Answer:
Pre-tax = 17.62%
After tax = 12.60%
Explanation:
The pre-tax return is determined by the difference from selling and purchase price, added to received dividends, and then divided by the purchase price:
[tex]R_{PT} = \frac{(117-101)+1.80}{101}\\R_{PT} =0.1762=17.62\%[/tex]
For the after-tax return rate, correspondent dividend and long-term capital gains taxes should be considered:
[tex]R_{AT} = \frac{[(117-101)*(1-0.30)]+[1.80*(1-0.15)]}{101}\\R_{AT} =0.1260=12.60\%[/tex]
