sent a SM about being matched to 5k for an AU:
Dear *********l,
Thank you for contacting us concerning the rewards bonus
points on your Chase Sapphire Preferred account.
I would like to inform you that the 5,000 bonus points
offer for adding an Authorized User is applicable on
accounts that are opened on or after 11/18/2013. As your
account was opened prior to this date, I regret that we
are unable to match the offer on your account.
