In 2011 and 2010, our Board of Directors approved the construction of a U.S. mineral wool plant to supply our Building Products plants, the allocation of capital to double our Building Products production capacity in China, and the construction of two flooring plants in China. Total capital spending for these projects is currently projected to be approximately $200 million. Through December 31, 2011, we have incurred approximately $72 million related to these projects with most of the remaining spending to occur in 2012.
