5. Unbilled Accounts Receivable

Unbilled accounts receivable represent revenues earned in connection with products and/or services delivered for which we are unable to issue a formal billing to the customer at the balance sheet due to either timing of invoice processing or delays due to fixed contractual billing schedules. A significant portion of our unbilled accounts receivable consist of carrier services and hardware and software products delivered but not invoiced at the end of the reporting period.

The following table presents customers that represent ten (10) percent or more of consolidated unbilled accounts receivable in the current and/or comparative period:
