	ORGANIZATION AND BASIS OF PRESENTATION
	Organization
	NuStar GP Holdings, LLC (NuStar GP Holdings) (NYSE: NSH) is a publicly held Delaware limited liability company. 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.
	We have no operations or sources of income or cash flows other than our investment in NuStar Energy L.P. (NuStar Energy) (NYSE: NS). As of June 30, 2014, 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
	•	10,253,584 common units of NuStar Energy representing a 12.9% limited partner interest.
	NuStar Energy is a publicly held Delaware limited partnership engaged in the transportation of petroleum products and anhydrous ammonia, the terminalling and storage of petroleum products and the marketing of petroleum products. 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.
	Basis of Presentation
	These unaudited condensed 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.
	We account for our ownership interest 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 in NuStar Energy. We have no separate operating activities apart from those conducted by NuStar Energy and therefore generate no revenues from operations.
	These unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities Exchange Act of 1934. Accordingly, they do not include all of the information and notes required by GAAP for complete consolidated financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included. All such adjustments are of a normal recurring nature unless otherwise indicated. Financial information for the three and six months ended June 30, 2014 and 2013 included in these Condensed Notes to Consolidated Financial Statements is derived from our unaudited condensed consolidated financial statements. Operating results for the three and six months ended June 30, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014. The consolidated balance sheet as of December 31, 2013 has been derived from the audited consolidated financial statements as of that date. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2013.
	New Accounting Pronouncement
	In May 2014, the Financial Accounting Standards Board and the International Accounting Standards Board jointly issued a comprehensive new revenue recognition standard. The standard is effective for public entities for annual and interim periods beginning after December 15, 2016, using one of two retrospective application methods. Early adoption is not permitted for public entities. We are currently assessing the impact of this new guidance on our financial statements and disclosures.

	GP Services Agreement. NuStar Energy and NuStar GP, LLC, our wholly owned subsidiary, entered into a services agreement, effective January 1, 2008 (the GP Services Agreement). The GP Services Agreement provides that NuStar GP, LLC will furnish administrative and certain operating services necessary to conduct the business of NuStar Energy. All employees providing services to both NuStar GP Holdings and NuStar Energy are employed by NuStar GP, LLC; therefore, NuStar Energy reimburses NuStar GP, LLC for all employee costs, other than the expenses allocated to NuStar GP Holdings (the Holdco Administrative Services Expense). The GP Services Agreement will terminate on December 31, 2014, renewing automatically every two years unless terminated by either party upon six months’ prior written notice. The aggregate amounts of Holdco Administrative Services Expense that we incurred were $0.4 million and $0.2 million for the three months ended June 30, 2014 and 2013, respectively, and $0.9 million and $0.6 million for the six months ended June 30, 2014 and 2013, respectively.
	Asphalt JV
	On February 26, 2014, NuStar Energy sold its remaining 50% ownership interest in NuStar Asphalt LLC (Asphalt JV) to Lindsay Goldberg LLC (Lindsay Goldberg), a private investment firm (the Asphalt JV Sale). Lindsay Goldberg now owns 100% of Asphalt JV. Effective February 27, 2014, NuStar Asphalt LLC changed its name to Axeon Specialty Products LLC. As a result of the Asphalt JV Sale, we ceased reporting transactions between us and Asphalt JV as related party transactions in consolidated financial statements on February 26, 2014.
	Asphalt JV Services Agreement. NuStar GP, LLC and Asphalt JV were a party to a services agreement, which provided that NuStar GP, LLC furnish certain administrative and other operating services necessary to conduct the business of Asphalt JV for an annual fee totaling $10.0 million, subject to adjustment (the Asphalt JV Services Agreement). The Asphalt JV Services Agreement terminated on June 30, 2014.

FAIR VALUE MEASUREMENTS	'
	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.
	The following liabilities are measured at fair value on a recurring basis:
		June 30, 2014
		Level 1			Level 2		Level 3		Total
		(Thousands of Dollars)
	Accrued compensation expense:

	NuStar Energy unit options	—			29		—		29
	Total	$	6,224		$	29	$	—	$	6,253
	The fair value of our accrued compensation expense for NuStar Energy restricted units and performance awards is determined using the NuStar Energy unit price at the reporting date. The fair value of our accrued compensation expense for NuStar Energy unit options is determined using the Black-Scholes option-pricing model on the reporting date based on the following weighted average assumptions:
		June 30,		December 31,
		2014		2013
	Expected life in years	5.9		5.8
	Expected volatility	26.7	%	26.4	%
	Expected distribution yield	7.1	%	8.6	%
	Risk-free interest rate	0.1	%	0.1	%
	Fair Value of Financial Instruments
	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 of our short-term debt would fall in Level 2 of the fair value hierarchy.

	CREDIT FACILITY
	Our revolving credit agreement dated June 28, 2013, as amended on June 17, 2014, will mature on June 27, 2015 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 June 30, 2014, 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 or a LIBOR-based rate. As of June 30, 2014, the weighted-average 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. As of June 30, 2014, NuStar Energy’s consolidated debt coverage ratio was 4.0x. 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 June 30, 2014.

	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.
