From your link: Getting candidates on the board gives supporters a better shot at influencing company policy. It will be in place in time for next spring's corporate elections season.
If the PTSC SHM is in the fall or winter I don't see how this will help now. Of course the BOD could delay the meeting until the Spring.
Honestly, does the ruling really help those wanting to make a BOD change now? Can it be applied now? Or do we have to wait for a whole year?
