The increases in goodwill and other intangible assets during the six months ended March 31, 2012 principally reflect the effects of the Heritage Acquisition and, to a much lesser extent, the Shell Acquisition. Amortization expense of intangible assets was $13.0 and $18.8 for the three and six months ended March 31, 2012, respectively, and $4.9 and $9.6 for the three and six months ended March 31, 2011, respectively. No amortization is included in cost of sales in the Condensed Consolidated Statements of Income. As of March 31, 2012, our expected aggregate amortization expense of intangible assets for the remainder of Fiscal 2012 and for the next four fiscal years is as follows: remainder of Fiscal 2012 — $27.4; Fiscal 2013 — $52.7; Fiscal 2014 — $51.7; Fiscal 2015 — $49.7; Fiscal 2016 — $46.4.
