I want to know the answer to the following question:
During 2007, what was the percent of defective mortgages not underwritten to Citi's standards?
All the background I'm provided with is that "Moreover, during 2007, "defective mortgages (from mortgage originators contractually bound to perform underwriting to Citi's standards) increased... to over 80% of production".". Is that enough to answer the question?
