NOTE 1—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 formed on September 16, 2014. On May 6, 2015, BSM completed its initial public offering (the “IPO”) of 22,500,000 common units representing limited partner interests at a price to the public of $19.00 per common unit. BSM received proceeds of $391.5 million from the sale of its common units, net of underwriting discount, structuring fee, and offering expenses (including costs previously incurred and capitalized). BSM used the net proceeds from the IPO to repay substantially all indebtedness outstanding under its ~~credit facility.~~Credit Facility, as defined in Note 7 – Credit Facility. On May 1, 2015, BSM’s common units began trading on the New York Stock Exchange under the symbol “BSM.”

Black Stone Minerals Company, L.P., a Delaware limited partnership, and its subsidiaries (collectively referred to as “BSMC” or the “Predecessor”) own oil and natural gas mineral interests in the United ~~States.~~States ("U.S."). In connection with the IPO, BSMC was merged into a wholly owned subsidiary of BSM, with BSMC as the surviving entity. Pursuant to the merger, the Class A and Class B common units representing limited partner interests of the Predecessor were converted into an aggregate of 72,574,715 common units and 95,057,312 subordinated units of BSM at a conversion ratio of 12.9465:1 for 0.4329 common units and 0.5671 subordinated units, and the preferred units of BSMC were converted into an aggregate of 117,963 Series A redeemable preferred units of BSM at a conversion ratio of one to one. The merger was accounted for as a combination of entities under common control with assets and liabilities transferred at their carrying amounts in a manner similar to a pooling of interests. Unless otherwise stated or the context otherwise indicates, all references to the “Partnership” or similar expressions for time periods prior to the IPO refer to Black Stone Minerals Company, L.P. and its subsidiaries, the Predecessor, for accounting purposes. For time periods subsequent to the IPO, these terms refer to Black Stone Minerals, L.P. and its subsidiaries.

In addition to mineral interests, which make up the vast majority of the asset base, the Partnership’s assets also include nonparticipating and overriding royalty interests. These interests, which are non-cost-bearing, are collectively referred to as “mineral and royalty interests.” As of September 30, ~~2017,~~2018, the Partnership’s mineral and royalty interests were located in 41 states and 64 onshore oil and natural gas producing basins of the continental ~~United States,~~U.S., including all of the major onshore producing basins. The Partnership also owns non-operated working interests in certain oil and natural gas properties.

New Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ~~("ASU"~~(“ASU”) 2014-09, Revenue from Contracts with Customers(Topic 606) that ~~will supersede~~supersedes Accounting Standards Codification ~~(“ASC”~~("ASC") 605, Revenue Recognition. Under the new standard, entities ~~will be~~are required to ~~use judgment and make estimates, including identifying performance obligations~~recognize revenues when promised goods or services are transferred to customers in ~~a contract, estimating~~an amount that reflects the ~~amount of variable~~ consideration to ~~include in the transaction price, allocating the transaction price to each separate performance obligation, and determining when~~which an entity ~~satisfies its performance obligations. The new standard also requires~~expects to be entitled for those goods or services, which may require more ~~detailed disclosures~~judgment than under previous U.S. GAAP. See Note 3 – Impact of ASC 606 Adoption for further details related to the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The new guidance is effective for fiscal years and interim periods beginning after December 15, 2017, with early adoption permitted. The standard allows for either “full retrospective” adoption, meaning that the standard is applied to all of the periods presented with a cumulative catch-up adjustment as of the earliest period presented, or “modified retrospective” adoption, meaning the standard is applied only to the most current period presented in the financial statements with a cumulative catch-up as of the current period.

~~The Partnership intends to use the modified retrospective adoption approach and~~ ~~does not plan to early adopt~~. The Partnership has completed its review of a representative sample of revenue contracts covering its material revenue streams that was designed to evaluate any potential changes in revenue recognition uponPartnership’s adoption of the new standard, and based on evaluations to-date, the implementation of the new standard is not anticipated to have a material impact on the consolidated financial statements. The Partnership is concurrently evaluating the information technology and internal control changes that will be required to implement the new standard based on the results of its contract review process. The Partnership continues to evaluate the disclosure requirements of this ~~new guidance, and expects to fully complete its evaluation of the impacts of ASU 2014-09 to the consolidated financial statements and related disclosures by 2017 year end~~standard..

BLACK STONE MINERALS, L.P. AND SUBSIDIARIES

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

In February 2016, the FASB issued ASU 2016-02,Leases(Topic 842), which ~~requires~~will supersede the lease requirements in Topic 840, Leases by requiring lessees to recognize ~~the~~ lease assets and lease liabilities classified as operating leases on the balance sheet. The new lease standard will be effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, and early adoption is permitted.

The FASB recently issued ASU 2018-11, Leases (Topic 842), Targeted Improvements, which would allow entities to apply the transition provisions of the new standard at the adoption date instead of at the earliest comparative period presented in the consolidated financial statements, and will also allow entities to continue to apply the legacy guidance in Topic 840, including disclosure requirements, in the comparative period presented in the year the new leases standard is adopted. Entities that elect this option would still adopt the new leases standard using a modified retrospective transition method, but would recognize a cumulative catch-up adjustment in the period of adoption rather than in the earliest period presented. The Partnership ~~will~~plans to use ~~the~~a modified retrospective transition method to apply the new standard to leases that exist as of the adoption ~~approach and~~date of January 1, 2019. The Partnership does not plan to early adopt.

Based on ~~current~~ evaluations to-date, the ~~Partnership does not anticipate this~~ new guidance will not have a material impact on ~~its~~the Partnership's consolidated financial statements and related disclosures as this guidance does not apply to leases to explore for or use minerals, oil, natural gas, and similar resources.

In August ~~2016,~~2018, the FASB issued ASU ~~2016-15,~~2018-13, ~~Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments~~ ~~(Topic 230)~~Fair Value Measurement (Topic 820), ~~to address diversity in practice of how~~which will remove, modify, and add certain ~~cash receipts and cash payments are currently presented and classified in~~required disclosures on fair value measurements. As amended, Topic 820 will no longer require the ~~statement of cash flows. The ASU addresses the topic of separately identifiable cash flows and application~~disclosure of the ~~predominance principle. Classification~~amount of ~~cash receipts~~ and ~~payments that have aspects~~reasons for transfers between Level 1 and Level 2 of ~~more than one class~~the fair value hierarchy, the policy of ~~cash flows should be determined first by applying specific guidance, and then by the nature~~timing of ~~each separately identifiable cash flow. In situations where there is an absence of specific guidance~~transfers between levels, and the ~~cash flow has aspects~~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 ~~than one type~~reasonable and rational method to reflect the distribution of ~~classification, the predominance principle should be applied whereby the cash flow classification should depend on~~

~~NOTES TO CONSOLIDATED FINANCIAL STATEMENTS~~

~~the activity that is likely~~unobservable inputs used to ~~be the predominant source or use of cash flows.~~develop Level 3 fair value measurements. The new ~~guidance is~~standard will be effective ~~for public business entities~~ for fiscal years beginning after December 15, ~~2017,~~2019, including interim periods within those fiscal years, and early adoption is permitted. The Partnership intends to use the retrospective transition method, 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.

~~In January 2017, the FASB issued ASU 2017-01,~~ ~~Business Combinations~~ (Topic 805), which clarifies the definition of a business in order to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The FASB issued this ASU in response to stakeholder feedback that the current definition of a business in ASC 805 is being applied too broadly and the application of the guidance was not resulting in consistent application in a cost-effective manner. This ASU provides a screen whereby a transaction will be accounted for as an asset purchase (or disposal) if substantially all of the fair value of the gross assets acquired (disposed) is concentrated in a single identifiable asset or a group of similar identifiable assets. If the screen is not met, the entity will evaluate whether it is a business acquisition under revised criteria. The ASU is effective for public business entities for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted under certain circumstances. The amendments in this ASU should be applied prospectively as of the beginning of the period of adoption. 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.

~~In May 2017, the FASB issued ASU 2017-09~~ ~~Compensation-Stock Compensation: Scope of Modification Accounting~~ ~~(Topic 718)~~. The update provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting under Topic 718. The amendments require an entity to account for the effects of a modification unless all of the following conditions are met:

~~The fair value (or intrinsic or calculated value if elected) of the modified award is the same as the value of the original award immediately before the original award was modified.~~

~~The vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified.~~

~~The classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified.~~

This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted. The amendments in this ASU should be applied prospectively to an award modified on or after the adoption date. 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—ASSET RETIREMENT OBLIGATIONS~~3 — IMPACT OF ASC 606 ADOPTION

ASC 606, Revenue from Contracts with Customers, requires the Partnership to identify the distinct promised goods and services within a contract which represent separate performance obligations and determine the transaction price to allocate to the performance obligations identified. The ~~asset retirement obligations (“ARO”) liability reflects~~Partnership adopted ASC 606 using the ~~present value~~modified retrospective method, which was applied to all existing contracts for which all (or substantially all) of ~~estimated costs~~the revenue had not been recognized under legacy revenue guidance as of ~~dismantlement, removal, site reclamation,~~the date of adoption, January 1, 2018.

Revenues from Contracts with Customers

Oil and ~~similar activities associated with the Partnership’s working-interest~~natural gas sales

Sales of oil and natural gas ~~properties. The Partnership utilizes current retirement costs to estimate~~are recognized at the expected cash outflows for retirement obligations. The Partnership estimates the ultimate productive life of its properties, a credit-adjusted risk-free rate, and an inflation factor in order to determine the current present value of these obligations. To the extent future revisions to these assumptions impact the present valuepoint control of the ~~existing ARO liability,~~product is transferred to the customer and collectability of the sales price is reasonably assured. Oil is priced on the delivery date based upon prevailing prices published by purchasers with certain adjustments related to oil quality and physical location. The price the Partnership receives for natural gas is tied to a ~~corresponding adjustment~~market index, with certain adjustments based on, among other factors, whether a well delivers to a gathering or transmission line, quality and heat content of natural gas, and prevailing supply and demand conditions, so that the price of natural gas fluctuates to remain competitive with other available natural gas supplies. As each unit of product represents a separate performance obligation and the consideration is ~~made~~variable as it relates to ~~the~~ oil and natural gas ~~property balance. The following table describes changes to~~prices, we recognize revenue from oil and natural gas sales using the ~~Partnership’s ARO liability during the period:~~practical expedient for variable consideration in ASC 606.

Lease bonus and other income

BLACK STONE MINERALS, L.P. AND SUBSIDIARIES

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

The Partnership also earns revenue from lease bonuses and delay rentals. The Partnership generates lease bonus revenue by leasing its mineral interests to exploration and production companies. A lease agreement represents the Partnership's contract with a customer and generally transfers the rights to any oil or natural gas discovered, grants the Partnership a right to a specified royalty interest, and requires that drilling and completion operations commence within a specified time period. Control is transferred to the lessee and the Partnership has satisfied its performance obligation when the lease agreement is executed, such that revenue is recognized when the lease bonus payment is received. At the time the Partnership executes the lease agreement, the Partnership expects to receive the lease bonus payment within a reasonable time, though in no case more than one year, such that the Partnership has not adjusted the expected amount of consideration for the effects of any significant financing component per the practical expedient in ASC 606. The Partnership also recognizes revenue from delay rentals to the extent drilling has not started within the specified period, payment has been received, and the Partnership has no further obligation to refund the payment.

Production imbalances

The Partnership previously elected to utilize the entitlements method to account for natural gas production imbalances, which is no longer permitted under ASC 606. As of January 1, 2018, these amounts were de minimis. As such, upon adoption of ASC 606, there was no material impact to the financial statements due to this change in accounting for the Partnership's production imbalances.

Allocation of transaction price to remaining performance obligations

Oil and natural gas sales

The Partnership has utilized the practical expedient in ASC 606 which states the Partnership is not required to disclose the transaction price allocated to remaining performance obligations if the variable consideration is allocated entirely to a wholly unsatisfied performance obligation. As the Partnership has determined that each unit of product generally represents a separate performance obligation, future volumes are wholly unsatisfied and disclosure of the transaction price allocated to remaining performance obligations is not required.

Lease bonus and other income

Given that the Partnership does not recognize lease bonus or other income until a lease agreement has been executed, at which point its performance obligation has been satisfied, and payment is received, the Partnership does not record revenue for unsatisfied or partially unsatisfied performance obligations as of the end of the reporting period. Overall, there were no material changes in the timing of the satisfaction of the Partnership's performance obligations or the allocation of the transaction price to its performance obligations in applying the guidance in ASC 606 as compared to legacy U.S. GAAP.

Prior-period performance obligations

The Partnership records revenue in the month production is delivered to the purchaser. As a non-operator, the Partnership has limited visibility into the timing of when new wells start producing and production statements may not be received for 30 to 90 days or more after the date production is delivered. As a result, the Partnership is required to estimate the amount of production delivered to the purchaser and the price that will be received for the sale of the product. The expected sales volumes and prices for these properties are estimated and recorded within the Accounts receivable line item in the accompanying consolidated balance sheets. The difference between the Partnership's estimates and the actual amounts received for oil and natural gas sales is recorded in the month that payment is received from the third party. For the three and nine months ended September 30, 2018, revenue recognized in the reporting periods related to performance obligations satisfied in prior reporting periods was immaterial.

Noble Acquisition

On November 28, 2017 (the "Close Date"), BSMC closed on the acquisition of (i) certain mineral interests and other non-cost bearing royalty interests from Noble Energy Inc., Noble Energy Wyco, LLC, and Rosetta Resources Operating LP and (ii) one hundred percent (100%) of the issued and outstanding securities of Samedan Royalty, LLC ("Samedan") from Noble Energy US Holdings, LLC, collectively, the "Noble Acquisition."

The mineral interests and other non-cost bearing royalty interests acquired in the Noble Acquisition, including interests owned by Samedan (the "Noble Assets") include approximately 1.1 million gross (140,000 net) mineral acres, 380,000 gross acres of non-participating royalty interests, and 600,000 gross acres of overriding royalty interests collectively spread over 20 states with significant concentrations in Texas, Oklahoma, and North Dakota.

The Partnership funded the $335.0 million purchase price (before customary post-closing adjustments) using (i) approximately $300.0 million in proceeds from its issuance of 14,711,219 Series B cumulative convertible preferred units to Mineral Royalties One, L.L.C., an affiliate of The Carlyle Group (the "Purchaser"), in a private placement which also closed on November 28, 2017, and (ii) approximately $35.0 million from borrowings under its Credit Facility. See additional discussion of the Series B cumulative convertible preferred units in Note 10 – Preferred Units.

BLACK STONE MINERALS, L.P. AND SUBSIDIARIES

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

The transaction was accounted for as a business combination using the acquisition method of accounting which requires, among other things, that the assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date. The final determination of fair value remains preliminary and will be completed after post-closing purchase price adjustments are finalized, but in no case later than one year from the acquisition date. Since December 31, 2017, the Partnership has recorded an adjustment to the purchase price to reduce the amount allocated to unproved properties by $3.2 million, which reduces the Acquisitions of oil and natural gas properties line item of the consolidated statement of cash flows for the nine months ended September 30, 2018.

The following table summarizes the adjusted allocation of the fair value of the assets acquired and the acquisition-related costs as of September 30, 2018:

²	Acquisition-related costs were expensed and included in the General and administrative expense line item of the consolidated statement of operations for the year ended December 31, 2017.

The fair value of the Noble Assets was measured using valuation techniques that convert future cash flows to a single discounted amount. Significant inputs to the valuation of oil and natural gas properties include estimates of: (i) oil and natural gas reserves; (ii) future commodity prices; (iii) estimated future cash flows; and (iv) market-based weighted average cost of capital. These inputs require significant judgments and estimates by the Partnership's management at the time of the valuation and are the most sensitive and subject to change.

Actual and Pro Forma Impact of Noble Acquisition (Unaudited)

The ~~cash portion~~historical financial information was adjusted to give effect to the pro forma events that were directly attributable to the Noble Acquisition and are factually supportable. The unaudited pro forma consolidated results are not necessarily indicative of ~~all acquisitions during~~what the Partnership's consolidated results of operations would have been had the acquisition been completed on January 1, 2017. In addition, the unaudited pro forma consolidated results do not purport to project the future results of operations for the combined company.

The unaudited pro forma consolidated results reflect the following pro forma adjustments for the periods presented:

Adjustments to recognize incremental revenue, production costs and ad valorem taxes, and depreciation, depletion, and amortization expense attributable to the Noble Assets.

Adjustment to recognize additional interest expense associated with the incremental borrowings under the Partnership's Credit Facility.

Adjustment to recognize the quarterly distribution associated with the issuance of 14,711,219 Series B cumulative convertible preferred units.

The Series B cumulative convertible preferred units were not included in the calculation of pro forma diluted earnings per common unit for the three months ended September 30, 2017 as they were anti-dilutive under the if-converted method.

The Series B cumulative convertible preferred units were included in the calculation of pro forma diluted earnings per common unit for the nine months ended September 30, 2017 due to their dilutive effect under the if-converted method.

The Series B cumulative convertible preferred units do not have any impact to earnings per subordinated unit.

Farmout Agreements

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~~ Haynesville/Bossier ~~shale~~ acreage in San Augustine County, Texas operated by XTO Energy Inc. The Partnership has an approximate 50% working interest in the acreage and is the largest mineral owner. ~~A total of 18 wells are anticipated to be drilled over an initial phase, beginning with wells spud after January 1, 2017.~~ At its option, ~~Canaan may participate in two additional phases with each phase continuing for the lesser of two years or until an additional 20 wells have been drilled. During~~during the first three phases of the agreement, Canaan ~~will~~can commit on a phase-by-phase basis ~~and~~to fund ~~80%~~a portion of the Partnership's drilling and completion costs ~~and will be assigned 80%~~to earn a percentage of the Partnership's working ~~interests~~interest in ~~such~~ wells ~~(40% working interest on an 8/8ths basis).~~drilled and completed during each phase. After the third phase, Canaan can earn ~~40%~~a percentage of the ~~Partnership’s~~Partnership's working interest ~~(20% working interest on an 8/8ths basis)~~ in additional wells drilled in the area by ~~continuing~~committing on a well-by-well basis to fund ~~40%~~a portion of the Partnership's costs for ~~those wells on a well-by-well basis.~~each well. The Partnership will receive an overriding royalty interest (“ORRI”) before payout and an increased ORRI after payout on all wells drilled under the agreement. ~~The execution~~

Since the inception of ~~this~~the agreement, ~~is anticipated~~the Partnership has received $62.2 million from Canaan under the agreement. All amounts received are included in the Other long-term liabilities line item of the September 30, 2018 consolidated balance sheet, as no working interest had been assigned to ~~offset~~Canaan as of that date. Subsequent to September 30, 2018, the Partnership assigned to Canaan working interests in wells drilled and completed during the initial phase, reducing the Other long-term liabilities balance associated with the Canaan farmout agreement.

Pivotal Farmout

On November 21, 2017, the Partnership entered into a farmout agreement with a portfolio company of Tailwater Capital, LLC, Pivotal Petroleum Partners (“Pivotal”), that covers substantially all of the Partnership's ~~future capital expenditures~~remaining working interests under active development in the Shelby Trough area of East Texas targeting its Haynesville/Bossier acreage after giving effect to the Canaan Farmout (discussed above) over the next eight years. In wells operated by ~~approximately $30~~XTO Energy Inc. in San Augustine County, Texas, Pivotal will earn the Partnership's remaining working interest not covered by the Canaan Farmout, as well as the Partnership's working interests in wells operated by its other major operator in the area. After the funding of a designated group of wells by Pivotal and once Pivotal achieves a specified payout for such well group, the Partnership will obtain a majority of the original working interest in the designated group of wells.

Since the inception of the agreement, the Partnership has received $35.5 million from Pivotal under the agreement. As of September 30, 2018, the Partnership had assigned to ~~$35 million~~Pivotal working interests in ~~2017~~wells drilled and ~~by an average of $40 to $50 million annually~~completed during the ~~term~~initial phase, and as such, only $27.5 million is included in the Other long-term liabilities line item of the ~~agreement.~~consolidated balance sheet.

NOTE ~~5—DERIVATIVES AND~~5 — 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 derivative instruments. From time to time, such instruments may include ~~fixed-price-swap contracts,~~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.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

As of September 30, ~~2017,~~2018, the Partnership’s open derivative contracts consisted of ~~only fixed-price-swap~~fixed-price swap contracts and costless collar contracts. A ~~fixed-price-swap~~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, any 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”~~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 September 30, ~~2017~~2018 and December 31, ~~2016.~~2017. See Note 6 – Fair Value ~~Measurement~~Measurements for further discussion.

The Partnership's derivative contracts expose it to credit risk in the event of nonperformance by counterparties. 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 September 30, ~~2017,~~2018, the Partnership had ~~nine~~ten counterparties, all of which are rated Baa1 or better by Moody’s. ~~Seven~~Nine of the Partnership's counterparties are lenders under the ~~Partnership's credit facility.~~Credit Facility.

NOTE 6—6 — FAIR VALUE ~~MEASUREMENT~~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 nine months ended September 30, ~~2017~~2018 or the year ended December 31, ~~2016.~~2017.

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 September 30, ~~2017~~2018 and December 31, ~~2016~~2017 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.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Nonfinancial assets and liabilities measured at fair value on a nonrecurring 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, 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 – ~~Acquisitions~~Oil and ~~Dispositions.~~Natural Gas Properties Acquisitions.

Oil and natural gas properties are measured at fair value on a nonrecurring 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 ~~economic~~proved reserves, future ~~operating and development costs,~~commodity prices, timing of future ~~commodity prices,~~production, future capital expenditures, and a risk-adjusted discount rate.

The Partnership’s estimates of fair value have been determined at discrete points in time based on relevant market data. These estimates involve uncertainty and cannot be determined with precision. There were no significant changes in valuation techniques or related inputs as of September 30, ~~2017~~2018 or December 31, ~~2016.~~2017.

~~The following table presents information about the Partnership’s~~There were no assets measured at fair value on a nonrecurring ~~basis:~~basis, after initial recognition, for the three and nine months ended September 30, 2018 and 2017.

NOTE 7—7 — CREDIT FACILITY

The Partnership maintains a senior secured revolving credit agreement, as amended (the ~~“Senior Line of Credit”~~“Credit Facility”). The ~~Senior Line of~~ Credit Facility has a maximum credit amount of $1.0 billion. The amount of the borrowing base 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. ~~Drawings on the Senior Line of Credit are used for the acquisition of oil and natural gas properties and for other general business purposes.~~

~~Effective April 15, 2016, the~~The borrowing base ~~was $450.0 million. The Partnership's fall 2016 borrowing base redetermination process resulted~~is redetermined semi-annually, usually in ~~an increase in the borrowing base to $500.0 million, which became effective~~ October ~~31, 2016.~~ and April.

Effective April 25, 2017, the borrowing base redetermination ~~resulted in an increase~~increased the borrowing base from $500.0 million to $550.0 million.

On November 1, 2017, the Partnership amended and restated the credit agreement to ~~extend the maturity thereof for a term of five years,~~ create a swingline facility ~~and~~that permits short-term borrowings on same-day notice, make other changes to the hedging and restrictive ~~covenants. There was no change to~~covenants, and extend the ~~borrowing base. The Senior Line~~maturity for a term of ~~Credit now~~five years, which terminates on November 1, 2022.

Prior to October 31, 2016, borrowings under the Senior Line of Credit bore interest at LIBOR plus a margin between 1.50% and 2.50%, or the Prime Rate plus a margin between 0.50% and 1.50%, with the margin depending on Effective May 4, 2018, the borrowing base ~~utilization percentage. The Prime Rate~~ was ~~determined~~increased to ~~be the higher of the financial institution’s prime rate or the federal funds~~$600.0 million and, effective ~~rate plus 0.50% per annum.~~

Effective October 31, 2018, the LIBOR margin was reduced to between 1.75% and 2.75% and the Prime Rate margin was reduced to between 0.75% and 1.75%.

The weighted-average interest rate of the ~~Senior Line of~~ Credit Facility was ~~3.74%~~4.75% and ~~3.26%~~4.06% as of September 30, ~~2017~~2018 and December 31, ~~2016,~~2017, 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% per annum if the borrowing base utilization percentage is equal to or greater than 50%. The ~~Senior Line of~~ Credit Facility is secured by substantially all of the Partnership’s producing ~~oil and natural gas assets.~~properties.

The ~~Senior Line of~~ Credit Facility contains various limitations on future borrowings, leases, hedging, and sales of assets. Additionally, the ~~Senior Line of~~ 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.

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 to the Purchaser for a cash purchase price of $20.3926 per Series B cumulative convertible preferred unit, resulting in total proceeds of approximately $300 million.

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, 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.

The Series B cumulative convertible preferred units had a carrying value of $298.4 million and $295.4 million, including accrued distributions of $5.3 million and $1.9 million, as of September 30, 2018 and December 31, 2017, respectively. 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—~~11 — 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 and subordinated units have all the rights of a unitholder, including non-forfeitable distribution rights. As participating securities, the restricted common and subordinated 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 ~~redeemable~~Series B cumulative convertible preferred units could be converted into ~~0.8~~approximately 15.0 million common ~~units and 1.0 million subordinated~~ units as of September 30, ~~2017.~~ 2018.

At September 30, ~~2017,~~2018, if the outstanding ~~redeemable~~Series B cumulative convertible preferred units were converted to common ~~and subordinated~~ units, the effect would be ~~anti-dilutive.~~ anti-dilutive; therefore, they are not included in the calculation of diluted EPU for the three and nine months ended September 30, 2018.

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. At September 30, ~~2017,~~2018, there were no units related to the Partnership’s restricted performance unit awards included in the calculation of diluted EPU.

NOTE ~~12—~~12 — 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 ~~price~~amount of up to $100,000,000. Sales of common units, if any, 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.~~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 ~~Securities and Exchange Commission~~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.

~~Through~~For the nine months ended September 30, ~~2017,~~2018, the Partnership sold ~~1.9 million~~2,121,643 common units under the ATM Program for net proceeds of ~~$31.3~~$38.4 million.

Overview

We are one of the largest owners 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 the marketing of our mineral assets for lease, creative structuring of terms on those leases to encourage and accelerate drilling activity, and selectively participating alongside our lessees on a working-interest basis in ~~low-risk development-drilling~~low–risk development–drilling opportunities on our interests. Our primary business objective is to grow our reserves, production, and cash generated from operations over the long term, while paying, to the extent practicable, a ~~growing~~ quarterly distribution to our unitholders.

As of September 30, ~~2017,~~2018, our mineral and royalty interests were located in 41 states and 64 onshore basins in the continental United States. These non-cost-bearing interests include ownership in ~~approximately 53,000~~over 55,000 producing wells. We also own non-operated working interests, ~~largely~~a significant portion of which are on our positions where we also have a mineral and royalty ~~interests.~~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 ~~production from~~produced is transferred to the ~~associated acreage~~customer and collectability of the sales price is ~~sold.~~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

~~During~~In the first nine months of ~~2017, we closed numerous acquisitions consisting of various mineral and royalty interests in several Texas counties. In the first quarter of 2017,~~2018, we acquired mineral and royalty interests primarily in the Permian Basin and in East Texas ~~prospective~~ for ~~the Haynesville and Bossier shales for a total~~aggregate consideration of ~~$17.6~~$109.6 million in cash and ~~$0.2~~$22.5 million in our common ~~units, as well as mineral and royalty interests in the Delaware Basin for $30.8 million in cash and $12.0 million in common~~ units. In the second quarter of 2017, we acquired additional mineral and royalty interests in East Texas for $18.1 million in cash and $45.7 million in our common units, primarily through the acquisition of the Angelina County Lumber Company. In the third quarter of 2017, we acquired additional mineral and royalty interests in East Texas for $22.2 million in cash and $13.7 million in our common units, as well as mineral and royalty interests in the Anadarko Basin for $0.4 million in cash. Additional information regarding acquisitions is contained in Note 4 -– Oil and Natural Gas Properties Acquisitions ~~and Dispositions to our unaudited consolidated financial statements included herein for further discussion.~~

~~At-the-Market Offering Program~~

In the second quarter of 2017, we commenced an at-the-market offering program (the “ATM Program”) and in connection therewith entered into an Equity Distribution Agreement. The ATM Program permits us from time to time through our Sales Agents to sell our common units having an aggregate offering price of up to $100,000,000. We intend to use the net proceeds from any sales pursuant to the ATM Program, after deducting commissions and offering expenses, for general partnership purposes, which may include, among other things, repayment of indebtedness outstanding under our credit facility. Common units to be sold pursuant to the Equity Distribution Agreement will be offered and sold pursuant to our existing effective shelf-registration statement on Form S-3 (File No. 333-215857), which was declared effective by the Securities and Exchange Commission on February 8, 2017. Proceeds, net of commissions and expenses, of these sales through September 30, 2017 amounted to $31.3 million. See Note 12 - At-the-Market Offering Program to our unaudited consolidated financial statements included herein for further discussion.

~~Farmout Agreement~~PepperJack Prospect

We have cumulatively spent approximately $13.1 million to drill two wells within our PepperJack prospect in Hardin and Liberty counties, Texas. The PepperJack A#1 well targeting the Lower Wilcox formation was drilled during the fourth quarter of 2017 and the first quarter of 2018. The PepperJack B#1 well, also targeting the Lower Wilcox formation, was drilled during the second quarter of 2018 to further delineate the prospect.

Based on the log results, we believe the PepperJack A#1 well is highly prospective and will be completed as a commercially productive well. The PepperJack B#1 well, which was a significant step-out from the PepperJack A#1 well, is not likely to be completed in the near term. Accordingly, we have recorded $6.8 million of capitalized costs for the PepperJack B#1 well to the Exploration expense line item of the consolidated statements of operations for the nine months ended September 30, 2018.

On ~~February~~September 21, ~~2017, we announced that~~2018, we entered into ~~a farmout~~an exploration agreement with ~~Canaan Resource Partners ("Canaan",~~a consortium of private exploration and ~~such farmout,~~production companies (the “Development Partners”) to further delineate and develop the ~~"Canaan Farmout"), which covers certain Haynesville and Bossier shale acreage in San Augustine County, Texas operated by XTO Energy Inc. We have an approximate 50%~~PepperJack prospect. As part of the agreement, we assigned 75% of our working interest in the ~~acreage. A total~~PepperJack A#1 well and acreage in the associated unit to the Development Partners and transferred our status as the operator of ~~18 wells are anticipated to be drilled over an initial phase, beginning with wells spud after January 1, 2017. At its option, Canaan may participate in two additional phases with each phase continuing~~record. We received proceeds of $6.4 million for the ~~lesser of two years or until 20 wells have been drilled. During the first three phases~~assignment, which represented a reimbursement for 100% of the ~~agreement, Canaan will commit on a phase-by-phase basis and fund 80% of our~~ drilling ~~and completion~~ costs and ~~will be assigned 80%~~associated acreage, proceeds of $1.0 million for an option covering our working interests in such wells (40% working interest on an 8/8ths basis). After the third phase, Canaan can earn 40% of our working interest (20% working interest on an 8/8ths basis) in additional wells drilledminerals and leases in the PepperJack prospect area, ~~by continuing to fund 40% of our costs for those wells on a well-by-well basis. We will receive a base~~and an overriding royalty interest ~~(“ORRI”) before payout~~in the PepperJack prospect area. The Development Partners will begin completion operations on the PepperJack A#1 well in the fourth quarter of 2018 and an additional ORRI after payout on all wells drilled under the agreement. The execution of this agreement is anticipated to offset our future capital expenditures by approximately $40 to $50 million annually during the term of the agreement.

we will participate as a 25% non-operated working interest owner.

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.

Commodity Prices

Oil and natural gas prices have been historically volatile based upon the dynamics of supply and demand. The U.S. ~~crude oil and petroleum product markets were significantly disrupted by Hurricane Harvey's landfall in Texas and Louisiana at the end of August. At the peak of disruption, the~~ Energy Information ~~Agency~~Administration ("EIA") estimates that 3.9 million barrels per day of U.S. Gulf Coast refining capacity was taken offline. Oil transportation capacity in the region was also restricted after the hurricane. According to the EIA, producers also curtailed production in the Eagle Ford region of South Texas; however production declines in that area were offset by growth in other areas of the lower 48 states onshore region. In early to mid-September, the petroleum supply system on the Gulf Coast began to return to service. The EIA reported that lower refinery demand for crude oil in the Gulf Coast region more than offset reductions in crude oil production as a result of the storm, which contributed to lower West Texas Intermediate ("WTI") prices and simultaneously contributed to higher product prices.

Higher crude oil prices in September reflected declining global inventories, thus increasing expectations for global economic and oil demand growth; falling production from the Organization of the Petroleum Exporting countries contributed to global oil inventory withdrawals in 2017. The EIA believes the appearance of strengthening economic conditions could contribute to oil demand growth in 2018. The EIA forecasts that the WTI spot oil price will average ~~$50.50~~$68.00 per ~~barrel~~Bbl in ~~2018.~~

~~As rising~~2018 and $69.00 per Bbl in 2019 and that the Henry Hub spot natural gas production is keeping pace with increasing consumption and demand for exports, particularly for liquefied natural gas ("LNG"), the EIA projects a balanced market from the last quarter of 2017 through 2018. The EIA expects LNG export capacity to increase, with LNG exports projected to exceed 3 Bcf per day in 2018. In addition, increased takeaway capacity out of the Marcellus/Utica shale plays, as a result of several new pipeline projects, is anticipated to increase overall production. The EIA estimates that Henry Hub natural gas spot prices will ~~rise from an annual~~ average ~~of $3.03~~$2.99 per ~~MMbtu~~MMBtu in ~~2017 to $3.19~~2018 and $3.12 per ~~MMbtu~~MMBtu in ~~2018.~~2019.

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 exclusively~~consisting of fixed-price swap contracts and costless collar contracts.

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

Rig Count

As we are not the operator of record on ~~only three~~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. According to the EIA, ~~injections of~~growing U.S. natural gas ~~into underground storage exceeded market expectations~~production is expected to support both increasing domestic consumption and ~~historical averages for~~higher natural gas exports. The EIA forecasts that natural gas inventories will reach almost 1.4 trillion cubic feet on March 31, 2019, which would be 17% lower than the ~~first three weeks of September 2017.~~

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 ~~distributable cash flow,~~ and distributable cash ~~flow after net working interest capital expenditures.~~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 comprise 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”) 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 NYMEX prices are referred to as differentials. All of 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 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 ~~crude~~ 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 ~~crude~~ 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 ~~use~~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 ~~swaps,~~contracts, costless collars, and other contractual arrangements. The impact of these derivative instruments could affect the amount of revenue we ultimately realize. ~~Since 2015, we have only entered into~~

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 the fixed ceiling price from the counterparty and we pay the market price. If the market price is below the fixed floor price, we receive the fixed floor price and we pay the market price. If the market price is between the fixed floor and fixed ceiling price, no payments are due from either party.

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 September 30, ~~2017, and as of the date of this filing,~~2018 are detailed in Note 5 – ~~Derivatives and~~Commodity Derivative Financial Instruments to our unaudited consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q. ~~Our~~

Prior to amending and restating our credit agreement ~~limits the extent to which we can hedge our future production.~~

~~As of September 30,~~on November 1, 2017, ~~per the terms of our credit agreement,~~ we were allowed to hedge all of our estimated production from our proved developed producing reserves based on the most recent reserve information provided to our lenders. Under these terms, we hedged approximately 92.5% and 98.7% of our available oil and condensate hedge volumes, respectively, and almost 92.4% and 99% of our available natural gas hedge volumes for the remainder of 2017 and 2018, respectively.

Pursuant to ~~the closing of~~ our Fourth Amended and Restated ~~credit agreement on November 1, 2017,~~Credit Agreement, we are allowed to hedge ~~expected production volumes in excess of estimated production from our proved developed reserves. The revised provisions in our credit agreement allow us to hedge~~ certain percentages of expected future monthly production volumes equal to the lesser of (i) internally forecasted production orand (ii) the average of reported production for the most recent three months.

We are allowed to hedge up to 90% of ~~production~~such volumes for the first 24 months, 70% for months 25 through 36, and 50% for months 37 through 48. Pursuant to our updated hedge provisions, we have hedged ~~approximately 95%~~79%, ~~99%~~70%, and 23% of our available oil and condensate hedge volumes for ~~the remainder of 2017,~~ 2018, 2019, and ~~2019,~~2020, respectively. Also, we have hedged ~~99%, 99%,~~83% and ~~28%~~56% of our available natural gas hedge volumes for ~~the remainder of 2017,~~ 2018 and 2019, respectively.

~~The Company intends~~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 ~~remain significantly hedged~~such production for the following 12 to 2430 months. We do not enter into derivative instruments for speculative purposes.

Non-GAAP Financial Measures

Adjusted EBITDA ~~distributable cash flow,~~ and distributable cash flow ~~after net working interest capital expenditures~~ 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, cash interest expense, and distributions to noncontrolling interests and preferred unitholders. ~~We define distributable cash flow after net working interest capital expenditures as distributable cash flow less net working interest capital~~

expenditures. Net working interest capital expenditures consist of all capital expenditures related to working interest wells less the recoupment of working interest expenditures under our farmout agreement.

Adjusted EBITDA ~~distributable cash flow,~~ and distributable cash flow ~~after net working interest capital expenditures~~ 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 generally accepted accounting principles in the United States (“U.S. GAAP”) as measures of our financial performance.

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

The following table presents a reconciliation of ~~Adjusted EBITDA, distributable cash flow and distributable cash flow after net working interest capital expenditures to~~ net income, ~~(loss),~~ the most directly comparable U.S. GAAP financial measure, to Adjusted EBITDA and distributable cash flow for the periods indicated:

As a ~~mineral-and-royalty-interest~~mineral and royalty interest owner, we are often provided insufficient and inconsistent data on NGL volumes by our operators. As a result, we are unable to reliably determine the total volumes of NGLs associated with the production of natural gas on our acreage. Accordingly, no NGL volumes are included in our reported production; however, revenue attributable to NGLs is included in our natural gas revenue and our calculation of realized prices for natural gas.

Revenue

Total revenue for the quarter ended September 30, ~~2017 decreased~~2018 increased compared to the quarter ended September 30, ~~2016. Production for the quarter ended September 30, 2017 averaged 37.0 MBoe per day, an~~2017. The increase ~~of 2.0 MBoe per day compared to~~in total revenue from the corresponding prior period ~~in 2016. The decrease in total revenue~~ is primarily due to ~~losses on commodity derivative instruments, partially offset by higher~~increased oil and condensate sales and natural gas and NGL sales as a result of increased production volumes and ~~lease bonus~~higher realized commodity prices. The overall increase in total revenue ~~as compared to~~was partially offset by the ~~corresponding period in 2016.~~increased loss on commodity derivative instruments.

Oil and condensate sales. Oil and condensate sales during the ~~period~~current quarter were ~~modestly lower~~higher than the third quarter of ~~2016~~2017 primarily due to ~~lower~~increased production volumes ~~from our Bakken assets.~~and higher realized commodity prices. Our ~~mineral-and-royalty-interest~~mineral and royalty interest oil and condensate volumes ~~decreased5.3%~~increased 58% in the third quarter of ~~2017~~2018 relative to the corresponding period in ~~2016~~2017, primarily driven by production increases ~~primarilyas a result of~~in the ~~Bakken decrease.~~Midland and Delaware Basins (the "Midland/Delaware"), the Bakken/Three Forks play and the Eagle Ford Shale play. Our ~~mineral-and-royalty-interest~~mineral and royalty interest oil and condensate volumes accounted for ~~78.0%~~90% and ~~74.0%~~78% of total oil and condensate volumes for the quarters ended September 30, ~~2017~~2018 and ~~2016,~~2017, respectively.~~The decrease in production volumes was partially offset by an increase in commodity prices between the comparative periods.~~

Natural gas and natural gas liquids sales. Natural gas and NGL sales ~~increased for~~during the current quarter ~~ended September 30,~~were higher than the third quarter of 2017 ~~as compared~~primarily due to ~~the same period for 2016. Higher commodity prices and higher~~increased production volumes, largely ~~driven by new wells~~ in the ~~Haynesville~~Haynesville/Bossier play, ~~were primarily responsible for~~as well as the ~~increase in our natural gas~~Midland/Delaware and ~~NGL revenues. Mineral-and-royalty-interest~~the Bakken/Three Forks play. Mineral and royalty interest production accounted for ~~50.6%~~60% and ~~58.4%~~51% of our natural gas volumes for the quarters ended September 30, 2018 and 2017, ~~and 2016,~~ respectively. There was also an increase in commodity prices between the comparative periods.

Gain (loss) on commodity derivative instruments. During the third quarter of ~~2017,~~2018, we recognized ~~$9.5 million of losses~~an increased loss from ~~oil~~our commodity ~~contracts, which included cash received of $4.0 million,~~derivative instruments compared to ~~recognized gains of $3.7 million in~~ the same period ~~of 2016. During~~in 2017. 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 ~~third quarter of 2017, we recognized $0.2 million of gains from natural gas commodity contracts, which included cash received of $1.0 million, compared to recognized gains of $4.1 million in~~relationships between contract prices and the ~~same period of 2016.~~associated forward curves.

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 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 third quarter of 2018 was slightly higher than the same period of 2017. Leasing activity in the ~~Anadarko~~Austin Chalk, Bakken/Three Forks, Marmaton and ~~Delaware Basins~~Wilcox/Yegua trends made up the majority of lease bonus revenue in the third quarter of ~~2017, while a substantial portion of third quarter 2016 activity came from the Wolfcamp and Marcellus trends.~~2018.

Operating and Other Expenses

Lease operating expense. Lease operating expense includes normally 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 September 30, ~~2017~~2018 as compared to the same period in ~~2016,~~2017, primarily due to ~~decreased operating costs~~lower workover and other service-related expenses on wells in ~~fields reaching economic limits and fewer remedial projects initiated by our operators. These cost decreases were partially offset by increased operating costs in the Haynesville play.~~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 September 30, ~~2017,~~2018, production costs and ad valorem taxes increased ~~from~~as compared to the quarter ended September 30, ~~2016,~~2017, generally as a result of ~~higher~~increased oil and condensate and natural gas ~~prices~~production volumes, as well as higher oil and ~~natural gas production volumes. In addition, the 2016 amount includes $2.7 million of lawsuit settlement proceeds related to improper cost deductions.~~condensate 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 ~~increased slightly~~ for the three months ended September 30, 2018 related to additional costs for the PepperJack B#1 well. Exploration expense for the quarter ended September 30, 2017 ~~as compared to the same period in 2016. The 2017 and 2016 expense represents delay rental~~represented costs incurred to ~~extend working interest leases beyond the original lease term.~~acquire 3-D seismic information related to our mineral and royalty interests from a third-party service provider.

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 ~~increased slightly~~was relatively flat for the quarter ended September 30, ~~2017~~2018 as compared to the same period in ~~2016,~~2017, primarily due to the impact of higher production partially offset by lower depletion rates.

~~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 carrying amounts of property acquisitions, successful exploratory wells, development activity, undeveloped leasehold, and mineral interests to identify impairments. There were no impairments for the quarters ended September 30, 2017 or 2016.

General and administrative. General and administrative expenses are costs not directly associated with the production of oil and natural gas and ~~includes~~include expenses such as the cost of employee salaries and related benefits, office expenses, and fees for professional services. For the quarter ended September 30, ~~2017,~~2018, general and administrative expenses increased as

compared to the same period in ~~2016,~~2017, primarily ~~driven~~due to higher costs associated with our incentive compensation plans period over period, partially offset by lower brokerage and legal fees associated with ~~higher~~our acquisition ~~activity as compared to the correspondingperiodin 2016.~~activity.

Interest expense. Interest expense was higher in the third quarter of ~~2017~~2018 due to increased borrowings under our credit ~~facility.~~facility and higher interest rates. Average outstanding borrowings during the third quarter of ~~2017~~2018 were higher than the third quarter of ~~2016~~2017 primarily due to funding of acquisitions in ~~2017 and 2016, common unit repurchases in 2016, and redemptions associated with our preferred units.~~2018 compared to 2017.

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.~~equity and debt. Our primary uses of cash are for distributions to our unitholders 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.

The Board has adopted a policy pursuant to which distributions equal in amount to no less than the applicable minimum quarterly distribution will be paid on each common and subordinated 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 and subordinated units quarterly or on any other basis, at the applicable minimum quarterly distribution rate or at any other rate, and there is no guarantee that we will pay distributions to our common and subordinated unitholders in any quarter. Our minimum quarterly distribution provides the common unitholders a specified priority right to distributions over the subordinated unitholders. The Board may change the foregoing distribution policy at any time and from time to time.

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 ~~external~~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. Like a number of other master limited partnerships, we are required by our partnership agreement to retain cash from our operations in an amount equal to our estimated replacement capital requirements. ~~The~~On April 27, 2018, the Board ~~of Directors of our general partner (the “Board”) established~~approved a replacement capital expenditure estimate of ~~$15.0~~$11.0 million for the period of April 1, ~~2016~~2018 to March 31, ~~2017. On June 8, 2017, the Board established a replacement capital expenditure estimate of $13.0 million for the period of April 1, 2017 to March 31, 2018.~~

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. ~~Our~~The increase in cash flows from operations was primarily due to higher commodity revenue driven by increased ~~from $141.6 million~~oil and natural gas production and higher realized commodity prices period over period, partially offset by the net cash paid on settlement of commodity derivative instruments for the nine months ended September 30, ~~2016~~2018 compared to ~~$211.7 million~~cash received for the ~~nine months ended September 30,~~same period of 2017. ~~The increase was primarily due to increased commodity revenue driven by higher oil and natural gas sales, an increase in lease bonus and other income, as well as changes in working capital.~~

Investing Activities. Net cash used in investing activities ~~decreased by $87.3 million~~increased in the first nine months of ~~2017~~2018 as compared to the corresponding period in ~~2016~~2017. The increase was primarily due to ~~the~~more cash ~~portion of 2017 mineral~~spent on acquisitions and ~~property acquisitions being lower than the cash portion of 2016 mineral~~additions to oil and ~~property acquisitions during the first nine months of 2016. Lower capital expenditures for~~natural gas properties, partially offset by higher proceeds received from our ~~working interest properties also contributed to the overall decrease in investing activities.~~farmout agreements.

Financing Activities. Cash flows used in financing activities for the nine months ended September 30, ~~2017 were~~2018 increased primarily ~~driven by $142.6 million of~~due to increased distributions to common and subordinated unitholders, distributions to ~~redeemable preferred unitholders~~holders of ~~$3.1 million, redemptions of redeemable~~Series B cumulative convertible preferred units, and increased repayments of ~~$19.6 million, and repurchases of common and subordinated units of $7.8 million,~~borrowings under our credit facility, which ~~were~~was partially offset by ~~net borrowings on our credit facility of $46.0 million and~~increased proceeds from the issuance of our common units ~~pursuant to the ATM Program~~and decreased redemptions of ~~$31.3 million.~~Series A redeemable preferred units.

Development Capital Expenditures

Our ~~2017 drilling expenditures, net of farmout reimbursements, are expected to be between $50~~2018 total development capital expenditure budget is estimated at $45.0 million to ~~$60~~$50.0 million, ~~with almost our entire drilling capital budget allocated to the Haynesville/Bossier play. Due to the timing~~ of cash calls and invoices received from the operators of our Haynesville/Bossier properties, cash payments for our share of drilling and completion activities may vary materially from quarter to quarter. Accordingly, a portion of our 2017 capital budget may ultimately be paid during the first half of 2018.

~~On February 16, 2017, we entered into a farmout agreement covering our working interests within an approximate 34,000-acre block~~which $45.7 million has been invested in ~~San Augustine County, Texas, which will reduce our future capital requirements and will generate additional royalty income.~~

~~During~~ the nine months ended September 30, ~~2017,~~2018. The largest component of this budget relates to our

working-interest participation program in certain Haynesville/Bossier wells in the Shelby Trough area of East Texas. In the first nine months of 2018, we ~~incurred $41.4~~spent $29.2 million in this program, net of farmout reimbursements, related to completions in wells which were spud prior to the farmouts. We do not expect to incur any additional capital expenditures in this program for the remainder of 2018, net of farmout reimbursements. In the PepperJack prospect area, we spent approximately $11.9 million during the nine months ended September 30, 2018 to drill and log two wells targeting the Lower Wilcox formation. We expect to incur an additional $0.5 million to $0.7 million related to ~~drilling and~~the completion costs ~~primarily~~for the PepperJack A#1 well in the ~~Haynesville/Bossier play,~~fourth quarter of 2018.

As a result of our legacy working-interest participation program, we regularly have minor miscellaneous capital expenditures related to workovers/recompletions, leases, and ~~completed~~minor infrastructure projects. Given their nature, the amount and timing of capital to be invested in these types of projects is difficult to forecast; as such, we expect that we will invest approximately $1.0 million to $2.0 million on similar projects for the fourth quarter of 2018.

Acquisitions

We spent approximately $106.4 million and issued common units valued at $22.5 million during the nine months ended September 30, 2018 related to acquisitions of mineral and royalty interests, ~~acquisitions for $160.7 million in cash~~which also included proved oil and ~~equity.~~natural gas properties. See Note 4 – ~~Acquisitions~~Oil and ~~Dispositions~~Natural Gas Properties Acquisitions to our unaudited consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q for further discussion.

Credit Facility

~~On January 23, 2015, we amended and restated~~Pursuant to our $1.0 billion senior secured revolving credit ~~agreement. Under this credit facility,~~agreement, 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. ~~On October 28, 2015, the third amended and restated credit facility was further amended to extend the term of the agreement from February 3, 2017 to February 4, 2019.~~ Borrowings under the ~~third amended and restated~~ credit facility may be used for the acquisition of properties, cash distributions, and other general corporate purposes. Our regular, semi-annual borrowing base redetermination process resulted in a decrease of the borrowing base from $550.0 million to $450.0 million, effective April 15, 2016. Our fall 2016 borrowing base redetermination process resulted in an increase in the borrowing base to $500.0 million, which became effective October 31, 2016. Effective April 25, 2017, the borrowing base redetermination resulted in an increase to $550.0 million. On November 1, 2017, we ~~amended~~entered into the Fourth Amended and ~~restated the credit agreement again~~Restated Credit Agreement to extend the maturity date ~~thereof~~ for a term of five years, create a swingline facility that permits short-term borrowings on same-day notice, and make other changes to the hedging and restrictive covenants. ~~There~~The borrowing base was ~~no change~~reconfirmed at $550.0 million with our fall 2017 redetermination, was increased to ~~the borrowing base.~~$600.0 million effective May 4, 2018 with our spring 2018 redetermination, and was further increased to $675.0 million effective October 31, 2018 with our fall 2018 redetermination. Our credit facility ~~now~~ terminates on November 1, 2022. As of September 30, ~~2017,~~2018, we had outstanding borrowings of ~~$362.0~~$402.0 million at a weighted-average interest rate of ~~3.74%~~4.75%.

The borrowing base ~~under both the third amended and restated credit agreement and the fourth amended and restated credit agreement~~ 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 of two-thirds of the lenders) each have discretion to have the borrowing base redetermined once between scheduled redeterminations. Under the ~~fourth amended~~Fourth Amended and ~~restated credit agreement,~~Restated Credit Agreement, we additionally 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.

Outstanding borrowings under the ~~third amended and restated credit agreement and the fourth amended and restated~~ credit agreement 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,~~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. Through October 2016, the applicable margin ranged from 0.50% to 1.50% in the case of the alternative base rate and from 1.50% to 2.50% in the case of LIBOR, in each case depending on the amount of borrowings outstanding in relation to the borrowing base. Subsequent to the closing of our fall redetermination on October 31, 2016, theThe applicable margin ranges from 1.00% to 2.00% in the case of the alternative base rate and from 2.00% to 3.00% in the case of LIBOR, depending on the borrowings outstanding in relation to the borrowing base. Effective October 31, 2018, the applicable margin for LIBOR was reduced to between 1.75% and 2.75% and the applicable margin for the alternative base rate was reduced to between 0.75% and 1.75%.

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. ~~Under both the third amended and restated credit agreement and the fourth amended and restated credit agreement, our~~Our credit facility is secured by liens on substantially all of our producing properties.

~~Before and after the amendment and restatement that took place on November 1, 2017, our~~

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 ~~swap~~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 ~~modified~~ 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 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 September 30, ~~2017,~~2018, we were in compliance with all debt covenants.

Contractual Obligations

As of September 30, ~~2017,~~2018, there have been no material changes to our contractual obligations previously disclosed in our ~~2016~~2017 Annual Report on Form 10-K.

Off-Balance Sheet Arrangements

As of September 30, ~~2017,~~2018, we did not have any material off-balance sheet arrangements.

Critical Accounting Policies and Related Estimates

As of September 30, ~~2017,~~2018, there have been no significant changes to our critical accounting policies and related estimates previously disclosed in our ~~2016~~2017 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 consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.


~~Item 3.~~	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 ~~natural gas liquids~~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 ~~natural gas liquids~~NGLs have been volatile for several years, 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 – ~~Derivatives and~~Commodity Derivative Financial Instruments and Note 6 – Fair Value ~~Measurement~~Measurements to the unaudited consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q for additional information.

~~Commodity prices have declined in recent years.~~ To estimate the effect lower prices would have on our reserves, we ~~applied a 10% discount to~~reduced the SEC commodity pricing for the ~~twelve~~nine months ended September 30, ~~2017. Applying this discount~~2018 by 10%. This results in an approximate ~~1.6%~~2% reduction of proved reserve volumes as compared to the ~~undiscounted~~unadjusted September 30, ~~2017~~2018 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 September 30, ~~2017,~~2018, we had ~~nine~~ten counterparties, all of which ~~are~~were rated Baa1 or better by Moody’s. ~~Seven~~As of September 30, 2018, nine of our counterparties 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 September 30, ~~2017,~~2018, we had ~~$362.0~~$402.0 million of outstanding borrowings under our credit facility, bearing interest at a weighted-average interest rate of ~~3.74%~~4.75%. 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 ~~$2.7~~$3.0 million for the nine months ended September 30, ~~2017,~~2018, 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.~~	Item 4. Controls and Procedures

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 September 30, ~~2017.~~2018.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the quarter ended September 30, ~~2017~~2018 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION
