Answer:
The correct answer is 0.4%.
Step-by-step explanation:
According to the scenario, the computation for the given data are as follows:
If no debt, then required return can be calculated by using following formula:
Required return ( no debt) = Risk free rate + Unlevered Beta × Market risk premium
= 6% + 1 × 4%
= 0.06 + 0.04
= 0.10 or 10%
If debt, then required return can be calculated by using following formula:
Required return ( with debt) = Risk free rate + levered Beta × Market risk premium
= 6% + 1.1 × 4%
= 0.06 + 0.044
= 0.104 or 10.4%
So, extra premium required = 10.4% - 10% = 0.4%
