Lease-related interests reflect below-market-rate leases purchased in store 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 31, 2015, these lease-related interests have weighted-average remaining lives of nine years for amortization purposes.

At January 31, 2015, customer lists and relationships are being amortized on a declining-balance method over the remaining lives of four years. The amortization from the customer lists and relationships is included within depreciation and amortization expense.

During 2014, 2013 and 2012, amortization of $1,629, $1,759 and $1,890, respectively, was recorded on customer lists and relationships. Amortization of $4,542, $4,543 and $4,696 was recorded for favorable and unfavorable lease-related interests during 2014, 2013 and 2012, respectively. The Company anticipates amortization associated with customer lists and relationships of approximately $1,500 in 2015, $1,370 in 2016, $1,262 in 2017, and $652 in 2018.
