You guys are making something that is simple, complicated. The Special will be handled just like any other quarterly dividend. There will be a Declaration Date, Ex-Dividend Date and Record Date. Those dates will either be very close to or most likely Exactly matching the dates for the regular Q4 dividend.
In regards to the New shares (the $100mm, if it happens), its my understanding they must be issued prior to the dividend payment so they'll get the special but those shares will abide by the same "rules" as the common. If they are issued prior to the X dividend date, they'll get the Special.
