PART I

ITEM 1.

Business

Mewbourne Energy Partners 08-A, L.P. (the “Registrant” or the “Partnership”) is a limited partnership organized under the laws of the State of Delaware on March 7, 2008 (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, with a maximum offering amount of $73,000,000 (14,600 interests). On August 4, 2008, the offering of limited and general partnership interests in the Registrant was closed, with interests aggregating $73,000,000 originally being sold to accredited investors of which $68,105,000 were sold to accredited investors as general partner interests and $4,895,000 were sold to accredited investors as limited partner interests. During 2010 all general partner equity interests were converted to limited partner equity interests.

The Partnership participates in oil and 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 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 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 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 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. Gas will be sold to gas marketers and end users on the spot market. The spot market reflects immediate sales of gas without long-term contractual commitments. The future market condition for gas cannot be predicted with any certainty, and the Registrant may experience delays in marketing gas production and fluctuations in 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 gas exploration, development and production industry as a whole. Federal and state regulation of oil and 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. At April 21, ~~2018~~2019, MOC employed ~~422~~452 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 gas is not considered subject to seasonal factors although the price received by the Registrant for gas sales will generally tend to increase during the winter months. Order backlog is not pertinent to the Registrant’s business.

ITEM 1A.

Risk Factors

Oil and gas prices are volatile. Revenues, operating results, and profitability depend primarily upon the prices received for oil and gas sales. Prices also affect the amount of cash flow available for distribution. If prices were to decrease in the future, this could result in future write-downs of asset carrying values.

Historically, the markets for oil and gas have been volatile and they are likely to continue to be volatile. Wide fluctuations in oil and gas prices may result from relatively minor changes in the supply of and demand for oil and gas, market uncertainty and other factors that are beyond the Registrant’s control, including:

•

worldwide and domestic supplies of oil and gas;

•

weather conditions;

•

the level of consumer demand;

•

the price and availability of alternative fuels;

•

the proximity, accessibility and capacity of gas pipelines and other transportation facilities;

•

regional imbalances in supply and demand;

•

the price and level of foreign imports;

•

domestic and foreign governmental regulations and taxes;

•

the ability of the members of the Organization of Petroleum Exporting Countries to agree to and maintain oil price and production controls;

•

political instability or armed conflict in oil-producing regions; and

•

overall domestic and global economic conditions.

These factors and the volatility of the energy markets make it extremely difficult to predict future oil and gas price movements with any certainty. Declines in oil and gas prices would not only reduce revenue, but could reduce the amount of oil and gas that can be produced economically and, as a result, could have a material adverse effect on the Registrant’s financial condition, results of operations and reserves. For the year ended December 31, ~~2017~~2018, a 10% change in the price received for oil and gas production would have had an approximate $~~294~~270,000 impact on revenue.

The actual quantities and present value of proved reserves may prove to be lower than estimated.

This report contains estimates of proved reserves. These estimates are based upon various assumptions, including assumptions required by the Securities and Exchange Commission (“SEC”) relating to oil and gas prices, drilling and operating expenses, capital expenditures, taxes and availability of funds. The process of estimating oil and gas reserves is complex. The process involves significant decisions and assumptions in the evaluation of available geological, geophysical, engineering and economic data for each reservoir. Therefore, these estimates are inherently imprecise.

Actual future production, oil and gas prices, revenues, taxes, development expenditures, operating expenses and quantities of recoverable oil and gas reserves most likely will vary from these estimates. Such variations may be significant and could materially affect the estimated quantities and present value of proved reserves. In addition, the Registrant may adjust estimates of proved reserves to reflect production history, results of exploration and development drilling, prevailing oil and gas prices and other factors, many of which are beyond the Registrant’s control. The Registrant’s properties may also be susceptible to hydrocarbon drainage from production by operators on adjacent properties.

If prices were to decrease in the future, this could result in future write-downs of asset carrying values.

The Registrant utilizes the full-cost method of accounting for costs related to oil and gas properties. Under this method, all such costs (for both productive and nonproductive properties) are capitalized and amortized on an aggregate basis over the estimated lives of the properties using the unit-of-production method. However, these capitalized costs are subject to a ceiling test which limits such pooled costs to the aggregate of the present value of future net revenues attributable to proved oil and gas reserves discounted at 10% plus the lower of cost or market value of unproved properties. The full-cost ceiling is evaluated at the end of each quarter using the oil and gas pricing guidelines established by the SEC.

The Registrant’s ceiling test calculations ~~resulted~~indicated inno ~~cost~~impairment ~~ceiling~~of ~~write-downs~~oil ~~totaling~~and ~~$1,244,108~~gas properties during the ~~year~~years ended December 31, ~~2016.~~2018 ~~There~~and ~~were no cost ceiling write-downs for the year ended December 31,~~ 2017.

Oil and gas drilling and producing operations can be hazardous and may expose the Registrant to environmental liabilities.

Oil and gas operations are subject to many risks, including well blowouts, cratering and explosions, pipe failure, fires, formations with abnormal pressures, uncontrollable flows of oil, gas, brine or well fluids, and other environmental hazards and risks. If any of these risks occurs, the Registrant could sustain substantial losses as a result of:

•

injury or loss of life;

•

severe damage to or destruction of property, natural resources and equipment;

•

pollution or other environmental damage;

•

clean-up responsibilities;

•

regulatory investigations and administrative, civil and criminal penalties; and

•

injunctions resulting in limitation or suspension of operations.

There is inherent risk of incurring significant environmental costs and liabilities in exploration and production operations due to generation, handling, and disposal of materials, including wastes and petroleum hydrocarbons. The Registrant may incur joint and several, strict liability under applicable U.S. federal and state environmental laws in connection with releases of petroleum hydrocarbons and wastes on, under or from leased or owned properties, some of which have been used for oil and gas exploration and production activities for a number of years, often by third parties not under the Registrant’s control. While the Registrant maintains insurance against some, but not all, of the risks described above, the Registrant’s insurance may not be adequate to cover casualty losses or liabilities. Also, in the future the Registrant may not be able to obtain insurance at premium levels that justify its purchase.

In addition, in response to studies suggesting that emissions of certain gases may be contributing to warming of the earth’s atmosphere, many states are beginning to consider initiatives to track and record these gases, generally referred to as “greenhouse gases,” with several states having already adopted regulatory initiatives aimed at reducing emissions of greenhouse gases. Methane, a primary component of gas, and carbon dioxide, a byproduct of the burning of gas, are included among the types of gases targeted by greenhouse gas initiatives and laws. This movement is in its infancy but regulatory initiatives or legislation placing restrictions on emissions of methane or carbon dioxide that may be imposed in various states of the United States could adversely affect operations of oil and gas wells and the demand for oil and gas products.

ITEM 1B.

Unresolved Staff Comments

None.

ITEM 2.

Properties

Property Interests

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

Fractional working interests in developmental oil and 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 gas wells. At December 31, ~~2017~~2018, the Registrant owned working interests in ~~166~~163 producing wells. The Registrant had no drilling activity for the years ended December 31, ~~2017~~2018 and ~~2016~~2017. 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 by Forrest A. Garb & Associates, Inc. Their reserves estimate is filed with this report as Exhibit 99.1. The qualifications of William Donald Harris III, P.E., the technical person primarily responsible for overseeing his firm’s preparation of the Partnership’s reserve estimates are set forth below.

Over 25 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 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

At April 21, ~~2018~~2019, the Registrant had 14,600 outstanding limited partnership interests held of record by 1,848 subscribers. There is no established public or organized trading market for the partner interests.

Revenues 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, ~~2017~~2018 and ~~2016~~2017 were $1,~~643~~415,~~265~~448 and $1,~~125~~643,~~020~~265, respectively. Since inception, the Partnership has made distributions of $7071,~~089~~505,~~872~~319, inclusive of state tax payments.

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 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 gas reserves are economically recoverable.

All wells for which funds have been committed have been drilled. Any incidental future capital expenditures ~~incurred~~ incurred will be paid with current available cash and revenues generated through oil and gas sales. Revenues which, in the sole ~~judgment~~ judgment of the managing general partner, are not required to meet the Registrant’s obligations will be distributed to the ~~partners~~ partners at least quarterly in accordance with the Registrant’s Partnership Agreement.

Critical Accounting Policies

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 and liabilities and disclosure of contingent assets and liabilities at 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 gas reserves and future abandonment costs. Changes in oil and 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 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.

Recent Accounting Developments

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, a comprehensive new revenue recognition standard that will supersede nearly all existing revenue recognition guidance. The standard outlines a single comprehensive model for revenue recognition based on the core principle that an entity will recognize revenue when promised goods or services are transferred to clients, in an amount that reflects the consideration to which an entity expects to be entitled in exchange for those goods or services.

We have evaluated the impact of the ASU on our accounting policies, internal controls, and financial statements and related disclosures. We have non-operated working interests in oil and gas wells only and receive monthly net revenue checks from the operator of the oil and gas wells in which we have working interests. We have reviewed our partnership, joint operating and marketing agreements as they relate to our non-operated working interests and this ASU. The ASU includes provisions regarding future revenues and expenses under a gross-versus-net presentation as it relates to principal vs agent relationship. We have evaluated the impact on the presentation of our future revenues and expenses under this gross-versus-net presentation guidance. Based upon our assessments, the ASU will not have any effect on the timing of revenue recognition or our financial position.

Full Cost Method of Accounting

The Registrant follows the full-cost method of accounting for its oil and gas activities. Under the full-cost method, all productive and non-productive costs incurred in the acquisition, exploration and development of oil and gas properties are capitalized. Depreciation, depletion and amortization of oil and gas properties subject to amortization is computed on the units-of-production method based on the proved reserves underlying the oil and gas properties. Oil and gas properties are subject to a quarterly ceiling test that limits such costs to the aggregate of the present value of future net cash flows of proved reserves and the lower of cost or fair value of unproved properties. The present value of future net cash flows has been prepared by using the oil and gas pricing guidelines established by the SEC, projected development and production costs and a 10 percent annual discount rate.

Recent Accounting Developments

In February 2016, the FASB issued ASU 2016-02, “Leases.” ASU 2016-02 requires the recognition of lease assets and lease liabilities by lessees for those leases currently classified as operating leases and makes certain changes to the way lease expenses are accounted for. This update is effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. This update should be applied using a modified retrospective approach, and early adoption is permitted. In January 2018, the FASB issued ASU 2018-01, which permits an entity to elect an optional transition practical expedient to not evaluate land easements that exist or expire before the Partnership’s adoption of Topic 842 and that were not previously accounted for as leases under Topic 840. The Partnership is currently evaluating the new guidance to determine the impact it will have on its financial statements.

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 a corresponding increase in the full cost pool at the time a new well is drilled. Depreciation expense associated with estimated 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 for the year ended December 31, ~~2017~~2018 and December 31, ~~2016~~2017 is as follows:

	2017			2016

The Partnership was organized on March 7, 2008 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 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 their portion of these costs based upon their ownership in each well incurring the costs. These costs are referred to as operator charges and are standard and customary in the oil and gas industry. Operator charges include recovery of gas marketing costs, fixed rate overhead, supervision, pumping, and equipment furnished by the operator, some of which will be included in the full cost pool pursuant to Rule 4-10(c)(2) of Regulation S-X. Amounts accrued for and paid to MOC for operator charges totaled $~~570~~579,~~858~~912 and $~~600~~570,~~445~~858 for the years ended December 31, ~~2017~~2018 and ~~2016~~2017, respectively. Operator charges are billed in accordance with the Program and Partnership Agreements.

10In 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 (a) 3.5% of the Partnership’s gross revenue from the sale of oil and gas production during each year (calculated without any deduction for operating costs or other costs and expenses) or (b) the sum of $50,000 plus .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, $100,620 and $101,280 were allocated to the Partnership during the years ended December 31, 2018 and 2017, respectively.

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 (a) 3.5% of the Partnership’s gross revenue from the sale of oil and gas production during each year (calculated without any deduction for operating costs or other costs and expenses) or (b) the sum of $50,000 plus .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, $101,280 and $86,023 were allocated to the Partnership during the years ended December 31, 2017 and 2016, respectively.

The Partnership participates in oil and gas activities through a Drilling Program Agreement (the “Program”). The Partnership and MD are parties to the Program Agreement. The costs and revenues of the Program are allocated to MD and the Partnership as follows:

	Partnership			MD (1)
Revenues:
Proceeds from disposition of depreciable and depletable properties		70	%		30	%
All other revenues		70	%		30	%

Costs and expenses:
Organization and offering costs (1)		0	%		100	%
Lease acquisition costs (1)		0	%		100	%
Tangible and intangible drilling costs (1)		100	%		0	%
Operating costs, reporting and legal expenses, general and
administrative expenses and all other costs		70	%		30	%

(1)

As noted above, pursuant to the Program, MD must contribute 100% of organization and offering costs and lease acquisition costs which should approximate 20% of total capital costs. To the extent that organization and offering costs and lease acquisition costs are less than 20% of total capital costs, MD is responsible for tangible drilling costs until its share of the Program’s total capital costs reaches approximately 20%. 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 the Exchange Act). Based on this evaluation, MD's principal executive officer and principal financial officer concluded that, 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 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” (~~1992~~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, ~~2017~~2018. This annual report does not include an attestation report of the Registrant’s independent 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, ~~2017~~2018 or in other factors which have materially affected, or are reasonably likely to materially affect the internal controls over financial reporting.

Opinion on the Financial Statements

We have audited the accompanying balance sheets of Mewbourne Energy Partners 08-A, L.P. (the “Partnership”) as of December 31, ~~2017~~2018 and ~~2016~~2017, 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 respects, the financial position of the ~~Company~~Partnership at December 31, ~~2017~~2018 and ~~2016~~2017, and ~~the~~ the results of their operations and their cash flows for the years then ended, in conformity with accounting principles ~~generally~~ generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the ~~Company~~Partnership’s management. Our responsibility is to express an opinion on the ~~Company~~ 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 ~~Company~~ 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 ~~Company~~Partnership is not required to have, nor 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 the ~~Company~~Partnership’s internal control over financial reporting. Accordingly, we express no ~~such~~ 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.

We have served as the ~~Company~~Partnership's auditor ~~since~~ since 2008.

Mewbourne Energy Partners 08-A, L.P., (the “Registrant” or the “Partnership”), a Delaware limited partnership engaged primarily in oil and gas development and production in Texas, Oklahoma, and New Mexico, was organized on March 7, 2008. The offering of limited and general partner interests began May 1, 2008 as a part of a private placement pursuant to Section 4(2) of the Securities Act of 1933 and Regulation D promulgated thereunder, and concluded August 4, 2008, with total investor contributions of $73,000,000 originally being sold to accredited investors of which $68,105,000 were sold to accredited investors as general partner interests and $4,895,000 were sold to accredited investors as limited partner interests. During 2010 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 gas. A substantial portion of the Partnership’s 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 gas are subject to influences such as global consumption and supply trends.

2. Summary of Significant Accounting Policies

Full Cost Accounting

The Partnership follows the full-cost method of accounting for its oil and gas activities. Under the full-cost method, all productive and non-productive costs incurred in the acquisition, exploration and development of oil and gas properties are capitalized. Depreciation, depletion and amortization of oil and gas properties subject to amortization is computed on the units-of-production method based on the proved reserves underlying the oil and gas properties. At December 31, ~~2017~~2018 and ~~2016~~2017 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 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 gas prices, 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 ~~cost ceiling write-downs totaling $1,244,108 during the year ended December 31, 2016. There were~~ no cost ceiling write-downs ~~for~~during the ~~year~~years ended December 31, 2018 and 2017.

Subsequent Events

The Partnership has evaluated events and transactions for potential recognition or disclosure through the date the financial statements were issued.

The Partnership is currently evaluating the new guidance to determine the impact it will have on its financial statements.

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 FASB has issued guidance on determining the estimated fair value for financial instruments. This disclosure states that 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 for the year ended December 31, 2018 and December 31, 2017 is as follows:

Oil and Gas Sales

The Partnership’s has only non-operated working interests in oil and ~~condensate production~~gas iswells ~~sold~~and receives monthly net revenue checks from the operator of these oil and gas wells. It recognizes revenue ~~recognized~~for atoil orand ~~near~~condensate when control transfers to the ~~Partnership’s~~purchaser ~~wells~~at ~~under~~a ~~short-term~~contractually ~~purchase~~specified ~~contracts~~delivery point at or near the wellhead at prevailing prices in accordance with arrangements which are customary in the oil and gas industry. Sales of gas applicable to the Partnership’s interest are recorded as revenue when the gas is metered and ~~title~~control ~~transferred~~is transferred pursuant to the gas sales contracts covering the Partnership’s interest in gas reserves. The Partnership uses the sales method to recognize oil and gas revenue whereby revenue is recognized for the amount of production taken regardless of the amount for which the Partnership is entitled based on its working interest ownership. As of December 31, 2017 and 2016, no material gas imbalances between the Partnership and other working interest owners existed.

Substantially all of the Partnership’s accounts receivable result from oil and gas sales to third parties in the oil and 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 in ~~2017~~2018 or ~~2016~~2017. The Partnership cannot ensure that such losses will not be realized in the future.

~~Income~~In ~~Taxes~~May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers”, a comprehensive new revenue recognition standard. The Partnership has used the modified retrospective transition method to apply the effects of adopting this ASU, effective January 1, 2018, and has evaluated the impact of the ASU on its accounting policies, internal controls, and financial statements and related disclosures.

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 Condensed Statements of Operations.

Principal versus 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 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.

Transaction price allocated to remaining performance obligations

For the Partnership’s product sales, the Partnership has utilized the practical expedient in ASC 606 that states that it is not required to disclose the transaction price allocated to remaining performance obligations if the variable consideration is allocated entirely to a wholly unsatisfied performance obligation. Under the operator’s sales contracts, each unit of product represents a separate performance obligation; therefore, future volumes are wholly unsatisfied and disclosure of the transaction price allocated to remaining performance obligations is not required.

Contract balances

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.

Based upon its assessments, the ASU has no effect on the timing of the Partnership’s revenue recognition or its financial position.

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’s financial reporting basis of its net assets exceeded the tax basis of its net assets by $5,431,560 and $5,695,981 at December 31, 2018 and 2017, respectively.

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, 2018 or 2017, the Partnership did not accrue for any interest or penalties.

Distributions

Revenues 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, 2018 and 2017 were $1,415,448 and $1,643,265, respectively. Since inception, the Partnership has made distributions of $71,505,319, inclusive of state tax payments.

3. Organization and Related Party Transactions:

The Partnership was organized on March 7, 2008 in accordance with the laws of the state of Delaware. 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. ~~Mewbourne Oil Company (~~MOC) is operator of oil and 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 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 (a) 3.5% of the Partnership’s gross revenue from the sale of oil and gas production during each year (calculated without any deduction for operating costs or other costs and expenses) or (b) the sum of $50,000 plus .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, $~~101~~100,~~280~~620 and $86101,~~023~~280 were allocated to the Partnership during the years ended December 31, ~~2017~~2018 and ~~2016~~2017, respectively.

	Partnership			MD (1)
Revenues:
Proceeds from disposition of depreciable and depletable properties		70	%		30	%
All other revenues		70	%		30	%

Costs and expenses:
Organization and offering costs (1)		0	%		100	%

Tangible and intangible drilling costs (1)		100	%		0	%
Operating costs, reporting and legal expenses, general and
administrative expenses and all other costs		70	%		30	%

(1)

As noted above, pursuant to the Program, MD must contribute 100% of organization and offering costs and lease acquisition costs which should approximate 20% of total capital costs. To the extent that organization and offering costs and lease acquisition costs are less than 20% of total capital costs, MD is responsible for tangible drilling costs until its share of the Program’s total capital costs reaches approximately 20%.The Partnership’s financial statements reflect its respective proportionate interest in the Program.
