For the three months ended June 30, 2022 and June 30, 2021, the majority of revenue recognized was from the deferred revenue balances at the beginning of each period. For the six months ended June 30, 2022 and 2021, approximately half of revenue recognized was from the deferred revenue balances at the beginning of each period. When revenue is recognized in advance of invoicing we record contract assets, which are included in prepaid expenses and other current assets on our consolidated balance sheets. As of June 30, 2022 and December 31, 2021, the balance of contract assets was $3 million and $4 million, respectively.

The aggregate balance of remaining performance obligations as of June 30, 2022 was $1,406 million. We expect to recognize $951 million of the balance as revenue in the next 12 months and the substantial majority of the remainder in the next 13-36 months. The aggregate balance of remaining performance obligations represents contracted revenue that has not yet been recognized, including contracted revenue from renewals, and does not include contract amounts which are cancellable by the customer and amounts associated with optional renewal periods.
