AIM 3: Compute the value of credit default swaps, given unconditional default probabilities, survival probabilities, market yields, recovery rates and cash flows.

1、The survival probabilities and unconditional default probabilities for Bote Corp are listed in the table below. Baltimore Bay Investments has entered into a 4-year credit default swap (CDS) with Phili Investments to hedge against the credit risk of a $50 million bond issued by Bote Corp. Assume that payments on the CDS occur annually at the end of the year, and that defaults on the CDS occur halfway through each year. The risk-free rate is 6 percent, compounded continuously, and the recovery rate in the event that Bote Corp defaults is 40%. The probability that Bote Corp defaults during a year, conditional on no-earlier default is 2 percent.

Time (Years)	Default Probability	Survival Probability
1	0.0200	0.9800
2	0.0196	0.9604
3	0.0192	0.9412
4	0.0188	0.9224

Which of the following is closest to the present value of the total expected payments made by the buyer of the CDS?

A)    3.28s.

B)    3.98s

C)   5.61s

D)   3.32s.

The correct answer is B

Since the swap buyer receives the total return of the reference asset, she assumes the asset’s credit risk. The swap buyer does not purchase the underlying asset and pays LIBOR + a spread.

The correct answer is D

Present value of the expected payment in the event of default:

Time (Years)	Probability of Default	Recovery Rate	Expected Payoff ($)	PV of Expected Payoff ($)
0.5000	0.0200	0.4000	0.0120	0.0116
1.5000	0.0196	0.4000	0.0118	0.0108
2.5000	0.0192	0.4000	0.0115	0.0099
3.5000	0.0188	0.4000	0.0113	0.0092
			TOTAL	0.0415

The present value of the expected payment in the event of default is .0415.
