ORGANIZATION | ' | |
ORGANIZATION | ||
NuStar GP Holdings, LLC (NuStar GP Holdings) (NYSE: NSH), a publicly held Delaware limited liability company, was formed in June 2000. Unless otherwise indicated, the terms “NuStar GP Holdings,” “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 a unitholder. | ||
We have no operations or sources of income or cash flows other than our investment in NuStar Energy L.P. (NuStar Energy) (NYSE: NS). On December 31, 2013, we owned approximately 14.9% of NuStar Energy, consisting of the following: | ||
• | the 2% general partner interest; | |
• | 100% of the incentive distribution rights (IDR) 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 | |
• | 10,228,945 common units of NuStar Energy representing a 12.9% limited partner interest. | |
NuStar Energy is a publicly held Delaware limited partnership engaged in the terminalling and storage of petroleum products, the transportation of petroleum products and anhydrous ammonia, and the marketing of petroleum products. NuStar Energy has terminal and storage facilities in the United States, Canada, Mexico, the Netherlands, including St. Eustatius in the Caribbean, the United Kingdom and Turkey. |

Accounting Policies [Abstract] | ' |
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | ' |
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 their 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 14.9% investment in NuStar Energy using the equity method. As the general partner, we exercise significant influence over NuStar Energy, even though our ownership did not exceed 20% as of December 31, 2013. 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. We recognize a loss in the value of our investment that is other than a temporary decline currently in earnings 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, 2013 is recoverable. | |
Accounting for Sales 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. Please refer to Note 4 for a description of the issuances of common units by NuStar Energy. | |
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 2009 through 2012. | |
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, 2013 and 2012. | |
Unit-Based Compensation | |
We account for awards of NS unit options, performance awards and restricted units to employees and directors of NuStar GP, LLC at fair value, whereby a liability for the award is initially recorded and subsequent changes in the fair value are included in the determination of net income. The fair value of NS unit options is determined using the Black-Scholes model at each reporting date. The fair value of NS restricted units and performance awards equals the market price of NS common units at each reporting date. However, performance awards are earned only upon NuStar Energy’s achievement of an objective performance measure. We record compensation expense each reporting period such that the cumulative compensation expense equals the portion of the award’s current fair value that has vested. We record compensation expense related to NS unit options until such options are exercised, and we record compensation expense for NS restricted units and performance awards until the date of vesting. | |
We account for awards of NSH restricted units and unit options 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 unit options is determined using the Black-Scholes model at the grant date, and the fair value of the NSH restricted units equals the market price of NSH common units at the grant date. Compensation expense for NSH restricted units and unit options is recognized ratably over the vesting period based on the initial fair value determination. | |
The liability for awards of NS unit options, performance awards and restricted units is included in “Accrued compensation expense” on our consolidated balance sheets. NuStar Energy reimburses us for the expenses resulting from NS awards and NSH awards to employees providing services to NuStar Energy. Expenses resulting from NSH awards to our non-employee directors are included in “General and administrative expenses” on our consolidated statements of comprehensive income (loss). | |
Under these long-term incentive plans, certain awards provide that the grantee’s award vests immediately upon retirement. Compensation expense is recognized immediately if these awards are granted to retirement-eligible employees. In addition, if, during a vesting period of a grant, the grantee will become retirement-eligible, then compensation expense associated with the grant is recognized from the grant date through the grantee’s retirement eligibility date. Currently, employees are typically retirement eligible at age 55. | |
Pension and Other Postretirement Benefits | |
We recognize the overfunded or underfunded status of our defined benefit pension or postretirement plans as an asset or a liability as of the balance sheet dates. We record changes in the funded status of our plans as a component of comprehensive income (loss) in the year the changes occur. |

Other Comprehensive Income | |
In February 2013, the Financial Accounting Standards Board further amended the disclosure requirements for the presentation of comprehensive income. The amended guidance requires that entities present, either in a single note or parenthetically on the face of the financial statements, the effect of significant amounts reclassified from each component of accumulated other comprehensive income and the income statement line items affected by the reclassification. The amended guidance is effective prospectively for annual and interim reporting periods beginning after December 15, 2012. Accordingly, we adopted the amended guidance January 1, 2013, and it did not have a material impact on our disclosures. |

NuStar Energy’s Equity Offerings | ||||||||||||
On September 10, 2012, NuStar Energy issued 7,130,000 common units representing limited partner interests at a price of $48.94 per unit. NuStar Energy received proceeds of $336.8 million, net of issuance costs. In conjunction with NuStar Energy’s issuance of common units, we contributed $7.1 million to NuStar Energy in order to maintain our 2% general partner interest and our ownership in NuStar Energy was reduced from 16.3% at December 31, 2011 to 15.0% at December 31, 2012. This issuance resulted in a gain of $10.7 million for the year ended December 31, 2012, which is included in “Other income, net” on our consolidated statements of comprehensive income (loss), and represents the increase in the value of our proportionate share of NuStar Energy’s capital. | ||||||||||||
On December 9, 2011, NuStar Energy issued 6,037,500 common units representing limited partner interests at a price of $53.45 per unit. NuStar Energy received proceeds of $311.4 million, net of issuance costs. In September and October 2011, NuStar Energy issued 108,029 common units for proceeds of $5.9 million, net of issuance costs. In conjunction with NuStar Energy’s issuances of common units in 2011, we contributed $6.7 million to NuStar Energy in order to maintain our 2% general partner interest. Additionally, these issuances resulted in a gain of $8.1 million for the year ended December 31, 2011, which is included in “Other income, net” on our consolidated statements of comprehensive income and represents the increase in the value of our proportionate share of NuStar Energy’s capital. Following these issuances, our ownership in NuStar Energy was reduced from 17.6% at December 31, 2010 to 16.3% at December 31, 2011. | ||||||||||||
NuStar Energy’s Acquisitions and Dispositions | ||||||||||||
On January 1, 2013, NuStar Energy sold its fuels refinery in San Antonio, Texas (the San Antonio Refinery) and related assets, which included inventory, a terminal in Elmendorf, Texas and a pipeline connecting the terminal and refinery for approximately $117.0 million (the San Antonio Refinery Sale). NuStar Energy presented the results of operations for the San Antonio Refinery and related assets as discontinued operations for all periods presented. | ||||||||||||
On December 13, 2012, NuStar Energy completed its acquisition of the TexStar Crude Oil Assets (as defined below), including 100% of the partnership interest in TexStar Crude Oil Pipeline, LP, from TexStar Midstream Services, LP and certain of its affiliates (collectively, TexStar) for $325.4 million (the TexStar Asset Acquisition). The TexStar Crude Oil Assets consist of approximately 140 miles of crude oil pipelines and gathering lines, as well as five terminals and storage facilities providing 0.6 million barrels of storage capacity. | ||||||||||||
On September 28, 2012, NuStar Energy sold a 50% ownership interest (the Asphalt Sale) in NuStar Asphalt LLC (Asphalt JV), previously a wholly owned subsidiary of NuStar Energy. Asphalt JV owns and operates the asphalt refining assets that were previously wholly owned by NuStar Energy (collectively, the Asphalt Operations). Upon closing, NuStar Energy deconsolidated Asphalt JV and started reporting its remaining investment in Asphalt JV using the equity method of accounting. | ||||||||||||

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. | ||||||||||||

CREDIT FACILITY | ' |
CREDIT FACILITY | |
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 364-day revolving credit agreement dated June 28, 2013 matures on June 27, 2014 and has a borrowing capacity of up to $40.0 million, of which, up to $10.0 million may be available for letters of credit (the 2013 Credit Facility). Our obligations under the 2013 Credit Facility are guaranteed by Riverwalk Holdings, LLC (Riverwalk), a wholly owned subsidiary. Riverwalk pledged 1,792,918 NuStar Energy units that it owns to secure its guarantee. | |
As of December 31, 2013, we had outstanding borrowings of $26.0 million and availability of $14.0 million for borrowings under the 2013 Credit Facility. Interest on the 2013 Credit Facility is based upon, at our option, either an alternative base rate, plus 1.00% or a LIBOR-based rate, plus 2.00%. As of December 31, 2013, the interest rate was 2.2%. | |
The terms of the 2013 Credit Facility require NuStar Energy to maintain, as of the end of each rolling period, which consists of any period of four consecutive fiscal quarters, a consolidated debt coverage ratio not to exceed 5.0-to-1.0. If NuStar Energy consummates an acquisition for an aggregate net consideration of at least $50.0 million, the maximum consolidated debt coverage ratio will increase to 5.5-to-1.0 for two rolling periods. As of December 31, 2013, NuStar Energy’s consolidated debt coverage ratio was 4.4x. We are also required to receive cash distributions of at least $12.5 million in respect of our ownership interests in NuStar Energy each fiscal quarter. Our management believes that we are in compliance with the covenants of the 2013 Credit Facility as of December 31, 2013. | |
We borrowed $26.0 million under the 2013 Credit Facility during the year ended December 31, 2013, mainly to repay $18.5 million on our previous revolving credit facility and to repay $7.5 million to NuStar Energy for employee benefits and related costs. During the year ended December 31, 2013, our repayments totaled $20.0 million under the 2013 Credit Facility. The weighted-average interest rate related to borrowings under the 2013 Credit Facility for the year ended December 31, 2013 was 2.1%. |

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 ability to pay distributions. | |

The Rights become exercisable under specified circumstances, including if any person or group (an acquiring person) becomes the beneficial owner of 15% or more of our outstanding units, subject to specified exceptions. Each Right entitles the registered holder to purchase from us one one-hundredth of a unit of junior participating preferred units, series I (Preferred Units) at an exercise price of $100, subject to adjustment under specified circumstances. If events specified in the Rights Agreement occur, each holder of Rights other than the acquiring person can exercise their Rights. When a holder exercises a Right, the holder will be entitled to receive units valued at a multiple of the exercise price of the Right specified in the Rights Agreement. In some cases, the holder will receive cash, property or other securities instead of units. We may redeem the Rights for $0.001 per Right at any time prior to the tenth day after a person or group becomes an acquiring person. | |||||||||||||
The Rights will expire on June 30, 2016, unless extended or earlier redeemed or exchanged, and are protected by customary anti-dilution provisions. Preferred Units purchasable upon exercise of the Rights will not be redeemable. Each Preferred Unit will be entitled to share in our distributions of available cash pro rata with the units. In the event of liquidation, the holders of the Preferred Units will be entitled to a minimum preferential liquidation payment of $100 per unit. Each Preferred Unit will have 100 votes, voting together with the units. Finally, in the event of any merger, consolidation or other transaction in which units are exchanged, each Preferred Unit will be entitled to receive 100 times the amount received per unit. |

The NuStar Pension Plan (the Pension Plan) is a qualified non-contributory defined benefit pension plan that became effective July 1, 2006. The Pension Plan covers substantially all of NuStar GP, LLC’s employees and generally provides eligible employees with retirement income calculated under a final average pay formula (FAP) or a cash balance formula. Employees hired before January 1, 2011 are covered under FAP, which is based on years of service and compensation during their period of service, and employees become fully vested in their benefits upon attaining five years of vesting service. Employees hired on January 1, 2011 and after are covered under the cash balance formula, which is based on age, service and interest credits, and employees become fully vested in their benefits upon attaining three years of vesting service. Effective January 1, 2014, the Pension Plan was amended to freeze the FAP benefit as of December 31, 2013, and going forward, employees will be covered under the cash balance formula. | ||||||||||||||||||||||||
NuStar GP, LLC also maintains 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 of NuStar GP, LLC. The supplemental executive retirement plan (the SERP) has no participants, and it will terminate in 2014 upon a final payment to the former participants. | ||||||||||||||||||||||||
None of the Excess Thrift Plan, the Excess Pension Plan or the SERP 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. | ||||||||||||||||||||||||
NuStar GP, LLC also provides a medical benefits plan for retired employees. In 2013, the plan was amended for employees that retire on or after April 1, 2014 to provide a defined subsidy for eligible third-party health care premiums. | ||||||||||||||||||||||||
NuStar Energy reimbursed and will continue to reimburse all costs incurred by us related to these employee benefit plans at cost. We charged NuStar Energy $18.2 million, $23.6 million, and $13.7 million for the years ended December 31, 2013, 2012 and 2011, respectively, for these employee benefit plans, including disposition charges. Our current and noncurrent liabilities for these employee benefits are included in “Accrued compensation expense” and “Long-term liabilities,” respectively, on our consolidated balance sheets. | ||||||||||||||||||||||||
The Pension Plan, Excess Pension Plan and SERP are collectively referred to as the Pension Plans in the tables and discussion below. We use December 31 as the measurement date for our pension and other postretirement plans. | ||||||||||||||||||||||||
Effective January 1, 2013, Asphalt JV employees became employees of Asphalt JV and were 100% vested in the Pension Plan, as a result of the disposition. | ||||||||||||||||||||||||

In 2014, we expect to recognize $0.2 million and $0.1 million of the unrecognized actuarial loss for Pension Plans and other postretirement benefit plans, respectively. The aggregate accumulated benefit obligation for our Pension Plans as of December 31, 2013 and 2012 was $86.9 million and $84.6 million, respectively. As of December 31, 2013 and 2012, the aggregate accumulated benefit obligation for the Pension Plans exceeded plan assets. | ||||||||||||||||||||||||
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 NuStar Energy’s 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, 2013, the target allocations for plan assets are 65% equity securities and 35% fixed income investments. | ||||||||||||||||||||||||
The overall expected long-term rate of return on plan assets for the Pension Plan is estimated using 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. | ||||||||||||||||||||||||
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 in which little or no market data exists. | ||||||||||||||||||||||||

For the year ended December 31, 2013, we contributed $1.8 million to the Pension Plans. We expect to contribute approximately $4.3 million to the Pension Plans during 2014, which principally represents contributions either required by regulations or laws, or with respect to unfunded plans, necessary to fund current benefits. Since costs incurred by us related to the Pension Plan and our other postretirement benefit plan are reimbursed by NuStar Energy, funding for these plans will primarily be provided by NuStar Energy. | ||||||||||||||||||||||||

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. 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. |

Unit Options | ||||||||||||||||
Under the terms of our unit option plan, the exercise price of options granted is not less than the fair market value of our common units on the date of grant. Options become exercisable pursuant to the individual written agreements between the participants and us, usually in five equal annual installments beginning at the date of grant, with unexercised options expiring seven to ten years from the date of grant. | ||||||||||||||||
The fair value of each NSH unit option grant was estimated using the Black-Scholes option-pricing model on the grant date. The expected life of NSH unit options granted is the period of time from the grant date to the date of expected exercise or other expected settlement. Expected volatility for NSH unit options is based on closing prices of NSH common units for periods corresponding to the life of options granted. Expected distribution yield is based on annualized distributions at the grant date for NSH unit options. The risk-free interest rate used is the implied yield currently available from the U.S. Treasury zero-coupon issues with a remaining term equal to the expected life of the options at the grant date for NSH unit options. | ||||||||||||||||
On November 16, 2007, we granted 324,100 NSH unit options at $31.55, which was our only grant of options under the 2006 LTIP. These options expire seven years from the grant date and vest in annual one-third increments beginning on November 16, 2010. The total intrinsic value of unit options exercised during each of the years ended December 31, 2013 and December 31, 2012 was $0.1 million. As of December 31, 2013, the aggregate intrinsic value of NSH unit options outstanding and exercisable was zero as their market value at December 31, 2013 was less than their exercise price. The number of NSH unit options exercised during each of the years ended December 31, 2013 and 2012 was 11,666 and 11,667, respectively. No NSH unit options were exercised during the year ended December 31, 2011. The balance of NSH unit options outstanding was 289,100 and 300,766 as of December 31, 2013 and 2012, respectively. | ||||||||||||||||

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. | ||||||||||||

At December 31, 2013, our U.S. corporate operations had capital loss carryforwards for tax purposes, which were subject to a five-year carryforward limitation and were set to expire in 2017. The realization of deferred income tax assets recorded as of December 31, 2013 is dependent upon our ability to generate future taxable income in the United States. We believe that it is more-likely-than-not that the deferred tax assets as of December 31, 2013 will be realized, based upon expected future taxable income and potential tax planning strategies. |

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies) | 12 Months Ended |
Dec. 31, 2013 | |
Accounting Policies [Abstract] | ' |
Consolidation | ' |
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 | ' |
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 their estimates based on currently available information. Management may revise estimates due to changes in facts and circumstances. | |
Cash and Cash Equivalents | ' |
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 | ' |
Investment in NuStar Energy | |
We account for our 14.9% investment in NuStar Energy using the equity method. As the general partner, we exercise significant influence over NuStar Energy, even though our ownership did not exceed 20% as of December 31, 2013. 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. We recognize a loss in the value of our investment that is other than a temporary decline currently in earnings 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, 2013 is recoverable. | |
Accounting for Sales of Units by NuStar Energy | ' |
Accounting for Sales 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. Please refer to Note 4 for a description of the issuances of common units by NuStar Energy. | |
Income Taxes | ' |
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 2009 through 2012. | |
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, 2013 and 2012. | |
Unit-Based Compensation | ' |
Unit-Based Compensation | |
We account for awards of NS unit options, performance awards and restricted units to employees and directors of NuStar GP, LLC at fair value, whereby a liability for the award is initially recorded and subsequent changes in the fair value are included in the determination of net income. The fair value of NS unit options is determined using the Black-Scholes model at each reporting date. The fair value of NS restricted units and performance awards equals the market price of NS common units at each reporting date. However, performance awards are earned only upon NuStar Energy’s achievement of an objective performance measure. We record compensation expense each reporting period such that the cumulative compensation expense equals the portion of the award’s current fair value that has vested. We record compensation expense related to NS unit options until such options are exercised, and we record compensation expense for NS restricted units and performance awards until the date of vesting. | |
We account for awards of NSH restricted units and unit options 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 unit options is determined using the Black-Scholes model at the grant date, and the fair value of the NSH restricted units equals the market price of NSH common units at the grant date. Compensation expense for NSH restricted units and unit options is recognized ratably over the vesting period based on the initial fair value determination. | |
The liability for awards of NS unit options, performance awards and restricted units is included in “Accrued compensation expense” on our consolidated balance sheets. NuStar Energy reimburses us for the expenses resulting from NS awards and NSH awards to employees providing services to NuStar Energy. Expenses resulting from NSH awards to our non-employee directors are included in “General and administrative expenses” on our consolidated statements of comprehensive income (loss). | |
Under these long-term incentive plans, certain awards provide that the grantee’s award vests immediately upon retirement. Compensation expense is recognized immediately if these awards are granted to retirement-eligible employees. In addition, if, during a vesting period of a grant, the grantee will become retirement-eligible, then compensation expense associated with the grant is recognized from the grant date through the grantee’s retirement eligibility date. Currently, employees are typically retirement eligible at age 55. | |
Pension and Other Postretirement Benefits | ' |
Pension and Other Postretirement Benefits | |
We recognize the overfunded or underfunded status of our defined benefit pension or postretirement plans as an asset or a liability as of the balance sheet dates. We record changes in the funded status of our plans as a component of comprehensive income (loss) in the year the changes occur. |

Rights Agreement, Description | 'On JulyB 19, 2006, we entered into a rights agreement with Computershare Investor Services, LLC, as amended effective February 28, 2008 and October 23, 2012 (the Rights Agreement), under which one preferred unit purchase right (a Right) is attached to each of our outstanding units. The Rights become exercisable under specified circumstances, including if any person or group (an acquiring person) becomes the beneficial owner of 15% or more of our outstanding units, subject to specified exceptions. Each Right entitles the registered holder to purchase from us one one-hundredth of a unit of junior participating preferred units, seriesB I (Preferred Units) at an exercise price of $100, subject to adjustment under specified circumstances. If events specified in the Rights Agreement occur, each holder of Rights other than the acquiring person can exercise their Rights. When a holder exercises a Right, the holder will be entitled to receive units valued at a multiple of the exercise price of the Right specified in the Rights Agreement. In some cases, the holder will receive cash, property or other securities instead of units. We may redeem the Rights for $0.001 per Right at any time prior to the tenth day after a person or group becomes an acquiring person. The Rights will expire on JuneB 30, 2016, unless extended or earlier redeemed or exchanged, and are protected by customary anti-dilution provisions. Preferred Units purchasable upon exercise of the Rights will not be redeemable. Each Preferred Unit will be entitled to share in our distributions of available cash pro rata with the units. In the event of liquidation, the holders of the Preferred Units will be entitled to a minimum preferential liquidation payment of $100 per unit. Each Preferred Unit will have 100 votes, voting together with the units. Finally, in the event of any merger, consolidation or other transaction in which units are exchanged, each Preferred Unit will be entitled to receive 100 times the amount received per unit. |

Defined Benefit Plan, Description | 'The NuStar Pension Plan (the Pension Plan) is a qualified non-contributory defined benefit pension plan that became effective JulyB 1, 2006. The Pension Plan covers substantially all of NuStar GP, LLCbs employees and generally provides eligible employees with retirement income calculated under a final average pay formula (FAP) or a cash balance formula. Employees hired before January 1, 2011 are covered under FAP, which is based on years of service and compensation during their period of service, and employees become fully vested in their benefits upon attaining five years of vesting service. Employees hired on January 1, 2011 and after are covered under the cash balance formula, which is based on age, service and interest credits, and employees become fully vested in their benefits upon attaining three years of vesting service. Effective January 1, 2014, the Pension Plan was amended to freeze the FAP benefit as of December 31, 2013, and going forward, employees will be covered under the cash balance formula. | ' | ' |
