The Group leases office facilities and other premises under non-cancelable operating lease agreements with various expiration dates. The Group determines whether an arrangement is or contains a lease at contract inception.

Operating lease right-of-use (“ROU”) assets and operating lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. When the rate implicit in the lease is not readily determinable, the Group uses its incremental borrowing rate based on the information available at the lease commencement date.

Operating lease expense is recognized on a straight-line basis over the lease term.
