Thames reminds Cromwell that her model assumes zero interest rate volatility and a flat government yield curve. Cromwell responds that Thames should relax these unrealistic assumptions. Thames outlines the steps to take in valuing risky bonds under this scenario in Exhibit 1.
EXHIBIT 1 STEPS IN VALUING RISKY BONDS, ARBITRAGE-FREE FRAMEWORK
Which step in Exhibit 1 regarding valuing risky bonds has Thames most likely outlined correctly?
选项:
A.Step 1
Step 2
Step 3
解释:
Correct Answer: C
Thames is correct in describing Step 3 but incorrect about both Step 1 and Step 2.
The third point in Step 1 is explained incorrectly. The par curve where each bond is priced at par value, not the spot curve, is used to derive implied zero-coupon rates. In the second point of Step 2, she is incorrect regarding the recovery rate. The assumption is not based on credit ratings. The recovery rate if default were to occur should conform to the seniority of the debt issue and the nature of the issuer’s assets. For instance, a firm with a high ratio of assets relative to the debt level and debt senior in the capital structure will result in a higher recovery for bondholders than one with the reverse situation.
step1 不要用spot curve算出折现率吗?为什么错误?
