I've seen the valuations for Zenith fluctuate from time to time in my brokerage accounts.  BMO Investorline periodically (every 3-6 months) will re-evaluate non-traded private companies and give them a new valuation based on current knowledge of things they might have disclosed publicly.  We know that the recent financing was for $2 USD, so it makes sense that some brokerages would now value Zenith at $2.60 CAD.
