Operating lease, option to extend |  |  |  |  |  |  | The Company’s store leases typically contain options that permit renewals for additional periods of up to five years each. In general, for store leases with an initial term of 10 years or more, the options to extend are not considered reasonably certain at lease commencement. For stores leases with an initial term of 5 years, the Company evaluates each lease independently and, only when the Company considers it reasonably certain that it will exercise an option to extend, will the associated payment of that option be included in the measurement of the right-of-use asset and lease liability. |  |  |
