As I understand the Citi Exec card & Aadvantage rules, it doesn't matter when the 10k EQMs post, as they apply only to this year, i.e. if you go over $40k by the December-2013 statement date, you get the EQMs for 2013. So it doesn't make any difference if they don't show up until January or February 2014.
The only time it appears that the exact posting date would matter is if you need some of the 8 new SWUs soon that you would get after the EQMs post, assuming that post puts you over 100k total.
In my case, I went over $40k spend on my late Oct. Citicard statement, but as I have 4 eVIPs still in my account with no travel 'til January, I don't care much when the 10K EQMs post.
