Thank you, Karen. I am pleased to report that we achieved record production of 5.4 million gallons of renewable products at our Geismar Plant during the month of July. July figures imply 65 million gallons annual production. The Geismar Plant was designed to produce 75 million gallons per year. We have now produced over 19.3 million gallons of products through the end of July. We continue to expand, stay improved in both reliability and production. In May, June and July our production was 3.1 million, 3.6 million, and 5.4 million gallons respectively. Since we began plant start up and commissioning last October, we have focused our efforts on reaching design capacity. During commissioning, we modified plant equipment to improve reliability, which is reflected in our 87% uptime July numbers. Let us review the performance for the last 10 months. We will focus on three items, feedstock cost, revenues and operating expense. For the prior 10 months, our average feedstock cost have been $3.68 a gallon and our blended revenue was $4.98 per gallon resulting in a gross margin of $1.30. This compares to weighted average soy based bio diesel gross margin of $0.76 per gallon for the same time period. Our average operating expense was $2.96 per gallon, which equates to the net loss of $1.66 per gallon through June. The $2.96 per gallon occurred during our commissioning and start-up period when we averaged 25% of design and capacity. Based on preliminary cost in July, we believe our original operating expense of $0.50 to $0.55 per gallon is attainable. This is especially true given our budget originally included $0.19 per gallon of hydrogen cost. Due to improved plant performance and favorable natural gas costs, we achieved $0.14 per gallon hydrogen cost in July.
