Yehudit Bronicki

Thank you, Rob, and good morning, everyone. Thank you for joining us today for the presentation for our first quarter 2012 results and outlook for the near future. We are very pleased with the financial results of the first quarter, which was strong by just about every measure. Total revenue increased 35% year-over-year to a record quarterly revenue with Electricity and Product segment revenues increasing 5% and 156%, respectively. Our combined gross margin percentage was 30.1% for the quarter, almost doubling our gross margin during the same quarter in 2011 and $41.9 million cash flow from operations, the highest pure operating cash flow ever. We believe the numbers are a testament to the prudent approach we have taken to growing our business, while also ensuring an effective cost control.

In the Product Segment, 2011 was a record year in booking of new orders. We continue to be awarded new contracts in the beginning of the year. We recorded record high revenues in Q1, thanks not only to the strength of the Product Segment, but to improved results in the Electricity segment as well. By reducing the operating cost to all the fleet, but in particular at North Brawley, results improved in all parameters, including gross margin, operating cash flow, net income and EBITDA.
