What attribute determines if password is almost expired?

What attribute determines if password is almost expired?

Hi All,
I'm working with fine grained password policies in Active Directory, and  we use this service to send out password expiration email reminders. I wanted to find out what ADSelfService Plus uses as an attribute for determining passwords that are about to expire. Is it "msds-userpasswordexpirytimecomputed" or something else?
Thanks!
Jack
