I am not familiar with the terms governing the preferred and whether or not they have a "coupon" attached (interest on initial investment), but "Preferred" usually just means that they get paid "first" (investment plus accrued and unpaid interest, if applicable) before regular common in the event of a "liquidation" of the company's assets (they also come before commons for dividend payments, but I do not think that is relevant here). Certain Preferred do allow for conversion into common (e.g., factoring in any accrued but unpaid interest, if applicable), but again, I am not sure of the terms governing the RGBP preferred. Other than any such "preferred return/unpaid accrued interest" (if applicable), preferred do not receive more $$ per share than ordinary common in the event of a buy-out Does anyone know if there is a coupon associated with the preferred? I'm not too worried either way- in the event of a buyout, there will be plenty to go around for all!
