15. Leases

The Company is obligated under operating leases for almost all of its store properties. Some of the store leases contain renewal options with varying terms and conditions. Management expects that in the normal course of business, expiring leases will generally be renewed or, upon making a decision to relocate, replaced by leases on other premises. Operating lease periods generally range from 5 to 10 years. Certain leases provide for additional rent payments based on a percentage of store sales.

Most of the Company’s leases require the payment of certain executory costs such as insurance, maintenance, and other costs in addition to the future minimum lease payments. These costs, including the amortization of lease rights, totaled $132 million in 2014 and $128 million in both 2013 and 2012. Included in the amounts below, are non-store expenses that totaled $17 million in 2014 and $16 million in both 2013 and 2012.
