Organization and Limited Liability Company Matters [Abstract]

Organization and Limited Liability Company Matters

1. Organization and Limited Liability Company matters:

ATEL Capital Equipment Fund VIII, LLC (the “Company” or the “Fund”) was formed under the laws of the State of California on July 31, 1998. The Company was formed for the purpose of acquiring equipment to engage in equipment leasing and sales activities. The Managing Member or Manager of the Company is ATEL Financial Services, LLC (“AFS”), a California limited liability company. The Company may continue until December 31, 2019. Each Member’s personal liability for obligations of the Company generally will be limited to the amount of their respective contributions and rights to undistributed profits and assets of the Company.

The Company conducted a public offering of 15,000,000 Limited Liability Company Units (“Units”), at a price of $10 per Unit. On January 13, 1999, subscriptions for the minimum number of Units (120,000, representing $1.2 million) had been received (excluding subscriptions from Pennsylvania investors) and AFS requested that the subscriptions be released to the Company. On that date the Company commenced operations in its primary business. Gross contributions in the amount of $135.7 million (13,570,188 units) were received as of November 30, 2000, inclusive of $500 of initial Member’s capital investment and $100 of AFS’ capital investment. The offering was terminated on November 30, 2000. As of June 30, 2013, 13,560,188 Units remain issued and outstanding.

The Company’s principal objectives have been to invest in a diversified portfolio of equipment that (i) preserves, protects and returns the Company’s invested capital; (ii) generates regular distributions to the Members of cash from operations and cash from sales or refinancing, with any balance remaining after certain minimum distributions to be used to purchase additional equipment during the reinvestment period (“Reinvestment Period”) (defined as six full years following the year the offering was terminated), which ended December 31, 2006, and (iii) provides additional distributions following the Reinvestment Period and until all equipment has been sold. The Company is governed by its Limited Liability Company Operating Agreement (“Operating Agreement”), as amended.

Pursuant to the Operating Agreement, AFS and/or its affiliates receive compensation for services rendered and reimbursements for costs incurred on behalf of the Company (See Note 5). The Company is required to maintain reasonable cash reserves for working capital, the repurchase of Units and contingencies. The repurchase of Units is solely at the discretion of AFS.

As of June 30, 2013, the Company continues in the liquidation phase of its life cycle as defined in the Operating Agreement.

These unaudited interim financial statements should be read in conjunction with the financial statements and notes thereto contained in the report on Form 10-K for the year ended December 31, 2012, filed with the Securities and Exchange Commission.

Managing Member, events that have occurred after June 30, 2013, up until the issuance of the financial statements. No events were noted which would require disclosure in the footnotes to the financial statements, or adjustments thereto.

Use of estimates:

The preparation of 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 those estimates. Such estimates relate primarily to the determination of residual values at the end of the lease term and expected future cash flows used for impairment analysis purposes and determination of the allowance for doubtful accounts.

Segment reporting:

The Company is not organized by multiple operating segments for the purpose of making operating decisions or assessing performance. Accordingly, the Company operates in one reportable operating segment in the United States.

Certain of the Company’s lessee customers have international operations. In these instances, the Company is aware that certain equipment, primarily rail and transportation, may periodically exit the country. However, these lessee customers are US-based, and it is impractical for the Company to track, on an asset-by-asset, day-by-day basis, where these assets are deployed.

The primary geographic region in which the Company sought leasing opportunities was North America. The table below summarizes geographic information relating to the sources, by nation, of the Company’s total revenues for thesix months ended June 30, 2013 and 2012 and long-lived tangible assets as of June 30, 2013 and December 31, 2012 (dollars in thousands):

Gain Contingencies

7. Gain contingencies:

ATEL filed a claim on behalf of the Company and certain affiliated entities in Federal court in New Orleans for the under-reporting of revenue by a fleet manager of three marine vessels, seeking to recover an approximate amount of 10% of gross proceeds, which in the aggregate for all affiliated entities represents $2.8 million for the years 2005-2007 (of which the Company’s portion is an approximate $350 thousand). The annual allocable portion of the claim is not considered material to the Company in any given year. The trial was concluded during the first week of August 2012. In October 2012, the matter was remitted to the Federal Judge to render a decision on both the law and the facts. The decision of the Court was rendered at the end of June 2013 and the court found in favor of the defendants. The Company filed an appeal of the court’s decision and is hopeful for a recovery of all or portion of its asserted claims, but the outcome of the litigation remains uncertain as of such date.As a result of the ruling, the defendants have filed a claim for legal fees and costs, of which the Company’s portion would amount to approximately $88 thousand, however, this claim remains in dispute pending the outcome of the appeal, and a final award in favor of either party remains uncertain at this time.

Guarantees

6. 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.

Summary of Significant Accounting Policies [Abstract]

Basis of Presentation

Basis of presentation:

The accompanying unaudited financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q as mandated by the Securities and Exchange Commission. The unaudited interim financial statements reflect all adjustments which are, in the opinion of the Managing Member, necessary for a fair statement of financial position and results of operations for the interim periods presented. All such adjustments are of a normal recurring nature. Operating results for the three and six months ended June 30, 2013 are not necessarily indicative of the results to be expected for the full year.

Certain prior period amounts have been reclassified to conform to the current period presentation.These reclassifications had no significant effect on the reported financial position or results of operations.

Footnote and tabular amounts are presented in thousands, except as to Units and per Unit data.

Managing Member, events that have occurred after June 30, 2013, up until the issuance of the financial statements. No events were noted which would require disclosure in the footnotes to the financial statements, or adjustments thereto.

Use of Estimates

Use of estimates:

The preparation of 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 those estimates. Such estimates relate primarily to the determination of residual values at the end of the lease term and expected future cash flows used for impairment analysis purposes and determination of the allowance for doubtful accounts.

Segment Reporting

Segment reporting:

The Company is not organized by multiple operating segments for the purpose of making operating decisions or assessing performance. Accordingly, the Company operates in one reportable operating segment in the United States.

Certain of the Company’s lessee customers have international operations. In these instances, the Company is aware that certain equipment, primarily rail and transportation, may periodically exit the country. However, these lessee customers are US-based, and it is impractical for the Company to track, on an asset-by-asset, day-by-day basis, where these assets are deployed.

Related Party Transactions

5. Related party transactions:

The terms of the Operating Agreement provide that AFS 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 AFS for providing administrative services to the Company. Administrative services provided include Company accounting, investor relations, legal counsel and lease and equipment documentation. AFS is not reimbursed for services whereby it is entitled to receive a separate fee as compensation for such services, such as management of equipment.

5. Related party transactions (continued):

Each of ATEL Leasing Corporation (“ALC”) and AFS is a wholly-owned subsidiary of ATEL Capital Groupand 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 are based on its costs incurred in performing administrative services for the Company. These costs are allocated among all managed entities based on certain criteria such as managed assets, number of investors or contributed capital based upon the type of cost incurred.

During the three and six months ended June 30, 2013 and 2012, AFS and/or affiliates earned fees and commissions, and billed for reimbursements, pursuant to the Operating Agreement as follows (in thousands):

		Three Months Ended				Six Months Ended
		June 30,				June 30,
		2013		2012		2013		2012
Asset management fees to Managing Member	$	29	$	40	$	61	$	89
Cost reimbursements to Managing Member		72		73		152		289
	$	101	$	113	$	213	$	378

The Fund’s Operating Agreement places an annual and cumulative limit for cost reimbursements to AFS and/or its affiliates. Any reimbursable costs incurred by AFS and/or affiliates during the year exceeding the annual and/or cumulative limits cannot be reimbursed in the current year, though such costs may be reimbursable in future years to the extent such amounts may be payable if within the annual and cumulative limits in such future years. The Fund is a finite life and self-liquidating entity, and AFS and its affiliates have no recourse against the Fund for the amount of any unpaid excess reimbursable administrative expenses. The Fund will continue to require administrative services from AFS and its affiliates through the end of its term, and will therefore continue to incur reimbursable administrative expenses in each year. The Fund has determined that payment of any amounts in excess of the annual and cumulative limits is not probable, and the date any portion of such amount may be paid, if ever, is uncertain. When the Fund completes its liquidation stage and terminates, any unpaid amount will expire unpaid, with no claim by AFS or its affiliates against any liquidation proceeds or any party for the unpaid balance. For the year ending December 31, 2013, it is not anticipated that any further billings to the Fund will equal or exceed the annual or cumulative reimbursable expense limitation. Such is reflective of the continued diminishing Fund asset base over which reimbursements are calculated.

8. Members’ capital:

As of June 30, 2013 and December 31, 2012,  13,560,188 Units were issued and outstanding. The Company was authorized to issue up to 15,000,000 Units in addition to the Units issued to the initial Members (50 Units).

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.

As defined in the Operating Agreement, the Company’s Net Income, Net Losses, and Distributions are to be allocated 92.5% to the Other Members and 7.5% to AFS.

There were no distributions declared or paid during the three and six months ended June 30, 2013 and 2012.
