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.   </div> </div>falsefalsefalsenonnum:textBlockItemTypenaThe entire disclosure for commitments and contingencies.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name FASB Interpretation (FIN) -Number 14 -Paragraph 3 -LegacyDoc This reference is SUPERSEDED by the Accounting Standards Codification effective for interim and annual periods ending after September 15, 2009.
