Inventory

6 Months Ended

Jun. 30, 2011

We did not incur any temporary LIFO liquidation gain for the six months ended June 30, 2011 or 2010. During the three months ended June 30, 2010 and again during the corresponding period in 2011, we restored the $0.2 million LIFO liquidation incurred in the first three months of each year as a result of reductions in finished cement and work in process inventory.
