In my case I have 30,000+ that expire 12/31/16 and 85,000+ that expire 12/31/17. So I will have to use up the points within that timetable or they will disappear in each yearly subset. Those earned Jan 1-31 2016 must be used by 12/31/18. Points accrued from this Feb 1 onward are in a new "basket" of points that don't expire as long as there is some requisite activity within the 18 month window.
(So there is no grandfathering of "old" points into the "new" system. - That's my read on it.)

Confused? Yep.
