As of December 31, 2022, the Company expects to recognize 52% of its total deferred revenue within the next 12 months, 21% of its total deferred revenue between 13 and 36 months, 24% between 37 and 60 months. Any deferred revenue expected to be recognized beyond five years is immaterial. Contracts may contain termination for convenience provisions that allow the Company, customer, or both parties the ability to terminate for convenience, either at any time or upon providing a specified notice period, without a substantive termination penalty. Included in deferred revenue as of December 31, 2022 are $39,932 of prepaid fees related to contracts with termination for convenience provisions which are refundable at the request of the customer. Based on the Company's historical experience, customers do not typically exercise their termination for convenience rights.

Deferred cost of revenue includes all direct costs included in cost of revenue that have been deferred to future periods.
