Q4 revenue increased 26% and gross profit was 5% higher compared to Q4 2011. Strong demand for our contracts and project services was impacted by the decline in the value of our recovered products and reduced waste volumes in Heavy Oil facilities. Declines in the price of crude oil resulted in reduced prices received for our products of $1.0 million. Lower drilling activity in the WCSB resulted in lower utilization rates for drill site. Performance was positively impacted by waste volumes processed under our MFT contract in the quarter.
