Basis of Presentation

1. 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 refined products and crude oil pipelines, terminalling and storage assets, and refined products and crude oil acquisition and marketing assets. The Partnership is principally engaged in the transport, terminalling and storage of refined products and crude oil and the purchase and sale of crude oil, in 29 states located throughout the United States. Sunoco, Inc. and its wholly-owned subsidiaries including Sunoco, Inc. (R&M) are collectively referred to as “Sunoco.” Sunoco accounted for 4.8 percent of the Partnership’s total revenues for the six months ended June 30, 2012.

In April 2012, Sunoco entered into an agreement to be acquired by Energy Transfer Partners (“ETP”). In connection with this transaction, ETP will also become the owner of Sunoco’s interest in the Partnership including the general partner and the incentive distribution rights, as well as Sunoco’s 32.4 percent interest in the Partnership’s limited partner units. The transaction is expected to close in the fourth quarter 2012, subject to approval of Sunoco’s shareholders and customary regulatory approvals. In addition, under the merger agreement, Sunoco will continue its plan to exit its refining business, including the announced joint venture with the Philadelphia refinery. The Partnership does not expect that the proposed acquisition will have a material impact on its operations.

The consolidated financial statements reflect the results of Sunoco Logistics Partners L.P. and its wholly-owned subsidiaries, including Sunoco Logistics Partners Operations L.P., and include the accounts of entities in which the Partnership has a controlling financial interest. A controlling financial interest is evidenced by either a voting interest greater than 50 percent or a risk and rewards model that identifies the Partnership or one of its subsidiaries as the primary beneficiary of a variable interest entity. The Partnership holds a controlling financial interest in Inland Corporation (“Inland”), Mid-Valley Pipeline Company (“Mid-Valley”) and West Texas Gulf Pipe Line Company (“West Texas Gulf”), and as such, these joint ventures are reflected as consolidated subsidiaries of the Partnership from the respective dates of acquisition. All significant intercompany accounts and transactions are eliminated in consolidation and noncontrolling interests in equity and net income are shown separately in the condensed consolidated balance sheets and statements of comprehensive income. Equity ownership interests in corporate joint ventures in which the Partnership does not have a controlling financial interest are accounted for under the equity method of accounting.

In June 2011, the Financial Accounting Standards Board (“FASB”) codified guidance related to the presentation of comprehensive income. The guidance requires entities to present net income and other comprehensive income in a single continuous statement of comprehensive income or in two separate, but consecutive, statements. For the six months ended June 30, 2012, the Partnership presents the components of net income and total comprehensive income in its consolidated statements of comprehensive income. The new guidance does not change the components that are recognized in net income and the components that are recognized in other comprehensive income. The revised presentation has been retroactively applied to all periods presented.

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 financial statements contained in Form 10-K. 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. The Partnership expects the interim increase in quantities of crude oil inventory to decline by year end and therefore has adjusted its interim LIFO calculation to produce a reasonable matching of the most recently incurred costs with current revenues. Results for the three and six months ended June 30, 2012 are not necessarily indicative of results for the full year 2012.

Change In Business And Other Matters

2. Change in Business and Other Matters

In February 2012, the Partnership sold its refined product terminal and pipeline assets in Big Sandy, Texas for $11 million. The buyer also assumed a $1 million environmental liability associated with the assets. The net book value of the assets sold and liability transferred approximated the sale price. In connection with the sale, the Partnership also agreed to cancel existing throughput and deficiency agreements in exchange for cash payments of $11 million. During the first quarter 2012, the Partnership recognized a total gain of $11 million, which primarily related to the contract settlement. The gain was recorded as $5 and $6 million within the Refined Products Pipelines and Terminal Facilities segments, respectively.

In July 2012, Sunoco announced that it has agreed to form Philadelphia Energy Solutions, a joint venture with The Carlyle Group, at its Philadelphia refinery, enabling the facility to continue operating. During the second quarter 2012, the Partnership reversed $10 million of regulatory obligations for tank cleaning which was previously expected to be performed if the Philadelphia refinery was shut down.

Related Party Transactions

3. Related Party Transactions

Advances to/from Affiliate

The Partnership has a treasury services agreement with Sunoco pursuant to which it, among other things, participates in Sunoco’s centralized cash management program. Under this program, all of the Partnership’s cash receipts and cash disbursements are processed, together with those of Sunoco and its other subsidiaries, through Sunoco’s cash accounts with a corresponding credit or charge to an intercompany account. The intercompany balances are settled periodically, but no less frequently than monthly. Amounts due from Sunoco earn interest at a rate equal to the average rate of the Partnership’s third-party money market investments, while amounts due to Sunoco bear interest at a rate equal to the interest rate provided in the Operating Partnership’s $350 million Credit Facility (see Note 8).

Administrative Services

Under the Omnibus Agreement, the Partnership pays Sunoco or the general partner an annual administrative fee that includes expenses incurred by Sunoco 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 was $13 million for the year ended December 31, 2011. The fee increased to $18 million for 2012 to cover additional consolidation of services provided by Sunoco that were previously provided by third parties and includes an allocation of certain senior management costs from Sunoco that were previously included in the Partnership’s direct costs. 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 of pipeline and terminal personnel or other employees of the general partner or the cost of their employee benefits. The Partnership has no employees, and reimburses Sunoco and its affiliates for these costs and other direct expenses incurred on the Partnership’s behalf. These costs may be increased if the acquisition or construction of new assets or businesses requires an increase in the level of general and administrative services received by the Partnership.

In addition to the fees for the centralized corporate functions, selling, general and administrative expenses in the consolidated statements of comprehensive income include the allocation of shared insurance costs. The Partnership’s share of allocated Sunoco 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 and operating expenses and selling, general and administrative expenses in the consolidated statements of comprehensive income.

Affiliated Revenues and Accounts Receivable, Affiliated Companies

The Partnership is party to various agreements with Sunoco to supply crude oil and refined products and to provide pipeline and terminalling services. Affiliated revenues in the consolidated statements of comprehensive income consist of sales of refined products and crude oil as well as the related provision, and services including pipeline transportation, terminalling, and storage and blending for Sunoco. Affiliated revenues include sales of crude oil to Sunoco which were priced using market-based rates and sales of refined products which are priced using market based rates under agreements that are negotiated annually. Service revenues are recognized based on published tariffs or negotiated rates.

During 2011, Sunoco continued to execute its strategy to exit its refining operations which included selling its Toledo, Ohio refinery in March 2011 and announcing its intention to sell its remaining refineries located in Philadelphia and Marcus Hook, PA. In December 2011, Sunoco indefinitely idled the main processing units at its Marcus Hook refinery and is currently pursing options for alternative uses of the facility. In July 2012 Sunoco announced that it has agreed to form Philadelphia Energy Solutions, a joint venture with The Carlyle Group, at its Philadelphia refinery, enabling the facility to continue operating.

Management has continued to assess the impact that Sunoco’s decision to exit its refining business in the northeast will have on the Partnership’s assets that have historically served the refineries and determined that the Partnership’s refined products pipeline and terminal assets continue to have expected future cash flows that support their carrying values. However, the Partnership recognized a $42 million charge in the fourth quarter 2011 for certain crude oil terminal assets which would be negatively impacted if the Philadelphia refinery is permanently idled. This includes a $31 million non-cash impairment for asset write-downs at the Fort Mifflin Terminal Complex and $11 million for regulatory obligations which would be incurred if these assets are permanently idled. During the second quarter 2012, the Partnership recognized a $10 million gain on the reversal of certain regulatory obligations for tank cleaning which will be delayed as a result of the announced joint venture with the Philadelphia refinery.

Capital Contributions

In the first six months of 2012 and 2011, the Partnership issued 0.2 million limited partnership units to participants in the Sunoco Partners LLC Long-Term Incentive Plan (“LTIP”) upon completion of award vesting requirements. As a result of these issuances of limited partnership units, the general partner contributed less than $1 million during the first six months of 2012 and 2011 to maintain its 2 percent general partner interest. The Partnership recorded these amounts as capital contributions to Equity within its condensed consolidated balance sheets.

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

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

4. Net Income Attributable to Sunoco Logistics Partners L.P. Per Limited Partner Unit Data

The general partner’s interest in net income attributable to Sunoco Logistics Partners L.P. (“net income attributable to Partners”) consists of its 2 percent general partner interest and “incentive distributions,” which are increasing percentages, up to 50 percent of quarterly distributions in excess of $0.1667 per common unit (see Note 11). The general partner was allocated net income attributable to Partners of $19 and $14 million (representing 13 and 15 percent respectively of total net income attributable to Partners) for the three months ended June 30, 2012 and 2011, respectively and $34 and $26 million (representing 14 and 18 percent of total net income attributable to Partners) for the six months ended June 30, 2012 and 2011, respectively. Diluted net income attributable to Partners per common unit is calculated by dividing net income attributable to Partners by the sum of the weighted average number of common and Class A units outstanding and the dilutive effect of incentive unit awards (see Note 12).

In July 2011, the Partnership issued 3.9 million Class A units to Sunoco in connection with the acquisition of the Eagle Point tank farm and related assets. These deferred distribution units represented a new class of units that were converted to common units in July 2012. The Class A units participated in the allocation of net income on a pro-rata basis with the common units.

Income Taxes

6. 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 reflected in the Partnership’s consolidated financial statements is derived from 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 on the condensed consolidated balance sheets are derived principally from the difference in the book and tax bases of properties, plants and equipment associated with the Inland, Mid-Valley and West Texas Gulf acquisitions.

Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Credit Facilities

The Partnership maintains two credit facilities totaling $550 million to fund the Partnership’s working capital requirements, finance acquisitions and capital projects and for general partnership purposes. The credit facilities consist of a five-year $350 million unsecured credit facility (the “$350 million Credit Facility”) and a $200 million 364-day unsecured credit facility (the “$200 million Credit Facility”). Outstanding borrowings under these credit facilities were $106 million at June 30, 2012. At December 31, 2011 there were no outstanding borrowings under these credit facilities.

The $350 and $200 million Credit Facilities contain various covenants limiting the Partnership’s ability to incur indebtedness; grant certain liens; make certain loans, acquisitions and investments; make any material change to the nature of its business; or enter into a merger or sale of assets, including the sale or transfer of interests in the Operating Partnership’s subsidiaries. The credit facilities also limit the Partnership, on a rolling four-quarter basis, to a maximum total consolidated debt to consolidated EBITDA, as defined in the underlying credit agreements, ratio 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 debt to EBITDA was 2.3 to 1 at June 30, 2012, as calculated in accordance with the credit agreements.

In April 2012, Sunoco announced that it has entered into a definitive merger agreement to be acquired by ETP. Successful completion of the acquisition would represent an event of default under the Partnership’s credit facilities as the general partner interests would no longer be owned by Sunoco. The Partnership continues to monitor the progress of the proposed transaction and, as necessary, expects to amend this condition so that no event of default will occur if the acquisition is completed.

In May 2012, West Texas Gulf entered into a $35 million revolving credit facility (the “$35 million Credit Facility”), which matures in April 2015. The facility is available to fund West Texas Gulf’s general corporate purposes including working capital and capital expenditures. The credit facility limits West Texas Gulf on a rolling four-quarter basis, to a minimum fixed charge coverage ratio, as defined in the underlying credit agreement. The ratio for the fiscal quarter ending June 30, 2012 shall not be less than 0.85 to 1. The minimum ratio fluctuates between 0.80 to 1 and 1.00 to 1 throughout the term of the revolver as specified in the credit agreement. In addition, the credit facility limits West Texas Gulf to a maximum leverage ratio of 2.00 to 1. West Texas Gulf’s fixed charge coverage ratio and leverage ratio were 1.04 to 1 and 0.18 to 1, respectively, at June 30, 2012. Outstanding borrowings under this

Commitments And Contingent Liabilities

9. 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 that 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 June 30, 2012 and December 31, 2011, there were accrued liabilities for environmental remediation in the condensed consolidated balance sheets of $4 million. The accrued liabilities for environmental remediation do not include any amounts attributable to unasserted claims, since no unasserted claims are probable of settlement or reasonably estimable, nor have any recoveries from insurance been assumed. Charges against income for environmental remediation totaled $1 million for the three months ended June 30, 2012 and 2011, respectively and $5 and $3 million for the six months ended June 30, 2012 and 2011, 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 totaled $14 million at June 30, 2012 and are included in other assets in the condensed consolidated balance sheets.

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.

Sunoco has indemnified the Partnership for 30 years from 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 indemnified the Partnership for 100 percent of all losses asserted within the first 21 years of closing of the IPO. Sunoco’s share of liability for claims asserted thereafter will decrease by 10 percent per year. For example, for a claim asserted during the twenty-third year after 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 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 results of operations, financial position or cash flows of the Partnership at June 30, 2012. 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 results of operations, financial position or cash flows at June 30, 2012.

Cash Distributions

11. 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 $0.1667 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 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:


	Total Quarterly Distribution Target Amount		Marginal Percentage Interest in Distributions
	Total Quarterly Distribution Target Amount		General Partner			Unitholders
Minimum Quarterly distribution	$	0.1500		2	%		98	%
First Target Distribution		up to $0.1667		2	%		98	%
Second Target Distribution		above $ 0.1667

*	Includes 2 percent general partner interest.

The distributions paid by the Partnership for the period from January 1, 2011 through June 30, 2012 are summarized below.

On August 2, 2012, Sunoco Partners LLC, the general partner of Sunoco Logistics Partners L.P., declared a cash distribution of $0.4700 per common unit ($1.88 annualized), representing the distribution for the second quarter 2012. The $66 million distribution, including $17 million to the general partner, will be paid on August 14, 2012 to common unitholders of record on August 8, 2012. The August 2012 payment will include distributions on the Class A units which were converted to common units in July 2012.

Derivatives and Risk Management

6 Months Ended

Jun. 30, 2012

Derivatives and Risk Management

13. Derivatives and Risk Management

The Partnership is exposed to various market risks, including volatility in crude oil and refined product prices, counterparty credit risk and interest rate risk. In order to manage such exposure, the Partnership’s policy is to (i) only purchase crude oil and refined products for which sales contracts have been executed or for which ready markets exist, (ii) structure sales contracts so that price fluctuations do not materially impact the margins earned, and (iii) not 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 temporary physical inventory builds or draws do occur, the Partnership continuously manages the variances to a balanced position over a period of time. Pursuant to the Partnership’s approved risk management policy, derivative contracts may be used to hedge or reduce exposure to price risk associated with acquired inventory or forecasted physical transactions.

Price Risk Management

The Partnership is exposed to risks associated with changes in the market price of crude oil and refined products as a result of the forecasted purchase or sale of these products. 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. The physical contracts related to the Partnership’s crude oil and refined products businesses that qualify as derivates have been designated as normal purchases and sales and are accounted for using traditional accrual accounting. The Partnership accounts for derivatives that do not qualify as normal purchases and sales at fair value. The Partnership does utilize derivatives such as swaps, futures and other derivative instruments to mitigate the risk associated with market movements in the price of refined products. 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.

While all derivative instruments utilized by the Partnership represent economic hedges, certain of these derivatives are not designated as hedges for accounting purposes. Such derivatives include certain contracts that were entered into and closed during the same accounting period and a limited number of contracts for which there is not sufficient correlation to the related items being economically hedged.

For refined product derivative contracts that are not designated as hedges for accounting purposes, all realized and unrealized gains and losses are recognized in the statement of comprehensive income during the current period. For refined product derivative contracts that are designated and qualify as cash flow hedges, the portion of the gain or loss on the derivative contract that is effective in offsetting the variable cash flows associated with the hedged forecasted transaction is reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transaction affects 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), is recognized in earnings during the current period. All realized gains and losses associated with refined product derivative contracts are recorded in earnings in the same line item as the forecasted transaction being hedged, either sales and other operating revenue or cost of products sold and operating expenses.

The Partnership had open derivative positions of approximately 3.0 and 1.5 million barrels of refined products at June 30, 2012 and December 31, 2011, respectively. The derivatives outstanding as of June 30, 2012 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 June 30, 2012 and December 31, 2011, the fair values of the Partnership’s derivative assets and liabilities were:


	June 30, 2012			December 31, 2011
	(in millions)
Derivative assets	$	20		$	6
Derivative liabilities		(24	)		(2	)

	$	(4	)	$	4

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

The Partnership’s derivative positions are comprised primarily of commodity contracts. The following tables set forth the impact of derivatives on the Partnership’s financial performance for the three and six months ended June 30, 2012 and 2011:

Credit Risk Management

The Partnership faces counterparty credit risk as a result of our use of financial derivative contracts. 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, in that the counterparties may be similarly affected by changes in economic, regulatory or other conditions.

The Partnership maintains credit policies with regard to its counterparties that management believes minimize the overall credit risk. 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 manages its exposure to derivative counterparty credit risk through credit analysis, credit approvals, credit limits, and monitoring procedures. At June 30, 2012 and December 31, 2011, 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 June 30, 2012, the Partnership had $111 million of consolidated variable-rate borrowings under its revolving credit facilities. This includes $5 million of outstanding borrowings on West Texas Gulf’s revolving credit facility.

Fair Value Measurements

6 Months Ended

Jun. 30, 2012

Fair Value Measurements

14. Fair Value Measurements

The Partnership applies fair value accounting for all financial assets and liabilities that are required to be measured at fair value under current accounting rules, primarily derivatives. The assets and liabilities that are measured at fair value on a recurring basis are not material to the Partnership’s condensed consolidated balance sheets.

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 financial instruments has been determined based on the Partnership’s assessment of available market information and appropriate valuation methodologies. The Partnership’s current assets (other than derivatives and inventories) and current liabilities 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 13). The estimated fair values of the Senior Notes are determined using observable market prices, as these notes are actively traded. The estimated aggregate fair value of the Senior Notes at June 30, 2012 is $1.56 billion, compared to the carrying amount of $1.45 billion. The estimated aggregate fair value of the Senior Notes at December 31, 2011 was $1.91 billion, compared to the carrying amount of $1.70 billion.

In May 2011, the FASB issued a new accounting standard update, which amended the fair value measurement guidance and includes some enhanced disclosure requirements. The most significant change in disclosures is an expansion of the information required for level 3 measurements based on unobservable inputs. The Partnership adopted the amended guidance on January 1, 2012. The adoption of the amended guidance did not have a material impact on the Partnership’s consolidated financial statements and disclosures.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

[2]	In the first quarter 2012, the Partnership recognized a non-cash impairment charge related to a cancelled software project for the crude oil acquisition and marketing business and a refined products pipeline project in Texas. The impairment was recorded as $8 and $1 million within the Crude Oil Acquisition and Marketing and Refined Products Pipelines segments, respectively.
[3]	In the second quarter 2012, the Partnership recognized a $10 million gain on the reversal of certain regulatory obligations for tank cleaning which was expected to be performed if Sunoco's Philadelphia refinery was shut down. In July 2012, Sunoco announced its intention to form a joint venture with The Carlyle Group at its Philadelphia refinery, enabling the facility to continue operating.
