[1] Under a contract with a customer that commenced in the fourth quarter of fiscal year 2020, the Company received advance payments to be used to pay providers of services to the customer, a separate third-party. The advanced payments are treated as restricted cash as the Company is required under the contract to distribute the advanced funds to the third-party providers of services 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 and recorded in restricted cash and accrued expenses and other current liabilities 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.”
