NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

1.       Organization and Summary of Significant Accounting Policies

Organization

The Ridgewood Energy A-1 Fund, LLC (the “Fund”), a Delaware limited liability company, was formed on February 3, 2009 and operates pursuant to a limited liability company agreement (the “LLC Agreement”) dated as of March 2, 2009 by and among Ridgewood Energy Corporation (the “Manager”) and the shareholders of the Fund, which addresses matters such as the authority and voting rights of the Manager and shareholders, capitalization, transferability of membership interests, participation in costs and revenues, distribution of assets and dissolution and winding up. The Fund was organized to primarily acquire interests in oil and gas properties located in the United States offshore waters of Texas, Louisiana and Alabama in the Gulf of Mexico.

The Manager has direct and exclusive control over the management of the Fund’s operations. The Manager performs, or arranges for the performance of, the management, advisory and administrative services required for the Fund’s operations. Such services include, without limitation, the administration of shareholder accounts, shareholder relations, the preparation, review and dissemination of tax and other financial information and the management of the Fund’s investments in projects. In addition, the Manager provides office space, equipment and facilities and other services necessary for the Fund’s operations. The Manager also engages and manages contractual relations with unaffiliated custodians, depositories, accountants, attorneys, corporate fiduciaries, insurers, banks and others as required. See Notes 2, 3 4 and 5.4.

Basis of Presentation

These unaudited interim condensed financial statements have been prepared by the Fund’s management in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and in the opinion of management, contain all adjustments (consisting of only normal recurring adjustments) necessary to present fairly the Fund’s financial position, results of operations and cash flows for the periods presented. Certain information and note disclosures normally included in annual financial statements prepared in accordance with GAAP have been omitted in these unaudited interim condensed financial statements. The results of operations, financial position, and cash flows for the periods presented herein are not necessarily indicative of future financial results. These unaudited interim condensed financial statements should be read in conjunction with the Fund’s December 31, 20172018 financial statements and notes thereto included in the Fund’s Annual Report on Form 10-K (“20172018 Annual Report”) filed with the Securities and Exchange Commission (“SEC”). The year-end condensed balance sheet data was derived from audited financial statements for the year ended December 31, 2017,2018, but does not include all annual disclosures required by GAAP.

Use of Estimates

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expense during the reporting period. On an ongoing basis, the Manager reviews its estimates, including those related to the fair value of financial instruments, depletion and amortization, determination of proved reserves, impairment of long-lived assets and asset retirement obligations. Actual results may differ from those estimates.

Summary of Significant Accounting Policies

The Fund has provided discussion of significant accounting policies in Note 1 of “Notes to Financial Statements” – “Organization and Summary of Significant Accounting Policies” contained in Item 8. “Financial Statements and Supplementary Data” within its 20172018 Annual Report. There have been no significant changes to the Fund’s significant accounting policies during the three and six months ended June 30, 2018, exceptMarch 31, 2019.

Fair Value Measurements

The Fund follows the accounting guidance for fair value measurement for measuring fair value of assets and liabilities in its financial statements. The Fund’s financial instruments consist of cash and cash equivalents, production receivable, due from affiliate, other current assets, salvage fund, due to operators, accrued expenses and long-term debt. Except for long-term debt, the carrying amounts of these instruments approximate fair value due to their short-term nature.

Mortgage-backed securities within the salvage fund are recorded based on Level 2 inputs, as noted belowsuch instruments trade in over-the-counter markets. The Fund’s long-term debt is valued using an income approach and classified as Level 3 in the fair value hierarchy. The fair value of long-term debt is estimated by discounting future cash payments of principal and interest to a present value amount using a market yield for revenue recognition. See Note 2. “Revenue Recognition” for discussiondebt instruments with similar terms, maturities and credit ratings. The Fund also applies the provisions of the Fund’s updatedfair value measurement accounting policies relatedguidance to revenue recognition for revenue from contracts with customers.its non-financial assets and liabilities, such as oil and gas properties and asset retirement obligations, on a non-recurring basis.

Salvage Fund

The Fund deposits cash in a separate interest-bearing account, or salvage fund, to provide for the dismantling and removal of production platforms and facilities and plugging and abandoning its wells at the end of their useful lives in accordance with applicable federal and state laws and regulations. As of June 30, 2018March 31, 2019 and December 31, 2017,2018, the Fund had investments in federal agency mortgage-backed securities as detailed in the following table, which are classified as available for sale.available-for-sale. Available-for-sale securities are carried in the financial statements at fair value. Mortgage-backed securities within the salvage fund are recorded based on Level 2 inputs, as such instruments trade in over-the-counter markets and the inputs are consistent with the Level 2 definition.

The unrealized gains on the Fund's investments in federal agency mortgage-backed securities were the result of fluctuations in market interest rates. The contractual cash flows of those investments are guaranteed by an agency of the U.S. government. Unrealized gains or losses on available-for-sale debt securities are reported in other comprehensive income until realized.

For all investments, interest income is accrued as earned and amortization of premium or discount, if any, is included in interest income. Interest earned on the account will become part of the salvage fund. There are no restrictions on withdrawals from the salvage fund.

Asset Retirement Obligations

For oil and gas properties, there are obligations to perform removal and remediation activities when the properties are retired. Upon the determination that a property is either proved or dry, a retirement obligation is incurred. The Fund recognizes the fair value of a liability for an asset retirement obligation in the period incurred. Plug and abandonment costs associated with unsuccessful projects are expensed as dry-hole costs. Annually, or more frequently if an event occurs that would dictate a change in assumptions or estimates underlying the obligations, the Fund reassesses its asset retirement obligations to determine whether any revisions to the obligations are necessary. The Fund maintains a salvage fund to provide for the funding of future asset retirement obligations.

Revenue Recognition

Oil and gas revenues are recognized at the point when control of oil and natural gas is transferred to the customers. Natural gas liquid sales are included within gas sales. The following table presents changesFund’s oil and natural gas generally is sold to its customers at prevailing market prices based on an index in asset retirementwhich the prices are published, adjusted for pricing differentials, quality of oil and pipeline allowances. Under the Fund’s oil and natural gas contracts, each unit of oil and natural gas represents a separate performance obligation; therefore, future volumes are wholly unsatisfied and the transaction price related to the remaining performance obligations foris the following periods:variable index-based price attributable to each unit of oil and natural gas that is transferred to the customer. The Fund invoices customers once its performance obligations have been satisfied, at which point the payment is unconditional. Accordingly, the Fund’s oil and natural gas contracts do not give rise to contract assets or liabilities. The receivables related to the Fund’s oil and gas revenue are included within “Production receivable” on the balance sheets.

Other revenue is generated from the Fund’s production handling, gathering and operating services agreement with an affiliated entity and other third parties. The Fund simply earns a fee for its services and recognizes these fees as revenue at the time its performance obligations are satisfied as the control of oil and natural gas is never transferred to the Fund, thus there are no unsatisfied performance obligations. The Fund’s project operator performs joint interest billing once the performance obligations have been satisfied, at which point the payment is unconditional. Accordingly, the Fund’s production handling, gathering and operating services agreement with an affiliated entity and other third parties does not give rise to contract assets or liabilities. The receivables related to the Fund’s proportionate share of revenue from an affiliate are included within “Due from affiliate” on the Fund’s balance sheets. The receivables related to the Fund’s proportionate share of revenue from third parties are presented as a reduction from “Due to operator” on the Fund’s balance sheets. The receivables are settled by issuance of a non-cash credit from the Beta Project operator to the Fund when the operator performs the joint interest billing of the lease operating expenses due from the Fund.

During

The Fund also has an estimation process for revenue and related accruals, and any identified difference between its revenue estimates and actual revenue have not been significant. For the six months ended June 30, 2017, the Fund recorded credits to depletion expense totaling $0.1 million related to an adjustment to the asset retirement obligation for a fully depleted property.period ending March 31, 2019 and 2018, revenue recognized from performance obligations satisfied in previous periods is not significant.

Impairment of Long-Lived Assets

The Fund reviews the carrying value of its oil and gas properties for impairment whenever events and circumstances indicate that the recorded carrying value of the assets may not be recoverable. Impairments are determined by comparing estimated future net undiscounted cash flows to the carrying value of the assets at the time of the review. If the carrying value exceeds the estimated future net undiscounted cash flows, the carrying value of the asset is written down to estimated fair value, which is determined using a valuation techniquetechniques that considersinclude both market and income approaches and usinguse Level 3 inputs. The fair value determinations require considerable judgment and are sensitive to change. Different pricing assumptions, reserve estimates or discount rates could result in a different calculated impairment.

There were no impairments of oil and gas properties during each of the three and six months ended June 30, 2018March 31, 2019 and 2017.2018. Fluctuations in oil and natural gas commodity prices may impact the fair value of the Fund’s oil and gas properties. If oil and natural gas commodity prices decline, even if only for a short period of time, it is possible that impairments of oil and gas properties will occur.

Recent Accounting Pronouncements

In May 2014,August 2018, the Financial Accounting Standards Board (“FASB”) issued accounting guidance on revenue recognition (“New Revenue Standard”),fair value measurement, which providesadds, among other things, disclosure requirements for a single five-step modelthe range and weighted average of significant unobservable inputs used to be applied to all revenue contracts with customers. In July 2015,develop Level 3 fair value measurements. This accounting guidance is effective for the FASB issued a deferral ofFund in the effective date of the New Revenue Standard to 2018,first quarter 2020 with early adoption permitted in 2017. permitted. The Fund does not expect this accounting guidance will have a material impact on its financial statements upon adoption.

In MarchFebruary 2016, the FASB issued accounting guidance which clarifies the implementation guidance on principal versus agent considerations in the New Revenue Standard. In April 2016, the FASB issued guidance on identifying performance obligations and licensing and in May 2016, the FASB issued final amendments which provided narrow scope improvements and practical expedients related to the implementation of the New Revenue Standard. The New Revenue Standard may be applied either retrospectively or through the use of a modified-retrospective method. Under the New Revenue Standard, the revenue associated with the Fund’s existing contracts will be recognized in the period that control of the related commodity is transferred to the customer, which is generally consistent with the Fund’s previous revenue recognition model. The Fund adopted the New Revenue Standard using the modified retrospective methodleases as amended on January 1, 2018. See Note 2. “Revenue Recognition” for the required disclosures related to the impact of adopting this guidance and a discussion of the Fund’s updated policies related to revenue recognition for revenue from contracts with customers.

2.       Revenue Recognition

The Fund adopted the New Revenue Standard on January 1, 2018 using the modified retrospective method for all new contracts entered into after January 1, 2018 and July 2018, which requires an entity to recognize all lease assets and liabilities with a term greater than one year on the balance sheet, disclose key quantitative and qualitative information about leasing arrangements, and permits an entity not to evaluate existing contracts for which revenues haveor expired land easements that were not been recognizedpreviously assessed under the previous revenue guidance as of December 31, 2017. Although the Fund did not identify changes to its revenue recognition that resulted in a cumulative adjustment to retained earnings on January 1, 2018, the adoption of theexisting lease guidance. The accounting guidance resulted in enhanced disclosures relateddoes not apply to revenue recognition policies, the Fund’s performance obligations and significant judgments used in applying the New Revenue Standard.

Revenue from Contracts with Customers

Oil and gas revenues are recognized at the point when controlleases of mineral rights to explore for or use of oil and natural gas is transferredgas. The accounting guidance was effective for the Fund beginning January 1, 2019. Although the Fund, as a non-operator, does not enter into lease agreements to support its operations, the customers. Natural gas liquid (“NGL”) sales are included within gas sales. The Fund’s oilFund completed its evaluation of existing contracts that may have a lease impact and natural gas generally is soldembedded lease features to its customers at prevailing market prices based on an index indetermine the contracts to which the prices are published, adjusted for pricing differentials, quality of the oil and pipeline allowances.

Oil and Gas Revenue

Generally,new guidance applies. Based on this evaluation, the Fund sells oildetermined its existing contracts did not meet the definition of leases under the new accounting guidance and natural gas under two types of agreements, which are common in the oil and gas industry. In the first type of agreement, or a netback agreement, the Fund receives a price, net of pricing differentials as well as transportation expense incurred by the customer, and the Fund records revenue at the wellhead at the net price received where control transfers to the customer. In the second type of agreement, the Fund delivers oil and natural gas to the customer at a contractually agreed-upon delivery point where the customer takes control. The Fund pays a third-party to transport the oil and natural gas and receives a specific market price from the customer net of pricing adjustments. The Fund records the transportation expense within operating expenses in the statements of operations.

Under the Fund’s natural gas processing contracts, the Fund delivers natural gas to a midstream processing company at the inlet of the midstream processing company’s facility. The midstream processing company gathers and processes the natural gas and remits the proceeds to the Fundtherefore, did not qualify for the sale of NGLs. In this type of arrangement, the Fund evaluates whether it is the principal or agent in the transaction. For those contracts where the Fund concluded that it is the principal and the ultimate third-party purchaser is the customer, the Fund recognizes revenue on a gross basis, with transportation, gathering and processing fees recorded as an expense within operating expenses in the statements of operations.

In certain instances, the Fund may elect to take its residue gas and NGLs in-kind at the tailgate of the midstream company’s processing plant and subsequently market such volumes. Through its marketing process, the Fund delivers the residue gas and NGLs to the ultimate third-party customer at a contractually agreed-upon delivery point and receives a specified market price from the customer. In this arrangement, the Fund recognizes revenue when control transfers to the customer at the delivery point based on the market price received from the customer. The transportation, gathering and processing fees are recorded as expense within operating expenses in the statements of operations.lease accounting.

The Fund assesses the performance obligations promised in its oil and natural gas contracts based on each unit of oil and natural gas that will be transferred to its customer because each unit is capable of being distinct. The Fund satisfies its performance obligation when control transfers at a point in time when its customer is able to direct the use of, and obtain substantially all of the benefits from, the oil and natural gas delivered. Under each of the Fund’s oil and natural gas contracts, contract prices are variable and based on an index in which the prices are published, which fluctuate as a result of related industry variables, adjusted for pricing differentials, quality of the oil and pipeline allowances. The use of index-based pricing with predictable differentials reduces the level of uncertainty related to oil and gas prices. Additionally, any variable consideration is not constrained. Payments are received in the month following the oil and natural gas production month. Adjustments that occur after delivery, such as quality bank adjustments, are reflected in revenue in the month payments are received.

Transaction price allocated to remaining performance obligations

Under the Fund’s oil and natural gas contracts, each unit of oil and natural gas represents a separate performance obligation, therefore, future volumes are wholly unsatisfied and the transaction price related to the remaining performance obligations is the variable index-based price attributable to each unit of oil and natural gas that is transferred to the customer.

Contract balances

The Fund invoices customers once its performance obligations have been satisfied, at which point the payment is unconditional. Accordingly, the Fund’s oil and natural gas contracts do not give rise to contract assets or liabilities under the New Revenue Standard. The receivables related to the Fund’s oil and gas revenue are included within “Production receivable” on the balance sheets.

Prior period performance obligations

The Fund records oil and gas revenue in the month production is delivered to its customers. However, settlement statements for residue gas and NGLs sales may not be received for 30 to 60 days after the date production is delivered. As a result, the Fund is required to estimate the amount of production delivered to the purchaser and the price that will be received for the sale of the residue gas and NGLs. The Fund records the differences between its estimates and the actual amounts received in the month that the payment is received from the customer. The Fund has an estimation process for revenue and related accruals, and any identified difference between its revenue estimates and actual revenue historically have not been significant. There was no material revenue recognized in the current period from performance obligations satisfied in previous periods.

Pursuant to the terms of the LLC Agreement, the Manager is entitled to receive an annual management fee, payable monthly, of 2.5% of total capital contributions, net of cumulative dry-hole and related well costs incurred by the Fund, however, the Manager is permitted to waive the management fee at its own discretion. Therefore, the management fee may be temporarily waived to accommodate the Fund’s short-term commitments. Management fees during each of the three and six months ended June 30,March 31, 2019 and 2018 and 2017 were $0.1 million and $0.2 million, respectively.million.

The Manager is also entitled to receive 15% of the cash distributions from operations made by the Fund. Distributions paid to the Manager during the three months ended March 31, 2019 were $0.1 million. The Fund did not pay distributions during the three and six months ended June 30, 2018 and 2017.March 31, 2018.

The Fund utilizes Beta Sales and Transport, LLC, a wholly-owned subsidiary of the Manager, to facilitate the transportation and sale of oil and natural gas produced from the Beta Project.

During 2016, the Fund and other third-party working interest owners in the Beta Project entered into a production handling, gathering and operating services agreement (“PHA”) with Ridgewood Claiborne, LLC, a wholly-owned entity of Ridgewood Energy Oil & Gas Fund II, L.P. (“Institutional Fund II”), and other third-party working interest owners in the Claiborne Project. Institutional Fund II is an entity that is managed by the Fund’s Manager. During the three months ended March 31, 2019, the Fund earned $15 thousand representing its proportionate share of the production handling fees earned from Institutional Fund II, which is included within “Other revenue” on the Fund’s statements of operations. There were no such amounts recorded during the three months ended March 31, 2018. As of March 31, 2019 and December 31, 2018, the Fund’s receivables of $15 thousand and $0.1 million related to the Fund’s proportionate share of revenue from Institutional Fund II are included within “Due from affiliate” on the Fund’s balance sheets. The receivables are settled by issuance of a non-cash credit from the Beta Project operator to the Fund on behalf of the Claiborne Project working interest owners when the operator performs the joint interest billing of the lease operating expenses due from the Fund. The revenue received from the PHA will be utilized by the Fund to repay a portion of the long-term debt outstanding under its credit agreement until the loan is repaid in full, in no event later than December 31, 2022.

At times, short-term payables and receivables, which do not bear interest, arise from transactions with affiliates in the ordinary course of business.

The Fund has working interest ownership in certain oil and natural gas projects, which are also owned by other entities that are likewise managed by the Manager.

OnAs of March 31, 2019 and December 31, 2018, the Fund had outstanding borrowings of $3.0 million and $3.2 million, respectively, under its credit agreement dated November 27, 2012, as amended on September 30, 2016, September 15, 2017, June 1, 2018 the Fund and other participating funds managed by the Manager, Rahr Energy Investments LLC, as administrative agent and lender (and other lenders that may become a party thereto, collectively “Lenders”), entered into a third amendmentAugust 10, 2018 (the “Third Amendment”), effective as of September 1, 2018 (“Third Amendment Effective Date”), to the certain credit agreement, dated as of November 27, 2012 (as amended by the first amendment to credit agreement, dated September 30, 2016, and the second amendment to credit agreement and reaffirmation of waiver, dated September 15, 2017, the “Existing Credit Agreement”, and as amended by the Third Amendment, the “Credit Agreement”). As of March 31, 2019, the estimated fair value of the debt was $3.0 million.

The Fund reviewed the terms of the Third Amendment and determined that the conditions have been met, pursuant to Accounting Standard Codification 470-50Debt: Modification and Extinguishments (“ASC 470-50”) guidance, to treat the Third Amendment as a debt modification in a non-troubled debt restructuring. Pursuant to ASC 470-50 guidance, debt modifications are accounted for prospectively, new fees paid to the creditor and unamortized debt discounts and deferred financing costs are capitalized and amortized over the term of the amended debt and any third party fees that are directly related to the modification of the debt are expensed as incurred.

As of June 30, 2018 and December 31, 2017,April 1, 2019, the Fund had borrowings of $6.7 million and $7.2 million, respectively, under the Existing Credit Agreement.Fixed Reassessment Percentage was determined to be 30%.

Interest costs incurred during each of the six months ended June 30, 2018 and 2017 of $0.3 million were expensed and included on the statements of operations within “Interest expense, net”.

As additional consideration to the Lenders, the Fund has agreed to convey an overriding royalty interest (“ORRI”) in its working interest in the Beta Project to the Lenders. The Third Amendment fixes the Fund’s ORRI assigned to the Lenders at 10.81%. Such ORRI will not become payable to the Lenders until January 1, 2023. The Existing Credit Agreement contains customary covenants, with which the Fund was in compliance as of June 30, 2018March 31, 2019 and December 31, 2017.2018.

5.        Commitments and Contingencies

Capital Commitments

As of June 30, 2018,March 31, 2019, the Fund’s estimated capital commitments related to its oil and gas properties were $3.7$2.8 million (which include asset retirement obligations for the Fund’s projects of $2.1$1.9 million), of which $1.8$0.1 million is expected to be spent during the next twelve months. Additionally, current liabilities exceed current assets as of June 30, 2018. Future results of operations and cash flows are dependent on the continued successful development and the related production of oil and gas revenues from the Beta Project.

Based upon its current cash position and its current reserve estimates, the Fund expects cash flow from operations to be sufficient to cover its commitments, borrowing repayments and ongoing operations. Reserve estimates are projections based on engineering data that cannot be measured with precision, require substantial judgment, and are subject to frequent revision. However, if cash flow from operations is not sufficient to meet the Fund’s commitments, the Manager will temporarily waive all or a portion of the management fee as well as provide short-term financing to accommodate the Fund’s short-term commitments if needed.

Environmental and Governmental Regulations

Many aspects of the oil and gas industry are subject to federal, state and local environmental laws and regulations. The Manager and operators of the Fund’s properties are continually taking action they believe appropriate to satisfy applicable federal, state and local environmental regulations. However, due to the significant public and governmental interest in environmental matters related to those activities, the Manager cannot predict the effects of possible future legislation, rule changes, or governmental or private claims. As of June 30, 2018March 31, 2019 and December 31, 2017,2018, there were no known environmental contingencies that required adjustment to, or disclosure in, the Fund’s financial statements.

Oil and gas industry legislation and administrative regulations are periodically changed for a variety of political, economic, and other reasons. Any such future laws and regulations could result in increased compliance costs or additional operating restrictions, which could have a material adverse effect on the Fund’s operating results and cash flows. It is not possible at this time to predict whether such legislation or regulation, if proposed, will be adopted as initially written, if at all, or how legislation or new regulation that may be adopted would impact the Fund’s business.

BOEM Notice to Lessees on Supplemental Bonding

On July 14, 2016, the Bureau of Ocean Energy Management (“BOEM”) issued a Notice to Lessees (“NTL”) that discontinued and materially replaced existing policies and procedures regarding financial security (i.e. supplemental bonding) for decommissioning obligations of lessees of federal oil and gas leases and owners of pipeline rights-of-way, rights-of use and easements on the Outer Continental Shelf (“Lessees”).  Generally, the new NTL (i) ended the practice of excusing Lessees from providing such additional security where co-lessees had sufficient financial strength to meet such decommissioning obligations, (ii) established new criteria for determining financial strength and additional security requirements of such Lessees, (iii) provided acceptable forms of such additional security and (iv) replaced the waiver system with one of self-insurance. The new rule became effective as of September 12, 2016; however on January 6, 2017, the BOEM announced that it was suspending the implementation timeline for six months in certain circumstances. On June 22, 2017, the BOEM announced that the implementation timeline extension will remain in effect pending the completion of its review of the new NTL. The Fund, as well as other industry participants, are working withAs of March 31, 2019, the BOEM has not completed its operators and working interest partners to determine and agree uponreview nor has the correct level of decommissioning obligations to which they may be liable and the manner in which such obligations will be secured.NTL been enforced.  The impact of the NTL, if enforced without change or amendment, may require the Fund to fully secure all of its potential abandonment liabilities to the BOEM’s satisfaction using one or more of the enumerated methods for doing so.  Potentially this could increase costs to the Fund if the Fund is required to obtain additional supplemental bonding, fund escrow accounts or obtain letters of credit.

Insurance Coverage

The Fund is subject to all risks inherent in the oil and natural gas business. Insurance coverage as is customary for entities engaged in similar operations is maintained, but losses may occur from uninsurable risks or amounts in excess of existing insurance coverage. The occurrence of an event that is not insured or not fully insured could have a material adverse impact upon earnings and financial position. Moreover, insurance is obtained as a package covering all of the entities managed by the Manager. Depending on the extent, nature and payment of claims made by the Fund or other entities managed by the Manager, yearly insurance coverage may be exhausted and become insufficient to cover a claim by the Fund in a given year.

6.        Subsequent Events

On August 10, 2018, the Fund entered into a purchase and sale agreement (“PSA”) to sell a portion of the Fund’s working interest in the Beta Project to Walter Oil & Gas Corporation and Gordy Oil Company (collectively the “Buyers”) with an effective date of January 1, 2018. Certain other funds managed by the Manager were also parties to the PSA. The Fund has a 2.0% working interest in the Beta Project and sold a 0.364% working interest to the Buyers for a total purchase price of $3.3 million in cash, subject to purchase price and customary post-closing adjustments. The transaction closed on August 10, 2018 and the Fund received $3.1 million in cash, which included preliminary purchase price adjustments primarily related to the net cash flows from the effective date to the closing date.

The net carrying value of the working interest sold as of the closing date was approximately $2.2 million and the related asset retirement obligation was approximately $40 thousand. A gain to the Fund of approximately $0.9 million will be recognized in third quarter 2018, subject to customary post-closing adjustments. The proceeds from the sale are required to be utilized to repay a portion of the Existing Credit Agreement.

In conjunction with the sale and the repayment of the existing agreement, on August 10, 2018, the Fund and other participating funds managed by the Manager, entered into a fourth amendment (the “Fourth Amendment”) effective as of September 1, 2018 (“Fourth Amendment Effective Date”), to the Credit Agreement. The Fourth Amendment principally reduces the schedule of fixed percentage depending on the Fund’s ratio of outstanding debt to working interest ownership, which is the basis for the calculation of the monthly payment amount, and amends the interest calculation. The Fund is currently evaluating the impact of the Fourth Amendment on its financial statements.

Overview of the Fund’s Business

The Fund was organized primarily to acquire interests in oil and natural gas properties located in the United States offshore waters of Texas, Louisiana and Alabama in the Gulf of Mexico. The Fund’s primary investment objective is to generate cash flow for distribution to its shareholders by generating returns across a portfolio of oil and natural gas projects. Distributions to shareholders are made in accordance with the Fund’s limited liability company agreement (the “LLC Agreement”).

Ridgewood Energy Corporation (the “Manager”) is the Manager, and as such, has direct and exclusive control over the management of the Fund’s operations. The Manager performs, or arranges for the performance of, the management, advisory and administrative services required for the Fund’s operations. As compensation for its services, the Manager is entitled to an annual management fee, payable monthly, equal to 2.5% of the total capital contributions made by the Fund’s shareholders, net of cumulative dry-hole and related well costs incurred by the Fund. The Fund does not currently, nor is there any plan to, operate any project in which the Fund participates. The Manager enters into operating agreements with third-party operators for the management of all exploration, development and producing operations, as appropriate. The Manager also participates in distributions.

Subsequent Events

On August 10, 2018, the Fund entered into a purchase and sale agreement (“PSA”) to sell a portion of the Fund’s working interest in the Beta Project to Walter Oil & Gas Corporation and Gordy Oil Company (collectively the “Buyers”) with an effective date of January 1, 2018. Certain other funds managed by the Manager were also parties to the PSA. The Fund has a 2.0% working interest in the Beta Project and sold a 0.364% working interest to the Buyers for a total purchase price of $3.3 million in cash, subject to purchase price and customary post-closing adjustments. The transaction closed on August 10, 2018 and the Fund received $3.1 million in cash, which included preliminary purchase price adjustments primarily related to the net cash flows from the effective date to the closing date.

The net carrying value of the working interest sold as of the closing date was approximately $2.2 million and the related asset retirement obligation was approximately $40 thousand. A gain to the Fund of approximately $0.9 million will be recognized in third quarter 2018, subject to customary post-closing adjustments. The proceeds from the sale are required to be utilized to repay a portion of the existing credit agreement.

In conjunction with the sale and repayment of the existing agreement, on August 10, 2018, the Fund and other participating funds managed by the Manager, entered into a fourth amendment (the “Fourth Amendment”) effective as of September 1, 2018 (“Fourth Amendment Effective Date”), to the credit agreement. The Fourth Amendment principally reduces the schedule of fixed percentage depending on the Fund’s ratio of outstanding debt to working interest ownership, which is the basis for the calculation of the monthly payment amount, and amends the interest calculation. The Fund is currently evaluating the impact of the Fourth Amendment on its financial statements.

Commodity Price Changes

Changes in oil and natural gas commodity prices may significantly affect liquidity and expected operating results. Declines in oil and natural gas commodity prices not only reduce revenues and profits but could also reduce the quantities of reserves that are commercially recoverable and result in non-cash charges to earnings due to impairment.

Oil and natural gas commodity prices have been subject to significant fluctuations during the past several years. The Fund anticipates price cyclicality in its planning and believes it is well positioned to withstand price volatility. Despite operating in a volatile oil and natural gas commodity price environment, the Fund continued to advance the development of the Beta Project, which commenced production in 2016. The Fund has suspended distributionswill continue to closely manage and continues to conservecoordinate its capital spending estimates within its expected cash flows to provide for the continuedfuture development costs of the Beta Project.its producing projects, as budgeted. See “Results of Operations” under this Item 2. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this Quarterly Report for more information on the average oil and natural gas prices received by the Fund during the three and six months ended June 30,March 31, 2019 and 2018 and 2017 and the effect of such average prices on the Fund’s results of operations. If oil and natural gas commodity prices decline, even if only for a short period of time, the Fund’s results of operations and liquidity will be adversely impacted.

Market pricing for oil and natural gas is volatile and is likely to continue to be volatile in the future. This volatility is caused by numerous factors and market conditions that the Fund cannot control or influence. Therefore, it is impossible to predict the future price of oil and natural gas with any certainty. Factors affecting market pricing for oil and natural gas include:
