[1] Within the revenue earned not billed line on the condensed consolidated balance sheet, $0.4 million is accounted for as a sales type lease under ASC 842, and therefore not considered a "contract asset", which is an asset defined by ASC 606.

[2] Includes the unamortized portion of the funds received from the federal government in 2010 and 2011 as reimbursement for the costs to build the two facilities related to the PPAs. As the transaction is not considered a contract with a customer, this value is not a contract liability as defined by ASC 606.
