The title link is to a video interview with Sir David Tweedie, chair of the IASB. Sir David is his usual engaging self, but steadfastly avoids admitting that mark-to-market accounting may have had something to do with the current crisis. The nearest he gets is to suggest that accounting in its current form may not be usable as a way of regulating bank lending. To me, this suggests that, if it can't be used for this purpose, it's not portraying the reality Sir David is so keen on.
