This is for those US shareholders who might think that they cannot sell their rights. I was able to do so, but had to do it on the Canadian market.
I exercised about 2/3 of my rights. I asked about selling the remaining 1/3 and was told that I could not do it on the US markets, but then they put me in touch with their International Department and I sold them on the Canadian market. Had to pay a fairly high comission, but I was able to sell them. My broker is Fidelity. My sales price was $0.041.
