Steps to close down a company gl segment that is no longer needed

 in 11.5.10 ebs, we have a company (first segment of a 4 segment gl flexfield string) who has has activities and transactions for a company defined as '02'.  The company has now been closed and the account needs to be disabled.  Other companies (identified with unique 2 digit company segment) remain active and are not to be modified.

Assumption is that the books have been closed and audited and no more transactions will occur.

Outside of disabling that GL flexfield key segment value, what are other considerations that should be reviewed?

Thank you.
