I want to know the answer to the following question:
According to Clayton Holdings, how many mortgages issued from January 2006 to June 2007 met underwriting standards?
All the background I'm provided with is that "Clayton's analysis further showed that 39% of these loans (i.e. those not meeting any issuer's minimal underwriting standards) were subsequently securitized and sold to investors.". Is that enough to answer the question?
