In the second quarter of fiscal year 2014, we initiated the design and implementation of a new enterprise resource planning (“ERP”) system, which is expected to be installed by the end of calendar year 2017. Amortization of the ERP system development costs will be computed by the straight-line method, commencing in the period when substantial testing is completed and the asset is ready for its intended use. Through November 30, 2015, we have capitalized $24.1 million associated with the project that includes $0.4 million of capitalized interest.
