Collateralized debt obligations (CDOs) are a type of structured asset-backed security (ABS) with value and payments derived from a portfolio of fixed-income underlying assets.
Collateralized loan obligations (CLOs) are CDOs backed primarily by leveraged bank loans. Collateralized bond obligations (CBOs) are CDOs backed primarily by leveraged fixed-income securities.
CDOs are assigned different risk classes, or tranches.
Problem: The majority of investors are paid a floating rate, whereas the underlying pool bonds pay a fixed rate. If rates rise, the collateral manager can get burned. This is because the manager could find itself having to pay out an increasingly higher rate to tranche holders while its source of funds - interest on the underlying bonds - is fixed.
Solution: The manager must protect against rising rates. Entering a swap as the fixed payer (variable receiver) solves the problem, as this position provides positive cash flow when interest rates rise.
Consider the following CDO transaction:
The equity tranche is $100 - $100 x 0.75 - 10 = $15 million.
Netting the interest payments paid and received:
$100 x (T-rate + 5%) - $75 x (T-rate + 1.5%) + $75 x LIBOR - $75 x (LIBOR + 0.5%) - $10 x (T-rate + 4%) = ($15 x T-rate + $3.1) million
If the five-year T-rate at the time the CDO is issued is 5%, the amount available each year for the equity tranche is $15 x 0.05 + 3.1 = $3.85 million.
Cash CDOs involve a portfolio of cash assets, such as loans, corporate bonds, asset-backed securities or mortgage-backed securities. Ownership of the assets is transferred to the legal entity (a SPV) issuing the CDOs' tranches. The risk of loss on the assets is divided among tranches in reverse order of seniority.
Motivation - Arbitrage vs. Balance Sheet

|ynaghibi: So the sr class of the synthetic cdo gets a periodic payment that is a part of the swap premium even though the swap transaction was with the jr class? Or does the sr class get paid some predetermined lesser rate that is pegged to the reference asset in return for taking on the lesser amount of credit risk? I think I get everything except that.|
|sahilb7: Can someone explain from where we get the (15 x T-Rate+$3.1) in this example? I think I am missing something.|

|guest: CFAi book on Pg. 511 has an example (EX-12) where it says that the risk due to potential mismatch between the collateral making fixed rate payments and bond classes making floating rate payments is characteristic of ABS and not CDOs. Confused between the risk differences of ABS, arbitrage CDOs, and regular CDOs.|
