I want to know the answer to the following question:
What percent of CDO assets were subprime and other non-prime mortgage debt in 2007?
All the background I'm provided with is that "As described in the section on subprime lending, the CDS and portfolio of CDS called synthetic CDO enabled a theoretically infinite amount to be wagered on the finite value of housing loans outstanding, provided that buyers and sellers of the derivatives could be found.". Is that enough to answer the question?
