This assignment delves into the core concepts of corporate finance, specifically focusing on the methods used to analyze potential investments. The solution addresses two key questions: the various techniques available for investment analysis and the justification for the superiority of the Net Present Value (NPV) method. The assignment outlines several methods including Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period (PBP), Discounted Cash Flow (DCF), Profitability Index (PI), and Accounting Rate of Return (ARR), providing a concise explanation of each. The solution then argues for the supremacy of NPV, highlighting its ability to rank projects, account for all cash flows, consider the cost of capital and risk, and provide a clear measure of value creation. The assignment concludes by referencing several academic sources to support the analysis.
