Basis of Presentation |
6 Months Ended |
|---|---|
Jun. 30, 2019 | |
| Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
| Basis of Presentation | Basis of Presentation Presentation. In the opinion of management, the unaudited interim consolidated financial statements of the Company as of June 30, 2019 and for the three and six months ended June 30, 2019 and 2018 include all adjustments and accruals, consisting only of normal, recurring adjustments and accruals necessary for a fair presentation of the results for the interim periods in conformity with generally accepted accounting principles in the United States ("GAAP"). The operating results for the three and six months ended June 30, 2019 are not necessarily indicative of results for a full year. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted in accordance with the rules and regulations of the United States Securities and Exchange Commission (the "SEC"). These unaudited interim consolidated financial statements should be read together with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2018. Certain reclassifications have been made to prior period amounts to conform to the current period's presentation. Use of estimates in the preparation of financial statements. Preparation of the Company's unaudited interim consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Depletion of oil and gas properties and evaluations for impairment of goodwill and proved and unproved oil and gas properties, in part, is determined using estimates of proved, probable and possible oil and gas reserves. There are numerous uncertainties inherent in the estimation of quantities of proved, probable and possible reserves and in the projection of future rates of production and the timing of development expenditures. Similarly, evaluations for impairment of proved and unproved oil and gas properties are subject to numerous uncertainties including, among others, estimates of future recoverable reserves and commodity price outlooks. Actual results could differ from the estimates and assumptions utilized. Adoption of new accounting standards. In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-02, "Leases (Topic 842)" ("ASC 842"), which supersedes the lease recognition requirements in Accounting Standards Codification ("ASC") 840, "Leases" ("ASC 840"), and requires lessees to recognize lease assets and lease liabilities for those leases previously classified as operating leases. The Company adopted ASC 842 as of January 1, 2019 using the modified retrospective transition method. The Company elected to apply the transition guidance under ASU 2018-11, "Leases (Topic 842) Targeted Improvements," in which ASC 842 is applied at the adoption date, while the comparative periods continue to be reported in accordance with historic accounting under ASC 840. This standard does not apply to leases to explore for or use minerals, oil or gas resources, including the right to explore for those natural resources and rights to use the land in which those natural resources are contained. ASC 842 allowed for the election of certain practical expedients at adoption to ease the burden of implementation. At implementation, the Company elected to (i) maintain the historical lease classification for leases prior to January 1, 2019, (ii) maintain the historical accounting treatment for land easements that existed at adoption, (iii) use historical practices in assessing the lease term of existing contracts at adoption, (iv) combine lease and non-lease components of a contract as a single lease and (v) not record short-term leases on the consolidated balance sheet, all in accordance with ASC 842. The adoption of ASC 842 did not have a material impact on the consolidated statements of operations and had no impact on the Company's cash flows. The Company did not record a change to its opening retained earnings as of January 1, 2019, as there was no material change to the timing or pattern of recognition of lease costs due to the adoption of ASC 842. As of December 31, 2018, the Company was the deemed owner of the Company's new corporate headquarters (for accounting purposes) during the construction period and was following the build-to-suit accounting guidance under ASC 840. On January 1, 2019, upon the adoption of ASC 842, the Company derecognized $217 million of other property and equipment and $219 million of build-to-suit lease liability costs associated with the building as this contract no longer qualifies for capitalization. The contract will be evaluated and recorded on the consolidated balance sheets upon lease commencement, which is expected to occur during the second half of 2019. New accounting pronouncements. In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments" ("ASU 2016-13"). ASU 2016-13 changes the impairment model for most financial assets and certain other instruments, including trade and other receivables, and requires entities to use a new forward-looking expected loss model that will result in the earlier recognition of allowances for losses. This update is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted. Entities will use the modified retrospective approach to apply the standard's provisions and record a cumulative-effect adjustment to retained earnings for the any additional receivable loss allowances, if any, as of the beginning of the first reporting period in which the guidance is adopted. The Company continues to evaluate ASU 2016-13, but does not expect that it will have a material impact on its consolidated financial statements.

Contingent Consideration. The Company is entitled to receive contingent consideration of up to $450 million based on future annual oil and NGL prices during each of the years from 2020 to 2024. The Company used an option pricing model to determine the fair value of the contingent consideration as of the date of the sale, which resulted in an estimated fair value of $136 million. The fair value of the contingent consideration is classified as noncurrent other assets in the consolidated balance sheets. The Company will revalue the contingent consideration each reporting period, with any valuation changes being recorded as net interest and other income (loss) in the consolidated statements of operations for such period. See Note 4 and Note 5 for additional information. Deficiency Fee Obligation and Receivable. The Company transferred its long-term midstream agreements and associated minimum volume commitments (“MVC”) to the buyer. However, the Company retained the obligation to pay 100 percent of any deficiency fees associated with the MVC's from January 2019 through July 2022. The buyer is required to reimburse the Company for up to 20 percent of the deficiency fees paid from January 2019 through July 2022. Such reimbursement will be paid by the buyer in installments beginning in 2023 through 2025. The Company classified $106 million as other current liabilities and $242 million as other noncurrent liabilities as of the date of the sale, which represents the probability weighted present value of the estimated future deficiency fee obligation. The Company utilized a credit risk-adjusted valuation model to determine the present value of the estimated deficiency fee receivable of $72 million attributable to future deficiency fees that will be reimbursed by the buyer as of the date of the sale. The deficiency fee receivable is classified as noncurrent other assets in the consolidated balance sheet. Changes to the deficiency fee obligation and receivable are expected to primarily result from accretion over the term of the arrangements; however, adjustments could also result from changes in the buyer's development plan and future drilling and production results. Restricted Cash. As of the date of the sale, the Company deposited $75 million into an escrow account to be used to fund future deficiency fee payments. Accordingly, the $75 million is classified as restricted cash in the consolidated balance sheet as of June 30, 2019. Beginning in 2021, the required escrow balance will decline to $50 million and, to the extent that there is any remaining balance after the payment of deficiency fees, the balance will become unrestricted and revert to the Company on March 31, 2023.
Decommissioning In November 2018, the Company announced plans to close its sand mine located in Brady, Texas and transition its proppant supply requirements to West Texas sand sources. During the six months ended June 30, 2019, the Company recorded $23 million of accelerated depreciation and $17 million of inventory and other property and equipment impairment charges associated with the sand mine closure. Restructuring During the six months ended June 30, 2019, the Company implemented a corporate restructuring program to align its cost structure with the needs of a Permian Basin-focused company. The restructuring occurred in three phases (collectively, the "Corporate Restructuring Program") as follows:
During the three and six months ended June 30, 2019, the Company recorded $146 million and $158 million, respectively, of employee-related charges associated with the Corporate Restructuring Program. See Note 15 for additional information. The employee-related costs are primarily recorded as other expense in the consolidated statements of operations. Obligations associated with employee-related charges are classified as accounts payable - due to affiliates in the consolidated balance sheets. The changes in the Company's total employee-related obligations are as follows:

| Fair Value Measurements | Fair Value Measurements The Company determines fair value based on the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements are based upon inputs that market participants use in pricing an asset or liability, which are characterized according to a hierarchy that prioritizes those inputs based on the degree to which they are observable. Observable inputs represent market data obtained from independent sources, whereas unobservable inputs reflect a company's own market assumptions, which are used if observable inputs are not reasonably available without undue cost and effort. The fair value input hierarchy level to which an asset or liability measurement in its entirety falls is determined based on the lowest level input that is significant to the measurement in its entirety. The three input levels of the fair value hierarchy are as follows:
Assets and liabilities measured at fair value on a recurring basis. Assets and liabilities measured at fair value on a recurring basis are as follows:
Commodity price derivatives. The Company's commodity price derivatives represent oil, NGL and gas swap contracts, collar contracts, collar contracts with short puts and basis swap contracts. The asset and liability measurements for the Company's commodity price derivative contracts are determined using Level 2 inputs. The Company utilizes discounted cash flow and option-pricing models for valuing its commodity price derivatives. The asset and liability values attributable to the Company's commodity price derivatives were determined based on inputs that include (i) the contracted notional volumes, (ii) independent active market price quotes, (iii) the applicable estimated credit-adjusted risk-free rate yield curve and (iv) the implied rate of volatility inherent in the collar contracts and collar contracts with short puts, which is based on active and independent market-quoted volatility factors. Deferred compensation plan assets. The Company's deferred compensation plan assets include investments in equity and mutual fund securities that are actively traded on major exchanges. The fair values of these investments are determined using Level 1 inputs based on observable prices on major exchanges. Investment in affiliate. The Company elected the fair value option for measuring its equity method investment in ProPetro. The fair value of its investment in ProPetro is determined using Level 1 inputs based on observable prices on a major exchange. Prior to June 30, 2019, the fair value of the Company's investment in ProPetro was determined using Level 2 inputs, including the quoted market price for the stock as adjusted to reflect a discount due to restrictions on the Company's ability to sell prior to July 1, 2019. See Note 12 and Note 14 for additional information. Divestiture contingent consideration. In May 2019, the Company completed the South Texas Divestiture and is entitled to receive contingent consideration of up to $450 million based on future oil and NGL prices during each of the years from 2020 to 2024. The Company uses an option pricing model to estimate the fair value of the contingent consideration using significant Level 2 inputs that include quoted future commodity prices based on active markets, implied volatility factors and counterparty credit risk assessments. See Note 3 and Note 5 for additional information. Assets and liabilities measured at fair value on a nonrecurring basis. Certain assets and liabilities are measured at fair value on a nonrecurring basis. These assets and liabilities are not measured at fair value on an ongoing basis, but are subject to fair value adjustments in certain circumstances. These assets and liabilities can include inventory, proved and unproved oil and gas properties and other long-lived assets that are written down to fair value when they are impaired or held for sale. Other assets. During the six months ended June 30, 2019, the Company impaired the remaining $17 million of inventory and other property and equipment related to the decommissioning of the Company's Brady, Texas sand mine, as these assets had no remaining future economic value. In addition, the Company recognized a $16 million impairment charge related to pressure pumping assets excluded from the December 2018 sale of the Company's pumping services assets. See Note 15 for additional information. South Texas Divestiture. In May 2019, the Company recorded an estimated deficiency fee obligation of $348 million and related estimated deficiency fee receivable of $72 million attributable to the South Texas Divestiture. The fair value of the deficiency fee obligation and deficiency fee receivable was determined using Level 3 inputs. The Company's estimates are based on a probability-weighted forecast that considers historical results, market conditions and various development plans to arrive at the estimated present value of the deficiency payments that will be required to be paid by the Company and the corresponding receivable that will be due from the buyer. The present value of the future cash payments and expected cash receipts were determined using a 2.9 percent and 3.2 percent discount rate, respectively, based on the timing of future payments and receipts and the Company's counterparty credit risk assessments. See Note 3 and Note 11 for additional information. Sale of Raton Basin assets. In June 2018, the Company recognized impairment charges of $77 million to reduce the carrying value of its Raton Basin gas field assets to the agreed upon sales price for these assets, which were sold in July 2018. The impairment charges included $65 million attributable to proved oil and gas properties and $12 million attributable to other property and equipment. The impairment charges were recorded as impairment of oil and gas properties in the consolidated statement of operations. The Company also recorded contract termination charges of $111 million attributable to estimated deficiency fees related to certain firm transportation contracts retained by the Company. The fair value of these contracts was determined using Level 2 inputs, including an annual discount rate of 4.4 percent, to discount the expected future cash flows. See Note 3 and Note 11 for additional information. Financial instruments not carried at fair value. Carrying values and fair values of financial instruments that are not carried at fair value in the consolidated balance sheets are as follows:
______________________
The Company has other financial instruments consisting primarily of receivables, payables, operating leases and other current assets and liabilities that approximate fair value due to the nature of the instrument and their relatively short maturities. Non-financial assets and liabilities initially measured at fair value include assets acquired and liabilities assumed in a business combination, goodwill and asset retirement obligations.

| Derivative Financial Instruments | Derivative Financial Instruments The Company utilizes commodity swap contracts, option contracts, collar contracts, collar contracts with short puts and basis swap contracts to (i) reduce the effect of price volatility on the commodities the Company produces and sells or consumes, (ii) support the Company's annual capital budgeting and expenditure plans and (iii) reduce commodity price risk associated with certain capital projects. The Company also, from time to time, utilizes interest rate contracts to reduce the effect of interest rate volatility on the Company's indebtedness. Oil production derivatives. The Company sells its oil production at the lease and the sales contracts governing such oil production are tied directly to, or are highly correlated with, New York Mercantile Exchange ("NYMEX") West Texas Intermediate ("WTI") oil prices. The Company also enters into pipeline capacity commitments in order to secure available oil transportation capacity from its areas of production to the Gulf Coast. In order to diversify the oil price it receives, the Company (i) enters into oil purchase transactions with third parties in its areas of production that are consistent with the oil prices that the Company receives at the lease, adjusted for transportation costs to the point of purchase, (ii) transports the purchased oil using its pipeline capacity to the Gulf Coast and (iii) enters into third party sale transactions to sell the oil into the Gulf Coast refinery or international export markets at prices that are highly correlated with Brent oil prices. As a result, the Company will generally use Brent derivative contracts to manage future oil price volatility. Volumes per day associated with the Company's outstanding oil derivative contracts as of June 30, 2019 and the weighted average oil prices for those contracts are as follows:
NGL production derivatives. All material physical sales contracts governing the Company's NGL production are tied directly or indirectly to Mont Belvieu, Texas NGL component product prices. The Company uses derivative contracts to manage the NGL component product price volatility. As of June 30, 2019, the Company did not have any NGL derivative contracts outstanding. Gas production derivatives. All material physical sales contracts governing the Company's gas production are tied directly or indirectly to NYMEX Henry Hub ("HH") gas prices or regional index prices where the gas is sold. The Company uses derivative contracts to manage gas price volatility and basis swap contracts to reduce basis risk between HH prices and actual index prices at which the gas is sold. Volumes per day associated with outstanding gas derivative contracts and the weighted average gas prices for those contracts are as follows:
____________________
Divestiture contingent consideration. The Company's right to receive contingent consideration in conjunction with the South Texas Divestiture was determined to be a derivative financial instrument that is not designated as a hedging instrument. The contingent consideration of up to $450 million is based on oil and NGL prices during each of the years from 2020 to 2024. See Note 3 and Note 4 for additional information. The Company's derivatives are accounted for as non-hedge derivatives and therefore all changes in the fair values of its derivative contracts are recognized as gains or losses in the earnings of the periods in which they occur. The Company enters into commodity price derivatives under master netting arrangements, which, in an event of default, allows the Company to offset payables to and receivables from the defaulting counterparty. Gains and losses associated with the Company's commodity price derivatives are separately presented on the consolidated statements of cash flows. Gains and losses associated with the Company's divestiture contingent consideration are presented as other noncash operating activities on the consolidated statements of cash flows. Fair value. The fair value of derivative financial instruments not designated as hedging instruments is as follows:
Gains and losses on derivative contracts are as follows:
The Company uses credit and other financial criteria to evaluate the credit standing of, and to select, counterparties to its derivative instruments. Although the Company does not obtain collateral or otherwise secure the fair value of its derivative instruments, associated credit risk is mitigated by the Company's credit risk policies and procedures.

| Leases | Leases The Company leases drilling rigs, storage tanks, equipment and office facilities under operating leases and recognizes lease expense on a straight-line basis over the lease term. Operating lease right-of-use assets and liabilities are initially recorded at commencement date based on the present value of lease payments over the lease term. As most of the Company's lease contracts do not provide an implicit discount rate, the Company uses its incremental borrowing rate, based on the information available at the commencement date of a lease. As of June 30, 2019, the weighted-average discount rate used in determining the present value of lease payments was 3.3 percent. Certain leases contain variable costs above the minimum required payments and are not included in the right-of-use assets or liabilities. Leases may include renewal, purchase or termination options that can extend or shorten the term of the lease. The exercise of those options is at the Company’s sole discretion and is evaluated at inception and throughout the contract to determine if a modification of the lease term is required. Leases with an initial term of 12 months or less are not recorded on the balance sheet. As of June 30, 2019, the weighted-average remaining lease term of the Company’s operating leases is 3.3 years. In June 2017, the Company entered into a 20-year operating lease for the Company's new corporate headquarters that is currently being constructed in Irving, Texas. Annual base rent is expected to be $33 million and lease payments are expected to commence once the building is complete. The Company has a variable equity interest in the entity that is constructing the building that is not considered material. The Company is not the primary beneficiary of the variable interest entity and only has a profit sharing interest after certain economic returns are achieved. The Company has no exposure to the variable interest entity's losses or future liabilities, if any. The contract for the Company's new corporate headquarters will be evaluated under ASC 842 upon lease commencement, which is expected to occur during the second half of 2019. The components of lease costs, including amounts recoverable from joint operating partners, are as follows:
______________________

| Commitments and Contingencies Disclosure [Abstract] | |||||||||||||||||||||||||||||||||||||
| Commitments and Contingencies | Commitments and Contingencies Legal actions. The Company is a party to various proceedings and claims incidental to its business. While many of these matters involve inherent uncertainty, the Company believes that the amount of the liability, if any, ultimately incurred with respect to these proceedings and claims will not have a material adverse effect on the Company's consolidated financial position as a whole or on its liquidity, capital resources or future annual results of operations. The Company records reserves for contingencies when information available indicates that a loss is probable and the amount of the loss can be reasonably estimated. Firm purchase, gathering, processing, transportation and fractionation commitments. From time to time, the Company enters into, and as of June 30, 2019 was a party to, take-or-pay agreements, which include contractual commitments (i) to purchase and process sand and purchase water for use in the Company's drilling operations, (ii) with midstream service companies and pipeline carriers for future gathering, processing, transportation, storage and fractionation services and (iii) with oilfield services companies that provide pressure pumping services. These commitments are normal and customary for the Company's business activities. Obligations following divestitures. In connection with its divestiture transactions, the Company may retain certain liabilities and provide the purchaser certain indemnifications, subject to defined limitations, which may apply to identified pre-closing matters, including matters of litigation, environmental contingencies, royalty and income taxes. Also associated with its divestiture transactions, the Company has issued and received guarantees to facilitate the transfer of contractual obligations, such as firm transportation agreements or gathering and processing arrangements. The Company does not recognize a liability if the fair value of the obligation is immaterial and the likelihood of making or receiving payments under these guarantees is remote. South Texas Divestiture. In conjunction with the South Texas Divestiture, the Company transferred its long-term midstream agreements and associated MVC's to the buyer. However, the Company retained the obligation to pay 100 percent of any deficiency fees associated with the MVC's from January 2019 through July 2022. The buyer is required to reimburse the Company for up to 20 percent of the deficiency fees paid by the Company from January 2019 through July 2022; such reimbursement will be paid by the buyer in installments beginning in 2023 through 2025. Assuming 100 percent of the MVC's are paid as deficiency fees, the maximum amount of future payments for this obligation would be approximately $650 million as of June 30, 2019. The Company's estimated deficiency fee obligation as of June 30, 2019 is $396 million, of which $154 million is classified as other current liabilities in the consolidated balance sheet, including $48 million of accrued deficiency fees from January 2019 through April 2019. The corresponding estimated deficiency fee receivable from the buyer of $66 million is classified as noncurrent other assets in the consolidated balance sheet as of June 30, 2019. The Company has received credit support for the deficiency fee receivable and the divestiture contingent consideration of up to $325 million. Raton transportation commitments. In July 2018, the Company completed the sale of its gas field assets in the Raton Basin to an unaffiliated third party and transferred certain gas transportation commitments, which extend through 2032, to the buyer for which the Company has provided a guarantee. Assuming 100 percent of the remaining commitments are paid by the Company under its guarantee, the maximum amount of future payments would be approximately $95 million as of June 30, 2019. The Company has received credit support for the commitments of up to $50 million. West Eagle Ford Shale commitments. In April 2018, the Company completed the sale of its West Eagle Ford Shale gas and liquids field to an unaffiliated third party and transferred certain gas and liquids transportation commitments, which extend through 2022, to the buyer for which the Company has provided a guarantee. Assuming 100 percent of the remaining commitments are paid by the Company under its guarantee, the maximum amount of future payments would be approximately $27 million as of June 30, 2019. The Company has received credit support for the commitments of up to $19 million. Certain contractual obligations were retained by the Company after the South Texas Divestiture, the divestiture of the Company's gas field assets in the Raton Basin and pressure pumping assets, and the decommissioning of the Company's sand mine operations in Brady, Texas. These contracts were primarily related to firm transportation and storage agreements in which the Company is unlikely to realize any benefit. The estimated obligations are classified as other current or noncurrent liabilities on the consolidated balance sheets. The changes in contract obligations are as follows:
______________________ (a) Additions include a $348 million of deficiency fee obligation related to the South Texas Divestiture, $48 million of accrued deficiency fees from January 2019 through April 2019 and $1 million related to sand mine decommissioning.

| Revenue from Contract with Customer [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Revenue Recognition | Revenue Recognition The Company recognizes revenue when control of the promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Disaggregated revenue from contracts with purchasers. Revenues on sales of oil, NGL, gas and purchased oil and gas are recognized when control of the product is transferred to the purchaser and payment can be reasonably assured. Sales prices for oil, NGL and gas production are negotiated based on factors normally considered in the industry, such as an index or spot price, distance from the well to the pipeline or market, commodity quality and prevailing supply and demand conditions. As such, the prices of oil, NGL and gas generally fluctuate based on the relevant market index rates. Disaggregated revenue from contracts with purchasers by product type is as follows:
Oil sales. Sales under the Company's oil contracts are generally considered performed when the Company sells oil production at the wellhead and receives an agreed-upon index price, net of any price differentials. The Company recognizes revenue when control transfers to the purchaser at the wellhead based on the net price received. NGL and gas sales. The Company evaluated whether it is the principal or the agent in gas processing transactions and concluded that it is the principal when it has the ability to take-in-kind, which is the case in the majority of the Company's gas processing and transportation contracts. Therefore the Company recognizes revenue on a gross basis, with the gathering, processing, transportation and fractionation costs associated with its take-in-kind arrangements being recorded as oil and gas production costs in the consolidated statement of operations. Sales of purchased oil and gas. The Company enters into pipeline capacity commitments in order to secure available oil, NGL and gas transportation capacity from the Company's areas of production. The Company enters into purchase transactions with third parties and separate sale transactions with third parties to (i) diversify a portion of the Company's WTI oil sales to the Gulf Coast refinery or international export markets and (ii) satisfy unused pipeline capacity commitments. Revenues and expenses from these transactions are presented on a gross basis as the Company acts as a principal in the transaction by assuming control of the commodities purchased and the responsibility to deliver the commodities sold. Revenue is recognized when control transfers to the purchaser at the delivery point based on the price received from the purchaser. The transportation costs associated with these transactions are presented as a component of purchased oil and gas expense. Firm transportation payments on excess pipeline capacity are recorded as other expense in the consolidated statements of operations. Performance obligations and contract balances. The majority of the Company's product sale commitments are short-term in nature with a contract term of one year or less. The Company typically satisfies its performance obligations upon transfer of control as described above in Disaggregated revenue from contracts with purchasers and records the related revenue in the month production is delivered to the purchaser. Settlement statements for sales of oil, NGL and gas and sales of purchased oil and gas may not be received for 30 to 60 days after the date the volumes are delivered, and as a result, the Company is required to estimate the amount of volumes delivered to the purchaser and the price that will be received for the sale of the product. The Company records the differences between estimates and the actual amounts received for product sales in the month that payment is received from the purchaser. Historically, differences between the Company's revenue estimates and the actual revenue received have not been significant. As of June 30, 2019 and December 31, 2018, the accounts receivable balance representing amounts due or billable under the terms of contracts with purchasers was $743 million and $646 million, respectively.
