You would like to know the beta of debt for KT Industries. The value of KT's outstanding equity is $50 million, and you have estimated its beta to be 1.62. You cannot, however, find enough market data to estimate the beta of its debt, so you decide to use the Black-Scholes formula to find an approximate value for the debt. KT has a five year zero coupon bond outstanding with a market value of $80 million. If the estimated D from the Black-Scholes model is .60, then the beta for KTs debt is closest to: A) 1.00 B) 0.59 C) 0.90 D) 2.70
