PART I

ITEM 1.

Business

Mewbourne Energy Partners 10-A, L.P. (the “Registrant” or the “Partnership”) is a limited partnership organized under the laws of the State of Delaware on February 9, 2010 (date of inception). Mewbourne Development Corporation (“MD”), a Delaware Corporation, has been appointed as the Registrant’s managing general partner. MD has no significant equity interest in the Registrant.

Limited and general partner interests in the Registrant were offered at $5,000 each to accredited investors in a private placement pursuant to Section 4(2) of the Securities Act of 1933 and Regulation D promulgated thereunder, for a total of $73,000,000 sold. During 2012 all general partner equity interests were converted to limited partner equity interests

The Partnership participates in oil and natural gas activities through a Drilling Program Agreement (the “Program”). The Partnership and MD are parties to the Program Agreement. The Registrant engages primarily in oil and natural gas development and production and is not involved in any other industry segment. The Program is governed by a Drilling Program Agreement between the Registrant, MD and Mewbourne Oil Company (“MOC”), the Program manager and a wholly owned subsidiary of Mewbourne Holdings, Inc., which is also the parent of MD. MD does not make any capital contributions directly to the Registrant; rather, MD makes its capital contributions directly to the Program. See the financial statements in Item 8 of this report for a summary of the Registrant’s revenue, income and identifiable assets.

The sale of crude oil and natural gas produced by the Registrant will be affected by a number of factors that are beyond the Registrant’s control. These factors include the price of crude oil and natural gas, the fluctuating supply of and demand for these products, competitive fuels, refining, transportation, extensive federal and state regulations governing the production and sale of crude oil and natural gas, and other competitive conditions. It is impossible to predict with any certainty the future effect of these factors on the Registrant.

The market for crude oil is such that the Registrant anticipates it will be able to sell all the crude oil it can produce. Natural gas will be sold to natural gas marketers and end users on the spot market. The spot market reflects immediate sales of natural gas without long-term contractual commitments. The future market condition for natural gas cannot be predicted with any certainty, and the Registrant may experience delays in marketing natural gas production and fluctuations in natural gas prices.

Many aspects of the Registrant’s activities are highly competitive including, but not limited to, the acquisition of suitable drilling prospects and the procurement of drilling and related oil field equipment, and are subject to governmental regulation, both at Federal and state levels. The Registrant’s ability to compete depends on its financial resources and on the managing general partner’s staff and facilities, none of which are significant in comparison with those of the oil and natural gas exploration, development, and production industry as a whole. Federal and state regulation of oil and natural gas operations generally includes operational activity, drilling and spacing of wells on producing acreage, the imposition of maximum allowable production rates, the taxation of income and other items, and the protection of the environment.

The Registrant does not have any employees of its own. MD is responsible for all management functions. MOC, a wholly owned subsidiary of Mewbourne Holdings, Inc., which is also the parent of the Registrant’s managing general partner, has been appointed Program Manager and is responsible for activities in accordance with a Drilling Program Agreement entered into by the Registrant, MD and MOC. AtOn March 31, ~~2021~~2022, MOC employed ~~486~~545 persons, many of whom dedicated a part of their time to the conduct of the Registrant’s business during the period for which this report is filed.

The production of oil and natural gas is not considered subject to seasonal factors although the price received by the Registrant for natural gas sales will generally tend to increase during the winter months. Order backlog is not pertinent to the Registrant’s business.

Industry Operating Environment

The oil and natural gas industry is affected by many factors that the Partnership generally cannot control, including the prices of oil, natural gas and natural gas liquids. Global macroeconomic ~~factors~~ factors contributing to uncertainty within the industry include real or perceived geopolitical risks in oil-producing regions of the world, particularly the Middle East; forecasted levels of global economic growth combined with forecasted global supply; supply levels of oil and natural gas due to exploration and development activities in the United States; global health concerns; environmental and climate change regulation; actions taken by the Organization of Petroleum Exporting Countries (“OPEC”); the Russia/Ukraine conflict; and the strength of the U.S. dollar in international currency markets. Natural gas prices vary in accordance with North American supply and demand and are also affected by imports and exports of natural gas liquids. Weather also has a significant impact on demand for natural gas since it is a primary heating source in the United States.

ITEM 2.

Properties

Property Interests

The Registrant’s properties consist primarily of interests in properties on which oil and natural gas wells are located. Such property interests are often subject to landowner royalties, overriding royalties and other oil and natural gas leasehold interests.

Fractional working interests in developmental oil and natural gas prospects, located primarily in the Anadarko Basin of Western Oklahoma, the Texas Panhandle, and the Permian Basin of New Mexico and West Texas, were acquired by the Registrant, resulting in the Registrant’s participation in the drilling of oil and natural gas wells. AtOn December 31, ~~2020~~2021, the Registrant owned working interests in ~~108~~114 producing wells. The Registrant had no drilling ~~activity~~ activity for the years ended December 31, ~~2020~~2021 and ~~2019~~2020. Additional capital costs incurred, if any, were due to maintenance of current wells.

Third Party Review of Reserves Estimate

The reserves estimate shown herein has been independently ~~evaluated~~ evaluated by ~~Forrest~~Legacy A.Petroleum ~~Garb & Associates, Inc~~Engineering. Their reserves estimate is filed with this report as Exhibit 99.1. The qualifications of ~~William~~Stacy M. ~~Donald Harris III~~Light, P.E., the technical person primarily responsible for overseeing ~~his~~her firm’s preparation of the Partnership’s reserve estimates are set forth below.

• Over 3024 years of practical experience in petroleum engineering

• Registered professional engineer in the state of Texas

• Bachelor of Science Degree in Petroleum Engineering

Master of Business Administration

Internal Controls Over Reserves Estimate

MD, the Registrant’s managing general partner, maintains internal controls such as the following to ensure the reliability of reserves estimation:

• No employee’s compensation is tied to the amount of reserves booked.

• Comprehensive Securities and Exchange Commission (“SEC”) compliant internal policies are followed to determine and report proved reserves.

• Reserves estimate is made by experienced reservoir engineers or under their direct supervision.

• The reservoir engineers review all the Partnership’s reported proved reserves at the close of each quarter.

ITEM 3.

Legal Proceedings

From time to time, the Registrant may be a party to certain legal actions and claims arising in the ordinary course of business. While the outcome of these events cannot be predicted with certainty, the Partnership does not expect these matters to have a material effect on its financial position or results of operations.

ITEM 5. Market for Registrant’s Common Equity, ~~and~~ Related Stockholder Matters and Issuer Purchases of Equity Securities

AtOn March 31, ~~2021~~2022, the Registrant had 14,600 outstanding limited partnership interests held of record by 1,901 subscribers. There is no established public or organized trading market for the partner interests.

~~Revenues~~Cash received from sales of oil and natural gas which, in the sole judgment of the managing general partner, are not required to meet the Registrant’s obligations will be distributed to the partners at least quarterly in accordance with the Registrant’s Partnership Agreement. Distributions made to partners and state tax payments for the benefit of investor partners during the years ended December 31, ~~2020~~2021 and ~~2019~~2020 were $~~573~~2,~~710~~825,800 and $2573,~~747~~710,~~426,~~ respectively. Since inception, the Partnership has made distributions of $7174,~~933~~759,~~513~~313, inclusive of state tax payments.

Not required under Regulation S-K, Item 301 for smaller reporting companies.

ITEM 7.

Management’s Discussion and Analysis of Financial Condition and Results of Operations

General

The Registrant was formed to engage primarily in the business of drilling development wells, to produce and market crude oil and natural gas produced from such properties, to distribute any net proceeds from operations to the general and limited partners and to the extent necessary, acquire leases which contain drilling prospects. The economic life of the Registrant depends on the period over which the Registrant’s oil and natural gas reserves are economically recoverable.

Current Price Environment

Oil, natural gas, and natural gas liquids prices are determined by many factors outside of the Partnership’s control. Historically, world-wide oil and natural gas prices and markets have been subject to significant change and may continue to be in the future. Global macroeconomic factors contributing to uncertainty ~~within~~ within the industry include real or perceived geopolitical risks in oil-producing regions of the world, particularly the Middle East; forecasted levels of global economic growth combined with forecasted global supply; supply levels of oil and natural gas due to ~~exploration~~ exploration and development activities in the United States; global health issues, such as the strain of coronavirus (“COVID-19”) ~~and~~ and the ~~development~~wide distribution of the vaccine tocounteracting ~~counteract~~ it; environmental and climate change regulation; actions taken by OPEC; and the ~~strength~~ strength of the U.S. dollar in international currency markets.

~~Results~~In recent months, the conflict between Russia and Ukraine has driven oil and natural gas prices up significantly, in part because of ~~Operations~~sanctions by the European Union, the United Kingdom and the U.S. on imports of oil and gas from Russia. Recent Russian actions have further contributed to global uncertainties for the future, causing even higher oil and natural gas prices.

~~Year~~However, ~~ended~~continuing ~~December~~political ~~31,~~and ~~2020~~social ~~compared~~ attention to the ~~year~~issue ~~ended~~of ~~December~~global 31climate change has resulted in both existing and pending national, regional, and local legislation and regulatory ~~2019:~~measures to limit or reduce emissions of so-called greenhouse gases, such as mandates for renewable energy.

	Year Ended December 31,
	2020		2019
Oil sales	$	1,120,360	$	2,027,438
Barrels produced		30,838		38,921
Average price/bbl	$	36.33	$	52.09
Gas sales	$	356,625	$	571,083
Mcf produced		227,410		272,577
Average price/mcf	$	1.57	$	2.10

The trend in oil and natural gas regulation has been to increase regulatory restrictions and limitations on such activities. Any changes in, or more stringent enforcement of, these laws and regulations may result in delays or restrictions in permitting or development of projects or more stringent or costly construction, drilling, water management or completion activities or waste handling, storage, transport, remediation, or disposal emission or discharge requirements which could have an adverse effect on the Partnership.

Oil and natural gas revenues. Oil and natural gas sales decreased by $1,121,536 a 43.2% decrease, for the year ended December 31, 2020 as compared to the year ended December 31, 2019.

Of this decrease, $613,419 and $143,627 were due to decreases in the average prices of oil and natural gas sold, respectively. The average price fell to $36.33 from $52.09 per barrel (bbl) of oil and to $1.57 from $2.10 per thousand cubic feet (mcf) of natural gas for the year ended December 31, 2020 as compared to the year ended December 31, 2019.

Also contributing to the decrease were $293,659 and $70,831 due to decreases in the volumes of oil and natural gas sold, respectively, by 8,083 bbls of oil and 45,167 mcf natural gas for the year ended December 31, 2020 as compared to the year ended December 31, 2019.

Lease operations. Lease operating expense during the year ended December 31, 2020 decreased to $744,694 from $898,637 for the year ended December 31, 2019 due to more well repairs and workovers.

Production taxes. Production taxes during the year ended December 31, 2020 decreased to $103,374 from $181,584 for the year ended December 31, 2019. This was due to lower overall oil and natural gas revenue for the year ended December 31, 2020.

Administrative and general expense. Administrative and general expense for the year ended December 31, 2020 fell to $144,430 from $162,301 for the year ended December 31, 2019. This was due to lower total administrative expenses allocable to the Partnership.

Depreciation, depletion and amortization. Depreciation, depletion and amortization for the year ended December 31, 2020 decreased to $239,322 from $281,478 for the year ended December 31, 2019. This was due to the overall decrease in oil and natural gas production.

Results of Operations

Year ended December 31, 2021 compared to the year ended December 31, 2020:

	Year Ended December 31,
	2021		2020
Oil sales	$	3,375,790	$	1,120,360
Barrels produced		50,685		30,838
Average price/bbl	$	66.60	$	36.33

Natural gas sales	$	1,680,047	$	356,625
Mcf produced		281,221		227,410
Average price/mcf	$	5.97	$	1.57

Oil and natural gas revenues. Oil and natural gas sales increased by $3,578,852 a 242.3% increase, for the year ended December 31, 2021 as compared to the year ended December 31, 2020.

Of this increase, $933,554 and $1,001,949 were due to increases in the average prices of oil and natural gas sold, respectively. The average price rose to $66.60 from $36.33 per barrel (bbl) of oil and to $5.97 from $1.57 per thousand cubic feet (mcf) of natural gas for the year ended December 31, 2021 as compared to the year ended December 31, 2020.

Also contributing to the increase were $1,321,876 and $321,473 due to increases in the volumes of oil and natural gas sold, respectively, by 19,847 bbls of oil and 53,811 mcf natural gas for the year ended December 31, 2021 as compared to the year ended December 31, 2020. Much of the increase in volumes was due to six wells which had been farmed out and which paid out during the year ended December 31, 2021.

Lease operations. Lease operating expense during the year ended December 31, 2021 increased to $835,448 from $744,694 for the year ended December 31, 2020 due to more well repairs and workovers.

Production taxes. Production taxes during the year ended December 31, 2021 increased to $388,508 from $103,374 for the year ended December 31, 2020. This was due to higher overall oil and natural gas revenue for the year ended December 31, 2021.

Administrative and general expense. Administrative and general expense for the year ended December 31, 2021 rose to $255,570 from $144,430 for the year ended December 31, 2020. This was due to higher total administrative expenses allocable to the Partnership .

Depreciation, depletion and amortization. Depreciation, depletion and amortization for the year ended December 31, 2021 decreased to $224,650 from $239,322 for the year ended December 31, 2020. This was due to a lower net full cost pool resulting from prior period depreciation, depletion and amortization deductions and cost ceiling write-downs.

Liquidity and Capital Resources

Cash increased by $11101,~~142~~557 during the year ended December 31, ~~2020~~2021. Cash ~~flows~~received from ~~operating~~sales ~~activities~~of oil and ~~proceeds~~natural ~~from~~gas ~~asset sales~~ were utilized primarily for cash distributions to partners. All wells for which funds have been committed have been drilled; the Partnership has no planned drilling activity in the future. Any incidental future capital expenditures incurred will be paid with current available cash and revenues generated through oil and natural gas sales. ~~Revenues~~Cash received from sales of oil and natural gas which, in the sole judgment of the managing general partner, are not required to meet the Registrant’s obligations will be distributed to the partners at least quarterly in accordance with the Registrant’s Partnership Agreement.

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of ~~assets~~ assets and liabilities and disclosure of contingent assets and liabilities aton the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Significant estimates inherent in the Registrant’s financial statements include the estimate of oil and natural gas reserves and future abandonment costs. Changes in oil and natural gas prices and the changes in production estimates could have a significant effect on reserve estimates. The reserve estimates directly impact the computation of depreciation, depletion, and amortization, asset retirement obligation, and the ceiling test for the Registrant’s oil and natural gas properties.

All financing activities of the Registrant are reported in the financial statements. The Registrant does not engage in any off-balance sheet financing arrangements. Additionally, the Registrant has no contractual obligations but has a financial obligation to plug and abandon non-producing properties as discussed below.

9 8

Full Cost Method of Accounting

The Partnership follows the full-cost method of accounting for its oil and natural gas activities. Under the full-cost method, all productive and non-productive costs incurred in the acquisition, exploration and development of oil and natural gas properties are capitalized. Depreciation, depletion and amortization of oil and natural gas properties subject to amortization is computed on the units-of-production method based on the proved reserves underlying the oil and natural gas properties. AtOn December 31, ~~2020~~2021 and ~~2019~~2020, all capitalized costs were subject to amortization. Proceeds from the sale or other disposition of properties are credited to the full cost pool. Gains and losses are not recognized unless such adjustments would significantly alter the relationship between capitalized costs and the proved oil and natural gas reserves. Capitalized costs are subject to a quarterly ceiling test that limits such costs to the aggregate of the present value of estimated future net cash flows of proved reserves, computed using the 12-month unweighted average of first- day- of the- month oil and natural gas prices, adjusted by a pricing differential associated with the particular property discounted at 10%, and the lower of cost or fair value of unproved properties. If unamortized costs capitalized exceed the ceiling, the excess is charged to expense in the period the excess occurs. There were no cost ceiling write-downs during the years ended December 31, ~~2020~~2021 and ~~2019~~ 2020.

Asset Retirement Obligations

The Partnership has recognized an estimated liability for future plugging and abandonment costs. A liability for the estimated fair value of the future plugging and abandonment costs is recorded ~~with~~ with a corresponding increase in the full cost pool at the time a new well is drilled. ~~Depreciation~~Depletion expense associated with estimated ~~plugging~~ plugging and abandonment costs is recognized in accordance with the full cost methodology.

The Partnership estimates a liability for plugging and abandonment costs based on historical experience and estimated well life. The liability is discounted using the credit-adjusted risk-free rate. Revisions to the liability could occur due to changes in well plugging and abandonment costs or well useful lives, or if federal or state regulators enact new well restoration requirements. The Partnership recognizes accretion expense in connection with the discounted liability over the remaining life of the well.

A reconciliation of the Partnership’s liability for well plugging and abandonment costs as of and for the years ended December 31, ~~2020~~2021 and ~~2019~~December 31, 2020 is as follows:

	2020			2019

Organization and Related Party Transactions

The Partnership was organized on February 9, 2010 in accordance with the laws of the state of Delaware. MD, a Delaware Corporation, has been appointed as the Registrant’s managing general partner. MD has no significant equity interest in the Registrant. MOC is operator of oil and natural gas properties owned by the Partnership. Mewbourne Holdings, Inc. is the parent of both MD and MOC. Substantially all transactions are with MD and MOC.

In the ordinary course of business, MOC will incur certain costs that will be passed on to well owners of the well for which the costs were incurred. The Partnership will ~~receive~~be ~~its~~allocated its portion of these costs based upon its ownership in each well incurring the costs. These costs are referred to as operator charges and are standard and customary in the oil and natural gas industry. Operator charges include recovery of natural gas marketing costs, fixed ~~rate~~ rate overhead, supervision, pumping, and equipment furnished by the operator, some of which will be included in the full cost pool ~~pursuant~~ pursuant to Rule 4-10(c)(2) of Regulation S-X. Amounts ~~accrued for and~~ paid to MOC for operator charges totaled $~~401~~426,~~246~~566 and $~~430~~401,~~646~~ 246 for the years ended December 31, ~~2020~~2021 and ~~2019~~2020, respectively. Operator charges are billed in accordance with the Program and Partnership Agreements.

In accordance with the Partnership agreement, during any particular calendar year, the total amount of administrative expenses allocated to the Partnership by MOC shall not exceed the greater of of (a) 3.5% of the Partnership’s gross revenue from the sale of oil and natural gas production during each year (calculated ~~without~~ without any deduction for operating costs or other costs and expenses) or (b) the sum of $50,000 plus 0.25% of the capital contributions of limited and general partners. Administrative expenses can only be paid out of funds available for distributions. Under this arrangement, $57176,~~788~~ 954 and $9457,~~489~~788 were allocated to the Partnership during the years ended December 31, ~~2020~~2021 and ~~2019~~2020, respectively.

	Partnership			MD (1)
Revenues:
Proceeds from disposition of depreciable and depletable properties		75	%		25	%
All other revenues		75	%		25	%

Costs and expenses:

(1)

As noted above, pursuant to the Program, MD must contribute 100% of organization and offering costs and lease acquisition costs which should approximate 15% of total capital costs. To the extent that organization and offering costs and lease acquisition costs are less than 15% of total capital costs, MD is responsible for tangible drilling costs until its share of the Program’s total capital costs reaches approximately 15%. The Partnership’s financial statements reflect its respective proportionate interest in the Program.

Controls and Procedures

(a) Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this report, MD’s management conducted an evaluation, under the supervision and with the participation of MD’s principal executive officer and principal financial officer, of the Registrant’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) ~~under~~ under the Exchange Act). Based on this evaluation, MD’'s principal executive officer and principal financial officer concluded that, as as of the end of the period covered by this report, the Registrant’s disclosure controls and procedures are effective. Notwithstanding the foregoing, a control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that it will detect or uncover failures within the Registrant to disclose material information otherwise required to be set forth in the Registrant’s periodic reports.

((b) ~~MD Management’s~~ Annual Report on Internal Control Over Financial Reporting

MD’s management, as managing general partner of the Partnership, is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f). Under the supervision and with the participation of MD’s management, including MD’s principal executive officer and principal financial officer, MD conducted an evaluation of the effectiveness of the Partnership’s internal control over financial reporting based on the framework in “Internal Control — Integrated Framework” (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on MD’s evaluation under the framework in “Internal Control — Integrated Framework”, MD’s management concluded that internal control over financial reporting was effective as of December 31, ~~2020~~2021. This annual report does not include an attestation report of the Registrant’s independent ~~registered~~ registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by the Registrant’s independent registered public accounting firm pursuant to rules of the SEC that permit the Registrant to provide only management’s report in this annual report. There have been no changes in MD’s internal controls for the quarter ended December 31, ~~2020~~2021 or in other factors which have materially affected or are reasonably likely to materially affect the internal controls over financial reporting.

WITH REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

As of and for the years ended December 31, ~~2020~~ 2021 and ~~2019~~2020

18 17

Report of Independent Registered Public Accounting Firm

~~To the~~ Partners of Mewbourne Energy Partners 10-A, L.P. and the Board of Directors of Mewbourne Development Corporation (MD)

Tyler, Texas

Opinion on the Financial Statements

We have audited the accompanying balance sheets of Mewbourne Energy Partners 10-A, L.P. (the “Partnership”) as of December 31, ~~2020~~2021 and ~~2019~~2020, the related statements of operations, changes in partners’ capital, and cash flows for the years then ended, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all ~~material~~ material respects, the financial position of the Partnership at December 31, ~~2020~~2021 and ~~2019~~2020, and the results of its operations and its ~~cash~~ cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Partnership’s management. Our responsibility is to express an opinion on the Partnership’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Partnership in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Partnership is not required to have, nor ~~were~~ were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of of the Partnership’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the ~~consolidated~~ financial statements that was communicated or required to be communicated to the ~~audit~~ audit committee and that: (1) ~~relate~~relates to accounts or disclosures that are material to the ~~consolidated~~ financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the ~~consolidated~~ financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing separate opinions on the critical audit matter or on the accounts or disclosures to which it relates.

Estimated Future Net Cash Flows of Proved Reserves

The Partnership’s oil and gas properties, net balance was $32,~~032~~821,~~321~~ 969 as of December 31, ~~2020~~2021, and depreciation, depletion, and amortization (“DD&A”) expense for the year ended December 31, ~~2020~~2021 was $~~239~~224,~~322~~650, both of which substantially related to proved oil and natural gas properties. As described in Note 2 to the financial statements, the Partnership follows the full-cost method of accounting for its oil and gas activities. Capitalized costs are subject to a quarterly ceiling test that limits such costs to the aggregate of the present value of estimated future net cash flows of proved reserves, computed using the 12-month unweighted average of first- day- of the- month oil and natural gas prices, ~~adjusted~~ adjusted by a pricing differential associated with the particular property, discounted at 10%, and the lower of cost or fair value of unproved properties. If unamortized costs capitalized exceed the ceiling, the excess is charged to expense in the period the excess occurs.

We identified the estimated future net cash flows of proved reserves as a critical audit matter. The principal consideration for our determination is that minor changes in the pricing ~~differentials~~ differentials applied to the 12-month first- day of- the- month historical averages could have a significant impact on the estimated future net cash flows of proved reserves. Auditing management’s judgment with respect to the pricing differentials involved a high degree of auditor judgment in the design of our audit procedures and the evaluation of the audit evidence obtained.

The primary procedures we performed to address this critical audit matter included:

•

Testing the completeness and accuracy of underlying data related to pricing differentials by obtaining the data utilized by Management and agreeing the data to general ledger activity.

•

Performing well-level differential testing by recalculating the differential for a sample of wells and comparing the recalculated differential to the well-level differential used in the estimated future net cash flows in the reserve report.

•

Evaluating evidence obtained in other areas of the audit and identifying whether contradictory evidence existed that would impact the pricing differentials.

We have served as the Partnership’'s auditor since 2010.

NOTES TO FINANCIAL STATEMENTS

1. Description of Business

Mewbourne Energy Partners 10-A, L.P., (the “Registrant” or the “Partnership”), a Delaware limited partnership engaged primarily in oil and natural gas development and production in Texas, Oklahoma, and New Mexico, was organized on February 9, 2010. The offering was part of a private placement pursuant to Section 4(2) of the Securities Act of 1933 and Regulation D promulgated thereunder. During 2012 all general partner equity interests were converted to limited partner equity interests. The managing general partner has no significant equity interest in the Partnership.

The Partnership’s sole business is the development and production of oil and natural gas. A substantial portion of the Partnership’s natural gas production is being sold regionally in the spot market. Due to the highly competitive nature of the spot market, prices are subject to seasonal and regional pricing fluctuations. In addition, such spot market sales are generally short-term in nature and are dependent upon obtaining transportation services provided by pipelines. The prices received for the Partnership’s oil and natural gas are subject to influences such as global consumption and supply trends.

2. Summary of Significant Accounting Policies

Full Cost Method of Accounting

The Partnership follows the full-cost method of accounting for its oil and natural gas activities. Under the full-cost method, all productive and non-productive costs incurred in the acquisition, exploration and development of oil and natural gas properties are capitalized. Depreciation, depletion and amortization of oil and natural gas properties subject to amortization is computed on the units-of-production method based on the proved reserves underlying the oil and natural gas properties. AtOn December 31, ~~2020~~2021 and ~~2019~~2020, all capitalized costs were subject to amortization. Proceeds from the sale or other disposition of properties are credited to the full cost pool. Gains and losses are not recognized unless such adjustments would significantly alter the relationship between capitalized costs and the proved oil and natural gas reserves. Capitalized costs are subject to a quarterly ceiling test that limits such costs to the aggregate of the present value of estimated future net cash flows of proved reserves, computed using the 12-month unweighted average of first- day- of the- month oil and natural gas prices, adjusted by a pricing differential associated with the particular property, discounted at 10%, ~~and~~ and the lower of cost or fair value of unproved properties. If unamortized costs capitalized exceed the ceiling, the excess is charged to expense in the period the excess occurs. There were no cost ceiling write-downs during the years ended December 31, ~~2020~~2021 and ~~2019~~ 2020.

25 24

Cash

The Partnership maintains all its cash in one financial institution. At various times throughout the year, the cash amount may be in excess of the amount insured by the Federal Deposit Insurance Corporation.

Fair Value of Financial Instruments

The fair value of financial instruments is determined at discrete points in time based on relevant market information. Such estimates involve uncertainties and cannot be determined with precision. The estimated fair value of cash, accounts receivable, affiliate and accounts payable, affiliate approximates their carrying value due to their short-term nature.

Asset Retirement Obligations

A reconciliation of the Partnership’s liability for well plugging and abandonment costs as of and for the years ended December 31, ~~2020~~2021 and ~~2019~~2020 is as follows:

Oil and Natural Gas Sales

The Partnership’s oil and condensate production is sold and revenue recognized at or near the Partnership’s wells under short-term purchase contracts at prevailing prices in accordance with arrangements which are customary in the oil industry. Sales of natural gas applicable to the Partnership’s interest are recorded as revenue when the natural gas is metered and title transferred pursuant to the natural gas sales contracts covering the Partnership’s interest in natural gas reserves.

26 25

Substantially all the Partnership’s accounts ~~receivable~~ receivable result from oil and natural gas sales by Mewbourne Oil Company (MOC) to third parties in the oil and natural gas industry. This concentration of customers may impact the Partnership’s overall credit risk in that these entities may be similarly affected by changes in economic and other conditions. Historically, the Partnership has not experienced significant credit losses on such receivables. No bad debt expense was recorded for the years ended December 31, ~~2020~~2021 or ~~2019~~2020. The Partnership cannot ensure that such losses will not occur in the future.

The Partnership has only non-operated working interests in oil and natural gas wells and receives monthly net revenue checks from the operator of these oil and natural gas wells. Each unit of oil and natural gas is accounted for as a separate performance obligation. It recognizes revenue for oil and condensate when control transfers to the purchaser at a contractually specified delivery point at or near the wellhead at market prices in accordance with the contractual arrangement. Sales of natural gas applicable to the Partnership’s interest are recorded as revenue when the natural gas is metered and control is transferred pursuant to the natural gas sales contracts covering the Partnership’s interest in natural gas reserves.

Disaggregation of Revenue

The Partnership has identified two material revenue streams in its business: oil sales and natural gas sales. Revenue attributable to each of the Partnership’s identified revenue streams is disaggregated in the Statements of Operations.

Principal versus ~~agent~~Agent

In the case of the non-operating agreements, the operator is responsible for providing the goods due to its contractual obligations with the purchaser. Based on the joint operating and marketing agreement arrangements between the Partnership and operator, the Partnership does not take title to the product prior to the operator’s ultimate sale to a customer. The operator is responsible for fulfilling promises to provide specified goods and remitting ~~proceeds~~ proceeds back to the Partnership for the Partnership’s proportionate share of the total product sold. ~~Mewbourne Oil Company (~~MOC), rather than the Partnership, is primarily responsible for fulfilling promises to provide specified goods. MOC, as the operator, enters into the sales contract with the third-party customers and directs all activities from the wellhead to the delivery point that make the commodity available to the customer; there is no agreement between the Partnership and the customers. In the event a production delay occurs because of, for example, well-equipment failure, MOC is responsible for correcting the issues preventing fulfillment of its promises to deliver product to its customers.

Accounts Receivable, affiliate

Under the Partnership’s joint operating and marketing agreements, the Partnership is entitled to consideration as production occurs at the wellhead and the value of such consideration is an estimate. Final amounts are only determined upon sale by the operator to the ultimate third-party customer, and recorded in “Accounts receivable, affiliate” in its balance ~~sheet~~sheets.

27 26

Income Taxes

The Partnership is treated as a partnership for income tax purposes and, as a result, income of the Partnership is reported on the tax returns of the partners and no recognition is given to income taxes in the financial statements.

The Partnership accounts for uncertainty in income taxes in accordance with applicable accounting guidance and recognizes the effects of those positions only if they are more likely than not of being sustained. As no liability had been recognized as of December 31, ~~2020~~2021 or ~~2019~~2020, the Partnership did not accrue for any interest or penalties.

Distributions

3. Organization and Related Party Transactions:

The Partnership was organized on February 9, 2010 in accordance with the laws of the state of Delaware. MOC is operator of oil and natural gas properties owned by the Partnership. Mewbourne Holdings, Inc. is the parent of both MD and MOC. Substantially all transactions are with MD and MOC.
