Yes FMV is much more usefull to shareholders.

But!! FMV is much more difficult for a company which is not listed to provide and much more judgment is required.  FV can be (generally speaking) mechanically generated and does not come with nearly as much exposure to lawsuits as a FMV pronouncement would involve.

the only FMV is what a willing buyer and a willing seller can establish and even in a listed stock the actual value at which it trades can be argued from too high or too low with equal enthusiasm.

When I look at ZCC i would not be willing to sell it even at $20.00 or $30.00 but I have no money to spare and I would not be willing to buy even at $1.00 or less as I am overextended in RVX and ZCC. 

I face the issue that I would make a great deal of money selling my RVX at today's price and thus pay a large amount of tax; but I think it is worth a great deal more.

I am continuing my gamble on the results of BoM. Oh but how I will regret not selling if the Phase 3 does not succeed. I am willing to gamble and in the past I have sometimes won and sometimes lost. This time with all I have been able to look at and judge I feel right in holding.

I remain happy that I placed my Shares of ZCC in my TFSA as soon as I could.
