Revenue; Accounts and Unbilled Receivables

Staffing services include the augmentation of customers' workforce with our contingent employees performing services under the customers' supervision, which provides our customers with a source of flexible labor at a competitive cost. Customer contracts are typically annual contracts but

may

be terminated upon

60

days' notice for any reason.

Contract Balances

— The timing of revenue recognition, billings and cash collections results in accounts receivable and unbilled receivables (the "Contract Assets"). The Company bills customers generally every other week based on the work performed during the

two

-week period ended the week prior to billing. Generally, billing occurs after revenue recognition, resulting in Contract Assets. The Company does

not

receive advances or deposits from its customers.
