Investment appraisal

1⃣ What is Investment Appraisal?

• Definition: A decision-making process used by businesses to evaluate the profitability and risk of an investment project.

2⃣ What are the main methods of Investment Appraisal?

1. Net Present Value (NPV)

2. Accounting Rate of Return (ARR)

3. Payback Period

4. Internal Rate of Return (IRR) (less common in Paper 3 but important to know)

3⃣ What is Net Present Value (NPV)?

• Definition: The sum of all discounted cash flows from an investment, minus the initial investment cost.

• Formula:

  NPV=∑Net Cash Inflows(1+r)n−Initial InvestmentNPV = \sum \frac{Net \ Cash \ Inflows}{(1 + r)^n} - Initial \ InvestmentNPV=∑(1+r)nNet Cash Inflows​−Initial Investment

  where r = discount rate, n = time period.

4⃣ What does a Positive NPV indicate?

• The project is expected to generate more cash than it costs, suggesting it is a good investment.

5⃣ What does a Negative NPV indicate?

• The project is expected to generate less cash than it costs, suggesting it should not be pursued.

6⃣ What is the Payback Period?

• Definition: The time it takes for an investment to generate enough cash inflows to recover its initial cost.

• Formula:

  Payback Period=Initial InvestmentAnnual Cash InflowsPayback \ Period = \frac{Initial \ Investment}{Annual \ Cash \ Inflows}Payback Period=Annual Cash InflowsInitial Investment​

7⃣ How is Payback Period evaluated?

• Shorter payback periods are generally preferred because the investment is recovered faster, reducing risk.

8⃣ What is the Accounting Rate of Return (ARR)?

• Definition: The average annual profit from an investment as a percentage of the initial investment.

• Formula:

  ARR=Average Annual ProfitInitial Investment×100ARR = \frac{Average \ Annual \ Profit}{Initial \ Investment} \times 100ARR=Initial InvestmentAverage Annual Profit​×100

9⃣ How is ARR evaluated?

• The higher the ARR, the more attractive the investment is.

• Must be compared to the cost of capital or required rate of return.

🔟 What are the main advantages of NPV?

1. Considers time value of money.

2. Shows the absolute value of the project's profitability.

3. Directly correlates with the objective of maximizing shareholder wealth.

1⃣1⃣ What are the main disadvantages of NPV?

1. Relies on estimates of future cash flows and discount rate.

2. More complex to calculate compared to Payback or ARR.

3. May not be useful if the discount rate is hard to determine.

1⃣2⃣ What are the main advantages of Payback Period?

1. Simple and easy to calculate.

2. Useful for assessing liquidity risk.

3. Helps in comparing projects with short-term cash flows.

1⃣3⃣ What are the main disadvantages of Payback Period?

1. Ignores the time value of money.

2. Does not consider cash flows after payback.

3. Only focuses on recovery time, not profitability.

1⃣4⃣ What are the main advantages of ARR?

1. Simple to understand and calculate.

2. Focuses on profitability.

3. Allows easy comparison with other investments.

1⃣5⃣ What are the main disadvantages of ARR?

1. Ignores the time value of money.

2. Based on accounting profit rather than cash flow.

3. Can be misleading if profits are uneven over time.

1⃣6⃣ When is Investment Appraisal used?

• Business expansion

• New product development

• Purchasing new machinery

• Entering new markets

1⃣7⃣ How does sensitivity analysis relate to Investment Appraisal?

• It is used to test the impact of changes in key assumptions like costs, revenues, and discount rates on the outcome of NPV and other methods.

1⃣8⃣ What role does Discount Rate play in NPV?

• Represents the cost of capital or required rate of return.

• A higher discount rate reduces the NPV of future cash flows.

1⃣9⃣ Why is IRR important?

• Definition: The discount rate at which the NPV of an investment is zero.

• If IRR > Cost of Capital, the project is considered profitable.
