Organization and Principles of Consolidation (Notes)	9 Months Ended
	Sep. 30, 2014
Organization, Consolidation and Presentation of Financial Statements [Abstract]	'
Organization and Principles of Consolidation	'
	Organization and Principles of Consolidation
	On April 27, 2014, Susser Holdings Corporation ("SUSS" or the "Parent") entered into an Agreement and Plan of Merger with Energy Transfer Partners, L.P. (“ETP”) and certain other related entities, under which ETP would acquire the outstanding common shares of SUSS ("ETP Merger"). This transaction was completed on August 29, 2014. By acquiring SUSS, ETP acquired 100.0% of the 0.0% non-economic general partner interest and incentive distribution rights in Susser Petroleum Partners LP ("SUSP"), and indirectly acquired approximately 11 million SUSP common and subordinated units (representing approximately 50.1% of SUSP’s outstanding units) as of August 29, 2014. Unvested phantom units that were outstanding on April 27, 2014 vested upon completion of the ETP Merger.
	Effective October 27, 2014, Susser Petroleum Partners LP (ticker symbol: SUSP) changed its name to Sunoco LP (ticker symbol: SUN). These changes align the Partnership's legal and marketing name with that of ETP's iconic brand, Sunoco. As used in this document, the terms "Partnership", "SUN", "we", "us" or "our", should be understood to refer to Sunoco LP including, prior to October 27, 2014, Susser Petroleum Partners LP.
	The consolidated financial statements are composed of Sunoco LP, a publicly traded Delaware limited partnership, and its consolidated subsidiaries, which distribute motor fuels in Texas, New Mexico, Oklahoma, Louisiana and Kansas. SUN was formed in June 2012 by SUSS and its wholly owned subsidiary, Sunoco GP LLC (formerly known as Susser Petroleum Partners GP LLC), our general partner. On September 25, 2012, we completed our initial public offering (“IPO”) of 10,925,000 common units representing limited partner interests.
	As a result of the ETP Merger, SUN became a consolidated entity of ETP and applied “push down” accounting that required its assets and liabilities to be adjusted to fair value on August 29, 2014. Due to the application of "push down" accounting, the SUN consolidated financial statements and certain footnote disclosures are presented in two distinct periods to indicate the application of two different bases of accounting between the periods presented. The periods prior to the acquisition date are identified as “Predecessor” and the period after the acquisition date is identified as “Successor”. For accounting purposes, management has designated the acquisition date as August 31, 2014, as the operating results and change in financial position for the intervening period is not material.
	Management, with the assistance of a third party valuation firm, has preliminarily estimated the fair value of its assets and liabilities as of the date of acquisition by ETP. The carrying values of SUN's assets and liabilities (excluding property and equipment, certain inventories, and intangibles) in this preliminary estimate were assumed to approximate their fair values. SUN’s identifiable intangible assets consist primarily of dealer relationships, the fair value of which were estimated by applying a discounted cash flow approach which was adjusted for customer attrition assumptions and projected market conditions. The amount of goodwill preliminarily recorded by SUN through “push down” accounting represents the excess of SUN's estimated enterprise value over the fair value of SUN’s assets and liabilities. As the valuation being performed by the third party valuation firm is not yet complete, the value of certain assets and liabilities are preliminary in nature, and are subject to adjustment as additional information is obtained about the facts and circumstances that existed at the acquisition date. As a result, material adjustments to this preliminary allocation may occur as the valuation and the related "push down" accounting is finalized in the future. The following table summarizes the preliminary allocation of the assets and liabilities of SUN.

	Other noncurrent liabilities		(252,523		)
	Total assets and liabilities		$	889,872
	The consolidated financial statements include the accounts of the Partnership and all of its subsidiaries. The Partnership currently operates in one operating segment, with primary operations conducted by the following consolidated wholly owned subsidiaries:
	•	Susser Petroleum Operating Company LLC, a Delaware limited liability company, distributes motor fuel to SUSS' retail and consignment locations, as well as third party customers in Texas, New Mexico, Oklahoma and Louisiana.
	•	T&C Wholesale LLC and Susser Energy Services LLC, both Texas limited liability companies, distribute motor fuels, propane and lubricating oils, primarily in Texas, Oklahoma and Kansas.
	•	Susser Petroleum Property Company LLC (“PropCo”), a Delaware limited liability company, primarily owns and leases convenience store properties.
	All significant intercompany accounts and transactions have been eliminated in consolidation.
	The Partnership also signed a definitive agreement on September 24, 2014, to acquire Honolulu, Hawaii-based Aloha Petroleum, Ltd ("Aloha").  Aloha is the largest independent gasoline marketer and one of the largest convenience store operators in Hawaii, with an extensive wholesale fuel distribution network and six fuel storage terminals on the islands.  Aloha currently markets through approximately 100 Shell, Aloha, and Mahalo branded fuel stations throughout the state, about half of which are company operated.  The base purchase price for Aloha is approximately $240 million in cash, subject to a post-closing earn-out, certain closing adjustments, and before transaction costs and expenses. The acquisition is expected to close in the fourth quarter of 2014 pending customary closing conditions.
	On September 25, 2014, the Partnership announced it had signed a definitive agreement to acquire Mid-Atlantic Convenience Stores, LLC from ETP. This transaction closed on October 1, 2014. See Note 15 for additional information.
	The consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. The interim consolidated financial statements have been prepared from the accounting records of the Partnership and its subsidiaries, and all amounts at September 30, 2014 and for the three and nine months ended September 30, 2013 and September 30, 2014, including the respective "Predecessor" and "Successor" periods, are unaudited. Pursuant to Regulation S-X, certain information and note disclosures normally included in the annual financial statements have been condensed or omitted. The information furnished reflects all adjustments which are, in the opinion of management, necessary for a fair statement of the results for the interim periods presented and which are of a normal, recurring nature other than the "push down" accounting.
	The consolidated financial statements and notes included herein should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2013 filed with the SEC on March 14, 2014.
	Certain line items have been reclassified for presentation purposes. In the fourth quarter of 2013, the Partnership revised its presentation of fuel taxes on motor fuel sales at its consignment locations to present such fuel taxes gross in motor fuel sales and motor fuel cost of sales to be consistent with its Parent's presentation of retail motor fuel sales. The effect of this immaterial error was to increase motor fuel sales and motor fuel cost of sales by $3.1 million and $15.1 million for the three and nine months ended September 30, 2013. This revision had no impact on gross margin, income from operations, net income and comprehensive income, or the balance sheets or statements of cash flows.

	FASB ASU No. 2014-09. In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers." This update establishes a core principal requiring revenue to be recognized in a manner to depict the transfer of goods or services to a customer at an amount that reflects the consideration expected to be received in exchange for those goods or services. This guidance is effective for annual reporting periods, and any interim periods within those annual periods, that begin after December 15, 2016 and allows for either full retrospective or modified retrospective application, with early adoption not permitted. The Partnership has not yet determined the adoption method it will apply and the impact that this guidance will have on its financial statements and related disclosures.
	FASB ASU No. 2013-11. In July 2013, the FASB issued ASU No. 2013-11, "Income Taxes - Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists- Subtopic 740-10." An unrecognized tax benefit, or a portion of an unrecognized tax benefit, shall be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The ASU was effective for annual and interim periods beginning after December 15, 2013. The adoption of this guidance did not have an impact on the presentation of our financial statements.

The impact of the change at September 30, 2014, was an increase of $0.8 million to fuel inventory. As the LIFO method is only permitted to be applied to year-end  inventory levels and costs, the application of interim LIFO adjustments are based on management’s estimates of expected year-end inventory levels and costs which are subject to the final year-end LIFO inventories valuation. In connection with the "push down" accounting discussed in Note 1, we recorded the inventory at fair value which was an immaterial change.

	Goodwill and Other Intangible Assets
	Goodwill is not amortized, but is tested annually for impairment, or more frequently if events and circumstances indicate that the asset might be impaired. The annual impairment test is performed as of the first day of the fourth quarter of the fiscal year. At December 31, 2013, and September 30, 2014, we had $22.8 million and $613.7 million, respectively, of goodwill recorded in conjunction with past business combinations including the purchase of SUSS by ETP on August 29, 2014. The increase of $590.9 million in the third quarter was recorded in conjunction with the ETP "push down" accounting discussed in Note 1. As of September 30, 2014, we evaluated potential impairment indicators and we believe no indicators of impairment occurred during the third quarter of 2014. As a result, no impairment was recorded to goodwill during the first nine months of 2014.
	The following table reflects goodwill activity for the nine months ended September 30, 2014 (in thousands):
	Balance at December 31, 2013	$	22,823
	Goodwill related to ETP "push down" accounting	590,899
	Balance at September 30, 2014	$	613,722
	The Partnership has finite‑lived intangible assets recorded that are amortized. The finite‑lived assets consist of supply agreements, favorable/unfavorable leasehold arrangements and loan origination costs, all of which are amortized over the respective lives of the agreements or over the period of time the assets are expected to contribute directly or indirectly to the Partnership's future cash flows. Customer relations, including supply agreements, are being amortized over a weighted-average period of approximately 20 years. Favorable/unfavorable leasehold arrangements are being amortized over an average period of approximately eight years. Loan origination costs are amortized over the life of the underlying debt as an increase to interest expense.
	During September 2014, the Partnership repaid its existing revolving credit facility and replaced it with a new revolving credit facility. Unamortized loan costs of $1.6 million relating to the existing facility were written off and loan costs of $7.6 million related to the new revolving credit facility were capitalized and are being amortized over the term of the new revolving credit facility.

	Term Loan and Security Agreement
	On September 25, 2012, in connection with the IPO, we entered into a Term Loan and Security Agreement (the "Term Loan") with Bank of America, N.A. for a $180.7 million term loan facility, expiring September 25, 2015. The Term Loan was repaid during the first quarter of 2014.
	Revolving Credit Agreement
	On September 25, 2012, we entered into a $250 million revolving credit agreement with a syndicate of banks (the “2012 Revolver”) expiring September 25, 2017. In December 2013, the 2012 Revolver commitments were increased by $150 million to a total of $400 million while retaining the ability to increase the 2012 Revolver by an additional $100 million. Borrowings under the revolving credit facility bore interest at (i) a base rate plus an applicable margin ranging from 1.00% to 2.25% or (ii) LIBOR plus an applicable margin ranging from 2.00% to 3.25%, (determined with reference to our consolidated total leverage ratio). In addition, the unused portion of the 2012 Revolver was subject to a commitment fee ranging from 0.375% to 0.50%, based on our consolidated total leverage ratio.
	On September 25, 2014, we entered into a new $1.25 billion revolving credit facility ("2014 Revolver" and, collectively with the 2012 Revolver, the "Revolver") with a syndicate of banks expiring September 25, 2019 (which date may be extended in accordance with the terms of the credit agreement). The 2014 Revolver includes an accordion feature thus providing flexibility to increase the facility by an additional $250 million, subject to certain conditions. Borrowings under the 2014 Revolver were used to repay and cancel the existing 2012 Revolver, of which $1.6 million in unamortized loan fees were fully amortized to interest expense.
	Borrowings under the 2014 Revolver will bear interest at a base rate (a rate based off of the higher of (a) the Federal Funds Rate (as defined therein) plus 0.5%, (b) Bank of America’s prime rate or (c) one-month LIBOR (as defined therein) plus 1.00%) or LIBOR, in each case plus an applicable margin ranging from 1.50% to 2.50%, in the case of a LIBOR loan, or from 0.50% to 1.50%, in the case of a base rate loan (determined with reference to the Partnership’s Leverage Ratio (as defined therein)). Upon the first achievement by the Partnership of an investment grade credit rating, the applicable margin will decrease to a range of 1.125% to 2.00%, in the case of a LIBOR loan, or from 0.125% to 1.00%, in the case of a base rate loan (determined with reference to the credit rating for the Partnership’s senior, unsecured, non-credit enhanced long-term debt). Interest is payable quarterly if the base rate applies, at the end of the applicable interest period if LIBOR applies and at the end of the month if daily floating LIBOR applies. In addition, the unused portion of the 2014 Revolver is subject to a commitment fee ranging from 0.250% to 0.350%, based on the Partnership’s Leverage Ratio (as defined therein). Upon the first achievement by the Partnership of an investment grade credit rating, the commitment fee will decrease to a range of 0.125% to 0.275%, based on the Partnership’s credit rating as described above.
	The 2014 Revolver requires the Partnership to maintain a Leverage Ratio of not more than 5.50 to 1.00. The maximum Leverage Ratio is subject to upwards adjustment of not more than 6.00 to 1.00 for a period not to exceed three fiscal quarters in the event the Partnership engages in an acquisition of assets, Equity Interests, (as defined therein) operating lines or divisions by the Partnership, a Subsidiary, (as defined therein) an Unrestricted Subsidiary (as defined therein) or a Joint Venture for a purchase price of not less than $50 million. Indebtedness under the 2014 Revolver is secured by a security interest in, among other things, all of the Partnership’s present and future personal property and all of the present and future personal property of its guarantors, the capital stock of its material subsidiaries (or 66% of the capital stock of material foreign subsidiaries), and any intercompany debt. Upon the first achievement by the Partnership of an investment grade credit rating, all security interests securing the 2014 Revolver will be released.
	As of September 30, 2014, the balance on the 2014 Revolver was $270.0 million and $10.9 million in standby letters of credit were outstanding. The unused availability on the 2014 Revolver at September 30, 2014 was $969.1 million. The Partnership was in compliance with all financial covenants at September 30, 2014.
	Guaranty by SUSS of Term Loan and 2012 Revolver/2014 Revolver
	SUSS entered into a Guaranty of Collection (the “Guaranty”) in connection with the Term Loan and the 2012 Revolver, which has been transferred to the 2014 Revolver. Pursuant to the Guaranty, SUSS guarantees the collection of the principal amount outstanding under (i) the Term Loan and (ii) the Revolvers. SUSS' obligation under the Guaranty is limited to $180.7 million. SUSS is not required to make payments under the Guaranty unless and until (a) the Partnership has failed to make a payment on such outstanding amounts, (b) the obligations under such facilities have been accelerated, (c) all remedies of the applicable lenders to collect the unpaid amounts due under such facilities, whether at law or equity, have been exhausted and (d) the applicable lenders have failed to collect the full amount owing on such facilities. In addition, SUSS entered into a Reimbursement Agreement with PropCo, whereby SUSS is obligated to reimburse PropCo for any amounts paid by PropCo under the guaranty of the Revolvers executed by the Partnership's subsidiaries.  SUSS' exposure under this reimbursement agreement is limited, when aggregated with its obligation under the Guaranty, to $180.7 million.
	Other Debt
	In August 2010 we entered into a mortgage note for an aggregate initial borrowing amount of $1.2 million. Pursuant to the terms of the mortgage note, we make monthly installment payments that are comprised of principal and interest through the maturity date of July 1, 2016. The balance outstanding at December 31, 2013 and September 30, 2014 was $1.1 million. The mortgage note bears interest at a fixed rate of 6.0%. The mortgage note is secured by a first priority security interest in a property owned by the Partnership.
	In September 2013, we assumed a $3.0 million term loan obligation from SUSS as part of the contribution of net assets of Gainesville Fuel business ("GFI Contribution").  The term loan had an outstanding balance of $2.5 million as of September 30, 2014 and bears a 4.0% fixed rate.
	The estimated fair value of long-term debt is calculated using Level 3 inputs. The fair value of debt as of September 30, 2014, is estimated to be approximately $272.9 million, based on the current balance of the 2014 Revolver and an analysis of the net present value of remaining payments on the other notes payable at a rate calculated off U.S. Treasury Securities.
	Fair Value Measurements
	We use fair value measurements to measure, among other items, purchased assets and investments, leases and derivative contracts. We also use them to assess impairment of properties, equipment, intangible assets and goodwill. Fair value is defined as the price at which an asset could be exchanged in a current transaction between knowledgeable, willing parties. A liability’s fair value is defined as the amount that would be paid to transfer the liability to a new obligor, not the amount that would be paid to settle the liability with the creditor. Where available, fair value is based on observable market prices or parameters, or is derived from such prices or parameters. Where observable prices or inputs are not available, use of unobservable prices or inputs is used to estimate the current fair value, often using an internal valuation model. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the item being valued.
	ASC 820 “Fair Value Measurements and Disclosures” prioritizes the inputs used in measuring fair value into the following hierarchy:
	Level 1	Quoted prices (unadjusted) in active markets for identical assets or liabilities;
	Level 2	Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable;
	Level 3	Unobservable inputs in which little or no market activity exists, therefore requiring an entity to develop its own assumptions about the assumptions that market participants would use in pricing.

	Income Tax
	As a limited partnership, we are generally not subject to state and federal income tax, with the exception of the state of Texas.  Included in our provision for income tax is a tax imposed by the state of Texas of 0.5% of gross margin in Texas (“franchise tax”). Our taxable income or loss, which may vary substantially from the net income or net loss reported in the Consolidated Statements of Operations and Comprehensive Income (Loss), is included in the federal and state income tax returns of each unitholder.  We are, however, subject to a statutory requirement that our non-qualifying income cannot exceed 10% of our total gross income, determined on a calendar year basis under the applicable income tax provisions. If the amount of our non-qualifying income exceeds this statutory limit, we would be taxed as a corporation. Accordingly, certain activities that generate non-qualifying income are conducted through a taxable corporate subsidiary, PropCo. PropCo is subject to federal and state income tax and pays any income taxes related to the results of its operations. For the year ended December 31, 2013, and the nine months ended September 30, 2014, our non-qualifying income did not exceed the statutory limit.

	Equity
	As of September 30, 2014, ETP indirectly owned 79,308 common units and 10,939,436 subordinated units, which together constituted a 50.1% ownership interest in us. As of September 30, 2014, the public owned 10,974,491 units. On October 1, 2014, 3,983,540 units were issued to ETP in connection with our acquisition of Mid-Atlantic Convenience Stores, LLC. For additional information, see Note 15.
	On October 27, 2014, we sold 8,000,000 common units to the public at a price of $46.25 per unit. We received net proceeds of $358.9 million, after deducting underwriting discounts and commissions, but before other offering expenses. For additional information see Note 15.
	Allocations of Net Income
	Our partnership agreement contains provisions for the allocation of net income and loss to the unitholders. For purposes of maintaining partner capital accounts, the partnership agreement specifies that items of income and loss shall 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 allocated 100% to ETP (prior to the ETP Merger, SUSS).
	The calculation of net income allocated to the partners is as follows (in thousands, except per unit amounts):

	Incentive Distribution Rights
	The following table illustrates the percentage allocations of available cash from operating surplus between our unitholders and ETP, (in its capacity as the holder of our incentive distribution rights or "IDRs") based on the specified target distribution levels. The amounts set forth under “marginal percentage interest in distributions” are the percentage interests of ETP (in its capacity as the holder of our IDRs) and the unitholders in any available cash from operating surplus we distribute up to and including the corresponding amount in the column “total quarterly distribution per unit target amount”. The percentage interests shown for our unitholders and ETP (in its capacity as the holder of our IDRs) for the minimum quarterly distribution are also applicable to quarterly distribution amounts that are less than the minimum quarterly distribution. The percentage interests set forth below for ETP (in its capacity as the holder of our IDRs) assume that there are no arrearages on common units and that ETP continues to own all of the IDRs.
				Marginal percentage interest in distributions

	Phantom Common Unit Awards
	During 2014, 6,354 phantom unit grants were issued. The fair value of each phantom unit on the grant date is equal to the market price of our common unit on that date reduced by the present value of estimated dividends over the vesting period, since the phantom units do not receive dividends until vested. The estimated fair value of our phantom units is amortized over the vesting period using the straight-line method. Non-employee director awards vest over a one-to-three-year period and employee awards vest ratably over a two-to-five-year service period. On August 29, 2014, effective with the ETP Merger, all outstanding unvested awards became fully vested. As a result, the Predecessor recorded equity-based compensation expense of $0.4 million primarily related to the accelerated vesting of these phantom common unit awards. As of September 30, 2014, there were no outstanding phantom common unit awards.
	A summary of our phantom unit award activity is set forth below:

Net Income Per Unit [Abstract]	'
Net Income per Unit	'
	Net Income (Loss) per Unit
	Net income (loss) per unit applicable to limited partners (including subordinated unitholders) is computed by dividing limited partners' interest in net income (loss), after deducting any incentive distributions, by the weighted-average number of outstanding common and subordinated units. Our net income (loss) is allocated to the limited partners in accordance with their respective partnership percentages, after giving effect to any priority income allocations for incentive distributions to SUSS (predecessor) and to ETP (successor), the holder of the IDRs, pursuant to our partnership agreement which are declared and paid following the close of each quarter. Earnings in excess of distributions are allocated to the limited partners based on their respective ownership interests. Payments made to our unitholders are determined in relation to actual distributions declared and are not based on the net income (loss) allocations used in the calculation of net income (loss) per unit.
	In addition to the common and subordinated units, we have also identified the IDRs as participating securities and use the two-class method when calculating the net income (loss) per unit applicable to limited partners, which is based on the weighted-average number of common units outstanding during the period. Diluted net income (loss) per unit includes the effects of potentially dilutive units on our common units to the extent such are anti-dilutive, consisting of nonvested phantom units. Basic and diluted net income (loss) per unit applicable to subordinated limited partners are the same because there are no potentially dilutive subordinated units outstanding.
	We also disclose limited partner units issued and outstanding. A reconciliation of the numerators and denominators of the basic and diluted per unit computations is as follows:

	We entered into two long-term, fee-based commercial agreements with SUSS in connection with our IPO, summarized as follows:
	•	Distribution contract - a 10-year agreement under which we are the exclusive distributor of motor fuel to SUSS' existing Stripes® convenience stores and independently operated consignment locations, and to all future sites purchased by the Partnership pursuant to the sale and leaseback option under the Omnibus Agreement, at cost, including tax and transportation costs, plus a fixed profit margin of approximately three cents per gallon. In addition, all future motor fuel volumes purchased by SUSS for its own account will be added to the distribution contract pursuant to the terms of the Omnibus Agreement.
	•	Transportation contract - a 10-year transportation logistics agreement, pursuant to which SUSS will arrange for motor fuel to be delivered from our suppliers to our customers at rates consistent with those charged by SUSS to third parties for the delivery of motor fuel.
	Omnibus Agreement
	In addition to the commercial agreements described above, we also entered into an Omnibus Agreement with SUSS pursuant to which, among other things, we received a three-year option to purchase from SUSS up to 75 of SUSS' new or recently constructed Stripes® convenience stores at their cost and lease the stores back to them at a specified rate for a 15-year initial term, and the Partnership will be the exclusive distributor of motor fuel to such stores for a period of ten years from the date of purchase. We also received a ten-year right to participate in acquisition opportunities with SUSS, to the extent the Partnership and SUSS are able to reach an agreement on terms, and the exclusive right to distribute motor fuel to certain of SUSS' newly constructed convenience stores and independently operated consignment locations. In addition, we agreed to reimburse our general partner and its affiliates for the costs incurred in managing and operating the Partnership. The Omnibus Agreement also provides for certain indemnification obligations between SUSS and the Partnership.

	On October 1, 2014, the Partnership acquired Mid-Atlantic Convenience Stores, LLC from ETP for a total consideration of approximately $768 million, subject to working capital adjustments.  The consideration paid by the Partnership consisted of 3,983,540 newly issued SUN common units and $556 million of cash. In connection with the acquisition, the Partnership obtained working capital of $75.3 million, property and equipment of $474.5 million, goodwill and other intangibles of $200.8 million and assumed certain indebtedness and other liabilities totaling $200.3 million. The Partnership initially financed the cash portion by utilizing availability under the 2014 Revolver and subsequently with proceeds from the offering discussed below.
	The assets owned by Mid-Atlantic Convenience Stores, LLC include the Mid-Atlantic Convenience Stores ("MACS") locations and the Tigermarket locations that were previously acquired by ETP.  Both businesses are currently operated and supplied by ETP's Sunoco subsidiary.
	The drop-down included approximately 110 company-operated retail convenience stores and 200 dealer-operated and consignment sites from the MACS/Tigermarket businesses. The combined portfolio includes locations in Virginia, Maryland, Tennessee and Georgia. This was the first transaction completed in a series of previously announced drop-down plans by which ETP would transfer its retail and fuel distribution business to the Partnership. For additional information, please refer to the Partnership's Form 8-K filed on September 25, 2014 and Form 8-K/A filed on October 21, 2014. The acquisition will be accounted for as an acquisition of net assets under common control. Specifically, the Partnership recognized the acquired assets and assumed liabilities at ETP's carrying value.
	If the purchase would have occurred on January 1, 2013, our combined revenue and net income would have been as follows:

	The Partnership announced on October 21, 2014, that it priced its registered underwritten public offering of 8 million common units representing limited partner interests, pursuant to an effective shelf registration statement on Form S-3 previously filed with the Securities and Exchange Commission (the "SEC") at $46.25 per common unit. The Partnership intends to use the net proceeds from the offering, including any net proceeds from the underwriters' exercise of their option to purchase additional common units, to repay indebtedness under its revolving credit facility and for general partnership purposes. This transaction closed on October 27, 2014.

	ASU No. 2014-09. In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers." This update establishes a core principal requiring revenue to be recognized in a manner to depict the transfer of goods or services to a customer at an amount that reflects the consideration expected to be received in exchange for those goods or services. This guidance is effective for annual reporting periods, and any interim periods within those annual periods, that begin after December 15, 2016 and allows for either full retrospective or modified retrospective application, with early adoption not permitted. The Partnership has not yet determined the adoption method it will apply and the impact that this guidance will have on its financial statements and related disclosures.
	FASB ASU No. 2013-11. In July 2013, the FASB issued ASU No. 2013-11, "Income Taxes - Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists- Subtopic 740-10." An unrecognized tax benefit, or a portion of an unrecognized tax benefit, shall be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The ASU was effective for annual and interim periods beginning after December 15, 2013. The adoption of this guidance did not have an impact on the presentation of our financial statements.
