a. Let's calculate the following values for Natural Selection:
Net Income:
Net Income = Earnings before interest and taxes - Interest expense - Taxes
Net Income = $132 million - $28.6 million - ($132 million * 0.4)
Net Income = $132 million - $28.6 million - $52.8 million
Net Income = $50.6 million
Retained Earnings:
Retained Earnings = Net Income - Dividends
Retained Earnings = $50.6 million - ($0.40 * 21.6 million)
Retained Earnings = $50.6 million - $8.64 million
Retained Earnings = $41.96 million
Equity:
Equity = Assets - Liabilities
Equity = $524 million - $212 million
Equity = $312 million
b. To calculate the percentage decline in earnings before interest and taxes that Natural Selection could have sustained before failing to cover, we need to find the breakeven point where Net Income is zero.
Let x be the decline in earnings before interest and taxes as a percentage. Then:
Net Income = Earnings before interest and taxes * (1 - x/100) - Interest expense - (Earnings before interest and taxes * (1 - x/100) - Interest expense) * 0.4
Setting Net Income to zero and solving for x:
0 = Earnings before interest and taxes * (1 - x/100) - Interest expense - (Earnings before interest and taxes * (1 - x/100) - Interest expense) * 0.4
Simplifying the equation:
0 = (1 - x/100) * (Earnings before interest and taxes - Interest expense) - 0.4 * (Earnings before interest and taxes * (1 - x/100) - Interest expense)
Solving for x, we find:
x = 39.2%
Therefore, Natural Selection could sustain a decline of 39.2% in earnings before interest and taxes before failing to cover its expenses.
