James borrows $300,000 for a home from Bank A. Bank A resells the right to collect on that loan to Bank B. Bank B securitizes that loan with hundreds of others and sells the resulting security to a state pension plan, which at the same time purchases an insurance policy from a company called AIG that will pay off if James and the other people whose mortgages are in the security can’t pay off their mortgage loans. Suppose that James and all the other people can’t pay off their mortgages. Which financial entity is legally obligated to suffer the loss?

a. Bank A

b. Bank B

c. the state pension plan

d. AIG
