Federal bank regulators issued guidelines allowing banks to keep loans on their books as 'performing' even if the value of the underlying properties have fallen below the loan amount.

The volume of troubled commercial real-estate loans is skyrocketing. Regulators said that the rules were designed to encourage banks to restructure problem commercial mortgages with borrowers rather than foreclose on them. But the move has prompted criticism that regulators are simply prolonging the financial crisis by not forcing borrowers and lenders to confront, rather than delay, inevitable problems.
