erpy...depends on the 20 day Aurora's VWAP on TSX. If the Aurora's PPS goes up but the VWAP on TSX stays at $5.30 or below, the share exchange ratio stays at 4.525 and subject to a cap price of $24 Canadian. This is how I understand by reading the Terms of the Offer. The rest is about PPS movements of both tickers on TSX to calculate the premium. Please see my post # 4520.
