Lease-related interests reflect below-market-rate leases purchased in acquisitions completed in 1992 through 2006 that were adjusted to reflect fair market value. The lease-related interests, including the unfavorable lease-related interests included in other long-term liabilities, are being amortized on a straight-line method and reported as "amortization of lease-related interests" in the consolidated statements of operations. At January 30, 2016, these lease-related interests have weighted-average remaining lives of nine years for amortization purposes.

At January 30, 2016, customer lists and relationships are being amortized on a declining-balance method over the remaining lives of three years. The amortization from the customer lists and relationships is included within depreciation and amortization expense.

During 2015, 2014 and 2013, amortization of $1,500, $1,629 and $1,759, respectively, was recorded on customer lists and relationships.
