These calculators use imbedded Active-X Microsoft spreadsheets. Security settings on Internet browsers may prohibit downloading of these components.  One solution to this problem is to reduce the browser security setting while using this class exercise.  Because the component is a Microsoft spreadsheet, browsers other than Internet Explorer may also have downloading problems.  If you are behind a company firewall, there is nothing that can be done about it. For security reason, there is no way to get around the browser based security settings. Please contact PetroStrategies if you are experiencing these problems. 

If your browser will not allow you to download the following applications, you may access the material in a Microsoft Excel Spreadsheet.
