And today, management is going to discuss certain topics that may contain forward-looking information which is based on management's beliefs, as well as assumptions made by management and information currently available to them. Forward-looking information includes statements regarding the expected future drilling results, production, expenses, reserves. And although management believes that these expectations reflected in such forward-looking statements are reasonable, they can give no assurance that such expectations will prove to be correct. And such statements are subject to certain risks and uncertainties and assumptions, which are listed and described in the company's filings with the Securities and Exchange Commission. If one or more of these risks materialize or should underlying assumptions prove incorrect, actual results may differ materially from those expected. And also, today's call may include discussion of probable or possible reserves or use terms like volumes, reserve potential or recoverable reserves. And please note that these estimates are non-proved reserves or resources that are by their very nature more speculative than estimates of proved resources and reserves and accordingly, are subject to substantially greater risks.
Now with that, I'll turn the call over to Bob Herlin, Evolution's Chief Executive Officer. Bob?
Thanks, Lisa. Good morning, everyone. Certainly appreciate you joining the call today. I'll briefly review reserves in operating results and then update you on our future plans. Sterling, our CFO, is here today and he will highlight some of our select financial information and then we'll take your questions.This morning, we put out a press release that reported our substantial increase in proved reserves and our improved financial and operating results for the fourth quarter and year ended June 30. Now these results are primarily due to the success of the Delhi project, which has continued to performed well. Let's start with reserves first as of June 30, 2011, end of our fiscal year. Overall, we're very pleased to report that our proved reserves increased substantially some 11.5% to a total of 13.8 million barrels of oil equivalent and that's obviously net of production during the year, sales in place and any revisions. Our PV-10 increased by 41% to a total of $375 million. In particular, our proved developed reserves, almost all of which are producing, increased 378% to a total of 5.3 million barrels equivalent. Proved developed reserves now total 39% of our total proved category. Probable reserves, 94% of which are associated with Delhi are a total of 6.2 million barrels equivalent with a PV-10 of $76 million. I'd also like to point out that about 30% of our probable reserves are actually in a developed producing category and obviously, that would be all at Delhi.
