So, I was contemplating a piece on the Assurance aspects of the SEC’s interactive data proposals, now that there are a number of statements on the subject from the audit firms. But it turns out that Jim Hamilton has written a great analysis of the comment letters from the audit firms’ positions on audit and XBRL. So I don’t have to. Recommended reading. Some background from my perspective, here.
