Suppose that the yield on a 1-year T-strip is 1.55% and the yield on a 2-year T-strip is 3.90%. The yield on a 1-year, zero-coupon corporate bond is 5.80%, and the yield on a 2-year, zero-coupon corporate bond is 10.30%.
Use the information to answer the question: What is the cumulative probability of default for the corporate bond over the 2 years?
