The program ends on December 15.
I'm actually in the opposite situation. I'm dangerously close to PM, and I'll be doing my best to avoid travel for the rest of the year so as not to lose my rollover MQM's. I wish it was as easy as transferring the rest of my year's MQM's to you.
Hope the above link helps.
