MARATHON OIL CORPORATION
Notes to Consolidated Financial Statements (Unaudited)


1.Basis of Presentation
These consolidated financial statements are unaudited; however, in the opinion of 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 disclosed otherwise. These consolidated financial statements, including notes, have been prepared in accordance with the applicable rules of the SEC and do not include all of the information and disclosures required by U.S. GAAP for complete financial statements.
These interim financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our 2018 Annual Report on Form 10-K. The results of operations for the third quarter and first quarternine months of 2019 are not necessarily indicative of the results to be expected for the full year.
As a result of the announcement to sell our U.K. business in the first quarter of 2019, we have reflected these assets and liabilities as held for sale at March 31, 2019 in the consolidated balance sheet and the consolidated statement of cash flows. The related disclosures in this report exclude these held for sale amounts, unless otherwise noted. This divestiture is discussed in further detail in Note 4.

Reclassifications
We have reclassified certain prior year amounts betweenin the consolidated statements of cash flows within the operating cash flowactivities section to present it on a basis comparable with the current year'syear’s presentation with no impact onto net cash provided by operating activities.
2.    Accounting Standards
Not Yet Adopted
Goodwill standard
In January 2017, the FASB issued a new accounting standards update that eliminates the requirement to calculate the implied fair value of the goodwill (Step 2 of goodwill impairment test under the current guidance) to measure a goodwill impairment charge. We anticipate the standard to require entities to record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value (measure the charge based on Step 1 under the current guidance). This standard is effective for us in the first quarter of 2020 and shall be applied on a prospective basis. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We plan to adopt the standard on a prospective basis, and do not expect a material impact on our consolidated results of operations, financial position or cash flows for prior periods.
Financial instruments – credit losses
In June 2016, the FASB issued a new accounting standards update that changes the impairment model for trade receivables, net investments in leases, debt securities, loans and certain other instruments. The standard requires the use of a forward-looking “expected loss” model as opposed to the current “incurred loss” model. This standard is effective for us in the first quarter of 2020 and will be adopted on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the adoption period. Early adoption is permitted starting January 2019. We are evaluatingcontinue to evaluate the provisions of this accounting standards update and assessing thedo not expect a material impact if any, it may have on our consolidated results of operations, financial position orand cash flows.
Recently Adopted
Lease accounting standard
In February 2016, the FASB issued a new leasing accounting standard, which modified the definition of a lease and established comprehensive accounting and financial reporting requirements for leasing arrangements. It requires lessees to recognize a lease liability and a right-of-use ("ROU"(“ROU”) asset for all leases, including operating leases, with a term of greater than 12 months on the balance sheet. On January 1, 2019, we adopted the new lease accounting standard using the modified retrospective method and applied to all leases that existed as of that date. It does not apply to leases to explore for or use minerals, oil, natural gas and similar non-regenerative resources, including the intangible right to explore for those natural resources and rights to use the land in which those natural resources are contained.


MARATHON OIL CORPORATION
Notes to Consolidated Financial Statements (Unaudited)

The new lease standard requires certain accounting policy decisions while also providing a number of optional practical expedients for transition accounting. Our accounting policies and the practical expedients utilized are summarized below:
Implemented an accounting policy to not recognize any right-of-use assets and lease liabilities related to short-term leases on the balance sheet.
Implemented an accounting policy to not separate the lease and nonlease components for all asset classes, except for vessels.
Elected the package of practical expedients which allows us to not reassess our prior conclusions regarding the lease identification and lease classification for contracts that commenced or expired prior to the effective date.
Elected the practical expedient pertaining to land easements which allows us to continue accounting for existing agreements under the previous accounting policies as nonlease transactions. Any modifications of existing contracts or new agreements will be assessed under the new lease accounting guidance and may become leases in the future.
As a result of the adoption, we recorded approximately $156 million of ROU assets and $160 million of lease liabilities on our consolidated balance sheet and a cumulative-effect adjustment to stockholders'stockholders’ equity on the date of adoption of $31 million. As of March 31, 2019, we have approximately $254 million of lease liabilities and $247 million of ROU assets on our consolidated balance sheet related to long-term leases further discussed in Note 12. The increase in ROU assets and liabilities during the quarter is due to new contracts signed in the first quarter of 2019.$31 million. We continue presenting all prior comparative periods without any restatements.

Hedge accounting standard
In August 2017, the FASB issued a new accounting standards update that amends the hedge accounting model to enable entities to hedge certain financial and nonfinancial risk attributes previously not allowed. The amendment also reduces the overall complexity of documenting, assessing and measuring hedge effectiveness. This standard was effective for us in the first quarter of 2019. Adoption of this standard did not have a significant impact on our consolidated results of operations, financial position or cash flows.

The contract liability balance on January 1, 2019 primarily relates to the advance consideration received from customers for crude oil sales and processing services in the U.K. A contract asset would represent crude oil delivered in the U.K. to a customer for which payment will be collected over time as it becomes due under the pricing terms stipulated in the sales agreement. As a practical expedient, when the balance of this U.K. customer is a contract asset, we do not adjust revenue for the effects of a significant financing element as the period between when crude oil is deliveredSubsequent to the customer and when payment is expectedsale of our U.K. business, we no longer hold this contract liability.

7.    Segment Information
We have two2 reportable operating segments. Both of these segments are organized and managed based upon geographic location and the nature of the products and services offered.
United States ("(“U.S.") – explores for, produces and markets crude oil and condensate, NGLs and natural gas in the United States
International ("Int’l"(“Int’l”) – explores for, produces and markets crude oil and condensate, NGLs and natural gas outside of the United States andas well as produces and markets products manufactured from natural gas, such as LNG and methanol, in Equatorial Guinea (“E.G.”)
Information regarding assets by segment is not presented because it is not reviewed by the chief operating decision maker (“CODM”). Segment income represents income which excludes certain items not allocated to our operating segments, net of income taxes. A portion of our corporate and operations general and administrative support costs are not allocated to the operating segments. These unallocated costs primarily consist of employment costs (including pension effects), professional services, facilities and other costs associated with corporate and operations support activities. Additionally, items which affect comparability such as: gains or losses on dispositions, provedcertain property impairments, change in tax associated with a tax legislation change, unrealized gains or losses on commodity derivative instruments, pension settlement losses or other items (as determined by the CODM) are not allocated to operating segments.

7.8.    Income Taxes
Effective Tax Rate
The effective income tax rate is influenced by a variety of factors including the geographic and functional sources of income and the relative magnitude of these sources of income. The difference between the total provision and the sum of the amounts allocated to segments is reported in the “Not Allocated to Segments” column of the tables in Note 67.
For the three and nine months ended March 31,September 30, 2019 and 2018, our effective income tax rates were as follows:
 Three Months Ended March 31,
 2019 2018
Effective income tax expense (benefit) rate(a)
(544)% 32%
 Three Months Ended September 30, Nine Months Ended September 30,
 2019 2018 2019 2018
Effective income tax expense (benefit) rate(a)
6% 29% (27)% 31%

(a) 
In all periods presented, we maintained our valuation allowance on our net federal deferred tax assets in the U.S.
The following items caused the effective income tax rates to be different from our U.S. statutory tax rate of 21% for 2019 and 2018:
DuringIncome taxes for the threethird quarter of 2019 were impacted by the income mix between domestic and international operations. Income taxes for the nine months ended March 31,September 30, 2019 we settledwere impacted by the settlement of the 2010-2011 U.S. Federal Tax Audit ("(“IRS Audit"Audit”) in the first quarter of 2019, resulting in a tax benefit of $126 million. Additionally, in the first quarter of 2019, we recorded a non-cash deferred tax benefit of $18 million in the U.K. related to an internal restructuring. These two items are discrete to the first quarternine months of 2019. Excluding these discrete adjustments, the effective income tax rate for the quarterfirst nine months of 2019 was a benefitan expense of 8%10%.
Income taxes for the third quarter of 2018 were impacted by deferred tax expense in the U.K. During the threenine months ended March 31,September 30, 2018, we incurredincome taxes were impacted by the tax expense in Libya of $162 million. Excluding Libya, the effective income tax rate for the three months ended March 31, 2018, was an expense of 2%.

As a result of the IRS Audit settlement in the first quarter of 2019, the uncertain tax positions previously established are now effectively settled. The release of the accrued uncertain tax positions resulted in a $126 million tax benefit, primarily related to the additional alternative minimum tax (“AMT”) credits, see Note 2223 for further detail.

Pursuant to the Tax Sharing Agreement we entered into with Marathon Petroleum Corporation (“MPC”) in connection with the 2011 spin-off transaction, MPC agreed to indemnify us for certain liabilities. In addition to the benefit from the settlement of the IRS Audit in the first quarter of 2019, we recorded a current receivable and other income of $42 million for indemnity payments due from MPC for tax expense and interest we had previously recognized. The indemnity relates to tax and interest allocable to MPC as a result of the IRS Audit. During the second quarter of 2019, we paid the IRS and were subsequently reimbursed by MPC which settledfor settlement of their indemnity obligation.

During the three months ended March 31,first quarter of 2019, we withdrew our appeal related to the Brae area decommissioning costs in the U.K,U.K., thus the uncertain tax positions previously established are now considered effectively settled with no tax expense or benefit impact in the first quarter of 2019.

In determining our ROU assets and long-term lease liabilities, the new lease standard requires certain accounting policy decisions, while also providing a number of optional practical expedients for transition accounting. Our accounting policies and the practical expedients utilized are summarized below:
Implemented an accounting policy to not recognize any right-of-use assets and lease liabilities related to short-term leases on the balance sheet.
Implemented an accounting policy to not separate the lease and nonlease components for all asset classes, except for vessels.
Elected the package of practical expedients which allows us to not reassess our prior conclusions regarding the lease identification and lease classification for contracts that commenced or expired prior to the effective date.
MARATHON OIL CORPORATION
Notes to Consolidated Financial Statements (Unaudited)

Elected the practical expedient pertaining to land easements which allows us to continue accounting for existing agreements under the previous accounting policies as nonlease transactions. Any modifications of existing contracts or new agreements will be assessed under the new lease accounting guidance and may become leases in the future.
We enter into various lease agreements to support our operations including drilling rigs, well fracturing equipment, compressors, buildings, aircraft, vessels, vehicles and miscellaneous field equipment. We primarily act as a lessee in these transactions and all of our existing leases are classified as either short-term or long-term operating leases.
The majority of the drilling rig agreements and all of fracturing equipment agreements are classified as short-term leases based on the noncancellable period for which we have the right to use the equipment and assessment of options present in each agreement. We also incur variable lease costs under these agreements primarily related to chemicals and sand used in fracturing operations or various additional on-demand equipment and labor. The lease costs associated with the drilling rigs and fracturing equipment are primarily capitalized as part of the well costs.
Our long-term leases are comprised of compressors, buildings, drilling rigs, aircraft, vessels, vehicles and miscellaneous field equipment. Our lease agreements may require both fixed and variable payments; none of the variable payments are rate or index-based, therefore only fixed payments were considered for recognizing lease liabilities and ROU assets related to long-term leases. Also, based on our election not to separate the lease and nonlease components, fixed payments related to equipment, crew and other nonlease components are included in the initial measurement of lease liabilities and ROU assets for all asset classes, except for vessels. For vessels, the contractual consideration was allocated between lease and nonlease components based on estimates provided by service providers.
Our leased assets may be used in joint oil and gas operations with other working interest owners. We recognize lease liabilities and ROU assets only when we are the signatory to a contract as an operator of joint properties. Such lease liabilities and ROU assets are determined based on gross contractual obligations. As we use the leased assets for joint operations, we have the contractual right to recover the other working interest owners’ share of lease costs. As a result, our lease costs are presented on a net basis, reduced for any costs recoverable from other working interest owners. The table below presents our net lease costs as of March 31,September 30, 2019 with the majority of operating lease costs expensed as incurred, while the majority of the short-term and variable term lease costs are capitalized into property, plant and equipment.

In 2018, we signed an agreement with an owner/lessor to construct and lease a new build-to-suit office building in Houston, Texas. The new Houston office location is expected to be completed in 2021. The lessor and other participants are providing financing for up to $380 million, to fund the estimated project costs. As of March 31,September 30, 2019, project costs incurred totaled $47approximately $54 million, primarily for land acquisition and initial design costs. The initial lease term is five years and will commence once construction is substantially complete and the new Houston office is ready for occupancy. At the end of the initial lease term, we can negotiate to extend the lease term for an additional five years, subject to the approval of the participants; purchase the property subject to certain terms and conditions; or remarket the property to an unrelated third party. The lease contains a residual value guarantee of approximately 89% of the total acquisition and construction costs.

Commodity Derivatives
We have entered into multiple crude oil derivatives indexed to the respective indices as noted in the table below, related to a portion of our forecasted United States sales through 2021.2021. These derivatives consist of three-way collars, basis swaps and NYMEX roll basis swaps. Three-way collars consist of a sold call (ceiling), a purchased put (floor) and a sold put. The ceiling price is the maximum we will receive for the contract volumes; the floor is the minimum price we will receive, unless the market price falls below the sold put strike price. In this case, we receive the NYMEX WTI price plus the difference between the floor and the sold put price. These commoditycrude oil derivatives were not designated as hedges.

(a) 
Derivative instruments are recorded on a net basis in our consolidated balance sheet. See Note 1314.
Commodity derivatives include three-way collars, basis swaps and NYMEX roll basis swaps. These instruments are measured at fair value using either a Black-Scholes or a modified Black-Scholes Model. For basis swaps and NYMEX roll basis swaps, inputs to the models include only commodity prices and interest rates and are categorized as Level 1 because all assumptions and inputs are observable in active markets throughout the term of the instruments. For three-way collars, inputs to the models include commodity prices, and implied volatility and are categorized as Level 2 because predominantly all assumptions and inputs are observable in active markets throughout the term of the instruments.
The forward starting interest rate swaps are measured at fair value with a market approach using actionable broker quotes, which are Level 2 inputs. See Note 14 for detail on the forward starting interest rate swaps.

Fair Value Estimates - Goodwill
As of September 30, 2019, our consolidated balance sheet included goodwill of $95 million. Goodwill is tested for impairment on an annual basis, or between annual tests when events or changes in circumstances indicate the fair value may have been reduced below its carrying value. Goodwill is tested for impairment at the reporting unit level. Our reporting units are the same as our reporting segments, of which only the International reporting unit includes goodwill. Our policy is to first assess the qualitative factors in order to determine whether the fair value of our International reporting unit is more likely than not less than its carrying amount. Certain qualitative factors used in our evaluation include, among other things, the results of the most recent quantitative assessment of goodwill (second quarter of 2017); macroeconomic conditions; industry and market conditions (including commodity prices and cost factors); overall financial performance; and other relevant entity-specific events. If, after considering these events and circumstances we determine that it is more likely than not the fair value of the International reporting unit is less than its carrying amount, the quantitative goodwill test is performed.
During the second quarter of 2019, we performed our annual impairment test of goodwill using the qualitative assessment. Our qualitative assessment considered the significant excess fair value over carrying value in our most recent step one test and noted there are more positive/neutral indicators than negative. After assessing the totality of these qualitative factors, our assessment did not indicate that it is more likely than not that the fair value is less than its carrying value. As a result, we concluded that no impairment to goodwill was required for our International reporting unit.
Fair Values – Nonrecurring
See Note 4 and Note 10forFor detail on our fair values for nonrecurring items such assee Note 5 , for detail related to an outstanding guarantee related to our U.K. disposition and Note 11for detail related to impairments.
Fair Values – Financial Instruments
Our current assets and liabilities include financial instruments, the most significant of which are receivables, the current portion of our long-term debt and payables. We believe the carrying values of our receivables and payables approximate fair value. Our fair value assessment incorporates a variety of considerations, including (1) the short-term duration of the instruments, (2) our credit rating and (3) our historical incurrence of and expected future insignificant bad debt expense, which includes an evaluation of counterparty credit risk.

Fair values of our financial assets included in other noncurrent assets, and of our financial liabilities included in other current liabilities and deferred credits and other liabilities, are measured 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.
All of our long-term debt instruments are publicly traded. A market approach, based upon quotes from major financial institutions, which are Level 2 inputs, is used to measure the fair value of our debt.

Stock-based performance unit awards
During the first threenine months of 2019, we granted 656,636 stock-based performance units to certain officers to be settled in shares. The grant date fair value per unit was $20.66, as calculated using a Monte Carlo valuation model. At the grant date, each unit represents the value of one share of our common stock. These units are settled in shares, and the number of shares of our common stock to be paid is based on the vesting percentage, which can be from zero0 to 200% based on performance achieved over a three-year performance period ending December 31, 2021, and as determined by the Compensation Committee of the Board of Directors. The performance goals are tied to our total shareholder return (“TSR”) as compared to TSR for a group of peer companies determined by the Compensation Committee of our Board of Directors. Dividend equivalents may accrue during the performance period and would be paid in cash at the end of the performance period based on the amount of dividends credited generally over the performance period on shares of our common stock that represent the number of the units granted multiplied by the vesting percentage.

22.23.    Commitments and Contingencies
Following the sale of our U.K. business to RockRose, we continue to have surety bonds outstanding that guarantee our decommissioning liabilities related to the MOUK assets. We issued these surety bonds in November 2018 with a notional value of approximately £92 million and an expiration date of December 31, 2019. RockRose is contractually required to post a replacement security to cover 2020 by no later than December 1, 2019. If RockRose is unable to post a replacement security by December 1, 2019, the counterparties of our existing surety bonds have the right to submit a demand notice against our surety bonds. In order to mitigate this exposure, we have secured surety bonds from RockRose issued in favor of Marathon for the full amount of £92 million. As of September 30, 2019, RockRose had not posted a replacement security and we recognized a liability and corresponding expense of approximately $6 million related to the estimated fair value of our exposure to these surety bonds. Should RockRose post a replacement security, we will derecognize our $6 million other current liability and record income of a corresponding amount. See Note 5for discussion of the U.K. sale in further detail.
In the second quarter of 2019, Marathon E.G. Production Limited (“MEGPL”), a consolidated and wholly-owned subsidiary, signed a series of agreements to process third-party Alen Unit gas through existing infrastructure located in Punta Europa, E.G. MEGPL is a signatory to the agreements related to our equity method investee, Alba Plant LLC. These agreements contain clauses that cause MEGPL to indemnify the owners of the Alen Unit against actions or inaction by Alba Plant LLC. Pursuant to these agreements, MEGPL agreed to indemnify third party property or events, including environmental assessments, injury to Alba Plant LLC’s personnel, and damage to or loss of Alba Plant LLC’s automobiles. At this time, we cannot reasonably estimate this obligation as we do not have any history of prior indemnification claims, as completion of the plant modifications is not expected to finish until 2021, and as such, we do not have any history of environmental discharge or contamination. Therefore, we have not recorded a liability with respect to these indemnification clauses since the amount of potential future payments under such guarantees is not determinable.
In the fourth quarter of 2017, the U.K. tax authorities challenged the deductibility for certain Brae area decommissioning costs, which we claimed for U.K. corporation tax purposes. The dispute related to the timing of the deduction and did not dispute the general deductibility of decommissioning costs. In accordance with U.K. regulations, we paid the amount of tax and interest in question, approximately $108 million, prior toand filed our appeal. In the first quarter of 2019, we withdrew our appeal on this matter, and the corresponding revisions to current and deferred tax liabilities have no cumulative adverse earnings impact on our consolidated results of operations.
We are continuously undergoing examination of our U.S. federal income tax returns by the IRS. With the closure of the 2010-2011 IRS Audit referenced in Note 78, these audits have been completed through the 20142016 tax year with the exception of the partnership item discussed below.following item. During the third quarter of 2017, we received a partnership adjustment notification related to the 2010 and 2011 tax years, for which we have filed a Tax Court Petition in the fourth quarter of 2017. We believe that itDuring the third quarter of 2019, we received the court decision which ruled in our favor for all material items. The IRS is more likely than not that we will prevail.in the process of preparing the final reports for the 2010 and 2011 tax years.
MARATHON OIL CORPORATION
Notes to Consolidated Financial Statements (Unaudited)

We are a defendant in a number of legal and administrative proceedings arising in the ordinary course of business including, but not limited to, royalty claims, contract claims, tax disputes and environmental claims. While the ultimate outcome and impact to us cannot be predicted with certainty, we believe the resolution of these proceedings will not have a material adverse effect on our consolidated financial position, results of operations or cash flows. 
We have incurred and will continue to incur 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 offset by the prices we receive for 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 and production processes. These laws generally provide for control of pollutants released into the environment and require responsible parties to undertake remediation of hazardous waste disposal sites. Penalties may be imposed for noncompliance.
23.    Subsequent Event
On April 1, 2019, we signed a definitive agreement to process third-party Alen Unit gas through existing infrastructure located in Punta Europa, E.G. First gas sales from the Alen Unit is expected in 2021, and will utilize available processing capacity not required by the Alba Field. We are the operator and majority shareholder of the integrated gas business at Punta Europa and will maintain market exposure through a combination of both profit sharing and tolling.

Crude oil and condensate Alba Field liquids production is primarily condensate and generally sold in relation to the Brent crude benchmark. Alba Plant LLC processes the rich hydrocarbon gas which is supplied by the Alba Field under a fixed price long term contract. Alba Plant LLC extracts NGL’sNGLs and secondary condensate which is then sold by Alba Plant LLC at market prices, with our share of the revenue reflected in income from equity method investments on the consolidated statements of income. Alba Plant delivers the processed dry natural gas to the Alba Field for distribution and sale to AMPCO and EG LNG.
Natural gas liquids Wet gas is sold to Alba Plant LLC at a fixed-price term contract resulting in realized prices not fully tracking market price. Alba Plant LLC extracts and keeps NGLs, which are sold at market price, with our share of income from Alba Plant LLC being reflected in the income from equity method investments on the consolidated statements of income.
Natural gas Dry natural gas, processed by Alba Plant LLC on behalf of the Alba Field is sold by the Alba Field to EGHoldingsEG LNG and AMPCO at fixed-price long term contracts resulting in realized prices not fully tracking market price. We derive additional value from the equity investment in our downstream gas processing units EG LNG and AMPCO. EG LNG sells LNG on a market-based long-term contract and AMPCO that market LNG andmarkets methanol at market prices.

The DD&A rate (expense per boe), which is impacted by field-level changes in reserves, capitalized costs and sales volumes, can also impact our DD&A expense. Our International DD&A rate decreased primarily due to the sale of our U.K. business. Our United States DD&A rate decreased primarily due to non-core asset dispositions in the Gulf of Mexico in the third quarter 2018 and first quarterhalf 2019.

Net loss on commodity derivatives In the first threenine months of 2019, the net loss on commodity derivatives was $28 million, compared to the same period in 2018 which was a loss of $324 million. We have multiple crude oil derivative contracts that settle against various indices. We record commodity derivative gains/losses as the index pricing and forward curves change each period. See Note 14 to the consolidated financial statements for further information.
Income from equity method investmentsdecreased $98 million for the first nine months of 2019 due to the triennial turnaround in E.G. and natural field decline of the Alba field, which resulted in lower net sales volumes for equity method investments in E.G.
Net gain on disposal of assetsdecreased $267 million for the first nine months of 2019 primarily as a result of the sale of our Libya subsidiary for a pre-tax gain of $255 million in the first quarter of 2018. See Note 5 to the consolidated financial statements for information about dispositions.
Other incomedecreased $81 million in the first nine months of 2019 primarily as a result of the 2018 reduction of our U.K. asset retirement obligation, versus the 2019 indemnification of certain tax liabilities in connection with the closure of the 2010-2011 Federal Tax Audit with the IRS. This indemnity relates to tax and interest allocable to MPC as a result of the IRS Audit in accordance with the Tax Sharing Agreement. See Note 8 for further detail.
Production expenses for the first nine months of 2019 decreased by $94 million compared to the same period in 2018. International decreased $50 million primarily as a result of dispositions, partially offset by an increase due to the planned triennial turnaround in E.G. during the first quarter of 2019. United States decreased $43 million primarily due to reduced water hauling costs with more water on pipe in the Northern Delaware, and non-core asset dispositions in the Gulf of Mexico during the third quarter 2018, slightly offset by increased net sales volumes.
The first nine months of 2019 production expense rate (expense per boe) was lower for our United States segment due to continued focus on cost reduction as well as higher net sales volumes in 2019. Expense per boe for our International segment decreased due to dispositions (above).

Disposals of assets for the first nine months of 2019 were primarily related to proceeds, net of the cash transferred to the buyer, with the sale of our U.K. business; partially offset by the proceeds received from the sale of our 25% non-operating working interest in the Louisiana Austin Chalk as well as from the sale of our non-operated interest in the Atrush block in Kurdistan. Proceeds from the disposals of assets for the first threenine months of 2018 were primarily related to the final proceeds received from the sale of our Canadian business and sale of our non-operated interest in Libya. See Note 45 to the consolidated financial statements for further information concerning dispositions.

Liquidity and Capital Resources
Available Liquidity
In September 2019, we entered into an amendment to our Credit Facility to reduce the maximum borrowing from $3.4 billion to $3.0 billion and extended the maturity date by one year to May 28, 2023.
Our main sources of liquidity are cash and cash equivalents, internally generated cash flow from operations, sales of non-core assets, capital market transactions, and our revolving Credit Facility. At March 31,September 30, 2019, we had approximately $4.4$4.2 billion of liquidity consisting of $1.0$1.2 billion in cash and cash equivalents and $3.4$3.0 billion available under our revolving Credit Facility. Our working capital requirements are supported by these sources and we may issue either commercial paper backed by our Credit Facility or draw on our revolving Credit Facility to meet short-term cash requirements, or issue debt or equity securities through the shelf registration statement discussed below as part of our longer-term liquidity and capital management program. Because of the alternatives available to us as discussed above, we believe that our short-term and long-term liquidity are adequate to fund not only our current operations, but also our near-term and long-term funding requirements including our capital spending programs, dividend payments, defined benefit plan contributions, repayment of debt maturities, and other amounts that may ultimately be paid in connection with contingencies.
General economic conditions, commodity prices, and financial, business and other factors could affect our operations and our ability to access the capital markets. Our corporate credit ratings as of March 31,September 30, 2019are: Standard & Poor'sPoor’s Ratings Services BBB- (positive)BBB (stable); Fitch Ratings BBB (stable); and Moody's Investor Services, Inc. Ba1 (positive). On April 24, 2019, Moody’s Investor Services, Inc. upgraded ourBaa3 (stable). We are rated investment grade at all three primary credit rating to Baa3 (stable). As a result of the recent upgrade to an investment grade credit rating,agencies. In addition, we also have the ability to borrow on our U.S. commercial paper


program, which is backed by the revolving credit facility.Credit Facility. A downgrade in our credit ratings could increase our future cost of financing or limit our ability to access capital, and could result in additional collateralcredit support requirements. See Item 1A. Risk Factors in our Annual Report on Form 10-K for the year ended December 31, 2018 for a discussion of how a further downgrade in our credit ratings could affect us.
Capital Resources
Credit Arrangements and Borrowings
At March 31,September 30, 2019, we had no borrowings against our revolving credit facility.Credit Facility or under our U.S. commercial paper program that is backed by the Credit Facility.
At March 31,September 30, 2019, we had $5.5 billion in long-termof total debt outstanding, withincluding $600 million due June 2020. On October 3, 2019, we redeemed our $600 million 2.7% senior unsecured notes due June 2020. After considering this debt redemption, our next debt maturity inis the amount of $600 million$1.0 billion 2.8% senior unsecured notes due in June 2020.2022. We do not have any triggers on any of our corporate debt that would cause an event of default in the case of a downgrade of our credit ratings.
On October 1, 2019, we closed a $600 million remarketing to investors of sub-series A bonds which are part of the $1.0 billion St. John the Baptist, State of Louisiana revenue refunding bonds originally issued and purchased in December 2017. The $600 million in proceeds from the conversion and remarketing were used to pay the purchase price of our converted 2017 bonds on the closing date. We continue to own the remaining $400 million of the revenue refunding bonds and have the right to convert and remarket them to investors at any time up to the 2037 maturity date.
Shelf Registration
We have a universal shelf registration statement filed with the SEC under which we, as a "well-known“well-known seasoned issuer"issuer” for purposes of SEC rules, have the ability to issue and sell an indeterminate amount of various types of debt and equity securities. 
Asset Disposal
In the first quarter ofOn July 1, 2019, we entered into an agreement to sellclosed on the sale of our U.K. business. Subject to customary adjustments, the closing consideration payable to us will bebusiness for proceeds of approximately $140$95 million, which reflectsreflecting the assumption by the buyer of the MOUKworking capital and MOWOS cash equivalent balance and working capital balance, which was approximately $350balances, asset retirement obligations of $966 million, at December 31, 2018. Though there are certain contractual requirements that must be satisfied,as well as the transaction is expected to close inpension obligations.
In the second halfquarter of 2019, with an effective datewe closed on the sale of January 1, 2019.
We entered into an agreement to sell our subsidiary, Marathon Oil KDV B.V., which holds our 15% non-operated interest in the Atrush block in Kurdistan for proceeds of $63 million, before closing adjustments. We expect this transaction to close in the second quarter of 2019. See Note 45 to the consolidated financial statements for further information concerning dispositions.
Debt-To-Capital Ratio
The Credit Facility includes a covenant requiring that our debt-to-capital ratio of total debt to total capitalization not exceed 65% as of the last day of the fiscal quarter. Our debt-to-capital ratio was 31% at March 31,September 30, 2019 and at December 31, 2018.
Capital Requirements
Share Repurchase Program
In the nine months ended September 30, 2019, we acquired approximately 19 million common shares at a cost of $280 million under our share repurchase program with remaining share repurchase authorization is $1.5 billion.
Other Expected Cash Outflows
On April 24,October 30, 2019, our Board of Directors approved a dividend of $0.05 per share for the firstthird quarter of 2019 payable JuneDecember 10, 2019 to stockholders of record at the close of business on May 15,November 20, 2019.
As of March 31,September 30, 2019, we plan to make contributions of up to $32$6 million to our funded pension plans during the remainder of 2019.


Contractual Cash Obligations
AsIn the first quarter of March 31, 2019, we have entered into various transportation and processing commitments to guarantee capacity on crude oil and natural gas pipelines and natural gas processing facilities, which have varying terms extending as far as 2027. Future commitments remaining as of March 31,September 30, 2019 under the arrangements amount to $571$559 million, of which $17$5 million is expected to be incurred in the remainder of 2019, $54 million in 2020, $75 million in 2021, $76 million in 2022, $78 million in 2023, and $271 million thereafter.



Environmental Matters and Other Contingencies
We have incurred and will continue to incur 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 offset by the prices we receive for 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 and production processes. These laws generally provide for control of pollutants released into the environment and require responsible parties to undertake remediation of hazardous waste disposal sites. Penalties may be imposed for noncompliance.
There have been no significant changes to the environmental, health and safety matters under Item 1. Business or Item 3. Legal Proceedings in our 2018 Annual Report on Form 10-K. See Note 2223 to the consolidated financial statements for a description of other contingencies.

We employ various strategies, including the use of financial derivatives to manage the risks related to commodity price fluctuations. See Note 1314 and Note 1415 to the consolidated financial statements for detail relating to our open commodity derivative positions, including underlying notional quantities, how they are reported in our consolidated financial statements and how their fair values are measured.

As of March 31,September 30, 2019, we had various open commodity derivatives related to crude oil with a net asset position of $14$58 million. Based on the March 31,September 30, 2019 published index prices, a hypothetical 10% change (per bbl for crude oil) increases (decreases) the fair values of our net commodity derivative open positions as follows:
(In millions)Hypothetical Price Increase of 10% Hypothetical Price Decrease of 10%Hypothetical Price Increase of 10% Hypothetical Price Decrease of 10%
Crude oil derivatives$(30) $30
$(50) $45

Interest Rate Risk
At March 31,September 30, 2019 our portfolio of current and long-term debt is comprised of fixed-rate instruments with an outstanding balance of $5.5 billion. Our sensitivity to interest rate movements and corresponding changes in the fair value of our fixed-rate debt portfolio affects our results of operations and cash flows only when we elect to repurchase or otherwise retire fixed-rate debt at prices different than carrying value.
Item 4. Controls and Procedures
An evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) was carried out under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer.  As of the end of the period covered by this Report 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 March 31,September 30, 2019.  
During the first three months ofended September 30, 2019, 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.
