PART I

Item 1. BUSINESS

General Development of Business

ATEL 15, LLC (the “Company” or the “Fund”) was formed under the laws of the state of California on March 4, 2011 (“Date of Inception”) for the purpose of equipment financing 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, LLC (“AFS”), a wholly-owned subsidiary of ATEL Capital Group. The Fund may continue until terminated in accordance with the provisions of 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 4, 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, 2017, cumulative gross contributions, less rescissions and repurchases (net of distributions paid and allocated syndication costs, as applicable), totaling $66.0 million (inclusive of the $500 initial Member’s capital investment) have been received. As of the same date, 6,557,057 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 members, with any balance remaining after required minimum distributions to be used to purchase additional investments during the Reinvestment Period (ending six calendar years after the completion of the Company’s public offering of Units) and (iii) provide additional cash distributions following the Reinvestment Period and until all investment portfolio assets has been sold or otherwise disposed. The Company is governed by the ATEL 15, LLC amended and restated Limited Liability Company Operating Agreement dated October 28, 2011 (the “Operating Agreement”).

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 7, Related party transaction as set forth in Part II, Item 8, Financial Statements and Supplemental Data). 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.

Narrative Description of Business

The Company has acquired and intends to acquire various types of new and used equipment subject to leases and to make loans secured by equipment acquired by its borrowers. The Company’s primary investment objective is to acquire investments primarily in low-technology, low-obsolescence equipment such as the core operating equipment used by companies in the manufacturing, mining and transportation industries. A portion of the portfolio will include some more technology-dependent equipment such as certain types of communications equipment, medical equipment, manufacturing equipment and office equipment. The Company will also seek investments in equipment or financing of equipment and business involving “green technologies” such as those involved in the following activities: materials recycling, water purification, sewage treatment pollution radiation, gas and other emission treatment, solid waste management, renewable energy generation, as well as many other similar industries and activities.

The Company only purchases equipment under pre-existing leases or for which a lease will be entered into concurrently at the time of the purchase. Through December 31, 2017, the Company had purchased equipment with a total acquisition price of $64.8 million. The Company had also funded investments in notes receivable totaling $9.4 million through December 31, 2017.

1

As of the date of the final commitment of its proceeds from the sale of Units, the Company’s objective is to have at least 75% of its investment portfolio (by cost) consist of equipment leased to lessees that the Manager deems to be high quality corporate creditors and/or leases guaranteed by such high quality corporate creditors. High quality corporate creditors are lessees or guarantors who have a credit rating by Moody’s Investors Service, Inc. of “Baa3” or better, or the credit equivalent as determined by the Manager, or are public and private corporations with substantial revenues and histories of profitable operations, as well as established hospitals with histories of profitability or municipalities. The remaining 25% of the initial investment portfolio may include equipment lease transactions, real property single tenant net leases and other debt or equity financing for companies which, although deemed creditworthy by the Manager, would not satisfy the specific credit criteria for the portfolio described above. Included in this 25% of the portfolio may be growth capital financing investments. No more than 20% of the initial portfolio, by cost, will consist of these growth capital financing investments and no more than 20% of the portfolio, by cost, will consist of real estate investments. The Company’s objective is to invest approximately 25% of its capital in assets that involve “green” technologies or applications as discussed above.

The equipment financing industry is highly competitive. Equipment manufacturers, corporations, partnerships and others offer users an alternative to the purchase of most types of equipment with payment terms that vary widely depending on the type of financing, the lease or loan term and type of equipment. The ability of the Company to keep the equipment leased and the terms of purchase, lease and sale of equipment depends on various factors (many of which neither the Managing Member nor the Company can control), such as general economic conditions, including the effects of inflation or recession, and fluctuations in supply and demand for various types of equipment resulting from, among other things, technological and economic obsolescence.

The Managing Member will use its best efforts to diversify lessees by geography and industry and to maintain an appropriate balance and diversity in the types of equipment acquired and the types of leases entered into by the Company, and will apply the following policies: (i) The Managing Member will seek to limit the amount invested in equipment or property leased to any single lessee to not more than 20% of the aggregate purchase price of investments as of the final commitment of net offering proceeds; (ii) in no event will the Company’s equity investment in equipment or property leased to a single lessee exceed an amount equal to 20% of the maximum capital from the sale of Units (or $30,000,000); and (iii) the Managing Member will seek to invest not more than 20% of the aggregate purchase price of equipment in equipment acquired from a single manufacturer. However, this last limitation is a general guideline only, and the Company may acquire equipment from a single manufacturer in excess of the stated percentage during the offering period and before the offering proceeds are fully invested, or if the Managing Member deems such a course of action to be in the Company’s best interest.

The primary geographic region in which the Company seeks leasing opportunities is North America. All of the Company’s current operating revenues and long-lived assets relate to customers domiciled in the United States.

The business of the Company is not seasonal. The Company has no full time employees. Employees of the Managing Member and affiliates provide the services the Company requires to effectively operate. The cost of these services is reimbursed by the Company to the Managing Member and affiliates per the Operating Agreement.

For further information refer to the financial statements and the footnotes.

PART II

Market Information

There are certain material conditions and restrictions on the transfer of Units imposed by the terms of the Operating Agreement. Consequently, there is no public market for Units and it is not anticipated that a public market for Units will develop. In the absence of a public market for the Units, there is no currently ascertainable fair market value for the Units.

Fund Valuation

Background to Fund Valuation

The Financial Industry Regulatory Authority (“FINRA”), in conjunction with the Securities and Exchange Commission (“SEC”) updated rules for the presentation of account statement values relative to pricing of Direct Placement Program (“DPP”) shares. Under FINRA Notice 15-02 (the “Notice”) the SEC approved amendments to National Association of Securities Dealers (“NASD”) Rule 2340, Customer Account Statements, and FINRA rule 2310, which address a FINRA member firm’s participation in a public offering of a DPP. In summary, the amendments require a FINRA member firm to include in the account statements for customers holding DPP securities a per share value for the DPP. This per share value must be prepared by, or with the material assistance or confirmation of, a third-party valuation expert or service. The results of this valuation must be disclosed in the issuer’s reports filed under the Securities Exchange Act of 1934. A valuation in compliance with the Notice must be undertaken and published on at least an annual basis.

The effective date of the Notice was April 11, 2016.

Methodologies

Broker dealers are required to provide a per share estimated value on the customer account statements for each non-listed DPP security held by their customers. Such estimated value must have been developed in a manner reasonably designed to provide a reliable value. Two valuation methodologies have been defined by FINRA, which by such designation are presumed to be reliable.

Net Investment Methodology

The amendments to NASD Rule 2340(c)(1)(A) require “net investment” to be based on the “amount available for investment” percentage disclosed in the “Estimated Use of Proceeds” section of the issuer’s offering prospectus. In essence, such value is equal to the offering price less selling commissions, other offering and organization expenses, and capital reserves. This method may be used for up to 150 days following the second anniversary of a Fund breaking escrow.

Appraised Value Methodology

As amended, Rule NASD 2340(c)(1)(B) requires that the per share estimated value disclosed in an issuer’s most recent periodic or current report be based upon an appraisal of the assets and liabilities of the program by, or with the material assistance or confirmation of, a third-party valuation expert or service, in conformity with standard industry valuation practice as it relates to both the aforementioned assets and liabilities. No later than 150 days following the second anniversary of the issuer’s break of escrow for its minimum offering, this methodology must be used to establish the required estimated values.

Unit Valuation

The per Unit valuation estimate for ATEL 15, LLC has been conducted, and the results disclosed herein, in compliance with the mandates of the Notice.

For ATEL 15, LLC, its estimated value per Unit reflects the Manager’s estimate of current portfolio valuation of all assets and liabilities of the Fund, calculated on a per Unit basis, and as such, does not represent a market value for the Units and may not accurately reflect the value of the Fund Units to the Unit holders if held over time to Fund maturity.

6

In connection with any estimate of per Unit value, Unit holders and all parties are reminded that no public market for the Units exists. Additionally, in order to preserve the Fund’s pass-through status for federal income tax purposes, the Fund will not permit a secondary market or the substantial equivalent of a secondary market for the Units. In the absence of a public market for the Units, there is no currently ascertainable fair market value for the Units.

The estimate of per Unit value does not take into account any extraordinary potential future business activity of the Fund; rather the valuation represents a snapshot view of the Fund’s portfolio as of the valuation date. In addition, the Fund does not include any analysis of the distributions that have already been paid by the Fund, nor the anticipated returns to Unit holder over the full course of the Fund life cycle, which will be dependent on many factors.

Disclosure

The estimated value per Unit reported in this Form 10-K has been calculated using the “Appraised Value Methodology” described above under “Methodologies” above, as of December 31, 2017.

ATEL 15, LLC, will satisfy the disclosure requirements for providing estimated per Unit values pursuant to the Notice as follows:

For these disclosures, subsequent to the Fund’s initial compliance with FINRA 15-02, annual disclosures of estimated per Unit values, through the termination of the Fund; will be accomplished and included on an annual basis in a document filed with the Securities and Exchange Commission available to the public.

Specifics Underlying Valuation Methodology:

Notes and Explanation of Valuation Components and Calculation

Projected future cash flows have been discounted back to present value at discount rates based on like-term U.S. Treasury yields (as of the valuation date) plus a 400 basis point spread, to account for the credit risk differentials between the instrument being valued and U.S. Treasury security yields.

Residual values assumptions used in the cash flow projections are as follows:

For On-Lease and Month-to-Month Lease:  Considers realized residual as a percent of book residual of 165.9%, based on ATEL’s historical track record as of December 31, 2017.

For Off-Lease:  A fair value of off-lease equipment based upon estimates from ATEL’s seasoned Asset Management Group.

Special Situation Leases:  The valuation of certain leases has been performed outside of the above noted protocol based upon specific lease assumptions different than the macro assumptions above, due to the specific situations of those leases.

ATEL 15, LLC Unit Valuation

The Manager’s estimated per Unit value of ATEL 15, LLC at December 31, 2017 as determined, and derived under the guidelines of the Appraised Value Methodology, and pursuant to the above specific enumerated component valuation methodologies and calculations, equals $5.37. An independent national public accounting firm with valuation expertise was retained to examine, attest and confirm ATEL 15, LLC’s per Unit valuation and its component methodologies and calculation as it relates to compliance with the regulatory mandate defined in the Notice. In this regard, they examined the components of the valuation methodologies and determined them to be reasonable and within industry standards. Other component attributes, including the bases and related key assumptions of the calculation were tested for their completeness, underlying documentation support and mathematical accuracy. Upon completion of their efforts, their attestation report confirmed that the per unit valuation of ATEL 15, LLC, and the related notes, in all material respects, was based upon industry practice as described in the Manager’s valuation approach.

Disclaimer

The foregoing Fund per Unit valuation has been performed solely for the purpose of providing an estimated value per Unit in accordance with a regulatory mandate, in order to provide the broker dealer and custodian community with a valuation on a reasonable and attested basis for use in assigning an estimation of a Unit holder’s account value. Any report or disclosure of such estimated per Unit valuation is to be accompanied by statements that the value does not represent an estimate of the amount a Unit holder would receive if the Unit holder were to seek to sell the Units, and that the Fund intends to liquidate its assets in the ordinary course of its business and over the Fund’s term. Further, each statement of the Fund’s estimated per Unit valuation is to be accompanied by a disclosure that there can be no assurance as to (1) when the Fund will be fully liquidated, (2) the amount the Fund may actually receive if and when the Fund seeks to liquidate its assets, (3) the amount of lease or loan payments the Fund will actually receive over the remaining term, (4) the amount of asset disposition proceeds the Fund will actually receive over the remaining term, and (5) the amounts that may actually be received in distributions by Unit holders over the course of the remaining term.

Distributions

The members of record are entitled to certain distributions as provided under the Operating Agreement. The Company commenced periodic distributions beginning with the month of January 2012. Additional distributions have been consistently made through December 31, 2017.

Cash distributions were paid by the Fund to members of record as of November 30, 2017, and paid through December 31, 2017. Distributions may be characterized for tax, accounting and economic purposes as a return of capital, a return on capital (including escrow interest) or a portion of each. Generally, the portion of each cash distribution by a company which exceeds its net income for the fiscal period would constitute a return of capital.

The Fund is required by the terms of its Operating Agreement to distribute the net cash flow generated by its investments in certain minimum amounts during the Reinvestment Period before it can reinvest its operating cash flow in additional portfolio assets. See the discussion in the ATEL 15, LLC Prospectus dated October 28, 2011 (“Prospectus”) under “Income, Losses and Distributions — Reinvestment.” Accordingly, the amount of cash flow from Fund investments distributed to members will not be available for reinvestment in additional portfolio assets.

8

The Fund, as required by the terms of its Operating Agreement, must distribute the net cash flow generated by its investments to certain minimum amounts during the Reinvestment Period. This must be done before any reinvestment of operating cash flow in additional portfolio assets as distributions to Members from Fund investments will not be available for reinvestment in additional portfolio assets.

As net cash flows from operations are anticipated to fluctuate during the remaining life of the Fund, distributions will only be paid on an annual basis beginning with March of 2018. A distribution equal to 2% of the total original capital contribution will be paid in early March 2018. The remaining amount to be distributed for 2018 will be determined in December 2018 and paid in January 2019. The amount of all future distributions is dependent upon the timing of lease payments, renewals and asset sales, which will vary during the year.

Through December 31, 2017, the Fund has made annualized distributions of 9% of the investors’ original capital contributions, commencing with the closing of the Fund. At this time, early investors have received distributions in excess of 53% of their original investment.

Cash distributions were based on current and anticipated gross revenues from the leases and loans acquired. During the Fund’s acquisition and operating stages, the Fund may incur short term borrowing to fund regular distributions of such gross revenues to be generated by newly acquired transactions during their respective initial fixed terms. As such, all Fund periodic cash distributions made during these stages have been, and are expected in the future to be, based on the Fund’s actual and anticipated gross revenues to be generated from the binding initial terms of the leases and loans acquired.

The following table summarizes distribution activity for the Fund from inception through December 31, 2017 (in thousands except for Units and Per Unit Data):

In particular, economic recession and changes in general economic conditions, including fluctuations in demand for equipment, lease rates, and interest rates, may result in delays in investment and reinvestment, delays in leasing, re-leasing, and disposition of equipment, and reduced returns on invested capital. The Company’s performance is subject to risks relating to lessee defaults and the creditworthiness of its lessees. The Company’s performance is also subject to risks relating to the value of its equipment at the end of its leases, which may be affected by the condition of the equipment, technological obsolescence and the markets for new and used equipment at the end of lease terms. Investors are cautioned not to attribute undue certainty to these forward-looking statements, which speak only as of the date of this Form 10-K.

Overview

ATEL 15, LLC (the “Company” or the “Fund”) was formed under the laws of the state of California on March 4, 2011 (“Date of Inception”) for the purpose of equipment financing and acquiring equipment to engage in equipment leasing and sales activities.

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 4, 2012, at which time a request was processed to release the Pennsylvania escrowed amounts. The offering was terminated on October 28, 2013 with a total of 6,620,971 Units subscribed, representing contributions, net of rescissions and repurchases, approximating $66.0 million. As of December 31, 2017, 6,557,057 Units were issued and outstanding.

During 2012, the Company began its acquisition stage with the investment of the net proceeds from the public offering of Units. During the reinvestment period (“Reinvestment Period”) (defined as six full years following the year the offering was terminated), the Company has reinvested and will reinvest cash flow in excess of certain amounts required to be distributed to the members and/or utilize its credit facilities to acquire additional equipment. Throughout the Reinvestment Period, which ends December 31, 2019, the Company anticipates continued reinvestment of cash flow in excess of minimum distributions and other obligations. The Company is governed by its Limited Liability Company Operating Agreement dated October 28, 2011 (“Operating Agreement”).

The Company shall continue until terminated in accordance with the provisions of the Operating Agreement. Periodic distributions are paid at the discretion of the Managing Member.

Results of Operations

It is the Company’s objective to maintain a 100% utilization rate for all equipment purchased in any given year. All equipment transactions are acquired subject to binding lease commitments, so equipment utilization is expected to remain high during the funding period and throughout the reinvestment stage. Initial lease terms of these leases are generally from 36 to 120 months, and as they expire, the Company will attempt to re-lease or sell the equipment. All of the Company’s equipment on lease was purchased in the years 2011 through 2015. The utilization percentage of existing assets under lease was 86% and 87% at December 31, 2017 and 2016, respectively.

Cost reimbursements to the Managing Member and/or 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.

2017 versus 2016

The Company had net loss of $39 thousand and net income of $44 thousand for the years ended December 31, 2017 and 2016, respectively. The results for the year ended December 31, 2017 reflect decreases in both total revenues and total operating expenses when compared to the prior year period.

Revenues

Total revenues for the year ended December 31, 2017 declined by $2.0 million, or 21%, as compared to the prior year period. Such decrease was largely due to a $1.9 million, or 20%, reduction in operating lease revenues, mainly the result of portfolio runoff and dispositions of lease assets; a $237 thousand unfavorable decrease in the gain on sales or dispositions of investment in securities; a $124 thousand, or more than 2 times, unfavorable change in the gain/loss on the sale of lease assets and early termination of notes due to a change in the mix of assets sold; and a $115 thousand, or 84%, decrease in interest on notes receivables, due to a decrease in outstanding notes in the current year period; offset, in part, by a $377 thousand, or 99%, favorable change in the fair market value adjustment on warrant holdings.

Expenses

Total expenses for the year ended December 31, 2017 decreased by $1.9 million, or 20%, as compared to the prior year period. The net decrease in total expenses was primarily the result of a $1.9 million, or 29%, decrease in depreciation of operating lease assets, a result of lease portfolio run-off and sales of lease assets; a $112 thousand, or 28%, decrease in interest expense, a result of a $1.4 million net reduction in outstanding borrowings since December 31, 2016; a $101 thousand, or 104%, decrease in acquisition expense due to lower acquisition of operating lease assets; a $92 thousand, or 2 times, favorable turnaround in the provision for credit losses, a direct result of the collection of amounts previously reserved as uncollectible; and an $80 thousand, or 18%, decrease, in asset management fees to Managing Member, the result of lower asset balances under management and related revenues; offset, in part, by a $50 thousand, increase in impairment losses on investment in securities; a $186 thousand, or 131%, increase in professional fees, related to legal fees associated with a legal action against a lessee of the Company; a $129 thousand, or 15%, increase in cost reimbursement to the managing member and/or affiliates, the result of higher indirect cost allocations, a result of refinement of cost allocation methodology; and a $37 thousand, or 53%, increase in outside services, indicative of additional efforts required to comply with certain regulatory requirements.

Capital Resources and Liquidity

At December 31, 2017 and 2016, the Company’s cash and cash equivalents totaled $932 thousand and $2.6 million, respectively. The liquidity of the Company varies, increasing to the extent cash flows from leases and proceeds of asset sales exceed expenses and decreasing as distributions are made to the Members and to the extent expenses exceed cash flows from leases and proceeds from asset sales.

The Company currently believes it has adequate reserves available to meet its immediate cash requirements and those of the next twelve months, but in the event those reserves were found to be inadequate, the Company would likely be in a position to borrow against its current portfolio to meet such requirements.

Cash Flows

The following table sets forth summary cash flow data (in thousands):

		2017				2016
Net cash provided by (used in):
Operating activities		$	5,490			$	6,656

Financing activities			(7,890	)			(11,561	)
Net decrease in cash and cash equivalents		$	(1,645	)		$	(3,046	)

2017 versus 2016

During 2017 and 2016, the Company’s primary sources of liquidity were cash flows from its portfolio of operating and direct financing lease contracts, and its investments in notes receivable. In addition, the Company realized a total of $397 thousand and $565 thousand of proceeds from sales of lease assets and investments in securities during 2017 and 2016, respectively. The Company utilized borrowings from the credit facility of $2.3 million during 2017 to supplement its cash flow requirements. The Company received principal payments on notes receivable of $417 thousand and $1.3 million during 2017 and 2016, respectively.

During the same comparative years, cash was primarily used to pay distributions and repay debt. Distributions paid to both Other Members and the Managing Member totaled $6.4 million for both 2017 and 2016; while cash used to repay debt totaled $3.7 million and $5.0 million, respectively.

Revolving credit facility

As of December 31, 2017 and 2016, the Company had outstanding revolving credit balances totaling $2.3 million and $0, respectively. Effective May 25, 2012, the Company participates with AFS and certain of its affiliates in a revolving credit facility (the “Credit Facility”) with a syndicate of financial institutions. The Credit Facility is comprised of a working capital facility to AFS, an acquisition facility (the “Acquisition Facility”), Institutional Leasing Sub Facility, and a warehouse facility (the “Warehouse Facility”) to AFS, the Company and affiliates, and a venture facility available to an affiliate. As of December 31, 2017, the Credit Facility is for an amount up to $75.0 million and has been extended to June 30, 2019. The lending syndicate providing the Credit Facility has a blanket lien on all of the Company’s assets as collateral for any and all borrowings under the Acquisition Facility, and on a pro-rata basis under the Warehouse Facility. Such Credit Facility includes certain financial covenants.

Compliance with covenants

The Credit Facility includes certain financial and non-financial covenants applicable to each borrower, including the Company. Such covenants include covenants typically found in credit facilities of the size and nature of the Credit Facility, such as accuracy of representations, good standing, absence of liens and material litigation, etc. The Company was in compliance with all applicable covenants under the Credit Facility as of December 31, 2017. The Company considers certain financial covenants to be material to its ongoing use of the Credit Facility and these covenants are described below.

Material financial covenants

Under the Credit Facility, the Company is required to maintain a specific tangible net worth, to comply with a leverage ratio and an interest coverage ratio, and to comply with other terms expressed in the Credit Facility, including limitation on the incurrence of additional debt and guaranties, defaults, and delinquencies.

As of December 31, 2017, the material financial covenants are summarized as follows:

Minimum Tangible Net Worth: $10.0 million
Leverage Ratio (leverage to Tangible Net Worth): Not to exceed 1.25 to 1
Collateral Value: Collateral value under the Warehouse Facility must be no less than the outstanding borrowings under that facility
EBITDA to Interest Ratio: Not to be less than 2 to 1 for the four fiscal quarters just ended

“EBITDA” is defined under the Credit Facility as, for the relevant period of time (1) gross revenues (all payments from leases and notes receivable) for such period minus (2) expenses deducted in determining net income for such

12

period plus (3) to the extent deducted in determining net income for such period (a) provision for income taxes and (b) interest expense, and (c) depreciation, amortization and other non-cash charges. Extraordinary items and gains or losses on (and proceeds from) sales or dispositions of assets outside of the ordinary course of business are excluded in the calculation of EBITDA. “Tangible Net Worth” is defined as, as of the date of determination, (i) the net worth of the Company, after deducting there from (without duplication of deductions) the net book amount of all assets of the Company, after deducting any reserves and other amounts for assets which would be treated as intangibles under GAAP and after certain other adjustments permitted under the agreements.

The financial covenants referred to above are applicable to the Company only to the extent that the Company has borrowings outstanding under the Credit Facility. The Company was in compliance with these financial covenants under the Credit Facility with a minimum Tangible Net Worth, leverage ratio and (EBITDA) interest coverage ratio, as calculated per the Credit Facility agreement of $20.5 million, 0.44 to 1, and 18.76 to 1, respectively, as of December 31, 2017. As such, as of December 31, 2017, the Company was in compliance with all such material financial covenants.

Reconciliation to GAAP of EBITDA

For purposes of compliance with the Credit Facility covenants, the Company uses a financial calculation of EBITDA, as defined therein, which is a non-GAAP financial performance measure. The EBITDA is utilized by the Company to calculate its debt covenant ratios.

The following is a reconciliation of net loss to EBITDA, as defined in the loan agreement, for the twelve months ended December 31, 2017 (in thousands):

Net loss		$	(39	)
Interest expense			293
Depreciation and amortization			4,736
Amortization of initial direct costs			74
Impairment losses			11
Provision for credit losses			(44	)
Provision for losses on investment in securities			50
Unrealized loss on fair valuation of warrants			(3	)
Principal payments received on direct financing leases			1
Principal payments received on notes receivable			417
EBITDA (for Credit Facility financial covenant calculation only)		$	5,496

Events of default, cross-defaults, recourse and security

The terms of the Credit Facility include standard events of default by the Company which, if not cured within applicable grace periods, could give lenders remedies against the Company, including the acceleration of all outstanding borrowings and a demand for repayment in advance of their stated maturity. If a breach of any material term of the Credit Facility should occur, the lenders may, at their option, increase borrowing rates, accelerate the obligations in advance of their stated maturities, terminate the facility, and exercise rights of collection available to them under the express terms of the facility, or by operation of law. The lenders also retain the discretion to waive a violation of any covenant at the Company’s request.

The Company is currently in compliance with its obligations under the Credit Facility. In the event of a technical default (e.g., the failure to timely file a required report, or a one-time breach of a financial covenant), the Company believes it has ample time to request and be granted a waiver by the lenders, or, alternatively, cure the default under the existing provisions of its debt agreements, including, if necessary, arranging for additional capital from alternate sources to satisfy outstanding obligations.

The Acquisition Facility is generally recourse solely to the Company, and is not cross-defaulted to any other obligations of affiliated companies under the Credit Facility, except as described in this paragraph. The Credit Facility is cross-defaulted to a default in the payment of any debt (other than non-recourse debt) or any other agreement or condition beyond the period of grace (not exceeding 30 days), the effect of which would entitle the lender under such agreement to accelerate the obligations prior to their stated maturity in an individual or aggregate principal amount in excess of 15% of the Company’s consolidated Tangible Net Worth. Also, a bankruptcy of AFS will trigger a default for the Company under the Credit Facility.

13

Non-Recourse Long-Term Debt

As of December 31, 2017 and 2016, the Company had non-recourse long-term debt totaling $4.7 million and $8.3 million, respectively. Such non-recourse notes payable do not contain any material financial covenants. The notes are secured by a specific lien granted by the Company to the non-recourse lenders on (and only on) the discounted lease transactions. The lenders have recourse only to the following collateral: the leased equipment; the related lease chattel paper; the lease receivables; and proceeds of the foregoing items.

Senior Long-Term Debt

As of December 31, 2017 and 2016, the Company had senior long-term debt totaling $2.1 million. The debt was utilized to partially fund the marine vessel and related bareboat charter purchased by the Fund and its affiliate, ATEL 14, LLC. The full pro rata principal amount of $2.1 million plus all outstanding accrued and unpaid interest of approximately $400 thousand shall be paid in one payment of $2.5 million due on May 25, 2019. The note is recourse to the residual value of the vessel which is expected to be well in excess of the note amount. In addition, the lender has recourse to the Fund’s general assets up to $2.5 million. The note does not contain any material financial covenants and is guaranteed as a senior obligation by the Fund.

For detailed information on the Company’s debt obligations, see Notes 8 through 10 to the financial statements as set forth in Part II, Item 8, Financial Statements and Supplementary Data.

Distributions

The Company commenced periodic distributions beginning with the month of January 2012. Additional distributions have been consistently made through December 31, 2017. See Item 5, Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities, for additional information regarding the distributions.

Commitments and Contingencies and Off-Balance Sheet Transactions

Commitments and Contingencies

At December 31, 2017, there were no commitments to purchase lease assets or to fund investments in notes receivable.

Off-Balance Sheet Transactions

NOTES TO FINANCIAL STATEMENTS

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 (“Date of Inception”) for the purpose of equipment financing 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, LLC (“AFS”), a wholly-owned subsidiary of ATEL Capital Group. The Fund shall continue until terminated in accordance with the provisions of 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, 2017, cumulative gross contributions, less rescissions and repurchases (net of distributions paid and allocated syndication costs, as applicable), totaling $66.0 million (inclusive of the $500 initial Member’s capital investment) have been received. As of the same date, 6,557,057 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 calendar years after the completion of the Company’s public offering of Units) and (iii) provide additional cash distributions following the Reinvestment Period and until all investment portfolio assets has been sold or otherwise disposed. The Company is governed by the ATEL 15, LLC amended and restated Limited Liability Company Operating Agreement dated October 28, 2011 (the “Operating Agreement”).

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 7). 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.

2. Summary of significant accounting policies:

Basis of presentation:

The accompanying balance sheets as of December 31, 2017 and 2016, and the related statements of operations, 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, 2017, up until the issuance of the financial statements. No events were noted which would require additional disclosure in the footnotes to the financial statements, and adjustments thereto.

NOTES TO FINANCIAL STATEMENTS

2. Summary of significant accounting policies: - (continued)

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 and reserve for credit losses on notes receivable.

Accounts receivable:

Accounts receivable represent the amounts billed under operating and direct financing lease contracts, and notes receivable which are 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 borrowers, 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 and direct financing lease receivables, notes receivable 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 and notes receivable represent amounts due from lessees or borrowers in various industries, related to equipment on operating and direct financing leases or notes receivable.

Equipment on operating leases and related revenue recognition:

Equipment subject to operating leases is stated at cost. Depreciation is 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 ASC 840-20-35-3, 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.

Direct financing leases and related revenue recognition:

Income from direct financing lease transactions is reported using the financing method of accounting, in which the Company’s investment in the leased property is reported as a receivable from the lessee to be recovered through future rentals. The interest income portion of each rental payment is calculated so as to generate a constant rate of return on the net receivable outstanding.

Allowances for losses on direct financing leases are typically established based on historical charge-off and collection experience and the collectability of specifically identified lessees and billed and unbilled receivables. Direct financing leases are charged off to the allowance as they are deemed uncollectible.

Direct financing leases are generally placed in a non-accrual status (i.e., no revenue is recognized) and deemed impaired when payments are more than 90 days past due. Additionally, management periodically reviews the creditworthiness of all direct finance lessees with payments outstanding less than 90 days. Based upon management’s judgment, the related direct financing 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, all payments received are applied only against outstanding principal balances.

Notes receivable, unearned interest income and related revenue recognition:

The Company records all future payments of principal and interest on notes as notes receivable, which are then offset by the amount of any related unearned interest income. For financial statement purposes, the Company reports only the net amount of principal due on the balance sheet. The unearned interest is recognized over the term of the note and the income portion of each note payment is calculated so as to generate a constant rate of return on the net balance outstanding. Any fees or costs related to notes receivable are recorded as part of the net investment in notes receivable and amortized over the term of the loan.

Allowances for losses on notes receivable are typically established based on historical charge off and collection experience and the collectability of specifically identified borrowers and billed and unbilled receivables. Notes are considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal and/or interest when due according to the contractual terms of the note agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. If it is determined that a loan is impaired with regard to scheduled payments, the Company will perform an analysis of the note to determine if an impairment valuation reserve is necessary. This analysis considers the estimated cash flows from the note, or the collateral value of the property underlying the note when note repayment is collateral dependent. Any required valuation reserve is charged to earnings when determined; and notes are charged off to the allowance as they are deemed uncollectible.

Notes receivable 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 periodically reviews the creditworthiness of companies with note payments outstanding less than 90 days. Based upon management’s judgment, the related notes may be placed on non-accrual status. Notes 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 receivable is probable. Until such time, all payments received are applied only against outstanding principal balances.

Initial direct costs:

The Company capitalizes initial direct costs (“IDC”) associated with the origination and funding of lease assets and investments in notes receivable. IDC includes both internal costs (e.g., the costs of employees’ activities in connection with successful lease and loan originations) and external broker fees incurred with such originations. The costs are amortized on a lease by lease (or note by note) basis based on actual lease term using a straight-line method for operating leases and the effective interest rate method for direct financing leases and notes receivable. Upon disposal of the underlying lease assets and notes receivable, both the initial direct costs and the associated accumulated amortization are relieved. Costs related to leases or notes receivable that are not consummated are not eligible for capitalization as initial direct costs and are expensed as acquisition expense.

Acquisition expense:

Acquisition expense represents costs which include, but are not limited to, legal fees and expenses, travel and communication expenses, cost of appraisals, accounting fees and expenses and miscellaneous expenses related to the selection and acquisition of equipment which are reimbursable to the Managing Member under the terms of the Operating Agreement. As the costs are not eligible for capitalization as initial direct costs, such amounts 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 Company’s principal decision makers are the Managing Member’s Chief Executive Officer and its Chief Financial Officer and Chief Operating Officer. The Company believes that its equipment leasing business operates as one reportable segment because: a) the Company measures profit and loss at the equipment portfolio level as a whole; b) the principal decision makers do not review information based on any operating segment other than the equipment

leasing transaction portfolio; c) the Company does not maintain discrete financial information on any specific segment other than its equipment financing operations; d) the Company has not chosen to organize its business around different products and services other than equipment lease financing; and e) the Company has not chosen to organize its business around geographic areas.

The primary geographic region in which the Company seeks leasing opportunities is North America. As of and for the years ended December 31, 2017 and 2016, all of the Company’s current operating revenues and long-lived assets relate to customers domiciled in the United States.

Investment in securities:

Purchased securities

Purchased securities are generally not registered for public sale and are carried at cost. Such securities are adjusted to fair value if the fair value is less than the carrying value and such impairment is deemed by the Managing Member to be other than temporary. 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 $133 thousand and $183 thousand of purchased securities at December 31, 2017 and 2016, respectively. Based upon the Company’s review of its investment in securities portfolio, the Company recorded fair value adjustments on investment in securities totaling $50 thousand and $0 during 2017 and 2016, respectively. There was no gain on sales or dispositions of investment in securities in 2017. The Company realized $237 thousand of gains from sales or disposition of securities in 2016.

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. The Company recorded unrealized losses of $3 thousand and $380 thousand on fair valuation of its warrants during 2017 and 2016, respectively. The unrealized losses recorded during 2017 and 2016 reduced the estimated fair value of the Company’s portfolio of warrants to $387 thousand and $390 thousand at December 31, 2017 and 2016, respectively. The Company realized no gains or losses from the net exercise of warrants during 2017 and 2016.

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, 2017 and 2016, the related provision for state income taxes was approximately $7 thousand and $0 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.

Recent accounting pronouncements:

In August 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update2016-15 —  Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). ASU 2016-15 addresses specific cash flow issues with the objective of reducing the existing diversity in practice. The amendments in this Update are effective for fiscal years beginning after December 15,2017, and interim periods within those fiscal years. This guidance is effective for the Company beginning on January 1, 2018. The adoption of ASU 2016-15 did not have a material impact on its financial statements and disclosures.

In June 2016, the FASB issued Accounting Standards Update 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 net investment in leases that are not accounted for at fair value through net income. The amendments affect loans, debt securities, trade receivables, net investments in 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. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018. Management is currently evaluating the standard and expects the Update may potentially result in an increase in the allowance for credit losses given the change to estimated losses over the contractual life adjusted for expected prepayments.

2. Summary of significant accounting policies: - (continued)

In February 2016, the FASB issued Accounting Standards Update 2016-02, Leases (Topic 842) (“ASU 2016-02”). The new standard will require lessees to recognize lease assets and lease liabilities arising from operating leases with lease terms greater than 12 months in the statement of financial position. Lessor accounting per ASU 2016-02 is mostly unchanged from the previous lease accounting under GAAP. Certain changes were made to the lessor accounting guidance in order to align the lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers. Similar to the previous guidance, lessors will classify leases as operating, direct financing, or sales-type. Lessors in operating leases will continue to recognize the underlying asset and recognize income on a straight-line basis. Lessors determine whether a lease is a sale of the underlying asset based on whether the lessee effectively obtains control of the underlying assets. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. While early adoption is permitted, the Company does not expect to elect that option. The Company expects to adopt the guidance in the first quarter 2019 using the modified retrospective method.

Management is currently evaluating the impact of this standard on the financial statements and its operational and related disclosure requirements, including the impact on the Company’s current lease portfolio from a lessor perspective. Given the limited changes to lessor accounting, Management does not expect material changes to recognition or measurement, but the Company is early in the implementation process and will continue to evaluate the impact.

In January 2016, the FASB issued Accounting Standards Update 2016-01, Financial Instruments — Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). The new standard provides guidance related to accounting for equity investments and financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. ASU 2016-01, among other things, (i) requires equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income, (ii) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, (iii) eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet, (iv) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, and (v) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements. ASU 2016-01 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. This guidance is effective for the Company beginning on January 1, 2018. The adoption of ASU 2016-01 did not have a material impact on its financial statements and disclosures.

In May 2014, the FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which amends the existing accounting standards for revenue recognition. ASU 2014-09 is based on principles that govern the recognition of revenue at an amount an entity expects to be entitled when products are transferred to customers. On July 9, 2015, the FASB approved the deferral of the effective date of ASU 2014-09 by one year and in August 2015, issued Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date (“ASU 2015-14”). ASU 2015-14 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 31, 2016, including interim reporting periods within that reporting period. The new revenue standard may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption. This guidance is effective for the Company beginning on January 1, 2018. Management’s evaluation of the impact of such adoption on the financial statements of the Fund indicates that such impact is non-material as the new revenue guideline does not affect revenues from leases and loans, which comprise the majority of the Company’s revenues.

3. 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 and notes receivable provide for the return of the equipment to the Company upon default.

As of December 31, 2017 and 2016, 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		2017				2016
Oil/Gas extraction			35	%			32	%
Manufacturing			20	%			19	%

During 2017 and 2016, 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:

Lessee		Type of Equipment				Percentage of Total Leasing and Lending Revenues
						2017				2016
Halliburton Overseas Limited			Marine vessel				34%				27%
Cargill, Inc.			Materials handling				12%				10%
GE Aviation			Manufacturing				12%				*
Signature Brands, LLC			Food processing				12%				10%
The Kansas City Southern Railway Company			Transportation, rail				11%				*

These percentages are not expected to be comparable in future periods due to anticipated changes in the mix of investments and/or lessees as a result of normal business activities.

4. Notes receivable, net:

The Company has various notes receivable from borrowers who have financed the purchase of equipment through the Company. As of December 31, 2017, the terms of the notes are from 9 to 90 months with interest ranging from 4.15% to 18.00% per annum. The notes are secured by the equipment financed and have maturity dates in 2018 and 2020.

6. Allowance for credit losses: - (continued)

As of December 31, 2017 and 2016, the Company’s allowance for credit losses (related solely to financing receivables) and its recorded investment in financing receivables were as follows (in thousands):

The Company evaluates the credit quality of its financing receivables on a scale equivalent to the following quality indicators related to corporate risk profiles:

Pass — Any account whose lessee/debtor, co-lessee/debtor or any guarantor has a credit rating on publicly traded or privately placed debt issues as rated by Moody’s or S&P for either Senior Unsecured debt, Long Term Issuer rating or Issuer rating that are in the tiers of ratings generally recognized by the investment community as constituting an Investment Grade credit rating; or, has been determined by the Manager to be an Investment Grade Equivalent or High Quality Corporate Credit per its Credit Policy or has a Not Rated internal rating by the Manager and the account is not considered by the Chief Credit Officer of the manager to fall into one of the three risk profiles below.

Special Mention — Any traditional corporate type account with potential weaknesses (e.g. large net losses or major industry downturns) or, any growth capital account that has less than three months of cash as of the end of the calendar quarter to fund their continuing operations. These accounts deserve management’s close attention. If left uncorrected, those potential weaknesses may result in deterioration of the Fund’s receivable at some future date.

Substandard — Any account that is inadequately protected by the current worth and paying capacity of the borrower or of the collateral pledged, if any. Accounts that are so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Fund will sustain some loss as the likelihood of fully collecting all receivables may be questionable if the deficiencies are not corrected. Such accounts are on the Manager’s Credit Watch List.

Doubtful — Any account where the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Accordingly, an account that is so classified is on the Manager’s Credit Watch List, and has been declared in default and the Manager has repossessed, or is attempting to repossess, the equipment it financed. This category includes impaired notes and leases as applicable.

7. 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”) is a wholly-owned subsidiary of ATEL Capital Group, Inc. and performs 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, 2017 and 2016 as follows (in thousands):

		2017				2016
Administrative costs reimbursed to Managing Member and/or affiliates		$	1,000			$	871
Asset management fees to Managing Member			360				440
Acquisition and initial direct costs paid to Managing Member			6				97
		$	1,366			$	1,408

8. Non-recourse debt:

At December 31, 2017, non-recourse debt consists of notes payable to financial institutions. The notes are due in monthly installments. Interest on the notes is at fixed rates ranging from 2.64% to 3.66% per annum. The notes are secured by assignments of lease payments and pledges of assets. At December 31, 2017, gross operating lease rentals totaled approximately $4.8 million over the remaining lease terms; and the carrying value of the pledged assets is $15.8 million. The notes mature at various dates from 2018 through 2020.

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.

9. Senior long-term debt:

As of December 31, 2017, the $2.1 million of senior long-term debt consists of a note payable to a lender. Such debt was utilized during the fourth quarter of 2013 to partially fund the marine vessel and related bareboat charter purchased by the Fund and its affiliate, ATEL 14, LLC. The note bears interest at a fixed-rate of 3.5% per annum, to accrue in arrears on a monthly basis. The full pro rata principal amount of $2.1 million plus all outstanding accrued and unpaid interest of approximately $400 thousand shall be paid in one payment of $2.5 million due on May 25, 2019. The note is recourse to the residual value of the vessel which is expected to be well in excess of the note amount. In addition, the lender has recourse to the Fund’s general assets up to $2.5 million. The note does not contain any material financial covenants and is guaranteed as a senior obligation by the Fund.

10. Borrowing facilities:

Effective May 25, 2012, the Company participates with AFS and certain of its affiliates in a revolving credit facility (the “Credit Facility”) with a syndicate of financial institutions as lenders. The Credit Facility is comprised of a working capital facility to AFS, an acquisition facility (the “Acquisition Facility”), Institutional Leasing Sub Facility, and a warehouse facility (the “Warehouse Facility”) to AFS, the Company and affiliates, and a venture facility available to an affiliate. As of December 31, 2017, the Credit Facility is for an amount of $75.0 million and has been extended to June 30, 2019. The lending syndicate providing the Credit Facility has a blanket lien on all of the Company’s assets as collateral for any and all borrowings under the Acquisition Facility, and on a pro-rata basis under the Warehouse Facility. Such Credit Facility includes certain financial covenants.

As of December 31, 2017 and 2016, borrowings under the Credit Facility were as follows (in thousands):

		2017				2016
Total available under the financing arrangement		$	75,000			$	75,000
Amount borrowed by the Company under the acquisition facility			(2,250	)			—
Amounts borrowed by affiliated partnerships and limited liability companies under the working capital, acquisition and warehouse facilities			(3,520	)			(1,030	)
Amounts borrowed by institutional leasing trust under institutional line			—				(8,488	)
Total remaining available under the working capital, acquisition and warehouse facilities		$	69,230			$	65,482

The Company and its affiliates pay an annual commitment fee to have access to this line of credit. As of December 31, 2017, the aggregate amount of the Credit Facility is potentially available to the Company, subject to certain sub-facility and borrowing-base limitations. However, as amounts are drawn on the Credit Facility by each of the Company and the affiliates who are borrowers under the Credit Facility, the amount remaining available to all borrowers to draw under Credit Facility is reduced. As the Warehousing Facility is a short term bridge facility, any amounts borrowed under the Warehousing Facility, and then repaid by the affiliated borrowers (including the Company) upon allocation of an acquisition to a specific purchaser, become available under the Warehouse Facility for further short term borrowing.

10. Borrowing facilities: - (continued)

As of December 31, 2017, the Company’s Tangible Net Worth requirement under the Credit Facility was $10.0 million, the permitted maximum leverage ratio was not to exceed 1.25 to 1, and the required minimum interest coverage ratio was not to be less than 2 to 1. The Company was in compliance with these financial covenants under the Credit Facility with a minimum Tangible Net Worth, leverage ratio and interest coverage ratio, as calculated per the Credit Facility agreement of $20.5 million, 0.44 to 1 and 18.76 to 1, respectively, as of December 31, 2017. As such, as of December 31, 2017, the Company was in compliance with all material financial covenants, and with all other material conditions of the Credit Facility. The Company does not anticipate any covenant violations nor does it anticipate that any of these covenants will restrict its operations or its ability to procure additional financing.

Fee and interest terms

The interest rate on the Credit Facility is based on either the LIBOR/Eurocurrency rate of 1-, 2-, 3- or 6-month maturity plus a lender designated spread, or the bank’s Prime rate, which re-prices daily. Principal amounts of loans made under the Credit Facility that are prepaid may be re-borrowed on the terms and subject to the conditions set forth under the Credit Facility. As of December 31, 2017, the Company had borrowings totaling $2.3 million with an effective interest rates ranging from 3.72% to 3.82%. During both the year ended December 31, 2017, the weighted average interest rate on borrowings was 3.62%. There were no borrowings during 2016.

Warehouse facility

To hold the assets under the Warehousing Facility prior to allocation to specific investor programs, a Warehousing Trust has been entered into by the Company, AFS, ALC, and certain of the affiliated partnerships and limited liability companies. The Warehousing Trust is used by the Warehouse Facility borrowers to acquire and hold, on a short-term basis, certain lease transactions that meet the investment objectives of each of such entities. Each of the leasing programs sponsored by AFS and ALC is a pro rata participant in the Warehousing Trust, as described below. When a program no longer has a need for short-term financing provided by the Warehousing Facility, it is removed from participation, and as new leasing investment entities are formed by AFS and ALC and commence their acquisition stages, these new entities are added.

As of December 31, 2017, the investment program participants were the Company, ATEL 14, LLC, ATEL 16, LLC and ATEL 17, LLC. Pursuant to the Warehousing Trust, the benefit of the lease transaction assets, and the corresponding liabilities under the Warehouse Facility, inure to each of such entities based upon each entity’s pro-rata share in the Warehousing Trust estate. The “pro-rata share” is calculated as a ratio of the net worth of each entity over the aggregate net worth of all entities benefiting from the Warehousing Trust estate, excepting that the trustees, AFS and ALC, are both jointly and severally liable for the pro-rata portion of the obligations of each of the affiliated limited liability companies participating under the Warehouse Facility. Transactions are financed through this Warehouse Facility only until the transactions are allocated to a specific program for purchase or are otherwise disposed by AFS and ALC. When a determination is made to allocate the transaction to a specific program for purchase by the program, the purchaser repays the debt associated with the asset, either with cash or by means of proceeds of a draw under the Acquisition Facility, and the asset is removed from the Warehouse Facility collateral, and ownership of the asset and any debt obligation associated with the asset are assumed solely by the purchasing entity.

The Company borrowed $2.3 million and $0 under the Acquisition Facility as of December 31, 2017 and 2016, respectively.

11. Commitments:

At December 31, 2017, there were no commitments to purchase lease assets or to fund investments in notes receivable.

ATEL 15, LLC
 
NOTES TO FINANCIAL STATEMENTS

12. Guarantees:

The Company enters into contracts that contain a variety of indemnifications. The Company’s maximum exposure under these arrangements is unknown. 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.

13. Members’ capital:

A total of 6,557,057 Units and 6,584,221 Units were issued and outstanding at December 31, 2017 and 2016, respectively, including the 50 Units issued to the initial Member (Managing Member). 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.

Distributions to the Other Members for the years ended December 31, 2017 and 2016 were as follows (in thousands except Units and per Unit data):

		2017				2016
Distributions declared		$	5,891			$	5,927
Weighted average number of Units outstanding			6,564,381				6,606,315
Weighted average distributions per Unit		$	0.90			$	0.90

14. Fair value measurements:

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.

36

ATEL 15, LLC
 
NOTES TO FINANCIAL STATEMENTS

14. Fair value measurements: - (continued)

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.

At December 31, 2017 and 2016, only the Company’s warrants were measured on a recurring basis. During the same comparative years, the Company recorded non-recurring adjustments to reduce the cost basis of certain assets deemed impaired. Such non-recurring adjustments reduced the cost basis of off lease equipment and notes receivable during 2017 and 2016, respectively.

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.

Such fair value adjustments utilized the following methodology:

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). As of December 31, 2017 and 2016, the calculated fair value of the Fund’s warrant portfolio approximated $387 thousand and $390 thousand, respectively. Such valuations are classified within Level 3 of the valuation hierarchy.

The following table reconciles the beginning and ending balances of the Company’s Level 3 recurring assets (in thousands):

		2017				2016
Fair value of warrants at beginning of year		$	390			$	770
Unrealized loss on fair valuation of warrants			(3	)			(380	)
Fair value of warrants at end of year		$	387			$	390

Impaired notes receivable (non-recurring)

The fair value of the Company’s notes receivable, when impairment adjustments are required, is estimated using either third party appraisals or estimations of the value of collateral (for collateral dependent loans).

During the year ended December 31, 2017, and 2016 the Company had recorded $0 and $5 thousand, respectively, of fair value adjustments relative to two impaired notes.

Impaired investment securities (non-recurring)

The Company’s investment securities are not registered for public sale and are carried at cost. The investment securities are adjusted for impairment, if any, based upon factors which 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.

During 2017 and 2016, the Company recorded a fair value adjustment of $50 thousand and $0 to reduce the cost basis of an impaired investment security, respectively. The reduction in value was based on a market approach technique and uses inputs that reflect qualitative and quantitative information provided by the management of the investee. Such information indicated reduced growth opportunity and eventual reduction in cash flows and revenues. Under the Fair Value Measurements Topic of the FASB Accounting Standards Codification, the fair value of the aforementioned impaired investment securities were classified within Level 3 of the valuation hierarchy.

Impaired off-lease equipment (non-recurring)

During the year ended December 31, 2017 and 2016, the Company recorded fair value adjustments totaling $11 thousand and $0, respectively, to reduce the cost basis of certain-off lease equipment deemed impaired. The fair value adjustment recorded during the year ended December 31, 2017 was non-recurring and consisted of materials handling equipment. The impaired asset was subsequently sold during 2017.

Under the Fair Value Measurements Topic of the FASB Accounting Standards Codification, the fair value of the impaired lease assets were classified within Level 3 of the valuation hierarchy as the data source 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 table presents the fair value measurement of impaired assets measured at fair value on a non-recurring basis and the level within the hierarchy in which the fair value measurements fall at December 31, 2016 (in thousands):

		December 31, 2016				Level 1 Estimated Fair Value				Level 2 Estimated Fair Value				Level 3 Estimated Fair Value

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.

Notes receivable

The fair value of the Company’s notes receivable is generally estimated based upon various methodologies deployed by financial and credit management including, but not limited to, credit analysis, third party appraisal and/or discounted cash flow analysis based upon current market valuation techniques and market rates for similar types of lending arrangements, which may consider adjustments for impaired loans as deemed necessary.

Investment in securities

The Company’s investment securities are not registered for public sale and are carried at cost which management believes approximates fair value, as appropriately adjusted for impairment.

Credit facility

The credit facility includes the outstanding amounts on the Company’s credit facility. The carrying amount of these variable rate obligations approximate fair value based on current borrowing rates for similar types of borrowings.

Non-recourse and Senior long-term debt

The fair value of the Company’s non-recourse and long-term 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.

The following tables present estimated fair values of the Company’s financial instruments in accordance with the guidance provided by the Financial Instruments Topic of the FASB Accounting Standards Codification at December 31, 2017 and 2016 (in thousands):

15. Subsequent event:

On April 20, 2017 the Company, along with certain affiliates, was served a suit by a lessee of the Company in an action for declaratory relief to determine the fair market value of the leased equipment at the end of the initial lease term, December 31, 2016. The Company and its affiliates counter-claimed for a determination of the fair market value, and for holdover rent. The Company and the lessee entered into a Settlement Agreement that provided for an independent third-party appraisal process to determine the fair market value of the leased equipment at the end of the initial lease term, which determination was binding on the parties.

In January 2018, the Company prevailed in all of its claims and the settlement amount of $3.9 million was in excess of the net book value of the equipment of $2.1 million. The Company recorded a gain on the sale of assets of $1.8 million.

None.

Evaluation of disclosure controls and procedures

The Company’s Managing Member’s Chief Executive Officer, and Executive Vice President and Chief Financial and Operating Officer (“Management”), evaluated the effectiveness of the Company’s disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e)) as of the end of the period covered by this report. Based on the evaluation of the Company’s disclosure controls and procedures, the Chief Executive Officer and Executive Vice President and Chief Financial and Operating Officer concluded that as of the end of the period covered by this report, the design and operation of these disclosure controls and procedures were effective.

The Company does not control the financial reporting process, and is solely dependent on the Management of the Managing Member, who is responsible for providing the Company with financial statements in accordance with generally accepted accounting principles in the United States. The Managing Member’s disclosure controls and procedures, as they are applicable to the Company, means controls and other procedures of an issuer that are designed to ensure that information required to be disclosed by the issuer in the reports that it files or submits under the Act (15 U.S.C. 78a et seq.) is recorded, processed, summarized and reported, within the time periods specified in the Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Act is accumulated and communicated to the issuer’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Management’s Annual Report on Internal Control over Financial Reporting

The Management of the Managing Member is responsible for establishing and maintaining adequate internal control over financial reporting as that term is defined in Exchange Act Rule 13a-15(f) for the Company, and for performing an assessment of the effectiveness of internal control over financial reporting as of December 31, 2017. The internal control process of the Managing Member, as it is applicable to the Company, was designed to provide reasonable assurance to Management regarding the preparation and fair presentation of published financial statements, and includes those policies and procedures that:

All internal control processes, no matter how well designed, have inherent limitations. Therefore, even those processes determined to be effective can provide only reasonable assurance with respect to the reliability of financial statement preparation and presentation. Further, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.

Management of the Managing Member assessed the effectiveness of its internal control over financial reporting, as it is applicable to the Company, as of December 31, 2017. In making this assessment, it used the criteria set forth in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on its assessment, Management of the Managing Member concluded that the Managing Member’s internal control over financial reporting, as it is applicable to the Company, was effective as of December 31, 2017.

41

This annual report does not include an audit report of the Company’s independent registered public accounting firm regarding internal control over financial reporting. Management’s internal control over financial reporting was not subject to audit by the Company’s independent registered public accounting firm pursuant to Section 989G of the Dodd-Frank Wall Street Reform and Consumer Protection Act, which exempts non-accelerated filers from Section 404(b) of the Sarbanes-Oxley Act of 2002.

Changes in internal control

There were no changes in the Managing Member’s internal control over financial reporting, as it is applicable to the Company, during the year ended December 31, 2017 that has materially affected, or is reasonably likely to materially affect, the Managing Member’s internal control over financial reporting, as it is applicable to the Company.

Section 16(a) Beneficial Ownership Reporting Compliance

Based solely on a review of Forms 3, 4, and 5, the Company is not aware of any failures to file reports of beneficial ownership required to be filed during or for the year ended December 31, 2017.

Code of Ethics

A Code of Ethics that is applicable to the Company, including the Chief Executive Officer and Chief Financial Officer and Chief Operating Officer of its Manager, ATEL Managing Member, LLC, or persons acting in such capacity on behalf of the Company, is included as Exhibit 14.1 to this report.

Item 11. EXECUTIVE COMPENSATION

The registrant has no officers or directors.

Set forth hereinafter is a description of the nature of remuneration paid and to be paid to the Manager and its affiliates. The amount of such remuneration paid for the years ended December 31, 2017 and 2016 is set forth in Item 8 of this report under the caption “Financial Statements and Supplementary Data — Notes to Financial Statements — Related party transactions,” at Note 7 thereof, which information is hereby incorporated by reference.

Asset Management Fee and Carried Interest

The Company pays the Manager an annual Asset Management Fee in an amount equal to 4% of Gross Operating Lease Revenues and Cash from Sales or Refinancing. The Asset Management Fee is paid on a monthly basis. The amount of the Asset Management Fee payable in any year is reduced for that year to the extent it would otherwise exceed the Asset Management Fee Limit, as described below. The Asset Management Fee is paid for services rendered by the Manager and its affiliates in determining portfolio and investment strategies and generally managing or supervising the management of the investment portfolio.

The Manager supervises performance of all management activities, including, among other activities: the acquisition and financing of the investment portfolio, collection of lease and loan revenues, monitoring compliance by lessees borrowers with their contract terms, assuring that investment assets are being used in accordance with all operative contractual arrangements, paying operating expenses and arranging for necessary maintenance and repair of equipment and property in the event a lessee fails to do so, monitoring property, sales and use tax compliance and preparation of operating financial data. The Manager intends to delegate all or a portion of its duties and the Asset Management Fee to one or more of its affiliates who are in the business of providing such services.

The Manager also receives, as its Carried Interest, an amount equal to 7.5% of all Company Distributions.

Limitations on Fees

The Fund has adopted a single Asset Management Fee plus the Carried Interest as a means of compensating the Manager for sponsoring the Fund and managing its operations. While this compensation structure is intended to simplify management compensation for purposes of investor’s understanding, state securities administrators use a more complicated compensation structure in their review of equipment program offerings in order to assure that those offerings are fair under the states’ merit review guidelines. The total of all Front End Fees, the Carried Interest and the Asset Management Fee will be subject to the Asset Management Fee Limit in order to assure these state administrators that the Fund will not bear greater fees than permitted under the state merit review guidelines. The North American Securities Administrators Association, Inc. (“NASAA”) is an organization of state securities administrators, those state government agencies responsible for qualifying securities offerings in their respective states. NASAA has established

44

standards for the qualification of a number of different types of securities offerings and investment products, including its Statement of Policy on Equipment Programs (the “NASAA Equipment Leasing Guidelines”). Article IV, Sections C through G of the NASAA Equipment Leasing Guidelines establish the standards for payment of reasonable carried interests, promotional interests and fees for equipment acquisition, management, resale and releasing services to equipment leasing program sponsors. Article IV, Sections C through G of the NASAA Equipment Leasing Guidelines set the maximum compensation payable to the sponsor and its affiliates from an equipment leasing program such as the Fund. The Asset Management Fee Limit will equal the maximum compensation payable under Article IV, Sections C through G of the NASAA Equipment Leasing Guidelines as in effect on the date of the Fund’s prospectus (the “NASAA Fee Limitation”). Under the Asset Management Fee Limit, the Fund will calculate the maximum fees payable under the NASAA Fee Limitation and guarantee that the Asset Management Fee it will pay the Manager and its Affiliates, when added to its Carried Interest, will never exceed the fees and interest payable to a sponsor and its affiliates under the NASAA Fee Limitation.

Asset Management Fee Limit.  The Asset Management Fee Limit will be calculated each year during the Fund’s term by calculating the total fees that would be paid to the Manager if the Manager were to be compensated on the basis of the maximum compensation payable under the NASAA Fee Limitation, including the Manager’s Carried Interest, as described below. To the extent that the amount paid as Front End Fees, the Asset Management Fee, and the Carried Interest for any year would cause the total fees to exceed the aggregate amount of fees calculated under the NASAA Fee Limitation for the year, the Asset Management Fee and/or Carried Interest for that year will be reduced to equal the maximum aggregate fees under the NASAA Fee Limitation. To the extent any such fees are reduced, the amount of such reduction will be accrued and deferred, and such accrued and deferred compensation would be paid to the Manager in a subsequent period, but only to the extent that the deferred compensation would be within the Asset Management Fee Limit for that later period. Any deferred fees that cannot be paid under the applicable limitations through the date of liquidation would be forfeited by the Manager at liquidation.

Under the NASAA Equipment Leasing Guidelines, the Fund is required to commit a minimum percentage of the Gross Proceeds to Investment in Equipment, calculated as the greater of: (i) 80% of the Gross Proceeds reduced by 0.0625% for each 1% of indebtedness encumbering the Fund’s equipment; or (ii) 75% of such Gross Proceeds. The Fund intends to incur total indebtedness equal to 50% of the aggregate cost of its equipment. The Operating Agreement requires the Fund to commit at least 85.875% of the Gross Proceeds to Investment in Equipment. Based on the formula in the NASAA Guidelines, the Fund’s minimum Investment in Equipment would equal 76.875% of Gross Proceeds (80%-[50% × .0625%] = 76.875%), and the Fund’s minimum Investment in Equipment would therefore exceed the NASAA Fee Limitation minimum by 9%.

The amount of the Carried Interest permitted the Manager under the NASAA Fee Limitation will be dependent on the amount by which the percentage of Gross Proceeds the Fund ultimately commits to Investment in Equipment exceeds the minimum Investment in Equipment under the NASAA Fee Limitation. The NASAA Fee Limitation permits the Manager and its Affiliates to receive compensation in the form of a carried interest in Fund Net Income, Net Loss and Distributions equal to 1% for the first 2.5% of excess Investment in Equipment over the NASAA Guidelines minimum, 1% for the next 2% of such excess, and 1% for each additional 1% of excess Investment in Equipment. With a minimum Investment in Equipment of 85.875%, the Manager and its Affiliates may receive an additional carried interest equal to 6.5% of Net Profit, Net Loss and Distributions under the foregoing formula (2.5% + 2% + 4.5% = 9%; 1% + 1% + 4.5% = 6.5%). At the lowest permitted level of Investment in Equipment, the NASAA Guidelines would permit the Manager and its Affiliates to receive a promotional interest equal to 5% of Distributions of Cash from Operations and 1% of Distributions of Sale or Refinancing Proceeds until Members have received total Distributions equal to their Original Invested Capital plus an 8% per annum cumulative return on their Adjusted Invested Capital, and, thereafter, the promotional interest may increase to 15% of all Distributions.

With the additional carried interest calculated as described above, the maximum aggregate fees payable to the Manager and Affiliates under the NASAA Guidelines as carried interest and promotional interest would equal 11.5% of Distributions of Cash from Operations (6.5% + 5% = 11.5%), and 7.5% of Distributions of Sale or Refinancing Proceeds (6.5% + 1% = 7.5%), before the subordination level was reached, and 21.5% of all Distributions thereafter. The maximum amounts to be paid under the terms of the Operating Agreement are subject to the application of the Asset Management Fee Limit provided in Section 8.3 of the Agreement, which limits the annual amount payable to the Manager and its Affiliates as the Asset Management Fee and the Carried Interest to an aggregate not to exceed the total amount of fees that would be payable to the Manager and its Affiliates under the NASAA Fee Limitation.

Upon completion of the offering of Units, final commitment of offering proceeds to acquisition of equipment and establishment of final levels of permanent portfolio debt, the Manager will calculate the maximum carried interest and promotional interest payable to the Manager and its Affiliates under the NASAA Fee Limitation and compare such total permitted fees to the total of the Asset Management Fee and Manager’s Carried Interest. If and to the extent that the

45

Asset Management Fee and Manager’s Carried Interest would exceed the fees calculated under the NASAA Fee Limitation, the fees payable to the Manager and its Affiliates will be reduced by an amount sufficient to cause the total of such compensation to comply with the NASAA Fee Limitation. The adjusted Asset Management Fee Limit will then be applied to the Asset Management Fee and Carried Interest as described above. A comparison of the Front End Fees actually paid by the Fund and the NASAA Fee Limitation maximums will be repeated, and any required adjustments will be made, at least annually thereafter.

See Note 7 to the financial statements as set forth in Part II, Item 8, Financial Statements and Supplementary Data, for amounts paid.
