measurements to certain assets and liabilities.  Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction

risks inherent in valuation techniques and inputs to valuations.  Fair value measurements assume that the transaction occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability (the market for which the reporting entity would be able to maximize the amount received or minimize the amount paid).  Valuation </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">techniques used in our fair value measurements are based upon observable and

Goodwill is not amortized, but instead is evaluated for impairment periodically. We evaluate goodwill for impairment annually on November 30th, or more often if events or circumstances indicate that goodwill might be impaired. The reporting unit or units used to evaluate and measure goodwill for impairment are determined primarily from the manner in which the business is managed or operated. A reporting unit is an operating segment or a component that is one level below an operating segment. During 2020, we recognized an impairment charge of $132.0 million consisting of the total carrying amount of goodwill allocated to our Hamilton reporting unit.  See Note 5 – Goodwill Impairment for more information.  There were no impairments of goodwill during 2021 or 2019.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><i style="font-style:italic;">Property, Plant and Equipment</i>—Expenditures which extend the useful lives of existing plant and equipment assets are capitalized.  Interest costs associated with major asset additions are capitalized during the construction period.  Maintenance and repairs that do not extend the useful life or increase productivity of the asset are charged to operating expense as incurred.  Exploration expenditures are charged to operating expense as incurred, including costs related to drilling and study costs incurred to convert or upgrade mineral resources to reserves. Land, machinery and equipment under finance lease agreements are capitalized and amortized over the useful lives of the assets given that in each case, ownership transfers at the end of the lease term.  Preparation plants, processing facilities and mineral rights, assuming current production estimates, are depreciated or depleted using the units-of-production method over a range from 1 to 29 years.  Mining equipment and other plant and equipment assets are depreciated principally using the straight-line method over the estimated useful lives of the assets, ranging from 1 to 29 years, limited by the remaining estimated life of each </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">mine.  Depreciable lives for buildings, office equipment and improvements range from 1 to 29 years. Gains or losses arising from retirements are included in operating expenses.  Depletion of coal mineral rights is provided on the basis of tonnage mined in relation to estimated recoverable tonnage, which equals estimated proven and probable coal mineral reserves. Therefore, our coal mineral rights are depleted based on only proven and probable coal mineral reserves.

The lease term includes all noncancelable periods defined in the lease as well as periods covered by options to extend the lease that we are reasonably certain to exercise.  As an implicit borrowing rate cannot be determined under most of our leases, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;">Expenses related to leases determined to be operating leases will be recognized on a straight-line basis over the lease term including any reasonably assured renewal periods, while those determined to be finance leases will be recognized following a front-loaded expense profile in which interest and amortization are presented separately in the income statement.  The determination of whether a lease is accounted for as a finance lease or an operating lease requires management to make estimates primarily about the fair value of the asset and its estimated economic useful life.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><i style="font-style:italic;">Long-Lived Asset Impairment</i>—We review the carrying value of long-lived assets and certain identifiable intangibles whenever events or changes in circumstances indicate that the carrying amount may not be recoverable based upon estimated undiscounted future cash flows.  To the extent the carrying amount is not recoverable, the amount of impairment is measured by the difference between the carrying value and the fair value of the asset (See Note 4 – Long-Lived Asset Impairments).</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><span style="font-style:italic;visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><i style="font-style:italic;">Oil & Gas Reserve Quantities and Carrying Amounts</i>—We are wholly dependent on third-party operators to explore, develop, produce and operate the properties associated with our mineral interests.  We follow the successful efforts method of accounting for our oil & gas mineral interests. Under this method, costs to acquire mineral interests in oil & gas properties are capitalized when incurred. The costs of mineral interests in unproved properties are capitalized pending the results of exploration and leasing efforts by operators. As mineral interests in unproved properties are determined to be proved, the related costs are transferred to proved oil & gas properties. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;">Mineral interests in oil & gas properties are grouped using a reasonable aggregation of properties with a common geological structural feature or stratigraphic condition, which we may also refer to as a depletable group. Mineral interests in proved oil & gas properties are depleted based on the units-of-production method.  Proved reserves are quantities of oil & gas that can be estimated with reasonable certainty to be recoverable in the future from a given date forward, from known reservoirs, under existing economic conditions, operating methods, and government regulations.  Proved developed </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">resources are the quantities expected to be recovered through our operators' existing wells with existing equipment, infrastructure and operating methods.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;">We evaluate impairment of our oil & gas mineral interests in proved properties whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. This evaluation is performed on a depletable group basis. We compare the undiscounted projected future cash flows expected in connection with a depletable group to its unamortized carrying amount to determine recoverability. When the carrying amount of a depletable group exceeds its estimated undiscounted future cash flows, the carrying amount is written down to its fair value, which is measured as the present value of the projected future cash flows of such properties. The factors used to determine fair value include estimates of proved reserves, future commodity prices, timing of future production, future expenditures, and a risk-adjusted discount rate.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;">Our oil & gas mineral interests in unproved properties are also assessed for impairment periodically but at least annually when facts and circumstances indicate that the unproved property will not be transferred to proved properties.  Impairment of individual unproved properties whose acquisition costs are relatively significant are assessed on a property-by-property basis, and an impairment loss is recognized if we determine that the unproved property will not be transferred to proved properties.  Impairment of unproved properties whose acquisition costs are not individually significant are assessed on a group basis. Any amount of loss to be recognized and the amount of a valuation allowance needed to provide for impairment of those properties is determined by amortizing those properties in the aggregate on the basis of historical experience and other relevant information, such as the relative proportion of such properties on which proved reserves have been found in the past.  </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;">Upon the sale of a complete depletable group, the book value thereof, less proceeds or salvage value, are charged to income. Upon the sale or retirement of an aggregation of interests which make up less than a complete depletable group, the proceeds are credited to accumulated depreciation, depletion and amortization, unless doing so would significantly alter the depreciation, depletion and amortization rate of the depletable group, in which case a gain or loss would be recorded.</p><p style="font-family:'Times New

operations are governed by various state statutes and the Federal Surface Mining Control and Reclamation Act of 1977, which establish reclamation and mine closing standards. These regulations require, among other things, restoration of property in accordance with specified standards and an approved reclamation plan.  We record a liability for the fair value of the estimated cost of future mine asset retirement and closing procedures, escalated for inflation then discounted, on a present value basis in the period incurred or acquired and a corresponding amount is capitalized by increasing the carrying amount of the related long-lived asset. Those costs relate to permanently sealing portals at underground mines and to reclaiming the final pits and support surface acreage for both our underground mines and past surface mines. Examples of these types of costs, common to both types of mining, include, but are not limited to, removing or covering refuse piles and settling ponds, water treatment obligations, and dismantling preparation plants, other facilities and roadway infrastructure.  Accounting for asset retirement obligations also requires depreciation of the capitalized asset retirement cost and accretion of the asset retirement obligation over time.  The depreciation is generally determined on a units-of-production basis and accretion is generally recognized over the life of the producing assets. As changes in estimates occur (such as mine plan revisions, changes in estimated costs or changes in timing of the performance of reclamation activities), the revisions to the obligation and asset are recognized at the appropriate credit-adjusted, risk-free interest rate.  Federal and state laws require bonds to secure our obligations to reclaim lands used for mining and are typically renewable on a yearly basis.  See Note 19 – Asset Retirement Obligations for more information.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><i style="font-style:italic;">Pension Benefits</i>—The funded status of our pension benefit plan is recognized separately in our consolidated balance sheets as either an asset or liability.

which primarily relate to sales of thermal coal, are recognized at the point in time when control of the coal passes to the customer.  We have determined that each ton of coal represents a separate and distinct performance obligation.  Our coal supply contracts and other revenue contracts vary in length from short-term to long-term sales contracts and do not typically have significant financing components.  Transportation revenues represent the fulfillment costs incurred for the services provided to customers through third-party carriers and for which we are directly reimbursed.  Other revenues primarily consist of transloading fees, administrative service revenues from our affiliates, mine safety services and products, other coal contract fees and other handling and service fees.  Performance obligations under these contracts are typically satisfied upon transfer of control of the goods or services to our customer which is determined by the contract and could be upon shipment or upon delivery.  </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;">The estimated transaction price from each of our contracts is based on the total amount of consideration we expect to be entitled to under the contract.  Included in the transaction price for certain coal supply contracts is the impact of variable consideration, including quality price adjustments, handling services, government imposition claims, per ton price fluctuations based on certain coal sales price indices and anticipated payments in lieu of shipments.  We have constrained the expected value of variable consideration in our estimation of transaction price and only included this consideration to the extent that it is probable that a significant revenue reversal will not occur.  The estimated transaction price for each contract is allocated to our performance obligations based on relative standalone selling prices determined at contract inception.  Variable consideration is allocated to a specific part of the contract in many instances, such as if the variable consideration is based on production activities for coal delivered during a certain period or the outcome of a customer's ability to accept coal shipments over a certain period. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;">Contract assets are recorded as trade receivables and reported separately in our consolidated balance sheet from other contract assets as title passes to the customer and our right to consideration becomes unconditional.  Payments for coal shipments are typically due within <span

performance.  We typically do not have material contract assets that are stated separately from trade receivables as our performance obligations are satisfied as control of the goods or </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">services passes to the customer thereby granting us an unconditional right to receive consideration.  Contract liabilities relate to consideration received in advance of the satisfaction of our performance obligations.  Contract liabilities are recognized as revenue at the point in time when control of the good or service passes to the customer.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><span

Revenue Recognition</i>—Oil & gas royalty revenues are recognized at the point in time when control of the product is transferred to the purchaser by the lessee and collectability of the sales price is reasonably assured. Oil & gas are priced on the delivery date based upon prevailing market prices with certain adjustments related to oil quality and physical location. The royalty we receive is tied to a market index, with certain adjustments based on, among other factors, whether a well connects to a gathering or transmission line, quality and heat content of the product, and prevailing supply and demand conditions.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;">We also periodically earn revenue from lease bonuses. We recognize lease bonus revenue when we execute a lease of our mineral interests to exploration and production companies. A lease agreement represents our contract with an operator, which is generally an exploration and production company.  The contract will (a) generally transfer the rights to any oil or gas discovered, (b) grant us a right to a specified royalty interest from the operator, and (c) require the operator to commence drilling and complete operations within a specified time period. Control of the minerals transfers to the operator when the lease agreement is executed.  At the time we execute the lease agreement, we expect to receive the lease bonus payment within a reasonable time, though in no case more than one year, such that we do not adjust the expected amount of consideration for the effects of any significant financing component. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;">As a non-operator, we have limited visibility into the timing of when new wells start producing.  In addition, production statements may not be received for 30 to 90 days or more after the date production is delivered. As a result, we are 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 from our properties are estimated and recorded within the <i style="font-style:italic;">Trade receivables</i> line item in our consolidated balance sheets.  The difference between our estimates and the actual amounts received for oil & gas royalty revenue are immaterial and recorded in the month that payment is received from the third-party purchaser unless new production information is received prior to the payment allowing us to update the estimate recorded.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><i style="font-style:italic;">Common Unit-Based Compensation</i>—We have the Long-Term Incentive Plan ("LTIP") for certain employees and officers of MGP and its affiliates who perform services for us.  As part of the LTIP, unit awards of non-vested "phantom" or notional units, also referred to as "restricted units", may be granted which upon satisfaction of time and performance-based vesting requirements, entitle the LTIP participant to receive ARLP common units.  Certain awards may also contain a minimum-value guarantee payable in ARLP common units or cash that would be paid regardless of whether or not the awards vest, as long as service requirements are met.  Annual grant levels, vesting provisions and minimum-value guarantees of restricted units for designated participants are recommended by Mr. Craft, subject to review and approval of the compensation committee of our general partner ("Compensation Committee").  Vesting of all restricted units outstanding is subject to the satisfaction of certain financial tests.  If it is not probable the financial tests for a particular grant of restricted units will be met, any previously expensed amounts for that grant are reversed and no future expense will be recognized for that grant.  Assuming the financial tests are met, grants of restricted units issued to LTIP participants are generally expected to cliff vest on January 1st of the third year following issuance of the grants.  We expect to settle restricted unit grants by delivery of newly-issued ARLP common units, except for the portion of the grants that will satisfy employee tax withholding obligations of LTIP participants.  We account for forfeitures of non-vested LTIP restricted unit grants as they occur.  As provided under the distribution equivalent rights ("DERs") provisions of the LTIP and the terms of the LTIP restricted unit awards, all non-vested restricted units include contingent rights to receive quarterly distributions in cash or, at the discretion of the Compensation Committee, phantom units in lieu of cash credited to a bookkeeping account with value equal to the cash distributions we make to unitholders during the vesting period. If it is not probable the financial tests for a particular grant of restricted units will be met, any previously paid DER amounts for that grant are reversed from Partners’ Capital and recorded as compensation expense and any future DERs, for that grant, if any, will be recognized as compensation expense when paid.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;">We utilize the Supplemental Executive Retirement Plan ("SERP") to provide deferred compensation benefits for certain officers and key employees. All allocations made to participants under the SERP are made in the form of "phantom" ARLP units and SERP distributions will be settled in the form of ARLP common units.  The SERP is administered by the Compensation Committee.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;">Our directors participate in the MGP Amended and Restated Deferred Compensation Plan for Directors ("Directors' Deferred Compensation Plan"). Pursuant to the Directors' Deferred Compensation Plan, for amounts deferred either automatically or at the election of the director, a notional account is established and credited with notional common units of ARLP, described in the Directors' Deferred Compensation Plan as "phantom" units.  Distributions from the Directors' Deferred Compensation Plan will be settled in the form of ARLP common units.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;">For both the SERP and Directors' Deferred Compensation Plan, when quarterly cash distributions are made with respect to ARLP common units, an amount equal to such quarterly distribution is credited to each participant's notional account as additional phantom units.  All grants of phantom units under the SERP and Directors' Deferred Compensation Plan vest immediately.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;">The fair value of restricted common unit grants under the LTIP, SERP and the Directors' Deferred Compensation Plan are determined on the grant date of the award and recognized as compensation expense on a pro rata basis for LTIP and SERP awards, as appropriate, over the requisite service period. Compensation expense is fully recognized on the grant date for quarterly distributions credited to SERP accounts and Directors' Deferred Compensation Plan awards. The corresponding liability is classified as equity and included in limited partners' capital in the consolidated financial statements (See Note 17 – Common Unit-Based Compensation Plans).</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:20pt;margin:0pt;"><i style="font-style:italic;">Income Taxes</i>—We are not a taxable entity for federal or state income tax purposes; the tax effect of our activities accrues to the unitholders. Although publicly traded partnerships as a general rule will be taxed as corporations, we qualify for an exemption because at least 90% of our income consists of qualifying income, as defined in Section 7704(c) of the Internal Revenue Code.  Net income for financial statement purposes may differ significantly from taxable income reportable to unitholders as a result of differences between the tax basis and financial reporting basis of assets and liabilities and the taxable income allocation requirements under our partnership agreement. Individual unitholders have different investment bases depending upon the timing and price of acquisition of their partnership units. Furthermore, each unitholder's tax accounting, which is partially dependent upon the unitholder's tax position, differs from the accounting followed in our consolidated financial statements.  Accordingly, the aggregate difference in the basis of our net assets for financial and tax reporting purposes cannot be readily determined because information regarding each unitholder's tax attributes in our partnership is not available to us. We have certain subsidiaries that are subject to federal and state income taxes.  These income taxes are not material to our financial position or results of operations.  </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><i style="font-style:italic;">New Accounting Standards Issued and Not Yet Adopted</i>—In November 2021, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2021-10, Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance ("ASU 2021-10").  ASU 2021-10 increases the transparency of government assistance including the disclosure of (1) the types of assistance, (2) an entity’s accounting for the assistance, and (3) the effect of the assistance on an entity’s financial statements.  ASU 2021-10 is effective for fiscal years beginning after December 15, 2021, with early adoption permitted.  The adoption of ASU 2021-10 will not have a material impact on our consolidated financial statements.</p>

We assess the recoverability of royalty prepayments based on estimated future production. Royalty prepayments estimated to be nonrecoverable are expensed.  Our <i style="font-style:italic;">Advance royalties</i> are summarized as follows:</p><p style="font-family:'Times New

These regulations require, among other things, restoration of property in accordance with specified standards and an approved reclamation plan.  We record a liability for the fair value of the estimated cost of future mine asset retirement and closing procedures, escalated for inflation then discounted, on a present value basis in the period incurred or acquired and a corresponding amount is capitalized by increasing the carrying amount of the related long-lived asset. Those costs relate to permanently sealing portals at underground mines and to reclaiming the final pits and support surface acreage for both our underground mines and past surface mines. Examples of these types of costs, common to both types of mining, include, but are not limited to, removing or covering refuse piles and settling ponds, water treatment obligations, and dismantling preparation plants, other facilities and roadway infrastructure.  Accounting for asset retirement obligations also requires depreciation of the capitalized asset retirement cost and accretion of the asset retirement obligation over time.  The depreciation is generally determined on a units-of-production basis and accretion is generally recognized over the life of the producing assets. As changes in estimates occur (such as mine plan revisions, changes in estimated costs or changes in timing of the performance of reclamation activities), the revisions to the obligation and asset are recognized at the appropriate credit-adjusted, risk-free interest rate.  Federal and state laws require bonds to secure our obligations to reclaim lands used for mining and are typically renewable on a yearly basis.  See Note 19 – Asset Retirement Obligations for more information.</p>

Oil & gas are priced on the delivery date based upon prevailing market prices with certain adjustments related to oil quality and physical location. The royalty we receive is tied to a market index, with certain adjustments based on, among other factors, whether a well connects to a gathering or transmission line, quality and heat content of the product, and prevailing supply and demand conditions.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;">We also periodically earn revenue from lease bonuses. We recognize lease bonus revenue when we execute a lease of our mineral interests to exploration and production companies. A lease agreement represents our contract with an operator, which is generally an exploration and production company.  The contract will (a) generally transfer the rights to any oil or gas discovered, (b) grant us a right to a specified royalty interest from the operator, and (c) require the operator to commence drilling and complete operations within a specified time period. Control of the minerals transfers to the operator when the lease agreement is executed.  At the time we execute the lease agreement, we expect to receive the lease bonus payment within a reasonable time, though in no case more than one year, such that we do not adjust the expected amount of consideration for the effects of any significant financing component. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;">As a non-operator, we have limited visibility into the timing of when new wells start producing.  In addition, production statements may not be received for 30 to 90 days or more after the date production is delivered. As a result, we are 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 from our properties are estimated and recorded within the <i style="font-style:italic;">Trade receivables</i> line item in our consolidated balance sheets.  The difference between our estimates and the actual amounts received for oil & gas royalty revenue are immaterial and recorded in the month that payment is received from the third-party purchaser unless new production information is received prior to the payment allowing us to update the estimate recorded.</p>

If it is not probable the financial tests for a particular grant of restricted units will be met, any previously paid DER amounts for that grant are reversed from Partners’ Capital and recorded as compensation expense and any future DERs, for that grant, if any, will be recognized as compensation expense when paid.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;">We utilize the Supplemental Executive Retirement Plan ("SERP") to provide deferred compensation benefits for certain officers and key employees. All allocations made to participants under the SERP are made in the form of "phantom" ARLP units and SERP distributions will be settled in the form of ARLP common units.  The SERP is administered by the Compensation Committee.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;">Our directors participate in the MGP Amended and Restated Deferred Compensation Plan for Directors ("Directors' Deferred Compensation Plan"). Pursuant to the Directors' Deferred Compensation Plan, for amounts deferred either automatically or at the election of the director, a notional account is established and credited with notional common units of ARLP, described in the Directors' Deferred Compensation Plan as "phantom" units.  Distributions from the Directors' Deferred Compensation Plan will be settled in the form of ARLP common units.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;">For both the SERP and Directors' Deferred Compensation Plan, when quarterly cash distributions are made with respect to ARLP common units, an amount equal to such quarterly distribution is credited to each participant's notional account as additional phantom units.  All grants of phantom units under the SERP and Directors' Deferred Compensation Plan vest immediately.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;">The fair value of restricted common unit grants under the LTIP, SERP and the Directors' Deferred Compensation Plan are determined on the grant date of the award and recognized as compensation expense on a pro rata basis for LTIP and SERP awards, as appropriate, over the requisite service period. Compensation expense is fully recognized on the grant date for quarterly distributions credited to SERP accounts and Directors' Deferred Compensation Plan awards. The corresponding liability is classified as equity and included in limited partners' capital in the consolidated financial statements (See Note 17 – Common Unit-Based Compensation Plans).</p>

Although publicly traded partnerships as a general rule will be taxed as corporations, we qualify for an exemption because at least 90% of our income consists of qualifying income, as defined in Section 7704(c) of the Internal Revenue Code.  Net income for financial statement purposes may differ significantly from taxable income reportable to unitholders as a result of differences between the tax basis and financial reporting basis of assets and liabilities and the taxable income allocation requirements under our partnership agreement. Individual unitholders have different investment bases depending upon the timing and price of acquisition of their partnership units. Furthermore, each unitholder's tax accounting, which is partially dependent upon the unitholder's tax position, differs from the accounting followed in our consolidated financial statements.  Accordingly, the aggregate difference in the basis of our net assets for financial and tax reporting purposes cannot be readily determined because information regarding each unitholder's tax attributes in our partnership is not available to us. We have certain subsidiaries that are subject to federal and state income taxes.  These income taxes are not material to our financial position or results of operations.  </p>

in AllDale I & II and the general partner interests in AllDale I & II for $176.2 million, which was funded with cash on hand and borrowings under the Revolving Credit Facility.  As a result of the AllDale Acquisition and our previous investments held through Cavalier Minerals, we acquired control of approximately 43,000 net royalty acres strategically positioned primarily in the core of the Permian (Delaware and Midland), Anadarko (SCOOP/STACK) and Williston (Bakken) Basins.  The AllDale Acquisition provides us with diversified exposure to industry leading operators and is consistent

discounted cash flow models include estimated production, projected cash flows, forward oil & gas prices and a risk adjusted discount rate.  Certain assumptions used are not observable in active markets, therefore the fair value measurements represent Level 3 fair value measurements.  AllDale I & II's carrying value of the receivables and accounts payable represent their fair value given

9,000 net royalty acres in the Midland Basin for a cash purchase price of $144.9 million.  The purchase price was funded with cash on hand and borrowings under our Revolving Credit Facility discussed in Note 8 – Long-Term Debt.  The Wing Acquisition enhances our ownership position in the Permian Basin, expands our exposure to industry leading operators </p><p style="font-family:'Times New

 Our income approach primarily comprised a discounted cash flow model.  The assumptions used in the discounted cash flow model included estimated production, projected cash flows, forward oil & gas prices and a weighted average cost of capital.  Our market approach consisted of the observation of recent acquisitions in the Permian Basin to determine a market price for similar mineral interests.  Certain assumptions used in our valuation are not observable in active markets; therefore, the fair value measurements represent Level 3 fair value measurements.  The carrying value of the receivables represents the fair value given the short-term nature of the receivables.</p><p style="font-family:'Times New

from Boulders for a purchase price of $31.0 million. This acquisition gives us increased exposure to a prolific area of the Delaware Basin and is within close proximity to reserves acquired in the AllDale and Wing Acquisitions.  The acreage is mostly undeveloped.  Because more than 90% of the mineral interests acquired in the Boulders Acquisition represent undeveloped properties, including proved undeveloped, we have determined that the Boulders Acquisition should be accounted for as an asset acquisition. We have allocated the purchase price to the acquired reserves as follows:</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span

Key assumptions used in our valuation were not observable in active markets; therefore, the fair value measurements represent Level 3 fair value measurements.  The fair value of Hamilton was determined to be below its carrying amount (including goodwill) by more than the recorded balance of goodwill associated with the mine.  Accordingly, we recognized an impairment charge of $132.0 million consisting of the total carrying amount of goodwill associated with Hamilton.  This impairment charge reduced our consolidated goodwill balance to $4.4 million. During the first quarter of 2020, we also performed an interim test on our remaining goodwill balances not associated with Hamilton and concluded no impairment was necessary for our other reporting units.</p>

recorded lower of cost or net realizable value adjustments of $3.2 million to our coal inventories as a result of lower coal sale prices and higher cost per ton due to the impact of lower production on our fixed costs per ton in addition to the impact of challenging market conditions on our production levels.  The lower of cost or net realizable value adjustments reflect the impacts of the challenging market conditions and were primarily attributable to the Mettiki and Hamilton mining complexes.</p><p style="font-family:'Times New

with various financial institutions.  The Credit Agreement provides for a $459.5 million revolving credit facility, including a sublimit of $125 million for the issuance of letters of credit and a sublimit of $15.0 million for swingline borrowings (the "Revolving Credit Facility"), with a termination date of March 9, 2024.  Concurrently with the entry into the Credit Agreement, we reorganized the entities holding our oil & gas interests such that Alliance Royalty, LLC became a direct wholly owned subsidiary of Alliance Minerals.  We incurred debt issuance costs in 2020 of $6.3 million in connection with the Credit Agreement. These debt issuance costs are deferred and amortized as a component of interest expense over the term of the Revolving Credit Facility.  </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;">The Credit Agreement is guaranteed by certain of our Intermediate Partnership's material direct and indirect subsidiaries (the "Restricted Subsidiaries") and is secured by substantially all of the assets of the Restricted Subsidiaries.  The Credit Agreement is also guaranteed by Alliance Minerals but the oil and gas minerals assets of Alliance Minerals and its direct and indirect subsidiaries (collectively with Alliance Minerals, the "Unrestricted Subsidiaries") are not collateral under the Credit Agreement.  Borrowings under the Revolving Credit Facility bear interest, at our option, at either (i) the Base Rate at the greater of three benchmarks or (ii) a Eurodollar Rate, plus margins for (i) or (ii), as applicable, that fluctuate depending upon the ratio of Consolidated Debt to Consolidated Cash Flow (each as defined in the Credit Agreement).  The Eurodollar Rate, with applicable margin, under the Revolving Credit Facility was 2.45% as of December 31, 2021.  At December 31, 2021, we had $44.1 million of letters of credit outstanding with $415.4 million available for borrowing under the Revolving Credit Facility. We incur an annual commitment fee of 0.35% on the undrawn portion of the Revolving Credit Facility.  We utilize the Revolving Credit Facility, as appropriate, for working capital requirements, capital expenditures and investments, scheduled debt payments and distribution payments.  </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;">The Credit Agreement contains various restrictions affecting the Intermediate Partnership and its Restricted Subsidiaries including, among other things, restrictions on incurrence of additional indebtedness and liens, sale of assets, investments, mergers and consolidations and transactions with affiliates, including transactions with Unrestricted Subsidiaries.  In each case, these restrictions are subject to various exceptions.  In addition, the payment of cash distributions is restricted if such payment would result in a fixed charge coverage ratio of less than 1.0 to 1.0 (as defined in the Credit Agreement) for the four most recently ended fiscal quarters.  The Credit Agreement requires the Intermediate Partnership to maintain (a) a debt to cash flow ratio of not more than 2.5 to 1.0, (b) a cash flow to interest expense ratio of not less than 3.0 to 1.0 and (c) a first lien debt to cash flow ratio of not more than 1.5 to 1.0, in each case, during the four most recently ended fiscal quarters. The debt to cash flow ratio, cash flow to interest expense ratio and first lien debt to cash flow ratio were 0.95 to 1.0, 11.91 to 1.0 and 0.10 to 1.0, respectively, for the trailing twelve months ended December 31, 2021.  We remained in compliance with the covenants of the Credit Agreement as of December 31, 2021 and anticipate remaining in compliance with the covenants. </p><p

consolidated subsidiaries’ net assets for which the ability to transfer funds to ARLP in the form of cash dividends, loans, advances, or transfers is restricted.  As a result of the restrictions

Partnership and Alliance Resource Finance Corporation (as co-issuer), a wholly owned subsidiary of the Intermediate Partnership ("Alliance Finance"), issued an aggregate principal amount of $400.0 million of senior unsecured notes due 2025 ("Senior Notes") in a private placement to qualified institutional buyers.  The Senior Notes have a term of eight years, maturing on May 1, 2025 (the "Term") and accrue interest at an annual rate of 7.5%.  Interest is payable semi-annually in arrears on each May 1 and November 1.  The indenture governing the Senior Notes contains customary terms, events of default and covenants relating to, among other things, the incurrence of debt, the payment of distributions or similar restricted payments, undertaking transactions with affiliates and limitations on asset sales.  The issuers of the Senior Notes may redeem all or a part of the notes at any time at redemption prices set forth in the indenture governing the Senior Notes.  </p><p

2014, certain direct and indirect wholly owned subsidiaries of our Intermediate Partnership entered into a $100.0 million accounts receivable securitization facility ("Securitization Facility").  In January 2021, we reduced the borrowing availability under the facility to $60.0 million.  Under the Securitization Facility, certain subsidiaries sell certain trade receivables on an ongoing basis to our Intermediate Partnership, which then sells the trade receivables to AROP Funding, LLC ("AROP Funding"), a wholly owned bankruptcy-remote special purpose subsidiary of our Intermediate Partnership, which in turn borrows on a revolving basis up to $60.0 million secured by the trade receivables.  After the sale, Alliance Coal, as servicer of the assets, collects the receivables on behalf of AROP Funding.  The Securitization Facility bears interest based on a Eurodollar Rate.  The agreement governing the Securitization Facility contains customary terms and conditions, including limitations with regards to certain customer credit ratings.  In January 2022, we extended the term of the Securitization Facility to January 2023.  The Securitization Facility was previously scheduled to mature in January 2022.  At December 31, 2021, we had no outstanding balance under the Securitization Facility.</p><p style="font-family:'Times New

entered into a limited liability company agreement (the "Cavalier Agreement") to create Cavalier Minerals, which was formed to indirectly acquire oil & gas mineral interests through its ownership in AllDale I & II.  Alliance Minerals owns a 96% member interest in Cavalier Minerals, and Bluegrass Minerals owns a 4% member interest in Cavalier Minerals and a profits interest which entitles it to receive distributions equal to 25% of all distributions (including in liquidation) after all members have recovered their investment.  Distributions with respect to Bluegrass Minerals' profits interest will be offset by all distributions received by Bluegrass Minerals from the former general partners of AllDale I & II.  To date, there has been no profits interest distribution.  Bluegrass Minerals was Cavalier Minerals' managing member prior to the AllDale Acquisition (see Note 3 – Acquisitions).  In conjunction with the AllDale Acquisition, we became the managing member in Cavalier Minerals.  Total contributions to and cumulative distributions from Cavalier Minerals are as follows:</p><p style="font-family:'Times New

privately-held company providing large-scale, high-utilization gas compression assets to customers operating primarily in the Permian Basin.  This structured investment provided us with a quarterly cash or payment-in-kind return.  On February 8, 2019, Kodiak redeemed our preferred interest for $135.0 million in cash resulting in an $11.5 million gain due to an early redemption premium. The gain is included in the <i style="font-style:italic;">Equity securities income</i> line item.  We no longer hold any </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">ownership interests in Kodiak.  Prior to the redemption, we accounted for our ownership interests in Kodiak as equity securities without readily determinable fair values.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;">See Note 2 – Summary of Significant Accounting Policies for more information on our accounting policy for investments.</p>

We make matching contributions based on a percent of an employee's eligible compensation and also make an additional non-matching contribution.  Our contribution expense for the PSSP was approximately $17.7 million, $16.1 million and $21.1 million for the years ended December 31, 2021, 2020 and 2019, respectively.</p><p style="font-family:'Times New

compensation expense and any future DERs, for that grant, if any, will be recognized as compensation expense when paid.  </p><p style="font-family:'Times New

million, $8.1 million and $10.4 million, respectively.  LTIP expense for grants of restricted units for the year ended December 31, 2020 includes the impact of the reversal of the 2019 Grants, the modification of the 2020 Grants and </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">incremental compensation cost associated with the cash settlement of the 2018 Grants.  The cash settlement of the 2018 Grants was the first time we have settled restricted units in cash and we currently do not expect to do so again in the future.  The cash settlement of the 2018 Grants resulted in $5.4 million in incremental compensation cost.  The 2019 Grants were determined to be not probable of vesting therefore $4.8 million of cumulative previously recognized expense was reversed in 2020, offset in part by related DERs for the 2019 Grants previously recorded to equity and then expensed in 2020.  The 2020 Grants were determined to be improbable of vesting therefore the Compensation Committee modified the awards to change the vesting requirement, which made the grants probable of vesting, and granted additional restricted units under these modified vesting requirements as previously discussed.  As a result, the grant date fair value of the modified awards was changed to reflect the modification date fair value of the awards resulting in a net reduction in LTIP expense of $1.0 million for the year ended December 31, 2020.</p><p style="font-family:'Times New

Our property insurance was procured from our wholly owned captive insurance company, Wildcat Insurance, LLC ("Wildcat Insurance"). Wildcat Insurance charged certain of our subsidiaries for the premiums on this program and in return purchased reinsurance for the program in the standard market. The maximum limit in the commercial property program is $100.0 million per occurrence, excluding a $1.5 million deductible for property damage, a 75 or 90 day waiting period for underground business interruption depending on the mining complex and an additional $10.0 million overall aggregate deductible. We have elected to retain a 10% participating interest in our commercial property insurance program. We can make no assurances that we will not experience significant insurance claims in the future that could have a material adverse effect on our business, financial condition, results of operations and ability to purchase property insurance in the future. Also, exposures exist for which no insurance may be available and for which we have not reserved. In addition, the insurance industry has been subject to efforts by environmental activists to restrict coverages available for fossil-fuel companies. </p>

Our Coal Royalties reportable segment includes coal mineral reserves and resources owned or leased by Alliance Resource Properties, which are either (a) leased to our mining complexes or (b) near our coal mining operations but not yet leased.  </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;">Beginning in the first quarter of 2021, we began to strategically view and manage our coal royalty activities separately from our coal operations since acquiring and managing a variety of royalty producing assets involve similar attributes.  As a result, we restructured our reportable segments to better reflect this strategic view in how we manage our business and allocate resources.  Prior periods have been recast to include Alliance Resource Properties within our new Coal Royalties reportable segment with offsetting recast adjustments primarily to our coal operations reportable segments and to a lesser extent, our Other, Corporate and Elimination category.  Eliminations reported in Other, Corporate and Elimination were also recast to reflect intercompany royalty revenues and offsetting intercompany royalty expense resulting from our new Coal Royalties reportable segment.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:18pt;margin:0pt;">The Illinois Basin Coal Operations reportable segment includes currently operating mining complexes (a) the Gibson County Coal, LLC's ("Gibson") mining complex, which includes the Gibson South mine, (b) the Warrior Coal, LLC ("Warrior") mining complex, (c) the River View Coal, LLC ("River View") mining complex and (d) the Hamilton mining complex.
