SUNOCO LOGISTICS PARTNERS L.P.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

1. Organization and Basis of Presentation

Sunoco Logistics Partners L.P. (the "Partnership") is a publicly traded Delaware limited partnership that owns and operates a logistics business, consisting of crude oil, refined products and natural gas liquids ("NGL") pipelines, terminalling and storage assets, and crude oil, refined products and NGL acquisition and marketing assets. The Partnership conducts its business activities in 35 states located throughout the United States.

The condensed consolidated financial statements reflect the results of the Partnership and its wholly owned subsidiaries, including Sunoco Logistics Partners Operations L.P. (the "Operating Partnership"), the proportionate shares of the Partnership's undivided interests in assets, and the accounts of entities in which the Partnership has a controlling financial interest. The Partnership's controlling financial interests are attributed to voting interests greater than 50 percent. The Partnership holds a controlling financial interest in Inland Corporation ("Inland"), Mid-Valley Pipeline Company ("Mid-Valley"), West Texas Gulf Pipe Line Company ("West Texas Gulf") and Price River Terminal, LLC ("PRT"), which was acquired in the second quarter 2014 (Note 3), and as such, these entities are reflected as consolidated subsidiaries of the Partnership. The Partnership is not the primary beneficiary of any variable-interest entities ("VIEs"). All significant intercompany accounts and transactions are eliminated in consolidation, and noncontrolling interests in net income and equity are shown separately in the condensed consolidated statements of comprehensive income and balance sheets, respectively. Equity ownership interests in corporate joint ventures in which the Partnership does not have a controlling financial interest, but over which the Partnership can exercise significant influence, or VIEs in which the Partnership has a variable interest but of which the Partnership is not the primary beneficiary, are accounted for under the equity method of accounting.

In May 2014, the Financial Accounting Standards Board ("FASB") codified guidance related to the recognition of revenue from contracts with customers. The new guidance outlined the core principle that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance is effective for annual reporting periods beginning after December 15, 2016, including interim periods within those reporting periods, with early adoption prohibited. The Partnership is currently assessing the impact, if any, that adoption of the new guidance will have on its consolidated financial position and results of operations.

The accompanying condensed consolidated financial statements are presented in accordance with the requirements of Form 10-Q and accounting principles generally accepted in the United States for interim financial reporting. They do not include all disclosures normally made in annual financial statements contained in Form 10-K. The accompanying condensed consolidated balance sheet at December 31, 2013 has been derived from the Partnership's audited financial statements for the year ended December 31, 2013. In management's opinion, all adjustments necessary for a fair presentation of the results of operations, financial position and cash flows for the periods shown have been made. All such adjustments are of a normal recurring nature. Results for the three and nine months ended September 30, 2014 are not necessarily indicative of results for the full year 2014.

Certain amounts in the prior year condensed consolidated financial statements have been reclassified to conform to the current-year presentation.

2. Changes in Business and Other Matters

In the second quarter 2014, the Partnership entered into a joint agreement to form Bayview Refining Company, LLC ("Bayview"). Bayview will construct and operate a facility that will process crude oil into intermediate petroleum products. The Partnership will fund construction of the facility through contributions proportionate to its 49 percent economic and voting interests, with the remaining portion funded by the joint owner through a promissory note entered into with the Partnership. Through September 30, 2014, the joint owners have made contributions totaling $21 million. The facility is expected to commence operations in the second half of 2015. Bayview is a variable interest entity of which the Partnership is not the primary beneficiary. As a result, the Partnership's investment in Bayview is reflected as an equity method investment within the Crude Oil Acquisition and Marketing segment.

In connection with the formation of Bayview, the joint owners agreed to guarantee the obligations of Bayview with respect to certain third-party operating agreements over a ten-year term. The fair value of the liability recognized in connection with the guarantee was not material in relation to the Partnership’s financial position at September 30, 2014.

6

In the first quarter 2014, the Partnership exercised its rights to acquire an additional ownership interest in Explorer Pipeline Company ("Explorer") from an affiliate of Chevron for $42 million, increasing the Partnership's ownership interest from 9.4 to 13.3 percent. Explorer owns approximately 1,400 miles of refined products pipelines running from the Gulf Coast of the United States to the Chicago, Illinois area. The fair value of the investment was estimated based on the fair value of the consideration transferred. The investment continues to be accounted for as an equity method investment within the Partnership's Refined Products Pipelines segment, with the equity income recorded based on the Partnership's ownership percentage for each period presented.

In the third quarter 2013, the Partnership entered into an agreement to form SunVit Pipeline LLC ("SunVit"), a joint venture with Vitol, Inc. ("Vitol"), in which each party will maintain a 50 percent economic and voting interest. SunVit will construct and own a crude oil pipeline, which will originate in Midland, Texas and run to Garden City, Texas. The new pipeline will connect to the Partnership's existing pipelines and, along with the Partnership's Permian Express 2 pipeline project, will provide additional takeaway capacity from the Permian Basin. SunVit is expected to commence operations in 2015. Under the terms of the joint agreement, each owner will fund construction of the pipeline and operating expenses in proportion with its ownership interest. Through September 30, 2014, the Partnership and Vitol have made contributions totaling $51 million. SunVit is reflected as an equity method investment within the Partnership's Crude Oil Pipelines segment.

No pro forma information has been presented, as the impact of these investments was not material to the Partnership's consolidated financial position or results of operations.

3. Acquisitions

In the second quarter 2014, the Partnership acquired a crude oil purchasing and marketing business from EDF Trading North America, LLC ("EDF"). The purchase consisted of a crude oil acquisition and marketing business and related assets for approximately 20 thousand barrels per day. The acquisition also included a promissory note that was convertible to an equity interest in a rail facility (see below). The acquisition is included in the Crude Oil Acquisition and Marketing segment.

Also in the second quarter 2014, the Partnership acquired a 55 percent economic and voting interest in Price River Terminal, LLC ("PRT"), a rail facility in Wellington, Utah. As the Partnership acquired a controlling financial interest in PRT, the entity is reflected as a consolidated subsidiary of the Partnership from the acquisition date and is included in the Crude Oil Acquisition and Marketing segment. The terms of the acquisition provide PRT’s noncontrolling interest holders the option to sell their interests to the Partnership at a price defined in the purchase agreement. As a result, the noncontrolling interests attributable to PRT are excluded from the Partnership's total equity and are instead reflected as redeemable interests in the condensed consolidated balance sheet as of September 30, 2014.

The $65 million purchase price for these acquisitions (net of cash received) consisted primarily of net working capital largely attributable to inventory ($24 million), properties, plants and equipment ($14 million), and intangible assets ($28 million). These preliminary fair value allocations also resulted in an increase to goodwill ($12 million) and redeemable noncontrolling interests ($15 million).

In the second quarter 2013, the Partnership acquired Sunoco, Inc.'s ("Sunoco") Marcus Hook facility and related assets (the "Marcus Hook Facility") for $60 million in cash including certain acquisition costs. The acquisition included terminalling and storage assets located in Pennsylvania and Delaware, and commercial agreements, including a reimbursement agreement under which Sunoco will reimburse the Partnership $40 million for certain operating expenses of the Marcus Hook Facility through March 31, 2017. The reimbursement proceeds are reflected as contributions to equity. The Partnership will be indemnified against environmental liabilities resulting from events which occurred at the Marcus Hook Facility prior to the closing of the transaction. Since the transaction was with an entity under common control, the assets acquired and liabilities assumed were recorded by the Partnership at Sunoco's net carrying value plus acquisition costs. The difference between Sunoco’s net carrying value and the consideration transferred was recorded as an increase to equity. The acquisition was included within the Terminal Facilities segment.

No pro forma information has been presented, as the impact of these acquisitions was not material in relation to the Partnership's consolidated financial position or results of operations.

4. Related Party Transactions

The Partnership is a consolidated subsidiary of Energy Transfer Partners, L.P. ("ETP"). ETP and one of its affiliates own Sunoco Partners LLC, the Partnership's general partner, and a 30.3 percent limited partner interest in the Partnership. The Partnership has various operating and administrative agreements with ETP and its affiliates, including Sunoco, which include the agreements described below.

7

Advances to Affiliated Companies

Through the second quarter 2014, the Partnership participated in Sunoco's centralized cash management program pursuant to a treasury services agreement. Under the program, the Partnership's cash receipts and cash disbursements were processed, together with those of Sunoco and its other subsidiaries, through Sunoco's cash accounts with a corresponding credit or charge to an affiliated account. In the fourth quarter 2013, the Partnership established separate cash accounts and began to transition to processing its own cash receipts and disbursements. The Partnership has completed the transition and ceased participation in Sunoco's cash management program.

Administrative Services

The Partnership has no employees. The operations of the Partnership are carried out by employees of the general partner and its affiliates. The Partnership reimburses the general partner and its affiliates for certain costs and direct expenses incurred on the Partnership's behalf. These costs may increase if the acquisition or construction of new businesses or assets requires an increase in the level of general and administrative services performed for the Partnership.

The Partnership pays ETP and its affiliates an annual administrative fee for expenses incurred by ETP and its affiliates to perform certain centralized corporate functions, such as legal, accounting, treasury, engineering, information technology, insurance, and other corporate services, including the administration of employee benefit plans. This fee does not include the cost of shared insurance programs (which are allocated to the Partnership based upon its share of the cash premiums incurred), the salaries or wages of employees of the general partner, or the cost of employee benefits.

The Partnership's share of allocated ETP employee benefit plan expenses, including noncontributory defined benefit retirement plans, defined contribution 401(k) plans, employee and retiree medical, dental and life insurance plans, incentive compensation plans and other such benefits are reflected in cost of products sold, operating expenses, and selling, general and administrative expenses in the condensed consolidated statements of comprehensive income.

Affiliated Revenues and Accounts Receivable, Affiliated Companies

The Partnership is party to various agreements with ETP and its affiliates (including Sunoco) to supply crude oil, refined products and NGLs, as well as to provide pipeline and terminalling services. The revenues associated with these activities are reflected as affiliated revenues in the condensed consolidated statements of comprehensive income.

The Partnership's note receivable in connection with its interest in Bayview (Note 2) is reflected in long-term note receivable, affiliated companies in the condensed consolidated balance sheet as of September 30, 2014.

Capital Contributions

During the nine months ended September 30, 2014, the Partnership issued 0.3 million limited partnership units to participants in the Sunoco Partners LLC Long-Term Incentive Plan ("LTIP") upon completion of award vesting requirements, compared to less than 0.1 million limited partnership units issued during the nine months ended September 30, 2013. In addition, during the nine months ended September 30, 2014, the Partnership issued 5.0 million limited partnership units under its at-the-market equity offering program ("ATM program"), which was established in the first quarter 2014 (Note 11). As a result of these issuances of limited partnership units, the Partnership recorded $2 million and less than $0.1 million of capital contributions from the general partner during the nine months ended September 30, 2014 and 2013, respectively. These contributions were previously required for the general partner to maintain its two percent general partner interest. In July 2014, the Partnership agreement was amended to remove the obligation of the general partner to make capital contributions upon the issuance of limited partner units to retain a two percent interest.

In connection with the acquisition of the Marcus Hook Facility in the second quarter 2013, the Partnership and Sunoco entered into an agreement under which Sunoco will reimburse the Partnership $40 million for certain operating expenses of the facility through March 31, 2017. The reimbursement proceeds are reflected as contributions to equity within the condensed consolidated balance sheets and statements of equity.

5. Net Income Attributable to Sunoco Logistics Partners L.P. per Limited Partner Unit

The general partner's interest in net income attributable to Sunoco Logistics Partners L.P. ("net income attributable to partners") through September 30, 2014 consists of its approximate two percent general partner interest and "incentive distributions," which are increasing percentages of up to 50 percent of quarterly distributions in excess of $0.0833 per common unit (Note 12). The general partner was allocated net income attributable to partners of $49 and $31 million (representing 32 and 40 percent of total net income attributable to partners) for the three months ended September 30, 2014 and 2013, respectively, and $131 and $88 million (representing 31 and 24 percent of total net income attributable to partners) for the nine months ended September 30, 2014 and 2013, respectively. Diluted net income attributable to partners per limited partner unit is

8

calculated by dividing the limited partners' interest in net income attributable to partners by the sum of the weighted average number of common units outstanding and the dilutive effect of unvested incentive unit awards (Note 13).

The following table reconciles the weighted average number of common units used to compute basic net income attributable to limited partners per unit to those used to compute diluted net income attributable to limited partners per unit for the three and nine months ended September 30, 2014 and 2013:

	Three Months Ended September 30,		Nine Months Ended September 30,
	2014	2013	2014	2013
	(in millions)		(in millions)
Weighted average number of units outstanding, basic (1)	212.5	207.6	209.6	207.6
Add effect of dilutive incentive awards(1)	1.3	1.1	1.2	0.9
Weighted average number of units, diluted(1)	213.8	208.7	210.8	208.5

⁽¹⁾ Amounts reflect the second quarter 2014 two-for-one unit split (Note 11).

7. Intangible Assets

The components of intangible assets are as follows:

	Weighted Average Amortization Period	September 30, 2014			December 31, 2013
	(in years)	(in millions)

Customer relationships		(90		)	(56		)
Technology		(10		)	(5		)
Total accumulated amortization		(100		)	(61		)
Total Net		$	783		$	794

In connection with the EDF acquisition in the second quarter 2014, the Partnership recognized intangible assets related to customer relationships. The customer relationship intangible assets represent the estimated economic value associated with certain relationships acquired in connection with the business combination whereby (i) the Partnership acquired information about or access to customers, (ii) the customers now have the ability to transact business with the Partnership and (iii) the Partnership is uniquely positioned to provide products or services to the customers. The customer relationship intangible assets are amortized on a straight-line basis over their respective economic lives.

Amortization expense was $14 and $12 million for the three months ended September 30, 2014 and 2013, respectively, and $39 and $37 million for the nine months ended September 30, 2014 and 2013, respectively. The Partnership forecasts approximately $51 million of annual amortization expense for each year through the year 2018 for these intangible assets.

Intangible assets associated with rights of way are included in properties, plants and equipment in the Partnership's condensed consolidated balance sheets.

8. Income Taxes

The Partnership is not a taxable entity for U.S. federal income tax purposes, or for the majority of states that impose income taxes. Rather, income taxes are generally assessed at the partner level. There are some states in which the Partnership operates where it is subject to state and local income taxes. Substantially all of the income tax amounts reflected in the Partnership's condensed consolidated financial statements are related to the operations of Inland, Mid-Valley and West Texas Gulf, all of which are entities subject to income taxes for federal and state purposes at the corporate level. The effective tax rates for these entities approximate the federal statutory rate of 35 percent.

In taxable jurisdictions, the Partnership records deferred income taxes on all significant temporary differences between the book basis and the tax basis of assets and liabilities. The net deferred tax liabilities reflected in the condensed consolidated balance sheets are derived principally from the differences in the book and tax bases of properties, plants and equipment of Inland, Mid-Valley and West Texas Gulf.

9. Debt

The components of the Partnership's debt balance are as follows:

	September 30, 2014			December 31, 2013

⁽¹⁾ Amounts outstanding under West Texas Gulf's $35 million Credit Facility at September 30, 2014 have been classified as long-term debt as West Texas Gulf has the ability and intent to refinance such borrowings on a long-term basis.

⁽²⁾ The 8.75 percent Senior Notes were classified as long-term debt at December 31, 2013 as the Partnership repaid these notes in February 2014 with borrowings under its $1.50 billion Credit Facility due in 2018.

Credit Facilities

The Operating Partnership maintains a $1.50 billion unsecured credit facility (the "$1.50 billion Credit Facility"), which matures in November 2018, to fund the Partnership's working capital requirements, to finance acquisitions and capital projects, to pay distributions and for general partnership purposes. The $1.50 billion Credit Facility contains an "accordion" feature, under which the total aggregate commitment may be extended to $2.25 billion under certain conditions. The facility bears interest at LIBOR or the Base Rate (as defined in the facility), each plus an applicable margin. The credit facility may be repaid

10

at any time. Outstanding borrowings under this credit facility were $525 and $200 million at September 30, 2014 and December 31, 2013, respectively.

The $1.50 billion Credit Facility contains various covenants including limitations on the creation of indebtedness and liens, and related to the operation and conduct of the business of the Partnership and its subsidiaries. The credit facility also limits the Partnership, on a rolling four quarter basis, to a maximum total consolidated debt to consolidated Adjusted EBITDA ratio, as defined in the underlying credit agreement, of 5.0 to 1, which can generally be increased to 5.5 to 1 during an acquisition period. The Partnership's ratio of total consolidated debt, excluding net unamortized fair value adjustments, to consolidated Adjusted EBITDA was 3.2 to 1 at September 30, 2014, as calculated in accordance with the credit agreement.

West Texas Gulf maintains a $35 million revolving credit facility (the "$35 million Credit Facility") which expires in April 2015. The facility is available to fund West Texas Gulf's general corporate activities, including working capital and capital expenditures. The $35 million Credit Facility contains various covenants limiting West Texas Gulf's ability to grant certain liens; make certain loans, acquisitions and investments; make any material changes to the nature of its business; or enter into a merger or sale of assets. The credit facility also limits West Texas Gulf, on a rolling four quarter basis, to a minimum fixed charge coverage ratio of 1.00 to 1, as defined in the underlying credit agreement. In addition, the credit facility limits West Texas Gulf to a maximum leverage ratio of 2.00 to 1. At September 30, 2014, West Texas Gulf's fixed charge coverage ratio and leverage ratio were 1.32 to 1 and 0.82 to 1, respectively. Outstanding borrowings under this credit facility were $35 million at September 30, 2014 and December 31, 2013.

Senior Notes

The Operating Partnership had $175 million of 8.75 percent senior notes which matured and were repaid in February 2014, using borrowings under the $1.50 billion Credit Facility.

In April 2014, the Operating Partnership issued $300 million of 4.25 percent Senior Notes and $700 million of 5.30 percent Senior Notes (the "2024 and 2044 Senior Notes"), due April 2024 and April 2044, respectively. The terms and conditions of the 2024 and 2044 Senior Notes are comparable to those of the Operating Partnership's other outstanding senior notes. The net proceeds from these offerings were used to repay outstanding borrowings under the $1.50 billion Credit Facility and for general partnership purposes.

10. Commitments and Contingent Liabilities

The Partnership is subject to numerous federal, state and local laws which regulate the discharge of materials into the environment or otherwise relate to the protection of the environment. These laws and regulations can result in liabilities and loss contingencies for remediation at the Partnership's facilities and at third-party or formerly owned sites. At September 30, 2014 and December 31, 2013, there were accrued liabilities for environmental remediation in the condensed consolidated balance sheets of $4 and $5 million, respectively. The accrued liabilities for environmental remediation do not include any amounts attributable to unasserted claims, since there are no unasserted claims that are probable of settlement or are reasonably estimable, nor have any recoveries from insurance been assumed. Charges against income for environmental remediation totaled $3 and $1 million for the three months ended September 30, 2014 and 2013, respectively, and $11 and $7 million for the nine months ended September 30, 2014 and 2013, respectively. The Partnership maintains insurance programs that cover certain of its existing or potential environmental liabilities. Claims for recovery of environmental liabilities and previous expenditures that are probable of realization were not material in relation to the Partnership's consolidated financial position at September 30, 2014.

Total future costs for environmental remediation activities will depend upon, among other things, the identification of any additional sites; the determination of the extent of the contamination at each site; the timing and nature of required remedial actions; the technology available and needed to meet the various existing legal requirements; the nature and extent of future environmental laws, inflation rates and the determination of the Partnership's liability at multi-party sites, if any, in light of uncertainties with respect to joint and several liability; and the number, participation levels and financial viability of other parties. Management believes it is reasonably possible that additional environmental remediation losses will be incurred. At September 30, 2014, the aggregate of the estimated maximum additional reasonably possible losses, which relate to numerous individual sites, totaled $6 million.

The Partnership is a party to certain pending and threatened claims. Although the ultimate outcome of these claims cannot be ascertained at this time, nor can a range of reasonably possible losses be determined, it is reasonably possible that some portion of them could be resolved unfavorably for the Partnership. Management does not believe that any liabilities which may arise from such claims or the environmental matters discussed above would be material in relation to the Partnership's financial position, results of operations or cash flows at September 30, 2014. Furthermore, management does not believe that the overall costs for such matters will have a material impact, over an extended period of time, on the Partnership's financial position, results of operations or cash flows.

11

Sunoco has indemnified the Partnership for 30 years for environmental and toxic tort liabilities related to the assets contributed to the Partnership, that arose from the operation of such assets prior to the closing of the February 2002 initial public offering ("IPO"). Sunoco has also indemnified the Partnership for 100 percent of all losses asserted within the first 21 years after the closing of the IPO. Sunoco's share of the liability for claims asserted thereafter will decrease by 10 percent per year. For example, for a claim asserted during the twenty-third year after the closing of the IPO, Sunoco would be required to indemnify the Partnership for 80 percent of its loss. There is no monetary cap on the amount of indemnity coverage provided by Sunoco. The Partnership has agreed to indemnify Sunoco for events and conditions associated with the operation of the Partnership's assets that occur on or after the closing of the IPO and for environmental and toxic tort liabilities to the extent that Sunoco is not required to indemnify the Partnership.

Management of the Partnership does not believe that any liabilities which may arise from claims indemnified by Sunoco would be material in relation to the Partnership's financial position, results of operations or cash flows at September 30, 2014. There are certain other pending legal proceedings related to matters arising after the IPO that are not indemnified by Sunoco. Management believes that any liabilities that may arise from these legal proceedings will not be material in relation to the Partnership's financial position, results of operations or cash flows at September 30, 2014.

11. Equity

The changes in the number of units outstanding from January 1, 2013 through September 30, 2014 are as follows:

	Common Units
	(in millions)
Balance at January 1, 2013	207.7
Units issued under incentive plans	—
Balance at December 31, 2013	207.7
Units issued in public offering	7.7
Units issued under ATM program	5.0
Units issued under incentive plans	0.3
Balance at September 30, 2014	220.7

On June 12, 2014, the Partnership completed a two-for-one split of its common units. The unit split resulted in the issuance of one additional common unit for every one common unit owned. All unit and per unit information included in this report are presented on a post-split basis.

In the first quarter 2014, the Partnership filed a registration statement and established a $250 million ATM program. The program allows the Partnership to issue common units directly to the public and raise capital in a timely and efficient manner to finance its growth capital program, while supporting the Partnership's investment grade credit ratings. For the three and nine months ended September 30, 2014, the Partnership issued 2.8 and 5.0 million common units under this program, for net proceeds of $129 and $231 million, respectively. All remaining units authorized under the $250 million ATM program were issued during October 2014.

In the third quarter 2014, the Partnership filed a registration statement which will allow the Partnership to issue up to an additional $1.0 billion of common units directly to the public under its ATM program.

In September 2014, the Partnership completed an overnight public offering of 7.7 million common units for net proceeds of $362 million. The net proceeds from this offering were used to repay outstanding borrowings under the $1.50 billion Credit Facility and for general partnership purposes.

12. Cash Distributions

Within 45 days after the end of each quarter, the Partnership distributes all cash on hand at the end of the quarter, less reserves established by the general partner at its discretion. This is defined as "available cash" in the partnership agreement. The general partner has broad discretion to establish cash reserves that it determines are necessary or appropriate to properly conduct the Partnership's business. The Partnership will make quarterly distributions to the extent there is sufficient cash from operations after the establishment of cash reserves and the payment of fees and expenses, including payments to the general partner.

If cash distributions exceed $0.0833 per unit in a quarter, the general partner will receive increasing percentages, up to 50 percent, of the cash distributed in excess of that amount. These distributions are referred to as "incentive distributions." The

12

percentage interests for the unitholders and the general partner for the minimum quarterly distribution are also applicable to the quarterly distribution amounts that are less than the minimum quarterly distribution.

The following table shows the target distribution levels and distribution "splits" between the general partner and the holders of the Partnership's common units through September 30, 2014:

				Marginal Percentage Interest in Distributions
	Total Quarterly Distribution Target Amount			General Partner			Unitholders
Minimum Quarterly Distribution		$	0.0750	2	%		98	%
First Target Distribution	up to	$	0.0833	2	%		98	%
	above	$ 0.0833
Second Target Distribution	up to	$ 0.0958		15	%	(1)	85	%
	above	$ 0.0958
Third Target Distribution	up to	$ 0.2638		37	%	(1)	63	%
Thereafter	above	$	0.2638	50	%	(1)	50	%

⁽¹⁾ Includes general partner interest.

The distributions paid by the Partnership for the periods presented were as follows:

Cash Distribution Payment Date	Cash Distribution per Limited Partner Unit		Total Cash Distribution to the Limited Partners		Total Cash Distribution  to the General Partner
			(in millions)		(in millions)
August 14, 2014	$	0.3650	$	77	$	43
May 15, 2014	$	0.3475	$	72	$	39
February 14, 2014	$	0.3312	$	69	$	35
November 14, 2013	$	0.3150	$	65	$	32
August 14, 2013	$	0.3000	$	62	$	29
May 15, 2013	$	0.2863	$	59	$	26
February 14, 2013	$	0.2725	$	57	$	23

On October 21, 2014, the Partnership's general partner announced a cash distribution of $0.3825 per common unit ($1.53 annualized), representing the distribution for the third quarter 2014. The $133 million distribution, including $49 million to the general partner for its interest and incentive distribution rights, will be paid on November 14, 2014 to unitholders of record on November 7, 2014.

13. Management Incentive Plan

The general partner has adopted the LTIP for employees and directors of the general partner who perform services for the Partnership. The LTIP is administered by the independent directors of the Compensation Committee of the general partner's board of directors with respect to employee awards, and by the general partner's board of directors with respect to awards granted to the independent directors. The LTIP currently permits the grant of restricted units and unit options covering an additional 0.8 million common units.

During the nine months ended September 30, 2014, the Partnership issued 0.3 million common units under the LTIP, compared to less than 0.1 million common units during the nine months ended September 30, 2013. The Partnership recognized share based compensation expense of $12 and $10 million for the nine months ended September 30, 2014 and 2013, respectively. Each of the outstanding restricted unit grants have tandem distribution equivalent rights which are recognized as a reduction to equity when earned.

14. Derivatives and Risk Management

The Partnership is exposed to various risks, including volatility in the prices of the products that the Partnership markets, counterparty credit risk and changes in interest rates.

Price Risk Management

The Partnership is exposed to risks associated with changes in the market price of crude oil, refined products and NGLs. These risks are primarily associated with price volatility related to pre-existing or anticipated purchases, sales and storage. Price changes are often caused by shifts in the supply and demand for these commodities, as well as their locations. In order to manage such exposure, the Partnership's policy is (i) to only purchase crude oil, refined products and NGLs for which sales contracts have been executed or for which ready markets exist, (ii) to structure sales contracts so that price fluctuations do not materially impact the margins earned, and (iii) not to acquire and hold physical inventory, futures contracts or other derivative instruments for the purpose of speculating on commodity price changes. Although the Partnership seeks to maintain a balanced inventory position within its commodity inventories, net unbalances may occur for short periods of time due to production, transportation and delivery variances. When physical inventory builds or draws do occur, the Partnership continuously manages the variances to a balanced position over a period of time.

The physical contracts related to the Partnership's crude oil, refined products and NGL businesses that qualify as derivatives are designated as normal purchases and sales and accounted for using accrual accounting under United States generally accepted accounting principles. The Partnership accounts for derivatives that do not qualify as normal purchases and sales at fair value. The Partnership currently does not utilize derivative instruments to manage its exposure to prices related to crude oil purchase and sale activities.

Pursuant to the Partnership's approved risk management policy, derivative contracts such as swaps, futures and other instruments may be used to hedge or reduce exposure to price risk associated with acquired inventory or forecasted physical transactions. The Partnership uses such derivative instruments to mitigate the risk associated with market movements in the price of refined products and NGLs. These derivative contracts act as a hedging mechanism against the volatility of prices by allowing the Partnership to transfer this price risk to counterparties who are able and willing to bear it. Since the first quarter 2013, the Partnership has not designated any of its derivative contracts as hedges for accounting purposes. Therefore, all realized and unrealized gains and losses from these derivative contracts are recognized in the condensed consolidated statement of comprehensive income as they are incurred. For refined products, derivative contracts that were designated and qualified as cash flow hedges during the first quarter 2013, the portion of the gain or loss on the derivative contract that was effective in offsetting the variable cash flows associated with the hedged forecasted transaction was reported as a component of other comprehensive income (loss) and reclassified into earnings in the same period or periods during which the hedged transaction affected earnings. The remaining gain or loss on the derivative contract in excess of the cumulative change in the present value of future cash flows of the hedged item, if any (i.e., the ineffective portion), was recognized immediately in earnings. The amount of hedge ineffectiveness on derivative contracts was not material during the first quarter 2013. All realized gains and losses associated with refined products derivative contracts are recorded in earnings in the same line item associated with the forecasted transaction (either in sales and other operating revenue or cost of products sold).

The Partnership had open derivative positions on approximately 7.0 and 1.6 million barrels of refined products and NGLs at September 30, 2014 and December 31, 2013, respectively. The derivatives outstanding as of September 30, 2014 vary in duration but do not extend beyond one year. The Partnership records its derivatives at fair value based on observable market prices (levels 1 and 2). As of September 30, 2014, the fair value of the Partnership's derivative assets and liabilities were $18 and $6 million, respectively, compared to $1 and $3 million, respectively, at December 31, 2013.

Derivative asset and liability balances are recorded in accounts receivable and accrued liabilities, respectively, in the condensed consolidated balance sheets.

The following table sets forth the impact of derivatives on the Partnership's results of operations for the three and nine months ended September 30, 2014 and 2013:

Cost of products sold	(3		)	4		(3		)	—
	$	19		$	5	$	10		$	2

Credit Risk Management

The Partnership maintains credit policies with regard to its counterparties that management believes minimize the overall credit risk through credit analysis, credit approvals, credit limits and monitoring procedures. The credit positions of the Partnership's customers are analyzed prior to the extension of credit and periodically after credit has been extended. The Partnership's counterparties consist primarily of financial institutions and major integrated oil companies. This concentration of counterparties may impact the Partnership's overall exposure to credit risk, either positively or negatively, as the counterparties may be similarly affected by changes in economic, regulatory or other conditions. At September 30, 2014 and December 31, 2013, the Partnership did not hold any over-the-counter derivatives.

Interest Rate Risk Management

The Partnership has interest rate risk exposure for changes in interest rates related to its outstanding borrowings. The Partnership manages its exposure to changes in interest rates through the use of a combination of fixed-rate and variable-rate debt. At September 30, 2014, the Partnership had $560 million of consolidated variable-rate borrowings under its revolving credit facilities.

15. Fair Value Measurements

The Partnership applies fair value accounting for all assets and liabilities that are required to be measured at fair value under current accounting rules. The assets and liabilities that are measured at fair value on a recurring basis are comprised primarily of derivatives.

The Partnership determines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Partnership utilizes valuation techniques that maximize the use of observable inputs (levels 1 and 2) and minimize the use of unobservable inputs (level 3) within the fair value hierarchy established by the FASB. The Partnership generally applies a "market approach" to determine fair value. This method uses pricing and other information generated by market transactions for identical or comparable assets and liabilities. Assets and liabilities are classified within the fair value hierarchy based on the lowest level (least observable) input that is significant to the measurement in its entirety.

The estimated fair value of the Partnership's financial instruments has been determined based on management's assessment of available market information and appropriate valuation methodologies. The Partnership's current assets (other than derivatives and inventories) and current liabilities (other than derivatives) are financial instruments and most of these items are recorded at cost in the condensed consolidated balance sheets. The estimated fair value of these financial instruments approximates their carrying value due to their short-term nature. The Partnership's derivatives are measured and recorded at fair value based on observable market prices (Note 14). The estimated fair values of the Partnership's senior notes are determined using observable market prices, as these notes are actively traded (level 1). The estimated aggregate fair value of the senior notes at September 30, 2014 was $3.09 billion, compared to the carrying amount of $3.08 billion. The estimated aggregate fair value of the senior notes at December 31, 2013 was $2.17 billion, compared to the carrying amount of $2.27 billion.

For further information regarding the Partnership's fair value measurements, see Notes 3 and 14.

Non-GAAP Financial Measures

To supplement our financial information presented in accordance with United States generally accepted accounting principles ("GAAP"), management uses additional measures that are known as "non-GAAP financial measures" in its evaluation of past performance and prospects for the future. The primary measures used by management are earnings before interest, taxes, depreciation and amortization expenses and other non-cash items ("Adjusted EBITDA"), and distributable cash flow ("DCF"). Adjusted EBITDA and DCF do not represent and should not be considered alternatives to net income or cash flows from operating activities as determined under GAAP and may not be comparable to similarly titled measures of other businesses.

Our management believes that Adjusted EBITDA and DCF information enhances an investor's understanding of a business's ability to generate cash for payment of distributions and other purposes. Adjusted EBITDA calculations are also defined and used as a measure in determining our compliance with certain revolving credit facility covenants. However, despite compliance with our credit facility covenants, there may be contractual, legal, economic or other factors which may prevent us from satisfying principal and interest obligations with respect to indebtedness and may require us to allocate funds for other purposes.

26

The following table reconciles the differences between net income, as determined under GAAP, and Adjusted EBITDA and DCF.

⁽¹⁾  During the third quarter 2014, we changed our definition of distributable cash flow to conform to the presentation utilized by Energy Transfer Partners, L.P., the controlling member of our general partner. This change did not have a material impact on our distributable cash flows. Prior period amounts have been recast to conform to current presentation.

Analysis of Consolidated Operating Results

Net income attributable to Sunoco Logistics Partners L.P. was $155 and $78 million for the three months ended September 30, 2014 and 2013, respectively. The increase was primarily attributable to higher operating results from our Crude Oil Acquisition and Marketing, Terminal Facilities, and Refined Products Pipelines segments and lower net interest costs driven by increased capitalized interest attributable to our expansion capital program. These improvements were partially offset by higher depreciation and amortization expense.

Net income attributable to Sunoco Logistics Partners L.P. was $418 and $361 million for the nine months ended September 30, 2014 and 2013, respectively. The increase was primarily attributable to higher operating results from our Crude Oil Pipelines, Terminal Facilities and Refined Products Pipelines segments and lower net interest costs driven by increased capitalized interest attributable to our expansion capital program. These improvements were partially offset by lower operating results from the Crude Oil Acquisition and Marketing segment, and higher depreciation and amortization expense.

Analysis of Operating Segments

We manage our operations through four operating segments: Crude Oil Pipelines, Crude Oil Acquisition and Marketing, Terminal Facilities and Refined Products Pipelines.

Crude Oil Pipelines

Our Crude Oil Pipelines segment consists of crude oil trunk and gathering pipelines in the southwest and midwest United States, including those owned by our joint venture interests. Revenues are generated from tariffs and the associated

27

fees paid by shippers utilizing our transportation services to deliver crude oil and other feedstocks to refineries within those regions. Rates for shipments on these pipelines are regulated by the Federal Energy Regulatory Commission ("FERC"), Oklahoma Corporation Commission and the Railroad Commission of Texas.

The following table summarizes the operating results and key operating measures for our Crude Oil Pipelines segment for the periods presented:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2014		2013		2014		2013
	(in millions, except for barrel amounts)				(in millions, except for barrel amounts)
Sales and other operating revenue:
Unaffiliated customers	$	88	$	86	$	244	$	210
Intersegment revenue	56		53		169		146
Total sales and other operating revenue	$	144	$	139	$	413	$	356
Depreciation and amortization expense	$	25	$	23	$	73	$	67
Adjusted EBITDA	$	95	$	98	$	292	$	247
Pipeline throughput (thousands of barrels per day ("bpd"))	2,204		1,976		2,126		1,817
Pipeline revenue per barrel (cents)	70.8		76.3		71.2		71.7

Adjusted EBITDA for the Crude Oil Pipelines segment decreased $3 million to $95 million for the three months ended September 30, 2014, as compared to $98 million for the three months ended September 30, 2013. The decrease in Adjusted EBITDA was attributable to lower average pipeline revenue per barrel ($11 million) and higher operating expenses ($6 million) which included lower pipeline operating gains. These negative impacts were largely offset by higher throughput volumes ($16 million) largely attributable to expansion projects placed in service in 2013 to support the demand for transportation of West Texas crude oil.

Adjusted EBITDA for the Crude Oil Pipelines segment increased $45 million to $292 million for the nine months ended September 30, 2014, as compared to $247 million for the nine months ended September 30, 2013. The increase in Adjusted EBITDA was due primarily to higher throughput volumes ($60 million) largely attributable to expansion projects placed in service in 2013 to support the demand for transportation of West Texas crude oil. This positive impact was partially offset by lower average pipeline revenue per barrel ($3 million) and higher operating expenses ($13 million) which included lower pipeline operating gains and increased utility expenses associated with higher throughput volumes.

Crude Oil Acquisition and Marketing

Our Crude Oil Acquisition and Marketing segment markets gathered and bulk purchased crude oil. The crude oil acquisition and marketing operations generate substantial revenue and cost of products sold as a result of the significant volume of crude oil sold and purchased. Although crude oil price levels significantly impact the revenue and cost of products sold for the Crude Oil Acquisition and Marketing segment, the absolute price levels of crude oil normally do not bear a relationship to gross profit. As a result, period-to-period variations in revenue and cost of products sold are not generally meaningful in analyzing the variation in gross profit for the segment. The operating results of the Crude Oil Acquisition and Marketing segment are affected by overall levels of supply and demand for crude oil and relative fluctuations in market related indices. Generally, we expect a base level of earnings from our Crude Oil Acquisition and Marketing segment that may be optimized and enhanced when there is a high level of market volatility, favorable basis differentials and/or a steep contango or backwardated market structure. Our management believes gross profit, which is equal to sales and other operating revenue less cost of products sold and operating expenses, is a key measure of financial performance for the Crude Oil Acquisition and Marketing segment. Although we implement risk management activities to provide general stability in our margins, these margins are not fixed and will vary from period-to-period.

28

The following table summarizes the operating results and key operating measures for our Crude Oil Acquisition and Marketing segment for the periods presented:

Adjusted EBITDA for the Crude Oil Acquisition and Marketing segment increased $48 million to $66 million for the three months ended September 30, 2014, as compared to $18 million for the three months ended September 30, 2013. The increase in Adjusted EBITDA was primarily attributable to higher crude oil margins ($43 million) driven by expanded crude oil differentials compared to the prior year period. Increased crude oil volumes ($5 million) resulting from higher market demand and the expansion of our crude oil trucking fleet also contributed to the increase.

Adjusted EBITDA for the Crude Oil Acquisition and Marketing segment decreased $69 million to $131 million for the nine months ended September 30, 2014, as compared to $200 million for the nine months ended September 30, 2013. The decrease in Adjusted EBITDA was primarily attributable to lower crude oil margins ($98 million) driven by contracted crude oil differentials compared to the prior year period. This impact was partially offset by increased crude oil volumes ($31 million) resulting from higher market demand and the expansion of our crude oil trucking fleet.

Terminal Facilities

Our Terminal Facilities segment consists of crude oil, refined products and natural gas liquids ("NGL") terminals, as well as a refined products and NGL acquisition and marketing business. The Terminal Facilities segment earns revenue by providing storage, terminalling, blending and other ancillary services to our customers, as well as through the sale of refined products and NGLs.

Adjusted EBITDA for the Terminal Facilities segment increased $14 million to $61 million for the three months ended September 30, 2014, as compared to $47 million for the three months ended September 30, 2013. The increase in Adjusted EBITDA was due primarily to improved contributions from our bulk marine terminals ($8 million) and higher volumes and increased margins from our refined products and NGLs acquisition and marketing activities ($6 million).

Adjusted EBITDA for the Terminal Facilities segment increased $73 million to $244 million for the nine months ended September 30, 2014, as compared to $171 million for the nine months ended September 30, 2013. The increase in Adjusted EBITDA was due primarily to higher volumes and increased margins from our refined products and NGLs acquisition and marketing activities ($63 million) and improved contributions from our bulk marine terminals ($16 million) primarily attributable to higher throughput volumes. These improvements were partially offset by lower volumes at our refined products terminals ($5 million).

Refined Products Pipelines

Our Refined Products Pipelines segment consists of refined products and NGLs pipelines, including a two-thirds undivided interest in the Harbor pipeline and joint-venture interests in four refined products pipelines in selected areas of the United States. The Refined Products Pipeline System primarily earns revenues by transporting products from refineries in the northeast, midwest and southwest United States to markets in six states and Canada. Rates for shipments on these pipelines are regulated by the FERC and the Pennsylvania Public Utility Commission.

⁽¹⁾ Excludes amounts attributable to equity interests which are not consolidated.

Adjusted EBITDA for the Refined Products Pipelines segment increased $6 million to $24 million for the three months ended September 30, 2014, as compared to $18 million for the three months ended September 30, 2013. The increase was due primarily to operating results from the Mariner West project ($10 million), which commenced operations in the fourth quarter 2013. This improvement was partially offset by lower pipeline operating gains ($2 million).

Adjusted EBITDA for the Refined Products Pipelines segment increased $24 million to $67 million for the nine months ended September 30, 2014, as compared to $43 million for the nine months ended September 30, 2013. The increase was due primarily to operating results from the Mariner West project ($32 million) and higher contributions from joint venture interests ($5 million). These improvements were partially offset by lower overall pipeline volumes ($3 million), higher operating expenses ($6 million) which included lower pipeline operating gains and increased employee costs.

Liquidity and Capital Resources

Liquidity

Cash generated from operations and borrowings under our $1.54 billion in credit facilities are our primary sources of liquidity. At September 30, 2014, we had a net working capital surplus of $345 million and available borrowing capacity of $975 million under our revolving credit facilities. The primary driver of our working capital surplus was an increase in accounts receivable, partially offset by an increase in accounts payable and lower advances to affiliated companies. We supplement our cash flows from operations with proceeds from our at-the-market equity offering program ("ATM program") and periodically with debt and equity financing activities.

Credit Facilities

We maintain a $1.50 billion unsecured credit facility (the "$1.50 billion Credit Facility"), which matures in November 2018, to fund our working capital requirements, to finance acquisitions and capital projects, to pay distributions and for general partnership purposes. The $1.50 billion Credit Facility contains an "accordion" feature, under which the total aggregate commitment may be extended to $2.25 billion under certain conditions. Outstanding borrowings under this credit facility were $525 and $200 million at September 30, 2014 and December 31, 2013, respectively.

The $1.50 billion Credit Facility contains various covenants including limitations on the creation of indebtedness and liens, and related to the operation and conduct of our business. The credit facility also limits us, on a rolling four quarter basis, to a maximum total consolidated debt to consolidated Adjusted EBITDA ratio, as defined in the underlying credit agreement, of 5.0 to 1, which can generally be increased to 5.5 to 1 during an acquisition period. Our ratio of total consolidated debt, excluding net unamortized fair value adjustments, to consolidated Adjusted EBITDA was 3.2 to 1 at September 30, 2014, as calculated in accordance with the credit agreement.

West Texas Gulf Pipe Line Company ("West Texas Gulf"), our consolidated subsidiary, maintains a $35 million revolving credit facility (the "$35 million Credit Facility") which expires in April 2015. The facility is available to fund West Texas Gulf's general corporate purposes including working capital and capital expenditures. The $35 million Credit Facility contains various covenants limiting West Texas Gulf's ability to grant certain liens; make certain loans, acquisitions and

31

investments; make any material changes to the nature of its business; or enter into a merger or sale of assets. The credit facility also limits West Texas Gulf, on a rolling four quarter basis, to a minimum fixed charge coverage ratio of 1.00 to 1, as defined in the underlying credit agreement. In addition, the credit facility limits West Texas Gulf to a maximum leverage ratio of 2.00 to 1. At September 30, 2014, West Texas Gulf's fixed charge coverage ratio and leverage ratio were 1.32 to 1 and 0.82 to 1, respectively. Outstanding borrowings under this credit facility were $35 million at September 30, 2014 and December 31, 2013.

Senior Notes

We had $175 million of 8.75 percent senior notes which matured and were repaid in February 2014.

In April 2014, we issued $300 million of 4.25 percent Senior Notes and $700 million of 5.30 percent Senior Notes (the "2024 and 2044 Senior Notes"), due April 2024 and April 2044, respectively. The terms and conditions of the 2024 and 2044 Senior Notes are comparable to those of our other outstanding senior notes. The net proceeds from these offerings were used to repay outstanding borrowings under the $1.50 billion Credit Facility and for general partnership purposes.

Equity Offerings

In the first quarter 2014, we filed a registration statement and established a $250 million ATM program. The program allows us to issue common units directly to the public and raise capital in a timely and efficient manner to finance our growth capital program, while supporting our investment grade credit ratings. For the three and nine months ended September 30, 2014, we issued 2.8 and 5.0 million common units under the program, for net proceeds of $129 and $231 million, respectively. All remaining units authorized under the $250 million ATM program were issued during October 2014.

In the third quarter 2014, we filed a registration statement which will allow us to issue up to an additional $1.0 billion of common units directly to the public under our ATM program.

In September 2014, we completed an overnight public offering of 7.7 million common units for net proceeds of $362 million. The net proceeds from this offering were used to repay outstanding borrowings under the $1.50 billion Credit Facility and for general partnership purposes.

Cash Flows and Capital Expenditures

Operating Activities

Cash flows from operating activities are primarily driven by earnings, excluding the impact of non-cash items, the timing of cash receipts and disbursements related to accounts receivable and payable, and the timing of inventory transactions and changes in other working capital amounts. Non-cash items include depreciation, amortization and certain compensation expenses. See the Analysis of Consolidated Operating Results, above, for more information on changes in our consolidated earnings.

Net cash provided by operating activities for the nine months ended September 30, 2014 of $326 million was primarily related to net income of $425 million and non-cash charges for depreciation and amortization of $220 million, partially offset by a $299 million increase in working capital largely attributable to an increase in our net receivables. Net cash provided by operating activities for the nine months ended September 30, 2013 of $461 million was primarily related to net income of $369 million and non-cash charges for depreciation and amortization of $196 million, partially offset by a $91 million increase in working capital largely attributable to increased inventories.

Investing Activities

Cash flows used in investing activities relate primarily to our capital expenditures, including expansion and maintenance capital, acquisitions and investments in joint venture interests. See "Capital Requirements," below, for additional details on our investing activities.

In addition to $1.8 billion of cash used for expansion and maintenance capital expenditures, net cash used in investing activities for the nine months ended September 30, 2014 included $65 million of acquisitions completed in the Crude Oil Acquisition and Marketing segment and $78 million of investment in joint venture interests. Net cash used in investing activities of $665 million for the nine months ended September 30, 2013 related to expansion capital projects, maintenance capital on our existing assets and the acquisition of the Marcus Hook facility for $60 million from Sunoco, Inc. ("Sunoco").

32

Financing Activities

Cash flows from financing activities relate primarily to the payment of distributions to partners; borrowings and repayments under our credit facilities; the cash impacts of debt and equity activities; and changes in advances to affiliated companies, which prior to our transition away from Sunoco's cash management program in 2014, represented our cash held by Sunoco in connection with our participation in that program.

Net cash provided by financing activities for the nine months ended September 30, 2014 of $1.6 billion resulted primarily from $989 million of net proceeds related to the April 2014 issuance of the 2024 and 2044 Senior Notes; the $593 million of net proceeds from the overnight public offering and our ATM program; the $325 million of net borrowings under our $1.50 billion Credit Facility; and the $239 million decrease in advances to affiliates, which represented our cash held by Sunoco in accordance with our participation in Sunoco's cash management program. These sources of cash were partially offset by $335 million in distributions paid to limited partners and the general partner and the $175 million repayment of the 8.75 percent Senior Notes which matured in February 2014. Net cash provided by financing activities in 2013 of $203 million resulted primarily from $691 million of net proceeds related to the January 2013 offering of the 2023 and 2043 Senior Notes. This source of cash was partially offset by $256 million in distributions paid to limited partners and the general partner, a $126 million increase in advances to affiliates and $104 million of net repayments under our credit facilities.

Capital Requirements

Our operations are capital intensive, requiring significant investment to maintain, upgrade and enhance existing assets and to comply with environmental and operational regulations. The capital requirements have consisted, and are expected to continue to consist, primarily of:

• Expansion capital expenditures to acquire and integrate complementary assets to improve operational efficiencies or reduce costs and to expand existing and construct new facilities, such as projects that increase storage or throughput volume,

• Maintenance capital expenditures that extend the usefulness of existing assets, such as those required to maintain equipment reliability, tankage and pipeline integrity and safety, and to address environmental regulations, and

• Acquisitions to acquire and integrate complementary assets to grow the business, to improve operational efficiencies or reduce costs.

The following table summarizes our capital expenditures for the periods presented:

	Nine Months Ended September 30,
	2014		2013
	(in millions)
Expansion	$	1,840	$	598
Maintenance	47		37
Acquisitions	80		60
Investment in joint venture interests	75		—
Total	$	2,042	$	695

Expansion capital expenditures for the nine months ended September 30, 2014 and 2013 included projects to: invest in the previously announced Mariner and Allegheny Access projects; invest in our crude oil infrastructure by increasing our pipeline capabilities through previously announced expansion capital projects in Texas and Oklahoma; expand the service capabilities of our refined products and NGLs acquisition and marketing business; and upgrade the service capabilities at our bulk marine terminals. We expect total expansion capital spending, excluding acquisitions and investment in joint venture interests, to be approximately $2.5 billion in 2014. Projected expansion capital includes spending to capture more value from existing assets such as the Marcus Hook facility, the Nederland terminal and our patented blending technology. Expansion capital spending, excluding acquisitions and investment in joint venture interests, is expected to be approximately $2 billion in 2015 in connection with our previously announced projects.

Maintenance capital expenditures for both periods presented primarily included recurring expenditures such as pipeline integrity costs; pipeline relocations; repair and upgrade of field instrumentation, including measurement devices; repair and replacement of tank floors and roofs; upgrades of cathodic protection systems; crude trucks and related equipment; and the upgrade of pump stations. We continue to estimate our maintenance capital spending to be approximately $70 million in 2014.

33

Acquisitions for the nine months ended September 30, 2014 included a crude oil acquisition and marketing business and related assets, and a controlling financial interest in a rail facility. Acquisitions for the nine months ended September 30, 2013 included our acquisition of the Marcus Hook facility from Sunoco.

Investment in joint venture interests in 2014 consisted of our acquisition of an additional ownership interest in Explorer Pipeline Company, which increased our ownership interest from 9.4 percent to 13.3 percent, and contributions to SunVit Pipeline LLC and Bayview Refining Company, LLC.

We expect to fund future capital expenditures, including any acquisitions, from cash provided by operations, with proceeds from debt and equity offerings and, to the extent necessary, from borrowings under our credit facilities.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to various risks, including volatility in the interest rates associated with our variable-rate debt and in the prices of the products that we market. In order to manage such exposure, debt levels, interest rates, inventory levels and expectations of future commodity prices are monitored when making decisions with respect to risk management.

Interest Rate Risk

We have interest rate risk exposure for changes in interest rates relating to our outstanding borrowings. We manage our exposure to changing interest rates through the use of a combination of fixed-rate and variable-rate debt. At September 30, 2014, we had $560 million of variable-rate borrowings under the revolving credit facilities. Outstanding borrowings bear interest cost at LIBOR plus an applicable margin. Our weighted average interest rate on our variable-rate borrowings was approximately 1 percent at September 30, 2014.

At September 30, 2014, we had $2.98 billion of fixed-rate borrowings associated with our outstanding senior notes, excluding $109 million of unamortized premiums. The estimated fair value of our senior notes was $3.09 billion at September 30, 2014. A hypothetical one-percent decrease in interest rates would increase the fair value of our fixed-rate borrowings by approximately $320 million at September 30, 2014.

Commodity Market Risk

We are exposed to volatility in the prices of the products we market. To manage such exposures, inventory levels and expectations regarding future commodity prices are monitored when making decisions with respect to risk management and inventory carried. Our policy is to purchase only commodity products for which we have a market, and to structure our sales contracts so that price fluctuations for those products do not materially affect the margins we receive. We also seek to maintain a position that is substantially balanced within our various commodity purchase and sale activities. We may experience net unbalanced positions for short periods of time as a result of production, transportation and delivery variances, as well as logistical issues associated with inclement weather conditions. When unscheduled physical inventory builds or draws occur, they are monitored and managed to a balanced position over a reasonable period of time.

We do not use futures or other derivative instruments to speculate on crude oil, refined products or natural gas liquids ("NGL") prices, as these activities could expose us to significant losses. We do use derivative contracts as economic hedges against price changes related to our forecasted refined products and NGLs purchase and sale activities. These derivatives are intended to have equal and opposite effects of the related physical purchase and sale activities. At September 30, 2014, the fair market value of our open derivative positions was a net asset of $12 million on 7.0 million barrels of refined products and NGLs. These derivative positions vary in length but do not extend beyond one year.

For additional information concerning our commodity market risk activities, see Note 14 to the condensed consolidated financial statements.

Item 4. Controls and Procedures

Disclosure controls and procedures are designed to ensure that information required to be disclosed in the Partnership's reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified by the rules and forms of the Securities and Exchange Commission. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in the Partnership's reports under the Exchange Act is accumulated and communicated to management, including the President and Chief Executive Officer and Chief Financial Officer of Sunoco Partners LLC (the Partnership's general partner), as appropriate, to allow timely decisions regarding required disclosure.

During the second quarter 2014, the Partnership implemented a new enterprise resource planning system, which includes applications to facilitate business processes such as accounting, financial reporting, and supply chain management. In connection with this transition, certain of the Partnership's internal controls were changed or modified accordingly. None of the changes were in response to any identified deficiency or weakness in the Partnership's internal control over financial reporting.

As of September 30, 2014, the Partnership carried out an evaluation, under the supervision and with the participation of the management of the general partner (including the President and Chief Executive Officer and the Chief Financial Officer), of the effectiveness of the design and operation of the Partnership's disclosure controls and procedures pursuant to Exchange Act Rule 13a-15. Based upon that evaluation, the general partner's President and Chief Executive Officer, and its Chief Financial Officer, concluded that the Partnership's disclosure controls and procedures were effective.

No change in the Partnership's internal control over financial reporting has occurred during the fiscal quarter ended September 30, 2014 that has materially affected, or that is reasonably likely to materially affect, the Partnership's internal control over financial reporting.

PART II.

OTHER INFORMATION

Item 1. Legal Proceedings

There are certain proceedings arising prior to the February 2002 initial public offering ("IPO") pending against our Sunoco, Inc. ("Sunoco") affiliated predecessors and us (as successor to certain liabilities of those predecessors). Although the ultimate outcome of these proceedings cannot be ascertained at this time, it is reasonably possible that some of them may be resolved unfavorably. Sunoco has agreed to indemnify the Partnership for 100 percent of all losses from environmental liabilities related to the transferred assets arising prior to, and asserted within 21 years of February 8, 2002. There is no monetary cap on this indemnification from Sunoco. Sunoco's share of liability for claims asserted thereafter will decrease by 10 percent each year through the thirtieth year following the February 8, 2002 date. Any remediation liabilities not covered by this indemnity will be our responsibility. In addition, Sunoco is obligated to indemnify us under certain other agreements executed after the IPO.

There are certain pending legal proceedings related to matters arising after the IPO that are not indemnified by Sunoco. Our management believes that any liabilities that may arise from these legal proceedings will not be material to our results of operations, financial position or cash flows at September 30, 2014.

The Partnership is a consolidated subsidiary of Energy Transfer Partners, L.P. ("ETP"). ETP and one of its affiliates own Sunoco Partners LLC, the Partnership's general partner, and a 30.3 percent limited partner interest in the Partnership. The Partnership has various operating and administrative agreements with ETP and its affiliates, including Sunoco, which include the agreements described below.

Advances to Affiliated Companies

Through the second quarter 2014, the Partnership participated in Sunoco's centralized cash management program pursuant to a treasury services agreement. Under the program, the Partnership's cash receipts and cash disbursements were processed, together with those of Sunoco and its other subsidiaries, through Sunoco's cash accounts with a corresponding credit or charge to an affiliated account. In the fourth quarter 2013, the Partnership established separate cash accounts and began to transition to processing its own cash receipts and disbursements. The Partnership has completed the transition and ceased participation in Sunoco's cash management program.

Administrative Services

The Partnership has no employees. The operations of the Partnership are carried out by employees of the general partner and its affiliates. The Partnership reimburses the general partner and its affiliates for certain costs and direct expenses incurred on the Partnership's behalf. These costs may increase if the acquisition or construction of new businesses or assets requires an increase in the level of general and administrative services performed for the Partnership.

The Partnership pays ETP and its affiliates an annual administrative fee for expenses incurred by ETP and its affiliates to perform certain centralized corporate functions, such as legal, accounting, treasury, engineering, information technology, insurance, and other corporate services, including the administration of employee benefit plans. This fee does not include the cost of shared insurance programs (which are allocated to the Partnership based upon its share of the cash premiums incurred), the salaries or wages of employees of the general partner, or the cost of employee benefits.

The Partnership's share of allocated ETP employee benefit plan expenses, including noncontributory defined benefit retirement plans, defined contribution 401(k) plans, employee and retiree medical, dental and life insurance plans, incentive compensation plans and other such benefits are reflected in cost of products sold, operating expenses, and selling, general and administrative expenses in the condensed consolidated statements of comprehensive income.

Affiliated Revenues and Accounts Receivable, Affiliated Companies

The Partnership is party to various agreements with ETP and its affiliates (including Sunoco) to supply crude oil, refined products and NGLs, as well as to provide pipeline and terminalling services. The revenues associated with these activities are reflected as affiliated revenues in the condensed consolidated statements of comprehensive income.

The Partnership's note receivable in connection with its interest in Bayview (Note 2) is reflected in long-term note receivable, affiliated companies in the condensed consolidated balance sheet as of September 30, 2014.

Capital Contributions

During the nine months ended September 30, 2014, the Partnership issued 0.3 million limited partnership units to participants in the Sunoco Partners LLC Long-Term Incentive Plan ("LTIP") upon completion of award vesting requirements, compared to less than 0.1 million limited partnership units issued during the nine months ended September 30, 2013. In addition, during the nine months ended September 30, 2014, the Partnership issued 5.0 million limited partnership units under its at-the-market equity offering program ("ATM program"), which was established in the first quarter 2014 (Note 11). As a result of these issuances of limited partnership units, the Partnership recorded $2 million and less than $0.1 million of capital contributions from the general partner during the nine months ended September 30, 2014 and 2013, respectively. These contributions were previously required for the general partner to maintain its two percent general partner interest. In July 2014, the Partnership agreement was amended to remove the obligation of the general partner to make capital contributions upon the issuance of limited partner units to retain a two percent interest.

In connection with the acquisition of the Marcus Hook Facility in the second quarter 2013, the Partnership and Sunoco entered into an agreement under which Sunoco will reimburse the Partnership $40 million for certain operating expenses of the facility through March 31, 2017. The reimbursement proceeds are reflected as contributions to equity within the condensed consolidated balance sheets and statements of equity.

Business Combinations [Abstract]

Acquistions

Acquisitions

In the second quarter 2014, the Partnership acquired a crude oil purchasing and marketing business from EDF Trading North America, LLC ("EDF"). The purchase consisted of a crude oil acquisition and marketing business and related assets for approximately 20 thousand barrels per day. The acquisition also included a promissory note that was convertible to an equity interest in a rail facility (see below). The acquisition is included in the Crude Oil Acquisition and Marketing segment.

Also in the second quarter 2014, the Partnership acquired a 55 percent economic and voting interest in Price River Terminal, LLC ("PRT"), a rail facility in Wellington, Utah. As the Partnership acquired a controlling financial interest in PRT, the entity is reflected as a consolidated subsidiary of the Partnership from the acquisition date and is included in the Crude Oil Acquisition and Marketing segment. The terms of the acquisition provide PRT’s noncontrolling interest holders the option to sell their interests to the Partnership at a price defined in the purchase agreement. As a result, the noncontrolling interests attributable to PRT are excluded from the Partnership's total equity and are instead reflected as redeemable interests in the condensed consolidated balance sheet as of September 30, 2014.

The $65 million purchase price for these acquisitions (net of cash received) consisted primarily of net working capital largely attributable to inventory ($24 million), properties, plants and equipment ($14 million), and intangible assets ($28 million). These preliminary fair value allocations also resulted in an increase to goodwill ($12 million) and redeemable noncontrolling interests ($15 million).

In the second quarter 2013, the Partnership acquired Sunoco, Inc.'s ("Sunoco") Marcus Hook facility and related assets (the "Marcus Hook Facility") for $60 million in cash including certain acquisition costs. The acquisition included terminalling and storage assets located in Pennsylvania and Delaware, and commercial agreements, including a reimbursement agreement under which Sunoco will reimburse the Partnership $40 million for certain operating expenses of the Marcus Hook Facility through March 31, 2017. The reimbursement proceeds are reflected as contributions to equity. The Partnership will be indemnified against environmental liabilities resulting from events which occurred at the Marcus Hook Facility prior to the closing of the transaction. Since the transaction was with an entity under common control, the assets acquired and liabilities assumed were recorded by the Partnership at Sunoco's net carrying value plus acquisition costs. The difference between Sunoco’s net carrying value and the consideration transferred was recorded as an increase to equity. The acquisition was included within the Terminal Facilities segment.

No pro forma information has been presented, as the impact of these acquisitions was not material in relation to the Partnership's consolidated financial position or results of operations.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization and Basis of Presentation

Organization and Basis of Presentation

Sunoco Logistics Partners L.P. (the "Partnership") is a publicly traded Delaware limited partnership that owns and operates a logistics business, consisting of crude oil, refined products and natural gas liquids ("NGL") pipelines, terminalling and storage assets, and crude oil, refined products and NGL acquisition and marketing assets. The Partnership conducts its business activities in 35 states located throughout the United States.

The condensed consolidated financial statements reflect the results of the Partnership and its wholly owned subsidiaries, including Sunoco Logistics Partners Operations L.P. (the "Operating Partnership"), the proportionate shares of the Partnership's undivided interests in assets, and the accounts of entities in which the Partnership has a controlling financial interest. The Partnership's controlling financial interests are attributed to voting interests greater than 50 percent. The Partnership holds a controlling financial interest in Inland Corporation ("Inland"), Mid-Valley Pipeline Company ("Mid-Valley"), West Texas Gulf Pipe Line Company ("West Texas Gulf") and Price River Terminal, LLC ("PRT"), which was acquired in the second quarter 2014 (Note 3), and as such, these entities are reflected as consolidated subsidiaries of the Partnership. The Partnership is not the primary beneficiary of any variable-interest entities ("VIEs"). All significant intercompany accounts and transactions are eliminated in consolidation, and noncontrolling interests in net income and equity are shown separately in the condensed consolidated statements of comprehensive income and balance sheets, respectively. Equity ownership interests in corporate joint ventures in which the Partnership does not have a controlling financial interest, but over which the Partnership can exercise significant influence, or VIEs in which the Partnership has a variable interest but of which the Partnership is not the primary beneficiary, are accounted for under the equity method of accounting.

In May 2014, the Financial Accounting Standards Board ("FASB") codified guidance related to the recognition of revenue from contracts with customers. The new guidance outlined the core principle that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance is effective for annual reporting periods beginning after December 15, 2016, including interim periods within those reporting periods, with early adoption prohibited. The Partnership is currently assessing the impact, if any, that adoption of the new guidance will have on its consolidated financial position and results of operations.

The accompanying condensed consolidated financial statements are presented in accordance with the requirements of Form 10-Q and accounting principles generally accepted in the United States for interim financial reporting. They do not include all disclosures normally made in annual financial statements contained in Form 10-K. The accompanying condensed consolidated balance sheet at December 31, 2013 has been derived from the Partnership's audited financial statements for the year ended December 31, 2013. In management's opinion, all adjustments necessary for a fair presentation of the results of operations, financial position and cash flows for the periods shown have been made. All such adjustments are of a normal recurring nature. Results for the three and nine months ended September 30, 2014 are not necessarily indicative of results for the full year 2014.

Certain amounts in the prior year condensed consolidated financial statements have been reclassified to conform to the current-year presentation.

Equity Method Investments and Joint Ventures [Abstract]

Change in Business and Other Matters

Changes in Business and Other Matters

In the second quarter 2014, the Partnership entered into a joint agreement to form Bayview Refining Company, LLC ("Bayview"). Bayview will construct and operate a facility that will process crude oil into intermediate petroleum products. The Partnership will fund construction of the facility through contributions proportionate to its 49 percent economic and voting interests, with the remaining portion funded by the joint owner through a promissory note entered into with the Partnership. Through September 30, 2014, the joint owners have made contributions totaling $21 million. The facility is expected to commence operations in the second half of 2015. Bayview is a variable interest entity of which the Partnership is not the primary beneficiary. As a result, the Partnership's investment in Bayview is reflected as an equity method investment within the Crude Oil Acquisition and Marketing segment.

In connection with the formation of Bayview, the joint owners agreed to guarantee the obligations of Bayview with respect to certain third-party operating agreements over a ten-year term. The fair value of the liability recognized in connection with the guarantee was not material in relation to the Partnership’s financial position at September 30, 2014.

In the first quarter 2014, the Partnership exercised its rights to acquire an additional ownership interest in Explorer Pipeline Company ("Explorer") from an affiliate of Chevron for $42 million, increasing the Partnership's ownership interest from 9.4 to 13.3 percent. Explorer owns approximately 1,400 miles of refined products pipelines running from the Gulf Coast of the United States to the Chicago, Illinois area. The fair value of the investment was estimated based on the fair value of the consideration transferred. The investment continues to be accounted for as an equity method investment within the Partnership's Refined Products Pipelines segment, with the equity income recorded based on the Partnership's ownership percentage for each period presented.

In the third quarter 2013, the Partnership entered into an agreement to form SunVit Pipeline LLC ("SunVit"), a joint venture with Vitol, Inc. ("Vitol"), in which each party will maintain a 50 percent economic and voting interest. SunVit will construct and own a crude oil pipeline, which will originate in Midland, Texas and run to Garden City, Texas. The new pipeline will connect to the Partnership's existing pipelines and, along with the Partnership's Permian Express 2 pipeline project, will provide additional takeaway capacity from the Permian Basin. SunVit is expected to commence operations in 2015. Under the terms of the joint agreement, each owner will fund construction of the pipeline and operating expenses in proportion with its ownership interest. Through September 30, 2014, the Partnership and Vitol have made contributions totaling $51 million. SunVit is reflected as an equity method investment within the Partnership's Crude Oil Pipelines segment.

No pro forma information has been presented, as the impact of these investments was not material to the Partnership's consolidated financial position or results of operations.

Cash Distributions

Cash Distributions

Within 45 days after the end of each quarter, the Partnership distributes all cash on hand at the end of the quarter, less reserves established by the general partner at its discretion. This is defined as "available cash" in the partnership agreement. The general partner has broad discretion to establish cash reserves that it determines are necessary or appropriate to properly conduct the Partnership's business. The Partnership will make quarterly distributions to the extent there is sufficient cash from operations after the establishment of cash reserves and the payment of fees and expenses, including payments to the general partner.

If cash distributions exceed $0.0833 per unit in a quarter, the general partner will receive increasing percentages, up to 50 percent, of the cash distributed in excess of that amount. These distributions are referred to as "incentive distributions." The percentage interests for the unitholders and the general partner for the minimum quarterly distribution are also applicable to the quarterly distribution amounts that are less than the minimum quarterly distribution.

The following table shows the target distribution levels and distribution "splits" between the general partner and the holders of the Partnership's common units through September 30, 2014:

				Marginal Percentage Interest in Distributions
	Total Quarterly Distribution Target Amount			General Partner			Unitholders
Minimum Quarterly Distribution		$	0.0750	2	%		98	%
First Target Distribution	up to	$	0.0833	2	%		98	%
	above	$ 0.0833
Second Target Distribution	up to	$ 0.0958		15	%	(1)	85	%

Third Target Distribution	up to	$ 0.2638		37	%	(1)	63	%
Thereafter	above	$	0.2638	50	%	(1)	50	%

⁽¹⁾ Includes general partner interest.

The distributions paid by the Partnership for the periods presented were as follows:

On October 21, 2014, the Partnership's general partner announced a cash distribution of $0.3825 per common unit ($1.53 annualized), representing the distribution for the third quarter 2014. The $133 million distribution, including $49 million to the general partner for its interest and incentive distribution rights, will be paid on November 14, 2014 to unitholders of record on November 7, 2014.

Management Incentive Plan

Management Incentive Plan

The general partner has adopted the LTIP for employees and directors of the general partner who perform services for the Partnership. The LTIP is administered by the independent directors of the Compensation Committee of the general partner's board of directors with respect to employee awards, and by the general partner's board of directors with respect to awards granted to the independent directors. The LTIP currently permits the grant of restricted units and unit options covering an additional 0.8 million common units.

During the nine months ended September 30, 2014, the Partnership issued 0.3 million common units under the LTIP, compared to less than 0.1 million common units during the nine months ended September 30, 2013. The Partnership recognized share based compensation expense of $12 and $10 million for the nine months ended September 30, 2014 and 2013, respectively. Each of the outstanding restricted unit grants have tandem distribution equivalent rights which are recognized as a reduction to equity when earned.

In connection with the EDF acquisition in the second quarter 2014, the Partnership recognized intangible assets related to customer relationships. The customer relationship intangible assets represent the estimated economic value associated with certain relationships acquired in connection with the business combination whereby (i) the Partnership acquired information about or access to customers, (ii) the customers now have the ability to transact business with the Partnership and (iii) the Partnership is uniquely positioned to provide products or services to the customers. The customer relationship intangible assets are amortized on a straight-line basis over their respective economic lives.

Amortization expense was $14 and $12 million for the three months ended September 30, 2014 and 2013, respectively, and $39 and $37 million for the nine months ended September 30, 2014 and 2013, respectively. The Partnership forecasts approximately $51 million of annual amortization expense for each year through the year 2018 for these intangible assets.

Intangible assets associated with rights of way are included in properties, plants and equipment in the Partnership's condensed consolidated balance sheets.

Derivatives and Risk Management

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives and Risk Management

Derivatives and Risk Management

The Partnership is exposed to various risks, including volatility in the prices of the products that the Partnership markets, counterparty credit risk and changes in interest rates.

Price Risk Management

The Partnership is exposed to risks associated with changes in the market price of crude oil, refined products and NGLs. These risks are primarily associated with price volatility related to pre-existing or anticipated purchases, sales and storage. Price changes are often caused by shifts in the supply and demand for these commodities, as well as their locations. In order to manage such exposure, the Partnership's policy is (i) to only purchase crude oil, refined products and NGLs for which sales contracts have been executed or for which ready markets exist, (ii) to structure sales contracts so that price fluctuations do not materially impact the margins earned, and (iii) not to acquire and hold physical inventory, futures contracts or other derivative instruments for the purpose of speculating on commodity price changes. Although the Partnership seeks to maintain a balanced inventory position within its commodity inventories, net unbalances may occur for short periods of time due to production, transportation and delivery variances. When physical inventory builds or draws do occur, the Partnership continuously manages the variances to a balanced position over a period of time.

The physical contracts related to the Partnership's crude oil, refined products and NGL businesses that qualify as derivatives are designated as normal purchases and sales and accounted for using accrual accounting under United States generally accepted accounting principles. The Partnership accounts for derivatives that do not qualify as normal purchases and sales at fair value. The Partnership currently does not utilize derivative instruments to manage its exposure to prices related to crude oil purchase and sale activities.

Pursuant to the Partnership's approved risk management policy, derivative contracts such as swaps, futures and other instruments may be used to hedge or reduce exposure to price risk associated with acquired inventory or forecasted physical transactions. The Partnership uses such derivative instruments to mitigate the risk associated with market movements in the price of refined products and NGLs. These derivative contracts act as a hedging mechanism against the volatility of prices by allowing the Partnership to transfer this price risk to counterparties who are able and willing to bear it. Since the first quarter 2013, the Partnership has not designated any of its derivative contracts as hedges for accounting purposes. Therefore, all realized and unrealized gains and losses from these derivative contracts are recognized in the condensed consolidated statement of comprehensive income as they are incurred. For refined products, derivative contracts that were designated and qualified as cash flow hedges during the first quarter 2013, the portion of the gain or loss on the derivative contract that was effective in offsetting the variable cash flows associated with the hedged forecasted transaction was reported as a component of other comprehensive income (loss) and reclassified into earnings in the same period or periods during which the hedged transaction affected earnings. The remaining gain or loss on the derivative contract in excess of the cumulative change in the present value of future cash flows of the hedged item, if any (i.e., the ineffective portion), was recognized immediately in earnings. The amount of hedge ineffectiveness on derivative contracts was not material during the first quarter 2013. All realized gains and losses associated with refined products derivative contracts are recorded in earnings in the same line item associated with the forecasted transaction (either in sales and other operating revenue or cost of products sold).

The Partnership had open derivative positions on approximately 7.0 and 1.6 million barrels of refined products and NGLs at September 30, 2014 and December 31, 2013, respectively. The derivatives outstanding as of September 30, 2014 vary in duration but do not extend beyond one year. The Partnership records its derivatives at fair value based on observable market prices (levels 1 and 2). As of September 30, 2014, the fair value of the Partnership's derivative assets and liabilities were $18 and $6 million, respectively, compared to $1 and $3 million, respectively, at December 31, 2013.

Derivative asset and liability balances are recorded in accounts receivable and accrued liabilities, respectively, in the condensed consolidated balance sheets.

The following table sets forth the impact of derivatives on the Partnership's results of operations for the three and nine months ended September 30, 2014 and 2013:

Credit Risk Management

The Partnership maintains credit policies with regard to its counterparties that management believes minimize the overall credit risk through credit analysis, credit approvals, credit limits and monitoring procedures. The credit positions of the Partnership's customers are analyzed prior to the extension of credit and periodically after credit has been extended. The Partnership's counterparties consist primarily of financial institutions and major integrated oil companies. This concentration of counterparties may impact the Partnership's overall exposure to credit risk, either positively or negatively, as the counterparties may be similarly affected by changes in economic, regulatory or other conditions. At September 30, 2014 and December 31, 2013, the Partnership did not hold any over-the-counter derivatives.

Interest Rate Risk Management

The Partnership has interest rate risk exposure for changes in interest rates related to its outstanding borrowings. The Partnership manages its exposure to changes in interest rates through the use of a combination of fixed-rate and variable-rate debt. At September 30, 2014, the Partnership had $560 million of consolidated variable-rate borrowings under its revolving credit facilities.

Commitments and Contingent Liabilities

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingent Liabilities

Commitments and Contingent Liabilities

The Partnership is subject to numerous federal, state and local laws which regulate the discharge of materials into the environment or otherwise relate to the protection of the environment. These laws and regulations can result in liabilities and loss contingencies for remediation at the Partnership's facilities and at third-party or formerly owned sites. At September 30, 2014 and December 31, 2013, there were accrued liabilities for environmental remediation in the condensed consolidated balance sheets of $4 and $5 million, respectively. The accrued liabilities for environmental remediation do not include any amounts attributable to unasserted claims, since there are no unasserted claims that are probable of settlement or are reasonably estimable, nor have any recoveries from insurance been assumed. Charges against income for environmental remediation totaled $3 and $1 million for the three months ended September 30, 2014 and 2013, respectively, and $11 and $7 million for the nine months ended September 30, 2014 and 2013, respectively. The Partnership maintains insurance programs that cover certain of its existing or potential environmental liabilities. Claims for recovery of environmental liabilities and previous expenditures that are probable of realization were not material in relation to the Partnership's consolidated financial position at September 30, 2014.

Total future costs for environmental remediation activities will depend upon, among other things, the identification of any additional sites; the determination of the extent of the contamination at each site; the timing and nature of required remedial actions; the technology available and needed to meet the various existing legal requirements; the nature and extent of future environmental laws, inflation rates and the determination of the Partnership's liability at multi-party sites, if any, in light of uncertainties with respect to joint and several liability; and the number, participation levels and financial viability of other parties. Management believes it is reasonably possible that additional environmental remediation losses will be incurred. At September 30, 2014, the aggregate of the estimated maximum additional reasonably possible losses, which relate to numerous individual sites, totaled $6 million.

The Partnership is a party to certain pending and threatened claims. Although the ultimate outcome of these claims cannot be ascertained at this time, nor can a range of reasonably possible losses be determined, it is reasonably possible that some portion of them could be resolved unfavorably for the Partnership. Management does not believe that any liabilities which may arise from such claims or the environmental matters discussed above would be material in relation to the Partnership's financial position, results of operations or cash flows at September 30, 2014. Furthermore, management does not believe that the overall costs for such matters will have a material impact, over an extended period of time, on the Partnership's financial position, results of operations or cash flows.

Sunoco has indemnified the Partnership for 30 years for environmental and toxic tort liabilities related to the assets contributed to the Partnership, that arose from the operation of such assets prior to the closing of the February 2002 initial public offering ("IPO"). Sunoco has also indemnified the Partnership for 100 percent of all losses asserted within the first 21 years after the closing of the IPO. Sunoco's share of the liability for claims asserted thereafter will decrease by 10 percent per year. For example, for a claim asserted during the twenty-third year after the closing of the IPO, Sunoco would be required to indemnify the Partnership for 80 percent of its loss. There is no monetary cap on the amount of indemnity coverage provided by Sunoco. The Partnership has agreed to indemnify Sunoco for events and conditions associated with the operation of the Partnership's assets that occur on or after the closing of the IPO and for environmental and toxic tort liabilities to the extent that Sunoco is not required to indemnify the Partnership.

Management of the Partnership does not believe that any liabilities which may arise from claims indemnified by Sunoco would be material in relation to the Partnership's financial position, results of operations or cash flows at September 30, 2014. There are certain other pending legal proceedings related to matters arising after the IPO that are not indemnified by Sunoco. Management believes that any liabilities that may arise from these legal proceedings will not be material in relation to the Partnership's financial position, results of operations or cash flows at September 30, 2014.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

The Partnership is not a taxable entity for U.S. federal income tax purposes, or for the majority of states that impose income taxes. Rather, income taxes are generally assessed at the partner level. There are some states in which the Partnership operates where it is subject to state and local income taxes. Substantially all of the income tax amounts reflected in the Partnership's condensed consolidated financial statements are related to the operations of Inland, Mid-Valley and West Texas Gulf, all of which are entities subject to income taxes for federal and state purposes at the corporate level. The effective tax rates for these entities approximate the federal statutory rate of 35 percent.

In taxable jurisdictions, the Partnership records deferred income taxes on all significant temporary differences between the book basis and the tax basis of assets and liabilities. The net deferred tax liabilities reflected in the condensed consolidated balance sheets are derived principally from the differences in the book and tax bases of properties, plants and equipment of Inland, Mid-Valley and West Texas Gulf.

⁽¹⁾ Amounts outstanding under West Texas Gulf's $35 million Credit Facility at September 30, 2014 have been classified as long-term debt as West Texas Gulf has the ability and intent to refinance such borrowings on a long-term basis.

⁽²⁾ The 8.75 percent Senior Notes were classified as long-term debt at December 31, 2013 as the Partnership repaid these notes in February 2014 with borrowings under its $1.50 billion Credit Facility due in 2018.

Credit Facilities

The Operating Partnership maintains a $1.50 billion unsecured credit facility (the "$1.50 billion Credit Facility"), which matures in November 2018, to fund the Partnership's working capital requirements, to finance acquisitions and capital projects, to pay distributions and for general partnership purposes. The $1.50 billion Credit Facility contains an "accordion" feature, under which the total aggregate commitment may be extended to $2.25 billion under certain conditions. The facility bears interest at LIBOR or the Base Rate (as defined in the facility), each plus an applicable margin. The credit facility may be repaid at any time. Outstanding borrowings under this credit facility were $525 and $200 million at September 30, 2014 and December 31, 2013, respectively.

The $1.50 billion Credit Facility contains various covenants including limitations on the creation of indebtedness and liens, and related to the operation and conduct of the business of the Partnership and its subsidiaries. The credit facility also limits the Partnership, on a rolling four quarter basis, to a maximum total consolidated debt to consolidated Adjusted EBITDA ratio, as defined in the underlying credit agreement, of 5.0 to 1, which can generally be increased to 5.5 to 1 during an acquisition period. The Partnership's ratio of total consolidated debt, excluding net unamortized fair value adjustments, to consolidated Adjusted EBITDA was 3.2 to 1 at September 30, 2014, as calculated in accordance with the credit agreement.

West Texas Gulf maintains a $35 million revolving credit facility (the "$35 million Credit Facility") which expires in April 2015. The facility is available to fund West Texas Gulf's general corporate activities, including working capital and capital expenditures. The $35 million Credit Facility contains various covenants limiting West Texas Gulf's ability to grant certain liens; make certain loans, acquisitions and investments; make any material changes to the nature of its business; or enter into a merger or sale of assets. The credit facility also limits West Texas Gulf, on a rolling four quarter basis, to a minimum fixed charge coverage ratio of 1.00 to 1, as defined in the underlying credit agreement. In addition, the credit facility limits West Texas Gulf to a maximum leverage ratio of 2.00 to 1. At September 30, 2014, West Texas Gulf's fixed charge coverage ratio and leverage ratio were 1.32 to 1 and 0.82 to 1, respectively. Outstanding borrowings under this credit facility were $35 million at September 30, 2014 and December 31, 2013.

Senior Notes

The Operating Partnership had $175 million of 8.75 percent senior notes which matured and were repaid in February 2014, using borrowings under the $1.50 billion Credit Facility.

In April 2014, the Operating Partnership issued $300 million of 4.25 percent Senior Notes and $700 million of 5.30 percent Senior Notes (the "2024 and 2044 Senior Notes"), due April 2024 and April 2044, respectively. The terms and conditions of the 2024 and 2044 Senior Notes are comparable to those of the Operating Partnership's other outstanding senior notes. The net proceeds from these offerings were used to repay outstanding borrowings under the $1.50 billion Credit Facility and for general partnership purposes.

The changes in the number of units outstanding from January 1, 2013 through September 30, 2014 are as follows:

	Common Units
	(in millions)
Balance at January 1, 2013	207.7
Units issued under incentive plans	—
Balance at December 31, 2013	207.7
Units issued in public offering	7.7
Units issued under ATM program	5.0
Units issued under incentive plans	0.3
Balance at September 30, 2014	220.7

On June 12, 2014, the Partnership completed a two-for-one split of its common units. The unit split resulted in the issuance of one additional common unit for every one common unit owned. All unit and per unit information included in this report are presented on a post-split basis.

In the first quarter 2014, the Partnership filed a registration statement and established a $250 million ATM program. The program allows the Partnership to issue common units directly to the public and raise capital in a timely and efficient manner to finance its growth capital program, while supporting the Partnership's investment grade credit ratings. For the three and nine months ended September 30, 2014, the Partnership issued 2.8 and 5.0 million common units under this program, for net proceeds of $129 and $231 million, respectively. All remaining units authorized under the $250 million ATM program were issued during October 2014.

In the third quarter 2014, the Partnership filed a registration statement which will allow the Partnership to issue up to an additional $1.0 billion of common units directly to the public under its ATM program.

In September 2014, the Partnership completed an overnight public offering of 7.7 million common units for net proceeds of $362 million. The net proceeds from this offering were used to repay outstanding borrowings under the $1.50 billion Credit Facility and for general partnership purposes.

Earnings Per Share [Abstract]

Net Income Attributable to Sunoco Logistics Partners L.P. per Limited Partner Unit

Net Income Attributable to Sunoco Logistics Partners L.P. per Limited Partner Unit

The general partner's interest in net income attributable to Sunoco Logistics Partners L.P. ("net income attributable to partners") through September 30, 2014 consists of its approximate two percent general partner interest and "incentive distributions," which are increasing percentages of up to 50 percent of quarterly distributions in excess of $0.0833 per common unit (Note 12). The general partner was allocated net income attributable to partners of $49 and $31 million (representing 32 and 40 percent of total net income attributable to partners) for the three months ended September 30, 2014 and 2013, respectively, and $131 and $88 million (representing 31 and 24 percent of total net income attributable to partners) for the nine months ended September 30, 2014 and 2013, respectively. Diluted net income attributable to partners per limited partner unit is calculated by dividing the limited partners' interest in net income attributable to partners by the sum of the weighted average number of common units outstanding and the dilutive effect of unvested incentive unit awards (Note 13).

The following table reconciles the weighted average number of common units used to compute basic net income attributable to limited partners per unit to those used to compute diluted net income attributable to limited partners per unit for the three and nine months ended September 30, 2014 and 2013:

	Three Months Ended September 30,		Nine Months Ended September 30,

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

The Partnership applies fair value accounting for all assets and liabilities that are required to be measured at fair value under current accounting rules. The assets and liabilities that are measured at fair value on a recurring basis are comprised primarily of derivatives.

The Partnership determines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Partnership utilizes valuation techniques that maximize the use of observable inputs (levels 1 and 2) and minimize the use of unobservable inputs (level 3) within the fair value hierarchy established by the FASB. The Partnership generally applies a "market approach" to determine fair value. This method uses pricing and other information generated by market transactions for identical or comparable assets and liabilities. Assets and liabilities are classified within the fair value hierarchy based on the lowest level (least observable) input that is significant to the measurement in its entirety.

The estimated fair value of the Partnership's financial instruments has been determined based on management's assessment of available market information and appropriate valuation methodologies. The Partnership's current assets (other than derivatives and inventories) and current liabilities (other than derivatives) are financial instruments and most of these items are recorded at cost in the condensed consolidated balance sheets. The estimated fair value of these financial instruments approximates their carrying value due to their short-term nature. The Partnership's derivatives are measured and recorded at fair value based on observable market prices (Note 14). The estimated fair values of the Partnership's senior notes are determined using observable market prices, as these notes are actively traded (level 1). The estimated aggregate fair value of the senior notes at September 30, 2014 was $3.09 billion, compared to the carrying amount of $3.08 billion. The estimated aggregate fair value of the senior notes at December 31, 2013 was $2.17 billion, compared to the carrying amount of $2.27 billion.

For further information regarding the Partnership's fair value measurements, see Notes 3 and 14.
