Interesting...does seem strange. We flag all of our employee, director, officer, and executive officer accounts. There is a separate function that controls who can view these accounts. Most employees do not have access to see E/D/O/EO accounts; however, any employees that have to post to accounts has access.
If the accounts don't get marked, how do you give a listing/download of employee accounts to examiners when they ask? What a pain if it needs to be done manually.
