Under a contract with a customer commencing in the final quarter of fiscal year 2020, the Company received advance payments to be used to pay providers of service to the customer, a separate third-party. The advanced payments are treated as restricted cash - current as the Company is required under the contract to distribute the advanced funds to the third-party providers or return the advanced funds to the customer. Because the Company receives the advance payments from the customer, which must be refunded to the customer or remitted to a third party, the cash receipts are treated as borrowings rather than receipts for the provision of goods or services. Therefore, these cash receipts are presented in the consolidated statements of cash flows as financing cash inflows, “receipt of restricted contract funds”, with the subsequent payments classified as financing cash outflows, “payment of restricted contract funds.” See Note 9 – Accrued Expenses and Other Liabilities for the corresponding liability.
