To find details about a particular round, click on the Current Investments link on the left navigation. At the top of the table, click on the By Round tab. Clicking on any round name will give you details about that round, such as price per share, closing date, etc.
Another way to get details on a round is to click on the Portfolio Management link and then the Rounds Tab. Every round you have added to Seraf appears here in alphabetic order, although you can also sort by Security Type or Closing Date. Regardless, clicking on a round name will bring up the details.
