Hmmm. Last year I definitely had to subscribe to some random magazines I didn't really want because the value was about to expire, and only something like 25% of the remaining balance was carried over into the new year. (I had built up a big balance due to a particularly lucrative focus group study, and wasn't careful about redeeming HHonors points along the way (limited to once per quarter).)

Fingers crossed - this would be a significant improvement to the program for me if I don't have to worry about expiration anymore.
