3. Commitments and contingencies Leases   The Company leases retail stores, distribution and office facilities, and certain equipment. Original non-cancelable lease terms range from three to ten years, and leases generally contain renewal options for additional years.

Total rent expense under operating leases was $44,558 and $38,538 for 13 weeks ended May 2, 2015 and May 3, 2014, respectively.
