9bruce I have been in charge of annual audits from a company side many times. What it comes down to is this. Once audit firm is done with all the field work. They send any proposed audit adjustments to what the company had for financial reports. Then the process starts between the company and auditors to agree on final changes. That starts a back and forth. Then the auditors will post the changes send draft of financial audit reports including financial reports etc to review. Then that can drive more changes.
A lot of how long that takes depends how fast companies review and respond. How many changes to what auditors first propose.
Then once it's all agreed to by both sides and final next depends on what auditors schedules are. They can promise final delivery by a date but is all depends on when they can get it done.
From what I see the auditors are telling him weeks are needed based on their schedules. They have more then one client they audit at a time. It will get done but when they can. I used to get upset sometimes when they did not get it done when I wanted it but it happens all the time.
