Notes to Consolidated Financial Statements (Unaudited)

1. Description of the Business and Basis of Presentation

Description of the Business—MPLX LP (the “Partnership”) is a fee-based, growth-oriented master limited partnership formed to own, operate, develop and acquire pipelines and other midstream assets related to the transportation and storage of crude oil, refined products and other hydrocarbon-based products. As of September 30, 2014, the Partnership’s assets consisted of a 69 percent indirect interest in a network of common carrier crude oil and product pipeline systems and associated storage assets in the Midwest and Gulf Coast regions of the United States. The Partnership also owns a 100 percent interest in a butane cavern in Neal, West Virginia with approximately one million barrels of storage capacity.

The Partnership was formed on March 27, 2012, as a Delaware limited partnership. On October 31, 2012, the Partnership completed its initial public offering (the “Offering”) of 19,895,000 common units (including 2,595,000 common units issued pursuant to the exercise of the underwriters’ over-allotment option), representing limited partner interests. Unless the context otherwise requires, references in this report to “MPLX LP,” the “Partnership,” “we,” “our,” “us,” or like terms refer to MPLX LP and its subsidiaries, including MPLX Operations LLC (“MPLX Operations”) and MPLX Terminal and Storage LLC (“MPLX Terminal and Storage”), both wholly-owned subsidiaries, and MPLX Pipe Line Holdings LP (“Pipe Line Holdings”), of which MPLX LP owned a 69 percent general partner interest at September 30, 2014. Initially, 51 percent of Pipe Line Holdings was contributed to the Partnership. Due to subsequent acquisitions, this interest increased to 56 percent as of May 1, 2013 and 69 percent as of March 1, 2014, as discussed in Note 3. Pipe Line Holdings owns 100 percent of Marathon Pipe Line LLC (“MPL”) and Ohio River Pipe Line LLC (“ORPL”). References to “MPC” refer collectively to Marathon Petroleum Corporation and its subsidiaries, other than the Partnership.

Our operations consist of one reportable segment.

Basis of Presentation—Our financial position, results of operations and cash flows consist of consolidated MPLX LP activities and balances. All significant intercompany transactions and accounts have been eliminated.

The accompanying interim consolidated financial statements are unaudited; however, in the opinion of our management, these statements reflect all adjustments necessary for a fair statement of the results for the periods reported. All such adjustments are of a normal, recurring nature unless otherwise disclosed. These interim consolidated financial statements, including the notes, have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission applicable to interim period financial statements and do not include all of the information and disclosures required by accounting principles generally accepted in the United States (“U.S. GAAP”) for complete financial statements.

These interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2013. The results of operations for the three months and nine months ended September 30, 2014 are not necessarily indicative of the results to be expected for the full year.

In preparing our consolidated statements of equity, net income attributable to MPLX LP is allocated to unitholders in accordance with their respective ownership percentages. However, when distributions related to the incentive distribution rights are made, earnings equal to the amount of those distributions are first allocated to the general partner before the remaining earnings are allocated to the unitholders based on their respective ownership percentages. The allocation of net income attributable to MPLX LP for purposes of calculating net income per limited partner is described in Note 5.

2. Accounting Standards

Not Yet Adopted

In August 2014, the Financial Accounting Standards Board ("FASB") issued an accounting standards update requiring management to assess an entity's ability to continue as a going concern and to provide related footnote disclosures in certain circumstances. Management will be required to assess if there is substantial doubt about an entity's ability to continue as a going concern within one year after the date that the financial statements are issued. Disclosures will be required if conditions give rise to substantial doubt and the type of disclosure will be determined based on whether management's plans will be able to alleviate the substantial doubt. The accounting standards update will be effective for the first annual period ending after December 15, 2016, and for annual periods and interim periods thereafter with early application permitted.

In May 2014, FASB issued an accounting standards update for revenue recognition that is aligned with the International Accounting Standards Board's revenue recognition standard issued on the same day. The guidance in the update states that revenue is recognized when a customer obtains control of a good or service. Recognition of the revenue will involve a multiple step approach including identifying the contract, identifying the separate performance obligations, determining the transaction price, allocating the price to the performance obligations and then recognizing the revenue as the obligations are satisfied. Additional disclosures will be required to provide adequate information to understand the nature, amount, timing and uncertainty of reported revenues and revenues expected to be recognized. The accounting standards update will be effective on a retrospective or modified retrospective basis for annual reporting periods beginning after December 15, 2016, and interim periods within those years, with no early adoption permitted. At this point, a final determination has not been made as to the impact of the adoption of this standards update in the first quarter of 2017. However, we do not expect it to have a material impact on our consolidated results of operations, financial position or cash flows.

In April 2014, the FASB issued an accounting standards update that redefines the criteria for determining discontinued operations and introduces new disclosures related to these disposals. The updated definition of a discontinued operation is the disposal of a component (or components) of an entity or the classification of a component (or components) of an entity as held for sale which represents a strategic shift for an entity and has (or will have) a major impact on an entity's operations and financial results. The standard requires disclosure of additional financial information for discontinued operations and individually material components not qualifying for discontinued operation presentation, as well as information regarding an entity's continuing involvement with the discontinued operation. The accounting standards update is effective prospectively for annual periods beginning on or after December 15, 2014, and interim periods within those years. Early adoption is permitted. Adoption of this standards update in the first quarter of 2015 is not expected to have an impact on our consolidated results of operations, financial position or cash flows.

3. Acquisitions

Effective March 1, 2014, we acquired a 13 percent interest in Pipe Line Holdings from MPC for consideration of $310.0 million, which was funded with $40.0 million of cash on hand and $270.0 million of borrowings on our bank revolver. We recorded the 13 percent interest at its historical carrying value of $137.5 million and the excess cash paid over historical carrying value of $172.5 million as a decrease to general partner equity. Prior to this transaction, the 13 percent interest was held by MPC and was reflected as part of the noncontrolling interest retained by MPC in our consolidated financial statements. Beginning March 1, 2014, our consolidated financial statements reflect the 69 percent general partner interest in Pipe Line Holdings owned by MPLX LP, while the 31 percent limited partner interest held by MPC is reflected as a noncontrolling interest.

On May 1, 2013, we acquired a five percent interest in Pipe Line Holdings from MPC for consideration of $100.0 million, which was funded with cash on hand. We recorded the five percent interest in Pipe Line Holdings at its historical carrying value of $53.6 million and the excess cash paid over historical carrying value of $46.4 million as a decrease to general partner equity.

These acquisitions were accounted for on a prospective basis and the terms of the acquisitions were approved by the conflicts committee of the board of directors of our general partner, which is comprised entirely of independent directors.

Changes in MPLX LP’s equity resulting from changes in its ownership interest in Pipe Line Holdings for the three months and nine months ended September 30, 2014 and 2013 were as follows:



	Three Months Ended September 30,				Nine Months Ended September 30,
(In millions)	2014		2013		2014			2013
Net income attributable to MPLX LP	$	29.1	$	21.5	$	92.1		$	57.7
Transfer to noncontrolling interest retained by MPC:
Decrease in general partner-MPC equity for purchases of additional interest in Pipe Line Holdings	—		—		(172.5		)	(46.4		)
Change from net income attributable to MPLX LP and transfer to noncontrolling interest retained by MPC	$	29.1	$	21.5	$	(80.4	)	$	11.3

4. Related Party Agreements and Transactions

Our related parties include:


•	MPC, which refines, markets and transports crude oil and petroleum products, primarily in the Midwest, Gulf Coast, East Coast and Southeast regions of the United States.


•	Centennial Pipeline LLC (“Centennial”), in which MPC has a 50 percent interest. Centennial owns a products pipeline and storage facility.


•	Muskegon Pipeline LLC (“Muskegon”), in which MPC has a 60 percent noncontrolling interest. Muskegon owns a common carrier products pipeline.

Related Party Agreements

We have various long-term, fee-based commercial agreements with MPC under which we provide pipeline transportation and storage services to MPC, and MPC has committed to provide us with minimum quarterly throughput and storage volumes of crude oil and refined products and minimum storage volumes of butane. For detailed descriptions of our commercial and other agreements with MPC, see Item 1. Business in our Annual Report on Form 10-K for the year ended December 31, 2013.

On March 31, 2014, Pipe Line Holdings entered into a credit agreement with MPL Investment LLC, a subsidiary of MPC, providing for a $50.0 million revolving credit facility which is scheduled to terminate on March 31, 2019. The agreement requires that we remain in compliance with the covenants, terms and conditions to which we are subject under our bank revolving credit agreement. This facility allows more efficient use of our bank revolving credit agreement. Borrowings of revolving loans under this credit facility bear interest at the one-month term LIBO Rate plus 1.375 percent. As of September 30, 2014, there were no borrowings outstanding under this facility.

We believe the terms and conditions under our agreements with MPC are generally comparable to those with unrelated parties.

Related Party Transactions

Sales to related parties were as follows:

Under our transportation services agreements, if MPC fails to transport its minimum throughput volumes during any quarter, then MPC will pay us a deficiency payment equal to the volume of the deficiency multiplied by the tariff rate then in effect. The deficiency amounts are recorded as deferred revenue-related parties. MPC may then apply the amount of any such deficiency payments as a credit for volumes transported on the applicable pipeline system in excess of its minimum volume commitment during the following four or eight quarters under the terms of the applicable transportation services agreement. We recognize revenues for the deficiency payments when credits are used for volumes transported in excess of minimum quarterly volume commitments, when it becomes impossible to physically transport volumes necessary to utilize the credits or upon the expiration of the applicable four or eight quarter period. The use or expiration of the credits is a decrease in deferred revenue-related parties.

During the nine months ended September 30, 2014 and 2013, MPC did not ship its minimum committed volumes on certain of our pipeline systems. The resulting deficiencies were related to transportation services agreements which have four quarter make-up periods. In addition, capital projects we are undertaking at the request of MPC are reimbursed in cash and recognized in income over the remaining term of the applicable transportation services agreements. The deferred revenue-related parties balance associated with the minimum volume deficiencies and project reimbursements were as follows:



(In millions)	September 30, 2014		December 31, 2013
Minimum volume deficiencies - MPC	$	29.5	$	34.0
Project reimbursements - MPC	4.8		—
Total	$	34.3	$	34.0

5. Net Income Per Limited Partner Unit

Net income per unit applicable to common limited partner units and to subordinated limited partner units is computed by dividing the respective limited partners’ interest in net income attributable to MPLX LP by the weighted average number of common units and subordinated units outstanding. Because we have more than one class of participating securities, we use the two-class method when calculating the net income per unit applicable to limited partners. The classes of participating securities include common units, subordinated units, general partner units, certain equity-based compensation awards and incentive distribution rights.

Cash distributions - Our partnership agreement sets forth the calculation to be used to determine the amount and priority of cash distributions that the common and subordinated unitholders and general partner will receive. In accordance with our partnership agreement, on October 21, 2014, we declared a quarterly cash distribution of $0.3575 per unit, totaling $27.9 million. This distribution will be paid on November 14, 2014 to unitholders of record on November 4, 2014.

The allocation of total quarterly cash distributions to general and limited partners is as follows for the three and nine months ended September 30, 2014 and 2013. Our distributions are declared subsequent to quarter end; therefore, the following table represents total cash distributions applicable to the period in which the distributions were earned.

8. Income Taxes

We are not a taxable entity for United States federal income tax purposes or for the majority of states that impose an income tax. Taxes on our net income generally are borne by our partners through the allocation of taxable income. Our income tax provision results from partnership activity in the states of Kentucky, Tennessee and Texas.

Our income tax provision was less than $0.1 million and $0.4 million for the three months ended September 30, 2014 and 2013 and $0.1 million and $0.5 million for the nine months ended September 30, 2014 and 2013. Our effective tax rate was less than 0.1 percent and 1.0 percent for the three months ended September 30, 2014 and 2013 and 0.1 percent and 0.5 percent for the nine months ended September 30, 2014 and 2013.

As of September 30, 2014 and December 31, 2013, we had unrecognized tax benefits of less than $0.1 million.

10. Fair Value Measurements

Fair Values—Recurring

There were no assets accounted for at fair value on a recurring basis at September 30, 2014 and December 31, 2013.

Fair Values—Reported

Our primary financial instruments are trade receivables and payables. We believe the carrying values of our current assets and liabilities approximate fair value. Our fair value assessment incorporates a variety of considerations, including (1) the short-term duration of the instruments, (2) MPC’s investment-grade credit rating and (3) our historical incurrence of and expected future insignificance of bad debt expense, which includes an evaluation of counterparty credit risk. Fair value of our variable-rate long-term debt approximates the carrying value. The following table summarizes the fair value and carrying value of our long-term debt, excluding capital leases, at September 30, 2014 and December 31, 2013.



	September 30, 2014				December 31, 2013
(In millions)	Fair Value		Carrying Value		Fair Value		Carrying Value
Long-term debt	$	255.3	$	255.0	$	—	$	—

11. Debt

Our outstanding borrowings at September 30, 2014 and December 31, 2013 consisted of the following:



(In millions)	September 30, 2014		December 31, 2013
MPLX Operations - bank revolving credit agreement due 2017	$	255.0	$	—
MPL - capital lease obligations due 2020	10.0		10.5
Total	265.0		10.5
Amounts due within one year	0.8		0.7
Total long-term debt due after one year	$	264.2	$	9.8

On March 31, 2014, Pipe Line Holdings entered into a credit agreement with MPL Investment LLC, a subsidiary of MPC. As of September 30, 2014, there were no borrowings outstanding under this facility. A description of this agreement is discussed in detail in Note 4.

During the nine months ended September 30, 2014, we borrowed $270.0 million under our bank revolving credit agreement, at an average interest rate of 1.5 percent, per annum, and repaid $15.0 million of those borrowings. The borrowing was used to fund our acquisition of the additional interest in Pipe Line Holdings on March 1, 2014. At September 30, 2014, we had $255.0 million of borrowings and no letters of credit outstanding under the bank revolving credit agreement, resulting in a total unused revolving credit availability of $245.0 million, or 49.0 percent of the borrowing capacity. The bank revolving credit agreement is scheduled to mature on October 31, 2017.

14. Commitments and Contingencies

We are the subject of, or a party to, a number of pending or threatened legal actions, contingencies and commitments involving a variety of matters, including laws and regulations relating to the environment. Some of these matters are discussed below. For matters for which we have not recorded an accrued liability, we are unable to estimate a range of possible losses for the reasons discussed in more detail below. However, the ultimate resolution of some of these contingencies could, individually or in the aggregate, be material.

Environmental matters—We are subject to federal, state and local laws and regulations relating to the environment. These laws generally provide for control of pollutants released into the environment and require responsible parties to undertake remediation of hazardous waste disposal sites. Penalties may be imposed for noncompliance.

At September 30, 2014 and December 31, 2013, accrued liabilities for remediation totaled $1.0 million and $1.1 million, respectively. At September 30, 2014 and December 31, 2013, it is reasonably possible that an estimated loss existed of up to $0.4 million in excess of the amount accrued for remediation. However, it is not presently possible to estimate the ultimate amount of all remediation costs that might be incurred or penalties, if any, which may be imposed. Receivables from MPC for indemnification of environmental costs related to incidents occurring prior to the Offering were $0.1 million and $0.3 million at September 30, 2014 and December 31, 2013, respectively.

Legal Proceedings—In 2003, the State of Illinois brought an action against the Premcor Refining Group, Inc. (“Premcor”) and Apex Refining Company (“Apex”) asserting claims for environmental cleanup related to the refinery owned by these entities in the Hartford/Wood River, Illinois area. In 2006, Premcor and Apex filed third-party complaints against numerous owners and operators of petroleum products facilities in the Hartford/Wood River, Illinois area, including MPL. These complaints, which have been amended since filing, assert claims of common law nuisance and contribution under the Illinois Contribution Act and other laws for environmental cleanup costs that may be imposed on Premcor and Apex by the State of Illinois. There are several third-party defendants in the litigation and MPL has asserted cross-claims in contribution against the various third-party defendants. This litigation is currently pending in the Third Judicial Circuit Court, Madison County, Illinois. While the ultimate outcome of these litigated matters remains uncertain, neither the likelihood of an unfavorable outcome nor the ultimate liability, if any, with respect to this matter can be determined at this time and we are unable to estimate a reasonably possible loss (or range of loss) for this litigation. Under our omnibus agreement, MPC will indemnify us for the full cost of any losses should MPL be deemed responsible for any damages in this lawsuit.

Guarantees—We have entered into guarantees with maximum potential undiscounted payments totaling $1.7 million as of September 30, 2014, which consist of leases of vehicles that contain general lease indemnities and guaranteed residual values.

Over the years, we have sold various assets in the normal course of our business. Certain of the related agreements contain performance and general guarantees, including guarantees regarding inaccuracies in representations, warranties, covenants and agreements, and environmental and general indemnifications that require us to perform upon the occurrence of a triggering event or condition. These guarantees and indemnifications are part of the normal course of selling assets. We are typically not able to calculate the maximum potential amount of future payments that could be made under such contractual provisions because of the variability inherent in the guarantees and indemnities. Most often, the nature of the guarantees and indemnities is such that there is no appropriate method for quantifying the exposure because the underlying triggering event has little or no past experience upon which a reasonable prediction of the outcome can be based.

Contractual commitments—At September 30, 2014, our contractual commitments to acquire property, plant and equipment totaled $29.2 million. Our contractual commitments at September 30, 2014 were primarily related to a tank expansion project in Patoka, Illinois and other pipeline related projects.

PARTNERSHIP OVERVIEW

The Partnership was formed on March 27, 2012, as a Delaware limited partnership. On October 31, 2012, the Partnership completed its initial public offering (the “Offering”) of 19,895,000 common units (including 2,595,000 common units issued pursuant to the exercise of the underwriters’ over-allotment option), representing limited partner interests. Unless the context otherwise requires, references in this report to “MPLX LP,” the “Partnership,” “we,” “our,” “us,” or like terms refer to MPLX LP and its subsidiaries, including MPLX Operations LLC (“MPLX Operations”) and MPLX Terminal and Storage LLC (“MPLX Terminal and Storage”), both wholly-owned subsidiaries, and MPLX Pipe Line Holdings LP (“Pipe Line Holdings”), of which MPLX LP owned a 69 percent general partner interest at September 30, 2014. Pipe Line Holdings owns 100 percent of Marathon Pipe Line LLC (“MPL”) and Ohio River Pipe Line LLC (“ORPL”). References to “MPC” refer collectively to Marathon Petroleum Corporation and its subsidiaries, other than the Partnership.

We are a fee-based, growth-oriented master limited partnership formed by MPC to own, operate, develop and acquire pipelines and other midstream assets related to the transportation and storage of crude oil, refined products and other hydrocarbon-based products. We believe our network of petroleum pipelines is one of the largest in the United States, based on total annual volumes delivered. Our assets are integral to the success of MPC’s operations. As of September 30, 2014, our primary assets consisted of:


•	a 69 percent general partner interest in Pipe Line Holdings, an entity that owns 100 percent interest in MPL and ORPL, which in turn collectively own:


•	a network of pipeline systems that includes approximately 1,004 miles of common carrier crude oil pipelines and approximately 1,902 miles of common carrier product pipelines extending across nine states. This network includes approximately 230 miles of common carrier crude oil and product pipelines that we operate under long-term leases with third parties;


•	a barge dock located on the Mississippi River near Wood River, Illinois with approximately 84 thousand barrels per day (mbpd) of crude oil and product throughput capacity; and


•	crude oil and product tank farms located in Patoka, Wood River and Martinsville, Illinois and Lebanon, Indiana.


•	a 100 percent interest in a butane cavern located in Neal, West Virginia with approximately one million barrels of storage capacity that serves MPC’s Catlettsburg, Kentucky refinery.

As the sole general partner of Pipe Line Holdings, we control all aspects of management of Pipe Line Holdings, including its cash distribution policy. On May 1, 2013, we acquired a five percent interest in Pipe Line Holdings from MPC for consideration of $100.0 million in cash, increasing our ownership interest to 56 percent. The purchase was financed with cash on hand.

Effective March 1, 2014, we acquired a 13 percent interest in Pipe Line Holdings from MPC for consideration of $310.0 million, bringing our ownership to 69 percent. This purchase was financed with $40.0 million of cash on hand and $270.0 million of borrowings on our bank revolver.

HOW WE EVALUATE OUR OPERATIONS

Our management uses a variety of financial and operating metrics to analyze our performance. These metrics are significant factors in assessing our operating results and profitability and include the non-U.S. GAAP financial measures of Adjusted EBITDA and Distributable Cash Flow.

We define Adjusted EBITDA as net income before depreciation, provision (benefit) for income taxes, non-cash equity-based compensation and net interest and other financial costs. We also use Distributable Cash Flow, which we define as Adjusted EBITDA plus the current period deferred revenue for committed volume deficiencies less net interest and other financial costs, income taxes paid, maintenance capital expenditures paid and volume deficiency credits.

Under our transportation services agreements, if MPC fails to transport its minimum throughput volumes during any quarter, then MPC will pay us a deficiency payment equal to the volume of the deficiency multiplied by the tariff rate then in effect. The deficiency amounts are recorded as an increase in deferred revenue for committed volume deficiencies and included in the calculation of Distributable Cash Flow. The deficiencies are not included in Adjusted EBITDA for the period in which they occurred. MPC may then apply the amount of any such deficiency payments as a credit for volumes transported on the applicable pipeline system in excess of its minimum volume commitment during the following four quarters or eight quarters under the terms of the applicable transportation services agreement. We recognize revenues for the deficiency payments when credits are used for volumes transported in excess of minimum quarterly volume commitments, when it becomes impossible to physically transport volumes necessary to utilize the credits or upon the expiration of the applicable four or eight quarter period. When credits are used, expire or can no longer be utilized, the associated revenue is included within Adjusted EBITDA and is also reflected as a decrease in the calculation of Distributable Cash Flow.

Adjusted EBITDA and Distributable Cash Flow are non-U.S. GAAP supplemental financial measures that management and external users of our consolidated financial statements, such as industry analysts, investors, lenders and rating agencies, may use to assess:


•	our operating performance compared to other publicly traded partnerships in our industry, without regard to historical cost basis or, in the case of Adjusted EBITDA, financing methods;


•	the ability of our assets to generate sufficient cash flow to make distributions to our unitholders;


•	our ability to incur and service debt and fund capital expenditures; and


•	the viability of acquisitions and other capital expenditure projects and the returns on investment of various investment opportunities.

We believe that the presentation of Adjusted EBITDA and Distributable Cash Flow provides useful information to investors in assessing our financial condition and results of operations. The U.S. GAAP measures most directly comparable to Adjusted EBITDA and Distributable Cash Flow are net income and net cash provided by operating activities. Adjusted EBITDA and Distributable Cash Flow should not be considered as alternatives to U.S. GAAP net income or net cash provided by operating activities. Adjusted EBITDA and Distributable Cash Flow have important limitations as analytical tools because they exclude some but not all items that affect net income and net cash provided by operating activities or any other measure of financial performance or liquidity presented in accordance with U.S. GAAP. Adjusted EBITDA and Distributable Cash Flow should not be considered in isolation or as substitutes for analysis of our results as reported under U.S. GAAP. Additionally, because Adjusted EBITDA and Distributable Cash Flow may be defined differently by other companies in our industry, our definitions of Adjusted EBITDA and Distributable Cash Flow may not be comparable to similarly titled measures of other companies, thereby diminishing their utility.

For a reconciliation of Adjusted EBITDA and Distributable Cash Flow to their most comparable measures calculated and presented in accordance with U.S. GAAP, see – Results of Operations.

⁽¹⁾Starting in the third quarter of 2014, net interest and other financial costs is used to calculate Distributable Cash Flow attributable to MPLX LP instead of cash interest paid, net. All prior periods presented have been recalculated to reflect a consistent approach. Previously, Distributable Cash Flow attributable to MPLX LP was $31.1 million in the third quarter of 2013 and $86.3 million for the first nine months of 2013.

Table of Contents

Sales and other operating revenues decreased $3.8 million in the third quarter of 2014 compared to the third quarter of 2013. This variance was primarily due to a $4.3 million decrease related to a 53 mbpd reduction in third-party crude oil and products volumes shipped, offset by a $0.4 million increase resulting from higher average tariffs received on the volumes of crude oil and products shipped.

Sales and other operating revenues decreased $7.8 million in the first nine months of 2014 compared to the same period in 2013. This variance was primarily due to a $11.5 million decrease related to a 56 mbpd reduction in third-party crude oil and products volumes shipped, offset by a $3.5 million increase due to higher average tariffs received on the volumes of crude oil and products shipped.

Sales to related parties increased $16.3 million in the third quarter of 2014 compared to the third quarter of 2013. This increase was primarily related to a $6.7 million increase due to higher average tariffs received on the volumes of crude oil and products shipped and an $11.0 million increase in revenue related to volume deficiency credits, offset by a $1.6 million decrease related to a 66 mbpd reduction in related party crude oil and product volumes shipped.

Sales to related parties increased $51.8 million in the first nine months of 2014 compared to the same period in 2013. This increase was primarily related to a $19.4 million increase due to higher average tariffs received on the volumes of crude oil and products shipped and a $36.4 million increase in revenue related to volume deficiency credits, offset by a $3.2 million decrease related to a 91 mbpd reduction in related party crude oil and product volumes shipped.

Other income and other income - related parties increased $1.7 million in the third quarter and $4.5 million in the first nine months of 2014 compared to the same periods in 2013. The increases were primarily due to an increase in fees received for operating MPC’s private pipeline systems.

Cost of revenues increased $7.5 million in the third quarter and $3.7 million in the first nine months of 2014 compared to the same periods in 2013. The three and nine month variance was primarily related to an increase in contract services used.

Purchases from related parties decreased $0.1 million in the third quarter and increased $2.0 million in the first nine months of 2014 compared to the same periods in 2013. The nine month variance was primarily related to higher compensation expenses provided under the omnibus and employee services agreements with MPC.

Depreciation expense decreased $0.2 million in the third quarter and increased $1.2 million in the first nine months of 2014 compared to the same periods of 2013. The nine month variance was primarily due to completed capital projects.

General and administrative expenses increased $2.3 million in the third quarter and $6.7 million in the first nine months of 2014 compared to the same periods of 2013. The increases were primarily related to services provided under the omnibus and employee services agreements with MPC.

During both the third quarter and first nine months of 2014, MPC did not ship its minimum committed volumes on certain of our pipeline systems. As a result, for the first nine months of 2014, MPC was obligated to make a $32.4 million deficiency payment, of which $11.2 million was paid within the third quarter of 2014. We have recorded these deficiency payments as deferred revenue-related parties on our consolidated balance sheets. During the third quarter and the first nine months of 2014, there was $11.4 million and $36.9 million, respectively, of volume deficiency credits, which we have recorded as revenue. At September 30, 2014, the cumulative balance of deferred revenue-related parties on our consolidated balance sheet related to volume deficiencies was $29.5 million. The following table presents the future expiration dates of the associated deferred revenue credits:



(In millions)
December 31, 2014	$	7.7
March 31, 2015	6.8
June 30, 2015	6.9
September 30, 2015	8.1
Total	$	29.5

Table of Contents

We will recognize revenue for the deficiency payments in future periods at the earlier of when volumes are transported in excess of the minimum quarterly volume commitments, when it becomes impossible to physically transport volumes necessary to utilize the accumulated credits or upon expiration of the make-up period. However, deficiency payments are included in the determination of Distributable Cash Flow in the period in which a deficiency occurs.

GROWTH OUTLOOK

We have announced plans to substantially increase the growth rate of the partnership to build size and scale. This should provide additional capacity to take on projects and acquisition opportunities that will add to our stable and predictable fee-based cash flow business. It should also support our intention to maintain an attractive distribution growth profile over the long term. In support of these plans, the MPC board of directors has authorized the sale of MPC's remaining 31 percent interest in MPLX Pipe Line Holdings LP to MPLX. If the MPLX board of directors approves the transaction, it would be expected to be financed with a combination of debt and equity, which could include transactions with the sponsor.

LIQUIDITY AND CAPITAL RESOURCES

Cash Flows

Our cash and cash equivalents balance was $32.2 million at September 30, 2014 compared to $54.1 million at December 31, 2013. The change in cash and cash equivalents was due to the factors discussed below. Net cash provided by (used in) operating activities, investing activities and financing activities for the nine months ended September 30, 2014 and 2013 were as follows:



	Nine Months Ended September 30,
(In millions)	2014			2013
Net cash provided by (used in):
Operating activities	$	190.3		$	167.1
Investing activities	(43.1		)	(81.0		)
Financing activities	(169.1		)	(215.9		)
Total	$	(21.9	)	$	(129.8	)

Net cash provided by operating activities increased $23.2 million in the first nine months of 2014 compared to the first nine months of 2013, primarily due to a $32.4 million increase in net income, offset by a $11.9 million unfavorable impact from changes in working capital as discussed below.

For the first nine months of 2014, changes in working capital were a net $12.1 million source of cash. Net liabilities to related parties increased $7.2 million, primarily due to an increase in payables to related parties and a decrease in receivables from related parties. Third-party receivables decreased $3.3 million primarily due to lower third-party tariff revenue receivables and payments received on outstanding receivables.

For the first nine months of 2013, changes in working capital were a net $24.0 million source of cash. Net liabilities to related parties increased $16.9 million, primarily due to an increase in deferred revenue from related parties, partially offset by a decrease in payables from related parties. Third-party payables increased $2.7 million primarily due to the timing of project expenditures. Third-party receivables decreased $3.3 million primarily due to lower third-party tariff revenue receivables and payments received on outstanding receivables.

Net cash used in investing activities decreased $37.9 million in the first nine months of 2014 compared to the first nine months of 2013, primarily due to a $33.9 million decrease in additions to property, plant and equipment. Additions to property, plant and equipment of $47.1 million in the first nine months of 2014 and $81.0 million in the first nine months of 2013 were primarily due to capital expenditures.

Net cash used in financing activities decreased $46.8 million in the first nine months of 2014 compared to the first nine months of 2013. The decrease in cash used is primarily due to $255.0 million in net borrowings on our bank revolving credit agreement, partially offset by increased distributions to MPC of $210.0 million related to the acquisition of interests in Pipe Line Holdings.

Capital Resources

We expect our ongoing sources of liquidity to include cash generated from operations, borrowings under our revolving credit agreements, and issuances of additional debt and equity securities. We believe that cash generated from these sources will be sufficient to meet our short-term and long-term funding requirements, including working capital requirements, capital expenditure requirements, repayment of debt maturities and quarterly cash distributions. MPC manages our cash and cash equivalents on our behalf directly with third-party institutions as part of the treasury services that it provides to us under our omnibus agreement.

Our bank revolving credit agreement (“Credit Agreement”) contains representations and warranties, affirmative and negative covenants and events of default that we consider usual and customary for an agreement of that type and that could, among other things, limit our ability to pay distributions to our unitholders. The financial covenant requires us to maintain a ratio of Consolidated Total Debt as of the end of each fiscal quarter to Consolidated EBITDA (both as defined in the Credit Agreement) for the prior four fiscal quarters of not greater than 5.0 to 1.0 (or 5.5 to 1.0 during the six-month period following certain acquisitions). At September 30, 2014, we were in compliance with this financial covenant with a ratio of Consolidated Total Debt to Consolidated EBITDA of 1.7 to 1.0, as well as other covenants contained in the Credit Agreement. As of September 30, 2014, we had $255.0 million outstanding under the Credit Agreement.

On March 31, 2014, Pipe Line Holdings entered into a credit agreement with MPL Investment LLC, a subsidiary of MPC, providing for a $50.0 million revolving credit facility which is scheduled to terminate on March 31, 2019. This facility allows more efficient use of our aforementioned Credit Agreement. The agreement requires that we remain in compliance with the covenants, terms and conditions to which we are subject under the aforementioned Credit Agreement. Borrowings of revolving loans under this credit facility bear interest at the one-month term LIBO Rate plus 1.375 percent. As of September 30, 2014, there were no borrowings outstanding under this facility.

Capital Requirements

Our operations are capital intensive, requiring investments to expand, upgrade or enhance existing operations and to meet environmental and operational regulations. Our capital requirements consist of maintenance capital expenditures and expansion capital expenditures. Examples of maintenance capital expenditures are those made to replace partially or fully depreciated assets, to maintain the existing operating capacity of our assets and to extend their useful lives, or other capital expenditures that are incurred in maintaining existing system volumes and related cash flows. In contrast, expansion capital expenditures are those incurred for acquisitions or capital improvements that we expect will increase our operating capacity or operating income over the long term. Examples of expansion capital expenditures include the acquisition of equipment or the construction, development or acquisition of additional pipeline or storage capacity.

Our capital expenditures for the nine months ended September 30, 2014 and 2013 are shown in the table below:



	Nine Months Ended September 30,
(In millions)	2014		2013
Maintenance	$	17.4	$	15.3
Expansion	36.6		70.7
Total capital expenditures	54.0		86.0
Less: Increase in capital accruals	5.9		1.6
Asset retirement expenditures	1.0		3.4
Additions to property, plant and equipment	$	47.1	$	81.0

Our revised capital budget (including retirement expenditures) for 2014 is $110 million, relating primarily to upgrades to replace or enhance our existing facilities and projects for new infrastructure. Included in the budget is $82 million for expansion capital expenditures and $28 million for maintenance capital expenditures. The 2014 capital budget has been reduced from $148 million to $110 million due to lower than expected costs through greater procurement efficiencies than originally planned. We continuously evaluate our capital budget and make changes as conditions warrant.

We intend to pay at least the minimum quarterly distribution of $0.2625 per unit per quarter, which equates to $19.8 million per quarter, or $79.2 million per year, based on the number of common, subordinated and general partner units currently outstanding. On October 21, 2014, we announced the board of directors of our general partner had declared a distribution of $0.3575 per unit that will be paid on November 14, 2014 to unitholders of record on November 4, 2014. This represents an

Table of Contents

increase of $0.0150 per unit, or 4 percent, above the second quarter 2014 distribution of $0.3425 per unit and an increase of 20 percent over the third quarter 2013 distribution. This increase in the distribution is consistent with our intent to maintain an attractive distribution growth profile over an extended period of time. Although our partnership agreement requires that we distribute all of our available cash each quarter, we do not otherwise have a legal obligation to distribute any particular amount per common unit.

Our intentions regarding the distribution growth profile expressed above include forward-looking statements. Such forward-looking statements are not guarantees of future performance and are subject to risks, uncertainties and other factors, some of which are beyond our control and are difficult to predict. Factors that could cause actual results to differ materially from those in the forward-looking statements include: the adequacy of our capital resources and liquidity, including, but not limited to, the availability of sufficient cash flow to pay distributions and execute our business plan; the timing and extent of changes in commodity prices and demand for crude oil, refined products, feedstocks or other hydrocarbon-based products; volatility in and/or degradation of market and industry conditions; completion of pipeline capacity by our competitors; disruptions due to equipment interruption or failure, including electrical shortages and power grid failures; the suspension, reduction or termination of MPC’s obligations under our commercial agreements; our ability to successfully implement our growth strategy, whether through organic growth or acquisitions; state and federal environmental, economic, health and safety, energy and other policies and regulations; other risk factors inherent to our industry; and the factors set forth under the heading “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2013. In addition, the forward-looking statements included herein could be affected by general domestic and international economic and political conditions. Unpredictable or unknown factors not discussed here or in our SEC filings could also have material adverse effects on forward-looking statements.

Contractual Cash Obligations

As of September 30, 2014, our contractual cash obligations included revolving credit commitment/administrative fees and borrowings, capital and operating lease obligations, purchase obligations for services and to acquire property, plant and equipment and other liabilities. During the nine months ended September 30, 2014, our revolving credit facility committed payments increased $264.3 million due to borrowing on the Credit Agreement to purchase the additional interest in Pipe Line Holdings, including interest and fees, expense project contracts increased $8.1 million due to the timing of project work during 2014 and contracts to acquire property, plant and equipment increased $19.6 million largely due to the spend associated with a tank expansion project in Patoka, Illinois. There were no other material changes to these obligations outside the ordinary course of business since December 31, 2013.

Off-Balance Sheet Arrangements

As of September 30, 2014, we have not entered into any transactions, agreements or other arrangements that would result in off-balance sheet liabilities.

Our opinions concerning liquidity and capital resources and our ability to avail ourselves in the future of the financing options mentioned in the above forward-looking statements are based on currently available information. If this information proves to be inaccurate, future availability of financing may be adversely affected. Factors that affect the availability of financing include our performance (as measured by various factors, including cash provided by operating activities), the state of worldwide debt and equity markets, investor perceptions and expectations of past and future performance, the global financial climate, and, in particular, with respect to borrowings, the levels of our outstanding debt and future credit ratings by rating agencies. The discussion of liquidity and capital resources above also contains forward-looking statements regarding expected capital spending. The forward-looking statements about our capital budget are based on current expectations, estimates and projections and are not guarantees of future performance. Actual results may differ materially from these expectations, estimates and projections and are subject to certain risks, uncertainties and other factors, some of which are beyond our control and are difficult to predict. Some factors that could cause actual results to differ materially include prices of and demand for crude oil and refined products, actions of competitors, delays in obtaining necessary third-party approvals, changes in labor, material and equipment costs and availability, planned and unplanned outages, the delay of, cancellation of or failure to implement planned capital projects, project overruns, disruptions or interruptions of our pipeline operations due to the shortage of skilled labor and unforeseen hazards such as weather conditions, acts of war or terrorist acts and the governmental or military response, and other operating and economic considerations.

TRANSACTIONS WITH RELATED PARTIES

Following completion of the Offering, MPC held a two percent general partner interest and a 71.6 percent limited partner interest in MPLX LP.

Excluding revenues attributable to volumes shipped by MPC under joint tariffs with third parties that are treated as third-party revenues for accounting purposes, MPC accounted for 86 percent and 82 percent of our total revenues and other income for the nine months ended September 30, 2014 and 2013, respectively. We provide crude oil and product pipeline transportation services based on regulated tariff rates and storage services based on contracted rates. MPC accounted for 42 percent of our total costs and expenses for the first nine months of 2014 and 2013. We believe that transactions with related parties have been conducted under terms comparable to those with unrelated parties. For further discussion of agreements and activity with MPC and related parties see Item 1. Business in our Annual Report on Form 10-K for the year ended December 31, 2013.

Effective March 1, 2014, we acquired a 13 percent interest in Pipe Line Holdings from MPC for consideration of $310.0 million, which was funded with $40.0 million of cash on hand and by borrowing $270.0 million on our bank revolver. The terms of the acquisition were approved by the conflicts committee of the board of directors of our general partner, which is comprised entirely of independent directors.

On March 31, 2014, Pipe Line Holdings entered into a credit agreement with MPL Investment LLC, a subsidiary of MPC, providing for a $50.0 million revolving credit facility which is scheduled to terminate on March 31, 2019. The agreement requires that we remain in compliance with the covenants, terms and conditions to which we are subject under the Credit Agreement. Borrowings of revolving loans under this credit facility bear interest at the one-month term LIBO Rate plus 1.375 percent. As of September 30, 2014, there were no borrowings outstanding under this facility.

ENVIRONMENTAL MATTERS AND COMPLIANCE COSTS

We have incurred and may continue to incur substantial capital, operating and maintenance, and remediation expenditures as a result of environmental laws and regulations. If these expenditures, as with all costs, are not ultimately reflected in the prices of our products and services, our operating results will be adversely affected. We believe that substantially all of our competitors must comply with similar environmental laws and regulations. However, the specific impact on each competitor may vary depending on a number of factors, including, but not limited to, the age and location of its operating facilities.

As of September 30, 2014, there have been no significant changes to our environmental matters and compliance costs since our Annual Report on Form 10-K for the year ended December 31, 2013 was filed.

CRITICAL ACCOUNTING ESTIMATES

As of September 30, 2014, there have been no significant changes to our critical accounting estimates since our Annual Report on Form 10-K for the year ended December 31, 2013 was filed.

ACCOUNTING STANDARDS NOT YET ADOPTED

In August 2014, the FASB issued an accounting standards update requiring management to assess an entity's ability to continue as a going concern and to provide related footnote disclosures in certain circumstances. Management will be required to assess if there is substantial doubt about an entity's ability to continue as a going concern within one year after the date that the financial statements are issued. Disclosures will be required if conditions give rise to substantial doubt and the type of disclosure will be determined based on whether management's plans will be able to alleviate the substantial doubt. The accounting standards update will be effective for the first annual period ending after December 15, 2016, and for annual periods and interim periods thereafter with early application permitted.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Market risk is the risk of loss arising from adverse changes in market rates and prices. As we do not take ownership of the crude oil or products that we transport and store for our customers, and we do not engage in the trading of any commodities, we have minimal direct exposure to risks associated with fluctuating commodity prices. In addition, our transportation and storage services agreements with MPC are indexed to inflation to mitigate our exposure to increases in the cost of supplies used in our business.

Sensitivity analysis of the effect of a hypothetical 100-basis-point change in interest rates on long-term debt, excluding capital leases, is provided in the following table. Fair value of cash and cash equivalents, receivables, accounts payable and accrued interest approximate carrying value and are relatively insensitive to changes in interest rates due to the short-term maturity of the instruments. Accordingly, these instruments are excluded from the table.



(In millions)	Fair Value as of September 30, 2014⁽¹⁾		Change in Net Income for the Nine Months Ended September 30, 2014 ⁽²⁾
Long-term debt	$	255.3	$	1.5


⁽¹⁾	Fair value of the variable-rate debt approximates carrying value.


⁽²⁾	Assumes a 100-basis-point change in interest rates. The change to net income was based on the weighted average balance of debt outstanding for the nine months ended September 30, 2014.

At September 30, 2014, our portfolio of long-term debt consisted of variable-rate borrowings under our bank revolving credit agreement. Interest rate fluctuations generally do not impact the fair value of borrowings under our bank revolving credit agreement, but may affect our results of operations and cash flows. As of September 30, 2014, we did not have any financial derivative instruments to hedge the risks related to interest rate fluctuations; however, we continually monitor the market and our exposure and may enter into these agreements in the future.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

An evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13(a)-15(e) and 15(d)-15(e) under the Securities Exchange Act of 1934, as amended) was carried out under the supervision and with the participation of management, including the chief executive officer and chief financial officer of our general partner. Based upon that evaluation, the chief executive officer and chief financial officer of our general partner concluded that the design and operation of these disclosure controls and procedures were effective as of September 30, 2014, the end of the period covered by this report.

Internal Control Over Financial Reporting and Changes in Internal Control Over Financial Reporting

During the quarter ended September 30, 2014, there were no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Part II – Other Information

Item 1. Legal Proceedings

Litigation

We are a party to a number of lawsuits and other proceedings and cannot predict the outcome of every such matter with certainty. While it is possible that an adverse result in one or more of the lawsuits or proceedings in which we are a defendant could be material to us, based upon current information and our experience as a defendant in other matters, we believe that these lawsuits and proceedings, individually or in the aggregate, will not have a material adverse effect on our consolidated results of operations, financial position or cash flows.

Environmental Proceedings

We are involved in a number of environmental proceedings arising in the ordinary course of business. While the ultimate outcome and impact on us cannot be predicted with certainty, we believe the resolution of these environmental proceedings will not have a material adverse effect on our consolidated results of operations, financial position or cash flows.

Item 1A. Risk Factors

We are subject to various risks and uncertainties in the course of our business. The discussion of such risks and uncertainties may be found under Item 1A. Risk Factors in our Annual Report on Form 10-K for the year ended December 31, 2013.
