The equipment upgrades had a mixed impact on Zeta Tube's financial performance. They increased operating income but also led to higher expenses and a negative residual income.
C. Return on Investment for Equipment Upgrades:
1. Calculate the investment in equipment:
Current year total assets - prior year total assets = $4,500 - $1,500 = $3,000
2. Calculate the additional income (operating income increase):
Current year operating income - prior year operating income = $1,687 - $957 = $730
3. Calculate the return on investment (ROI):
ROI = (Additional income / Investment) * 100%
ROI = ($730 / $3,000) * 100% ≈ 24.33%
Interpretation: The return on investment for the equipment upgrades is 24.33%. This means that for every $1 invested in the new equipment, the company generated an additional $0.24 in operating income. While this is not as high as the overall return on investment (37.49%), it is still a positive return and suggests that the investment was generally successful.
Step-by-step explanation:
The equipment upgrades likely led to increased efficiency and production, contributing to the higher operating income in the current year.
However, the increase in expenses associated with the new equipment (e.g., depreciation, maintenance) might have reduced the overall profitability compared to the prior year.
D. Residual Income and Comparison:
1. Calculate the residual income for prior and current year:
Residual income = Operating income - (Cost of capital * Total assets)
Prior year: $957 - (8% * $1,500) = $587
Current year: $1,687 - (8% * $4,500) = -$153
2. Comparison:
The prior year residual income was positive ($587), indicating that the company earned more than the minimum acceptable return on its investments.
However, the current year residual income is negative (-$153), showing that the company's overall return on assets did not meet the desired cost of capital.
Step-by-step explanation:
Although the equipment upgrades improved operating income, they also increased the total asset base (due to the investment), leading to a higher cost of capital and ultimately a negative residual income.
This suggests that while the investment generated additional income, it did not fully cover the expected return on the increased capital employed.
Conclusion:
The equipment upgrades had a mixed impact on Zeta Tube's financial performance. They increased operating income but also led to higher expenses and a negative residual income.
This highlights the importance of carefully evaluating the potential costs and benefits of investments before making decisions.
