Organization and Limited Liability Company Matters [Abstract]
Organization and Limited Liability Company Matters	1. Organization and Limited Liability Company matters: ATEL 15, LLC (the “Company” or the “Fund”) was formed under the laws of the state of California on March 4, 2011 for the purpose of raising capital and originating equipment financing transactions and acquiring equipment to engage in equipment leasing and sales activities. The Managing Member of the Company is ATEL Managing Member, LLC (the “Managing Member” or “Manager”), a Nevada limited liability company. The Managing Member is controlled by ATEL Financial Services (“AFS”), a wholly-owned subsidiary of ATEL Capital Group. The Fund may continue until terminated as provided in the ATEL 15, LLC Amended and Restated Limited Liability Company Operating Agreement dated October 28, 2011 (the ”Operating Agreement”). Contributions in the amount of $500 were received as of May 3, 2011, which represented the initial member’s capital investment. As a limited liability company, the liability of any individual member for the obligations of the Fund is limited to the extent of capital contributions to the Fund by the individual member. The Company conducted a public offering of 15,000,000 Limited Liability Company Units (“Units”), at a price of $10 per Unit. As of December 21, 2011, subscriptions for the minimum number of Units (120,000, representing $1.2 million), excluding subscriptions from Pennsylvania investors, had been received and the Fund requested subscription proceeds to be released from escrow. On that date, the Company commenced initial operations and continued in its development stage activities until transitioning to an operating enterprise during the first quarter of 2012. Pennsylvania subscriptions are subject to a separate escrow and are released to the Fund only when aggregate subscriptions for all investors equal to at least $7.5 million. Total contributions to the Fund exceeded $7.5 million on April 14, 2012, at which time a request was processed to release the Pennsylvania escrowed amounts. The offering was terminated on October 28, 2013. As of December 31, 2023, cumulative gross contributions, less rescissions and repurchases (net of distributions paid and allocated syndication costs, as applicable), totaling $65.9 million (inclusive of the $500 initial Member’s capital investment) have been received. As of the same date, 6,529,607 Units were issued and outstanding. The Company’s principal objectives are to invest in a diversified portfolio of investments that will (i) preserve, protect and return the Company’s invested capital; (ii) generate regular cash distributions to unitholders, with any balance remaining after required minimum distributions to be used to purchase additional investments during the Reinvestment Period (ending six Pursuant to the terms of the Operating Agreement, the Managing Member and/or its affiliates receives compensation for services rendered and reimbursements for costs incurred on behalf of the Company (See Note 6). The Company is required to maintain reasonable cash reserves for working capital, the repurchase of Units and contingencies. The repurchase of Units is solely at the discretion of the Managing Member.

Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of significant accounting policies: Basis of presentation: The accompanying balance sheets as of December 31, 2023 and 2022, and the related statements of income, changes in members’ capital, and cash flows for the years then ended, have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and the rules and regulations of the Securities and Exchange Commission. Certain prior year amounts may have been reclassified to conform to the current year presentation. These reclassifications had no significant effect on the reported financial position or results from operations. Footnote and tabular amounts are presented in thousands, except as to Units and per Unit data In preparing the accompanying financial statements, the Company has reviewed, as determined necessary by the Managing Member, events that have occurred after December 31, 2023, up until the issuance of the financial statements. No events were noted which would require disclosure in the footnotes to the financial statements. Cash and cash equivalents: Cash and cash equivalents include cash in banks and cash equivalent investments such as U.S. Treasury instruments with original and/or purchased maturities of ninety days or less. Use of Estimates: The preparation of the financial statements in conformity 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 at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from the estimates. Such estimates primarily relate to the determination of residual values at the end of the lease term and expected future cash flows used for impairment analysis purposes and for determination of the allowance for doubtful accounts on accounts receivable. Accounts receivable: Accounts receivable represent the amounts billed under operating lease which is currently due to the Company. Allowances for doubtful accounts are typically established based on historical charge off and collection experience and the collectability of specifically identified lessees, and invoiced amounts. Accounts receivable deemed uncollectible are generally charged off against the allowance on a specific identification basis. Recoveries of amounts that were previously written-off are recorded as other income in the period received. Credit risk: Financial instruments that potentially subject the Company to concentrations of credit risk include cash and cash equivalents, operating lease receivables and accounts receivable. The Company places the majority of its cash deposits in noninterest-bearing accounts with financial institutions that have no less than $10 billion in assets. Such deposits are insured up to $250 thousand. The remainder of the Funds’ cash is temporarily invested in U.S. Treasury denominated instruments. The concentration of such deposits and temporary cash investments is not deemed to create a significant risk to the Company. Accounts receivable represent amounts due from lessees in various industries, related to equipment on operating leases. Equipment on operating leases and related revenue recognition: Equipment subject to operating leases is stated at cost. Depreciation is being recognized on a straight-line method over the terms of the related leases to the equipment’s estimated residual values. Off-lease equipment is generally not subject to depreciation. The Company depreciates all lease assets, in accordance with guidelines consistent with Accounting Standards Codification (ASC) 360-10-35-3, over the periods of the lease terms contained in each asset’s respective lease contract to the estimated residual value at the end of the lease contract. All lease assets are purchased only concurrent with the execution of a lease commitment by the lessee. Thus, the original depreciation period corresponds with the term of the original lease. Once the term of an original lease contract is completed, the subject property is typically sold to the existing user, re-leased to the existing user, or, when off-lease, is held for sale. Assets which are re-leased continue to be depreciated using the terms of the new lease agreements and the estimated residual values at the end of the new lease terms, adjusted downward as necessary. Assets classified as held-for-sale are carried at the lower of carrying amount, or the fair value less cost to sell. The Company does not use the equipment held in its portfolio, but holds it solely for lease and ultimate sale. In the course of marketing equipment that has come off-lease, management may determine at some point that re-leasing the assets may provide a superior return for investors and would then execute another lease. Upon entering into a new lease contract, management will estimate the residual value once again and resume depreciation. If, and when, the Company, at any time, determines that depreciation in value may have occurred with respect to an asset held-for-sale, the Company would review the value to determine whether a material reduction in value had occurred and recognize any appropriate impairment. All lease assets, including off-lease assets, are subject to the Company’s quarterly impairment analysis, as described below. Maintenance costs associated with the Fund’s portfolio of leased assets are expensed as incurred. Major additions and betterments are capitalized. Operating lease revenue is recognized on a straight-line basis over the term of the underlying leases. The initial lease terms will vary as to the type of equipment subject to the leases, the needs of the lessees and the terms to be negotiated, but initial leases are generally on terms from 36 to 120 months. The difference between rent received and rental revenue recognized is recorded as unearned operating lease income on the balance sheet. Operating leases are generally placed in a non-accrual status (i.e., no revenue is recognized) when payments are more than 90 days past due. Additionally, management considers the equipment underlying the lease contracts for impairment and periodically reviews the credit worthiness of all operating lessees with payments outstanding less than 90 days. Based upon management’s judgment, the related operating leases may be placed on non-accrual status. Leases placed on non-accrual status are only returned to an accrual status when the account has been brought current and management believes recovery of the remaining unpaid lease payments is probable. Until such time, revenues are recognized on a cash basis. Pr o v n o e o t u e m m p y i a m Initial direct costs: Incremental costs of a lease that would not have been incurred if the lease had not been obtained are capitalized and amortized over the lease term. All other costs associated with the execution of the Company’s leases are expensed as incurred. Asset valuation: Recorded values of the Company’s leased asset portfolio are reviewed each quarter to confirm the reasonableness of established residual values and to determine whether there is indication that an asset impairment might have taken place. The Company uses a variety of sources and considers many factors in evaluating whether the respective book values of its assets are appropriate. In addition, the Company may direct a residual value review at any time if it becomes aware of issues regarding the ability of a lessee to continue to make payments on its lease contract. An impairment loss is measured and recognized only if the estimated undiscounted future cash flows of the asset are less than the net book value. The estimated undiscounted future cash flows are the sum of the residual value of the asset at the end of the asset’s lease contract and undiscounted future rents from the existing lease contract. The residual value assumes, among other things, that the asset is utilized normally in an open, unrestricted and stable market. Short-term fluctuations in the marketplace are disregarded and it is assumed that there is no necessity either to dispose of a significant number of the assets, if held in quantity, simultaneously or to dispose of the asset quickly. Impairment is measured as the difference between the fair value (as determined by a valuation method using discounted estimated future cash flows, third party appraisals or comparable sales of similar assets as applicable based on asset type) of the asset and its carrying value on the measurement date. Upward adjustments for impairments recognized in prior periods are not made in any circumstances. Segment reporting: The Company is organized into one operating segment for the purpose of making operating decisions or assessing performance. Accordingly, the Company operates in one reportable operating segment in the United States. The primary geographic region in which the Company seeks leasing opportunities is North America. For the years ended December 31, 2023 and 2022, and as of December 31, 2023 and 2022, all of the Company’s current operating revenues and long-lived assets relate to customers domiciled in the United States. Investment in securities: From time to time, the Company may receive the right to purchase equity securities of its borrowers or receive warrants in connection with its lending arrangements. Investment in equity securities The Company’s equity securities registered for public sale with readily determinable fair values are measured at fair value with any changes in fair value recognized in the Company’s results of operations. The Company’s equity securities that do not have readily determinable fair values are measured at cost minus impairment and adjusted for changes in observable prices. Factors considered by the Managing Member in determining fair value include, but are not limited to, available financial information, the issuer’s ability to meet its current obligations and indications of the issuer’s subsequent ability to raise capital. As of December 31, 2023, equity securities totaled $24 thousand, all of which do not have readily determinable market value. As of December 31, 2022, equity securities totaled $37 thousand, which also included $24 thousand of equity securities which do not have readily determinable market value. During the respective years ended December 31, 2023 and 2022, the Company recorded $2 thousand and $23 thousand of unrealized losses on investments securities with readily determinable fair values, respectively. There were no fair value adjustments on investment securities that do not have readily determinable fair values during 2023 and 2022. Cumulatively, a total of $17 thousand was recorded to reduce the value of such investment securities held on December 31, 2023. The Company had no impairment adjustments on investment securities during the years ended December 31, 2023 and 2022. During the current year, the Company sold its readily determinable equity securities valued at approximately $11 thousand and realized losses of $1 thousand on such sale. There was no such sale during the prior year. Warrants Warrants owned by the Company are not registered for public sale, but are considered derivatives and are reflected at an estimated fair value on the balance sheet, as determined by the Managing Member. As of December 31, 2023 and 2022, the estimated fair value of the Company’s portfolio of warrants was de minimis. There were no changes recorded on fair valuation of the warrants during the year ended December 31, 2023. During the year ended December 31, 2022, the Company recorded unrealized losses of $2 thousand on fair valuation of its warrants. There were no warrant exercises during 2023 and 2022. Unearned operating lease income: The Company records prepayments on operating leases as a liability under the caption of unearned operating lease income. The liability is recorded when prepayments are received and recognized as operating lease revenue over the period to which the prepayments relate using a straight-line method. Income Taxes: The Company is treated as a partnership for federal income tax purposes. Pursuant to the provisions of Section 701 of the Internal Revenue Code, a partnership is not subject to federal income taxes. Accordingly, the Company has provided current franchise income taxes for only those states which levy income taxes on partnerships. For the years ended December 31, 2023 and 2022, the related provision for state income taxes was approximately $90 thousand and $80 thousand, respectively. The Company does not have any entity level uncertain tax positions. The Company files income tax returns in the U.S. federal jurisdiction and various state jurisdictions and is generally subject to examination by U.S. federal (or state and local) income tax authorities for three years from the filing of a tax return. The tax bases of the Company’s net assets and liabilities vary from the amounts presented in these financial statements at December 31, 2023 and 2022 as follows (in thousands): 2023 2022 Financial statement basis of net assets $ 7,806 $ 9,243 Tax basis of net assets (unaudited) 17,378 18,182 Difference $ (9,572) $ (8,939) The primary differences between the tax bases of net assets and the amounts recorded in the financial statements are the result of differences in accounting for syndication costs and differences between the depreciation methods used in the financial statements and the Company’s tax returns. The following reconciles the net income reported in these financial statements to the income reported on the Company’s federal tax return (unaudited) for the years ended December 31, 2023 and 2022 (in thousands): 2023 2022 Net income per financial statements $ 1,330 $ 1,166 Tax adjustments (unaudited): Adjustment to depreciation expense (522) — Provision for losses and doubtful accounts 4 (5) Adjustments to revenues (112) (193) Adjustments to gain on sales of assets 1,244 653 Other 20 40 Income per federal tax return (unaudited) $ 1,964 $ 1,661 Per Unit data: The Company issues only one class of Units, none of which are considered dilutive. Net income and distributions per Unit is based upon the weighted average number of Other Members Units outstanding during the year. Recent accounting pronouncements: In March 2020, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2020-03, Codification Improvements to Financial Instruments (“ASU 2020-03”). ASU 2020-03 improves and clarifies various financial instruments topics, including the current expected credit losses (CECL) standard issued in 2016. ASU 2020-03 includes seven different issues that describe the areas of improvement and the related amendments to GAAP that are intended to make the standards easier to understand and apply by eliminating inconsistencies and providing clarifications. The amendments have different effective dates. The Company adopted this new accounting guidance on January 1, 2023. Such adoption had no material impact on the Company’s financial statements and disclosures. In June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses (Topic 326) (“ASU 2016-13”). The main objective of this Update is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. To achieve this objective, the amendments in this Update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The amendments affect entities holding financial assets and equipment under operating leases that are not accounted for at fair value through net income. The amendments affect loans, debt securities, trade receivables, equipment under operating leases, off-balance-sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. The Company adopted this new accounting guidance on January 1, 2023. Such adoption had no material impact on the Company’s financial statements and disclosures. In November 2018, the FASB issued ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments — Credit Losses (“ASU 2018-19”). The new standard clarifies certain aspects of the new CECL impairment model in ASU 2016-13. The amendment clarifies that receivables arising from operating leases are within the scope of ASC 842, rather than ASC 326.

Concentration of credit risk and major customers: The Company leases equipment to lessees and provides debt financing to borrowers in diversified industries. Leases and notes receivable are subject to the Managing Member’s credit committee review. The leases provide for the return of the equipment to the Company upon default. As of December 31, 2023 and 2022, there were concentrations (greater than or equal to 10% as a percentage of total equipment cost) of equipment leased to lessees and/or financed for borrowers in certain industries as follows: Industry 2023 2022 Oil/Gas extraction 73 % 53 % Elec/Gas/Sanitation 19 % 14 % During 2023 and 2022, certain lessees and/or financial borrowers generated significant portions (defined as greater than or equal to 10%) of the Company’s total leasing and lending revenues, excluding gains or losses on disposition of assets, as follows: Percentage of Total Leasing and Lending Revenues Lessee Type of Equipment 2023 2022 Halliburton Overseas Limited Marine vessel 33 % 33 % AEP Generating Company Facility - Other 20 % 18 % GE Aviation Manufacturing 13 % 13 % Finger Lakes Railway Corp.

The Company utilizes a straight-line depreciation method over the term of the equipment lease for equipment under operating leases currently in its portfolio. Depreciation expense on the Company’s equipment totaled $1.5 million and $2.1 million for the years ended December 31, 2023 and 2022, respectively. The total for 2023 includes $117 thousand of additional depreciation recorded to reflect year-to-date changes in estimated residual values of certain equipment generating revenue under month-to-month extensions. Such estimated residual values of equipment associated with leases on month-to-month extensions are evaluated at least semi-annually, and depreciation recorded for the change in the estimated reduction in value.

Related Party Transactions	6. Related party transactions: The terms of the Operating Agreement provide that the Managing Member and/or affiliates are entitled to receive certain fees for equipment management and resale and for management of the Company. The Operating Agreement allows for the reimbursement of costs incurred by the Managing Member and/or affiliates for providing administrative services to the Company. Administrative services provided include Company accounting, investor relations, legal counsel and lease and equipment documentation. The Managing Member is not reimbursed for services whereby it is entitled to receive a separate fee as compensation for such services, such as management of investments. AFS and ATEL Leasing Corporation (“ALC”) are wholly owned subsidiaries of ATEL Capital Group and perform services for the Company on behalf of the Managing Member. Acquisition services, equipment management, lease administration and asset disposition services are performed by ALC; investor relations, communications and general administrative services are performed by AFS. Cost reimbursements to the Managing Member or its affiliates are based on its costs incurred in performing administrative services for the Company. These costs are allocated to each managed entity based on certain criteria such as total assets, number of investors or contributed capital based upon the type of cost incurred. The Managing Member believes that the costs reimbursed are the lower of (i) actual costs incurred on behalf of the Company or (ii) the amount the Company would be required to pay independent parties for comparable administrative services in the same geographic location. The Managing Member and/or affiliates earned fees and billed for reimbursements, pursuant to the Operating Agreement, during the years ended December 31, 2023 and 2022 as follows (in thousands): 2023 2022 Administrative costs reimbursed to Managing Member and/or affiliates $ 335 $ 378 Asset management fees to Managing Member 95 115 $ 430 $ 493

Non-Recourse Debt [Abstract]
Non-Recourse Debt	7. Non-recourse debt: At December 31, 2023, non-recourse debt consists of notes payable to financial institutions. The note payments are due in monthly installments. Interest on the note is 3.40% per annum. The note is secured by assignments of lease payments and pledges of assets. At December 31, 2023, gross operating lease rentals totaled approximately $173 thousand over the remaining lease terms and the carrying value of the pledged assets is $4.2 million. The note matures in 2024. The non-recourse debt does not contain any material financial covenants. The debt is secured by a specific lien granted by the Company to the non-recourse lender on (and only on) the discounted lease transactions. The lender has recourse only to the following collateral: the leased equipment; the related lease chattel paper; the lease receivables; and proceeds of the foregoing items. The non-recourse obligation is payable solely out of the respective specific security and the Company does not guarantee (nor is the Company otherwise contractually responsible for) the payment of the non-recourse debt as a general obligation or liability of the Company. Although the Company does not have any direct or general liability in connection with the non-recourse debt apart from the security granted, the Company is directly and generally liable and responsible for certain representations, warranties, and covenants made to the lender, such as warranties as to genuineness of the transaction parties’ signatures, as to the genuineness of the respective lease chattel paper or the transaction as a whole, or as to the Company’s good title to or perfected interest in the secured collateral, as well as similar representations, warranties and covenants typically provided by non-recourse borrowers and customary in the equipment finance industry, and are viewed by such industry as being consistent with non-recourse discount financing obligations. Accordingly, as there are no financial covenants or ratios imposed on the Company in connection with the non-recourse debt, the Company has determined that there are no material covenants with respect to the non-recourse debt that warrant footnote disclosure. Future minimum payments of non-recourse debt are as follows (in thousands): Principal Interest Total Through February 29, 2024 172 1 173 Total $ 172 $ 1 $ 173 The non-recourse debt balance represents the remaining portion of half of a $9.2 million non-recourse promissory note executed on May 20, 2019. The non-recourse promissory note was split evenly between the Fund and its affiliate, ATEL 14, LLC, and was used to pay off the senior long-term debt. The non-recourse promissory note is to be serviced by the cash flows generated under a renewed bareboat charter.

However, the Company has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote. The Managing Member knows of no facts or circumstances that would make the Company’s contractual commitments outside standard mutual covenants applicable to commercial transactions between businesses. Accordingly, the Company believes that these indemnification obligations are made in the ordinary course of business as part of standard commercial and industry practice, and that any potential liability under the Company’s similar commitments is remote. Should any such indemnification obligation become payable, the Company would separately record and/or disclose such liability in accordance with GAAP.

The Fund was authorized to issue up to 15,000,000 Units in addition to the Units issued to the initial Member. The Company has the right, exercisable at the Managing Member’s discretion, but not the obligation, to repurchase Units of a Unitholder who ceases to be a U.S. Citizen, for a price equal to 100% of the holder’s capital account. The Company is otherwise permitted, but not required, to repurchase Units upon a holder’s request. The repurchase of Fund units is made in accordance with Section 13 of the Amended and Restated Limited Liability Company Operating Agreement. The repurchase would be at the discretion of the Managing Member on terms it determines to be appropriate under given circumstances, in the event that the Managing Member deems such repurchase to be in the best interest of the Company; provided, the Company is never required to repurchase any Units. Upon the repurchase of any Units by the Fund, the tendered Units are cancelled. Units repurchased in prior periods were repurchased at amounts representing the original investment less cumulative distributions made to the Unitholder with respect to the Units. All Units repurchased during a quarter are deemed to be repurchased effective the last day of the preceding quarter, and are not deemed to be outstanding during, or entitled to allocations of net income, net loss or distributions for the quarter in which such repurchase occurs. The Fund’s net income or net losses are to be allocated 100% to the members. From the commencement of the Fund until the initial closing date, net income and net loss were allocated 99% to the Managing Member and 1% to the initial members. Commencing with the initial closing date, net income and net loss are to be allocated 92.5% to the members and 7.5% to the Managing Member. Fund distributions are to be allocated 7.5% to the Managing Member and 92.5% to the members. The Company commenced periodic distributions during the first quarter of 2012.

Fair Value Measurements

Fair Value Measurements	Dec. 31, 2023
Fair Value Measurements [Abstract]
Fair Value Measurements	11. Fair value measurements: Under applicable accounting standards, fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Fair value measurements and disclosures are based on a fair value hierarchy as determined by significant inputs used to measure fair value. The three levels of inputs within the fair value hierarchy are defined as follows: Level 1 — Quoted prices in active markets for identical assets or liabilities. An active market for the asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis, generally on a national exchange. Level 2 — Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuations in which all significant inputs are observable in the market. Level 3 — Valuation is modeled using significant inputs that are unobservable in the market. These unobservable inputs reflect the Company’s own estimates of assumptions that market participants would use in pricing the asset or liability. The Company’s valuation policy is determined by members of the Asset Management, Credit and Accounting departments. Whenever possible, the policy is to obtain quoted market prices in active markets to estimate fair values for recognition and disclosure purposes. Where quoted market prices in active markets are not available, fair values are estimated using discounted cash flow analyses, broker quotes, information from third party remarketing agents, third party appraisals of collateral and/or other valuation techniques. These techniques are significantly affected by certain of the Company’s assumptions, including discount rates and estimates of future cash flows. Potential taxes and other transaction costs are not considered in estimating fair values. As the Company is responsible for determining fair value, an analysis is performed on prices obtained from third parties. Such analysis is performed by asset management and credit department personnel who are familiar with the Company’s investments in equipment, notes receivable and equity securities of venture companies. The analysis may include a periodic review of price fluctuations and validation of numbers obtained from a specific third party by reference to multiple representative sources. At December 31, 2023 and 2022, the Company’s investment in equity securities were measured on a recurring basis. At December 31, 2022, the Company’s warrants were also measured at fair value on a recurring basis. Such calculated fair value of the Fund’s warrants was de minimis. In addition, certain equipment deemed impaired were measured at fair value on a non-recurring basis as of December 31, 2023 and 2022. The measurement methodology is as follows: Investment in equity securities (recurring) The Company’s investment securities registered for public sale with readily determinable fair values are measured at fair value with any changes in fair value recognized in the Company’s results of operations. As of December 31, 2023, all of such securities had been sold. As of December 31, 2022, the fair value of such investment securities totaled $14 thousand. Impaired lease and off-lease equipment (non-recurring) No additional impairment was recorded during the years ended December 31, 2023 and 2022 to further reduce the cost basis of certain manufacturing, and agriculture equipment deemed impaired. Level 1 Level 2 Level 3 December 31, Estimated Estimated Estimated 2023 Fair Value Fair Value Fair Value Assets measured at fair value on a non-recurring basis (in thousands): Impaired lease and off-lease equipment $ 10 $ — $ — $ 10 $ 10 $ — $ — $ 10 Level 1 Level 2 Level 3 December 31, Estimated Estimated Estimated 2022 Fair Value Fair Value Fair Value Assets measured at fair value on a non-recurring basis (in thousands): Impaired lease and off-lease equipment $ 25 $ — $ — $ 25 $ 25 $ — $ — $ 25 Under the Fair Value Measurements Topic of the FASB Accounting Standards Codification, the fair value of impaired lease assets were classified within Level 3 of the valuation hierarchy as the data sources utilized for the valuation of such assets reflect significant inputs that are unobservable in the market. Such valuation utilizes a market approach technique and uses inputs that reflect the sales price of similar assets sold by affiliates and/or information from third party remarketing agents not readily available in the market. The following tables summarize the valuation techniques and significant unobservable inputs used for the Company’s recurring and non-recurring fair value calculation/adjustments categorized as Level 3 in the fair value hierarchy at December 31, 2023 and 2022: December 31, 2023 Valuation Valuation Unobservable Input Values Name Frequency Technique Inputs (Weighted Average) Warrants Recurring Black-Scholes formulation Stock price $1.27 Exercise price $1.00 Time to maturity (in years) 0.35 Annualized volatility 48.01% Lease and Off-lease equipment Non-recurring Market Approach Third Party Agents' Pricing $0 - $10,000 Quotes - per equipment (total of $10,000) Equipment Condition Poor to Average December 31, 2022 Valuation Valuation Unobservable Input Values Name Frequency Technique Inputs (Weighted Average) Warrants Recurring Black-Scholes formulation Stock price $1.27 Exercise price $1.00 Time to maturity (in years) 1.35 Annualized volatility 50.99% Lease and Off-lease equipment Non-recurring Market Approach Third Party Agents' Pricing $0 - $25,000 Quotes - per equipment (total of $25,000) Equipment Condition Poor to Average The following disclosure of the estimated fair value of financial instruments is made in accordance with the guidance provided by the Financial Instruments Topic of the FASB Accounting Standards Codification. Fair value estimates, methods and assumptions, set forth below for the Company’s financial instruments, are made solely to comply with the requirements of the Financial Instruments Topic and should be read in conjunction with the Company’s financial statements and related notes. The Company determines the estimated fair value amounts by using market information and valuation methodologies that it considers appropriate and consistent with the fair value accounting guidance. Considerable judgment is required to interpret market data to develop the estimates of fair value. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. Cash and cash equivalents The recorded amounts of the Company’s cash and cash equivalents approximate fair value because of the liquidity and short-term maturity of these instruments. Non-recourse debt The fair value of the Company’s non-recourse debt is estimated using discounted cash flow analyses, based upon current market borrowing rates for similar types of borrowing arrangements. Commitments and Contingencies Management has determined that no recognition for the fair value of the Company’s loan commitments is necessary because their terms are made on a market rate basis and require borrowers to be in compliance with the Company’s credit requirements at the time of funding. The fair value of contingent liabilities (or guarantees) is not considered material because management believes there has been no event that has occurred wherein a guarantee liability has been incurred or will likely be incurred.

Summary of Significant Accounting Policies [Abstract]
Basis of Presentation	Basis of presentation: The accompanying balance sheets as of December 31, 2023 and 2022, and the related statements of income, changes in members’ capital, and cash flows for the years then ended, have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and the rules and regulations of the Securities and Exchange Commission. Certain prior year amounts may have been reclassified to conform to the current year presentation. These reclassifications had no significant effect on the reported financial position or results from operations. Footnote and tabular amounts are presented in thousands, except as to Units and per Unit data In preparing the accompanying financial statements, the Company has reviewed, as determined necessary by the Managing Member, events that have occurred after December 31, 2023, up until the issuance of the financial statements. No events were noted which would require disclosure in the footnotes to the financial statements.
Cash and Cash Equivalents	Cash and cash equivalents: Cash and cash equivalents include cash in banks and cash equivalent investments such as U.S. Treasury instruments with original and/or purchased maturities of ninety days or less.
Use of Estimates	Use of Estimates: The preparation of the financial statements in conformity 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 at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from the estimates. Such estimates primarily relate to the determination of residual values at the end of the lease term and expected future cash flows used for impairment analysis purposes and for determination of the allowance for doubtful accounts on accounts receivable.
Accounts Receivable	Accounts receivable: Accounts receivable represent the amounts billed under operating lease which is currently due to the Company. Allowances for doubtful accounts are typically established based on historical charge off and collection experience and the collectability of specifically identified lessees, and invoiced amounts. Accounts receivable deemed uncollectible are generally charged off against the allowance on a specific identification basis. Recoveries of amounts that were previously written-off are recorded as other income in the period received.
Segment Reporting	Segment reporting: The Company is organized into one operating segment for the purpose of making operating decisions or assessing performance. Accordingly, the Company operates in one reportable operating segment in the United States. The primary geographic region in which the Company seeks leasing opportunities is North America. For the years ended December 31, 2023 and 2022, and as of December 31, 2023 and 2022, all of the Company’s current operating revenues and long-lived assets relate to customers domiciled in the United States.
Investment in Securities	Investment in securities: From time to time, the Company may receive the right to purchase equity securities of its borrowers or receive warrants in connection with its lending arrangements. Investment in equity securities The Company’s equity securities registered for public sale with readily determinable fair values are measured at fair value with any changes in fair value recognized in the Company’s results of operations. The Company’s equity securities that do not have readily determinable fair values are measured at cost minus impairment and adjusted for changes in observable prices. Factors considered by the Managing Member in determining fair value include, but are not limited to, available financial information, the issuer’s ability to meet its current obligations and indications of the issuer’s subsequent ability to raise capital. As of December 31, 2023, equity securities totaled $24 thousand, all of which do not have readily determinable market value. As of December 31, 2022, equity securities totaled $37 thousand, which also included $24 thousand of equity securities which do not have readily determinable market value. During the respective years ended December 31, 2023 and 2022, the Company recorded $2 thousand and $23 thousand of unrealized losses on investments securities with readily determinable fair values, respectively. There were no fair value adjustments on investment securities that do not have readily determinable fair values during 2023 and 2022. Cumulatively, a total of $17 thousand was recorded to reduce the value of such investment securities held on December 31, 2023. The Company had no impairment adjustments on investment securities during the years ended December 31, 2023 and 2022. During the current year, the Company sold its readily determinable equity securities valued at approximately $11 thousand and realized losses of $1 thousand on such sale. There was no such sale during the prior year. Warrants Warrants owned by the Company are not registered for public sale, but are considered derivatives and are reflected at an estimated fair value on the balance sheet, as determined by the Managing Member. As of December 31, 2023 and 2022, the estimated fair value of the Company’s portfolio of warrants was de minimis. There were no changes recorded on fair valuation of the warrants during the year ended December 31, 2023. During the year ended December 31, 2022, the Company recorded unrealized losses of $2 thousand on fair valuation of its warrants. There were no warrant exercises during 2023 and 2022.
Unearned Operating Lease Income	Unearned operating lease income: The Company records prepayments on operating leases as a liability under the caption of unearned operating lease income. The liability is recorded when prepayments are received and recognized as operating lease revenue over the period to which the prepayments relate using a straight-line method.
Income Taxes	Income Taxes: The Company is treated as a partnership for federal income tax purposes. Pursuant to the provisions of Section 701 of the Internal Revenue Code, a partnership is not subject to federal income taxes. Accordingly, the Company has provided current franchise income taxes for only those states which levy income taxes on partnerships. For the years ended December 31, 2023 and 2022, the related provision for state income taxes was approximately $90 thousand and $80 thousand, respectively. The Company does not have any entity level uncertain tax positions. The Company files income tax returns in the U.S. federal jurisdiction and various state jurisdictions and is generally subject to examination by U.S. federal (or state and local) income tax authorities for three years from the filing of a tax return. The tax bases of the Company’s net assets and liabilities vary from the amounts presented in these financial statements at December 31, 2023 and 2022 as follows (in thousands): 2023 2022 Financial statement basis of net assets $ 7,806 $ 9,243 Tax basis of net assets (unaudited) 17,378 18,182 Difference $ (9,572) $ (8,939) The primary differences between the tax bases of net assets and the amounts recorded in the financial statements are the result of differences in accounting for syndication costs and differences between the depreciation methods used in the financial statements and the Company’s tax returns. The following reconciles the net income reported in these financial statements to the income reported on the Company’s federal tax return (unaudited) for the years ended December 31, 2023 and 2022 (in thousands): 2023 2022 Net income per financial statements $ 1,330 $ 1,166 Tax adjustments (unaudited): Adjustment to depreciation expense (522) — Provision for losses and doubtful accounts 4 (5) Adjustments to revenues (112) (193) Adjustments to gain on sales of assets 1,244 653 Other 20 40 Income per federal tax return (unaudited) $ 1,964 $ 1,661
Per Unit Data	Per Unit data: The Company issues only one class of Units, none of which are considered dilutive. Net income and distributions per Unit is based upon the weighted average number of Other Members Units outstanding during the year.
Recent Accounting Pronouncements	Recent accounting pronouncements: In March 2020, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2020-03, Codification Improvements to Financial Instruments (“ASU 2020-03”). ASU 2020-03 improves and clarifies various financial instruments topics, including the current expected credit losses (CECL) standard issued in 2016. ASU 2020-03 includes seven different issues that describe the areas of improvement and the related amendments to GAAP that are intended to make the standards easier to understand and apply by eliminating inconsistencies and providing clarifications. The amendments have different effective dates. The Company adopted this new accounting guidance on January 1, 2023. Such adoption had no material impact on the Company’s financial statements and disclosures. In June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses (Topic 326) (“ASU 2016-13”). The main objective of this Update is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. To achieve this objective, the amendments in this Update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The amendments affect entities holding financial assets and equipment under operating leases that are not accounted for at fair value through net income. The amendments affect loans, debt securities, trade receivables, equipment under operating leases, off-balance-sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. The Company adopted this new accounting guidance on January 1, 2023. Such adoption had no material impact on the Company’s financial statements and disclosures. In November 2018, the FASB issued ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments — Credit Losses (“ASU 2018-19”). The new standard clarifies certain aspects of the new CECL impairment model in ASU 2016-13. The amendment clarifies that receivables arising from operating leases are within the scope of ASC 842, rather than ASC 326.
Credit Risk	Credit risk: Financial instruments that potentially subject the Company to concentrations of credit risk include cash and cash equivalents, operating lease receivables and accounts receivable. The Company places the majority of its cash deposits in noninterest-bearing accounts with financial institutions that have no less than $10 billion in assets. Such deposits are insured up to $250 thousand. The remainder of the Funds’ cash is temporarily invested in U.S. Treasury denominated instruments. The concentration of such deposits and temporary cash investments is not deemed to create a significant risk to the Company. Accounts receivable represent amounts due from lessees in various industries, related to equipment on operating leases.
Equipment on Operating Leases and Related Revenue Recognition	Equipment on operating leases and related revenue recognition: Equipment subject to operating leases is stated at cost. Depreciation is being recognized on a straight-line method over the terms of the related leases to the equipment’s estimated residual values. Off-lease equipment is generally not subject to depreciation. The Company depreciates all lease assets, in accordance with guidelines consistent with Accounting Standards Codification (ASC) 360-10-35-3, over the periods of the lease terms contained in each asset’s respective lease contract to the estimated residual value at the end of the lease contract. All lease assets are purchased only concurrent with the execution of a lease commitment by the lessee. Thus, the original depreciation period corresponds with the term of the original lease. Once the term of an original lease contract is completed, the subject property is typically sold to the existing user, re-leased to the existing user, or, when off-lease, is held for sale. Assets which are re-leased continue to be depreciated using the terms of the new lease agreements and the estimated residual values at the end of the new lease terms, adjusted downward as necessary. Assets classified as held-for-sale are carried at the lower of carrying amount, or the fair value less cost to sell. The Company does not use the equipment held in its portfolio, but holds it solely for lease and ultimate sale. In the course of marketing equipment that has come off-lease, management may determine at some point that re-leasing the assets may provide a superior return for investors and would then execute another lease. Upon entering into a new lease contract, management will estimate the residual value once again and resume depreciation. If, and when, the Company, at any time, determines that depreciation in value may have occurred with respect to an asset held-for-sale, the Company would review the value to determine whether a material reduction in value had occurred and recognize any appropriate impairment. All lease assets, including off-lease assets, are subject to the Company’s quarterly impairment analysis, as described below. Maintenance costs associated with the Fund’s portfolio of leased assets are expensed as incurred. Major additions and betterments are capitalized. Operating lease revenue is recognized on a straight-line basis over the term of the underlying leases. The initial lease terms will vary as to the type of equipment subject to the leases, the needs of the lessees and the terms to be negotiated, but initial leases are generally on terms from 36 to 120 months. The difference between rent received and rental revenue recognized is recorded as unearned operating lease income on the balance sheet. Operating leases are generally placed in a non-accrual status (i.e., no revenue is recognized) when payments are more than 90 days past due. Additionally, management considers the equipment underlying the lease contracts for impairment and periodically reviews the credit worthiness of all operating lessees with payments outstanding less than 90 days. Based upon management’s judgment, the related operating leases may be placed on non-accrual status. Leases placed on non-accrual status are only returned to an accrual status when the account has been brought current and management believes recovery of the remaining unpaid lease payments is probable. Until such time, revenues are recognized on a cash basis. Pr o v n o e o t u e m m p y i a m
Initial Direct Costs	Initial direct costs: Incremental costs of a lease that would not have been incurred if the lease had not been obtained are capitalized and amortized over the lease term. All other costs associated with the execution of the Company’s leases are expensed as incurred.
Asset Valuation	Asset valuation: Recorded values of the Company’s leased asset portfolio are reviewed each quarter to confirm the reasonableness of established residual values and to determine whether there is indication that an asset impairment might have taken place. The Company uses a variety of sources and considers many factors in evaluating whether the respective book values of its assets are appropriate. In addition, the Company may direct a residual value review at any time if it becomes aware of issues regarding the ability of a lessee to continue to make payments on its lease contract. An impairment loss is measured and recognized only if the estimated undiscounted future cash flows of the asset are less than the net book value. The estimated undiscounted future cash flows are the sum of the residual value of the asset at the end of the asset’s lease contract and undiscounted future rents from the existing lease contract. The residual value assumes, among other things, that the asset is utilized normally in an open, unrestricted and stable market. Short-term fluctuations in the marketplace are disregarded and it is assumed that there is no necessity either to dispose of a significant number of the assets, if held in quantity, simultaneously or to dispose of the asset quickly. Impairment is measured as the difference between the fair value (as determined by a valuation method using discounted estimated future cash flows, third party appraisals or comparable sales of similar assets as applicable based on asset type) of the asset and its carrying value on the measurement date. Upward adjustments for impairments recognized in prior periods are not made in any circumstances.
