<prompt> Human: First off, I want to thank everyone for taking the time to read this post. I had never been in a situation like this and Im looking for any advice on how to proceed.Back in 1971 my father purchased 1000 shares in Bahamas Caribbean Dev. Corp. LTD, at .76 per share on Toronto Stock Exchange. From what I can gather since then, on Mar 24 1972, Bahamas Caribbean Dev. Corp. LTD became OCEA Oceanus Industries Bahamas Limited, 20 shares of Bahamas Caribbean Dev Corp LTD became 1 share of new company. Then on Sept 8 1983, Oceanus became a private company called Strean Investments and at that time the shares were redeemed at 5.15 per share. He may or may not have the original stock certificates of Bahamas Caribbean Dev. Corp. LTD. My questions are1 How does my father figure out how much his current asset are worth? 2 How does my father locate and claimsell this asset?  <response>: 1. First does your dad have the original stock certificate, if he does then he can contact any broker-dealer investment company or a bank that deals with investments and they can handle it from there.2. Your dad does not have the stock certificate you can still have a broker use a Bloomberg machine to research the back ground to find out the Treasury company for the stock so that person can contact the company.3. If you a sure about the redemption and your father never got he money it could of got escheated to your state and your state is holding the funds under your fathers name. So I would also try contacting the state to see if anything was escheated to them under your fathers name.
