22. Financial engineering refer to creation of new securities Bundling: combine more than one security into a composite security Unbundling: breaking up and allocating the cash flows from one security to create several new securities

23. Collateralized Debt Obligation (CDO) A CDO is an asset backed security (ABS) whose underlying collateral is typically a portfolio of bonds (corporate or sovereign) or bank loan A CDO cash flow structure allocates interest income and principal repayments from a collateral pool of different debt instruments to a prioritized collection (tranches) of CDO securities.

24. Mortgage 1 Mortgage 2 Mortgage 3  Mortgage n Average Yield 12.5% ($100 mil) Tranche 1 (AAA) Yield = 5% ($25mil) Tranche 2 (A) Yield = 10% ($25mil) Tranche 3 (BBB) Yield = 15% ($25mil) Tranche 4 (junk bond) Yield = 20% ($25mil) Cash CDO Structure Illustration An investment bank creates a set of securities (tranches) backed by a mortgage pool (CDO) Investor: banks, pension funds, college saving funds, universiti es, cities, etc.

25. Collateralized Debt Obligation (CDO) In normal time, mortgage borrowers are able to make the mortgage payments, so the investors will get the interest payments, the values of slices of CDOs increase When housing bubble busts, mortgage borrowers, especially subprime mortgage borrowers are not able to make payments, investors don’t get their money, values of CDOs decrease substantially. The value decrease is write-down and counted as loss in the income statement. For example, investment bank A, equity: $10 mil, borrow $90 mil. Invest all $100 mil in CDOs. When mortgage crisis happens, the market value of these mortgage backed securities drops substantially say to $80 mil, that means the income will go down by $80 mil, and at this point, technically the bank is insolvent.

Big losers:  Citigroup ($18B+)  Merrill Lynch ($11.5B+)  UBS ($17.8B+)  Morgan Stanley ($9.4B+) …  Bank of China (initial estimate $223 million, now could be $4-5B)
