Table of Contents

Notes to Consolidated Financial Statements (Unaudited)
1. Description of the Business and Basis of Presentation
Description of the Business—As used in this report, the terms “MPC,” “we,” “us,” “the Company” or “our” may refer to Marathon Petroleum Corporation, one or more of its consolidated subsidiaries or all of them taken as a whole.
Our business consists of refining and marketing, retail marketing and pipeline transportation operations conducted primarily in the Midwest, Gulf Coast and Southeast regions of the United States, through subsidiaries, including Marathon Petroleum Company LP, Speedway LLC and MPLX LP and its subsidiaries (“MPLX”).
See Note 9 for additional information about our operations.
Basis of Presentation—All significant intercompany transactions and accounts have been eliminated.
These 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 of the Securities and Exchange Commission applicable to interim period financial statements and do not include all of the information and disclosures required by United States generally accepted accounting principles (“US 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, 2012. The results of operations for the three and nine months ended September 30, 2013 are not necessarily indicative of the results to be expected for the full year.
In the fourth quarter of 2012, we reclassified certain expenses from selling, general and administrative expenses to cost of revenues, which is consistent with expense classifications for MPLX, MPC’s consolidated subsidiary. Historical periods were also reclassified to conform to the current period presentation. This reclassification resulted in an increase in cost of revenues and a decrease in selling, general and administrative expenses of $12 million and $35 million in the three and nine months ended September 30, 2012, respectively.
2. Accounting Standards
Recently Adopted
In February 2013, the Financial Accounting Standards Board (“FASB”) issued an accounting standards update that requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. If the amount reclassified is required under US GAAP to be reclassified to net income in its entirety in the same reporting period, an entity is required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income. For other amounts not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional detail about those amounts. The accounting standards update was to be applied prospectively for interim and annual periods beginning with the first quarter of 2013. The adoption of this accounting standards update in the first quarter of 2013 did not have an impact on our consolidated results of operations, financial position or cash flows. The new required disclosures are included in Note 19.
In July 2012, the FASB issued an accounting standards update that gives an entity the option to first assess qualitatively whether it is more likely than not that an indefinite-lived intangible asset is impaired. If, through the qualitative assessment, an entity determines that it is more likely than not that the intangible asset is impaired, the quantitative impairment test must then be performed. The accounting standards update was effective for annual and interim impairment tests performed in fiscal years beginning after September 15, 2012. Early adoption was permitted. The adoption of this accounting standards update in the first quarter of 2013 did not have an impact on our consolidated results of operations, financial position or cash flows. We perform the annual intangible asset impairment testing in the fourth quarter.
In December 2011, the FASB issued an accounting standards update which was amended in January 2013 that requires disclosure of additional information related to recognized derivative instruments, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions that are offset or are not offset but are subject to an enforceable netting agreement. The purpose of the requirement is to help users evaluate the effect or potential effect of offsetting and related netting arrangements on an entity’s financial position. The update was to be applied retrospectively and was effective for interim and annual periods beginning with the first quarter of 2013. The adoption of this

Table of Contents

accounting standards update in the first quarter of 2013 did not have an impact on our consolidated results of operations, financial position or cash flows. The new required disclosures are included in Note 15.
3. MPLX LP
MPLX is a publicly traded master limited partnership that was formed by us 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. MPLX’s initial assets consisted of a 51 percent general partner interest in MPLX Pipe Line Holdings LP (“Pipe Line Holdings”), which owns 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, and a 100 percent interest in a butane storage cavern in West Virginia. On May 1, 2013, we sold an additional five percent interest in Pipe Line Holdings to MPLX for $100 million. This increased MPLX’s ownership interest in Pipe Line Holdings to 56 percent and reduced our ownership interest to 44 percent.
On October 31, 2012, MPLX completed its initial public offering of 19,895,000 common units. Net proceeds to MPLX from the sale of the units were $407 million. We own a 73.6 percent interest in MPLX, including the two percent general partner interest. We consolidate this entity for financial reporting purposes since we have a controlling financial interest, and we record a noncontrolling interest for the interest owned by the public. The initial public offering represented the sale of a 26.4 percent interest in MPLX.
4. Acquisitions and Investments
Acquisition of Refinery and Related Logistics and Marketing Assets
On February 1, 2013, we paid $1.49 billion to acquire from BP Products North America Inc. and BP Pipelines (North America) Inc. (collectively, “BP”) the 451,000 barrel per calendar day refinery in Texas City, Texas, three intrastate natural gas liquid pipelines originating at the refinery, an allocation of BP’s Colonial Pipeline Company shipper history, four light product terminals, branded-jobber marketing contract assignments for the supply of approximately 1,200 branded sites and a 1,040 megawatt electric cogeneration facility, as well as the inventory associated with these assets. We refer to these assets as the “Galveston Bay Refinery and Related Assets”. Pursuant to the purchase and sale agreement, we may also be required to pay to BP a contingent earnout of up to an additional $700 million over six years, subject to certain conditions as discussed below. These assets complement our current geographic footprint and align with our strategic initiative of growing in existing and contiguous markets to enhance our portfolio. The transaction was funded with cash on hand.

As of the acquisition date, we recorded a contingent liability of $600 million, representing the preliminary fair value of contingent consideration we expect to pay to BP related to the earnout provision. The fair value of the contingent consideration was estimated using an income approach. The amount of cash to be paid under the arrangement is based on both a market-based crack spread and refinery throughput volumes for the months during which the contract applies, as well as established thresholds that cap the annual and total payment. The earnout payment cannot exceed $200 million per year for the first three years of the arrangement or $250 million per year for the last three years of the arrangement, with the total cumulative payment capped at $700 million over the six-year period. Any excess or shortfall from the annual cap for a current year’s earnout calculation will not affect subsequent years’ calculations. We used internal and external forecasts for the crack spread and internal forecasts for refinery throughput volumes and applied an appropriate risk-adjusted discount rate to the range of cash flows indicated by various scenarios to determine the fair value of the arrangement. The fair value of the contingent consideration is reassessed each quarter, with changes in fair value recorded in cost of revenues. The fair value of the contingent consideration was $606 million at September 30, 2013, which includes $108 million classified as current. See Note 15 for additional information.
The transaction provided for a post-closing adjustment for inventory, which was finalized for $9 million during the three months ended September 30, 2013, reducing our total consideration.
The components of the fair value of consideration transferred are as follows:

Represents a capital lease obligation assumed.
Neither goodwill nor a gain from a bargain purchase was recognized in conjunction with the Galveston Bay Refinery and Related Assets acquisition.

Other noncurrent assets consist of a $20 million intangible asset related to customer relationships and a $68 million intangible asset related to prepaid licensed refinery technology agreements. The intangible assets related to customer relationships and prepaid licensed refinery technology agreements are being amortized on a straight-line basis over four and 15 years, respectively. The weighted average life over which these acquired intangibles are being amortized is approximately 13 years.
We recognized $7 million of acquisition-related costs associated with the Galveston Bay Refinery and Related Assets acquisition. These costs were expensed and were included in selling, general and administrative expenses.
Our refineries and related assets are operated as an integrated system. As the information is not available by refinery, it is not practicable to disclose the revenues and net income associated with the acquisition that were included in our consolidated statements of income for the three and nine months ended September 30, 2013.
The following unaudited pro forma financial information presents consolidated results assuming the Galveston Bay Refinery and Related Assets acquisition occurred on January 1, 2012. The pro forma financial information does not give effect to potential synergies that could result from the acquisition and is not necessarily indicative of the results of future operations.

Acquisitions of Convenience Stores
During the nine months ended September 30, 2013, Speedway LLC acquired nine convenience stores located in Tennessee, western Indiana and western Pennsylvania. In connection with these acquisitions, our Speedway segment recorded $8 million of goodwill, which is deductible for income tax purposes.
In July 2012, Speedway LLC acquired 10 convenience stores located in the northern Kentucky and southwestern Ohio regions from Road Ranger LLC in exchange for cash and a truck stop location in the Chicago metropolitan area. In connection with this acquisition, our Speedway segment recorded $5 million of goodwill, which is deductible for income tax purposes.
In May 2012, Speedway LLC acquired 87 convenience stores situated throughout Indiana and Ohio from GasAmerica Services, Inc., along with the associated inventory, intangible assets and two parcels of undeveloped real estate. In connection with this acquisition, our Speedway segment recorded $83 million of goodwill, which is deductible for income tax purposes.
These acquisitions support our strategic initiative to increase our Speedway segment sales and profitability. The principal factors contributing to a purchase price resulting in goodwill included the acquired stores complementing our existing network in our Midwest market, access to our refined product transportation systems and the potential for higher merchandise sales.
Assuming these transactions had been made at the beginning of any period presented, the consolidated pro forma results would not be materially different from reported results.
Investments in Ethanol Companies
On August 1, 2013, we acquired from Mitsui & Co. (U.S.A.), Inc. its interests in three ethanol companies for $75 million. Under the purchase agreement, we acquired an additional 24 percent interest in The Andersons Clymers Ethanol LLC ("TACE"), bringing our ownership interest to 60 percent; a 34 percent interest in The Andersons Ethanol Investment LLC, which holds a 50 percent ownership in The Andersons Marathon Ethanol LLC ("TAME"), bringing our direct and indirect ownership interest in TAME to 67 percent; and a 40 percent interest in The Andersons Albion Ethanol LLC ("TAAE"), which owns an ethanol production facility in Albion, Michigan. We hold a noncontrolling interest in each of these entities and account for them using the equity method of accounting since the minority owners have substantive participating rights.
On October 1, 2013, our ownership interest in TAAE increased to 43 percent as a result of TAAE redeeming one of the owner's interest.
5. Related Party Transactions
Our related parties include:
TAAE, in which we have a 43 percent interest, TACE, in which we have a 60 percent noncontrolling interest and TAME, in which we have a 67 percent direct and indirect noncontrolling interest. These companies each own an ethanol production facility.
Centennial Pipeline LLC (“Centennial”), in which we have a 50 percent noncontrolling interest. Centennial owns a refined products pipeline and storage facility.
LOOP LLC (“LOOP”), in which we have a 51 percent noncontrolling interest. LOOP owns and operates the only U.S. deepwater oil port.

6. Variable Interest Entity
On December 1, 2010, we completed the sale of most of our Minnesota assets. These assets included the 74,000 barrel per calendar day St. Paul Park refinery and associated terminals, 166 convenience stores primarily branded SuperAmerica®, along with the SuperMom’s bakery and certain associated trademarks, SuperAmerica Franchising LLC, interests in pipeline assets in Minnesota and associated inventories. We refer to these assets as the “Minnesota Assets.” The terms of the sale included (1) a preferred stock interest in the entity that holds the Minnesota Assets with a stated value of $80 million, (2) a maximum $125 million earnout provision payable to us over eight years, (3) a maximum $60 million of margin support payable to the buyer over two years, up to a maximum of $30 million per year, (4) a receivable from the buyer of $107 million which was fully collected in 2011, and (5) lease guarantees made by us on behalf of and to the buyer related to a limited number of convenience store sites. As a result of this continuing involvement, the related gain on sale of $89 million was initially deferred.
In July 2012, the buyer of our Minnesota Assets successfully completed an initial public offering ("IPO"). The successful completion of this IPO triggered the provisions in our May 4, 2012 settlement agreement with the buyer. Under the settlement agreement, we were released from our obligation to pay margin support and the buyer was released from its obligation to pay us under the earnout provisions contained in the original sales agreement. Also, the buyer redeemed our $80 million preferred equity interest, paid us $12 million for dividends accrued on our preferred equity interest and paid us $40 million of cash, for total cash receipts of $132 million. In addition, the buyer issued to us a second preferred security with a stated valued of $45 million. As a result, we recognized income before income taxes of approximately $183 million during the three months ended September 30, 2012, which included $86 million of the deferred gain that was recorded when the sale transaction was originally closed.
During the three months ended September 30, 2013, the buyer redeemed the second preferred security for $49 million, which included $4 million of accrued distributions.
Certain terms of the transaction and the subsequent settlement agreement with the buyer resulted in the creation of variable interests in a variable interest entity (“VIE”) that owns the Minnesota Assets. We are not the primary beneficiary of this VIE and, therefore, do not consolidate it because we lack the power to control or direct the activities that impact the VIE’s operations and economic performance. At September 30, 2013, our variable interest in this VIE and maximum exposure to loss is limited to convenience store lease guarantees of $5 million. These guarantees do not expose us to residual returns or expected losses that are significant to the VIE.
7. Income per Common Share
We compute basic earnings per share by dividing net income attributable to MPC by the weighted average number of shares of common stock outstanding. Diluted income per share assumes exercise of stock options and stock appreciation rights, provided the effect is not anti-dilutive.
Shares related to stock-based compensation awards excluded from the diluted share calculation as their effect would be anti-dilutive are approximately one million and two million shares for the three months ended September 30, 2013 and 2012 and one million and four million shares for the nine months ended September 30, 2013 and 2012, respectively.
MPC grants certain incentive compensation awards to employees and non-employee directors that are considered to be participating securities. Due to the presence of participating securities, we have calculated our earnings per share using the two-class method.

8. Equity
On February 1, 2012, we announced that our board of directors authorized a share repurchase plan, enabling us to purchase up to $2.0 billion of MPC common stock over a two-year period. Through January 30, 2013, we had acquired $1.35 billion of shares under the initial $2.0 billion authorization. On January 30, 2013, we announced that our board of directors extended the duration of the existing $650 million repurchase authorization and approved an additional $2.0 billion share repurchase authorization, both to expire in December 2014. On September 26, 2013, we announced that our board of directors approved an additional $2.0 billion share repurchase authorization through September 2015, resulting in $6.0 billion of total share repurchase authorizations since January 1, 2012. After the effects of the accelerated share repurchase (“ASR”) programs and open market repurchases shown below, $2.31 billion of the amounts authorized by our board of directors remain available for repurchases at September 30, 2013. We may utilize various methods to effect the repurchases, which could include open market repurchases, negotiated block transactions, accelerated share repurchases or open market solicitations for shares, some of which may be effected through Rule 10b5-1 plans. The timing and amount of future repurchases, if any, will depend upon several factors, including market and business conditions, and such repurchases may be discontinued at any time.
In February 2012 and November 2012, we entered into $850 million and $500 million ASR programs, respectively, to repurchase shares of MPC common stock under the approved share repurchase plan authorized by our board of directors. The total number of shares repurchased under these ASR programs was based generally on the volume-weighted average price of our common stock during the repurchase periods. The shares repurchased under the ASR programs were accounted for as treasury stock purchase transactions, reducing the weighted average number of basic and diluted common shares outstanding by the shares repurchased, and as forward contracts indexed to our common stock. The forward contracts were accounted for as equity instruments.

The three months ended September 30, 2012 includes two million shares received under the February 2012 ASR program, which were paid for in the first quarter of 2012.
As of September 30, 2013, the total number of shares we have repurchased cumulatively through the ASR programs and open market repurchases since February 2012 was 59 million shares at an average cost per share of $62.29. The cash paid for shares repurchased was $3.69 billion. In addition, at September 30, 2013, we had agreements to acquire additional common shares for $42 million, which were settled in early October 2013.
9. Segment Information
We have three reportable segments: Refining & Marketing; Speedway; and Pipeline Transportation. Each of these segments is organized and managed based upon the nature of the products and services they offer.
Refining & Marketing – refines crude oil and other feedstocks at our refineries in the Gulf Coast and Midwest regions of the United States, purchases ethanol and refined products for resale and distributes refined products through various means, including barges, terminals and trucks that we own or operate. We sell refined products to wholesale marketing customers domestically and internationally, to buyers on the spot market, to our Speedway segment and to dealers and jobbers who operate Marathon® retail outlets;
Speedway – sells transportation fuels and convenience products in retail markets in the Midwest, primarily through Speedway® convenience stores; and
Pipeline Transportation – transports crude oil and other feedstocks to our refineries and other locations, delivers refined products to wholesale and retail market areas and includes the aggregated operations of MPLX and MPC’s retained pipeline assets and investments.

On February 1, 2013, we acquired the Galveston Bay Refinery and Related Assets, which are part of the Refining & Marketing and Pipeline Transportation segments. Segment information for periods prior to the acquisition does not include amounts for these operations. See Note 4.
Segment income represents income from operations attributable to the reportable segments. Corporate administrative expenses and costs related to certain non-operating assets are not allocated to the reportable segments. In addition, certain items that affect comparability (as determined by the chief operating decision maker) are not allocated to the reportable segments.

11. Income Taxes
The combined federal, state and foreign income tax rate was 32 percent and 35 percent for the three months ended September 30, 2013 and 2012, respectively, and 34 percent and 36 percent for the nine months ended September 30, 2013 and 2012, respectively. The effective tax rate for the three and nine months ended September 30, 2013 is less than the U.S. statutory rate of 35 percent primarily due to certain permanent benefit differences, including the domestic manufacturing deduction, partially offset by state and local tax expense. The effective tax rate for the three and nine months ended September 30, 2012 exceeded the U.S. statutory rate of 35 percent due to state and local tax expense, partially offset by permanent benefit differences, including the domestic manufacturing deduction.
Prior to the June 30, 2011 spinoff transaction from Marathon Oil Corporation (“Marathon Oil”), we were included in Marathon Oil’s income tax returns for all applicable years. During 2011, we anticipated a future settlement between Marathon Oil and us upon the filing of Marathon Oil’s consolidated U.S. federal and state income tax returns for the period prior to June 30, 2011. During the second quarter of 2013, we settled with Marathon Oil for the 2011 period based on filed tax returns, resulting in a $39 million increase to additional paid-in capital.
We are continuously undergoing examination of our income tax returns, which have been completed for our U.S. federal and state income tax returns through the 2009 and 2003 tax years, respectively. We had $25 million of unrecognized tax benefits as of September 30, 2013. Pursuant to our tax sharing agreement with Marathon Oil, the unrecognized tax benefits related to pre-spinoff operations for which Marathon Oil was the taxpayer remain the responsibility of Marathon Oil and we have indemnified Marathon Oil accordingly. See Note 22 for indemnification information. During the second quarter of 2013, we settled with Marathon Oil our U.S. federal and related state return liabilities for the 2008-2009 tax years, resulting in a reduction in unrecognized tax benefits of $21 million.

(a) 
Represents the impact of netting assets, liabilities and cash collateral when a legal right of offset exists. As of December 31, 2012, cash collateral of $39 million was netted with mark-to-market derivative liabilities.
(b) 
We have no derivative contracts that are subject to master netting arrangements that are reflected gross on the balance sheet.
(c) 
Includes $108 million classified as current.
Commodity derivatives in Level 1 are exchange-traded contracts for crude oil and refined products measured at fair value with a market approach using the close-of-day settlement prices for the market. Commodity derivatives are covered under master netting agreements with an unconditional right to offset. Collateral deposits in futures commission merchant accounts covered by master netting agreements related to Level 1 commodity derivatives are classified as Level 1 in the fair value hierarchy.
The contingent consideration represents the fair value as of September 30, 2013 of the amount we expect to pay to BP related to the earnout provision for the Galveston Bay Refinery and Related Assets acquisition. See Note 4. The fair value of the contingent consideration was estimated using an income approach and is therefore a Level 3 liability. The amount of cash to be paid under the arrangement is based on both a market-based crack spread and refinery throughput volumes for the months during which the contract applies, as well as established thresholds that cap the annual and total payment. The earnout payment cannot exceed $200 million per year for the first three years of the arrangement or $250 million per year for the last three years of the arrangement, with the total cumulative payment capped at $700 million over the six-year period. Any excess or shortfall from the annual cap for a current year’s earnout calculation will not affect subsequent years’ calculations. The fair value calculation used significant unobservable inputs, including (1) an estimate of refinery throughput volumes; (2) a range of internal and external crack spread forecasts from $12 to $18 per barrel; and (3) a range of risk-adjusted discount rates from 5 percent to 10 percent. An increase or decrease in crack spread forecasts or refinery throughput volume expectations will result in a corresponding increase or decrease in the fair value. Increases to the fair value as a result of increasing forecasts for both of these unobservable inputs, however, are limited as the earnout payment is subject to annual thresholds. An increase or decrease in the discount rate will result in a decrease or increase to the fair value, respectively. The fair value of the contingent consideration is reassessed each quarter, with changes in fair value recorded in cost of revenues.
The following is a reconciliation of the beginning and ending balances recorded for liabilities classified as Level 3 in the fair value hierarchy.

See Note 16 for the income statement impacts of our derivative instruments. There was an unrealized gain of $5 million and an unrealized loss of $6 million related to the contingent consideration agreement for the three and nine months ended September 30, 2013, respectively.

Due to changing market conditions, we assessed one of our light products terminals for impairment. The terminal is operated by our Refining & Marketing segment. During the second quarter of 2013, we recorded an impairment charge of $8 million for this terminal. The impairment is included in depreciation and amortization on the consolidated statements of income. The fair value of the terminal was measured using a market approach based on comparable area property values which are Level 3 inputs.
As a result of changing market conditions and declining throughput volumes, we impaired our Refining & Marketing segment’s prepaid tariff with Centennial by $14 million during the first quarter of 2012. The fair value measurement of the prepaid tariff was based on the income approach utilizing the probability of shipping sufficient volumes on Centennial’s pipeline over the remaining life of the throughput and deficiency credits, which expire March 31, 2014 if not utilized. This measurement is classified as Level 3.

Excludes capital leases
Our current assets and liabilities include financial instruments, the most significant of which are trade accounts receivable 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) our 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 values of our financial assets included in investments and other financial assets and of our financial liabilities included in deferred credits and other liabilities are measured primarily using an income approach and most inputs are internally generated, which results in a Level 3 classification. Estimated future cash flows are discounted using a rate deemed appropriate to obtain the fair value. Other financial assets primarily consist of environmental remediation receivables. Deferred credits and other liabilities primarily consist of insurance liabilities and environmental remediation liabilities.
Fair value of long-term debt is measured using a market approach, based upon the average of quotes from major financial institutions and a third-party service for our debt. Because these quotes cannot be independently verified to the market, they are considered Level 3 inputs.

Derivatives Designated as Fair Value Accounting Hedges
During the first quarter of 2012, we terminated interest rate swap agreements with a notional amount of $500 million that had been entered into as fair value accounting hedges on our 3.50 percent senior notes due in March 2016. There was a $20 million gain on the termination of the transactions, which has been accounted for as an adjustment to our long-term debt balance. The gain is being amortized over the remaining life of the 3.50 percent senior notes, which reduces our interest expense. The interest rate swaps had no accounting hedge ineffectiveness.

Derivatives not Designated as Accounting Hedges
Derivatives that are not designated as accounting hedges may include commodity derivatives used to hedge price risk on (1) inventories, (2) fixed price sales of refined products, (3) the acquisition of foreign-sourced crude oil and (4) the acquisition of ethanol for blending with refined products.

During the nine months ended September 30, 2013, we made contributions of $158 million to our funded pension plans. We may make additional contributions to our pension plans in 2013 depending upon the anticipated funding status and plan asset performance. Current benefit payments related to unfunded pension and other postretirement benefit plans were $8 million and $14 million, respectively, during the nine months ended September 30, 2013.
Due to the Galveston Bay Refinery and Related Assets acquisition, during the first quarter of 2013, we remeasured certain pension and retiree medical plans resulting in a $122 million decrease in liabilities. The decrease in liabilities was due to a 0.2 percent increase in discount rates and an increase in pension plan asset value from December 31, 2012 to the remeasurement date. The net periodic benefit costs for the nine months ended September 30, 2013 reflect these remeasurements. The purchase accounting for the Galveston Bay Refinery and Related Assets acquisition includes a $43 million liability related to retiree medical assumed at the acquisition date. See Note 4.
During the nine months ended September 30, 2013 and 2012, we determined that lump sum payments to employees retiring in the respective year would exceed the plans’ total service and interest costs for the year. Settlement losses are required to be recorded when lump sum payments exceed total service and interest costs. As a result, during the nine months ended September 30, 2013 and 2012, we recorded pension settlement expenses related to our cumulative lump sum payments made during the first nine months of 2013 and 2012, respectively.
On May 17, 2012, we communicated to our employees changes in the defined benefit pension plans for Speedway and the legacy portion of the Marathon Petroleum Retirement Plan effective January 1, 2013. Final average pensionable earnings used to calculate pension benefits under these plans were fixed as of December 31, 2012. In addition, cap protection was added to limit potential annual lump sum distribution discount rate increases. These plan amendments resulted in an overall decrease in pension liabilities of approximately $537 million, with the offset primarily to other comprehensive income, which was recorded in the second quarter of 2012. The benefit of this liability reduction is being amortized into income through 2024.
On August 20, 2012, we communicated, to our impacted Medicare eligible retirees, changes in the post-65 medical plan coverage of the Marathon Petroleum Health Plan and the Marathon Petroleum Retiree Health Plan. Effective January 1, 2013, these Medicare eligible participants now receive a tax free contribution to a health reimbursement account, which replaces benefits provided under the previous plans. Increases are capped at 4 percent per year. This plan change resulted in a reduction in retiree medical liabilities of $40 million. This was more than offset by an increase in retiree medical liabilities of approximately $57 million primarily due to a reduction in discount rates as of the remeasurement date. The overall net liability increase and the offset to other comprehensive income was recorded during the three months ended September 30, 2012.

22. 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 loss because the issues involved have not been fully developed through pleadings and discovery. 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, local and foreign 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 and certain other locations including presently or formerly owned or operated retail marketing sites. Penalties may be imposed for noncompliance.
At September 30, 2013 and December 31, 2012, accrued liabilities for remediation totaled $127 million and $123 million, respectively. It is not presently possible to estimate the ultimate amount of all remediation costs that might be incurred or the penalties if any that may be imposed. Receivables for recoverable costs from certain states, under programs to assist companies in clean-up efforts related to underground storage tanks at presently or formerly owned or operated retail marketing sites, were $49 million and $51 million at September 30, 2013 and December 31, 2012, respectively.

Table of Contents

We are involved in a number of environmental enforcement matters arising in the ordinary course of business. While the outcome and impact on us cannot be predicted with certainty, management believes the resolution of these environmental matters will not, individually or collectively, have a material adverse effect on our consolidated results of operations, financial position or cash flows.
Lawsuits—In May 2007, the Kentucky attorney general filed a lawsuit against us and Marathon Oil in state court in Franklin County, Kentucky for alleged violations of Kentucky’s emergency pricing and consumer protection laws following Hurricanes Katrina and Rita in 2005. The lawsuit alleges that we overcharged customers by $89 million during September and October 2005. The complaint seeks disgorgement of these sums, as well as penalties, under Kentucky’s emergency pricing and consumer protection laws. We are vigorously defending this litigation. We believe that this is the first lawsuit for damages and injunctive relief under the Kentucky emergency pricing laws to progress this far and it contains many novel issues. In May 2011, the Kentucky attorney general amended his complaint to include a request for immediate injunctive relief as well as unspecified damages and penalties related to our wholesale gasoline pricing in April and May 2011 under statewide price controls that were activated by the Kentucky governor on April 26, 2011 and which have since expired. The court denied the attorney general’s request for immediate injunctive relief, and the remainder of the 2011 claims likely will be resolved along with those dating from 2005. If the lawsuit is resolved unfavorably in its entirety, it could materially impact our consolidated results of operations, financial position or cash flows. However, management does not believe the ultimate resolution of this litigation will have a material adverse effect.
We are a defendant in a number of other lawsuits and other proceedings arising in the ordinary course of business. While the ultimate outcome and impact to us cannot be predicted with certainty, we believe that the resolution of these other lawsuits and proceedings will not have a material adverse effect on our consolidated financial position, results of operations or cash flows.
Guarantees—We have provided certain guarantees, direct and indirect, of the indebtedness of other companies. Under the terms of most of these guarantee arrangements, we would be required to perform should the guaranteed party fail to fulfill its obligations under the specified arrangements. In addition to these financial guarantees, we also have various performance guarantees related to specific agreements.
Guarantees related to indebtedness of equity method investees—We hold interests in an offshore oil port, LOOP, and a crude oil pipeline system, LOCAP LLC. Both LOOP and LOCAP LLC have secured various project financings with throughput and deficiency agreements. Under the agreements, we are required to advance funds if the investees are unable to service their debt. Any such advances are considered prepayments of future transportation charges. The duration of the agreements vary but tend to follow the terms of the underlying debt, which extend through 2037. Our maximum potential undiscounted payments under these agreements for the debt principal totaled $172 million as of September 30, 2013.
We hold an interest in a refined products pipeline through our investment in Centennial, and have guaranteed the payment of Centennial’s principal, interest and prepayment costs, if applicable, under a Master Shelf Agreement, which is scheduled to expire in 2024. The guarantee arose in order for Centennial to obtain adequate financing. Our maximum potential undiscounted payments under this agreement for debt principal totaled $43 million as of September 30, 2013.
We hold an interest in an ethanol production facility through our investment in TAME, and through our participation as a lender under TAME’s revolving credit agreement, have agreed to reimburse the bank for 50 percent of any amounts drawn on a letter of credit that has been issued to secure TAME’s repayment of the tax exempt bonds. The credit agreement expires in 2018. Our maximum potential undiscounted payments under this arrangement were $25 million at September 30, 2013.
Marathon Oil indemnifications—In conjunction with our spinoff from Marathon Oil, we have entered into arrangements with Marathon Oil providing indemnities and guarantees with recorded values of $2 million as of September 30, 2013, which consist of unrecognized tax benefits related to MPC, its consolidated subsidiaries and the refining, marketing and transportation business operations prior to our spinoff which are not already reflected in the unrecognized tax benefits described in Note 11, and other contingent liabilities Marathon Oil may incur related to taxes. Furthermore, the separation and distribution agreement and other agreements with Marathon Oil to effect our spinoff provide for cross-indemnities between Marathon Oil and us. In general, Marathon Oil is required to indemnify us for any liabilities relating to Marathon Oil’s historical oil and gas exploration and production operations, oil sands mining operations and integrated gas operations, and we are required to indemnify Marathon Oil for any liabilities relating to Marathon Oil’s historical refining, marketing and transportation operations. The terms of these indemnifications are indefinite and the amounts are not capped.


28

Table of Contents

Other guarantees—We have entered into other guarantees with maximum potential undiscounted payments totaling $132 million as of September 30, 2013, which primarily consist of a commitment to contribute cash to an equity method investee for certain catastrophic events, up to $50 million per event, in lieu of procuring insurance coverage, an indemnity to the co-lenders associated with an equity method investee’s credit agreement, and leases of assets containing general lease indemnities and guaranteed residual values.
General guarantees associated with dispositions – 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, 2013, our contractual commitments to acquire property, plant and equipment and advance funds to equity method investees totaled $876 million, which includes $700 million of contingent consideration associated with the acquisition of the Galveston Bay Refinery and Related Assets. See Note 4 for additional information on the contingent consideration.

Corporate Overview
We are an independent petroleum refining, marketing and transportation company. We currently own and operate seven refineries, all located in the United States, with an aggregate crude oil refining capacity of approximately 1.7 million barrels per calendar day. Our refineries supply refined products to resellers and consumers within our market areas, including the Midwest, Gulf Coast and Southeast regions of the United States. We distribute refined products to our customers through one of the largest private domestic fleets of inland petroleum product barges, one of the largest terminal operations in the United States, and a combination of MPC-owned and third-party-owned trucking and rail assets. We currently own, lease or have ownership interests in approximately 8,300 miles of crude oil and refined product pipelines to deliver crude oil to our refineries and other locations and refined products to wholesale and retail market areas. We are one of the largest petroleum pipeline companies in the United States on the basis of total volumes delivered.
Our operations consist of three reportable segments: Refining & Marketing; Speedway; and Pipeline Transportation. Each of these segments is organized and managed based upon the nature of the products and services they offer.
Refining & Marketing—refines crude oil and other feedstocks at our seven refineries in the Gulf Coast and Midwest regions of the United States, purchases ethanol and refined products for resale and distributes refined products through various means, including barges, terminals and trucks that we own or operate. We sell refined products to wholesale marketing customers domestically and internationally, to buyers on the spot market, to our Speedway business segment and to dealers and jobbers who operate Marathon® retail outlets;
Speedway—sells transportation fuels and convenience products in the retail market in the Midwest, primarily through Speedway® convenience stores; and
Pipeline Transportation—transports crude oil and other feedstocks to our refineries and other locations, delivers refined products to wholesale and retail market areas and includes the aggregated operations of MPLX and MPC’s retained pipeline assets and investments.
Executive Summary
Net income attributable to MPC was $168 million and $1.49 billion, or $0.54 and $4.60 per diluted share, for the third quarter and first nine months of 2013 compared to $1.22 billion and $2.63 billion, or $3.59 and $7.65 per diluted share, for the third quarter and first nine months of 2012. The decreases were primarily due to our Refining & Marketing segment, which generated income from operations of $227 million and $2.24 billion in the third quarter and first nine months of 2013 compared to $1.69 billion and $3.96 billion in the third quarter and first nine months of 2012.
The decreases in Refining & Marketing segment income from operations were primarily due to decreases in refining and marketing gross margins, which were $2.55 per barrel and $5.42 per barrel in the third quarter and first nine months of 2013 compared to $13.12 per barrel and $10.92 per barrel in the third quarter and first nine months of 2012. These impacts were partially offset by increases in refinery throughputs and refined product sales volumes related to the Galveston Bay refinery acquired in February 2013.
Speedway segment income from operations increased $26 million in the third quarter and $59 million in the first nine months of 2013 compared to the third quarter and first nine months of 2012, primarily due to increases in our gasoline and distillate gross margin and our merchandise gross margin, partially offset by less income due to the absence of asset sales and higher operating expenses.

Table of Contents

Pipeline Transportation segment income from operations increased $2 million in the third quarter and $19 million in the first nine months of 2013 compared to the third quarter and first nine months of 2012. The increases primarily reflect higher transportation tariffs, partially offset by higher operating and depreciation expenses.
On February 1, 2013, we paid $1.49 billion to acquire from BP the 451,000 barrel per calendar day refinery in Texas City, Texas, three intrastate natural gas liquid pipelines originating at the refinery, an allocation of BP’s Colonial Pipeline Company shipper history, four light product terminals, branded-jobber marketing contract assignments for the supply of approximately 1,200 branded sites and a 1,040 megawatt electric cogeneration facility, as well as the inventory associated with these assets. We refer to these assets as the “Galveston Bay Refinery and Related Assets”. Pursuant to the purchase and sale agreement, we may also be required to pay BP a contingent earnout of up to an additional $700 million over six years, subject to certain conditions. These assets are part of our Refining & Marketing and Pipeline Transportation segments. Information for periods prior to the acquisition does not include amounts for these operations. See Note 4 to the unaudited consolidated financial statements for additional information on this acquisition.
On August 1, 2013, we acquired from Mitsui & Co. (U.S.A.), Inc. its interests in three ethanol companies for $75 million. Under the purchase agreement, we acquired an additional 24 percent interest in TACE, bringing our ownership interest to 60 percent; a 34 percent interest in The Andersons Ethanol Investment LLC, which holds a 50 percent ownership in TAME, bringing our direct and indirect ownership interest in TAME to 67 percent; and a 40 percent interest in TAAE, which owns an ethanol production facility in Albion, Michigan. We hold a noncontrolling interest in each of these entities and account for them using the equity method of accounting since the minority owners have substantive participating rights.
On January 30, 2013, we announced that our board of directors approved an additional $2.0 billion share repurchase authorization. The board also extended the remaining $650 million share repurchase authorization for a total outstanding authorization of $2.65 billion through December 2014. On September 26, 2013, we announced that our board of directors approved an additional $2.0 billion share repurchase authorization through September 2015. During the first nine months of 2013, the final shares from the $500 million ASR program were delivered to us and we paid $2.34 billion to acquire 30 million common shares through open market share repurchases. The effective average cost was $76.01 per delivered share. At September 30, 2013, we also had agreements to repurchase additional common shares for $42 million, which were settled in early October 2013. As of September 30, 2013, we had total outstanding repurchase authorizations pursuant to the authorizations announced on January 30, 2013 and September 26, 2013 of approximately $2.31 billion.
Overview of Segments
Refining & Marketing
Refining & Marketing segment income from operations depends largely on our refining and marketing gross margin and refinery throughputs.
Our refining and marketing gross margin is the difference between the prices of refined products sold and the costs of crude oil and other charge and blendstocks refined, including the costs to transport these inputs to our refineries, the costs of purchased products and refinery direct operating costs, including turnaround and major maintenance, depreciation and amortization and other manufacturing expenses. The crack spread is a measure of the difference between market prices for refined products and crude oil, commonly used by the industry as a proxy for the refining margin. Crack spreads can fluctuate significantly, particularly when prices of refined products do not move in the same relationship as the cost of crude oil. As a performance benchmark and a comparison with other industry participants, we calculate Midwest (Chicago) and U.S. Gulf Coast (“USGC”) crack spreads that we believe most closely track our operations and slate of products. Light Louisiana Sweet crude oil (“LLS”) prices and a 6-3-2-1 ratio of products (6 barrels of LLS crude oil producing 3 barrels of unleaded regular gasoline, 2 barrels of ultra-low sulfur diesel and 1 barrel of 3 percent sulfur residual fuel) are used for these crack-spread calculations.
Our refineries can process significant amounts of sour crude oil, which typically can be purchased at a discount to sweet crude oil. The amount of this discount, the sweet/sour differential, can vary significantly, causing our refining and marketing gross margin to differ from crack spreads based on sweet crude oil. In general, a larger sweet/sour differential will enhance our refining and marketing gross margin.
Historically, West Texas Intermediate crude oil (“WTI”) has traded at prices similar to LLS. During the first nine months of 2012 and in early 2013, WTI traded at prices significantly less than LLS, which favorably impacted our refining and marketing gross margin. Logistical constraints in the U.S. mid-continent markets and other market factors acted to keep the price of WTI from rising with the prices of crude oil produced in other regions. However, the differential between WTI and LLS significantly narrowed in the second and third quarters of 2013 due to a variety of domestic and international market conditions along with changes in logistical infrastructure. Future crude oil differentials will be dependent on a variety of market and economic factors.

Assumes 20% of crude oil throughput volumes are WTI-based domestic crude oil.
In addition to the market changes indicated by the crack spreads, the sweet/sour differential and the discount of WTI to LLS, our refining and marketing gross margin is impacted by factors such as:
the types of crude oil and other charge and blendstocks processed;
the selling prices realized for refined products;
the impact of commodity derivative instruments used to hedge price risk;
the cost of products purchased for resale; and
changes in refinery direct operating costs, which include turnaround and major maintenance, depreciation and amortization and other manufacturing expenses.
Changes in manufacturing costs are primarily driven by the cost of energy used by our refineries, including purchased natural gas, and the level of maintenance costs. Planned major maintenance activities, or turnarounds, requiring temporary shutdown of certain refinery operating units, are periodically performed at each refinery. We had significant planned turnaround and major maintenance activities at our Catlettsburg, Kentucky; Garyville, Louisiana; and Galveston Bay refineries during the first nine months of 2013 compared to activities at our Detroit, Michigan; Garyville; and Robinson, Illinois refineries during the first nine months of 2012.
Speedway
Our retail marketing gross margin for gasoline and distillate, which is the price paid by consumers less the cost of refined products, including transportation, consumer excise taxes and bankcard processing fees, impacts the Speedway segment profitability. Numerous factors impact gasoline and distillate demand throughout the year, including local competition, seasonal demand fluctuations, the available wholesale supply, the level of economic activity in our marketing areas and weather conditions. Market demand increases for gasoline and distillate generally increase the product margin we can realize. The gross margin on merchandise sold at convenience stores historically has been less volatile. Approximately two-thirds of Speedway’s gross margin was derived from merchandise sales in the third quarter and first nine months of 2013.

Pipeline Transportation
The profitability of our pipeline transportation operations primarily depends on tariff rates and the volumes shipped through the pipelines. A majority of the crude oil and refined product shipments on our common carrier pipelines serve our Refining & Marketing segment. In the fourth quarter of 2012, new transportation services agreements were entered into between MPC and MPLX, which resulted in higher tariff rates. The volume of crude oil that we transport is directly affected by the supply of, and refiner demand for, crude oil in the markets served directly by our crude oil pipelines. Key factors in this supply and demand balance are the production levels of crude oil by producers in various regions or fields, the availability and cost of alternative modes of transportation, the volumes of crude oil processed at refineries and refinery and transportation system maintenance levels. The volume of refined products that we transport is directly affected by the production levels of, and user demand for, refined products in the markets served by our refined product pipelines. In most of our markets, demand for gasoline and distillates peaks during the summer driving season, which extends from May through September of each year, and declines during the fall and winter months. As with crude oil, other transportation alternatives and system maintenance levels influence refined product movements.

Net income attributable to MPC decreased $1.06 billion in the third quarter and $1.15 billion in the first nine months of 2013 compared to the third quarter and first nine months of 2012, primarily due to decreases in refining and marketing gross margins, which were $2.55 per barrel and $5.42 per barrel in the third quarter and first nine months of 2013 compared to $13.12 per barrel and $10.92 per barrel in the third quarter and first nine months of 2012. These impacts were partially offset by increases in refinery throughputs and refined product sales volumes related to the Galveston Bay refinery acquired in February 2013.
Sales and other operating revenues (including consumer excise taxes) increased $5.21 billion in the third quarter and $13.71 billion in the first nine months of 2013 compared to the third quarter and first nine months of 2012, primarily due to higher refined product sales volumes, which increased to 2,155 thousand barrels per day (“mbpd”) and 2,063 mbpd in the third quarter and first nine months of 2013 from 1,622 mbpd and 1,590 mbpd in the third quarter and first nine months of 2012, primarily due to the Galveston Bay refinery acquired in February 2013. This impact was partially offset by decreases in refined product selling prices.
Net gain on disposal of assets decreased $174 million in the third quarter and $175 million in the first nine months of 2013 compared to the third quarter and first nine months of 2012, primarily due to the absence of a $171 million gain recognized in the third quarter of 2012 associated with the settlement agreement with the buyer of our Minnesota Assets.
Other income decreased $10 million in the third quarter and increased $12 million in the first nine months of 2013 compared to the third quarter and first nine months of 2012. The decrease in the third quarter was primarily due to the absence of $12 million of dividends received from our preferred equity interest in the buyer of our Minnesota Assets in connection with the

Table of Contents

settlement agreement with the buyer in the third quarter of 2012, partially offset by an increase in dividends received from a pipeline affiliate in third quarter of 2013. The increase in the first nine months was primarily due to increases in sales of Renewable Identification Numbers (“RINs”) and dividends received from a pipeline affiliate, partially offset by the absence of $12 million of dividends received from our preferred equity interest in the buyer of our Minnesota Assets during the third quarter of 2012. See Note 6 to the unaudited consolidated financial statements for additional information on the Minnesota Assets sale and subsequent settlement agreement with the buyer.
Cost of revenues increased $6.35 billion in the third quarter and $14.58 billion in the first nine months of 2013 compared to the third quarter and first nine months of 2012. The increases were primarily due to increases in purchased crude oil volumes in the Refining & Marketing segment. Crude oil volumes increased 42 percent in the third quarter and 35 percent in the first nine months of 2013 compared to the third quarter and first nine months of 2012, primarily associated with the Galveston Bay refinery acquired in February 2013. The third quarter of 2013 was also impacted by higher acquisition costs per barrel of crude oil compared to the third quarter of 2012.
Purchases from related parties increased $19 million in the third quarter and $50 million in the first nine months of 2013 compared to the third quarter and first nine months of 2012, primarily due to increases in ethanol volumes purchased from our ethanol investments, including purchases from TAAE, which became an equity method affiliate on August 1, 2013. Our acquisition costs of ethanol from our ethanol investments was also impacted by lower ethanol prices in the third quarter of 2013 and higher ethanol prices in the first nine months of 2013. In addition, purchases from Centennial increased during the third quarter but decreased for the first nine months of 2013 compared to 2012.
Centennial experienced a significant reduction in shipment volumes in the second half of 2011 that continued through the first nine months of 2013. At September 30, 2013, Centennial was not shipping product. As a result, we continued to evaluate the carrying value of our equity investment in Centennial and concluded that no impairment was required given our assessment of its fair value based on various potential uses of Centennial’s assets. If current business conditions remain unchanged and the owners of Centennial are unable to find an alternative use for the assets, there could be a future impairment of our Centennial interest. As of September 30, 2013, our equity investment in Centennial was $30 million and we had a $43 million guarantee associated with 50 percent of Centennial's outstanding debt. See Note 22 to our unaudited consolidated financial statements for additional information on the debt guarantee.
Consumer excise taxes increased $168 million in the third quarter and $414 million in the first nine months of 2013 compared to the same periods of 2012, primarily due to increases in refined product sales volumes related to the Galveston Bay refinery acquired in February 2013.
Depreciation and amortization increased $53 million in the third quarter and $176 million in the first nine months of 2013 compared to the third quarter and first nine months of 2012, primarily due to the completion of the heavy oil upgrading and expansion project at our Detroit, Michigan refinery and our acquisition of the Galveston Bay Refinery and Related Assets.
Other taxes increased $16 million in the third quarter and $55 million in the first nine months of 2013 compared to the third quarter and first nine months of 2012, primarily due to increases in personal property and payroll taxes. These increases were attributable to a number of factors including the completion of the heavy oil upgrading and expansion project at our Detroit refinery, the acquisition of the Galveston Bay Refinery and Related Assets and Speedway’s acquisition of 97 convenience stores in 2012. The increase in the third quarter was also partially due to an increase in sales and use tax expense primarily attributable to the acquisition of the Galveston Bay Refinery and Related Assets.
Net interest and other financial costs increased $22 million in the third quarter and $76 million in the first nine months of 2013 compared to the third quarter and first nine months of 2012, primarily reflecting decreases in capitalized interest due to the completion of the Detroit refinery heavy oil upgrading and expansion project in late 2012. We capitalized interest of $7 million in the third quarter and $15 million in the first nine months of 2013 compared to $29 million in the third quarter and $95 million in the first nine months of 2012.
Provision for income taxes decreased $565 million in the third quarter and $685 million in the first nine months of 2013 compared to the third quarter and first nine months of 2012, primarily due to the $1.62 billion and $1.82 billion decreases in income before income taxes. The effective tax rates were 32 percent and 34 percent in the third quarter and first nine months of 2013 compared to 35 percent and 36 percent in the same periods of 2012. The effective tax rate in the third quarter and first nine months of 2013 is less than the U.S. statutory rate of 35 percent primarily due to certain permanent benefit differences, including the domestic manufacturing deduction, partially offset by state and local tax expense. See Note 11 to the unaudited consolidated financial statements for further details.

Refining & Marketing intersegment sales to our Speedway segment were $2.44 billion in the third quarter and $7.07 billion in the first nine months of 2013 compared to $2.39 billion in the third quarter and $6.56 billion in the first nine months of 2012. Intersegment refined product sales volumes were 774 million gallons in the third quarter and 2.21 billion gallons in the first nine months of 2013 compared to 714 million gallons in the third quarter and 2.00 billion gallons in the first nine months of 2012, with the increased volumes in the first nine months of 2013 partially due to Speedway’s acquisitions of convenience stores in 2013 and 2012.
Speedway segment revenues decreased $32 million in the third quarter and increased $261 million in the first nine months of 2013 compared to the third quarter and first nine months of 2012. The $32 million decrease in the third quarter of 2013 was primarily due to a decrease in gasoline and distillate selling prices, partially offset by an increase in gasoline and distillate sales volumes of 24 million gallons. The $261 million increase in the first nine months of 2013 was primarily due to an increase in gasoline and distillate sales volumes of 88 million gallons, partially offset by a decrease in gasoline and distillate selling prices. Gasoline and distillate selling prices averaged $3.47 per gallon and $3.54 per gallon in the third quarter and first nine months of 2013 compared to $3.63 per gallon and $3.59 per gallon in the third quarter and first nine months of 2012. The Speedway

segment also had higher merchandise sales in the third quarter and first nine months of 2013. The increases in gasoline and distillate sales volumes and merchandise sales in the first nine months of 2013 were primarily due to the acquisitions of convenience stores in 2013 and 2012.
Pipeline Transportation segment revenue increased $21 million in the third quarter and $76 million in the first nine months of 2013 compared to the third quarter and first nine months of 2012, primarily due to higher transportation tariffs from our crude oil pipelines, resulting from higher crude oil volumes transported and increased tariff rates in the last half of 2012. Crude oil pipeline throughput volumes increased 181 mbpd in the third quarter and 158 mbpd for the nine months of 2013 compared to the corresponding 2012 periods. Higher average prices received on our refined products pipelines were offset by decreased volumes transported during the third quarter and first nine months of 2013. Refined products pipeline throughput volumes decreased 131 mbpd in the third quarter and 42 mbpd for the nine months of 2013 compared to the corresponding 2012 periods.

Refining & Marketing segment income from operations decreased $1.46 billion in the third quarter and $1.72 billion in the first nine months of 2013 compared to the third quarter and first nine months of 2012, primarily due to decreases in refining and marketing gross margins, which averaged $2.55 per barrel and $5.42 per barrel in the third quarter and first nine months of 2013 compared to $13.12 per barrel and $10.92 per barrel in the third quarter and first nine months of 2012. The main factors contributing to the decreases were narrower crude oil differentials, lower crack spreads and lower product price realizations compared to the spot market product prices used in the LLS crack spread calculation.
The sweet and sour crude oil differentials narrowed by $5.67 per barrel in the third quarter and $3.90 per barrel in the first nine months of 2013. In addition, the LLS-WTI crude oil differentials narrowed by $13.05 per barrel in the third quarter and $4.97 per barrel in the first nine months of 2013. The Chicago and USGC LLS 6-3-2-1 blended crack spread decreased $5.29 per barrel and $0.66 per barrel in the third quarter and first nine months of 2013. These impacts were partially offset by increases in refinery throughputs and refined product sales volumes related to the Galveston Bay refinery acquired in February 2013.

Refinery direct operating costs in the Refining & Marketing gross margin increased $0.55 per barrel and $0.69 per barrel of total refinery throughputs in the third quarter and first nine months of 2013 compared to the third quarter and first nine months of 2012, which includes increases in other manufacturing costs of $0.94 per barrel and $0.87 per barrel, respectively. The increases were primarily attributable to the addition of the Galveston Bay refinery, which had higher operating costs per barrel of throughput than the average of our other six refineries due to its greater level of complexity.

We purchase RINs to satisfy a portion of our Renewable Fuel Standard (“RFS2”) compliance. Our cost of purchasing RINs increased to $78 million and $185 million in the third quarter and first nine months of 2013 from $4 million and $70 million in the same periods of 2012, primarily due to higher ethanol RIN prices. The increase in the third quarter was also partially due to higher biomass-based diesel RIN prices and the increase in the first nine months was also partially due to an increase in the biomass-based diesel volumetric obligation.
Speedway segment income from operations increased $26 million in the third quarter and $59 million in the first nine months of 2013 compared to the third quarter and first nine months of 2012, primarily due to increases in our gasoline and distillate gross margin and our merchandise gross margin, partially offset by less income due to the absence of operating asset sales and higher operating expenses. The increases in our gasoline and distillate gross margin were primarily due to $0.0304 and $0.0202 increases in our gross margin per gallon along with higher sales volumes. The increases in the merchandise gross margin were primarily due to higher merchandise sales. The increases in gasoline and distillate sales volumes, merchandise sales and expenses in the first nine months of 2013 primarily related to an increase in the number of convenience stores.

Pipeline Transportation segment income from operations increased $2 million in the third quarter and $19 million in the first nine months of 2013 compared to the third quarter and first nine months of 2012. The increases primarily reflect higher transportation tariffs, partially offset by higher operating and depreciation expenses.
Corporate and other unallocated expenses decreased $15 million in the third quarter and $55 million in the first nine months of 2013 compared to the third quarter and first nine months of 2012. The decreases were primarily due to lower unallocated employee benefit and information technology expenses.
We recognized a gain of $183 million during the third quarter and first nine months of 2012 associated with the settlement agreement with the buyer of our Minnesota Assets, which included $86 million of the deferred gain that was recorded when the sale transaction was originally closed. See Note 6 to the unaudited consolidated financial statements for additional information on the Minnesota Assets sale and subsequent settlement with the buyer.
We recorded pretax pension settlement expenses of $23 million in the third quarter and $83 million in the first nine months of 2013 resulting from the level of employee lump sum retirement distributions that occurred during those periods, compared to $33 million in the third quarter and $116 million in the first nine months of 2012.

Net cash provided by operating activities decreased $399 million in the first nine months of 2013 compared to the first nine months of 2012, primarily due to a decrease in net income, partially offset by favorable changes in working capital compared to 2012. Changes in working capital were a net $330 million use of cash in the first nine months of 2013 compared to a net $1.35 billion use of cash in the first nine months of 2012. The $330 million use of cash from working capital changes in the first nine months of 2013 was primarily due to increases in crude oil and refined product inventory volumes and current receivables, partially offset by an increase in accounts payable and accrued liabilities. Changes in inventories were a $1.33 billion use of cash in the first nine months of 2013, primarily due to increases in crude oil and refined product inventory volumes. Current receivables increased $983 million from year-end 2012, primarily due to higher refined product receivable volumes attributable to an increase in refined product sales volumes associated with the Galveston Bay refinery acquired in February 2013, and an increase in income taxes receivable associated with federal income taxes. Accounts payable increased $2.18 billion from year-end 2012, primarily due to higher crude oil payable volumes related to the addition of the Galveston Bay refinery in February 2013 and higher crude oil prices at the end of the third quarter of 2013 compared to year-end 2012. The $1.35 billion use of cash from working capital changes in the first nine months of 2012 was primarily due to a decrease in accounts payable and accrued liabilities resulting primarily from a reduction in crude oil payable volumes and an increase in inventories resulting primarily from interim seasonal increases in refined products and crude oil inventory volumes. Partially offsetting these uses of cash was a decrease in accounts receivable primarily caused by lower crude oil receivable volumes, partially offset by higher refined products receivables.
Net cash used in investing activities increased $1.22 billion in the first nine months of 2013 compared to the first nine months of 2012, primarily due to the Galveston Bay Refinery and Related Assets acquisition in February 2013, partially offset by lower capital expenditures in 2013 due to the completion of the Detroit refinery heavy oil upgrading and expansion project in late 2012.
The consolidated statements of cash flows exclude changes to the consolidated balance sheets that did not affect cash. A reconciliation of additions to property, plant and equipment to reported total capital expenditures and investments follows.

(d) 
Includes capitalized interest of $15 million and $95 million for the nine months ended September 30, 2013 and 2012, respectively.
The acquisition of the Galveston Bay Refinery and Related Assets comprised 60 percent of our total capital spending in the first nine months of 2013. The Detroit refinery heavy oil upgrading and expansion project, which we completed in the fourth quarter of 2012, comprised 56 percent (excluding capitalized interest associated with this project) of our Refining & Marketing segment capital spending in the first nine months of 2012.
Net cash used in financing activities increased $1.53 billion in the first nine months of 2013 compared to the first nine months of 2012. The uses of cash for both periods were primarily for common stock repurchases under our share repurchase plans and dividend payments.
Cash used in common stock repurchases under the share repurchase plans authorized by our board of directors increased $1.49 billion in the first nine months of 2013 compared to the first nine months of 2012. During the first nine months of 2013, we paid $2.34 billion to repurchase 30 million common shares through open market repurchases compared to $850 million paid to repurchase 20 million shares under an ASR program during the nine months of 2012. See Note 8 to the unaudited consolidated financial statements for further discussion of the share repurchase plans.
Cash used in dividend payments increased $67 million in the first nine months of 2013 compared to the first nine months of 2012, primarily due to an average 9 cent per share increase in our quarterly dividend payment for the nine months, partially offset by a decrease in the number of outstanding shares of our common stock attributable to share repurchases. Our dividend payments totaled $1.12 per common share in the first nine months of 2013 compared to $0.85 per common share in the first nine months of 2012.

(a) 
Excludes MPLX’s $500 million revolving credit agreement, which was undrawn as of September 30, 2013.
Because of the alternatives available to us, including internally generated cash flow and access to capital markets, we believe that our short-term and long-term liquidity is adequate to fund not only our current operations, but also our near-term and long-term funding requirements, including capital spending programs, the repurchase of shares of our common stock, dividend payments, defined benefit plan contributions, repayment of debt maturities and other amounts that may ultimately be paid in connection with contingencies.
Our revolving credit agreement (the “MPC Credit Agreement”) and MPLX’s revolving credit agreement (the “MPLX Credit Agreement”) contain representations and warranties, affirmative and negative covenants and events of default that we consider usual and customary for agreements of these types. The financial covenant included in the MPC Credit Agreement requires us to maintain, as of the last day of each fiscal quarter, a ratio of Consolidated Net Debt to Total Capitalization (as defined in the MPC Credit Agreement) of no greater than 0.65 to 1.00. As of September 30, 2013, we were in compliance with this debt covenant with a ratio of Consolidated Net Debt to Total Capitalization of 0.18 to 1.00, as well as the other covenants contained in the MPC Credit Agreement.
The financial covenant included in the MPLX Credit Agreement requires MPLX to maintain a ratio of Consolidated Total Debt (as defined in the MPLX Credit Agreement) as of the end of each fiscal quarter to Consolidated EBITDA (as defined in the MPLX 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). As of September 30, 2013, MPLX was in compliance with this debt covenant with a ratio of Consolidated Total Debt to Consolidated EBITDA of 0.1 to 1.0, as well as the other covenants contained in the MPLX Credit Agreement.
Our intention is to maintain an investment grade credit profile. As of September 30, 2013, the credit ratings on our senior unsecured debt were at or above investment grade level as follows.
 
Rating Agency                                    
  
Rating                                     
Moody’s
  
Baa2 (positive outlook)
Standard & Poor’s
  
BBB (stable outlook)
The ratings reflect the respective views of the rating agencies. Although it is our intention to maintain a credit profile that supports an investment grade rating, there is no assurance that these ratings will continue for any given period of time. The ratings may be revised or withdrawn entirely by the rating agencies if, in their respective judgments, circumstances so warrant.
Neither the MPC Credit Agreement, the MPLX Credit Agreement nor our trade receivables securitization facility contain credit rating triggers that would result in the acceleration of interest, principal or other payments in the event that our credit ratings are downgraded. However, any downgrades of our senior unsecured debt to below investment grade ratings would increase the applicable interest rates, yields and other fees payable under the MPC Credit Agreement and our trade receivables securitization facility. In addition, a downgrade of our senior unsecured debt rating to below investment grade levels could, under certain circumstances, decrease the amount of trade receivables that are eligible to be sold under our trade receivables securitization facility, impact our ability to purchase crude oil on an unsecured basis and could result in us having to post a letter of credit under an existing transportation services agreement.

Capital Requirements
We have a capital and investment budget for 2013 of $1.62 billion, excluding capitalized interest and the purchase price for the Galveston Bay Refinery and Related Assets. The budget includes spending on refining, retail marketing, transportation, logistics and brand marketing projects as well as amounts designated for corporate activities. During the nine months ended September 30, 2013, our capital expenditures and investments were $891 million, excluding capitalized interest and the purchase price for the Galveston Bay Refinery and Related Assets. There have been no material changes to our 2013 capital and investment budget since our Annual Report on Form 10-K for the year ended December 31, 2012 was filed. We continuously evaluate our capital budget and make changes as conditions warrant.
Pursuant to the purchase and sale agreement for the Galveston Bay Refinery and Related Assets, we may be required to pay to the seller a contingent earnout of up to an additional $700 million over six years, subject to certain conditions. See Note 4 to the unaudited consolidated financial statements.
During the nine months ended September 30, 2013, we made contributions of $158 million to our funded pension plans. We may make additional contributions to our funded pension plans in 2013 depending on the anticipated funding status and plan asset performance.
On October 30, 2013, our board of directors approved a 42 cents per share dividend, payable December 10, 2013 to stockholders of record at the close of business on November 20, 2013.
On January 30, 2013, we announced that our board of directors approved an additional $2.0 billion share repurchase authorization. The board also extended the remaining $650 million share repurchase authorization for a total outstanding authorization of $2.65 billion through December 2014. On September 26, 2013, we announced that our board of directors approved an additional $2.0 billion share repurchase authorization through September 2015. During the first nine months of 2013, the final shares from the $500 million ASR program were delivered to us and we paid $2.34 billion to acquire 30 million common shares through open market share repurchases. During the third quarter of 2013, we also entered into agreements to acquire additional common shares for $42 million, which were settled in early October 2013. At September 30, 2013, the initial $2.0 billion repurchase authorization announced on February 1, 2012 and extended on January 30, 2013 had been exhausted. As of September 30, 2013, we had total outstanding repurchase authorizations pursuant to the authorizations announced on January 30, 2013 and September 26, 2013 of $2.31 billion, of which $309 million expires in December 2014 and $2.0 billion expires in September 2015.
We may utilize various methods to effect additional repurchases, which could include open market purchases, negotiated block transactions, ASRs or open market solicitations for shares, some of which may be effected through Rule 10b5-1 plans. The timing and amount of future repurchases, if any, will depend upon several factors, including market and business conditions, and such repurchases may be discontinued at any time.
The above discussion of the share repurchase authorizations includes forward-looking statements. Factors that could affect the share repurchase plan and its timing include, but are not limited to, business conditions, availability of liquidity and the market price of our common stock. These factors, among others, could cause actual results to differ materially from those set forth in the forward-looking statements.

These contracts include variable price arrangements with estimated prices to be paid primarily based on current market conditions.

Primarily includes contracts to purchase services such as utilities, supplies and various other maintenance and operating services.
(g) 
Primarily includes obligations for pension and other postretirement benefits including medical and life insurance, which we have estimated through 2022. See Note 20 to the unaudited consolidated financial statements.
Off-Balance Sheet Arrangements
Off-balance sheet arrangements comprise those arrangements that may potentially impact our liquidity, capital resources and results of operations, even though such arrangements are not recorded as liabilities under accounting principles generally accepted in the United States. Although off-balance sheet arrangements serve a variety of our business purposes, we are not dependent on these arrangements to maintain our liquidity and capital resources, and we are not aware of any circumstances that are reasonably likely to cause the off-balance sheet arrangements to have a material adverse effect on liquidity and capital resources.
We have provided various guarantees related to equity method investees. In conjunction with our spinoff from Marathon Oil, we entered into various indemnities and guarantees to Marathon Oil. These arrangements are described in Note 22 to the unaudited consolidated financial statements.
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 credit ratings by rating agencies. The discussion of liquidity and capital resources above also contains forward-looking statements regarding expected capital and investment spending. The forward-looking statements about our capital and investment budget are based on current expectations, estimates and projections and are not guarantees of future performance. Actual results may differ materially from these expectations,

Table of Contents

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 refinery feedstocks and refined products, actions of competitors, delays in obtaining necessary third-party approvals, changes in labor, materials, and equipment costs and availability, planned and unplanned outages, the delay of, cancellation of or failure to implement planned capital projects, project cost overruns, disruptions or interruptions of our refining 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
We believe that transactions with related parties were conducted under terms comparable to those with unrelated parties.
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 the age and location of its operating facilities, marketing areas, production processes and whether it is also engaged in the petrochemical business or the marine transportation of crude oil and refined products.
On January 25, 2013, the U.S. Court of Appeals for the D.C. circuit vacated the 2012 cellulosic biofuel requirements under the RFS2 program. In light of this ruling, the Environmental Protection Agency (“EPA”) is reconsidering and is anticipated to lower the 2011 and has subsequently eliminated the 2012 cellulosic biofuel requirements under the RFS2 program. The EPA also has proposed a rule establishing a quality assurance program for RINs purchased to help meet the annual biofuel requirements under the RFS2 program. This rule should be finalized later this year and is aimed at reducing the chances that RINs are fraudulently created or sold.
On March 29, 2013, the EPA announced its proposed Tier 3 fuel standards. The proposed Tier 3 fuel standards require, among other things, a lower annual average sulfur level in gasoline to no more than 10 parts per million beginning in calendar year 2017. MPC and its trade organizations have submitted public comments on the standards and the agency is expected to finalize the Tier 3 fuel standards later this year. Our cost of compliance may be material; however, we will likely not be able to reasonably estimate our compliance costs until we have had time to review the final standards and develop our compliance plans.
There have been no other significant changes to our environmental matters and compliance costs during the nine months ended September 30, 2013.
Critical Accounting Estimates
The preparation of financial statements in accordance with US GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses during the respective reporting periods. Accounting estimates are considered to be critical if (1) the nature of the estimates and assumptions is material due to the levels of subjectivity and judgment necessary to account for highly uncertain matters or the susceptibility of such matters to change; and (2) the impact of the estimates and assumptions on financial condition or operating performance is material. Actual results could differ from the estimates and assumptions used. The following critical accounting estimates have been updated since our Annual Report on Form 10-K for the year ended December 31, 2012 was filed.

Fair Value Estimates
Acquisitions
In accounting for business combinations, acquired assets and liabilities are recorded based on estimated fair values as of the date of acquisition. The excess or shortfall of the purchase price when compared to the fair value of the net tangible and identifiable intangible assets acquired, if any, is recorded as goodwill or a bargain purchase gain, respectively. A significant amount of judgment is involved in estimating the individual fair values of property, plant and equipment, intangible assets and other assets and liabilities. We use all available information to make these fair value determinations and, for certain acquisitions, engage third-party consultants for assistance.

44

Table of Contents

The fair value of assets and liabilities as of the acquisition date are often estimated using a combination of approaches, including the income approach, which requires us to project related future cash inflows and outflows and apply an appropriate discount rate; the cost approach, which requires estimates of replacement costs and depreciation and obsolescence estimates; and the market approach which uses market data and adjusts for entity specific differences. The estimates used in determining fair values are based on assumptions believed to be reasonable but which are inherently uncertain. Accordingly, actual results may differ from the projected results used to determine fair value. See Note 4 to the unaudited consolidated financial statements for additional information on our acquisitions.
Derivatives
We record all derivative instruments at fair value. All of our commodity derivatives are cleared through exchanges which provide active trading information for identical derivatives and do not require any assumptions in arriving at fair value.
Accounting Standards Not Yet Adopted
As of September 30, 2013, there are no accounting standards that have not yet been adopted.

For a detailed discussion of our risk management strategies and our derivative instruments, see Item 7A. Quantitative and Qualitative Disclosures about Market Risk in our Annual Report on Form 10-K for the year ended December 31, 2012.
See Notes 15 and 16 to the unaudited consolidated financial statements for more information about the fair value measurement of our derivatives, as well as the amounts recorded in our consolidated balance sheets and statements of income. We do not designate any of our commodity derivative instruments as hedges for accounting purposes.

We remain at risk for possible changes in the market value of commodity derivative instruments; however, such risk should be mitigated by price changes in the underlying physical commodity. Effects of these offsets are not reflected in the above sensitivity analysis.
We evaluate our portfolio of commodity derivative instruments on an ongoing basis and add or revise strategies in anticipation of changes in market conditions and in risk profiles. Changes to the portfolio after September 30, 2013 would cause future IFO effects to differ from those presented above.

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.

(d)

At September 30, 2013, our portfolio of long-term debt was substantially comprised of fixed-rate instruments. Therefore, the fair value of the portfolio is relatively sensitive to interest rate fluctuations. Our sensitivity to interest rate declines and corresponding increases in the fair value of our debt portfolio unfavorably affects our results of operations and cash flows only when we elect to repurchase or otherwise retire fixed-rate debt at prices above carrying value.

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 our management, including our chief executive officer and chief financial officer. Based upon that evaluation, the chief executive officer and chief financial officer concluded that the design and operation of these disclosure controls and procedures were effective as of September 30, 2013, 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, 2013, 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
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. Specific matters discussed below are either new proceedings or material developments in proceedings previously reported.
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
In May 2013, the Michigan Department of Environmental Quality ("MDEQ") issued a Notice of Enforcement to Marathon Petroleum Company LP for alleged violations associated with exceeding various air permit limits. In October 2013, we self-disclosed potential similar exceedences that may occur by the end of 2013. We expect to resolve these violations through revisions in the air permit limits. The resolution of this matter may result in a penalty in excess of $100,000.
We are involved in a number of other environmental proceedings arising in the ordinary course of business. While the 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, 2012.

Through January 30, 2013, the total value of share repurchases completed pursuant to this initial repurchase authorization was $1.35 billion. On January 30, 2013, we announced that our board of directors extended the duration of the existing $650 million repurchase authorization and approved an additional $2.0 billion share repurchase authorization, both to expire on December 31, 2014. On September 26, 2013, we announced that our board of directors approved an additional $2.0 billion share repurchase authorization through September 30, 2015, resulting in $6.0 billion of total share repurchase authorizations since January 1, 2012.
