The restructured mortgages need to earn the prime status they should not before have been awarded.

Sir the chairman of the US Federal Deposit Insurance Corporation Sheila Bair opined on "How the state can stabilize the housing market", April 30.

She describes the pros of some current options but misses out on what is the most important rule of any restructuring namely that if you are going to pay for the costs of restructuring, this is normally only worthwhile to do, if you get it right once and for all; and that what is left in the pot is deemed as being of much better risk quality than what went in. In other words the resulting mortgages should have to earn the real prime status they should never before have been awarded.

In this respect when Bair states as a clear advantage that "it keeps the risk of re-default on mortgage investors", though it sounds about right, it should be irrelevant if the restructuring has been done correctly and the risk of re-default are negligible.
