Chapter 10, Problem 20PSB

a.

To determine

Ascertain the payback period and unadjusted rate of return (use average investment) for each alternative.

Explanation of Solution

The annual rate of return method:

The annual rate of return is the amount of income which is earned over the life of the investment. It is used to measure the annual income as a percent of the annual investment of the business, and it is also known as the accounting rate of return.

Payback period:

Payback period is the expected time period which is required to recover the cost of investment. It is one of the capital investment method used by the management to evaluate the proposal of long-term investment (fixed assets) of the business.

Ascertain the payback period for each alternative as follows:

Alternative 1:

$\begin{array}{c}\begin{array}{l}\text{Payback period }\\ \text{for alternative 1}\end{array}\}=\frac{\text{Cost of investment}}{\text{Cash flows per year (1)}}\\ =\frac{\$75,000}{\$25,312.50}\\ =2.96\text{ years}\end{array}$

Alternative 2:

$\begin{array}{c}\begin{array}{l}\text{Payback period }\\ \text{for alternative 2}\end{array}\}=\frac{\text{Cost of investment}}{\text{Cash flows per year (1)}}\\ =\frac{\$100,000}{\$41,875}\\ =2.39\text{ years}\end{array}$

Ascertain the unadjusted rate of return for each alternative as follows:

Alternative 1:

$\begin{array}{c}\text{Unadjusted rate of return = }\frac{\text{Average increase in net income}}{\left(\frac{\text{Net cost of original investment}}{2}\right)}\\ =\frac{\$6,562.50}{\left(\frac{\$75,000}{2}\right)}\times 100\\ =\frac{\$6,562.50}{\$37,500}\times 100\\ =17.50\%\end{array}$

Alternative 2:

$\begin{array}{c}\text{Unadjusted rate of return = }\frac{\text{Average increase in net income}}{\left(\frac{\text{Net cost of original investment}}{2}\right)}\\ =\frac{\$16,875.00}{\left(\frac{\$100,000}{2}\right)}\times 100\\ =\frac{\$16,875.00}{\$50,000}\times 100\\ =33.75\%\end{array}$

Working note:

Calculate the amount of cash flow per year for both alternatives:

Particulars	Alternative 1	Alternative 2
Cash revenue	62,500	106,250
Less: Cash expenses	35,000	58,750
Amortization expense	18,750(4)
Depreciation expense		25,000 (5)
Income before tax	8,750	22,500
Income tax expense	2,187.5(2)	5,625(3)
Net Income	6,563	16,875
Add: Amortization expense	18,750
Add: Depreciation  expense		25,000
Cash flow per year	25,312.5	41,875.0

Table (1)

(1)

Calculate the amount of income tax expense for alternative 1:

$\begin{array}{c}\begin{array}{l}\text{Income tax expense}\\ \text{for alternative 1}\end{array}\}=\text{Rate of tax}\times \text{Income before tax}\\ =\frac{25}{100}\times \$8,750\\ =\$2,187.5\end{array}$

(2)

Calculate the amount of income tax expense for alternative 2:

$\begin{array}{c}\begin{array}{l}\text{Income tax expense}\\ \text{for alternative 2}\end{array}\}=\text{Rate of tax}\times \text{Income before tax}\\ =\frac{25}{100}\times \$22,500\\ =\$5,625\end{array}$

(3)

Calculate the amount of amortization expense for alternative 1:

$\begin{array}{c}\begin{array}{l}\text{Amortization expense}\\ \text{for alternative 1}\end{array}\}=\frac{\text{Acquisition cost – Salvage value}}{\text{Useful life}}\\ =\frac{\$75,000-0}{\text{4 Years}}\\ =\$18,750\end{array}$

(4)

Calculate the amount of depreciation expense for alternative 2:

$\begin{array}{c}\begin{array}{l}\text{Depreciation expense}\\ \text{for alternative 2}\end{array}\}=\frac{\text{Acquisition cost – Salvage value}}{\text{Useful life}}\\ =\frac{\$100,000-0}{\text{4 Years}}\\ =\$25,000\end{array}$

(5)

b.

To determine

Indicate the investment alternative that is recommendable and explain the reason behind it.

Explanation of Solution

Indicate the investment alternative that is recommendable and explain the reason behind it as follows:

From the above calculation it is clear that alternative 2 appears better than alternative 1. This is because alternative 2 has a shorter payback period and higher unadjusted rate of return, while alternative 1 has a higher payback period and shorter unadjusted rate of return.
