NOTE 1 —- BUSINESS AND BASIS OF PRESENTATION

Description of the Business

Black Stone Minerals, L.P. (“BSM” or the “Partnership”) is a publicly traded Delaware limited partnership that owns oil and natural gas mineral interests, which make up the vast majority of the asset base. The Partnership's assets also include nonparticipating royalty interests and overriding royalty interests. These interests, which are substantially non-cost-bearing, are collectively referred to as “mineral and royalty interests.” The Partnership’s mineral and royalty interests are located in 41 states in the continental United States, including all of the major onshore producing basins. The Partnership also owns non-operated working interests in certain oil and natural gas properties. The Partnership's common units trade on the New York Stock Exchange under the symbol "BSM."

Basis of Presentation

The accompanying unaudited interim consolidated financial statements of the Partnership have been prepared in accordance with generally accepted accounting principles ("GAAP") in the United States and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). These unaudited interim consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and, therefore, do not include all disclosures required for financial statements prepared in conformity with GAAP. Accordingly, the accompanying unaudited interim consolidated financial statements and related notes should be read in conjunction with the Partnership’s consolidated financial statements included in the Partnership’s Annual Report on Form 10-K for the year ended December 31, ~~2018~~2019 ("~~2018~~2019 Annual Report on Form 10-K").

The unaudited interim consolidated financial statements include the consolidated results of the Partnership. The results of operations for the ~~six~~three months ended ~~June 30, 2019~~March 31, 2020 are not necessarily indicative of the results to be expected for the full year.

In the opinion of management, all adjustments, which are of a normal and recurring nature, necessary for the fair presentation of the financial results for all periods presented have been reflected. All intercompany balances and transactions have been eliminated.

The Partnership evaluates the significant terms of its investments to determine the method of accounting to be applied to each respective investment. Investments in which the Partnership has less than a 20% ownership interest and does not have control or exercise significant influence are accounted for using fair value or cost minus impairment if fair value is not readily determinable. Investments in which the Partnership exercises control are consolidated, and the noncontrolling interests of such investments, which are not attributable directly or indirectly to the Partnership, are presented as a separate component of net income (loss) and ~~equity in the accompanying unaudited interim consolidated financial statements.~~equity.

The unaudited interim consolidated financial statements include undivided interests in oil and natural gas property rights. The Partnership accounts for its share of oil and natural gas property rights by reporting its proportionate share of assets, liabilities, revenues, costs, and cash flows within the relevant lines on the accompanying unaudited interim consolidated balance sheets, statements of operations, and statements of cash flows.

Segment Reporting

The Partnership operates in a single operating and reportable segment. Operating segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and assess performance. The Partnership’s chief executive officer has been determined to be the chief operating decision maker and allocates resources and assesses performance based upon financial information at the consolidated level.

Recent Accounting Pronouncements

~~In February 2016,~~On January 1, 2020, the ~~Financial Accounting Standards Board ("FASB") issued~~Partnership adopted Accounting Standards Update ("ASU") ~~2016-02,~~ ~~Leases(Topic 842)~~ ~~("ASC 842"), that supersedes Accounting Standards Codification ("ASC") 840,~~ ~~Leases~~ by requiring lessees to recognize lease assets and lease liabilities classified as operating leases on the balance sheet. See Note 3 - Impact of ASC 842 Adoption for further details related to the Partnership's adoption of this standard.

~~In August 2018, the FASB issued ASU~~ 2018-13, Fair Value ~~Measurement~~Measurements (Topic 820),, which ~~will remove, modify,~~removed, modified, and ~~add~~added certain required disclosures on fair value measurements. As amended, Topic 820 will no longer require the disclosure of the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, the policy of timing of transfers between levels, and the valuation processes for Level 3 fair value measurements. In addition, certain modifications to current disclosure requirements will be made, including clarifying that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date. Certain disclosure requirements will also be added, including the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. For certain unobservable inputs, an entity may disclose other quantitative information in place of the weighted average if the entity determines that other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements. The new standard will be effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, and early adoption is permitted. The Partnership does not plan to early adopt and is evaluating the impact that the new accounting guidance will have on its consolidated financial statements and related disclosures.

~~NOTE 3 — IMPACT OF ASC 842 ADOPTION~~

~~Leases~~

On January 1, 2019, the Partnership adopted ASC 842 using the modified retrospective method. ASC 842 requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under the previous guidance. The Partnership used January 1, 2019, the beginning of the period of adoption, as its date of initial application. The Partnership elected the package of practical expedients upon transition which will retain the lease classification for leases and any unamortized initial direct costs that existed prior to the adoption of the standard.

The adoption of the standard resulted in the recognition of operating lease right-of-use (“ROU”) assets and operating lease liabilities on the consolidated balance sheet as of January 1, 2019. ROU assets and operating lease liabilities were less than 1% of the Partnership's total assets as of June 30, 2019 and were not considered material to the Partnership. There was no related impact on the consolidated statement of operations. The standardthis update had no impact on the ~~Partnership’s debt covenant compliance under existing agreements.~~

~~BLACK STONE MINERALS, L.P. AND SUBSIDIARIES~~

~~NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS~~

The Partnership determines if an arrangement is a lease at inception by considering whether (1) explicitly or implicitly identified assets have been deployed in the agreement and (2) the Partnership obtains substantially all of the economic benefits from the use of that underlying asset and directs how and for what purpose the asset is used during the term of the agreement. Operating leases are included in Deferred charges and other long-term assets, Other current liabilities, and Other long-term liabilities in the consolidated balance sheets. As of June 30, 2019, none of the Partnership’s leases were classified as financing leases.

ROU assets represent the Partnership’s right to use an underlying asset for the lease term and operating lease liabilities represent the Partnership’s obligation to make lease payments arising from the lease. ROU assets are recognized at commencement date and consist of the present value of remaining lease payments over the lease term, initial direct costs, prepaid lease payments less any lease incentives. Operating lease liabilities are recognized at commencement date based on the present value of remaining lease payments over the lease term. The Partnership uses the implicit rate, when readily determinable, or its incremental borrowing rate based on the information available at commencement date to determine the present value of lease payments.

The lease terms may include periods covered by options to extend the lease when it is reasonably certain that the Partnership will exercise that option and periods covered by options to terminate the lease when it is not reasonably certain that the Partnership will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Partnership made an accounting policy election to not recognize leases with terms of less than twelve months on the consolidated balance sheets and recognize those lease payments in the consolidated statementsPartnership's financial position, results of operations, ~~on a straight-line basis over the lease term. In the event that the Partnership’s assumptions and expectations change, it may have to revise its ROU assets and operating lease liabilities.~~or liquidity.

NOTE ~~4 —~~3 - OIL AND NATURAL GAS PROPERTIES

Acquisitions of proved oil and natural gas properties and working interests are generally considered business combinations and are recorded at their estimated fair value as of the acquisition date. Acquisitions that consist of all or substantially all unproved oil and natural gas properties are generally considered asset acquisitions and are recorded at cost.

2020 Acquisitions

The Partnership had no acquisition activity during the three months ended March 31, 2020.

2019 Acquisitions

During the ~~six months~~year ended ~~June 30,~~December 31, 2019, the Partnership closed on multiple acquisitions of mineral and royalty interests for total consideration of ~~$41.6~~$44.0 million.

Acquisitions that were considered business combinations were primarily located in the Permian Basin. These acquisitions were funded with borrowings under the Credit Facility (as defined in Note 76 - Credit Facility) and funds from operating activities. Acquisition related costs of less than $0.1 million were expensed and included in the General and administrative line item of the consolidated statement of operations for the ~~six months~~year ended ~~June 30,~~December 31, 2019.

Canaan Farmout

On February 21, 2017, the Partnership announced that it had entered into a farmout agreement with Canaan Resource Partners ("Canaan") which covers certain Haynesville and Bossier shale acreage in San Augustine County, Texas operated by XTO Energy Inc., a subsidiary of Exxon Mobil Corporation. The Partnership has an approximate 50% working interest in the acreage and is the largest mineral owner. A total of 20 wells were drilled over an initial phase, beginning with wells spud after January 1, 2017. Canaan elected to participate in an additional phase that began in September 2018 and continues for the lesser of 2 years or until 20 wells have been drilled. As of March 31, 2020, a total of 17 wells have been drilled during the second phase. After the completion of the second phase, Canaan will have the option to elect to participate in a similar third phase. During the first ~~three~~3 phases of the agreement, Canaan commits on a phase-by-phase basis and funds 80% of the Partnership's drilling and completion costs and is assigned 80% of the Partnership's working interests in such wells (40% working interest on an 8/8ths basis) as the wells are drilled. After the third phase, Canaan can earn 40% of the Partnership’s working interest (20% working interest on an 8/8ths basis) in additional wells drilled in the area by continuing to

~~BLACK STONE MINERALS, L.P. AND SUBSIDIARIES~~

~~NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS~~

fund 40% of the Partnership's costs for those wells on a well-by-well basis. The Partnership receives an overriding royalty interest (“ORRI”) before payout and an increased ORRI after payout on all wells drilled under the agreement. From the inception of the agreement through June 30, 2019, the Partnership has received $89.2 million from Canaan under the agreement. When working interests in farmout wells are assigned to Canaan, the Partnership's Oil and natural gas properties and Other long-term liabilities are reduced by the reimbursed capital costs. As of June 30, 2019, the Partnership had assigned to Canaan working interests in certain wells drilled and completed, and as such, $0.9 million of the farmout reimbursements received from Canaan are included in the Other long-term liabilities line item of the consolidated balance sheet.

Pivotal Farmout

On November 21, 2017, the Partnership entered into a farmout agreement with Pivotal Petroleum Partners (“Pivotal”), a portfolio company of Tailwater Capital, LLC. The farmout agreement covers substantially all of the Partnership's remaining working interests under active development in the Shelby Trough area of East Texas, targeting the Haynesville and Bossier shale acreage (after giving effect to the Canaan Farmout), until November 2025. Pivotal will earn the Partnership's remaining working interest in wells operated by XTO Energy Inc. in San Augustine County, Texas not covered by the Canaan Farmout (10% working interest on an 8/8th basis), as well as 100% of the Partnership's working interests (ranging from approximately 12.5% to 25% on an 8/8ths basis) in wells operated by ~~its other major operator~~BPX Energy in San Augustine and Angelina counties, Texas. Initially, Pivotal is obligated to fund the development of up to 80 wells, in designated well groups, across several development areas and then has options to continue funding the Partnership's working interest across those areas for the duration of the farmout agreement. ~~Pivotal will fund designated groups of wells.~~ Once Pivotal achieves a specified payout for a designated well group, the Partnership will obtain a majority of the original working interest in such well group. As of March 31, 2020, a total of 68 wells have been drilled in the contract area. The Partnership's development agreement with BPX Energy terminated in 2019 with respect to the majority of the Partnership's acreage covered by the farmout agreement with Pivotal. As such, Pivotal retains minimal rights or obligations related to the farmout for that area. The Partnership remains engaged with Pivotal around farmout opportunities with potential new operators in the area forfeited by BPX Energy.

From the inception of the ~~agreement~~farmout agreements through ~~June 30, 2019,~~March 31, 2020, the Partnership has received ~~$102.0~~$90.3 million and $118.6 million from Canaan and Pivotal, respectively, under the ~~agreement.~~agreements. When such reimbursements are received prior to assigning the wells to Canaan and Pivotal, the Partnership records the amounts as increases to Oil and natural gas properties and Other long-term liabilities. When working interests in farmout wells are assigned to Canaan and Pivotal, the Partnership's Oil and natural gas properties and Other long-term liabilities are reduced by the reimbursed capital costs. As of ~~June 30,~~March 31, 2020 and December 31, 2019, ~~the Partnership had assigned to Pivotal working interests in certain wells drilled~~$0.1 million and ~~completed, and as such, $75.0~~$1.7 million, ~~of the farmout reimbursements received from Pivotal are~~respectively, was included in the Other long-term liabilities line item of the consolidated balance ~~sheet.~~sheets for reimbursements received associated with farmed-out working interests not yet assigned to Canaan and Pivotal.

Impairment of ~~December 31, 2018, $11.6 million~~Oil and ~~$41.2 million were included~~Natural Gas Properties

Proved and unproved oil and natural gas properties are reviewed for impairment when events and circumstances indicate a possible decline in the ~~Other long-term liabilities line item~~recoverability of the ~~consolidated balance sheet related~~carrying value of those properties. When assessing producing properties for impairment, the Partnership compares the expected undiscounted projected future cash flows of the producing properties to the ~~farmout agreements with Canaan~~carrying amount of the producing properties to determine recoverability. When the carrying amount exceeds its estimated undiscounted future cash flows, the carrying amount is written down to its fair value, which is measured as the present value of the projected future cash flows of such properties.

There was a collapse in oil prices during the first quarter of 2020 due to geopolitical events that increased supply at the same time demand weakened due to the impact of the COVID-19 pandemic. The Partnership determined these events and ~~Pivotal, respectively.~~circumstances indicated a possible decline in the recoverability of the carrying value of certain proved properties and recoverability testing determined that certain depletable units consisting of mature oil producing properties were impaired. The Partnership recognized impairment of oil and natural gas properties of $51.0 million for three months ended March 31, 2020. NaN impairment of oil and natural gas properties was recognized during 2019. See Note 5 - Fair Value Measurements for further discussion

NOTE ~~5 —~~4 - COMMODITY DERIVATIVE FINANCIAL INSTRUMENTS

The Partnership’s ongoing operations expose it to changes in the market price for oil and natural gas. To mitigate the inherent commodity price risk associated with its operations, the Partnership uses oil and natural gas commodity derivative financial instruments. From time to time, such instruments may include variable-to-fixed-price swaps, costless collars, fixed-price contracts and other contractual arrangements. The Partnership enters into oil and natural gas derivative contracts that contain netting arrangements with each counterparty. The Partnership does not enter into derivative instruments for speculative purposes.

As of ~~June 30, 2019,~~March 31, 2020, the Partnership’s open derivative contracts consisted of fixed-price swap contracts and costless collar contracts. A fixed-price swap contract between the Partnership and the counterparty specifies a fixed commodity price and a future settlement date. A costless collar contract between the Partnership and the counterparty specifies a floor and a ceiling commodity price and a future settlement date. The Partnership has not designated any of its contracts as fair value or cash flow hedges. Accordingly, the changes in the fair value of the contracts are included in the consolidated statement of operations in the period of the change. All derivative gains and losses from the Partnership’s derivative contracts have been recognized in revenue in the Partnership's accompanying consolidated statements of operations. Derivative instruments that have not yet been settled in cash are reflected as either derivative assets or liabilities in the Partnership’s accompanying consolidated balance sheets as of ~~June 30, 2019~~March 31, 2020 and December 31, ~~2018.~~2019. See Note ~~6 –~~5 - Fair Value Measurements for further discussion.

The Partnership's derivative contracts expose it to credit risk in the event of nonperformance by counterparties that may adversely impact the fair value of the Partnership's commodity derivative assets. While the Partnership does not require its derivative contract counterparties to post collateral, the Partnership does evaluate the credit standing of such counterparties as deemed appropriate. This evaluation includes reviewing a counterparty’s credit rating and latest financial information. As of ~~June 30, 2019,~~March 31, 2020, the Partnership had ~~nine~~8 counterparties, all of which are rated Baa1 or better by Moody’s and are lenders under the Credit Facility.

NOTE ~~6 —~~5 - FAIR VALUE MEASUREMENTS

Fair value is defined as the amount at which an asset (or liability) could be bought (or incurred) or sold (or settled) in an orderly transaction between market participants at the measurement date. Further, ASC 820, Fair Value Measurement, establishes a framework for measuring fair value, establishes a fair value hierarchy based on the quality of inputs used to measure fair value, and includes certain disclosure requirements. Fair value estimates are based on either (i) actual market data or (ii) assumptions that other market participants would use in pricing an asset or liability, including estimates of risk.

ASC 820 establishes a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy categorizes assets and liabilities measured at fair value into one of three different levels depending on the observability of the inputs employed in the measurement. The three levels are defined as follows:

Level 1—Unadjusted quoted prices for identical assets or liabilities in active markets.

Level 2—Quoted prices for similar assets or liabilities in non-active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

Level 3—Inputs that are unobservable and significant to the fair value measurement (including the Partnership’s own assumptions in determining fair value).

A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The Partnership’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. ~~There were no transfers into, or out of, the three levels of the fair value hierarchy for the six months ended June 30, 2019 or the year ended December 31, 2018.~~

The carrying value of the Partnership's cash and cash equivalents, receivables, and payables approximate fair value due to the short-term nature of the instruments. The estimated carrying value of all debt as of ~~June 30, 2019~~March 31, 2020 and December 31, ~~2018~~2019 approximated the fair value due to variable market rates of interest. These debt fair values, which are Level 3 measurements, were estimated based on the Partnership’s incremental borrowing rates for similar types of borrowing arrangements, when quoted market prices were not available. The estimated fair values of the Partnership’s financial instruments are not necessarily indicative of the amounts that would be realized in a current market exchange.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The Partnership estimated the fair value of derivative instruments using the market approach via a model that uses inputs that are observable in the market or can be derived from, or corroborated by, observable data. See Note ~~5 –~~4 - Commodity Derivative Financial Instruments for further discussion.

Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis

Nonfinancial assets and liabilities measured at fair value on a non-recurring basis include certain nonfinancial assets and liabilities as may be acquired in a business combination and measurements of oil and natural gas property values for assessment of impairment.

The determination of the fair values of proved and unproved properties acquired in business combinations are estimated by discounting projected future cash flows. The factors used to determine fair value include estimates of economic reserves, future operating and development costs, future commodity prices, timing of future production, and a risk-adjusted discount rate. The Partnership has designated these measurements as Level 3. The Partnership’s fair value assessments for recent acquisitions are included in Note ~~4 –~~3 - Oil and Natural Gas Properties.

Oil and natural gas properties are measured at fair value on a non-recurring basis using the income approach when assessing for impairment. Proved and unproved oil and natural gas properties are reviewed for impairment when events and circumstances indicate a possible decline in the recoverability of the carrying value of those properties. When assessing producing properties for impairment, the Partnership compares the expected undiscounted projected future cash flows of the producing properties to the carrying amount of the producing properties to determine recoverability. When the carrying amount exceeds its estimated undiscounted future cash flows, the carrying amount is written down to its fair value, which is measured as the present value of the projected future cash flows of such properties. The factors used to determine fair value include estimates of proved reserves, future commodity prices, timing of future production, operating costs, future capital expenditures, and a risk-adjusted discount rate. The Partnership estimated the fair value of the impaired properties for the three months ended March 31, 2020 using published forward commodity price curves as of the measurement date of March 31, 2020, considering locational and quality differentials based on a review of historical realizations. The following table presents information about the non-recurring fair value measurements of the impaired properties, including the applicable risk-adjusted discount rate utilized in the assessment:

The Partnership’s estimates of fair value have been determined at discrete points in time based on relevant market data. These estimates involve uncertainty, particularly in the current volatile market, and cannot be determined with precision. Changes to these estimates, particularly related to economic reserves, future commodity prices, and timing of future production could result in additional impairment charges in the future. There were no significant changes in valuation techniques or related inputs as of ~~June 30, 2019~~March 31, 2020 or December 31, ~~2018.~~

~~There were no assets measured at fair value on a non-recurring basis, after initial recognition, for the six months ended June 30, 2019 and 2018.~~

NOTE ~~7 —~~6 - CREDIT FACILITY

The Partnership maintains a senior secured revolving credit agreement, as amended (the “Credit Facility”). The Credit Facility has an aggregate maximum credit amount of $1.0 billion and terminates on November 1, 2022. The commitment of the lenders equals the lesser of the aggregate maximum credit amount and the borrowing base. The amount of the borrowing base is redetermined semi-annually, usually in October and April, and is derived from the value of the Partnership’s oil and natural gas properties as determined by the lender syndicate using pricing assumptions that often differ from the current market for future prices. The Partnership and the lenders (at the direction of two-thirds of the lenders) each have discretion to request a borrowing base redetermination one time between scheduled redeterminations. Effective ~~May 4, 2018,~~October 23, 2019 the borrowing base redetermination ~~increased~~reduced the borrowing base from ~~$550.0~~$675.0 million to ~~$600.0~~$650.0 million and, effective ~~October 31, 2018,~~May 1, 2020, the borrowing base was further ~~increased~~reduced to ~~$675.0 million, and effective May 15, 2019, the borrowing base was reaffirmed at $675.0~~$460.0 million.

Outstanding borrowings under the Credit Facility bear interest at a floating rate elected by the Partnership equal to an alternative base rate (which is equal to the greatest of the Prime Rate, the Federal Funds effective rate plus 0.50%, or 1-month LIBOR plus 1.00%) or LIBOR, in each case, plus the applicable margin. ~~Prior to October 31, 2018, the~~The applicable margin ~~ranged from 1.00% to 2.00% in the case of~~for the alternative base rate ranges from 0.75% to 1.75% and the applicable margin for LIBOR ranges from ~~2.00%~~1.75% to ~~3.00% in the case of LIBOR,~~2.75%, depending on the borrowings outstanding in relation to the borrowing base. ~~Effective October 31, 2018, the applicable margin for the alternative base rate was reduced to between 0.75% and 1.75% and the applicable margin for LIBOR was reduced to between 1.75% and 2.75%.~~

The weighted-average interest rate of the Credit Facility was ~~4.66%~~3.22% and ~~4.76%~~4.05% as of ~~June 30, 2019~~March 31, 2020 and December 31, ~~2018,~~2019, respectively. Accrued interest is payable at the end of each calendar quarter or at the end of each interest period, unless the interest period is longer than 90 days, in which case interest is payable at the end of every 90-day period. In addition, a commitment fee is payable at the end of each calendar quarter based on either a rate of 0.375% if the borrowing base utilization percentage is less than 50%, or 0.500% if the borrowing base utilization percentage is equal to or greater than 50%. The Credit Facility is secured by substantially all of the Partnership’s oil and natural gas production and assets.

The Credit Facility contains various limitations on future borrowings, leases, hedging, and sales of assets. Additionally, the Credit Facility requires the Partnership to maintain a current ratio of not less than 1.0:1.0 and a ratio of total debt to EBITDAX (Earnings before Interest, Taxes, Depreciation, Amortization, and Exploration) of not more than 3.5:1.0. As of ~~June 30, 2019,~~March 31, 2020, the Partnership was in compliance with all financial covenants in the Credit Facility.

The aggregate principal balance outstanding was ~~$436.0~~$388.0 million and ~~$410.0~~$394.0 million at ~~June 30, 2019~~March 31, 2020 and December 31, ~~2018,~~2019, respectively. The unused portion of the available borrowings under the Credit Facility were ~~$239.0~~$262.0 million and ~~$265.0~~$256.0 million at ~~June 30, 2019~~March 31, 2020 and December 31, ~~2018,~~2019, respectively.

NOTE ~~10 —~~9 - PREFERRED UNITS

~~Series A Redeemable Preferred Units~~

As of June 30, 2019 and December 31, 2018, there were no Series A redeemable preferred units outstanding. The Series A redeemable preferred units were entitled to an annual distribution of 10% of the outstanding funded capital of the Series A redeemable preferred units, payable on a quarterly basis in arrears.

The Series A redeemable preferred units were convertible into common and subordinated units at any time at the option of the Series A redeemable preferred unitholders. The Series A redeemable preferred units had an adjusted conversion price of $14.2683 and an adjusted conversion rate of 30.3431 common units and 39.7427 subordinated units per redeemable preferred unit.

The Series A redeemable preferred unitholders had the option to elect to have the Partnership redeem, at face value, all remaining Series A redeemable preferred units, effective as of December 31, 2017, plus any accrued and unpaid distributions. All Series A redeemable preferred units not redeemed by March 31, 2018 automatically converted to common and subordinated units effective as of January 1, 2018 or as soon as practicable thereafter.

For the six months ended June 30, 2018, 2,115 Series A redeemable preferred units were redeemed for $2.1 million, including accrued unpaid yield, and 24,248 Series A redeemable preferred units totaling $24.2 million were converted into 735,758 common units and 963,681 subordinated units as a result of the mandatory conversion subsequent to December 31, 2017.

Series B Cumulative Convertible Preferred Units

On November 28, 2017, the Partnership issued and sold in a private placement 14,711,219 Series B cumulative convertible preferred units representing limited partner interests in the Partnership for a cash purchase price of $20.3926 per Series B cumulative convertible preferred unit, resulting in total proceeds of approximately $300.0 million.

~~BLACK STONE MINERALS, L.P. AND SUBSIDIARIES~~

~~NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS~~

The Series B cumulative convertible preferred units are entitled to an annual distribution of 7%, payable on a quarterly basis in arrears. For the eight quarters consisting of the quarter in respect of which the initial distribution is paid and the seven full quarters thereafter, the quarterly distribution may be paid, at the sole option of the Partnership, (i) in-kind in the form of additional Series B cumulative convertible preferred units (the "Series B PIK Units"), (ii) in cash, or (iii) in a combination of Series B PIK Units and cash. Beginning with the ninth quarter, all Series B cumulative convertible preferred unit distributions shall be paid in cash. The number of Series B PIK Units to be issued, if any, shall equal the quotient of the Series B cumulative convertible preferred unit distribution amount (or portion thereof) divided by the Series B cumulative convertible preferred unit purchase price of $20.3926.

~~The Series B cumulative convertible preferred units are convertible into common units of the Partnership on November 29, 2019 and once per quarter thereafter. At such time, the~~ Series B cumulative convertible preferred units may be converted by each holder at its option, in whole or in part, into common units on a one-for-one basis at the purchase price of $20.3926, adjusted to give effect to any accrued but unpaid accumulated distributions on the applicable Series B cumulative convertible preferred units through the most recent declaration date. However, the Partnership shall not be obligated to honor any request for such conversion if such request does not involve an underlying value of common units of at least $10.0 million based on the closing trading price of common units on the trading day immediately preceding the conversion notice date, or such lesser amount to the extent such exercise covers all of a holder's Series B cumulative convertible preferred units.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

The Series B cumulative convertible preferred units had a carrying value of $298.4 million, including accrued distributions of $5.3 million, as of ~~June 30, 2019~~March 31, 2020 and December 31, ~~2018.~~2019. The Series B cumulative convertible preferred units are classified as mezzanine equity on the consolidated balance sheets since certain provisions of redemption are outside the control of the Partnership.

NOTE ~~11 —~~10 - EARNINGS PER UNIT

The Partnership applies the two-class method for purposes of calculating earnings per unit (“EPU”). The holders of the Partnership’s restricted common units have all the rights of a unitholder, including non-forfeitable distribution rights. As participating securities, the restricted common units are included in the calculation of basic earnings per unit. For the periods presented, the amount of earnings allocated to these participating units was not material.

Net income (loss) attributable to the Partnership is allocated to the Partnership’s general partner and the common and subordinated unitholders in proportion to their pro rata ownership after giving effect to distributions, if any, declared during the period.

The Partnership assesses the Series B cumulative convertible preferred units on an as-converted basis for the purpose of calculating diluted EPU. For the three months ended June 30, 2019, there were 15.0 million common units related to the Partnership's Series B cumulative convertible preferred units included in the calculation of diluted EPU. For the six months ended June 30, 2019 and the three and six months ended June 30, 2018, there were no common units related to the Partnership's Series B cumulative convertible preferred units included in the calculation of diluted EPU.

The Partnership’s restricted performance unit awards are contingently issuable units that are considered in the calculation of diluted EPU. The Partnership assesses the number of units that would be issuable, if any, under the terms of the arrangement if the end of the reporting period were the end of the contingency period. ~~For the three and six months ended June 30, 2019 and 2018, there were no units related to the Partnership’s restricted performance unit awards included in the calculation of diluted EPU.~~

NOTE ~~12 —~~11 - COMMON AND SUBORDINATED UNITS

Common and Subordinated Units

The common units and subordinated units represent limited partner interests in the Partnership. The partnership agreement restricts unitholders’ voting rights by providing that any units held by a person or group that owns 15% or more of any class of units then outstanding, other than the limited partners in Black Stone Minerals Company, L.P. prior to the initial public offering of BSM, their transferees, persons who acquired such units with the prior approval of the board of directors of the Partnership's general partner (the "Board"), holders of Series B cumulative convertible preferred units in connection with any vote, consent or approval of the Series B cumulative convertible preferred units as a separate class, and persons who own 15% or more of any class as a result of any redemption or purchase of any other person's units or similar action by the Partnership or any conversion of the Series B cumulative convertible preferred units at the Partnership's option or in connection with a change of control, may not vote on any matter.

~~Prior~~The holders of common units are and, prior to the end of the subordination period (as defined in the ~~Partnership~~partnership agreement), the ~~holders of common units and~~ subordinated units were, ~~each~~ entitled to participate in distributions and exercise the rights and privileges provided to limited partners holding common units and subordinated units, respectively, under the partnership agreement.

~~The partnership agreement generally provides that any distributions are paid each quarter in the following manner:~~

• ~~first, to the holders of the Series B cumulative convertible preferred units in an amount equal to 7% per annum, subject to certain adjustments;~~

• ~~second, to the holders of common units, until each common unit has received the applicable minimum quarterly distribution plus any arrearages from prior quarters; and~~

• ~~third, to the holders of subordinated units, until each subordinated unit has received the applicable minimum quarterly distribution.~~

If the distributions to common and subordinated unitholders exceeded the applicable minimum quarterly distribution per unit, then such excess amounts were distributed pro rata on the common and subordinated units as if they were a single class. In connection with the expiration of the subordination period, each outstanding subordinated unit converted into one common unit on May 24, 2019 and the priority right of the common unitholders ceased to exist.

Common Unit Repurchase Program

On November 5, 2018, the Board authorized the repurchase of up to $75.0 million in common units. The repurchase program authorizes the Partnership to make repurchases on a discretionary basis as determined by management, subject to market conditions, applicable legal requirements, available liquidity, and other appropriate factors. The Partnership ~~repurchased a total of 136,665 common units for an aggregate cost of $2.2 million~~made 0 repurchases under this program for the ~~six~~three months ended ~~June 30, 2019.~~March 31, 2020. As of ~~June 30, 2019,~~March 31, 2020, the Partnership has repurchased $4.2 million in common units under the repurchase program since inception. The repurchase program is funded from the Partnership's cash on hand or availability on the Credit Facility. Any repurchased units are canceled.

~~At-The-Market Offering Program~~

On May 26, 2017, the Partnership commenced an at-the-market offering program (the “ATM Program”) and in connection therewith entered into an Equity Distribution Agreement with Wells Fargo Securities, LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated, and UBS Securities LLC, as Sales Agents (each a “Sales Agent” and collectively the “Sales Agents”). Pursuant to the terms of the ATM Program, the Partnership may sell, from time to time through the Sales Agents, the Partnership’s common units representing limited partner interests having an aggregate offering amount of up to $100,000,000. Sales of common units, may be made in negotiated transactions or transactions that are deemed to be “at the market” offerings as defined in Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”), including sales made directly on the New York Stock Exchange or sales made to or through a market maker other than on an exchange.

Under the terms of the ATM Program, the Partnership may also sell common units to one or more of the Sales Agents as principal for its own account at a price to be agreed upon at the time of sale. Any sale of common units to a Sales Agent as principal would be pursuant to the terms of a separate agreement between the Partnership and such Sales Agent.

The Partnership intends to use the net proceeds from any sales pursuant to the ATM Program, after deducting the Sales Agents’ commissions and the Partnership’s offering expenses, for general partnership purposes, which may include, among other things, repayment of indebtedness outstanding under the Partnership’s Credit Facility.

Common units sold pursuant to the Equity Distribution Agreement are offered and sold pursuant to the Partnership’s existing effective shelf-registration statement on Form S-3 (File No. 333-215857), which was declared effective by the SEC on February 8, 2017.

The Equity Distribution Agreement contains customary representations, warranties and agreements, indemnification obligations, including for liabilities under the Securities Act, other obligations of the parties and termination provisions.

Overview

We are one of the largest owners and managers of oil and natural gas mineral interests in the United States. Our principal business is maximizing the value of our existing portfolio of mineral and royalty assets through active management and expanding our asset base through acquisitions of additional mineral and royalty interests. We maximize value through marketing our mineral assets for lease, creatively structuring the terms on those leases to encourage and accelerate drilling activity, and selectively participating alongside our lessees on a working interest basis. ~~Our primary business objective is~~We believe our large, diversified asset base and long-lived, non-cost-bearing mineral and royalty interests provide for stable to ~~grow our reserves,~~growing production and reserves over time, allowing the majority of generated cash ~~generated from operations over the long term, while paying,~~flow to ~~the extent practicable, a growing quarterly distribution~~be distributed to ~~our~~ unitholders.

As of ~~June 30, 2019,~~March 31, 2020, our mineral and royalty interests were located in 41 states in the continental United States, including all of the major onshore producing basins. These non-cost-bearing interests include ownership in ~~over 60,000~~approximately 69,000 producing wells. We also own non-operated working interests, a significant portion of which are on our positions where we also have a mineral and royalty interest. We recognize oil and natural gas revenue from our mineral and royalty and non-operated working interests in producing wells when control of the oil and natural gas produced is transferred to the customer and collectability of the sales price is reasonably assured. Our other sources of revenue include mineral lease bonus and delay rentals, which are recognized as revenue according to the terms of the lease agreements.

Recent Developments

~~Acquisitions~~COVID-19 Pandemic and Commodity Prices

InThe COVID-19 pandemic has adversely affected the ~~first half of 2019, we acquired mineral~~global economy, disrupted global supply chains and ~~royalty interests primarily~~created significant volatility in the ~~Permian Basin~~financial markets. In addition, the pandemic has resulted in travel restrictions, business closures and the institution of quarantining and other restrictions on movement in ~~East Texas~~many communities. To protect the health and well-being of our workforce in the wake of COVID-19, we have implemented remote work arrangements for ~~aggregate consideration~~all employees. We do not expect these arrangements to impact our ability to maintain operations.

The impact of ~~$40.7 million~~the COVID-19 pandemic and geopolitical events that increased the supply of low-priced oil have also negatively affected the oil and natural gas business environment, significantly reducing prices of oil, natural gas, and natural gas liquids ("NGLs"). While we use derivative instruments to partially mitigate the impact of commodity price volatility, our revenues and operating results depend significantly upon the prevailing prices for oil and natural gas. The current price environment has caused some of our operators' wells to become uneconomic, which has resulted, or may result in ~~cash~~the future, in suspension of production from those wells or a significant reduction in or no royalty revenues from existing production. Some operators may also attempt to shut in producing wells and ~~$0.9 million~~avoid lease termination or payment of shut-in royalties by claiming force majeure, if provided for in ~~our common units. Additional information regarding acquisitions is contained in Note 4 – Oil~~the applicable lease. Because these shut-ins have happened so recently, and ~~Natural Gas Properties~~no operator has, to our ~~unaudited interim consolidated financial statements included elsewhere in this Quarterly Report~~knowledge claimed force majeure, we have not been able to quantify their impact on ~~Form 10-Q.~~our future revenues.

~~End~~The current price environment also caused us to determine that certain depletable units consisting of mature oil producing properties were impaired. Therefore, we recognized impairment of oil and natural gas properties of $51.0 million for three months ended March 31, 2020. Additionally, the borrowing base under the Credit Facility, which takes into consideration the estimated loan value of our oil and natural gas properties, was reduced from $650.0 million to $460.0 million, effective May 1, 2020. In a prolonged period of low commodity prices, we may be required to impair additional properties and the borrowing base under our credit facility could be further reduced. In light of the ~~Subordination Period~~

~~The subordination period under the partnership agreement ended on the first~~challenging business ~~day after we earned~~environment and ~~paid an aggregate amount of at least $1.35 (the annualized minimum quarterly distribution applicable for quarterly periods ending March 31, 2019 and thereafter) multiplied~~uncertainty caused by the ~~total number~~pandemic, the board of ~~outstanding common and subordinated units for~~directors of our general partner (the "Board") also approved a ~~period of four consecutive, non-overlapping quarters ending on or after March 31, 2019, and there were no outstanding arrearages on~~reduction in the ~~common units.

Accordingly,~~2020 to increase the amount of retained free cash flow for debt reduction and balance sheet protection.

Shelby Trough Update

On May 4, 2020, we entered into a development agreement with affiliates of Aethon Energy ("Aethon") with respect to our ~~96,328,836 subordinated units converted into 96,328,836 common units on May 24, 2019~~undeveloped Shelby Trough Haynesville and ~~common units are no longer entitled~~Bossier shale acreage in Angelina County, Texas. The agreement provides for minimum well commitments by Aethon in exchange for reduced royalty rates and exclusive access to ~~arrearages.~~our mineral and leasehold acreage in the contract area. The agreement calls for a minimum of four wells to be drilled in the initial program year, which begins in the third quarter of 2020, increasing to a minimum of 15 wells per year beginning with the third program year.

Common Unit Repurchase Program

On November 5, 2018, the Board authorized the repurchase of up to $75.0 million in common units. The repurchase program authorizes us to make repurchases on a discretionary basis as determined by management, subject to market conditions, applicable legal requirements, available liquidity, and other appropriate factors. ~~We have repurchased~~All or a ~~total~~portion of

~~136,665~~ any repurchases may be made under a Rule 10b5-1 plan, which would permit common units ~~for an aggregate cost~~to be purchased when we might otherwise be precluded from doing so under applicable laws. The repurchase program does not obligate us to acquire any particular amount of ~~$2.2 million~~common units and may be modified or suspended at any time and could be terminated prior to completion. We will periodically report the number of common units repurchased. We made no repurchases under this program for the ~~six~~three months ended ~~June 30, 2019.~~March 31, 2020. As of March 31, 2020, we have repurchased $4.2 million in common units under the repurchase program since inception. The repurchase program is funded from our cash on hand or availability onunder the Credit Facility. Any repurchased units are canceled.

~~Shelby Trough Update~~

We expect drilling activity to slow temporarily on our Shelby Trough acreage in East Texas, in part due to the current natural gas price environment. XTO Energy Inc. has informed us that it intends to complete previously drilled wells and, due to constraints in gathering and treating capacity, will pause new drilling activity in the area until the third quarter of 2020. In addition, BPX Energy (“BPX”) recently decided to limit its Shelby Trough drilling activity to a specific area encompassing approximately 17,000 gross acres. Under the terms of our development agreement with BPX, which requires continuous drilling activity to hold acreage, BPX has released over 100,000 gross acres. Much of this area has been delineated through BPX’s drilling to date with successful wells in both the Haynesville and Bossier shales, and we intend to place it with another operator or operators.

Business Environment

The information ~~presented~~ below is designed to give a broad overview of the oil and natural gas business environment as it affects us.

COVID-19 Pandemic and Market Conditions

The COVID-19 pandemic and related economic repercussions have resulted in a significant reduction in demand for and prices of oil, natural gas and NGLs. The effect of this was amplified late in the quarter when the Organization of Petroleum Exporting Countries and its broader partners ("OPEC+") were unable to reach an agreement on production levels for oil, at which point Saudi Arabia and Russia initiated efforts to aggressively increase production. While OPEC+ agreed in April 2020 to cut production, downward pressure on commodity prices has remained and could continue for the foreseeable future. In addition, concerns over the saturation of storage capacity for oil has further depressed prices.We expect these market conditions to result in a decline in drilling activity as operators revise their capital budgets downward and adjust their operations, including shutting in currently producing wells, in response to lower commodity prices. Given the dynamic nature of these events, we cannot reasonably estimate the period of time that the COVID-19 pandemic and related market conditions will persist.

Commodity Prices and Demand

Oil and natural gas prices have been historically volatile based upon the dynamics of supply and demand. The U.S. Energy Information Administration ("EIA") forecasts that the WTI spot oil price will average $59.58 per Bbl in 2019 and $63.00 per Bbl in 2020 and that the Henry Hub spot natural gas prices will average $2.62 per MMBtu in 2019 and $2.77 per MMBtu in 2020.

To manage the variability in cash flows associated with the projected sale of our oil and natural gas production, we use various derivative instruments, which have recently consisted of fixed-price swap contracts and costless collar contracts.

The following table reflects commodity prices ~~at the end~~as of each ~~quarter~~date presented:

As we are not the operator of record on any producing properties, drilling on our acreage is dependent upon the exploration and production companies that lease our acreage. In addition to drilling plans that we seek from our operators, we also monitor rig counts in an effort to identify existing and future leasing and drilling activity on our acreage.

Natural Gas Storage

A substantial portion of our revenue is derived from sales of oil production attributable to our interests; however, the

majority of our production is natural gas. Natural gas prices are significantly influenced by storage levels throughout the year. Accordingly, we monitor the natural gas storage reports regularly in the evaluation of our business and its outlook.

Historically, natural gas supply and demand fluctuates on a seasonal basis. From April to October, when the weather is warmer and natural gas demand is lower, natural gas storage levels generally increase. From November to March, storage levels typically decline as utility companies draw natural gas from storage to meet increased heating demand due to colder weather. In order to maintain sufficient storage levels for increased seasonal demand, a portion of natural gas production during the summer months must be used for storage injection. The portion of production used for storage varies from year to year depending on the demand from the previous winter and the demand for electricity used for cooling during the summer months. ~~Based on a forecast of relatively normal U.S. temperatures in the third quarter and a forecast of growing~~The EIA estimates that natural gas ~~production,~~inventories concluded the ~~EIA expects that U.S. inventories will reach 3.8 trillion cubic feet~~withdrawal season on March 31, 2020 at ~~the end of October, which would be~~almost 2.0 Tcf, or 17% higher than ~~October 2018 levels and 2% higher than~~ the previous five-year average.

How We Evaluate Our Operations

We use a variety of operational and financial measures to assess our performance. Among the measures considered by management are the following:

•volumes of oil and natural gas produced;

•commodity prices including the effect of derivative instruments; and

•Adjusted EBITDA and Distributable cash flow.

Volumes of Oil and Natural Gas Produced

In order to track and assess the performance of our assets, we monitor and analyze our production volumes from the various basins and plays that constitute our extensive asset base. We also regularly compare projected volumes to actual reported volumes and investigate unexpected variances.

Commodity Prices

Factors Affecting the Sales Price of Oil and Natural Gas

The prices we receive for oil, natural gas, and ~~natural gas liquids (“NGLs”)~~NGLs vary by geographical area. The relative prices of these products are determined by the factors affecting global and regional supply and demand dynamics, such as economic conditions, production levels, availability of transportation, weather cycles, and other factors. In addition, realized prices are influenced by product quality and proximity to consuming and refining markets. Any differences between realized prices and New York Mercantile Exchange ("NYMEX") prices are referred to as differentials. All our production is derived from properties located in the United States.


•	~~Oil~~. The substantial majority of our oil production is sold at prevailing market prices, which fluctuate in response to many factors that are outside of our control. NYMEX light sweet crude oil, commonly referred to as West Texas

•Oil. The substantial majority of our oil production is sold at prevailing market prices, which fluctuate in response to many factors that are outside of our control. NYMEX light sweet crude oil, commonly referred to as West Texas Intermediate ("WTI"), is the prevailing domestic oil pricing index. The majority of our oil production is priced at the prevailing market price with the final realized price affected by both quality and location differentials.

The chemical composition of oil plays an important role in its refining and subsequent sale as petroleum products. As a result, variations in chemical composition relative to the benchmark oil, usually WTI, will result in price adjustments, which are often referred to as quality differentials. The characteristics that most significantly affect quality differentials include the density of the oil, as characterized by its American Petroleum Institute (“API”) gravity, and the presence and concentration of impurities, such as sulfur.

Location differentials generally result from transportation costs based on the produced oil’s proximity to consuming and refining markets and major trading points.


•	•Natural Gas. The NYMEX price quoted at Henry Hub is a widely used benchmark for the pricing of natural gas in the United States. The actual volumetric prices realized from the sale of natural gas differ from the quoted NYMEX price as a result of quality and location differentials.

Quality differentials result from the heating value of natural gas measured in Btus and the presence of impurities, such as hydrogen sulfide, carbon dioxide, and nitrogen. Natural gas containing ethane and heavier hydrocarbons has a higher Btu value and will realize a higher volumetric price than natural gas which is predominantly methane, which has a lower Btu value. Natural gas with a higher concentration of impurities will realize a lower volumetric price due to the presence of the impurities in the natural gas when sold or the cost of treating the natural gas to meet pipeline quality specifications.

Natural gas, which currently has a limited global transportation system, is subject to price variances based on local supply and demand conditions and the cost to transport natural gas to end user markets.

Hedging

We enter into derivative instruments to partially mitigate the impact of commodity price volatility on our cash generated from operations. From time to time, such instruments may include variable-to-fixed-price swaps, fixed-price contracts, costless collars, and other contractual arrangements. The impact of these derivative instruments could affect the amount of revenue we ultimately realize.

Our open derivative contracts consist of fixed-price swap contracts and costless collar contracts. Under fixed-price swap contracts, a counterparty is required to make a payment to us if the settlement price is less than the swap strike price. Conversely, we are required to make a payment to the counterparty if the settlement price is greater than the swap strike price. Our costless collar contracts contain a fixed floor price and a fixed ceiling price. If the market price exceeds the fixed ceiling price, we ~~receive~~pay the difference between the fixed ceiling price ~~from~~and the ~~counterparty and we pay the~~ market settlement price. If the market price is below the fixed floor price, we receive the ~~fixed floor~~difference between the market settlement price and ~~we pay~~ the ~~market~~fixed floor price. If the market price is between the fixed floor and fixed ceiling price, no payments are due from either party. If we have multiple contracts outstanding with a single counterparty, unless restricted by our agreement, we will net settle the contract payments.

We may employ contractual arrangements other than fixed-price swap contracts and costless collar contracts in the future to mitigate the impact of price fluctuations. If commodity prices decline in the future, our hedging contracts will partially mitigate the effect of lower prices on our future revenue. Our open oil and natural gas derivative contracts as of ~~June 30, 2019~~March 31, 2020 are detailed in Note ~~5 –~~4 - Commodity Derivative Financial Instruments to our unaudited consolidated financial statements included elsewhere in this Quarterly ~~Report on Form 10-Q.~~Report.

Pursuant to the terms of our Credit Facility, we are allowed to hedge certain percentages of expected future monthly production volumes equal to the lesser of (i) internally forecasted production and (ii) the average of reported production for the most recent three months.

We are allowed to hedge up to 90% of such volumes for the first 24 months, 70% for months 25 through 36, and 50% for months 37 through 48. As of ~~June 30, 2019,~~March 31, 2020, we have hedged 91% ~~and 72%~~ of our available oil and condensate hedge volumes ~~for 2019~~ and ~~2020, respectively. Also, we have hedged 86% and 50%~~75% of our available natural gas hedge volumes for ~~2019 and 2020, respectively.~~

2020.

We intend to continuously monitor the production from our assets and the commodity price environment, and will, from time to time, add additional hedges within the percentages described above related to such production for the following 12 to 30 months. We do not enter into derivative instruments for speculative purposes.

Non-GAAP Financial Measures

Adjusted EBITDA and Distributable cash flow are supplemental non-GAAP financial measures used by our management and external users of our financial statements such as investors, research analysts, and others, to assess the financial performance of our assets and our ability to sustain distributions over the long term without regard to financing methods, capital structure, or historical cost basis.

We define Adjusted EBITDA as net income (loss) before interest expense, income taxes, and depreciation, depletion, and amortization adjusted for impairment of oil and natural gas properties, accretion of asset retirement obligations, unrealized gains and losses on commodity derivative instruments, and non-cash equity-based compensation. We define Distributable cash flow as Adjusted EBITDA plus or minus amounts for certain non-cash operating activities, estimated replacement capital expenditures during the subordination period, cash interest expense, ~~and~~ distributions to ~~noncontrolling interests~~preferred unitholders, and ~~preferred unitholders.~~restructuring charges.

Adjusted EBITDA and Distributable cash flow should not be considered an alternative to, or more meaningful than, net income (loss), income (loss) from operations, cash flows from operating activities, or any other measure of financial performance presented in accordance with ~~GAAP~~generally accepted accounting principles ("GAAP") in the United States as measures of our financial performance.

Adjusted EBITDA and Distributable cash flow have important limitations as analytical tools because they exclude some but not all items that affect net income (loss), the most directly comparable GAAP financial measure. Our computation of Adjusted EBITDA and Distributable cash flow may differ from computations of similarly titled measures of other companies.

The following table presents a reconciliation of net income (loss), the most directly comparable GAAP financial measure, to Adjusted EBITDA and Distributable cash flow for the periods indicated:

Revenue

Total revenue for the quarter ended ~~June 30, 2019~~March 31, 2020 increased compared to the quarter ended ~~June 30, 2018.~~March 31, 2019. The increase in total revenue ~~was~~from the corresponding period is primarily due to a gain on our commodity derivative instruments in the ~~current~~first quarter of 2020, compared to a loss in the ~~second~~first quarter of ~~2018.~~2019. The overall increase in total revenue was partially offset by ~~decreases~~a decrease in ~~lease bonus and other income,~~ oil and condensate sales and natural gas and ~~natural gas liquids sales.~~NGL sales as a result of lower realized commodity prices and a decrease in lease bonus and other income.

Oil and condensate sales. Oil and condensate sales ~~during~~decreased for the ~~current~~ quarter ~~were lower than~~ended March 31, 2020 as compared to the ~~second quarter of 2018~~corresponding period in 2019 due to lower realized commodity prices, partially offset by higher production volumes. Our

mineral and royalty interest oil and condensate volumes increased ~~15%~~4% in the ~~second~~first quarter of ~~2019~~2020 relative to the corresponding period in ~~2018~~2019, primarily driven by production increases in the Permian Basin. Our mineral and royalty interest oil and condensate volumes accounted for ~~93%and 90%~~92% of total oil and condensate volumes for the quarters ended ~~June 30, 2019~~March 31, 2020 and ~~2018, respectively.~~2019.

Gain (loss) on commodity derivative instruments. During the ~~second~~first quarter of ~~2019,~~2020, we recognized a gain from our commodity derivative instruments compared to a loss in the same period in ~~2018.~~2019. Cash settlements we receive represent realized gains, while cash settlements we pay represent realized losses related to our commodity derivative instruments. In addition to cash settlements, we also recognize fair value changes on our commodity derivative instruments in each reporting period. The changes in fair value result from new positions and settlements that may occur during each reporting period, as well as the relationships between contract prices and the associated forward curves. The change in gain (loss) on commodity derivative instruments between the comparative periods is primarily due to an increase in the fair value of our oil and natural gas commodity contracts in the second quarter of 2019 compared to a decrease in fair value in the same period in 2018. For the three months ended ~~June 30, 2019,~~March 31, 2020, we recognized ~~$26.3~~$9.0 million of realized gains and $81.1 million of unrealized gains from our oil and natural gas commodity contracts, compared to ~~$27.1~~$1.7 million of realized gains and $42.9 million of unrealized losses in the same period in ~~2018.~~2019. The unrealized gains on our commodity contracts during the first quarter of 2020 and the unrealized losses in the same period in 2019 were primarily driven by changes in the forward commodity price curves for oil during each period.

Lease bonus and other income. When we lease our mineral interests, we generally receive an upfront cash payment, or a lease bonus. Lease bonus ~~income~~revenue can vary substantively between periods because it is derived from individual transactions with operators, some of which may be significant. Lease bonus and other income for the ~~second~~first quarter of ~~2019~~2020 was lower than the same period in ~~2018.~~2019. Leasing activity in the Permian Basin, Green River Basin, and ~~the Wilcox trend~~Bakken/Three Forks made up the majority of lease bonus revenue in the ~~second~~first quarter of ~~2019,~~2020, while a substantial portion of ~~second~~first quarter ~~2018~~2019 activity came from the Permian Basin, ~~as well as the Austin Chalk, Bakken/Three Forks,~~Woodbine, and ~~Haynesville/Bossier trends.~~Haynesville Shale.

Operating ~~and Other~~ Expenses

Lease operating expense. Lease operating expense includes recurring expenses associated with our non-operated working interests necessary to produce hydrocarbons from our oil and natural gas wells, as well as certain nonrecurring expenses, such as well repairs. Lease operating expense decreased for the quarter ended ~~June 30, 2019~~March 31, 2020 as compared to the same period in ~~2018,~~2019, primarily due to lower nonrecurring service-related expenses, including workovers, on wells in which we own a non-operating working interest.

Production costs and ad valorem taxes. Production taxes include statutory amounts deducted from our production revenues by various state taxing entities. Depending on the regulations of the states where the production originates, these taxes may be based on a percentage of the realized value or a fixed amount per production unit. This category also includes the costs to process and transport our production to applicable sales points. Ad valorem taxes are jurisdictional taxes levied on the value of oil and natural gas minerals and reserves. Rates, methods of calculating property values, and timing of payments vary between taxing authorities. For the quarter ended ~~June 30, 2019,~~March 31, 2020, production costs and ad valorem taxes ~~increased~~decreased as compared to the quarter ended ~~June 30, 2018,~~March 31, 2019, primarily as a result of ~~increased oil and natural gas production volumes partially offset by~~ lower commodity prices.

Exploration expense. Exploration expense typically consists of dry-hole expenses, delay rentals, and geological and geophysical costs, including seismic costs, and is expensed as incurred under the successful efforts method of accounting. Exploration expense was minimal for each of the three months ended ~~June 30, 2019 primarily consisted of costs incurred to acquire 3-D seismic information related to our mineral~~March 31, 2020 and ~~royalty interests from a third-party service provider. Exploration expense for the three months ended June 30, 2018 primarily related to the costs incurred on the Pepperjack B#1 well.~~2019.

Depreciation, depletion, and amortization. Depletion is ~~an estimate of~~ the amount of cost basis of oil and natural gas properties attributable to the volume of hydrocarbons extracted during a period, calculated on a units-of-production basis. Estimates of proved developed producing reserves are a major component of the calculation of depletion. We adjust our depletion rates semi-annually based upon mid-year and year-end reserve reports, except when circumstances indicate that there has been a significant change in reserves or costs. Depreciation, depletion, and amortization decreased for the quarter ended ~~June 30, 2019~~March 31, 2020 as compared to the same period in ~~2018,~~2019, primarily due to a reduction in cost basis with a lower corresponding reduction in proved developed producing reserve quantities. The reduction in cost basis is primarily due to depreciation, depletion, and amortization recorded during the ~~impact~~prior twelve months.

Impairment of oil and natural gas properties. Individual categories of oil and natural gas properties are assessed periodically to determine if the net book value for these properties has been impaired. Management periodically conducts an in-depth evaluation of the cost of property acquisitions, successful exploratory wells, development activity, unproved leasehold, and mineral interests to identify impairments. Impairments totaled $51.0 million for the quarter ended March 31, 2020 primarily

due to declines in future expected realizable net cash flows as a result of lower ~~depletion rates partially offset by higher production.~~commodity prices as of March 31, 2020. There were no impairments for the quarter ended March 31, 2019.

General and administrative. General and administrative expenses are costs not directly associated with the production of oil and natural gas and include expenses such as the cost of employee salaries and related benefits, office expenses, and fees for professional services. For the quarter ended ~~June 30, 2019,~~March 31, 2020, general and administrative expenses decreased as compared to the same period in ~~2018,~~2019, primarily due to lower costs associated with our incentive compensation ~~plans~~plans. This change was driven by a$4.7 million of downward cost revisions recognized in the first quarter of 2020 for performance-based incentive awards due to the decrease in our common unit price period over ~~period.~~period compared with $5.6 million of costs recognized for performance-based incentive awards in the first quarter of 2019. Incentive compensation costs in the first quarter of 2019 also included incentive compensation awarded in connection with our initial public offering. The overall decrease was partially offset by $4.8 million of restructuring charges associated with broad workforce reductions in the first quarter of 2020.

Interest expense. Interest expense was ~~higher~~lower in the ~~second~~first quarter of 2019 primarily due to increased borrowings under our Credit Facility. Average outstanding borrowings during the second quarter of 2019 were higher than the second quarter of 2018 due to the funding of acquisitions in 2019 and 2018.

~~Revenue~~

Total revenue for the six months ended June 30, 2019 increased compared to the six months ended June 30, 2018. The increase in total revenue from the corresponding prior period is primarily due to a decreased loss from our commodity derivative instruments and increased natural gas and natural gas liquids sales. The overall increase in total revenue was partially offset by decreases in oil and condensate sales and lease bonus and other income.

~~Oil and condensate sales.~~ Oil and condensate sales during the six months ended June 30, 2019 were lower than the six months ended June 30, 2018 primarily due to lower realized commodity prices partially offset by increased production volumes. Our~~mineral and royalty interest oiland condensatevolumes increased 6%~~in~~the six months ended June 30, 2019~~2020 relative to the corresponding period in ~~2018~~, ~~primarily driven by production increasesin the Permian Basin. Our mineral and royalty interest oil and condensate volumes accountedfor 93%and 90%of total oil and condensate volumes for thesix months ended June 30,~~ 2019,~~and2018, respectively.~~

~~Natural gas and natural gas liquids sales.~~ Natural gas and NGL sales during the six months ended June 30, 2019 were higher than the six months ended June 30, 2018 due to increased production volumes, largely in the Haynesville/Bossier play, as well as in the Permian Basin, partially offset by lower realized commodity prices. Mineral and royalty interest production accounted for 67% and 59% of our natural gas volumes for the six months ended June 30, 2019 and 2018, respectively.

~~Gain (loss) on commodity derivative instruments.~~ During the six months ended June 30, 2019, we recognized a decreased loss from our commodity derivative instruments compared to the same period in 2018. The decreased loss from our commodity derivative instruments is primarily due to a lower net decrease in the fair value of our oil and natural gas commodity contracts in the second quarter of 2019 compared to the corresponding prior period. In the six months ended June 30, 2019 we recognized $16.7 million of unrealized losses from our oil and natural gas commodity contracts, compared to $39.0 million of unrealized losses in the same period in 2018.

~~Lease bonus and other income.~~ Lease bonus and other income for the six months ended June 30, 2019 was lower than the same period in 2018. Leasing activity in the Permian Basin, as well as the Bakken/Three Forks, Wilcox, and Woodbine trends made up the majority of lease bonus revenue in the six months ended June 30, 2019, while a substantial portion of the activity in the corresponding prior period came from the Permian Basin, as well as the Canyon Lime, Cherry Canyon, Douglas, Eagle Ford, and Frio trends.

~~Operating and Other Expenses~~

~~Lease operating expense~~. Lease operating expense increased for the six months ended June 30, 2019 as compared to the same period in 2018, primarily due to higher nonrecurring service-related expenses, including workovers, on wells in which we own a non-operating working interest.

~~Production costs and ad valorem taxes~~. For the six months ended June 30, 2019, production costs and ad valorem taxes decreased as compared to the six months ended June 30, 2018, as a result of tax credits received during the period and lower commodity prices, partially offset by increased oil and natural gas production volumes.

~~Exploration expense~~. Exploration expense for the six months ended June 30, 2019 primarily consisted of costs incurred to acquire 3-D seismic information related to our mineral and royalty interests from a third-party service provider. Exploration expense for the six months ended June 30, 2018 primarily related to the costs incurred on the Pepperjack B#1 well.

~~Depreciation, depletion, and amortization~~. Depreciation, depletion, and amortization decreased for the six months ended June 30, 2019 as compared to the same period in 2018, primarily due to the impact of lower depletion rates partially offset by higher production.

~~General and administrative. For the six months ended June 30, 2019, general and administrative expenses decreased as compared to the same period in2018, primarily~~ due to lower ~~costs associated with our incentive compensation plans driven by a decrease in our common unit price period over period.~~

~~Interest expense. Interest expense was higher in the six months ended June 30, 2019 primarily due to increased~~interest rates and lower average outstanding borrowings under our Credit Facility. ~~Average outstanding borrowings during the six months ended June 30, 2019 were higher than the six months ended June 30, 2018 due to the funding of acquisitions in 2019 and 2018.~~

Liquidity and Capital Resources

Overview

Our primary sources of liquidity are cash generated from operations, borrowings under our Credit Facility, and proceeds from the issuance of equity and debt. Our primary uses of cash are for distributions to our unitholders, reducing outstanding borrowings under our Credit Facility, and for investing in our business, specifically the acquisition of mineral and royalty interests and our selective participation on a non-operated working interest basis in the development of our oil and natural gas properties. As of March 31, 2020, we had outstanding borrowings of $388.0 million under the Credit Facility, and on May 1, 2020, the borrowing base under our Credit Facility was reduced to $460.0 million.

The Board has adopted a policy pursuant to which, at a minimum, distributions will be paid on each common unit for each quarter to the extent we have sufficient cash generated from our operations after establishment of cash reserves, if any, and after we have made the required distributions to the holders of our outstanding preferred units. However, we do not have a legal or contractual obligation to pay distributions on our common units quarterly or on any other basis, and there is no guarantee that we will pay distributions to our common unitholders in any quarter. The Board may change the foregoing distribution policy at any time and from time to time. In light of the challenging business environment and uncertainty caused by the pandemic, the Board approved a reduction in the quarterly distribution for the first quarter of 2020 to increase the amount of retained free cash flow for debt reduction and balance sheet protection. If our borrowings exceed our borrowing base, our ability to pay cash distributions to our unitholders will be limited.

We intend to finance our future acquisitions with cash generated from operations, borrowings from our Credit Facility, and proceeds from any future issuances of equity and debt. Over the long-term, we intend to finance our working interest capital needs with our executed farmout agreements and internally-generated cash flows, although at times we may fund a portion of these expenditures through other financing sources such as borrowings under our Credit Facility. Replacement capital expenditures are expenditures necessary to replace our existing oil and natural gas reserves or otherwise maintain our asset base over the long-term. ~~Prior to the end of the subordination period, we were required by our partnership agreement to retain cash from our operations in an amount equal to our estimated replacement capital requirements.~~ The Board established a replacement capital expenditure estimate of ~~$13.0 million for the period of April 1, 2017 to March 31, 2018, and~~ $11.0 million for the period of April 1, 2018 to March 31, 2019. NoDue to the expiration of the subordination period, we do not intend to establish a replacement capital expenditure estimate ~~will be established~~ for periods subsequent to March 31, 2019.

Cash flows used in financing activities (156,471 ) (83,638 ) (72,833 )

Operating Activities. Our operating cash flows are dependent, in large part, on our production, realized commodity prices, derivative settlements, lease bonus revenue, and operating expenses. Cash flows provided by operating activities decreased in the first quarter of 2020 as compared to the same period of 2019. The ~~increase in cash flows from operations~~decrease was primarily due to ~~a net increase in cash flows from changes in operating assets~~decreased oil and ~~liabilities~~condensate sales and natural gas and NGL sales driven by lower realized commodity prices for the ~~six~~three months ended ~~June 30, 2019~~March 31, 2020 compared to ~~a net decrease for~~ the same period of ~~2018 and~~2019. The overall decrease was partially offset by higher net cash received on settlement of commodity derivative ~~instruments for the six months ended June 30, 2019 compared to cash paid for the same period of 2018.~~instruments.

Investing Activities. Net cash was provided by investing activities in the first quarter of 2020 as compared to net cash used in investing activities ~~decreased~~ in the ~~first six months~~same period of ~~2019 as compared to the corresponding period in 2018.~~2019. The ~~decrease~~change was primarily due to reduced oil and natural gas property acquisitions and expenditures and ~~higher~~the receipt of proceeds ~~received~~ from ~~our farmout agreements.~~the sale of oil and natural gas properties in the first quarter of 2020.

The increase was primarily due to ~~increased~~net repayments under our Credit Facility in the first quarter of 2020 as compared to net borrowings in the first quarter of 2019. The overall increase was partially offset by lower distributions to common and subordinated unitholders ~~increased~~and decreased repurchases of common ~~units, and decreased net borrowings under our Credit Facility.~~units.

Development Capital Expenditures

Our ~~2019~~2020 total development capital expenditure budget associated with our non-operated working interests is expected to be approximately ~~$10.0~~$5.0 million, net of farmout reimbursements, of which ~~$3.5 million~~a nominal amount has been invested in the ~~six~~three months ended ~~June 30, 2019.~~March 31, 2020. The majority of this capital will be spent for workovers on existing wells in which we own a working ~~interest or for acquiring new leasehold acreage for subsequent farmout in the Haynesville/Bossier play.~~interest.

~~Acquisitions~~

We spent approximately $40.7 million and issued common units valued at $0.9 million during the six months ended June 30, 2019 related to acquisitions of mineral and royalty interests, which also included proved oil and natural gas properties. See Note 4 – Oil and Natural Gas Properties to our unaudited interim consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q for further discussion.

Credit Facility

Pursuant to our $1.0 billion ~~Credit Facility,~~senior secured revolving credit agreement, as amended (the “Credit Facility”), the commitment of the lenders equals the lesser of the aggregate maximum credit amounts of the lenders and the borrowing base, which is determined based on the lenders’ estimated value of our oil and natural gas properties. Borrowings under the Credit Facility may be used for the acquisition of properties, cash distributions, and other general corporate purposes. Effective May 4, 2018, the borrowing base redetermination increased the borrowing base to $600.0 million, effective October 31, 2018, the borrowing base was further increased to $675.0 million, and effective May 15, 2019, the borrowing base was reaffirmed at $675.0 million. Our Credit Facility terminates on November 1, 2022. As of ~~June 30, 2019,~~March 31, 2020, we had outstanding borrowings of ~~$436.0~~$388.0 million at a weighted-average interest rate of ~~4.66%~~3.22%.

The borrowing base is redetermined semi-annually, typically in April and October of each year, by the administrative agent, taking into consideration the estimated loan value of our oil and natural gas properties consistent with the administrative agent’s normal lending criteria. The administrative agent’s proposed redetermined borrowing base must be approved by all lenders to increase our existing borrowing base, and by two-thirds of the lenders to maintain or decrease our existing borrowing base. In addition, we and the lenders (at the ~~election~~direction of two-thirds of the lenders) each have discretion to ~~have the~~request a borrowing base ~~redetermined once~~redetermination one time between scheduled redeterminations. We also have the right to request a redetermination following acquisition of oil and natural gas properties in excess of 10% of the value of the borrowing base immediately prior to such acquisition. Effective October 23, 2019 the borrowing base redetermination reduced the borrowing base from $675.0 million to $650.0 million and, effective May 1, 2020, the borrowing base was further reduced to $460.0 million.

Outstanding borrowings under the Credit Facility bear interest at a floating rate elected by us equal to an alternative base rate (which is equal to the greatest of the Prime Rate, the Federal Funds effective rate plus 0.50%, or 1-month LIBOR plus 1.00%) or LIBOR, in each case, plus the applicable margin. ~~Prior to October 31, 2018, the~~The applicable margin ~~ranged from 1.00% to 2.00% in the case of~~for the alternative base rate ranges from 0.75% to 1.75% and the applicable margin for LIBOR ranges from ~~2.00%~~1.75% to ~~3.00% in the case of LIBOR,~~2.75%, depending on the borrowings outstanding in relation to the borrowing base. ~~Effective October 31, 2018, the applicable margin for the alternative base rate was reduced to between 0.75% and 1.75% and the applicable margin for LIBOR was reduced to between 1.75% and 2.75%.~~

We are obligated to pay a quarterly commitment fee ranging from a 0.375% to 0.500% annualized rate on the unused portion of the borrowing base, depending on the amount of the borrowings outstanding in relation to the borrowing base. Principal may be optionally repaid from time to time without premium or penalty, other than customary LIBOR breakage, and is required to be paid (a) if the amount outstanding exceeds the borrowing base, whether due to a borrowing base redetermination or otherwise, in some cases subject to a cure period, or (b) at the maturity date. Our Credit Facility is secured by substantially all of our oil and natural gas production and assets.

Our credit agreement contains various affirmative, negative, and financial maintenance covenants. These covenants, among other things, limit additional indebtedness, additional liens, sales of assets, mergers and consolidations, dividends and distributions, transactions with affiliates, and entering into certain derivative agreements, as well as require the maintenance of

certain financial ratios. The credit agreement contains two financial covenants: total debt to EBITDAX of 3.5:1.0 or less and a current ratio of 1.0:1.0 or greater as defined in the credit agreement. Distributions are not permitted if there is a default under the credit agreement (including ~~due to a~~the failure to satisfy one of the financial covenants) or during any time that our borrowing base is lower than the loans outstanding under the credit agreement. The lenders have the right to accelerate all of the indebtedness under the credit agreement upon the occurrence and during the continuance of any event of default, and the credit agreement contains customary events of default, including non-payment, breach of covenants, materially incorrect representations, cross-default, bankruptcy, and change of control. There are no cure periods for events of default due to non-payment of principal and breaches of negative and financial covenants, but non-payment of interest and breaches of certain affirmative covenants are subject to customary cure periods. As of ~~June 30, 2019,~~March 31, 2020, we were in compliance with all debt covenants.

On July 27, 2017, the U.K. Financial Conduct Authority announced that it intends to stop persuading or compelling banks to submit LIBOR rates after 2021. Our Credit Facility includes provisions to determine a replacement rate for LIBOR if necessary during its term, which require that we and our lenders agree upon a replacement rate based on the then-prevailing market convention for similar agreements. We currently do not expect the transition from LIBOR to have a material impact on us. However, if clear market standards and replacement methodologies have not developed as of the time LIBOR becomes unavailable, we may have difficulty reaching agreement on acceptable replacement rates under our Credit Facility. In the event that we do not reach agreement on an acceptable replacement rate for LIBOR, outstanding borrowings under the Credit Facility would revert to a floating rate equal to the alternative base rate (which, as of the time that LIBOR becomes unavailable, is equal to the greater of the Prime Rate and the Federal Funds effective rate plus 0.50%) plus the applicable margin for the alternative base rate which ranges between 0.75% to 1.75%. If we are unable to negotiate replacement rates on favorable terms, it could have a material adverse effect on our financial condition, results of operations, and cash distributions to unitholders.

Contractual Obligations

As of ~~June 30, 2019,~~March 31, 2020, there have been no material changes to our contractual obligations previously disclosed in our ~~2018~~2019 Annual Report on Form 10-K.

Off-Balance Sheet Arrangements

As of ~~June 30, 2019,~~March 31, 2020, we did not have any material off-balance sheet arrangements.

Critical Accounting Policies and Related Estimates

As of ~~June 30, 2019,~~March 31, 2020, there have been no significant changes to our critical accounting policies and related estimates previously disclosed in our ~~2018~~2019 Annual Report on Form 10-K.

New and Revised Financial Accounting Standards

The effects of new accounting pronouncements are discussed in the notes to our unaudited interim consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Commodity Price Risk

Our major market risk exposure is the pricing of oil, natural gas, and NGLs produced by our operators. Realized prices are primarily driven by the prevailing global prices for oil and prices for natural gas and NGLs in the United States. Prices for oil, natural gas, and NGLs have been historically volatile, and we expect this unpredictability to continue in the future. The prices that our operators receive for production depend on many factors outside of our or their control. To reduce the impact of fluctuations in oil and natural gas prices on our revenues, we use commodity derivative instruments to reduce our exposure to price volatility of oil and natural gas. The counterparties to the contracts are unrelated third parties. The contracts settle monthly in cash based on a designated floating price. The designated floating price is based on the NYMEX benchmark for oil and natural gas. We have not designated any of our contracts as fair value or cash flow hedges. Accordingly, the changes in fair value of the contracts are included in net income in the period of the change. See Note ~~5 –~~4 - Commodity Derivative Financial Instruments and Note ~~6 –~~5 - Fair Value Measurements to the unaudited interim consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q for additional information.

To estimate the effect lower prices would have on our reserves, we reduced the SEC commodity pricing for the ~~six~~three months ended ~~June 30, 2019~~March 31, 2020 by 10%. This results in an approximate 2%2.5% reduction of proved reserve volumes as compared to the unadjusted ~~June 30, 2019~~March 31, 2020 SEC pricing scenario.

Counterparty and Customer Credit Risk

Our derivative contracts expose us to credit risk in the event of nonperformance by counterparties. While we do not require our counterparties to our derivative contracts to post collateral, we do evaluate the credit standing of such counterparties as we deem appropriate. This evaluation includes reviewing a counterparty’s credit rating and latest financial information. As of ~~June 30, 2019,~~March 31, 2020, we had ~~nine~~8 counterparties, all of which were rated Baa1 or better by Moody’s and are lenders under our Credit Facility.

Our principal exposure to credit risk results from receivables generated by the production activities of our operators. The inability or failure of our significant operators to meet their obligations to us or their insolvency or liquidation may adversely affect our financial results. However, we believe the credit risk associated with our operators and customers is acceptable.

Interest Rate Risk

We have exposure to changes in interest rates on our indebtedness. As of ~~June 30, 2019,~~March 31, 2020, we had ~~$436.0~~$388.0 million of outstanding borrowings under our Credit Facility, bearing interest at a weighted-average interest rate of ~~4.66%~~3.22%. The impact of a 1% increase in the interest rate on this amount of debt would have resulted in an increase in interest expense, and a corresponding decrease in our results of operations, of ~~$2.2~~$1.0 million for the ~~six~~three months ended ~~June 30, 2019,~~March 31, 2020, assuming that our indebtedness remained constant throughout the period. We may use certain derivative instruments to hedge our exposure to variable interest rates in the future, but we do not currently have any interest rate hedges in place.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As required by Rule 13a-15(b) under the Securities Exchange Act of 1934 (the “Exchange Act”), we have evaluated, under the supervision and with the participation of management of our general partner, including our general partner’s principal executive officer and principal financial officer, 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) as of the end of the period covered by this Quarterly Report on Form 10-Q. Our disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed by us in reports that we file or submit under the Exchange Act is accumulated and communicated to management, including our general partner’s principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure and is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. Based upon that evaluation, our general partner’s principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of ~~June 30, 2019.~~March 31, 2020.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the quarter ended ~~June 30, 2019~~March 31, 2020 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings

Due to the nature of our business, we are, from time to time, involved in routine litigation or subject to disputes or claims related to our business activities. In the opinion of our management, none of the pending litigation, disputes or claims against us, if decided adversely, will have a material adverse effect on our financial condition, cash flows, or results of operations.

Item 1A. Risk Factors

In addition to the other information set forth in this report, readers should carefully consider the risks under the heading “Risk Factors” in our ~~2018~~2019 Annual Report on Form 10-K. Except to the extent updated below, there has been no material change in our risk factors from those described in our ~~2018~~2019 Annual Report on Form 10-K. These risks, as updated below, are not the only risks that we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may materially adversely affect our business, financial condition or results of operations.

~~Tax Risks to Common Unitholders~~

The tax treatment of publicly traded partnerships or an investment in our common units could be subject to potential legislative, judicial, or administrative changes and differing interpretations, possibly applied on a retroactive basis.

The present U.S. federal income tax treatment of publicly traded partnerships, including us, or an investment in our common units may be modified by administrative, legislative, or judicial changes or differing interpretations at any time. From time to time, members of Congress propose and consider similar substantive changes to the existing U.S. federal income tax laws that would affect publicly traded partnerships, including elimination of partnership tax treatment for publicly traded partnerships. For example, the “Clean Energy for America Act”, which is similar to legislation that was commonly proposed during the Obama Administration, was introduced in the Senate on May 2, 2019. If enacted, this proposal would, among other things, repeal Section 7704(d)(1)(E) of the Internal Revenue Code upon which we rely for our treatment as a partnership for U.S. federal income tax purposes. In addition, the Treasury Department has issued, and in the future may issue, regulations interpreting those laws that affect publicly traded partnerships. There can be no assurance that there will not be further changes to U.S. federal income tax laws or the Treasury Department's interpretation of the qualifying income rules in a manner that could impact our ability to qualify as a partnership in the future.

Any modification to the U.S. federal income tax laws may be applied retroactively and could make it more difficult or impossible for us to meet the exception for certain publicly traded partnerships to be treated as partnerships for U.S. federal income tax purposes. We are unable to predict whether any of these changes or other proposals will ultimately be enacted or adopted. Any such changes could negatively impact the value of an investment in our common units. You are urged to consult with your own tax advisor with respect to the status of regulatory or administrative developments and proposals and their potential effect on your investment in our common units.

Risks Related to our Business

~~If operators slow or cease activity~~The COVID-19 pandemic and the significant decline in commodity prices in the ~~Shelby Trough area,~~first quarter of 2020 has adversely affected our business, and the ultimate effect on our financial condition, results of operations, ~~could~~and cash distributions to unitholders will depend on future developments, which are highly uncertain and cannot be predicted.

The COVID-19 pandemic has adversely ~~affected.~~affected the global economy, disrupted global supply chains and created significant volatility in the financial markets. In addition, the pandemic has resulted in travel restrictions, business closures and the institution of quarantining and other restrictions on movement in many communities. As a result, there has been a significant reduction in demand for and prices of oil, natural gas and natural gas liquids ("NGLs"). This has been amplified due to the announcement by Saudi Arabia of a significant increase in its maximum oil production capacity as well as the announcement by Russia that previously agreed upon oil production cuts between members of the Organization of the Petroleum Exporting Countries and its broader partners (“OPEC+”) would expire on April 1, 2020, and the ensuing expiration thereof. On April 12, 2020, members of OPEC+ agreed to certain production cuts; however, these cuts are not expected to be enough to offset near-term demand loss attributable to the COVID-19 pandemic. In addition, concerns over the saturation of storage capacity for oil has further depressed prices.

~~In 2018,~~The impact of the COVID-19 pandemic and geopolitical events that increased the supply of low-priced oil have also negatively affected the oil and natural gas business environment, significantly reducing prices of oil, natural gas and NGLs. While we ~~generated 21.4%~~use derivative instruments to partially mitigate the impact of commodity price volatility, our revenues and ~~36.7%~~operating results depend significantly upon the prevailing prices for oil and natural gas. The current price environment has caused some of our operators’ wells to become uneconomic, which has resulted, or may result in the future, in suspension of production from ~~two~~those wells or a significant reduction in or no royalty revenues from existing production. Some operators may also attempt to shut in producing wells and avoid lease termination or payment of shut-in royalties by claiming force majeure, if provided for in the ~~Shelby Trough area~~applicable lease. Because these shut-ins have happened so recently, and no operator has, to our knowledge, claimed force majeure, we have not been able to quantify their impact on our future revenues.

The current price environment also caused us to determine that certain depletable units consisting of mature oil producing properties were impaired. Therefore, we recognized impairment of oil and natural gas properties of $51.0 million for three months ended March 31, 2020. Additionally, the borrowing base under the Credit Facility, which takes into consideration the estimated loan value of our oil and natural gas properties, was reduced from $650.0 million to $460.0 million, effective May 1, 2020. In a prolonged period of low commodity prices, we may be required to impair additional properties and the borrowing base under our credit facility could be further reduced. In light of the ~~Haynesville play in East Texas, where we own~~challenging business environment and uncertainty caused by the pandemic, the board of directors of our general partner (the "Board") also approved a ~~concentrated, relatively high-interest royalty position. These operators have recently decided to limit their Shelby Trough drilling activity, and one of the operators has released acreage~~reduction in the ~~area. Geographic~~quarterly distribution for the first quarter of 2020 to increase the amount of retained free cash flow for debt reduction and ~~operator concentration heightens~~balance sheet protection.

We enter into derivative instruments to partially mitigate the ~~effect~~impact of ~~operational risks, including:~~

~~operator's diversion of drilling capital to other areas, where~~commodity price volatility on our ~~royalty interest is less meaningful or nonexistent;~~

~~adverse changes to the operators' financial positions;~~

~~unanticipated geographic or environmental constraints in the Shelby Trough; or~~

~~delay or cancellation of construction or operation of LNG export facilities in the Gulf of Mexico.~~

~~If any of these risks are realized and production is not replaced by another operator in this area or another area, production may decrease, reducing~~ cash generated from operations. Any declines in production or production forecasts as a result of low commodity prices in light of COVID-19 pandemic and global oversupply could limit our ability to hedge future volumes.

The extent to which the COVID-19 pandemic adversely affects our business, results of operations, and ~~cash available for distribution.~~financial condition will depend on future developments, which are highly uncertain and cannot be predicted, including the scope and duration of the pandemic and actions taken by governmental authorities and other third parties in response to the pandemic.

²On November 5, 2018, the Board authorized the repurchase of up to $75.0 million in common units. The repurchase program authorizes us to make repurchases on a discretionary basis as determined by

management, subject to market conditions, applicable legal requirements, available liquidity, and other appropriate factors.

All or a portion of any repurchases may be made under a Rule 10b5-1 plan, which would permit common units to be

repurchased when we might otherwise be precluded from doing so under insider trading laws. The repurchase program does

not obligate us to acquire any particular amount of common units and may be modified or suspended at any time and could

be terminated prior to completion.
