Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business and Basis of Presentation	Description of Business and Basis of Presentation Organization and Nature of Operations Magnolia Oil & Gas Corporation (the “Company” or “Magnolia”) is an independent oil and natural gas company engaged in the acquisition, development, exploration, and production of oil, natural gas, and natural gas liquid (“NGL”) reserves. The Company’s oil and natural gas properties are located primarily in Karnes County and the Giddings Field in South Texas where the Company targets the Eagle Ford Shale and Austin Chalk formations. Magnolia’s objective is to generate stock market value over the long term through consistent organic production growth, high full cycle operating margins, an efficient capital program with short economic paybacks, significant free cash flow after capital expenditures, and effective reinvestment of free cash flow. Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial reporting. Accordingly, certain disclosures normally included in an Annual Report on Form 10-K have been omitted. The consolidated financial statements and related notes included in this Quarterly Report should be read in conjunction with the Company’s consolidated and combined financial statements and related notes included in the Company’s Annual Report on Form 10-K for the period ended December 31, 2019. Except as disclosed herein, there have been no material changes to the information disclosed in the notes to the consolidated and combined financial statements included in the Company’s Annual Report on Form 10-K for the period ended December 31, 2019. In the opinion of management, all normal, recurring adjustments and accruals considered necessary to present fairly, in all material respects, the Company’s interim financial results, have been included. Operating results for the periods presented are not necessarily indicative of expected results for the full year. Certain reclassifications of prior period financial statements have been made to conform to current reporting practices. The consolidated financial statements include the accounts of the Company and its subsidiaries after elimination of intercompany transactions and balances. The Company’s interests in oil and natural gas exploration and production ventures and partnerships are proportionately consolidated. The Company reflects a noncontrolling interest representing primarily the interest owned by the Karnes County Contributors through their ownership of Magnolia LLC Units in the consolidated financial statements. The noncontrolling interest is presented as a component of equity. See Note 11—Stockholders’ Equity for further discussion of the noncontrolling interest.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies As of June 30, 2020, the Company’s significant accounting policies are consistent with those discussed in Note 2 - Summary of Significant Accounting Policies of its consolidated and combined financial statements contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2019, with the exception of Accounts Receivable and Allowance for Expected Credit Losses and as noted below. Accounts Receivable and Allowance for Expected Credit Losses In June 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments-Credit Losses (Topic 326): “Measurement of Credit Losses on Financial Instruments.” For public business entities, the new standard became effective for annual reporting periods beginning after December 15, 2019, including interim periods within that reporting period. Magnolia adopted this standard on January 1, 2020. The standard 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 earlier recognition of allowance for losses. The Company’s receivables consist mainly of trade receivables from commodity sales and joint interest billings due from owners on properties the Company operates. The majority of these receivables have payment terms of 30 days or less. For receivables due from joint interest owners, the Company generally has the ability to withhold future revenue disbursements to recover non-payment of joint interest billings. From an evaluation of the Company’s existing credit portfolio, historical credit losses have been de minimis and are expected to remain so in the future assuming no substantial changes to the business or creditworthiness of Magnolia’s business partners. As expected, there was no material impact on the Company’s unaudited consolidated financial statements or disclosures upon adoption of this ASU. Recent Accounting Pronouncements In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): “Simplifying the Accounting for Income Taxes,” which reduces the complexity of accounting for income taxes by removing certain exceptions to the general principles and also simplifying areas such as separate entity financial statements and interim recognition of enactment of tax laws or rate changes. This standard is effective for interim and annual periods beginning after December 15, 2020 and shall be applied on either a prospective basis, a retrospective basis for all periods presented, or a modified retrospective basis through a cumulative-effect adjustment to retained earnings depending on which aspects of the new standard are applicable to an entity. The Company is currently evaluating the effect of this standard, but does not expect the adoption of this guidance to have a material impact on its financial position, cash flows, or result of operations.

Revenue Recognition

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition Magnolia’s revenues include the sale of crude oil, natural gas, and NGLs. Oil, natural gas, and NGL sales are recognized as revenue when production is sold to a customer in fulfillment of performance obligations under the terms of agreed contracts. Performance obligations are primarily comprised of delivery of oil, natural gas, or NGLs at a delivery point, as negotiated within each contract. Each barrel of oil, million Btu of natural gas, gallon of NGLs, or other unit of measure is separately identifiable and represents a distinct performance obligation to which the transaction price is allocated. The Company’s oil production is primarily sold under market-sensitive contracts that are typically priced at a differential to the New York Mercantile Exchange (“NYMEX”) price or at purchaser posted prices for the producing area. For oil contracts, the Company generally records sales based on the net amount received. For natural gas contracts, the Company generally records wet gas sales (which consists of natural gas and NGLs based on end products after processing) at the wellhead or inlet of the gas processing plant (i.e., the point of control transfer) as revenues net of gathering, transportation, and processing expenses if the processor is the customer and there is no redelivery of commodities to the Company at the tailgate of the plant. Conversely, the Company generally records residual natural gas and NGL sales at the tailgate of the plant (i.e., the point of control transfer) on a gross basis along with the associated gathering, transportation, and processing expenses if the processor is a service provider and there is redelivery of one or several commodities to the Company at the tailgate of the plant. The facts and circumstances of an arrangement are considered and judgment is often required in making this determination. For processing contracts that require noncash consideration in exchange for processing services, the Company recognizes revenue and an equal gathering, transportation, and processing expense for commodities transferred to the service provider. Customers are invoiced once the Company’s performance obligations have been satisfied. Payment terms and conditions vary by contract type, although terms generally include a requirement of payment within 30 days. There are no judgments that significantly affect the amount or timing of revenue from contracts with customers. Accordingly, the Company’s product sales contracts do not give rise to material contract assets or contract liabilities. The Company’s receivables consist mainly of trade receivables from commodity sales and joint interest billings due from owners on properties the Company operates. Receivables from contracts with customers totaled $51.3 million as of June 30, 2020 and $100.4 million as of December 31, 2019. The Company has concluded that disaggregating revenue by product type appropriately depicts how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors and has reflected this disaggregation of revenue on the Company’s consolidated statements of operations for all periods presented. Performance obligations are satisfied at a point in time once control of the product has been transferred to the customer. The Company considers a variety of facts and circumstances in assessing the point of control transfer, including but not limited to: whether the purchaser can direct the use of the hydrocarbons, the transfer of significant risks and rewards, the Company’s right to payment, and transfer of legal title. The Company does not disclose the value of unsatisfied performance obligations for contracts as all contracts have either an original expected length of one year or less, or the entire future consideration is variable and allocated entirely to a wholly unsatisfied performance obligation.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Certain of the Company’s assets and liabilities are carried at fair value and measured either on a recurring or nonrecurring basis. The Company’s fair value measurements are based either on actual market data or assumptions that other market participants would use in pricing an asset or liability in an orderly transaction, using the valuation hierarchy prescribed by GAAP under Accounting Standards Codification (“ASC”) 820. The three levels of the fair value hierarchy under ASC 820 are as follows: Level I - Quoted prices (unadjusted) in active markets for identical investments at the measurement date are used. Level II - Pricing inputs are other than quoted prices included within Level I that are observable for the investment, either directly or indirectly. Level II pricing inputs include quoted prices for similar investments in active markets, quoted prices for identical or similar investments in markets that are not active, inputs other than quoted prices that are observable for the investment, and inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level III - Pricing inputs are unobservable and include situations where there is little, if any, market activity for the investment. The inputs used in determination of fair value require significant judgment and estimation. Fair Value of Financial Instruments Debt Obligations The carrying value and fair value of the financial instrument that is not carried at fair value in the accompanying consolidated balance sheet at June 30, 2020 and December 31, 2019 is as follows: June 30, 2020 December 31, 2019 (In thousands) Carrying Value Fair Value Carrying Value Fair Value Long-term debt $ 390,464 $ 383,444 $ 389,835 $ 412,000 The fair value of the 2026 Senior Notes at June 30, 2020 and December 31, 2019 was based on unadjusted quoted prices in an active market, which are considered a Level 1 input in the fair value hierarchy. The Company has other financial instruments consisting primarily of receivables, payables, 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 business combinations and asset retirement obligations. Nonrecurring Fair Value Measurements The Company applies the provisions of the fair value measurement standard on a nonrecurring basis to its non-financial assets and liabilities, including oil and natural gas properties. These assets and liabilities are not measured at fair value on a recurring basis but are subject to fair value adjustments when facts and circumstances arise that indicate a need for remeasurement. During the first quarter of 2020, Magnolia recorded impairments of $1.9 billion related to proved and unproved properties as a result of a sharp decline in commodity prices. Proved property impairment of $1.4 billion is included in “Impairment of oil and natural gas properties” and unproved property impairment of $0.6 billion is included in “Exploration expense” on the Company’s consolidated statement of operations. Proved and unproved properties that were impaired had aggregate fair values of $0.8 billion and $0.3 billion, respectively. The fair values of these oil and natural gas properties were measured using the income approach based on inputs that are not observable in the market, and therefore, represent Level 3 inputs. The Company calculated the estimated fair values of its oil and natural gas properties using a discounted future cash flow model. Significant inputs associated with the calculation of discounted future net cash flows include estimates of future commodity prices based on NYMEX strip pricing adjusted for price differentials, estimates of proved oil and natural gas reserves and risk adjusted probable and possible reserves, estimates of future expected operating and capital costs, and a market participant based weighted average cost of capital of 10% for proved property impairments and 12% for unproved property impairments.

The borrowing base as of June 30, 2020 was $450.0 million. The RBL Facility is guaranteed by certain parent companies and subsidiaries of Magnolia LLC and is collateralized by certain of Magnolia Operating’s oil and natural gas properties and has a borrowing base subject to semi-annual redetermination. Borrowings under the RBL Facility bear interest, at Magnolia Operating’s option, at a rate per annum equal to either the LIBOR rate or the alternative base rate plus the applicable margin. Additionally, Magnolia Operating is required to pay a commitment fee quarterly in arrears in respect of unused commitments under the RBL Facility. The applicable margin and the commitment fee rate are calculated based upon the utilization levels of the RBL Facility as a percentage of the borrowing base then in effect. The RBL Facility contains certain affirmative and negative covenants customary for financings of this type, including compliance with a leverage ratio of less than 4.00 to 1.00 and, if the leverage ratio is in excess of 3.00 to 1.00, a current ratio of greater than 1.00 to 1.00. As of June 30, 2020, the Company was in compliance with all covenants under the RBL Facility. Deferred financing costs incurred in connection with securing the RBL Facility were $11.7 million, which are amortized on a straight-line basis over a period of five years and included in “Interest expense, net” in the Company’s consolidated statements of operations. The Company recognized interest expense related to the RBL Facility of $1.0 million and $1.1 million for the three months ended June 30, 2020 and 2019, respectively, and $2.2 million for each of the six months ended June 30, 2020 and 2019. The unamortized portion of the deferred financing costs are included in “Deferred financing costs, net” on the accompanying consolidated balance sheet as of June 30, 2020. The Company did not have any outstanding borrowings under its RBL Facility as of June 30, 2020. 2026 Senior Notes On July 31, 2018, the Issuers issued and sold $400.0 million aggregate principal amount of 2026 Senior Notes. The 2026 Senior Notes were issued under the Indenture, dated as of July 31, 2018 (the “Indenture”), by and among the Issuers and Deutsche Bank Trust Company Americas, as trustee. The 2026 Senior Notes are guaranteed on a senior unsecured basis by the Company, Magnolia Operating, and Magnolia Intermediate and may be guaranteed by certain future subsidiaries of the Company. The 2026 Senior Notes will mature on August 1, 2026 and bear interest at the rate of 6.0% per annum. At any time prior to August 1, 2021, the Issuers may, on any one or more occasions, redeem all or a part of the 2026 Senior Notes at a redemption price equal to 100% of the principal amount of the 2026 Senior Notes redeemed, plus a “make whole” premium on accrued and unpaid interest, if any, to, but excluding, the date of redemption. After August 1, 2021, the Issuers may redeem all or a part of the 2026 Senior Notes based on principal plus a set premium, as set forth in the Indenture, including any accrued and unpaid interest. The Company incurred $11.8 million of deferred financing costs related to the issuance of the 2026 Senior Notes, which were capitalized. These costs are amortized using the effective interest method over the term of the 2026 Senior Notes and are included in “Interest expense, net” in the Company’s consolidated statements of operations. The unamortized portion of the deferred financing costs is included as a reduction to the carrying value of the 2026 Senior Notes, which have been recorded as “Long-term debt, net” on the consolidated balance sheet as of June 30, 2020. The Company recognized interest expense related to the 2026 Senior Notes of $6.3 million for each of the three months ended June 30, 2020 and 2019, and $12.6 million for each of the six months ended June 30, 2020 and 2019. Affiliate Guarantors The Company, Magnolia LLC and Magnolia Intermediate (together with the Company, the “Parent Guarantors”), and certain subsidiaries of Magnolia Operating are guarantors under the terms of its 2026 Senior Notes and RBL Facility. The Parent Guarantors may be released upon the request of Magnolia Operating. Magnolia’s consolidated financial statements reflect the financial position of these subsidiary guarantors. As the parent company, Magnolia has no independent operations. The guarantees are full and unconditional (except for customary release provisions) and joint and several. There are restrictions on dividends, distributions, loans, or other transfers of funds from the subsidiary guarantors to the Company.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal Matters The Company is involved in disputes or legal actions in the ordinary course of business. For example, certain of the Karnes County Contributors and the Company have been named as defendants in a lawsuit where the plaintiffs claim to be entitled to a minority working interest in certain Karnes County Assets. The litigation is in the pre-trial stage. The exposure related to this litigation is currently not reasonably estimable. The Karnes County Contributors retained all such liability in connection with the Business Combination. At June 30, 2020, the Company does not believe the outcome of any such disputes or legal actions will have a material effect on its consolidated statements of operations, balance sheet, or cash flows. No amounts were accrued with respect to outstanding litigation at June 30, 2020 or June 30, 2019. Environmental Matters The Company, as an owner or lessee and operator of oil and natural gas properties, is subject to various federal, state, local laws, and regulations relating to discharge of materials into, and protection of, the environment. These laws and regulations may, among other things, impose liability on the lessee under an oil and natural gas lease for the cost of pollution clean-up resulting from operations and subject the lessee to liability for pollution damages. In some instances, the Company may be directed to suspend or cease operations in the affected area. The Company maintains insurance coverage, which it believes is customary in the industry, although the Company is not fully insured against all environmental risks. Risks and Uncertainties The Company’s revenue, profitability, and future growth are substantially dependent upon the prevailing and future prices for oil and natural gas, which depend on numerous factors beyond the Company’s control such as overall oil and natural gas production and inventories in relevant markets, economic conditions, the global political environment, regulatory developments, and competition from other energy sources. Oil and natural gas prices historically have been volatile and may be subject to significant fluctuations in the future. The coronavirus disease 2019 (“COVID-19”) pandemic and related economic repercussions have created significant volatility, uncertainty, and turmoil in the oil and natural gas industry. Oil demand has significantly deteriorated as a result of the virus outbreak and corresponding preventative measures taken around the world to mitigate the spread of the virus. The implications of the decrease in global demand for oil, coupled with the general oversupply, may have further negative effects on the Company’s business, such as production curtailment, reduced storage capacity, and reductions to its operating plans. During the second quarter of 2020, and thus far during the third quarter of 2020, there have been continued and, in certain cases, increasing outbreaks of COVID-19 in the United States, particularly in Texas, where Magnolia conducts substantially all of its operations. Demand and pricing may again decline due to the resurgence of the outbreak across the U.S. and other locations across the world and the related social distancing guidelines, travel restrictions, and stay-at-home orders. The extent of the additional impact on the Company’s industry and its business cannot be reasonably predicted at this time.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company estimates its annual effective tax rate in recording its quarterly provision for income taxes in the various jurisdictions in which it operates. On March 27, 2020, the United States enacted the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”). The CARES Act includes several significant business tax provisions that, among other things, allow businesses to carry back net operating losses (“NOL”) arising in 2018, 2019, and 2020 to the five prior tax years. Applying the NOL carryback provision resulted in an income tax benefit of $1.2 million during the six months ended June 30, 2020. The difference in the U.S. federal statutory tax rate of 34% in 2017 compared to 21% in 2018 and thereafter results in a discrete benefit to the tax provision of approximately $0.4 million for the six months ended June 30, 2020. The income tax expense or benefit recorded for the period is based on applying an estimated annual effective income tax rate to the net income or loss for the three and six months ended June 30, 2020 and 2019. The computation of the annual estimated effective tax rate at each interim period requires certain estimates and significant judgment including, but not limited to, the Company’s expected operating income for the year, projections of the proportion of income earned and taxed in various jurisdictions, the effect of noncontrolling interest, permanent and temporary differences, and the likelihood of recovering deferred tax assets in the current year. The accounting estimates used to compute the income tax expense or benefit may change as new events occur, more experience is obtained, additional information becomes known, or as the tax environment changes. The Company’s effective tax rate for the three months ended June 30, 2020 and 2019 was 9.8% and 14.1%, respectively. The Company’s effective tax rate for the six months ended June 30, 2020 and 2019 was 3.9% and 14.2%, respectively. The primary differences between the effective tax rate and the federal statutory tax rate of 21.0% are income attributable to noncontrolling interest, the recognition of a valuation allowance on federal and state deferred tax assets, and state taxes. During the six months ended June 30, 2020, Magnolia’s effective tax rate was primarily impacted by the reversal of its deferred tax liability, the recognition of valuation allowances for its deferred tax assets from non-cash impairments of the carrying value of the Company’s oil and natural gas properties, and the net deferred tax assets generated in this period. During the first quarter of 2020, the Company moved from a net deferred tax liability position to an estimated net deferred tax asset position resulting primarily from oil and natural gas impairments. As of June 30, 2020, the Company’s net deferred tax asset was $206.3 million. Management assessed whether it is more-likely-than-not that it will generate sufficient taxable income to realize its deferred income tax assets, including the investment in partnership and net operating loss carryforwards. In making this determination, the Company considered all available positive and negative evidence and made certain assumptions. The Company considered, among other things, the overall business environment, its historical earnings and losses, current industry trends, and its outlook for future years. As of June 30, 2020, the Company assessed the realizability of the deferred tax assets and recorded a full valuation allowance of $206.3 million. The Company’s income tax provision consists of the following components: Three Months Ended Six Months Ended (In thousands) June 30, 2020 June 30, 2019 June 30, 2020 June 30, 2019 Current: Federal $ 5 $ (176) $ (1,167) $ — State — 386 — 569 5 210 (1,167) 569 Deferred: Federal (2,916) 5,092 (71,792) 8,454 State (265) (157) (6,042) (103) (3,181) 4,935 (77,834) 8,351 Total provision $ (3,176) $ 5,145 $ (79,001) $ 8,920 The Company is subject to U.S. federal income tax, the margin tax in the state of Texas, and Louisiana corporate income tax. No amounts have been accrued for income tax uncertainties or interest and penalties as of June 30, 2020. The Company is currently not aware of any issues under review that could result in significant payments, accruals, or material deviation from its position. The Company’s tax years since its formation remain subject to possible income tax examinations by its major taxing authorities for all periods.

Equity [Abstract]
Stockholders' Equity	Stockholders’ Equity Class A Common Stock At June 30, 2020, there were 168.6 million shares of Class A Common Stock issued and 166.6 million shares of Class A Common Stock outstanding. The holders of Class A Common Stock and Class B Common Stock vote together as a single class on all matters and are entitled one vote for each share held. There is no cumulative voting with respect to the election of directors, which results in the holders of more than 50% of the shares being able to elect all of the directors, subject to voting obligations under the Stockholder Agreement. In the event of a liquidation, dissolution, or winding up of Magnolia Oil & Gas Corporation, the holders of the Class A Common Stock are entitled to share ratably in all assets remaining available for distribution to them after payment of liabilities and after provision is made for each class of stock, if any, having preference over the common stock. The holders of the Class A Common Stock have no preemptive or other subscription rights, and there are no sinking fund provisions applicable to such shares. Class B Common Stock At June 30, 2020, there were 85.8 million shares of Class B Common Stock issued and outstanding. Holders of Class B Common Stock vote together as a single class with holders of Class A Common Stock on all matters properly submitted to a vote of the stockholders. The holders of Class B Common Stock generally have the right to exchange all or a portion of their Class B Common Stock, together with an equal number of Magnolia LLC Units, for the same number of shares of Class A Common Stock or, at Magnolia LLC’s option, an equivalent amount of cash. Upon the future redemption or exchange of Magnolia LLC Units held by any holder of Class B Common Stock, a corresponding number of shares of Class B Common Stock held by such holder of Class B Common Stock will be canceled. In the event of a liquidation, dissolution, or winding up of Magnolia LLC, the holders of the Class B Common Stock, through their ownership of Magnolia LLC Units, are entitled to share ratably in all assets remaining available for distribution to them after payment of liabilities and after provision is made for each class of units of Magnolia LLC, if any, having preference over the common units. The holders of the Class B Common Stock have no preemptive or other subscription rights, and there are no sinking fund provisions applicable to such shares. Share Repurchase Program On August 5, 2019, the Company’s board of directors authorized a share repurchase program of up to 10 million shares of Class A Common Stock. The program does not require purchases to be made within a particular timeframe. As of June 30, 2020, the Company had repurchased 2.0 million shares under the plan at a cost of $16.8 million. No shares were repurchased in the second quarter of 2020. Noncontrolling Interest Noncontrolling interest in Magnolia’s consolidated subsidiaries include amounts attributable to Magnolia LLC Units that were issued to the Karnes County Contributors in connection with the Business Combination. The noncontrolling interest percentage is affected by various equity transactions such as issuances of Class A Common Stock, the exchange of Class B Common Stock (and corresponding Magnolia LLC Units) for Class A Common Stock, or the cancellation of Class B Common Stock (and corresponding Magnolia LLC Units). As of June 30, 2020, Magnolia owned approximately 66% of the interest in Magnolia LLC and the noncontrolling interest was 34%. In the first quarter of 2019, Magnolia Operating formed Highlander as a joint venture where MGY Louisiana LLC, a wholly owned subsidiary of Magnolia Operating, holds approximately 85% of the units in Highlander, with the remaining 15% attributable to noncontrolling interest.

Share-based Payment Arrangement [Abstract]
Stock Based Compensation	Stock Based Compensation On October 8, 2018, the Company’s board of directors adopted the “Magnolia Oil & Gas Corporation Long Term Incentive Plan” (the “Plan”), effective as of July 17, 2018. A total of 11.8 million shares of Class A Common Stock have been authorized for issuance under the Plan. The Company grants stock based compensation awards in the form of restricted stock units (“RSUs”) and performance stock units (“PSUs”) to eligible employees and directors to enhance the Company and its affiliates’ ability to attract, retain, and motivate persons who make important contributions to the Company and its affiliates by providing these individuals with equity ownership opportunities. Shares issued as a result of awards granted under the Plan are generally new shares of Class A Common Stock. Stock based compensation expense is recognized net of forfeitures within “General and administrative expenses” on the consolidated statements of operations and was $3.1 million for each of the three months ended June 30, 2020 and 2019, and $5.9 million and $5.5 million for the six months ended June 30, 2020 and 2019, respectively. The Company has elected to account for forfeitures of awards granted under the Plan as they occur in determining compensation expense. Restricted Stock Units The Company grants service-based RSU awards to employees and non-employee directors, which generally vest ratably over a three-year service period, in the case of awards to employees, and vest in full after one year, in the case of awards to directors. RSUs represent the right to receive shares of Class A Common Stock at the end of the vesting period equal to the number of RSUs that vest. RSUs are subject to restrictions on transfer and are generally subject to a risk of forfeiture if the award recipient ceases to be an employee or director of the Company for any reason prior to vesting of the award. Compensation expense for the service-based RSU awards is based upon the grant date market value of the award and such costs are recorded on a straight-line basis over the requisite service period for each separately vesting portion of the award, as if the award was, in-substance, multiple awards. Unrecognized compensation expense related to unvested RSUs as of June 30, 2020 was $12.6 million, which the Company expects to recognize over a weighted average period of 1.9 years. The table below summarizes RSU activity for the three and six months ended June 30, 2020: Three Months Ended Six Months Ended June 30, 2020 June 30, 2020 Restricted Stock Units Weighted Average Grant Date Fair Value Restricted Stock Units Weighted Average Grant Date Fair Value Unvested RSUs, beginning of period 1,572,400 $ 10.60 1,099,901 $ 12.97 Granted 167,022 5.95 853,367 7.16 Vested (101,977) 12.25 (315,823) 12.54 Forfeited — — — — Unvested RSUs, end of period 1,637,445 $ 10.02 1,637,445 $ 10.02 Performance Stock Units During the six months ended June 30, 2020, the Company granted PSUs to certain employees. Each PSU, to the extent earned, represents the contingent right to receive one share of Class A Common Stock and the awardee may earn between zero and 150% of the target number of PSUs granted based on the total shareholder return (“TSR”) of the Class A Common Stock relative to the TSR achieved by a specific industry peer group over a three-year performance period, the last day of which is also the vesting date. In addition to the TSR conditions, vesting of the PSUs is subject to the awardee’s continued employment through the date of settlement of the PSUs, which will occur within 60 days following the end of the performance period. Unrecognized compensation expense related to unvested PSUs as of June 30, 2020 was $6.4 million, which the Company expects to recognize over a weighted average period of 1.8 years.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Jun. 30, 2020
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial reporting. Accordingly, certain disclosures normally included in an Annual Report on Form 10-K have been omitted. The consolidated financial statements and related notes included in this Quarterly Report should be read in conjunction with the Company’s consolidated and combined financial statements and related notes included in the Company’s Annual Report on Form 10-K for the period ended December 31, 2019. Except as disclosed herein, there have been no material changes to the information disclosed in the notes to the consolidated and combined financial statements included in the Company’s Annual Report on Form 10-K for the period ended December 31, 2019. In the opinion of management, all normal, recurring adjustments and accruals considered necessary to present fairly, in all material respects, the Company’s interim financial results, have been included. Operating results for the periods presented are not necessarily indicative of expected results for the full year. Certain reclassifications of prior period financial statements have been made to conform to current reporting practices. The consolidated financial statements include the accounts of the Company and its subsidiaries after elimination of intercompany transactions and balances. The Company’s interests in oil and natural gas exploration and production ventures and partnerships are proportionately consolidated. The Company reflects a noncontrolling interest representing primarily the interest owned by the Karnes County Contributors through their ownership of Magnolia LLC Units in the consolidated financial statements. The noncontrolling interest is presented as a component of equity. See Note 11—Stockholders’ Equity for further discussion of the noncontrolling interest.
Accounts Receivable and Allowance for Expected Credit Losses	Accounts Receivable and Allowance for Expected Credit Losses In June 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments-Credit Losses (Topic 326): “Measurement of Credit Losses on Financial Instruments.” For public business entities, the new standard became effective for annual reporting periods beginning after December 15, 2019, including interim periods within that reporting period. Magnolia adopted this standard on January 1, 2020. The standard 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 earlier recognition of allowance for losses. The Company’s receivables consist mainly of trade receivables from commodity sales and joint interest billings due from owners on properties the Company operates. The majority of these receivables have payment terms of 30 days or less. For receivables due from joint interest owners, the Company generally has the ability to withhold future revenue disbursements to recover non-payment of joint interest billings. From an evaluation of the Company’s existing credit portfolio, historical credit losses have been de minimis and are expected to remain so in the future assuming no substantial changes to the business or creditworthiness of Magnolia’s business partners. As expected, there was no material impact on the Company’s unaudited consolidated financial statements or disclosures upon adoption of this ASU.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): “Simplifying the Accounting for Income Taxes,” which reduces the complexity of accounting for income taxes by removing certain exceptions to the general principles and also simplifying areas such as separate entity financial statements and interim recognition of enactment of tax laws or rate changes. This standard is effective for interim and annual periods beginning after December 15, 2020 and shall be applied on either a prospective basis, a retrospective basis for all periods presented, or a modified retrospective basis through a cumulative-effect adjustment to retained earnings depending on which aspects of the new standard are applicable to an entity. The Company is currently evaluating the effect of this standard, but does not expect the adoption of this guidance to have a material impact on its financial position, cash flows, or result of operations.
