I want to know the answer to the following question:
Who was the largest residential loan due diligence and securitization surveillance company?
All the background I'm provided with is that "In separate testimony to Financial Crisis Inquiry Commission, officers of Clayton Holdings—the largest residential loan due diligence and securitization surveillance company in the United States and Europe—testified that Clayton's review of over 900,000 mortgages issued from January 2006 to June 2007 revealed that scarcely 54% of the loans met their originators’ underwriting standards.". Is that enough to answer the question?
Answer: yes
