Example 13, on CFA Volume 4, Reading 45, page 64
I can’t solve the Betas on Table 5 using the pureplay method cause there is no mentioning of the debttoequity ratio. The example only list the debttocapital ratio which I believe is not a variable to solve for the leveraged beta. Am I missing something?
Also, I’m having a problem solving for the WACC in Table 5 as well.
Appreciate it if someone can explain.
