Emerging Market FinanceLecture 14: Valuation of Corporate Bonds
Corporate Bond BT = X if VT > X or = VT if VT < Xwhere VT is the value of the firm at bond maturity T, and X the face value of a zero-coupon bond.
Example • Company ABC: • Vt = $1 billion, • ROA = 10%, • Volatility(ROA) = 30%。 • Consider a 5-yr zero-coupon bond with $500 million face value。 • Then, the probability of bankruptcy in yr. 5 = 21.32%。
Relationship between Bond Maturity and Probability of Bankruptcy Years to Maturity
Standard Textbook Calculation • According to standard textbook,Bt = {500*p + E(VT) * (1-p) }/(1+r)^(T-t)where p = prob of No bankruptcy in yr 5 and E(VT) = the expected value of the firm if bankruptcy occurs • If r=2%,then Bt = $450.6 million • and 5-yr corporate bond yield =3.53%
If no recovery of value at bankruptcy, then the picture differs • Bt = 500*p /(1+r)^(T-t) • Bt = $407.6 million And the 5-yr bond yield = 7.05%。
