The website link that ubasses gave you contains the following information under 'About Us - Business Ownership', so I really don't see how more plain it could get, reagarding information. You therefore need to contact the Registrars for Arcapita to find out the terms of the deal. If they paid cash you will be able to exchange shares for cash at the price paid in 2006. If they paid in shares you are entitled to shares in Arcapita.
