Additionally we did not incur a temporary LIFO liquidation gain during the three months ended June 30, 2013. For the three months ended June 30, 2012, we restored a $0.5 million LIFO liquidation incurred in the first three months of 2012 as a result of reductions in finished cement and work in process inventory. The temporary LIFO liquidation gain had been deferred as a component of accrued liabilities.
