If I'm clear, you're suggesting that your internal audit committees did identify some of these things, but just not everything. Will you be upping the game of the audit committees too, to make sure they can do a more comprehensive job?
You're right that in a perfect world, you wouldn't make any mistakes. If you did make any mistakes, your internal audit committee would find it. In a worse case, they don't, and luckily the AG rolls in.
I assume you're going to try to beef up that capacity so they would find more of these kinds of things, because they slipped through the cracks of your audit committee, obviously.
