The deadline for Fairfax Financial to come up with the money to finance its takeover bid expires at 5:00 pm EST today. Since the deal was announced, shares have been falling farther and farther away from the $9.00/share bid price instead of getting closer as is usually the case. This suggests the street has been increasingly expecting the deal to fall through. If it does collapse, this could open the door to other suitors to come in without having to deal with the break fee, but their offers could be significantly lower. Press reports this morning suggest that Blackberry is about to abandon its sale plan and replace its CEO. The shares traded sharply lower in pre-market action before being halted. However this all shakes out, Blackberry shares have the potential to be quite volatile over the next 24-48 hours and could potentially create a number of trading opportunities.
