For our bank, I coordinate external audit and regulatory exams. I am the go-to person for anything the auditors might need. If they have questions, they come to me and if I can't answer, I send them to the right place - or I contact management. This is just how our bank has done it. It speeds up the external audit process and is very efficient according to our external auditors. When we get our prep package, I hold a meeting with everyone I need to get information from and we delegate who will get what. But as far as questions from the auditors, they always contact me. Sometimes they will contact Sr. Mgmt, but 95% of the time, they coordinate with me. Regulators are a little different and I coordinate their prep package as well, however, when they are here, they don't come to me as often. They usually know who they want to talk to.
As far as reports, you as the auditor should get a copy of all reports, be in the exit conference, and get a copy of any managment responses. You don't do anything with mgmt response, preparation of the audit report, etc. You should just be in the know! Hope that helps.
