FRM Part I · FRM Exam Part I · Corporate Bonds

A 1-year zero-coupon corporate bond yields 7% and the 1-year risk-free rate is 3%, both with annual compounding. Assume a recovery rate of 40% on default and that recovery is paid at maturity. Using the approximation that the spread equals the default probability times loss given default, what is the implied 1-year default probability?

The implied default probability is about 6.67%. The spread is 4% and loss given default is 60% after a 40% recovery, so default probability is 4% divided by 0.60. Ignoring recovery would wrongly give 4%.

  1. A6.67%Correct
  2. B4.00%
  3. C10.00%
  4. D2.67%

Explanation

Spread = 7% - 3% = 4%. LGD = 1 - 0.40 = 60%. PD = 4%/0.60 = 6.67%. Ignoring recovery gives 4.00%; multiplying 4% by 0.6 gives 2.40%, and dividing by the recovery rate gives 10.00%.
