Leasehold Financing Obligations	13. LEASEHOLD FINANCING OBLIGATIONS As of April 28, 2012 and January 28, 2012, the Company had $65.7 million and $57.9 million, respectively, of long-term debt related to the landlord financing obligation. In certain lease arrangements, the Company is involved with the construction of the building. If the Company determines that it has substantially all of the risks of ownership during construction of the leased property and therefore is deemed to be the owner of the construction project, the Company records an asset and related financing obligation for the amount of the total project costs and an amount related to the pre-existing, leased building, which is included in Property and Equipment, Net and Leasehold Financing Obligations, respectively, on the Consolidated Balance Sheets. Once construction is complete, the Company determines if the asset qualifies for sale-leaseback accounting treatment. If the arrangement does not qualify for sale-lease back treatment, the Company continues to amortize the obligation over the lease term and depreciates the asset over its useful life. The Company does not report rent expense for the portion of the rent payment determined to be related to the properties which are owned for accounting purposes. Rather, this portion of the rental payments under the lease are recognized as a reduction of the financing obligation and interest expense. Total interest expense was $2.2 million for both the thirteen weeks ended April 28, 2012 and April 30, 2011.
