RE: FEZGUYTKMRF is the Pink Sheet symbol for Tekmira (TKM.TO). So most US brokers will use TKMRF to identify Tekmira on statements or for trades. However, in most cases, the broker will route the trade directly to the Toronto Exchange and not use a Pink Sheet market maker. (You should check with your own broker for their policy.) At least at TDAmeritrade, having a Pink Sheet symbol makes it easier to trade Tekmira as you can now do it online without calling a broker.
