In accordance with accounting guidance in moving Diberil to a fully consolidated basis, we remeasured the previously held 50% noncontrolling interest in Diberil to fair value and recognized a non-cash write-down of $7.7 million during the period.Including its consolidated and equity basis results, Diberil contributed $2.3 million of income before income taxes for Q2 FY2013, compared to $0.8 million in the same period last year. Results at Diberil have improved over last year due to good performance on a river crossing project in the Amazon. Excluding results from Diberil, for Q2 FY2013 Geoconstruction Division revenues increased $6.8 million due primarily to progress on a ground stabilization project in Washington D.C. Income before income taxes was down approximately $1.0 million from the prior year, as last year's earnings included a dam stabilization project that ended with much better performance than expected. Upfront start up costs on more recent projects this year also had an adverse impact on income before income taxes. The backlog in the Geoconstruction Division was $71.5 million as of July 31, 2012, compared to $57.0 million as of April 30, 2012, and $50.5 million as of July 31, 2011.
