Are Banks Misrepresenting Value to Investors

Peter Beller for Forbes.com in his article, See No Evil Accounting reports that some banks are avoiding writing down the value of their troubled commercial real estate loans by avoiding "placing a firm value on buildings that have likely fallen sharply in price," also citing writings by Joe Morford, who monitors bank stocks for RBC Capital.

Although I have some knowledge on the subject and probably enough to get myself in trouble, but this sounds a lot like something that each bank's auditors and the SEC should know about.  It seems to me that if banks are intentionally avoiding valuing the properties that their loans are based upon, they are artificially propping up the value of their own stock.  I wonder what the banks investors and stockholders would think about that and how these actions might be effecting the decisions to buy or sell stock.
