4.19 A 7-year project requires an initial cash injection of $10,000. Expenses of $500 are incurred at the end of every year. The project starts to generate income of $3,000 after 3 years, and the income increases at a rate of 10% every year.
(a) Calculate the yield rate of the project.
(b) Repeat (a), assuming that at the end of each year, the company has to pay 5% tax on investment income after expenses. (If the net income in the year is negative, no tax is paid.) Compare your answer with that obtained in (a).
a. The cash flows of the different years will look like:
Year 0: -10000
Year 1,2: -500
Year 3: 3000 - 500 = 2500
Year 4: 3000 x 1.1 - 500 = 2800
Year 5: 3000 x 1.1^2 - 500 = 3130
Year 6: 3000 x 1.1^3 - 500 = 3493
Year 7: 3000 x 1.1^4 - 500 = 3892.3
So, writing the PV equation, we have:
-10000 = -500/(1+R) - 500/(1+R)^2 + 2500/(1+R)^3 + 2800/(1+R)^4 + 3130/(1+R)^5 + 3493/(1+R)^6 + 3892.3/(1+R)^7
Hence, R = 7.502%.
b. Now, the cash flows will change slightly:
Year 0: -10000
Year 1,2: -500
Year 3: 2500 x 0.95 = 2375
Year 4: 2800 x 0.95 = 2660
Year 5: 3130 x 0.95 = 2973.5
Year 6: 3493 x 0.95 = 3318.35
Year 7: 3892.3 x 0.95 = 3697.685
So, writing the PV equation, we have:
-10000 = -500/(1+R) - 500/(1+R)^2 + 2375/(1+R)^3 + 2660/(1+R)^4 + 2973.5/(1+R)^5 + 3318.35/(1+R)^6 + 3697.685/(1+R)^7
Hence, R = 6.397%
We see that as the tax payments are introduced, the yield becomes less as some of our income is going in paying taxes.
