[1] Unbilled receivables relate to revenue recognized in excess of amounts invoiced as the Company has an unconditional right to invoice and receive payment in the future related to its fulfilled obligations.

[2] Contract assets relate to unbilled receivables (including a long-term balance of $784 presented in other long-term assets as of December 31, 2021), which represent revenue recognized on arrangements for which billings have not yet been presented to customers because the amounts were earned but not contractually billable as of the balance sheet date, and the right to consideration is generally subject to milestone completion, client acceptance or factors other than the passage of time.
