Report of Independent Registered Public Accounting Firm



To the Participants and Plan Administrator of
Marathon Oil Company Thrift Plan

We have audited the accompanying statements of net assets available for benefits of the Marathon Oil Company Thrift Plan (the “Plan”) as of December 31, 2016 and 2015, and the related statement of changes in net assets available for benefits for the year ended December 31, 2016. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the auditing standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by the Plan’s management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. 

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2016 and 2015, and the changes in net assets available for benefits for the year ended December 31, 2016, in conformity with accounting principles generally accepted in the United States of America.

The supplemental schedule listed in the table of contents has been subjected to audit procedures performed in conjunction with the audit of the Plan’s financial statements. The supplemental schedule is the responsibility of Plan management. Our audit procedures included determining whether the supplemental schedule reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental schedule. In forming our opinion on the supplemental schedule, we evaluated whether the supplemental schedule, including its form and content, is presented in conformity with the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, the supplemental schedule is fairly stated, in all material respects, in relation to the financial statements as a whole.

1.Description of Plan
The following brief description of the Marathon Oil Company Thrift Plan (the “Plan”) provides only general information. Participants should refer to the Summary Plan Description or the Plan Document for a more complete description of the Plan's provisions. Effective as of January 1, 2014, Marathon Oil Company (the “Company”) amended and restated the Plan in its entirety.  The provisions of this amended and restated Plan apply to determine eligibility, contributions, distributions, investments, and other Plan activities.
General
The Plan is a defined contribution thrift savings plan. The Plan covers substantially all regular and casual employees of the following entities, which are participating employers in the Plan: Marathon Oil Corporation (“MRO”), the Company, and Marathon Service Company. All of these participating employers, other than MRO, are wholly owned subsidiaries of MRO. An eligible employee may participate in the Plan by making contributions to the Plan. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”).
Contributions
Participants may elect to make contributions from 1 percent to a maximum of 18 percent of their gross pay consisting of after-tax contributions, or 1 percent to a maximum of 25 percent of their gross pay consisting of pre-tax contributions, Roth 401(k) contributions, or a combination of both. In addition, catch up contributions are allowed under the Plan, which allow for additional contributions for participants who have attained age 50 before the close of the Plan year as permitted under the Internal Revenue Code (the “Code”). An active participant may make any combination of after-tax and pre-tax/Roth 401(k) payroll contributions provided that the participant does not exceed the maximums permitted under the Code or the limits set forth in the Plan document.
The contributions of highly compensated employees are subject to additional limitations pursuant to the provisions of Code Sections 401(k) and 401(m). Compensation of a participant taken into account under the Plan is limited to $265,000 for 2016, as provided in Code Section 401(a)(17).
Participants may also make rollover contributions or direct-plan transfer contributions of qualified distributions from the qualified plans of the Company, its subsidiaries, its affiliates, and any other qualified plans or conduit individual retirement accounts (“IRA”) upon specific authorization and subject to such terms and conditions as set forth by the Plan Administrator.
To the extent that the Company has accumulated earnings and profits, the Company will match on a dollar for dollar basis each participant's after-tax or pre-tax/Roth 401(k) contributions to the Plan up to an aggregate of 7 percent of each participant's eligible gross pay.
Valuation of Participant Accounts
Each participant's account is credited with the participant's contribution and allocations of (a) the Company's contributions and (b) Plan earnings (losses) based on the participant's relative investment holdings. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account.
Vesting
Participants are fully and immediately vested in their contributions plus actual earnings thereon. Participants become fully vested in the Company contributions, plus actual earnings thereon, in any of the following ways: upon retirement under the Retirement Plan of the Company; at death; after three years of vesting service with the Company or another employer within the controlled group of MRO; or upon attainment of age 65.

Participant Loans
Participants may borrow from their fund accounts at a minimum of $500 up to a maximum equal to the lesser of $50,000 or 50 percent of their account balance. The loans are collateralized by the balance in the participant's account and bear interest rates that ranged from 3.25 percent to 8.25 percent throughout 2016, determined in accordance with Plan provisions. Principal and interest is paid ratably through payroll deductions for active employees and through automatic payments for participants not receiving pay and retirees.
Payment of Benefits
On termination of service, unless a participant elects otherwise or as required by the Code, a participant will receive a lump-sum amount equal to the value of the participant's vested interest in his or her account. The participant alternatively may elect to defer the commencement of benefits until a date no later than the April 1 immediately following the calendar year in which such participant attains age 70-1/2. In accordance with the provisions of the Code, mandatory distributions equal to or less than $5,000 but greater than $1,000 require automatic rollover to an IRA for participants who fail to make an active election otherwise available under the Plan. A retired member or a spouse beneficiary member may withdraw, during any year, all or any portion of the remaining balance in his or her account, subject to certain restrictions. An installment settlement option is available to retired participants subject to certain requirements and restrictions.
Forfeitures
Non-vested participants whose services with the Company have been terminated will forfeit their entire Company-matching contribution and earnings thereon when either of the following takes place: (1) they remove their participant contributions from the Plan, or (2) they do not regain employment within five years of termination. Company contributions and earnings thereon are eligible for reinstatement, should a member be rehired prior to the limitation indicated under the Plan. Total forfeitures of $387,970 for the year ended December 31, 2016 were used to reduce employer matching contributions made to the Plan. The forfeited balance held in the Plan as of December 31, 2016 and 2015 was $35,259 and $284,002, respectively.
Investment Options
Effective August 8, 2016, the investment option Morgan Stanley Institutional Fund Trust Mid Cap Growth Portfolio Class IS was replaced with Baird MidCap Fund Institutional Class. This change was communicated to participants in July 2016.
Also, effective August 8, 2016, the Plan's designated default investment option which consists of the FIAM Target Date Commingled Pools Class V was replaced with FIAM Target Date Commingled Pools Class Q. The new share class offers the same investment strategy and risk but at a lower cost to participants. In addition, FIAM Target Date 2060 Commingled Pool Class Q was added as an investment option. These changes were communicated to participants in July 2016.
Effective December 30, 2016, MRO stock became a frozen investment option in the Plan, which means that participants can no longer invest future contributions in MRO stock or exchange from another investment option into MRO Stock. Any individual company stock poses a greater potential investment risk than investment in mutual funds and other diversified investment options, so this change was made to help participants reduce risk in their Plan accounts. This change was communicated to participants in July 2016 and November 2016.

Summary of Significant Accounting Policies

Basis of Accounting
The financial statements of the Plan are prepared under the accrual basis of accounting in accordance with accounting principles generally accepted in the United States of America (“GAAP”).
Use of Estimates
The preparation of financial statements in conformity with GAAP requires the Plan's management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and changes therein and disclosure of contingent assets and liabilities. Actual results could differ from those estimates.
Reclassifications
Certain reclassifications have been made to the 2015 financial statements to conform to the 2016 financial statement presentation. These reclassifications had no effect on changes in net assets available for benefits.
Investment Valuation and Income Recognition
Investments are reported at fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. See Note 4 for discussion of fair value measurements.

Fully benefit-responsive investment contracts held by a defined-contribution plan are no longer required to disclose the fair value with and adjustment to contract value on the statement of net assets available for benefits, per ASU 2015-12 Part I, adopted in 2016. They are now reported at contract value, which is the relevant measurement attribute of fully benefit-responsive investment contracts, because contract value is the amount participants would receive if they were to initiate permitted transactions under the terms of the Plan. The statements of net assets available for benefits present the contract value of the investment contracts, and the statement of changes in net assets available for benefits is prepared on a contract value basis.

Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. Net appreciation includes gains and losses on investments bought and sold as well as held during the year. Investment related expenses are also included in net appreciation of fair value of investments.

Payment of Benefits
Benefits are recorded when paid.
Notes Receivable from Participants
Notes receivable from participants represent participant loans that are recorded at their unpaid principal balance plus any accrued but unpaid interest. Interest income on notes receivable from participants is recorded when it is earned. No allowance for credit losses has been recorded as of December 31, 2016 and 2015.

Administration of Plan Assets
All costs, expenses, and fees incurred in administering the Plan, to the extent not paid by the Company, are incurred by the participants. Fees or charges for investment management services are not paid by the Company but are borne by the participants electing such services. Any taxes applicable to the participants' account are charged or credited to the participants' account by Fidelity Investments Institutional Operations Company, Inc ("FIIOS").

The Stable Value Fund is a combination of Fidelity's Managed Income Portfolio II ("MIP II"), a stable value commingled pool of the Fidelity Group Trust for Employee Benefit Plans, and stable value assets previously purchased by the Fund. Any fees charged by Fidelity Management Trust Company are deducted from the interest earned by Plan members in the Stable Value Fund. The total amount of fees charged by Fidelity Management Trust Company for 2016 in connection with management of assets within the Stable Value Fund was $825,859.

3.
Accounting Standards Update

In July 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") No. 2015-12, “Plan Accounting: defined benefit pension plans (Topic 960), defined contribution pension plans (Topic 962), health and welfare benefit plans (Topic 965): (Part I) fully benefit-responsive investment contracts, (Part II) plan investment disclosures, (Part III) measurement date practical expedient.” Part I requires a benefit plan to use contract value as the only measurement for fully benefit-responsive investment contracts on the statement of net assets available for benefits. Part II eliminates the requirements to disclose individual investments that represent 5 percent or more of net assets available for benefits and the net appreciation or depreciation in fair value of investments by general type. Part II also simplifies the level of disaggregation of investments that are measured using fair value. Plans will continue to disaggregate investments that are measured using fair value by general type; however, plans are no longer required to also disaggregate investments by nature, characteristics and risks. Further, the disclosure of information about fair value measurements shall be provided by general type of plan asset. Part III is not applicable to the Plan. These amendments are effective for fiscal years beginning after December 15, 2015 with early adoption permitted. The Plan is required to apply Part I and II retrospectively for all statements presented. The amendment was adopted in 2016 and impacts both the presentation of the investments on the statement of net assets available for benefits and the disclosures.

In May 2015, the FASB issued ASU No. 2015-07, “Disclosures for Investments in Certain Entities That Calculate Net Asset Value ("NAV") per Share (or its equivalent).” ASU 2015-07 removes the requirement to include investments in the fair value hierarchy for which fair value is measured using the net asset value per share practical expedient under Accounting Standard Codification ("ASC") 820. ASU 2015-07 is effective for the Plan retrospectively for the year ending December 31, 2016 with early adoption permitted. The amendment was adopted in 2016 and has an impact on the disclosures only.
  
4.
Fair Value Measurements

The FASB ASC 820, Fair Value Measurements and Disclosures, establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. There are three approaches for measuring the fair value of assets and liabilities: the market approach, the income approach, and the cost approach, each of which includes multiple valuation techniques. This hierarchy consists of three broad levels:
Level 1 inputs consist of unadjusted quoted prices in active markets for identical assets and liabilities and have the highest priority;
Level 2 inputs consist of quoted prices for similar assets or liabilities in active markets, or quoted prices for identical or similar assets or liabilities in inactive markets, or inputs other than quoted prices that are observable for the asset or liability, or inputs that are derived principally from or corroborated by observable market data by correlation or other means;
Level 3 inputs are unobservable and significant to the fair value measurement and have the lowest priority.

The Plan's investments are reported at fair value in the accompanying statements of net assets available for benefits with the exception of the benefit-responsive contracts which are valued at contract value (see Note 2). The methods used to measure fair value may produce an amount that may not be indicative of net realizable value or reflective of future fair values. Furthermore, although the Plan believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. The following provides a description of the valuation techniques employed for each major plan asset class at December 31, 2016 and 2015.
Common stock - Investments in common stocks are valued using a market approach at the closing price reported in an active market and is therefore considered Level 1.

Brokeragelink Investments - Participants can open a self-directed brokerage account within the Plan that allows participants to buy and sell stocks, corporate bonds, treasury securities, and other securities on the active market. These assets are considered Level 1.

Mutual funds - Investments in mutual funds, including money market mutual funds, are valued using a market approach at the net asset value of shares held. The net asset value is generally based on prices from a public exchange, which is normally the principal market on which the investments are traded, and is considered Level 1. Interest-bearing cash includes cash on deposit.

Investments valued at Net Asset Value per Share Practical Expedient

The common collective trusts ("CCTs") are reported in the fair value table without leveling, as ASU 2015-07 was adopted in 2016. This accounting standard removes the requirement to include investments in the fair value hierarchy for which fair value is measured using the net asset value per share practical expedient under accounting standards codification ASC 820.

Common Collective Trusts - The FIAM Target Date Commingled Pools, the Fidelity Growth Company Commingled Pool, and the portion of the stable value fund that is in the MIP II are CCTs. The target date pools seek active return until the pool's targeted retirement year. Thereafter, the pool's objective will be capital preservation. These pools invest in a diversified portfolio of equity, fixed income and/or short-term products. The underlying pools may use futures, options, swaps, and exchange traded funds to remain fully invested, while being able to respond to participant cash flows and to take advantage of changes in interest rates and other factors affecting value. Each target date pool's target asset allocation percentages will become more conservative over time by reducing allocations to equity and increasing allocations to fixed income and/or short-term products. Each target date pool's retirement date target allocation will be approximately 50 percent equity index, 40 percent fixed income index, and 10 percent short term. The growth company CCT normally invests primarily in common stocks of domestic and foreign issuers with the potential for above-average growth. Growth may be measured by factors such as earnings or revenue. There are no redemption restrictions on any of these CCTs. There are also no unfunded commitments attributable to any of the CCTs. Investment in CCTs are valued using a market approach at the net asset value of units held, but investment opportunities in such funds are limited to institutional investors on behalf of defined contribution plans.

5. Stable Value Fund (Fully Benefit-Responsive Investment Contract)

The Plan has an interest in a Stable Value Fund that comprised approximately 32 percent and 32 percent of total Plan investments at December 31, 2016 and 2015, respectively. The Stable Value Fund has investments in fully benefit-responsive investment contracts issued by insurance companies and other financial institutions.

As a Synthetic Investment Contract (SIC) is fully benefit-responsive, contract value is the relevant measurement attribute for that portion of the net assets available for benefits attributable to these contracts. Contract value represents contributions made under the contract, plus earnings, less Plan withdrawals and administrative expenses. Participants may ordinarily direct the withdrawal or transfer of all or a portion of their investment at contract value. In a SIC structure, the underlying investments are directly owned by the Stable Value Fund and held in a trust for Plan participants. The Stable Value Fund purchases a wrapper contract from an insurance company or bank to provide principal preservation and steady income to the Plan. The wrapper contract amortizes the realized and unrealized gains and losses on the underlying fixed income investments, typically over the duration of the investment, through adjustments to the future interest crediting rate.

The issuer of the wrapper contract provides assurance that the adjustments to the interest crediting rate do not result in a future interest crediting rate that is less than zero. The contract crediting rates associated with the SICs are typically reviewed and reset, if needed, on a quarterly basis. The key factors that influence future interest crediting rates include: the level of market interest rates; the amount and timing of participant contributions, transfers, withdrawals into/out of the contract; the investment returns generated by the fixed income investments that back the wrapper contract; and the duration of the underlying investments backing the wrapper contract.

A wrap issuer may terminate a wrapper contract in accordance with the terms of the contract. A wrap issuer may also terminate a wrapper contract if Fidelity Management Trust Company investment management authority over the Stable Value Fund is limited or terminated as well as if all of the terms of the wrapper contract fail to be met. In addition, wrapper contracts limit the ability of the Stable Value Fund to transact at contract value upon the occurrence of certain events (e.g., complete or partial termination of the plan, early retirement program, or the Plan's failure to qualify under Section 401(a) or Section 401(k) of the Code). In light of the occurrence of a partial termination during 2015, further explained in Note 8, the Plan Administrator made the changes to the Stable Value Fund described above in order to protect the interests of plan participants who have invested in the Stable Value Fund.

7. Party-in-Interest Transactions
The Trustee provides certain accounting and administrative services to the Plan for which approximately $65,039 and $44,188 of expenses were charged for the years ended December 31, 2016 and 2015, respectively. Certain Plan investments, amounting to $776,262,362 and $835,912,616 at December 31, 2016 and 2015, respectively, are managed by affiliates of the Trustee.
Certain employees and officers of the Company, who may also participate in the Plan, perform administrative services to the Plan at no cost.
Shares of MRO common stock previously could be purchased directly from MRO or on the open market. MRO common stock held in the Plan as of December 31, 2016 and 2015 was $38,308,732 and 28,638,024, respectively. During 2016, all shares of the MRO common stock were purchased on the open market until December 30, 2016 when MRO stock became a frozen investment option in the Plan. Certain Plan investments are shares of mutual funds managed by FIIOS, and the CCTs are managed by FIAM (Fidelity Institutional Asset Management). Fidelity Management Trust Company is the trustee as defined by the Plan and, therefore, these transactions qualify as party-in-interest.
The Plan also holds notes receivable representing participant loans that qualify as party-in-interest transactions.
All party-in-interest transactions noted above are deemed exempt from the prohibited transaction rules.

8. Plan Termination
In 2015, the Company implemented multiple rounds of workforce reductions that created a reduction in Plan participation in excess of 20% of active employees participating in the Plan. As described in IRS Revenue Ruling 2007-28, a partial termination is presumed to occur with respect to a plan if 20% of employees participating in the plan are terminated. Because the reductions in force affected more than 20% of employees participating in the Plan, a partial termination occurred for tax purposes. A partial termination of the Plan did not occur in 2016.
Although it has not expressed any interest to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants will become 100 percent vested in their accounts.
9. Tax Status
The Internal Revenue Service (“IRS”) has determined and informed the Plan Administrator by letter dated June 11, 2015, that the Plan, as amended, meets the requirements of Code Section 401(a), and the trust is not subject to tax under present income tax law. This determination letter was applicable for the amendments executed September 24, 2014 and prior. The Plan Administrator and the Plan's tax counsel believe that the Plan, as amended, is designed and is currently being operated in compliance with the applicable requirements of the Code.
GAAP requires the Plan Administrator to evaluate uncertain tax positions taken by the Plan and to recognize a tax liability (or asset) when the position is more likely than not, based on the technical merits, to be sustained upon examination by the IRS. The Plan Administrator has analyzed the tax positions taken by the Plan and has concluded that as of December 31, 2016, there were no uncertain positions taken or expected to be taken that would require recognition of a liability (or asset) or disclosure in the financial statements. The Plan has recognized no interest or penalties related to uncertain tax positions. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress. The Plan Administrator believes it is no longer subject to income tax examinations for years prior to 2013.
10. Risks and Uncertainties
The Plan provides for various investment options. These investments are exposed to various risks, such as interest rate, market and credit. Due to the level of risk associated with certain investment securities and the level of uncertainty related to changes in the value of investment securities, it is possible that changes in the near or long term could materially affect participants' account balances and the amounts reported in the statements of net assets available for benefits and the statement of changes in net assets available for benefits.
11. Subsequent Events
Events and transactions subsequent to the balance sheet date have been evaluated through the date these financial statements were issued for potential recognition or disclosure in the financial statements.
Effective as of January 1, 2017, the Company amended and restated the Plan in its entirety to formally incorporate the MRO stock freeze within the Plan.

A SIC is comprised of two components, an underlying asset and a wrapper contract. The underlying assets are valued at representative quoted market prices. The wrapper contracts are valued by using replacement cost methodology. Contract value represents contributions made under the contract, plus earnings, less Plan withdrawals and administrative expenses. The wrapper contract guarantees the SIC contract value.
