Contract Assets and Liabilities
A contract asset is recognized when the Company has recognized revenues prior to generating an invoice for payment. Contract assets are classified separately within the unaudited condensed consolidated balance sheets and transferred to accounts receivable when rights to payment become unconditional.
A contract liability is recognized when the Company has advance payment arrangements with customers. The contract liabilities balance is normally recognized as revenue within six months.
