not correct I bought HPNN in 2010/11/12 I had a letter from my bank Oct. 2013 ( bank in switzerland/europe, I'm swiss ) Broker like to delete my Position worthless, because never will be tradable again. I said NO. I will look for a other account, where Position has to be bring in. Said and done. Now my Broker ( in US ) is in big troubles. He has to bring my Shares ( 40M). Looks like he sold me short. Like proof ? Will send you letter by mail ( in german )
