Receivables from non-U.S. government customers include amounts related to long-term production programs for the Spanish Ministry of Defence of $2.5 billion on December 31, 2012. A different ministry, the Spanish Ministry of Industry, has funded work on these programs in advance of costs incurred by the company. The cash advances are reported on the Consolidated Balance Sheets in current customer advances and deposits and will be repaid to the Ministry of Industry as we collect on the outstanding receivables from the Ministry of Defence, leaving a net receivable of $28 on December 31, 2012. With respect to our other receivables, we expect to collect substantially all of the December 31, 2012, balance during 2013.
