I dont think a black out in itself is any kind of news. There has been a black out called on every news release that may affect share price, and I dont recall them ever announcing them publically. Its nothing to take to the bank. Its simply a formality that prevents managenment from taking advantage of news that others are not able to see. Management know how hungry everyone is for some kind of info and thought theyde throw that out there . If your looking for some formal notice ,I dont think you'll get it.
