Hi, dyrrachium, and welcome to the FICO Forums!
FICO uses the average age of all accounts on your credit report. There is no part of the average age calculation that just looks at open accounts.
If they are positive accounts, they will stay on your reports for 10 years after they are closed, and in the meantime they will continue to contribute to average age.
Hope this helps!
