NOTES TO CONDENSED FINANCIAL STATEMENTS

(Unaudited)

1. Description of Business

Mewbourne Energy Partners 05-A, L.P. (the “Registrant” or the “Partnership”), a Delaware limited partnership, is engaged primarily in oil and gas development and production in Texas, Oklahoma, and New Mexico, and was organized on February 14, 2005. The offering of limited and general partnership interests began June 1, 2005 as a part of an offering registered under the name Mewbourne Energy Partners 04-05 Drilling Program, (the “Program”), and concluded July 29, 2005, with total investor contributions of $30,000,000 originally being sold to 1,128 subscribers of which $26,844,000 were sold to 998 subscribers as general partner interests and $3,156,000 were sold to 130 subscribers as limited partner interests. During 2007, all general partner equity interests were converted to limited partner equity interests. In accordance with the laws of the State of Delaware, Mewbourne Development Corporation (“MD”), a Delaware Corporation, has been appointed as the Partnership’s managing general partner. MD has no significant equity interest in the Partnership.

2. Summary of Significant Accounting Policies

Reference is hereby made to the Registrant’s Annual Report on Form 10-K for 2017, which contains a summary of significant accounting policies followed by the Partnership in the preparation of its financial statements. These policies are also followed in preparing the quarterly report included herein.

In the opinion of management, the accompanying unaudited financial statements contain all adjustments of a normal recurring nature necessary to present fairly our financial position, results of operations, cash flows and partners’ capital for the periods presented. The results of operations for the interim periods are not necessarily indicative of the final results expected for the full year. In preparing these financial statements, the Partnership has evaluated subsequent events for potential recognition and disclosure through the date the financial statements were issued.

Revenue Recognition

In 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 only non-operated working interests in oil and gas wells and receives monthly net revenue checks from the operator of these oil and gas wells. 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 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 control is transferred pursuant to the gas sales contracts covering the Partnership’s interest in gas reserves.

The Partnership has reviewed its partnership, joint operating and marketing agreements as they relate to its non-operated working interests and this ASU, which includes provisions regarding revenues and expenses under a gross-versus-net presentation as it relates to principal vs agent relationship, and has evaluated the impact on the presentation of its revenues and expenses under this gross-versus-net presentation guidance. Based on its review of how information about revenue has been presented for other purposes, including disclosures presented outside the financial statements and information used by management for evaluating performance operations, the appropriate categories for the disaggregation of revenue are oil and gas sales, as presented in the Partnership’s financial statements and related disclosures.

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 Condensed Statements of Operations.

Significant Judgments

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. 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 as a result 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.

New 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.

3. Accounting for Oil and Gas Producing Activities

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 ~~June~~September 30, 2018 and 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 natural 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 no cost ceiling write-downs for the ~~six~~nine months ended ~~June~~September 30, 2018 or 2017.

4. Asset Retirement Obligations

The Partnership has recognized an estimated asset retirement obligation liability (“ARO”) 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. Depletion 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 ~~six~~nine months ended ~~June~~September 30, 2018 and the year ended December 31, 2017 is as follows:

	2018		2017
Balance, beginning of period	$	269,035	$	256,573
Liabilities incurred		407		4,019
Liabilities reduced due to settlements and trades		—		(7,350	)
Liabilities reduced due to trades		—		(7,350	)
Accretion expense		812,~~448~~672		15,793
Balance, end of period	$	~~277~~282,~~890~~114	$	269,035

5. Related Party Transactions

In accordance with the laws of the State of Delaware, MD has been appointed as the Partnership’s managing general partner. MD has no significant equity interest in the Partnership. 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 the ordinary course of business, MOC will incur certain costs that will be passed on to 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. Services and operator charges are billed in accordance with the program and partnership agreements.

In accordance with the Partnership agreement, during any 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 natural 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.

The Partnership participates in oil and gas activities through the Program. The Partnership and MD are the parties to the Program, and the costs and revenues are allocated between them 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.

Item 2.

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

Liquidity and Capital Resources

Mewbourne Energy Partners 05-A, L.P. was formed February 14, 2005. The offering of limited and general partnership interests began June 1, 2005 and concluded July 29, 2005, with total investor contributions of $30,000,000. During 2007, all general partner equity interests were converted to limited partner equity interests.

Future capital requirements and operations will be conducted with available funds generated from oil and gas activities. No bank borrowing is anticipated. The Partnership had net working capital of $~~116~~121,~~771~~460 at ~~June~~September 30, 2018.

During the ~~six~~nine months ended ~~June~~ September 30, 2018, the Partnership made cash distributions to the investor partners (including state tax payments for the benefit of investor partners) in the amount of $~~324~~474,~~080~~090 as compared to $~~155~~330,~~142~~147 for the ~~six~~nine months ended ~~June~~September 330, 2017. Since inception, the Partnership has made distributions of $30,~~447~~597,~~566~~576, inclusive of state tax payments.

The sale of crude oil and natural gas produced by the Partnership will be affected by a number of factors that are beyond the Partnership’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 Partnership.

Results of Operations

For the three months ended ~~June~~ September 30, 2018 as compared to the three months ended ~~June~~September 30, 2017:

	Three Months Ended June 30,
	Three Months Ended September 30,
	2018		2017
Oil sales	$	~~131~~140,~~228~~908	$	97105,~~101~~061

Average price/mcf	$	2.4663	$	2.7953

Oil and gas revenues. As shown in the above table, total oil and gas sales ~~decreased~~rose by $5214,~~967~~400, ana 185.15% ~~decline~~increase, for the three months ended ~~June~~September 30, 2018 as compared to the three months ended ~~June~~September 30, 2017.

Of this ~~decrease~~increase, $1435,~~559~~038 and $636,~~737~~ 238 were due to ~~declines~~increases in the ~~volumes~~average prices of oil and gas sold, respectively. The ~~volumes~~average ofprices ~~oil~~rose ~~and~~to ~~gas~~$57.77 ~~sold~~from ~~fell~~$43.32 byper barrel ~~218 barrels~~ (~~bbls~~bbl) and byto ~~25,893~~$2.63 from $2.53 per thousand cubic feet (mcf) for the three months ended ~~June~~September 30, 2018 as compared to the three months ended ~~June~~September 30, 2017.

Item 3.

Quantitative and Qualitative Disclosures about Market Risk

1. Interest Rate Risk

The Partnership Agreement allows borrowings from banks or other financial sources of up to 20% of the total capital contributions to the Partnership without investor approval. Should the Partnership elect to borrow monies for additional development activity on Partnership properties, it will be subject to the interest rate risk inherent in borrowing activities. Changes in interest rates could significantly affect the Partnership’s results of operations and the amount of net cash flow available for partner distributions. Also, to the extent that changes in interest rates affect general economic conditions, the Partnership will be affected by such changes.

2. Commodity Price Risk

The Partnership does not expect to engage in commodity futures trading or hedging activities or enter into derivative financial instrument transactions for trading or other speculative purposes. The Partnership currently expects to sell a significant amount of its production from successful oil and gas wells on a month-to-month basis at market prices. Accordingly, the Partnership is at risk for the volatility in commodity prices inherent in the oil and gas industry, and the level of commodity prices will have a significant impact on the Partnership’s results of operations. For the ~~six~~nine months ended ~~June~~September 30, 2018, a 10% change in the price received for oil and gas production would have had an approximate $6088,000 impact on revenue.

3. Exchange Rate Risk

The Partnership currently has no income from foreign sources or operations in foreign countries that would subject it to currency exchange rate risk. The Partnership does not currently expect to purchase any prospects located outside of either the United States or United States coastal waters in the Gulf of Mexico.

Item 4.
