	Note 1—Organization and Basis of Consolidation and Presentation
	Organization
	Plains GP Holdings, L.P. (“PAGP”) is a Delaware limited partnership formed on July 17, 2013 to own an interest in the general partner and incentive distribution rights (“IDRs”) of Plains All American Pipeline, L.P (“PAA”), a publicly traded Delaware limited partnership. PAGP has elected to be treated as a corporation for U.S. federal income tax purposes.
	We completed our initial public offering (“IPO”) on October 21, 2013. Immediately prior to our IPO, certain owners of Plains AAP, L.P. (“AAP”) sold a portion of their interests in AAP to us, resulting in our ownership of Class A units of AAP (“AAP units”), which represent limited partnership interests in AAP. As of September 30, 2014, we owned 136,046,637 AAP units (representing an approximate 22.4% limited partner interest in AAP). AAP is a Delaware limited partnership that directly owns all of PAA’s IDRs and indirectly owns the 2% general partner interest in PAA. AAP is the sole member of PAA GP LLC (“PAA GP”), a Delaware limited liability company that directly holds the 2% general partner interest in PAA. Also, through a series of transactions prior to our IPO with Plains GP Holdings LLC (our general partner), a Delaware limited liability company, and the owners of Plains All American GP LLC (“GP LLC”), a Delaware limited liability company formed on May 2, 2001, GP LLC’s general partner interest in AAP became a non-economic interest, and we became the owner of a 100% managing member interest in GP LLC. See “Basis of Consolidation and Presentation” below for the resulting accounting impacts.
	GP LLC manages the business and affairs of PAA and AAP. Except for certain matters relating to PAA that require the approval of the limited partners of PAA, and certain matters relating to AAP that require the approval of the limited partners of AAP or of us as the sole member of GP LLC, either pursuant to the governing documents of PAA, AAP or GP LLC, or as may be required by non-waivable provisions of applicable law, GP LLC has full and complete authority, power and discretion to manage and control the business, affairs and property of PAA and AAP, to make all decisions regarding those matters and to perform any and all other acts or activities customary or incident to the management of PAA and AAP’s business, including the execution of contracts and management of litigation. GP LLC employs all domestic officers and personnel involved in the operation and management of PAA and AAP.  PAA’s Canadian officers and personnel are employed by Plains Midstream Canada ULC (“PMC”).
	PAA is a publicly traded master limited partnership that owns and operates midstream energy infrastructure and provides logistics services for crude oil, natural gas liquids (“NGL”), natural gas and refined products. The term NGL includes ethane and natural gasoline products as well as products commonly referred to as liquefied petroleum gas (“LPG”), such as propane and butane. When used in this Form 10-Q, NGL refers to all NGL products including LPG. PAA owns an extensive network of pipeline transportation, terminalling, storage and gathering assets in key crude oil and NGL producing basins and transportation corridors and at major market hubs in the United States and Canada. Our business activities are conducted through three operating segments: (i) Transportation, (ii) Facilities and (iii) Supply and Logistics. See Note 12 for further discussion of our operating segments.
	As used in this Form 10-Q and unless the context suggests otherwise (taking into account the fact that PAGP has no operating activities apart from those conducted by PAA and its subsidiaries), the terms “PAGP,” “Partnership,” “Plains,” “we,” “us,” “our,” “ours” and similar terms refer to PAGP and its consolidated subsidiaries.

	Basis of Consolidation and Presentation
	The accompanying unaudited condensed consolidated interim financial statements and notes thereto should be read in conjunction with our 2013 Annual Report on Form 10-K. The financial statements have been prepared in accordance with the instructions for interim reporting as set forth by the SEC. All adjustments (consisting only of normal recurring adjustments) that in the opinion of management were necessary for a fair statement of the results for the interim periods have been reflected.  All significant intercompany transactions have been eliminated in consolidation. Certain reclassifications have been made to information from previous years to conform to the current presentation. The condensed consolidated balance sheet data as of December 31, 2013 was derived from audited financial statements, but does not include all disclosures required by GAAP. The results of operations for the three and nine months ended September 30, 2014 should not be taken as indicative of results to be expected for the entire year. These financials include PAGP and all of our wholly owned subsidiaries and those entities that we control. Under GAAP, we consolidate PAA, AAP and GP LLC. Amounts associated with the interests in these entities not owned by us are reflected in our results of operations as net income attributable to noncontrolling interests and in our balance sheet partners’ capital section as noncontrolling interests.
	For periods prior to our IPO, the accompanying condensed consolidated financial statements reflect the financial statements of GP LLC, the predecessor of PAGP, and are based on the historical ownership percentages of GP LLC and AAP. These financial statements, to the extent they relate to periods prior to our IPO, have been prepared from the separate financial records maintained by GP LLC and may not necessarily be indicative of the actual results of operations that might have occurred if PAGP had operated separately during those periods.
	Subsequent events have been evaluated through the financial statements issuance date and have been included in the following footnotes where applicable.

	Note 2—Recent Accounting Pronouncements
	Other than as discussed below and in our 2013 Annual Report on Form 10-K, no new accounting pronouncements have become effective or have been issued during the nine months ended September 30, 2014 that are of significance or potential significance to us.
	In May 2014, the FASB issued guidance regarding the recognition of revenue from contracts with customers with the underlying principle that an entity will recognize revenue to reflect amounts expected to be received in exchange for the provision of goods and services to customers upon the transfer of those goods or services. The guidance also requires additional disclosures about the nature, amount, timing and uncertainty of revenue and the related cash flows. This guidance becomes effective for interim and annual periods beginning after December 15, 2016 and can be adopted either with a full retrospective approach or a modified retrospective approach with a cumulative-effect adjustment as of the date of adoption. We are currently evaluating which transition approach to apply and the effect that adopting this guidance will have on our financial position, results of operations and cash flows.
	In April 2014, the FASB issued guidance that modifies the criteria under which assets to be disposed of are evaluated to determine if such assets qualify as a discontinued operation and requires new disclosures for both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. This guidance is effective prospectively for annual and interim reporting periods beginning after December 15, 2014. Early adoption is permitted but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issue. We are currently evaluating the provisions of this authoritative guidance and assessing its impact, but do not believe our adoption will have a material impact on our financial position, results of operations or cash flows.
	In March 2013, the FASB issued guidance regarding the release of cumulative translation adjustments into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity. This guidance became effective for interim and annual periods beginning after December 15, 2013. We adopted this guidance on January 1, 2014. Our adoption did not have a material impact on our financial position, results of operations or cash flows.

Accounts_Receivable

Accounts Receivable	'
Accounts Receivable	'
	Note 3—Accounts Receivable
	Our accounts receivable are primarily from purchasers and shippers of crude oil and, to a lesser extent, purchasers of NGL and natural gas storage. These purchasers include, but are not limited to, refiners, producers, marketing and trading companies and financial institutions that are active in the physical and financial commodity markets. The majority of our accounts receivable relate to our crude oil supply and logistics activities that can generally be described as high volume and low margin activities, in many cases involving exchanges of crude oil volumes.
	To mitigate credit risk related to our accounts receivable, we have in place a rigorous credit review process.  We closely monitor market conditions in order to make a determination with respect to the amount, if any, of credit to be extended to any given customer and the form and amount of financial performance assurances we require. Such financial assurances are commonly provided to us in the form of advance cash payments, standby letters of credit or parental guarantees. As of September 30, 2014 and December 31, 2013, we had received $181 million and $117 million, respectively, of advance cash payments from third parties to mitigate credit risk. Furthermore, as of September 30, 2014 and December 31, 2013, we had received $278 million and $426 million, respectively, of standby letters of credit to support obligations due from third parties, a portion of which applies to future business. In addition, in an effort to mitigate credit risk, a significant portion of our transactions with counterparties are settled on a net-cash basis. Further, we enter into netting agreements (contractual agreements that allow us to offset receivables and payables with those counterparties against each other on our balance sheet) for a majority of such arrangements.
	We review all outstanding accounts receivable balances on a monthly basis and record a reserve for amounts that we expect will not be fully recovered. We do not apply actual balances against the reserve until we have exhausted substantially all collection efforts. At September 30, 2014 and December 31, 2013, substantially all of our accounts receivable (net of allowance for doubtful accounts) were less than 30 days past their scheduled invoice date. Our allowance for doubtful accounts receivable totaled $4 million and $5 million at September 30, 2014 and December 31, 2013, respectively. Although we consider our allowance for doubtful accounts receivable to be adequate, actual amounts could vary significantly from estimated amounts.

	(1)                 Price per unit of measure is comprised of a weighted average associated with various grades, qualities and locations. Accordingly, these prices may not coincide with any published benchmarks for such products.
	At the end of each reporting period, we assess the carrying value of our inventory and make any adjustments necessary to reduce the carrying value to the applicable net realizable value. We did not record any such charges during the three months ended September 30, 2014. We recorded a charge of $37 million during the nine months ended September 30, 2014 related to the writedown of our natural gas inventory that was purchased in conjunction with managing natural gas storage deliverability requirements during the extended period of severe cold weather in the first quarter of 2014. During the three and nine months ended September 30, 2013, we recorded a charge of $7 million, primarily related to the writedown of our crude oil inventory due to declines in prices during the period. These adjustments are a component of “Purchases and related costs” on our accompanying condensed consolidated statements of operations. The recognition of the adjustment in 2013 was substantially offset by the recognition of gains on derivative instruments being utilized to hedge the future sales of our crude oil inventory. Substantially all of such gains were recorded to “Supply and Logistics segment revenues” on our accompanying condensed consolidated statements of operations. See Note 10 for discussion of our derivatives and risk management activities.

	(1)                   PAA commercial paper notes are backstopped by the PAA senior unsecured revolving credit facility and the PAA senior secured hedged inventory facility, which mature in August 2019 and August 2017, respectively; as such, any borrowings under the PAA commercial paper program effectively reduce the available capacity under these facilities. At September 30, 2014 and December 31, 2013, we classified $423 million and approximately $1.1 billion, respectively, of borrowings under the PAA commercial paper program as short-term. These borrowings are primarily designated as working capital borrowings, must be repaid within one year and are primarily for hedged NGL and crude oil inventory and NYMEX and ICE margin deposits.
	(2)                   In September 2014, AAP extended the maturity dates of its term loan and senior secured revolving credit facility. See “Credit Facilities” below for further discussion.
	(3)                   PAA’s fixed-rate senior notes (including current maturities) had a face value of approximately $8.2 billion and $6.7 billion at September 30, 2014 and December 31, 2013, respectively. We estimated the aggregate fair value of these notes as of September 30, 2014 and December 31, 2013 to be approximately $8.8 billion and $7.2 billion, respectively. PAA’s fixed-rate senior notes are traded among institutions, and these trades are routinely published by a reporting service. Our determination of fair value is based on reported trading activity near quarter end. We estimate that the carrying value of outstanding borrowings under the credit facilities and the PAA commercial paper program approximates fair value as interest rates reflect current market rates. The fair value estimates for the PAA senior notes, the credit facilities and the PAA commercial paper program are based upon observable market data and are classified within Level 2 of the fair value hierarchy. See Note 10 for additional discussion of the fair value hierarchy.
	Credit Facilities
	In August 2014, PAA extended the maturity dates of its senior secured hedged inventory facility and senior unsecured revolving credit facility by one year through the exercise of the option included in the current credit agreements. The PAA senior secured hedged inventory facility and the PAA senior unsecured revolving credit facility now mature in August 2017 and August 2019, respectively.
	In September 2014, AAP extended the maturity dates of its term loan and senior secured revolving credit facility by one year through the exercise of the option included in the current credit agreement. The AAP term loan and AAP senior secured revolving credit facility now mature in September 2019.
	Borrowings and Repayments
	Total borrowings under credit agreements and the PAA commercial paper program for the nine months ended September 30, 2014 and 2013 were approximately $55.7 billion and $13.2 billion, respectively. Total repayments under credit agreements and the PAA commercial paper program for the nine months ended September 30, 2014 and 2013 were approximately $56.3 billion and $13.4 billion, respectively. The variance in total gross borrowings and repayments is impacted by various business and financial factors including, but not limited to, the timing, average term and method of general partnership borrowing activities.
	Letters of Credit
	In connection with our supply and logistics activities, we provide certain suppliers with irrevocable standby letters of credit to secure our obligation for the purchase of crude oil, NGL and natural gas. Additionally, we issue letters of credit to support insurance programs and construction activities. At September 30, 2014 and December 31, 2013 we had outstanding letters of credit of $66 million and $41 million, respectively.
	PAA Senior Notes Issuances
	On April 23, 2014, PAA completed the issuance of $700 million, 4.70% senior notes due 2044 at a public offering price of 99.734%. Interest payments are due on June 15 and December 15 of each year, commencing on December 15, 2014. In anticipation of the issuance of these senior notes, PAA entered into $250 million notional principal amount of U.S. treasury locks in March and April 2014 to hedge the treasury rate portion of the interest rate on a portion of the notes. PAA terminated these treasury locks in April 2014. See Note 10 for additional disclosure.
	On September 9, 2014, PAA completed the issuance of $750 million, 3.60% senior notes due 2024 at a public offering price of 99.842%. Interest payments are due on May 1 and November 1 of each year, commencing on May 1, 2015.
	PAA Commercial Paper Program
	Effective October 20, 2014, the maximum aggregate borrowing capacity under the PAA commercial paper program was increased from $1.5 billion to $3.0 billion.

Net Income Per Class A Share	'
Net Income Per Class A Share	'
	Note 7—Net Income Per Class A Share
	Basic net income per Class A share is determined by dividing net income attributable to PAGP by the weighted average number of outstanding Class A shares during the period. Class B shares do not share in the earnings of the Partnership. Accordingly, basic and diluted net income per Class B share has not been presented.
	Diluted net income per Class A share is determined by dividing net income attributable to PAGP by the weighted average number of outstanding diluted Class A shares during the period. For purposes of calculating diluted net income per Class A share, both the net income attributable to PAGP and the weighted average number of outstanding diluted Class A shares consider the impact of possible future exchanges of (i) AAP units and the associated Class B shares into our Class A shares and (ii) certain Class B units of AAP (referred to herein as “AAP Management Units”) into our Class A shares. In addition, the calculation of the weighted average number of outstanding diluted Class A shares considers the effect of potentially dilutive awards under the Plains GP Holdings, L.P. Long-Term Incentive Plan (the “PAGP LTIP”).
	All AAP Management Units that have satisfied the applicable performance condition are considered potentially dilutive. Exchanges of potentially dilutive AAP units and AAP Management Units are assumed to have occurred at the beginning of the period and the incremental income attributable to PAGP resulting from the assumed exchanges is representative of the incremental income that would have been attributable to PAGP if the assumed exchanges occurred on that date. Our PAGP LTIP awards that contemplate the issuance of Class A Shares are considered dilutive unless (i) vesting occurs only upon the satisfaction of a performance condition and (ii) that performance condition has yet to be satisfied. PAGP LTIP awards that are deemed to be dilutive are reduced by a hypothetical share repurchase based on the remaining unamortized fair value, as prescribed by the treasury stock method in guidance issued by FASB. All outstanding PAGP LTIP awards as of September 30, 2014 are dilutive.
	For the three and nine months ended September 30, 2014, the possible exchange of any AAP units and certain AAP Management Units would have had an antidilutive effect on net income per Class A share. For the same periods, our PAGP LTIP awards are dilutive; however, there are less than 0.1 million dilutive LTIP awards, which amount is not large enough to change the presentation of weighted average shares outstanding or net income per Class A share. The following table illustrates the calculation of basic net income per Class A share and diluted net income per Class A share for the three and nine months ended September 30, 2014 (in millions, except per share data):

	Exchange Rights. Holders of AAP units and their permitted transferees each have the right to exchange all or a portion of their AAP units for Class A shares at an exchange ratio of one Class A share for each AAP unit exchanged (referred to herein as their “Exchange Right”). This Exchange Right may be exercised only if, simultaneously therewith, an equal number of Class B shares and general partner units are transferred by the exercising party to us. For additional information regarding Exchange Rights, see Note 10 to our Consolidated Financial Statements included in Part IV of our 2013 Annual Report on Form 10-K. During the nine months ended September 30, 2014, certain holders of AAP units and their permitted transferees exercised their Exchange Right, which resulted in the exchange of AAP units, general partner units and our Class B shares for our Class A shares.

	We refer to the PAGP LTIP, PAA LTIPs and AAP Management Units collectively as our “Equity-indexed compensation plans.” For additional discussion of our equity-indexed compensation plans and awards, see Note 15 to our Consolidated Financial Statements included in Part IV of our 2013 Annual Report on Form 10-K.
	In connection with our IPO in October 2013, our general partner adopted the PAGP LTIP, which is intended to align the interests of employees and directors with those of our shareholders by providing such employees and directors incentive compensation awards that reward achievement of targeted distribution levels and other business objectives. The PAGP LTIP provides for awards of options, restricted shares, phantom shares and share appreciation rights. Certain awards may also include distribution equivalent rights (“DERs”), which, subject to applicable vesting criteria, entitle the grantee to a cash payment equal to the cash distribution paid on an outstanding Class A share. The PAGP LTIP authorizes the issuance of up to 10 million Class A shares deliverable upon vesting. In February 2014, an aggregate of 83,200 phantom Class A shares were issued to our directors, resulting in expense of approximately $1 million for the nine months ended September 30, 2014.  These awards will vest annually in 25% increments, beginning in February 2015, and have an automatic re-grant feature such that as they vest, an equivalent amount is granted.
	Equity-indexed compensation activity for PAA and PAGP LTIP awards is summarized in the following table (units and shares in millions):

Derivatives and Risk Management Activities	'
	Note 10—Derivatives and Risk Management Activities
	We identify the risks that underlie our core business activities and use risk management strategies to mitigate those risks when we determine that there is value in doing so.  Our policy is to use derivative instruments for risk management purposes and not for the purpose of speculating on hydrocarbon commodity (referred to herein as “commodity”) price changes.  We use various derivative instruments to (i) manage our exposure to commodity price risk as well as to optimize our profits, (ii) manage our exposure to interest rate risk and (iii) manage our exposure to currency exchange rate risk.  Our commodity risk management policies and procedures are designed to help ensure that our hedging activities address our risks by monitoring our derivative positions, as well as physical volumes, grades, locations, delivery schedules and storage capacity.  Our interest rate and currency exchange rate risk management policies and procedures are designed to monitor our derivative positions and ensure that those positions are consistent with our objectives and approved strategies.  When we apply hedge accounting, our policy is to formally document all relationships between hedging instruments and hedged items, as well as our risk management objectives for undertaking the hedge.  This process includes specific identification of the hedging instrument and the hedged transaction, the nature of the risk being hedged and how the hedging instrument’s effectiveness will be assessed.  Both at the inception of the hedge and on an ongoing basis, we assess whether the derivatives used in a transaction are highly effective in offsetting changes in cash flows or the fair value of hedged items.
	Commodity Price Risk Hedging
	Our core business activities involve certain commodity price-related risks that we manage in various ways, including through the use of derivative instruments.  Our policy is to (i) only purchase inventory for which we have a market, (ii) structure our sales contracts so that price fluctuations do not materially affect our operating income and (iii) not acquire and hold physical inventory or derivatives for the purpose of speculating on commodity price changes.  The material commodity-related risks inherent in our business activities can be divided into the following general categories:
	Commodity Purchases and Sales — In the normal course of our operations, we purchase and sell commodities.  We use derivatives to manage the associated risks and to optimize profits.  As of September 30, 2014, net derivative positions related to these activities included:
	·         An average of 248,700 barrels per day net long position (total of 7.7 million barrels) associated with our crude oil purchases, which was unwound ratably during October 2014 to match monthly average pricing.
	·         A net short time spread position averaging approximately 19,900 barrels per day (total of 11.5 million barrels), which hedges a portion of our anticipated crude oil lease gathering purchases through June 2016.  Our use of these derivatives does not expose us to outright price risk.
	·         An average of 15,200 barrels per day (total of 6.5 million barrels) of crude oil grade spread positions through December 2015. These derivatives allow us to lock in grade basis differentials. Our use of these derivatives does not expose us to outright price risk.
	·         A net short position of approximately 25.1 Bcf through April 2016 related to anticipated sales of natural gas inventory and base gas requirements.
	·         A net short position of approximately 12.1 million barrels through December 2015 related to the anticipated sales of our crude oil, NGL and refined products inventory.
	Pipeline Loss Allowance Oil — As is common in the pipeline transportation industry, our tariffs incorporate a loss allowance factor that is intended to offset losses due to evaporation, measurement and other losses in transit.  We utilize derivative instruments to hedge a portion of the anticipated sales of the allowance oil that is to be collected under our tariffs.  As of September 30, 2014, our PLA hedges included a net short position for an average of approximately 1,400 barrels per day (total of 1.1 million barrels) through December 2016 and a long call position of approximately 0.6 million barrels through December 2016.
	Natural Gas Processing/NGL Fractionation — As part of our supply and logistics activities, we purchase natural gas for processing and NGL mix for fractionation, and we sell the resulting individual specification products (including ethane, propane, butane and condensate).  In conjunction with these activities, we hedge the price risk associated with the purchase of the natural gas and the subsequent sale of the individual specification products.  As of September 30, 2014, we had a long natural gas position of approximately 33.3 Bcf through December 2016, a short propane position of approximately 5.4 million barrels through December 2016 and a short butane position of approximately 1.6 million barrels through December 2016.
	To the extent they qualify and we decide to make the election, all of our commodity derivatives where we elect hedge accounting are designated as cash flow hedges.  We have determined that substantially all of our physical purchase and sale agreements qualify for the normal purchase normal sale scope exception.  Physical commodity contracts that meet the definition of a derivative but are ineligible, or not designated, for the normal purchase normal sale scope exception are recorded on the balance sheet at fair value, with changes in fair value recognized in earnings.

	We use interest rate derivatives to hedge interest rate risk associated with anticipated debt issuances and outstanding debt instruments.  The derivative instruments we use to manage this risk consist primarily of interest rate swaps and treasury locks.  As of September 30, 2014, AOCI includes deferred losses of $108 million that relate to open and terminated interest rate derivatives that were designated for hedge accounting.  The terminated interest rate derivatives were cash-settled in connection with the issuance or refinancing of debt agreements.  The deferred loss related to these instruments is being amortized to interest expense over the terms of the hedged debt instruments.
	PAA has entered into forward starting interest rate swaps to hedge the underlying benchmark interest rate related to forecasted debt issuances through 2015.  The following table summarizes the terms of these forward starting interest rate swaps as of September 30, 2014 (notional amounts in millions):
	Hedged Transaction	Number and Types of		Notional			Expected		Average Rate		Accounting
		Derivatives Employed		Amount			Termination Date		Locked		Treatment
	Anticipated debt offering	10 forward starting swaps (30-year)		$	250		6/15/15		3.60%		Cash flow hedge
	In anticipation of PAA’s April 2014 issuance of senior notes, PAA entered into an aggregate of five treasury lock agreements in March and April 2014 for a combined notional amount of $250 million at a locked in rate of 3.62%. The treasury locks were designated as cash flow hedges, thus changes in fair value are deferred in AOCI.  In connection with PAA’s April 2014 senior notes issuance, these treasury locks were terminated prior to maturity for an aggregate cash payment of $7 million.  The effective portion of the treasury locks was deferred in AOCI and will be amortized to interest expense over the life of the senior notes.
	Currency Exchange Rate Risk Hedging
	Because a significant portion of our Canadian business is conducted in CAD and, at times, a portion of our debt is denominated in CAD, we use foreign currency derivatives to minimize the risk of unfavorable changes in exchange rates.  These instruments include foreign currency exchange contracts and forwards.
	As of September 30, 2014, our outstanding foreign currency derivatives include derivatives we use to (i) hedge currency exchange risk associated with USD-denominated commodity purchases and sales in Canada and (ii) hedge currency exchange risk created by the use of USD-denominated commodity derivatives to hedge commodity price risk associated with CAD-denominated commodity purchases and sales.

	Summary of Financial Impact
	We record all open derivatives on the balance sheet as either assets or liabilities measured at fair value. Changes in the fair value of derivatives are recognized currently in earnings unless specific hedge accounting criteria are met.  For derivatives that qualify as cash flow hedges, changes in fair value of the effective portion of the hedges are deferred in AOCI and recognized in earnings in the periods during which the underlying physical transactions are recognized in earnings. Derivatives that do not qualify for hedge accounting and the portion of cash flow hedges that are not highly effective in offsetting changes in cash flows of the hedged items are recognized in earnings each period.  Cash settlements associated with our derivative activities are reflected as cash flows from operating activities in our condensed consolidated statements of cash flows.
	A summary of the impact of our derivative activities recognized in earnings for the three and nine months ended September 30, 2014 and 2013 is as follows (in millions):

(1)       During the three and nine months ended September 30, 2014, all of our hedged transactions were probable of occurring. During the three months ended September 30, 2013 we reclassified losses of $2 million from AOCI to Facilities segment revenues as a result of anticipated hedged transactions that were probable of not occurring. During the nine months ended September 30, 2013, we reclassified gains of $3 million and losses of $1 million from AOCI to Supply and Logistics segment revenues and Facilities segment revenues, respectively, as a result of anticipated hedged transactions that were probable of not occurring.

Our derivative transactions are governed through ISDA (International Swaps and Derivatives Association) master agreements and clearing brokerage agreements. These agreements include stipulations regarding the right of set off in the event that we or our counterparty default on our performance obligations. If a default were to occur, both parties have the right to net amounts payable and receivable into a single net settlement between parties.
Our accounting policy is to offset derivative assets and liabilities executed with the same counterparty when a master netting arrangement exists.  Accordingly, we also offset derivative assets and liabilities with amounts associated with cash margin.  Our exchange-traded derivatives are transacted through clearing brokerage accounts and are subject to margin requirements as established by the respective exchange.  On a daily basis, our account equity (consisting of the sum of our cash balance and the fair value of our open derivatives) is compared to our initial margin requirement resulting in the payment or return of variation margin. As of September 30, 2014, we had a net broker receivable of $35 million (consisting of initial margin of $74 million reduced by $39 million of variation margin that had been returned to us).  As of December 31, 2013, we had a net broker receivable of $161 million (consisting of initial margin of $85 million increased by $76 million of variation margin that had been posted by us).
The following tables present information about derivatives and financial assets and liabilities that are subject to offsetting, including enforceable master netting arrangements at September 30, 2014 and December 31, 2013 (in millions):

As of September 30, 2014, there was a net loss of $118 million deferred in AOCI including tax effects.  The deferred net loss recorded in AOCI is expected to be reclassified to future earnings contemporaneously with (i) the earnings recognition of the underlying hedged commodity transaction or (ii) interest expense accruals associated with underlying debt instruments. Of the total net loss deferred in AOCI at September 30, 2014, we expect to reclassify a net gain of $1 million to earnings in the next twelve months.  The remaining deferred loss of $119 million is expected to be reclassified to earnings through 2045. A portion of these amounts are based on market prices as of September 30, 2014; thus, actual amounts to be reclassified will differ and could vary materially as a result of changes in market conditions.
The net deferred gain/(loss), including tax effects, recognized in AOCI for derivatives for the three and nine months ended September 30, 2014 and 2013 are as follows (in millions):
	Three Months Ended						Nine Months Ended

Total	$	(6	)	$	78		$	(57	)	$	141
At September 30, 2014 and December 31, 2013, none of our outstanding derivatives contained credit-risk related contingent features that would result in a material adverse impact to us upon any change in our credit ratings.  Although we may be required to post margin on our cleared derivatives as described above, we do not require our non-cleared derivative counterparties to post collateral with us.
Recurring Fair Value Measurements

(1)                   Derivative assets and liabilities are presented above on a net basis but do not include related cash margin deposits.
Level 1
Level 1 of the fair value hierarchy includes exchange-traded commodity derivatives such as futures and options.  The fair value of exchange-traded commodity derivatives is based on unadjusted quoted prices in active markets.
Level 2
Level 2 of the fair value hierarchy includes exchange-cleared commodity derivatives and over-the-counter commodity, interest rate and foreign currency derivatives that are traded in active markets.  In addition, it includes certain physical commodity contracts.  The fair value of these derivatives is based on broker price quotations which are corroborated with market observable inputs.
Level 3
Level 3 of the fair value hierarchy includes certain physical commodity contracts.  The fair value of our Level 3 physical commodity contracts is based on a valuation model utilizing broker-quoted forward commodity prices, and timing estimates, which involve management judgment. The significant unobservable inputs used in the fair value measurement of our Level 3 derivatives are forward prices obtained from brokers.  A significant increase or decrease in these forward prices could result in a material change in fair value to our Level 3 derivatives.
Rollforward of Level 3 Net Asset/(Liability)
The following table provides a reconciliation of changes in fair value of the beginning and ending balances for our derivatives classified as Level 3 (in millions):

Commitments and Contingencies	'
Commitments and Contingencies	'
	Note 11—Commitments and Contingencies
	Litigation
	General.  In the ordinary course of business, we are involved in various legal proceedings. To the extent we are able to assess the likelihood of a negative outcome for these proceedings, our assessments of such likelihood range from remote to probable.  If we determine that a negative outcome is probable and the amount of loss is reasonably estimable, we accrue the estimated amount.  We do not believe that the outcome of these legal proceedings, individually or in the aggregate, will have a material adverse effect on our financial condition, results of operations or cash flows.  Although we believe that our operations are presently in material compliance with applicable requirements, as we acquire and incorporate additional assets it is possible that the EPA or other governmental entities may seek to impose fines, penalties or performance obligations on us (or on a portion of our operations) as a result of any past noncompliance whether such noncompliance initially developed before or after our acquisition.
	Environmental
	General.  Although we believe that our efforts to enhance our leak prevention and detection capabilities have produced positive results, we have experienced (and likely will experience future) releases of hydrocarbon products into the environment from our pipeline, rail and storage operations. These releases can result from unpredictable man-made or natural forces and may reach surface water bodies, groundwater aquifers or other sensitive environments. Whether current or past, damages and liabilities associated with any such releases from our assets may substantially affect our business.
	At September 30, 2014, our estimated undiscounted reserve for environmental liabilities totaled $87 million, of which $13 million was classified as short-term and $74 million was classified as long-term. At December 31, 2013, our estimated undiscounted reserve for environmental liabilities totaled $93 million, of which $11 million was classified as short-term and $82 million was classified as long-term. The short- and long-term environmental liabilities referenced above are reflected in “Accounts payable and accrued liabilities” and “Other long-term liabilities and deferred credits,” respectively, on our condensed consolidated balance sheets. At September 30, 2014 and December 31, 2013, we had recorded receivables totaling $9 million and $10 million, respectively, for amounts probable of recovery under insurance and from third parties under indemnification agreements, which are predominantly reflected in “Trade accounts receivable and other receivables, net” on our condensed consolidated balance sheets.
	In some cases, the actual cash expenditures may not occur for three years or longer. Our estimates used in these reserves are based on information currently available to us and our assessment of the ultimate outcome. Among the many uncertainties that impact our estimates are the necessary regulatory approvals for, and potential modification of, our remediation plans, the limited amount of data available upon initial assessment of the impact of soil or water contamination, changes in costs associated with environmental remediation services and equipment and the possibility of existing legal claims giving rise to additional liabilities. Therefore, although we believe that the reserve is adequate, costs incurred may be in excess of the reserve and may potentially have a material adverse effect on our financial condition, results of operations or cash flows.
	Bay Springs Pipeline Release. During February 2013, we experienced a crude oil release of approximately 120 barrels on a portion of one of our pipelines near Bay Springs, Mississippi. Most of the released oil was contained within our pipeline right of way, but some of the released oil entered a nearby waterway where it was contained with booms.  The EPA has issued an administrative order requiring us to take various actions in response to the release, including remediation, reporting and other actions. We have satisfied the requirements of the administrative order; however, we may be subjected to a civil penalty. The aggregate cost to clean up and remediate the site was approximately $6 million.
	Kemp River Pipeline Release. During May and June 2013, two separate releases were discovered on our Kemp River pipeline in Northern Alberta, Canada that, in the aggregate, resulted in the release of approximately 700 barrels of condensate and light crude oil.  Clean-up and remediation activities are being conducted in cooperation with the applicable regulatory agencies.  AER’s final investigation is not complete. To date, no charges, fines or penalties have been assessed against PMC with respect to these releases; however, it is possible that fines or penalties may be assessed against PMC in the future. We estimate that the aggregate clean-up and remediation costs associated with these releases will be approximately $15 million. Through September 30, 2014, we spent approximately $8 million in connection with clean-up and remediation activities.

Operating Segments	'
	Note 12—Operating Segments
	We manage our operations through three operating segments: (i) Transportation, (ii) Facilities and (iii) Supply and Logistics. Our Chief Operating Decision Maker (our Chief Executive Officer) evaluates segment performance based on measures including segment profit and maintenance capital investment. We define segment profit as revenues and equity earnings in unconsolidated entities less (i) purchases and related costs, (ii) field operating costs and (iii) segment general and administrative expenses. Each of the items above excludes depreciation and amortization. Maintenance capital consists of capital expenditures for the replacement of partially or fully depreciated assets in order to maintain the operating and/or earnings capacity of our existing assets.

	As of November 5, 2014, PAA entered into a definitive purchase and sale agreement with Oxy that provides for PAA’s purchase of Oxy’s 50% interest in BridgeTex Pipeline Company LLC (“BridgeTex”) for $1.075 billion. BridgeTex owns a 300,000 barrel-per-day crude oil pipeline (“BridgeTex Pipeline”) that extends from Colorado City in West Texas to Texas City. The remaining 50% interest in BridgeTex is owned by Magellan Midstream Partners, L.P. (“MMP”), which is also the operator of the BridgeTex Pipeline. Contemporaneous with the purchase by PAA of Oxy’s 50% interest in BridgeTex, BridgeTex has agreed to sell the southern leg of the pipeline system which runs from Houston to Texas City (the “Texas City Leg”) to MMP, and MMP has agreed to enter into a long term capacity lease with BridgeTex pursuant to which BridgeTex shippers will have access to capacity on the Texas City Leg.
	In addition to customary closing conditions and the contemporaneous consummation of the sale of the Texas City Leg and execution of the capacity lease, PAA’s acquisition of Oxy’s 50% interest in BridgeTex is subject to the completion by us, prior to December 31, 2014, of an underwritten secondary offering pursuant to which Oxy would sell a portion of its equity interest in us. In order to facilitate such offering and the overall transaction, (i) the board of directors of our general partner has agreed to an early release of the 15-month lock-up arrangement that was originally imposed on certain of our equity owners, including Oxy, in connection with our initial public offering in October 2013, (ii) certain affiliates of Kayne Anderson Investment Management, Inc., The Energy & Minerals Group and PAA Management, L.P. have agreed to waive their participation rights in such offering and (iii) Oxy, certain affiliates of Kayne Anderson Investment Management, Inc., The Energy & Minerals Group and PAA Management, L.P. have agreed to refrain from selling any of their respective interests in us for a period of up to 90 days following such offering. If an offering is not completed prior to December 31, 2014, both PAA and Oxy have the right to terminate the purchase and sale agreement.

	(1)                   PAA commercial paper notes are backstopped by the PAA senior unsecured revolving credit facility and the PAA senior secured hedged inventory facility, which mature in August 2019 and August 2017, respectively; as such, any borrowings under the PAA commercial paper program effectively reduce the available capacity under these facilities. At September 30, 2014 and December 31, 2013, we classified $423 million and approximately $1.1 billion, respectively, of borrowings under the PAA commercial paper program as short-term. These borrowings are primarily designated as working capital borrowings, must be repaid within one year and are primarily for hedged NGL and crude oil inventory and NYMEX and ICE margin deposits.
	(2)                   In September 2014, AAP extended the maturity dates of its term loan and senior secured revolving credit facility. See “Credit Facilities” below for further discussion.
	(3)                   PAA’s fixed-rate senior notes (including current maturities) had a face value of approximately $8.2 billion and $6.7 billion at September 30, 2014 and December 31, 2013, respectively. We estimated the aggregate fair value of these notes as of September 30, 2014 and December 31, 2013 to be approximately $8.8 billion and $7.2 billion, respectively. PAA’s fixed-rate senior notes are traded among institutions, and these trades are routinely published by a reporting service. Our determination of fair value is based on reported trading activity near quarter end. We estimate that the carrying value of outstanding borrowings under the credit facilities and the PAA commercial paper program approximates fair value as interest rates reflect current market rates. The fair value estimates for the PAA senior notes, the credit facilities and the PAA commercial paper program are based upon observable market data and are classified within Level 2 of the fair value hierarchy. See Note 10 for additional discussion of the fair value hierarchy.
