Over 520 million f. d so far, but likely further increased as the 520 takes into account the current dilution of the converts whereby the converts are converted at 1.20 or something. Too lazy to look up the convert feature as sedar is now a pain to use.
i.e if they convert the debeture at the current share price ( sometihing I'm fearing as the ceo does't care about dilution) we get another blast of dillution. That will take us well over 550 million share outstanding. So don't go by the understated current basic share count when taking into account valuation metrics.
