We bill customers for power plant and module kit sales based on certain contractual milestones being reached. We bill SA's based on the contract price and billing terms of the contracts. Generally, our advanced technology contracts are billed based on actual recoverable costs incurred, typically in the month subsequent to incurring costs. Some advanced technology contracts are billed based on contractual milestones or costs incurred. Unbilled recoverable costs relate to revenue recognized on customer contracts that have not been billed. Accounts receivable are presented net of an allowance for doubtful accounts of $0.06 million and $0.01 million as of July 31, 2014 and October 31, 2013, respectively.

Commercial Customers accounts receivable (including Unbilled recoverable costs) include amounts due from POSCO Energy of $12.6 million and $17.4 million as of July 31, 2014 and October 31, 2013, respectively.
