This report provides a comprehensive analysis of investment appraisal within the context of International Financial Management (IFM). It begins by evaluating the financial viability of an investment project, calculating Net Present Value (NPV) using both the cost of capital and a hurdle rate, along with the payback period and Accounting Rate of Return (ARR). The report then critically appraises the use of the Payback Method, ARR, and Internal Rate of Return (IRR) as investment appraisal techniques, discussing their advantages and disadvantages. Furthermore, it explores several non-financial variables that a company should consider during investment appraisal, such as current and future legislation, industry standards, relationships with suppliers and customers, and external factors like inflation. The analysis demonstrates the importance of considering both financial and non-financial factors in making informed investment decisions. The report concludes by emphasizing the significance of these techniques in making financial decisions.
