Final answer:
Using the IRR method, Projects 5, 1, and 2 should be accepted first. Under the NPV method, Projects 6, 1, 3, and 5 should be accepted, as they offer the highest combined NPV within the capital budget.
Step-by-step explanation:
When a firm is subject to capital rationing and needs to choose the best projects to invest in, it can use two primary approaches: the Internal Rate of Return (IRR) method and the Net Present Value (NPV) method.
Using the IRR method, a project is considered acceptable if its IRR exceeds the firm's cost of capital, which in this case is 15%. Therefore, the rankings based on IRR from highest to lowest for the projects are:
- Project 5: IRR 20%
- Project 1: IRR 19%
- Project 2: IRR 17%
- Project 3: IRR 16%
- Project 6: IRR 15%
- Project 4: IRR 12%
Therefore, with a budget of $1,000,000, the firm should accept Projects 5, 1, and 2 first, then look to Project 3 or 6 if the budget allows.
Now, when using the NPV method, a project is accepted if its NPV is positive - the higher the NPV, the better the project. The rankings based on NPV from highest to lowest are:
- Project 1: NPV $100,000
- Project 6: NPV $150,000
- Project 3: NPV $60,000
- Project 5: NPV $50,000
- Project 2: NPV $20,000
- Project 4: NPV -$5,000 ( should not be accepted)
With a budget of $1,000,000, using NPV, the firm should accept Projects 6, 1, 3, and 5, as they offer the highest combined NPV without exceeding the capital budget.
