Operating leases

The Group’s leases consist of operating leases for corporate offices, data centers, and other facilities. The Group determines if an arrangement is a lease at inception. Some lease agreements contain lease and non-lease components, which the Group choose to account for as separate components. The allocation of the consideration between the lease and the non-lease components is based on the relative stand-alone prices of lease components included in the lease contracts. As of December 31, 2022, the Group had no long-term leases that were classified as a financing lease. As of December 31, 2022 the operating leases that have not yet commenced is immaterial.
