[2]	On MayB 16, 2014, the 15,254,890 subordinated units were converted into common units on a one-for-one basis and thereafter participate on terms equal with all other common units in distributions of available cash. Distributions and the Partnershipbs net income were allocated to the subordinated units through MayB 15, 2014.

Organization and Basis of Presentation	'
	ORGANIZATION AND BASIS OF PRESENTATION
	As used in this report, the terms “Tesoro Logistics LP,” “TLLP,” the “Partnership,” “we,” “us,” or “our” refer to Tesoro Logistics LP, one or more of its consolidated subsidiaries or all of them taken as a whole. References in this report to “Tesoro” or our “Sponsor” refer collectively to Tesoro Corporation and any of its subsidiaries, other than Tesoro Logistics LP, its subsidiaries and its general partner.
	Organization
	TLLP is a Delaware limited partnership formed in December 2010 by Tesoro and its wholly owned subsidiary, Tesoro Logistics GP, LLC (“TLGP”), our general partner.
	In 2013, we entered into two transactions with Tesoro and TLGP, our general partner, pursuant to which TLLP acquired from Tesoro the following:
	•	six marketing terminals and storage facilities located in Southern California (the “Los Angeles Terminal Assets”) effective June 1, 2013; and
	•	two marine terminals, a marine storage facility, a products terminal, a petroleum coke handling and storage facility and crude oil and refined products pipelines located in Southern California (the “Los Angeles Logistics Assets”) effective December 6, 2013.
	These transactions are collectively referred to as “Acquisitions from Tesoro”.
	Principles of Combination and Consolidation and Basis of Presentation
	The Acquisitions from Tesoro were transfers between entities under common control. As an entity under common control with Tesoro, we record the assets that we acquire from Tesoro on our balance sheet at Tesoro’s historical basis instead of fair value. Transfers of businesses between entities under common control are accounted for as if the transfer occurred at the beginning of the period, and prior periods are retrospectively adjusted to furnish comparative information. Accordingly, the accompanying financial statements and related notes of TLLP have been retrospectively adjusted to include the historical results of the assets acquired in the Acquisitions from Tesoro for the three and six months ended June 30, 2013 with the exception of the Los Angeles Terminal Assets since they were not operated by Tesoro prior to their acquisition by TLLP. We refer to the historical results of the Los Angeles Logistics Assets, from June 1, 2013 to December 6, 2013, as our “Predecessor.”
	The accompanying financial statements and related notes include the combined results of operations and cash flows of our Predecessor at historical cost. The financial statements of our Predecessor have been prepared from the separate records maintained by Tesoro and may not necessarily be indicative of the conditions that would have existed or the results of operations if our Predecessor had been operated as an unaffiliated entity. Our Predecessor did not record revenue for transactions with Tesoro in the Terminalling and Transportation segment.
	The interim condensed combined consolidated financial statements and notes thereto have been prepared by management without audit according to the rules and regulations of the Securities and Exchange Commission (“SEC”) and reflect all adjustments that, in the opinion of management, are necessary for a fair presentation of results for the periods presented. Such adjustments are of a normal recurring nature, unless otherwise disclosed. All intercompany accounts and transactions have been eliminated.
	Certain information and notes normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted pursuant to the SEC’s rules and regulations. However, management believes that the disclosures presented herein are adequate to present the information fairly. The accompanying interim condensed combined consolidated financial statements and notes should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2013.
	We prepare our condensed combined consolidated financial statements in conformity with U.S. GAAP, which requires management to make estimates and assumptions that affect the amounts of assets and liabilities and revenues and expenses reported as of and during the periods presented. We review our estimates on an ongoing basis using currently available information. Changes in facts and circumstances may result in revised estimates, and actual results could differ from those estimates. The results of operations of the Partnership, or our Predecessor, for any interim period are not necessarily indicative of results for the full year.
	We believe the carrying value of our cash and cash equivalents, receivables, accounts payable and certain accrued liabilities approximates fair value. Our fair value assessment incorporates a variety of considerations, including:
	•	the short term duration of the instruments (none of our trade payables or trade receivables have been outstanding for greater than 90 days); and
	•	the expected future insignificance of bad debt expense, which includes an evaluation of counterparty credit risk.
	The fair value of our senior notes is based on prices from recent trade activity and is categorized in level 2 of the fair value hierarchy. The borrowings under our amended revolving credit facility (the “Revolving Credit Facility”), which include a variable interest rate, approximate fair value. The carrying value and fair value of our total debt were $1.4 billion and $1.5 billion, respectively, as of June 30, 2014, and were both approximately $1.2 billion as of December 31, 2013.
	New Accounting Standards
	Revenue Recognition
	The Financial Accounting Standards Board issued an Accounting Standards Update (“ASU”) in May 2014 which provides accounting guidance for all revenue arising from contracts to provide goods or services to customers. The requirements from the new ASU are effective for interim and annual periods beginning after December 15, 2016, and early adoption is not permitted. The standard allows for either full retrospective adoption or modified retrospective adoption. At this time, we are evaluating the guidance to determine the method of adoption and the impact of this ASU on our financial statements and related disclosures.

	ACQUISITIONS
	2014 Acquisition
	On June 23, 2014, we entered into an agreement with Tesoro to acquire certain terminalling and pipeline assets owned by Tesoro and two of its subsidiaries, Tesoro Refining & Marketing Company LLC and Tesoro Alaska Company LLC. Under the terms of the agreement, TLLP acquired three marketing terminals and a storage facility and will acquire a refined products pipeline (the “West Coast Logistics Assets”) for total consideration of $270.0 million. The operations of the West Coast Logistics Assets will be included in our Terminalling and Transportation segment.
	On July 1, 2014, we closed on the purchase of the first portion of the West Coast Logistics Assets in exchange for consideration of $241.4 million, comprised of approximately $214.4 million in cash and the issuance of equity to Tesoro with a fair value of $27.0 million. We borrowed $214.0 million on our Revolving Credit Facility on June 30, 2014, which was immediately distributed to TLGP to finance the transaction. This advance distribution to TLGP was recorded as a deposit in our condensed consolidated balance sheet as of June 30, 2014. The equity was comprised of 370,843 common units and 8,856 general partner units.
	The first portion of the West Coast Logistics Assets include:
	•	a truck terminal and six storage tanks, located in Nikiski, Alaska;
	•	a truck terminal, rail loading and unloading facility, and four storage tanks with a shell capacity of approximately 1.5 million barrels, all located at Tesoro’s refinery in Anacortes, Washington;
	•	a truck terminal and rail loading and unloading facility, all located at Tesoro’s refinery in Martinez, California; and
	•	certain related assets.
	We entered into throughput and use agreements with Tesoro for the marketing and storage terminal facilities in connection with the closing of this transaction. The terminalling agreement includes a minimum throughput commitment and the storage agreement requires Tesoro to pay a monthly storage services fee. See Note C for additional information regarding commercial agreements and amendments to other agreements with related parties in connection with the acquisition.
	TLLP expects to complete the second portion of this acquisition, upon receiving the required regulatory approval from the Regulatory Commission of Alaska, for cash consideration of $28.6 million. The remaining assets consist of all of Tesoro’s membership interests in Tesoro Alaska Pipeline Company LLC, a wholly-owned subsidiary of Tesoro, which owns a refined products pipeline connecting Tesoro’s Kenai refinery to Anchorage, Alaska.
	2013 Acquisitions
	Los Angeles Terminal and Los Angeles Logistics Asset Acquisitions
	We completed the Acquisitions from Tesoro in 2013 and entered into commercial agreements in connection with the acquisitions under which Tesoro commits to minimum monthly throughput volumes of crude oil and refined products. See our Annual Report on Form 10-K for the year ended December 31, 2013 for additional information regarding the Acquisitions from Tesoro and the commercial agreements executed in connection with these acquisitions.
	We have not provided disclosure of pro forma revenues and earnings as if the Acquisitions from Tesoro had occurred prior to 2013 for the three and six months ended June 30, 2013. BP managed and operated the Los Angeles Terminal Assets and the Los Angeles Logistics Assets as part of its refining operations, and historical U.S. GAAP financial information specific to the assets is not available. As a result, preparing pro forma information was determined to be impracticable.
	Northwest Products System Acquisition
	On June 19, 2013, we purchased a regulated common carrier products pipeline system running from Salt Lake City, Utah to Spokane, Washington (“Northwest Products Pipeline”) and three refined products terminals in Boise and Pocatello, Idaho and Pasco, Washington (collectively, the “Northwest Products System”) from Chevron Pipe Line Company and Northwest Terminalling Company (collectively, “Chevron”). The total purchase price was $354.8 million. During the second quarter of 2014, evaluations of the fair values related to the acquisition were completed and finalized. The purchase price allocation for the Northwest Products System acquisition is final and is based on estimated fair values of the assets acquired and liabilities assumed at the acquisition date. There were no material purchase price allocation adjustments recorded during the three and six months ended June 30, 2014.
	Pursuant to the regulatory review process associated with the Northwest Products System acquisition, we agreed to divest our legacy refined products terminal in Boise, Idaho (“Boise Terminal”). We completed the sale of the Boise Terminal on March 18, 2014. Net proceeds from the sale of the assets were $9.7 million, which resulted in a gain of $4.7 million recorded during the six months ended June 30, 2014.
	If the Northwest Products System acquisition had occurred prior to 2013, our pro forma revenues would have been $70.2 million and $133.5 million, respectively, for the three and six months ended June 30, 2013. Our pro forma net income would have been $14.8 million and $36.4 million, respectively, for the three and six months ended June 30, 2013.

Related-Party Transactions	'
	RELATED-PARTY TRANSACTIONS
	Affiliate Agreements
	The Partnership has various long-term, fee-based commercial agreements with Tesoro under which we provide pipeline transportation, trucking, terminal distribution, storage and petroleum-coke handling services and Tesoro commits to minimum monthly throughput volumes of crude oil and refined products. We believe the terms and conditions under these agreements are generally no less favorable to either party than those that could have been negotiated with unaffiliated parties with respect to similar services.
	We entered into or amended the following agreements with Tesoro in 2014:
	Terminalling Services Agreement - Nikiski. The Partnership entered into a ten-year master terminalling services agreement (the “Nikiski TSA”) with Tesoro at the closing of the first portion of the West Coast Logistics Assets acquisition on July 1, 2014. Tesoro has the option to extend the term for up to two renewal terms of five years each. Under the Nikiski TSA, Tesoro pays the Partnership fees for certain terminalling, storage and ancillary services at the Partnership’s Nikiski terminal, which was acquired as part of the first portion of the West Coast Logistics Assets acquisition.
	Terminalling Services Agreement - Anacortes. The Partnership entered into a ten-year master terminalling services agreement (the “Anacortes TSA”) with Tesoro at the closing of the first portion of the West Coast Logistics Assets acquisition on July 1, 2014. Tesoro has the option to extend the term for up to two renewal terms of five years each. Under the Anacortes TSA, Tesoro pays the Partnership fees for certain terminalling, storage and ancillary services at the Partnership’s Anacortes terminal, which was acquired as part of the first portion of the West Coast Logistics Assets acquisition.
	Terminalling Services Agreement - Martinez. The Partnership entered into a ten-year master terminalling services agreement (the “Martinez TSA”) with Tesoro at the closing of the first portion of the West Coast Logistics Assets acquisition on July 1, 2014. Tesoro has the option to extend the term for up to two renewal terms of five years each. Under the Martinez TSA, Tesoro pays the Partnership fees for certain terminalling, storage and ancillary services at the Partnership’s Martinez terminal, which was acquired as part of the first portion of the West Coast Logistics Assets acquisition.
	Storage Services Agreement - Anacortes. The Partnership entered into a ten-year storage services agreement (the “SSA”), with Tesoro with respect to crude and black oil Anacortes storage tanks, which were acquired as a part of the first portion of the West Coast Logistics Assets acquisition on July 1, 2014. Tesoro has the option to extend the term for up to two renewal terms of five years each. Under the SSA, Tesoro pays the Partnership fees for storage and handling services for crude oil, refinery feedstocks and refined products at the Anacortes terminal.
	Anacortes Truck Rack Construction Agreement. The Partnership entered into a construction service agreement (the “Construction Agreement”) with Tesoro on July 28, 2014. Under the Construction Agreement, effective July 1, 2014, the Partnership will pay Tesoro a fixed fee of $23.0 million for the construction of a new refined products distribution truck rack at the site of Partnership’s Anacortes terminal, which was acquired as part of the first portion of the West Coast Logistics Assets acquisition.
	Third Amended and Restated Omnibus Agreement. The Partnership entered into an omnibus agreement with Tesoro at the closing of our initial public offering (the “Initial Offering”). The agreement has been amended for each of the Acquisitions from Tesoro, and was most recently amended on July 1, 2014 in connection with the first portion of the West Coast Logistics Assets acquisition (the “Amended Omnibus Agreement”). In addition, the schedules to the Amended Omnibus Agreement were amended and restated, effective July 1, 2014, increasing the annual administrative fee payable by the Partnership to Tesoro under the Amended Omnibus Agreement from $5.5 million as of December 31, 2013 to $5.7 million as of July 1, 2014 for the provision of certain insurance coverage and various general and administrative services, including executive management, legal, accounting, treasury, human resources, health, safety and environmental, information technology, administration and other corporate services. In addition, the Partnership reimburses Tesoro for all other direct or allocated costs and expenses incurred by Tesoro or its affiliates on its behalf.
	Under the Amended Omnibus Agreement, Tesoro indemnifies us for certain matters, including environmental, title and tax matters associated with the ownership of our assets acquired from Tesoro, with the exception of the Los Angeles Terminal Assets acquisition and Los Angeles Logistics Assets acquisition, which are covered by the Carson Assets Indemnity Agreement (“Carson Assets Indemnity Agreement”). With respect to certain assets that we acquired from Tesoro, indemnification for unknown environmental and title liabilities is limited to pre-closing conditions identified prior to the earlier of the date that Tesoro no longer controls our general partner or five years after the date of closing. Under the Amended Omnibus Agreement, the aggregate annual deductible for each type of liability (unknown environmental liabilities or title matters) is $0.6 million, as of July 1, 2014.
	Secondment and Logistics Services Agreement. In connection with the acquisition of the first portion of the West Coast Logistics Assets on July 1, 2014, we terminated our Operational Services Agreement and entered into the Secondment and Logistics Services Agreement (the “Secondment Agreement”). Under the Secondment Agreement, employees of Tesoro are seconded to our general partner to provide operational and maintenance services for certain of our pipelines and terminals, and we reimburse our general partner for these costs. During their period of secondment, the seconded employees are under the management and supervision of our general partner. Conversely, employees of TLGP may be seconded to Tesoro to provide operational and maintenance services related to certain assets, for which Tesoro will reimburse our General Partner for the associated costs.

Net Income Per Unit	'
	NET INCOME PER UNIT
	We use the two-class method when calculating the net income per unit applicable to limited partners, because we have more than one participating security. At June 30, 2014, our participating securities consist of common units, general partner units and IDRs. Net income earned by the Partnership is allocated between the limited (both common and subordinated) and general partners in accordance with our partnership agreement. We base our calculation of net income per unit on the weighted average number of common and subordinated limited partner units outstanding during the period.
	Diluted net income per unit includes the effects of potentially dilutive units on our common units, which consist of unvested service and performance phantom units. Basic and diluted net income per unit applicable to subordinated limited partners are the same, as there are no potentially dilutive subordinated units outstanding. Distributions less than or greater than earnings are allocated in accordance with our partnership agreement.
	Following payment of the cash distribution for the first quarter of 2014 and the attainment of necessary approvals, the requirements for the conversion of all subordinated units were satisfied under the partnership agreement. As a result, effective May 16, 2014, the 15,254,890 subordinated units were converted into common units on a one-for-one basis and thereafter participate on terms equal with all other common units in distributions of available cash. The Partnership’s net income was allocated to the general partner and the limited partners, including the holders of the subordinated units through May 15, 2014, in accordance with our partnership agreement. The conversion did not impact the amount of the cash distribution paid or the total number of the Partnership’s outstanding units representing limited partner interests.

	____________
	(a)	General partner’s distributions (including IDRs) consist of an approximate 2% general partner interest and IDRs, which entitle the general partner to receive increasing percentages, up to 50%, of quarterly distributions in excess of $0.388125 per unit per quarter. See Note K of our Annual Report on Form 10-K for the year ended December 31, 2013 for further discussion related to IDRs.
	(b)	On May 16, 2014, the 15,254,890 subordinated units were converted into common units on a one-for-one basis and thereafter participate on terms equal with all other common units in distributions of available cash. Distributions and the Partnership’s net income were allocated to the subordinated units through May 15, 2014.
	(c)	We base our calculation of net income per unit on the weighted-average number of common and subordinated limited partner units outstanding during the period. Therefore, as a result of the public offering of common units in January 2013, and the conversion of the subordinated units to common units in May 2014, net income per common and subordinated limited partner units may not agree for the periods presented.

	____________
	(a) Includes unamortized premium of $5.3 million and $5.6 million as of June 30, 2014 and December 31, 2013, respectively.
	Revolving Credit Facility
	As of June 30, 2014, our Revolving Credit Facility provided for total loan availability of $575.0 million, and we are allowed to request that the loan availability be increased up to an aggregate of $650.0 million, subject to receiving increased commitments from the lenders. Our Revolving Credit Facility is non-recourse to Tesoro, except for TLGP, and is guaranteed by all of our subsidiaries and secured by substantially all of our assets. We had $227.6 million of borrowings and $0.3 million in letters of credit outstanding under the Revolving Credit Facility, resulting in a total unused loan availability of $347.1 million as of June 30, 2014. The weighted average interest rate for borrowings under our Revolving Credit Facility was 2.78% as of June 30, 2014. The Revolving Credit Facility is scheduled to mature on December 31, 2017.
	As of June 30, 2014, the Revolving Credit Facility was subject to the following expenses and fees:
	Credit Facility		30 day Eurodollar (LIBOR) Rate		Eurodollar Margin		Base Rate		Base Rate Margin	Commitment Fee
										(unused portion)
	TLLP Revolving Credit Facility (b)		0.16%		2.50%		3.25%		1.50%	0.50%
	____________
	(b) We have the option to elect if the borrowings will bear interest at either a base rate plus the base rate margin, or a Eurodollar rate, for the applicable period, plus the Eurodollar margin at the time of the borrowing. The applicable margin varies based upon a certain leverage ratio, as defined by the Revolving Credit Facility. We also incur commitment fees for the unused portion of the Revolving Credit Facility at an annual rate. Letters of credit outstanding under the Revolving Credit Facility incur fees at the Eurodollar margin rate.
	Exchange Offer
	The Partnership entered into a registration rights agreement (“Registration Rights Agreement”) in connection with the December 2013 private offering of $250.0 million of Senior Notes due 2020 (the “Unregistered Notes”). On July 25, 2014, the Partnership completed an offer to exchange the Unregistered Notes for notes registered under the Securities Act of 1933, as amended (the “Exchange Notes”). The terms of the Exchange Notes are identical in all material respects (including principal amount, interest rate, maturity and redemption rights) to the Unregistered Notes for which they were exchanged, except that the Exchange Notes generally are not subject to transfer restrictions. The exchange offer fulfills all of the requirements of the Registration Rights Agreement for the Unregistered Notes.
	Subsidiary Guarantors
	The parent company of the Partnership has no independent assets or operations. The Partnership’s operations are conducted by its wholly-owned guarantor subsidiaries, other than Tesoro Logistics Finance Corp., an indirect wholly-owned subsidiary of the Partnership whose sole purpose is to act as co-issuer of any debt securities. The guarantees are full and unconditional and joint and several, subject to certain automatic customary releases, including sale, disposition, or transfer of the capital stock or substantially all of the assets of a subsidiary guarantor, exercise of legal defeasance option or covenant defeasance option, and designation of a subsidiary guarantor as unrestricted in accordance with the applicable indenture. There are no significant restrictions on the ability of the Partnership or any guarantor to obtain funds from its subsidiaries by dividend or loan. None of the assets of the Partnership or a guarantor represent restricted net assets pursuant to Rule 4-08(e)(3) of Regulation S-X under the Securities Act.

	Indemnification
	Under the Amended Omnibus Agreement, Tesoro indemnifies us for certain matters, including environmental, title and tax matters associated with the ownership of our assets at or before the closing of the Initial Offering and subsequent acquisitions from Tesoro, excluding the Los Angeles Terminal Assets and the Los Angeles Logistics Assets. Under the Carson Assets Indemnity Agreement, Tesoro retained responsibility for remediation of known environmental liabilities due to the use or operation of the Los Angeles Terminal Assets and the Los Angeles Logistics Assets prior to the acquisition dates, and has indemnified the Partnership for any losses incurred by the Partnership arising out of those remediation obligations. See Note J of our Annual Report on Form 10-K for the year ended December 31, 2013 for additional information regarding the terms and conditions of the Amended Omnibus Agreement and the Carson Assets Indemnity Agreement.
	Environmental Liabilities
	We are subject to federal, state and local laws and regulations governing environmental quality and pollution control. These laws and regulations require us to remove or remedy the effect of the disposal or release of specified substances at current and former operating sites. We have accrued liabilities for these expenses and believe these accruals are adequate based on current information and projections that can be reasonably estimated. Our environmental accruals are based on estimates including engineering assessments, and it is possible that our projections will change and that additional costs will be recorded as more information becomes available. Our accruals for these environmental expenditures totaled $23.0 million and $24.4 million at June 30, 2014 and December 31, 2013, respectively. Changes in our environmental liabilities during the period were as follows (in thousands):
		Tioga Crude Oil Pipeline Release			Chevron Corrective Action Order			Other Liabilities			Total
	Balance at December 31, 2013	$	11,568		$	8,016		$	4,856		$	24,440
	Additions	5,636			—			571			6,207
	Expenditures	(2,122		)	(5,159		)	(325		)	(7,606		)
	Balance at June 30, 2014	$	15,082		$	2,857		$	5,102		$	23,041
	Tioga, North Dakota Crude Oil Pipeline Release
	In September 2013, the Partnership responded to the release of approximately 20,000 barrels of crude oil in a rural field northeast of Tioga, North Dakota (the “Crude Oil Pipeline Release”). The environmental liabilities related to the Crude Oil Pipeline Release include amounts estimated for remediation activities that will be conducted during the next few years to restore the site for agricultural use. We accrued an additional $5.6 million during the six months ended June 30, 2014 to reflect improved scope definition and estimates which resulted in an increase in the total estimated cost associated with the project. Probable insurance recoveries related to the Crude Oil Pipeline Release of $17.2 million and $14.0 million were included in other receivables at June 30, 2014 and December 31, 2013, respectively, pursuant to a pollution liability insurance policy, which is subject to a $1.0 million deductible and a $25.0 million loss limit. Through June 30, 2014, we have received insurance proceeds of $2.4 million in reimbursement of costs incurred.
	Costs to comply with a safety order related to the Crude Oil Pipeline Release issued by the Pipeline and Hazardous Materials Safety Administration of the U.S. Department of Transportation (“PHMSA”) are not expected to have a material adverse effect on our liquidity, financial position or results of operations.
	Chevron Diesel Pipeline Release
	On March 18, 2013, Chevron detected and responded to the release of diesel fuel (the “Diesel Pipeline Release”) that occurred near Willard, Utah on the Northwest Products System. As a result of this release, a Corrective Action Order (the “CAO”) was issued on March 22, 2013 by PHMSA. In addition, on April 11, 2013, the Department of Environmental Quality, Division of Water Quality, of the state of Utah issued a notice of violation and compliance order. In accordance with the sale and purchase agreements related to the Northwest Products System acquisition, as amended, Chevron retains financial and operational responsibility to remediate the site of the Diesel Pipeline Release through mid-2015, in addition to paying any monetary fines and penalties assessed by any government authority arising from this incident.
	The Partnership assumed responsibility for performing additional testing and associated pipeline repairs on the pipeline pursuant to the CAO upon closing the Northwest Products System acquisition. In connection with the Northwest Products System acquisition, our condensed consolidated balance sheet included $2.9 million and $8.0 million in accrued environmental liabilities related to the CAO at June 30, 2014 and December 31, 2013, respectively, and $4.9 million and $4.7 million in accruals unrelated to the Diesel Pipeline Release included in other noncurrent liabilities at June 30, 2014 and December 31, 2013, respectively.
	Contingencies
	In the ordinary course of business, we may become party to lawsuits, administrative proceedings and governmental investigations, including environmental, regulatory and other matters. The outcome of these matters cannot always be predicted accurately, but TLLP will accrue liabilities for these matters if the amount is probable and can be reasonably estimated. Other than described above, we did not have any material lawsuits, administrative proceedings or governmental investigations.

	EQUITY
	We had 35,350,338 common public units outstanding as of June 30, 2014. Additionally, Tesoro owned 19,110,714 of our common units and 1,110,282 of our general partner units (the 2% general partner interest) as of June 30, 2014, which together constitutes a 36% ownership interest in us.
	Following payment of the cash distribution for the first quarter of 2014 and the attainment of necessary approvals, the requirements for the conversion of all subordinated units were satisfied under the partnership agreement. As a result, effective May 16, 2014, 15,254,890 subordinated units were converted into common units on a one-for-one basis and thereafter participate on terms equal with all other common units in distributions of available cash. The conversion of the subordinated units did not impact the amount of cash distributions paid by the Partnership or the total number of its outstanding units.
	On June 25, 2014, we filed a prospectus supplement to our shelf registration statement filed with the SEC in 2012, authorizing the continuous issuance of up to an aggregate of $200.0 million of common units, in amounts, at prices and on terms to be determined by market conditions and other factors at the time of our offerings (such continuous offering program, or at-the-market program, referred to as our “ATM Program”). During the three months ended June 30, 2014, we issued an aggregate of 5,500 common units under our ATM Program, generating proceeds of approximately $0.4 million, net of offering costs. The net proceeds from these sales will be used for general partnership purposes. We paid fees of $7,903 related to the issuance of units under the ATM Program for the three months ended June 30, 2014. We issued an additional 193,900 common units under this program for net proceeds of $13.6 million (net of offering costs of $0.3 million) that settled in July 2014.

	Allocations of Net Income
	Our partnership agreement contains provisions for the allocation of net income and loss to the unitholders and the general partner. For purposes of maintaining partner capital accounts, the partnership agreement specifies that items of income and loss will be allocated among the partners in accordance with their respective percentage interest. Normal allocations according to percentage interests are made after giving effect, if any, to priority income allocations in an amount equal to incentive cash distributions fully allocated to the general partner.
	The following table presents the allocation of the general partner’s interest in net income (in thousands, except percentage of ownership interest):
		Three Months Ended June 30,							Six Months Ended June 30,

	SEGMENT DISCLOSURES
	Our revenues are derived from two operating segments: Crude Oil Gathering and Terminalling and Transportation. Our Crude Oil Gathering segment consists of a crude oil gathering system in the Bakken Shale/Williston Basin area of North Dakota and Montana. Our Terminalling and Transportation segment consists of:
	•	the Northwest Products Pipeline, which includes a regulated common carrier products pipeline running from Salt Lake City, Utah to Spokane, Washington and a jet fuel pipeline to the Salt Lake City International Airport;
	•	19 crude oil and refined products terminals and storage facilities in the western and midwestern U.S.;
	•	four marine terminals in California;
	•	a rail-car unloading facility in Washington;
	•	a petroleum coke handling and storage facility in Los Angeles; and
	•	other pipelines which transport products and crude oil from Tesoro’s refineries to nearby facilities in Salt Lake City and Los Angeles.
	Our revenues are generated from existing third-party contracts and from commercial agreements we have entered into with Tesoro under which Tesoro pays us fees for gathering crude oil and distributing, transporting and storing crude oil and refined products. We do not have any foreign operations.
	Our operating segments are strategic business units that offer different services. We evaluate the performance of each segment based on its respective operating income. Certain general and administrative expenses and interest and financing costs are excluded from segment operating income as they are not directly attributable to a specific operating segment. Identifiable assets are those used by the segment, whereas other assets are principally cash, deposits and other assets that are not associated with a specific operating segment.

New accounting pronouncement, policy	'
	Revenue Recognition
	The Financial Accounting Standards Board issued an Accounting Standards Update (“ASU”) in May 2014 which provides accounting guidance for all revenue arising from contracts to provide goods or services to customers. The requirements from the new ASU are effective for interim and annual periods beginning after December 15, 2016, and early adoption is not permitted. The standard allows for either full retrospective adoption or modified retrospective adoption. At this time, we are evaluating the guidance to determine the method of adoption and the impact of this ASU on our financial statements and related disclosures.

Net income per unit, policy	'
	We use the two-class method when calculating the net income per unit applicable to limited partners, because we have more than one participating security. At June 30, 2014, our participating securities consist of common units, general partner units and IDRs. Net income earned by the Partnership is allocated between the limited (both common and subordinated) and general partners in accordance with our partnership agreement. We base our calculation of net income per unit on the weighted average number of common and subordinated limited partner units outstanding during the period.

	(a)	General partner’s distributions (including IDRs) consist of an approximate 2% general partner interest and IDRs, which entitle the general partner to receive increasing percentages, up to 50%, of quarterly distributions in excess of $0.388125 per unit per quarter. See Note K of our Annual Report on Form 10-K for the year ended December 31, 2013 for further discussion related to IDRs.
	(b)	On May 16, 2014, the 15,254,890 subordinated units were converted into common units on a one-for-one basis and thereafter participate on terms equal with all other common units in distributions of available cash. Distributions and the Partnership’s net income were allocated to the subordinated units through May 15, 2014.
	(c)	We base our calculation of net income per unit on the weighted-average number of common and subordinated limited partner units outstanding during the period. Therefore, as a result of the public offering of common units in January 2013, and the conversion of the subordinated units to common units in May 2014, net income per common and subordinated limited partner units may not agree for the periods presented.

[1]	On MayB 16, 2014, the 15,254,890 subordinated units were converted into common units on a one-for-one basis and thereafter participate on terms equal with all other common units in distributions of available cash. Distributions and the Partnershipbs net income were allocated to the subordinated units through MayB 15, 2014.
[2]	We base our calculation of net income per unit on the weighted-average number of common and subordinated limited partner units outstanding during the period. Therefore, as a result of the public offering of common units in January 2013, and the conversion of the subordinated units to common units in May 2014, net income per common and subordinated limited partner units may not agree for the periods presented
[3]	General partnerbs distributions (including IDRs) consist of an approximate 2% general partner interest and IDRs, which entitle the general partner to receive increasing percentages, up to 50%, of quarterly distributions in excess of $0.388125 per unit per quarter. See Note K of our Annual Report on Form 10-K for the year ended DecemberB 31, 2013 for further discussion related to IDRs.

We also incur commitment fees for the unused portion of the Revolving Credit Facility at an annual rate. Letters of credit outstanding under the Revolving Credit Facility incur fees at the Eurodollar margin rate.
