(a) To calculate the minimum level of EBIT, we need to find the return on equity (ROE) before and after the capital restructuring.
Before the restructuring, the capital structure is 100% equity, so the ROE is equal to the return on assets (ROA).
ROA = EBIT / Total Assets
Since there is no debt, Total Assets = Total Equity = $40 * 1 million shares = $40 million
So, ROA = EBIT / $40 million
After the restructuring, the capital structure is 83.3% debt and 16.7% equity. The return on equity is calculated as follows:
ROE = (EBIT - Interest) / Equity
Equity = $40 * 1 million shares = $40 million
Interest = 12% * $25 million = $3 million
ROE = (EBIT - $3 million) / $40 million
The restructuring is expected to increase the ROE, so we can set the two ROE equations equal to each other and solve for EBIT:
EBIT / $40 million = (EBIT - $3 million) / $40 million * 0.167
EBIT = $9.6 million
Therefore, the minimum level of EBIT that XYZ's management must be expecting is $9.6 million.
(b) There are many causes of uncertainty or risk for the estimated cash flows of a project, including:
1. Market Risk: Changes in market conditions can affect the demand for a product or service, which can impact the revenue and cash flows of a project.
2. Economic Risk: Changes in macroeconomic factors such as inflation rates, interest rates, and exchange rates can affect the cost of materials, labor, and financing, which can impact the cash flows of a project.
3. Political Risk: Changes in government policies, regulations, or instability can affect the business environment and the cash flows of a project.
4. Operational Risk: Uncertainties in the operations of a project such as delays, equipment failure, and labor disputes can affect the timing and amount of cash flows.
5. Financial Risk: Uncertainties in the financing of a project such as changes in interest rates, credit ratings, and availability of funding can affect the cash flows of a project.
6. Technological Risk: Changes in technology or obsolescence can affect the competitiveness and profitability of a project.
7. Environmental Risk: Changes in environmental
