Contract balances
The timing of revenue recognition may differ from the timing of invoicing to customers. The Company has an unconditional right to consideration when it invoices its customers and records a receivable. The Company records a contract asset, or a receivable, when revenue is recognized prior to invoicing. The Company records a contract liability, or deferred revenue, when revenue is recognized subsequent to invoicing.
Deferred revenue includes amounts billed to customers for which revenue has not been recognized and consists of the unearned portions of edge cloud platform usage and billings to customers for the Company’s security subscription services. Amounts that have been invoiced for annual subscriptions, but not collected, are recorded in accounts receivable and in unearned revenue or in revenue depending on whether services have been delivered to the customer. The Company’s payment terms and conditions vary by contract type, and generally range from 30 to 90 days.
