We bill customers upon project milestones being reached. We bill SA's based on the contract price and billing terms of the contracts. The majority of advanced technology contracts are with the U.S. Government. We bill the U.S. Government based on actual recoverable costs incurred, typically in the month subsequent to incurring costs. The remainder of advanced technology contracts are billed based on milestones or costs incurred. Unbilled recoverable costs relate to revenue recognized on customer contracts that have not been billed as the milestone billing date had not yet been reached. Unbilled amounts at October 31, 2013 included $17.8 million due from Dominion under the Bridgeport fuel cell park project and $6.7 million due from POSCO Energy. Accounts receivable are presented net of an allowance for doubtful accounts of $0.01 million and $0.6 million at October 31, 2013 and 2012, respectively.

Commercial customers accounts receivable (including Unbilled recoverable costs) are amounts due from POSCO Energy of $17.4 million and $18.1 million at October 31, 2013 and 2012, respectively.
