shall terminate

8



and all performance criteria, if any, shall be deemed to have been achieved at the maximum level. To the extent an Option is not exercised, upon the Change of Control, the Committee may, in its discretion, cancel such Award or provide for an assumption of such Award or a replacement grant on substantially the same terms; provided, however, upon any cancellation of an Option that has a positive “spread,” the holder shall be paid an amount in cash and/or other property, as determined by the Committee, equal to such “spread” of such Option and, in the event there is no positive “spread,” such Option shall be cancelled without payment of consideration therefor.
6.4     Performance Based Awards .
(i)     Grant of Performance Awards . The Committee may issue Performance Awards in the form of Performance Units, Performance Cash, or DERs to Participants subject to the Performance Goals and Performance Period as it shall determine and set forth in the terms of the Award and/or any Award agreement.

The Performance Goals may be based on achievement of balance sheet or income statement objectives, or any other objectives established by the Committee.

Upon or as soon as reasonably practicable following the vesting of each Unit under a Unit Award that is subject to a Restricted Period, subject to satisfying the tax withholding obligations of Section 8.2, the Participant shall be entitled to have the restrictions removed from his or her Unit certificate (or book-entry account, as applicable) so that the Participant then holds an unrestricted Unit.

SECTION 8.    General Provisions.
8.1     No Rights to Awards . No Person shall have any claim to be granted any Award, and there is no obligation for uniformity of treatment of Participants. The terms and conditions of Awards need not be the same with respect to each Participant.
8.2     Withholding . The Employer or any Affiliate is authorized to withhold from any Award, from any payment due or transfer made under any Award or from any compensation or other amount owing to a Participant the amount (in cash, Units, other securities, Units that would otherwise be issued pursuant to such Award or other property) of any applicable taxes payable in respect of the grant of an Award, the lapse of restrictions thereon, or any payment or transfer under an Award or under the Plan and to take such other action as may be necessary in the opinion of the Employer (or applicable Affiliate) to satisfy all obligations for the payment of such taxes. In the event that

10



Units that would otherwise be issued pursuant to an Award are used to satisfy such withholding obligations, the number of Units which may be so withheld or surrendered shall be limited to the number of Units that according to generally accepted accounting principles would not result in liability accounting for the entirety of the award.
8.3     No Right to Employment . The grant of an Award shall not be construed as giving a Participant the right to be retained in the employ of the Company, the Partnership, Partnership Sub or any Affiliate of any of the foregoing or to remain on the Board or other directorship, as applicable. Further, the Company, the Partnership, Partnership Sub or an applicable respective Affiliate of any of the foregoing may at any time dismiss a Participant from employment, free from any liability or any claim under the Plan, unless otherwise expressly provided in the Plan, the terms of any Award and/or in any Award agreement.
8.4     Governing Law . The validity, construction, and effect of the Plan and any rules and regulations relating to the Plan shall be determined in accordance with the laws of the State of Delaware and applicable federal law.
8.5     Severability .

8.6     Other Laws . The Committee may refuse to issue or transfer any Units or other consideration under an Award if, in its sole discretion, it determines that the issuance or transfer of such Units or such other consideration might violate any applicable law or regulation, the rules of the principal securities exchange on which the Units are then traded, or entitle the Partnership or an Affiliate to recover the entire then Fair Market Value thereof under Section 16(b) of the Exchange Act, and any payment tendered to the Employer or applicable Affiliate thereof by a Participant, other holder or beneficiary in connection with the exercise of such Award shall be promptly refunded to the relevant Participant, holder or beneficiary.
8.7     No Trust or Fund Created . Neither the Plan nor the Award shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between the Company or any Affiliate and a Participant or any other Person. To the extent that any Person acquires a right to receive payments from the Company, the Partnership, Partnership Sub or any Affiliate of any of the foregoing pursuant to an Award, such right shall be no greater than the right of any general unsecured creditor of the Company, the Partnership, Partnership Sub or any applicable Affiliate.
8.8     No Fractional Units . No fractional Units shall be issued or delivered pursuant to the Plan or any Award, and the Committee shall determine whether cash, other securities, or other property shall be paid or transferred in lieu of any fractional Units or whether such fractional Units or any rights thereto shall be canceled, terminated, or otherwise eliminated.
8.9     Headings . Headings are given to the Sections and subsections of the Plan solely as a convenience to facilitate reference. Such headings shall not be deemed in any way material or relevant to the construction or interpretation of the Plan or any provision thereof.

8.12     No Guarantee of Tax Consequences . None of the Board, the Company, the Partnership, Partnership Sub or any Affiliate of any of the foregoing makes any commitment or guarantee that any federal, state, local or other tax treatment will (or will not) apply or be available to any Participant (or to any person claiming through or on behalf of any Participant) or assumes any liability or responsibility with respect to taxes and penalties and interest thereon arising hereunder with respect to any Participant (or to any person claiming through or on behalf of any Participant).
8.13     Section 409A . This Plan, the Awards and the terms of all Awards and/or Award agreements are intended to either comply with or be exempt from Section 409A of the Code, and ambiguous provisions hereof, if any, shall be construed and interpreted in a manner consistent with such intent. The Company and its respective Affiliates make no representations that the Plan, the administration of the Plan, the Awards, the terms of the Awards and/or Award agreements or amounts payable hereunder comply with, or are exempt from, Section 409A of the Code, and undertake no obligation to ensure such compliance or exemption. For purposes of Section 409A of the Code, each payment or amount due under this Plan shall be considered a separate payment, and a Participant’s entitlement to a series of payments under this Plan shall be treated as an entitlement to a series of separate payments. Notwithstanding any other provision of the Plan, the terms of an Award and/or any Award agreement to the contrary, if a Participant is a “specified employee” under Section 409A of the Code, except to the extent permitted thereunder, no benefit or payment that is not otherwise exempt from Section 409A of the Code (after taking into account all applicable exceptions thereunder, including to the exceptions for short-term deferrals and for “separation pay only upon an involuntary separation from service”) shall be made to that Participant under the Plan or the affected Award granted thereunder on account of the Participant’s “separation from service,” as defined in Section 409A of the Code, until the later of the date prescribed for payment in the Plan or the affected Award granted thereunder and the first (1st) day of the seventh (7th) calendar month that begins after the date of the Participant’s separation from service (or, if earlier, the date of death of the Participant). Unless otherwise provided in the terms of any Award and/or Award agreement, any amount that is otherwise payable within the delay period described in the immediately preceding sentence will be aggregated and paid in a lump sum without interest.
SECTION 9.    Term of the Plan.
The fourth amendment and restatement of the Plan became effective on January 1, 2014. The current amendment and restatement was approved by the holders of Units and became effective January 28, 2016 (the “ Effective Date ”). The Plan shall continue until the date terminated by the Board or Units are no longer available for grants of Awards under the Plan, whichever occurs first; provided, however, that notwithstanding the foregoing, no Award shall be made under the Plan after the tenth anniversary of the Effective Date, January 28, 2026. However, unless otherwise expressly provided in the Plan or in the terms of an Award and/or any applicable Award agreement, any Award granted prior to such termination, and the authority of the Board or the Committee to amend, alter, adjust, suspend, discontinue, or terminate any such Award or to waive any conditions or rights under such Award, shall extend beyond such termination date. In the event sponsorship of the Plan is transferred from the Company to an Affiliate thereof, the term of the plan shall continue until the tenth anniversary of the Effective Date, January 28, 2026, unless terminated earlier as provided herein.

SECTION 10.    Special Provisions Applicable to Covered Participants.
Awards subject to Performance Criteria paid to Covered Participants under this Plan shall be governed by the conditions of this Section 10 in addition to the requirements of Section 6.4, above. Should conditions set forth under this Section 10 conflict with the requirements of Section 6.4, the conditions of this Section 10 shall prevail.
10.1     Establishment of Performance Measures, Goals or Criteria . All Performance Measures, Goals, or Criteria relating to Covered Participants for a relevant Performance Period shall be established by the Committee in writing prior to the beginning of the Performance Period, or by such other later date for the Performance Period as may be permitted under Section 162(m) of the Code. The Performance Goals may be identical for all Participants or, at the discretion of the Committee, may be different to reflect more appropriate measures of individual performance.
10.2     Performance Goals . The Committee shall establish the Performance Goals relating to Covered Participants for a Performance Period in writing. Performance Goals may include alternative and multiple Performance Goals and may be based on one or more business and/or financial criteria. In establishing the Performance Goals for the Performance Period, the Committee in its discretion may include one or any combination of the following criteria in either absolute or relative terms, for the Partnership or any Affiliate:
(i)    Increased revenue;
(ii)    Net income measures (including but not limited to income after capital costs and income before or after taxes);
(iii)    Unit price measures (including but not limited to growth measures and total unitholder return);
(iv)    Market share;
(v)    Earnings per unit (actual or targeted growth);

(xvi)    Pipeline and terminal utilization;
(xvii)    Total market value; and
(xviii)    Corporate values measures (including ethics and compliance, environmental, and safety).
10.3     Compliance with Section 162(m) . The Performance Goals must be objective and must satisfy third party “objectivity” standards under Section 162(m) of the Code, and the regulations promulgated thereunder. In interpreting Plan provisions relating to Awards subject to Performance Goals paid to Covered Participants, it is the intent of the Plan to conform with the standards of Section 162(m) of the Code and Treasury Regulation §1.162-27(e)(2)(i), and the Committee in establishing such goals and interpreting the Plan shall be guided by such provisions.
10.4     Adjustments . The Committee is authorized to make adjustments in the method of calculating attainment of Performance Goals in recognition of: (i) extraordinary or non-recurring items, (ii) changes in tax laws, (iii) changes in generally accepted accounting principles or changes in accounting principles, (iv) charges related to restructured or discontinued operations, (v) restatement of prior period financial results, and (vi) any other unusual, non-recurring gain or loss that is separately identified and quantified in the Company’s financial statements. Notwithstanding the foregoing, the Committee may, at its sole discretion, reduce the performance results upon which Awards are based under the Plan, to offset any unintended result(s) arising from events not anticipated when the Performance Goals were established, or for any other purpose, provided that such adjustment is permitted by Section 162(m) of the Code.
10.5     Discretionary Adjustments . The Performance Goals shall not allow for any discretion by the Committee as to an increase in any Award, but discretion to lower an Award is permissible.
10.6     Certification . The Award and payment of any Award under this Plan to a Covered Participant with respect to a relevant Performance Period shall be contingent upon the attainment of the Performance Goals that are applicable to such Covered Participant. The Committee shall certify in writing prior to payment of any such Award that such applicable Performance Goals relating to the Award are satisfied. Approved minutes of the Committee may be used for this purpose.
10.7     Other Considerations . All Awards to Covered Participants under this Plan shall be further subject to such other conditions, restrictions, and requirements as the Committee may determine to be necessary to carry out the purpose of this Section 10.

Exhibit 99.01

Report of Independent Registered Public Accounting Firm

The Board of Directors of NuStar GP, LLC
and Unitholders of NuStar Energy L.P.:

Opinion on the Consolidated Financial Statements
We have audited the accompanying consolidated balance sheets of NuStar Energy L.P. (a Delaware limited partnership) and subsidiaries (the “Partnership”) as of December 31, 2017 and 2016, the related consolidated statements of income, comprehensive income, partners’ equity, and cash flows for each of the years in the three‑year period ended December 31, 2017, and the related notes (collectively, the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Partnership as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the years in the three‑year period ended December 31, 2017, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Partnership’s internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 28, 2018 expressed an unqualified opinion on the effectiveness of the Partnership’s internal control over financial reporting.
Basis for Opinion
These consolidated financial statements are the responsibility of the Partnership’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Partnership in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.
We have served as the Partnership’s auditor since 2004.

Report of Independent Registered Public Accounting Firm
The Board of Directors of NuStar GP, LLC
and Unitholders of NuStar Energy L.P.:

Opinion on Internal Control Over Financial Reporting
We have audited NuStar Energy L.P. (a Delaware limited partnership) and subsidiaries’ (the “Partnership”) internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Partnership maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the consolidated balance sheets of the Partnership as of December 31, 2017 and 2016, the related consolidated statements of income, comprehensive income, partners’ equity, and cash flows for each of the years in the three-year period ended December 31, 2017, and the related notes (collectively, the “consolidated financial statements”), and our report dated February 28, 2018 expressed an unqualified opinion on those consolidated financial statements.
The Partnership acquired Navigator Energy Services, LLC during 2017, and management excluded from its assessment of the effectiveness of the Partnership’s internal control over financial reporting as of December 31, 2017, Navigator Energy Services, LLC’s internal control over financial reporting whose financial statements reflect 23 percent of total assets and 2 percent of total revenues of the related consolidated financial statement amounts of NuStar Energy L.P. as of and for the year ended December 31, 2017. Our audit of internal control over financial reporting of the Partnership also excluded an evaluation of the internal control over financial reporting of Navigator Energy Services, LLC.
Basis for Opinion
The Partnership’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Partnership’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Partnership in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NUSTAR ENERGY L.P. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Years Ended December 31, 2017 , 2016 and 2015

1. ORGANIZATION AND OPERATIONS
Organization
NuStar Energy L.P. (NYSE: NS) is engaged in the transportation of petroleum products and anhydrous ammonia, and the terminalling, storage and marketing of petroleum products. Unless otherwise indicated, the terms “NuStar Energy,” “NS,” “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 or NSH) (NYSE: NSH) owns our general partner, Riverwalk Logistics, L.P., and owns an approximate 11% common limited partner interest in us as of December 31, 2017 .

Employee Transfer from NuStar GP, LLC. On March 1, 2016, NuStar GP, LLC, the general partner of our general partner and a wholly owned subsidiary of NuStar GP Holdings, transferred and assigned to NuStar Services Company LLC (NuStar Services Co), a wholly owned subsidiary of NuStar Energy, all of NuStar GP, LLC’s employees and related benefit plans, programs, contracts and policies (the Employee Transfer). As a result of the Employee Transfer, we pay employee costs directly and sponsor the long-term incentive plan and other employee benefit plans. Please refer to Note 17 for further discussion of the Employee Transfer and our related party agreements, Note 22 for a discussion of our employee benefit plans and Note 23 for a discussion of our long-term incentive plan.

Recent Developments
Merger. On February 7, 2018, NuStar Energy, Riverwalk Logistics, L.P., NuStar GP, LLC, Marshall Merger Sub LLC, a wholly owned subsidiary of NuStar Energy (Merger Sub), Riverwalk Holdings, LLC and NuStar GP Holdings, LLC (NuStar GP Holdings) entered into an Agreement and Plan of Merger (the Merger Agreement) pursuant to which Merger Sub will merge with and into NuStar GP Holdings with NuStar GP Holdings being the surviving entity (the Merger), such that NuStar Energy will be the sole member of NuStar GP Holdings following the Merger. Pursuant to the Merger Agreement and at the effective time of the Merger, our partnership agreement will be amended and restated to, among other things, (i) cancel the incentive distribution rights held by our general partner, (ii) convert the 2% general partner interest in NuStar Energy held by our general partner into a non-economic management interest and (iii) provide the holders of our common units with voting rights in the election of the members of the board of directors of NuStar GP, LLC at an annual meeting, beginning in 2019. The Merger is subject to the satisfaction or waiver of certain conditions, including approval of the Merger Agreement by NuStar GP Holdings unitholders. Please refer to Note 28 for further discussion of the Merger.

Hurricane Activity. In the third quarter of 2017, parts of the Caribbean and Gulf of Mexico experienced three major hurricanes. Several of our facilities were affected by the hurricanes, but our St. Eustatius terminal experienced the most damage and was temporarily shut down. We incurred approximately $2.6 million of operating expenses to repair minor property damage at several of our domestic terminals. Additionally, we recorded a $5.0 million loss in “Other (expense) income, net” in the consolidated statements of income in the third quarter of 2017 for property damage at our St. Eustatius terminal, which represents the amount of our property deductible under our insurance policy. The hurricane impacts lowered revenues for our bunker fuel operations in our fuels marketing segment and lowered throughput and associated handling fees in our storage segment in the third and fourth quarters of 2017. We received insurance proceeds of $12.5 million in 2017 for damages at our St. Eustatius terminal, of which $3.8 million was for business interruption and the remainder was used for repairs and cleanup. Proceeds from business interruption insurance are included in “Operating expenses” in the consolidated statements of income and in “Cash flows from operating activities” in the consolidated statements of cash flows. In January 2018, we received $87.5 million of insurance proceeds in settlement of our property damage claim for our St. Eustatius terminal. We expect that the costs to repair the property damage at the terminal will not exceed the value of insurance proceeds received.

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 4, 12 and 19 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

NUSTAR ENERGY L.P. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)



settlement of the Axeon Term Loan, and our obligation to provide ongoing credit support to Axeon ceased. Please refer to Notes 7 and 15 for further discussion of the Axeon Term Loan and related credit support.

Operations
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.
Pipeline. We own 3,130 miles of refined product pipelines and 1,930 miles of crude oil pipelines, as well as approximately 5.0 million barrels of storage capacity, which comprise our Central West System. In addition, we own 2,370 miles of refined product pipelines, consisting of the East and North Pipelines, and a 2,000 -mile ammonia pipeline, which comprise our Central East System. The East and North Pipelines have storage capacity of approximately 6.8 million barrels. 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 terminal and storage facilities in the United States, Canada, Mexico, the Netherlands, including St. Eustatius in the Caribbean, and the United Kingdom, with approximately 84.8 million barrels of storage capacity. Our terminal and storage facilities provide storage, handling and other services on a fee basis for petroleum products, crude oil, specialty chemicals and other liquids.
Fuels Marketing. Within our fuels marketing operations, we purchase petroleum products for resale. The activities of the fuels marketing segment expose us to the risk of fluctuations in commodity prices, which has a direct impact on the segment’s results of operations. We enter into derivative contracts to attempt to mitigate the effect of commodity price fluctuations.
We ceased marketing crude oil in the second quarter of 2017 and exited our heavy fuels trading operations in the third quarter of 2017. These actions are in line with our goal of reducing our exposure to commodity margins, and instead focusing on our core, fee-based pipeline and storage segments. The only operations remaining in our fuels marketing segment are our bunkering operations at our St. Eustatius and Texas City terminals, as well as certain of our blending operations.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Consolidation
The accompanying consolidated financial statements represent the consolidated operations of the Partnership and our subsidiaries. Inter-partnership balances and transactions have been eliminated in consolidation. The operations of certain pipelines and terminals in which we own an undivided interest are proportionately consolidated in the accompanying consolidated financial statements.
Use of Estimates
The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (GAAP) 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. On an ongoing basis, management reviews its estimates based on currently available information. Management may revise estimates due to changes in facts and circumstances.
Cash and Cash Equivalents
Cash equivalents are all highly liquid investments with an original maturity of three months or less when acquired.

Accounts Receivable
Accounts receivable represent valid claims against non-affiliated customers for products sold or services rendered. We extend credit terms to certain customers after review of various credit indicators, including the customer’s credit rating. Outstanding customer receivable balances are regularly reviewed for possible non-payment indicators and allowances for doubtful accounts are recorded based upon management’s estimate of collectability at the time of its review.
Inventories
Inventories consist of petroleum products, materials and supplies. Inventories, except those associated with a qualifying fair value hedge, are valued at the lower of cost or net realizable value. Cost is determined using the weighted-average cost method. Our inventory, other than materials and supplies, consists of one end-product category, petroleum products, which we include in the fuels marketing segment. Accordingly, we determine lower of cost or net realizable value adjustments on an aggregate

9


NUSTAR ENERGY L.P. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)



basis. Inventories associated with qualifying fair value hedges are valued at current market prices. Materials and supplies are valued at the lower of average cost or net realizable value.
Property, Plant and Equipment
We record additions to property, plant and equipment, including reliability and strategic capital expenditures, at cost. Repair and maintenance costs associated with existing assets that are minor in nature and do not extend the useful life of existing assets are charged to operating expenses as incurred. Depreciation of property, plant and equipment is recorded on a straight-line basis over the estimated useful lives of the related assets. When property or equipment is retired, sold or otherwise disposed of, the difference between the carrying value and the net proceeds is recognized in “Other (expense) income, net” in the consolidated statements of income in the year of disposition.

We capitalize overhead costs and interest costs incurred on funds used to construct property, plant and equipment while the asset is under construction. The overhead costs and capitalized interest are recorded as part of the asset to which they relate and are amortized over the asset’s estimated useful life as a component of depreciation expense.
Goodwill
We assess goodwill for impairment annually on October 1, or more frequently if events or changes in circumstances indicate it might be impaired. We have the option to first assess qualitative factors to determine whether it is necessary to perform a quantitative goodwill impairment test. We performed a quantitative goodwill impairment test as of October 1, 2017 and 2016, and determined that no impairment charges occurred.

We calculate the estimated fair value of each of our reporting units using a weighted-average of values calculated using an income approach and a market approach. The income approach involves estimating the fair value of each reporting unit by discounting its estimated future cash flows using a discount rate that would be consistent with a market participant’s assumption. The market approach bases the fair value measurement on information obtained from observed stock prices of public companies and recent merger and acquisition transaction data of comparable entities.
Our reporting units to which goodwill has been allocated consist of the following:
crude oil pipelines;
refined product pipelines;
terminals, excluding our St. Eustatius and Point Tupper facilities and our refinery crude storage tanks; and
bunkering activity at our St. Eustatius and Point Tupper facilities.

The quantitative impairment test for goodwill consists of a two-step process. Step 1 compares the fair value of the reporting unit to its carrying value including goodwill. The carrying value of each reporting unit equals the total identified assets (including goodwill) less the sum of each reporting unit’s identified liabilities. We used reasonable and supportable methods to assign the assets and liabilities to the appropriate reporting units in a consistent manner. If the carrying value exceeds fair value, there is a potential impairment and step 2 must be performed to determine the amount of goodwill impairment. Step 2 compares the carrying value of the reporting unit’s goodwill to its implied fair value using a hypothetical allocation of the reporting unit’s fair value. If the goodwill carrying value exceeds its implied fair value, the excess is reported as impairment.
Impairment of Long-Lived Assets
We review long-lived assets, including property, plant and equipment, for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. We evaluate recoverability using undiscounted estimated net cash flows generated by the related asset or asset group. If the results of that evaluation indicate that the undiscounted cash flows are less than the carrying amount of the asset (i.e., the asset is not recoverable) we perform an impairment analysis. If our intent is to hold the asset for continued use, we determine the amount of impairment as the amount by which the net carrying value exceeds its fair value. If our intent is to sell the asset, and the criteria required to classify an asset as held for sale are met, we determine the amount of impairment as the amount by which the net carrying amount exceeds its fair value less costs to sell. We believe that the carrying amounts of our long-lived assets as of December 31, 2017 are recoverable.
Income Taxes
We are a limited partnership and generally are not subject to federal or state income taxes. Accordingly, our taxable income or loss, which may vary substantially from income or loss reported for financial reporting purposes, is generally included in the federal and state income tax returns of our partners. For transfers of publicly held units subsequent to our initial public offering,

10


NUSTAR ENERGY L.P. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)



we have made an election permitted by Section 754 of the Internal Revenue Code (the Code) to adjust the common unit purchaser’s tax basis in our underlying assets to reflect the purchase price of the units. This results in an allocation of taxable income and expenses to the purchaser of the common units, including depreciation deductions and gains and losses on sales of assets, based upon the new unitholder’s purchase price for the common units.
We conduct certain of our operations through taxable wholly owned corporate subsidiaries. We account for income taxes related to our taxable subsidiaries using the asset and liability method. Under this method, we recognize deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. We measure deferred taxes using enacted tax rates expected to apply to taxable income in the year those temporary differences are expected to be recovered or settled.
We recognize a tax position if it is more likely than not that the tax position will be sustained, based on the technical merits of the position, upon examination. We record uncertain tax positions in the financial statements at the largest amount of benefit that is more likely than not to be realized. We had no unrecognized tax benefits as of December 31, 2017 and 2016 .
 
NuStar Energy and certain of its subsidiaries file income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. For U.S. federal and state purposes, as well as for our major non-U.S. jurisdictions, tax years subject to examination are 2013 through 2016, according to standard statute of limitations.
Asset Retirement Obligations
We record a liability for asset retirement obligations at the fair value of the estimated costs to retire a tangible long-lived asset at the time we incur that liability, which is generally when the asset is purchased, constructed or leased, when we have a legal obligation to incur costs to retire the asset and when a reasonable estimate of the fair value of the obligation can be made. If a reasonable estimate cannot be made at the time the liability is incurred, we record the liability when sufficient information is available to estimate the fair value.
We have asset retirement obligations with respect to certain of our assets due to various legal obligations to clean and/or dispose of those assets at the time they are retired. However, these assets can be used for an extended and indeterminate period of time as long as they are properly maintained and/or upgraded. It is our practice and current intent to maintain our assets and continue making improvements to those assets based on technological advances. As a result, we believe that our assets have indeterminate lives for purposes of estimating asset retirement obligations because dates or ranges of dates upon which we would retire these assets cannot reasonably be estimated at this time. When a date or range of dates can reasonably be estimated for the retirement of any asset, we estimate the costs of performing the retirement activities and record a liability for the fair value of these costs.

We also have legal obligations in the form of leases and right-of-way agreements, which require us to remove certain of our assets upon termination of the agreement. However, these lease or right-of-way agreements generally contain automatic renewal provisions that extend our rights indefinitely or we have other legal means available to extend our rights. We have recorded a liability of $0.7 million and $0.6 million as of December 31, 2017 and 2016 , respectively, which is included in “Other long-term liabilities” in the consolidated balance sheets, for conditional asset retirement obligations related to the retirement of terminal assets with lease and right-of-way agreements.
Environmental Remediation Costs
Environmental remediation costs are expensed and an associated accrual established when site restoration and environmental remediation and cleanup obligations are either known or considered probable and can be reasonably estimated. These environmental obligations are based on estimates of probable undiscounted future costs using currently available technology and applying current regulations, as well as our own internal environmental policies. The environmental liabilities have not been reduced by possible recoveries from third parties. Environmental costs include initial site surveys, costs for remediation and restoration and ongoing monitoring costs, as well as fines, damages and other costs, when estimable. Adjustments to initial estimates are recorded, from time to time, to reflect changing circumstances and estimates based upon additional information developed in subsequent periods.

11


NUSTAR ENERGY L.P. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)



Product Imbalances
We incur product imbalances as a result of variances in pipeline meter readings and volume fluctuations due to pressure and temperature changes. We use quoted market prices as of the reporting date to value our assets and liabilities related to product imbalances. Product imbalance liabilities are included in “Accrued liabilities” and product imbalance assets are included in “Other current assets” in the consolidated balance sheets.
Revenue Recognition
Revenues for the pipeline segment are derived from interstate and intrastate pipeline transportation of refined products, crude oil and anhydrous ammonia. Transportation revenues (based on pipeline tariffs) are recognized as the refined product, crude oil or anhydrous ammonia is delivered out of the pipelines.

Revenues for the storage segment include fees for tank storage agreements, whereby a customer agrees to pay for a certain amount of storage in a tank over a period of time (storage terminal revenues), and throughput agreements, whereby a customer pays a fee per barrel for volumes moving through our terminals (throughput terminal revenues). Our terminals also provide blending, additive injections, handling and filtering services for which we charge additional fees. Certain of our facilities charge fees to provide marine services such as pilotage, tug assistance, line handling, launch service, emergency response services and other ship services. Storage terminal revenues are recognized when services are provided to the customer. Throughput revenues are recognized as refined products or crude oil are received in or delivered out of our terminal. Revenues for marine services are recognized as those services are provided.
Revenues from the sale of petroleum products, which are included in our fuels marketing segment, are recognized when product is delivered to the customer and title and risk pass to the customer.
We collect taxes on certain revenue transactions to be remitted to governmental authorities, which may include sales, use, value-added and some excise taxes. These taxes are not included in revenue.
Income Allocation
Our partnership agreement, as amended, 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; however, losses are only allocated to the common 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.
Basic and Diluted Net Income Per Common Unit
Basic and diluted net income per common unit are 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.

We compute basic net income per common unit by dividing net income attributable to our common limited partners by the weighted-average number of common units outstanding during the period. We compute diluted net income per common unit by dividing net income attributable to our common limited partners by the sum of (i) the weighted-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 include contingently issuable performance units awarded under our long-term incentive plan. See Note 23 for additional information on our performance units.
Derivative Financial Instruments
We formally document all relationships between hedging instruments and hedged items. This process includes identification of the hedging instrument and the hedged transaction, the nature of the risk being hedged and how the hedging instrument’s effectiveness will be assessed. To qualify for hedge accounting, at inception of the hedge we assess whether the derivative instruments that are used in our hedging transactions are expected to be highly effective in offsetting changes in cash flows or the fair value of the hedged items. Throughout the designated hedge period and at least quarterly, we assess whether the derivative instruments are highly effective and continue to qualify for hedge accounting. To assess the effectiveness of the hedging relationship both prospectively and retrospectively, we use regression analysis to calculate the correlation of the changes in the fair values of the derivative instrument and related hedged item.

12


NUSTAR ENERGY L.P. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)



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 designated and qualifying as cash flow hedges (Cash Flow Hedges), we record the effective portion of mark-to-market adjustments as a component of accumulated other comprehensive income (loss) (AOCI) until the underlying hedged forecasted transactions occur. Any hedge ineffectiveness is recognized immediately in “Cost of product sales.” Once a hedged transaction occurs, we reclassify the effective portion from AOCI to “Cost of product sales.” If it becomes probable that a hedged transaction will not occur, then the associated gains or losses are reclassified from AOCI to “Cost of product sales” immediately. 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.”
Under the terms of our forward-starting interest rate swap agreements, we pay a fixed rate and receive a variable rate. We entered into the forward-starting 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. We account for the forward-starting interest rate swaps as Cash Flow Hedges, and we recognize the fair value of each interest rate swap in the consolidated balance sheets. We record the effective portion of mark-to-market adjustments as a component of AOCI, and any hedge ineffectiveness is recognized immediately in “Interest expense, net.” The amount accumulated in AOCI is amortized into “Interest expense, net” as the forecasted interest payments occur or if the interest payments are probable not to occur.
We classify cash flows associated with our derivative instruments as operating cash flows in the consolidated statements of cash flows, except for receipts or payments associated with terminated forward-starting interest rate swap agreements, which are included in cash flows from financing activities. See Note 16 for additional information regarding our derivative financial instruments.
Operating Leases
We recognize rent expense on a straight-line basis over the lease term, including the impact of both scheduled rent increases and free or reduced rents (commonly referred to as “rent holidays”).
Unit-based Compensation
Unit-based compensation for our long-term incentive plan is recorded in our consolidated balance sheets based on the fair value of the awards granted and recognized as compensation expense primarily on a straight-line basis over the requisite service period. Forfeitures of our unit-based compensation awards are recognized as an adjustment to compensation expense when they occur. Unit-based compensation expense is included in “General and administrative expenses” on our consolidated statements of income. See Note 23 for additional information regarding our unit-based compensation.
Margin Deposits
Margin deposits relate to our exchange-traded derivative contracts and generally vary based on changes in the value of the contracts. Margin deposits are included in “Other current assets” in the consolidated balance sheets.
Foreign Currency Translation
The functional currencies of our foreign subsidiaries are the local currencies of the countries in which the subsidiaries are located, except for our subsidiaries located in St. Eustatius in the Caribbean (formerly the Netherlands Antilles), whose functional currency is the U.S. dollar. The assets and liabilities of our foreign subsidiaries with local functional currencies are translated to U.S. dollars at period-end exchange rates, and income and expense items are translated to U.S. dollars at weighted-average exchange rates in effect during the period. These translation adjustments are included in “Accumulated other comprehensive loss” in the equity section of the consolidated balance sheets. Gains and losses on foreign currency transactions are included in “Other (expense) income, net” in the consolidated statements of income.

3. NEW ACCOUNTING PRONOUNCEMENTS

Derivatives and Hedging
In August 2017, 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 application of current hedge accounting guidance. 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 should be applied using a modified retrospective transition method. We currently expect to adopt the amended guidance on January 1, 2019. We do not

13


NUSTAR ENERGY L.P. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)



expect the guidance to have a material impact on our financial position or results of operations, and we are assessing the impact on our disclosures.

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. Under 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 adopted these provisions January 1, 2018, and the guidance did not have a material impact on our financial position, results of operations or disclosures.

Defined Benefit Plans
In March 2017, the FASB issued amended guidance that changes the presentation of net periodic pension cost related to defined benefit plans. Under the amended guidance, the service cost component of net periodic benefit cost will be presented in the same income statement line items as other current employee compensation costs, but the remaining components of net periodic benefit cost will be presented outside of operating income. The changes are effective for annual and interim periods beginning after December 15, 2017, and amendments should be applied retrospectively. We adopted these provisions January 1, 2018, and the guidance did not have a material impact on our financial position, results of operations or disclosures.

Goodwill
In January 2017, the FASB issued amended guidance that simplifies the accounting for goodwill impairment by eliminating step 2 of the goodwill impairment test. Under the amended guidance, goodwill impairment will be measured as the excess of the reporting unit’s carrying value over its fair value, not 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, and we are currently evaluating whether we will adopt these provisions early. Regardless of our decision, we do not expect the guidance to have 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 all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets, the set 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 adopted these provisions January 1, 2018, and they did not have an impact on our financial position, results of operations or disclosures.

Statement of Cash Flows
In August 2016, the FASB issued amended guidance that clarifies how entities should present certain cash receipts and cash payments on the statement of cash flows, including, but not limited to, debt prepayment or debt extinguishment costs, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims and distributions received from equity method investees. The changes are effective for annual and interim periods beginning after December 15, 2017, and amendments should be applied retrospectively. We adopted these provisions January 1, 2018, and they did not have an impact on our statements of cash flows or disclosures.

Credit Losses
In June 2016, the FASB issued amended guidance that requires the use of a “current expected loss” model for financial assets measured at amortized cost and certain off-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 recognize the assets and liabilities that arise from most leases on the balance sheet. For lessors, this amended guidance modifies the classification criteria and the accounting for sales-type and direct financing leases. The changes are effective for annual and interim periods beginning after December 15, 2018, and amendments should be applied using a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements, with the option to use certain expedients. In January 2018, the FASB issued additional guidance that provides an optional transition practical expedient for land easements. We currently expect to adopt these provisions on January 1, 2019 using the modified retrospective approach of adoption. We are working to identify our lease arrangements and have begun the process of system implementation. We are continuing to evaluate the impact of this amended guidance on our financial position, results of operations, disclosures and internal controls and plan to provide additional information about the expected financial impact at a future date.

Financial Instruments
In January 2016, the FASB issued new guidance that addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments. The changes are effective for annual and interim periods beginning after December 15, 2017, and amendments should be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. We adopted these provisions January 1, 2018, and they did not have an impact on our financial position, results of operations or disclosures.

Revenue Recognition
In May 2014, the FASB and the International Accounting Standards Board jointly issued a comprehensive new revenue recognition standard that requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration the entity expects to be entitled to in exchange for those goods or services. The standard is effective for public entities for annual and interim periods beginning after December 15, 2017 , using one of two retrospective transition methods. We adopted these provisions January 1, 2018 using the modified retrospective approach. The transition adjustment related to the adoption was immaterial (less than 1% of total revenues for the year ended December 31, 2017 and total partners’ equity as of December 31, 2017), and we do not expect the adoption of this standard to materially impact the amount or timing of our revenue going forward. Under the new guidance, we will no longer recognize the fair value of product imbalance assets or liabilities on our consolidated balance sheets. We intend to provide additional disclosures as required by the new standard, which we are currently assessing, in our quarterly report on Form 10-Q for the first quarter of 2018.

4. 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 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 12 and 19. 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 within the Central West System.

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.

(b)
The goodwill acquired represents the expected benefit from entering new geographic areas and the anticipated opportunities to generate future cash flows from the assets acquired and potential future projects.

The values used in the purchase price allocation above are preliminary and subject to change after we finalize our review of certain of Navigator’s pre-acquisition liabilities, and pending the completion of an independent appraisal. Although a change in the value used for the assets acquired and liabilities assumed would cause a corresponding increase or decrease in goodwill, we do not expect any change to be significant.

Martin Terminal Acquisition . On December 21, 2016 , we acquired crude oil and refined product storage assets in Corpus Christi, TX for $95.7 million , including $2.1 million of capital expenditure reimbursements, from Martin Operating Partnership L.P. (the Martin Terminal Acquisition). The assets acquired are in our storage segment and include 900,000 barrels of crude oil storage capacity, 250,000 barrels of refined product storage capacity and exclusive use of the Port of Corpus Christi’s new crude oil dock.

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

In connection with the Linden Acquisition, we ceased applying the equity method of accounting and consolidated Linden, which is included in our storage segment. The consolidated statements of income include the results of operations for Linden commencing on January 2, 2015. On the acquisition date, we remeasured our existing 50% equity investment in Linden to its fair value of $128.0 million and we recognized a gain of $56.3 million in “Other (expense) income, net” in the consolidated statement of income for the year ended December 31, 2015. We estimated the fair value using a market approach and an income approach. The market approach estimates the enterprise value based on an earnings multiple. The income approach calculates fair value by discounting the estimated net cash flows. We funded the acquisition with borrowings under our revolving credit agreement. The acquisition complements our existing storage operations, and having sole ownership of Linden strengthens our presence in the New York Harbor and the East Coast market.

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 a $110.0 million payment to us upon closing of the Axeon Sale. Therefore, we recorded a charge of $58.7 million , included in “Other (expense) income, net” in the consolidated statements of income, to reduce 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. Please refer to Note 15 for a discussion of the guarantees. In addition, in connection with the closing of the Axeon Sale, the terminal storage agreements that Axeon has with our Jacksonville, FL and Baltimore, MD terminal facilities were amended to increase the storage fees.

Prior to the closing of the Axeon Sale, we reviewed the financial information of Axeon monthly for possible credit loss indicators. We recognized interest income associated with the Axeon Term Loan ratably over the term of the loan in “Interest expense, net” on the consolidated statements of income.

We amortized an aggregate of $5.0 million , $4.4 million and $4.0 million of debt issuance costs and debt discount for the years ended December 31, 2017 , 2016 and 2015 , respectively.
Revolving Credit Agreement
On August 22, 2017, NuStar Logistics amended its revolving credit agreement (the Revolving Credit Agreement), mainly to extend the maturity date from October 29, 2019 to October 29, 2020 , and to increase the borrowing capacity from $1.50 billion to $1.75 billion . The Revolving Credit Agreement includes the ability to borrow up to the equivalent of $250.0 million in Euros and up to the equivalent of $250.0 million in British Pounds Sterling. Obligations under the Revolving Credit Agreement are guaranteed by NuStar Energy and NuPOP. For the year ended December 31, 2017 , we recorded deferred issuance costs of $3.1 million associated with the Revolving Credit Agreement to “Other long-term assets, net” on the consolidated balance sheet.

The Revolving Credit Agreement was also amended to increase the maximum allowed consolidated debt coverage ratio (as defined in the Revolving Credit Agreement) from 5.00-to-1.00 to 5.50-to-1.00 through the rolling period ending March 31, 2018. 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. On November 22, 2017, the Revolving Credit Agreement was amended to continue to exclude our $402.5 million fixed-to-floating rate subordinated notes from the definition of consolidated debt for purposes of calculating our consolidated debt coverage ratio

through December 31, 2018. The Revolving Credit Agreement also contains customary restrictive covenants, such as limitations on indebtedness, liens, mergers, asset transfers and certain investing activities.

The requirement not to exceed a maximum consolidated debt coverage ratio may limit the amount we can borrow under the Revolving Credit Agreement to an amount less than the total amount available for borrowing. As of December 31, 2017 , we had $853.0 million available for borrowing.
The Revolving Credit Agreement bears interest, at our option, based on an alternative base rate, a LIBOR-based rate or a EURIBOR-based rate. The interest rate on the Revolving Credit Agreement is subject to adjustment if our debt rating is downgraded (or upgraded) by certain credit rating agencies. As of December 31, 2017 , our weighted-average interest rate was 3.2% . During the year ended December 31, 2017 , the weighted-average interest rate related to borrowings under the Revolving Credit Agreement was 2.8% .
Letters of credit issued under the Revolving Credit Agreement totaled $3.7 million as of December 31, 2017 . Letters of credit are limited to $400.0 million (including up to the equivalent of $25.0 million in Euros and up to the equivalent of $25.0 million in British Pounds Sterling) and also may restrict the amount we can borrow under the Revolving Credit Agreement.
In February 2018, Moody’s Investor Service Inc. (Moody’s) lowered our credit rating from Ba1 to Ba2. This rating downgrade caused the interest rate on our Revolving Credit Agreement to increase by 0.25% effective February 2018.
Notes
NuStar Logistics 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. The 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.

Interest is payable semi-annually in arrears for the $350.0 million of 7.65% senior notes, $450.0 million of 4.80% senior notes, $300.0 million of 6.75% senior notes, $250.0 million of 4.75% senior notes and $550.0 million of 5.625% senior notes (collectively, the NuStar Logistics Senior Notes). The interest rate payable on the 7.65% senior notes is subject to adjustment if our debt rating is downgraded (or upgraded) by certain credit rating agencies and was 8.40% as of December 31, 2017 . In November 2017, Standard & Poor’s Rating Services lowered our credit rating from BB+ to BB. Additionally, the outlook was changed from stable to negative. The rating downgrade caused the interest rate on the 7.65% senior notes due 2018 to increase from 8.15% to 8.40% . The credit rating downgrade by Moody’s in February 2018 also increased the interest rate by 0.25% , resulting in an interest rate of 8.65% applicable to the interest payment due April 15, 2018.

The NuStar Logistics 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 and contain restrictions on NuStar Logistics’ ability to incur additional secured indebtedness unless the same security is also provided for the benefit of holders of the NuStar Logistics Senior Notes. In addition, the NuStar Logistics Senior Notes limit NuStar Logistics’ ability to incur indebtedness secured by certain liens and to engage in certain sale-leaseback transactions. At the option of NuStar Logistics, the NuStar Logistics Senior Notes may be redeemed in whole or in part at any time at a redemption price, which includes a make-whole premium, plus accrued and unpaid interest to the redemption date. If we undergo a change of control, as defined in the supplemental indentures for the 6.75% senior notes or the 5.625% senior notes, each holder of the 6.75% senior notes or the 5.625% senior 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 . The NuStar Logistics Senior Notes are fully and unconditionally guaranteed by NuStar Energy and NuPOP.
NuStar Logistics 7.625% Fixed-to-Floating Rate Subordinated Notes. NuStar Logistics’ $402.5 million of 7.625% fixed-to-floating rate subordinated notes are due January 15, 2043 (the Subordinated Notes). The Subordinated Notes are fully and unconditionally guaranteed on an unsecured and subordinated basis by NuStar Energy and NuPOP. The Subordinated Notes bore interest at a fixed annual rate of 7.625%, payable quarterly in arrears beginning on April 15, 2013 and ending on January 15, 2018. Thereafter, the Subordinated Notes bear interest at an annual rate equal to the sum of the three-month LIBOR rate for the related quarterly interest period, plus 6.734% payable quarterly, commencing April 15, 2018, unless payment is deferred in accordance with the terms of the notes. NuStar Logistics may elect to defer interest payments on the Subordinated Notes on one or more occasions for up to five consecutive years. Deferred interest will accumulate additional interest at a rate equal to the interest rate then applicable to the Subordinated Notes until paid. If NuStar Logistics elects to defer interest payments, NuStar Energy cannot declare or make cash distributions to its unitholders during the period that interest payments are deferred.

The Subordinated Notes do not have sinking fund requirements and are subordinated to existing senior unsecured indebtedness of NuStar Logistics and NuPOP. The Subordinated Notes do not contain restrictions on NuStar Logistics’ ability to incur additional indebtedness, including debt that ranks senior in priority of payment to the notes. In addition, the Subordinated Notes do not limit NuStar Logistics’ ability to incur indebtedness secured by liens or to engage in certain sale-leaseback transactions. Effective January 15, 2018, we may redeem the Subordinated Notes in whole or in part at a redemption price equal to 100% of the principal amount plus accrued and unpaid interest to the redemption date.
Gulf Opportunity Zone Revenue Bonds
In 2008, 2010 and 2011, the Parish of St. James, Louisiana issued Revenue Bonds Series 2008, Series 2010, Series 2010A, Series 2010B and Series 2011 associated with our St. James terminal expansions pursuant to the Gulf Opportunity Zone Act of 2005 for an aggregate $365.4 million (collectively, the GoZone Bonds). The interest rates on these bonds are based on a weekly tax-exempt bond market interest rate, and interest is paid monthly. Following the issuances, the proceeds were deposited with a trustee and are disbursed to us upon our request for reimbursement of expenditures related to our St. James terminal expansions. We include the amount remaining in the trust in “Other long-term assets, net,” and we include the amount of bonds issued in “Long-term debt” in our consolidated balance sheets. We did not receive any proceeds from the trustee for the year ended December 31, 2017 , and for the year ended December 31, 2016 , we received $12.5 million from the trustee.
NuStar Logistics is solely obligated to service the principal and interest payments associated with the GoZone Bonds. Letters of credit were issued by various individual banks on our behalf to guarantee the payment of interest and principal on the bonds. All letters of credit rank equally with existing senior unsecured indebtedness of NuStar Logistics. Obligations under the letters of credit issued are guaranteed by NuStar Energy and NuPOP. The letters of credit issued by individual banks do not restrict the amount we can borrow under the Revolving Credit Agreement.

Receivables Financing Agreement
NuStar Energy and NuStar Finance LLC (NuStar Finance), a special purpose entity and wholly owned subsidiary of NuStar Logistics, are parties to a $125.0 million receivables financing agreement with third-party lenders (the Receivables Financing Agreement) and agreements with certain of NuStar Energy’s wholly owned subsidiaries (collectively with the Receivables Financing Agreement, the Securitization Program). Under the Securitization Program, certain of NuStar Energy’s wholly owned subsidiaries (collectively, the Originators), sell their accounts receivable to NuStar Finance on an ongoing basis, and NuStar Finance provides the newly acquired accounts receivable as collateral for its revolving borrowings under the Receivables Financing Agreement. NuStar Energy provides a performance guarantee in connection with the Securitization Program. The maximum amount available for borrowing by NuStar Finance under the Receivables Financing Agreement is $125.0 million, with an option for NuStar Finance to request an increase of up to $75.0 million from the lenders (for aggregate total borrowings not to exceed $200.0 million). The amount available for borrowing is based on the availability of eligible receivables and other customary factors and conditions. The Securitization Program contains various customary affirmative and negative covenants and default, indemnification and termination provisions, and the Receivables Financing Agreement provides for acceleration of amounts owed upon the occurrence of certain specified events. NuStar Finance’s sole activity consists of purchasing such receivables and providing them as collateral under the Securitization Program. NuStar Finance is a separate legal entity and the assets of NuStar Finance, including these accounts receivable, are not available to satisfy the claims of creditors of NuStar Energy, the Originators or their affiliates.

NUSTAR ENERGY L.P. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)



On September 20, 2017, the Securitization Program was amended to add certain of NuStar Energy’s wholly owned subsidiaries resulting from the Navigator Acquisition and to extend the Securitization Program’s scheduled termination date from June 15, 2018 to September 20, 2020, with the option to renew for additional 364-day periods thereafter. Borrowings by NuStar Finance under the Receivables Financing Agreement bear interest at the applicable bank rate, as defined under the Receivables Financing Agreement. As of December 31, 2017 and 2016 , accounts receivable totaling $92.6 million and $104.5 million , respectively, were included in the Securitization Program. The weighted average interest rate related to outstanding borrowings under the Securitization Program during the year ended December 31, 2017 was 2.0% .

Short-Term Lines of Credit
NuStar Logistics is party to two short-term line of credit agreements with an aggregate uncommitted borrowing capacity of up to $85.0 million , which allow us to better manage fluctuations in our daily cash requirements and minimize our excess cash balances. The interest rate and maturity vary and are determined at the time of borrowing. We had $35.0 million outstanding under these lines of credit as of December 31, 2017 . Obligations under these short-term line of credit agreements are guaranteed by NuStar Energy. The weighted-average interest rate related to outstanding borrowings under our short-term lines of credit during the years ended December 31, 2017 and 2016 , was 2.7% and 2.0% , respectively.

13. HEALTH, SAFETY AND ENVIRONMENTAL MATTERS

Our operations are subject to extensive international, federal, state and local environmental laws and regulations, in the U.S. and in the other countries in which we operate, including those relating to the discharge of materials into the environment, waste management, remediation, the characteristics and composition of fuels, climate change and greenhouse gases. Our operations are also subject to extensive health, safety and security laws and regulations, including those relating to worker and pipeline safety, pipeline and storage tank integrity and operations security. The principal environmental, health, safety and security risks associated with our operations relate to unauthorized emissions into the air, releases into soil, surface water or groundwater, personal injury and property damage. We have adopted policies, practices, systems and procedures to comply with the laws and regulations, mitigate these risks, limit the liability that could result from such events, prevent material environmental or other damage, ensure the safety of our employees and the public and secure our pipelines, terminals and operations. Compliance with environmental, health, safety and security laws, regulations and related permits increases our capital expenditures and operating expenses, and violation of these laws, regulations or permits could result in significant civil and criminal liabilities, injunctions or other penalties.
Most of our pipelines are subject to federal regulation by one or more of the following governmental agencies: the Federal Energy Regulatory Commission (the FERC), the Surface Transportation Board (the STB), the Department of Transportation (DOT), the Environmental Protection Agency (EPA) and the Department of Homeland Security. Additionally, the operations and integrity of the pipelines are subject to the respective state jurisdictions along the routes of the systems.
We have adopted policies, practices and procedures to address pollution control, pipeline integrity, operator qualifications, public relations and education, process safety management, risk management planning, hazard communication, emergency response planning, community right-to-know, occupational health and the handling, storage, use and disposal of hazardous materials. Our policies are designed to comply with applicable federal, state and local regulations and to prevent material environmental or other damage, to ensure the safety of our pipelines, our employees, the public and the environment and to limit the financial liability that could result from such events. Future governmental action and regulatory initiatives could necessitate changes to expected operating permits and procedures, additional remedial actions or increased capital expenditures and operating costs. Risks of additional costs and liabilities are inherent within the industry, and there can be no assurances that significant costs and liabilities will not be incurred in the future.
Environmental and safety exposures and liabilities are difficult to assess and estimate due to unknown factors such as the timing and extent of remediation, the determination of our liability in proportion to other parties, improvements in cleanup technologies and the extent to which environmental and safety laws and regulations may change in the future. Although environmental and safety costs may have a significant impact on the results of operations for any single period, we believe that such costs will not have a material adverse effect on our financial position.

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. We accrued $7.3 million for contingent losses as of December 31, 2017 , and had no accrual for contingent losses as of December 31, 2016 . 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 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.

Rental expense for all operating leases totaled $36.2 million , $37.0 million and $39.7 million for the years ended December 31, 2017 , 2016 and 2015 , respectively. Our operating leases consist primarily of the following:
a ten-year lease for tugs and barges utilized at our St. Eustatius facility for bunker fuel sales, with two five-year renewal options ; and
land leases at various terminal facilities, with original terms ranging from 10 to 100 years.

Our purchase obligations primarily consist of an eleven-year chemical supply agreement related to our pipelines.

Lessor Revenues. We have entered into certain revenue arrangements where we are considered to be the lessor in accordance with GAAP. Under these arrangements we lease certain of our storage tanks in exchange for a fixed fee, subject to an annual consumer price index adjustment. The arrangements commenced on January 1, 2017, and have initial terms of ten years with successive  ten -year automatic renewal terms. We recognized $39.1 million of lease revenues from these leases for the year ended December 31, 2017 , which is included in “Service revenues” in the consolidated statements of income. Future minimum

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)



revenues we expect to receive under these lease arrangements as of December 31, 2017 total $352.2 million , which we will recognize ratably over the following nine years. As of December 31, 2017 , the cost and accumulated depreciation of leased storage assets totaled $229.8 million and $104.9 million , respectively.

15. 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 16 for a discussion of our derivative instruments.
Interest Rate Swaps. Because we estimate the fair value of our forward-starting interest rate swaps using discounted cash flows, which use observable inputs such as time to maturity and market interest rates, we include these interest rate swaps in Level 2 of the fair value hierarchy.

Guarantees. We previously provided guarantees for commodity purchases, lease obligations and certain utilities for Axeon. As of December 31, 2016 , we provided guarantees totaling $54.1 million , and one guarantee that did not specify a maximum amount. We estimated the fair value based on the guarantees outstanding and an estimate of the amount we would be obligated to pay under the guarantees at the time of default and considering the probability of default by Axeon. 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, our obligation to provide credit support to Axeon ceased. See Note 7 for additional information on the Axeon Term Loan.

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 the long-term debt, including the current portion, and the Axeon Term Loan were as follows:

We estimated the fair value of our publicly traded senior notes based upon quoted prices in active markets; therefore, we determined that the fair value of our publicly traded senior notes falls in Level 1 of the fair value hierarchy. For our other debt, for which a quoted market price is not available, we estimated the fair value using a discounted cash flow analysis using current incremental borrowing rates for similar types of borrowing arrangements and determined that the fair value falls in Level 2 of the fair value hierarchy. We determined that the fair value of the Axeon Term Loan approximated its carrying value as of December 31, 2016, which is included in “Other current assets” on the consolidated balance sheet. See Note 7 for additional information on the Axeon Term Loan.

16. DERIVATIVES AND RISK MANAGEMENT ACTIVITIES
We utilize various derivative instruments to manage our exposure to interest rate risk and commodity price risk. Our risk management policies and procedures are designed to monitor interest rates, futures and swap positions and over-the-counter positions, as well as physical volumes, grades, locations and delivery schedules, to help ensure that our hedging activities address our market risks.

Interest Rate Risk
We are a party to certain interest rate swap agreements to manage our exposure to changes in interest rates, which include forward-starting interest rate swap agreements related to forecasted debt issuances in 2018 and 2020. We entered into these swaps during the year ended December 31, 2015, 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 qualify as cash flow hedges, and we designate them as such. We record the effective portion of mark-to-market adjustments as a component of AOCI, and the amount in AOCI will be recognized in “Interest expense, net” as the forecasted interest payments occur or if the interest payments are probable not to occur. As of December 31, 2017 and 2016 , the aggregate notional amount of forward-starting interest rate swaps totaled $600.0 million .

The remaining fair value amount associated with unwound fixed-to-floating interest rate swap agreements totaled a $15.6 million and a $21.1 million gain as of December 31, 2017 and 2016 , respectively, and is included in “Long-term debt” on the consolidated balance sheets. The remaining fair value amount associated with unwound forward-starting interest rate swap agreements totaled a $14.3 million and a $20.9 million loss as of December 31, 2017 and 2016 , respectively, and is included in AOCI on the consolidated balance sheets. These amounts are amortized ratably over the remaining life of the related debt instrument into “Interest expense, net” on the consolidated statements of income.

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 or 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 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. 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 1.2 million barrels and 4.7 million barrels as of December 31, 2017 and 2016 , respectively. We had $0.3 million and $1.8 million of margin deposits as of December 31, 2017 and December 31, 2016 , respectively.

Please refer to Note 28 for a discussion of the merger of a subsidiary of ours with and into NuStar GP Holdings, pursuant to which we will become the sole member of NuStar GP Holdings.

GP Services Agreement. Prior to the Employee Transfer discussed in Note 1, our operations were managed by NuStar GP, LLC under a services agreement effective January 1, 2008 pursuant to which employees of NuStar GP, LLC performed services for our U.S. operations. Employees of NuStar GP, LLC provided services to us and NuStar GP Holdings; therefore, we reimbursed NuStar GP, LLC for all employee costs incurred prior to the Employee Transfer, other than the expenses allocated to NuStar GP Holdings.

In conjunction with the Employee Transfer, we entered into an Amended and Restated Services Agreement with NuStar GP, LLC, effective March 1, 2016 (the Amended GP Services Agreement). The Amended GP Services Agreement provides that we will furnish administrative services necessary to conduct the business of NuStar GP Holdings. NuStar GP Holdings will compensate us for these services through an annual fee of $1.0 million, subject to adjustment based on the annual merit increase percentage applicable to our employees for the most recently completed fiscal year and for changes in level of service. The Amended GP Services Agreement will terminate on March 1, 2020 and will automatically renew for successive two-year terms, unless terminated by either party.

Also on March 1, 2016 and in connection with the Employee Transfer, we entered into an Assignment and Assumption Agreement with NuStar GP, LLC (the Assignment Agreement). Under the Assignment Agreement, NuStar GP, LLC assigned all of its employee benefit plans, programs, contracts, policies, and various of its other agreements and contracts with certain employees, affiliates and third-party service providers (collectively, the Assigned Programs) to NuStar Services Co.

19. PARTNERS’ EQUITY

Please refer to Note 28 for a discussion of the merger of a subsidiary of ours with and into NuStar GP Holdings, pursuant to which we will become the sole member of NuStar GP Holdings.

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. The partnership agreement was amended and restated again in connection with the issuance of our Series C Preferred Units described below.

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.

During the year ended December 31, 2016 , we issued  595,050 common units representing limited partner interests at an average price of  $47.39  per unit for proceeds of  $28.3 million , net of $0.5 million of issuance costs. We used these proceeds, which include a contribution of  $0.6 million  from our general partner to maintain its 2% general partner interest, for general partnership purposes, including repayments of outstanding borrowings under the Revolving Credit Agreement.

For the years ended December 31, 2017 and 2016 , we issued 185,455 and 135,100 common units, respectively, representing limited partner interests in connection with the vestings of awards issued under our long-term incentive plan.

The Preferred Units rank equal to each other and senior to all of our other classes of equity securities with respect to distribution rights and rights upon liquidation.

We may redeem any of our outstanding Preferred Units at any time on or after the optional redemption date set forth above for each series of 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 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 Preferred Units, the preferred unitholders may have the ability to convert their Preferred Units to common units at the then applicable conversion rate. Holders of the Preferred Units have no voting rights except for certain exceptions set forth in our partnership agreement.

22. EMPLOYEE BENEFIT PLANS

Employee Transfer
On March 1, 2016, and in conjunction with the Employee Transfer, we assumed $22.5 million and $10.2 million in benefit obligations associated with the pension plans and other postretirement benefit plans, respectively. Prior to the Employee Transfer, we reimbursed all costs incurred by NuStar GP, LLC related to these employee benefit plans at cost. For comparability purposes this footnote presents information related to these benefit plans on a combined basis for periods prior to the Employee Transfer and after the Employee Transfer, including changes in the benefit obligation and fair value of plan assets, components of net periodic benefit cost (income), and adjustments to other comprehensive income (loss). Consequently, certain amounts presented below will differ from amounts reflected in our consolidated financial statements. See Note 17 for additional discussion on the Employee Transfer.

Thrift Plans
The NuStar Thrift Plan (the Thrift Plan) is a qualified defined contribution plan that became effective June 26, 2006. Participation in the Thrift Plan is voluntary and open to substantially all our domestic employees upon their dates of hire. Thrift Plan participants can contribute from 1% up to 30% of their total annual compensation to the Thrift Plan in the form of pre-tax and/or after tax employee contributions. We make matching contributions in an amount equal to 100% of each participant’s employee contributions up to a maximum of 6% of the participant’s total annual compensation. The matching contributions to the Thrift Plan for the years ended December 31, 2017 , 2016 and 2015 totaled $6.9 million , $6.6 million and $6.3 million , respectively.

The NuStar Excess Thrift Plan (the Excess Thrift Plan) is a nonqualified deferred compensation plan that became effective July 1, 2006. The Excess Thrift Plan provides benefits to those employees whose compensation and/or annual contributions under the Thrift Plan are subject to the limitations applicable to qualified retirement plans under the Code.

We also maintain several other defined contribution plans for certain international employees located in Canada, the Netherlands and the United Kingdom. For the years ended  December 31, 2017 , 2016 and 2015 , our costs for these plans totaled  $2.5 million $2.4 million  and  $2.6 million , respectively.

Pension and Other Postretirement Benefits
The NuStar Pension Plan (the Pension Plan) is a qualified non-contributory defined benefit pension plan that provides eligible U.S. employees with retirement income as calculated under a cash balance formula. Under the cash balance formula, benefits are determined based on age, service and interest credits, and employees become fully vested in their benefits upon attaining three years of vesting service. Prior to January 1, 2014, eligible employees were covered under either a cash balance formula or a final average pay formula (FAP). Effective January 1, 2014, the Pension Plan was amended to freeze the FAP benefits as of December 31, 2013, and going forward, all eligible employees are covered under the cash balance formula discussed above.
We also maintain an excess pension plan (the Excess Pension Plan), which is a nonqualified deferred compensation plan that provides benefits to a select group of management or other highly compensated employees. Neither the Excess Thrift Plan nor the Excess Pension Plan is intended to constitute either a qualified plan under the provisions of Section 401 of the Code or a funded plan subject to the Employee Retirement Income Security Act.

The Pension Plan and Excess Pension Plan are collectively referred to as the Pension Plans in the tables and discussion below. Our other postretirement benefit plans include a contributory medical benefits plan for U.S. employees that retired prior to April 1, 2014 and for employees that retire on or after April 1, 2014, a partial reimbursement for eligible third-party health care premiums. We use December 31 as the measurement date for our pension and other postretirement plans.

For the Pension Plan, since assets exceed the present value of expected benefit payments for the next 12 months, all of the liability is noncurrent. For the Excess Pension Plan and the other postretirement benefit plans, since there are no assets, the current liability is the present value of expected benefit payments for the next 12 months; the remainder is noncurrent.
The accumulated benefit obligation is the present value of benefits earned to date, assuming no future salary increases. The aggregate accumulated benefit obligation for our Pension Plans as of December 31, 2017 and 2016 was $146.3 million and $125.0 million , respectively. As of December 31, 2017 and 2016 , the aggregate accumulated benefit obligation for the Pension Plans exceeded plan assets.

Investment Policies and Strategies
The investment policies and strategies for the assets of our qualified Pension Plan incorporate a well-diversified approach that is expected to earn long-term returns from capital appreciation and a growing stream of current income. This approach recognizes that assets are exposed to risk, and the market value of the Pension Plan’s assets may fluctuate from year to year. Risk tolerance is determined based on our financial ability to withstand risk within the investment program and the willingness to accept return volatility. In line with the investment return objective and risk parameters, the Pension Plan’s mix of assets includes a diversified portfolio of equity and fixed-income instruments. The aggregate asset allocation is reviewed on an annual basis. As of December 31, 2017 , the target allocations for plan assets are 65% equity securities and 35% fixed income investments, with certain fluctuations permitted.

The overall expected long-term rate of return on plan assets for the Pension Plan is estimated using various models of asset returns. Model assumptions are derived using historical data with the assumption that capital markets are informationally efficient. Three models are used to derive the long-term expected returns for each asset class. Since each method has distinct advantages and disadvantages and differing results, an equal weighted average of the methods’ results is used.

Fair Value of Plan Assets
We disclose the fair value for each major class of plan assets in the Pension Plan 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.

Contributions to the Pension Plans
For the year ended December 31, 2017 , we contributed $11.1 million and $0.1 million to the Pension Plans and other postretirement benefit plans, respectively. During 2018 , we expect to contribute approximately $11.2 million and $0.4 million to the Pension Plans and other postretirement benefit plans, respectively, which principally represents contributions either required by regulations or laws, or with respect to unfunded plans, necessary to fund current benefits.

Assumed health care cost trend rates have a significant effect on the amounts reported for health care plans. We sponsor a contributory postretirement health care plan for employees that retired prior to April 1, 2014. The plan has an annual limitation (a cap) on the increase of the employer’s share of the cost of covered benefits. The cap on the increase in employer’s cost is 2.5% per year. The assumed increase in total health care cost exceeds the 2.5% indexed cap, so increasing or decreasing the health care cost trend rate by 1% does not materially change our obligation or expense for the postretirement health care plan.

23. UNIT-BASED COMPENSATION

Please refer to Note 28 for a discussion of the merger of a subsidiary of ours with and into NuStar GP Holdings, pursuant to which we will become the sole member of NuStar GP Holdings.

Overview
On January 28, 2016, our unitholders approved the Fifth Amended and Restated 2000 Long-Term Incentive Plan (the 2000 LTIP) which, among other items, provides that we may use newly issued common units from NuStar Energy to satisfy unit awards and extends the term of the 2000 LTIP to January 28, 2026. Prior to the Employee Transfer, NuStar GP, LLC sponsored the 2000 LTIP, and we reimbursed NuStar GP, LLC for awards under this plan. Following the approval of the 2000 LTIP and the Employee Transfer in 2016, most of our currently outstanding awards are now classified as equity awards as we intend to settle these awards through the issuance of our common units.

Effective March 1, 2016, we assumed sponsorship of the 2000 LTIP, which provides the Compensation Committee of the Board of Directors of NuStar GP, LLC (the Compensation Committee) with the right to issue and award up to 3,250,000 of our common units to employees and non-employee directors (NEDs). Awards available under the 2000 LTIP include restricted units, performance units, unit options, unit awards and distribution equivalent rights (DERs). The Compensation Committee may also include a tandem grant of a DER that will entitle the participant to receive cash equal to cash distributions made on

any award prior to its vesting. As of December 31, 2017 , common units that remained available to be awarded under the 2000 LTIP totaled 679,045 .

On March 1, 2016, we assumed all outstanding awards under the 2000 LTIP. The transfer of the outstanding awards qualifies as a plan modification. Therefore, we measured the fair value of the outstanding awards based on the common unit price on the transfer date.

Prior to the Employee Transfer, we reimbursed NuStar GP, LLC for our long-term incentive plan compensation expense which totaled $6.4 million for the year ended December 31, 2015.

Restricted Units
Our restricted unit awards are considered phantom units as they represent the right to receive our common units upon vesting.
We account for restricted units as either equity-classified awards or liability-classified awards depending on expected method of settlement. Awards we settle with the issuance of common units upon vesting are equity-classified. Awards we settle in cash upon vesting are liability-classified. We record compensation expense ratably over the vesting period based on the fair value of the common units at the grant date (for domestic employees) or the fair value of the common units measured at each reporting period (for NEDs and international employees). DERs paid with respect to outstanding equity-classified unvested restricted units reduce equity, similar to cash distributions to unitholders, whereas DERs paid with respect to outstanding liability-classified unvested restricted units are expensed. In connection with the DERs, we paid or expect to pay $3.0 million and $2.7 million , respectively, in cash, for the years ended December 31, 2017 and 2016 .

The total fair value of our equity-classified awards vested for the years ended December 31, 2017 and 2016 was  $6.5 million and $9.0 million , respectively. We issued 152,017 common units in connection with these award vestings, net of employee tax withholding requirements, for the year ended December 31, 2017 . Unrecognized compensation cost related to our equity-

classified employee awards totaled  $25.5 million  as of  December 31, 2017 , which we expect to recognize over a weighted-average period of 3.7 years.

Domestic Employees. The outstanding restricted units granted to domestic employees are equity-classified awards and generally vest over five years , beginning one year after the grant date. The fair value of these awards is measured at the transfer date (or grant date for issuances subsequent to the Employee Transfer).

Non-Employee Directors. The outstanding restricted units granted to NEDs are equity-classified awards that vest over three years . The fair value of these awards is equal to the market price of our common units at each reporting period.

International Employees. The outstanding restricted units granted to international employees are cash-settled and accounted for as liability-classified awards. These awards vest over three to five years and the fair value is equal to the market price of our common units at each reporting period.

Performance Units
Performance units are issued to certain of our key employees and represent rights to receive our common units upon achieving an objective performance measure for the performance period. The objective performance measure is determined each year by the NuStar GP, LLC Compensation Committee for the following year. Achievement of the performance measure determines the rate at which the performance units convert into our common units, which can range from zero to 200%.

Performance units vest in three annual increments (tranches), based upon our achievement of the performance measure set by the Compensation Committee during the one-year performance periods that end on December 31 of each year following the date of grant. Therefore, the performance units are not considered granted for accounting purposes until the Compensation Committee has set the performance measure for each tranche of awards. Performance units are equity-classified awards measured at the grant date fair value. In addition, since the performance units granted do not receive DERs, the grant date fair value of these awards is reduced by the per unit distributions expected to be paid to common unitholders during the vesting period. We record compensation expense ratably for each vesting tranche over its requisite service period (one year) if it is probable that the specified performance measure will be achieved. Additionally, changes in the actual or estimated outcomes that affect the quantity of performance units expected to be converted are recognized as a cumulative adjustment.

For the period from the Employee Transfer date to December 31, 2016, no performance units were granted or forfeited. For the year ended December 31, 2017 , we issued 33,438 common units in connection with the performance award vestings related to 2016 performance, net of employee tax withholding requirements. For 2017, we did not achieve the performance measure.

24. INCOME TAXES

On December 22, 2017, the U.S. enacted the Tax Cuts and Jobs Act (“the Act”). The Act, which is also commonly referred to as “U.S. tax reform,” significantly changes U.S. corporate income tax laws by, among other things, reducing the U.S. corporate tax rate from 35% to 21% , starting in 2018, and creating a territorial tax system with a one-time mandatory tax on previously deferred foreign earnings of U.S. subsidiaries. As a result, we recorded an expense of $0.8 million in the fourth quarter of 2017. This amount, which is included in “Income tax expense” on the consolidated statements of income, consists of two components: (i) $0.7 million relating to the one-time mandatory tax on previously deferred earnings of certain non-U.S. subsidiaries that are wholly owned by one of our U.S. subsidiaries and (ii) $0.1 million resulting from the revaluation of our net deferred tax assets in the U.S. based on the new lower corporate income tax rate.

Although the $0.8 million expense represents what we believe to be a reasonable estimate of the impact of the income tax effects of the Act on our consolidated financial statements as of December 31, 2017, it should be considered provisional. We are continuing to gather additional information to more precisely compute our deferred tax assets balance in the U.S., as well as the income tax expense associated with the one-time mandatory tax. Any adjustments to these provisional amounts will be reported as a component of “Income tax expense” on the consolidated statements of income in the reporting period in which any such adjustments are determined, which will be no later than the fourth quarter of 2018, and are not expected to be significant.

Due to the complexity of the new Global Intangible Low-Tax Income (GILTI) tax rules, we are continuing to evaluate this provision of the Act and the application of FASB’s Accounting Standards Codification 740 (ASC 740). Under U.S. GAAP, we are allowed to make an accounting policy choice of either (i) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current-period expense when incurred (the “period cost method”) or (ii) factoring such amounts into a company’s measurement of its deferred taxes (the “deferred method”). Our selection of an accounting policy with respect to the new GILTI tax rules will depend, in part, on analyzing our global income to determine whether we expect to have future U.S. inclusions in taxable income related to GILTI and, if so, what the impact is expected to be. Because whether we expect to have future U.S. inclusions in taxable income related to GILTI depends on not only our current structure and estimated future results of global operations, but also our intent and ability to modify our structure and/or our business, we are not yet able to reasonably estimate the effect of this provision of the Tax Act. Therefore, we have not made any adjustments related to potential GILTI tax in our consolidated financial statements as of December 31,2017, and have not made a policy decision regarding whether to record deferred taxes on GILTI.

Due to the complexity of the new Base Erosion Anti-Abuse Tax (BEAT) rules, we are continuing to evaluate this provision of the Act and the application of ASC 740. Under U.S. GAAP, because the BEAT provisions are designed to be an “incremental tax,” BEAT is treated as a current-period expense when incurred (the period cost method). Therefore, we have not made any adjustments related to the potential BEAT in our consolidated financial statements.
Components of income tax expense related to certain of our continuing operations conducted through separate taxable wholly owned corporate subsidiaries were as follows:

The difference between income tax expense recorded in our consolidated statements of income and income taxes computed by applying the statutory federal income tax rate ( 35% for all years presented) to income before income tax expense is due to the fact that the majority of our income is not subject to federal income tax due to our status as a limited partnership. We record a tax provision related to the amount of undistributed earnings of our foreign subsidiaries expected to be repatriated.

As of December 31, 2017 , our U.S. and foreign corporate operations have net operating loss carryforwards for tax purposes totaling $79.9 million and $13.1 million , respectively, which are subject to various limitations on use and expire in years 2025 through 2036 for U.S. losses and in years 2018 through 2026 for foreign losses.
As of December 31, 2017 and 2016 , we recorded a valuation allowance of $11.3 million and $12.8 million , respectively, related to our deferred tax assets. We estimate the amount of valuation allowance based upon our expectations of taxable income in the various jurisdictions in which we operate and the period over which we can utilize those future deductions. The valuation allowance reflects uncertainties related to our ability to utilize certain net operating loss carryforwards before they expire. In 2017 , there was a $1.9 million decrease in the valuation allowance for the U.S. net operating loss and a $0.4 million increase in the foreign net operating loss valuation allowance due to changes in our estimates of the amount of those loss carryforwards that will be realized, based upon future taxable income.
The realization of net deferred income tax assets recorded as of December 31, 2017 is dependent upon our ability to generate future taxable income in the United States. We believe it is more likely than not that the net deferred income tax assets as of December 31, 2017 will be realized, based on expected future taxable income.

25. SEGMENT INFORMATION

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

28. SUBSEQUENT EVENTS

On February 7, 2018, NuStar Energy, Riverwalk Logistics, L.P., NuStar GP, LLC, Marshall Merger Sub LLC, a wholly owned subsidiary of NuStar Energy (Merger Sub), Riverwalk Holdings, LLC and NuStar GP Holdings entered into an Agreement and Plan of Merger (the Merger Agreement) pursuant to which Merger Sub will merge with and into NuStar GP Holdings with NuStar GP Holdings being the surviving entity (the Merger), such that NuStar Energy will be the sole member of NuStar GP Holdings following the Merger. Pursuant to the Merger Agreement and at the effective time of the Merger, NuStar Energy’s partnership agreement will be amended and restated to, among other things, (i) cancel the incentive distribution rights held by our general partner, (ii) convert the 2% general partner interest in NuStar Energy held by our general partner into a non-economic management interest and (iii) provide the holders of our common units with voting rights in the election of the members of the board of directors of NuStar GP, LLC at an annual meeting, beginning in 2019.

At the effective time of the Merger, each outstanding NuStar GP Holdings common unit, other than those held by NuStar GP Holdings or its subsidiaries, will be converted into the right to receive 0.55 of a NuStar Energy common unit. All NuStar GP Holdings common units, when converted, will cease to be outstanding and will automatically be cancelled and no longer exist. No fractional NuStar Energy common units will be issued in the Merger; instead, each holder of NuStar GP Holdings’ common units otherwise entitled to receive a fractional NuStar Energy common unit will receive cash in lieu thereof. Furthermore, the 10,214,626 NuStar Energy common units currently owned by NuStar GP Holdings will be cancelled and will cease to exist.

At the effective time of the Merger, each outstanding award of NuStar GP Holdings restricted units will be converted, on the same terms and conditions as were applicable to the awards immediately prior to the Merger, into an award of NuStar Energy restricted units. The number of NuStar Energy restricted units subject to the converted awards will be determined as provided in the Merger Agreement. Each of our executive officers and directors has agreed and acknowledged that the Merger will not be deemed to trigger a “change of control” as defined under any NuStar Energy or NuStar GP Holdings plan or award, and has waived any rights to vesting, payment or other benefit thereunder that would arise upon a “change of control,” to which he or she might otherwise have been entitled.

The Merger Agreement contains customary representations and warranties and covenants by each of the parties. Completion of the Merger is conditioned upon, among other things: (i) approval of the Merger Agreement by the affirmative vote of holders of

NUSTAR ENERGY L.P. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)



a Unit Majority, as defined in the Second Amended and Restated Limited Liability Company Agreement of NuStar GP Holdings, as amended; (ii) the effectiveness of a registration statement on Form S-4 with respect to the issuance by NuStar Energy of its common units in connection with the Merger; (iii) the absence of certain legal injunctions or impediments prohibiting the transactions; (iv) the receipt of certain tax opinions from a nationally recognized tax counsel; and (v) the approval for the listing of NuStar Energy’s common units to be issued in the Merger on the New York Stock Exchange.

NuStar Energy entered into a Support Agreement, dated as of February 7, 2018 (the Support Agreement), with Merger Sub, WLG Holdings, LLC, a Texas limited liability company controlled by Mr. Greehey (WLG Holdings), Mr. Greehey (together, WLG Holdings and Mr. Greehey are referred to as the Greehey Unitholders), and, for limited purposes, NuStar GP Holdings, pursuant to which the Greehey Unitholders have agreed to vote in favor of the approval and adoption of the Merger Agreement, the approval of the Merger and any other action required in furtherance thereof submitted for the vote or written consent of NuStar GP Holdings unitholders. The Greehey Unitholders collectively own approximately 21% of the outstanding NuStar GP Holdings units. The Support Agreement will terminate (i) at the effective time of the Merger, (ii) upon the termination of the Merger Agreement as provided therein, or (iii) at such time as NuStar Energy and the Greehey Unitholders agree in writing to terminate the Support Agreement.

After the Merger, the NuStar GP, LLC board of directors is expected to consist of nine members, initially composed of the six members of the NuStar GP, LLC board of directors and the three independent directors of the board of directors of NuStar GP Holdings.

Additionally, on February 8, 2018, we announced that our management anticipates recommending to the board of directors of NuStar GP, LLC, and the board of directors expects to adopt, a reset of our quarterly distribution per common unit to $0.60 ( $2.40 on an annualized basis), starting with the first-quarter distribution payable in May 2018.
