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 September 30, 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, 6,530,257 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 receive compensation for services rendered and reimbursements for costs incurred on behalf of the Company (See Note 5). 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. These unaudited interim financial statements should be read in conjunction with the financial statements and notes thereto contained in the report on Form 10-K for the year ended December 31, 2022, filed with the Securities and Exchange Commission.

Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of significant accounting policies ​ Basis of presentation: ​ The accompanying unaudited financial statements have been prepared in accordance with accounting principles generally accepted in the United States (‘‘GAAP’’) for interim financial information and with the instructions to Form 10-Q as mandated by the Securities and Exchange Commission. The unaudited interim financial statements reflect all adjustments which are, in the opinion of the Managing Member, necessary for a fair statement of financial position and results of operations for the interim periods presented. All such adjustments are of a normal recurring nature. Operating results for the three and nine months ended September 30, 2023 are not necessarily indicative of the results to be expected for the full year. Certain prior period amounts may have been reclassified to conform to the current period presentation. These reclassifications had no significant effect on the reported financial position or results of 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 September 30, 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. 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 three and nine months ended September 30, 2023 and 2022, and as of September 30, 2023 and December 31, 2022, all of the Company’s current operating revenues and long-lived assets relate to customers domiciled in the United States. Accounts receivable: Accounts receivable represent the amounts billed under the 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. 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. The Company had $34 thousand and $37 thousand of purchased securities at September 30, 2023 and December 31, 2022, respectively. Such amounts included investment securities which do not have readily determinable market value totaling $23 thousand at both September 30, 2023 and December 31, 2022. During the respective three months ended September 30, 2023 and 2022, the Company recorded $4 thousand and $3 thousand of unrealized losses on investment securities with readily determinable fair values. During the respective nine months ended September 30, 2023 and 2022, the Company recorded $3 thousand and $24 thousand of unrealized losses on such investment securities. There were no fair value adjustments on investment securities that do not have readily determinable fair values during the three and nine months ended September 30, 2023 and 2022. Cumulatively, a total of $17 thousand was recorded to reduce the value of such investment securities held on September 30, 2023. The Company had no impairment adjustments on investment securities during the three and nine months ended September 30, 2023 and 2022. 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 September 30, 2023 and December 31, 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 three and nine months ended September 30, 2023. In addition, there were no changes recorded on fair valuation of the warrants during the three months ended September 30, 2022. The Company recorded unrealized losses of $2 thousand on fair valuation of its warrants during the nine months ended September 30, 2022. There were no warrants exercises during the three and nine months ended September 30, 2023 and 2022. 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 concentration of such deposits 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 the 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. 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. Fair value: 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. 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. 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. ​

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.

Non-Recourse Debt [Abstract]
Non-Recourse Debt	6. Non-recourse debt: ​ At September 30, 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 September 30, 2023, gross operating lease rentals totaled approximately $432 thousand over the remaining lease terms, and the carrying value of the pledged assets is $4.4 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 Three months ending December 31, 2023 ​ $ 256 ​ $ 3 ​ $ 259 Year ending December 31, 2024 ​ ​ 172 ​ ​ 1 ​ ​ 173 Total ​ $ 428 ​ $ 4 ​ $ 432 ​ 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.

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.

Fair Value Measurements [Abstract]
Fair Value Measurements	9. 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. ​ At September 30, 2023 and December 31, 2022, the Company’s warrants and investment in equity securities were measured on a recurring basis. In addition, certain equipment deemed impaired were measured at fair value on a non-recurring basis as of September 30, 2023 and December 31, 2022. The measurement methodology is as follows: Warrants (recurring) Warrants owned by the Company are not registered for public sale but are considered derivatives and are carried on the balance sheet at an estimated fair value at the end of the period. The valuation of the warrants was determined using a Black-Scholes formulation of value based upon the stock price(s), the exercise price(s), the volatility of comparable venture companies, and a risk free interest rate for the term(s) of the warrant exercise(s). At September 30, 2023 and December 31, 2022, the calculated fair value of the Fund’s warrants was de minimis. 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 September 30, 2023 and December 31, 2022, the fair value of such investment securities totaled $11 thousand and $14 thousand, respectively. Such valuations are classified within Level 1 of the valuation hierarchy. Unrealized losses of $4 thousand and $3 thousand were recorded on such securities during the three months ended September 30, 2023 and 2022, respectively. Unrealized losses of $3 thousand and $24 thousand were recorded during the nine months ended September 30, 2023 and 2022, respectively. Impaired lease and off-lease equipment (non-recurring) ​ No additional impairment was recorded during the three and nine months ended September 30, 2023 and 2022 to further reduce the cost basis of railcars and certain manufacturing, and agriculture equipment deemed impaired. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Level 1 Level 2 Level 3 ​ ​ September 30 ​ 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 ​ $ 18 ​ $ — ​ $ — ​ $ 18 ​ ​ $ 18 ​ $ — ​ $ — ​ $ 18 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 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 September 30, 2023 and December 31, 2022: ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2023 ​ Valuation ​ Valuation ​ Unobservable ​ Range of 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) ​ 0.60 ​ ​ ​ ​ Annualized volatility ​ 46.88% ​ ​ ​ ​ ​ ​ ​ ​ Lease and Off-lease equipment Non-recurring Market Approach Third Party Agents' Pricing ​ $0 - $18,000 ​ ​ ​ ​ ​ Quotes - per equipment ​ (total of $18,000) ​ ​ ​ ​ ​ Equipment Condition ​ Poor to Average ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2022 ​ Valuation ​ Valuation ​ Unobservable ​ Range of 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. ​ Investment in securities The Company's purchased securities registered for public sale with readily determinable fair value are carried at fair value. These investment securities are valued based on their quoted market price. 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 unaudited financial statements have been prepared in accordance with accounting principles generally accepted in the United States (‘‘GAAP’’) for interim financial information and with the instructions to Form 10-Q as mandated by the Securities and Exchange Commission. The unaudited interim financial statements reflect all adjustments which are, in the opinion of the Managing Member, necessary for a fair statement of financial position and results of operations for the interim periods presented. All such adjustments are of a normal recurring nature. Operating results for the three and nine months ended September 30, 2023 are not necessarily indicative of the results to be expected for the full year. Certain prior period amounts may have been reclassified to conform to the current period presentation. These reclassifications had no significant effect on the reported financial position or results of 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 September 30, 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.
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 three and nine months ended September 30, 2023 and 2022, and as of September 30, 2023 and December 31, 2022, all of the Company’s current operating revenues and long-lived assets relate to customers domiciled in the United States.
Accounts Receivable	Accounts receivable: Accounts receivable represent the amounts billed under the 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.
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. The Company had $34 thousand and $37 thousand of purchased securities at September 30, 2023 and December 31, 2022, respectively. Such amounts included investment securities which do not have readily determinable market value totaling $23 thousand at both September 30, 2023 and December 31, 2022. During the respective three months ended September 30, 2023 and 2022, the Company recorded $4 thousand and $3 thousand of unrealized losses on investment securities with readily determinable fair values. During the respective nine months ended September 30, 2023 and 2022, the Company recorded $3 thousand and $24 thousand of unrealized losses on such investment securities. There were no fair value adjustments on investment securities that do not have readily determinable fair values during the three and nine months ended September 30, 2023 and 2022. Cumulatively, a total of $17 thousand was recorded to reduce the value of such investment securities held on September 30, 2023. The Company had no impairment adjustments on investment securities during the three and nine months ended September 30, 2023 and 2022. 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 September 30, 2023 and December 31, 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 three and nine months ended September 30, 2023. In addition, there were no changes recorded on fair valuation of the warrants during the three months ended September 30, 2022. The Company recorded unrealized losses of $2 thousand on fair valuation of its warrants during the nine months ended September 30, 2022. There were no warrants exercises during the three and nine months ended September 30, 2023 and 2022.
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 concentration of such deposits 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 the 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.
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.
Fair Value	Fair value: 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. 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.

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. ​
