[1] | Lease expense and sublease income represent the amount recorded within our unaudited condensed consolidated statements of income and comprehensive income. Variable lease amounts represent expenses recognized as incurred which are not included in the lease liability. Fixed lease expenses and sublease income are recorded on a straight-line basis over the lease term and therefore are not necessarily representative of cash payments during the same period.
