Thank you, Dexter. I know the Gazprom secondary listing ticker is OGZD, but both of my ISA providers declined to deal in it because of the dollar quote. Likewise the non-ISA broker I use, Halifax Sharedealing, would not deal in it either, although they will deal in foreign shares such as Berkshire Hathaway (NYSE:BRK.B), Trina Solar (NYSE:TSL) and Cameco (NYSE: CCJ, not the Toronto-traded CCO). I'm reluctant to open an account with another stockbroker because I've promised my wife to keep my affairs as simple as possible (financial affairs, I mean!) in case I kick the bucket.
