Unbilled receivables relate to contracts-in-progress for which revenue has been recognized but we have not yet billed the customer for work performed. We had $118,000 of retainage included in unbilled receivables at April 30, 2016 and virtually no retainage at July 31, 2015 and in the opinion of management, a majority of the total unbilled receivables at April 30, 2016 will be billed and collected within one year. Of the unbilled receivables from commercial and international customers at April 30, 2016 and July 31, 2015, $6,922,000 and $20,256,000, respectively, relates to our two large over-the-horizon microwave system contracts with our large U.S. prime contractor customer (all of which related to our North African country end-customer). As of April 30, 2016, the U.S. government (and its agencies) and Verizon Communications Inc. (through various divisions) represented 37.6% and 10.1%, respectively of total accounts receivable. As of July 31, 2015, the U.S. government (and its agencies) and one large U.S. prime contractor customer (the majority of which related our North African country end-customer) represented 13.5% and 36.3%, respectively of total accounts receivable.
