As long as the points have not been banked by you, they can still be transferred. The receiving member can then bank them for use from December 1, 2013 thru November 30, 2014.
MS has been allowing transfers from your 2012 Use Year into the other member's 2012 Use Year - so hopefully the other member has an August, September, October or December Use Year to accept a transfer of points from the 2012 Use Year. All other 2012 Use Years have already expired.
