UNBILLED RECEIVABLES

4. UNBILLED RECEIVABLES

Unbilled receivables represent revenue recognized not yet billed. Unbilled receivables are calculated for each individual project based on the proportional delivery of services at the balance sheet date. Billing of amounts in unbilled receivables occurs according to customer-agreed payment schedules or upon completion of specified project milestones. All of Lionbridge’s projects in unbilled receivables are expected to be billed and collected within one year.
